Abstract: front page image
(EN)An optical touch panel has a touch panel configuration which provides superior accuracy in terms of position detection and is unaffected by external light. A touch panel (1) described herein is provided with: a sheet-like transparent light guide (11); detection elements (13a), (13b), (13c) which are disposed along each of three side surfaces (11a), (11b), (11c) of the light guide (11); and at least two detection light sources (12) which are disposed on a side surface (11d) other than the side surfaces (11a), (11b), (11c) on which the detection elements (13a), (13b), (13c) are disposed.
(FR)L'invention concerne un panneau tactile optique qui a une configuration de panneau tactile qui fournit une précision supérieure en termes de détection de position et est non affecté par la lumière externe. Un panneau tactile (1) décrit dans la présente invention comporte : un guide de lumière transparent de type feuille (11) ; des éléments de détection (13a), (13b), (13c) qui sont disposés le long de chacune de trois surfaces latérales (11a), (11b), (11c) du guide de lumière (11) ; et au moins deux sources de lumière de détection (12) qui sont disposées sur une surface latérale (11d) autre que les surfaces latérales (11a), (11b), (11c) sur lesquelles les éléments de détection (13a), (13b), (13c) sont disposés.
(JA) 光学方式のタッチパネルであって、位置検出精度に優れ、かつ、外光の影響を受けないタッチパネルの構成を得る。ここに開示するタッチパネル(1)は、板状で透明な導光体(11)と、前記導光体(11)の3つの側面(11a),(11b),(11c)のそれぞれに沿って配置された検出素子(13a),(13b),(13c)と、前記導光体(11)において、前記検出素子(13a),(13b),(13c)が配置された側面(11a),(11b),(11c)以外の側面(11d)に配置された、少なくとも2つの検出用光源(12)とを備える。
