DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to the structure of electronic equipment, and particularly to a structure suitable for application to the surface of a keyboard section of a small electronic equipment such as a calculator.

[Prior art]

The surfaces of various electronic devices are decorated with various symbols, marks, and in some cases, designs that suit the tastes of consumers. These symbols are applied to the sides and bottom of the device as appropriate, and various patterns are applied to the surface including the keyboard section along with the Φ- symbol.

These symbols and designs are generally applied to surface sheets that are attached to the surface of the device, and in conventional technology, designs are printed in color on metal sheets (such as decorative boards) or polyethylene sheets, and then applied to predetermined areas such as the surface of the keyboard. was attached to the entire surface with adhesive.

However, in such a conventional structure, it is necessary to form an adhesive layer on the printed sheet or the surface of the device and then affix the sheet, which poses a problem in that forming the adhesive layer requires time and effort.

Furthermore, in addition to key symbols and model indications, the sheets are now decorated with various designs that suit the tastes of consumers, as electronic devices have become personal items. However, with conventional printing methods, it is necessary to prepare a number of printing plates corresponding to the number of colors, and although it is suitable for mass production of the same design in a factory, it is necessary to prepare printing plates corresponding to the number of colors. It is not suitable for lot production (including one piece) and has the problems of high costs and long delivery times.

〔the purpose〕

The purpose of the present invention is to solve the problems of such conventional structures,
It is possible to easily provide a product with a pattern according to the taste of the consumer, and also to provide an electronic device that can reduce the number of man-hours required for sheet pasting when a pattern is applied on a production line.

[Summary]

The present invention uses photographic paper with an adhesive layer in the middle, and after or before forming a photographic image, the image layer and the adhesive layer are peeled off from a mount, and this is pasted on the surface of a device to form a pattern. By doing so, the purpose of the book is achieved.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, the case where the present invention is applied to a card or notebook type calculator will be specifically explained with reference to the drawings.

FIG. 1 shows the front side of a calculator 1, which is the surface that includes the keyboard section of an electronic device.A key symbol 2 and a pattern 3 are applied to the surface, and a window is also provided on the calculator display section 4 and the solar cell light receiving section 5. is formed.

FIG. 2 shows the cross-sectional structure of the keyboard part of the E-note calculator 1,
A spacer 8 of a certain thickness is sandwiched between the circuit board 6 on which the circuit is printed and the hill cover 7, and an opening 9 is formed in the spacer 8 at a position corresponding to each key symbol 2. A contact support member 11 having a movable contact 10 is inserted. A fixed point 12 is formed at a position on the substrate 6L facing the movable contact 10. The cover 7 and the contact support member 11 are made of an elastically deformable material (plastic), and when pressed in the direction of arrow P with a fingertip, they elastically deform to bring the movable contact 10 into contact with the fixed contact 12 and complete a predetermined circuit. It is configured to close.

A photographic image layer 15 consisting of an aluminum layer 13 and an emulsion layer 14 is attached to the L side of the upper cover 7 via an adhesive layer 16.

The image layer 15 and adhesive layer 16 are peeled from the photographic paper shown in FIG.

That is, the photographic paper in FIG. 3 includes a mount 17 and an adhesive layer 16.
, has a cross-sectional structure in which an aluminum layer 13 and an emulsion layer 14 are sequentially bonded, and is formed so that it can be peeled off between an intermediate adhesive layer 16 and a mount 17. Therefore, this adhesive layer 16
By peeling off, it is possible to separate the mount portion and the sheet portion having the image layer 15 and the adhesive layer 16.

By attaching this separated sheet portion to the upper cover 7, the surface structure of the electronic device (calculator) 10 shown in FIGS. 1 and 2 is obtained.

Note that image formation (printing) on photographic paper is usually performed before peeling off, but in some cases, image formation may be performed after peeling off and pasting 9 on the surface of an electronic device.

The aluminum layer 13 is a layer suitable for strengthening the hiding power and forming an extremely thin and highly flexible top sheet that does not expand or contract and does not absorb moisture.

Further, the photographic paper has a predetermined shape (in the illustrated example, the plane shape of the calculator 1 ) and no-fukatsu)18(
3) are preformed. Similar half cuts are also formed in advance in portions corresponding to the windows (openings) of the liquid crystal display section 4 and the solar cell light receiving section 5.

According to the embodiment described above in FIGS. 1 to 3, the pattern of the top sheet is formed using a photograph according to the consumer's preference, so there is no need to produce a printing plate such as inkuri, and the pattern is hand,
To easily and quickly provide products with desired designs to various tastes at low cost.

In addition, since the adhesive layer 16 provided between the photographic paper and the mount 17 can be used as it is to attach it to the surface of the device, the adhesive application process is no longer necessary, resulting in a reduction in man-hours. can get.

Furthermore, since the pattern is formed using a photograph, it is possible to easily form a clear and accurate pattern without any color fading unlike in printing.

FIG. 4 is a diagram showing another example of the structure of photographic paper. In this case, the image layer 1 which constitutes the top sheet together with the adhesive layer 1B
A polyethylene layer 19 is added to 5, and the other structure is the same as in FIG.

This polyethylene layer 19 not only imparts appropriate rigidity to the top sheet, but also strengthens the adhesive force with the adhesive layer 16 to eliminate the possibility that the adhesive layer 16 remains on the mount 1T side when peeled off. It is something.

It should be noted that various other structures may be adopted as the structure of the photographic paper, for example, a structure may be adopted in which a paper layer or a polyethylene layer is used in place of the aluminum layer 13 in FIG.

Further, in the embodiment described above, the present invention was applied to the surface of the keyboard section, but the present invention can also be freely implemented to the back side (bottom surface) or side surface of the device.

〔effect〕

As is clear from the above description, according to the present invention, an adhesive layer is provided in the middle of the photographic paper forming the photographic image (design),
Since the sheet portion peeled off from the mount is attached to the surface of the device to provide a pattern, it is possible to easily and quickly provide electronic devices with patterns that match the preferences of a wide variety of consumers.
