Abstract

Abstract A character processing device is disclosed that is capable of representing function codes, which comprise at least a portion of information processing codes input to the device, as a single character code pattern comprising a first character code pattern representative of a classifying character code, which indicates that a function code has been input to the device, and second character code pattern representative of a function character code, which indicates the function represented by the function code.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 238 words
A character processing device comprising: input means for inputting to said device a plurality of established numeric codes, a first predetermined range of numerical values of said numeric codes representing function codes and a second predetermined range of numerical values of said numeric codes representing character codes; identifying means for receiving numeric codes input to said device by said input means and identifying each numeric code as a function code or a character code by comparing the numerical value of each received numeric code with the first and second predetermined ranges; converting means operable when said identifying means identifies a numeric code representing a function code to convert the function code into a classifying character code and a function character code, the classifying character code constituting a signal that a function code has been identified, and the function character code constituting a signal of the function represented by the function code; memory means including a first memory unit for storing said classifying character code and a second memory unit for storing said function character code; selecting means for selecting a first character code pattern representative of the classifying character code stored in said first memory unit and a second character code pattern representative of the function character code stored in said second memory unit; and synthesizing means for producing a single code pattern from the first and the second character code patterns respectively selected by said selecting means.
Claim 2
Dependent Claim 238 words
A character processing device comprising: input means for inputting to said device a plurality of established numeric codes, a first predetermined range of numerical values of said numeric codes representing function codes and a second predetermined range of numerical values of said numeric codes representing character codes; identifying means for receiving numeric codes input to said device by said input means and identifying each numeric code as a function code or a character code by comparing the numerical value of each received numeric code with the first and second predetermined ranges; converting means operable when said identifying means identifies a numeric code representing a function code to convert the function code into a classifying character code and a function character code, the classifying character code constituting a signal that a function code has been identified, and the function character code constituting a signal of the function represented by the function code; memory means including a first memory unit for storing said classifying character code and a second memory unit for storing said function character code; selecting means for selecting a first character code pattern representative of the classifying character code stored in said first memory unit and a second character code pattern representative of the function character code stored in said second memory unit; and synthesizing means for producing a single code pattern from the first and the second character code patterns respectively selected by said selecting means.
Claim 3
Dependent Claim 48 words
A character processing device according to claim 1, wherein said selecting means comprises signal generating means for signaling said memory means to alternately and cyclically put out the classifying character code stored in said first memory unit and the function character code stored in said second memory unit.
Claim 4
Dependent Claim 75 words
A character processing device according to claim 2, further comprising means, operable when said identifying means identifies an information processing code as a character code, for transmitting the character code to both said first memory unit and said second memory unit for storage therein, and wherein said signal generating means comprises a character generating device for generating duplicate character code patterns representative of the character code stored in said first and said second memory units.
Claim 5
Dependent Claim 30 words
A character processing device according to claim 1, wherein said synthesizing means comprises means for visually displaying the first and second code patterns as synthesized as the single code pattern.
Claim 6
Dependent Claim 181 words
A character processing device comprising: identifying means for identifying input data as function data or character data; converting means operable when said identifying means identifies said input data as function data to convert said input data into first character data indicative of function data and second character data indicative of classification of function data, said converting means adapted to designate predetermined character data used as said first character data, to operationally process said predetermined character data on the basis of a numerical value code representative of said input data, and to designate character data representative of the numerical value code of the processed data as said second character data; memory means including a first memory unit for storing said first character data converted by said converting means and a second memory unit for storing said second character data; selecting means for alternately selecting said first character data and said second character data stored in said memory means; and display means for providing a superposed display of both said first character data and said second character data supplied from said selecting means.
Claim 7
Dependent Claim 181 words
A character processing device comprising: identifying means for identifying input data as function data or character data; converting means operable when said identifying means identifies said input data as function data to convert said input data into first character data indicative of function data and second character data indicative of classification of function data, said converting means adapted to designate predetermined character data used as said first character data, to operationally process said predetermined character data on the basis of a numerical value code representative of said input data, and to designate character data representative of the numerical value code of the processed data as said second character data; memory means including a first memory unit for storing said first character data converted by said converting means and a second memory unit for storing said second character data; selecting means for alternately selecting said first character data and said second character data stored in said memory means; and display means for providing a superposed display of both said first character data and said second character data supplied from said selecting means.
