ABSTRACT:
An image scanner includes a base, a glass plate disposed on the base for receiving a document to be scanned, a transmitting stand disposed in the base and being capable of moving laterally therein, a top shell disposed above the base and engaged with the transmitting stand and an optical sensing unit disposed in the top shell, so that the image scanner can directly scan the document and effectively obviate the optical error problem which occurs when a glass plate is located between a document to be scanned and an image sensor as in the prior art.
