DETAILED DESCRIPTION OF THE INVENTION

[0032] This disclosure will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

[0033] Please refer to FIGS. 1, 1a, 2a and 2b. FIG. 1 shows a peripheral electronic device having an automatic document feeder according to this disclosure. FIG. 1a is a schematic view showing an operation interface in a copying method according to a first embodiment of this disclosure. FIGS. 2a and 2b are system block diagrams showing a copying method according to this disclosure. This disclosure provides a copying method. When a user uses an input tray 132 disposed on an automatic document feeder (ADF) 13 of a peripheral electronic device 1 and places an information medium on the input tray 132 to perform a copy operation on the information medium (to copy the information medium), the copying method selects the option data of copying a first side, a second side or both sides (the first and second sides) of the information medium to operate. The peripheral electronic device 1 comprises the automatic document feeder 13, a control panel 10, a processor 11, a storage 17 and an output unit 18. The automatic document feeder 13 comprises the input tray 132 for supporting the information medium. The control panel 10 comprises operation buttons 12, 14 and 16 for selecting one or multiple image acquiring sides (the image sides, the data pages or the printed sides wanted by the user) of the information medium. The processor 11 (see FIG. 2a) is connected to the automatic document feeder 13, an image acquiring assembly 19 and the operation buttons 12, 14 and 16. The storage 17 is electrically connected to the processor, and comprises at least one image module 173, which stores program codes for enabling the image acquiring and storing operations on the one or multiple images of the image acquiring side or sides of the information medium. The output unit 18, which may be an output port, is electrically connected to the processor 11, and receives and outputs the one or multiple images of the image acquiring side or sides of the information medium. The processor 11 controls the image acquiring assembly 19 to acquire the one or multiple images of the image acquiring side or sides of the information medium according to the program codes and different signals of the operation buttons 12, 14 and 16 on the control panel 10, and transmits the image or images to the output unit 18.

[0034] The different signals outputted by the operation buttons 12, 14 and 16 on the control panel 10 correspond to different image sub-modules 171 and 172 and the image module 173 or different image acquiring sub-assemblies of the image acquiring assembly 19. The output unit 18 comprises a printer, a fax machine, an external storage transmission port or a network transmission port. It is worth noting that the peripheral electronic device 1 may be generalized as an image acquiring device. In this case, the output unit 18 may not be a printer or a fax machine, or is even omitted. So, the copying method of the image acquiring device does not necessarily comprise outputting the information medium in the form of a physical copy.

[0035] The automatic document feeder 13 further comprises a detector 131, which is disposed at an input end of the input tray 132 and detects whether the information medium is present. When the detector 131 detects the presence of the information medium, the configuration of the copying method starts. The option of the above-mentioned image acquiring side(s) of the information medium may be a first side operation button 12 corresponding to the first side of the information medium, a second side operation button 14 corresponding to the second side of the information medium, or a duplex operation button 16 corresponding to the first side and the second side. The operation buttons may also be presented as options on a display. In one embodiment, when the detector 131 detects the information medium, setting options of the image acquiring side(s) of the image module are enabled. In the fifth embodiment of FIG. 3, an option corresponds to an image sub-module. For example, the first side operation button 12 is set to transmit a first signal to the processor 11 to enable a first portion of the program codes stored in a first image sub-module 171 to control the image acquiring assembly to acquire the image of the first side (top side) of the information medium; the second side operation button 14 is set to transmit a second signal to the processor 11 to enable a second portion of the program codes stored in a second image sub-module 172 to control the image acquiring assembly to acquire the image of the second side (bottom side) of the information medium; and the duplex operation button 16 is set to transmit a third signal to the processor 11 to enable the program codes of the first image sub-module 171 and the second image sub-module 172 to control the image acquiring assembly to acquire the images of the both sides (top and bottom sides) of the information medium. Of course, this embodiment may directly enter the mode of setting the image acquiring side as the user triggers the operation buttons of the image acquiring side(s) without the provision of the detector for detecting the presence of the information medium.

[0036] In another embodiment, when the detector detects the presence of the information medium, the setting options of the image acquiring side(s) are enabled. In the fifth embodiment of FIG. 3, the selection of the image acquiring side(s) of the information medium on the control panel is controlled by one single image module 173 without being established by multiple image sub-modules. For example, the first side operation button 12 is set to transmit the first signal and start the single image module 173 (loading the program codes) to start a first image acquiring sub-assembly 23 at a first time point t1 to scan the first side (top side) of the information medium; the second side operation button 14 is set to transmit the second signal and start the single image module 173 to start a second image acquiring sub-assembly 25 at a second time point t2 to scan the second side (bottom side) of the information medium; and the duplex operation button 16 is set to transmit the third signal and start the single image module 173 to start the first image acquiring sub-assembly 23 at the first time point t1 and to start the second image acquiring sub-assembly 25 at the second time point t2 to scan the both sides (top and bottom sides) of the information medium. Of course, this embodiment can directly enter the mode of setting the image acquiring side as the image side operation button is triggered without the provision of the detector for detecting the presence of the information medium.

[0037] Once the copying method starts, the information medium starts to enter the sheet passage, wherein the transporting of the information media may start from the topmost or bottommost information medium.

[0038] The first side operation button 12, the second side operation button 14 and the duplex operation button 16 are used to let the user clearly identify the image acquiring side(s) of the data page to be selected without the confusion that the data page is disposed on the input tray with the image acquiring side facing upward or downward. The duplex operation button 16 may be presented in the form of a text, texts, a graphic or a combination of texts and graphic. For example, in this embodiment, the first side operation button 12, the second side operation button 14 and the duplex operation button 16 are commonly expressed in the form of graphic and texts, which may also be regarded as a graphic. Thus, the image acquiring side to be operated is clearly indicated, and the timesaving and environment protective effects can be achieved.

[0039] In this embodiment, three operation buttons are provided. The first side operation button 12 is used to transmit the first signal, and the corresponding function thereof is to acquire the image of the first side of the information medium. The second side operation button 14 is used to transmit the second signal, and the corresponding function thereof is to acquire the image of the second side of the information medium. The duplex operation button 16 is used to transmit the third signal, and the corresponding function thereof is to acquire the duplex image of both sides of the information medium. For instance, the first side is a top side (side up) of the information medium, the second side is a bottom side (side down) of the information medium, and the both sides are the both sides (top and bottom sides) of the information medium. It is worth noting that a single operation button can be used to replace three operation buttons, wherein the single operation button can transmit three different signals to let the processor start acquiring and storing the image(s) of the first side, the second side or the first side and the second side of the information medium in the image module. For example, pressing the operation button one time indicates that the first side is acquired, pressing the operation button two times indicates that the second side is acquired, and pressing the operation button three times indicates that the first side and the second side are acquired. Alternatively, continuously pressing the operation button to output a prompt tone indicates that the first side is acquired, continuously pressing the operation button to output two prompt tones indicates that the second side is acquired, and continuously pressing the operation button to output three prompt tones indicates that the first and second sides are acquired.

[0040] FIG. 1b is a schematic view showing an operation interface in a copying method according to a second embodiment of this disclosure. In FIG. 1b, the first side operation button 12, the second side operation button 14 and the duplex operation button 16 of the information medium are commonly expressed by the graphic and the texts. Although a panel 15 is long and narrow and can only display the texts, the operation of the user of selecting the image acquiring side(s) of the information medium is not affected.

[0041] Please refer to FIG. 1c. FIG. 1c is a schematic view showing an operation interface in a copying method according to a third embodiment of this disclosure. In this embodiment, a first side operation button 12′, a second side operation button 14′ and a duplex operation button 16′ of the information medium are expressed by the text. After the user clearly selects image acquiring side(s) to be operated according to the indication, the program codes of the corresponding image module are loaded to start operating.

[0042] FIGS. 1d to 1f are schematic views showing operation interfaces in a copying method according to a fourth embodiment of this disclosure. Please refer to FIG. 1d, in this embodiment, the keys on the control panel 10 are used to operate the image acquiring side(s) of the information medium, wherein the options of the image acquiring sides correspond to the first side operation button 12 and the duplex operation button 16, and control the image acquiring side(s) of the information medium. If the user wants to acquire the simplex image (top side) of the information medium, then the user places the image side facing upward, and presses the first side operation button 12. Then, the electronic device performs the simplex image acquiring of the information medium with the image side facing upward. If the user wants to acquire the duplex data image, then the user places the information medium arbitrarily, and presses the duplex operation button 16 so that the electronic device performs the duplex image acquiring.

[0043] Please refer to FIG. 1e, in this embodiment, the operation buttons on the control panel 10 are used to operate the image acquiring side(s) of the information medium, wherein the options of the image acquiring sides correspond to the second side operation button 14 and the duplex operation button 16, and control the image acquiring side(s) of the information medium. If the user wants to scan the simplex image (bottom side) of the information medium, then the user places the image side facing downward, and presses the second side operation button 14 so that the electronic device performs the simplex image acquiring of the information medium with the image side facing downward. The technical contents of acquiring the duplex image data are shown in FIG. 1d.

[0044] Please refer to FIG. 1f, in this embodiment, the operation buttons on the control panel 10 are used to operate the image acquiring side(s) of the information medium, wherein the options of the image acquiring sides correspond to the first side operation button 12 and the second side operation button 14, and control the image acquiring side(s) of the information medium. If the user wants to scan a top side of the information medium, then the user places the image side facing upward, and presses the first side operation button 12 so that the electronic device performs the simplex image acquiring of the information medium with the image side facing upward. If the user wants to scan a bottom side of the information medium, then the user places the image side facing downward, and presses the second side operation button 14 so that the electronic device performs the simplex image acquiring of the information medium with the image side facing downward. If the user wants to scan the top and bottom sides of the information medium, then the user places the image side arbitrarily, and presses the first side operation button 12 and the second side operation button 14 in the same time period so that the electronic device performs the duplex image acquiring. The user may firstly keep pressing one of the operation buttons, and then press the another operation button to provide the duplex scan indication. Alternatively, the user may press and release one of the operation buttons, and then press another operation button again within a predetermined time (e.g., 2 seconds). At this time, the predetermined time set by the electronic device has not elapsed, and the electronic device starts to perform the duplex scan. If another operation button is not pressed within the predetermined time, then only the simplex scan is performed. Alternatively, after the user presses and releases one of the operation buttons, the electronic device immediately starts the scan. However, the information medium is still being transported on the way or the electronic device is still warming up, so the user has the sufficient time to press another operation button again as long as the image acquiring assembly 19 can timely perform the duplex scan.

[0045] At least one of the operation buttons of the first to third embodiments is electrically connected to a simplex image acquiring sub-assembly (such as symbol 33 in FIG. 3a) facing upward or downward when the information medium is disposed in or on the input tray 132, and another one of the operation buttons is electrically connected to duplex image acquiring sub-assemblies (e.g., symbols 23 and 25 in FIG. 3) of the image acquiring assembly. This disclosure provides a way of making the user conveniently and clearly know how to place the information medium with the data page facing the correct image acquiring side to prevent the try and error.

[0046] Please refer to FIG. 3. FIG. 3 is a schematic view showing a copying system according to a fifth embodiment of this disclosure. In this embodiment, an image acquiring sub-assembly is disposed on each of two sides of the passage of the sheet-feeding mechanism assembly 20. So, the copying system of this embodiment comprises a first image acquiring sub-assembly 23 and a second image acquiring sub-assembly 25. This disclosure further provides a copying system for selecting to copy an information medium using the first side operation button 12, the second side operation button 14 or the duplex operation button 16. The copying system comprises: an automatic document feeder 13 comprising an input tray 132 for supporting an information medium or information media, on which scanning (image acquiring) and storing operations are to be performed; a control panel 10 using one or multiple operation buttons 12, 14 and 16 to display images of a first side option, a second side option and a duplex option, which provide copy modes to be selected by the user for the setting to perform the image acquiring and storing operations on the first side, the second side and the first side and the second side of the information medium, wherein an image acquiring assembly operates according to a corresponding signal outputted by the setting of the option of the operation button. The first side operation button 12 (corresponding to the first side option) outputs a first signal, the second side operation button 14 (corresponding to the second side option) outputs a second signal, and the duplex operation button 16 (corresponding to the duplex option) outputs a third signal (duplex acquiring signal) to the processor, so that the processor controls the image acquiring assembly to operate (acquire the image/images of the first side and/or the second side of the information medium). The operations of the image acquiring assembly further comprise acquiring the image of the first side at a first time point t1, or/and acquiring the image of the second side at a second time point t2.

[0047] The image acquiring assembly further comprises the first image acquiring sub-assembly 23 for acquiring the image of the first side of the information medium, and the second image acquiring sub-assembly 25 for acquiring the image of the second side of the information medium. The processor controls the first image acquiring sub-assembly 23 to operate at the first time point t1; and controls the second image acquiring sub-assembly 25 to operate at the second time point t2.

[0048] In this embodiment, when the third signal is enabled, the operations at the first time point t1 and the second time point t2 are mutually independent from each other. If the first image acquiring sub-assembly 23 and the second image acquiring sub-assembly 25 are disposed opposite each other, the first time point t1 is different from the second time point t2 due to the design of the image acquiring technology.

[0049] In another technical solution, the user can select a copy mode, a first image sub-module 171 corresponds to the first signal of the first side operation button 12 and a second image sub-module 172 corresponds to the second signal of the second side operation button 14 of the information medium. Different signals of the operation buttons on the operation panel correspond to different image modules 171 and/or 172.

[0050] When the detector detects the presence of the information medium, the information medium is transported to a passage “ab” between the passage ports “a” and “b” and the image acquiring is performed. The control panel 10 displays or configures images or texts representing the first side operation button 12, the second side operation button 14 and the duplex operation button 16 copying the information medium to provide copy modes to be selected by the user. The first image sub-module 171 enables the first image acquiring sub-assembly 23 to perform the image acquiring of the first side operation button 12 through a first light-permeable window 21 when the processor correspondingly detects the first signal of the first side operation button 12 for copying the information medium. The second image sub-module 172 enables the second image acquiring sub-assembly 25 to perform the image acquiring of the second side operation button 14 through a second light-permeable window 24 when the processor correspondingly detects the second signal of the second side operation button 14 for copying the information medium. When the detector detects the presence of the information medium on the input tray, the setting and selecting mode is entered. When the image acquiring of the information medium is finished, the detector on the input tray does not detect the presence of the information medium on the input tray. At this time, the selecting mode is set back to the original state. The image acquiring methods of the first image sub-module 171 and the second image sub-module 172 are mutually independent from each other. It is also possible to use the same image module 173 but different signals for enabling the first image acquiring sub-assembly 23 and the second image acquiring sub-assembly 25 at different time points to perform the image acquiring and storing operations.

[0051] The same effect may be achieved in another embodiment, wherein the image acquiring assembly comprises the first image acquiring sub-assembly 23 and the second image acquiring sub-assembly 25. The program codes of the first image sub-module 171 control the first image acquiring sub-assembly 23 to perform the image acquiring and storing operations on the first side of the information medium according to the first signal of the first side operation button 12. The program codes of the second image sub-module 172 control the second image acquiring sub-assembly 25 to perform the image acquiring and storing operations on the second side of the information medium according to the second signal of the second side operation button 14. The processor enables the first image acquiring sub-assembly 23 and the second image acquiring sub-assembly 25 at the same time or different times according to the third signal of the duplex option.

[0052] When the copying system detects the third signal in this embodiment, the processor enables the first image acquiring sub-assembly 23 and the second image acquiring sub-assembly 25. Regarding the system control, the processor enables the first image sub-module 171 and the second image sub-module 172 at the same time or different times.

[0053] Please refer to FIGS. 3a and 3b. FIGS. 3a and 3b are schematic views showing a copying system according to a sixth embodiment of this disclosure. In this embodiment, an image acquiring sub-assembly 33 is disposed on a passage of a sheet-feeding mechanism assembly 30. So, the operation object of this embodiment is to provide an operation method of the technical contents of a single image acquiring assembly. Thus, this disclosure further provides a copying system using the first side operation button 12, the second side operation button 14 or the duplex operation button 16 to select to copy an information medium. The copying system comprises: an automatic document feeder 13 comprising an input tray 132 for supporting an information medium or information media to be acquired; a control panel 10 using the operation buttons 12, 14 and 16 to display the texts or images of the first side image option, the second side image option and the duplex image option for setting to perform the image acquiring and storing operations on the first side, the second side and the first side and the second side of the information medium to provide copy modes to be selected by the user. The image acquiring assembly operates according to a corresponding signal outputted based on setting of one of the options of the operation buttons. The first side operation button 12 outputs a first signal, the second side operation button 14 outputs a second signal, and the duplex operation button 16 outputs a third signal to operate the image acquiring assembly. The operation of the image acquiring assembly further comprises acquiring the image of the first side at the first time point t1, or acquiring the image of the second side at the second time point t2.

[0054] In the above-mentioned paragraph, if the control panel utilizes the technique of FIG. 1d or 1e, then similar effects still can be achieved. So, this disclosure further provides a copying system using a duplex operation button 16, and the first or second side operation button 12 or 14 to select to copy the information medium. The copying system comprises: an automatic document feeder 13 comprising an input tray 132 for supporting an information medium to be acquired; a control panel 10 using a duplex operation button 16 and at least one operation button 12 or 14 for displaying the image-acquiring side facing upward or downward to display the texts or images of the first side image option, the second side image option and the duplex image option for setting to perform the image acquiring and storing operations on the first side, the second side and the first side and the second side of the information medium to provide copy modes to be selected by the user. The image acquiring sub-assembly operates according to a corresponding signal outputted based on setting of one of the options of the operation buttons. The first side operation button 12 outputs a first signal or the second side operation button 14 outputs a second signal, and the duplex operation button 16 outputs a third signal to the processor, so that the processor controls the image acquiring assembly to operate. The operation of the image acquiring assembly further comprises acquiring the image of the first side at the first time point t1, or acquiring the image of the second side at the second time point t2.

[0055] At the first time point t1 and the second time point t2, the processor controls the image acquiring sub-assembly to operate to acquire the duplex image of both sides of the information medium through different input paths.

[0056] This disclosure further provides a copying system using the first side operation button 12, the second side operation button 14 or the duplex operation button 16 to select to copy the information medium. The copying system comprises: a detector for detecting the information medium on the input tray, wherein when the detector detects presence of the information medium, the information medium is transported to the passage “cd” between the passage ports “c” and “d” and the passage “dd” between the passage ports “d” and “d” for image acquiring; a control panel 10 using the first side operation button 12, the second side operation button 14 and the duplex operation button 16 to provide copy modes to be selected by the user; a first image sub-module 171 for correspondingly detecting the first signal of the first side operation button 12 to enable the image acquiring sub-assembly 33 to acquire the image of the information medium in the passage “cd” through a light-permeable window 31 at the first time point t1; a second image sub-module 172 for correspondingly detecting the second signal of the second side operation button 14 to enable the image acquiring sub-assembly 33 to acquire the image of the information medium on the passage “dd” through the light-permeable window 31 at the second time point t2. When the processor detects the duplex operation button 16 as being pressed, the processor loads the program codes to operate the first image sub-module and the second image sub-module at the same time or different times.

[0057] The program codes of the first image sub-module 171 can enable the image acquiring sub-assembly 33 to acquire the image of the information medium in the passage “cd” through the light-permeable window 31. The program codes of the second image sub-module 172 can enable the image acquiring sub-assembly 33 to acquire the image of the information medium, which is discharged from, fed into and further flipped over and discharged from the passage port d (passage “dd”) through the light-permeable window 31. It can be obtained that when the first image sub-module 171 is enabled (the processor loads its program codes), the image acquiring sub-assembly 33 operates as the information medium passes through the passage “cd”; and when the second image sub-module 172 is enabled (the processor loads its program codes), the image acquiring sub-assembly 33 is disabled when the medium passes through the passage “cd”, and is enabled to acquire the image data of the side of the information medium facing downward when the medium passes through the passage “dd”.

[0058] When the copying system detects the third signal, the information medium firstly passes through the path of the passage “cd” to make the enabled image acquiring sub-assembly 33 acquire the image of the first side of the information medium; and then passes through the path of the passage “dd” from the passage port d (outlet) to make the enabled image acquiring sub-assembly 33 acquire the image of the second side of the information medium. Thus, the images of the both sides of the information medium can be acquired. So, the image acquiring sub-assembly 33 operates twice in this embodiment.

[0059] Please refer to FIG. 4, FIG. 4 is a flow chart showing a copying method of a peripheral electronic device according to a seventh embodiment of this disclosure. A detector 131 is disposed at an inlet of the input tray 132 of the automatic document feeder 13. In step 101, the detector automatically detects an information medium disposed at the automatic document feeder. In step 102, the detector transmits a detection signal to the processor. In step 104, the processor enables the image side option on the control panel 10 to enter a standby state. For example, the option is disposed on the touch panel or the indicators of the physical operation button are triggered to emit light or flicker to remind the user to make a selection, wherein these indicators do not emit light or flicker when no information medium is present to save the energy and reduce the light pollution. In step 105, the user selects the image side(s) (image acquiring side(s)) to be operated according to the indication of the image side option. In step 106, the image side signal of the image side option selected by the user is transmitted to the processor. In step 107, the processor enables the corresponding module or modules (e.g. the image extracting module storing the image acquiring program codes, and the printing module storing the printing program codes) according to the image side signal to control the image acquiring (scanning) assembly and printer assembly. Alternatively, the image acquiring (scanning) assembly and the image acquiring program codes may be regarded as a module, or the printer assembly for storing the printing program codes is regarded as another module to perform a copy operation. Of course, the subsequent image acquiring or copying operation of the information medium may also be continued according to the image side signal. In this embodiment, when the user places the information medium in the input tray 132 of the automatic document feeder 13, the detector detects the presence of the information medium and transmits the message to the processor, and the processor correspondingly enables the associated page selecting option of the information medium on the control panel. Thus, the user can clearly obtain which side or sides are to be copied without the try and error.

[0060] The image side option is an operation button, operation buttons, an image or images presented on the touch panel. Multiple operation buttons are preferably used. If the image option or graphic option on the touch panel is used, the text(s), image(s) or icon(s) for clearly indicating the first side, the second side or the both sides may be used.

[0061] The technological essence of this disclosure is to clearly and instinctively indicate the operation side options. So, the image side options may show at least one option indicating the image acquiring side of the information medium facing upward or downward, and show a duplex option to achieve the effect of this disclosure.

[0062] The image side options provide the operation side option to the user, and different options enable different signals to be transmitted to the processor to start the corresponding operation. It can be obtained that if there are two options, then two signals represent the option of copying the image acquiring side of the information medium facing upward or downward, and the duplex copy option, respectively. If there are three options, three signals represent the options of copying the image acquiring sides of the information medium facing upward and downward, and the duplex copy option, respectively. The signals enable the corresponding module or modules or time control method to achieve the corresponding copying requirement. In addition, the image side option may provide the user with multiple options of operation sides, and the options of the operation sides enable different signals to be transmitted to the processor to start the corresponding operations, respectively.

[0063] Please refer to FIG. 5. FIG. 5 is a flow chart showing a copying method of a peripheral electronic device according to an eighth embodiment of this disclosure. A detector is disposed at an inlet of the input tray 132 of the automatic document feeder 13. In step 201, the detector automatically detects the presence of a document of an information medium disposed at the automatic document feeder. In step 202, the detector transmits the detection signal to the processor. In step 203, the processor enables the duplex scan mode, and stores the acquired image sides (e.g., the images of the first and second sides) in the buffer of the image acquiring device. In step 204, the processor enables the image side option on the control panel 10 to enter a standby state. In step 205, the user selects one or multiple image sides to be copied according to the indication of the image side option. In step 206, the image side signal of the image side option selected by the user is transmitted to the processor. In step 207, the processor enables the corresponding module or modules (e.g., the printing module storing the printing program codes for controlling the printer assembly) according to the image side signal to perform a copy operation. In this embodiment, when the user places the information medium on or in the input tray 132 of the automatic document feeder 13, the detector detects the presence of the information medium and transmits the message to the processor. The processor enables the automatic image acquiring instruction to firstly store the image sides of the information medium facing upward and downward into the buffer, and enables the options of the image sides to be selected by the user. If there are multiple information media, then the copying system only scans the first information medium and then stops transporting other information media to make the image side options enter a standby state. Thus, the user can clearly select the pages to be copied. For example, the user can effectively study or understand how to select the image side in the waiting time during which the first information medium is scanned. In addition, when there are other information media, or the user further places other information media within a predetermined time (e.g., 5 to 10 seconds), the processor further enables the corresponding module or modules (e.g. the image extracting module storing the image acquiring program codes, and the printing module storing the printing program codes for controlling the image acquiring (scanning) assembly and the printer assembly, respectively) according to other detection signals of the detector detecting the presence of other information media and the image side signals to perform the copy and image acquiring operations on other information media. For example, the front side, reverse side or both-side image acquiring or copying operation for the subsequent information medium is performed according to the copy option of the first information medium. This configuration is suitable for the state where a lot of information media are to be copied and the input tray cannot accommodate so much information media at a time.

[0064] FIG. 6 is another example showing the peripheral electronic device having an automatic document feeder 1′ according to this disclosure. As shown in FIG. 6, the peripheral electronic device 1′ is similar to FIG. 1 except for the difference that the input tray 132 of the automatic document feeder 13 is in a substantially upright state. It is worth noting that the input tray 132 of the automatic document feeder 13 may also have the completely upright state. In the above-mentioned state, the user has to judge whether the image side of the information medium faces frontward or backward or both images side of the information medium are to be copied. FIG. 6a is a schematic view showing an operation interface in a copying method according to a ninth embodiment of this disclosure. The embodiment is similar to FIG. 1a except for the difference that the patterns or graphic icons of the operation buttons 12, 14 and 16 can make the user clearly understand the front side, the back side or the both sides. FIG. 6b is a schematic view showing an operation interface in a copying method according to a tenth embodiment of this disclosure. The embodiment is similar to FIG. 1c except for the difference that the texts of the operation buttons 12′, 14′ and 16′ can make the user understand the front side, the back side or the both sides. It is worth noting that the above-mentioned FIGS. 1b, 1d to 1f are also applied to the peripheral electronic device of FIG. 6.

[0065] In this embodiment, the image side option can be enabled when the processor receives the signal of the detector detecting the presence of the information medium, or after the processor receives the acquired image side of the information medium.

[0066] FIG. 7a is a system block diagram showing a copying method according to an eleventh embodiment of this disclosure. FIGS. 7b and 7c are schematic views showing an operation interface of two examples of the copying method according to the eleventh embodiment of this disclosure. As shown in FIGS. 7a and 7b, the control panel 10 of this example further comprises a start button 48 for transmitting a second signal S2 to the processor 11, and the operation button (image acquiring side selecting button) is one single operation button 46 for transmitting the first signal S1 to the processor 11. In FIG. 7b, the operation button 46 is a simplex image acquiring selection button providing the indication to the user that the image acquiring side faces upward (in another example, the indication provided to the user indicates that the image acquiring side faces downward), and the start button 48 is to start the copying operation. When the processor 11 receives the first signal S1 and the second signal S2 (for example, the user firstly presses the operation button 46, and then presses the start button 48, or simultaneously presses the two operation buttons), the processor 11 controls the image acquiring assembly 19 to acquire only the image of the first side. That is, the user has to select the image acquiring side(s) firstly, and then enable the image acquiring operation. When the processor 11 receives only the first signal S1 and does not receive the second signal S2 (for example, the user only presses the operation button 46), the image acquiring assembly 19 is disabled and continuously waits for the user's indication. Of course, the start button 48 may output the optical or audio message to guide the user to press down the start button 48. That is, the user's operation of selecting the image acquiring side(s) cannot start the image acquiring operation. When the processor 11 receives only the second signal S2 and does not receive the first signal S1 (for example, the user only presses the start button 48), the processor 11 controls the image acquiring assembly 19 to acquire the images of the first side and the second side. That is, the default starting mode of the whole image acquiring device is a duplex image acquiring mode. Thus, a simple operation method may also be provided.

[0067] The example of FIG. 7c is similar to that of FIG. 7b except for the difference that the default starting mode of the whole image acquiring device is a simplex image acquiring mode, the operation button 46 is a duplex image acquiring selection button providing the indication of both image acquiring sides to the user. Thus, when the processor 11 receives the first signal S1 and the second signal S2, the processor 11 controls the image acquiring assembly 19 to acquire the images of the first side and the second side. When the processor 11 receives only the first signal S1 and does not receive the second signal S2, the image acquiring assembly 19 is disabled and continuously waits for the user's indication. Of course, the start button 48 may output the optical or audio message to guide the user to press down the start button 48. When the processor 11 receives only the second signal S2 and does not receive the first signal S1, the processor 11 controls the image acquiring assembly 19 to acquire only the image of the first side. Thus, another simple operation method may also be provided.

[0068] In summary, this disclosure provides a copying method and a peripheral system using the copying method to facilitate the user in directly and instinctively selecting the image side(s) to be copied according to the images. Thus, it is possible to prevent the to-be-copied data page from being incorrectly placed on the input tray, and to achieve the human-oriented, environment protective and source saving effects.

[0069] While this disclosure has been described by way of examples and in terms of preferred embodiments, it is to be understood that this disclosure is not limited thereto. To the contrary, it is intended to cover various modifications. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications.
