Abstract
A paper feeding mechanism includes a feeding path, a driving motor, a bidirectional transmission mechanism, at least one feeding roller, a unidirectional transmission mechanism and at least one blocking roller. The driving motor is controllable to output a driving force towards a forward direction or a driving force towards a reverse direction. The bidirectional transmission mechanism is connected to the driving motor. The at least one feeding roller is mounted in the feeding path. The at least one feeding roller is connected to the bidirectional transmission mechanism. The unidirectional transmission mechanism is connected to the driving motor. The at least one blocking roller is mounted in the feeding path. The at least one blocking roller is disposed to a downstream of the at least one feeding roller. The at least one blocking roller is connected to the unidirectional transmission mechanism.
