A sheet conveying device includes a blocking member having a blocking surface with which a leading end of a sheet that is being conveyed comes into contact for obliquity correction. The blocking member is rotated by being pushed by the sheet against an urging force of a positioning unit that positions the blocking member to be in the standby position. The blocking member is rotatable to be in a sheet-passage-allowing orientation in which the sheet is allowed to pass. When a trailing end of the sheet that is being conveyed has passed the blocking member, the blocking member that is in the sheet-passage-allowing orientation rotates in a same direction as a sheet conveyance direction and is positioned to be in a standby position.

A recording device includes a recoding unit, a discharge rollerunit, a medium receiving tray, a motor serving as a power source of the discharge roller, a power transmission unitunit that is configured to switch between a power transmission state in which power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray, and a restriction unitunit that is configured to switch between a restriction state in which the restriction unit restricts displacement of the medium receiving tray when the power transmission unit is in the power non-transmission state, and a non-restriction state in which the the restriction unit does not restrict the displacement of the medium receiving tray when the power transmission unit is in the power transmission state. 1. A recording device , comprising:a recording unit that is configured to perform recording on a medium;a discharge roller that is configured to discharge the medium on which recording was performed by the recording unit;a medium receiving tray that is configured to receive the medium discharged by the discharge roller and switch between a first state and a second state in which the medium receiving tray is displaced in a discharge direction of the medium with respect to the first state;a motor that serves as a power source of the discharge roller and the medium receiving tray;a power transmission unit that is configured to switch between a power transmission state in which power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray; anda restriction unit that is configured to switch between a restriction state in which the restriction unit restricts displacement of the medium receiving tray when the power transmission unit is in the ...

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus is configured to upgrade an installed corrugated board processing machine (e.g., ) and includes a feed table surface for boards (e.g., ) having drive wheels (W, W, W) in an initial variable velocity zone which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder also includes a controller configured to receive predetermined velocity signals from the host machine and generate (i) a first initial variable velocity control signal for initial variable velocity zone and (ii) a second velocity control signal for second velocity zone in response.

An image forming apparatus including a housing, a sheet cassette, a second roller, a gear train, a pendulum gear, and a stop member. The gear train includes a gear rotatable together with the second roller. The pendulum gear is movable between a meshing position where the pendulum gear is in meshing engagement with the gear train and a separated position where the pendulum gear is separated away from the gear train. The stop member allows the pendulum gear to move from the separated position to the meshing position. In the state where the sheet cassette is at an internal position and the stop member is at the second position, the stop member is out of contact with a part of the sheet cassette in a first direction but contacts the part of the sheet cassette in a second direction.
