Abstract
The present invention relates to a charge transfer device which allows change of the charge transfer direction wherein transfer portions are formed of generally rectangular shape which have a length in the charge transfer direction which gradually gets longer to the transition direction change area and widths which get smaller relative to the direction transverse to the charge transfer direction. The length times width of the transfer portions is made substantially constant. The feature providing that the transfer regions become narrower as they approach the portion of charge direction change allows the charge direction change to be relatively shorter than apparatus of the prior art thus resulting in greater efficiency, shorter charge transfer time, eliminates the requirement for direct current bias and a more integrated device is provided.
