ABSTRACT:
An ink jet recording apparatus that makes a recording of a measured input at a time occurring at a predetermined cycle and includes a control section for making the recording at the time by printing dots in the form of a segment in a recording sheet width direction. The segment corresponds to a variation of a measured input between a time and a time before such time. For example, the apparatus prints a segment connecting a position corresponding to a measured input value at a certain time to a position corresponding to a measured input at a time before such certain time, or the apparatus prints a segment connecting positions respectively corresponding to a minimum measured input value and a maximum measured input value between a certain time and a time before such certain time. Accordingly, the apparatus produces a printed line apparently close to a line obtained by a continuous recording system, although the recording is intermittent and thus takes place at a predetermined cycle. An advantage is that a conspicuous fluctuation in flow rate can be reproduced as faithful to the actual situation as possible.
