[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mouse pad used with a mouse for moving a cursor on a CRT or a liquid crystal display of a personal computer or the like. More specifically, the present invention relates to a mouse pad for use with an optical mouse.

[0002]

[Prior art]

 In recent years, optical mice have begun to be used as input devices for computers and the like, and are expected to become more widespread in the future. This optical mouse has, as its basic structure, a light emitting unit, a light receiving unit, and a moving amount determining unit.

On the other hand, a conventional mouse pad used for an optical mouse is provided with a white high-reflection portion and a black low-reflection portion, and the light emitting portion emits light depending on the position of the optical mouse on the mouse pad. Part or all of the received light is reflected and reaches the light receiving unit. Then, a change in current occurs in the optical mouse according to the presence or absence and the degree of light reception by the light receiving section, and this change is input to the computer as a movement amount of the optical mouse.

[0004] In order to give such a mouse pad for an optical mouse a warm and pleasant impression, for example, Japanese Patent Application Laid-Open No. 10-320110 discloses a method of providing a colored layer constituting a colored pattern and providing a picture using various colors. A mouse pad for an optical mouse showing a design is disclosed. However, according to this technology, pictures and designs can certainly be represented on a mouse pad, but the colored layer must have a high transmittance and a predetermined color tone in at least a part of the visible region. (Transparent color) is required, and there is a problem that there is a limitation on design selection by a user.

In particular, with the spread of bubble jet and laser type color printers, personal computer users can freely operate and obtain color images (including photographs), and the design materials are increased. Considering that it is becoming more and more abundant, it can be said that it is desirable to increase the degree of freedom in selecting mouse pad designs.

[Problems to be solved by the invention]

 Accordingly, an object of the present invention is to solve such a problem and to provide a mouse pad for an optical mouse using a color-printed photograph.

[0007]

[Means for Solving the Problems]

 The present invention is characterized by comprising a substrate, a photograph printed on the substrate in color, and a transparent resin sheet covering the photograph, wherein the photograph has a mesh-like white lattice at least on the transparent resin sheet side. And a mouse pad for an optical mouse. In this mouse pad, the white grid is formed of grids having the same vertical and horizontal lengths, and the pitch of the parallel lines constituting the white grid is 0.70 to 0.80 mm and the thickness is 0.06 to 0.06 mm. It is effective that it is 0.10 mm.

Further, it is effective that the transparent resin sheet is made of polyethylene terephthalate. Further, the base material has release paper on a surface opposite to the color photograph side via a non-adhesive release layer, and the mouse pad is post-posted by using the surface of the release paper. It is also effective to function as a card.

[Embodiment of the invention]

 The present inventor thought that if color-printed photographs could be used for an optical mouse mouse pad, there would be more room for the user to select a mouse pad design, and a colorful and unique mouse pad could be provided. However, in the conventional mouse pad for an optical mouse, simply printing a color on a printing surface did not move the cursor on the computer screen correctly, and the optical mouse could not function properly. This is because the optical mouse does not reflect the photo because it is not composed of single colors that are clearly painted, and there are many parts where the boundaries between colors are blurred and the colors move naturally. This is probably because the difference in light intensity cannot be detected accurately.

On the other hand, the present inventor has conducted intensive studies on how to realize a mouse pad for an optical mouse using a color photograph. The inventor found that if a fine mesh-shaped white grid was provided on the entire surface of the photo by time of operation, the optical mouse could be used as usual without losing the design of the photo, and the present invention was completed. That is, the present invention comprises a base material, a color-printed photo of the base material, and a transparent resin sheet covering the photo, wherein the photo has a mesh-like white lattice at least on the transparent resin sheet side. It is related to a mouse pad for an optical mouse. Hereinafter, the mouse pad according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic top view of one embodiment of a mouse pad for an optical mouse according to the present invention, and shows the configuration of a color photographic layer. FIG. 2 is a partially enlarged view of the mouse pad shown in FIG. 1, and FIG. 3 is a schematic vertical sectional view for explaining a layer structure of the optical mouse mouse pad according to the present invention.

The main feature of the present invention is that, as shown in FIG. 3, a color photographic layer 1 printed on a base material 3 and disposed between the base material 3 and the transparent resin sheet 4 is provided. The point is that at least the transparent resin sheet 4 side, that is, the surface on the side in contact with the optical mouse has the mesh-shaped white lattice 2 (see FIG. 1). Preferably, the color photographic layer 1 has a white grating 2 on all sides. In FIG. 1, the substrate and the transparent resin sheet are omitted, and the color of the color photograph portion 1 'is also omitted. Also, in order to clearly explain the present invention, the dimensions of the white grid are larger than the actual size.

Since the white grating 2 has a high reflectance, even if a color-printed photograph is composed of various colors, the optical mouse can move the white grating portion 2 ′ and the color photograph portion 1 ′ according to the position. The difference in the reflected light at is always detected. For these reasons, the mouse pad of the present invention is considered to be applicable to an optical mouse. Furthermore, light of various colors is used as light emitted from the light emitting portion of the optical mouse. However, the mouse pad of the present invention can be applied to an optical mouse using light of any color without knowing the detailed reason.

The white grating 2 may be formed by forming the color photographic layer 1 in a grid-like shape, with a white portion of the substrate exposed on the surface. The white grid 2 may be further printed on the color printing surface of. Specifically, it is preferable to form the color photographic layer 1 by, for example, offset printing. In addition, it is theoretically possible to print a color photograph as usual and then attach a white mesh-like grid on top of it. When an image is printed as a photograph from a personal computer or the like using a laser printer or the like, it is also possible to print the image after processing the image with the white lattice 2 on the computer.

Next, as a result of examining the shape of the white grid 2, from the viewpoint that the cursor can be moved normally, the grid shape is a grid (square) having the same vertical and horizontal length. Was found to be preferable. The optical mouse detects a difference in reflected light between the white parallel line portion and the photographic portion 1 ′ of the color photographic layer 1 when passing through the white parallel line constituting the white grid 2, and corresponds to the interval. Is set to the moving distance of the cursor. Therefore, if the white parallel lines are arranged at equal intervals in the vertical and horizontal directions, the mobility of the cursor is constant in the vertical and horizontal directions.

Further, from the viewpoint that the cursor on the screen can be moved more smoothly and accurately by moving the optical mouse, the inventor of the present invention has proposed the pitch of the white parallel lines constituting the white grating 2. Of 0.70 to 0.80 mm and a thickness of 0.06 to 0.10 mm are effective. Here, FIG. 2 is a partially enlarged view of FIG. As shown in FIG. 2, the color photographic layer 1 is provided with a white grid 2 composed of white parallel lines having a pitch X (mm) and a thickness Y (mm). When an optical mouse (M-GUWSRSV) manufactured by ELECOM was used, it was particularly preferable that X was 0.75 mm and Y was 0.08 mm.

Next, as shown in FIG. 3, the color photographic layer 1 color-printed on the substrate 3 has a color photographic portion 1 ′ and a white lattice portion 2 ′, and the color photographic layer 1 is transparent. Resin sheet 4 covers. In addition, since the color photographic layer 1 shown in FIG. 3 is assumed to be formed by offset printing, the white lattice portion 2 ′ has a hollow shape, and the color photographic portion 1 ′ is formed by dots. It is expressed in a shape.

As the substrate 3, various mouse pad substrates conventionally used can be used, and among them, the substrate 3 has flexibility, a high surface specific value, and excellent chargeability. In view of this, it is preferable to use a polyolefin sheet such as a polyvinyl chloride sheet or a polyvinylidene chloride sheet, or a polyester sheet such as a polyethylene terephthalate sheet. If the base material 3 is excellent in chargeability, the entire mouse pad can be easily adhered to the place of use such as a desk surface by electrostatic attraction, and the mouse pad is peeled off. This has the effect that dirt, such as adhesive and dust, is unlikely to remain on traces as in the past.

The white color of the substrate 3 is preferably white in order to form the white lattice portion 2 ′ by hollowing out the photographic portion. In particular, in order to obtain a thin mouse pad, the thickness of the base material 3 may be about 0.15 to 1.0 mm.

Next, an adhesive layer is provided on the color photographic layer 1 (not shown), and a transparent resin sheet 4 is adhered to the transparent resin sheet 4. The transparent resin sheet 4 is not particularly limited as long as it has transparency and flexibility. Among them, it is preferable to use a polyethylene terephthalate sheet. The thickness of the transparent resin sheet 4 may be in a range that does not hinder detection of reflected light by the optical mouse, and is preferably thinner than the base material 3. Further, the surface of the transparent resin sheet 4 may be subjected to surface processing such as embossing from the viewpoint of adjusting the coefficient of friction of the surface to facilitate sliding of the optical mouse.

Further, the mouse pad for an optical mouse according to the present invention is made of, for example, poly-4-methylpentene-1 on the side of the substrate 3 opposite to the transparent resin sheet 4 as in the prior art. A non-adhesive release layer may be provided, and release paper may be temporarily adhered. At this time, since the base material 3 itself has a charging property, the release paper can be temporarily bonded by the electrostatic force. When the release paper is peeled off, the mouse pad can be stuck and fixed on a desk for use because of the non-adhesive release layer. After use, it can be temporarily attached to a display of a personal computer, for example, and stored.

In particular, if the thickness of the mouse pad of the present invention is reduced, the surface of the release paper opposite to the base material side can be used, and the mouse pad of the present invention can also be used as a post card. Here, FIG. 4 is a schematic plan view showing an embodiment in which the mouse pad of the present invention is used for a post card. FIG. 4 shows a case where the release paper 5 is temporarily adhered to the mouse pad of the present invention. On the back side, although not shown, a non-adhesive release layer, a substrate, a color photographic layer, an adhesive The layers and the transparent resin sheet are sequentially laminated.

As shown in FIG. 4, if a postal code box 6, a stamp-attached portion 7 and a ruled line 8 are printed on the surface of the release paper 5, it can be used as a post card having a mouse pad function, for example. It can also be used as direct mail. In addition, if the ear 9 is provided on the release paper 5, the release paper 5 can be easily separated from the mouse pad. In addition, the mouse pad for an optical mouse of the present invention can be variously changed in design according to the related art.
