Abstract: PURPOSE:To move a lens barrel from a photographic position to a next photographic position after photographing by rotating stepwise a distance ring which has a cam surface for controlling the extension extent of the lens barrel and moving the lens barrel to its focusing position. CONSTITUTION:The coil 21 of a rotor 19 is powered on once and the rotor 19 rotates to extrude a driving lever 12 with the pin 20a at the tip part 20, rotating the distance ring 5 counterclockwise by one tooth of a partial ratchet 5c.
