Abstract
A photographic data recording mechanism in a camera includes a data illumination lamp, a first timing circuit actuated in response to the camera shutter release member for energizing the lamp for a set time interval and a second timing circuit also actuated in response to the shutter release member for applying a control signal subsequent to the lamp energizing time interval to a control circuit of shutter releasing electromagnet to release the shutter. The second timing circuit is adjustable to vary the time of application of the control signal and in an alternative structure the lamp energizing circuit may be disabled and the control signal applied is immediate response to the actuation of the release member. A single electromagnet may function to sequentially release the leading or trailing shutter members or separate electromagnets may be employed.
