Abstract
A rotatable cylinder having a plurality of drivers mounted therein for axial movement with each driver having a projection thereon extending through openings in the cylinder to engage rotatably mounted rings coaxially positioned around the cylinder and a disk having a depression therein for receiving one of said drivers at a time as the disk and cylinder are rotated. When the disk and cylinder are rotated in one direction a driver positioned in the depression engages an associated ring to rotate the ring. As the disk and cylinder are rotated in an opposite direction the first driver is cammed from the depression and a second driver drops into place. The rings engage different conductors as they rotate to provide the encoding.
Claims10
Fast indexing encoder apparatus comprising:
- a plurality of rotatably mounted members each having contact means engaging encoding means of a generally cylindrically shaped contact board and further including a plurality of individually selectable indices;
- and
- selection means including a rotatable common control coupled to said plurality of members through cam means and a plurality of cammed drivers, said drivers being mounted so that only one is cammed into driving engagement with an associated one of said plurality of members at any time, for selectively rotating any selected one of said plurality of members individually to a preselected one of said indices.
