In FIG. 2, reference numeral 13 denotes an operation switch (not shown) for setting a mode, which is mounted on the upper or vertical surface of the inclined surface of the case body 2;
Is a CPU of the control board 11, 15 is a RAM connected to the CPU 14, and 16 is an R connected to the CPU 15.
OM and 17 are EEPROMs connected to the CPU 14.

Next, the operation will be described based on the above configuration. First, various modes, which are standard operating conditions at the time of factory shipment, are stored in the ROM 15. When the subject performs a treatment under general operating conditions, the operation switch 13 is used.
Can be selected to perform treatment.

If it is determined from the contents of various treatments and the nature of the hair of the subject that the treatment cannot be performed in the preset mode, the operation shown in the flowchart of FIG. It is registered and stored in an EEPROM 17.

First, the power of the hair treatment accelerating device is turned on (step S1), and the operation switch 13 is operated to select a mode of the operating condition which is considered to be the most suitable from the modes stored in advance (step S1). Step S2). Then
In the selected mode, the temperature level to be set, the heating time, and in the case of a swing operation, the swing angle are changed by the operation switch 13 in accordance with the treatment contents of the subject, the medicine and the properties of the hair (step S3). .

Then, it is determined whether the practitioner wants to store the data in the memory under the set conditions (step S4).
If it is determined that the setting mode is desired to be stored in the EPROM 17, the mode switch of the operation switch 13 is kept pressed for a predetermined time or more (step S5). When the setting mode is stored in the RAM 15, a buzzer sounds to notify that the setting mode has been stored ( In step S6), the operating conditions desired by the practitioner are stored.

Accordingly, by selecting the most suitable operating condition from among a large number of operating conditions stored in the EEPROM 17 in accordance with the contents of the treatment performed by the practitioner and the medicine to be used, the treatment is performed. This can be performed and does not require the operator to perform any troublesome setting work.

Next, a case in which the camera is tilted or falls over for some reason will be described. Now, for example, the inclination sensor 1
When the hair processing promotion device is tilted beyond the angle set in advance by 1a, the tilt sensor 11a detects the tilt and outputs a signal to the CPU 14, so that the CPU 14
Cuts off the power supply to the motor 3 and the heater 73.

Thus, even if the hair treatment accelerating device falls down, the power supply to the motor 3 and the heater 73 is cut off, thereby causing a fire or the practitioner to turn the device on. Case 7 even if touched
1 does not cause any injuries because it is stopped.

Next, the heating device 7 is rotated, or
The operation in which the rotation is stopped and the rotation is reversed not only in one direction but also in a fixed cycle will be described. Conventionally, only the energization and cutoff of the motor 3 is controlled by a command from the CPU. However, in this embodiment, when the motor 3 is started and the rotation direction is reversed (hereinafter referred to as swing), the motor 3 is started. A plurality of cycles in the waveform of the AC power supply to be applied to the power supply, and a half cycle or a cycle less than the plurality of cycles after that, suppress the shock at the time of start and stop by repeating the energization method a plurality of times such as shutting off the power supply, In addition, vibration of the arm 7 attached to the ceiling and the heating device 7 attached to the column 1 can be prevented.

That is, as shown in FIG. 4, the operation of energizing the motor 3 for two cycles of the power frequency at the time of initial power-on or reversal and interrupting the energization of the motor 3 for the subsequent half cycle is performed 10 times. By repeating this, the motor 3 rotates slowly during the control from the start of the start up to the tenth time, so that the shock at the start is reduced.

As another control method, a start-up switch or a switch for connecting / disconnecting a resistor connected in series to the motor 3 in response to a swing start command signal is set to the CP.
This can be performed under the control of U14. That is, by connecting the resistor and the motor 3 in series for 0.3 seconds after the start, the voltage applied to the motor 3 is reduced, the starting torque is reduced, and the starting shock can be reduced.

Since this embodiment includes the non-contact thermometer 8 and the visible light emitting device 9, first, the light source 9a of the visible light emitting device 9 is turned on and the lens 9b is turned on.
Is set so that the light converged by the above becomes the center position of the back of the head of the subject, that is, the position where the non-contact thermometer 8 measures the temperature of the hair.

When the heater 73 is energized and the motor 3 is energized, the heater 73 heats the subject at a constant temperature while rotating the entire head.
It promotes hair treatment, promotes drying of hair washing, promotes dyeing, and favorably performs permanent waving of hair.

As described above, the temperature of the hair of the subject is measured by the non-contact thermometer 8, and the temperature is adjusted. At this time, if the non-contact thermometer 8 breaks down, the power to the heater 73 is continuously supplied. And the temperature becomes abnormally high. Therefore, in the present embodiment, when the temperature does not reach the preset temperature even after the elapse of the certain time, that is, when the non-contact thermometer 8 is out of order, the set temperature is not detected. The output of the total 8 is a low value signal from the CPU 1
4 is output.

Accordingly, the CPU 14 monitors the signal from the non-contact thermometer 8 with respect to the set time. If the signal from the non-contact thermometer 8 is small, the power supply to the heater 73 is turned on and off to perform an abnormal operation. The control is performed so as to prevent heat generation, or the operation is performed to cut off the power supply to the heater 73 and to ensure the safety of the hair of the subject due to abnormal heating.

When such an abnormality occurs, the user's palm close to the front of the non-contact thermometer 8 for which the approximate temperature is known in advance, for example, is approached. If the temperature detected by the contact thermometer 8 is several times C
By displaying via the PU 14, the non-contact thermometer 8
It is possible to judge whether or not there is an abnormality. Therefore, in such a case, the repair can be performed by replacing only the non-contact thermometer 8, and waste such as replacing the conventional control board 11 can be prevented. You can do it.

In the present embodiment, the disk 12 having the slits 12a _{1 to} 12a ₆ as shown in FIG.
By detecting the A1～12a ₆ in photocoupler 12b, it is possible to stop the heating device 7 at all times a constant home position, also, it is possible to reciprocally rotate the heating device 7 at a constant rotational angle (swing), Further, the temperature can be taken in by the non-contact thermometer 8 at a position not obstructed by the heating device 7.

First, the operation of stopping the rotating heating device 7 at the home position will be described. When the operator performs a stop operation with the operation switch 13 or when the time reaches a preset operation condition mode, the CPU 1
4, when the stop command is sent, the photocoupler 12b first stops the disc 12 with a narrow slit 12a.
₂ (for clockwise rotation) or a narrow stop slit 12a ₃ (for counterclockwise rotation). CPU14 that has received the detection signal, for example, by turning off the power to the motor 3 is judged to be the home position is reached slits 12a ₁ within 0.5 seconds, the heating device 7 at the home position It will stop.

[0034] Incidentally, in the product of the present embodiment, 10-degree rotation (0.5 seconds) from the detection of the slit 12a ₂ or slit 12a ₃ Then slit 12a ₁
And stops at home position.

Next, the operation of swinging the heating device 7 will be described. Since the heating device 7 always detects the home position as described above, the angle of the swing, that is, the number of rotations and the number of rotations, And the elapsed time after passing the home position
, And after this time has elapsed, the direction of energization to the motor 3 is reversed so that the swing operation can be performed. The reversal angle of this swing is up to 90 degrees and the minimum is 20 degrees.

The non-contact thermometer 8 always measures the hair temperature at a predetermined position of the subject.
The temperature of the cover 71 is measured twice in one rotation of the heating device 7 because the heating device 7 is rotating. The temperature of this cover 71 is
Is heated through the reflection plate 72, and is higher than the temperature of the hair. Therefore, if the temperature from the contacted thermometer 8 is always taken in, it will be higher than the hair temperature as an average value.

Therefore, in the present embodiment, the sensing slits 12a ₄ , 12a ₅ , 12a at positions where the measurement by the contacted thermometer 8 does not pass through the cover 71.
Data ₆ is taken from the contacted thermometer 8 when the CPU 14 receives a signal detected by the photocoupler 12b, and is adopted as data for controlling the temperature of the heater 73. As a result, the temperature control of the heater 73 can accurately follow a preset value.

In the above-described embodiment, the case where the nonvolatile EEPROM 17 is used as the memory has been described. However, as the other memory, the volatile memory is used, and at the time of a power failure, data is retained by a backup battery. You may do so.
