A medium drying device includes a transport roller pair as a transport unit that transports a medium and a heat roller pair as one heating unit that heats the medium transported by the transport roller pair and is provided in a transport direction of the medium, in which the medium is configured to be transported to a heating area by the heat roller pair a plurality of times.

In order to properly suppress a discharge defect corresponding to an image ratio of a sheet, in the case where a coefficient of friction is different according to the image ratio of an image on the sheet, an air blowing section is arranged to blow air toward a downstream side in a transport direction from between a downstream-side end portion of a first stacking section and an upstream-side end portion of a second stacking section. When an image ratio of an image on a sheet by an image forming apparatus is a first value, the air blowing section sets an air quantity blown to the sheet at a first air quantity F1, while when the image ratio is a second value higher than the first value, setting the air quantity blown to the sheet at a second air quantity F2 larger than the first air quantity F1.

A post-processing apparatus includes a sheet discharge tray to which a sheet or a sheet bundle is discharged, and a shift mechanism configured to shift a discharge position of the sheet or the sheet bundle discharged to the sheet discharge tray from a reference position. The apparatus further includes a controller configured to control the shift mechanism to divide the sheet or the sheet bundle in a first direction in a direction orthogonal to a conveyance direction of the sheet or the sheet bundle and a second direction opposite to the first direction.

A cash box has a storage area for storing several notes of value and a counterpressure unit, which delimits the storage area and is movable between first and second positions. The cash box includes a sensor unit with at least one sensor element, the sensor unit emitting a sensor signal that is dependent on the position of the sensor element. The counterpressure unit has a recess for receiving at least a part of the sensor element. The sensor element and the recess are arranged such that the sensor element is only received whenever the counterpressure unit is in the first position and no note of value is present between the sensor element and the recess. The cash box has a control unit which determines on the basis of the sensor signal of the sensor unit and the position of the counterpressure unit whether the cash box is empty.

A stapling apparatus including a holding portion that receives and holds a plurality of mediums, a first matching portion positioned downstream of the holding portion, a paddle that applies sending force to the mediums so that leading edge sides of the mediums reach the first matching portion, a stapler that binds the mediums, the leading edge sides of the mediums having been matched by the first matching portion, a folding mechanism portion that folds the mediums that have been bound by the stapler. In the stapling apparatus, the first matching portion is configured to move and is configured to transport the mediums to a performing position of the stapler and a performing position of the folding mechanism portion by moving, and a position where the paddle applies sending force to the mediums differs according to lengths of the mediums in a transport direction.

A medium transport device includes a feeding unit that transports a medium, a stack portion that receives the medium transported by the feeding unit between a support surface for supporting the medium in an inclined posture in which a downstream side in a transport direction is directed downward and an opposing surface opposing the support surface and stacks the medium, an alignment portion that aligns a downstream end of the medium stacked in the stack portion, a paddle that is provided between the feeding unit and the alignment portion in the transport direction and moves the medium toward the alignment portion by rotating while being in contact with the medium, and a control unit that controls an operation of the paddle, in which the control unit controls the operation of the paddle according to a condition.

A sheet processing apparatus includes a sheet tray on which one or more sheets to be processed are placed, an adhesive applying unit, and a pressing member. The adhesive applying unit has an end portion that faces the sheet tray and holds an adhesive material and is configured to move towards the sheet tray up to a position at which the end portion is in contact with or proximate to a sheet on the sheet tray and apart from the sheet tray. The pressing member is configured to move into and out of a moving path of the adhesive applying unit. The pressing member is pressed against a sheet on the sheet tray by the adhesive applying unit, when the pressing member is in the moving path of the adhesive applying unit and the adhesive applying unit moves towards the sheet tray.

A sheet processing apparatus includes an intermediate tray on which a sheet is to be stacked, a stapler to execute stapling processing on the stacked sheet, a discharge tray on which the sheet subjected to the stapling processing by the stapler and discharged from the intermediate tray is to be stacked, a control unit, and a shift unit. The shift unit may shift the sheet to a position on the intermediate tray, wherein the position is outside of a range in which the stapling processing is to be executed. In a state where a first sheet and a second sheet are stacked on the intermediate tray and the second sheet is subject to the stapling processing, the control unit causes the shift unit to shift the first sheet on which the stapling processing is not executed, and causes the stapler to execute the stapling processing on the second sheet.

A sheet processing apparatus includes a conveying portion; a conveying path for sheets conveyed by the conveying portion; a stack portion where sheets discharged from the conveying path are stacked; a first binding portion moving in a crossing direction crossing the conveying direction; a first regulating portion regulating a position of a sheet bundle stacked on the stack portion; a first guide member guiding the first regulating portion; a second regulating portion regulating a position of a sheet bundle on the stack portion in the crossing direction; a second guide member guiding the second regulating portion; a third regulating portion regulating a position of a sheet bundle on the stack portion in the conveying direction; and a second binding portion binding a corner portion of a sheet bundle without a staple. The first binding portion binds a corner portion of a sheet bundle by a staple.

A medium transporting apparatus including a paddle that comes in contact with a medium discharged on a first tray including an upstream end matching member and that rotates to move the medium towards the upstream end matching member, and a low frictional resistance member configured to switch between an advanced state advanced from outside a medium mount region of the first tray to a first region, and a retracted state retracting from the first region to an outside of the medium mount region. The low frictional resistance member is, after a first medium is mounted on the first tray, switched from the retracted state to the advanced state, and is interposed between the first medium and a second medium when, after discharging the first medium, moving the second medium discharged from a pair of discharge rollers towards the upstream end matching member with the paddle.
