摘要： A follow roller nips a sheet with a discharge roller. The follow roller is harder than the discharge roller. A paddle is rotatable together with the follow roller. The paddle includes protrusions and recesses arranged alternately in a circumferential direction of an axis of the follow roller. Each of the protrusions protrudes farther radially outward than an outer circumference of the follow roller to contact the sheet. Each of the recesses is recessed radially inward between two of the protrusions adjacent to each other in the circumferential direction. A groove is located between the follow roller and the paddle in a width direction parallel to a direction in which the axis extends. The groove is located at a same position as an end of the discharge roller in the width direction. The groove is recessed one round farther radially inward than the outer circumference of the follow roller.

摘要： A feeding unit includes a retard roller, a first holder, a second holder, an accommodating portion, a pressing portion, a second pressing portion, a release lever, and a second restricting portion. The accommodating portion accommodates the second holder. The second pressing portion presses the second holder in a +Z direction. The release lever restricts the movement of the second holder in the +Z direction. The second holder is provided with a plurality of restricted portions in a Y direction and a +A direction, respectively. The second restricting portion restricts the movement of the second holder in a −Z direction. The second restricting portion has a restricting surface. The restricting surface is provided in the accommodating portion and is configured to come into contact with the plurality of restricted portions.

摘要： A conveying device includes a rotating member having sharp teeth and configured to rotate while being in contact with an object that is being conveyed, and a holder configured to support the rotating member. When seen from a downstream side in a direction of sheet conveyance, the rotating member is rotatably supported by the holder such that the rotating member is allowed to incline toward one side but is prevented from inclining toward an opposite side. The teeth of the rotating member each have an asymmetrical shape with the one side thereof sloping.

摘要： A sheet conveying device includes a driving roller, a driven roller and a pair of bearing members. The pair of bearing members is configured to rotatably support both ends of a rotating shaft of the driven roller. The bearing member has a supporting part and a pressing part. The supporting part is formed by winding an end portion on one side of a wire rod in a spiral shape. The supporting part has a shaft hole through which one end of the rotating shaft can be inserted. The pressing part is formed by winding an end portion on the other side of the wire rod in a spiral shape in an orthogonal direction to the rotating shaft. The pressing part is disposed so as to press the supporting part in a direction in which the driven roller comes into pressure contact with the outer face of the driving roller.
