Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
A scanner, comprising a. a housing having a flat surface against which copy carrying a graphic display can be pressed, the surface having an elongated reading slot, b. a pressure member for holding the copy against the surface, and c. two arms mounted on the housing on opposite sides of the said surface and serving to support the pressure member, wherein each arm is U-shaped, the free end of one leg of each arm is pivotally attached to the housing for hinged movement about an axis perpendicular to the surface, and the free end of the other leg of each arm is connected to the pressure member.
Claim 2
Dependent Claim
107 words
A scanner, comprising a. a housing having a flat surface against which copy carrying a graphic display can be pressed, the surface having an elongated reading slot, b. a pressure member for holding the copy against the surface, and c. two arms mounted on the housing on opposite sides of the said surface and serving to support the pressure member, wherein each arm is U-shaped, the free end of one leg of each arm is pivotally attached to the housing for hinged movement about an axis perpendicular to the surface, and the free end of the other leg of each arm is connected to the pressure member.
Claim 3
Dependent Claim
69 words
A scanner as recited in claim 1, wherein the copy is slowly moved over the surface past the slot by two rollers located parallel to and on opposite sides of the slot, the surfaces of the rolls extending only slightly above the surface for contact with the copy, the peripheral speed of the roll on the downstream side of the slot being greater than that of the other roll.
Claim 4
Dependent Claim
37 words
A scanner as recited in claim 1, wherein the connection of the said other leg to the pressure member permits pivotal action about the same axis as the connection of the said one leg to the housing.
Claim 5
Dependent Claim
26 words
A scanner as recited in claim 1, wherein an extension of the said flat surface would extend between the legs and they are parallel to it.
Claim 6
Dependent Claim
54 words
A scanner as recited in claim 1, wherein the U-shaped arms can be swung from a first position perpendicular to the slot against the sides of the housing to a second position parallel to the slot and extending outwardly from the housing so that copy considerably larger than the flat surface can be accommodated.
Claim 7
Dependent Claim
59 words
A scanner as recited in claim 1, wherein the connection between the pressure member and the said other leg is such that the pressure member is free to swing about a first axis that is parallel to the surface and perpendicular to the slot and also about a second axis parallel to the surface and parallel to the slot.
Claim 8
Dependent Claim
62 words
A scanner as recited in claim 6, wherein the said connection includes a secondary arm that is attached at one end to the first-mentioned arm for pivotal movement about an axis parallel to and substantially spaced from the slot, and wherein the other end of the secondary arm is attached to the adjacent end of the pressure member for limited universal movement.
Claim 9
Dependent Claim
31 words
A scanner as recited in claim 7, wherein the said one end of the secondary arm is connected to the first-mentioned arm for movement about an axis perpendicular to the surface.
Claim 10
Dependent Claim
78 words
A scanner, comprising a. a housing having a flat surface against which copy carrying a graphic display can be pressed, the surface having an elongated reading slot, b. a pressure member for holding the copy against the surface, c. two arms mounted on the housing on opposite sides of the said surface and serving to support the pressure member, and d. staggered elongated lamps extending parallel to each other and parallel to the slot to illuminate the copy.
Claim 11
Dependent Claim
78 words
A scanner, comprising a. a housing having a flat surface against which copy carrying a graphic display can be pressed, the surface having an elongated reading slot, b. a pressure member for holding the copy against the surface, c. two arms mounted on the housing on opposite sides of the said surface and serving to support the pressure member, and d. staggered elongated lamps extending parallel to each other and parallel to the slot to illuminate the copy.
