Abstract
A document feed device includes a tray in which a document is loaded, a pickup roller to be moved upward or downward to a standby position spaced apart from the document or to a pickup position to pick up the document in the tray, a separator to separate each sheet of the picked-up document, an inclined guide to connect an end of an exit of the tray to an entrance of the separator and to guide a bottom surface of the picked-up document, and a document guide member movable to a first position protruding from the inclined guide to guide the picked-up document or to a second position below the inclined guide.
Claims12
A document feed device comprising:
- a tray in which a document including a number of sheets is loaded;
- a pickup roller to be moved by a pickup housing upward or downward to a standby position spaced apart from the document or to a pickup position to pick up the document in the tray, the pickup housing comprising a first magnet;
- a separator to separate each sheet of the picked-up document;
- an inclined guide to connect an end of an exit of the tray to an entrance of the separator and to guide a bottom surface of the picked-up document;
- and
- a document guide member movable to a first position or a second position in association with an upward or downward movement of the pickup roller, the first position protruding from the inclined guide to guide the picked-up document or to a second position below the inclined guide, the document guide member comprising:
- an elastic member to apply an elastic force to the document guide member in a direction toward the first position;
- and
- a second magnet having a polarity such that a repulsive magnetic force exists between the first magnet and the second magnet as the first magnet approaches the second magnet.

A document feed device comprising:
- a fixed tray in which a document including a number of sheets is loaded;
- a pickup housing to support a pickup roller to pick up the document, and to be rotatably movable to move the pickup roller to a standby position spaced apart from the document or to a pickup position in contact with the document in the fixed tray, the pickup housing comprising a first magnet;
- a separator to separate each sheet of the picked-up document;
- an inclined guide to connect an end of an exit of the fixed tray to an entrance of the separator and to guide a bottom surface of the picked-up document;
- and
- a document guide member rotatably movable to a first position or to a second position in connection with the rotatable movement of the pickup housing, wherein the first position protrudes from the inclined guide to guide the picked-up document and the second position is below the inclined guide, the document guide member comprising:
- an elastic member to apply an elastic force to the document guide member in a direction toward the first position;
- and
- a second magnet having a polarity such that a repulsive magnetic force exists between the first magnet and the second magnet as the first magnet approaches the second magnet.
