A control device for an automatic camera is provided for controlling a number of electromechanical mechanisms in the camera. A microcomputer can control these mechanisms through output ports of a lesser number than the number of mechanisms to be controlled. A decoder can respond to this outputted data to provide appropriate control of the respective electromechanical mechanisms.

A control device for use in a camera, comprising: first number m of electromechanical converting means for driving mechanisms of the camera, the first number being greater than one; a microcomputer for carrying out an exposure calculation operation and a sequence control of the camera exposure and having a second number n, which is less than the first number m, of output ports, said microcomputer sequentially determining, with the progress of the sequence control, one of the mechanisms of the camera and outputting from the output ports n bits of control data to cause the corresponding electromechanical converting means to operate, the n bits of control data being a specified code data when no mechanism is necessary to be driven, and a decoder driver IC to which the first number m of the electromechanical converting means are connected through m number of output signal lines, and which decodes the n bits of control data and selectively drives, based on the decoded data, one of the corresponding electromechanical converting means with the decoded data representing one of the mechanisms to be driven and none of the electromechanical converting means with the decoded data being the specified data.
