Abstract

A sensor unit includes a first movable member including a member-to-be-detected, a sensor, and a second movable member. When a sheet is normally fed, the first movable member is in a first position, the member-to-be-detected is in a first phase, the second movable member is in a second position, and a functional/non-functional state of the member-to-be-detected is one state. When the sheet is not fed and the first movable member is in a second position, the member-to-be-detected is in the first phase, the second movable member is in a third position, and the functional/non-functional state is the other state. When the first movable member is in the first position and the second movable member is in a fourth position, by movement of the member-to-be-detected to a second phase, the functional/non-functional state is changed from the one state to the other state and an output of the sensor changes.
