Abstract

PURPOSE:To exactly make a photographing data correspond to a photographed film, by constituting the titled system so that a film identifying data being difference at every film is stored together with the photographing data by a storage means, and also, a data corresponding to the film identifying data is insert-photographed into the film by an insert-photographing means. CONSTITUTION:A nonvolatile memory 14 is controlled by a CPU 11 so as to store a photographing data at every photographing frame, and also, so as to store the total number of photographed pieces of a film, as a film identifying data being different at every film to be photographed. The photographing data and the total number of photographed pieces of the film which are stored in the nonvolatile memory 14 are read to a CPU 21 side through the CPU 11 and a connecting means 30. Also, the total number of photographed pieces of the film, which is read to the CPU 21 side is insert-photographed into the last frame of a no-load feed by an insert-photographing means 24. In such a way, the photographing data which is stored can be made exactly to correspond to a photographed film.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a camera system that stores photographic data for each photographed frame.

(Prior Art) Various camera systems have been proposed in the past that store photographic data such as photographing date, shutter speed, aperture value, etc. for each photographed frame.

(Problem to be solved by the invention) However, in such a conventional camera system,
When displaying or printing the stored data after completing shooting for multiple films by storing the shooting data frame by frame, the displayed or printed shooting data and the film that has already been shot may be different. There is a problem in that it becomes impossible to determine which film the photographic data belongs to, and the purpose of storing the photographic data frame by frame becomes meaningless.

The present invention has been made in view of these conventional problems, and it is an object of the present invention to provide a camera system that can reliably associate stored photographic data with photographed film.

(Means for Solving the Problems) The gist of the present invention to achieve the above object is to store photographic data for each photographed frame in a camera system (camera body 10 + data bag 20) that stores photographic data for each photographed frame. and a storage means (non-volatile memory 14) for storing different film identification data for each film to be photographed, and an imprinting means 24 for imprinting data corresponding to the film identification data on the film. The camera system is characterized by:

(Function) In the camera system described above, the storage means (nonvolatile memory 14) stores photographic data for each photographed frame and film identification data that differs for each film to be photographed, and the imprinting means 24 stores the photographic data for each photographed frame, and the imprinting means 24 stores Data corresponding to the identification data is imprinted onto the film. Therefore, it is possible to reliably associate the stored photographic data with the photographed film.

(Example) An embodiment of the present invention will be described below based on one drawing.

1 to 5 show an embodiment of the present invention.

As shown in FIG. 1, a camera system is comprised of a camera body 10 and a data bag 20 attached to the camera body 10.

The camera body 10 includes a CPU II that performs various calculations, controls, etc., a program memory 12 of the CPU II, a data memory 13, a non-volatile memory 14 as a storage means for storing photographic data, etc., and a shutter speed, film, etc. A photographing information setting section 15 for setting photographing data such as sensitivity is provided.

The data pack 20 includes a CPU 21 and a display 22.
, a keyboard 23 , and imprinting means 24 are provided, and information is transmitted between the CPU 21 and the CPU 11 via a connecting means 30 .

The non-volatile memory 14 can be controlled by the CPU 11 to store the photographic data for each photographed frame and to store the total number of films to be photographed as film identification data that differs for each film to be photographed.

The shooting data stored in the non-volatile memory 14 and the total number of shots of film are stored in the CPU II and the connecting means 3.
0 to the CPU 21 side.

The photographic data read into the CPU 21 and the total number of films taken can be displayed externally on the display 22 and printed out using a printer (not shown).

Furthermore, the cumulative number of shots of the film read into the CPU 21 II is configured to be imprinted by the imprinting means 24 on the last frame of the blank feed.

Next, an example in which the non-volatile memory 14 stores shooting data, etc. for three films will be explained based on FIG. Here, FIG. 2 shows the internal state of the nonvolatile memory 14.

As shown in FIG. 2, in each memory area of the non-volatile memory 14, addresses 0000 to 0001 contain the cumulative number of shots of the film currently being shot (the third grain film), 123, in hexadecimal. Quantity code QO7B
[Hereinafter, the hexadecimal representation is indicated by ()I). ], but addresses 0002 to 0003 store a cumulative number of shots code 0079 (H) indicating the cumulative number of films shot for the first film, 121, and address 0
After 004, actual photographic data for the first film is stored in order for each photographed frame (not shown).

Similarly, addresses 0101 to 0102 store the cumulative number of shots code 007A(H) indicating the cumulative number of shots of the second film, 122, and addresses 0103 and later store the actual number of shots for the second film. Photography data is stored in sequence for each photographic hump (not shown).

Similarly, addresses 0201 to 0202 store a cumulative number of shots code 007B()I) indicating the cumulative number of shots of the third film currently being shot, 123, and addresses 0203 and later store the number of shots for the third film. The actual photographic data for each photographed frame is stored in sequence.

Next, based on FIG. 3, a description will be given of how the total number of shots of the film stored in the nonvolatile memory 14 is imprinted onto the film. Here, FIG. 3 shows the third film.

Cumulative number of shots code 0 indicating the cumulative number of shots of the third film stored at addresses 0201-0202, 123
07B(H) is read into the CPU 21 side via the CPU II and the connection means 30 and is displayed as a decimal number 00.
Converted to 0123, total number of film shots 0001
23 is imprinted by the imprinting means 24 on the last frame (S frame) of the blank feed.

As shown in the figure, the shooting up to the second frame of this third film has been completed, and the date is imprinted on the first and second frames as shooting data by the imprinting means 2.
It is imprinted by 4.

Next, based on FIG. 4, a case will be described in which the photographic data of the third film stored in the nonvolatile memory 14 is printed out by a printer (not shown).

As shown in FIG. 4, as the photographic data printed out by the printer, the first line contains the letters FILMNO and the numbers 00012, which indicate the cumulative number of film shots.
3 is printed. On the second line, the number l indicating the first frame, the year, month, date, 9 hours, minutes, seconds, shutter speed, aperture value, and photographing data of the photographing mode are printed. Similarly, on the third line, the number 2 indicating the second frame and the same photographic data as the first frame are printed.

Further, the photographing data of the film can be displayed externally on the display 22 without being printed out.

Next, as shown in FIG. 3, the total number of film shots (here 0001
23) on the last frame (S frame) of the blank feed will be explained using the flowchart shown in FIG.

As shown in FIG. 5, when the film is loaded into the camera body 10 (#1), the film starts to be fed (#1).
2) A non-illustrated non-illustrated non-feeding position detection means determines whether the film has been pre-feeded to the last frame (S frame), that is, the frame before the first frame (#3), and the film is If the frame is skipped to the Sth frame, the presence or absence of film is checked by a film presence/absence detecting means (not shown) (#4), and if there is film, the cumulative number of shots of film is incremented by 1. 5
), the incremented cumulative number of shots on the film is imprinted by the imprinting means 24 (#6), and the film is further skipped forwarded by one frame (#7), and the film nozzle feeding operation is completed (#8). ).

It should be noted that in the case of a camera configured so that the film does not advance if no film is loaded, the above-mentioned film presence/absence detecting means (not shown) is not necessary.

Furthermore, it goes without saying that the film identification data is not limited to the total number of shots of the film, but may also be, for example, hour, minute, and second data at the time of blank feed, or data that can be manually set.

According to the above embodiment, since the film identification data, which is different for each film to be shot, is used as the cumulative number of films shot, it is possible to always know the cumulative number of films shot by the camera being used. It is extremely convenient as it allows you to easily know when to perform periodic inspections, etc.

Further, in the above embodiment, the cumulative number of shots of the film as film identification data is imprinted on the last frame (S frame) of the blank feed.

The present invention is not limited to this, but for example, if there is a concern as to whether or not the cumulative number of shots of the film will be reliably imprinted on the last frame (S frame) of a blank feed, then It is also possible to imprint the cumulative number of shots of the film on the frame located in the frame, advance one frame further, and then stop the blank feed.

In addition, the film identification data imprinted on the film is
It is sufficient that the film identification data is different from the film identification data imprinted on other films and corresponds to that stored in the non-volatile memory 14, and the data is stored in the non-volatile memory 14 as in the above embodiment. There is no need to imprint the same thing.

(Effects of the Invention) According to the camera system according to the present invention, different film identification data for each film to be shot is stored in the storage means together with shooting data for each shot frame, and data corresponding to the film identification data is stored in the storage means. is configured to be imprinted on the film by the imprinting means, so even if the stored data is displayed or printed after shooting with multiple films, the displayed or printed shooting data and the shot data are This is extremely convenient in practice.
