A motor (9) and driven gear (11) are mounted on an arm (14) of a mounting bracket (12), and a driven gear (4) is mounted on a pin (3), the upper end of which has a recess (6) and a head (7) engaged with the arm to restrain it against movement longitudinally of the pin. The arm is, however, permitted some resilient displacement, perpendicular to the axes of the gears. The gear axes are thus maintained in parallel relationship. <IMAGE> |
