Printer

摘要

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.

主权项

1. A printer comprising:
a feeding portion that is configured to feed a print medium in a first direction; an ejection portion that is configured to eject liquid toward the print medium; a carriage on which the ejection portion is mounted and which is configured to reciprocate in a second direction, the second direction being a direction that is orthogonal to the first direction; a guide shaft that extends in the second direction and that supports a first end portion of the carriage in the first direction; a rail member that extends in the second direction and that is disposed facing the guide shaft; a cap that covers the ejection portion from a first side, the first side being a direction toward which the ejection portion ejects the liquid; a first pressing portion that is provided on a second end portion of the carriage and that presses a first surface, which is a surface on the first side of the rail member, the second end portion of the carriage being an end portion on an opposite side to the first end portion of the carriage in the first direction; an eccentric member that has a rotating shaft portion and an eccentric shaft portion, the rotating shaft portion being axially supported by the second end portion of the carriage and extending in the first direction, and the eccentric shaft portion being eccentric with respect to the rotating shaft portion; a regulating portion that is supported by the eccentric shaft portion and that is disposed on a second side of the first pressing portion such that the regulating portion faces the first pressing portion with the rail member interposed between the regulating portion and the first pressing portion, the regulating portion coming into contact with a second surface of the rail member and regulating movement of the carriage to the first side, the second side of the first pressing portion being an opposite side to the first side of the first pressing portion, and the second surface of the rail member being a surface on the second side of the rail member; and a prohibition portion that fixes the rotating shaft portion and that prohibits rotation of the rotating shaft portion.
