Abstract

PURPOSE: To economize the memory and make it inexpensive, by controlling the character pattern generator memory so that a character pattern for the maximum number of characters which are required for display of one picture can be registered.
CONSTITUTION: A Chinese character code which is received from the terminal control equipment TCE, is stored and is registered in the external buffer 1 is converted to the address of the internal character pattern generator CG, and it is registered in the internal buffer 2. The external code is converted to the internal code by the microprocessor 15. the CG memory 3 stores a character pattern, has the memory capacity corresponding to the maximum number of characters displayed on one picture of the indicator, and stores the character pattern corresponding to the maximum number of characters, therefore the capacity itself can be economized, but since the contents to be displayed are changed one after another, the character pattern is changed by the processor 15. Therefore, the table 6 controls that a character pattern corresponding to the Chinese character code is registered in the memory 3. Since the table 7 controls the CG address which is being used for display, the register 8 is provided, and also the register 7 is provided for detecting an unnecessary CG address.
