Description

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

(b) Prior Art In electronic devices such as video tape recorders (VTRs), operation button devices are used for various operations. For example, in a VTR, there are a power button, an operation button for commanding operations, a channel selection button, a timer setting button, and the like.

Here, since the timer setting button is not used all the time, it is often constructed with a lid as shown in FIG. The operation button 3 is provided in a recess 2 at the bottom of the panel 1, and the recess is normally covered with a lid 4. The lid 4 is attached to the panel 1 so as to be openable and closable, and when the lid is opened, the operation buttons can be operated with fingers.

However, this configuration has the drawback that the operation button is provided in a recess at the bottom of the panel, making it difficult to operate. This drawback becomes even more problematic when the VTR 5 becomes thinner (Figure 2), and the space occupied by the operation button device 6 is limited, resulting in situations where it becomes difficult to insert fingers or the lid obstructs operation. .

(c) Purpose of the invention The present invention was created in view of the above points, and the purpose of the invention is to provide an operation button device with a lid that is normally closed, and which has good operability. shall be.

(d) Structure of the invention In the present invention, a lid body that can be opened and closed is provided in the recessed part of the panel in which the operation switch is provided, and an operation button is supported on the back of the lid body, and the operation switch is operated by this operation button. This is an operation button device characterized by the following.

(e) Embodiment An embodiment of the present invention applied to timer operation will be described below with reference to the drawings. Fig. 3 is a perspective view showing a part of the embodiment with a cutaway; Fig. 4 A, B, and C are cross-sectional views of the lid in the closed state, open state, and operation state, respectively; Fig. 5 is a partial front view of the panel. It is.

In the figure, 10 is a panel of a VTR, 11 is a panel recess provided at the bottom of the panel, 12 is a lid of the recess, and 13 is an operation button. The lid body 12 includes a plate-shaped main body 12a, a U-shaped bearing portion 12b formed on the main body, and an engagement piece 12c that engages with the panel recess 11. A spring plate 14 is fixed to the main body 12a by fusion. The operation button 13 has an operation piece 13b and a pressing piece 13c extending in opposite directions around a cylindrical bearing part 13a.

To attach the operation buttons 13 to the lid 12, arrange the required number of operation buttons in a row on the main body 12a to which the spring plate 14 is fixed (on the back side of the lid), and insert the through holes 12d of the bearing portion 12b. metal shaft 15
Insert. At the same time, the shaft 15 is also inserted through the bearing portion 13a of the operation button 13. With the shaft 15 inserted into the bearing portion 12b, clip rings 16,
16, the operation button 13 becomes the cover body 1.
2 is supported and fixed.

The spring plate 14 includes a mounting portion 14a and a tongue piece 14b extending from the mounting portion in a comb-like shape.
The tongue piece 14b is provided for each operation button, and comes into contact with the pressing piece 13c to push the pressing piece 13c into the main body 12.
energize it in the direction away from a. In this state, the operating piece 13c and the bearing portion 12b come into contact with each other, and positioning is performed. The shaft 15 serves as a pivot point for the operation button 13 and also serves as a pivot point for the lid body 12.

Side walls 11a, 11a forming panel recess 11
is provided with holding parts 11b, 11b for the shaft 15, and both ends of the shaft 15 are held in the holding parts 11b, 11b.
By fitting the cover body 12 into the panel recess 1
It can be attached to 1 so that it can be opened and closed.

On the front side of the panel recess 11, there is a regulating part 11c for positioning the lid 12 in the closed state, and an engaging piece 1 of the lid.
The first wall portion 11e includes a hole 11d that engages with the first wall portion 11e.
and a second wall portion 11f having an arcuate cross section that allows rotation of the lid body 12 about the shaft 15.
An opening 1 is provided between the first wall portion 11e and the second wall portion 11f.
7, and an operating switch 19 fixed to a printed circuit board 18 faces there. The printed circuit board 18 is provided on the main body chassis (not shown) side of the VTR, and the operation switches are arranged as shown in the figure when the panel 10 is fixed to the main body chassis.

The second wall portion 11f is provided with a stepped portion 11g having different radii, which abuts a portion of the main body 12a when the lid 12 is open, thereby positioning the lid.

Next, the operation will be explained according to FIG. In the closed state A of the lid 12, the lid 12 is held by the engagement between the engagement piece 12c and the hole 11d. Lid body 12
When rotated to the open state B, the stepped portion 11g and the main body 1
2a, the operation switch 19 and the protrusion 13d of the operation piece 13b are held close to each other. The position of the lid body 12 at this time is the stepped portion 11g.
It can be determined by the position of When the pressing piece 13c biased by the spring plate 14 is pressed in this open state B, the operating button 13 is rotated and the corresponding operating switch 19 is operated.

In the embodiments described above, the lid is held in the open state by its own weight, but a configuration in which a separate holding means is provided is also conceivable. It is a matter of course that a symbol indicating the nature of the operation is attached to the pressing piece 13c of the operation button. Moreover, it can of course be used not only for timer operation but also for other operations such as operation commands, channel selection, etc.

(F) Effects of the invention As described above, the present invention supports the operation button on the back side of the panel lid, and is configured so that the operation switch is operated by the operation button when the lid is open, resulting in improved operability. An operation button device can be realized and is effective.
