Abstract
A sheet processing apparatus includes a rotating member, a switching unit, and a pressing unit. The rotating member is rotatable and has a facing portion that faces a fold section of a sheet. The rotating member rotates so as to switch the facing portion to another facing portion. Each facing portion is provided with a protrusion. A set position of the protrusion in an axial direction varies from facing portion to facing portion. The switching unit rotates the rotating member so as to switch the facing portion that faces the fold section. The pressing unit presses the protrusion of the facing portion against the fold section.
Claims4
A sheet processing apparatus comprising:
- a rotating member that is rotatable and that comprises a facing portion that faces a fold section of a sheet,
- wherein the rotating member is configured to rotate so as to switch the facing portion to another facing portion, each facing portion being provided with a protrusion, and
- wherein a set position of the protrusion in an axial direction varies from facing portion to facing portion;
- a switching unit configured to rotate the rotating member so as to switch the facing portion that faces the fold section;
- a pressing unit configured to press the protrusion of the facing portion against the fold section;
- and
- an opposite member that comprises a protrusion and that is configured to be disposed opposite the rotating member,
- wherein the sheet processing apparatus is configured to nip the fold section between the protrusion of the rotating member and the protrusion of the opposite member.
A pair of rotating members configured to nip a fold section of a sheet from opposite sides and that are rotatable,
- wherein each rotating member comprises a facing portion configured to face the fold section of the sheet and to rotate so as to switch the facing portion to another facing portion,
- wherein in each rotating member, the facing portions are each provided with a protrusion, and wherein a set position of the protrusion in an axial direction of the rotating member varies from facing portion to facing portion,
- wherein a first protrusion serving as the protrusion provided in one of the pair of rotating members and a second protrusion serving as the protrusion provided in the other one of the pair of rotating members are configured to face each other with the fold section interposed therebetween, and
- wherein the first protrusion and the second protrusion are configured to nip the fold section.
