A transmission mechanism is installed in a machine and driven by a motor to pick up and feed paper. The mechanism includes a transmission gear and a return gear turned by a motor through a reduction gear train, a rocker turned with the transmission gear to move a rocker gear, an idle wheel, a transmission shaft covered with a rubber roll for feeding paper, a paper feeding gear wheel mounted on one end of a transmission shaft and meshed with the return gear, a first paper pick up gear having a peripheral surface section, a second paper pick up gear turned with the first paper pick up gear and having a peripheral surface section, a rubber cam synchronously turned with the first and second paper pick up gears, wherein when the motor is turned in one direction, the rocker is moved rightwards to force the rocker gear into mesh with the first paper pick up gear. When the motor is turned in the reversed direction, the rocker is moved leftwards to disengage the rocker gear from the first paper pick up gear and to force it into engagement with the idle wheel.
