Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a coordinate indicating device (hereinafter referred to as a joystick) used, for example, in a graphic display; moving a cursor in a video game, or in a robot teaching device.

(b) Prior art and problems Most conventional joysticks have two degrees of freedom as shown in Figure 1. In this, the knob bar 1 is supported at the lower end on the stand 2, and the knob bar 1 is moved back and forth.
By adjusting the tilt angle in the left and right direction, 2
It was indicating the coordinate value of the dimension. As an extension of this, a three-degree-of-freedom type of joystick, as shown in Figure 2, has recently been used. This indicates the third coordinate by the rotation angle 4 of the knob 3 supported on the table 5. With this three-degree-of-freedom joystick, in order to specify any value in three dimensions at the same time, move the knob 3 back and forth.
It is necessary to rotate the tip of the knob bar 3 while tilting it left and right, but since the tilting operation and the rotation operation are different, a considerable amount of practice is required to operate it accurately. Also, the 3-degree-of-freedom joystick is 3
It is useful for indicating the value of each axis of a dimensional orthogonal coordinate system, but although the operation of tilting the knob 3 back and forth and left and right is similar to two-dimensional orthogonal coordinates, the rotation operation of the third axis is equivalent to orthogonal coordinates. Because it does not adjust to the position, it is difficult to turn it to the correct position, causing malfunction.

Furthermore, in recent robot motion teaching, coordinate instructions in many dimensions such as four and five dimensions are required. Therefore, joysticks with 2 to 3 degrees of freedom have been switched and used, or a plurality of joysticks have been used. However, in this case, there are disadvantages such as not being able to simultaneously specify coordinate values of many dimensions, or because both hands are occupied by the joystick operation, making it impossible to perform other switch operations.

(c) Purpose of the invention The purpose of the invention is to:
It is an object of the present invention to provide a coordinate indicating device capable of indicating multidimensional coordinate values without using a plurality of joysticks.

(d) Structure of the invention According to the invention, this purpose is to provide a coordinate indicating device that detects the operation position of a knob bar with a detector and indicates the coordinate position, and the said knob bar is moved in the X and Y directions. This is achieved by providing a coordinate indicating device characterized in that a mechanism for parallel movement and a mechanism for movement in the front-rear and left-right directions using the lower end support of the knob bar as a fulcrum are fixed to the upper part of the mechanism.

(e) Embodiments of the invention Hereinafter, embodiments of the invention will be described in detail using drawings.

FIG. 3 shows a perspective view of an embodiment of the coordinate indicating device of the present invention.

In the figure, 15 is a knob bar, 16 is a two-degree-of-freedom joystick similar to the conventional one, 17 and 18 are potentiometers, 19 and 20 are rails, and 21 and 2
2 is a moving table, and 23 is a table. The two-degree-of-freedom joystick 16 is fixed to the moving table 21, the potentiometer 17 and the rail 19 are fixed to the moving table 22, and the potentiometer 18 and the rail 20 are fixed to the moving table 23.
is fixed. The moving table 21 moves on the rail 19, and the potentiometer 17 detects its position. The moving table 22 moves on the rail 20, and the potentiometer 18 detects its position.

To operate this joystick 7, hold a knob 15, for example, as shown in FIG. That is, the upper part of the grip bar 15 is held between the thumb 24 and the index finger 25, and the middle of the grip stick 15 is held between the middle finger 26 and the ring finger 27. By holding the lower end of the knob 15 in one place with the middle finger 26 and ring finger 27 and moving the tip of the knob 15 back and forth and left and right with the thumb 24 and index finger 25, the tip of the knob 15 can be tilted back and forth and left and right. . On the other hand, by simultaneously moving four fingers back and forth and left and right, the knob bar 15 can be moved in parallel back and forth and left and right. This allows you to specify four-dimensional coordinates with a single joystick.

Furthermore, if each potentiometer is provided with a suitable spring, when the knob bar 15 is released, it can be returned to its original position naturally. Furthermore, 2
Cover the part below the degree of freedom joystick 16 with a case, or place it at the bottom of the panel and attach the knob 1
By exposing only 5 to the outside, the beauty of the device can be maintained.

In addition, in this example, a potentiometer,
In place of 17 and 18, a linear encoder or the like that can detect movement on a straight line may be used.

Furthermore, by adding a one-dimensional joystick in which the knob 15 can move vertically in a straight line to the four-dimensional joystick shown in FIG. 3, five degrees of freedom can be indicated with one joystick. In addition, the third
If a rotation mechanism around the rod is added to the knob rod 15 of the four-dimensional joystick shown in the figure, it is naturally possible to specify five degrees of freedom.

(f) Effect of the invention As explained in detail above, the coordinate indicating device of the invention has a forward/backward and horizontal movement mechanism using the lower end support of the knob as a fulcrum, and a movement mechanism that moves the entire knob in parallel in the X and Y directions. By configuring the device to include the following, coordinate values in multiple directions can be indicated with one knob. Furthermore, since the knob bar can be moved in parallel without rotation, it is similar to two-dimensional orthogonal coordinates, making it easy to use and preventing malfunctions.
