Description

[Detailed description of the invention] (Technical field of invention) The present invention relates to a learning machine.

(Technical background of the invention and its problems) Various devices have been announced as learning machines, but they use computers to realize the principle of CAI, which is said to be the ideal teaching device, but these require programming. It's difficult.

Pointing out which words or numerical values are incorrect in sentences etc. has already been easily solved by the present invention as shown in Japanese Patent Application No. 56-020424. The problem is that it is difficult.

(Objective of the Invention) The object of the present invention is to design hardware to suit the purpose in order to eliminate the burden on programs.

Omitted words, excessive words, answers in sentences or many blank answers,
The purpose is to detect inversions and simple spelling errors, and to automatically correct errors without using software by simply inputting the answer into an input device when the incorrect marking is made with numbers, symbols, or continuous spelling. .

(Summary of the Invention) In order to achieve the above object, the present invention provides (the claims).

(Example of the invention) (Configuration of Example) An embodiment of the present invention will be described with reference to the drawings.

. . . Delay 27° for displaying . TM and HM are each circulated. Provide two period signals at the end of the sentence.

(Effect of the embodiment) When the problem is given and answered in Figure 1, the correct answer is given to the TM,
The answer is stored in the HM. /<The data of TM and HM are shifted by the pulse signal Cpf until a space (period) signal arrives in the shift register 1.1'. Comparison between correct and incorrect is performed by comparator 4. When consecutive spellings are long or short between the answer and the correct answer due to a mistake by the answerer, the pulse signal Cp is used to align the space signals. (ex, 15 cp,
<Cp) When the output (=) of the space comparator 5 is obtained, it is then shifted by the pulse signal Cps until the space signal arrives in the register 2.2'.

Figure 2 shows that when comparator 6.7.8 is only 6 (=), it is a continuous spelling (word) out of words, when only 7 (=) is an excess word, and when 6.7 is both (=) is inverted, and only 8 (=) is one consecutive misspelling.

In FIG. 3, if the comparator 4 is (←) between the shift pulses, these signals indicate that there is an error at that location.

In Fig. 4, if there is an error in the answer, it is stored in F, F, 20. After answering all the questions, next is the error signal 2.
2 is applied and scanning is performed using the space signal. Then mark the number of the incorrect part. A signal 23 for correction is applied and scanned. Then, the consecutive incorrect spellings are retained in register 1' by F, F, and 21. Correct your answers at this time. The sequence at this time is to clear register 1' and reverse the error detection shift register by one pulse. At the same time, the counter of the space comparator is decremented by one. Then, input the corrected answer followed by a space signal. This space signal is also used to clear F, F, and 21.

In FIG. 5, consecutive erroneous spellings are stored in the missword register 25. The next scan is then displayed on the data display 26. At this time, there is a delay in displaying numbers after consecutive misspelled numbers.

To summarize Figures 4 and 5: During the first scan, an error location is found in Figure 4.

Figure 5 shows consecutive incorrect spellings. μm in the missword register do.

During the second scan, error locations are indicated in Figure 4. fl)
, +31... In Figure 5, the data is displayed.

The problem is solved one by one depending on the signal when making corrections. To display all error numbers, all errors, and consecutive spellings at once, an error indication signal is applied and a start pulse is applied. To display one interval at a time, an error indication signal and a signal for correction are applied, and a start pulse is applied.

In FIG. 6, TM, HM, and register 1 are all circulated. If registers 1 and 1' are not the same, register 1
Bring the beginning of consecutive spellings of the content to the left edge. The contents of register 1' are cleared and the corrected answer is input. A pulse signal is obtained from this input and is used as a shift pulse for register 1.1'.

(Effects of Embodiment) As explained above, according to this embodiment, it not only points out where the incorrect answer is, but also points out omitted words, excessive words, and inverted words. When the data is to be corrected, it can be easily corrected since the data is in the register 1'.

The learning effect is enhanced because the answers are directly letters and numbers rather than choices, and errors are indicated either all at once or in parts, depending on the difficulty of the question, which also contributes to the learning effect.

When the output of the space comparator 5 is ~, Cp and >, Cp
A special AND is taken, and despite the simple structure, synchronization is achieved from the lack of characters in consecutive spellings and the state of extra characters, and it is easy to proceed to the correct or incorrect next character.

There are two periods (or questions, etc.) at the end of the answer, so you can check for omitted words and excessive words until the end.

(Effects of the Invention) As described above, according to the configuration of the present invention, it is possible to obtain great effects comparable to CAI with simple hardware.

Claims (1)

[Claims] The consecutive incorrect spellings and the next consecutive incorrect spellings are transferred to two serially connected shift registers, and the correct answer at that time is also present in another two shift registers. While detecting the type, the error detection shift register stores each consecutive error spelling location in a flip-flop and indicates it with numbers, symbols, and consecutive error spellings, and indicates all errors and one location at a time. There are two ways to do this: when you give a correction signal, the consecutive erroneous spellings are in a specific register, so clear this, and reverse the input counter of the error detection shift register and space comparator by one pulse. is a learning machine that can automatically correct errors by inputting answers and space signals into an input device, and has error detection without software and a correction function by the answerer.
