Therefore, the track ball 3 can smoothly and securely rotate as the mouse 2 is moved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used for moving a cursor on a display screen of a computer display device.
For example, it relates to a pad for a position input device for mounting a mouse and rolling a trackball of the mouse.

[0002]

2. Description of the Related Art Generally, various position input devices are used to move a cursor displayed on a display screen of a computer display device. For example, a mouse is widely used as a handheld position input device. Has been done.

In this case, when operating the mouse, a flat pad is usually used, and the trackball forming the mouse is displayed on the display screen of the computer by rolling on the pad. The cursor is configured to move in a desired direction.

[0004]

By the way, as this type of pad, a rubber pad 1 is usually used as shown in FIG. 3, and a mouse 2 is formed on the upper surface 1a of the rubber pad 1. The track ball 3 is brought into contact with the mouse 2, the mouse 2 is moved in the arrow direction, and the track ball 3 is rotated in the arrow direction to roll. Since the rubber pad 1 is usually left standing on a desk or a table, dust accumulates on the upper surface 1a of the rubber band 1 and the dust sticks to the dusty area due to moisture. May occur. When this phenomenon occurs, in some cases, the surface of the trackball 3 may be turned over and stuck. When these phenomena occur, smooth rolling of the track ball 3 which is originally required to be accurately rolled is impeded, or slipping is likely to occur, resulting in poor operability. May occur. In addition, even if it is not the case, the track ball may turn around. Although some cloths are adhered to the surface to prevent them from turning around, when the cloths are adhered, the weaving yarn may interfere with the smooth rotation of the trackball.

The present invention solves this kind of inconvenience by always maintaining the cleanliness of the pad and, at the same time, maintaining the cleanliness of the surface of the trackball of a handheld position input device such as a mouse. Provided is a pad for a position input device capable of easily and highly accurately operating the trackball constituting the pad and preventing the pad or mouse trackball from slipping due to dust or the like as much as possible. The purpose is to do.

[0006]

In order to achieve the above-mentioned object, the present invention provides a hand-held position input device, usually called a mouse, used for moving a cursor on a display screen of a computer display device. A pad for a position input device for rolling a trackball, in which a flocked transfer receiving layer as a core material is formed on the surface of a rubber thick plate formed like a porous and elastic sponge, and flocked transfer is performed. The flocked layer is formed by densely implanting short fibers on the receiving layer using a flocked transfer machine.

[0007]

In the position input device pad according to the present invention, the porous and elastic sponge is placed with the back side of the rubber thick plate formed like a porous and elastic sponge placed on a table or the like. A trackball of a hand-held position input device is placed in a rolling state on a flocked layer provided on the surface side of a rubber thick plate formed in a shape. Then, by moving the handheld position input device in a desired direction, the cursor is moved on the display screen of the display device. At this time, if the handheld position input device is a mouse, the trackball that constitutes the mouse rolls on the densely planted short fibers that constitute the flocked layer. Therefore, a large frictional force is not generated between the trackball and the flocked layer, and it is possible to prevent dust and the like from intervening between the trackball and the flocked layer. As a result, it becomes possible to smoothly and easily move the handheld position input device such as a mouse, and it is possible to effectively avoid slipping and perform highly accurate position input work.

Further, since the flocked transfer receiving layer having a core material function is interposed between the thick rubber plate formed into a porous and elastic sponge and the flocked layer, the pad itself has an appropriate hardness. Can have.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A pad for a position input device according to the present invention will be described below with reference to the accompanying drawings.

1 and 2, reference numeral 10
Shows a pad for a position input device according to the present invention, and this pad 10 places and moves a mouse 2 which is a handheld position input device in order to move a cursor on a display screen of a display device of a personal computer (not shown). . The pad 10 has a back surface 12a side, which is placed on a table or the like, and a rubber thick plate 1 formed in the shape of a porous and elastic sponge.
2 and a flocked layer 14 on which the trackball of the mouse 2 rolls by being fixed to the other surface 12b side of the rubber thick plate 12 formed in the shape of a porous and elastic sponge. A flocked transfer receiving layer 16 which is a core material is interposed between the rubber thick plate 12 formed in a sponge shape and the flocked layer 14.

The rubber thick plate 12 formed in the shape of a porous and elastic sponge is made of, for example, sponge rubber, and the other surface of the rubber thick plate 12 formed in the shape of a porous and elastic sponge. A flocked layer 14 in which short fibers are densely planted is formed on 12b via a core material 16. The core material 16 is a rubber thick plate 12 formed in a porous and elastic sponge shape.
Is fixed to the surface 12b by welding. This core material 1
6 has a cross-linking agent 20 for fixing and holding the flocked layer 14 and bridging the thermoplastic synthetic resin 18, and the pad 10
After being applied to the entire surface of the pad to a desired thickness and then dried, the surface of the pad 10 can be provided with elasticity and a desired hardness. The core material 16 of the present invention is capable of transferring flocking because it is impossible to directly perform flocking operation on a rubber thick plate formed into a porous and elastic sponge. In order to adjust the elasticity of the core material, a cloth may be stretched on the coated surface of the synthetic resin.

The flocked layer 14 has short fibers 22 densely planted therein. The short fibers 22 are made of nylon, rayon,
It is made of a material such as polyester or cotton and has a length of approximately 1 mm. The flocked layer 14 can also be formed by densely fixing and fixing short fibers of one color, but it is possible to form a multicolor pattern by using the short fibers 22 each colored in a desired color. The flocked layer 14 can be produced by using a flocked transfer machine produced by applying the silk screen printing method disclosed in Japanese Patent Publication No. 25667/1990. Further, the pad 10 can be obtained based on the multicolor block transfer body and the manufacturing method thereof disclosed in JP-A-64-61299.

Next, the function of the pad 10 thus constructed will be described. As shown in FIG. 2, when the mouse 2 is placed on the flocked layer 14 and moved in a predetermined direction as shown by an arrow, the trackball 3 constituting the mouse 2 rotates in the direction of the arrow to be illustrated. The cursor moves on the display screen of the computer display device.

In this case, in this embodiment, since the trackball 3 is placed on the densely packed short fibers 22 constituting the flocked layer 14, as shown in FIG. 2, the densely packed short fibers located below the trackball 3 are arranged. 22 is in a bent state and is in point contact with the outer peripheral surface of the trackball 3. Therefore, the trackball 3 can smoothly and reliably rotate as the mouse 2 moves. Moreover, since the densely packed short fibers 22 are in point contact with the outer peripheral surface of the trackball 3 without making surface contact, no frictional force is generated between the densely packed short fibers 22 and the trackball 3. . Therefore, the mouse 2 can be easily and accurately moved in a desired direction, and in particular, an effect that the cursor can be efficiently moved in a minute range can be obtained.

Further, by using the densely packed short fibers 22, no friction or the like is attached to the trackball 3,
Further, even if dust adheres, it has a function of removing it. In addition, abrasion dust and the like are not generated along with the movement of the trackball 3, and it is possible to avoid defective movement of the cursor due to slippage of the trackball 3 and interruption of operation due to removal of dust from the trackball 3. be able to.

The pad 10 is made of a sponge-like rubber 12 having a porous and elastic property, and has a core material 16 as a layer made of a stretched thermoplastic synthetic resin on the surface of which intervenes a core material such as nylon. Since it is composed of the flocked layer 14 formed by densely planting short fibers, it has an advantage that it is suitable for washing with water as a whole and that it is easy to maintain cleanliness at any time. In addition, the short-hair fibers 22 pre-colored in a desired color are used in a multi-colored manner without printing a design or the like on the surface of the flocked layer 14 by the flocked transfer machine to which the invention described in Japanese Patent Publication No. 25667/1990 is applied. The design is easily constructed. still,
The core material 16 may be formed by impregnating a woven fabric, a non-woven fabric, or a knitted fabric with a thermoplastic synthetic resin mixed with a cross-linking agent, and adhering it to a rubber thick plate formed into a porous or elastic sponge. it can.

The position input device pad according to the present invention comprises:
The following effects can be obtained. Since the rolling of the trackball of the handheld position input device is performed by the flocked part in which the short fibers are planted, the frictional force between the trackball of the handheld position input device and the pad for the position input device can be reduced. Therefore, the handheld position input device can be moved smoothly. Further, it is possible to prevent dust and the like from adhering to the trackball of the handheld position input device as the trackball rolls. Furthermore, since the core material is interposed between the electrically insulating portion and the flocked portion, it is possible to secure a desired hardness of the pad as a whole and to smoothly roll the trackball of the handheld position input device. It is possible. At this time, the core material is a synthetic resin adhesive that holds the flocked portion, and there is no need to provide a dedicated core material, which is economical. Further, since the electrically insulating portion is a sponge-like synthetic resin body, the pad as a whole is suitable for washing with water and also suitable for repeated use.
