Abstract: A hidden document-covering device for a scanner, especially for a scanner built in the case of a computer in which a device is used for holding the document on a moving tray during scanning process. The document-covering device always hides itself in the case even when the tray moves out. During the scanning process, the document for scanning is firmly pressed onto the tray to prevent from curling or sliding. After scanning, i.e. when the tray moving out, the document-covering device will release the document for easy loading and unloading.

Abstract: A sheet-feed type scanner including a scanner base defining a scanning plane and having a document feed hole at one end into which document to be scanned is inserted; an image pick-up mechanism fixedly mounted in the scanner base and comprised of a light source, a reflector, a focus lens and an image sensor, and adapted to pick up image of inserted document within the scanning plane and to convert detected image signal into corresponding electrical signal; a document sheathe adapted for holding document for scanning, the document sheathe having a first flat sheet member and a second flat sheet member connected together for holding document in there between in a flat manner for scanning; and a transmission mechanism controlled to move the document sheathe along the scanning plane, for permitting document to be scanned by the image pick-up mechanism; and a document guide adapted for guiding the document sheathe through the scanning plane.

Abstract: A window arrangement including a scanning area in a scanner through which document is moved and scanned; a window mounted in the scanning area through which scanning light passes onto document to be scanned; a locating device adapted to hold the window in the scanning area; and a pick-up device fastened to one end of the window through which the window can be pulled away from the locating device out of the scanning area for a maintenance work.

Abstract: An improved document tray for scanners includes a supporting part and covering means. The supporting part is used to hold a document for scanning and the covering means is used to press and fix the document. The covering members does not need to be opened for inserting a document into the supporting part. The document tray of the invention indeed improves the drawbacks of the prior art so that the tray will not jam or be damaged when it is pushed into the scanner.
