PURPOSE:To attempt the miniaturization of the device and the speedup of copying speed by providing the scanning optical separately from the transfer paper transport unit, and compensating the difference of its stroke length for the difference of shift speed. CONSTITUTION:Wire 18a which runs optical system 1 and wire 18b which runs transfer paper transport 7 are driven by two-step pulleys 19a, 19b which have a certain rotation ratio, respectively, hence the transfer transport 7 driven by the pulley 19b having a large diameter runs faster than the optical system 1. Therefore, at the same time when the optical system 1 starts its scanning in the direction of A to charge the photoreceptor 11 so as to form latent image and the system 1 reaches the left end, the transfer paper transport 7 comes up with this end so as to place the transfer paper on the photoreceptor 11. Subsequently, with the return of the transport 7 in the direction of B, the latent image on the photoreceptor 11 is transferred on the transfer paper, visualized and fixed. And the optical system 1 and the transport 7 return to the original positions at the same time. |
