Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotary switch for allowing the rotating condition of an operation member to be sensed during rotating the operation member, resulting in the improved operability of the operation member. <P>SOLUTION: On a winding core 12 as the operation member operable in the rotating direction, a magnet member 14 is mounted to be rotated integrally therewith. The rotary field of the magnet member 14 is detected by a magnetic sensor 15. The magnet member 14 has a non-circular portion 26 formed non-circular in cross section. A leaf spring 28 is brought into elastic contact with the non-circular portion 26 being rotated together with the winding core 12. Thus, when the winding core 12 is rotated to rotate the magnet member 14, the rotary field of the magnet member 14 can be detected by the magnetic sensor 15 and the non-circular portion 26 is rotated with the rotation of the winding core 12 to ride over the elastically deformed leaf spring 28. As a result, a clicking feel can be imparted to the winding core 12. <P>COPYRIGHT: (C)2011,JPO&INPIT

この発明は、電子腕時計などの電子機器に用いられる回転スイッチに関する。   The present invention relates to a rotary switch used in an electronic device such as an electronic wristwatch.

例えば、電子腕時計においては、特許文献１に記載されているように、時刻を修正する際に、巻真を所定位置に引き出して回転させることにより、巻真の回転に応じて指針を運針させる時刻を修正する回転スイッチを備えた構成のもが知られている。   For example, in an electronic wristwatch, as described in Patent Document 1, when the time is corrected, the time when the pointer is moved according to the rotation of the winding stem by pulling the winding stem to a predetermined position and rotating it. A configuration having a rotary switch for correcting the above is also known.

特開２００８−１２２３７７号公報JP 2008-122377 A

このような電子腕時計は、腕時計ケースに巻真を、その軸方向における第１の位置と第２の位置とに移動可能に設けると共に、巻真の軸を中心とする回転方向にも回転可能に設け、この巻真に磁石を設け、この磁石の円周方向に位置する腕時計ケース内に磁気センサを設けた構成になっている。   In such an electronic wristwatch, the winding stem is provided on the wristwatch case so as to be movable between the first position and the second position in the axial direction, and is also rotatable in the rotation direction around the winding stem axis. And a magnet is provided in the winding stem, and a magnetic sensor is provided in a wristwatch case positioned in the circumferential direction of the magnet.

この種の電子腕時計では、巻真を押し込んだ第１の位置状態のときに、巻真に設けられた磁石が磁気センサから離れ、また巻真を引き出した第２の位置状態のときに、巻真と共に磁石が移動して磁気センサに対応し、この状態で巻真を回転させると、磁石が巻真と共に回転し、この回転する磁石の磁界を磁気センサが検出し、この磁気センサで検出された検出データに基づいて指針を運針させることにより、時刻を修正している。   In this type of electronic wristwatch, when the winding stem is pushed into the first position state, the magnet provided on the winding stem is separated from the magnetic sensor, and when the winding stem is pulled out, the winding stem is pulled out. If the magnet moves with true and corresponds to the magnetic sensor, and the winding stem is rotated in this state, the magnet rotates with the winding stem, and the magnetic sensor detects the magnetic field of the rotating magnet and is detected by this magnetic sensor. The time is corrected by moving the hands based on the detected data.

しかしながら、このような従来の電子腕時計においては、巻真を引き出した第２の位置状態のときに、巻真を回転させて磁石を巻真と共に回転させ、この磁石による回転磁界を磁気センサが非接触状態で検出する構成であるから、巻真を回転させても、巻真にクリック感がないため、巻真の回転状態を感覚的に知ることができないという問題がある。   However, in such a conventional electronic wristwatch, when the winding stem is in the second position state, the winding stem is rotated to rotate the magnet together with the winding stem, and the magnetic sensor detects the rotating magnetic field generated by the magnet. Since the detection is performed in the contact state, there is a problem that even if the winding stem is rotated, there is no click feeling in the winding stem, so that the rotation state of the winding stem cannot be sensed.

この発明が解決しようとする課題は、巻真などの操作部材を回転させた際に、その操作部材の回転状態を感覚的に知ることができ、これにより操作部材の操作性を向上させることができる回転スイッチを提供することである。   The problem to be solved by the present invention is that when an operation member such as a winding stem is rotated, the rotation state of the operation member can be sensuously known, thereby improving the operability of the operation member. It is to provide a rotary switch that can.

この発明は、上記課題を解決するために、次のような構成要素を備えている。
請求項１に記載の発明は、回転方向に操作可能な操作部材と、この操作部材に取り付けられて前記操作部材と一体的に回転する磁石部材と、この磁石部材の回転を検出する磁気センサと、前記操作部材もしくは前記磁石部材に設けられて断面形状が非円形状に形成された非円形部と、この非円形部に弾接し、前記操作部材を回転させた際に前記非円形部によって弾性変形して前記非円形部が乗り越えるばね部材とを備えていることを特徴とする回転スイッチである。 In order to solve the above problems, the present invention includes the following components.
The invention according to claim 1 is an operation member operable in a rotation direction, a magnet member attached to the operation member and rotating integrally with the operation member, and a magnetic sensor detecting rotation of the magnet member. A non-circular portion having a non-circular cross-sectional shape provided on the operation member or the magnet member, and elastically by the non-circular portion when the non-circular portion is elastically contacted and rotated. The rotary switch is provided with a spring member that is deformed to overcome the non-circular portion.

請求項２に記載の発明は、前記ばね部材が、前記非円形部を弾力的に挟み付ける一対の弾接片を備えていることを特徴とする請求項１に記載の回転スイッチである。   A second aspect of the present invention is the rotary switch according to the first aspect, wherein the spring member includes a pair of elastic contact pieces that elastically sandwich the non-circular portion.

請求項３に記載の発明は、前記磁石部材が、磁界を発生する磁石と、この磁石を包み込む樹脂部とを備え、この樹脂部に前記非円形部が設けられていることを特徴とする請求項１または請求項２に記載の回転スイッチである。   According to a third aspect of the present invention, the magnet member includes a magnet that generates a magnetic field and a resin portion that wraps the magnet, and the non-circular portion is provided in the resin portion. The rotary switch according to claim 1 or claim 2.

この発明によれば、操作部材を回転させて磁石部材を操作部材と共に一体的に回転させると、この磁石部材の回転を磁気センサで検出することができると共に、操作部材が回転すると、非円形部も回転し、この非円形部の回転に伴って非円形部がばね部材を弾性変形させて乗り越えることにより、操作部材にクリック感を付与することができる。このため、操作部材を回転させた際に、その操作部材の回転状態を感覚的に知ることができ、これにより操作部材の操作性を向上させることができる。   According to this invention, when the operating member is rotated and the magnet member is rotated together with the operating member, the rotation of the magnet member can be detected by the magnetic sensor, and when the operating member rotates, the non-circular portion When the non-circular part rotates, the non-circular part elastically deforms the spring member and gets over, so that a click feeling can be given to the operation member. For this reason, when the operating member is rotated, the rotational state of the operating member can be known sensuously, thereby improving the operability of the operating member.

以下、図１〜図１０参照して、この発明を指針式の電子腕時計に適用した一実施形態について説明する。
この電子腕時計は、図１に示すように、腕時計ケース１を備えている。この腕時計ケース１の上部開口部には、時計ガラス２がパッキン２ａを介して取り付けられており、この腕時計ケース１の下部には、裏蓋３が防水リング３ａを介して取り付けられている。 An embodiment in which the present invention is applied to a pointer-type electronic wristwatch will be described below with reference to FIGS.
As shown in FIG. 1, the electronic wristwatch includes a wristwatch case 1. A watch glass 2 is attached to the upper opening of the watch case 1 via a packing 2a, and a back cover 3 is attached to the lower portion of the watch case 1 via a waterproof ring 3a.

また、この腕時計ケース１の内部には、図１に示すように、時計モジュール４が中枠５によって設けられている。この時計モジュール４は、指針を運針する時計ムーブメント（図示せず）と、時刻を修正するための時刻修正装置６とを備えている。この場合、時計モジュール４の上面には、文字板７が設けられており、この文字板７の上面には、リング状の見切部材８が設けられている。   In addition, as shown in FIG. 1, a watch module 4 is provided in the wristwatch case 1 by an inner frame 5. The timepiece module 4 includes a timepiece movement (not shown) for moving the hands, and a time adjustment device 6 for correcting the time. In this case, a dial plate 7 is provided on the upper surface of the timepiece module 4, and a ring-shaped parting member 8 is provided on the upper surface of the dial plate 7.

時刻修正装置６は、図１に示すように、腕時計ケース１の側壁部に回転可能に挿入されて外部に突出する竜頭１０と、この竜頭１０に取り付けられて時計モジュール４内の地板１１に軸方向に移動操作可能で且つその軸を中心とする回転方向にも回転操作可能に設けられた操作部材である巻真１２と、この巻真１２の軸方向における移動位置を規制する位置規制部材１３（図３参照）と、巻真１２にスライド可能に設けられて巻真１２と共に回転する磁石部材１４と、この磁石部材１４の円周方向に位置して磁石部材１４の回転を検出する磁気センサ１５とを備えている。   As shown in FIG. 1, the time adjustment device 6 includes a crown 10 that is rotatably inserted into the side wall portion of the watch case 1 and protrudes to the outside, and a shaft 11 attached to the crown 10 and attached to the main plate 11 in the timepiece module 4. A winding stem 12 that is an operating member that can be moved in the direction of rotation and that can also be rotated in the rotation direction around the axis, and a position regulating member 13 that regulates the movement position of the winding stem 12 in the axial direction. (See FIG. 3), a magnet member 14 that is slidably provided on the winding stem 12 and rotates together with the winding stem 12, and a magnetic sensor that is positioned in the circumferential direction of the magnet member 14 and detects the rotation of the magnet member 14 15.

この場合、巻真１２は、図１に示すように、ほぼ丸棒状に形成され、その一端部（図１では右端部）に竜頭１０が取り付けられている。この竜頭１０は、腕時計ケース１の側壁部に設けられた貫通孔１ａに外側から挿入されている。また、この巻真１２は、図１に示すように、その他端部（図１では左端部）が地板１１に軸方向に移動操作可能で、且つその軸を中心とする回転方向にも回転操作可能に取り付けられている。これにより、巻真１２は、腕時計ケース１の外部に位置する竜頭１０を引き出し方向に操作すると、これに伴って軸方向に移動し、また竜頭１０を回転方向に操作すると、軸回りに回転するように構成されている。   In this case, the winding stem 12 is formed in a substantially round bar shape as shown in FIG. 1, and the crown 10 is attached to one end portion (right end portion in FIG. 1). The crown 10 is inserted from the outside into a through hole 1 a provided in the side wall portion of the watch case 1. Further, as shown in FIG. 1, the winding stem 12 can be operated to move the other end portion (the left end portion in FIG. 1) in the axial direction with respect to the base plate 11 and can also be rotated in the rotation direction around the axis. It is attached as possible. Thus, the winding stem 12 moves in the axial direction when the crown 10 located outside the watch case 1 is operated in the pulling direction, and rotates around the axis when the crown 10 is operated in the rotating direction. It is configured as follows.

また、この巻真１２は、図１、図３および図４に示すように、そのほぼ中間部に小径の段差凹部１２ａが環状に設けられている。この段差凹部１２ａにおける時計モジュール１の内部側に位置する先端側（図４では左端側）には、図１および図４に示すように、後述する磁石部材１４をスライド可能に取り付けるための、断面形状が四角形状の角棒状に形成された係合軸部１６が設けられている。   Further, as shown in FIGS. 1, 3 and 4, the winding stem 12 is provided with a small-diameter stepped recess 12a in an annular shape at an almost middle portion thereof. As shown in FIGS. 1 and 4, a cross section for slidably attaching a magnet member 14 to be described later to the front end side (the left end side in FIG. 4) located on the inner side of the timepiece module 1 in the stepped recess 12 a. An engagement shaft portion 16 having a quadrangular rectangular bar shape is provided.

さらに、この巻真１２の内部側に位置する係合軸部１６の先端部(図４では左端部)には、図１および図４に示すように、小径の軸部１２ｂが設けられている。この軸部１２ｂは、丸棒状に形成され、地板１１に設けられたガイド穴１１ａ内に軸方向に移動可能で且つその軸を中心に回転可能な状態で挿入されている。これにより、巻真１２は、図３および図４に示すように、軸方向（矢印Ｘ方向）に押し込まれた第１の位置と、図１０に示すように、軸方向（矢印Ｙ方向）に引き出された第２の位置とに移動するように構成されている。   Furthermore, as shown in FIGS. 1 and 4, a small-diameter shaft portion 12 b is provided at the distal end portion (left end portion in FIG. 4) of the engagement shaft portion 16 located on the inner side of the winding stem 12. . The shaft portion 12b is formed in a round bar shape, and is inserted into a guide hole 11a provided in the base plate 11 so as to be movable in the axial direction and rotatable about the shaft. Thereby, as shown in FIGS. 3 and 4, the winding stem 12 is pushed in the axial direction (arrow X direction) and in the axial direction (arrow Y direction) as shown in FIG. It is comprised so that it may move to the 2nd position pulled out.

位置規制部材１３は、図３および図１０に示すように、オシドリ２０、オシドリばね２１、スイッチ板２２、および押え板２３を備えている。オシドリ２０は、図３および図１０に示すように、平板状に形成され、地板１１に設けられた支持軸１７に回転可能に取り付けられ、巻真１２の軸方向への移動に応じて支持軸１７を中心に回転するように構成されている。   As shown in FIGS. 3 and 10, the position restricting member 13 includes a mandarin duck 20, a duck spring 21, a switch plate 22, and a presser plate 23. As shown in FIGS. 3 and 10, the mandarin duck 20 is formed in a flat plate shape, is rotatably attached to a support shaft 17 provided on the base plate 11, and is supported by the axial movement of the winding stem 12. 17 is configured to rotate around 17.

すなわち、オシドリ２０には、図３および図１０に示すように、巻真１２の段差凹部１２ａ内に配置される連動アーム部２０ａと、オシドリばね２１によって弾力的に位置規制される連動ピン２０ｂと、スイッチ板２２をオシドリ２０と共に回転させる連結ピン２０ｃとが設けられている。これにより、オシドリ２０は、図３および図１０に示すように、巻真１２が軸方向に移動すると、巻真１２の段差凹部１２ａの移動に伴って連動アーム部２０ａが揺動することにより、支持軸１７を中心に回転するように構成されている。   That is, as shown in FIG. 3 and FIG. 10, the shorebird 20 includes an interlocking arm portion 20 a disposed in the stepped recess 12 a of the winding stem 12, and an interlocking pin 20 b that is elastically regulated by the shoreline spring 21. A connection pin 20c for rotating the switch plate 22 together with the shoreline 20 is provided. 3 and 10, when the winding stem 12 moves in the axial direction, the interlocking arm portion 20a swings with the movement of the stepped recess 12a of the winding stem 12. It is configured to rotate about the support shaft 17.

オシドリばね２１は、図３および図１０に示すように、板ばねであり、オシドリ２０の近傍に位置する箇所の地板１１に固定され、オシドリ２０の連動ピン２０ｂを弾力的に保持して位置規制することにより、オシドリ２０の回転位置を規制して巻真１２の軸方向の移動位置を規制するように構成されている。すなわち、このオシドリばね２１は、図３および図１０に示すように、その先端部にオシドリ２０の連動ピン２０ｂを弾力的に保持する位置規制部２４が設けられている。   As shown in FIGS. 3 and 10, the mandarin spring 21 is a leaf spring, and is fixed to the base plate 11 at a location located in the vicinity of the mandarin duck 20, and elastically holds the interlocking pin 20 b of the mandarin duck 20 to control the position. By doing so, the rotational position of the mandarin duck 20 is regulated and the axial movement position of the winding stem 12 is regulated. That is, as shown in FIG. 3 and FIG. 10, the mandarin spring 21 is provided with a position restricting portion 24 that elastically holds the interlocking pin 20 b of the mandarin duck 20 at the tip thereof.

この位置規制部２４には、図３および図１０に示すように、連動ピン２０ｂを弾力的に係止する複数の係止凹部が設けられている。これにより、オシドリばね２１は、図３に示すように、巻真１２が押し込まれた第１の位置状態のときに、オシドリ２０の連動ピン２０ｂを位置規制部２４の下部側に位置する係止凹部で弾力的に係止することにより、巻真１２を第１の位置に規制するように構成されている。   As shown in FIGS. 3 and 10, the position restricting portion 24 is provided with a plurality of locking recesses for elastically locking the interlocking pin 20b. As a result, as shown in FIG. 3, the mandarin spring 21 is engaged with the interlocking pin 20 b of the mandarin duck 20 on the lower side of the position restricting portion 24 when the winding stem 12 is in the first position state. The winding stem 12 is configured to be restricted to the first position by being elastically locked by the concave portion.

また、このオシドリばね２１は、図１０に示すように、巻真１２が軸方向に引き出された第２の位置に移動するときに、オシドリ２０が支持軸１７を中心に回転し、これに伴う連動ピン２０ｂの回転移動によって、位置規制部２４が弾性変形し、この弾性変形した位置規制部２４の上部側に位置する係止凹部がオシドリ２０の連動ピン２０ｂを弾力的に係止することにより、巻真１２を第２の位置に規制するように構成されている。   Further, as shown in FIG. 10, when the winding stem 12 moves to the second position where the winding stem 12 is pulled out in the axial direction, the mandatori spring 20 rotates around the support shaft 17, and this is accompanied. Due to the rotational movement of the interlocking pin 20b, the position restricting portion 24 is elastically deformed, and the locking recess located on the upper side of the elastically deformed position restricting portion 24 elastically locks the interlocking pin 20b of the mandarin duck 20. The winding stem 12 is configured to be restricted to the second position.

スイッチ板２２は、図３および図１０に示すように、金属板からなり、オシドリ２０と共に地板１１の支持軸１７に回転可能に取り付けられている。このスイッチ板２２には、後述する回路基板２５の上面に接触して摺動する接触ばね部２２ａが、オシドリ２０の連動アーム部２０ａと反対側に向けて延設されている。このスイッチ板２２の所定箇所には、図３および図１０に示すように、オシドリ２０の連結ピン２０ｃが挿入する挿入孔２２ｂが設けられている。   As shown in FIGS. 3 and 10, the switch plate 22 is made of a metal plate and is attached to the support shaft 17 of the base plate 11 together with the mandarin duck 20 so as to be rotatable. On the switch plate 22, a contact spring portion 22 a that contacts and slides on the upper surface of a circuit board 25 to be described later is extended toward the side opposite to the interlocking arm portion 20 a of the mandarin duck 20. As shown in FIGS. 3 and 10, an insertion hole 22 b into which the connecting pin 20 c of the mandarin duck 20 is inserted is provided at a predetermined position of the switch plate 22.

これにより、スイッチ板２２は、図３および図１０に示すように、接触ばね部２２ａの先端部が回路基板２５の上面に接触した状態で、支持軸１７を中心にオシドリ２０と共に回転移動し、この接触ばね部２２ａの先端部が回路基板２５の上面に設けられた２つの接点部２５ａ、２５ｂに対する接触位置を切り替えるように構成されている。押え板２３は、オシドリばね２１と共に地板１１にねじ２３ａによって取り付けられて、オシドリばね２１およびスイッチ板２２を押え付けることにより、オシドリ２０を地板１１に押し付けるように構成されている。   Thereby, as shown in FIGS. 3 and 10, the switch plate 22 rotates and moves together with the shoreline 20 around the support shaft 17 in a state where the tip of the contact spring portion 22a is in contact with the upper surface of the circuit board 25. The tip of the contact spring portion 22a is configured to switch the contact position with respect to the two contact portions 25a and 25b provided on the upper surface of the circuit board 25. The presser plate 23 is attached to the base plate 11 together with the urchin spring 21 by screws 23 a, and is configured to press the mandarin duck 20 against the base plate 11 by pressing the mandarin spring 21 and the switch plate 22.

ところで、巻真１２にスライド可能に設けられた磁石部材１４は、図４〜図６に示すように、リング状の磁石１８と、この磁石１８を包む樹脂部１９とからなり、全体がほぼ円板状に形成されている。この場合、樹脂部１９には、図４〜図６に示すように、非円形部２６が巻真１２の軸方向における小径の軸部１２ｂ側に向けて突出して設けられている。この非円形部２６は、図６（ａ）および図６（ｂ）に示すように、その外径が磁石１８の外径よりも小さく形成されている共に、断面が四角形状に形成されている。この非円形部２６の左端部には、その外径よりも大きいガイド鍔部２７が設けられている。   By the way, as shown in FIGS. 4 to 6, the magnet member 14 slidably provided on the winding stem 12 includes a ring-shaped magnet 18 and a resin portion 19 that wraps the magnet 18. It is formed in a plate shape. In this case, as shown in FIGS. 4 to 6, the resin portion 19 is provided with a non-circular portion 26 that protrudes toward the small-diameter shaft portion 12 b in the axial direction of the winding stem 12. As shown in FIGS. 6A and 6B, the non-circular portion 26 has an outer diameter smaller than the outer diameter of the magnet 18 and has a square cross section. . At the left end portion of the non-circular portion 26, a guide collar portion 27 larger than the outer diameter is provided.

この磁石部材１４は、図４〜図６に示すように、その中心部に巻真１２の係合軸部１５が挿入する断面四角形状の係合孔１４ａが設けられ、図３および図４に示すように、地板１１に設けられた板ばね２８によって弾力的に押えられている。この板ばね２８は、図３および図４に示すように、巻真１２の軸方向に沿って細長く形成され、磁石部材１４の軸方向における全長に亘って配置され、この状態でばね押え板２９によって押え付けられている。   As shown in FIGS. 4 to 6, the magnet member 14 is provided with an engagement hole 14 a having a quadrangular cross-section into which the engagement shaft portion 15 of the winding stem 12 is inserted, as shown in FIGS. 3 and 4. As shown, it is elastically pressed by a leaf spring 28 provided on the base plate 11. As shown in FIGS. 3 and 4, the leaf spring 28 is formed to be elongated along the axial direction of the winding stem 12 and is disposed over the entire length of the magnet member 14 in the axial direction. It is pressed down by.

また、この板ばね２８には、図７〜図９に示すように、磁石部材１４の非円形部２６の外周に位置して、非円形部２６を外周側から弾力的に挟み付ける一対の弾性片２８ａが設けられている。この一対の弾性片２８ａは、図３に示すように、磁石１８の側面に位置する樹脂部１９とガイド鍔部２７との間に配置され、この状態で磁石部材１４が巻真１２の軸方向への移動を規制するように構成されている。   In addition, as shown in FIGS. 7 to 9, the leaf spring 28 is located on the outer periphery of the non-circular portion 26 of the magnet member 14 and elastically sandwiches the non-circular portion 26 from the outer peripheral side. A piece 28a is provided. As shown in FIG. 3, the pair of elastic pieces 28 a are disposed between the resin portion 19 located on the side surface of the magnet 18 and the guide flange portion 27, and in this state, the magnet member 14 is in the axial direction of the winding stem 12. It is configured to regulate movement to.

これにより、磁石部材１４は、図３および図４に示すように、その中心に設けられた係合孔１４ａに巻真１２の係合軸部１６がスライド可能に挿入し、この状態で巻真１２が軸方向に移動しても、板ばね２８によって弾力的に押えられていることにより、巻真１２に対し相対的に移動して常に一定の位置に保持され、この状態で巻真１２と共に一体的に回転するように構成されている。   Thereby, as shown in FIGS. 3 and 4, the magnet member 14 is slidably inserted into the engagement hole 14a provided at the center thereof, and the winding stem 12 is slid in this state. Even if 12 moves in the axial direction, it is elastically pressed by the leaf spring 28, so that it moves relative to the winding stem 12 and is always held at a fixed position. It is comprised so that it may rotate integrally.

すなわち、この磁石部材１４は、図３および図４に示すように、巻真１２が押し込まれた第１の位置状態のときに、巻真１２の内部側に位置する係合軸部１６の外側の端部側（図４では右側）に位置し、図１０に示すように、巻真１２が引き出された第２の位置状態のときに、巻真１２の内部側に位置する係合軸部１６の内側の先端部側（図４では左側）に位置するように構成されている。   That is, as shown in FIGS. 3 and 4, the magnet member 14 has an outer side of the engaging shaft portion 16 positioned on the inner side of the winding stem 12 when the winding stem 12 is in the first position state. The engagement shaft portion is located on the inner side of the winding stem 12 in the second position state where the winding stem 12 is pulled out as shown in FIG. 16 is configured to be positioned on the inner tip side (the left side in FIG. 4).

また、この磁石部材１４は、巻真１２が押し込まれた第１の位置状態においても、また巻真１２が引き出された第２の位置状態においても、巻真１２と共に一体的に回転し、このときに、図９（ａ）および図９（ｂ）に示すように、非円形部２６が板ばね２８の一対の弾性片２８ａを押し広げるように弾性変形させて乗り越えながら回転することにより、巻真１２に順次クリック感を付与するように構成されている。   The magnet member 14 rotates integrally with the winding stem 12 in the first position state where the winding stem 12 is pushed in and also in the second position state where the winding stem 12 is pulled out. Sometimes, as shown in FIGS. 9A and 9B, the non-circular portion 26 is elastically deformed so as to spread the pair of elastic pieces 28a of the leaf spring 28, and rotates while getting over, thereby winding the winding. It is configured to sequentially provide a click feeling to the true 12.

すなわち、この磁石部材１４の非円形部２６は、断面四角形状に形成されていることにより、磁石部材１４が巻真１２と共に一体的に回転する際に、図９（ａ）に示すように、非円形部２６の角部が板ばね２８の一対の弾性片２８ａを押し広げ、図９（ｂ）に示すように、非円形部２６が板ばね２８の一対の弾性片２８ａを乗り越えると、板ばね２８の一対の弾性片２８ａが互いに接近する方向に弾性復帰して非円形部２６の辺部を挟み付けるように弾性変形することにより、巻真１２にクリック感を付与するように構成されている。   That is, since the non-circular portion 26 of the magnet member 14 is formed in a quadrangular cross section, when the magnet member 14 rotates integrally with the winding stem 12, as shown in FIG. When the corners of the non-circular portion 26 spread the pair of elastic pieces 28a of the leaf spring 28 and the non-circular portion 26 gets over the pair of elastic pieces 28a of the leaf spring 28 as shown in FIG. The pair of elastic pieces 28a of the spring 28 are elastically deformed so as to elastically return in a direction approaching each other and sandwich the side portion of the non-circular portion 26, thereby providing a click feeling to the winding stem 12. Yes.

これにより、非円形部２６は、巻真１２が連続して回転して非円形部２６が連続回転すると、その連続回転に伴って、非円形部２６の角部が板ばね２８の一対の弾性片２８ａを順次弾性変形させて順次乗り越えることにより、巻真１２の連続回転に応じて、巻真１２に順次クリック感を付与するように構成されている。   As a result, when the winding stem 12 rotates continuously and the non-circular portion 26 continuously rotates, the non-circular portion 26 causes the corners of the non-circular portion 26 to have a pair of elastic springs 28. By sequentially elastically deforming the pieces 28a and overcoming them, the click stem 12 is configured to be sequentially clicked according to the continuous rotation of the wind stem 12.

一方、磁気センサ１５は、図１、図２および図４に示すように、地板１１の裏面（図４では下面）に設けられた回路基板２５の下面における磁石部材１４と対応する箇所に設けられている。これにより、磁気センサ１５は、回路基板２５を間に挟んで磁石部材１４と対応している。   On the other hand, the magnetic sensor 15 is provided at a position corresponding to the magnet member 14 on the lower surface of the circuit board 25 provided on the back surface (the lower surface in FIG. 4) of the ground plane 11 as shown in FIGS. 1, 2, and 4. ing. Thus, the magnetic sensor 15 corresponds to the magnet member 14 with the circuit board 25 interposed therebetween.

この磁気センサ１５は、２つの磁気検出素子、例えば２つの磁気抵抗素子（ＭＲ素子：Magneto Resistance 素子）と、その出力をデジタル化するＩＣとを１つのパッケージに収めたものであり、２つの磁気抵抗素子で磁石部材１４の回転に伴う磁界の変化を検出して、高い（ハイ：Ｈ）、低い（ロウ：Ｌ）の２種類の検出信号を出力するように構成されている。   The magnetic sensor 15 includes two magnetic detection elements, for example, two magnetoresistive elements (MR elements) and an IC for digitizing the output in one package. The resistance element detects a change in the magnetic field accompanying the rotation of the magnet member 14, and outputs two types of detection signals, high (high: H) and low (low: L).

すなわち、この磁気センサ１５は、２つの磁気抵抗素子の設置位置が異なっていることにより、磁石部材１４の回転に伴う磁界の変化を検出した際に、その出力に位相差が生じ、この位相差によって２種類の検出信号を出力することにより、磁石部材１４の回転を検出するように構成されている。この場合、回路基板２５に設けられたマイコン（図示せず）は、２種類の検出信号を解析して、磁石部材１４の回転角度を算出する。   That is, when the magnetic sensor 15 detects the change in the magnetic field accompanying the rotation of the magnet member 14 due to the difference in the installation positions of the two magnetoresistive elements, a phase difference is generated in the output, and this phase difference The rotation of the magnet member 14 is detected by outputting two types of detection signals. In this case, a microcomputer (not shown) provided on the circuit board 25 analyzes the two types of detection signals and calculates the rotation angle of the magnet member 14.

また、この磁気センサ１５は、磁石部材１４の回転方向（正回転であるか逆回転であるか）を検出すると共に、磁石部材１４の正回転または逆回転が連続しているか否かをも検出する。これにより、回路基板２５に設けられたマイコンは、磁気センサ１５で検出された回転方向の検出信号により、指針を正方向（時計回り）または逆方向（反時計回り）に回転させると共に、磁気センサ１５で検出された磁石部材１４の回転が連続しているか否かの検出信号により、回転が連続している場合に、指針を早送りで正方向（時計回り）または逆方向（反時計回り）に回転させる。   The magnetic sensor 15 detects the rotation direction of the magnet member 14 (whether forward rotation or reverse rotation), and also detects whether the forward rotation or reverse rotation of the magnet member 14 is continuous. To do. Thereby, the microcomputer provided on the circuit board 25 rotates the pointer in the forward direction (clockwise) or the reverse direction (counterclockwise) based on the rotation direction detection signal detected by the magnetic sensor 15, and the magnetic sensor. When the rotation of the magnet member 14 detected at 15 is continued, the pointer is fast-forwarded in the forward direction (clockwise) or the reverse direction (counterclockwise). Rotate.

また、この磁気センサ１５は、図１０に示すように、巻真１２が引き出されて位置規制部材１３のスイッチ板２２が回転し、このスイッチ板２２の接触ばね部２２ａが、回路基板２５に設けられた左側に位置する他方の接点部２５ｂに接触して、通常運針状態から時刻修正状態に切り替わった際に、オン状態となり、磁石部材１４の磁石１８の磁界を検出するように構成されている。   Further, as shown in FIG. 10, the magnetic sensor 15 has the winding stem 12 pulled out to rotate the switch plate 22 of the position restricting member 13, and the contact spring portion 22 a of the switch plate 22 is provided on the circuit board 25. It is configured to detect the magnetic field of the magnet 18 of the magnet member 14 when it contacts the other contact portion 25b located on the left side and is switched from the normal hand movement state to the time correction state. .

この場合、磁気センサ１５は、図３に示すように、巻真１２が押し込まれて位置規制部材１３のスイッチ板２２の接触ばね部２２ａが、回路基板２５に設けられた右側に位置する一方の接点部２５ａに接触して、時計回路（図示せず）がオン状態になり、通常運針状態であるときには、オフ状態となり、磁石部材１４の磁石１８の磁界を検出しないように構成されている。   In this case, as shown in FIG. 3, the magnetic sensor 15 is configured such that the winding stem 12 is pushed in and the contact spring portion 22 a of the switch plate 22 of the position regulating member 13 is located on the right side provided on the circuit board 25. When the timepiece circuit (not shown) is in an on state in contact with the contact portion 25a and is in a normal hand movement state, it is in an off state and is configured not to detect the magnetic field of the magnet 18 of the magnet member 14.

また、この磁気センサ１５の周囲には、図１、図２および図４に示すように、耐磁板３０が配置されている。この耐磁板３０は、磁性材料からなり、腕時計ケース１の外部からの磁界を吸収するためのものであり、全体が枠状に形成され、回路基板２５に半田３１によって取り付けられている。これにより、磁気センサ１５は、耐磁板３０によって外部磁界の影響を受けずに、磁石部材１４の回転磁界を感度良く正確に検出するように構成されている。   Further, as shown in FIGS. 1, 2, and 4, a magnetic-resistant plate 30 is disposed around the magnetic sensor 15. The magnetic plate 30 is made of a magnetic material and absorbs a magnetic field from the outside of the watch case 1. The magnetic plate 30 is entirely formed in a frame shape and is attached to the circuit board 25 with solder 31. Thereby, the magnetic sensor 15 is configured to detect the rotating magnetic field of the magnet member 14 accurately and accurately without being influenced by the external magnetic field by the magnetic-resistant plate 30.

次に、この電子腕時計における時刻修正装置６の作用について説明する。
まず、巻真１２を軸方向に押し込んで第１の位置に移動させると、図３および図４に示すように、巻真１２の段差凹部１２ａが時計モジュール４の内部側（図４では左側）に移動し、巻真１２の係合軸部１６が図４に示す矢印Ｘ方向に押し込まれる。この状態では、磁石部材１４が板ばね２８で押えられているので、巻真１２が押し込まれても、磁石部材１４は巻真１２と共に移動せず、巻真１２の係合軸部１６における外側の端部側（図４では右側）に位置して、磁気センサ１５に対応している。 Next, the operation of the time adjustment device 6 in this electronic wristwatch will be described.
First, when the winding stem 12 is pushed in the axial direction and moved to the first position, as shown in FIGS. 3 and 4, the stepped recess 12a of the winding stem 12 is located on the inner side of the timepiece module 4 (left side in FIG. 4). 4 and the engaging shaft portion 16 of the winding stem 12 is pushed in the direction of the arrow X shown in FIG. In this state, since the magnet member 14 is pressed by the leaf spring 28, the magnet member 14 does not move with the winding stem 12 even when the winding stem 12 is pushed in, and the outer side of the winding stem 12 at the engagement shaft portion 16. And corresponds to the magnetic sensor 15.

また、このときには、巻真１２の段差凹部１２ａが時計モジュール４の内部側に移動するので、図３に示すように、オシドリ２０の連動アーム部２０ａが時計モジュール４の内部側（図３では右側）に向けて移動し、オシドリ２０が支持軸１７を中心に反時計回りに回転する。これに伴って、図３に示すように、連動ピン２０ａがオシドリばね２１に設けられた位置規制部２４の下部側に位置する係止凹部に弾力的に保持される。これにより、巻真１２が押し込まれた第１の位置に規制される。   At this time, the step recess 12a of the winding stem 12 moves to the inside of the timepiece module 4, so that the interlocking arm portion 20a of the mandarin duck 20 moves to the inside of the timepiece module 4 (on the right side in FIG. 3), as shown in FIG. ) And the mandarin duck 20 rotates counterclockwise around the support shaft 17. Along with this, as shown in FIG. 3, the interlocking pin 20 a is elastically held in the locking recess located on the lower side of the position restricting portion 24 provided in the shorebird spring 21. Thereby, the winding stem 12 is regulated to the first position where it is pushed.

また、このときには、スイッチ板２２がオシドリ２０の連結ピン２０ｃによってオシドリ２０と連結されているので、図３に示すように、スイッチ板２２が支持軸１７を中心にオシドリ２０と共に時計回りに回転する。これにより、スイッチ板２２における接触ばね部２２ａの先端部が、図３に示すように、回路基板２５の上面に接触した状態で回転移動する。   At this time, since the switch plate 22 is connected to the mandarin duck 20 by the connecting pin 20c of the mandarin duck 20, the switch plate 22 rotates clockwise together with the mandarin duck 20 around the support shaft 17, as shown in FIG. . As a result, the tip of the contact spring portion 22a of the switch plate 22 rotates and moves in contact with the upper surface of the circuit board 25 as shown in FIG.

これにより、接触ばね部２２ａが、図３に示すように、回路基板２５に設けられた右側に位置する一方の接点部２５ａに接触し、時計回路をオン状態にして、通常運針状態にする。このときには、磁気センサ１５がオフ状態になり、磁気センサ１５による磁気検出が停止されている。これにより、巻真１２を回転させて磁石部材１４を回転させても、磁気センサ１５が磁石部材１４の回転磁界を検出しない。   As a result, as shown in FIG. 3, the contact spring portion 22 a comes into contact with one contact portion 25 a located on the right side provided on the circuit board 25, turns on the timepiece circuit, and sets the normal hand movement state. At this time, the magnetic sensor 15 is turned off, and the magnetic detection by the magnetic sensor 15 is stopped. Thereby, even if the winding stem 12 is rotated to rotate the magnet member 14, the magnetic sensor 15 does not detect the rotating magnetic field of the magnet member 14.

一方、巻真１２が軸方向に引き出されて第２の位置に移動すると、図１０に示すように、巻真１２の段差凹部１２ａが時計モジュール４の外側に向けて移動し、巻真１２の係合軸部１６が引出し方向（図１０に矢印Ｙで示す右方向)に移動する。このときにも、磁石部材１４が板ばね２８で押えられているので、巻真１２が引出し方向に移動しても、磁石部材１４は巻真１２と共に移動せず、巻真１２の係合軸部１６における内側の先端部側（図１０では左側）に位置する。   On the other hand, when the winding stem 12 is pulled out in the axial direction and moved to the second position, the step recess 12a of the winding stem 12 moves toward the outside of the timepiece module 4 as shown in FIG. The engagement shaft portion 16 moves in the drawing direction (right direction indicated by an arrow Y in FIG. 10). Also at this time, since the magnet member 14 is pressed by the leaf spring 28, the magnet member 14 does not move with the winding stem 12 even if the winding stem 12 moves in the pull-out direction, and the engaging shaft of the winding stem 12 does not move. It is located on the inner tip side of the portion 16 (left side in FIG. 10).

また、このときには、図１０に示すように、巻真１２の段差凹部１２ａが時計モジュール４の外側（図１０では右側）に向けて移動するので、オシドリ２０の連動アーム部２０ａが時計モジュール４の外側に向けて移動し、オシドリ２０が支持軸１７を中心に時計回りに回転する。これに伴って、図１０に示すように、連動ピン２０ａがオシドリばね２１に設けられた位置規制部２４の上部側に位置する係止凹部に弾力的に保持される。これにより、巻真１２が引き出された第２の位置に規制される。   At this time, as shown in FIG. 10, the step recess 12 a of the winding stem 12 moves toward the outside of the timepiece module 4 (right side in FIG. 10), so that the interlocking arm portion 20 a of the mandarin duck 20 is attached to the timepiece module 4. It moves toward the outside, and the mandarin duck 20 rotates clockwise around the support shaft 17. Along with this, as shown in FIG. 10, the interlocking pin 20 a is elastically held in the locking recess located on the upper side of the position restricting portion 24 provided in the mandarin spring 21. Thereby, the winding stem 12 is regulated to the second position where it is pulled out.

このときにも、スイッチ板２２がオシドリ２０の連結ピン２０ｃによってオシドリ２０と連結されているので、図１０に示すように、スイッチ板２２が支持軸１７を中心にオシドリ２０と共に時計回りに回転する。これにより、スイッチ板２２の接触ばね部２２ａの先端部が、回路基板２５に接触した状態で上記とは逆方向に回転移動する。これにより、図１０に示すように、回路基板２５に設けられた左側に位置する他方の接点部２５ｂに移動して接触し、磁気センサ１５をオン状態にして、磁気センサ１５による磁気検出を可能な状態にする。   Also at this time, since the switch plate 22 is connected to the mandarin duck 20 by the connecting pin 20c of the mandarin duck 20, the switch plate 22 rotates clockwise with the mandarin duck 20 about the support shaft 17, as shown in FIG. . As a result, the tip end portion of the contact spring portion 22a of the switch plate 22 rotates and moves in a direction opposite to the above in a state where the tip end portion is in contact with the circuit board 25. As a result, as shown in FIG. 10, the magnetic sensor 15 is turned on by moving to the other contact portion 25 b located on the left side provided on the circuit board 25, and magnetic detection by the magnetic sensor 15 is possible. To make sure

この状態で巻真１２を回転させると、磁石部材１４が巻真１２と共に回転して磁界が変化し、この回転する磁界の変化を磁気センサ１５が検出する。この磁気センサ１５で出力された検出信号は、回路基板２５のマイコンで解析されて、巻真１２の回転に応じて指針（図示せず）を運針させて時刻を修正する。このときには、磁気センサ１５が磁石部材１４の回転方向（正回転であるか逆回転であるか）をも検出し、指針を正方向（時計回り）または逆方向（反時計回り）に運針させて時刻を修正する。   When the winding stem 12 is rotated in this state, the magnet member 14 rotates with the winding stem 12 to change the magnetic field, and the magnetic sensor 15 detects the change in the rotating magnetic field. The detection signal output from the magnetic sensor 15 is analyzed by the microcomputer of the circuit board 25, and the time is corrected by moving a pointer (not shown) according to the rotation of the winding stem 12. At this time, the magnetic sensor 15 also detects the rotation direction of the magnet member 14 (forward rotation or reverse rotation), and moves the pointer in the forward direction (clockwise) or the reverse direction (counterclockwise). Correct the time.

また、このときには、磁石部材１４が巻真１２と共に回転すると、磁石部材１４の非円形部２６が、巻真１２と共に一体的に回転するので、図９（ａ）に示すように、非円形部２６の角部が板ばね２８の一対の弾性片２８ａを押し広げて乗り越えることにより、巻真１２にクリック感が付与され、これにより巻真１２の回転状態を感覚的に知ることができるので、巻真１２を良好に回転操作することができる。   At this time, when the magnet member 14 rotates together with the winding stem 12, the non-circular portion 26 of the magnet member 14 rotates integrally with the winding stem 12, so that as shown in FIG. Since the corners of 26 push the pair of elastic pieces 28a of the leaf spring 28 to spread over, a click feeling is imparted to the winding stem 12, so that the rotation state of the winding stem 12 can be sensuously known. The winding stem 12 can be rotated favorably.

この場合、磁石部材１４の正回転または逆回転が連続していることを磁気センサ１５が検出した場合には、指針を早送りで正方向（時計回り）または逆方向（反時計回り）に運針させて、速やかに時刻を修正する。このときにも、巻真１２の連続回転に伴って非円形部２６が連続回転するので、その連続回転に伴って、非円形部２６の角部が板ばね２８の一対の弾性片２８ａを順次弾性変形させて順次乗り越える。   In this case, when the magnetic sensor 15 detects that the magnet member 14 is continuously rotating in the forward or reverse direction, the needle is moved in the forward direction (clockwise) or the reverse direction (counterclockwise) by fast-forwarding. To correct the time promptly. Also at this time, since the non-circular portion 26 continuously rotates with the continuous rotation of the winding stem 12, the corner portion of the non-circular portion 26 sequentially moves the pair of elastic pieces 28a of the leaf spring 28 with the continuous rotation. Get over the elastically deformed one by one.

このため、巻真１２の連続回転に応じて、巻真１２に順次クリック感が付与されるので、このときにも巻真１２の連続回転状態を感覚的に知ることができ、これにより巻真１２を良好に回転操作することができる。また、巻真１２が引き出された第２の位置で、巻真１２が数十秒の間、回転操作されないときには、磁気センサ１５をオフ状態にして、電力の消費を防ぐ。   For this reason, since the click feeling is sequentially given to the winding stem 12 according to the continuous rotation of the winding stem 12, the continuous rotation state of the winding stem 12 can also be sensibly known at this time, thereby 12 can be rotated well. Further, when the winding stem 12 is not rotated for several tens of seconds at the second position where the winding stem 12 is pulled out, the magnetic sensor 15 is turned off to prevent power consumption.

このように、この電子腕時計によれば、回転方向に操作可能な操作部材である巻真１２と、この巻真１２に取り付けられて巻真１２と一体的に回転する磁石部材１４と、この磁石部材１４の回転磁界を検出する磁気センサ１５と、磁石部材１４に設けられて断面形状が非円形状に形成された非円形部２６と、この非円形部２６に弾接し、巻真１２を回転させた際に非円形部２６によって弾性変形して非円形部２６が乗り越える板ばね２８とを備えているので、巻真１２にクリック感を付与することができる。   As described above, according to the electronic wristwatch, the winding stem 12 which is an operation member operable in the rotation direction, the magnet member 14 attached to the winding stem 12 and rotating integrally with the winding stem 12, and the magnet A magnetic sensor 15 for detecting a rotating magnetic field of the member 14, a non-circular portion 26 provided on the magnet member 14 and having a non-circular cross-sectional shape, and elastically contacting the non-circular portion 26 to rotate the winding stem 12. Since a leaf spring 28 is provided that is elastically deformed by the non-circular portion 26 when the non-circular portion 26 is moved over, the click stem 12 can be given a click feeling.

すなわち、この電子腕時計では、巻真１２を回転させて磁石部材１４を巻真１２と一体的に回転させると、この磁石部材１４の回転磁界を磁気センサ１５で検出することができると共に、巻真１２が回転すると、非円形部２６も回転し、この非円形部２６が板ばね２８を弾性変形させて乗り越えるので、巻真１２にクリック感を付与することができる。このため、巻真１２を回転させた際に、その巻真１２の回転状態を感覚的に知ることができるので、巻真１２の回転操作性を向上させることができる。   That is, in this electronic wristwatch, when the winding stem 12 is rotated and the magnet member 14 is rotated integrally with the winding stem 12, the rotating magnetic field of the magnet member 14 can be detected by the magnetic sensor 15, and the winding stem When 12 rotates, the non-circular portion 26 also rotates, and this non-circular portion 26 elastically deforms the leaf spring 28 and gets over, so that a click feeling can be imparted to the winding stem 12. For this reason, when the winding stem 12 is rotated, the rotational state of the winding stem 12 can be known sensuously, so that the rotational operability of the winding stem 12 can be improved.

この場合、板ばね２８は、磁石部材１４の非円形部２６を弾力的に挟み付ける一対の弾接片２８ａを備えているので、この一対の弾性片２８ａによって弾力的に非円形部２６を確実に且つ良好に挟み付けることができ、これにより巻真１２と共に非円形部２６が回転する際に、非円形部２６が一対の弾性片２８ａを押し広げて乗り越えることにより、巻真１２にクリック感を確実に且つ良好に付与することができる。   In this case, the leaf spring 28 includes a pair of elastic contact pieces 28a for elastically sandwiching the non-circular portion 26 of the magnet member 14, so that the non-circular portion 26 is elastically secured by the pair of elastic pieces 28a. Thus, when the non-circular portion 26 rotates together with the winding stem 12, the non-circular portion 26 pushes over the pair of elastic pieces 28a and gets over, so that the winding stem 12 has a click feeling. Can be reliably and satisfactorily imparted.

この場合、巻真１２が連続して回転し、これに伴って非円形部２６が連続回転する際には、その連続回転に伴って、非円形部２６が一対の弾性片２８ａを順次弾性変形させて順次乗り越えることにより、巻真１２の連続回転に応じて、巻真１２に順次クリック感を付与することができ、これにより巻真１２の連続回転状態を感覚的に知ることができる。   In this case, when the winding stem 12 is continuously rotated and the non-circular portion 26 is continuously rotated accordingly, the non-circular portion 26 sequentially elastically deforms the pair of elastic pieces 28a along with the continuous rotation. By sequentially overcoming the winding stem 12, it is possible to give a click feeling to the winding stem 12 in accordance with the continuous rotation of the winding stem 12, so that the continuous rotation state of the winding stem 12 can be sensed.

また、この電子腕時計によれば、磁石部材１４が、磁界を発生する磁石１８と、この磁石１８を包み込む樹脂部１９とを備え、この樹脂部１９に非円形部２６が設けられていることにより、樹脂部１９を成形するときに、これと同時に非円形部２６を容易に且つ簡単に形成することができると共に、非円形部２６を磁石部材１４と共に巻真１２に組み付けることができる。   According to this electronic wristwatch, the magnet member 14 includes the magnet 18 that generates a magnetic field and the resin portion 19 that wraps the magnet 18, and the resin portion 19 is provided with the non-circular portion 26. When the resin portion 19 is molded, the non-circular portion 26 can be easily and easily formed at the same time, and the non-circular portion 26 can be assembled to the winding stem 12 together with the magnet member 14.

この場合、非円形部２６は、その外径が磁石１８の外径よりも小さく、且つ磁石１８の側面に位置する樹脂部１９とガイド鍔部２７との間に位置し、この状態で板ばね２８の一対の弾性片２８ａに挟まれているので、この一対の弾性片２８ａによって非円形部２６を磁石部材１４と共に位置規制することができる。   In this case, the non-circular portion 26 has an outer diameter smaller than the outer diameter of the magnet 18 and is positioned between the resin portion 19 and the guide flange portion 27 located on the side surface of the magnet 18. Since the pair of elastic pieces 28 a are sandwiched between the pair of elastic pieces 28 a, the position of the non-circular portion 26 together with the magnet member 14 can be regulated by the pair of elastic pieces 28 a.

また、この電子腕時計によれば、巻真１２の断面非円形の係合軸部１６が磁石部材１４の係合孔１８ａに係合しているので、巻真１２を軸方向に移動操作する際に、磁石部材１４を巻真１２に対して相対的に移動させることができると共に、非円形部２６を弾力的に挟む一対の弾性片２８ａによって磁石部材１４が軸方向の位置が規制されているので、これにより磁石部材１４を巻真１２の軸方向に対して常に一定の位置に保持することができる。   Further, according to this electronic wristwatch, since the engaging shaft portion 16 having a non-circular cross section of the winding stem 12 is engaged with the engaging hole 18a of the magnet member 14, when the winding stem 12 is moved and operated in the axial direction, Further, the magnet member 14 can be moved relative to the winding stem 12, and the axial position of the magnet member 14 is regulated by a pair of elastic pieces 28a that elastically sandwich the non-circular portion 26 therebetween. As a result, the magnet member 14 can always be held at a fixed position with respect to the axial direction of the winding stem 12.

このため、巻真１２を軸方向に移動操作しても、巻真１２や磁石部材１４を破損せずに、常に磁石部材１４を磁気センサ１５に対応させることができるので、巻真１２を軸方向における複数の位置に移動させても、１つの磁気センサ１５で巻真１２の回転を正確に検出することができるほか、磁気センサ１５が磁石部材１４に対して非接触状態であるから、耐久性の高いものを提供することができる。   For this reason, even if the winding stem 12 is moved in the axial direction, the magnet member 14 can always correspond to the magnetic sensor 15 without damaging the winding stem 12 and the magnet member 14, so that the winding stem 12 can be Even if it is moved to a plurality of positions in the direction, the rotation of the winding stem 12 can be accurately detected by one magnetic sensor 15, and the magnetic sensor 15 is in a non-contact state with respect to the magnet member 14, so that it is durable. High quality can be provided.

この場合、磁気センサ１５は、磁石部材１４の回転を検出して検出信号を出力し、この出力された検出信号が回路基板２５のマイコンで解析されて、巻真１２の回転に応じて指針（図示せず）を運針させて時刻を修正することができる。このときには、磁気センサ１５が磁石部材１４の回転方向（正回転であるか逆回転であるか）を検出するので、指針を正方向（時計回り）または逆方向（反時計回り）に回転させることができる。   In this case, the magnetic sensor 15 detects the rotation of the magnet member 14 and outputs a detection signal. The output detection signal is analyzed by the microcomputer of the circuit board 25, and the pointer ( The time can be corrected by moving the hand (not shown). At this time, since the magnetic sensor 15 detects the rotation direction of the magnet member 14 (whether it is forward rotation or reverse rotation), the pointer is rotated in the forward direction (clockwise) or the reverse direction (counterclockwise). Can do.

また、このとき、磁石部材１４の正回転または逆回転が連続しているか否かを磁気センサ１５で検出することにより、回転が連続している場合に、指針を早送りで正方向（時計回り）または逆方向（反時計回り）に回転させて、速やかに時刻を修正することができる。この場合、磁気センサ１５は、耐磁板３０によって囲われているので、腕時計ケース１の外部磁界の影響を受けず、磁石部材１４の磁界を正確に検出することができる。   At this time, the magnetic sensor 15 detects whether the magnet member 14 is continuously rotating in the forward or reverse direction. When the rotation is continued, the pointer is fast-forwarded in the forward direction (clockwise). Alternatively, the time can be quickly corrected by rotating in the reverse direction (counterclockwise). In this case, since the magnetic sensor 15 is surrounded by the magnetic-resistant plate 30, it is possible to accurately detect the magnetic field of the magnet member 14 without being affected by the external magnetic field of the wristwatch case 1.

また、この電子腕時計では、巻真１２をその軸方向における第１の位置と第２の位置とに位置規制する位置規制部材１３を備えているので、巻真１２をその軸方向における第１の位置と第２の位置とに正確に且つ確実に位置規制することができる。すなわち、位置規制部材１３は、巻真１２の軸方向への移動に伴って回転するオシドリ２０と、このオシドリ２０の連動ピンを位置規制部２４の複数の係止凹部によって弾力的に保持するオシドリばね２１とを備えているので、オシドリばね２１の位置規制部２４によってオシドリ２０の回転位置を規制することができ、これにより巻真１２の軸方向における位置を確実に規制することができる。   In addition, since the electronic wristwatch includes the position restricting member 13 that restricts the winding stem 12 to the first position and the second position in the axial direction, the winding stem 12 has the first axial direction in the axial direction. The position can be accurately and reliably restricted to the position and the second position. That is, the position restricting member 13 is a mandarin duck 20 that rotates with the movement of the winding stem 12 in the axial direction, and a mandarin duck that elastically holds the interlocking pin of the mandarin duck 20 by a plurality of locking recesses of the position restricting portion 24. Since the spring 21 is provided, the rotational position of the mandarin duck 20 can be restricted by the position restricting portion 24 of the mandarin spring 21, whereby the position of the winding stem 12 in the axial direction can be reliably restricted.

また、巻真１２は、その軸方向に押し込まれた第１の位置と引き出された第２の位置とで、回路基板２５の接点部２５ａ、２５ｂを切り替える接点切替部材であるスイッチ板２２を備えているので、磁石部材１４が磁気センサ１５に常に対応していても、スイッチ板２２で回路基板２５の接点部２５ａ、２５ｂを切り替えることにより、磁気センサ１５をオン状態とオフ状態とに切り替えることができる。   Further, the winding stem 12 includes a switch plate 22 which is a contact switching member for switching the contact portions 25a and 25b of the circuit board 25 between the first position pushed in the axial direction and the second position pulled out. Therefore, even if the magnet member 14 always corresponds to the magnetic sensor 15, the magnetic sensor 15 is switched between the on state and the off state by switching the contact portions 25 a and 25 b of the circuit board 25 with the switch plate 22. Can do.

すなわち、スイッチ板２２は、巻真１２の軸方向への移動に伴って回転するオシドリ２０と共に回転して、接触ばね部２２ａが回路基板２５に設けられた２つの接点部２５ａ、２５ｂを切り替えることができるので、巻真１２が押し込まれた第１の位置のときに、接触ばね部２２ａが回路基板２５に設けられた右側に位置する一方の接点部２５ａに接触して、磁気センサ１５をオフ状態にし、また巻真１２が引き出された第２の位置のときに、接触ばね部２２ａが回路基板２５に設けられた左側に位置する他方の接点部２５ｂに接触して、磁気センサ１５をオン状態にすることができる。   That is, the switch plate 22 rotates together with the mandarin duck 20 that rotates as the winding stem 12 moves in the axial direction, and the contact spring portion 22 a switches between the two contact portions 25 a and 25 b provided on the circuit board 25. Therefore, at the first position where the winding stem 12 is pushed in, the contact spring portion 22a comes into contact with one contact portion 25a located on the right side provided on the circuit board 25, and the magnetic sensor 15 is turned off. In the second position where the winding stem 12 is pulled out, the contact spring portion 22a comes into contact with the other contact portion 25b located on the left side provided on the circuit board 25, and the magnetic sensor 15 is turned on. Can be in a state.

このため、巻真１２が押し込まれた第１の位置のときには、磁気センサ１５がオフ状態であるから、磁気センサ１５に対する待機電流を防ぐことができると共に、この状態で巻真１２を回転させて磁石部材１４を回転させても、磁気センサ１５によって磁石部材１４の回転を検出することがないので、磁気センサ１５による消費電力を低減することができる。   For this reason, when the winding stem 12 is in the first position, the magnetic sensor 15 is in the OFF state, so that standby current for the magnetic sensor 15 can be prevented and the winding stem 12 is rotated in this state. Even if the magnet member 14 is rotated, the rotation of the magnet member 14 is not detected by the magnetic sensor 15, so that power consumption by the magnetic sensor 15 can be reduced.

また、巻真１２が引き出された第２の位置のときには、磁気センサ１５がオン状態になるので、巻真１２を回転させて磁石部材１４を回転させると、磁気センサ１５で磁石部材１４の回転を検出することができる。この場合、巻真１２が引き出された第２の位置のときに、数十秒の間、巻真１２が回転操作されないときには、磁気センサ１５をオフ状態にするので、これによっても磁気センサ１５による消費電力を抑えて、低消費電力化を図ることができる。   Further, when the winding stem 12 is at the second position where the winding stem 12 is pulled out, the magnetic sensor 15 is turned on. Therefore, when the winding stem 12 is rotated and the magnet member 14 is rotated, the magnetic sensor 15 rotates the magnet member 14. Can be detected. In this case, when the winding stem 12 is not rotated for several tens of seconds at the second position where the winding stem 12 is pulled out, the magnetic sensor 15 is turned off. It is possible to reduce power consumption by suppressing power consumption.

なお、上述した実施形態では、磁石部材１４の樹脂部１９に設けられた非円形部２６が断面四角形状に形成されている場合にいて述べたが、これに限らず、非円形部は、例えば断面形状が三角形状であっても良く、また断面形状が五角形、六角形などの多角形状でも良く、さらに断面形状が楕円形状であっても良い。   In the above-described embodiment, the case where the non-circular portion 26 provided in the resin portion 19 of the magnet member 14 is formed in a quadrangular cross-section has been described.

また、上述した実施形態では、板ばね２８に一対の弾性片２８ａを設け、この一対の弾性片２８ａで磁石部材１４の樹脂部１９に設けられた非円形部２６を弾力的に挟むように構成した場合について述べたが、必ずしも一対の弾性片２８ａで非円形部２６を弾力的に挟む必要はなく、弾性片を片側のみに設け、この片側の弾性片のみを非円形部２６の外周面に弾接させた構成でも良い。   In the above-described embodiment, the pair of elastic pieces 28a is provided on the leaf spring 28, and the non-circular portion 26 provided on the resin portion 19 of the magnet member 14 is elastically sandwiched between the pair of elastic pieces 28a. However, it is not always necessary to elastically sandwich the non-circular portion 26 between the pair of elastic pieces 28a. The elastic piece is provided only on one side, and only the elastic piece on one side is provided on the outer peripheral surface of the non-circular portion 26. It may be configured to be elastically contacted.

また、上述した実施形態では、磁石部材１４の樹脂部１９を軸方向に突出させ、この突出した樹脂部１９に非円形部２６を設けた場合について述べたが、これに限らず、例えば樹脂部１９を磁石１８の外周面よりも外周方向に突出させ、この突出した樹脂部１９の外周を非円形状に形成することにより、磁石１８の外周面よりも外周方向に突出する非円形部を設けた構成であっても良い。   In the above-described embodiment, the case where the resin portion 19 of the magnet member 14 is protruded in the axial direction and the non-circular portion 26 is provided on the protruded resin portion 19 is not limited thereto. For example, the resin portion 19 is protruded in the outer peripheral direction from the outer peripheral surface of the magnet 18, and the outer periphery of the protruding resin portion 19 is formed in a non-circular shape, thereby providing a non-circular portion that protrudes in the outer peripheral direction from the outer peripheral surface of the magnet 18. The structure may be different.

また、これに限らず、巻真１２に非円形部を設け、この非円形部の外周に板ばね２６の一部を弾接させた構成でも良い。このように構成しても、巻真１２の回転によって非円形部が板ばね２６の一部を弾性変形させて乗り越えることにより、巻真１２にクリック感を良好に付与することができる。   Further, the present invention is not limited to this, and a configuration in which a non-circular portion is provided in the winding stem 12 and a part of the leaf spring 26 is elastically contacted with the outer periphery of the non-circular portion may be employed. Even if comprised in this way, a non-circular part elastically deforms a part of leaf | plate spring 26 and gets over by rotation of the winding stem 12, and can give a click feeling favorably to the winding stem 12. FIG.

また、上述した実施形態では、巻真１２に断面四角形状の係合軸部１６を設け、磁石部材１４の中心部に巻真１２の係合軸部１６が挿入する四角形状の係合孔１４ａを設けた場合について述べたが、これに限らず、巻真１２の係合軸部１６および磁石部材１４の係合孔１４ａの各断面形状を、三角形、五角形、六角形などの多角形状、または楕円形状、スプライン形状などの非円形状に形成しても良い。   Further, in the above-described embodiment, the engagement stem portion 16 having a quadrangular cross section is provided in the winding stem 12, and the rectangular engagement hole 14 a into which the engagement shaft portion 16 of the winding stem 12 is inserted in the center portion of the magnet member 14.

さらに、上述した実施形態では、巻真１２がその軸方向における第１の位置と第２の位置とに移動するように構成された場合について述べたが、必ずしも第１、第２の各位置のみに移動する構成である必要はなく、第２の位置から更に引き出された第３の位置にも移動するように構成しても良い。このように構成しても、磁石部材１４を板ばね２６によって押え付けることにより、巻真１２の軸方向への引出し操作に応じて磁石部材１４が移動することがなく、常に磁石部材１４が１つの磁気センサ１５に対応するので、この１つの磁気センサ１５で巻真１２の回転を検出することができる。   Further, in the above-described embodiment, the case where the winding stem 12 is configured to move to the first position and the second position in the axial direction has been described. However, only the first and second positions are necessarily described. It is not necessary to be configured to move to the third position, and it may be configured to move to a third position further drawn from the second position. Even in this configuration, by pressing the magnet member 14 with the leaf spring 26, the magnet member 14 does not move in accordance with the pulling operation of the winding stem 12 in the axial direction, and the magnet member 14 is always 1 Since it corresponds to one magnetic sensor 15, the rotation of the winding stem 12 can be detected by this one magnetic sensor 15.

なおまた、上述した実施形態およびその各変形例では、指針式の電子腕時計に適用した場合について述べたが、必ずしも電子腕時計である必要はなく、例えばトラベルウオッチ、目覚まし時計、置き時計、掛け時計などの各種の電子時計に適用することができるほか、必ずしも電子時計に限らず、携帯電話機やＰＤＡ（パーソナル・デジタル・アシスタント）などの電子機器にも広く適用することができる。   In addition, in the above-described embodiment and each modification thereof, the case where it is applied to a pointer-type electronic wristwatch has been described, but it is not necessarily an electronic wristwatch. The present invention can be applied not only to electronic timepieces but also to electronic devices such as mobile phones and PDAs (personal digital assistants).
