Abstract
The present invention provides an improved printer head for using a detachable cassette, particularly the printer head stationary mounted on a print station for using a detachably loadable cassette on the station, the cassette integrally having a webbed label together with a platen roller therein. In prior art, however, a conventional printer head is disadvantageous that a webbed label is often broken during the replacement of the cassette due to the absence of suitable locking mechanism to refuge the printer head from a platen roller so as to facilitate and ensure the safe replacement of webbed label when the cassette is replaced. In order to solve such disadvantages, the present invention provides an improved printer head capable of constantly being held at a position apart from a platen roller to refuge in the upper portion as far as no cassette is loaded on the print station. The locking mechanism is released by manually operating a lever, however, even if the manual lever is operated contrary toward wrong direction due to the user's mis-operation, however, the printer head of the present invention will return to a correct direction automatically in response to the absence of the platen roller under the printer head.
