Abstract
PURPOSE: To realize the improvement of pring condition at the reception side by ensuring the reading-in through the use of the drum with surface treatment so that the shape of cross section is a polygon and the concentration of reflection at each surface is different.
CONSTITUTION: On one surface of the drum 7 on which the surface treatment is made so that the shape of cross section is a polygon and the respective surface has different concentration of reflection, light scanning is made on the original 1 and light signal is inputted to the image sensor 6. Further, the light signal is converted into an electric signal to be transmitted to the reception side as the video signal. Accordingly, to the original having the width of read-in smaller than the width of read-in for the original base paper, since the automatic black and white judgement level is made to the concentration of reflection at the surface of the drum 7 opposing to the image sensor 6, one surface of the drum 7 suitable for the drum 7 is selected to the original 1 and it is opposed to the image sensor 6, allowing to ensure the read-in for the transmission on the surface.
