发明名称 Phonograph device
摘要 A toy phonograph for indexed playing of spaced concentric sections of interchangeable disc records. The phonograph includes an overcentering mechanism associated with a cam operated switch which is actuated by the introduction of a record through a slot in the front of the housing to initiate playing of the record, as well as an eject button for stopping play and ejecting the record from the phonograph. When a new record is inserted, the overcentering mechanism and the cam interact to automatically start the phonograph to play the new record. The tone arm automatically is indexed radially to play the next concentric record section upon each interchanging of a record and is returned to the first record section after playing the last section on the record.
