Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for recording an image of a subject on a long recording medium such as a microfilm.

0002

2. Description of the Related Art Conventionally, a rotary camera is known as a typical example of this type of recording device. The camera will be described below as an example.

This rotary camera sequentially conveys objects to be photographed one by one, such as bills, checks, stock certificates, and general documents, to be microfilmed and preserved, and sequentially photographs the image information of the objects onto a long film. However, it is an automatic photographing device that discharges the photographed subject out of the device, and it is possible to quickly record a large number of images of the subject on a long film set inside the device.

[0004] For this reason, for example, in financial institutions such as banks and general offices, microfilms are used to store and organize various materials and documents, and to prevent accidents.

By the way, depending on the purpose of use, such as storing important materials or performing frequent searches, in addition to the original film, it is necessary to use a duplicate film, etc., which is a copy of the original film, in consideration of safety in film storage. .

Conventionally, a duplication device is used to make a duplication film that is a copy of an original film, but instead of using a duplication device, two long films are set in the camera at the time of shooting, and the two long films are A two-film rotary camera is known that is capable of simultaneously capturing and recording exactly the same subject image on a single film.

[0007]

[Problem to be Solved by the Invention] However, in the above-mentioned conventional double-shot photographing device, depending on the user, the type of subject (material) to be photographed, or the purpose of using the microfilm, it may not be necessary to take two shots of the film. In some cases. For example, in cases where storage stability is not required or there is no need to perform retrieval, one original film is sufficient, taking into consideration the economic efficiency of the film.

[0008] Therefore, in such a case, the photographing device for two shots is used with only one film, so
This has the disadvantage that space is wasted and the two-shot imaging device cannot be used effectively.

[0009]

[Means for Solving the Problems] In order to be able to effectively record images on a plurality of recording media, the present invention provides a drive means for independently driving the plurality of recording media, and a drive means that detects the remaining amount of each recording medium. a recording means for recording an image on each recording medium; and a means for switching to perform recording on the other recording medium when the detection means detects that the remaining amount of one recording medium has reached a predetermined amount. It is characterized by having the following.

54 are provided. Also, the supply shaft 42 and the take-up shaft 4
7 is provided with a friction mechanism (not shown), and even if the film winding diameters of the supply reel 43 and the take-up reel 48 change, it is possible to convey the film F while maintaining an appropriate tension.

FIG. 3 is a flowchart of this embodiment. In the above configuration, films are respectively loaded into the two film storage sections 41 and both are attached to the main body. First, it is assumed that the upper film storage section 41 is used for photographing. In this case, the electromagnetic clutch 57 is turned ON (step 2) by the photographing start command (step 1), and the electromagnetic clutch 58 is turned on (step 2).
By turning OFF, the drive from the main body 50 is transmitted only to the drive gear 53, making it possible to drive only the upper film storage section. Thereafter, as the shooting progresses, when the amount of film in the upper film storage section 41 reaches a predetermined amount (set to no more film or an amount close to it), the electromagnetic clutch 57 is turned off (steps 3 and 4). (Step 5), prohibiting photography into the upper film storage section, and then turning on the electromagnetic clutch 58 to similarly drive only the lower film storage section 41 and take pictures into the lower film storage section. to continue shooting (steps 6 and 7). Similarly, photography can be continued in the lower film storage section 41 until the film runs out. (Steps 8, 9, 10, 11)
Also, while shooting in the lower film storage compartment, take out the upper film storage compartment that has already been photographed and change the film.
By attaching it to the main body of the apparatus again, it is possible to continue photographing in the upper film storage section in the same way after the completion (cancellation) of imaging in the lower film storage section.

In addition, in this embodiment, a photographing apparatus for taking two films with two film storage sections has been described as an example, but it is also possible to take pictures and record on a plurality of films with three or more film storage sections. In a photographing device, each film can be photographed sequentially in a similar manner.

The remaining amount of film during shooting is determined by encoders 421, 453 and photo interrupters 422, 454 provided on the supply shaft 42 and capstan roller shaft 451 in the camera section 40, in synchronization with the rotation of the respective shafts. The remaining amount of film F on the supply reel 43 can be detected by measuring the time intervals of the pulses generated by each pulse using a measuring means and comparing these measured time intervals and their changes. That is, as the film F is sequentially conveyed and the film winding diameter of the supply reel 43 becomes smaller, the rotation of the supply shaft 42 becomes faster. Completion can be detected.

The remaining amount detecting means is not limited to the above-mentioned embodiment, and various known methods can be adopted.

Furthermore, the recording medium is not limited to microfilm, and various other recording media can be used.

FIG. 4 shows another embodiment of the invention.

This embodiment has the same configuration as the first embodiment described above, but in the above embodiment, when the remaining amount of film in one camera reaches a predetermined amount and shooting is completed, the other camera In contrast, in this embodiment, while one film storage section is shooting or just before the shooting is completed, the other film storage section is driven to switch the film. By carrying out leader feeding, after the completion of photographing in one film storage section, it is possible to immediately start photographing in the other film storage section. Furthermore, continuous sequential photographing is possible by transporting the films in the first film storage section to the trailer at the point when photographing is started in the other film storage section.

In other words, even if the subject is in the middle of being fed or conveyed when switching from one film storage section to the other, it is possible to efficiently transfer the image without stopping the feeding or conveyance of the subject. You can take pictures sequentially.

Further, as shown in FIG. 4, the leader feeding of the film is carried out by using a reflector provided on the camera guide member 50a or 50b of the apparatus main body 50 when the film storage section 41 in which the film is set is mounted on the apparatus main body. The film storage portion detection means 70, 71 such as a type photo sensor detects that the film storage portion 41 is attached to the main body 50, and the electromagnetic clutches 57, 71 are activated by this detection signal.
By turning on the switch 58 and driving each film storage section, it is possible to perform the operation of the film storage sections more smoothly and efficiently when switching between images.

When it is necessary to record the same subject on two films at the same time, that is, when creating a duplex film at the same time, the duplex shooting mode is set so that the clutches 57 and 58 for driving both films are turned on at the same time. By switching to , it is possible to shoot two images at the same time as before.
When photographing is to be carried out independently, it is sufficient to switch to the independent photographing mode so that each film can be photographed independently as in this embodiment.

FIG. 5 shows yet another embodiment of the present invention.

This embodiment has the same configuration as the first and second embodiments described above, but includes a known information imprinting means (not shown) such as an LED provided on or near the optical path of the subject.
As shown in FIG.
It shows that photographing was continued in the rear part l1 of the final image Pe and the front part l2 of the first image Pf of the next film F2 after the photographing change. Index data such as marks and film numbers are automatically input after the end of photography and before the start of photography. The data may be imprinted while one of the films is being photographed.

By imprinting marks, data, etc. as described above on the film during sequential photographing, it is possible to easily check, search, etc. on the film after development.

[0030]

[Effects of the Invention] As explained above, according to the present invention, not only can recording be performed simultaneously on a plurality of recording media, but even when simultaneous recording is not necessary, recording can be performed separately on each recording medium. When one recording medium runs out and recording is finished, it is possible to immediately continue recording to the other recording medium without the troublesome operation of replacing and reloading the recording medium. The usability is improved and the recording device can be used effectively.
