Abstract

PURPOSE:To eliminate need for providing a driving coping means for an automatic developing processor by drawing out a control strip while applying the attracting force of an exposure table. CONSTITUTION:A control strip holder taken out from a dark bag is set on the exposure table 31 by opening the light shielding door of a machine and the light shielding door of the machine is closed. The paper fan of the table 31 is actuated and the control strip 1 is attracted to the paper carrying belt 32 of the table 31. In such a case, such constitution that the range other than the range where the strip 1 is exposed from the control strip holder is covered with the mask plate 4 of the control strip holder within the attracting range of the table 31 is obtained. Therefore, the force by which the strip 1 is attracted is larger than the ordinary force by which a print paper is attracted. In such a manner, the carrying force being equal to or above the resistance of the control strip inserting port of the control strip holder is obtained and the belt 32 of the table 31 is actuated. Thus, the strip 1 is carried to a developing machine through an exit part 33.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for controlling liquids using a control strip in an automatic printing and developing apparatus for printing a negative image on a photographic light-sensitive material.

[0002]

2. Description of the Related Art Conventionally, liquid management of an automatic printing and developing apparatus is carried out based on a result obtained by processing a control strip, which is commonly called "const", as a printing paper.

The control strip is a photographic printing paper coated with a photosensitive material, and is loaded in a dark box called a const holder having a light-shielding port dedicated to each automatic printing and developing device in the dark. Then, in a bright room, a dedicated const leader is attached to the tip of the const coming out from the mouth of the const holder with a splice tape and set in an automatic printing and developing device for processing.

FIG. 3 is a perspective view of a conventional const holder. The control strip 20 is inserted into the const holder 21. FIG. 4 is a cross-sectional view of a conventionally used const holder, showing how the loaded control strip is pulled out.

The control strip 20 is the leader 2
2 and the splice tapes 23 and 24. By pulling out the leader 22, the control strip is pulled out from the light shielding opening of the const holder.

[0006]

Although the conventional const holder has a simple structure, its light-shielding port is a velvet butting and the control strip is inserted into the gap. Was hard to insert into.

Further, since the pulling-out force for pulling out the control strip after loading in the const holder is as large as about 1 kg, a leader tape called a const leader is attached and pulled out by the driving force from the automatic printing and developing device.

However, the work of attaching the const leader is not easy, and the work of peeling off the splice tape that adheres the control strip and the leader is also required. It is desired to perform the const processing by a simpler work.

An object of the present invention is to simplify the const processing by using a const holder device having a new structure.

[0010]

In order to solve the above-mentioned problems, in the present invention, the pull-out of the control strip is driven by utilizing the suction force of the exposure table. The const holder has a structure in which the suction force of the exposure table is concentrated on the drive of the control strip, and the control strip can be pulled out by the suction force of the exposure table.

The main operation of the control strip processing apparatus of the present invention is as follows. A box with a light shield constitutes the const holder. Put the control strip in the dark bag from the light shield of the const holder.

However, the tip of the const is about 50 mm,
Leave it outside the const holder. Open the light shield door of the machine, set the const holder taken out from the dark bag on the exposure table, and close the light shield door of the machine. When the paper suction fan of the exposure table is operated, the suction force acts on the control strip left outside the const holder because the const holder blocks most of the suction range of the exposure table.

The tip of the control strip is about 50 mm
Is attracted to the exposure table with a force stronger than the normal paper attraction force. The paper transport belt of the exposure table works, and the control strip is transported to the developing machine through the outlet.

[0014]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the outer appearance of a const holder according to an embodiment of the present invention. The outer surface is composed of a const holder cover 2, a const holder plate 3, and a mask plate 4, and the const holder plate 3 has a lock hole 5
6 is open. Place this in a dark bag (or dark room) with the control strips in a light-tight bag. Place the const holder with side A facing down.

FIG. 2 is a rear view showing the outer appearance of the const holder according to the embodiment of the present invention. Const slot 7
Are shielded by velvet shading members 11 and 12.
The const holder plate 3 has lock pieces 8, pins 9, and lock holes 5 and 6 for setting on the exposure table.

5 and 6 are side sectional views of the const holder in the embodiment of the present invention. Take one control strip 1 out of the light-shielding bag, place the emulsion side on the const holder side, and insert the rear end of the const through the const insertion port 7 until the end of the const reaches the point B in FIG. Put in.

The container insertion port 7 is shielded from light by the light shielding members 16 and 17 and the sponge-shaped light shielding member 18. Shading material 17
Is supported by a fixed plate 13 which is fixed to the light shielding holder plate 14. The control strip 1 in which the film-shaped const guide 15 is inserted is guided.

FIG. 7 is a sectional view of the const holder and the exposure table in the embodiment of the present invention. Open the shading door of the machine with the const holder taken out from the dark bag, set it on the exposure table as shown in the figure, and close the shading door of the machine. The paper fan on the exposure table works, and the control strip 1
Are attracted to the conveyor belt 32 of the exposure table 31. The arrow in the figure indicates the suction range of the exposure table.

The mask plate 4 of the const holder is configured so as to close the suction range of the exposure table except the range where the control strip extends from the const holder. Therefore, the force with which the control strip is attracted is greater than the force with which ordinary print paper is attracted.

In this way, a carrying force equal to or higher than the resistance of the const insertion port of the const holder can be obtained. The paper transport belt 32 of the exposure table 31 works and the control strip 1
Is conveyed to the developing machine through the outlet portion 33.

[0021]

As described above, the control strip processing apparatus of the present invention enables the control strip to be pulled out by applying the suction force of the exposure table with a simple structure. The automatic development processing device does not need a drive corresponding means for pulling out the control strip. Eliminates the hassle of attaching control strips to the leader with a splice tape for driving. As described above, since the const treatment is simplified, there is an effect that the liquid can be quickly managed.
