Description

[Detailed description of the invention] [Industrial application field] This invention can be used, for example, to measure the position of a certain object, to control the position of a moving object in a precision machine tool, or to control the position of a cursor in a display device. The present invention relates to a joystick controller suitable for use.

[Summary of the idea]

This idea is based on a joystick controller in which the operating shaft is supported at the center of the pivot so that it can be tilted and rotated in all directions. A plate and an inner shaft means that selectively engages with the tip thereof are provided integrally with the operating shaft, and by operating the inner shaft means, the tilting/rotation range of the operating shaft is limited or canceled. This is designed to save time and effort when switching the rotation range and to reduce costs.

[Conventional technology]

As a conventional joystick controller in which a variable resistor or the like is integrally incorporated as a converter, the one shown in FIGS. 7 and 8, for example, has been proposed. That is, FIG. 7 is a schematic cross-sectional view of a conventional joystick controller, and FIG. 8 is a schematic view of the controller as seen from below with the lid removed.

In the figure, reference numeral 1 denotes an operation shaft, which consists of an extension shaft 2 and a knob 3. A spherical ball 4 is fixed by passing through the center of the extension shaft 2 of the operation shaft 1. 5 is tilted and rotatably fixed at the center by an upper holding plate 6 and a lower holding plate 7, and by operating the knob 3 of the operating shaft 1, each swing engages with the tip of the extension shaft 2. By rotating the plates 8 and 9, the shafts of the transducers 10 and 11, such as variable resistors, are rotated, and an electrical output corresponding to the tilt/rotation angle of the operating shaft 1 is transmitted to each transducer 1.
I am trying to take it out from 0 and 11. In addition,
12 is a lid attached to the lower side of the pivot 5.

Here, the tilt angle of the operating shaft 1 is limited by applying the circumferential surface of the extension shaft 2 to the inclined surface of the upper holding plate 6, so the opening of the upper holding plate 6 is formed into a predetermined shape such as circular or square. Alternatively, a plate for restricting tilting and rotation may be attached to the upper side of the upper holding plate 6 to restrict the tilting/rotation to one direction (X-axis direction and Y-axis direction) or two directions (X-axis direction and Y-axis direction). It is used.

[The problem that the idea attempts to solve]

However, in the case of the conventional joystick controller as described above, when you want to use a controller that can be tilted and rotated in all directions as a type that can be operated in a predetermined direction such as one or two directions, the upper holding plate or the tilting and rotation are required each time. It is necessary to replace the rotation limiting plate, which is time consuming and expensive.

This invention was devised in view of the above, and provides an inexpensive joystick controller that can be easily operated in a predetermined direction without much effort.

[Means to solve the problem]

The joystick controller according to this invention has an operating shaft 20 that can be tilted in all directions at the center of the pivot 5.
In a freely rotatably supported joystick controller, an inclination/rotation limiting plate 25 is provided apart from the tip of the operating shaft 20, and the tip passes through the inside of the operating shaft 20, so that the tip thereof can be selectively tilted. - Inner shaft means 21 and 24 that engage with the rotation limiting plate 25 are provided, and the tilting and rotation range of the operating shaft 20 is restricted or canceled by operating the inner shaft means 21 and 24.

[Effect]

An inner shaft means 2 that penetrates the inside of the operating shaft 20 and whose tip portion selectively engages with the tilt/rotation restriction plate 25.
1 and 24 are provided. And push button 2 of the inner shaft means
When 4 is pressed, the tip of the inner shaft 21 engages with the guide groove 26 of the tilt/rotation limiting plate 25, the tilt/rotation range is restricted, and the operating shaft 20 moves in a predetermined direction.
If the push button 24 is not pressed, the engagement between the tip of the inner shaft 21 and the guide groove 26 of the tilting/rotation limiting plate 25 is released, and the operating shaft 20 can be tilted and rotated in all directions. As a result, there is no need to replace the upper holding plate or the tilting/rotation limiting plate as in the past, which saves time and costs.

〔Example〕

Hereinafter, one embodiment of this invention will be described in detail based on FIGS. 1 to 6. In FIGS. 1 to 6, parts corresponding to those in FIGS. 7 and 8 are denoted by the same reference numerals, and detailed explanation thereof will be omitted.

In this embodiment, the operating shaft 20 is substantially composed of a double shaft consisting of an inner shaft 21 and an outer shaft 22, and the outer shaft 22 and a knob 23 attached to one end thereof are inserted through the outer shaft 22 from top to bottom. An inner shaft 21 is provided so as to be movable in the axial direction, and a push button 24 is attached to one end thereof.
The center portion of the outer shaft 22 is fixed to the ball 4.

In addition, a tilt/rotation restriction plate 25 is provided at the bottom of the pivot body 5.
will be established. This tilt/rotation limiting plate 25 has guide grooves 26 in two directions (X-axis direction and Y-axis direction), as shown in FIG. 4, for example.

Further, the inner shaft 21 and the outer shaft 22 are attached as shown in FIGS. 5 and 6. That is, the sixth
As shown in FIG.
As shown in the figure, V-notches 21a are provided on the top and bottom at predetermined intervals. Further, a C ring 27 is attached near the upper side of the inner shaft 21, and this C ring 27 and the outer shaft 2
A compression coil spring 28 is inserted between the upper end of 2.

When the push button 24 is pushed in against the elastic force of the compression coil spring 28 as shown in FIG.
The engagement protrusion 22a is located in the V-notch 2 on the upper side of the inner shaft 21.
1a, movement of the inner shaft 21 is temporarily locked. At this time, as shown in FIG. 1, the tip of the inner shaft 21 largely protrudes from the outer shaft 22 and fits into the guide groove 26 of the tilt/rotation limiting plate 25, thereby limiting the operating range of the operating shaft 20. . In other words,
At this time, the operating range of the operating shaft 20 is limited to two directions: the X-axis direction and the Y-axis direction.

Next, when the push button 24 is pushed back as shown in FIG. 6, the inner shaft 21 is pushed upward by the compression coil spring 28, and the engagement protrusion 22a of the outer shaft 22 engages with the V-notch 21a on the lower side of the inner shaft 21. The movement of the inner shaft 21 stops. At this time, the tip of the inner shaft 21 is connected to the guide groove 25 of the tilt/rotation limiting plate 25 as shown in FIG.
This releases the restriction on the operating range of the operating shaft 20. In other words, the operating range of the operating shaft 20 can be tilted and rotated in all directions at this time.

In addition, in the above-mentioned embodiment, the tilt/rotation limiting plate 25
Although the operating range of the operating shaft 20 has been described in the case of two directions, it is not limited to this, and may be one direction or multiple directions of two or more directions.

[Effect of idea]

As mentioned above, according to this invention, the tilting/rotation limiting plate is pre-assembled into the pivot body, and the operating range of the operating button can be easily changed by operating the push button on the operating shaft. There is no need to switch to an upper holding plate or a tilting/rotation limiting plate as shown in the figure, which saves time and effort and reduces costs.
