Discharge device of injected medium and liquid injection equipment with said discharge device

Abstract

A discharge device for discharging a medium, includes: a discharge-driving roller (26), provided downstream of a liquid emitting head (21) for emitting liquid onto the medium, for being driven to rotate; a discharge-driven roller (27), biased by a biasing mechanism towards 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 (33), to which the discharge-driven roller is attached, having a posture changeable between a contact posture that brings the discharge-driven roller (26) into contact with the discharge-driving roller (26) and a release posture that moves the discharge-driven roller (27) away from the discharge-driving roller (26); 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. <IMAGE>

Description

technical field [0001] The present invention relates to a discharge device that discharges an ejected medium such as recording paper by rotation of a discharge drive roller, and a liquid ejection device such as an inkjet recording device including the discharge device. [0002] Here, the so-called liquid ejecting device is not limited to the use of an inkjet type recording head, recording devices such as printers, copiers, and facsimiles that record on a recording medium by ejecting ink from the recording head, and also includes alternative inks, and A device for ejecting a liquid corresponding to the application from a liquid ejection head corresponding to the recording head to an ejected medium corresponding to a recording medium, and causing the liquid to adhere to the ejected medium. [0003] As the liquid ejection head, in addition to the above-mentioned recording head, a colorant ejection head used in the manufacture of a color filter such as a liquid crystal display, an...

Problems solved by technology

[0008] However, in the above-mentioned conventional structure, since the operation lever and the link mechanism are provided, the structure is complicated, and the number of parts becomes a cause of cost increase.

Since the toothed roller is displaced by the structure of the operating lever and the link, the accuracy of the displacement of the toothed roller is low. In this case, although the data recording area is not damaged, it may sometimes be lightly aligned with the printing surface of the CD. light touch
