Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a printing position display method in an information processing system such as a document creation device.

[Background of the invention]

Generally, in a document creation device or the like, a document is edited and created based on document data input using a keyboard, and the document is displayed on a display device C (hereinafter referred to as a CRT). The operator confirms the document displayed on the ORT, prints the document, and is excited.

In such a document creation device, when printing a document on paper, conventionally, the printing position on the actual paper cannot be known from the ORT display. Therefore, when it is desired to set the print position, for example, a method is used in which a preprinted base paper is copied and a test print is performed on the copy paper to adjust the print position. In such a method of performing trial printing, it is extremely difficult to align the printing position in one go.

'Furthermore, in a document creation device, the format (print format) is usually specified before document creation, so the operator knows in advance the printing pitch, line feed pitch, etc. when printing the name book. Accordingly, when inserting and printing characters into an existing document, a method is used in which an operator calculates the current cursor position on the ORT to determine the desired print position. However, such a method requires the operator to calculate the print position from the cursor position, which has the disadvantage of placing a large operational burden on the operator.

[Purpose of the invention]

This invention was made in view of the above circumstances, and its purpose is to automatically change the printing position from the current cursor position on the CRT when printing characters by inserting them into an existing document in a document creation device, etc. It is an object of the present invention to provide a printing position display method that allows a predetermined printing position to be always set reliably and easily by calculating the printing position and displaying it on the ORT.

[Key points of the invention]

This invention converts the cursor position on 01'LT to a print position on printing paper. Information about the print position corresponding to this converted cursor position is displayed on the ORT. This allows the comparison between the current cursor position and print format to be confirmed on the CRT when creating a document.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a partial configuration of a display device of a document creation device according to the present invention. In the figure, 1 is ORT
The controller performs display control when display data VD sent from a CPU (not shown) via the data bus 2 is set to 0RT (not shown) as a display source. The ORT controller 1 includes a register 1a that stores an address X indicating the cursor position sent from the OPU via the address bus 3. 4 is an address selector which selects the address corresponding to the display data sent from the OPU via the address bus 3 and the rask address K from the CRT controller 1.
Both A are given. This address selector 4 is O
Both of the above addresses are selected and output to the refresh memory 5 at the timing of the control signal (read/write control signal) l'tW from the RT controller 1. The refresh memory 5 stores the display data VD sent via the data bus 2 based on the address from the address selector 4, and further outputs the stored display data VD. The storage contents of the refresh memory 5 and the display data displayed on the CRT have a one-to-one correspondence. Refresh memory 5 under the control of ORT controller 1
The display data VD read out is sent to the data selector 7 via the latch circuit 6. The data selector 7 is supplied with print position data PD output from a print adhesion memory (hereinafter simply referred to as memory) 20, and selects data VD, PD according to a select signal S from an AND circuit 8.
Select and output 10,000. The AND circuit 8 receives a print position display command (print position display command corresponding to the cursor position) PI from the CRT controller 1 to the -10,000 input terminal. Further, the output signal G1 of the AND circuit 21 is applied to the other input terminal. The character generator 9 outputs a dot pattern corresponding to the data (character code) output from the data selector 7. This dot pattern is converted into serial data by a parallel/serial conversion register (P/8 conversion register) 10 and sent to a video control circuit 11. The operation of the P/S conversion register 10 is controlled by a control signal M output from the ORT controller 1. The video control circuit 11 has P
0R according to the data output from the /S conversion register 10.
The display is controlled so that T (not shown) is displayed.

10,000, in this invention, the cursor address X stored in the register 1a of the 0TLT controller 1 is
It is applied to a divider 22 which is an arithmetic circuit of U. The quotient Q and the removal R, which are the calculation results of the divider 22, are calculated by each arithmetic unit 23.
．． 24 respectively. The calculation results PD of the computing units 23 and 24 are latched by the latch circuit 25, and then stored in the memory (print position memory) 20.

That is, the calculation result PD is print position data obtained by converting the cursor position to a print position on the print paper. memory 2o
Data PD is written and read in accordance with address PA output from AND circuit 26. The AND circuit 26 is gate-controlled by the output signal G1 of the AND circuit 21, and controls address transfer output from the address selector 4. The AND circuit 21 has one input terminal supplied with the output signal E1 of the comparator 27, and the other input terminal supplied with the output signal B2 of the comparator 28. Comparator 27
is given an address (i.e., an address indicating the position of the ORT screen per character) to the -10 input terminal, and an address (i.e., the print position) from the ORT controller 1 to the other input terminal. An address (B) indicating the first position when displaying the data PD is given. In the comparator 28, the above-mentioned address A is given to the -10,000 input terminal, and the address (i.e., the last position when displaying the print position data PD) is given from the CRT controller 1 to the other input terminal. address) 0 is given.

In addition, 12 is a control bus, and in the normal case, ORT
A side splitting signal and display data from the CIPU are sent to the controller 1.

In such a configuration, the operation according to the present invention will be explained. Normally, the display data VD sent from the CPU is stored in the refresh memory 5 under the control (timing) of the CRT controller. The ORT controller refreshes the display data VD in the refresh memory 5
The data will be controlled to be transferred to the primary CRT.

Accordingly, the display data VD is displayed at 0TtT.

In this case, the OPU will send the current cursor position (ie address X) to the ORT controller. The OR1 controller stores address X indicating the cursor position in register a.

And the ORT controller is a register! The address X in I is output to the divider 22 of the OPU, for example. This divider 22 performs arithmetic processing such as /rX4=80j, for example. At this time,
"80" means, for example, a line of 80 characters on a printing paper. The divider 22 sends the quotient Q, which is the calculation result, to the calculator 23.
It also outputs the removal R to the arithmetic unit 24. The arithmetic unit 23 performs arithmetic processing of, for example, rQ X b + y 6 J. In the arithmetic unit 24, for example, rR
The arithmetic processing of Xa+xoJ will be performed. here,
As shown in Fig. 3, a and b are the pitches (for example, a) of the printed characters in the column and row directions, respectively, and x
O*Y6 is the distance from the left edge of the printing paper to the print start character (in units of [), and the distance from the top edge thereof to the print start character (in units of α). In this way, the computing units 23 and 24 eventually convert the cursor position (address X) into data PD indicating the printing position on the printing paper, and output it to the latch circuit 25. This printing position data PD is stored in the y-edge 2o according to the address PA. This address PA is output from the address selector 4 and is output from the refresh memory 5 which stores the display data VD.
It is the same as the address for .

By the way, the AND circuit 26 outputs the rear address PA in response to the control signal G. This signal G1 is output from the AND circuit 2 when both the signals El and E2 are "1". In this case, the address selector 4 outputs the above address and the above address B (address on the screen shown as 30 in FIG. 2) is [A) BJ, and the address and the above address C (in FIG. When the address on the screen indicated by 31 satisfies both conditions of ``Person<OJ'', both signals EJ and B2 become ``1''. The print position data PD is then sent from the memory 2o to the data selector 7. This data selector 7 has an AND circuit 8
The data PD is selected according to the select signal 8 and outputted to the character generator 9.

Below, normal display control for 0FLT is performed.

In this case, the select signal S is outputted in response to the signal PI output from the 01'LT controller 1 by the operator operating a specific function key (for insert printing) on the keyboard, for example. become.

In this manner, in the present invention, the position of the cursor 32 as shown in FIG. 2, for example, is converted into printing position data P on the printing paper (FIG. 3).

(2) The data p-+ can be displayed on a portion 33 on the screen. In this case, a portion 33 on the screen is a portion that normally displays pages, lines, etc. necessary for document creation. On the other hand, for example, when the operator operates a specific function key as described above, the display of pages, lines, etc. is converted to the display at the cursor position. In Figure 2, at 33 on the screen, the cursor 3
Position 2 is on the printing paper and the distance from the left edge of the paper is 6 (17
1 and the distance from the top of the paper is 60 my*.

In the above embodiment, for example, a case was described in which OR and T are used to display a document page by page. The corresponding position can be displayed.

〔Effect of the invention〕

1. As detailed above, according to the present invention, in a document creation device, etc., the printing position on the printing paper is automatically calculated with respect to the current cursor position displayed on the screen of the ORT, and the printing position on the CRT is automatically calculated. It can be displayed on the screen. Therefore, when printing characters by inserting them into an existing document, the printing position can be easily confirmed from the cursor position by key operation, so that the inserted characters can be printed reliably and easily. This makes it possible to reduce the burden on the operator in document preparation, and also to save on printing paper since trial printing and the like are no longer necessary. That is,
According to the present invention, it is possible to obtain the effect that the efficiency of document creation can be greatly improved.
