PURPOSE:To easily adjust the position of an image on the front and reverse side with accuracy at rapid tempo by controlling the rotary value of a rubber barrel, plate barrel, etc. through the intermediary of a clutch and brake mechanism in an input part where a necessary image movement value is input. CONSTITUTION:A gear 2b on a front rubber barrel 2 which is freely attached/detached by means of a clutch 13, a gear 3b on a reverse side rubber barrel 3 which is freely attached/detached by means of a clutch 14 and a gear 4a fixed on a reverse side plate barrel 4 are caused to sequentially be intermeshed. In the meantime, a motor 32 is freely attached/detached to the gear 2b through gears 33, 35 with the help of a clutch 15. In addition, brakes 16, 17 are attached to barrels 3, 4 respectively. If a required image movement values on the front and reverse side is set in an input part 21, the 13, 17 are in ''OFF'' position, and the 14, 15, 16 in ''ON'' position. Then the rubber barrel 3 on the reverse side and the plate barrel 4 on the reverse side rotate until a rotary angle detector 18 detects a set value and a front image position is adjusted. Next, the 13, 14 are in ''OFF'' position and the 15, 16, 17 in ''ON'' position and the reverse side plate barrel 4 rotates until a rotary angle detector 19 detects a set value, adjusting a reverse side image position. |
