Problems solved by technology

[0008] 1. It only has the function of single-sided scanning: traditional flatbed scanners are designed for single-sided scanning of documents, but cannot be used for double-sided scanning.
[0009] 2. If you are engaged in double-sided scanning, it will take more time: double-sided scanning is equivalent to scanning two documents. After the document is scanned once, take out the document and scan the other side of the document again, which will take twice the scanning time

Embodiment Construction

[0021] The scanner with double-sided scanning function provided by the present invention is characterized in that it can simultaneously perform double-sided scanning of documents to be scanned. Traditional flatbed scanners can only be used for single-sided scanning. If you want to do double-sided scanning of documents, you must scan the documents a second time, which is laborious and time-consuming. In the scanner with double-sided scanning function of the present invention, a group of lower optical machines are arranged in the casing under the light-transmitting flat plate of the scanner. The lower optical engine contains a set of image sensor components. On the upper side of the light-transmitting flat plate, a document holder capable of erecting documents to be scanned and two sets of upper optical machines located on both sides of the document surface are arranged. The two groups of upper optical machines respectively have a light source device and a reflector. The ligh...

Abstract

A scanner with double face scanning function, used for scanning first face and second face of the file, comprises chassis, transmit plate and underpart optical mechanical device. The chassis has an opening part,the transmit plate is positioned at the opening part. The underpart optical mechanical device is positioned in the chassis in the chassis under the transmit plate. The underpart optical mechanical device also has a image sensible head. The scanner at least includes: a file holder positioned above the transmit plate used for fixing the file and making the file positioning above the transmit plate with upright state. The first upside optical mechanical device is positioned at the one side of first face above the transmit plate, used for scanning the first face; the second upside optical mechanical device is positioned at the second face above the transmit plate, used for scanning the second face.

Description

technical field [0001] The present invention relates to a scanner with double-sided scanning function, in particular to a scanner with double-sided function for scanning the first side and the second side of a first document to be scanned. Background technique [0002] Among the many peripherals of a personal computer, a scanner can be said to be one of the basic equipment. Most common flatbed scanners can only be used for single-sided scanning of documents. Therefore, scanners with double-sided scanning functions have become an important item in research and development. [0003] refer to figure 1 , which is a schematic diagram representing a conventional flatbed scanner. The flatbed scanner 100 has a casing 110, on which is a light-transmitting flat panel 120 for placing documents to be scanned (not shown in the figure), and inside the casing 110 is provided with a lower chassis 130, A light source device 140 is disposed above the lower light engine 130 . The flatbed s...
