PURPOSE:To make it possible to improve the problem of breakage of lead wires and of replacement of a roll of a printing paper, by providing an oscillatory bracket for opening and closing a paper replacing port through oscillation, a platen roll moved away from or pressed against a thermal head according to the opening or closure of the bracket, and a printing paper roll supporting part supported by the bracket. CONSTITUTION:When an oscillatory bracket 15 is closed to close s paper- replacing port S, a heat generating part 6a of a thermal head 6 energized by the spring force of a coil spring 61 and an outer peripheral part of a platen roll 7 are pressed against each other, whereby a tension suitable for printing is provided. The platen roll 7 is located on the lower side of the head 6, and is supported by the bracket 15. A roll 80 of a thermal recording paper fed by the platen roll 7 is discharged to the exterior of a printer device through 8 discharging port 16. A printing paper roll supporting part 8 is located on the lower side of the head 6, and is supported by the bracket 15. The part 8 is U-shaped in cross section so as to support the roll 80, and is replaceably fitted. |
