JPS6175960A - Retrieving method for index frame of microfishe - Google Patents

Abstract

PURPOSE:To retrieve automatically an index frame with an optional frame position and an optional number of frames, by supplying the data on the format and the position of the index frame to a positioning device for microfishe. CONSTITUTION:A format code FC is supplied to a data table 12 through a format designating device 10. At the same time, the position of an index frame is designated by an index frame designating device 11. Then an index frame code IFC is supplied to the table 12. The table 12 combines these codes and delivers the frame position signals X1 and Y1, and these signals are stored in a memory 13. When an operator operates an index key 15, the position data X1 and Y1 are read out of the memory 13 via a fate 14 and supplied to a positioning device 16. The position of the indicated index frame of the microfishe 2 is shifted to the position of a prescribed optical system. Then the index frame is retrieved automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a method for searching an index frame in a microfiche film.

(Technical background of the invention and its problems) Projecting frame images of microfiche film (hereinafter referred to simply as microfiche) onto a screen,
The configuration of a microfilm retrieval device for making copies is as shown in Figure 1. Light from a light source 1 is irradiated onto a microfiche 2, and the transmitted light from the microfiche 2 is transmitted through a lens system 3. After passing through slit 4
After that, the photosensitive drum 5 for copying is exposed to slit light, and one frame of the image on the microfiche 2 is exposed to the photosensitive drum 5. At the same time, the photosensitive drum 5 and the recording paper 6 are rotated and moved in synchronization in the direction of the arrow shown in the figure. By doing so, the image on the microfilm 2 is copied onto the recording paper 6. Further, a rotatable mirror 7 is disposed below the lens system 3, and by rotating the mirror 7 and placing it in the optical path as shown by the broken line in the figure, the light from the lens system 3 can be removed. The image information of the microfiche 2 is projected onto the screen 8.

Here, as shown in FIG. 2, the microfiche 2 has a mounting part 21 made of a metal piece for transportation and holding, and a transparent jacket is connected to this mounting part 21, and the microfiche is placed in it. It is meant to be inserted. The microfiche is photographed by arranging frames 122, and the number of frames that can be photographed on one microfiche differs depending on the format of the microfiche. It has become commonplace. One of the frame images of Microfiche 2 has an index frame defined to display the information captured on the entire frame, whereas with normal fish film, the frames from left to 22A is designated as the index frame, and COM (Computer Output Micro
of film), the lower right frame 22B is often designated as the index frame, and furthermore, as a user of micro film 2, the frame 22B in the lower right is

The index frames 23A, 24A, and 25A are photographed, and the microfiche 24 is further photographed with its own index frame 24B, and the microfiche 25 is also photographed with its own index frame 24B.
I try to shoot 5B.

Therefore, when specifying multiple index frames like this, the index frame may not always be at a predetermined position such as the upper left or lower right.
The method of searching this index frame has been a problem.

(Object of the invention) This invention was made under the above circumstances,
The purpose of this is to use any frame of the microfinish as an index frame, and also to use any number of frames as an index frame, and to make it possible to search all index frames correctly even in such cases. The purpose is to provide a method.

(Summary of the Invention) This invention relates to a method for searching index frames in microfiche.

The index frame can be automatically created by using an arbitrary frame position and an arbitrary number of frames on the microfiche as an index frame, and inputting the position data of the microfiche formant and index frame into the microfiche positioning device. This allows for a specific search.

(Embodiment of the Invention) FIG. 4 shows an example of a device for realizing the method of the present invention, which includes a formant specifying device 10 for specifying the formant of the microfiche 2 to be searched by inputting a key or the like; An index frame designation device 11 consisting of a key or the like that designates an index frame by designating its XY address when an arbitrary frame position and number of frames on microfiche is designated as an index frame, and a format designation device 10 The data table 12 inputs the format code FC from the format 2 and the index frame code IFG from the index frame designation bag all, and outputs the XY data X1 and Yl of the microfinish 2 in a predetermined combination. a memory 13 for storing XY data, and an index key 15 for supplying the output data from the memory 13 to the positioning device IB via a gate 14.
and a drive device 17 that transports and drives the microfinches 2 using the output of the positioning device IB. The frame position of the microfiche 2 is designated by a horizontal position address X and a vertical position address Y as shown in FIG. In this case, the origin (1, 1) can be arbitrarily determined.

In such a configuration, the formant specifying device 10 inputs a predetermined format using a key, inputs the format code FC as an address signal to the data table 12, and also inputs the position of the index frame for the predetermined format. is specified by the index frame specifying device 11 according to the number,
The index frame code IFC from the index frame specifying device 11 is inputted to the data table 12 as an address signal.

The data table 12 sequentially outputs frame position signals XI and Yl corresponding to each pre-registered format and frame position using a combination of the format code FC and the index frame code IFC, and stores them in the memory 13. It has become. When the data of all the index frames are stored in the memory 13, the operator operates the index key 15 to
Position data x is sequentially transmitted from the memory 13 through the gate 14
1 and Yl are read out and input to the positioning device IB,
The positioning device 16 drives the motor 17 according to the XY position data XI and Yl to move the microfish 2 to the position of the index frame designated by the format designation device 10 and the index frame designation device 11 to a predetermined optical system position. You can search by going to .

(Effects of the Invention) As described above, according to the search method of the present invention, even if an arbitrary frame position and an arbitrary number of frames on microfiche are used as an index frame, positioning can be performed freely by specifying the format and specifying the index frame. Therefore, the efficiency of microfiche retrieval can be increased.
