A camera includes a flash mechanism, an exposure-preparatory operation mechanism, a motor, a clutch mechanism arranged to transmit an output of the motor to the flash mechanism during the time of operation of the motor in a first direction and to transmit the output to the exposure-preparatory operation mechanism during the time of operation of the motor in a second direction, a first detecting device for detecting an operational state of the flash mechanism, a second detecting device for detecting an operational state of the exposure-preparatory operation mechanism, and a controller for controlling driving of the motor in response to outputs from the first and second detecting devices.
