Abstract

PURPOSE:To express the leading character of one sentense by a capital and the succeeding characters by small letters and putting a period on the final position to reduce an input error, by specifying capital shift automatically after inputting the period, and after input of the capital, specifying small letter shift automatically on the basis of the specification of the capital shift. CONSTITUTION:A mode alteration switch SW is fitted to an English word processor. After inputting a period, the switch SW specifies the switching to one of a capital/small letter specifying mode or a normal mode. The switching state of the switch SW is inputted to an AND gate 10, and when a period signal P specifies the shift mode, an FF20 is set up. When a capital signal L is inputted from the FF20, the output of the FF20 is inputted to an OR gate 30. A capital/small letter shift key operating signal B is inputted to the gate 30 to express the leading character of one sentense by a capital automatically and the character on and after the 2nd by small letters and output a period finally, so that the operation of character input is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an automatic uppercase/lowercase shift designation system that is particularly suitable for manual key operations in English word processors, English typewriters, and the like.

[Technical background of the invention]

In general, when inputting all English text by manually operating keys on a key-powered device provided in an English word processor, etc., character input operations are required to specify an uppercase shift to input all uppercase letters or a lowercase shift to input lowercase letters. In addition, a shift operation (shift key operation) is required.

By the way, a typical sentence in English begins with a capital letter in the first digit (first character) and ends with a period.

Therefore, in order to manually input English text, the operator must press the period at the end of one sentence and then move on to the next sentence. Manually operate the key (first letter of ). The operator then stops operating the uppercase shift key.

As a result, the characters entered manually (second board 14)
) are entered in lowercase.

[Problems with background technology]

In this way, when manually inputting English text using a conventional key-operated device, all operations for specifying the uppercase `` shift must be performed after the manual input of a period, which has the disadvantage of poor work efficiency and the inability to improve office efficiency. In addition, there is also the drawback that input errors caused by errors in shift designation operations, such as inputting the first character of one sentence as a lower case letter, occur frequently.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to
You can automatically specify an uppercase shift after entering a period.
Based on this specification, after inputting an uppercase letter, the lowercase letter shift specification is automatically performed, which means that the first character of one sentence, such as English, is a human character.

To provide an automatic uppercase/lowercase letter shift specification method that significantly improves manual operation and reduces input errors for sentences in which the second and subsequent characters are non-letters and the last character is a period. It is in. , [Summary of the Invention] The present invention focuses on the structure of sentences such as English sentences, in which the first letter is a capital letter, the second and subsequent letters are basically 1jJ, lowercase letters, and the last is a period. After inputting -, specify uppercase/lowercase shift finger >r! By configuring the double signal movement fJ-J to be output, the human-powered character of the bold character (the first character of the next sentence) is manually created as a human character without performing an uppercase shift specification operation, and the human-powered character of the bold character is Afterwards (1-11, by configuring the state to automatically change so that the uppercase/lowercase or γ shift designation signal specifies the lowercase i knot), the state can be changed without any shift designation operation. The input characters up to the period are entered manually in lower case. Also, I would like to be able to input an uppercase letter within one step of inputting a lowercase letter.
After inputting the uppercase letters of AA u and HO, I want to manually enter the lowercase letters of 11 and 1. Meiji is designed to allow shift specification by 1, uppercase/lowercase letter shift specification operation. There °

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Note that this example is a case in which the first character of one sentence is a capital letter, the second and subsequent characters are basically lowercase letters, and the last character is a period. It can also be applied to devices that can handle text input, such as English typewriters. Further, the input device may be an input device capable of inputting German, Russian, etc., and these input devices may be, for example, a tablet-type input device d as well as a key-powered device.

The drawing shows the main structure of a key human-powered device in an English word processor to which the present invention is applicable. In the figure, S

By using human power, the above capital letter signal is
This is a signal that can be generated by pressing the alphabetic key fF- when the human character shift finger is pressed. 3
0 is F/F,? This is an OR gate (hereinafter referred to as OR) to which the Q output of 0 and the upper/lower case shift key operation signal B are input.

030 outputs an uppercase/lowercase character shift designation signal A in response to these input signals. The above uppercase/lowercase shift key operation signal B is the uppercase/lowercase shift key (not shown)
'C is generated in response to the key operation, and is logic "0" in the normal state, and becomes logic "1" when the key is operated.

In this embodiment, the shift key operation signal B is set to logic 6.
If you want to keep it at 1", you can operate the lock key (not shown) together with the uppercase/lowercase shift key. Also, the above uppercase/lowercase shift designation signal A is for specifying uppercase/lowercase shift. A logic "1" specifies an uppercase shift, and a logic "0" specifies a lowercase shift.

The entire operation of an embodiment of the present invention will be briefly explained. Now, with the mode changeover switch SW switched to the contact C8 side as shown in the figure, for example, "Mynameis Junji T
It is assumed that arnuraJ is entered manually, and then a period indicating the end of one sentence is entered by operating the period key. As a result, a period signal P of logic "work" is generated. ANDJ (7) opens the gate by switching the mode changeover switch SW to the contact C1 side and outputs the period signal P as it is to the set input terminal S of the F/F 20. As a result, the F/F 20 is set. and its Q output is logic “1”
”.The Q output of F/F, ?o is input to one input terminal of 0R30, and the uppercase/lowercase shift key operation signal B is input to the other input terminal.Uppercase/lowercase shift key (not shown) In the normal state where the key is not operated, the uppercase/lowercase shift key operation signal B is logic "0", so the uppercase/lowercase shift key operation signal B, which is the output of OR30, is output to the Q output of F/F20. In this case, Q - @ 1'', and the uppercase/lowercase letter shift designation signal A becomes ``l''. As a result, the uppercase letter shift is specified without operating the uppercase/lowercase letter shift key. According to the embodiment, an uppercase shift is automatically specified in response to a period input. Therefore, as the next sentence, for example, "I l
iv* in Yokohama, If the operator wants to manually input the key J, instead of operating the uppercase/lowercase shift key as in the past, the operator should first operate the alphabetic key that indicates the first alphabetic character "■ (i month.") This key The operation will input the capital letters "IJ".

When an uppercase letter is entered, an uppercase signal is generated. This uppercase signal is input to the reset input terminal H of F/F2 (7). As a result, F/F20 is reset and its Q output changes from logic "1" to logic "0". The uppercase/lowercase shift designation signal A, which is the output of 0R30, becomes logic "0" again, and the state changes from the uppercase shift designation state to the lowercase shift designation state again!1JE1'-J
To: 4 move. Therefore, when the operator presses the alphabet keys indicating the alphabetic characters "I(1)J" in the previous VI, the second and subsequent alphabetic characters 1'-L16, "N1" are pressed.

J, roj*rtJ, and rnJ are input in order. In addition, for the space key and blank key temple's masterpiece to create a space between the first letter "I" and the second letter [, etc. .

In this way, according to this embodiment, when a period indicating the end of one sentence is input, an uppercase shift is specified, and the uppercase shift is specified in the 6th sentence, i.e., the beginning of the next sentence. Since lowercase shift is automatically specified when a character is entered manually, English text can be input without operating the uppercase/lowercase shift key.

By the way, in English human power, ′ is the above-mentioned [1live
In some cases, like in Yokobama and J, manual labor is required for capital letters in addition to the capital letters in one sentence. In this embodiment, such a case can be dealt with by using the shift key operation in conjunction with the conventional example. That is, the operator

Press both the lowercase shift key and the alphabetic key indicating the alphabetic character [Y (y) J] together. Due to this, the uppercase/lowercase letter shift key operation signal B becomes logic "1", and the uppercase/lowercase letter shift designation signal A output from 0R30 becomes logic "1". As a result, the uppercase shift is specified and the uppercase letter "Y" is entered manually. In this embodiment, if the uppercase/lowercase shift key is not operated together with the lock key (not shown), it is valid only during the key operation. Therefore, when the above key operation is completed, that is, when the operator stops pressing the uppercase/lowercase letter shift key, the uppercase/lowercase letter shift key operation signal B becomes logic "O" again, and the uppercase/lowercase letter shift designation signal is output from ORJθ. A becomes logic "0" again. Therefore, alphabetic characters input manually from now on will be lowercase letters until a period is input next (unless the uppercase/lowercase shift key is operated). In addition, if you want to manually press the key ``C'', press the key ``D'' → the key is the capital letter /
All you have to do is operate all the lock keys together with the lowercase shift key, lock the uppercase shift designation state, and then operate all the alphabet keys.

In addition, in this embodiment, the uppercase shift is automatically specified after inputting the period mentioned above, and the next uppercase <) I I-f
: -r' Q h'f P-F There is also a manual mode where you can specify shifts by operating the uppercase/lowercase shift key as in the past, in addition to the manual mode.
It is now possible to select W. That is, when the mode changeover switch fSW is switched to the contact C2 side, the ANDIO gate is closed. As a result, the period signal P generated in response to the period input is passed to the F/F via AND10f.
2o set person potash, 'mlml child feeding is overpressure. For this reason, F/F20 maintains a clear state, and the uppercase/lowercase letter shift designation signal A output from 0R30 is only the uppercase/lowercase letter shift key operation signal B.
That is, it is determined only by the key operation state of the uppercase/lowercase shift key. In this manual mode, manual input of only uppercase letters is possible, for example.

〔Effect of the invention〕

As detailed above, according to the present invention, an uppercase shift is automatically specified after a period is input, and a lowercase shift is automatically specified after an uppercase character is input based on the specification of parentheses. The workability of inputting a sentence in which a character is an uppercase character, the second and subsequent characters are lowercase, and the last character is a period is significantly improved, and input errors are reduced.
