[0003]

[0002]

[0004]

2. Description of the Related Art Conventionally, mouse pads of this type shown in FIGS. 4 to 7 have been known.

FIG. 4 is a main sectional view of a conventional mouse pad, showing a state in which a mouse is placed on the mouse pad.

In the figure, reference numeral 1 denotes a mouse pad, which is made of soft synthetic rubber or soft urethane resin molded in a foamed or non-foamed manner and has a predetermined area and thickness. In addition, fine irregularities are formed on the surface of the mouse pad 1. The mouse pad 1 is placed on the upper surface of the desk 2, and the mouse 3 is placed on the mouse pad 1. The mouse 3 is molded of synthetic resin or the like, has a plurality of mouse legs 4, and a slide portion 5 made of synthetic resin is fixed to the bottom of each mouse leg 4. Further, a circular hole is provided in the substantially central bottom portion of the mouse 3, and a ball 6 made of hard rubber or urethane resin and having its surface formed with fine irregularities is loosely fitted therein.

When the mouse 3 is placed on the mouse pad 1, the slide portion 5 and the ball 6 come into contact with the mouse pad 1 by their own weight. Further, the ball 6 is in contact with a plurality of rollers 7 biased by a constant stress inside the mouse. Therefore, at the portion where the mouse pad 1 is in contact with the ball 6, the ball 6 is in contact with the mouse pad 1 with a constant surface area as shown in FIG. 5, which is an enlarged view of the portion X in FIG.

[0008]

In FIG. 4, the upper surface of the mouse 3 is covered with a palm (not shown), and the weight of the hand is applied from above the mouse to the mouse legs 4 to load the mouse legs 4 substantially evenly. When the sliding portion 5 of the mouse 3 is slid in the direction of arrow A while manually adjusting so that the ball is almost constant, the ball 6 rolls on the mouse pad 1 as shown by the arrow B, and accordingly. The roller 7 contacting the ball 6 is reversed as indicated by arrow C. The rotation of the roller 7 is detected and converted into an electric signal, and the obtained electric signal is input from the code 8 to a display device (not shown) to move the cursor on the display screen of the display device in a predetermined direction by a predetermined distance. ing.

[0009]

The conventional mouse pad, which is constructed as described above, has been used in many cases together with the ball type mouse because it is relatively inexpensive and easy to manufacture and process.

[0010]

However, since the conventional mouse pad is soft, even if the mouse is moved a minute distance in the direction of arrow D as shown in FIG.
Is deformed and moves together with the ball 6, the ball 6 cannot roll on the surface of the mouse pad 1, and it is difficult to delicately move the cursor on the display screen of the display device.

Further, since the mouse pad is soft, when the weight of the hand is applied to the mouse, the unevenness of the mouse pad surface in contact with each slide portion is crushed, and the contact area with each slide portion increases, so that the mouse pad increases. There is a drawback in that the frictional resistance during movement suddenly increases and the mouse cannot move smoothly on the mouse pad.

[0012]

Further, as shown in FIG. 7, since the mouse pad 1 is soft, each mouse leg portion 4 always sinks into the mouse pad 1 in an amount corresponding to the weight of the load of the hand 9, so that the mouse pad portion 1 is evenly stabilized on each slide portion 5. It is difficult to apply the load.
Further, since the mouse pad 1 is soft, each mouse leg 4 always sinks into the mouse pad 1 in an amount corresponding to the load weight of the hand 9, so that even if the mouse is stationary on the mouse pad, The shaft freely rotates as shown by arrows E and F. As a result, a play can be made between the movement of the mouse 3 and the ball 6, and the tracking of the ball 6 with respect to the movement of the mouse 3 becomes unstable.
In addition, the grease on the surface of the mouse pad adheres to the surface of the mouse pad during use, and the ball slips on the mouse pad, making it impossible to accurately move the cursor on the display screen of the display device. Moreover, since the mouse pad 1 is soft, the surface of the mouse pad is worn and damaged during use. Furthermore, part of the damaged mouse pad becomes dust and adheres to the ball, filling the irregularities on the ball surface, causing the ball to slip with the mouse pad, allowing the cursor on the display screen of the display device to move accurately. It had the drawback of disappearing.
