Abstract
A code disc is spline-connected to an operation unit supported such that it can rotate and move vertically and sandwiched between a center cylinder and a return spring. Rotation of the operation unit is detected by photointerruptors through the code disc and vertical movement of the operation unit is detected by a photointerruptor through a cylinder.
