发明名称 45 RPM Automatic play adaptor
摘要 A 45 rpm record adaptor body is positioned at the center of the turntable and has a record supporting shelf on one side and a shoulder opposite said shelf. The distance from the inner edge of said shelf to the bottom of said shoulder is slightly greater than the hole diameter of a 45 rpm record so that one side of a stack of 45 rpm records placed on said body is supported on said shelf and the other side of the stack is supported on said shoulder. The shelf is undercut to a point at which the distance to the bottom of said shoulder is less than the hole diameter of a 45 rpm record to permit an ejected record to move off of said shoulder and onto the turntable.
