<p>PURPOSE:To decrease driving force by dividing a system for transmitting the driving force of a loading motor to two driving systems and providing further a clutch mechanism for connecting/disconnecting the transmission routes between both driving systems. CONSTITUTION:The driving system is divided to the 1st driving system to which the driving force is transmitted from the 1st gear 37 and the 2nd driving system to which the driving force is transmitted from the 2nd gear 41. The clutch mechanism for connecting/disconnecting the transmission routes between the 1st gear 37 and the 1st driving system as well as between the 2nd gear 41 and the 2nd driving system is further provided thereto. A clutch lever 40 of the clutch mechanism has a driving pin 40a engaged with the groove 39a of a plate cam 39 so that the lever is oscillated around the axis within a certain turning angle by the operation of the cam 39. The change-over of the operating condition is thus made possible.</p> |
