Abstract

PURPOSE:To enable recognition of characters immediately after writing characters, etc., by installing an optical fiber around the tip of a pen, by analyzing signals from the fiber and by reading a direction of pen's movement. CONSTITUTION:A tip of a pen 1 is constituted in the same manner as writing tools as a pencil or ball point pen. Plural optical fibers 3 are fixed around the pen's tip. The fiber 3 for example, eight of them are fixed around the pen tip in all directions. The lines comprising characters, symbols, and patterns depicted on a sheet of paper by the pen 1 are detected if only a change in the quantity of the light coming into the fiber 3 is detected. Only while the pen tip is pressed against the paper, the pen reads a light line input from the fiber 3. A signal analyzing device 8 analyzes and records writing patterns from the change in input light quantity. A character recognizer 9 compares patterns such as characters registered in a memory 10 with patterns inputted from the device 9 to recognize characters and so on.

Description

[Detailed description of the invention] "Technical Field J The present invention relates to a character/figure recognition device.

[Back BH Technology 1 Conventional character recognition devices read characters that have already been written as dot patterns, and perform pattern recognition. This method recognized characters as the result of old-fashioned writing, and ignored the information contained in the writing process. Therefore, only characters of a specific size and shape5)
“The problem was that it was difficult to fully understand the process, and there were many human errors.

[Invention 1] Furthermore, the present invention has been provided in view of the above points, and includes:!
：Provides a character/figure recognition device that recognizes characters, symbols, figures, etc. immediately after they are written by detecting and analyzing the direction of drawn lines. It is something to do.

[Disclosure of the invention 1 Embodiments of the present invention will be described below with reference to the drawings.

In the figure, numeral 1 is a pen, and the pen tip 2 at the tip of a holder 4 constituting an outer shell has a structure similar to that of a writing instrument such as a pencil or a ballpoint pen, and is used to write characters on paper. 6 is a clip. In addition, am optical fibers 3 are attached around the pen tip 2 as shown in figure f52.
In this example, Hikari 7 Aivar! (21 wires are used, but 11 wires are sufficient for the shell. 7 is the lead wire.

The Y fiber 3 has at+1 fibers arranged diagonally in the upper and lower right of the pen tip 2, and the letters, memories, figures, etc. written by Ben 1 on the paper 1. The constituent lines are connected to the fiber: (by detecting changes in the amount of light entering the fiber) After one symbol is written, press it to
) This is to notify the H'ff analyzer 8 that the first character, first letter, etc. has been successfully completed. The first 2 is on the paper.'' So Q7y Ibar 3 only while being pressed by Yu
Reads the ray input from. Fig. 48 shows the overall block diagram, and the No. 48 analyzer 8 converts the change pattern of the amount of human power light to the optical fiber 3 by the line drawn on the paper into an electrical No. 45, analyzes and records the handwriting pattern. Do this. 9
is a character recognition control device that compares the handwriting patterns of characters, symbols, figures, etc. registered in advance in the memory 0 with handwriting patterns manually input from the signal analysis device 8,
(1) The written characters, symbols, and figures are recognized, stored, and displayed on the display device 11.

Hereinafter, the process of character recognition 1 will be explained using the character "1." as an example. First, as shown in FIG. For convenience, the numbers are 31 to 3.Next, as shown in Fig. 4 (II), when Ben 1 is lowered from top to bottom and the vertical line is drawn by g, the amount of light directed only to the fiber 31 is This change indicates that the signal corresponding to the output fiber 31 becomes high level (on) as shown in Fig. 5(a), indicating that the written line is being detected. , by moving Ben 1 from left to right as shown in Figure 4(c), the amount of light to the optical fiber 37 installed on the left side of Ben 1 changes.At this time, Ben 1 moves to the left. At the same time, the optical fiber: ) 6 undergoes a slight change in the scene due to the lower part of Rm, and outputs a high level A1: like No. 51;
No. 411, which corresponds to Ai-;), is at a high level as shown in FIG. After the character "II," has been written, the scribe presses the button switch 5, which notifies the signal analyzer 8t that the character "J:" has been written. In addition, since the other optical fibers 32 to 36 are not subject to changes in light intensity, the signals to be trimmed are PIS 5 (1)) to
It is in a low level (off) state as shown in (V).Next, the signal analyzer 8 reads the change in the amount of light inputted from the optical fiber 3, and converts it into electric power, ?υ. Analyze and record how the light intensity of each optical fiber changes over time.The character recognition control device 9 stores in advance the IC amount change pattern from the signal analysis device 5 in the memory 10. The characters, symbols, or figures that have the closest pattern are compared with the existing light intensity change pattern, and the characters are displayed on the display device (CRT) 1.
Table 74' is shown in Table 1. In this case, rLJ is displayed. If the human-written characters cannot be recognized, a reading error will be displayed and you will have to input the characters manually.

Able to recognize letters, symbols, figures, etc. regardless of size or shape, and be able to recognize letters, symbols, etc. immediately after reading letters, notes, and figures. This has the effect of making input and recognition faster and easier than before. In addition, humans can recognize the sentences 'f:', symbols, etc. by registering each individual's characters, symbols, etc. in advance as a sign f pattern, since characters, symbols, etc. have their own characteristics for each individual. It is something that increases efficiency.
