PURPOSE:To recharge only an auto-focusing mechanism in the focus lock mode, by operating externally a switching member which stops charging of the auto- focusing mechanism at the end of charging. CONSTITUTION:The auto-focusing is performed in accordance with the movement of a range adjusting lever 21 charged by a spring 27 through a pawl 25a controlled by a magnet 28 which is interlocked with the shutter release to be excited and is returned to nonexcitation by a focus signal. When a reset lever 20 is operated externally under this state, connections of contacts S1 and S2 are opened at the end of charging of the lever 21 due to the spring 27, and the power supply to a motor is cut off, and a switching member 32 which stops charging is turned clockwise to release the detention of a cam 30, and contacts S1 and S2 are connected again to turn the motor, and the lever 21 is charged again by the spring 27 through a notched gear 29, a rack 31, etc. As the result, a waste of the film and etc. due to the failure of range finding or the like is prevented. |
