Abstract

PURPOSE:To vary the moving speed of a mouse cursor by arranging roughly the vertical and horizontal lines of a grid set on a pad at the center part of the grid and finely at the circumferential part of the grid respectively. CONSTITUTION:The vertical lines 3 of a grid are arranged in the rough intervals at the center part and in the fine intervals at the circumferential part of the grid respectively. Therefore the moved variable of a mouse cursor 9 is reduced on a display 6 when a mouse 4 is operated at the center part of a mouse pad 1. Thus a state suited to the fine jobs like the click of a fine line, etc., can be secured. Meanwhile the moved variable of the cursor 9 is increased on the display 6 when the mouse 4 is operated at the circumferential part of the pad 1. Thus the cursor 9 can be moved large on the display 6 with a small extent of movement of the mouse 4. Then the moving speed of the cursor 9 can be varied.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an optical mouse pad.

[Conventional technology]

Traditionally, optical mouse pads have a grid of vertical and horizontal lines arranged at equal intervals, so that no matter which part of the pad you use to move the mouse, the display will be the same when you move the mouse the same distance. The amount of movement of the upper mouse cursor was the same.

[Problem to be solved by the invention]

When moving the mouse cursor using the conventional optical mouse described above, there are two methods to change the ratio between the amount of mouse cursor movement and the amount of mouse movement.The first method is to use software. In this case, it is necessary to change the resolution setting of the mouse each time.Also, as a second method, when changing the resolution setting using the mouse itself or the hardware, an additional mechanism such as a changeover switch is required, which is expensive. There was a problem with becoming.

An object of the present invention is to be able to change the moving speed of a mouse cursor without the need to change the resolution setting of the mouse each time by changing the software, and without the need for additional mechanisms such as expensive changeover switches. Our goal is to provide optical mouse pads.

[Means to solve the problem]

The optical mouse pad of the present invention includes a plurality of vertical lines and a plurality of horizontal lines constituting a checkered pattern, and when a mouse is placed and moved and the bottom surface of the mouse crosses the vertical lines and horizontal lines,
the vertical and horizontal lines are optically read by the mouse;
In an optical mouse pad configured such that the amount of mouse movement is calculated from the read information, the line spacing between the plurality of vertical lines and the line spacing between the plurality of horizontal lines are each set as the distance from the center to the periphery increases. It is designed to be dense.

Further, the optical mouse pad of the present invention includes a plurality of vertical lines and a plurality of horizontal lines constituting a checkered pattern, and when a mouse is placed on the mouse pad and the bottom surface of the mouse crosses the vertical lines and the horizontal lines, In an optical mouse pad configured such that lines and horizontal lines are optically read by the mouse and the amount of movement of the mouse is calculated from the read information, the distance between the plurality of vertical lines and the distance between the plurality of horizontal lines The line spacing is configured to become sparser from the center to the periphery.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention, and FIG. 2 is a diagram showing the operation of an optical mouse used on the optical mouse pad shown in FIG. 1.

The optical mouse pad shown in FIG. 1 is constructed so that the line spacing between the plurality of vertical lines 3 and the line spacing between the plurality of horizontal lines 2 constituting the checkered stripes gradually become denser from the center toward the periphery. has been done.

Next, the operation will be explained.

In FIG. 2, when the mouse 4 moves on the mouse pad 1, light for reading is projected from the light emitting section 7, and the light is reflected by the surface of the mouse pad 1 and received by the light receiving section 8. Then, as the mouse 4 moves, when the light projected from the light emitting unit 7 is reflected by the vertical line 3 drawn on the mouse pad 1, the amount of reflection decreases. is detected and vertical line 3 is recognized. Then, the amount of movement of the mouse 4 at that position is measured from the mutual spacing between the recognized vertical lines, but the mouse control unit 5
Control is performed to move the mouse cursor 9 on the display θ in a direction corresponding to the movement of the mouse 4 by a distance corresponding to the measured amount of mouse movement.

At this time, as shown in FIG. 1, the vertical lines 3 of the grid are sparsely spaced in the center of the mouse pad 1 and densely spaced in the periphery. When the mouse 4 is operated, the amount of movement of the mouse cursor 9 on the display θ becomes small, making it suitable for narrow tasks such as clicking on thin lines. Also, mouse pad 1
When the mouse 4 is operated around the periphery of the mouse 4, the amount of movement of the mouse cursor 9 on the display 6 increases, and when it is desired to move the mouse cursor 9 on the display 6 by a large amount, it can be achieved with a small movement of the mouse 4.

In the above description, the mouse pad 1 has been described where the grid lines are spaced sparsely in the center and densely arranged in the periphery; Even if they are sparsely arranged in the center, the mouse 4
When you operate the mouse cursor 9 on the display e
When the mouse 4 is operated in the peripheral area, the amount of movement of the mouse cursor 8 becomes smaller, and the amount of movement of the mouse 4 becomes smaller.
The amount of movement of the mouse cursor θ relative to the movement of can be changed.

〔Effect of the invention〕

As explained above, the present invention allows the vertical and horizontal lines of the grid on the pad to be arranged sparsely in the center and densely in the periphery. This has the effect that the moving speed of the cursor can be changed.
