    摘要: PROBLEM TO BE SOLVED: To provide a sheet storage device which has improved easiness of setting sheets by causing a sheet mounting means to always stand by on a fixed position with simple constitution.SOLUTION: When a sheet cassette 10a is pulled out of the body of an image forming apparatus 100, winding pulleys 40a, 40b are rotated by the weight of a lift plate 30 in the direction in which wires 43a, 43b are drawn out. An idle gear 47 engaging with a gear part 40ab of the winding pulley 40a is also rotated. When the idle gear 47 is rotated by a predetermined amount, the engagement part 47b of the idle gear 47 is engaged with a second arm part 50c of a torsional spring 50. Since an energizing force of the torsional spring 50 is set larger than the force that rotates the idle gear 47 by the downward movement of the lift plate 30, the rotation of the idle gear 47 and the winding pulley 40a is regulated and, thus, the upper surface of the lift plate 30 is always stopped on a substantially constant position equal to or higher than the lower end part 49 of sheet supply opening parts 31a, 31b.

    摘要: PROBLEM TO BE SOLVED: To provide a feed device capable of effectively suppressing double feeding of sheet members positioned under the uppermost sheet member when the uppermost sheet member among the sheet members placed in a stacked state is fed, and to provide a recording device.
    SOLUTION: This automatic paper feed device 13 includes a paper guide 17 for placing paper P thereon in a stacked state, a feed roller 23 for delivering the uppermost paper P among the paper P, a gate member 29 having a sloped surface 29a with which the end of the delivered paper P is collided, and a torsion coil spring 31 which biases the gate member 29 to the feed roller 23 side. The uppermost paper P with the front end of which the sloped surface 29a is collided separates the gate member 29 from the feed roller 23 by the amount of the thickness of the paper P against the biasing force of the torsion coil spring 31. The automatic paper feed device 13 further comprises a turning member 33 which is turned in the direction in which the biasing force of the torsion coil spring 31 is increased after the end of the uppermost paper P passes through the sloped surface 29a.
