Abstract

PURPOSE:To maintain a good recording with easier judgement and adjustment of running conditions of a recorder by detecting the size of ink particles jetted from a nozzle head. CONSTITUTION:Flows 21a-21c of ink grown in a nozzle head 1 are passed through a charging electrode 30 to charge. They pass near a detection electrode 43 of a sensor 40 provided with a notch 42 for passing the ink particles on a ceramic base plate 41 to accumulate the charge of the ink particles therein. The charge is fed to a signal processing circuit 50, the output signal of which is inputted into a comparator 60 to be compared with the reference voltage Ec. Signals exceeding the reference voltage Ec1 are normal hence requiring no processing. When signals Eo exceeds the reference voltage Ec2, a processing signal is provided to adjust the output signal value of an information signal source 20 so that the ink particles are jetted normally. When they are below the reference voltage Ec2. The adjustment of the information signal source 20 allows no processing and an alarm 70 is actuated to generate a warning.
