Abstract:
In a paper cassette, a guide slides on a tray to place a sheet at a proper position. A lift mechanism uses a restoring force of an elastic member to push up the tray and make the sheet on the tray approach a pickup roller. When the paper cassette is pushed by a user from an opened position, which is out of the housing of a printer, to a closed position, which is in the housing, an adjuster mechanism mechanically converts a force of the user pushing the paper cassette to the restoring force of the elastic member from a time the guide reaches a specific point on a trajectory along which the guide travels together with the paper cassette, thus adjusting the strength of the restoring force continuously to a distance by which the guide overruns the specific point.

Claim (Index 14):
The sheet feeder according to  claim 13 , wherein\n the direction in which the guide slides is parallel to the direction in which the paper cassette travels between the opened and closed positions, the movable reel includes a drum that can rotate to wind the wire around its outer circumferential surface, and the interlocking mechanism includes: a movable member fixed on the guide to move together with the guide; a shaft fixed on the movable member to rotatably support the drum of the movable reel; and a transmission mechanism that converts a torque around the center axis of the drum exerted on the drum into a force moving the supporter, and vice versa.
