Abstract

PURPOSE:To confirm easily programmed contents, by lighting the bar dispalys of the programmed music number and leading position in every keying of an optional music from a keyboard. CONSTITUTION:When a disc is charged in a turntable 1, the leading positions of respective musics are displayed on a bar 702 in accordance with music position information, playing time information, etc. The integrating time from the initial position of the disc is also dispalyed on a bar 701. If a required music is received at the performance of the program, the programmed music number and minute position are illuminated. In every completion of the performance of the program, the dispaly bar is turned off. Thus the programmed contents can be easily confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical digital audio player, and in particular, to an optical digital audio player in which music selection positions, etc., are easily understood (displayed).

On digital audio discs, along with the music (songs), the position information of each picture, 9 song number information, elapsed performance time information, etc. are recorded. When playing a program, it is possible to display the selected song position on the same or different display.

Conventionally, when performing a program on such a digital audio disc, the display has been performed according to the procedure shown in the flowchart of FIG.

That is, when the disc is mounted on the turntable and started, the bar-shaped display elements of the display device that correspond to the beginning of each city are lit in sequence to display the beginning position of each city, and the same or another indicator.”
- The cumulative time from the initial position of the disc is displayed digitally, and then the desired song is programmed by manually pressing the keys. Then, it is determined whether the PLAY key is turned on, and when the PLAY key is turned on (that is, when disc playback is commanded), the start position of each city programmed in advance at that time is displayed all at once on the display. A bar is displayed, and then the songs are played in the programmed order.

However, with such display devices, when programming a disc with a large number of songs, including dozens of songs, it may become unclear whether the input is correct while keying in, or the number of songs recorded on the disc may become unclear. There was a drawback that you would not know if you accidentally selected the second song.Also, the bar that was displayed does not disappear even after the performance is finished, so it is difficult to know how many programmed songs remain. There was also the inconvenience of not knowing if they were there.

In order to solve the drawbacks and inconveniences mentioned above, the present invention enables programming by lighting up the bar indicating the number and position of the block-recorded song each time a key indicating completion of song selection for each city to be block-recorded is pressed. The present invention provides an optical digital audio player that displays the state of the playback in an easy-to-understand manner.

FIG. 2 shows an embodiment of an optical digital audio disc player according to the present invention.

In Fig. 2, 1 is a turntable, 2 is a turntable drive motor, 3 is an optical pickup, a 4-digit digital signal processing circuit, 6 is a system control microcomputer circuit, 6 is a keyboard, and 7 is a display. .

In the above configuration, when a disc is mounted on the turntable 1, the pickup 3 moves in the radial direction of the disc 10, and the first three positions of each city are located at the bar 702 according to the song position information, performance time information, etc. recorded in the disc 1. At the same time, the cumulative time from the initial position of the disc 1 is displayed on a bar 701 based on the position information of the pickup 3. )<-702, the microcomputer circuit 6 accepts commands for each key on the keyboard.

At this point, when performing a program performance, add the arbitrary track number, minute, and second data keyed in with each key from 1st to 1st time and the 1st key, and press the Rero I key. When this happens, the bar 703 displays the programmed track number and minute position and an error display, and the music is played in the programmed order. For example, if you want to play the 1st, 4th, and 6th songs starting from 1 minute 10 seconds, press each key on the keyboard 6 to select the country 0 section, same, ■ decoy, same, field, country, field もcountry, times. When pressing tW, t=aim, the corresponding bars of the bar 703 light up each time each position of the first part of the first, fourth, and sixth songs is keyed in. Therefore, when programming, it is possible to check whether the input has been entered correctly each time the key is pressed, and since the program can be performed in correspondence with the bar display at the beginning of each city on the bar 702, the data can be recorded on the disk. You won't accidentally select more songs than you already have.

Furthermore, in this embodiment, when a block-recorded song ends, the iff/~- of the finished song disappears one by one. Like this 1. You can see at a glance how many blocked songs remain, making it extremely convenient.

FIG. 3 shows a flowchart of the above operation, and if the block diagram of the microcomputer circuit 6 is assembled according to the flowchart of FIG. 3, the above display function can be easily realized.

In addition, if you want to play the programmed song repeatedly, after all programs have been played, the contents of all programs may be displayed again on the bar 703, and the operations described above may be repeated. This display can also be easily realized using the block diagram of the microcomputer circuit 6.

As described above, according to the present invention, each time a desired song is keyed in on the keyboard, the beginning position of the song is displayed on the display, making programming extremely easy to understand. In addition, the display bar turns off each time the program finishes playing, so you can clearly see the number and number of songs remaining in the program, which is very convenient.
