Abstract
Abstract An interactive graphic system is provided for automatically recording lines, symbols or marks by inputting plotting information in a step-by-step mode in an interactive system. The systems comprise a data setter for specifying, among various predetermined graphs, a graph to be plotted and for setting plotting data concerning the graph thus specified, a plotter for providing records in association with input signals, a display for requiring the plotting data inputs, and a controller for suitably controlling the various sections. The system is formed into one unit, so that the plotter can directly plot the necessary records with plotting data given by the data setter, and that the plotting operation is simplified and the system itself is small in size and low in manufacturing cost.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
An interactive graphic system comprising: a plotting means having a recording head with a recording pen positioned therein which is adapted to be driven by input signals, said plotting means having a plotting surface for recording lines, symbols or marks applied therein by said recording pen, a keyboard including a plurality of special keys for various functions with respect to drawing a bar graph, a line graph, and a pie chart and general keys for characters, digits and symbols, a controller coupled to said keyboard for executing predetermined programs according to data from said keyboard, and display means coupled to said controller for displaying instructions having an appropriate input of necessary data for plotting in a step-by-step manner in an interactive system, whereby lines, symbols or marks can be directly recorded on said plotting surface of said plotting means by said keyboard.
Claim 2
Dependent Claim
142 words
An interactive graphic system comprising: a plotting means having a recording head with a recording pen positioned therein which is adapted to be driven by input signals, said plotting means having a plotting surface for recording lines, symbols or marks applied therein by said recording pen, a keyboard including a plurality of special keys for various functions with respect to drawing a bar graph, a line graph, and a pie chart and general keys for characters, digits and symbols, a controller coupled to said keyboard for executing predetermined programs according to data from said keyboard, and display means coupled to said controller for displaying instructions having an appropriate input of necessary data for plotting in a step-by-step manner in an interactive system, whereby lines, symbols or marks can be directly recorded on said plotting surface of said plotting means by said keyboard.
Claim 3
Dependent Claim
37 words
An interactive graphic system as claimed in claim 1, in which said recording head is provided with a cursor coupled to said recording pen, and the position of said recording pen is specified by positioning said cursor.
Claim 4
Dependent Claim
63 words
An interactive graphic system as claimed in claim 1 in which said keyboard comprises cursor movement keys for specifying the direction of movement of said cursor and an acceleration key for increasing the speed of movement of said cursor, said cursor being movable by operation of said cursor movement keys or by simultaneous operation of said cursor movement keys and said acceleration key.
Claim 5
Dependent Claim
18 words
An interactive graphic system as claimed in claim 1, in which said plotting means comprises a digital plotter.
Claim 6
Dependent Claim
19 words
An interactive graphic system as claimed in claim 1, in which said plotting means comprises an analog X-Y recorder.
Claim 7
Dependent Claim
63 words
An interactive graphic system as claimed in claim 1, in which said keyboard has an execution mode means in which an execution is effected immediately to advance the plotting operation for every instruction thereby set, and a store mode means in which instructions are stored once, and all the plotting operations are carried out at once after the stored instructions have been stored.
