THERMAL PRINTER

摘要

The present invention relates to a thermal line printer for a small recording terminals such as a terminal for POS (point of sales), a handy terminal, a measuring apparatus or the like, also relates to a driving device for the thermal line printer. In the structure of a conventional thermal line printer, there is limitation in decreasing the dimension of depth under the circumstance that the downsizing of an apparatus is desired. By installing the thermal line printer in the state of upright, the dimension of the depth can be decreased. However, in this method, the user can not see the state of printing because the recording paper falls down toward the users side for the gravity thereof when the paper is ejected after printing. The present invention solves the above problems by disposing a line type thermal head (5) and a platen roller (2) in such a manner that a tangential line to the platen roller (2) at a pressed point between the line type thermal head (5) and the platen roller (2) intersects the short side of the body of the printer in a plane projecting the body along the axial direction of the platen roller (2), and by ejecting the recording paper from the short side. <IMAGE>
