PURPOSE:To prevent ejection of a tape core by arranging a tape feed guide roller section on a rotary plate which makes freely rotatable a driven core rotating over a ribbon outer diameter with a flat belt. CONSTITUTION:A transfer film 92 is wound on a core 102 in a coil and a belt 87 for feeding films runs along pulleys 86, 88 and 89, a winding core 90 and a transfer film coil 91 supported on a base 83 with a shaft. The pulley 89 is a drive pulley receiving a rotary force from an output shaft of a carriage. With the rottion of the pulley 89, the belt 87 runs and the transfer film 92 runs at the same speed with the belt 87. In this manner, a tape feed guide roller section is arranged on a rotary plate which makes freely rotatable a driven core rotating over the outer diameter of a ribbon with a flat belt thereby providing a cassette for printers which can prevent ejection of the tape core. |
