At this time, the etching sheet is formed by adhering the release film to the back surface of the etching film.

The etching sheet fed to the discharge guide 650 is separated into an etching film and a release film (S112).

The etched film is guided by the discharge guide 650 and is fed to the glass via the cutting shears 660 and then pressed by the press roller 670 to be attached to the glass, and the release film is wound around the collecting roller (S114).

At this time, the advancing roller 640 stops rotating when the etched sheet is discharged by the advance roller 640 by a predetermined length, and the etched film guided to the cutting shears 660 by the discharge guide 650 is cut by the cutting shears 660, (S116).
