摘要	PURPOSE:To prevent a laser light from being outputted in the case of contact with an object excepting for a human body by providing a touch detecting means to detect that a laser light radiating port touches an irradiated body and a temperature detecting means to detect a temperature near a part to be touched, especially, to detect a body temperature and controlling a laser light source by the outputs of these detecting means. CONSTITUTION:Probes 9a and 9b, a thermistor to detect the body temperature and a temperature sensor 10 such as thermocouple, etc., are provided in the tip of an irradiating port 10. An electric signal to be proportional to the temperature, which is obtained from a sensor circuit 25, distinguishes an electric signal corresponding to the temperature almost near the body temperature by a wind comparator 26 and a body temperature signal is sent to a logical product circuit 13. When a touch signal and a temperature signal are sent together, the logical product circuit 13 sends a signal to a central processing unit 14. Only when such a signal is sent, the central processing unit 14 energizes a semiconductor laser diode and radiate the laser light. Thus, when a probe 2 touches the object excepting for the human body, the laser light is not radiated since the temperature signal is not sent.
其他摘要	用途：通过提供检测激光辐射口接触被照射体的触摸检测装置和温度检测装置检测温度，防止在与人体接触的情况下输出激光特别地，在要触摸的部分附近，通过这些检测装置的输出来检测体温并控制激光光源。组成：探测器9a和9b，一个检测体温的热敏电阻和一个温度传感器10，如热电偶等，设置在一个辐射端口10的尖端。电信号与温度成正比，这是获得的来自传感器电路25，通过风比较器26区分对应于几乎接近体温的温度的电信号，并且将体温信号发送到逻辑乘积电路13.当触摸信号和温度信号一起发送时，逻辑乘积电路13将信号发送到中央处理单元14.只有当发送这样的信号时，中央处理单元14才激励半导体激光二极管并辐射激光。因此，当探头2接触除人体之外的物体时，由于不发送温度信号，所以不照射激光。
