Interface part 25 transmits the outputs of output parts 24a and 24b together with ON/OFF signals of operation switches 5, 6 to an information processing device.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a coordinate position input device used in connection with an information processing device such as a personal computer.

(Background of the Invention) As is well known, devices used for inputting coordinate positions into information processing devices such as personal computers include what is commonly called a mouse, a track board, and a mouse.
There are various types of devices, such as touch panels, touch panels, tablets, and joysticks, and they are selected and used depending on the purpose, such as cursor operation or simple graphic input.

Among these, the mouse is more commonly used and widely used than other coordinate position input devices because of its simplicity and ease of use.

However, the following drawbacks have been pointed out to the mouse:
Improvement is desired.

First, since the Il device is operated as a whole by moving, an operation plane of at least the size of an A4 sheet of paper is required, and it is necessary to secure this area on the operation table on the information processing device side. However, it is well known that securing these nine areas is often difficult.

Furthermore, if the area is partitioned by a frame with steps on its outer periphery, &lI convention ('1) will be added to the operating position, reducing the operability by half.

In addition, since it is operated by an operator,
Long-term use causes operator fatigue.

(Objective of the Invention) The present invention solves the space problem without losing the operability and convenience inherent in the mouse.
An object of the present invention is to provide a new coordinate position input device that can significantly reduce fatigue accumulation.

(Structure and Effects of the Invention) In order to achieve the above object, a coordinate position input device according to the present invention includes a stage section set on a flat surface, and a coordinate position input device placed on the top surface of the stage section. an operating section that is slidable in any direction with a predetermined position as an origin position and that performs a self-return operation from the displaced position to the origin position; a position detection means for detecting the displacement position of the operating section; and the origin position. The present invention is characterized by comprising displacement amount converting means for converting the displacement position from to the displacement position detected by the position detecting means into each axis component of coordinate axes intersecting at a constant angle by N1.

According to this article, the coordinate position input device is used by setting it in a fixed position and sliding only the operation part by a predetermined amount, so the space that needs to be prepared is considerably more than when using a mouse. Something small is fine.

In addition, all you have to do is simply displace the operating section, and once the operation is complete and you let go of the operating section, the operating section will return to its original position by itself, making it easy to use and easy to use. Accumulation of fatigue is significantly reduced compared to mice.

(Description of Embodiments) FIG. 1 is a schematic external view of the coordinate position input device according to the present invention, in which (A> shows the first embodiment, and FIG. 1B shows the second embodiment).
Examples are shown below.

In the figure, this coordinate position input device consists of a stage part 1 and an operation part 2 placed on the top surface of this stage part 1. A connection cord (not shown) is pulled out from the stage part 1, and a connection cord (not shown) is pulled out from the stage part 1. It can be connected to an information processing device.

The stage portion 1 has a support 3 made of rubber material protruding from the back surface thereof, and is set at an arbitrary position on the table surface 4 by this branch. Further, the center position of the upper surface of the stage section 1 is defined as the origin position.

The operating section 2 is slidably displaceable in any direction from the original position, and is adapted to self-return from the displaced position to the original position.

In other words, when the operating section 2 is moved in any direction and then released, it automatically returns to the original position.

Further, this operation unit 2 is provided with two operation switches 5.6, and by operating the operation switches 5.6, the output signal of the input device is read by the information processing device.

As shown in the figure, in the coordinate position input device according to the first embodiment, the outer shape of the stage section 1 is the same as that of the operating section 2. In the coordinate position input device according to the second embodiment, the outer shape of the operating section 2 is larger than the outer shape of the stage section 1.

Next, the electrical configuration will be explained according to FIG.

The displacement amount detection unit 21 detects the displacement position where the operation unit 2 is mechanically displaced from the origin position, for example, optically or by a strain gauge method, and detects the displacement ω by the X-direction component extraction unit 2.
2a and the Y-direction component extractor 22b, respectively.

The extraction units 22a and 22b extract each axis component (X, Y
), one of them is extracted and the signal converter 2
3a and 23b, respectively.

The signal converters 23a and 23b convert the input component displacement amounts into corresponding analog signals of a predetermined level using, for example, a potentiometer system, and output the digital output parts 24a and 23b.
24b, respectively.

The digital output units 24a and 24b convert the input analog signal into a pulse train having a pulse frequency corresponding to the level, for example, and output it while the input signal is present.

The interface section 25 has digital output sections 24a and 24.
When the operation switch 5.6 is turned on, the output of b is transmitted to the information processing device together with the 10FF signal.

Thereby, in the information processing device, while the operation section 2 is being displaced, the frequency of the incoming cabling sequence changes correspondingly, so that the coordinate point can be moved.

In addition, in the above electrical planting, the digital output section 24a
, 24b and the interface section 25 may be separate devices as an interface between this device and the information processing device, or all of their functions may be performed on the information processing device side.

Further, in the above embodiment, two operation switches are provided, but it is of course possible to use only one operation switch, or the number of #J may be further increased to give meaning to each switch operation. You can do it like this.
