GRAVITY FEED WITH AXIALLY MOVABLE ATTACHING MEANS

摘要

Apparatus for reproducing information which is recorded on concentric tracks of rotary disk-shaped carriers has a continuously driven motor which can be connected with a centering and rotating device for carriers and with a carriage which shifts the reproducing head into registry with a selected track of a centered carrier. The motor drives a timer wheel for generation of synchronizing pulses which are transmitted to a revolution counter. A programming circuit which receives signals from the counter and from the reproducing head controls a unit which records the reproduced information.
