Abstract

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.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention consists of 1. To provide a configuration of an adjustment device used in a television receiver, etc., which will not be tampered with by children when not in use, and which can also have a good appearance.

In television receivers, etc., a recess is provided at the lower front of the cabinet, and the variable resistor knob for color adjustment and contrast adjustment is protruded from the ceiling of the recess so that adjustment can be made with the fingers. is used.

However, in this case, conventional controls have the disadvantage that because the knobs are always exposed, children or other children may change the settings unnecessarily, causing the adjustment state to deteriorate, or the knobs are always visible from the front, resulting in an unsightly appearance. there were.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an apparatus that eliminates such conventional drawbacks.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In the figure, reference numeral 1 denotes a synthetic resin case or vignette for a television receiver or the like, and a recess 2 is provided in the lower front surface thereof. In the recess 2, a window 3 is formed from the ceiling surface to the bottom surface. On the other hand, reference numeral 4 denotes a printed circuit board mounted below inside the cabinet 1, on which a rotary adjustment member 6 such as a variable resistor is mounted. Reference numeral 6 denotes a rotating shaft for adjustment thereof, which is provided here so as to be rotatable and movable back and forth through the adjusting member 5, and its rear end is connected to a so-called push-button mechanism 7.

This pushbutton mechanism 7 is also attached to the printed circuit board 4. The rotation shaft 6 is connected to the rotation adjustment element in the adjustment member 6 by making the cross-sectional shape of the central portion non-circular. Then, a knob 8 is attached to the tip of the rotating shaft 6.

With this configuration, when not adjusting the television receiver, etc., as shown in FIG. The mechanism 7 holds it. Then, since the knob 8 does not protrude into the recess 2, there is no possibility that a child or the like will turn it negligently, and the adjustment will not be inadvertently shifted. Moreover, in this state, the knob 6 is not visible from one side of the front of the cabinet 1, so the appearance is also good.

Next, if you wish to make an adjustment, press the knob 8 in the state shown in FIG. 1 again with your finger to release the lock by the pushbutton mechanism 7. Then, the rotating shaft 6 is moved forward by the forward biasing force of the spring, and the knob 8 projects from the ceiling surface into the recess 2 as shown in FIG. Therefore, the user can turn this knob 8 with his or her fingers 9 to adjust the adjustment member 6 as desired. After adjustment, it is sufficient to return to the state shown in FIG. 1 again.

In the above embodiment, the rotating shaft passes through the adjusting member and is connected to the push-button mechanism, but when using a normal variable resistor, another rotating shaft that can be moved back and forth is separately provided. This may be coupled to the shaft of the variable resistor using a gear or the like.

As described above, according to the present invention, since the knob can be made to protrude from the recessed part at the lower front of the cabinet only when making adjustments, it is possible to prevent the knob from being unnecessarily changed by children or the like when not in use. Furthermore, it is possible to obtain an adjustment device with a good appearance because the knob is not visible when not in use, and which has great practical effects.
