ABSTRACT:
A discharge device for discharging a medium, includes: a discharge-driving roller, provided in a downstream of a liquid emitting head for emitting liquid onto the medium, for being driven to rotate; a discharge-driven roller, biased by a biasing mechanism toward the discharge-driving roller, for being brought into contact with the discharge-driving roller to be rotated by the discharge-driving roller; a discharge frame, to which the discharge-driven roller is attached, having a posture changeable between a contact posture that brings the discharge-driven roller into contact with the discharge-driving roller and a release posture that moves the discharge-driven roller away from the discharge-driving roller; and an engagement portion, provided on the discharge frame, for engaging with an outside region of the medium inserted between the discharge-driving roller and the discharge-driven roller toward an upstream against a force applied by the biasing mechanism, the outside region being a region other than a liquid-emitted region of the medium onto which the liquid is to be emitted, wherein the medium is discharged by rotation of the discharge-driving roller, and the outside region of the medium moves the engagement portion away to change the posture of the discharge frame from the contact posture to the release posture, when the medium is inserted between the discharge-driving roller and the discharge-driven roller toward the upstream.
