Abstract

A printer comprises a housing which is composed of a box-shaped main body section with an opening on one surface thereof and a cover for opening and closing the opening of the main body section and forming a paper discharge port between the cover and the main body section at the time the cover is located at a position to close the opening; a storage section houses a roll paper; a printing section carries out printing on the paper; a cutter which has a cutting edge used to cut the paper; a support section which supports the cutter in a manner of freely moving between a use position at the time of cutting the paper by the cutting edge and a non-use position close to an edge of the paper discharge port with respect to the use position.

First claim

What is claimed is:

1. A printer, comprising:
a housing comprising
a main body section with an opening on one surface thereof;
a cover for opening and closing the opening of the main body section;
a paper discharge port between the cover and the main body section at the time the cover is in a closed position with respect to the opening;
a storage section configured to house a roll paper; and
a printing section configured to carry out printing on the roll paper;
a flat plate section comprising:
a mounting section that attaches the flat plate section to the main body section;
a cutting edge for cutting the roll paper; and
a pair of support sections attached to the mounting section at opposite ends of the flat plate section and comprising respective levers that project downward from a front surface side of the flat plate section, the pair of support sections are configured to support the flat plate section in a manner of freely moving between a use position at the time of cutting the roll paper by the cutting edge and a non-use position close to an edge of the paper discharge port with respect to the use position, and wherein a downward pressure on the respective levers at a front end of the cover curves the cutting edge downward and causes the support section to create an elastic force that operates as a spring and moves the flat plate section to the use position.

2. The printer according to claim 1 , wherein
the support section positions the flat plate section at the non-use position at the time the cover is in an open position with respect to the opening.

3. The printer according to claim 2 , wherein
the pair of support sections position the flat plate section at the use position at the time the cover is in the closed position with respect to the opening.

4. The printer according to claim 2 , wherein
the support section positions the flat plate section at the non-use position at the time the cover is in the open position with respect to the opening.

5. The printer according to claim 1 , wherein
the housing has a recess in which the flat plate section enters at the edge of the paper discharge port as the non-use position.

6. The printer according to claim 5 , wherein
the cutting edge of the flat plate section is configured to enter the recess in the non-use position.

7. The printer according to claim 1 , wherein
the housing comprises a box-shaped main body section.

8. The printer according to claim 1 , wherein
the paper discharge port comprises a slit-shaped hole in the housing.

9. The printer according to claim 1 , wherein
the cover rotates about an end to switch between the opened and closed positions.

10. The printer according to claim 1 , wherein
the flat plate section comprises metal on the cutting edge.

11. A portable printer, comprising:
a housing comprising
a main body section with an opening on one surface thereof;
a cover for opening and closing the opening of the main body section;
a recess;
a paper discharge port between the cover and the main body section at the time the cover is in a closed position with respect to the opening;

a storage section configured to house a roll paper; and
a printing section configured to carry out printing on the roll paper;
a cutter attached to the main body section at a mounting section, the cutter comprising:
a cutting edge for cutting the roll paper, the cutter configured to enter the recess as a non-use position; and
a support section attached to the mounting section and comprising a spring and a lever that projects downward from a front surface side of the cutter, the support section is configured to support the cutter in a manner of freely moving between a use position at the time of cutting the roll paper by the cutting edge and the non-use position close to an edge of the paper discharge port with respect to the use position, and wherein a downward pressure on the lever at a front end of the cover curves the cutting edge downward and causes the spring to provide an elastic force and moves the cutter toward the use position.

12. The portable printer according to claim 11 , wherein
the paper discharge port comprises a slit-shaped hole in the housing.

13. The portable printer according to claim 11 , wherein
the cover rotates about an end to switch between the opened and closed positions.

14. The portable printer according to claim 11 , wherein
the support section positions the cutter at the non-use position at the time the cover is in an open position with respect to the opening.

15. The portable printer according to claim 11 , wherein
the support section positions the cutter at the use position at the time the cover is in the closed position with respect to the opening.

16. The portable printer according to claim 11 , wherein
the support section positions the cutter at the non-use position at the time the cover is in the open position with respect to the opening.

17. The portable printer according to claim 11 , wherein
the cutter comprises a flat plate section comprising metal on the cutting edge.

18. The portable printer according to claim 11 , wherein
the cutting edge has a saw-shape.

19. A method of preventing injury to a user of a portable printer, comprising:
providing a housing comprising a main body section, a cover that opens and closes the main body section, a recess, a paper discharge port between the cover and the main body section when the cover is in a closed position, a storage section that houses paper, and a printing section that facilitates printing on the paper;
providing a cutter attached to the main body section at a mounting section, the cutter comprising a cutting edge, a support section attached to the mounting section and comprising a lever;
configuring the cutter to enter the recess when in a non-use position;
configuring the support section to support the cutter in a manner that freely moves between a use position and the non-use position, wherein in the use position the cutting edge cuts the paper; and
configuring the lever such that a downward pressure on the lever at a front end of the cover curves the cutting edge downward and moves the cutter toward the use position by an elastic force of the support section that operates as a spring on the cutter.
