Abstract
An accessory apparatus for producing visible information on a film in a moving picture camera by exposure of the film through optical indicating elements comprises an actuating circuit arrangement for the optical indicating elements. The circuit arrangement includes a driving circuit for actuating the indicating elements and a control circuit associated with the driving circuit. The driving circuit is responsive to the control circuit and the control circuit is controllable in response to the picture frequency of the camera. It comprises an electrical signal transmitting stage, a signal recording stage connected to the transmitting state and directly receiving the signal therefrom, the driving circuit and the signal transmitting stage being energizable simultaneously, and a blocking circuit stage de-energizing the control circuit after passage of a pre-selectable number of picture frames after the standard picture frequency has been reached.
