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 Structures and Problems There are many types of learning devices that use magnetic tape, and there are a wide range of subjects and contents. Needless to say, magnetic tapes are often used in learning devices because they can be recorded and can be easily used repeatedly. ``In language learning, the characteristics of devices using magnetic tape and the learning method closely match, so they are far more popular than devices in other learning fields. Conversation plays a large role in this field, and it has been pointed out that Japanese people's conversational skills are inferior to their ability to translate foreign languages into Japanese.However, foreign language conversation education through school education is Problem with the Japanese examination system Problem 1: The reality is that language education is not being conducted at a sufficient level 1 due to deficiencies in language education equipment or a lack of educators. Recording and playback equipment has become widespread and in use.

However, no matter how excellent the content of a magnetic tape is published, if the equipment used to record and play it is inconvenient to operate, this will likely act as a negative factor in learning and reduce the educational effect. There is no need to talk about it now. Therefore, in terms of software, improvements were made to the curriculum written on magnetic tape and to improvements in sound quality, and in terms of hardware, improvements were made to improve the operability, functionality, reliability, etc. of recording and playback equipment.
I've been trying to do the second thing. As a result, so-called program learning machines have been proposed and put into practical use, in which devices perform predetermined operations to advance learning according to a certain curriculum.

A conventional learning device will be explained below. Figure 1 is a diagram showing the recorded contents of the magnetic tape. (In ~, 1 is the stop signal and 2 is the instructional audio. The learner wants to listen to the instructional audio part 2. When the learner wants to listen to his or her own voice recorded at that time, the learner rewinds the drive of the magnetic tape, and when the learning device detects the stop signal 1 recorded in advance on the magnetic tape, the learner automatically starts the playback operation. However, this method has the drawback that the learner must operate the learning device as described above when listening to the teaching audio again. If you play beyond the number,
This creates an inconvenience when learning because the parts that the learner wants to hear repeatedly cannot be played back.

Therefore, in order to eliminate these inconveniences, we recorded a signal after the training audio ended, and when this signal was detected, we tried to automatically repeat the playback operation, as shown in Figure 1 ( B).

In Fig. 1 (B), 3 is a rewind signal, and when this signal is detected during playback, the rewind operation is automatically started. 'ff
: All you have to do is switch to playback mode when it is detected.

However, this structure only allows for repeated learning, so there is a risk that the teaching materials are limited, and although it is suitable to some extent for one-pronunciation practice and word scholars in language learning,
In conversation practice where receiving and responding to a conversation requires a response, it is difficult to prepare teaching materials that allow sufficient practice.OFigure 2 is another conventional example. This is a format in which a question with multiple choices is asked, and students are asked to choose the numbered option that they think is correct, and a message is given for each choice depending on whether the choice is correct or incorrect. In Figure 2, 6 is a problem,
Both R channels are the same. 7 is a correct answer message when the selection is correct, and 8 is an incorrect answer message when the selection is incorrect. Further, 4 is a correct answer signal containing the correct answer number, and 6 is a stop signal for stopping tape running. Both correct answer signal 4 and stop signal 6 are the same for the R channel.

FIG. 3 is a schematic diagram of this conventional example, where 9 and 10 are L channel and R channel magnetic heads 11 and 12, respectively.
are the L channel and R channel preamplifiers, respectively, 14
is a power amplifier that cannot make the speaker 16 sound. Reference numeral 13 denotes a channel changeover switch for switching the connection between the L channel preamplifier 11, the R channel preamplifier 12, and the power amplifier 14. 16 is a signal detector which uses a mixture of the outputs of the L channel preamplifier 11 and the R channel preamplifier 12 as a human signal. 17 is a microprocessor, and its peripheral circuitry includes a display 18. It has a memory 19, a tape drive motor 20, and a key switch 21, and the channel changeover switch 13 is also controlled by the microprocessor 17.

The operation of this conventional example will be explained below with reference to FIGS. 2 and 3. When the correct answer signal 4 is detected by the signal detector 16, the microprocessor 17 stores this data in the memory 19. After problem 5 is played, signal detector 1
When the stop signal 6 is detected at step 6, the tape drive motor 20
to stop.

If there are three choices here, one will be correct and the remaining two will be incorrect. The student enters the number he or she thinks is correct using the key switch 21.

If the data manually inputted from the key switch 21 matches the data stored in the memory 19-\, the microprocessor 17 determines that the answer is correct and switches the channel selector switch 13 to the L side, drives the tape drive motor 2o, and sends a correct answer message. Play 7.

If the input data does not match the data in the memory 19, it will be treated as an incorrect answer and the channel changeover switch 13
Switching to the iR side, the tape drive motor 2o is driven to reproduce the incorrect answer message. This allows the learner to immediately know whether his or her answer is correct or incorrect, as well as confirm the correct answer,
By including instructions for the next career step in the incorrect answer message, the learner can easily proceed with learning because the career path he or she should take next becomes clear.

Since the answer is always either correct or incorrect, you can proceed with learning in a quiz-like or game-like manner, so it is easier to learn even if the content is a little stiff or difficult. I can't help but lose interest. On the other hand, from the standpoint of emphasizing an individual's individuality, characteristics, or creativity, this question format is not desirable and may impede an individual's growth. 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 shown in Figure 2 above, with the conventional structure, there are cases in which the teaching materials needed to achieve sufficient educational effects are not provided, or they are insufficient, or students record their own pronunciation. It had the fatal drawback of not being able to perform language learning (hereinafter referred to as LL learning) by playing it back and comparing it with the IA voice for instruction.

Unfortunately, since the signals recorded on the magnetic tape are detected during rewinding, which is unstable when the magnetic tape is running, there is a risk that the signal detection may become unstable.

Purpose of the Invention The present invention is a novel device that solves the conventional problems mentioned above, and provides a learning device that is configured to fully utilize the functions of both the teaching material and the recording/playback device, thereby significantly increasing the learning effect. The purpose is to provide

By associating this with the count of LL, it is possible to configure a program learning that allows appropriate review, and it is possible to improve the efficiency of LL learning and achieve reliable operation control.

In addition, if the control signals recorded on the magnetic tape have the same frequency and are differentiated by making a difference in their continuous time, that is, the length of the signal, the configuration for detecting the control signal can be simplified. This is something that can be provided.

Figure 6 is a schematic representation of signals recorded on a magnetic tape in accordance with an embodiment of the present invention.

80 is a first control signal, 81 is a second control signal, and 82
is the third control signal. As mentioned above, 50 Hz sine waves are used, but in order to distinguish between them, the lengths are set to, for example, 1 second, 2 seconds, and 3 seconds, respectively. Alternatively, in order to distinguish each control signal, a method may be adopted in which the frequency of each control signal is changed. For example, the first control signal is 50H2, the second control signal I''i, 1 ooHz, and the third control signal is 3 KHz.
It may be done as follows.

There is also a method of distinguishing by the number of signals. For example, set a continuous sine wave signal of about 0.5 seconds as a unit signal, continue the signal for 0.6 seconds, leave the next 0.6 seconds blank, and when there is one signal, use the first control signal, and when there are two signals, When , the second control signal, 3
In the case of 1, it is better to use the third control signal. As mentioned above, there are several types of control signal systems, but in this example, we will explain a system that distinguishes them based on the difference in continuous time of the signal.Both 083 and 84 are training voices, but 83 is for explanation or practice. 84 is the part corresponding to the other party in the problem, question, or 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. Further, 85 is a recording portion of the learner's utterances.

Next, the operation of the present invention will be explained using FIGS. 5 and 6.

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 60. For this reason, the L channel preamplifier 52 is always in a reproducing state, and the blank detector 69. The control 1il11 signal detector 70 is always in a state where signals can be input.

When the first control signal recorded on the magnetic tape 49 is detected, the first tape counter 76a is reset to the initial state and the pulse sent from the reel unit number pulse generator 67 is input to the microprocessor 60. The first tape counter 76a is incremented by 1 each time. next,
When the second control signal is detected, the second tape counter 76b, which is reset to the paddy amount state, increments by 1 every time a pulse is input, similarly to when the first control signal is detected.
Note that the first . The second and third determinations are made based on the continuous time of the signal as described above, and this determination uses the operating clock necessary for the operation of the microprocessor 60 as a reference for time comparison.

Next, when the third control signal is detected, the drive device 73 changes based on the first switching means 77a written in the ROM 77 and set to the appropriate size.
is switched to rewind and the second tape counter is switched to subtraction. As a result, the value of the second tape counter 7eb is decremented by 1 each time a Noculus is sent from the reel table rotation pulse generator 67, and when this value becomes 0, the second tape counter 7eb is activated based on the second switching means 77b. The device 73 enters the playback state, and the audio device 69 is switched to the playback state by turning on the changeover switch 54 and turning off the recording amplifier 58.

When the third control signal 82 is detected again in this reproducing state, the drive device 73 is stopped based on the third switching means 77C, and the learning evaluation display device 63 displays, for example, "P U
The letters "S H", the corresponding unit number on the unit number display device 64, and the position of the operation switch to be input are flashed on the self-evaluation input switch display device. switch 62
b and review switch 62c.

When the learner presses the review switch 62c, the drive device 73 is switched to the rewinding state and the first tape counter is switched to the subtracting state as in the case of the first switching means. Due to this, reel stand 1. Every time a pulse is sent from the ijj pulse generator 67, the first tape counter 76
When the value of a is subtracted by 1 and this value becomes 0, the drive device 73 enters the playback state based on the fourth switching means 77d, and by turning on the changeover switch 54 and turning off the recording amplifier 58, the audio Switch the device 59 to the playback state. As the tape continues to play and the third control signal 82 is received again, the fifth switching means 77e turns on the changeover switch 54 and turns on the recording amplifier 58 to turn on the audio device 69. Recording is fundamental, and even in the configuration of the present invention, learning a unit begins by recording one's own utterances in accordance with the teaching practice audio 83, so when one unit is finished learning, the next unit cannot be started. It is advisable to have recordings in place when starting to study. By doing this, there is no need to make unnecessary operations or comforts for the learners, and apart from that, it is extremely convenient when making adjacent learning units related to each other or creating continuity. good. Note that when switching from the playback state to the recording state, the drive device 73 does not need to be operated because it operates in the same way in either the playback or recording state.

Also, when the learner self-evaluates, the learner can press the progress switch 6
2b causes the microprocessor 60 to activate the drive device 73.
is switched from the stop state to the playback state, and the drive of the magnetic tape 49 is started. By simultaneously turning off the selector switch 54 and turning on the recording amplifier 58, the audio device 5
9 to the recording state and proceed to study 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.

The above has been an explanation of FIG. 6 and the operations related to FIG. 6. Next, the processing procedure centered on the operation of the microprocessor will be explained using flowcharts.

FIG. 7 is a main flowchart of the processing procedure centered on the operation of the microprocessor in this embodiment. In the explanation of the flowchart, each unit of processing will be called a step. FIG. 7 shows the start of the process in step 101, and in this embodiment, this process is started when the power is turned on. Step 102 is a process for setting the logic of the terminals of the microprocessor to the initial state, setting the value of the counter to OK, 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 by detecting the magnetic tape 49.
9 is attached/detached, a flag (in this explanation, it refers to a 1-bit memory indicating a certain state) is set to O or 1.

A flowchart 1 of this step 1o3 (magnetic tape detection) is shown in FIG.

In step 104, the on/off state of the switch is inputted from the terminal of the microprocessor 60 after the chattering occurring at the contact portion of the switch is removed by the input processing of the operation switch 62.

In step 105t/'i, it is determined whether a switch has been turned on based on the data input in step 104, and if the switch has been turned on, the process branches to step 106 of operation switch input processing.

In step 107, it is determined whether or not audio control is necessary, and if necessary, the process branches to step 10B. The flowchart of this step 108 is
The result will be as shown in Figure 0. Step 109 is the driving device 73
It is determined whether or not the dividing section J is necessary, and if necessary, the process branches to step 110.

Step 111 determines whether the selector switch (29 in FIG. 4) is in the "MICOM" position. In other words, it is a decision as to whether or not it is program learning. If the position is "MICOM", the process branches to step 212 and subsequent steps, and if the position is other than "MICOM", the process returns to step 103 and repeats the steps above.

Step 112 is a part for determining whether there is a display instruction, and if there is a display instruction, the process branches to step 113 for display. Note that this instruction is made using the flag mentioned earlier. Step 114 checks whether the tape counter is in operation, and if it is, the process branches to step 115 to count pulses. Step 11
Step 6 checks whether the tape counter is decrementing, that is, rewinding in program learning, and if so,
The process branches to step 117, and if the value of the tape counter is O, the drive device 3 is switched to playback mode.

At step 11B, it is determined whether or not the reception of the control signal has been completed. If it is, the process branches to step 119 and proceeds to a predetermined operation. Once these are completed, step 1
11, the selector switch 29 is in the “'MI” position.
Step 103 as in other cases
Return to

FIG. 9(a) is a flowchart depicting step 115 (pulse counting) in FIG. 7 in detail. Step 128 checks whether there is a pulse sent from the reel table rotation pulse generator 67, and if so, branches to steps 129 and 131. Depending on whether the tape counter command is addition or subtraction, in the former case, the process goes to step 130. In the case of subtraction, the process branches to step 132, and for N, +1 or 1d-
Power one of 1. Step 133iIi It is checked whether the first tape counter is in operation, and if it is in operation, the process branches to step 134 and the aforementioned N is added. Further, steps 135 and 136 relate to the second tape counter, and the operations are the same as those of steps 133 and 134.

FIG. 9(b) depicts step 117 in FIG. 7 in detail. Steps 141 and 144 check whether the tape counter in operation is the first one or the second one. If it is the second tape counter, the process branches to step 142. If the value of this counter becomes O, playback starts. Switching is performed so that

Also, if it is the first tape counter, the process branches to step 146, and when the value of this counter reaches 0, the playback operation is switched. FIG. 11 is a flowchart depicting the display step 113 in FIG. 7 in detail. It is. In FIG. 11, if there is a display request in step 166t/'i, it is determined whether or not there is a proficiency display request, the data stored in the memory, for example, the progress switch at the time of self-evaluation (6 in FIG.
This is a step in which the number of times 2b) was pressed and the number of times the review switch (62C in FIG. 5) was pressed are memorized, and the ratio of the number of times the button was pressed to the number of times a plurality of switches were 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 or not it is a self-evaluation display operation, and continuing the blinking operation during the display operation. Steps 171 and 172 are steps for displaying the unit number if there is one.

FIG. 12 is a flowchart depicting step 119 of the learning control in FIG. 7 in detail. Therefore, in step 216, the drive device 73 (FIG. 5) is switched to the rewind operation, and in step 218, LL is increased by 1. Also, when LL=3, program learning switching (
(corresponding to the third switching means in FIG. 5), the drive device 73 (FIG. 5) is stopped in step 220,
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=6, the program learning is also switched (corresponding to the fifth switching means in FIG. 5), so the audio device 69 (FIG. 5) is switched to the recording state in step 223.

In the above explanation, the magnetic tape has been described as a sumo wrestler's tape, but the present invention is not limited to whether or not the magnetic tape is in a magazine. Although the description has been made using LEDs for various displays, the present invention does not limit the parts used for display in any way, and can be realized using other display materials such as liquid crystal displays or printed materials. Furthermore, although the embodiments have been mainly explained using a microprocessor, 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.

Effects of the Invention The present invention provides a tenth control signal located at the beginning of each learning unit;
A second control signal located in the learning unit and located at a division part of the learning content, and a third control signal located at the end of the learning unit and containing information for controlling the magnetic recording and reproducing device are recorded. a magnetic tape, a pulse generator that generates pulses in accordance with the driving of the magnetic tape, and
a first tape counter that detects the control signal of the control signal and accumulates the number of pulses, and switches to subtraction when an external operation switch is turned on; a second tape counter that accumulates and switches to subtraction when receiving the third control signal; a first switching device that switches to magnetic tape rewinding operation when receiving the third control signal; a second switching device that switches to a first playback operation when the second tape counter reaches an initial value during a magnetic tape rewind operation; and a second switching device that receives the third control signal during this playback operation. If the external operation switch is turned on during this stop, there is a third switching device that activates the device that displays the stop operation and prompts the learner to operate the external operation switch, and if the external operation switch is turned on during this stop, the magnetic tape winding and a fourth switching device that performs a return operation and switches to a second playback operation when the first tape counter reaches an initial value.
By associating the detection of the flilJ control signal with the pulse count obtained by driving the magnetic tape, it is possible to configure a program learning that allows for appropriate review, and it is possible to improve the efficiency of LL learning and achieve reliable operation control. . Furthermore, if the control signals recorded on the magnetic tape have the same frequency and the continuous time, that is, the length of the signal, is differentiated, a device with a simplified configuration for detecting the control signal can be created. This is something that can be provided.
