Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a three-dimensional joystick for controlling three-dimensional social display.
・ [Technical background of the invention and its problems] Joystick ili values are generally used to control the artist display, but conventional joystick devices are only used to specify two-dimensional positions and control the display. In recent years, it has become possible to display three-dimensional mats on the display. Therefore, even if the joystick V & position has a conventional two-dimensional displacement function,
It is possible to specify the position of the IS, but if the position can be specified using the 3-dimensional three axes (x @, y axis, Z axis) I8, it is possible to specify the position according to the operator's vision. Since the operation becomes possible, it is possible to improve the operability. However, until now, a simple joystick device having a three-dimensional displacement function has not been provided.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and an object thereof is to provide a joystick device having a three-dimensional displacement function at a low cost. [Summary of the Invention] To achieve the above object.

, [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view showing one embodiment of a three-dimensional joystick position. In FIG. 1, the three-dimensional joystick device includes a joystick 2 protruding from a housing 1, a joystick 2 housed within the housing 1, and a volume that adjusts to a three-dimensional axial movement position by operating the joystick 2. X-axis volume 3 (hereinafter referred to as X
Axis VR! : Iuo and below), Y-axis VR4, 2-axis V
It consists of R5 Toka. The joystick 2 is housed in a housing 1 and is attached to a workpiece 11, the details of which will be described later, so as to be slidable in the direction of arrow Z in the figure. @11 and the holder 1112, which will be described in detail later, are connected by a universal joint, for example, the final ball 11a of the target m1lils 11 is rotatably housed in the holder 11112 ◎ Also, the joystick 2 is connected to the housing. At appropriate positions within 1, the illustrated arrows Y and X
A guide shaft 9, the details of which will be described later, is installed along the direction f'.
It is inserted with a slight gap between @, 9α and guide shaft 1011.10g.◎6 is the above-mentioned

The slidable member 11 will be explained with reference to all. In Figure lI2, the surface of the wall that is covered by mwb1111 is -
st cut] cut out to make a sliding groove 11h, and the sliding groove #$11
The Z-axis VR5 is fixed at a position opposite to k, and the end of the joystick 2 into which the slidable part ILK is inserted! The holder 8112, which houses the ball 11a as a universal joint of the slider 111, which protrudes from the slider 111#I 11h and serves as the slider 5α of Z@VB2, is fixed to the support plate 6 with screws, for example. The operation of the device configured as described above will be explained.

For example, when specifying a predetermined position of a stereoscopic image on a display (not shown) by varying only in the *tx direction, hold one end of the joystick 2 that protrudes from the casing and
move in the direction. In this case, the joystick 2 is installed in the direction KG of the arrow X in the figure.
Since it moves at 0g, there is no displacement of the Y-axis VR4, and since one end of the joystick 20 inside the housing 1 is housed in the sliding part 11 via a universal joint, there is no displacement of the Z-axis VR5. . Therefore, the joystick 2 is designed to push only the guide shafts 9g and 9m installed in the direction of the arrow Y in the figure, so that the link plates 9 and 9 rotate around the fulcrum 7a, and the X-axis VR sliding axis 5 @ t-1 turn X @V
For this reason, the resistance value of Y
The position can be specified by displacing only the X-axis direction component without displacing the X-axis direction component. Similarly, by moving the joystick 2t in the direction of the arrow Y shown in the figure, the position can be specified by displacing only the X-axis component without displacing the Y-axis or Z-axis direction. In the case of displacement, by moving the joystick 2t along the axial direction of the joystick 2, the Z-axis VR is moved through the Z@VR slider Sat.
In this case, for example, the shimmy stick 2 is set perpendicular to the support plate 6.
Even if the joystick 2 is not moved in the axial direction, the angle of the joystick 2 with respect to the support plate 6 does not change, so no displacement is applied to the guide shafts 91, 1, and therefore the X-axis direction component It is interesting to displace only the Note that the joystick 2 does not need to be operated separately for each axis, for example, x, y.

It goes without saying that the X-axis direction component can be displaced at the same time.

It goes without saying that the present invention is not limited to the embodiments described above, but includes various modifications within the scope of the gist of the present invention. For example, the volume t was used to detect the position in each axis direction, but instead of the volume, a pulse generator or counter that generates pulses according to the set position may be used -zvho or joystick 2i! For example, as shown in figure W46, the guide shaft 10αe 9'' to be restrained along the ``axis'' has a circumferential surface KX of the shimmy stick 20, a length X 16α, 13At along the Y axis, and a length 13g, 13A.
Even if the guide shaft 104.9al is inserted, the shimmy stick 2 is inserted as shown in FIG.
4ri-st' Constructed with cylinders 14 at the four corners,
The guide shaft ioa, 9@ may be inserted between the four cylinders 140. In addition, the Z-axis position lE [detects the Z-axis VR5d, JiB (one child is installed in the Suffix 2O-1i$, the N-shift lB that stores the joystick 2)
11 may be equipped with a resistor in the sliding movement.
Furthermore, the universal joint composed of the sliding member 111it111 and the holding member 11i12 is not limited to the one that freely holds the ball 11- as in the above embodiment, but it goes without saying that other universal joints can be used. Next, the three-dimensional image position specification am for specifying a position in the three-dimensional image using the three-dimensional joystick f device will be explained. FIG. 5 is a block diagram showing an example of the three-dimensional image position specification am.
