Description

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

*t*a Recently, multiple discs on which audio/video information, etc. have been recorded are housed in a housing called a magazine, and any disc within the housing can be selected and played continuously. A disc player has been 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 disc player, when the user needs to know the contents of the disc stored in the magazine, it is necessary to take out the disc again and check it, or to write a separate memo in advance. be. Further, if a plurality of performance programs are stored in advance in the player, it is necessary to know the performance program corresponding to the magazine, and an improvement in such handling is desired.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a magazine-accommodating disc player that allows an operator to easily know the contents of a mounted magazine.

In order to achieve the above object, the magazine-accommodating disc player of the present invention is provided with a magazine discriminating means for discriminating the mounted magazine, and based on the output of the magazine discriminating means, the contents of the discs accommodated in the magazine are determined. When the magazine is loaded (hereinafter referred to as display information), the information is read from the memory and is supplied to the screen display means.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIG. Magazine 1 is provided with an identification mark as already proposed separately by the applicant, and magazine 1
When the attachment detector 2a detects that the mark is attached to the player, the identification code reading circuit 2 reads the mark. The output of this reading circuit 2 is the microprocessor (
The magazine identification means 31 of the system control unit 3 (hereinafter referred to as MPU) identifies the magazine number. The disc stored in the magazine is taken out to a predetermined performance position by a transport mechanism (not shown), and the recorded information signal is read by the pickup 4.

This recorded information signal is demodulated by a demodulation circuit 5, and a demodulated signal such as an audio or video signal and a control information signal such as an address signal are obtained. The demodulated signal is supplied to a power amplifier and speaker (not shown) or a CRT to reproduce recorded information. The control information signal is supplied to the performance control circuit 6 to appropriately control the pickup 4 and the like. The performance control circuit 6 appropriately controls the performance section constituted by the device and circuits 1 to 5 in accordance with a performance program or a performance command by manual operation. In such control, currently played music information indicating the currently played music is used. This currently played music information is, for example, so-called TOC information, track number, index NO1 absolute address, etc., and appropriate information may be used as necessary.

Various command signals, performance programs, etc. are input to the system control section 3 from the keyboard 7. In order to facilitate such input operations, a barcode reader 8, which will be described later, is provided. The output of the barcode reader 8 is converted by a decoder 9 into a signal readable by the MPU and supplied to the system control unit 32 via an interface 34.

The barcode reader 8 is configured as shown in FIG. 2(B), and a light beam from a light emitting diode 81 passes through a ball lens 82 and irradiates the barcode printed on a recording medium 86, and its reflection The light is read by phototransistor 83. The output of the phototransistor 83 is amplified by an amplifier 84, shaped into a waveform by a waveform shaping circuit 85, and supplied to the decoder 9. Using this barcode reader 8, as shown in FIG. All song names, their addresses,
The lyrics and the like can be input relatively easily. The above data book has a code table corresponding to the alphabet and a code table corresponding to the 50 sounds, magazine identification code,
It is also possible to input memo-like matters. This information is stored and retained as display information in the player's internal or external memory 10 via the system control unit 3. A configuration using an external memory has been separately proposed by the applicant, and for example, a so-called IC card or the like is used.

The display information is read by the reading means 32 as necessary and supplied to the display control circuit 20.

The display control circuit 20 temporarily stores the display information in a built-in register and supplies it to the character generator 21 along with vertical and horizontal synchronizing signals at appropriate display timing. The character generator 21 generates a pattern signal corresponding to the above display information, and sends this to C via an external terminal 21a.
Supplied to RT22. CRT22 receives the above pattern signal,
An image is formed according to the horizontal and vertical synchronization signals supplied via the external terminal 21b. Note that a liquid crystal display or the like having a relatively large display area may be used instead of the CRT 22. These indicators may be provided within the player.

The system control circuit 3 loads necessary information into its processing memory 33 based on the control program stored in the ROM 35, executes information processing, and supplies the result to the corresponding circuit or displays it on the display panel 36.

Next, the operation of the apparatus will be explained with reference to the flowchart of FIG. 3(A). First, when the device is powered on, execution of a main control program (not shown) is started. After the initial operation is executed, this subroutine is entered and the output of the mounting detector 2a is read to determine whether a magazine has been mounted (step 81). If the magazine is not installed, a message that it should be installed is displayed on the display panel 36 (step 82). Identification code reading circuit 2
reads the identification mark of the set magazine and supplies an output corresponding to the mark to the magazine discriminating means 31, and the magazine discriminating means 31 obtains the magazine number based on this output. After reading this magazine number (step S3), it is determined whether display information corresponding to this magazine number is stored in the internal or external memory 10 (step 84). If it is not stored, unregistered display data is fetched from the ROM 35 to display that line (step 85), and this data is supplied to the display control circuit 20 (step S6). The display control circuit 20 then receives the display command (step 89) and displays C.
The above data is displayed on the RT 22 as image information.

If display information corresponding to the magazine number is stored, the display information is fetched (step 87).

As described above, this display information includes performance programs, song titles, memo-like items, etc. that correspond to the magazine.

After supplying this to the display control circuit 20, a display command is issued (steps S8 and 89). The display control circuit 20 temporarily stores the display information and sequentially converts it into image information by the character generator 21 according to the display command and displays it on the CRT.
supply to. In this way, the contents of the magazine are displayed on the CRT screen, this subroutine ends, and the process returns to the main control program. FIG. 4(A) shows an example of displaying the titles of songs recorded in the magazine. In the manual operation mode, for example, the user selects a channel from among the displayed song titles as shown in this figure. In this example, TNO is the track number, IN
D represents an index number and TIME represents a performance time, which are displayed by a control program (not shown).

In the main control program, the performance program mode or manual operation mode is selected and the performance is started. Note that when the program performance mode is selected, the relevant performance program and its display information are taken in from the memory 10 in the main control program, and are shown in FIG. 4 (C), for example.
) The song titles are displayed in the order of performance. During the performance, a subroutine as shown in FIG. 3(B) is executed. That is, as described above, currently played music information indicating the absolute address or title of the currently played music is fetched from the performance control circuit 6 (step 81), and display information corresponding to this played music information is fetched from the memory 10. Step S2: Add color information, etc. and supply it to the display control circuit 20.
), then supplies a display command to the display control circuit 20 (step 83).

For example, if the currently playing song is rsUrT I IN M
When it is INERJ, the display on the CRT 22 in this case is emphasized by changing the color of the song title portion shown in FIGS. 4A and 4C to a different color from the others or by changing its brightness.

Incidentally, as shown in FIG. 4 (8), the currently played piece may be displayed in a large size.

Note that the number of songs stored in a given magazine is quite large, and it is difficult to display all of them on one screen, so a scroll display is adopted as shown in Figures 4 (D) and (E). be done. Furthermore, in addition to the song title, necessary items such as the performer's name and recording L] may be displayed.

As explained above, in the magazine-accommodating disk player of the present invention, when a magazine is attached to the disk player 47, the contents of the disk accommodated in the magazine are output as an image signal. It is preferable that the content of the magazine is displayed on the screen by a suitable display device such as the above or by providing a display screen on the player itself, since it becomes easy to confirm the contents of the magazine.
