Claims (1)

[Claims for Utility Model Registration] A first switch that turns on and off in conjunction with the movement of the tone arm and turns off when the tone arm is in the rest position; and a second switch that turns on and off when the tone arm reaches or passes the final tone groove on the record, and the tone arm turns off in conjunction with this, While the tone arm leaves the rest position and moves over the record until it reaches the final tone groove on the record or passes the final tone groove, the tone arm is turned through the first and second switches. In a device that supplies a power supply voltage to a motor circuit of a table drive motor, a switching element is provided in the power supply path to the motor circuit, and the switching element is connected to the first and second positions when the tone arm is away from the rest position. The switching is controlled by a timer circuit that operates to discharge when both switches are turned on and the tone arm is charged and the second switch is turned off as the tone arm moves further. The switching element is made conductive in conjunction with the charging operation of the timer circuit to supply a power supply voltage to the motor circuit, and the switching element is made conductive for a predetermined period of time by the discharging operation of the timer circuit after the second switch is turned off. An auto-stop device for a record player, characterized in that it maintains the supply of power supply voltage to the motor circuit.
