The present invention reduces chattering of a sensor flag at a home position and alleviates a collision noise of the sensor flag with a simple configuration. A sheet detecting apparatus includes a turning portion, a sensor outputting a detection signal in response to turning of the turning portion to the detecting position, a first sliding contact portion sliding in contact with the protruded portion so as to move relatively to the protruded portion in an axial direction of the turning portion when the turning portion returns from the detecting position to the home position, and a second sliding contact portion sliding in contact with the protruded portion so as to move relatively to the protruded portion in the axial direction of the turning portion when the turning portion turns from the home position to the detecting position.
