The rear end section of a clamp member 26 is pressed down against the force of a spring 28, a press down nail 27 is separated from a bottom surface of the depressed section 22, an ink donor film 1 is inserted into the groove 23, and the front end edge thereof is contacted to the innermost recess of the groove uniformly. The depression against the clamp member 26 is released, a center portion of the ink donor film end section is pressed down to the bottom surface of the depresed section 22 by the press down nail 27. |
