Abstract
A paper holder is attachable to a recording paper storage chamber of a printer. The paper holder has a loading lid to cover a part of the recording paper storage chamber. And a press mechanism to press an outer of the rolled recording paper to a paper-supply roller is incorporated. The press mechanism consists of a first press plate and a second press plate. In receipt of a slight urge by a torsion coil spring, the first press plate presses the rolled recording paper to the paper-supply roller. On closing the loading lid of the recording paper storage chamber, the hold-down section of the loading lid presses the second press plate, which compresses a compression spring with the first press plate, to apply its counterforce to the first press plate.
Claims17
A recording paper storage device for setting a rolled recording paper to a loading chamber, said rolled recording paper in said loading chamber being pressed to a paper-supply roller, said recording paper storage device comprising;
- a loading lid movable between an open position to open said loading chamber and a closed position to cover said loading chamber;
- press means for pressing said rolled recording paper, said press means being movable in a first direction to press said rolled recording paper to said paper-supply roller and in a second direction that is opposite to said first direction;
- and
- bias means for urging said press means to said first direction, when said loading lid is at said open position, said bias means urging said press means by force smaller than when said loading lid is at said closed position.
A recording paper storage device for setting a rolled recording paper to a loading chamber, said rolled recording paper in said loading chamber being pressed to a paper-supply roller, said recording paper storage device comprising;
- a loading lid movable between an open position to open said loading chamber and a closed position to cover said loading chamber;
- a pair of roll holders for holding both edges of said rolled recording paper;
- a first press member for pressing said roll holder, said first press member being movable in a first direction to press said roll holder to said paper-supply roller and in a second direction opposite to said first direction;
- a first bias member for urging said first press member in said first direction;
- a second press member that is movable in said first direction and said second direction with said first press member engaged, said second press member being pressed in said first direction when said loading lid moves to said closed position;
- and
- a second bias member that urges said second press member in said second direction when said loading lid is at said open position, and urges said first press member in said first direction when said loading lid is at said closed position.
