Abstract:
PURPOSE: To provide an image reader that can read an image with high quality even when an original platen is bent. CONSTITUTION: In the image reader where a CIS (Contact Image Sensor) 1 is pressed by a spring 5 to press a press contact member 2 into contact with a lower face of an original platen glass plate 3, the press contact member 2 is placed with a main scanning read range W of the CIS 1, concretely at a position at which a bent of the original platen glass 3 with respect to both ends of the main scanning read range W is about a half of a maximum bent. Thus, when the original platen glass 3 is bent, the CIS 1 is depressed down against the spring 5 by about a half the maximum bent within the main scanning read range W of the original platen glass 3. Thus, the optimum focal position of the CIS 1 is deviated downward, resulting that the upper face of the original platen glass 3 being the original face is maintained within a valid focal range (focal depth) of the CIS 1 within the entire main scanning read range so as to attain image reading with high quality.
Abstract:
A device and method for use with an image recording device. The device having a background target and a first surface including the background target recessed therein. The device further including a substrate stabilizer configured to move a substrate having an image printed therein in closer proximity to the background target and below the first surface when activated.
Abstract:
A multi-function printer having a compact size and portable configuration while providing printing, scanning and copying functionalities is disclosed. The multi-function printer may include a paper handling assembly- and a floating scanner assembly pivotably coupled to the paper handling assembly. The multi-function printer may further include a printer assembly coupled to the paper handling assembly. The floating scanner assembly is coupled to and aligned with a pick roller portion of the paper handling assembly and configured to can and/or otherwise operate on a media supported within a document feeder. Thus, the multi-function printer may provide a wide variety of functionalities while maintaining a desirable compact configuration and portability.
Abstract:
A scanner capable of scanning a curved surface such as a bottle or other cylindrical, or curved surfaced object. In one class of embodiments, the present innovations include a scan head and one or more rollers (preferably two rollers, one active, the other passive) on which a cylindrical object turns in proximity to the head. As the object turns, the head records the image on the surface of the object.
Abstract:
The passively energized floating guide (1) for a parked head scanner having a scanning glass slit (2). The floating guide (1) applies pressure to the original papers crossing the scanning glass slit (2), to keep it free from contamination. The floating guide (1) comprises a wiper bar (30) which is pivotally mounted above the scanning glass slit (2) such that it extends from a first end to end of the glass slit (2) and rests on it. The weight and pivot point from the wiper bar (30) are chosen such that the force of the original paper rotates the wiper (bar) and the scanning glass slit (2) with sufficient force to clean the glass, but not enough force to jam the paper. After the paper has passed, the wiper bar (30) pivots back to its initial position.

Abstract:
Apparatus for supporting a scanner head, the apparatus comprising: a carrier assembly (12); a bogey assembly (11); and a scanner head assembly (10), comprising a mounting for holding a scanner head; wherein the scanner head assembly and the bogey assembly are both mounted on spring bearings on the carrier assembly such that they can both move in a vertical direction, and the scanner head assembly comprises at least two collinear vertical bearings (14) which restrict movement of the scanner head assembly to vertical movement substantially perpendicular to a document path, and the bogey assembly comprises two laterally spaced bearings (13) which allow rotational movement of the bogey assembly about the scanner head mounting.
