In the camera of this embodiment, the viewfinder field ratio, which is the ratio of the viewfinder screen to the screen actually seen on the film surface, is not 100% but 90%, for example. That is, as shown below, the camera has a viewfinder field smaller than the screen projected on the film surface.

This operation is started from step 202 through step 202 when the switch SW1 which is turned on by the first stroke of the release button (not shown) is turned on. [Step 202] Photometry is performed using the photometry circuit 7.
In addition, the microcomputer 1 determines the Tv value based on the photometric data according to the mode set in the camera.
The Av value is calculated. [Step 203] The focus detection circuit 6 is used to measure the distance to the subject, and the microcomputer 1 communicates the lens drive amount to the lens control circuit 2 based on the measured distance data to perform focus drive. [Step 204] Here, the release switch SW2
When is turned on, it is determined whether or not the release is permitted. For example, if the camera cannot be released when the mode is out of focus, the release is not permitted until the distance measurement result shows that the focus is in focus. Repeat the operation of. on the other hand,
If the subject is in focus, the release may be permitted, and the process proceeds to step 205. [Step 205] Here, the state of the release switch SW2 that is turned on by the second stroke of the release button is checked, and if it is off, the process returns to step 202 and the same operation is repeated. If it is turned on, the process proceeds to step 206 to perform the release operation. [Step 206] The quick return mirror is moved up, and the Av value determined in step 202 is communicated to the lens control circuit 2 to narrow it down. [Step 207] The data to be imprinted on the film is communicated to the data imprinting circuit 11, and the LED segment group 12
Control the lighting of.

Here, the lighting time of the LED segment group 12 varies depending on the ISO sensitivity of the loaded film, and the data printing end time varies depending on the ISO sensitivity. [Step 208] The front curtain of the shutter is started via the shutter control circuit 8 and the shutter front / back curtain actuator 13. [Step 209] T calculated in the above step 202
After a time period corresponding to the v value, the rear curtain of the shutter is started via the shutter control circuit 8 and the shutter front / rear curtain actuator 13.

As a result, the exposure operation for the predetermined frame of the film is completed. [Step 210] After the shutter travels, the quick return mirror is moved down and the shutter is charged, and the lens control circuit 2 is communicated with to return the aperture of the lens to the open state. [Step 211] It is checked whether or not the lighting of the LED segment group 12 for data imprinting started in step 207 is finished. Here, if the LED segment group 12 is not lit for a time suitable for the ISO sensitivity of the film, wait until it is finished here, or if the lighting is finished, that is, if the data such as the shooting date is taken. If the imprinting has been completed, the process proceeds to step 212. [Step 212] Here, one frame of the photographed film is fed. Then, the process returns to step 202.

Next, the position of the data printed on the film surface as described above will be described with reference to FIG.

In FIG. 3, reference numeral 301 designates the range of the image projected on the film, which is determined by the size of the screen frame limited by the aperture opening between the shutter and the film. Reference numeral 302 denotes the range of the screen that can be seen by the finder.

As described above, in the camera of this embodiment, the viewfinder field ratio is not 100% but 90%, for example.
, Etc., which have a viewfinder field smaller than the image projected on the film surface.

The following 303 to 311 are segments for imprinting data on the film, and these are LE of FIG.
It corresponds to the D segment group 12.

Reference numerals 303, 304, and 305 denote seven segments for imprinting the photographing date data to be imprinted on the film. More specifically, 303 is the year of the photographing date,
Reference numeral 304 denotes a seven segment in which the month of the shooting day and the date of the shooting day are recorded.

Further, 306 is a dot segment together with 309 which indicates the photographing mode. When both the dot segments 306 and 309 are turned on, "manual AE" is turned on, the dot segment 306 is turned on, and the dot segment 309 is turned on. By turning off the light, "Tv priority"
Dot segment 306 goes out, dot segment 3
The light of 09 indicates "Av priority", and the light of both dot segments 306 and 309 indicates "program AE".

Further, 307 is a segment for imprinting the Tv value used at the time of photographing on the film, and 308 is a segment for imprinting the Av value used at the time of photographing on the film.

Further, 310 is a segment for projecting the exposure correction amount set at the time of shooting on the film, and 311 is a segment for projecting the focal length of the lens set at the time of shooting on the film.

Numerals 303 to 311 described above are segments showing the photographed data to be imprinted on the film as described above, and the data position to be imprinted on the film by these is 30.
Although it is outside the range of the screen that can be confirmed with the viewfinder shown by 2, it is a place that covers the image range 301 to be captured. That is, it is a position where a part of the segment overlaps the image shot on the film.

FIG. 4 shows an example of photographing when the data imprinting described above is performed.

The data to be printed on the film is 302
Outside the screen range that can be viewed with the viewfinder, the image is partially overlapped with the captured image. In addition, as an example of the imprinted data, the shooting date is “April 7, 1993”, the shooting mode is “Av priority”, the Av value is “8.0”, and the Tv value at this time is "1/2
000 ”, the exposure correction is“ +1.0 ”, and the focal length of the lens is“ 35 mm ”.

By performing the data imprinting as described above, it becomes possible to imprint more photographed data. Also, although there is a portion where the photographed data overlaps the photographed screen, it can be considered that there is no problem because it is outside the screen frame confirmed by the photographer in the viewfinder.

In this embodiment, the type of data is limited by using the segment-shaped LED segment group 12 for imprinting the data. However, when imprinting more data, during film feeding. It is more efficient to use the dot imprinting type.

(Second Embodiment) In the first embodiment described above, the data is imprinted in such a manner that a part of the image is superimposed on the photographed screen. However, the imprinted data is read depending on what is photographed. It can be difficult.

Therefore, in the second embodiment, when the data is imprinted, a part of the aperture is masked so that the data is imprinted in a readable form. In addition, a part of the mask of the aperture is a mask up and down along the screen frame that can be confirmed with the viewfinder, so that the screen confirmed by the viewfinder does not appear on the film due to the mask. .

Since the circuit structure of the camera is the same as that shown in FIG. 1, it is omitted here.

Next, the operation of the camera including the data imprinting of the camera according to the second embodiment of the present invention will be described with reference to the flowchart of FIG.

This operation is started from step 502 through step 501 when the switch SW1 which is turned on by the first stroke of the release button (not shown) is turned on. [Step 502] Photometry is performed using the photometry circuit 7.
In addition, the microcomputer 1 determines the Tv value based on the photometric data according to the mode set in the camera.
The Av value is calculated. [Step 503] The focus detection circuit 6 is used to measure the distance to the subject, and the microcomputer 1 communicates the lens drive amount to the lens control circuit 2 based on the measured distance data to drive the focus. [Step 504] Here, the release switch SW2
When is turned on, it is determined whether or not the release is permitted. As a result, if the release cannot be permitted, the process returns to step 502 and the same operation is repeated.
If the release is permitted, step 505
Go to. [Step 505] Here, the state of the release switch SW2 that is turned on by the second stroke of the release button is checked. If it is off, the process returns to step 502 and the same operation is repeated. If it is turned on, the process proceeds to step 506 to perform the release operation. [Step 506] The quick return mirror is moved up, and the Av value determined in step 502 is communicated to the lens control circuit 2 to narrow it down. [Step 507] Here, it is determined whether or not the data is set to be imprinted. Here, when the data is set not to be imprinted, the data imprinting LED segment group 12 is not turned on, and the process proceeds to step 510 for exposure and is set to imprint the data. Proceeds to step 508 in preparation for imprinting the data. [Step 508] The mask is driven by using the shutter control circuit 8 and the mask actuator 14 to mask part of the aperture so that the imprinted data can be easily read on the film.

At this time, the microcomputer 1
The sent mask amount is the amount of masking up and down the screen frame that can be confirmed with the finder. [Step 509] The data to be imprinted on the film is communicated to the data imprinting circuit 11, and the LED segment group 12
Control the lighting of. [Step 510] The front curtain of the shutter is started via the shutter control circuit 8 and the shutter front / rear actuator 13. [Step 511] T calculated in the above step 502
After a time period corresponding to the v value, the rear curtain of the shutter is started via the shutter control circuit 8 and the shutter front / rear curtain actuator 13.

As a result, the exposure operation for the predetermined frame of the film is completed. [Step 512] After the shutter travels, the quick return mirror is lowered and the shutter is charged, and the lens control circuit 2 is communicated with to return the aperture of the lens to the open state. [Step 513] Similar to step 507, it is determined whether or not the data is imprinted. If the date is not imprinted, the process proceeds to step 516 and the date is imprinted. If it is set so as to carry out the process, go to step 514 to confirm the end of the imprinting. [Step 514] It is checked whether or not the lighting of the data-imprinting LED segment group 12 started in step 509 is completed. As a result, if the LED segment group 12 is not lit for a time suitable for the ISO sensitivity of the film, the process waits until it is finished, and if the lighting is finished, the process proceeds to step 515. [Step 515] Since the imprinting of the data has been completed here, the mask is driven to the original position by using the shutter control circuit 8 and the mask actuator 14, and the state where the aperture is not masked is returned. [Step 516] One frame of photographed film is fed. Then, the process returns to step 502.

Next, with reference to FIGS. 6 and 7, a state of the mask at the aperture position described above will be shown.

FIG. 6 shows a state in which the aperture frame 600 is not masked. Note that 601 is a shutter.

Next, FIG. 7 shows a state in which the masks 602 and 603 are driven and masked on the aperture frame 600.

With the masks 602 and 603, the masked image does not appear in the file, but only the data imprint appears on the film. Also, the masks 602 and 603
Therefore, the image that does not appear on the film is an image outside the finder field that cannot be confirmed by the finder.

FIG. 8 shows the condition on the film photographed according to the second embodiment. Here, since the imprinted data and the photographed image do not overlap, the data is easy to read. Further, it is considered that there is no need to image on the film because the image that was not imaged on the film by masking the aperture is an image outside the field of view of the finder.

As an example of the data imprinted here, the photographing date is "April 7, 1993", the photographing mode is "Tv priority", and the Av value is "8.0". Has a Tv value of "1/500" and exposure compensation is "+0.5"
The step shows that the focal length of the lens is "100 mm".

In the second embodiment, the aperture is masked only when the data is imprinted. However, in the case of a camera in which it is highly necessary to imprint the data, the same operation is performed as when the frame of the aperture itself is masked. It is also possible to prevent the outside of the screen frame confirmed by the viewfinder from being printed on the film. As a result, the same state as in FIG. 8 can be obtained.

Further, when the data is imprinted, FIG.
As shown in (4), by masking the outside of the viewfinder, halfway characters do not overlap with the screen when the reversal film is mounted, and the captured screen becomes easier to see.

(Third Embodiment) In the above first and second embodiments, the case where the aspect switching (switching to panorama, high-vision size, etc.) is not performed has been described. In the third embodiment, the operation of the camera including the data imprinting when the aspect switching is performed will be described.

This operation will be described with reference to the flowchart of FIG. Since the circuit configuration is the same as that of FIG. 1, it is omitted here.

This operation is started from step 702 through step 701 when the switch SW1 which is turned on by the first stroke of the release button (not shown) is turned on. [Step 702] Photometry is performed using the photometry circuit 7.
In addition, the microcomputer 1 determines the Tv value based on the photometric data according to the mode set in the camera.
The Av value is calculated. [Step 703] The focus detection circuit 6 is used to measure the distance to the subject, and the microcomputer 1 communicates the lens drive amount to the lens control circuit 2 based on the measured distance data to perform focus drive. [Step 704] Here, the release switch SW2
When is turned on, it is determined whether or not the release is permitted. As a result, if the release cannot be permitted, the process returns to step 702 and the same operation is repeated. If the release can be permitted, the process proceeds to step 705. [Step 705] Here, the state of the release switch SW2 that is turned on by the second stroke of the release button is checked, and if it is off, the process returns to step 702 and the same operation is repeated. If it is turned on, the process proceeds to step 706 to perform the release operation. [Step 706] The quick return mirror is raised, and the Av value determined in step 702 is communicated to the lens control circuit 2 to narrow down. [Step 707] Here, it is determined whether or not shooting with the aspect switched.

Aspect switching means that the vertical direction such as panorama (vertical 13 mm, horizontal 36 mm) or high definition (vertical 20 mm, horizontal 36 mm) is 24 m.
It is shown that the image is taken in the upper and lower screen sizes that are shorter than m.

As a result of the above, if it is determined that the aspect switching has been performed, the process proceeds to step 709 to unconditionally imprint the data. On the other hand, if it is determined that the aspect switching has not been performed, the process proceeds to step 708. [Step 708] It is determined whether or not the data imprinting mode is set. If it is determined that the data imprinting mode is set, step 7
When it is determined that the data imprinting mode is not set, the process proceeds to step S09 without proceeding to turn on the data imprinting LED segment group 12. [Step 709] The data to be imprinted on the film is communicated to the data imprinting circuit 11, and the LED segment group 12
Control the lighting of. [Step 710] The front curtain of the shutter is started via the shutter control circuit 8 and the shutter front-curtain / rear-curtain actuator 13. [Step 711] T calculated in the above step 702
After a time period corresponding to the v value, the rear curtain of the shutter is started via the shutter control circuit 8 and the shutter front / rear curtain actuator 13.

As a result, the exposure operation for the predetermined frame of the film is completed. [Step 712] After the shutter travels, the quick return mirror is lowered and the shutter is charged, and the lens control circuit 2 is communicated with to return the aperture of the lens to the open state. [Step 713] Here, it is determined whether or not the data-imprinting LED segment group 12 is turned on in step 709. As a result, LED segment group 1
When 2 is turned on, the process proceeds to step 714, and when not turned on, the process proceeds to step 715. [Step 714] It is checked whether or not the lighting of the LED segment group 12 for data imprinting started in step 709 is completed. Here, if the LED segment group 12 is not lit for a time suitable for the ISO sensitivity of the film, wait until it is finished here, or if the lighting is finished, that is, if the data such as the shooting date is taken. If the imprinting has been completed, the process proceeds to step 715. [Step 715] Here, one frame of photographed film is fed. Then, the process returns to step 702.

FIG. 10 is a diagram showing a state when aspect switching (a panorama mask) is performed. Here, the masks 604 and 605 are masked to a panoramic size. The same parts as those in FIG. 7 are designated by the same reference numerals.

FIG. 11 is a diagram showing an example of data imprinting in the third embodiment.

As an example of the data imprinted here, the shooting date is "April 7, 1993", the shooting mode is "manual AE", and the Av value is "8.0". Tv value of is 1/1000, exposure correction is 0, and the focal length of the lens is 300 mm.

By adopting the configuration as in the third embodiment, it is wasteful to perform the aspect switching by automatically recording the data when the aspect switching is performed. It is possible to effectively use the upper and lower parts of the film.

According to the above-described first to third embodiments, the data position projected on the film is located outside the range of the screen which can be confirmed by the finder, but in the range of the photographed image. Therefore, it is possible to imprint more photographed data on the photographed frame.

Further, even if the film is separated between the frames, the photographed data is not lost and can be surely read.

[0076]

As described above, according to the present invention,
The film perforation position and the viewfinder view screen are provided between the perforation position of the film being fed and the upper and lower positions outside the frame forming the viewfinder view screen. The data is imprinted between the upper and lower positions outside the frame forming the.

Therefore, it becomes possible to imprint more data on the film without overlapping the data on the screen confirmed by the finder.

Further, according to the present invention, the imprinting means disposed between the perforation position of the film to be fed and the vertical position outside the frame forming the viewfinder screen, for imprinting data on the film surface. And a mask member for covering a part of the aperture so that the vertical screen outside the frame forming the viewfinder field screen is not projected on the film, and when the data is imprinted, the mask member is placed inside the aperture. And a mask member driving means for causing the mask member to move into the area, and the data is imprinted on a portion of the aperture which is partially covered by the mask member.

Therefore, more data can be imprinted on the film without the data overlapping on the screen confirmed by the finder, and the imprinted data can be easily viewed.

Further, according to the present invention, the imprinting means for imprinting the data on the film surface, which is disposed between the perforation position of the film to be fed and the vertical position outside the frame forming the viewfinder field screen. A mask member for covering a part of the aperture, an aspect switching means for driving the mask member to switch the screen size, and when the mask member is driven by the aspect switching means, the imprinting means is used.
