Abstract
Official abstract text for this publication.
A label printer includes a print head configured to perform printing on a label sheet, a transporting roller configured to transport the label sheet downstream, a peeling roller configured to transport a backing sheet in a direction different from a travelling direction of a label to peel the label from the backing sheet, and a control unit configured to control rotation of the transporting roller and rotation of the peeling roller, wherein a maximum friction force between the transporting roller and the label sheet are set such that the maximum friction force between the peeling roller and the backing sheet is not greater than a transport force of the peeling roller so as to make a transport error of the label sheet by the transporting roller within an acceptable value.
First claim
Opening claim text (preview).
What is claimed is: 1. A label printer comprising: a print head configured to perform printing on a label sheet including a label attached to a backing sheet; a transporting roller disposed upstream of the print head in a transport path of the label sheet, and configured to rotate in a state where the transporting roller is in contact with the label sheet to transport the label sheet downstream in the transport path; a peeling roller disposed downstream of the print head in the transport path, and configured to rotate in a state where the peeling roller is in contact with the backing sheet, the peeling roller being configured to transport the backing sheet in a direction different from a travelling direction of the label to peel the label from the backing sheet; and a control unit configured to control rotation of the transporting roller and rotation of the peeling roller, wherein the control unit controls a current value supplied to a peeling motor such that a transport force of the peeling roller for transporting the backing sheet is not smaller than a minimum force required for peeling the label and is not greater than a maximum friction force between the peeling roller and the backing sheet, the peeling motor being configured to rotate the peeling roller, and the maximum friction force between the peeling roller and the backing sheet and a maximum friction force between the transporting roller and the label sheet are set such that the maximum friction force between the peeling roller and the backing sheet is not greater than a transport force of the peeling roller so as to make a transport error of the label sheet by the transporting roller within an acceptable value. 2. The label printer according to claim 1 , wherein a static friction coefficient between the peeling roller and the backing sheet is smaller than a static friction coefficient between the transporting roller and the label sheet. 3. The label printer according to claim 1 , wherein a static friction coefficient between the peeling roller and the backing sheet is from 0.1 to 0.3.
