ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
The present invention relates to a film image reading apparatus, and more particularly, to an image reading apparatus which is adapted to read an image from different kinds of films.
2. Description of Related Art
Various kinds of films have heretofore been used in sizes of 35 mm, 6 cm and 4×5 inches. In the film of size 35 mm, for example, there are two kinds of films, that is, a continuous film and the one mounted one by one. Those films different in sizes are properly used to suit to each objective. Even in the same size of film, there are a wide variety of films to be used. For instance, a color positive film is used for appreciation, a color negative film for printing, and a monochrome film for an artistic purpose. The sizes and characteristics in a variety of films are shown in Table 1 shown below.

SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a film image reading apparatus which is capable of reading an image of films in a plurality of different sizes.
Another object of the present invention is to provide a film image reading apparatus which is capable of setting various reading conditions corresponding to characteristics of each film with a simple structure when an image of films in a plurality of different sizes is read.
A further object of the present invention is to provide a film image reading apparatus which is capable of automatically setting a predetermined condition corresponding to a kind of film wherein various conditions corresponding to each kind of film are preliminarily set.
These and other objects and features of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings which illustrate specific embodiments of the invention.
