Abstract

PURPOSE:To reduce a software burden by providing a ball receiver in a roller part dedicated for X (Y)-direction detection besides ball receivers for X and Y-direction detection and moving a ball to desired ball receivers to input a moving locus only in the X (Y)-direction. CONSTITUTION:A pointing device is taken with a hand and is inclined to move a ball 1 to the lowest ball receiver. When the ball 1 is moved to an X and Y-direction detecting ball receiver 8, moving loca in X and Y directions are inputted by the movement of the pointing device because an X-direction roller part 4X1 and a Y-direction roller part 4Y1 are brought into contact wit the ball 1. When the ball 1 is moved to a ball receiver 8X dedicated for X-direction detection, only a roller pat 4X2 dedicated for X-direction detection is brought into contact with the ball 1; and therefore, when the pointing device is moved horizontally, the extent of movement in the Y direction is not detected but only the extent of movement in the X direction is detected by a detector 6X though movement components in the Y direction exist.

Description

[Detailed Description of the Invention] [Summary] In addition to the X-Y detection ball holder, a ball holder dedicated to X direction detection and a ball holder dedicated to Y direction detection are provided. When a ball enters the ball receiver, only the rotating shaft dedicated to X direction detection rotates, and when the ball enters the ball receiver dedicated to Y direction detection, only the rotating shaft dedicated to Y direction detection rotates. It is also possible to move the camera to the X direction and independently detect only the X direction or the Y direction.

[Technical field of invention]

C A D (computer aided d) is used to create blueprints etc. using an electronic computer.
A data tablet is known as a means for inputting a position in the X-Y directions in the X-Y direction system, but there are also other accessories such as a keyboard, a light pen, a cursor, a pointing device called a mouse, etc. is used. The present invention relates to this pointing device called a mouse.

This pointing device only needs to be moved on the desk.
Since you can input the moving direction and position, handling is convenient.

[Conventional technology]

Fig. 3 shows a conventional mechanical pointing device, in which (A) is an internal plan view, and (A) is an enlarged cross-sectional view of Rollo in Fig. (A). 1 is a ball built into the main body 2. In this ball 1, only a portion 1a protrudes downward from the bottom 3 of the main body 2.In other words, a spherical recess 8 is formed in the bottom 3, and a window hole 9 is made in the bottom, and the ball is inserted through this window hole. 1
A part 1a of is protruding downward. Therefore, when this device is moved on a desk, ball 1 rolls and the Y of ball 1
Rotating shafts 5x and 5y rotate via rollers 4X and 4y that are in contact with the side surfaces in the −X direction. In other words, when the ball 1 rolls, the roller 4X and the rotating shaft 5x rotate according to the amount of rolling in the X direction, and by detecting the amount of rotation of the rotating shaft 5X with the detector 6x, the pointing device moves in the X direction. The amount of movement can be detected. Similarly, by detecting the amount of rotation of the roller 4y and the rotating shaft 5y with the detector 6y, the amount of movement in the Y direction can be detected.

[Problem that the invention seeks to solve]

By the way, when drawing a horizontal line on the screen 10 as shown in FIG. 4, the mechanical pointing device is moved in the horizontal direction as shown by the arrow ax. At this time, it is necessary to set the vertical movement amount of the pointing device 11 to "0", but it is difficult to move the pointing device horizontally in a straight line accurately, and vertical movement (Y direction) is required.
V is unavoidable. Therefore, on the screen 10, 12
This results in a curved line as shown in . When drawing a vertical line, it is difficult to draw a straight line for the same reason.

Therefore, ■ Clear the counter that records the amount of movement in the pointing device with a switch, or ■ Create a program in advance on the host computer side to ignore the amount of change notified from the pointing device. Possible methods include:

However, in the configuration (2), the number of switches increases and the handling becomes complicated. Method (2) increases the burden on software processing.

A technical object of the present invention is to solve such problems with conventional pointing devices and to enable easy and reliable drawing of horizontal and vertical lines on a screen.

[Means for solving problems]

FIG. 1 is an internal perspective view illustrating the basic principle of a pointing device according to the present invention. In the present invention, in addition to the ball receiver 8 shown in FIG. 3, ball receivers 8X and 8y are further provided. The ball receivers 8X, 8y are adjacent to the ball receiver 8 via a low ridge-like portion 13,14. Like the ball receiver 8, the ball receivers 8x and 8y also have a window hole 9 in the center of the bottom, and the ball 1 also moves and rolls in these ball receivers 8x and 8y. A line connecting the center of the ball receiver 8X and the center of the ball receiver 8 is parallel to the rotation axis 5x, and a line connecting the center of the ball receiver 8y and the center of the ball receiver 8 is parallel to the rotation axis 5y. ing.

The rotating shaft 5X is provided with roller portions 4x2 with which the balls in the ball receiver 8x contact, and the rotating shaft 5y is provided with roller portions 4y2 with which the balls in the ball receiver 8y contact. Detectors 6x and 6y are attached to the rotating shafts 5x and 5y, respectively, and detect the amount of rotation of the respective rotating shafts 5x and 5y.

In addition, if ball 1 is sent in ball receiver 8,
The ball 1 contacts both the roller portions 4xl and 4yl in the X-Y direction.

[Effect]

The ball 1 is transferred to the lowest ball receiver by holding and tilting the pointing device. When the ball 1 is now moved to the X-Y direction detection ball receiver 8, both the X-direction roller part 4x1 and the Y-direction 30 part 4yl are in contact with the ball 1. The movement trajectory of is input and drawn on the screen.

When ball 1 is moved to ball receiver 8x dedicated to X direction detection,
Since only the roller portion 4x2 dedicated to X-direction detection contacts the ball 1, when the pointing device moves horizontally,
Even if there is a movement component in the Y direction, the amount of movement in the Y direction is not detected, and only the amount of movement in the X direction is detected by the detector 6X.

When the ball 1 is moved to the ball receiver 8y dedicated to Y-direction detection, only the roller part 4y2 dedicated to Y-direction detection comes into contact with the ball 1, so when the pointing device moves horizontally, there is a movement component in the X direction. Even if the object is moved, the amount of movement in the X direction is not detected, and only the amount of movement in the Y direction is detected by the detector 6y.

〔Example〕

Next, examples will be used to explain how the pointing device according to the present invention is actually implemented.

In this embodiment, in addition to the three ball receivers 8.8x and 8y, a fourth ball receiver 8f is provided.

This fourth ball receiver 8f is adjacent to both the ball receiver 8x dedicated for X-direction detection and the ball receiver 8y dedicated to Y-direction detection via a ridge-shaped portion 15.16.

It is not necessary to make a window hole 9 in the bottom of this ball receiver 8f.

As shown in FIG. 2, when the ball is transferred to the fourth ball receiver 8r where no roller part exists, even if the pointing device moves, the roller part does not come into contact with the ball 1, so the detector 6x
, 6y are not detected.

Further, if the window hole 9 is not made in the ball receiver 8f, the ball 1 will not rotate even if the pointing device moves.

In addition, each ball receiver 8.8x, 8y is formed deeply, and a window hole 17 is opened at a position corresponding to the side wall of the ball, and from the window hole I7: I 04X1 , 4x2.4yl , 4
It is also possible to expose the ball bearing y2 to the inside of the ball bearing, and to provide the ball bearing itself with bearings for the rotating shafts 5x and 5y.

〔Effect of the invention〕

As described above, according to the present invention, in addition to the ball receiver for detecting the X-Y direction, a ball receiver exclusively for detecting the X direction is also provided at the position where the roller section exclusively for detecting the X direction contacts, and a roller exclusively for detecting the Y direction. By installing ball receivers dedicated to Y-direction detection at the positions where the parts touch each other, and moving the ball to the desired ball receiver, in addition to the movement trajectory in the X-Y direction, only the X-direction can be detected.
Alternatively, a movement trajectory only in the Y direction can be input.

Moreover, it does not require any switch operations, is easy to handle, and does not require additional switches. Since unnecessary directions are not detected from the beginning, there is no increase in software burden.
