Description of the Related Art Generally, when an object to be heated is heated using a heater that generates infrared rays, the temperature of the object to be heated depends on the output of the heater, the distance between the heater and the object to be heated, and the object to be heated. It changes depending on the plate thickness or size of the heated object, the color of the object to be heated, and the like.

難であるという問題がある。In the case of the thermocouple type thermometer described above, since it is necessary to bring the part of the thermocouple into contact with the object to be heated, an uncured coating film or the like which cannot be contacted is formed. There is a problem that it cannot be used to measure the temperature of a heated object. In addition, if you use a radiation thermometer, it is possible to measure the temperature in a non-contact manner, but since the temperature of the heater body that reflects on the object to be heated may be measured, the accurate temperature of the object to be heated can be measured. There is a problem that it is difficult to measure.
From the above, there is a problem that it is extremely difficult to perform accurate automatic temperature control, that is, feedback control, by the conventional temperature measuring means.

However, temperature variations are large due to mistakes in setting heating conditions, changes in environmental conditions, etc., and this causes quality defects.

度制御をすることができる。According to the portable heater having the above structure, the infrared rays radiated and reflected from the object to be heated are detected by the non-contact temperature sensor, and the electric signal corresponding to the wavelength of the detected infrared rays is detected by the non-contact temperature sensor. When the electric signal is output, the electric signal is cut off by the circuit breaker at a wavelength in the short wavelength region, that is, the component corresponding to the infrared wavelength from the heater, and the electric signal passing through the circuit breaker is amplified by the amplifier and then controlled. -When input to the controller, the controller sends a signal to the current regulator to decrease the current flowing in the heater if the maximum value of the input electric signal is less than the preset heating condition value. On the other hand, when the heating condition value is exceeded, a signal for increasing the heater energizing current is output. Therefore, the current regulator adjusts the heater energizing current based on the signal. Therefore, the temperature of the object to be heated can be automatically controlled based on the wavelength of the infrared ray emitted from the object to be heated without being affected by the infrared rays from the heater.

At B, the reflected infrared ray α is eliminated by the action of the circuit breaker or the optical interference filter. Then, the amplified electric signal is output from the non-contact temperature sensor B to the controller C in a state where only the electric signal corresponding to the radiant infrared ray β of the object to be heated E is amplified.
