PROBLEM TO BE SOLVED: To provide a KARAOKE sing-along machine which avoids the double registration of a selected KARAOKE sing-along music piece if prescribed conditions are satisfied when the same musical piece as the KARAOKE sing-along musical piece selected by a singer exists in the KARAOKE sing-along musical pieces registered for reservation. SOLUTION: When an operator inputs the music number of the music to be played by operating an operation section 12, a CPU section 7 temporarily stores music number data in a RAM 7b. This CPU section 7 section adds reservation number data, reservation time data and playing completion data to the music number data and stores the data in a playing music information memory section 15. Just before the registration of the playing music management data, the CPU section judges whether the inputted playing music is to be registered or not according to a reservation registration mode and the CPU section emits an alarm to a speaker 16 and a display section 13 in the case of the failure in registration. |
