<p>PURPOSE:To eliminate a big shaft of a driving member within a stage part of a member to be driven by making the member to be driven follow the driving member with an arc-shaped locus same as that of the driving member. CONSTITUTION:When an intermittent gear 31 engaged with a driving gear 30 is rotated, a power plate 38 is pressed by a cam 37 and shifted down. Then a driving member 3 interlocking the plate 38 moves upward contrarily centering on a support shaft 1 with an arc-shaped locus. Accordingly a member 4 to be driven is pulled by the member 3 since the member 3 engages a stage part 4a. In this case, the member 4 is supported by a guide member 5 and shifted with an arc- shaped locus since a rubbing part 4c with the member 5 has an arc-shaped form. As a result, the part 4a also draws an arc-shpaed locus in accordance with the locus of the member 3. Thus the member 3 never moves within the part 4a.</p> |
