A sheet conveyance guide includes a door provided to be pivotable between an open state and a close state and permitting access to an operation portion, a releasing portion provided on the door, configured to abut with the operation portion on a guide plate positioned at a second position along with movement of the door and release a guide plate held by a holding portion, and a pressing portion provided on the door and configured to press the operation portion such that the guide plate is positioned at the first position. In addition, a retraction portion is provided on the door and configured to retract the pressing portion from a moving locus of the operation portion in moving the guide plate from the first position to the second position by abutting with the operation portion of the guide plate moving from the second position to the first position and swinging.

A first cover moves between a first closed position and a first open position. The first cover is located at another end of a housing when the first cover is located at the first closed position. A second cover moves between a second closed position and a second open position. The second cover is located closer to one end than the first cover is at the first closed position and at the second closed position. A first portion of a first conveyance path is formed between the first cover and the second cover at the first closed position and at the second closed position. A second portion of a second conveyance path is formed at a side of the second cover facing the one end at the second closed position. When the first cover opens the first portion, the second cover is located at the second closed position.

A media processing device includes: a hopper for supporting a stack of media units (e.g. cards), the hopper including (i) a gate wall configured to abut leading edges of the media units and (ii) an outlet defined at an end of the gate wall; a pick roller at the outlet for engaging an outer one of the media units in the stack and dispensing the outer media unit from the hopper to a media processing path; the gate wall including a flexible gate at the outlet, the flexible gate configured to deflect toward the media processing path responsive to the outer media unit being driven into the flexible gate by the pick roller, wherein the outer media unit deflects when passing by the flexible gate, permitting the outer media unit to be dispensed from the hopper.

A printing apparatus includes, in a printing apparatus main body, a cover configured to open and close a housing portion configured to house a recording medium, and a first support shaft and a second support shaft configured to rotatably support the cover. The first support shaft is disposed in a position closer to the printing unit than to the housing portion, and the second support shaft is disposed in a position farther from the printing unit than from the housing portion. The cover is configured such that, when displaced from a closed position in a first direction, the cover is rotationally movable around the first support shaft up to a first open position, and that, when the cover is displaced from the closed position in a second direction, the cover is rotationally movable around the second support shaft up to a second open position.

A rotating body unit includes a rotating body and a frame body. The frame body includes a pair of bearing portions. A mounting portion includes a pair of opposing walls facing each other in a width direction, a mounting space formed between the opposing walls, a pair of bearing support members, and a pair of biasing members. The bearing support members are supported by the opposing walls to be movable in the width direction. The biasing members bias the bearing support members inward in the width direction. When the rotating body unit is inserted into the mounting space, the bearing portions abut on a pair of guide surfaces of the bearing support members and move the bearing support members from support positions to retraction positions, and the bearing support members move from the retraction positions to the support positions to support the bearing portions.

A rotating body unit includes a pair of bearing portions and a first engagement portion. A pair of bearing support members support the bearing portions when at support positions, and release the bearing portions when at retraction positions. An auxiliary tool includes a pair of arm portions and a second engagement portion. When the auxiliary tool is engaged with the rotating body unit mounted in the mounting portion, the arm portions abut on and move the bearing support members from the support positions to the retraction positions. The second engagement portion engages with the first engagement portion after the bearing support members move to the retraction positions. As the auxiliary tool is separated from the mounting portion with the second engagement portion engaging with the first engagement portion, the rotating body unit is pulled out of the mounting space integrally with the auxiliary tool.

An image forming apparatus includes an image forming portion, a reversing portion configured to reverse the sheet received through a first feeding passage by feeding the sheet in a first direction and then in a second direction opposite to the first direction, a sheet feeding portion provided in a second feeding passage branching from the first feeding passage on a side upstream of the reversing portion with respect to the first direction, a first guiding surface forming the second feeding passage for guiding a first surface of the sheet fed by the feeding portion, and a second guiding surface for guiding a second surface, opposite from the first surface, of the sheet fed from the reversing portion in the second direction. The second guiding surface is movable with movement of the first guiding surface for opening the second feeding passage.

In an image forming apparatus, a sheet is guided into a first conveyor path or a second conveyor path selectively when a first cover is in a closed position, and is ejected onto the first cover when the first cover is in an open position. Upon power-up, a controller causes a first conveyor roller to rotate but if the first cover is in the open position, when a sheet sensor detects a sheet, the controller does not cause a second conveyor roller to rotate, and causes a flapper to swing from a first position to a second position, and when a front end of the sheet reaches a position downstream of an upstream end of the flapper in a conveyance direction of the sheet conveyed by the first conveyor roller, the controller causes the flapper to swing from the second position to the first position.

Sheet collating device for accumulating sheets from at least one hopper, comprising: a lower transport path and an upper transport path; a switchable guide for directing the sheets from the at least one hopper to the lower or the upper transport path; left and right upper drive shafts connected to a right and a left upper drive pulleys supporting a pair of upper belts, a drive direction of the pair of upper belts being changed dependent on what transport path of the upper and lower transport paths is selected; first and second lower drive shafts connected to a right and a left lower drive pulleys supporting first and second pairs of lower belts; and a first series of right paddles mounted on the first pair of lower belts and a first series of left paddles mounted on the second pair of lower belts for registering a collated set of sheets.

A sheet guiding device includes a cover unit, a swing guide, a link member, and a contact member. The cover unit is configured to be openably disposed on a housing of an image forming apparatus. The swing guide is configured to move between a guide position at which the swing guide is open to guide a sheet and a retracted position at which the swing guide is closed. The swing guide is configured to move from the retracted position to the guide position along with closing movement of the cover unit. The link member has one end configured to be held by the housing and an opposite end engaged with the swing guide. The contact member is disposed on the cover unit. The contact member is configured to contact the link member to rotate the link member in the closing movement of the cover unit.
