-Cabinet manufacturing method-Next, the manufacturing method of the back cabinet 2b of the mobile phone 1 will be described.

6 to 11 are views showing the order of manufacturing the synthetic leather cover 9 that covers the appearance of the first housing 2 .

First, the above-mentioned hook-and-loop fastener 19 is prepared (preparation process).

Next, as shown in FIG. 7, the first double-sided tape 43 is attached to the non-woven fabric layer side of the flat synthetic leather main body 30. The first double-sided tape 43 is adhered to the back surface side of the hook surface 16 of the flat surface fastener 19. In this way, the flat synthetic leather cover 9 is preformed (first pasting step).

Next, as shown in FIG. 10, the synthetic leather cover 9 in a state where the hook surface 16 and the synthetic leather main body 30 are adhered to each other is press-molded so as to have a curved surface while being heated (pressing step). That is, while heating the flat synthetic leather cover 9 of FIG. 7 with a press molding machine (not shown), unevenness is provided so as to have a curved shape of the first housing 2 (see the cross-sectional view taken along line XX). ). The corner portion 23 is also molded at the same time. In the molding of the corner portion 23, when only the synthetic leather main body 30 is press-molded, after removing it from the press molding machine, it is restored to almost a flat surface, and the effect of press-molding is reduced. By press-molding the thermoplastic resin sheet 50 of the hook surface 16 together, the shape of the press-molded mold is maintained. Since the thermoplastic resin sheet 50 is molded while being further heated to soften it, wrinkles grow and become inconspicuous from the appearance.

Next, as shown in FIG. 11, the curved synthetic leather cover 9 of FIG. 10 is cut into the outer shape of the shape of the first housing 2, and if necessary, a hole is punched (cutting step). ).

Next, as shown in FIG. 6, the loop surface 18 cut according to the back side cabinet 2b is attached to the back side cabinet 2b with the second double-sided tape 44 (second attachment step). At this time, since the loop portion 17 is formed on the soft non-woven fabric 51 on the loop surface 18, it is easy to follow the curved surface and wrinkles are unlikely to occur.

Next, as shown in FIG. 8, the synthetic leather cover 9 is attached to the back cabinet 2b by engaging the hook surface 16 of the synthetic leather cover 9 with the loop surface 18 of the back cabinet 2b (cover attachment step). ).

Finally, as shown in FIG. 9, the outer cut end of the synthetic leather cover 9 is covered with the decorative ring 10 by inserting the locking claw of the decorative ring 10 into the locking hole of the back cabinet 2b. (Finishing process). As a result, the back side cabinet 2b of the first housing 2 shown in FIG. 10 is completed (see the sectional view taken along line YY).

-How to change the synthetic leather cover-Next, how to change the synthetic leather cover 9 will be explained.

First, the locking claw of the decorative ring 10 is removed from the locking hole of the back cabinet 2b, and the decorative ring 10 is removed.

Then, while peeling off the synthetic leather cover 9, the hook surface 16 is disengaged from the loop surface 18 of the back cabinet 2b.

A new synthetic leather cover 9 is then prepared and its hook surface 16 is engaged with the loop surface 18 of the back cabinet 2b.

Finally, the locking claw of the decorative ring 10 is inserted into the locking hole of the back cabinet 2b to complete the dressing.

-Effect of Embodiment 1- As described above, since the synthetic leather main body 30 is not attached to the back side cabinet 2b by insert molding, the unevenness of the surface of the synthetic leather main body 30 is not crushed, and the original softness of the synthetic leather main body 30 is maintained. Is maintained. Since the synthetic leather cover 9 is attached to the back cabinet 2b with a removable hook-and-loop fastener 19, the synthetic leather body 30 can be changed. Since the decorative ring 10 covers the outer cut of the synthetic leather cover 9, the misalignment of the outer cut of the product is hidden and the appearance is good.

Further, since the hook surface 16 contains the thermoplastic resin sheet 50 in advance, the thermoplastic resin sheet 50 maintains its curved surface shape by applying heat to the hook-and-loop fastener 19 itself and molding it according to the curved surface of the product. Therefore, it is easy to change clothes.

Further, in the first sticking step, the loop surface 18 and the back side cabinet 2b are stuck with the first double-sided tape 43, so that the loop portion 17 on the surface of the loop surface 18 is not subjected to the molding pressure unlike the insert molding. Since it is not crushed, the joint strength of the hook-and-loop fastener 19 does not decrease.

In the second sticking step, the hook surface 16 and the synthetic leather main body 30 are firmly bonded to each other by sticking the hook surface 16 and the synthetic leather main body 30 with the first double-sided tape 43.

In the above finishing process, the decorative ring 10 is detachably claw-fitted to the back cabinet 2b, so that the decorative ring 10 can be easily attached and detached. It is possible to cover the outer cut end of the made cover 9.

Since the electronic device is a mobile communication device such as a mobile phone 1, the mobile communication device is often carried when going out, and there is a strong need to change clothes according to the usage situation, and it is operated by hand. In many cases, the feel of the synthetic leather body 30 is preferred, so that the effects of the present embodiment are remarkably exhibited.

-Modification Example 1-In the first embodiment, the hook surface 16 is adhered to the synthetic leather cover 9 side with the first double-sided tape 43, and the loop surface 18 is attached to the base material 20 side with the second double-sided tape 44. On the contrary, the loop surface 18 may be adhered to the synthetic leather cover 9 side with the first double-sided tape 43, and the hook surface 16 may be adhered to the base material 20 side with the second double-sided tape 44.

In this case, the loop surface 18 is composed of a plurality of loop portions 17 provided on the surface of the thermoplastic resin sheet 50, and the hook surface 16 is formed of a plurality of hook portions 15 formed on a soft non-woven fabric 51. You can use it.

-Modification Example 2-The back side cabinet 2b may be formed by insert molding the loop surface 18 and the plastic resin. For example, although not shown, the loop surface 18 is attached so that the loop portion 17 side abuts on the molding surface of the lower mold of the injection molding mold. Then, the upper mold is closed to form a cavity. The molten resin is poured into this cavity, and by injection molding, insert molding is performed so that the loop surface 18 is attached on the base material 20. At this time, by increasing the thickness of the non-woven fabric 51 layer on the loop surface, it is possible to prevent the loop portion 17 from being crushed.

By doing so, the trouble of adhering the back side cabinet 2b and the loop surface 18 is saved, and both are firmly adhered to each other.

-Modification example of Embodiment 1 3-The loop surface 18 and the back side cabinet 2b may be attached with an adhesive applied to the back surface of the loop surface 18. By doing so, the second double-sided tape 44 is not required, and the hook portion 15 or the loop portion 17 on the surface of the loop surface 18 is not crushed by the forming pressure as in insert molding, so that the bonding strength of the hook-and-loop fastener 19 is lowered. In addition, the bonding work is easy.

Further, the hook surface 16 and the synthetic leather main body 30 may be attached with an adhesive applied to the back surface of the hook surface 16. By doing so, the first double-sided tape 43 is not required, and the hook surface 16 and the synthetic leather main body 30 can be adhered to each other extremely easily.

(Embodiment 2) FIG. 12 shows the second embodiment of the present invention, in which the hook surface 116 is not provided with a plurality of hook portions 15 on the surface of the thermoplastic resin sheet 50, but is provided on a soft material such as a non-woven fabric 51. This is different from the first embodiment. In each of the following embodiments, the same parts as those in FIGS. 1 to 11 are designated by the same reference numerals, and detailed description thereof will be omitted.

Specifically, the synthetic leather cover 9 is press-molded so as to have a curved surface while being heated while the hook surface 116 of the hook-and-loop fastener 19, the thermoplastic resin sheet 21, and the synthetic leather main body 30 are adhered to each other. Is cut. The thermoplastic resin sheet 21 is made of polypropylene, nylon, polyester or the like.

The hook surface 116 and the thermoplastic resin sheet 21 are attached by the first double-sided tape 43. The thermoplastic resin sheet 21 and the synthetic leather main body 30 are attached with a first double-sided tape 43.

-Cabinet Manufacturing Method-Next, the manufacturing method of the back side cabinet 2b covered with the removable synthetic leather cover 9 according to the present embodiment will be described only for the portion different from the above-described first embodiment.

First, the hook-and-loop fastener 19 according to the present embodiment is prepared (preparation step).

Next, the hook surface 116 and the thermoplastic resin sheet 21 are adhered with the first double-sided tape 43, and the thermoplastic resin sheet 21 and the synthetic leather main body 30 are adhered with the first double-sided tape 43 (first sticking step).

Then, the same steps as in the first embodiment are performed.

-Effect of the second embodiment- Therefore, also in this embodiment, since the synthetic leather main body 30 is not attached to the back side cabinet 2b by insert molding, the unevenness of the surface of the synthetic leather main body 30 is not crushed, and the synthetic leather main body 30 is not crushed. The original softness of the product is maintained. Since the synthetic leather cover 9 is attached to the back cabinet 2b with a removable hook-and-loop fastener 19, the synthetic leather body 30 can be changed. Since the decorative ring 10 covers the outer cut of the synthetic leather cover 9, the misalignment of the outer cut of the product is hidden and the appearance is good.

Further, since the thermoplastic resin sheet 21 is adhered to the hook surface 16, heat is applied to the synthetic leather cover 9 and molded according to the curved surface of the product, so that the thermoplastic resin sheet 21 has the curved surface shape. Since it is kept, it is easy to change clothes.

-Modification Example 1 of Embodiment 2-Also, the hook surface 16 and the thermoplastic resin sheet 21 may be attached with an adhesive applied to the back surface of the hook surface 16. By doing so, adhesion between the hook surface 16 and the thermoplastic resin sheet 21 is extremely easy.

Further, the thermoplastic resin sheet 21 and the synthetic leather main body 30 may be adhered with an adhesive.

Other modifications similar to those of modifications 1 and 2 of the first embodiment can be considered.

(Embodiment 3) In the present embodiment, as the hook-and-loop fastener 119, a plurality of hook-and-loop fasteners 15 and loops 17 are mixed on each surface 119a.

Specifically, a plurality of hook portions 15 and loop portions 17 are mixed on one surface 119a of the hook-and-loop fastener 119, and a plurality of hook portions 15 and loop portions 17 are also mixed on the other surface (not shown). To use. As for other configurations, the configurations of the above-described first and second embodiments may be appropriately applied.

By doing so, the hook-and-loop fastener 119 itself feels good to the touch, and lint and dust are less likely to adhere to the surface fastener 119. Therefore, the durability is high, and it is possible to comfortably change clothes many times.

(Other Embodiments) The present invention may have the following configurations with respect to the above embodiment.

That is, in the above embodiment, the electronic device is the mobile phone 1, but it may be an electronic device such as a PC, a mobile tool, an electronic dictionary, a calculator, or a copier, or a mobile communication device such as a PHS or PDA.

It should be noted that the above embodiments are essentially preferable examples, and are not intended to limit the scope of the present invention, its applications and applications.
