Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a karaoke system using a so-called CD changer that sequentially plays a plurality of compact discs, for example.

(b)) Prior Art In recent years, so-called CD changers that can selectively and continuously reproduce a plurality of discs have become popular. In such a CD changer, the disc number and song number to be played are entered into the player by operating the operation buttons arranged on the front of the player, and the player side stores the information input in this way in the RAM. At the time of playback, such information is read out from the RAM and the designated songs are played back in sequence.

By the way, recently such a CD changer has been commercialized as a karaoke system. This kind of CD changer usually has several dozen discs stored in the player, and by inputting the index number attached to a karaoke book, etc. into the player, a desired song can be programmed into the player. has been done.

(c) Problems to be Solved by the InventionHowever, as mentioned above, when the number of discs stored in a CD changer increases to several tens, the number of songs to be played also increases to several hundred, and of course it is necessary to deal with the problem. There are hundreds of different index numbers. When there are hundreds of types of index numbers, it becomes difficult to distinguish between the index numbers, which may lead to the operator inputting the wrong index number to the player. Particularly when this type of CD changer is used in a restaurant or the like, it is difficult to receive song requests from multiple customers at the same time, making it easy for the operator to make the above-mentioned erroneous inputs. The present invention aims to solve such problems.

B.) Means for Solving the Problems In view of the above problems, the present invention provides a disc player capable of selectively reproducing a plurality of discs, and a disc number and track recorder for a plurality of discs stored in the disc player. an external storage object that stores address information such as a number, a reader that reads and scans the external storage object, a receiver disposed within the disc player that receives the signal read by the reader, and the receiver. The disc is configured to include a RAM that sequentially stores signals received by the RAM, and a reproducing unit that sequentially reproduces the disc according to the address information stored in the RAM.

Furthermore, the configuration includes a converting section that converts the signal received by the receiving section into an index number, and a display section that displays this index number.

(E) Operation The address signal to be input to the player is easily input by the reader. Further, the above information read by the reader and input to the player is converted into an index number in the external storage and then displayed on the display section to check whether there are any errors in the input.

(F) Example Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a karaoke book in which lyrics and the like are written. The karaoke book (1) includes song titles (1a) and lyrics (
1b), and a barcode (1d) encoding the corresponding disc number and song number in addition to the index number (1C). Such barcode (1d) is read by being scanned by barcode league (2) in the block diagram shown in FIG. The barcode read in this manner is transmitted as a radio wave signal by the barcode reader (2), and is received by the receiver (3) disposed on the player side. The radio signal received by the receiving section 13) is processed by a signal processing circuit (4) and then transferred to a microcomputer (hereinafter referred to as microcomputer) (5).

The signal indicating the disc number and song number (hereinafter referred to as address signal) input to the microcomputer (5) in this way is 1 (AM

While being transferred to and stored, the signal converter +71 converts it into a signal indicating an index number, and this index signal is further input to a driver circuit (8) and displayed as an index number on a display unit (9). (
(See Figure 6). Here, if the content displayed on the display section (9) is different from the index number to be input, the operator can press the 9 cancel button placed on the Parco reader (2) to cancel the 9 RAM (The signal stored in 61 is erased.

By repeating the above operations, several types of songs are stored in RAMK. Incidentally, here, the display section (9) displays only the index number when the player is inputting information. If no next index signal is input for a predetermined period of time, the total number of songs stored up to that time is displayed (see FIG. 4). Furthermore, the size of the display section (9) is made large enough that the operator can visually recognize the index number even from a certain distance.

Next, the reproduction operation will be explained according to the flowchart shown in FIG. Incidentally, such a flowchart is shown in the block diagram shown in FIG.
mo ry ) fl (stored in l.

When a playback start signal is sent to the operation input section (111) inside the player by the operation button on the player or the remote control, this signal is transferred from the operation input section ■ to the microcomputer (5), and the player is set to playback mode. When the player is set to playback mode, it is determined in step 1 of the flowchart whether or not the address signal described above exists in the RAM (61).
If the response signal in RAM+61 exists, step 2
The address signal stored first is read out from the RAM 161. On the other hand, if the determination in step 1 is NO, the reproduction mode is stopped.

When the address signal is read in step 2, this signal is transferred to the driver circuit (81) in step 3, and the corresponding index number is displayed on the display section (91).Furthermore, at the same time, the address signal is transferred to the reproducing section ( 121, and the playback unit 13 selects and plays the desired song based on the disc number indicated by this address signal and the song number on the disk (step 4).During the selection and playback of such a song, it is possible to cancel the song. When the signal is received by the operation input unit Uυ, it is determined in step 5, and the playback of that song is stopped and the playback operation of the next song to be played is started.On the other hand, such a cancel operation If not, then the end of the song is determined in step 6.The end of the song is detected by the song interval detection section (131) in the block diagram of FIG. Unit 0 constantly monitors the signal reproduced from the disc, and when it detects an inter-song signal at the joint between two songs in the signal, it outputs an inter-song signal, that is, a signal indicating the end of the song.Stella 160 discrimination. If NO, the process returns to step 5, and the determinations in step 5 and step 6 described above are repeated.

Thus, the player continues to play the song until it receives a song cancellation signal or detects an inter-song signal.

When the inter-song signal is detected in step 6, the player is set to a pause state. Thereafter, the process returns to step 1 and it is determined whether the address signal of the next song to be played exists in the RAM+71. If the determination result is YES, the address signal is read out in step 2, the corresponding index number is displayed in step 3, and the corresponding song is played in steps 4 and subsequent steps.

In the manner described above, the player continues playing until no address signal is detected in the RAM 161. and RAM
When all the songs corresponding to the song information stored in the player 161 are played back, in step 1, it is detected that there is no address signal for the song to be played in the RAM+61, and the player shifts from the play mode to the stop mode.

(G) Effects of the Invention As described above, according to the present invention, information on the music to be played is input to the player simply by scanning a barcode with a barcode reader, making the operation extremely simple. In addition, the signal input in this way is converted into a signal indicating an index number and then displayed as the index number on the display section, so the operator can check the quality of the input information by looking at the display section. can be confirmed, thereby preventing incorrect input of song information.
