ABSTRACT:
A converter for converting a reflection type scanner to a transparence type scanner comprising a casing equipped with a window through which light beams for transparence type scanning may pass. Inside the casing at the area of the window is a light distribution plate to transmit and to distribute incidence light beams to all areas of the light distribution plate. At both sides of the window are two light incidence windows through which incidence light beams may pass. Inside the casing at the area of the incidence windows are two reflecting mirrors to reflect the incidence light beams to at least an edge surface of the light distribution plate whereby the incidence light beams enter the light distribution plate and are distributed to the whole area of the light distribution plate. A control device and a noise minimizing device positioned in a reflection type scanner is also disclosed in this invention.
