<p>PURPOSE:To make image forming larger than paper size easy by feeding two sheets of paper from two paper feeding sections at timing that superposes a fixed length and thereby copying one picture image continuously in two sheets of paper. CONSTITUTION:A double feeding copying mode is set from an original, magnification of copying and length of the paper, and paper is drawn out by upper and lower rollers 16, 17. When the rear end of upper paper 2a is detected by a sensor 6, the first timer starts and timing is measured to superpose on the lower side paper by specified length. The front end of the paper 3a is detected by a sensor 7, and copying of set number of sheets is performed raising copying voltage during specified superposition with the upper side paper 2a. Accordingly, picture images are copied overlapped without break, and superposed part is closely adhered due to heat and pressure received at the time of transferring. Consequently, it is not necessary to make positioning again after the paper is discharged, and a picture image larger than maximum paper size for image forming can be formed easily.</p> |
