The signal T is written to the K signal 'r, and the third digit X. Further, the output signals T, ~T3 of the detection circuit 13 are sent to the pulse detection circuit 16, and their rising and rising edges are detected, and the pulse detection signals are passed through the AND circuit 18 to the pulse detection circuit 16.
'UJ 5's interrupt is manually input to S'lA child lNT1. In the above AND4b't<i8U, the "11" signal is always applied from the interrupt flip-flop 17, and the gate is kept at one voice with i'1t-1.
The output of the detection circuit 13 is sent to the timer 2o through the OR circuit 19 as a clear (number g).
” (When the number g is input, interrupt manual processing is performed according to the flowchart shown in FIG. 5, and a one-character pattern is created according to the character strength.

That is, as shown in step 5 of FIG. 5, 0PUJ5 first resets the interrupt flip-flop 20,
The gate of the AND circuit 18 is closed and subsequent interrupt input 6 is prohibited. Next step A! It is determined whether or not the timer 7 flip-flop 20 has been reset as shown in FIG. 1, step N.

If it is determined that the timer flip-flop 20 is set, the process directly proceeds to step A4.

In this step A, the contents of register Y are carried up by one digit, and then in step A, the interrupt signal is delayed by a minute time to generate a data read command, and the input data held in the manual boat 14 is transferred to register Transfer to.

In this case, the signal TI from the detection circuit 13 is the first digit of register X, X1, 4g, T, the second digit,
Enter the digit X. After that, proceed to step 1, determine whether the contents of the X34 digit of register X is [0, 0), and

A. *AIce AIfi+ AIS+ When the processing of Al1 is completed, the process proceeds to step 80, where the interrupt flip-flop J7 is set to prepare for the next input.

On the other hand, while the Hayabusa input is being performed as described above, the output signals T, ~T, of the detection circuit 3 are sent to the timer 20 via the OR circuit J9, and the output timer 20 is cleared. ing. However, when the manual force i+2 is no longer performed, the timer 20tfi is not cleared and the counting operation of the clock pulse φ continues. Then, after a certain period of time has elapsed, a carry signal is output from the timer 20, and 0PU
) 5 is input to the interrupt input cassette INT2.

0PU75I-t, when the signal from the timer 20 is given to the interrupt human input I NT2, #]V for one character
It is determined that the input has been completed, and the human cover turn held in the register Y is recognized according to the flowchart shown in FIG. 6, and if in the counting mode, the number of input characters is counted.

First, in step B1 of FIG. 6, the interrupt flip-flop J7 is reset.

In step B, timer flip-flop 2 is reset. Thereafter, the process proceeds to step B, where the pattern data is compressed. That is, when the detection pattern of elderly input characters is, for example, consecutive numbers such as "1234" and "54321", a plurality of numbers placed between them are replaced with one character "6" by 1α11. In other words, if the detection pattern is rl 234J, "23" is replaced with "23".

In the case of J, r432J is “6” Kw! , change to r5
s IJ. After that, proceed to step B4, and update the contents of register Y by three digits. Next, the process proceeds to step B4, and 7)' L/s register a and VC are set to "1". Thereafter, as shown in step B, the pattern memory 22 is accessed using the address data held in the address register s, and the pattern data 1' is sequentially outputted to the register 2. Then, in step B, the pattern data successively generated in register Z and the detected pattern data held in register Y are compared,
If they do not match, the contents of the address register a1 are incremented by r+IJ in step B, and then the process proceeds to step B8, where it is determined whether the contents of the address register 84 exceed the final address of the pattern memory 22 or not.

As a result of this judgment, if the content of a1 does not exceed the final address, the process returns to step Bll and repeats the same operation, and if it does exceed the final address, the process proceeds to step B14, where the speaker 27 is driven to notify the error. . Then step B.

The registers x, y, and z are cleared in step Bll, and the interrupt flip-flop 17 is set in step Bll to prepare for the next input.

If a match between the detected pattern and the standard pattern is obtained in step B6, the process proceeds to step Btt, where the character data corresponding to the matching pattern is read out from the pattern memory 22 and written to the register A. It's crowded. Then in step 13.3 the pin of register B]
At the same time, in step B14, the character data held in register A is transferred to register B.
Enter the first digit B. Then, the contents of register B are written to register C as shown in step B□. After that, the process proceeds to step B0, and it is determined whether or not the counting mode is on. If mode switch 11a is turned on and counting mode is specified, step B1? Proceed to count start flag F.

Write "1" to the number start flag F. Then step B. , the contents of count value storage register F are set to ``10l''.
"do. Also, the above step Bl? flag F1 in
If it is determined that the content of is "1", immediately proceed to step B. Process. After performing the processing in step h0, proceed to step B□, and insert the contents of register F into the upper digit OM of register 0. At the same time, in step B0, registers F and F are compared to match. . In this case, the desired number of characters is preset in register F3. The number of characters for this register F is set, for example, by specifying a mode and entering a numerical value by writing. Then, when the W+ value of register F, reaches the set value of register F, step 11.3
An alarm is notified at step B! 4
Welcome to.

Also, if it is determined in step Bt11 that the count mode is not in the counting mode, and if it is determined in step B that the count value of register F has not reached the set value of register F, the process also proceeds to step Bt4. move on. In this step B24, the data held in the register C, for example, the recognized character data and count value when in the measurement mode, are sent to the data buffer 26 via the character generator 25, and the display is displayed as shown in FIG. Display on 6. Thereafter, in step B□, a recognition completion notification is given, and the registers x, y, and z are cleared in Stella γB1o, and the process proceeds to step B11, where the interrupt flip-flop 17 is set to prepare for the next input. Input is recognized as described in item 1 above, and if the counting mode is specified, the recognized characters are counted.

In the above embodiment, switching to the counting mode was performed using a switch, but the switching may be performed by inputting specific characters with a pen.

In addition to addition, the number of recognized characters may be counted by subtraction from a preset value. In the case of English text, word breaks may be detected and spaces may be added as one character. Furthermore, calculations may be performed on the total v value, and the function designation at this time is performed using the keyboard, input, or keyboard.
