Thus, the image quality of the film can be prevented from being deteriorated by the repetition of copying.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a copying apparatus for copying the contents of an original film onto another film.

B. Prior art and its problems For example, copying apparatuses have been known that copy negative information formed in the exposed area of a photographed original film onto another copying film.

However, after copying, the copying film is used as a new original and the negative information is copied onto another film.
If the operation of copying the negative information onto another film is repeated, the image quality of the copied negative information gradually deteriorates and eventually becomes unwatchable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a copying apparatus that records the number of repetitions of copying described above in correspondence with the exposure area to prevent deterioration in image quality.

Means for Solving Problem C6 To explain with reference to FIG. 1, which is a diagram corresponding to the claims, the present invention provides a copying apparatus equipped with a copying means 103 for copying an arbitrary exposed area of an original film 101 onto a copying film 102. Applicable. And the problem mentioned above is that the original film 1
A copying apparatus in which a history storage unit 104 that stores a copy history for an arbitrary exposure area of 01 in correspondence with this exposure area is set in pair with an original film 101,
A reading unit 105 reads out the history set in the history storage unit 104 when copying the original film 101, an updating unit 106 updates the read history, and the updated history is stored in the history storage of the copying film 102. Part 1
This problem can be solved by a copying apparatus equipped with a recording means 108 for recording data in 0.07.

01 action reading means 105 reads the history of the history storage section 104 when copying the original film 101, and updates the history of the original film 101 to the updating means 10.
6 updates the read history.

The recording means 108 records this updated history in the history storage section 107 of the copying film 102.

For example, if copying is prohibited when the number of copies based on the read history is greater than or equal to a predetermined value, deterioration in image quality of the film due to copying can be prevented.

E. Embodiment An embodiment of the present invention will be described based on FIGS. 2 and 3.

FIG. 2 shows the overall configuration of a copying apparatus according to the present invention, in which light emitted from a diffused light source 1 passes through an original film 2 set at a copying position and a projection lens 3, and then passes through an original film 2 set at a copying position and a projection lens 3. It reaches the copying film 4 through a mask (not shown) provided between the copying film 4 and the copying film 4. This mask is for guiding light only to the exposure area 4a of the copying film 4. As a result, the photographic information of the exposure area 2a of the original film 2 is copied to the exposure area 4a of the copying film 4.

R-RN indicate light-receiving elements, and original film 2
Mark M is imprinted on the margin corresponding to each piece of
The presence or absence of each of 1□ to M1N is detected.

That is, these light-receiving elements R□ to RN detect each mark M1□ to MIN when the original film 2 is loaded into the copying machine.
are placed directly below the imprint position. Therefore, if the marks M11 to MiN are imprinted, the light from the light source 1 will not pass through that part, so the light will not reach the light receiving elements R to RN, and the marks M11
If ~M iN is not imprinted, the light passes through and reaches the light receiving elements R□~RN. The light receiving elements R1 to RN are connected to the CPU 5, and output a high level signal when receiving light from the light source 1, and output a low level signal when not receiving light.

The above-mentioned N marks M11 to M1N indicate various kinds of photographing-related information for the exposure area of each frame.

This photographing-related information includes information indicating the number of copies or the number of trimmings, that is, information indicating the history of copying.

In this case, the number of copies is, for example, when considering the original film 2 as a photographed film, the photographing information of the exposure area 2a is copied to the exposure area 4a of the copying film 4, and the exposure of this copying film 4 is When the operation of copying the photographic information of the area 4a to an arbitrary exposure area of another copying film is repeated, it represents the number of times the operation is repeated.

Also, the number of times of trimming means that when the original film 2 is considered to be a photographed film, a part of the exposure area 2a is enlarged and copied to the exposure area 4a of the film 4, and the copied exposure area 4a is When a portion is further enlarged and copied to an arbitrary exposed area of another film, this indicates the number of times the operation is repeated.

Furthermore, in the photographic information based on the mark spacing □ to M1N, for example, when copying the photographic information of the exposure area 2a onto another copying film, or when printing on photographic paper with another enlarger, the exposure area It also includes information specifying whether to copy or print the entirety of 2a, or to enlarge and copy or print a portion of it (trimming print), and information specifying the printing range at that time.

Further, N light emitting elements W to WN consisting of LEDs etc. are connected to the CPU 5, and marks M are placed on the margins of the copying film 4 based on an imprint command signal from the CPU 5.
Imprint 21~M2N. The marks M2□ to MzN represent various kinds of photographing-related information, as described above.

Furthermore, a lens drive circuit 6 for the lens 3 and a buzzer warning device 7 are connected to the CPU 5.

The lens drive circuit 6 drives the lens 3 to either a normal copying position or a trimming copying position, which will be described later, in response to a lens drive signal from the CPU 5.
A warning sound is generated in response to the warning signal from U5.

Next, the control procedure of the CPU 5 will be explained based on the flowchart of FIG.

In FIG. 3, first, in step S1, arbitrary exposure areas 2a of the original film 2 and the copying film 4,
4a to the copy position. In this embodiment, the history storage section is provided in the margin of the film, so when the films 2 and 4 are set in the copying machine, the history storage section is also set.

Next, in step S2, the output signals from the light receiving elements R□ to RN are read, and the exposure area 2a of the original film 2 is
The photographing related information corresponding to is recognized and the process proceeds to step S3. In step S3, from this information, the number of copies n of the exposure area 2a mentioned above is set to a predetermined limit value X of the number of copies
Determine whether it is smaller than . Here, this limit value or a value is set such that if further copies are made, the image quality of the printed image will deteriorate to an extent that it cannot be viewed.

If step S3 is affirmatively determined, the process proceeds to step S4,
The number of copies performed this time "1" is added to the number of copies n, that is, the number of copies is updated, and the process proceeds to step S5.

In step S5, it is determined whether trimming is necessary based on the read photographic information. If denied, step S
9, and if the answer is yes, the above-mentioned trimming number i is set to the predetermined trimming number limit value Y in step S6.
Determine whether it is smaller than .

Here, this limit value Y is set to a value such that if copying by trimming is performed any further, the image quality of the printed image of the exposed area 4a will deteriorate to such an extent that it becomes unwatchable.

Generally, in copying by trimming, a part of the exposure area is enlarged and copied, so the resolution is lower than in normal copying, and the image quality is further deteriorated. Therefore, the limit value Y of the number of times of trimming is set to a value smaller than the limit value X of the number of copies mentioned above.

If step S6 is affirmed, the process proceeds to step S7, and the number of times i is trimmed is equal to the number of times the current trimming is performed.
” is added and the process proceeds to step S8.

In step S8, a lens drive signal is output based on the information regarding the trimming range among the photographing related information read in step S2, and the projection lens 3 is driven to the corresponding trimming copying position via the lens drive circuit 6. . Next, in step S9, the light source 1 is made to emit light to perform exposure. As a result, the negative information of the exposure area 2a is changed to the exposure area 4a.
is copied to.

Next, the process proceeds to step S10, in which photographing-related information including the number of copies and the number of times of trimming is recorded in the margin of the exposure area 4a. That is, an imprint command signal is output to cause the light emitting elements W□ to WN to emit light, and a predetermined mark among the marks M21 to M and H is imprinted, and the process proceeds to step Sll. In step Sll, the original film 2 and copying film 4 are fed by one frame, and then in step S12 a lens drive signal is output, and the lens 3 is driven to the normal copying position via the lens drive circuit 6, and step S13 Proceed to.

In step S13, it is determined whether or not copying has been completed. If the answer is affirmative, the process is terminated, and if the answer is negative, the process returns to step S2 and the above-described process is repeated.

Further, if step S3 is negative, that is, if the number of copies n is greater than or equal to the limit value X of the number of copies, step S1
4, a warning signal is issued and the warning device 7 generates a warning. Next, the process advances to step S15, and it is determined whether or not to force copying. Here, if the operator operates, for example, a button that instructs to stop copying in response to the warning in step S14, step S15 becomes negative, whereas if the operator operates a button that instructs forced copying, step S15 becomes affirmative. If an affirmative determination is made in step 815, the process advances to step S6.
If the determination is negative, the process proceeds to step 81B. On the other hand, if step S6 is negative, that is, if the number of trimming times i exceeds the limit value Y of the number of trimmings, the process proceeds to step 816 and a warning is generated. Determine whether or not to force copying. If the determination is affirmative, the process proceeds to step S8, and if the determination is negative, the process proceeds to step S81B.

In step 818, the copying film 4 is fed by one frame, and the process advances to step S12.

According to the above procedure, when copying, the photographing-related information of the exposure area 2a of the original film 2 is first read, and at the time of copying, the CPU 5 calculates the number of copies of the photographing-related information.
In other words, rlJ is added, and the updated photographic information is recorded on the copying film 4. If the number of copies read n is equal to or greater than the limit value X, a warning is generated to notify that the image quality will deteriorate if copies are made any further.

At this time, if the operator takes steps to stop the copying, the copying will not be performed, thereby preventing the image quality from deteriorating.

Further, even if the number of copies has not reached the limit value X, if the number of times of trimming has reached the limit value y (y<X), a warning is issued in the same way as described above. At this time as well, if the operator takes steps to stop copying, copying will not be performed and deterioration in image quality will be prevented.

In the configuration of the above embodiment, the light receiving elements R□ to RN serve as the reading means 105, the light source 1 and the projection lens 3 serve as the copying means 103, the CPU 5 serves as the updating means 106, and the light emitting elements W to WN serve as the recording means 107. Configure each. Further, a portion of each film 2.degree. 4 into which information regarding the copying history is imprinted corresponds to a history storage section.

Note that in the above, a warning is generated when the number of copies n is equal to or greater than the limit value X, and a similar warning is generated when the number of times of trimming i is equal to or greater than the limit value Y even when the number of copies is equal to or less than the limit value X. For example, a value nXi is calculated by multiplying the number of copies n by the number of trimming i, and this value is, for example, both the limit values X, Y
A warning may be issued when the multiplied value is greater than or equal to X-7.

Further, the prohibition may be forcibly prohibited at the same time as the warning, or the prohibition may be simply prohibited without giving the warning.

Furthermore, the above example shows an example in which shooting-related information is stored in pairs with the film by imprinting a mark indicating the copying history in the margin of the film. Even if a separate device is provided for storing the information, the photographing-related information is stored corresponding to each exposure area. Further, in this case, it is necessary to separately provide a mechanism for setting an IC card or a film cartridge in the copying apparatus.

Furthermore, although an example of copying a roll film with a large number of exposure areas has been shown, the present invention is not limited to this, and can also be applied to copying a cut film with an exposure area of only one frame. The information may be positive information.

F8 Effects of the Invention According to the present invention, when copying a film, the history of copying of the original film is updated and recorded on the copying film. If copying is prohibited in this case, deterioration in film image quality due to repeated copying can be prevented.
