Abstract

(57) [Summary] [Purpose] To prevent a cartridge for winding the film from falling under its own weight when handling a film transport leader to which the leading end of undeveloped film is connected. [Structure] A notch 13 is formed at the end of a flexible leader body 11. A claw 15 is provided on the side edge of the notch 13. Connect the leading end of the film F pulled out from the cartridge P to the reader body 11 with a splice tape T, and engage the claw 15 with the inner periphery of the recess a provided in the end face of the cartridge P, so that the cartridge P is pulled out by its own weight. Prevent from falling.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is suitable for automatically developing photographed film wound into a cartridge. The present invention relates to a leader for transporting film used in

0002

[Conventional technology]

When developing film that has already been photographed using an automatic film processing machine, the flexibility is usually Connect the tip of the photographed film pulled out from the cartridge to the reader that has it, The above-mentioned leader is conveyed to the developing section of the automatic film processor in advance. .

0003 As shown in FIG. It is conventionally known that engaging holes 2 made of square holes are provided at equal intervals in the length direction. .

[0004]This leader _L1 and the film F pulled out from the cartridge P are connected to each other by a splice tape T.

[0005]

[Problem that the idea aims to solve]

By the way, since the conventional reader L ₁ does not have the function of holding the cartridge P, it is necessary to hold both the reader L ₁ and the cartridge P at the same time when setting the reader L ₁ in an automatic film processor. If you accidentally hold only one side, cartridge P or reader _L1 will fall under its own weight, and film F will be pulled out and exposed. Therefore, there is an inconvenience that handling of the reader _L1 is extremely difficult.

[0006] Therefore, this invention solves the above-mentioned inconvenience and has a function to hold the patrone in the reader. This makes it easier to handle the reader and prevents troubles from occurring. is a technical issue.

[0007]

[Means to solve the problem]

In order to solve the above problems, this invention uses a flexible reader book. A cutout is formed at the end of the body, and a cutout is provided on the side edge of the cutout on the end surface of the cartridge. A structure is adopted in which a claw is formed that can engage with the inner periphery of the recess.

[0008]

[Effect]

In the reader with the above configuration, there is a Connect the tip of the extruded film with splice tape, and also Engage the protruding piece on the edge with the inner periphery of the recess provided on the end face of the cartridge, and by this engagement to hold the cartridge and prevent it from falling due to its own weight.

[0009]

【Example】

Hereinafter, an embodiment of this invention will be described based on FIGS. 1 to 6. As shown in FIGS. 1 and 2, the belt-shaped leader body 11 is made of a material such as a synthetic resin sheet. It is formed from a flexible material, and has a large number of engagement holes 12 at two equal positions in the width direction. are provided at equal intervals in the length direction of the leader body 11.

0010 At the end of the leader body 11, a pair of left and right notches 13 are provided on both sides of the engagement hole 12. Two sets are formed. The distance between the outer edges 14 of the pair of engagement holes 12 is the same as that of the cartridge P. It is larger than its length and has claws 15 on its outer edge 14.

[0011] The reader shown in the example has the above structure, and when automatically developing the film, As shown in FIG. Connect the ends of the cartridge F by pasting splice tape T, and attach the cartridge P. are overlapped between a pair of notches 13, and the pawls 15 formed on the outer edge 14 of each notch 13 are It is engaged with the inner periphery of the recess a provided on both end faces of the Torone P.

0012 The cartridge P is engaged with the reader body 11 by the engagement between the claw 15 and the inner periphery of the recess a. Therefore, even if you hold only the reader body 11 by hand after connecting the film F, , Patrone P does not fall under its own weight and can prevent film F from falling off. , easy to handle.

[0013] The film F connected to the reader main body 11 is used for film development as shown in FIG. Insert the film into the film setting chamber 21 provided in front of the section 20, and insert it into the film setting chamber 21. Place the cartridge P on the cartridge stand 22 provided in the Insert the film into the film developing section 20 from between the lower pair of feed rollers 23, and let the film develop. The leader body 1 is rotated by the rotation of a sprocket (not shown) built into the image portion 20. 1 in the length direction, and develop the film F with the leader body 11 in advance. The sample is transported to the section 20.

[0014] Here, when sending the reader main body 11 to the film developing section 20, the concave part of the cartridge P is At step a, the engagement between the inner periphery and the claw 15 is released in advance. When disengaging the The Rone P should be pushed down, and the pushing down should be done manually. Alternatively, as shown in FIG. 4 and push it down with the plunger 25 of the solenoid 24. stomach. Also, attach a push-down member to the opening/closing lid of the film set 21, and close the opening/closing lid. By doing so, the cartridge P may be pushed down with the push-down member. .

[0015] 4 to 6 show other examples of the cutout 13 having the claw 15. Notch shown in Figure 4 The portion 13 has a rectangular shape large enough to fit a part of the outer periphery of the cartridge P, A claw 15 is provided on the holder.

[0016] The notch 13 shown in FIG. 5 has a rectangular shape that opens at the edge of the leader body 11. A pair of claws 15 are provided on both side edges.

[0017] Further, the cutout portion 13 shown in FIG. 6 is provided at a corner portion of the reader main body 11. A claw 15 is provided on the side edge.

[0018] The reader shown in FIGS. 4 to 6 has a part of the outer periphery of the cartridge 13 fitted into each notch. , engage the claw 15 with the inner periphery of the recess a on the end face of the cartridge P, and then press the cartridge P. Hold.

[0019] In the example, a reader capable of connecting two films was shown, but It may also be a reader that can connect one film.

[0020]

[Effect of the idea]

As described above, according to the reader according to this invention, a notch is formed in the reader body. , engage the claws provided on the side edges of the notch with the inner periphery of the recess formed on the end face of the cartridge. By aligning the cartridge, the cartridge is held in the reader body, so only the reader can be used. Even if you hold it in your hand, the patrone will not fall due to its own weight. Because of this, the film connects The reader is easy to handle, and there are no problems such as exposure due to film falling off. It is possible to prevent the occurrence of problems.
