Abstract

A disk, tape, etc. record member is contained in a cartridge or cassette. A cartridge type record player has a movable receptacle for receiving the cartridge. The receptacle has two stable and one momentary positions. A center stable position is a load position wherein the cartridge can be inserted into the receptacle. A second stable position, on one side of the center position, is a play position wherein a transducer is in operative association with the second member. The third and momentary position on a second side of the center stable position causes a spontaneous ejection of the cartridge from the receptacle. Usually, from the eject position, the receptacle returns to the center stable position.
