PURPOSE:To decrease the number of pen recorders and to constitute an efficient system by exercising time-division control over plural trigger signals differing in input time through a controller, and giving a discrimination code to an input data signal and recording it over the same channels of pen recorders. CONSTITUTION:A trigger signal 4 and a data signal 5 are inputted to a recorder controller (RCU) 6, and transmitted to pen recorder 1 through a time-division control circuit to be recorded. When data signals 5 differing in input time are inputted to the same recorder 1, discrimination codes showing generation sources are given to them. Thus, the same recorder 1 is usable in common, so the data signals 5 to be inputted simultaneously are forecasted previously to decide on the number of recorders to be installed. The number of pen recorders is decreased when n>m>p, where (p) is the maximum number of signals 4 and 5 inputted simultaneously, (n) is the number of signals 4, and (m) is the number of pen recorders. |
