Abstract

PURPOSE:To easily make the layout of columns by eliminating the need for the input of positional letters by a method in which a switch to decide whether the positioning of numeral information should be or should not be made is provided and printing columns are set according to the input numeral information. CONSTITUTION:When a numerical key ''4'' is pushed down and 1234 is displayed on a displayer DSP, ''4'' is stored in registers L and C1 and ''3'' is in the register C2. When the register C2 becomes ''3'' and a slide switch SS selects a positioned information, ''1'' is stored in the register C3 and at the same time the register C2 is cleared. The value of the register C3 is number of positioned letters in numeral row to be printed. When a control key DS is then pushed down, the value ''4'' of the register L is added to the value ''1'' of the register C3 by CPU, the value ''7'' obtained by adding ''2'' to the result is stored in the register L, and the position T2 of 7th line from the tab stop position T1 is stored as 2nd tab stop position in a memory MRY.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device C1, and more particularly, in a printing device C such as an electronic typewriter having a tabulation function, the printing position (-automatically (= An electronic typewriter (1
It is related to

When tabulating using an electronic typewriter, the user needs to calculate and lay out the spacing between each column in order to set the printing position of each column precisely (hereinafter referred to as column layout). If you want to scale the decimal point position of each column, set the decimal point position
When trying to set the second setting, I had to enter the scale character from the keyboard along with the numeric keys.

For this reason, inputting scale characters becomes complicated, and the number table 1
Column layout work in = is one of the most disliked tasks.
They were one.

The present invention was made in view of the above circumstances, and has a C-configuration that eliminates the trouble of inputting scale characters and allows the column layout in the numerical table C2 to be performed extremely easily and at high speed. The purpose is to provide a printing device.1. I'm here.

In order to achieve the above object, the present invention C2 is provided with a switch for selecting whether or not to scale the numerical information entered by the C2 person, and the selection of this switch (2) settings (-
A new structure was adopted.

Hereinafter, the present invention will be described in detail based on the drawings (two embodiments shown).

FIG. 1 is a block circuit diagram illustrating an embodiment of the invention, in which KB indicates a keyboard, in addition to various keys such as character keys and numeric keys, C-control key D'S and printed numbers. The column is equipped with a slide switch SS that allows you to select whether the scale is ok or not.

A register designated by the symbol KR stores information about keys input from the keyboard KB. A DSP is a display device, for example, a fluorescent display tube capable of displaying 20 digits, and an MR
Y indicates memory that stores tab stop positions.

The CPU is a central processing unit and is provided with internal registers 1''- and 01-C3.

Next, the operation of this embodiment configured as described above will be explained.

For example, using the letter keys on the keyboard KB, rAJ,
When rBJ,,jCJ are input, the display device DSP
As shown in Figure 3(a) (-), (2 father and son "AB'cJ" is displayed and (2 CPU register L (213) is stored. This number is entered for 3 characters. At this time, the input keys for registers 01 to C3 are not numeric keys, but are all character keys (3), so their contents are up to "0".

゛ When the control key DS is pressed here, the CPU adds the contents r3J of register L and the contents ``0'' of register C3, and stores the value ``5'' obtained by adding this (Y12) in the register. , the left margin L of table T as shown in Figure 2 (2)
The position T1 of the fifth row from M is stored in the memory MRY2, and at the same time, the registers C1 to C3 are cleared to "0".

The reason for adding "2" to CPU l- is to make the table easier to read (- to create two digits of blank space).

Next (2) When the numeric key rlJ is pressed from the keyboard KB, the register KRI key information is stored and the display device DS'Pf2 is displayed as shown in FIG. 3(b).

Then, "1" is stored in register C22. At this time, since the key input is a number, "1" is also stored in the register C1.

Next, when the two numeric keys r2J and r3J are pressed, the display device displays (2J123J) as shown in FIG. 3(c), and the value of register L is incremented to store "3". Since the input key for CN2 is (4), all of them are numbers, ≦ - "3" is stored in the same way as register L. Also, register C2 is incremented when a number key is input when the value of register C1 is not O. (- "2" because it is configured.

"2" is stored from the key C2 of "3". Next (Second) When the number key “4” is pressed, the display device DSP
As shown in Figure (d), f knee [1234J is displayed, "4" is stored in register L, CI+=, and "3" is stored in C2.

And in register C3, register C2 is "3" (2),
And when the slide switch SS is selected to "with scale", "1" is stored, and at the same time, the register C2 is cleared. The value of C3 is the number of scale characters in the numeric string to be printed.

Next (When the second control wholesale key DS is pressed, the CPU
Add the value "1" of (O14J and register C3), store the value "7" given as the result (Y12) in the register, and set the tab stop position in the first column of the table in Figure 2. T
The position T2 of the 1st to 7th rows is stored as the second tab stop position in the memory MRY.

Further (2. If you enter the "$" key from the keyboard KB -
The character information is stored in the register KR (-) and displayed as 1$1 in the display device DSP +1 as shown in FIG. 3 (e). "1" is stored in the register C2 in the CPU. However, since the input information is not a number, register C1 remains at "0".Next, press the number keys rlJ, r2J, r3J.

When you press "4", the display device DSP will display the figure 3 (fl(
= As shown, C2 "$1234" is displayed, and register L in the CPU (- is 1-5J, CI is "4".

C2 (- is stored as "3", and at this time, the contents of register C2 are 13", so "1" is stored in register C3, and register C2 is cleared. Also, continue by pressing number key r5J , r6J and r7J are pressed, the display device DSP +: becomes (2[,
$1234.567J is displayed and the register is [8J
, CI becomes "7J", C2 becomes "3", and as mentioned above (-register C3 is incremented by the contents of register C2 becoming "3" (2), "2" is stored, and register C2 is cleared. be done.

When the control key DS on the keyboard KB is pressed here,
The CPU adds the contents of registers L and C3 and the result is +-
The value "12" obtained by adding "2 J" is stored in register L,
Tab stop positions T2 to 1 in the second column of the table shown in Figure 2
In the second line C2, the tab stop T3 is stored in the memory MRY-2 as shown in FIG.

Then, the four registers in the CPU are cleared.

In this way, since printing can be performed while automatically performing column layout, the user does not have to perform troublesome calculations for the layout, and it is extremely easy to create tables of numbers. .

As is clear from the above explanation, C-1 according to the present invention, there is provided a switch for selecting whether or not to scale numerical information, and according to the selection of this switch, the printing column is set according to the input numerical information (1). Because it is structured so that it is possible to set a tab stop at the launch position of each column of the C1 table without worrying about scale (7), it is extremely easy to create a table of numerical values, and the table can be created in an easy-to-read manner. be able to.
