An information processing apparatus includes a light emitting unit and a light receiving unit for receiving light output from the light emitting unit, and includes a detection unit for outputting a light reception signal indicating that the light receiving unit has received light from the light emitting unit, a driving signal output unit for outputting a driving signal to the detection unit so that the light emitting unit intermittently outputs light, a detection signal output unit for outputting, based on the output driving signal and the output light reception signal, a detection signal indicating whether an object exists between the light emitting unit and the light receiving unit, and a control unit including an interrupt port to which the output detection signal is input and for returning from a power saving state in response to the detection signal being input to the interrupt port in the power saving state.

An image forming apparatus includes an image reading unit. When printing a postcard is selected, a preview screen including a preview image about an image on a communication side of the postcard read by the image reacting unit is displayed on a display. At this occasion, an instruction image indicating an orientation of an address side of the postcard is also displayed. When it is instructed to turn over the preview image on the communication side, the preview screen including the preview image on the address side is displayed on the display. When the orientation of the address side and the orientation of the communication side do not coincide with each other, or when they are not as intended by a user, printing is performed after the image on the communication side is rotated according to the user's operation.

An image processing apparatus performs a binding process for binding a plurality of sheets. When a binding unit configured to bind sheets without using a staple performs the binding process, the image processing apparatus adds a mark for identifying a position where the binding process is performed.

An image scanning apparatus includes an image sensor to scan a manuscript, a transfer apparatus to pick up the manuscript and move the manuscript to a manuscript transfer path, and a loading apparatus to load the manuscript scanned by the image sensor. The loading apparatus includes a discharge tray to hold a discharged manuscript and a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript.

An image reading apparatus includes a scanner, a sensor, and a controller. The sensor is configured to detect an original at a predetermined position. The controller is configured to determine whether or not an immediate execution mode in which no user operation is needed to cause the scanner to start scanning is set, and in case the immediate execution mode is determined to be set, determine whether or not a scan start condition is satisfied. The scan start condition includes the sensor detecting the original at the predetermined position. The controller is configured to control the scanner to start scanning, upon a standby time of a predetermined amount being passed since the scan start condition is satisfied.

An image forming apparatus includes: a reception part that receives specification of a print mode and specification of a sheet type to be used for printing; a sheet supply part that sends a sheet to a sheet conveyance path; a detection part that detects a type of a sheet sent to the sheet conveyance path; and a hardware processor that controls a printing operation, wherein when a sheet type received by the reception part is a type for which printing in the print mode received by the reception part is allowed, the sheet supply part sends a sheet to the sheet conveyance path, the hardware processor determines whether or not the print mode received by the reception part is a prohibition mode, when it is determined that the print mode is the prohibition mode, the detection part detects a type of a sheet sent to the sheet conveyance path.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

A document processing device comprises an input module used to obtain paper feed information, a human-computer interaction interface and a processor. The processor is connected to the input module and the human-computer interaction interface and drives the human-computer interaction interface according to the paper feed information, so that the human-computer interaction interface provides interactive prompt information. The processor executes a document processing mode according to command information after the human-computer interaction interface received the command information. Thereby, the document processing device can provide the interactive prompt information in real time according to the paper feed information, prompt a user to perform corresponding operations and achieve the purpose of improving operational efficiency and ease of use of the document processing device.

A sensor unit includes a sensor device, a holder that holds the sensor device and includes a surface maintained at a reference potential, and a case that houses the holder, in which the case includes a mounting surface in contact with a mounting object, and the mounting surface is provided with a communication portion that causes an inside and an outside of the case to communicate with each other, and the holder includes a protrusion that protrudes from the communication portion and comes in contact with the mounting object.

An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.
