Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a film winding magazine for winding and storing a film on which an image has already been taken from a cartridge, and for winding the film into this winding magazine. This invention relates to a film winding device, a leader necessary for guiding the film stored in this magazine to an automatic developing machine, and a film developing method for developing the film using the leader.

[Conventional technology]

In developing means that pulls out the film from the cartridge containing the film after an image has been taken and supplies it to the developing device, the cartridge and take-up magazine are brought into a darkroom and the film is wound into the magazine. . For this reason, it is not possible to quickly wind up the film from the cartridge into the magazine. Furthermore, since this film is directly attached to the winding shaft of the winding magazine and then wound, the work of attaching the film is also complicated.

Next, when the film is fed into an automatic processor, it is not possible to grasp the remaining development time until the leading edge of the film reaches the exit of the automatic processor, making efficient coordination with other tasks difficult. It is possible. There are two ways to guide the film inside the developing machine: a long, endless leader is passed in and out of the developing machine in advance, and the leading edge of the film is clipped to the leader, and the film is guided by clipping the leading edge of the film. In some cases, a short leader is attached to the container and the material is fed while being guided by this leader. However, when the leading end of the film is clipped to the leader, the film becomes unreliable due to the clip coming off. Further, when a short leader is used to guide the inside of the developing machine, a transport mechanism becomes complicated to prevent the leader from being blocked midway and causing transport failure.

[Problem to be solved by the invention]

In consideration of the above facts, the present invention provides a film winding magazine that can easily and quickly wind a film from a cartridge, a film winding device, a leader that can reliably guide the film into an automatic developing machine, and a film developing method. The purpose is to obtain.

[Means to solve the problem]

The film winding magazine according to the present application includes a magazine body whose interior is shielded from light, a winding shaft that is pivoted to the magazine body and rotates by receiving a driving force from outside the magazine body, and one end of which is connected to the winding shaft. It is characterized by having a long leader for developing and transporting which is locked and whose other end is used for locking the film, and a slit formed in the magazine body through which the leader and film pass through while maintaining the light shielding state of the magazine body. It is said that

For this reason, in this winding magazine, the tip of the photographed film is connected to the other end of a long leader protruding from the magazine body using adhesive tape, and when the winding shaft of the magazine body is rotated, the leader is attached to this winding shaft. As it is wound up, the photographed film is also pulled by this leader and stored into the magazine body. Therefore, the leader is wound on the inner circumference of the winding shaft, and the photographed film is wound on the outer circumference.

The film winding device according to the present application is a film winding device that pulls out and winds a film from a cartridge into a magazine body whose interior is shielded from light, and includes a device body that can accommodate the magazine body and is openable and closable. , a through hole provided in the device main body through which the winding shaft protrudes from the magazine main body, a support means provided in the device main body to support the parrone, and a support means provided in the device main body to be pulled out from the cartridge. The magazine is characterized in that it has a splice table that connects the leading end of the film and a leader that is connected to the winding shaft and whose leading end is pulled out from the magazine body.

This film winding device accommodates a film winding magazine into an open device main body, and places the tip of a leader pulled out from the magazine main body onto a splice table. On the other hand, the leading end of the film pulled out from the cartridge is aligned with the leader on the splicing table and joined using adhesive tape or the like. Here, when the main body of the device is closed and the cartridge is supported by the support means and the winding shaft is rotated,
The film is wound onto the shaft of the magazine body while being pulled by the leader.

The leader according to the present application is a leader that is fed into an automatic film processing machine prior to a developing film, and is automatically placed at a first predetermined position in the longitudinal direction or a connected film at a second predetermined position in the longitudinal direction. It is characterized in that the time required for the developing machine to reach the third predetermined position is displayed.

For this reason, when the leading end of the film is glued to a leader and the leading end of the leader is fed into an automatic developing machine, the leader guides the film into the developing machine. This reader displays the time it takes for the film to reach the exit of the automatic processor at a predetermined position in the horizontal direction, so the operator can easily judge the remaining time until the film finishes developing. I can do it.

The film developing method according to the present application is a film developing method in which a film is sequentially immersed into a plurality of processing tanks for development processing, and includes a leader having a length equal to or longer than the total transport path length of the plurality of processing tanks. It is characterized by being conveyed through the processing tank by alternately connecting the film with the film.

Therefore, even if one end of the leader protrudes downstream from the outlet of the automatic developing machine, the other end protrudes further upstream from the upstream side of the automatic developing machine. Therefore, the leading edge of the film can be connected to the rear end of the leader while the leader spans the entire transport path of the automatic processor. As a result, the film is reliably fed into the automatic developing machine as the leader moves, and the leader and the film are not blocked in the automatic developing machine.

[Embodiments of the invention]

FIG. 1 shows an automatic processor 10 to which the present invention is applied. In this automatic developing machine 10, a developing tank 12, a bleaching tank 14, a fixing tank 16, a washing tank 18, and a drying section 22 are arranged from the first stream side to the downstream side according to the flow of the developing film F. After being immersed in a treatment tank in sequence, they are taken out and processed.

Note that transport racks (not shown) are inserted into these processing tanks to sandwich the film and provide driving force. A film winding device 24 is shown in FIG.

This film winding device 24 includes a lower case 26 and an upper case 2.
8 forms the main body of the device. As shown in FIG. 3, the lower case 26 has a box shape with an open top end.
A rib 32 protrudes from the inner periphery of the upper end, and by fitting the periphery of the opening of the upper case 28 to the outside of the rib 32, the film winding device 24 is closed as shown in FIG.

A rib 34 protrudes from the bottom of the lower case 26.
A film winding magazine 36 is housed and positioned on one side of the film 6. This film winding magazine 36 has a cover plate 42 that is tightly attached to the opening of a lower case 38 whose upper end is open, thereby forming a magazine body whose interior is in a light-shielded state. A slit is formed between the end of the cover plate 42 and the projecting piece 44 that projects horizontally from the upper end of the lower case 38, through which the leader and film pass. A flexible material (not shown) such as telesive is pasted on the slit to maintain the light-shielding state and prevent damage to the film and reader.

This film winding magazine 36 is connected to the film winding device 24.
When the upper case 2 is in the closed state, as shown in FIG.
The bracket 46 is integrally disposed inside the lower case 8 and is pressed against the bottom surface of the lower case 26.

Further, as shown in FIG. 1, this magazine 36 is disposed on the most upstream side of the automatic developing machine 10, that is, corresponding to the entrance of the film F (arrow A). That is, the film winding magazine 36 can be mounted on the bracket 48 projected from the upstream end of the automatic developing machine 10, and the protruding piece 44 can be made to correspond to the artificial part A. It is also possible to provide means (not shown) for fixing the film take-up magazine 36 in this state.

As shown in FIG. 3, a splice table 52 is fixed to the lower case 26 of the film winding device 24 in correspondence with the projection 44 of the film winding magazine 36. This splice table 52 is arranged at the same height as the projecting piece 44, so that the leading end of the leader pulled out from the film winding magazine 36 and the leading end of the film F pulled out from the cartridge P are arranged opposite to each other. It has become.

The cartridge P is a support bracket 54 disposed on the opposite side of the film winding magazine 36 in the film winding device 24.
It is now being installed in the

The lower end of the support bracket 54 is pivotally supported on the lower case 26 by a pin 56, and a pair of arms 57 are protruded in parallel from the upper end. This arm 57 has an arcuate notch 58 formed at its tip, and accommodates 1/2 of the outer circumference of the axial end of the cartridge and 1/2 of the outer circumference of the cartridge core S, respectively.

The cartridge P swings together with the support bracket 54 about the pin 56, and can be moved toward and away from the film winding magazine 36. However, when the upper case 28 is fixed to the lower case 26, the other half of the outer circumference is pressed against the support bracket 54 by the bracket 62 for preventing rotation of the cartridge projected from the upper case 28, and The protruding portion 64 is pressed against the splice table 52, so that the swinging of the cartridge P is restricted and rotation is prevented.

As shown in FIG. 4, a winding shaft 66 pivotally supported at the center of the film winding magazine 36 passes through the lower case 38, and a ring 68 is attached to this penetrating portion. A handle 72 is coaxially fixed to this ring 68 and is used for inputting rotational force by the operator. In place of the handle 72, a coupling means such as a coupler for coupling to a drive source such as a motor may be provided. A ring groove 74 is formed on the outer periphery of the ring 68, and a ring groove 74 is formed on the outer periphery of the ring 68.
The film winding device 24 is inserted into the film winding device 24 by inserting a semicircular notch formed in each joint surface and forming a through hole 75 (FIG. 4).
The handle 72 is made to protrude to the outside of the film winding device 24 while keeping the inside thereof in a light-shielded state.

FIG. 7 shows a plan view of the reader L.

This leader L has a length β from the tip LT to the rear end LE.

is set to be equal to or greater than the total film transport length from the inlet A to the outlet B of the developing machine 10. Therefore, this reader L
In a state where the leading end LT projects further downstream than the exit section B in the film transport direction, the rear end LE projects further upstream than the entrance section B.

In this case, the artificial part A of the developing machine 10 is the upstream side in the film transport direction from the film entrance to the developing tank 12, and the exit part B is the final processing step of the developing process. It is also preferable that it is on the downstream side.

Indications 76 are attached to the leader L at predetermined positions, for example, seven positions along the length from the tip LT. This display 76 displays the time from when the display 76 passes through the exit section B until the predetermined position of the leader L, for example, the rear end LE, reaches the exit section B. This time is calculated in advance from the length 1□ from the display 76 to the rear end LE of the leader and the film conveyance speed of the developing device 10. A display 77 that similarly indicates the time that the rear end LE passes (naturally, a time different from the display 76) may be attached to another position of the display 76.

Note that these times are not limited to the time when the rear end LE of the leader passes the exit section B, but also when other positions of the leader L or a specific position of the film F (for example, the first frame position) pass the exit section B. It may be the time, or it may be the time until it passes through a predetermined position other than the exit part B.

Next, the function of this embodiment will be explained.

Inside the film winding magazine 36, the leader is removably secured in advance with a clip, adhesive tape, etc. so that it can be pulled out by strongly pulling the tip of the leader toward the outer periphery of the winding shaft 66. The other end of this leader is made to protrude to the outside of the film take-up magazine 36.

In this state, the film take-up magazine 36 is housed in the lower case 26 in the arrangement shown in FIG.

At the same time, a cartridge P is mounted in the arcuate notch 58 of the arm 57. In this state, the arm 57 can pivot around the pin 56. The leading end of the film F pulled out from the cartridge P is joined to the leading end of the leader using adhesive tape or the like.

Here, the upper case 28 is fitted onto the lower case 26, and the film winding device 24 is brought into a closed state. By rotating the handle 72, the winding shaft 66 beam L is wound up. In this state, the bracket 62 is already attached to the cartridge P.
Since the cartridge protrusion 64 is pressed against the splice table 52, the cartridge P does not rotate. The leader L applies a tensile force to the film F in the longitudinal direction to smoothly pull out the film F from the cartridge P and wind it onto the winding shaft 66. With the film F unwound to the end, the upper case 28 is removed from the lower case 26, and the end of the film F is cut from the core S of the cartridge.

Thereafter, the film winding device 24 is opened, and the film winding magazine 36 is moved to the automatic developing machine 1 as shown in FIG.
Set it to 0. In this state, the reader attached to the previously processed film is placed across from the input section A of the automatic processor 10 to the exit section. Therefore, one end of the film F pulled out from the magazine 36 installed in the automatic developing machine 10 is joined to this leader.

Here, when driving force is applied to the automatic developing machine 10, the film F is developed while being pulled by the leader used in the previous development, and the leader in the magazine 36 connected to this film F is transferred into the developing machine 10. Pull in. In this case, the seventh
As shown in the figure, the time required for the film to reach the cartridge is displayed in advance in the middle part of the reader, so the operator can check the leading edge of the film F etc. by visually observing these displays 76 and 77 at the exit part. It is possible to determine the remaining development time until the sample reaches the exit section.

When the development of the film F in the film winding magazine 36 is completed and it is taken out from the drying section 22, the tip LT of the reader L in the film winding magazine 36 is pulled by the film F and reaches the exit part of the automatic developing machine 10. pulled out to B. Therefore, the reader L is in a state where it is spread over the entrance section A and the exit section B.

When the film take-up magazine 36 is removed, the rear end of the leader L is pulled out from the magazine, and by pulling strongly, the end comes out. The already developed film F is also separated from the leader L and carried to a subsequent process such as a printing device.

Thereafter, by repeating the above-mentioned operations, the development work is sequentially performed.

〔Effect of the invention〕

The present invention has the above-described structure, and has excellent effects in that the film can be easily and quickly wound up from the cartridge into the winding magazine, and the film can be reliably guided into the developing machine.
