The control signal is read by the head when the cassette tape is inserted into the mechanism 1, the output signal is amplified by the reproduction amplifier circuit 3, decoded, and separated into the audio signal and the character code signal by the signal processing circuit 4. The character code signal enters the CPU 10 through the input / output circuit 5, and is stored in the RAM 11 and then stored in the RAM 10.
The OM 12 converts the character information into character information corresponding to each character code signal, and the character information is input to the shift register 13 via the CPU 10. If you play the tape here,
Character information on the song being reproduced is displayed on the display 14, and when the scroll button 8 is pressed, the display on the display 14 changes depending on how the scroll button 8 is pressed.

Next, how to press the scroll button 8 and shift of character information will be described with reference to FIGS.

FIG. 5 shows character information stored in the RAM 11. Data 1 to data 21 have a recording unit in the order of song number, title, singer, and topics.
One piece of the data includes information for one music piece. Also,
The capacity of each recording unit is the same for each data.

First, in step 16 of FIG. 6, the mode button 15 of FIG. 2 is pressed to set a mode for displaying information of a character code signal among the signals recorded on the tape. When the tape is played back from the beginning in this state, the character information corresponding to the control signal (data 1 in FIG. 5) for the music being played back is displayed on the display 14 in the order of the music number and title by 12 digits (data 1). (1st to 12th digits of character information corresponding to a in (a) are displayed.) Next, after pressing the scroll button 8 in step 17,
In step 18, it is determined whether or not the number of times the scroll button 8 is pressed for one second is two times. If the scroll button 8 has been pressed twice, the process proceeds to step 19, where the display 14 stops displaying data 1 and displays the first 12 digits of the character information corresponding to e in data 2. If it is determined in step 18 that the scroll button 8 has not been pressed twice, the process proceeds to step 20 while the display on the display 14 remains unchanged, and it is determined whether or not the scroll button 8 has been pressed only once per second. . If the scroll button 8 was pressed only once,
The display is scrolled to the left by one digit to display the second to twelve digits of the character information corresponding to a in data 1. If the scroll button 8 has not been pressed only once, the process proceeds to step 21, where it is determined whether the scroll button 8 has been pressed for one second or more. Here the scroll button 8
Is pressed for more than 1 second, step 23
