[0001]
BACKGROUND OF THE INVENTION
The present invention relates to Hol dust for the control strip, more particularly, it is formed a storage space for accommodating a sheet-like control strip, and a slit to allow the loading and unloading of the housing has been control strip to the housing space in the holder body about the Hol da for the control strip.
[0002]
[Prior art]
As an apparatus for processing the control strip, there is an apparatus disclosed in JP-A-6-35156, and in this conventional technique, the control strip is accommodated with the tip exposed to about 50 mm with respect to the holder. This consholder is set on the part of the conveyor belt that conveys the photographic paper in a suctioned state by negative pressure, and the conveying force from the conveyor belt is applied with the tip of the control strip adsorbed by the suctioning force of the conveyor belt. Thus, the control strip is pulled out and sent to the developing machine.
[0003]
Further, the conventional development processing apparatus is provided with a transport means having a large number of transport rollers so as to send the photosensitive material to a plurality of development processing tanks for performing the development processing, and the control strip is sent to the upper transport position of the transport means. A forgiving supply is formed. When the control strip is fed from the supply section, after the operation of storing the control strip in the holder or the like, the operation of attaching the leader to the tip of the control strip with the splicing tape is performed, and the holder is supplied to the developing device. By setting to the section, the leader is drawn into the conveying means inside the development processing apparatus, and as a result, the control strip is sent to the development processing tank together with the leader.
[0004]
[Problems to be solved by the invention]
Considering the work of storing the control strip in the holder, etc. as described above, control is performed by applying a relatively strong force in the dark box or dark room, as described in the disadvantages of the prior art cited in the publication number. In addition to the work form for inserting the strip, it was also necessary to attach a leader to the tip of the control strip, which was difficult. In the case of using the leader in this way, it is necessary to remove the leader from the control strip prior to the work of measuring the density of the control strip after development, and there is room for improvement in terms of labor. Therefore, it is conceivable to adopt a configuration that enables the feeding of the control strip using the transport force of the transport belt of the development processing apparatus, as in the prior art cited in the publication number. Since it is large in size, it is necessary to open the development processing apparatus and set it at the site of the conveyor belt even when it is used, which is troublesome.
[0005]
Also, in consideration of handling when the control strip stored in the holder or the like is sent from the supply unit of the development processing device to the conveying means inside the development processing device, conventionally, by setting the holder or the like to be pushed into the supply unit, The end of the holder fits into the supply section and reaches the state where the intrusion of light into this end is blocked, and is conveyed to the tip of the reader attached to the tip of the control strip at approximately the same timing as this. A conveying force acts from the conveying roller of the means, and the control strip is pulled into the developing processing apparatus together with the leader by the conveying force. However, if the reader attached to the tip of the control strip is longer than the appropriate length, when setting the holder or the like to the supply unit, the transport roller is placed on the tip of the reader before the holder or the like is completely pushed into the supply unit. As a result, the control strip is pulled out at a timing when the light beam is not completely blocked, resulting in inconvenience of exposing the control strip. On the contrary, if the reader is shorter than the proper length, the control strip cannot be sent to the development processing apparatus even if the holder is completely set in the supply unit. There is a demand for a technique for reliably feeding the accommodated control strip to the development processing apparatus.
[0006]
An object of the present invention is to reasonably configure the housing of the control strip, the feed and the easily control strip for Hol da.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First embodiment]
As shown in FIGS. 2 and 4, the holder body 1 having a front wall 1A and a back wall 1B and functioning as a dark box is formed of a resin material, and communicates with the storage space R of the holder body 1; A slit S enabling insertion and delivery of the sheet-like control strip CS is formed at one end, and a flange portion 1F is integrated with the outer surface of the holder body 1 on the side where the slit S is formed. A rubber roller 3 that rotates integrally with the support shaft 2 is provided inside the bulging portion 1C that is formed on the side of the front wall 1A as a conveying body, and a knob 4 that rotates the roller 3 is supported as an artificial operation body. A control strip holder is provided at the end of the shaft 2.
[0014]
In this holder, a notch 1D that is slightly wider than the width of the control strip CS is formed at the end of the front wall 1A on the side where the slit S is formed. The light shielding material 5, 5 such as black cloth or black felt is stretched on the inner surfaces of the front wall 1A and the back wall 1B across the portion to prevent the light from entering the storage space R.
[0015]
The light shielding materials 5 and 5 have a function of preventing the intrusion of light rays and a function of assisting the sliding of the control strip CS. The distance between the opposing surfaces of the light shielding materials 5 and 5 is controlled by the control strip. The light shielding performance is enhanced by making the thickness approximately equal to the thickness of CS.
[0016]
When inserting the control strip CS into the control strip holder, use a dark box or dark bag, or set the control strip holder in the dark room with the notch 1D facing upward and control. With the photosensitive surface of the strip CS facing upward, the end of the control strip CS is pushed from the slit S to a position in contact with the roller 3, and the knob 4 is artificially rotated to rotate the control strip by the rotational force of the roller 3. The control strip CS is drawn into the storage space R by applying a moving force to the CS.
[0017]
In this way, when the control strip CS stored in the control strip holder is sent to the development processing apparatus for development processing, the following procedure is followed. That is, as shown in FIG. 1, the development processing apparatus cuts a photographic paper (not shown) from the photographic paper magazine 10 into a print size, and then exposes the photographic paper after exposure at the exposure unit 11. It is configured to be sent to the development processing unit 13 by the mechanism 12 and sent to the upper surface of the apparatus after drying. In this development processing apparatus, the development processing unit 13 is provided with a plurality of development processing tanks 13A, and a rack 15 having a large number of pressure-bonding rollers 14 is disposed so as to send photographic paper to each of the development processing tanks 13A. A supply unit F is formed on the upper surface of the case 16 at a position corresponding to the upper transfer position of the transfer means.
[0018]
As shown in FIG. 3, the supply unit F includes a detachable lid 18 and forms a vertical cylindrical portion 19 having an opening 20 at the upper end with respect to a space opened and closed by the lid 18. It is a simple structure.
[0019]
Therefore, when the control strip CS is fed into the development processing apparatus, the conveying means is driven in advance, and after removing the lid member 18, the end of the holder for the control strip with respect to the opening 20 as shown in FIG. Insert the part. In the state of being inserted in this way, the position of the holder body 1 is determined by the flange portion 1F of the holder body 1 coming into contact with the opening 20, and at the same time, the flange portion 1F covers the upper portion of the opening 20 to enter the opening. In this inserted state, the knob 14 is rotated to rotate the roller 14 to apply a moving force to the control strip CS. Therefore, the leading end of the control strip CS moves the conveying means by the guide G. Then, the control strip CS is guided to each of the development processing tanks 13A by the conveying means and is subjected to development processing. When the control strip holder is inserted into the opening 20, the posture in which the knob 4 provided in the holder body 1 is located on the near side as viewed in the direction of FIG. 4 is appropriate. The posture can be easily determined, and the knob 4 can be easily operated from the front side by setting the posture in this proper posture.
[0020]
As described above, in the first embodiment, when the control strip CS is inserted into the storage space R of the control strip holder, the control strip CS is smoothly drawn by simply rotating the knob 4 so that the work is performed. In addition to the ease of operation, the labor is reduced, and when the control strip CS is sent to the development processing apparatus, the knob 4 is simply rotated and the operation is simplified. Further, by using the holder for the control strip of the present invention, it is possible to remove the splicing tape after the work of attaching the leader to the front end portion of the control strip CS with the splicing tape or the developing process without the need for the leader. No work is required and the work is extremely easy. In particular, since the roller 3 is disposed on the photosensitive surface side of the control strip CS, when the control strip CS is sent, it eliminates the inconvenience of scratching the photosensitive surface, and the photosensitive surface having a slight viscosity is made of rubber. A reliable feed is realized by contacting the roller 3.
