Summary of the invention
Main purpose of the present utility model is the scanner that provides a kind of tool to penetrate the original text scan function at the defective that above-mentioned prior art exists, and that can realize paper feeding scanner penetrates the original text scan function.
Another purpose of the present utility model is the scanner that provides a kind of tool to penetrate the original text scan function at the defective that above-mentioned prior art exists, and can reduce penetrating the area that original text scans required light source module.
Another purpose of the present utility model is the scanner that provides a kind of tool to penetrate the original text scan function at the defective that above-mentioned prior art exists, and can realize that paper feeding scanner is to the not bent scanning that penetrates contribution and reflection contribution.
For reaching above-mentioned main purpose, the scanner that the utility model provides a kind of tool to penetrate the original text scan function comprises the scanning housing, and scanning housing upper surface is provided with the scanning window, inner sweep mechanism, the affixed paper feed housing in top laid.Sweep mechanism comprises reflection original text scanning light source, light connecting gear and image induction element; The paper feed enclosure interior is provided with paper feed mechanism and penetrates the original text scanning light source, wherein, paper feed mechanism is used to transmit the outside and penetrates contribution or reflection contribution, penetrate the original text scanning light source and be positioned at described scanning window top, penetrate original text scanning light source emission light and penetrate contribution with transmission by the outside that described paper feed mechanism transmits, this light also is sent on the light connecting gear and image induction element of described sweep mechanism successively.
For reaching above-mentioned another purpose, the utility model provides a kind of tool to penetrate the scanner of original text scan function, wherein this paper feed mechanism has a pressing plate, be positioned at the scanning window top of described scanning housing, this middle part, pressing plate bottom surface upwards is recessed to form an alcove, and the described original text scanning light source that penetrates is fixedly arranged in this alcove.
For reaching above-mentioned another purpose, the utility model provides a kind of tool to penetrate the scanner of original text scan function, this paper feed mechanism has a pallet and a pallet transmission mechanism, this pallet is positioned at described scanning housing upper surface top, be used to carry the outside and penetrate contribution or reflection contribution, this pallet transmission mechanism is used for pallet is back and forth transmitted along described scanning housing upper surface level.
As mentioned above, the scanner that the utility model tool penetrates the original text scan function comes transmission to penetrate contribution by the outside that described paper feed mechanism transmits by the original text scanning light source emission light that penetrates that is laid in the paper feed housing and be positioned at described scanning window top, and that realizes paper feeding scanner thus penetrates the original text scan function; Be fixedly arranged on the alcove of described pressing plate bottom by penetrating the original text scanning light source, penetrate the area that original text scans required light source module, with the uniformity that guarantees light source and reduce production costs thereby reduce; By pallet the transmission of bent contribution is not realized that paper feeding scanner is to the not scanning of bent contribution.
