Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographing device for photographing an image of a document and auxiliary information on microfilm.

A large number of originals are photographed on a long microfilm, the microfilm is cut to a predetermined length, the cut film (hereinafter referred to as a strip) is loaded into a jacket with multiple pockets, and a Go board is formed on the jacket. A method of creating a micro-fish in which a large number of pieces are arranged in a grid pattern is known. When creating a microfissure in this way,
It has been difficult to identify which strips should be inserted into the same jacket, leading to errors in inserting related strips into different jackets. Furthermore, even if the strip is correctly loaded into a jacket, there is a problem in that when the strip is pulled out from the jacket and then returned to its original position, it may be loaded into another jacket by mistake.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide an imaging device for creating microfilm that is easy to process and handle.

The present invention will be explained below with reference to the drawings.

This first counter 12 is preset to the number of originals when the number of originals is input to the first input circuit 10,
It subtracts and counts the photographing signal generated from the document photographing section in connection with the document photographing operation, and consists of an N-adic subtraction counter. As this photographing signal, for example, a signal generated from a photographing command button, a signal for driving a shutter that opens and closes an optical path for projecting the original, etc. can be used, and is generated each time the original is photographed. A known keyboard or the like is used for the first input circuit 10.

A decoder 13 outputs a signal when the count value of the first counter 12 reaches a predetermined value. This decoder outputs a signal when the number of originals input to the first input circuit 10 and the number of photographing signals input to the first counter match, that is, when the count value of the first counter becomes zero. Note that a comparison circuit may be provided in place of the decoder, the first counter may be configured as an addition counter, and the comparison circuit may compare the number of documents stored in the storage circuit with the contents of the addition counter. 1
4 is a one-shot multi-circuit that outputs a pulse signal when receiving an output signal from the decoder 13; 1;
Reference numeral 5 denotes a shutter drive circuit operated by a pulse signal from the one-shot multi-circuit 14, which opens the shutter 5 for a predetermined period of time when receiving the pulse signal.
Further, the pulse signal of the one-shot multi-circuit 14 is sent to the memory circuit 11, and upon receiving this pulse signal, the memory circuit 11 presets the stored number of documents in the first counter 12.

A second counter 16 counts the pulse signals of the one-shot multi-circuit 12, and is composed of an M-adic subtraction counter, which subtracts and counts the pulse signals. 17 is a second input circuit for inputting the number of jacket pockets;
A storage circuit 18 stores the number of pockets of the jacket input to the second input circuit. The second counter 16 is preset to the number of pockets when the number of pockets is input to the second input circuit 17. A decoder 19 outputs a signal when the count value of the second counter 16 reaches a predetermined value. This decoder 19
outputs a signal when the number of pockets input to the second input circuit 17 and the number of pulse signals generated from the one shot multi circuit 14 match, that is, when the count value of the second counter becomes zero. Note that a comparison circuit may be provided in place of the decoder 19, the second counter may be configured as an addition counter, and the number of pockets stored in the storage circuit 18 and the contents of the addition counter may be compared by the comparison circuit. 20 is a one-shot multi-circuit that outputs a pulse signal when receiving the output signal from the decoder 19; 21 is a third counter that counts the pulse signal of the one-shot multi-circuit 20;
22 is a display device that displays numbers corresponding to the count contents of the third counter 21; The third counter 21
It consists of a decimal addition counter, and the display 22 displays the count contents of the third counter 21 in decimal notation as a four-digit number. The numbers displayed on the display 22 are displayed on the display section 4 in FIG.

Next, the operation of the above device will be explained. Let N be the number of strips that can be stored in one jacket pocket. This number of frames N corresponds to the number of one unit of originals to be input to the first input circuit 10,
The number N of originals input to the first input circuit 10 is stored in the memory circuit 11 and preset in the counter 12. Further, if the number of pockets in the jacket is M, this number is input to the second input circuit and stored in the storage circuit 18. Next, the document to be photographed first of one unit of document group is placed on the document table, and the image of the document is photographed within the frame of the microfilm 3 by pressing the photographing command button. After the photographing is completed, the microfilm 3 is fed by approximately one frame. Next, the second document is placed on the document table, and the document is photographed in the same manner as described above. Each time a document is photographed, a photographing signal is generated from the document photographing section, this photographing signal is sent to the first counter 12, and the counter 12 subtracts and counts this signal.

When the first counter 12 subtracts and counts the photographing signal generated from the document photographing section when photographing the Nth document, that is, the last document of one unit of document group, the count content of the first counter 12 becomes zero. One shot multi circuit 1 via decoder 13
A pulse signal is generated from 4. This pulse signal is subtracted and counted by the second counter 15. On the other hand, the shutter 5 is opened via the shutter drive circuit 15 in response to a pulse signal from the one-shot multi-circuit 14.
A display 22 is placed on the side of the frame where the last original is photographed.
The displayed number will be photographed. Note that the original and the contents of the counter 15 are photographed on microfilm simultaneously or sequentially. Therefore, the contents of the counter 15 are photographed on the microfilm only when the last document of one unit of document group is photographed. At this time, it is assumed that the number "0000" is displayed on the display 22. On the other hand, the pulse signal from the one-shot multi-circuit 14 is sent to the memory circuit 11, whereby the number N of originals stored in the memory circuit 11 is again preset in the first counter 12. Next new 1
Photographing of a group of original documents (the number of original documents is the same as the one unit described above) is performed in the same manner as described above. Then, when photographing the last document in the new document group, display 2
The display number 2 "0000" is recorded on the microfilm in the same manner as described above. Thereafter, in the same way as described above, the same number is photographed on the side of the frame every time the last document of one unit of document group is photographed. The number of pockets preset in the second counter 16 is subtracted each time one unit of document group is photographed, and when one unit of document group is photographed a predetermined number of times, the count value of the second counter 16 becomes zero, and at this time One shot multi circuit 20
A pulse signal is output from , this pulse signal is added and counted by the third counter 21, and the displayed number on the display 22 becomes "0001". As a result, when a new group of documents is photographed next, the number "0001" displayed on the display 22 is recorded on the microfilm when the last document of the group of documents is photographed. Therefore, a number is recorded on the last frame of every certain number of frames on the microfilm, and the same number is recorded on the microfilm stored in the same jacket (which is cut into strips with the number of pockets). Each jacket will have a different number.
Therefore, the number C-1 is recorded on the microfilm accommodated in the C-th jacket. Note that the displayed numbers may start from "0001".

Fig. 3 shows a microfilm produced by the above-mentioned device, in which originals are photographed sequentially starting from the left frame in the figure.
The last frame of the unit manuscript group is indicated by A, and this A
The numbers displayed on the display 22 are recorded on the sides of the pieces as organizing information. B indicates the last frame of one unit of document group stored in another jacket, and a different number from the above is recorded on the side of this B frame.

The microfilm 3 is cut along line a on the right side of the serial number, and each strip has the same number of frames and the same length. This strip is the fourth
The jacket shown in the figure is loaded. Figure 4A,
B shows a jacket loaded with strips. The jacket consists of two transparent sheets and has four pockets 20 ₁ to 20 ₄ for storing the strips.
Each pocket is closed on three sides and has an entrance on the remaining side for inserting and removing the strip, and the strip is inserted through the entrance of each pocket. A connecting reference number is attached to the upper right corner of each jacket.

It should be noted that the jacket is not limited to the above-mentioned embodiment, and there are various jackets such as those to which a strip is attached, and any of these jackets can be used. When loading each strip into a jacket, each strip can be correctly loaded into the designated jacket by inserting the strip into the pocket of each jacket so that the serial number on the jacket matches the number recorded on the strip. .

As described above, the microfilm can be correctly cut at a predetermined location, and the cut strip can be correctly loaded into a predetermined jacket.

Note that in the above embodiment, the display information on the display is photographed when photographing the last document of one unit of document group, but it is also possible to photograph the display information when photographing the first document. good.

In the above embodiment, if the number of originals that can be accommodated in one pocket of the jacket differs, the number of originals input to the first input circuit is changed, and if the number of pockets of the jacket differs, the number of originals is input to the second input circuit. Try changing the number of pockets.

FIG. 5 shows another embodiment of the display, in which character information such as alphanumeric characters (A, B, C, . . . ) corresponding to the count of the third counter 21 is displayed on the display 22'. 23 is a code conversion circuit that converts the count value of the third counter into a code.

As described above, in the present invention, the same serial number is recorded in the portion corresponding to each strip of microfilm to be inserted into the same jacket.
After processing, the microfilm is cut into predetermined lengths and the cut strips of predetermined length are inserted into each pocket of a jacket for storage.
Strips to be inserted into the same jacket can be easily identified by the rearranging numbers recorded on each strip, and the work of rearranging the strips after photographing is facilitated. As a result, the accident of inserting the strip into the wrong jacket can be prevented. Furthermore, even if any strip is pulled out of the jacket after each strip has been inserted into a given jacket, the strip can be correctly returned to its original jacket.
