PURPOSE:To read out and change information recorded in plural identification parts without contacting identification parts with a reading part in an identification device by radiating respectively different and inherent identification pulse beams from respective identification parts. CONSTITUTION:When a person having an identification (ID) part 3 approaches the detecting range of a detector 4 in a body 2, the detector 4 detects the approach of the person and a light emitting device 5 in the body 2 generates a prescribed pulse beam in accordance with the detection. When the ID part 3 fixed on the person receives the prescribed pulse beam, an inherent pulse beam is radiated synchronously with the prescribed pulse beam. A light receiving device 6 in the body 2 receives the inherent ID pulse beam, converts the received pulse beam into an ID code signal and a display device 7 displays the ID code or the like based on the ID code signal. A computer 8 decodes information to be the contents of the ID code to decide or change the contents and displays the obtained result to the display device 7 through the body 2. |
