Auxiliary drive system for running-in movable components

摘要

An auxiliary drive system controls an actuator to force movable members such as shutter blades of a power-driven shutter system to cause predetermined movement so as thereby to run in the movable members when the the power-driven apparatus is loaded with a battery as a power source, when the power-driven apparatus is powered on or when a predetermined time has passed since the last operation of the movable members.
