A medium placement device includes a placement unit configured to have cut single paper thereon, a cover member configured to have single paper supplied to or discharged from an opening portion thereon, and a movement unit configured to move the cover member between a first position and a second position that is lower than the first position.

A sheet conveying device includes: a tray; a roller; a roller arm; a lever; and a dust proof cover including: a first cover, a second cover, and a pressure piece. The roller arm is movable between an abutment position where the roller abuts on the tray and a separation position where the roller is away from the tray. The second cover is movable between a first position in proximity to the tray and a second position away from the tray. The pressure piece is away from the lever to permit the roller to be positioned in the abutment position when the second cover is in the first position, and presses the lever to move the roller to the separation position when the second cover is in the second position.

A tape feeding apparatus includes a supply unit that supplies a release paper and a tape attached to the release paper, a blade unit that separates the release paper and the tape, having a triangular pillar shape extending in a first direction, and including a first surface, a second surface directed perpendicular to the first surface and contacting the release paper, and a third surface in contact with the first surface and the second surface to form a sloped surface, and an lighting unit attached to the first surface.

A paper sheet storage device includes a supply reel that supplies a rolled tape; a winding drum around which a banknote is wound together with the tape supplied from the supply reel; a first detection unit that detects a supply amount of the tape supplied from the supply reel; and a second detection unit that detects the winding drum of which the outer diameter becomes equal to or larger than a predetermined outer diameter when the banknote is wound around the winding drum together with the tape.

A sheet processing apparatus that is capable of facilitating a process by eliminating waste of a result even if a translucent sheet is conveyed. A conveyance unit conveys a sheet received from an image forming apparatus. An optical sensor detects a sheet end conveyed. An alignment unit aligns sheets based on information detected by the optical sensor. A post-process unit performs a post-process to the sheets aligned. An input unit inputs sheet information about a type of the sheet to be received from the image forming apparatus. A control unit stops sheet conveyance when the sheet information indicates a first type sheet and when the optical sensor cannot detect the sheet end, and continues sheet conveyance when the sheet information indicates a second type sheet of which transmittance is higher than the first type sheet and when the optical sensor cannot detect the sheet end.
