A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

A sheet conveyance apparatus includes a cover unit, a base unit, a roller unit configured to be detachable from the cover unit, and comprising a roller configured to convey the sheet along a conveyance path and a holder comprising an arm portion configured to extend in a width direction orthogonal to a sheet conveyance direction, a cam configured to swing the holder by rotating, and a cover member configured to be openable and closable with respect to the cover unit and configured to cover at least a portion of the arm portion against the conveyance path in a closed state, the cover member being opened by being pressed by the arm portion in a case where the roller unit is detached from the cover unit.

A belt feeding device includes an endless belt, stretching rollers including a tension roller, a bearing member supporting the tension roller, a beating support member supporting the bearing member, an urging member urging the tension roller, a supporting member supporting the bearing supporting member, and a locking member.

The locking member is movable between a first position where an engagement between the locking member and one of the bearing support member and the bearing member is released and the bearing member is permitted to move so as to apply the tension to the belt, and a second position where the locking member locks the bearing member by engaging with the bearing support member and the bearing member and the bearing member is restricted to move. The bearing member, the bearing support member, the urging member, and the locking member constitute a unit to be integrally dismountable from the supporting in the second position.

A drive transmitter includes a first unit including a coupling portion having grooves spaced at an angle of 180 degrees in the rotational direction, and a second unit having projections spaced at an angle of 180 degrees in the rotational direction. The projections are configured to be inserted into the grooves of the coupling portion. The coupling portion has a guiding portion and a non-guiding portion. The guiding portion is sloped, with a height from a bottom face of the grooves decreasing in the rotational direction of the first unit, and is configured to guide the projections to the grooves. The non-guiding portion is disposed at a point symmetrical position to the guiding portion to an axial center of the first unit. One of the projections is not in contact with the non-guiding portion while another one of the projections is in contact with the guiding portion.

A sheet feeding apparatus includes: a conveying roller; a separating roller which forms a nip portion by pressing the conveying roller and separates a sheet conveyed by the conveying roller one by one in the nip portion; a moving portion configured to move a stacking portion from a first position at which a sheet stacked in the stacking portion and a feeding roller are separated from each other to a second position at which the sheet stacked in the stacking portion abuts on the feeding roller; and a cover member which is movable between a third position to cover a rotation shaft of the separating roller and a fourth position to expose the rotation shaft of the separating roller, in which the cover member placed in the fourth position moves to the third position along with movement of the stacking portion from the first position to the second position.

According to one embodiment, an image forming apparatus includes a support shaft, a connecting member, and a detachable member. The support shaft extends in a first direction. The support shaft includes a protrusion. The protrusion protrudes in a second direction orthogonal to the first direction. The connecting member is formed of an elastic material. The connecting member interposes the protrusion therebetween. The connecting member is connected to the support shaft to surround an outer periphery of the support shaft. The detachable member is detachably connected to the support shaft via the connecting member.

A sheet conveying apparatus includes a conveyance unit to convey a sheet, a support frame supporting the he conveyance unit and having a mounting member, and an exterior cover made of metal and fixed to the mounting member by a screw. The exterior cover covers the support frame on a back side of the sheet conveying apparatus and includes a hook portion provided above a position corresponding to the mounting member in a vertical direction, and a positioning pin provided below the position corresponding to the mounting member in the vertical direction. The support frame includes an engagement portion, engaged with the hook portion and provided at a position above the mounting member in the vertical direction, and a through-hole, formed at a position below the mounting member in the vertical direction, into which the positioning pin is inserted to position the exterior cover with respect to the support frame.

A paper sheet handling apparatus includes a transportation member that transports a paper sheet and a rotation shaft member that serves as a center of rotation of the transportation member, wherein the transportation member includes a plurality of elastic loop sections having central axes parallel to the rotation shaft member, and the plurality of loop sections are arranged in a rotation direction of the transportation member such that the plurality of loop sections are each supported by an adjacent loop section when being elastically deformed while contacting the paper sheet.

A sheet conveyance apparatus includes a storage unit storing a sheet, a conveyance member to convey a sheet, a support shaft portion, and a separation unit. The support shaft portion has one end fixed to a main body of the sheet conveyance apparatus and the other end as a free end that is not fixed to the main body. The separation unit pinches and conveys a sheet with the conveyance member and separates a plurality of sheets stored in and fed from the storage unit one by one. The separation unit includes a separation member that is supported by the support shaft portion and rotatable with the support shaft portion, and a holding member to hold the separation member. By moving the holding member in an axial direction of the support shaft portion, the separation unit is removed from the apparatus with the holding member holding the separation member.
