PURPOSE:To prevent the generation of wrinkle in an ink carrier, by providing a friction means to one end of an ink carrier supply roll to make tensile force added to the ink carrier constant along the width direction thereof. CONSTITUTION:In the supply side of an ink film, a rotation stop 130 is provided to a shaft 123 and the rotation of an ink film supply roll 34a is controlled. For example, when springs 128L, 128R are shortened, the elastic force of each spring becomes large and friction plates 127L, 127L2, 127R1, 127R2 are strongly pressed to pressure control segments 126L, 126R and core presses 129L, 129R to increase friction force. By this friction force, the rotation of the roll 34a is controlled. Therefore, by adjusting the springs 128L, 128R, the generation of wrinkle of the ink film 33 can be prevented. |
