Abstract:
A printer includes a cartridge is mounted in a cartridge holder, an needle-tube having an ink flow path, an protrusion disposed around the needle-tube as viewed from an axial direction of the needle-tube, and an elastic-member configured to be deformed in a direction from a tip end to a base end of the needle-tube, in which the elastic-member changes a relative positional relationship between a tip end position of the needle-tube and a tip end position of the protrusion from a first state in which the tip end position of the protrusion is located further away from the base end of the needle-tube than is the tip end position of the needle-tube, to a second state in which the tip end position of the protrusion is closer to the base end of the needle-tube than is the tip end position of the needle-tube upon being deformed by an external force.
