It is assumed that the Y coordinate of the mouse cursor 603 is the Y coordinate of the end point, and the display range frame 702 is a rectangle having the same aspect ratio as the aspect ratio of the paper edit screen 601. As a result, the contents of the sheet 801 can be displayed on the sheet editing screen 601 with the same vertical / horizontal enlargement / reduction ratio.

Further, as shown in FIG. 7, it is assumed that the paper layout 701 is displayed on the display range designation screen 602 so that the vertical direction is exactly entered.

First, the mouse information acquisition means 11 receives information on whether or not the mouse input device 1 has been moved and the mouse button has been pressed (step 101).

The display range frame position determining means 12 determines whether or not the mouse button is pressed based on the information received by the mouse information acquisition means 11 (step 102). If the mouse button is pressed, the mouse cursor is pressed. Position M (X _M , Y _M )
Is displayed on the display range designation screen 602 (step 103). If it is not on the display range designation screen 602,
The process ends assuming that the mouse button has been pressed for purposes other than displaying the paper edit screen. If it is on the display range designation screen 602, since the mouse button was pressed to display the paper edit screen, the position M is stored in the start point R ₁ (X _R1 , Y _R1 ) as the start point of the display range frame 702. Yes (Step 10
4). Further, the position M is set to the mouse cursor position M ₀ (X _M0 , Y
It is stored in _M0 ) (step 105).

Subsequently, the mouse information acquisition means 11 receives information on whether the mouse input device 1 has been moved and the mouse button has been pressed (step 106).

The display range frame position determining means 12 determines the position M (X _M , Y _M ) of the mouse cursor 603 from the previous mouse cursor position M ₀ (X _M0 ) based on the information received by the mouse information acquiring means 11. , Y _M0 ) compared to mouse input device 1
It is determined whether or not has moved (step 107).

If the mouse input device 1 has moved,
After the control is passed to the display range frame erasing means 14 and the display range frame 702 currently being displayed is erased (step 117), the mouse cursor position M (X _M , Y _M ) is on the display range designation screen 602. (Step 118),
If it is not on the display range designation screen 602, the process is terminated assuming that the mouse button is pressed for a purpose other than the display of the paper edit screen, and if it is on the display range designation screen 602, the display range frame display means 13 is controlled. The transfer display range frame 702 is displayed (step 119), and the position M is set to the mouse cursor position M.
_It is stored in ₀ (X _M0 , Y _M0 ) (step 120) and the process returns to the process (step 106) of receiving the information on the movement of the mouse input device 1 and whether the button is pressed.

If the mouse input device 1 has not moved, it is determined whether or not the mouse button has been pressed (step 108). If the mouse button is not pressed here, it means that the mouse input device 1 is neither moved nor operated, and therefore the mouse information acquisition means 11
Then, the process returns to the process (step 106) of receiving the information on the movement of the mouse input device 1 and whether the button is pressed.

If the mouse button has been pressed, the mouse cursor position M (X _M , Y _M ) is displayed on the display range designation screen 60.
It is judged whether or not it is above 2 (step 109). If it is not on the display range designation screen 602, it is determined that the mouse button has been pressed for a purpose other than the display of the paper edit screen, and control is passed to the display range frame erasing means 14 to erase the display range frame 702 (step 116). The process ends. If it is on the display range designation screen 602, the starting point R ₁ and the mouse cursor position M
Are not the same (step 110), and either or both of the start point R ₁ and the mouse cursor position M are on the paper layout 701 (step 111), the position M is set as the end point of the display range frame 702 and the end point. The data is stored in R ₂ (X _R2 , Y _R2 ) (step 112). If the starting point R ₁ and the mouse cursor position M are the same (step 110), the starting point R 1
1 and the mouse cursor position M are both the paper layout 701.
If it is not above (step 111), the process returns to the process (step 106) of receiving the information about the movement of the mouse input device 1 and whether the button is pressed by the mouse information acquisition means 11.

The end point R ₂ (X _R2 , Y of the display range frame 702)
_{When R2} ) is determined, control is passed to the display range frame erasing means 14 to erase the display range frame 702 (step 113),
The display range calculation means 15 causes the lower left coordinates D (X _D , Y) of the position to be displayed on the paper from the position of the display range frame 702.
_D ), the display width W _D , and the display height H _D are calculated (step 114), and control is passed to the edit screen display means 16.

The edit screen display means 16 is the external storage device 4.
Display lower left coordinate D (X
_The width W _D height H _D portion is read from _D , Y _D ) and enlarged / reduced so as to fit on the paper editing screen 601, and the lower left of the paper editing screen 601 of the display device 3 is displayed as a reference point. (Step 115).

Next, the processing of the display range frame display means 13 will be described with reference to FIG.

In the display range frame display means 13, first, the mouse cursor position R ₁ (X _R1 , Y _R1 ) when the mouse button is pressed for the first time is set as the display range frame start point F ₁ (X _F1 , Y _F1 ). (Step 201).

Further, the display range frame end point F ₂ (X _F2 ,
The X coordinate of Y _F2 ) is based on the Y coordinate of the mouse cursor position M and the Y coordinate Y of the mouse cursor position M (X _M , Y _M).
A value obtained by multiplying _M by the aspect ratio EX / EY of the paper editing screen 601 is set, and the Y coordinate is set at the mouse cursor position M (X _M ,
The Y coordinate Y _M of Y _M ) is set (step 202).

By using the Y coordinate of the mouse cursor position M as a reference, the display range frame 702 always sets the Y coordinate of the mouse cursor 603 as the Y coordinate of the end point, and the paper editing screen 6
The rectangle has the same aspect ratio as that of 01.

When the display range frame start point F ₁ (X _F1 , Y _F1 ) and the display range frame end point F ₂ (X _F2 , Y _F2 ) are determined,
A rectangular frame with a diagonal line connecting F ₁ and F ₂ is drawn (step 203).

Next, the processing of the display range frame erasing means 14 will be described with reference to FIG.

In the display range frame erasing means 14, first, at present,
It is determined whether the display range frame 702 is being displayed (step 301). If it is not being displayed, the process ends without doing anything. If it is being displayed, the display range frame start point F ₁ (X _F1 ,
Y _F1 ), display range frame end point F ₂ (X _F2 , Y _F2 ), since the start point and end point of the display range frame 702 currently being displayed remain, the line segment connecting F ₁ and F ₂ is a diagonal line. The rectangular frame to be deleted is deleted (step 302).

Next, the processing of the display range calculation means 15 will be described with reference to FIG.
Will be described with reference to.

In the display range calculation means 15, first, the starting point R
₁ (X _R1 , Y _R1 ) and the end point R ₂ (X _R2 , Y _R2 ) are simultaneously compared in X coordinate (step 401). If X _R1 is X _R2
If larger, the values of X _R1 and X _R2 are exchanged (step 402). Similarly, Y coordinates are compared with each other (step 403). If Y _R1 is larger than Y _R2 , Y _R1 Y
The value of _R2 is exchanged (step 404).

Now, without fail, the starting point R ₁ (X _R1 , Y _R1 )
Is the lower left of the display range frame 702, the end point R ₂ (X _R2 , Y _R2 ).
Is the coordinates of the upper right corner of the display range frame 702.

The coordinate value D (X _D , Y _D ) of the starting point R ₁ (X _R1 , Y _R1 ) on the paper 801 is displayed in the display range designation screen 60.
It is determined by multiplying each coordinate value of the starting point R ₁ (X _R 1, Y _R1 ) on 2 on the sheet layout 701 and the size of the sheet 801. Here, since the paper layout 701 is displayed on the display range designation screen 602 so that the vertical direction is exactly entered, the vertical direction ratio PY /
Multiply by WY (step 405).

Further, the width W _D' of the display range on the sheet 801
The height H _D is calculated by multiplying the magnitude ratio of the width X _R2 -X _R1, and the height Y _R2 -Y _R1 to the sheet layout 701 and the sheet 801 of the display range frame 702 on the display range specifying screen 602 To be Here, since the paper layout 701 is displayed on the display range designation screen 602 so that the vertical direction fits exactly, the vertical direction ratio PY / WY is set with reference to the vertical direction.
Is multiplied by (step 406).

Further, as shown in FIG. 9, a display range frame 70
When selecting the end point of 2, the display range frame 702 always uses the X coordinate of the mouse circler 603 as the X coordinate of the end point, and the display range frame 702 is a rectangle having the same aspect ratio as the aspect ratio of the paper editing screen 501. 10 shows the processing of the display range frame display means 13 with reference to the X coordinate method at the mouse cursor position M.
It may be replaced with the processing shown in.

Further, as shown in FIG. 11, when the paper layout 701 is displayed on the display range designation screen 602 so that the horizontal direction is exactly in the horizontal direction, the horizontal range is used as a reference for the display range calculation means 15. The process may be replaced with the process shown in FIG.
