A bandpass filter 10, an amplifier 12 for amplifying the output of the bandpass filter 10, and a comparator for outputting a result of comparing the output of the amplifier 12 with a reference voltage ( 14), an input device having first, second, third switches and inputs 24 for inputting user commands and data, a ROM 16 in which a predetermined program is stored, and storing data. A writable EEPROM 22 and an output of the comparator 14 according to a program stored in the ROM 16 to be output as a text signal and to control data input and output of the EEPROM 22; 3 Respond to user commands entered from the switch A central processing unit 20 for performing a function according to a program stored in the ROM 16, a RAM 18 for temporarily storing data processed by the central processing unit 20, and a display unit for displaying characters And a second input terminal for reproducing the signal reproduced from the drive unit 26 for driving the display unit 28 according to the signal output from the central processing unit 20 and the right track of the caption audio tape on which the audio signal is recorded. And an output terminal REO for input and output through (R). In addition, although not shown in FIG. 1, power output from a power supply unit (not shown) is supplied to each component that requires power.

Next, the operation of the character information display apparatus for the cassette player according to the embodiment of the present invention configured as described above will be described.

The signal reproduced from the left track of the caption audio tape on which the character information is recorded is input to the bandpass filter 10 for removing noise through the first input terminal L, and then bandpass filtered to the band 1.2-1.4 KHz. The bandpass filtering of the input signal using the bandpass filter 10 is to separate the noise generated when the audio tape is aged or in a bad state from the text signal so that the noise is not input. This is to prevent the signal from flowing back from the amplifier 12 to the first input terminal L.

The output of the band pass filter 10 is amplified by the amplifier 12 and the signal amplified by the amplifier 12 is compared with the reference voltage by the comparator 14 and the result of comparison is applied to the CPU 20. do.

The central processing unit 20 processes the output of the comparing unit 14 according to the program stored in the ROM 16 and outputs it as a text signal.

Perform a function corresponding to the user's command. That is, when the system 20 initializes, the CPU 20 executes a clock program stored in the ROM 16 to output time data to the driving unit 26 to display the current date and time on the display unit 28, and to display the user's text. When a display command is input, the character signal is output to the driver 26 to display the character on the display unit 28. In addition, when a user's text storage and display command is input, the text signal is output to the driver 26 while storing the text signal in the EEPROM 22. In addition, the central processing unit 20 performs a function of storing a phone number, displaying a phone number, displaying a biorhythm, and displaying a world time by executing a predetermined program stored in the ROM 16. On the other hand, the central processing unit 20 is included in the drive unit 26 when outputting the character signal to the drive unit 26 by executing the character reverse display program stored in the ROM (16) when the user's character reverse display command is input; The address of the memory is designated in the reverse order to display all characters displayed on the display unit 28 in reverse order. By using the reverse display function, even when the character information display apparatus for the cassette player according to the present invention is placed upside down, the user can recognize the characters displayed on the display unit 28 by selecting the character reverse display function. Therefore, even if the first switch S1, the second switch S2, and the third switch S3, which are operation switches, are disposed on one side, the user can operate the operation switch using his left or right hand.

RAM 18 is for temporarily storing the data processed by the central processing unit 20, EEPROM 22, which is a nonvolatile memory, predetermined data, that is, character information processed by the central processing unit 20, Since the data is not lost even when the power supply is interrupted, the user stores the character information in the EEPROM 22 and then turns the power on at any time even if the power is turned off. You can see the saved text information. In addition, a signal reproduced from the right track of the caption audio tape on which the audio signal is recorded is output to the output terminal REO through the second input terminal R, and is displayed on the display unit 28 when a user's character information display command is input. The displayed characters are output in synchronization with the audio signal output from the output terminal REO.
