Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
An apparatus for recording visual and tactual information comprising: a keyboard having a plurality of keys; a cylindrical platen; means for journalling said platen so as to permit rotation about the axis of the cylinder; a plurality of cylindrical disks each journalled for rotation about an axis parallel to the axis of said cylindrical platen; linkage means responsively connecting each of said keys with one of said disks so as to cause said disks to rotate when the associated key is struck; means responsive to each key for rotating said platen each time that a key is depressed; and ratchet clutch means for disengaging said disks and said platen when said key is released whereby said disk and platen will remain in the position effected when said key is fully depressed; a plurality of embossing heads on the circumference of each of said disks; means for feeding a pressure sensitive recording medium between said platen and said disks; means for positioning the journalled axis of each of said disks so as to cause said embossing heads to exert pressure on the recording medium when said disk and platen are rotated by the depression of a key.
Claim 2
Independent Claim
196 words
An apparatus for recording visual and tactual information comprising: a keyboard having a plurality of keys; a cylindrical platen; means for journalling said platen so as to permit rotation about the axis of the cylinder; a plurality of cylindrical disks each journalled for rotation about an axis parallel to the axis of said cylindrical platen; linkage means responsively connecting each of said keys with one of said disks so as to cause said disks to rotate when the associated key is struck; means responsive to each key for rotating said platen each time that a key is depressed; and ratchet clutch means for disengaging said disks and said platen when said key is released whereby said disk and platen will remain in the position effected when said key is fully depressed; a plurality of embossing heads on the circumference of each of said disks; means for feeding a pressure sensitive recording medium between said platen and said disks; means for positioning the journalled axis of each of said disks so as to cause said embossing heads to exert pressure on the recording medium when said disk and platen are rotated by the depression of a key.
Claim 3
Dependent Claim
56 words
The apparatus recited in claim 1 wherein said means for rotating said platen comprises: an elongated bar positioned so as to rest in contact with each of said linkage means for actuating said disks; means connecting said bar with said cylindrical platen whereby the depression of any key will cause said bar to move said platen.
Claim 4
Dependent Claim
20 words
The apparatus recited in claim 1 wherein said embossing heads comprise: a raised alphabetic character, and; a raised Braille equivalent.
Claim 5
Dependent Claim
14 words
The apparatus recited in claim 3 wherein said platen includes an elastically deformable surface.
Claim 6
Dependent Claim
16 words
The apparatus recited in claim 4 wherein each disk includes a plurality of identical embossing heads.
