ABSTRACT:
A recording projector for sound motion-picture film is used to do dubbing or rerecording work. The operator presses a store button to store the frame count of the frame being projected, and in this way stores all the frame counts for the starts and ends of several scenes, after which dubbing work is done on the thusly defined scenes. The current frame count of the film is indicated using an electronic multi-digit display unit having a row of controllable digit zones each of the 7-segment type and having controllable decimal point places. The multi-digit display unit is mounted upside-down, so that the decimal-point places are near the tops of the digit zones. The frame count is displayed on the digit zones with conventional appearance. The number of decimal-point places made visible at any given time indicates the number of the scene involved, both during initial frame-count storing work and during post-storing work on the scenes. If, during frame-count storing work, the operator tries to command storage of a frame count which intrudes into an already defined scene, the word "ERROR" is spelled out on the digit segments of the multi-digit display unit.
