A photo-interruptor unit includes a photo-interruptor and a supporting portion to detachably support the photo-interruptor. The supporting portion includes a hole which is formed on an attaching surface and through which a hook portion is inserted, and a guide portion to protrude from the attaching surface and guide the hook portion so that it deforms in a deformation direction when the photo-interruptor is moved in a movement direction intersecting an insertion direction. A regulating portion protrudes from the attaching surface and forms continuously with the guide portion to regulate a position in the movement direction of the photo-interruptor. The guide portion includes a first rib portion and a second rib portion that oppose one another in the deformation direction, and a distance between the first rib portion and the second rib portion in the deformation direction narrows toward a downstream direction of the movement direction.

A sheet conveyor unit is connected to downstream side of an upstream side unit in a sheet conveying direction. The sheet conveyor unit includes a convey guide for receiving a sheet discharged from outlet of the upstream side unit. The convey guide is constituted of a pair of guide members disposed to face each other with a predetermined space therebetween. The guide members have the same shape and include base parts having guide surfaces that form a sheet conveying path when combined to face each other, and inclined parts bent to directions apart from the guide surfaces from one end of the base parts in the sheet conveying direction so as to form a receiving port. The convey guide is attached selectively to one of positions different in at least one of a height direction and the sheet conveying direction with respect to an apparatus main body.

A device for printing information at multiple predetermined positions of a flat object including a registration wall, a print module including print nozzles and a print plate and displaceable along an horizontal axis perpendicular to the registration wall, fixed upper drive members for moving the flat object in a direction of transport along the registration wall, the print plate and the fixed upper drive members together forming an upper reference in a vertical direction, and lower pressing members for pressing the flat object against the upper reference, the device further comprises at least one mobile upper drive member and, for avoiding contact with the flat object immediately after printing, the at least one mobile upper drive member is vertically mobile and configured to be moved from a lower to an upper position above the upper reference when the displaceable print module is positioned along the horizontal axis ahead of the at least one mobile upper drive member in the direction of transport.

A recording system includes a printer, a post-processing apparatus, and a first support to be mounted on a floor outside a mounting area of the printer. The printer includes a manual feed tray and an opening/closing portion each configured to be moved outward from a body of the printer to enable a process. The post-processing apparatus is located, in a Z direction, above the manual feed tray and the opening/closing portion that were moved. The first support supports the post-processing apparatus and forms a space in which the manual feed tray and the opening/closing portion are moved.

A sheet feeding device includes a pickup roller, a lifting/lowering mechanism, and a driver device. The lifting/lowering mechanism includes a restricting member that releasably restricts the pickup roller from being lowered from a lifted position of the pickup roller at the lifted position. In the sheet feeding device, the driver device drives the lifting/lowering mechanism so that the pickup roller is lowered from the lifted position of the pickup roller, and a drive suspend operation is performed in which the driving of the lifting/lowering mechanism by driver device is suspended after a predetermined time during which the pickup roller does not contact a sheet loading tray or a sheet on the sheet loading tray elapses from a time point when the pickup roller is released from being restricted by the restricting member at the lifted position.

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.

An image forming apparatus includes a first casing including a transfer unit, a second casing including a fixing unit, and a third casing provided between the first casing and the second casing and including an intermediary feeding member. The first casing includes a first discharging port discharging a recording material with a toner image. The second casing includes a first receiving port receiving the recording material with the toner image. A height from an installing surface of the image forming apparatus to the first receiving port in a vertical direction is different from a height from the installing surface to the first discharging port. The intermediary feeding member of the third casing is provided obliquely in the vertical direction from a second receiving port receiving the recording material from the first discharging port to a second discharging port delivering the recording material to the first receiving port.

An image forming apparatus includes an apparatus body and a moveable unit. The apparatus body includes an image forming device and a restriction portion. The moveable unit includes an image reading device and is detachably attached to the apparatus body. The moveable unit is opened and closed with respect to the apparatus body by rotation about a rotation shaft when the moveable unit is attached to the apparatus body. The moveable unit is attached to and detached from the apparatus body by moving in an axial direction of the rotation shaft. The moveable unit further includes a restricted portion that engages with the restriction portion that restricts a movement of the moveable unit in the axial direction. The restriction portion or the restricted portion further includes a deformation portion having elasticity. The deformation portion is deformed so that the moveable unit is attached to and detached from the apparatus body.

A support spindle assembly for rotatably supporting a coreless paper roll for dispensing, the support spindle assembly including a spindle base, a spindle element having a central longitudinal axis (X) and having first and second ends, the spindle element being attached to the spindle base at the first end and rotationally fixed in relation to the spindle base and a rotatable sleeve rotatably disposed about the spindle element, and rotatable in relation to the spindle base and to the spindle element. The support spindle assembly includes a resilient member disposed about the first end of the spindle element, which resilient member is arranged to cooperate with the spindle base and with the rotatable sleeve in order to provide the rotatable sleeve with a rotational resistance.

A sheet feeding apparatus includes an apparatus body, an opening/closing member supported on the apparatus body, a sheet support supported on the opening/closing member, and a rotary feeding member provided on the apparatus body to feed the sheet supported on the sheet support in a feeding direction. A first engagement member is provided in the apparatus body, and a second engagement member is provided on a downstream end portion of the sheet support in the feeding direction and engages with the first engagement member in a vertical direction that intersects an axial direction of the rotary feeding member when the opening/closing member is positioned at the open position. The rotary feeding member is lowered toward the sheet supported on the sheet support in a case where the opening/closing member is positioned at the open position.
