Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an inspection paper (control strip) which is passed through a developing solution in order to inspect the degree of fatigue of the developing solution in a developing section of a developing apparatus. ) Related to the structure of the control strip magazine.

[Conventional technology]

FIG. 5 schematically shows an example of the configuration of a developing processing apparatus of this type. In the drawing, the photographic printing paper P fed from the magazine section to the exposing section is further guided by guide rollers and the like, A series of developing steps are performed by driving the drying section. When inspecting the fatigue level of a processing solution such as a developing solution in the above-mentioned developing processing section, when processing is carried out using a processing solution having performance characteristics recommended by the photosensitive material manufacturer,
Test strips (control strips) are pre-formed with a latent image so as to form the most appropriate image. Conventionally, a control strip magazine as shown in FIG. 6 has been used for such inspection, and in general, each processing liquid including the developing liquid is inspected periodically according to the processing amount and the number of days of use. Is. In FIG. 6, reference numeral 21 is a magazine main body for accommodating the inspection paper 22, and 23 is attached to the magazine main body 21.
The guide member 24 for guiding the inspection paper 22 to be stored in 1 is connected to one end of the inspection paper 22 by an adhesive tape or the like, and at least one end thereof is guided so that the inspection paper 22 can be pulled out from the magazine body 21. The reader 25 is designed to be set in a state of protruding from the member 23, and 25 is a lid of the magazine body 21. The control strip magazine having the above-described configuration guides the guide portion 23 to the receiving guide 26 provided in the developing processing apparatus through the canopy of the processing apparatus when inspecting the processing solution.
In this case, the light shielding lid 27 (FIG. 5) provided on the upper part of the processing device is removed and set from above the development processing device (see FIG. 7).
Next, instead of the photographic printing paper P, the reader 24 is first adapted to the traveling path, and then the feed roller or the like is operated, so that the inspection paper 22 accommodated in the magazine main body 21 follows the leader 24 and runs. Be led to the road. As a result, the inspection paper 22 is allowed to pass through the development processing solution of the development processing section, and the fatigue level of the development solution is determined by the suitability of the color, density, etc. of the inspection paper that has passed.

[Problems to be solved by the device]

In such a conventional control strip magazine, it is needless to say that the test sheet 22 housed in the magazine body 21 must be protected from light.
The magazine main body 21 set on the development processing device and provided with the guide member 23 is separated from the traveling path of the photographic paper P by a certain distance when set (designated 7th).
(See the drawing), it is necessary to make the light-shielding effect of the receiving guide 26 itself perfect in order to secure the light-shielding property of the inspection paper 22 in the separated portion. Further, in this portion, a guide means such as a guide roller must be provided in order to smoothly connect the inspection paper 22 pulled out from the magazine main body 21 to the traveling path, and therefore, especially the receiving guide 26 as a center of the apparatus. The structure was complicated and had to be larger than necessary. Further, since the magazine body 21 and the traveling path of the photographic printing paper P are separated from each other as described above, it is necessary to increase the dimension of the reader 24 corresponding to the separated portion. Due to the relative relationship, there has been an inconvenience that the storage amount of the inspection paper 22 to be stored in the magazine body 21 has to be reduced.

In view of such circumstances, the present invention provides a control strip magazine which can surely and sufficiently secure the light shielding property to the inspection paper and can realize miniaturization of itself and the development processing apparatus. The purpose is to

[Means and Actions for Solving the Problems]

The control strip magazine according to the present invention is
A magazine main body which is made of a tubular shell that can be divided into two vertically and which allows the inspection paper to be inserted spirally through a slit formed in a mating portion along one longitudinal direction, and the above-mentioned magazine body, A light shield fixed along the edge of the slit,
A pair of end caps, which are attached to both ends of the magazine body and have a spindle positioned on the axis of the magazine body, and one end portion of which is fixed to the edge portion of the slit so as to be inside the magazine body. With a guide sheet arranged in a spiral shape, and a frame body having a slit for mounting on a set plate in the development processing apparatus and rotatably supporting the magazine body via a support shaft of the end cap. It is configured.

When inserting the inspection paper into the magazine body, the inspection paper is inserted along the spirally arranged guide sheet, so it can be stored smoothly in the magazine body without being caught or bent at the other mating part. However, at this time, the light shield completely blocks the light. Since the frame supporting the magazine main body can be mounted from the side of the developing processing device at a position immediately near the traveling path of the photographic paper, it is special for the inspection paper drawn out from the magazine main body and adapted to the traveling path. A sufficient light-shielding effect can be obtained only by the existing light-shielding shutter on the side of the developing processing device without providing any light-shielding means. When the inspection sheet is pulled out from the magazine body, the inspection sheet is smoothly guided by the guide sheet, and the inspection sheet can be inserted and removed easily and appropriately, as in the case of insertion.

〔Example〕

An embodiment of the control strip magazine according to the present invention will be described below with reference to FIGS. In the figure, 1 is a pair of shells 1a, 1 which are vertically divided into two.
a'is fitted to each other to form a tubular shape, and a slit 1b is formed at one mating portion along the longitudinal direction of the tubular shape so that an inspection sheet described later can be inserted through the slit 1b. The magazine main body 2 is made of a soft light-shielding material such as sponge and / or a soft light-shielding cloth adhered to the light-shielding material, and is pressed against each other along both end portions of the slit 1b so as to close the slit 1b. The light shield 3 fixed in this state is arranged in the magazine body 1 so that one end is fixed along the edge of the slit 1b and the other end, which is a free end, has a spiral shape. The synthetic resin film-like guide sheets 4 are end caps which are attached to both end portions of the magazine body 1 and have support shafts 4a located on the axis of the magazine body 1 protruding therefrom. When the end cap 4 is attached to the magazine body 1, they are attached to each other by an appropriate click means (not shown). 5 is an inspection paper usually formed in a strip shape (for example, 88 × 306 mm), 6
Is a leader connected to one end of the inspection paper 6 by an adhesive tape 7 or the like, and 8 is an end cap 4 by a bearing portion 8a.
Slit 8b ₁ is that but has to be inserted into the longitudinal direction of the developing device side to one side of the rectangle 8b described later setting plate with rotatably supports the magazine body 1 deposited via a support shaft 4a The formed frame body 9 is a set plate disposed in the insertion portion of the development processing apparatus at a position closest to the traveling path of the photographic paper with reference to FIG. The magazine body 1 and the end caps 4 may be formed by vacuum molding using polyethylene or the like as a material. The material of the guide sheet 3 is preferably Teflon (trade name of polytetrafluoroethylene), nylon or the like, but polyethylene or polypropylene may be selected.

Since the control strip magazine according to the present invention is constructed as described above, when storing the inspection paper 5 in the magazine body 1 (this work is performed in the dark box with respect to the already exposed inspection paper 5). The inspection paper 5 which is inserted through the slit 1b through the space between the light shields 2 is guided while the leading end of the inspection paper 5 is in sliding contact with the smooth surface of the guide sheet 3 and is spirally inserted into the magazine body 1. Can be stored in. The guide sheet 3 allows the inspection sheet 5 to be easily and surely rolled up, and the volume of the magazine body 1 can be effectively utilized by storing the inspection sheet 5 in such a spiral shape, so that the magazine body 1 itself can be downsized. You can At the same time, it is possible to secure a sufficient amount of the inspection paper 5 to be stored. However, the stored inspection paper 5 has a spiral shape and both surfaces thereof are appropriately pressed by the light shield 2 in the slit 1b. As a result, it is completely shielded from light. Therefore, the so-called
There is no danger of fog exposure. The reader 6 projects from the slit 1b of the magazine body 1 containing the inspection paper 5, but since the magazine body 1 has a cylindrical shape, the above-mentioned protruding portion of the reader 6 is wound around the outer periphery thereof. This makes it easier to handle. FIG. 4 is an enlarged and detailed view of a portion surrounded by a one-dot chain line indicated by reference symbol A in FIG. 3, showing a traveling path of the printing paper P (indicated by a two-dot chain line). The set plate 9 is arranged in the immediate vicinity. When the control strip magazine is mounted in the development processing device, a door (not shown) provided on the side surface of the development processing device is opened, and the slit 8b ₁ of the frame 8 supporting the magazine body ₁ is developed. The set plate 9 is inserted from the side of the processing device. In this state, the magazine body 1 is rotatable via the support shaft 4a of the end cap 4, so that the reader 6 wound around the magazine body 1 can be easily unraveled. Next, the leading end of the leader 6 is manually inserted into the traveling path of the photographic paper P in the traveling direction thereof, and after confirming that the leading end of the leader 6 is fed by the feed roller, it is provided on the side surface of the developing processing apparatus. Close the open door. When the reader 6 is fed by the feed roller in this way, the inspection paper 5 stored in the magazine body 1 is pulled out and fitted to the traveling path of the printing paper P. Further, when the inspection paper 5 is pulled out from the magazine body 1 in this way, the guide sheet 3 smoothly moves from the state in which the inspection paper 5 is spirally stored in a manner opposite to the case where the inspection paper 5 is stored. In this case as well, proper and easy withdrawal is guaranteed. Thus, the inspection paper 5 is allowed to pass through the development processing solution in the development processing section, and the fatigue level of the development processing solution is inspected by the change in the color, density, etc. of the inspection paper 5. As described above, in addition to the control strip magazine itself being compact, a special device for guiding the inspection paper 5 to the running path for mounting the magazine in the immediate vicinity of the running path of the printing paper. It is not necessary to provide the above, and the development processing apparatus can be downsized.

By the way, the magazine body 1 and the end caps 4 can be formed by vacuum molding or the like, and in that case, not only the molding die but also a wooden die can be used, so that the manufacturing cost can be reduced, but the inspection in the magazine body 1 can be performed. Since the paper 5 is in direct contact with the smooth surface of the guide sheet 3,
The smoothness of the inner peripheral surfaces of the shells 1a and 1a 'of the magazine body 1 does not directly matter. Since the magazine body 1 and the like are made of synthetic resin, they are lightweight and can be assembled easily and reliably.

Needless to say, a specific size such as the length of the guide sheet 3 in the above embodiment can be selected as needed.

[Effect of device]

As described above, according to the present invention, a control strip magazine of this kind can be manufactured and assembled inexpensively and easily, and the magazine ensures smooth insertion / removal of the inspection paper to ensure easy and reliable handling. There are advantages such as being able to fit in.
In particular, although there are many restrictions in the design due to the demands for downsizing and high density of the photographic processing apparatus, the unique structure enables the work to be performed in this kind of dark box to be surely performed quickly. In addition, the control strip magazine itself and the development processing apparatus can be made compact.
