Screw shafts threadably coupled to these connecting members drives the attracter holding members to approach or separate from each other on a line connecting the two guide shafts. Pinions provided near the opposite ends of the guide shafts rotatably move on racks, whereby the attracter holding members are synchronously moved in parallel to each other.
