Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an electronic typewriter that has a practice function in addition to the normal typewriter function, and particularly relates to an electronic typewriter that has a practice function in addition to the normal typewriter function. The present invention relates to an electronic typewriter that prints in highlighted character form when the case occurs.

[Prior Art] Some electronic typewriters have a built-in microcomputer and are equipped with various functions.

Normally, electronic typewriters with built-in microcomputers of this type immediately print out character data such as letters, numbers, symbols, or spaces entered from the keyboard onto printing paper set on the platen. In addition to the typewriter function, the character data entered by the key is temporarily stored in the memory section, and the memorized text is sequentially displayed on the display section provided adjacent to the keyboard, while adding to this text. After performing editing work such as , corrections, etc., the memory 9 pieces are printed out again on the printing paper set on the platen 1! It also has functions.

Furthermore, electronic typewriters having a practice function in addition to the above-mentioned functions have also been developed. In such electronic typewriters, practice text sentences are stored in advance in the memory section, and the practitioner prints out the practice text sentences while writing the same characters as the practice text sentences on the keyboard. Enter the keys in sequence. Then, the key-input character data is sequentially compared with each character data of the practice text sentence stored in the storage section.

If incorrect character data is entered from the keyboard, a short warning sound is emitted at that point. In addition, the character data entered by the practitioner using the keys, including erroneous character data, are printed out on the printing paper as they are at the time of the key entry.

If an electronic typewriter has such a practice function, if an incorrect key operation is performed, a warning sound will be emitted at that point, so that the practitioner will immediately notice the incorrect key operation.

[Problems to be Solved by the Invention] However, even with electronic typewriters having the above-mentioned practice function, the following problems still exist. That is, when a learner's skill improves to a certain extent, the speed with which he or she can accurately input each character and input all of the designated practice text l through the entire sentence becomes a problem. In this case, in addition to the key input time, the question is how many erroneous characters are present in the practice text printed out on the printing paper by the key input operation. However, searching for erroneous characters in long practice documents is not easy and requires a lot of time. In cases where there are a large number of trainees, such as in an electronic typewriter training school, it becomes extremely troublesome for the instructor to grade the printed practice documents of each trainee.

Also, if you are typing the practice sentences at a certain speed, you will not stop keying at that point even if you have learned how to use the keys, so the warning sound will not make any sense. On the contrary, it becomes extremely troublesome for practitioners.

According to the present invention, when a character different from a character in a practice text sentence is input by key, the input character is printed in the form of an emphasized character, so that the incorrect character in the practice text can be easily searched for later in the printed output style. It is an object of the present invention to provide an electronic typewriter that can greatly improve practice efficiency for both instructors and practitioners.

[Means for Solving the Problems] As shown in FIG. A text memory C for storing practice text sentences, a practice mode setting means for setting the practice mode, and each character data of the practice document and the practice text that are inputted sequentially from the keyboard when setting the practice mode. Comparison means E that sequentially compares each character data of a sentence, and emphasized print output means F that prints out the character data keyed in from the keyboard in the form of emphasized characters when the comparison means determines that the two character data do not match. and normal print output means G which prints out the character data keyed in from the keyboard in the form of normal characters when the comparing means determines that both character data match.

[For RF:] In the electronic cash register configured as described above, practice text sentences are stored in the M-type text memory of the storage section. Then, after setting it to practice mode,
Each character data of the same practice sentence as the practice text sentence is inputted sequentially from the keyboard. Then, if each character data does not match the character data of the HM text sentence at the time when the character data is key-input, the erroneous character is printed out in the form of highlighted characters. Therefore, characters for which a key is pressed incorrectly on the print-out practice text are displayed in the form of highlighted characters, so that it is possible to search for the erroneous character in between.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing the external appearance of the electronic typewriter of the embodiment. In the figure, reference numeral 1 denotes a housing, a keyboard 2 is provided on the front surface of the housing 1, and a platen for setting printing paper is provided at the upper part of the housing 1. A carriage 3, whose movement is controlled in the axial direction of the platen by a carriage motor, is movably attached to a shaft arranged parallel to the platen. This carriage is equipped with a print wheel, a print hammer, a print ribbon, motors for driving these, hammer solenoids, and the like.

The keyboard 2 includes an alphabet key and an @ key.

In addition to character keys that require carriage movement such as various symbol keys, there is also a carriage return key and a shift key.

Various function keys such as a shift lock key and a code key are arranged. Furthermore, the keyboard 2 of the housing 1
A display section 4 for displaying, for example, one line of characters input by key is attached at a position above the . Further, adjacent to this display section 4, function selection keys 5. A print control key 6 and an input designation key 7 for use in practice mode are provided.

FIG. 3 is a diagram showing the details of each key 5.6.7,
A plurality of indicator lamps 5a, 6 adjacent to each key 5.6.7 displaying each mode and status selectable with that key.
a, 7a are arranged.

When each key 5, 6.7 is pressed repeatedly, each of the above modes and states changes in order, and the display lamp 5a corresponds to the selected mode or state.

6a and 7a are lit.

For example, in the function selection key 5, there is a normal "type" mode in which the key-input characters are immediately printed out;
[Line] mode prints out characters for a line, characters for one word are input.

[Word] mode, which prints out the data at the time, [Storeco mode], which temporarily stores all character data entered by the key in the memory, [Li Collection] mode, which edits the stored character data (sentences), You can select and set the [n learning] mode for learning.

In addition, the input designation key 7 specifies the E registration J condition indicating that the text for N Akane is to be registered in the storage section in advance, and the execution state indicating that the practitioner is key inputting the practice text. can.

FIG. 4 is a block diagram showing a schematic configuration of an electronic typewriter. Reference numeral 11 in the figure is a CPLI that executes various worship processes based on various data keyed from the keyboard 2 and various control keys 5, 6, and 7.
is an RO that stores fixed data such as control programs and print wheel spoke addresses via the pass line 12.
M13. A RAM 14 for storing variable data such as character data inputted from the keyboard 2. Hammer solenoid drive circuit 16 that drives the printing hammer mounted on the carriage 3. The display section 4. The keyboard 2. It controls the motor drive control circuit 17 to which various motors are connected.

The motor drive control circuit 17 includes a paper feed mode 18 which is connected to the platen and feeds the printing paper. Move carriage 3!
Carriage motor 19. A ribbon feed motor 20° for feeding the printing ribbon and a printing wheel motor 21 for controlling the rotation of the printing wheel are connected.

In addition, as shown in FIG. 5, the RAM 14 includes a practice text memory R1 for storing practice text sentences, and a practice text memory R1 for storing each character data in the practice text memory R1 when in the [81 learning] mode. A counter R2 is formed to count successive pointers for reading. Note that this practice text memory R1 and counter R2 have the practice text memory function only when the function selection key 5 is set to [Practice 1 mode;
When set to a mode other than "Practice" mode, it has a normal document memory function.

When the electronic typewriter is powered on, the CPU 11 is programmed to execute business processing in the practice 1 mode according to the flowchart of FIG. That is, when the power is turned on and the flowchart is started, the predetermined first time! Execute IIJ setting processing. In this initial setting process, initial processing for the mode set by the function selection key 5, initial processing for the conditions set by the print control key 6, etc. are executed.

When the predetermined initial processing is completed, a key signal input from the keyboard 2 is waited for at Pl. When a key signal is input at Pl, it is confirmed at R2 that the function selection key 5 is set to the [practice] mode, and the type of the input key signal is checked.

Input key signals at R3 are alphanumeric keys and numeric keys.

If it is not a key signal of a character key that involves carriage movement such as a symbol key or space key, it is determined that it is a key signal of a function key that does not involve carriage movement.
Execute the process corresponding to that function key. Then, it returns to Pl and waits for the next key signal input. If it is a character key in R3, the process advances to R4 and the state of the input designation key 7 is checked.

At R4, if the input designation key 7 is in the [register] state, it is determined that the practice text sentence is being inputted, and the character data corresponding to the input key signal is stored in the RAM 14.
ll text memory R1. Then return to Pl.

In addition, if the input designation key 7 is not in the [register] state at R4,
If it is in the [Execution] state, it is determined that the practice text is being input by the practitioner. Then, the character data indicated by the read pointer of the counter R2 in the FJ study text memory R1 is read out. Then, the character data of the key signal input this time and the read character data are compared. If both character data match in R5, it is determined that the practitioner has operated the correct character key, and the character data is printed out on the printing paper set on the platen by the printing mechanism mounted on the carriage 3. . Thereafter, the successive pointer of counter R2 is incremented by one. Then, when it is confirmed in R6 that the read pointer has not reached the Rn character data of the practice text wording stored in the practice text memory R1, the process returns to P1 and the next key input operation is performed.

Incidentally, when the read pointer of the counter R2 reaches the selection end character data of the n practice text document at R6, the series of practice tasks using this practice text wording is completed.

If the character data keyed from the keyboard 2 and the character data read from the practice text memory R1 do not match in R5, it is determined that the practitioner operated the wrong character key. And practice text memory R1
The character data next to the character data indicated by the read pointer of counter R2 is read out. Then, the newly read character data is compared with the previous character data input from the keyboard 2.

If the two match in R6, it is determined that the practitioner skipped the correct character key to input and entered the next character key. In this case, after printing out the underline "-" for one character, the read pointer of the counter R2 is advanced by 1, and the input character is printed out. When the printout process for the input characters is completed, the successive pointer is advanced by 1, and then returns to Pl to wait for the next key signal input.

If there is no further match in R6, it is determined that two or more characters have been skipped or a completely incorrect character has been keyed in.

Then, if the input character in R7 is not a space, R8
The character data keyed in from the keyboard 2 is printed out in the form of highlighted characters. This emphasized character form refers to, for example, bold printing or shadow printing. Specifically, after printing one character, the carriage 3 is moved by a small distance, and the same character is overprinted to print the emphasized character. form is obtained.

When one character data is printed out in the emphasized character form at R8, the system waits for the next character data to be input from the keyboard 2 by operating a character key at R9. When character data is keyed in, if the character data is not space data, it is determined that it is character data within the same word, and the process returns to R8, where the character data is printed out in highlighted character form. If it is space data, it is determined that the printing output process using the highlighted character form for each character data after the incorrect character constituting one word has been completed. Then, the space character "" is printed out.

Next, in Plo, the character data indicated by the successive pointer of counter R2 in practice text memory R1 is read out. If the character data read in Pll is not space data, only the underline "-" is printed out, the successive pointer is advanced by 1, and then the process returns to Plo and reads the next character data in the practice text memory R1. put out.

Then, if the character data successively generated from the practice text memory R1 in Pll is space data, one AA R
It is determined that the successive processing of each character data that makes up the space data has been completed, and the space character "" corresponding to that space data is
Print out. Thereafter, the read pointer of the counter R2 is advanced by 1, and then the process returns to Pl.

Note that if the input character data is space data in Pl, the space character is printed out in the form of an emphasized character.

Specifically, under the space character [] there is an underline "-"
" is printed. After that, the process advances to P10 and the character data in the practice text memory R1 is read out.

When practicing using the electronic cash register configured as described above, first, prior to practicing, the function selection key 5 is set to the "practice" mode, and the input designation key 7 is used to designate the "registration" state. In that state, for example, an expert or an instructor can use the practice text sentence 22 as a model shown in FIG. 7(a).
Enter the key.

Then, the key-input practice text sentence 22 is stored in the RAM.
14 Il learning text memory R1.

When the input operation for the practice text sentence 22 is completed, the input designation key 7 is set to the [execute] state.

Then, the practitioner sequentially enters the same sentences using the keys while looking at the practice text sentences 22. As shown in FIG. 7(b), the practice text 23 actually entered by the practitioner is sequentially printed out on printing paper in response to key entry operations for each character. In this case, if each character of the practice text 23 that has been key-input matches each character of the practice text sentence 22, it is printed in a normal character form. However, if one character is mistakenly skipped in one '11 KM, the skipped part is written as an underline 24 in the II study text 23 as shown in the figure. Also, if you key in an incorrect character, all the characters between the incorrect character and the last letter of the word to which the incorrect character belongs will be changed to the emphasized character form ff! It is printed out at 25.

In this way, if the practitioner presses the wrong character key, the erroneous character on the printed practice text 23 will be printed out in the emphasized character format 25, so the instructor or practitioner can identify the erroneous part. You can easily search. Therefore, training efficiency can be greatly improved for instructors and practitioners.

Furthermore, in this embodiment, all the characters after the erroneous character of the word containing the erroneous character are printed in the emphasized character form 25, which further facilitates the task of searching for the erroneous location.

In addition, in the embodiment, not only when an incorrect character is entered using the keypad, but also when one character is skipped, an underline 24 is printed at that location, so that it is possible to further identify the incorrect location. Search becomes easier.

Further, in the embodiment, the function selection key 5 is used to select [
If a mode other than practice 1 mode is selected, the practice text memory R1 is used as a part of the general wording memory, so in order to form the practice text memory R1, the RA
There is no need to make the memory capacity of M14 particularly large.

Further, in the embodiment, the practice text sentences 22 are entered using the keyboard 2 prior to practice, but they may also be entered from an external memory such as a ROM cartridge or an IC card.

[Effects of the Invention] As explained above, according to Komei Ki, when a character whose type l name is different from a character in a practice text sentence is input by key, the input character is printed in an emphasized character form. Therefore, it is possible to later search for incorrect letters in the practice text in the printout format, thereby greatly improving the practice efficiency for both the instructor and the practitioner.
