To surely guide a visually handicapped person to the mark position of a bar code by incorporating a reflector and a non-reflection part to a mark for guiding the visually handicapped person and performing read without contacting by a cane to which a diffusion restoration type infrared ray sensor is incorporated.

In order to discriminate that it is for the visually handicapped person, this bar code alternately uses the reflector 2 and the non-reflection part 3 for instance and is installed so as to make a straight line perpendicular to a read direction. Walking is performed from left to right along the visually handicapped person guiding mark 1 by using the cane A provided with a read function. Then, a structure for starting vibration at the time of arriving on the start mark of the non-reflection part 3 of the bar code for guiding the visually handicapped person and stopping the vibration at the time of arriving on the reflector 2 when advancing is performed further is attained. When advancing is performed further, the non-reflection part 3 and the reflector 2 are alternately arranged in a bar code shape, transmission is performed to a user as signals by long and short vibration and facilities/equipments present in an advancing direction nearby are concretely guided from the code set beforehand.
