Abstract: PURPOSE:To eliminate positioning error of a carrier roller generated from an oblique position, even through the sliding arm is geared in an oblique position from a positioning deformation of a part, by forming one side of the gear in an arc and unifying the center of the arc to the section center of the carrier roller. CONSTITUTION:When a rotary base 5 is rotated in the direction of the arrow B' from a parting condition to a contacting condition, the tip of a sliding arm 13 is guided and slided to the end of a cut 1a and inserted into the cut 1a, since the upper portion of the arm 13 is round, dispite a minor rotation gap at the beginning. In that, the lateral positioning of the sliding arm 13 is completed. Since the center of the arc 13c of the upper end of the sliding arm 13 and the regular position of the section center of a lower carrier roller 10 are unified, the influence of a positioning error of the lower carrier roller 10 generated by an inclination of the sliding arm 13 can be controlled at a minimum. As a result, generation of jamming, inclination of image, and the like, from an oblique positioning can be eliminated perfectly.

The amount of inclusion of oxygen is adjusted in accordance with a vacuum degree. The fused copper is cooled and solidified. After the surface of the ingot is cut, wire drawing is performed at normal temperature. Thus a thin copper wire is obtained. Then the wire is continuously annealed so that the elongation value of the thin copper wire becomes 10% in an inactive gaseous atmosphere. Thus a bonding wire is obtained. At this time, any of the first element group is 5 ppm or less, any of the second element group is 1 ppm or less and the oxygen as the third element is 5 ppm or less. The total amount of the sum of the first element group, the second element group and the oxygen is 10 ppm or less. Such a raw copper material is used.
