  The substantial center of the tilt detection part is located outside the inner surface of the outer wall. This has contributed to the increase in size of the input device.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an input device that can be miniaturized.

  In order to solve the above problems, an input device according to the present invention includes an operation unit, a tilt detection unit, first and second leg units, first and second arms, and a first pressing unit. . The operation unit can tilt. The operation portion has an outer wall having an inner surface and an outer surface. The tilt detection unit is a detection unit capable of detecting a tilt of the operation unit in a predetermined direction. The tilt detection unit is disposed in a region on the predetermined direction side of the operation unit below the outer wall, and at least a substantially center is located inside the inner surface of the outer wall.

  In the case of such an input device, at least the approximate center of the tilt detection unit is located on the inner side of the inner surface of the outer wall of the operation unit. The first pressing portion is disposed so that the force point portion of the first pressing portion is located below the outer wall, and at least approximately the center of the action point portion of the first pressing portion is located inside the inner surface of the outer wall. . For this reason, since the tilt detection unit and the first pressing unit can be arranged inside the input device as compared with the conventional example, the input device can be reduced in size. In addition, since the action point portion is located on the inner side of the force point portion, the load applied to the force point portion of the first pressing portion is suitably transmitted to the tilt detection portion based on the lever principle.

On the other hand, at least a part of the inclined arms of the first and second arms extends inside the outer wall. For this reason, when the 1st pushing part inclines to the outer side of an outer wall, a part or whole of the inclination arm of a 1st, 2nd arm inclines inside an outer wall. In other words, since the first pressing portion and the inclined arms of the first and second arms are partially or entirely inclined in an opposite direction, the outer wall is prevented from dropping from the first pressing portion when the operation portion is tilted. be able to.

In this way, the operation unit 100 is held by the first holding unit 200 so as to be rotatable and tiltable in any surrounding direction.

  Thereafter, the first and second leg portions 220 a and 220 b of the second holding unit 200 are fixed to the substrate 600 and the reinforcing plate 700. Then, the contact arm 822a of the brush 820a elastically contacts the mounting surface of the substrate 600.

Accordingly, the first and second pressing portions 250 and 260 are disposed between the tilt detection portion 800b and the outer wall 130.

  Thereafter, the second holding unit 500 is prepared. Thereafter, the second holding unit 500 is inserted into the inner wall 120 of the operation unit 100. In this state, the substrate 600 and the reinforcing plate 700 are fixed. Thereafter, a pressing operation unit 400 is prepared.

In this way, the pressing operation unit 400 is held by the second holding unit 500 so as to be able to be pressed.

  Hereinafter, the usage method of the input device D and the operation of each component will be described. When the operation unit 100 is rotated in the circumferential direction at the initial position, the inner wall 120 of the operation unit 100 rotates while being in sliding contact with the sliding contact surface 211 a of the bearing unit 210 of the first holding unit 200. For this reason, the operation unit 100 rotates in the circumferential direction around the inner wall 120 with almost no backlash. As the operation unit 100 rotates, the brush 820a rotates in the circumferential direction, and the contact arm 822a of the brush 820a slides on the substrate 600 to selectively contact the fixed contact 810a on the substrate 600. Accordingly, a signal corresponding to the rotation angle of the operation unit 100 is output to the electronic device. In addition, with the rotation of the operation unit 100, the feeler 300 rotates, and the pair of spring portions 320 of the feeler 300 moves in amplitude on the convex recess 211 d of the bearing portion 210 of the first holding portion 200. Thereby, an operational feeling is generated in the rotation operation of the operation unit 100.

  When the key top 140 of the operation unit 100 in the initial position or the key top 530 of the second holding unit 500 is tilted in the Y1 direction or the Y2 direction (see FIG. 5A), it is opposite to the tilting direction of the fixing plate 160 of the operation unit 100. The part where the side (Y2 direction or Y1 direction) is in contact with the part opposite to the tilt direction (Y2 direction or Y1 direction) of the protrusion 211c of the first holding part 200 functions as a fulcrum of the operation part 100. On the other hand, the portion on the tilt direction side (Y1 direction or Y2 direction side) of the fixed plate 160 of the operation unit 100 is separated from the portion on the tilt direction side (Y1 direction or Y2 direction side) of the protrusion 211c of the first holding unit 200. To do. As a result, the inner wall 120 of the operation unit 100 is inclined with respect to the bearing unit 210 of the first holding unit 200. Since the tapered surface 211b is provided on the upper side of the sliding contact surface 211a of the upper step portion 211 of the bearing portion 210, interference between the inner wall 120 and the upper step portion 211 of the bearing portion 210 is avoided. At the same time, as shown in FIG. 5B and FIG. 6B, the first pressing of the first holding unit 200 where the portion on the tilt direction side of the outer wall 130 of the operation unit 100 is located on the tilt direction side (Y1 direction or Y2 direction side). The power point part 253 of the part 250 is pressed. That is, a load is applied to the power point portion 253 by the outer wall 130. As a result, the first pressing portion 250 is inclined to the outside (Y1 direction or Y2 direction side) of the outer wall 130 with the first and second arms 230a and 230b as fulcrums, and the action point portion 254 of the first pressing portion 250 is The tilt detector 800b located on the tilt direction side (Y1 direction or Y2 direction side) is pressed. Specifically, a load is applied to the top of the movable contact 820b of the tilt detection unit 800b by the action point 254, the movable contact 820b is elastically deformed, and the top of the movable contact 820b contacts the fixed contact 812b. As a result, a signal indicating the tilt of the operation body 100 in the Y1 direction or the Y2 direction is output to the electronic device. The first and second arms 230a and 230b are elastically deformed from the initial state so that the inclined arms 232a and 232b are inclined inward (Y2 direction or Y1 direction) according to the inclination of the first pressing part 250. .

  Thereafter, when the key top 140 of the operation unit 100 or the key top 530 of the second holding unit 500 is released, the movable contact 820b on the tilt direction side (Y1 direction or Y2 direction side) is restored, and the tilt direction side (Y1 direction) is restored. Alternatively, the action point portion 254 of the first pressing portion 250 on the Y2 direction side is pushed up. As a result, the force point portion 253 of the first pressing portion 250 pushes up the portion of the outer wall 130 on the tilt direction side (Y1 direction or Y2 direction side). Then, the portion on the tilting direction side (Y1 direction or Y2 direction side) of the fixed plate 160 of the operation unit 100 contacts the portion on the tilting direction side (Y1 direction or Y2 direction side) of the protrusion 211c of the first holding unit 200. Touch. As a result, the fixed plate 160 and the ridge 211c abut over the entire circumference, and the operation unit 100 returns to the initial position.

  When the key top 140 of the operation unit 100 in the initial position or the key top 530 of the second holding unit 500 is tilted in the X1 direction or the X direction (see FIG. 5B), the tilting direction of the fixing plate 160 of the operation unit 100 is opposite. The portion where the side (X2 direction or X1 direction) is in contact with the portion (X2 direction or X1 direction) opposite to the tilting direction of the ridge 211c of the first holding unit 200 functions as a fulcrum of the operation unit 100. On the other hand, the portion on the tilting direction side (X1 direction or X2 direction side) of the fixed plate 160 of the operation unit 100 is separated from the portion on the tilting direction side (X1 direction or X2 direction side) of the protrusion 211c of the first holding unit 200. To do. As a result, the inner wall 120 of the operation unit 100 is inclined with respect to the bearing unit 210 of the first holding unit 200. Since the tapered surface 211b is provided on the upper side of the sliding contact surface 211a of the upper step portion 211 of the bearing portion 210, interference between the inner wall 120 and the upper step portion 211 of the bearing portion 210 is avoided. At the same time, the portion on the tilt direction side of the outer wall 130 of the operation unit 100 presses the force point portion 263 of the second pressing portion 260 of the first holding unit 200 located on the tilt direction side (X1 direction or X2 direction side). That is, a load is applied to the force point portion 263 by the outer wall 130. As a result, the second pressing portion 260 is inclined outward (X1 direction or X2 direction side) of the outer wall 130 with the third and fourth arms 240a and 240b as fulcrums, and the action point portion 264 of the second pressing portion 260 is The tilt detector 800b located on the tilt direction side (X1 direction or X2 direction side) is pressed. Specifically, a load is applied to the top of the movable contact 820b of the tilt detection unit 800b by the action point 264, the movable contact 820b is elastically deformed, and the top of the movable contact 820b contacts the fixed contact 812b. As a result, a signal indicating the tilt of the operating body 100 in the X1 direction or the X2 direction is output to the electronic device. According to the inclination of the second pressing part 260, the third and fourth arms 240a, 240a, 240b, so that the third and fourth arms 240a, 240b are inclined to the inside (X1 direction or X2 direction) of the outer wall 130 while being twisted. 240b is elastically deformed from the initial state.

  After that, when the key top 140 of the operation unit 100 or the key top 530 of the second holding unit 500 is released, the movable contact 820b on the tilt direction side (X1 direction or X2 direction side) is restored, and the tilt direction side (X1 direction) Alternatively, the action point portion 264 of the second pressing portion 260 on the X2 direction side is pushed up. As a result, the force point portion 263 of the second pressing portion 260 pushes up the portion of the outer wall 130 on the tilt direction side (X1 direction or X2 direction side). Then, the portion on the tilting direction side (X1 direction or X2 direction side) of the fixed plate 160 of the operation unit 100 contacts the portion on the tilting direction side (X1 direction or X2 direction side) of the protrusion 211c of the first holding unit 200. Touch. As a result, the fixed plate 160 and the ridge 211c abut over the entire circumference, and the operation unit 100 returns to the initial position.

  When the pressing operation unit 400 at the origin position is pressed in the Z2 direction, the runner 430 of the pressing operation unit 400 moves in the Z2 direction in the guide hole 511 of the second holding unit 500, and the pressing operation unit 400 is engaged. The piece 420 moves to the engagement hole 512 of the second holding unit 500 in the Z2 direction. Then, the protrusion 440 of the pressing operation unit 400 presses the top of the movable contact 820c of the pressing movement detection unit 800c. That is, when a load is applied to the top of the movable contact 820c, the movable contact 820c is elastically deformed, and the top of the movable contact 820c contacts the fixed contact 812c. Thereby, a signal indicating the pressing movement of the operation body 100 in the X1 direction or the X2 direction is output to the electronic device through the fixed contacts 811c and 812c.

  In the case of such a composite operation type input device, the approximate center of the tilt detection unit 800b is located inside the inner surface 131 of the outer wall 130 of the operation unit 100. The first pressing portion 250 is such that the force point portion 253 of the first pressing portion 250 is positioned below the outer wall 130 and the approximate center of the action point portion 254 of the first pressing portion 250 is positioned inside the inner surface 131 of the outer wall 130. Is arranged. As described above, since the tilt detection unit 800b and the first pressing unit 250 are arranged inside the input device D, the size of the substrate 600 in the Y1-Y2 direction can be reduced, and the input device D can be downsized. Can do. Moreover, since the action point portion 254 is located on the inner side of the force point portion 253, the load applied to the force point portion 253 of the first pressing portion 250 is suitably transmitted to the tilt detection portion 800b based on the lever principle. Therefore, even if the tilt detection unit 800b is arranged so that its approximate center is located on the inner side of the inner surface 131 of the outer wall 130 of the operation unit 100, a decrease in detection accuracy of the tilt detection unit 800b is suppressed.

  Further, when a load is applied to the force application point 253 of the first pressing part 250, the first pressing part 250 is inclined to the outside of the outer wall 130, while the first and second arms 230 a and 230 b have the inclined arms 232 a and 232 b. The inclined arm bodies 232a1 and 232b1 are inclined inward of the outer wall 130. That is, since the first pressing portion 250 and the inclined arms 232a and 232b of the first and second arms 230a and 230b are inclined in the opposite direction, the outer wall 130 is moved to the first pressing portion when the operation unit 100 is tilted.

That is, a load is applied to the force point portion 263 by the outer wall 130. As a result, the second pressing portion 260 is inclined outward (X1 direction or X2 direction side) of the outer wall 130 with the third and fourth arms 240a and 240b as fulcrums, and the action point portion 264 of the second pressing portion 260 is The tilt detector 800b located on the tilt direction side (X1 direction or X2 direction side) is pressed. Specifically, a load is applied to the top of the movable contact 820b of the tilt detection unit 800b by the action point 264, the movable contact 820b is elastically deformed, and the top of the movable contact 820b contacts the fixed contact 812b. Thereby, a signal indicating the tilt of the operation unit 100 in the X1 direction or the X2 direction is output to the electronic device. The third and fourth arms 240a, 240a, 240b are inclined so that the third and fourth arms 240a, 240b are inclined to the inside ( X2 direction or X1 direction ) while being twisted according to the inclination of the second pressing portion 260. 240b is elastically deformed from the initial state.

When the pressing operation unit 400 at the origin position is pressed in the Z2 direction, the runner 430 of the pressing operation unit 400 moves in the Z2 direction in the guide hole 511 of the second holding unit 500, and the pressing operation unit 400 is engaged. The piece 420 moves to the engagement hole 512 of the second holding unit 500 in the Z2 direction. Then, the protrusion 440 of the pressing operation unit 400 presses the top of the movable contact 820c of the pressing movement detection unit 800c. That is, when a load is applied to the top of the movable contact 820c, the movable contact 820c is elastically deformed, and the top of the movable contact 820c contacts the fixed contact 812c. Accordingly, a signal indicating the pressing movement of the operation unit 100 in the X1 direction or the X2 direction is output to the electronic device through the fixed contacts 811c and 812c.
