Title:
POWER SUPPLY CONTROL CIRCUIT OF MASSAGE MACHINE
Document Type and Number:
Japanese Patent JP3393266
Kind Code:
B2
Abstract:
PURPOSE: To improve the durability and safety by reducing the exothermic quentity from a resistor in waiting condition of a massage machine.
CONSTITUTION: A resistor R1 and a resistor R2 are connected in series between the line and the -line of a shunt regulator power circuit, and the emitter E of a PNP-type transistor 12 is connected to the middle point between the resistors R1 and the resistor R2. The collector C of the transistor 12 is connected to the rear stage of the resistor R2 through a light emitting diode 6. The rear stage of the resistor R2 is connected to a control circuit 5, and also the signal output terminal 14 of a microcomputer 13 is connected to the base of the transistor 12. When it is in waiting condition where the signal to drive a motor 4 is not outputted from the microcomputer 13, the resistance value is set higher by the resistor R1 and the resistor R2, so the exothermic quentity from the resistor R1 and the resistor R2 decreases.
