PROBLEM TO BE SOLVED: To provide a measuring instrument capable of more precisely performing measurement or medical treatment without relying on the perception or memory of an operator when a region not directly observable is examined in its shape (depth, length, an angle, etc.) or medically treated, and an angle and distance detector used therein.SOLUTION: A direction indicating auxiliary means (7, 70 or 80) to be pointed to a reference direction is attached to the region, which is positioned at the tip part (2 or 91) of a manually operable implement for the purpose of examination or medical treatment or in the vicinity thereof, in a freely shakable manner. This direction indicating auxiliary means is pointed to the reference direction in order to index the position of the region impossible to observe directly to store the position of the region.COPYRIGHT: (C)2009,JPO&INPIT【課題】直視できない部位の形状(深さ、長さ、角度等)の診査、或いはそのような部位の施療を行う際に、術者の感や記憶に頼ることなく、より精確に測定や治療することが出来る測定装置及びそれに使用する角度・距離検出器を提供する。【解決手段】手動器具の先端部(2,91)に位置し、診査又は施療するための部位又はその近傍に、基準方向を指向させる方向指示補助手段(7,70,80)を揺動自在に取り付けたことにより、方向指示補助手段を、直視できない部位の位置の割り出しに基準方向を指向させ、それを記憶させる。【選択図】図1
