PURPOSE:To enjoy feeling of a roulette not only competing the skillfulness of singing in a KARAOKE (orchestral accompaniment without lyrics) providing a display mechanism which displays a hit display when the evaluation result matches with a beforehand set result. CONSTITUTION:When one finishes his singing, his skillfulness of singing is evaluated by an evaluating circuit 2 and the evaluation result is displayed on a display device 3 in terms of marks signals. The marks signals outputted by the circuit 2 are inputted to a marks collating device 1, which discriminates the matching of lower two digits of the numerals. When these two digits of the numerals are discriminated to be matched, a matching signal is outputted and when not, a unmatching signal is outputted to a throttle mechanism circuit 4. The circuit 4 actuates its throttle mechanisms when it receives a matching signal, randomly varying numerals are displayed on the device 3 every fixed time and the numerals are stopped by a stop mechanism 6. When the stopped numerals are discriminated to be matched, a hit signal is outputted to a display controlling circuit 5 and is displayed on t he device 3. |
