Abstract:
A driving device provided in an apparatus for driving a plurality of driving systems by means of motors as driving sources, comprising:a first motor; first and second planetary mechanisms responsive to rotation of said first motor in a desired direction, for revolving in a direction corresponding to the desired direction to transmit a driving force of said first motor; a first driving system disposed for engagement with said first planetary mechanism to have the driving force of said first motor transmitted thereto via said first planetary mechanism when said first motor rotates in a first direction; a second driving system disposed for engagement with said first planetary mechanism to have the driving force of said first motor transmitted thereto via said first planetary mechanism when said first motor rotates in a second direction; a third driving system disposed for engagement with said second planetary mechanism to have the driving force of said first motor transmitted thereto via said second planetary mechanism when said first motor rotates in the first direction; and a switching mechanism responsive to rotation of said first motor in the desired direction, for switching a transmission path for the driving force of said first motor by inhibiting one of said first and second planetary mechanisms from revolving, and for causing the other of said first and second planetary mechanisms to transmit the driving force of said first motor through a transmission path selected by the switching; wherein said first and second planetary mechanisms have first and second restraint members, respectively, for restraining said first and second planetary mechanisms from revolving simultaneously by inhibiting concurrence of engagement of said first planetary mechanism with said second driving system and engagement of said second planetary mechanism with said third driving system.
