Abstract
Abstract Electronic equipment has a memory which stores input data to be displayed. The data read out from the memory is formed as a corresponding character pattern signal and is output from a character pattern generator. The character pattern signal generated by the character pattern generator is displayed in n characters at a display section in response to a first mode signal which is supplied by a mode switching section. The mode switching section supplies different display mode signals determined by the contents of the data to be displayed. The character pattern signal from the character pattern generator is displayed in m characters (n<m) at the display section in response to a second mode signal supplied by the mode switching section.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
212 words
Electronic equipment comprising: memory means for storing input data to be displayed; character pattern signal generating means including first and second sets of character patterns and coupled to said memory means, for generating a selected one of first and second character pattern signals each corresponding to the input data to be displayed in response to a corresponding mode signal; display means including a display section in which a plurality of dot display elements are aligned in a matrix form, for displaying the data which is stored in said memory means in response to the selected character pattern signal from said character pattern signal generating means; mode signal generating means for generating different first and second mode signals in response to a detected display mode of the data to be displayed by said display means; and display control means including selecting means for selecting one of said first and said second character patterns in response to said detected display mode, for displaying the data which is stored in said memory means in n characters in response to the first mode signal which is generated by said mode signal generating means, and for displaying the data which is stored in said memory means in m characters (n<m) in response to the second mode signal.
Claim 2
Dependent Claim
212 words
Electronic equipment comprising: memory means for storing input data to be displayed; character pattern signal generating means including first and second sets of character patterns and coupled to said memory means, for generating a selected one of first and second character pattern signals each corresponding to the input data to be displayed in response to a corresponding mode signal; display means including a display section in which a plurality of dot display elements are aligned in a matrix form, for displaying the data which is stored in said memory means in response to the selected character pattern signal from said character pattern signal generating means; mode signal generating means for generating different first and second mode signals in response to a detected display mode of the data to be displayed by said display means; and display control means including selecting means for selecting one of said first and said second character patterns in response to said detected display mode, for displaying the data which is stored in said memory means in n characters in response to the first mode signal which is generated by said mode signal generating means, and for displaying the data which is stored in said memory means in m characters (n<m) in response to the second mode signal.
Claim 3
Dependent Claim
45 words
Electronic equipment according to claim 1, wherein said mode signal generating means includes a changeover switch which has first and second contacts for providing the first and the second mode signals, wherein corresponding first and second display modes can be switched by an external operation.
Claim 4
Dependent Claim
115 words
Electronic equipment according to claim 1, further comprising operation means coupled to said mode signal generating means, said mode signal generating means having overflow detecting means for detecting whether or not data characters entered from outside, or operated results within said operation means based on data characters entered from outside, exceed the capacity of said memory means, said mode signal generating means being set in a first display mode to generate said first mode signal when said overflow detecting means does not detect an overflow condition, and said mode signal generating means being set in a second display mode to generate said second mode signal when the said overflow detecting means detects the overflow condition.
Claim 5
Dependent Claim
180 words
Electronic equipment according to claim 1, further comprising operation means for storing data characters entered from outside, or operation results calculated within said operation means based on data characters entered from outside, in significant figure parts and exponent parts, when the data characters entered from outside or the operation results calculated within said operation means based on the data characters entered from outside exceed the number of characters to be displayed at said display means; and mode signal switching means coupled to said operation means and including detecting means for detecting whether or not the display data has the exponent part, said mode signal switching means being operative to cause display of n characters in a first display mode by generating said first mode signal when said detecting means detects that the display data does not have the exponent part, and to cause display of m characters (n<m) comprising the significant figure parts and exponent parts in a second display mode by generating said second mode signal when said detecting means detects that the display data has the exponent part.
Claim 6
Dependent Claim
21 words
Electronic equipment according to claim 1, wherein said display means is a liquid crystal display device comprising dot matrix display elements.
