A sheet stacker includes a sheet conveyor arrangement and a stacker platform. The sheets are fed in a sheet feeding direction on the stacker platform, to form stacks of sheets thereon. The stacker platform supports a stack conveyor configured and controlled to move in a conveyor direction to move the stack under formation such that sequentially piled up jobs are placed in an approximately centered position one with respect to the other according to the sheet feeding direction.

The present invention relates to a stacker module (28) for a folder-gluer machine (1). The stacker module comprises a loading surface (90) configured to receive a plurality of folding boxes and to descend vertically as the number of folding boxes on the loading surface increases, and a linearly movable ejector (76) configured to be moved from a retracted position (RP) to an extended position (DP). The stacker further comprises an upper guide (110), configured to move between a clearing position (CP) which is vertically distant from the upper surface of the stack, and a guiding position (GP), in which the upper guide is located closer to the upper surface of the stack, and wherein the upper guide is in the guiding position when the ejector is moved from the retracted position to the evacuation position.

A media stacker may comprises a stacking platform; and a pair of a guiding tracks above the stacking platform and extending from a media receiving side of the media stacker in a media advance direction along opposite sides of a media transport path; wherein at least one guiding track of the pair of guiding tracks is movable between a support position and a release position to guide and support the media sheet above the stacking platform and to release the media sheet to drop from the guiding track to the stacking platform.

A sheet tray, including a tray body having a bottom plate, and a sheet guide, is provided. The sheet guide includes a guide plate to align sheets at a predetermined position, a lever, a swingable device having a boss and a guide groove, and a stopper pivotably connected with a hinge. The boss guided in the guide groove moves the lever between a first position, wherein the boss is in a first section in the guide groove and the stopper is lowered to an engaged position, with an engageable part being engaged with the bottom plate; and a second position, wherein the boss is in a second section in the guide groove and the stopper is uplifted to a separated position with the engageable part being separated from the bottom plate. When the lever moves from the first position to the second position, the lever tilts by ascending and pivoting.

A sheet tray provided with first and second trays respectively having first and second supporting surfaces. The second tray slidably assembled, in a first direction, to the first tray. The first and second supporting surfaces are configured to support sheets thereon. The first tray and the second tray have a first guide portion and a second guide portion which are formed at central parts, in a second direction perpendicular to the first direction, respectively. The second guide portion is configured to slidably contact the first guide portion to guide the slide movement of the second tray. A first separation regulating part formed on the first guide portion, and a second separation regulating part formed on the second guide portion are configured to engage with each other in the vertical direction to prevent separation of the first and second trays in the vertical direction, exceeding a particular dimension.

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.

The sheet feeding apparatus includes a first cursor. The first cursor comes in contact with a side face of a stack of sheets, and can move between a restriction position and a retracted position. The lift plate includes a fixed plate and a movable plate. The stack of sheets is movable together with the movable plate in the push-in/pull-out direction. When the sheet storage unit is pushed into the apparatus body, the first cursor moves by inertia of the stack of sheets, against an urging force of an urging member, toward the retracted position. After the sheet storage unit has reached the accommodated position, the first cursor pushes the stack of sheets by resilience of the urging member to move to the restriction position.

A sheet feeding apparatus includes a sheet containing unit and a sheet feeding device to feed sheets in the sheet containing unit. The sheet containing unit includes a main body to hold sheets, a drawer member capable of being drawn from the main body, a restricting member movable in a direction parallel to a sheet feeding direction, a first retaining member disposed at the main body, and a second retaining member disposed at the drawer member. The drawer member holds the sheets together with the main body when drawn from the main body. The restricting member restricts an upstream end position of the contained sheets. The first retaining member retains the restricting member at a first position. The second retaining member retains the restricting member at a second position.

A buffer means includes a buffer unit that makes paper sheets temporarily stand by and a paper stacking unit that intermittently conveys paper sheets and sucks the trailing edges of the paper sheets to stack the paper sheets stepwise and make them temporarily stand by.
