To provide an image forming apparatus having a sheet processing apparatus installed in an in-body space, capable of discharging sheets of different sizes without interfering with discharge operation of the sheet processing apparatus in a compact configuration. An image forming apparatus has a sheet binding unit disposed in an in-body space part thereof, a first conveying path for conveying the sheet discharged to the in-body space part toward the sheet binding unit, and a second conveying path for conveying the sheet discharged to the in-body space part toward a second stack tray that stacks thereon the sheet vertically below a first stack tray disposed outside the in-body space part. The second conveying path extends, inside the in-body space part, substantially horizontally between an image forming part and the sheet binding unit.

A sheet conveyance device of an embodiment includes a carrying-in unit feeds a sheet to a stacking unit; a lower conveyance unit applies a force to a lower side of a sheet stacked on the stacking unit to move the sheet; a lifting and lowering unit lifts and lowers at least an end of the lower conveyance unit on a side close to the carrying-in unit in at least three stages (lower, middle, and upper); an upper conveyance unit faces the lower conveyance unit and applies a force to the upper side of a sheet pinched between the upper conveyance unit and the lower conveyance unit that is moved to the upper stage to move the sheet; and a stopper protrudes above the lower conveyance unit placed at the lower stage by the lifting and lowering unit, and the downstream end in the feeding direction of a sheet abuts on the stopper.

A post-processing device includes a processing tray, an aligning plate, a transport section, a feeding section, and a pressing section. A sheet before being subjected to stapling processing by a stapler is to be mounted on the processing tray. The aligning plate aligns ends of a plurality of sheets. The transport section transports the sheet toward the aligning plate. The feeding section is provided between the transport section and the aligning plate and feeds the sheet in a transport direction. The pressing section is provided between the transport section and the aligning plate and applies, to the sheet, a pressing force having a component in a direction opposite from the transport direction. Further, the pressing section applies the pressing force to the sheet before the feeding section applies a feeding force to the sheet.

A sheet discharge device includes: at least one processor; a conveyance unit configured to convey a sheet along a conveyance path; a discharge unit to which the sheet is discharged; a storage unit that is provided in a middle of the conveyance path and temporarily stores the sheet; an alignment unit provided in the discharge unit and configured to align the sheet in a width direction intersecting a convey direction of the sheet, in which the processor is configured to change a method of aligning the sheets by the alignment unit between a case where storage control for storing the sheets in the storage unit is performed and a case where the storage control is not performed.

Various embodiments of a paper feed and tray extension system for adapting printer components to accommodate election document dimensions are disclosed herein. To accomplish this, a printer feed adapter system includes a paper tray extension for implementation within an existing printer that extends a paper tray to enable the paper tray to receive sheets of paper that have required dimensions for election documents. Further, paper catch extender extends a paper catch to enable the paper catch to catch election document sheets following processing by the printer.

A sheet post-processing apparatus includes an apparatus body, a body frame, a sheet conveyance passage, an elevating tray, and an elevating unit. The elevating unit has a pair of rails. The body frame has a plurality of vertical frame members extending in the vertical direction and horizontal frame members that extends in a horizontal direction and is joined to the plurality of vertical frame members. The pair of rails are formed integrally with, among the plurality of vertical frame members, a pair of vertical frame members provided corresponding to a second side surface.

A recording material processing apparatus includes a guide shaft of which an axial direction extends in a recording material width direction intersecting a discharge direction of a recording material, and an alignment unit that moves along the guide shaft, in which the alignment unit includes a bearing portion that is movably fitted onto the guide shaft, an alignment portion that is provided to be exposed at an outer side in the discharge direction and comes into contact with an end surface of the recording material that is parallel to the discharge direction from an outer side of the recording material to align a position of the end surface, an arm portion that connects the bearing portion and the alignment portion to each other, and a protruding portion that protrudes from a surface of the arm portion to a position outside the recording material in the axial direction of the guide shaft and comes into contact with a surface of a device main body, which is parallel to the discharge direction, in a case where an external force is applied to the alignment unit with the alignment unit being at a position close to the surface.

A loading unit includes a processing tray, alignment units, and a paddle. In the processing tray, a medium is placed. The alignment units are disposed an interval in a Y direction to align a downstream tip end in a positive A direction of the medium. The paddle moves the medium that has been fed onto the processing tray toward the alignment units. A coefficient of friction of a contact surface of the alignment unit is higher than a coefficient of friction of a front face of the alignment unit, and the contact surface is positioned downstream of the front face in the positive A direction.

A sheet containing apparatus includes a first container unit that contains a sheet having a first size and that tilts with respect to a horizontal direction such that a first end and a second end in a width direction of the apparatus are located at different heights with the first container unit installed in a sheet containing apparatus body when viewed in a first direction, and a covering portion that is movable to a covering position at which the covering portion covers at least a part of the first container unit in the first direction and an open position at which the covering portion uncovers the first container unit in the first direction. When viewed in the first direction, a tilting division line is adjacent to the first container unit and tilts with respect to the horizontal direction, and at least a whole of the tilting division line is covered by the single covering portion in the first direction with the covering portion positioned at the covering position.
