（図１０のａ参照）。Referring to FIGS. 5 and 6, the sensor unit 2 includes a light source (cold cathode discharge tube) 21, a film mirror 26, an optical fiber 22, condenser lenses 23 and 23, a light receiving substrate 24, and a unit case 20. Sensor board 25
The interior is constructed. The sensor unit 2 is maintained at a set position which is close to and faces the monitoring line A shown in FIG. 3, but when it is necessary to move to the retracted position shown in FIG. The drive gear 6 is rotated in the B direction (FIG. 7B) by the motor driving by the reverse rotation of the motor, and the pin 9 in the notch 15 of the pressure plate 13 is used to press the pressure plate 1.
3 moves in the B direction, and the sensor unit 2 rotates in the B direction until the electric motor 6 is stopped by the operation of the limit switch 16 and moves to a predetermined retracted position when the electric motor 6 is stopped (FIGS. 5 and 5). 7b). When returning from the retracted position to the set position, the electric motor 5 is rotated in the forward direction to rotate the drive gear 6 in the direction (b in FIG. 7), and the pressure plate 1 is rotated.
The pin 9 in the notch 15 of 3 is rotated in the a direction. The pin 9 rotates in the A direction to compress the elastic body 8 (see a in FIG. 8). When the pin 9 further rotates in the a direction, the elastic body 8 is compressed and at the same time, the pin 13a of the pressure plate 13 is moved in the a direction (b in FIG. 8). At this time, the stopper 10 is in the arc groove 17 and the rotation wheel 12 can freely rotate with respect to the fixed wheel 14 (that is, the stopper 10 is in the non-operating state).
