The elastic arm 14 is formed to have an outer shape of the same size as the outer shape of the lid body 13, and the initial position (center of the operating body 10) with respect to the sliding operation direction of the operating body 10. A ring-shaped elastic diaphragm portion 14a having a zigzag cross section for generating a restoring force to the position). A central hole 14b having a size covering the outer periphery of the concave portion 11c of the central pressing member 11 is formed in the central portion of the elastic diaphragm portion 14a, and the bottom surface is inserted into the insertion hole 13b of the lid 13 on the lower surface. Four protrusions 14c are formed that press and hold the held portion 4a of the movable electrode 4 against the holding surface 2f of the holding portion 2e and the peripheral common electrode 5. In addition, the elastic arm 14 is not formed with a hole in which moisture or dust may enter the inside of the housing 2 from the outside except for the central hole 14b, and an opening formed in the housing 2 It is formed in a lid shape that covers and covers.

  The restraining member 15 is formed in an annular plate shape that covers the outer upper surface of the elastic diaphragm portion 14 a of the elastic arm 14, and engages with the claw portions 2 i formed on the outer surface of each side of the housing 2 4. Each arm portion 15a projects downward, and a central hole 15b is formed by raising the inner peripheral portion in a cylindrical shape so as not to disturb the movement of the elastic diaphragm portion 14a. The restraining member 15 is assembled by engaging each arm portion 15a with each claw portion 2i from above so as to restrain the lid 13 and the elastic arm 14.

  Next, the operation of the multidirectional input device 1 of the first embodiment will be described.

  When the operating body 10 of the operating member 9 of the multidirectional input device 1 is slid and moved to the outside in an arbitrary radial direction, the peripheral pressing member 12 becomes a guide of the housing 2 as shown in FIG. While moving with the upper surface 2j of the wall 2b and the lower portion 13c of the central hole 13a of the lid 13, the peripheral pressing portion 12a of the peripheral pressing member 12 contacts the peripheral movable electrode 4 while moving in the sliding direction. Touch. When the operating body 10 is further slid, the peripheral pressing portion 12a deforms the peripheral movable electrode 4, and the peripheral movable electrode 4 and the peripheral fixed contact 3 below the contact are brought into conduction. As a result, the multidirectional input device 1 can detect that the operation body 10 has been input to the outside in an arbitrary radial direction.

  This input operation to the outside in the radial direction causes the peripheral movable electrode 4 to be deformed in the thickness direction, thereby generating a high repulsive force on the peripheral movable electrode 4. Here, since the peripheral movable electrode 4 of the multi-directional input device 1 of the first embodiment includes the reaction force adjusting portions 4c and 4d, which part of the peripheral movable electrode 4 has the reaction force in the circumferential direction. In this case, the variation in the operating force on the radially outer side can be reduced. The reaction force adjusting portions 4c and 4d are formed so that the width dimension of the vicinity 4e of the held portion 4a is smaller than the width dimension of the portion 4f other than the vicinity of the held portion 4a. In 4e, the reaction force can be reduced, and in the portion 4f other than the vicinity of the held portion 4a, the reaction force can be increased. As a result, it is possible to reduce variation in the operating force toward the radially outer side, so that the operation feeling of the multidirectional input device 1 is improved.

  As described above, in the reaction force adjusting portions 4c and 4d, as shown in FIGS. 4 and 5, the thickness of the vicinity 4e of the held portion 4a is smaller than the thickness of the portion 4f other than the vicinity of the held portion 4a. As shown in FIG. 6 and FIG. 7, the peripheral movable electrode 4 is formed in a concave or convex shape along the circumference of the portion 4 f other than the vicinity of the held portion 4 a. Thus, as in the case of changing the width dimension, the reaction force is reduced in the vicinity 4e of the held portion 4a, and the reaction force is increased in the portion 4f other than the vicinity of the held portion 4a. It is also possible.

  Further, since the peripheral movable electrode 4 has a supported portion 4b supported without any restriction on the support portion 2g of the housing 2, a reaction force generated in the vicinity of the supported portion 4b is generated. The peripheral movable electrode 4 can be stably supported without being raised so much. Further, by forming the supported portion 4b integrally with the reaction force adjusting portion 4d, it is possible to reduce the process of forming the reaction force adjusting portion 4d, and to reduce the manufacturing cost of the peripheral movable electrode 4. It has become.

  Furthermore, the holding portions 2e of the housing 2 that holds the held portion 4a of the movable electrode 4 for the periphery are formed at the four corners of the housing 2 as shown in FIG. As a result, the outer corner of the housing 2 can be suitably used without enlarging the outer shape of the housing 2, and the corners of the housing 2 that are likely to become a dead space in the housing 2 can be suitably used. Can be achieved. Further, since the peripheral common electrode 5 is formed on the holding surface 2f of the holding portion 2e so as to be electrically connected to the peripheral movable electrode 4, only the peripheral common electrode 5 is brought into contact with the peripheral movable electrode 4. It is possible to integrally form the space provided in the holding portion 2e and the holding portion 2e, and it is possible to further reduce the size of the multidirectional input device 1.

  The multidirectional input device 1 according to the first embodiment includes a central movable electrode 7 in contact with the central fixed contact 6 and the central common electrode 8 with respect to the pressing direction PD of the operation member 9. Accordingly, by pressing the operating body 10 of the operating member 9, the central pressing portion 11d of the central pressing member 11 deforms while pressing the central movable electrode 7, and the central movable electrode 7 and the central fixed contact are deformed. 6 makes it possible to detect an input operation in the pressing direction PD. At that time, the peripheral pressing member 12 disposed on the operating member 9 is restricted from moving forward in the pressing direction PD by the upper surface 2j of the guide wall 2b. Since 11a is loosely fitted in the central hole 12b of the peripheral pressing member 12, it can move forward (downward in the drawing) in the pressing direction PD while sliding through the central hole 12b. Thereby, even if the upper surface 2j of the guide wall 2b and the peripheral pressing member 12 are in contact, the operation member 9 can be moved in the pressing direction. Therefore, not only the input operation to the outside in the radial direction but also the input operation to the pressing direction PD is possible.

  In this input operation in the pressing direction PD, since the central movable electrode 7 is formed in a dome shape, a reaction force is generated in a direction opposite to the pressing direction PD, and erroneous input can be prevented. Yes. In addition, it is possible to obtain a good click feeling when an intentional operation is performed in the pressing direction PD.

  When the input operation in the circumferential direction and the push-down direction PD is completed, it is necessary to return the operation body 10 of the operation member 9 to the initial position where the operation member 10 is disposed in order to facilitate the next input operation. At this time, since the multidirectional input device 1 includes the elastic arm 14 that generates a restoring force for restoring the operation member 9 to the initial position, the initial position is automatically set when performing an input operation. It becomes possible to perform input operation from. Further, since the elastic arm 14 is formed in a lid shape that seals the inside of the housing 2, it is possible to prevent intrusion of malfunction factors such as dust and moisture into the housing 2.

  In addition, the fixed contact 3 for the periphery, the common electrode 5 for the periphery, the fixed contact 6 for the center, and the center that are disposed inside the housing 2 and need to be electrically connected to members outside the housing 2. Since all the common electrodes 8 are formed by insert molding, the number of parts of the multidirectional input device 1 can be reduced and the assembly process can be reduced. In addition, since the leading end portions 3b, 5b, 6b, 8b of each of the lead terminals 3a, 5a, 6a, 8a are formed to have different shapes, it is less likely to cause erroneous assembly during assembly. The yield of the multidirectional input device 1 can be improved.

  That is, the multi-directional input device 1 of the first embodiment makes it possible to obtain a comfortable operation feeling in the input operation in the radially outer direction and the pressing direction PD, while reducing cost, reliability, and the like. Yield can be improved.

(2) Second Embodiment In the multidirectional input device 1a of the second embodiment, as shown in FIG. 13, the guide wall 2b of the housing 2, the peripheral movable electrode 4, the central movable electrode 7 and The same members as those used in the multidirectional input device 1 of the first embodiment are used for the members disposed in the multidirectional input device 1a other than the central common electrode 8. Here, as shown in FIG. 13, the peripheral movable electrode 4 and the central movable electrode 7 used in the second embodiment are communicated via a support portion 4g and formed integrally. As a result, in the second embodiment, the central common electrode 8 is eliminated without being disposed. In addition, a slit 2k is provided in a part of the annular guide wall 2b to allow the support 4g to connect and support the peripheral movable electrode 4 and the central movable electrode 7 to pass therethrough.

  Next, the operation of the multidirectional input device 1a of the second embodiment will be described.

  Similar to the multidirectional input device 1 of the first embodiment, the multidirectional input device 1a of the second embodiment can perform an input operation in the radially outward direction and the pressing direction PD. However, in the multi-directional input device 1a of the second embodiment, the peripheral movable electrode 4 and the central movable electrode 7 are integrally formed, so that the peripheral movable electrode 4 and the central movable electrode 7 are interposed. The contact between the center fixed contact 6 and the center movable electrode 7 can be detected by making the center fixed contact 6 and the peripheral common electrode 5 conductive. Thereby, it is not necessary to arrange the central common electrode 8, and the number of components can be reduced as compared with the components of the multidirectional input device 1 of the first embodiment. Assembling of the multidirectional input device 1a can be prevented. Further, it is possible to reduce the cost of the multidirectional input device 1a.

(3) Third Embodiment As shown in FIG. 14, the multidirectional input device 1b of the third embodiment gives two-stage input to the input operation in the circumferential direction. The multi-directional input device 1 is formed by applying the following members. That is, as shown in FIG. 14, the multidirectional input device 1 b of the third embodiment is similar to the first embodiment in the casing 2, the peripheral fixed contact 3, the peripheral movable electrode 4, and the peripheral common. Each member used for input to the outside in the radial direction such as the electrode 5, each member used for input in the pressing direction at the center, such as the central fixed contact 6 and the central movable electrode 7, and the central common electrode 8, and the operation member 9, a lid 13, an elastic arm 14, and a restraining member 15, and a second peripheral movable electrode 16 in the vicinity of the peripheral fixed contact 3 in order to perform a two-stage input operation radially outward. And a second peripheral common electrode 17. Specifically, the second peripheral movable electrode 16 and the second peripheral common electrode 17 are formed as follows. In addition, the specific description is abbreviate | omitted about the thing using the member similar to the multi-directional input device 1 of 1st Embodiment.

  As shown in FIG. 15, the second peripheral common electrode 17 is formed integrally with the housing 2 by insert molding, and the portion exposed from the bottom surface 2c outside the guide wall of the housing 2 is in four directions. It is formed in a substantially U-shape covering each peripheral fixed contact 3 while being insulated by each peripheral fixed contact 3. The second peripheral common electrode 17 has other lead terminals 17 a that are drawn out of the housing 2 in the same manner as other contacts or electrodes 3, 5, 6, 8 inserted in the housing 2. The leading end portion 17b of the lead terminal has a special shape that can be distinguished from the other lead terminals 3a, 5a, 6a, and 8a.

  As shown in FIGS. 14 to 16, the second peripheral movable electrode 16 is formed on an elliptical dome-shaped curved portion 16a protruding in the thickness direction of the peripheral movable electrode 4, and on the peripheral edge of the curved portion 16a. It has a pedestal portion 16b in contact with the second peripheral common electrode 17 and is insulated from the peripheral fixed contact 3 and the peripheral movable electrode 4 in an initial state (a state where no input operation is performed radially outward). However, they are arranged so as to cover the peripheral contact points 3 in the four directions. Further, the pedestal portion 16 b of the second peripheral movable electrode 16 is disposed so as to be in contact with the second peripheral common electrode 17.

  Next, the operation of the multidirectional input device 1b of the third embodiment will be described.

  The multidirectional input device 1b of the third embodiment enables two-stage input to the outside in the radial direction in addition to the input performed by the multidirectional input device 1 of the first embodiment. For example, when the operating body 10 of the operating member 9 shown in FIG. 14 is slid to the outside in an arbitrary radial direction, the peripheral pressing member 12 presses and deforms the peripheral movable electrode 4. Then, the peripheral movable electrode 4 comes into contact with any one of the second peripheral movable electrodes 16 arranged in four directions, and the second peripheral common electrode 17 and the peripheral contact with the second peripheral movable electrode 16 The common electrode 5 is electrically connected. Thereby, the multidirectional input device 1b can appropriately detect an input operation to an arbitrary outer side in the radial direction. This is the input operation in the first step in the circumferential direction.

  Then, in a state where the peripheral movable electrode 4 is in contact with the second peripheral movable electrode 16, when the operating body 10 of the operating member 9 is further slid outward in the arbitrary radial direction, the peripheral pressing member 12 is The second movable electrode for peripheral edge 16 in contact with the movable electrode for peripheral 4 and the movable electrode for peripheral edge 4 is further pressed. Then, the pressed second peripheral movable electrode 16 comes into contact with the peripheral fixed contact 3 disposed below. Accordingly, the peripheral common electrode 5 connected to the peripheral movable electrode 4 is electrically connected to the second peripheral common electrode 17 and the peripheral fixed contact 3, so that the multidirectional input device 1 b can It is possible to detect that the input operation is further pressed from the input operation in the direction and the input operation is performed outward in the radial direction. This is an input operation to the radially outer side of the second stage. The input operation to the radially outer side of the second stage is different from the input operation to the radially outer side of the first stage by pressing the second peripheral movable electrode 16 formed in a dome shape. Since it is performed with a click feeling, it is possible to prevent malfunctions with respect to two-stage input to the outside in the radial direction. In addition, when performing the second-stage input operation to the outside in the radial direction, it is possible to perform an operation with a good and light click feeling.

  That is, the multidirectional input device 1b according to the third embodiment can input in two stages in the pressing direction in the input operation to the outer side in the radial direction, and there is an effect that the convenience of the multidirectional input device 1b is improved.

(4) Fourth Embodiment As shown in FIG. 17, the multidirectional input device 1c according to the fourth embodiment has a fixed peripheral contact 3 and a movable peripheral for the casing 2 as in the first embodiment. Each member used for input in the circumferential direction such as the electrode 4 and the common electrode 5 for the periphery, the fixed contact 6 for the center, the movable electrode 7 for the center, and the input in the pressing direction in the center such as the common electrode 8 for the center. Each member, an operation member 9, a lid body 13, an elastic arm 14, and a restraining member 15 are provided. Here, the multi-directional input device 1 of the first embodiment is different from the multi-directional input device 1 in that the guide wall 2b of the housing 2 is formed with a height that does not contact the peripheral pressing member 12, and the center. That is, the movable electrode 7 is formed to have a recess 7c in a portion in contact with the central pressing portion 11d.

  Unlike the multidirectional input device 1 according to the first embodiment, the multidirectional input device 1c according to the fourth embodiment having the guide wall 2b and the central movable electrode 7 described above is slid during an input operation in the circumferential direction. The input operation can be performed by tilting movement instead of movement. Specifically, when the operation member 9 is tilted outward in the radial direction, the operation member 9 uses the contact point between the central pressing portion 11d and the recess 7c of the central movable electrode 7 as a rotation fulcrum, and the lid 13 is Since the peripheral pressing member 12 is slidably restrained in the circumferential direction as in the first embodiment, the peripheral pressing member 12 can be tilted while pressing the peripheral movable electrode 4. Accordingly, the multidirectional input device 1c according to the fourth embodiment is not limited to the input operation in the circumferential direction by the sliding movement of the operating body 10 like the multidirectional input device 1 according to the first embodiment, but the fourth direction. An input operation to the outside in the radial direction by tilting of the operating body 10 like the multidirectional input device 1c of the embodiment can be performed.

  That is, the multidirectional input devices 1, 1a, 1b, and 1c of the first to fourth embodiments described above can reduce variations in the operating force in the radially outward direction. The operation feeling of 1, 1a, 1b, 1c becomes good. Further, the reaction force adjusting portions 4c and 4d can be easily formed, and the guide wall 2b inside the housing 2 can be formed lower than the conventional one, so that the multidirectional input devices 1, 1a and 1b can be formed. There is an effect that the shape of 1c becomes compact. Furthermore, since the shape of the peripheral movable electrode 4 and the peripheral pressing member 12 is relatively simple, the manufacturing cost of the multidirectional input devices 1, 1a, 1b, 1c is reduced. . Then, by changing the shape of the guide wall 2b and the like, it is possible to perform two-stage input to the outside in the radial direction and to select an input operation by sliding and tilting.

  In addition, this invention is not limited to embodiment mentioned above etc., A various change is possible as needed.
