Abstract

Abstract An interactive graphic system is provided which introduces drawing data step by step in the form of interaction to describe figures, characters, numerical figures or the like with the aid of a microcomputer. The interactive graphic system consists of a keyboard for introducing drawing data, a plotter for recording the figures, a microcomputer, and a memory unit that are constructed as a unitary structure which features small size, reduced cost and enhanced operational performance. Further, the interactive graphic system is so constructed that application software packages can be freely exchanged to diversify the functions.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 217 words
An interactive graphic system comprising: an X-Y plotter having a recording pen supported on a recording head drivable in response to an input signal for recording lines, symbols or marks on a plotting surface; a keyboard having a plurality of function keys allotted to a variety of functions related to plotting, full keys bearing characters, numerals and symbols, and control keys for controlling said X-Y plotter; a memory for storing an operating system with a program required for controlling the execution of a drawing program and a program required for plotting graphic patterns on an interactive basis, said memory including an exchangeable storage medium for storing various forms of fundamental graphic information accessible as desired by a command entered through said keyboard; a display having a character display function for displaying characters as a guide for the inputting of graphic pattern drawing information via said keyboard and a graphic display function for displaying graphic patterns plotted; a processor for executing the program stored in said memory for plotting graphic patterns in response to information entered through said keyboard; and said X-Y plotter, said keyboard, said memory, said display, and said processor being a unitary structure for enabling said X-Y plotter to plot graphic patterns in response to information entered through said keyboard through interaction with said display.
Claim 2
Dependent Claim 217 words
An interactive graphic system comprising: an X-Y plotter having a recording pen supported on a recording head drivable in response to an input signal for recording lines, symbols or marks on a plotting surface; a keyboard having a plurality of function keys allotted to a variety of functions related to plotting, full keys bearing characters, numerals and symbols, and control keys for controlling said X-Y plotter; a memory for storing an operating system with a program required for controlling the execution of a drawing program and a program required for plotting graphic patterns on an interactive basis, said memory including an exchangeable storage medium for storing various forms of fundamental graphic information accessible as desired by a command entered through said keyboard; a display having a character display function for displaying characters as a guide for the inputting of graphic pattern drawing information via said keyboard and a graphic display function for displaying graphic patterns plotted; a processor for executing the program stored in said memory for plotting graphic patterns in response to information entered through said keyboard; and said X-Y plotter, said keyboard, said memory, said display, and said processor being a unitary structure for enabling said X-Y plotter to plot graphic patterns in response to information entered through said keyboard through interaction with said display.
Claim 3
Dependent Claim 24 words
An interactive graphic system according to claim 1, wherein said exchangeable storage medium stores a variety of application programs for changing said graphic function.
Claim 4
Dependent Claim 66 words
An interactive graphic system according to claim 1, wherein said recording head has a cursor for positioning coordinate points on said plotting surface, including means for moving said cursor in an X or Y direction by manipulating said keyboard to allow said display to display any graphic pattern of the type specified by said functions keys on said keyboard within a range designated by said cursor.
Claim 5
Dependent Claim 19 words
An interactive graphic system according to claim 1, wherein said exchangeable storage medium comprises a removable plug-in type memory.
Claim 6
Dependent Claim 58 words
An interactive graphic system according to claim 1, wherein said program contains an execution mode for executing each graphic instruction one after another, and a storage mode for drawing a graphic pattern at one time after all of a series of instructions necessary for such a graphic pattern have been entered, said modes being selected through said keyboard.
Claim 7
Dependent Claim 36 words
An interactive graphic system according to claim 1, including a standardized bus for connection to an external input unit for entering information to plot graphic patterns in response to parameters entered through said external input unit.
