[0061] Hereinafter, an embodiment of the present invention (hereinafter referred to as the present embodiment) will be described in detail based on the drawings.

[0062] First, refer to Figure 1 , Figure 2 , the overall structure of the electronic clock 100 of this embodiment is described. Figure 1 , Figure 2 It is a top view showing the electronic timepiece according to the present embodiment.

[0063] exist Figure 1 , an example is shown in which a subdial 141 having a function hand 141a is disposed adjacent to an hour mark indicating 12 o'clock, and a subdial 142 having a function hand 142a is disposed adjacent to an hour mark indicating 6 o'clock. Figure 2, an example is shown in which a subdial 141 equipped with a function hand 141a is disposed adjacent to an hour mark indicating 11 o'clock, and a subdial 142 equipped with a function hand 142a is disposed adjacent to an hour mark indicating 5 o'clock. Figure 1 The electronic clock 100 and Figure 2 The arrangement of the buttons 20 of the illustrated electronic timepiece 100 is the same.

[0064] In this embodiment, the following structure is adopted: the built-in movement 1 is shared, and Figure 1 and Figure 2 As shown in the example, the arrangement of the sub-dials 141 and 142 as the function display portion can be varied. That is, a structure is adopted in which the electronic timepiece 100 having different appearances can be produced using one movement 1. Figure 1 , Figure 2 Although only two variations are shown, the structure of this embodiment can realize five variations as described later.

[0065] The electronic timepiece 100 includes an outer case 10 including a body 110 and a back cover (not shown), a dial 14 housed in the outer case 10, and a minute hand 16 and an hour hand 17 which are rotationally driven around a pointer shaft 18 to indicate the time.

[0066] Hour marks 49 are provided at predetermined positions on the dial 14. In addition, band fixing portions 11 for fixing a band extend from side surfaces of the outer case 10 at the 12 o'clock side and the 6 o'clock side.

[0067] The electronic timepiece 100 also includes a windshield (not shown) made of a transparent material such as glass so as to cover the dial 14. The windshield is attached to the body 110 of the outer case 10. A back cover is attached to the body 110 on the opposite side of the windshield.

[0068] In this embodiment, the side where the windshield is provided is referred to as the front side, and the side where the back cover is provided is referred to as the back side. Figure 1 , Figure 2 , the electronic timepiece 100 is shown as viewed from the front side.

[0069] In addition, a subdial 141 is provided on the dial 14. The subdial 141 has a circular edge 141b when viewed from above, and a function needle 141a and a scale (not shown) are arranged inside the edge 141b. The edge 141b may be, for example, an edge of an opening formed in the dial 14. Various functions of the electronic clock 100, such as the day of the week, the time zone, the presence or absence of daylight saving time, the reception status of radio waves, and the remaining battery level, can be displayed by the function needle 141a and the scale. Alternatively, the time display such as the second display may be performed by the function needle 141a and the scale.

[0070] In addition, a subdial 142 is provided on the dial 14. The subdial 142 has a circular edge 142b when viewed from above, and a function needle 142a and scales (not shown) are arranged inside the edge 142b. The edge 142b may be, for example, an edge of an opening formed in the dial 14. The function needle 142a and the scales may be used to display functions different from the function needle 141a and the scales included in the subdial 141.

[0071] In addition, Figure 1 , Figure 2 In the example of providing two sub dials as the function display unit, the present invention is not limited thereto. For example, the number of sub dials may be one or more than three. In addition, the function display unit is not limited to a circular planar shape, but may be a rectangular planar shape.

[0072] The sub dial as the function display portion may be configured so that at least its center does not overlap with the pointer shaft 18 (the center portion of the dial 14). Figure 1 , Figure 2 As shown, the entire sub dial as the function display portion may be arranged in a region between the pointer shaft 18 (the center portion of the dial 14 ) and the outer edge of the dial 14 .

[0073] In addition, in this embodiment, an example of analog display is shown by the function needle included in the sub-dial as the function display part, but it is not limited to this, and the function display part can also perform digital display. That is, the function display part can also have a display screen that performs digital display. The display screen can be, for example, a liquid crystal display, an organic EL (ElectroLuminescence: electroluminescence) display, etc.

[0074] In addition, a button 20 as an operating member for the user to perform various operations is arranged on the side surface of the outer shell 10 at the 3 o'clock side. The button 20 receives the user's operation and switches the electrical connection state between the terminal part described later and the control circuit 30. In this embodiment, an example in which three buttons 20 are provided is described. In addition, the electronic clock 100 of this embodiment does not have a crown.

[0075] in addition, Figure 1 , Figure 2 The design of the electronic clock 100 shown is an example. In addition to the case shown here, for example, the outer shape of the outer shell 10 may not be circular, but may be a polygon such as an octagon, or may be a so-called cylindrical shape. The plane shape of the dial 14 including at least the sub-dial as the function display portion may be a shape that has the same outer shape even when rotated in the circumferential direction. In addition, in this embodiment, an example is shown in which the hour hand is set as two hour hands, namely the minute hand 16 and the hour hand 17, but it is not limited to this, and a second hand may also be provided.

[0076] In addition, in the present embodiment, a wristwatch is described as an example of the electronic timepiece 100 , but the present invention is not limited to this, and for example, a pocket watch or the like may also be used.

[0077] The electronic timepiece 100 includes a movement 1 housed in an outer case 10. Figures 3 to 5 , the structure of the movement 1 of this embodiment is described. Figure 3 It is a perspective view showing the movement of this embodiment. Figure 4 yes Figure 3 Exploded perspective view of the movement shown. Figure 5 is a top view showing a portion of the movement of this embodiment. Figure 3 , Figure 4 , Figure 5 , the movement 1 is shown as viewed from the back. Figure 5 In FIG. 1 , the control circuit 30 installed in the circuit block 3 is indicated by a dotted line (see Figure 7 In addition, in the circuit block 3, a large number of electronic components are mounted in addition to the control circuit 30, but Figure 5 In the figure, these electronic components are appropriately omitted.

[0078] The movement 1 is formed by assembling a bottom plate 2, a circuit block 3 and a battery support frame 4 into one body. They are arranged in the order of the bottom plate 2, the circuit block 3 and the battery support frame 4 from the front side to the back side.

[0079] like Figure 3 , Figure 4 As shown, the battery support frame 4 supports the battery 41. The battery 41 may be, for example, a primary battery. However, the present invention is not limited thereto, and the battery 41 may also be a button-type lithium secondary battery.

[0080] Notches 42A to 42G corresponding to the mounting portions 21A to 21G described later are formed on the outer periphery of the battery support frame 4. By forming the notches 42A to 42D in this way, interference between the battery support frame 4 and the switch component 50 mounted on the mounting portion 21 is avoided. In addition, although the description of the reference numerals is omitted, the circuit block 3 is also formed with notches corresponding to the mounting portions 21A to 21G on its outer periphery.

[0081] like Figure 5As shown in FIG. 1 , a vibration motor 60 is assembled on the bottom plate 2. The vibration motor 60 is used to perform the vibration function in the electronic clock 100. The vibration motor 60 can be arranged so as not to overlap the area between the mounting parts 21A to 21G described later and the pointer shaft 18 (the center of the dial 14) of the minute hand 16 and the hour hand 17 when viewed from above. By adopting such an arrangement, space can be saved in the bottom plate 2, and the center of gravity position of the entire electronic clock 100 can be balanced.

[0082] In addition, Figure 5 In the example in which the vibration motor 60 is assembled with a circular plane shape, it can also be Figure 5 A battery, various sensors, etc. may be provided instead of the vibration motor 60 shown.

[0083] In addition, if Figure 5 As shown, a driving mechanism 160 for driving the minute hand 16 , a driving mechanism 170 for driving the hour hand 17 , a driving mechanism 1410 for driving the function hand 141 a , and a driving mechanism 1420 for driving the function hand 142 a are assembled on the bottom plate 2 .

[0084] The driving mechanism 160 includes a driving motor 161 and a gear set 162 for driving the minute hand 16. The driving mechanism 170 includes a driving motor 171 and a gear set 172 for driving the hour hand 17. Figure 5 In the figure, double-coil stepping motors are shown as the driving motors 161 and 171.

[0085] The driving mechanism 1410 includes a driving motor 1411 for driving the function pin 141a and a gear set 1412. The driving mechanism 1420 includes a driving motor 1421 for driving the function pin 142a and a gear set 1422.

[0086] In addition, mounting portions 21A to 21G are formed on the outer periphery of the bottom plate 2 as configuration portions for configuring and mounting the switch component 50. In the present embodiment, an example is shown in which seven mounting portions are formed according to the number of a plurality of terminal portions provided in a circuit block described later. In the present specification, when no special distinction is required, it is simply referred to as "mounting portion 21". In the present embodiment, the switch component 50 described later is mounted on any three mutually adjacent mounting portions among the seven mounting portions 21. In addition, the movement 1 is housed in the outer casing 10 in such a manner that the mounting portion 21 in the middle of the three mounting portions 21 on which the switch component 50 is mounted is at the 3 o'clock position.

[0087] The attachment portions 21A to 21G are arranged at substantially equal intervals in the circumferential direction at intervals corresponding to the arrangement angle of the movement 1 with respect to the outer case 10 .

[0088] In addition, if Figure 5As shown in FIG. 1 , the bottom plate 2 has a convex portion 25 as a positioned portion on its outer periphery. The body 110 of the outer case 10 has a concave portion 15 as a positioning portion on its inner periphery (see the following description). Fig. 9A The positioning portion 15 is provided on at least one of the movement 1 and the outer case 10 , and the positions of the mounting portions 21A to 21G as the arrangement portions are determined by the installation position of the positioning portion 15 .

[0089] The configuration angle of the movement 1 relative to the outer case 10 is determined by the protrusion 25 being inserted into the recess 15. That is, the configuration angle of the movement 1 relative to the outer case 10 can be determined according to the formation position of the recess 15 in the circumferential direction. In other words, the protrusion 25 and the recess 15 function as a stopper for the movement 1 housed in the outer case 10.

[0090] In addition, the recess 15 may be provided in accordance with the number of changes in the appearance of the electronic clock 100, for example, the mounting portions 21A to 21G as the configuration portion. That is, in the present embodiment, five recesses 15 may be formed in the body 110 of the outer case 10. Thus, a common outer case 10 can be used, and the configuration angle of the movement 1 relative to the outer case 10 can be changed according to the appearance of the electronic clock 100. On the other hand, in a structure in which one recess 15 is formed as shown in the figure, there is an advantage that when the electronic clock 100 is repaired, the configuration angle of the movement 1 relative to the outer case 10 will not be mistaken when the movement 1 is temporarily removed from the outer case 10 and reassembled.

[0091] Furthermore, in the present embodiment, an example in which the convex portion is provided on the bottom plate 2 is shown, but the present invention is not limited thereto, and the convex portion may be formed on any member among the members constituting the movement 1 .

[0092] In addition, in this embodiment, an example is shown in which the recess 15 is provided on the body 110 of the outer case 10 and the protrusion 25 is provided on the bottom plate 2, but the present invention is not limited to this. The body 110 of the outer case 10 may also be provided with a protrusion and the bottom plate 2 may be provided with a recess.

[0093] like Figure 4 As shown, the switch component 50 includes a main body 51, a conductive spring 52a and a conductive spring 52b. A switch 51a (see Fig. 6A , Figure 6B ). The conductive spring 52a and the conductive spring 52b are arranged at a distance from each other across the main body 51. When the switch component 50 is mounted on the mounting portion 21, the conductive spring 52a and the conductive spring 52b are connected to the terminals A1 to G2 (see Figure 7) For example, when the switch member 50 is mounted on the mounting portion 21A, the conductive spring 52a is electrically connected to the terminal A1, and the conductive spring 52b is electrically connected to the terminal A2.

[0094] In addition, in this embodiment, only three switch members 50 are provided according to the number of buttons 20, but the present invention is not limited thereto. For example, the switch members 50 may be installed in all of the installation portions 21A to 21G. In this case, the switch members other than the switch members provided corresponding to the buttons 20 are not used to perform the functions of the electronic clock 100.

[0095] Here, refer to Fig. 6A , Figure 6B , the details of the structure of the button 20 and the switch component 50 and their operation are described. Fig. 6A , Figure 6B is a side view schematically showing a button and a switch component. Fig. 6A Indicates the state before the button is pressed by the user. Figure 6B Indicates the state in which the button portion is pressed by the user.

[0096] The button 20 includes a button portion 20a, a housing 20b, and a pressing portion 20c. The button portion 20a and the pressing portion 20c are fixed to each other. The button portion 20a and the pressing portion 20c are provided to be relatively movable with respect to the housing 20b.

[0097] like Figure 6B As shown in FIG. 1 , when the user presses the button portion 20a, the button portion 20a enters the inner side of the housing 20b. Then, the switch 51a of the switch member 50 is pressed by the pressing portion 20c. In this state, the wiring W (described later) connecting the control circuit 30 and GND is Figure 7 The wiring W2 shown in the figure is energized, and a switch signal is input to the control circuit 30. Among them, GND can be a metal outer casing 10 or the like.

[0098] The control circuit 30 performs various functions based on the input switch signal. For example, the control circuit 30 drives the drive mechanisms 160, 170, 1410, and 1420 based on the input switch signal.

[0099] In addition, the button portion 20a may be mounted on the housing 20b via a spring or the like not shown in the figure, and as the user's finger moves away from the button portion 20a, the button portion 20a moves from the housing 20b due to the elastic force of the spring. Figure 6B The status shown returns to Fig. 6A Status shown.

[0100] Furthermore, refer to Figure 7 , Figure 8 , the circuit block 3 and the control circuit 30 in this embodiment are described. Figure 7FIG. 1 is a top view showing a circuit block of the present embodiment. Figure 7 , the circuit block 3 is shown as viewed from the front side.

[0101] like Figure 7 As shown, the circuit block 3 is configured by mounting a wiring pattern including terminal portions A to G and a control circuit 30 electrically connected to the terminal portions A to G via the wiring pattern on a substrate 31 .

[0102] In addition, if Figure 7 As shown, the substrate 31 of the circuit block 3 may have a notch 31a formed along the outer periphery of the vibration motor 60 assembled to the base plate 2. This can avoid interference between the circuit block 3 and the vibration motor 60, and can suppress the electronic timepiece 100 from increasing in thickness.

[0103] like Figure 7 As shown, terminal parts A to G each consisting of two terminals are provided in the circuit block 3. Terminal part A consists of terminal A1 and terminal A2, terminal part B consists of terminal B1 and terminal B2, terminal part C consists of terminal C1 and terminal C2, terminal part D consists of terminal D1 and terminal D2, terminal part E consists of terminal E1 and terminal E2, terminal part F consists of terminal F1 and terminal F2, and terminal part G consists of terminal G1 and terminal G2. In addition, terminals A2 to G2 may be terminals connected to GND.

[0104] In addition, if Figure 7 As shown, the control circuit 30 is connected to the terminal A1 to the terminal G1 through the wiring W1 , and is connected to the terminal A2 to the terminal G2 through the wiring W2 .

[0105] The terminals A to G of the circuit block 3 are respectively provided at Figure 5 The positions corresponding to the mounting portions 21A to 21G of the base plate 2 shown in FIG.

[0106] Figure 8 The control circuit 30 controls the various circuits included in the movement 1 and controls at least the movement of the function hands 141a and 142a arranged on the sub-dials 141 and 142 as the function display parts.

[0107] In addition, if Figure 8 As shown, the control circuit 30 includes a first input unit 30a, a second input unit 30b, a third input unit 30c, and a function setting unit 30d.

[0108] Terminal portion A is configured to be electrically connected to the first input portion 30a through wiring WA. Terminal portion B is configured to be electrically connected to the second input portion 30b through wiring WB. Terminal portion C is configured to be electrically connected to the third input portion 30c through wiring WC. Terminal portion D is configured to be electrically connected to the first input portion 30a through wiring WD. Terminal portion E is configured to be electrically connected to the second input portion 30b through wiring WE. Terminal portion F is configured to be electrically connected to the third input portion 30c through wiring WF. Terminal portion G is configured to be electrically connected to the first input portion 30a through wiring WG.

[0109] like Figure 7 , Figure 8 As shown, the wiring WA, the wiring WD, and a part of the wiring WG are shared. Therefore, the potentials of the terminal A1, the terminal D1, and the terminal G1 are shared.

[0110] In addition, the wiring WB and the wiring WE are partially shared, so that the potentials of the terminal B1 and the terminal E1 are shared.

[0111] In addition, the wiring WC and the wiring WF are partially shared, so that the potentials of the terminal C1 and the terminal F1 are shared.

[0112] By adopting such a wiring pattern, a switch signal can be input to the first input portion 30a from the terminal portion A, the terminal portion D, and the terminal portion G. In addition, a switch signal can be input to the second input portion 30b from the terminal portion B and the terminal portion E. In addition, a switch signal can be input to the third input portion 30c from the terminal portion C and the terminal portion F.

[0113] The function setting unit 30d sets the function to be executed when the switch signal is input to the first input unit 30a, the second input unit 30b, and the third input unit 30c. In addition, the function set by the function setting unit 30d can be pre-stored in the manufacturing process of the electronic clock 100. As to which function each switch component 50 is assigned, it can be set by writing the switch information into a non-volatile memory included in the MCU (Memory Control Unit). Thus, the control circuit 30 can accurately determine the function assigned to each switch component 50.

[0114] The functions set by the function setting unit 30d may also be switched by the user. The user may switch the functions by operating an operating member such as the button 20 or by wireless communication using a wireless function such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).

[0115] Specifically, for example, the control circuit 30 can execute function 1 when a switch signal is input to the first input unit 30a, execute function 2 when a switch signal is input to the second input unit 30b, and execute function 3 when a switch signal is input to the third input unit 30c. Function 1, function 2, and function 3 are, for example, receiving actions, charging amount display, etc., and these functions can be indicated by the actions of each hour hand and each function hand.

[0116] In addition, for example, the function setting unit 30d may pre-set a function to be executed when switch signals are input to each input unit at the same time, that is, when a plurality of buttons 20 are pressed at the same time. In addition, the function to be executed when the push button 20 is long pressed may also be pre-set by the function setting unit 30d.

In other words, in the electronic timepiece 100 of the fifth embodiment, the switch member 50 is not mounted on the mounting portions 21A, 21B, 21C, and 21D.

[0148] In the fifth embodiment, the movement 1 is housed in the outer case 10 at an arrangement angle such that the mounting portion 21F of the bottom plate 2 is at the 3 o'clock position.

[0153] In the present embodiment described above, when it is desired to manufacture an electronic timepiece 100 in which the arrangement of the buttons 20 is fixed and the arrangement of the subdials 141 and 142 as the function display parts is different, it is not necessary to manufacture a separate movement 1. That is, the movement 1 is made common, and the electronic timepiece 100 in which the arrangement of the subdials 141 and 142 is different can be manufactured by simply adjusting the arrangement angle of the movement 1 relative to the outer case 10.

[0154] In addition, in the present embodiment, a portion of the wiring electrically connecting the terminal portion corresponding to the mounting portion 21 on which the switch component 50 is mounted and the control circuit 30 is shared with a portion of the wiring electrically connecting the terminal portion corresponding to the mounting portion 21 on which the switch component 50 is not mounted and the control circuit. That is, in the configuration of the button 20, a portion of the wiring extending from the terminal portions that are not used at the same time is made common. By adopting such a structure, the number of wirings can be reduced and the wiring pattern can be prevented from becoming complicated. As a result, the circuit can be prevented from being enlarged. In addition, in the configuration of the button 20, the wiring extending from the terminal portions (for example, terminal portions A, B, and C) that are used at the same time is not shared.

[0155] Next, refer to Fig.14 , Fig.15 , a first variant example of the present embodiment is described.

[0156] In the above-mentioned examples of the present embodiment, the example of accommodating the switch component 50 in three mutually adjacent mounting portions 21 is described, but in the first modified example, the example of accommodating the switch component 50 in three mutually spaced mounting portions 21 is described. Specifically, Fig.14 As shown in FIG. 1 , an example in which the push button 20 is arranged at the 9 o'clock position, the 2 o'clock position, and the 4 o'clock position will be described.

[0157] Fig.14 It is a top view showing an electronic timepiece according to a first modified example of the present embodiment. Fig.15 FIG. 1 is a top view of a circuit block according to a first variation of the present embodiment. Fig.14 In the figure, the dial 14 and the bottom plate 2 are omitted. Fig.14 , the circuit block 3 is visually recognized through the windshield. Fig.14 In the illustration, the hour hand and sub-dial are omitted. Figure 1-13C The same structures as described above are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0158] In the electronic timepiece 200 of the first variant, as Fig.14 As shown, the buttons 20 are arranged near the 9 o'clock position, the 2 o'clock position, and the 4 o'clock position. That is, in the base plate 2, the switch member 50 is mounted on the mounting portion 21 formed at the position corresponding to the 9 o'clock position, the 2 o'clock position, and the 4 o'clock position.

[0159] In the first variant, if Fig.15 As shown, the circuit block 3 is configured by mounting a wiring pattern including terminal portions A to J and a control circuit 30 electrically connected to the terminal portions A to J via the wiring pattern on a substrate 31 .

[0160] In the first modification, due to the arrangement of the button 20, a portion of the wiring connecting the terminal portion corresponding to the mounting portion 21 not used at the same time and the control circuit 30 is also shared. For example, the terminal portion A is not used at the same time as the terminal portion D, so a portion of the wiring is shared.

[0161] In addition, Fig.15 In the example shown, terminal parts A, F, and H are used. In addition, in the structure of the first variant, a structure using terminal parts B, G, and I and a structure using terminal parts C, H, and J can be realized. That is, in the first variant, the movement 1 is set to be shared, and three changes can be realized. Moreover, by using terminal parts adjacent to each other (for example, terminal parts A, B, and C), eight changes can be realized. That is, a total of 11 changes can be realized.

[0162] In the first modification described above, when it is desired to manufacture an electronic clock 200 with a different appearance by fixing the arrangement of the button 20, it is not necessary to manufacture a movement 1 separately. That is, the movement 1 is made common, and only by adjusting the arrangement angle of the movement 1 relative to the outer case 10, it is possible to manufacture an electronic clock 200 with a different appearance. In addition, by making a part of the wiring W common, the number of wirings can be reduced, and the wiring pattern can be prevented from becoming complicated. As a result, it is possible to prevent the circuit from becoming large-scale.

[0163] Next, refer to Fig.16 , a second variant of this embodiment is described. Fig.16 1 is a top view of the middle frame of the second variant of the present embodiment. In the present embodiment described above, the movement 1 is accommodated in the body 110 of the outer case 10, and the movement 1 is positioned relative to the body 110. However, this is not limited to this, and the outer case 10 may also have a middle frame 111 as an intermediate component inside the body 110.

[0164] Since the outer case 10 has the middle frame 111 , the movement 1 can be assembled into the outer case 10 having a larger diameter.

[0165] The shape of the watch body 110 is the same as that shown in this embodiment, and the watch body 110 may have a recess 15 on its inner surface. In addition, the middle frame 111 has a convex portion 111a on its outer periphery, and the configuration angle of the middle frame 111 relative to the watch body 110 can be determined by fitting the convex portion 111a into the recess 15. In other words, the convex portion 111a and the recess 15 can function as a rotation stopper for the middle frame 111 housed in the outer case 10.

[0166] The shape of the bottom plate 2 is the same as that shown in this embodiment, and the middle frame 111 may have a recess 111b on its inner surface. The configuration angle of the bottom plate 2 relative to the middle frame 111 can be determined by embedding the convex portion 25 of the bottom plate 2 into the recess 111b of the middle frame 111. In other words, the convex portion 25 and the recess 111b can function as a stopper for the bottom plate 2 (movement 1) housed in the middle frame 111.

[0167] In addition, if Fig.16 As shown, the middle frame 111 may have a notch 111c on its periphery according to the number of buttons 20. Fig.16 , an example in which the notches 111c are formed at three locations is shown. Fig.16 , the middle frame 111 used when the middle button 20 is located at the 3 o'clock position among the three buttons 20 arranged adjacent to each other as in the present embodiment is shown. The pressing portion 20c of the button 20 presses the switch 51a of the switch member 50 through the notch 111c.

[0168] Next, refer to Fig.17 , another example of the middle frame 111 is described. Fig.17 FIG. 1 is a top view showing another example of a middle frame. Fig.17 In the embodiment, the middle frame 111 has seven notches 111c on its outer circumference. In this case, the body 110 of the outer case 10 may have a number of recesses 15 corresponding to the number of changes in the appearance of the electronic clock 1. Thus, a common body 110 can be used, and the configuration angle of the middle frame 111 relative to the body 110 can be changed. That is, a common body 110 can be used, and the configuration angle of the movement 1 relative to the body 110 can be changed according to the appearance of the electronic clock 100.

[0169] Next, refer to Fig.18 , Fig.19 , a third variant of the present embodiment is described. Fig.18 FIG. 1 is a top view schematically showing the structure of the middle frame and its surroundings in the third variant of the present embodiment. Fig.18 In FIG. 1 , only the outer shape of the bottom plate 2 is indicated by a circular solid line. Fig.19 It is a cross-sectional view showing a cross section of an electronic timepiece according to a third modified example of the present embodiment.

[0170] In the third modification, similar to the second modification, the outer casing 10 has the middle frame 111, and the mounting portion 121 (mounting portions 121A to 121G) is formed on the middle frame 111. That is, in the third modification, the switch component 50 is mounted on the middle frame 111 instead of being mounted on the bottom plate 2. In addition, the mounting portion 121 of the middle frame 111 may have the same structure and function as the mounting portion 21 described in this embodiment.

[0171] like Fig.19 As shown, a timepiece 300 according to the third modified example includes an outer case 10 including a body 110 and an inner frame 111. The inner frame 111 accommodates a bottom plate 2 (movement 1) inside thereof.

[0172] Mounting portions 121A to 121G for mounting the switch component 50 are formed on the outer periphery of the middle frame 111. In the third variant, an example is shown in which seven mounting portions 121 are formed according to the number of the plurality of terminal portions provided on the circuit block 3, similarly to the bottom plate 2 shown in the present embodiment. In the third variant, for example, similarly to the bottom plate 2 shown in the present embodiment, the switch component 50 can be mounted on any three mounting portions adjacent to each other among the seven mounting portions 121. In addition, for example, the middle mounting portion 121 among the three mounting portions 121 for mounting the switch component 50 can be accommodated in the watch body 110 in such a manner that the mounting portion 121 in the middle of the three mounting portions 121 for mounting the switch component 50 is at the 3 o'clock position.

[0173] Next, refer to Fig. 20 , a fourth variant of this embodiment is described. Fig. 20 It is a plan view showing a state where a switch spring is incorporated in a circuit block in a fourth modification.

[0174] In the present embodiment, an example in which the three switch components 50 are separate bodies has been described, but the present invention is not limited thereto, and the plurality of switch components may be physically constituted by one component.

[0175] In the fourth variant, a switch spring 150 is used which has an arc-shaped configuration portion 151 along the outer edge of the circuit block 3 and three leaf springs 152 (switch components) extending from the configuration portion 151. The switch spring 150 can be assembled to the substrate 31 of the movement 1 by fixing it with a fixing member such as a screw. In addition, although not shown in the figure, the circuit block 3 can have a threaded hole formed according to the installation position of the switch spring 150 for fixing the fixing member. By changing the installation position of the configuration portion 151 relative to the circuit block 3, the position of the leaf spring 152 relative to the terminal portion can be changed. Fig. 20 , an example is shown in which one leaf spring 152 is located at the 3 o'clock position, and two leaf springs 152 are arranged side by side from there toward the 12 o'clock position.

[0176] The leaf spring 152 has a function equivalent to that of the switch component 50 described in the present embodiment. That is, when the user presses the button portion 20a of the button 20, the leaf spring 152 is pressed by the pressing portion 20c and contacts the conductive portion on the circuit substrate. In this state, the wiring W connecting the control circuit 30 and GND is energized, and a switch signal is input to the control circuit 30. The conductive portion can use, for example, a side through hole provided on the side of the circuit substrate. In the fourth variant, it is not necessary to form the mounting portion 21 on the base plate 2, so the structure becomes simple.

[0177] Furthermore, in the fourth modification, an example in which the switch spring 150 is incorporated in the circuit block 3 is shown, but the present invention is not limited thereto, and the switch spring 150 may be incorporated in another substrate included in the movement 1 .

[0178] In the fourth modification, an example is described in which the leaf spring 152 as the switch member is physically composed of one member, but the same is true for the button 20. The plurality of buttons 20 are not limited to being separate bodies, but may also be physically composed of one member. In this case, the button may be in an arc shape extending across the plurality of mounting portions 21 or the plurality of leaf springs 152 in the circumferential direction.
