Abstract

PROBLEM TO BE SOLVED: To provide a timepiece for efficiently inputting energy to a mechanical energy storing means by an automatic input mechanism. SOLUTION: Concerning a rotating spindle gear 52 transmitting rotation of a rotating spindle 51, a rotating speed of the rotating spindle 51 necessary for feeding one tooth of a storing means side transmission wheel 60 can be decreased by increasing a speed from the rotating spindle gear 52 to a first transmission wheel 53, and a spiral spring can be wound to small swing without need of largely swinging the rotating spindle like the conventional. Furthermore, energy input chance is increased by matching the position of the rotating spindle 51 with the phase of the storing means side transmission wheel 60, and input to an energy storing means is frequently performed to be further efficient.

Description

本発明は、自動入力機構付きの時計に関する。 The present invention relates to a timepiece with an automatic input mechanism.

従来、ぜんまい等の機械的エネルギー蓄積手段からの機械的エネルギーにより輪列を駆動するとともに、この輪列からの回転を受けて回転する発電機に電力を生じさせ、この電力により駆動される電子回路によって前記発電機の回転周期を制御することで、前記輪列を調速する時計の開発が進められている。
このような時計のムーブメントでは、ぜんまいを巻き上げて機械エネルギーを入力する機構として、巻真を操作して行う手動入力機構と回転錘の回転による自動入力機構とが併用されることがある。
各入力機構のうち、自動入力機構は、ムーブメントの中心を軸中心とする前記回転錘と、この回転錘の回転中心に対して偏心して設けられたら偏心軸部に係合されるレバー部材と、このレバー部材によって一方向に回転する蓄積手段側伝え車とを備えた構成であり、蓄積手段側伝え車と噛み合う角穴車を回転させてぜんまいを巻き上げる（特許文献１参照）。 Conventionally, the train wheel is driven by mechanical energy from mechanical energy storage means such as a mainspring, and an electric circuit driven by this power is generated by generating electric power in a rotating generator in response to rotation from the train wheel. Thus, the development of a timepiece that regulates the speed of the train wheel by controlling the rotation period of the generator is underway.
In such a timepiece movement, as a mechanism for winding the mainspring and inputting mechanical energy, a manual input mechanism operated by operating a winding stem and an automatic input mechanism based on rotation of a rotating weight may be used in combination.
Among the input mechanisms, the automatic input mechanism includes the rotating weight centered on the center of the movement, and a lever member that is engaged with the eccentric shaft portion when provided eccentric to the rotation center of the rotating weight, The lever member is configured to include a storage means-side transmission wheel that rotates in one direction, and the mainspring is wound up by rotating a square wheel that meshes with the storage means-side transmission wheel (see Patent Document 1).

特開２００１−１６６６６７号公報（図１）JP 2001-166667 A (FIG. 1)

しかしながら、特許文献１に記載された時計において、一般的に回転錘が一回転した時、偏心軸部に係合されるレバー部材が回転して、歯を４つまたは５つ送り、この蓄積手段側伝え車の送りにより角穴車を送って、ぜんまいを巻き上げるものである。このような構成では、蓄積手段側伝え車の一歯を送るためには、回転錘を７２度から９０度程度回転させる必要があり、例えば、回転錘の７２度以下の小さな動きに対しては、ぜんまいを巻き上げることができず、巻上げ効率が悪いという問題がある。 However, in the timepiece described in Patent Document 1, generally, when the rotary weight makes one rotation, the lever member engaged with the eccentric shaft portion rotates to feed four or five teeth, and this storage means The mainspring is wound up by sending a square hole wheel by sending a side transmission wheel. In such a configuration, in order to send one tooth of the transmission means side transmission wheel, it is necessary to rotate the rotating weight by about 72 to 90 degrees. For example, for a small movement of 72 degrees or less of the rotating weight. There is a problem that the mainspring cannot be wound and the winding efficiency is poor.

本発明の目的は、自動入力機構による機械的エネルギー蓄積手段へのエネルギー入力を効率的に行える時計を提供することである。 An object of the present invention is to provide a timepiece that can efficiently input energy to mechanical energy storage means by an automatic input mechanism.

本発明の時計は、機械的エネルギー蓄積手段からの機械的エネルギーにより輪列を駆動する時計であって、回転錘と、この回転錘の回転を回転レバー部材まで伝達する二つ以上の回転錘側伝え車と、これらの回転錘側伝え車の一つに設けられた偏心軸部に係合する前記レバー部材と、このレバー部材の係脱により一定方向に回転するとともに、この回転を前記機械的エネルギー蓄積手段へ伝達して、前記回転錘からのエネルギーを入力する蓄積手段側伝え車とで自動入力機構が構成され、この自動入力機構の前記二つ以上の回転錘側伝え車では、前記回転錘の回転が増速されることを特徴とする。 The timepiece of the present invention is a timepiece that drives a train wheel by mechanical energy from mechanical energy storage means, and includes a rotating weight and two or more rotating weight sides that transmit rotation of the rotating weight to a rotating lever member. A transmission wheel, the lever member engaged with an eccentric shaft portion provided in one of these rotary weight side transmission wheels, and rotation in a fixed direction by the engagement / disengagement of the lever member, An automatic input mechanism is constituted by an accumulation means side transmission wheel that transmits energy to the energy storage means and inputs energy from the rotary weight, and in the two or more rotation weight side transmission wheels of the automatic input mechanism, the rotation The rotation of the weight is increased.

このような本発明によれば、回転錘の回転が回転錘側伝え車間で増速されるので、蓄積手段側伝え車を一歯送るための回転錘の回転角が小さくてすむ。従って、従来のように回転錘を大きく振る必要がなく、小さな振りに対しても自動入力機構による機械的エネルギー蓄積手段へのエネルギー入力が確実に行われるようになり、入力効率が向上する。 According to the present invention, since the rotation of the rotating weight is increased between the rotating weight side transmission wheels, the rotation angle of the rotating weight for feeding one tooth of the accumulating means side transmission wheel can be reduced. Therefore, it is not necessary to shake the rotating weight greatly as in the prior art, and even with a small swing, the energy input to the mechanical energy storage means by the automatic input mechanism is reliably performed, and the input efficiency is improved.

本発明の時計では、前記増速比は、２以上の整数値が好ましい。
時計では一般的に、レバー部材の動作位置によって、蓄積手段側伝え車を回し易い位置と回し難い位置とがある。
そこで本発明では、複数の回転錘側伝え車での増速比を２以上の整数値とすることにより、回転錘とレバー部材との位相のずれをなくしている。これによれば、絶えずレバー部材による蓄積手段側伝え車の回し易い状態が確保され、エネルギーの入力効率がさらに向上する。 In the timepiece of the present invention, the speed increasing ratio is preferably an integer value of 2 or more.
Generally, in a timepiece, there are a position where the accumulation means side transmission wheel can be easily rotated and a position where it is difficult to rotate depending on the operating position of the lever member.
Therefore, in the present invention, the phase difference between the rotating weight and the lever member is eliminated by setting the speed increasing ratio in the plurality of rotating weight side transmission wheels to an integer value of 2 or more. According to this, a state in which the accumulation means side transmission wheel by the lever member is constantly rotated is ensured, and the energy input efficiency is further improved.

本発明の時計では、３時方向に前記回転錘が重なった位置と、前記レバー部材の前記蓄積手段側伝え車への係合位置との位相を合わせることが好ましい。
通常、腕にはめた時計においては、文字板の３時の位置が一番下の位置になることが多い。このため、本発明のように回転錘の位置が略３時の位置にある状態で、レバー部材によって蓄積手段側伝え車が回転するようにすれば、エネルギーの入力機会が増え、エネルギー蓄積手段への入力が頻繁に行われるようになって、一層効率的である。 In the timepiece of the invention, it is preferable that the phase of the position where the rotary weight overlaps in the 3 o'clock direction and the position where the lever member is engaged with the storage means transmission wheel are matched.
Usually, in a watch worn on an arm, the 3 o'clock position of the dial is often the lowest position. For this reason, if the storage member side transmission wheel is rotated by the lever member in the state where the rotary weight is at the position of about 3 o'clock as in the present invention, the energy input opportunity increases, and the energy storage means Is more efficient because it is frequently entered.

本発明によれば、自動入力機構による機械的エネルギー蓄積手段へのエネルギー入力を効率的に行えるという効果がある。 According to the present invention, there is an effect that energy can be efficiently input to the mechanical energy storage means by the automatic input mechanism.

以下、本発明の一実施形態を図面に基づいて説明する。
図１は、本実施形態に係る時計１に用いられるムーブメントの概略図を示す平面図、図２は、そのムーブメントの一部を示す断面図である。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１または図２において、時計１は、ぜんまい(機械エネルギー蓄積手段：図２)１０から発生する機械的エネルギーにより輪列２０を駆動し、この輪列２０からの回転を受けて回転する発電機３０で電力を発生させている。この発電機３０で得られる電力によって図示しない電子回路は発電機３０の回転周期を制御し、輪列２０を調速する電子制御式機械時計であ。この時計１は、ぜんまい１０を手動で巻き上げて機械的エネルギーを入力する手動入力機構４０と、自動で巻き上げて機械的エネルギーを入力する自動入力機構５０とを備えている 1 or 2, a timepiece 1 is a generator that drives a train wheel 20 by mechanical energy generated from a mainspring (mechanical energy storage means: FIG. 2) 10 and rotates by receiving the rotation from the train wheel 20. 30 generates power. An electronic circuit (not shown) is an electronically controlled mechanical timepiece that controls the rotation period of the generator 30 and adjusts the speed of the train wheel 20 by the electric power obtained by the generator 30. The timepiece 1 includes a manual input mechanism 40 that manually winds up the mainspring 10 and inputs mechanical energy, and an automatic input mechanism 50 that automatically winds up and inputs mechanical energy.

ぜんまい１０は、香箱歯車１１、香箱真１４、香箱蓋１２からなる香箱１３に収納され、内端が香箱真１４に固定され、外端があるトルク以上で香箱歯車１１をスリップするように取り付けられている。香箱真１４には角穴車１５が固定されていて、手動入力機構４０または自動入力機構５０によって角穴車１５が一方向に回転することによって、香箱真１４は角穴車１５と一体で回転するように構成されている。角穴車１５は、時計方向に回転し、反時計回りに回転しないように図示しないこはぜと噛み合っている。ぜんまい１０は内側から巻き上がり、反対にその外側から巻き戻ることで香箱歯車１１を回転させ、香箱歯車１１は、これに噛み合う輪列２０を回転させている。 The mainspring 10 is housed in a barrel 13 including a barrel gear 11, barrel 14 and barrel lid 12, the inner end is fixed to the barrel 14 and the outer end is attached to slip the barrel 11 at a torque higher than a certain torque. ing. A square wheel 15 is fixed to the barrel 14, and the square wheel 15 rotates in one direction by the manual input mechanism 40 or the automatic input mechanism 50, so that the barrel 14 rotates together with the square wheel 15. Is configured to do. The square wheel 15 rotates in a clockwise direction, and meshes with a helix (not shown) so as not to rotate counterclockwise. The mainspring 10 is rolled up from the inner side and, on the contrary, is wound back from the outer side to rotate the barrel gear 11, and the barrel gear 11 rotates the train wheel 20 engaged therewith.

輪列２０は、香箱歯車１１の回転を受ける二番車２と、以下順に増速するように噛み合った三番車３と、四番車４と、五番車５と、六番車６とを備えている。二番車２の筒かな２Ａには図示しない分針が取り付けられ、四番車４には図示しない秒針が取り付けられている。二番車２の筒かな２Ａの回転が日の裏車２１を介して筒車２２に伝達され、この筒車２２に図示しない時針が取り付けられている。 The train wheel 20 includes a second wheel 2 that receives rotation of the barrel gear 11, a third wheel 3, a fourth wheel 4, a fifth wheel 5, and a sixth wheel 6 that are meshed so as to increase in order. It has. A minute hand (not shown) is attached to the cylindrical pinion 2A of the second wheel & pinion 2, and a second hand (not shown) is attached to the fourth wheel & pinion 4. The rotation of the hour pinion 2A of the center wheel & pinion 2 is transmitted to the hour wheel 22 via the minute wheel 21, and an hour hand (not shown) is attached to the hour wheel 22.

発電機３０は、輪列２０の六番車６と噛み合う回転するロータ３１と、このロータ３１に取り付けられる永久磁石３１Ａの磁束を鎖交させる磁気回路形成のためのステータ３２と、このステータ３２を構成する一対のステータ材３２Ａに巻線され、かつ永久磁石３１が回転することで生じるステータ材３２Ａでの磁束変化を電力に変換する一対のコイル３３とを備えている。このコイル３３には、水晶振動子８１およびＩＣ８２を含む運針制御用の電子回路が形成された回路ブロック（回路形成部材）８０が電気的に接続されており、発電機３０によって発電された電力でこの電子回路を駆動し、ロータ３１に制動をかけて輪列２０を調速し、運針制御を行っている。なお、ロータ３１は、一体に回転する慣性板３１Ｂを備え、ステータ３２に形成されたロータ収容穴３２Ｂ内に配置されている。 The generator 30 includes a rotating rotor 31 that meshes with the sixth wheel 6 of the train wheel 20, a stator 32 for forming a magnetic circuit that links the magnetic flux of the permanent magnet 31A attached to the rotor 31, and the stator 32. A pair of coils 33 that are wound around a pair of stator materials 32A and that convert a magnetic flux change in the stator materials 32A generated by rotation of the permanent magnet 31 into electric power are provided. The coil 33 is electrically connected to a circuit block (circuit forming member) 80 in which an electronic circuit for hand movement control including a crystal resonator 81 and an IC 82 is formed, and the electric power generated by the generator 30 is used. The electronic circuit is driven, the rotor 31 is braked to adjust the speed of the train wheel 20, and the hand movement control is performed. The rotor 31 includes an inertia plate 31 B that rotates integrally, and is disposed in a rotor accommodation hole 32 B formed in the stator 32.

手動入力機構４０は、巻真４１を用いてぜんまい１０を巻上可能に構成されている。具体的に、巻真４１にはこれと一体に回転するつづみ車４２（図１では不図示）が貫挿されており、巻真４１が引き出されていない通常の状態では、巻真４１の回転がつづみ車４２に伝達され、つづみ車４２から巻真４１に同様に貫挿されたきち車４３に伝達される。きち車４３の回転は、丸穴車４４を介して伝え中間車４５に伝達され、伝え車６２を介して角穴車１５に伝達され、ぜんまい１０を巻き上げる。そして、巻真４１から伝え中間車４５までを含んで手動入力機構４０を形成している。なお、前述の手動入力機構４０を構成する部品の材質は、鋼鉄等の金属からなることが好ましい。 The manual input mechanism 40 is configured to wind up the mainspring 10 using a winding stem 41. Specifically, a pinion wheel 42 (not shown in FIG. 1) that rotates integrally with the winding stem 41 is inserted into the winding stem 41, and in a normal state in which the winding stem 41 is not pulled out, The rotation is transmitted to the pinion wheel 42 and is transmitted from the pinion wheel 42 to the chimney wheel 43 inserted in the winding stem 41 in the same manner. The rotation of the hour wheel 43 is transmitted through the round hole wheel 44 to the intermediate wheel 45 and is transmitted to the square wheel 15 through the transmission wheel 62 to wind up the mainspring 10. A manual input mechanism 40 is formed including the winding stem 41 to the intermediate wheel 45. In addition, it is preferable that the material of the components which comprise the above-mentioned manual input mechanism 40 consists of metals, such as steel.

ここで、丸穴車４４、伝え中間車４５、および伝え車６２は、伝え受け６１に軸支され、角穴車１５が取り付けられた香箱真１４の一端側（図２）は、輪列受け２５に軸支されている。また、丸穴車４４は、伝え受け６１の図中下側できち車４３と噛み合う丸穴本体車４４Ａと、伝え受け６１の図中上側で伝え中間車４５と噛み合う丸穴中間車４４Ｂとで構成され、巻真４１からの回転を伝え受け６１の下側から上側に出力している。これにより、その回転は、伝え受け６１の上側で回転する丸穴本体車４４Ａ、伝え中間車４５、伝え車６２、および角穴車１５を伝うことになる。すなわち、巻真４１の回転は、断面視した場合に、伝え受け６１に沿って略同一高さ位置に配置された車４４，４５，６２，１５によって伝達されることになる。 Here, the round hole wheel 44, the transmission intermediate wheel 45, and the transmission wheel 62 are pivotally supported by the transmission receiver 61, and one end side (FIG. 2) of the barrel complete 14 to which the square wheel 15 is attached is a train wheel receiver. 25 is pivotally supported. The round hole wheel 44 includes a round hole main body wheel 44A that meshes with the lower wheel 43 of the transmission receiver 61 in the drawing, and a round hole intermediate wheel 44B that meshes with the transmission intermediate wheel 45 on the upper side of the transmission tray 61 in the drawing. The rotation from the winding stem 41 is transmitted and output from the lower side to the upper side of the receiver 61. As a result, the rotation is transmitted through the round hole main body wheel 44 A, the transmission intermediate wheel 45, the transmission wheel 62, and the square hole wheel 15 that rotate on the upper side of the transmission receiver 61. That is, the rotation of the winding stem 41 is transmitted by the wheels 44, 45, 62, and 15 disposed at substantially the same height along the transmission receiver 61 when viewed in cross section.

さらに、各車１５，４４，４５，６２の上方では回転錘５１が回転可能に配置されている。この回転錘５１側からの平面視では、図１に示すように、伝え中間車４５は、巻真４１の左側に配置されて丸穴車４４と噛み合っており、また、伝え車６２およびぜんまい１０（角穴車１５）も巻真４１よりも左側に配置されている。これにより、巻真４１を一般の機械時計と同様、右側に回転させることでぜんまい１０を巻き上げることが可能である。なお、つづみ車４２およびきち車４３の互いの噛み合い歯によりラチェット機構が形成されており、巻真４１を左側に回転させると、つづみ車４２がかんぬき４６（図２）の付勢力に抗してきち車４３から外れるとともに、つづみ車４２が左側に空回りし、その回転がきち車４３に伝達されることはない。 Further, a rotating weight 51 is rotatably disposed above each of the cars 15, 44, 45, 62. In a plan view from the rotating weight 51 side, as shown in FIG. 1, the transmission intermediate wheel 45 is disposed on the left side of the winding stem 41 and meshes with the round hole wheel 44, and the transmission wheel 62 and the mainspring 10 are also in contact with each other. (Square wheel 15) is also arranged on the left side of winding stem 41. As a result, the mainspring 10 can be wound up by rotating the winding stem 41 to the right as in a general mechanical timepiece. A ratchet mechanism is formed by the meshing teeth of the pinion wheel 42 and the chimney wheel 43. When the winding stem 41 is rotated to the left, the pinion wheel 42 resists the urging force of the yoke 46 (FIG. 2). As a result, the clutch wheel 42 is idled to the left side and the rotation is not transmitted to the wheel 43.

一方、自動入力機構５０は、前記回転錘５１と、回転錘５１と一体に同心上で回転する導電性の回転錘歯車（回転錘側伝え車）５２と、この回転錘歯車５２に噛み合って増速回転する導電性の一番伝え車（回転錘側伝え車）５３と、この一番伝え車５３の回転に連動して偏心駆動され、これにより蓄積手段側伝え車６０側に進退運動する鉄系材料製のレバー部材５４とを備えている。
また、前記回転錘歯車５２と一番伝え車５３との歯数比が整数比となるように、回転錘歯車５２が一番伝え車５３より外径形状が大きく形成され、例えば、回転錘歯車５２の直径が２に対して、一番伝え車５３の直径が１に形成されている。すなわち、回転錘歯車５２から一番伝え車５３への増速比は「２」である。 On the other hand, the automatic input mechanism 50 is meshed with the rotating weight 51, a conductive rotating weight gear (rotating weight side transmission wheel) 52 that rotates concentrically with the rotating weight 51, and the rotating weight gear 52. Conductive first transmission wheel (rotating weight side transmission wheel) 53 that rotates at a high speed and iron that is eccentrically driven in conjunction with the rotation of the first transmission wheel 53 and thereby moves forward and backward toward the storage means side transmission wheel 60 side. And a lever member 54 made of a system material.
Further, the rotary weight gear 52 is formed to have a larger outer diameter than the first transmission wheel 53 so that the gear ratio between the rotary weight gear 52 and the first transmission wheel 53 is an integer ratio. The diameter of the transmission wheel 53 is 1 while the diameter of 52 is 2. That is, the speed increasing ratio from the rotary weight gear 52 to the first transmission wheel 53 is “2”.

レバー部材５４は、レバー部材本体５５と、このレバー部材本体５５から延長された弾性変形可能な引き爪５６および押し爪５７とを備え、一番伝え車５３に対して地板２３側に設けられている。図３において、レバー部材本体５５には案内穴が設けられ、この案内穴には一番伝え車５３の偏心軸部が嵌合されている。一番伝え車５３が回転すると、偏心した偏心軸部も回転し、これに係合したレバー部材本体５５が蓄積手段側伝え車６０に対して進退運動する。引き爪５６および押し爪５７は、レバー部材本体５５が往復動すると、それらの先端が蓄積手段側伝え車６０の径方向に対向した歯に交互に係脱する。 The lever member 54 includes a lever member main body 55, an elastically deformable pulling claw 56 and a push claw 57 extended from the lever member main body 55, and is provided on the base plate 23 side with respect to the first transmission wheel 53. Yes. In FIG. 3, the lever member main body 55 is provided with a guide hole, and the eccentric shaft portion of the transmission wheel 53 is fitted into the guide hole. When the transmission wheel 53 rotates most, the eccentric eccentric shaft portion also rotates, and the lever member main body 55 engaged therewith moves forward and backward with respect to the storage means side transmission wheel 60. When the lever member main body 55 reciprocates, the pulling claws 56 and the push claws 57 are alternately engaged with and disengaged from the teeth facing the radial direction of the storage means side transmission wheel 60.

また、レバー部材本体５５が蓄積手段側伝え車６０に対して後退する際には、引き爪５６が蓄積手段側伝え車６０に係合し、この状態で蓄積手段側伝え車６０の一歯を引く。このとき、押し爪５７は蓄積手段側伝え車６０との係合が外れている。レバー部材本体５５が蓄積手段側伝え車６０に対して前進する際には、押し爪５７が蓄積手段側伝え車６０に係合し、この状態で蓄積手段側伝え車６０の一歯を押す。以上の動作を交互に繰り返すことにより、蓄積手段側伝え車６０を一方向に間欠的に回転させ、角穴車１５を介してぜんまい１０を巻き上げる。 Further, when the lever member main body 55 moves backward with respect to the storage means side transmission wheel 60, the pulling claw 56 engages with the storage means side transmission wheel 60, and in this state, one tooth of the storage means side transmission wheel 60 is engaged. Pull. At this time, the push claw 57 is disengaged from the accumulation means side transmission wheel 60. When the lever member main body 55 moves forward with respect to the storage means side transmission wheel 60, the push claw 57 engages with the storage means side transmission wheel 60 and pushes one tooth of the storage means side transmission wheel 60 in this state. By repeating the above operation alternately, the accumulation means side transmission wheel 60 is intermittently rotated in one direction, and the mainspring 10 is wound up through the square hole wheel 15.

ここで、蓄積手段側伝え車６０の伝えかな６０Ａと角穴車１５の歯数比を、回転錘歯車５２と一番伝え車５３とで増速した分だけ減速させている。これにより自動入力機構５０全体としてみた減速比が、この増減速を行わない場合と同じになるため、ぜんまい１０がフル巻きになるまでに要する回転錘５１の回転数は変わらないが、回転錘５１の小さな動きに対しての巻上は向上する。 Here, the gear ratio of the transmission pinion 60A of the accumulating means side transmission wheel 60 and the square wheel 15 is reduced by the amount increased by the rotary weight gear 52 and the first transmission wheel 53. As a result, the speed reduction ratio as a whole of the automatic input mechanism 50 becomes the same as when the speed increase / decrease is not performed, and therefore the number of rotations of the rotating weight 51 required until the mainspring 10 is fully wound does not change, but the rotating weight 51 The roll-up for small movements is improved.

なお、手動入力機構４０の巻真４１の操作によって蓄積手段側伝え車６０が回転しているときには、ここでもラチェット機構の原理により、蓄積手段側伝え車６０から引き爪５６および押し爪５７が交互に弾性変形して外れ、巻真４１の操作で一番伝え車５３や回転錘５１（回転錘側伝え車５２）が回転することはない。
同様に、自動入力機構５０によって伝え車６２を回転させているときにおいては、手動入力機構４０の伝え中間車４５と伝え車６２との噛み合いを外す噛脱手段７０が作動し、巻真４１側が回転しないようになっている。 When the accumulating means side transmission wheel 60 is rotated by the operation of the winding stem 41 of the manual input mechanism 40, the pulling claw 56 and the pushing claw 57 are alternately arranged from the accumulating means side transmission wheel 60 here by the principle of the ratchet mechanism. The first transmission wheel 53 and the rotary weight 51 (the rotary weight side transmission wheel 52) are not rotated by the operation of the winding stem 41.
Similarly, when the transmission wheel 62 is rotated by the automatic input mechanism 50, the engagement / disengagement means 70 for releasing the engagement between the transmission intermediate wheel 45 of the manual input mechanism 40 and the transmission wheel 62 is operated, and the winding stem 41 side is It is designed not to rotate.

この噛脱手段７０は、詳細な説明を省略するが、概ね伝え中間車４５の中央に設けられた丸穴７１と、この丸穴７１に遊嵌状態で嵌合された断面凸レンズ状（一眼状）の伝え中間軸７２と、伝え中間車４５を軸方向に沿って伝え受け６１側に押圧保持する皿ばね状の保持部材７３とで構成されており、自動入力機構５０によって伝え車６２が回転すると、丸穴７１と伝え中間軸７２との間に形成された三日月状の隙間により、伝え中間車４５と伝え車６２との噛み合いが自動的に外れ、伝え車６２の回転は伝え中間車４５に伝達されないばかりか、これよりも巻真４１側の丸穴車４４およびきち車４３にも伝達されず、これらを回転させずにすむようになっている。 Although the detailed description is omitted, the biting means 70 is generally a round hole 71 provided at the center of the intermediate wheel 45, and a convex lens shape (single-lens shape) fitted into the round hole 71 in a loosely fitted state. ) Transmission intermediate shaft 72 and a disc spring-like holding member 73 that presses and holds the transmission intermediate wheel 45 toward the transmission receiver 61 along the axial direction. The transmission wheel 62 is rotated by the automatic input mechanism 50. Then, due to the crescent-shaped gap formed between the round hole 71 and the transmission intermediate shaft 72, the transmission intermediate wheel 45 and the transmission wheel 62 are automatically disengaged, and the rotation of the transmission wheel 62 is transmitted to the transmission intermediate wheel 45. Is not transmitted to the round hole wheel 44 and the chisel wheel 43 on the side of the winding stem 41 more than this, so that it is not necessary to rotate them.

次に、図１に基づいて、レバー部材５４の蓄積手段側伝え車６０との係合位置の位相について説明する。
レバー部材本体５５の先端部は、一番伝え車５３の偏心軸部の位置によって、引き爪５６および押し爪５７が蓄積手段側伝え車６０に対して交互に係脱し、当該蓄積手段側伝え車６０を回転させるが、この引き爪５６が蓄積手段側伝え車６０から外れ、押し爪５７が蓄積手段側伝え車６０に係合する間と、押し爪５７が蓄積手段側伝え車６０から外れ、引き爪５６が蓄積手段側伝え車６０に係合する間とが、蓄積手段側伝え車６０が回転しない位置、つまりぜんまいを巻かない位置であり、押し爪５７および引き爪５６が蓄積手段側伝え車６０と係合し、押す時または引く時に回転する位置、つまりぜんまいが巻かれる位置である。そして、本実施形態では、通常腕にはめた時計１の位置は、文字板の３時方向が下に向くことが多いため、本実施形態では、回転錘５１の位置が略３時方向の位置にある状態で、蓄積手段側伝え車６０が回転する位置の位相に合わせられている。 Next, the phase of the engagement position of the lever member 54 with the storage means side transmission wheel 60 will be described with reference to FIG.
The leading end of the lever member main body 55 is alternately engaged with and disengaged from the accumulation means side transmission wheel 60 by the pulling claw 56 and the push claw 57 depending on the position of the eccentric shaft portion of the transmission wheel 53. 60, the pulling claw 56 is disengaged from the accumulating means side transmission wheel 60, while the pushing claw 57 is engaged with the accumulating means side transmission wheel 60, and the pushing claw 57 is disengaged from the accumulating means side transmission wheel 60. The time during which the pulling claw 56 engages with the storage means side transmission wheel 60 is a position where the storage means side transmission wheel 60 does not rotate, that is, a position where the mainspring is not wound. A position where the mainspring is rotated when the wheel 60 is engaged and pushed or pulled, that is, a position where the mainspring is wound. In the present embodiment, the position of the timepiece 1 that is usually worn on the arm is often directed downward in the 3 o'clock direction of the dial. Therefore, in this embodiment, the position of the rotary weight 51 is a position in the approximately 3 o'clock direction. In this state, the phase is adjusted to the position at which the storage means side transmission wheel 60 rotates.

このような本実施形態によれば、以下のような効果がある。
（１）回転錘５１を含む自動入力機構５０では、回転錘歯車５２と一番伝え車５３との間で増速されているので、蓄積手段側伝え車６０を一歯送るための回転錘５１の回転角を小さくできる。従って、従来のように回転錘５１を大きく振る必要がなく、小さな振りに対しても自動入力機構５０によるぜんまい１０へのエネルギー入力を確実に行え、入力効率を向上させることができる。 According to this embodiment, there are the following effects.
(1) In the automatic input mechanism 50 including the rotary weight 51, the speed is increased between the rotary weight gear 52 and the first transmission wheel 53, so the rotary weight 51 for feeding the accumulation means side transmission wheel 60 by one tooth. The rotation angle can be reduced. Therefore, it is not necessary to shake the rotating weight 51 as in the conventional case, and even with a small swing, the energy can be reliably input to the mainspring 10 by the automatic input mechanism 50, and the input efficiency can be improved.

（２）回転錘歯車５２から一番伝え車５３への増速比は整数値であるから、回転錘５１とレバー部材５４との位相のずれをなくすことができる。これによれば、絶えずレバー部材５４による蓄積手段側伝え車６０の回し易い状態を確保でき、エネルギーの入力効率をさらに向上させることができる。 (2) Since the speed increasing ratio from the rotary weight gear 52 to the first transmission wheel 53 is an integer value, the phase shift between the rotary weight 51 and the lever member 54 can be eliminated. According to this, it is possible to ensure a state in which the accumulation means side transmission wheel 60 is constantly rotated by the lever member 54, and it is possible to further improve the energy input efficiency.

（３）通常腕にはめた時計１においては、文字板の３時の位置が一番下の位置になることが多いが、本実施形態では、回転錘５１の位置が略３時の位置にある状態で、レバー部材５４によって蓄積手段側伝え車６０が回転するように位相が設定されているから、腕の動きに連動させてエネルギーの入力機会を増やすことができ、ぜんまい１０への入力を頻繁におこなうことができて、一層効率的である。 (3) In the timepiece 1 usually worn on the wrist, the 3 o'clock position of the dial plate is often the lowest position, but in this embodiment, the position of the rotary weight 51 is approximately the 3 o'clock position. Since the phase is set so that the accumulation means side transmission wheel 60 is rotated by the lever member 54 in a certain state, the input opportunity of energy can be increased in conjunction with the movement of the arm, and the input to the mainspring 10 can be performed. It can be done frequently and is more efficient.

（４）さらに、回転錘歯車５２と一番伝え車５３との間で増速し、その分を伝えかな６０Ａと角穴車１５との間で減速させることにより、巻上時のレバー部材５４におけるトルクが小さくなるため、レバー部材５４のばね力を小さくでき、レバー部材５４の応力を軽減できる。従って、巻上性を向上させることができるとともに、爪端部の磨耗も減少させることができ、磨耗によって発生した切粉による電子回路の導通不良および輪列２０の回転不良を防止できる。 (4) Further, the lever member 54 at the time of winding is increased by increasing the speed between the rotary spindle gear 52 and the first transmission wheel 53 and decelerating that amount between the transmission pinion 60A and the square hole wheel 15. Therefore, the spring force of the lever member 54 can be reduced, and the stress of the lever member 54 can be reduced. Therefore, the rollability can be improved, the wear of the claw ends can be reduced, and the poor conduction of the electronic circuit and the poor rotation of the train wheel 20 due to the chips generated by the wear can be prevented.

（５）回転錘歯車５２から一番伝え車５３への増速に伴って、回転錘歯車５２の外径形状が大きくなっているので、巻真４１を回路ブロック８０上の電子回路よりも、回転錘歯車５２の外周へ近づけることができる。このことより、静電気が外部操作部材である巻真４１から電子回路まで到達するまでに、静電気は最短の導通経路を通るので、電子回路に至る導通経路を通ることなく、回転錘歯車５２へ逃げ、電子回路の誤動作を防止できる。 (5) Since the outer diameter shape of the rotary weight gear 52 is increased with the speed increase from the rotary weight gear 52 to the first transmission wheel 53, the winding stem 41 is more than the electronic circuit on the circuit block 80. It is possible to approach the outer periphery of the rotary weight gear 52. Thus, since the static electricity passes through the shortest conduction path before the static electricity reaches the electronic circuit from the winding stem 41 as the external operation member, it escapes to the rotary weight gear 52 without passing through the conduction path leading to the electronic circuit. It is possible to prevent malfunction of the electronic circuit.
