2. Description of the Related Art FIG. 5 is a partial cross-sectional view showing a conventional operating device provided in an on-vehicle audio equipment, and FIG. 6 is a rear view of a push button provided in FIG. A plurality of push buttons 2 are movably supported on an operation panel 1a that is the front surface of the nose portion 1 of the vehicle audio equipment. An operation protrusion 2 a is integrally formed on the back surface of the push button 2. A switch (operation electronic component) S mounted on a circuit board P is provided inside the operation panel 1a.
Is mounted, and the switch S is pressed by the operation protrusion 2a of the push button 2.

Between the operation panel 1a and the circuit board P,
A light guide member 3 formed of a light guide resin material such as acrylic resin is provided. A light source such as a lamp is attached to the circuit board P, and light from this light source is guided by the light guide member 3
Incident on the inside. This light propagates through the light guide member 3 and illuminates the entire push button 2, the illuminated portion formed on the push button 2, or the illuminated portion provided on the operation panel 1a. On the back surface of the push button 2, a pair of elastic arms 2b, 2b are provided.
Are formed so as to extend in a V shape, and the elastic arms 2b, 2b are formed.
The tip portions 2 c, 2 c of the light guide member 3 are supported by hitting the support surface 3 a on the surface of the light guide member 3. In the operation device shown in FIG. 5, when the push button 2 is pressed, the switch S is pressed by the tip of the operation protrusion 2a. At this time, the elastic arms 2b, 2b
Are deformed in the direction of opening each other, and their tip portions 2c, 2c slide on the support surface 3a. When the pressing force of the push button 2 is removed,
The push button 2 returns in the protruding direction by the elastic return force of the elastic arms 2b, 2b.

FIG. 7 is a cross-sectional view showing another conventional operating device. In FIG. 7, elastic arms 2b, 2b extending in the V-shaped direction (the direction of extension in the C-shaped direction is the direction perpendicular to the paper surface) are provided at the center of the back surface of the push button 2, and the leading ends 2c, 2c thereof are guided. It is slidably supported on the support surface 3 a on the surface of the optical member 3. This point is the same as that shown in FIG. In FIG. 5, the operation protrusion 2a for pressing the switch S is formed in the center of the push button 2, whereas in the conventional example shown in FIG. 7, the operation protrusion 2a is formed in the center of the push button 2, that is, the elastic arm 2b. , 2b are formed at a position deviated to one side portion from the central portion where they are provided.

[0005]

In the conventional example shown in FIGS. 5 and 7, the surface of the light guide member 3 made of synthetic resin such as acrylic resin slides on the tip portions 2c, 2c of the elastic arms 2b, 2b. It is the support surface 3a. The surface of acrylic resin is smooth. When the push button 2 is pressed, the elastic arms 2b, 2b are deformed so that the tip portions 2c, 2c thereof are separated from each other, and the tip portions 2c, 2c slide on the smooth supporting surface 3a in the x direction. It will be. At this time, there is a problem that a sliding sound is generated between the support surface 3a and the tip portions 2c, 2c of the elastic arms 2b, 2b. Especially when the humidity is high and the surface of the support surface 3a is wet, the tip portions 2 of the elastic arms 2b, 2b are
A sliding noise called "kyu" is generated between c and 2c and the support surface 3a, and this is propagated to the light guide member 3 and amplified,
It will sound as noise outside the device.

Further, in the conventional example shown in FIG. 7, the operation projection 2
Since a is formed at a position deviated from the center of the push button 2 to one side, when the central portion of the push button 2 is pressed with the force F, the reaction force f of the switch S is the center of the push button 2. It acts on a position biased from. Due to the couple of the pressing force F and the reaction force f,
The operation feeling when the push button 2 is pressed becomes very bad. Further, when the pressing force F applied by the finger acts on the right side portion of the push button 2 shown in FIG.
May not be pushed securely, which may result in an operation error.

The present invention is to solve the above-mentioned conventional problems, and to prevent a sliding noise from occurring between the tip portion of the elastic arm of the push button and the supporting surface when the push button is operated. It is an object.

Further, according to the present invention, even when the portion for pressing the operation electronic component is provided at a position deviated from the center of the push button, a good operation feeling can be obtained, and a space is provided. Even if only one elastic arm can be formed on the push button due to the circumstances, it is an object of the present invention to obtain the same reaction force as that of the push button having a pair of elastic arms.

[0009]

According to the present invention, there is provided a first push button provided on an operation panel so as to be able to perform a pressing operation, and the first push button.

It is characterized in that it slides on the formed fine irregularities .

Alternatively, the small protrusions may be provided on the tip of the elastic arm, and the supporting surface may be finely textured. This fine unevenness processing is to reduce the adhesion with the tip of the elastic arm, and for example, the surface of the supporting surface made of acrylic resin or the like is blasted into a frosted glass by mechanical processing or chemical processing. It is realized by.

Further, when the projection for pressing the operation electronic component is formed at a position deviated from the center of the push button to one side portion, the elastic arm is opposite to the projection from the center of the push button. It preferably extends from a position biased to the side.

Further , the elastic arm is attached to the second push button.
Is provided, and the elastic arm is formed thicker than the first elastic arm.

[0013]

In the above means, when the push button is pushed, the operation electronic parts such as the switch arranged inside the operation panel are pushed by the push button to operate. At this time, the elastic arm provided on the push button elastically deforms, and the tip of the elastic arm slides on the support surface. When the pressing force of the push button is removed, the push button returns in the protruding direction due to the elastic return force of the elastic arm. When the push button is pressed, the tip of the elastic arm slides on the support surface, but if a small projection is provided on the tip and the small projection slides on the support surface, the tip of the elastic arm is The contact area of the sliding portion between the bearing surface and the supporting surface becomes small, and a sliding noise of "cuddling" does not occur when the tip of the elastic arm and the supporting surface slide. Alternatively, if minute irregularities are formed by blasting on the surface of the support surface on which the elastic arm slides, close contact sliding between the elastic arm and the support surface does not occur, and sliding noise can be similarly eliminated.

In a preferred example, a small protrusion is provided on the tip of the elastic arm, and the surface of the support surface is made into a minute uneven surface by blasting, and the small projection is slid on the minute uneven surface subjected to the blasting. This makes it possible to very effectively eliminate the sliding noise caused by the sliding of the small protrusions.

Further, when the protrusion for pressing the operation electronic component is provided at a position deviated to one side with respect to the center of the push button, the elastic arm is deviated from the center to the opposite side. If it is provided, the pressing resistance force applied to the projection from the operation electronic component and the elastic return force by the elastic arm act equally on the push button, and when the pressing force is applied to any position of the push button. Even in this case, the push buttons are pressed in a well-balanced manner, the operation feeling is good, and the operation electronic parts such as the switch can be operated reliably.

Furthermore, if it is not possible to only provide one resilient arm from space constraints on pushbutton, thicker than each of the elastic arms provided two in thickness and another pushbutton of the elastic arm when things, the elastic restoring force of both the push button is substantially equal, thereby the operation feeling when pressing both push buttons on the same.

2c, 22c, 23c, 23c, 24c, 24c are integrally formed. When the push buttons 21 to 24 are pushed, the stoppers 21c to 24c hit the support surface 33a,
As a result, the pushing amount of each push button is regulated.

The push buttons 21 to 24 are made of synthetic resin, and elastic arms are integrally formed on the back surface thereof. On the back surface of the first push button 21, a pair of elastic arms 51a and 51b extend obliquely from the push button 21 side toward the inside of the operation panel 11 in a direction of gradually widening, and the elastic arms 51a and 51b are in the shape of a V. It is arranged in a shape. Second

As shown in FIG. 3, on the rear surface of each push button 21-24, each elastic arm projects from the upper side portion (b) of the push button. That is, the operation protrusions 21b to 24
b is formed at a position deviated in the direction of the side portion (a) below the center of the push button, and the elastic arm is an upper side portion which is the side opposite to the side portion (a) with respect to the center of the push button. It is formed at a position deviated in the (b) direction. Moreover, as shown in FIG. 4, when the push button is viewed from the rear side, each elastic arm extends along the upper side portion (b) of the push button, that is, parallel to the side surface (b). There is. The tips 51c and 51d of the elastic arms 51a and 51b provided on the first push button 21 are formed by bending the elastic arms 51a and 51b at a substantially right angle in the projection of FIG. Similarly, the elastic arm 52 of the second push button 22 has a tip portion 52a formed at a right angle. Similarly, the elastic arms 53a and 53b of the third push button 23 have tip portions 53c and 53, respectively.
The elastic arm 54 of the fourth push button 24 has a tip 54a.

The tip portions 51c, 51 of each elastic arm are
Small protrusions A are integrally formed on the portions of d, 52a, 53c, 53d, and 54a facing the support surface 33a. The small protrusion A is formed to minimize the contact area with the support surface 33a. Therefore, it is preferable that these small protrusions A have a spherical shape, a conical shape, or the like and can make point contact with the supporting surface 33a. However, the small protrusion A may have a minute cylindrical shape, and the minute circular portion at the tip thereof may contact the supporting surface 33a. In addition, the tip portions 51c, 51d, 52a, 53c, 53d, 54 on the support surface 33a of the support plate 33.
Particularly, a portion of a where the small protrusion A hits is a roughened surface E on which fine irregularities are formed. The roughened surface E has a frosted glass shape or a matte surface shape, and is, for example, polished with an abrasive material having fine particles, machined with fine abrasive particles with an abrasive tool, or chemically treated with a chemical or the like. The surface is blasted by processing or the like.

The tip 51c of the elastic arm 51a of the first push button 21 and the tip 52 of the elastic arm 52 of the second push button 22 are also provided.
The respective ends of a are connected to each other by a hinge connecting part B. The tip 51d of the elastic arm 51b of the first push button 21 and the tip 5 of the elastic arm 53a of the third push button 23 are also provided.
Each end of 3c is connected by a hinge connecting portion B. Similarly, the tip portion 53d of the elastic arm 53b and the elastic arm 5 are
The tips of the tip portions 54a of No. 4 are connected to each other by the hinge connecting portion B. The support pin C is attached to each hinge connecting portion B.
Are integrally formed. The support plate 33 has three support holes 35 formed therein.
Inserted in. By connecting the tip portions of the elastic arms by the hinge connecting portion, the four push buttons 21 to 2 are connected.
4 can be handled as one component connected to each other.

Here, the adjacent first push button 21 and second
The push buttons 22 have the same size, and the operation protrusions 21b and 22b are also formed at the same positions on the push buttons 21 and 22, respectively. However, the first push button 2
1 has a pair of elastic arms 51a and 51b formed in a V shape, whereas the second push button 22 has a pair of elastic arms 51a and 51b.
Only the elastic arms 52 of the book are provided. The same applies to the fourth push button 24. Second like this
The reason that only one elastic arm 52 is provided on the push button 22 is that the elastic arm also has a function of connecting the push buttons adjacent to each other, but the second push button 22 has the right side in FIG. Since there is no push button to be further connected to, the provision of the elastic arm in the right portion (portion (c)) in the drawing merely complicates the shape of the component. Further, by not providing the elastic arm in the portion (c), it is possible to eliminate a portion projecting from the push button 22 to the area (c) and prevent waste of space when the push button is arranged.

However, the elastic arm is provided with a push button on the operation panel 11
Since the first push button and the second push button having the same size are provided, a pair of elastic arms is provided on one side, and only one elastic arm is provided on the other side. Then, the resistance force felt by the finger when the first push button 21 and the second push button 22 are respectively pressed is different, and a sense of discomfort is felt during the operation. Therefore, in the illustrated embodiment, when the adjacent push buttons of the same size are provided, the second push button 2
One elastic arm 52 of No. 2 is replaced with the elastic arm 5 of the first push button 21.
It is thicker than 1a and 51b. Preferably, the sectional area of the elastic arm 52 is twice as thick as the sectional area of the elastic arm 51a or 51b. As a result, the first push button 21
When is pressed and when the second push button 22 is pressed,
Operation resistance is the same.

Next, the operation of the operating device having the above configuration will be described. For example, when the first push button 21 is pressed, the operation protrusion 2
The switch S is pushed by 1b, and the switch S is put into an operating state. The tips 51c and 51d of the elastic arms 51a and 51b, which are integral with the push button 21, are in contact with the blasted roughened surface E of the support surface 33a via the small protrusions A. When the push button 21 is pressed, each elastic arm 51a, 51b
Is the direction indicated by (i) in FIG. 2, that is, the operation panel 11
The inner sides of the elastically deform in the direction of opening each other. However, the tip end portions of the tip portion 51c of the elastic arm 51a and the tip portion 52a of the elastic arm 52 of the push button 22 adjacent to each other are coupled by the hinge coupling portion B, and the push button 23 adjacent to the tip portion 51d of the elastic arm 51b. The distal ends of the elastic arms 53a and the tip portion 53c are connected to each other by the hinge connecting portions B, and the support pins C provided in the respective hinge connecting portions B are inserted into the support holes 35 of the support plate 33 with the minimum clearance or Fitted with almost no gap.

Therefore, the elastic arms 51a and 51b are shown in FIG.
When the elastic arm 5 is deformed in the direction (i), the elastic arm 5 is supported by using the portion of the hinge connecting portion B where the support pin C is provided as a fulcrum.
The tip portions 51c and 51d of the la and 51b are deformed in the (ii) direction of FIG. That is, the tip portions 51c and 51d are deformed in the (ii) direction with the base end on the hinge connection portion B side as a fulcrum. As a result, the tip portions 51c and 51d and the small protrusions A provided on this portion slide in the x direction with respect to the support surface 33a. Since the small protrusion A slides on the supporting surface 33a with the smallest contact area, and the portion of the supporting surface 33a on which the small protrusion A slides is a roughened surface E of a minute uneven surface,
The small protrusion A and the support surface 33a slide with a minimum contact area, and the tip portions 51c and 51d and the support surface 33a do not slide in a close contact state as in the conventional case. Therefore, no sliding noise is generated and it is possible to prevent noise when the push button 21 is pressed.

If the small protrusions A are provided on the sides of the tip portions 51c and 51d, it is possible to prevent the generation of sliding noise even if the supporting surface 33a is not formed with fine irregularities and is smooth. If the sliding surface 33a is provided with a roughened surface E having fine irregularities, on the contrary, if the sliding surfaces 33a are provided with the roughened surfaces E, the tip portions 51c and 51d having no small projections A are provided.
Even when the entire surface of the above slides on the support surface 33a, it is possible to prevent the generation of sliding noise. However, in order to prevent the sliding noise more effectively, it is preferable that the support surface 33a is provided with the roughened surface E and the tip portions 51c and 51d are provided with the small projections A.

When the pressing force of the push button 21 is removed,
The push button 21 returns due to the elastic restoring force of the elastic arms 51a and 51b and the restoring force of the switch S. In addition, the sliding operation of the tip of the elastic arm is performed by the other push buttons 22, 23, 24.
The same is true for. However, the second push button 22 is provided with only one elastic arm 52, but as described above, the elastic arm 52 is thicker than the elastic arm 51a or 51b of the first push button 21, and therefore has the same size. Sano push buttons 21 and 22
When you press, the resistance you feel on your fingers is about the same.

On the other hand, although the fourth push button 24 is also provided with only one elastic arm 54, this elastic arm 54 is
The elastic arms 51a and 51b of the push button 21 and the elastic arms 53a and 53b of the third push button 23 have the same thickness. However, the size of the fourth push button 24 is smaller than that of the other push buttons, so that the elastic arm 54 is shorter than the other elastic arms 51a and the like, and the elastic force generated at the time of deformation is large. Therefore, even when one elastic arm 54 having the same thickness as the other is provided, the resistance force felt by the finger when the fourth push button 24 is pressed is the same as when the other push buttons are pressed. Become. Further, as shown in FIG. 3, the operation protrusion 21b is provided at a position deviated from the center of the push button 21 toward the lower side portion (a), and the elastic arms 51a and 51b are arranged from the center of the push button 21. It is provided at a position biased toward the side portion (b) opposite to the side portion (a). Therefore, when the push button 21 is pressed, the restoring force F1 from the switch S acts on the side portion (a) side, and the elastic restoring force F2 of the elastic arms 51a and 51b acts on the side portion (b) side. Since the restoring forces F1 and F2 act on the center of the push button 21 in a well-balanced manner, no matter which position of the push button 21 is pressed by the finger, the push button 21 is pressed uniformly, and the operation feeling becomes good, and further, the switch S will be operated reliably.

Further, as shown in FIG. 3, the elastic arms 51a,
Letting L be the distance at which the tip portions 51c and 51d of 51b contact the support surface 33a, the operation protrusion 21b for pressing the switch S is shown.
Exists within the range of this distance L. That is, the operation protrusion 21b for operating the switch S which is the operation electronic component
Is located within the span L of a portion where the elastic arms 51a and 51b are connected to the push button 21 and a portion where the tip portions 51c and 51d are supported by the support surface 33a via the support pin C. From this, even if the switch S is pushed by the operation protrusion 21b provided at a biased position on the push button 21, a uniform reaction force acts on the push button 21 over the entire upper and lower portions in FIG. Good and push button 21
When is pressed, the push button does not tilt due to a couple.

The support plate 33 is not limited to the one integrally formed with the light guide member 30, and may be another substrate or a part of the nose portion. Further, the push buttons 21 to 24 may not be connected to each other but may be individually separated. Furthermore, the operating device of the present invention is not limited to the on-vehicle audio equipment, but may be other electronic equipment.

[0034]

As described above, according to the present invention, it is possible to prevent the generation of sliding noise when the tip of the elastic arm provided on the push button slides on the support surface.

Also, due to space limitations, even if the portion for pressing the operation electronic component such as the switch is provided deviated from the center of the push button to one side, the elastic piece is provided on the opposite side. By arranging them so as to be biased to the side portions, the reaction force acting on the push button can be evenly distributed, and the feeling of operation can be improved.

Further, even when a pair of elastic arms is provided on one of the adjacent switches and only one elastic arm can be formed on the other switch, by changing the thickness of the elastic arms, the operation reaction of the two push buttons can be prevented. You can use the same force and get the same feeling of operation.
