る。A lock confirmation device using this electromagnetic coupling communication system is composed of a main device and a sensor device housed in a door separated from the main device. The main device includes a signal generating section that generates a specific monitoring frequency signal, a detecting section that detects the presence or absence of an echo from the sensor device, and transmits the generated signal of the signal generating section to the sensor device by electromagnetic coupling. and a first antenna that receives echoes from the sensor device, a changeover switch that selectively connects the signal generation section and the detection section to the first antenna, and a changeover switch that connects the signal generation section and the detection section at a constant cycle. It is configured to include a control section that switches to each side, and a display section that displays the detection results of the detection section. The sensor device also includes a second antenna that receives the monitoring frequency signal from the signal generator through electromagnetic coupling and transmits an echo resonated with the signal to the main device, and a second antenna that receives the monitoring frequency signal from the main device. A resonant circuit corresponding to the second antenna and a reat switch inserted between the second antenna and the resonant circuit and turned on/off in conjunction with locking and unlocking of the door.

在から戸の施解錠状態を検知できる。As a result, if the leet switch is turned on in conjunction with the locking of the door, the sensor device will resonate with the monitoring frequency signal received through the second antenna, as the resonance circuit will be closed with the second antenna. The circuit resonates, and echoes due to the resonant current are received by the first antenna through electromagnetic coupling. When the REET switch is off, the second antenna is disconnected and the above-mentioned echo does not occur. Since the echo received via the first antenna is input to the detection section of the main device, the detection section can detect the locked/unlocked state of the door from the presence of this echo.

よってオンしてしまうことかあり、施錠確認の信頼性か
低い。For this reason, the leet switch may be turned on due to the upward movement of the rotary engagement member, and the reliability of locking confirmation is low.

Therefore, there is a limit to the improvement in the transmission and reception performance of the second antenna, and there are disadvantages such as a limited degree of freedom in selecting the relative installation positions of the main device and the sensor device.
