PURPOSE: To certainly ensure the keeping of a secret by processing the recording pattern formed to a recording medium by the thermal transfer recording of this time to prevent the same from appearing in the thermal transfer recording of the next time.
CONSTITUTION: In the case using a thermal transfer recording medium usable two or more times, for example, an ink ribbon 45 is drawn out from the through-hole 31a of a cassette main body 31 to the outside through one of a pair of the guide rollers 3, 3 provided inside the through-hole 31a and passed between a pair of rolls 5A, 5B through a guide roller 6A and again passed between a pair of the rolls 5A, 5B through a guide roller 6B to be guided into the cassette main body 31 from the through-hole 31a through a guide roller 6C and taken up by a take-up reel 32A through the other guide roller 3. By this method, the ink layer 45 of the ink ribbon 45 mutually comes into contact with a pair of the rolls 5A, 5B under pressure at two places and sharp unevenness 45e due to printing is changed to extremely fine unevenness 45f.
