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.

Provided is a printing apparatus comprising: a discharging unit configured to convey and discharge print media; a tray configured to receive print media discharged in a first direction from the discharging unit; and a drive unit configured to move the tray in a second direction perpendicular to the first direction. In discharging print media, the tray is moved in the second direction to thereby receive the discharged print media at a plurality of different positions on the tray. The tray is movable to a take-out position being a position closer in the second direction to a take-out side where print media are taken out than any of the positions at which the tray receives the print media discharged from the discharging unit.

A printing apparatus can prevent a print medium from buckling during discharging. In a case in which the print conveyance speed determined by the print mode is higher than or equal to a specified speed, the print medium after printing is conveyed to a discharging tray at the print conveyance speed, and in a case in which the print conveyance speed determined by the print mode is lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

A paper sheet storage device includes a supply reel which has a constant load spring formed of a metal band and around which the metal band is rolled, and a winding drum around which banknotes are wound together with the metal band supplied from the supply reel.

A document conveyance apparatus includes a loading portion having a loading surface for a document, a rotating member, a detection unit, a feeding roller, and a support portion. The rotating member includes a front end portion protruding from the loading surface and rotates about a rotary shaft by being in contact with the loaded document. The detection unit detects rotation of the rotating member and detects presence or absence of the loaded document. The feeding roller feeds the document by being in contact with the document loaded on the loading surface. The support portion rotatably supports the rotary shaft. When the rotary shaft is viewed from an axial direction, the rotary shaft includes a recessed portion recessed from an outer periphery section of the rotary shaft toward a shaft center of the rotary shaft. The support portion is in contact with the recessed portion to rotatably support the rotating member.

A stacked-sheet detection device includes a main shaft portion, a first detection arm portion, a parallel shaft portion, a second detection arm portion, an interlocking arm portion, a detected portion, and a detection sensor. The second detection arm portion is provided outside a first passing range, rotates in a predefined rotation direction and causes the interlocking arm portion to rotate in the predefined rotation direction by contacting a sheet that passes through a second passing range. When at least one of the first detection arm portion and the interlocking arm portion rotates in the predefined rotation direction, the main shaft portion rotates in the predefined rotation direction, and the detected portion rotates in the predefined rotation direction.

A sheet feed cassette monitor includes an actuator with another end portion, a detecting circuit, a plurality of protrusions, a signal monitoring circuit, and a signal determining circuit. When the one end portion is in contact with a paper sheet, the other end portion swings in a first direction. When the one end portion is not in contact with the paper sheet, the other end portion swings in a second direction opposite direction to the first direction. The detecting circuit detects the swinging of the other end portion on the actuator. The plurality of protrusions are convexly installed in an asymmetric manner with respect to a putting-in/taking-out direction of the feed cassette. The signal determining circuit determines a presence/absence state of the paper sheet housed in the sheet feed cassette and an open/close state of the sheet feed cassette based on a pattern of change in the monitored signal.

A sheet detecting apparatus including: a detection unit including a lever member having an abutment surface abutting a conveying sheet and a holding member configured to hold the lever member, the detection unit moved by the lever member pushed by the sheet; a first urging portion configured to urge the holding member to a waiting position after the sheet is separated from the abutment surface; a support portion configured to support the lever member movable with respect to the holding member to move the lever member to a retracted position for allowing the sheet to pass the lever member contacting a surface of the sheet when the holding member is in the waiting position; and a second urging portion configured to urge the lever member so that the lever member is moved from the retracted position to a position in which the abutment surface abuts a succeeding sheet.

A sheet transportation device includes a sheet loading table, a feeding unit that feeds a sheet placed on the sheet loading table, a first detection unit that is provided downstream of the feeding unit in a sheet transportation direction and that detects a position of a leading end of the sheet, a second detection unit that is provided upstream of the feeding unit in the sheet transportation direction and that detects a position of a leading end of a small-size sheet which is smaller than the sheet detected by the first detection unit, and a control unit that starts feeding the sheet based on a result of detection performed by any of the first detection unit or the second detection unit in accordance with a size of the sheet.

A sheet detecting apparatus which detects a sheet conveyed while being nipped by a pair of fixing rollers includes: an abutting portion which is supported so as to be rotatable about a rotation shaft and against which the sheet abuts; and a photo sensor which detects the rotation of the abutting portion, wherein the rotation shaft is disposed at a predetermined inclination angle so that the rotation shaft is not parallel to a sheet surface of the sheet against which the abutting portion abuts.
