Abstract

PURPOSE:To make it possible to correct an erroneous by printed character regardless of a same line and a new line, by selecting a type on the basis of the input of a correction key by providing a daisy wheel equipped with a correct type and correcting the erroneous character. CONSTITUTION:When erroneous printing is performed by a character type 6, a carriage is moved to the direction shown by the arrow four times at the width corresponding to a pitch, that is, at the width (t) of a projection 51(52) as the whole of a correct type 50 by a pair of projections 51, 52 of said correct type 50 and, if the correct type 50 is typed, an erroneously printed character can be corrected sufficiently and certainly without generating a correction left part 30. In a correct processing procedure, a signal is transmitted to a new line flag by the input of a correct key and, when the new line flag is 1, new line processing is automatically selected and correction by the correct type 50 on a daisy wheel 40 is applied. Contrarily, when the new line flag is zero, same line correction is automatically selected and correction is applied by the same character type 50 as the erroneously printed character is applied.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic typewriter having a daisy wheel.
An object of the present invention is to provide an electronic typewriter that can easily and reliably correct erroneously printed characters.

[Conventional technology]

Printing devices that use a daisy foil, as shown in Figure 5, have much better print quality than wire dot or thermal methods, and it is easier to correct misprinted characters, so they are better suited to electronic typewriters. − is rapidly being adopted.

That is, as anyone who has ever used a typewriter has experienced, it is common to accidentally hit the wrong key due to a little carelessness, resulting in incorrect printing.

In order to prevent such erroneous printing, a daisy foil q as shown in FIGS. 6 to 8 was used. The electronic typewriter shown in Figure 5 has a correction tape (not shown).
Use instead of printing ribbon /b. Then, tap the letter ``O'' of the Dizzy foil corresponding to the incorrectly printed character (assuming the letter rr Hu) on top of it again, transfer the incorrectly printed character II HTJ to the correction tape, and peel it off from the paper/a. means are commonly used.

In addition, the collection method for electronic typewriters using conventional daisy foils is as follows: (1) Store all manually typed characters (i.e., printed characters) in a buffer, and read the printed characters regardless of accompanying or line breaks. A method of selecting and overprinting to correct typos.

[Problem that the invention seeks to solve]

However, first of all, regarding the former means, it is sufficient if the corrected type 1181g is struck in perfect agreement on the incorrectly printed character II HH of the paper/a that has already been printed, but it is possible to Due to comprehensive error factors such as errors in the movement of the carriage base back and forth, and backlash in the drive system for rotating the platen, especially when gears are used, the enlarged diagram in Figure 9 is As shown in the figure, the letter "H" that was misprinted (indicated by the solid line in the figure) and the letter "H" that was struck for correction (indicated by the broken line in the figure) rarely match completely, and it is inevitable that However, the shaded area 30 in Figure 9 (which is, of course, exaggerated in the figure) could not be removed completely, and the remaining corrections were made on paper/
It has the disadvantage that it remains on the surface of a.

In addition, in each of the above methods ■ to ■, the operability is good because the input history of all printed characters is memorized, but
The storage capacity for storage becomes enormous, resulting in a significant increase in cost.

■ Accompanying lines are memorized, so it is easy to collect them, but for line breaks, the operation is cumbersome because you have to select the same character key as the printed character each time and then press the collect key.

■ For both matching and line breaks, you have to select the same character key as the printed character and press the collect key. Although it has the advantage of being inexpensive, it is even worse in operability than ■.

[Means for solving problems]

In view of the above points, it is an object of the present invention to provide an electronic typewriter in which the collection operation is extremely simple, and furthermore, it is possible to collect data regardless of line breaks or line feeds.

Another objective is to provide a similarly inexpensive electronic typewriter.

That is, the electronic typewriter of the present invention is characterized in that it has a daisy wheel with correct type, and the correct type is selected by inputting a correct key to correct misspellings.

〔Example〕

The configuration will be described in detail below based on one embodiment shown in the drawings.

In the electronic typewriter of this invention, it is important to have a daisy wheel with collect type.

Examples are shown in FIGS. 1 and 2.

In the figure, the daisy foiler O is the same as the daisy foiler described above, except that it has a collect type, 50, which will be described in detail below. That is,
It can be considered that one of the letters O formed at the tips ja of the plurality of spokes δ of the daisy wheeler illustrated in FIG. 6 has been replaced with the one shown in FIG.

In FIG. 1, the symbol 5/1. S, 2 is a pair of protrusions arranged opposite each other at a predetermined interval, constituting the collect type 50 which is the main part of this invention, and one spoke J of a plurality of spokes 6 extending radially at equal intervals. It protrudes from a base 68' having a rectangular cross section formed on the front surface side of the tip.

This collect type, 50 protrusions, s/1.5,2, is located at the tip of the other spoke 6, as shown in an enlarged view in FIG.
A virtual area 100 (2 in the figure
The area 100 is indicated by a dashed dotted line, its width is indicated by the symbol H, and its height is indicated by the symbol H, and the character # HH2 is used as an example of a single character.
It has a height h greater than the height H of II (indicated by II, it n), which is sufficient to cover even if error factors such as the aforementioned backlash occur.

Another pair of ridges! ;/1.5. ．． The pitch width of No. 2 is also set at a pitch p that takes into consideration the ``amount of deviation'' from -Pa''L/2 when it is the width of the area 100. In addition, the width t of the protrusions j/1, 5, and 2 is set larger in this example than the line width T of the character u HI+ shown as an example of the character type O shown in FIG. 7, and the pitch p p/t is set to exactly 4 so that it is an integer fraction of . Therefore, as shown in Figure 3, no matter which character type B misprints, the correct type, 5
A pair of protrusions of 0, 5/, , S, 2 collect the typeface, 50 as a whole, with a width corresponding to the pitch ρ, that is, a protrusion, 5/(,5,2) with a width t of the carriage only 4 times. By moving in the direction of the arrow and hitting the correct type 50, the misprinted characters can be sufficiently and reliably corrected without producing the uncorrected portion 30 as shown in FIG.

Next, a method of correcting typographical errors by selecting the correct printed character JO by inputting the correct key will be described.

First, in the present invention, the term "coincident collect" refers to making the line at the current position of the carriage head the same without performing line feet (up or down), and collecting that line.

1st line A B CD E F G A B CD E
F G HI J22nd line ABCDEFGHIJDC
FGHIJ 3rd line ABCDEFGHIJABCDEF
I 4th line D E F G HI J A B CD
'E F G HI J55th line CDEFGHIJGH
Im BCDEF, that is, in the above example, the first line ~
If you type up to the 5th line and the carriage head is positioned at the 5th line, a collect within the 5th line is called a co-collect.

Also, line feed collection refers to collection with a line feed (up or down). In the above example, from line 5 to 4
It refers to the collection in which paper is fed up and down from the 5th line as a reference column, such as the 5th line, the 2nd line, or the 9th line.

In this invention, first of all, the correct type character 50 of the daisy foil lIO is selected by inputting the correct key to correct typographical errors. That is,
Inputting the correct key at any position, whether on the same line or at a new line, selects the correct type, 50, on the daisy foil ltO, and the typo is corrected by that type.

1st line 8BCDEFGHI 2nd line JKLMNOPQRyo≦h～3rd line υDE
FGHIJK Δ In this case, the correct type is selected by inputting the correct key for the incorrectly printed character, regardless of whether it is the same character or a line break, so the incorrect character is corrected by hitting the correct key a predetermined number of times.

Next, as a second invention, in the case of the same collection h, just by inputting the collect key, a novel is selected and collected from the same character type as the 4 incorrectly printed characters, as in the conventional case. On the other hand, in the case of line feed collection, I.

Just by inputting the correct key, the correct typeface, 50, is selected and the typo is corrected.

In this case, the correct processing procedure is as shown in Fig. 4. When the correct key is input, a signal is transmitted to the line feed flag, and when the line feed flag = 1, the line feed correct processing is automatically selected. Correct 1- is applied. Conversely, when the line feed flag is -0, the accompanying cholera 1-processing is automatically selected, and correction is performed using the same printed characters as the erroneously printed characters.

As shown in the figure, the line feed flag changes to -"]" after the line feed or line indent processing, and is reset to 0 by inputting a carriage return.

Another example of the line break flag created by Gino is to set up a Rororo on the keyboard to set the line after the line feed as a co-collect. The information may be stored in a buffer to enable simultaneous collection.

In addition, in the second invention mentioned above, the accompanying collection can be done in the same way as before.
Cork 1 - The reason why the buffer is selected only by key input is 5 in the case of simultaneous collect compared to line feed collect.
Since there is no need to move the paper/a up and down, the drive system,
This is particularly because there is less concern about gear backlash and paper slippage, and even when incorrectly printed characters are selected and overprinted, there are only a few remaining 3o to be corrected.

〔Effect of the invention〕

Since the electronic typewriter of the present invention is constructed as described above, incorrectly printed characters can be easily and reliably corrected simply by inputting the correct key.

Also, since there is no need to use large memory capacity,
An inexpensive electronic typewriter can be provided.
