Ink film holding device and film reel

An ink film holding device comprising:

• a supply reel around which an ink film is wound;
• a first supporting member that is mounted detachably to one axial end of the supply reel and includes a rotating portion that is fitted to the one axial end of the supply reel and
• means for generating a braking force, which includes the rotating member, with respect to rotation around an axis of the supply reel;
• a second supporting member that is mounted detachably to a second axial end of the supply reel, for supporting the second axial end of the supply reel such that the second axial end is rotatable about the axis of the supply reel;
• a winding reel that is arranged parallel to the supply reel, for winding up the ink film that is guided to the winding reel from the supply reel;
• a third supporting member that is mounted detachably to one axial end of the winding reel and is rotated in a predetermined winding direction;
• a fourth supporting member that is mounted detachably to a second axial end of the winding reel, for supporting the second axial end of the winding reel such that the second axial end is rotatable about an axis of the winding reel;
• a first side plate for supporting the first supporting member and the third supporting member such that the first and third supporting members are rotatable about their respective axes;
• and
• a second side plate to which the second supporting member and the fourth supporting member are fastened;
• wherein the means for generating a braking force is effective to tension the ink film between the supply reel and the winding reel so that wrinkles or slack of the ink film are prevented.
