PROBLEM TO BE SOLVED: To prevent a tension spring for applying a tension on a carrier driving wire for an image processor from being stretched out due to the vibration at a transport time and to prevent the wire from being off a pulley by controlling the tension spring so that the wire may be positioned in a stretched state. SOLUTION: A spring stopper 22 is attached to the inside wall of the housing 1 of the image processor so that the stopper 22 may freely slide in the longitudinal direction of the tension spring 21. A pin part 22a formed at the leading end part of the spring stopper 22 is idly inserted in the elliptical hook part 21b on the wire 12 side of the tension spring 21. Even in the case the tension spring 21 is stretched out and compressed, the hook part 21b is engaged with the pin part 22a, so that the spring 21 does not expand and contract. Thus, the wire 12 is not slackened, then, the wire 12 is prevented from being off the guide pulley. |
