In this case, by opening the auto stop switch SP, a slide open state in which the lid 1 is opened by a predetermined amount as shown in FIG. 8 is obtained. On the other hand, if the auto stop switch SP is not operated, the switching terminal S3 of the third detection switch LS-3 is switched to the idle contact ND, and the self-holding circuit QL is released. Can be

Next, in order to completely close from the slide open state, as shown in FIG.
The RS switch terminal S5 is switched to the closed contact a1. As a result, the relay coil R1 is excited, and the drive motor 7 is rotated forward by the current flowing from the first terminal 7a to the second terminal 7b.
5 returns to the neutral position, and the lid 1 can be fully closed.

On the other hand, when the lid 1 is tilted up, the switch terminal S5 of the slide operation switch SR-S
When one-touch operation is performed on the auto-open contact a2, the switching terminal S of the second detection switch LS-2 is switched as shown in FIG.
Since No. 2 has been switched to the normally open contact NO side, the slide open operation from the tilt-up ends in a swing, and the slide opening operation is prevented.
