  If the inner shaft member is rotatably incorporated in the hollow portion of the rotatable outer shaft member as in the prior art described above, the two shaft members can be selectively rotated. Although it is possible to realize a compact rotary operation type electric component that can be operated, the user must change the outer shaft member and the inner shaft member when performing two types of rotation operations in succession, so that the operability is good It was hard to say. In addition, in this prior art, the hollow portion of the outer shaft member is difficult to use as a light guide path, and it is difficult to provide an illumination area on the front surface of the inner shaft member. . Furthermore, in this prior art, even if there is a space for providing a display portion for characters, symbols, etc. on the front surface of the inner shaft member, when the inner shaft member is rotated, the display portion is also rotated to impair the design. Therefore, after all, there is a restriction that it is difficult to use the front surface of the inner shaft member as a display space.

  The present invention has been made in view of the actual situation of the prior art as described above, and its purpose is to perform two types of rotation operation, which is excellent in operability and easy to secure an illumination area and a display space. It is to provide a mold electrical component.

  In order to achieve the above object, in the rotary operation type electrical component of the present invention, a housing having a cylindrical guide wall, and a rotationally extrapolated to the guide wall so as to be relatively forward along the axial direction. A hollow drive shaft capable of reciprocating between the first operation position and the second operation position on the back side, an elastic member that constantly urges the hollow drive shaft toward the first operation position, and the hollow drive A first rotating member and a second rotating member which can be engaged with and disengaged from the shaft; a first rotation detecting means for detecting the rotation of the first rotating member; and a first detecting unit for detecting the rotation of the second rotating member. Rotation detecting means, and the hollow drive shaft can be moved from the first operation position to the second operation position by a pressing operation force against the elastic member, and the first rotation member is When the hollow drive shaft is held in the first operating position The second rotary member engages with the hollow drive shaft and is integrally rotatable, and the second rotary member engages with the hollow drive shaft when the hollow drive shaft is held at the second operating position. The configuration is such that it can rotate integrally.

  In the rotary operation type electric component configured as described above, the hollow drive shaft is in the first operation position and engaged with the first rotation member when no pressing operation force is applied. When the drive shaft is rotated, the first rotating member rotates integrally, so that a signal corresponding to the rotating operation can be taken out from the first rotation detecting means. Further, when the hollow drive shaft at the first operation position is moved to the second operation position by a pressing operation force against the elastic member, the engagement between the hollow drive shaft and the first rotation member is released, 2 Since the hollow drive shaft that has reached the operation position engages with the second rotating member, when the hollow drive shaft is rotated in this pressed state (ie, the hollow drive shaft is pushed and rotated), the second rotating member is integrated. Thus, a signal corresponding to the rotation operation can be taken out from the second rotation detecting means. When the pressing operation force on the hollow drive shaft is removed, the hollow drive shaft is automatically returned to the first operation position by being urged by the elastic member, so that the engagement between the hollow drive shaft and the second rotating member is released. Is done.

  That is, in the rotary operation type electrical component as described above, the hollow drive shaft can be selectively disposed at two types of rotary operation positions, the first operation position and the second operation position, and independent rotation detection at each operation position. Therefore, when performing two types of rotation operations in succession, the user does not have to change the operation member (such as a hollow drive shaft or a knob attached to the drive shaft), and the operability is improved. Is greatly improved. Further, since the hollow drive shaft is extrapolated to the cylindrical guide wall, the first and second rotating members, the first and second rotation detecting means, the elastic members, etc. are all radially outward of the guide walls. Therefore, it is easy to use the space (hollow part) on the radially inner side of the guide wall as a light guide or to arrange another part such as a push switch in the hollow part. It becomes easy to secure an area and a display space.

  In the above configuration, when the second rotating member has a self-return function by providing a return spring that automatically returns the second rotating member to the neutral position in the rotation direction, the second rotating member is engaged with the second rotating member. Since the hollow drive shaft is also pushed back to the neutral position before the rotation operation, it is preferable that the hollow drive shaft is easily re-engaged with the first rotation member when the hollow drive shaft is pushed back to the first operation position by the elastic member.

  In this case, the housing has an opening in which the guide wall is loosely inserted, the first case in which the first rotating member is disposed around the opening, and a guide wall protruding from the periphery of the guide wall. A second case in which the second rotating member and the return spring are arranged, and an opening into which the guide wall is loosely inserted, and is interposed between the first and second cases and around the opening. If the first and second cases and the intermediate case are integrated with each other, the structure of each case can be simplified and the assembly work can be simplified. Therefore, it is preferable. Furthermore, a spring receiving projection that can lock the end of the return spring is provided on the inner bottom of the second case, and a notch portion is provided on the second rotating member to avoid interference with the spring receiving projection. If the end of the return spring is separated from the spring receiving projection by the rotational operation force on the second rotation member, the return spring is placed after the second rotation member is disposed in the second case during assembly. Since it can be easily assembled, the assemblability can be further improved.

  In the above configuration, the first rotating member is provided with a plurality of engaging portions that can be engaged with and disengaged from the hollow drive shaft by being shifted by a predetermined angle in the circumferential direction, and in the second case. Is provided with a stopper portion that restricts the allowable rotation amount of the second rotating member to a smaller angle than the predetermined angle, and the pusher that has been rotated while holding the hollow drive shaft in the second operating position. When the operating force is removed, the hollow drive shaft that has returned to the first operating position can be more reliably engaged with the first rotating member.

  In the above configuration, when the hollow drive shaft is provided with a spring member that is engaged with and disengaged from a part of the hollow drive shaft while moving from the first operation position to the second operation position, the hollow drive shaft is hollow. Since the forward / backward movement of the drive shaft (reciprocating motion along the axial direction) can be clearly felt, the operability can be further improved.

  The rotary operation type electrical component of the present invention can selectively arrange the hollow drive shaft at two types of rotary operation positions, ie, the first operation position and the second operation position, and independent rotation detection at each operation position. Because it is possible to do so, the user does not have to change the operating member (hollow drive shaft or knob attached to the drive shaft, etc.) when performing two types of rotation operations in succession. Is greatly improved. Further, since the hollow drive shaft is extrapolated to the cylindrical guide wall, the first and second rotating members, the first and second rotation detecting means, the elastic members, etc. are all radially outward of the guide walls. Therefore, it is easy to use the space (hollow part) on the radially inner side of the guide wall as a light guide or to arrange another part such as a push switch in the hollow part. It becomes easy to secure an area and a display space.

The cases 1 to 3 have the same outer diameter, are overlapped in a state of being positioned with respect to each other, and a plurality of leg pieces 4a extending from the mounting plate 4 disposed on the front surface of the first case 1 are provided in the second case. Each case 1-3 is integrated by caulking to the back surface of 2. A contact pattern 5 is disposed on the annular inner bottom of the first case 1, and a terminal 6 led out from the contact pattern 5 extends to the outside of the case 1. A first rotating member 7 having a slider 8 attached to the back surface is rotatably incorporated in the space in the first case 1 covered with the mounting plate 4, and the rotating member A ring-shaped click spring 9 that is elastically contacted with the front surface of 7 is incorporated. Similarly, the contact pattern 10 is disposed on the annular inner bottom of the second case 2, and the terminal 11 led out from the contact pattern 10 extends to the outside of the case 2. In addition, in the space in the second case 2 covered by the intermediate case 3, a second rotating member 13 having a slider 12 attached to the back surface is rotatably incorporated, and the rotating member A return spring 14 for urging 13 against a rotational operation force is incorporated. A hollow drive shaft 15 that can selectively engage with the first and second rotating members 7 and 13 is extrapolated to the guide wall 2a so as to be rotatable and reciprocally movable along the axial direction. A coil spring 16 is incorporated between the spring receiving portion 15 c of the hollow drive shaft 15 and the spring receiving portion 3 e of the intermediate case 3.

  The structure of the rotary operation type electrical component will be described in detail. The first case 1 is formed in an annular shape having an opening 1a into which the guide wall 2a is loosely inserted. An annular wall 1b is formed. Engagement step portions 1c are formed at a plurality of locations on the outer peripheral surface of the annular wall 1b, and the leg pieces 4a of the mounting plate 4 are fitted into the engagement step portions 1c. The contact pattern 5 (see FIG. 6) for the rotary encoder exposed at the inner bottom portion of the first case 1 and the terminal 6 led out from the contact pattern 5 are integrated with the first case 1 by insert molding. It is formed. In addition, an opening 4b into which the guide wall 2a is loosely inserted is formed at the center of the mounting plate 4.

  The first rotating member 7 incorporated in the first case 1 is formed in a ring shape. A click groove 7a is formed on the entire front surface of the first rotating member 7, and the click spring 9 is engaged with and disengages from the click groove 7a as the rotating member 7 rotates, thereby generating a click feeling. It is like that. Further, the slider 8 attached to the back surface side of the first rotating member 7 is in sliding contact with the contact pattern 5 so that a pulse signal is output from the terminal 6 as the rotating member 7 rotates. The contact pattern 5 and the slider 8 constitute a first rotation detecting means. Engagement projections 7 b projecting inward are formed at a plurality of locations (for example, four locations) on the inner peripheral portion of the first rotation member 7, and these engagement projections 7 b are formed on the hollow drive shaft 15. The engaging recess 15b can be engaged and disengaged. In addition, each engagement convex part 7b is shifted by a predetermined angle in the circumferential direction and formed at equal intervals, and when there are four engagement convex parts 7b as shown in the figure, they are shifted by 90 degrees and dispersedly arranged.

  The hollow drive shaft 15 is formed in a cylindrical shape with a slightly larger diameter on the rear side, and this hollow drive shaft 15 is slidably fitted on the guide wall 2a and passes through the opening 1a of the first case 1. ing. A small-diameter portion of the hollow drive shaft 15 projects forward from the opening 4b of the mounting plate 4, and a plurality of locking holes 15a for attaching an operation knob 24 described later are formed in the small-diameter portion. Engagement recesses 15 b that can be engaged with and disengaged from the engagement projections 7 b of the first rotating member 7 are formed at a plurality of locations on the outer peripheral edge of the large-diameter portion of the hollow drive shaft 15. Further, on the back side of the hollow drive shaft 15, there are a number of engagements that can be engaged with and disengaged from a spring receiving portion 15 c into which the front end portion of the coil spring 16 is inserted and a sawtooth portion 13 d of the second rotating member 13. A toothed portion 15d (see FIG. 8) is formed. As shown in FIG. 2, the hollow drive shaft 15 is held at a position (first operation position) sandwiched between the coil spring 16 and the mounting plate 4 during non-operation, and at this time, the engagement recess 15 b is in the first position. Is engaged with the engaging projection 7b of the rotating member 7. When the hollow drive shaft 15 in the first operation position is pressed against the coil spring 16 in the axial direction, as shown in FIG. 3, the hollow drive shaft 15 is an engaging portion. The tooth portion 15d can be moved to a position (second operation position) where the tooth portion 15d engages with a sawtooth portion 13d (more precisely, a concave portion of the sawtooth portion 13d) that is an engaging portion of the second rotating member 13.

  The intermediate case 3 is formed in an annular shape having an opening 3a into which the guide wall 2a is loosely inserted. An annular wall 3b is formed on the outer peripheral edge of the intermediate case 3, and positioning pins 3c are formed to project at two locations on the front surface of the annular wall 3b. The front surface of the annular wall 3b is a surface that overlaps the back surface of the first case 1, and positioning cases 3 and 3 are positioned by inserting positioning pins 3c into positioning holes (not shown) formed on the back surface. Engagement step portions 3d are formed at a plurality of locations on the outer peripheral surface of the annular wall 3b, and the leg pieces 4a of the mounting plate 4 are fitted into the engagement step portions 3d. A spring receiving portion 3 e into which the rear end portion of the coil spring 16 is inserted is formed on the inner peripheral edge portion of the intermediate case 3.

  A guide wall 2a penetrating each opening 1a, 3a, 4b is formed in the center of the second case 2, and is guided by the guide wall 2a to rotate and move the hollow drive shaft 15 forward and backward. (Reciprocation along the axial direction) is performed. An annular wall 2b is formed on the outer peripheral edge of the second case 2, and positioning pins 2c are formed to protrude at two locations on the front surface of the annular wall 2b. The front surface of the annular wall 2b is a surface that overlaps the back surface of the intermediate case 3, and the positioning pins 2c are inserted into positioning holes (not shown) formed in the back surface so that the cases 2 and 3 are positioned. Engagement step portions 2d are formed at a plurality of locations on the outer peripheral surface of the annular wall 2b, and the leg pieces 4a of the mounting plate 4 fitted into the engagement step portions 2d are caulked to the back surface of the second case 2. It has been. Further, a stopper portion 2e capable of contacting the drive wall 13c of the second rotating member 13 is formed on the inner peripheral surface of the annular wall 2b, and the allowable rotation amount of the second rotating member 13 is formed by the stopper portion 2e. Is restricted to an angle (for example, ± about 30 degrees) that is sufficiently smaller than the dispersion angle (for example, 90 degrees) of the engaging convex portion 7b. A pair of spring receiving projections 2 f are formed on the inner bottom of the second case 2. As shown in FIG. 11A, both ends of the return spring 14 are locked to the spring receiving projections 2f when not operated, but the return spring 14 is elastic as the second rotating member 13 rotates. Therefore, as shown in FIG. 11B, one end of the return spring 14 is detached from the spring receiving projection 2f. Note that a retaining protrusion 2g is formed on the inner peripheral surface of the guide wall 2a to prevent the operation body 22 described later from falling off. Further, the rotary switch contact pattern 10 (see FIG. 12) exposed at the inner bottom of the second case 2 and the terminal 11 led out from the contact pattern 10 are integrated with the second case 2 by insert molding. Is formed.

  The second rotating member 13 incorporated in the space in the second case 2 has a shape having a pair of cutout windows 13b and a pair of drive walls 13c around the cylindrical portion 13a (see FIGS. 9 and 10). Molded. At the front end of the cylindrical portion 13a, a serrated portion 13d that can be engaged with and disengaged from the engaging tooth portion 15d of the hollow drive shaft 15 is formed over the entire circumference. The return spring 14 is incorporated around the cylindrical portion 13a, and both end portions of the return spring 14 can be engaged with the drive wall 13c. Further, as shown in FIG. 11 (a), since the spring receiving projection 2f of the second case 2 passes through the notch window 13b, both ends of the return spring 14 can be locked by the spring receiving projection 2f. is there. And when the 2nd rotation member 13 rotates, either one drive wall 13c will push in the one end part of the return spring 14, and will be extended according to the rotation direction. However, when the second rotating member 13 rotates by a predetermined amount, the drive wall 13c comes into contact with the stopper portion 2e as shown in FIG. 11 (b), so that the second rotating member 13 cannot be rotated any further. As a result, the rotation angle of the second rotating member 13 is regulated. Further, the slider 12 attached to the back side of the second rotating member 13 is in sliding contact with the contact pattern 10, and an ON signal is output from the terminal 11 when the rotating member 13 rotates a predetermined amount. The contact pattern 10 and the slider 12 constitute second rotation detecting means.

  The rotary operation type electrical component configured as described above can be assembled in the following procedure. That is, first, after the second rotating member 13 is assembled in the space between the guide wall 2a and the annular wall 2b of the second case 2 and the spring receiving projection 2f is passed through the notch window 13b, the cylindrical portion Both end portions of the return spring 14 arranged around 13a are locked to the spring receiving projection 2f. Next, after positioning the intermediate case 3 on the second case 2 so as to cover the return spring 14 and the drive wall 13c, the coil spring 16 and the hollow drive shaft 15 are sequentially extrapolated to the guide wall 2a. The first case 1 is stacked on the intermediate case 3 and positioned. And after incorporating the 1st rotation member 7 and the click spring 9 in the 1st case 1 in order, the leg piece 4a of the mounting plate 4 laminated | stacked so that the 1st case 1 might be covered is engaged step part 1c, By fitting into 3d and 2d and fixing by caulking, the cases 1 to 3 are integrated to complete the assembly.

  Next, the operation of this rotary operation type electric component will be described. As shown in FIG. 2, the hollow drive shaft 15 is held at the first operation position when no pressing operation force is applied (during non-operation), and the engagement recess 15 b of the hollow drive shaft 15 is the first. Is engaged with the engaging projection 7b of the rotating member 7. Therefore, when the user rotates the hollow drive shaft 15 in this state, the first rotary member 7 rotates integrally and the contact position of the slider 8 with respect to the contact pattern 5 changes, so that the hollow drive shaft 15 The pulse signal of the rotary encoder corresponding to the rotation operation is output from the terminal 6.

  Further, as shown in FIG. 3, when the user presses the hollow drive shaft 15 in the first operation position against the coil spring 16 in the axial direction and moves it to the second operation position, the hollow drive shaft 15 is moved. The engagement between the shaft 15 and the first rotation member 7 is released, but the engagement tooth portion 15d of the hollow drive shaft 15 engages with the saw tooth portion 13d of the second rotation member 13 at the second operation position. Therefore, when the hollow drive shaft 15 is rotated against the return spring 14 in this pressed state (that is, when the hollow drive shaft 15 is pushed and turned), the second rotating member 13 rotates integrally and the contact pattern 10 is rotated. Since the contact position of the slider 12 with respect to changes, the ON signal of the rotary switch corresponding to the rotational operation of the hollow drive shaft 15 is output from the terminal 11.

  Since the drive wall 13c drives one end of the return spring 14 with the rotation of the second rotation member 13, as shown in FIG. 11B, the return spring 14 is detached from one spring receiving projection 2f. And elastically stretches. Further, when the operation force on the hollow drive shaft 15 is removed at the second operation position, the return spring 14 is elastically restored and pushes back the drive wall 13c, so that the second rotating member 13 reaches the initial position shown in FIG. Since the coil spring 16 is elastically restored and the hollow drive shaft 15 is pushed back to the first operating position, the hollow drive shaft 15 is disengaged from the second rotating member 13 and the first rotation again. Engage with member 7.

  Next, as a specific use example of the rotary operation type electric component described above, as shown in FIG. 4, the push switch 21 and its operating body 22 are arranged in a space (hollow part) on the radially inner side of the guide wall 2a. The composite operation type electrical component will be described. As shown in the figure, the composite operation type electrical component is mounted on a circuit board 20. A push switch 21 and an LED 23 are disposed on the circuit board 20, and a part of the operation body 22 made of a translucent resin material protrudes forward from the guide wall 2 a. The operating body 22 has a stem portion 22a mounted on the push switch 21 and is prevented from falling off the guide wall 2a by the retaining protrusion 2g. The spring always urges the operating body 22 forward. The thin portion 22b of the operating body 22 is opposed to the LED 23, and the front surface of the thin portion 22b is an illumination area. An operation knob 24 is attached to the front end portion of the hollow drive shaft 15, and this operation knob 24 is locked in the locking hole 15 a of the hollow drive shaft 15. The terminals 6 and 11 are soldered to a wiring pattern (not shown) provided on the circuit board 20.

  In the composite operation type electric component shown in FIG. 4, the operation knob 24 is integrated with the hollow drive shaft 15, so the user selects the first rotating member 7 and the second rotating member 13 via the operation knob 24. The user can perform a rotational operation manually, and the user can press the push switch 21 via the operation body 22. Furthermore, since the front surface of the thin portion 22b of the operating body 22 is an illuminated area, the visibility in the dark place is good, and characters, symbols, etc. are displayed on the front surface of the operating body 22 that does not rotate during operation. Even if it provides a part, it has the advantage that design nature is not spoiled.

  As described above, the rotary operation type electrical component according to the present embodiment can selectively arrange the hollow drive shaft 15 at two types of rotary operation positions, ie, the first operation position and the second operation position. Since independent rotation detection can be performed at the position, the user needs to change the operation member (for example, the operation knob 24 attached to the hollow drive shaft 15) when performing two types of rotation operations in succession. Eliminates the operability significantly. Further, since the hollow drive shaft 15 is extrapolated to the cylindrical guide wall 2a, all of the first and second rotating members 7, 13, the contact patterns 5, 10, the coil spring 16, the return spring 14, etc. It can arrange | position in the space of the radial direction outer side of the guide wall 2a. As a result, as shown in FIG. 4, it becomes easy to use the space (hollow part) in the radial direction of the guide wall 2a as a light guide path, or to dispose another part such as the push switch 21 in the hollow part, It is easy to secure an illumination area and a display space.

  Further, in the rotary operation type electrical component according to the present embodiment, the first case 1 in which the first rotation member 7 is disposed, and the guide wall 2a are provided so as to protrude from the second rotation member 13 and the return spring 14. Since the housing is constituted by the second case 2 in which the coil spring 16 is arranged and the intermediate case 3 that is interposed between the first and second cases 1 and 2 and in which the coil spring 16 is arranged, each case The structures 1 to 3 are simple and easy to mold, and the assembly work can be simplified. For example, the second rotating member 13 needs to be incorporated so as to be able to rotate against the elastic force of the return spring 14. When the rotary operation type electric component is assembled, the second rotating member 13 is incorporated in the second case 2. After the rotating member 13 is disposed, both end portions of the return spring 14 extrapolated to the cylindrical portion 13a only need to be engaged with the spring receiving projections 2f penetrating the notch window 13b, so that the second rotating member 13 and the return spring 14 can be easily incorporated.

  Further, in the rotary operation type electrical component according to the present embodiment, when the operating force on the hollow drive shaft 15 is removed at the second operation position, the return spring 14 automatically returns the second rotary member 13 to the position before the rotation operation. In addition, since the self-return mechanism in which the coil spring 16 pushes the hollow drive shaft 15 back to the first operation position is employed, the engagement recess 15b of the hollow drive shaft 15 that has returned from the second operation position to the first operation position. Is easily reengaged with the engaging convex portion 7 b of the first rotating member 7. In particular, in the present embodiment, the allowable rotation amount of the second rotating member 13 is restricted to an angle sufficiently smaller than the dispersion angle of the engaging convex portion 7b by the stopper portion 2e that can come into contact with the drive wall 13c. Therefore, when the pushing operation force that was rotating while holding the hollow drive shaft 15 in the second operation position is removed, the hollow drive shaft 15 that has returned to the first operation position is reliably rotated to the first position. The member 7 can be engaged.

  4 shows a usage example in which the push switch 21, the operating body 22 and the like are arranged in the space (hollow portion) on the radially inner side of the guide wall 2a, the usage method of the hollow portion can be appropriately selected. For example, by arranging a light guide or the like in the hollow portion, the front surface of the hollow portion can be used as a display-dedicated space (non-operating region) that also serves as an illumination region.

  Further, when a click line spring 17 as shown in FIG. 13 is added to the rotary operation type electric component according to this embodiment, the forward / backward movement (reciprocation along the axial direction) of the hollow drive shaft 15 is clearly felt. Therefore, the operability can be further improved. That is, the click line spring 17 is incorporated on the back side of the first case 1, for example, and the hollow drive shaft 15 is moved from the first operation position to the second operation position. If the protrusion or the like engages with the click line spring 17 to generate a click feeling, the user can clearly know that the hollow drive shaft 15 has moved to the second operation position by the click feeling transmitted to the finger. Therefore, erroneous operation can be prevented.
