The document data desired by the user is created in accordance with the operation of the character / symbol input key 13 and the numerical value input key 14 on the key input unit 11 and stored in the document data memory 33a in the RAM 33. In order to convert the unit symbol described in the non-SI unit system and the numerical value with the unit symbol in the document data stored in the memory 33a into the SI unit system and describe it, the “unit conversion” key 19 is used. When operated, the unit conversion process in FIG. 5 is started.

When the unit conversion process is started, first,
It is determined whether or not the document data to be subjected to the unit conversion processing is stored in the document data memory 33a. If it is determined that the target document data is stored, as shown in FIG. In the “Batch conversion mode” that performs batch processing for all unit symbols in the document, or
Alternatively, a conversion mode setting screen G1 for setting by user selection whether to execute in the “individual selection conversion mode” in which individual unit symbols are individually selected is displayed on the liquid crystal display unit 12.
(Step S1 → S2).

In this conversion mode setting screen G1,
When "1. Batch conversion" or "2. Individual selection conversion" is selected by operating "1" or "2" of the ten keys 14, "1.
When "Batch conversion" is selected, the batch conversion mode flag F = 0 is set, and when "2. Individual selection conversion" is selected, the individual selection conversion mode flag F = 1 is set in the conversion mode memory 33b in the RAM 33. Is set, and the batch conversion mode or the individual selection conversion mode according to the user selection is set (step S3 → S4).

The counter data K stored in the unit counter 33c for sequentially specifying various unit symbols of the non-SI unit system stored in the unit symbol conversion table 32a (see FIG. 3) in the ROM 32 is used. It is set to "1" (step S5).

Then, first, the non-SI unit symbol "f" in the unit symbol conversion table 32a specified by the counter data K (= 1) set in the unit counter 33c.
The search for "t" is performed from the beginning of the document data stored in the document data memory 32a, and it is determined whether there is a corresponding non-SI unit symbol "ft" (steps S6 and S7). At this time, the search state of the non-SI unit symbol for the document data is displayed on the liquid crystal display unit 12 on the monitor, and when the corresponding non-SI unit symbol is searched, the symbol and the numerical value range to which the symbol is attached are highlighted. Shown.

Here, when the first non-SI unit symbol "ft" is retrieved from the document data, the conversion mode flag F set in the conversion mode memory 33b is changed to the batch conversion mode flag F = 0. Or whether the individual conversion mode flag F = 1 is determined (step S7 → S
8).

When it is determined that F = 0, that is, the batch conversion mode is set, the non-SI unit symbol "ft" retrieved from the document is immediately converted to the unit symbol conversion table 32a. Is converted to the corresponding SI unit symbol “m” (step S8 → S
9).

At the same time, a numerical value (for example, 10) with a non-SI unit symbol “ft” retrieved from the document is added.
[Ft]) is numerically calculated according to the conversion coefficient “0.3048” specified by the counter data K (= 1) stored in the conversion coefficient table 32b,
In this case, it is converted to 3.048 [m] (step S1).
0, S11). At this time, the unit conversion result data [1]
0ft → 3.048m] is stored in the conversion history memory 33d.

On the other hand, if it is determined in step S8 that the conversion mode flag F set in the conversion mode memory 33b is F = 1, that is, the individual selection conversion mode is set, the process proceeds to step S6. , S7, a conversion presence / absence selection screen G2 is displayed as shown in FIG. 7 for the user to select whether or not to perform unit conversion on the non-SI unit symbol and its numerical value retrieved and displayed from the document (step S8). → S14).

On this conversion presence / absence selection screen G2,
When "1. Yes" is selected by operating "1" on the numeric keypad 14, the non-SI unit symbol retrieved from the document is converted to the SI unit symbol associated in the unit symbol conversion table 32a ( Steps S15 → S9), and at the same time, the numerical value with the searched non-SI unit symbol is numerically calculated according to the conversion coefficient specified by the counter data K stored in the conversion coefficient table 32b. (Step S10,
S11).

That is, when the individual selection conversion mode (F = 1) is set, every time a non-SI unit symbol specified by the counter data K is retrieved from the document, the conversion presence / absence center screen G2 is displayed. Is displayed to prompt the user to select “1. Perform” or “2. Do not perform” the conversion to the SI unit. If “1. Perform” is selected, the non- Conversion of SI unit symbols and numerical values to SI units is performed.

Thus, for the first non-SI unit symbol "ft" stored in the unit symbol conversion table 32a specified by the counter data K = 1, the first identical symbol "ft" from the document data is In the batch conversion mode, the search is performed and steps S7 to S11 are performed. In the individual selection conversion mode, steps S7, S8 → S14, S1 are performed.
5 → S9 through S11, and the corresponding SI
When converted to the unit "m", it is determined whether the search position for the document data has reached the end of the sentence (step S).
12) If it is determined that the sentence is not the end of the sentence, the search for the first non-SI unit symbol “ft” is continued toward the end of the sentence (step S12 → S13), and the processing from step S7 is repeated.

Thereafter, the processes of steps S7 to S13 are repeated in the batch conversion mode, and the processes of steps S7 to S15 are repeated in the individual selection conversion mode. The search for the first non-SI unit symbol “ft” stored in the conversion table 32a and the numerical value to which the symbol is assigned, and the conversion to the corresponding SI unit “m” are performed collectively or individually. If it is determined that the search position has reached the end of the sentence,
The counter data K stored in the unit counter 33c
Is counted up and set to “2” (step S12 → S16).

If it is determined that the counter data K does not exceed the maximum number n of each unit in the unit symbol conversion table 32a, the process returns from the step S6 (step S17 → S6), and the counter Data K = 2
The second non-SI unit symbol “OZ” specified by the above and the search of the numerical value with the symbol from the beginning of the document data and the conversion process to the corresponding SI unit “kg” are set in the conversion mode memory 33b. Depending on the conversion mode flag F = 0 or F = 1, the conversion is performed by either batch conversion by repeating steps S7 to S13 or individual selection conversion by repeating steps S7 to S15.

That is, for each of the non-SI unit symbols specified by the counter data K, the search over the entire range of the document data and the conversion process to the SI unit are repeatedly performed, and thereafter, step S16 When the counter data K stored in the unit counter 33c is counted up and it is determined that the counter data K exceeds the maximum number n of each unit in the unit symbol conversion table 32a, the series of unit conversions is performed. With the processing, the result data of each unit conversion from the non-SI unit to the SI unit in the document data is read out from the conversion history memory 33d, and as shown in FIG. (Step S17 → S1)
8).

When it is desired to print out the document data stored in the document data memory 33a,
By operating the "print" key 18, the document data is converted into a character pattern constituting each character, written into the print data memory 33f, output from the printer control unit 37 to the printer 36, and printed.

Therefore, according to the unit conversion function for the created document in the word processor having the above configuration,
Non-SI in unit symbol conversion table 32a in ROM 32
The unit symbol [ft, OZ, Torr, ...] and the SI unit symbol [m, kg, Pa, ...] are stored in association with each other, and the non-SI unit symbol is stored in the document data memory 33a in the RAM 33. A unit symbol is searched from the created document data stored in the non-S
The I unit symbol is converted to the corresponding SI unit symbol, and the value in the document to which the symbol is attached is RO
Numerical conversion is performed based on the conversion coefficient corresponding to each unit stored in the conversion coefficient table 32b in M32.
Even document data created using I unit system numerical values and symbols can be easily converted and rewritten into SI unit system numerical values and symbols required in official documents and the like.

Further, according to the unit conversion function of the word processor having the above configuration, when executing the unit conversion processing,
When the batch conversion mode or the individual selection conversion mode is selected by the user on the conversion mode setting screen G1 displayed on the liquid crystal display unit 12 and the batch conversion mode is set, each of the non-SI units sequentially searched from the document is set. Symbols and numerical values are immediately converted, and the entire document is converted at once. If the individual selection conversion mode is set, each symbol and numerical value in non-SI units sequentially searched from the document is converted. The presence / absence selection screen G2 is displayed, prompting the user to select “convert” or “do not convert”, and only when “convert” is selected, the correspondence between the symbol and the numerical value of the non-SI unit being searched. Since the conversion to the SI unit is performed, the entire description of the non-SI unit system included in the document is uniformly converted to the SI unit system.
