Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film viewer for confirming image frames when reprinting a photograph from a developed film in a cartridge.

[0002]

2. Description of the Related Art A film viewer is used to confirm each image frame, frame number, etc., when reprinting and reprinting a photograph. A conventional film viewer has, for example, 13
When targeting 5 types of film, the film cut into frames of 6 frames or less is stored in a multi-stage film storage sheet, so that the film storage sheet total width x the total area for the required number of stages can be uniformly irradiated. It has a viewer section.

An operator is printed directly on the designated image frame and the longitudinal edge of the film with or without such a film viewer 1, 1.
The frame numbers such as A, 2, 2A are visually confirmed. or,
In the case of the 135 type film, a check label is attached to each of the film and the storage bag for the visible image at the time of receiving a reorder for reprinting, so that the collation at the time of shipping is performed.

[0004]

By the way, in the case of checking each image frame by irradiating with the film of each stage in the film storage sheet in the above-mentioned film viewer, as described above, the operator specifies the additional printing. Image frame and frame No. Is visually confirmed, but at this time, the image frame and the frame number. Does not always correspond exactly, and, for example, there is a gap between the image frames and the frame number. May be burned. When setting the film of the camera, the frame No. This is because there is a possibility that it will shift.

Further, in the film stored in a plurality of stages on the film storage sheet, all frame numbers are not always inserted in order, and the numbers may be scattered or turned upside down. Therefore, even if the films in each stage are correctly inserted in order, the designated frame number. Since it is not known which image frame corresponds to which frame, the number of frames of the image is visually calculated from the beginning of the film after re-inserting in order, and which frame number is designated. It is necessary to confirm that it belongs to

For this reason, the conventional film viewer is capable of uniformly irradiating the entire area of the film storage sheet with the required width.

However, a film viewer of the type that irradiates the entire area of such a film storage sheet has a large overall structure, and since the entire area of the sheet is large, the light source for irradiation must be strong.

On the other hand, the developed film in a cartridge is a film of a type in which one film including the total number of image frames that can be photographed is not cut, but directly developed and wound into a cartridge for storage. At the time of printing the frame, the film is fed out, and after the exposure process for printing, the film is rewound into the cartridge and is handed to the customer as it is together with the printed photograph.

When reprinting from such a type of film by reordering, it is necessary to pull out one film from the cartridge to confirm the designated image frame, but since this film is viewed with a conventional film viewer. However, it is not possible to cut the film into appropriate frames.

Further, the designated image frame and frame number. To see if they match, change the orientation of the film or There is no need to check whether the frames are in order, and since the film frames are continuous, the frame number from the beginning of the film. Is relatively easy to count.

Therefore, it is not appropriate to confirm the developed film in a cartridge with a conventional film viewer, and a dedicated film viewer for the cartridge housing film has been desired.

The present invention is for exclusive use with a cartridge storage film, in which various problems that cannot be processed by the conventional film viewer as described above are noted, and the cartridge storage film can be sent by the transport unit and visually confirmed for each frame in the viewer unit.
