Abstract

The invention provides an image scanning device, and the device comprises a lens assembly which comprises a plurality of lenses, wherein the plurality of lenses are sequentially arranged in a scanningdirection, and the scanning direction is the length direction of a target object; one photoelectric conversion chip, wherein the chip and lens assemblies are oppositely arranged in a spaced mode in the first preset direction; Multiple imaging areas are arranged in the scanning direction of an image scanning device. The number of imaging areas is the same as that of the lenses. Any two adjacent imaging areas are at least connected; the first preset direction is the extending direction of the optical axes of the plurality of lenses; seamless scanning of the image scanning device is realized; compared with a plurality of area-array cameras in the prior art, the distance between the photoelectric conversion chip and the lens in the first preset direction can be relatively small, so that the reduction multiple of a scanned image does not need to be increased, and any two adjacent imaging areas can be ensured to be at least connected, namely, the device ensures that the resolution of the scanned image is relatively high while seamless scanning is realized.

Description

technical field [0001] The present application relates to sensor technology, in particular, to an image scanning device. Background technique [0002] When the existing area scan image scanning device scans an image, it becomes an image smaller than the original document. Although the scanning device can be arranged side by side by cameras, it can realize long-distance scanning. However, the size of the existing cameras is too large, and the distance between two or more cameras is too far. To ensure seamless scanning, the reduction factor of the object will become very large, and high-resolution scanning cannot be achieved. The cameras are close to each other. Although the reduction factor of the object becomes smaller and high-resolution scanning is possible, due to the size limitation of the camera itself, it cannot be infinitely close together, and seamless scanning cannot be achieved. Therefore, there is a need for a high-resolution seamless scanning device. [0003] ...
