Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a film light room insertion device for inserting exposed film into a film developing machine in a light room.

(Prior art and its problems) Conventionally, in the plate-making process, etc., the film exposed by a color scanner is temporarily stored in a film trunk, etc., and the film trunk is transported to a darkroom where an automatic film developing machine is installed. I opened the film trunk, took out the film, and inserted it into the automatic film developing machine.

However, when using such a procedure, the removal of the film from the film trunk and the insertion of the removed film into the automatic film processing machine must all be done in a darkroom, which not only reduces work efficiency but also causes blockages. It is easy to make a mistake by touching the film surface with one's hand and staining the film, and the automatic film developing machine must be installed in a dark room, which increases equipment costs.

(Purpose of the invention) This invention was made in order to solve the above problem, and it is a film developing machine that can efficiently insert exposed film into the film developing machine in a bright room without touching it. An object of the present invention is to provide a film insertion device into a bright room.

(Means for Achieving the Object) In order to achieve the above object, the device for inserting a film into a film developing machine into a bright room according to the present invention has the following features:
It consists of a light-shielding container for storing the film and a container holder installed at the film inlet of the film developing machine.
A recessed portion recessed inward of the container is formed on the lower surface side of the light-shielding container, and a shutter is provided within the recessed portion to open the film discharge port and to close the discharge port so as to be openable and closable. A descending film guide path is formed in the light-shielding container to guide the stored film down to the film discharge port, and a receiving seat into which the lower end of the light-shielding container is fitted is recessed on the upper surface side of the container holder. An opening operation part that engages with the shutter side in the recessed part and opens the shutter when it is fitted is protruded in the receiving seat, and in the fitted state communicates with the opened film discharge port, and is connected to the film introduction port. A descending film guide path for guiding the film to fall is formed in the container receiver.

(Function) According to this invention, when the lower end of the light-shielding container containing the film is fitted into the receiving seat of the container holder, the opening operation part protruding into the receiving seat is moved into the recessed part during the fitting process. The shutter enters relatively into the shaft and engages with the shutter side, and the shutter is operated to open.

When the film discharge port is opened, the film naturally falls from the film guide path inside the light-shielding container, and is discharged from the film discharge port to the outside of the light-shielding container.
Thereafter, the film naturally falls down the film guide path of the container holder and is guided to the film inlet of the film developing machine.

In addition, during this fitting operation, the lower end of the light-shielding container is fitted into the receiving seat provided in the container holder, and a recessed part is provided on the lower surface side to be fitted, and a film discharge port is opened in the recessed part. Therefore, it is possible to effectively prevent light from entering the film ejection port side when the shutter is opened.

Furthermore, the film outlet and the shutter are provided in the recess, and do not protrude outward in any way, and the shutter is opened by engaging with the shutter side within the recess. This can effectively prevent other members from coming into contact with the shutter side at times.

The end portion 20a is the container receiver 2 (shown in FIGS. 6 and 8).
It is configured to be pushed by a pushing claw 29 on the side. In addition, in this light-shielding container 1, positioning notches 18 are formed at two locations on the lower edge, and in the container receiver 2, a bottom plate 27 of the receiving seat 26 is provided with a groove that faces the notch 18 on the light-shielding container 1 side. Two retaining claws 28 are provided protrudingly. The other configurations are substantially the same as those in the previous embodiment, and the same parts are given the same reference numerals and the explanation thereof will be omitted.

In this apparatus, the light-shielding container 1 is not configured to be detachably attached to the film outlet of the exposure device, so the exposed film 3 is not removed from the exposure device.
The work of collecting the liquid into the light-shielding container 1 will be performed in a dark room. The exposed film 3 taken out from the exposure apparatus is collected into the light-shielding container 1 through the film collection port 6 opened by opening the light-shielding lid 7, as shown by the phantom lines in FIG. The recovered exposed film 3 is placed in the film guide path 1 in the light-shielding container 1.

After that, the light-shielding container 1 with the light-shielding lid 7 closed and kept in a light-tight state is carried to the automatic film developing machine 24 installed in a bright room, and the lower end of the light-shielding container 1 is marked with the imaginary line in FIG. Container holder 2 as shown
8, and then insert it into the receiving seat 26 as it is and seat it as shown in FIG. In this seated state, the locking claw 2 on the container receiver 2 side
8 is engaged with the notch 18 on the light-shielding container 1 side for positioning, and the pushing pawl 29 on the container receiver 2 side pushes the rear end 20a of the shutter 20 on the light-shielding container 1 side. The operation of opening the shutter 20 is almost the same as in the previous embodiment. The exposed film 3 naturally falls from the opened film discharge port 12, passes through the film guide path 31 on the container holder 2 side, and enters the film introduction port 2 of the automatic film processor 24.
5 is inserted.

In each of the above embodiments, the shutter 20 that closes the film outlet 12 of the light-shielding container 1 is of a rotating lever type, but the shutter 20 is not limited to this.
Other operating methods such as a sliding type in which the film outlet 12 is opened and closed by sliding the film outlet 12 may also be used. In addition, the pushing claw 29 on the side of the container receiver 2 is connected to the shutter 20.
The shutter 20 is not limited to a structure in which the film discharge port 12 is opened by acting directly on the shutter 20, but is also possible via a lever mechanism, rack and pinion, sliding pair, or other transmission mechanism.
The film discharge port 12 may be opened by acting on the film discharge port 12.

(Effects of the invention) As described above, according to the film bright room insertion device of this invention, exposed film can be inserted into the film developing machine in a bright room, the work efficiency is improved, and the film developing machine Since there is no need to prepare a darkroom as an installation condition, equipment costs can be reduced. Further, since the film is inserted into the film developing machine only by gravity, the structure of the apparatus itself can be simplified, the film does not come into contact with hands, and the film can be prevented from being soiled by the insertion process.

In addition, the lower end of the light-shielding container, which has a recessed part, is fitted into the recessed receiving seat of the container holder, and when the shutter is opened during the fitting operation, the film is positioned in the recessed part. Light can be effectively prevented from entering the discharge port.

Furthermore, a film discharge port and a shutter are provided within the recess, and the shutter is opened by engaging with the shutter side within the recess, so that other members must be connected to the shutter side when transporting the light-shielding container. This effectively prevents contact with the shutter, and prevents the shutter from being opened inadvertently.
