Each nozzle ejects a main droplet and a sub-droplet smaller than the main droplet consecutively. Each nozzle can change a deflection amount in an ejecting direction of the main droplet along the intersecting direction. A control section performs, in a case where a defective nozzle exists in the nozzles, a control of deflecting the ejecting directions of the main droplets ejected from a nozzle positioned within a predetermined distance from the defective nozzle toward a landing position of a main droplet that should have ejected from the defective nozzle.

Abstract: A sample and hold circuit takes a sample of the current flowing through an inductor of a buck switched-mode power supply (SMPS) at substantially the middle of the low side portion (50 percent point during low side switch ON) of the pulse width modulation (PWM) period.
