Abstract: An operating device having a rotary knob capable of rotation operations exhibits compatibility between speed and precision in operation and does not require use of a plurality of rotary knobs. In the operating device (1) including the rotary knob (4) and the rotation detecting means (8) for detecting the rotated angle of the rotary knob, the rotary knob includes a small-diameter component (4F) for operating the rotary knob quickly, and a large-diameter component (4S) for operating the rotary knob slowly or for fine adjustment, and the determining means (9) is provided for determining the rotated position of the rotary knob when the rotary knob is operated.

Abstract: An adjustment device with a dual-guiding structure has two worm wheels respectively meshed with two coaxial worm gears. The two worm gears are pivotally and longitudinally fixed by a driving shaft in line. An adjacent end of each worm gear has a locking recess to receive a locking head mounted on the driving shaft. Thereby, the locking head is selectively engaged with the locking recess of one of the worm gears to drive the corresponding worm gear when the locking head on the driving shaft is reciprocated. Then, one worm wheel engaged with the corresponding worm gear is rotated to rewind or release the wires on the work wheel.
