BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus, and more particularly, to a karaoke apparatus for detecting an erroneous input of a music number.

[0002]

2. Description of the Related Art Conventionally, when singing using a karaoke apparatus, a song to be sung is selected from a song book in which a song name, a singer's name and a song number are described in association with each other, and the song is assigned to the song. The tune number is input from the operation unit of the karaoke apparatus main body or the remote control apparatus.

[0003] The song number is usually composed of a plurality of digits, and when inputting a song number using the operation section of the karaoke apparatus main body or the remote control device, for example, even if an incorrect number is entered by only one digit, it is noticed. However, when the user realizes that the input was erroneous after the performance of the music, the performance of the selected music is canceled and the input is performed again.

In a conventional karaoke apparatus, for example, as shown in FIG. 4, when an operation of inputting a music number is performed on an operation section of a karaoke apparatus main body or a remote control device (step Q1), the input music is inputted. Based on the number, a search is made for a song table stored in association with a song number previously stored in the memory and a song name (step Q2), and it is checked whether a song number that matches the input song number is present in the song table. (Step Q3). If there is a song number that matches the input song number in step Q3, the karaoke device displays on the display unit of the karaoke device that the song selection reservation has been completed, and completes the song selection reservation process (step Q4). If there is no song number that matches the entered song number in the song table, a message indicating that the song number has been input is displayed on the display unit, and the song selection reservation process ends (step Q5).

Therefore, when a song number is input from the operation unit of the karaoke apparatus or the remote control device, an incorrect number is entered by one digit, and the song number corresponding to the incorrectly entered song number is registered in the song table. In this case, the music corresponding to the erroneously input music number is selected.

However, in such a conventional karaoke apparatus, even if a wrong number is input by one digit when inputting a music number, the erroneous input is made in the music table. If the song number is registered, the song was selected and the song was played as it was.
It is necessary to cancel the selection of the tune in which the performance has begun and re-enter the tune number, which causes a problem that the karaoke apparatus is not easily used. In particular, since the karaoke apparatus stores a plurality of music selection numbers and performs the music in the music selection order, usually, even if the music number is input, the music is not immediately played, and only when the music becomes the music order. If a song number is entered incorrectly because the song is played, the user will notice the mistaken input when the song with the incorrectly entered song number is played, cancel the performance song, and re-enter the song number. The song with the designated song number is turned to the end of the song selection order, and there is a problem that the karaoke apparatus is not easily used. Further, in the conventional karaoke apparatus, when a song number of a singing song is input, the input song number is sequentially stored, and the song data of the song number is played in the input order. However, even if a song having the same song number is input first and is in a waiting state, the same song is played without any notice and the karaoke apparatus is not easily used.

Therefore, in the karaoke apparatus 1, when the tune number to which the check digit is added is input, the above-mentioned arithmetic processing is performed on the input tune number, so that the correctness of the input tune number can be determined. . That is, when the original song number is "12345", the song number input by the karaoke apparatus 1 is "123451". The resulting check digit does not become “1”, and it can be determined that the input music number has an error.

Next, the CPU 2 determines whether or not the input music number is correct based on the calculation result of the check digit (step S3).
The input music number storage area of the SIMM 10 is searched to check whether the same music number as the currently input music number is stored (step S4).

When the same music number is not stored in the SIMM 10, the CPU 2 judges that there is no music of the music number inputted this time among the unplayed music whose performance has been reserved, and
The song name-song number table (in FIG. 2, it is indicated as a song table) stored in the SIMM 10 is searched to determine whether there is the same song number, that is, the karaoke apparatus 1
It is checked whether there is song data of a song number (song name) that can be played (step S6). If the inputted song number is in the song name-song number table, the entered song number is stored in the input song number of the SIMM10. The completion of the music selection reservation is displayed on a TV monitor or the like, and the processing is terminated (step S7).

If the input music number is not in the music name-music number table in step S6, there is no music data, so that the CPU 2 displays an error message to that effect and ends the processing (step S8).

In step S4, if the same music number as the currently input music number is stored in the input music number storage area of the SIMM 10, the CPU 2 determines that the same music has already been reserved. Then, an error message to that effect is displayed, and the process ends (step S8).

Further, in step S3, the CPU 2
If the input song number is incorrect according to the check digit calculation result, an error message is displayed indicating that the input song number is incorrect, and the process ends (step S).
8).

As described above, the karaoke apparatus 1 uses the song number to which the check digit, which is predetermined correctness / error judgment information, is added in advance as the song number for specifying the song data of the song to be selected. When the added music number is input, a check digit calculation process is performed on the music number to determine the correctness of the input music number.
Therefore, an erroneous input of a tune number can be detected before the tune of the erroneously input tune number is played, and the usability of the karaoke apparatus 1 can be improved.
