Abstract
Abstract In a method and apparatus for reconstructing Chinese characters such as in a printer system, each of the characters is divided into a pair of components at least one of which occurs in one or more other characters. The components which have a height equal to the height of a standard character cell are stored together with information as to the locations of the components across the width of the standard character cell for each character. The components may be stored in a compressed form, in which event the information as to their location forms a part of the compressed data. When a given character is to be reconstructed, the first component thereof is transferred to a buffer where it is temporarily stored at the proper location across the width of a standard character cell. Thereafter, the second component is transferred to a logic circuit together with the temporarily stored first component, and the two are logically OR'ed to form the complete character. The complete character may then be advanced to imaging apparatus of a printer or other utilizing means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A machine implementable method for reconstructing Chinese-like whole characters in a designated alphabet comprising the steps of: storing component parts of like size in a given dimension of the Chinese-like characters in the designated alphabet as a first set of data, together with representations of the locations of the component parts within a standard space occupied by each character as a second set of data, each component having a predetermined fixed size and shape within the standard space; and responding to a command to reconstruct a given character from the designated alphabet in the standard space by selecting and pairwise combining the component parts of the given character from the first set of data and locating the selected component parts within the standard space in selectively displaced or superimposed relation in accordance with representations of the location of the component parts from the second set of data.
Claim 2
Dependent Claim
147 words
A machine implementable method for reconstructing Chinese-like whole characters in a designated alphabet comprising the steps of: storing component parts of like size in a given dimension of the Chinese-like characters in the designated alphabet as a first set of data, together with representations of the locations of the component parts within a standard space occupied by each character as a second set of data, each component having a predetermined fixed size and shape within the standard space; and responding to a command to reconstruct a given character from the designated alphabet in the standard space by selecting and pairwise combining the component parts of the given character from the first set of data and locating the selected component parts within the standard space in selectively displaced or superimposed relation in accordance with representations of the location of the component parts from the second set of data.
Claim 3
Dependent Claim
145 words
A machine implementable method for reconstruction of whole ideographic characters in a designated alphabet comprising the steps of: storing a graphical representation of each of a plurality of components of the characters, together with information as to the identities and relative locations of the components comprising each of the characters, each of the components having a predetermined fixed size and shape within a standard space occupied by each character; and thereafter responding to a command to reconstruct a given one of the characters by: identifying the components comprising the character and information as to the relative location of the components within the standard space; and forming the pairwise graphical representations of the identified components in the standard space in selectively displaced or superimposed relation in accordance with the information as to the relative location of the components to form a graphical representation of the character.
Claim 4
Dependent Claim
145 words
A machine implementable method for reconstruction of whole ideographic characters in a designated alphabet comprising the steps of: storing a graphical representation of each of a plurality of components of the characters, together with information as to the identities and relative locations of the components comprising each of the characters, each of the components having a predetermined fixed size and shape within a standard space occupied by each character; and thereafter responding to a command to reconstruct a given one of the characters by: identifying the components comprising the character and information as to the relative location of the components within the standard space; and forming the pairwise graphical representations of the identified components in the standard space in selectively displaced or superimposed relation in accordance with the information as to the relative location of the components to form a graphical representation of the character.
Claim 5
Dependent Claim
177 words
A machine implementable method for the reconstruction of whole ideographic characters comprising the steps of: encoding and storing each whole ideographic character C in a designated alphabet as the code equivalent of selected members of a first stored set R of dot matrix graphical components and selected members of a second stored set D of displacement, rotation, and width information, set R consisting of unique subcharacters of predetermined fixed size and shape within a standard space for each character, further, set R subcharacters being selected from those whole characters partitionable into two subcharacters at least one of which is common to a plurality of the whole characters; and forming selected ones of the whole ideographic characters C upon command by logically combining members of the sets R and D such that: C=R.sub.1 D.sub.1 +R.sub.2 D.sub.2 where "+" is a general Boolean logical operator, R 1 and R 2 are selected from the set R and D 1 and D 2 are selected from the set D, selected ones of the components abutting and some superimposing when combined.
Claim 6

A machine implementable method for the reconstruction of whole ideographic characters comprising the steps of: encoding and storing each whole ideographic character C in a designated alphabet as the code equivalent of selected members of a first stored set R of dot matrix graphical components and selected members of a second stored set D of displacement, rotation, and width information, set R consisting of unique subcharacters of predetermined fixed size and shape within a standard space for each character, further, set R subcharacters being selected from those whole characters partitionable into two subcharacters at least one of which is common to a plurality of the whole characters; and forming selected ones of the whole ideographic characters C upon command by logically combining members of the sets R and D such that: C=R.sub.1 D.sub.1 +R.sub.2 D.sub.2 where "+" is a general Boolean logical operator, R 1 and R 2 are selected from the set R and D 1 and D 2 are selected from the set D, selected ones of the components abutting and some superimposing when combined.
Claim 7
Dependent Claim
81 words
A machine implementable method for the reconstruction of whole ideographic characters from selected ones of a prestored set of graphical strokes and orientation data, the method steps comprise: responsive to a command defining an ordered sequence of elements of stroke and orientation data: forming selected whole characters by the combining of graphical strokes pairwise and selectively spacing or superimposing strokes within a fixed frame; and applying said formed whole characters to a display device such as a printer or the like.
