Patent number: 7578567Abstract: A liquid detecting container includes a cartridge case having a sending passage for sending out liquid, buffer chambers by the end of the sending passage, and a sensor unit disposed facing the buffer chambers. A sensor chip in the sensor unit includes a sensor cavity communicating with the buffer chambers, a vibration plate closing an opening side of the sensor cavity opposite to the side communicating with the buffer chambers, and a piezoelectric element disposed on the surface of the vibration plate opposite to the surface facing the sensor cavity; emits a vibration wave to the sensor cavity and the buffer chambers through the vibration plate, receives a reflected wave from the buffer chambers through the vibration plate, and then converts the reflected wave into an electrical signal. The compliance values of the buffer chambers are set ten times greater than the compliance value of the sensor cavity.Type: GrantFiled: December 12, 2005Date of Patent: August 25, 2009Assignee: Seiko Epson CorporationInventors: Junhua Zhang, Takahiro Katakura, Takayoshi Katsumura
