Abstract
Abstract There is provided an output apparatus having the function to temporarily store pattern data to be output. The apparatus comprises: a first converter to convert vector data which expresses a pattern to be output into compression data in which the corresponding dot pattern was compressed; a second converter to convert the compression data converted by the first converter into the dot pattern; and an output device to output the dot pattern converted by the second converter. The apparatus also comprises: a data memory which can store vector data indicative of an output pattern, in a plurality of kinds of data formats different from the vector format; a converter for converting into the dot pattern on the basis of either one of the data formats stored in the data memory; and an output device to output the dot pattern converted by the converter.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
66 words
An output apparatus comprising: first converting means for converting vector data which expresses a pattern to be output into compression data which is obtained by compressing the corresponding dot pattern; second converting means for converting said compression data which was converted by said first converting means into the dot pattern; and output means for outputting the dot pattern which was converted by said second converting means.
Claim 2
Dependent Claim
66 words
An output apparatus comprising: first converting means for converting vector data which expresses a pattern to be output into compression data which is obtained by compressing the corresponding dot pattern; second converting means for converting said compression data which was converted by said first converting means into the dot pattern; and output means for outputting the dot pattern which was converted by said second converting means.
Claim 3
Dependent Claim
71 words
An output apparatus comprising: data memory means which can store vector data which expresses a patternto be output in a plurality of kinds of data formats different from a vector; converting means for converting into a dot pattern on the basis of either one of the data formats which are stored in said data memory means; and output means for outputting the dot pattern which was converted by the converting means.
Claim 4
Dependent Claim
71 words
An output apparatus comprising: data memory means which can store vector data which expresses a patternto be output in a plurality of kinds of data formats different from a vector; converting means for converting into a dot pattern on the basis of either one of the data formats which are stored in said data memory means; and output means for outputting the dot pattern which was converted by the converting means.
Claim 5
Dependent Claim
70 words
An output apparatus comprising: memory means for storing run length data or dot data corresponding to a pattern; first determining means for discriminating whether the dot data corresponding to the pattern to be output exists in said memory means or not; and second determining means for discriminating whether said corresponding run length data exists or not if the absence of the dot data is determined by said first determining means.
Claim 6
Dependent Claim
70 words
An output apparatus comprising: memory means for storing run length data or dot data corresponding to a pattern; first determining means for discriminating whether the dot data corresponding to the pattern to be output exists in said memory means or not; and second determining means for discriminating whether said corresponding run length data exists or not if the absence of the dot data is determined by said first determining means.
Claim 7
Dependent Claim
90 words
An output apparatus comprising: memory means for storing run length data or dot data corresponding to a pattern; discriminating means for discriminating whether said run length data and said dot data corresponding to the pattern to be output have been stored in said memory means or not; and converting means for converting the vector data corresponding to the pattern to be output into the dot data if it is determined by said discriminating means that the run length data and said dot data do not exist in the memory means.
Claim 8
Dependent Claim
90 words
An output apparatus comprising: memory means for storing run length data or dot data corresponding to a pattern; discriminating means for discriminating whether said run length data and said dot data corresponding to the pattern to be output have been stored in said memory means or not; and converting means for converting the vector data corresponding to the pattern to be output into the dot data if it is determined by said discriminating means that the run length data and said dot data do not exist in the memory means.
Claim 9
Dependent Claim
70 words
An output apparatus comprising: data memory means which can store vector data which expresses a pattern to be output in a plurality of kinds of data formats different from a vector; designating means for designating either one of the data formats which are stored in said data memory means; and converting means for converting into the dot pattern on the basis of the data format designated by said designating means.
Claim 10
Dependent Claim
70 words
An output apparatus comprising: data memory means which can store vector data which expresses a pattern to be output in a plurality of kinds of data formats different from a vector; designating means for designating either one of the data formats which are stored in said data memory means; and converting means for converting into the dot pattern on the basis of the data format designated by said designating means.
Claim 11
Dependent Claim
85 words
An output apparatus comprising: memory means which can express a pattern by a plurality of kinds of data formats different from a vector format and can store; discriminating means for discriminating a size of a pattern; converting means for converting vector data which expresses said pattern into a data format of the kind based on the since which was determined by said discriminating means; and memory control means for storing said pattern into the memory means in said data format converted by said converting means.
Claim 12
Dependent Claim
85 words
An output apparatus comprising: memory means which can express a pattern by a plurality of kinds of data formats different from a vector format and can store; discriminating means for discriminating a size of a pattern; converting means for converting vector data which expresses said pattern into a data format of the kind based on the since which was determined by said discriminating means; and memory control means for storing said pattern into the memory means in said data format converted by said converting means.
Claim 13
Dependent Claim
93 words
An output apparatus for converting vector data into dot data and outputting comprising: a first conversion path for converting said vector data into intermediate data different from the dot data and for converting said intermediate data into the dot data; a second conversion path for directly converting said vector data into said dot data; and determining means for determining whether a pattern to be output is output by using said first or second conversion path or not on the basis of an output speed and a data memory capacity corresponding to said pattern.
Claim 14
Dependent Claim
93 words
An output apparatus for converting vector data into dot data and outputting comprising: a first conversion path for converting said vector data into intermediate data different from the dot data and for converting said intermediate data into the dot data; a second conversion path for directly converting said vector data into said dot data; and determining means for determining whether a pattern to be output is output by using said first or second conversion path or not on the basis of an output speed and a data memory capacity corresponding to said pattern.
