Abstract

PURPOSE:To eliminate the vertical fluctuation of a transmitting original to stabilize the reading of an optical signal and thus reproduce a high-quality picture, by forming the optical fiber bundle receiving surface into a curved surface in a facsimile transmitter. CONSTITUTION:The receiving surface 4a of the optical fiber bundle 4 is formed into a curved surface, and the bundle 4 is formed so as to form a focus on the transmitting original. As a result, the discontinuous property can be improved for the surface 4a at the contact part to the original. Thus the vertical fluctuation can be eliminated for the original. The same effect is secured if the surface 4a is formed into an arc or a polygon.
