Abstract

A printer includes a body having an opening; a lid that is rotated to open and close the opening, a sheet discharge port being formed between the lid and the body when the lid is in a closed position; a printing mechanism; a first sensor that is disposed closer to a first end of the lid and is capable of detecting whether the first end of the lid is in the closed position; a movable part that is provided on one of the lid and the body and moves when pressed by a jammed sheet; and a second sensor that is provided on another one of the lid and the body at a position closer to a second end of the lid to detect the movable part and is capable of detecting that the second end is not in the closed position and the movable part is moved.

Claims (67)

1 . A printer comprising:

a body including a holder that holds a strip-shaped sheet and having an opening;

a lid one side of which is rotatably supported along an edge of the opening and that is rotated to open and close the opening, a sheet discharge port being formed between the lid and a part of the body when the lid is in a closed position to close the opening, the lid having a first end and a second end opposite the first end in a width direction of the lid;

a printing mechanism that performs printing on the sheet;

a first sensor that is disposed closer to the first end of the lid than to the second end of the lid and is capable of detecting whether the first end of the lid is in the closed position;

a movable part that is provided on one of the lid and the body and moves when pressed by the sheet jammed in a section between the printing mechanism and the sheet discharge port; and

a second sensor that is provided on another one of the lid and the body at a position closer to the second end of the lid than to the first end of the lid and is capable of detecting that the second end of the lid is not in the closed position and the movable part is moved.

2 . The printer according to claim 1 , further comprising:

a processor configured to

determine whether the printing by the printing mechanism is in progress upon receiving a signal from the second sensor,

determine that a paper jam has occurred when the printing is in progress, and

determine that the second end of the lid is not in the closed position when the printing is not in progress.

3 . The printer according to claim 2 , further comprising:

a notification device, wherein

the processor is configured to control the notification device to notify of the paper jam or that the second end of the lid is not in the closed position.

4 . The printer according to claim 1 , further comprising:

a cutting mechanism that is disposed between the printing mechanism and the sheet discharge port and cuts the sheet, wherein

the lid covers the cutting mechanism.

5 . The printer according to claim 4 , further comprising:

a motor that drives the cutting mechanism; and

a processor, wherein

the cutting mechanism includes a fixed blade and a movable blade that faces the fixed blade, and

the processor is configured to control the motor to move the movable blade toward the fixed blade to cut the sheet.

6 . The printer according to claim 5 , wherein

the processor is configured to control the motor to drive the cutting mechanism in one of a full-cut mode in which a portion of the sheet is fully cut off and a partial-cut mode in which the portion of the sheet is partially cut off.

7 . The printer according to claim 6 , wherein

the movable blade has a V-shaped cutting edge, and

in the partial-cut mode, the processor controls the motor to stop the movable blade at a position at which a valley of the V-shaped cutting edge does not reach a cutting edge of the fixed blade.

8 . The printer according to claim 1 , wherein

the lid opens and closes the holder.

9 . The printer according to claim 1 , wherein

the movable part includes a sheet guide that guides the sheet, and

the movable part rotates when the sheet guide is pressed by the jammed sheet.

10 . The printer according to claim 9 , wherein

the movable part further includes a rotation shaft around which the movable part rotates, and

the rotation shaft is located below the sheet guide.

11 . The printer according to claim 9 , wherein

the movable part further includes a rotation shaft around which the movable part rotates, and

the rotation shaft is located above the sheet guide.

12 . The printer according to claim 1 , wherein

the movable part includes a sheet guide that guides the sheet, and

the movable part slides when the sheet guide is pressed by the jammed sheet.

13 . The printer according to claim 12 , wherein

the movable part includes a protrusion, and

the body includes a rail that slidably supports the protrusion.

14 . The printer according to claim 1 , wherein

the lid includes a detection part that is located closer to the first end of the lid than to the second end of the lid and is detectable by the first sensor, and

the movable part includes a detection part that is located closer to the second end of the lid than to the first end of the lid and is detectable by the second sensor.

15 . The printer according to claim 14 , wherein

the second sensor includes a light emitter and a light receiver that face each other across a slit, and

the detection part of the movable part enters and exits the slit.

16 . The printer according to claim 15 , wherein

the second sensor outputs a signal when the detection part of the movable part is in the slit.

17 . The printer according to claim 1 , wherein

the movable part includes a sheet guide that guides the sheet, and

the sheet guide extends in a width direction of the sheet and has a length greater than or equal to a width of the sheet.

18 . The printer according to claim 1 , wherein

the printing mechanism includes a print head and a platen, and

the platen is rotatably attached to the lid.

19 . The printer according to claim 1 , wherein

the sheet discharge port is formed between the lid and the body.

20 . The printer according to claim 1 , further comprising:

a cutting mechanism that is disposed between the printing mechanism and the sheet discharge port and cuts the sheet; and

another lid one side of which is rotatably supported along an edge of another opening of the body and that is rotated to open and close said another opening, wherein

the lid covers the cutting mechanism,

said another lid opens and closes the holder, and

the sheet discharge port is formed between the lid and said another lid.
