PROBLEM TO BE SOLVED: To provide a playing reservation device in which the preparation of the request of karaoke musics is made previously before going to a karaoke shop and the request of the musics can be simply performed in the karaoke shop. SOLUTION: Music numbers of musics desired to be sung are written on a PC card 1 by selecting the music numbers of the musics by referring to an index book 7 and by inputting the numbers to an exclusive registering machine 2 while inserting the PC card 1 into the machine 2 in a household. When the PC card 1 is set to a commander 3 by bringing it to the karaoke shop and the batch transmission key or the sequential transmission key is operated, the musical numbers stored on the PC card 1 are transmitted to a karaoke device 4 as request musics. Consequently, even though the music numbers of the musics are not manually inputted, the karaoke musics are simply requested so that the previously requesting musics is never forgotten. |
