[Problem to be Solved by the Invention] However, since the space between the photographed frames is normally set to be extremely narrow, if you try to copy data within this narrow space, the data to be transferred will be The problem arises that users feel inconvenienced because the number must be reduced or the display area of each piece of data must be made smaller.

[0006] Furthermore, when data is to be imprinted in a narrow space, there arises a structural and cost problem in that a separate device from that for imprinting into the photographic frame is required.

[0007] In order to solve these problems, it is possible to set the distance between the photographic frames to be wide in advance, but if this is done, another problem arises in that the number of frames that can be photographed is reduced. This also works at a disadvantage for users.

Reference numeral 13 denotes photographic frame data imprinting means for imprinting photographic data D' different from the aforementioned photographic data D into each photographic frame P1 to Pn, which is provided separately from the duplex data imprinting means 6. ing.

In this case, the photographic frame data imprinting means 1
The installation position in the camera in step 3 is set at a position where, for example, the photographic data D' can be projected into a predetermined area from the back side of the film F with respect to the photographic frames P1 to Pn located in the exposure aperture. It is configured.

14 is this photographic frame data imprinting means 1
This is a selection switch for selecting use/non-use of item 3. Reference numeral 15 denotes a photographic data setting means provided in the camera or data imprinting device, which sets first data D1 and second data D2 to be imprinted on the front data photographing area A and the rear data photographing area B, and each photographic frame P1. ~Pn

Reference numeral 16 denotes display means or notification means for informing the user that all the frames that can be photographed have been exposed, and is configured to operate based on a coincidence signal from the unexposed frame presence/absence determining means 8 described above. ing.

Next, the operation or action of the data imprinting apparatus configured as described above will be explained with reference to the flowcharts shown in FIGS. 3 and 4. First, photographic data to be imprinted, such as data such as the date of the start of copying, is input or selected into the CPU 1 using the photographic data setting means 15.

In this case, the photographing data is the first data D1
, the second data D2, and another photographic data D' are input separately, but for example, only the second data D2 may be input later.

Next, as shown in FIG. 3, the cartridge 20 filled with, for example, 24-frame 135-inch film F is loaded into the camera (step S1; hereinafter, the description of "step" will be omitted), and the film F is loaded. After setting the leader part to the automatic winding (auto loading) position, close the camera back cover (S2).

[0042] In this way, this closing operation turns on the back cover switch 2 and outputs the on signal to the CPU 1, so the film DX reading means 3 reads the characteristic information of the film used and reads the information. The information is output to the CPU 1, and the CPU 1 starts predetermined photographing sequence control (S3).

Now, the CP that started the photographing sequence control
U1 first operates the film winding means 4 and controls the film F to be wound up. At this time, since the film movement amount detection means 5 detects the movement amount of the film F and outputs the detection result to the CPU 1, the CPU 1 can determine whether the number of perforations detected from the film movement amount detection means 5 and the number of preceding perforations N1 are different from each other. until it matches
That is, the film winding means 4 is operated until the front data photographing area A of the film faces the exposure opening (S4
).

[0044] Therefore, the leader part of the film F, which had already been exposed when loaded into the camera, is taken up by the take-up reel, and the following front data photographing area A (unexposed part) is positioned at the exposure opening. However, the determination as to whether this position has been reached is made by the film movement amount detecting means 5 as the front data photographing area setting means and the storage means and comparison means in the CPU 1 (S5).

When the film F stops at this exposure aperture (S6), a command is issued from the CPU 1 to the first data imprinting means 9 to perform imprinting. The first data imprinting execution unit 9 that receives the first data imprints the first data D1 into the front data imaging area A via the duplex data imprinting unit 6 (S7).
.

[0046] When this imprinting operation is completed, CPU1
Then, the film winding means 4 is operated again (S8),
After the film F is moved until the number of perforations detected by the film movement amount detection means 5 matches the number of intermediate perforations N2 stored in the CPU 1 (S9), the film winding operation is stopped (S10).

Thereafter, the film DX reading means 3 reads the film sensitivity value, the number of photographable frames, etc., and stores them in the memory circuit of the CPU 1 (S11).

At this stage, the first photographic frame P1 is positioned at the exposure aperture, so that the user can perform photographing operations for the first time.

In this case, the photographing operation is carried out in the same manner as the normal photographing operation (S12), but while each photographic frame is being photographed, the exposed frame number counting means 7 counts the number of photographed (exposed) frames. It counts and outputs the counting information to the CPU 1 each time, and the unexposed frame presence/absence determining means 8 compares this counting information with the stored number of frames that can be photographed and informs the CPU 1 of the presence or absence of unexposed frames. Since the output continues, the CPU 1 continues the photographing sequence control for the next photographic frame while confirming that unexposed frames remain.

That is, when the shutter release is performed for the photographic frame at that time, the CPU
1 operates the film winding means 4 to wind the film by the number of perforations N3 during photographing, and controls the unexposed photographic frame to be moved to the exposure opening.

As the photographing progresses in this manner, when all the exposures for, for example, 24 frames stored in the cartridge 20 are completed, at that point, the unexposed frame determination means 8 indicates the number of frames that can be photographed and the number of exposed frames. Since a coincidence signal with the number of frames is output, the CPU 1 confirms that there are no more unexposed frames based on this coincidence signal, and stops the film winding control from now on.
6 to notify the user that the shooting has ended.

Now, when the photographing is completed, the film F can be rewound using the manual rewind operation means 11, but in the illustrated embodiment, the coincidence signal of the unexposed frame presence/absence determination means 8 described above is It is also configured so that the film F can be automatically rewound using the .

The unexposed frame presence/absence determining means 8 outputs a coincidence signal between the number of photographable frames and the number of exposed frames, and then winds the film until the film end is detected. That is, as shown in the right-hand path (S13 to S15) in FIG. 4, on the film F following the final exposed frame P24,
The unexposed part (
It is determined whether there is a trailing perforation (equivalent to N4) (S15), and if there is an unexposed part on the remaining film F that can form the rear data shooting area B, it is determined whether or not there is a trailing perforation (corresponding to N4). The signal is output, and the flowchart branches to YES at S15 and proceeds to the process at S16.

Thereafter, the second data imprinting execution means 10 is operated to control the second data D2 to be imprinted in this rear data photographing area B.

When the operation of imprinting the second data D2 is completed (S16), the CPU 1 issues an operation command to the film rewinding means 12 to automatically rewind the wound film F into the cartridge 20. Control as follows.

As a result, the film F is rewound by the film rewinding means 12, and when the film F is completely rewound, the film rewinding operation is completed (S16 to S21).

Now, if it is desired to rewind the film F during the photographing operation (at a stage where there are still unexposed photographic frames), the manual rewind operation means 11 is used to operate the film F to rewind.

That is, manual rewind operation means 1
1 (S22), since there are still unexposed photographic frames remaining, the unexposed frame determination means 8 outputs a winding enable signal.

Therefore, the CPU 1 immediately operates the film winding means 4 (S23) until it is determined that the film F has been wound by the number of trailing perforations N4 (S24), that is, the rear data photographing area B is the double data. The film F is moved to a position facing the imprinting means 6, and the operation of the film winding means 4 is stopped.

Since the subsequent operation is the same as in the case of automatic rewinding described above, a detailed explanation thereof will be omitted to avoid complexity.

The operation of imprinting the first data D1 and the second data D2 by the duplex data imprinting means described so far is carried out regardless of whether or not the intra-frame data imprinting means 13, which will be described later, is activated or not. That will happen.

On the other hand, to imprint another photographic data D' by the photographic frame data imprinting means 13, press the selection switch 1.
It can be carried out arbitrarily by operating 4.

In this case, the other photographic data D' is as follows:
For example, it is preferable to select information such as the shooting date or date, hour, and minute, but the control at the time of imprinting is performed by the CPU 1 in the same manner as in the case of a conventional camera or data imprinting device. In synchronization with the release operation, each of the photographic frames P1 to P24 is imprinted.

By the way, the first data D1 in the illustrated embodiment
and how to use the second data D2 will be explained.

For example, the photographing date of the first photographed frame P1 (for example, January 1, 1988) is stored in the first data D1.
If the photographing date of the last photographed frame P24 (for example, January 7, 1988) is imprinted in the rear data photographing area B as second data D2, this film The shooting date of each scene shown in F can be recorded in the form of a shooting period.

Furthermore, at the stage of printing this film F, the first data D1 and the second data D2 are combined as shown in FIG. It is also possible to print on a print.

[0067] Also, the first data D1 is the photographing date (
For example, the second data D2 is imprinted in the front data photographing area A as 815), and the second data D2 is imprinted in the rear data photographing area B as the exposure order of the photographic frame (for example, 9). (e.g., 81
59) and can be printed onto individual prints.

As explained above, in the camera data imprinting device according to the present invention, necessary Capable of imprinting photographic data 1
The configuration is such that one or two data capturing areas are formed and desired capturing data can be imprinted into these data capturing areas before and/or after the image capturing operation.
To imprint clear data onto a film without having the drawback of reducing the number of frames that can be photographed by using a conventional data imprinting device having a configuration similar to that of a data imprinting device for photographing frames. Now I can do it.

Although one embodiment has been described above, the present invention is not limited to this, and can be modified in various ways without departing from the gist thereof.

For example, in the above-mentioned embodiment, an example was explained in which in-frame data imprinting means 13 was provided separately in addition to data imprinting means 6, but it is also possible to use these as a single unit. It is. In this case, the data imprinting means 6 will be arranged at the end of the exposure opening.

[0071]

Effects of the Invention As described above, when using the present invention, the unexposed area on the film located before the first frame, and/or the unexposed area on the film following the last frame. It becomes possible to realize a new camera data imprinting device that can imprint various data.
