Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pen-type coordinate input device having a function of inputting coordinates in the same way as writing with a pen.

2. Description of the Related Art In recent years, with the diversification of computer input devices, coordinate input devices such as mice and tablets have become popular as auxiliary input devices in addition to keyboards.

An example of the conventional coordinate input device mentioned above will be described below with reference to the drawings. FIG. 2 shows an external view of a conventional coordinate input device called a mouse. In FIG. 2, 21 is a connection cord connected to a mouse input terminal of a computer, 22 is a mouse body, and 23 is an input inch for specifying coordinate points and setting an operation mode. Further, FIG. 3 shows an external view of a conventional coordinate input device called tab left. In FIG. 3, 31 is a connection cord connected to the tablet input terminal of the computer;
32 is an input pen; 33 is an input switch at the tip of the input pen for specifying a coordinate point and setting an operation mode; 34
is a tab left board for setting coordinates that corresponds to the computer display screen.

The operation of the coordinate input device configured as described above will be explained below.

First, in the case of the mouse shown in FIG. 2, when using the mouse body 22, place it on a flat surface on a desk and connect the connection cord 21 to the mouse input terminal of the computer.

When the mouse mode is set on the computer side, a cursor indicating the current coordinate point position appears on the screen of the computer's display device. FIG. 4 shows a state diagram of the display screen when a coordinate input device is connected in the conventional example, and the cursor representing the coordinate point is at the "+" position in the diagram. For example, in Figure 4, when using the mouse to select the character string "list display" that corresponds to a certain command on the screen, move the mouse body 22 on the desk to move the cursor in the direction of the character string. move it. At this time, a spherical object inside the mouse body 22 contacts the desk top and rolls, detects the distance and direction, and sends a movement signal to the computer through the connection cord 21, causing the cursor on the screen to move. And the cursor is the desired character string "List display"
If the input switch 23 is pressed when the character string is directly above the character string, the target character string is selected, a command to "display list" is input to the computer, and a list of files is displayed on the screen. You can also set the on-screen "drawing" mode to draw on the screen as you move the mouse.

Next, in the case of the tablet shown in FIG. 3, when using the tablet Ifi, 34 is placed on the desk and the connection cord 31 is connected to the tablet input terminal of the computer.

The input pen 32 is used on the tablet board 34, but unlike the case of the mouse described above, the display screen of the computer corresponds to the tablet board 34, so in the case of the state diagram of FIG. 4, the character string " When selecting "List display", directly specify the coordinate point on the tablet board 34 corresponding to the "List display" position on the screen with the input pen 32, and then move the input switch 33 at the tip of the input pen to the tablet board 34. The desired character string is selected by pressing lightly on the top, and "List display" is displayed.
This command is entered into the computer and a list of files is displayed on the screen. Also, as with the mouse, if you set the "draw" mode, you can use the input pen 32 on the tablet board 34 to draw lines on the screen in the same way as writing with a pen. Some methods have been devised, such as a method in which a magnetic delay line is embedded in the tablet surface, a pulse is run on the magnetic delay line, and the pulse position is detected with an input pen with a pulse detection coil on the tip, and a method using pressure-sensitive sheets or conductive sheets. This device was realized using a special method that detects the position by pressing firmly with a pen on the left side of the tablet made of.

Problems to be Solved by the Invention However, with the above configuration, not only does it take time to get used to operating the mouse, as it moves an object with a shape completely different from the pen that humans are accustomed to using. Even if you got used to using a mouse, you would not be able to perform detailed drawing operations similar to when writing with a pen, and the problem would be that you would only be able to point over large areas. In addition, in the case of a tablet left, coordinates can be entered using a pen, but it requires a special tablet board that is compatible with the display screen created using the magnetic delay line, pressure-sensitive sheet, and conductive sheet mentioned above. The problem was that it required a space large enough to accommodate.

Furthermore, conventional input devices such as a mouse or tablet left must be used in conjunction with the main computer. In other words, there was a problem in that it was not possible to input coordinates at a separate location away from the main computer.

In view of the above-mentioned problems, the present invention provides a pen-type coordinate input device that allows detailed coordinate input such as drawing as easily as pen operation in a small space, and that can be used independently of the main computer. be.

Means for Solving the Problems In order to solve the above-mentioned problems, the pen-shaped coordinate input device of the present invention has a pen-shaped coordinate input device that allows the user to move while the tip of the pen-shaped holder is in contact with a plane made up of unspecified objects. , a moving distance input section for inputting information regarding the distance traveled by the tip, a moving direction input section for inputting information regarding the moving direction, a CPU, and information input from the moving distance input section and the moving direction input section. It is equipped with a storage section that stores information, and a power source.

According to the present invention, with the above-described configuration, by making the coordinate input device pen-shaped, it is possible to input detailed coordinates easily in a small space, just like writing with a pen, and without the need for a tablet board. By having processing and data storage functions, coordinate input can be performed independently of the main computer.

Example Below, regarding a pen-type coordinate input device according to an example of the present invention,
This will be explained with reference to the drawings. FIG. 1 shows a configuration diagram of a pen-type coordinate input device according to an embodiment of the present invention. In FIG. 1, reference numeral 11 indicates a moving distance input section for inputting information regarding the distance traveled by the tip of the pen-shaped holder, reference numeral 2 indicates a moving direction input section for inputting information regarding the moving direction of the tip, and 13 indicates a CPU. , 14 is a storage section, 15
is the power supply.

Regarding the pen type coordinate input device configured as above,
The operation will be explained below using FIG.

The basic operation is the same as that of a conventional mouse, and the shape can be thought of as a pen-shaped one similar to that of a tablet. When selecting a character string that corresponds to a certain command on the screen, move the tip of the pen-shaped coordinate input device toward the character string while touching a plane made of unspecified objects. Information regarding the distance and information regarding the direction are input to the moving direction input section 11 and the moving direction input section 12, respectively. Although various specific configurations can be considered for 11 and 12, they are designed to independently detect the contact movement distance in the X and Y directions, similar to a conventional mouse, and a small ball is attached to the tip of the pen to make contact with a flat object. There is a method that detects rolling when moving, or a small sheet for position detection is placed on the desk, the tip of the pen is moved on the sheet, and the tip of the pen is read optically to determine the distance and direction of movement. There is a method to detect it. The distance and direction data detected by the moving distance input section 11 and the moving direction input section 12 are directly or C
After processing by the PU13, it may be sent to the main computer by a connection cord or wirelessly, or the CPU1
The data stored in the storage unit 14 may be stored in the storage unit 14 directly or after processing according to 3. The data stored in the storage unit 14 may be in the form of coordinate data, for example, or may be the result of character recognition if the input target is a character. .

As described above, according to this embodiment, there is a movement distance input section for inputting information regarding the distance traveled by the tip of the pen-shaped holder, and a movement direction input section for inputting the emotion I regarding the direction of movement. By providing a CPU, a storage unit for storing information inputted from the moving distance input unit and the moving direction input unit, and a power supply, it is possible to specify coordinate points in a small space, and also to display information on the screen. Even when drawing a line, detailed input is possible in exactly the same way as writing with a pen, and the same line as the tip moves can be drawn on the screen, so for example, it can be drawn on actual paper. Just by tracing the picture, you can create the same picture on the screen.

Additionally, since it has data processing and data storage functions, it is possible to input coordinates independently from the main computer. For example, let's consider a case where the pen-type coordinate input device of the present invention is used as a normal pen to create a document by hand on a piece of paper while leaving the main computer.0 At the same time, the pen-type coordinate input device of the present invention is used to create a document on a piece of paper. Coordinate information indicating the movement of the pen or data as a result of character recognition using that information are stored. The input data stored in the pen-type coordinate input device of the present invention in this manner can be expanded onto the main computer by connecting to the main computer and communicating with the main computer at any time after writing the text.

That is, word processing can be performed at a location away from the main computer (main word processor).

Effects of the Invention As described above, the present invention provides a method for manually inputting information regarding the distance traveled by the tip of a pen-shaped holder when the tip moves while being in contact with a plane composed of an unspecified object. The pen can With just a small amount of space to move around, you can easily input coordinates and draw lines in the same way that we used to draw characters with a pen, and it is also possible to input coordinates without leaving the main computer. .

All humans have been accustomed to using a pen since childhood, and it is a coordinate input device that is much easier to use than a mouse.It is also extremely easy to use, as it does not require a large tablet board compared to conventional tablets. It is possible to achieve the desired effect.
