Abstract

The invention provides a contact type image sensor, an image scanning device and a data processing method of the image scanning device. The contact type image sensor comprises a frame body, a light emitting element, an optical lens, a circuit board, a photoelectric conversion chip and a light receiving element. A plurality of photoelectric conversion chips are arranged, all the photoelectric conversion chips are linearly arranged on the circuit board in multiple rows, the arrangement direction of each row of photoelectric conversion chips is perpendicular to the relative movement direction ofthe scanned object and the photoelectric conversion chips, and the photoelectric conversion chips are electrically connected with the circuit board; a plurality of light receiving elements are arranged on different photoelectric conversion chips, a junction seam is formed between two adjacent photoelectric conversion chips in the same row, and the junction seam in each row of photoelectric conversion chips is arranged corresponding to one or more light receiving elements on the photoelectric conversion chips in the adjacent row. According to the invention, the problem of leakage points in scanning in the prior art is solved.

Description

technical field [0001] The invention relates to the field of industrial detection, in particular to a contact image sensor, an image scanning device and a data processing method thereof. Background technique [0002] As contact image sensors (CIS for short) are more and more widely used, some problems appear in certain application fields. In the field of industrial detection, the photoelectric conversion chips (abbreviated as IC) on the existing CIS are arranged in a line. Due to the physical structure, the joint between the last light-receiving element of the IC in front of each row and the next light-receiving element will be separated. The distance of more than one light-receiving element will lead to missed detection during the scanning process, which will affect the accuracy of scanning. Contents of the invention [0003] The main purpose of the present invention is to provide a contact image sensor, an image scanning device and a data processing method thereof, so a...
