Abstract

PURPOSE:To add a new music piece even though rewriting to a memory means such as CD-ROM with which postscript is difficult, is ceased, by additionally and successively storing playing data of new music pieces to be added into a postscriptable second memory means. CONSTITUTION:For example, in the case of a recorded instrumental music reproducing system, a control section 2 for controlling whole operation is connected thereto with an input device 1 through which operating instructions such as a start and stop of reproduction are inputted, a CD-ROM 4 on which music data for a plurality of music pieces (for example, 2,000 music pieces) and image data for a plurality of music pieces (for example, 4,000 music pieces) are stored, and a hard disc 5. The CD-ROM 4 is not postscriptable but has a large storage capacity so as to be cheap, but the hard disc 5 is postscriptable. The operational program of the control section 2 is stored in a program memory 3. Further, the control section 2 is also connected thereto with an MIDI interface circuit 6 and an image reproducing device 9. Music data is amplified by a mixing amplifier 7 and is outputted from a speaker, and image data are outputted from a monitor 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic music player.

[0002]

2. Description of the Related Art Conventionally, as an example of a music reproducing device, a karaoke device using a laser disk on which music information and video information of a plurality of music pieces are recorded has been widely popular. In such a laser disc type karaoke apparatus, one disc has 20 to 30 songs recorded therein, and one disc is added each time a new song or the like comes out. A typical karaoke device has 2000 to 3000 songs, and the number of discs is 100 to 150.
There is a tendency for the number of sheets to increase and the storage space to increase.

However, if the storage space becomes large, it may not be possible to install it depending on the location, and in the worst case, some disks may have to be discarded.

Therefore, in order to solve these problems,
It has better storage capacity than a laser disk, for example MIDI
(Musical Instrument Digital Interface) A device using performance information of the standard has been proposed. With such a device, one CD-ROM (540 MB) can easily record about 5000 songs.

[0005]

However, in the karaoke apparatus, it is necessary to add new songs steadily, but if the new songs are written in a CD-ROM that cannot be additionally recorded, the new songs are re-written in a new CD-ROM. I had to write it down. But it would be very unreasonable to have it rewritten for a few new songs. CD-RO that can be additionally recorded
There is also M, but the cost is very high, and the capacity of a write-once hard disk is small.

The present invention has been made to solve the above-mentioned problems, and the number of times of rewriting to a non-recordable storage means such as a CD-ROM is reduced as much as possible, and new songs can be added at any time. An object is to provide an electronic music player.

[0007]

In order to achieve this object, the electronic music reproducing apparatus of the present invention comprises a first storage means in which performance data of a plurality of music pieces are stored in advance, and performance data of designated music pieces. And a writable second storage means for storing performance data of an additional music piece.

[0008]

In the electronic music reproducing apparatus of the present invention having the above structure, the performance data stored in the first storage means is read out by the output means and output as a voice or an image. The performance information of new songs added every month is sequentially stored additionally in the second storage unit that can be additionally recorded. If the second storage means overflows, both information of the first storage means and the second storage means may be collectively stored in a new storage means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The present embodiment shows an example in which the present invention is embodied in a karaoke apparatus, and FIG. 1 is a block diagram showing its configuration.

The control unit 2 for controlling the operation of the entire karaoke apparatus has an input device 1 for instructing the start and stop of reproduction and a CD-recording music information and image information for a plurality of songs. The ROM 4 and the hard disk 5 are connected. The CD-ROM 4 is an inexpensive and large-capacity type that cannot be additionally recorded, and the hard disk 5 is additionally recordable. The operation program of the control unit 2 is stored in the program memory 3.

Further, the control unit 2 has a MIDI interface circuit 6 and a MID as a music reproducing means for converting the musical tone information read from the CD-ROM 4 into a music signal.
The I sound source unit 11 is connected. MIDI sound source section 11
A mixing amplifier 7 and a speaker 8 are connected to each other, and the music information from the MIDI sound source 11 is amplified by the mixing amplifier 7 and output from the speaker 8.

The control unit 2 is also connected to a video reproducing device 9 for converting the image information read from the CD-ROM 4 into a video signal. A monitor 10 is connected to the video reproduction device 9, and image information from the video reproduction device 9 is displayed on the monitor 10.

Next, the operation will be described.

Initially, the number of pieces of music information stored in the CD-ROM 4 is 2000, the number of pieces of image information is 4000, the number of pieces of music information added every month is 30, and the number of pieces of image information added every month is 60. The state of the CD-ROM 4 and the hard disk 5 at this time is shown in FIG. Here, the capacity of the CD-ROM 4 is 540 MB (megabytes), and the capacity of the hard disk 5 is 105 MB. The above-mentioned program memory 3 has a capacity of about 10 MB and is stored in the hard disk 5. The music information has an average of 60 KB per information (kilobyte, 1 MB is 1000 KB), and the image information has an average of 40 KB per information.

Initially, the CD-ROM 4 contains 2000 pieces of music information and 4000 pieces of image information, which means that a total information capacity of 280 MB is stored. The hard disk contains 10 MB of program memory. If 30 pieces of music information and 60 pieces of image information are added to the hard disk 5 every month, 4.2 MB will be added to the hard disk 5 each month. Therefore, after 22 months, 102.
It becomes 4MB and the capacity is full.

At this time, 4.2 MB for the next month is added to 1
Replace 06.6 MB with a new CD-ROM that has 386.6 MB of information, which is 280 MB already stored in the CD-ROM 4. Then, by setting the hard disk 5 to only 10 MB of the program memory, it is possible to additionally write for 20 months or more.

As a method of adding information to the hard disk 5, a method of directly copying from a floppy disk drive or the like, or a method of distributing by communication from a remote place using a telephone line or the like can be considered.

As is clear from the above description,
According to the karaoke apparatus of this embodiment, monthly new work information may be sequentially added, or the CD-ROM may not be rewritten every month, and rewriting may not be performed for about 22 months. It will be cheaper.

The present invention is not limited to the embodiments described in detail above, and modifications can be made without departing from the spirit of the invention.

[0021]

As is clear from the above description, according to the electronic music player of the present invention, the CD-ROM
The number of times of rewriting of the storage means that cannot be additionally written such as is as small as possible, and new songs can be added at any time.
