Claim 11

In a player for use with a disc record enclosed in a protective caddy such that the respective sides of said record are associated with the corresponding sides of said caddy; said caddy being subject to insertion along a path into said player through an input slot to load an enclosed record therein; a record side identifying apparatus comprising: (A) a pair of electrical switches; (B) a pair of independently-operated actuating members disposed in said player in said caddy insertion path; each one of said actuating members operating the respective one of said switches; said actuating members being located such that they are operated respectively in a given and a reverse sequence depending upon which side of said caddy is uppermost during a caddy insertion; the sequence of operation of said actuating members determining the order in which said switches are closed; and (C) means responsive to the order of closure of said switches for providing an indication of the record side subject to play.

Claim 12

In a player for use with a disc record enclosed in a protective caddy such that the respective sides of said record are associated with the corresponding sides of said caddy; said caddy being subject to insertion along a path into said player through an input slot to load an enclosed record therein; a record side identifying apparatus comprising: (A) a pair of electrical switches; (B) a pair of independently-operated actuating members disposed in said player in said caddy insertion path; each one of said actuating members operating the respective one of said switches; said actuating members being located such that they are operated respectively in a given and a reverse sequence depending upon which side of said caddy is uppermost during a caddy insertion; the sequence of operation of said actuating members determining the order in which said switches are closed; and (C) means responsive to the order of closure of said switches for providing an indication of the record side subject to play.

Claim 13

The record side identifying apparatus as defined in claim 9 wherein each of said switches has a pair of contact elements; one of said elements of each of said switches being disposed on the respective one of said actuating members for making a contact with the other of said switch elements upon actuation.
