摘要： A droplet ejection apparatus includes a main power supply, power cutoff detecting means, a standby power supply, residual vibration detecting means, storage means, and ejection failure detecting means. When cutoff of the main power supply is detected, an actuator is driven by a driving circuit, the residual vibration detecting means detects the residual vibration of the diaphragm displaced by the driving of the actuator, and the storage means stores the vibration pattern of the residual vibration of the diaphragm detected by the residual vibration detecting means and/or the information obtained from the vibration pattern. The ejection failure detecting means include an oscillation circuit that oscillates in response to an electric capacitance component that varies with the residual vibration of the diaphragm.

摘要： An apparatus is provided for ejecting liquid drops while eliminating a special sensor (a photosensor) and improve detection accuracy for abnormal ink drop ejection. When the detecting an abnormal ink drop ejection, a drive circuit outputs an actuator-driving voltage in addition to an original drive voltage with a contact of a changeover switch located in a first position. The original drive voltage causes the electrostatic actuator to be driven. Thus, the vibrating plate is vibrated, whereby ink drops are ejected. Thereafter, the electrostatic actuator is charged with a charge according to the actuator-driving voltage. The charging voltage corresponds to the residual vibration of the vibrating plate. Then, the contact of the changeover switch is switched to a residual vibration-detecting circuit. Thus, the residual vibration-detecting circuit is supplied with the charging voltage to thereby output a residual vibration waveform.
摘要翻译：提供一种用于在消除特殊传感器（光电传感器）的同时喷射液滴并提高异常墨滴喷射的检测精度的装置。当检测到异常墨滴喷射时，驱动电路除了位于第一位置的切换开关的触点之外，还输出致动器驱动电压以及原始驱动电压。原始驱动电压导致静电致动器被驱动。因此，振动板振动，从而喷出墨滴。此后，根据致动器驱动电压对静电致动器进行充电。充电电压对应于振动板的残余振动。然后，转换开关的接触被切换到残余振动检测电路。因此，剩余振动检测电路被供给充电电压，从而输出残留振动波形。
