Abstract
PURPOSE:To prevent the generation of malfunction due to the influence of reflected light from a floor close to a guide tape by arranging a shutter capable of varying photodetecting width in front of a photodetecting part for photodetecting reflected light from the guide tape. CONSTITUTION:The guide tape 2 in a curved passage part has apparent wide width (W+DELTAW) expanded from real width W by DELTAW. The shutter 4 arranged in front of the photodetecting apt 3 is opened by a driving motor 5 in accor dance with the wide width and receives only the reflected light from the appar ently expanded width of the guide tape 2. The guide tape 2 in a straight passage part has the real width W and the shutter 4 is narrowed by the motor 5 in accordance with the real width. Consequently, light other than the reflected light from the guide tape 2 can be cut and the generation of malfunction due to reflected light from the floor 1 close to the guide tape 2 can be prevented.
