The mounting structure of a roll paper storage case in a conventional thermal printer is shown in FIGS. 4 and 5. In the figure, a mounting frame 1 having an opening on at least one side has a bent flange portion 2 on the edge of the opening. A storage case 4 for storing the roll paper 3 has a semi-cylindrical shape and has a mounting flange 5 facing the bent flange 2, and is fixed by tightening the flange parts 2 and 5 together with screws 6. The storage case 4 has a roll shaft 7 that passes through the core of the roll paper 3.
A support shaft guide groove 8 is formed on the side end surface in order to support the shaft end of the shaft. The edge of the semi-cylindrical cover of the storage case 4 forms a paper feed guide section 9, which extends to the lower part of the platen roller 10 attached to the mounting frame 1. Also, platen roller 1
