段とで構成したことを特徴とするカメラにおける
移動鏡胴駆動装置。 In a moving lens barrel drive device for a camera that drives a moving lens barrel slidably supported within a lens barrel frame to a first position and a second position in a direction along an optical axis by a motor, the moving lens a position detecting means for detecting that the cylinder is located inwardly of each of the first position and the second position; an opening/closing means for intermittent energization of the motor; After receiving the output, the motor is energized intermittently from the time the output is received, and each time a predetermined unit time elapses from the time point, the time during which the energization is applied within the predetermined unit time is decreased. A movable lens barrel drive device for a camera, comprising a control means for controlling the opening/closing means to cut off the current supply.
