FIG. 4 is a development view of the first cam groove 30, and FIG. 5 is a development view of the second cam groove 31. The first cam groove 30 rotates the first lever 20 to the connector connecting position when the first roller 22 is positioned on the top 32a of the protrusion 32, and the first cam groove 30 moves from the top 32a of the protrusion 32 to the top. When the first roller 22 is detached, the first lever 20 is rotated toward the first frame 1 side to separate the first connector 7a from the second connector 7b. , Two semi-circular cam groove portions 33a and 33b having different radii are connected to each other, and when the cam groove portion 33a having the smaller radius is switched to the cam groove portion 33b having the larger radius, the second lever 21 in FIG. The third connector 7c is switched to the engagement / disengagement position of the first connector 7a by moving it to the front side (left side when viewed from the first frame 1 side), and in the opposite case, the second lever 21 is moved from the front side thereof. Back side (1st frame 1 side Look al adapted to switch the second connector 7b is disengaged positions of the first connector 7a is moved to the right). Here, the connector connection position of the first cam groove 30 (the connection position of the first connector 7a and the second connector 7b, the connection position of the first connector 7a and the third connector 7c) is 0 ° at the rotation angle of the rotary cam 5. And 180 °, and the switching timing (left movement, right movement) of the second cam groove 31 is set to positions of approximately 90 ° and 270 °.

When the rotation of the rotary cam 5 advances to the position where the rotation angle is 180 °, the first roller 22 of the first lever 20 reaches the switching point with the convex portion 32 again, and moves the connector connection base 2 in the connector connection direction. Then, the first connector 7a and the third connector 7c are completely connected at the position where the rotation angle is 180 °. Since the position where the rotation angle is 180 ° is the position where the first photosensor PH1 detects the first depression 34 and turns off, the contact 1x of the control circuit turns off and the contact 3x turns off at this position. The motor 6 automatically stops.

After stopping the drive motor 6, the line is removed, and after the line exchange is completed, the position of the rotary cam 5 is restored. At the time of restoration, since the position of the second depression 35 is located 180 ° before (on the retard side) the first optical sensor PH 2, the second optical sensor PH 2 is turned on, and the connector restoration line is used. The relay 4x is turned on. When the restoration first push button switch PB2 is turned on, the drive motor 6 is turned on and the drive motor 6 rotates. As a result, the first roller 22 of the first lever 20 starts descending from the convex portion 32 to start disconnection of the first connector 7a and the second connector 7b, and when the convex portion 32 descends. Complete the disconnection. When the rotation angle of the drive motor 6 advances to the 270 ° position, the third roller 29 of the second lever 21 reaches the switching position from the cam groove portion 33b having a large radius to the cam groove portion 33a having a small radius, and the cam groove portion having a small radius. When it is switched to 33a, the rightward movement of the second lever 21 is completed. As a result, the connector switching base 3 is moved to a position where the second connector 7b can be attached. When the rotation angle of the rotating cam 5 advances to the position of 360 °, the second photosensor PH2 detects the second depression 35 at this position and turns off. Therefore, the contact 2x and the contact 4x of the control circuit are turned off and the drive motor 6 is automatically stopped.
