And a score calculation processing program 44 corresponding to the score calculation means.

The character recognition processing program 41, the calculation formula calculation processing program 42, the answer right / wrong judgment processing program 43 and the score calculation processing program 44 are stored in the ROM, but are stored in the RAM 30 or in an external storage area such as a hard disk. It may be stored.

Next, using the flowchart shown in FIG.
The operation of the present invention will be described.

First, when the system is started, the contents of the character pattern storage area 31, the calculation formula storage area 32, the answer storage area 33, the answer correct / incorrect storage area 34, and the score storage area 35 of FIG. 1 are cleared, and the step S21 of FIG. (Hereafter, S21
Abbreviated. The other steps are the same. In the formula input, a problematic formula is input. Here, the calculation formula (for example, 5 + 1 =) is written in one column of the problem calculation formula (A) on the screen of the touch panel as shown in FIG. At this time, 1
Each time a character is entered, a character recognition process 41 operates to recognize what character the character is, stores the character code of the recognized character in the calculation formula storage area 32, and displays it in the column where the character is written. You. When the stored character is "=", the process proceeds to S22. In S22, it is determined whether the end button E has been pressed.

If a character is written in the next column of the problem calculation formula (A), it is determined as S22 (No), and the mathematical expression is input again in S21. When the end button E is pressed (touched with the pen) in S22, it is determined that S22 (Yes),
Proceed to S23. At this time, the present operation learning machine is handed to the respondent. In S23, a mathematical expression calculation process is performed by the calculation formula calculation process. Here, each mathematical expression input in S21 and stored in the calculation expression storage area 32 is calculated, and the result is stored immediately after "=" in all the calculation expressions stored. At this time, it is not displayed at the position of the problem calculation formula (A) shown in FIG.

Next, the process proceeds to S24, where an answer input process is performed. Here, when a character is input in the answer column (B) of FIG. 3, the input character is recognized by the character recognition processing 41, and the value is stored in the answer storage area 33. Recognition of the end of the answer input is determined by whether the end button E is pressed. When the end button E is pressed, the process proceeds to S25, and a response correct / incorrect determination process is performed. Here, the calculation result calculated in S23 and stored in the calculation formula storage area 32 and the result stored in the response storage area 33 are compared by the answer right / wrong judgment processing 43, and whether the result answered in S24 is correct. It is determined whether it is wrong. Proceeding to S26, S
The result determined in step 25 is displayed in the right / false display area (C) of FIG. 3 as shown in FIG. At the same time, immediately after the equal sign of the problem calculation formula (A) in FIG. 3, all the contents stored in the calculation formula storage area 32 are displayed, and the calculation result performed in S23 is also displayed. Therefore, it is possible to confirm what the correct answer is here. That is, FIG. 3 shows the state before the fourth question 9-6 is answered and the end button E is pressed.

In S27, all the answers corresponding to the calculation formulas stored in the calculation formula storage area 32 are stored in the answer storage area 3
3 is determined. That is, it is determined whether answers have been made for all the questions in the question formula (A) in FIG.

If there is a question that has not been answered yet, the process proceeds to S24, and the process is started again from the input of a question that has not been answered. When all the questions have been answered, the process proceeds to S28, where the score calculation process 44 is executed to calculate the score. Here, the total number of questions input in S21 is S, and the number of questions determined to be correct in S25 is T
Then, T × 100 ÷ S is calculated and its value is displayed in the score display area D of FIG.

In the present embodiment, the formula calculation process S23 is configured to perform all the formula calculations of the problem input in S21 before the answer is input, but the answer is input one by one in S24. Each time, the formula of the problem may be calculated, and the correctness of the answer may be determined.

Next, another modified embodiment will be described. Although the arithmetic operation has been described in the above embodiment, the present invention can be applied to reading and writing of a language, for example, Japanese kanji. This example is shown below.

First, FIG. 4 is used instead of FIG. As can be seen from FIG. 4, instead of the calculation formula storage area 32, the phrase storage area 32A of FIG.
A idiom reading and searching program 42A is provided in the AM 30 and is stored in the ROM 40 instead of the calculation formula calculation processing program 42, and a idiom dictionary storage area 45 is added. Further, the flowchart of FIG. 5 is used instead of the flowchart of FIG. As can be seen from FIG. 5, S2 in FIG.
The mathematical operation of No. 3 is a process of extracting an answer from the idiom dictionary in S23A of FIG. In other words, in the above-described embodiment, the problem is mathematical operation, whereas in the modified embodiment, the problem is the reading of kanji. Therefore, in S23A of FIG. 5, the idiom dictionary reading and searching program 42A of FIG. From 45, the idiom notation storage area 32A
Is read, and the contents (reading) are stored in the answer storage area 33. Accordingly, the state of the touch panel 20 shown in FIG. 4 is as shown in FIG. 6, and when a reading answer is given to the kanji idiom problem, the correctness of the answer is automatically determined.

Also, if the correct answer is displayed at the position of the question formula (A) in FIG. 3 when the answer is entered as in the present embodiment, it is possible to confirm what the correct answer was. It becomes possible. In addition, by adopting such a system, it is possible to confirm without a third party what the wrong answer is and what the score is. Also, if you use this arithmetic learning machine,
The questioner can answer the question many times without thinking about the answer, eliminating the need to print the question and hand it to the answerer, prepare the answer and score each time as usual. In this way, an efficient learning mode can be performed.
