A method for producing coreless roll paper includes a winding step in which paper 11 is wound on a shaft 20 in a roll shape, and an extracting step in which the shaft 20 is extracted from roll paper 12 to form a center hole 13. The shaft 20 includes a body part 22 having grooves 23, and a sleeve 30 is put on and fixed to the body part 22. In the winding step, the paper 11 is wound on the sleeve 30.

The present invention provides a sheet diverting unit for selectively diverting a sheet towards a first receiving path or a second receiving path, comprising an inlet path for advancing a sheet in a sheet supply direction towards a diverter; the diverter comprising a shaft, a deflector being connected to said shaft and extending between said shaft and a tip, and an actuator arranged for rotating the shaft thereby selectively pivoting the deflector between a first deflector position for directing the sheet into the first receiving path and a second deflector position for directing the sheet into the second receiving path; said deflector comprising a guiding edge and a second edge, said second edge arranged facing a second trajectory to the second receiving path in the second deflector position for directing the sheet into the second receiving path and said guiding edge arranged facing a straight first trajectory to the first receiving path thereby said guiding edge facing a guiding element in the first deflector position for guiding the sheet into the first receiving path; wherein the guiding edge comprises a recess portion, wherein the recess portion is arranged inwardly away from the straight first trajectory to the first receiving path when the deflector is arranged in the first deflector position, wherein the recess portion is arranged for extending substantially from the guiding element towards the shaft when the deflector is arranged in the second deflector position.

A paper feed roller of the present invention comprises a roller body 2 integrally formed of elastic material in a cylindrical shape in which a plurality of protruding lines 6 are disposed on a peripheral surface 5 at even intervals, wherein the roller body 2 is formed so that crest portions 6a and trough portions 6b are continuously provided in a circumferential direction, an opening angle is equal to or more than 2 and is equal to or less than 8, a radial height h of the protruding line is equal to or more than 0.051 mm and is equal to or less than 0.1 mm, and a curvature radius r1 at a shoulder is equal to or more than 0.55 mm.

A sheet transport apparatus according to an embodiment includes a roller having a surface formed from an elastic material. The roller transports a sheet. A rotation mechanism rotated the roller around an axis of the roller. A twist mechanism selectively twists the roller with respect to the axis. When the roller is twisted and the rotation mechanism rotates the roller, a sheet transported by the roller is transported in a first direction perpendicular to the axis and in a second direction parallel to the axis. When the roller is not twisted and the rotation mechanism rotates the roller, a sheet transported by the roller is transported in the first direction and not in the second direction.

A reject storage box is provided with a sufficiently thick cover body above a second storage space that stores banknote bundles W that a user has forgotten to take, and a guide space is provided penetrating the cover body in an oblique direction. In the reject storage box, when a banknote bundle falls into an intake hole from above, a lower face of the banknote bundle immediately contacts a position toward the top of a main guide face, and the banknote bundle W travels downward through the guide space with the lower face of the banknote bundle W sliding against the main guide face. The reject storage box thereby enables the banknote bundle dropping downward through the guide space to be maintained in a substantially uniform orientation, and ultimately enables the banknote bundle to be stacked neatly inside the second storage space.

A sheet feeder device includes: a sheet feed tray configured to store a sheet stack formed with a plurality of paper sheets; an elastic member capable of expanding and contracting; a contact mechanism configured to bring the elastic member into contact with an edge of the sheet stack; an expansion mechanism configured to expand the elastic member in a direction of stacking of the paper sheets; and a control unit configured to cause the expansion mechanism to expand the elastic member while the elastic member is kept in contact with the edge of the sheet stack by the contact mechanism.

A medium conveyance device includes a placement body having a bundle conveyance face on which a medium bundle is conveyed. A Scott-Russell body includes an abutting portion that abuts the medium bundle. A movement section causes the Scott-Russell body to abut against the medium bundle and moves the Scott-Russell body along the bundle conveyance face in first or second directions, so as to move the medium bundle along the bundle conveyance face in the direction. The conveyance state switching section switches to a first state in which the Scott-Russell body is caused to abut against a second direction side of the medium bundle and conveyance of the medium bundle toward the first direction is enabled, or to a second state in which the Scott-Russell body is caused to abut against a first direction side of the medium bundle and conveyance of the medium bundle toward the second direction is enabled.
