Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention provides an improved programming method for program playback functions, such as those provided in a compact disc player, in which the playback order of songs can be arbitrarily set. It is related to.

(Explanation) Conventional technology Conventionally, as a program playback method for a compact disc player, for example, Japanese Patent Laid-Open No. 61-99983 (G1
1B27/10) is publicly available. According to such a program playback method, a program information selection key for specifying a song number is arranged on the front panel, and by pressing the number key corresponding to a desired song number, the song number is stored in the memory in sequence. be done. However, in this case, since the disc usually stores more than a dozen songs, in order to satisfy the program function for any disc, it is necessary to write about 20 number keys on the front panel. This creates space problems on the front panel.

In contrast, current compact disc players
There are some devices that use the skip key to play the beginning of a song as the song number setting key, and by operating the memory key while adding or subtracting the song number with the skip key, the desired song number can be memorized in memory in sequence. ing. In this case, the only buttons to be operated are the two skip keys (for up-down) and the memory key, so there is no space problem on the front panel as described above, but the skip key and memory key can be used alternately. The operation becomes complicated because it has to be performed at the same time.

G'M Problems to be Solved by the Invention The present invention aims to provide a program playback method that does not cause space problems on the front panel and allows easy program operation.

B.) Means for Solving the Problems In view of the above problems, the present invention provides that, when playing a medium in which, in addition to main information, division number information for sequentially dividing the main information from a playback start position is stored, A program playback method for arbitrarily storing section number information in a memory and sequentially playing back divided areas of the medium according to the stored section number information, the method comprising: a number display section; and the contents of the number display section. clock means for incrementing the number, and a memory button, and by operating the memory button when the numeric display section is incrementing and displaying a desired number, the number is sequentially stored in the memory as the division number information. It is characterized by being memorized.

When the one-phrase action program is running, the contents of the numeric display section change over time by stepping. By operating the memory button at the timing when the desired section number is displayed on the numerical display section, the desired section number information is loaded into the memory.

(c) Examples Hereinafter, one embodiment of the present invention will be described using the drawings.

FIG. 1 is a circuit block diagram of this embodiment.

(1) is a mechanism section of the player consisting of a pickup device, a turntable device, etc., (2) is a control microcomputer that controls this mechanism section (1), and (3) is a device that stores playback song numbers. Tame RAM
(4) is a display section controlled by the control microcomputer (2), (5) is a memory button, and (6) is a program button.

During program playback, operate the memory button (5) and program button (6) to sequentially store the song numbers in the program memory (3), and then operate the playback button (not shown) to set the player to playback mode. By doing this, program playback is executed. That is, at this time, the programmed song numbers of the songs to be played are sequentially read out from the program memory (3) by the control microcomputer (2), while the control microcomputer (2) mechanism g
(1) to sequentially bring the pickup to the starting position of a desired song number, and then sequentially perform regeneration of the mortar according to the regeneration program stored in the program memory (3).

Next, we will explain the song program operations executed by operating the memory button (5) and program button (6) according to the flowchart in FIG.

When the program button (6) is operated for the first time, the program operation starts, that is, in step 1, the variable N is
After setting it to 0', N = N+1 is calculated in step 2, and then N-N+1 is displayed on the display (4) in step 3.
The calculated value of 11' is displayed. When the operator wants to program the first song, he/she should press the display (
4) When '1' is displayed, press the memory button (5).
), such song number ``''1'' is stored in the program memory (3).

That is, in step 4 it is determined whether or not the memory button (5) has been pressed, and if YES here, the song number 11' is stored in the program memory (3) in step 5. In step 4, if the memory button (5) is not pressed within 2 seconds after 'h1' is displayed on the display section (4), the determination result is set as No, and the song number 11 is stored in the program memory (3).
The program operation proceeds to the next step without memorizing ``bo.'' In step 6, it is determined whether the variable N is equal to the total number of songs stored on the disk.If it is determined NO here, step 2 Returning to step 6, N=N+1 is executed and the song number ``2'', which is incremented by 1, is displayed on the display section (4).The total number of songs, which is the criterion for determination in step 6, is the number stored on the disk. Table of contents information (T, OoC: Table of contents
e-Of-Contents) is read from the disk prior to program operation.

As described above, the contents of the display section 4 are changed from step 2 to step 6.
If there is a song that you want to program between ``1#'' and the maximum song number on the disc, press the memo IJffi (5) for 2 seconds while that song number is displayed to program the program memory (3 ).For example, the maximum song number is '101' and the song program order is '101'.
→5→8→6→7→4→5, the display part (4
) is displayed as month-'3','8? By pressing the memory button (5) when
3# and J# are stored sequentially.

When the content displayed on the display section (4) matches the maximum song number on the disc, YES is determined in step 6, and in step 7, the program operation is terminated, or the program button (6) is pressed again. It is determined whether the number is nine or not. If the determination result in step 70 is YES, the program operation of the song is of course terminated, but in the above example, only the song numbers 'h1#, %3#, 18' are stored in the program memory.
3) The last song numbers 16', 17', and 1 are not stored in
4' and 15' must be stored in the program memory (3), so the determination in step 7 is No. In this way, if the determination in step 7 is NO, the process returns to step 1 and the variable N is set to 50# again, and hereafter, in step 2
~1 is displayed on the display (4) by the repeat routine of step 6.
The numerical values counted up in order starting from 1# are displayed again.

In the above example, when the song is displayed again, the song number %6#,
%7# is stored in the program memory (3) in response to pressing the memory button (5). Then, when the displayed song number reaches the maximum song number again, the last song number % will be displayed at this timing.
Program button (6) because 4# and 5# are not memorized.
Since the second suppression operation is not confirmed, return to step 1 and display F! again. 15(4), the song numbers '''1' to 110' are displayed, and when the display is %41 and %51, the song number J# is displayed in response to pressing the memory button (5).
%5# is stored in program memory (3).

As described above, the program memory (3) is stored as 1 → 3 → 8.
The desired song numbers are sequentially stored in the order of →6→7→4→5. When all the desired song numbers are memorized, the program button (6) is pressed again.
The re-operation of is confirmed in step 7, and the program operation is ended.

According to this flowchart, since the determination in step 7 is made after the display contents of the display section (4) reach the maximum song number, for example, as in the above example, the song number 5# is stored in the program memory. (3) Even if the program operation is finished, the remaining song numbers 16', 17', 18'
, '9#, and 110' are displayed, so it takes an extra time (2 seconds x 5-10 seconds in this case) until the program operation is completed. Therefore, in order to eliminate this inconvenience, it is actually preferable to set the flowchart so that the program operation is terminated in response to the re-operation of the program button (6). Furthermore, although the display section (4) is shown as an up-count display, it goes without saying that a down-count display may also be used.

(G) Effects of the Invention According to the present invention, when a program is operated, a division number such as a song number is displayed in the numerical display section in increments over time,
Since the memory operation only requires selecting the desired division number 1 and operating the memory button when displaying, the program operation is extremely simple, and since the operation button only needs to be the memory button, the operation button related to the program operation is The installation space can also be reduced.
