摘要： A device for counting the number of record disc sides played on a phonograph includes a support member or pedestal which is mounted on the motor board of the phonograph outwardly of the turntable. An actuating member is pivotally mounted on the pedestal so as to project into the path of a record disc moving along the upstanding axial spindle of the turntable and a digital counter is electrically or mechanically coupled to the actuating member so that, as a record disc moves downwardly along the axial spindle, the digital counter is caused to undergo unit advance actuation whereas no such actuation occurs on removal of a record disc upwardly along the turntable spindle.
