PURPOSE:To prevent shift of adjustment not in use, by projecting knobs only at adjustment at a recess at the lower front of a cabinet. CONSTITUTION:When a TV receiver is not adjusted, a knob 8 is pushed from the front of a cabinet 1 to move a rotary shaft 6 backward and the state is held at a push-push mechanism 7. Since the knob 8 is not projected in the recess 2, the adjustment can not be shifted uncautionlessly. In adjusting the receiver, the knob 8 is again depressed to release the lock by the mechanism 7. Then, the rotary shaft 6 is moved forward and the knob 8 is projected in the recess 2. The user turns the knob 8 and can arbitrarily adjust the adjusting member 5. Since the knob is projected only at adjustment, the shift of adjustment not in use can be prevented. |
