ABSTRACT:
A spring operated record player organ includes a base apparatus, a driving unit, a gear set, a fixed axle unit, a record player, and a rotation speed governor. The record player is able to rotate with the stable restoring force of a manually wound up coil spring so as to play rhythmical music pleasant to the ear. As this apparatus does not require electric power, it is conveniently usable anywhere.
