The basic function execution key is the tape rewind key (R
EW key) lla, play key (PLA
Y key) 1101 Tape fast forward key (FF
key)lid, a skip key (SKIP key 1ife) for skipping one song, and an eject key (EJECT key) 11f for ejecting the tape.Five keys 12a to 12e are provided as function changeable keys. They are labeled F1 to F5, respectively.

In addition, the keys used when assigning new functions to the function changeable keys 12a to 12e include the function change enable key (M
EMO key) 13a, a state wait designation key (WAIT key) 13b that indicates waiting until the running state (running/stopping), music presence/absence, etc. change, and a key (CLR key) 13C that erases input data. It is provided. Furthermore, as other keys, a power key 14 RXT4 child volume 14b1 balance key 14c are provided.

The operation method according to the present invention will be explained below.

First, a new function, which is a combination of basic functions, is assigned to the function changeable keys 12a to 12e.

It is assumed that the F1 key 12a is assigned a ``rewind eject'' function that causes the cassette to be ejected after tape rewinding is completed, and the F2 key is assigned a ``repeat'' function that causes the same song to be played repeatedly.

Then press the MEMO key 13a. This causes the processor 1a to enter a function change state.

Next, the function changeable key F1 to which a new function is assigned
If you press , the microcomputer memorizes the function changeable key name.

Thereafter, the user divides the "rewind-eject" function into basic functions according to the operation sequence, and inputs them using the basic function execution keys 11a' to 11llf and the state wait designation key 13b corresponding to the basic function. In addition, condition B
Holding is considered a basic function.

Now, "Rewind-Nizhiev h J 01 n 1.
It consists of three basic functions: rewind operation → wait for rewind completion (wait for state change from running to stop) → eject operation, so the user presses the REW keys 11 a-hWA in the order of keys G corresponding to the basic functions. I.T.
The user presses the keys 13b-4EJECT key 11f, and finally operates the rMEMo key 13a to finish assigning the function to the function changeable key F1. As a result of the above, the processor 1a uses the keys/keys of the RAM 1c.
Register F1 key 2 Rewind → When status changes → Eject in the function correspondence table KFT.

After that, the new function "repeat" is similarly registered in the function changeable key F2. That is, the MEMO key 13a is pressed to enter the function change state, and then the function changeable key F2 is pressed to assign a new function. Thereafter, the user inputs the [repeat ja'>8% function divided into basic functions according to the operation sequence. Now, the "repeat" function consists of two basic functions: 1. Waiting for the end of the performance of the current song (waiting for the state to change from sound to no sound) - Playback operation after skipping in the rewinding direction. In addition, song 1
In order to skip a song, it is assumed that the direction must be operated after the 5KIP key is operated.

From the above, the user presses the keys corresponding to the basic function in order: WA T T key → 5KIP key → REW key, and finally operates the rMEMo key 13a to finish assigning the function to the function changeable key F2. . As described above, the processor 1a registers F2 key: Wait for state change, skip in the rewind direction in the key/function correspondence table KFT of the RAM 1c.

Thereafter, similarly assign predetermined functions to other function changeable keys F3 to F5 as necessary.

With the predetermined functions assigned to the function changeable keys as described above, when the F1 key, for example, is pressed, the processor 1a reads the F1 key from the correspondence table KFT in the RAM 1c.
The function of the 1 key "rewind - wait for state change - eject" is read and control is performed according to the function. That is, processor 1
a causes the tape running drive unit to rewind the tape at high speed, and when a cheap running stop signal is generated from the sensor (
(state change), load/unload the cassette using the loading/unloading motion.

Also, if the F2 key is pressed during performance, the processor 1a
reads the F2 key function “wait for status change, skip one rewind direction” from the correspondence table KFT in RAM1c, and presses v
i41! control is performed according to the performance. That is, when the performance of the current song is finished and no sound is produced, the song interval detection circuit 'RI2 generates the song interval signal Mis (state change). As a result, the processor la causes the tape drive unit to immediately rewind the tape in the rewinding direction so that the song interval is detected.
Start playback (repeat).

<Effects of the Invention> According to the present invention, a basic function execution key, a function changeable key that can change the function to be performed by the audio equipment, and a function change enable key are provided, and in the function assignment state, the function changeable key The new function to be assigned to the function is specified using the basic function execution key, and when the function changeable key is operated, the audio equipment is configured to execute the assigned new function. There is no need to prepare a separate piece of audio equipment, and users can freely assign their favorite functions to the keys to operate the audio equipment.
