Patent ID: 6896363

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