Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a programmable optical digital audio player.

FIG. 1 shows an operation flowchart of a conventional optical digital audio player, and an overview of the operation will be explained.

When the disc is attached to the turntable, the beginning position of each song read from the disc is displayed on the display. After that, a program key for program play is accepted, and when you press the PLAY key after inputting the desired song number and number of songs, the program play starts and the songs are played in the order specified. Then, by pressing the STOP key, the program performance is canceled and stopped.

However, if you do this, you will not be able to add or delete programs or make other changes while playing, and you will always have to STOP.
Changes cannot be made until the entire program is erased by pressing the key. This made it extremely inconvenient and inconvenient to use.

SUMMARY OF THE INVENTION An object of the present invention is to provide an optical digital audio player that is extremely easy to use and allows program changes to be input even during playback.

An embodiment of the optical digital audio player of the present invention is shown in FIG. In Figure 2, 1
2 is a turntable, 2 is a turntable drive motor, 3 is an optical pickup, 4 is a digital signal processing circuit, 5 is a microcomputer circuit for system control and display, 6 is a keyboard, and 7 is a display.

In the above configuration, when the disc is mounted on the turntable 1, the motor 2 rotates, and the optical pickup 3 receives digital signal music information, position information of each song, song number information, elapsed performance time information, etc. The position information of the pickup 3 is sent to the digital signal processing circuit 4, where each signal is processed, and each information other than the music information is input to the microcomputer circuit 5. Based on these pieces of information, the microcomputer circuit 5 causes the display 7 to display an integrated time display 701 from the initial position of the disc, a start position display 702 of each song, a track number display 704, and a minute/second display 705. Then, along with the above display, key commands from the keyboard 6 are accepted, and the number and number of songs specified by the program key 602 is
Numerical displays 704 and 705 are used to display minutes and seconds, and a bar 703 indicating the time position corresponding to the program content is also displayed.

Then, by inputting an arbitrary song using the program key 602 and pressing the PLAY key, the program performance starts. Please do not press the program key 602.
Press the PLAY key to perform normal manual play.

If the program key 602 is pressed during the performance, the program play will be started if the manual performance is being performed, and the display sections 704 and 705 that were previously displaying the performance time will change to the song according to the key input command.
The display changes to minutes and seconds and accepts input of any song specification. Then, a song is added by operating the Ent key or PLAY key, and a song is deleted by operating the STOP/CLEAR key, the display bar 703 at the corresponding position lights up or goes out, and the display sections 704, 7
05 is again changed to the performance time display recorded on the disk and the program performance is continued.

FIG. 3 shows a flowchart of the operation of FIG. 2, and by programming the microcomputer circuit 5 according to this flowchart, the above-described operation can be easily realized.

Note that in the above embodiment, the displays 704 and 705 constitute the first display section, and the displays 701, 702, and 7
03 constitutes a second display section.

As described above, the present invention uses the same display section to display the performance time recorded on the disk and the song designation of the program performance inputted on the keyboard, and also displays the position corresponding to the program content. Since the light is turned on or off each time there is an input, it is possible to change the program while clearly displaying the program change contents even during the performance, and to provide an extremely user-friendly digital audio player. be able to.
