Image scanner with a function of initiating scanning automatically
First Claim
1. An image scanner with a function of initiating scanning automatically, wherein a sensing window is provided in front of a scanning start position of a document window of said image scanner, and an additional independent light source is provided below said sensing window, thereby to cooperate with CCD/CIS (charge-coupled device/contact image sensor) on the optical carriage of said image scanner to detect the open/close status of a top cover of said image scanner, a specific pattern of the portion of said top cover corresponding to said sensing window can not be all black, so as to determine to automatically initiate scanning of said image scanner or not.

Abstract
This relates to an image scanner with a function of initiating scanning automatically. In addition to the main light source, an independent light source is provided in an image scanner for supplying a specific light signal, and a corresponding sensing window is also provided for detecting the open/close status of the top cover by means of the existing CCD/CIS in the image scanner, and decide the scanning of the document automatically or not accordingly. The independent light source being provided can be lighted on continually or be flickering for cooperating with the sensing window for detecting the open/close status of the top cover.
