The configuration includes an antenna (20) that receives radio waves by winding a coil (21) on an inner core (22) and a metal indicator wheel (30). The antenna (20) includes a magnetic collecting part (25a, 25b). The magnetic collecting part (25a, 25b) has an inner core end (22a, 22b) that protrudes from the end (21a, 21b) of the coil (21) to the outside of the coil (21) in the inner core (22) as a receiving guide plate (24a, 24b) that extends from the inner core end (22a, 22b). When viewed from above, the indicator wheel (30) overlaps with a part of the antenna (20) but does not overlap with at least one part (26a) of the magnetic collecting part (25a, 25b) that protrudes linearly from the coil (21).

Description

Technical Field

[0001] This invention relates to electronic clocks and the configuration structure of antennas and metal indicating components in electronic clocks. Background Technology

[0002] For example, there are known electronic clocks equipped with antennas for receiving standard radio waves containing time information. As an antenna built into the clock, an antenna is formed by winding an insulated metal wire around an inner core of an amorphous material, ferrite material, etc., to form a coil (based on a wire winding).

[0003] Furthermore, an antenna has been proposed where a metal lead plate is connected to an inner core protruding from both ends of the coil and positioned at an offset location in the thickness direction of the clock (see, for example, Patent Document 1). Antennas with lead plates connected in this manner can have the lead plates positioned in a different plane than the inner core. Therefore, the installation space in the same plane as the coil can be reduced while preventing or suppressing a decrease in receiving sensitivity due to a shorter inner core.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2016-090507 Summary of the Invention

[0007] (The problem the invention aims to solve)

[0008] However, if the antenna is covered by metal, the sensitivity of radio wave reception decreases. In clocks, the case, including the back cover, is often made of metal. Therefore, although the back cover side is covered by metal, the dial side is not, and radio wave reception occurs on the dial side.

[0009] However, there are also cases where a metal indicator wheel is configured on the dial side, and in a top view viewed from the dial side, the metal indicator wheel is configured so that it does not cover the antenna.

[0010] In small electronic clocks, such as those for women, the space for component placement is smaller compared to clocks for men, so there are cases where the antenna must be partly covered by a metal indicator wheel.

[0011] The present invention was made in view of the above circumstances, and its object is to provide an electronic clock with an antenna and a metal indicator component configuration structure that can suppress the decrease in antenna receiving sensitivity in an electronic clock in which a metal indicator component covers a portion of the antenna.

[0012] (The measures taken to solve the problem)

[0013] The configuration structure of the antenna and the metal indicating member in the electronic clock of the first aspect of the present invention comprises: an antenna having a coil wound on an inner core to receive radio waves; and a metal indicating member, the antenna having a magnetic collecting portion having an inner core end protruding from the end of the coil outward from the coil, or functioning together with the inner core end as a receiving guide plate extending the inner core end. In plan view, the configuration structure is such that the indicating member overlaps with a portion of the antenna while not overlapping with a portion of the magnetic collecting portion that protrudes linearly from at least one end of the coil.

[0014] The electronic clock of the second aspect of the present invention comprises: an antenna and a metal indicating component in the electronic clock of the present invention.

[0015] (The effect of the invention)

[0016] According to the configuration structure of the antenna and the metal indicating component in the electronic clock of the present invention, in an electronic clock in which the metal indicating component covers a portion of the antenna, it is possible to suppress the decrease in the receiving sensitivity of the antenna.

[0021] Figure 5 To show Figure 4 A top view of the configuration of the antenna and metal indicator wheel in the movement of the electronic clock shown. Detailed Implementation

[0022] Hereinafter, embodiments of the electronic clock of the present invention and the configuration structure of the antenna and metal indicating component in the electronic clock will be described using the accompanying drawings.

[0023] Figure 1 To show a top view of one embodiment of the electronic clock 100, Figure 2 To show Figure 1 A top view of the configuration of the antenna 20 in the movement 1 of the electronic clock 100 shown. Figure 3 To show Figure 2 A top view of the configuration structure of the antenna 20 and the metal indicator wheel 30 in the mechanism 1 shown.

[0024] The illustrated electronic clock 100 is one embodiment of the electronic clock of the present invention. Furthermore, the arrangement of the antenna 20 and the metal indicator wheel 30 in the movement 1 of the electronic clock 100 is one embodiment of the arrangement of the antenna and the metal indicator component in the electronic clock of the present invention.

[0025] Inside the case 91 of the electronic clock 100 are a movement 1, a dial 92, an indicator wheel 30, an antenna 20, and hands such as an hour hand 93, a minute hand 94, and a second hand 95. The hands are driven by a stepper motor in the movement 1 and indicate the time by pointing to the hour mark on the dial 92.

[0026] The dial 92 is formed from resin into a circular plate shape. Therefore, the dial 92 allows radio waves to pass through. At the 6 o'clock position of the dial 92, there is a generally fan-shaped opening 92a with an arc concentric with the arc that forms the outer perimeter of the dial.

[0027] The indicator wheel 30 is made of a metal such as aluminum or aluminum alloy and is formed in the shape of a circular plate. In the indicator wheel 30, the crescent moon symbol representing night and the sun symbol representing day are represented on the surface of the circular plate in diagonally opposite areas (areas spaced 180 degrees apart) that enclose the center of the plate. In one embodiment, as... Figure 3 As shown, the indicator wheel 30 is positioned at the 6 o'clock position.

[0028] The indicator wheel 30 is positioned on the back side of the dial 92 with the arc of the fan-shaped outer periphery of the opening 92a of the dial 92 and the arc of the circular plate arranged as concentric circles. Furthermore, the indicator wheel 30 rotates once every 24 hours with the center of the circular plate as its rotation center.

[0029] Therefore, as Figure 1 As shown, a portion of the circular plate of the indicator wheel 30 can be visually confirmed from the surface side of the electronic clock 100 through the opening 92a. Specifically, during the time period corresponding to daytime, the sun image can be visually confirmed through the opening 92a, and during the time period corresponding to nighttime, the crescent moon image can be visually confirmed through the opening 92a. Thus, by visually confirming the indication of the indicator wheel 30 through the opening 92a, it is possible to determine at a glance whether it is day or night.

[0030] The electronic clock 100 includes a stem 96 extending from the movement 1 to the outside of the case 91, and a crown 97 for rotating the stem 96 is fixed at its front end. The hands are calibrated by rotating the stem 96 to rotate the hands. In this embodiment, the stem 96 of the electronic clock 100 is located at the 3 o'clock position on the dial 92.

[0031] Antenna 20 is used to receive standard radio waves containing time information, and electronic clock 100 automatically adjusts the position of its pointer based on the standard radio waves received by antenna 20.

[0032] like Figure 2 As shown, antenna 20 has a structure comprising an inner core 22, a coil 21, connecting blocks 23a and 23b, and receiving guide plates 24a and 24b. Antenna 20 is configured such that the center of coil 21 is located at the 7:30 position on dial 92.

[0033] The inner core 22 is formed of, for example, ferrite. The inner core 22 is integrally formed of a core 22c around which an electric wire is wound as a coil 21, and ends 22a and 22b (inner core ends) connected to the core 22c and protruding outward from both ends 21a and 21b of the coil 21. The core 22c and ends 22a and 22b are formed in a straight line. The electric wire is not wound around ends 22a and 22b. The ends 22a and 22b protruding from one end of the coil 21 and from the other end of the coil 21 are set to have equal lengths along the length direction of the core 22c.

[0034] At the end 22a, a cuboid connecting block 23a of ferrite with a specified thickness is connected to the extended portion that protrudes linearly from the coil 21, i.e., the extension line L of the linear core 22c (for example, at approximately the 9 o'clock position on the dial 92).

[0035] Similarly, at the end 22b, the extended portion that protrudes linearly from the coil 21, i.e., the extension line L of the linear core 22c (for example, at approximately the 6 o'clock position on the dial 92), is also connected to a cuboid-shaped connecting block 23b formed of ferrite with a specified thickness.

[0036] The two connecting blocks 23a and 23b can be formed with the same thickness, but they can also be formed with different thicknesses.

[0037] The receiving guide plates 24a and 24b are arc-shaped flat plates, both made of amorphous material (magnetic material). The arcs of the receiving guide plates 24a and 24b are concentric with the arcs of the outer periphery of the dial 92.

[0038] The receiving guide plate 24a is connected to the side of the cuboid connecting block 23a opposite to the side connected to the end 22a (the side opposite in the thickness direction). Thus, the end 22a of the inner core 22 and the receiving guide plate 24a are configured to be offset in the thickness direction of the electronic clock 100 by the thickness of the connecting block 23a, thereby preventing the antenna 20 from occupying a larger area in the same plane and increasing the flexibility of the antenna 20's configuration.

[0039] Similarly, the receiving guide plate 24b is connected to the side of the cuboid connecting block 23b opposite to the side connected to the end 22b (the side opposite in the thickness direction). Thus, the end 22b of the inner core 22 and the receiving guide plate 24b are configured to be offset in the thickness direction of the electronic clock 100 by the thickness of the connecting block 23b, thereby preventing the antenna 20 from occupying a larger area in the same plane and increasing the degree of freedom in the configuration of the antenna 20.

[0040] The ends 22a and 22b of the inner core 22, the connecting blocks 23a and 23b, and the receiving guide plates 24a and 24b are provided to improve the receiving sensitivity of standard radio waves. These ends 22a and 22b, connecting blocks 23a and 23b, and receiving guide plates 24a and 24b constitute the magnetic collecting parts 25a and 25b for collecting radio waves. Thus, the receiving guide plates 24a and 24b extend the ends 22a and 22b of the inner core 22 respectively and function as antennas 20.

[0041] In this embodiment, the receiving guide plate 24a is set to be longer than the receiving guide plate 24b. Therefore, the magnetic collecting part 25a, which is composed of the end 22a of the inner core 22, the connecting block 23a, and the receiving guide plate 24a, is longer than the magnetic collecting part 25b, which is composed of the end 22b of the inner core 22, the connecting block 23b, and the receiving guide plate 24b.

[0042] like Figure 3 As shown, the antenna 20 configured in this way is positioned on the back side of the dial 92 and the indicator wheel 30. When viewed from above in the thickness direction of the electronic clock 100, only a portion of the coil 21 in the antenna 20 near the 6 o'clock position on the dial 92 overlaps with the indicator wheel 30.

[0043] Furthermore, although a portion of the antenna 20 overlaps with the indicator wheel 30 when viewed from above in the thickness direction of the electronic clock 100, the indicator wheel 30 is not overlapped on the portions 26a, 26b of the magnetic collecting sections 25a, 25b that protrude linearly from the coil 21 (the ends 22a, 22b of the inner core 22, the connecting blocks 23a, 23b, and the portions of the receiving guide plates 24a, 24b along the extension line L of the core 22c). That is, in the configuration structure of the antenna and the metal indicator component in the electronic clock of this embodiment, when viewed from above, the indicator wheel 30 overlaps with a portion of the antenna 20 but does not overlap with the portion 26b of the magnetic collecting sections 25a, 25b that protrude linearly from at least one end of the coil 21.

[0044] In the electronic clock 100, the back side is covered by a metal case (back cover) that shields standard radio waves, while the front side is equipped with a crystal and a resin dial 92 that allow standard radio waves to pass through. Therefore, the antenna 20 of the electronic clock 100 receives standard radio waves incident from the front side of the electronic clock 100.

[0045] However, it is generally believed that the metal component is positioned closer to the front side of the antenna 20 than the antenna 20, and that the metal component overlaps with the antenna 20 when viewed from above, which is the reason for the decrease in the reception sensitivity of standard radio waves based on the antenna 20.

[0046] In contrast, according to the research of the inventors of this application, as long as the magnetic collecting parts 25a and 25b in the antenna 20, the portions 26a and 26b that protrude linearly from the coil 21, are configured such that they do not overlap with the metal components, the receiving sensitivity will not decrease significantly.

[0047] The reasoning is as follows: the magnetic field lines distributed on the outside of the coil 21 converge at the ends 22a and 22b of the inner core 22, causing the magnetic field lines to return to the inside of the coil 21. Therefore, the density of magnetic field lines at the antenna 20 is greater than that in other parts. Covering the part with a high density of magnetic field lines with a metal component will cause a significant decrease in receiving sensitivity.

[0048] Therefore, it is believed that, similar to the ends 22a and 22b of the inner core 22, the metal components covering the magnetic collecting parts 25a and 25b, and the portions 26a and 26b that protrude linearly from the coil 21, will also cause a significant decrease in receiving sensitivity.

[0049] Furthermore, according to the inventor's research, in antennas where the lengths of the magnetic collecting section 25a and the magnetic collecting section 25b are different, even if the portion 26b protruding linearly from the coil 21 in the shorter magnetic collecting section 25b overlaps with a metal component, as long as the configuration structure in which the portion 26a protruding linearly from the coil 21 in the longer magnetic collecting section 25a does not overlap with a metal component, the receiving sensitivity will not decrease significantly.

[0050] The reason is as follows: the density of magnetic field lines in the longer magnetic collecting part 25a, which protrudes linearly from the coil 21, is greater than the density of magnetic field lines in the shorter magnetic collecting part 25b, which protrudes linearly from the coil 21. Covering the part with the greater density of magnetic field lines with a metal component would cause a significant decrease in receiving sensitivity.

[0051] In contrast, in the configuration of the antenna 20 and the indicator wheel 30 of this embodiment, when viewed from above, the metal indicator wheel 30 does not overlap with the portion 26a of the longer magnetic collecting section 25a that protrudes linearly from the coil 21. Therefore, there is no decrease in the receiving sensitivity of the standard radio waves based on the antenna 20, or a significant decrease in receiving sensitivity can be suppressed. Furthermore, as long as the end 21a of the coil connected to the relatively longer magnetic collecting section 25a also does not overlap with the metal component, the decrease in receiving sensitivity is further suppressed, which is therefore preferable.

[0052] As described above, even if the antenna 20 and the metal indicator wheel 30 have to overlap when viewed from above due to reasons such as the small size of the electronic clock 100, the configuration structure of the electronic clock 100 and the configuration structure of the antenna 20 and the metal indicator wheel 30 in the electronic clock 100 according to this embodiment can prevent or suppress the decrease in the receiving sensitivity of the antenna.

[0053] Next, refer to Figure 4 , 5 Other embodiments of the electronic clock and other embodiments of the configuration structure of the antenna and metal indicating component in the electronic clock of the present invention will be described. Furthermore, descriptions that are repeated in the above-described embodiment will be omitted. Figure 4 A top view illustrating another embodiment of an electronic clock. Figure 5 To show Figure 4 A top view of the configuration of the antenna and metal indicator wheel in the movement of the electronic clock shown.

[0054] like Figure 4As shown, the electronic clock 101 has a movement 2, a dial 92, an indicator wheel 30, an antenna 20, an hour hand 93, a minute hand 94, and a second hand 95 inside its case 91. A roughly fan-shaped opening 92a is formed at the 5 o'clock position on the dial 92. (As shown...) Figure 5 As shown, the pointer wheel 30 is positioned at the 5 o'clock position so that a portion of the circular plate of the pointer wheel 30 can be visually confirmed from the surface side of the electronic clock 101 through the opening 92a.

[0055] Antenna 20 includes an inner core 22, a coil 21, connecting blocks 23a and 23b, and receiving guide plates 24a and 24b. The ends 22a and 22b of the inner core 22, the connecting blocks 23a and 23b, and the receiving guide plates 24a and 24b constitute magnetic collecting parts 25a and 25b. The receiving guide plates 24a and 24b extend the ends 22a and 22b of the inner core 22, respectively, and function as antenna 20.

[0056] Antenna 20 is located on the back side of dial 92 and indicator wheel 30. For example... Figure 5 As shown, in this embodiment, when viewed from above in the thickness direction of the electronic clock 101, the antenna 20 and the indicator wheel 30 are arranged on the indicator wheel 30 at the 5 o'clock position, overlapping part of the antenna 20 (i.e., overlapping the receiving guide plate 24b of the magnetic collecting part 25a), while the portions 26a and 26b of the magnetic collecting parts 25a and 25b that protrude linearly from the coil 21 are arranged in a configuration that does not overlap with the indicator wheel 30.

[0057] That is, in the configuration structure of the antenna and the metal indicator component in the electronic clock of this embodiment, when viewed from above, the indicator wheel 30 is configured such that while it overlaps with a part of the antenna 20, the indicator wheel 30 does not overlap with either the portion 26a that protrudes linearly from one end of the coil 21 in the magnetic collection portions 25a and 25b, nor with the portion 26b that protrudes linearly from the other end of the coil 21.

[0058] As mentioned above, it is generally believed that the metal component is positioned closer to the front side of the antenna 20 than the antenna 20, and that this metal component overlaps with the antenna 20 when viewed from above, which is the reason for the decrease in the reception sensitivity of standard radio waves based on the antenna 20.

[0059] In contrast, in the configuration of the antenna 20 and the indicator wheel 30 of this embodiment, when viewed from above, the metal indicator wheel 30 does not overlap with the portions 26a and 26b of the magnetizing portions 25a and 25b that protrude linearly from the coil 21. Therefore, according to the electronic clock 101 of this embodiment and the configuration of the antenna 20 and the metal indicator wheel 30 in the electronic clock 101, there is no decrease in the receiving sensitivity of the standard radio waves based on the antenna 20, or a significant decrease in receiving sensitivity can be suppressed.

[0060] In the configuration structure of the electronic clock 100, 101 and the metal indicator wheel 30 in the electronic clock 100, 101 of the present invention, the antenna 20 is a separate antenna structure that connects the antenna body (coil 21 and inner core 22) and the receiving guide plates 24a, 24b through connecting blocks 23a, 23b.

[0061] However, in the configuration structure of the electronic clock and the antenna and metal indicating component in the electronic clock of the present invention, the antenna 20 is not limited to a separate structure. That is, in the embodiment of the present invention, the inner core 22 in the antenna body can be extended to be the same length as the receiving guide plates 24a and 24b, so that a portion of the extended inner core 22 also functions as the receiving guide plates 24a and 24b. In this case, the connecting blocks 23a and 23b are not required.

[0062] Thus, even if the antenna 20 is an integrated structure in which the antenna body and the receiving guide plates 24a and 24b are formed as one piece, when viewed from above, the metal indicator wheel 30 and the magnetic collection parts 25a and 25b, the portions 26a and 26b that protrude linearly from the coil 21, or at least the portion 26 protruding linearly from the coil 21 in the magnetic collection part 25a, can not overlap. This configuration can prevent or suppress the decrease in the receiving sensitivity of standard radio waves based on the antenna 20.

[0063] The above describes the configuration structure of the antenna and the metal indicating component in the electronic clock of the present invention, as well as the implementation method of the electronic clock. However, the present invention is not limited to the above implementation method and various changes or modifications can be made.

[0064] In the configuration structure of the electronic clocks 100 and 101, antenna 20, and metal indicator wheel 30 of the embodiments of the present invention, the antenna 20 is used to receive standard radio waves. However, the antenna in the configuration structure of the electronic clock, antenna, and metal indicator component of the present invention is not limited to receiving standard radio waves, and may also receive other radio waves.

[0065] Furthermore, in the configuration structure of the electronic clocks 100 and 101, antenna 20, and metal indicator wheel 30 of the embodiments of the present invention, the indicator wheel 30 is a component for visually confirming whether it is day or night. However, the indicator component in the configuration structure of the electronic clock, antenna, and metal indicator component of the present invention is not limited to a component for visually confirming whether it is day or night. It may be a component that displays the age of the month by displaying a graphic corresponding to the waxing and waning of the moon, or a component that displays the date and day of the week.

[0066] Furthermore, in the configuration structure of the electronic clock 100, 101, antenna 20, and metal indicator wheel 30 of the embodiments of the present invention, the indicator wheel 30 is a component that indicates a specific matter by rotating. However, in the configuration structure of the electronic clock, antenna, and metal indicator component of the present invention, the indicator component may not be a rotating indicator wheel, but may be a component that indicates a specific matter when stationary.

[0067] In embodiments of the present invention, the magnetizing section 25a is formed by the end portion 22a of the inner core 22, the connecting block 23a, and the receiving guide plate 24a, and the magnetizing section 25b is formed by the end portion 22b of the inner core 22, the connecting block 23b, and the receiving guide plate 24b. However, it is also possible to omit the connecting blocks 23a and 23b and omit the receiving guide plates 24a and 24b, and instead form the magnetizing section 25a solely by the end portion 22a of the inner core 22, or to form the magnetizing section 25b solely by the end portion 22b of the inner core 22. Furthermore, in embodiments of the present invention, the magnetizing section 25a and the magnetizing section 25b are formed with different lengths, but they may also be formed with the same length.

[0068] also, Figures 1-3 The configuration of the electronic clock 100, antenna 20, and metal indicator wheel 30 in one embodiment shown is such that, when viewed from above, the indicator wheel 30 does not overlap with the portion 26a, 26b that protrudes linearly from both ends of the coil 21, and the portion 26a that protrudes linearly from the coil 21 in the longer magnetizing portion 25a. This configuration does not include a configuration where, when viewed from above, both portions 26a, 26b that protrude linearly from the coil 21 overlap with the indicator wheel 30.

[0069] However, when the inner core 22 does not protrude from both ends of the coil 21, but only from one end of the coil 21 and not from the other end of the coil 21, the configuration structure of the antenna and the metal indicator component included in the electronic clock and electronic clock of the present invention is as long as the indicator wheel 30 does not overlap with the end of the inner core 22 protruding from the coil 21 when viewed from above.

[0070] also, Figure 4 , Figure 5The other configurations of the electronic clock 101, antenna 20, and metal indicator wheel 30 shown in this embodiment are such that, when viewed from above, the portions 26a and 26b of the magnetic collecting parts 25a and 25b that protrude linearly from the coil 21 do not overlap with the indicator wheel 30. Furthermore, when the inner core 22 does not protrude from both ends of the coil 21, but only from one end of the coil 21 and not from the other end, the configuration of the indicator wheel 30 not overlapping with the portion of the magnetic collecting part protruding linearly from the coil 21 on the side protruding from the coil 21 when viewed from above is included in the configuration of the electronic clock and the antenna and metal indicator component in the electronic clock of the present invention.
