Abstract

PURPOSE:To print out a negativ efficiently, by switching optical paths by two mirrors and rotating a holding means, which holds a negative film so that it is orthogonal to the printing face, at 90 deg. around the optical axis of printing in accordance with the size of film pictures. CONSTITUTION:Pictures on a long-sized negative film 11 are printed to a roll photographic paper, which is placed in the upper part of figure and is orthogonal to pictures and is not shown in figure, by a light source lamp 6 and the first and the second mirrors 19 and 20. The running direction of the roll photographic paper and that of the negative film coincide with each other when the film is in the full size; but when it is discriminated by a picture size detecting block 18 that the film is in the half size, a negative film holding means 14 is turned at 90 deg. around a rotation shaft 14b, and said running directions are orthogonal to each other. Thus, pictures of full and half sizes are automatically printed continuously as positives having approximately equal picture size and shape.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows a JI8135 type negative film having a full size screen (24x36mm) and a JISI 35 type negative film having a half size screen (24x18mm) to be joined in series without distinction. Automatic photo printing that automatically prints full-size and half-size images continuously on the same roll of photographic paper as positives with approximately the same screen size and shape from a long negative film (long negative film) Concerning improvements to equipment.

For JISI 35 type film, the screen size is full size (24X: 36 l111
1]) or its 1-2 Hern size (24X18
mm).

Lee Gafilm's development processing methods include a hanger type in which unprocessed 3'H films are hung one by one without being joined and imaged (U+), and a hanger type in which multiple unprocessed films are joined in advance (L7).
There is a Zonema type in which the film is made longer and the film is continuously developed.

The former is 11 times bigger than the developing machine compared to the latter! ! Furthermore, the quality and processing capacity of the film is inferior to the latter in terms of quality and processing capacity, such as the occurrence of uneven development on the two parts and the bottom of the hanging film. Cinema type! The reality is that there is a large shift toward image machines.

When printing a positive image on a roll of photographic paper from a negative film after development, a method has long been used in which individual negative films are joined together in a series and then printed in a long length, using a hanger-type developing machine. In the processed version, it is possible to distinguish between a one-fleuroid screen negative film and a half-size screen negative film by looking at the image (h, +) of the negative film, and to make a long negative film that is spliced separately. On the other hand, those processed with the CII Matype developing machine,
1Ii photographed as unprocessed film before development
Since it is extremely difficult to identify the screen size of the II image, as a result, in a long negative film after processing.

It is practically impossible to avoid the mixing of negative films that are -y4 with each other.

Therefore, a full-size screen on a negative film is a rectangle with long sides along the length of the film, while a half-size screen is a rectangle with short sides along the film's length, and so on. Since both are arranged with exactly 900 degrees of difference in longitudinal direction, they can be printed using the same photoprinting device as positives with approximately the same screen size and shape on roll photographic paper of the same predetermined width. In order to effectively utilize the paper space and print efficiently, it is impossible unless the shape of the full-size screen and the shape of the half-size screen are aligned in the same direction. In order to unify the process, the developed negative films that have already been spliced must be peeled off one by one, and then re-edited by splicing them into full-size negative films or half-size negative films. 1
One thing involved inefficient work.

The present invention was made in view of the problems of the conventional J★ method as described above, and is a long negative film in which a negative film having a full-size screen and a negative film that irritates a half-size screen are joined in series. In the 11th state where these are joined without separating them, both full-size and half-size images (screens) are printed on the same roll of photographic paper.
This is an automatic photo printing device that dynamically prints images continuously as positive images with approximately the same screen size and shape, and is smaller than conventional devices, has a simple structure, and is easy to operate.
