しかしながら、特許文献1に記載の時計では、回転板を大型化すると、コイルばねと回転板とが干渉してしまう。この干渉を防止するためには、平面視で回転板の外周縁よりも外側の位置にコイルばねを配置できるように回路基板を回転板よりも大きくする必要がある。
したがって、回転板のサイズが異なる複数種類の時計を設計する場合、回転板の大きさに合わせて回路基板のサイズを変更しなければならず、時計の製造コストが高くなる、という問題がある。
However, in the timepiece described in Patent Document 1, when the rotating plate is enlarged, the coil spring and the rotating plate interfere with each other. In order to prevent this interference, it is necessary to make the circuit board larger than the rotating plate so that the coil spring can be arranged at a position outside the outer peripheral edge of the rotating plate in plan view.
Therefore, when designing a plurality of types of timepieces having different sizes of the rotating plate, there is a problem in that the size of the circuit board must be changed in accordance with the size of the rotating plate, which increases the manufacturing cost of the timepiece.

Specifically, FIG. 3 is a cross-sectional view of the vicinity of the conductive member 6 as viewed from the side, and FIG. 4 is a plan view of the main plate 2, the date wheel 4 and the conductive member 6 as viewed from the front side.
The conducting member 6 is a member for conducting the circuit board 3 and the solar cell 5.
The conductive member 6 is made of a conductive material such as metal, and includes a first coil spring 61, a second coil spring 62, and a connecting portion 63, as shown in FIGS. The structure is formed integrally.

第1のコイルばね61、第2のコイルばね62および連結部63は、1本の同径の線材によって構成されている。第1のコイルばね61および第2のコイルばね62は、ばねの軸線が直線状の圧縮コイルばねで構成されている。また、第1のコイルばね61と第2のコイルばね62とは、同一のばね形状で構成されている。具体的に、第1のコイルばね61と第2のコイルばね62とは、コイル径、巻数およびコイルの高さ(軸線方向の長さ)等が全て同一の構造となっている。   The 1st coil spring 61, the 2nd coil spring 62, and the connection part 63 are comprised with one wire with the same diameter. The first coil spring 61 and the second coil spring 62 are composed of compression coil springs whose spring axes are linear. Moreover, the 1st coil spring 61 and the 2nd coil spring 62 are comprised by the same spring shape. Specifically, the first coil spring 61 and the second coil spring 62 all have the same structure in terms of coil diameter, number of turns, coil height (axial length), and the like.

連結部63は、導通部材6が日車4と干渉することを防止するためのものである。この連結部63は、第1のコイルばね61の他端側の端部61Bと、第2のコイルばね62の他端側の端部62Bとを互いに連結している。
この連結部63は、図4に示すように、第1のコイルばね61および第2のコイルばね62を、第1のコイルばね61および第2のコイルばね62の各コイルによる2つの円の共通外接線のうち、平面視で地板2の外周縁側に位置する共通外接線で連結する形状を有している。また、この連結部63は、図3に示すように、各コイルばね61,62の軸線に対して直交するように設けられている。

このように構成された導通部材6は、前述した地板2の取付部2Aに取り付けられる。
In addition, even if the conduction member 6 rotates so that the positions of the first coil spring 61 and the second coil spring 62 are switched, the shape of the same position before and after the rotation has the same structure. Specifically, the conducting member 6 is configured such that the spring shaft of the first coil spring 61 and the spring shaft of the second coil spring 62 are parallel to each other. The conducting member 6 includes a direction from the end portion 61A of the first coil spring 61 toward the end portion 61B, and an end portion 62B of the second coil spring 62 on the spring axis of the second coil spring 62. The directions toward are opposite to each other. In other words, the conducting member 6 is configured at a central position in the longitudinal direction of the connecting portion 63 and has a 180-degree rotationally symmetric shape around the center line orthogonal to the axis of the connecting portion 63 and the coil springs 61 and 62. Yes.
The conducting member 6 configured in this way is attached to the attaching portion 2A of the ground plate 2 described above.

[導通部材の取付部の構成]
以下、地板2の取付部2Aの構成について説明する。
取付部2Aは、地板2の表面および裏面に凹凸を設けることで形成されている。この取付部2Aは、図1に示すように、嵌込部21と、案内部22と、突起部23と、設置部24とを備えている。
[Configuration of mounting part of conductive member]
Hereinafter, the configuration of the mounting portion 2A of the main plate 2 will be described.
2A of attachment parts are formed by providing an unevenness | corrugation in the surface and the back surface of the ground plane 2. FIG. As shown in FIG. 1, the mounting portion 2 </ b> A includes a fitting portion 21, a guide portion 22, a protruding portion 23, and an installation portion 24.

図5は、嵌込部21および案内部22の構成を示す断面図である。
嵌込部21は、第1のコイルばね61を嵌め込む部分である。この嵌込部21は、地板2の裏面に凹状に形成されている。詳述すると、嵌込部21は、地板2の裏側が開口し、表側が閉塞している。なお、この嵌込部21の内壁の高さは、第1のコイルばね61のコイルの高さ(圧縮されていない状態の高さ)よりも小さく構成されている。この嵌込部21における地板2の外周縁側に位置する側面には、嵌込部21に第1のコイルばね61を嵌め込んで連結部63を通すための開口部21Aが設けられている。
FIG. 5 is a cross-sectional view showing the configuration of the fitting portion 21 and the guide portion 22.
The fitting portion 21 is a portion into which the first coil spring 61 is fitted. The fitting portion 21 is formed in a concave shape on the back surface of the main plate 2. If it explains in full detail, as for the insertion part 21, the back side of the baseplate 2 will open and the front side will be obstruct | occluded. In addition, the height of the inner wall of the fitting portion 21 is configured to be smaller than the height of the coil of the first coil spring 61 (the height in an uncompressed state). An opening portion 21 </ b> A for fitting the first coil spring 61 into the fitting portion 21 and passing the connecting portion 63 is provided on the side surface of the fitting portion 21 located on the outer peripheral edge side of the base plate 2.

案内部22は、開口部21Aを地板2の表面に通じさせる部分である。この案内部22は、嵌込部21における開口部21Aが設けられた地板2の外周縁側に設けられている。また、この案内部22は、傾斜面22Aを有している。
傾斜面22Aは、図5に示すように、導通部材6を地板2に取り付ける際に、第1のコイルばね61を嵌込部21の開口部21Aに案内するためのものである。なお、図5中の実線で示した導通部材6は、取り付け途中での第1のコイルばね61を示し、二点鎖線は、取り付け後の第1のコイルばね61を示している。
この傾斜面22Aは、表側から裏側に向かうにつれて開口部21Aまでの距離Lが小さくなるように傾斜している。この傾斜面22Aと地板2との最小開口寸法L1は、圧縮状態の第1のコイルばね61を挿通できる寸法とされている。
The guide 22 is a part that allows the opening 21 </ b> A to communicate with the surface of the main plate 2. The guide portion 22 is provided on the outer peripheral edge side of the base plate 2 in which the opening portion 21 </ b> A in the fitting portion 21 is provided. The guide portion 22 has an inclined surface 22A.
As shown in FIG. 5, the inclined surface 22 </ b> A is for guiding the first coil spring 61 to the opening 21 </ b> A of the fitting portion 21 when the conductive member 6 is attached to the base plate 2. In addition, the conduction member 6 shown by the solid line in FIG. 5 shows the first coil spring 61 during attachment, and the two-dot chain line shows the first coil spring 61 after attachment.
The inclined surface 22A is inclined so that the distance L to the opening 21A decreases from the front side to the back side. The minimum opening dimension L1 between the inclined surface 22A and the ground plane 2 is a dimension that allows the first coil spring 61 in a compressed state to be inserted.

突起部23は、導通部材6が地板2から外れることを防止するためのものである。この突起部23は、図1に示すように、嵌込部21および案内部22と、後述する設置部24との間における地板2の表面に設けられている。なお、この突起部23は、図4に示すように、取付部2Aへの導通部材6の取り付け後において、連結部63よりも地板2の外周縁側の位置に設けられている。具体的に、突起部23は、取り付け後の連結部63に沿うように、連結部63の直径と略同じ高さに形成されている。   The protrusion 23 is for preventing the conducting member 6 from being detached from the main plate 2. As shown in FIG. 1, the protruding portion 23 is provided on the surface of the ground plane 2 between the fitting portion 21 and the guide portion 22 and an installation portion 24 described later. As shown in FIG. 4, the protrusion 23 is provided at a position closer to the outer peripheral edge side of the base plate 2 than the connecting portion 63 after the conduction member 6 is attached to the attachment portion 2 </ b> A. Specifically, the projecting portion 23 is formed at substantially the same height as the diameter of the connecting portion 63 along the connecting portion 63 after attachment.

設置部24は、第2のコイルばね62を設置する部分である。この設置部24は、地板2の表面に凹状に形成されている。詳述すると、設置部24は、地板2の表側が開口し、裏側が閉塞している。なお、この設置部24の内壁の高さは、第2のコイルばね62のコイルの高さ(圧縮されていない状態の高さ)よりも小さく構成されている。また、設置部24の側面には、図1に示すように、導通部材6を取り付けた際に、連結部63が通る切欠24Aが形成されている。   The installation portion 24 is a portion where the second coil spring 62 is installed. The installation portion 24 is formed in a concave shape on the surface of the ground plane 2. More specifically, the installation part 24 is open on the front side of the main plate 2 and closed on the back side. In addition, the height of the inner wall of the installation portion 24 is configured to be smaller than the height of the coil of the second coil spring 62 (the height in an uncompressed state). Further, as shown in FIG. 1, a cutout 24 </ b> A through which the connecting portion 63 passes when the conductive member 6 is attached is formed on the side surface of the installation portion 24.

この切欠24Aは、幅寸法が第2のコイルばね62の直径よりも小さく、設置部24に設置した第2のコイルばね62が切欠24Aを通って設置部24から外れないように構成されている。また、切欠24Aは、第2のコイルばね62を設置部24に設置した状態の導通部材6を、第2のコイルばね62を中心として第1のコイルばね61側が案内部22から嵌込部21の範囲で回転可能な幅寸法に構成されている。
なお、取付部2Aに取り付けられた導通部材6は、第2のコイルばね62を中心に第1のコイルばね61が嵌込部21から案内部22側へ回転しようとすると、連結部63が突起部23に当接する。したがって、この場合、導通部材6は、その回転が規制され、嵌込部21から第1のコイルばね61が外れることが防止される。
The notch 24A is configured such that the width dimension is smaller than the diameter of the second coil spring 62, and the second coil spring 62 installed in the installation part 24 does not come off the installation part 24 through the notch 24A. . Further, the notch 24 </ b> A has the conductive member 6 in a state where the second coil spring 62 is installed in the installation portion 24, and the first coil spring 61 side from the guide portion 22 to the fitting portion 21 around the second coil spring 62. It is comprised in the width dimension which can be rotated in the range.
In addition, when the first coil spring 61 tries to rotate from the fitting portion 21 toward the guide portion 22 around the second coil spring 62, the connecting portion 63 protrudes from the conductive member 6 attached to the attachment portion 2A. It contacts the part 23. Therefore, in this case, the rotation of the conductive member 6 is restricted, and the first coil spring 61 is prevented from being detached from the fitting portion 21.

[太陽電池付時計の組み立て]
図6および図7は、太陽電池付時計1の組み立てを説明するための図である。
図6に示すように、先ず、地板2の取付部2Aに、導通部材6を取り付ける。この際、第1のコイルばね61よりも先に第2のコイルばね62を設置部24に設置する。すなわち、地板2の表側から第2のコイルばね62を、図1に示すように、端部62Bが設置部24に当接する向きで設置部24に設置される。
[Assembly timepiece with solar battery]
6 and 7 are diagrams for explaining the assembly of the solar cell timepiece 1.
As shown in FIG. 6, first, the conduction member 6 is attached to the attachment portion 2 </ b> A of the base plate 2. At this time, the second coil spring 62 is installed in the installation unit 24 before the first coil spring 61. That is, as shown in FIG. 1, the second coil spring 62 is installed on the installation unit 24 from the front side of the base plate 2 with the end 62 </ b> B coming into contact with the installation unit 24.

次に、第1のコイルばね61を、図5に示したように、案内部22の傾斜面22Aに沿って地板2の外側から内側に向けて押し込み、第1のコイルばね61を嵌込部21に嵌め込む。この際、連結部63が突起部23を乗り越えて、平面視で連結部63よりも地板2の外周端側の位置に突起部23が配置されるようにする。
これにより、導通部材6は、第1のコイルばね61の端部61Aが地板2の裏側を向き、第2のコイルばね62の端部62Aが表側を向くように取付部2Aに取り付けられる。なお、第1のコイルばね61は、圧縮されていない状態では、端部61Aが地板2の裏面から突出する。同様に、第2のコイルばね62は、圧縮されていない状態では、端部62Aが地板2の表面から突出する。
Next, as shown in FIG. 5, the first coil spring 61 is pushed inward from the outside of the main plate 2 along the inclined surface 22A of the guide portion 22, and the first coil spring 61 is inserted into the fitting portion. Fit into 21. At this time, the connecting portion 63 gets over the protruding portion 23 so that the protruding portion 23 is arranged at a position closer to the outer peripheral end of the base plate 2 than the connecting portion 63 in plan view.
Thereby, the conduction member 6 is attached to the attachment portion 2A so that the end portion 61A of the first coil spring 61 faces the back side of the base plate 2 and the end portion 62A of the second coil spring 62 faces the front side. Note that the first coil spring 61 protrudes from the back surface of the main plate 2 in the end portion 61 </ b> A in an uncompressed state. Similarly, in the state where the second coil spring 62 is not compressed, the end portion 62 </ b> A protrudes from the surface of the main plate 2.

地板2に導通部材6を取り付け後、図7に示すように、地板2の表側に日車4を取り付け、さらに、日車4の表側に太陽電池5を重ね、日車4と太陽電池5は断面的に干渉しないように取り付ける。また、地板2の裏側に回路基板3を取り付ける。
そして、各部材2〜6を太陽電池付時計1の外装ケースに収容することで、太陽電池付時計1を組み立てる。
After attaching the conducting member 6 to the main plate 2, as shown in FIG. 7, the date wheel 4 is attached to the front side of the main plate 2, and the solar cell 5 is stacked on the front side of the date indicator 4. Install so as not to interfere with the cross section. Further, the circuit board 3 is attached to the back side of the ground plane 2.
And the timepiece 1 with a solar cell is assembled by accommodating each member 2-6 in the exterior case of the timepiece 1 with a solar cell.

この組み立て後の導通部材6は、図3に示したように、第1のコイルばね61が平面視で回路基板3の端子部31と重なり、第2のコイルばね62が平面視で太陽電池5の電極部53と重なる位置に取り付けられる。また、導通部材6は、第1のコイルばね61が平面視で日車4と重なり、第2のコイルばね62が平面視で日車4の外周縁よりも外側(日車4と平面視で重ならない位置)の位置となるように取り付けられる。
なお、導通部材6は、第1のコイルばね61の端部61Aが回路基板3の端子部31に圧接され、第2のコイルばね62の端部62Aが太陽電池5の電極部53に圧接される。これにより、回路基板3と太陽電池5とが導通部材6を介して導通する。
As shown in FIG. 3, the assembled conductive member 6 has a first coil spring 61 overlapping the terminal portion 31 of the circuit board 3 in a plan view, and a second coil spring 62 in the plan view. It is attached to a position that overlaps with the electrode portion 53. In addition, the conductive member 6 includes a first coil spring 61 that overlaps the date indicator 4 in plan view, and a second coil spring 62 that is outside the outer periphery of the date indicator 4 in plan view (in the plan view with the date indicator 4). It is attached so that it will be in a position that does not overlap).
The conducting member 6 is configured such that the end 61A of the first coil spring 61 is in pressure contact with the terminal portion 31 of the circuit board 3, and the end 62A of the second coil spring 62 is in pressure contact with the electrode portion 53 of the solar cell 5. The Thereby, the circuit board 3 and the solar cell 5 are conducted through the conducting member 6.

このような本発明によれば、次のような作用効果を奏する。
回路基板3の端子部31に第1のコイルばね61の端部61Aが圧接され、太陽電池5の電極部53に第2のコイルばね62の端部62Aが圧接される。そして、導通部材6は、この第1のコイルばね61および第2のコイルばね62と、連結部63とを備えて一体に形成した構成であり、連結部63は、第1のコイルばね61および第2のコイルばね62の他端側を互いに連結する。このため、連結部63によって第1のコイルばね61と第2のコイルばね62とを平面的に異なる位置に配置することができる。したがって、回路基板3の端子部31が平面視で日車4と重なる位置にあり、太陽電池5の電極部53が平面視で日車4の外周縁よりも外側の位置にあっても、導通部材6と日車4とが干渉することなく、回路基板3と太陽電池5とを導通部材6によって導通できる。また、回路基板3と太陽電池5を導通するために、回路基板3の端子部31が平面視で日車4の外周縁よりも外側に位置するように、新たに回路基板3を設計する必要がないことから、太陽電池付時計1の製造コストが高くなることを防止できる。
According to such this invention, there exist the following effects.
The end portion 61A of the first coil spring 61 is pressed into contact with the terminal portion 31 of the circuit board 3, and the end portion 62A of the second coil spring 62 is pressed into contact with the electrode portion 53 of the solar cell 5. The conducting member 6 includes the first coil spring 61 and the second coil spring 62, and a connecting portion 63, and is integrally formed. The connecting portion 63 includes the first coil spring 61 and the connecting portion 63. The other end sides of the second coil springs 62 are connected to each other. For this reason, the 1st coil spring 61 and the 2nd coil spring 62 can be arrange | positioned in a plane different position by the connection part 63. FIG. Therefore, even if the terminal part 31 of the circuit board 3 is in a position overlapping the date indicator 4 in plan view, and the electrode part 53 of the solar cell 5 is in a position outside the outer peripheral edge of the date indicator 4 in plan view, it is conductive. The circuit board 3 and the solar cell 5 can be conducted by the conducting member 6 without the member 6 and the date wheel 4 interfering with each other. Further, in order to make the circuit board 3 and the solar cell 5 conductive, it is necessary to newly design the circuit board 3 so that the terminal portion 31 of the circuit board 3 is located outside the outer peripheral edge of the date wheel 4 in plan view. Therefore, the manufacturing cost of the solar cell timepiece 1 can be prevented from increasing.

導通部材6が、第1のコイルばね61の端部61Aから端部61Bに向かう方向と、第2のコイルばね62の端部62Aから端部62Bに向かう方向とを互いに反対向きに構成し、各コイルばね61,62の各コイルの軸方向の長さを同じとしている。このため、第1のコイルばね61の端部61Aおよび第2のコイルばね62の端部62Aのいずれか一方を太陽電池5の電極部53に圧接させ、他方を回路基板3の端子部31に圧接させることで、回路基板3と太陽電池5とを導通させることができる。これにより、地板2に導通部材6を取り付ける際に、各コイルばね61,62の向きを気にする必要がなくなり、太陽電池付時計1の組立性を向上できる。また、第1のコイルばね61と第2のコイルばね62とは、コイル径、巻数およびコイルの高さ等が全て同一の構造であるため、各コイルばね61,62により生じる応力も導通部材6の取り付け向きに関わらず同一とすることができる。   The conducting member 6 is configured so that the direction from the end 61A of the first coil spring 61 toward the end 61B and the direction from the end 62A of the second coil spring 62 toward the end 62B are opposite to each other. The lengths in the axial direction of the coils of the coil springs 61 and 62 are the same. For this reason, one of the end portion 61A of the first coil spring 61 and the end portion 62A of the second coil spring 62 is brought into pressure contact with the electrode portion 53 of the solar cell 5, and the other is brought into contact with the terminal portion 31 of the circuit board 3. The circuit board 3 and the solar cell 5 can be electrically connected by press-contacting. Thereby, when attaching the conduction | electrical_connection member 6 to the ground plane 2, it becomes unnecessary to care about the direction of each coil spring 61 and 62, and the assembly property of the solar cell timepiece 1 can be improved. Further, since the first coil spring 61 and the second coil spring 62 have the same structure in coil diameter, number of turns, coil height, and the like, the stress generated by each of the coil springs 61 and 62 is also the conductive member 6. It can be the same regardless of the mounting direction.

取付部2Aに導通部材6を取り付ける際、第1のコイルばね61は、地板2の表側から案内部22および開口部21Aを介して嵌込部21に嵌め込まれる。また、第2のコイルばね62は、地板2の表側から設置部24に設置される。なお、連結部63は、嵌込部21の開口部21Aと、設置部24の切欠24Aを通して配置される。そして、第1のコイルばね61を嵌込部21に嵌め込む際に、第1のコイルばね61は、案内部22が有する傾斜面22Aによって嵌込部21まで案内される。このため、第1のコイルばね61を嵌込部21に簡単に嵌め込むことができ、導通部材6を地板2に容易に取り付けることができる。
また、回路基板3は、地板2の裏側に取り付けられ、導通部材6は、地板2の表側から取付部2Aに取り付けられる。このため、回路基板3を地板2に取り付けた後であっても、導通部材6を容易に組み込むことができる。
When attaching the conducting member 6 to the attachment portion 2A, the first coil spring 61 is fitted into the fitting portion 21 from the front side of the main plate 2 via the guide portion 22 and the opening portion 21A. The second coil spring 62 is installed on the installation unit 24 from the front side of the main plate 2. The connecting portion 63 is disposed through the opening 21A of the fitting portion 21 and the notch 24A of the installation portion 24. Then, when the first coil spring 61 is fitted into the fitting part 21, the first coil spring 61 is guided to the fitting part 21 by the inclined surface 22 </ b> A of the guide part 22. For this reason, the first coil spring 61 can be easily fitted into the fitting portion 21, and the conducting member 6 can be easily attached to the ground plane 2.
The circuit board 3 is attached to the back side of the base plate 2, and the conductive member 6 is attached to the attachment portion 2 </ b> A from the front side of the base plate 2. For this reason, even after the circuit board 3 is attached to the ground plane 2, the conductive member 6 can be easily incorporated.

嵌込部21における地板2の外周縁側に開口部21Aが設けられており、嵌込部21には、平面視で地板2の外周縁側から中心側に向かって第1のコイルばね61が嵌め込まれる。このことから、第1のコイルばね61は、落下等の衝撃によって地板2の外周縁側に向かって外れる可能性がある。しかしながら、地板2が連結部63よりも外周縁側の位置に突起部23を備えているので、嵌込部21から第1のコイルばね61が外れそうになった場合であっても突起部23によって連結部63が押さえられるので、嵌込部21から第1のコイルばね61が外れることを防止でき、結果として導通部材6が地板2から外れることを防止できる。   An opening 21A is provided on the outer peripheral edge side of the base plate 2 in the insertion portion 21, and the first coil spring 61 is inserted into the insertion portion 21 from the outer peripheral edge side to the center side of the base plate 2 in plan view. . For this reason, the first coil spring 61 may come off toward the outer peripheral edge of the main plate 2 due to an impact such as dropping. However, since the base plate 2 is provided with the protruding portion 23 at a position on the outer peripheral edge side with respect to the connecting portion 63, even when the first coil spring 61 is likely to be detached from the fitting portion 21, Since the connecting portion 63 is pressed, it is possible to prevent the first coil spring 61 from being detached from the fitting portion 21, and as a result, it is possible to prevent the conducting member 6 from being detached from the ground plane 2.

連結部63が地板2の外周縁側に位置する共通外接線で連結する形状を有しているので、連結部63を地板2の中心側に位置する共通外接線で連結する形状とした場合と比較して、導通部材6の平面視での日車4と重なる部分を少なくできる。このことから、落下等の衝撃によって導通部材6が地板2から外れたような場合であっても、導通部材6が日車4と干渉することを防止できる。   Since the connecting portion 63 has a shape that is connected by a common outer tangent line that is located on the outer peripheral edge side of the ground plane 2, it is compared with a case where the connecting portion 63 is connected by a common outer tangent line that is located on the center side of the ground plane 2. And the part which overlaps with the date wheel 4 in planar view of the conduction | electrical_connection member 6 can be decreased. Therefore, even when the conducting member 6 is detached from the main plate 2 due to an impact such as dropping, the conducting member 6 can be prevented from interfering with the date wheel 4.

第1のコイルばね61の端部61Bは、嵌込部21に当接し、第2のコイルばね62の端部62Bは、設置部24に当接するため、回路基板3と太陽電池5とを導通部材6を介して圧接させるのに十分な応力を確保することができる。
太陽電池5は、平面視で日車4と重なる位置から、日車4の外周縁よりも外側の位置に跨って形成された電極部53を備えている。このため、太陽電池5は、他の小型の日車を採用し、ばね軸が直線状の1本のコイルばねで回路基板と太陽電池とを導通する太陽電池付時計の太陽電池としても採用できる。
Since the end portion 61B of the first coil spring 61 abuts on the fitting portion 21 and the end portion 62B of the second coil spring 62 abuts on the installation portion 24, the circuit board 3 and the solar cell 5 are electrically connected. Sufficient stress can be ensured for press-contact through the member 6.
The solar cell 5 includes an electrode portion 53 that is formed to extend from a position overlapping the date wheel 4 in plan view to a position outside the outer peripheral edge of the date wheel 4. For this reason, the solar cell 5 can also be used as a solar cell of a solar cell timepiece that employs another small date wheel and that has a linear spring shaft that connects the circuit board and the solar cell. .
