Abstract
A power transmission mechanism includes a rotational drive member which rotates to drive a driven member, a drive switcher for switching between a transmission-ON state in which a driving force of a drive source is transmitted to the rotational drive member to rotate the rotational drive member and a transmission-OFF state in which the transmission of the driving force to the rotational drive member is canceled, and a rotation restrictor which allows the rotational drive member to rotate when the drive switcher is in the transmission-ON state and is engaged with the rotational drive member to restrict rotation of the rotational drive member when the drive switcher is in the transmission-OFF state.
