JPS6180326A - coordinate input device - Google Patents

Abstract

PURPOSE:To attain fine positional control and independent control for X and Y coordinates by forming a track ball and X and Y direction setting keys or the line on a coordinate input device. CONSTITUTION:The coordinate input device is constituted of a substrate 10, a track ball 12, X and Y direction setting keys 14, ten keys 16, an operation key 18 to be used when an input set value by a preceding key such as the track ball 12 is to be inputted as a relative value, and an operation key 20 to be used when said value is to be inputted as an absolute value. After executing rough positioning by the track ball 12, fine displacement or one-way positioning can be attained by the keys 14 or the ten keys 16.

Description

[Detailed description of the invention] (a) Industrial application field The great invention is used in the field of inputting digital data, particularly coordinate data.

The present invention relates to a coordinate input device used as a peripheral device of a computer.

(b) Prior Art Coordinate input devices have been known as peripheral devices for computer devices, such as trackballs and joystates. These input devices allow the operator to
It is convenient because it can be used while looking at a display device such as
Also, it is difficult to control the amount and the minute amount. For example, when using a trackball, when using the trackball for the first time, check the positions of both XX and Y, and then using the trackball for the second time to slightly deviate the b deviation of X, Y in one direction. Both XXY positions moved at the same time! ,l,-1
However, it is difficult to operate, as it requires several uses to fix the cursor at a desired position, for example.

(C) Purpose The purpose of the great invention is to provide a coordinate input device that takes advantage of the convenience of a trackball and has key combinations that enable minute position control and single X, Y coordinate control. The goal is to provide the following.

B) Structure The above purpose is to have a trackball, XXY direction setting keys, numeric keypad, keys to be operated when you want to input set coordinates as relative values, and keys to be operated when you want to input set coordinates as absolute values. This can be achieved by doing so.

In other words, rough positioning is performed by operating the trackball, and the input settings at that time are set as relative values.
By using the X, Y direction setting keys and the numeric keypad, you can make a slight deviation.On the other hand, when the coordinate position is known from the beginning,
There is also a numeric keypad so you can use it.

(e) Examples A preferred embodiment of the invention will be explained based on the drawings.

The drawing is a plan view showing one embodiment.

10 is the base, 12 is the trackball, 14 is the XXY direction setting key, 16 is the numeric keypad, 18 is the trackball 12
The key 20 is operated when the user wants to input the set value input by the preceding key as a relative value, and the key 20 is operated when the user wants to input the set value as an absolute value.

For example, if the operator wishes to move the coordinates by 12 in the 10X direction after performing large-scale positioning using the trackball 12, the operator selects Re1atjve (!Jlatip).
To set the mode, press the key ■8, and then touch the ■, 2, and → keys. Also, when directly calculating coordinates, for example, if you want to set X-125, Y = 347, use Absolute mode.
Just press the key 20 and input 1.2.5, →, 3.4.7, ↑. Note that the direction setting key 14 may have a function so that it is used before using the numeric keypad 16.

The functional configuration of the coordinate input device is 1/-1°, which is not specified unless the invention is made.
6 is connected to the computer via the encoder, and the other keys 14, 18, and 20 are so that their signals are input to the computer, and the -cut operation is performed by software means of the computer. good. In addition, the board 10 itself has memory, arithmetic units, etc., and when each key such as the trackball 12 is touched, these board circuits operate, and the output value is 1.
The information may be input to the computer through one port.

Note that the illustrated example shows the minimum configuration,
Be sure to press it at the beginning of your input, or use it in combination with other keys as needed, such as the reset key.

(f) The highly effective invention has the effect that coordinate setting can be performed relatively quickly and accurately since minute displacement and unidirectional position setting are possible when the function of the trackball is to be utilized.
