An image reading apparatus includes a stacking portion, a feeding unit, a reading unit, and a discharge portion provided below the stacking portion. The feeding unit feeds a sheet stacked on the stacking portion in a feeding direction. The reading unit reads an image on the fed sheet and the discharge portion discharges the read sheet. The stacking portion includes first and second support surfaces that support the sheet and first and second regulating units to regulate a position of the sheet in a widthwise direction using two opposing ends of the sheet. The second support surface is retractable from a predetermined section above the discharge portion. The first support surface includes a downstream support portion that supports the sheet on a downstream side of the predetermined section in the feeding direction. A part of the second regulating surface is positioned on the downstream support portion.

Provided is a paper sheet replenishing box (paper feed device) for replenishing reserve fund in each circulation-type paper sheet storage unit, wherein paper sheets of each denomination can be replenished from one paper sheet replenishing box in which paper sheets of different denominations having different sizes are accommodated together to a circulation unit of the respective circulation-type paper sheet storage units. The paper sheet replenishing box includes a first tray piece 201 in which a plurality of pieces of first paper sheets P1 are placed in a stacked state, a second tray piece 211 arranged immediately below the first tray piece, on which a plurality of pieces of second paper sheets P2 having a different longitudinal dimension from that of the first paper sheet are placed in a stacked state, and rear-end regulating members 204 and 214 that align front end positions in a transport direction of respective paper sheet bundles to predetermined positions. After all the first paper sheets in a bundle on the first tray piece have been fed by a feed unit 160, an uppermost surface of the second paper sheets in a bundle on the second tray piece becomes a state capable of coming in contact with the feed unit.

Provided is a recording material processing apparatus including: a recording material support portion configured to support a recording material loaded thereon from below; a contact member disposed on a side of the recording material loaded on the recording material support portion and configured to be pushed by an edge portion of the recording material, the contact member being configured to move to a side opposite to the side of the recording material; an elastic member configured to receive a load from the contact member pushed by the edge portion of the recording material; and a member support portion disposed without contacting the recording material loaded on the recording material support portion and configured to support the contact member.

The present invention includes a lift portion lifting and inverting a sheet group including a plurality of stacked sheets and a conveyor portion that moves, along a conveying direction, each sheet transferred from the lift portion, wherein: the lift portion includes frames, a fork portion, an inversion mechanism turning the fork portion to lift and invert the sheet group, and a fork movement mechanism moving the fork portion; the lift portion is equipped with a width direction movement mechanism moving the sheet group in a width direction; and after the sheet group is mounted on the fork portion and before the sheet group is transferred to the conveyor portion, the width direction movement mechanism is controlled on the basis of detection information from a position sensor to center the sheet group within a reference width direction range.

An image forming apparatus includes an image forming portion, a tray rotatably provided on a side surface of a main assembly and including a stacking surface, a feeding portion; and a blowing fan mounted on the tray and generating air blown to a side end of a sheet in a sheet widthwise direction perpendicular to a feeding direction of the sheet by the feeding portion. The blowing fan is disposed on an opposite side to a side where the sheet is stacked on the stacking surface so that a position of at least a part of the blowing fan with respect to the sheet widthwise direction is overlapped with a position of the stacking surface with respect to the sheet widthwise direction.

A sheet storage device for storing sheets includes a supporting unit, a regulation unit, and a moving unit. The supporting unit supports stored sheets. The regulation unit is movably arranged on the supporting unit, and regulates a position of an edge portion of a sheet. The moving unit moves the regulation unit. The moving unit includes moving members to move in a direction parallel to a moving direction of the regulation unit. The moving members are moved by rotation of a rotation member in a case where the rotation member is in contact with the moving members. In a case where a fixing member attached to the sheet storage device in place of the rotation member, movement of the moving members is regulated by placing the moving members into contact with the fixing member.

A medium transporting apparatus including a paddle that comes in contact with a medium discharged on a first tray including an upstream end matching member and that rotates to move the medium towards the upstream end matching member, and a low frictional resistance member configured to switch between an advanced state advanced from outside a medium mount region of the first tray to a first region, and a retracted state retracting from the first region to an outside of the medium mount region. The low frictional resistance member is, after a first medium is mounted on the first tray, switched from the retracted state to the advanced state, and is interposed between the first medium and a second medium when, after discharging the first medium, moving the second medium discharged from a pair of discharge rollers towards the upstream end matching member with the paddle.

The image forming apparatus may include a main body and a cassette to enter or exit the main body along a first direction to be mounted in or released from the main body, respectively. The cassette may include a supporter extendable in a second direction perpendicular to the first direction to protrude from an exterior of the main body. The main body may include a lever which is movable in the first direction between a supporting position at which the lever supports the main body and a release position at which to allow the cassette to enter or exit the main body along the first direction.

A feeding apparatus includes a stacking portion, a regulating portion, a moving portion, and a detection unit. The regulating portion abuts, in a width direction, one side of stacking portion sheets having different widths and regulates movement of the sheets in the width direction. The detection unit detects a position of the moving portion in an intersecting direction. The regulating portion includes an abut portion. By abutting or not abutting the abut portion, the moving portion moves to a first position and a second position. When the moving portion moves to the first position or the second position in a predetermined proceeding direction, the moving portion does not move from the first position or the second position while the regulating portion takes a position where the regulating portion further moves in the predetermined proceeding direction.

An image forming unit forms an image on a sheet. A sheet feed unit supplies the sheet to the image forming unit. A sheet tray is provided in the sheet feed unit. The sheet is placed on the sheet tray. An elevating plate is arranged on the sheet tray. The elevating plate can be ascended and descended between a descended position where the sheet is set and an ascending position higher than the descended position. A moving member can move between a first position in which the elevating plate is arranged in the descended position and a second position in which the elevating plate can move to the ascending position. A shielding member is interlocked with the ascending and descending operation of the elevating plate. The shielding member shields the moving member when the elevating plate is located at the descended position.
