What does 4A 16mm projector look like?

4A 16mm projector is a machine, its claws are too long and the picture jumps.

8 mm camera: 1932, after the advent of 8 mm film, it provided an economical and light shooting method for filmmakers and enthusiasts.

Camera 16mm: 1923, marketed by Kodak Company in Heismann.

Camera 35 mm: 1925, the Paris International Film and Photography Work Conference invented Edison and Lumiere as the film ratio of standard silent films.

Film conveying part:

The rolled film is sent from the film supply tray to the film window to reflect the picture, and the optical vocal cord signal is converted into audio current through the echo part. Then roll up the projected film again. It consists of film supply and take-up box (or film arm), film feeding gear, intermittent motion mechanism, various pulleys, film door and frame adjusting device.

Movable projectors with narrow films usually use intermittent film grasping mechanisms instead of intermittent film conveying devices. The core part of the film projector is the intermittent motion mechanism, which changes the continuous rotation into intermittent rotation, and cooperates with the shading plate to make the film stay in the film window stably when the light passes through and image clearly on the screen.
