Abstract
In general, according to one embodiment, a paper sheet storage device that is capable of accurately detecting a near end of a stored roll paper sheet is provided. A paper sheet storage device in an embodiment includes a storage unit configured to store a roll paper sheet obtained by winding a long paper sheet, a near end detection unit configured to detect a near end since a diameter of the roll paper sheet stored in the storage unit becomes smaller, and a pressing unit configured to press the roll paper sheet stored in the storage unit in a direction of the near end detection unit.
Claims18
A paper sheet storage device, comprising:
- a storage component configured to store a roll of paper sheet comprising a wound long paper sheet,
- wherein the storage component comprises a first wall portion and a second wall portion spaced apart from one another and arranged to support the roll of paper sheet therebetween;
- a near end detector configured to detect a near end as a diameter of the roll of paper sheet stored in the storage component decreases,
- wherein the near end detector is fixedly arranged at a non-overlapping position with the roll of paper sheet at a maximum of the diameter extending between the first wall portion and the second wall portion, and
- wherein the near end detector is configured to provide a signal in response to movement of the roll of paper sheet towards the near end detector;
- and
- a pressing component configured to press the roll of paper sheet stored in the storage component in a direction of the near end detector.
A paper sheet processing method, comprising:
- pressing a roll of paper sheet stored in a storage component in a direction of a detecting component, wherein the detecting component is configured to detect a periphery of the roll of paper sheet;
- detecting a near end condition, by the detecting component, based on the periphery of the roll of paper sheet being incident upon a light beam transmitted by the detecting component, wherein a reduction in diameter of the roll of paper sheet causing the roll of paper sheet to move in the direction of the detecting component;
- and
- detecting the periphery of the roll of paper sheet moving from a first position of non-overlap of the detecting component by the roll of paper sheet, towards the detecting component, and into a second position of overlap of the detecting component by the roll of paper sheet, as a function of gravity.
A thermal printer, comprising:
- a thermal print head;
- a storage component configured to store a roll of paper sheet comprising a wound long paper sheet;
- a near end detector configured to detect a near end condition of the roll of paper sheet, as a diameter of the roll of paper sheet stored in the storage component decreases,
- wherein the near end detector is arranged at a non-overlapping position with the roll of paper sheet at a maximum of the diameter extending between the first wall portion and the second wall portion, and
- wherein the near end detector provides a signal in response to movement of the roll of paper sheet into an overlapping position with the near end detector;
- and
- a pressing component configured to press the roll of paper sheet stored in the storage component in a direction of the near end detector.
