Abstract
A printer includes a housing storing a rolled sheet and having an opening, a head, a cover covering the opening, a first flapper attached to the cover via a first shaft at a first end of the flapper, pivoting around the shaft, and biased to press the sheet with a second end thereof, the first end being closer to a front side of the cover than the second end, a second flapper attached to the cover via a second shaft at a first end of the second flapper and pivoting around the second shaft, a second end of the second flapper being closer to the front side than the first end and slidably connected to a center portion of the first flapper, and a sensor detecting that a remaining amount of the sheet has decreased to a predetermined amount, based on an angle by which the second flapper has pivoted.
Claims20
A printer comprising:
- a housing in which a rolled sheet is stored and having an opening through which the rolled sheet can be replaced;
- a head in the housing and configured to print on the rolled sheet;
- a cover by which the opening can be covered;
- a first flapper attached to the cover via a first shaft at a first end of the first flapper, configured to pivot around the first shaft, and biased to press the rolled sheet with a second end of the first flapper, the first end of the first flapper being closer to a front side of the cover than the second end of the first flapper;
- a second flapper attached to the housing via a second shaft at a first end of the second flapper and configured to pivot around the second shaft, a second end of the second flapper being closer to the front side of the cover than the first end of the second flapper and slidably connected to a center portion of the first flapper;
- and
- a sensor configured to detect that a remaining amount of the rolled sheet has decreased to a predetermined amount, based on an angle by which the second flapper has pivoted.
A printer comprising:
- a housing in which a rolled sheet is stored and having an opening through which the rolled sheet can be replaced;
- a printing unit in the housing and configured to print on the rolled sheet;
- a cover by which the opening can be covered;
- a first rotatable member attached to the housing via a first shaft at a first end of the first rotatable member, configured to pivot around the first shaft, and biased to press the rolled sheet with a second end of the first rotatable member, the first end of the first rotatable member being closer to a front side of the cover than the second end of the first rotatable member;
- a second rotatable member attached to the housing via a second shaft at a first end of the second rotatable member and configured to pivot around the second shaft, a second end of the second rotatable member being closer to the front side of the cover than the first end of the second rotatable member and slidably connected to a center portion of the first rotatable member;
- and
- a detection device configured to detect that a remaining amount of the rolled sheet has decreased to a predetermined amount, based on an angle by which the second rotatable member has pivoted.
