ABSTRACT:
As an empty caddy is inserted into a video disc player to retrieve a record retained inside the player, it engages and drives back a pickup carriage to its starting position at the rear of the player. As this happens, a coil spring, connected to the carriage, is stretched such that it urges the carriage to move toward the front of the player. During playback, a timing mechanism coupled to the carriage controls the rate of travel by means of an escapement of the carriage under the influence of the coil spring.
