Abstract
Abstract In a financial calculator, a graphic representation function is provided, and financial values desired for an operator are calculated based upon various input financial data. Also, both the entered data and calculated values are displayed as a graphic representation. In the graphic representation, a display interval of a pattern is determined based upon the number of the display data, and a magnitude of the pattern is determined based on the magnitude of the data value.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A graphic representation apparatus having a matrix type display screen, comprising: storing means for storing data to be displayed; representing means for converting said data stored in said storing means into graphic patterns, and for graphically representing said data to be displayed by said graphic patterns; detecting means for detecting an uninterrupted sequence of the same patterns to be displayed on said display screen; omitting means for omitting a selected number of patterns from the uninterrupted sequence detected by said detecting means and for indicating on said display screen that such omission has been made.
Claim 2
Dependent Claim
95 words
A graphic representation apparatus having a matrix type display screen, comprising: storing means for storing data to be displayed; representing means for converting said data stored in said storing means into graphic patterns, and for graphically representing said data to be displayed by said graphic patterns; detecting means for detecting an uninterrupted sequence of the same patterns to be displayed on said display screen; omitting means for omitting a selected number of patterns from the uninterrupted sequence detected by said detecting means and for indicating on said display screen that such omission has been made.
Claim 3
Dependent Claim
45 words
A graphic representation apparatus as claimed in claim 1, wherein: said detecting means includes means for detecting a sequence of more than three of the same patterns; and said omitting means includes means for indicating an omitted portion of said sequence by a dotted line.
Claim 4
Dependent Claim
51 words
A graphic representation apparatus as claimed in claim 2, wherein said data to be displayed correspond to PV (present value), PMT (payment) and FV (future value) data used in a compound interest calculation, and a portion of a sequence of patterns representing said PMT data is omitted by said omitting means.
Claim 5
Dependent Claim
45 words
A graphic representation apparatus as claimed in claim 2, wherein said data to be displayed correspond to PRC, CPN, and RDV data used in an investment appraisal, and a portion of a sequence of patterns representing said CPN data is omitted by said omitting means.
Claim 6
Dependent Claim
66 words
A graphic representation apparatus as claimed in claim 1, wherein: said detecting means includes means for detecting a sequence of more than two of the same patterns; and said omitting means includes: means for omitting all except one of said same patterns for which said detecting means detects said sequence; and means for adding a symbol to said one remaining pattern to indicate the omitted patterns.
Claim 7
Dependent Claim
38 words
A graphic representation apparatus as claimed in claim 5, wherein said added symbol is displayed on the display screen as a dot pattern, and the number of dots in said dot pattern represents the number of omitted patterns.
Claim 8
Dependent Claim
87 words
A graphic representation apparatus having a matrix type display screen, comprising; means for storing a number of data items to be displayed; and means for graphically representing the stored data items; said graphically representing means including: pattern storing means for storing a plurality of graphic patterns; pattern selecting means for selecting one of the stored graphic patterns automatically based upon the number of said data items to be displayed; and means for determining a length of the selected pattern based upon a value of the stored data.
Claim 9
Dependent Claim
87 words
A graphic representation apparatus having a matrix type display screen, comprising; means for storing a number of data items to be displayed; and means for graphically representing the stored data items; said graphically representing means including: pattern storing means for storing a plurality of graphic patterns; pattern selecting means for selecting one of the stored graphic patterns automatically based upon the number of said data items to be displayed; and means for determining a length of the selected pattern based upon a value of the stored data.
Claim 10
Dependent Claim
70 words
A graphic representation apparatus as claimed in claim 7, wherein: said pattern storing means includes means for storing an arrow pattern and a bar pattern; and said pattern selecting means includes: means for selecting the arrow pattern when the number of said data items is lower than a predetermined number; and means for selecting the bar pattern when the number of said data items is higher than a predetermined number.
Claim 11
Dependent Claim
28 words
A graphic representation apparatus as claimed in claim 8, wherein said data items to be displayed correspond to CF (cash flow) data used in an investment appraisal calculation.
