Abstract
Abstract A dual guide post arrangement for guiding recording tape past the read and write heads on a tape deck. A pair of stationary non-rotating posts is arrayed on at least one side of the tape deck heads; such a post pair guides the tape in its travel between the heads and the supply or take-up reel. Each post which is farthest from the heads includes an upper shoulder limiting the sliding movement of the tape in an upward direction, but which would permit unlimited downward movement. However, the other post of each pair, which is nearest the heads, controls such downward movement and provides ultimate control over alignment of the tape and the heads by including a lower flange. The surface of the lower flange is at a level relative to the effective portions of the heads such that the tape will be correctly guided across the heads. While a pair of posts may be used on each side of the heads, an alternate version provides for a pair of guide posts on only one side of the read and write heads, with a single guide post on the other side of the heads. The provision of a single post between the read head and the capstan permits more uniform speed control of the tape as it is pulled across the head by the capstan, while retaining the advantage of the two guide posts on the other side of the read and write heads.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
251 words
In a tape deck system for operating on recording tape, supply means for storing and providing said tape to said system, take-up means for receiving said tape from said supply means during the operation of said system, drive means for governing the movement of said tape between said supply and said take-up means, means disposed in the travel path of said tape for operating on said tape, and guiding means for aligning said tape with respect to said operating means in said travel path between said supply and said take-up means, said guiding means including at least one pair of guide posts disposed adjacent to each other in said tape travel path between one of said supply means and said take-up means, and said operating means, each of said guide posts having a guide surface for engaging the sides of said tape and one guiding flange in contact with one edge oF said tape, said guiding flange of a first of said guide posts defines a guide surface for one edge of said tape and said guiding flange of the second of said guide posts defines a guide surface for the opposite edge of said tape said guiding flanges of said first and second guide posts having edge portions in substantially vertical alignment thereby providing a pivotal action on said tape by said edges and the distance between said guide surfaces as measured transverse to the direction of said tape travel is no more than the minimum width of said tape.

In a tape deck system for operating on recording tape, supply means for storing and providing said tape to said system, take-up means for receiving said tape from said supply means during the operation of said system, drive means for governing the movement of said tape between said supply and said take-up means, means disposed in the travel path of said tape for operating on said tape, and guiding means for aligning said tape with respect to said operating means in said travel path between said supply and said take-up means, said guiding means including at least one pair of guide posts disposed adjacent to each other in said tape travel path between one of said supply means and said take-up means, and said operating means, each of said guide posts having a guide surface for engaging the sides of said tape and one guiding flange in contact with one edge oF said tape, said guiding flange of a first of said guide posts defines a guide surface for one edge of said tape and said guiding flange of the second of said guide posts defines a guide surface for the opposite edge of said tape said guiding flanges of said first and second guide posts having edge portions in substantially vertical alignment thereby providing a pivotal action on said tape by said edges and the distance between said guide surfaces as measured transverse to the direction of said tape travel is no more than the minimum width of said tape.
Claim 3
Dependent Claim
28 words
A tape deck system as defined in claim 1 wherein said at least one pair of guide posts is disposed between said supply means and said operating means.
Claim 4
Dependent Claim
28 words
A tape deck system as defined in claim 1 wherein said at least one pair of guide posts is disposed between said operating means and said take-up means.
Claim 5
Dependent Claim
19 words
A tape deck system as defined in claim 1 wherein said operating means includes at least one recording head.
Claim 6
Dependent Claim
51 words
A tape deck as defined in claim 1 wherein the selected distance along said tape travel path between the one of said guide posts closest to said operating means, and said operating means, is sufficient to preclude the effect of any skew resulting from said tape riding on said guide surfaces.
Claim 7
Dependent Claim
63 words
A tape deck system as defined in claim 5 wherein said operating means includes a write head and a read head, said selected distance being defined between said one of said guide posts and one of said write and read heads closest to said one guide post and wherein the separation distance between said write and read heads further inhibits said skew effect.
Claim 8
Dependent Claim
55 words
A tape deck system as defined in claim 1 wherein a first pair of said guide posts is disposed along said tape travel path between said supply means and said operating means, and a second pair of said guide posts is disposed along said tape travel path between said operating means and said take-up means.
Claim 9
Dependent Claim
51 words
A tape deck system as defined in claim 7 wherein the configurations of said guide posts of each of said pairs disposed closest to said operating means are substantially identical, and the configurations of said guide posts of each of said pairs disposed remote from said operating means are substantially identical.
Claim 10
Dependent Claim
91 words
A tape deck system as defined in claim 8 wherein each of said guide posts closest to said operating means includes a base portion, said guiding flange thereof being mounted on said base portion to define said guide surface for one edge of said tape, and a shaft portion mounted on said flange, and wherein each of said guide posts remote from said operating means includes a main shaft, said guiding flange thereof being mounted on said main shaft to define said guide surface for the opposite edge of said tape.
Claim 11
Dependent Claim
31 words
A tape deck system as defined in claim 9 wherein said shaft portions and said main shafts of said guide posts establish riding surfaces for only one surface of said tape.
Claim 12
Dependent Claim
70 words
A tape deck system as defined in claim 8 wherein said guiding flanges of each of said first and second pairs of guide posts define respective pairs of guide surfaces for opposite edges of said tape, and wherein said guide surfaces of each of said pairs of guide posts are separated in a direction transverse to tape movement by a distance no greater than the minimum width of said tape.
Claim 13
Dependent Claim
58 words
A tape deck system as defined in claim 11 wherein the selected distance along said tape travel path between each of said guide posts of said first and said second pairs closest to said operating means, and said operating means, is sufficient to preclude the effect of any skew resulting from said tape riding on said guide surfaces.
Claim 14
Dependent Claim
57 words
A tape deck system as defined in claim 12 wherein said operating means includes a write head and a read head, said selected distance being defined between said each of said closest guide posts and said write and read heads respectively, and wherein the separation distance between said write and read heads further inhibiTs said skew effect.
Claim 15
Dependent Claim
39 words
A tape deck system as defined in claim 1 including in addition a single guide post disposed along said tape travel path on the opposite side of said operating means from said at least one pair of guide posts.
