Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-disc player for selecting and playing one of a plurality of discs such as CDs and MDs, and more particularly to realizing a new playback mode.

[0002]

2. Description of the Related Art Generally, in the reproduction of a multi-disc player for CDs, MDs and the like, one disc is selected one by one from a plurality of stored discs, and all of the discs are arranged in the order of music for each disc. After the reproduction, the process proceeds to the reproduction of the next disk.

[0005] For example, FIG. 10 is an explanatory diagram showing the order of music to be reproduced in the case of a six-sheet changer which stores six disks and sequentially reproduces them. As shown in FIG. 10, the reproduction is performed simply in the order of the first song to the last song of the disc 1, the first song to the last song of the disc 2, the first song to the last song of the disc 6.

[0004] Generally, disc players include:
A function to select the next disk to be reproduced, a function to sequentially forward or reverse the music to be reproduced next are provided, and the reproduction of one disk is continuously repeated, or the reproduction of one music is performed. Is provided repeatedly. Therefore, the user can select and play a desired song by performing an operation for selecting a disc or a forward or backward operation of a song, and also perform a repeat for a desired disc or a desired song. By performing the operation, only the desired disc can be continuously reproduced, or only the desired music can be repeatedly heard.

[0005] Further, there is a multi-disc player having a random function of randomly reproducing music included in a plurality of discs stored in the player. In this type of player, a disc number and a song number are randomly designated based on a random number generated by a random number generator or the like or recorded in advance as data, and a random song is set over all songs on a plurality of discs. Reproduction is performed in order. In such random reproduction, a large number of songs included in a plurality of discs stored in the player can be reproduced in various song orders. In addition, since the order of the songs cannot be predicted, the interest in the song to be reproduced next can be increased.

On the other hand, for a plurality of discs stored in the player, an arbitrary number of songs within a predetermined range are registered in an arbitrary order, and the registered songs are reproduced sequentially in the order of registration. There are also multi-disc players. When operating a player of this type, the user specifies an arbitrary number of pieces of music by designating the data consisting of the disk number on which the music is recorded and the music number of the music in the disk as the identification of the music. By sequentially registering the identifications of the music pieces, it is possible to construct reproduction music order data in which the identification numbers of a predetermined number of music pieces are sequentially arranged. Alternatively,
There is also a multi-disc player having a function of sequentially playing back in the set playback order by setting the playback order together with the identification of the song instead of playing back in the registration order. In any case, after the reproduction music order data constructed as a music identification column is stored in the storage means, each music is reproduced in the music order based on the reproduction music order data.

[0007]

However, the conventional multi-disc player as described above has the following problems.

First, as shown in FIG. 10, in a system in which a plurality of discs are all sequentially reproduced in a simple manner, when a disk is reproduced only for a shorter time than the reproduction time of all the music on one disc, As a result, only one disc can be reproduced, and a plurality of discs stored in the player cannot be fully utilized. Also, considering the user's feeling of use, it is monotonous to always listen to all the songs on one disc in the same order, and the possibility of losing interest in the disc at an early stage increases.

The major reason why the multi-disc player employs such a method of sequentially reproducing all songs on a plurality of discs is that it takes time to change discs such as CDs. For this reason, the system generalized in the multi-disc player for CD follows the multi-disc player for MD or the multi-disc player corresponding to both MD and CD, and is a standard system. That is the fact.

However, in an MD using a memory for storing music information, the disc can be changed while the stored data is being output. There is no or almost no lost time.
Similarly, with respect to CDs, the adoption of a system having a memory for data storage can eliminate blank time at the time of disc change.

[0011] As described above, the user can select a desired song and reproduce it by performing an operation for selecting a disc and a forward or backward operation of the song. By performing a repeat operation on a desired song or a desired song, only the desired disc can be continuously played back, or only the desired song can be repeatedly heard. However, performing an operation for selecting a disc and an operation of forward / reverse feed of music for each music is extremely troublesome and operability is low. Also, it is monotonous to repeatedly listen to only a desired disc or a desired song.

[0012] Further, when the songs included in a plurality of discs are reproduced at random, the order of the songs cannot be predicted, which can increase the interest in the songs to be reproduced next. Therefore, it is not possible to obtain the same effect as when a certain pattern is given in the order of music to be reproduced. For example, when trying to listen to songs included in a plurality of discs, if there is a pattern in the order of the songs, based on the pattern, the reproduction history of the pattern, the future reproduction schedule, or the current reproduction position, etc. By displaying this information, the user can easily grasp the information on those reproduction patterns. In this case, the user can have a total image of all the songs to be reproduced from the information on such reproduction patterns, and can enjoy the reproduction of the songs more actively in association with such images. . However, in perfect random playback, even if the song to be played next is displayed, the display cannot be given any more meaning, and the user cannot obtain a total image of all the songs to be played. Without having, you'll be completely passive to accept random song playback.

On the other hand, when the user registers the identification of the arbitrary number of songs and constructs the playback song order data including the song identification columns, the user must specify the disc number every time one song is designated. Therefore, there is a problem that it takes time and labor to input a large number of songs, and the operability is low. Further, in order to be able to register a large number of music pieces, a storage means having a large storage capacity is required.

[0014] The above-mentioned problems are caused by a problem with a CD or MD.
Etc., not limited to a multi-disc player mainly for a disc on which audio data is recorded, such as a DVD or LD,
In various multi-disc players targeting various discs, including discs with recorded image data,
Exists as well. That is, in a DVD, LD, or the like, a method of reproducing all reproduction data for each disk is standard, and such a reproduction method is also monotonous.

The present invention has been proposed to solve the above-mentioned problems of the prior art.
When playing multiple discs, providing a patterned playback mode other than the standard all data playback mode for each disc, providing a novel playback mode that is different from existing trick play such as repeat or random It is to provide a possible multi-disc player and its control method.

[0016]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, data is sequentially reproduced over a plurality of disks on the basis of a program number such as a music number. It is possible to realize a patterned reproduction mode other than the standard all data reproduction mode for each disk.

That is, according to the first aspect of the present invention, there is provided a method for controlling a multi-disc player for selecting and reproducing one of a plurality of discs, the program being added to data recorded on the disc. It is characterized by having a reproducing step of sequentially reproducing data over a plurality of disks based on the number. According to this configuration, data associated with a program number can be sequentially reproduced over a plurality of discs, and a new reproduction mode patterned by the program number can be realized.

According to a second aspect of the present invention, in the control method according to the first aspect, the reproducing step includes a step of sequentially reproducing one piece of data corresponding to a single program number over a plurality of disks. Features. According to this configuration, it is possible to realize a new reproduction mode having a pattern of continuously reproducing data of one program number and then reproducing data of another program number continuously.

According to a third aspect of the present invention, in the control method of the second aspect, the reproducing step sequentially selects the program numbers in ascending order or descending order, and sets the program numbers in advance for one program number. Characterized by a step of sequentially reproducing each one of the data associated with the program number in the order of the discs. According to this configuration, after the data of one program number is continuously reproduced, the data is moved up (in ascending order) or down (in descending order) by one.
, A new playback mode having a pattern of continuously playing back the data of the program number is realized. Such ascending or descending order processing is the most basic arithmetic processing, and can be easily realized by a very simple arithmetic circuit. Further, since the respective disks are sequentially reproduced in a preset disk order, data of the same program number can be sequentially reproduced over all disks without having to select the disk order.

According to a fourth aspect of the present invention, in the control method of the second aspect, the reproducing step randomly selects a program number, and selects one program number in a preset disk order. The method is characterized in that the method includes a step of sequentially reproducing one piece of data corresponding to the program number. According to this configuration, it is possible to realize a new reproduction mode having a pattern of continuously reproducing data of one program number and then continuously reproducing data of the next program number selected at random. it can. This pattern is more complicated than selecting the program numbers in ascending order or in ascending order, and the user can enjoy more varied reproduction.
Further, similarly to the third aspect, since the respective disks are sequentially reproduced in a preset disk order, the data of the same program number can be sequentially reproduced over all the disks without having to select the disk order.

According to a fifth aspect of the present invention, in the control method of the third or fourth aspect, the preset disk order includes a first disk order and a second disk order. . Then, the reproducing step includes a step of alternately repeating the reproduction in the first and second disc order for each program number. According to this configuration, after the data of one program number is reproduced continuously in the first disk order, the data of the next program number is reproduced continuously in the second disk order, and the following program numbers are reproduced. Also for data, a new reproduction mode having a pattern of repeating reproduction in the first and second disc order can be realized. This pattern is more complex than playing back only in a single disc order, and allows the user to enjoy more varied playback.

According to a sixth aspect of the present invention, in the control method according to any one of the third to fifth aspects, a plurality of target disks are identified by consecutive disk numbers, and the disk order is It is characterized in that the number is either ascending or descending. According to this configuration, data of one program number can be sequentially reproduced in any one of ascending order and descending order of disk numbers. Such ascending order and descending order processing are the most basic arithmetic processing as described above for the program number, and can be easily realized by a very simple arithmetic circuit.

According to a seventh aspect of the present invention, in the control method according to the second aspect, the reproducing step sequentially selects the program numbers in ascending order or descending order, and randomly selects one program number. The method is characterized in that the method includes a step of sequentially reproducing one piece of data corresponding to the program number in the order of the selected disks. Claim 8
The invention according to claim 2 is a control method according to claim 2,
The reproducing step includes a step of sequentially selecting a program number at random, and sequentially reproducing one piece of data corresponding to the program number in order of one program number in a randomly selected disc order. . According to the configuration of claims 7 and 8 as described above,
After continuously reproducing the data of one program number in one randomly selected disk order, the data of the next program number is continuously reproduced in a randomly selected different disk order, and the following program numbers A new reproduction mode having a pattern of repeating reproduction in a different disc order selected each time can be realized for the above data. Since this pattern is always played back in a different disc order for each program number, the pattern is more complicated than when playing back only in a preset single or two disc order, and the user is more varied. You can enjoy playing. In particular, since the program number is also randomly selected, the program number is more complicated than when the program numbers are selected in ascending or descending order, and the user can enjoy more varied reproduction. .

According to a ninth aspect of the present invention, the control method according to the first to eighth aspects is grasped from the aspect of the apparatus. That is, a multi-disc player for selecting and reproducing one of a plurality of discs has a control means for performing the reproducing step according to any one of the first to eighth aspects. According to this configuration, the same operation as the first to eighth aspects can be obtained according to the reproducing step to be realized.

[0025]

Embodiments of the present invention will be specifically described below with reference to the drawings.

[1. Configuration] FIG. 1 is a block diagram showing an example of hardware of a multi-disc player to which the present invention is applied, and is a block diagram schematically showing a configuration. As shown in FIG. 1, the multi-disc player includes a display module 10 and an external device 20.

First, the display module 10 includes a display 11
And an input key (KEY) 12 and a control unit 13. Here, the control unit 13 is a unit having a function of controlling the external device 20, determining a display content on the display unit 11, and processing an input from the input key 12. Equivalent to. This control unit 1
Reference numeral 3 includes a memory 14 for storing various data such as operation programs and histories, and various reproduction patterns according to the present invention are stored in the memory 14.

Next, the external device 20 includes a radio 21, two MD playback units 22 and 23, and two CD playback units 2.
4, 25. Here, MD playback unit 2
2 and 23 are application sections 22a and 2 respectively.
3a and the mechanical part (MD / AC1) 22b, (MD / AC1)
2) It is composed of 23b. Similarly, the two CD playback units 24 and 25 respectively include the application unit 24
a, 25a and mechanical parts (CD / AC1) 24b, (CD / AC1)
AC2) 25b. In this case, an existing configuration can be used for the mechanical units 22a, 23a, 24a, and 25a, but the application units 22b, 23b, and 2
4b and 25b are appropriately changed in order to realize the reproduction pattern according to the present invention.

Although the maximum number of continuously reproducible discs in the multi-disc player varies depending on the design of the apparatus, the multi-disc player of the present embodiment is the most common six-disc changer. Of course, the present invention is not limited to the six-sheet changer, but is equally applicable to all multi-disc players capable of switching a plurality of discs.

[2. Operation] In the multi-disc player having such a configuration, first, after the power is turned on, when the user selects “disk” as the device to be used by using the input keys 12, the control unit 13 provides input support to the user. As a display, the identification of the selectable reproduction pattern is displayed on the display 11. For example, the control unit 13
A standard reproduction pattern for reproducing all songs for each disk and an identification of a reproduction pattern for reproducing each song over a plurality of disks are displayed. On the other hand, when the user selects the latter reproduction pattern, the control unit 13 further
A plurality of reproduction pattern options, which are a combination of a disc order and a song order, are displayed. Table 1 below shows examples of such reproduction pattern options.

[0031]

[Table 1] When the user selects an arbitrary reproduction pattern from the reproduction patterns shown in Table 1, the control unit 13 controls the application of the MD reproduction units 22 and 23 and the CD reproduction units 24 and 25 according to the selected pattern. Parts 22a, 2
A signal is sent to 3a, 24a and 25a to cause a predetermined reproducing operation to be performed. Further, the control unit 13 displays an image of the selected reproduction pattern on the display unit 11 and uses the reproduction pattern image display to reproduce a portion (reproduction history) already reproduced on the reproduction pattern or to reproduce in the future. Information on the current playback position, etc. on the playback pattern or other parts (scheduled to be played back) is displayed by line type, symbol, figure, fill, color, etc., and the identification of the currently playing song is indicated by a number. And so on.

In the following, the reproduction pattern A "disc order: ascending order, song order: ascending order", the reproduction pattern C "disc order: ascending order, song order: random" and the reproduction pattern G "disc order: ascending / Descending repetition, song order: ascending order ", playback pattern J
In the case where each of the four reproduction patterns A, C, G, and J, "disc order: random, song order: ascending order", is selected, six discs are sequentially reproduced with reference to FIGS. explain.

FIG. 2, FIG. 4, FIG. 6, and FIG. 8 are explanatory diagrams showing the order of reproduction of the six discs in each of the reproduction patterns A, C, G, and J. In view of this, the number of songs on each of the six disks is the same as the number of songs on each of the six disks of the conventional example shown in FIG. FIGS. 3, 5, 7, and 9 show the reproduction patterns A,
It is a flowchart which shows the operation | movement procedure of the control part 13 for implement | achieving C, G, J, respectively, and a disk number is n,
The song number is m, the minimum disk number is S, and the maximum disk number is L.

[Reproduction Pattern A] As shown in FIG. 2, in the reproduction pattern A "disc order: ascending order, song order: ascending order", the first song of each of the discs 1 → 2 → 3 → 4 → 5 → 6, 1 → 2 → 3 → 4 → 5 → 6 each second song, disc 1
→ 2 → 3 → 4 → 5 → 6 3rd song, Disc 1 → 2 → 3
→ 4 → 6 each 4 songs, disc 1 → 2 → 3 → 4 → 6 each 5 songs, disc 1 → 2 → 4 → 6 each 6 songs, disc 2 → 4 → 6 each 7 songs, disc 2 Reproduction is performed in the order of the eighth tune of → 4, the ninth tune of the disk 4 → the tenth tune.

Then, in order to realize the reproduction pattern A as described above, the control unit 13 operates according to the procedure shown in FIG. That is, when the reproduction pattern A “disc order: ascending order, song order: ascending order” is selected, the control unit 13 first sets the disc number n to the minimum disc number S, as shown in FIG. Set the song number to 1 (step 1
01).

The reason why the minimum disc number is not fixed to 1 is that the disc number may be 2 or more when the maximum number of reproducible discs is not stored. For example, in a six-sheet changer, if disk numbers 1 to 6 are assigned to six disk storage positions, if six disks are stored, the minimum disk number is 1, but the disk number 3 When four disks are stored in the four storage positions marked with 〜 to ６6, the minimum disk number is 3. For the same reason, the maximum disk number is not fixed to 6.

Next, using the identification (n, m) of the music composed of the disk number n and the music number m set as described above as a reproduction command, the MD reproduction units 22 and 23 and the CD reproduction units 24 and
25 application units 22a, 23a, 24a, 2
By sending it to the entire 5a or to only the application section of the playback section to be used, its mechanical section is operated to play back the corresponding music on the corresponding disk (step 102). Thereafter, the process waits for the end of reproduction (step 103).

After this standby state, it is determined whether or not reproduction of the m-th song (n, m) of the disc n has been completed (step 104). If it is determined in step 104 that the reproduction of the song (n, m) has not been completed, the process returns to step 103 and returns to the standby state. On the other hand, if it is determined in step 104 that the reproduction of the music (n, m) has been completed, the disc number n is incremented by 1 (step 105), and a disc having the new disc number n exists. It is determined whether or not (step 106).

If it is determined in step 106 that the disk with the new disk number n does not exist, the new disk number n becomes the maximum disk number L
It is determined whether or not it is greater than (Step 107). If it is determined in step 107 that the new disk number n is not larger than the maximum disk number L, that is, if it is determined that the new disk number n is equal to or smaller than the maximum disk number L, the process proceeds to step 105. Return, add 1 to the disk number n.
At 6, it is determined whether or not a disk with the new disk number n exists. If it is determined in step 107 that the new disk number n is larger than the maximum disk number L, the disk number n is returned to the minimum disk number S, and the music number m is incremented by 1 (step 108).

On the other hand, if it is determined in step 106 that a disk having the new disk number n exists, or if the disk number n and the song number m have been updated in step 108, the disk n
It is determined whether or not the m-th song exists (step 10).
9). If it is determined in this step 109 that the m-th song exists on the disk n,
Then, the identification (n, m) of the music is sent as a reproduction command to reproduce the music. If it is determined in step 109 that the m-th song does not exist on the disk n, it is determined whether or not the reproduction of all the songs on all the disks has been completed (step 110).

If it is determined in step 110 that reproduction of all songs has not been completed, step 1
Returning to 05, the disk number n is incremented by one, and in the following step 106, it is determined whether or not a disk with the new disk number n exists. Step 11
If it is determined at 0 that the reproduction of all the songs has been completed, the process returns to step 101 to start a new disk reproduction.

[Reproduction Pattern C] As shown in FIG. 4, in the reproduction pattern C "disc order: ascending order, song order: random", one song number selected at random in the order of discs 1 to 6 After the music pieces are sequentially played, the music pieces of the next selected one of the music numbers are sequentially played back in the same disc order. For example, a column of song numbers randomly selected
In the case of “5, 1, 10, 7, 4,...”, The fifth track of each of discs 1 → 2 → 3 → 4 → 6, discs 1 → 2 → 3
1 → 4 → 5 → 6 each song, Disc 4 10th song, Disc 2 → 4 → 6 each 7th song, Disc 1 → 2 → 3 → 4 →
The reproduction is performed in the order of the fourth tune of No. 6,....

Then, in order to realize the reproduction pattern C as described above, the control unit 13 operates according to the procedure shown in FIG. As apparent from a comparison between FIG. 5 and FIG. 3 showing the procedure of the reproduction pattern A, the procedure of FIG. 5 includes the same parts as the procedure of FIG.
8 is different in that a music number is set by random calculation and that there is no step of determining the end of reproduction of all music on all disks (a step corresponding to step 110 in FIG. 3). That is, the control unit 13 sets the reproduction pattern C
When "disc order: ascending order, song order: random" is selected, first, as shown in FIG. 5, the disc number n is set to the minimum disc number S, and the song number is set by random calculation (step). 201).

Subsequent to the step 201, the identification (n, m) of the music is sent as a reproduction command, as in the steps 102 and 103 of FIG. 3, and the corresponding music on the corresponding disc is reproduced (step 202). Thereafter, the process waits for the end of reproduction (step 203). Furthermore, after this waiting state,
As in step 104 of FIG. 3, it is determined whether or not the reproduction of the m-th song (n, m) of the disc n has been completed (step 204). If it is determined in step 204 that the reproduction of the tune (n, m) has not been completed, the process returns to step 203 and returns to the standby state. If it is determined in step 204 that the reproduction of the song (n, m) has been completed, the process proceeds to step 10 in FIG.
Similarly to 5 and 106, the disk number n is incremented by 1 (step 205), and it is determined whether or not a disk with this new disk number n exists (step 206).

If it is determined in step 206 that the disk with the disk number n does not exist,
As in step 107 of FIG. 3, it is determined whether the new disk number n is larger than the maximum disk number L (step 207). If it is determined in step 207 that the new disk number n is not larger than the maximum disk number L, that is, if it is determined that the new disk number n is equal to or smaller than the maximum disk number L, the process proceeds to step 205. Returning, the disk number n is incremented by one, and in the subsequent step 206, it is determined whether or not a disk with the new disk number n exists. If it is determined in step 207 that the new disk number n is larger than the maximum disk number L, the disk number n is returned to the minimum disk number S, and the music number m is set by random calculation (step 20).
8).

On the other hand, if it is determined in step 206 that a disk having the new disk number n exists, or if the disk number n and the song number m have been updated in step 208, the process proceeds to step 109 in FIG. Similarly, it is determined whether or not the m-th song exists on the disk n (step 209). This step 20
In step 9, if it is determined that the m-th song does not exist in the disk n, the process returns to step 205 to add 1 to the disk number n. Judge. In step 209, the disk n
If it is determined that there is an m-th song in step 20,
Returning to step 2, the identification (n, m) of the music is sent as a reproduction command to reproduce the music.

[Reproduction Pattern G] As shown in FIG. 6, the reproduction pattern G "disc order: ascending / descending repetition, song order: ascending order"
In each of the first songs of the discs 1 → 2 → 3 → 4 → 5 → 6, the second songs of the discs 6 → 5 → 4 → 3 → 2 → 1, the discs 1 → 2 → 3 → 4 → 5 → 6 3rd song, disc 6 →
4 → 3 → 2 → 1 each 4 songs, Disc 1 → 2 → 3 → 4 →
6 each 5 songs, disk 6 → 4 → 2 → 1 each 6 songs, disk 2 → 4 → 6 each 7 songs, disk 4 → 2 each 8 songs, disk 4 ninth → 10 songs Is played.

Then, in order to realize the reproduction pattern G as described above, the control unit 13 operates according to the procedure shown in FIG. As is clear from comparing FIG. 7 with FIG. 3 showing the procedure of the reproduction pattern A, the procedure of FIG. 7 includes the same parts as the procedure of FIG. It is determined whether the number is an odd number (step 30).
6 to 309) and an even number (steps 310 to 313)
The difference is that a disc is selected in a different procedure and the next song number is selected. That is, when the reproduction pattern G “disc order: ascending / descending repetition, song order: ascending order” is selected, the control unit 13 first sets the disk number n to the minimum disk number S, as in step 101 in FIG. And the music number is set to 1 (step 301).

Subsequent to this step 301, the identification (n, m) of the music is sent as a reproduction command, as in steps 102 and 103 in FIG. 3, and the corresponding music on the corresponding disc is reproduced (step 302). Thereafter, it waits for the end of the reproduction (step 303). Furthermore, after this waiting state,
As in step 104 of FIG. 3, it is determined whether or not the reproduction of the m-th song (n, m) of the disc n has been completed (step 304). If it is determined in step 304 that the reproduction of the music (n, m) has not been completed, the process returns to step 303 and returns to the standby state.

If it is determined in step 304 that the reproduction of the music (n, m) has been completed, it is determined whether the music number m is an odd number or an even number (step 305). Here, if the music number m is an odd number, the discs are sequentially selected in accordance with the procedures of steps 306 to 309 and the process proceeds to the next music number. If the music number m is an even number, steps 310 to 313 are performed. The discs are sequentially selected according to the procedure described above, and the process proceeds to the next music number.

That is, if the music number m is an odd number in step 304, the process proceeds to steps 105 and 1 in FIG.
Similarly to 06, the disk number n is incremented by 1 (step 306), and it is determined whether or not a disk with this new disk number n exists (step 307). If it is determined in step 307 that the disk with the disk number n does not exist, the new disk number n is set to the maximum disk number L, as in step 107 in FIG.
It is determined whether or not it is larger than (Step 308). If it is determined in step 308 that the new disk number n is not larger than the maximum disk number L, that is, if it is determined that the new disk number n is equal to or smaller than the maximum disk number L, the process proceeds to step 306. Then, the process returns and increments the disk number n by one, and then proceeds to step 30.
At 7, it is determined whether or not a disk having the new disk number n exists. If it is determined in step 308 that the new disk number n is larger than the maximum disk number L, the disk number n is set to the maximum disk number L, and the music number m is incremented by 1 (step 309). .

On the other hand, in step 304, the music number m
Is an even number, the disk number n is decremented by 1 (step 310), and it is determined whether or not a disk with this new disk number n exists (step 311).
If it is determined in this step 311 that the disk with the disk number n does not exist, it is determined whether or not the new disk number n is smaller than the minimum disk number S (step 312). If it is determined in step 312 that the new disk number n is not smaller than the minimum disk number S, that is, if it is determined that the new disk number n is equal to or smaller than the minimum disk number S, the process proceeds to step 310. Returning, the disk number n is decremented by one, and in the following step 311, it is determined whether or not a disk with the new disk number n exists. If it is determined in step 312 that the new disk number n is smaller than the minimum disk number S, the disk number n is set to the minimum disk number S, and the music number is incremented by 1 (step 313).

Then, step 307 or step 3
11, when it is determined that a disk with the new disk number n exists, or when the disk number n and the song number m are updated in step 309 or step 313, as in step 109 in FIG. It is determined whether or not the m-th song exists on the disc n (step 314). If it is determined in step 314 that the m-th song exists on the disk n, the process returns to step 302 to identify the song (n, m).
Is sent as a reproduction command to cause the music to be reproduced. If it is determined in step 314 that the m-th song does not exist on the disk n, the process proceeds to step 11 in FIG.
Similarly to 0, it is determined whether or not the reproduction of all the songs on all the disks has been completed (step 315).

If it is determined in step 315 that the reproduction of all the songs has not been completed, step 3
05, if m is an odd number, the disk number n is incremented by 1 in step 306; if it is an even number, the disk number n is decremented by 1 in step 310, and in step 307 or 311 It is determined whether or not a disk with the new disk number n exists. If it is determined in step 315 that the reproduction of all songs has been completed,
The process returns to 1 to start a new disc reproduction.

[Reproduction Pattern J] As shown in FIG. 8, in the reproduction pattern J “disc order: random, song order: ascending order”, the first song in the random order of the discs 1 to 6 and the random number of the discs 1 to 6 2nd songs in order, 3rd songs in random order of discs 1 to 6, discs 1 to 6
4th song in random order of 4,6, discs 1-4,
6 songs in random order, discs 1, 2, 4,
6 songs in random order of 6, 6 songs in random order of discs 2, 4 and 6, 8 songs in random order of discs 2 and 4, 9th to 10th song of disc 4, and so on. Will be

Then, in order to realize the reproduction pattern J as described above, the control unit 13 operates according to the procedure shown in FIG. As is clear from comparing FIG. 9 with FIG. 3 showing the procedure of the reproduction pattern A, the procedure of FIG. 9 includes the same parts as the procedure of FIG. 3, and steps 101 and 105 to 105 of FIG. The difference is that a disk number n is set by random calculation in steps 401 and 405 instead of 108. That is, when the reproduction pattern J “disc order: random, song order: ascending order” is selected, the control unit 13 first sets the disc number n
Is set by random calculation, and the music number is set to 1 (step 401).

Subsequent to step 301, as in steps 102 and 103 of FIG. 3, the identification (n, m) of the music is sent as a reproduction command, and the corresponding music on the corresponding disc is reproduced (step 402). Thereafter, the process waits for the end of reproduction (step 403). Furthermore, after this waiting state,
As in step 104 of FIG. 3, it is determined whether or not the reproduction of the m-th song (n, m) of the disc n has been completed (step 404). If it is determined in step 404 that the reproduction of the tune (n, m) has not been completed, the process returns to step 403 and returns to the standby state.

If it is determined in step 404 that the reproduction of the music (n, m) has been completed, a new disk number n is set by random calculation (step 405), and the same as step 109 in FIG. Next, it is determined whether or not the m-th song exists on the disk n (step 406). If it is determined in step 406 that the m-th song is present on the disk n, the process returns to step 402, where the identification (n, m) of the song is sent as a playback command, and the song is played. Step 40
If it is determined in step 6 that the m-th song does not exist on the disk n, it is determined whether or not the reproduction of all the songs on all the disks has been completed, as in step 110 of FIG. 3 (step 407).

If it is determined in step 407 that reproduction of all songs has not been completed, step 4
Returning to 05, a new disk number n is set by random calculation. If it is determined in step 407 that the reproduction of all the songs has been completed, the process returns to step 401 to start reproducing a new disk.

[3. Effects] As described above, in the multi-disc player of the present embodiment, a patterned playback mode other than the existing all-song playback mode or the simple random mode can be realized. That is, in comparison to the all-song playback mode in which all songs on one disc are always listened in the same order, each song having the same song number over a plurality of discs is different.
Since the songs can be played back sequentially and the playback pattern is more complicated, it is possible to make full use of a plurality of discs to maintain the interest of the user.

Also, unlike the simple random mode,
Since there is a certain pattern of continuously playing the music having the same music number, information such as a reproduction history, a future reproduction schedule, or a current reproduction position in this pattern is displayed on the display unit 11. The user can easily grasp the information on those reproduction patterns. That is, since the user can have a total image of all the songs to be reproduced from the information on the reproduction patterns, the user can more actively enjoy the reproduction of the songs in association with such images.

Further, unlike the case where the identification of a large number of music pieces is registered and the reproduction music piece order data is constructed, the disk and the music piece are sequentially selected in accordance with the pattern, so that a storage means having a large storage capacity is required. There is also an advantage that it is unnecessary.
