PURPOSE: To provide a control unit of a medical device which can easily be set at various positions without danger of bringing about unintended changes in settings. CONSTITUTION: The penetrating sleeve 6 of a setting/switching knob 5 is rotatably placed on a front panel 1, and a knob core 10 is movably placed within the penetrating sleeve 6 while having spring elasticity and is thereby controllable from the front surface of the front panel 1; when no force is applied to the knob core, the setting/switching knob 5 is fixed by a claw 12 in at least one rotating direction, and when a force is applied to the knob core 10 against a spring device, the setting/switching knob 5 is rotatable in both rotating directions. |
