  However, in the composite operation device described in Patent Document 1, since the contact pattern is formed on the substrate, there is a problem that the structure of the substrate tends to be complicated. On the other hand, according to the composite operation device described in Patent Document 2, it is not necessary to form a contact pattern on the substrate, so that the structure of the substrate can be simply formed. However, in the composite operation device described in Patent Document 2, since the rotary switch is incorporated in the operation knob, there is a problem that the structure of the operation knob is likely to be complicated and the assembling workability is deteriorated. .

  An object of the present invention is to provide a composite operation device capable of simply forming the structure of a substrate and an operation member.

Means for Solving the Problems and Effects of the Invention

  In order to solve the above problems, the present invention provides an operation member in which a dial knob and a rotor have the same central axis and are coupled so as to operate integrally, and a reference that is fixed to the substrate and orthogonal to the substrate. A holder having a cylindrical hole penetrating in the axial direction and a spherical outer peripheral portion, a hollow spherical main body portion slidably supported on the outer peripheral portion of the holder, and integrally formed with the main body portion A hollow cylindrical shaft portion having the central axis as an axis, the dial knob and the rotor being rotatable about the central axis at the shaft portion, and the dial knob and the rotor together with the shaft portion A non-contact type rotation detection sensor for detecting a rotation amount and a rotation direction of the rotor around the central axis is fixed to the substrate. And a rocking detection sensor for detecting a rocking direction around the rocking fulcrum of the base is fixed, the rocking fulcrum of the base is on the reference axis, and the reference axis and the central axis Is set to a position where the maximum approach amount when the rotor is closest to the rotation detection sensor in the direction orthogonal to the reference axis from the original position of the rotor is equal to or less than a set amount. And

  In this composite operating device, a contactless rotation detection sensor for detecting the rotation amount and rotation direction around the central axis of the rotor is fixed to the substrate. For this reason, it is not necessary to form a contact pattern on the substrate, so that the structure of the substrate can be simply formed. In addition, since it is not necessary to incorporate a rotation detection sensor in the operation member, the structure of the operation member can be simply formed.

  By the way, when the contactless rotation detection sensor is fixed to the substrate, it is necessary to take into account a change in the position of the rotor relative to the rotation detection sensor due to the swinging operation of the operation member. In other words, it is necessary to set the positional relationship between the rotor and the rotation detection sensor so that the rotor does not interfere with the rotation of the operation member. Moreover, it is necessary to set the positional relationship between the two so that the output value of the rotation detection sensor does not change. In the composite operating device of the present invention, when the rotor swings around the swing fulcrum of the base, the maximum approach amount when the rotor comes closest to the rotation detection sensor in the direction orthogonal to the reference axis from the original position is set. A base swing fulcrum is set at a position below the amount.

  For this reason, even if the rotor swings around the swing fulcrum of the base, the maximum approach amount with respect to the rotation detection sensor of the rotor is not more than the set amount, so that interference with the rotation detection sensor can be sufficiently avoided. It is.

  In carrying out the present invention, the rotation detection sensor may be arranged at a position where a maximum separation amount when the rotor is farthest from the original position in a direction parallel to the reference axis is not more than a set amount. Is possible. In this case, the rotation detection sensor is, for example, an infrared sensor having a light emitting portion and a light receiving portion arranged to face each other on the substrate, and with respect to the swing of the rotor around the swing fulcrum of the base, Infrared light from the light emitting part is transmitted through the uneven slit formed in the rotor and reaches the light receiving part, or an infrared light from the light emitting part is formed in the rotor. It is good to set so that the light-shielding state light-shielded by a slit may not be switched.

  According to this, even if the rotor swings around the swing fulcrum of the base, the maximum distance from the original position of the rotor in the direction parallel to the central axis is not more than the set amount. It is possible to satisfactorily prevent the value from changing.

  In carrying out the present invention, the operation member further includes a push knob incorporated in the shaft portion of the base so as to be slidable in the direction of the central axis, and the substrate has a push-motion in the direction of the central axis of the push knob. A push detection sensor for detecting the rotation is fixed, and the rocking fulcrum of the base is a position where the amount of displacement of the push knob in the direction of the central axis accompanying the rocking of the rotor from the original position is equal to or less than a set amount. It is also possible to set to. In this case, the push detection sensor is, for example, a mechanical switch that is always in contact with the push knob, and the contact is switched on and off in accordance with the push operation of the push knob. It is good to set so that the ON / OFF of the said contact may not switch with respect to rocking | fluctuation of the said push knob around.

  According to this, even when the rotor swings around the swing fulcrum of the base, the displacement amount of the push knob in the central axis direction is not more than the set amount, so that the output value of the push detection sensor is good to change. Can be prevented.

  In carrying out the present invention, a guide portion is integrally formed on the base, and the base is set in advance by the cooperation of the guide portion and a guide groove member provided on the substrate. It is also possible to swing in a predetermined direction.

  According to this, since the operation of the base is restricted by the guide portion and the guide groove member, the swing of the base can be accurately detected by the swing detection sensor.

  In this case, the guide groove member may be arranged outside the swing detection switch in a plan view. According to this, since the rocking detection switch is disposed closer to the rocking fulcrum of the base than the guide groove member, the rocking detection switch can be used even if there is a backlash between the guide portion and the guide groove member. In the vicinity of, the influence of the backlash is reduced, and the influence on the swing detection switch can be satisfactorily reduced.

  The guide portion 22e is fitted in the guide groove 23a of the guide groove member 23 provided upright on the substrate PCB. The guide groove 23a of the guide groove member 23 allows sliding of the left and right engagement protrusions 22e2 around the horizontal axis H1 in the guide portion 22e (see FIG. 7D) and vertically slides around the horizontal axis H2. It has a groove width that allows movement, and has an engagement hole 23a1 that engages with the upper engagement protrusion 22e1 of the guide portion 22e at the upper portion and restricts the upward movement of the arm portion 22c. (Refer FIG.7 (b)).

  When the base 22 swings around the horizontal axis H2 by the cooperation of the guide portion 22e and the guide groove member 23, one of the pair of arms 22c arranged symmetrically at an interval of 180 ° shown in FIG. (The left arm 22c in FIG. 3) is displaced upward (see FIG. 7B and FIG. 10), and the other (right arm 22c in FIG. 3) swings so as to be displaced downward (FIG. 7 ( c) and FIG. 10). At this time, another pair of arms 22c rotate about the horizontal axis H2 so that the central axis L1 of the base 22 swings from the reference axis L0 by a predetermined inclination angle θ (see FIG. 7D).

  The case 31 is made of, for example, ABS resin or PC / ABS resin, and is fixed to the substrate PCB with a screw (see FIGS. 3 and 4). The case 31 has a concave spherical base holding portion 31a that is always in contact with the main body portion 22a of the base 22 on the back surface thereof. In a state where the case 31 is fixed to the substrate PCB, the main body portion 22a of the base 22 is sandwiched between the base pressing portion 31a and the outer peripheral portion 21a of the holder 21, and the main body portion 22a of the base 22 is held by the outer peripheral portion 21a of the holder 21. It is blocked from leaving.

  The dial knob 11 is made of, for example, ABS resin, is formed in a double hollow cylindrical shape having an outer cylindrical portion 11a and an inner stepped cylindrical portion 11b, and is formed on the inner stepped cylindrical portion 11b. The annular groove 11b1 is supported by the outer cylindrical portion 22b1 of the shaft portion 22b of the base 22 so as to be rotatable about the central axis L1 (see FIGS. 3 and 4). The outer cylindrical portion 11a functions as a gripping portion that can be rotated by an operator with a finger. The inner cylindrical portion 11 b has a plurality of claw portions in the circumferential direction, and is integrated with the rotor 12 by engagement of each claw portion and the engagement hole portion of the rotor 12.

  The rotor 12 is made of, for example, POM resin or ABS resin, and can rotate around the central axis L1 with respect to the shaft portion 22b in the space between the outer cylindrical portion 22b1 and the inner cylindrical portion 22b2 of the shaft portion 22b in the base 22. And it is incorporated so as to be able to swing together with the shaft portion 22b (see FIGS. 3 and 4). The rotor 12 is prevented from being pulled upward by the claw engagement of the shaft portion 22b of the base 22 with the outer cylindrical portion 22b1.

  A concavo-convex portion 12a is formed in the central portion of the outer peripheral surface of the rotor 12 in the circumferential direction, and a leaf spring 14 (for example, made of stainless steel or spring phosphor bronze) incorporated in the shaft portion 22b of the base 22 It is urged elastically (see FIGS. 1 and 2) to give a feeling of moderation (click feeling) to the operator when the rotor 12 rotates about the central axis L1. An uneven slit 12 b is formed in the lower end portion of the rotor 12 in the circumferential direction. The uneven slit 12b functions to transmit or block infrared light from a photo interrupter 43 described later.

  The push knob 13 is made of, for example, colorless and transparent PMMA resin or PC resin, and is incorporated in the inner cylindrical portion 22b2 of the shaft portion 22b of the base 22, and includes a disk-shaped top wall portion 13a and the ceiling wall portion 13a. A plate-like shaft portion 13b that is integrally formed with the wall portion 13a and extends below the central axis L1 is provided (see FIGS. 3 and 4). The top wall portion 13a of the push knob 13 is subjected to a coating process and then laser-cut so that only a predetermined character portion becomes transparent, and is illuminated by a light emitting diode (not shown) provided on the substrate PCB. ing.

  The shaft portion 13b of the push knob 13 has a rail portion extending in the central axis direction L1 (longitudinal direction) at both side portions thereof, and is formed in the rail portion and an inner cylindrical portion 22b2 of the shaft portion 22b in the base 22. By being engaged with the rail groove, the base 22 can be slid in the central axis direction L1. The shaft portion 13b is always urged upward by a spring (not shown) provided between the shaft portion 22b of the base 22 and the inner cylindrical portion 22b2, but by the claw engagement with the inner cylindrical portion 22b2. Further, the escape from the inner cylindrical portion 22b2 is prevented.

  A switch push-down portion 13 c is formed at the lower end of the shaft portion 13 b of the push knob 13. The switch push-down portion 13c is always in contact with the tact switch 41, and when the push knob 13 is not pushed, the contact position between the switch push-down portion 13c and the tact switch 41 is the swing fulcrum O of the base 22. It is set to almost coincide with the position of.

  The top wall 13 a of the push knob 13 is accommodated in an annular dial bezel 15. The dial bezel 15 is, for example, a decorative member whose surface of ABS resin is plated, and is attached to the upper portion of the dial knob 11 by claw engagement (see FIGS. 1 and 3).

  A bezel 16 is provided between the dial knob 11 and the case 31 (see FIGS. 1 and 3). The bezel 16 is, for example, a decorative member whose surface of ABS resin is plated, and is attached to the case 31 by claw engagement. Further, a collar 17 is provided between the outer cylindrical portion 11a of the dial knob 11 and the outer cylindrical portion 22b1 of the base 22 (see FIGS. 1 and 3). The collar 17 serves to prevent the leaf spring 14 from being seen through the gap between the dial knob 11 and the bezel 16, and is formed of, for example, ABS resin and is attached to the outer cylindrical portion 22b1 of the base 22 by claw engagement. ing.

  The tact switch 41 (pushing detection sensor) is provided at a position where the reference axis L0 intersects at the center of the substrate PCB (see FIGS. 6 and 8). The tact switch 41 is a mechanical switch that switches on and off of the contact. The contact is turned on by the downward displacement of the switch pressing portion 13c accompanying the pushing operation of the push knob 13, and the contact is turned on by the upward displacement of the switch pressing portion 13c. Turn off. The push detection sensor is not limited to a mechanical switch such as the tact switch 41, and various position detection sensors such as an infrared sensor, a magnetic sensor, a capacitance sensor, and a pressure sensor can be used. In this case, on / off is determined by program processing by a CPU (not shown) or determination processing by a control circuit based on the amount of change in the output value of the sensor.

  The tact switch 42 (swing detection sensor) is provided corresponding to the switch push-down portion 22d of each arm portion 22c in the base 22 (see FIGS. 6 and 8). Similarly to the tact switch 41, each tact switch 42 is a mechanical switch in which the contact is switched on and off, and the contact is turned on by the downward displacement of each switch push-down portion 22d accompanying the swinging operation of the base 22, and the switch push-down portion 22d The contact is turned off by the upward displacement. The swing detection sensor is not limited to a mechanical switch such as each tact switch 42, and various position detection sensors can be used as in the case of the push detection sensor.

  A pair of photo interrupters 43 (rotation detection sensors) are provided at the outer peripheral position of the rotor 12 (substantially point symmetrical with the tact switch 41 as a center). (See FIGS. 6 and 8). Each photo interrupter 43 is, for example, an infrared sensor having a light emitting unit 43a and a light receiving unit 43b. The light emitting portion 43a and the light receiving portion 43b are arranged to face each other, and the concave and convex slit 12b of the rotor 12 passes between the light emitting portion 43a and the light receiving portion 43b, and infrared light that passes through the slit 12b. The rotation direction and amount of rotation of the rotor 12 are determined based on the pulse signal corresponding to the infrared light shielded by the slit 12b.

  In the present embodiment configured as described above, the contactless photo interrupter 43 that detects the rotation amount and the rotation direction of the rotor 12 around the central axis is fixed to the substrate PCB. Therefore, it is not necessary to form a contact pattern on the substrate PCB, so that the structure of the substrate PCB can be formed simply. Further, since it is not necessary to incorporate a photo interrupter in the operation member 10, the structure of the operation member 10 can be simply formed.

  By the way, in this embodiment, the base rocking fulcrum O is on the reference axis L0, and the height position of the base rocking fulcrum O with respect to the substrate PCB is the light emitting portion 43a of each photo interrupter 43. The height is set substantially the same as the infrared light detection position in the light receiving portion 43b (see FIG. 4). That is, when the rotor 12 swings around the swing fulcrum O of the base 22 as shown in FIG. 9, the rotor 12 is orthogonal to the reference axis L0 from the original position as shown by a two-dot chain line or a broken line in FIG. The base oscillating fulcrum O is set at a position where the maximum approach amount D2 when approaching each photo interrupter 43 in the horizontal direction is equal to or less than the set amount D1. Here, the set amount D1 represents the distance between the slit portion 12b of the rotor 12 and the light emitting portion 43a or the light receiving portion 43b when the rotor 12 is in the original position.

  As a result, even if the rotor 12 swings around the swing fulcrum O of the base 22 and the central axis L1 of the rotor 12 rotates by the predetermined inclination angle θ from the reference axis L0, each photo of the slit 12b in the rotor 12 is obtained. Since the maximum approach amount D2 with respect to the interrupter 43 is equal to or less than the set amount D1, it is possible to sufficiently avoid interference with each photo interrupter 43.

  In this embodiment, each photo interrupter 43 is disposed within a predetermined distance from the reference axis L0. That is, when the rotor 12 swings around the swing fulcrum O of the base 22 as shown in FIG. 9, the rotor 12 moves from the original position to the reference axis L0 as shown by a two-dot chain line or a broken line in FIG. Each photo interrupter 43 is arranged at a position where the maximum separation amount D4 when separated most in the parallel direction is equal to or less than the set amount D3. Here, the set amount D3 is a transmission state in which the infrared light from the light emitting portion 43a passes through the slit 12b of the rotor 12 and reaches the light receiving portion 43b even when the rotor 12 is displaced in a direction parallel to the reference axis L0. Alternatively, the distance is set such that the light shielding state where the infrared light from the light emitting portion 43a is shielded by the slit 12b is not switched.

  As a result, even if the rotor 12 swings around the swing fulcrum O of the base 22 and the central axis L1 of the rotor 12 rotates by a predetermined inclination angle θ from the reference axis L0, the rotor 12 is in a direction parallel to the reference axis L0. Since the maximum distance D4 from the original position of the rotor 12 is equal to or less than the set amount D3, it is possible to favorably prevent the output value of each photo interrupter 43 from changing.

  In this embodiment, the swing fulcrum O of the base 22 is set at a position where the amount of displacement of the push knob 13 in the central axis direction L1 accompanying the swing of the rotor 12 from the original position is substantially zero. That is, as shown in FIGS. 9 and 10, the swing support point O of the base 22 is switched on and off of the contact of the tact switch 41 with respect to the swing of the push knob 13 around the swing support point O of the base 22. It is set not to.

  As a result, even if the rotor 12 swings around the swing support point O of the base 22, the amount of displacement of the push knob 13 in the direction of the central axis L1 becomes substantially zero, so that the output value of the tact switch 41 changes. It can prevent well.

  In this embodiment, a guide portion 22e is integrally formed with the arm portion 22c of the base 22, and the base 22 is formed by the cooperation of the guide portion 22e and the guide groove member 23 provided on the substrate PCB. It can swing around the horizontal axis H1 or H2.

  As a result, the operation of the base 22 is regulated by the guide portion 22e and the guide groove member 23, so that the swing of the base 22 can be accurately detected by the tact switch 42.

  Further, each guide portion 22e and the guide groove member 23 are disposed outside each tact switch 42 in plan view. Thereby, since each tact switch 42 is arranged on the side closer to the swing fulcrum O of the base 22 than each guide groove member 23, even if there is rattling between the guide portion 23 e and the guide groove member 23, In the vicinity of each tact switch 42, the influence of the backlash amount is reduced, and the influence on each tact switch 42 can be satisfactorily reduced.

(Modified embodiment)
In the above embodiment, the base 22 is configured to swing around the horizontal axis H1 or H2 to detect the swinging operation in four directions. However, the present invention is not limited to this. For example, the base 22 includes the horizontal axes H1 and H2. It may be configured to swing around any one of the axes and detect only the swing operation in two directions.

  In the above-described embodiment, the position at which the displacement amount of the push knob 13 in the central axis direction L1 due to the swinging of the rotor 12 from the original position is almost zero is set as the swinging fulcrum O of the base 22. The swing fulcrum O of the base 22 is displaced in the central axis direction L1 within a range of a set amount or less in which the contact of the tact switch 41 is not switched on and off with respect to the swing of the push knob 13 around the swing fulcrum O.
