Abstract
A curl straightening device for removing a curl from a paper sheet which is caused during printing by a printer. The curl straightening device includes a supporting platen which supports a curled paper sheet after printing is performed on a first surface of the paper sheet, a carriage which is reciprocatingly movable along the supporting platen, and a pressing member, mounted on the carriage and positioned on an opposite side of the paper sheet from the platen. The pressing member presses against a second surface of the paper sheet as the carriage moves along the platen so as to remove the curl from the paper sheet which is caused by printing on the first surface of the paper sheet.
Claims8
A printer comprising:
- a print head located at a print position along a paper feed path along which a paper sheet is conveyed in a paper moving direction such that printing by the print head is applied to a first surface of the paper sheet;
- and
- a curl straightening device located adjacent the paper feed path at a downstream side of the moving direction of said paper sheet relative to the print position, the curl straightening device including:
- a supporting platen which supports the paper sheet such that the supporting platen contacts the first surface of the paper sheet;
- a carriage which is reciprocatively movable along the supporting platen;
- and
- a pressing member, provided on the carriage opposite to the platen and positioned to press against a second surface of the paper sheet as the carriage is reciprocated, thereby removing curl from the paper sheet caused by printing on the first surface of the paper sheet.
A curl straightening device comprising:
- a supporting platen which supports a curled paper sheet after printing is performed on a first surface of the paper sheet;
- a carriage which is reciprocatingly movable along said supporting platen;
- and
- a pressing member, provided on said carriage oppositely of said platen, which presses against a second surface of the paper sheet as said carriage moves so as to remove the curl of said paper sheet caused by printing on the first surface of the paper sheet.
A printer for printing on a paper sheet, the printer comprising:
- a first platen;
- a first carriage which is reciprocatively movable along the first platen;
- a print head mounted on the first carriage;
- a second platen;
- a second carriage which is reciprocatively movable along the second platen;
- a pressing member mounted on the second carriage;
- and
- a paper feed path for guiding the paper sheet between the first platen and the first carriage such that printing by the print head is applied to a first surface of the paper sheet, and for guiding the paper sheet between the second platen and the second carriage such that the pressing member presses against a second surface of the paper sheet, the second surface being located on an opposite side of the paper sheet from the first surface.
