An interconnection mechanism for a zoom camera having a zoom finder and a zoom flash is comprised of a finder zooming cam rotating in cooperation with a zoom lens, and a flash angle changing cam rotating in cooperation with the finder zooming cam. The finder zooming cam has at least a helicoid cam surface and a rotational axis extending in parallel to a moving path of a movable lens element of the zoom finder. The flash angle changing cam has at least a helicoid cam surface and a rotational axis extending in parallel to the rotational axis of the finder zooming cam. The flash angle changing cam is disposed adjacent to the finder zooming cam, and rotates with the finder zooming cam through gears. These cams are disposed between the zoom finder and the zoom flash. A cam follower pin provided on a lens frame of the movable lens is engaged with the helicoid cam surface of the finder zooming cam such that the movable lens element moves along the moving path in response to rotation of the finder zooming cam, thereby changing the magnification of the zoom finder. A pair of cam follower claws provided on a flash projecting portion of the zoom flash are engaged with the helicoid cam surface of the flash angle changing cam such that the flash angle projecting portion moves in the direction of the rotational axes in response to rotation of the flash angle changing cam, thereby changing the projection angle of flash light.
An interconnection mechanism for a zoom camera having a zoom finder and a flash device, said zoom finder having at least a movable lens element movable to change magnification of said zoom finder in correspondence with magnification of a zoom lens, said flash device having a flash projecting portion movable to change projection angle of light projected from said flash device in accordance with angle of said zoom lens, said interconnection mechanism comprising:
