In addition, three engaging protrusions 64 for engaging with the holding arms 82 of the chassis 80 are provided on the outer periphery of the middle plate 60 at positions 90 degrees from the center. In addition, on the outer periphery of the middle plate 60 , an engaging concave portion 66 to be engaged with the mounting arm 13 of the round key 10 is disposed opposite to each other across the center.

The base unit 4 is mainly composed of a dome switch unit 70 , an adhesive unit 75 , and a base 80 .

The dome switch portion 70 is formed in a substantially disc shape, and the five dome switches 72 are arranged at the center and at 90 degrees relative to the center like five eyes of a dice. Such an arrangement is mainly used for pressing operations at five positions of the center, front, rear, left, and right, or five positions of the center, up, down, left, and right, in a user interface that is press-operated in a device equipped with the multifunctional operation switch 1 .

In addition, the four dome switches 72 arranged around the center other than the center are provided at positions corresponding to the four capacitance detection protrusions 36 provided on the capacitance sensor drive unit 30 . That is, when viewed from the center of the operation portion 2, four substantially arc-shaped capacitive detection protrusions 36 arranged at an angle of 90 degrees to each other correspond to the same direction. A dome switch 72. Accordingly, in capacitance detection using the capacitance detection convex portion 36 , it is possible to detect up, down, left, and right, and front, rear, left, and right with high precision.

The adhesive part 75 is a member for affixing a double-sided tape to both the front and back surfaces of the disk-shaped PET. Thereby, the back surface of the dome switch part 70 and the surface of the base 80 can be firmly and easily fixed.

The base 80 is formed of a metal member, and two mounting portions 82 are provided on the outer periphery of a disk-shaped plate portion 81 . The mounting portions 82 are arranged to face each other across the center.

By assembling the components thus constituted, the multifunctional operation switch 1 shown in the perspective view of FIG. 3 is completed.

At this time, each part presses the round key 10 and the center key 20, the top plate 25, the capacitance sensor driving part 30, the capacitance detection part 41, the adhesive part 55, the middle plate 60, the dome switch part 70, the circle The top switch detection part 51, the adhesive part 75, and the base 80 are assembled in this order.

At this time, the connection portion 50 of the substrate portion 40 is bent in a conductive state, therefore, the capacitance detection portion 41 is sandwiched by the capacitance sensor drive portion 30 and the adhesive portion 55, and the dome switch detection portion 51 is formed by the dome switch portion 70 and the bonding portion 55. The base 80 holds it. Thereby, the detection result by the capacitance detection part 41 and the dome switch part 70 is easily conveyed.

In addition, the operating part 2 is biased in a direction away from the middle part 3 by the elastic force of the capacitive sensor driving part 30, and the tip of the mounting arm 13 abuts against the back side of the engaging concave part 66, thereby being positioned, and will not Go further away. That is, the capacitive sensor drive unit 30 in the portion where the operation portion 2 is allowed to be pressed toward the middle portion 3 and the pressing force is applied detects a change in capacitance.

The middle part 3 utilizes the elastic force of the dome switch 72 to apply a force in the direction away from the base part 4, and inserts the engaging protrusion 64 through the engaging hole of the holding arm 82 and abuts against it, so that it is positioned so that it will not go any further. leave. That is, the middle part 3 is allowed to be pressed toward the base part 4, the pressing force is applied to the dome switch 72 closest to the unpressed part of the operation part 2, and switch ON due to the reverse rotation of the dome switch 72 is detected.

The change of the electric capacity of capacitive sensor driving part 30 detected like this and the switch ON of dome switch 72, from connection interface 45 through connection terminal 46 to other equipment (for example mobile phone, digital camera, personal computer, PDA, TV, video recorder, or remote control device, etc.) output.

4 is a longitudinal sectional view of the multifunctional operating switch 1, FIG. 5 is a perspective view of the longitudinal section of the multifunctional operating switch 1, and FIG. 6 is an enlarged sectional view of part A-A of FIG. 4 .

As shown in the longitudinal sectional view of FIG. 4 , the IC protection protrusion 14 is formed higher than the IC 44 , and is separated from the base 41 in a state where no pressing operation is performed. This separation distance is formed so as not to affect the pressing operation of the circular operation part 11 . That is, this separation distance is greater than the maximum stroke by which the circular operation part 11 sinks by the pressing operation.

In addition, the dome switch pressing protrusion 62 of the middle plate 60 is arranged at a position facing the center (apex) of each dome switch 72 . When the circular operation part 11 is pressed, the load mainly acts on the dome switch 72 closest to the pressed operation part, and when the load exceeds a predetermined value, the metal bending plate of the dome switch 72 reverses, Switch ON is detected.

The center key 20 is held by the center key holding portion 33 , and the pressing protrusion 35 in the center of the back surface of the center key holding portion 33 is arranged at a position facing the center (vertex) of the center dome switch 72 . When the center key 20 is pressed, the center key holder 33 deforms, and the pressing protrusion 35 presses the central dome switch 72. When the load exceeds a predetermined value, the dome switch 72 reverses to detect switch ON.

As shown in FIG. 6 , the capacitance detection convex portion 36 on the back surface of the capacitance sensor drive unit 30 is in contact with the surface of the capacitance detection unit 41 of the substrate unit 40 . Electrode portions 41 a that are energized and non-conductive portions 41 b that are not energized are provided near the surface of the capacitance detection portion 41 , and their entire surfaces are covered with an insulating tape (not shown).

In the capacitance detection convex portion 36 , the lower convex portion 36 a on the outer peripheral side and the lower convex portion 36 c on the inner peripheral side are formed at the same height, and an inclined portion 36 b is provided therebetween. The inclined portion 36b is inclined such that the thickness of the capacitive sensor drive unit 30 becomes gradually thinner from the lower convex portion 36a toward the lower convex portion 36c. According to this configuration, between the inclined portion 36 b of the capacitance detection convex portion 36 and the surface of the capacitance detection portion 41 , a triangular minute space E whose height gradually becomes narrower from the center toward the outer periphery is formed.

An annular plate 31 which is a metal member is provided on a surface of the capacitive sensor drive unit 30 opposite to the capacitive detection convex portion 36 . The pressing protrusion 15 provided on the back surface of the circular key 10 of the operation unit 2 abuts on the surface of the annular plate 31 . The annular plate 31 is a substantially horizontal flat ring.

According to this configuration, when the circular key 10 of the operation unit 2 is pressed and operated, the pressing protrusion 15 presses the annular plate 31 of the capacitive sensor driving unit 30 . At this time, since the annular plate 31 is a hard metal member and is a substantially horizontal flat ring, the annular plate 31 presses the capacitive sensor drive unit 30 with its surface straight.

The convex portion 36 for capacitance detection of the capacitive sensor drive unit 30 is deformed by the pressing force of the annular plate 31 , the inclined portion 36 b approaches the capacitance detection unit 41 , the micro space E is further reduced, and the capacitance changes continuously in a simulated manner.

Therefore, the capacitance detection unit 41 can sensitively and continuously detect changes in the capacitance.

The capacitance detection convex portion 36 of the capacitance sensor drive unit 30 is configured to deform with a weak pressing force smaller than the pressing force required for the dome switch 72 until the switch is turned ON. Therefore, a change in capacitance of the dome switch 72 before and after the switch is turned ON can be detected.

In addition, as shown in FIG. 6 , the dome switch 72 is arranged outside the center of the pressing force direction detection unit (the capacitance sensor drive unit 30 and the capacitance detection unit 41 ). As a result, when a part of the circular key 10 of the operation unit 2 is pressed and swung, the dome switch 72 is positioned close to the outer periphery of the circular key 10 whose pressing stroke is the longest.

FIG. 8 is a front view of a digital camera 90 including a multi-function operation switch 1 . The digital camera 90 is provided with a shooting start shutter button 92 on the right side of the upper surface, and a photographing lens is provided on the rear side (not shown).

A display 91 is provided on the front of the digital camera 90 , and a multifunctional operation switch 1 is provided laterally adjacent to it on the right side. The multifunctional operation switch 1 is used as a switch for setting shooting conditions and the like of the digital camera 90 , a switch for selecting stored photographs, and the like. A menu button 93 for displaying a menu screen or the like on the display 91 is provided above the multifunction switch 1 , and a playback button 94 for displaying captured images is provided below the multifunction switch 1 .

The digital camera 90 includes, as a structure not shown, an image acquisition unit such as a CCD or CMOS that executes photographing processing, an illumination unit that emits light from a strobe, a drive unit that performs driving such as focus adjustment and zooming, a storage unit that stores photographed images, etc., and a control unit that executes various control actions.

According to the above structure, the multifunctional operation switch 1 can detect various operations.

If described in detail, then, as shown in the capacitance explanatory diagram of FIG. side) to detect changes in capacitance. Here, the arrows shown in the figure indicate the detection direction and detection level, and the bars A to D provided in the lower part of FIG. .

As shown in FIG. 7(B), for example, when the right side of the circular key 10 in plan view is pressed with a force smaller than that in the example of FIG. 7(A), the output becomes smaller.

In addition, as shown in FIG. 7(C), when a position between A and B (for example, upper right or front right) in the circular key 10 is pressed, the two capacitance detection protrusions 36 of A and B detect a change in capacitance. Therefore, the amount of change in capacitance is the sum of the two amounts of change in A and B. As shown in FIG. direction.

In this way, the pressing force and direction of the circular key 10 can be sensitively and continuously detected by the pressing force direction detecting unit (capacitance sensor driving unit 30 and capacitance detecting unit 41 ), so various inputs can be detected. For example, when tracking is performed so as to rotate the surface of the round key 10 , it can be detected that the direction of the vector continuously changes and the rotation operation is performed, and therefore, it can be used for input corresponding to the rotation operation. In addition, an operation such as a light tap can also be detected.

In addition, when the pressing force for pressing the circular key 10 is made stronger or weaker, the strength can be continuously detected, so that an operation input corresponding to the pressing force can be accepted.

In addition, not only the four orientations of up, down, left, and right, and front, rear, left, and right, but also 360-degree omnidirectional detection can be performed based on the composite vector generated by the four capacitance detection convex parts 36, so that various direction inputs can be performed.

In addition, the intensity and direction of pressing with a pressing force weaker than the pressing force required for detection of the dome switch 72 can be continuously detected in minute units. Therefore, for example, it can be used as a pre-detection before the dome switch 72 is firmly pressed and detected. In this case, for example, on the display screen of the display 91, corresponding to the four surrounding dome switches 72, four buttons positioned up, down, left, right, front, back, left, and the like are displayed, and when the pressing force direction detection unit (capacitive sensor driving unit 30 When the capacitive detection part 41) detects a small press, the button corresponding to the direction of the pressed detection is changed to display the luminous display, indicating that it is being selected; If the change is further pressed firmly and when the switch ON is detected by the dome switch 72, the color will be displayed, and the corresponding button will be selected and confirmed. In addition, when the pressure is weakened before the dome switch 72 is turned ON, the brightness of the light-emitting display can be reduced or the size can be slightly changed.

In addition, the dome switch 72 can be used to detect the situation of pressing hard, and at this time, the click feeling caused by the reverse rotation of the dome switch 72 can be obtained, so that a good operating feeling can be provided.

In addition, the multi-function operation switch 1 is a two-stage structure that performs stepless detection of the pressing force direction detection part (capacitance sensor drive part 30 and capacitance detection part 41) and detection of the dome switch 72, and is compared with a rotary type. The conventional example of the dial can be made thinner and smaller as a whole.

In addition, by excluding the physical rotation structure, the rotation operation input can also be detected through the direction detection by the pressing force direction detection unit (capacitance sensor drive unit 30 and capacitance detection unit 41), so that parts generated in the rotation structure can be prevented. Faults such as wear, loose parts, tilt, and abnormal noise. Therefore, good operability can be maintained over a long period of time. In addition, it is also possible to eliminate the strict component tolerance management required by conventional rotating structures, and to manufacture parts with lower precision than conventional ones.

In addition, the number of components and the number of assembly steps can be reduced by using the structure without a rotating structure and the structure of the board part 40 that connects the capacitive detection part 41 and the dome switch detection part 51 in two layers by bending the connecting part 50. , Reduce the number of parts management.

In addition, in the above-mentioned embodiment, the operation part 2 is configured so that the circular key 10 and the central key 20 operate independently, but the central key 20 may not be provided and may be constituted by a single disk-shaped key. In this case, the center dome switch 72 may be omitted. In this case, it is also possible to detect various types of operation inputs such as up, down, left, and right, front and rear, left and right, oblique directions, and rotation operations, and pressing intensity inputs due to changes in pressing force.

In addition, the IC protection protrusion 14 is provided on the back side of the circular operation part 11 of the circular key 10 , but is not limited to this, and may be provided on the surface of the capacitance detection part 41 near the IC 44 . Also in this case, damage of IC44 can be prevented.
