Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording and reproducing apparatus that temporarily stops the tape running operation of a tape recorder using information recorded on the running tape itself.

There is a deep-rooted enthusiasm for language learning in Japan in recent years. As teaching materials for this purpose, various cassette tapes, texts, and equipment to utilize them,
For example, tape recorders for LL are commercially available. These methods include practice using only audio information, or practice using audio and books. However, when using books, it is extremely difficult to find and read only the necessary parts at the necessary timing.
Moreover, sufficient effects cannot necessarily be expected from audio information alone.

Recently, cassette tape recorders, monitor televisions,
Systems are being developed that use microprocessors (hereinafter abbreviated as MPU), memory, etc. to display the necessary content in addition to voice and text at the necessary timing. In this system, as in the case of LL, the pause time is stored on the tape, so recording efficiency is poor. Also, since the pause time is uniquely determined, even if you want to skip, you have to wait for the pause time. Hereinafter, the problems of the above-mentioned conventional technology will be explained in detail with reference to the drawings.

When the cassette tape is put into playback mode, the teacher's voice on one channel (referred to as the R channel) recorded in audio information record 1 in Figure 1 is played back.
The speaker 12 makes a sound. Subsequently, the text information recorded in the text information recording unit 2 related to the audio information is displayed on the screen of the monitor television 17. The character display will be described in more detail below. The reproduced character information is input to the cassette interface 11 from the terminal on the L channel side,
The MPU 7 converts it into a readable digital signal and sends it to the data bus 18. Address switching circuit 1
3 is the address from MPU7 and the synchronization generation circuit 1
Among the outputs from 4, when the character code from the data bus 18 is desired to be written into the display RAM 15, the former is switched, and when the character code is desired to be displayed on the monitor television 17, the latter is switched. In the case of display, the character code of the display RAM 15 is read out according to the output from the synchronization generation circuit 14, the character code of the character generator 16 is selected according to the information, and the address of the display RAM 15 is displayed on the screen of the monitor television 17. displayed in the position corresponding to Further, in FIG. 2, the data RAM 8 serves as a working address when the system program stored in the ROM 9 is executed.

In this system, as shown in Figure 1, the period of audio information blank section 3 on the cassette tape is the time for the learner to repeat or check the displayed characters, and this period is used for language practice. is extremely important. However, during that period, the tape advances without giving any information, and the teacher's voice is re-voiced again in the next audio information recording section 1', and text information is read at the same time. This is repeated below.

Using this device, text information related to audio information can be displayed for any predetermined time. However, there are three drawbacks as follows.

(1) The period in which the cassette tape continues without giving any information is the period in which it is giving information.
There are three times as many of them, and there is a lot of wasted recording tape.

(2) Even if the learner does not need the repetition time or text display after the audio information, he or she must wait without doing anything until the next audio information appears.

(3) It is not possible to set the repetition time and character display time according to each learner's level.

SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic recording and reproducing device that can eliminate the above-mentioned three drawbacks, improve the recording efficiency of audio tapes, and significantly improve the learning efficiency of learners.

To achieve the above purpose, a pause signal and a standard stop (display) time signal are pre-recorded on tape at the end of the text information recording section, and a blank space is left between the next text audio signal or audio information. take only a small amount of When a pause signal is detected during tape playback, the stop (display) time from the tape is calculated and changed using the standard stop (display) time recorded on the tape in advance or the time set using an external manual input device. The running of the tape is stopped for the specified stop time, and characters are displayed during that time. Furthermore, if the learner wants to proceed to the next audio information immediately after completing one piece of audio information, the learner can cancel the stop state midway.

Hereinafter, the present invention will be explained using FIGS. 3 to 4.

FIG. 3 is a conceptual diagram of the tape surface of a recording magnetic tape, where 20 is an audio information recording section, 21 is a character information recording section, 22 is a section where a pause signal is recorded, and 23 is a tape surface conceptual diagram of a recording magnetic tape.
is a blank space. The difference between FIG. 3 and FIG. 1 is that the pause blank time has been largely eliminated and the recording density has been improved.

FIG. 4 is a block diagram showing one embodiment of the present invention. Blocks that are the same as in FIG. 2 are designated by the same numbers. In FIG. 4, 24 is a skip switch, 24 is a relay circuit, and 26 is a rotary switch.

Hereinafter, the system operation of the present invention will be explained in detail using FIGS. 3 and 4. As shown in FIG. 3, when a recording tape with voice and text information recorded thereon is set in the tape recorder 10 and put into playback mode, the voice information recording section 20 outputs the recorded voice, for example, sentences in a foreign language, from the speaker 12. be done. At the same time, the character information recorded in the character information recording section 21 is converted by the cassette interface 11 into information readable by the MPU 7, and is stored in the display RAM 15 via the data bus 18. On the other hand, the pause signal 22 recorded at the end of the character information recording section 21 is a predetermined digital code, and is also used as the end signal of the character information. When the MPU 7 detects this pause signal 22, it sends an "off signal" to the relay circuit 25 to stop the rotation of the motor of the tape recorder 10 according to the system program recorded in the ROM 9. When the relay circuit 25 receives the "off signal", it turns off the remote terminal of the tape recorder 10 and stops running the tape. After the repetition time _TA , the MPU 7 reads out the character codes stored in the display RAM 15 in the order of the addresses created by the synchronization generation circuit 14, generates characters in the character generator 16, converts them into video signals, and displays them on the monitor television 17.
Enter. Horizontal and vertical synchronization signals to the monitor television 17 are generated by a synchronization generation circuit 14, so that the character display position corresponds to the address of the display RAM 15. Here, address switching circuit 1
3 is RAM for displaying character information codes from the cassette.
15, it is connected to the address bus 19 from the MPU 7. Further, when reading data from the display RAM 15 for display, the address line is switched to the address line from the read address generation circuit 14. Here, after displaying for a display time T _B obtained by a method described later, the MPU 7 sends a "release signal" to the relay circuit 25. Upon receiving this signal, the relay circuit 25
0 remote terminal is turned on, the tape is run again, and the tape recorder 10 records the next audio information,
Play digital information.

The above explanation is for the case where the skip switch 24 is not used at all. If the learner does not wish to display the repetition time or text, he or she may press the skip switch, and the MPU 7 will detect this and immediately give a "cancellation signal" to the relay circuit 25, causing the tape recorder 10 to immediately reproduce the next information.

In FIG. 3, a blank area 23 is a blank area necessary to enter the next information after the motor changes from an off state to an on state and starts rotating at a constant speed. The required period is τ ₁ +τ 2, which is the sum of the time τ ₁ required for the rotation speed to turn on and stop completely, and the time τ ₂ required for the rotation speed to become constant from the _OFF state to the ON state. Further, the repetition time T _A and the character display time T _B are set by a rotary switch 26 so that the learner can select them in advance from several levels according to his or her ability and preference. The repetition time T _A and the character display time T' _B , which are considered to be the most standard, are recorded on the recording tape together with the character information. Here, when the rotary switch 26 is set to a certain contact point, the MPU 7 judges which contact point it is, multiplies the standard times T' _A and T' _B by a certain constant determined thereby, and calculates T _A and T _B. It is written to a specific address in tape RAM 9 as . The MPU 7 refers to the value written in the specific address and stops the motor or displays the value in accordance with the system program.

In the above explanation, only one rotary switch 26 is used for time selection, but for T _A ,
It will be more effective if a separate rotary switch is provided for T _B. In addition, the rotary switch 2
6 is a digital switch, keyboard, or
It is easy to understand that the A/D converter can be replaced with a variable resistor. In addition, Figure 5
Programs recorded in ROM8, i.e. MPU7
2 is a schematic flowchart of the operating procedure of FIG. The character display time is not set in advance, but the display continues until the learner presses the skip switch 24, which also eliminates the block for determining whether the time T _B has elapsed in the schematic flow chart of Figure 5. It is possible to achieve this only by

As explained above, according to the present invention, it is possible to record even if the length of the tape is the same compared to the conventional technology. The amount of information is doubled or tripled, the recording density is improved, and it is efficient and economical. In addition, even if the learner does not need audio information, there is no need to wait for the next audio information to come out, and in addition, the repetition time and character display time can be set according to each learner's ability. This is a new feature that improves learning efficiency and allows users to select the display time according to their ability.
