Abstract

PURPOSE:To conveniently enable two margin settings by making it possible to set additional margins temporarily at a position other than the right and left margin setting positions in the normal printing. CONSTITUTION:For example, a space S is provided at a part of a printing paper. When a printing is done at other parts, as normally done, a left margin position setting key LM, a right margin position setting key RM, a space key SP and a back space key BS are used to set the left margin at the position LMPOS and the right margin at the position RMPOS1 and then, a printing is started. When the fourth line is printed, after a carriage CRG reaches the position RMPOS2, a key R.INDT is depressed to set a temporary margin position. Then, a printing is performed up to the seventh according to the right margin. After the end of printing the seventh line, the key R.INDT is depressed again to reset the margin and the printing is continued from the eighth lines on the right margin of the position RMPOS1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an electronic typewriter, and particularly to one that facilitates margin setting operations.

(Prior Art) Conventionally, electronic typewriters have allowed an operator to arbitrarily set a print start position, a print end position, and a tabulation position by a margin setting operation. However, the printing end position, which is set in advance by the operator,
In other words, even if the operator wants to temporarily set the right margin to a different position, the operator can move the carriage to the new right margin position using the space key or backspace key, and set the right margin. had to be done.

In this case, the previously set right margin position disappears, so if you want to set it again to the previous right margin position, you have to perform a new right margin setting operation, which is complicated. .

To explain this in detail with reference to FIG. 1, for example, when printing text by providing a space S where no printing is performed as shown in the figure,
In order to set the left and right margin positions, the operator sets the left margin position to the position of LMPO 9 indicating the print start position, and further sets the right margin position to the position of RMPO 91 indicating the print end position. Then, go to the 1st to 3rd rows in the diagram.
After printing from ~L3, it is necessary to provide a space S between 4th line and 7th line, so print operations while always being aware of the position of RMPO92, which is the left end position of space S. or the right margin position had to be reset to the position of RMPO32. In the latter case, when printing up to the seventh line L7 is completed, the right margin position must be reset to the position of RMPO3I in the eighth line L8, which is complicated.

(Objective) Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks and to provide a means for temporarily setting margins when creating blank spaces on printed paper, thereby making it possible to temporarily set margins with simple operations. The purpose of the present invention is to provide an electronic typewriter with the following features.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 2 shows an example of the arrangement of the electronic typewriter of the present invention,
Here, CRG is a carriage that moves the printing section (printing/printing) in the main scanning direction with respect to the printing paper, and by pressing the Svene key SP or pack space key BS, the carriage CRG is moved to the left along the guide rail GR. It can be moved within the range of limiter L/LMT and right limiter R@LMT.

LM is the left margin position setting key, RM is the right margin position setting key, and these keys LM and I'l'H
By pressing , the range of movement of carriage CRG can be set. RTN is a return key for returning the carriage CRG to a line feed, and when this key RTN is pressed, the carriage CRG returns to the left margin position and a line feed is performed. INDT is a left margin position setting key with an indicator lamp such as a light emitting diode used to temporarily change the left margin position. R・INDT is a right margin position setting key located behind an indicator lamp such as a light emitting diode used to temporarily change the right margin position. RMPO the right margin position to create S
Since this key is used to set the right margin position to 32, hereinafter it will be referred to as a temporary right margin position setting key. Fig. 3 shows an example of the system configuration of the electronic typewriter of the present invention shown in Fig. 2, where 1 is a keyboard device, including letters and symbols such as alphabet keys 1 and the above-mentioned keys for instructing various functions. Various funk keys (see FIG. 2) such as a right margin position setting key RM are provided. 2
1 is a control device that controls various components such as a keyboard device 1 and a printing device 3 (see FIG. 2) such as a serial printer. 4 is a memory device that stores information regarding the line format of left and right margin setting positions;
Reference numeral 5 denotes an alarm device that notifies that the carriage CRG has reached a temporary right margin position set by the operator, as will be described later.

Input information input from the keyboard device 1 is processed in the control device 2 according to the input. The processing results are sent to the printing device 3, memory device 4, and alarm device 5. At this time, the control device 2 reads line format information, which will be described later, stored in the memory device 4.

Memory device 4 has pointer and flag areas designated 4A-4E. 4A is a pointer indicating the left margin position set by pressing the left margin position setting key LM;
4B is a pointer indicating the right margin position set by pressing the right margin position setting key RM. 4C is a pointer indicating the position of carriage CRG. Control ifU device 2
receives the key input information from the keyboard device 1, and when the printing device 3 is operated, adds the moving speed of the carriage CRG to the value of the pointer 4C. 4D is a pointer indicating the temporary right margin position set by pressing the temporary right margin position setting key R-INDT, and the validity of this pointer 4D is determined by the value of flag 4E indicating the temporary right margin position. be done. For example, flag 4E
If the value of is °゛1゛', pointer 4D is valid,
0” is invalid.

FIG. 4 shows an example of the operating procedure of the electronic typewriter of the present invention shown in FIGS. 2 and 3, where 941 to 948
represents each step of the operator's operating procedure.

To explain the case in Fig. 1, first, after setting the left and right margin positions using the left margin position setting key LH, right margin position setting key RM, space key SP, and backspace key BS, use the keyboard device l to press the character key. Normal operations such as input operations are performed (S41). After that, when it is determined that the carriage CRG has reached the temporary right margin position RMPO32 of the fourth line L4 in FIG.
42) Press the temporary right margin position setting key R-INDT (943). Key R that lights up 1 when pressed
・After confirming that the INDT lamp is lit (S44),
Character input is performed (S45). Here, the position where the temporary right margin position setting key R@INDT is pressed becomes the temporary right margin position, and the carriage CRG is prevented from moving rightward from the above temporary right margin position RMPO32, so the temporary right margin position setting key R@INDT is pressed. Character input, etc. can be performed at the right margin position R in the same way as when the normal right margin position is set in the POS 2.

Next, when it is determined that the above character input operation between the left margin position LMPO9 and the temporary right margin position il RMPO32 has been completed (S4e), the temporary right margin position setting key R・IN[]T is pressed again. (S4?)
. This second press turns off the lamp installed in key R/TNDT, so after confirming that the lamp is turned off (84B), the process returns to normal processing (S41).
. At this time, as the lamp goes out, the temporary right margin position disappears, so the normal right margin position RMPO3I set in advance becomes valid.

Next, an example of the control operation of the electronic typewriter of the present invention shown in FIGS. 2 and 3 will be explained with reference to the flowchart in FIG. Here, S1 to S15 indicate each step of the control procedure.

After turning on the power, the normal left and right margin positions are set according to the input of the margin position setting keys LM and RM, the space key SP, the pack space key BS, etc., and the printing device 3 etc. are driven according to the input of character keys etc. A normal print processing operation is performed (Sl). After that, press the temporary right margin position setting key R.
・When INDT is pressed (S2), it is determined whether the value of flag 4E indicating the validity or invalidity of the temporary right margin position setting key is °°1゛ or not (S3), and the value of flag 4E is °°1pa. If not, after storing flag 4E ``t'' (S4)
, pointer 4 indicating the position of carriage GRG at that time.
The value of C is stored in the pointer 4D indicating the temporary right margin position (S5). At the same time, press the temporary right margin position setting key R.
-Turn on the INDT lamp (S6).

Next, when the return key RTN is pressed, the carriage CRG returns to a new line (S7), character input and printing are performed according to the key force, and the amount of movement of the carriage CRG is added to the pointer 4C (98 to 910). ). Each time an addition is made to pointer 4C, compare the value of pointer 4G with the value of pointer 4D indicating the temporary right margin position.
If the value of the pointer 4C is smaller than or equal to the value of the pointer 4D, that is, until the carriage CRG exceeds the temporary right margin setting position RMPO92, S8 is executed again.
The process returns to step 1 and repeats the above operation.

After that, the carriage CRG is moved to the temporary right margin setting position R.
When MPO9,2 is reached, the value of pointer 4C becomes pointer 4.
If it is larger than the value of D, the alarm device 5 is activated (
S12) The operator is informed that the carriage CRG has reached the preset temporary right margin position R at POS2, and the process returns to S7 to repeat the above-described operations. After that, it is necessary to cancel the temporary right margin position (S13), and press the temporary right margin position setting key R・IN.
When DT is pressed again (S2), flag 4E becomes “1°”.
Therefore, S3 becomes an affirmative judgment, and the value of flag 4E is reset to °0°' to cancel the temporary right margin position (514), and the temporary right margin position setting key R・IN is pressed.
The DT lamp is turned off (S15). Then, return to Sl and repeat the above process again.

In this example, a case has been described in which a space S where no printing is performed is provided on the right side of the printing paper as shown in the first diagram, but this space S can be moved to another part of the printing paper, for example, on the left side using the key INDT. It is also possible to provide it.

(Effects) As explained above, according to the present invention, by using a specific key to set the temporary margin position, the complexity of setting the margin position for each line can be solved, so the operation is simple. This has the effect of setting a temporary margin. Furthermore, by displaying the pressed state of the specific key using a lamp, it is possible to easily determine whether the temporary margin is in effect, thereby eliminating erroneous key operations.
