Sheet music printing system

Claim 2

A sheet music printing system comprising: a music data inputting device for inputting data on a sheet music; a data processing device for processing data from said music data inputting device into predetermined processing codes; a first memory device for storing the processing codes outputted by said data processing device; an editing device for editing outputs of said first memory device according to a predetermined program; a second memory device for storing music codes outputted by said editing device; a font memory for storing printing patterns corresponding to said music codes; and a photo-composing machine for forming a block copy for said sheet music according to the music codes from said second memory device and the printing patterns from said font memory.

Claim 3

A system as claimed in claim 1, in which in printing a serial note, where with a bar start point as an original point, coordinates of the n-th note in said serial note are designated by Pn (x n ,y n ), coordinates of notes in said serial note are those at the heads of said notes when said notes are of pure tone and are averages of coordinates at the heads of said notes when said notes are of chord, and where N is the number of notes, a left average coordinates P L (x L , y L ) and a right average coordinates P R (x R , y L ) are defined as follows: with with and an inclination (a) of a line connecting notes in said serial note is:

Claim 4

A system as claimed in claim 1 or 2, which comprises an operating panel having a forwardly sloped surface, said operating panel being provided with: a desk type music data inputting device for inputting music data to said data processing device by providing various music symbols and printing instructions with said operating panel; a display device for performing display for introducing initial setting data and music data according to a predetermined program; and a memory control circuit for storing music data inputted by said music data inputting device, causing said display device to display said music data thus stored in a message area therein, moving said music data thus displayed to a predetermined display region on a screen of said display device after confirming that said music data is correct, and transferring said music data to said first memory device, whereby printing codes are formed by successively inputting data on a sheet music while confirming whether or not inputted data are correct with the aid of said display device.
