Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photographic printing apparatus capable of performing two types of printing within a single printing frame.

[Prior Art] When printing an image on a negative film onto photographic paper, it may be necessary to print two types of images within the same printing frame. For example, when making photo prints for postcards, images of people, buildings, landscapes, etc. are printed as the main image, and characters are printed adjacent to or overlapping this image.
Illustration images such as pictures and computer graphics (CG) are printed.

In this case, since it is necessary to print the main image and the illustration image separately, a mount loaded with a main image negative film containing the main image and an illustration image negative film containing the illustration image is mounted. It is necessary to replace and burn it,
It is unsuitable for photo prints for postcards, etc., which require multiple printed images from the same negative.

SUMMARY OF THE INVENTION In view of the above facts, it is an object of the present invention to provide a photographic printing apparatus which has a simple structure and can easily perform two types of printing within the same frame.
