An example in which the present invention is implemented in a written character recognition device will be described below with reference to the drawings. FIG. 1 shows an example in which a ballpoint pen is used as the writing instrument. In FIG. 1, reference numeral 1 denotes a writing instrument body, within which a ballpoint pen lead 2 is swingably supported by a support member 3. Further, an electronic circuit is provided in the main body 1, and the ink storage portion of the core 2 is made of an insulating member, and one tip is configured to have a small diameter. It is adapted to be led out to the outside through a through hole 4 formed at the tip. That is, a knock button 5 is provided on the head of the main body 1, and by operating the knock button 5, the tip of the lead 2 is led out through the through hole 4 to the outside of the main body, or is housed inside the main body. It looks like this. Further, on the outer peripheral surface of the main body 1, a display section 6 is provided along the longitudinal direction, and a clip 7 is also provided. The display section 6 is composed of, for example, a dot display electrode, and is capable of displaying alphabetic characters, kana characters, numbers, and the like. Further, on the inner wall of the main body 1, three pressure sensitive elements 8a to 8, for example, pressure sensitive rubbers 8a to 8 whose resistance value changes depending on the pressure, are arranged so as to be in sliding contact with the small diameter portion 2a of the core 2.
c and one elastic member are provided concentrically with a predetermined spacing therebetween. The resistance value of the pressure sensitive rubbers 8a to 8c changes depending on the pressure applied during writing, but the resistance value can be controlled by the pressure sensitive rubbers 8a to 8c.

Next, the structure of the electronic circuit provided in the main body 1 will be explained with reference to FIG. In the figure, 1 is a switch that is linked to the knock button 5 in FIG. 1 and turns the power supply circuit 12 on and off. The power supply voltage output from this power supply circuit 12 is supplied to each circuit described later. still,
Reference numeral 13 denotes a detection circuit that detects a change in the resistance value of the pressure sensitive rubbers 8a to 8C and outputs a signal of Pa1" or Pa0#, and the detection signals T1 to T3 are sent to the CP via the input port 14.
The signal is sent to U J s, and is also input to the irradiation detection circuit 16. This signal detection circuit 16 detects the rising and falling edges of the output signal Tl-'rs of the detection circuit 13, and its output signal is sent to an AND circuit 18 which is dart-controlled by an interrupt flip-flop 17. The signal is input to the interrupt input terminal INT1 of the CPU 15 via the CPU 15. The flip-flop 17 is set or reset by a signal from the CPU 15. Further, the output signals T1 to T3 of the detection circuit 13 are inputted to a clear terminal of a timer 20 via an OR circuit 19. This timer 20 is only for detecting a break between input characters, and starts operating in response to a set output from a timer flip-flop 21, and counts clock pulses φ. The timer 20 outputs a carry signal when it counts a certain number of clock pulses φ, and inputs it to the interrupt input terminal INT 2 of the CPU 15 .

The timer flip-flop 21 is controlled by the CPU J 5, and its Q side output is the timer 2
0 as an operation command and is also input to CPU J5. This CPU Is is an arithmetic control unit ACU

Z, address resolver al, a2, 7 lags F, ~F3. The CPU 25 is connected to the mother turn memory 222 and a dictionary memory 23 for translating between Japanese and English. The above Tsukuturn memory 22
Character data such as input characters alpha pe, g, katakana, etc. and their standard patterns are written in . In this case, the standard pattern is, for example, r123jJ.

If there are consecutive numbers like r54321J, replace the multiple numbers in between with one character "6",
"1234" is r 164J.

If it is r54321J, it is compressed like r561j. Further, the dictionary memory 23 has written therein Japanese and English word data, corresponding mutual addresses, and address data indicating addresses of tb translation words. And the above-mentioned 4-turn memory 22. The contents of the dictionary memory 23 are read out to the CPU 15 according to the address data set in the address register &1+'2.

The display data output from the CPU J 5 is then sent to the character generator 25 and converted to dot/f.
Converted to turn data. The output of the character generator 25 is inputted to the upper bit side of the shift register 27 via the dart circuit 26, and is also inputted to the lower bit side of the shift register 27 via the dart circuit 28. The shift register 27 has a capacity to store one character's worth of main turn data, and the output from the lower bit side is sent to the upper bit side of the shift register 29 via the dart circuit 28.

6. OR circuit 30. The signal is input to the lower bit side of the shift register 29 via the dart circuit 31. This shift register 29 has a capacity to store one line of character numbers and turns, and the stored data is sent to the display section 6 and displayed.

The dart switching control of the gate circuits 26, 28, 31 and the shift control of the shift registers 27, 29 are as follows:
This is done by the control circuit 32. A control command is sent to the control circuit 32 from the CPU J 5, and a control command is sent to the control circuit 32 via the microswitch MS.
n signals are input. Furthermore, the connection end of the microswitch 33 in the control circuit 32 is grounded via a resistor 33. Further, a buzzer 34 is connected to the CPU 15 to notify, for example, of errors, completion of recognition, etc.

Next, the operation of the above embodiment will be explained. When inputting characters, the knock of the writing instrument shown in FIG. 1 operates the tongue 5 to lead the tip of the lead 2 to the outside (through the through hole 4 of the main body 1). At this time, the switch 11 of the electronic circuit shown in FIG. 4 provided in the main body 1 is turned on, and the operating voltage is outputted to the power supply circuit 12 and other circuits. When a desired character is input into the writing instrument with the clip 7 facing forward, pressure is applied to the pressure-sensitive rubbers 8a to 8C in accordance with the writing operation, and this causes pressure-sensitive rubbers 8a to 8C to be input. The resistance value of 8C changes and character data is input. That is, in FIG. 4, when the resistance values of the pressure sensitive rubbers 8a to 8C change, the detection circuit 13 detects this state and outputs detection signals T1 to T3. The output signals T1 to T3 of this detection circuit 13 are
It is sent to CPU J s via input port 14 and written to register X.

In this case, the first digit Xl of the register X is written with a signal T1, the second digit X+Km number T2, and the third digit x3 is written with a signal T3. The output signals T□ to T3 of the detection circuit 13 are sent to the pulse detection circuit 16, where rising and falling edges are detected, respectively, and the pulse detection signals are sent to the CPU 15 via the AND circuit 18. It is input to the interrupt input terminal INT1. The AND circuit 18 is normally kept in an open state by receiving the "'1" signal from the interrupt flip-flop 17. The output of the detection circuit 13 is still sent to the timer 20 as a clear signal via the OR circuit 19. Therefore, when the °'1# signal is input to the interrupt input terminal INTJ, the CPU 15
Interrupt input processing is performed according to the flowchart shown in the figure, and characters and patterns are created in response to character input.

That is, as shown in step A1 of FIG. 5, the CPU I s first performs an interrupt flip-flop f 2 .

is reset, the dart of the AND circuit 18 is closed, and subsequent interrupt input is prohibited. Next, as shown in step A2, it is determined whether or not the timer Frizzofrodde 20 has been reset, and if it has been reset, Stella: 17''A
Step 3 sets the timer flip-flop 2o, and then proceeds to step A4. In addition, if it is determined in step A2 that timer flip 70 7'' 2o is set, the process directly proceeds to Stella 7° A4. In Step A4, the contents of register Y are incremented by one digit,
Next, in step A5, the interrupt signal is delayed by a minute time to generate a data read command, and the input data held in the input port 14 is transferred to the register X. In this case, the signal T1 from the detection circuit 13 is set to the first digit of the register X, the signal T2 is set to the second digit, and the j signal T3 is set to the third digit
Write K. After that, the process proceeds to step A7, where it is determined whether the contents of the two digits of register X, Xl, are (0,0), and
), the process advances to step A8. In step A8, Xi of register X, 2-digit content JE (1, 0),
(1,1), [0,1) '/J), and if it is [1.0], write "1" to the first digit of register Y in step 'A9, and , 1], put "2" into register Y at Stella 7°AIO,
(In the case of o, B, it is determined in step All whether the contents of the X2 and 3 digits of the register X are [1, 0) or [1, 1].

If the result of this judgment is [1, 0,], "3" is written in register Y in step A12, and if rl, lj, "4" is written in register Y in step A13. Also, in step A7, Xl, 2 of register X
If it is determined that the content of the digit is "sail 0", the process proceeds to step A14 and it is determined whether the content of the X3 digit of register X is [1] or "0". If the result of this judgment is "1", then in step A15,...7
Write "5" to star Y, and if it is "0", step A1
6, the contents of register Y are lowered by one digit. That is, if all of the X 1 +2 +3 digits of register X are rOJ, the contents of register Y that were carried up in step A4 are brought down in step Ale to return to the original state.

As described above, the register X contents detection circuit 13
The output signals T and -T3 of
” to “5” are input into the register YKi). And the above Stella 7'A.

AIO+ A12 + A13 + Als +
When the processing of Als is completed, the program proceeds to Stella fA17 and sets interrupt frizzo7o7''17 in preparation for the next input.

On the other hand, while the pencil input is being performed as described above, the output signals T□ to T3 of the detection circuit 13 are sent to the timer 20 via the OR circuit 19, and the timer 20 is cleared each time. However, when no written input is performed, the timer 2θ is not cleared and the counting operation of the clock A pulse φ continues. Then, after a certain period of time has elapsed, a carry signal is output from the timer 20 and input to the interrupt input terminal INT 2 of the CPU 15.

The CPU 15 connects timer 2 to the interrupt input terminal INT 2.
When a signal from 0 is given, it is determined that the handwritten input for one character is completed, the input/mother turn held in the register Y is recognized according to the flowchart shown in Figure 6, and then the delimiter is input. Translation processing is performed by

First, the interrupt flip-flop fl 7 is reset in Stella fB of FIG. 6, and the timer flip 70 21 is reset in step B2. Thereafter, the process proceeds to step B3, where the pattern data is compressed.

That is, the detection pattern of handwritten input characters is r12, for example.
34J.

If there are consecutive numbers like r54321J, replace the multiple numbers in between with 1 for "6" and create r164.
In addition, in the case of r5432jJ, r432J is replaced with "6" to become r561J. Thereafter, the process proceeds to step B4, where input character recognition processing is performed. That is, the input character is recognized by sequentially reading the pattern data from the four-turn memory 22 and comparing it with the detected pattern data. In step B4, if the character cannot be recognized, the process proceeds to step B5, where the buzzer 34 is activated to notify an error. Thereafter, in step B6, registers x, y.

2 is cleared, and the interrupt flip-flop 7'J7 is set as shown in step B7 to prepare for the next input.

If the input character is recognized in step B4, the process proceeds to step B8, where the character data for the matching pattern is read out and written into register A. Next, in step B9, it is determined whether the contents of the register A are a delimiter code that instructs translation, and if the contents are a delimiter sign code, the process proceeds to step B1o, where the translation end flag F3 is set.
``1'' is written in ``1'' and translation processing is performed in step Bll. That is, the dictionary memory 23 is searched for a word that matches the input word and translation is performed. If it is determined in step B9 that the contents of register A are not a delimiter code, then in Stella fBl, it is determined whether the contents of translation end flag F3 is "1) positive 0", and if it is "1", Stella Proceeding to fB13, rOJ is written in register B, and "0" is written in ic7/'F3 as shown in step B14. If it is determined in step B□2 that the content of the 1 flag F3 is "o", the process proceeds to step B16 and the content of the register B is incremented by one digit.

After completing the processing in step B14 or B15 above, proceed to step B1'6, and transfer the character data held in the A1 digit of register A to the first digit B of register B.
write to.

Next, in step B17, the contents of register B are written to register C, and as shown in step B18,
The contents of register C are sent to the character generator 25 and converted into 1,000 turn data. Even when the translation process of step Bll is completed, the process of Stella fB, 8 is performed.

The pattern data outputted from the character generator 25 is temporarily held in the shift register 27, then sent to the shift register 29, and displayed on the display section 6. Details of this data display processing will be described later. After that, step 8. At the same time, the recognition completion notification is issued, and the process proceeds to STAY 7' B 6 and the register X,
Y.

2 is cleared, and furthermore, as shown in step B7, the interrupt flip-flop 17 is set to prepare for the next input.

Next, details of the above display processing will be explained.
