In the first embodiment, when a leader is fed to a portion of the long microfilm which has been exposed to external light before the start of image capturing, this is canceled as shown in FIG. An example is shown in which the blocking member is moved to the right as shown in FIG. 7 by driving the shown lock releasing solenoid 70 and the lock mechanism of the camera lid 51 is released.

This is because, for example, when a different film having a different thickness is erroneously set and the leader feeding is started, as described above, this is interrupted and the lid releasing lever 54 of the camera lid 51 is released. Is not blocked by the blocking member 56.

FIG. 12 shows the front end portion of the film which has been subjected to normal photographing, and FIG. 13 shows an example of the film showing the first embodiment. In FIG. 12, the leading end of the film from the leading end 300 to the portion or the portion 301 is exposed by external light when the film is loaded. Therefore, first, the image can be taken unexposed by the leader feeding 302.
After the film is transferred to, the photographing of the image 303 or the mark 304 is started. Therefore, as shown in FIG. 12, the film portion 3 in which an image is not photographed at the leading end portion of the film
Although there are 00 to 302, the reduction rate in microfilm photography is extremely high, and therefore it takes a lot of time to feed this reader. When the leader feed is completed, shooting is possible, and the lid release lever 54 of the camera lid 51 is locked by the blocking member 56, so that the camera lid 51 cannot be released. The shaded area is where it was exposed to external light.

In FIG. 13, after the leader feeding from the film front end 300 is started and the mistake in the film thickness or the like is noticed and the film transfer does not reach 302,
Use the keyboard 127 to instruct leader feed interruption 3
It is assumed that the film transfer is stopped at 05. At this time, since the position of 305 on the film has already been exposed by the external light as shown in FIG. 13, an image cannot be taken. Therefore, when the leader feeding is interrupted, photographing is disabled, the lid release lever 54 of the camera lid 51 is not blocked by the blocking member 56, and the camera lid 51 can be released.

A series of operations will be described with reference to the flowchart of FIG.

First, in step 400, a long film is loaded in the camera section 40, and in 401, the camera section lid 51 is closed. Next, at 402, when a leader feed instruction is issued from the keyboard 127 of the control unit 126, at 403 the film drive control circuit 208 causes the film drive motor 20 to move.
9 is driven to start the film transfer. At this time, 40
4 confirms the leader cancel request from the keyboard 127. If there is no request, the pulse from the film encoder 205 is sent to the film transfer amount measuring circuit 21 at 405.
The measurement is performed at 0, and if the distance for the predetermined leader has not been transferred at 406, steps 404 to 406 are repeated. 40
If the predetermined distance is reached at 6, the leader feed is stopped at 407, the lid release lever 54 is locked at 408 to prevent the lid from being released, and then shooting can be started at 409. When an instruction to cancel the leader feed is issued from the keyboard 127 at 404, the film transfer is stopped at 410, and when the camera unit lid release lever 54 is already locked at 411, the camera unit lid release lever 54 is locked at 412. Is canceled and photographing is prohibited at 413.

With the configuration as described above, in the present embodiment, when the leader feeding before the start of shooting is canceled, the lock of the camera lid is released and the shooting is not possible. It is possible to prevent an image from being accidentally taken where it has already been exposed to external light.

[Second Embodiment] FIGS. 15 to 18 show a second embodiment of the present invention.

In the second embodiment, after the filming of a long microfilm image is completed, a trailer feed is performed to prevent the filmed image from being exposed to outside light when the film is taken out of the camera section 40. In this case, an example of controlling the lock mechanism of the camera lid 51 when canceling this will be described.

This is, for example, when the trailer feed is started even though there are still subjects to be photographed, in order not to waste film and time, this is interrupted and the lid of the camera lid 51 is stopped. The body release lever 54 is blocked by a blocking member 56 so that photographing can be continued.

FIG. 15 shows a portion from the center to the end of photographing of a film which has been normally photographed, and FIGS. 16 and 17 show an example of the film showing the second embodiment. In FIG. 15, images are continuously shot in the central portion of the film, and in the shooting end portion, the image is shot up to 306, the film feeding is stopped, and the shooting is finished. At this time it is still 306
Subsequent films have not been exposed.

FIG. 16 shows an example of a film in which the film is taken out of the camera unit 40 after the trailer is fed to 308 after the photographing is finished, and the portions 307 to 308 after the photographing ending portion are exposed by the external light. In FIG. 16, in the vicinity of the final image 304, an image that is normally exposed without the influence of external light is recorded.

FIG. 17 shows an example in which the trailer feeding is started after the photographing is finished, but the film is fed to 309, and then the feeding is interrupted to take out the film. In this example, since the film was exposed to outside light after the filming was finished and the amount of film transfer was insufficient, the final image 310 was exposed by the outside light and was not a normal image.
The second embodiment prevents this state, which will be described with reference to the flowchart of FIG.

First, an image of the subject is photographed at 420, and 421
And wait for the end of shooting. 422 when the subject is finished shooting
Stop the film transfer at, and at 423, control unit 1
When an instruction to feed the trailer is given from the keyboard 127 of 26, at 424, the film drive control circuit 208 drives the film drive motor 209 to start the film transfer.

If there is no request for canceling the trailer feed from the keyboard 127 at 425, the pulse from the film encoder 205 is measured at the film transport amount measuring circuit 210 at 426, and at 427, the predetermined trailer distance is still transported. If not, 425 to 427 are repeated.
If the predetermined distance is reached at 427, the trailer feeding is stopped at 428, the lid release lever 54 is unlocked at 429 to release the lid lock, and then at 430, the shooting ends. When an instruction to cancel the trailer feed is issued from the keyboard 127 at 425, the film transfer is stopped at 431, and at 432, the camera body lid release lever 5 is released.
If 4 is not locked yet, the camera unit cover release lever 54 is locked at 433, and shooting is further continued at 434.

As described above, according to this embodiment, in this embodiment, when the trailer feeding after the photographing is canceled, the camera unit cover release lever 54 is released.
Since it is locked, the problem of exposing the captured image with external light by accidentally releasing the camera lid in that state is prevented, and shooting can also be continued normally. .

[Third Embodiment] FIGS. 19 to 22 show a third embodiment of the present invention.

In the third embodiment, the photographing of a long microfilm image is temporarily stopped, and the film is space-fed to make a space between one image and the next image. An example of controlling the lock mechanism of the cover 51 will be described.

This is, for example, to prevent film and time from being wasted when there is a subject to be continuously photographed but the space feeding is started, so that this is interrupted and the lid of the camera lid 51 is stopped. The release lever 54 and the blocking member 5
It is cut off at 6 so that shooting can be continued.

FIG. 19 shows the vicinity of the center of the film on which normal photographing has been performed. In FIG. 19, images are continuously photographed at the central portion of the film, and images 311 and 311 are photographed up to 311 and the rear of the image is photographed. Not exposed.

FIG. 20 shows an example in which the subject is photographed up to 311 and, thereafter, space feeding is performed up to 312, a photographed image interval is provided, and images are normally photographed continuously from 312.

In FIG. 21, after photographing the subject up to 311
Space feeding was started, but this was interrupted at 313, and the lid 51 of the camera unit 40 was once opened, so image 310
And 313 is an example in which the influence of external light has appeared.

Although the photographing is normally continued after the space feeding, the lid release lever 54 is shut off even when the space feeding is interrupted so that the photographing can be continued normally. is there. This example will be described with reference to the flowchart of FIG.

First, at 440, an image of the subject is taken, and 441
To continue shooting the subject. If the shooting of the subject is not continued, the film transfer is stopped at 442 and 443
If there is a space feed instruction from the keyboard 127 of the control unit 126, the film drive control circuit 208 drives the film drive motor 209 to start film transfer at 444. If there is no request from the keyboard 127 to cancel the space feed at 445, the pulse from the film encoder 205 is measured at the film transport amount measuring circuit 210 at 446, and at 447 if the predetermined space distance is not yet transported, 445 to 447. repeat. If the predetermined distance is reached at 447, the space feed is stopped at 448, the lid release lever 54 is shielded and the lid 51 is locked at 449, and further photographing can be continued at 450.

When an instruction to cancel the space feed is issued from the keyboard 127 at 445, the film transfer is stopped at 451. If the camera lid release lever 54 is not locked at 452, the camera lid release lever 54 is opened at 453. Lock and continue shooting.

As described above, with this configuration, in this embodiment, since the camera unit lid release lever 54 is locked when the space feed for canceling the shooting is canceled, the state is kept in that state. By accidentally releasing the camera body cover 51, the problem of exposing an already-taken image with external light or taking an image on a film exposed by external light is prevented, and the image is taken. You can continue normally.

In the embodiment, when the film transfer such as the leader transfer or the trailer transfer is canceled, the cancellation may be displayed on the display 128 of the control unit 126.

Although space feeding is taken as an example here, it is not limited to space feeding, and if the lid 51 is always locked when it is canceled during the transfer of the film, the lid is mistakenly closed. You can prevent the body from opening.

In FIG. 23, images are continuously photographed in the central portion of the film, and when it reaches 314, the image 310 is photographed. By the way, the shooting was finished near the end of the film.

When the film is near the end of the film, normally, the photographing is stopped, the trailer is fed, and then the film is taken out from the camera section 40 and developed. An example of the film at this time is shown in FIG. 24, and the portion exposed by external light after 314 is shown by hatching.

In FIG. 25, the trailer feeding is started after the photographing is near the trailing edge of the film, but the trailer feeding 316 is canceled to photograph the subject for which the photographing is forgotten, and the images 317 and 318 are photographed. This is an example in which the film is fed from the film, taken out, and developed. The portion exposed by the external light is the same as in FIG. 24, but the images 317 and 318 are abnormally exposed images as shown in FIG. An example in which the above-mentioned problem does not occur in the fourth embodiment will be described with reference to the flowchart of FIG.

First, at 460, an image of the subject is taken and 461
The film transfer is continued with, and the subject photographing is continued with 462. If the subject is not continuously photographed, it is determined at 463 that the film is near the end, and if it is near the film end, the film transfer is stopped at 464 and the trailer feed instruction is awaited. When a trailer feed instruction is issued from the keyboard 127 of the control unit 126 at 465, 466
Then, the film drive control circuit 208 drives the film drive motor 209 to start the trailer feeding. 467
Even if there is a request to cancel the trailer feed from the keyboard 127, the film feed is not stopped (473).
In 468, the pulse from the film encoder 205 is measured by the film transfer amount measuring circuit 210, and in 469, if the predetermined distance has not been transferred yet, 467 to 469 are repeated. If the predetermined distance is reached in 469, the trailer feed is stopped in 470, the lock of the lid release lever 54 is released in 471, and then the photography ends in 472.
