Abstract

PURPOSE:To use the titled player easily, by providing the player with a display part of musical performance time recorded in a disc and a disply part of music indication of a program inputted from a keyboard and lighting up these dispaly parts in every change of the contents of a program during the performance. CONSTITUTION:Various information from a disc is displayed by a bar dispaly 703 of a time position corresponding to the contents of the program in addition to an integrating time disply 701 from the leading digit of the disc, the leading position display 702 of each music, music No. display 704, and min/sec display 705. In every time when the change of the contents of program performance is inputted by a program key, display parts 704, 705 dispalying performance time display the music, min. and sec. specified by a command outputted by the key input and the display bar 703 corresponding to the addition and erase of musics is turned on and off. Consequently, the change of the program in performance is easily displayed.

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 loaded on the turntable, the beginning position of the famous song read from the disc is displayed on the display. Thereafter, a program key for program performance is accepted, and when the user presses the PLAY key after inputting two arbitrary song numbers, the program play begins and the songs are played in the order specified. Then, by pressing the 5TOP key, the program performance is canceled and stopped.

However, with this arrangement, it is not possible to make changes such as adding or deleting programs while the music is being played; any changes can only be made after deleting the entire program by pressing the STOP key. This made it very inconvenient and difficult 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 Fig. 2, 1 is a turntable, 2 is a turntable drive motor, 3 is an optical pickup, 4 is a digital signal processing circuit, 6 is a microcomputer circuit for system control and display, 6 is a keyboard, and 7 is a display. It is.

In the above configuration, when a disc is mounted on the turntable 1, the motor 2 rotates, and the optical pickup 3 collects digital signal music information, position information for each episode, song number information, elapsed performance time information, etc. The position information is sent to the digital signal processing circuit 4, where each signal is processed, and each information other than music information is input to the microcomputer circuit 5. Based on these various pieces of information, the microcomputer 6 data 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 for each time, a track number display 704, and a minute/second display 706. . Then, along with the above display, key commands from the keyboard 6 are accepted, and the program key 602
Displays the number of songs, minutes, and seconds specified in 704 and 7.
05 is shared and displayed, along with a bar display 703 at the time position corresponding to the program content.

Then, input any song using the program key 602, and press
Press the LAY key to begin program play. Note that if the PLAY key is pressed without pressing the program key 602, normal manual performance is performed.

Here, when the program key 602 is pressed during performance,
When manual performance is in progress, it becomes a program performance, and the display sections 704 and 705 that previously displayed the performance time are changed to show the song, minutes, and seconds by manual key commands, and accept input for specifying any song. . and the Ent key or P
Add songs by operating the LAY key, 5TOP, CLEAR
The song is erased by key operation, the display bar 703 at the corresponding position lights up or goes out, the display section 7o4.706 is changed again to display the performance time recorded on the disk, and the program performance continues.

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

In the above embodiment, the displays 704 and 705 constitute the first display section □, and the displays 701 and 702.

03 constitutes the 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 displaying the program changes in an easy-to-understand manner even during the performance, providing an extremely user-friendly digital audio player. be able to.

Claims (1)

[Claims] The same first display section that selectively displays the performance time recorded on the disk and the number of songs, minutes, and seconds input using the program key, and the number of songs, minutes, and seconds input using the program key. and a second display section that lights up and displays a position corresponding to the change input, and each time there is a change input to the program performance content using the program key during performance, the second display section lights up a position corresponding to the change input. An optical digital audio player characterized in that program performance is performed by displaying a lighted display indicating addition and deletion.
