    摘要： An ink droplet eject apparatus comprises a plate-shaped member defining a conical ink droplet eject chamber increasing from an eject port to an opening, and a vibrating plate covering the opening. A spacer is disposed between the vibrating plate and the plate-shaped member surrounding the opening. An annular space is delimited by the spacer. An ink flow path is formed in the spacer. The vibrating plate is excited so as to generate an intermittent liquid flow of an ink W in the ink droplet eject chamber in the direction of the eject port. An actuator can arbitrarily control an amount of displacement of the vibrating plate and a generation time of displacement during the excitation.

    摘要： An amplifier section is supplied with an electric signal outputted from a light-sensitive detector. The amplifier section comprises an amplifying circuit for amplifying the electric signal into an amplified signal having an amplified level. A producing section produces a control signal on the basis of the amplified signal and a reference voltage. A resistor section is connected to the amplifying circuit in parallel. The resistor section has a variable resistance which is varied in accordance with the control signal. A capacitor section has a capacitor and connects the input of the amplifying circuit and the output of the amplifying circuit through the capacitor in response to the control signal.
