Image reading system using an interruption of a pulse train to adjust a scanning period

U.S. Patent Number: 5381244

Abstract: An image reading system including a charge storing type image sensor drives a manuscript or an image sensor in accordance with a driving pulse from a driving unit. A speed of the driving pulse from the driving unit is determined by a speed setting unit, depending on a change of a period of the apparatus scan. The driving pulse is stopped for a certain period of time, so that the difference in a speed of the driving pulse between the different apparatus scan periods is decreased.
