Description

本発明はカレンダ付時計に係る。   The present invention relates to a timepiece with calendar.

日付が表示可能なカレンダ付の腕時計自体は周知である。ぜんまいで駆動される機械式腕時計の場合、巻真が通常位置（０段目）にあるときは、巻真の一方向回転によりぜんまいが巻上げられ、巻真が一段目ないし一段引出位置にあるときは、巻真の一方向回転により日車が回転されてカレンダ修正が行われ、巻真が二段目ないし二段引出位置にあるときは、巻真の回転により時刻表示針が回転されて時刻修正が行われる。   A calendar-equipped wristwatch that can display the date is well known. In the case of a mechanical wristwatch driven by a mainspring, when the winding stem is in the normal position (0th stage), the mainspring is wound up by rotating the winding stem in one direction, and the winding stem is in the 1st or 1st drawing position. The date indicator is rotated by rotating the winding stem in one direction to correct the calendar. When the winding stem is at the second or second pull-out position, the time indicator is rotated by rotating the winding stem. Corrections are made.

この種のカレンダ付で機械式の腕時計は、典型的には、回転中心軸線のまわりで回転可能であり、且つ基準位置、該基準位置から一段階引出された一段引出位置（カレンダ修正位置）及び前記基準位置から二段階引出された二段引出位置（時刻修正位置）との間で前記回転中心軸線の延在方向に出入れ可能な巻真と、該巻真と一体的に回転可能に且つ巻真の回転中心軸線の延在方向に巻真に対して相対移動可能に巻真に嵌合されたつづみ車であって、巻真が基準位置にあるときには一端大径部の端面にある乙歯できち車に噛合されてぜんまいの巻上げを可能にし、巻真が一段引出位置にあるときには他端大径部の端面にある甲歯がカレンダ修正位置にある小鉄車等を介してカレンダ修正機構に噛合されてカレンダ修正を可能にし、巻真が二段引出位置にあるときには時刻修正位置にある小鉄車等を介して針位置修正機構に噛合されて時刻修正を可能にするものとを有する（例えば、特許文献１）。   Such a calendar-equipped mechanical wristwatch is typically rotatable around a rotation center axis, and a reference position, a one-stage extraction position (calendar correction position) extracted from the reference position by one step, and A winding stem that can be taken in and out in the extending direction of the rotation center axis line between a two-stage drawing position (time correction position) drawn in two stages from the reference position, and capable of rotating integrally with the winding stem; A pinion wheel fitted to the winding stem so as to be movable relative to the winding stem in the extending direction of the rotation center axis of the winding stem, and when the winding stem is at the reference position, it is at one end face of the large-diameter portion. The mainspring can be wound up by being engaged with the toothed wheel and the mainspring can be wound. Engage with the mechanism to enable calendar correction, with two steps When in the out position and a an enabling been meshed time correction to the hand position correction mechanism through the setting wheel or the like at the time instant correction position (e.g., Patent Document 1).

しかしながら、この種のカレンダ付機械式腕時計では、小鉄車等の位置を切り換えて所望のカレンダ修正と所望の時刻修正とを選択的に行わせる必要があることから、構造が複雑になるだけでなく、構造の複雑化に関連して部品点数が増大しコスト高になり易い。
特開平１１−１８３６４９号公報（例えば、図４及び図６並びに図９及び図２１と、これらに関連する明細書の説明部分） However, in this type of mechanical wristwatch with a calendar, it is necessary not only to change the position of a small iron wheel or the like to selectively perform a desired calendar correction and a desired time correction. The number of parts increases in connection with the complicated structure, and the cost tends to increase.
Japanese Patent Laid-Open No. 11-183649 (for example, FIG. 4 and FIG. 6 and FIG. 9 and FIG. 21 and the description part of the description related to these)

本発明は前記した点に鑑みなされたものであって、その目的とするところは、構造が簡単化され得るカレンダ付時計を提供することにある。   The present invention has been made in view of the above-described points, and an object of the present invention is to provide a calendar watch with a simplified structure.

本発明のカレンダ付時計は、前記目的を達成すべく、回転中心軸線のまわりで回転可能な巻真であって、基準位置、該基準位置から一段階引出された一段引出位置及び前記基準位置から二段階引出された二段引出位置の間で前記回転中心軸線の延在方向に出入れ可能なものと、該巻真と一体的に回転可能に且つ巻真の回転中心軸線の延在方向に巻真に対して相対移動可能に巻真に嵌合され、カレンダ修正機構駆動用歯車部を一端の大径部に備えると共に日の裏車駆動用歯車部を他端に備えたつづみ車であって、巻真が一段引出位置に設定される際に一段目位置に設定されてカレンダ修正機構駆動用歯車部がカレンダ修正機構の入力側歯車に噛合され、巻真が二段引出位置に設定される際に二段目位置に設定されて日の裏車駆動用歯車部で日の裏車に噛合されるものと、カレンダ修正機構の前記入力側歯車を回転自在に支持すると共に該入力側歯車とカレンダ修正機構の下流側歯車部とを噛合させる噛合位置と該噛合を解除する噛合解除位置との間で可動であり且つ係合部を備えた支持案内部材であって、巻真の一段引出位置から二段引出位置への引出しに伴うつづみ車の一段目位置から二段目位置への移動の際に前記係合部でつづみ車の前記一端大径部に係合されて噛合位置から噛合解除位置に移動されるものとを有する。   The calendar watch of the present invention is a winding stem that can be rotated around a rotation center axis to achieve the above-mentioned object, and includes a reference position, a one-stage extraction position that is extracted one step from the reference position, and the reference position. Between the two-stage extraction position where the two-stage extraction has been performed, and the rotation center axis extending in the direction in which the rotation center axis extends; A handwheel that is fitted to the winding stem so as to be movable relative to the winding stem, and has a calendar correction mechanism driving gear portion at one end of the large diameter portion and a reverse wheel driving gear portion at the other end. When the winding stem is set to the first-stage drawing position, it is set to the first-stage position, the calendar correction mechanism drive gear is engaged with the input side gear of the calendar correction mechanism, and the winding stem is set to the second-stage extraction position. Is set to the second stage position when the A meshing position for releasing the meshing and a meshing position for meshing the input side gear and the downstream gear part of the calendar correcting mechanism while rotatably supporting the input side gear of the calendar correction mechanism A support guide member that is movable between positions and provided with an engaging portion, and is a first-stage position from the first-stage position of the handwheel accompanying the pulling from the first-stage drawing position of the winding stem to the second-stage drawing position. And the engagement portion is engaged with the one end large diameter portion of the wheel and moved to the mesh release position from the mesh position.

本発明のカレンダ付時計では、「該巻真と一体的に回転可能に且つ巻真の回転中心軸線の延在方向に巻真に対して相対移動可能に巻真に嵌合され、カレンダ修正機構駆動用歯車部を一端の大径部に備えると共に日の裏車駆動用歯車部を他端に備えたつづみ車であって、巻真が一段引出位置に設定される際に一段目位置に設定されてカレンダ修正機構駆動用歯車部がカレンダ修正機構の入力側歯車に噛合され、巻真が二段引出位置に設定される際に二段目位置に設定されて日の裏車駆動用歯車部で日の裏車に噛合されるもの」が設けられているので、つづみ車によってカンレダ修正機構及び日の裏車を直接選択的に回転させ得るから、カレンダ修正及び時刻修正に関連する構造を簡単化することが可能になる。   In the timepiece with calendar according to the present invention, “a calendar correcting mechanism is fitted to the winding stem so that it can rotate integrally with the winding stem and can move relative to the winding stem in the extending direction of the rotation center axis of the winding stem. A spur wheel provided with a driving gear part at the large diameter part at one end and a reverse wheel driving gear part at the other end, and when the winding stem is set at the one-stage pull-out position, When set, the calendar correction mechanism drive gear is meshed with the input side gear of the calendar correction mechanism, and when the winding stem is set to the two-stage pull-out position, it is set to the second stage position and the reverse wheel drive gear. Since there is a part that meshes with the minute wheel ”, the candela correction mechanism and the minute wheel can be directly and selectively rotated by the pinwheel, so the structure related to calendar correction and time correction. Can be simplified.

また、本発明のカレンダ付時計では、「カレンダ修正機構の前記入力側歯車を回転自在に支持すると共に該入力側歯車とカレンダ修正機構の下流側歯車部とを噛合させる噛合位置と該噛合を解除する噛合解除位置との間で可動であり且つ係合部を備えた支持案内部材であって、巻真の一段引出位置から二段引出位置への引出しに伴うつづみ車の一段目位置から二段目位置への移動の際に前記係合部でつづみ車の前記一端大径部に係合されて噛合位置から噛合解除位置に移動されるもの」が設けられているので、つづみ車によって日の裏車を直接的に回転させる時刻修正の際には、カレンダ修正機構の下流側歯車とカレンダ修正機構の入力側歯車との噛合が解除されて、時刻修正がカレンダ修正機構により干渉を受けるのを確実に避け得る。   In the calendar-equipped timepiece of the present invention, “the meshing position where the input side gear of the calendar correcting mechanism is rotatably supported and the input side gear meshes with the downstream gear portion of the calendar correcting mechanism and the meshing is released. The support guide member is movable between the mesh release position and is provided with an engaging portion. The support guide member is provided with a second position from the first-stage position of the handwheel when the winding stem is pulled from the first-stage extraction position to the second-stage extraction position. Since the engagement wheel is provided with the engagement portion engaged with the one end large-diameter portion of the wheel during movement to the step position, the wheel is moved. When the time is adjusted to rotate the minute wheel directly, the meshing between the downstream gear of the calendar correction mechanism and the input side gear of the calendar correction mechanism is released, and the time correction interferes with the calendar correction mechanism. I can definitely avoid it.

すなわち、本発明のカレンダ付時計では、巻真が一段引出位置に設定される場合には、つづみ車も一段目位置に設定され、つづみ車の一端大径部にあるカレンダ修正機構駆動用歯車部がカレンダ修正機構の入力側歯車に噛合され、巻真の一方向回転に応じてカレンダ修正機構の入力側歯車がつづみ車を介して回転されてカレンダ修正が行われる。巻真の一段引出位置では、つづみ車の他端にある日の裏車駆動用歯車部と日の裏車とは噛合されておらず、つづみ車の回転は時刻修正機構には影響を及ぼさない。一方、本発明のカレンダ付時計において、巻真が二段引出位置に設定される場合には、つづみ車も二段目位置に設定される。巻真の一段引出位置から二段引出位置への引出しに伴うつづみ車の一段目位置から二段目位置への移動の際に、係合案内部が係合部でつづみ車の一端大径部に係合されて噛合位置から噛合解除位置に移動されるので、つづみ車が二段目位置に設定されると、つづみ車や巻真の回転はカレンダ修正機構には影響を及ぼさない。また、つづみ車が二段目位置に設定されると、つづみ車の日の裏車駆動用歯車部が日の裏車に直接噛合されるので、巻真及びつづみ車の回転に応じて時刻表示針の位置が修正されて時刻修正が行われ得る。   That is, in the calendar watch of the present invention, when the winding stem is set to the first-stage pull-out position, the pinion wheel is also set to the first-stage position, and is used for driving the calendar correction mechanism at the large-diameter portion at one end of the pinch wheel. The gear portion is meshed with the input side gear of the calendar correcting mechanism, and the input side gear of the calendar correcting mechanism is rotated via the pinion wheel according to the one-way rotation of the winding stem, thereby correcting the calendar. At the first position of the winding stem, the minute wheel driving gear and the minute wheel at the other end of the hour wheel are not engaged with each other, and the rotation of the hour wheel has an effect on the time adjustment mechanism. Does not reach. On the other hand, in the timepiece with calendar of the present invention, when the winding stem is set at the second-stage drawing position, the pinion wheel is also set at the second-stage position. When the handwheel is moved from the first-stage position to the second-stage position when the winding stem is pulled from the first-stage pull-out position to the second-stage pull-out position, the engagement guide section is connected to the second-stage position. Since it is engaged with the diameter and moved from the meshing position to the meshing release position, if the handwheel is set to the second stage position, the rotation of the handwheel or winding stem will not affect the calendar correction mechanism. Absent. Also, when the handwheel is set to the second stage position, the minute wheel driving gear part of the minute wheel is directly meshed with the minute wheel, so that it corresponds to the winding stem and the rotation of the toothed wheel. Thus, the position of the time display hand is corrected and the time can be corrected.

以上のような本発明のカレンダ付時計では、カレンダ修正機構の入力側歯車の支持案内部材自体が、つづみ車とカレンダ修正機構との噛合及びその解除に直接係るので、当該支持案内部材以外に可動部材が実際上不要であるから、構造が簡単化され得、関連部品点数が低減され得、コストが最低限に抑えられ得る。   In the calendar-equipped timepiece according to the present invention as described above, the support guide member of the input side gear of the calendar correction mechanism directly relates to the engagement and release of the handwheel and the calendar correction mechanism. Since the movable member is practically unnecessary, the structure can be simplified, the number of related parts can be reduced, and the cost can be minimized.

なお、巻真に関して、上記の基準位置、一段引出位置及び二段引出位置がある限り、三つの位置以外に第四や第五の位置が更にあってもよく、第四や第五の位置が三つの位置の中間にあってもよい。   Regarding the winding stem, as long as there are the above-mentioned reference position, one-stage drawing position and two-stage drawing position, there may be further fourth and fifth positions in addition to the three positions, and the fourth and fifth positions It may be in the middle of the three positions.

また、本発明のカレンダ付時計において、つづみ車のカレンダ修正機構駆動用歯車部は、一端に一つだけある大径部に形成されるけれども、所望ならば、つづみ車が、その一端に軸方向に間隔をおいて複数の大径部を備えていてもよく、その場合、一端（の）大径部の末端に位置する大径部であっても該末端よりも内側に位置する大径部であってもよい。また、つづみ車のカレンダ修正機構駆動用歯車部は、典型的には、大径部の周面に形成されるけれども、場合によっては、大径部の内向きの端面の外周部に形成されてもよい。後者の場合、カレンダ修正機構の入力側歯車自体が支持案内部材の係合部としても働き得る。   In addition, in the calendar timepiece of the present invention, the calendar correction mechanism drive gear portion of the pulley wheel is formed in a large-diameter portion having only one end, but if desired, the pulley wheel is at one end. A plurality of large-diameter portions may be provided at intervals in the axial direction. In that case, even the large-diameter portion located at the end of the large-diameter portion at one end is A diameter part may be sufficient. Further, the calendar correction mechanism drive gear portion of the spell wheel is typically formed on the peripheral surface of the large diameter portion, but in some cases, it is formed on the outer peripheral portion of the inward end surface of the large diameter portion. May be. In the latter case, the input side gear itself of the calendar correcting mechanism can also function as the engaging portion of the support guide member.

本発明のカレンダ付時計において、支持案内部材の係合部は、つづみ車の前記一端大径部に係合され得る限りどのような位置にあってもどのような構造や形状を備えていてもよいけれども、典型的には、巻真が一段引出位置にある際につづみ車の前記一端大径部と該つづみ車の軸線方向の他端との間の環状凹部に遊嵌される係合突起部からなる。この場合、おしどりによって揺動されるかんぬきの一端が係合される環状凹部を形成すべく両端に大径部を有するつづみ車の形状が、そのまま、係合突起部との係合に有効に活用され得る。   In the calendar watch of the present invention, the engaging portion of the support guide member has any structure or shape as long as it can be engaged with the one end large diameter portion of the handwheel. However, typically, when the winding stem is in the one-stage drawing position, it is loosely fitted into an annular recess between the large diameter portion of the one end of the pinion wheel and the other end in the axial direction of the pinion wheel. It consists of an engaging protrusion. In this case, the shape of the pinion wheel having the large diameter portions at both ends so as to form an annular recess to which one end of the yoke swung by the setting lever is engaged is effectively used for the engagement with the engaging protrusion as it is. Can be utilized.

本発明のカレンダ付時計では、典型的には、支持案内部材を噛合解除位置から噛合位置に偏倚させる弾性偏倚手段を有する。これにより、巻真が二段引出位置から基準位置に戻される際に支持案内部材も元の位置に戻され得る。   The calendar watch of the present invention typically has elastic biasing means for biasing the support guide member from the mesh release position to the mesh position. Thereby, when the winding stem is returned from the two-stage drawing position to the reference position, the support guide member can also be returned to the original position.

本発明のカレンダ付時計において、上記の弾性偏倚手段は、いかなる静置部材に取付けられていてもよいけれども、好ましくは、弾性偏倚手段が日車押えに一体的に形成されたバネ部からなる。この場合、部品点数を最小限に抑えたままで、所望の機能を実現し得る。   In the timepiece with calendar according to the present invention, the elastic biasing means may be attached to any stationary member, but preferably, the elastic biasing means is formed of a spring portion integrally formed with the date indicator presser. In this case, a desired function can be realized while minimizing the number of parts.

本発明のカレンダ付時計において、係合突起部は、どのようなものであってもよいけれども、好ましくは、支持案内部材が軸部を備え、係合突起部が軸部の一端に一体的に形成され該軸部の端面の一部から該軸部の延在方向に突出した突起からなる。突起の横断面は、例えば、円弧と該円弧の弦とにより規定される形状を有する。この場合、突起を支持案内部材の本体部をなす軸部と一体的に形成し得、部品点数も最低限に抑えられ得る。   In the timepiece with calendar according to the present invention, the engagement protrusion may be any type, but preferably, the support guide member includes a shaft portion, and the engagement protrusion is integrally formed with one end of the shaft portion. The projection is formed and protruded from a part of the end surface of the shaft portion in the extending direction of the shaft portion. The cross section of the protrusion has, for example, a shape defined by an arc and a chord of the arc. In this case, the protrusion can be formed integrally with the shaft portion that forms the main body portion of the support guide member, and the number of parts can be minimized.

本発明のカレンダ付時計は、電池などで駆動されるタイプのものであってもよいけれども、典型的には、巻真が基準位置にある際にゼンマイの巻上げが可能な機械式時計からなる。   The calendar timepiece of the present invention may be of a type driven by a battery or the like, but typically comprises a mechanical timepiece capable of winding the mainspring when the winding stem is at the reference position.

なお、時計は、いかなるサイズのものであってもよいけれども、典型的には、腕時計のような小型のものからなる。   The watch may be of any size, but is typically a small watch such as a wristwatch.

本発明の好ましい一実施の形態を添付図面に示した好ましい一実施例に基づいて説明する。   A preferred embodiment of the present invention will be described based on a preferred embodiment shown in the accompanying drawings.

図１から図９には、本発明による好ましい一実施例の機械式でカレンダ付の腕時計１が示されている。   FIG. 1 to FIG. 9 show a mechanical and calendar wristwatch 1 according to a preferred embodiment of the present invention.

カレンダ付機械式腕時計１は巻真２０を備え、巻真２０は、その中心軸線ＢのまわりでＢ１，Ｂ２方向に回転可能に且つ長手方向Ａに沿ってＡ１，Ａ２方向に二段階で引出し・押込み可能にケースないし胴（図示しない）をＡ方向に貫通して配置されている。以下では、図２，図５及び図８に示したように巻真２０が一段階引出された位置ないし状態Ｓｍ１を巻真２０の一段引出位置といい、巻真が位置Ｓｍ１にあるときの時計１の状態を巻真一段目Ｓ１という。また、図３，図６及び図９に示したように巻真２０が二段階引出された位置ないし状態Ｓｍ２を巻真２０の二段引出位置といい、巻真２０が位置Ｓｍ２にあるときの時計１の状態を巻真二段目Ｓ２という。なお、図１，図４及び図７に示したように巻真２０がＡ２方向に押込まれた通常位置ないし状態Ｓｍ０を巻真２０の基準位置といい、巻真２０が位置Ｓｍ０にあるときの時計１の状態を巻真０段目Ｓ０という。   The mechanical wristwatch 1 with a calendar includes a winding stem 20, which can be rotated in the B1 and B2 directions around its central axis B and pulled out in two stages along the longitudinal direction A in the A1 and A2 directions. A case or a trunk (not shown) is inserted in the A direction so as to be able to be pushed. Hereinafter, the position or state Sm1 where the winding stem 20 is pulled out by one step as shown in FIGS. 2, 5, and 8 will be referred to as the one-step drawing position of the winding stem 20, and the timepiece when the winding stem is at the position Sm1 will be described. The state 1 is referred to as a winding stem first stage S1. Further, as shown in FIGS. 3, 6 and 9, the position or state Sm2 where the winding stem 20 is pulled out in two stages is called the two-stage drawing position of the winding stem 20, and the winding stem 20 is located at the position Sm2. The state of the timepiece 1 is referred to as a winding stem second stage S2. 1, 4 and 7, the normal position or state Sm0 where the winding stem 20 is pushed in the A2 direction is referred to as a reference position of the winding stem 20, and the winding stem 20 is located at the position Sm0. The state of the timepiece 1 is referred to as a winding stem 0th stage S0.

図７〜図９からわかるように、巻真２０は、大径円柱状部２１，２２、小径円柱状部２３、中径柱状部２４及びスプライン付柱状部２５を備える。大径円柱状部２１，２２の間の小径円柱状部２３には、おしどり３１の一端３１ａが係合され、中径柱状部２４にはきち車３２が嵌着されている。柱状部２５には、巻真２０の柱状部２５の延在方向Ａに該柱状部２５に対して移動可能に且つ巻真２０のＢ１，Ｂ２方向の回転に際しては巻真２０と一体的にＢ１，Ｂ２方向に回転されるように、つづみ車４０が嵌合されている。つづみ車４０は、両端に大径部４１，４２を備える。一端の大径部４１は、端面に乙歯４３を、周面にカレンダ修正機構駆動用歯車部としての別の歯車部４４を有し、他端の大径部４２は端面に甲歯４５を有する。つづみ車４０の両端大径部４１，４２間の小径部４６には、おしどり３１の揺動に応じて揺動されるかんぬき３３の一端３３ａが係合されている。   As can be seen from FIGS. 7 to 9, the winding stem 20 includes large diameter cylindrical portions 21 and 22, a small diameter cylindrical portion 23, a medium diameter columnar portion 24, and a splined columnar portion 25. One end 31 a of a setting lever 31 is engaged with the small diameter cylindrical portion 23 between the large diameter cylindrical portions 21 and 22, and a chisel wheel 32 is fitted to the medium diameter columnar portion 24. The columnar portion 25 is integrally movable with the winding stem 20 so as to be movable with respect to the columnar portion 25 in the extending direction A of the columnar portion 25 of the winding stem 20 and when the winding stem 20 rotates in the B1 and B2 directions. , B2 is rotated so as to be rotated in the B2 direction. The clutch wheel 40 includes large diameter portions 41 and 42 at both ends. The large-diameter portion 41 at one end has a toothed tooth 43 on the end surface, another gear portion 44 as a calendar correction mechanism driving gear portion on the peripheral surface, and the large-diameter portion 42 on the other end has an instep 45 on the end surface. Have. One end 33 a of a yoke 33 that is swung according to the swing of the setting lever 31 is engaged with the small diameter portion 46 between the large diameter portions 41 and 42 at both ends of the handwheel 40.

従って、巻真２０がＡ１方向に引出されると、一端３１ａの概ねＡ１方向の変位に伴っておしどり３１が一方向に回動ないし揺動されると共に該おしどり３１に係合されたかんぬき３３が反対方向に回動ないし揺動されることにより、かんぬき３３の一端３３ａが概ねＡ２方向に変位され、つづみ車４０を巻真２０に対してＡ２方向に変位させる。巻真２０が基準位置Ｓｍ０にある状態Ｓ０ではつづみ車４０が基準位置Ｓｔ０を採り（図７）、巻真２０が一段引出位置Ｓｍ１にある状態Ｓ１ではつづみ車４０が一段目の位置Ｓｔ１を採り（図８）、巻真２０が二段引出位置Ｓｍ２にある状態Ｓ２ではつづみ車４０が一段目の位置Ｓｔ２を採る（図９）。   Therefore, when the winding stem 20 is pulled out in the A1 direction, the setting lever 31 is rotated or swung in one direction in accordance with the displacement of the one end 31a in the A1 direction, and the yoke 33 engaged with the setting lever 31 is moved. By rotating or swinging in the opposite direction, one end 33a of the yoke 33 is generally displaced in the A2 direction, and the clutch wheel 40 is displaced in the A2 direction with respect to the winding stem 20. In the state S0 in which the winding stem 20 is at the reference position Sm0, the pinion wheel 40 takes the reference position St0 (FIG. 7), and in the state S1 in which the winding stem 20 is at the first pull-out position Sm1, the pinion wheel 40 is at the first stage position St1. (FIG. 8), and in the state S2 in which the winding stem 20 is in the second-stage extraction position Sm2, the pinion wheel 40 takes the first-stage position St2 (FIG. 9).

ケースないし胴２内において、地板４には、きち車３２の歯車部３２ａに噛合した丸穴車１１が装着され、丸穴車１１には揺動丸穴車１２の歯車部１３が噛合し、揺動丸穴車１２の歯車部１４は二番伝え車１５の歯車部１５ａに噛合し、二番伝え車１５には歯車部１６を介して香箱車（図示せず）に結合された角穴車１７が噛合している。   In the case or the torso 2, the round hole wheel 11 meshed with the gear portion 32 a of the chi-wheel 32 is attached to the base plate 4, and the gear portion 13 of the swinging round hole wheel 12 is meshed with the round hole wheel 11, The gear portion 14 of the oscillating round hole wheel 12 meshes with the gear portion 15a of the second transmission wheel 15, and the second transmission wheel 15 is connected to a barrel wheel (not shown) via a gear portion 16. Car 17 is engaged.

従って、きち車３２が回転されると、該きち車３２の回転は、丸穴車１１，揺動丸穴車１２及び二番伝え車１５を介して角穴車１７に伝達されて、香箱車のぜんまいが巻かれる。   Accordingly, when the chimney wheel 32 is rotated, the rotation of the chimney wheel 32 is transmitted to the square hole wheel 17 via the round hole wheel 11, the swinging round hole wheel 12, and the second transmission wheel 15, and the barrel wheel. The mainspring is wound.

図１〜図３に加えて図４〜図６等からわかるように、胴２の内周にほぼ沿うように配置された日車５０は、内周に係合歯５１を備える。日車５０の文字板側には、図１及び図３や図７〜図９からわかるように、日車押え５２が配置されている。日車押え５２は、板金の打抜き加工又は樹脂の一体成形等により形成された二つのバネ部５３，５４を備える。バネ部５３は、図１や図３からわかるように、バネ本体部として働くアーム部５３ａの先端に位置するほぼリング状の保持部５３ｂにおいて、支持案内部材としての案内ブシュ６０をその小径軸部６１（図７〜図９参照）で支える。従って、Ａ方向に対してほぼ直角な方向に延びたバネ部５３の先端の保持部５３ｂによって支持された案内ブシュ６０は、図１等からわかるように、バネ部５３の基端部５３ｃのまわりでＤ１，Ｄ２方向に揺動可能であり、実際上、Ａ１，Ａ２方向に弾性的に変位可能である。同様に、バネ部５４は、バネ本体部として働くアーム部５４ａの先端に位置する保持部５４ｂにおいて、支後述のカレンダ修正車６７の軸部６７ａの一端を支える。従って、バネ部５４の先端の保持部５４ｂによって一端が支持されたカレンダ修正車６７の軸部６７ａは、その他端が遊嵌された地板４の溝４ａ（図４〜図６）に沿って、バネ部５４の基端部５４ｃのまわりでＦ１，Ｆ２方向に揺動可能である。バネ部５４もＦ１，Ｆ２方向の揺動に際して日車押え５２の周囲の部分と干渉しないように、基端部５４ｃの折曲部５４ｄで内向きに折り曲げられている。   As can be seen from FIGS. 4 to 6 in addition to FIGS. 1 to 3, the date wheel 50 arranged substantially along the inner periphery of the trunk 2 includes engagement teeth 51 on the inner periphery. As can be seen from FIGS. 1 and 3 and FIGS. 7 to 9, a date dial holder 52 is disposed on the dial side of the date dial 50. The date dial holder 52 includes two spring portions 53 and 54 formed by punching a sheet metal or integrally molding a resin. As can be seen from FIGS. 1 and 3, the spring portion 53 is a substantially ring-shaped holding portion 53b located at the tip of an arm portion 53a that functions as a spring main body portion. 61 (see FIGS. 7 to 9). Accordingly, the guide bush 60 supported by the holding portion 53b at the distal end of the spring portion 53 extending in a direction substantially perpendicular to the A direction is around the base end portion 53c of the spring portion 53, as can be seen from FIG. Can swing in the D1 and D2 directions, and can be elastically displaced in the A1 and A2 directions in practice. Similarly, the spring portion 54 supports one end of a shaft portion 67a of a calendar correction wheel 67, which will be described later, at a holding portion 54b positioned at the tip of an arm portion 54a that functions as a spring main body portion. Therefore, the shaft portion 67a of the calendar correction wheel 67, one end of which is supported by the holding portion 54b at the tip of the spring portion 54, is along the groove 4a (FIGS. 4 to 6) of the base plate 4 in which the other end is loosely fitted. It can be swung in the F1 and F2 directions around the base end portion 54c of the spring portion 54. The spring portion 54 is also bent inward at the bent portion 54d of the base end portion 54c so as not to interfere with the surrounding portion of the date dial presser 52 when swinging in the directions F1 and F2.

図７〜図９からわかるように、案内ブシュ６０は、小径軸部６１に加えて大径軸部ないしフランジ状大径部６２と該大径部６２の端面ないし表面６２ａから軸線方向に突出した係合突起部６３とを有する。係合突起部６３は、図５等からわかるように、部分円筒状周面６３ａと（平面図でみて）弦として表わされ該外周面６３ａの両縁を規定する半径方向内側の平面部６３ｂとにより規定される側面を有する。   As can be seen from FIGS. 7 to 9, the guide bush 60 protrudes in the axial direction from the large-diameter shaft portion or flange-like large-diameter portion 62 and the end surface or surface 62 a of the large-diameter portion 62 in addition to the small-diameter shaft portion 61. And an engaging protrusion 63. As can be seen from FIG. 5 and the like, the engaging protrusion 63 is represented as a partial cylindrical peripheral surface 63a and a chord (as viewed in plan view) as a chord, and defines a flat inner portion 63b that defines both edges of the outer peripheral surface 63a. And has a side defined by

図７〜図９からわかるように、案内ブシュ６０の突起部６３は、つづみ車４０の両端大径部４１，４２と小径部４６とにより規定される環状凹部４７内に突出して該凹部４７に遊嵌され、つづみ車４０が基準位置Ｓｔ０及び一段目位置Ｓｔ１にある状態Ｓ０（図７）及びＳ１（図８）では、案内ブシュ６０は、突起部５２が大径部４１，４２の内面４１ａ，４２ａから実際上離れた状態で凹部４７内に位置するような基準位置Ｓａ０及び一段目位置Ｓａ１を採る。なお、つづみ車４０が一段目位置Ｓｔ１に達した際に大径部４１の内面４１ａに周面部６３ａで丁度当接するようになっていてもよい。つづみ車４０が、その一段目位置Ｓｔ１から二段目位置Ｓｔ２に移動する際には、突起部６３が周面部６３ａでつづみ車４０の大径部４１の内面４１ａに当接し、該つづみ車４０のＡ２方向変位に応じて、バネ部５３の弾性保持力に抗してＡ２方向に押されるので、案内ブシュ６０がＡ２方向に変位される。従って、つづみ車４０が二段目位置Ｓｔ２に達する状態Ｓ２では、案内ブシュ６０もその二段目位置Ｓａ２に移動される。   As can be seen from FIGS. 7 to 9, the projection 63 of the guide bush 60 protrudes into the annular recess 47 defined by the large-diameter portions 41 and 42 and the small-diameter portion 46 at both ends of the clutch wheel 40. In the state S0 (FIG. 7) and S1 (FIG. 8) in which the pulley wheel 40 is loosely fitted to the reference position St0 and the first stage position St1, the guide bush 60 has the protrusion 52 of the large-diameter portions 41, 42. A reference position Sa0 and a first-stage position Sa1 that are located in the recess 47 in a state of being actually separated from the inner surfaces 41a and 42a are adopted. It should be noted that the peripheral surface portion 63a may just come into contact with the inner surface 41a of the large diameter portion 41 when the handwheel 40 reaches the first stage position St1. When the handwheel 40 moves from the first-stage position St1 to the second-stage position St2, the protrusion 63 abuts on the inner surface 41a of the large-diameter portion 41 of the wheel 40 at the peripheral surface 63a. The guide bush 60 is displaced in the A2 direction because it is pushed in the A2 direction against the elastic holding force of the spring portion 53 in accordance with the displacement in the A2 direction of the wheel 40. Accordingly, in the state S2 where the pinwheel 40 reaches the second stage position St2, the guide bush 60 is also moved to the second stage position Sa2.

案内ブシュ６０の小径軸部６１には、カレンダ修正機構の入力側歯車としての第一カレンダ修正伝え車６５が回転自在に支持されている。この第一カレンダ修正伝え車６５は、内面に歯車部６５ａを備える。第一カレンダ修正伝え車６５の歯車部６５ａは、つづみ車４０が基準位置Ｓｔ０にある状態Ｓ０（図７）では、つづみ車４０の歯車部４４から離れており、つづみ車４０が一段目位置Ｓｔ１に達した状態Ｓ１（図８）では、つづみ車４０の歯車部４４に噛合する。つづみ車４０が一段目位置Ｓｔ１と二段目位置Ｓｔ２との間に位置する場合、第一カレンダ修正伝え車６５の歯車部６５ａはつづみ車４０の歯車部４４に対して噛合状態に保たれる。但し、例えば、つづみ車４０が一段目位置Ｓｔ１から所定長だけＡ２方向に移動して初めてつづみ車４０の大径部４１が案内ブシュ６０の係合突起部６３に当接すると共に該所定長のＡ２方向移動の間につづみ車４０の歯車部４４と第一カレンダ修正伝え車６５の歯車部６５ａとの噛合が解除されるようにしておくことにより、つづみ車４０が一段目位置Ｓｔ１と二段目位置Ｓｔ２との間に位置する状態及び二段目位置に達した状態Ｓ２では、第一カレンダ修正伝え車６５とつづみ車４０の歯車部４４との噛合が解除されるようになっていてもよい。   A first calendar correction transmission wheel 65 as an input side gear of the calendar correction mechanism is rotatably supported on the small diameter shaft portion 61 of the guide bush 60. The first calendar correction transmission wheel 65 includes a gear portion 65a on the inner surface. The gear portion 65a of the first calendar correction transmission wheel 65 is separated from the gear portion 44 of the pinion wheel 40 in the state S0 (FIG. 7) in which the pinion wheel 40 is at the reference position St0. In the state S1 (FIG. 8) in which the eye position St1 is reached, it meshes with the gear portion 44 of the pinion wheel 40. When the pinion wheel 40 is located between the first step position St1 and the second step position St2, the gear portion 65a of the first calendar correction transmission wheel 65 is kept in mesh with the gear portion 44 of the pinion wheel 40. Be drunk. However, for example, the large-diameter portion 41 of the pinion wheel 40 is brought into contact with the engagement protrusion 63 of the guide bush 60 only when the pinion wheel 40 is moved in the A2 direction by a predetermined length from the first stage position St1, and the predetermined length is reached. During the movement in the A2 direction, the engagement between the gear portion 44 of the pulley wheel 40 and the gear portion 65a of the first calendar correction transmission wheel 65 is released, whereby the pulley wheel 40 is moved to the first stage position St1. In the state located between the first stage position St2 and the second stage position S2, the engagement between the first calendar correction transmission wheel 65 and the gear portion 44 of the pulley wheel 40 is released. It may be.

時計１は、日修正に関して、更に、第二カレンダ修正伝え車６６とカレンダ修正車６７とを有する。従って、この例では、カレンダ修正機構は、第一及び第二カレンダ修正伝え車６５，６６とカレンダ修正車６７とからなる。第二カレンダ修正伝え車６６は、案内ブシュ６０がその基準位置Ｓａ０にある状態（巻真０段目）Ｓ０及び一段目位置Ｓａ１にある状態（巻真一段目）Ｓ１では、第一カレンダ修正伝え車６５の歯車部６５ｂと噛合状態に保たれるけれども、案内ブシュ６０がその二段目位置Ｓａ２にある状態Ｓ２（巻真二段目）では第一カレンダ修正伝え車６５がＡ２方向に移動されるので、第一カレンダ修正伝え車６５との噛合が解除される。なお、案内ブシュ６０がその二段目位置Ｓａ２にある状態（巻真二段目）Ｓ２では、第二カレンダ修正伝え車６６と実質的に常時噛合状態に保たれる。但し、カレンダ修正車６７は、バネ部５４によって該バネ部５４の基端部５４ｃのまわりでＦ１，Ｆ２方向に（溝４ａに沿うように）揺動可能に支持されているので、案内ブシュ６０がその一段目位置Ｓａ１にあってＥ１方向の回転トルクが第二カレンダ修正伝え車６６から伝達される状態（巻真一段目）Ｓ１に限り、バネ部５４のバネ力に抗してＦ１方向に揺動されて日車５０の係合歯５１に係合され、日車５０をＪ１方向に回転させる。   The timepiece 1 further includes a second calendar correction transmission wheel 66 and a calendar correction wheel 67 for date correction. Therefore, in this example, the calendar correction mechanism includes the first and second calendar correction transmission wheels 65 and 66 and the calendar correction wheel 67. The second calendar correction transmission wheel 66 is in a state where the guide bush 60 is in its reference position Sa0 (winding zero stage 0) S0 and in a first stage position Sa1 (winding winding first stage) S1, the first calendar correction transmission wheel 66. Although kept in mesh with the gear portion 65b of the wheel 65, the first calendar correction transmission wheel 65 is moved in the A2 direction in the state S2 (second winding stage) where the guide bush 60 is in the second position Sa2. Therefore, the mesh with the first calendar correction transmission wheel 65 is released. In the state where the guide bush 60 is at the second stage position Sa2 (second winding stage) S2, the second calendar correction transmission wheel 66 is substantially always kept in mesh. However, the calendar correction wheel 67 is supported by the spring portion 54 so as to be swingable around the base end portion 54c of the spring portion 54 in the F1 and F2 directions (along the groove 4a). Is in the first position Sa1 and the rotational torque in the E1 direction is transmitted from the second calendar correction transmission wheel 66 (first winding stage) S1, in the F1 direction against the spring force of the spring portion 54. It is swung and engaged with the engagement teeth 51 of the date dial 50, and the date dial 50 is rotated in the J1 direction.

なお、日車５０の係合歯５１には、更に、日回し車５５の日回し爪５６が係合可能である。   In addition, the date driving claw 56 of the date driving wheel 55 can be further engaged with the engagement tooth 51 of the date dial 50.

日の裏車８０は、例えば図９からわかるように、時車として働く筒車７１の筒歯車部７２にかな部８１で噛合され及び分車として働く二番車７３の二番かな７４に歯車部８２で噛合されている。日の裏車８０の歯車部８２には、つづみ車４０がその二段目位置Ｓｔ２に達した状態Ｓ２において、甲歯４５が噛合する。つづみ車４０が位置Ｓｔ０やＳｔ１にある状態（巻真０段目や巻真一段目）Ｓ０やＳ１では、甲歯４５と日の裏車８０の歯車部８２との噛合は解除されている。   As can be seen from FIG. 9, for example, the minute wheel 80 is meshed with the pinion gear portion 72 of the hour wheel 71 serving as the hour wheel at the pinion portion 81 and is geared to the second pinion 74 of the second wheel 73 acting as the minute wheel. The portion 82 is engaged. The instep 45 is engaged with the gear portion 82 of the minute wheel 80 in the state S2 in which the clutch wheel 40 has reached the second stage position St2. In the state where the pinion wheel 40 is at the position St0 or St1 (the winding stem 0 stage or the winding stem 1 stage) S0 or S1, the meshing of the instep 45 and the gear portion 82 of the minute wheel 80 is released. .

次に、以上の如く構成された時計１において、巻真２０を操作する場合の動作について、説明する。   Next, an operation when the winding stem 20 is operated in the timepiece 1 configured as described above will be described.

巻真２０が、Ａ２方向に奥まで押し込まれた基準位置Ｓｍ０にある時計１の通常使用状態ないし基準状態（巻真０段目）Ｓ０では、図１や図４や図７に示したように、つづみ車４０も基準位置Ｓｔ０にあり、つづみ車４０の乙歯４３がきち車３２に噛合している。従って、巻真２０をＢ１方向に回転させる際に、巻真２０の回転がつづみ車４０及びきち車３２を介して、丸穴車１１に伝達され、更に、揺動丸穴車１２、二番伝え車１５及び角穴車１７を介して、ぜんまいが巻上げられる。   As shown in FIGS. 1, 4, and 7, in the normal use state or the reference state (the winding stem 0th stage) S0 of the timepiece 1 in which the winding stem 20 is in the reference position Sm0 that is pushed all the way in the A2 direction. The pinion wheel 40 is also at the reference position St0, and the tooth 43 of the pinion wheel 40 is meshed with the tooth wheel 32. Therefore, when the winding stem 20 is rotated in the B1 direction, the rotation of the winding stem 20 is transmitted to the round hole wheel 11 via the pinion wheel 40 and the chime wheel 32, and further, the swing round hole wheel 12, The mainspring is wound up through the transmission wheel 15 and the square hole wheel 17.

なお、この基準状態Ｓ０では、つづみ車４０と、第一カレンダ修正伝え車６５や日の裏車８０との係合（噛合）は解除されているので、つづみ車４０の回転は、日修正や時刻修正には影響を及ぼさない。   In this reference state S0, the engagement (meshing) of the pinion wheel 40 with the first calendar correction transmission wheel 65 and the minute wheel 80 is released, so the rotation of the pinion wheel 40 It does not affect the correction or time correction.

一方、巻真２０がＡ１方向に引出されて一段引出位置Ｓｍ１に位置決めされると、つづみ車４０もおしどり３１やかんぬき３３によってＡ２方向に変位され一段目位置Ｓｔ１に位置決めされ、時計１が状態Ｓ１（巻真一段目）に設定される。この状態Ｓ１では、図２や図５や図８に示したように、巻真２０の長手方向Ａに沿って奥向きＡ２に変位されたつづみ車４０が大径部４１の外周歯車部４４で第一カレンダ修正伝え車６５に噛合する。従って、巻真２０をＢ２方向に回転させる際に、巻真２０のＢ２方向の回転がつづみ車４０から第一カレンダ修正伝え車６５にＧ１方向回転として伝達され、更に、該第一カレンダ修正伝え車６５に噛合した第二カレンダ修正伝え車６６のＨ１方向回転に従ってカレンダ修正車６７が噛合部においてＥ１方向のトルクを受け、カレンダ修正車６７の軸６７ａがバネ５４のバネ力に抗して溝４ａに沿ってＦ１方向に揺動されて、カレンダ修正車６７の係合歯ないし係合爪６７ｂが日車５０の係合歯５１に係合する。その結果、カレンダ修正車６７のＥ１方向回転に伴って日車５０がＪ１方向に回転され、日修正が行われ得る。なお、日以外のカレンダ修正が同様に行われるようにしておいてもよい。   On the other hand, when the winding stem 20 is pulled out in the A1 direction and positioned in the first-stage extraction position Sm1, the pinion wheel 40 is also displaced in the A2 direction by the setting lever 31 and the crown 33, and is positioned in the first-stage position St1. It is set to S1 (winding first stage). In this state S 1, as shown in FIGS. 2, 5, and 8, the pinion wheel 40 displaced in the back direction A <b> 2 along the longitudinal direction A of the winding stem 20 is the outer peripheral gear portion 44 of the large-diameter portion 41. To mesh with the first calendar correction transmission wheel 65. Therefore, when the winding stem 20 is rotated in the B2 direction, the rotation of the winding stem 20 in the B2 direction is transmitted from the staple wheel 40 to the first calendar correction transmission wheel 65 as the G1 direction rotation, and further, the first calendar correction is performed. As the second calendar correction transmission wheel 66 meshed with the transmission wheel 65 rotates in the H1 direction, the calendar correction wheel 67 receives torque in the E1 direction at the meshing portion, and the shaft 67a of the calendar correction wheel 67 resists the spring force of the spring 54. By swinging in the F1 direction along the groove 4a, the engagement teeth or the engagement claws 67b of the calendar correction wheel 67 are engaged with the engagement teeth 51 of the date dial 50. As a result, the date dial 50 can be rotated in the J1 direction as the calendar correction wheel 67 rotates in the E1 direction, and the date correction can be performed. The calendar correction other than the day may be performed in the same manner.

ここでは、つづみ車４０が一段目位置Ｓｔ１に達した際に、単に、つづみ車４０の歯部４４が第一カレンダ修正伝え車６５に噛合するとして説明したけれども、第一カレンダ修正伝え車６５と第二カレンダ修正伝え車６６との噛合が保たれ得る限り、つづみ車４０が一段目位置Ｓｔ１に達する前につづみ車４０の大径部４１が案内ブシュ６０に当接しつづみ車４０が一段目位置Ｓｔ１に位置決めされる際には、該案内ブシュ６０を若干Ａ２方向に変位させるようになっていてもよい。   Here, it has been described that the tooth portion 44 of the pinion wheel 40 is simply meshed with the first calendar correction transmission wheel 65 when the pinion wheel 40 reaches the first stage position St1, but the first calendar correction transmission wheel As long as the meshing of 65 and the second calendar correction transmission wheel 66 can be maintained, the large-diameter portion 41 of the pinion wheel 40 abuts against the guide bush 60 before the pinion wheel 40 reaches the first stage position St1. When 40 is positioned at the first stage position St1, the guide bush 60 may be slightly displaced in the A2 direction.

なお、巻真一段目状態Ｓ１では、つづみ車４０のＡ２方向変位に伴いつづみ車４０の乙歯４３ときち車３２との噛合は解除されており、また、つづみ車４０と日の裏車８０との噛合も生じていない。従って、つづみ車４０の回転は、ぜんまいの巻上げや時刻修正には影響を及ぼさない。   In the winding true first stage state S1, the meshing of the tooth wheel 40 with the tooth 43 and the wheel 32 of the tooth wheel 40 is released along with the displacement of the wheel 40 in the A2 direction. There is no meshing with the back wheel 80. Therefore, the rotation of the hour wheel 40 does not affect the winding of the mainspring or the time adjustment.

巻真２０がＡ１方向に更に引出されて二段引出位置Ｓｍ２に位置決めされると、つづみ車４０もおしどり３１やかんぬき３３によってＡ２方向に更に変位され二段目位置Ｓｔ２に位置決めされ、時計１が状態Ｓ２（巻真二段目）に設定される。この状態Ｓ２では、図３や図６や図９に示したように、巻真２０の長手方向Ａに沿って奥向きＡ２に変位されたつづみ車４０がその大径部４２の端面にある甲歯４５で日の裏車８０の歯車部８２に直接噛合する。従って、巻真２０のＢ１又はＢ２方向の回転に応じて、日の裏車８０が対応する向きに回転され、該日の裏車８０の回転に応じて、分車７３及び筒車７１が対応する方向に回転され、分針及び時針の位置が調整される。   When the winding stem 20 is further pulled in the A1 direction and positioned at the second-stage extraction position Sm2, the pinion wheel 40 is further displaced in the A2 direction by the setting lever 31 and the crown 33, and is positioned at the second-stage position St2. Is set to the state S2 (second winding step). In this state S2, as shown in FIG. 3, FIG. 6, and FIG. 9, the pinion wheel 40 displaced in the back direction A2 along the longitudinal direction A of the winding stem 20 is on the end face of the large diameter portion 42. The upper teeth 45 directly mesh with the gear portion 82 of the minute wheel 80. Accordingly, according to the rotation of the winding stem 20 in the B1 or B2 direction, the minute wheel 80 is rotated in the corresponding direction, and according to the rotation of the minute wheel 80, the minute wheel 73 and the hour wheel 71 correspond. The position of the minute hand and hour hand is adjusted.

なお、つづみ車４０が一段目位置Ｓｔ１から二段目位置Ｓｔ２に向かってＡ２方向に移動される際、つづみ車４０の大径部４１が案内ブシュ６０に当接して該案内ブシュ６０をバネ５３のバネ力に抗してＡ２方向に押し、一段目位置Ｓａ１から二段目位置Ｓａ２にＤ１方向に揺動変位させるので、案内ブシュ６０に支えられた第一カレンダ修正伝え車６５もＤ１方向に変位されて第一カレンダ修正伝え車６５と第二カレンダ修正伝え車６６との噛合が解除される。なお、つづみ車４０ときち車３２との噛合は解除されたままである。従って、つづみ車４０の回転は、日修正やぜんまいの巻上げには影響を及ぼさない。   When the pinion wheel 40 is moved in the A2 direction from the first step position St1 to the second step position St2, the large-diameter portion 41 of the pinion wheel 40 abuts on the guide bushing 60 and the guide bushing 60 is moved. The spring 53 is pushed in the A2 direction against the spring force, and is displaced in the D1 direction from the first-stage position Sa1 to the second-stage position Sa2, so that the first calendar correction transmission wheel 65 supported by the guide bush 60 is also D1. The first calendar correction transmission wheel 65 and the second calendar correction transmission wheel 66 are disengaged by being displaced in the direction. In addition, the meshing with the pinion wheel 40 and the wheel 32 is still released. Therefore, the rotation of the hour wheel 40 does not affect date correction or winding of the mainspring.

以上において、状態Ｓ０，Ｓ１，Ｓ２の夫々は、巻真２０の位置Ｓｍ０，Ｓｍ１，Ｓｍ２に依存し、且つ巻真２０が位置Ｓｍ１にＡ１方向に達したかＡ２方向に達したかには依存しないから、状態Ｓ０，Ｓ１，Ｓ２に関する以上の説明は、巻真２０をＡ２方向に押込んだ場合にも同様に当てはまる。   In the above, each of the states S0, S1, S2 depends on the position Sm0, Sm1, Sm2 of the winding stem 20, and depends on whether the winding stem 20 has reached the position Sm1 in the A1 direction or the A2 direction. Therefore, the above description regarding the states S0, S1, and S2 also applies to the case where the winding stem 20 is pushed in the A2 direction.

なお、日回し車５５による日車５０の回転を実際上妨げない限り、カレンダ修正車６７の軸が一定位置にあって係合歯６７ｂが日車５０の係合歯５１に係合可能な状態に保たれていてもよい。   As long as the rotation of the date indicator 50 by the date indicator driving wheel 55 is not substantially prevented, the shaft of the calendar correction wheel 67 is in a fixed position and the engagement teeth 67b can be engaged with the engagement teeth 51 of the date indicator 50. May be kept.

以上においては、時計１が手巻式のぜんまいにより駆動される機械式時計であるとして説明したけれども、回転錘の揺動ないし往復回動でぜんまいが巻上げられる自動巻き式の機械式時計や電池等で駆動される電子時計においても、巻真の一段引出位置Ｓｍ１及び二段引出位置Ｓｍ２は同様に規定され得るから、状態Ｓ１，Ｓ２に関する説明は、そのまま当てはまる。   In the above description, the timepiece 1 has been described as a mechanical timepiece driven by a hand-wound mainspring.
