• a head holder configured to support the thermal head rotatably about the axis line of the shaft and detachably in the second direction;
• an insertion part provided on the head holding member, the shaft member being insertable into the insertion part rotatably about the axis line and detachably in the second direction;
• a shaft holder configured to hold the shaft;
• a second engaging part provided on the shaft holder and configured to engage with the first engaging part so that the shaft is rotatable about the axis line and that the shaft does not come off from the shaft holder;
• a guide configured to guide the shaft holder movably between an engaging position at which the first engaging part and the second engaging part engage with each other and a non-engaging position at which the first engaging part and the second engaging part do not engage with each other;
• a fixing member configured to fix the shaft holder to the head holder in a case that the shaft holder is located at the engaging position;
• and
