Abstract: An ink jet printer has two first driven rollers (A) disposed at a most upstream position in a secondary scanning direction, two first driven rollers (B) disposed at an intermediate position in the secondary scanning direction, and a single first driven roller (C) disposed at a most downstream position in the secondary scanning direction. The pressing force on a trailing edge of the recording sheet (10) is dividedly released in three steps sequentially and, accordingly, the nipping force and feeding force working on the recording sheet (10) also vary stepwise. Load fluctuations that occur at the moment the trailing edge of the recording sheet (10) is released from the nipping force of the first transport roller (4) also vary stepwise, whereby it is not possible that the feed precision is disturbed in a moment.

Abstract: An object of the invention is to provide a sheet member processing apparatus by which a necessary working space is secured and a workability can be enhanced in doing maintenance. A housing space (32) in which processing means (26) is housed can be opened and closed by displacing a front cover potion (31) relative to a casing (30) of a casing (21). In the casing (21), a document discharge port (35) is formed upper than the front cover section (31). On the front cover section (31) is provided a document discharge tray (24) which receives a discharged document. When the cover section (31) is made to be displaced relative to the casing main body (30), the document discharge tray (24) is displaced together with the front cover section (31). This makes it possible to secure the large working space and enhance the workability, for instance, when an operator replaces consumable articles such as an ink cartridge (53).

Abstract: An object of the invention is to provide a sheet feeding apparatus of a simple structure which is capable of stacking discharged sheets in a discharged-sheet stacker in an aligned manner without performing any complicated operation even when the sheet size is changed. The common sheet guide is removably attached to the cassette and comes in contact with the sheets stacked in the cassette and the sheets stacked in the stacker. When the sheets in the cassette are replaced with sheets of a different size, as the common sheet guide is moved to come in contact with the edges of the sheets, the common sheet guide is located at the position capable of coming in contact with the edges of the sheets stacked in the stacker. Therefore, it is possible to restrict the movement of the sheets stacked in the stacker and to align the sheets with each other.

Abstract: An image-reading method which allows a transporting motor to transport, relative to each other, an original document having an image to be read and a light-receiving element for scanning the image in the width direction, so as to read the image in a direction that is orthogonal to the width direction. The method allows the light-receiving element to read the image and output the resulting image data. The transporting speed of the transporting motor is increased based on the desired suppression in the resolution of the image data. Therefore, a facsimile machine using the above-mentioned method can read the image of an original document with a desired resolution.
