摘要： Provided are a medium ejection apparatus, a control method, and a control program to enable precise determination of whether abnormal ejection of a medium has occurred. A medium ejection apparatus includes an ejection roller to eject a medium, a tray to stack the medium ejected by the ejection roller, a first optical sensor located above the ejection roller and including a first light emitter to emit light toward the tray and a first light receiver to generate a first optical signal based on received light, a second optical sensor located above the ejection roller and including a second light emitter to emit light toward a downstream side of the tray in a medium ejecting direction and a second light receiver to generate a second optical signal based on received light, a determination module to determine whether abnormal ejection of the medium has occurred based on the first optical signal and the second optical signal, and a control module to execute abnormality processing when it is determined that abnormal ejection of the medium has occurred.

摘要： In a medium conveying device, a projector projects light, a projection light amount of the light changes, at every fixed time, to a first projection light amount and a second projection light amount less than the first projection light amount, a receiver receives the light projected from the projector, a processor determines, at fixed sampling timings, whether a reception light amount of the receiver is at a first reception light level or a second reception light level smaller than the first reception light level, determines, when the reception light amount alternately changes to the first reception light level and the second reception light level, that a medium is not present on a conveying path, and determines, when the reception light amount is fixed to either the first reception light level or the second reception light level, that the medium is present on the conveying path.

摘要： A sheet processing apparatus comprising: a conveying unit configured to have a roller that conveys a sheet in a conveyance direction; a first detecting device disposed downstream of the conveying unit in the conveyance direction; a second detecting device disposed downstream of the first detecting device in the conveyance direction; a boring unit configured to have a punch that performs boring in the sheet; and a control unit is used. The first detecting device and the second detecting device each detect passage of a leading edge of the sheet being conveyed. The control unit calculates an actual conveyance speed of the sheet on the basis of detection results of the first detecting device and the second detecting device, and controls rotation of the roller, on the basis of the actual conveyance speed, so that the sheet is conveyed at a predetermined target speed.

摘要： A sheet stacking apparatus includes a frame, a round member directly or indirectly connected to the frame, and an arm directly or indirectly connected to the frame. The arm is rotatable to rotate between a first position and a second position. The arm is positioned to bias sheets toward the round member when in the first position, and the arm is positioned to bias the sheets away from the round member when in the second position.

摘要： A sheet sorting apparatus includes a first tray detachable from an apparatus main body, a second tray arranged below the first tray, a discharge unit to discharge a sheet to the first or second tray, a tray detecting unit to detect that the first tray is detached from the apparatus main body, a full stack detecting unit to detect a fully stacked condition of the first tray, and a control unit to control the discharge unit. In a case where the tray detecting unit detects that the first tray is detached from the apparatus main body, the control unit controls the discharge unit not to discharge a sheet to the second tray when a number of sheets discharged to the second tray reaches a threshold number of sheets, even though the full stack detecting unit does not detect the fully stacked condition.

摘要： An image reading apparatus includes a reading unit, a transport unit that transport a document, a feeding unit that transports the document to the transport unit, a controller that stops the feeding operation of the feeding unit after the leading end of the preceding document transported from the feeding unit reaches the transport unit and restarts the feeding operation after the rear end of the preceding document passes a predetermined position. The controller, restarts the feeding operation a first time after the rear end of the succeeding document following the preceding document passes the predetermined position when a size of the preceding document indicates a first size, and restarts the feeding operation a second time after the rear end of the succeeding document passes the predetermined position where the second time is longer than the first time when the size indicates a second size larger than the first size.

摘要： A sheet discharge apparatus includes a pivot member pivoting in an up-down direction by being pressed by a sheet discharged from a sheet discharging portion, with the pivot member retained by being in contact with an uppermost sheet supported on the sheet supporting portion. A control unit changes a sheet interval between a preceding sheet and a succeeding sheet and executes a first discharge operation in which at least one sheet is discharged, and a second discharge operation in which sheets are discharged by the sheet discharging portion at a first sheet interval such that the pivot member does not contact with an uppermost sheet supported on the sheet supporting portion during the second discharge operation, and the control unit acquires a number of sheets to be discharged in the second discharge operation based on a detected position of the pivot member detected during the first discharge operation.
