障か否かが判別できないという問題点があった。(Problem to be solved by the invention) However, in conventional identification devices, when checking the operation, the only way to check the operation is to check the operating state of the light receiving section on the receiver side. There was a problem in that it was not possible to determine whether or not the identification device was out of order.

信号が送信されるようになっている。FIG. 1 is a circuit diagram showing an embodiment of the present invention, and shows the configuration of a light emitting section. This light emitting part has two light emitting elements t.
That is, an infrared light emitting diode D that emits infrared light and a visible light emitting diode D2 that emits visible light are provided. Figure 1(a) shows these light emitting diodes D, ,D
, are connected in series, and FIG. 1(b) shows an example in which they are connected in parallel. And these light emitting diodes D1. A transistor Q is connected in series with D2, and by turning ON and OFF this transistor Q by the driving section 3, a blinking signal of light is transmitted from each light emitting diode D, D2.

Visible light is also emitted at the same time as a.

きる。内蔵電池が消耗した時にも、同様に動作確認を行
うことができる。Therefore, when a malfunction causes light to be emitted, it can be easily determined whether the device is malfunctioning or not. In other words, if no transmission operation is performed, no visible light is emitted and it can be confirmed visually. You can also check the operation even when the built-in battery is exhausted.

ることができる。Here, consumption of the built-in battery must be minimized, but from this point of view it is also undesirable to provide the identification device with a pilot lamp for checking operation, and in this embodiment, a light emitting diode D2 with low power consumption is used. The consumption of the battery will be less than the number of times the battery is used. Furthermore, since the time for transmitting the identification code is very short compared to the operating time of the device, it is possible to check the operation and to suppress battery consumption.

ある。As explained above, according to the present invention, visible light is emitted in synchronization with infrared light transmission, so when a malfunction occurs such as when the battery is exhausted, it is easy to determine whether or not the device is malfunctioning. This has the advantage that it is possible to perform operation confirmation without significantly increasing power consumption.
