Title: Small-sized original reader
Inventor: SATO MASUJI
IPC: H04N1/04
Filed: 1984-09-26
Abstract: PURPOSE:To utilize effectively luminous amount and to attain sharp reading at high speed by fitting a convex lens to an end face of a focusing rod lens array opposing to the original and fitting a concave lens to an end face opposing to a large-sized image sensor so as to collect the reflected light from the original. CONSTITUTION:The original 1 is moved, a light source 2 is placed on an original face to irradiate the original. The luminous flux subjected to irradiation and reflection as shown in dotted lines on an original face is introduced to a light leading system 13 and it is required for the arrangement of the system 13 close to the original 1 to refract the light for a length equivalent to the conjugate length by a convex lens. Thus, the convex lens 14 is mounted to the end face of the system 13 opposite to the original 1 so that the reflected ray is refracted and led to the system 13. Further, a concave lens 15 is fitted to the end face of the system 13 opposite to the sensor, the ray going straight in the inside of the system 13 is refracted and the image is formed to the sensor 4. Thus, the light reflected on the original is collected efficiently and enters the system and collected again on the sensor, the image is formed, then the brightness efficiency is improved remarkably.
