DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film processing apparatus in each processing zone of a so-called automatic developing machine for continuously applying processing such as development, fixing, washing with water and drying to a photographed film in each processing zone. .

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a photographed film automatic developing machine (G) has a photographed film (66) pulled out from a patrone pulled by a short leader to develop, fix, wash, and so on. Each processing zone such as drying (53)
(54), (55), (56), (57), (58), (59), and (60), where predetermined processing is continuously performed.
In each processing zone, film (66)
Is a vertically long processing liquid tank (53a) via a transport means (70).
(54a) (55a)... Are transferred from the upper part to the lower part, U-turned from the lower part to the upper part, and transferred to the next processing zone.

In the Japanese Utility Model Publication No. 134187, for example, in order to ensure the conveyance of the short leader, a pair of pulleys (63) (63) arranged vertically is used as the conveyance means (70). The belt (64) is suspended, and the feed hole of the short leader is fitted into a feed protrusion (not shown) protruding from the outer surface of the endless band (64). It is intended to prevent conveyance and meandering. In addition, when moving from one processing zone to the next processing zone, in order to bend the upward short leader and the film downward, it is general that an upwardly curved guide guide straddling an adjacent processing zone is provided. is there.

[0004]

By the way, in a patrone, a film is roll-wound with the emulsion layer serving as a light-sensitive material on the inside and has a rolled pattern, where development, fixing, washing and drying are performed. When returning in each processing zone, or when shifting from one processing zone to the next processing zone, the film is curved in a direction opposite to the winding direction.

[0005] Such curvature is inherently less favorable for films. Also, when the film is conveyed from one processing zone to the next processing zone, it is inherently less preferable for the film to come into contact with the curved guide. In particular, the film may rarely be finely scratched by contact with the curved guide. In a so-called snapshot, even a small scratch that is not so noticeable becomes noticeable when greatly enlarged for research and the like, and may hinder the research and the like. Further, since the upper portion of the processing liquid tank is open, oxidation and evaporation of the processing liquid are performed without limitation.

The present invention has been made in view of the above circumstances, and provides a film processing apparatus in which a film is hardly damaged during processing and oxidation and evaporation of a processing solution can be minimized. The purpose is to provide.

[0007]

In order to achieve the above object, a film processing apparatus according to the present invention comprises a pair of opposed side walls provided above processing liquid tanks in respective processing zones of an automatic film developing machine. In between, a carry-in roller portion composed of a pair of upper and lower rollers, a carry-out roller portion composed of a pair of upper and lower rollers disposed in front of the carry-in roller portion in the horizontal direction, and disposed between the carry-in roller portion and the carry-out roller portion. And an intermediate roller interlocked with them, and a guide guide for guiding the photographed film from the carry-in roller portion to the carry-out roller portion in the horizontal direction, and these rollers are arranged so as to cover the upper part of the treatment liquid in the treatment liquid tank. The roller is configured such that its outer peripheral surface abuts the outer peripheral surface of the adjacent roller in a non-watertight state and both end surfaces abut on the side wall, and a processing liquid storage space is formed, The physical liquid from the treatment liquid bath is made shall become equipped with feeding means for feeding the treatment liquid reservoir space.

According to this film processing apparatus, the photographed film is transported linearly in the horizontal direction in the processing apparatus, and is not bent in the direction opposite to the film winding direction. In addition, the transition from each processing zone to the next processing zone is performed linearly, so that a curved guide guide as in the conventional film processing apparatus is not required, and undesired damage to the film due to contact with the curved guide guide. Is also prevented.

Further, since the processing liquid storage space is formed by a plurality of rollers and a pair of side walls, the amount of the processing liquid evaporated during the film processing is minimized, and the oxidation of the processing liquid is delayed. Will be done.

The lower roller and a part of both rollers of the carry-in roller unit and the carry-out roller unit are immersed in the processing liquid in the processing liquid tank to cover the upper surface of the processing liquid. The evaporation amount of the processing liquid is as small as possible, and the oxidation of the processing liquid is delayed.
