ABSTRACT:
A camera has an exposure device for effecting a photographing operation on a film in response to manipulation of a member, and a self-timer for causing the exposure device to effect the photographing operation after the counting of a predetermined time. The self-timer has a first state for causing the exposure device to effect the photographing operation only once and a second state for causing the exposure device to effect the photographing operation plural times. The camera comprises a first display for indicating that the self-timer is in an operable state, a second display for indicating that the exposure device functions plural times in response to the manipulation of the number, independently of the self-timer, and a control device for controlling the first and second display. The control device is adapted to only activate the first display in the first state of the self-timer and to activate both the first and second displays in the second state of the self-timer.
