FIG. 43 is a graph showing the relationship between the tilting angle (rotating angle) of the operating member 66 and the operating force. As shown in FIG. 43, at the initial stage of tilting, a large operating force due to the biasing force (spring pressure) of the return means 68 is applied to form a steep first change curve H1, and then the tilting operation is continued, In the operating area, the operating member 67 is moved forward. This is because the length of the arm portion between the change of the biasing force (spring pressure) of the return means 68 and the operating point of the operating member 66 from the rotation center to the bottom plate 68a of the flange-shaped portion 67b gradually decreases. With the displacement of the rotational torque, a second change curve H2 having a constant displacement amount (the slope of the graph in the operating region) shown in FIG. 43 is obtained. In addition, the coil spring which is the return means 68 is compressed in a state where the effective spring length is not changed by the forward movement of the actuating member 67 and the winding portions formed at equal intervals are contracted. ing.

  Next, when the operation member 66 in the neutral state is tilted (rotated) against the urging force of the return means 68 as shown in FIG. As a result, the rotation angle detection member 52 is operated by the rotation of the rotating body 56, an electrical signal is output, and the operation member 66 is tilted (rotation operation). Is released, the operating member 66 and the first drive member 64 are returned to the neutral state by the return means 68. Also in this operation, the operating member 66 can obtain an operating force based on the same principle as described above, and the operating force of the operating member 66 becomes the first and second change curves H1 and H2, as shown in FIG. ing.

Next, when the operating member 66 is pressed in the direction of the arrow C against the urging force of the return means 68 in the state shown in FIGS. 40 and 42, the second driving member 65 is pressed by the shaft support portion 66d, and the second driving member 65 is pressed. The driving member 65 moves in the direction of arrow C with the engaging portion 65c as a fulcrum. As a result, the pressing portion 65d presses the stem 63, and the push switch 60 is operated (ON or OFF). When the pressing of the operation member 66 is released, the operation member 66 and the second drive member 65 are returned to the original state by the return means 68, and the stem 63 of the push switch 60 is also returned to the original state (for example, see Patent Document 1). ).

Further, the shaft support portion 24 of the operation member 23 spreads the second support body 20b while the guide surface 24c is guided by being brought into contact with the second support body 20b of the second drive member 18, and FIG. 26, the operation member 23 is fitted in the hole 21 of the second drive member 18 and can be tilted in the directions of the arrow A and the arrow B with the shaft support 24 as a fulcrum (rotation center) ( The first and second drive members 17 and 18 are tilted (rotated) by the tilting operation (rotating operation) of the operation member 66, and thereby the rotation angle is detected. When the operation of the member 2 is performed and the operation member 23 is further pressed in the direction of arrow C, the second driving member 18 is pressed by the shaft support portion 24 and the push switch 13 is operated.

  As shown in FIGS. 25 and 26, the shaft support structure of the shaft support portion 24 and the bearing portion 19 is such that the shaft support portion 24 is fitted in the hole portion 21 and the front side shaft portion 24a is the first support body. The rear side shaft portion 24b is supported by the second guide inner surface 21b provided on the second support 20b, and the shaft support portion 24 is thereby supported by the first guide inner surface 21a provided on the second support 20b. The first and second guide inner surfaces 21a and 21b are displaced inward and outward in the axial direction. Furthermore, the operation member 23 is assembled into the second drive member 18 by first inserting the operation member 23 from the lower side of the hollow portion 18a and positioning the pair of shaft support portions 24 between the pair of second supports 20b. In this state, when the operating member 23 is pressed upward, the shaft support portion 24 pushes the pair of second support bodies 20b outward while being guided by the guide groove 22, and the shaft support portion 24 enters the hole portion 21. When they match, when the pair of second support bodies 20b return due to the spring property, the shaft support portion 24 is fitted into the hole portion 21 and snapped.

(Configuration of actuating member)
As shown in FIG. 27, the actuating member 25 made of a synthetic resin molded product has a cylindrical part 25a and a dish-like bowl-shaped part 25b provided at the lower part (rear part) of the cylindrical part 25a. As shown in FIGS. 2 and 3, the member 25 has a cylindrical portion 25a positioned in the cylindrical portion 23c of the operation member 23, and the flange 25b is in contact with the bottom plate 11a. The shaft portion 23b is inserted and attached to the shaft portion 23b so as to be movable up and down (back and forth), and the return means 26 made of a coil spring operates with the operation member 23 in a state of being disposed in the cylindrical portion 23c. The return means 26 is disposed between the member 25 and the return member 26 urges the flange 25b toward the bottom plate 11a and urges the operation member 23 upward (forward) so that the operation member 23 becomes the bottom plate. Maintain a neutral state (not actuated) perpendicular to 11a It has become way.

  When the operating member 23 tilts, the actuating member 25 moves along with the operating member 23 while the hook-shaped portion 25b rides on the protruding portion 11b and changes the contact position with the bottom plate 11a. As a result, the operating member 23 is provided with an operating force by the return means 26, and the stopper structure for the tilting operation of the operating member 23 is operated as shown in FIGS. The member 23 is abutted against the panel 27 of the electronic device, and further tilting operation is prevented. Note that the stopper structure of the operation member 23 is such that the operation member 23 does not collide with the front end of the frame body 1 even when the operation member 23 is tilted to the maximum extent before the device is incorporated into the electronic device. The members such as the actuating member 25 are prevented from moving in the frame body 1, so that the stopper structure is replaced by the actuating member 25 in the frame body 1 instead of the panel 27. It is good also as a structure which prevents the tilting operation | movement of the operation member 23 in the frame 1 using members, such as. Further, the return means 26 will be described. As shown in FIG. 29, the coil spring forming the return means 26 is wound in a cylindrical shape so that the pitch between the wound portions gradually increases from the top to the bottom. When the operation member 23 is tilted at a predetermined tilt angle, adjacent winding portions are sequentially overlapped to form the multidirectional input device of the present invention.

(Operation of the operation member in the direction of arrow A)
Next, the operation of the multi-directional input device of the present invention having such a configuration will be described. As shown in FIG. 3, the operation member 23 in the neutral state is moved in the direction of arrow A against the urging force of the return means 26. When tilting (turning), as shown in FIG. 5, the second drive member 18 is turned by the operation member 23, and as a result, the rotation angle detection member 2 is operated by the rotation of the rotating body 7. When an electrical signal is output and the tilting operation (rotation operation) of the operation member 23 is released, the operation member 23 and the second drive member 18 return to the neutral state as shown in FIG. . In this operation, during the tilting operation, the rotating body 7 is rotated against the urging force of the return member 9, but when it returns to the neutral state, the return member 9 is different from the return means 26. The rotating body 7 is surely returned to the initial position.

(Operating force of the operating member)
The biasing force (spring pressure) of the return means 26 during the tilting operation (rotating operation) of the operation member 23 and the biasing force (spring pressure) of the return means 26 accompanying the forward movement during the tilting operation of the operating member 25. ) And the length between the rotation center K of the operating member 23 and the point of application of the flange 25b of the actuating member 25 to the bottom plate 11a is the arm portion (the length of the arm portion is the length of the operating member 23). The operating force is obtained in the operating member 23 by the rotational torque (which becomes shorter as the tilt angle becomes larger). Next, the operating force of the operating member 23 will be described. FIG. FIG. 29 is an explanatory diagram for explaining the operating force of the operating member 23, and FIG. 30 is a graph showing the relationship between the tilting angle (rotating angle) of the operating member 23 and the operating force. First, as shown in FIG. 29A and FIG. Operation The initial stage of the tilting member 23, a first variation curve H1 steep working large actuating force generated by the biasing force (spring force) of the return means 26.

  Next, the tilting operation is continued, and in the operation region of the operation member 23, the change in the urging force (spring pressure) of the return means 26 accompanying the forward movement of the operation member 25 and the operation member 23 in FIGS. 29A to 29B. 30 and the amount of displacement shown in FIG. 30 (the graph in the operation region) due to the displacement of the rotational torque due to the length of the arm portion between the rotation center K and the point of application of the flange 25b to the bottom plate 11a. The second change curve H2 having a constant inclination). The coil spring which is the return means 26 in the second change curve H2 is in a state where the effective spring length does not change due to the forward movement of the actuating member 25 and the winding portions formed at different pitches are contracted. It is in a compressed state.

  If the tilting operation is further continued, as shown in FIGS. 29B to 29C, from the predetermined tilting angle of the operation member 23, the winding portion located at the uppermost portion sequentially overlaps with the next winding portion. Thus, the second curve H2 shown in FIG. 30 is changed (changed) in the direction in which the amount of displacement increases, and becomes a third change curve H3. The coil spring, which is the return means 26 in the third change curve H3, gradually changes so that the winding portions are sequentially overlapped and the effective spring length is shortened due to the forward movement of the operating member 25. As a result, the urging force (spring pressure) is increased to form the third change curve H3. Thus, the operating force in the operating region of the operating member 23 includes a second curve H2 having a constant displacement amount, a third curve H3 that is variable in a direction in which the displacement amount of the second curve H2 increases, A third curve H3 having a constant displacement amount is obtained, so that the operating force changes greatly between the second and third change curves H2 and H3. In addition, this coil spring may reverse the attachment form, and may be made to overlap from the winding part of a lower side sequentially upwards.

(Operation of the operation member in the direction of arrow B)
Next, as shown in FIG. 2, when the operation member 23 in the neutral state is tilted (rotated) in the direction of arrow B against the urging force of the return means 26, the operation member 23 performs the first operation as shown in FIG. 4. As a result, the rotation angle detecting member 2 is operated by the rotation of the rotating body 7, and an electrical signal is output, and the tilting operation (rotating operation) of the operating member 23 is performed. Is released, the operating member 23 and the first drive member 17 are returned to the neutral state by the return means 26. In this operation, during the tilting operation, the rotating body 7 is rotated against the urging force of the return member 9, but when it returns to the neutral state, the return member 9 separate from the return means 26 acts. The rotating body 7 is surely returned to the initial position. Further, also in this operation, the operating member 23 can obtain an operating force based on the same principle as described above, and the operating force of the operating member 23 can be changed to the first, second, and third change curves as shown in FIG. H1, H2, and H3 are obtained. In the above description, the tilting operation in the arrow A direction and the arrow B direction has been described. However, the tilting operation of the operation member 23 can be performed in all tilting ranges other than the arrow A direction and the arrow B direction. Of course.

(Operation of the operation member in the direction of arrow C)
Next, when the operating member 23 is pressed in the direction of arrow C against the urging force of the return means 26 in the state shown in FIG. 2 or FIG. 3, the second drive member 18 is pressed by the shaft support portion 24, The second driving member 18 moves in the direction of arrow C with the engaging portion 18b as a fulcrum. As a result, the pressing portion 18c presses the stem 16 and the push switch 13 is operated (ON or OFF). When the pressing of the operation member 23 is released, the operation member 23 and the second drive member 18 are returned to the original state by the return means 26, and the stem 16 of the push switch 13 is also returned to the original state by the movable contact or the like.

(Another embodiment of the operating force of the operating member)
FIG. 31 is an explanatory view showing a first other embodiment for obtaining the operating force of the operating member of the present invention. When this first other embodiment is described, the coil spring as the return means 26 is: Since it is wound in a conical shape and the other configuration is the same as that of the above embodiment, the description thereof is omitted here.

  FIGS. 32 and 33 are explanatory views showing a second other embodiment for obtaining the operating force of the operating member of the present invention. When the second other embodiment is described, the return means 26 includes: While having the 1st, 2nd elastic members 26a and 26b which consist of a coil spring with the pitch between winding parts of equal intervals, the 1st elastic member 26a is formed with the 1st coil spring, and the 2nd The elastic member 26b is formed of a second coil spring, and the first elastic member 26a, which is the first coil spring, is a front end portion (upper end portion) in the cylindrical portion 23c of the operation member 23 to which the operating member 25 is fitted. ) And the front end portion (upper end portion) of the actuating member 25, and the second elastic member 26b, which is the second coil spring, is provided at the rear portion of the cylindrical portion 23c of the operation member 23. Between the step 23d and the rear end of the actuating member 25 The first elastic member 26a is in a state in which the operation member 23 is constantly urged upward, while the second elastic member 26b is provided with a predetermined distance from the step portion 23d. 23 and the actuating member 25 are arranged with play (a state in which the operation member 23 is not biased).

  Then, at the initial stage of tilting of the operation member 23, a large operating force due to the biasing force (spring pressure) of the first elastic member 26a is applied to obtain a steep first change curve H1 shown in FIG. In the operation region of the operation member 23, in FIG. 32 to FIG. 33, the change in the urging force (spring pressure) of the first elastic member 26 a accompanying the forward movement of the operation member 25, The amount of displacement shown in FIG. 30 (the slope of the graph in the operating region) is constant due to the displacement of the rotational torque with the length between the center of rotation K and the point of action of the bowl-shaped portion 25b acting on the bottom plate 11a as the arm portion. The second change curve H2. The first coil spring, which is the first elastic member 26a in the second change curve H2, has a space between the winding portions formed at equal pitches due to the forward movement of the actuating member 25, thereby reducing the effective spring. It is in a compressed state with the length unchanged.

  When the tilting operation is further continued, from the predetermined tilting angle of the operation member 23, as shown in FIG. 33, in addition to the gradual compression of the first elastic member 26a, the second elastic member 26b is stepped portion 23d. 30 is changed (changed) in the direction in which the displacement amount of the second curve H2 shown in FIG. 30 increases to become a third change curve H3. In the second coil spring, which is the second elastic member 26b in the third change curve H3, the space between the winding portions formed at equal pitches is reduced by the forward movement of the operating member 25, so that the effective spring It is in a compressed state with the length unchanged. As described above, the operating force in the operating region of the operating member 23 includes the second curve H2 having a constant displacement due to the biasing force of the first elastic member 26a, and the displacement of the second curve H2 being the second. A third curve H3 that is variable in an increasing direction by the addition of the urging force of the elastic member 26b and a third curve H3 with a constant amount of displacement are obtained. Therefore, the operating force is the second and third change curves H2, H2. It changes greatly between H3. In addition, in this Example, although demonstrated with the coil spring which has the pitch between the winding parts of equal intervals, for example, the coil spring from which a pitch differs is used for the 1st coil spring which is the 1st elastic member 26a, After the third change curve H3 having a large change amount shown in FIG. 30, the winding amount of the third curve H3 shown in FIG. It may be variable (changed) to obtain a fourth change curve H4, whereby the amount of displacement of the operating force may be made variable.

  FIG. 34 and FIG. 35 are explanatory views showing a third other embodiment for obtaining the operating force of the operating member of the present invention. The third other embodiment will be described. The first elastic member 26a and a second elastic member 26b having a higher elastic force than the first elastic member 26a are configured, and the actuating member 25 is provided with a receiving member 28 that can move up and down (displace). The first elastic member 26 a is disposed between the front end portion (upper end portion) in the cylindrical portion 23 c of the operation member 23 and one end portion of the receiving member 28, and the second elastic member 26 b is the operating member 25. And the other end portion of the receiving member 28, and the cylindrical portion 23 c is provided with a stepped portion 23 e with a predetermined distance from the other end portion of the receiving member 28. 23 is urged upward by the first elastic member 26a and the receiving member 2 The first, second elastic members 26a, the spring pressure of 26b are stopped at a uniform position.

  Then, at the initial stage of tilting of the operation member 23, a large operating force due to the biasing force (spring pressure) of the first elastic member 26a is applied to obtain a steep first change curve H1 shown in FIG. In the operation region of the operation member 23, the change in the biasing force (spring pressure) of the first elastic member 26a accompanying the forward movement of the operation member 25 in FIGS. The amount of displacement shown in FIG. 30 (in the graph in the operating region) due to the displacement of the rotational torque due to the length of the arm portion between the rotation center K and the point of application of the hook-like portion 25b to the bottom plate 11a gradually decreasing. A second change curve H2 having a constant inclination. In the coil spring which is the first elastic member 26a in the second change curve H2, the effective spring length is changed by the forward movement of the actuating member 25 and the winding portions formed at equal pitches are contracted. It is in a compressed state with no state.

  If the tilting operation is further continued, the step portion 23e is elastically moved through the receiving member 28 in addition to the compression of the first elastic member 26a as shown in FIG. The second elastic member 26b having a high force is compressed, and changes (changes) in the direction in which the displacement amount of the second curve H2 shown in FIG. 30 increases to become a third change curve H3. In the coil spring which is the second elastic member 26b in the third change curve H3, the effective spring length is changed by the forward movement of the actuating member 25 and the space between the winding portions formed at equal pitches is reduced. It is in a compressed state with no state. As described above, the operating force in the operating region of the operating member 23 includes the second curve H2 having a constant displacement due to the biasing force of the first elastic member 26a, and the displacement of the second curve H2 being the second. A third curve H3 that is variable in an increasing direction by the addition of the urging force of the elastic member 26b and a third curve H3 with a constant amount of displacement are obtained. Therefore, the operating force is the second and third change curves H2, H2. It changes greatly between H3.

  FIG. 36 and FIG. 37 are explanatory views showing a fourth other embodiment for obtaining the operating force of the operating member of the present invention. The fourth other embodiment will be described. It consists of coil springs having different pitches between the winding parts. For example, this coil spring has a gradually increasing pitch from the upper part toward the intermediate part, and the pitch of the lower part following the intermediate part is the pitch of the intermediate part It is formed with a larger pitch.

  Then, at the initial stage of tilting of the operation member 23 shown in FIG. 36A, a large operating force due to the urging force (spring pressure) of the return means 26 is applied, resulting in a steep first change curve H1 shown in FIG. In the operation region of the operation member 23, the change of the urging force (spring pressure) of the return means 26 accompanying the forward movement of the operation member 25 and the rotation of the operation member 23 are continued. The amount of displacement shown in FIG. 30 (the slope of the graph in the operating region) due to the displacement of the rotational torque due to the gradual shortening of the length of the arm portion from the center K to the point of application of the flange 25b to the bottom plate 11a. The second change curve H2 is constant. The coil spring which is the return means 26 in the second change curve H2 is in a state where the effective spring length does not change due to the forward movement of the actuating member 25 and the winding portions formed at different pitches are contracted. It is in a compressed state.

  When the tilting operation is further continued, as shown in FIGS. 36B to 36C, from the predetermined tilting angle of the operation member 23, the winding portion located at the uppermost portion sequentially overlaps with the next winding portion. Thus, the displacement amount of the second curve H2 shown in FIG. 30 is changed (changed) in a direction in which the displacement amount suddenly increases to become a third change curve H3. The coil spring which is the return means 26 in the third change curve H3 gradually changes so that the winding portions are sequentially overlapped and the effective spring length is shortened by the forward movement of the operation member 25, As a result, the urging force (spring pressure) is increased to form the third change curve H3. As described above, the operating force in the operating region of the operating member 23 includes the second curve H2 having a constant displacement amount, and the third curve H3 that is variable in a direction in which the displacement amount of the second curve H2 suddenly increases. Thus, the displacement becomes a third curve H3 having a constant displacement, and therefore the operating force greatly changes between the second and third change curves H2 and H3.

  Still further, when the tilting operation is continued, in FIGS. 36C to 36D, there is no overlap between the winding portions, and the effective spring length does not change, and the lower side biasing force (spring pressure) causes the first shown in FIG. The fourth change curve H4 can be obtained by changing (changing) the displacement amount of the third change curve H3 to be light. As a result, the amount of displacement of the operating force of the operating member 23 is variable. Needless to say, various modified configurations can be applied in addition to the configuration of the coil spring of the above embodiment.

The tip end portion of the rear side shaft portion 24b that is thinned and is not subjected to the upward biasing force by the return means 26 is reduced to reduce the roundness of the shaft support portion 24, and corresponds to the rear side shaft portion 24b. The arcuate portion of the second guide inner surface 21b is made smaller to reduce the size of the hole portion 21.
