The composite operation type input device listed here is a rotation operation input in a predetermined circumferential direction of the dial 100 (first operation body), a tilt operation input in a surrounding four directions from a predetermined state of the dial 100, and a push button 400 This is an input device capable of inputting a pressing operation from an initial state to be described later. This input device includes a dial 100, a key top 200, a feeler 300, a press button 400, a substrate 500 (fixing member), a reinforcing plate 600, a rotation detection means 700, a tilt detection means 800, and a press. Movement detection means 900. Hereinafter, the operation of each unit will be described.

  As shown in FIGS. 1, 3, 4, and 5, the dial 100 is a ring-shaped resin molded product that can be rotated in a predetermined circumferential direction and can be tilted in an arbitrary direction around the predetermined state. . The dial 100 has a top plate portion 110, a shaft portion 120, an outer wall portion 130, and a fixed plate 140. The top plate portion 110 is a substantially trapezoidal portion in cross-sectional view, and a circular hole 111 is formed at the center thereof. A cylindrical shaft 120 is erected on the peripheral edge of the hole 111 on the lower surface of the top plate 110. The shaft portion 120 communicates with the hole portion 111 and has a hole portion 121 having an outer diameter larger than that of the hole portion 111. A fixing plate 140, which is a ring-shaped metal plate, is attached to the lower end portion of the shaft portion 120 by heat caulking or the like. The inner diameter of the fixing plate 140 is substantially the same as the inner diameter of the hole 121 of the shaft portion 120, and the outer diameter of the fixing plate 140 is larger than the outer diameter of the shaft portion 120. For this reason, the outer peripheral edge portion of the fixing plate 140 protrudes outward from the shaft portion 120. The fixing plate 140 corresponds to a flange in the claims. A cylindrical outer wall portion 130 that is shorter than the shaft portion 120 is erected on the outer peripheral edge portion of the lower surface of the top plate portion 110. A ring-shaped accommodation space for accommodating the feeler 300 and the upper portion 211 of the bearing portion 210 of the key top 200 is defined between the shaft portion 120 on the lower surface of the top plate portion 110 and the outer wall portion 130. .

  As shown in FIGS. 2 and 5, the feeler 300 is a leaf spring in which a metal plate is press-molded. The feeler 300 includes a substantially L-shaped attachment portion 310 facing downward in a sectional view, and a pair of spring portions 320 provided at both ends of the lower end portion of the attachment portion 310. The attachment portion 310 is attached between the shaft portion 120 on the lower surface of the top plate portion 110 and the outer wall portion 130 (that is, the ceiling surface of the housing space) by heat caulking or the like as shown in FIG. Both spring portions 320 are plate members extending in an arc shape along the accommodation space, and the tip portions thereof are bent in an arc shape so as to approach each other. The dimension between the apexes of the tip of the spring part 320 is smaller than the outer diameter of the convex part of the convex / concave surface 211b described later of the key top 200. That is, the top of the tip of the spring part 320 is elastically in contact with the uneven surface 211b of the key top 200 as shown in FIG. When the dial 100 is rotated, the spring portion 320 is amplitude-moved on the uneven surface 211 b of the key top 200, thereby giving an operational feeling to the rotation operation of the dial 100.

  As shown in FIGS. 1 to 6, the key top 200 is a molded product made of resin. The key top 200 has a bearing portion 210, four leg portions 220, four arms 230, and four pressing portions 240. As shown in FIGS. 3 and 4, the bearing portion 210 is a cylindrical body having a substantially convex cross section installed on the substrate 500, and has a rigidity that does not elastically deform due to the rotation and tilting of the dial 100. ing. Regarding the rigidity, the material and thickness dimension of the bearing portion 210 may be appropriately selected and set so that the bearing portion 210 does not elastically deform in consideration of the load applied to the bearing portion 210 when the dial 100 rotates and tilts. In the present embodiment, the bearing portion 210 has a thickness that does not cause elastic deformation due to a load when the dial 100 rotates and tilts. The bearing portion 210 has an upper step portion 211 and a lower step portion 212. The upper stage 211 is provided with a small diameter hole 211a, and the lower stage 212 is provided with a large diameter hole 212a communicating with the small diameter hole 211a. A shaft portion 120 (described later) of the dial 100 is fitted in the small diameter hole 211a of the upper step portion 211. A slidable contact surface 211a1, which is a vertical surface, is provided at the lower end portion of the inner peripheral surface of the small diameter hole 211a. The diameter of the sliding contact surface 211 a 1 is slightly larger than the outer diameter of the shaft portion 120 of the dial 100. When the dial 100 is in a predetermined state, which will be described later, the sliding contact surface 211a1 is disposed to face the shaft portion 120 of the dial 100 substantially in parallel with a slight gap so that the shaft portion 120 can be freely rotated. I support. In this way, the bearing portion 210 pivotally supports the dial 100 so as to be rotatable in the circumferential direction. In addition, a tapered surface 211a2 is provided on the inner peripheral surface of the small diameter hole 211 above the sliding contact surface 211a1 so that the cross-sectional shape of the upper step portion 211 gradually decreases toward the upper side (that is, the dial 100 side). . The taper surface 211a2 avoids interference between the shaft portion 120 and the upper step portion 211 of the bearing portion 210 when the dial 100 is tilted from the predetermined state to the surrounding arbitrary direction. Further, the outer peripheral surface of the upper step portion 211 of the bearing portion 210 is provided with an uneven surface 211b.

  On the other hand, the bottom surface of the large-diameter hole 212a of the lower step portion 212 (that is, the peripheral portion on the lower side of the small-diameter hole 211a) is a step portion 212a1. The diameter of the large-diameter hole 212a is larger than the outer diameter of a fixing plate 140 described later of the dial 100. The fixing plate 140 of the dial 100 is accommodated in the large-diameter hole 212a, and the outer peripheral edge portion of the fixing plate 140 is in contact with the step portion 212a1. As shown in FIG. 7, when the dial 100 is tilted from a predetermined state, a portion of the dial 100 opposite to the tilting direction of the fixing plate 140 comes into contact with a portion of the stepped portion 212 a 1 opposite to the tilting direction. It functions as a fulcrum for tilting. Further, as shown in FIG. 6, substantially L-shaped leg portions 220 are arranged on the outer peripheral surface of the lower step portion 212 with a space therebetween.

  As shown in FIGS. 1 and 6, each leg portion 220 includes a beam portion 221 and a mounting portion 222. The beam portion 221 is a plate body that extends substantially horizontally from the outer peripheral surface of the lower step portion 212 of the bearing portion 210. The attachment portion 222 is a substantially cylindrical body that is suspended from the distal end portion of the beam portion 221. The attachment portion 222 passes through the holes of the substrate 500 and the reinforcing plate 600 and is attached to the reinforcing plate 600 by heat caulking or the like. As a result, the key top 200 is fixed onto the substrate 500 via the reinforcing plate 600. The substrate 500 is a known circular flexible printed circuit board. The reinforcing plate 600 is a circular metal plate. The reinforcing plate 600 is attached to the lower surface of the substrate 500 to reinforce the substrate 500.

  As shown in FIGS. 2 and 6, each arm 230 is an arc-shaped plate body that is elastically deformable and is suspended between the distal ends of the beam portions 221 of the leg portions 220. Each pressing portion 240 is a protrusion protruding from the upper and lower surfaces of the arm 230. The pressing portion 240 is disposed on the lower side of the outer wall portion 130 described later of the dial 100 and at a position corresponding to four tilting operation input directions of the dial 100, and supports the outer wall portion 130 from below. That is, the pressing portion 240 supports the outer wall portion 130 of the dial 100 from below in the tilting operation input direction of the dial 100, and the step portion 212a1 of the bearing portion 210 abuts on the fixing plate 140 of the dial 100 from above. The shaft portion 120 of the dial 100 is maintained in a state substantially parallel to the sliding contact surface 211a1 of the bearing portion 210 of the key top 200. As described above, when the dial 100 tilts with a part of the fixed plate 140 as a fulcrum, the pressing portion 240 on the tilting direction side is pressed by the outer wall portion 130 of the dial 100, and the arm 230 corresponding to the pressing portion 240 is elastically deformed. It is like that.

  As shown in FIGS. 3 to 5, the push button 400 includes a button body 410 and a rotation stopper 420. The button body 410 is a substantially circular cup body made of resin. The outer diameter of the button body 410 is slightly smaller than the diameter of the hole 111 of the top plate 110 of the dial 100. That is, the button body 410 is accommodated in the hole 111 of the dial 100 so as to be movable up and down. At the lower end portion of the button body 410, a ring-shaped retaining portion 411 that protrudes outward is provided. The outer diameter of the retaining portion 411 is larger than the diameter of the hole portion 111 of the dial 100 and smaller than the hole portion 121 of the shaft portion 120 of the dial 100. That is, the retaining portion 411 is accommodated in the hole portion 121 of the dial 100 so as to be movable up and down, and can come into contact with the bottom surface of the hole portion 121 (that is, the lower peripheral edge portion of the hole portion 111). Since the retaining portion 411 forms the bottom surface of the hole portion 121, the button body 410 is prevented from coming off upward. Further, the retaining portion 411 is provided with substantially rectangular cutout portions 411a at a pitch interval of 180 °. Further, a cross-shaped convex portion 412 is provided on the bottom surface of the hole portion of the button body 410 as shown in FIGS.

The rotation stopper 420 is a resin molded product. The rotation stopper 420 includes a base 421, a pair of legs 422, an auxiliary leg 423, a support 424, and a pair of suspension parts 425. The base portion 421 is a ring-shaped plate-like body whose outer diameter is substantially the same as that of the retaining portion 411. On the lower surface of the base portion 421, cylindrical leg portions 422 are projected at a pitch interval of 180 °. A columnar auxiliary leg 423 is provided in the vicinity of one leg 422 on the lower surface of the base 421. The leg part 422 and the auxiliary leg part 423 penetrate the attachment holes of the substrate 500 and the reinforcing plate 600 so as to be movable up and down. The support portion 424 is a cylindrical body having an outer diameter smaller than the inner diameter of the hole portion of the button main body 410. The support portion 424 is accommodated in the hole of the button main body 410 and abuts against the cross-shaped convex portion 412 of the button main body 410. When the button main body 410 is pressed and moved from the initial state , the cross-shaped convex portion 412 presses the support portion 424 and pushes the rotation stop portion 420 downward. In addition, a columnar protrusion 424 a protrudes from the center of the lower surface of the support portion 424. This protrusion 424a is a part that presses down the pressing movement detecting means 900 in accordance with the pressing movement of the rotation stopper 420. A suspension portion 425 is suspended between the base portion 421 and the support portion 424. The suspension part 425 is arranged 180 ° away from the leg part 422. The suspension part 425 is inserted into the notch part 411a of the button main body 410 to prevent the button main body 410 from rotating in the circumferential direction.

  As shown in FIGS. 3 to 5, the pressing movement detecting unit 900 includes a pressing switch 910 that is pressed by the protrusion 424 a of the pressing button 400 and a fixing tape 920. The push switch 910 has a movable contact 911 and fixed contacts 912a and 912b. The fixed contact 912 a is a circular conductor provided at the center on the substrate 500. The fixed contact 912 b is an elliptical conductor provided around the fixed contact 912 a on the substrate 500. The movable contact 911 is a metal plate having a circular arc cross section. The movable contact 911 has an outer peripheral edge portion disposed on the fixed contact 912b and a top portion disposed on the fixed contact 912a. The fixed tape 920 is put on the movable contact 911 and fixed on the substrate 500. On the top of the fixing tape 920, the protrusion 424a of the push button 400 is placed. That is, the movable contact 911 supports the push button 400 via the fixed tape 920, thereby holding the push button 400 in the initial state. In other words, the state where the push button 400 is supported by the movable contact 911 is the initial state of the push button 400. When the push button 400 moves down, the tops of the fixed tape 920 and the movable contact 911 are pushed down by the protrusions 424a and come into contact with the fixed contact 912a. As a result, the fixed contacts 912a and 912b are brought into conduction, and a signal indicating the pressing movement of the pressing button 400 is output.

  As shown in FIGS. 3 to 5, the rotation detecting unit 700 includes a brush 710 and a plurality of types of fixed contacts 720. The fixed contacts 720 are annularly arranged around the fixed contacts 912b on the substrate 500 with a space therebetween. The brush 710 has a fixed portion 711 and four contact arms 712. The fixing portion 711 is a ring-shaped plate body whose inner diameter is substantially the same as the inner diameter of the fixing plate 140 and whose outer diameter is smaller than the outer diameter of the fixing plate 140. The fixing portion 711 is attached to the lower end portion of the shaft portion 120 of the dial 100 together with the fixing plate 140 by heat caulking or the like. The contact arm 712 is formed by cutting down a part of the outer peripheral edge of the fixed portion 711. When the tip of the contact arm 712 slides on the substrate 500 and selectively contacts the fixed contact 720, a signal indicating the rotation angle of the dial 100 is output.

  As shown in FIGS. 3 to 5, the tilt detection means 800 includes four peripheral switches 810 that are pressed by the pressing portion 240 of the key top 200 in response to four tilting operation inputs of the dial 100, and a ring-shaped fixing. And a tape 820. Each peripheral switch 810 has a movable contact 811 and fixed contacts 812a and 812b. The fixed contacts 812a are circular conductors arranged around the fixed contacts 720 on the substrate 500 at the same pitch as the pressing portions 240 of the key top 200. The fixed contacts 812b are elliptical conductors provided around the fixed contacts 812a on the substrate 500, respectively. The movable contact 811 is a metal plate having a circular arc cross section. The movable contact 811 has an outer peripheral edge portion disposed on the fixed contact 812b and a top portion disposed on the fixed contact 812a. The fixed tape 820 is placed on the movable contact 811 and fixed on the substrate 500. A pressing portion 240 is placed on the movable contact 811 of the fixed tape 820. The four movable contacts 811 respectively support the four pressing portions 240 via the fixed tape 820, thereby supporting the dial 100 supported by the pressing portions 240 in a state substantially parallel to the substrate 500. This state is the predetermined state of the dial 100 described above. When the dial 100 is tilted in any one of four directions from the predetermined state, the tops of the fixed tape 820 and the movable contact 811 are pressed by the pressing portion 240 and come into contact with the fixed contact 812a. Thereby, the fixed contacts 812a and 812b are brought into conduction, and a signal indicating tilting in any one of the four directions of the dial 100 is output.

  Hereinafter, the assembly procedure of the composite operation type input device having the above-described configuration will be described in detail. First, a substrate 500 and a reinforcing plate 600 on which fixed contacts 720, 812a, 812b, 912a, and 912b are printed are prepared. Then, the reinforcing plate 600 is fixed to the substrate 500. Thereafter, the outer peripheral edge portions of the movable contacts 811 are respectively installed on the fixed contacts 812b, and all the movable contacts 811 are fixed on the substrate 500 with the fixed tape 820. Similarly, a movable contact 911 is installed on the fixed contact 912b, and the movable contact 911 is fixed on the substrate 500 with a fixed tape 920.

  Thereafter, the feeler 300 is inserted into the accommodation space of the dial 100, and the attachment portion 310 of the feeler 300 is attached to the ceiling surface of the accommodation space by heat caulking or the like. Thereafter, the shaft portion 120 of the dial 100 is inserted into the small diameter hole 211a of the upper step portion 211 of the bearing portion 210 of the key top 200 from above with the pair of spring portions 320 of the feeler 300 being elastically deformed away from each other. At the same time, the upper stage portion 211 of the bearing portion 210 is inserted into the accommodation space of the dial 100. Thereafter, when the spring portion 320 is released, the spring portion 320 is restored and disposed on the uneven surface 211b of the upper step portion 211. Thereafter, the fixing plate 140 and the fixing portion 711 of the brush 710 of the rotation detecting means 700 are attached to the lower stage portion of the shaft portion 120 of the dial 100 by heat caulking or the like. As a result, the outer peripheral edge portion of the fixing plate 140 contacts the stepped portion 212 a 1 of the key top 200. In this state, the slidable contact surface 211 a 1 of the small diameter hole 211 a of the upper stage portion 211 of the bearing portion 210 is disposed so as to face the shaft portion 120 of the dial 100 substantially in parallel with a slight gap. In this way, the dial 100 and the key top 200 are unitized. Hereinafter, this is referred to as a unit.

  Meanwhile, the leg portion 422 and the auxiliary leg portion 423 of the rotation stop portion 420 of the push button 400 are inserted into the holes of the substrate 500 and the reinforcing plate 600, respectively. At this time, the protrusions 424 a of the rotation stopper 420 are installed on the tops of the fixed tape 920 and the movable contact 911. Thereafter, the button body 410 of the push button 400 is put on the support portion 424 of the rotation stop portion 420. As a result, the cross-shaped convex portion 412 of the button body 410 is placed on the support portion 424 of the rotation stopping portion 420.

  Thereafter, the attachment portions 222 of the leg portions 220 of the key top 200 of the unit are inserted into the attachment holes of the substrate 500 and the reinforcing plate 600, respectively, and the lower step portion 212 of the bearing portion 210 of the key top 200 is installed on the substrate 500. At this time, the button body 410 and the rotation stopper 420 of the push button 400 on the substrate 500 are inserted into the hole 121 of the shaft 120 of the dial 100 and the hole 111 of the top plate 110 of the unit 100. Specifically, the upper end portion of the button body 410 is accommodated in the hole 111 of the top plate portion 110, and the retaining portion 411 of the button body 410, the support portion 424 of the rotation stopping portion 420, and the suspension portion 425 are the shaft portion 120. Is accommodated in the hole 121. At the same time, the pressing portions 240 of the key tops 200 are respectively installed on the movable contacts 811 of the fixed tape 820 of the tilt detecting means 800, and the tips of the contact arms 712 of the brush 710 come into contact with the substrate 500. Thereafter, the attachment portion 222 of the key top 200 is attached to the reinforcing plate 600 by heat caulking or the like.

  Hereinafter, the usage method of the composite operation type input device assembled as described above and the operation of each unit will be described. When the dial 100 is rotated in the circumferential direction, the shaft portion 120 of the dial 100 rotates while being in sliding contact with the sliding contact surface 211 a 1 of the bearing portion 210 of the key top 200. For this reason, the dial 100 rotates in the circumferential direction around the shaft portion 120 with almost no backlash. At this time, according to the rotation of the dial 100, the pair of spring portions 320 of the feeler 300 moves in amplitude on the uneven surface 211 b of the bearing portion 210 of the key top 200, thereby giving an operational feeling to the rotation operation of the dial 100. At the same time, the contact arm 712 of the brush 710 attached to the lower end portion of the shaft portion 120 of the dial 100 slides on the substrate 500 and selectively contacts the fixed contact 720 on the substrate 500. Thereby, a signal corresponding to the rotation angle of the dial 100 is output.

  When the dial 100 is tilted in one of the four directions from the predetermined state, a portion of the dial 100 opposite to the tilting direction of the fixing plate 140 is a bearing of the key top 200 as shown in FIG. The step part 212 a 1 of the part 210 abuts on the part of the step part 212 a 1 opposite to the tilting direction and functions as the tilting fulcrum of the dial 100, and the shaft part 120 of the dial 100 tilts with respect to the bearing part 210 of the key top 200. At this time, since the tapered surface 211a2 is provided above the sliding contact surface 211a1 of the small diameter hole 211a of the upper step portion 211 of the bearing portion 210, interference between the shaft portion 120 and the upper step portion 211 of the bearing portion 210 is avoided. . At the same time, the portion on the tilting direction side of the outer wall portion 130 of the dial 100 presses the pressing portion 240 of the key top 200 located on the tilting direction side, and elastically deforms the arm 230 provided with the pressing portion 240. . Then, the pressing unit 240 presses the peripheral switch 810 located on the tilt direction side. As a result, the movable contact 811 of the peripheral switch 810 is elastically deformed, and the top of the movable contact 811 contacts the fixed contact 812a. As a result, a signal indicating the tilting of the dial 100 in the tilting direction is output. Thereafter, when the dial 100 is released, the movable contact 811 and the arm 230 are restored, and the pressing portion 240 on the tilt direction side and the portion on the tilt direction side of the outer wall portion 130 of the dial 100 are pushed up. Thereby, the dial 100 returns to the predetermined state.

  Even when the dial 100 is tilted in one of the four directions perpendicular to the tilting direction from the predetermined state, as shown in FIG. 7B, each part operates similarly to the tilting direction. . Therefore, detailed description is omitted.

  When the button main body 410 of the push button 400 is pressed downward from the initial state, the cross-shaped convex portion 412 of the button main body 410 pushes down the support portion 424 of the rotation stop portion 420. Thereby, the protrusion 424a of the support portion 424 presses the movable contact 911 of the pressing movement detecting means 900. As a result, the movable contact 911 is elastically deformed, and the top of the movable contact 911 comes into contact with the fixed contact 912a. As a result, a signal indicating the pressing movement of the pressing button 400 is output. Thereafter, when the push button 400 is released, the movable contact 911 is restored, and the rotation stopper 420 and the button body 410 are pushed up. As a result, the push button 400 returns to the initial state.

  In the case of such a composite operation type input device, the lower end portion of the inner peripheral surface of the small diameter hole 211a of the upper step portion 211 of the bearing portion 210 is substantially parallel to the outer peripheral surface of the shaft portion 120 of the dial 100 in a predetermined state. A slidable contact surface 211a1 having a diameter slightly larger than the outer diameter of the shaft portion 120 is formed. Therefore, when the dial 100 is rotated, the shaft portion 120 of the dial 100 is in sliding contact with the sliding contact surface 211a1 of the bearing portion 210, so that rattling when the dial 100 is rotated can be suppressed. Further, even when external vibration or the like is applied to the dial 100, rattling of the dial 100 can be suppressed by the shaft portion 120 of the dial 100 coming into contact with the sliding contact surface 211a1. Moreover, since the bearing part 210 has the rigidity which does not elastically deform by rotation and tilting of the dial 100, the above-mentioned rattling of the dial 100 can be suitably suppressed. Further, the outer peripheral edge portion of the fixing plate 140 of the shaft portion 120 of the dial 100 is supported from above by the step portion 212 a 1 of the bearing portion 210 of the key top 200, while the outer wall portion 130 of the dial 100 is the pressing portion 240 of the key top 200. Are supported from below. Also with this configuration, it is possible to suppress rattling of the dial 100 due to rattling during rotation of the dial 100 and vibrations from the outside.

  Further, when the dial 100 is tilted, the portion of the dial 100 opposite to the tilting operation direction of the fixing plate 140 contacts the portion of the stepped portion 212a1 of the bearing portion 210 opposite to the tilting operation direction, and the dial 100 tilts. It is designed to function with the fulcrum of For this reason, the tilting stroke of the dial 100 can be stabilized. Moreover, since the upper surface portion of the sliding contact surface 211a1 of the small diameter hole 211a of the upper step portion 211 of the bearing portion 210 is provided with a tapered surface 211a2 in which the cross-sectional shape of the upper step portion 211 gradually decreases upward, the dial 100 Interference between the shaft portion 120 of the dial 100 and the upper step portion 211 of the bearing portion 210 can be avoided during the tilting operation. Moreover, since the uneven surface 211b is formed in the outer peripheral surface of the upper step part 211 of the bearing part 210 of the key top 200, the uneven thickness of the dial 100 caused by providing the uneven surface on the dial 100 side can be prevented. The shape of the dial 100 can be simplified. Therefore, it is possible to prevent the occurrence of sink marks or the like due to uneven thickness in the dial 100 that forms the appearance of the composite operation type input device. In addition, since the leg portion 220, the arm 230, and the pressing portion 240 are provided around the lower step portion 212 of the bearing portion 210, the leg portion 220, the arm 230, and the pressing portion 240, the uneven surface 211b, and the feeler 300 are provided.
