Abstract
A pick-up device disposed between an input tray and a feeding path includes a paper feeding unit for feeding paper, a separation roller disposed opposite to the paper feeding unit, a blocking arm disposed between the input tray and the paper feeding unit and configured to be switchably disposed between a blocking position for blocking the paper and a feeding position for passing the paper through the feeding path, and a guiding arm disposed in the feeding path through a pivot shaft and having a guiding portion. The pivot shaft is located upstream of the separation roller, and the guiding portion is swingably disposed in a seam space formed by the paper feeding unit and the separation roller.
Claims3
A pick-up device being disposed between an input tray and a feeding path of an automatic feeder and comprising:
- a paper feeding unit for picking up paper from the input tray;
- a separation roller disposed opposite to the paper feeding unit and contacted with the paper feeding unit;
- a blocking arm disposed between the input tray and the paper feeding unit and configured to switch between a blocking position for blocking the paper and a feeding position for passing the paper through the feeding path;
- and
- a guiding arm pivotally arranged in the feeding path via a pivot shaft disposed upstream to the separation roller, the guiding arm having guiding portion, a lifting portion and a blocking portion, the guiding portion being swingably disposed in a seam space formed by the paper feeding unit and the separation roller, the lifting portion being arranged upstream to the guiding portion in a paper feed direction, and the blocking portion being arranged upstream to the lifting portion in the paper feed direction;
- wherein a distance from an axle of the separation roller to the guiding portion is greater than a radius of the separation roller, a vertical distance between the paper to be fed and the guiding portion is greater than a vertical distance between the paper to be fed and the separation roller, an angle between the guiding portion and the feeding path is smaller than an angle between the lifting portion and the feeding path, and the angle between the lifting portion and the feeding path is smaller than an angle between the blocking portion and the feeding path when viewed from an axial direction of the separation roller.
