Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an operation panel device for electronic equipment, such as a video tape recorder (VTR).

(B) Prior Art In a VTR, it is necessary for the user to specify various operations, and the panel section is equipped with operating devices for this purpose, such as push buttons for specifying operations, push buttons for timer setting, tracking volume, etc. ing.
Recently, front-loading thin VTRs have been commercialized for design and space reasons. With such a thin VTR, various operating devices can be installed in the limited space on the front panel.
The problem is how to arrange them without impairing operability.

For example, the knobs 1 and 1 of the tracking volume, which are provided for compatibility with other devices, were conventionally arranged as shown in Figure 1, but this method is difficult to adopt in order to achieve a thinner design. . Therefore, as shown in FIG. 2, it is conceivable to provide a tracking volume knob 1 inside a lid 3 that can be opened and closed and is attached to a panel 2. This lid 3 has a timer setting operation button 4 placed inside, which is thought to be used less frequently than others, and the lid was provided mainly for design reasons and to avoid errors in the timer setting device. This is for the purpose of preventing the user from being manipulated.

However, with this configuration, when operating the tracking volume knob 1, the lid 3 must be opened, and providing the tracking volume knob 1, which is likely to be used many times, on the inside impairs operability. It is also necessary to increase the strength of the lid 3.

A configuration in which a tracking volume knob 1 is provided as shown in FIG. 3 is also conceivable, but the knob 1 itself is large in size and has poor operability.

When the tracking volume is placed inside the lid, the shape of the lid may also affect the operability of the tracking volume. FIG. 4 shows a conventionally used lid locking structure, in which a locking means 3a for locking the panel 2 is arranged at a position away from the center of rotation 5 of the lid 3. With this structure, when the lid is open, the locking means 3a is exposed, which is not aesthetically pleasing.Furthermore, since the locking means 3a protrudes, it may get stuck in the hand when operating the tracking volume, impairing operability. arise.

(c) Purpose of the invention This invention was created in view of the above points,
It is an object of the present invention to provide an operation panel device that has good operability of arranged operation devices and is effective in reducing the thickness.

(d) Structure of the device The device includes a panel having a recess in which an operating member is placed, and a lid for the recess that takes two positions: an open position and a closed position. Further, the recess and/or the lid body is provided with an allowance portion through which the operating member is exposed, and even when the lid body is in a closed state, a part of the operating member is exposed. It is.

(e) Examples An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 5A and 5B are perspective views showing two states of an embodiment of the present invention, that is, an open state and a closed state. In the figure, 6 is the main body chassis of the VTR, 7
8 is a front panel, 8 is a recess provided in the panel 7 in which a timer setting button 9 and tracking volume knobs 10 and 11 are arranged, and 12 is a lid for the recess. The lid body 12 is rotatably fixed to the panel 7 so as to be in an open state (a) and a closed state (b).

There are two tracking volumes, one for normal compatibility and one for intermittent slow playback. The knobs 10 and 11, which are operating members, are fitted into recesses 8a, which are open at the bottom of the panel 7 and serve as knob-permitting parts. In the closed state B of the lid body 12, as shown in the figure, the external operation part 10 of the knob
Parts a and 11a are exposed at the bottom of the panel. Although not shown in the figure, symbols, characters, etc. indicating the purpose of the knob are printed on the lid body 12 corresponding to the knob position.

6A and 6B are cross-sectional views of the vicinity of the knob, and correspond to FIGS. 5A and 5B, respectively. The tracking volume 13 is fixed to the printed circuit board 14,
It is fixed to the rear of panel 7. A through hole 8b for a volume 13 is provided in the recess 8 of the panel 7, and a shaft 13a protrudes from the back surface. A knob 10 is fixed to this shaft. The knob 10 is provided with an external operating section 10a and an internal operating section 10b. When the lid body 12 is in the closed state A, the external operation section 10a protruding from the lower part of the panel 7 can be operated. Furthermore, when the lid 12 is in the open state as shown in (b), tracking can be adjusted using the internal operation section 10b.

A notch 12a is provided in the lower part of the lid 12 at a location corresponding to the recess 8a of the panel 7.
Due to this notch 12a, even if the external operation part 10a protrudes, the opening/closing operation of the lid body 12 is not hindered.

Next, the locking means for the lid 12 will be explained.
FIG. 7 is a sectional view showing this. In the figure,
7b is a shaft provided on the panel 7; 12b is a holding portion provided at both ends of the lid body 12 to elastically hold the shaft 7b; 12c is a locking protrusion provided on the holding portion 12b; 7c is This is a hook that engages with this protrusion 12c. In the panel 7, the shaft 7b and the hook 7c are provided in a notch 7d that allows insertion of the holding portion 12b.

That is, the protrusion 12c and the elastic hook 7
The lid 12 is held in the closed state shown in FIG. 7 by engagement with the lid 12. When opening the lid 12 from the closed state,
Place your finger on the end of the lid 12 at the notch 7a on the side of the panel shown in FIG. At this time, protrusion 1
The elastic hook 7c climbs over 2c, and the two are disengaged. Conversely, when closing the lid body 12,
The hook 7c climbs over the protrusion 12c from the opposite direction. Once over, the elasticity of the hook 7c applies a force in the direction of closing the lid 12, and the lid 12 is brought into a closed state.

In this manner, in this embodiment, unlike the conventional example shown in FIG. 4, the locking means 3a does not spoil the aesthetic appearance when in the open state, nor does it interfere with the operation of the knobs 10, 11.

8 to 11 are sectional views showing other embodiments near the operating member. Components that are the same as those in the first embodiment are given the same figure numbers.

In the embodiment shown in FIG. 8, the cross-sectional shape of the lid 12' is different. This is not explicitly stated, but the front of the panel itself is sloped to match that. A notch 12a' through which a part of the knob is exposed is provided only in the lid body 12'. In the embodiment shown in FIG. 9, the knob 10 itself is arranged at the rear of the panel 7', the internal operation part 10b protrudes from the through hole 7'a of the panel 7', and the external operation part 10b protrudes from the through hole 7'a of the panel 7'.
0a is configured to be exposed from a notch 7'b at the bottom of the panel.

In the embodiment shown in FIG. 10, in order to make the knob operation more stable when the lid 12 is closed, a recess 10c is provided in the knob head, and a protrusion 12b that fits into the recess is provided on the back side of the lid 12. ing. In FIG. 11, a biaxial variable resistor 15 is used. These two axes are not linked and move independently. A knob portion 16a corresponding to the external operation portion in the above embodiment is connected to the outer shaft 15a,
Only the outer shaft 15a can be operated from the outside. A knob portion 16b corresponding to an internal operation section is connected to the inner shaft 15b, and can be operated only when the lid body 12' is open. outer shaft 1
5a corresponds to the tracking volume for compatibility in normal playback, and the inner shaft 1
5b is a throat tracking volume. This is because tracking volumes for the purpose of compatibility are considered to be used more frequently. A configuration in which the inner shaft is not a variable resistor but a rotary switch for switching the timer mode, etc. is also conceivable.

In the above, the panel, lid, knob, etc. are molded products made of synthetic resin.

(f) Effects of the invention As described above, according to the invention, it is possible to realize a practical operation panel device that has excellent operability and is suitable for thinning and downsizing.
