Abstract
A transport unit transports a transport medium after the transport medium is newly placed as an uppermost medium in a state in which one or a plurality of placed media are already placed in a processing tray. At this state, at least one of the placed media placed on the processing tray is pressed by a pressing unit at a pressing position. After the transport unit is separated away from the transport medium, the pressing unit can move from the pressing position to a retraction position.
Claims12
A post-processing device comprising:
- a processing tray configured to place a medium after recording thereon;
- a transport unit configured to transport, in a transport direction, an upper most medium placed on the processing tray by contacting with an upper surface of the upper most medium placed on the processing tray;
- an alignment unit configured to align a downstream end, in the transport direction, of the medium placed on the processing tray;
- a pressing unit configured to press, against the processing tray, the medium placed on the processing tray;
- and
- a control unit configured to control an operation of the pressing unit, wherein
- the pressing unit is configured to move between a pressing position at which the medium placed on the processing tray is pressed and a retraction position at which pressing on the medium placed on the processing tray is released,
- the control unit is configured to, when the transport unit transports a transport medium after the transport medium is newly placed as an uppermost medium in a state in which one or a plurality of placed media are already placed on the processing tray, cause the pressing unit at the pressing position to press at least one of the placed media placed on the processing tray,
- the control unit is configured to perform switching between first control and second control, when the transport unit transports the transport medium after the transport medium is newly placed as the uppermost medium in the state in which the one or plurality of placed media are already placed on the processing tray,
- the first control being for moving the pressing unit from the pressing position to the retraction position after the transport unit is separated from a transport medium, and
- the second control being for moving the pressing unit from the pressing position to the retraction position before the transport unit is separated from the transport medium or when the transport unit is separated from the transport medium.

- the pressing unit is configured to move between a pressing position at which the medium placed on the processing tray is pressed and a retraction position at which pressing on the medium placed on the processing tray is released,
- the control unit is configured to, when the transport unit transports a transport medium after the transport medium is newly placed as an uppermost medium in a state in which one or a plurality of placed media are already placed on the processing tray, cause the pressing unit at the pressing position to press at least one of the placed media placed on the processing tray,
- the control unit is configured to, after the transport unit is separated away from the transport medium, move the pressing unit from the pressing position to the retraction position,
- the pressing unit is a member having a friction coefficient smaller than a friction coefficient of the medium placed on the processing tray, and
- the pressing unit has a first surface and a second surface,
- the first surface has a friction coefficient greater than a friction coefficient of the second surface, and
- when the transport unit transports the transport medium after the transport medium is newly placed as the uppermost medium in the state in which the one or plurality of placed media are already placed on the processing tray, the pressing unit at the pressing position is brought into contact, at the first surface, with the uppermost placed medium placed on the processing tray and is brought into contact, at the second surface, with the transport medium.
