Description

本発明は、太陽電池付電子時計に関する。   The present invention relates to an electronic timepiece with a solar cell.

従来、地板の表側に太陽電池受けリングを配置し、この太陽電池受けリングの表側に、太陽電池および透光性の文字板を配置した太陽電池付時計が知られている（例えば、特許文献１参照）。
この太陽電池付時計では、太陽電池受けリングの表面に、リング外周に沿って約９０度間隔で時計表面側に突出するフック部を形成し、太陽電池受けリングおよびフック部間で前記太陽電池および文字板を挟んで固定していた。すなわち、太陽電池受けリングは、文字板受けリングを兼用していた。
そして、前記フック部は文字板上に露出するため、文字板の外周に沿ってダイヤルリングを配置し、フック部を被覆していた。 Conventionally, a solar cell timepiece is known in which a solar cell receiving ring is arranged on the front side of the ground plate, and a solar cell and a translucent dial are arranged on the front side of the solar cell receiving ring (for example, Patent Document 1). reference).
In this timepiece with a solar cell, a hook portion is formed on the surface of the solar cell receiving ring so as to protrude toward the surface of the watch at intervals of about 90 degrees along the outer periphery of the ring, and the solar cell and the solar cell It was fixed across the dial. That is, the solar battery receiving ring also serves as the dial receiving ring.

特開平１０−２３９４５３号公報Japanese Patent Laid-Open No. 10-239453

前記太陽電池付電子時計では、文字板の見切り径、つまりダイヤルリングの内径は、前記フック部の位置によって制限される。すなわち、フック部によって見切り径に制約が生じるという問題があった。
このため、時計のモデルバリエーションを広げることができないという問題があった。 In the electronic timepiece with solar cell, the parting diameter of the dial plate, that is, the inner diameter of the dial ring is limited by the position of the hook portion. That is, there is a problem that the parting diameter is restricted by the hook portion.
For this reason, there has been a problem that the model variations of the watch cannot be expanded.

本発明の目的は、文字板の見切り径の制約を無くしてモデルバリエーションを広げることができる太陽電池付電子時計を提供することにある。   An object of the present invention is to provide an electronic timepiece with a solar cell that can expand the model variation by eliminating the restriction on the parting diameter of the dial.

本発明の太陽電池付電子時計は、基材および前記基材上に形成される受光部を有する太陽電池と、前記太陽電池の時計表側に配置された透光性の文字板と、前記文字板を保持する文字板受けリング部材と、前記太陽電池の裏面に固定された太陽電池案内板と、を備え、前記文字板受けリング部材は、前記文字板受けリング部材の表面に開口された開口部内に形成されたフック係止部を備え、前記太陽電池案内板は、前記太陽電池の受光部よりも外周側に突出して形成される突出部と、前記突出部から前記文字板受けリング部材の前記開口部内に向かって突出して形成されて前記フック係止部に係止されるフック部とを備え、前記太陽電池の基材は、前記太陽電池案内板および前記文字板受けリング部材の前記開口部を被覆する被覆部を備えることを特徴とする。   An electronic timepiece with a solar cell of the present invention is a solar cell having a base material and a light receiving portion formed on the base material, a translucent dial plate arranged on the clock face side of the solar cell, and the dial plate And a solar cell guide plate fixed to the back surface of the solar cell, and the dial receiving ring member has an opening in the opening of the dial receiving ring member. A hook engaging portion formed on the solar cell guide plate, the solar cell guide plate protruding from the light receiving portion of the solar cell toward the outer peripheral side, and the protrusion of the dial receiving ring member from the protruding portion. A hook portion that protrudes into the opening and is locked to the hook locking portion, and the solar cell base material is the opening portion of the solar cell guide plate and the dial receiving ring member. With a covering part for covering And wherein the door.

本発明の太陽電池付電子時計では、太陽電池の裏面に太陽電池案内板を、接着剤などを用いて固定し、この太陽電池案内板の突出部から文字板受けリング部材の前記開口部内に向かって、つまり突出部から時計裏面側に向かって突出するフック部を形成している。そして、このフック部を前記開口部内のフック係止部に係止させることで、太陽電池を文字板受けリング部材に取り付けている。
従って、従来のように、文字板受けリング部材の表面にフック部を形成する必要がなく、太陽電池の表面側に出っ張る部材が無い。このため、従来のように、太陽電池の表面側に露出するフック部をダイヤルリングで被覆する必要が無く、見切り径の制約も無くすことができる。よって、文字板のサイズや見切り径のサイズの自由度が高まり、地球環境に与える負荷がより少ない太陽電池付電子時計を腕時計として構成する場合、見切り径の大きなビッグサイズの腕時計から見切り径の小さな女性用の腕時計まで、モデルバリエーションの自由度を高めることができる。 In the electronic timepiece with solar cell of the present invention, a solar cell guide plate is fixed to the back surface of the solar cell using an adhesive or the like, and the projecting portion of the solar cell guide plate is directed into the opening of the dial receiving ring member. That is, a hook portion that protrudes from the protruding portion toward the back side of the watch is formed. The solar battery is attached to the dial receiving ring member by locking the hook portion with the hook locking portion in the opening.
Therefore, unlike the conventional case, there is no need to form a hook portion on the surface of the dial receiving ring member, and there is no member protruding on the surface side of the solar cell. For this reason, it is not necessary to cover the hook part exposed on the surface side of the solar cell with a dial ring as in the prior art, and the restriction of the parting diameter can be eliminated. Therefore, the freedom of the size of the dial and the parting diameter is increased, and when configuring an electronic timepiece with a solar cell that has a smaller load on the global environment as a wristwatch, the watch with a small parting diameter is compared with a big size wristwatch with a large parting diameter. Even women's watches can increase the degree of freedom of model variations.

また、前記文字板受けリング部材のフック部は、太陽電池の受光部よりも外周側に突出する突出部に形成されている。このため、フック部をたとえばピンセットなどで保持し、前記太陽電池および太陽電池案内板を文字板受けリング部材に着脱するための作業を行った場合に、ピンセットなどで太陽電池の受光部を傷つける可能性を低くできる。従って、太陽電池の着脱作業時の作業性も向上できる。
さらに、前記太陽電池の基材に被覆部を設け、この被覆部で前記太陽電池案内板および前記文字板受けリング部材の前記開口部を被覆している。このため、太陽電池案内板や開口部が文字板を介して時計表面側に透けて見えることを防止できる。特に、太陽電池案内板は、ステンレスなどの金属板で構成されて太陽電池とは反射率が大きく異なり、太陽電池で被覆されずに露出すると、太陽電池との見栄えの相違が目立つ。また、開口部も穴であるため、文字板側に露出すると、太陽電池との相違が目立つ。これに対し、本発明では、太陽電池案内板や開口部を、太陽電池の基材の被覆部で被覆しているので、これらの部位が文字板から透けて見えることを防止でき、太陽電池付電子時計の外観を向上できる。 Moreover, the hook part of the said dial receiving ring member is formed in the protrusion part which protrudes in the outer peripheral side rather than the light-receiving part of a solar cell. For this reason, when the hook portion is held with tweezers, for example, and the work for attaching and detaching the solar cell and the solar cell guide plate to the dial receiving ring member is performed, the light receiving portion of the solar cell can be damaged by tweezers. Can be lowered. Therefore, workability at the time of attaching and detaching the solar cell can be improved.
Further, a covering portion is provided on the substrate of the solar cell, and the opening portion of the solar cell guide plate and the dial receiving ring member is covered with the covering portion. For this reason, it can prevent that a solar cell guide plate and an opening part see through to the timepiece surface side through a dial. In particular, the solar cell guide plate is made of a metal plate such as stainless steel, and has a significantly different reflectance from the solar cell. When exposed without being covered with the solar cell, the difference in appearance from the solar cell is conspicuous. Moreover, since an opening part is also a hole, when exposed to the dial side, the difference with a solar cell is conspicuous. On the other hand, in the present invention, since the solar cell guide plate and the opening are covered with the covering portion of the solar cell base material, it is possible to prevent these parts from being seen through the dial, and with the solar cell. The appearance of the electronic watch can be improved.

本発明の太陽電池付電子時計では、前記太陽電池案内板の裏面側に配置されるムーブメントは、前記ムーブメントの平面中心位置から前記ムーブメント外周までの長さが、他の外周面よりも短いサイドカット部を有し、前記文字板受けリング部材の表面には、前記文字板を固定する文字板固定部が設けられ、前記フック部は、前記文字板受けリング部材の周方向における配置位置が、前記サイドカット部および前記文字板固定部と異なる位置に設定されていることが好ましい。   In the electronic timepiece with solar cell of the present invention, the movement disposed on the back side of the solar cell guide plate is a side cut in which the length from the plane center position of the movement to the outer periphery of the movement is shorter than the other outer peripheral surface. A dial fixing part for fixing the dial is provided on the surface of the dial receiving ring member, and the hook portion is arranged in the circumferential direction of the dial receiving ring member, It is preferable that it is set at a position different from the side cut part and the dial plate fixing part.

本発明によれば、前記文字板受けリング部材のフック部の配置位置を、前記文字板受けリング部材の周方向において前記サイドカット部や文字板固定部と異なる位置としているので、前記フック部をサイドカット部よりも時計外周側にずらして配置したり、文字板固定部をフック部の外周側にずらして配置する必要がない。
このため、ムーブメントや太陽電池、文字板が配置される時計のケース外径の大型化を防ぐことができる。また、前記ムーブメントのサイドカット部を、時計文字板の３時および９時位置側に形成した場合、時計のケースにおける３時−９時方向の幅つまり時計の横幅の大型化を防止できる。 According to the present invention, the hook portion of the dial receiving ring member is disposed at a position different from the side cut portion and the dial fixing portion in the circumferential direction of the dial receiving ring member. There is no need to shift the dial to the outer peripheral side of the watch from the side cut part, or to shift the dial fixing part to the outer peripheral side of the hook part.
For this reason, the enlargement of the case outer diameter of the timepiece in which the movement, the solar battery, and the dial are arranged can be prevented. Further, when the side cut portions of the movement are formed on the side of the 3 o'clock and 9 o'clock positions of the timepiece dial, it is possible to prevent an increase in the width of the timepiece case in the 3 o'clock to 9 o'clock direction, that is, the lateral width of the timepiece.

本発明の太陽電池付電子時計では、前記文字板受けリング部材の表面には、前記開口部に近接して設けられた太陽電池位置決め部が設けられ、前記太陽電池の基材の被覆部は、前記太陽電池位置決め部に位置決めされる係合部を備えることが好ましい。   In the electronic timepiece with solar cell of the present invention, the surface of the dial receiving ring member is provided with a solar cell positioning portion provided close to the opening, and the covering portion of the base material of the solar cell is: It is preferable to include an engaging portion positioned on the solar cell positioning portion.

本発明によれば、文字板受けリング部材の表面において、前記開口部および太陽電池位置決め部が近接して設けられている。このため、太陽電池案内板の突出部に形成されるフック部と、太陽電池の基材の被覆部に形成される係合部とを近接して設けることができる。従って、太陽電池の受光部の外周から突出して設けられる前記フック部および係合部を近くに配置できるので、基材の被覆部の面積を最小限に抑制できる。従って、太陽電池の面積を最小化でき、太陽電池のコストを低減できる。   According to the present invention, the opening and the solar cell positioning portion are provided close to each other on the surface of the dial receiving ring member. For this reason, the hook part formed in the protrusion part of a solar cell guide plate and the engaging part formed in the coating | coated part of the base material of a solar cell can be provided closely. Therefore, since the hook part and the engaging part provided so as to protrude from the outer periphery of the light receiving part of the solar cell can be disposed close to each other, the area of the covering part of the base material can be minimized. Therefore, the area of the solar cell can be minimized, and the cost of the solar cell can be reduced.

本発明の太陽電池付電子時計では、前記太陽電池位置決め部は、前記文字板受けリング部材の表面に突出する突起により構成され、前記太陽電池の前記係合部は、前記突起に係合する係合溝で構成され、前記太陽電池案内板の突出部は、前記突起に係合する係合溝を備えることが好ましい。   In the solar cell-equipped electronic timepiece of the invention, the solar cell positioning portion is constituted by a protrusion protruding on the surface of the dial receiving ring member, and the engaging portion of the solar cell is engaged with the protrusion. It is preferable that the protrusion portion of the solar cell guide plate includes an engaging groove that engages with the protrusion.

太陽電池位置決め部を突起（ダボ）で構成し、この突起に係合する係合溝（係合部）を太陽電池の基材だけでなく、太陽電池案内板の突出部にも形成している。このため、太陽電池の基材を合成樹脂製のフィルムで構成した場合でも、ステンレスなどの金属材で構成できる太陽電池案内板が積層されて前記係合溝を構成するため、前記係合溝の強度を高めることができる。従って、太陽電池案内板が固定された太陽電池を、文字板受けリング部材の突起（太陽電池位置決め部）に強固に取り付けることができる。   The solar cell positioning portion is constituted by a protrusion (dough), and the engaging groove (engaging portion) that engages with the protrusion is formed not only on the solar cell base material but also on the protruding portion of the solar cell guide plate. . For this reason, even when the base material of the solar cell is formed of a synthetic resin film, a solar cell guide plate that can be formed of a metal material such as stainless steel is laminated to form the engagement groove. Strength can be increased. Therefore, the solar cell to which the solar cell guide plate is fixed can be firmly attached to the protrusion (solar cell positioning portion) of the dial receiving ring member.

本発明の太陽電池付電子時計では、前記文字板受けリング部材の表面側の色は、前記太陽電池の色と同系色であることが好ましい。
本発明によれば、文字板受けリング部材の表面側の色を、太陽電池の色と同系色にしたので、太陽電池および文字板受けリング部材の色調を合わせることができる。このため、文字板受けリング部材に対する色調の差によって、太陽電池の外形が文字板から透けて見えることを防止でき、時計の文字板を見た際の意匠を向上できる。 In the solar cell-attached electronic timepiece of the invention, it is preferable that the color of the surface side of the dial receiving ring member is similar to the color of the solar cell.
According to the present invention, since the color on the surface side of the dial plate receiving ring member is the same color as the color of the solar cell, the color tone of the solar cell and the dial plate receiving ring member can be matched. For this reason, it is possible to prevent the outer shape of the solar cell from being seen through the dial due to the difference in color tone with respect to the dial receiving ring member, and it is possible to improve the design when the dial of the watch is viewed.

フック部４９は、図６にも示すように、太陽電池案内板４５から折曲されたＬ字状の板部で構成されている。すなわち、フック部４９は、太陽電池案内板４５からムーブメント２側に突出する突出部４９１と、突出部４９１の先端から側方に延出された係止部４９２とを備える。   As shown in FIG. 6, the hook portion 49 is configured by an L-shaped plate portion bent from the solar cell guide plate 45. That is, the hook portion 49 includes a protruding portion 491 that protrudes from the solar cell guide plate 45 toward the movement 2 and a locking portion 492 that extends laterally from the tip of the protruding portion 491.

そして、太陽電池案内板４５の係合溝４７や、フック部４９が形成された突出部４６は、図４，５に示すように、太陽電池４の基材４１の被覆部４３で被覆されており、文字板５側から視認できないように構成されている。   And the engaging groove 47 of the solar cell guide plate 45 and the protrusion part 46 in which the hook part 49 was formed are coat | covered with the coating | coated part 43 of the base material 41 of the solar cell 4, as shown in FIG. The dial 5 is not visible from the side.

〔文字板の構成〕
文字板５は、透光性の材料により、図１、２に示すように、太陽電池４の受光部４２全体を覆う大きさに形成されている。なお、文字板５は、少なくとも受光部４２全体を覆う大きさであればよく、前記文字板受けリング部材３よりも大きく形成してもよい。
この文字板５は、外周端縁から径方向に延出する４つの延出部５１と、各延出部５１に平面視コ字状に切り欠き形成される２つの第１係合部５２、及び平面視半円形状に切り欠き形成される２つの第２係合部５３とを備える。
文字板５は、少なくとも延出部５１が、文字板受けリング部材３の上面３０に載置されることで、文字板受けリング部材３に支持される。
第１係合部５２は第１文字板固定部３３に嵌合され、第２係合部５３は第２文字板固定部３４に嵌合する。これにより、文字板５は、文字板受けリング部材３に対して周方向に位置決め固定される。 [Configuration of dial plate]
As shown in FIGS. 1 and 2, the dial plate 5 is formed of a translucent material so as to cover the entire light receiving portion 42 of the solar cell 4. In addition, the dial 5 should just be a magnitude | size which covers at least the whole light-receiving part 42, and may be formed larger than the said dial receiving ring member 3. FIG.
The dial plate 5 includes four extending portions 51 that extend in the radial direction from the outer peripheral edge, and two first engaging portions 52 that are formed by notching each extending portion 51 in a U shape in plan view. And two second engaging portions 53 that are cut out in a semicircular shape in plan view.
The dial plate 5 is supported by the dial plate receiving ring member 3 by placing at least the extending portion 51 on the upper surface 30 of the dial plate receiving ring member 3.
The first engagement portion 52 is fitted to the first dial plate fixing portion 33, and the second engagement portion 53 is fitted to the second dial plate fixing portion 34. As a result, the dial 5 is positioned and fixed in the circumferential direction with respect to the dial receiving ring member 3.

なお、ムーブメント２は、図１に示すように、文字板５における３時の目盛位置側と、９時の目盛位置側がサイドカット部２Ａ、２Ｂとされている。
そして、文字板受けリング部材３の円周方向における開口部３７の形成位置つまり前記太陽電池案内板４５のフック部４９の形成位置は、前記サイドカット部２Ａ、２Ｂの形成位置および第１文字板固定部３３、第２文字板固定部３４の形成位置のいずれとも異なる位置に設定されている。
さらに、太陽電池案内板４５のフック部４９は、太陽電池位置決め部３５に係合する係合溝４４に近接して形成されている。このため、文字板受けリング部材３の開口部３７は、太陽電池位置決め部３５に近接して形成されている。従って、文字板受けリング部材３の外周方向（円周方向）において、前記係合溝４４、太陽電池位置決め部３５と、フック部４９、開口部３７間に、前記サイドカット部２Ａ、２Ｂや各文字板固定部３３、３４が配置されることがないように設計されている。 In the movement 2, as shown in FIG. 1, the 3 o'clock scale position side and the 9 o'clock scale position side of the dial plate 5 are side cut portions 2A and 2B.
And the formation position of the opening part 37 in the circumferential direction of the dial receiving ring member 3, that is, the formation position of the hook part 49 of the solar cell guide plate 45 is the formation position of the side cut parts 2A, 2B and the first dial. It is set at a position different from any of the formation positions of the fixing portion 33 and the second dial plate fixing portion 34.
Further, the hook portion 49 of the solar cell guide plate 45 is formed close to the engagement groove 44 that engages with the solar cell positioning portion 35. For this reason, the opening 37 of the dial receiving ring member 3 is formed close to the solar cell positioning portion 35. Accordingly, in the outer peripheral direction (circumferential direction) of the dial receiving ring member 3, the side cut portions 2A, 2B, and the like between the engagement groove 44, the solar cell positioning portion 35, the hook portion 49, and the opening portion 37 are provided. It is designed so that the dial fixing portions 33 and 34 are not arranged.

〔時計本体の組み立て〕
次に、図１を参照して、時計本体１０の組み立て方法について説明する。
まず、文字板受けリング部材３でムーブメント２を保持する。この際、ムーブメント２の上方から文字板受けリング部材３をはめ込むとともに、文字板受けリング部材３の支持フック部３２をムーブメント２の底面に引っ掛けるようにして支持する。 [Assembly of the watch body]
Next, a method for assembling the watch body 10 will be described with reference to FIG.
First, the movement 2 is held by the dial receiving ring member 3. At this time, the dial receiving ring member 3 is fitted from above the movement 2, and the support hook portion 32 of the dial receiving ring member 3 is supported by being hooked on the bottom surface of the movement 2.

次に、太陽電池４を文字板受けリング部材３に保持させる。すなわち、太陽電池４の裏面に接着された太陽電池案内板４５のフック部４９を、文字板受けリング部材３のフック係止部３９に係合させる。
具体的には、フック部４９の係止部４９２を開口部３７に配置して、フック係止部３９の傾斜面３９１に当接させ、そのまま太陽電池４を文字板受けリング部材３側に押し込む。
すると、フック部４９の係止部４９２は、傾斜面３９１に案内されて外側に広がり、突出部４９１も弾性変形して外側に湾曲する。
そして、係止部４９２が傾斜面３９１の下端を超えると、弾性変形によって外側に湾曲されていた突出部４９１も元の位置に戻る。このため、係止部４９２は、フック係止部３９の下面側に移動して係止される。
この際、被覆部４３の係合溝４４および太陽電池案内板４５の係合溝４７を太陽電池位置決め部３５に係合させ、太陽電池４の文字板受けリング部材３の周方向に対する位置決めも行う。
以上により、太陽電池４は、係合溝４４，４７が太陽電池位置決め部３５に係合することで、文字板受けリング部材３の周方向に対して位置決めされる。また、太陽電池４の太陽電池案内板４５が太陽電池支持面３１上に載置されることで時計の厚さ方向に対して位置決めされる。さらに、フック部４９がフック係止部３９に係止されることで、太陽電池４が文字板受けリング部材３に保持される。 Next, the solar cell 4 is held by the dial receiving ring member 3. That is, the hook portion 49 of the solar cell guide plate 45 bonded to the back surface of the solar cell 4 is engaged with the hook engaging portion 39 of the dial plate receiving ring member 3.
Specifically, the locking portion 492 of the hook portion 49 is disposed in the opening portion 37 and brought into contact with the inclined surface 391 of the hook locking portion 39, and the solar cell 4 is pushed into the dial receiving ring member 3 side as it is. .
Then, the engaging portion 492 of the hook portion 49 is guided by the inclined surface 391 and spreads outward, and the protruding portion 491 is also elastically deformed and curved outward.
And if the latching | locking part 492 exceeds the lower end of the inclined surface 391, the protrusion part 491 currently curved outside by elastic deformation will also return to the original position. For this reason, the latching | locking part 492 moves to the lower surface side of the hook latching | locking part 39, and is latched.
At this time, the engaging groove 44 of the covering portion 43 and the engaging groove 47 of the solar cell guide plate 45 are engaged with the solar cell positioning portion 35 to position the dial plate ring member 3 of the solar cell 4 in the circumferential direction. .
As described above, the solar cell 4 is positioned with respect to the circumferential direction of the dial receiving ring member 3 by engaging the engaging grooves 44 and 47 with the solar cell positioning portion 35. Further, the solar cell guide plate 45 of the solar cell 4 is positioned on the solar cell support surface 31 so that it is positioned with respect to the thickness direction of the timepiece. Further, the hook portion 49 is locked to the hook locking portion 39, whereby the solar cell 4 is held by the dial plate receiving ring member 3.

次に、文字板５を太陽電池４の表面側から文字板受けリング部材３に保持させる。すなわち、第１係合部５２を文字板受けリング部材３の第１文字板固定部３３に嵌合させ、第２係合部５３を第２文字板固定部３４に嵌合する。これにより、文字板５は、文字板受けリング部材３の上面３０上に載置されて厚み方向に対して位置決めされる。さらに、文字板５は、各係合部５２、５３が、各文字板固定部３３、３４に嵌合することで、文字板受けリング部材３の周方向に対して位置決めされる。
以上により、時計本体１０が組み立てられる。 Next, the dial 5 is held by the dial receiving ring member 3 from the surface side of the solar cell 4. That is, the first engagement portion 52 is fitted to the first dial plate fixing portion 33 of the dial plate receiving ring member 3, and the second engagement portion 53 is fitted to the second dial plate fixing portion 34. Accordingly, the dial plate 5 is placed on the upper surface 30 of the dial plate ring member 3 and positioned in the thickness direction. Furthermore, the dial plate 5 is positioned with respect to the circumferential direction of the dial plate receiving ring member 3 by engaging the engaging portions 52 and 53 with the dial plate fixing portions 33 and 34.
As described above, the watch body 10 is assembled.

上述した本実施形態に係る太陽電池付電子時計１によれば、以下の効果を奏する。
（１）太陽電池４の裏面に接着した太陽電池案内板４５の突出部４６に、時計裏面側に向かって突出するフック部４９を形成し、このフック部４９を、文字板受けリング部材３の開口部３７内に形成されたフック係止部３９に係止させて、太陽電池４を文字板受けリング部材３に取り付けている。
このため、従来のように、文字板受けリング部材３の表面にフック部を形成する必要がなく、太陽電池４の表面側に出っ張る部材を無くすことができる。このため、従来のように、太陽電池４の表面側に露出するフック部をダイヤルリングで被覆する必要が無く、見切り径の制約も無くすことができる。
従って、文字板５のサイズや見切り径のサイズの自由度を向上できる。たとえば、前記実施形態に比べて、文字板受けリング部材３の直径を大きくし、各文字板固定部３３、３４の位置を外周側に移動すれば、太陽電池４やムーブメント２を変更することなく、直径の大きな文字板５を取り付けて見切り径の大きなビッグサイズの腕時計を構成できる。 The electronic timepiece with solar cell 1 according to the above-described embodiment has the following effects.
(1) A hook portion 49 that protrudes toward the back side of the watch is formed on the protruding portion 46 of the solar cell guide plate 45 bonded to the back surface of the solar cell 4, and this hook portion 49 is connected to the dial receiving ring member 3. The solar cell 4 is attached to the dial receiving ring member 3 by being engaged with a hook engaging portion 39 formed in the opening 37.
For this reason, unlike the prior art, it is not necessary to form a hook portion on the surface of the dial receiving ring member 3, and a member protruding on the surface side of the solar cell 4 can be eliminated. For this reason, it is not necessary to cover the hook part exposed on the surface side of the solar cell 4 with a dial ring as in the prior art, and the restriction on the parting diameter can be eliminated.
Therefore, the degree of freedom of the size of the dial 5 and the parting diameter can be improved. For example, compared with the said embodiment, if the diameter of the dial receiving ring member 3 is enlarged and the position of each dial fixing part 33, 34 is moved to the outer peripheral side, without changing the solar cell 4 or the movement 2. By attaching the dial 5 having a large diameter, a big-size wristwatch having a large parting diameter can be configured.

（２）太陽電池４および文字板５を、間隔をあけることなく積層して配置できるので、たとえば、太陽電池４および文字板５間に太陽電池押さえを設けて固定する構造を採用する場合に比べて、太陽電池付電子時計１を薄型化でき、日車２１の奥目感も緩和できる。 (2) Since the solar cell 4 and the dial plate 5 can be stacked and arranged without a gap, for example, as compared with a case where a solar cell presser is provided and fixed between the solar cell 4 and the dial plate 5. Thus, the electronic timepiece with solar cell 1 can be thinned, and the depth of the date wheel 21 can be reduced.

（３）文字板受けリング部材３のフック部４９を、太陽電池４の受光部４２よりも外周側に突出する突出部４６に形成している。このため、フック部４９をたとえばピンセットなどで保持し、太陽電池４および太陽電池案内板４５を文字板受けリング部材３に着脱するための作業を行った場合に、ピンセットなどで太陽電池４の受光部４２を傷つける可能性を低くできる。従って、太陽電池４の着脱作業時の作業性も向上できる。 (3) The hook portion 49 of the dial receiving ring member 3 is formed on the protruding portion 46 that protrudes more outward than the light receiving portion 42 of the solar cell 4. Therefore, when the hook portion 49 is held by, for example, tweezers and the work for attaching / detaching the solar cell 4 and the solar cell guide plate 45 to / from the dial receiving ring member 3 is performed, the light reception of the solar cell 4 by tweezers or the like is performed. The possibility of damaging the portion 42 can be reduced. Therefore, workability at the time of attaching / detaching the solar cell 4 can also be improved.

（４）太陽電池４の基材４１に被覆部４３を設け、被覆部４３で前記太陽電池案内板４５および文字板受けリング部材３の開口部３７を被覆しているので、太陽電池案内板４５や開口部３７が文字板５を介して時計表面側に透けて見えることを防止できる。
特に、ステンレス製の太陽電池案内板４５は、太陽電池４とは反射率が大きく異なり、太陽電池４で被覆されずに露出すると、外観上、太陽電池４との見栄えの相違が目立ってしまう。また、穴である開口部３７も、文字板５側に露出すると太陽電池４との相違が目立ってしまう。
一方、本実施形態では、太陽電池案内板４５や開口部３７を、太陽電池４の基材４１の被覆部４３で被覆しているので、これらの部位が文字板５から透けて見えることを防止でき、太陽電池付電子時計１の外観を向上できる。 (4) Since the covering portion 43 is provided on the base material 41 of the solar cell 4 and the covering portion 43 covers the solar cell guide plate 45 and the opening 37 of the dial receiving ring member 3, the solar cell guide plate 45. And the opening 37 can be prevented from being seen through the dial 5 via the dial face 5.
In particular, the solar cell guide plate 45 made of stainless steel has a significantly different reflectance from the solar cell 4, and when exposed without being covered with the solar cell 4, a difference in appearance from the solar cell 4 is conspicuous in appearance. Moreover, if the opening part 37 which is a hole is also exposed to the dial 5 side, the difference from the solar cell 4 will be conspicuous.
On the other hand, in this embodiment, since the solar cell guide plate 45 and the opening 37 are covered with the covering portion 43 of the base material 41 of the solar cell 4, these portions are prevented from being seen through the dial plate 5. It is possible to improve the appearance of the solar cell equipped electronic timepiece 1.

（５）太陽電池４の被覆部４３に係合溝４４を形成し、文字板受けリング部材３に太陽電池位置決め部３５を形成しているので、文字板受けリング部材３に対する太陽電池４の位置も正確に設定できる。 (5) Since the engagement groove 44 is formed in the covering portion 43 of the solar cell 4 and the solar cell positioning portion 35 is formed in the dial receiving ring member 3, the position of the solar cell 4 with respect to the dial receiving ring member 3 Can also be set accurately.

（６）太陽電池４の裏面に接着した太陽電池案内板４５は、ステンレス等の金属製であるため、太陽電池４を文字板受けリング部材３に取り付ける機能だけでなく、太陽電池４自体の強度を高めるためにも機能する。従って、太陽電池４の基材４１として合成樹脂製のフィルムなどを用いることもでき、太陽電池４の薄型化や低コスト化を実現できる。 (6) Since the solar cell guide plate 45 adhered to the back surface of the solar cell 4 is made of metal such as stainless steel, not only the function of attaching the solar cell 4 to the dial receiving ring member 3 but also the strength of the solar cell 4 itself. It also works to increase Therefore, a film made of a synthetic resin or the like can be used as the base material 41 of the solar cell 4, and the solar cell 4 can be reduced in thickness and cost.

（７）文字板受けリング部材３のフック部４９の形成位置を、ムーブメント２に形成されたサイドカット部２Ａ、２Ｂや文字板固定部３３、３４と異なる位置としているので、前記フック部４９をサイドカット部２Ａ、２Ｂよりも時計外周側にずらして配置したり、文字板固定部３３、３４をフック部４９の外周側にずらして配置する必要がない。
このため、ムーブメント２や太陽電池４、文字板５が配置される時計ケースの大型化を防ぐことができる。また、前記ムーブメント２のサイドカット部２Ａ、２Ｂを、時計文字板の３時および９時位置側に形成しているので、時計ケースにおける３時−９時方向の幅つまり時計の横幅の大型化を防止できる。 (7) Since the position of the hook portion 49 of the dial receiving ring member 3 is different from the side cut portions 2A, 2B and the dial fixing portions 33, 34 formed on the movement 2, the hook portion 49 is There is no need to displace the side cut portions 2A and 2B on the outer peripheral side of the watch, or to displace the dial fixing portions 33 and 34 on the outer peripheral side of the hook portion 49.
For this reason, the enlargement of the watch case in which the movement 2, the solar battery 4, and the dial 5 are arranged can be prevented. Further, since the side cut portions 2A and 2B of the movement 2 are formed on the side of the 3 o'clock and 9 o'clock positions of the timepiece dial, the width of the timepiece case in the 3 o'clock to 9 o'clock direction, that is, the lateral width of the timepiece is increased. Can be prevented.

（８）文字板受けリング部材３の表面において、前記開口部３７および太陽電池位置決め部３５が近接して設けられている。このため、太陽電池案内板４５の突出部４６に形成されるフック部４９と、太陽電池４の基材４１の被覆部４３に形成される係合溝４４とを近接して設けることができる。このため、太陽電池４の受光部４２の外周から突出して設けられる前記フック部４９および係合溝４４を近い位置に形成できるので、これらを被覆する基材４１の被覆部４３の面積を最小限に抑制できる。従って、太陽電池４の面積を最小化でき、太陽電池４のコストを低減できる。 (8) On the surface of the dial receiving ring member 3, the opening 37 and the solar cell positioning part 35 are provided close to each other. For this reason, the hook part 49 formed in the protrusion part 46 of the solar cell guide plate 45 and the engagement groove 44 formed in the covering part 43 of the base material 41 of the solar cell 4 can be provided close to each other. For this reason, since the hook part 49 and the engaging groove 44 provided so as to protrude from the outer periphery of the light receiving part 42 of the solar cell 4 can be formed at close positions, the area of the covering part 43 of the base material 41 covering these is minimized. Can be suppressed. Therefore, the area of the solar cell 4 can be minimized, and the cost of the solar cell 4 can be reduced.

（９）文字板受けリング部材３の表面側の色を、太陽電池４の色と同系色にしたので、太陽電池４および文字板受けリング部材３の色調を合わせることができる。このため、文字板受けリング部材３に対する色調の差によって、太陽電池４の外形が文字板５から透けて見えることを防止でき、時計の文字板５を見た際の外観を向上できる。 (9) Since the color of the surface side of the dial plate receiving ring member 3 is the same color as the color of the solar cell 4, the color tone of the solar cell 4 and the dial plate ring member 3 can be adjusted. For this reason, it is possible to prevent the outer shape of the solar cell 4 from being seen through the dial plate 5 due to the difference in color tone with respect to the dial plate ring member 3, and to improve the appearance when the dial plate 5 of the watch is viewed.

〔実施形態の変形〕
なお、本発明は前述の実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
たとえば、図７，８に示すフック係止部３８およびフック部４８で太陽電池４を文字板受けリング部材３Ａに取り付けてもよい。
すなわち、図７に示す文字板受けリング部材３Ａは、前記太陽電池支持面３１に開口する２つの開口部３６を備えている。開口部３６は、文字板受けリング部材３Ａの内周側にも開口する凹溝で構成されている。そして、開口部３６の周方向に沿った内周面には、フック係止部３８が形成されている。
フック係止部３８は、上面が傾斜面３８１とされた突起部で構成されている。フック係止部３８の傾斜面３８１は、太陽電池支持面３１から連続し、文字板受けリング部材３Ａの内周側（中心側）に向かうにしたがって、下方（裏蓋側）に傾斜する傾斜面とされている。 [Modification of Embodiment]
It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, you may attach the solar cell 4 to the dial receiving ring member 3A with the hook latching | locking part 38 and the hook part 48 which are shown to FIG.
That is, the dial receiving ring member 3 </ b> A shown in FIG. 7 includes two openings 36 that open to the solar cell support surface 31. The opening 36 is formed by a concave groove that also opens on the inner peripheral side of the dial receiving ring member 3A. A hook locking portion 38 is formed on the inner peripheral surface along the circumferential direction of the opening 36.
The hook engaging portion 38 is configured by a protruding portion whose upper surface is an inclined surface 381. The inclined surface 381 of the hook engaging portion 38 is continuous from the solar cell support surface 31 and is inclined downward (back cover side) toward the inner peripheral side (center side) of the dial receiving ring member 3A. It is said that.

一方、太陽電池案内板４５Ａの突出部４６は、図７，８に示すように、フック係止部３８に係合するフック部４８を備えている。フック部４８は、フック部４９と同様に、太陽電池案内板４５Ａから折曲されたＬ字状の板部で構成されている。また、フック部４８は、フック部４９と同様に、太陽電池４の基材４１の被覆部４３で被覆され、文字板５側から視認できないように構成されている。   On the other hand, the protruding portion 46 of the solar cell guide plate 45A includes a hook portion 48 that engages with the hook locking portion 38 as shown in FIGS. Similarly to the hook portion 49, the hook portion 48 is configured by an L-shaped plate portion bent from the solar cell guide plate 45 </ b> A. Similarly to the hook portion 49, the hook portion 48 is covered with the covering portion 43 of the base material 41 of the solar cell 4 so that it cannot be seen from the dial 5 side.

太陽電池案内板４５Ａが接着された太陽電池４を文字板受けリング部材３Ａに取り付けるには、フック部４８をフック係止部３８の傾斜面３８１に当接させ、そのまま太陽電池４を文字板受けリング部材３Ａ側に押し込む。すると、フック部４８は、傾斜面３８１に案内されて太陽電池案内板４５Ａの内側に湾曲する。そして、フック部４８が傾斜面３８１の下端を超えると、フック部４８は元の位置に戻る。このため、フック部４８は、フック係止部３８に係止される。
このようなフック係止部３８およびフック部４８を、文字板受けリング部材３Ａおよび太陽電池案内板４５Ａに形成した場合も、前記実施形態と同様の作用効果を奏することができる。 In order to attach the solar cell 4 to which the solar cell guide plate 45A is bonded to the dial receiving ring member 3A, the hook portion 48 is brought into contact with the inclined surface 381 of the hook engaging portion 38, and the solar cell 4 is received as it is. Push into the ring member 3A side. Then, the hook part 48 is guided by the inclined surface 381 and is curved inside the solar cell guide plate 45A. And if the hook part 48 exceeds the lower end of the inclined surface 381, the hook part 48 will return to the original position. For this reason, the hook portion 48 is locked to the hook locking portion 38.
Even when the hook engaging portion 38 and the hook portion 48 are formed on the dial receiving ring member 3A and the solar cell guide plate 45A, the same operational effects as those of the above embodiment can be obtained.

また、前記実施形態では、円環状の文字板受けリング部材３を用いていたが、図９に示すように、平面矩形枠状の文字板受けリング部材３Ｂを用いてもよい。このような文字板受けリング部材３Ｂを用いれば、文字板や時計ケースが角型のモデルを構成できる。なお、文字板受けリング部材３Ｂには、文字板受けリング部材３Ａと同様のフック係止部３８が形成されている。このため、太陽電池４には、フック部４８を有する太陽電池案内板４５Ａが接着されている。
この場合も、文字板受けリング部材３Ｂや太陽電池案内板４５Ａ以外の部品は前記第１実施形態の太陽電池付電子時計１と同様のものを利用できるので、コストを低減でき、前記第１実施形態と同様に、見切り径の制約が無いため、時計のモデルバリエーションを広げることができる。
また、ムーブメント２の３時および９時位置がサイドカット部２Ａ、２Ｂとされているので、角型の腕時計を構成する場合に、時計ケースの幅寸法を抑制でき、この点でもモデルバリエーションを広げることができる。 Moreover, in the said embodiment, although the annular | circular shaped dial receiving ring member 3 was used, as shown in FIG. 9, you may use the flat rectangular frame-shaped dial receiving ring member 3B. If such a dial receiving ring member 3B is used, a dial or a watch case can constitute a square model. The dial receiving ring member 3B is formed with a hook engaging portion 38 similar to the dial receiving ring member 3A. Therefore, a solar cell guide plate 45 </ b> A having a hook portion 48 is bonded to the solar cell 4.
Also in this case, since components other than the dial receiving ring member 3B and the solar cell guide plate 45A can be the same as those of the electronic timepiece with solar cell 1 of the first embodiment, the cost can be reduced and the first embodiment can be achieved. Like the form, there is no restriction on the parting diameter, so that the model variations of the watch can be expanded.
In addition, since the 3 o'clock and 9 o'clock positions of the movement 2 are the side cut portions 2A and 2B, the width of the watch case can be suppressed when configuring a square wristwatch, and this also widens the model variation. be able to.

前記実施形態では、文字板受けリング部材３でムーブメント２を保持し、その後に太陽電池４を文字板受けリング部材３に保持させたが、太陽電池４を先に文字板受けリング部材３に組み込み、これをムーブメント２にセットする組み立て順であってもよい。
また、本発明に用いることができるムーブメント２は、サイドカット部２Ａ、２Ｂを有するものに限定されない。
さらに、各フック部４８，４９および係合溝４４，４７、すなわち開口部３６，３７および太陽電池位置決め部３５は近接して配置されていなくてもよい。
また、前記実施形態では、太陽電池案内板４５に係合溝４７を形成していたが、係合溝４７を設けずに、フック部４８やフック部４９のみを設けてもよい。さらに、前記実施形態では、太陽電池案内板４５の中心を挟んで対向する２箇所にフック部４９を設けていたが、文字板受けリング部材３の周方向にそって３箇所以上にフック部４９やフック部４８を設けてもよい。 In the above embodiment, the movement 2 is held by the dial receiving ring member 3, and then the solar cell 4 is held by the dial receiving ring member 3. However, the solar cell 4 is first incorporated in the dial receiving ring member 3. The assembly order in which the movement 2 is set may be used.
The movement 2 that can be used in the present invention is not limited to the one having the side cut portions 2A and 2B.
