Abstract: Ridges and grooves are alternately formed on a platen in the direction of transporting sheets. Wave holding spurs are rotatably supported by torsion springs downstream of a recording area, and pressed against the grooves. Sheet discharge roller pairs are disposed generally downstream from the grooves. Recording sheets exhibit cockling which rises up toward a recording head due to swelling from ink, but a substantial amount of the swelling is contained in the grooves, so the cockling does not come into contact with the recording head, and further, the peak-to-peak distance of the wave shapes of the recording sheets can be reduced. Following the leading edge of a recording sheet passing the sheet discharge roller pairs, the crests of the cockling are collapsed by transporting spurs and divided between wave holding spurs and the transporting spurs, and thus the peak-to-peak distance is further reduced, consequently preventing off-target landing of ink droplets.

The supporting member is arranged in a position corresponding to a convex portion near each of both end portions of the recording medium formed in the shape having the corrugated irregularities with respect to the conveying direction.

Abstract: A printer includes a housing defining a media feed portion and a media eject port, the housing being adapted to house a print engine for printing onto recording media. Included in the printer is a base slideably receivable in the housing at a position laterally distanced from the media eject port, the base having at least a pair of recesses extending in a sliding direction of the base. A pair of flaps are included in the printer, each of which has at least one width portion corresponding to the lateral distance between the base and the eject port. Each flap is hinged into a corresponding recess of the base and is biased in an upward direction via a spring which provides for angular motion of the flap relative to the base. Upon sliding action of the base out of the housing, the flaps are biased upward out of the recesses to a height corresponding to the position of the media eject port.

Abstract: The collecting tray of a ink-jet printer is equipped with a guard to prevent the paper immediately after exiting from the printer to fall to the bottom of the tray. The guard is much narrower than the width of the tray so that the guard tilts the paper. A succeeding sheet of paper pushes the tilted paper until the tilted paper is pushed beyond the end of the guard and falls to the bottom of the tray after a time delay for the ink to dry.

Abstract: An ink jet recording apparatus using an ink jet recording head for recording by discharging ink onto a recording medium arranged in a recording area includes a device for feeding the recording medium. The feeding device is arranged along the recording area and is provided with a mechanism to provide an irregular configuration of the recording medium in the direction intersecting the feeding direction thereof. This minimizes each individual cockling that may take place due to the permeation of ink into the recording medium when images are recorded thereon by the ink jet recording apparatus, and also, orientates the cockling downward reliably in order to prevent the recording medium from being in contact with the recording head to obtain a good quality of recorded images.

Abstract: A printer mechanism to control pen-to-print medium spacing during printing is described. The preferred embodiment of the mechanism includes a printhead and an adjacent platen, the printhead and the platen defining a print zone therebetween. The platen includes ribs adapted for contacting a lower surface of the print medium such that the print medium bends downwardly between the ribs, thereby reducing uncontrolled bending of the print medium in the print zone. The ribs preferably extend parallel to a direction of travel of the print medium and may be positioned adjacent a transition zone, the transition zone facilitating a smooth transition of a leading edge of the print medium onto the ribs.

Abstract: A thermal printer having a main shaft supporting a carriage mounted with printing mechanisms including a printing head and an ink ribbon peeling member for peeling an ink ribbon off the recording sheet as the carriage travels, and fixedly provided with sheet feeding rollers for feeding a recording sheet. The carriage is moved along the main shaft for printing operation to print information on the recording sheet on a line. Before beginning a new line, the carriage is returned to the starting position while the main shaft is rotated to feed the recording sheet. Thus, the main shaft functions as both a guide shaft for guiding the carriage and a sheet feeding shaft for feeding the recording sheet, and thereby the construction of the thermal printer is simplified and the number of the components is reduced.

Abstract: A printer having a fan folded output is provided with an output catching tray which cantilevers upwardly at an angle of 35.degree.-55.degree. from the printer output. The tray includes side walls defining a bottom which bears on the top of the printer. The sidewalls each define integrally formed hooks for catching onto the printer at any bar of fastening disposed in the area of the output. These books enable the cantilevered support to occur. At the bottom of the tray, an arcuate and cam-like surface is disposed against the printer output. This cam-like surface takes horizontal output from the printer and causes it to pass upwardly over its surface. The cam surface extends from an angle in the range of 45.degree. in vicinity of the printer to a slope beyond horizontal at the bottom of the paper catching tray. The end of the cam and the bottom of the paper catching tray form a notch.

Abstract: A deposit container for printers for the deposition of sheet-like data carriers which are delivered by means of a platen is pivotably disposed above the platen to permit selective sheet stacking in upwards or downwards sequence. A pair of transport rollers are arranged adjacent the accepting end opening of the deposit container to be spread apart during sheet introduction into the container and to be moved together to form a drive nip for the sheet after it has passed through the printing zone and lift it into the deposit container. Pivotal flap valves are mounted on the container walls, which are adjusted in dependence upon the pivot position of the deposit container to assist the deposition of the individual sheets.

Abstract: A curvilinear, semi-rigid paper guide for a bi-directional line printer mounted on a platen which provides a surface that bears against the moving print head as the print medium passes between the print head and the paper guide is disclosed. By adjusting the curvature of the paper guide, differences in the distances between adjacent drive sprockets of upper and lower print medium drive mechanisms may be compensated for thus ensuring the printing of straight, parallel and unskewed character lines. In addition, the present invention may be used in a line printer having a single print medium drive mechanism to compensate for nonlinearities in and non-parallelism between the surface of the platen and print head movement.
