Original conveying apparatus, light amount adjustment method for light-emitting section thereof, image forming apparatus, control method therefor, storage control device, storage control method, and storage medium

Abstract

There is provided an original conveying apparatus for conveying an original to an image reading section of an image forming apparatus, which is capable of preventing the number of times of writing to a nonvolatile storage medium that stores a correction value for the light emission amount of an optical sensor from exceeding a limited number of times even when adjustment of the light emission amount of the optical sensor is carried out frequently, reducing as far as possible the number of times of writing data to the storage medium that can store such data a limited number of times, thereby eliminating the occurrence of inconvenient situations such as it being impossible to maintain proper output processing, and lengthening the lifetime of the storage medium. Writing of the correction value for the light amount of the light-emitting section of the optical sensor to an EEPROM is carried out if the correction value has changed by at least a predetermined amount relative to the value before adjustment but is not carried out if the correction value has not changed by at least this predetermined amount relative to the value before adjustment.
