PROBLEM TO BE SOLVED: To provide a droplet jetting apparatus which can selectively jet many types of droplets from one nozzle while making the electrical constitution of the device simple as much as possible.SOLUTION: A data generating circuit 60 incorporated in an ASIC 54 includes: a first jetting mode memory circuit which stores information related to a plurality of first jetting modes; a time-series information memory circuit which stores time-series information of a jetting mode which associates one of the plurality of first jetting modes, for each jetting timing of the nozzle; a second jetting mode memory circuit which stores information related to a plurality of second jetting modes, which have more types than those of the plurality of first jetting modes; and a jetting mode selecting circuit which selects a jetting mode at an optional jetting timing among the plurality of second jetting modes in reference to the first jetting modes corresponding to the optional jetting timing and at least one of the previous and subsequent jetting timings included in the time-series information. |
