Abstract

PURPOSE:To accurately detect a specific picture area and to correctly read the area by arranging a title reading sensor in parallel to an original transfer direction and moving the title reading sensor in an orthogonal direction to the transfer direction when a mark is longer in the orthogonal direction to the original transfer direction. CONSTITUTION:An L-shaped mark (e) along the two orthogonal sides of a title (a) is attached to an original 24, the position of the title (a) is discriminated from the moving position of the original 24 and the position of the element of a position detecting sensor 34 to detect the mark (e), and when it is judged that this title (a) is longer in the orthogonal direction to the original transfer direction, a title reading sensor 36 is arranged to be parallel to the original transfer direction and moved in the orthogonal direction to the original transfer direction. Only the area of this title (a) is read by the title reading sensor 36 in this manner. Thus, the specific picture area such as a title can be detected and recorded accurately, and the device can also correspond to a case in which the dimension of an original is changed.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention records image information and separately records a specific area such as a title part in this image, and uses a list of this specific area to perform recording. The present invention relates to an image information recording/retrieval device that searches for desired information from image information.

(Technical Background of the Invention) There have conventionally been filing devices that use microfilm to record and file books, literature, etc. as images. Devices that record and file this type of image information have a problem in that it is troublesome to search for the desired information. In other words, recorded files are sequentially read out to find the desired information, but in this case, the search takes a lot of time, and when recording the information, the title etc. must be separately extracted. It is possible to prepare your own list by writing it down, but in this case it takes time to create the list.

Therefore, the present application proposes that only a specific image area such as the title be extracted and recorded separately together with the search code, a list of the title etc. and the search code may be outputted as appropriate, and the search code of the desired manuscript may be obtained from this list. considered by people. In this case, since the position of the title etc. differs depending on the document, it is necessary to always be able to accurately read out a specific area such as the title.

(Objective of the Invention) The present invention was made in view of the above circumstances, and when a title list is created by extracting only a specific area such as the title of a manuscript and separately recording this specific area along with a search code, An object of the present invention is to provide an image information recording/retrieval device that can accurately detect a specific image area such as a title and read it correctly.

(Structure of the Invention) According to the present invention, the object is to record the entire manuscript and specific image areas separately, to output a list of specific image areas together with the search code of each manuscript, and to make it possible to output a list of specific image areas together with a search code for each manuscript. In an image information recording/retrieval device that searches for a desired manuscript using a search code, the image extraction means for extracting the specific image area detects a mark that is attached to the manuscript in advance and indicates a specific image area. a detection sensor; and a title reading sensor that reads out the specific image area based on the position data of the position detection sensor; This is achieved by an image information recording Φ retrieval device characterized in that when the mark is long in the direction perpendicular to the document transport direction, the title reading sensor is arranged parallel to the document transport direction and is moved in the direction perpendicular to the document transport direction. be done.

A specific image area such as a title portion in the document 24 is read out by an image extracting means comprising a position detection sensor 34 and a title reading sensor 36. That is, a mark indicating a specific image area such as a title portion is attached to the document 24 in advance, and position data such as the title is obtained by detecting this mark with the position detection sensor 34. For example, a mark is attached with a marker pen or the like of a specific color, and the position detection sensor 34 can selectively detect only this mark by reading the document 24 through a filter that selectively transmits only the color of this mark. The position of can be determined. In FIG. 1, 40 is a CPU, 42 is an input interface, 44 is an output interface, 46 is a ROM that stores control programs, etc., and 48 is a RAM. The CPU 40 moves a specific image area marked with a title or the like to the position of the title reading sensor 36 based on the output of an encoder 39 that generates pulses synchronized with the rotational speed of the feeder motor 38 and the output of the position detection sensor 34. Calculates the timing and outputs the timing to be read. Image data of only the image area read by the title reading sensor 36 (
(referred to as title data) is temporarily stored in the RAM 48. When the original 24 enters the original reading position on the glass plate 20 and the entire original 24 is read into the cassette 26, the CPU 40- detects the original from the output of the encoder 51 attached to the motor 50 that feeds the recording medium of the cassette 26. 24 is recorded on the film stored in the cassette, and a search code is obtained from this address data. Address data can be obtained not only in this case but also by known methods of determining address data that know the recording position of image information, such as by determining the count value from a grip mark detection sensor (not shown) provided on the microfilm. be able to. Further, this search code is stored in the RAM 48 together with the title data. At this time, the date and time when the document 24 was recorded, the user's name (code), etc. may be simultaneously memorized using the keyboard 14 provided in the control section. The title data, search code, and other data stored in the RAM 48 in this manner are transferred to other external memory devices 52 such as magnetic disks, floppy disks, magnetic tapes, magnetic cards, optical disks, optical cards, etc. as appropriate.

The data (title data, search code, etc.) transferred to the external memory device 52 such as a magnetic disk is transferred to the RAM 48 all at once when this device starts to be used, and after new data is additionally recorded in the RAM 48. , is recorded again in the external memory device 52 when the use is finished.
