After processing in I (16), ROM II (17), and ROM III (18), the display driver 15 is applied with an address signal to display the selected characters in the display unit 9.

In this invention of such a configuration, first, a description will be made of a conventional cassette tape player according to FIG.

In the tape used in FIG. 1, as in FIG. 4, the audio signal is recorded in one channel, and text information corresponding to the audio signal is recorded in the other channel.

Therefore, the signal picked up by the head A of FIG. 1 becomes a voice signal and the signal picked up by the head D becomes character information.

The audio signal picked up by the head A is amplified by the preamplifier 1 and volume-adjusted by the variable resistor 2 and then output to the speaker 4 through the power amplifier 3 and picked up by the head D. The text information is amplified by the preamplifier 5 and then applied to the waveform shaping circuit 6 so that the analog signal is converted into a digital signal and then applied to the microcomputer 7 so that the microcomputer 7 processes the display information. A text signal is sent out to the display unit 9 which is displayed on the display unit 9.

Therefore, the user can hear the voice signal output to the speaker 4 and can see the character corresponding to the voice signal displayed on the display unit 9 so that one sentence can be seen on the display unit 9 and at the same time the speaker ( 4) It can be used effectively when learning a foreign language.

However, in the conventional method, since only voice signals and text information of one foreign language are recorded on the tape, another tape was required for education of another foreign language.

In view of the above, the present invention records two or more audio signals on a tape as well as records text information at the same time as in FIG. 3, so that various foreign languages can be learned using one tape.

This will be described based on FIG. 2, FIG. 5, FIG. 7 or FIG.

First, the user selects one audio signal from the audio signals recorded on the tape by using the switches SW1, SW2, and SW3 of the switch block 11.

When one voice signal is selected by the switches SW1, SW2, and SW3 of the switch block 11, the microcomputer 7 recognizes the voice signal and transmits the control signal S to the line selector 10 and the display controller 8. ₀ ), (S ₁ ) will be supplied.

That is, it is determined whether any of the switches SW1, SW2, and SW3 is 'on', and according to the 'ON' state of the switches SW1, SW2, and SW3, different control signals S _{0 are} determined. , (S ₁ ) will be printed.

In the line selector 10, as shown in FIG. 5, only one signal line outputs a high level to the inverters I ₁ , I ₂ , and I ₃ according to the control signals S ₀ and S ₁ . The rest of the outputs are low-level to 'turn off' only one of the transistors Q1, Q2, and Q3 so that only one of the audio signals picked up from the heads A, B, and C is preamplified. Is applied to 1).

For example, when the switch SW1 is 'on', the microcomputer 7 outputs the control signals S ₀ and S ₁ as logic signals as '0 and 1', and the decoder 12 controls the above-described control signals ( By recognizing S ₀ ) and (S ₁ ), the high level is output to the inverter I1 and the low level is output to the inverters I ₂ and I ₃ so that only the transistor Q1 is 'turned off' so that the head A Only the audio signal picked up from) is applied to the preamplifier 1, and when the switch SW2 is turned on, the microcomputer 7 sets the control signals S ₀ and S ₁ to the logic signals of '0, 1'. The decoder 12 recognizes the control signals S ₀ and S ₁ and outputs a high level to the inverter I ₂ , and outputs a low level to the inverters I ₁ and I ₃ . Therefore, only the transistor Q2 is 'turned off' so that only the audio signal picked up from the head B is applied to the preamplifier 1, and when the switch SW3 is 'on', the control signal S _{0 at} the microcomputer 7 is turned on. , (S ₁ ) is the logic of '1, 1' Signal, and the decoder 12 recognizes the control signals S ₀ and S ₁ described above, and outputs a high level to the inverter I ₃ , and sets the bell to the inverter I ₁ and I ₂ . By outputting only the transistor Q3 is 'turned off' so that only the audio signal picked up by the head C is applied to the preamplifier 1.

That is, as one voice signal is selected in the switch block 11, the microcomputer 7 outputs different control signals S ₀ and S ₁ , and the control signals S ₀ and S ₁ . Therefore, the line selector 10 selects one of the audio signals picked up from the heads A, B, and C and applies the preselected signal to the preamplifier 1.

Since the voice signal applied to the preamplifier 1 is volume-controlled by the variable resistor 2 and then outputted to the speaker 4 through the power amplifier 3, the user finally has two or more voice signals recorded on the tape. One voice signal can be selected and listened to.

On the other hand, the character information picked up by the head D is amplified by the preamplifier 5, and the analog signal is converted into a digital signal through the waveform shaping circuit 6 composed of the diode D1 and the condenser C1. ) Is applied.

At this time, in the data format recorded on the tape, character information of three audio signals is recorded as shown in FIG. 10, and control data in which each character information is recorded in front of each character information is recorded.

Therefore, the microcomputer 7 converts the serial data converted into digital signals through the waveform shaping circuit 6 into parallel data and stores the respective character information and control information.

The microcomputer (7) in the switch (SW1), (SW2), (SW3), the control signal according to the selected state (S _0), since thereby outputs (S ₁₎ and the control signal (S ₀₎ of the switch block 11 , (S ₁ ) is decoded by the decoder 13, and the output of the decoder 13 is a ROM in which character information corresponding to each language is recorded through the inverters I ₄ , I ₅ , and I ₆ . The operation of I (16), ROM II (17), and ROM III (18) is selected.

That is, the ROM I (16), the ROM II (17), and the ROM III (18) are selectively driven in accordance with the switching selection in the switch block 11.

In this way, when one of the ROM I (16), the ROM II (17), and the ROM III (18) is driven by the voice signal selection, and the character information and control information read from the head D are stored, the microcomputer 7 records the information. The character information is output to the ROM driven by the terminal ADD2. The driven ROM receives the character information and processes the character information into the font font information and applies it to the microcomputer 7 through the terminal DATA2.

The microcomputer 7 outputs the character font information applied from the terminal DATA2 to the terminal DATA1, and outputs an address to the terminal ADD1, which is processed by the display driver 15 and displayed on the display unit 9. To be.

Accordingly, the display unit 9 displays a character corresponding to the selected voice information.

Therefore, in the present invention, the tape corresponding to two or more voice signals and text information can be reproduced to display a character corresponding to a desired voice signal and voice signal, so that a plurality of foreign languages can be learned using a single tape.

As shown in FIG. 9, the flowchart for the microcomputer 7 in which one voice signal and text information is reproduced is checked by checking the switch connection state of the switch block 11 to control signal S ₀ . Outputs (S ₁ ), saves the switch state to RAM, and converts the character signal input to the terminal (IN) from serial data to parallel data to store character information and control information.

After checking whether the switch input corresponds to the stored control information, the stored character information is output to the terminal ADD2, the font information of the character is read out to the terminal DATA2, and the address is output to the terminal ADD1. DATA1) outputs the font information of the characters so that the display driver 15 displays the selected character information on the display unit 9.

As described above, the present invention records a plurality of voice information and text information on a tape, and then reproduces text information corresponding to a desired voice signal and a voice signal according to a user's selection. It is effective to learn many foreign languages using a single tape without having to purchase a ticket.
