SHEET CONVEYANCE APPARATUS AND IMAGE FORMING APPARATUS

摘要

A sheet conveyance apparatus is equipped with a first rotator, a second rotator conveying a sheet together with the first rotator, a cam member changing a position of the second rotator with respect to the first rotator, a drive unit rotating the cam member, and a load portion applying load on a rotation of the cam member. The load portion includes a contact member having a cam surface formed on a side surface in an axial direction of the cam member, an abutment member capable of abutting against the cam surface, and a biasing member biasing one of the contact member and the abutment member toward the other, a biasing force of the biasing member converted into a force, applying load to the rotating cam member, by the cam surface opposing to a rotating direction in which the cam member is driven by the drive unit.

主权项

1. A sheet conveyance apparatus comprising:
a first rotator; a second rotator conveying a sheet together with the first rotator; a cam member changing a position of the second rotator with respect to the first rotator; a drive unit rotating the cam member; and a load portion applying load on a rotation of the cam member; the load portion including:
a contact member having a cam surface formed on a side surface intersecting a line extending in an axial direction of the cam member;an abutment member capable of abutting against the cam surface; anda biasing member biasing one of the contact member and the abutment member toward the other such that the cam surface of the contact member and the abutment member come into contact each other, wherein a biasing force of the biasing member is converted into a force, applying load to the rotating cam member, by the cam surface opposing to a rotating direction in which the cam member is driven by the drive unit.
