FIG. 7 shows the duo film F that has been photographed, but the side that is photographed first is the A channel and the return side is the B channel. FIG. 8 shows a microfilm rolled into a roll.

The first embodiment shows an example in which the camera unit is ejected and the display of the camera unit is switched to the B channel when the image capturing of the A channel approaches the end when the image is reciprocally photographed on a long microfilm.

In normal shooting (one-way shooting), a warning is only issued when the end of the film is approached, but in reciprocating shooting, it is necessary to prevent film exposure (fog) at the trailing edge of the film as is well known. Therefore, it is necessary to stop shooting at some point.

9 and 10 show the shooting state of the duo film. First, when the film is near the trailing edge (301a) of the film while shooting the A channel as shown in FIG. There is a possibility that it has already been exposed (301b) After stopping the shooting, after reversing the film (Fig. 10), reverse the moving direction of the film B
Move on to channel shooting. Here, the arrow indicates the traveling direction of the film.

11 to 13 show the states of the camera unit and the camera unit display as the recording section display means provided on the one end surface on the side opposite to the camera unit insertion direction. Reference numeral 303 is a number unique to the camera unit, 304 is a display indicating that the shooting state of the camera unit is A channel, 307 is a display indicating that it is B channel, 305 is a bar display indicating the approximate amount of remaining film in the camera unit, Reference numeral 306 is a display indicating that the film in the camera unit is locked so that it cannot be taken out.

FIG. 11 shows the camera unit during shooting of the A channel, and the film remaining amount (305) as shooting is performed.
Is decreasing. FIG. 12 shows the channel display (304, 307) set to the B channel by reversing the display of the camera unit because further shooting cannot be performed as the shooting progresses and approaches the rear end of the film. At this time, the camera unit is automatically ejected by the camera ejection mechanism, but the state of the camera unit is the same as in FIG. FIG. 13 shows a state in which the camera unit is ejected and then inverted and inserted to start photographing the B channel.

The discharge of the camera unit and the inversion of the display will be described with reference to the flowchart of FIG.

First, at 401, it is judged whether or not duo shooting is performed, and if it is not duo, this processing is not performed. If it is duo shooting, it is determined whether it is A channel shooting, and if B channel shooting is in progress, B channel shooting processing is performed (413), so details will be omitted here. In case of A channel photography, wait until the subject is fed (403), then feed the film (404) and photograph the subject (405) until the A channel reaches the rear end (near end) of the film. Wait (406). Near the trailing edge of the film (near end)
When it becomes, the feeding is interrupted at 407, and there is a wait until there is no subject being photographed (408), and at 409 the film feeding is stopped. After that, as shown in FIG. 12, the display of the camera unit is reversed to the B channel (410), the camera unit is ejected (411), and the B channel is displayed at 412. .

As described above, in the microfilm photographing apparatus for flipping the camera unit upside down for duo photographing, when the photographing of the A channel becomes the near end, the camera unit is automatically ejected and the display of the camera unit itself is changed to B. By reversing to the channel, the insertion direction of the camera unit becomes clear, and it is possible to prevent erroneous photographing such as continuing photographing of the finished A channel.

(Second Embodiment) FIGS. 15 to 17 show an example of a camera unit display section according to the second embodiment of the present invention.

FIG. 15 is a camera unit display when one-way shooting is performed with a normal camera unit, and the remaining film amount display 305 is a single bar display (305). FIG. 16 shows the camera unit display at the time of reciprocal shooting. In addition to the A-channel side film remaining amount display 305 of FIG. 15, a U-shaped return display (duo display) 30.
8 and B channel side film remaining amount display 309 are added 2
It is stepped. A channel side film remaining amount display 305
Decreases as the shooting progresses, and when the film is near the end of the film, the remaining film amount display on the A channel side becomes minimum. FIG. 17 shows a state in which the display of the A channel has been completed, the display has been reversed, and the B channel has been imaged. Since the filming of the A channel has been completed, the remaining film amount display 305 on the A channel side disappears but indicates that the reciprocal shooting is performed U
The character portion 308 is left as it is, and the film remaining amount display 309 on the B channel side decreases as the shooting of the B channel proceeds. In FIG. 16, the A channel is being photographed, but since the remaining film amount display is a U-shaped two-stage display, it is very easy to understand that the film photographing state is reciprocal photographing (duo photographing). Further, as shown in FIG. 17, since the U-shaped portion 308 remains even after moving to the B channel shooting, it is understood that the B channel of the reciprocal shooting (duo shooting) is being shot just by looking at the display of the camera unit. .

(Third Embodiment) FIGS. 18 and 19 show a connecting portion between a camera unit and an apparatus main body according to a third embodiment of the present invention.

In FIG. 18, reference numeral 40 denotes a camera unit, which is inserted along the camera guides 42a and 42b. On the camera unit 40 side, a contact point 320 with the apparatus main body is provided.

As described above, according to the configuration shown in FIGS. 18 and 19, the insertion direction can be automatically determined even when the reverse insertion is performed by the simple configuration in which the camera unit 40 has only one contact point.

(Fourth Embodiment) The camera unit 40 is turned upside down and reciprocally photographed on a microfilm (duo photographing).
In the image pickup apparatus for performing the above, correct image pickup cannot be performed if the insertion direction of the camera unit is wrong. Therefore, a method for preventing this will be described.

FIG. 20 is a flow chart for explaining the fourth embodiment of the present invention.

First, at 420, it is detected that the camera unit 40 is inserted, and then it is determined whether the photographing mode of the camera is one-way photographing or reciprocating photographing (duo photographing). In the case of reciprocal photographing (duo photographing), the channel to be photographed is judged in 422, and in the case of A channel photographing, the flow proceeds to 423. Even in the case of one-way shooting at 421, the process proceeds to 423. At 423, by checking the camera unit contact described above, A

A message indicating that the camera cannot be photographed due to the wrong mounting direction is displayed at 9, and the camera unit is ejected (430).

At 422, if B-channel imaging is to be performed, the flow advances to 427. At 427, it is determined whether the camera unit is inserted in the B channel shooting state by checking the camera unit contact point (428). If the camera unit is inserted in the A channel to be shot, the process proceeds to 425 and 426. . At 428 the camera unit is A
When it is inserted as channel imaging, the mounting direction is wrong, so the process proceeds to 429 and 430.

As described above, in a photographing apparatus for reciprocating photographing (duo photographing) on the microfilm by turning the camera unit upside down, a warning is displayed when the inserting direction of the camera unit is different and the camera unit is automatically operated. You can always take the correct picture by discharging it.

(Fifth Embodiment) The camera unit 40 is turned upside down and reciprocally photographed on a microfilm (duo photographing).
In the photographing apparatus for performing the above, when the photographing of the B channel is completed, the film is wound up and all the photographing is completed. The camera unit that has finished shooting starts shooting again from the A channel after exchanging the film. The state of the camera unit display at this time will be described with reference to the flowchart of FIG.

First, at 441, it is judged whether or not duo shooting is performed, and if it is not duo, this processing is not performed. If it is duo shooting, it is determined whether it is B channel shooting (442). If A channel shooting is in progress, A channel shooting processing is performed (4).
53). In the case of B channel photography, wait until the subject is fed (443), and then feed the film (44
4) and while shooting the subject (445), wait until the A channel reaches the rear end (near end) of the film (44
6). When the film is near the rear end (near end) of the film, feeding is stopped at 447, and there is no object being photographed (448), and at 449, the film is fed to the end and wound up. After that, as shown in FIG. 24, the display of the camera unit is returned to the A channel (450), the camera unit is ejected (451), and a display prompting to exchange a new film is displayed at 452.

22 to 24 show an example of the camera unit display of the fifth embodiment. FIG. 22 shows the camera unit during shooting of the B channel, but the B channel film remaining amount (309) shows as the shooting is performed. 23. As the number of images decreases, and as shown in FIG. When all the shooting is completed, the display of the camera unit is returned to the A channel as shown in FIG. 24 (3
From 04), the camera unit is automatically discharged by the camera discharge mechanism.

As described above, in the microfilm photographing apparatus for flipping the camera unit upside down for duo photographing, when the photographing of the B channel is completed, the camera unit is automatically ejected and the display of the camera unit itself is changed to the A channel. By returning to, the state of the camera unit and the next insertion direction are clarified, and the shooting can be continued correctly.

When the remaining capacity of the recording is low, the recording section is automatically detached, and by changing the display of the recording section to the other channel, the upper and lower insertion directions become clear, and the upper and lower sides can be mounted upside down. It is possible to prevent it. By displaying the remaining amount of the long recording medium that can be photographed into a U-shape, it is possible to display both one-way photographing and both-way photographing, and the remaining amount of the recording medium is U.
Since it is displayed in a letter shape, it is possible to check at a glance that the shooting state is reciprocal shooting (duo shooting).

Further, even if the device is mistakenly mounted upside down, the contact direction between the recording unit and the photographing apparatus main body is provided separately for the upper and lower sides, so that the mounting direction can be detected with a simple structure. By displaying a warning to that effect and ejecting the camera unit, it is possible to prevent shooting on the wrong channel.

By setting the remaining amount of film forward filming and the amount of remaining film filming available in two stages and providing a display device capable of displaying only one-way shooting or both reciprocal shooting depending on the display state of one stage, You can surely check the remaining shooting capacity and the status of the forward or return trip. By providing the camera unit with the display device, even when the camera unit is detached from the main body, it is possible to reliably confirm the remaining image-capable amount of the camera unit and the state of the outward or return route.

By providing the camera unit with a photographing lens, the lens of the camera unit itself can be used for photographing, and the magnification is fixed for the same film.

When the remaining film-capable amount of the film becomes extremely small, the camera unit is automatically detached from the main body of the image-capturing apparatus, and the display on the camera unit is switched to the opposite-direction recording so that the film-capable remaining amount of the film becomes very small. It can be clearly discerned that the camera unit is removed and the camera unit can be removed from the main body of the apparatus and then inserted again without mistaken upside down.
