流が流れ続ける。In the conventional power source control circuit of the massage machine, the power source control circuit is provided with a resistor to limit the amount of current output to the motor drive control circuit. The same amount of current flows through the resistor even when the motor is driven and when the motor is stopped and in a standby state.
Therefore, the amount of heat generated by the resistance, which is equivalent to the resistance loss, is the same when the motor is being driven or in the standby state. Since the massage machine using the power control circuit is not specified by the user of the massage machine, the power cord of the equipment is often connected to a power outlet for a long time. Then, since the power supply control circuit is in a standby state for driving the motor, current continues to flow in the resistor for a long time.

For this reason, not only does the massager's user feel distrust of the device due to a high temperature in the vicinity of the resistance of the massager, but the massager may be damaged or the user's safety may be reduced. There is a problem in terms of aspect.

Branched. The branched current flows, for example, between the emitter and collector of a PNP type transistor, causes the light emitter to emit light, and flows into the control circuit.

For convenience of description, the same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 shows a massage machine 10, in which a power supply control circuit 11, which will be described later, is housed. In FIG. 2, reference numeral 11 is a power supply control circuit, and a resistance R 2 is connected to a stage subsequent to the resistance R 1 of the power supply control circuit 11. In this embodiment, the resistors R 1 and R 2 have the same resistance value. Then, the resistance R 1
And a resistor R 2 are branched from an intermediate point between them and connected to the emitter E of the PNP type transistor 12. The transistor 12
The collector C is connected to the LED 6, and the other terminal of the LED 6 is connected between the resistor R 2 and the control circuit 5.

The current I 4 which is the standby current of the current I is supplied. The current I 4 requires about 50% of the current when the motor 4 is driven. Therefore, by connecting a resistor R 2 having the same resistance value as the resistor R 1 to the resistance value twice to a subsequent stage of the resistor R 1. Thus, the current I 1 rectified into a direct current by the rectifier circuit 3
Becomes a current I 4 reduced to about 50% of the current I 2 described in the conventional example by the resistors R 1 and R 2 and flows into the control circuit 4.

2 からの発熱量は微少となる。When the user selects each function, the microcomputer 13 applies a signal voltage for controlling the driving of the motor 4. The signal voltage is applied to the base B of the transistor 12 so that a current flows between the emitter E and the collector C of the transistor 12. Since the resistance value of the transistor 12 and the LED 6 is extremely small compared with the resistance value of the resistor R 2 , most of the current I 1 from the rectifier circuit 3 flows through the resistor R 1 and then The current flows through the transistor 12 to cause the LED 6 to emit light, and the current I 5 flows into the control circuit 5. The current I 5 during the driving is about twice as much as the current I 4 in the standby state described above. Since the current flowing through the resistor R 2 and flowing into the control circuit 5 is extremely small, the resistor R 2
The amount of heat generated from 2 is minimal.

に限定せられるべきものではない。Thus, as described above, by providing the resistor R 2 having the same resistance value as that of the resistor R 1 , the amount of heat generated from the resistor provided in the power supply control circuit is conventionally used when the motor 4 is driven. The amount of heat generated is the same as in the example, and the resistance value doubles in the standby state where the motor 4 is stopped, so the amount of heat generated can be halved. Although the resistances R 1 and R 2 have the same resistance value in this embodiment, the same effect can be obtained even if the resistance values are different, and the resistance values should not be limited to the same resistance value.

The amount of heat generated from the resistance can be reduced.
Thus, failure due to heat generation from the resistor can be prevented, durability can be improved, and danger due to heat generation can be eliminated to ensure safety.

効果を奏する発明である。Further, since the light emitting device such as an LED is connected to the subsequent stage of the transistor for controlling the signal current of the control circuit, it is not necessary to separately provide a circuit for causing the light emitting device to emit light, and the amount of heat generation can be reduced. It is an invention that achieves various kinds of effects, such as being able to.
