Abstract

PURPOSE:To update successively a displayed document, and also to retrieve and display at a high speed a document to be displayed, by providing a prescribed retrieval instructing button on a console, and operating this button. CONSTITUTION:When a button A (or a button B) of a console 1 is depressed, a signal for informing a fact that the button concerned has been depressed is transferred to a main control device 2. The main control device 2 sends out a document page number which is being displayed on a display device 7 at present and +1 when the button A has been depressed (-1 when the button B has been depressed), to an adding circuit 3. The adding circuit 3 adds both numerical values which have been received from the main storage device 2, and returns alpha+1 when the button A has been depressed (or alpha-1 when the button B has been depressed), to the main storage device 2. The main control device 2 confirms whether the button A (or the button B) of the console 1 is being depressed or not, and in case when said button is being depressed, an operation for executing the retrieval and display of the next document page is repeated continuously.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document search and display method for easily and quickly searching and displaying documents in an apparatus for searching and displaying documents.

(Prior art) In the conventional document search display method, by directly inputting the page number of the document to be displayed from the operation instruction console or by pressing the search instruction button once, the document that has been advanced by one page is displayed. The method of doing so was adopted.

(Problem to be Solved by the Invention) When directly inputting the document page number to be displayed from the operation instruction console, it is troublesome to input the document page number, it is necessary to remember the document page number, and it is necessary to press the search instruction button. When displaying a document that advances by one page by pressing the button once, there is a drawback that if you want to skip n pages, you have to press the search button 0 times.

Structure of the Invention (Means for Solving the Problems) In order to eliminate these drawbacks, the present invention provides a system that automatically displays page search one after another when the search button is pressed continuously, and that searches for pages at high speed. If you want to search, you can do so by keeping the high-speed increment or decrement button pressed.

(Function) In this way, it is possible to simplify the operation and enable high-speed search.

(Embodiment) The figure is a block diagram showing the configuration of an embodiment of the present invention, in which 1 is a console, 2 is a main controller, 3 is an addition circuit, 4 is an input/output control circuit, and 5 is a file storage device. , 6 is a display control circuit, 7 is a display device, 10 is a read instruction signal line, 2
0 is a read completion signal line.

The console 1 has the following four types of search instruction buttons.

A button; Slow increment button B button; Slow decrement button C button; Fast increment button; Fast decrement button First, the slow increment operation and slow decrement operation will be explained.

When button A (or button B) on console 1 is pressed, a signal is transmitted to main controller 2 to notify that the button has been pressed. The main control device 2 manages the document page number (for example, α page) currently displayed on the display device 7, and this document number α page.

When the A button is pressed, +1 (or -1 when the B button is pressed) is sent to the addition circuit 3.

The addition circuit 3 adds both numerical values received from the main controller 2, and when the A button is pressed, α+1 (or when the B button is pressed, α−1)
is returned to the main controller 2.

Main control bag [2 is input/output by replacing the next search display page, α+1 when A button is pressed (or α-1 when B button is pressed) with the currently displayed document page number that is being managed. An instruction to search and display the next page is given to the control circuit 4 via the read instruction signal line 10.

The input/output control circuit 4 searches for and reads the next page from the file storage device 5, transmits it to the display control circuit 6, and at the same time notifies the main control device 2 of read completion via the read completion signal line 20. . The display control circuit 6 displays the received document page on the display device 7.

The main controller 2, which has received the read completion notification,
Check whether the button (or B button) is being pressed. [As soon as the search instruction button is stopped being pressed, a signal indicating this is transmitted to the main controller 2.

It is determined whether or not the button is being pressed based on the presence or absence of the signal, and if the button is being pressed, the above-described operation is repeated in order to carry out search and display of the next document page.

If it is not being pressed, the above operation is stopped.

Through the above-described operations, when the A button (or B button) on the console 1 is being pressed, the document is displayed one page at a time.

Next, high-speed increment operation and high-speed decrement operation will be explained.

The operating principle is similar to the slow increment operation and slow decrement operation.

The differences are that in the case of high-speed operation: 1. It is necessary to press the C button (or D button) on the console 1; and 2. The data sent from the main controller 2 to the adder circuit 3. is the page number of the currently displayed document (for example, page α) and 10m when the C button is pressed (or -m when the D button is pressed), and the resulting addition result is α10m. (or α-m) becomes the next document read request page.

From the above, during high-speed increment operation and low-speed decrement operation, high-speed search display can be performed by skipping m pages.

In this case, m is a constant determined and set in advance by the system, but it is also possible for the system to dynamically vary m. For example, if the increment operation is executed a certain number of times or more, the system may automatically replace m with 2m, doubling the search speed.

Furthermore, as explained above, the present invention allows the display of the displayed document to be updated page by page by operating the four types of buttons provided on the operation console. You can also perform a high-speed search display.

Therefore, in the audio graphics teleconference system, when displaying explanatory documents that have been input in advance on a display device and sequentially explaining them, there is no need to specify a page each time.

By using a combination of four types of buttons, search display and explanation can be easily performed.

It is also useful when searching and displaying a specific document from a large amount of documents in a document filing device such as an electronic cabinet. This is particularly effective in document retrieval when the document number to be retrieved is not known.

Claims (1)

[Scope of Claim] A document search and display device that searches a large amount of documents stored in a file storage device and displays them on a display device in response to a search instruction request from a console, comprising: There are four types of search instruction buttons: decrement, high-speed increment, and high-speed decrement. When the low-speed increment button is pressed, 1 is added to the document page (n) that was displayed immediately before searching, and the next page (n+1) is added.
When the slow decrement button is pressed, 1 is subtracted and the next page (n-1) is searched and displayed. When the high speed increment button is pressed, a preset constant m is added and the next page (n+m) is searched and displayed. When the high-speed decrement is pressed, the constant m is subtracted and the next page (n-m) is searched and displayed. When the search display is completed, if the search instruction button is still being pressed, the above operation is repeated. A document search and display method is characterized in that new document pages are continuously searched and displayed one after another.
