The cam crest 24b can repeatedly engage and disengage with the ball 31 urged downward as the cam crest member 24 rotates in the rotation input device, and can give a click feeling to the rotation operation.

図６には回転入力装置の断面図を、図７にはボール３１がカム山２４ｂの頂部にある場合におけるボール３１付近の拡大断面図を、それぞれ示している。回転体２は中央操作部２０が周辺操作部２１の腕部によって昇降自在に保持されて一体化しており、駆動体２２は中央操作部２０の下面に配置され、その押し込み操作時に一体的に昇降可能としている。   FIG. 6 shows a sectional view of the rotary input device, and FIG. 7 shows an enlarged sectional view of the vicinity of the ball 31 when the ball 31 is at the top of the cam crest 24b. The rotating body 2 is integrated with the central operation unit 20 being held up and down by the arms of the peripheral operation unit 21, and the driving body 22 is disposed on the lower surface of the central operation unit 20, and is lifted and lowered integrally during the pushing operation. It is possible.

カム山部材２４は、上述のように係合部２４ｃと連係板２３の被係合部２３ａが係合すると共に、図７に示すように周辺操作部２１の下面に形成された係止片２１ａが連係板２３の貫通孔２３ｃを介して係止されて板厚方向へ抜け止め、カム山部材２４の逃げ穴２４ｄ内に収容される。さらに、カム山部材２４はベアリング３４の外周面に固定されており、回転体２全体は基台１に対して回転自在とされると共に、カム山部材２４の外周面と基台１の中間壁１４の内周面との間には間隙部１６が形成されている。   As described above, the cam crest member 24 is engaged with the engaged portion 24c and the engaged portion 23a of the linkage plate 23, and the locking piece 21a formed on the lower surface of the peripheral operation portion 21 as shown in FIG. Is locked through the through hole 23 c of the linkage plate 23 to prevent it from coming off in the thickness direction, and is accommodated in the relief hole 24 d of the cam crest member 24. Further, the cam crest member 24 is fixed to the outer peripheral surface of the bearing 34, and the entire rotating body 2 is rotatable with respect to the base 1, and the outer peripheral surface of the cam crest member 24 and the intermediate wall between the base 1. A gap portion 16 is formed between the inner peripheral surface of 14.

カム山部材２４の段部２４ａには、上述のようにボール３１が載置されており、回転体２の回転に伴ってカム山２４ｂの凹凸に対して係脱を繰り返す。ボール３１の上方には弾性部材３０が配置される。弾性部材３０は、図２に示すように３個所に脚部３０ａが形成されており、図６に示すように脚部３０ａを略Ｌ字状に折り曲げて基台１に対して固定される。   As described above, the ball 31 is placed on the step portion 24 a of the cam crest member 24, and is repeatedly engaged and disengaged with respect to the irregularities of the cam crest 24 b as the rotating body 2 rotates. An elastic member 30 is disposed above the ball 31. As shown in FIG. 2, the elastic member 30 has leg portions 30 a formed at three locations. As shown in FIG. 6, the leg portions 30 a are bent into a substantially L shape and fixed to the base 1.

上述のように構成された本実施形態における回転入力装置は、使用者が周辺操作部２１を回転操作することによって回転体２が回転し、そのカム山部材２４の回転を検出部３で検出して、検出した電気信号を上位装置へ送出することにより、電子機器への回転入力が行われる。また、使用者が中央操作部２０を可動接点２２ａのバネ力に抗して押し込み操作することによって、駆動体２２が可動接点２２ａを反転させて固定接点２２ｂと導通させ、検出した電気信号を上位装置へ送出することにより、電子機器への押圧操作入力が行われる。 このような回転入力装置によれば、例えば電子機器のメニュー画面に表示された表示内容の選択を周辺操作部２１の回転操作により行い、中央操作部２０の押圧操作によって確定入力することができ、スムーズな入力操作を行うことができる。   In the rotation input device according to the present embodiment configured as described above, the rotating body 2 rotates when the user rotates the peripheral operation unit 21, and the rotation of the cam crest member 24 is detected by the detection unit 3. Then, the detected electrical signal is sent to the host device, whereby rotation input to the electronic device is performed. In addition, when the user pushes the central operation unit 20 against the spring force of the movable contact 22a, the driving body 22 inverts the movable contact 22a and conducts it with the fixed contact 22b. By sending it to the apparatus, a pressing operation input to the electronic device is performed. According to such a rotation input device, for example, selection of display contents displayed on the menu screen of the electronic device can be performed by rotating operation of the peripheral operation unit 21, and fixed input can be performed by pressing operation of the central operation unit 20. Smooth input operation can be performed.

そして、本実施形態における回転入力装置は回転操作時に図７に示すように、カム山２４ｂにボール３１が乗り上げると、ボール３１は上方に移動するが、ボール３１は弾性部材３０により下方に付勢されているので、抵抗力が働く。このようにボール３１がカム山２４ｂに乗り上げることで抵抗力に伴うクリック感触が付与される。カム山２４ｂはカム山部材２４の外周面において同じピッチで全周に渡って形成されているので、回転体２がカム山２４ｂのピッチ分回転する度にボール３１に対して抵抗力が働き、クリック感触を付与することができる。   As shown in FIG. 7, the rotation input device according to the present embodiment moves upward when the ball 31 rides on the cam crest 24 b, but the ball 31 is biased downward by the elastic member 30. Because it is, resistance works. Thus, when the ball 31 rides on the cam mountain 24b, a click feeling associated with the resistance force is given. Since the cam crest 24b is formed over the entire circumference at the same pitch on the outer peripheral surface of the cam crest member 24, a resistance force acts on the ball 31 each time the rotating body 2 rotates by the pitch of the cam crest 24b, A click feeling can be imparted.

ここで、段部２４ａはカム山部材２４の外周面において外側に向かう下り傾斜状に形成されているので、カム山２４ｂに係脱するボール３１は常に外側に押し出される方向の力を受けている。したがって、ボール３１はカム山部材２４の外周面のうち垂直面に対してはほとんど接触せず、カム山２４ｂ及び基台１側の収納部１７に接触した状態で係脱を繰り返す。このため、ボール３１を安定して回転させることができる。   Here, since the step portion 24a is formed in a downwardly inclined shape toward the outer side on the outer peripheral surface of the cam crest member 24, the ball 31 engaged with and disengaged from the cam crest 24b always receives a force in a direction to be pushed outward. . Therefore, the ball 31 hardly contacts the vertical surface of the outer peripheral surface of the cam crest member 24 and repeats engagement and disengagement in a state where the ball 31 is in contact with the cam crest 24 b and the storage portion 17 on the base 1 side. For this reason, the ball 31 can be rotated stably.

このように、クリック機構４を構成する弾性部材３０及びボール３１を回転体２の回転軸方向から取付けられるような構造としたことにより、回転入力装置の組立てが容易であり、また弾性部材３０を板バネにより構成したことで、回転入力装置の小型化及び薄型化をも図ることができる。   As described above, the structure in which the elastic member 30 and the ball 31 constituting the click mechanism 4 can be attached from the direction of the rotation axis of the rotating body 2 makes it easy to assemble the rotary input device. By comprising the leaf spring, it is possible to reduce the size and thickness of the rotary input device.

これまで本発明の実施形態について説明したが、本発明の適用はこれら実施形態に限られるものではなく、その技術的思想の範囲内において様々に適用されうるものである。   Although the embodiments of the present invention have been described so far, the application of the present invention is not limited to these embodiments and can be variously applied within the scope of the technical idea.
