The driving mechanism performs feeding, cutting and rewinding of a roll film using only one driving motor. The driving mechanism includes a series of gears: A(6), B(8), C(9), D(11), E(12), F(14), G(15) and H(16); a sector gear(13) engaged with a small gear(12a) of the E gear(12) and a small gear(14a) of the F gear(14); a driving motor(17) to transmit power to the H gear(16); a power transmitting means for transmitting selectively to the F gear(14) or the H gear(16); and a cutter arm(20) moved by the sector gear(13).
