Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an improvement of a typewriter that can print characters and Braille at the same time, and in particular, to improve a typewriter that can print characters and Braille at the same time. The present invention relates to a method for simultaneously printing characters and Braille using a printing code conversion method, and a typewriter that implements this method.

[Conventional technology and its problems]

2. Description of the Related Art Conventionally, various types of typewriters have been proposed that simultaneously print characters and Braille corresponding to the characters by a common key operation. However, in Braille, when marking a voiced sound, a semi-voiced sound, a persistent sound, a number, a symbol, etc., a code consisting of a combination of six dots is added and placed before the main code. For this reason, for example, when printing characters that include voiced sounds or persistent sounds, the content of the characters cannot be determined unless the type keys are operated phonetically. Not only does it take time to convert the characters and Braille printing code, There is an inconvenience that the timing of printing is delayed and confirmation cannot be made quickly.

Therefore, in this type of typewriter, when operating a character key, the corresponding character is printed quickly for each key operation, and even braille can be reliably printed in a predetermined format even if there is a delay in one key operation. It is desirable to have a configuration that allows this.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a typewriter with a function of printing characters and Braille at the same time.
When printing characters and braille by operating character keys, characters are printed at the same timing by operating the character keys in the normal stroke order, while braille is printed at the same timing by delaying one key operation. To provide a simultaneous character/braille printing method capable of converting a printing code so as to print in a different format and making it easier to check the printing state, and to provide a typewriter for carrying out the method.

[Means to solve the problem]

The simultaneous character/braille printing method according to the present invention is a simultaneous character/braille printing method that has a function of simultaneously printing corresponding characters and braille by a common key operation. The mechanism converts the character code and prints it, and the Braille code conversion mechanism converts the character selected by the character key operation to the Braille code, and also distinguishes between special marks.If it is a special mark, it is printed in Braille; If it is a Braille code other than the special mark, it is temporarily stored in the memory, and if it is other than the special mark, it is determined whether or not there is a Braille code already temporarily stored in the memory, and if it is temporarily stored, it is printed, and then the special mark is printed. It is characterized by temporarily storing Braille codes other than the above.

In addition, a simultaneous character/braille printing typewriter that implements the above method is a simultaneous character/braille printing typewriter that has a function of simultaneously printing corresponding characters and braille by a common key operation. At the same time, a character code conversion mechanism includes a character code conversion means for converting character codes and a character printing means for printing characters from the converted character codes, and a Braille code for converting characters selected by character key operations into Braille codes. a converting means, a first determining means for determining whether the converted Braille code is a special mark, a Braille printing means for performing Braille printing on the Braille code determined to be a special mark by the first determining means; a second determining means for determining whether or not there is a Braille code temporarily stored in the memory when the determining means determines that the Braille code is other than a special mark; means for printing braille by the braille printing means for the braille code that is present, and for temporarily storing in a memory the braille code other than the special mark discriminated by the first discriminating means, and temporarily storing in the memory by the second discriminating means. When it is determined that the
The present invention is characterized in that a Braille code converting mechanism is provided, which includes means for immediately temporarily storing in a memory the Braille code other than the special mark determined by the determining means.

In addition, in the present invention, when printing characters and Braille simultaneously, the special marks recognized by the Braille code conversion mechanism are diacritic notes, semi-voiced notes, sulky notes, sulky notes, diacritical notes, long notes, special notes, and dakudaku notes. musical notes, shuhandaku notes,
Set number marks, external characters, etc.

[Effect]

According to the present invention, when printing characters and Braille with voiced sounds, semi-voiced sounds, etc., when the clear sound character key is operated, the characters are printed immediately, while the Braille characters are temporarily stored, and then the voiced sounds etc. When the character key is operated, the characters are printed in the same way as above, and for Braille, only the voiced sounds etc. are printed, and when the next character key is operated, the temporarily memorized clear sound of the Braille is printed. By configuring the apparatus to do so, characters can always be printed prior to Braille each time a character key is operated, making it easier to confirm printing operations and improving accurate typing operations.

〔Example〕

Next, the method for simultaneously printing characters and Braille according to the present invention will be described in detail below with reference to the accompanying drawings in relation to a typewriter that implements this method.

FIG. 1 is a block circuit diagram of a typewriter of the present invention, which includes a character code conversion mechanism and a Braille code conversion mechanism as main parts. That is, in FIG. 1, reference numeral 10 indicates a keyboard as an input device, and signals obtained by key operations on this keyboard 10 are input to a character code converter 12 and a Braille code converter 14, respectively. Ru. Next, the character code and Braille code converted by the character code converter 12 and the Braille code converter 14 are symmetrically printed at a predetermined timing by the separately provided character printer 16 and Braille printer 18, respectively. In this case, the character printer may be of the well-known dot impact type, and the braille printer may suitably be of the well-known solenoid-driven six-dot marking type.

However, in the present invention, the keyboard 10
When converting into character code and Braille code by key operation in , character code converter 12 and Braille code converter 12 and Braille code converter This is characterized by an improved code conversion method in the converter 14.

FIG. 2 is a flowchart showing the operation of the code conversion method in the character code converter 12 and the character code converter 14 described above. That is, according to the present invention, the signal obtained by the first key operation is simultaneously subjected to character code conversion and Braille code conversion. The character code obtained by character code conversion is immediately transferred to a character printer serving as character printing means, and predetermined characters are printed. On the other hand, the Braille code obtained by converting the Braille code is
The first determining means determines whether the code is a code of a syllable note, a special note, a number note, a non-standard note, etc.). In this case, the braille code obtained by the first key operation is usually a kihon note, and if it is a kihon note code, it is configured to be temporarily stored in the memory. That is, when it is determined that the Braille code obtained by converting the Braille code is not a special mark code, the second determining means determines whether there is a Braille code temporarily stored in the memory, and determines whether or not there is a Braille code temporarily stored in the memory. If there is no Braille code, it will be temporarily stored immediately.

Next, when the second key operation is performed, character code conversion and braille code conversion are performed in the same way as above, and the character code obtained by character code conversion is immediately transferred to the character printer and printed as the predetermined character. is printed. On the other hand, the Braille obtained by converting the Braille code is determined by the first determining means as to whether it is a special code. In this case, if the Braille code input by operating the second key is a special sign, it is immediately transferred to the Braille printer and a predetermined Braille code is printed. At this time, the temporarily stored Braille code (quiet note) generated by the first key operation is stored and not printed.

Thereafter, when the third key operation is performed, the predetermined character code is immediately printed in the same manner as described above, and the Braille code is determined by the first determining means as to whether it is a special mark code or not. If it is not a special mark,
Furthermore, it is determined by the second determining means whether there is a Braille code temporarily stored in the memory, and the Braille code (Kiyonen) created by the first key operation that was temporarily stored earlier is changed to After confirming that the Braille code (special mark) has been printed, it will be printed.
The non-special Braille code is temporarily stored in memory. In addition, in the same way, if the Braille code of the Kiyone note is consecutive, the second determination means determines that the Braille code is temporarily stored in the memory, and this temporarily stored Braille code is printed in Braille. At the same time, the next Braille code is temporarily stored in the memory in sequence.

As described above, according to the code conversion method according to the present invention, character codes are printed immediately with each key operation, and braille codes are configured to wait for the input of a special mark and then print sequentially from that point on, so that the printing state can be changed. Confirmation is facilitated and typing operations are further simplified.

Next, a specific example of operation using the character/braille simultaneous printing typewriter according to the present invention, which employs the above-described printing code conversion method, will be described.

FIG. 3 shows an example of the character "ba" having a voiced sound and printed in Braille. If you select "Ha" with K1 in the first key operation, the character printer will immediately select "Ha".
However, the Braille printer does not print anything. Next, when "〓" is selected with the second key operation K2, the character printer immediately prints "〓" and synthesizes "ba". On the other hand, at the time of , the character printer prints the special mark ``-- ‐・ ‐-''. after that,
When another character is selected with the third key operation K3, the Braille printer prints a clear note ".----." which corresponds to the "ha" selected with the first key operation K1. Note that characters consisting of semi-voiced sounds, persistent sounds, rasp sounds, consonants, long sounds, etc. can also be processed in the same manner as in the example shown in FIG.

FIG. 4 shows an example of printing the character "Gua" with a special sound and Braille. If you select "ku" with the first key operation K1, the character printer will immediately select "ku".
However, the Braille printer does not print anything.
Next, when "〓" is selected by the second key operation K2, the character printer immediately prints "〓" and synthesizes "gu". On the other hand, at this point, the character printer prints the special mark ``----・--''. Thereafter, when the special note "a" is selected by the third key operation K3, the character printer immediately prints "a" and synthesizes "gua". On the other hand, the Braille printer converts the special note ``-- ・- ‐-'' into the voiced note ``-- ‐・ ‐‐''.
Overlay it to synthesize "-- . . . -.". Then, by selecting another character with the fourth key operation K4, the Braille printer prints the clear note "・- ‐ - ‐・" corresponding to the "ku" selected with the first key operation K1. (in this case, it is changed to "ka") is printed. In addition,
As for the characters consisting of undakuten notes, tsukuhandakuon, etc.
Processing can be performed in the same manner as the example shown in FIG.

FIG. 5 shows an example of printing the number "1" in characters and Braille. First, operate the shift key to select a number. Next, the first key operation K
When "1" is selected in 1, the character printer immediately prints "1" and the braille printer prints the special numeric character "------". Then, by selecting another character with the second key operation K2,
The Braille printer prints the numeral mark ".-----" corresponding to "1" selected by the first key operation K1. Note that external characters and other symbols can also be processed in the same way as the example shown in FIG.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and within the scope of the spirit of the present invention,
Of course, various design changes can be made.

〔Effect of the invention〕

As is clear from the embodiments described above, according to the present invention, character codes are printed immediately upon each key operation, while Braille codes wait for the input of a special mark and are printed sequentially from that point on, starting with the special mark. This can be achieved appropriately and easily based on a predetermined program, and it is possible to provide a typewriter with a simultaneous character and braille printing method with excellent operability and a simple configuration at a low cost.
