  • Patent number: 4051500
    Abstract: A photographic camera has a shutter and a shutter setting and releasing mechanism which includes an operating member which moves in a predetermined path and direction when released. The camera further includes a time-delay mechanism for the shutter which is arrested by an arresting member when the latter is in its resting position. A coupling element selectively pivots between two positions in one of which it is located outside the path of movement of the operating member while in the other position it engages both the operating member and the arresting member. The coupling component is also mounted for movement in the direction of movement of the operating member when in engagement therewith so that it displaces the arresting member out of the arresting position whereby the time-delay mechanism is released.
