Abstract

PURPOSE:To achieve the simplification of construction and manufacture by using a mask which has two light receiving parts. CONSTITUTION:A chopper 1 which has a pair of blade parts 2, 3 is disposed between a light source 5 and a mask 8 which has first, second light receiving parts 15, 16 above and below a window 6, rotatably at a constant speed by means of a motor 4. Then, when the chopper 1 is revolved, one of the blade parts 2, 3 begins to cut off the light directing to the first light receiving part 15 before it cuts off the light derecting to the window 6 and finishes the cuttoff of the light directing to the first light receiving part 15 before it finishes the cutoff of the light directing to the second light receiving part 16 with a delay from the time when it has started the window 6 and begins to cut off the light directing to the cutoff of the light directing to the window 6. Hence, required electric signals may be generated without the need for forming the chopper 1 in a special shape or using any photocouplers.
