Although not shown, a film supply magazine is provided between the film developing device and the film discharging device 2, and a new sheet film is inserted into the empty cassette 5 from there.

The endless conveyor belt 15 has two conveyor rollers 16.1
The conveyor belt 15 is disposed below the retraction conveyor rollers 9 and 10. This conveyor belt serves as storage means for storing the film 3 between the film discharge device 2 and the developing device. The conveyor belt 15 is
It has a plurality of storage partitions 15a spaced apart from each other at equal intervals.

This storage compartment is located in the area of the roller 6.17 and the belt 1
5 protrudes radially from the belt perpendicular to 5.

The storage partitions 15a are configured as elastic clamping claws, and are each provided with at least one protrusion 15b for clamping each sheet film 3. All the protrusions 15b extend laterally in the same direction. The thickness of each of these protrusions is such that a clamping claw is formed at the straight portion of the conveyor belt 15.
Thereby, each sheet film 3 is held between two adjacent claws.

The roller 8.17 is moved by a motor (not shown) to the retracting conveyor roller 9. The conveyor belt 15 is driven in the direction of the arrow 18 and is driven away from the IO. The conveyance rollers 9 and 10 are located at the extension of the first clamping claw 15a in the conveyance direction, and are positioned behind the straight portion of the conveyance belt 15 (as viewed in the conveyance direction).

A lifting device is provided in front of the straight portion of the conveyor belt 15 to lift up the sheet film stored in front of the intermediate portion 15d between the first and second clamping claws. This lifting device consists of a vertically extending chain 28 driven via gear rollers 1, 9', 20. A claw 21 is located at the vertical part of the chain 28 facing the conveyor belt 15.
is fixed. This claw 21 is provided with a cut groove 21a facing the lower end of the sheet film. The claw 21 is configured to be movable up and down by a chain 28.

The claw 21, which engages with the edge of the sheet film at the lowest end position, moves between the lowest end position and the uppermost end position, as shown by the dashed line. This uppermost position corresponds to the position of the slot 22a provided in the guide 22, by which the first sheet film is lifted upwards from the storage device and into the space between the discharge rollers 12.13. be guided.

The guides 11.22 are funnel-shaped guides and follow the discharge rollers 12,13.

When the sheet film 3 is taken out from the cassette 5 and fed between the retracting conveyor rollers 9 and 10, these rollers are actuated by the interrupter 23, and the sheet film is moved upward along the guide 11 onto the conveyor belt. 1
5 on the straight line section. Grooves 10a are provided at equal intervals around the roller IO on the side. When the rear end of the sheet film 3 leaves the rollers 9 and 10, the rear ends of the sheet film fall into the grooves 10a, and the sheet film is conveyed by the roller 1O-1- and protrudes from the conveyor belt. It is dropped into the gap 15c formed between the clamping claws extending vertically. When the entire sheet film enters the gap 15c, the conveyor belt 15
．． The rollers 16,17 are actuated and the clamping pawls 15a are moved by a distance corresponding to the distance of adjacent clamping pawls. Thereby, the sheet film 3 is clamped by each vertically protruding clamping claw. If there is no next film sheet from the cassette 5, the rollers 9, 10 are turned off. The conveyor belt is moved further intermittently until the sheet film reaches the pawl 21 of the lifting device. On the other hand, film discharge device 2
When another sheet film 3 is removed from the
As described above, when the entire sheet film 3 that falls into the gap between the adjacent clamping claws 15a of the conveyor belt 15 and is sequentially stored on the conveyor belt reaches the film removal part,
The developing device generates a signal, which activates the unloading device 28, 21 in a generally well known manner, and the sheet film 3' is conveyed to the ejecting rollers 12, 13 and fed to the developing device via the ejecting slot IC. Ru. The discharge rollers 12, 13 are provided with detection sensors such as photointerrupters 24, so that after the film has passed through the rollers, the lifting device is returned to its initial position. During such operations, the transport bell)15. The drive mechanism driving the lifting device 21, 28 as well as the developing device must be synchronized.

The storage means constituted by this transport belt makes it possible to quickly empty the film press, transport the film to the storage device and, if necessary, activate the development device. The storage capacity is dependent on the length of the conveyor belt (15) and the length of the straight section between the rollers (16, 17). This length can be adjusted according to the operating speed of the cassette waste device as well as the development speed capabilities, and the buffer can be formed by the transport belt.

The conveyor bell) 15 extends across the maximum width of the film in a direction transverse to the conveyance direction, and can be provided with four parts that engage with the same lifting claw 21 driven in synchronization at a plurality of locations. However, when the sheet film is clamped by the clamping claws over its entire width, it is not favorable for the film, so multiple small conveyor belts are provided, distributed over the entire width of the device, and each conveyor belt is provided with a lifting device. You can do it like this. The position of the smaller conveyor belts as well as the lifting devices and the spacing between them must be such that the film is captured by at least two conveyor belts and two lifting devices arranged parallel to each other and operated synchronously. .

It is also possible to provide separate drive mechanisms for the rollers 9, 10, 12, 13, the conveyor belt, and the lifting device, and a control device for controlling these mechanisms. For example, five sheet films are sequentially stored on a conveyor belt, and when the first sheet film among the five sheets is supplied to the storage device, the lifting device is first activated. Subsequently, the discharge rollers 12 and 13 are operated synchronously. The storage and lifting device has the function of storing a plurality of films at the same time and supplying them to the developing device at a predetermined rhythm.

A feature of such an arrangement is that the films to be stored are separated from each other and are not stored in a stack.

Alternatively, a device for supplying the sheet film may be disposed below the conveyor belt, and the sheet film held by the holding claws may be dropped toward a discharge roller located at the bottom of the housing. Alternatively, the sheet film may be dropped into the gap 15c and guided upward from the gap to the conveying roller. Furthermore, a suitable discharge device may be provided between the gaps 15d of the conveyor belt.

It is also possible to use the variants or embodiments described above alone or in combination.

[Effect] Below 1. As described, according to the present invention, it is possible to store the sheet film discharged from the cassette with a simple configuration and efficiently guide it to the developing device, which is the next processing step.
