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 paper guide mechanism that facilitates operation without easily allowing deviation of a wide guide unit. In a paper guide mechanism (10), a position-holding member (13) holds the widthwise position of a widthwise moving member (12) by bringing a first fixing-side locking section (11e) and a first moving-side locking section (13d) into contact with each other on a surface perpendicular to a direction of movement of the widthwise moving member (12) even in a case in which the widthwise moving member (12) is about to move in any direction along the width direction. The position-holding member (13) has a movement-restricting section (13e). The movement-restricting section (13e) restricts the movement of the position-holding member (13) in an orientation in which the first fixing-side locking section (11e) and the first moving-side locking section (13d) are moved away from each other by bringing the position-holding member (13) into contact with a second surface of a supporting member (11) on a side opposite to a first surface.

A sheet conveying apparatus includes: a first pair of conveying rollers for conveying a sheet; a second pair of conveying rollers against which the leading edge of the sheet conveyed by the first pair of conveying rollers is hit and which conveys the sheet together with the first pair of conveying rollers by rotating after a loop is formed on the sheet; a separating portion for separating the first pair of conveying rollers; a first conveyance path for guiding the sheet; a second conveyance path which is a path different from the first conveyance path and guides the sheet; and a controller which changes a separation timing at which the first pair of conveying rollers is separated after the loop is formed on the sheet, depending on whether the sheet is guided by the first conveyance path or by the second conveyance path.

A printing apparatus includes a print section configured to perform printing on a first side of a medium and then perform printing on a second side that is a back side of the first side, a supply path configured to supply the medium toward the print section, a feeding roller configured to feed the medium along the supply path from an upstream side to a downstream side in a transport direction, a toothed roller provided on the downstream side of the feeding rollers in the transport direction, a drive source configured to rotate the feeding roller and the toothed roller, and a controller configured to control driving of the drive source. The controller performs rotation control for rotating the feed rollers prior to the rotation of the toothed roller with which the medium has collided.

A transport device includes a transport member that transports a recording medium while adjusting a leading end of the recording medium, and a guide member that is disposed upstream from the transport member in a transport direction of the transport member to guide the recording medium to the transport member along a transport path, the guide member being rotatable in a direction to open the transport path while having a downstream portion in the transport direction of the transport member serving as an axis.

A sheet skew feed correcting apparatus is provided which includes: a driving rotation member that is driven to rotate; a first driven rotation member that is pressure contacted against the driving rotation member; a first holder rotatably holding the first driven rotation member; a second driven rotation member that is pressure contacted against the driving rotation member; a second holder rotatably holding the second driven rotation member; and a shutter portion with which a leading end of a sheet comes into contact for skew feed correction, the shutter portion moving pivotally with one end portion thereof supported by the first holder and another end portion thereof supported by the second holder; wherein the shutter portion has abutting portions with which the leading end comes into contact, and a coupling portion extending so as to couple the abutting portions together between the first and the second driven rotation members.

A sheet conveyance device (1) includes a feed tray (20), a feeding unit (50), a stopper (30), a first abutted portion (41), and an impact reducing mechanism (10). Sheets are loaded on the feed tray (20). The feeding unit (50) feeds the sheets. The stopper (30) is rotatably supported on the feeding unit (50) and rotates when pressed by the sheets inserted into the feed tray (20). The stopper (30) comes into contact with the first abutted portion (41) in association with the rotation of the stopper (30). The impact reducing mechanism (10) reduces impact applied to the first abutted portion (41) by the stopper (30).

The present sheet conveying apparatus includes: a resist roller pair that corrects skew of a sheet conveyed from a sheet supplying unit; and a guide portion disposed at an upstream side relative to the resist roller pair in a sheet conveying direction, the guide portion including a first guide and a second guide disposed opposite to the first guide with a sheet conveying path therebetween, the second guide being located at a projection side of a curved portion formed in the sheet when a tip of the sheet is conveyed to a nip portion of the resist roller pair that is stopped, the second guide being divided into a plurality of divided guides in an axial direction of the resist roller pair, a flexible film being disposed to cover at least a portion of a space between the plurality of divided guides.

A sheet positioning member is provided on a sheet placing surface in such a way as to be movable in a predetermined first direction. The sheet positioning member includes a moving body, an abutting portion, an operation member, and a cam portion. The moving body moves in the first direction on the sheet placing surface. The abutting portion has an abutting surface that abuts on the side end portion when the sheet positioning member positions the sheet. The operation member is supported by the moving body so as to be pivotable around a support shaft that extends in the first direction, on a side of a back surface of the abutting portion. The cam portion displaces the abutting portion toward the side end portion by being pressed by the operation member in response to a pivoting operation of the operation member.

A sheet conveying apparatus includes a pair of first conveying rollers, a pair of second conveying rollers provided at a downstream of the pair of first conveying rollers in a conveying direction of a sheet, a loop being formed in the sheet when a head of the sheet conveyed by the pair of first conveying rollers butts against the pair of second conveying rollers, and a controller which executes a first control mode in which the sheet is conveyed by the pair of first conveying rollers and the pair of second conveying rollers without dissolving the loop formed in the sheet, or a second control mode in which the loop formed in the sheet is dissolved, and the sheet nipped by the pair of first conveying rollers and the pair of second conveying rollers is conveyed.
