Claims

[Claims for Utility Model Registration] A plurality of light emitting elements, each corresponding to a plurality of light emitting elements, and detecting a light beam from each light emitting element, respectively, on at least one set of mutually opposing side edges of a panel display surface. a plurality of light receiving elements are arranged, and a plurality of first focusing lenses each converting the emitted light from each light emitting element into a parallel light beam;
The first lens body is arranged in front of the array of the light emitting elements with the first focusing lens facing each of the light emitting elements, and the first lens body is arranged in front of the array of the light emitting elements, and A second lens body is constituted by a plurality of second focusing lenses that focus on the respective light receiving element positions, and this second lens body positions the second focusing lenses at opposing positions with respect to each of the light receiving elements. The first and second lens bodies are integrally fixed to the light emitting element and the light receiving element, respectively, and in this fixed state, the first and second lens bodies are disposed in front of the array of light receiving elements. The second lens body has planar plate surfaces facing each other, and blocks the parallel light beam immediately before the panel display surface, thereby changing the position on the panel display surface corresponding to the blocked parallel light beam. A display surface position designation device configured to allow designation of a display surface position.
