The RAM 45 temporarily stores data sent from the keyboard 1 and the host computer 2, and stores calculation results when the microprocessor 46 recognizes handwritten characters from the tablet 3.

The microprocessor 46 controls each circuit to perform character conversion, translation, and character recognition.

Next, the operation will be explained according to the flowchart shown in FIG.

Keys on keyboard 1, e.g. alphabets rkJ, r
When aJ is pressed by the operator, the code representing that character is 1000101101011.110001
01000011J is sent as serial data to the data transfer circuit 41 of the controller 4 and stored in the RAM 45.

A character conversion request flag indicating whether or not to perform character conversion, and a translation request flag indicating whether or not to perform translation are set in the RAM 45, and the microprocessor 46 stores the character conversion request flag and the translation request together with the code. Read flag.

At this time, if the character conversion request flag is "1", character conversion will be performed, and the code will be used as the address value and RO
Access M43 and enter the contents of its character conversion dictionary, that is, the code [001001011010
10J is read out and sent to the host computer 2 as serial data via the data transfer circuit 42.

Further, if the character conversion request flag is 0'', character conversion is not performed, and in addition to the case where there is no corresponding conversion code, the output code of the keyboard 1 is sent as is to the data transfer circuit 42 and sent to the host computer 2. do.

Also, from the keyboard 1, for example, the alphabet [moo
A code representing nJ is sent, and at this time, if the translation request flag is 1", the translation dictionary in the ROM 43 is scanned,
Corresponding existence = 1,000 Japanese r code representing month 1 I' 11
101100111011J, "represents the next J" code ro0100100010001.00100101
011010J, etc. are output one after another, sent to the host computer 2 from the data transfer circuit 42, and then selected as appropriate on the host computer 2 side.

On the other hand, when a handwritten character, such as a mouth, is input from the tablet 3, that figure is matched with each pattern in the ROM 44, and the corresponding character pattern, ie, the code for "A" [00100100100010J] is read out. At this time, if there is no matching character pattern, it is determined as an "error" and the user is prompted to re-enter or enter the next character.

At this time, if the character conversion request flag or translation request flag is 1°', the conversion code or translation code is sent to the host computer 2 from the data transfer circuit 42 in the same manner as described above.

According to the embodiment, key inputs on the keyboard 1 can be arbitrarily converted or translated into characters, characters input by hand on the tablet 3 can be converted into codes and sent to the host computer 2, and this can also be converted into characters or translated as desired. Furthermore, the connection to the host computer 2 can utilize an existing keyboard interface, so the controller 4 can be powered from the host computer 2 side, and can support high-speed data transfer (e.g. 19200 baud). can be done.

Note that the types of character conversion and translation are not limited to those in the embodiment, and can be performed in various ways by changing or adding to the ROM 43.

Furthermore, recognition of handwritten characters is performed in the same way for katakana, kanji, alphabets, etc., and is not limited to pattern matching, but is also possible by Japanese order tracking, etc. In this case, the ROM 44 is used.

(Effects of the Invention) As explained above, according to the present invention, it is possible to convert handwritten characters input using a tablet into a code, and also it is possible to arbitrarily translate the code input from the tablet or keyboard and send it to the host computer. The connection to the host computer utilizes an existing keyboard interface, and therefore has the advantage that the controller 1 can be powered from the host computer and can perform high-speed data transfer.
