Description

[Detailed Description of the Invention] (Technical Field of the Invention) This invention relates to a format determination gauge for micro-photography film that can easily determine the format of micro-photography film. Regarding film format gauges.

(Technical background of the invention and its problems) Fig. 3 shows an example of a conventionally used micro-flash film 3, which has a title column TL in which the title of the film is recorded in the upper part of the figure. , and below it are the frames P _A1 to P _Ao in the horizontal (row) direction as shown, and the vertical (column) as shown.
It is composed of an image frame field PP in which m frames of m frames from P _A1 to _{P n1} in the direction can be taken, for a total of m×n frames.
This fish film 3 has various formats depending on its frame size, and a format number corresponding to the number of frames is determined. In the example shown in FIG. 3, a total of 14 x 7 = 98 frames, 14 frames in the row and 7 frames in the column, can be photographed, and the format number is "98F" corresponding to the number of frames, 98.

When placing such a film on a reader for automatic search, the reader automatically searches for the desired frame address according to the frame size.To perform an automatic search, first enter the format number above. When you set the frame size, number of frames, etc., and enter the frame you want to search using the frame address specified by the number of columns and row frames from the first frame P11, the reader selects the frame corresponding to this frame address. It automatically detects the location and searches for the desired frame.

Therefore, in order to perform an automatic search as described above, it is necessary to enter the film's format number and the address of the frame to be searched, but the format number is not necessarily written on the film, and the search You can find the address of the frame you want if it is written in an index or the like, but it is often not written there.

To this end, conventionally, an operator has had to count the number of frames taken on the flash film along the rows and columns, calculate the product of the numbers, and select the format number. Also,
After finding this format number, the desired frame address must be found by counting along the rows and columns in the same way, which places a great burden on the operator. In particular, the format number “420F”
For film, etc., a total of 28 x 15 = 420 frames are shot, with 28 frames in the row row and 15 frames in the column.
The counting was a huge burden. Furthermore, depending on the format, the number of frames in the row or column may be the same but the number of frames in the column or row may be different, and the format number cannot be determined by counting only the number of frames in the row or column. Both had to be counted.

(Purpose of the invention) This invention was made in view of the above-mentioned circumstances, and the purpose of this invention was to make it possible to determine the format size visually by simply touching the film, and also to be able to determine the frame address. An object of the present invention is to provide a readable flash film format gauge.

(Summary of the invention) This invention relates to a format determination gauge for a photographic film, which is made of a mount to which the photographic film can be brought into contact, and is capable of determining the frame size and frame pitch photographed in each row and column of the photographic film. All the formats of the fish film are arranged and displayed on the surface of the mount so as to correspond to the rows and columns, respectively, and addresses are displayed on the frames of each row of the rows and columns, making it easy to search. The corresponding format can be determined by abutting the desired file format along the rows and columns on the mount.

(Embodiment of the invention) Fig. 1 shows an embodiment of the film format judgment gauge 1 of this invention, which can be used for each of 10 types of format judgment gauges with format numbers "60F" to "420F" (hereinafter simply "judgment"). 10 (abbreviated as gauge) is displayed on the mount. In FIG. 1, the judgment gauge 10 displays an example of a frame along each row and column for each format in an "L-shape" that shares the first frame of the row and the last frame of the column at full size. Displayed.
In the same figure, the details will be explained by exemplifying the judgment gauge 10 with the format number "60F".The finish with the format number "60F" has an address in its row with a numerical value of "1" to "12". 12 frames are given, and 5 frames are given addresses in the above title field TL and alphabets from "A" to "E" in the columns, and the frame with addresses 1 and E is the bending point of L.
The text is displayed in full size. Each row and column frame is displayed with the same size as the frame pitch of the film, and each frame has a row or column address (“1” to “12”).
or "A" to "E"). Furthermore, in the example shown in FIG. 1, the colors or patterns between the phosphorized frames are changed so that the pitch between the frames displayed on the judgment gauge can be easily distinguished.

To explain a method of determining a flash format and a method of reading an address using a determination gauge having such a configuration, a camera film 3 shown surrounded by a dotted line on the determination gauge 1 shown in FIG. The corresponding frame column PP is each judgment gauge 10
(In the figure, the format number ``98F'' is for the camera film 3.)
(shows the state in which it is in contact with the judgment gauge),
If the positions are sequentially shifted and the format number indicated by the judgment gauge 10 with the matching pitch is read by visual inspection, this number will be the format number of the relevant flash film. Then, in order to read the frame address, use a judgment gauge whose format matches this, and visually read the numerical value and alpha alphabet displayed on each frame of the row and column corresponding to the target frame.
This numerical value and alpha bet represent the address of the frame in question.

Here, this format judgment gauge 1
The arrangement pattern of the determination gauges 10 displayed in is arbitrary, and as shown in FIG. 1, they may be arranged facing each other, or all the gauges may be displayed aligned in the same direction.

FIG. 2 shows another embodiment of this invention, and this flash format judgment gauge 2 includes row formats showing all types of row frame patterns of all formats shown in FIG. Judgment gauges R1 to R8, 21 and column format judgment gauges C1 to C5, 20, which indicate all types of frame patterns in the column, are displayed in full size, and furthermore, the row format judgment gauges R1 to R8 and Format number table 2 showing a list of format numbers that correspond to the combinations of the above column format judgment gauges C1 to C5.
2 is displayed. Here, each frame in this format judgment gauge 2 is also
As illustrated in the figure, the colors or patterns between the phosphorized frames may be changed and displayed. Furthermore, the arrangement of the row format determination gauge 21, column format determination gauge 20, and format number table 22 is arbitrary.

A format determination method and an address reading method using a format determination gauge having such a configuration will be described below with reference to FIG. 2.

A photographic film (not shown) whose format number is to be determined is placed on each row format determination gauge 21 and each column format determination gauge 2.
An example of the row and column of the film is brought into contact with the film, and the matching row format numbers R1 to R8 and column format numbers C1 to C5 are read out by visual inspection. Here, for example, if there is a film whose row frame pitch matches the row format number R3 and whose column frame pitch matches the column format number C2, use the above format number table 22 to determine the row format number R3 and the column format. “84” is displayed in the column where it intersects with matuto number C2.
can be read as the desired format number. When reading a frame address, the address corresponding to the frame can be visually read in the same manner as the row format number and column format number described above.

(Modified example of the invention) In the above embodiment, the color or pattern between each phosphorized frame was changed to make it easier to distinguish between each frame, but if the gauge is such that each frame pitch can be accurately distinguished, each frame may be A line segment indicating the gap may be sufficient. Further, in the above-described embodiment, an example was shown in which all the formats are displayed in the same drawing, but each format may be displayed in a separate drawing.

(Effects of the invention) As described above, according to the film film judgment gauge of this invention, when a film is brought into contact with the film film judgment gauge, the format number assigned to the gauge with the same frame pitch can be read. The format number can be easily read by simply reading it visually, and the target frame address can also be read in the same way.
