Abstract

PURPOSE: To prevent breakage and other fault of gears in the transmission system, by enabling changeover to manual zoom from the transmission system through the clutch by moving the knob at the time of motor-driven zoom operation, in a cine camera having a constant current circuit in the motor-driven zoom system.
CONSTITUTION: At the time of motor-driven zoom operation, by moving left a knob 5 of a mode changeover operating member, a leaf spring contact 9 contacts with contact pieces 10aW10d, etc., and a gear 8a of a zoom cam ring 8 is driven through the gear transmission system 17 containing zoom motor M and clutch. By moving right the knob 5, the power source is opened, and a lever 11 is rotated clockwise around a fulcrum 12, and the pawl at the lower end separates the gear transmission system 17, so that the manipulation of manual zoom system 7 is enabled.
