<p>PURPOSE:To make a delivery roller part rotatable to a separation roller part to the pulling-out and pushing-in action of a cassette, by providing a rotation lever rotating with a first shaft as a center according to the rotation of a cam lever. CONSTITUTION:When the drive means of a paper feeding device is turning on, sheets 22 are fed with a delivery roller 16 and a separation roller 12 rotated with a drive gear 10, however a gear 29 is not rotatable because it is loosely engaged with a first shaft 11. When the sheets 22 are fed up to be supplied, the pulling-out of a cassette 3 causes a cam lever 24 to be slidably moved along a roller 23 provided on the side wall 2a of a cassette casing 2, and when a paper feeding mechanism 6 comes outside the cassette casing 2, the outer periphery of the other side arm 24b is abutted to the outer periphery of a roller 23 to begin the rotation of the cam lever 24, a gear 29 engaging with the tooth form 26 of the cam lever 24 is rotated to turn a rotation lever 28, and an arm 14 engaging via a pin 31 is rotated together, consequently a delivery roller part 8 is rotated to the first shaft 11.</p> |
