Abstract
The present invention provides a thermal printing head which comprises an elongate heat sink plate, an elongate head circuit board mounted on the heat sink plate, a connector board partially overlapping the circuit board, and an elongate presser cover mounted on the heat sink plate to press the connector board into contact with the circuit board. The circuit board has a reduced number of connection terminals arranged locally at a central portion of the circuit board. The connector toward is correspondingly reduced in length. Thus, for pressing the connector board into uniform contact with the circuit board, it is only necessary to provide only a pair of pressure applying screws adjacent the central portion of the circuit board.
