It is a perspective view which shows the process of attaching a sticking apparatus to a terminal device. It is a side view which shows the state which the sticking apparatus is attached to a terminal device. It is a drawing which shows one form of a temporary fixing pin.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is an overall plan view of the protective film affixing device of the present invention. In the figure, 1 is a release film divided into 1a and 1b at a substantially central portion, and 2 is a protective film attached to a fixed position on the upper surface of the release film 1.

In the embodiment of the drawing, the protective film 2 has a shape corresponding to the display screen 8 of the terminal device S described later.

In the present invention, a bent portion 3 having a substantially end face width (thickness width) of the terminal device S is formed at one end of the release film 1. In the figure, reference numeral 4 is a partially cut line formed to facilitate bending of the bent portion 3. Further, a through hole 6 is formed at a position corresponding to the terminal port 5 formed on the end surface (periphery) of the terminal device S at substantially the center of the bent portion 3.

In the figure, reference numeral 7 is a temporary fixing pin, which is inserted into the terminal port 5 of the terminal device S through the through hole 6 of the release film 1 to position the release film 1 and the protective film 2 on the terminal device S.

Here, the opening 6 of the through hole of the release film 1 is formed in a shape different from the shape of the terminal port 5 of the terminal device S.

The opening of the through hole 6 of the release film 1 has a shape in which a commercially available charging connector (“Lightning” or “USB Type-C”) cannot be inserted (or is difficult to insert) (the release film 1). The shape of the opening of the through hole 6 is different from that of a commercially available connector.

Specifically, it is formed in a shape smaller than the shape of a commercially available connector. The shape of the opening of the through hole 6 of the release film 1 may be any shape as long as a commercially available charging connector cannot be inserted, and may be, for example, a star shape.

Here, the temporary fixing pin 7 is formed in a shape that can be inserted into the opening of the through hole 6 of the release film 1 (the shape of the temporary fixing pin 7 may be the same as the opening of the through hole 6). , The shape of the opening of the through hole 6 may be different as long as it can be inserted into the opening of the through hole 6).

Therefore, if the temporary fixing pin 7 is used, the release film 1 and the protective film 2 can be positioned on the terminal device S through the opening of the through hole 6 of the release film. (Since a commercially available charging connector cannot be inserted into the opening of the through hole 6 of the release film, the release film 1 and the protective film 2 cannot be positioned on the terminal device S through the opening of the through hole 6.).

Further, when the temporary fixing pin 7 is formed in a shape different from the opening 6 of the through hole of the release film 1, the temporary fixing pin 7 is inserted into the opening 6 of the through hole of the release film 1. Occasionally, the temporary fixing pin 7 may easily come off from the opening 6 of the through hole of the release film 1.

In order to prevent this, the temporary fixing pin 7 may be provided with a notch 9 (see FIG. 4).

In the method of attaching the protective film of the present invention, as shown in FIG. 2, the release film 1 obtained by attaching the protective film 2 to a fixed position on the upper surface and being divided is superposed on the display screen 8 of the terminal device S. The bent portion 3 formed at one end is bent to the end face of the terminal device S, and a temporary fixing pin 7 is inserted into the terminal port 5 of the terminal device S from the through hole 6 of the release film 1 as shown in FIG. The release film 1 and the protective film 2 are positioned on the terminal device S.

After that, the divided release film 1a on the opposite side of the temporary fixing pin 7 is peeled off from the protective film 2, and the protective film 2 is attached to a fixed position on the display screen 8 of the terminal device S.

Subsequently, the divided release film 1b on the temporary fixing pin 7 side is peeled off from the protective film 2 and the protective film 2 is attached to the display screen 8 of the terminal device S.

When the release film 1b on the temporary fixing pin 7 side is peeled off, the temporary fixing pin 7 is pulled out. In that case, since the release film 1a on the opposite side is already attached to the display screen 8 of the terminal device S, there is no possibility of misalignment, wrinkles, or bubbles.
