Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device used in a vehicle-mounted navigation system, a game machine or the like, and in which a plurality of switches are operated by a single operating body.

[0002]

2. Description of the Related Art FIG. 6 is a front view of an operating device in which a plurality of switches are operated by a single operating body, and FIG. 7 is a sectional view thereof. In this operating device, the operating body 2 appears from the window 1a formed in the frame 1. A support shaft 2a is integrally provided in the central portion on the back side of the operation body 2, and the tip of the support shaft 2a is supported by hitting the surface of a substrate 3 provided inside the frame body 1. Pressing portions 2b are integrally formed at four locations on the outer peripheral portion of the back portion of the operating body 2. The board 3 is provided with a switch S that is pressed by each of the four pressing portions 2b. For example, the switch S is of a tact type, and the push button actuator 4 faces the pressing portion 2b.

In this operation switch, a spring for pressing the entire operation body 2 toward the substrate 3 is provided, for example, between the frame body 1 and the flange 2c of the operation body 2. For example, when the position (a) of the operating body 2 is pressed, the operating body 2 rotates counterclockwise as shown by the chain line in FIG. 7 with the contact portion between the support shaft 2a and the substrate 3 as a fulcrum. , (A), the actuator 4 of the switch S located therebelow is pressed by the pressing portion 2b to be operated.

However, in the operating device in which the operating body 2 is inclined with the supporting shaft 2a provided at the center as a fulcrum, the supporting shaft 2a
The distance Lr between the pressing portion 2b and the pressing portion 2b is short, which corresponds to substantially the radial dimension of the operating body 2. Therefore, the inclination of the operating body 2 when the switch S is pressed becomes very large, and the resistance when pressing the operating portion 2 at the portion (a) is large, and the operation feeling when operating the switch S is very large. Get worse. Further, when the switch S is operated, the inclination of the operating body 2 becomes very large, and the operating body from the surface of the frame body 1 at the portion (b) opposite to the portion (b) which is the pressed portion is from the surface. The protrusion size of 2 becomes large, and the appearance of the device during operation is also impaired.

Therefore, a support portion 5 is formed so as to face the flange 2c formed around the operation body 2 from the upper side in the figure over the entire circumference, and the central support shaft 2a is elastically moved in the (c) direction. The operation device supported so as to be movable was examined. In this method, when the portion (a) of the operation portion 2 is pushed, the support shaft 2a can be sunk in the direction (c), so that the flange 2c at the portion (b).
The operating body 2 inclines counterclockwise with the supporting portion 5 supporting the upper part of the above as a fulcrum. The operating body 2 tilts with the right end in FIG. 7 as a fulcrum, so that the distance L1 between the pressing portion 2b pressing the switch S and the fulcrum becomes long, and the switch S is operated by pressing the position (a). The tilt angle of the operating body 2 when the operating body 2 is made shallow, the operability when pressing the operating body 2 is good, and the resistance at the time of pressing can be reduced. Moreover, the part (b) does not significantly project to the front, and the appearance during operation is also good.

[0006]

However, as shown in FIG. 7, in the case where the operating body 2 inclines with the support portion 5 as the fulcrum on the rightmost side and the portion of the support shaft 2a sinks in the (c) direction,
When the switch S at the position (a) is operated, (d)
There is a problem that the pressing portions 2b, 2b located at (e) push the actuator 4 of the switch S.
When the stroke of the pressing portion 2b at that position when the portion (a) is pressed is D, the stroke in the pressing direction of the pressing portions 2b and 2b at the positions (d) and (e) is (L2 /
L1) and D.

In the operating device shown in FIGS. 6 and 7, when the operating body 2 is pushed at the position (a), the position (b) on the opposite side, which is different from that position by an angle of 180 degrees, is a fulcrum. As a result, the operating body 2 tilts. Therefore, the size of L2 is large,
(L2 / L1) also has a relatively large value. for that reason,
When the operating body 2 is pushed in the portion (a), the actuator 4 of the switch S in the positions (d) and (e) is pushed with a somewhat large stroke, and the switch in this position may malfunction. is there.

The present invention is to solve the above-mentioned conventional problems. When a predetermined position of the operating body is pressed, the feeling of pressing the switch at that position is good, and the probability of malfunctioning other switches is increased. It is intended to provide a lowered operating device.

It is another object of the present invention to provide an operating device which makes it easy to operate both switches when pressing an operating body between the switches and operating two adjacent switches together.

[0010]

SUMMARY OF THE INVENTION An operating device of the present invention comprises an operating body operably exposed from a frame body, and a switch which is arranged inside the frame body and which is pressed at four points of the operating body. And an elastic body that elastically supports the operating body so that the entire body can be sunk inside the frame, and an inclined fulcrum of the operating body located on the surface side of the operating body in the middle of the adjacent switches. It is characterized by having.

Further, in the above, when the operating body is pushed in the middle of the adjacent switches, the two adjacent switches are operated together.

According to the present invention, when the operating body is pressed almost directly above the predetermined switch, the operating body is tilted with the intermediate position between the switch and the switch as the tilt fulcrum, and the switch located immediately below the pressed position is pressed. Operated. The other switches located on the side that intersects the switch pressed at this time are
The distance from the tilt fulcrum is shorter than that of the pressure switch. Therefore, when a predetermined switch is pressed, the pressing stroke of the operating body with respect to the other switch at the position intersecting with the predetermined switch is shortened, and the possibility that the other switch malfunctions is reduced.

Next, in this operating device, when the operating body is pressed in the middle of two adjacent switches, the two switches are pressed together and a predetermined input is set. At this time, the tilt fulcrum is located at the opposite position where the angle differs by approximately 180 degrees from the pressed position, and the tilt angle of the operating body becomes shallow, and it becomes easy to simultaneously press the two switches.

The elastic body that supports the entire operating body so that it can sink inside the frame body is an elastically deformable support that supports the center of the operating body, as shown in FIGS. 3 and 4. Alternatively, as shown in FIG. 5, the switch deforming portions 31a to 3 of the elastic sheet 30 forming the switch may be used.
It may be 1d. Alternatively, the elastic body may be a spring built in the tact switch as shown in FIG. 7, and the entire operating body may be elastically supported by the elastic reaction force of the tact switch.

The operating body 20 has a disk-like shape and has a protrusion 2 on the surface.
1a is installed in the housing so as to project from the round window 12. A flange 21b is integrally formed around the operating body 20, and the upper surface of the flange 21b contacts the fulcrum protrusions 14a, 14b, 14c, 14d. A part of the flange 21b is a projecting piece 21c protruding laterally, and this projecting piece 21c is the cutout 1 of the cylindrical rib 13.
Entering inside 3a, the operating body 20 is restricted in the rotational direction.

Operation indicators a, b, c, d, e, f, g and h are provided on the surface of the projection 21a of the operating body 20. Each of these operation indications is the position where the operating body 20 is pushed, and the pushed position is the basic four mutually orthogonal positions.
8 positions in total (a, c, e, g) in each direction and 4 positions (b, d, f, h) in 4 directions arranged at an angle of 45 degrees with respect to each position. is there. When used for remote control of audio equipment, when the position a is pressed, the tape is played in the forward direction, when e is pressed, the tape is played in the reverse direction, when the position c is pressed, the tape is fast-forwarded, and the position g is pressed. Each operation such as rewinding is performed. When it is used for remote operation of the navigation system,
When any one of the items h to h is pressed, the screen is scrolled or the cursor is moved in the pressing direction.

On the back of the operating body 20, there are four pressing portions 2
2a, 22b, 22c and 22d are integrally formed to project. As shown in FIG. 2A, the pressing portions 22a, 22a
b, 22c and 22d are formed directly below the basic four-direction operation displays a, c, e and g. Further, in a state where the operation body 20 is installed on the back side of the frame body 10 and the projecting piece 21c is fitted in the notch 13a, the fulcrum projection 14a,
The positions where 14b, 14c, and 14d contact the flange 21b are the positions of the operation displays b, d, f, and h. That is, the fulcrum protrusions 14a, 14b, 14c, 14d are the positions where the flanges 21b abut, that is, the inclined fulcrums of the operating body 20, are the four pressing portions 22a, 22b, 22c, 2.
It is the angular position that is the midpoint of two adjacent objects of 2d.

Inside the frame 10, an elastic sheet 30 and a printed board 40 are provided on the back side of the operating body 20. The elastic sheet 30 is formed of an elastic material such as silicon rubber. The elastic sheet 30 is provided with an elastically deformable support portion 32, and the support hole 23 formed in the central portion of the back surface of the operating body 20 is fitted in the support portion 32. In the elastic sheet 30,
Switch deforming portions 31a, 31b, 31c, 31d are integrally formed at four locations around the support portion 32, and the switch deforming portions 31a, 31b, 31c, 31d.
Conductor layers 33 such as carbon are provided on the lower surfaces of the respective. Each pressing portion 22 formed on the operating body 20
a, 22b, 22c, and 22d are each switch deformation part 31.
It abuts on the upper surface of a, 31b, 31c, 31d. When the operating device is assembled, FIG.
As shown in (A), the operating body 20 includes an elastically deformable support portion 32 and switch deformable portions 31a, 31b, 31.
The flange 21b of the operating body 20 is elastically pressed toward the frame body 10 while being supported by the c and 31d, and the flange 21b of the operating body 20 is attached to the fulcrum protrusions 14a,
It is in a state of being pressed by 14b, 14c, 14d. Further, since the operating body 20 is elastically supported by the elastic sheet 30, the entire operating body 20 is supported so as to be able to sink toward the printed circuit board 40. That is, in this example, the support portion 32 and the switch deforming portions 31a to 31d.
Both of them function as elastic bodies that support the operation body 20 so that it can be sunk inside the frame body.

On the surface of the printed circuit board 40, four sets of contact points 41 and 42, which are formed in a comb shape and face each other, are formed by a conductive foil pattern. The elastic sheet 30
The conductor layers 33 provided on the switch deforming portions 31a, 31b, 31c, 31d face above the contacts 41 and 42 of each set, and four switches S1, S2, S3, S4 are formed. There is.

Next, the operation of the operating device will be described. As shown in FIGS. 3 and 4, the frame 10 and the printed circuit board 40 are kept at a constant distance. An elastic sheet 30 is interposed between the frame body 10 and the printed circuit board 40, and the central portion of the operating body 20 is supported from the back by a supporting portion 32 formed on the elastic sheet 30, and at four positions. The pressing portions 22a, 22b, 22c, 22d are the switch deforming portions 31a, 31b, 31c, 31 of the elastic sheet 30, respectively.
It is pushed by d from the back side. Therefore, the operating body 20
The flange 21b of the fulcrum is the fulcrum projections 14a, 14 of the frame 10.
b, 14c, 14d, and in this state,
Each switch deformation part 31a, 31b, 3 of the elastic sheet 30
The conductor layer 33 formed on 1c and 31d is separated from the contacts 41 and 42 of the printed circuit board 40, and the switches S1 and S
2, S3 and S4 are all off.

FIGS. 3A and 3B show the operation when the operating body 20 is pressed directly above the switch. For example, the operation display g of the operating body 20 is pressed and the switch is pressed. S
This is an operation for turning on 4. In this operating device, as described above, the operating body 20 is pressed toward the frame 10 by the elastic sheet 30, and the operating body 20 is elastically supported so that the entire operating body 20 can be sunk toward the printed circuit board 40. Has been done. Therefore, when the operating body 20 is pressed in any part of the operation display, the operating body 20 tilts with the contact portion with any of the fulcrum protrusions formed on the frame body 10 as the tilt fulcrum.

In FIG. 3, when the portion of the operation display g is pressed, the tilt fulcrum of the operating body 20 is the fulcrum projections 14a and 1a.
4b, the fulcrum protrusion 14a is at the midpoint of the pressing portions 22a and 22b, and the fulcrum protrusion 14b is the pressing portions 22b and 22b.
It is the position of the midpoint of c. As shown in FIG. 3 (B), when the portion of the operation display g is pressed, the operating body 20 inclines with two abutting portions of the two fulcrum protrusions 14a and 14b and the flange 21b as inclination fulcrums. Then, the switch deforming portion 3 of the elastic sheet 30 is pressed by the pressing portion 22d of the operating body 20.
1d is pressed, the conductor layer 33 formed on the switch deforming portion 31d contacts the contacts 41 and 42 of the printed board 40, and the switch S4 is turned on. At this time, as shown in FIGS. 2A and 3A, the tilt fulcrum (the fulcrum protrusion 14
a and 14b) to the pressing portion 22d in a linear distance (III
-Distance on the III cross section) is La1 and is 2 from the tilt fulcrum.
The distance between the two pressing portions 22a and 22c is Lb1.

First, with respect to the pressing portion 22d, since the distance La1 from the inclined fulcrum (fulcrum protrusions 14a, 14b) is relatively long, the operability when pressing and deforming the switch deforming portion 31d by the pressing portion 22d is good. is there. That is, in the case of tilting with the central support shaft 2a as a fulcrum like the conventional example shown in FIG. 7, the distance Lr from the tilt fulcrum to the switch pressing portion is short, and the tilt angle of the operating body when the operating body is pressed is small. Therefore, a large force is required when pushing the operating body, and the feeling of operation becomes poor. In contrast, FIG.
In (B), since the operating body 20 is inclined with the fulcrum protrusions 14a and 14b as the inclination fulcrum and the distance La1 from the inclination fulcrum to the pressing portion 22d is long, the operation of the switch S4 can be performed with a light force, and the operation body 20 can be operated. Since the inclination angle is small, the operability is also good.

As shown in FIG. 3B, the operating body 2
When the g portion of 0 is pushed and tilted with the fulcrum protrusions 14a and 14b as the tilt fulcrum, the pressing portion 22d pressed by the finger
The two pressing portions 22a and 22c located at a position orthogonal to are also moved in the direction of the substrate 40, and the switch deforming portions 31a and 31c located at that position are pushed. However, III-III
Since the fulcrum protrusions 14a and 14b are close to the center of the operating body 20 in the plane direction of the cross section, the distance Lb1 from the inclined fulcrum to the pressing portions 22a and 22c becomes short. Therefore, the ratio of the distance La1 from the tilt fulcrum to the pressing portion 22d and the distance Lb1 to the pressing portions 22a and 22c (Lb1 / La
1) becomes small, and the pressing portion 22d becomes the switch deforming portion 31.
When the stroke when pressing d is D, the other two pressing parts 22a and 22c are the switch deforming parts 31a and 31c.
Stroke when pressing c (Lb1 / La1)
D does not grow very large. Therefore, even when the switch deforming portion 31d comes into close contact with the printed circuit board 40 in FIG. 3B, the other two switch deforming portions 31a, 31
c (indicated by a dotted line 31a) is the printed circuit board 4
It is far away from 0 and the two switches S1 and S3 are never turned on.

FIG. 2B shows a comparative example with respect to the present invention. In this comparative example, the operating tool 2 is displayed at the operation display g.
The case where the tilt fulcrum (i) when 0 is pushed is located on the flange 21b on the outer circumference of the pressing portion 22b on the opposite side. In this case, the pressing portion 22 is moved from the tilt fulcrum (i).
The ratio of the distance La2 to d to the distance Lb2 from the tilt fulcrum (i) to the other two pressing portions 22a and 22c (Lb2 /
La2) becomes a large value, and when the pressing portion 22d presses the switch deforming portion 31d, the other two pressing portions 22a are pressed.
There is a risk that the stroke (Lb2 / La2) · D of the switch deforming parts 31a and 31c pressing the switch deforming parts 31a and 31c becomes large and the switch deforming parts 31a and 31c come into contact with the printed circuit board 40 and the switches S1 and S3 malfunction.

As can be seen from the comparison with this comparative example, in the present invention, since the fulcrum protrusion serving as the tilt fulcrum is provided in the middle of the adjacent switch (pressing portion), the operating body 20 is located directly above the switch. When pressed, other switches do not malfunction. Note that this is not limited to the case where the operation body 20 is pressed at the operation display g portion, and the operation display a,
The same applies when the operating body 20 is pressed at each of the portions c and e.

Next, in the operating device of the present invention, when the operating body 20 is pushed in the middle of the adjacent switches, the adjacent two
Both of the two switches are turned on, and a predetermined input is detected by turning on these two switches.
For example, as shown in FIG. 4B, when the operating body 20 is pressed in the operation display f portion, the pressing portions 22 located on both sides of the operating body 20 are pressed.
The switch deforming portions 31c and 31d are pressed by c and 22d, and the conductor layer 33 of both switch deforming portions 31c and 31d is pressed.
Contacts the contacts 41 and 42 of the printed circuit board 40, and the switches S3 and S4 are turned on together. Switches S3 and S
When both 4 are turned on, for example, on the screen of the display device, the display map on the screen is scrolled in the direction of f.

As shown in FIG. 2A, when the operating body 20 is pushed at the portion of the operation display f, the fulcrum protrusion 14a located on the opposite side thereof serves as an inclined fulcrum when the operating body 20 is inclined. . Therefore, the distance Lc1 from the tilt fulcrum (fulcrum protrusion 14a) to the two pressing portions 22c and 22d becomes considerably long. Since the distance Lc1 can be secured long, the switch deforming portion 31 is formed by the two pressing portions 22c and 22d.
The operation resistance when pressing c and 31d becomes small, and the operation becomes easy. On the other hand, in the comparative example shown in FIG. 2 (B), when the operating body 20 is pushed at the portion of the operation display f, the tilt fulcrums are at the positions (i) and (ii), and two pushes are made from this tilt fulcrum. Since the distance between the portions 22c and 22d is short, the operability for simultaneously pressing both pressing portions 22c and 22d becomes poor.

Further, as shown in FIG. 2A, in the present invention, when the operating body 20 is pushed by the pressing portion 22d, for example, the inclined fulcrums become the fulcrum protrusions 14a and 14b, and the pressing force acts. A point (that is, a pressing point that deforms the switch deforming portion) and each tilt fulcrum are arranged in a triangle. Further, when the operation body 20 is pushed in the middle of the pushing portion, for example, the portion of the operation display f, the pushing portion for pushing the switch deforming portion is 22c.
22d and 22d, the tilt fulcrum becomes the fulcrum protrusion 14a, and in this case also, the pressing point of the switch deforming portion and the tilt fulcrum have a triangular relationship. On the other hand, in the comparative example shown in FIG. 2B, when the operation display g is pressed, the pressing portion 22d and the tilt fulcrum (i) are located on a straight line, and when the operation display f is pressed, two The relationship between the pressing portions 22c and 22d and the two tilt fulcrums (i) and (ii) is a quadrangle. As described above, in the present invention, the point of action of the force on the operating body is always a triangle both when the operating body 20 is pressed directly above the pressing portion and when the operating body is placed in the middle of the pressing portion. Therefore, the operation is stable, and the operability is good.

Next, FIGS. 5A and 5B are cross-sectional views of another remote controller using the operating device of the present invention. FIG.
4A and 4B are cross-sectional views corresponding to FIGS. 4A and 4B, and are cross-sectional views taken along line IV-IV in FIG. 2A. In the remote control device in this example, the central portion of the back surface of the operating body 20 is not supported by the elastic sheet 30, and the pressing portions 22 at four locations are included.
Only a to 22d are the switch deformation part 31 of the elastic sheet 30.
By contacting a-31d and being pushed from the back side,
1 to 4 show that the operating body 20 is pressed in the direction of the frame 10 and that the contact shaft 20a extends from the central portion of the rear surface of the operating body 20 toward the printed circuit board 40. 1 is different from the remote control device shown in FIG.
~ It is the same as the above-mentioned remote control device shown in FIG. That is, in the example shown in FIGS. 5A and 5B, the elastic sheet 30
The switch deforming portions 31a to 31d function as elastic bodies that support the operation body 20 so that the entire operation body 20 can sink.

The abutting shaft 20a has a spherical tip, and as shown in FIG.
When no operating force is applied to the contact shaft 20 a, the tip of the contact shaft 20 a is separated from the printed circuit board 40. And FIG.
When the portion of the operation display f of the operating body 20 (see FIG. 2A) is pressed as shown in (B), the operating body is set with the fulcrum projection 14a as an inclined fulcrum as in the remote control device shown in FIGS. 20, the switch deforming portions 31c and 31d are simultaneously pressed by the two pressing portions 22c and 22d, and the switches S3 and S4 are turned on together.

Immediately after the switches S3 and S4 are switched from OFF to ON, that is, the switch deforming section 31c.
And the conductor layer 33 of 31d is the contact point 41 of the printed circuit board 40.
And 42, and slightly from that position
The length of the contact shaft 20a is set so that the tip of the contact shaft 20a contacts the printed circuit board 40 when 0 is pushed. Therefore, the operating body 20 is not pushed in more than necessary, and for example, the four switches S1 to S4 are
It is possible to prevent a problem that three or more switches are turned on at the same time.

When one switch is turned on,
For example, when the portion of the operation display g of the operation body 20 (see FIG. 2A) is pressed, the two fulcrum protrusions 14a and 14b
The operating body 20 is tilted with the tilt fulcrum as a fulcrum, and the switch deforming portion 31d of the elastic sheet 30 is pushed by the pressing portion 22d. At this time, as is apparent from FIG.
Ratio of distance La1 from a, 14b to pressing portion 22d and distance Lb1 to central portion of operating body 20 (Lb1 / La1)
Is the ratio of the distance Lc1 from the fulcrum protrusion 14a to the pressing portions 22c and 22d and the distance Ld1 from the fulcrum protrusion 14a to the central portion of the operating body 20 when the two switches S3 and S4 are simultaneously turned on (Ld1 / Since the contact shaft 20a is smaller than Lc1), the contact shaft 20a does not sink so much that the contact shaft 20a does not contact the printed circuit board 40.

In this way, the central portion of the rear surface of the operating body 20 is
Printed circuit board 4 when two switches are turned on at the same time
By providing the contact shaft 20a having a length for contacting with 0, not only the same operation and effect as the remote control device shown in FIGS. 1 to 4 are achieved, but also the central portion of the surface of the operating body 20 is pushed in mischievously. Even in this case, it is possible to prevent three or more switches from being turned on at the same time, and it is possible to prevent the input detection circuit of the switch from malfunctioning. In the above embodiment, the fulcrum protrusion serving as the tilt fulcrum is provided on the frame body side.
A fulcrum protrusion may be formed at a location, and the fulcrum protrusion may be in contact with the frame body to form an inclined fulcrum.

Further, the abutting portion between the fulcrum protrusion serving as an inclined fulcrum and the operating body may be formed of an elastic body such as rubber. In this structure, for example, as shown in FIG. 3B, when the operation body 20 is pressed directly above the pressing portion 22d and the switch deforming portion 31d is pressed by the pressing portion 22d, the tilt fulcrum (the fulcrum protrusion 14a). And 14b) elastically contract slightly, and the operating body 20 can project in the direction of projecting from the frame body 10 (away from the printed circuit board 40) at the inclined fulcrum portion, so that the pushing parts 22a and 22b push it. The switch deforming portions 31a and 31c are easily separated from the printed board 40, and the effect of preventing the malfunction of the switches S1 and S3 is enhanced.

Further, the switch operated by the pressing portion of the operating body 20 may be a tact switch as in the conventional example shown in FIGS. 6 and 7. In this case, a contact shaft 20a shown in FIG. 5, for example, is provided at the center of the operating body 20. In this example, a built-in spring or the like that exerts an operation reaction force of the tact switch serves as an elastic body that supports the operating body 20 so that the operating body 20 can be sunk.
