Abstract

PURPOSE:To reduce the number of component parts and manufacturing processes and to eliminate the variance of the panel accuracy, by providing the light shielding bodies at the places near the light emitting or photodetecting chips arrayed on a substrate together with a long lens body set continuously with the prescribed spaces secured to said chips. CONSTITUTION:The light emitting or photodetecting element chips 13 are arrayed and bonded with fixed spaces in the lengthwise direction onto a printed board 12 serving as the base of an array 11 of a photoelectric touch panel. The light shielding bodies 14 having the prescribed height H are provided in a body with the board 12 at the places of the chips 13. In addition, a long acrylic resin lens body 15 having a semicircular section is set with a prescribed space secured to those chips 13. A projection 15a for junction formed on the bottom surface of the lens body 15 is set between bodies 14. Thus it is possible to reduce the number of components and manufacturing processes and to eliminate the variance of accuracy of a photoelectric touch panel.
