[0017] Hereinafter, an embodiment will be described with reference to the accompanying drawings. Furthermore, for convenience, in the following description, the Z-axis direction in the figures will be defined as the up-down direction, the Y-axis direction as the left-right direction, and the X-axis direction as the front-back direction. Specifically, the positive Z-axis direction will be defined as upward, the positive Y-axis direction as right, and the positive X-axis direction as forward.

[0018] (Overview of the multi-directional input device 100) Figure 1 This is a perspective view of a multi-directional input device 100 according to one embodiment. (See attached image.) Figure 1As shown, the multi-directional input device 100 has a housing 110 consisting of a lower base 111 and an upper cover 112 disposed on the upper side of the lower base 111. A circular opening 112A is formed in the center of the upper cover 112. A portion (operating part 141 and protrusion 142A) of a sliding member 140, which is capable of sliding in the forward-backward direction (X-axis direction) and the left-right direction (Y-axis direction), protrudes upward (positive Z-axis direction) from the opening 112A. Thus, the multi-directional input device 100 can receive sliding operations in the forward-backward direction (X-axis direction) and the left-right direction (Y-axis direction) and pressing operations downward (negative Z-axis direction) from the operator via the operating part 141 of the sliding member 140.

[0019] (Structure of the multi-directional input device 100) Figure 2 This is an exploded perspective view of a multi-directional input device 100 according to one embodiment. Figure 3 This is a cross-sectional view of a multi-directional input device 100 according to one embodiment. (See attached image.) Figure 2 and Figure 3 As shown, the multi-directional input device 100 includes a lower base 111, a sliding component 140, a swing component 120, four first rubber dome components 131, second rubber dome components 132, and an upper cover 112.

[0020] The lower base 111 is a container-shaped component with a generally rectangular parallelepiped shape. When viewed from above, the lower base 111 has a generally square shape. The lower base 111 has a recess 111B that is concave downwards from the upper surface 111A. When viewed from above, the recess 111B has a generally square shape that is slightly smaller than the generally square shape formed by the upper surface 111A. Four first rubber dome components 131, second rubber dome components 132, a swing component 120, and a sliding component 140 are housed inside the recess 111B. The lower base 111 is formed, for example, using a relatively hard insulating material (e.g., hard resin) by insert molding.

[0021] On a pair of parallel sides of the lower base 111, outwardly protruding claw portions 111C are formed. When the upper cover 112 is installed on the upper surface 111A of the lower base 111, the claw portions 111C are inserted into the opening of the hook 112B of the upper cover 112, thereby hooking the hook 112B and fixing the upper cover 112 relative to the lower base 111.

[0022] Four first switch portions 113 and second switch portions 114 are provided on the bottom surface 111Ba of the recess 111B of the lower base 111.

[0023] The second switch part 114 is disposed in the center of the bottom part 111Ba. The second switch part 114 is configured to have a fixed contact embedded in the bottom part 111Ba and a movable contact member made of metal and in the shape of a dome disposed on the upper side of the fixed contact.

[0024] Four first switch parts 113 are respectively disposed in the front-back direction (X-axis direction) and the left-right direction (Y-axis direction) with the center of the bottom part 111Ba as a reference. The four first switch parts 113 are respectively configured to have a fixed contact embedded in the bottom part 111Ba and a movable contact component made of metal in the shape of a tongue disposed on the upper side of the fixed contact.

[0025] The sliding member 140 is disposed inside the recess 111B of the lower base 111 on the upper side of the swing member 120, and is arranged in such a way that it can slide in the front-back direction (X-axis direction) and the left-right direction (Y-axis direction). The sliding member 140 is configured to have an operating part 141 and a base 142.

[0026] The operating part 141 is a resin-made, cylindrical component that accepts sliding and pressing operations from the operator. The operating part 141 passes through a through hole 142B formed in the protrusion 142A of the base 142 at the center of the sliding member 140, and is arranged to be movable in the vertical direction (Z-axis direction). A hemispherical protrusion 141A protruding downwards (negative Z-axis direction) is provided on the bottom surface of the operating part 141. Furthermore, an operating knob (not shown) can be mounted on the upper end of the operating part 141.

[0027] A base 142, disposed around the operating part 141, is a horizontal, flat (disc-shaped) resin component that supports the operating part 141. The base 142 has a cylindrical protrusion 142A protruding upwards (in the positive Z-axis direction) at its center. A through hole 142B is formed on the upper surface of the protrusion 142A. The base 142 supports the operating part 141 by inserting it into the through hole 142B, thereby enabling the operating part 141 to move vertically (in the Z-axis direction), and also supports it in a manner that allows it to slide integrally with the operating part 141 in the front-back (X-axis direction) and left-right (Y-axis direction).

[0028] Furthermore, the sliding member 140 is disposed on the lower side of the upper cover 112, but the protrusion 142A of the base 142 and the operating part 141 penetrate through the opening 112A of the upper cover 112, thereby protruding to a position above the upper cover 112 (positive Z-axis direction). Thus, the sliding member 140 can accept the operator's sliding and pressing operations.

[0029] The swing member 120 is a resin component that has a roughly cross-shaped appearance when viewed from above (positive Z-axis direction). The swing member 120 has four drive arms 121 extending from the central portion 120A in both the front-rear direction (X-axis direction) and the left-right direction (Y-axis direction). The swing member 120 is disposed inside the recess 111B of the lower base 111 on the lower side (negative Z-axis side) of the sliding member 140. The swing member 120 is configured to swing about the central portion 120A as its swing center in both the front-rear direction (X-axis direction) and the left-right direction (Y-axis direction).

[0030] The swing member 120 has a cylindrical central support portion 122 protruding upward from the central portion 120A, and a mortar-shaped recess 122A located at the upper end of the central support portion 122 engages with a protrusion 141A of the operating portion 141 of the sliding member 140. Thus, when the operating portion 141 of the sliding member 140 is slidably operated, the protrusion 141A of the operating portion 141 climbs up the slope of the recess 122A as the sliding member 140 slides, causing the swing member 120 to swing in the same direction as the sliding member 140. As a result, the swing member 120 can press a first rubber dome member 131 located in the swing direction via the front end of a drive arm portion 121 located in the swing direction.

[0031] Furthermore, the swing member 120 is configured to swing as described above. When the operating part 141 of the sliding member 140 is pressed, the swing member 120 is pressed downward on the protrusion 141A of the operating part 141, thereby allowing it to move downward (in the negative Z-axis direction) while maintaining a horizontal state. As a result, the swing member 120 can press the second rubber dome member 132 through the pressing surface 123 on the bottom part of the central part 120A.

[0032] Four first rubber dome components 131 are dome-shaped components made of elastic material, respectively disposed on the bottom part 111Ba of the recess 111B of the lower base 111, further forward and backward (X-axis direction) and left and right (Y-axis direction) than the central part. The four first rubber dome components 131 are respectively disposed on the upper side of the four first switch parts 113 disposed on the bottom part 111Ba and on the lower side of the four drive arms 121 of the swing member 120. When the operating part 141 of the sliding member 140 is slidably operated, one of the first rubber dome components 131 disposed in the sliding operation direction is pressed by the front end of a drive arm 121 disposed in the sliding operation direction and undergoes elastic deformation, thereby pressing one of the first switch parts 113 disposed in the sliding operation direction and switching that first switch part 113 to the on state. Furthermore, the four first rubber dome components 131 are an example of "four rebound parts".

[0033] The second rubber dome component 132 is a dome-shaped component made of elastic material, located at the center of the bottom portion 111Ba of the recess 111B of the lower base 111. The second rubber dome component 132 is positioned above the second switch portion 114 located on the bottom portion 111Ba and below the pressing surface 123 of the swing member 120. When the operating portion 141 of the sliding member 140 is pressed, the second rubber dome component 132 is pressed by the pressing surface 123 of the swing member 120 and undergoes elastic deformation, thereby pressing the second switch portion 114 and switching it to the on state. At this time, the four first rubber dome components 131 are pressed simultaneously by the four drive arms 121 of the swing component 120. Since the stroke of the second switch part 114 is smaller than the stroke of each of the four first rubber dome components 131, the four first rubber dome components 131 are not fully pressed, and therefore, the four first switch parts 113 do not switch to the on state.

[0034] The upper cover 112 is a horizontal, flat metal plate. The upper cover 112 is fixedly mounted to the upper surface 111A of the lower base 111, thereby closing the recess 111B of the lower base 111. The upper cover 112 is formed, for example, by processing a metal plate using a stamping process. Viewed from above, a circular opening 112A is formed in the center of the upper cover 112, allowing a portion of the sliding member 140 (operating portion 141 and protrusion 142A) to protrude upwards.

[0035] Additionally, a pair of parallel sides on the outer periphery of the upper cover 112 are each provided with a downwardly hanging hook 112B. The hook 112B has a rectangular opening, into which a claw portion 111C, located on the side of the lower base 111, is inserted (see reference). Figure 1 Thus, the hook 112B is hooked onto the claw portion 111C, which can fix the upper cover 112 relative to the lower base 111.

[0036] (Structure of the lower base 111) Figure 4 This is a perspective view of the lower base 111 of the multi-directional input device 100 according to one embodiment. Figure 5 This is a perspective view of the lower base 111 (with the swing member 120 arranged) of the multi-directional input device 100 according to one embodiment.

[0037] like Figure 4 As shown, a second rubber dome component 132 is provided in the center of the bottom part 111Ba of the recess 111B of the lower base 111, and a first rubber dome component 131 is provided in the front-back direction (X-axis direction) and the left-right direction (Y-axis direction).

[0038] And, as Figure 5 As shown, in the recess 111B of the lower base 111, the swing member 120 is arranged such that the central portion 120A of the swing member 120 is placed on the second rubber dome member 132 and the front ends of the four drive arm portions 121 of the swing member 120 are respectively placed on the four first rubber dome members 131.

[0039] Thus, in one embodiment of the multi-directional input device 100, when the operation part 141 of the sliding member 140 is slidably operated, the swing member 120 swings in the same direction as the sliding operation direction, and the front end of a drive arm 121 provided in the swing direction can be used to press a first rubber dome member 131 provided in the swing direction.

[0040] In addition, in one embodiment of the multi-directional input device 100, when the operation part 141 of the sliding member 140 is pressed, the swing member 120 moves downward while maintaining a horizontal state, and the second rubber dome member 132 can be pressed using the pressing surface 123 provided on the bottom part of the central part 120A of the swing member 120.

[0041] Here, as Figure 4 and Figure 5 As shown, four columnar support portions 151 are provided on the bottom surface 111Ba of the recess 111B of the lower base 111. The four columnar support portions 151 constitute a support mechanism 150, which supports the swing member 120 in such a way that the swing member 120 can swing in the front-back direction (X-axis direction) and the left-right direction (Y-axis direction).

[0042] Four columnar support portions 151 extend integrally with the bottom portion 111Ba upward from the bottom portion 111Ba. The four columnar support portions 151 are respectively provided at the inner corner (i.e., "inner corner") between two adjacent drive arm portions 121 of the swing member 120. The four columnar support portions 151 can abut against the side edge portions 121A of the two adjacent drive arm portions 121 of the swing member 120 through two L-shaped abutment surfaces 151A (i.e., "receiving portions") viewed from above.

[0043] Therefore, the multi-directional input device 100 of one embodiment can limit the positional displacement of the swing member 120 in the horizontal and rotational directions and guide the swing member 120 to swing in the forward-backward (X-axis) and left-right (Y-axis) directions by means of the four columnar support portions 151. In particular, since the multi-directional input device 100 of one embodiment has four columnar support portions 151 integrally provided on the lower base 111, the number of components of the multi-directional input device 100 can be reduced.

[0044] In addition, the four drive arms 121 of the swing member 120 are respectively disposed between the two columnar support portions 151 (i.e., between the two abutment surfaces 151A), and the swing of the drive arms 121 is guided by abutting the two side edges 121A with the two abutment surfaces 151A.

[0045] Furthermore, the four columnar support portions 151 are an example of an "integral support portion". The "integral support portion" is integrally provided from the lower base 111 in the front-back and left-right directions of the swing member 120, and has a receiving portion for the side edge of the swing member 120 to abut in the front-back and left-right directions so that the side edge of the swing member 120 can slide downward.

[0046] Figure 6 This is a perspective sectional view of a multi-directional input device 100 according to one embodiment, cut by a vertical plane. For example... Figure 4 and Figure 5 As shown, two of the four columnar support portions 151, 151-1 and 151-2, have horizontal sliding support surfaces 151B at their upper ends. Furthermore, as... Figure 6 As shown, the base 142 of the sliding member 140 is supported in a manner that allows it to slide between the upper cover 112 and the sliding support surface 151B of the two columnar support portions 151-1 and 151-2.

[0047] Thus, in the multi-directional input device 100 of one embodiment, the two columnar support portions 151-1 and 151-2 integrally provided on the lower base 111 also have the function of slidably supporting the sliding member 140 from the lower side through the sliding support surface 151B. Therefore, there is no need to provide a separate support member to support the sliding member 140, thereby reducing the number of components in the multi-directional input device 100.

[0048] Figure 7 This is a perspective sectional view of a multi-directional input device 100 according to one embodiment, cut by a horizontal plane. For example... Figure 4 and Figure 5 As shown, two of the four columnar support portions 151, 151-3 and 151-4, have guide protrusions 151C at their upper ends.

[0049] On the other hand, such as Figure 7 As shown, the base 142 of the sliding member 140 has two cross-shaped grooves 143 extending along the front-rear direction (X-axis direction) and the left-right direction (Y-axis direction) on its bottom surface. Furthermore, as... Figure 7 As shown, the sliding member 140 is supported by inserting the guide protrusions 151C of the two columnar support portions 151-3 and 151-4 into the two cross-shaped groove portions 143 respectively, so that it can only slide in the front-back direction (X-axis direction) and the left-right direction (Y-axis direction).

[0050] Thus, in the multi-directional input device 100 of one embodiment, the two columnar support portions 151-3 and 151-4 integrally provided on the lower base 111 also have the function of guiding the sliding member 140 in the front-back direction (X-axis direction) and left-right direction (Y-axis direction) through the guide protrusion 151C. Therefore, there is no need to provide a separate support member to guide the sliding member 140, thereby reducing the number of components in the multi-directional input device 100.

[0051] Figure 8 This is a perspective view of the operation section 141 and the swing member 120 of the multi-directional input device 100 according to one embodiment, viewed from above. Figure 9 This is a perspective view of the operation section 141 and the swing member 120 of the multi-directional input device 100 according to one embodiment, viewed from below.

[0052] like Figure 8 As shown, the central support portion 122 of the swing member 120 has a groove 161, which has a cut formed from the upper end downwards, extending horizontally around the mortar-shaped recess 122A, and appearing cross-shaped when viewed from above. On the other hand, as Figure 9As shown, a plate-shaped portion 162 is provided on the bottom surface of the operation portion 141 of the sliding member 140. The plate-shaped portion 162 extends horizontally with the hemispherical protrusion 141A as the center and appears cross-shaped when viewed from below.

[0053] Furthermore, when the sliding member 140 is positioned between the swing member 120 and the upper cover 112 and engages with the central support portion 122 of the swing member 120, the plate-shaped portion 162 of the operating portion 141 is inserted into the groove 161 provided in the central support portion 122 of the swing member 120.

[0054] Thus, the multi-directional input device 100 of one embodiment can slidably support the sliding member 140 by the swing member 120, and can prevent the operating part 141 from rotating in the direction about the central axis.

[0055] Here, the recess 122A of the swing member 120 and the protrusion 141A of the sliding operation part 141 are pivotally connected to each other, thereby forming a transmission part 160 that transmits power from the operation part 141 in the front-back direction (X-axis direction) and the left-right direction (Y-axis direction) to the swing member 120. Furthermore, the transmission part 160 has an anti-rotation part 160A formed by the groove 161 of the swing member 120 and the plate-shaped part 162 of the operation part 141.

[0056] Alternatively, contrary to this embodiment, the groove 161 may be provided on the operation part 141, and the plate-shaped part 162 may be provided on the swing member 120.

[0057] Furthermore, the four grooves of the groove portion 161 and the four plates of the plate portion 162 extend in a direction offset by 45° from the front-back direction (X-axis direction) and the left-right direction (Y-axis direction) (i.e., the "inclination direction").

[0058] Therefore, the multi-directional input device 100 of one embodiment can reduce the tilt of the plate-shaped portion 162 when the swing member 120 swings, and thus can reduce the gap between the plate-shaped portion 162 and the groove portion 161.

[0059] Figure 10 This is a perspective sectional view of a multi-directional input device 100 according to one embodiment, cut with a vertical plane.

[0060] like Figure 10 As shown, the two side edges 121A of the drive arm portion 121 have abutment slopes 121Aa that are shorter on the lower side and longer on the upper side than on the abutment surface 151A of the opposing columnar support portion 151. Furthermore, since the four drive arm portions 121 are identical in shape, both side edges 121A have abutment slopes 121Aa.

[0061] Thus, in one embodiment of the multi-directional input device 100, when the swing member 120 swings in the front-back direction (X-axis direction), the two drive arms 121 extending in the left-right direction (Y-axis direction) rotate about the left-right direction (Y-axis direction) axis respectively. However, at this time, the two side edges 121A of each of the two drive arms 121 extending in the left-right direction (Y-axis direction) have abutting inclined surfaces 121Aa, thereby suppressing interference with the abutting surface 151A of the columnar support 151, and not hindering the swing member 120 from swinging in the front-back direction (X-axis direction).

[0062] Similarly, in one embodiment of the multi-directional input device 100, when the swing member 120 swings in the left-right direction (Y-axis direction), the two drive arms 121 extending in the front-back direction (X-axis direction) rotate about the axis in the front-back direction (X-axis direction). However, at this time, the side edges 121A of each of the two drive arms 121 extending in the front-back direction (X-axis direction) have abutting inclined surfaces 121Aa, thereby suppressing interference with the contact surface 151A of the columnar support 151, and not hindering the swing member 120 from swinging in the front-back direction and the left-right direction (Y-axis direction).

[0063] The above describes one embodiment of the present invention in detail, but the present invention is not limited to these embodiments, and various modifications or alterations can be made within the scope of the spirit of the present invention as set forth in the claims.
