Abstract

PURPOSE:To reduce cost for a moving object stop device by fitting one reflector to an object and decelerating and stopping the object moving in both directions. CONSTITUTION:The moving object 20 has the reflector 22 on a left surface and it is carried in the direction of an arrow A. Reflective photoelectric tubes 24 and 26 are arranged on the left of the moving object 20 at a prescribed interval L. A speed controller can decelerate and stop the moving object 20 based on the detection signal of the photoelectric tubes 24 and 26. Opening parts 30 and 32 are formed at a collimeter board 28 and they are formed in correspondence with the projection windows of the photoelectric tubes 24 and 26. The detection ranges 34 and 36 of the photoelectric tubes 24 and 26 can suitably be altered by suitably altering the opening areas of the opening parts 30 and 32 and distances (l). The detection ranges 34 and 36 are set so that they overlap with the moving line 20 of the moving object 20.
