ABSTRACT:
A rotary clutch device includes: a tooth-partially-lacking gear that can mesh with a drive gear and is given initial rotation force; a rotatable cam body that is concentric with the tooth-partially-lacking gear, having an engagement step; and an elastic body. An engagement lever is engaged with and disengaged from the engagement step according to an intermittent operation of an actuator so that the tooth-partially-lacking gear starts and stops to rotate. Rotation force of the tooth-partially-lacking gear is transmitted to the cam body via the elastic body.
