Abstract
A printing device includes a roll paper holder configured to accommodate a first roll paper and a second roll paper and having first and second side walls configured to contact side surfaces of the first roll paper, a remaining amount detecting section having a first projection projecting from the first side wall to detect a remaining amount of the first roll paper accommodated in the roll paper holder, a roll paper guide configured to be installed in the roll paper holder and having a third side wall configured to contact a side surface of the second roll paper when the second roll paper is accommodated in the roll paper holder, and a detection assistance section provided on the roll paper guide and having a second projection projecting from the third side wall in a state of being in contact with the first projection.
Claims7
A printing device comprising:
- a roll paper holder configured to accommodate a first roll paper and a second roll paper having a width smaller than that of the first roll paper and configured to have a first side wall and a second side wall configured to contact side surfaces of the first roll paper;
- a remaining amount detecting section configured to have a first projection projecting from the first side wall to detect a remaining amount of the first roll paper accommodated in the roll paper holder;
- a partition portion configured to be installed in the roll paper holder and configured to have a third side wall configured to contact a side surface of the second roll paper when the second roll paper is accommodated in the roll paper holder;
- and
- a detection assistance section configured to be provided in the partition portion and configured to have a second projection projecting from the third side wall in a state of being in contact with the first projection, wherein
- the first projection includes
- a first projection main body that is movably provided with respect to the first side wall and has a first protrusion, and
- a first urging portion that urges the first protrusion in a direction of projecting to the roll paper holder,
- the second projection includes
- a second projection main body that is movably provided with respect to the third side wall and has a second protrusion, and
- a second urging portion that urges the second protrusion in a direction of moving from the third side wall to the first side wall, and
- the first protrusion abuts on the second projection main body in a state of projecting to the roll paper holder, and urges the second projection main body with the first urging portion in a direction against an urging force of the second urging portion.
A printing device comprising:
- a main body;
- a roll paper holder configured to accommodate a first roll paper and a second roll paper having a width smaller than that of the first roll paper and configured to have a first side wall and a second side wall configured to contact side surfaces of the first roll paper, the roll paper holder is provided in the main body;
- a remaining amount detecting section configured to have a first projection projecting from the first side wall to detect a remaining amount of the first roll paper accommodated in the roll paper holder, the remaining amount detecting section is provided in the main body;
- a partition portion configured to be installed in the roll paper holder and configured to have a third side wall configured to contact a side surface of the second roll paper when the second roll paper is accommodated in the roll paper holder;
- and
- a detection assistance section configured to be provided in the partition portion and configured to have a second projection projecting from the third side wall in a state of being in contact with the first projection, wherein
- the first projection includes
- a first projection main body that is movably provided with respect to the first side wall and has a first protrusion, and
- a first urging portion that urges the first protrusion in a direction of projecting to the roll paper holder,
- the second projection includes a second projection main body that is movably provided with respect to the third side wall and has a second protrusion, and
- the first protrusion urges the second projection main body in a state of projecting to the roll paper holder, and the second protrusion configured to contact side surfaces of the second roll paper.
