Music printer
专利汇可以提供Music printer专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a music printer capable of switching the color tone of a light pen by utilizing the output of a least place bit of a port, recording on a music paper transferable a musical line and further printing on the music paper the melody played by a key board.
CONSTITUTION: A magnetic head coil is connected to the bit terminal of a port C in which a binary code signal is issued and the recording is achieved so that a plurality of parallel tracks 530 to 535 as many as a number of the bits are formed on a magnetic tape on which the head coil is transferred by a head 51 at a constant speed to a direction shown by the arrow mark. Subsequently, if the tape 52 is regenerated, the binary codes recorded in the port C can be taken out in turn. In order to perform the printing of the music, a bias voltage E
0 is generated by the OR output of the all bits in the binary code signals applied to the port C while the voltage KE is generated by the combination of the bits, and the total voltage E
0 +KE is impressed to a moving coil of the light pen to print the melody.
