A printer includes a feeding portion for feeding a print medium in a first direction, an ejection portion for ejecting liquid, a carriage, a guide shaft, a rail member, a first pressing portion, an eccentric member, a regulating portion, and a prohibition portion. The carriage includes the ejection portion and reciprocates in a second direction which is orthogonal to the first direction. The guide shaft extends in the second direction and supports the carriage. The rail member is disposed facing the guide shaft. The first pressing portion presses a first surface of the rail member. The eccentric member has a rotating shaft portion and an eccentric shaft portion that is eccentric with respect to the rotating shaft portion. The regulating portion comes into contact with a second surface of the rail member, and regulates movement of the carriage. The prohibition portion prohibits rotation of the rotating shaft portion.

Printer

A printer feeds a print medium in a first direction. A carriage reciprocates an ejection portion in a second direction orthogonal to the first direction. A side wall portion of a frame body has a first surface which is an external surface on a first side of the frame body, extending toward a third direction along liquid ejection. An upper wall of the frame body has a second surface which is an external surface on the first side of the frame body, extending toward the first side from an end portion of the side wall portion on a side of fourth direction opposite to the third direction. An object member having a pattern indicating a position of the carriage in the second direction extends further to the first side than the first surface and further to the third direction side than an opening portion formed on the second surface.

A printer includes a guide shaft, a rail member, print head units, a carriage and a first pressing portion. The first pressing portion includes a first contact member, a first support shaft, a first arm member and a first urging member. The first contact member comes into contact with a first end portion. The first support shaft is disposed between a position facing one of the two support portions in a rail-side end portion and a position facing the other support portion. The first support shaft stands in a fourth direction opposite to a third direction in which an ejection portion ejects liquid. The first arm member swings around the first support shaft, and supports the first contact member on a swinging end side. The first urging member urges the first arm member in a direction in which the first contact member comes into contact with the first end portion.

An inkjet printer printing includes a cartridge mounting portion in which a ink cartridge can be inserted, and a detection portion including a detection switch having a leading end portion and detecting whether the ink cartridge is inserted in the cartridge mounting portion in accordance with a displacement amount of the leading end portion, the leading end portion being penetratingly supported via a first elastic member so as to be displaceable such that the leading end portion protrudes to the outside, and a protruding portion provided on the leading end portion side of the detection switch via a second elastic member so as to be displaceable and protrudes toward the cartridge mounting portion, the second elastic member having an elastic modulus that is smaller than an elastic modulus of the first elastic member and causing the first elastic member to be deformed when the second elastic member is deformed.

Inkjet printer

A cleaner unit to clean an inkjet head, ejecting ink onto a recording medium, and an ink conveyer tube, conveying the ink to the inkjet head, of an inkjet printer in cleaning liquid, is provided. The cleaner unit includes an air-liquid two-phased cleaner conveyer tube, which conveys air-liquid two-phased cleaner, and a cleaner spout, which is connected to an upstream-side end of the ink conveyer tube and to a downstream-side end of the air-liquid two-phased cleaner conveyer tube with respect to a fluid flow, and through which the air-liquid two-phased cleaner is supplied to the ink conveyer tube.
