ABSTRACT:
A self-timer device for a camera in which the set lever of an electronic self-timer device may be automatically restored and in which, even if the self-timer device has been set, it can be reset so that it is possible to perform an ordinary photographing operation. The device includes a self-timer set lever and a first cam rigidly coupled thereto with a bent portion standing away from the set lever and abutting a cam surface of a second cam member. The second cam member, upon being released by activation of a release button, is rotatable by the self-timer set lever through the bent portion of the first cam member rotating until it is locked in position by a locking lever. An operating member is provided which is activatable by a release lever which upon activation releases the second cam member. The bent portion of the first cam member also abuts a control switch of the electronic control circuit including an electrical delay circuit for providing a preferred delay time.
