  However, the decoration of the cover for a mobile phone in the above-described conventional example has a problem such as a sticker or paint peeled off. In particular, since mobile phones are held and operated by hand, they can be peeled off by perspiration, and can be rubbed off when stored in a pocket or bag or placed on a table, etc. It was difficult to do. Therefore, there is a problem in that the design is impaired during use, thereby increasing costs and labor, such as decorating again.

  For this reason, in the present invention, a mobile phone terminal capable of realizing a highly reliable decoration that can be maintained for a long period of time without peeling, improving design, and reducing the cost of the decoration. It is an object of the present invention to provide a decoration method for a cover.

  For this reason, the decoration method for the cover for a mobile phone terminal according to one aspect of the present invention is applied to the cover for the mobile phone terminal from the surface of the cover to 5 μm to 100 μm, and more preferably according to the coating thickness of the cover surface. It is characterized by being decorated by engraving with a depth of 10 μm to 50 μm. According to the present invention, since the engraving of the above depth is performed from the surface of the cover, even a thin mobile phone cover for small size and light weight is decorated by engraving without reducing the strength of the cover. be able to. And since it is a sculpture, there is no worry about peeling and the reliability of the decoration can be improved. Furthermore, since the depth of the sculpture is extremely shallow, the user can maintain the fit without feeling the rough feeling of the sculpture when the user carries it.

  Further, the sculpture is applied to a cover for a mobile phone terminal having a coating surface shallower than the sculpture depth. Thereby, for the cover whose surface is coated, by engraving to remove this coating, the portion located in the lower layer of the coating is exposed from the engraving portion, and the design can be improved.

  Furthermore, the engraving is performed on the cover for the mobile phone terminal that is detachable from the mobile phone terminal. At this time, the engraving is performed on the surface of the detachable mobile phone terminal cover on the mounting surface side to the mobile phone terminal. Thereby, since it can engrave with the cover removed, the degree of freedom of engraving increases. In particular, by engraving the surface located on the inner side of the cover, which is a transparent member, the decoration can be visually recognized from the outside while maintaining the shape of the terminal surface.

  In addition, the engraving is performed using a laser processing machine. Thereby, highly accurate engraving can be realized, which is suitable for the present invention.

  Since the present invention is configured and functions as described above, according to this, since the surface of the cover is engraved on the order of micrometers, even if the cover is for a small cellular phone, the cover is thin. It is possible to give decoration by engraving without lowering the strength of the material, and furthermore, there is no worry about peeling and the reliability of decoration can be improved.

  The method for decorating a cover for a mobile phone terminal according to the present invention is characterized in that the cover is decorated by engraving an extremely shallow depth on the surface of the cover. Hereinafter, a specific configuration will be described in Examples.

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a configuration of a mobile phone and its cover, and FIG. 2 is a diagram showing a state when engraving the cover.

  A mobile phone terminal 1 shown in FIG. 1A is a foldable mobile phone in which an upper housing 11 and a lower housing 12 are connected via a hinge so as to be rotatable. A cover 2 shown in FIG. 1B is detachably attached to the surface of the upper housing 11. The cover 2 can be replaced to change the design of the mobile phone terminal 1. And since this invention is the method of giving and decorating the surface of this cover 2, the cover 2 and its engraving method are explained in full detail below.

As shown in FIG. 1B, the cover 2 is a plate-like member having substantially the same outer shape as the upper housing 11 and a thickness of about 1.0 mm. Then, it shows a sectional view thereof in FIG. 2, a base portion 21 having a predetermined thickness H ₁ (base member), the thickness H which is applied to the surface of the cover 2 to be positioned outside of the mobile phone when worn _{2 includes} a coating portion 22 having a thickness of about 20 μm. For example, a single color such as red or blue or a predetermined pattern is applied to the coating portion 22. Or the coating part 22 is not limited to one layer, It is formed by the multilayer coating. Further, the thickness H ₂ of the coating portion 22 or the thickness of the coating layer located on the outermost surface forming the coating portion 22 is formed to be shallower than the engraving depth described later, for example, 5 to 100 μm. It is formed to a thickness, more specifically, a thickness of about 10 to 50 μm. In addition, the thickness of the whole cover 2 mentioned above, and the thickness of the base part 21 and the coating part 22 are an example, Comprising: It is not limited to the said thickness.

  The cover 2 is further engraved with characters and pictures as indicated by reference numeral 20 in FIG. In this figure, the character “DESIGN” is illustrated as an example of engraving, but is not limited to the character and may be a pattern or a picture. FIG. 2 shows a configuration for performing such engraving and a state during engraving.

  As shown in FIG. 2, engraving on the cover 2 is performed using a laser processing machine 3. The laser processing machine 3 includes a laser irradiation device 31 that irradiates the surface of the cover 2 placed on the work table G with a laser beam 31a for engraving, a drive device 32 that drives the position of the laser irradiation device 31, And a controller 33 for controlling the laser irradiation position and the irradiation output. The laser irradiation device 31 outputs a predetermined beam system (for example, 30 μm) and a laser beam having a predetermined intensity in accordance with a control command from the controller 33.

  In particular, the intensity of the laser beam may be set to an intensity at which engraving with a depth of 5 μm to 100 μm, desirably 10 μm to 50 μm from the surface of the cover 2. That is, it is desirable to have a strength that removes the coating portion 22 of the cover 2. Or in the case of the coating part 22 which consists of a multilayer, the intensity | strength of the grade which removes the predetermined layer formed in the surface side may be sufficient. As a result, by engraving to remove the coating portion 22 on the surface, the background (for example, metal color) of the base portion 21 of the cover located in the lower layer of the coating is exposed from the engraving portion to further decorate the engraving portion. It is possible to improve the design. Furthermore, when the coating is a multilayer, the color of the lower layer of the removed layer is exposed to the outside, and the engraving portion can be decorated.

  The engraved cover 2 is attached to the surface of the upper housing 11 of the mobile phone terminal 1 with screws or the like. By doing so, the surface of the cover is decorated with sculptures on the order of micrometers, so even if it is a thin cover for a mobile phone to reduce the size and weight, the strength of the cover is not reduced. Can be decorated with sculpture. And since it is a sculpture, there is no worry about peeling and the reliability of the decoration can be improved. Furthermore, since the depth of the sculpture is extremely shallow, the user can maintain the fit without feeling the rough feeling of the sculpture when the user carries it. In addition, since engraving is performed using the laser processing machine 3, high-precision engraving of the micrometer order as described above can be realized.

  Here, the case where engraving is performed on the cover 2 that is detachable from the mobile phone terminal 1 is described above, but the surface of the housing may be directly engraved and decorated. Further, the configuration of the mobile phone 1 is not limited to the above-described folding type.

  Moreover, although the case where engraving was given to the cover 2 in which the coating part 22 was formed in the above was illustrated, it is not limited to this. Engraving may be performed on the cover 2 that has not been painted. The material of the cover 2 may be a metal member such as aluminum, or may be made of transparent acrylic or wooden. And the decoration by the unevenness | corrugation of a sculpture can be given by engraving the surface. In particular, by performing laser engraving on the acrylic cover 2, the engraved portion irradiated with the laser changes from transparent to white, thereby making the engraved portion stand out.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3A is a plan view showing the cover 4 in this embodiment, and FIG. 3B is a cross-sectional view taken along the line AA.

  As shown in this figure, the cover 4 that can be attached to and detached from the mobile phone terminal in this embodiment is substantially the same in shape as that described in the first embodiment. However, in this embodiment, the cover 4 is portable. The difference is that engraving is performed on the mounting surface side with the telephone terminal 1. Details will be described below.

  The cover 4 in the present embodiment is made of transparent acrylic, for example. Then, as shown in FIG. 3 (b), not the surface side 4A (external surface side) positioned outside when mounted on a mobile phone, but the surface of the mobile phone mounting surface side 4B (inside) Is given. The depth of the engraving is 5 μm to 100 μm as described above, and the engraving is executed by the laser processing machine 3. Then, the portion engraved by laser irradiation changes from transparent to white. Thereby, since the cover 4 is made of transparent acrylic, the engraving portion can be visually recognized from the outer surface side 4A on the opposite side. Then, the engraved mounting surface side 4 </ b> B is mounted facing the mobile phone terminal 1.

  By doing as mentioned above, since the engraving part is located inside, the engraving part can be protected. Moreover, there is no unevenness | corrugation in the outer surface side 4A, and it can suppress that a user's fitting feeling is impaired.

  According to the present invention, the cover of the mobile phone terminal can be decorated with engraving, the user's satisfaction can be improved, and there is industrial applicability.
