ABSTRACT:
The disclosed camera is capable of being operated either with a normal shutter release or a remote cable release. An exposure control circuit includes a photoelectric element for automatically controlling the exposure on the basis of the brightness of the object being photographed. A motor control circuit operates a photographic mechanism. A first switch operates in response of the first step of depression of a release button and a second switch responds to further depression of the release button. A third switch is connected to the remote release in parallel with the second switch for actuating the automatic exposure control circuit and the motor control circuit. A delay circuit starts in response to operation of either the first or third switches and produces a signal at a predetermind time after operation of either of the switches. Inhibiting means respond to the signal from the delay circuit to inhibit operation of the motor control circuit until the delay circuit produces its signal so that the automatic exposure control circuit can complete its operation whether it is actuated by the shutter release button on the camera or remotely.
