DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite operation type electric component having both a function as a rotary operation type electric component and a function as a push operation type switch.

[0002]

2. Description of the Related Art As a prior art of this kind of composite operation type electric component, there is, for example, a configuration disclosed in Japanese Utility Model Registration No. 2555484.

[0003] Such a conventional composite operation type electric component includes a mounting plate on which a sliding pattern portion of a flexible substrate is placed,
Between the support case provided with a pressing protrusion protruding downward,
The mounting plate and the support case, which incorporate a slider receiver having a rotating shaft extending to the side and having a slider mounted on one side and slidingly contacting the sliding pattern portion, and integrating the rotating shafts with each other. A rotary knob is fixedly attached to the rotating shaft, and further, a push button switch provided in a routing portion of the flexible substrate is disposed on an inner bottom surface of a holding member that holds these members movably up and down. ,
The click spring (tact spring) of the push button switch is opposed to the pressing projection.

Therefore, the slider can be slid on the sliding pattern portion by rotating the rotary knob. For example, if a resistor pattern is formed on the sliding pattern portion, the resistance output is reduced. The value can be changed, and a function as a rotary operation type variable resistor can be obtained. Further, since both ends of the rotating shaft of the slider receiver are inserted into the guide holes of the holding member, and the pressing projections of the support case are supported by the holding member via a return means such as a leaf spring, By pressing the rotary knob downward against the elastic force of the return means, the support case can be moved downward and the click spring can be inverted by the pressing protrusion, so that the push button switch with a click feeling The function can be switched from off to on, and a function as a push-operation switch can be obtained.

By the way, in the above-mentioned prior art, both ends of a rotary shaft of a rotary component formed by integrating a rotary knob and a slider receiver are slidably engaged with guide holes of a holding member, respectively. The rotating parts and the movable parts such as the support case and the mounting plate can be slid (moved up and down) at the time of pressing operation. However, if such a guide mechanism is adopted, a pair of side plates having guide holes in the holding member is provided. And the movable part must be disposed between the pair of side plates, which makes it difficult to reduce the thickness of the entire electric component. In particular, recently, it has often been impossible to secure a large space between the housing of this type of composite operation type electric component and the front surface of the rotary knob (the side end surface on the side opposite to the slider). From the viewpoint of accelerating, it is difficult to say that a mechanism for guiding both ends of the rotating shaft is preferable.

On the other hand, in the composite operation type electric component disclosed in Japanese Patent Application Laid-Open No. HEI 8-185754, a guide portion is provided on the rear surface of a mounting plate, and the guide portion is attached to a holding member (support base). Since it is slidably engaged with the guide rail of the upright column, there is no need to provide a guide mechanism on the front side of the rotary knob, and therefore, it is easier to achieve a desired reduction in thickness as compared with the prior art.

[0007]

SUMMARY OF THE INVENTION The above-mentioned JP-A-8-1
In the composite operation type electric component described in Japanese Patent No. 85764, a shaft (supporting shaft) protruding from a mounting plate is inserted into a center hole of a rotary knob, and the shaft can rotate the rotary knob from a radially inner side. Although it is configured to support, since the rotation knob of such a support structure easily causes backlash with the shaft portion,
If the guide mechanism at the time of pressing operation is provided on the back side of the mounting plate, the rotary knob pushed by the operator causes a slight inclination of the mounting plate via the shaft portion, and this inclination is caused by the guide mechanism. There is a problem that smooth slide movement is easily hindered.

[0008]

According to the present invention, there is provided a composite operation type electric component having both a function as a rotary operation type electric component and a function as a push operation type switch, wherein a rotary knob and a slider receiver are integrated. A cylindrical rotating shaft of the rotating component is supported from the radial inside by the insertion protrusion of the mounting member, and is supported from the radial outside by the inner peripheral portion of the bearing member integrated with the mounting member. And a guide projection slidably engaged with a rail section of the holding member provided on the back side of the mounting member, and the rail section and the guide projection are connected to a movable part (a rotating part, a mounting member, a bearing, etc.) at the time of pressing operation. Member). Such a composite operation type electric component is
Since the rotating shaft of the rotating part is supported from the radially inner side and the radially outer side, play is less likely to occur, so that there is no fear that the rotating knob may undesirably tilt the mounting member during the pressing operation, and the movable part part is always It can be slid smoothly.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In a composite operation type electric component according to the present invention, by rotating a rotary knob, a slider that rotates integrally with the rotary knob slides on a sliding pattern portion, and By pressing the rotary knob in a predetermined direction substantially orthogonal to the axis, a movable part including the rotary knob moves in the same direction against the resilient force to operate a push button switch, thereby operating a push button switch. A rotating part having a cylindrical rotary shaft, wherein a slider receiver having the slider mounted on a surface facing the sliding pattern portion is integrated with the rotary knob; Has a support wall portion on which is mounted, and an insertion protrusion that supports the rotary shaft from the radial inside is projected from a surface of the support wall portion on the side of the sliding pattern portion, and the support wall portion has A mounting member with a guided projection protruding from the opposite surface, A bearing member that is integrated with the mounting member and has an inner peripheral portion that axially supports the rotating shaft from the outside in the radial direction and a rail portion extending along the predetermined direction are erected and the rail portion is guided by the mounting member. A holding member to be slidably engaged with the protrusion, and a flexible substrate provided with the sliding pattern portion and the push button switch portion, wherein the holding member is provided with the rotating component via the rail portion and the guided protrusion. The movable component section including the mounting member and the bearing member is slidably held in the predetermined direction.

[0010] In the composite operation type electric component configured as described above, the rotary shaft of the rotary component such as the rotary knob is supported by the insertion protrusion of the mounting member and the inner peripheral surface of the bearing member from both inside and outside in the radial direction. As a result, it is easy to prevent backlash of the rotating shaft, which would induce inclination of the rotating knob. Therefore, the rotation knob pushed by the operator is less likely to be tilted due to the backlash, and adversely affects the guide mechanism when the rotation knob tilts the mounting member, that is, rotation during the pressing operation. The problem that the guided projection is hooked on the rail portion due to the inclination of the knob can be easily avoided. Therefore, such a composite operation type electric component can smoothly slide the movable component portion at the time of pressing operation, and furthermore, since a guide mechanism is not required on the front side of the rotary knob, it is easy to achieve a desired thickness reduction. The rotary knob can be arranged close to the housing of the electronic device product in which the operation type electric component is incorporated.

In addition, a pair of the rails extending substantially parallel to each other and having their leading ends connected to each other are provided on the holding member, and a pair of the mounting members are disposed inside the pair of the rails. If the guided projections are provided and these guided projections are configured to be engaged with the different rail portions, there is no danger that the guided projections will fall off the rail portions, and the movable component portion will be further smoothed. Can be slid.

If an O-ring coated with grease is interposed between the outer peripheral portion of the bearing member and the rotary knob, not only the inner peripheral portion but also the outer peripheral portion of the rotating component can be rotatably supported. Therefore, the inclination of the rotary knob can be prevented more reliably, and a desired operation resistance can be generated at the time of the rotation operation by the grease applied to the O-ring. It is possible to make it difficult to cause a problem that the motor rotates unexpectedly.

The holding member 13 is made of a synthetic resin different from the mounting member 7, for example, an ABS resin. As shown in FIGS. 24 to 28, a pair of rail portions 14a extending in the vertical direction are connected at the upper ends by connecting portions 14b. And a pedestal portion 15 having a pressing projection 15a and a pair of claw pieces 15b protruding from the upper surface thereof.
Reference numeral 4 stands substantially vertically. The pedestal portion 15 has a pair of through holes 15c for releasing the guide projections 7j projecting downward from the bottom plate portion 7b of the mounting member 7, and the first and second folded portions 9e of the flexible substrate 9. , 9
A concave step 15d serving as a clearance space for f and a mounting hole 15e for mounting the composite operation type electric component to a product (electronic device) are provided.

In the holding member 13, a pair of guided projections 7d of the mounting member 7 are arranged inside the pair of rail portions 14a, and each guided projection 7d is engaged with a different rail portion 14a. By contacting the respective projections 7i of the pair of elastic arms 7c of the mounting member 7 with the upper surface of the pedestal 15, the movable part 1 can be held up and down freely while bending these elastic arms 7c. At this time, as shown in FIGS. 2 and 3, a pair of claw pieces 15b are slidably engaged with the respective notches 7h of the support wall 7a of the mounting member 7, and one of the claw pieces 15b is connected to one of the notches 15b. Said elastic arm 7
The second folded portion 9f of the flexible substrate 9 is arranged between the projection 7i of FIG. When the movable part 1 is assembled to the holding member 13 in this manner, the push button switch 1
A clearance smaller (thinner) than the thickness of the routing portion 12 of the flexible substrate 9 is defined between the first protrusion 1 and the pressing protrusion 15a.

In the composite operation type electric component thus constructed, the sliders 4, 5 are slid on the sliding pattern portion 10 via the slider receiver 3 by rotating the rotary knob 2. Therefore, as described above, the function of the rotary operation type variable resistor capable of changing the resistance output value endlessly according to the rotation angle is obtained. The movable part 1 is held by a holding member 13 so as to be movable up and down, and a rotary knob 2 against the elastic force of the pair of elastic arms 7c.
Is pressed downward by a predetermined stroke, the click spring 11b of the push button switch unit 11 attached to the bottom plate 7b is pressed.
Is lowered toward the pressing protrusion 15a of the pedestal portion 15 and is turned over. The center portion of the click spring 11b is brought into contact with the fixed contact pattern 11a with a click feeling to switch the push button switch portion 11 from off to on. Therefore, a function as a push-operation switch can be obtained.

In the above-described composite operation type electric component, the operation of integrating the bearing member 6 with the mounting member 7 is to snap the snap legs 6a into the locking holes 7g while positioning them with the insertion projections 7e and the positioning projections 6c. Is very simple and the positioning accuracy is high. Also, different portions of the rotary component formed by integrating the rotary knob 2 and the slider receiver 3 are located at different positions on the inner peripheral portion of the bearing member 6, the insertion protrusion 7e of the mounting member 7, and the O-ring 8. Since it is configured to be freely supported, play of the rotating component is easily reduced, and therefore good operability in which the movable component 1 can always be slid smoothly can be expected. Moreover, since grease is applied to the O-ring 8 interposed between the outer peripheral portion of the bearing member 6 and the rotary knob 2, a desired operation resistance can be generated during the rotation operation.

Further, in this composite operation type electric component, not only the sliding pattern portion 10 of the flexible substrate 9 but also the push button switch portion 11 are fixed to the mounting member 7 of the movable component portion 1 so as to be separated from the movable component portion 1. Since it is not necessary to provide a push button switch section on the routing section 12 of the flexible board 9 drawn out, the push button switch section 11 can be easily positioned and fixed to the mounting member 7 before the movable component section 1 is assembled to the holding member 13. In the stage of assembling to the holding member 13, the routing portion 12 does not bind the movable component portion 1, and the assembly workability when the movable component portion 1 and the holding member 13 are combined to complete the composite operation type electric component is greatly improved. I do.

In this composite operation type electric component, a pair of elastic arms 7c is provided at the lower end of the mounting member 7 as a return means for pushing up the movable component 1 when the pressing operation force is removed. The elastic arm 7c of the click spring 1
1b is arranged between the rotary knob 2 and the pedestal portion 15 by utilizing the space around the push button switch portion 11 generated by the height dimension of the component 1b. Thus, a stable return operation can be performed. The return means (elastic arm 7c) is formed as a part of the mounting member 7 and does not incorporate a separate member such as a leaf spring. There is no fear of affecting the transmission of feeling. In addition, since each elastic arm 7c is designed to bend greatly with the protruding portion 7i at the tip as a fulcrum, it is possible to cope with a large operation stroke at the time of pressing operation, and to push the movable component 1 by a required amount. be able to. However, it is also possible to provide a similar elastic arm on the pedestal portion 15 of the holding member 13 to serve as a return means. The first and second folded portions 9e and 9f of the flexible substrate 9 folded in a U-shape are arranged on the concave step 15d of the pedestal 15, and the concave step 15d is placed in the height direction. Therefore, there is no possibility that the elastic force of the folded portions 9e and 9f adversely affect the movable part 1 during the pressing operation.

Further, in this composite operation type electric component, the claw 15b of the holding member 13 is engaged with the notch 7h of the mounting member 7 at the time of non-pressing operation so that the position of the movable component 1 can be regulated. In addition, even if an impact is applied at the time of transportation, the movable part 1 is hardly detached from the holding member 13, so that the handleability is improved. Further, an engagement hole 9 for inserting the pressing protrusion 15a of the pedestal portion 15 into the routing portion 12 of the flexible substrate 9 is provided.
g is provided, and the movement of the routing portion 12 can be restricted by the pressing protrusion 15a. Therefore, there is no problem even if the routing portion 12 is not fixed to the holding member 13, and a complicated fixing operation can be omitted. In addition, since the second folded portion 9f of the flexible substrate 9 is arranged between the one claw piece 15b and the tip end (projection 7i) of the one elastic arm 7c, the drawing portion 12 is provided with the pressing projection 15a. There is no need to worry about undesired rotation around the
Since the clearance between a and the push button switch portion 11 is set to be smaller than the thickness of the routing portion 12, there is no fear that the routing portion 12 comes off the pressing protrusion 15a, and good assembling and handling can be achieved from this point. Sex can be expected. Even if the movable part 1 moves up and down with respect to the holding member 13, the tip of the claw piece 15b is always located within the notch 7h, so that the engagement between the claw piece 15b and the notch 7h is established. Don't worry about coming off. Further, the pressing protrusion 15a and the push button switch 11
May be configured to be always in close contact with each other, but in that case, the operation stroke at the time of the pressing operation becomes small.

Further, in this composite operation type electric component, a pair of guided projections 7d of the mounting member 7 are arranged inside a pair of rail portions 14a whose upper ends are connected, and the guided projections 7d are different from each other. A guide mechanism that guides the movable component 1 up and down by engaging with the rail 14a is configured.
There is no danger that the movable part 1 will fall off from the movable part 1 and smooth sliding movement of the movable part 1 is guaranteed. If a guide mechanism for moving the movable part 1 up and down smoothly is provided on the back side of the mounting member 7, the guide mechanism is not required on the front side of the rotary knob 2. It is possible to cope with a case where a large space cannot be secured between the housing of the electronic device) and the front surface of the rotary knob 2, and it is easy to achieve a desired thickness reduction.

In the above-described embodiment, the description has been given of the one having the function of the rotary operation type variable resistor. However, the one having the function of the rotary operation type encoder may be used.
The push button switch is not limited to the fixed contact pattern 11a and the movable contact including the click spring 11b, but is configured such that the movable contact is printed and formed on a flexible substrate and opposed to the fixed contact pattern via a spacer. May be. In this case, the click spring can be omitted.

If the projections are provided and these guided projections are engaged with different rail portions, there is no danger that the guided projections will fall off the rail portions, and the movable component portion can be slid more smoothly. Can be.

If an O-ring coated with grease is interposed between the outer peripheral portion of the bearing member and the rotary knob, not only the inner peripheral portion but also the outer peripheral portion of the rotating component are rotatably supported. Therefore, the inclination of the rotary knob can be more reliably prevented, and the grease applied to the O-ring can generate a desired operation resistance during the rotation operation. Inconvenience such as rotation on the contrary can be less likely to occur.

A notch is provided in the support wall of the mounting member, and a claw is provided on the holding member to engage with the notch when the rotary knob is not pressed so as to regulate the position of the movable part. In this case, even if an impact is applied during transportation or the like, the movable part is unlikely to come off from the holding member, so that handleability is improved.

Further, as a movable contact of the push button switch section,
If a dome-shaped tact spring that generates a click feeling at the time of inversion is used, there is no deviation between the timing at which the push button switch section is turned on and the timing at which the click feeling is felt. Furthermore, if the tact spring is covered with an insulating adhesive sheet and fixed to a flexible substrate, the adhesive sheet can serve as a cushion even with a metal tact spring, and a pressing member such as a pressing protrusion (push button switch) can be used. (Operation means of the section) abuts against the push-button switch section, thereby making it possible to reduce the contact sound.
