When the CPU 11 is started, it selects a program, and if the program is set, then FIG.
The setting process shown in is performed. In this setting process, a default value is first set, and in this state, if there is a key input of the set value from the keyboard 4, the default value is changed to the set value, and if there is a key input of the end key 4d, the set value is stored in the RAM 13. Store and end this setting process.
In this setting process, the liquid crystal display 6 is shown in FIG.
As shown in (c), the window opens and each window level is displayed. This is done by specifying and inputting a numerical value.

First, the reading of a sheet, for example, a slip sheet, by the image scanner 2 is checked, and if there is a reading, the read image data is displayed on the liquid crystal display 6.

The screen display at this time is as shown in FIG. 10, for example. The slip image data is displayed on the upper portion A of the screen, and numerical values of "1234 ... 90" are displayed at each printing position so that the position, the number of digits, and the character type can be seen at a glance. If the printing is left-aligned, select "1234
The numerical value "..." indicates the character position, and when the printing is right-aligned, the numerical value "1234 ..." from the right indicates the character position. Further, a portion q enclosing a character in the drawing is shown by a white inverted character, and that portion shows a step currently being edited.

The command of the corresponding step portion is displayed on the lower part B of the screen. For example, two commands are described in the # 002 step. The A command is "A'Enter product name (+) '[B]" and the P command is "PB". Explaining how these commands operate when an application program is executed, the A command is a character input command,
An input guide message "Enter product name (+)" is displayed on the screen to prompt the user to enter a key, the entered value is displayed in the highlighted part on the screen, and then memory "B" is displayed.
Command to be stored as data in. This command refers to the line column information in the step information, the number of step digits, the character pitch, the presence / absence of even division, left / right alignment, the character size, the character type, and the window position.

The P command is a print command. "B"
Prints the contents of the memory. This command refers to line column information in the step information, character pitch, left / right alignment, character size, and character type.

The command "N 'input quantity (+)'[C]" in step # 003 is an N command, and this command is a numerical value input command. This command also refers to step information.

Further, in step # 004, "B = B2.
There is an arithmetic expression "Z", which is a command for transferring the contents from the memory "B2.Z" to the memory "B", and this command does not refer to step information.

It is the interpreter that parses and executes these commands.

Further, in the lower part C of the screen, the corresponding step (# 00
Line information (012 + 09) and column information (016 + 0) in 2)
0), character type (H), step digit number (010), left and right alignment,
Evenly divided, character size (standard size), character pitch (025
dot) is displayed.

When the image data is displayed on the screen, the one-step display process is repeated until the end step.

In this one-step display process, as shown in FIG. 11, first, it is checked whether the alignment is right alignment or left alignment. If right alignment is performed, numerical data is displayed from the right of the print position with the specified character size, character pitch, number of digits, and character type. In case of left alignment, numerical data is displayed from the left of the print position with the specified character size, character pitch, number of digits, and character type.

Subsequently, it is checked whether or not this step is the step currently being edited. If it is a step to be edited, a triangle mark r, which is an index symbol, is displayed at the print position to indicate whether the print start position of this print position is right-aligned or left-aligned. For example, the triangular mark r at the printing position q in FIG. 10 indicates left alignment.

Then, the print area is indicated by white reverse display.

In this state, by operating the arrow key 4e on the keyboard 4, the cursor on the screen can be moved to move the step currently being edited. The movement reference in this case is the vertical and horizontal dot densities of the printer 8, and this value is converted to the dot density of the image data to be the movement position on the display.

When the print position of a certain item is determined and the execute key 4b is operated, the position information and the attribute information are stored in the step information storage section of the information storage memory 131.

Then, a command input process is performed.

When the print position of each item is determined and the position information and the attribute information are stored in the step information storage section 131 repeatedly, and finally the end key 4d of the keyboard 4 is operated, the creation process is ended. It is supposed to do.

Further, the CPU 11 is adapted to perform the execution processing shown in FIG.

In this execution process, when the image scanner 2 is used, the stored image data is read, and a flag to be passed to the display driver is set based on whether or not the 1/2 display is designated.

The display driver controls the display when the image data or the command is executed based on this flag. That is, if it is 1/2 display, 1/2 display processing is performed, and if 1/1 display, 1/1 display processing is performed. In the 1/2 display processing, the image data and the display data by the command command are displayed on the screen of the liquid crystal display 6 in a form in which vertical and horizontal even dots are thinned out. The display position is also the coordinates of the vertical and horizontal directions divided by two.

That is, when the size of the image data read by the image scanner 2 is as shown in FIG. 13, when the 1/1 display processing is performed on the screen of the liquid crystal display 6, the screen shown in FIG.
Although it is possible to display only a part of the whole as shown in (a) of Fig. 14, if this is ½ displayed, it becomes as shown in (b) of Fig. 14, and the entire image data read by the image scanner 2 is displayed. Will be done.

Next, after setting the step information and analyzing the command, the presence or absence of display data is checked. If there is no display data, the command is executed. If there is display data, the 1/2 display mode is selected. For example, 1/2 reduced display processing is performed, and in 1/1 display mode, 1/1
Is displayed.

The above process is repeated until the end key 4d is operated on the keyboard 4, and when the end key 4d is operated, this process is ended.

With such a configuration, first, the slip sheet is read by the image scanner 2 and displayed on the liquid crystal display 6. At this time, when the image data of the slip paper read by the image scanner 2 is larger than the screen of the liquid crystal display 6, the fixed item designation program is selected from the main program of the window level 1 in the setting process, and the designation of the fixed item is performed. Wind level 2 belonging to the program
The display of the image data is selected from, and the display of 1/2 at the execution is selected from the window level 3 belonging to the display of the image data.

Then, the print position and the print area are created for the read image data of the slip paper. In this creation process, the display process is repeated step by step. When right adjustment is performed in this process, numerical data is displayed from right to left according to the specified character size, character pitch, number of digits, and character type.
... "is displayed. Then, in the case of the current editing step, the triangular mark r which is an index symbol is further displayed facing left. In addition, the print area is highlighted in white.

In the case of left alignment, numerical data is displayed as "1234 ..." From left to right with a specified character size, character pitch, number of digits, and character type. Then, in the case of the current editing step, the triangular mark r which is an index symbol is further displayed rightward. In addition, the print area is highlighted in white.

As described above, when the print position is created, the print position, the character size, the character pitch, the number of digits, and the character type can be easily confirmed by the numerical data. That is, it can be confirmed by the printed image. Further, it is possible to easily confirm right alignment or left alignment by the arrangement of the numerical data and the direction of the triangular mark r which is an index symbol. Moreover, the print start position can be easily confirmed by the triangular mark r.

When the setting of the print position for the image data of the slip sheet read by the image scanner 2 is completed in this way, the image data can be read and printing on the slip sheet can be executed. In this execution process, the image data of the slip sheet read by the image scanner 2 is reduced to 1/2 and displayed on the liquid crystal display 6. Thus, at the time of execution, the entire image of the slip sheet can be confirmed on the screen of the liquid crystal display 6. Therefore, the execution work can be easily performed while looking at the display screen. In addition, the screen does not scroll and flicker on the screen can be eliminated.

In the above embodiment, the image scanner 2
The image data read in step 2 is reduced to 1/2 and displayed on the screen, but the invention is not limited to this. For example, reduction of 1/3 or 2/3, etc. It is sufficient to reduce the size so that it can be displayed on the screen.
