Abstract
Abstract A machine is disclosed for simultaneously making type-written and magnetic records, for editing magnetic records, and for automatically making typewritten record copies of edited or unedited magnetic records. The editing typewriter comprises typewriter elements including a platen and printing type spaced from the platen. Means are provided for moving the typewriter elements into and out of positions of mutual contact and for laterally stepping one of the typewriter elements with respect to the other. The editing typewriter also comprises magnetic recorder elements including a magnetic head and a magnetic record support. Structural means are provided ''''pantographically'''' linking one of the typewriter elements with one of the magnetic recorder elements whereby one of the magnetic recorder elements may be stepped with respect to the other of the magnetic recorder elements when one of the typewriter elements is laterally stepped with respect to the other of the typewriter elements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
199 words
An editing typewriter comprising typewriter elements consisting of a platen for holding and feeding a sheet and printing type spaced from the platen; means for stePping one of the typewriter elements with respect to the other of the typewriter elements to effect character spacing within a line of type on the sheet; and means, including manual means, for stepping the platen to feed the sheet held thereon in a direction orthogonal to the character spacing to effect line-to-line spacing; in combination with magnetic recorder elements in said typewriter operable in serial-by-bit fashion and comprising a unitary read and write magnetic head together with a magnetic card and a support for said magnetic card, said magnetic card being separate from said sheet; and mechanical means positively responsive to said stepping means for character spacing and line-to-line spacing, including manually-controlled line-to-line spacing, and cooperable respectively with one of said magnetic head and card support of said magnetic recorder elements whereby said one of said magnetic head and card support may be linearly correspondingly stepped with respect to the other of said magnetic head and card support when said platen and said printing type are stepped in said character and line-to-line spacing.
Claim 2
Dependent Claim
199 words
An editing typewriter comprising typewriter elements consisting of a platen for holding and feeding a sheet and printing type spaced from the platen; means for stePping one of the typewriter elements with respect to the other of the typewriter elements to effect character spacing within a line of type on the sheet; and means, including manual means, for stepping the platen to feed the sheet held thereon in a direction orthogonal to the character spacing to effect line-to-line spacing; in combination with magnetic recorder elements in said typewriter operable in serial-by-bit fashion and comprising a unitary read and write magnetic head together with a magnetic card and a support for said magnetic card, said magnetic card being separate from said sheet; and mechanical means positively responsive to said stepping means for character spacing and line-to-line spacing, including manually-controlled line-to-line spacing, and cooperable respectively with one of said magnetic head and card support of said magnetic recorder elements whereby said one of said magnetic head and card support may be linearly correspondingly stepped with respect to the other of said magnetic head and card support when said platen and said printing type are stepped in said character and line-to-line spacing.
Claim 3
Dependent Claim
73 words
An editing typewriter in accordance with claim 1 comprising a typewriter carriage and a stationary printing station, and wherein said platen is cylindrical and rotatably mounted on said carriage for incremental angular stepping, said printing type are mounted for movement and into and out of positions of contact with said platen at said stationary printing station, and wherein said carriage is mounted for stepping movement in a lateral path through said printing station.
Claim 4
Dependent Claim
38 words
An editing typewriter in accordance with claim 2 wherein said magnetic head is mounted for movement with said carriage, and said magnetic card support positions said magnetic card in a plane substantially parallel to said lateral carriage path.
Claim 5
Dependent Claim
51 words
An editing typewriter in accordance with claim 3, wherein said mechanical means comprise means for stepping said magnetic head with respect to said magnetic card support over said plane in a direction substantially orthogonal to said lateral carriage path to provide line space stepping response to angular stepping of said platen.
Claim 6
Dependent Claim
40 words
An editing typewriter in accordance with claim 4 wherein said means for stepping said magnetic head in said direction substantially orthogoanl to said lateral carriage path includes drive transmission means mechanically linking said magnetic head with said rotatably mounted platen.
Claim 7
Dependent Claim
26 words
An editing typewriter in accordance with claim 5 wherein said drive transmission means includes a train of gears and means for detenting one of said gears.
Claim 8
Dependent Claim
32 words
An editing typewriter in accordance with claim 1 wherein said printing type is a font member steppable to effect said character spacing, and said magnetic head is linked to said font member.
Claim 9
Dependent Claim
26 words
An editing typewriter in accordance with claim 7 wherein said printing type comprises a ball printing element having a convex surface from which character font project.
Claim 10
Dependent Claim
46 words
An editing typewriter in accordance with claim 7 wherein said platen is cylindrical and is mechanically linked by rack and pinion drive transmission means with said magnetic card support to provide line space stepping of the magnetic card in response to angular stepping of said platen.
Claim 11
Dependent Claim
47 words
An editing typewriter in accordance with claim 1 and said platen is cylindrical, wherein said magnetic card support includes a roller mechanically coupled to said platen by gear train means to provide line space stepping of said magnetic card in response to angular stepping of said platen.
Claim 12
Dependent Claim
42 words
An editing typewriter in accordance with claim 1 wherein said magnetic head is mechanically linked by rack and pinion drive transmission means with said platen to provide line space stepping of said magnetic head in response to angular stepping of said platen.
