Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing information recording device used for a camera, and more particularly to a photographing information recording device for a camera which records the photographing information of each photographing frame on a preliminarily secured collective copying frame.

[0002]

2. Description of the Related Art The applicant of the present application secures a frame for imprinting photographing information at a predetermined position on a film in advance in order to provide photographing data to a user at the time of photographing, and when all photographing is completed. There is proposed a photographing information imprinting device for a camera, which starts rewinding and stops rewinding at a secured frame position so that the photographed information of the photographed frames stored at the time of photographing can be imprinted together (Japanese Patent Laid-Open No. 8- 160524
issue).

This photographing information imprinting apparatus for a camera not only imprints a number of lines corresponding to the number of photographed frames on a group of photographed frames, but also records the start date of photographing on the top line of the grouped photographed frames so that the user can organize photos. At the same time, the shooting end date can be collectively copied and imprinted on the last line.

Further, the number of lines to be imprinted on the collective copy frame can be defined in advance. At this time, the number of lines extra than the actual number of frames to be photographed is taken into consideration in consideration of the variation in the number of recordable images until the film is stretched. It is necessary to secure it. As a result, it is conceivable that dummy lines such as "---" will be imprinted as lines that have no image data in the actually imprinted lines. In particular, when the user rewinds midway, there are a plurality of lines with no shooting data.

[0005]

However, in the case where the number of lines to be collectively copied is defined in advance in this way, when the film feed amount of one line is changed due to factors such as battery removal and attachment in the middle, When an overrun occurs, the shooting end date, which is the last line of the batch copy frame, is not printed, which is inconvenient for organizing photos.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a photographing information imprinting device for a camera in which the photographing end date is always imprinted on the last line of the collective copying frame.

[0007]

In order to achieve the above object, in the present invention, storage means for storing shooting information and shooting start date and time and shooting end date and time regarding a frame to be shot, and shooting information stored in the storage means and An imprinting means for imprinting the shooting start date and the shooting end date on the film and a predetermined frame of the film are secured in advance, and the end of the predetermined frame is placed at the imprinting part of the imprinting means at the beginning of the photographing start. The photographing end date is positioned on the last line in the line, the photographing information is imprinted after the film is sent line by line, and a plurality of predetermined line units are imprinted on the collective photo frame. In the shooting information imprinting device,
When the film feed amount for each line is detected, an addition unit for sequentially adding the film feed amount by the detection unit with the film feed for each line, and when the addition amount by the addition unit exceeds a specified value, There is provided a photographing information imprinting device for a camera, comprising a control means for imprinting the photographing end date with priority.

Further, in the above-mentioned camera photographing information imprinting device, when a frame having no photographing information occurs in the middle, dummy data imprinting means is imprinted so that dummy data is imprinted so that a predetermined number of unit lines are obtained at the time of collective copying. The control means for imprinting the photographing end date preferentially provides the photographing information imprinting device for a camera for imprinting the photographing end date only on the imprinting area by the dummy data imprinting means.

According to the above construction, when the film feed amount for one line is changed due to the attachment / detachment of the battery, the film feed overrun or the film feed error occurs, or the film is rewound midway. Even if a piece for which shooting information is not generated occurs due to factors such as the above, the shooting end date is always printed on the last line of the collective copying piece.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external view showing an embodiment of a photographing information imprinting apparatus for a camera according to the present invention,
(A) is a front view and (b) is a sectional view. FIG. 2 is a circuit block diagram of a photographing information imprinting apparatus for a camera according to the present invention.

In the figure, the camera body includes a control unit 14,
It has a photographing information storage unit 13, a film drive unit 17, a film position detection unit 18, and a film feed amount detection means 19. The imprinting device 1 integrally provided on the back cover of the camera includes an imprinting control unit 15, an imprinting unit 16, an imprinting data display unit 3, and operation buttons 2. Here, the imprinting section 16 is composed of the light source 5, the lens 6, the mirror 7, the liquid crystal display section 8, the mask plate 10 and the like shown in FIG.

The control unit 14 controls the photographing operation of the camera, and the photographing information storage unit stores an exposure correction value, a shutter speed, an aperture value, a photographing mode, a photographing start date, a photographing end date, etc. every time one frame is photographed. Store in 13. Further, when the collective copy is selected by the collective copy selection button 2g of the operation button 2, the film driving unit 17 is driven to perform the film feed control so that the photographing information is imprinted. The film position detection unit 18 detects the frame on which the photographing information is imprinted by detecting the position of each frame. The film feed amount detection means 19 detects the film feed amount in the film drive unit 17, and the detection pulse is sent to the control unit 14.

When the control signal relating to the imprinting and the photographing information read out from the photographing information storage unit 13 are sent from the imprinting control unit 15, the imprinting control unit 15 displays the photographing information on the liquid crystal display unit 8 to turn on the illumination system. It is turned on to control the photographing information to be photographed at a predetermined position on the frame. At the same time, the photographing information is also displayed on the imprint data display unit 3.

FIG. 3 is a flow chart for explaining the operation of the camera photographing information recording apparatus according to the present invention.

The control unit 14 detects the opening and closing of the back cover by a detection unit (not shown) (S401), and when it detects that the back cover is closed, it determines whether or not a film is loaded (S402). If no film is loaded, the control operation ends. When the film is loaded, the DX code of the film is read to detect the number of shots (S403).

Next, it is determined whether or not the collective copy of the shooting information is selected (S404). If collective shooting of shooting information is not selected, normal jump feed control is performed (S405). If collective shooting of shooting information is selected, blank feed for collective copy frames is not performed in addition to normal blank feed. (S406).

The control unit 14 stores the photographing data of the frame each time it is photographed (S407, S408). Further, the control unit 14 detects and determines whether or not it is a film end by a detection unit (not shown) (S409).

If it is the film end, the film drive unit 17 is driven in the reverse direction to start rewinding the film (S410). And the film position detection unit 18
The frame position is detected by, the rewinding operation is braked, and the head of the collective copy frame is stopped at the position of the copy section 16 (S411).

Next, the control unit 14 reads the shooting start date from the storage unit 13 (S412) and sends the shooting start date to the imprinting control unit 15. The imprinting control unit 15 displays the shooting start date on the liquid crystal display unit 8 and turns on the light source 5 to print the shooting start date on the film (S413). Then, when one line is printed, the information is transmitted to the control unit 14, and the control unit 14 sends the film for one line. At this time, the control unit 14 receives the film feed amount from the film feed amount detection unit 19.

Subsequently, similarly, the imprinting control unit 15 receives the imprinting data from the control unit 14, and the liquid crystal display unit 8
After that, the control unit 14 feeds the film for one line. The detected film feed amount at this time is added to the previous film feed amount.

While batch copying is continued in this way, the control unit 14 determines whether or not the specified number of lines have been imprinted (S414), and if the specified number of lines has been imprinted, the final line is imaged. After imprinting the end date, end the batch copy. On the other hand, the control unit 14 determines whether the added film feed amount after the film feed is larger than the specified amount that exceeds the collective copy area (S415). After imprinting, the batch copying is finished.

After the completion of the collective copying, rewinding is started (S416), and when the film is completely rewound, the rewinding operation is finished (S417).

FIG. 4 shows an example of the present invention in which photographing information is imprinted on a 12-film film, where (a) is the basic format, (b) when the photographing end date is not imprinted, (c). The case where the shooting end date is imprinted is shown. FIG. 4A shows an example of a collective copy using the present system, showing a case of shooting with a 12-shot film, and 25 lines are copied onto one frame of the collective copy. The first line of the summary is the shooting start date, and the last line is the shooting end date. FIG. 4B shows an example in which the last line cannot be printed due to a film feed error when the control of the present invention is not performed. FIG. 4C shows an example in which the shooting end date is imprinted even if a film feeding error occurs due to the control of the present invention.

[0024]

As described above, according to the present invention, a film feed error occurs when the film feed amount of one line is changed due to a battery removal or the like during the process, or when a film feed overrun occurs. Even in the case, the shooting end date, which is the last line of the collective copy frame, is imprinted, and the inconvenience when the user organizes the pictures is eliminated.
