を停止させる。As shown in FIGS. 41(at and 41b), in detecting the stop position of a moving object 2 using a conventional charging detector 1, one plate 3 is attached to the moving object 2 in a fixed width. The moving object 2τ is stopped by detecting a change in the electrical signal of the photoelectric detector 1 when the optical path 4 of the photoelectric detector 1 is blocked.
The moving object 2 does not stop at the same position in different situations in which the source '# blocks the optical path 4 of the detector l. Therefore, Figure 1 (
In order to always stop the moving object 2 in the state shown in a), a shielding plate is installed for the moving object 2 that has been moving from the left to the right on the rail 5 as shown in 3

け余分に時間かがかるという欠点があった。As shown in FIG. 2, (b), when the moving object 2 moves from the right direction to the left direction, the moving object 2 is moved to the position of the photoelectric detector 7 and stopped. ,
It is necessary to move the moving object 2 to the right again and detect the change in the electrical signal when the shield plate 3 blocks the optical path 4 of the photoelectric detector 1, process it in the computer 6, and stop the moving object 2. Regardless of the moving direction of the moving object 2, the moving object 2 must always be moved in a fixed direction and stopped at a predetermined position. Therefore, when the moving object 2 is moved from the right direction, the light emitting device 7 has to be moved once and then stopped at a predetermined position, which has the disadvantage that it takes extra time. Ta.

When the right end of the guide plate 3 blocks four optical paths of the photoelectric detector 10, the electrical signal of the photoelectric detector 1 changes. The change in the electrical signal at this time is processed by calculation@6, and the moving object 2 is stopped. Conversely, when the moving object 2 is moving from the right to the left, the moving object 2 is stopped due to the change in the electrical signal when the left end of the passing plate 3 blocks the optical path 4 of the photoelectric detector 1. First, when the moving object 2 is further moved and the right end of the path &3 passes through the optical path 4t of the photoelectric detector 1, the electric signal of the photoelectric detector 1 changes again. The change in the electric signal at this time is processed by the computer 6, and the moving object 2' is stopped and the slope is increased.

動物体停止位置検出方式。(2) Check the moving direction of an object moving on the rail by motor drive, and if the moving object is moving from the left to the right, the right end of the plate will be the photoelectric detector. The moving object is stopped by detecting the change in the electrical signal when it blocks the optical path, and when the object is finally moving from the right to the left, the left end of the shielding plate is in the optical path of the light 1 detector. Instead of stopping the moving object due to the change in the electric signal when it is blocked, the moving object can be stopped due to the change in the electric signal when the right end of the trace plate passes through the optical path of the photoelectric detector.
