Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a photographic process in which a film is connected to a thin-walled leader, and the developed film is sequentially positioned at a predetermined position on a negative carrier for printing processing. Regarding equipment.

[Prior art]

There is a developing device in which photographed film is fed into the developing device by a film feeding device (Japanese Patent Application Laid-Open No. 1983-1999).
58445, Japanese Patent Application Laid-open No. 6361250)
.

In this device, the film is connected to the rear end of a thin leader made of synthetic resin, and an engagement hole formed in this leader engages with a transport sprocket in the developing device to receive driving force and transport the film in the developing device. It is now possible to do so.

Therefore, a plurality of leaders are stacked and housed in the magazine with a leader attached to the leading end of the film in advance. When the leader receives a driving force and is transported, the film is simultaneously subjected to development, fixing, washing, and drying processes.

By the way, when printing on photographic paper is performed continuously after the above development process is completed (simultaneous printing), the printing device
Since the negative film has a single guide path, in the case of simultaneous printing, the development processing must be performed in accordance with the printing processing speed.

Generally, the printing processing speed is faster than the developing processing speed, so after developing negative films are stocked, the printing operation is performed using these films.

[Problem to be solved by the invention]

However, negative film is long and requires a fairly large area to be stocked, and it is preferable that the order in which it is transported to the printing device matches the development processing order.
It becomes necessary to manage the order of development processing, which becomes complicated.

The present invention has been made in consideration of the above facts, and an object of the present invention is to obtain a photographic processing apparatus that can compactly stock film after processing without managing the order of processing and improve work efficiency. .

[A means of promise to solve problems]

A photographic processing apparatus according to the present invention connects a film pulled out from a cartridge to a thin leader, engages an engagement protrusion into an engagement opening formed in the leader, and drives the engagement protrusion to separate the leader and the film. A photographic processing device that performs printing by positioning the image frames recorded on the film at a predetermined position on a negative carrier after being transported and subjected to development processing, and connected to the leading edge of the film after development processing is completed. A stacking box that stacks the loaded leaders in layers, a roller that penetrates the bottom of the stacking box and whose circumferential surface is in contact with the bottommost leader, and the printing process of the film before the bottommost leader is completed. and a driving means for driving the roller at the time to apply a conveying force to the lowest layer leader.

[Effect]

According to the present invention, when the film development process is completed, the leader connected to the leading end is accumulated in the accumulation box. At this time, the leaders are accumulated from the bottom layer in the order of development processing.

Therefore, even if the previous film is in the printing process,
Subsequent films can be kept in stock, and development processing can be performed regardless of the printing processing time. Therefore, even in the case of simultaneous printing, the work can be performed in the same way as the development process alone, and work efficiency is improved.

When the printing process for the previous film is completed, the roller is rotated by the driving force of the driving means. This rotational force acts as a conveying force for the bottom layer leader, and the leader is conveyed along with the connected film toward the printing position. Here, since the readers are stacked from the bottom layer in the order of the development process, the printing process can be performed in the order of the development process without any supervision by the operator.

FIG. 1 shows a photographic processing apparatus 10 according to this embodiment.

The photographic processing apparatus 10 has a recess formed in its side surface, which serves as a loading opening 14 for the magazine 12.

A film supply device 16 is provided downstream of the insertion port 14 . The film supply device 16 also includes a developing device 1.
8 are attached.

As shown in FIGS. 2(A) and (B), the magazine 12
A plurality of cartridges 22 are housed in which the photographed negative film 20 (hereinafter simply referred to as negative film 20) is wound up in layers.

The cartridges 22 are arranged in two rows, and the leading ends of negative films 20 pulled out from adjacent cartridges 22 are connected to one leader 24 via an adhesive tape 26.

The leader 24 has a thin plate shape and is flexible, and a plurality of leaders 24 are arranged in layers within the magazine 12.

Holes 28 are provided in the center of the width direction of the leader 24 at regular intervals along the longitudinal direction, and correspond to engaging protrusions 34 formed on an endless conveyor belt 32 wound around a pair of rollers 30. (One roller is not shown). A gear formed on the outer circumference of the roller 32 engages with constant-spaced protrusions 32A protruding from the inner circumference of the endless conveyor belt 32.

Here, when the roller 30 rotates and the endless conveyance belt 32 is driven, the leader 24 is conveyed together with the endless conveyance belt 32.

As shown in FIG. 1, in the film supply device 16, a pair of rollers 36 are arranged along the conveying direction, and an endless conveying belt 38 is wound around the pair of rollers 36.

An engaging protrusion 40 is formed on the outer periphery of the endless conveyor belt 38, similar to the endless conveyor belt 32, and the tip of the leader 24 passes through the side wall 42 and engages with the engaging protrusion 40. The leader 24 is conveyed to the developing device 18. In the developing device 18, the conveyed negative film 20 is subjected to development, fixing, washing, and drying processes. Above the film supply device 16 and the developing device 18
A films dock section 46 is disposed downstream of the film docking section 46 .

The film stock dock section 46 is box-shaped and has an opening 48 formed on the side surface facing the developing device 18 . For this reason, the rollers 24 discharged from the developing device 18 are sequentially stacked in layers. Further, the negative film 20 connected to the rear end of the leader 24 hangs downward from the opening 48 of the film stock dock section 46 and is stored.

A slit hole 52 is provided at the lower end of a side surface 50 of the film stock dock section 46 opposite to the opening 48 . Further, a rectangular through hole 54 is provided in the bottom surface of the film stock dock section 46, and a portion of the roller 56 projects inward of the film stock dock section 46 and is pivotally supported. When this roller 5G is rotated by the driving force of a driving means (not shown), it applies a conveyance force to the lowest layer leader 24 housed in the film stock dock section 46.

As shown in FIG. 3, a negative carrier 62 of the printing device is disposed downstream of the film stock dock section 46 via an endless conveyor belt 60 wrapped around a pair of rollers 58 (see FIG. 1). ing. The negative carrier 62 has an insertion port 6.
A printing position is provided for printing the image on the film sent from 4, and printing light from a light source (not shown) (Fig.
A through hole 66 is provided (see FIG. 4) for irradiating an image onto photographic paper (not shown) with a dotted chain line representing an optical axis L). The insertion opening 64 is aligned with one of the conveyance paths for two negative films conveyed in parallel.

A cutter 68 is disposed between the upstream reversing section of the endless conveyor belt 60 and the films dock section 46. This cutter 68 is activated when the rear end of the leader 24 passes and the leading end of the negative film 20 (the fogged part with no image frame) passes.
0 are separated from each other. In this case, both ends of the two negative films 20 in the width direction are held between the rollers 70 and the film guide surfaces. This roller 70 constitutes a loop forming means and can be driven independently corresponding to each negative film 20.

Further, as shown in FIG. 6, a hole 72 is provided between the downstream reversing portion of the endless conveyor belt 60 and the negative carrier 62, and a guide block 74 is provided corresponding to the hole 72. .

The guide block 74 is inserted into a shaft 76 whose axial direction is the width direction of the negative film 20 . The guide block 74 is rotatable about the shaft 76 by the driving force of a driving means (not shown). Further, a guide rod 78 is integrally formed with the guide block 74. The guide rod 78 has a longitudinal dimension longer than the width direction dimension of the guide block 74, and protrudes toward the lower right in FIG. 6.

Here, when the cutter 68 cuts the piece 24 or the piece 24 is conveyed by the endless conveyor belt 60, the guide block 74 is rotated upward as shown by the imaginary line in FIG. Therefore, the guide rod 78 is
4, the leader 24 is bent and guided to the hole 72, and is discarded.

A guide path 80 is formed on the top surface of the guide block 74. This guide path 80 is provided with rollers 82 at both ends thereof in the width direction, which together with the roller 70 constitute a loop forming means. The rotating shaft 84 of the roller 82 is supported by a bracket 86 erected from the guide block 74, and the rotating shaft protruding from one bracket 86 is connected to a motor 88.
It is coaxially connected to the rotating shaft of.

A circular arc surface coaxial with the shaft 76 is formed at the lower end of the guide block 74, and is accommodated in a concave surface provided in the support block 90. The support block 90 and the guide block 74 are not separated from each other and are able to rotate relative to each other when the guide block 74 rotates.

Both ends of a wire 92 are secured to both side surfaces of the support block 90. The wire 92 is wound around a pair of pulleys 94 and has a loop shape. The rotating shaft 96 of one pulley 94 is the rotating shaft of a motor 98, and the rotation of the motor 98 moves the wire 92 in the axial direction, and accordingly moves the guide block 74 along the shaft 76. It has become.

Thereby, the guide path 80 can be selectively moved to a transport position for one negative film 20 and a transport position for the other negative film 20 that are transported in parallel. Here, in this embodiment, since the two negative films 20 are arranged in parallel, the guide block 74 can take two positions, and the stoppers 99 provided near both widthwise ends of the guide block 74 (only one (as shown in the figure), the stopping position is determined.

When the negative film 20 is placed in a position different from the guide path 80 of the guide block 74 and the insertion opening 64 of the Henega carrier 62, the rotation of the roller 82 on the guide path 80 side is temporarily stopped, and only the roller 70 is allowed to rotate. ing.

Therefore, the negative film 20 is bent in a loop shape between these rollers 70 and 82 (see FIG. 5), and the guide block 7
4. Prevents it from bending when moving.

The operation of this embodiment will be explained below.

When conveying force is applied to the leader 24 loaded in the magazine 12, the cartridge 22 also moves under tension via the film. When the cartridge 22 is placed in a predetermined position, the movement of the cartridge is stopped and the reader 24
The negative film 20 is pulled out from the cartridge and transported to the developing device 18. In the developing device 18, the negative film 20 is subjected to development, fixing, washing, and drying processes.

The leader 24 discharged from the developing device 18 is accommodated in the film stock dock section 46, and the negative film 20 continued at the rear end is held in a hanging state. The leaders 24 pass through the developing device 18 one after another and reach the film stock dock section 46, where they are stacked. In this case, there is no need to synchronize with the downstream printing process, and the developing process can be performed independently at a desired processing speed. Further, since the hanging negative films 20 have been dried, problems such as sticking to each other do not occur.

When the lower roller 58 of the film stock dock section 4 is driven, only the bottom layer gluer 24 is conveyed, and the slit hole 5
It is discharged from 2. When the rear end of the leader 24 discharged from the slit hole 52 reaches a predetermined position, the cutter 68 is activated. When the cutter 8 operates, the leading end of the negative film 20 is cut, and the leader 24 and the two negative films 20 are separated (see FIG. 3).

The separated leader 24 is further conveyed by an endless conveyor belt 60. At this time, the guide block 74 is rotated around the shaft 76 to the position shown in the imaginary line 3 in FIG. and is guided to the hole 72 and discarded. reader 2
4 is discarded, the guide block 74 rotates about the shaft 76, and the guide path 80 coincides with the film transport path (see the solid line position in FIG. 6).

Here, the roller 70 rotates, and the negative film 20 on the side whose transport path matches the insertion opening 64 of the negative carrier 62 starts transporting. The leading edge of the negative film 20 is the guide path 80
When entering the negative film 20 , the negative film 20 is held between the rollers 82 and moved to the negative carrier 62 by the driving of the rollers 82 .
is guided and conveyed to the insertion port 64 of. Here, the image frames are sequentially positioned at the printing position on the negative carrier 62, and the printing process is performed one after another (see FIG. 4).

When the printing process for one negative film 20 is completed, the motor 98 is driven and the wire 92 is moved in the axial direction. Accordingly, the guide block 74 moves in the axial direction of the shaft 76 to a position where it contacts the stopper 99. In this state, the guide path 80 coincides with the conveyance path of the negative film 20 being transported downstream of the film stock dock section 4G.

Here, when the roller 70 is driven and the leading edge of the negative film 20 is held between the rollers 82 of the guide path 80, the rollers 82
rotation is stopped, but the roller 70 continues to drive. As a result, the negative film 2 is moved between the rollers 70 and 82.
0 is curved into a loop shape (see Figure 5).

In this state, the guide block 74 is moved again and the guide path 8
0 and the insertion opening 64 of the negative carrier 62. At this time, the negative film 20 is twisted in the width direction, but since it is curved in a loop shape, there is no problem such as bending. When the guide block 74 is aligned with the insertion opening 64,
The roller 82 on the guide path 80 and the roller 70 on the fixed path are driven, and the negative film 20 is conveyed while maintaining a loop, and is subsequently positioned to the printing position in sequence in the same manner as the single-shot negative film 20. .

In this way, in this embodiment, two negative films 20 are installed and developed at the same time, and one film is used during the printing process.
Since the negative film 20 of the book is placed on standby and the printing process is performed serially, it is possible to process the negative film side by side even when developing negative film that requires simultaneous printing, improving work efficiency. can. Furthermore, since the printing position is fixed, the structure is simple and the optical axis will not shift and affect the quality of the printed image.

In this embodiment, after the leader 24 is cut and separated from the negative film 20 by the cutter 68, the guide block 74 is rotated about the shaft 76, and the guide block 74 is disposed of into the hole 72 provided below. However, the structure may be such that the leader 24 is discarded immediately after being cut. The configuration will be explained in detail below.

As shown in FIGS. 7(A) and 7(B), a box 100 is integrally attached to the upper end of the kakuro 8. This box body 100 is configured to move together with the cutter 68 when the cutter 68 is activated. The box body 100 includes
A slit hole 102 is formed along the conveyance direction of the negative film 20.
is formed and passes through both sides. A hole 104 is provided at the bottom of the box 100 and serves as a waste guide hole for the reader 24. The lower end of the box 100 is normally located above the conveyance guide path of the negative film 20, and the leader 24 conveyed from the film stock dock section 46 is attached to the box 100.
It will pass below 00 (see Figure 7 (A))
. Although not shown, the leader 24 is supported by a support plate that moves together with the box 100, and is maintained in a horizontal state. Here, when the cutter 68 is activated and reaches the lowest end, the leader 24 slides down from the hole 104 and is discarded. At the same time, the slit hole 10
The bottom surface of the negative film 20 is flush with the conveyance guide path of the negative film 20 (see FIG. 7(B)), and this position is maintained until the rear end of the negative film 20 passes.

In this way, since the leader 24 is discarded at the same time as the kakuro 8 is operated, and the transport guide path for the negative film 20 is formed by the slit hole 102, there is no need to rotate the guide block 74, and the structure is simplified. Become.

〔Effect of the invention〕

As explained above, the photographic processing apparatus according to the present invention has the excellent effect of being able to compactly stock film after processing without managing the order of processing, and improving work efficiency. .
