In order to achieve this object, the input / output device according to claim 1 is a pen shape that can be held and operated by hand, and outputs handwritten character data by an input unit. Output by department. Prior to the output by the output unit, when the user hand-writes the predetermined reference character data with the input unit, the extraction unit extracts the characteristic information of the character of the user based on the handwriting at the time of the input. Then, the character font creating means creates an output character font based on the characteristic information of the characters extracted by the extracting means, and the output section creates the output character font created by the character font creating means. Based on the above, each character data input by the input unit is output.

In the input / output device according to the second aspect of the present invention, the character font of the standard typeface is stored in the storage unit in advance, and the character font creating means is the character font of the standard typeface corresponding to the character data to be output. Is called from the storage unit, and a character font for output is created by performing a predetermined calculation process on the character font of the standard typeface.

Further, in the input / output device according to the third aspect, when the character font creating means creates a character font for output, the specifying means specifies at what ratio the feature information is adopted. be able to.

Further, since the input / output device according to the fourth aspect uses "naga" as the reference character data, the feature of the handwriting of the user can be extracted by inputting one character.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration of the input / output device of this embodiment, and FIG. 2 shows a block portion representing a control system. As shown in FIG. 1, the input / output device 10 of the present embodiment
Is a pen shape that can be held and operated by hand, has a two-dimensional input unit 12 at its tip, and has an output unit 16 having a moving distance measuring unit 14, a control board 18, and its control board 18. A power supply 20 for supplying electric power to the two-dimensional input unit 12 and the output unit 16 is provided inside. Further, on the side surface of the input / output device 10, there are provided a mode changeover switch 24, which is operated at the time of mode changeover described later, and an input completed button 25.

The control board 18 is a CP for controlling the entire equipment.
U18a, ROM18b for storing various programs and standard typeface fonts, and R for temporarily storing the contents input from the two-dimensional input unit 12, each calculation result, and the like.
It is composed of AM18c. The two-dimensional input unit 12 has the same structure as a mouse, and includes a ball 12a and a rotary encoder 12b. Then, when the user inputs a desired character using the input / output device 10 in the same manner as when writing a character on a paper or the like using a normal ballpoint pen or the like, the ball 12a is accompanied by the operation. Rotates, and the rotary encoder 12b measures the rotation of the ball 12a, that is, the two-dimensional movement as the amount of movement in each axial direction of the X and Y axes. Also,
The moving distance measuring unit 14 is composed of a set of rotary encoders, an ink jet system is used for the output unit 16, and the ink ejection ports arranged in a line are formed on the rear end surface of the main body 10. It is exposed to the opening 10e. A rechargeable battery or the like can be preferably used as the power source 20.

The CPU 18a constitutes the extracting means and the character font creating means of the present invention, and the ROM 1
8b constitutes the storage means of the present invention.

Next, the operation of the input / output device 10 configured as described above will be described. FIG. 3 is a flow chart showing the procedure of handwriting registration using the reference character, and FIG. 4 is a flow chart showing the procedure of inputting and outputting a sentence after handwriting registration.

First, the handwriting registration process will be described.
Here, the reference character is a specific character that is predetermined for extracting the characteristics of the handwritten character of the user, and in this embodiment, the character "Naga" is used as the reference character.

When the handwriting registration process is performed, the mode changeover switch 24 is previously pressed to be turned on. Then, the user holds the input / output device 10
While the ball 12a at the tip of the dimension input unit 12 is hit against a paper or the like, the character "naga" is input (S1). When inputting a character, the ball 12a separates from the paper each time between strokes (for example, between consecutive strokes such as the first stroke and the second stroke of the constituent elements of the character), and the "ten "," Information about the length and angle of the "splash" is input from the ball 12a to the rotary encoder 12b. The rotary encoder 12b moves the ball 12a in two axial directions (X,
It is disassembled in the Y direction) and sent to the CPU 18a of the control board 18 as a movement amount in each axial direction. Then, C of the control board 18
In PU18a, "ten" which is the basic element of the typeface,
The characteristic information of the handwritten character of the user regarding the angle, length, etc. of the “splash” is extracted (S2). The extracted characteristic information is stored in a predetermined area in the RAM 18c. The process of S2 functions as the extraction means of the present invention.

In this embodiment, "naga" is used as the reference character, but "ten",
Since it contains all the basic elements of the typeface such as "brush",
It is possible to reliably extract the characteristic information of the handwritten character of the user with simple characters.

Next, with the handwriting registration process completed,
The process of inputting and outputting text will be described.

When inputting and outputting a sentence, the mode selector switch 224 is turned off in advance. Then, the user first of all, the two-dimensional input unit 12
Input an arbitrary sentence by (S10). The input operation is the same as the case of registering a handwriting, and the input completed button 25 is pressed every time the input of one character is completed. The element of each image of each character of the input character string is input from the ball 12a to the rotary encoder 12b. The rotary encoder 12b decomposes the movement of the ball 12a into two axial directions and sends it to the CPU 18a of the control board 18 as the amount of movement in each axial direction. In the CPU 18a of the control board 18, the rotary encoder 12b
Based on the information of each image sent from, the input character recognition process is performed (S11). A well-known method is used for this character recognition processing, and a detailed description thereof will be omitted. The character string recognized in S11 is converted into a character code and stored in the RAM 18c in the order of input.

Next, when the text stored in the RAM 18c is printed out, a standard typeface font provided corresponding to each character code is called and based on the characteristic information extracted using the reference character. It is corrected and expanded as a print output font in the print buffer (S1).
2). The process of S12 functions as the character font creating means of the present invention.

When the standard typeface font is corrected by the extracted characteristic information, a predetermined arithmetic processing is performed using a predetermined correction value c for the length and angle of each element constituting the standard typeface font. This makes it possible to create a printout font that reflects the handwriting of the user. For example, when the length and the angle of the splash of one component of the character in the standard typeface font are a and the length and the angle of the splash of the component corresponding to the component a in the extracted feature information are b, A print output font can be obtained by setting the output value to a + (b−a) × c.

With respect to the modified value c, if c << 1, it is possible to generate a printout font close to a standard typeface font, and if c≈1, it is possible to generate a printout font close to a user's handwritten character. Here, in the characteristic information, since the user writes the reference character large or small as a whole, the component b
The length is calculated based on the overall balance of the written characters. Therefore, it is possible to provide a switch (not shown) on the side of the input / output device 10 for designating how close to the handwritten characters of the user the print output is made. When one stage is designated, the correction value c = 1, when two stages are designated, the correction value c = 0.75, when three stages are designated, the correction value c = 0.5, four stages are designated. Correction value c =
A method of setting such as 0.25 can be considered. This designation switch constitutes the designation means of the present invention.

In S13, when the font for print output developed in the print buffer is printed out,
When the rear end of the input / output device 10 is pressed against a medium such as paper, the ink ejection port of the output part 16 is provided in the movement distance measuring part 14 while keeping a predetermined distance from the medium. The roller 14a and the rollers 22a and 22b are supported at three points. When the input / output device 10 is moved in the movable direction of the rollers 22a and 22b along the printing direction of the medium while being pressed against the medium, the movement distance measuring unit 1
At 4, the moving distance is detected and sent to the CPU 18a of the control board 18. CPU 18a of control board 18
Then, the print output pattern is sequentially read from the print buffer according to the moving distance, and the inkjet head of the output unit 16 is controlled to print the input sentence.

As described above, according to the present embodiment, it is possible to easily perform the print output reflecting the user's handwriting with a small pen-shaped device without using a large-scale keyboard or a printing device as in the prior art. Therefore, the usability is improved.

Further, since the feature extraction of the handwritten character of the user is performed only by the operation of inputting the normal handwritten character without using an image reader or the like, the print output reflecting the handwriting of the user can be very easily performed. Obtainable.

Furthermore, when creating a print output font, it is possible to specify to what extent the user's handwriting is reflected, so it is possible to easily create a print output font according to circumstances and use it properly. You can

Further, since the output section 16 uses the ink jet system, high-definition print output can be performed.

The present invention is not limited to the above embodiment, but various modifications can be added.
For example, the font may be modified to be italic or emphasized according to a certain rule when the print output font is generated.
