Image forming apparatus capable of controlling sheet discharge according to presence or absence of user
11635730 · 2023-04-25 · ·

In an image forming apparatus, a control device functions as a controller and a user presence/absence determiner. When accepting an instruction to execute a print job through a touch panel, the controller controls operations of a sheet feed device, a conveyance device, and an image forming device to allow a document image represented by image data generated by a document reading device to be formed on a sheet to make a printed matter and allow the printed matter to be discharged to a sheet output tray. When the user presence/absence determiner determines that a user is present, the controller controls, before printing for at least a last sheet in the print job, the operations of the sheet feed device and the conveyance device to allow a sheet to be discharged to the sheet output tray without allowing the image forming device to form the document image on the sheet.

Post-processing apparatus
11597621 · 2023-03-07 · ·

A post-processing apparatus includes a conveyance unit, a discharge port, a tray, an elevation unit, a detection unit, and a control unit. The conveyance unit conveys a print medium supplied from an image forming apparatus. The discharge port discharges the print medium conveyed by the conveyance unit. The tray is stacked with the print medium discharged from the discharge port and can be raised and lowered in a vertical direction. The elevation unit raises and lower the tray in the vertical direction. The detection unit detects a top surface of an uppermost print medium of one or more sheets of print media stacked on the tray. The control unit controls the conveyance unit and the elevation unit and hold a relative position of the top surface with respect to the discharge port if the print medium is discharged from the discharge port at a first position. The control unit causes the conveyance unit to convey the print medium at a first speed if a discharge time from a first timing indicating the timing relating to discharge of the print medium from the discharge port to a second timing indicating the timing when the print medium is detected by the detection unit is a first time and causes the conveyance unit to convey the print medium at a second speed different from the first speed if the discharge time is a second time.

ROTATING DEVICE, TRANSPORTING DEVICE, AND IMAGE FORMING APPARATUS

A rotating device includes: a first rotating body capable of forward rotation; a second rotating body capable of forward rotation and reverse rotation; a drive unit outputting drive forces in a forward rotation direction and a reverse rotation direction; and a transmission mechanism transmitting the drive force in the forward rotation direction output from the drive unit to the first rotating body and the second rotating body to rotate the first rotating body and the second rotating body in the forward direction and transmitting the drive force in the reverse rotation direction output from the drive unit to the first rotating body and the second rotating body to rotate the first rotating body in the forward direction and rotate the second rotating body in the reverse direction.
