Claims

[Scope of Claim for Utility Model Registration] (1) A pick-up roller that feeds the recording paper from the cassette, a feed roller and separation roller that separates and supplies the fed-out recording paper one by one, and is rotatably provided on the shaft 35 of the feed roller. The first gear 33 is driven and rotated by the main motor.
and a paper lifting mechanism that receives power from the first gear to lift up the recording paper in the cassette to a certain height, and a clutch means that attaches and detaches the feed roller shaft 35 to and from the rotating first gear. . A paper feeding device characterized in that said clutch means comprises an electromagnetic clutch 34. (2) Driven by a pick-up roller that feeds the recording paper from the cassette, a feed roller and separation roller that separate and feed the fed-out recording paper one by one, and a main motor rotatably mounted on the shaft 35 of the feed roller. Rotating first gear 33
and a paper lifting mechanism that receives power from the first gear to lift up the recording paper in the cassette to a certain height, and a clutch means that attaches and detaches the feed roller shaft 35 to and from the rotating first gear. , the clutch means includes an electromagnetic clutch 34, a second gear 61 fixed to the paper lifting shaft 45 of the paper lifting mechanism, and transmits the rotation of the first gear 33 to the second gear 61. The feeder is characterized by being provided with a third gear 62 and means 63 and 64 for simultaneously attaching and detaching the third gear 62 to and from the first gear and the second gear depending on the paper raising level. paper equipment.
