ABSTRACT:
The image reading device scans film images on photographic film by a CCD line sensor, and transfers image data, which are read out from the CCD line sensor, to an external image receiving device via a line buffer. If a data receiving side comes into a busy state and the data cannot be transferred for some time, the line buffer overflows. When an overflow detecting section detects the overflow, the writing of the image data in the line buffer is stopped, so that the film images can be scanned again. While the film images are scanned again, a communication controller detects image data corresponding to the image data when the overflow is detected, so that the writing of the image data in the line buffer can be resumed from a point when the correspondence is detected.
