Abstract: A printing device includes a printing unit that performs printing on a medium using liquid. A liquid container includes a liquid containing chamber, which is capable of containing the liquid supplied to the printing unit, and a liquid inlet, which allows the liquid containing chamber to be filled with the liquid. A shell accommodates the printing unit and a portion of the liquid container. The liquid container includes a projecting portion that projects out of the shell. A protection member covers the projecting portion. The protection member projects out of the shell in a direction that is the same as a direction in which the liquid container projects out of the shell.

Abstract: There is provided a technique that enhances the detection accuracy of a liquid contained in a tank unit. A printer 10 is provided with a tank unit 40A. The tank unit 40A includes a plurality of ink tanks 43A and a plurality of ink cylinder portions 46A. Each of the plurality of ink cylinder portions 46A is connected with corresponding one of the ink tanks 43A by a tube 47, such as to cause ink contained in the corresponding ink tank 43A to flow into the ink cylinder portion 46A. Each of the ink cylinder portions 46A is provided with a pair of terminal pins 96a and 96b that are used for detection of ink. A horizontal sectional area of the ink cylinder portion 46A at a height position where the pair of terminal pins 96a and 96b are provided is smaller than a horizontal sectional area of the ink tank 43A at a corresponding height position.

Abstract: A technique of reducing the possibility that a liquid remains in a buffer chamber is provided. There is provided a liquid supply device configured to supply a liquid to a liquid ejection head. The liquid supply device comprises a liquid containing chamber configured to contain the liquid; an air communication path configured to include a first connection portion at one end that is connected with the liquid containing chamber and an air outlet port at the other end that is open to the atmosphere; and a buffer chamber provided in the middle of the air communication path. The air communication path includes a connection path that is located on a downstream side of the buffer chamber in the air communication path in a flow direction of a fluid from the air outlet port toward the liquid containing chamber and is configured to include a second connection portion at an upstream end connected with the buffer chamber. When the first connection portion is exposed to the liquid in the liquid containing chamber, the second connection portion is placed in a lower area in a vertical direction of the buffer chamber.
