Its structure generally includes a bottom plate for placing documents, a support frame is arranged on one side of the bottom plate, and a scanning lens for scanning and photographing document content is installed at the upper end of the support frame.
[0003] According to actual operation experience, the accuracy of horizontal scanning is higher. However, in fact, the surface to be scanned of the object to be scanned and stably placed under the scanning camera is not always horizontal. For example, for a tripod, a T-shaped display board or a bracket, etc., the surface to be scanned is mostly inclined after being stably placed, which will lead to a decrease in scanning accuracy. Therefore, it is necessary to develop a new type of high-speed document scanner that can solve the above problems. Summary of the Utility Model
