Generally, this type of timer device was started using an operation switch, but due to a failure in the laser diode, its control circuit, or drive circuit, the timer device would start even if no laser light was actually being output, making it appear as though the laser beam was not being output. It looked as if it were outputting. This is because currently commercially available laser diodes emit infrared light, and the irradiation state cannot be visually confirmed.

The present invention has achieved the above object by providing a laser diode that emits laser light, an output control means that controls the light emission output, a timer device that sets the light emission time, an operation switch that starts light emission, and a power supply device that drives these. This is achieved by a laser irradiation device characterized in that it detects the monitor light of a laser diode and uses this detection signal as a starting signal for a timer device. Note that if the timer device is not activated by the operation switch, it means that the device is malfunctioning.

This invention will be explained below with reference to Examples. FIG. 1 is a block diagram showing an embodiment of the present invention.
In this embodiment, the laser diode 7 outputs laser light after the probe 8 confirms that the operating switch 6 is turned on and the skin detection means 5 confirms that the laser aperture is in contact with the skin and the irradiation is OK. , Therefore, the operation switch detection signal and the skin detection signal are ANDed by signal lines 16 and 17.
The main control means 9 receives the output control signal line 14 under the condition.
In addition to outputting an output to This is used as a start signal for the timer device 11 which is an irradiation time setting means. Therefore, the presence or absence of laser irradiation and the starting and stopping of the timer device are synchronized, and the main control means 9;
When laser irradiation is stopped due to a failure in the output control means 3, skin detection means 5, laser diode 7, etc., the timer device also stops. Note that as long as the laser irradiation device is used as a treatment device, it is desirable to include the skin detection means 5 for safety reasons. Furthermore, a signal for intermittent laser output at the value of the modulation frequency set by the modulation setting means 10 is also sent via the 14 signal lines. Reference numeral 12 denotes display means for displaying the laser power setting value, modulation frequency setting value, irradiation time setting value, remaining irradiation time, and the like.
この発明はレーザ照射出力のモニタ光を検知し

し、合わせ装置の故障も同時に判定できる。
In this invention, the monitor light of the laser irradiation output is detected and the timer device is started based on the detection signal, so the laser output is completely synchronized with the set value, and failure of the alignment device can be determined at the same time.
