A translation cam arrangement comprises a translation cam (160) and an eccentric gear (167) rotatably secured to the translation cam (160), and as the eccentric gear (167) is rotated by a driving gear (154) meshed therewith, the translation cam (160) reciprocates in correspondence with various distances between centers of both the gears (154, 167). Thus, there is no need for another cam arrangement for moving the translation cam (160). |
