ABSTRACT:
The present invention provides a printer in which a printing head confronting a platen and a paper pressing roller for pressing a recording paper are attached to the same levers mounted rotatably and turnably and the distance between the top end of the printing head and the platen can directly be changed according to the thickness of the recording paper to be inserted, whereby influences of changes of the paper thickness on the printing state can be eliminated substantially. In this printer, the distance between the top end of the printing head and the platen can be adjusted very precisely by a simple structure.
