DETAILED DESCRIPTION OF THE INVENTION

(6) Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiment. FIGS. 1A and 1B show a film holder 10 consisting of a device for sticking a film on a display screen according to the present invention, and the film holder 10 shown in the drawings has a flat plate shape and has a protruding engagement piece 11 which is inserted into and fixed to a connector on the mobile device side, which serves as an engagement partner.

(7) The film holder 10 has a flat plate-shaped outer shape having an overall width substantially equal to the lateral width of a mobile device M, and a length in a longitudinal direction, which is shorter than the overall width. The mobile device M shown in the drawings has a longitudinally long form, and therefore, on the basis of the shape, a long side direction thereof is identified as the longitudinal direction and the direction orthogonal thereto is identified as the lateral direction, and the top and bottom and the right and left are defined on the basis of the long side direction.

(8) In the film holder 10, a portion corresponding to a lower side B of the mobile device M serves as a reference for positioning thereof with respect to a display screen D. Therefore, the film holder 10 is first positioned with respect to the mobile device M by bringing an upper side 12 thereof into contact with the lower side B. Therefore, in this position, small protrusion portions 13 and 14 which come into contact with the lower side B of the mobile device to define a position are provided on the upper sides 12 on both right and left sides with the engagement piece 11 interposed therebetween.

(9) For the same purpose, small protrusion portions 11a and 11b are also provided on both sides of a base portion of the engagement piece 11. Accordingly, the small protrusion portions 11a, 11b, 13, and 14 come into contact with the lower side B of the mobile device M, whereby the positioning of the film holder 10 with respect to the mobile device M is accurately performed (refer to FIG. 4B). Further, since the small protrusion portions 11a and 11b come into contact with the lower side B when the engagement piece 11 is inserted into a connector C on the mobile device side, the small protrusion portions 11a and 11b also serve as stoppers to limit the insertion.

(10) In the film holder 10, at least two positioning projections 15 and 16 are provided as one of positioning means 18. Further, in this embodiment, a third positioning projection 17 is provided. The third positioning projection 17 is located at a position that is disposed asymmetrically right-left in relationship with the two positioning projections 15 and 16.

(11) The positioning projections 15, 16, and 17 protrude from only one surface side of the film holder 10. Further, the positioning projections 15, 16, and 17 are disposed asymmetrically right-left, whereby the positional relationship between a film main body 20 and the film holder 10 is uniquely determined.

(12) Further, in this embodiment, as the other of the positioning means 18 for the film main body 20, the same number of positioning holes 21, 22, and 23 which are commensurate to the positioning protrusions 15, 16, and 17 are provided on the side of the film main body 20. In each of the drawings, reference numeral 19 denotes a film holding plate part, which has an opening portion 24 for handling the film holder 10.

(13) The film main body 20 has a three-layer structure (not shown) in which it has, on one side, a release layer attached to an adhesive layer which is stuck on the display screen D and has, on the other side, a skin layer for preventing damage to the film. Further, the film main body 20 has substantially the same size and shape as the display screen D, the positioning holes 21, 22, and 23 are located at an end portion in the longitudinal direction of the film main body 20, and the release layer is divided into two parts at an intermediate portion in the longitudinal direction.

(14) A method, of using the device 25 for sticking a film on a display screen according to the present invention, which is configured as described above, will be briefly described with reference to FIGS. 4A to 4C and the subsequent drawings. A user first wipes the display screen D of the mobile device M to remove dust or dirt (FIG. 4A). Subsequently, the engagement piece 11 is inserted into the connector C on the mobile device side.

(15) FIG. 3 also shows the process, and correct mounting can be confirmed by looking at the fact that the positioning projections 15, 16, and 17 of the inserted film holder 10 are present on the screen side. Next, the positioning holes 21, 22, and 23 are fitted to the positioning projections 15, 16, and 17. However, with this work, the small protrusion portions 11a, 11b, 13, and 14 come into contact with the lower side B of the mobile device M, the film main body 20 is superimposed on the display screen D of the mobile device M, and thus the positioning is correctly performed (FIG. 4B).

(16) The user peels off the upper half of a release layer 20a which is divided into two parts while visually confirming that the positioning of the film main body 20 has been already completed (FIG. 4C), and sticks the film 20b of the upper half on the display screen D. Subsequently, the user peels off the lower half of the release layer 20a which is divided into two parts (FIG. 5A) and sticks the film 20b of the lower half on the display screen D. Finally, in a case where air bubbles remain with the peeling-off of the release layer, the air bubbles are removed with a removing tool, whereby the work is finished (FIG. 5B).
