A guide frame is sandwiched between the pair of side frames for guiding the printing medium. A platen roller unit is disposed detachably between the pair of side frames and is pivotably supported relative to the pair of side frames. A thermal head unit is detachably engaged relative to the pair of side frames in opposed relation to the platen roller unit. A head cover plate is disposed between the pair of side frames to cover the thermal head unit and is placeable in either of an open position and a closed position relative to the pair of side frames. A drive unit is detachably mounted on an outer face of one of the side frames for driving the platen roller.
