A sheet discharge apparatus includes a sheet stacking portion on which a sheet discharged by a discharging portion is stacked, and a control portion configured to control a moving unit such that a height position of an uppermost sheet stacked on the sheet stacking portion becomes a first height position. In a case where a sheet detection portion detects that the height position of the uppermost sheet is above a second height position, the control portion sets a sheet discharge speed of the discharging portion to a first sheet discharge speed. In a case where the sheet detection portion detects that the height position of the uppermost sheet becomes lower than the second height position, the control portion controls the sheet discharge speed to be a second sheet discharge speed faster than the first sheet discharge speed.

An image forming apparatus includes an ejecting port, an ejected sheet tray and a guiding member. The ejected sheet tray has a sheet stacking face inclined upwardly towards a downstream side from a lower side of the ejecting port. The guiding member is provided at a position on the sheet stacking face to contact with a tip end of the ejected sheet at the position. The guiding member includes a base member attached to the sheet stacking face, a movable guide for stacking the ejected sheet and a biasing member. The movable guide is turnably supported on the base member around a supporting shaft. The biasing member is interposed between the base member and the movable guide at an upstream side from the supporting shaft to bias the movable guide upwardly. The movable guide is turned downwardly against a biasing force of the biasing member by weight of stacked sheets.

Provided is an apparatus provided with a collection tray for receiving a discharged sheet and shifting, a discharge unit (binding unit constituting a part of a sheet processing apparatus) for discharging a sheet, a shift rail (up-and-down rail including an up-and-down rack) provided in the discharge unit to permit a shift of the collection tray corresponding to a sheet collection amount of the collection tray, a drive member (up-and-down motor) that shifts the collection tray along the shift rail, and an extension rail capable of being added and set onto the shift rail to extend a shift range of the collection tray. By this means, it is possible to increase a collection amount of sheets relatively with ease.

An image forming apparatus includes a display unit, an image forming unit, a detecting unit to detect whether a sheet is on the tray, a moving unit to cause the tray to ascend and to descend to a lower limit position per a tray sheet amount, and a determination unit to determine that tray descent is interrupted at a position located higher than the lower limit position. At the lower limit position, a screen prompting tray sheet removal is displayed. When the tray descent is interrupted, a screen is displayed to include a tray sheet removal prompt and a notice that an obstacle presents under the tray, an image forming process is stopped, and then the tray is caused to ascend when the sheets are not on the tray and then the image forming process is resumed, even if the obstacle presents under the tray.

A cashbox is provided with a movable latch that is driven by a banknote to a blocking position if an attempt to phish a stacked banknote from the cashbox occurs. The latch arrangement is easily pivoted in one direction from a neutral position to a clear position during stacking of a banknote. If an attempt is made to phish a stacked banknote, the banknote being phished causes rotation of the latch arrangement from the neutral position to a banknote inlet blocking position retaining the banknote in the cashbox.
