Abstract
Abstract A settable margin control switch is actuated when a movable carriage printer approaches the right hand margin. In the keyboard operating mode, an audible alarm is sounded and a predetermined number of character positions later, the printing of keyboard originated data is blocked. In the automatic printing mode, no alarm is sounded, however, printing is terminated and a special character is printed beyond the right hand margin to indicate that the input data has overflowed the printed record.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
A margin control system in combination will a recorder having a recording assembly that moves across a record medium and records characters in respective column positions in response to discrete character signals available from a source, comprising: switch means settable for actuation by said recording assembly at any selected column position thereof; and indicator means operative in response to said recording assembly transversing a predetermined number of said column positions following actuation of said switch means to control recording of a special symbol in a succeeding column position.
Claim 2
Dependent Claim
88 words
A margin control system in combination will a recorder having a recording assembly that moves across a record medium and records characters in respective column positions in response to discrete character signals available from a source, comprising: switch means settable for actuation by said recording assembly at any selected column position thereof; and indicator means operative in response to said recording assembly transversing a predetermined number of said column positions following actuation of said switch means to control recording of a special symbol in a succeeding column position.
Claim 3
Dependent Claim
56 words
A margin control system in accordance with claim 1, wherein said source comprises a keyboard means for producing other discrete character signals, and alarm means operative only in response to said discrete signals being produced by said keyboard means to provide an audible signal upon movement of said recording assembly following actuation of said switch means.
Claim 4
Dependent Claim
54 words
A margin control system in accordance with claim 2, comprising means operative only in response to said discrete signals being produced by said keyboard means to block recording of discrete character signals produced by said keyboard means when said recording assembly has traversed a predetermined number of positions following actuation of said switch means.
Claim 5
Dependent Claim
82 words
A margin control system in accordance with claim 1, wherein said indicator means comprises a signal generator operative to produce an output signal upon positioning of said recording assembly at the end of each column position following said selected position, a counter operative to count said output signgals, means for enabling said counter upon activation of said switch means, and means operative upon registration of a count corresponding to said predetermined number for generating a discrete character signal representing said special symbol.
Claim 6
Dependent Claim
32 words
A margin control system in accordance with claim 4, including means operative upon registration of one count beyond said predetermined number, to prevent further recording in response to subsequent discrete character signals.
Claim 7
Dependent Claim
50 words
A margin control system in accordance with claim 5, further including keyboard means for producing discrete character signals, and alarm means operative only in response to discrete signals produced by said keyboard means, to activate an audible signal upon movement of said recording assembly following actuation of said switch means.
Claim 8
Dependent Claim
54 words
A margin control system in accordance with claim 6, comprising means operative only in response to said discrete signals being produced by said keyboard means to block recording of further character signals associated with said keyboard means when said recording assembly has traversed a predetermined number of positions following actuation of said switch means.
Claim 9
Dependent Claim
60 words
A margin control system in accordance with claim 1, further comprising keyboard means for manually producing other discrete signals; and means responsive to discrete character signals produced by said source and not produced by said keyboard means for indicating the source of said discrete signals and enabling said indicator means to operate only in response to said last named indication.
Claim 10
Dependent Claim
87 words
A margin control system for use with recorders having a recording assembly that moves across a record medium and records characters in respective column positions in response to discrete character signals available from a source, comprising: switch means settable for actuation by said recording assembly at any selected column position thereof; and indicator means operative in response to said recording assembly transversing a predetermined number of said column positions following actuation of said switch means to control recording of a special symbol in a succeeding column position.
Claim 11
Dependent Claim
87 words
A margin control system for use with recorders having a recording assembly that moves across a record medium and records characters in respective column positions in response to discrete character signals available from a source, comprising: switch means settable for actuation by said recording assembly at any selected column position thereof; and indicator means operative in response to said recording assembly transversing a predetermined number of said column positions following actuation of said switch means to control recording of a special symbol in a succeeding column position.
