Therefore, an identification mark is attached to the housing of the magazine, and the disc contents (for example, song titles, etc.) for each magazine are stored in advance in the player's built-in memory, and when the magazine is installed, this is read and the magazine is identify,
The applicant has proposed a device that displays the contents of a corresponding magazine storage disk to facilitate the operator's selection of music.

In this case, although the song selection operation is facilitated by displaying the disc contents of the magazine, after the song selection is completed and the selected song begins to be played, it is no longer essential to display the song title until the end of the performance.

On the other hand, there may also be a need to display screen information (hereinafter referred to as song content information) corresponding to the song content, such as lyrics, explanatory text, and image images, as information regarding the content of famous songs on the magazine-accommodating disc.

Accordingly, it is an object of the present invention to provide a magazine-accommodating disc player that allows an operator to easily obtain music content information regarding the disc content of a loaded magazine and the music content within the disc. It is to be.

In order to achieve the above object, the magazine storage disc play V of the present invention is provided with magazine discrimination means for discriminating the mounted magazine, and based on the output of this magazine discrimination means, the magazine storage disk play Magazine content information indicating the contents of the disc loaded is read from the memory and supplied to the image display means, while song content information indicating the content of the songs on the disc is inputted by another means such as a barcode reading device. is configured to supply the image to the image display means in accordance with a command.

Support 1 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 mounting on the play V is detected by the mounting detector 2a, the identification code reading circuit 2 reads the mark. The output of this reading circuit 2 is the microprocessor (
The disks stored in the magazine are supplied to the magazine identifying means 31 of the system control unit 3 constituted by M (hereinafter referred to as J), and the magazine number is identified. The recorded information signal is read by the pickup 4. This recorded information signal is demodulated by the demodulation circuit 5,
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 the circuits 1 to 5 in accordance with a manual operation or a performance command based on a performance program inputted in advance. In such control, the currently played song information in Table 1 is used to determine the currently played song.

As this currently played music information, so-called TOC information, track number, index number, absolute address, etc. are used.

Various command signals, performance programs, etc. are input to the system section 11111 section 3 via the keyboard 7.

In order to facilitate such input operations, a barcode reader 8 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. 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. Content information can be entered relatively easily. Necessary pieces of music content information are input and stored and held as music content information in the player's memory 10 via the system control unit 3. Further, a card reader 8a is provided for reading information from a separately provided IC card or magnetic card in which music content information is stored in advance, and its output is supplied to the system control unit 3 via a decoder 9.

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

The display control circuit 20 temporarily stores the music content 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 music content information, and supplies this to the CRT 22 via an external terminal 21a. The CRT 22 forms an image according to the pattern signal and the horizontal and vertical synchronizing signals supplied via the external terminal 21b. Note that, instead of the CRT 22, a liquid crystal display or the like having a relatively large display area may be incorporated.

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

Next, the control operation of the system control section 3 will be explained with reference to the flowchart of FIG. 3(A). First, although the above magazine content information is stored in the memory 10,
It is assumed that the above-mentioned music content information has not been stored yet, and that a predetermined number is attached to the installed magazine.

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 the magazine is 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).

The identification code reading circuit 2 reads the identification mark of the set magazine and supplies an output corresponding to the mark to the magazine discrimination means 31, and the magazine discrimination means 31 obtains the magazine number based on this output. .

This magazine number is imported (step 83).

It is determined whether magazine content information corresponding to this magazine number is stored in the memory 10 (step 84). If the image is not stored, data indicating that it is not registered is fetched from the ROM 35 in order to display the image (step S5), and this data is sent to the display control circuit 2.
0 (step S6), and a display command is supplied to the display control circuit 20 (step 89). As a result, CRT22
A message indicating that there is no magazine content information is displayed.

On the other hand, if magazine content information corresponding to the magazine number is stored, the magazine content information is fetched (step 37). As described above, this magazine content information includes the song title, 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 magazine content information and sequentially converts it into image information using the character generator 21 according to the display command and supplies it to the CRT. In this way, CRT
Display the contents of the magazine on the screen, end this subroutine, and return to the main control program. FIG. 4(A) shows an example of displaying the titles of songs recorded in the magazine. As shown in this figure, the user selects a song from among the displayed song titles and instructs its performance, or creates a performance program by referring to the displayed song titles. In this example, TNO is the track number,
IND represents an index number, and IMIE represents a performance time, which are displayed by a control program (not shown).

Next, inputting music content information will be explained. When a command indicating the input of music content information is issued from the console via the keyboard 7, the main control program shifts to the first routine shown in FIG. 3(B). That is, when the above-mentioned command is supplied, the system control unit 3 enters a state in which it is possible to import music content information, and instructs the display circuit 36 to display that input from the barcode reader is possible (step 5).
31). The operator refers to the magazine content information (song title, etc.) displayed on the screen and reads the song content information corresponding to the song whose content is desired to be displayed from the data book using the barcode reader 8.
Enter sequentially using . When a command to the effect that the input is completed is issued via the keyboard 7 (step 532), the supplied song content information is sent to a predetermined location in the memory 10 via the system control unit 3 (shown as song content information in FIG. 1). (step 533). Then return to the main control program. The music content information includes identification information, and can be selectively read based on the current 2iii Hata music information of the performance control circuit 6. Alternatively, an IC card or the like provided with pre-stored song content information may be attached to the card reader 8a, and the necessary information may be read therefrom. In this way, the song content information is stored in the memory 10.

When the performance of a predetermined piece of music is commanded by manual operation or a performance program, the performance starts.

When the currently played piece information is set in the performance control circuit 6, the main control program shifts to the subroutine shown in FIG. 3(B), and the currently played piece information supplied from the performance control circuit 6 is read. (Step S1). The music content information corresponding to this performance music information is fetched from the memory 10 and supplied to the display control circuit 20 (step S2), and then a display command is supplied to the display control circuit 20 (step S3). For example, when the currently played song is rLOVEis XXXXJ, the display on the CRT 22 in this case is as shown in Figure 4 (B).
will be shown. Thereafter, the program returns to the main control program, and when the currently played music is changed, the subroutine is repeated again from step S1.

In this way, when the magazine is loaded, magazine content information is displayed on the display screen, and when a song starts playing, information corresponding to the content of the song, ie, lyrics, etc., is displayed on the display screen.

By reading the barcode attached to the lyrics card as shown in FIG. 2 (A) as a command to play a predetermined song, the song can be selected and the lyrics of the song can be displayed on the screen. I can do it. , index numbers, etc. are used as currently played song information, and screen display information such as lyrics may be displayed in a so-called scrolling manner according to the progress of the performance.In addition to lyrics, narration, pictures, musical scores, etc. may also be displayed. good. In the embodiment, 1 is used to suppress the increase in memory 8.
The music content information corresponding to the magazine is inputted after the magazine is loaded, but if the memory capacity is large, it is possible to store the music content information of songs stored in a plurality of magazines. Furthermore, data input may be simplified by providing an IC card or the like in which music content information for each disc is stored in advance with the disc, thereby providing convenience to the user.

As explained above, the magazine storage disc play V of the present invention is provided with a magazine discriminating means for discriminating the mounted magazine, and based on the output of this magazine discriminating means, the magazine containing disc play V of the present invention is Magazine content information indicating the contents of the disc is read from the memory and supplied to the image display means, and song content information indicating the content of the songs on the disc is inputted by another means, and this is sent to the image display means in accordance with a command. Because it is structured so that only the necessary amount of song content information is input and stored, memory can be saved.In addition, the magazine contents are displayed before selecting a song, and when selecting a song, it is displayed when playing. Since image information such as lyrics or images corresponding to the content of the song can be displayed, the display screen can be used effectively, which is preferable.
