Abstract
A printer configured to form an image on roll paper includes a housing configured to house the roll paper and a first guide and a second guide coupled to the housing, the first guide and the second guide each being movable in a width direction of the roll paper, and the first guide being separated from the second guide in the width direction to hold the roll paper therebetween. The printer further includes a detection assembly configured to detect a position of the first guide and a position of the second guide and a controller configured to determine a width of the roll paper based on a detection result of the detection assembly.
Claims12
A printer configured to form an image on roll paper, the printer comprising:
- a housing configured to house the roll paper;
- a first guide and a second guide coupled to the housing, the first guide and the second guide each being movable in a width direction of the roll paper, the first guide being separated from the second guide in the width direction to hold the roll paper therebetween;
- a detection assembly configured to detect a position of the first guide and a position of the second guide, the detection assembly including:
- a first sensor configured to detect whether the first guide is in a first position associated with the first sensor;
- and
- a second sensor configured to detect whether the second guide is in a second position associated with the second sensor;
- and
- a controller configured to acquire a first detection signal from the first sensor and a second detection signal from the second sensor and determine a width of the roll paper based on the first detection signal and the second detection signal.
A printer configured to form an image on roll paper, the printer comprising:
- a housing;
- a first guide movable laterally relative to the housing between a first position and a second position;
- a second guide offset laterally from the first guide and movable laterally relative to the housing between a third position and a fourth position;
- a first sensor configured to provide first sensor data related to a position of the first guide;
- a second sensor configured to provide second sensor data related to a position of the second guide;
- a third sensor configured to provide third sensor data indicating whether the first guide is in the first position;
- and
- a controller configured to determine a distance between the first guide and the second guide based on the first sensor data, the second sensor data, and the third sensor data.
A printer configured to form an image on roll paper, the printer comprising:
- a housing configured to house the roll paper, the housing defining a first groove, a second groove, a third groove, and a fourth groove;
- a first guide defining a first aperture and including a first protrusion;
- a second guide defining a second aperture and including a second protrusion;
- and
- a spindle extending through the first aperture and the second aperture and coupling the first guide and the second guide to the housing,
- the first guide being movable along the spindle between a first position in which the first protrusion is received within the first groove and a second position in which the first protrusion is received within the second groove, and
- the second guide being movable along the spindle between a third position in which the second protrusion is received within the third groove and a fourth position in which the second protrusion is received within the fourth groove.
