ABSTRACT:
A label printer including a printing section for printing a given image on a label, a label issue opening for issuing the label after the given image is printed thereon by the printing section, a sensor having a light emitting element and a light receiving element, a first prism having a reflecting surface located on one side of the label issue opening, and a second prism having a reflecting surface located on the other side of the label issue opening. The light emitted from the light emitting element is reflected on the reflecting surface of the first prism, and is then reflected on the reflecting surface of the second prism to reach the light receiving element. When the label is issued from the label issue opening, an optical axis between the reflecting surfaces of the first and second prisms intersects a surface of the label. Thus, the presence of the label projecting from the label issue opening can be surely detected.
