Then, in a state in which the space between the display surface 51 of the display device 50 and the image transmission portion 31e of the fix 31 is opened, the cleaning worker moves the display surface 51 of the display device 50 and the image transmission portion 31e of the fix 31 apart. The display surface 51 of the display device 50 and the image transmitting portion 31e of the fix 31 are cleaned by, for example, wiping off dust adhering to the indoor surface 10e side of the display device 50 .

The cleaning operator manually opens the doors 21 and 22 in a state in which the display surface 51 of the display device 50 and the image transmitting portion 31e of the fix 31 are open, so that the image can be seen through the opening 10a. It is possible to go out to the outdoor 10f side, and after going out to the outdoor 10f side, it is also possible to clean the surface of the image transmitting portion 31e of the fix 31 on the outdoor 10f side.

After cleaning the display surface 51 of the display device 50 and the image transmitting portion 31e of the fix 31, the cleaning operator manually closes the doors 21 and 22 if they are open. 1, 3, 4 and 5, the cleaning worker rotates the display device 50 around the rotation axis 70a so that the display surface 51 of the display device 50 and the fix 31 are separated from each other. It closes the image transmitting portion 31e.

After closing the space between the display surface 51 of the display device 50 and the image transmission portion 31e of the fix 31, the cleaning worker changes the plane handle 75 from the state shown in FIG. 8 to the state shown in FIG. The display device 50 is fixed to the vertical frame 31b of the fix 31. As shown in FIG.

Finally, the cleaning operator initiates power supply to both drive unit 43 and control unit 44 . The automatic door system 10 can automatically open and close the doors 21 and 22 when power supply to both the drive unit 43 and the control unit 44 is started.

As described above, in the automatic door system 10, the fixing portion 70 supports the display device 50 so that the display surface 51 of the display device 50 and the image transmission portion 31e of the fix 31 can be opened and closed.
