Claims

[Scope of utility model registration request]

A stepping motor drives the transport mechanism to transport the label paper with the label attached to the backing paper.
When the label is positioned at a predetermined printing position, printing is performed by the printing means, and after printing is completed, the label is separated from the mount and projected to a label take-out section, and the presence or absence of this projected label is detected by a sensor. , when the sensor detects the presence of a label, the conveyance of the label paper is stopped; when the sensor detects the absence of a label, the conveyance stop state of the label paper is canceled, and the printing means prints on a new label. In the label printer, the motor holding means is configured to forcibly hold the stepping motor in a stopped state, and the motor holding means is operated while the sensor is detecting the label after the label is projected into the label ejecting section. . A label printer, further comprising a holding operation control means for canceling the operation of the motor holding means when the sensor detects the absence of a label.
