Description

[Technical Field]

[0001] The present invention relates to a mouse pad. [Background technology]

[0002] Conventionally, information processing devices such as personal computers generally include a mouse as an input device. In recent years, optical mice have become common, which are equipped with a light-emitting element and a light-receiving element to optically detect the direction and speed of mouse movement. A mouse can be efficiently operated by moving it on a mouse pad placed on a desk. Mouse pads are made of various materials and are formed into a plate-like body to allow efficient mouse movement.

[0003] Meanwhile, against the backdrop of the COVID-19 pandemic, the number of products with antibacterial and antiviral properties is increasing. One method for imparting antibacterial and antiviral properties to products is to apply a paint with antibacterial and antiviral properties to the surface of the product. For example, Patent Document 1 describes a mouse pad with an antibacterial layer and antibacterial properties. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3157464 Summary of the Invention [Problem to be solved by the invention]

[0005] Mouse pads are products that people touch on a daily basis, so it is very important that they have antibacterial and antiviral properties. However, because mouse pads are designed to be used by optical mice, even with normal use the antibacterial and antiviral coating on the surface will wear away, leading to a decline in their antibacterial and antiviral properties.

[0006] The present invention has been made in view of the above circumstances, and aims to suppress the decline in antibacterial and antiviral functions. [Means for solving the problem]

[0007] The mouse pad of the present invention is a mouse pad for an optical mouse, and comprises a sheet member having a plurality of protrusions on its upper surface, and a coating film formed on the upper surface that has at least one of antibacterial and antiviral functions, and the height of the plurality of protrusions is equal to or greater than the thickness of the coating film. [Effects of the Invention]

[0008] According to the present invention, a mouse pad can be provided that can suppress the deterioration of antibacterial and antiviral functions. [Brief explanation of the drawings]

[Figure 7] FIG. 2 is a plan view showing another example of the mouse pad 10. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] (Embodiment) <Mouse pad 10 according to one embodiment of the present invention> 1 is a plan view showing an example of a mouse pad 10 according to an embodiment of the present invention. Mouse pad 10 is a mouse pad for an optical mouse. The optical mouse may be, for example, a laser type, a blue LED (Light Emitting Diode) type, an IR (Infrared rays) LED type, or an optical (red LED) type mouse.

[0012] With respect to mouse pad 10, two directions that are parallel to the planar direction of mouse pad 10 and perpendicular to each other are defined as the X direction (horizontal direction in FIG. 1) and the Y direction (vertical direction in FIG. 1). The direction perpendicular to the planar direction of mouse pad 10 is defined as the Z direction (depth direction in FIG. 1). The positive direction of the Z direction (forward direction in FIG. 1) is defined as the upward direction, and the negative direction of the Z direction (depth direction in FIG. 1) is defined as the downward direction.

[0013] In this case, the mouse pad 10 is placed on a desk or the like with the downward surface of the mouse pad 10 serving as the bottom surface. The upward surface of the mouse pad 10 serves as the top surface, and an optical mouse is placed on the top surface.

[0014] Mouse pad 10 is a substantially rectangular plate-like body. The multiple protrusions 10a shown as dots in Fig. 1 are minute protrusions on the top surface of mouse pad 10. At least in an unused state, mouse pad 10 has multiple protrusions 10a on its top surface, as shown in Fig. 1.

[0015] <Cross-section of Mouse Pad 10> Figure 2 is a partial cross-sectional view of mouse pad 10. Figure 2 shows a portion of the cross section of mouse pad 10 cut in the thickness direction (Z direction). As shown in Figure 2, mouse pad 10 is composed of at least sheet member 11 and coating film 12.

[0016] The sheet member 11 is formed of a material such as PET (Polyethylene Terephthalate), for example. The upper surface of the sheet member 11 is provided with a plurality of protrusions 11a that protrude upward (in the positive Z direction). The upper surface of the sheet member 11 is the upward surface of the sheet member 11. In other words, the upper surface of the sheet member 11 is the surface on which the optical mouse is placed, i.e., the surface opposite the bottom surface of the mouse pad 10, and is the upper surface in FIG. 2.

[0017] The protrusions 11a are provided in a specific use area 11b on the upper surface of the sheet member 11, and the coating film 12 is also formed in this use area 11b. In the example of Figures 1 and 2, the entire upper surface of the sheet member 11 is the use area 11b.

[0018] The protrusions 11a have a shape in which the area of ​​the plane (plane parallel to the planar direction of the sheet member 11) perpendicular to the Z direction (the protruding direction of the protrusions 11a) decreases toward the top (tip). In the example of Fig. 2, the protrusions 11a have a hemispherical shape with the bottom surface facing downward and the spherical surface facing upward. The multiple protrusions 11a are provided on the top surface of the sheet member 11 in a staggered arrangement.

[0019] The protrusions 11a can be formed by, for example, molding, texturing, embossing, etc. Alternatively, the protrusions 11a may be formed by, for example, sprinkling a powder such as beads on a flat plate-like body that will become the sheet member 11 and then coating it from above. The method for forming the protrusions 11a is not limited to these, and various other methods can be used.

[0020] As shown in Fig. 2, the height of the multiple protrusions 11a is uniform. The height of the protrusions 11a is the distance in the Z direction (the protruding direction of the protrusions 11a) between the tip of the protrusions 11a and the position of a flat portion of the upper surface of the sheet member 11 where no protrusions 11a are present. The uniform height of the multiple protrusions 11a means that the height of the multiple protrusions 11a is uniform enough to allow, for example, an optical mouse to slide on the multiple protrusions 11a. h0 is the average height of the protrusions 11a.

[0021] The coating film 12 is formed on the upper surface of the sheet member 11. The coating film 12 is a functional coating film having at least one of antibacterial and antiviral functions. Titanium oxide can be used as an example of the material for the coating film 12, but the coating film 12 is not limited to this, and various functional coating films having at least one of antibacterial and antiviral functions can be used.

[0022] The coating film 12 is formed in a uniform manner over the entire upper surface of the sheet member 11. That is, the coating film 12 is formed not only on flat portions of the upper surface of the sheet member 11 where the protrusions 11a are not provided, but also on the portions of the protrusions 11a. As a result, the shape of the protrusions 11a of the sheet member 11 under the coating film 12 appears as the shape of the coating film 12, resulting in the protrusions 10a shown in FIG. 1.

[0023] As shown in Figure 2, the thickness of the coating film 12 is uniform. The thickness of the coating film 12 is, for example, the length of the coating film 12 in the Z direction. Alternatively, the thickness of the coating film 12 is, for example, the shortest distance between the upper and lower surfaces of the coating film 12. The coating film 12 being uniform in thickness means that, for example, the thickness of the coating film 12 is uniform enough that an optical mouse can slide over the protrusions 10a (see Figure 1) of the coating film 12 that reflect the shape of the protrusions 11a of the sheet member 11.

[0024] Specifically, the coating film 12 is formed by a uniform method over the entire plane, so that the average thickness of each region in the plane of the coating film 12 is uniform. For example, when the coating film 12 is formed by uniform spray coating over the entire plane, the thickness of each position on the coating film 12 will vary slightly in a dot pattern (for example, within a range of 0.05 μm to 0.5 μm), but the average thickness of each region obtained by dividing the coating film 12 in the plane (for example, each square region of 1 cm on each side) will be uniform.

[0025] t0 shown in FIG. 2 is the average thickness of the coating film 12. t0 is, for example, in the range of 0.05 μm or more and 30 μm or less, preferably in the range of 0.05 μm or more and 5 μm or less. By setting t0 to 0.05 μm or more, it is possible to easily form a coating film 12 with fewer defects. Furthermore, even if t0 is greater than 5 μm, it is difficult to improve the antibacterial and photoviral effects. Therefore, by setting t0 to 5 μm or less, it is possible to efficiently obtain the antibacterial and photoviral effects with a small amount of paint.

[0026] In the mouse pad 10, the bottom surface of the optical mouse only contacts the tips of the protrusions 10a, reducing the contact area between the mouse pad 10 and the optical mouse, allowing the optical mouse to slide smoothly. This improves the operability of the optical mouse. Furthermore, because wear caused by the sliding of the optical mouse is limited to the tips of the protrusions 10a, the remaining area of ​​the coating film 12 can be maintained for a long period of time, preventing a decline in the antibacterial and antiviral functions of the mouse pad 10.

[0027] Furthermore, the average height h0 of protrusions 11a is equal to or greater than the average thickness t0 of coating film 12. As a result, even if coating film 12 formed on protrusions 11a is scraped off due to wear caused by the sliding of the optical mouse, coating film 12 formed on the portions of the upper surface of sheet member 11 where protrusions 11a are not provided remains intact, thereby further preventing a decrease in the antibacterial and antiviral functions of mouse pad 10.

[0028] Furthermore, the area of ​​the surface perpendicular to the protrusion direction of the protrusion 11a decreases as it approaches the tip, thereby reducing the contact area with the optical mouse at the beginning of use and allowing the optical mouse to slide smoothly, while ensuring strength compared to a configuration in which the protrusion 11a is shaped like a thin cylinder, for example, and preventing situations such as the protrusion 11a breaking.

[0029] Furthermore, since the protrusions 11a are arranged in a staggered pattern on the upper surface of the sheet member 11, the optical mouse is less likely to get caught even though the area occupied by the protrusions 11a is small, thereby reducing the contact area with the optical mouse and reducing friction, allowing the optical mouse to slide smoothly.

[0030] <The wear process of mouse pad 10> 3 and 4 are diagrams showing an example of the wear process of mouse pad 10. Over the period of use of mouse pad 10, the coating film 12 wears away from the tip of the portion (protrusion 10a) formed on protrusion 11a, mainly due to friction with the bottom surface of the optical mouse.

[0031] Figure 3 shows a state in which the tips of protrusions 11a are exposed on the surface of mouse pad 10 due to wear of coating 12. In this case, the centers of protrusions 10a of mouse pad 10 shown in Figure 1 become protrusions 11a. In the state shown in Figure 3, protrusions 11a wear out along with coating 12 as mouse pad 10 is used. However, because protrusions 11a are less susceptible to wear than coating 12, the rate at which the surface of mouse pad 10 wears in the Z direction is lower.

[0032] Therefore, coating film 12 formed on the portion of the upper surface of sheet member 11 where protrusions 11a are not provided can be maintained lower than protrusions 11a for a long period of time, which extends the remaining life of coating film 12 formed on the portion of the upper surface of sheet member 11 where protrusions 11a are not provided, and prevents a decrease in the antibacterial and antiviral functions of mouse pad 10.

[0033] Furthermore, as protrusions 11a wear, the area of ​​contact with mouse pad 10 increases, and the wear rate of the surface of mouse pad 10 in the Z direction gradually decreases. This allows coating film 12 formed on the upper surface of sheet member 11 in the areas where protrusions 11a are not provided to remain for a longer period of time, thereby preventing a decrease in the antibacterial and antiviral functions of mouse pad 10.

[0034] 4 shows a state in which the height of coating 12 formed on the flat portion of sheet member 11 becomes the same as the height of protrusions 11a due to wear of coating 12 and protrusions 11a, resulting in a flat surface of mouse pad 10. In this state, coating 12 formed on the flat portion of sheet member 11 also begins to wear away, but because protrusions 11a remain, the rate of wear of the surface of mouse pad 10 in the Z direction slows down.

[0035] Therefore, the remaining period of coating film 12 formed on the portion of the upper surface of sheet member 11 where protrusions 11a are not provided can be extended, and deterioration of the antibacterial and antiviral functions of mouse pad 10 can be suppressed.

[0036] <Dimensions of sheet member 11> Fig. 5 is a diagram illustrating an example of the dimensions of the sheet member 11. In Fig. 5, a plan view 51 shows the protrusion 11a of the sheet member 11 as viewed from above, and a cross-sectional view 52 shows a portion of a cross section of the sheet member 11 cut in the thickness direction (direction perpendicular to the planar direction). Φ is the diameter of the protrusion 11a in the planar direction of the sheet member 11.

[0037] As shown in plan view 51, the multiple protrusions 11a are arranged in a staggered arrangement, shifted alternately vertically and horizontally in the planar direction of the sheet member 11. The staggered arrangement can be considered, for example, as an arrangement of a first group of positions aligned (aligned vertically and horizontally) at intervals W in the X direction and at intervals D in the Y direction in the planar direction of the sheet member 11, and a second group of positions shifted from the first group of positions by W / 2 in the X direction and D / 2 in the Y direction (i.e., diagonally). In this case, the interval (pitch) in the X direction between the staggered protrusions 11a is W, and the interval (pitch) in the Y direction between the staggered protrusions 11a is D. In the example of FIG. 5, W=D.

[0038] For example, W=D=0.92 [mm] and Φ=0.3 [mm]. In this case, the area of ​​one protrusion 11a in the planar direction of the sheet member 11 is 0.07065 [mm]. 2 The rectangular region 51a shown in the plan view 51 can be considered to include one protrusion 11a and four quarters of the protrusion 11a, that is, two protrusions 11a. The area of ​​the rectangular region 51a is W×D=0.8464 [mm 2 ].

[0039] Therefore, the ratio of the area occupied by the protrusion 11a to the area of ​​the rectangular region 51a is 0.07065 mm 2 ]×2 / 0.8464[mm 2 ]≒16.7%. Since usable area 11b of sheet member 11 can be considered as rectangular areas 51a arranged adjacently vertically and horizontally, the area ratio of usable area 11b occupied by multiple protrusions 11a is also approximately 16.7%. In this case, the area ratio of the portion of usable area 11b where protrusions 11a are not provided is approximately 83.3%.

[0040] As a result, even if the entire portion of the coating film 12 above the protrusion 11a is scraped off, the remaining area of ​​the coating film 12 will be 83.3% or more of its original area, and sufficient antibacterial and antiviral functions can be maintained.

[0041] For example, it is preferable that the area occupied by the protrusions 11a in the usable area 11b is less than 20%. As a result, even if the entire portion of the coating film 12 above the protrusions 11a is scraped off, the remaining area of ​​the coating film 12 will be more than 80% of the original area, and sufficient antibacterial and antiviral functions can be maintained.

[0042] Furthermore, by shaping protrusion 11a so that the area of ​​the surface perpendicular to the protrusion direction decreases toward the tip, even if part of protrusion 11a is exposed on the surface of mouse pad 10, coating film 12 remains on the remaining part of protrusion 11a. This increases the remaining area of ​​coating film 12, allowing sufficient antibacterial and antiviral functions to be maintained for a longer period of time.

[0043] <Average spacing between multiple protrusions 11a> The average spacing between the multiple protrusions 11a is preferably, for example, 3 mm or less. This prevents the typical sole of an optical mouse from getting caught between the protrusions 11a and interfering with the sliding of the optical mouse. The sole of an optical mouse is, for example, a circular or oval plate provided at a position on the bottom surface of the optical mouse to adjust the ease of sliding of the optical mouse.

[0044] The average spacing between the multiple protrusions 11a is, for example, the average of the above-mentioned W and D. Alternatively, the average spacing between the protrusions 11a may be the average of the shortest spacing between the protrusions 11a. The shortest spacing between a certain protrusion 11a is the spacing between that protrusion 11a and the protrusion 11a closest to that protrusion 11a.

[0045] <Average height of multiple protrusions> The average height h0 of the multiple protrusions 11a is preferably 0.7 mm or less, for example. This allows for sufficient optical reading accuracy in a typical optical mouse. For example, if the average height h0 exceeds 0.7 mm, the focus of the light receiving element of the optical mouse becomes misaligned, making it difficult to perform optical reading with sufficient accuracy.

[0046] <Remaining area of ​​coating film 12 according to wear of protrusion 11a> 6 is a diagram illustrating an example of the remaining area of ​​the coating film 12 depending on the wear of the protrusions 11a. For example, the average height h0 of the protrusions 11a is set to 0.15 mm, which is the same as the radius of the protrusions 11a. The shape of the protrusions 11a is set to a hemispherical shape with the bottom surface facing downward and the spherical surface facing upward, similar to the example in FIG. 2 etc.

[0047] The height h1 is 90% of the initial height h0 of the protrusion 11a. When the protrusion 11a is worn down to the height h1 (when it is worn down by 10%), the diameter φ1 of the circular upper surface of the protrusion 11a is 0.13 mm, and the area of ​​the circular upper surface of the protrusion 11a is 0.013 mm. 2 ], and the remaining area of ​​the coating film 12 is 96.8% of the original area.

[0048] The height h2 is 75% of the initial height h0 of the protrusion 11a. When the protrusion 11a is worn down to the height h2 (when it is worn down by 25%), the diameter φ2 of the circular upper surface of the protrusion 11a is 0.20 mm, and the area of ​​the circular upper surface of the protrusion 11a is 0.031 mm. 2 ], and the remaining area of ​​the coating film 12 is 92.7% of the original area.

[0049] The height h3 is 50% of the initial height h0 of the protrusion 11a. When the protrusion 11a is worn down to the height h3 (50% worn), the diameter φ3 of the circular upper surface of the protrusion 11a is 0.26 [mm], and the area of ​​the circular upper surface of the protrusion 11a is 0.053 [mm]. 2 ], and the remaining area of ​​the coating film 12 is 87.5% of the original area.

[0050] The height h4 is 25% of the initial height h0 of the protrusion 11a. When the protrusion 11a is worn down to the height h3 (when it is worn down by 75%), the diameter φ4 of the circular upper surface of the protrusion 11a is 0.29 mm, and the area of ​​the circular upper surface of the protrusion 11a is 0.066 mm. 2], and the remaining area of ​​the coating film 12 is 84.3% of the original area.

[0051] In this way, by shaping the protrusion 11a so that the area of ​​the surface perpendicular to the protrusion direction becomes smaller as it approaches the tip, even if part of the protrusion 11a becomes exposed on the surface of the mouse pad 10, the reduction in the remaining area of ​​the coating film 12 is slowed, and sufficient antibacterial and antiviral functions can be maintained for a longer period of time.

[0052] <Another example of Mouse Pad 10> FIG. 7 is a plan view showing another example of mouse pad 10. In the example shown in FIG. 1 and elsewhere, the entire upper surface of sheet member 11 is described as usable area 11b, but a configuration in which only a portion of the upper surface of sheet member 11 is usable area 11b may also be used. For example, sheet member 11 may be configured with frame portion 10b inscribed on the outer periphery of sheet member 11 and usable area 11b surrounded by frame portion 10b. In this case, as shown in FIG. 7, frame portion 10b, which is not provided with protrusions 11a or coating film 12, is exposed on the surface of mouse pad 10.

[0053] In such a case, it is also preferable that the area occupied by the plurality of protrusions 11a in the usable area 11b is less than 20%. As a result, even if the entire portion of the coating film 12 above the protrusions 11a in the usable area 11b is scraped off, the remaining area of ​​the coating film 12 will be more than 80% of the original area, and sufficient antibacterial and antiviral functions can be maintained.

[0054] <Use of the multiple protrusions 11a as indicators> For example, the sheet member 11 (protrusions 11a) and the coating film 12 may be different colors. In this case, in the initial state where the protrusions 11a are not exposed, as shown in Figures 1 and 2, only the color of the coating film 12 is visible on the surface of the mouse pad 10. Then, as the surface of the mouse pad 10 wears and the tips of the protrusions 11a become exposed as shown in Figure 3, the color of the sheet member 11 appears in dots on the surface of the mouse pad 10. As the surface of the mouse pad 10 wears further and the exposed area of ​​the protrusions 11a increases as shown in Figure 4, the area of ​​the color of the sheet member 11 that appears on the surface of the mouse pad 10 increases. This allows the user to know the degree of deterioration of the antibacterial and antiviral functions based on the size of the colored area of ​​the sheet member 11 that appears on the surface of the mouse pad 10.

[0055] Furthermore, when the surface of mouse pad 10 wears further and protrusions 11a in a certain area of ​​mouse pad 10 (for example, the center) are worn down to the bottom, all of coating film 12 in that area is also worn down, and only the color of sheet member 11 is visible on the surface of mouse pad 10. This allows the user to know that the antibacterial and antiviral functions of that area have been lost.

[0056] In this way, by making the sheet member 11 (protrusions 11a) and the coating film 12 different colors, the multiple protrusions 11a can also be used as indicators to inform the user of the remaining status of the antibacterial and antiviral functions of the coating film 12.

[0057] <Dimensional variations> The dimensions of sheet member 11 described in Figure 5 and elsewhere are merely examples, and various modifications are possible. For example, the average spacing between protrusions 11a and the diameter Φ of protrusions 11a may be changed within a range in which the proportion of the area occupied by protrusions 11a in use region 11b is less than 20%. In other words, by reducing the diameter Φ of protrusions 11a, the proportion of the area occupied by protrusions 11a in use region 11b can be kept less than 20% even if the average spacing between protrusions 11a is increased.

[0058] <Modifications of the Planar Shape of Mouse Pad 10 and Usable Area 11b> Although the planar shapes of mouse pad 10 and usable area 11b have been described as being approximately rectangular, the planar shapes of mouse pad 10 and usable area 11b are not limited to this and can be various shapes such as circular or more complex shapes.

[0059] <Modifications of the shape of the protrusion 11a> Although the protrusions 11a have been described as being hemispherical in shape, the present invention is not limited to this configuration. For example, the protrusions 11a may be in an elliptical hemispherical shape, a pyramidal shape, or any other shape.

[0060] Although the protrusion 11a has been described as having a shape in which the area of ​​the surface perpendicular to the protruding direction decreases toward the tip, the shape is not limited to this. For example, the protrusion 11a may have a cylindrical shape, a prismatic shape, or any other shape.

[0061] Furthermore, the protrusions 11a are not limited to having a geometrically regular shape, and may have a distorted shape.

[0062] <Modifications of the arrangement of the plurality of protrusions 11a> Although the configuration in which a plurality of protrusions 11a are provided in a staggered arrangement on the upper surface of the sheet member 11 has been described, the configuration is not limited to this. For example, a configuration in which a plurality of protrusions 11a are provided on the upper surface of the sheet member 11 in an aligned arrangement or a random arrangement may also be used.

[0063] As described above, the present specification discloses the following:
