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 16):
The sheet feeder according to  claim 11  further comprising\n a fixed reel fixed to the housing and capable of reeling the wire from its first end, wherein: \n the fixed reel lets out a predetermined length of the wire from its first end, and the movable reel lets out a length of the wire corresponding to the position of the movable reel in the body of the paper cassette, when the paper cassette is in the closed position in the housing; \n the fixed reel draws in the predetermined length of the wire from its first end when the paper cassette is in the opened position out of the housing; and \n the specific point is designed within a volume where the guide can reach at the same time the fixed reel lets out the entirety of the predetermined length of the wire from its first end when the paper cassette is pushed into the housing.
