STOPPING POSITION CONTROL DEVICE |
摘要 |
A stopping control device includes a stripe pattern formed on an object to be moved and a non-contact type sensor for sensing a boundary between the stripes of the pattern. The stopping mechanism stops the object after a predetermined time has passed after a boundary was sensed so that the sensor beam is positioned at an approximate center of a stripe. The sensor may be a photo reflector sensing a reflectance of each part of the stripes, to sense a boundary therebetween.
