PURPOSE:To adjust the position of a detecting means with high precision and to make a device simple and small-sized by adjusting the position of the detecting means through screw members. CONSTITUTION:In case of position adjustment, an adjusting screw 12 is rotated in the direction of an arrow E or F by a driver 12 in the state, where screws 3 and 3 are fixed temporarily, to displace a screw 9 in the direction of an arrow A or B. Then, a supporting plate 2 is displaced in the same direction through long holes 1d and 1d, and a track 00 switch 4 is displaced in the same direction to adjust the position. After position adjustment is terminated, screws 3 and 3 are tightened to fix the supporting plate 2, and the position of the switch 4 is fixed. As the result, the supporting plate 2 is pressed in the direction of an arrow B by a slide spring 11 during adjustment as well as after adjustment, and play is not generated in the supporting plate 2, and high position precision is attained. |
