A sheet separation device includes a rotator, a nipping member to nip the two-ply sheet with the rotator, a first conveyor to convey the two-ply sheet in a first direction toward the rotator and a second direction reverse thereto, a winding member to wind the two-ply sheet around the rotator, a second conveyor to convey a sheet medium in the second direction, a separation claw to move in a width direction; a sheet guide to guide the separated two sheets to different passages; and control circuitry. The first conveyor conveys the two-ply sheet to the rotator with a bonded portion at an upstream end. The control circuitry inserts the separation claw into a space between the two sheets, adjusts a projection amount of the two-ply sheet from a nip of the first conveyor in the second direction, and inserts the sheet medium in two-ply sheet adjusted in the projection amount.

A document feeder includes a device body, and an opening and closing cover which is provided to be openable and closable with respect to the device body, and including a paper feed roller and a paper feed roller drive shaft on the device body. The document feeder includes a guide member, which is mounted rotatably to the paper feed roller drive shaft on an outer side of the paper feed roller in a roller axis direction thereof. The guide member guides a document being conveyed, in a state where the opening and closing cover is closed, by being opposed to the paper feed roller drive shaft in a predetermined orientation.

An infeed alignment device (10) for aligning a carton blank (14) such that a picking device can pick the carton blank. The infeed alignment device comprises an upper alignment member (11) for pushing on an upper part of the carton blank, a lower alignment member (12) for pushing on a lower part of the carton blank, and wherein the upper and/or lower alignment member is configured to push in a push direction on the top and/or the bottom of the carton blank such that the carton blank is in a picking position for the picking device.

A sheet feeding apparatus includes a sheet supporting portion configured to support a sheet, a feed rotary member configured to feed the sheet supported by the sheet supporting portion, a curved conveyance path through which the sheet fed by the feed rotary member passes and which is curved upward, an upper conveyance path disposed above the sheet supporting portion so as to pass through a sheet and configured to join with the curved conveyance path, and a driven rotary member disposed inside of the curved conveyance path in a curved direction thereof and driven to rotate by the sheet passing though the curved conveyance path.

According to an embodiment, a sheet feeding mechanism includes a first elastic body. The first elastic body blocks a first reference line and a second reference line. The first elastic body has a first angle formed between the first elastic body and the first reference line, the first angle being an acute angle. The first reference line is a reference line along a take-out direction by the first roller. The second reference line is a reference line connecting a nip between the second roller and the third roller and a contact position of the first roller and a sheet.

Provided is a sheet storage apparatus including: an apparatus body; a sheet storage section; a top cover; a sheet feeding section; a restricting cursor; a blowing device; a sheet holding-down member; and a moving mechanism. The sheet storage section includes a sheet supply port, and a sheet stacking portion. The top cover is pivotable to an opening position and to a closing position. The blowing device includes a fan and a vent. The sheet holding-down member includes a restricting piece. The moving mechanism is coupled to the sheet holding-down member, moves the sheet holding-down member to a restricting position by coming into contact with the top cover under a state in which the top cover has come to the closing position, and moves the sheet holding-down member to a retracted position by separating from the top cover when the top cover is moved to the opening position.
