2. Description of the Related Art In recent years, a method has been studied in which a negative film that has undergone development processing is not cut, but is wound long and wound on a spool of a negative film container (hereinafter referred to as a cartridge) such as a cartridge and returned to a customer. This eliminates the need for the work of cutting to a predetermined length and the complicated work of connecting the piece negatives when reprinting.

[0003]

However, when the developed negative film is wound into a cartridge and accommodated therein, and a long time has passed, the negative film has a certain curl. For this reason, when the negative film is pulled out for additional printing, it may be curled and the work may be difficult.

Further, in order to remove the curl habit, it may be possible to wind the roller around the roller in the reverse curl direction. However, the number of steps for removing the curl increases, and the image surface may be damaged during the operation for removing the curl. Absent.

Such a problem is caused especially by the negative film 1
This may occur during work in a so-called minilab, where each book is processed. On the other hand, in a large laboratory, since a large amount of film is processed by an automated device, for example, even if a means for removing curl habit is added, workability is not particularly deteriorated. Defects are unlikely to occur.

In view of the above facts, the present invention is a manual film carrier capable of reliably positioning a photographic film having a curl tendency at a printing position during manual work (manual handling) and maintaining its flatness. The purpose is to obtain.

The operation of this embodiment will be described below. For example, when an order for reprinting is made, the customer specifies the image to be reprinted. For example, a frame number assigned to an image frame is designated, or if there is an index print, a corresponding portion (for example, frame number) of this index print is marked.

In this way, the image is specified, and the cartridge 52 in which the developed negative film 24 is accommodated
Hand over and ask for work.

Here, with the printer processor 10,
In a so-called minilab, the cartridge 52 is loaded in the loading section 54 of the negative carrier 22 according to this embodiment.

That is, the opening / closing lid 58 is opened and the loading section 5 is opened.
4, and the opening / closing lid 58 is closed. In this state, the cartridge 52 is fixed to the fixed shaft 60 and the spool driver 70.
The door driver 74 is positioned while being supported by the door 66, and the door driver 74 is connected to the rotary shaft 68 integrated with the door 66.

Next, the door 66 of the cartridge 52 is opened by rotating the door driver 74. As a result, the negative film 24 can be pulled out.

Then, the operating knob 72 is operated to rotate the spool 62 in the negative film drawing direction via the spool driver 70. By this rotation, the negative film 24 sequentially passes through the opening 64 from the uppermost layer and is conveyed between the plate members 76 and 78. Here, the plate material 7
Since the telem 80 is provided between 6 and 78,
When the negative film 24 is conveyed, there is no contact with the plate members 76 and 78, and scratches are prevented.

Here, since the negative film 24 is wound in the cartridge 52 for a long period of time, it has a curl, and if left unattended, it will curl up.
However, in this embodiment, since the narrow gap between the plate members 76 and 78 is passed, curling does not occur, and the plate members 76 and 78 can be conveyed in a flat state.

On the other hand, the leading edge of the negative film 24 is the accommodating portion 8
When reaching 2, the tip end portion is wound around the reel 84 of the accommodating portion 82. That is, the negative film 24 has a curl, and the curl occurs when the plate material 76, 78 that has been straightened in the accommodating portion 82 is released. This curl causes the reel 84 to be wound. Further, since the reel 84 is rotated by the operation of the operation knob 72 transmitted via the belt 88,
The negative film 24 is sequentially wound around the reel 84.

A printing mask is provided at the center of the plate members 76 and 78, and the operator positions a desired image frame in the mask opening (rectangular hole 92). This positioning operation can be easily performed by rotating the operation knob 72 in the clockwise direction and the counterclockwise direction.

When the positioning of the image frame is completed, the negative carrier 22 is positioned on the work table 14 of the printer processor 10. As a result, the desired image frame is positioned at the printing position, and the exposure process is completed by transmitting the light from the light source 17 and printing it on the printing paper 36.

When there are a plurality of images to be reprinted, the above work may be repeated. The photographic printing paper 36 reaches the processing section 42 through the reservoir section 40, is subjected to color development, bleach-fixing and rinsing processing, is then dried in the drying section 44, and is cut into individual images by the cutter section 46 and accumulated. It

Upon completion of a series of reprinting processes, the operator operates the operation knob 72 to operate the spool driver 7
The spool 62 is rotated through 0 in the negative film winding direction.

By this rotation, the negative film 24 is
Although the tape is gradually taken up by the cartridge 52, jamming may occur at the time of taking-up, especially when the accommodation portion is loosened. However, in this embodiment,
The roller 98 of the film retainer 94 curved in an arc shape is pressed against the outermost periphery of the negative film 24 in the axial direction of the reel 84 by the urging force of the spring, thereby giving a resistance to the rotation. Due to this resistance, back tension is applied to the negative film 24, and no slack occurs during winding of the negative film 24 into the cartridge 52, so that the winding operation can be performed smoothly and reliably.

When all the negative film 24 is wound up, the door driver 74 is operated to close the door 66, and the opening / closing lid 58 is opened.
Is opened and the cartridge 52 is taken out and returned to the customer together with the finished print.

According to this embodiment, the negative film 24 is
Negative film 2 in a so-called minilab, which processes each book
Negative film 2 with curl when handling 4
Since the desired image frame can be searched and positioned at the printing position by passing the narrow gap between the plate members 76 and 78 without freeing No. 4, the curled negative film 24 may be accidentally bent. It is possible to improve workability without performing. Further, since it is not necessary to remove the curling habit by another work, the number of work steps does not increase, and the work efficiency is good.

In this embodiment, the arc-shaped film retainer 94 is used as a means for applying back tension to the negative film 24, but a spiral spring or a torsion coil spring is used for the reel 84 in the winding direction with a weak force. You may urge.

Further, the belt 88 is used to transmit the rotational force to the reel 84, but a gear may be used. Also, both may be used in combination.

Further, in the present embodiment, the reel 84 is arranged in the accommodating portion 82, and the operation of the operation knob 72 is transmitted via the belt 88 to rotate the reel 84 and wind the negative film 24. However, the accommodation portion 84 may be a space having only a circular inner circumference. That is, it is also possible to naturally wind the negative film 24 in a spiral shape depending on the curl of the negative film 24 itself.

[0056]

As described above, the manual negative carrier according to the present invention can reliably position the photographic film having a curl tendency at the printing position during the manual work (manual handling) and maintains its flatness. It has an excellent effect of being able to.
