Abstract

PURPOSE:To detect record size in the absence of touch simply by placing a record disc on the turntable and make possible automatic playing by providing start switches, a magnet and detecting pins on the turntable. CONSTITUTION:When, e.g., an EP record disc 13, is placed on a turntable 1, only the first detecting pin 7 is pushed downward against a spring member 5, as a result of which the first magnet 4 approaches to the first lead switch 8, causing the first lead switch 8 to go ON and the record to be automatically played. Here, the second lead switch 12 is OFF, hence the turntable 1 rotates at 45 rpm. In addition, the lead-in position of the stylus tip of a pickup is so set as to oppose to the EP record disc 13. In this way, the record may be automatically played in the absence of touch simply by placing the same on the turntable.
