Title: Image reading device, image forming device and their control methods
Inventor: NISHIMURA HIROYUKI
IPC: H04N1/113
Filed: 1995-03-23
Abstract: PURPOSE: To provide an image reading device, an image forming device and their control methods which can shorten the image reading time and the image forming time while carrying out the sure correction of image signals. CONSTITUTION: A black reference plate 4 and a white reference plate 5 are arranged in a non-original placing area of an original platen 2. The output of a CCD sensor is stored as the reference value for correction when an exposure lamp 41 is corresponding to the non-original placing area. When the lamp 41 is corresponding to an original placing area, the shading correction is applied to the output of the CCD sensor based on the stored reference value. Thus a reading signal is obtained. In a continuous original reading mode when plural sheets of originals are continuously read, the shift start position of the lamp 41 is set at a point ahead of at least the corresponding position to the plate 4 for the first sheet of originals. Then the lamp 41 is shifted in its moving direction up to the corresponding position to the plate 5 for the second and following sheets of originals.
