Abstract
A control mechanism for generation of a pair of analog signals wherein the mechanism includes a support and an analog element mounted on the support for rotation and translation relative thereto. The support includes an elongated guide member, and the analog element is rotatably mounted on the guide member and is movable relative to and longitudinally of the guide member. A first encoder is coupled to the analog element for sensing rotation thereof relative to the support. A second encoder is coupled with the analog element for sensing translation of the analog element relative to the support. Several embodiments of the control mechanism are disclosed.

20. A control mechanism comprising:
-
a support including an elongated guide member; a hand manipulatable device mounted on the support guide member said device being movable in both rotation and linear movement in a linear direction relative to the support; means coupled with the device for adjusting the value of a first signal as a function of the rotation of the device relative to the support; and means coupled with the device for adjusting the value of a second signal as a function of the movement of the device in said linear direction relative to the support. - View Dependent Claims (21, 22)
