JPS62293337A - Input device for one-dimensional coordinate - Google Patents

Abstract

PURPOSE:To avoid the soil of a display device and at the same time to improve the operability of the display device by providing a one-dimensional coordinate input device at a place in the vicinity of the display device and operating the coordinate device while looking at the display on the display device. CONSTITUTION:The one-dimensional coordinate input device 1 is set at the left side of the screen of a display device 2 and a switch 3 is provided under the device 1 to inform the end of movement to a processor. When a sliding volume 4 is used to the device 1, the voltage of a fixed level is applied to both ends of the volume 4 for the operation of the volume 4. Thus the voltage proportional to the shift value of a knob is produced at the output of the volume 4. This voltage is applied to an A/D converter 5 and the converter 5 delivers the digital value to be easily supplied to the processor. While either one of outputs is turned on with the operation of a sliding multi-spot switch 6. This multi-bit information is supplied to an encoder 7 and turned into the encoded digital output.

Description

[Detailed description of the invention] 3. Detailed description of the invention [Industrial application field] The present invention relates to an input device, and more particularly to a coordinate input device.

[Conventional technology]

Conventionally, a touch panel cursor key has been used as a coordinate input device.

[Problem that the invention seeks to solve]

The conventional touch panel described above has a mechanism in which the display device (display) is directly touched with the finger, so that: (1) the display device becomes dirty due to oil from the fingers, etc.;

2) The indicated part is hidden by fingers, etc., making it difficult to confirm.

3) Because there is a gap between the display part (light-emitting part) and the touch part, errors occur depending on the viewing angle.

4) Difficult to increase accuracy due to structure.

There is a drawback.

Furthermore, since the cursor keys are key switches, l) the amount of movement that can be made at a time (with one key action) is fixed.

2) The device to be operated (cursor keys) and the parts that actually move (
The cursor) is far away, making it difficult to operate.

There is a drawback.

[Means for solving problems]

In the present invention, a one-dimensional coordinate human-powered device is attached near a display device.

While looking at the display device, the operator specifies coordinates from a nearby one-dimensional coordinate input device. The processing device (computer, etc.) immediately reflects the input coordinates on the display device (moves the cursor or figure), thus allowing coordinates to be input while checking the response from the processing device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention.

A one-dimensional coordinate input device 1 is provided on the left side of the screen of a display device 2 (cathode ray tube, liquid crystal, etc.) for the processing device (computer), and a switch 3 below it for notifying the processing device of the end of movement (coordinate determination) is provided. It is provided. Note that the switch 3 may be unnecessary depending on the configuration.

FIGS. 2 to 4 are diagrams showing specific examples of realizing the one-dimensional coordinate input device l.

Figure 2 shows a variable resistor (volume) on the one-dimensional display device 1.
This is an example using . A constant voltage is applied to both ends of the slide type volumetric volume 4.

By operating this, a voltage proportional to the amount of movement of the knob is applied to the output of the volume 4. By applying this voltage to the input of the A/D converter 5, the A/D converter 5 outputs digital m (bit information) that is easy to input into a processing device.

FIG. 3 is an example using a multi-point switch. By operating the slide-type multi-point switch 6 having a large number of contacts, one of its outputs is turned on.

This multi-bit information is input to the encoder 7 and becomes an encoded digital output.

FIG. 4 shows an example in which a long touch pad 8 is used in place of the multi-point switch 6 shown in FIG. Since the principle is the same as that shown in FIG. 3, the explanation will be omitted.

〔Effect of the invention〕

As explained above, in the present invention, by attaching a one-dimensional coordinate input device near the display device, (1) the display device is not soiled.

(2) Accurate operation is possible because the coordinates can be checked on the display screen while being specified.

(3) You can specify any coordinates in one operation (however,
1-dimensional).

(4) Easy to understand operations.

In addition, when compared with a mouse, (5) no operation space is required.

There is also this effect.
