Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer, and more particularly to a printer in an electronic typewriter, a word processor, etc., in which a replaceable type member such as a type wheel is used. More particularly, it relates to a printer having means for checking misspellings of input words called spell checking.

[Prior Art] In a printer such as an electronic typewriter or a word processor, a type member (hereinafter referred to as a type element) is generally different depending on a destination. The type element as shown in the figure, and in the French specification, the type element as shown in FIG. 5B is arranged on the daisy wheel W2.

As can be seen from FIGS. 5A and 5B, the German wheel W1 has no type such as "" or "" located on the wheel W2, and the French wheel W2 has no wheels. “” Located in W1
There is no typeface such as or.

Therefore, when printing a language of another country different from the specifications of the country, it is customary to replace the wheel.

In recent years, printers of this type have also been equipped with a means called spell check for checking misspellings of words. Such spell check has a dictionary corresponding to the language, and accesses the dictionary every time a word is input and checks whether or not the word exists. When a French wheel is installed in a German printer with a built-in computer and French is entered, most of the words do not exist in the German dictionary and are treated as errors, which is extremely useful for operators who use multiple languages. It had the drawback of being inconvenient to use.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to replace a printing member and select a multilingual operator in any language. Is to provide a printer that can check spelling.

[Means for Solving the Problems] In order to achieve such an object, the present invention has a plurality of print characters for each language, a replaceable print member, and a language by print characters input by the replaced print member. And a dictionary for checking the misspelling of each type by language, and having a discriminating means for discriminating the type of the type member, and a selecting means for selecting a dictionary based on the discrimination result of the discriminating means. is there.

[Operation] The printer of the present invention is provided with a dictionary for spell check for languages of a plurality of types of countries, and when a type member is exchanged, a dictionary corresponding to the language-specific specifications of the exchanged type member is used. Since the spell check is performed, it is possible to provide a printer that is extremely easy to use for an operator who handles multiple languages.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1A shows an embodiment according to the present invention, in which 1 is a central processing unit CPU that controls overall control, 2 is a keyboard, and 3 is a keyboard.
Is a printer, and 4 is a sensor SEN capable of discriminating the wheel-specific specifications as will be described later. Further, 5 is a switch SW for detecting the opening / closing of the hood that is opened / closed when the wheel is exchanged, 6 is a coded micro instruction information for sequential control by the CPU 1, and stores a program described later based on FIG. Read-only memory ROM, 7 is a random access memory RAM for storing input documents, and CPU 1 is a memory for reading and writing, and 8 is a language dictionary D1 for a plurality of countries for spell checking. , D2, D3, ..., Dn are stored in the dictionary section of the read-only memory, and 13 is an alarm.

FIG. 1B shows the keyboard 2 in more detail, where 21 is a key arranged on the keyboard 2, and in this example, a character key for designating the character “A”. In most devices, such a key 21 is arranged in a form deviated from the grid, but its signal wiring is formed in a key matrix as shown in the figure.

Thus, the information of the pressed character key 21 is detected through the key matrix 22, and the information signal from this key matrix 22 is supplied to the KE, key encoder 29 and coded.

Subsequently, the configuration of the type wheel and the wheel type detection means will be described with reference to FIGS. 2A and 2B.

Here, the type wheel 10 is entirely formed of a flexible material such as plastic, a plurality of spokes 10A are radially provided on the outer periphery of the circular rim, and the type 10B is further provided at the tip of the spoke 10A. Are integrally formed.
A black tape 10C that does not reflect light is attached to the rim of the type wheel 10. Then, this black tape 10C
Has white parts 10D at intervals so that a predetermined angle α set according to the country specification of the type wheel is maintained, and the relationship between this angle α and the country specification of the type wheel. Are set as shown in Table 1 below.

That is, in this example, the position where the white portion 10D is formed is the angle 3
It is set in increments of 0 degrees for each country specification, and the white part 10D reflects the light emitted from the sensor light source 4A as shown in FIG. It can be read by element 4B. This table of angle-specific specifications for each country is stored in ROM6 as digital information, and based on this information, CPU1
Can detect the country-specific specifications of the print wheel.

Next, the mounting structure of the hood switch SW5 is shown in FIG.
In this example, the keyboard 2 is provided on the surface inclined toward the operator, and further the platen 31 is provided in the case 30.
A movable type carriage 32 is housed in a position opposite to the platen 31, and a type wheel mounted on the carriage 32.
When replacing the 10, the hood 34 must be opened. Reference numeral 35 denotes a protrusion provided on the tip of the hood 34, and when the hood 34 is pulled back to the closed position, the protrusion 35
By this, the switch SW5 is turned "on", and SW5 is turned "off" at the open position shown in the figure.

Next, the spell check operation performed by the printer thus configured will be described in detail with reference to FIG.

First, when the power of the entire device is turned on, in step S1, the CPU 1 determines whether or not SW5 is on, and if it is off, that is, if it is open, waits until the hood 34 is closed and proceeds to step S2. Then, in step S2, the type wheel 10 is rotated, the angle α of the white portion 10D of the black tape 10C is detected through the sensor 4, and in step S3 the conversion table in the ROM 6 is referenced to convert to country-specific information. Then, this country-specific information is stored in the address WHSTS in the RAM 7 in step S4.

Thus, in the next step S5, it is determined whether or not the dictionary of the language corresponding to the country-specific information is selected, and in the next step S6, the key input is performed. If a key is input here, the process proceeds to step S7, the input code is stored in the document buffer, the printer is activated in step S8, and the operation corresponding to the input code, for example, if a character is input, printing is performed. In the next step S9, it is determined whether or not the input code is a code indicating a word delimiter such as a space, period, or return. If it is a word delimiter, the process proceeds to step S10 and is stored in the document buffer. It is determined whether or not the last stored word is present in the dictionary selected in step S5, and if not, an alarm is sounded in step S11 to notify the operator that the word is misspelled, then In step S12, check whether SW5 is on or off.If it is on or closed, return to step S6.If it is off or open, return to step S1 and close. Wait until it is. If no key input is made in step S6, or if the word is not separated in step S9, and if the input word exists in the dictionary in step S10, skip each intermediate step and skip step S12. Proceed to.

As is clear from the above explanation, by allowing the operator to select a dictionary corresponding to the country-specific specifications of the print wheel each time the print wheel is replaced, a printer that can always check spelling corresponding to the input language is selected. It has become possible.

In the above description, an alarm is used as a means for informing the operator that the misspelling has occurred, but any device having a display means may be displayed on the display to inform the operator.

[Effects of the Invention] As described above, according to the present invention, spell-check dictionaries for each country are provided corresponding to the language-specific specifications of print members, and when the operator replaces the print members, they are replaced. Since the dictionary of the language corresponding to the language specification of the type member is used for spell check, the operator only needs to replace the type member to be aware of the language in which the spell check is performed. It is not necessary, and since the dictionary to be accessed is only one language, it is possible to realize a printer that is easy to use and can achieve the same speed as conventional spell checking.
