Description

The present invention relates to a data recording system used in a microscope or the like.

[Conventional technology]

A recording device for a microscope, which is attached to a microscope and captures an image of the image, is conventionally known. In the case of microscopic photographing, various data are required for evaluating a microscopic photograph to be completed later. For example, the eyepiece magnification at the time of photographing, the objective lens magnification, the light source of the microscope, the identification number of the subject, whether the subject is stained, what the staining material is, or the time after the start of the experiment can be considered. Conventionally, these have been recorded as information by a method such as taking notes when the user takes a picture. In addition, a certain type of recording device for a microscope is configured to record information by automatically imprinting data at a predetermined position in a film to be photographed.

[Problems to be solved by the invention]

In the conventional technique as described above, in the method of taking a picture while taking a memo, the user has to take the memo one by one, which is troublesome. In addition, since the memo and the film taken are separate, there is the inconvenience that there is a risk that the relationship between the memo and the film will be lost or that the memo may be lost later.

Further, in the conventional technique of the data recording apparatus of the type in which the data is imprinted on the film, when the position at which the data is impressed happens to be an important position for observation, there is a problem that the data itself cannot be used depending on the data. . Further, as the number of types of data increases, there is a disadvantage that unnecessary data for the photograph is imprinted on a photographic print, and furthermore, it is difficult to know which numerical value represents which data.

The present invention has been made in view of the above conventional problems, and a recording apparatus for a microscope that records information without writing data on a photographic print itself and allows a user to easily manage photographs and information. Aim to get.

[Means for solving problems]

In order to solve the above-mentioned problems, in a data recording system, a cartridge having a film and a storage unit can be loaded, and a photographing device that surely records the photographing data in the recording unit every time one frame of the film is photographed. A cartridge can be loaded separately from the device, and a recording device that creates data and records the data in the storage unit is provided.

[Operation] In the above configuration, the film is always stored together with the film or the film cartridge from the time of shooting to the time when the film is developed into a negative, and the information related to the taken photo is held in the cartridge. There is no inconvenience of not knowing the correspondence between information and film.
Further, since the recording can be performed in the recording unit separately from the photographing device, the information can be appropriately written in the cartridge taken out from the photographing device.

〔Example〕

FIG. 2 is an external view of a recording apparatus for a microscope according to an embodiment of the present invention. Reference numeral 1 is a table on which a subject is placed, 2 is a light source, 3 is an eyepiece lens, 4 is a focusing dial, 5 is a photographing lens, and 6 is a photographing device. The user adjusts the focus by adjusting the dial 4 while observing the image from the eyepiece lens 3.
FIG. 4 is a top view of the photographing device 6 in a state where the rear pig is opened. Reference numeral 7 is a film cartridge in which a general silver salt film is incorporated. A ROM (not shown) is built in the film cartridge. ROM can write and read information. Input / output of information to / from the ROM is performed via five terminals 8 provided on the surface of the film cartridge 7. The back lid 14 of the image pickup device 6 is provided with five terminals 9 for information input / output. These can be input / output of information by connecting to the five terminals 8 on the film cartridge 7 when the back lid 14 is closed.

FIG. 1 shows a processing procedure of a photograph taken by the recording apparatus of this embodiment. The procedure of processing a photograph will be described below according to the flow of FIG.

At S1, the user obtains an unused film cartridge 7. Although not used, the internal ROM has already written the unique information of the film in the cartridge. The information includes the film ISO speed, the number of film frames, color and monochrome film identification data, and the like.

In S2, the user sets the film cartridge 7 on the photographing device 6. The back lid is closed to enable photographing, and the terminals 8 on the film cartridge 7 and the terminals 9 in the photographing device 6 come into contact with each other to enable information input / output. At this time, the photographing device 6 reads information such as ISO sensitivity from the film cartridge. The read information is used for photographing control in the photographing device 6. For example, the ISO sensitivity information is used to determine the exposure value during shooting.

Further, when the film is loaded, the information is read and the information is written. The information input here is information relating to the photographing device 6, and is information that affects the post-processing of the film or is desired to be recorded. Specifically, whether or not the image capturing device 6 has a half size,
There are information such as whether or not sensitized photography, pre-winding method, identification number of the photographing device 6 and film loading date.

In S3, the user focuses the image by operating the dial 4 while observing the image from the eyepiece lens 3, and then inputs necessary information to the imaging device 6 and then takes an image using the imaging device 6. . FIG. 3 is an enlarged view of a part of the bottom of the recording apparatus for a microscope shown in FIG.
(The same number indicates the same member.) 12 is a keyboard for inputting information. After focusing while looking at the eyepiece 3, the user uses the keyboard 12 to input information. The information entered from the keyboard 12 is
Signal lines prepared inside the members 10 and 13 (not shown)
Is sent to the photographing device 6 via. The information sent to the photographing device 6 is written in the ROM in the film cartridge 7 through the five terminals 9 provided on the back lid 14 and the five terminals 8 on the film cartridge 7. Thereafter, the user operates the shutter release member 15 of the image taking device 6 to take an image equivalent to that observed with the eyepiece lens 3 with the image taking device 6.

The information set by the keyboard may be written in the ROM for each shooting frame in association with the exposure of one film frame by the shooting device or the winding of one film frame.

By the above operation, the user can operate the film cartridge 7
1 frame and 1 image taken on film in the internal ROM
Information corresponding to one-to-one can be left. In addition, since the information is written inside the film cartridge itself, there is no risk of loss. Furthermore, if the user operates the release member 15 without operating the keyboard 12, the release is disabled, and a function to warn the user of forgetting to enter information, or conversely after operating the keyboard 12 once to complete information entry When the keyboard 12 is operated again before the release member 15 is operated, a function of outputting some warning display on the display element 16 is provided so that the information input is always performed once for each frame. It goes without saying that it is configured so that it does not exist. The keyboard 12 also includes a key having a correction function. When an error is found in the input information, the correction key can be pressed to re-input the information before photographing. (The input information is displayed on the display device 17 composed of LCD etc. until the shooting is completed, and the contents can be confirmed by this.) Considered as information written in ROM for each frame at the time of shooting What is given is information that may change for each frame. Specifically, the magnification of the objective lens, the magnification of the eyepiece (imaging) lens, the name and identification number of the subject, the type of processing such as staining and cutting performed to prepare the subject, and the light source of the microscope. The type, temperature, humidity, elapsed time after the start of the observation experiment, date, etc. can be considered. Further, there are designation of the presence or absence of the trimming process, the number of prints, and the print size. For information that can be automatically measured on the recording device side, such as date, temperature, humidity, and time, it is possible to automatically send data to the ROM in the cartridge at the time of shooting by selecting the automatic mode. For information that must be manually input, the information input in the previous frame is displayed on the display element 17, so that only the information that has changed can be set again. If the input of frame information is completed, the time and effort of the user can be further reduced.

When the photographing of one film is completed, the user takes out the film cartridge 7 from the photographing device 6. This may be sent to the lab as it is for requesting the development enlargement process, but usually it is checked by the information converter in the ROM, the contents of the ROM are checked, changed, or added. This is the step of S4. FIG. 5 shows an embodiment of the information conversion device in ROM.

The converter 18 is connected to the terminal 8 on the film cartridge 7. In the figure, only three terminals are shown. Converter 18
There is a keyboard 19 and a display unit 20 on the top. The information in the ROM is displayed on the display unit 20 by operating the keyboard 19. From the display, the contents of the ROM can be confirmed and desired information can be corrected by operating the keyboard 19. For example, at the time of shooting, the number of prints input for each frame, the print size, trimming processing, etc. can be corrected later. You can also add or modify information about the processing of one film. For example, the output form of the finished print can be designated.
The output format is the same service size photo,
What to do with the order of prints when outputting several prints on one large photographic paper, or when outputting three frames for each film?
It is specified such as arranging with 3 pieces of frame ... or sorting and outputting one set at a time).

The film cartridge 7 whose information has been confirmed, added, and corrected in S4 is submitted to the laboratory in S5. S6 and S7 are processed in the lab. In S6, the film cartridge 7 submitted to the laboratory is subjected to film development processing. It is assumed that a large number of film cartridges photographed in the same manner as the film cartridge 7 photographed by the user are gathered in the laboratory. Prior to the development process, each of these film cartridges is applied to the ROM internal information converter 18 of FIG.
Read the processing conditions of the film. In other words, whether it is a black-and-white film or a color film, whether the screen size is half size, whether sensitized development is necessary, whether special print is designated, and the like. Based on these information in the lab,
Judge optimal development conditions, write development time, developer temperature, developer processing, etc. in ROM and classify films by processing type. After that, actual development processing is executed.
It goes without saying that the efficiency of the development processing in the laboratory is higher if there are many of the same processings. Therefore, the ability to classify the processing prior to the development processing is very advantageous for improving the efficiency of the development processing. Also, since the information that the film cartridge has from the beginning is printed on the surface of the cartridge, it can be visually confirmed in the lab.
Information added by the user after photographing (for example, information about half size or need for sensitized development) cannot be visually confirmed. Requests for these processes were conventionally identified by a memo attached by the user when submitting the cartridge to the lab, but with this, the correspondence between the memo and the film cartridge could not be understood during the process in the lab, There is a high risk of accidentally performing different processing. As in this example
Once written in the ROM, the information is always integrated with the film cartridge, eliminating the risk of erroneous processing as described above.

Film cartridges that have been classified as film pre-development processing and in which processing conditions have been written proceed to development processing. FIG. 6 (1) shows one embodiment of the film development processing apparatus of this embodiment. 20 is a film cartridge case in which the pre-processed film cartridge 7 is loaded. 20 after loading
The upper surface of is shielded from light by the light shielding pig 40. Further, five terminals are provided on the inner wall of 20 at positions corresponding to the terminals 8 of the film cartridge 7. The ROM information in the film cartridge 7 is read out via this terminal and sent to the controller 22. A keyboard 24 and a display unit 25 are provided on the controller 22, and the development processing conditions written in the pre-processing are displayed on the display unit 25 for confirmation and the development processing is started. A slit 41 for feeding the film from the 20 side to the 21 side is provided on the connection surface between the 20 and the developing tank 21. When the developing process is started, first, the film is sent to the 21 side through the slit 41 and wound on the reel 26 in the developing tank 21. After that, the slit 41 is blocked by a member (not shown). Next liquid injection port
From 23, inject the developer that meets the conditions confirmed on the display section 25, and after the development time confirmed on the display section 25 elapses, the development tank 21
The liquid is discharged from the bottom discharge port (not shown). After that, the liquid injection and the liquid discharge are sequentially repeated in accordance with a normal film development processing procedure. Film cartridge 7 at the pretreatment stage
If you write all the process steps and time settings in the ROM of, by reading all the above information with the controller 22,
It is also possible to automatically perform the process of injecting and discharging the processing liquid. After development processing, cartridge case 20, development tank 21
Remove the film from the film, hang it with the film cartridge on top, and dry. (Shown in FIG. 6 (2).)
When the drying is completed, the film is rewound into the cartridge by using the motor 42 and stored again, thereby completing the film developing process. (Shown in FIG. 6 (3)) Next, the print process of S7 is executed. FIG. 7 shows an example of the stretching device according to this embodiment. A printing paper is set at a predetermined position on the member 30 and light from the light source 31 is projected for a predetermined time. As a result, the negative image set at that time is projected via the enlargement lens 32 onto the photographic paper placed on 30. 37 is a case for accommodating a negative containing a cartridge, and 38 is a shaft for winding the drawn negative. At the position facing the terminal 8 on the cartridge 7 on the inner wall of the case 37, a terminal for reading or writing the contents of the ROM is provided for each. FIG. 8 shows an enlarged view of the cartridge portion. These are connected to the controller 34, and by operating the keyboard 35, the information in the ROM in the film cartridge is read out and displayed on the display unit 36, or conversely, the information is written in the ROM. Further, the size of the print is determined by operating the dial 33 to change the distance between the lens 32 and the member 30 for stretching.

Next, the operation procedure of this apparatus will be described. First, the developed film cartridge 7 is loaded into the case 37. Next, operate the keyboard 35 to read the ROM in the film cartridge 7.
The information is read out to the controller 34. The information to be read out includes information for one film and information for each frame. The former includes, for example, the number of films and other special notes at the time of development processing, and the latter includes the enlargement size of the frame, the number of enlargements, the presence / absence of trimming, and the user's preference for color (shading and color balance correction). Designation etc.) is considered. After reading the information, the color tone of the negative is confirmed and the printing conditions are determined. The printing conditions are the exposure time,
Color balance correction presence / absence, color shading correction, type of printing paper used, and the like. These printing conditions are written in the ROM in the film cartridge 7 by operating the keyboard 35. After that, the print is actually made by exposing the print paper. If the user has specified in the ROM that specific photographing information should be written on the print, the enlargement device executes the processing. For example, if there is a designation to “write the shooting magnification to the right corner of the print”, the controller 34
It suffices to imprint the information of the photographing magnification read in step 3 at the same time as exposure. Here, the example of the enlargement apparatus has been described as a general example of the print processing, but, for example, if the information read out before the developing processing of S6 is solid printing, a similar embodiment can be considered in the solid printing apparatus. However, a similar embodiment is conceivable in a printing apparatus that requires other special processing.

Through the above processing procedure, the user can obtain the negative containing the print and the film cartridge. The entire process from taking a picture with the recording device for the microscope to making a print in the lab is stored in the ROM in the film cartridge as information, so this information is effective even when requesting another print. Is. Also, when a request for reprinting is received in the lab, it is easy to produce prints under the same conditions as the previous time.

Although the ROM is provided in the film cartridge in the embodiment, it may be provided in the film itself in the cartridge.

〔The invention's effect〕

As described above, according to the present invention, all the information about the film or the negative in the film cartridge can be stored in the film or the film cartridge, so that the information is lost when it is needed later. There is an advantage that such a risk is eliminated. In addition, since the information can be taken into a part other than the film screen, there is an advantage that it is possible to prevent the screen of the photograph from being obstructed by the information. In addition, even though a large amount of information is recorded, there is little danger of information being mixed. further,
Since a recording device capable of recording information in the information storage unit or correcting the information recorded by the photographing device is provided separately from the photographing device, it is possible to appropriately record information in the cartridge after the photographing operation and after the information recording. Alternatively, modifications can be made. Therefore, it is possible to solve the problem that the information cannot be recorded or the recorded information cannot be corrected unless the apparatus is a photographing device, and a user-friendly information recording system can be obtained.

In addition, since it is configured to record information related to film processing, it is possible to perform processing based on the recorded information when performing development processing and print processing that are indispensable for reproducing captured images. The reproduction process can be performed simply.
