Production of justified coded tape for page printing

Claim 1

A typesetting control system or the like for sequentially responding to a plurality of series of coded input signals each series representing a line of type characters, comprising: input register means, means for supplying a series of coded input signals to said input register means, storage means having an information storage capacity greater than the maximum information in any one of a series of said coded input signals to permit insertion therein of justifying information in addition to line of type information therein, said storage means being arranged to cyclically recirculate information stored therein at a relatively high speed, first gate means between said input register means and said storage means, first control means for said first gate means arranged for gating coded signals from said input register means to said storage means during a plurality of successive recirculatory cycles of said storage means to store in a predetermined order coded signals corresponding to said series of said coded input signals, means for feeding justification code signals to said storage means to be stored therein in a predetermined ordered relationship to said signals corresponding to said input signals, an output channel, second gate means between said storage means and said output channel, and second control means for said second gate means which is operative during a plurality of successive recirculatory cycles of said storage means for feeding to said output channel a first series of output signals representing a line of type characters and a second series of output signals representing justifying operations to be performed with respect to said first series of output signals, said second series of output signals being fed to said output channel in advance of said first series of output signals.
