Self-regulating media holder

A holder for rolled media, the holder comprising:

• a mandrel defining a drive surface, said drive surface having a spring finger formed at a load edge thereof with said spring finger having a retaining surface extending outwardly from the drive surface when the spring finger positions the drive surface in a first position;
• said spring finger being elastically deformable to move the retaining surface from said first position to a second position wherein the retaining surface is positioned so that it does not extend outwardly from the drive surface and with said spring finger further being biased to move the retaining surface toward the first position;
• and
• a stop at a stop end of the drive surface to block rolled media on the drive surface from lateral movement along the mandrel toward the stop end;
• wherein the retaining surface is defined so that when said rolled media is loaded on the mandrel to a position proximate to the stop, said retaining surface engages said rolled media with said spring finger at a position between the first position and the second position, so that a portion of the force biasing said retaining surface from the second position to the first position is applied to drive the rolled media toward the stop.

A holder for a rolled medium comprising:

• a rolled medium drive surface for receiving the rolled medium;
• a stop means at a first end of the rolled medium drive surface;
• a retaining means at a second end of the drive surface, said retaining means separated from the stop means by a distance defined by a width of the rolled medium, said retaining means being movable between a first position where the retaining means projects above the drive surface and a second position where the retaining means does not project above the contact surface;
• and
• a biasing means for biasing the retaining means from the second position to the first position,
• wherein the retaining means has a translation means for converting the biasing from the biasing means into a force applied to urge the rolled medium toward the stop means.
