Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mouse pad, and more particularly, to a mouse pad having an operation surface for moving a mouse of an input / output device used in a personal computer or an intelligent terminal device.

[0002]

[Prior art]

 For example, the mouse, which is an input / output device (pointing device) used in personal computers and intelligent terminal devices, is grasped as if the operator wraps it around with his / her hand, and the operator touches it on the operation surface such as a desk in a diagonal direction. When it is moved to, the movement direction and the movement amount corresponding to the distance are output to the display device, and the cursor position is indicated on the screen of the display device.

By the way, the above-mentioned mouse has a structure in which a ball is rotatably arranged in a state in which the ball is projected on the surface side that comes into contact with the operation surface, and the moving direction and the moving amount are detected by the rotation of the ball. Have. Therefore, on the desk where the mouse is operated, it may be difficult to point the cursor position to a desired point on the screen of the display device even though the ball is slipping and the mouse is moved. .

Therefore, a sheet-shaped member called a mouse pad is laid on the desk and the mouse is operated on the mouse pad. In this mouse pad, the operation surface of the mouse has a rough surface, and the contact resistance with the mouse ball is increased. As a result, when the mouse is operated on the mouse pad, the ball does not slip when the mouse is moved, and the ball surely rotates and the screen of the display device is displayed according to the moving direction and the moving amount. It becomes easy to accurately specify the cursor position of.

The bottom surface of the mouse pad, which is in contact with the desk, also has a rough surface with a large contact resistance with the desk so that the mouse pad does not slip on the desk.

[0006]

[Problems to be solved by the device]

 By the way, when a human arm is placed on a desk in a relaxed state, the forearm does not twist and the palm is in a natural posture in which the palm is directed obliquely downward. However, since the mouse operation described above is performed on the horizontal operation surface of the mouse pad placed on the desk, when the operator grips the mouse to be moved on the horizontal operation surface, the forearm is twisted. The palm of the hand is in an unnatural posture, with the palm facing down.

By continuing such an unnatural posture for a long time, fatigue is accumulated and pain and dullness are felt. In this way, the “cervical-shoulder-arm disorder syndrome”, in which fatigue accumulates and pains appear somewhere from the fingers to the shoulders, is becoming a problem as an occupational disease.

Therefore, the present invention has been proposed in view of the above problems, and an object of the present invention is to provide a mouse pad capable of reducing operator fatigue due to long-term mouse operation. .

[0009]

[Means for Solving the Problems]

 As a technical means for achieving the above object, the present invention provides an operator with an operation surface for moving a mouse, which is an input / output device such as a computer, in a front-back, left-right, and diagonal directions with respect to a bottom surface placed on a desk or the like. While holding the mouse with the palm of the hand, the operator's forearm is not twisted, the palm is tilted at an angle that points diagonally downward, and the tilting direction can be set in any direction. To do.

In the present invention, it is desirable that the inclination direction be substantially orthogonal to the direction in which the forearm of the operator extends, because fatigue of the operator can be further reduced.

[0011]

[Embodiment of the invention]

 Embodiments of the present invention are shown in FIGS. 1 to 6 and described in detail below.

As a feature of the present invention, as shown in FIGS. 1 to 3, an operator operates an operation surface 5 for moving a mouse 4 with respect to a bottom surface 3 placed on a desk (not shown) and an operator's palm 8 With the mouse 4 held in place, the operator's forearm 6 is not twisted and the palm 8 is inclined at an angle θ that is directed obliquely downward so that the operator can place it so that the inclination direction is in any direction. is there. The inclination angle described above is preferably about 5 ° to 20 °.

The mouse pad 1 of the embodiment shown in FIG. 1 has a bottom surface 3 that contacts a horizontal desk on which a personal computer or the like is placed, and an operation surface 5 that is inclined with respect to the bottom surface 3 and that moves the mouse 4. Since the bottom surface 3 forms a rough surface having a large contact resistance with the desk 2 in order to come into contact with the desk 2, the operation surface 5 also comes into contact with a rotatable ball protruding from the bottom surface of the mouse 4. Then, a rough surface with a large contact resistance with the ball is formed.

The usage pattern of the mouse pad 1 of the present invention will be described in detail below.

First, as described above, the operator holds the mouse 4 with the palm 8, and the operator's forearm 6 is not twisted, and the palm 8 is provided with the operation surface 5 inclined at an angle θ that is directed obliquely downward. The mouse pad 1 is positioned and arranged on the desk so that the inclination direction thereof is substantially orthogonal to the direction in which the operator's forearm 6 extends. This positioning is possible because the bottom surface 3 of the mouse pad 1 is a rough surface having a large contact resistance with the desk.

If the operator places the mouse 4 on the operation surface 5 of the mouse pad 1 and grips the thumb 7 a and the little finger 7 b with the palm 8 so as to contact the operation surface 5, the operation surface 5 of the mouse pad 1 Is inclined at the angle θ as described above, the forearm 6 of the operator who holds the mouse 4 does not twist and the palm 8 can be held in a natural posture with the palm 8 facing diagonally downward. The mouse 4 can be moved diagonally forward, backward, leftward and rightward in a natural posture. At this time, since the operation surface 5 of the mouse pad 1 is inclined only at a small angle, the mouse 4 is positioned and fixed without sliding down the inclination due to friction with the operation surface 5.

Since the mouse pad 1 is only positioned and placed on the desk only by the contact resistance with the desk as described above, the mouse pad 1 is moved to change the tilt direction of the operation surface 5. The mouse pad 1 can be positioned and placed so as to face in any direction. For example, as shown in FIG. 4, the mouse pad 1 is placed so that the inclination direction of the operation surface 5 makes an acute angle with the direction in which the operator's forearm 6 extends. It can also be placed diagonally on the desk.

In this way, the operator can change the direction of the mouse pad 1 to various directions on the desk so that the inclination direction of the operation surface 5 of the mouse pad 1 can be appropriately changed as necessary. As a result, the palm 8 of the operator who holds the mouse 4 does not always keep pointing in a certain direction for a long time, and the mouse 8 can be operated with the palm 8 pointing in various directions. Is suitable.

Further, as shown in FIGS. 5 and 6, a plurality (two in the figure) of the pad units 9, 10 (the tilt angle θ of the operation surface)₁, Θ_TwoIt is also possible to construct a mouse pad by arbitrarily combining and stacking the above) regardless of its size or shape. In the mouse pad 1 including the pads 9 and 10, the tilt angle of the operation surface 5 of the uppermost layer is such that the operator's forearm 6 is not twisted while the operator holds the mouse 4 with the palm 8 Desired angle θ (tilt angle θ) ₁ + Θ_Two).

At this time, since the bottom surface 11 and the operation surface 12 contacting the individual pad units 9 and 10 are both rough surfaces having a large contact resistance, the pad units 9 and 10 are displaced from each other due to their contact resistance. There is nothing to do. When a plurality of pads alone are laminated, the combination of the number, the inclination angle and the inclination direction is arbitrary.

As described above, by stacking a plurality of pads alone by stacking them and by tilting the operation surface of the uppermost layer at a desired angle, a mouse having a desired operation surface can be obtained only by combining a plurality of pads alone. Since the pad can be realized, it is possible to quickly and accurately respond to the operator's request.

[0022]

[Effect of the invention]

 According to the present invention, the operator holds the mouse with the palm on the operation surface for moving the mouse, which is an input / output device such as a computer, in the front-rear, left-right, and diagonal directions with respect to the bottom surface placed on the desk or the like. The operator's forearm holding the mouse can be twisted because the operator's forearm is not twisted, and the palm is tilted at an angle that points diagonally downward, and it can be placed so that the tilt direction is in any direction. Instead, it can be operated with the palm of the hand in a natural posture, and operator fatigue can be dramatically reduced, and the incidence of occupational diseases such as the "neck and shoulder arm disorder syndrome" can be suppressed. In addition, it is possible to operate the mouse by pointing the palm of the operator who holds the mouse in various directions, which is a refreshing feeling when the mouse is operated for a long time.
