ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention generally relates to business nonstandard character processing apparatuses and systems and computer readable storage mediums, and more particularly to a business nonstandard character processing apparatus and system which process nonstandard characters for each work which are not predefined, and are suited for application to a computer which is coupled to a network and carries out a plurality of works, and to a computer readable storage medium which stores programs for processing nonstandard characters for each work which are not predefined.
Normally, a character set and a code set which are predefined by a standard or the like when processing characters in a computer. The character set is a set of characters which are processed, and the code set is a set of characters and numbers or character codes assigned to the characters.
A provider of a computer hardware or a provider of an operating system which controls the computer usually provide character fonts in the form of a font random access memory (ROM) or a font file by using some kind of character code as the precondition.
When processing a character which is not defined by the character set, the user of the computer creates his own character font and stores this character font in a file. By registering this file as a nonstandard character file, it becomes possible to use a character which is not defined by the standard.
The need to register nonstandard characters is small in the case of a large computer which is originally designed to process a large number of kinds of characters. For this reason, the number of registrable nonstandard characters does not become a problem in the large computer, and a single large computer can simultaneously process various works.
But recently, the performance of small computers has improved considerably, and there are now demands to carry out on a small computer, such as a personal computer, the work that is conventionally carried out by the large computer. However, in the small computer such as the personal computer, the number of kinds of characters that can be processed is small to start with, and the number of registrable nonstandard characters is not sufficient to enable the small computer to carry out the word of the large computer. For this reason, the small computer can only carry out limited work, and when carrying out a plurality of works on the small computer, the work must be limited to the work that does not process the nonstandard characters.
Furthermore, there are demands to process various kinds of works by connecting the small computer such as the personal computer to a network, and consequently, there are demands to realize a technique for efficiently processing a large amount of nonstandard characters.
SUMMARY OF THE INVENTION
Accordingly, it is a general object of the present invention to provide a novel and useful business nonstandard character processing apparatus in which the problems described above are eliminated.
Another and more specific object of the present invention is to provide a business nonstandard character processing apparatus which assigns work identification information for each work that is processed on a computer, and manges nonstandard character files depending on each work identification information. When transmitting a nonstandard character file from a server which manages the nonstandard characters to a server which carries out the work, only a difference between a previously transmitted nonstandard character file and the present nonstandard character file which is to be transmitted is transmitted, so as to reduce a load on the network.
Still another object of the present invention is to provide a business nonstandard character processing apparatus comprising a plurality of work processing parts carrying out processes using nonstandard character data registered in a system nonstandard character file, one or a plurality of nonstandard character files provided correspondence with work identification information, and a nonstandard character registration processing part registering as the nonstandard character file a nonstandard character file provided in correspondence with a specified work identification information. According to the business nonstandard character processing apparatus of the present invention, it is simply necessary to set up a nonstandard character registration program in a client apparatus, and thereafter, it is possible to correctly display the most recent nonstandard character for each work, without having to be conscious of the nonstandard characters. In addition, since it is possible to switch and use the nonstandard characters for each work, it is essentially possible to use an infinite number of nonstandard characters. Furthermore, because the nonstandard characters need not be registered for each client apparatus, the operation efficiency and operation ease of the client apparatus are improved with respect to the operator who operates the client apparatus. In addition, the load on the network can be reduced by checking the updating of the nonstandard character file and by using the difference nonstandard character transmission file.
A further object of the present invention is to provide a business nonstandard character processing apparatus coupled to a nonstandard character management server apparatus which provides a whole nonstandard character transmission file, a difference nonstandard character transmission file and a distribution management information file, where the whole nonstandard character transmission file stores all of most recent nonstandard character information, the difference nonstandard character transmission file stores a difference of nonstandard character information of one generation before and the most recent nonstandard character information, the distribution management information file stores dates of the most recent nonstandard character information and the nonstandard character information of one generation before, and the business nonstandard character processing apparatus comprises a nonstandard character file provided within the business nonstandard character processing apparatus, and means for updating the nonstandard character file within the business nonstandard character processing apparatus using one of the whole nonstandard character transmission file and the difference nonstandard character transmission file, based on a comparison result of a date of the nonstandard character file within the business nonstandard character processing apparatus and a date stored in the distribution management information file within the nonstandard character management server. According to the business nonstandard character processing apparatus of the present invention, it is simply necessary to set up a nonstandard character registration program in a client apparatus, and thereafter, it is possible to correctly display the most recent nonstandard character for each work, without having to be conscious of the nonstandard characters. In addition, since it is possible to switch and use the nonstandard characters for each work, it is essentially possible to use an infinite number of nonstandard characters. Furthermore, because the nonstandard characters need not be registered for each client apparatus, the operation efficiency and operation ease of the client apparatus are improved with respect to the operator who operates the client apparatus. In addition, the load on the network can be reduced by checking the updating of the nonstandard character file and by using the difference nonstandard character transmission file.
Another object of the present invention is to provide a business nonstandard character processing apparatus coupled to a nonstandard character management server which provides a nonstandard character transmission file and a distribution management information file, where the nonstandard transmission file stores most recent nonstandard character information, the distribution management information file stores a date of the most recent nonstand
