2. Description of the Related Art Conventionally, in an image processing apparatus typified by a facsimile, a character displayed as a message on a display panel is encoded by an ASCII code or the like and stored in a read memory of a control unit. When a signal is sent from the control unit to the reading memory, it is judged in the reading memory which message the signal corresponds to, and the code of the required message is taken out and transferred to the display unit serially or in parallel. Further, it was displayed on the display panel connected to the display section.

[0003]

However, some image processing apparatuses such as facsimiles are used in several countries or more. Therefore, in order to make it usable in all the countries of use, the coded data of the characters of the message shown in the language of the country of use must be stored in the read memory, which is why the capacity of the read memory is large. There was a problem that it had to be enormous.

Further, since it is used in a plurality of countries, even if the signal transmitted from the main control unit to the read memory is the same, the number of characters of the displayed message will be different if the country used is different, and the main control unit will be different. In some cases, the length of the data corresponding to the number of characters transferred from the display to the display changed. Therefore, when transferring data from the main control unit to the display unit, for example, after transferring the type of data, the length of the data is transferred each time, and finally the data of the actual character is transferred. Data must be transferred,
There is a problem that the process becomes complicated in the process of displaying the message determined in the read memory on the display panel of the display unit.

[0005]

In order to solve the above-mentioned problems, the invention of claim 1 is an image processing apparatus comprising an image processing apparatus, comprising a main control section and a display section, wherein the main control section displays the image. It is characterized in that data indicating the contents is transferred to the display unit, and the display unit converts the transferred data into a character code and displays it.

According to the second aspect of the present invention, the main control unit includes a main read memory, and the data indicating the display contents is stored as data of a fixed length in the main read memory. The control unit reads the data according to the state of the device and transfers it to the display unit, and the display unit has an auxiliary read memory, and the character code is read from the auxiliary read memory according to the data from the main control unit. Is generated.

Further, the invention of claim 3 is characterized in that the auxiliary reading memory stores an area for storing a character code for one kind of language and a bit pattern corresponding to the character code.

[0008]

Therefore, according to the invention of claim 1, since the character code is generated in the display section, it is not necessary to store all the character codes corresponding to each language in the read memory of the main control section.
The capacity of the read memory can be reduced.

Further, according to the second aspect of the present invention, all the messages stored in the auxiliary read memory corresponding to the data of a fixed length transmitted from the main control section are character codes indicating the display contents. Therefore, it is not necessary to transfer the length of the code data when transferring the data from the main control unit to the display unit, and the message output from the reading memory is displayed on the display panel of the display unit. The process up to displaying is simplified.

Further, according to the invention of claim 3, since only the character code of the language of the country of use is stored and the auxiliary read memory for storing the bit pattern corresponding to the character code is used, the amount of the stored character code is increased. It can be prevented.
