    摘要: 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.

    摘要: A liquid discharge apparatus includes a nozzle, a pressure chamber and a liquid supply portion that supplies the liquid to the pressure chamber. A discharge pulse generating unit generates a discharge pulse to discharge the liquid. The viscosity of the liquid is no less than 8 millipascal-seconds. The nozzle has a first portion with a discharge side that has an opening area smaller than that of a pressure chamber side and a second portion that communicates with an end portion of the discharge side. An opening area of the second portion is no greater than 1/9 of the opening area of the pressure chamber side. The discharge pulse has a decompression portion that decompresses the liquid to lead a meniscus in the second portion to the first portion and a compression portion that compresses the liquid to discharge the liquid before the meniscus returns to the second portion.
