Description

Technical Field

[0001] The present invention relates to an electronic device and an electronic clock. Background Art

[0002] Conventionally, electronic equipment such as electronic watches that include a solar panel (solar cell) that generates electricity by receiving light is known (for example, refer to Japanese Patent Application Laid-Open No. 2002-350567).

[0003] In such electronic devices, it is necessary to ensure that the solar panel can ensure a sufficient amount of light while studying the arrangement relationship with other components constituting the electronic device, such as a date wheel and a dial.

[0004] In addition, the solar panel must be in contact with the circuit board, but at this time, if the solar panel contacts and interferes with surrounding components, it will also cause damage or failure between components. Therefore, it is preferred to stop the solar panel at a predetermined position. Summary of the invention

[0005] Technical issues

[0006] On the other hand, there is a demand to install solar panels of different shapes and positions depending on the model, in order to meet the needs of the appearance design of electronic devices such as electronic watches and the power generation required in the electronic devices.

[0007] If the shape or arrangement position of the solar panel is different, the locking position and height will also be different, making it difficult to lock with the same locking structure.

[0008] However, if a different module is prepared for each solar panel, the manufacturing cost will increase, which is not preferable. Therefore, there is a demand to cope with various solar panels while reducing the cost by making the components as common as possible.

[0009] The present disclosure has been made in view of the above circumstances, and an object of the present disclosure is to provide an electronic device and an electronic timepiece that can arrange a plurality of types of solar panels at appropriate positions while realizing commonality of components.

[0010] Technical Solution

[0011] In order to solve the above-mentioned problems, the electronic device disclosed in the present invention is characterized by comprising:

[0012] A base having a base mounting portion whose main surface is set in an annular shape, and an outer peripheral side mounting portion provided around the base mounting portion, wherein the height of the outer peripheral side mounting portion is set higher than the height of the base mounting portion;

[0013] an outer peripheral frame arranged along at least a portion of the outer peripheral side mounting portion of the base; and

[0014] The pressing member is inserted through the base in the thickness direction, with the end portion on the insertion side facing the outer peripheral frame and applying a restoring force upward.

[0015] When a ring-shaped solar panel is arranged on the base mounting portion, the pressing member indirectly presses the ring-shaped solar panel toward the outer peripheral frame.

[0016] When at least a portion of a circular solar panel is disposed on the outer peripheral placement portion, the pressing member directly presses the circular solar panel toward the outer peripheral frame.

[0017] Effects of the Invention

[0018] According to the present disclosure, it is possible to arrange a plurality of types of solar panels at appropriate positions while achieving commonality of components. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Refer to the following Figures 1 to 15 Embodiments of the electronic device and the electronic timepiece of the present disclosure will be described.

[0035] In addition, in the embodiments described below, various limitations that are technically preferred for implementing the present disclosure are made, but the scope of the present disclosure is not intended to be limited to the following embodiments and illustrations.

[0036] In the present embodiment, a case where the electronic device is an electronic timepiece that displays time (hereinafter simply referred to as a “timepiece”) will be described as an example.

[0037] The timepiece as an electronic device in the embodiment includes at least a base 2 , an outer peripheral frame 6 , a date wheel 3 , etc., and space for installing a solar panel 5 is ensured above and below the date wheel 3 .

[0038] This makes it possible to cope with a plurality of types of solar panels 5 having different shapes or arrangement positions while using the common base 2 and outer peripheral frame 6 and the like.

[0039] That is, in an embodiment, when a style in which the solar panel 5 is arranged above the date wheel 3 (referred to as a "first style" clock 100) and a style in which the solar panel 5 is arranged below the date wheel 3 (referred to as a "second style" clock 200) are implemented, at least the base 2 and the peripheral frame 6 can be shared.

[0040] In either the case of the "first style" watch 100 or the "second style" watch 200, various components constituting the watch 100 or 200, such as the circuit board 1, the base 2, the date wheel 3, the solar panel 5, and the peripheral frame 6, are housed in a device housing (not shown) in a state of being assembled as a module. The device housing is formed of, for example, a metal such as stainless steel or titanium, or ceramics, various synthetic resins, and the like. In addition, the material forming the device housing is not limited to the materials exemplified here.

[0041] The device housing is formed in a hollow short column shape. The surface side (the visible side in the watch) of the clock 100, 200 in the device housing is closed by a windshield member (not shown) formed of transparent resin or glass. In addition, the back side of the clock 100, 200 in the device housing is closed by a back cover (not shown).

[0042] A strap (not shown) is mounted on the device housing so that the timepiece 100 or 200 can be worn on the user's wrist.

[0043] The specific shape, structure, etc. of the device case forming the appearance of the timepieces 100 and 200 are not particularly limited and can be appropriately set according to the design or specifications.

[0044] In the drawings showing the embodiments, illustration of the device case in the timepieces 100 and 200 is omitted, and only the internal structure (also referred to as a module) accommodated in the hollow portion of the device case is shown.

[0050] like Figures 4 to 6 As shown, the “second model” timepiece 200 includes a substantially annular solar panel 52 as the solar panel 5 .

[0051] In addition, in the following embodiments, together with the "first style" and "second style", Figure 1 , Figure 2 as well as Figure 4 , Figure 5 In the middle, the axial L is called (refer to Figure 1 , Figure 2 as well as Figure 4 , Figure 5 ) is called the "surface side (visible side)", and the lower side is called the "back side (non-visible side)". The "axial direction L" is the direction along the pointer axis in the analog clock (in Figure 2 and Figure 5 etc., the direction of the “pointer axis 25”).

[0052] In addition, hereinafter, the side facing the side of the device housing (not shown) is referred to as the "outer side" or the "outer peripheral side", and the pointer shaft 25 (see Figure 2 and Figure 5 The center side of the timepiece 100, 200 (such as ) is referred to as the “inner side” or the “inner circumference side”.

[0053] [structure]

[0054] First, refer to Figures 1 to 3 The “first model” timepiece 100 (internal structure (module) of the timepiece 100 ) will be described.

[0055] like Figure 1 As shown, the "first style" watch 100 (the internal structure (module) of the watch 100) is provided with a circuit board 1, a base 2, a solar panel 5 (a roughly circular solar panel 51), a peripheral frame 6, a dial 7, etc. along the axial direction L, in the order from the back side (lower side) toward the surface side (upper side) of the watch 100.

[0056] The circuit board 1 is mounted with, for example, an antenna 11 and a secondary battery 12 (see Figure 2 ), and various electronic components such as IC (integrated circuit) chips and terminals (not shown). In addition, a terminal portion 13 on the circuit board 1 side is provided at a position corresponding to a terminal portion 55 of a solar panel 5 described later.

[0057] The base 2 is formed of, for example, various resins, and is a component (main board) used as a base for assembling various components constituting the timepiece 100 (modules of the timepiece 100). Figure 1 As shown in FIGS. 1 and 1B , the base 2 is arranged to overlap the circuit board 1 (on the front side).

[0058] On the base 2, various structural parts for transmitting the motor (not shown) or the power of the motor to the pointer (not shown) or the wheel train mechanism of the date wheel 3 (not shown) are appropriately dispersed and assembled on the surface and back (the visible side and the invisible side in the clock). In addition, a crown (not shown) is provided as an operating part on the side of the clock 100 such as the 3 o'clock side, and a winding core 26 (see FIG. 2 ) connected to the internal structural part (not shown) is installed on the side of the base 2 and at a position corresponding to the crown. Fig. 9 and Fig.10 ).

[0059] Furthermore, as described later, a date wheel 3 (on the surface side) is provided on the base 2. Figure 1 Among them, the first date wheel 31) and the date wheel pressing member 4, etc.

[0060] Figure 7 is a perspective view of the base according to this embodiment. Figure 8 yes Figure 7 An enlarged perspective view of the main parts of the abutment is shown.

[0061] like Figure 7 As shown, the base 2 is formed of resin or the like in a generally disk-like shape as a whole, and a shaft hole 24 is provided in the center portion for inserting the pointer shaft 25. The base 2 includes a first mounting portion 21 as a base mounting portion provided with a main surface 21a in a generally annular shape, a second mounting portion 22 provided on the inner side of the first mounting portion 21, and an outer peripheral side mounting portion (third mounting portion) 23 provided around the first mounting portion 21.

[0062] Here, the "main surface" refers to a surface used as a reference in the first carrier portion 21, etc. For example, in the first carrier portion 21, there is a portion that is hollowed out and becomes lower or a portion that protrudes on the contrary, and the whole has projections and depressions. In this case, similarly, when the flat-plate-shaped component is placed on the first carrier portion 21, the surface that mainly supports the mounted component is called the "main surface 21a" in the first carrier portion 21. The same applies to the "main surfaces" of the second carrier portion 22 and the peripheral side carrier portion 23 (that is, the "main surface 22a" of the second carrier portion 22 and the "main surface 23a" of the peripheral side carrier portion 23). In addition, the main surface 23a of the peripheral side carrier portion 23, which serves as the third carrier portion, is set to include a substantially arc-shaped surface.

[0063] In the embodiment, the main surface 22 a of the second mounting portion 22 of the base 2 is lower in height (height in the axial direction L) than the main surface 23 a of the outer circumferential mounting portion 23 and higher in height than the main surface 21 a of the first mounting portion 21 .

[0064] exist Figure 7 and Figure 8 In FIG. 1 , the main surface 21a of the first mounting portion 21 is shown in gray shadow. Figure 7 and Figure 8 (especially Figure 8 ), the main surface 21a of the first mounting portion 21 which is arranged in a substantially annular shape is one step lower than the main surface 22a of the second mounting portion 22 which is arranged on the inner side compared to the first mounting portion 21.

[0065] In addition, if Figure 7 and Figure 8 As shown in FIG. 1 , a protrusion 221 having a height higher than the main surface 22a of the second mounting portion 22 is provided at the boundary portion between the second mounting portion 22 and the first mounting portion 21. The protrusion 221 is an inner peripheral side (inner peripheral portion 313, see FIG. 1 ) of the date wheel 3 (first date wheel 31) described later for placement. Fig. 9 ), the upper surface of the protrusion 221 is configured to include a substantially arc-shaped surface. In other words, the protrusion 221 in the embodiment is partially and discontinuously configured in an arc shape. In addition, the protrusion 221 can be almost continuously configured in a ring shape at the boundary portion between the first carrier portion 21 and the second carrier portion 22. In addition, the entire second carrier portion 22 (the main surface 22a of the second carrier portion 22) can be formed to have the same height as the protrusion 221. The protrusion 221 supports the inner circumference of the date wheel 3 (the first date wheel 31) in a well-balanced manner at almost equal intervals, so that the date wheel 3 (the first date wheel 31) is arranged on the second carrier portion 22 without tilting.

[0066] Furthermore, the protrusion 221 is not necessarily provided on the second mounting portion 22 , and may be provided on the first mounting portion 21 as long as it is provided at a position corresponding to the outer periphery (boundary) of the substantially circular second mounting portion 22 .

[0067] In addition, the roughly circular date wheel pressing member 4 must press the inner circumference of the roughly annular date wheel 3. Therefore, the second carrier 22 on which the date wheel pressing member 4 and other components are placed is preferably roughly circular, and the protrusion 221 is preferably provided on the outer circumference of the second carrier 22 (the boundary with the first carrier 21) in terms of both configuration and ease of processing. However, when the protrusion 221 cannot be provided on the second carrier 22 or near the second carrier 22 due to the configuration of various components such as a motor not shown, as shown in FIG. Figure 7As shown, an auxiliary protrusion 211 having an upper surface may be provided in the first receiving portion 21 at the same height as the upper surface of the protrusion 221 .

[0068] Fig. 9 It is shown Figure 7 The figure is a perspective view showing a state where a first date indicator and a date indicator pusher are assembled on the upper surface (front side) of the base.

[0069] like Fig. 9 As shown, the date wheel 3 (first date wheel 31) is formed in a substantially annular shape and is arranged below the outer peripheral frame 6. In addition, as described above, at least a portion of the inner peripheral side (inner peripheral portion 313) of the date wheel 3 (first date wheel 31) is arranged on the second mounting portion 22 (in the embodiment, the protruding portion 221 of the second mounting portion 22). The material forming the date wheel 3 (first date wheel 31) is not particularly limited, but can be formed of metal such as stainless steel (SUS) or titanium, for example.

[0070] The date wheel 3 (first date wheel 31) has a roughly annular main body 311 and an inner circumference 313 as a portion of the inner circumference of the main body 311. The surface of the main body 311 is provided with numbers indicating the date (referred to as a character portion 312). The character portion 312 may be provided in a planar manner by printing or the like, or may be provided in a three-dimensional manner by cutting or pasting a cut character shape onto the main body 331. In addition, a tooth portion 35 (gear portion) is formed along the circumferential direction on the inner circumference of the inner circumference 313 (refer to Fig. 9 ).

[0071] At least a gear 27 meshing with the toothed portion (gear portion) 35 of the date wheel 3 (first date wheel 31) is exposed on the main surface 22a of the second mounting portion 22. The gear 27 constitutes a gear train mechanism (not shown) that rotates the roughly annular date wheel 3 (first date wheel 31) in the circumferential direction. In addition, the main body of the gear train mechanism that rotates the date wheel 3 (first date wheel 31) or a motor for operating it (both not shown) can be assembled on the back side of the base 2.

[0072] In addition, a date wheel pressing member 4 for suppressing the floating of the date wheel 3 (first date wheel 31) is arranged on the main surface 22a of the second mounting portion 22. The date wheel pressing member 4 is a roughly disc-shaped member arranged on the inner side (inner side of the protrusion 221 of at least a part of the inner circumference of the date wheel 3 (first date wheel 31)) of the roughly annular date wheel 3 (first date wheel 31) for mounting. The date wheel pressing member 4 has a top plate portion 41 extending above at least a part of the inner circumference of the date wheel 3. It is arranged to cover the upper part of the inner circumference of the date wheel 3 (first date wheel 31) to such an extent that it does not interfere with the tooth portion (gear portion) 35 of the date wheel 3 (first date wheel 31). Thus, the date wheel pressing member 4 suppresses the floating of the date wheel 3 (first date wheel 31) and prevents its rotation.

[0073] Furthermore, a non-illustrated antimagnetic plate or the like may be disposed on the main surface 22a of the second mounting portion 22. When the antimagnetic plate is provided, it is disposed at a position that can at least cover the motor, and the antimagnetic plate is configured to magnetically shield the motor.

[0074] Furthermore, the outer peripheral side mounting portion 23 of the base 2 can be provided with at least a portion of the solar panel 5 (substantially circular solar panel 51) disposed at a height position between the outer peripheral frame 6 and the date wheel 3 (first date wheel 31). Figures 1 to 3 As shown, in the “first model” timepiece 100 , the solar panel 5 (substantially circular solar panel 51 ) is arranged in a space above the date indicator 3 (first date indicator 31 ).

[0075] The solar panel 5 includes one or more photovoltaic elements that receive light and generate electromotive force.

[0076] Fig.10 It is shown in Fig. 9 The illustrated state is a perspective view of a state in which a substantially circular solar panel is placed on the upper surface (front side) of the base.

[0077] like Figure 1 and Fig.10 As shown, the substantially circular solar panel 51 provided in the “first style” timepiece 100 is a relatively thin disk-shaped component, which is provided in the axial hole 24 (refer to Figure 7 ) is formed at a substantially central portion thereof with an axial hole 511 through which the pointer shaft 25 is inserted.

[0078] In addition, a small window 512 is formed at the 3 o'clock position or the like in the analog timepiece, and a character portion 312 of the date wheel 3 (first date wheel 31 ) corresponding to the date display is exposed through the small window 512 .

[0079] In addition, if Fig.10As shown, the substantially circular solar panel 51 has an outer peripheral portion 513 which does not contribute to power generation at its outer peripheral portion, and the outer peripheral portion 513 is placed on the main surface 23a of the outer peripheral side placement portion 23. Figure 1 In the example shown in FIG. 1 , the outer peripheral portion 513 is provided at a portion of the outer peripheral portion of the substantially circular solar panel 51 , but the range, size, shape, etc. of the outer peripheral portion 513 are not limited to the example shown in the figure. The outer peripheral portion 513 may be provided at the entire outer peripheral portion of the substantially circular solar panel 51 , for example.

[0080] An extension portion 515 extending outward is formed on a portion of the outer peripheral portion 513, and a terminal portion 55 is provided on the back side of the extension portion 515. A contact member 15 is connected from below at a position corresponding to the terminal portion 55. The contact member 15 is, for example, a coil spring formed of a conductor, and the end portion on the base end side is connected to the terminal portion 13 on the circuit board 1 side (see Figure 1 ) and is inserted through the base 2 (e.g., the first mounting portion 21 or the outer peripheral mounting portion 23 of the base 2) from the circuit board 1 side in the thickness direction (in the direction of the axial direction L), so that the end portion on the insertion side is connected to the terminal portion 55 of the solar panel 5 (the substantially circular solar panel 51). The number of the terminal portion 13 and the terminal portion 55 is two, respectively, and the solar panel 51 is connected to the circuit board 1 at two locations.

[0081] Thus, the solar panel 5 (roughly circular solar panel 51 ) is electrically connected to the circuit board 1 via the contact member 15 , and the electromotive force generated in the solar panel 5 is supplied to the circuit board 1 or the secondary battery 12 provided on the circuit board 1 , and is used as a power source for various parts of the clock 100 .

[0082] By using a coil spring as the contact member 15 , even when the length of the contact member 15 slightly varies due to tolerance or the like, it is possible to suppress the occurrence of contact failure.

[0083] On the other hand, the contact member 15 as a coil spring functions as a pressing member that applies a restoring force upward from the circuit board 1 at the end portion on the insertion side. That is, the contact member 15 has a pressing force that pushes the solar panel 5 upward.

[0084] Therefore, in the embodiment, the outer peripheral frame 6 is arranged at a position facing the end portion of the contact member 15 on the insertion side to prevent the solar panel 5 from being pushed upward by the contact member 15 .

[0085] The outer peripheral frame 6 resists the pressing force from below of the contact member 15 as the pressing member and presses at least a part of the solar panel 5 from above, thereby preventing the solar panel 5 from floating or shaking.

[0086] That is, when at least a portion of the substantially circular solar panel 51 is disposed on the outer peripheral mounting portion 23 , the outer peripheral frame 6 presses at least a portion of the substantially circular solar panel 51 from above to prevent the solar panel 5 (substantially circular solar panel 51 ) from floating.

[0087] Fig.11 This is a perspective view of the outer frame viewed from the back side facing the base. Fig.12 It is shown in Fig.11 A perspective view showing a state where a substantially circular solar panel is superimposed on an outer peripheral frame from the back side.

[0088] like Fig.11 As shown in FIGS. 1 and 10 , the outer peripheral frame 6 is formed in a substantially annular shape and is arranged along at least a portion of the outer peripheral side mounting portion 23 in the base 2 .

[0089] The outer peripheral frame 6 has hooks 65 at multiple positions in the circumferential direction that are locked to the outer peripheral portion of the base 2. The hooks 65 have, for example, spring characteristics and have locking claws 651 that protrude toward the inner peripheral side. By hooking the locking claws 651 of the hooks 65 to the outer peripheral portion of the base 2, the outer peripheral frame 6 is locked to the base 2 and is installed so as not to float from the base 2.

[0090] In addition, the hook portion 65 is preferably provided near the position where the contact member 15 is provided when at least the solar panel 5 (the substantially circular solar panel 51) is arranged. As described above, the contact member 15 is a pressing member such as a coil spring, and the solar panel 5 (the substantially circular solar panel 51) is pushed up from below at the portion where the contact member 15 is provided. Therefore, by providing the hook portion 65 near this portion, the outer peripheral frame 6 is firmly locked to the base 2, and the pressing force from below when the solar panel 5 is pushed up can be resisted.

[0091] In the "second embodiment" described later, the spacer 8 is disposed at a position substantially facing the contact member 15. Therefore, a hole 63 for attaching the spacer 8 is formed in the outer peripheral frame 6. The hook 65 is preferably provided near the hole 63.

[0092] The outer peripheral frame 6 has a first lower surface 61 provided at a lower portion of the outer peripheral side, and a second lower surface 62 located on the inner peripheral side than the first lower surface 61 and provided above at least a portion of the first lower surface 61 .

[0093] The first lower surface 61 of the outer peripheral frame 6 is in contact with the main surface 23 a of the outer peripheral side mounting portion 23 (see, for example, FIG. 3 ).

[0094] In addition, the peripheral frame 6 is configured to be able to install the gasket 8 described later. For example, the gasket 8 is formed of a material such as metal or carbon tool steel, and the peripheral frame 6 is formed of a synthetic resin (insulating material) or the like. For example, a hole portion 63 for locking at least a portion of the gasket 8 is provided on the second lower surface 62 of the peripheral frame 6. The gasket 8 is arranged at a position that is at least approximately opposite to the contact member 15 serving as a pressing member. In addition, the gasket 8 can be provided not only at a position that is approximately opposite to the contact member 15, but also at multiple positions in the circumferential direction of the peripheral frame 6. In this case, it is preferred that the gasket 8 is arranged as evenly spaced as possible in the circumferential direction in addition to the position that is approximately opposite to the contact member 15.

[0095] When the solar panel 5 (substantially circular solar panel 51) is arranged in a space above the date wheel 3 (first date wheel 31) as in the watch 100, Fig.12 As shown, at least a portion of the outer peripheral portion 513 of the solar panel 5 (substantially circular solar panel 51) is arranged to be in contact with the second lower surface 62. In addition, at least a portion of the outer peripheral portion 513 of the substantially circular solar panel 51 may be sandwiched between the second lower surface 62 of the outer peripheral frame 6 and the outer peripheral side mounting portion 23.

[0096] Fig.13 It is a side cross-sectional view of the main part of the contact portion between the solar panel and the circuit board in the "first model" timepiece provided with a substantially circular solar panel.

[0097] like Fig.13 As shown, when a substantially circular solar panel is arranged in a space above the date wheel 3 (first date wheel 31 ), the peripheral frame 6 can directly press the peripheral portion 513 of the solar panel 5 (substantially circular solar panel 51 ) through the second lower surface 62 .

[0098] Thus, even if the solar panel 5 (substantially circular solar panel 51) is pushed up from the bottom by the restoring force (pressing force) of the contact member 15, the solar panel 5 is prevented from floating up and is kept in a non-inclined state.

[0099] The dial 7 (first dial 71) is mounted on the base 2 after the date wheel 3 (first date wheel 31), the date wheel pressing member 4, and the solar panel 5 (substantially circular solar panel 51) are assembled. Fig.10 The first dial 71 is overlapped with the first dial 71 on the upper side (surface side) of the axial direction L. The first dial 71 is formed of a light-transmitting material such as a transparent resin that allows sunlight to pass through. As a result, the solar panel 5 (roughly circular solar panel 51) arranged below the first dial 71 can receive sunlight, and a sufficient amount of light required for power generation can be ensured.

[0100] A shaft hole 711 is formed in the substantially central portion of the dial 7 (first dial 71) corresponding to the position through which the pointer shaft 25 is inserted. The pointer shaft 25 is inserted through the shaft hole 711 from the bottom to the top in the axial direction L, and is exposed on the dial 7 (first dial 71). Pointers (not shown) such as the hour hand, minute hand, and second hand are mounted on the portion of the pointer shaft 25 that is exposed above the dial, and the time is appropriately displayed.

[0101] In addition, in the dial 7 (first dial 71), a date window 712 is formed at a position corresponding to the small window 512 in the solar panel 5 (substantially circular solar panel 51) (see Figure 1 ). From the date window 712, a character portion 312 corresponding to the date display of the date wheel 3 (first date wheel 31) exposed through the small window 512 can be seen (refer to Fig. 9 ).

[0102] Next, refer to Figures 4 to 6 The second type of watch 200 (internal structure (module) of the watch 200) is described. Figure 6 The display of the dial 7 is omitted. In addition, the same reference numerals are used for the same components or parts as those in the aforementioned "first style", and the description thereof is appropriately omitted.

[0103] like Figure 4 As shown, the "second style" watch 200 (the internal structure (module) of the watch 200) includes a circuit board 1, a base 2, a solar panel 5 (roughly annular solar panel 52), a peripheral frame 6, a dial 7, etc. in the order from the back side (lower side) toward the surface side (upper side) of the watch 200 along the axial direction L.

[0104] In the timepiece 200, the circuit board 1, the base 2, and the peripheral frame 6 are constructed in the same manner as in the embodiment of the present invention. Figures 1 to 3 The timepiece 100 of the “first model” shown in the figures (internal structure (module) of the timepiece 100 ) is the same as that shown in the figures, and thus the description thereof is omitted.

[0105] A date wheel 3 is provided above the base 2 (on the surface side). Figure 4 Among them, the second date wheel 32) and the date wheel pressing member 4, etc.

[0106] like Figure 4 As shown in FIGS. 1 and 2 , the second date indicator 32 is formed in a substantially annular shape similarly to the first date indicator 31 , and is arranged below the outer frame 6 .

[0107] The date wheel 3 (second date wheel 32) includes an outer circumference 321 as an outer circumference, an inner circumference 322 as an inner circumference, and a character portion 323 provided between the outer circumference 321 and the inner circumference 322. In addition, between the outer circumference 321 and the inner circumference 322 are the character portion 323 and a through portion 324 that penetrates the front and back surfaces of the date wheel 3, leaving a minimum portion for connecting the character portion 323 to the outer circumference 321 or the inner circumference 322.

[0108] At least a part of the inner circumference 322 of the date indicator 3 (the second date indicator 32 ) is arranged on the second mounting portion 22 (in the embodiment, the protruding portion 221 of the second mounting portion 22 ).

[0109] On the inner circumferential side of the inner circumferential portion 322, similarly to the first date indicator 31, a tooth portion 35 (gear portion) meshing with the gear 27 constituting the train mechanism is formed along the circumferential direction (see Figure 6 ).

[0110] The material forming the date wheel 3 (second date wheel 32) is not particularly limited, but is formed of metals such as stainless steel (SUS) or titanium. In addition, the method of forming the character portion 323 is not particularly limited, and various methods such as laser processing, perforation processing of perforating a metal plate, and casting can be used.

[0111] In addition, since the date indicator pusher 4 is the same as that of the “first model” timepiece 100 , the description thereof will be omitted.

[0112] In the "second style" watch 200, the solar panel 5 is as shown in FIG. Figure 4 The solar panel 52 is a substantially annular solar panel. The solar panel 5 (substantially annular solar panel 52) is disposed on the first mounting portion 21 of the base 2. The first mounting portion 21 is provided corresponding to the lower position of the date wheel 3 (second date wheel 32).

[0113] The substantially annular solar panel 52 is disposed below the date wheel 3 (second date wheel 32), and as described above, a through portion 324 is formed in the second date wheel 32. Therefore, sunlight passes through the through portion 324 and irradiates the solar panel 5 (substantially annular solar panel 52), thereby ensuring sufficient light required for power generation.

[0114] In addition, the main surface 21a of the first mounting portion 21 of the base 2 is located at a lower height position than the date wheel 3 (second date wheel 32), and a substantially annular solar panel 52 can be arranged. The height dimension from the main surface 21a of the first mounting portion 21 in the base 2 to the lower surface of the date wheel 3 (second date wheel 32) is greater than the thickness dimension of the substantially annular solar panel 52.

[0115] Therefore, even when the solar panel 5 (substantially annular solar panel 52 ) is disposed on the first mounting portion 21 , the substantially annular solar panel 52 does not interfere with the lower surface of the second date indicator 32 , and the rotation of the date indicator 3 (second date indicator 32 ) is not hindered.

[0116] An extension portion 522 extending toward the outer circumference is provided on the outer circumference 523 of the solar panel 5 (the substantially annular solar panel 52) and does not contribute to power generation, and a terminal portion 55 is provided on a portion of the back side of the extension portion 522, similar to the substantially circular solar panel 51 in the “first style”. The contact member 15 is connected from below at a position corresponding to the terminal portion 55. The contact member 15 functions as a pressing member that applies a restoring force upward from the side of the circuit board 1 disposed below the base 2.

[0117] like Figure 5 , Figure 6 As shown, when the solar panel 5 (substantially annular solar panel 52) is arranged on the first mounting portion 21 (main surface 21a of the first mounting portion 21) of the base 2 which is the space below the date wheel 3 (second date wheel 32), there is a distance between the second lower surface 62 of the peripheral frame 6 and the upper surface of the solar panel 5 (substantially annular solar panel 52). Therefore, even if the solar panel 5 is pushed up by the contact member 15, the outer peripheral portion 523 of the solar panel cannot be directly pressed by the second lower surface 62 of the peripheral frame 6.

[0118] Therefore, when the solar panel 5 (substantially annular solar panel 52 ) is arranged on the first mounting portion 21 (the main surface 21 a of the first mounting portion 21 ), the spacer 8 is mounted in the hole 63 provided on the second lower surface 62 of the outer peripheral frame 6 .

[0119] Figure 6 is a cross-sectional perspective view of the main parts of the watch showing a state where a gasket is installed in the hole portion, Fig.14 yes Figure 6 This is a side sectional view of the main parts of the timepiece in the state shown.

[0120] like Figure 6 and Fig.14As shown, the gasket 8 is installed at a position substantially opposite to the contact member 15 as a pressing member, and the peripheral frame 6 indirectly presses at least a portion (e.g., the extension portion 522 or the peripheral portion 521) of the solar panel 5 (roughly annular solar panel 52) from above via the gasket 8 when the gasket 8 is installed on the second lower surface 62 of the peripheral frame 6. As a result, the pressing force from below by the contact member 15 as a pressing member can be resisted, so that the solar panel 5 (roughly annular solar panel 52) can be pressed, and the solar panel 5 (roughly annular solar panel 52) can be prevented from floating up, and can be reliably connected to the terminal portion 13 on the side of the circuit board 1. In addition, it is also possible to avoid the solar panel 5 (roughly annular solar panel 52) arranged below the date wheel 3 (second date wheel 32) from being in contact with the lower surface of the date wheel 3 (second date wheel 32), etc., which hinders the rotation of the date wheel 3.

[0121] The dial 7 (second dial 72 ) is arranged on the upper side (surface side) in the axial direction L in an overlapping manner from above after the date wheel 3 (second date wheel 32 ), the date wheel pusher 4 , and the solar panel 5 (substantially annular solar panel 52 ) are assembled on the base 2 .

[0122] The dial plate 7 (second dial plate 72) is formed of, for example, a metal material such as titanium or stainless steel (SUS), or various resins, etc. The second dial plate 72 is a non-light-transmitting, non-transparent member that does not allow light to pass therethrough.

[0123] like Figure 4 As shown, the dial 7 (second dial 72) is a substantially disc-shaped member, and includes: a main body 722, in which a shaft hole 721 is formed in a substantially central portion for inserting the pointer shaft 25; and an outer peripheral portion 724, which is formed on the outer periphery of the main body 722 and is provided with a plurality of openings 723 arranged in the circumferential direction. In the second dial 72, at least the portion corresponding to the date wheel 3 (second date wheel 32) is the outer peripheral portion 722, and the character portion 323 of the date wheel 3 (second date wheel 32) is visibly exposed through the openings 723. In addition, the second dial 72 allows sunlight to be transmitted through the openings 723 to the solar panel 5 (substantially annular solar panel 52) arranged below the date wheel 3 (second date wheel 32).

[0124] In addition, in the second dial plate 72 , at least the outer peripheral portion 722 may be formed of a light-transmitting material such as a transparent resin that transmits sunlight. In this case, the outer peripheral portion 722 may be provided with an opening 723 .

[0125] [effect]

[0126] Next, the operation of this embodiment will be described.

[0127] In this embodiment, a base 2 is arranged on the circuit board 1, the inner circumference 313, 322 of the date wheel 3 (the first date wheel 31 or the second date wheel 32) is arranged on the protrusion 221 of the second loading portion 22 of the base 2, and the date wheel pressing member 4 is arranged on the inner side of the date wheel 3 (the first date wheel 31 or the second date wheel 32).

[0128] When the timepiece is the “first model” timepiece 100 , the substantially circular solar panel 51 is disposed in a space above the date indicator 3 (first date indicator 31 ).

[0129] That is, at least a portion of the outer peripheral portion 513 of the substantially circular solar panel 51 is disposed on the main surface 23a of the outer peripheral mounting portion 23 of the base 2, and the outer peripheral frame 6 or the dial 7 (first dial 71) is disposed thereon.

[0130] While at least a portion of the first lower surface 61 of the outer peripheral frame 6 contacts the main surface 23a of the outer peripheral side mounting portion 23, at least a portion of the second lower surface 62 of the outer peripheral frame 6 contacts the upper surface of at least a portion of the outer peripheral portion 513 of the substantially circular solar panel 51.

[0131] Thus, at least a portion of the outer peripheral portion 513 of the roughly circular solar panel 51 is sandwiched between the main surface 23a of the peripheral side mounting portion 23 of the base 2 and the second lower surface 62 of the peripheral frame 6, and is directly pressed by the second lower surface 62 of the peripheral frame 6 in a manner that the roughly circular solar panel 51 will not float up even when the roughly circular solar panel 51 is pressed from the bottom by the contact part 15.

[0132] When the timepiece is the “second model” timepiece 200 , the substantially annular solar panel 52 is disposed on the main surface 21 a of the first mounting portion 21 of the base 2 which is a space below the date indicator 3 (second date indicator 32 ).

[0133] In this case, the date indicator 3 (second date indicator 32 ), the outer frame 6 , and the dial 7 (second dial 72 ) are arranged from above the substantially annular solar panel 52 .

[0134] At this time, the gasket 8 is mounted on the hole portion 63 formed on the second lower surface of the outer peripheral frame 6, and the outer peripheral frame 6 is mounted on the base 2 in this state. In this case as well, at least a portion of the first lower surface 61 of the outer peripheral frame 6 is in contact with the main surface 23a of the outer peripheral side mounting portion 23. In addition, the gasket 8 provided on the second lower surface 62 of the outer peripheral frame 6 is in contact with at least a portion of the outer peripheral portion 523 of the substantially annular solar panel 52, and presses the substantially annular solar panel 52 against the main surface 21a of the first mounting portion 21 of the base 2.

[0135] Thus, the outer peripheral frame 6 of the substantially annular solar panel 52 is indirectly pressed via the spacer 8 provided on the second lower surface 62 thereof so as not to float up even when pressed from below by the contact member 15 .

[0136] In the past, electronic watches generally use relatively cheap and roughly circular solar panels with a large light receiving area. In addition, there are also models that use relatively expensive but relatively high power generation efficiency relative to the light receiving area.

[0137] In the past, the base or the peripheral frame corresponded to a configuration or shape of a solar panel. When a solar panel with a different configuration or shape was used, the base or the peripheral frame had to be redesigned and manufactured. In particular, for devices such as clocks, miniaturization or thinning must be ensured in order for users to wear them on their wrists. Furthermore, there is a problem that the configuration freedom of large devices such as solar panels and date wheels is low.

[0138] For example, when a roughly annular date wheel and a roughly circular solar panel are mounted on an electronic watch, the roughly circular solar panel is usually arranged on the roughly annular date wheel. If, on the contrary, the roughly circular solar panel is arranged below the roughly annular date wheel, not only will the date wheel block the light to the solar panel and reduce the power generation efficiency, but the roughly circular solar panel with a larger area (volume) will be arranged further inside the device, thereby reducing the freedom of configuration of other devices.

[0139] In addition, when the substantially annular date wheel and the substantially annular solar panel are mounted on an electronic watch, the substantially annular solar panel can be arranged at either the upper or lower position relative to the substantially annular date wheel. However, if the substantially annular solar panel is arranged above the substantially annular date wheel, a boundary will be formed between the substantially annular solar panel and the area inside it, which may lead to deterioration of the design, such as the user can easily recognize that the substantially annular solar panel is arranged. Therefore, the design is improved by deliberately displaying the substantially annular date wheel. Furthermore, it is more preferable to arrange the substantially annular solar panel below the substantially annular date wheel for reasons such as making the boundary between the substantially annular solar panel and the area inside it inconspicuous in the date wheel.

[0140] Thus, in the past, due to the demand for miniaturization or thinning, as well as the positional relationship with larger devices such as a date wheel, etc., it was necessary to redesign and manufacture the base or the peripheral frame according to the shape of the solar panel.

[0141] For example, Fig.15 This is a side cross-sectional view of a main part showing an example of a conventional timepiece (timepiece module).

[0142] exist Fig.15In the example shown, there is no space for arranging the solar panel 50 below the date wheel 30. In this case, the base 20 and the peripheral frame 60 can only cope with the case where the solar panel 50 is arranged in the space above the date wheel 30 in the timepiece 500 (the module of the timepiece 500) (the "first style" in this embodiment), but cannot cope with the case where the solar panel 50 is arranged in the space below the date wheel 30 (the "second style" in this embodiment).

[0143] exist Fig.15 In the structure shown, the solar panel 50 is arranged almost entirely below the dial 70. Therefore, a light-transmitting type has to be adopted as the dial 70. In addition, since the solar panel 50 is arranged above the date wheel 30, there are restrictions on appearance or design, such as it is difficult to adopt a structure that displays the date wheel 30 as an appearance design.

[0144] In this regard, by adopting the structure of the present embodiment, while at least the base 2 and the peripheral frame 6 are shared, a solar panel 5 (a roughly circular solar panel 51 or a roughly annular solar panel 52) can be selectively arranged at either the top or the bottom of the date wheel 3 (the first date wheel 31 or the second date wheel 32) according to the design, etc.

[0145] [Effect]

[0146] As described above, according to the present embodiment, the timepiece 100, 200 as an electronic device comprises: a base 2 having a first mounting portion 21 as a base mounting portion whose main surface 21a is set to be roughly annular, and an outer peripheral side mounting portion 23 arranged around the first mounting portion 21, and the height of the outer peripheral side mounting portion 23 is set to be higher than the height of the first mounting portion 21; an outer peripheral frame 6, which is arranged along at least a portion of the outer peripheral side mounting portion 23 in the base 2; and a contact member 15, which is inserted through the base 2 in the thickness direction, is a pressing member whose end on the insertion side is opposite to the outer peripheral frame 6, and applies a restoring force upward, when a roughly annular solar panel 52 is arranged on the first mounting portion 21, the contact member 15 indirectly presses the roughly annular solar panel 52 against the outer peripheral frame 6, and when at least a portion of the roughly circular solar panel 51 is arranged on the outer peripheral side mounting portion 23, the contact member 15 directly presses the roughly circular solar panel 51 against the outer peripheral frame 6.

[0147] Thus, the solar panel 5 can be arranged in the space above and below the date wheel 3 , and when arranged at any position, the solar panel 5 can be pressed by the peripheral frame 6 and can resist the pressing force of the contact member 15 .

[0148] Therefore, the solar panel 5 can be held at an appropriate position without requiring time and cost for designing and manufacturing the base 2 and the like for each design and the like.

[0149] In addition, the outer peripheral frame 6 of the present embodiment has a first lower surface 61 which is provided at the lower portion of the outer peripheral side and is in contact with the main surface of the outer peripheral side mounting portion 23, and a second lower surface 62 which is located at the inner peripheral side relative to the first lower surface 61, is provided above at least a portion of the first lower surface 61, and can be mounted with the gasket 8. Thus, the gasket 8 can be received on the second lower surface 62 of the outer peripheral frame 6, and the solar panel 5 can be held in an appropriate position even when either the substantially circular solar panel 51 or the substantially annular solar panel 52 is arranged.

[0150] In addition, according to the contact member 15 as the pressing member in the present embodiment, when the substantially annular solar panel 52 is arranged on the first placement portion 21, the substantially annular solar panel 52 is pressed toward the second lower surface 62 via the gasket 8 in a state where the gasket 8 is mounted on the second lower surface 62 of the outer peripheral frame 6; when at least a portion of the substantially circular solar panel 51 is arranged on the outer peripheral side placement portion 23, the substantially circular solar panel 51 is pressed toward the second lower surface 61. Thus, in the case where either the substantially circular solar panel 51 or the substantially annular solar panel 52 is arranged, the contact member 15 can stably contact the circuit board 1.

[0151] In the present embodiment, the terminal portion 55 of the substantially annular solar panel 52 and the terminal portion 55 of the substantially circular solar panel 51 are each provided at the lower portion of the extension portion 515 extending to the outside of the outer peripheral portion 513 .

[0152] Therefore, by being pressed from below by the contact member 15 as a pressing member, the contact member 15 can reliably come into contact with the terminal portion 55 of the solar panel 5 .

[0153] In addition, in the present embodiment, at least a portion of the outer circumferential placement portion 23 is cut out so that the first placement portion 21 extends outward, and the extension portion 515 extends to the position where the outer circumferential placement portion 23 is cut out.

[0154] Thus, by forming a through hole or the like in the extended portion of the first mounting portion 21 , the terminal portion 13 of the circuit board 1 arranged below the base 2 and the terminal portion 55 of the solar panel 5 can be easily electrically connected via the contact member 15 .

[0155] In the present embodiment, the substantially annular date indicator 3 is provided, and the date indicator 3 is arranged at a height position below the outer circumference side mounting portion 23 and above the main surface 21 a of the first mounting portion 21 .

[0156] Thus, it is possible to ensure space above and below the date indicator 3 for arranging the solar panel 5 (the substantially circular solar panel 51 and the substantially annular solar panel 52 ).

[0157] In addition, a circuit board 1 is arranged below the base 2, and the pressing component is a contact component 15 whose end on the insertion side is connected to the terminal portion 55 of the roughly annular solar panel 52 or the roughly circular solar panel 51, and whose end on the other end side is connected to the terminal portion 13 of the circuit board 1.

[0158] Regardless of the configuration position or shape, the solar panel 5 must be electrically connected to the circuit board 1. Even if there is a deviation due to tolerance, the contact member 15 often uses a pressing member such as a coil spring to ensure reliable contact. In this case, the solar panel 5 can be appropriately pressed to avoid floating. Therefore, the solar panel 5 can be prevented from contacting and interfering with surrounding components.

[0159] In addition, it is preferable that the spacer 8 is arranged at least at a position substantially facing the contact member 15 .

[0160] Thus, even if the solar panel 5 is pressed from below by the contact member 15 or the like, the pressing force can be resisted via the spacer 8 and the solar panel 51 can be stably held.

[0161] In addition, the outer peripheral frame 6 is provided with a hole 63 for locking at least a part of the gasket 8 .

[0162] Thereby, the spacer 8 can be reliably arranged at an appropriate position.

[0163] [Modifications]

[0164] Furthermore, although the embodiments of the present disclosure have been described above, the present disclosure is not limited to these embodiments, and various modifications are possible without departing from the gist of the present disclosure.

[0165] For example, in an embodiment, when the solar panel 5 is arranged below the date wheel 3 (the second date wheel 32), a through hole 323 for allowing sunlight to pass through is provided in the date wheel 3 (the second date wheel 32), but for example, when the entire date wheel 3 is formed of a light-transmitting material, the date wheel 3 without the through hole 323 can also be arranged above the solar panel 5 (the roughly annular solar panel 52).

[0166] In addition, the shape of the outer peripheral frame 6 is not limited to the shape (substantially annular) shown in the embodiment.

[0167] The peripheral frame 6 only needs to be provided at a position at least opposite to the contact member 15 functioning as a pressing member, and may be an arc-shaped member along the outer periphery of the base 2. In this case, the arc-shaped peripheral frame is arranged at as equal intervals as possible at three or four positions including the position opposite to the contact member 15. Thus, the solar panel 5 can be stably pressed without tilting.

[0168] In the embodiment, the solar panel 5 provided below the date indicator 3 (second date indicator 32) is exemplified as being substantially annular, but the shape of the solar panel 5 provided below the date indicator 3 (second date indicator 32) is not limited to being substantially annular.

[0169] For example, it may be in a C shape or the like.

[0170] Furthermore, by configuring the first mounting portion 21, which is a space for arranging the solar panel 5 below the date wheel 3 (the second date wheel 32), to be roughly annular, any situation in which the solar panel 5 actually arranged on the first mounting portion 21 is roughly annular or C-shaped, etc., can be dealt with without changing the design.

[0171] In the embodiment, the hole 63 is provided in the outer frame 6 and the gasket 8 is mounted in the hole 63. However, the portion where the gasket 8 is mounted is not limited to the hole 63, and may be a recessed portion that does not penetrate vertically.

[0172] Furthermore, in the present embodiment, the case where the electronic device is the timepiece 100 or 200 is exemplified, but the electronic device is not limited to the timepiece.

[0173] The electronic device may be any device as long as it includes the date wheel 3 and can ensure space above and below the date wheel 3 for arranging the solar panel 5 , and is not limited to displaying the time by hands.

[0174] For example, it may be a calendar device that displays the date or day of the week instead of the time.

[0175] In addition, even when the electronic device is a clock, it is not limited to the clock that displays the time by hands as exemplified in the embodiment. For example, the time display may be displayed by a digital display unit such as a liquid crystal display unit.
