ABSTRACT:
A method of and apparatus for synchronously transferring an original and a sheet of copying paper for electrostatic photoduplication. A paper feeding device feeds the sheets of copying paper one at a time until the front edge reaches a predetermined position at a front edge stop. The sheet of copying paper is held at the predetermined position on standby for a period of time, and then a paper transfer device transfers it to move the front edge to an exposure point. At the same time an original placed on a mount is moved from a stopping point in the cycle of movement of the mount to a position in which the leading edge of the original is at an irradiation point optically aligned with the exposure point. The period of time during which the copying paper is fed from the supply, held in the predetermined position, and then moved to the exposure position is equal to the time for moving the mount for the original from a predetermined point along the path of movement of the mount to the irradiation point. Thereafter, the original is moved past the irradiation point synchronously with transfer of the copying paper past the exposure point at a predetermined rate for exposing the copying paper to the image from the original.
