PROBLEM TO BE SOLVED: To provide a hot-pen suitable for use of erasing after recording by hand writing on a reversible thermal recording material. SOLUTION: This hot pen has a pen 11 at its tip, and a lead wire 12 at its rear end. A heater is provided inside a pen part 10b, and the pen 11 is heated with the heater. A switch 13 is provided to a holder part 10a, and temperature of the heater is varied in recording and in erasing. Furthermore, the temperature of the heater satisfies the purpose either by varying the number of buil-in heaters or by varying output voltage of a power source controller 20. When the pen part 10b is so constituted as to be freely detachable to the holder part 10a, and a plurality of kinds of pens of different thick characters are prepared, recording of a different line thickness can be carried out by changing the pen part 10b. Further, if a thick pen is used in erasing, the erasing can be easily carried out. |
