The substrate 3 is formed with wiring 32 that electrically connects the communication IC 31 and the conductive member 6. The board 3 is formed with an insertion hole 33 into which the bolt 13 for fixing the conducting member 6 is inserted.

  The ground plane 4 is disposed between the antenna member 2 and the substrate 3 in the axial direction. The ground plane 4 is made of metal or an insulator (made of resin or ceramic), and is formed in a disk shape with unevenness when viewed from the axial direction. The base plate 4 accommodates various devices constituting the movement MM, for example, the battery 8, the step motors 9 and 10, the date wheel 11 and the like in the internal space. The ground plate 4 has the antenna member 2 attached to an end portion on the upper direction Z1 side in the axial direction. In the present embodiment, the antenna member 2 is attached to the ground plate 4 by a locking claw (not shown) formed on the first conducting member 5 attached to the antenna member 2 so as to protrude downward in the downward direction Z2 on the outer peripheral surface 4a of the ground plate 4. It is performed by being locked to the formed locking receiver. In addition, the base plate 4 has the substrate 3 attached to the end portion on the lower Z2 side in the axial direction. The mounting of the substrate 3 to the base plate 4 in the present embodiment is performed by inserting the bolts 13 into the insertion holes 33 formed in the base plate 3 and screwing the bolts 13 into the screw grooves formed in the base plate 4. The base plate 4 is formed with a recess 41 that is recessed radially inward on the outer peripheral surface 4a. The concave portion 41 is provided with the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62, and is formed by denting a part of the outer peripheral surface 4a radially inward.

  The bent part (first contact part) 5 is a first contact part and conducts the antenna member 2 and the substrate 3. The bent portion (first contact portion) 5 in the present embodiment is made of metal and is formed integrally with the antenna member 2 as shown in FIGS. 5 and 7. The bent portion (first contact portion) 5 is in electrical contact with the arm portion (second contact portion) 62. The bent portion (first contact portion) 5 is formed in a recess 24 that is recessed radially inward on the outer periphery of the antenna member 2. The bent portion (first contact portion) 5 is formed so as to protrude in the downward direction Z2 side, that is, the substrate direction side in the concave portion 24. Here, the bent portion (first contact portion) 5 is formed by bending a piece portion formed to protrude radially outward from the outer periphery of the antenna member 2 to the substrate direction side. The bent portion (first contact portion) 5 is disposed on the outer side in the radial direction than the outer peripheral surface 4a of the base plate 4, and is located in the concave portion 41 when viewed from the axial direction in the present embodiment. That is, the bent portion (first contact portion) 5 is disposed on the radially outer side than the outer peripheral surface 4 a of the main plate 4. The bent portion (first contact portion) 5 is formed in a rectangular shape when viewed from the radial direction. As shown in FIG. 8, the bent portion (first contact portion) 5 is formed with a contact surface 5 a that is in electrical contact with a later-described contact surface 62 a of the arm portion (second contact portion) 62. As shown in FIG. 7, the contact surface 5 a is formed so as to intersect the axial direction when viewed from the radial direction. The contact surface 5a is formed at the lower end Z2 side end of the arm portion direction W1 end in the contact direction. The contact surface 5a in this embodiment is formed in the inclined surface which goes to the bending part direction W2 side as it goes to the downward direction Z2. Here, the contact direction is a direction along the outer peripheral surface 4a of the main plate 4 when viewed from the radial direction, and refers to, for example, a circumferential direction or a tangential direction of the movement MM.

  The conducting member 6 conducts the antenna member 2 and the substrate 3. The conducting member 6 is made of metal, and has a main body 61 and an arm (second contact portion) 62 as shown in FIG. The main body 61 is a flat plate and is fixed to the upper direction Z <b> 1 side in the axial direction with respect to the substrate 3. The main body 61 is opposed to the insertion hole 33 of the substrate 3 in the axial direction, and an insertion hole 61a into which the bolt 13 is inserted is formed. The main body 61 in the present embodiment includes a wiring (see FIG. 3) formed on the surface on the upper direction Z1 side of the both surfaces in the axial direction of the substrate 3 among the both surfaces in the axial direction. It is fixed to the substrate 3 while being in electrical contact. The arm part (second contact part) 62 is a second contact part and is in electrical contact with the bent part (first contact part) 5. The arm part (second contact part) 62 is formed so as to protrude from the outer periphery of the main body part 61 to the upper direction Z1 side, that is, the antenna member direction side. The arm part (second contact part) 62 is disposed on the outer side in the radial direction than the outer peripheral surface 4a of the main plate 4, and is located in the recess 41 when viewed from the axial direction in the present embodiment. That is, the conducting member 6 has at least a part of the arm portion (second contact portion) 62 arranged on the outer side in the radial direction than the outer peripheral surface 4 a of the base plate 4. Therefore, since the first conducting member 5 and the conducting member 6 are located in the recess 41, the distance from the center O of the first conducting member 5 and the conducting member 6 can be made equal to or less than the radius of the ground plane 4. Thereby, by arranging the first conducting member 5 and the conducting member 6 radially outside the outer peripheral surface 4a of the base plate 4, it is possible to suppress an increase in the outer diameter of the movement MM. The arm part (second contact part) 62 is formed so as to be elastically deformable with respect to the main body part 61 and, as shown in FIG. 9, is a long plate shape that extends in the vertical direction when viewed from the contact direction. Is formed. The arm portion (second contact portion) 62 is formed with a contact surface 62 a that is in electrical contact with the contact surface 5 a of the first conduction member 5. When viewed from the radial direction, the contact surface 62a is formed at an upper end Z1 side end portion of the arm portion (second contact portion) 62, that is, a tip end portion 62b. Here, the arm part (second contact part) 62 is a part of the arm part (second contact part) 62 in which the width (length in the radial direction) of the tip part 62b is different from the tip part 62b, that is, the tip part 62b. The width of the portion on the lower direction Z2 side is wider than that. That is, the contact surface 62a is formed wider in the radial direction than a portion different from the tip end portion 62b. As shown in FIG. 10, the arm portion (second contact portion) 62 protrudes upward from the main body portion 61 in a state where no external force is acting, and the tip end portion 62 b is directed toward the arm portion direction W <b> 1. It is formed to be inclined with respect to the main body 61. The arm portion (second contact portion) 62 faces the bent portion (first contact portion) 5 in the vertical direction in the pre-assembly state where no external force is applied, and in this embodiment, the tip portion 62b faces the contact surface 5a. To do. Here, as shown in FIG. 7, with the antenna member 2, the substrate 3, the first conducting member 5 and the conducting member 6 attached to the ground plate 4, the contact surface 62a and the contact surface 5a are electrically connected in the contact direction. The first conducting member 5 and the conducting member 6 are brought into contact with each other. In the contact state, the arm part (second contact part) 62 is elastically deformed in a direction opposite to the bending part (first contact part) 5 in the contact direction, that is, the arm part direction W1.

  The middle frame 7 is interposed between an inner wall (not shown) of the outer case and the ground plate 4 in a state where the movement MM is housed in the housing space of the outer case, and functions as a spacer. The middle frame 7 is made of synthetic resin or the like and has an insulating property, and is formed in a cylindrical shape as shown in FIGS. 1 and 3. The middle frame 7 is disposed on the outer side in the radial direction than the outer peripheral surface 4a of the base plate 4. When viewed from the axial direction, the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 are provided. It is located between the recess 41 of the main plate 4. The middle frame 7 is attached to the main plate 4 by a locking mechanism (not shown). As shown in FIG. 6, the middle frame 7 has a notch 71 formed in a portion facing the recess 41 in the radial direction. The notch 71 communicates from the outer peripheral surface 7 a of the middle frame 7 to the inner peripheral surface (not shown), and is formed so that the recess 41 is exposed to the outside from the middle frame 7. The cutout portion 71 in the present embodiment has a portion cut out from the lower end Z2 side end portion upward in the outer peripheral surface 7a. Therefore, the notch 71 has at least the arm portion (second contact portion) 62 among the arm portion (second contact portion) 62 and the bent portion (first contact portion) 5 in the contact state where the recess 41 is disposed. It can be visually recognized from the outside of the middle frame 7. Here, when the arm portion (second contact portion) 62 is in a contact state, the worker visually recognizes the elastic deformation of the arm portion (second contact portion) 62 because the arm portion (second contact portion) 62 is elastically deformed in the arm portion direction W1 side. By doing so, even if the middle frame 7 is attached to the main plate 4, the contact state of the first conductive member 5 and the conductive member 6 can be confirmed. In addition, the notch part 71 may make it possible to visually recognize the contact surface 5a and the contact surface 62a in a contact state from the outside of the middle frame 7 by widening a region to be cut away from the outer peripheral surface 7a. Further, when viewed from the axial direction, the middle frame 7 is interposed between the outer case and the communication related area S described later, and the outer case can be separated from the communication related area S. When is a metal member, it can suppress that an exterior case influences a communication state.

  As shown in FIG. 3, the battery 8 supplies power to the substrate 3 to drive driving devices such as the step motors 9 and 10 of the electronic timepiece 1. The battery 8 in this embodiment is a secondary battery, and can store the power generated by the solar cell 23. The battery 8 is inserted into and accommodated in the internal space of the base plate 4 from the surface on the lower direction Z2 side of both surfaces in the axial direction of the substrate 3. When viewed from the axial direction, the battery 8 is disposed on the opposite side to the communication related region S including the communication IC 31, the conductive member 6, and the wiring 32 with the center of the substrate 3, that is, the center O of the movement MM interposed therebetween. Yes. That is, when viewed from the axial direction, the battery 8 is disposed at a position away from a target related to communication. Here, the battery 8 is a large metal part in the movement MM, and may affect the communication state such as generation of noise. Therefore, it is possible to prevent the battery 8 from affecting the communication state due to the battery 8 being away from the communication related area S.

  As shown in FIG. 3, the step motors 9 and 10 are driven by electric power from the battery 8 supplied to the substrate 3. The step motors 9 and 10 in the present embodiment are converters, and rotate hands such as a second hand, a minute hand, and an hour hand (not shown) by rotating the pointer rotating shaft 12. The step motors 9 and 10 are accommodated in the internal space of the main plate 4. The step motors 9 and 10 are arranged to face each other across the center of the substrate 3, that is, the center O of the movement MM, when viewed from the axial direction. The step motors 9 and 10 in this embodiment are arranged between the battery 8 and the communication related area S. That is, the step motors 9 and 10 are arranged at positions away from the object related to communication when viewed from the axial direction. Here, the step motors 9 and 10 are large metal parts in the movement MM, like the battery 8, and may affect the communication state such as generation of noise. Therefore, it is possible to suppress the step motors 9 and 10 from affecting the communication state because the step motors 9 and 10 are separated from the communication related area S. It should be noted that metal parts such as a crown and a push button (not shown) are also preferably arranged at positions away from the communication related area S.

  As shown in FIG. 1, the date dial 11 is partially exposed from the date window 22 formed on the antenna member 2, and recognizes the date based on the time inside the clock to the user who uses the electronic timepiece 1. It is something to be made. The date dial 11 is disposed on the lower side Z2 side of the antenna member 2 and is rotated by one of the step motors 9 and 10. Here, when viewed from the axial direction, the date window 22 is located at a position not facing the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 on the radially outer side of the antenna member 2. Is formed. In other words, the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 are positions different from the positions facing the date window 22 on the radially outer side of the date window 22 when viewed from the axial direction. Is provided. Therefore, by separating the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 from the date window 22 formed on the antenna member 2, the antenna member 2 and the bent portion (first contact) are separated. In the vicinity of the portion of electrical contact with the portion 5, the formation of a hole in the antenna member 2 can be suppressed. Thereby, the antenna member 2 can be used effectively as an antenna.

  Next, assembly of the movement MM will be described. First, the worker assembles step motors 9, 10 and the like to the main plate 4. Next, as shown in FIG. 10, the worker assembles the conductive member 6 and the substrate 3 with respect to the base plate 4. Here, the worker screws the bolt 13 inserted into the insertion hole 33 of the substrate 3 and the insertion hole 61 a of the conduction member 6 into the ground plate 4 with the conductive member 6 sandwiched between the ground plate 4 and the substrate 3. By joining, the conducting member 6 and the substrate 3 are fixed to the ground plane 4. At this time, the arm portion (second contact portion) 62 is located in the recess 41. Next, the worker assembles the first conductive member 5 and the antenna member 2 that are fixed to the antenna member 2 in advance with respect to the base plate 4. Here, the worker holds the antenna member 2 and the first conductive member 5 with respect to the ground plane 4 so that the bent portion (first contact portion) 5 faces the arm portion (second contact portion) 62 in the vertical direction. By making the antenna member 2 and the first conductive member 5 approach the lower direction Z2 with respect to the base plate 4 while facing each other, the bending portion (first contact portion) 5 is inserted into the concave portion 41 and the pointer with respect to the through hole 21 The rotating shaft 12 is inserted. As a result, the contact surface 5a of the bent portion (first contact portion) 5 comes into contact with the contact surface 62a of the arm portion (second contact portion) 62, thereby bringing the contact surface 5a and the contact surface 62a into contact as shown in FIG. The arm part (second contact part) 62 is elastically deformed in the arm part direction W <b> 1 with respect to the bending part (first contact part) 5 while maintaining the state of contact with each other. Next, the worker attaches the middle frame 7 to the main plate 4. Here, the worker makes the middle frame 7 face the base plate 4 so that the notch 71 faces the arm portion (second contact portion) 62 in the radial direction, and places the middle frame 7 against the base plate 4. The middle frame 7 is fixed to the main plate 4 by approaching in any direction of the vertical direction. Thereby, the movement MM is assembled.

  As described above, in the electronic timepiece 1 according to the present embodiment, the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 are respectively arranged on the outer side in the radial direction from the outer peripheral surface 4a of the base plate 4, And when it sees from radial direction, the bending part (1st contact part) 5 and the arm part (2nd contact part) 62 in the state which the arm part (2nd contact part) 62 elastically deformed in the arm part direction W1. Since the antenna member 2, the substrate 3, the first conducting member 5 and the conducting member 6 are assembled to the ground plane 4, the bent portion (first contacting portion) 5 and the arm portion Since the (second contact portion) 62 is in electrical contact with the outer peripheral surface 4a of the main plate 4 on the outer side in the radial direction, the antenna member 2 formed by the first conductive member 5 and the conductive member 6 also in the movement MM after assembly. Check electrical connection between board and board 3 Rukoto can.

  Moreover, since the contact surface 62a formed in the front-end | tip part 62b of the arm part (2nd contact part) 62 is widely formed in radial direction rather than the part different from the front-end | tip part 62b, it is a bending part (1st contact). Part) 5 and the arm part (second contact part) 62 are in electrical contact with each other, the contact surface 5a comes into contact with the wide contact surface 62a. Regardless of the dimensional accuracy of the member 2, the substrate 3, the first conducting member 5, and the conducting member 6, the contact surface 5 a and the contact surface 62 a can be reliably brought into contact when the movement MM is assembled.

  Further, the contact surface 5a formed on the bent portion (first contact portion) 5 is formed so as to intersect the axial direction when viewed from the radial direction, so that the contact surface 5a is parallel to the axial direction. Compared with the case where it forms, it can contact reliably. Moreover, the contact surface 5a is formed in the inclined surface which goes to the bending part direction W2 side as it goes to the downward direction Z2, and goes to the arm part direction W1 side as it goes to the downward direction Z2 by elastically deforming. Thus, the intersection with the contact surface 62a of the arm portion (second contact portion) 62 that bends in this manner can be reduced. Therefore, the contact area between the contact surface 5a and the contact surface 62a can be increased, and the contact state can be reliably maintained.

  Further, since the bent portion (first contact portion 5) is formed integrally with the antenna member 2, it is possible to reduce the number of parts and make the movement MM thinner. The bent portion (first contact portion) 5 may be formed as a separate member that is electrically connected to the antenna member 2.

  In the electronic timepiece 1 according to the present embodiment, the bent portion (first contact portion) 5 is formed on the antenna member 2 and the arm portion (second contact portion) 62 is formed on the conducting member 6, but the present invention is not limited thereto. It is not something. For example, an arm part (second contact part) may be formed on the antenna member 2, and a bent part (first contact part) may be formed on the conductive member 6. Moreover, you may form the bending part which carries out an elastic deformation in both the 1st conduction | electrical_connection member 5 and the conduction | electrical_connection member 6. FIG.

  Moreover, in the electronic timepiece 1 in the present embodiment, the contact surface 5a is formed as an inclined surface, but is not limited to this, and may be a curved surface.

  In the electronic timepiece 1 according to the present embodiment, the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 are disposed in the concave portion 41 of the main plate 4, but the present invention is not limited to this. FIG. 11 is a plan view of a movement of an electronic timepiece according to a modification. The bending part (first contact part) 5 and the arm part (second contact part) 62 only need to be arranged on the outer side in the radial direction of the main plate 4. For example, as shown in FIG. A concave portion 72 that is recessed radially outward in the surface 7 b is formed, and the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 may be disposed in the concave portion 72. In this case, the bent portion (first contact portion) 5 and the arm portion (second contact portion) 62 are located radially outside the outer diameter of the main plate 4. It is located between the main plate 4 and does not affect the outer diameter of the movement MM.

  In the electronic timepiece 1 according to the present embodiment, the contact surface 62a is formed wider in the radial direction than the portion different from the tip end portion 62b. However, the present invention is not limited to this, and the contact surface 5a You may form widely in radial direction rather than the part different from the front-end | tip part (downward Z2 side edge part). Moreover, both the contact surface 5a and the contact surface 62a may be widely formed in the radial direction.
