Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera in which a patrone containing a roll film is loaded and a photographing range on the image receiving surface of the roll film can be arbitrarily selected and set by an external operation.

[0002]

2. Description of the Related Art In recent years, a conventional 35 mm photographic roll film and a 35 mm full size camera are used, and a frame attachment is attached so that the photographing range (aperture) on the image receiving surface can be changed to a normal full size (24 × 36 mm). ) To panorama size (13 × 36 mm) to form a panorama photo is available in both sizes. The cameras for both sizes can select the shooting range only when the film is loaded, and cannot select the shooting range after loading the film.

Also, a camera dedicated to the panoramic size has been released.

More recently, a dual-purpose camera has been announced in which, even after the film is loaded, the photographing range switching selection can be appropriately operated from outside the camera body.

[0005]

When taking a picture with the above-mentioned camera, it is not possible to see the undeveloped patrone that has been taken.
It is unclear whether the size in the film, that is, the full size is a panoramic size or a mixture of both sizes. When a patrone of such unknown content is requested to a minilab contractor who can only print in full size (service size print), it is known that it is in panoramic size after film development. Therefore, there is a problem that the print distribution route must be changed after development.

In particular, a dual-purpose camera capable of selectively switching between full size and panoramic size after the film cartridge of the camera is loaded is widespread. Since it will be distributed to the traders, it is expected that changes in the process after development will cause confusion in the operation of the photo lab, such as print prices and print delivery deadlines.

[0007]

When the cartridge is loaded at a predetermined position in the cartridge storage chamber 15, the recording head 17 and the heat-sensitive recording material 24 provided on the outer peripheral surface of the cylindrical body 21 of the cartridge 20 are arranged to face each other. Then, the thermal head 17 moves to come into surface contact with the thermosensitive recording material 24 by the input of the imaging range setting information by the imaging range changeover switch 6, and the plurality of heating elements arranged in a matrix are heated to the thermal recording material 24. A predetermined identification symbol for each shooting size is displayed and recorded.

FIG. 5 is a diagram showing identification displays corresponding to the various shooting sizes and mixed frame sizes thereof. The identification display D1 shows the first embodiment, and ... It is an example (1, 4, 7), and
Is a mixed frame display example and is a print example (H, n, 9, A) when the photographer sets a size different from the first frame by using the changeover switch 6. However, the printing is performed only after the first frame is shot after the setting is changed, and if the same combination is subsequently shot, the printing is not performed.

The printing process by the thermal head 17 is carried out by the process shown in the flow chart of FIG. 6 in the external size switchable camera for full size, panorama size and other sizes.

(1) The cartridge storage chamber 15 of the camera body 1
When the cartridge 20 provided with the photographing range information recording unit 24 is loaded into the camera and the main switch 2 of the camera body 1 is turned on,
The presence or absence of the Patrone 20 is confirmed.

(2) When the presence of the cartridge 20 is confirmed, the DX code printed on the cylinder 21 of the cartridge 20 is connected to the DX contact 16 of the camera body 1, and the ISO sensitivity and the number of frames that can be filmed are recorded. Confirmation is done.

(3) Next, it is displayed on the display panel 4 so as to specify the photographing size (negative size) and prompts the photographer to set the size. The photographer sequentially presses the photographing range selector switch 6 to select a desired photographing size from 35 mm full size (F), panoramic size (P) and other sizes (T). At this time, if the photographer performs a photographing operation without pressing the photographing range changeover switch 6, the camera side determines that the size is 35 mm full size (F), and performs photographing. Here, the designation of the 35 mm full size (F), the panorama size (P), and other sizes for the first frame is displayed on the display panel 4, and the photographing mechanism in the camera body 1 is switched. When the shooting size is selected, the camera body 1 confirms the shooting size and is ready to shoot.

(4) When the photographer presses the shutter release button 5 and photographs the first frame, the camera body 1 confirms whether or not the film has been wound up, and then confirms the number of photographed frames. As a result, the thermal head in the camera body 1
The numeral 17 prints "1" shown in FIG. 5 on the thermosensitive recording material 24 provided on the cylindrical body 21 of the cartridge 20.

(5) When the photographer specifies a panoramic size (P) photographing range, the light-shielding plates 14A and 14B shield a part of the aperture (aperture) 11 of the camera body 1 from light, thereby exposing the film photosensitive surface. The shooting range is regulated, and the shooting range is displayed on the display panel 4 to enable shooting.
When the shutter release button 5 is subsequently pressed to take a picture, the thermal head 17 prints "4" on the thermal recording material 24.

(6) For other sizes (T), for example, in the trimming designation mode, "7" is printed on the thermosensitive recording material 24 in the same manner. These print contents are from the identification display D1 of FIG. 5 to other prints, for example, the identification display D2 of FIG.

(7) In the second and subsequent frames, when the photographer sets a size different from that of the first frame and shoots, the prints shown in (1) to (5) of FIG. 5 are performed.
That is, is printed in the same printing position as the printing of the first frame over. However, these prints are performed only after the first frame is photographed after the setting change, and thereafter, when the same combination is photographed, the printing is not performed.

(8) By repeating the size setting operation and photographing, the photographer can photograph up to the last frame of the film. After that, the photographer takes out the photographed film from the camera body 1 and brings it to a laboratory agency store or a minilab installation store for a print request.

(9) The print contractor confirms the symbol (identification display D1 or D2 in FIG. 5) printed on the recording portion (heat-sensitive recording material) on the cartridge, and confirms various film sizes such as film frame size. Check the presence of mixed sizes and present the date and time of print finish to the client (customer).
get an agreement.

(10) In the printing operation, the type and the mixture of the photographed sizes are confirmed, and the negative film is distributed to the print production line by arranging the processes separately. After that, depending on the selected print production line,
It becomes possible to quickly and surely perform film development processing, printing paper printing processing, and the like.

The above is one embodiment of the present invention.
Similar printing can be performed by providing a means other than the heat-sensitive recording as the means for recording the identification symbol, for example, a multi-wire head on the camera body side and a pressure-sensitive recording material on the cartridge side.

Further, as an example of the identification symbol, the pattern other than D1 and D2 may be printed.

Further, in the above-mentioned embodiment, the camera having the zoom mechanism or the bifocal mechanism is designated, but other monofocal cameras, single-lens reflex cameras, etc. can be implemented with the same mechanism as the above-mentioned embodiment. It is possible to identify and print.
