<p>PROBLEM TO BE SOLVED: To improve mount efficiency by supporting a sensorstoring part by a supporting part thereby making the sensorstoring part freely movable, and setting a weight mechanism to direct the detection area of a sensor element vertically downward at all times. SOLUTION: A mount stage 5 supports a sensor-storing part 2 and fixes a detecting apparatus. A supporting part 6 holds and supports the sensor-storing part 2, so that the sensor-storing part 2 can move freely. An opening of a size not to allow the sensor-storing part 2 to fall is opened at a bottom face of the supporting part 6, thereby preventing a detection area of a sensor element 1 from being interrupted by the supporting part 6. Even when the detecting apparatus is set at a ceiling, a beam or the like having an inclination, the sensor-storing part 2 is freely movable to the mount stage 5 and moreover the sensor element 1 is always directed by a weight mechanism 9 to a lower part of the detecting apparatus irrespective of a set angle of the mount stage 5. Therefore, the detection area can be set immediately below the detecting apparatus even without special setting.</p> |
