Therefore, it is possible to detect both rotation and raising / lowering of the operating body and use it as a composite operation type electrical component. As a result, an excellent detection function can be ensured, and thinning of the composite operation type electrical component can be realized. Further, it is possible to prevent signals from being output from the rotation detection member during the raising and lowering of the mounting member, and to ensure stable signal output performance.

また、操作つまみ２０を回転軸２１に取り付けた状態では、図２，３に例示するように、第１つば部２３は操作つまみ２０の一側部を形成し、第２つば部２５は操作つまみ２０の他側部を形成する。操作つまみ２０と第１カム部材２２とは、後述するように所定の一方向のみに第１つば部２３を介して一体的に回転可能となっており、また、操作つまみ２０と第２カム部材２４は、後述するように所定の一方向とは逆方向のみに第２つば部２５を介して一体的に回転可能となっている。 When the operation knob 20 is attached to the rotary shaft 21, as illustrated in FIGS. 2 and 3, the first collar portion 23 forms one side of the operation knob 20, and the second collar portion 25 is the operation knob. 20 other side parts are formed. As will be described later, the operation knob 20 and the first cam member 22 are integrally rotatable in only one predetermined direction via the first collar portion 23, and the operation knob 20 and the second cam member are also rotatable. As will be described later, 24 can be rotated integrally through the second collar portion 25 only in a direction opposite to a predetermined one direction.

上述した第１ラチェット機構２７は、第１カム部材２２の回転方向を所定の一方向のみに、すなわち図１の矢印２６で示す方向に制限するものである。すなわち、操作つまみ２０を図１の矢印２６方向に回転させたときには、第１ラチェット機構２７、及び第１つば部２３を介して第１カム部材２２が矢印２６方向に回転する。しかし、矢印２６方向とは逆の方向である矢印２９方向に、操作つまみ２０を回転させたときには、第１ラチェット機構２７の内部に滑りを生じ、これに伴って第１ラチェットばね２８は縮み、第１カム部材２２は回転しない状態、すなわち静止状態に保たれる。 The first ratchet mechanism 27 described above restricts the rotation direction of the first cam member 22 to only one predetermined direction, that is, the direction indicated by the arrow 26 in FIG. That is, when the operation knob 20 is rotated in the direction of the arrow 26 in FIG. 1, the first cam member 22 rotates in the direction of the arrow 26 via the first ratchet mechanism 27 and the first flange portion 23. However, when the operation knob 20 is rotated in the direction of the arrow 29, which is the direction opposite to the direction of the arrow 26, the first ratchet mechanism 27 is slipped, causing the first ratchet spring 28 to contract, The first cam member 22 is kept in a non-rotating state, that is, a stationary state.

また、上述した第２ラチェット機構３０は、第２カム部材２４の回転方向を矢印２６で示す方向とは逆方向である矢印２９で示す方向のみに制限するものである。すなわち、操作つまみ２０を矢印２９方向に回転させたときには、第２ラチェット機構３０、及び第２つば部２５を介して第２カム部材２４が矢印２９方向に回転する。しかし、矢印２６方向に操作つまみ２０を回転させたときには、第２ラチェット機構３０の内部に滑りを生じ、これに伴って第２ラチェットばね３１が縮み、第２カム部材２４は回転しない状態、すなわち静止状態に保たれる。 Further, the above-described second ratchet mechanism 30 restricts the rotation direction of the second cam member 24 only to the direction indicated by the arrow 29 that is opposite to the direction indicated by the arrow 26. That is, when the operation knob 20 is rotated in the arrow 29 direction, the second cam member 24 is rotated in the arrow 29 direction via the second ratchet mechanism 30 and the second flange portion 25. However, when the operation knob 20 is rotated in the direction of the arrow 26, the second ratchet mechanism 30 slips, and the second ratchet spring 31 is contracted accordingly, and the second cam member 24 is not rotated. Stay stationary.

When the pressing protrusion 32e of the swinging portion 32b of the first swinging member 32 receives the biasing force of the first disc spring 12 of the first push switch, the engaging portion 32a of the first swinging member 32 becomes the first The cam member 22 is always kept in contact with the cam surface 22a.

同様に、第２カム部材２４と第２プッシュスイッチとの間には、図１に示すように、第２揺動部材３４を配置してある。この第２揺動部材３４は、第２カム部材２４のカム面２４ａに係合する係合部３４ａと、第２プッシュスイッチの第２皿ばね１４を押圧可能な押圧突起を有する揺動部３４ｂとを有し、一方の軸部３４ｃが図１の基台１の軸穴１０に挿入され、他方の軸部３４ｄが基台１上に固定される図示しない軸受部材の側部に形成した軸穴に挿入される。第２揺動部材３４の揺動部３４ｂの押圧突起が第２プッシュスイッチの第２皿ばね１４の付勢力を受けることにより、この第２揺動部材３４の係合部３４ａは、第２カム部材２４のカム面２４ａに常時当接した状態に保持される。 Similarly, a second swing member 34 is disposed between the second cam member 24 and the second push switch as shown in FIG. The second swinging member 34 includes an engaging portion 34a that engages with the cam surface 24a of the second cam member 24, and a swinging portion 34b that has a pressing protrusion capable of pressing the second disc spring 14 of the second push switch. A shaft formed on the side portion of a bearing member (not shown) in which one shaft portion 34c is inserted into the shaft hole 10 of the base 1 in FIG. 1 and the other shaft portion 34d is fixed on the base 1 Inserted into the hole. When the pressing protrusion of the swinging portion 34b of the second swinging member 34 receives the urging force of the second disc spring 14 of the second push switch, the engaging portion 34a of the second swinging member 34 becomes the second cam. The member 24 is always kept in contact with the cam surface 24a of the member 24.

上述した第１皿ばね１２等を含む第１プッシュスイッチは、操作つまみ２０の図１に示す矢印２６方向の回転を検出する第１回転検出部材を構成し、上述した第２皿ばね１４等を含む第２プッシュスイッチは、操作つまみ２０の図１に示す矢印２９方向の回転を検出する第２回転検出部材を構成している。 The first push switch including the first disc spring 12 and the like described above constitutes a first rotation detection member that detects the rotation of the operation knob 20 in the direction of the arrow 26 shown in FIG. The included second push switch constitutes a second rotation detection member that detects the rotation of the operation knob 20 in the direction of the arrow 29 shown in FIG.

The 1st drive member which drives the 1st push switch containing is constituted. Similarly, the second cam member 24 and the second swinging member 34 described above are the second rotation detecting member, that is, the second disc spring 14 described above, in accordance with the rotation of the operation knob 20 in the direction of the arrow 29 shown in FIG. The 2nd drive member which drives the 2nd push switch containing etc. is comprised.

なお、第１駆動部材を構成する第１カム部材２２のカム面２２ａと、第１揺動部材３２の係合部３２ａとは、取付部材１７の昇降に際して、取付部材１７の昇降ストロークに応じた距離だけわずかながら、互いに滑り合って相対移動可能となっている。すなわち、これらの第１カム部材２２のカム面２２ａと第１揺動部材３２の係合部３２ａとにより、取付部材１７の昇降の際に第１皿ばね１２等を含む第１プッシュスイッチを駆動しないように規制可能な手段が構成されている。 The cam surface 22a of the first cam member 22 constituting the first drive member and the engaging portion 32a of the first swing member 32 correspond to the lifting stroke of the mounting member 17 when the mounting member 17 moves up and down. Although they are only a short distance apart, they can slide relative to each other. That is, the first push switch including the first disc spring 12 and the like is driven by the cam surface 22a of the first cam member 22 and the engaging portion 32a of the first swing member 32 when the mounting member 17 is raised and lowered. Means that can be regulated are configured so as not to be.

同様に、第２駆動部材を構成する第２カム部材２４のカム面２４ａと、第２揺動部材３４の係合部３４ａとは、取付部材１７の昇降に際して、取付部材１７の昇降ストロークに応じた距離だけわずかながら、互いに滑り合って相対移動可能となっている。すなわち、これらの第２カム部材２４のカム面２４ａと第２揺動部材３４の係合部３４ａとにより、取付部材１７の昇降の際に第２皿ばね１４等を含む第２プッシュスイッチを駆動しないように規制可能な手段が構成されている。 Similarly, the cam surface 24a of the second cam member 24 constituting the second drive member and the engaging portion 34a of the second swing member 34 correspond to the lifting stroke of the mounting member 17 when the mounting member 17 moves up and down. It is possible to move relative to each other by sliding slightly. That is, the cam surface 24a of the second cam member 24 and the engaging portion 34a of the second swing member 34 drive the second push switch including the second disc spring 14 and the like when the mounting member 17 is raised and lowered. Means that can be regulated are configured so as not to be.

［操作つまみの所定の一方向の回転の検出］
このように構成した本実施形態において、操作つまみ２０を図１の矢印２６方向に回転させると、上述したように第１ラチェット機構２７、第１つば部２３を介して第１カム部材２２が回転する。この第１カム部材２２の回転に伴い、第１揺動部材３２の係合部３２ａが第１カム部材２２の凹凸のカム面２２ａ上を相対的に摺動する。これにより第１揺動部材３２が揺動して、その揺動部３２ｂの押圧突起３２ｅが略直線的に昇降し、第１プッシュスイッチを構成する第１皿ばね１２を間欠的に押圧する。したがって、第１皿ばね１２が間欠的に撓んで、その可動接点が中央固定接点２ａに接触する。すなわち、第１プッシュスイッチはオン、オフを繰り返し、この第１プッシュスイッチから操作つまみ２０の回転に応じたパルス信号が出力される。このパルス信号に応じて、操作つまみ２０の回転角、及び矢印２６で示す回転方向が検出される。 [Detection of rotation of control knob in one predetermined direction]
In the present embodiment configured as described above, when the operation knob 20 is rotated in the direction of the arrow 26 in FIG. 1, the first cam member 22 is rotated via the first ratchet mechanism 27 and the first collar portion 23 as described above. To do. As the first cam member 22 rotates, the engaging portion 32 a of the first swing member 32 slides relatively on the uneven cam surface 22 a of the first cam member 22. As a result, the first swinging member 32 swings, and the pressing protrusion 32e of the swinging portion 32b moves up and down substantially linearly to intermittently press the first disc spring 12 constituting the first push switch. Therefore, the 1st disc spring 12 bends intermittently and the movable contact contacts the center fixed contact 2a. That is, the first push switch is repeatedly turned on and off, and a pulse signal corresponding to the rotation of the operation knob 20 is output from the first push switch. In accordance with this pulse signal, the rotation angle of the operation knob 20 and the rotation direction indicated by the arrow 26 are detected.

なお、このような操作つまみ２０の図１に示す矢印２６方向の回転操作の間、上述したように第２ラチェット機構３０の働きにより、第２カム部材２４は回転せず、したがって第２揺動部材３４は揺動せず、第２皿ばね１４等を含む第２プッシュスイッチはオフに保たれる。また、操作つまみ２０が下方に押圧されない限りは、すなわち取付部材１７が下降しない限りは、第２分割部１９に設けた押圧突起１９ｅが第３皿ばね１６等を含む第３プッシュスイッチを駆動することがない。したがって、この第３プッシュスイッチもオフに保たれる。 During the rotation operation of the operation knob 20 in the direction of the arrow 26 shown in FIG. 1, the second cam member 24 does not rotate due to the action of the second ratchet mechanism 30 as described above, and therefore the second swinging movement. The member 34 does not swing, and the second push switch including the second disc spring 14 and the like is kept off. Further, as long as the operation knob 20 is not pressed downward, that is, unless the mounting member 17 is lowered, the pressing protrusion 19e provided on the second divided portion 19 drives the third push switch including the third disc spring 16 and the like. There is nothing. Therefore, this third push switch is also kept off.

［操作つまみの逆方向の回転の検出］
また、操作つまみ２０を図１の矢印２９方向に回転させると、上述したように第２ラチェット機構３０、第２つば部２５を介して第２カム部材２４が回転する。この第２カム部材２４の回転に伴い、第２揺動部材３４の係合部３４ａが第２カム部材２４の凹凸のカム面２４ａ上を相対的に摺動する。これにより第２揺動部材３４が揺動して、その揺動部３４ｂの押圧突起が略直線的に昇降し、第２プッシュスイッチを構成する第２皿ばね１４を間欠的に押圧する。したがって、第２皿ばね１４が間欠的に撓んで、その可動接点が中央固定接点３ａに接触する。すなわち、第２プッシュスイッチはオン、オフを繰り返し、この第２プッシュスイッチから操作つまみ２０の回転に応じたパルス信号が出力される。このパルス信号に応じて、操作つまみ２０の回転角、及び矢印２９で示す回転方向が検出される。 [Detection of reverse rotation of control knob]
Further, when the operation knob 20 is rotated in the direction of the arrow 29 in FIG. 1, the second cam member 24 is rotated via the second ratchet mechanism 30 and the second collar portion 25 as described above. As the second cam member 24 rotates, the engaging portion 34 a of the second swing member 34 slides relatively on the uneven cam surface 24 a of the second cam member 24. As a result, the second swinging member 34 swings, and the pressing protrusion of the swinging portion 34b moves up and down substantially linearly, and intermittently presses the second disc spring 14 constituting the second push switch. Therefore, the 2nd disc spring 14 bends intermittently and the movable contact contacts the center fixed contact 3a. That is, the second push switch is repeatedly turned on and off, and a pulse signal corresponding to the rotation of the operation knob 20 is output from the second push switch. In accordance with this pulse signal, the rotation angle of the operation knob 20 and the rotation direction indicated by the arrow 29 are detected.

なお、このような操作つまみ２０の図１に示す矢印２９方向の回転操作の間、上述したように第１ラチェット機構２７の働きにより、第１カム部材２２は回転せず、したがって第１揺動部材３２は揺動せず、第１皿ばね１２等を含む第１プッシュスイッチはオフに保たれる。また、操作つまみ２０が下方に押圧されない限りは、すなわち取付部材１７が下降しない限りは、第２分割部１９に設けた押圧突起１９ｅが第３皿ばね１６等を含む第３プッシュスイッチを駆動することがない。したがって、この第３プッシュスイッチもオフに保たれる。 Note that during the rotation operation of the operation knob 20 in the direction of the arrow 29 shown in FIG. 1, the first cam member 22 does not rotate by the action of the first ratchet mechanism 27 as described above, and therefore the first swinging movement. The member 32 does not swing, and the first push switch including the first disc spring 12 and the like is kept off. In addition, as long as the operation knob 20 is not pressed downward, that is, unless the mounting member 17 is lowered, the pressing protrusion 19e provided on the second divided portion 19 drives the third push switch including the third disc spring 16 and the like. There is nothing. Therefore, this third push switch is also kept off.

［操作つまみの押圧（昇降）操作の検出］
操作つまみ２０が下方に押圧されると、取り付け部材１７の軸部１８ｆ，１９ｄのそれぞれが、基台１の第１長穴５、第２長穴６内を移動して下降し、その第２分割部１９の押圧突起１９ｅが、第３プッシュスイッチの第３皿ばね１６を押圧する。これにより第３皿ばね１６が撓み、その可動接点が中央固定接点４ａに接触し、第３プッシュスイッチからオン信号が出力される。したがって例えば、操作つまみ２０を図１に示す矢印２６方向に回転させた後に、この操作つまみ２０を押圧して第３プッシュスイッチをオンにすれば、操作つまみ２０の所定の一方向の回転を確定させる処理を行なうことができる。同様に、操作つまみ２０を図１に示す矢印２９方向に回転させた後に、この操作つまみ２０を押圧して第３プッシュスイッチをオンにすれば、操作つまみ２０の所定の一方向とは逆方向の回転を確定させる処理を行なうことができる。 [Detection of pressing (lifting) operation knob]
When the operation knob 20 is pressed downward, each of the shaft portions 18f and 19d of the mounting member 17 moves and descends in the first long hole 5 and the second long hole 6 of the base 1, and the second The pressing protrusion 19e of the dividing portion 19 presses the third disc spring 16 of the third push switch. As a result, the third disc spring 16 bends, its movable contact contacts the center fixed contact 4a, and an ON signal is output from the third push switch. Therefore, for example, if the operation knob 20 is rotated in the direction of the arrow 26 shown in FIG. 1 and then the operation knob 20 is pressed to turn on the third push switch, the rotation of the operation knob 20 in one predetermined direction is confirmed. Can be processed. Similarly, if the operation knob 20 is rotated in the direction of the arrow 29 shown in FIG. 1 and then the operation knob 20 is pressed to turn on the third push switch, the operation knob 20 is in a direction opposite to a predetermined direction. It is possible to perform processing for determining the rotation of the.

［本実施形態の作用効果］
以上のように構成した本実施形態によれば、操作体である操作つまみ２０と、第１回転検出部材である第１プッシュスイッチ、第２回転検出部材である第２プッシュスイッチとの間に、操作つまみ２０の回転を第１プッシュスイッチ、第２プッシュスイッチの駆動として伝える第１カム部材２２と第１揺動部材３２とから成る第１駆動部材、及び第２カム部材２４と第２揺動部材３４とから成る第２駆動部材を設けたことから、第１プッシュスイッチ、第２プッシュスイッチを操作つまみ２０とは異なる位置に配置することができる。すなわち、第１皿ばね１２等を含む第１プッシュスイッチ、第２皿ばね１４等を含む第２プッシュスイッチを操作つまみ２０から離隔させて基台１の位置に設けることができる。したがって、操作つまみ２０の外径寸法が第１プッシュスイッチ、第２プッシュスイッチ、すなわち第１回転検出部材、第２回転検出部材の形状寸法によって制約を受けることがなく、この操作つまみ２０の外径寸法を、操作が可能な限りの小寸法に設定できる。これにより、装置の薄型化を実現できる。 [Operational effects of this embodiment]

Since the second drive member composed of the member 34 is provided, the first push switch and the second push switch can be arranged at positions different from the operation knob 20. That is, the first push switch including the first disc spring 12 and the like, and the second push switch including the second disc spring 14 and the like can be provided at the position of the base 1 separately from the operation knob 20. Therefore, the outer diameter of the operation knob 20 is not restricted by the first push switch and the second push switch, that is, the shape and dimensions of the first rotation detection member and the second rotation detection member. The dimensions can be set as small as possible. Thereby, it is possible to reduce the thickness of the apparatus.

また、第１プッシュスイッチ、第２プッシュスイッチに接続される配線を基台１に例えばインサート成形することができ、簡単で安定した配線接続構造を実現でき、信号出力系統に対する高い信頼性を確保することができる。 In addition, the wiring connected to the first push switch and the second push switch can be insert-molded in the base 1, for example, so that a simple and stable wiring connection structure can be realized, and high reliability for the signal output system is ensured. be able to.

また、第１回転検出部材、第２回転検出部材が第１皿ばね１２等を含む第１プッシュスイッチ、第２皿ばね１４等を含む第２プッシュスイッチから成るので、簡単な構成であり、製作が容易である。 Further, the first rotation detection member, the second rotation detection member are composed of a first push switch including the first disc spring 12 and the like, and a second push switch including the second disc spring 14 and the like. Is easy.

同様に、昇降検出部材が第３皿ばね１６等を含む第３プッシュスイッチから成るので、簡単な構成であり、製作が容易である。 Similarly, since the raising / lowering detection member is composed of the third push switch including the third disc spring 16 and the like, it has a simple configuration and is easy to manufacture.

また、ラチェット機構、カム部材、揺動部材、及びプッシュスイッチの組み合わせを２組設け、第１ラチェット機構２７、第１カム部材２２、第１揺動部材３２、及び第１プッシュスイッチを介して操作つまみ２０の所定の一方向の回転を検出させ、第２ラチェット機構３０、第２カム部材２４、第２揺動部材３４、及び第２プッシュスイッチを介して操作つまみ２０の逆方向の回転を検出させるようにしたことから、第１プッシュスイッチ、第２プッシュスイッチのそれぞれによって、操作つまみ２０の異なる回転方向も簡単に検出することができる。 In addition, two combinations of ratchet mechanism, cam member, swing member, and push switch are provided and operated via the first ratchet mechanism 27, first cam member 22, first swing member 32, and first push switch. The rotation of the knob 20 is detected in one predetermined direction, and the reverse rotation of the operation knob 20 is detected via the second ratchet mechanism 30, the second cam member 24, the second swing member 34, and the second push switch. Therefore, the different rotation directions of the operation knob 20 can be easily detected by the first push switch and the second push switch, respectively.

また、取付部材１７を昇降可能に基台１に保持させ、取付部材１７を構成する第２分割部１９の押圧突起１９ｅによって第３プッシュスイツチを押圧可能にしたことから、操作つまみ２０の回転と昇降の双方を検出可能な複合操作型電気部品として活用できる。これにより優れた検出機能を確保できると共に、上述したように複合操作型電気部品における薄型化を実現できる。また取付部材１７の昇降の際に、第１プッシュスイッチ、第２プッシュスイッチから信号を出力させないようにすることができ、安定した信号出力性能を確保できる。 Further, since the mounting member 17 is held on the base 1 so as to be movable up and down, and the third push switch can be pressed by the pressing protrusion 19e of the second divided portion 19 constituting the mounting member 17, the rotation of the operation knob 20 can be performed. It can be used as a composite operation type electrical component that can detect both up and down. As a result, an excellent detection function can be ensured, and the composite operation type electrical component can be thinned as described above. Further, when the mounting member 17 is moved up and down, signals can be prevented from being output from the first push switch and the second push switch, and stable signal output performance can be ensured.

また、第１プッシュスイッチ、第２プッシュスイッチ、第３プッシュスイッチのそれぞれを覆う第１接着シート１１、第２接着シート１３、第３接着シート１５を備えていることから、これらの第１〜第３プッシュスイッチに対する優れた耐塵埃性を確保でき、この点でも信頼性の高い装置とすることができる。 In addition, since the first adhesive sheet 11, the second adhesive sheet 13, and the third adhesive sheet 15 that cover each of the first push switch, the second push switch, and the third push switch are provided, these first to first switches Excellent dust resistance for the 3-push switch can be ensured, and in this respect also, a highly reliable device can be obtained.

なお、上記実施形態では、図１の矢印２６で示す所定の一方向と、同図１の矢印２９で示す逆方向との２方向の操作つまみ２０の回転の検出を実現させているが、いずれか一方向のみの検出で済む場合には、カム部材、揺動部材を含む駆動部材と、プッシュスイッチ等の回転検出部材との組み合わせを単に１組だけ設ける構成とすればよい。 In the above embodiment, the detection of the rotation of the operation knob 20 in two directions, that is, the predetermined direction indicated by the arrow 26 in FIG. 1 and the reverse direction indicated by the arrow 29 in FIG. If detection in only one direction is sufficient, a combination of a drive member including a cam member and a swinging member and a rotation detection member such as a push switch may be provided.

また、操作つまみ２０の昇降操作を検出する必要がない場合には、取付部材１７の第２分割部１９に設けられる押圧突起１９ｅ、及び昇降検出部材である第３プッシュスイッチを除いた構成にすればよい。この場合、基台１に形成される第１長穴５、第２長穴６は、取付部材１７の軸部１８ｆ，１９ｄが挿入可能な円形の穴に設定すればよい。 Further, when it is not necessary to detect the raising / lowering operation of the operation knob 20, the configuration is such that the pressing protrusion 19 e provided on the second divided portion 19 of the mounting member 17 and the third push switch as the raising / lowering detection member are excluded. That's fine. In this case, the first long hole 5 and the second long hole 6 formed in the base 1 may be set as circular holes into which the shaft portions 18f and 19d of the mounting member 17 can be inserted.
