Abstract

PURPOSE:To efficiently remove refuse such as paper dust at the position where fuzing of paper fibers of a recording medium occurs, prevent an ink ejecting port from being clogged and maintain character quality, by providing a cleaning member in the vicinity of and on the upstream side of an image recording part at a position for making contact with a bent part of the recording medium. CONSTITUTION:A sheet S fed downstream to a platen roller 2 is bent along the platen roller 2, and is fed by being clamped at the bent part thereof by the platen roller 2 driven to rotate and tacky rollers 3, 3. Refuse such as paper dust and fuzz of paper fibers on a printing surface of the sheet S are printed is removed from the surface of the sheet by being adhered to the tacky rollers 3, 3. The refuse adhered to the rollers 3, 3 is adhered to a strongly tacky roller 12 tackier than the rollers 3, 3, whereby the rollers 3, 3 are constantly maintained in a clean state. Images are printed on the sheet S by a recording head 9 reciprocated on a shaft 7.

←→ Problems to be solved by the invention By the way, in the above-mentioned inkjet blink 1a,
Since the image recording surface of the sheet S is cleaned by the adhesive rollers 3, 3 on the upstream side of the platen roller 2,
Dust such as paper powder floating inside the printer may adhere again to the sheet S between the adhesive roller 3 and the recording head 9, and the dust may adhere to the ink ejection opening of the recording/X-rad 9 and clog it. This has the disadvantage that the character quality deteriorates, and the paper fibers become fluffy as the sheet S curves along the platen roller 2, and the fluff of the paper fibers adheres to the ink ejection ports of the recording head 9, resulting in clogging. This has the disadvantage that the quality of characters deteriorates.
