Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mouse pad that can be used on both sides in the same manner.

[0002]

[Prior art]

 As is well known, a mouse of a personal computer is operated by sliding the mouse pad on a desktop. As the surface characteristics of these mouse pads, it is necessary to have an appropriate sliding characteristic with the ball of the mouse device. That is, if the surface of the mouse pad is too slippery, the ball of the mouse device slides without rotating, and the hand operation and the movement of the cursor on the display device cannot be adapted. On the other hand, if the surface of the mouse pad is not sufficiently slippery, the slip resistance of the main body of the mouse device increases, making it difficult to perform operations and easily causing fatigue of the hands. On the other hand, as for the back surface characteristics, it is necessary to be sufficiently fixed to tables and the like of various materials. That is, if the fixation of the mouse pad to the table or the like is not sufficient, the mouse device slides with the running of the mouse device, and the operation of the hand and the movement of the cursor of the display device cannot be adapted.

[0003] As a mouse pad having a general configuration, a mouse pad having a configuration in which a foam sheet is used as a base sheet, a surface sheet is laminated on the base sheet, and a sliding layer is formed on the surface sheet is widely used. Are known. As the sliding layer, an adhesive layer made of a woven or knitted material, a resin uneven layer containing fine beads, and a laminate layer made of an expanded porous polytetrafluoroethylene sheet were used. In recent years, mousepads printed with various anime characters and designs have also been sold in response to the increase in the number of young PC users.

[0004]

[Problems to be solved by the invention]

 However, since the conventional mouse pad is printed only on the front side, if the user of the personal computer is not only one person, but also a parent and child, sibling, sibling, sister, sibling, the mouse is used. When purchasing a pad, one of them had to entrust the choice, otherwise fights began with brothers and others. Also, even if you purchase a mouse pad with your favorite print, if you always see the print, especially younger children will get tired easily and want a different print mouse pad. There was also.

[0005]

[Means for Solving the Problems]

 The present invention has been found after intensive studies in view of the above, and is characterized in that a large number of fine protrusions are formed on the front and back surfaces of a transparent soft plastic sheet monolayer or laminate. A mouse pad in which transparent plastic sheets having transparency are laminated on both sides of a core sheet subjected to double-sided printing, and a large number of fine protrusions are formed on the outer surface side of each soft plastic sheet. Is proposed.

[0006]

[Action]

 The mouse pad of the present invention having the above configuration can be used in the same manner on the front and back surfaces. A mouse pad, which is a single layer or a laminate of a soft plastic sheet, has transparency as a product, so that the back side can be viewed from the front side. In addition, a mouse pad that has a double-sided printed core sheet interposed between soft plastic sheet laminates makes it possible to see designs and the like printed from both sides, especially for children, etc. The product has twice the commercial value compared to the conventional product with only one-sided printing, and it is timeless.

[0007]

[Embodiment of the invention]

 The soft plastic sheet having transparency in the present invention is made of a thermoplastic resin, and if a large number of fine projections are formed by pressing a stamping mold described below at an appropriate temperature, The type and thickness, the presence or absence of a friction adjusting layer and a printing layer, and the presence or absence of a laminating adhesive layer (in the case of a laminate) are not limited. Further, as long as it has transparency (transparency), a translucent sheet or a colored sheet may be used. The printing layer is generally provided on the inner surface side, but may be provided on the outer surface side where fine projections are formed thereafter. In this case, the printing layer and the friction adjusting layer that do not cause cracks or the like in the subsequent convex portion forming process are used.

The core sheet used in the present invention is not particularly limited as long as it does not cause at least deformation or expansion and contraction due to heating during the press-contact of the embossing plate described below. Can be used. For example, various paper base materials such as cardboard, synthetic paper, various resin sheets such as foamed elastic sheets, and printing on both sides thereof are not particularly limited in terms of the method or the like.

The shape of the fine convex portion is not particularly limited, but when the punching metal plate or the like is used as the embossing plate, it becomes substantially hemispherical. In order to obtain a desired convex shape, a concave portion corresponding to the shape may be engraved on the embossing plate. Although not particularly limited, the fine projections have a pitch of 0.4 to 3.0 φ, are arranged in a staggered or parallel arrangement with a pitch of 0.8 to 4.0, and are 1010 to 46 per unit area. The number is preferably 6 pieces / square inch, more preferably 0.5 to 1. It is preferable to provide 625 to 330 pieces / square inch per unit area in a staggered or parallel arrangement with a pitch of 1.09 to 1.50. Outside of these ranges, either mouse operability or desk slipperiness will be impaired.

The embossing plate may be a flat plate or a roll, and may be a plate having a large number of holes, such as a punched metal plate, or a plate having a large number of recesses. The setting conditions such as the diameter, pitch, density, etc. in the description of the fine projections may be regarded as the conditions for forming holes or recesses in the embossing plate.

In order to manufacture the mouse pad of the present invention, in the case of a single-layered body, the embossing plate is faced to the front and back surfaces of a transparent soft plastic sheet, and the projections are formed. In the case of a laminated body, a plurality of soft plastic sheets may be laminated, and the laminating process and the convex portion forming process may be performed simultaneously with the embossing plate facing the outer surface side of each soft plastic sheet. The conditions such as the heating temperature may be appropriately set depending on the material of the soft plastic sheet and the adhesive for lamination to be used. The same applies to the case where a core sheet is interposed. In this case, three-layer lamination is performed, but the lamination may be performed under appropriate conditions. In the case of a laminate without a core sheet, a laminating adhesive is often applied only to the inner surface of one soft plastic sheet. Although an adhesive for lamination is often applied to the inner surface, it is not particularly limited to these.

The mouse pad of the present invention has an unprecedented characteristic that the front and back surfaces can be used in the same manner, but is further roughly classified into a type in which the core sheet is not interposed and a type in which the core sheet is interposed. In addition, each of them has characteristics and effects which have not existed before.

[0013] The mouse pad without the intermediate sheet is composed of a single layer or a laminate of a transparent soft plastic sheet, so that the entire product retains transparency. Therefore, the desk surface can be visually recognized through the mouse pad. For example, if there are many data sheets on a desk, the mouse pad may hide the sheet, or the user may remove the mouse pad and search for the back side. In addition, inadvertently operating the mouse at that time may cause a malfunction. The characteristics described above do not require the removal of the mouse pad in such a case and do not cause malfunction. Or if you are a young child, you can place your favorite magazines and illustrations under the mouse pad and see them through the mouse pad. Further, since the mouse pad retains the material of the soft plastic sheet as it is, the mouse pad is extremely thin and has high flexibility, and can be formed into a mouse pad that can be rolled up and housed, for example. Further, when producing a mouse pad of this type, a single-layered body is printed on one side, and a laminated body is printed on the inner surface of one soft plastic sheet partially or completely. good. Since the printing in this case can be visually recognized from both the front and back sides, the visual effect of the double-sided printing type described later is also provided. In addition, the lamination of two soft plastic sheets in a laminate is generally performed by laminating the entire surface, but dare to laminate only two or three sides to form a sheet file that can accommodate various sheets inside. good. For example, a data sheet or the like may be sandwiched inside, or a child or the like may sandwich his or her favorite illustration. In particular, if an "underlay" is inserted, not only the "underlay" pattern and the like can be visually recognized, but also smoothness can be secured on a tatami mat or the like. Further, elasticity can be imparted to the mouse pad with an elastic sheet having cushioning properties interposed therebetween.

The mouse pad having the core sheet interposed therebetween has a structure in which the core sheet printed on both sides is interposed between the transparent soft plastic sheet laminates. Designs printed on both sides of the core sheet can be visually recognized, and it has twice the commercial value, especially for children, etc., compared to the conventional single-sided mouse pad, and a mouse pad that does not get tired. Become. Various properties can be imparted by selecting the material of the core sheet. For example, if a very flexible material is used as the core sheet, as in the case of two soft plastic sheets, the flexibility of the entire product will be maintained, and the flexibility of the product will be improved by using a core sheet with appropriate hardness. Sex can also be adjusted. Elasticity can also be imparted by using an elastic sheet as the core sheet. Further, as the core sheet, a sheet having transparency and having both sides printed may be used. In this case, different designs can be visually recognized from both sides, and transparency is maintained as a whole, so that the above-mentioned transparent type visual effect is also achieved.

Further, a UV paint 7 for appropriately controlling mouse operability and disk slippage is applied to one side of the soft polyolefin film (sheet) 2 and dried, and an adhesive 3 for lamination is applied to the other side and dried. Two pieces were prepared. Then, as shown in FIG. 3 (a), the core sheet 6 is laminated between the soft polyolefin sheets 2 and 2 with the adhesive applied surface inside, and the punched metal plate 1 is placed on the UV coated surface outside. , 1 are put on the upper and lower sides, put in a flat pressure multi-stage press machine, and laminated while heating under predetermined press conditions as shown in FIG. The projections 4 were formed and cooled. This was cut into a predetermined size with rounded corners to obtain a mouse pad 8 shown in FIG. The mouse pad 8 thus obtained can be used in the same way on the front and back, and by having two different patterns, the child's tiredness is always changed from the same pattern as in the conventional one. Therefore, it can be said that it is highly commercial. In addition, it has good fixation to a disk or the like, and the running property of the mouse and the movement of the cursor of the display device are well adapted. Although this embodiment is an example of a completely transparent product, it is needless to say that printing may be performed on the inner surface of the soft polyolefin sheet opposed to the soft polyolefin sheet. Considering the use of the front and back by selecting a picture design, it is an innovative mouse pad that is transparent and refreshing.

Although the present invention has been described based on the embodiments, the present invention is not limited to the above embodiments, and can be implemented in any manner unless the configuration described in the claims for utility model registration is changed. be able to.

[0022]

[Effect of the invention]

 As described above, the mouse pad of the present invention has a configuration in which many fine projections are formed on both the front and back surfaces, and the front and back surfaces can be used in the same manner.

In particular, a mouse pad composed of a single layer or a laminate of a soft plastic sheet has transparency as a product, so that the back side can be viewed from the front side. The mouse pad can be made extremely lightweight and highly flexible, or printed on one side in the case of a single-layer body, or printed on the inner surface of one soft plastic sheet in the case of a laminate. It can also be an interesting product. Further, in the case of a laminate, only two sides or three sides may be laminated to form a sheet file capable of storing various sheets inside. In this case, for example, a data sheet, an illustration, an “underlay”, an elastic sheet, or the like may be housed therein, and a visual effect, smoothness, elasticity, or the like may be appropriately provided.

In addition, a mouse pad having a configuration in which a core sheet subjected to double-sided printing is interposed between soft plastic sheet laminates allows a design or the like printed from both sides to be visually recognized, and particularly a child or the like. For consumers, it will be timeless with twice the commercial value of conventional products that only use single-sided printing.
