Image reader

Abstract

Abstract <P>PROBLEM TO BE SOLVED: To improve reading productivity of images on the surface and rear face in an image reader for reading images on both faces of an original manuscript with one-time transfer of the original manuscript. <P>SOLUTION: The image reader has a CCD image sensor 78 for reading an image on a first face of each original manuscript to be transferred, and a CIS 50 for reading an image on a second face of each original manuscript. Surface image data of n-th (n: an integer) original manuscript read by the CCD image sensor 78 are outputted, second-face image data of (n-1)-th original manuscript read by the CIS 50 and stored in a page memory are outputted, surface image data of (n+1)-th original manuscript read by the CCD image sensor 78 are outputted, and second-face image data of the n-th original manuscript read by the CIS 50 and stored in the page memory are outputted in a first mode in which the CCD image sensor 78 starts surface reading of the n-th original manuscript during rear-face reading of the n-1-th original manuscript by the CIS 50. <P>COPYRIGHT: (C)2008,JPO&INPIT
