[0030] According to an operation status of the printing equipment 10 and the continuous feeding and cutting device 2 of this disclosure as shown in FIGS. 1 to 2, one end of the continuous form paper 100 is inserted into the paper fixing wheel 23, and the processing unit (not shown in figures) controls the driving part 2245 to engage the driven part 2246 when the processing unit (not shown in figures) receives a printing information of start, so that the driven part 2246 is driven to rotate by the linking gear 121 and the driving part 2245, the continuous form paper 100 is transferred to the curved guide 241 by the paper picking module 22, and the continuous form paper 100 is then performed a curved manner corresponding to a shape of the curved guide 241 and then transferred to the inlet 11. Finally, the continuous form paper 100 is transferred into the printer 1 for printing.

[0031] Then, the printer 1 and the processing unit (not shown in figures) calculate a printing length of the continuous form paper 100 according to a requirement of a printed data when the paper sensor 27 detects a leading edge of the continuous form paper 100.

[0032] When the paper sensor 27 further detects a length of the continuous form paper 100 is equal to the printing length or a length of the continuous form paper 100 calculated by the processing unit (not shown in figures) calculates is equal to the printing length, the processing unit (not shown in figures) controls the cutting mechanism 26 to cut the continuous form paper 100, and the processing unit (not shown in figures) meanwhile controls the driving part 2245 to separate from the driven part 2246, namely that the continuous feeding and cutting device 2 stop transferring the continuous form paper 100. When the continuous feeding and cutting device 2 stops transferring the continuous form paper 100, the feeding mechanism 12 keeps transferring the continuous form paper 100 into the inlet 11 until the printed data is completely printed by the printer 1.

[0033] According to FIG. 2, if the feeding mechanism 12 keep transferring the continuous form paper 100 into the inlet 11 when the continuous feeding and cutting device 2 stop transferring the continuous form paper 100, the feeding mechanism 12 provides a larger pulling force to the continuous form paper 100 and further moves the continuous form paper 100 far from the curved guide 241. At the same time, the paper presser 25 has the spring 253 providing buffering force for keeping pressing the continuous form paper 100, so that the continuous form paper 100 is prevented from skew or being pulled, the continuous form paper 100 can be printed and cut at the same time without pulling, and printing errors or imperfections caused by pulling is avoid.

[0034] Additionally, the continuous form paper 100 is transferred between the upper pulley 231 and the lower pulley 232 when passing through the cutting mechanism 26, the continuous form paper 100 is limited at specific position by the upper pulley 231 and the lower pulley 232, so that the continuous form paper 100 is prevented from cutting failure caused by insufficient tension if the continuous form paper 100 is too thin or too soft. The upper cutter 261 is cooperated with the lower cutter 262 to cut the continuous form paper 100 with a predetermined length.

[0035] Accordingly, the continuous feeding and cutting device 2 may be additionally disposed on the inlet 11 of the printer 1 to allow the printer 1 to print, cut and print and cut at the same time. Moreover, the continuous feeding and cutting device 2 is capable of cutting automatically, it is convenient for a user to take the printed document, and the printer 1 is also prevented from damaged caused by too many unprinted continuous form papers 100 contained in the printer 1.

[0036] Additionally, the paper picking module 22 of this disclosure has the electromagnetic clutch 2241 which is capable of engaging the linking gear 121 and rotated with the linking gear 121 when powered on, so that it is more power efficient compared with the related art which uses a stepper motor for driving the paper picking module 22 to pick paper sheet.

[0037] Moreover, the paper presser 25 is disposed between the he fixed seat 251 and the pressing pulley 252 for an elastic supporting by the spring 253, thereby driving the pressing pulley 252 to press the continuous form paper 100 and keep the printer 1 to print and pick paper continuously. However, the moment of cutting the continuous form paper 100 when the paper picking module 22 stops transferring the continuous form paper 100, the continuous form paper 100 may be prevented from pulling via a buffer in the horizontal direction caused by a rotation of the pressing pulley 252 and a buffer in the vertical direction caused by a compression or an extension of the spring 253. Therefore, the continuous feeding and cutting device 2 can stably transfer and cut the continuous form paper 100.

[0038] According to FIG. 3 showing a paper picking module 22 according to another embodiment of this disclosure, the embodiment shown in FIG. 3 is similar to the embodiment shown in FIGS. 1 to 2. The difference between the embodiment shown in FIG. 3 and the embodiment shown in FIGS. 1 to 2 is that the paper picking module 22 further has a stepper motor 225 connected to the driving wheel 221 for driving the driving wheel 221.

[0039] Further explanation is described following. Comparing with the embodiment of FIGS. 1 to 2, the electromagnetic clutch 2241 for engaging the linkage gear 121 and rotating with the linkage gear 121 when powered on is omitted in this embodiment. Instead, a stepper motor 225 is applied for driving the paper picking module 22 to pick paper sheet.

[0040] In addition, the processing unit (not shown in figures) is electrically connected to the stepper motor 225. When the processing unit (not shown in figures) controls a rotation speed of the stepper motor 225 when receiving the printing information.
