Structure of scanner core

Abstract

This invention provides one scanner center structure, which comprises the following parts: shell set with first and second open tanks and with first light source into first tank and second light source to the second tank inside; first lens down the first tank and second lens down second tank; active lens; lens set; lens probe and light sensor elements. This invention can realize switching light path design through double light sources.

Description

technical field [0001] The invention relates to a movement structure of a scanner, in particular to a movement structure with dual light sources and switchable light paths. Background technique [0002] When a user is scanning a large number of manuscripts, a flatbed scanner that can only scan one manuscript at a time cannot meet the needs of the user. Therefore, a scanner that can be matched with an automatic document feeder (ADF) to perform flatbed scanning as shown in FIG. 1A and also perform sheet-feeding scanning as shown in FIG. 1B has become a mainstream scanner at present. [0003] Continue to refer to Fig. 1A and Fig. 1B, but the common scanner 1 still adopts the same movement structure 10 as the flatbed scanner, so when it is necessary to perform paper-fed scanning, the movement structure 10 must be completely moved to Scanning can only be performed under the scanning window 11. Unavoidably, some placement space 12 must be reserved in the scanner 1 to place the mo...

[0003] Continue to refer to FIG. 1A and FIG. 1B , but the common scanner 1 still adopts the same movement structure 10 as the flatbed scanner, so when it is necessary to perform paper-fed scanning, the movement structure 10 must be completely moved to Scanning can only be performed under the scanning window 11. Unavoidably, some placement space 12 must be reserved in the scanner 1 to place the movement structure 10 for paper-fed scanning, thus increasing the volume of the entire scanner 1.
