发明名称 FLUID EJECTION DEVICE
摘要 A fluid ejection device includes a fluid storing unit and a fluid outlet. A fluid pressing unit presses the fluid storing unit and causes fluid to flow from the fluid outlet. A connection pipe has an end that is connected to the fluid outlet. A fluid ejection unit ejects the fluid, which is received from a fluid intake port to which the other end of the connection pipe is connected, in a pulse-like manner according to a drive signal generated by a fluid-ejecting control unit. An ejecting-instruction input unit receives a fluid ejecting instruction. If the pressure in the fluid storing unit is equal to or higher than an upper limit value in a range determined with reference to a target pressure value, the drive signal is not generated. When the pressure in the fluid storing unit is lower than the upper limit value, the drive signal is generated.

主权项 1. A fluid ejection device comprising: a fluid container including a fluid storing unit that stores fluid and a fluid outlet formed in the fluid storing unit; a fluid pressing unit configured to press the fluid storing unit and cause the fluid to flow out from the fluid outlet; a connection pipe, one end of which is connected to the fluid outlet; a fluid ejection unit including a fluid intake port, to which the other end of the connection pipe is connected, and configured to eject the fluid, which is taken in from the fluid intake port, in a pulse-like manner according to a drive signal; a pressure detecting unit configured to detect pressure in the fluid storing unit; an ejecting-strength input unit configured to receive an input for setting ejecting strength of the ejecting of the fluid by the fluid ejection unit; a pressing control unit configured to control the fluid pressing unit to bring the pressure in the fluid storing unit close to a target pressure value determined according to the ejecting strength; an ejecting-instruction input unit configured to receive an instruction input for ejecting the fluid from the fluid ejection unit; and a fluid-ejecting control unit configured to output the drive signal to the fluid ejection unit, wherein when the ejecting-instruction input unit receives the instruction input, if the pressure in the fluid storing unit is equal to or higher than an upper limit value in a first predetermined range determined with reference to the target pressure value, the fluid-ejecting control unit does not output the drive signal and, if the pressure in the fluid storing unit is lower than the upper limit value, the fluid-ejecting control unit outputs the drive signal.
