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 2):
The sheet feeder according to  claim 1 , wherein:\n the lift mechanism includes\n a supporter supporting a first end of the elastic member and movable to displace the first end of the elastic member relative to a second end thereof, and \n a lift plate shaped as a plate that can swing by the restoring force received from the second end of the elastic member to incline the tray at least partially, and \n the adjuster mechanism uses the force of the user pushing the paper cassette to move the supporter, thus adjusting the position of the supporter according to the overrun distance of the guide, and adjusting a displacement of the first end relative to the second end of the elastic member continuously to the overrun distance.
