Abstract
A control device for use in a camera for driving two electric motors has a simple circuit arrangement in which one of three serial circuits having series connected transistors is commonly used for selectively driving the two electric motors in turns. In addition, for driving electromagnets and motors, the control device includes a CPU for generating m bits control data and a decoder driver IC for decoding the n bits control data into a m bit signals which selectively drive the electromagnets and the motors, wherein n is smaller than m, so that the number of control signal lines needed for the transmission of the control data from the CPU to the decoder driver IC can be reduced.
