Abstract: A platen gap adjustment assembly for a printing apparatus including a printer using the platen gap adjustment assembly to adjust the platen gap between a platen and a print head when printing on a print medium transported between the platen and the print head. The platen gap adjustment assembly includes a guide shaft, which slidably supports a carriage carrying the print head and a pair of mounting members each supporting the guide shaft. The mounting members have positioning engagement parts for holding or maintaining the position of an eccentric shaft in a given position which controls the position of the positioning engagement parts relative to the mounting members. An urging member urges one of the mounting members with the guide shaft fit therein in the direction for causing the positioning engagement parts into one of a given set of positions.

Abstract: A media processing device can convey checks at a constant speed passed an information reading position without slipping and without increasing the relay capacity of the transportation roller. The check processing device 1 has two transportation rollers 31 and 32 between the scanning position 52A of the contact image scanner 52 and the separation roller 17 and retard roller 18 that produce a transportation load or transportation load variation. The upstream-side transportation roller 31 turns faster than the downstream transportation roller 32 so that the checks 4 are fed with slack between these transportation rollers 31 and 32. Because of this slack in the part 402 of the check 4 between the transportation rollers 31 and 32, the transportation load from the separation mechanism does not act on the downstream transportation roller 32.

Abstract: The medium conveying mechanism includes a motor, a driving pulley adapted to be rotated by the motor, an endless belt wound around the driving pulley and adapted to be moved by the driving pulley in a belt moving direction, a first driven pulley around which the endless belt is wound and adapted to be rotated by the endless belt, a first conveying roller disposed on the medium conveying path and adapted to be rotated by the first driven pulley to convey the medium, and a first pressure roller disposed to correspond to the first conveying roller so as to press the medium against the first conveying roller. A distance in the medium conveying path between the information reading position and a nip portion between the first conveying roller and the first pressure roller is shorter than a distance between a leading end of the conveyed medium and back end of the recording area. The first driven pulley is disposed upstream from the driving pulley in the belt moving direction.

Abstract: Swinging open the upstream-side cover part (31) and downstream-side cover part (32) of the check scanning apparatus (1) on a common support pivot (33) opens a U-shaped check transportation path (5). The check transportation path (5) can be opened with a simple single-action operation to remove checks (4) jammed in the check transportation path (5) and for maintenance of the magnetic head (84) and contact image sensors (82 and 83). When the task is completed, the open check transportation path (5) can also be returned to the original closed position by a simple single-action operation. If only those parts that require maintenance are exposed when the check transportation path is open, tasks that require opening the transportation path can be done without damaging other parts and without soiling the operator's fingers.

Abstract: Scanning errors and document feed errors are prevented by pressing originals, including thin originals and thick originals of greatly different thicknesses, to the scanning surface (1a) of an image sensor (1) with pressure appropriate for the respective original. A pressure-generating mechanism (50) is used to press the original against the scanning surface (1a) by selecting different elastic bodies with different spring forces to produce a different elastic force in accordance with the thickness of the original document.

Abstract: A print media processing apparatus having scanner feed rollers for holding and transporting print media against an image scanner appropriately controls the scanner feed roller position. The scanner feed rollers are opposite the image scanner, which is disposed along a vertical segment of a transportation path along which a check or form is transported. A roller retraction mechanism moves the scanner feed rollers between a closed position in which the rollers press against the scanning surface, and an open position in which the rollers are retracted therefrom. The scanner feed rollers retract to the open position a specific time after scanning ends. By delaying retraction of the rollers in this manner, the present invention solves the problem of a check or other print media, after having been processed and transported to the exit side of the rollers, from slipping down between the rollers and the image scanner into the vertical transportation path because the rollers opened as soon as scanning ends.

Abstract: A media transportation mechanism comprising a first transportation roller pair and second transportation roller pair disposed in the transportation path on the upstream and downstream sides, respectively, of image scanners convey a slip over a sliding guide surface. The first transportation roller pair produces a feed force towards the sliding guide surface so as to push the leading end edge of the slip to the sliding guide surface. The second transportation roller pair produces a feed force in the direction away from the sliding guide surface so as to push the trailing end edge of the slip to the sliding guide surface.
