Abstract

PURPOSE:To attain efficient document retrieval by storing temporarily the document number of a document during display and displaying again a document corresponding to the document number stored temporarily at any time when other document is displayed. CONSTITUTION:Picture information of plural documents is stored in a document storage section 1 and control information such as its document number is stored in a system processing section 3. At first, when a document display command and the document number of a document desired to be displayed are inputted from an operation command section 2, a system processing section 3 stores its document number and reads the document picture information corresponding to the document number from the document storage section 1 and displays it on a display section 6 via a read/write section 4 and a display control section 5 from the document storage section 1. Then the operation command section 2 gives a command to store temporarily the document number of the document during display in this state and even when other document is inputted and displayed, a document corresponding to the document number stored temporarily as above is displayed at any time.

Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Field of Industrial Application) The present invention provides a method for temporarily storing the document number of the document being displayed in a document display device on which already stored document image information is being displayed; The present invention relates to a document search and display method that makes it possible to display a document corresponding to a temporarily stored document number after displaying another document.

(Prior art) Conventionally, in this type of display method, when displaying a document, the document number or document name is input from the keyboard, or the document name is displayed and the cursor is manually moved to the name of the document. It was moving sideways.

Additionally, some conventional devices are equipped with a dedicated key that instructs to display the document corresponding to the document number next to the document being displayed, or the document corresponding to the document number immediately preceding the document being displayed. There were also some that avoided the complexity of entering document numbers.

(Problems to be Solved by the Invention) In the method of inputting the document number or document name using the keyboard, it is troublesome to enter the document number or the document master's skill. There are drawbacks such as the need to write down the document number or document name on memo paper, etc., and the document number that corresponds to the next document number of the currently displayed document or the document number immediately before the currently displayed document. If you use a method that avoids the hassle of inputting document numbers by providing a dedicated key that instructs the display of the document corresponding to The disadvantage was that the documents had to be searched.

ADVANTAGES OF THE INVENTION (Means for Solving the Problems) In order to solve the problems mentioned in section 2, the present invention provides a means for solving the problems described in ``2''. The document number of a document can be temporarily stored, and the document corresponding to the temporarily stored document number can be displayed at any time while displaying another document.

(Function) According to this display method, for example, the document number of a document that is referred to many times, such as a diagram, can be temporarily stored, and when another document is being displayed, the document can be immediately redisplayed. This makes it possible to perform document searches efficiently.

(Embodiment) FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, in which 1 is a document storage section, 2 is an operation instruction section, 3 is a system processing section, 4 is a read/write section, and 5 is a block diagram showing the configuration of an embodiment of the present invention. A display control section, 6 a display section, and 7 a document number storage section.

In explaining the operation, it is assumed that the image information of a plurality of documents is stored in the document storage section 1, and that the control information such as the document number is stored in the system processing section 3.

First, a document display command and the document number of the document to be displayed are inputted from the operation instruction section 2.

The system processing section 3 stores the document number and controls the document image information corresponding to the document number to be read out from the document storage section 1 and displayed on the display section 6 via the writing section 4 and the display control section 5.

Next, in the "2" state, the operation instruction unit 2 instructs the user to temporarily store the document number of the document being displayed.

FIG. 2 shows the detailed structure of the processing flow in the system processing section 3 and document number storage section 7, in which 10 is a read register, 11 is a write register, 12 is a temporary storage buffer, 13 is a buffer control section, 14 is a write pointer,
15 is a read pointer, 101 is a reset signal line, 10
2 is a write instruction signal line, 103 is a read instruction signal line, 1
04 is a write notification signal line, and 105 is a read notification signal line.

When the system processing unit 3 is instructed by the operation instruction unit 2 to store the document number of the document being displayed on the display unit 6,
The stored document number is stored in the write register H.

At the same time, write pointer 14, read pointer 15
The reset signal line 101 is activated to reset the document number, and the write instruction signal line 102 is activated to store the document number in the temporary storage buffer 12.

Upon receiving the activation signals from the two signal lines, the buffer control unit 13 resets the write pointer 14 and the read pointer 15 (the pointer position is set to the temporary storage buffer 1).
2) and then write register j1
writes the document number stored in the temporary storage buffer 12 at the address indicated by the write pointer 14, advances the write pointer 14 by +1, and then
4 and sends a write notification to the system processing section 3.

When a document display command and the document number of another document to be displayed are input from the operation instruction unit 2, the system processing unit 3 stores the document number and stores the document image information corresponding to the document number in the document storage unit. 1, it is controlled to be displayed on the display section 6 via the read/write section 4 and the display control section 5.

Here, when the operation instruction unit 2 instructs to temporarily store the document number of the document being displayed, the system processing unit 3 writes the document number in the write register 11 and activates the write instruction signal line 102.

When the buffer control unit 13 receives the start signal from the signal line, it writes the document number stored in the write register 11 to the address indicated by the write pointer ]4, then advances the write pointer 14 by +1, and then starts writing. The notification signal line 104 is activated.

After displaying the document and temporarily storing the document number of the document being displayed is repeated in the procedure described in 1. You will be prompted to display the image information for the document you want to print.

The system processing unit 3 activates the read instruction signal line 103,
The specified address of the temporary storage buffer 12 is sent to the buffer control unit 13.

When the buffer control unit 13 receives the activation signal and address on the read instruction signal line 103, it writes the address into the read pointer 15, and subsequently writes the document number stored at the address indicated by the read pointer 15 (i.e., the received address). is read into the read register 10, and the read notification signal line 105 is activated to issue a read notification.

The system processing section 3 reads out the document number stored in the reading register 10, reads out the image information of the document corresponding to the document number from the document storage section 1 through the reading and writing section 4, and reads it out through the display control section 5. Control is performed to display on the display unit 6. At this time, the document image information that was displayed immediately before is erased.

Note that when the write pointer 14 indicates the end of the temporary storage buffer 13 and an instruction is given to temporarily store the document number of the currently displayed document, the buffer controller 13 writes the document number as indicated by the write pointer 14. Write to the location and reset the write pointer 14 to 1. Therefore, the pointer position indicates the beginning position of the temporary storage buffer 12.

In the above description, the user inputs from the operation instruction section 2 when instructing - out of a plurality of document numbers stored in the temporary storage buffer 12. However, the document image information may be read out from the document storage section 1 and displayed using the document number located at the address indicated by the readout pointer 15 without any instruction from the user.

Also, each time a document number is written to the temporary storage buffer 12,
The contents of the read pointer 15 may be advanced by +1. In this case, when the operation instruction section 2 instructs to display the image information of a document with the document number stored in the temporary storage buffer 12, the document image information of the document number stored most recently is displayed. Ru.

As described in detail, in the present invention, the document number of the document being displayed is stored, and after displaying another document, the document corresponding to the stored document number can be displayed at any time. Therefore, when there is a document that is to be displayed many times, such as a diagram, it is possible to omit the trouble of inputting the document number of the document, and there is an advantage that the operation time can be shortened.
