A sheet conveying apparatus for conveying a sheet in a conveying direction includes a pair of conveying rollers receiving and conveying a sheet; an endless conveying belt conveying the sheet; a plurality of balls to be rotatable in any direction while nipping the sheet with the conveying surface; a pair of regulating guides disposed on both sides of the conveying belt; a guide moving unit that moves the pair of regulating guides; and a roller moving unit that moves at least one of the pair of conveying rollers to a nip position and a nip release position. Before a rear end of the sheet passes the pair of conveying rollers, the pair of conveying rollers is moved to the nip release position by the roller moving unit, and then, the guide moving unit makes each of the pair of regulating guides reach the guide position from the retracting position.

The present invention is directed to providing to an align module of a medium deposition device which is capable of reducing a time to align a medium and improving reliability of medium alignment and allows a structure of a device for the medium alignment to be simplified. In the present invention, to implement the objectives, the align module is provided between a separating unit configured to separate media input to a bundle module into individual sheets and a recognition module configured to discriminate information and authenticity of a deposited medium and includes a transfer roller which transfers the media passing through the separating unit, a first driving unit which drives the transfer roller to be moved upward, an alignment roller configured to move a medium to an alignment surface to align one side end of the medium with the alignment surface in a state in which the transfer roller is moved upward by the driving of the first driving unit, and a second driving unit which drives the alignment roller to be rotated.

A paper conveyance device includes a roller, paper feed sensor, registration sensor, and controller. At a first time point at which specified time from start of draw of paper by the roller to arrival of the paper at the registration sensor has passed, when a detection result by the registration sensor is absence of the paper and a detection result by the paper feed sensor is presence of the paper, and the detection result by the paper feed sensor is the absence at a second time point at which standby time has passed from the first time point, the controller sets a safe paper feed mode in which the draw of the paper by the roller is started at a delay time point at which delay time has passed since a switching time point at which the detection result by the registration roller is switched from the presence to absence.

The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. In a sheet conveying apparatus that conveys a sheet using a conveying belt and balls, a sheet may be jammed and stopped on the conveying belt. In this case, it is difficult for a user to take out the sheet through a take-out port if the sheet is nipped by conveying roller pairs disposed upstream and downstream relative to the conveying belt in a sheet conveying direction. Thus, conveying roller pairs and the conveying belt are operated such that the sheet, which is stopped on the conveying belt and hence should be taken out through the take-out port, is brought into a state of being nipped only by the conveying belt and balls.

The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. Regulating guides are disposed on both sides of a conveying belt in a sheet width direction Y and can guide both end edges in the sheet width direction of a sheet S conveyed while being nipped by the conveying belt and the balls. A take-out port is provided on the side closer to the regulating guide in the sheet width direction Y, through which a sheet stopped on the conveying belt is taken out. A guide moving part moves the regulating guides. When a sheet is stopped on the conveying belt, the guide moving part moves the first and second regulating guides such that the regulating guide is retracted to a position at which a support surface does not support a first sheet end edge.

The invention which solves the relative speed problem between nips in a printing system is disclosed. The invention consists of a swing arm body that rotates about a pivot, an input drive gear, a forward swing arm gear, two reverse swing arm gears, a compound duplex drive gear, and a housing.

A sheet feeder includes a stacker, a sheet feeding member, an aligner, a switcher, a size specifying unit, and circuitry. The sheet feeding member contacts and feeds a sheet stack on the stacker. The aligner is movable to align a position in a sheet width direction of the sheet stack on the stacker. The switcher switches the aligner from a separation state to a contact state without waiting for a feeding start instruction after the sheet stack is stacked on the stacker. The circuitry delays a switching completion time when the size in the sheet width direction of the sheet stack specified by the size specifying unit is smaller than a given size, to be later than the switching completion time when the size in the sheet width direction of the sheet stack is equal to or greater than the given size.

To provide a printing apparatus and a conveyance apparatus that are capable of preventing a cut position to be cut by a cutting unit from deviating, in a printing apparatus in which printing is performed by a printing unit on a printing medium that is conveyed by a conveyance unit and the printing medium is cut by a cutting unit while being conveyed by the conveyance unit and a conveying force apply unit, the conveying force apply unit is arranged on an outer side relative to the cutting unit and configured to apply a conveying force to the printing medium in a direction outward in a width direction from an upstream to a downstream in a conveyance direction.

To correct a posture of a paper sheet inserted from various positions and angles to a normal transport state without causing any deformation due to contact with a side wall while transporting the paper sheet continuously and non-intermittently. A drive-side unit (20) includes at least one drive roller (25) that is supported rotatably about a shaft orthogonal to a normal paper-sheet transport direction and axially movably, an elastic biasing member (40) that elastically biases the drive roller in an axial direction, and a cam mechanism (50) that transmits a driving force from a driving source to the drive roller, and operates when an external force exceeding a predetermined value in a direction other than a normal transport direction is applied to the paper sheet transported by the drive roller, so as to change an axial position of the drive roller against an elastic biasing force, and a driven-side unit (100) includes a driven roller that changes a transport grip between the drive roller and a paper sheet according to a change of an axial position of the drive roller.

A roller for guiding a sheet (101) by friction has a contact surface (2) designed to be in contact with the sheet (101), the contact surface (2) having, overall, a shape of revolution when the roller (1) is at rest, a central portion (6) configured to mechanically connect the roller (1) to a rotating drive element, and a deformation portion (10) located between the contact surface (2) and the central portion (6), the deformation portion (10) being configured to deform elastically when the roller (1) guides the sheet (101) by friction.

The deformation portion (10) comprises at least one cut (12) extending from the contact surface (2) to the central portion (6), the cut (12) being arranged such that the deformation portion (10) comprises at least one elastically deformable segment (16).
