Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a learning device that controls a magnetic recording/reproducing device using control signals recorded on a magnetic tape.

Conventional configurations and their problems There are many types of learning devices that use magnetic tape, and there is a wide range of learning subjects and their contents. Magnetic tapes are often used in learning devices because they can be used for a wide range of recording purposes and are easy to use repeatedly. Particularly in language learning, the characteristics of devices using magnetic tape and the learning methods are very similar, so they are much more popular than devices in other learning fields1. Although CL conversation is given a lot of weight in TKNTF studies, it has been pointed out that 1.1's conversational skills are inferior to his Japanese translation ability in foreign languages. I'm here. However, the reality is that foreign language conversation education through school education is not provided at a sufficient level due to problems with Japan's examination system (1) lack of language education facilities (1+iii) or a lack of educators (3). Magnetic tapes compiled in the educational curriculum and their recording and reproducing equipment are widely used.

However, no matter how excellent the content of a magnetic tape may be, if the equipment used to record it is inconvenient to operate, it will cause negative effects on learning and reduce the educational effect. It's too late for WFJ. Therefore, in terms of software, efforts have been made to improve the calikilam that is blown into magnetic tapes, to improve sound quality, etc., and in terms of software, efforts have been made to improve the operability, functions, and other performance of recording and reproducing equipment. As a result, a so-called program scholar machine was proposed and put into practical use, in which the device performs predetermined operations to advance learning according to a certain curriculum.
I've been doing it.

J), -1・K rice science i"i' device explained 3
, Figure 1 is a diagram showing the recorded contents of the magnetic tape. In the figure, AK is 1, 1 is for stopping, 2 is for instructional audio, and 3 is for learning. Nagisa is t4T >; 3 minutes of teaching audio 2
When the learner wants to listen to his/her own voice recorded at that time, the learner rewinds the drive of the magnetic tape and the learning device detects the stop signal 1 recorded in advance on the magnetic tape. What is necessary is to automatically switch to the playback operation when However, this method has the disadvantage that when listening to the training audio again, the student must operate the learning device as described in Section 2.Also, if the student inadvertently crosses the next stop signal, However, when a student plays back a video, the part that the student wants to hear repeatedly cannot be played back, which is an inconvenience for learning.

Therefore, in order to eliminate these inconveniences, I recorded a signal after the training audio ended, and when this signal was detected, I tried to automatically perform the 1 f live action repeatedly. This is the one shown in Figure 1B.

As shown in Figure 1 B, 3 is a rewind signal, and at noon this signal 5 (,, detects/returns Ql, automatically moves to rewind operation, and from then on, the first As in the case of Figure A, it is only necessary to switch to playback operation when stop signal 1 is detected. However, with this 414 configuration, only &lJ: condolence repetitive learning is possible, so there is a risk that the teaching will be limited. In language learning, although it is suitable to some extent for pronunciation practice and vocabulary learning, it is difficult to prepare teaching materials that can provide sufficient practice for conversation practice, which requires responses.

FIG. 2 shows another conventional example. This is a format in which a question with multiple choices is asked, and students are asked to select the option they think is correct, and depending on whether the choice is correct or incorrect, the student is given a mesocene for each option.3.Figure 2K:l :
, -6 is a problem, and both R channels are the same. 7 is the correct answer message when the selection is correct, 8 is the incorrect answer message when the selection is full, 1 is the correct answer message, 4 is the correct answer signal, and 6 is the tape run. b) Stop signal 4 and stop signal 6 to stop
together.

This is from the R channel.

Third, in the block diagram of this conventional example, 9 and 10←
l, respectively L channel and R channel magnetic heads 11
and 12 are L channel and R channel Bria 7, respectively.
14 is a power amplifier for making the speaker 15 sound. With the 131-channel selector switch,
The connection between the L channel preamplifier 11, the R channel preamplifier 12, and the power amplifier 14 is switched. 16 is a signal detector and L channel preamplifier 11
and the output of the R channel preamplifier 12 are mixed to form the input fj signal. Reference numeral 17 is a microprocessor, and its peripheral circuitry includes a display 18, a memo IJ-19, a tape drive motor 20, and a key switch 21. Setusa 17 is having a good time.

Below, the details of this conventional example will be explained as follows: 152
Do this using the diagram and pigeon 3 diagram. , when the correct answer signal 4 is detected by the signal detector 16, the microphone [coprocessor 17C1
After this data is stored in the memory 19 and reproduced during the interval J5, when the signal detector 16 detects the stop sign 6, the tape drive motor 20 is stopped.

If there were three choices here, one would be ``IE 11'' and the remaining two would be incorrect.

. If the data input to the key switch 214 and the data stored in the memory 19 match, the micro processor 17 has a positive IQ! (The channel 1 switch 13 is then switched to the L side, and the tape drive motor 20 is driven to generate the correct answer message 7 of 4T NO.

Also, if the input data does not match the data in memory 1, it is considered an incorrect answer and the changeover switch 1
3 to the R side to drive the tape drive motor 20 and reproduce the incorrect answer message. This allows the learner to immediately know whether his/her answer is correct or incorrect, and by including instructions for the next career step in the correct/incorrect answer message, the learner or himself/herself can clarify the career path to take next. This makes learning easier.

Also, the answer is necessarily correct or incorrect.]
Since there is no lag, you can proceed with your learning with a quiz-like or tape-like feel, so you can maintain interest even if the learning content is a little stiff or difficult. On the other hand, from the standpoint of emphasizing an individual's individuality, characteristics, or creativity, this format of questions is not favorable and may hinder the growth of an individual. At the same time, with this structure, it is not possible to record one's own pronunciation and then play back the recorded sounds and compare them while learning.

As mentioned above, with the conventional structure, it is insufficient to provide sufficient teaching materials even if they try to provide sufficient educational effects, or students record their own pronunciation. It had a fatal drawback in that it was impossible to perform language learning (hereinafter referred to as LL learning) by playing back the audio and comparing it with the teaching audio.

Purpose of the Invention The present invention is a novel product that solves the above-mentioned conventional problems, and has a configuration that can fully utilize the functions of both the teaching month and the recording/playback device, thereby significantly increasing the learning effect.
．． The purpose is to provide educational bean making that will help students learn how to make bean paste.

Structure of the Invention The present invention provides a first control signal located at the beginning of each learning unit;
A second control signal located at a division part of the learning content in the learning unit, the /C information located at the end of the learning unit and controlling the magnetic recording/reproducing device, and the learning unit number as data. A third control signal containing the 115th report is recorded. a magnetic tape, a detector for the first and second control signals, and a control information included in the third control signal.
a WrVc device that transmits 'l'l'fil; a learning unit number storage device that stores the learning unit number included in the third control signal when the third control signal is received; and the learning unit stored in the storage device; a unit number display device for displaying a unit number to a scholar; and the first unit number display device. a progress counter that adds up the number of times the second and third control signals have been received; a switching device that switches the operation of the magnetic recording/reproducing device when the value of the progress counter changes; The learning unit number received is compared with the learning unit number stored in the learning unit number storage device, and if they do not match, the newly received learning unit number is incremented by 1 and the learning unit number is stored in the learning unit number storage device. The learning device is equipped with a learning unit number ratio axis device that stores the value of the progress counter in the device and resets the value of the progress counter to 0, and each time a third control change is received, the learning unit number is included in the control signal. By comparing the numbers and resetting the progress counter value to 0 if the numbers are different, and setting the learning for each m element to the initial state, you can skip over one or more units and learn. This makes it possible to start studying from a unit in the middle, so-called skip learning or intermediate learning. In addition, by switching the magnetic recording and playback device to the recording state when the progress counter value is reset to ○, you can start unit study 4'2 without fail in the recording state, simplifying the operation. This allows for more ambiguous skipping learning and intermediate learning. Of course, it is basic that the learning materials created for learning are followed in order according to the learning process, but depending on each individual's aptitude and ability,
Depending on the person, it may be more appropriate for some people to proceed by skipping parts of the learning process little by little. For example, if a course of study consists of a combination of three sections: basic part, practice part, and applied part, it may be difficult for people who are quick to understand to finish learning the basic part, skip learning the practice part, and move on to the applied part. In many cases, students will lose less time and be able to study more efficiently if they move to another department. The present invention is capable of supporting skip learning in such cases, and also has a function to display unit numbers, in which case the present invention can display the unit number of the part being played or recorded and the unit number displayed by the learning device. are properly synchronized. Furthermore, even when learning is automatically progressed by making full use of playback, recording, or rewinding functions between control signals within a unit, skip learning can be performed without any problem regardless of the state of the drive device. It is possible to do so. Furthermore, even if the device has a display function of displaying the learned unit number or the correct answer rate, it can be displayed correctly when skip learning or intermediate learning is performed. Note that the skipping learning in the following explanation includes both the case of skipping forward and the case of going backwards and skipping over the learning section 4):.

Just like normal recording and playback of 2 tracks 1 channel, normal recording and playback of 4 tracks 2 channels, and 4 tracks 2
a selector switch that switches between recording and playback modes that control program learning by receiving control signals that are channeled and pre-recorded on magnetic tape;
When the position of the selector switch is moved, the magnetic recording/reproducing device is equipped with a selector switching detection device that outputs an output that switches the magnetic recording/reproducing device to a stopped state, so that the track usage or operation method on the magnetic tape can be changed between different modes. On the other hand, when the selector switch is moved, the magnetic recording/reproducing device is automatically switched to a stopped state, which leads to improved operability and increased learning effect.

Historically, the selector switch detection device detects magnetic recording and playback when the selector switch position is switched from the recording/playback position for controlling program learning to the normal recording/playback position for 4-track, 2-channel. 7, a selector switching detection device that outputs an output that continues in the operation that allows you to go to the normal recording and playback mode, lt
,,When switching from the program learning control position to the normal recording and playback position in 7, the magnetic recording device line is not stopped. By continuing to play the operations, it is possible to easily switch between program learning and normal LL learning, and it is also possible to easily change the configuration of LL learning to suit an individual's aptitude and ability.

83 and 84 are both educational voices, but 83 is an explanation or practice part, and 84 is a part corresponding to problems, questions, or the other party in a conversation.

Hereinafter, 83 will be referred to as the training practice audio, and 84 will be referred to as the training question audio. A first control signal 80 . before the teaching practice audio 83 . Also, a second control signal 81 is placed before the training question audio 84, but during playback or recording, the first control signal 80. Neither the second control signal 81 nor the second control signal 81 is detected, and when the third control signal after the training question voice 84 is received, the operation is switched. 85 is the part where the learner's utterances are recorded.

Next, the operation of the present invention will be explained using FIGS. 5 and 6. Note that in the initial state, the value of the progress counter is 0.

Since all control signals recorded on the magnetic tape 49 are recorded on the L channel, they are transmitted through the L channel magnetic head 5o. For this reason, the L channel preamplifier 52 is always in a reproducing state, and the blank detector 69. The control signal detector 70 and the control signal demodulator are always in a state where signals can be input. magnetic tape 4
When the third control signal 82 recorded in 9 is picked up by the L channel magnetic head 5o, it is converted by the control signal demodulator 71 into a time series of 111 times of ``On'' and ``1'', and is sent to the control information decoder. At 72, the data is converted into respective data.

The microprocessor 60 checks the correctness of the data, and if it is determined that the data has been received legitimately, the microprocessor 60 includes 1 in the control information.
i (unit number storage area 76 in AM76)
c and output to the unit number/month display device 64 for display, and after incrementing the progress counter by 1, the drive device 6 completion 3 is changed based on the first switching means 77a written in the ROM 77. At the position where the magnetic head contacts the magnetic tape 49, the state is switched to rewinding, and after the progress counter 8 is further incremented by 1, the output of the control signal detector 70 is monitored.

At the tape speed of rewinding, the second control signal 81 is 400~
Since this is 700 Hz, this is detected and input to the microprocessor 60, and the progress counter 78 is incremented by 1, and after it reaches 3, the drive device 73 is switched to the regeneration state based on the second switching means 77b. By turning on the switch 64 and turning off the recording amplifier 58, the audio 2f
Equipment 59 [Replace 11N raw state helicopter]

When the 11th third control signal 82 is received, the progress color/result 8 is added by 1 to 4, and the drive device 73 is stopped based on the third switching means 77c, and the learning πr value is displayed in blue. For example, the characters "' P U S H" on the device 3,
The corresponding unit number is displayed on the unit number display device 64, and the operation switch (, l,
It flashes to display 117t. The operation switches to be input here correspond to the progress switch 62b and the review switch 62c in the embodiment.

When the learner presses the review switch 62c, the progress counter 7
8 is added by 1, and becomes 5. Similarly to the case of the first switching means, the drive device 73 causes the magnetic head 60° 51 to switch to the magnetic tape 4.
9, the output of the control signal detector 70 is monitored.3, the second control signal 81 is detected, the first control signal 80 is further detected, and this is sent to the microprocessor 60. When the input is input, the progress counter 78 is incremented by 1 and becomes 6, and the fourth switching means 7yd causes the drive device 73 to enter the playback state, and by turning on the selector switch 54 and turning off the recording amplifier 68, the audio device 59 is turned on. When the playback of the 33 tape progresses and the third :llll monk 1 signal 82 is received, the progress counter 78 becomes 1 horn 3') and becomes 7.
At this time, it is reset to O, and based on the fifth switching means 77e, the changeover switch 54 is turned off and the recording amplifier 58 is turned on, thereby switching the audio device 59 to the recording state. It is basic to record one's own vocalizations at the same time, and in the structure of the present invention, the study of units is not skipped and starts by recording one's own vocalizations in accordance with the teaching practice audio 83. When you finish studying and move on to the next unit, it is best to leave it in recording mode. By doing this, there is no need to make any special operations or considerations for the learners, and apart from that, it is extremely useful when creating relationships between adjacent learning units and creating continuity. convenient. Note that when switching from the live state to the recording state, the drive device 73 does not need to be activated because it operates in the same way in either the playback or recording state.

When the learner presses the progress switch 62b during the learner's self-evaluation, the microprocessor 6° switches the drive device γ3 from the stop state to the playback state, and the magnetic tape 4
9 starts driving. At the same time, the changeover switch 54 is turned off and the recording Qf amplifier 68 is turned on, thereby switching the audio device 69 to the recording state and proceeding to learning the next unit. The reason for switching to the recording state here is the same as the reason stated in the explanation of the fifth switching means.

Next, when the third control signal is received, this belief includes 1
The operation when the learning unit number stored in the learning unit number storage area 76c does not match the unit number stored in the learning unit number storage area 76c will be explained.

For example, when the progress counter is 3 (in this case, it is in the playback state), the tape running is stopped and the selector switch 29 is pressed.
(Fig. 4) to the 'LL' or 'NORMAL' position, operate the fast forward switch 30d (Fig. 4),
Suppose we skip over the number rJ'. In addition, at this time d
:If you use the function of Gyu (fast forwarding with the magnetic head in pressure contact with the magnetic tape, and fast forwarding while the sound is being played in LIF), you can postpone the unit without confirming its existence. Since this operation is common, I will omit the explanation.3゜Now, with the above operation, we have successfully skipped the !1'1 yuan, so press the selector switch 29 again.'' iVI IC
If the learning start switch 31a is operated in the "OM" position, program learning will be restarted.1.Hereafter, the explanation will be given again using FIG. 6.Learning start switch 62
When a is operated, the blank detector 69 function is used to locate the beginning of the sentence, and then the 5 drive device 73 and the audio device 69 enter the playback state.

After that, when the third control signal is received, the learning 1112 element number comparison device 79 compares the unit number included in this control signal with the unit number stored in the unit number storage area 76c in RAMYe. do. In this case, for example, if the former is 6 and the latter is 4, the student numbers do not match, so the following actions must be performed at -93 degrees to the right of the received unit number, in this example 6. Add 1 to 7 and store it in which unit number storage area 76c 3
At this time, Unit No. 4, which had already been stored, automatically disappears due to the structure of the storage area. Next, by the action of 33 and above that resets the value of the progress counter 78 to O, in the former case, the new unit number 7 is displayed on the unit number display device 64, and in the latter case, by resetting the progress counter 78, the audio device Switch 5″9 to recording mode.

Note that the drive device 73 is in the playback state and is the same in the recording state, so there is no need to change it.

To explain the second operation in an easy-to-understand manner, when operating the selector switch 29 to perform a jump operation, it is sufficient to stop before the third control signal. Even if this control signal passes through WakaI''-, there is no problem because the sentence repeat function will rewind the portion of the signal that has passed.This third control signal is It is located between unit 6 and unit 7,
Strictly speaking, this is a signal that is not used to control the units, so if you add 1 to this, it becomes the next unit, that is, the number 70.3.With this method, e) interrupting the learning of element 4, Skip Units 6 and 6, QQ, and study Unit 7')! ? That is why it was moved to. Naturally, learning in Unit 7 can be started from the initial state, so this is extremely convenient for learning.1 Next, the operation when the selector switch 29 is moved will be explained. In this example, d, selector switch f 29 (7) position is "NORMAL'' L L
” ” MI COM ” No 3 Kaaruka,”
NORMAL” has 2 tracks and 1 channel, and “L”
L" and "MI COM" are 4 trunks and 2 channels, and the usage status on the magnetic tape is different. When the K selector switch 29 is moved during operation (while the magnetic tape is running), the magnetic recording 1J production device It is not good for learning to continue the action for one inch.

In particular, in the recording mode, the instructional audio portion may be erased or double-recorded, so when the selector switch is moved, at least the [H
1* Must not be continued. Also, “LL” and Q,”
The same track is used between MICOM'' modes, but when switching from ``LL'' to ``MICOM'', the operation in ``LL'' mode before switching must be specific in order to maintain continuity in program learning. Must be realistic.

When the selector switch 29 is moved on the operation surface, it is better to stop the operation. However, on the contrary, “M I
When switching from ``COM'' to ``LL'', there is no problem with the track - it is better to continue C1 operation -i
L. Rather, when the learner wants to do learning that is not included in the program during program learning, such as repetitive learning that involves a considerable number of repetitions, the selector switch 29 should be turned to L.
Although we will move to the L example, it is more efficient for learning to continue the previous movement as it is at this time.

Among the above, in cases where it is better not to continue the operation, the methods to avoid this are to structurally prevent the selector switch 29 from moving when the magnetic recording/reproducing device is not in a stopped state, or to The operation of the FRT selector switch 29 causes the magnetic recording/reproducing device to be stopped, but in the case of the former, Q-1, after the recording device is stopped using the operating switch, Whereas it is necessary to change the mode with the selector switch 29,
The latter is superior in operability because the mode can be changed directly with the selector switch 29 no matter what state the child device is in. 1 In FIG. 6, it is assumed that the selector switch 91 is at the switch position II/1 of 91a, that is, 'N0R1viAL''.The position of the selector switch 91 is constantly monitored by the microprocessor 60, and the selector switch To facilitate detection when the 91st digit 1r1 is moved, the position of the selector switch 91 is encoded so that, for example, "NORMAL" is O, "LL" is 1+ "J・d I COM" ij 2 + J
a) and store it in the RAM 7e.

The microprocessor 60 always operates as a selector switch 91
Electrically input the position of , compare it with the selector input data in the RAM 76, and if the value is different, change the drive device 73 and audio device 59 to the stopped state. Switch 91 is in position 91C
('”MICOM”) to 91b (”LL”)
When the drive device 73 and the audio device 59 are in any state, they continue to operate within the range of operating states allowed in the °' L L " mode.

To explain this with a specific example, for example, when playing or recording, it continues as it is, but in the case of review (rewinding while playing the sound with the magnetic head in pressure contact with the magnetic tape), "LL" ” mode, this operation is performed while the rewind switch 30c (Fig. 4) is held down.
Therefore, when the selector switch 91 is moved, the operation is the same as when the second rewind switch 30c is pressed and released, and the switch to playback is performed. It will maintain continuity. It should be noted that in the above explanation, the operations involving the microprocessor 60 are performed by executing the 100 million program recorded in advance in the RO1VI77. Next, using a flowchart, a processing procedure centered on the operation of the microprocessor will be explained.

Figure 7 mainly shows the operation of the microprocessor in this embodiment! (1) This is the main flowchart 1 of one step. In the explanation of flowchart 1, each processing unit will be called a step. 3. In FIG. It takes. Step 10
2 is a process for setting the logic of the terminals of the microprocessor to the initial state, setting the value of the counter to O, or setting the state of the memory to the initial state. Step 103 detects whether the magnetic tape 49 is correctly set on the tape drive base of the learning device, and flags the attachment/detachment of the magnetic tape 49 (in this explanation, a 1-bit flag indicating a certain state) is detected. (pointing to memory) is set to 0 or 1.

A flowchart of this step 103 (magnetic tape detection) is shown in FIG.

Step 104 involves inputting the on/off state of the switch from the terminal of the microprocessor 60 after chattering occurring at the contact portion of the switch is removed in the operation switch 620 input processing.

Step 105 determines whether a switch has been turned on based on the data input in step 104. If the switch has been turned on, the process branches to step 106 of operation switch input processing. A flowchart of this step 106 is shown in FIG.

In step 107, it is determined whether or not audio control is necessary. If necessary, the process branches to step 108. The flowchart of this step 108 is
The result will be as shown in Figure 0. Step 109 is the driving device 73
The process branches to step 110 if necessary.

In step 111, it is determined whether the selector switch (29 in FIG. 4) is in the position of "=ra I B oxa". In other words, it is determined whether or not program learning is being performed. If it is in the position of "MICOM", the process branches to step Proceed to the processing below 212, and
If it is not the position of ``I COM'', step 10
Go back to step 3 and repeat the previous steps.

Step 112 is a part for determining whether a display instruction is given, and if there is an instruction, the process branches to step 113 for display. Note that this instruction is made using the flag mentioned in WI. In step 114, it is determined whether or not the third control signal is input. If so, the process branches to step 116 and the control information is decoded. Step 116 is the first or second
It is determined whether or not a control signal is input, and if so, the process branches to step 117 to count the signals and proceed to a predetermined operation. In step 118, it is determined whether or not the decoding of the control information in step 115 has been completed. If the decoding of the control information has been completed, the process branches to step 119 and proceeds to a predetermined operation. The deviation in the completion of these operations is caused by the position of the selector switch 29 at step 111 being "MI CO".
Return to step 103 as in the case other than the M" position.

FIG. 9(a) is a flowchart 1 depicting step 106 in FIG. 7 in detail. In FIG. 9(a), slaps 128 and 129 are selector switches 29
When (Figure 4) is operated, the drive device is stopped to avoid discrepancies in the recording tracks when used as a LL scholar (LL) and a normal tape recorder (NORMAL), or confusion in r1 program learning. It's no good. Step 130 is for distinguishing whether the selector switch 29 is in the "MI CON" position or in any other position %I, and distributing the operation of each switch. In the case of "MICOM", the operation is divided into operations corresponding to each switch in the program learning operation switch group 31 in FIG. 4. This corresponds to each step from slap 131 to step 140 in each operation of learning start, stop display, progress, or review.

In cases other than "MICOM", the operations are similarly assigned to the operations corresponding to each of the general operation control groups 30 in FIG. 4. These operations include playback, recording, pause, fast forward, rewind, and stop operations, and each step from step 141 to step 152J corresponds to this operation. .

FIG. 9(b) is a flowchart in which the function of detecting the movement of the selector switch 29 has been further increased, and since it is not significantly different from that in FIG.
Display in 52 inch size is omitted.

In FIG. 9(b), step 128
The selector switch 29 is the same as the explanation in FIG.
(91 in FIG. 5) is determined to have moved in the step of detecting movement, the process branches to step 251. In step 251, it is checked whether the movement of the selector switch 29 is from ``MICOM'' to ``LL'', and if so, the 9th
The process branches to step 129 as in the case of FIG. Further, when moving from 'MIC○14' to 'LL', the process branches to step 252.

In step 252, in the case of continuation of operation in the 'LL'' mote, the procedure for continuation of operation regarding the review and cue described above is performed.Specifically, the rewind switch 30 is pressed.
Nt from the state where c or instep feed switch 3od is held down:
I, the state is set on the program. Next, the process advances to step 130, after which the process explained in FIG. 9(a) is performed, and from "MI COM"'
The operation in °'L L'' mode when switching to L L'' is continued.

FIG. 11(a) is a flowchart depicting the display step 113 in FIG. 7 in detail. In FIG. 11(a), step 166 determines whether or not there is a request to display the proficiency level. If there is a request to display the proficiency level, the progress switch (62b in FIG. Did you press the review switch (fifth) yet?
This is a step in which the number of times 62C) in the figure is pressed is memorized and the ratio of the sum of the number of times 31 of pressing and the number of times the review switch is pressed is calculated. Step 168 is a process of outputting the calculation result and performing a blinking display operation. Step 169 is a process of determining whether the self-evaluation is being displayed (r4) and continuing the blinking operation during the display operation.
1 and 172 are steps for displaying a unit number if there is one.

FIG. 11(b) is a flowchart illustrating in detail step 116 of reading the control information one evening in FIG. 1st
In FIG. 1(b), it is determined in step 176 whether the signal includes id information, and if so, it is regarded as a third control signal and a command is given to receive the information part in step 177, and the process returns to the main routine once. . Next, when the program returns to step 175, a data reception command has been issued, so the program branches to step 178 at step 176. If data has been received, it is sequentially stored in the RAM (76 in FIG. 5) (step 179). Note that this routine only receives and decodes data, and does not perform any operations using the data. FIG. 11(c) is a flowchart depicting in detail step 117 of control signal detection in FIG. In FIG. 11(C), step 1
82 is a control signal (the first control signal and the second control signal in FIG.
If there is an input, the number of times the control signal is detected is N, which branches to step 183.
Then, in step 183, the number N is increased by one.

If it is N-1 in step 184, step 18
5 and 186, N is set to 0, and the recording/playback device is switched to playback. In this embodiment, the operating state of the program learning is divided into six states, each of which is assigned a number from 1 to 6, and is represented by a memory l called LL, and the program learning is controlled by the number. The number increases as the program learning progresses, and this step 185 also corresponds to switching the program learning (corresponding to the second switching means in FIG. 5), so the value of LL is increased by 1. I'm letting you do it.

Further, step 187 branches to step 188 when N=2, and in steps 188 and 189, step 185
and 186.

Note that here as well, the value of LL is increased by 1 since this corresponds to switching of program learning (corresponding to the fourth switching means in FIG. 5).

Figure 12 shows step 11 of study deposit 1j in Figure 7.
In FIG. 12, steps 214 and below are particularly relevant to the present invention, and step 214 indicates that the data type of the received third control signal is a unit For control, step 21
5 or less branches. 1 of program learning when LL=1
．． Since this corresponds to the first switching means (corresponding to the first switching means in FIG. 5), in step 216, the drive device 3 (FIG. 6) is switched to the rewinding operation, and in step 218, LL is increased by 1. 1. Even when LL=3, the drive device completes 3 (
5), and in step 221 a display prompting self-evaluation is displayed. Also at this time, the value of LL is increased by 1 in step 218.

Next, when LL=e, the audio device 59 (FIG. 5) is switched to the recording state at step 223, which corresponds to switching of program learning (corresponding to the fifth switching means in FIG. 5).

Although the following explanation uses a cassette tape as the magnetic tape, the present invention is not limited to whether or not the magnetic tape is in a magazine. Also, I explained using LEDs for various displays,
This invention also does not limit the parts used for display in any way, and can be realized using other display materials, such as a liquid crystal display or printed matter. Furthermore, although the embodiments have been mainly explained using a microscopic sensor, it goes without saying that the scope of the present invention may be realized even if part or all of the microprocessor is implemented using a logic circuit or the like.

A second control signal located at a dividing part of the learning content in the learning unit, and information located at the end of the learning unit for controlling the magnetic recording and reproducing device and information containing the learning unit number as data. a magnetic tape having a third control signal recorded thereon; a detector for the first and second control signals; a decoder for decoding the control information included in the third control signal; In this case, a learning unit number storage device stores the number of the learning unit included in the signal, and a learning unit number storage device stores the learning unit number stored in the storage device. a unit number display device that displays the unit number; a progress counter that adds up the number of times the first, second, and third control signals have been received; and when the value of the progress counter changes, A switching device that switches the operation of the magnetic recording/reproducing device compares the learning unit number included in the received control signal with the learning unit number stored in the learning unit number storage device and determines whether they match. (including a learning unit number comparison device that adds 1 to the newly received learning unit number and stores it in the learning unit number storage device and resets the value of the progress counter to 0).
Each time a control signal is received, the learning unit numbers included in the control signal are compared, and if the numbers are different, the progress counter value is reset to 0, and the learning for each unit is returned to the initial state. The ability to continuously perform so-called skip learning or intermediate learning, in which one or more units can be skipped over or started from a unit in the middle, has become KO Ding Noh. By switching the magnetic recording and reproducing device to the recording state when the value of the progress counter reaches O, unit learning can always be started in the recording state, simplifying operation. The effects of skip learning and mid-course learning are remarkable. 1. Learning methods can be chosen with a considerable degree of freedom depending on an individual's aptitude and ability. 2. The effects are remarkable. .

Just like normal recording and playback of 2 tracks and 1 channel, normal recording and playback of 4 tracks and 2 channels, and 4 tracks and 2 channels.
A selector switch that switches between recording and playback modes that controls programming and learning by receiving control signals that are recorded on a magnetic tape in advance. Equipped with a selector switching detection device that outputs an output to switch the device to a stopped state, when the selector switch is moved between modes that use different tracks on the magnetic tape or have different operating methods, magnetic, The recording/reproducing device can be automatically switched to a stopped state, and malfunctions can be prevented.

Furthermore, the selector switch detection device detects when the selector switch position is 4 tracks, 2 channels, and controls program learning. By making the magnetic recording and playback device output a continuous output while operating in the normal recording and playback mode, it is particularly effective when switching from the position where program learning control and 11i are performed to the position 1 of normal recording and playback. By allowing the magnetic recording and reproducing device to continue operating without stopping, it is possible to easily switch between program learning and normal LL learning, and it is also possible to easily configure learning according to an individual's aptitude and ability. , which can be expected to have a great effect on learning.
