OPTICAL TOUCH PANEL AND VENDING MACHINE

WIPO Patent Application WO/2017/013953

A1

The purpose of the present invention is to provide an optical touch panel which can suppress deterioration of detection accuracy even when dust, snow, etc., has accumulated on retroreflective plates arranged in the lower frame of the optical touch panel, attenuating the amount of reflection from the retroreflective plates, and to provide a vending machine. To this end, this optical touch panel is provided with at least: a pair of retroreflective plates 22a, 22c which are provided inside of a pair of opposite left and right frame portions of a frame 21; an upper left detection unit 23a, an upper right detection unit 23b, a lower left detection unit 23c and a lower right detection unit 23d which are provided in the four corners of the frame 21, irradiate infrared light onto at least the retroreflective plates 22a, 22c, and generate a detection image on the basis of light reflected from the retroreflective plates 22a, 22c; and an operation determination unit 1 which detects a touch position on the basis of the detection image generated by the upper left detection unit 23a, upper right detection unit 23b, lower left detection unit 23c and lower right detection unit 23d.
