Picture reader

Abstract

Abstract PURPOSE:To read a larger original as keeping the reading accuracy of a two-dimensional sensor optimum by reading successively the respective part of the original by a single two-dimensional sensor, and composing the picture of the whole original by synthesizing plural read data. CONSTITUTION:The original 1 is placed on an original platen 2, and is irradiated from below by a light source 3, and the light reflected by the original 1 is led to the two-dimensional sensor 7 through a through hole plate 2-1, a color wheel 4-1, a lens 5 and a mirror 6, and an image detected by the sensor 7 is outputted to a memory 8. At this time, a partial read control means 13 revolves and controls the mirror 6 adequately so that the original platen 2 is successively reflected on the sensor 7 as being divided, and stores the pictures of respective divided areas in the respective divided areas 8-1-8-n. Afterward, an overlapped part between the respective divided areas is pattern-recognition-processed by a joint part processing means 9, and one picture of one original is obtained and stored in a memory file 12.
