Abstract

본 발명은 사용이 편리하고 저가이면서도 계속적으로 소망하는 곡을 자동연주 할 수 있는 바코드를 이용한 디지탈 피아노 장치에 관한 것으로, 이를 위하여, 바코드로 된 전체 악보를 스캔하여 바코드 신호를 판독하기 위한 바코드 판독 수단과, 상기 판독된 바코드 신호를 A/D 변환하여 RAM에 제공하는 데이타 변환부와, 상기 데이타 변환부에 데이타 변환을 위한 제어신호를 제공하고 상기 RAM에서의 악보 데이타의 저장 및 인출을 제어하는 시스템 제어부와, 상기 시스템 제어부로부터의 제어신호에 의거하여 상기 RAM에서 판독되어 인출되는 악보데이타를 D/A 변환한 다음 합성하여 출력하는 합성부를 구비한 것이다.The present invention relates to a digital piano device using a barcode that is easy to use, inexpensive and can continuously play a desired song. To this end, a bar code reading means for reading a bar code signal by scanning a whole score of bar codes And a data conversion unit for A / D converting the read barcode signal to a RAM, and a system for providing a control signal for data conversion to the data conversion unit and controlling storage and retrieval of score data in the RAM. And a synthesizing unit for D / A converting the music score data read out from the RAM based on a control signal from the system control unit, and then synthesizing and outputting the music data.
