Dual film exposure, electronic exposure camera with delay in film rewind after final exposure to allow film rewrite

摘要

A camera for exposing latent images on successive frames of a filmstrip having magnetic recording capacity, includes a memory that stores a count indicative of the film frames remaining to be exposed (including a count of “0” to indicate that the final frame was exposed), a magnetic head that magnetically records user-selected information on the filmstrip adjacent each film frame, and a motor that is actuated following exposure of each film frame to advance the filmstrip forward one frame increment to permit the magnetic head to record the information on the filmstrip adjacent each exposed frame and that is actuated after the magnetic information is written on the filmstrip adjacent the final exposed frame to rewind the exposed film length rearward. An input receiving control is connected to the memory, the magnetic head, and the motor for delaying actuation of the motor to rewind the exposed film length rearward after the magnetic head has magnetically written the information on the filmstrip adjacent the final exposed frame, to give the user some time to manually input to the control that the information magnetically written adjacent the final exposed frame should be rewritten, and in the absence of the input by the time the delay has elapsed triggers actuation of the motor to rewind the exposed film length rearward.
