ABSTRACT:
In a method of controlling the sub-scanning of a document reading apparatus the speed, acceleration or deceleration of the reading section is controlled according to the amount of information stored in a buffer memory which temporarily stores information read by the reading section. The values of the movement speeds, accelerations and decelerations are predetermined according to the stored information amount of the buffer memory and at the time of controlling the reading section, one of these values is selected according to the currently stored information amount of the buffer memory. Whereby any vibration in a reading section is prevented to eliminate the irregularity in the sub-scanning of the reading section.
