Multi-stylus recording assembly

Claim 2

A recording assembly for a recorder capable of recording information in the form of a matrix on a suitable recording medium positioned at a recording zone on a backing member comprising: a. a movable member having inner and outer surfaces; b. a body of dielectric material fixed to said outer surface of said driven member; c. a plurality of conductive styli mounted independently on said body and extending away from said outer surface to resiliently engage said recording medium in the form of a linear array of equidistantly spaced contact point; d. a plurality of conductive spring members like in number to said styli mounted independently with said body and extending substantially away from said outer surface; e. means for electrically coupling each of said styli to a respective one of said spring members; f. a commutator assembly including a planar surface substantially parallel to said outer surface and supporting thereon a plurality of conductors adapted to be coupled to recording signals, each conductor associated with a respective one of said spring members, said commutator assembly spaced from said outer surface to resiliently engage said spring members with said conductors; and, g. a support plate supported independent of said movable member and proximate to said inner surface and in slidable contact therewith.

Claim 3

A recording assembly as defined in claim 1 wherein: a. said movable member is an endless belt having two slots therein, one on either side of said body and parallel to the movement of said belt; b. at least two roller means about which said belt is entrained, each of said roller means including two wheels mounted in spaced relationship on a common shaft, the spacing between said wheels on each shaft being greater than the distance separating said slots.

Claim 4

A recording assembly as defined in claim 1 wherein the contact point between said spring members and said conductors lies substantially on a line perpendicular to said outer surface and passing through the midpoint of said body as measured in a direction parallel to the direction of movement of said movable member.

Claim 5

A recording assembly for a recorder capable of recording information in matrix form on a suitable recording medium supported in a recording zone by an elongated backing member comprising: a. an endless drive member having inner and outer surfaces; b. roller means for supporting said drive member in a configuration such that the outer surface of a portion of said drive member is substantially parallel with said backing member; c. a dielectric body mounted on said outer surface; d. a plurality of conductive styli mounted on said body to resiliently engage said recording medium; e. a support plate substantially parallel to said portion of said drive member and proximate said inner surface and inslidable contact therewith; f. a support member having a planar surface substantially parallel to and facing the outer surface of said portion; g. resilient means independently mounted on said body and resiliently engaging said planar surface of said support member for urging said body and that portion of said drive member associated therewith against said support plate.

Claim 6

A recording assembly for a recorder capable of recording information in matrix form on a suitable recording medium supported in a recording zone by an elongated backing member comprising: a. an endless drive member having inner and outer surfaces; b. roller means for supporting said drive member in a configuration such that the outer surface of a portion of said drive member is substantially parallel with said backing member; c. a dielectric body mounted on said outer surface; d. a plurality of conductive styli mounted on said body to resiliently engage said recording medium; e. a support plate substantially parallel to said portion of said drive member and proximate said inner surface and inslidable contact therewith; f. a support member having a planar surface substantially parallel to and facing the outer surface of said portion; g. resilient means independently mounted on said body and resiliently engaging said planar surface of said support member for urging said body and that portion of said drive member associated therewith against said support plate.

Claim 7

A recording assembly as defined in claim 4 wherein said resilient means includes a plurality of spring brushes equidistantly spaced from each other and electrically connected to individual ones of said styli, and said support member includes a plurality of conductive commutator bars on said planar surface for electrical contact with said spring brushes.

Claim 8

A recording assembly for a recorder capable of recording information in the form of a matrix on a suitable recording medium positioned at a recording zone on a backing member comprising: a. a flexible carrier movable through said recording zone, said carrier having first and second surfaces; b. at least one conductive means for translating electrical signals, said at last one conductive means having a resilient brush portion and a stylus portion, adapted to engage the recording medium; c. means attaching said at least one conductive means to one of said surfaces such that said brush portion extends generally away from said attaching means; d. a support positioned adjacent said flexible carrier; e. means including said resilient brush portion of said conductive means for biasing said attaching means toward said support and said flexible carrier into engagement with said support said biasing means and said support cooperating to restrain movement of said attaching means; f. said at least one conductive means being positioned so that said stylus portion engages said recording medium. 7 An assembly according to claim 6 wherein, said support is positioned opposite one of said surfaces and sAid biasing means comprises commutator support means including at least one conductor, said commutator support means being opposite the other of said surfaces.

Claim 9

An assembly according to claim 7 wherein said resilient brush and stylus portions are independently supported by said attaching means.

Claim 10

An assembly according to claim 8 wherein, a. said flexible member is an endless belt having two slots therein, one on either side of said attaching means and parallel to the direction of movement of said belt; and b. said assembly further comprises at least two roller means about which said belt is entrained, each of said roller means including two wheels mounted in spaced relationship on a common shaft, the spacing between said wheels on each shaft being greater than the distance separating said slots.

Claim 11

An assembly according to claim 9 wherein, the contact point between said resilient brushes and said conductors lies substantially on a line perpendicular to said other of said surfaces and passing through the midpoint of said attaching means as measured in a direction parallel to the direction of movement of said flexible member.

Claim 12

An assembly according to claim 6 wherein said resilient brush and stylus portions are independently supported on said attaching means.
