Abstract

PURPOSE:To reduce the mount space of a reflection type touch panel and to compact the touch panel by arranging light emitting elements and photodetecting elements on the same side and providing a reflection plate on the opposite side. CONSTITUTION:The photoelectric detection type input device is constituted by arraying photoelectric elements composed of a couple of a light emitting element 1 and a photodetecting element 2 in an X and a Y directions and detects and transfers the X and Y coordinates of a light beam which is cut off by addressing individual photoelectric elements 1 and 2 by a control part 4 to a processor 5. In this case, the light emitting elements 1 and photodetecting elements 2 of the photoelectric elements are arrayed on the same side and the reflection plate 3 is provided on the other side. Then, a light beam reflected by the reflection plate 3 on the opposite side is detected by a photodetecting element 2 to detect the touch input position.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、タッチ入力装置に関し、特に、光電検出方式
のタッチ入力装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a touch input device, and particularly to a photoelectric detection type touch input device.

〔従来の技術〕[Conventional technology]

従来、この欅のタッチセンサは、発光素子と受光素子を
対向させ、発光素子から出た光の有無を受光素子で検出
する方式が採用されていた。Conventionally, keyaki touch sensors have adopted a method in which a light-emitting element and a light-receiving element are placed opposite each other, and the light-receiving element detects the presence or absence of light emitted from the light-emitting element.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

上述した従来のタッチセンサは、Ｘ方向（左右の両側）
とＹ方向（上下の両側）にそれぞれ発光素子と受光素子
を対向させて配列している為、各素子への接続が４方向
から行わｎなければならないという欠点がある。The conventional touch sensor described above is
Since the light emitting element and the light receiving element are arranged facing each other in the Y direction (both upper and lower sides), there is a drawback that connections to each element must be made from four directions.

〔問題点を解決するための手段〕[Means for solving problems]

本発明のタッチセンサは、発光素子の光を受光素子で検
出することを利用し、発光素子と受光素子を同一側に配
列し、対向側に反射板をおくことによシ発光素子からで
た光の反射光を受光素子で検出する機能を有している。The touch sensor of the present invention utilizes the fact that light from a light-emitting element is detected by a light-receiving element, and by arranging the light-emitting element and the light-receiving element on the same side, and placing a reflector on the opposite side, light emitted from the light-emitting element is detected. It has a function of detecting reflected light with a light receiving element.

ることができる。FIG. 1 shows an embodiment of the invention. The light emitted from the light emitting element 1 hits the opposing reflecting plate 3, and the reflected light is detected by the light receiving element 2. By arranging these in the X and Y directions, a light lattice can be created. In the control unit 4, address each photoelectric element and switch the control line connected to each light emitting element.) Which light emitting element is to emit light and which light receiving element is to detect the light. I can see if there are any. By blocking this light with a finger, the X and Y coordinates of the blocked light beam are detected and transferred to the processor 5. In this way, any position can be detected.

〔発明の効果〕〔Effect of the invention〕

以上説明したように本発明は、発光素子と受光素子を同
