Abstract

PURPOSE:To obtain plural pieces of information about height without moving parts by providing plural parts irradiating optical systems which irradiate rays from light sources of photoconductor laser from the upper part of the parts to be measured slantingly and a television camera enabling the pick up image from above the parts to be measured and emitting the rays from the light sources in order. CONSTITUTION:The title detector is composed of the plural part irradiating optical systems 13-1 and 13-2 which irradiate the rectilinar rays 11 from the upper part of the parts 12 slantingly and the TV camera 14 picking up the reflected rays from the parts 12 irradiated with these optical systems from right above the parts 12. The plural part irradiating optical systems 13-1 and 13-2 are composed of cylindrical lens 15 and 16 making the rays from the laser light sources 10 rectilinear respectively and controlled from a controller 17via drivers 18 so that the parts 12 are irradiated from the different positions respec tively and further, the plural light sources 10 emit the rays in order. Hereby, since the parts 12 can be irradiated with the plural part irradiating optical systems 13-1 and 13-2, plural pieces of information about the height can be obtained at a stationary state of the parts by the TV camera 14.
