し，カーソルの動きをコントロールする方向指定装置が
使用されてきた。With the recent development of electronic technology, various information processing devices that handle information such as figures and characters have been put into practical use. Along with this, the opportunity for humans to directly input predetermined coordinates into a computer or the like has increased, but in the past, the light source side was made pen-like and movable. Directional devices have been used that control the movement of the cursor by inputting coordinates with the detection element fixed.
ところが従来この種の装置においては，カーソルをコン
トロールし，座標を指定する際にペンを使用するため人
間の手ブレが不可避であり，こまかな座標指定は不可能
であった。However, conventionally, in this type of device, since the cursor is controlled and a pen is used to specify coordinates, human hand shake is unavoidable, and detailed coordinates cannot be specified.
本考案はこのような問題点を解決するためになされたも

することによって，光源がペン状であることに起因する
手ブレを排除しこまかな座標指定が安定して行える座標
入力装置を提供するものである。The present invention has been made to solve such a problem. By fixing the light source side and making the semiconductor optical position detection element movable, the camera shake caused by the pen-shaped light source is eliminated. It is intended to provide a coordinate input device capable of stably specifying detailed coordinates.

For example, as shown in FIG. 1, this recess is tapered and has a high reflectance (for example, metal or the like is deposited).
Thus, the light from the point light source 2 can be effectively applied to the semiconductor light position detection element 1.

It is a fact of public knowledge. Further, in order to specify a desired coordinate to a computer or the like, it can be performed by moving the movable semiconductor light position detecting element 1 by the guide rails 41 to 42.
以上の説明から明らかなように，光源をペン状にして移
