Abstract: An image reading device is activated by the light interference of a light path. The image reading device comprises at least an image sensing element, a picture and an image changing mechanism such as a picture conveying module, picture rotating module, a hole or a soft button with a picture in the inner side. The user may use a finger or other objects to interfere with the image generated in the image sensing element. By detecting the changes of the image, a predetermined activation process of the image reading device is therefore started.

Abstract: The image reading device includes a scanning module and a light interference module. The user may use the light interference module to interfere the light path to trigger the scanning processes from a standby mode. When the light path is interfered, the image sensor would generate different image signal output. In this case, by detecting the difference of image signal output pattern, the image reading device would be triggered to load specific scanning control parameters to perform the scanning, such as starting the scanning programs and driving the scanning module to an initial position for completing the scanning.

Abstract: An alignment pad is set in front of the image sensor. A lens is set between the alignment pad and the image sensor. The alignment pad includes a set of boundary alignment patterns. At least one sets of resolution analysis patterns are formed on the alignment pad. Each set of the resolution analysis pattern includes a horizontal analysis resolution pattern and a vertical resolution analysis pattern. The horizontal analysis resolution pattern is consisted of a plurality of vertical lines to analyze the horizontal resolution of the lens. The vertical resolution analysis pattern is consisted of a plurality of oblique lines to analyze the vertical resolution of the lens. The signals detected by the image sensor is fed to an application specific integrated circuits (ASIC) to generate a collation data. Subsequently, the collation data is fed into a buffer to store the data. A computer is responsive to these signal, and displays the collation data on the monitor in gray mode for collation.

Abstract: An apparatus for sheet feed-out control is provided on an automatic sheet feeder used in conjunction with scanners, fax machines, printers, copiers, and the like. The apparatus comprises a feed-in roller set for feeding the sheet into a scanning position where a scanning process is performed and a feed-out roller set for pulling the sheet away from the scanning position and delivering the sheet onto a receiving tray. A pivotal pressing member is pivotally affixed proximate to the feed-out rollers. The pivotal pressing member is pivotally turned by the sheet as the sheet is being fed out of the feed-out rollers. As the sheet is entirely fed out of the feed-out roller set, the pivotal pressing member presses down against the tail edge of the sheet, thus flipping the sheet off the feed-out roller set. Since the sheet can be placed flat on the receiving tray right after it is entirely fed out of the feed-out roller set, a stack of sheets after being scanned can be piled up neatly on the receiving tray.
