Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
In an arrangement for recording characters composed of matrix-like rastered character elements by means of a matrix printer controlled by binary signals supplied column-wise in parallel thereto from a character generator, to normally produce recorded characters having the portions thereof, extending transverse to the direction of the recording line, disposed at a predetermined angle relative thereto, in which such angle may be selectively changed, without change in the disposition of the matrix printer, to provide recorded characters having an appearance different from normal recorded characters, the combination of storage means to which the respective binary signals from the character generator are supplied in parallel, interrogation means connected to said character generator and to the storage means for effecting a time differential between the supply of respective character elements of a column to said storage means, and means for effecting the parallel release of the contents of the storage means to the matrix printer in synchronism with said time differential.
Claim 2
Dependent Claim
159 words
In an arrangement for recording characters composed of matrix-like rastered character elements by means of a matrix printer controlled by binary signals supplied column-wise in parallel thereto from a character generator, to normally produce recorded characters having the portions thereof, extending transverse to the direction of the recording line, disposed at a predetermined angle relative thereto, in which such angle may be selectively changed, without change in the disposition of the matrix printer, to provide recorded characters having an appearance different from normal recorded characters, the combination of storage means to which the respective binary signals from the character generator are supplied in parallel, interrogation means connected to said character generator and to the storage means for effecting a time differential between the supply of respective character elements of a column to said storage means, and means for effecting the parallel release of the contents of the storage means to the matrix printer in synchronism with said time differential.
Claim 3
Dependent Claim
51 words
An arrangement according to claim 1, wherein said storage means comprises pulse-controlled flip-flops for the respective binary signals of a column, and said interrogation means comprises a pulse generator unit, and means operatively connecting said generator unit to the character generator for effecting a serial supply of column binary signals therefrom.
Claim 4
Dependent Claim
44 words
An arrangement according to claim 2, comprising a binary coding device operatively connecting said pulse generator unit to the flip-flops of said storage means, for controlling said flip-flops to serially effect storage of any respective column signals within each period of said time differential.
Claim 5
Dependent Claim
72 words
An arrangement according to claim 3, wherein the output of the said character generator is controlled by a column decoder, and said means connecting the pulse generator unit to the character generator comprises an adding device interposed between the column counter supplying counting values to the column decoder, said adding device being operable to subtract the output values supplied from said pulse generator unit from the output values from the column counter.
Claim 6
Dependent Claim
39 words
An arrangement according to claim 4, wherein said adding device includes means for providing a control signal to the character generator in the event the computed result of the adding device is negative, to thereupon stop the character generator.
