BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. The present invention will be described below with reference to the drawings.
FIG. 4 shows a block circuit diagram of a game machine or a computer, and a display example of the display device 25. In the display device 25 such as a CRT or a liquid crystal, right-angle coordinates are also shown for explanation. However,
Generally, rectangular coordinates are not displayed on an actual game screen.

An image generation circuit 80 as a game generation unit generates an image of game software, and an image signal is sent to an image display control circuit 90 of a display control unit. The joystick 1 generates position data of the operation input system, and outputs an X-axis volume 10 of the first sensor for movement, a Y-axis volume 20 of the second sensor, a Z-axis volume 30 of the third sensor, and rotation. A first volume X-axis rotation volume 15, a second volume Y-axis rotation volume 16, and a third volume Z-axis rotation volume 17.

The signals from these sensors and the volume are sent to an image display control circuit 90, added to the image data of the video of the game software, and added to the display unit 25 of the display unit.
Sent to

The three-dimensional space displayed on the display device 25 is
It has XYZ axes and rotation vector coordinates XrYrZr axes,
The character 26 is displayed. X axis volume 10
In the three-dimensional space, the characters 26 move in the XYZ three-dimensional space.

The change in the values of the X-axis rotation volume 15, the Y-axis rotation volume 16, and the Z-axis rotation volume 17 indicates that in a three-dimensional space, the character 26 rotates around the rotation vector coordinates XrYrZr axis and changes its direction. Change.

When the values of these sensors and volume are continuously changed, the character 26 rotates while moving, moves while rotating, and changes direction in the three-dimensional space. Next, a configuration in which these sensors and volumes are incorporated in the joystick 12 will be described with reference to FIGS.

FIG. 1 schematically shows the entire image of the joystick 12 of the present application. First, a base 2 which is a first operation rod of a joystick 12 is rotatably provided on a base 1 which is a box-shaped fixing portion. The base 2 is a cylindrical column having a hollow hole 8. The main trunk 3, which is a rod-like and slightly thin second operation rod, is slidably inserted into the hollow hole 8.

At the tip of the main trunk 3, a spherical shell 5, which is a hollow holding portion of a size that can be held by a human hand, is attached, and the spherical shell 5 is cut out to near the upper half. In the hollow of the spherical shell 5, a spherical body 6, which is a slightly small-diameter spherical part, is rotatably held, and the cutout range of the spherical shell 5 is such that the spherical body 6 does not fall off the spherical shell 5.

The spherical shell 5 has such a thickness that it can be processed, and a large number of hemispherical small holes are formed by being dispersed inside the spherical shell 5. A ball bearing 7 is fitted into each of these small holes, and a spherical body 5 is formed. 6 is rotatably held in the spherical shell 5 via a ball bearing 7.

In FIG. 3, an indirect sphere 13 is provided at the lower end of the main body 2, and a X
Axis volume 10 and Y-axis volume 20 of the second sensor
And are arranged. The X-axis volume 10 and the Y-axis volume 20 are rotation sensors and have rotation axes A and B, and these rotation axes A and B intersect each other.

In a state where the base 2 is assembled to the base 1, the indirect sphere 13 comes into contact with the X-axis volume 10 and the Y-axis volume 20, and when the base 2 is rotated with respect to the base 1, the indirect sphere 13 also rotates. , X-axis volume 10 and Y-axis volume 20 rotate due to the reaction, and the output values of these rotation sensors change.

As shown in FIG. 2, a Z-axis volume 30 of the third sensor is arranged between the main trunk 2 and the main trunk 3,
When the main trunk 3 is slid vertically with respect to the main trunk 2, the Z-axis volume 30 rotates and its output value changes. Changes in the outputs of the X-axis volume 10, the Y-axis volume 20, and the Z-axis volume 30 move the character 26 in the XYZ directions in the three-dimensional space on the display device 25 in FIG.

Next, in FIG. 1, the X-axis rotary volume 15 of the first volume and the Y-axis of the second volume are arranged so that the rotation axes intersect each other between the spherical shell 5 and the spherical portion 6 of the holding portion. A rotary volume 16 and a third volume Z-axis rotary volume 17 are arranged. The X-axis rotation volume 15, Y-axis rotation volume 16, and Z-axis rotation volume 17 are rotation sensors, and have rotation axes D, E, and F. These rotation axes D, E, and F are three-dimensionally connected to each other. Intersect.

The spherical portion 6 in the spherical shell 5 includes an X-axis rotary volume 15, a Y-axis rotary volume 16, and a Z-axis rotary volume 1.
When the ball 6 rotates, the X-axis rotary volume 15, the Y-axis rotary volume 16, and the Z-axis rotary volume 17 rotate around their respective axes.

When the spherical portion 6 rotates, the X-axis rotation volume 15, the Y-axis rotation volume 16, and the Z-axis rotation volume 1
7 changes. The change in the output values of the X-axis rotation volume 15, the Y-axis rotation volume 16, and the Z-axis rotation volume 17 causes the character 26 to rotate around the rotation vector coordinate Xr, Yr, Zr axis in the three-dimensional space.

The joystick 12 is provided with a start key 9 and a selection key 11 necessary for the game. An operation when the character 26 is displayed in a three-dimensional space having XYZ axes on the screen of the display device 15 in FIG. 4 will be considered.

When the user grips the spherical shell 5 of the table 1 and swings the trunk 2 with respect to the table 1, the values of the X-axis volume 10 and the Y-axis volume 20 fluctuate. 90.

The display control circuit 90 includes an image generation circuit 80
Image data of the three-dimensional character 26 is also input, and the values of the volumes 10 and 20 become the position data of the character 26, the X-axis volume 10 and the Y-axis volume 20.
In the three-dimensional space, the character 26
Move in the plane.

At the same time, when the spherical shell 5 is gripped and the main trunk 3 is pushed or pulled with respect to the main trunk 2 and is slid,
The value of the Z-axis volume 30 also changes, and in the three-dimensional space, the character 26 moves in the Z-axis direction in addition to the XY plane.

Next, when the spherical body 6 is rotated through the ball bearings 7 in the spherical shell 5 using the fingers while holding the spherical shell 5, the X-axis rotary volume 15 and the Y-axis rotary volume 15 16 and the Z-axis rotary volume 17 also rotate,
The values of these rotary volumes 15, 16, 17 also change,
In the three-dimensional space, the character 26 rotates around the X axis, the Y axis, and the Z axis. The rotation direction, rotation angle, and speed of the character 26 can be set to a desired direction by adjusting the rotation speed of the sphere 6, and rotation can be given when necessary.

Accordingly, the sphere 6 rotates around the directions of the X-axis, the Y-axis, and the Z-axis while moving three-dimensionally in the XYZ space, and has six-dimensional degrees of freedom. According to the six-dimensional joystick of the present invention, in addition to the movement in the X-axis direction, the Y-axis direction, and the Z-axis direction, the direction of the character having the X-axis direction, the Y-axis direction, and the Z-axis direction as the rotation axis is changed. Is possible, the degree of freedom of movement of the character is greatly increased as compared with the conventional joystick, and a game with more variety than before can be created.
