  • Patent number: 6307581
    Abstract: The ink film unit is configured by fixing the fixed shaft that penetrates the inside of the hollow, cylindrical feeding reel, right side plate and left side plate and attaching the winding reel to the right side plate and left side plate in a pivotable manner. The main unit is provided with the grooves that house and position the right side plate and left side plate, and the U-figured holders that hold the feeding reel and winding reel. This makes it possible to reduce the space for installation of the ink film unit, reducing the size of the facsimile apparatus.

  • Patent number: 5173718
    Abstract: A scanning head comprises a support member for supporting the head in pressing contact with a platen. The support member has lower strength portions spaced longitudinally of the head, and higher strength portions alternate with the lower strength portions. The support member is easily bendable at the lower strength portions, and the higher strength portions are urged by springs toward the platen. Thus, the head can come into intimate pressing contact with the platen even if the surface flatness of the support member as a whole is not strictly realized.
