The electronic timepiece 1 and the electronic timepiece 101 have common parts and non-common parts. The combination of the electronic timepiece 1 and the electronic timepiece 101 is called an electronic timepiece set.
[0026] <2. First Electronic Watch>
[0027] The electronic timepiece 1 comprises a housing, Figure 1 The internal structure (module) of the electronic timepiece 1 shown is housed in a housing. The housing is worn on the user's arm through an armband or an arm band. The housing comprises a metal or resin frame-shaped housing body, a resin or glass transparent windshield, and a metal or resin back cover. The windshield is fixed to the surface (front) of the housing body in a manner covering the hollow portion of the housing body, and the back cover is fixed to the back of the housing body in a manner covering the hollow portion of the housing body.
[0028] like Figure 1 As shown, the electronic timepiece 1 has a circuit board 10, a main board 20, a spacer 40, a solar panel 50, a date wheel 60, a date wheel pressure plate 70 and a dial 80 as an internal structure (module) from the back to the front.

Figure 6 Observed in the direction of the arrow Figure 2 The cross-sectional view shown is a cross-sectional view along the cutting line VI.
[0029] (1) Circuit board
[0030] The circuit board 10 has electrical components such as an antenna 11, a transceiver 12, a light emitting element, a terminal, an IC (Integrated Circuit) chip, a secondary battery, and a terminal mounted on the circuit board 10. The antenna 11 is a wireless communication component that receives a standard radio wave for correcting the time. The transceiver 12 is a wireless communication component composed of an antenna, a transmitter, a receiver, and a controller. The communication standard of the transceiver 12 adopts Bluetooth (registered trademark) Low Energy (Bluetooth Low Energy) abbreviated as BLE, Wi-Fi (wireless communication, registered trademark) or ZigBee (ZigBee protocol, registered trademark) and the like. Since the transceiver 12 and the antenna 11 are arranged separately from each other, interference between the transceiver 12 and the antenna 11 is prevented. When the positions of the antenna 11 and the transceiver 12 are expressed by the clock position, the antenna 11 is arranged at the 12 o'clock position, and the transceiver 12 is arranged at the 5 o'clock and 6 o'clock positions.
[0031] In addition, an antenna for wireless communication based on a communication standard such as BLE, Wi-Fi, or ZigBee may be mounted on the circuit board 10 instead of the transceiver 12. The mounting position of the antenna is the same as that of the transceiver 12.
[0032] (2) Motherboard
[0033] The main board 20 overlaps the surface of the circuit board 10. The shape of the main board 20 is based on a circular plate shape around the center axis passing through the center of the main board 20. Hereinafter, the direction parallel to the center axis passing through the center of the main board 20 is referred to as the axial direction, the direction along the circle around the center axis is referred to as the circumferential direction, and the direction along the diameter perpendicular to the center axis is referred to as the radial direction. The direction from the surface to the back of the main board 20 and the opposite direction are parallel to the axial direction. The thickness direction of the main board 20 is parallel to the axial direction.
[0034] In order to install, mount, stick, fix, support, hold, or arrange the components such as the plurality of motors 21, the plurality of gear train mechanisms 23, the crown 25, the antenna 11, the transceiver 12, the solar panel 50, and the spacer 40 on the main board 20 so that the above components can be well accommodated, the main board 20 has pins, protrusions, ribs, recesses, holes, cutouts, grooves, and internal threads. The motor 22 among the plurality of motors 21 is connected to the gear train mechanism 24 among the plurality of gear train mechanisms 23, and the gear train mechanism 24 is connected to the date wheel 60, which is rotationally driven by the motor 22 and the gear train mechanism 24. The other motors 21 and the other gear train mechanisms 23 rotationally drive the hands such as the second hand, minute hand, hour hand, or function hand.
[0035] In order to arrange the solar cell panel 50 and the spacer 40 on the surface of the main board 20 , the surface of the main board 20 is formed as follows.
[0036] The main board 20 has a first protrusion 31 on the outer periphery of the surface of the main board 20. The first protrusion 31 is formed along the outer periphery of the surface of the main board 20. The first protrusion 31 is interrupted at a plurality of locations on the outer periphery of the surface of the main board 20.
[0037] The main plate 20 has a plurality of second protrusions 32 on the surface of the main plate 20. The second protrusions 32 are formed in a concentric arc shape on the radially inner side of the first protrusions 31 so as to extend in the circumferential direction.
[0038] The main board 20 has a first configuration surface 33 on the surface of the main board 20. The first configuration surface 33 faces the windshield side. The first configuration surface 33 expands in the circumferential direction between the first convex portion 31 and the second convex portion 32. A portion of the first configuration surface 33 expands radially inward from between the second convex portions 32 and is referred to as an expansion portion 34a, 34b. In the present embodiment, the number of the expansion portions 34a, 34b is two, but it may be three or more, or it may be one. One expansion portion 34a and the other expansion portion 34b are arranged substantially symmetrically with respect to the center of the main board 20. Specifically, when the range where the expansion portions 34a, 34b are formed is represented by the clock position, one expansion portion 34a is formed in the range from the 1 o'clock position to the 2 o'clock position, and the other expansion portion 34b is formed at the 8 o'clock position. The height of the first configuration surface 33 is lower than the height of the top of the first convex portion 31. Therefore, the first convex portion 31 protrudes from the first configuration surface 33, and there is a height difference between the first configuration surface 33 and the top of the first convex portion 31. Likewise, the height of the first arrangement surface 33 is lower than the height of the top of the second convex portion 32. Here, the height refers to the position in the axial direction.
[0039] The main board 20 has a second configuration surface 35 at the center of the surface of the main board 20. The second configuration surface 35 faces the windshield side in the same manner as the first configuration surface 33. Therefore, the second configuration surface 35 faces the same direction as the direction faced by the first configuration surface 33. The second configuration surface 35 extends radially inwardly of the first configuration surface 33. The height of the second configuration surface 35 is higher than the height of the first configuration surface 33, and there is a height difference between the second configuration surface 35 and the first configuration surface 33. The second protrusion 32 extends circumferentially at the boundary between the first configuration surface 33 and the second configuration surface 35. The height of the second configuration surface 35 is lower than the height of the second protrusion 32. Therefore, the second protrusion 32 protrudes from the second configuration surface 35, and there is a height difference between the second configuration surface 35 and the top of the second protrusion 32.
[0040] The main board 20 has a plurality of first marks 36 formed on the first configuration surface 33. The first marks 36 indicate the bonding position of the double-sided adhesive tape 59 for fixing the solar cell panel 50 to the main board 20. In the present embodiment, the number of the first marks 36 is two, but it may be three or more, or it may be one. The position of the first mark 36 in the circumferential direction is between the expansion parts 34a and 34b, and the first mark 36 and the expansion parts 34a and 34b are alternately arranged in the circumferential direction. The first mark 36 is a recessed portion recessed from the first configuration surface 33. The first mark 36 is provided in an arc shape on the first configuration surface 33 in a manner extending in the circumferential direction. When the range where the first mark 36 is formed is represented by the clock position, the first first mark 36 is formed in the range from the 5 o'clock position to the 7 o'clock position. The second first mark 36 is formed in the range from the 9 o'clock position to the 11 o'clock position. In this way, the plurality of first marks 36 are arranged at substantially opposite positions on the surface of the main board 120, so that the solar cell panel is fixed in a manner that does not float. Since the first mark 36 is a concave portion, the height of the bottom of the concave portion is lower than the height of the first arrangement surface 33 , and there is a height difference between the bottom of the concave portion and the first arrangement surface 33 .
[0041] The main board 20 has a plurality of L-shaped second marks 37 formed on the first configuration surface 33. In the present embodiment, the number of the second marks 37 is three, but it may be four or more, or two or less. When the positions of the second marks 37 are represented by the clock positions, the first second mark 37 is arranged at the 2 o'clock position, the second second mark 37 is arranged at the 7 o'clock position, and the third second mark 37 is arranged at the 9 o'clock position. The above-mentioned second marks 37, the antenna 11, and the transceiver 12 are arranged in the circumferential direction. The second mark 37 arranged at the 2 o'clock position is arranged between the antenna 11 and the transceiver 12 in the circumferential direction. The second marks 37 arranged at the 7 o'clock position and the 9 o'clock position are arranged between the antenna 11 and the transceiver 12 in the circumferential direction. The second mark 37 arranged at the 2 o'clock position is arranged at a position substantially opposite to the second marks 37 arranged at the 7 o'clock position and the 9 o'clock position relative to the center of the main board 20. The second mark 37 is a recessed portion recessed from the first configuration surface 33. The height of the bottom of the recess is lower than the height of the first configuration surface 33, and there is a height difference between the bottom of the recess and the first configuration surface 33. The depth of the second mark 37 is not equal to the depth of the first mark 36. That is, the depth of the second mark 37 is deeper or shallower than the depth of the first mark 36. In addition, the depth of the second mark 37 may be equal to the depth of the first mark 36. The depth of the first mark 36 refers to the distance from the first configuration surface 33 to the bottom of the first mark 36. The depth of the second mark 37 refers to the distance from the first configuration surface 33 to the bottom of the second mark 37.
[0042] The second mark 37 may not be a recessed portion, and may be, for example, a printed ink cured film.
[0043] The positions and shapes of the above-mentioned first configuration surface 33, first protrusion 31, second protrusion 32, first configuration surface 33, second configuration surface 35, first mark 36 and second mark 37 are designed so as to facilitate the storage of the solar cell panel 50 and the spacer 40 so that the solar cell panel 50 and the spacer 40 can be well arranged on the surface of the main board 20.
[0044] (3) Double-sided adhesive tape
[0045] The double-sided adhesive tape 59 is a kind of pasting member such as an adhesive or a bonding agent. The double-sided adhesive tape 59 is also referred to as a double-sided adhesive tape. In addition, in the present embodiment, the double-sided adhesive tape is used as an adhesive, but it is not limited to a tape-shaped adhesive or a liquid or semi-cured adhesive or bonding material can also be used. The bottom of the concave first mark 36 is the first bonding surface to which the double-sided adhesive tape 59 is bonded, and the double-sided adhesive tape 59 is bonded to the bottom of the first mark 36. The double-sided adhesive tape 59 is arranged in an arc shape between the first convex portion 31 and the second convex portion 32 in a manner extending in the circumferential direction. The thickness of the double-sided adhesive tape 59 is equal to the depth of the first mark 36, or slightly larger than the depth. The depth of the first mark 36 refers to the distance from the first configuration surface 33 to the bottom of the first mark 36. The thickness of the double-sided adhesive tape 59 is set so that the height of the surface of the solar cell panel 50 fixed by the double-sided adhesive tape 59 is equal to the height of the surface of the spacer 40.
[0046] (4) Framework
[0047] The frame 45 is provided in an annular shape and is attached to the outer periphery of the main board 20 .
[0048] (5) Spacer
[0049] The spacer 40 is provided in a relatively thin sheet shape. The spacer 40 overlaps the center of the surface of the main board 20. Specifically, the spacer 40 is placed on the second configuration surface 35 of the main board 20. The surface of the spacer 40 is the surface on which the date wheel pressing plate 70 described below is placed. The spacer 40 may also be fixed to the main board 20 by an adhesive, an adhesive tape or a screw. The spacer 40 may also have a hole formed on the surface of the main board 20 into which a protrusion is embedded.
[0050] (6) Solar panels
[0051] The solar panel 50 is provided in a ring-shaped and relatively thin sheet. The solar panel 50 is placed on the first arrangement surface 33 of the main board 20 around the spacer 40. The solar panel 50 is adhered to the double-sided adhesive tape 59 and fixed to the surface of the main board 20 by the double-sided adhesive tape 59. Since the double-sided adhesive tape 59 is adhered to the bottom of the first mark 36 provided in a concave shape, the thickness of the double-sided adhesive tape 59 does not become a major factor in the bending deformation of the solar panel 50. The height of the surface of the solar panel 50 is consistent with the height of the surface of the spacer 40, and the above surfaces are coplanar.
[0052] The solar panel 50 has one or more photovoltaic elements that generate electromotive force by receiving light. The solar panel 50 is electrically connected to the circuit board 10 via a connector or the like, and the electromotive force of the solar panel 50 is supplied to the circuit board 10 or charges the secondary battery.
[0053] The solar panel 50 has a plurality of sheet-like extensions 51a and 51b extending radially inward from its inner circumference. In the present embodiment, the number of the extensions 51a and 51b is two, but it may be three or more, or it may be one. One extension 51a and the other extension 51b are arranged approximately symmetrically with respect to the center of the solar panel 50 and the main board 20. Specifically, when the positions of the extensions 51a and 51b are expressed by the clock position, one extension 51a is arranged and formed at the 1.5 o'clock position, and the other extension 51b is arranged at the 8 o'clock position. One extension 51a is placed on one expansion portion 34a of the first arrangement surface 33, and the other extension 51b is placed on the other expansion portion 34b. One extension 51a is arranged between the two first marks 36 in the circumferential direction, and is arranged between the two double-sided adhesive tapes 59 in the circumferential direction. The other extension 51b is arranged between the two first marks 36 in the circumferential direction, and is arranged between the two double-sided adhesive tapes 59 in the circumferential direction. One first mark 36 and the double-sided adhesive tape 59 bonded thereto are disposed circumferentially between the extension 51a and the extension 51b. Another first mark 36 and the double-sided adhesive tape 59 bonded thereto are disposed circumferentially between the extension 51a and the extension 51b.
[0054] The surfaces of the extensions 51a and 51b are surfaces on which the date wheel pressing plate 70 described below is placed. Terminals may be formed on the back surfaces of the extensions 51a and 51b. The terminals are electrically connected to the terminal pads of the circuit board 10 via conductors.
[0055] Since the second mark 37 is a recessed portion or an ink cured film, the second mark 37 does not become a factor of the bending deformation of the solar cell panel 50 .
[0056] In addition, if Figure 7As shown, the solar cell panel 50 may be provided in an arc shape with a cutout in a ring shape such as a C-shape or a semi-ring shape. In this case, an arc-shaped sheet having a color substantially the same as that of the solar cell panel 50 may be arranged in the cutout portion, and the arc-shaped solar cell panel 50 and the arc-shaped sheet may be combined to form an annular shape. Furthermore, in order to make the boundary between the arc-shaped solar cell panel 50 and the arc-shaped sheet inconspicuous, an annular light diffusion sheet may be overlapped on the surface of the arc-shaped solar cell panel 50 and the arc-shaped sheet.
[0057] (7) Date wheel
[0058] The date wheel 60 is disposed on the solar panel 50 in a state of floating from the solar panel 50. The date wheel 60 floats from the solar panel 50 because it is supported by the second convex portion 32. Therefore, the date wheel 60 does not receive resistance to the rotation of the date wheel 60 from the solar panel 50.
[0059] The date wheel 60 is made of a metal material such as stainless steel or titanium alloy. The date wheel 60 is a component that is processed by cutting such as mechanical cutting, stamping, etching, laser beam irradiation cutting, sandblasting or water jetting. The metallic luster of the date wheel 60 gives the date wheel 60 a sense of heaviness and luxury. The cutting process gives the date wheel 60 a sense of three-dimensionality and luxury.
[0060] The date wheel 60 includes an inner wheel 61, an outer wheel 62, a plurality of spokes 63, a plurality of openings 64, a plurality of text portions 65, and an inner gear 66. The inner wheel 61 is arranged inwardly separated from the outer wheel 62, and the inner wheel 61 and the outer wheel 62 are concentric. A plurality of spokes 63 are arranged at intervals in the circumferential direction between the inner wheel 61 and the outer wheel 62. The spokes 63 extend radially and are mounted on the inner wheel 61 and the outer wheel 62. The openings 64 are formed between adjacent spokes 63. The openings 64 penetrate from the surface of the date wheel 60 to the back. The openings 64 allow sunlight to pass through the solar panel 50. The text portions 65 are arranged in each opening 64. The text portions 65 are connected to the inner wheel 61, the outer wheel 62, or the spokes 63 through a thinner connecting rod. The inner gear 66 is formed on the inner circumference of the inner wheel 61. The inner gear 66 meshes with the output gear of the wheel train mechanism 23.
[0061] (8) Date wheel pressure plate
[0062] The date wheel pressing plate 70 overlaps with the spacer 40. The date wheel pressing plate 70 is provided in a disc shape. The outer periphery of the date wheel pressing plate 70 covers the inner gear 66 of the date wheel 60 from the windshield side. The outer periphery of the date wheel pressing plate 70 is separated from the inner gear 66 or is in soft contact with the inner gear 66. Soft contact means that the outer periphery of the date wheel pressing plate 70 is in contact with the inner gear 66 to such an extent that the outer periphery of the date wheel pressing plate 70 hardly applies resistance to the rotation of the date wheel 60.
[0063] The date wheel pressing plate 70 extends from the edge of the spacer 40 and the second configuration surface 35 toward the expansion parts 34a and 34b. The extended portion floats from the expansion parts 34a and 34b. The extended portion covers the extension parts 51a and 51b of the solar panel 50 from the windshield side and presses the extension parts 51a and 51b. As described above, since the height of the surface of the solar panel 50 is consistent with the height of the surface of the spacer 40, even if the date wheel pressing plate 70 overlaps with the spacer 40 and the extension parts 51a and 51b of the solar panel 50, the date wheel pressing plate 70 will not shake.
[0064] (9) Dial
[0065] The dial 80 overlaps with the date wheel pressure plate 70 and the date wheel 60. The dial 80 is supported by the date wheel pressure plate 70, whereby the dial 80 moves away from the date wheel 60 toward the windshield side. The dial 80 is made of a metal material or a resin material. The dial 80 is opaque. The dial 80 has a plurality of openings 64 arranged circumferentially at a position radially outward of the outer periphery of the date wheel pressure plate 70. The openings 64 pass from the surface of the dial 80 to the back. The openings 64 allow sunlight to pass toward one side of the date wheel 60 and the solar panel 50. The openings 64 are formed on the dial 80 so that the dial 80 can be seen in three dimensions. In addition, the dial 80 may also be transparent. In this case, the openings 64 may not be formed on the dial 80.
[0066] <3. Second electronic clock>
[0067] Like the electronic timepiece 1, the electronic timepiece 101 has a housing composed of a housing body, a windshield, and a back cover. Figure 7 The internal structure (module) of the electronic timepiece 101 shown is housed in a housing. Figure 7 to Figure 10 , the internal structure (module) inside the casing of the electronic timepiece 101 is described in detail. Figure 8 and Fig. 9 is a top view of the interior of the housing. Figure 8 and Fig. 9 This is a plan view of the electronic timepiece 101 as viewed from the windshield toward the rear cover. Figure 8 In the figure, the date wheel 160, the date wheel pressure plate 170, the solar panel 150 and the dial 180 are omitted. Fig. 9 In the figure, the antimagnetic plate 190, the date wheel 160, the date wheel pressure plate 170, the solar panel 150 and the dial 180 are omitted. Fig.10 Observed in the direction of the arrow Fig. 9 The cross-sectional view is shown along the section line XX. The housing of the electronic timepiece 101 may be of the same design as that of the housing of the electronic timepiece 1 or of a different design.
[0068] The electronic timepiece 101 includes a circuit board 110, a main board 120, a magnetic-resistant plate 190, a date wheel 160, a date wheel pressure plate 170, a solar panel 150 and a dial 180 as internal structures (modules) from the back to the front. The electronic timepiece 101 also has a frame 145 and a plurality of double-sided adhesive tapes 199.
[0069] (1) Circuit boards, motherboards, and frames
[0070] The circuit board 110 of the electronic timepiece 101 is the same as the circuit board 10 of the electronic timepiece 1. The main board 120 of the electronic timepiece 101 is the same as the main board 20 of the electronic timepiece 1. The frame 145 of the electronic timepiece 101 is the same as the frame 45 of the electronic timepiece 1. Just as the circuit board 10, the main board 20 and the frame 45 are assembled into one body in the electronic timepiece 1, the circuit board 110, the main board 120 and the frame 145 are also assembled into one body in the electronic timepiece 101. As in the case of the electronic timepiece 1, components such as a plurality of motors 121, a plurality of gear train mechanisms 123 and a crown 125 are mounted, carried, pasted, fixed, supported, held, or arranged on the main board 120.
[0071] (2)Magnetic resistant plate
[0072] The anti-magnetic plate 190 is provided in a relatively thin sheet shape. The planar shape of the anti-magnetic plate 190 is different from the planar shape of the solar cell panel 50 of the electronic timepiece 1. The thickness of the anti-magnetic plate 190 is not equal to the thickness of the solar cell panel 50 of the electronic timepiece 1. Specifically, the anti-magnetic plate 190 is thinner than the solar cell panel 50 of the electronic timepiece 1.
[0073] The magnetic-resistant plate 190 is made of a magnetic-collecting material such as cold-rolled steel or Permalloy. The magnetic-resistant plate 190 overlaps the center of the surface of the main board 120. Specifically, the magnetic-resistant plate 190 is placed across the first configuration surface and the second configuration surface 135 of the main board 120. The magnetic-resistant plate 190 has an area larger than the area of the spacer 40 of the electronic timepiece 1. The magnetic-resistant plate 190 extends from the edge of the second configuration surface 135 to the first configuration surface 133. Since the height of the second configuration surface 135 is higher than the height of the first configuration surface 133, the magnetic-resistant plate 190 floats from the first configuration surface 133.
[0074] The magnetic-resistant plate 190 covers the motor 121. The magnetic-resistant plate 190 magnetically shields the motor 121. The magnetic-resistant plate 190 is in a horizontally long (roughly elliptical) shape so as not to cover the antenna 111 and the transceiver 112, which are wireless communication components, and is arranged offset from the antenna 111 and the transceiver 112 in the plane direction. Therefore, the magnetic-resistant plate 190 does not magnetically shield the antenna 111 and the transceiver 112. Here, the plane direction refers to the direction along the plane perpendicular to the axial direction.
[0075] The main board 120 is the same as the main board 20, so the first arrangement surface 33, the first convex portion 131, the second convex portion 132, the first arrangement surface 133, the expansion portions 134a, 134b, the second arrangement surface 135, the first mark 136 and the second mark 137 are formed on the surface of the main board 120. In order to arrange the magnetic-resistant plate 190 on the surface of the main board 120 so that the magnetic-resistant plate 190 and the like can be well accommodated, the positions and shapes of the first convex portion 131, the second convex portion 132, the first arrangement surface 133, the second arrangement surface 135, the first mark 136 and the second mark 137 are designed. When the positions of the second marks 137 are expressed by the clock positions, the first second mark 137 is arranged at the 2 o'clock position, the second second mark 137 is arranged at the 7 o'clock position, and the third second mark 137 is arranged at the 9 o'clock position. The above-mentioned second marks 137, the antenna 111 and the transceiver 112 are arranged in the circumferential direction. The second mark 137 disposed at the 2 o'clock position is disposed between the antenna 111 and the transceiver 112 in the circumferential direction and is separated from the antenna 111 and the transceiver 112. The second marks 137 disposed at the 7 o'clock position and the 9 o'clock position are disposed between the antenna 111 and the transceiver 112 in the circumferential direction and are separated from the antenna 111 and the transceiver 112. The second mark 137 disposed at the 2 o'clock position is disposed at a position substantially opposite to the second marks 137 disposed at the 7 o'clock position and the 9 o'clock position relative to the center of the main board 20. In this way, the plurality of second marks 137 are disposed at substantially opposite positions on the surface of the main board 120, so that when the magnetic-resistant plate 190 is bonded to the main board 120 using the double-sided adhesive tape 199 whose bonding position is specified by the second marks 137, the magnetic-resistant plate 190 is fixed so as not to float from the main board 120. The double-sided adhesive tape 199 is a kind of bonding member such as an adhesive or a bonding agent.
[0076] Several second protrusions 132 are embedded in holes formed in the magnetic-resistant plate 190. The second mark 137 indicates the bonding position of the double-sided adhesive tape 199 to the main board 120. That is, the second mark 137 is formed in an L-shape, and the area adjacent to the second mark 137 in the first configuration surface 133 (especially the inner corner of the L-shape of the second mark 137) is the second bonding surface to which the double-sided adhesive tape 199 is bonded. The corner of the double-sided adhesive tape 199 is aligned with the L-shape of the second mark 137, and the double-sided adhesive tape 199 is bonded to the second bonding surface of the first configuration surface 133. The magnetic-resistant plate 190 is bonded to the double-sided adhesive tape 199 and fixed to the surface of the main board 120 by the double-sided adhesive tape 199. The thickness of the double-sided adhesive tape 199 is equal to the height difference between the first configuration surface 133 and the second configuration surface 135, or slightly larger than the height difference. The thickness of the double-sided adhesive tape 199 is set such that the height from the first configuration surface 133 to the surface of the antimagnetic plate 190 is equal to the height from the first configuration surface 33 of the electronic timepiece 1 to the surface of the solar cell panel 50, and is thicker than the double-sided adhesive tape 59 of the electronic timepiece 1. The thickness of the double-sided adhesive tape 199 can also be adjusted by thickening the adhesive layer or adhesive layer of the double-sided adhesive tape 199, which is the same for the double-sided adhesive tape 59. The thickness of the double-sided adhesive tape 199 can also be adjusted by thickening the base material of the double-sided adhesive tape 199, which is the same for the double-sided adhesive tape 59.
[0077] The thickness of the antimagnetic plate 190 is equal to the thickness of the spacer 40 of the electronic timepiece 1. The height from the first arrangement surface 133 to the surface of the antimagnetic plate 190 is equal to the height from the first arrangement surface 33 of the electronic timepiece 1 to the surface of the solar panel 50. Therefore, even if the date wheel pressure plate 170, which is the same as the date wheel pressure plate 70 in the electronic timepiece 1, overlaps with the antimagnetic plate 190, the date wheel pressure plate 170, the solar panel 150, and the dial 180 are assembled without shaking.
[0078] (3) Date wheel
[0079] The date wheel 160 is made of a metal material or a resin material. The date wheel 160 is arranged in a ring shape. The date wheel 160 is transparent or opaque. A plurality of characters are printed on the date wheel 160 and punched or engraved. The characters are arranged in a circumferential direction. The date wheel 160 has an internal gear on its inner circumference. The date wheel 160 overlaps the magnetic-resistant plate 190 in a state of floating from the magnetic-resistant plate 190. The date wheel 160 floats from the magnetic-resistant plate 190 because it is supported by the second protrusion 132. Therefore, the date wheel 160 does not receive resistance to the rotation of the date wheel 160 from the magnetic-resistant plate 190.
[0080] (4) Date wheel pressure plate
[0081] The date wheel pressing plate 170 is the same as the date wheel pressing plate 70 of the electronic timepiece 1. The date wheel pressing plate 170 overlaps the antimagnetic plate 190. The outer periphery of the date wheel pressing plate 170 covers the internal gear of the date wheel 160 and is separated from the internal gear 66 or in soft contact with the internal gear 66.
[0082] (5) Solar panels
[0083] The solar panel 150 is provided in a circular and thin sheet shape. The solar panel 150 overlaps with the date wheel 160 and the date wheel pressing plate 170. The solar panel 150 floats from the date wheel 160 because it is supported by the date wheel pressing plate 170. The solar panel 150 has an opening 152 near the periphery. The opening 152 is arranged at the 4 o'clock position. The opening 152 exposes any character of the date wheel 160. The character shows the current date.
[0084] (5) Dial
[0085] The dial 180 is made of a transparent or translucent material and is provided in a circular plate shape and overlaps with the solar cell panel 150 .
[0086] <4. Conclusion>
[0087] The main board 20 of the electronic timepiece 1 has a first mark 36 and a second mark 37 on its surface, and the main board 120 of the electronic timepiece 101 has a first mark 136 and a second mark 137 on its surface. When different components, namely, the solar cell panel 50 and the anti-magnetic plate 190, are mounted on the main boards 20 and 120, respectively, the bonding positions of the double-sided adhesive tapes 59 and 159 are specified by the first mark 36 and the second mark 137, respectively. The positions where the solar cell panel 50 and the anti-magnetic plate 190 are fixed to the main boards 20 and 120, respectively, are also specified by the first mark 36 and the second mark 137, respectively. Therefore, even if the main boards 20 and 120 are the same, the solar cell panel 50 and the anti-magnetic plate 190 that are different from each other can be appropriately mounted on the main boards 20 and 120. In the internal structure (module) of the electronic timepiece 1 and the electronic timepiece 101, since the main boards 20 and 120 are common, the electronic timepiece 1 and the electronic timepiece 101 as sister products can be provided at low cost, and the stock can be increased at low cost.
[0088] The back surface of the solar panel 50 is fixed to the bottom of the first mark 36 by the double-sided adhesive tape 59, so that the height of the surface of the solar panel 50 is consistent with the height of the surface of the spacer 40. Therefore, even if the date wheel pressing plate 70 overlaps with the spacer 40 and the extensions 51a and 51b of the solar panel 50, the date wheel pressing plate 70 does not shake.
[0089] Since the double-sided adhesive tape 59 is bonded to the bottom of the first mark 36, the thickness of the double-sided adhesive tape 59 will not be a major factor in the bending deformation of the solar panel 50. Therefore, even if the date wheel pressing plate 70 overlaps the solar panel 50, the date wheel pressing plate 70 will not shake.
[0090] The date wheel pressing plate 70 extends from the spacer 40 and the edge of the second arrangement surface 35 toward the expansion portions 34a and 34b, and the extended portion covers the extension portions 51a and 51b of the solar panel 50 from the windshield side, pressing the extension portions 51a and 51b to the main board 20. Therefore, the solar panel 50 is firmly attached to the main board 20. Since the extension portions 51a and 51b and the double-sided adhesive tape 59 are alternately arranged in the circumferential direction, the solar panel 50 is firmly attached to the main board 20.
[0091] The antimagnetic plate 190 is bonded to the first arrangement surface 133 by a double-sided adhesive tape 199. The double-sided adhesive tape 199 supports the antimagnetic plate 190 floating from the first arrangement surface 133 from below, thereby stabilizing the antimagnetic plate 190. The double-sided adhesive tape 199 helps prevent the antimagnetic plate 190 from shaking.
[0092] The thickness of the spacer 40 of the electronic timepiece 1 is equal to the thickness of the antimagnetic plate 190 of the electronic timepiece 101. Furthermore, the thickness of the double-sided adhesive tapes 59 and 199 helps to make the height from the first configuration surface 133 to the surface of the antimagnetic plate 190 equal to the height from the first configuration surface 33 to the surface of the solar panel 50 in the electronic timepiece 1. Therefore, even if the date wheel presser 170, which is the same as the date wheel presser 70 in the electronic timepiece 1, overlaps with the antimagnetic plate 190, the date wheel presser 170, the solar panel 150, and the dial 180 are assembled without shaking.
[0093] The antimagnetic plate 190 extends from the edge of the second arrangement surface 135 toward the first arrangement surface 133, and the extended portion covers the motor 121. The extended portion is bonded to the first arrangement surface 133 near the motor 121 using a double-sided adhesive tape 199. Therefore, the extended portion reliably magnetically shields the motor 121.
[0094] like Figure 2 to Figure 5As shown in FIG. 1 , the extensions 51a and 51b of the solar cell panel 50 are pressed toward the board 20 by the date wheel pressing plate 70. Therefore, in order to fix the solar cell panel 50 to the board 20 at the portion other than the extensions 51a and 51b, it is necessary to arrange the double-sided adhesive tape 59 and the first mark 36 avoiding the extensions 51a and 51b. Even if the double-sided adhesive tape 59 and the first mark 36 are not used, and another double-sided adhesive tape is adhered to the surface of the board 20 with the second mark 37 as a target or reference, and the solar cell panel 50 is fixed to the board 20 using the double-sided adhesive tape, since the double-sided adhesive tape and the second mark 37 are arranged near the extensions 51a and 51b, the solar cell panel 50 cannot be firmly fixed to the board 20 at the portion other than the extensions 51a and 51b. In other words, the second mark 37 cannot be used as a target or reference for the bonding position of the double-sided adhesive tape. Therefore, unlike the second mark 37, the first mark 36 is formed on the surface of the panel 120 in the range of 5 o'clock to 7 o'clock and in the range of 9 o'clock to 11 o'clock, and the double-sided adhesive tape 59 is adhered to the surface of the panel 20 with the first mark 36 as the target or reference, and the solar cell panel 50 is firmly fixed to the panel 20 using the double-sided adhesive tape 59.
[0095] On the other hand, Fig. 9 and Fig.10 As shown in FIG. 1 , the longitudinal dimension of the magnetic-resistant plate 190 is smaller than the lateral dimension of the magnetic-resistant plate 190, so the magnetic-resistant plate 190 is arranged to avoid the antenna 111 and the transceiver 112, the antenna 111 is arranged near one first mark 136, and the transceiver 112 is arranged to overlap with another first mark 136. Therefore, the magnetic-resistant plate 190 does not overlap with the first mark 136, or even if the magnetic-resistant plate 190 overlaps with the first mark 136, the overlapping range is small. In this way, even if another double-sided adhesive tape is adhered to the first mark 136, the magnetic-resistant plate 190 cannot be fixed to the plate 120 using the double-sided adhesive tape. In other words, the first mark 136 cannot be used as a target or reference for the adhesion position of the double-sided adhesive tape. Therefore, unlike the first mark 136, the second mark 137 is formed on the surface of the plate 120 at the positions of 2 o'clock, 7 o'clock and 9 o'clock, and the double-sided adhesive tape 199 is adhered to the surface of the plate 120 with the second mark 137 as the target or reference, and the magnetic-resistant plate 190 is firmly fixed to the plate 120 using the double-sided adhesive tape 199.
