CONSTITUTION:When a registered performance program executing instruction does not exist and a magazine N is not registered in the outside memory 11, the display of the preparing instruction of a new performance program is instructed to newly prepare the performance program of a music registered in this magazine. When a memory instruction exists, this performance program is preserved in the outside memory 11. This prepared performance program includes identifying information which shows that it copes with the magazine N. When the preservation of the program in the memory 11 is finished or the program is not preserved in the memory 11, such a controlling flow chart is finished and the other flow chart like an manual performance mode, for example, is executed. Thus the program coping with the loaded magazine can be automatically executed.

Description

[Detailed description of the invention] Flaming mound 1 The present invention relates to a magazine-accommodating disc player.

Recently, magazine-accommodating disk players have been developed that house multiple disks on which audio/video information, etc. are recorded, in a housing called a magazine, and enable continuous playback by selecting any disk from among the housings. being developed. for example,
For a magazine containing several compact discs as shown in Figure 6, a song with a playing time of about 3 minutes (here, a song is a single piece of music or a group of interconnected pieces of audio/video information of an event, etc.). It is possible to store approximately 120 songs (referring to one group of information), and it is easy to cover and store them by your favorite genre, such as jazz or enka. Generally, in such a magazine-accommodating disk player, a performance program indicating the play order is created before playback, and a program play mode can be selected in which songs stored in the magazine are played continuously based on this play program. It is designed for the convenience of users.

By the way, in such a magazine-accommodating disk player, each time the magazine is replaced, it is necessary to reassemble the performance program corresponding to the music stored in the magazine, or if a plurality of performance programs are stored in advance. Since it is necessary to select a performance program by determining the contents of the discs stored in the magazine, the operation is troublesome, especially when a plurality of magazines are used or when a magazine is shared by a plurality of players.

Therefore, it is an object of the present invention to provide a four-magazine storage disk player that makes it easy to reset the performance program each time a magazine is replaced.

In order to achieve the above object, in the magazine-accommodating disk player of the present invention, a recording medium in which the performance program of each magazine is stored is mounted together with the magazine, and the performance program corresponding to the mounted magazine is loaded from the recording medium and the performance program is read into the disc player. It is configured to perform a performance.

Friend-U Hereinafter, embodiments of the present invention will be described. FIG. 1 shows an example of a disc player that accommodates this magazine.

This player is equipped with a magazine 1 and an external memory 11 such as an IC card, and a remote control keyboard 7 or a main body keyboard 13 supplies performance programs, various commands, etc. to the control circuit of the player.

The circuit configuration of such a player will be explained with reference to FIG.

In FIG. 2, when the magazine 1 is mounted on the magazine mounting section 2, the magazine mounting detection circuit 3 detects the mounting and supplies a mounting detection signal to the system controller 4. Command signals and performance programs are supplied to the system controller 4 from the keyboard 7 or the main keyboard 13. The system controller 4 stores this performance program in the internal memory 8 or external memory 11. The stored contents of memories 8 and 11 are retained even after the power is turned off.

Further, the system controller 4 takes in performance information such as a performance program stored in the external memory 11 and target song information as necessary. The discs housed in the magazine are transported to a predetermined performance position in the performance section 10 by a disc transport mechanism 9. The performance section 10 reads the information signal recorded on the disk, demodulates the information signal, and supplies the demodulated output to a power amplifier and speaker (not shown), or a CRT.

The system controller 4 controls the disk performance mechanism 9, the performance section 10, and display means for displaying performance information and the like.

Next, the performance of the device will be explained. First, power is supplied to the device, and the keyboard 7 or main keyboard 13 is
When an operation is commanded, it is determined whether the magazine is loaded or not based on the presence or absence of a mounting detection signal (step 81). If not set, display means 1
1 to install a magazine (step S).
2). When the magazine is set (step S1), it is determined whether the external memory 11 is set (step 83). This determination is based on the presence or absence of a detection signal from a mounting detection switch (not shown). If the memory 11 is not installed, the display means 12 displays a message to install an external memory (step 84). When the external memory 11 is installed, a performance program is read from this memory and stored in the internal memory 8 (step S5). Next, the system controller 4 instructs the system controller 4 to search for the unique information of one disk, other disks, or a plurality of disks at a predetermined position in the set magazine (step S6), and reads the disk unique information (step S6).
7). Disk-specific information includes a number unique to that disk,
The information may include the number of songs, performance time, type of song, so-called TOC information, etc., as long as it can identify the disc. Step S8: A performance program execution command is issued from the keyboard 7 or the main body keyboard 13 to cause the controller 4 to execute the performance program.
), if a Pli performance program including this disk-specific information exists (step 89), that performance program is executed (step 816).

If there is no performance program corresponding to the disk specific information (step S9), it is determined whether there is a request to create a new performance program from the keyboard 7 or the main body keyboard 13 (step 510). If this request does not exist, terminate this control program, e.g.
The performance moves to manual operation. If this request does not exist, the program area of the memory 8 is cleared to erase the stored performance program and prepare for inputting a new program (step 511). If there is a request to create a new performance program, the display means is instructed to display a program creation instruction (step 512). When a signal indicating that the program input is completed is input from the keyboard 7 or the main body keyboard 13 (step 5).
13) It is determined whether there is a storage command for this performance program (step 514). If this storage command does not exist, the performance program is executed (step 816); if the storage command exists, the created performance program is stored in the external memory (step 815), and this performance program is executed (step 816). step 816). In this way, the performance program stored in the external memory is executed. Here, when a plurality of programs are stored in the external memory 11, the title of each program is further displayed in step S9, and the program selected by the keyboard 7 or the main body keyboard 13 is executed.

FIG. 4 shows another embodiment. In FIG. 4, parts corresponding to those in FIG. 2 are designated by the same reference numerals, and explanations of these parts will be omitted. In this embodiment, the magazine itself has a built-in variable characteristic circuit 5 for the purpose of identifying it, and when the magazine 1 is attached to the player, the variable characteristic circuit 5 is connected to a characteristic detection circuit 6. The characteristic detection circuit 6 is
An identification signal indicating a particular magazine is provided to the system controller 4 based on the output of the variable characteristic circuit. The other configurations are similar to the configuration shown in FIG.

The performance operation of such an apparatus will be explained with reference to the control flowchart shown in FIG. First, power is supplied to the device,
When an operation is commanded from the keyboard 7 or main body keyboard 13, it is determined whether the magazine is set based on the presence or absence of a mounting detection signal (step 521).
. If the magazine is not set, the display means 11 displays a message to mount the magazine (step 522). When the magazine is set (step 821), the identification signal supplied from the characteristic detection circuit 6 is taken in as magazine N01N (step 523). Next, external memory 11
is set (step 824),
If the memory 11 has not been set, the display means 12 displays a message to set the memory 11 (step 525). When the memory 11 is set, in response to the presence of a registered performance program execution command from the keyboard 7 or the main body keyboard 13 (step 826), a performance program for playing the songs on each disc stored in the magazine N, i.e. , the performance program corresponding to magazine N is stored in memory 11.
(Step 527)
). If the performance program corresponding to magazine N is registered (step 826), the performance program corresponding to magazine N is fetched from the memory 11 (step 82).
8). According to this performance program, a disc and a song are selected and the song is played (step 529). When this performance ends, this control flowchart ends.

When there is no registered performance program execution command (step $26) and when magazine N is not registered in the external memory 11 (step 527), a new performance program is created for the music recorded in this magazine. It is determined whether a performance program creation command is issued from the keyboard 7 or the main body keyboard 13 (step 530). When this command exists, the display means 12 is commanded to display an instruction to create a performance program so that the performance program can be input from the keyboard 7 or the main body keyboard 13 (step 531). When the completion of creating a performance program is commanded from the keyboard 7 or the main body keyboard 13 (step 532), it is determined whether a storage command to save this performance program in the memory 11 has been issued from the keyboard 7 or the main body keyboard 13 (step 532). Step 533). When this storage command exists, this performance program is stored in the external memory 1.
Hold at 1. This created performance program includes identification information indicating that it corresponds to magazine N (step 534). When the program has been saved to the memory 11 or is not saved (step 533), the performance program is executed (step S7), and this control flowchart is ended. If there is no new performance program creation command (step S8), this control flowchart is terminated, and another control flowchart for, for example, manual performance mode is executed.

In this way, performance programs can be created in advance for each of a plurality of magazines and stored in the external memory, and the performance programs corresponding to the loaded magazines can be automatically executed. Furthermore, by making the contents of the variable characteristic circuit 5 freely changeable as described above, a plurality of performance programs can be stored in advance in one magazine, and the contents of the variable characteristic circuit 5 can be set according to the preference at that time. This has the advantage that a desired performance program can be easily selected from a plurality of performance programs. Various types of variable characteristic circuit 5 can be used, such as a resistance value selection circuit, a variable output voltage circuit, and a digital switch circuit. Alternatively, the identification code attached to the magazine may be optically read by photoelectric conversion. In addition, although Figure 3 shows an example in which the contents of the external memory are first imported into the main body, it is also possible to first read the disk-specific information and then import only the program containing that data from the external memory into the main body. good.

In addition, as external memory, magnetic card, IC card,
Various types of optical cards and magnetic disks can be used.

As explained above, the magazine-accommodating disc player of the present invention has a configuration in which the performance program for each magazine is stored in the external memory. When performing a performance, it is preferable that the performance can be quickly started in a predetermined manner without having to set a new performance program for the magazine every time the magazine is replaced.
