Claim Text:
1. A pickup mechanism, comprising: a mechanical frame defining a first locating groove; a first pickup roller disposed under the mechanical frame and partially passed through the first locating groove to project above the mechanical frame; a paper pressing board disposed above the mechanical frame, and the paper pressing board having a bottom board, a top of the bottom board protruding upward to form a movable portion, a front of the movable portion defining a driven link; a transmitting element cooperated with the driven link of the paper pressing board to bring along the paper pressing board to be pressed downward and be raised up; a cover covered on the paper pressing board, and the cover having a top wall, a bottom of the top wall protruding downward to form a locking part; at least one stopper element pivotally mounted to the paper pressing board; and a first elastic element elastically disposed between the cover and the paper pressing board, wherein the transmitting element is capable of rotating freely, the paper pressing board is pressed downward by virtue of an elastic force of the first elastic element to make the first pickup roller generate a normal force for picking up paper, the at least one stopper element breaks away from a restraint of the locking part with the paper pressing board being pressed downward to make the at least one stopper element to move freely, the paper is fed by virtue of the first pickup roller rotating and pushing away the at least one stopper element, and when there is no paper, the paper pressing board is raised up to an original position by virtue of the transmitting element bringing along the driven link of the paper pressing board, at the moment, the at least one stopper element rotates downward to abut against the locking part of the cover to be located at a paper blocking position on account of gravity or other external forces thereof, with the paper pressing board being raised up, the paper blocking function of the at least one stopper element is realized by virtue of the constraint of the locking part.
