Patent Number: 6,254,083

Title: Leaf transfer mechanism unit

Abstract: When a driven piece is caused to move forward, a follower piece is allowed to follow the forward movement of the driven piece with the assistance of the biasing force of a biasing member. The follower piece induces the movement of a urging member toward a pickup roller. When the urging member collides against the pickup roller with leaves interposed therebetween, the forward movement of the follower piece is prevented, while the driven piece is still allowed to keep moving forward. The elastic force is stored in the biasing member in response to the forward movement of the driven piece. The urging member is allowed to urge the leaves against the pickup roller by an urging force based on the elastic force stored in the biasing member. When the driven piece is caused to move backward, the follower piece receives the driven piece at the reception surface. The follower piece is allowed to rigidly receive the driving force from the driven piece without any influence of the biasing member. The position of the follower piece is solely determined by the position of the driven piece.
