Double-sided synchronous scanning device and double-sided synchronous scanner

Abstract

The present invention discloses a double-sided synchronous scanning device. A scanning channel is formed between two scanning components; two backlight plates are respectively used to provide backlight for an opposite-side scanning component and fixed with the same-side scanning component; one side of each backlight plate facing the scanning channel is provided with a light guide groove corresponding to a light inlet of the corresponding scanning component; a backlight source is arranged in the light guide groove. When the two scanning components work synchronously, because the backlight plates always need to provide backlight for the opposite-side scanning component, and the reflected light generated by the backlight plates on a scanned sample enters the light inlet of the same-side scanning component, which will affect the image scanning effect.
