Claims (1)

[Claims for Utility Model Registration] A coordinate reading circuit that takes in graphic information processing commands and coordinate information, a menu setting memory in which basic processing commands are registered in advance, and a macro command selection switch provided on the pointing device. A data decoder circuit that analyzes signals, a stack memory that stores a continuous group of execution commands, a stack control circuit, an arithmetic circuit that compares and performs arithmetic processing on data from the coordinate reading circuit, an address decoder that determines the execution timing of processing, and a specification The graphics processing device consists of a command processing device that sequentially executes commands, a display for displaying graphics, and a pointing device for specifying coordinates, in which basic commands for graphics processing are registered in advance. When inputting various graphical information, by combining the basic commands and assigning them as one macro command to one button on the pointing device, the operator can simply specify coordinate information and press the macro command button. A graphics processing device that is characterized by being provided with a means for efficiently inputting graphic information by making it possible to specify complex operations.
