インイメージセンサ−０The information is read when the reflected light from the information recorded on the form passes through a light-receiving window made of a transparent member and reaches a cell, and the light-receiving window is a slit-shaped window located directly above the cell. A light-blocking part is provided on at least one side of the light-receiving window for forming the slit, so that only the light that passes through the window part of the slit is received by the cell, and the excess light other than the window part is blocked by the light-blocking part.
