Definitions
- the present invention relates to a multi-operational input device which is capable of carrying out a predetermined input operation with two different press and rotation operations, and more particularly, to a multi-operational input device which mounts a press detecting element and a rotation detecting element on a common circuit board.
- a pair of plungers is slidably held in the operating body, respectively, through a coil spring, and front tips of these plungers protrude from an external edge of the operating body and engage with concavity and convexity formed at an inner peripheral surface of the case.
- a shaft is provided in the center of the operating body, and a cylindrical portion is provided outside of the shaft.
- the code plate is spline-connected to the shaft of the center through the return spring. Accordingly, even though the code plate rotates integrally with the operating body, the code plate does not move vertically while the operating body moves vertically.
- the rotation detecting element is made up of photo interrupters that are mounted inside of the circuit board.
- the press detecting element is made up of separate photo interrupters mounted outside of the circuit board, when the cylindrical portion moves down along with the pressing operation of the operating body, a light path of the photo interrupter is blocked so that an on-signal is output.
- the code plate rotates integrally with the operating body. Therefore, on/off signals are alternately output from the photo interrupters (rotation detecting element) mounted inside on the circuit board, and the operator can detect rotation operation performed by the operator on the basis of these signals.
- the photo interrupters rotation detecting element mounted inside on the circuit board
- the operator can detect rotation operation performed by the operator on the basis of these signals.
- a front end of a plunger is disengaged from the uneven portion of an inner peripheral surface of the case so as to generate a click feeling; therefore, the operator can perceive the rotation amount of the operating body by the click feeling.
- the cylindrical portion blocks a light path of a separate photo interrupter (press detecting element) which is mounted outside of the circuit board when the operating body has moved by a predetermined stroke. Therefore, the output from the photo interrupter is converted from ON to OFF, and pressing of the operating body can be detected by the converted signals.
- the code plate does not move while the operating body moves downward, signals from the photo interrupter (rotation detecting element) inside the circuit board are not converted.
- the cylindrical portion is deviated from the light path of the outside photo interrupter (press detecting element). Accordingly, the output from the photo interrupter is converted from OFF to ON, and moving of the operating body can be detected on the basis of the converted signal.
- the entire input device including the circuit board should be made large in a transverse direction; therefore, it is difficult to make the device small in the transverse direction.
- the above-mentioned problem is not limited to an input device in which the photo interrupter is used both in the rotation detecting element and the press detecting element.
- the problem is also found in an input device, in which a push switch is used as the press detecting element, and a photo interrupter is used as the rotation detecting element.
- the front end of the plunger which protrudes from an outer edge of the operating body is pressure-contacted with the uneven portion of the inner peripheral surface of the case, and the rotation of the operating body makes the plunger disengaged from the uneven portion so as to generate a click feeling. Therefore, the input device is inevitably made large in the transverse direction by the aforementioned click mechanism, and thus it is difficult to make the device small in the transverse direction.
- the present invention has been finalized in view of the inherent drawbacks in the related art, and it is an object of the present invention to provide a multi-operational input device which can be made small in the transverse direction.
- a multi-operational input device includes a press operating member which is supported by a supporting body so as to be press-operated; a circuit board which is disposed in a press-operating direction of the press operating member; a press detecting element which is mounted on the front surface of the circuit board and operated by pressing the press operating member; a rotation operating member which is supported by the supporting body so as to be rotatably operated; and a rotation detecting element which is mounted on the circuit board and operated by rotating the rotating operating member.
- the rotation detecting element is mounted on the rear surface of the circuit board, and a part of the rotation operating member is allocated at the front side of the circuit board, and a rotating force of the rotation operating member applied from the front side of the circuit board is transmitted to the rear side of the circuit board.
- a mounting space of the press detecting elements overlaps with one side of the circuit board, and the rotation detecting elements overlaps with the other side of the circuit board. Accordingly, it is possible to make the entire input device small in a transverse direction.
- the rotation operating member is preferably a barrel-shaped rotation ring which surrounds the circuit board. Accordingly, it is possible to make the multi-operational input device small in a lengthwise direction.
- the supporting body includes an upper knob and a lower knob which hold the rotation ring therebetween, and the circuit board and the upper knob are fixed onto an upper end of a support shaft which is erected at the center of the lower knob. Accordingly, it is possible to improve operability by adjacently disposing the press knob and the rotation ring.
- rotation detecting elements may be used, such as a hall element, a rotary encoder or he like.
- the rotation detecting element includes photo interrupters, in which a light emitting element and a light receiving element are disposed to face each other with a concave portion interposed therebetween.
- a code plate having the light shielding portion and the light transmitting portion is fixed onto an inner peripheral surface of the rotation ring, and the light shielding portion and the light transmitting portion move inside the concave portion in conjunction with the rotation of the rotation ring.
- the click mechanism can be disposed in a space under the circuit board. Therefore, it is possible to make the entire input device small in the transverse direction by the click mechanism, and to prevent rattling of the rotation ring by using the urging force of the plunger provided in the click mechanism.

Further, since the click plate 32 and the code plate 33 are locked in the inner peripheral surface of the rotation ring 27 and fixed therein, the click plate 32 and the code plate 33 can integrally rotate in conjunction with the rotation of the rotation ring 27. At this time, the plunger 31 is pressure-contacted with the bottom surface of the click plate 32 by a resilient force of the coil spring 30.

- only one of the two push switches 37 involves in a converting operation of a contact, and the other push switch 37 is used as a resilience applying means which urges upward the press knob 29 in fine balance.

- the light path between the light emitting element 22b and the light receiving element 22c of the photo interrupter 22 is not blocked, and thus all of the photo interrupters 22 output high-level signals.
- the convex portions 11b and the notch portions 18a which face each other in the first and second directions, are denoted as follows for convenience: 11b-1 for the convex portion and 18a-1 for the notch portion in the X1 direction; 11b-2 for the convex portion and 18a-2 for the notch portion in the X2 direction; 11b-3 for the convex portion and 18a-3 for the notch portion in the Y1 direction; 11b-4 for the convex portion and 18a-4 for the notch portion in the Y2 direction, as shown in Fig. 11 , in a non-operating state, the convex portions 11b-1, 2, 3, 4 face the entrances of the notch portions 18a-1, 2, 3, 4.
- the engaging protrusion 11 moves in, for example, the X1 direction from the neutral position, as shown in Fig. 12A , the front ends of the convex portions 11b-3 and 11b-4 are guided by the facing inner wall surfaces of the aperture 18; the convex portion 11b-1 intrudes into the notch portion 18a-1; and the engaging protrusion 11 is prevented from moving in the X1 direction more than a position where the outer wall surface of the engaging protrusion 11 located in the X1 direction is in contact with the inner wall surface of the aperture 18.
- the engaging protrusion 11 are restricted within the aperture 18 by three parts, that is, the convex portions 11b-1, 11b-3, and 11b-4; therefore, the operating body 2 moving in the X1 direction is prevented from moving in either the Y1 or Y2 direction by mistakes.

- the front ends of the convex portions 11b-1 and 11b-2 slide on the facing inner wall surfaces of the aperture 18, and the convex portion 11b-3 intrudes into the notch portion 18a-3; therefore, the engaging protrusion 11 is prevented from moving in the Y1 direction more than a location where the outer wall surface of the engaging protrusion 11 located in the Y1 direction is in contact with the inner wall surface of the aperture 18.
- the engaging protrusion 11 are restricted within the aperture 18 by three parts, that is, the convex portions 11b-1, 11b-2, and 11b-3; therefore, the operating body 2 moving in the Y1 direction is prevented from moving in either the X1 or X2 direction by mistakes.
- the engaging protrusion 11 moves in either the first or second direction within the aperture 18 in conjunction with the rocking operation of the operating body 2, either the first or second slider 19 or 20 slides while being guided by the guide member 16, and then one of the photo interrupters 22 is turned on selectively.

- the arm portion 19b is guided by the first guide protrusion 16b of the guide member 16, and the first slider 19 moves in the X1 direction; therefore, the light shielding portion 19c moves in the recessed portion 22a of the photo interrupter 22 located in the X1 direction.
- the photo interrupter 22 outputs a low-level signal.
- the second slider 20 since the second slider 20 does not receive an external force through the engaging protrusion 11 so as to remain in the neutral position, the signals output from the rest three photo interrupters located in the Y1-Y2 direction and the X2 direction are maintained at a high-level.
- the engaging protrusion 11 moves in the X2 direction from the neutral position, and, in this case, the first slider 19 receives an external force through the engaging protrusion 11 so as to move in the X2 direction; therefore, the photo interrupter 22 located in the X2 direction outputs a low-level signal, and the signals output from the rest three photo interrupters 22 remain at a high-level.
- the engaging protrusion 11 moves in the Y1 direction from the neutral position shown in Fig. 8 , since the engaging protrusion 11 relatively moves only within the elongated hole 19d elongated in the second direction (Y1-Y2 direction), the first slider 19 does not receive an external force through the engaging protrusion 11 so as to remain in the neutral position.
- the second slider 20 receives an external force through the engaging protrusion 11 so as to move in the Y1 direction.
- the arm portion 20b is guided by the second guide protrusion 16c of the guide member 16, and the second slider 20 moves in the Y1 direction; therefore, the light shielding portion 20c moves in the recessed portion 22a of the photo interrupter 22 located in the Y1 direction.

- the signals output from the rest three photo interrupters 22 located in the X1-X2 direction and the Y2 direction are maintained at a high-level.
- the operating body 2 is selectively operated to rock in either of the first and second directions, which are perpendicular to each other, since only the signal output from the photo interrupter 22 located in the operating direction is changed from high-level to low-level, it is possible to identify the operating direction of the operating body 2 on the basis of the signals output from the four photo interrupters 22. Meanwhile, when the rocking-operating force on the operating body 2 is removed, the lower end of the driving rod 13 receives the resilient force of the coil spring 12 so as to return to the center of the inner bottom surface of the cam groove 14; therefore, the entire operating body 2 including the holder 7 stands upright, and the engaging protrusion 11 or the first and second sliders 19 and 20 return to the neutral position automatically.
- the components of the operating body 2 such as the base 25, the lower knob 26, the rotation ring 27, the upper knob 28, the press knob 29, protrude from the upper cover 4 of the chassis 1, and, if an operator rotates the rotation ring 27 clockwise or counter-clockwise, the click plate 32 and the code plate 33 are integrally rotated in conjunction with the rotation ring 27.

Description
- The present invention relates to a multi-operational input device which is capable of carrying out a predetermined input operation with two different press and rotation operations, and more particularly, to a multi-operational input device which mounts a press detecting element and a rotation detecting element on a common circuit board.
- In the related art, as an example of this type of multi-operational input device, there has been known a device in which an operating body is held in a case so as to be rotatable and vertically movable, a code plate is spline-connected to the operating body by a return spring, and a rotation detecting element which detects a rotation operation of the operating body and a press detection element which detects a pressing operation of the operating body are mounted on a circuit board disposed in the case (for example, see
JP-A-2004-87307 pages 4 to 5,Fig. 3 )). - A pair of plungers is slidably held in the operating body, respectively, through a coil spring, and front tips of these plungers protrude from an external edge of the operating body and engage with concavity and convexity formed at an inner peripheral surface of the case. A shaft is provided in the center of the operating body, and a cylindrical portion is provided outside of the shaft. The code plate is spline-connected to the shaft of the center through the return spring. Accordingly, even though the code plate rotates integrally with the operating body, the code plate does not move vertically while the operating body moves vertically. The rotation detecting element is made up of photo interrupters that are mounted inside of the circuit board. When the code plate rotates along with the rotation operation of the operating body, an on-signal and an off-signal are alternately output from the photo interrupters along with the rotation of the code plate. In addition, the press detecting element is made up of separate photo interrupters mounted outside of the circuit board, when the cylindrical portion moves down along with the pressing operation of the operating body, a light path of the photo interrupter is blocked so that an on-signal is output.
- In the multi-operational input device configured in this way, when an operator rotates the operating body, the code plate rotates integrally with the operating body. Therefore, on/off signals are alternately output from the photo interrupters (rotation detecting element) mounted inside on the circuit board, and the operator can detect rotation operation performed by the operator on the basis of these signals. In addition, when the operating body is rotated, a front end of a plunger is disengaged from the uneven portion of an inner peripheral surface of the case so as to generate a click feeling; therefore, the operator can perceive the rotation amount of the operating body by the click feeling.
- In the meantime, when the operator presses the operating body, the operating body moves downward while pressing against the return spring, the cylindrical portion blocks a light path of a separate photo interrupter (press detecting element) which is mounted outside of the circuit board when the operating body has moved by a predetermined stroke. Therefore, the output from the photo interrupter is converted from ON to OFF, and pressing of the operating body can be detected by the converted signals. However, since the code plate does not move while the operating body moves downward, signals from the photo interrupter (rotation detecting element) inside the circuit board are not converted. Further, when pressing force applied to the operating body is removed, the operating body moves to an initial position by a resilient force of the return spring, the cylindrical portion is deviated from the light path of the outside photo interrupter (press detecting element). Accordingly, the output from the photo interrupter is converted from OFF to ON, and moving of the operating body can be detected on the basis of the converted signal.
- However, in the multi-operational input device according to the related art, since a mounting space of the rotation detecting element and a mounting space of the press detecting element are concentrated on the surface of the circuit board, the entire input device including the circuit board should be made large in a transverse direction; therefore, it is difficult to make the device small in the transverse direction. In addition, the above-mentioned problem is not limited to an input device in which the photo interrupter is used both in the rotation detecting element and the press detecting element. For example, the problem is also found in an input device, in which a push switch is used as the press detecting element, and a photo interrupter is used as the rotation detecting element.
- In addition, in the multi-operational input device according to the related art, the front end of the plunger which protrudes from an outer edge of the operating body is pressure-contacted with the uneven portion of the inner peripheral surface of the case, and the rotation of the operating body makes the plunger disengaged from the uneven portion so as to generate a click feeling. Therefore, the input device is inevitably made large in the transverse direction by the aforementioned click mechanism, and thus it is difficult to make the device small in the transverse direction.
- The present invention has been finalized in view of the inherent drawbacks in the related art, and it is an object of the present invention to provide a multi-operational input device which can be made small in the transverse direction.
- In order to solve the above-described problems, according to an aspect of the invention, a multi-operational input device includes a press operating member which is supported by a supporting body so as to be press-operated; a circuit board which is disposed in a press-operating direction of the press operating member; a press detecting element which is mounted on the front surface of the circuit board and operated by pressing the press operating member; a rotation operating member which is supported by the supporting body so as to be rotatably operated; and a rotation detecting element which is mounted on the circuit board and operated by rotating the rotating operating member. In this case, the rotation detecting element is mounted on the rear surface of the circuit board, and a part of the rotation operating member is allocated at the front side of the circuit board, and a rotating force of the rotation operating member applied from the front side of the circuit board is transmitted to the rear side of the circuit board.
- In the multi-operational input device with this structure, a mounting space of the press detecting elements overlaps with one side of the circuit board, and the rotation detecting elements overlaps with the other side of the circuit board. Accordingly, it is possible to make the entire input device small in a transverse direction.
- With this structure, even though the entire rotation operating member may be disposed on the surface of the circuit board, the rotation operating member is preferably a barrel-shaped rotation ring which surrounds the circuit board. Accordingly, it is possible to make the multi-operational input device small in a lengthwise direction.
- In this case, the supporting body includes an upper knob and a lower knob which hold the rotation ring therebetween, and the circuit board and the upper knob are fixed onto an upper end of a support shaft which is erected at the center of the lower knob. Accordingly, it is possible to improve operability by adjacently disposing the press knob and the rotation ring.
- In addition, with the above structure, rotation detecting elements may be used, such as a hall element, a rotary encoder or he like. However, preferably, the rotation detecting element includes photo interrupters, in which a light emitting element and a light receiving element are disposed to face each other with a concave portion interposed therebetween. Further, a code plate having the light shielding portion and the light transmitting portion is fixed onto an inner peripheral surface of the rotation ring, and the light shielding portion and the light transmitting portion move inside the concave portion in conjunction with the rotation of the rotation ring.
- In this case, an uneven portion is formed on the rear side of the code plate, and a plunger, which is elastically urged toward the code plate, is held by the lower knob so as to move vertically, and the rotation of the rotation ring makes an upper end of the
plunger 31 disengaged from the uneven portion, so as to generate a click feeling. Accordingly, the click mechanism can be disposed in a space under the circuit board. Therefore, it is possible to make the entire input device small in the transverse direction by the click mechanism, and to prevent rattling of the rotation ring by using the urging force of the plunger provided in the click mechanism. -

circular ring body 6 is disposed inside thecase 3, a pair ofspindles 6a and a pair of through-holes 6b are alternately formed at every 90-degree interval. Bothspindles 6a are inserted intoshaft holes 3a formed at upper inner walls of thecase 3 facing each other, and thering body 6 is rotatably held in thecase 3 about a line connecting bothshaft holes 3a as the central axis.

Thepin 8 is prevented from falling off thering body 6 by anengaging ring 9, and theholder 7 is rotatably held in thering body 6 about an axis line connecting both through-holes 6b as the central axis. That is, theholder 7 is rotatably supported so as to rock in a direction orthogonal to thecase 3 through thering body 6. In the following description, a rocking direction (X1-X2 direction) of theholder 7 which rocks about bothspindles 6 of thering body 6 as a fulcrum is referred to as a first direction, a rocking direction (Y1-Y2 direction) of theholder 7 which rocks about thepin 8 as a fulcrum is referred to as a second direction. - The
holder 7 forms some constituent parts of the operatingbody 2, a pair ofprotrusions 7d is disposed to be erected on a top surface of theholder 7 with ascrew hole 7c interposed between the pair, and aconnection body 10 is integrated with a lower end of theholder 7 by using a fixed means, such as snap-fitting. In addition, in the present embodiment, even though theconnection body 10 is used for a driving motor or the like to be accommodated in theholder 7. However, when such a space for accommodation is unnecessary, theholder 7 and theconnection body 10 may be formed of an integrated molding. A barrel-shaped engagingprotrusion 11 is protrudingly disposed at the center of a bottom surface of theconnection body 10, and anaccommodation hole 11a is formed in the engagingprotrusion 11 so as to extend vertically (SeeFig. 10 ). Fourconvex portions 11b are protrudingly disposed at an outer wall surface of the engagingprotrusion 11 so as to serve as guided portions, and theseconvex portions 11b extend in first and second directions from the center of each side of a square. As shown inFig. 7 , acoil spring 12 and a drivingrod 13 are inserted into theaccommodation hole 11a of the engagingprotrusion 11, a leading end (bottom end) of the drivingrod 13 is pressure-contacted with an inner bottom surface of acam groove 14 by resilient force of thecoil spring 12. Thecam groove 14 is a conical dented portion formed on a top surface of asupport body 15 made of synthetic resin material, and aclick protrusion 14a is formed along the same periphery about the innermost of the dented portion. Thesupport body 15 is pressure-fixed in aconcave portion 5a which is formed in the center of the inner bottom surface of thelower cover 5, and four upper corners of thesupport body 15 are provided withprotrusions 15a and screwholes 15b formed thereon. - A
guide member 16 made of synthetic resin is disposed on thesupport body 15, and fourcircular holes 16a are formed on four corners of theguide member 16. Two of thecircular holes 16a function as a positioning hole so as to be engaged with theprotrusions 15a of thesupport body 15, and ascrew 17 is inserted through the rest twocircular holes 16a and further inserted into the screw holes 15b. Thus, theguide member 16 is fixed on thesupport body 15.

Fournotch portions 18a are formed at an inner wall surface of theaperture 18 so as to function as guide portions, and these notch portions extend in first and second directions toward the outside from the center of each side of a square. Eachconvex portion 11b of the engagingprotrusion 11 faces the entrance of eachnotch portion 18a. When a length between opposite inner wall surfaces of theaperture 18 is set to L1, and a length between oppositeconvex portions 11b is set to L2, L2 is set to be slightly shorter than L1. - In addition, a pair of

Accordingly, thefirst slider 19 is slidably supported by both of thefirst guide protrusions 16b that are shorter sides of theguide member 16. In the meantime, thesecond slider 20 is disposed in an opposite direction in which thelight shielding portion 20c protrudes downward from the plate surface of thearm portion 20b, and as thearm portion 20b is held between the correspondingsecond guide protrusions 16c, whereby thesecond slider 20 is slidably supported by both of thesecond guide protrusions 16c that are the longer sides of theguide member 16. In this way, since thefirst slider 19 and thesecond slider 20 are disposed in a state opposite to each other to form the laminated arrangement, both of thelight shielding portions 19c of thefirst slider 19 and both of the shieldingportions 20c of thesecond slider 20 are positioned on the same plane, and theelongated hole 19d formed in theframe 19a of thefirst slider 19 overlaps with theelongated hole 20d formed in theframe 20a of thesecond slider 20 in a state orthogonal to each other. The aforementioned engagingprotrusion 11 is inserted through both of theelongated holes Fig. 8 ). When thefirst slider 19 is pressed by an external force from the engagingprotrusion 11 and moves in the first direction (X1-X2 direction), thesecond slider 20 does not move because the engagingprotrusion 11 relatively moves only inside theelongated hole 20d. When thesecond slider 20 is pressed by an external force from the engagingprotrusion 11 and moves in the second direction (Y1-Y2 direction), thefirst slider 19 does not move because the engagingprotrusion 11 relatively moves only inside theelongated hole 19d. - A printed
board 21 is fixed on thelower cover 5, and theguide member 16 is exposed through anaperture 21a formed in a central portion of the printedboard 21. Fourphoto interrupters 22 are mounted on the printedboard 21, and eachphoto interrupter 22 is disposed in X1-X2 and Y1-Y2 directions on the printedboard 21. Thephoto interrupter 22 is a light detecting element in which alight emitting element 22b and alight receiving element 22c are disposed to face each other and integrated with each other with a recessedportion 22a interposed therebetween. As shown inFig. 8 , when thefirst slider 19 and thesecond slider 20 are in neutral positions in the first and second directions, eachlight shielding portion portion 22a of eachphoto interrupter 22. - As shown in
Figs. 1 to 5 , acircular aperture 4a is formed in a central portion of theupper cover 4, and a plurality ofoperation keys 23 is provided around theaperture 4a. A plurality of push switches (not shown) is disposed inside theupper cover 4 so as to correspond to eachoperation key 23, and these push switches are operated when theoperation keys 23 are pressed. In addition, acircular decoration ring 24 is fitted and fixed to theaperture 4a of theupper cover 4 by a fixation means, such as a snap-in relationship, and the components of the operatingbody 2, such as abase 25, alower knob 26, arotation ring 27, anupper knob 28, and apress knob 29, protrude from thedecoration ring 24. - The
base 25 is disposed on theaforementioned holder 7, a throughhole 25a and a pair ofpositioning holes 25b are formed in thebase 25, and thesepositioning holes 25b are engaged with both of theprotrusions 7d of theholder 7. Thelower knob 26 is disposed on thebase 25, and acylindrical support shaft 26a is disposed in a central portion of thelower knob 26 so as to be erected thereon. In addition, a pair ofaccommodation holes 26b is disposed in thelower knob 26, other portions of thelower knob 26 than the accommodation holes 26b and thesupport shaft 26a are vertically hollow. Coil springs 30 andplungers 31 are inserted into both of theaccommodation holes 26b, respectively, and theseplungers 31 are pressure-contacted with the bottom surface of aclick plate 32 by the resilient force of the coil springs 30. Anuneven portion 32a is formed in a circumferential direction on the bottom surface of theclick plate 32, and fourengaging portions 32b are protrudingly formed at an outer periphery of theclick plate 32 at every 90-degree interval. Each engagingportion 32b is locked in and fixed to anotch portion 27a formed at a lower end of an inner peripheral surface of therotation ring 27, and acode plate 33 is fixed onto theclick plate 32 byscrews 34. A plurality oflight shielding portions 33a and a plurality of light transmittingportions 33b are alternately formed in a circumferential direction, and acircuit board 35 is disposed on thecode plate 33. - As shown in
Figs. 13 to 15 , twophoto interrupters 36, serving as rotation detecting elements, are mounted on the rear side of thecircuit board 35, and a pair of push switches 37, serving as press detecting elements, is mounted on the surface of thecircuit board 35. Thephoto interrupter 35 is a light detecting elements in which a light emitting element (not shown) and a light receiving element (not shown) are disposed to face each other and integrated with each other with aconcave portion 36a interposed therebetween, and thelight shielding portion 33a and thelight transmitting portion 33b of thecode plate 33 are designed to move inside theconcave portion 36a of thephoto interrupter 36. In addition, thepush switch 37 is called a tack switch having astem 37a, thestem 37a is urged upward by a resilient force of a tact spring (not shown) built therein. Further, a pair of throughholes 35b is formed in thecircuit board 35 with an ovalengaging hole 35a interposed therebetween, and theengaging hole 35a is engaged with an upper end of thesupport shaft 26a of thelower knob 26. Further, although not shown, a wiring pattern is formed on thecircuit board 35 to allow current to flow to thephoto interrupters 36 and the push switches 37, and a lead wire connected to the wiring pattern is connected to the aforementioned printedboard 21 through a central hole of thecode plate 33 or theclick plate 32 and a hollow portion of thelower knob 26. - The
upper knob 28 is disposed on thecircuit board 35, arecess 28a is formed on the top surface of theupper knob 28. A throughhole 28b is formed in the center of an inner bottom surface of therecess 28a, afixation screw 38 inserted into the throughhole 28b is inserted into thescrew hole 7c of theholder 7 through thesupport shaft 26a of thelower knob 26 and the throughhole 25a of thebase 25. Accordingly, thelower knob 26 is fixed above theholder 7 with the base 25 interposed therebetween, and thecircuit board 35 and theupper knob 28 are fixed on an upper end of thesupport shaft 26a which is disposed to be erected on thelower knob 26, and therotation ring 27 is held between thelower knob 26 and theupper knob 28. That is, therotation ring 27, serving as a rotation operation member, is rotatably supported between thelower knob 26 and theupper knob 28 which forms a supporting body, and therotation ring 27 is continuously disposed over a range from the top surface of thecircuit board 35 to the rear side thereof. Further, since theclick plate 32 and thecode plate 33 are locked in the inner peripheral surface of therotation ring 27 and fixed therein, theclick plate 32 and thecode plate 33 can integrally rotate in conjunction with the rotation of therotation ring 27. At this time, theplunger 31 is pressure-contacted with the bottom surface of theclick plate 32 by a resilient force of thecoil spring 30. Furthermore, since a pressing force of theplunger 31 is applied upward to therotation ring 27 through theclick plate 32, therotation ring 27 is held between thelower knob 26 and theupper knob 28 without rattling. In addition, a pair ofrelief holes 28c and a pair ofguide holes 28d are formed in the inner bottom surface of therecess 28a of theupper knob 28 with the throughhole 28b interposed therebetween, both of the push switches 37 mounted on the top surface of thecircuit board 35 are exposed through therelief holes 28c to protrude inside therecess 28a. Further, guidepieces 28e are formed to theupper knob 28 to extend downward from outer edges of both of theguide holes 28d, and theseguide pieces 28e are inserted through the throughholes 35b of thecircuit board 35 to reach thelower knob 26. - The
press knob 29, serving as a press operation member, is disposed in therecess 28a of theupper knob 28 so as to move vertically. As a pair ofprotrusions 29a formed on the bottom surface of thepress knob 29 are brought in contact with thestem 37a of the push switches 37, respectively, thepress knob 29 is urged upward by a resilient force of the tact switch built in both of the push switches 37. In addition, only one of the two push switches 37 involves in a converting operation of a contact, and the other push switch 37 is used as a resilience applying means which urges upward thepress knob 29 in fine balance. Since a plurality ofhooks 29a is formed on an edge of a lower end of thepress knob 29, and by locking thesehooks 29a in an outer edge of therecess 28a so as to be fixed therein, thepress knob 29 is prevented from falling off from theupper knob 28. In addition, a pair ofguide rods 29b is suspended from thepress knob 29, and theseguide rods 29b reach the inside of theguide pieces 28e through the guide holes 28d of theupper knob 28. - Hereinafter, the operation of a multi-directional input device and the multi-operational input device, both of which are provided in the control unit constructed as described above, will be described.
- First, the operation of the multi-directional input device will be described.
Figs. 1 ,3 and4 show a non-operating state, in which an external force is not applied to theoperating body 2; therefore, the components of the operatingbody 2, such as theholder 7, thebase 25, thelower knob 26, therotation ring 27, and theupper knob 28, stand vertically (in Z1-Z2 direction inFig. 1 ). In the non-operating state, the lower end of the drivingrod 13 is pressure-contacted with the center (innermost portion) of the inner bottom surface of thecam groove 14 by the resilient force of thecoil spring 12. Further, as shown inFig. 11 , the engagingprotrusion 11 which holds the drivingrod 13 is located in the center of theaperture 18 of theguide member 16. In addition, as shown inFig. 8 , since the engagingprotrusion 11 is located at the center of theelongated holes second sliders light shielding portions recesses 22a of thephoto interrupters 22. As a result, the light path between the light emittingelement 22b and thelight receiving element 22c of thephoto interrupter 22 is not blocked, and thus all of thephoto interrupters 22 output high-level signals. - When an operator rocks the operating
body 2 in either first or second direction from the above non-operating state, since theholder 7 rocks in the above direction with the supporting points at eitherspindles 6a or thepin 8 of thering body 6, the lower end of the drivingrod 13 held by the engagingprotrusion 11 slides outward from the center at the inner bottom surface of thecam groove 14, and a click feeling generated when the drivingrod 13 surmounts theclick protrusion 14a is fed back to the operator through the operatingbody 2. At this time, the engagingprotrusion 11 moves outward in either first or second direction from the center of theaperture 18, and then the engagingprotrusion 11 is prevented from moving further when oneconvex portion 11b intrudes into and engages with thecorresponding notch portion 18a. - That is, when the
convex portions 11b and thenotch portions 18a, which face each other in the first and second directions, are denoted as follows for convenience: 11b-1 for the convex portion and 18a-1 for the notch portion in the X1 direction; 11b-2 for the convex portion and 18a-2 for the notch portion in the X2 direction; 11b-3 for the convex portion and 18a-3 for the notch portion in the Y1 direction; 11b-4 for the convex portion and 18a-4 for the notch portion in the Y2 direction, as shown inFig. 11 , in a non-operating state, theconvex portions 11b-1, 2, 3, 4 face the entrances of thenotch portions 18a-1, 2, 3, 4. If the engagingprotrusion 11 moves in, for example, the X1 direction from the neutral position, as shown inFig. 12A , the front ends of theconvex portions 11b-3 and 11b-4 are guided by the facing inner wall surfaces of theaperture 18; theconvex portion 11b-1 intrudes into thenotch portion 18a-1; and the engagingprotrusion 11 is prevented from moving in the X1 direction more than a position where the outer wall surface of the engagingprotrusion 11 located in the X1 direction is in contact with the inner wall surface of theaperture 18. Therefore, at the limited moving positions, the engagingprotrusion 11 are restricted within theaperture 18 by three parts, that is, theconvex portions 11b-1, 11b-3, and 11b-4; therefore, the operatingbody 2 moving in the X1 direction is prevented from moving in either the Y1 or Y2 direction by mistakes. Likewise, if the engagingprotrusion 11 moves in, for example, the Y1 direction, as shown inFig. 12B , the front ends of theconvex portions 11b-1 and 11b-2 slide on the facing inner wall surfaces of theaperture 18, and theconvex portion 11b-3 intrudes into thenotch portion 18a-3; therefore, the engagingprotrusion 11 is prevented from moving in the Y1 direction more than a location where the outer wall surface of the engagingprotrusion 11 located in the Y1 direction is in contact with the inner wall surface of theaperture 18. In this case, at the limited moving positions, the engagingprotrusion 11 are restricted within theaperture 18 by three parts, that is, theconvex portions 11b-1, 11b-2, and 11b-3; therefore, the operatingbody 2 moving in the Y1 direction is prevented from moving in either the X1 or X2 direction by mistakes. - In addition, if the engaging
protrusion 11 moves in either the first or second direction within theaperture 18 in conjunction with the rocking operation of the operatingbody 2, either the first orsecond slider guide member 16, and then one of thephoto interrupters 22 is turned on selectively. For example, when the engagingprotrusion 11 moves in the X1 direction from the neutral position shown inFig. 8 , since the engagingprotrusion 11 moves only within theelongated hole 20d elongated in the first direction (X1-X2 direction), thesecond slider 20 does not receive an external force (a driving force in the moving direction) through the engagingprotrusion 11 so as to remain in the neutral position. However, thefirst slider 19 receives an external force through the engagingprotrusion 11 so as to move in the X1 direction. In this case, thearm portion 19b is guided by thefirst guide protrusion 16b of theguide member 16, and thefirst slider 19 moves in the X1 direction; therefore, thelight shielding portion 19c moves in the recessedportion 22a of thephoto interrupter 22 located in the X1 direction. Furthermore, when the engagingprotrusion 11 reaches the limited moving position in the X1 direction, since the light path between the light emittingelement 22b and thelight receiving element 22c of thephoto interrupter 22 is blocked by thelight shielding portion 19c, thephoto interrupter 22 outputs a low-level signal. At this time, since thesecond slider 20 does not receive an external force through the engagingprotrusion 11 so as to remain in the neutral position, the signals output from the rest three photo interrupters located in the Y1-Y2 direction and the X2 direction are maintained at a high-level. The same operation can be found when the engagingprotrusion 11 moves in the X2 direction from the neutral position, and, in this case, thefirst slider 19 receives an external force through the engagingprotrusion 11 so as to move in the X2 direction; therefore, thephoto interrupter 22 located in the X2 direction outputs a low-level signal, and the signals output from the rest threephoto interrupters 22 remain at a high-level. - On the other hand, if the engaging
protrusion 11 moves in the Y1 direction from the neutral position shown inFig. 8 , since the engagingprotrusion 11 relatively moves only within theelongated hole 19d elongated in the second direction (Y1-Y2 direction), thefirst slider 19 does not receive an external force through the engagingprotrusion 11 so as to remain in the neutral position. However, thesecond slider 20 receives an external force through the engagingprotrusion 11 so as to move in the Y1 direction. In this case, thearm portion 20b is guided by thesecond guide protrusion 16c of theguide member 16, and thesecond slider 20 moves in the Y1 direction; therefore, thelight shielding portion 20c moves in the recessedportion 22a of thephoto interrupter 22 located in the Y1 direction. In addition, when the engagingprotrusion 11 reaches the limited moving position in the Y1 direction, since the light path between the light emittingelement 22b and thelight receiving element 22c of thephoto interrupter 22 is blocked by thelight shielding portion 20c, thephoto interrupter 22 outputs a low-level signal. At this time, since thefirst slider 19 does not receive an external force through the engagingprotrusion 11 so as to remain in the neutral position, the signals output from the rest threephoto interrupters 22 located in the X1-X2 direction and the Y2 direction are maintained at a high-level. The same operation can be found when the engagingprotrusion 11 moves in the Y2 direction from the neutral position, and, in this case, thesecond slider 20 receives an external force through the engagingprotrusion 11 so as to move in the Y2 direction; therefore, thephoto interrupter 22 located in the Y2 direction outputs a low-level signal, and the signals output from the rest threephoto interrupters 22 remain at a high-level. - If the
operating body 2 is selectively operated to rock in either of the first and second directions, which are perpendicular to each other, since only the signal output from thephoto interrupter 22 located in the operating direction is changed from high-level to low-level, it is possible to identify the operating direction of the operatingbody 2 on the basis of the signals output from the fourphoto interrupters 22. Meanwhile, when the rocking-operating force on theoperating body 2 is removed, the lower end of the drivingrod 13 receives the resilient force of thecoil spring 12 so as to return to the center of the inner bottom surface of thecam groove 14; therefore, theentire operating body 2 including theholder 7 stands upright, and the engagingprotrusion 11 or the first andsecond sliders - Hereinafter, the operation of the multi-operational input device will be described with reference to
Figs. 3 to 5 . As shown inFigs. 3 and4 , the components of the operatingbody 2, such as thebase 25, thelower knob 26, therotation ring 27, theupper knob 28, thepress knob 29, protrude from theupper cover 4 of thechassis 1, and, if an operator rotates therotation ring 27 clockwise or counter-clockwise, theclick plate 32 and thecode plate 33 are integrally rotated in conjunction with therotation ring 27. In addition, since thelight shielding portion 33a and thelight transmitting portion 33b rotate in theconcave portion 36a of eachphoto interrupter 36, mounted on the rear surface of thecircuit board 35, in conjunction with the rotation of thecode plate 33, thephoto interrupter 36 outputs pulse signals corresponding to the rotation of thecode plate 33. - In addition, since the rotation of the
click plate 32 makes the upper ends of theplungers 31, which are elastically urged by the coil springs 30, disengaged from theuneven portion 32a, a click feeling generated at this time is fed back to the operator through the operatingbody 2. In this way, if therotation ring 27 is rotatably operated, since thephoto interrupter 36 outputs signals corresponding to the rotating direction and the amount of the rotation of therotation ring 27, it is possible to obtain the information on the rotation of therotation ring 27 along with click feelings on the basis of the signals. - On the other hand, if the operator presses the
press knob 29 downward (Z2 direction inFig. 1 ), since the stems 37a of the push switches 37 mounted on the top surface of thecircuit plate 35 are pressed down by theprotrusions 29a of thepress knob 29, the contacts of the push switches 37 are switched to ON from OFF. In addition, if such pressing force is removed, thepress knob 29 returns to the original position by the resilient force of the tact spring built in the push switches 37, and the contacts of the push switches 37 are also converted to OFF from ON. At this time, since theguide rods 29b suspended from the bottom surface of thepress knob 29 are guided by theguide pieces 28e of theupper knob 28 and move vertically, thepress knob 29 can be press-operated smoothly without rattling. - As described above, the multi-operational input device according to the embodiment includes the
press knob 29 supported on the top surface of theupper knob 28 so as to be press-operated, thecircuit board 35 disposed in a press-operating direction of thepress knob 29, apush switch 37 mounted on the front surface of thecircuit board 35, therotation ring 27 which is supported between thelower knob 26 and theupper knob 28 so as to be rotatably operated, thecode plate 33 which rotates in conjunction with therotation ring 27, and thephoto interrupters 36 mounted on the rear surface of thecircuit board 35. With this structure, since the push switches 37 mounted on the front surface of thecircuit board 35 are operated by pressing thepress knob 29, and thecode plate 33 is rotated in conjunction with the rotation of therotation ring 27, thephoto interrupters 36 mounted on the rear surface of thecircuit board 35 are operated. Therefore, a mounting space of the push switches 37, serving as press detecting elements, overlaps with one side of thecircuit board 35, and a mounting space of thephoto interrupters 36, serving as rotation detecting elements, overlaps with the other side of thecircuit board 35. Accordingly, it is possible to make the entire input device small in a transverse direction. Moreover, therotation ring 27, serving as the rotation operating member, is continuously disposed over a range from the front side of thecircuit board 35 to the rear side thereof, and the rotating force of therotation ring 27 received at the front side of thecircuit board 35 is transmitted to the rear side of thecircuit board 35. Therefore, thepress knob 29 and therotation ring 27 can be arranged close to each other in the front side of thecircuit board 35, and thus the operator can easily press-operate thepress knob 29 and rotatably operate therotation ring 27. - In addition, the
uneven portion 32a is formed on the bottom surface of theclick plate 32 which integrally rotates with thecode plate 33, theplungers 31 are held in the accommodation holes 26b of thelower knob 26 through the coil springs 30 so as to move vertically, and the rotation of therotation ring 27 makes the upper ends of theplungers 31 disengaged from theuneven portion 32a, so as to generate a click feeling. Therefore, a space under thecircuit board 35 can be effectively used to dispose a click mechanism. In this respect, it is possible to make the entire input device small in the transverse direction. Moreover, since an upward pressing force applied to theuneven portion 32a through theplunger 31 is also applied to therotation ring 27 through theclick plate 32, therotation ring 27 can be reliably prevented from rattling by using the pressing force through theplunger 31 provided in the click mechanism. - In addition, even though the embodiment describes the input device, in which the
push switch 37 is used as the press detecting element mounted on the surface of thecircuit board 35, any press detecting element may be used as the press detecting element as long as it is operated by pressing thepress knob 29 serving as the press operating member. For example, a magnetic detecting element and an optical detecting element or the like may be used as the press detecting element. - Further, even though the embodiment describes the input device, in which the
code plate 33 is integrated with theclick plate 32 and theuneven portions 32a is formed on the bottom surface of theclick plate 32, an uneven portion may be formed on the bottom surface of thecode plate 33 and theclick plate 32 may be omitted. - Furthermore, even though the embodiment describes the control unit including both of the multi-directional input device and the multi-operational input device, the invention may be applied to a control unit including only the multi-operational input device.
- In the multi-operational input device of the invention, the pressing detecting element is mounted on the surface of the circuit board and the rotation detecting element is mounted on the rear side of the circuit board, and at least some portion of the rotation operating member is disposed on the surface of the circuit board, and the rotating force of the rotation operating member applied from the surface of the circuit board is transmitted to the rear side of the circuit board. Therefore, the mounting space of the press detecting elements overlaps with one side of the circuit board, and the rotation detecting elements overlaps with the other side of the circuit board. Accordingly, it is possible to make the entire input device small in the transverse direction.
