Abstract
PURPOSE: To economize the capacity of a memory, by preparing normal, white removing, double and partial white removing pattern data from one dot pattern data stored in the dot matrix memory and a control pattern data, and making it unnecessary to store various data in the memory.
CONSTITUTION: A dot matrix data is read out from the dot matrix memory 1, it is provided to the control pattern data memory circuit 2, and at the same time it is provided to the logic negating circuit 3, the OR circuit 4, the exclusive "or" circuit 5 and the pattern selective circuit 6. And logic negation of the matrix data, OR of the control pattern data and the matrix data, and exclusive "or" of the matrix data and the pattern data are generated, and the matrix data, logic negation, OR and exclusive "or" are selected by the selective circuit 6 and are output so that normal, white removing, double and partial white removing pattern data can be prepared, and the capacity of the memory 1 is economized.
