Abstract
A printer for printing an image on a sheet stored in a rolled shape, includes a sheet holder by which the sheet in the rolled shape is rotatably held and including at least one side plate movable in a width direction of the sheet and contacting a side surface of the sheet, a printing head by which an image is printed on the sheet that has been conveyed from the sheet holder, a buffer unit between the sheet holder and the printing head and including a plate-shaped member that is connected to an elastic member that generates an elastic force by which the conveyed sheet is pressed, and an adjusting unit by which the movable side plate and the buffer unit is connected such that the elastic force varies depending on a location of the side plate.
Claims16
A printer for printing an image on a sheet stored in a rolled shape, comprising:
- a sheet holder by which the sheet in the rolled shape is rotatably held and including at least one side plate movable in a width direction of the sheet and contacting a side surface of the sheet;
- a printing head by which an image is printed on the sheet that has been conveyed from the sheet holder;
- a buffer unit between the sheet holder and the printing head and including a plate-shaped member that is connected to an elastic member that generates an elastic force by which the conveyed sheet is pressed;
- and
- an adjusting unit by which the movable side plate and the buffer unit are connected such that the elastic force varies depending on a location of the side plate, wherein
- the adjusting unit includes:
- a rotation plate, one end of which is connected to the elastic member, and which rotates when the location of the side plate is changed,
- a shaft, one end of which is connected to the other end of the rotation plate,
- a first gear connected to the side plate and movable therewith along the width direction,
- a second gear that engages with the first gear to rotate therewith, and
- an eccentric cam that engages with the second gear and is connected to the other end of the shaft.

- a printing head by which an image is printed on the sheet that has been conveyed from the sheet holder;
- an elastic member between the sheet holder and the printing head;
- a pressing shaft that is pressed against the conveyed sheet by the elastic member;
- a rotation plate, one end of which is connected to the elastic member, and which rotates when a location of the side plate is changed;
- another shaft, one end of which is connected to the other end of the rotation plate;
- a first gear connected to the side plate and movable therewith along the width direction;
- a second gear that engages with the first gear to rotate therewith;
- and
- an eccentric cam that engages with the second gear and is connected to the other end of said another shaft, wherein
- an elastic force that is applied by the elastic member to the pressing shaft varies depending on the location of the side plate.
