摘要：PURPOSE:To achieve improvement of operational property and maintenance property by enabling an ink sheet to be easily exchanged, by a method wherein a rolled ink sheet is held in a rotary free manner, and a means by which rotation force is transmitted to a spool to which the top of the ink sheet is fixed is stored in a case. CONSTITUTION:A back tension mechanism 61 (an ink sheet support means) is established to one end side of a spool 52a on which an ink sheet 51 is wound. When the ink sheet 52 is wound on the spool 53, suitable tension is always given, ruck is prevented from occurrence, and an unwinding gear 62 is established to another end side of the spool 52a. Besides, a support member 63 is established to one end side of the spool 53 and a winding gear 64 is established to another end side thereof. Therefore, the ink sheet 52 and the spool 53 are held, in a rotary free manner, to a specific position of a cassette case 51. Herein, the cassette case 51 is partitioned into a plurality of components at specific positions, and has a structure which can be assembled if an ink sheet cassette 16 is intended to be reused.
