[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coordinate input display processing device comprising a pen-type coordinate input device having a function of inputting coordinates in a manner of writing characters with a pen and an information processing device using the coordinate input device.

[0002]

2. Description of the Related Art In recent years, due to the diversification of input devices of information processing devices, pen-type coordinate input devices have become widespread in addition to input devices that use a mouse or tablet in addition to a keyboard. An example of a conventional coordinate input device will be described below with reference to the drawings.

FIG. 7 is a perspective view showing an information processing device 70 in which the mouse 71 is connected to a coordinate input device using the mouse 71. The mouse 71 is connected to the mouse input terminal 74 of the information processing device 70 by the connection cord 72, and the mouse 7
The input switch 73 provided on the upper surface of 1 designates the coordinate points and sets the operation. In the coordinate input device configured as described above, the mouse 71 is placed on a plane on a desk, and the connection cord 72 is connected to the information processing device 70.
Connected to the mouse input terminal 74. When the operation setting for using the mouse 71 is made on the information processing device 70 side, a cursor 76 showing the current position of the coordinate point appears on the display screen 75 of the information processing device 70. In FIG. 7, the state of the display screen 75 when the mouse 71 is connected is shown, and the cursor 76 representing the coordinate point is the position of “+” in the figure. At this time, the spherical object inside the mouse 71 comes into contact with the desk and rolls, and the distance and direction are detected and the connection cord 72
A moving signal is sent to the information processing device 70 through the, and the cursor 76 on the display screen 75 moves. “Hitachi” and “ai” displayed on the display screen 75 are input by the mouse 71, and when the operator moves the mouse 71, a drawing operation is performed, and the locus is displayed on the display screen 75. is there.

A tablet is another coordinate input device for the mouse 71. Various methods have been devised for this tablet, such as pressure-sensitive sheets and
A method of detecting the position by strongly pressing the tablet surface made of a conductive sheet with a pen is used.

A coordinate input device of this type is disclosed in, for example, Japanese Patent Laid-Open Nos. 63-223816 and 63-2.
In addition to a mouse and a tablet, a pen-type coordinate input device is proposed in Japanese Patent No. 23817, Japanese Patent Application Laid-Open No. 63-193219 and Japanese Patent Application Laid-Open No. 1-142819.

[0006]

However, with the above-mentioned structure, in the case of a mouse, it takes time to get used to the operation because a pen having a shape completely different from that of a pen normally used by humans is moved. Even if I got used to the mouse enough, I could not do the same fine drawing operations as when writing with a pen, and I could only point to a large area.

Even when characters and figures are input by drawing operation, it is common to operate by looking at the display screen without looking at the mouse at hand. It was necessary to operate in an environment different from the actual one, such as whether to fill in with a different layout.

On the other hand, there is an information processing device 80 shown in FIG. 8 in which a tablet 81 is built in the device and input with a pen 82, but the size of the tablet 81 is limited because it is portable, and for example, an A4 size paper surface. It gives the user a very uncomfortable feeling when inputting as an image of, and from this size, assume the size when inputting characters and the arrangement on the paper for the size of the paper when trying to output. It was very difficult. Further, it is conceivable that the layout state which is imaged on the paper surface is displayed on the screen by the editing after the input without outputting it from the information processing device. However, in that case, it is obvious that the size of the display itself can be reduced or split display can be performed in the editing work, but this is only in the editing work after the input, and these are displayed during the input work. The work could not be done efficiently.

Further, in the case of a tablet, coordinates can be input in the manner of pen operation, but for example, since a tablet plate using a pressure sensitive sheet or an electric shock sheet is required, a space for placing the tablet is required. It was

Further, although the various pen-type coordinate input devices proposed in the above-mentioned publications are convenient for the user, regarding the coordinate points displayed on the display screen, Japanese Patent Application Laid-Open No. 63-63242
In the pen-type coordinate input device disclosed in Japanese Patent Laid-Open No. 223816, Japanese Patent Laid-Open No. 63-223817 and Japanese Patent Laid-Open No. 63-193219, an operator or a user touches the pen tip of the pen-shaped coordinate input device. There is a problem that you cannot move it to the desired position the moment you hit. Further, in the invention described in Japanese Patent Laid-Open No. 1-142819, a tablet is further required to solve this problem.

In view of the above problems of the prior art, it is an object of the present invention to provide a coordinate input display processing apparatus capable of easily inputting fine coordinate such as drawing in a small space like a pen operation. And

[0012]

To achieve the above object, the present invention has means for transmitting position information of a pen tip, and means for detecting contact of the pen tip with an arbitrary surface. A pen-type coordinate input device for transmitting position information of the pen tip by the transmitting means when the tip contacts the arbitrary surface, and receiving the transmitted position information of the pen tip,
An information processing apparatus having means for calculating a trajectory of a pen tip to associate an actual trajectory of the pen tip with a position on a display screen, and means for displaying on the display screen in accordance with an output signal of the association means. The display processing device displays on the display screen a locus from when the pen tip contacts the arbitrary surface to when the pen tip leaves.

In this case, the pen-type coordinate input device includes means for detecting the moving distances of the pen tip in the X and Y directions on the arbitrary surface, and the moving distances detected by the detecting means as the information. Means for transmitting to the processing device side may be further provided. Further, it is preferable that the pen tip is composed of a spherical body rotatable in all directions, and the means for detecting the movement distance in the X direction and the Y direction is composed of an encoder. Further, for example, a pressure detection sensor can be used as a means for detecting that the pen tip has contacted an arbitrary surface. Further, the means for transmitting is composed of a signal transmitting unit and an antenna for oscillating the radio wave output from the signal transmitting unit to the outside, and a clip provided in the main body of the pen-type coordinate input device can be used as the antenna. . Further, it is also possible to provide a means for supplying ink to the pen tip so that ink can be recorded on the arbitrary surface, for example, the paper surface.

The corresponding means in the information processing device receives the position information transmitted from the pen-type coordinate input device via two receiving antennas, and calculates the position of the pen tip by, for example, trigonometry. Specify. Further, the information processing apparatus may further be provided with a unit for recognizing a character or a symbol from the locus associated by the associating unit and converting it into code information. The generated code information can be converted into character and symbol information and displayed as a font on the display screen. These pieces of code information are stored in the storage means, and it is possible to provide them with a word processor function such as editing. At the time of these processes, it is desirable to associate the paper with the input size, and therefore, it is preferable to provide a means for associating the input size of the arbitrary surface with the size of the paper.

According to this structure, the information processing device can receive the information generated from the pen-type coordinate input device and process the information to be input from the pen-type coordinate input device. At this time, since the coordinate input device is a pen type and can transmit the information signal wirelessly, it is possible to easily perform fine coordinate input in a small space and in a manner of writing with a pen.

DETAILED DESCRIPTION OF THE INVENTION A pen-type coordinate input device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a pen-type coordinate input device 1 according to an embodiment of the present invention. In FIG. 1, a pen-type coordinate input device 1 includes a pen tip 2 formed in a spherical shape and freely rotating in all directions, a pressure detector 3 for detecting the pressure at the tip of the pen tip 2, and a detector (not shown). Two directions with different amounts of rotation of the pen tip 2 (X direction, Y direction)
The encoder 4 that detects the rotation amount and converts the detected rotation amount into an electric signal, the pen tip position output unit 5 that outputs information regarding the position of the pen tip, the changeover switch 6 that switches the above information, and the information processing device 13, a signal transmitter 7 for transmitting as a signal to the battery 13, a battery 8 for driving each of the above parts, a clip 9 serving as an antenna for transmitting from the signal transmitter 7, ink is supplied to the pen tip. Ink reservoir 10, pen case 1 that covers the outside
1 and the lid 12 at the upper end of the pen case 11.

On the other hand, in the information processing device 13 to which the pen-type coordinate input device 1 is connected, as shown in a block diagram in FIG. 2, a receiving unit 14, a calculation unit 15, a storage unit 16, an input unit 1
7, an output unit 18, a power supply unit 19, and a display unit 20, and have an appearance as shown in FIGS. 3 and 4. That is, a pair of antennas 1 is provided on both sides of the upper end.
4a and 14b are provided, and the signals received by the antennas 14a and 14b are input to the receiving unit 14 of the information processing device 13. Further, on the upper surface of the information processing device 13, as can be seen from FIG. 3, for example, a display screen 2 including a liquid crystal and a touch panel is displayed.
0a is provided and functions as the display unit 20.

Generally, in the pen-type coordinate input device 1 and the information processing device 13 configured as described above, the pen-type coordinate input device 1
The coordinate position pointed at is taken into the information processing device 13 and the coordinate is input. The acquisition of these coordinates is performed by wireless communication. Hereinafter, the operation will be described.

The basic operation of the pen-type coordinate input device 1 is similar to that of the conventional mouse 17, and it can be considered that the shape thereof is a pen-type. Therefore, for the coordinate position, the rotation of the pen tip 2 is captured by the encoder 4, the locus between the coordinate position and the movement is calculated by the calculation unit 15 of the information processing device 13, and the information input to the display screen 20a of the display unit 20 is calculated. Display correspondingly. On the other hand, when selecting the character string 21 in which the message corresponding to the command on the display screen 20a of the information processing device 13 is displayed, the pen tip 2 of the pen-type coordinate input device 1 is brought into contact with an arbitrary plane, for example, a desk, and While looking at the pointer on the screen of the display device 20a, move the character string 2
When the position is designated by operating the switch 6 in 1, the operation of the designated character string 21 can be executed. Naturally, the character string 2 on the display screen of the display device 20a
It goes without saying that you can also input by pointing on 1.

The pressure detection unit 3 is composed of, for example, a pressure detection sensor, senses the pressure of the pen tip 2, and determines from the contact pressure whether the pen-type information processing device 1 is in contact with the flat surface of the desk or the like. Upon determination, the pen tip position output unit 5 receives the signal from the pressure detection unit 3 and transmits a signal indicating that the pen has come into contact with the flat surface. The transmitted radio wave 22 is received by the two antennas 14a and 14b, taken into the calculation unit 15 via the reception unit 14 of the information processing device 13, and specifies the position of the pen tip 2 on the information processing device 13 side. This makes it possible to specify the position where the writing started with the pen. For this,
The pen tip position output unit 5 is provided at a position as close to the pen tip 2 as possible and two antennas 14a and 14b are provided, and from the signals received by both the antennas 14a and 14b based on the principle of trigonometry, the arithmetic unit 15 The distance and the direction are calculated, and the position of the pen tip 2 is specified.

In the case of a pen, the operation is the same as when a person writes a character, so it is important from which position the character starts to be written, and this is also used to determine whether it is a single character or a character string. The writing position is important information. When the writing start position is known, the X-direction and Y-direction distances detected by the encoder 4 are detected by the encoder 4 as long as the pen tip 2 comes into contact with the clip 9 that functions as an antenna. Based on the received distance information transmitted to the information processing apparatus 13 side, the calculation unit 15 calculates the movement distance and the movement direction, in other words, the locus, and displays a character or a figure similar to the written one on the display unit 20. Display on the display screen. At that time, it is possible to display the trail of the pen tip of the display device 20a only from the pen tip position information from the pen tip position output unit 5, but the characters and figures themselves are the information detected using the encoder. Is more advantageous in consideration of accuracy and cost. Therefore, in this embodiment, the writing start point of the character, for example, the starting point of the horizontal bar or the vertical bar is the pressure detection unit 3.
Is detected, the point is output by the pen tip position output unit 5, and the state (coordinates) of the line drawn after writing is detected from the rotation of the pen tip 2 via the encoder 4. The encoder 4 includes pulse counters 4a and 4b in the X and Y directions for counting the rotation amounts of the sphere of the pen tip 2 in the X and Y directions, respectively, and inputs the counted number of pulses to the signal transmitter 7. , Is output from the signal transmitting unit 7 as described above.

Here, a case will be described in which what is actually written on paper is also taken into the information processing device 13 to input characters.

In general, information processing work is often performed on some kind of printed matter, and it is common to predetermine the paper size and perform information processing. Therefore, when inputting, if the size of the paper and the size of the display screen are not taken into consideration, the input characters or figures and the characters or figures displayed on the display screen will not correspond one to one. . Therefore, when inputting the size of this paper into the information processing device 13, as shown in FIG. 4, first, the pen coordinate input 23 is performed from the character string 21.
The operation is switched to, and then the size of the paper surface is initialized. This is an arbitrary corner portion A of the paper surface 24, as shown in FIG.
By picking up the points B and C in this order, a signal is generated from the pressure detection unit 3 that detects the pressure of the pen tip 2, and the positional relationship between the paper surface 24 and the information processing device 13 is determined by the pen-type coordinate input device 1. It is sent as an information signal and its position and size can be specified on the information processing device 13 side.
This makes it possible to determine at which position on the paper surface 24 of what size the operator (user) is, and at what size the character or graphic is to be input.

A specific processing procedure at this time is shown in FIG.
This will be described with reference to the flowchart of FIG.

That is, first, in step 601, the position of the first point (point A) is input. Next, the position of the second point (point B) and the position of the third point (point C) are input in the counterclockwise direction (steps 602 and 603). At the second point, the width of the paper is the second
The length of the paper can be specified by the third dot and the third dot. If the size (size) of the paper can be specified in this way, step 6
In 04 and step 605, it is confirmed whether the size is between the maximum size and the minimum size, and if it is not within the range, the size is set again (NO in step 604 or 605). If it fits within the size,
In step 606, the paper size is changed to, for example, A4, A3, B.
5, B4 or any other size (free size) is specified, the position corresponding to the position of the paper surface 24 input by the pen-type coordinate input device 1 is specified on the display screen 20a, and the position is input from that position. Display the displayed characters and figures. At this time, characters and figures are simultaneously written on the paper by the ink supplied from the ink reservoir 10 (step 607). When the ink is not used and is simply used as a pointing device, an ink supply switch (not shown) is turned off. Therefore, when the pen-shaped coordinate input device 1 is actually used for handwriting with ink on the paper surface 24, the information processing device 13 side converts and edits characters, and at the same time, characters and figures are written. The paper surface (paper) 24 can be left as the original at that time.

The information processing device 13 is configured to transfer the characters and figures input by the pen-type coordinate input device 1 to the display screen as they are, as described above, but in addition to this, the calculation unit is also provided. Since the character recognition function 15 is provided, the input character can be read and converted into Kanji, or converted into a desired character and displayed, or coded. That is, in FIGS. 3 and 5, the operator inputs “ai” on the paper surface 24 with the pen-type coordinate input device 1,
After that, by selecting the "convert" section 25 of the character string 21, the hiragana "ai" input to the information processing device 13 is converted into "love" desired by the operator and displayed. In this embodiment, the operator continues to use the Chinese character "Hitachi."
Is being input, and the information signal 22 is wirelessly transmitted to the information processing device 13 while the pen tip 2 is in contact with the paper surface 24.

Therefore, on the display screen, the input state is displayed as it is, the information after Kana-Kanji conversion is displayed, the entire layout is displayed, and the partial enlargement / reduction is performed.
Alternatively, it can be displayed at the same size. Although not shown in the figure, the item "mode selection" is provided in the character string 21, and the desired mode can be selected from this item. Note that, as shown in FIG. 3, the switching of the paper surface can be executed at appropriate times. This switching is performed by operating the above-described change-over switch 6, and for example, it is easy to input the first page, the second page, and the input order of a page 19 on a front page, a rear page, and a document extending over a plurality of pages. Can be switched. Also, it is possible to change the size of the display screen by operating the changeover switch 6, for example,
This can be easily set by setting the environment on the information processing device 13 side. Therefore, in step 608, if the page is not switched, the processing up to this point is ended, and if the page is switched, the step 6 is executed.
At 09, it is confirmed whether the paper size or the paper position is changed, and the processing from step 601 is executed again.

The changeover switch 6 is also used for inputting the pen tip position and paper size as described above.
For these inputs, one operation (click once) of the changeover switch 6 inputs the pen tip position, two operations input the paper size, and 3
It is set so that the turning operation (clicking three times) is performed by allocating the function depending on the number of times of operations such as page switching. It is needless to say that these settings can be changed as appropriate, and a switch having the above-described function may be separately provided.

As described above, according to this embodiment, the coordinate points can be designated in a small space, and the space on the paper 2 can be specified.
Even when drawing a line on 4, it is possible to operate in exactly the same way as when writing a character with a pen, so fine input is possible and the same line as the trajectory of the pen tip 2 can be drawn on the screen. . As a result, the same picture can be input to the information processing apparatus 13 and displayed on the display screen 20a by simply tracing the picture drawn on the actual paper.

Further, in this embodiment, the clip 9 of the pen-type coordinate input device 1 is made to function as an antenna,
For example, even if it is put in a pocket or the like, it can be stopped with a clip, and it has excellent portability.

[0032]

As described above, according to the present invention, the pen tip has the means for transmitting the position information of the pen tip and the means for detecting that the pen tip touches an arbitrary surface, and the pen tip has the above-mentioned arbitrary point. The pen-shaped coordinate input device for transmitting the position information of the pen tip by the transmitting means when the surface is touched, and the position information of the transmitted pen tip is received, the trajectory of the pen tip is calculated, and the pen tip trajectory is calculated. An information processing apparatus comprising: a unit that associates an actual locus with a position on the display screen; and a unit that displays on the display screen according to the output signal of the associating unit. Since the locus from when the pen tip comes into contact with the arbitrary surface to when it separates is displayed on the display screen, fine coordinate input such as drawing can be easily performed with the same operation as the pen operation in a small space.

Since the input range can be freely set according to the medium such as paper, the input range is restricted from the size of the conventional tablet, and the drawing operation can be performed freely. Therefore, coupled with the fact that a connecting means such as a cord for connecting the input side and the information processing side is unnecessary, the operability can be remarkably improved.
