7 is reversed and the double chain 54 is reversed.
9 to P1 are transferred toward the storage rails 8 and 9.

Simultaneously with the activation of the drive motor 37, the first stop device 57 is activated and the stopper 63 is moved down between the first runner 15 of the final panel P and the second runner 28 of the succeeding panel P8. The second runner 28 of P8 is stopped by the stopper 63, and therefore the panels P8 to P1 are stopped.

The driven second runner 28 of the final panel P9 that is transferred in the storage direction first is guided to the second storage rail 9, and when the first runner 15 approaches the intersection C1, the second runner 28
This activates the limit switch 67, which activates the first stop device 57, moves the stopper 63 upward, and moves the second and subsequent panels P8 to P1 in the storage direction again.

When the stopper 63 of the first stop device 57 is moved upward, the limit switches 64 and 65 cause the stopper 63 to move upward.
3 is automatically moved down and stopped, so the third panel P7 is stopped, and when the second panel P8 operates the limit switch 67, the stopper 63 is moved up again and the third and subsequent panels P7 to P1 is moved.

Thereafter, the above-described panel storage operation is sequentially repeated, and the panels P7 to P1 are smoothly stored one by one in the storage rails 8 and 9 at regular intervals without interfering with each other, and the opening of the door is completed.

Now, in the first embodiment of the present invention, nine pairs of first and second runners 15 for hanging panels are supported along the main banger rail 7 and the first and second storage rails 8 and 9 in a reciprocating manner. .28, the panels P1 to P9 are each suspended, and the upper chain 54b of the double chain 54 is engaged with the sprocket wheel 21 of the first runner 15 to convey each panel.
