Claims (1)

[Scope of utility model registration request] A head bracket that holds a recording head is disposed between bearing holders that face each other at a predetermined interval, and a head fulcrum shaft that moves largely in the axial direction with respect to the bearing holder and a head that does not move significantly are arranged on this head bracket. The head bracket is removably attached to the bearing holding part by arranging the fulcrum shaft on the same axis, and a nut is screwed onto the head fulcrum shaft, which has a small amount of movement in the axial direction, in the axial direction. a head hanger that stops the movement of the head bracket, rotatably holds the head bracket, and removably holds the head bracket while the head bracket is rotated in a direction in which the recording head approaches the platen roller; A recording head mounting device characterized in that:
