この発明は、人体から放出させる熱線を検知して、人体
の侵入を検出する赤外線式の熱検知器の検知方向表示構
造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a detection direction display structure for an infrared heat detector that detects intrusion of a human body by detecting heat rays emitted from the human body.
赤外線を検知する熱検知器は従来よりよく知られている
が、赤外線は目で確認できまいこと、および検知範囲を
広くするために複数の分割ミラーを用いた反射鏡として

時間がかかる欠点があり、また侵入警報に用いる場合な
ど確実に検知できるように設定できるか不安でもあるな
どの欠点があった。Heat detectors that detect infrared rays have been well known for some time, but infrared rays cannot be seen with the naked eye, and the detection range is limited because the reflector uses multiple split mirrors to widen the detection range. #1 As shown in Figure 1, there are multiple strip-shaped ranges, so it is extremely difficult to determine the detection range of the detector at the time of installation. Since it was a method, it had the disadvantage of being time-consuming, and there were also disadvantages such as whether it could be set to ensure reliable detection when used for intrusion alarms, etc.
本願発明は上記する欠点を改善することを目的とし、可
視光により検知範囲が目視できる検知方向表示手段を備
