【考案の詳細な説明】
本考案は、電子時計に用いられるモータのロータ規正機
構に関するものである。[Detailed Description of the Invention] The present invention relates to a rotor regulating mechanism for a motor used in an electronic timepiece.
従来、電子時計に用いられているモータには、時計の時
刻修正時のリューズ操作によるロータぐるぐる回わり防
止の為にロータ規正機構が設けられている。Conventionally, motors used in electronic watches are provided with a rotor regulating mechanism to prevent the rotor from spinning around when the crown is operated when adjusting the time of the watch.
このロータ規正機構は、時計の時刻修正後にモータのロ
ータ磁極静止位置とモータ駆動パルスの極性を対応させ
、時刻修正後のモータ蛇動の零秒発進を行い、時刻修正
を正確にする為のものである。This rotor regulation mechanism is used to make the time correction accurate by matching the static position of the motor's rotor magnetic pole and the polarity of the motor drive pulse after the time is corrected, and by starting the motor's serpentine motion at zero seconds after the time is corrected. It is.
次に、従来より考案されているロータ規正機構を第１図
に示す一例によって説明する。Next, a conventionally devised rotor regulating mechanism will be explained using an example shown in FIG.

構造である。The rotor is composed of a rotor magnet 1, a rotor pinion 2, and rotor magnet frames 3 and 4. Although not shown in the drawing, a rotor regulating lever 5 is operated by operating a crown, and the rotor is rotated at right angles to the direction of the rotation axis of the rotor pinion 2. The structure is such that a mechanical regulating force is applied to the rotor magnet frame 3 to regulate the rotor.
この時、ロータ磁石を直接規正しないのは、ロータ磁石
が一般的に割れやすい材質である為である。The reason why the rotor magnet is not directly adjusted at this time is because the rotor magnet is generally made of a material that is easily broken.
しかし、この様な構造では、ロータ磁石枠３が円柱の形
となる為に、小型化を要求される電子腕時計には不適当
であり、又、モータの性能面でも不要な付加重量が多過
ぎ、外部直流磁界の加わる環境下に置かれると、ロータ
の駆動パルス１個分で通常１ステップ動作するロータが
、２ステップ動作する現象が実際のテストにより観測さ
れている。However, in this structure, the rotor magnet frame 3 has a cylindrical shape, which is not suitable for electronic wristwatches that require miniaturization, and also adds too much unnecessary weight in terms of motor performance. It has been observed in actual tests that when placed in an environment where an external DC magnetic field is applied, the rotor, which normally moves one step per rotor drive pulse, moves two steps.
（慣性質量が大きくなる為。(This is because the inertial mass increases.
）この様に、従来より考案されているロータ規正機構で
は、ロータ磁石枠の形状と重量に欠点があった。) As described above, the conventionally devised rotor regulating mechanisms have drawbacks in the shape and weight of the rotor magnet frame.
本考案は、上記の欠点を除去するもので、モータの小型
化と、外部直流磁界の加わる環境下に於けるモータの正
常動作能力を強化する事を目的とする。The present invention aims to eliminate the above-mentioned drawbacks, and aims to reduce the size of the motor and strengthen the normal operating ability of the motor in an environment where an external DC magnetic field is applied.
次に、本考案を第２図に示す一実施例によって説明する
。Next, the present invention will be explained with reference to an embodiment shown in FIG.
ロータは、ロータ磁石６とロータカナ７及び、円錐状の

枠８に加えられロータが、規正される構造である。The rotor is composed of a rotor magnet 6, a rotor pinion 7, a conical rotor magnet frame 8, and a planar rotor magnet frame 9. Although not shown in the drawing, a rotor regulating lever 10 is operated by operating the crown, and the rotor pinion The structure is such that a mechanical regulating force is applied to the rotor magnet frame 8 obliquely to the rotational axis direction of the rotor, thereby regulating the rotor.
以上の様に、本考案によれば、ロータ規正用のロータ磁
石枠形状を円錐にする事により、ロータ規正レバーとの
接触性能を損わず、小型、軽量のロー夕が可能であり、
しかも、外部直流磁界に対しても強い構造のロータ規正
機構が実現でき、その効果は絶大である。As described above, according to the present invention, by making the rotor magnet frame shape conical for rotor regulation, a small and lightweight rotor is possible without impairing the contact performance with the rotor regulation lever.
Moreover, it is possible to realize a rotor regulating mechanism that is resistant to external DC magnetic fields, and its effects are tremendous.
