    摘要： A piezoelectric motor includes a driven body configured to rotate around a rotation axis, a first piezoelectric vibrator configured to transmit a driving force to the driven body, a moving mechanism configured to move the first piezoelectric vibrator in directions approaching and separating from the rotation axis, and a second piezoelectric vibrator configured to transmit a driving force to the moving mechanism. The moving mechanism includes a screw shaft disposed along the directions and configured to rotate around an axis with the driving force of the second piezoelectric vibrator and a holding section configured to screw with the screw shaft and hold the first piezoelectric vibrator.

    摘要： An ink refill container includes a container main body including an ink storage chamber, an ink outlet-forming portion provided on an end portion of the container main body forming an ink outlet that allows the ink to flow out from the ink storage chamber, and a valve provided in the ink outlet-forming portion configured to openably seal the ink outlet, in which the ink outlet-forming portion includes a positioning portion on an outer side of the ink outlet-forming portion. in which the positioning portion is closer to the container main body than the valve is to the container main body in a central axis direction of the ink outlet, and in which the positioning portion partially abuts against an ink tank when the valve is opened for refilling the ink to the ink tank, to thereby position the valve relative to the ink tank.

    摘要： A liquid container comprises a liquid supply port provided in a bottom wall, a first chamber configured to contain a liquid, a second chamber configured to contain the liquid and to include at least one sub-chamber having a smaller dimension in the X direction than that of the first chamber, a partition wall configured to part the first chamber from the second chamber, and a connecting hole configured to connect the first chamber with the second chamber. The second chamber is connected with the liquid supply port, and the first chamber is connected with the liquid supply port via the connecting hole and the second chamber. The liquid contained in the first chamber is flowed from the connecting hole into the second chamber and is subsequently introduced through the sub-chamber to the liquid supply port.

    摘要： A liquid container including a liquid storing chamber that stores a liquid, a first member including a cylindrical first side wall surrounding at least a portion of the liquid storing chamber, a first opening surrounded by a first end portion of the first side wall, and a second opening surrounded by a second end portion of the first side wall, a liquid outlet member including an outlet through which the liquid flows out, the liquid outlet member being attached to the first opening, and a second member joined to the first member, the second member sealing the liquid storing chamber from a second opening side. When viewed in a central axis direction of the first member, a joint between the first member and the second member is formed outside an area surrounded by a boundary between the first member and the second member in the liquid storing chamber.
