ABSTRACT:
A charge transfer device comprising, photoelectric converting elements arranged along rows and columns, first charge transfer paths to horizontally transfer the charges obtained by those elements, a second charge transfer path to vertically transfer the charges transferred through the first charge transfer paths, and third charge transfer paths to couple the respective charge output parts of the first charge transfer paths and the charge input parts of the second charge transfer path corresponding to the output parts. Each third charge transfer path is connected to the first and second charge transfer paths so as to form almost an obtuse angle to those first and second paths, respectively. In this device, the length in the charge transferring direction of each charge transfer cell can be shortened while keeping the capacity of each cell constant, thereby improving the charge transfer efficiency at the junctions of the first and second charge transfer paths even when the charges are transferred at a high speed.
