Photo Printing Composing Machine

A unit into which is placed a disk font having letters, numerals, characters and punctuation marks imprinted thereon, as on a photographic negative. The disk is turned by a knob to bring the desired character into position for printing. An exposure button is pressed and a positive of the character is reproduced on a photosensitized paper tape which is developed and fixed automatically. The tape may then be pasted onto copy to act as a display and the like.
