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 9):
The sheet feeder according to  claim 7 , wherein the supporter includes:\n a line with a first end fixed to the first end of the elastic member; and a drum coaxially fixed to the worm wheel and capable of rotating to reel the line from its second end caused by the rotation of the worm wheel.
