Abstract

PURPOSE:To miniaturize the titled reader by placing a sheet original onto a rear face, guiding the original to a carrier means and providing an original cover covering the original on a platen at the middle face so as to use a common read system for a sheet original and a book original. CONSTITUTION:When a book type original 2 is placed on a glass plate 1, the light of a halogen lamp 3 radiates the original 2 through an original cover 5 to apply exosure scanning. Then the image of original is reflected onto mirrors m1-m5 and read by a solid-state image pickup element 4. On the other hand, in placing a sheet original 2a onto the cover 5, the lamp 3 and the mirrors m1-m3 are placed at a prescribed position near rollers 6a, 6b, which clip the original 2a and drive it in the direction B. Then the original 2a is fed toward the direction C, the lamp 3 radiates the original 2a, then the light applies exposure scanning to the entire face of the original 2a. Then the original picture is reflected onto the mirrors m1-m5 and read by the element 4.
