<p>PURPOSE:To execute the information arrangements of the comparison, decision, record, etc., of arriving orders, arriving times, etc., to the fixed position of a traveling object by executing the scanning of a laser beam, simultaneously, light-receiving the reflected light of the object to be detected, and decoding it. CONSTITUTION:A laser beam from a laser light source 1 is made to repeatedly scan in a fixed range in the position of G by a scanning mechanism 2 driven by a scanning signal from a driving circuit 3. On the other hand, to the tops of traveling objects 7, 7 and 7, the object 6 to be detected, to which recognition information is inputted, is made to adhere. When the traveling object 7 arrives at the line G, the laser beam is reflected in an incident direction and outputted to a photoelectric converter 8 by a semitransmitting mirror 4. A control part 9 calculates and memorizes the arriving orders, arriving times, etc., by executing an operation based on the individual information signal of the traveling object 7 from the photoelectric converter 8 and a synchronizing signal from the driving circuit 3.</p> |
