Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a negative carrier for a photographic printer which positions a negative film when an image on the negative film is printed on a photosensitive material by exposure. For example, a photographic printer or a combination of a photographic printer and a processor. It is used for printer processors.

[0002]

2. Description of the Related Art A printer processor is called a minilab and is installed in a DPE store or the like. This printer processor has a printer unit that prints and exposes an image recorded on a negative film onto photographic paper, and a processor unit that develops the photographic paper that has been subjected to the print-exposure process. The printer can be automatically conveyed and processed in the printer unit and the processor unit only by setting the printer in the printer processor. In the printer section of this printer processor, the image on the negative film is enlarged to a predetermined size selected and printed on the photographic paper, and the photographic paper on which the image is printed is sequentially conveyed to the processor section. Developed and finished as a photographic print.

Further, in recent years, photographic prints such as panorama size, which has a horizontal length twice as large as a normal size photographic print, have become popular in addition to the full size. Frames with screen sizes different in aspect ratio from full-size frames are now mixed in one negative film together with full-size frames.

On the other hand, when the image on the negative film is printed on the printing paper, from the viewpoint of operability, a negative carrier for positioning the negative film on the work table of the printer processor is fixed in a fixed direction from the viewpoint of operability. That is, the negative exposure film was conveyed only along the transverse feed direction, and the exposure processing was performed.

However, as a result of the existence of plural kinds of image frame sizes in the negative film as described above,
Not only is it necessary to carry out the printing exposure processing while conveying the negative film in the negative carrier only along a certain direction, it becomes necessary to convey the negative film along the longitudinal feeding direction which is a direction intersecting with this direction. It was

That is, when a panoramic size photographic print is printed by exposure, the horizontal length of the photographic print is twice as long as the normal size full-size photographic print, but the vertical length is full-size. Since it is the same as the photographic print, it was considered that the width dimension of the long photographic printing paper should be matched with the length of the photographic printing in the vertical direction to reduce the number of troublesome photographic printing paper replacement work.

[0007]

However, in this case, when the negative film is fed to the negative carrier in the same manner as the lateral feeding as well as the longitudinal feeding, the light source device installed on the work table of the printer processor to irradiate the light rays passing through the negative film. Side, the negative film that has undergone the baking exposure process is sent out,
There is a drawback that it becomes difficult for an operator to handle the negative film that has been subjected to the baking exposure treatment.

In view of the above facts, an object of the present invention is to obtain a negative carrier for a photographic printer, which makes it easy to handle a negative film which has been subjected to printing exposure processing.

After the completion of all printing exposure processing,
The drive source is reversed to convey the negative film in a direction opposite to the original conveying direction of the negative film, and the sensor detects the starting end side of the negative film in the conveying direction. Then, in a state where the starting end side in the carrying direction is sandwiched by the roller pair, the operation of the drive source controlled by the controller based on the signal from the sensor stops, and the carrying by the roller pair is stopped.

Therefore, the negative film which has been subjected to the printing exposure process is stopped in a state of returning to the introduction end side of the transport path.

For example, if the discharge side roller pair is arranged below the introduction side roller pair, the negative film once completely sent out from the introduction side roller pair along the conveyance path is
Since the negative film is moved downward by its own weight, when the negative film is conveyed in the direction opposite to the original conveying direction due to the reverse rotation of the driving source, it is fed to the discharge side roller pair side below the introduction side roller pair.

Therefore, similarly to the first aspect, the negative film which has undergone the printing exposure process is stopped in a state of returning to the introduction end side of the transport path. Therefore, even if the installation direction of the negative carrier with respect to the photographic printer is changed, the operator can easily remove the negative film that has undergone the printing exposure process from the negative carrier, and the handling of the negative film is easy. Moreover, since the next negative film can be loaded on the introduction-side roller pair before the negative film is removed from the negative carrier, the processing efficiency can be further improved.

The operation of the negative carrier for the photographic printer according to claim 3 will be described below. The upstream roller pair and the downstream roller pair driven and rotated by the drive source convey the negative film while sandwiching it, and stop and position the negative film at the exposure position during printing exposure.

Further, when the direction different from the direction toward the light source device is set as the transport direction of the negative film, the sensor detects the end side of the transport direction of the negative film after all printing exposure processing is completed.

And, as shown in FIG. 7, the first end NS side in the transport direction is the first side.
The motor 152 is rotated by a predetermined amount so as to be sandwiched by the roller pair 162, and in this state, the operation of the motor 152 controlled by the controller 182 based on the signal from the screen detection sensor 176 is stopped, and the first roller The conveyance by the pair 162 is stopped.

Therefore, in the case of vertical feeding, the negative film N for which the exposure process for printing has been completed is the negative film passing portion 3
It will stop in the state of returning to the 0A introduction end 30C side. Therefore, the printer processor 1 of the negative carrier 30
Regardless of whether the installation direction with respect to 0 is vertical or horizontal, an operator standing on the left side of the printer processor 10 in FIG. 1 can easily remove the negative film N for which the exposure process has been completed from the negative carrier 30. This makes it possible to handle the negative film N easily.

On the other hand, in the case of vertical feeding, since the negative film N is conveyed along the conveying direction of the photographic printing paper P, as shown in FIG. 12, from the full size image frame N1 to the panoramic size Even if the type of the image frame on the negative film N is changed to the image frame N2, it is possible to change the enlargement ratio of the printing exposure to 89 × 1 without changing the photographic paper P.
89 x 254 from the 27 mm full size print size
The print size can be changed to a panoramic size of mm, and the image on the negative film N can be easily printed and exposed on the photographic paper P located at the image printing position in the printer processor 10. It should be noted that the opening amount of the mask piece is naturally adjusted by the variable mask mechanism during this change.

A negative carrier of a second embodiment of the negative carrier for a photographic printer according to the present invention is shown in FIG. 13, and this embodiment will be described based on this drawing. The same members as those described in the first embodiment are designated by the same reference numerals, and the duplicate description will be omitted.

As shown in FIG. 13, an introducing roller pair 192 formed in the same manner as the roller pair of the first embodiment is arranged on the introducing end 30C side of the negative carrier 30, and an introducing roller pair 192 is arranged. At the lower side of the discharge side roller pair 194
Is arranged. Then, the introduction side roller pair 19
2 and the discharge side roller pair 194 are connected to each other so that rotation is transmitted from a motor, which is a drive source (not shown). The motor is connected to the controller 182.

Therefore, also in this embodiment, when the operator inserts the negative film N into the introduction side roller pair 192 as the vertical feed and presses the start key as in the first embodiment, the printing paper P is printed and exposed. . After the printing exposure processing of all the image frames is completed, the motor 152 is rotated in the reverse direction so that the roller pair 162, 164, 166, 168 conveys the negative film N in the direction opposite to the original conveying direction of the negative film N. To do.

At this time, the negative film N once sent out completely from the introduction side roller pair 192 along the negative film passing portion 30A moves downward due to its own weight, so that the negative film N is initially moved by the reverse rotation of the motor. When it is conveyed in the opposite direction to the conveying direction, it is sent to the discharge side roller pair 194 side below the introduction side roller pair 192.

Along with this, the screen detection sensor 176 detects the start side NS side of the negative film N in the transport direction. Then, as indicated by a broken line in FIG.
The conveyance by the discharge side roller pair 194 is stopped in a state where the side is sandwiched by the discharge side roller pair 194.

Therefore, as in the first embodiment, the negative film N for which the printing and exposure processing has been completed is stopped in a state where it has returned to the introduction end 30C side, and the operator can easily finish the negative film N for which the printing and exposure processing has been completed. The film N can be detached from the negative carrier 30, and the negative film N can be easily handled. Further, with the configuration of this embodiment, the next negative film N can be loaded on the introduction side roller pair 192 before the negative film N is removed from the negative carrier 30.
The efficiency of the processing can be further improved.

In this embodiment, the introduction side roller pair 1
Although the discharge side roller pair 194 is arranged at the lower position of 92, the reverse order may be adopted. In this case, the negative film passing portion 3
It is conceivable to dispose a switching piece or the like for path switching on 0A to forcibly guide the negative film N to the discharge side roller pair 194 side.

Further, in the first and second embodiments, the screen detection sensor 176 is used to start the negative direction N of the negative film N in the transport direction.
Although S or the like is detected, it may be detected by another sensor. Further, the controller is the controller 182, but specifically, a device such as a computer can be used.

On the other hand, in the above embodiment, the negative film N has been described on the assumption that there are two types of image frames having different aspect ratios, full size and panoramic size, but three or more types of image frames having different aspect ratios. It is needless to say that the present invention can be applied even if there exists.
