Time-sharing drive apparatus for motor of camera

摘要

A time-sharing drive apparatus for a camera having a plurality of motors includes a motor drive control system which alternately drives the motors in a time-sharing control. When the camera includes a zoom lens provided with a first stationary lens group, a second movable lens group and a third movable lens group, the motors are composed of a first motor which opens and closes a diaphragm of the zoom lens, a second motor which moves the second lens group, and a third motor which drives the third lens group. The motor drive control system which drives the first, second and third motors is controlled via a time-sharing system.
