PURPOSE:To successively and rapidly copy continuous image frames on both the sides of copying form by successively copying at every other frames of the continuous image frames of an information recording medium on the 1st surface of the copying form and then successively copying the remaining image frames on the 2nd surface of the copying form. CONSTITUTION:A microfilm F is sent to an image frame 3b adjacent to the frame 3a finally copied on the 1st surface and then copying to the 2nd surface is executed from the copying form P set up on the uppermost position of an intermediate tray 22. Provided that when the number of image frames to be copied is an even number, i.e. the image frame finally copied on the 1st surface is equal to the final frame, the copying form copied by the final frame and set up on the uppermost position of the intermediate tray is discharged as it is without copying to its 2nd surface and the copying to the 2nd surface is executed from the next copying form P. To transfer copying from the 1st surface to the 2nd surface, the frame may be moved only by one frame. Consequently, continuous image frames can be rapidly copied on both the sides of the copying form within a short period. |
