PROBLEM TO BE SOLVED: To provide a door position detection device capable of improving reliability while detecting a door position with a high degree of precision.SOLUTION: A door position detection device D includes a permanent magnet 10 provided to a door 81 that forms a magnetic field, a magnetic sensor 20 provided to a case 82 that detects the strength of the magnetic field, and a position detection circuit 40 that detects the position of the door 81. The strength of the magnetic field that the magnetic sensor 20 detects is configured to change with the movement of the door 81. The position detection circuit 40 detects the position of the door 81 based on the strength of the magnetic field that the magnetic sensor 20 detects.SELECTED DRAWING: Figure 1

    【課題】高精度でドアの位置を検出しながらも、信頼性の向上を図ることが可能なドア位置検出装置を提供すること。【解決手段】ドア位置検出装置Dは、ドア81に設けられ、磁界を形成する永久磁石10と、ケース82に設けられ、磁界の強度を検出する磁気センサ20と、ドア81の位置を検出する位置検出回路40と、を備え、磁気センサ20が検出する磁界の強度は、ドア81の移動に伴って変化するように構成され、位置検出回路40は、磁気センサ20が検出する磁界の強度に基づいてドア81の位置を検出する。【選択図】図1
