Abstract
A video disc player has a record extraction mechanism to facilitate record loading and unloading while the record remains enclosed in its caddy. The caddy comprises a record retaining spine releasably secured to an outer sleeve by means of a pair of spine locking fingers extending from the opposite edges thereof. A pair of spine releasing members engage and deflect the spine locking fingers to release the spine from its sleeve when a caddy is inserted into the player. Simultaneously, a pair of spine latching members hookingly engage the spine to hold it in place so that the record/spine assembly is retained inside the player when the sleeve is withdrawn. When the sleeve is reinserted into the player to recapture the record/spine assembly, it engages and drives the spine releasing members against the spine latching members in a manner freeing the spine. The caddy is then extracted. The spine releasing members and the spine latching members are both mounted on a shaft which is disposed at right angles to, and spaced apart from, the caddy insertion path.
