A stacking device which stacks a sheet includes a stacking unit on which the sheet is configured to be stacked, a regulating member, a moving member, and a restricting member. The regulating member is provided to be movable in a first direction and a second direction, which is a direction opposite to the first direction, and to regulate a position of the sheet stacked on the stacking unit. The moving member moves in a direction that is the same as a moving direction of the regulating member in accordance with the regulating member. The restricting member restricts movement of the moving member. So that the regulating member moves independently of the moving member, the restricting member restricts the movement of the moving member in a partial range of a range in which the regulating member moves.

A sheet conveying device includes: a sheet cassette including a first housing, a pressing plate, a raising plate, a first resilient member, and a second resilient member; a second housing; a sheet-cassette accommodating portion; a first electrode; a second electrode; a sheet conveyor; a driver; a first output device that outputs a first signal and a second signal; a second output device that outputs a rotation pulse signal; and a controller that receives the first signal, the second signal, and the rotation pulse signal. The controller counts pulses of the rotation pulse signal received from the second output device, determines the number of pulses of the rotation pulse signal, and determines an amount of upward movement of the pressing plate based on the number of pulses of the rotation pulse signal.

A sheet feeding device has a sheet feed tray, a metallic pressure plate configured to support the plurality of sheets, the sheet feed tray being rockable about a rocking fulcrum between a descending position and an ascending position, a sheet feed roller configured to convey sheets supported by the pressure plate in a sheet conveying direction one by one, and an elastic member made of metal and arranged on the sheet feed tray, the elastic member engaging with the pressure plate and being electrically connected to the pressure plate, the elastic member contacting metal arranged outside the sheet feed tray to ground the pressure plate. The pressure plate has an engaging part configured to engage with the elastic member, the engaging part displacing in a direction where a contact pressure with respect to the elastic member increases when the pressure plate displaced from the descending position to the ascending position.

A printing device includes, in one example, a media output system including a mezzanine level including a plurality of media support members, the mezzanine level being intermediate to a floor level and a media output level; wherein the plurality of media support members move orthogonally relative to a print media path so that a number of finishing processes may be performed on print media accumulated on the number of media support members.

A sheet storage apparatus according to an embodiment of the present invention includes a receiving unit which receives a sheet that is discharged from a discharge port at a position below the discharge port, and a sheet butting unit which is provided in the vicinity of the receiving unit and receives a front end portion of the sheet. The sheet butting unit has a projection which is provided on at least one of an inner side surface and an inner upper surface of the sheet butting unit. The projection is configured to be capable of retaining a state of regulating vertically upward movement of the front end portion of the sheet being discharged from the discharge port.

An image forming apparatus includes a stacking unit, an access detecting unit, a malfunction detecting unit, a counting unit, and a process deciding unit. The stacking unit receives, as stacked, a recording material. The access detecting unit detects an access to the stacking unit by an operator. The malfunction detecting unit detects that a conveyance malfunction of the recording material has occurred on a conveying path guiding the recording material supplied from the stacking unit. The counting unit counts, after the access detecting unit detects an access to the stacking unit by the operator in a state that the malfunction detecting unit does not detect that the conveyance malfunction has occurred, the number of the conveyance malfunction detected by the malfunction detecting unit. The process deciding unit decides a process to address the conveyance malfunction based on the number of the conveyance malfunction counted by the counting unit.

Provided is a multi-banknote cassette with a movable stopper, which is capable of storing various kinds of banknotes at the same time. The multi-banknote cassette includes a movable stopper which is installed in a stack guide for guiding banknotes introduced into a cassette body of the banknote cassette toward a banknote stopper, and rotated to protrude from or retreat into a transfer path of the banknotes. When a banknote having a relatively small size among the banknotes inserted into the banknote cassette is introduced, the movable stopper is rotated to protrude from the stack guide and regulates the front end of the introduced banknote, and when a banknote having a relatively large size is introduced, the movable stopper is rotated to retreat into the stack guide, and a banknote stopper installed at the rear of the stack guide regulates the front end of the introduced bank.

A paper feed apparatus includes: a sheet tray on which sheets are stacked; a sheet attractor which is located above the sheet tray and attracts sheets one by one from the above; a leading edge fan which is located in a leading edge side of the sheets and blows separation air against leading edges of the sheets to separate an uppermost sheet of the sheets closest to the sheet attractor from lower sheets located below the uppermost sheet; a sheet conveyor which is located in a downstream side of the sheet attractor along a conveying direction of the sheets to convey the uppermost sheet which is attracted by the sheet attractor and separated from the lower sheets by the leading edge fan; and a lifting member which is detachably provided on the sheet tray to support a tail side of a back of the sheets.

Disclosed is a paper sheet storage cassette (for example, banknote collection cassette 42) that includes: a stacking unit (for example, ascending/descending stage 46) in which paper sheets (for example, banknotes) inserted into the paper sheet storage cassette from the outside are stacked in a layered state; a stacking wheel 44 configured to send paper sheets inserted into the paper sheet storage cassette from the outside, one by one, to the stacking unit; a paper sheet passing space (for example, banknote passing space 48) through which the paper sheets to be sent into the stacking unit by the stacking wheel 44 pass; and an inhibiting portion 50 configured to inhibit the paper sheets stacked in the stacking unit from being moved toward the paper sheet passing space.

A sheet feeding device includes a device body including a stopper portion and a feeding tray detachably mounted to the device body. The feeding tray includes a stopper, a lock assembly, and an operating member. The stopper includes a stopped portion movable between a stop position at which the stopped portion is stopped by the stopper portion and a release position. The lock assembly prevents drawing of the feeding tray from the device body. An operating member rotates from an initial state by a predetermined angle to move the stopped portion from the stop position to the release position. The lock assembly restricts rotation of the operating member when the lock assembly is locked. The stopped portion is movable from the stop position to the release position with an operation of mounting the feeding tray to a mount position of the device body without rotation of the operating member.
