Description

[Detailed Description of the Invention] This invention relates to a jacket for microfissuring which holds a microfissuring film in a packaging portion.

The developed film has a spectral characteristic of transmittance with respect to the wavelength of light.If we take the transmittance (%) on the vertical axis and the wavelength (nm) on the horizontal axis, the silver halide photographic film will have the spectral characteristics of A in Figure 1. As shown in the figure, it has almost flat spectral characteristics; diazo film (blue) has a curved spectral characteristic as shown in figure B, and diazo film (black) has a spectral characteristic as shown in figure C. It has characteristics. In addition, the spectral characteristics of the lamp used for film exposure are as shown in curve D in Figure 1 at 3300K, for example, when the vertical axis is the light intensity (Lux) and the horizontal axis is the wavelength (nm). ing. Therefore, when reading an image on a film, it is not possible to obtain a high-quality image unless the spectral characteristics of these films are taken into consideration.

By the way, the microfilm includes a roll film in which images are taken in the length direction, and a roll film in which images are taken in the length direction, and a
There is a rectangular sheet film obtained by photographing a plurality of images 2 arranged vertically and horizontally as shown in FIG. Here, regarding the former roll film, there are cases where it is stored in a cartridge as a long film and cases where it is used, for example,
As disclosed in Japanese Patent No. 118720, a roll film is cut to a predetermined length and stored in a so-called jacket consisting of a transparent base and a cover member forming a packaging part, and the latter is used for microfissuring. There are cases where it is used in a form similar to 1. When the image 2 of the microfissure 1 is to be copied using a microreader printer or the like, or to be scanned and read by a line sensor and sent electronically, the microfissure 1 must be copied as shown in FIG. Irradiated by a lamp 3, the transmitted light of the microfissure 1 is transmitted through a lens system 4 to a line sensor 5.
to scan in a line to read the entire screen. In this case, as mentioned above, the photosensitive material of the microfissure 1, the lamp 3, etc. have spectral characteristics, and in order to scan and accurately read the image 2 taken by the microfissure 1, these spectral characteristics are necessary. It is necessary to take this into consideration and uniformly scan the entire image. For this reason, conventionally, a filter 6 is provided behind the lens system 4 to compensate for the spectral characteristics of the fish film 1 and the lamp 3, that is, to cut out light in a wavelength range unnecessary for reading the microfiche image held. is inserted, and the line sensor 5 scans and reads the image on the flash film 1 using the spectral characteristics compensated by the filter 6.
Therefore, when the microfuge 1 is replaced or when the spectral characteristics of the lamp 3 change, it is necessary to change the spectral characteristics of the filter 6 accordingly, and a large number of filters 6 must be prepared. The filter 6 with the most suitable spectral characteristics is then replaced each time. Therefore, it is complicated to prepare and manage a large number of filters 6 with different spectral characteristics, and a mechanism for attaching and detaching the filters 6 is required, and furthermore, it takes a lot of time to attach and detach the filters. In short, it has some flaws.

Therefore, it is an object of this invention to provide a jacket for a microfissile that overcomes the above-mentioned drawbacks.

This idea will be explained below.

In this invention, as shown in FIG. 4, the three sides of two rectangular transparent materials (for example, vinyl sheets) 10 and 11 are glued together to form the packaging part 12, and the packaging part 12 is made without a jacket. A microfissure 1 can be inserted into the opening. At the same time, a holding part 13 is extended to one side of the packaging part 12, and a mounting part 14 made of a metal magnetic material such as an iron piece is attached to the end thereof. This mounting section 14 is used to transport the jacket by attracting it with a magnet or the like, or to identify the contents of the microfiche image inside the jacket. Here, the transparent materials 10 and 11 each have spectral characteristics similar to those of the filter 6 described above, and the jackets of the microfissure 1 are classified according to the difference in the spectral characteristics of the transparent materials 10 and 11. There is. That is, for example, when the image of the microfissure 1 attached to the packaging part 12 is diazo film (blue) B shown in FIG. 1, the transparent materials 10 and 11
The spectral characteristics of
Light is transmitted only in the region around 600nm, other regions,
In other words, a material (red material) that cuts out light in a wavelength range that is unnecessary for image reading by the microfissure 1.
is selected to form a jacket, and this jacket is classified for diazofilm (blue) B. Similarly, in the case of diazo film (black) C shown in Figure 1, light with a wavelength range of 650 nm or more (infrared light)
form a jacket using the material to be cut,
This jacket is classified as one for diazo film (black). Note that the total thickness of the jacket is approximately a few minutes thick.
1mm, and the microfissure 1 is inserted into the packaging part 12 from the opening and the fifth
As shown in FIGS. A and B, it is completely inserted and held within the packaging portion 12.

In this way, the microfissure 1 is inserted into the packaging part 12 of the jacket for transportation, storage, lead/reading, etc.
When printing is performed, the spectral characteristics of the microfissure 1 and the exposure lamp 3 are compensated by the spectral characteristics of the transparent materials 10 and 11 of the jacket, so the optical system is equipped with the filter 6 as described above.
There is no need to prepare and use it. Furthermore, by changing the jacket according to the spectral characteristics of the microfish 1, it is possible to always obtain optimal spectral characteristics in accordance with the spectral characteristics of the microfish 1.

In addition, in the above-mentioned embodiment, the shape of the jacket is a wrapping part with three sides glued together, but the transparent material 1
Any structure is sufficient as long as the microfissure 1 can be inserted and held between 0 and 11. Further, the structure of the mounting portion 14 of the jacket may be arbitrary, as long as it is capable of transporting and storing the microfish 1 by inserting and holding the microfish 1 between transparent materials having spectral characteristics.

In addition, the microfilm attached to the jacket is not limited to sheet film, but as mentioned above,
It goes without saying that roll films may be cut into predetermined lengths and inserted in a plurality of rows.

As described above, the microfissile jacket of this invention has spectral characteristics that compensate for the spectral characteristics of the inserted microfissure, so that the microfissile image processing can be performed on the entire jacket. This makes it possible to process without using a filter while compensating for the spectral characteristics.
It is possible to simplify the device and reduce costs.
