Abstract

PURPOSE:To temporarily release an indent position by permitting a carrier to move from the indent position to the head of a line before the line is changed when a command for temporary release of the indent position is input through a keyboard. CONSTITUTION:When an operator sets a carrier 16 to a margin position which becomes the head of a line on a paper 14 and presses a margin setting key on a keyboard 10, an MPU 60 reads out the position in a direction of the line of the carrier from a second memory 54 and stores the position of the left margin in a fourth memory 58. When the carrier comes to the position of the line as the indent position and a setting key on the keyboard 10 to set the indent position is depressed, the MPU 60 reads out the current position of the carrier 16 from the second memory 54 and stores the position as an indent position into a third memory 56. When it is ordered through the keyboard 10 to change the line after characters of the first line are input and printed, the MPU 60 makes the carrier 16 movable only rightwards from the indent position. Therefore, characters can be input and printed from the indent position at a second line.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a printing device.

(Prior Art) When creating a document in the format shown in FIG. 3 on a conventional electronic typewriter or word processor, the left margin position (shown by straight line E1), which is the beginning of each line, and a predetermined distance from the left margin to the end of the line. By setting an indented position (shown by a straight line 12) that is downward in the direction, it becomes easier to create a document. To create the document shown in Figure 3, enter the character string "1-1" in the first line starting from the left margin l, then input the character string "1-1" at the indent position 12, that is, the first character of the word "Makes" in the first line. Input the position of "M" into the microcomputer system and store it. Indent position yttt.

If you set , and after inputting all characters on the first line, instruct a line break, characters on the second line can be input from the indented position 2□ toward the end of the line. Thereafter, up to the fifth line, characters can be input automatically from the indent position 12 toward the end of the line. Then, when inputting the character string °“1-2” on the 6th line, the left margin l +
Since you have to input from , after finishing inputting the character on the 5th line, -dan indentation position l! After inputting the cancellation, perform a line break. Then, characters can be input from the left margin 21 on the sixth line. However, from the 7th line onwards, characters must be input from the previous indentation position 12, so the position of the first character "M'" of the word "MONO" on the 6th line is again input to the microcomputer system as the indentation position. Make me remember.

Therefore, if you specify a line break at the end of each line starting from the 7th line, the character input for each line will be at the indentation position l! It becomes possible from

(Problems to be Solved by the Invention) However, the above conventional indent position setting method has the following problems.

- Once you instruct to cancel the indent position, even if you want to set the same indent position again, you will have to set it again from the beginning. In particular, when setting and canceling the indent position are repeated, the operation becomes complicated and the operator's work efficiency is reduced.

Therefore, an object of the present invention is to provide a printing device that can temporarily release the indented position.

(Means for solving problems) In order to solve the above problems, the present invention has the following configuration.

In the case of an electronic typewriter as a printing device, there are character keys that specify the characters to be printed, including spaces, line breaks, indentation settings that move the printing start position on the paper down by the specified amount from the beginning of the line, and temporary settings for the indentation positions. a keyboard having a function key for instructing release, etc.; a storage means for storing the indentation position; a carrier position detection means for measuring the current position of the carrier in the row direction; and setting of the indentation position from the keyboard. When an instruction is input, the current position of the carrier detected by the carrier position detection means is stored as an indentation position in the storage means, and when an instruction to temporarily cancel the indentation position is given from the keyboard, a line break is performed. control means that enables the carrier to be moved from the indented position to the beginning of the line until the indentation is performed; and, in the case of a word processor among printing devices, on the other hand, it instructs the character to be displayed on the display including spaces. Setting the character key, line break, and indentation position to move the display start position on the display down by the specified amount from the beginning of the line,
(a) a keyboard having a function key for instructing temporary release of the indentation position, a storage means for storing the indentation position, and a cursor position detection for measuring the current position of the cursor in the line direction on the display; and storing the current position of the cursor detected by the cursor position detection means as an indentation position in the storage means when an instruction to set an indentation position is input from the keyboard, and temporarily canceling the indentation position from the keyboard. The present invention is characterized by comprising a control means that allows the cursor to move from the indented position to the beginning of the line until a line feed instruction is input when an instruction is given.

(effect) The effect will be explained.

When a temporary cancellation of the indent position is instructed from the keyboard, the indent position will be canceled until the next line feed or line feed instruction is input, and after the line feed or line feed instruction is input, the previous indent position will be adopted again, so the same indentation will not occur. If it is a position, there is no need to set the indent position again.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of the printing device of this embodiment, which has the functions of both an electronic typewriter and a word processor by operating a mode changeover switch, and FIG. 2 is a block diagram thereof.

First, the configuration will be explained.

Reference numeral 10 denotes a keyboard, which includes character keys for instructing letters, numbers, and symbols (hereinafter referred to as characters) including spaces to be printed on the surface 14 of the paper 12 or displayed on the display 62, and for setting margins, line breaks, indent positions, It consists of function keys for instructing temporary release of indentation, cancellation of indentation, cursor movement, etc.

16 is a carrier, which is moved in the left-right direction by a carrier motor 20 driven via a carrier driver circuit 18. For example, the carrier 16 rotates one character each time the carrier motor 20 rotates 1/8.
(Example: 1/10 inch) It is designed to move left and right. The carrier 16 moves to the right when the carrier motor 20 rotates in one direction (forward direction), and moves to the left when the carrier motor 20 rotates in the other direction (reverse direction). The carrier 16 is provided with a type wheel 22 commonly called a daisy wheel, and the type wheel 22 is driven by a wheel motor 2 driven via a wheel driver circuit °24.
6, and the type of type is selected by the rotating position of the wheel motor 26.

The selected characters are struck onto the paper surface 14 by the type hammer 28 via the ink ribbon 27 and printed on the paper surface 14. The type hammer 28 is actuated by a hammer solenoid 32 driven by a hammer driver circuit 30. The above-mentioned printing means such as the type wheel 22 and the type hammer 28 are movable in the row direction (left and right direction) together with the carrier 16. When the printing means is in the typewriter mode, when a character is input from the keyboard 10, the printing means prints the character on the paper surface 14 of the paper 12, and when the printing means is in the word processor mode, it prints the stored character group (text) when there is a printing instruction. After that, they are printed all together on the paper surface I4 of the paper 12.

The paper 12 is pressed against the outer peripheral surface of a platen 44 by a roller (not shown) or the like, and by rotating the platen 44, it is possible to change the printing line. The platen 44 rotates with the rotation of a platen motor 48 driven by a platen driver circuit 46, thereby enabling a changeover operation. For example, the platen motor 48 is
When the platen 44 rotates three times, the platen 44 rotates by one line.

The printing device according to the present invention is controlled by a microcomputer, and the system will be explained.

A RAM 50 includes a first memory 52, a second memory 54, a third memory 56 serving as a storage means, and a fourth memory 58. In typewriter mode,
The first memory 52 stores characters input from the keyboard 10 and printed on the paper surface 14 and the printing position of the characters on the paper surface 14. The second memory 54 stores the current position of the carrier 16. The third memory 56 stores the indentation position, and the fourth memory 56 stores the indentation position.
8 stores the margin position. Character page 14
The upper printing position is the carrier or cursor position detection means, and the microprocessor (MPU) is the control means.
60 is detected as the position of the carrier 16. The position in the row direction is determined by MP from the rotation direction and amount of rotation of the carrier motor 20.
For example, U60 calculates the distance from the home position.

On the other hand, the position in the vertical direction with respect to the paper surface 14 can be determined by the MPU 60 measuring the rotation direction and amount of rotation of the platen motor 48, and can be determined by the distance from the print start line, for example. In addition,
The MPU 60 constantly measures the position of the carrier 16 in the row direction and stores it in the second memory 54 .

In the word processor mode, the first memory 52 stores characters input from the keyboard 10 and displayed on the display 62 and the positions of the characters on the virtual surface represented on the display 62. The third memory 56 also stores the indent position, and the fourth memory 58 stores the margin position. The display position of the character on the virtual plane is detected by the MPU 60 as the position of a cursor (not shown) on the virtual plane expressed on the display 62. The position in the row direction is determined by the MPU 60, for example, as a distance from the home position, and the vertical position of the virtual plane can be determined by the distance from the display start row. Note that the MPU 60 constantly measures the position of the cursor in the row direction and stores it in the second memory 54.

The MPU 60 acts as a control means and controls the operation of the printing device according to the control program 82 loaded in the ROM 80. Next, the operation will be explained.

First, the case of electronic typewriter mode will be described.

When creating the document shown in FIG. 3, the operator positions the carrier 16 at the margin position 11, which is the beginning of a line on the paper surface 14, and presses the margin setting key on the keyboard 10. Then MP
U60 reads the position of the carrier 16 in the row direction from the second memory 54 and stores the position lI of the left margin in the fourth memory 5th.

And left margin 1. The first sentence is input and printed, and when the carrier 16 reaches position 12 in the line direction, which is the indentation position, the indentation position setting key on the keyboard 10 is pressed. Then, the MPU 60 reads the current position of the carrier 16 from the second memory 54 and stores position 12 in the third memory 56 as an indented position. After inputting and printing characters on the first line, when a line feed is instructed from the keyboard 1O, the MPU 60 allows the carrier 16 to move only to the right of the indented position 12. Therefore, characters can be input and printed from the indented position 12 on the second line. Thereafter, characters can be input and printed automatically from the indent position 2 until the fifth line. When inputting and printing the characters on the 6th line, it is necessary to print from the left margin 21, so after printing the characters on the 5th line, press the temporary release key for the indent position on the keyboard 10. The MPU 60 determines that the indented position is temporarily canceled and allows the carrier 16 to move to the left from the indented position 12. At this time, the contents of the third memory 56 are retained as they are. The 6th line is left margin I because the indentation position has been temporarily canceled.
From 11 onwards, characters can be input and printed. When the line feed key on the keyboard 10 is pressed or the platen 44 is rotated to perform a line feed after printing of the sixth line is completed, the platen motor 48 rotates and the MPU 60 determines that the temporary release of the indented position has ended. As for the seventh line, the indentation position it is again based on the contents of the third memory 56.
Movement of the carrier 16 further to the left is prohibited. As a result, characters can be input and printed from the indented position 2□ again from the seventh line onwards without any special key operations.

In addition, if you want to change the indentation position, use carrier 16.
If the user moves the key to a new indent position and presses the indent position setting key on the keyboard 10, the contents of the third memory 56 are updated and a new indent position is set. Also, if you want to eliminate the indentation position, use keyboard 10.
When the indentation position cancellation key is pressed, the contents of the third memory 56 are cleared and the indentation position is canceled.

Next, the case of word processor mode will be described.

Similarly, when creating the document shown in FIG. 3, the operator places a cursor (not shown) on the display 62 at the margin position 11 on the display 62 and presses the margin setting key on the keyboard 10. Then, the MPU 60 reads the position of the cursor in the row direction from the second memory 54 and stores the left margin position Wtt+ in the fourth memory 58.

Then, input the first sentence from the left margin l, and when the cursor reaches the position it in the line direction to be the indent position, press the indent position setting key on the keyboard IO. Then, the MPU 60 reads the current position of the cursor from the second memory 54 and stores it in the third memory 56 at the position i2.
is stored as the indentation position. After inputting characters in the first line, if a line break is instructed from the keyboard 10, the MPU 60 allows the cursor to be moved only to the right of the indented position 12. Therefore, characters can be input from the indented position 12 on the second line. Thereafter, characters can be input automatically from the indented position up to the fifth line. When entering the character on the 6th line, you must enter from the left margin l, so after displaying the character on the 5th line, press the keyboard 10.
Press the temporary release key at the indent position. The MPU 60 determines that the indentation position is temporarily canceled and allows the cursor to move to the left from the indentation position 2. At this time, the contents of the third memory 56 are retained as they are. The indent position has been temporarily canceled, so the 6th line has a left margin l,
You can now input characters. After the sixth line is displayed, press the new line key on the keyboard 10, and the MPU6
0 is determined to be the end of temporary release of the indent position. Regarding the seventh line, movement of the cursor to the left from the indentation position 12 is again prohibited based on the contents of the third memory 56. As a result, from the 7th line onwards, characters can only be input from the indentation position W12 again without any special key operations.

If you wish to change the indentation position, move the cursor to a new indentation position using the cursor movement keys on the keyboard 10 and press the indentation position setting key on the keyboard 10, and the contents of the third mesori 56 will be updated.
A new indentation position is set. Further, if the user wishes to cancel the indented position, by pressing the indented position cancel key on the keyboard 10, the contents of the third memory 56 are cleared and the indented position is canceled.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments (it goes without saying that many modifications can be made without departing from the spirit of the invention). be.

(Effects of the Invention) When using the printing device according to the present invention, if you want to temporarily cancel the indentation position while inputting a document, you can erase the stored data of the indentation position by pressing the key once. Since the previous indentation position is automatically and reliably restored when moving to the next line, the operator does not need to reset the indentation position. Therefore, it is particularly convenient for creating documents that require temporary cancellation of the indented position many times, and is particularly effective in reducing the burden on the operator and improving work efficiency.
