Abstract

PURPOSE:To make the stop position autonomously judgeable by installing two trains of bar codes, and changing each phase of the black and white to each other. CONSTITUTION:A bar code 11 is attached to a continuous part between a driver and a moving part of a breaker, and a bar code reading device 12 is attached to the corresponding position. The bar code 11 is divided into two bar code parts 11A and 11B, and a bar space between these parts themselves is shifted of its phase with each other little by little, and each phase of black and white is accorded with each other at the left end, but when it is reached to the right end, the black and white comes to the opposite phase. The reading device 12 also consists of two reading parts which are set up as corresponding to these bar code parts 11A and 11B respectively. With this constitution aforesaid, a fact that the breaker 3 is in any state is judgeable by interrelations of the black and white being detected by these two reading parts 12A and 12B.
