Abstract: A portable scanner includes a housing, a transmitting path, a scanning unit and a transmission module. The transmitting path longitudinally penetrates through two opposite sides of the housing. One side of the transmitting path forms a first channel, and the other side of the transmitting path forms a second channel. The scanning unit is arranged in the transmitting path and partially projects into the first channel. The transmission module is arranged in the transmitting path and partially projects into the first channel. The transmission module is in contact with the scanning unit. The transmission module includes a transmission roller. The scanning unit and the transmission roller are disposed to two facing sides of the transmitting path along an up-down direction. The scanning unit is disposed on and contacts with the transmission roller in the transmitting path.

Abstract: The present invention relates to a document feeding structure including a feeding path; a scanning unit, said scanning unit being arranged on one side of said feeding path to scan documents passing through said feeding path; a transmitting roller, said transmitting roller arranged opposite to said scanning unit and covering the whole feeding path; and a pressing plate, said pressing plate including a fixed end, a free end disposed in said feeding path to contact with said transmitting roller and an extending portion connecting said free end and said fixed end, wherein said pressing plate covering the whole feeding path.

Abstract: A document feeding mechanism includes a frame, a document picking means positioned in the frame for picking up and conveying a document, a stopper means positioned in the frame for blocking the conveyance of the document, a supporting portion cooperating with the stopper means for supporting the document picking up means while the document picking up means is raised at a predetermined level, and a blocking portion restricting a rotatable angle of the stopper means for blocking the conveyance of the document while the document picking up means is raised at the predetermined level. The document feeding means is kept at the predetermined level via the cooperation of the supporting portion and the stopper means for supporting the document feeding means. Since, the document feeding mechanism has high reliability to resist shake and crash for preventing the document picking up means from being drooped.
