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 3):
The sheet feeder according to  claim 2 , wherein the adjusting mechanism includes:\n a pinion disposed in the body of the paper cassette and capable of translation on the body in the direction in which the paper cassette slides between the opened and closed positions; a rack fixed inside the housing so that teeth of the rack are aligned along a trajectory on which the pinion moves when the paper cassette slides between the opened and closed positions; and an interlocking mechanism that links sliding of the guide to translation of the pinion, and links rotation of the pinion engaging with the rack to motion of the supporter, thus adjusting a displacement of the first end relative to the second end of the elastic member continuously to the number of rotations of the pinion.
