Abstract
Abstract A recording apparatus for recording a pattern by a plurality of dots comprises: discriminating means for discriminating whether or not the dot which exists in the dot series to be recorded next is located obliquely to the dot recorded previously; and control means which, in the case where it is determined by the discriminating means that the obliquely located dot exists, makes a drive of this dot different from an ordinary drive, thereby enabling this obliquely located dot to be recorded for a slightly longer recording time. With this apparatus, particularly, an oblique line can be smoothly and sharply recorded so that a recording quality of a character, figure or the like is greatly improved.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
104 words
An apparatus for recording one complete pattern by recording a combination of a plurality of partial patterns in at least one of an ordinary manner and an altered manner, comprising: discriminating means for determining whether a partial pattern next to be recorded is located at a predetermined position relative to a partial pattern presently to be recorded; and control means for recording said partial pattern presently to be recorded in the altered manner when it is determined by said discriminating means that the partial pattern next to be recorded is located at the predetermined position relative to said partial pattern presently to be recorded.
Claim 2
Independent Claim
104 words
An apparatus for recording one complete pattern by recording a combination of a plurality of partial patterns in at least one of an ordinary manner and an altered manner, comprising: discriminating means for determining whether a partial pattern next to be recorded is located at a predetermined position relative to a partial pattern presently to be recorded; and control means for recording said partial pattern presently to be recorded in the altered manner when it is determined by said discriminating means that the partial pattern next to be recorded is located at the predetermined position relative to said partial pattern presently to be recorded.
Claim 3
Dependent Claim
37 words
An apparatus according to claim 1, further comprising storing means having a first storage section for storing the partial pattern next to be recorded and a second storage section for storing the partial pattern to be recorded.
Claim 4
Dependent Claim
33 words
An apparatus according to claim 2, wherein said discriminating means has processing means for operating the partial pattern next to be recorded and the partial pattern to be recorded in said storing means.
Claim 5
Independent Claim
107 words
An apparatus for forming a pattern by providing a dot matrix including a series of dots recorded in at least one of an ordinary manner and a different manner, the apparatus comprising: discriminating means for determining whether a dot in a dot series next to be recorded is located obliquely relative to a dot presently to be recorded; and control means for recording said dot in a dot series presently to be recorded in the different manner when it is determined by said discriminating means that the dot in the dot series next to be recorded is located obliquely relative to said dot presently to be recorded.
Claim 6
Independent Claim
107 words
An apparatus for forming a pattern by providing a dot matrix including a series of dots recorded in at least one of an ordinary manner and a different manner, the apparatus comprising: discriminating means for determining whether a dot in a dot series next to be recorded is located obliquely relative to a dot presently to be recorded; and control means for recording said dot in a dot series presently to be recorded in the different manner when it is determined by said discriminating means that the dot in the dot series next to be recorded is located obliquely relative to said dot presently to be recorded.
Claim 7
Dependent Claim
35 words
An apparatus according to claim 4, wherein said control means has means for lengthening the recording time of the dot located obliquely to the dot to be recorded to provide the different manner of recording.
Claim 8
Dependent Claim
21 words
An apparatus according to claim 4, further comprising a thermal head connected to said control means for recording the dot series.
Claim 9
Dependent Claim
13 words
An apparatus according to claim 4, wherein said discriminating means has operating means.
Claim 10
Dependent Claim
37 words
An apparatus according to claim 4, further comprising storing means having a first storage section for storing the dot series next to be recorded and a second storage section for storing the dot series to be recorded.
Claim 11
Independent Claim
141 words
An apparatus for forming a pattern by providing a dot matrix including a series of dots recorded in at least one of an ordinary manner and a different manner, the apparatus comprising: storing means having a first storage section for storing a dot series next to be recorded and a second storage section for storing a dot series presently to be recorded; detecting means for comparing the dot series stored in said second storage section with the dot series next to be recorded stored in said first storage section to detect any dots in the dot series next to be recorded located obliquely relative to dots in said dot series presently to be recorded; and control means for recording said dots in the dot series presently to be recorded in the different manner when dots are detected by said detecting means.
Claim 12
Independent Claim
141 words
An apparatus for forming a pattern by providing a dot matrix including a series of dots recorded in at least one of an ordinary manner and a different manner, the apparatus comprising: storing means having a first storage section for storing a dot series next to be recorded and a second storage section for storing a dot series presently to be recorded; detecting means for comparing the dot series stored in said second storage section with the dot series next to be recorded stored in said first storage section to detect any dots in the dot series next to be recorded located obliquely relative to dots in said dot series presently to be recorded; and control means for recording said dots in the dot series presently to be recorded in the different manner when dots are detected by said detecting means.
Claim 13
Dependent Claim
18 words
An apparatus according to claim 9, further comprising a thermal head which is connected to said control means.
Claim 14
Dependent Claim
19 words
An apparatus according to claim 9, wherein said detecting means has a processing section connected to said storing means.
