A sheet feeding device includes a housing, a sheet storage cassette, a slide rail and an upper contact member. The housing has a pair of inner walls facing each other. The sheet storage cassette is attached between the inner walls in an insertable and drawable manner along a first direction. The sheet storage cassette has a pair of wall parts facing the pair of inner walls. The slide rail includes an outer rail and an inner rail. The outer rail extends along the first direction on the inner wall and the inner rail extends along the first direction on the wall part. The inner rail is supported by the outer rail in a movable manner. The upper contact member is provided on the wall part and moves on an upper face of the outer rail when the sheet storage cassette is inserted and drawn with respect to the housing.

A stacking device which is detachably attached to an apparatus body of an image forming apparatus having an abutting member that abuts on a recording material and on which a recording material is stacked includes: a first supporting unit that supports the recording material from a lower side of the recording material; and a second supporting unit that supports an end of the recording material in an attachment/detachment direction of the stacking device. The second supporting unit includes a corresponding region, and a position of the corresponding region agrees with a position of the abutting member abut with the recording material in a width direction which is orthogonal to the attachment/detachment direction. At least a height of the corresponding region in a direction orthogonal to the attachment/detachment direction and the width direction is lower than a height of the abutting member.

A medium aligning device includes a stacking tray that stacks a medium discharged by a discharge section that discharges the medium, a side end aligning portion that is movable in a width direction that is a direction intersecting with a medium discharge direction of the discharge section, and positions and aligns a side end in the width direction of the medium stacked on the stacking tray, a rear end aligning portion that is movable in the width direction and positions and aligns a rear end that is an upstream end of the medium stacked on the stacking tray in the discharge direction, and a transmission portion that transmits the movement of the side end aligning portion in the width direction to the rear end aligning portion, in which a play in the width direction is provided between the side end aligning portion and the transmission portion.

A tray drawer and a multi-function printer using the same are provided. The drawer includes a tray body, a handle and an elastic element. The handle is connected to the tray body and includes a handle portion and a first engagement portion. The first engagement portion is connected to the handle portion, wherein when the tray body is at a lock state, the first engagement projects from a first position-limit portion. The elastic element connects the first engagement portion to the tray body. There is no relative motion between the first engagement portion and the handle portion.

The sheet storage cassette is attached between the inner walls in an insertable and drawable manner along a first direction. The sheet storage cassette has a pair of wall parts facing the pair of inner walls. The slide rail includes an outer rail and an inner rail. The outer rail extends along the first direction on the inner wall and the inner rail extends along the first direction on the wall part. The inner rail is supported by the outer rail in a movable manner. The upper contact member is provided on the wall part and moves on an upper face of the outer rail when the sheet storage cassette is inserted and drawn with respect to the housing.

A medium conveyance path switching device include: a support unit located at a branch point of a conveyance path at which a conveying direction for a medium converges from three directions; a gate assembly including gates to guide the medium to different conveyance paths at the branch point; and a rotation mechanism configured to selectively rotate the gates. The support unit includes: a first support piece having a first through-hole portion; a second support piece having a second through-hole portion and disposed on one side of the first support piece; a third support piece having a third through-hole portion and disposed on the other side of the first support piece; a first bending connection part pivotably connecting one end of the first support piece and the second support piece; and a second bending connection part pivotably connecting the other end of the first support piece and the third support piece.
