Abstract

PURPOSE:To start a performance without newly setting performance program every time a magazine is exchanged by providing a variable characteristic circuit for every magazine and obtaining the output of the variable characteristic circuit from the loaded magazine and performing the programs according to that output. CONSTITUTION:When the magazine is loaded into a player, the output terminal of the variable characteristic circuit 5 is combined with a connection terminal provided on the player side and the output of the variable characteristic circuit 5 is supplied to a characteristic detection circuit 6. When a new performance program preparing instruction exists, a keyboard 7 instructs a display means 11 to display the performance program preparing instruction in order to input a performance program. When the new performance program preparing instruction does not exist, the other performance mode such as an manual performance mode is executed. Thus the performance program is previously prepared for plural magazines and the corresponding program is automatically executed. In such a case, an objective program can be easily selected by freely modifying the contents of the variable characteristic circuit 5.

Description

[Detailed description of the invention] Technical field The present invention relates to a magazine-accommodating disc player.

BACKGROUND ART Recently, magazine-accommodating disk players have been developed which house multiple disks on which audio/video information, etc. are recorded in a housing called a magazine, and enable continuous playback by selecting any one of the disks. being developed. for example,
For a magazine containing several compact discs as shown in Figure 5, 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 the performance program by determining the contents of the discs housed 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.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a magazine-accommodating disk player that makes it easy to reset a 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, each magazine is provided with a variable characteristic circuit, and the output of this variable characteristic circuit is obtained from the installed magazine, and the performance is performed in a manner corresponding to this output. It is configured to execute.

Examples Examples of the present invention will be described below. Figure 1 (A)
and (B) show examples of magazines. A variable characteristic circuit 5 is provided inside the housing of these magazines. The variable characteristic circuit 5 is composed of a plurality of switches, for example, as shown in FIG. 2(A). As such a switch, a so-called digital switch such as a dip switch can be used. By using n switches, 2 to the n power of magazines can be identified. When this magazine is attached to the player, the output end of the variable characteristic circuit 5 is coupled to a connection terminal provided on the player side, and the output of the variable characteristic circuit 5 is supplied to the characteristic detection circuit 6. The characteristic detection circuit 6 generates an identification signal corresponding to this output and supplies it to the system controller 4 (not shown). Another example of the variable characteristic circuit 5 is shown in FIG. 2(B). This circuit has a configuration in which the taps of the voltage divider circuit are switched, and the level of this voltage divider output is converted by an A/D converter provided in the characteristic detection circuit 6 to obtain an identification signal. Various types of variable characteristic circuit 5 can be used as long as different outputs can be set for each magazine.

The configuration of a player that plays a disc stored in a magazine containing such a variable characteristic circuit 5 will be explained with reference to FIG.

In FIG. 3, when the magazine 1 is loaded into the magazine mounting section 2, the magazine mounting detection circuit 3 detects mounting and supplies a mounting detection signal to the system controller 4. The output of the variable characteristic circuit 5 is supplied to a characteristic detection circuit 6. The characteristic detection circuit 6 obtains an identification signal from the supplied signal and supplies it to the system controller 4. System controller 4
Command signals and performance programs are supplied from the keyboard 7. The system controller 4 stores this performance program in the memory 8. The contents stored in the memory 8 are retained even after the power is turned off. 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, when power is supplied to the device and an operation is commanded from the keyboard 7, it is determined whether a magazine is set based on the presence or absence of a mounting detection signal (step Sl). If the magazine is not set, the display means 11 displays a message to mount the magazine (step S2). When the magazine is set (step S1), the identification signal supplied from the characteristic detection circuit 6 is taken in as magazine No. and N (step S3).
). Assuming that there is a performance program for playing the music on the disk stored in this magazine N, that is, a performance program corresponding to magazine N, and N is registered in the memory 8 in advance (step S4), When there is a registered performance program execution command for performing a disc performance using the registered performance program supplied from the keyboard 7 (step S5), the performance program corresponding to the magazine N is fetched from the memory 8 (step S5).
6). According to this performance program, a disc and a song are selected and a series of songs is played (step S7). When this performance ends, this registered performance program mode ends.

When magazine N is not registered (step S4) and when there is no registered performance program execution command (step S5), a new performance program creation command is issued to create a new performance program for the songs recorded in this magazine. It is determined whether the message is coming from the keyboard 7 (step S8). If this instruction exists, the display means 11 is instructed to display a performance program creation instruction so that the performance program can be input from the keyboard 7 (step S9). When the keyboard 7 commands the completion of the performance program creation (step 510), it is determined whether a storage command to save the performance program in the memory 8 has been issued from the keyboard 7. If this storage command exists (step 511), this performance program is held in the memory 8. This performance program includes identification information indicating that it corresponds to magazine N (step 512). When the program has been saved to the memory 8 or is not to be saved, this performance program is executed (step S7).

If there is no new performance program creation command (step S8), another performance mode such as manual performance mode is executed (step 813).

In this way, performance programs can be created in advance for each of a plurality of magazines and stored in the memory, and the performance programs corresponding to the loaded magazines can be automatically executed. In addition, as mentioned above (by making the contents of the variable characteristic circuit 5 freely changeable, 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). , there is an advantage that a desired performance program can be easily selected from among a plurality of performance programs.It is clear that the form of the variable characteristic circuit 5 is not limited to the embodiment, and various forms such as resistance value selection are possible. be.

As described in detail, in the magazine-accommodating disk player of the present invention, a variable characteristic circuit is built into the magazine, and the contents of the identification information set in this circuit are read and the disk is stored in a manner according to the contents. Since it is configured to perform 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 each time the magazine is replaced.
