Image reading device and system

Abstract

The invention discloses an image reading device and system. The image reading device comprises a light transmitting plate, a first light source, a second light source, a lens, a photovoltaic conversion chip and a data processing circuit, wherein the light transmitting plate is used for carrying an original pattern, the light entering side of the lens is arranged corresponding to the light transmitting plate, the lens is used for receiving stimulation light of the original pattern under irradiation of the first light source and receiving reflected light of the original pattern under irradiation of the second light source, the photovoltaic conversion chip is arranged on the light outgoing side of the lens and provided with a first light sensing pixel line and a second light sensing pixel line, and the data processing circuit is connected with the photovoltaic conversion chip and used for receiving a first-way signal output by the first light sensing pixel line and a second-way signal output by the second light sensing pixel line and used for splitting the second-way signal into a first signal, a second signal, a third signal and a fourth signal. By means of the image reading device and system, the problem that an image reading device in the prior art cannot effectively read images in the original pattern is solved, and the effects of greatly improving the reading function of the image reading device and simplifying the image reading processes are further achieved.
