Abstract

PURPOSE:To facilitate the input operation and to reduce the fatigue of operation with simple constitution by judging the movement of coordinate and each instruction of coordinate input at present point of time in response to the operating state of two keys. CONSTITUTION:An input key 2 such as a character or the like, a coordinate moving key 3 and a coordinate input key 4 are arranged on a keyboard 1. When a switch 5 is turned on and the key 3 is depressed simultaneously, a microcomputer 7 stops the input of character data to judge the position of the key on the board 1, moves the coordinate of pertinent point to be inputted to display a cursor on a position of the screen of the display device corresponding to the moved coordinate. When the operator depresses the key 4 while observing the cursor, the coordinate of the cursor is inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an input device for a computer, etc., which allows the computer, etc. to instruct whether or not to display each point, and which is very large. When you have a display device with a large area (large screen, high-definition graphics, display), specify a certain point on the screen using the X and Y coordinates, and then select that point or that point. This relates to a coordinate input device that is often used when you want to input some data, commands, etc. to something displayed on the screen.

2. Description of the Related Art The most commonly used conventional coordinate input device is called a mouse because its external shape resembles a mouse. As the device 50 moves, the ball 51 inside the device 50 rotates between the bottom surface of the ball 61 and the top surface of the desk 62, and this rotation is expressed in the X coordinate direction and the Y coordinate direction. The system attempts to detect the coordinates that you want to input by performing separate detections in the coordinate directions. 63 is a cable.

Problems to be Solved by the Invention Since such conventional coordinate input devices are not on the keyboard but on the desk, it is common for users to keep their hands on the keyboard when entering data. , Next, when trying to input coordinates, take your hands off the keyboard, grab this coordinate input device, move the coordinate input device back and forth on the desk, and enter the desired coordinates. This requires the operator to move his/her hands over a large number of distances, which is very inconvenient for the operator, as he/she has to move his or her hands over a long distance and return his or her hands to the keyboard to press a key to continue reading the data. On the side, it's also tiring.

The present invention has been made in view of the above problems, and has a simple configuration. The operator does not have to take his hands off the keyboard at all, and the operator can move his hands on the keyboard as little distance as possible. It is an object of the present invention to provide a coordinate input device that can input X and Y coordinates, is very easy to operate, and is less tiring for the operator.

Means for Solving the Problems In order to solve the above problems, the present invention provides two keys on the keyboard, ``coordinate movement'' and ``coordinate input'', in addition to keys for inputting normal character data, etc. Furthermore, if you press a key corresponding to a normal character while holding down this "coordinate movement" key, the corresponding character data will not be considered to have been input from the key corresponding to this normal character. , depending on where that key is located on the entire keyboard, it is assumed that the coordinate movement in that direction has been instructed, and when this "coordinate input" key is pressed, the current coordinates will be displayed. A mechanism is provided to consider that an input has been specified.

Operation The present invention has the above-described configuration, so that when a key for inputting a normal character, etc. is pressed while pressing the "coordinate movement" key on the keyboard, it is not determined that the character, etc. has been input. , in the direction of that position, depending on the position of the currently pressed key on the keyboard that corresponds to that character, etc.
Move the coordinates of a point on the screen of a display device. In this way, you can input the desired coordinates by specifying the coordinates you want to input and then pressing the key that indicates "coordinate input", which is also a key on the keyboard. , there is no need to take your hands off the keyboard at all, so you can move your hands over the minimum necessary distance.

Embodiment FIG. 1 is a plan view showing the appearance of one embodiment of the coordinate input device of the present invention, viewed from directly above. As shown in Fig. 1, there is a "coordinate movement" key on the keyboard 1 for inputting character data, etc., in addition to keys 2 for inputting characters etc.
A key 3 called "Coordinate Input" and a key 4 called "Coordinate Input" are installed. These two keys and other keys for generally inputting character data, etc., are connected to a switch, as shown in the block diagram of its internal configuration in Figure 2, and when these keys are pressed, Accordingly, the corresponding switches 6 are turned on and off. This on/off state is expressed as a potential difference from the same block diagram, and each microcomputer-manual port displays oV information if it is on, and if it is off, The information in 6■ is input. microcomputer
7 receives this information, and as shown in the flowchart in Figure 3, if only the key representing a normal character is pressed, it is assumed that a code representing that character has been input. If the key indicating "coordinate movement" is also pressed at the same time, the input of the data corresponding to that character is canceled and instead, the position of that key on the entire keyboard is determined. , and move the coordinates of a certain point to be input accordingly.

In other words, if the pressed key is at the bottom right of the keyboard, the coordinates of the point on the display screen will also move toward the bottom right, the X coordinate will increase, the Y coordinate will also increase, and if the key is pressed If the key is at the top left of the keyboard, the coordinates of the point on the display screen will also be moved to the top left, the X coordinate will decrease, and the Y coordinate will also decrease.

When the microcomputer determines the movement of the coordinates in this way, it places a mark 11 called a cursor as shown in FIG. 4 at the position on the display screen 1o corresponding to the coordinates.
Display. With this configuration, the operator is on the keyboard. If you press a key normally used to input characters while holding down the "coordinate movement" key, the key for inputting characters etc. will move to that position depending on where it is on the keyboard. The cursor moves in the corresponding direction.

The operator looks at the position of the cursor, and when it reaches the position desired by the operator, presses the same "coordinate input" key on the keyboard. Then, the coordinates of the point where the current cursor is located are input by the above-mentioned mechanism.

Effects of the Invention As described above, according to the present invention, the configuration is extremely simple, the operator never takes his hands off the keyboard, and the hand movement distance is extremely small. It is possible to construct a coordinate input device that can be used in the following manner, and the coordinate input device is easy to use and less tiring for the operator, which is extremely useful from a practical point of view.
