In addition, the second relay terminal r ₂ is the second relay coil R
_When a current flows through ₂ and is excited, it becomes possible to switch from the ground contact a ₁ to the open contact a ₂ connected to the power supply circuit BL.
When the current stops flowing through the relay coil R ₂ , the ground contact a
It is supposed to return to ₁ . The normally open contacts NO of the first and second detection switches LS ₁ and LS ₂ are grounded.

Among the first and second relay coils R ₁ and R ₂ , the first relay coil R ₁ is the first contact t ₁ of the operation switch ST connected to the power supply circuit BL, and the second relay coil R ₂ is the operation switch S.
The second contact t _{2 of} T is connected to the operation switch ST.

Next, regarding operation, in the neutral state, the lid 5 is fully closed in FIG. 1, the operation switch ST is in the neutral position, and the first and second relay terminals r ₁ and r ₂ are connected to the ground contact a.
_First , the switch terminals S ₁ and S ₂ of the first and second detection switches LS ₁ and LS ₂ are located on the side of the normally closed contact NC, and the motor 11 is off. Further, the protrusion 49B of the control disk 49 and the intermediate operating arm 55 are in the operating state. However, since the operation switch ST is in the neutral position, the pressing body 61 is retracted, and the intermediate operation arm 55 is in the idling state.

In the neutral state, in order to tilt up the lid 5, the operation switch ST is moved to the second contact t ₂ as shown in FIG.
When operated to the side, the second relay coil R ₂ is excited and the second relay terminal r ₂ is switched to the open contact a ₂ . This allows
A current flows from the motor terminal 11b to the motor terminal 11a, and the drive motor 11 rotates forward. Control disk 49 at the same time

The second detection switches LS ₁ and LS ₂ are turned on and switched to the normally open contact NO, the drive motor 11 is braked and the lid 5 is fully closed.

Next, in order to slide the lid 5 to the fully open state, the operation switch ST is operated to the first contact t ₁ side as shown in FIG. 8, the first relay coil R ₁ is excited, and the first relay terminal r ₁ becomes The contact is switched to the open contact a ₂ . Thus, the driving motor 11 is current from the motor terminal 11a to the motor terminal 11b flow projections 49A of the reverse rotation control disk 49 comes into contact with the upper operating arm 53, to press the switch terminal _{S 2} of the second detection switch LS _2. Therefore, the second detection switch LS ₂ is turned on, the contact is switched to the normally open contact NO, the drive motor 11 is braked, and the lid 5 is fully closed. In this case, the pressing body 61 is advanced by turning on the solenoid 65, but the projection 49B is not pressed because it has not reached the operating position. Hereinafter, in order to return the lid 5 to the fully closed state, the drive motor 11 is rotated in the forward direction by operating the switch ST to the second contact t ₂ side as shown in FIG.
The fully closed state of can be obtained.

Next, when the operation switch ST is in the neutral position and the lid 5 is tilted up, as shown in FIG.
Is closed, a current flows through the first control circuit GL and the first relay coil R ₁ is excited. At the same time, the third relay second terminal r ₃ -2 is opened and the solenoid 65 is turned off. On the other hand, from the motor terminal 11a to the motor terminal 11
The drive motor 11 rotates in reverse due to the current flowing in b. As a result, the lid 5 continuously operates from the fully closed state until the slide is fully opened. In this case, when the lid 5 is fully closed,
Since the solenoid 65 is off, the control disk 49
Causes the current to flow in the motor circuit ML to be secured. Next, when the slide is fully opened, the control disk 4
The switch S ₂ of the second detection switch LS ₂ is switched to the normally open contact NO by 9 so that the fourth relay coil R ₄ is excited and the fourth relay coil terminal r _{4 of} the first control circuit GL is opened. As a result, the second detection switch L
S ₂ is turned on, the contact is switched to the normally open contact NO, the drive motor 11 is braked, and the lid 5 is fully opened. It should be noted that the fully closed state can be achieved by operating the operation switch ST to the second contact t ₂ side as shown in FIG.
