Appeal No. 95-3141
Application No. 08/070,863
Reference to Aron discloses that the plate sections P1
and P2 are employed to facilitate precise leveling of the
elevator car at a particular floor. In one embodiment, this
is achieved by the shaping of the individual plate sections
(the amount of truncation of their apexes) and, in another
embodiment, this is achieved by the width of the shoulders S
of the plates. See column 4, lines 18-25 of Aron.
We find nothing in Aron suggestive of the encoding and/or
position detection described and required by instant claims 2
and 3. More specifically, the claims require first and second
operating devices each comprising a plurality of operating
elements disposed in a row in a direction perpendicular to the
direction of travel of the elevator car “in such positions
that the operation positions can be encoded by using two or
more ON/OFF signals.” The plurality of operating elements of
the first operating device are misaligned with the plurality
of operating elements of the second operating device along the
direction of travel of the elevator car so that when the
elevator car is at any one of the operating positions,
detecting elements are operated by corresponding operating
