[0027] An embodiment of a module and an electronic device including the module of the present invention will be described with reference to the drawings. In this embodiment, the electronic device is an electronic watch worn on a user's wrist for use.

[0028] In addition, in the embodiment described below, various technically preferred limitations are added in order to implement the present invention, but the scope of the present invention is not limited to the following embodiment and the illustrated examples.

[0029] [structure]

[0030] Figure 1 1 is a plan view showing the main internal structure of an electronic timepiece (hereinafter referred to as a “timepiece”) according to the present embodiment. Figure 2 yes Figure 1 A cross-sectional view of the clock shown.

[0031] like Figure 1 and Figure 2 As shown, a timepiece 100 according to the present embodiment includes a device case 1 .

[0032] The device casing 1 of the present embodiment is formed in a hollow short column shape with upper and lower openings, and the hollow portion inside constitutes a storage space for storing various parts.

[0033] The device housing 1 is formed of a relatively hard synthetic resin such as engineering plastics or super engineering plastics. It should be noted that the material forming the device housing 1 is not limited to the materials exemplified here. The device housing 1 may also be formed of a metal material such as SUS.

[0034] On the outer side of the device housing 1 and Figure 2 A pair of strap attachment portions 11 (see FIG. 1 ) for attaching a strap (not shown) are provided at the upper and lower positions (the 12 o'clock position and the 6 o'clock position of the analog clock) in the middle. Figure 1 ).

[0035] In addition, in the device housing 1 Figure 2 Various operation buttons 12 (buttons, crowns, etc.) are provided on the left and right sides of the display.

[0036] Although not shown in the figure, the opening portion of the back side (non-visible side of the watch) of the device case 1 is closed by a back cover member (not shown). It should be noted that the back cover member may be formed integrally with the device case 1 .

[0037] In addition, if Figure 2 As shown, a coil spring 50 is provided to connect the solar cell panel (not shown) and the circuit board 6 .

[0038] Figure 3 is a perspective view showing a bezel, a windshield member, and a display unit provided on the surface side (visible side of the watch) of the device housing, Figure 4 yes Figure 3 The exploded perspective view of the bezel, windshield component and display unit shown in FIG. Figure 5is an exploded perspective view of the windshield component and the display unit. Figure 1 and Figure 2 , in order to facilitate observation of the internal structure, the bezel 2 and the windshield member 3 are shown with the bezel 2 and the windshield member 3 removed. Figure 3 The bezel 2 and the windshield member 3 shown are arranged, for example, on Figure 2 The device housing 1 shown ( Figure 2 the upper side in the image, the upper side of the display unit 4, the visible side).

[0039] A bezel 2 as an exterior member is provided on the surface side (the visible side of the timepiece) of the device case 1 so as to surround the opening portion. The bezel 2 is fixed to the device case 1 by, for example, screws (not shown).

[0040] like Figure 3 and Figure 4 As shown, the bezel 2 is a member formed in a substantially annular shape when the timepiece 100 is viewed from the visible side. The bezel 2 is formed of, for example, various resin materials. It should be noted that the material forming the bezel 2 is not particularly limited.

[0041] The opening portion on the surface side (visible side of the watch) of the device case 1 is closed by a windshield member 3. The windshield member 3 is a transparent member formed of, for example, a glass material, a transparent resin material, etc. The windshield member 3 is mounted on the device case 1 and assembled on the bezel 2 of the device case 1 via a windshield gasket 9 or the like. By mounting the windshield member 3 on the device case 1 and the bezel 2 via the windshield gasket, the opening portion on the surface side (visible side of the watch) of the device case 1 can be closed while ensuring the waterproofness (airtightness) in the device case 1.

[0042] In this embodiment, the windshield component 3 is integrally formed with a touch panel. Figure 4 as well as Figure 5 As shown, a flexible printed wiring board (hereinafter referred to as "FPC31") is connected. The other end side of FPC31 is electrically connected to the circuit substrate 6 described later, and can read the touch operation of the user, etc., and function as a touch panel. It should be noted that it is not necessary for the touch panel to be integrally formed with the windshield component 3. The windshield component 3 can also be a simple plate component such as glass. In this case, FPC31 is also not required.

[0043] Furthermore, a display unit 4 serving as a display section is provided below the windshield member 3 (on the non-visible side).

[0044] like Figure 5 As shown in FIG. 1 , the display unit 4 is a flat display unit including a liquid crystal display panel 41 , a light guide plate 42 , a reflector 44 (reflection member), etc. The liquid crystal display panel 41 and the light guide plate 42 are bonded and fixed with, for example, a double-sided tape 43 to form an integrated whole.

[0045] It should be noted that the display panel of the display unit 4 is not limited to a liquid crystal display panel, and may also be other flat panel displays, such as an organic electroluminescent display.

[0046] The liquid crystal display panel 41 has, for example, the following structure. That is, a pair of transparent electrodes (not shown) are provided on each opposing surface of a pair of upper and lower transparent substrates, and liquid crystal (not shown) is sealed between the pair of transparent substrates. Furthermore, a stacked structure is formed in which an upper polarizing plate is provided on the upper surface of the upper transparent substrate and a lower polarizing plate is provided on the lower surface of the lower transparent substrate.

[0047] The light guide plate 42 guides light from a light source (LED or the like) (not shown) provided in the device housing 1 to the liquid crystal display panel 41 .

[0048] A flexible printed wiring board (hereinafter referred to as "FPC411") is connected to the liquid crystal display panel 41, and a flexible printed wiring board (hereinafter referred to as "FPC421") is connected to the light guide plate 42. The other ends of FPC411 and FPC421 are electrically connected to a circuit board 6 described later and are appropriately controlled.

[0049] That is, the display unit 4 guides the light from the light source to the liquid crystal display panel 41 by the light guide plate 42, and selectively applies voltage to a pair of transparent electrodes (not shown) to change the orientation state of the liquid crystal (not shown) of the liquid crystal display panel 41, thereby controlling the transmission state of the light based on the liquid crystal. Thus, the display unit 4 is configured to appropriately display information such as the time according to the control.

[0050] The FPC 31 connected to the touch panel of the windshield member 3, the FPC 411 connected to the liquid crystal display panel 41 of the display unit 4, and the FPC 421 connected to the light guide plate 42 overlap and are integrated into one. Furthermore, when the bezel 2, the windshield member 3, and the display unit 4 are assembled into the device housing 1, for example, Figure 3 As shown, it is folded into a shape and size that can be easily accommodated in the device housing 1.

[0051] In the device housing 1, below the display unit 4 (at Figure 2 A circuit substrate 6 is arranged overlapping with the display unit 4 (the lower side, non-visible side).

[0052] In the present embodiment, the shielding member 7 is disposed on the upper surface of the circuit board 6 (that is, the surface on the side facing the display unit 4 ). Figure 6 FIG. 2 is a perspective view of a circuit substrate and a shielding member disposed thereon in this embodiment. Figure 6 In FIG. 1 , the mounting direction of the shielding member 7 on the circuit board 6 is indicated by a thick arrow.

[0053] like Figure 6 As shown in FIG. 1 and FIG. 2 , the circuit substrate 6 carries various circuit elements 61 as elements constituting the circuit on at least its upper surface. In addition, a shielding member 7 covering at least a part of these circuit elements 61 is placed on the circuit substrate 6. The circuit elements 61 covered by the shielding member 7 are protected from external impacts and the like.

[0054] like Figure 6 As shown in the figure, the shielding member 7 has a flat upper surface portion 71 and a side surface portion 72 vertically provided from the edge of the upper surface portion 71. The shielding member 7 is formed into a substantially box shape by a metal plate such as SUS, for example. It should be noted that the material or shape of the shielding member 7 is not limited to the material or shape illustrated here.

[0055] One or more substrate clamps 62 are provided on the circuit substrate 6 at the portion where the side surface portion 72 of the shielding component 7 is arranged. The substrate clamps 62 are formed of a metal material, and are holding portions fixed to the circuit substrate 6 by, for example, welding or the like. It should be noted that the method of fixing the substrate clamps 62 to the circuit substrate 6 is not limited to welding, and various methods can be applied. In addition, the number of substrate clamps 62 arranged at which position for one shielding component 7 is appropriately determined according to the position of the circuit element 61 and the installation conditions of each component.

[0056] Furthermore, the shield member 7 is in contact with the circuit board 6 that is grounded (GND) at the side surface (indirectly via the metal board clamp 62 ), and has the same potential as the ground.

[0057] The display unit 4 and the buffer member 8 are sandwiched and fixed by the circuit board 6 having the shield member 7 and the device housing 1 as a fixing member (particularly, the flange portion extending inward from the opening of the device housing 1). Figure 2 The height direction (Z direction) in the cross-sectional view shown is restricted in position by being sandwiched via the buffer member 8 .

[0058] In addition, if Figure 1 As shown, a wall 15 shown by a dashed line and larger than the display unit 4 and having the same shape as the display unit 4 is provided in the device housing 1 as a fixing member.

[0059] In this embodiment, the display unit 4 and the wall 15 of the device housing 1 are located in the front view of the device housing 1 (see Figure 1 ) is substantially octagonal. Buffer members 8 (8d, 8e) are arranged in gaps between portions located on both sides of the outer peripheral surface of the substantially octagonal display unit 4 and the inner peripheral surface wall 15 of the device housing 1.

[0060] Thus, the display unit 4 Figure 2The lateral direction (X direction) and the depth direction (Y direction) in the cross-sectional view shown are pressed and fixed to the wall 15 of the inner peripheral surface of the device housing 1 facing the surface by the two buffer members 8 (8d, 8e) arranged on the different surfaces. Figure 1 As shown, in the present embodiment, two cushioning members 8d and 8e are arranged on mutually adjacent outer peripheral surfaces among the eight outer peripheral surfaces of the octagonal display unit 4.

[0061] It should be noted that the arrangement positions of the two buffer members 8 (8d, 8e) are not limited to this. Figure 2 The lateral direction (X direction) and the depth direction (Y direction) in the cross-sectional view shown in FIG. Figure 1 In the front view (top view) of the octagonal display unit 4, a buffer member 8d is arranged on one of two adjacent outer peripheral surfaces across one outer peripheral surface, and a buffer member 8e is arranged on the other. By setting such an arrangement, a line connecting the wall 15 of the inner peripheral surface of the device housing 1 at the location where the buffer member 8d is arranged and the facing wall 15 and a line connecting the wall 15 of the inner peripheral surface of the device housing 1 at the location where the buffer member 8e is arranged and the facing wall 15 are orthogonal to each other. Therefore, the display unit 4 can be pressed and fixed to the wall 15 of the inner peripheral surface of the device housing 1 more stably.

[0062] Figure 7 is Figure 6 An enlarged cross-sectional view of the main part of portion VII shown surrounded by a dotted line.

[0063] like Figure 7 As shown, the substrate clamp 62 includes a holding portion 622 having a gap 621 corresponding to the thickness of the side surface portion 72 of the shield member 7 .

[0064] Figure 8 is a perspective view of a circuit substrate having a shielding member disposed on the upper surface in an embodiment, Fig. 9 is Figure 8 An enlarged cross-sectional view of the main part of the IX portion indicated by the dotted line.

[0065] like Figure 8 and Fig. 9 As shown, the side surface portion 72 of the shield member 7 is fitted into the gap 621 of the holding portion 622 , so that the shield member 7 (the side surface portion 72 of the shield member 7 ) is held by the board clamp 62 and locked to the circuit board 6 .

[0066] The holding portion 622 of the substrate clamp 62 may be slightly bendable like a leaf spring to clamp (hold) the side portion 72 inserted into the gap 621 , or may simply receive the side portion 72 in the gap 621 .

[0067] In either case, unlike the case where the shielding member 7 is directly fixed to the circuit substrate 6 by welding or the like, the shielding member 7 can be removed even after being inserted into the holding portion 622 of the substrate clamp 62. In this way, the shielding member 7 is fixed to the circuit substrate 6 via the substrate clamp 62, so that when a part of the circuit element 61 on the circuit substrate 6 covered by the shielding member 7 fails, the shielding member 7 can be removed to repair or replace the internal circuit element 61.

[0068] The shape, number of installations, height, etc. of the shielding member 7 are not limited to the example shown in the figure. Figure 6 and Figure 8 In the embodiment, a shielding member 7 formed integrally with the circuit substrate 6 is provided, but the shielding member 7 may be, for example, Fig.10 Divide into multiple parts like that.

[0069] Fig.10 This is a top view of a circuit board having a shielding component as viewed from the visible side. Fig.10 In the example shown, two shielding members 7 (large and small) are arranged on the circuit board 6. Fig.10 In the case where the smaller shielding component is set as 7a and the larger shielding component is set as 7b). Fig.10 As shown, when a plurality of shielding members 7 are provided on the circuit board 6 , it is preferable that the heights (dimensions in the case thickness direction) of all the shielding members 7 are made uniform.

[0070] It should be noted that a reflective plate 44 (reflective member) is provided below the light guide plate 42 of the display unit 4. Therefore, the buffer member 8 and the shielding member 7 located below the light guide plate 42 are not visible to the user via the reflective plate 44 (reflective member).

[0071] A buffer member (buffer) 8 is disposed on the upper surface (upper surface portion 71) of the shield member 7. Fig.10 The gray shadow in FIG. 8 represents the buffer component 8. Fig.10 In the embodiment, the buffer member 8 disposed on the shield member 7a is referred to as the buffer member 8a, and the buffer member 8 disposed on the shield member 7b is referred to as the buffer member 8b.

[0072] The buffer member 8 is disposed on the upper surface portion 71 of the shield member 7 and is in contact with the lower surface of the display unit 4 as a display portion (see Figure 2). The cushioning member 8 is formed of various resins that are excellent in shock absorption and can be expected to have an anti-slip effect. As a material for the cushioning member 8, for example, a high-functional polyurethane foam such as a microporous polymer sheet (such as "PORON" (registered trademark) manufactured by Rogers Inoac Co., Ltd.) is preferably used. It should be noted that the material forming the cushioning member 8 is not limited to this.

[0073] The cushioning member 8 is in surface contact with the lower surface of the display unit 4 and the upper surface of the shielding member 7. The shape, size, etc. of the cushioning member 8 (8a, 8b) are not particularly limited, but preferably have a certain area so that the pressure can be dispersed as evenly as possible. For example, Fig.10 As shown, in the case where two shielding components 7 (7a, 7b) are provided, Fig.10 The buffer member 8a is arranged on the entire upper surface of the smaller shield member 7a on the left side. In addition, the buffer member 8b is arranged on the outer periphery of the larger shield member 7b and at a position substantially symmetrical to the buffer member 8a arranged on the small shield member 7a, with the center being the center of the in-plane center of the circuit substrate 6. Fig.10 and Fig.11 As shown, when a plurality of shielding members 7 ( 7 a , 7 b ) are provided, the buffer members 8 ( 8 a , 8 b , or 8 c ) are provided corresponding to the plurality of shielding members 7 ( 7 a , 7 b ), respectively.

[0074] The configuration position of the buffer member 8 is not particularly limited, but in the present embodiment, Figure 1 As shown, the cushioning members 8 are arranged on the outer periphery of the display unit 4. It is preferred that a plurality of cushioning members 8 are arranged at symmetrical positions or near the center of the display unit 4. By arranging the cushioning members 8 approximately symmetrically on the outer periphery of the display unit 4, it is possible to avoid the pressure being concentrated on only one part.

[0075] In addition, the cushioning member 8a and the cushioning member 8b are preferably of the same shape. When a plurality of cushioning members 8 are provided, cushioning members of the same shape are used, and common parts can be used to reduce manufacturing costs.

[0076] In addition, when the heights (dimensions in the housing thickness direction) of the plurality of shielding members 7 are inconsistent and vary, it is preferable to adjust the thickness of the buffer member 8 provided on the upper surface of each shielding member 7 to make the heights consistent. Thus, the display unit 4 can be received by a substantially flat surface without shaking.

[0077] It should be noted that, in the shielding component 7, Figure 6 , Figure 8 Even when connected as shown, it is preferable that a plurality of buffer members 8 are arranged at symmetrical positions or in the vicinity thereof, avoiding the central portion of the display unit 4 .

[0078] Furthermore, when a plurality of buffer members 8 are provided, the shapes and sizes thereof may be different.

[0079] For example, Fig.11 As shown in FIG. 1 , the area of ​​the buffer member 8c provided on the upper surface portion 71 of the larger shielding member 7b may be larger than the area of ​​the buffer member 8a provided on the smaller shielding member 7a. In this case, the buffer member 8c is preferably arranged at the outer peripheral edge of the shielding member 7b and approximately symmetrically with the buffer member 8a provided on the shielding member 7a, with the center in the plane of the circuit substrate 6 being the center, avoiding the central portion of the display unit 4 provided to overlap with the circuit substrate 6.

[0080] It should be noted that the shapes of the device housing 1 and the display unit 4 are not limited to the shapes shown in the drawings in this embodiment.

[0081] Fig.12 Modifications of the timepiece in which the shapes of the device housing and the display unit are different are shown.

[0082] For example Fig.12 As schematically shown, when the device case 1a of the timepiece 100a is viewed from the front, the outer shapes of the device case 1a and the display unit 4a may both be rectangular or the like.

[0083] When the outer shape of the device housing 1a and the display unit 4a is rectangular, for example, the buffer members 8 (8f, 8g) are arranged in the gap between two adjacent sides of the outer periphery of the display unit 4a and the portions of the inner peripheral wall 15a of the device housing 1a that are opposite to the two sides of the display unit 4a. Fig.12 In the lateral direction (X direction) and the depth direction (Y direction), the display unit 4a is pressed and fixed to the wall 15 of the inner peripheral surface of the opposing device housing 1 by using the buffer components 8f and the buffer components 8g arranged between the adjacent inner peripheral surfaces of the device housing 1 and the adjacent outer peripheral surfaces of the corresponding display units 4a.

[0084] In addition, in the case where the outer shapes of the device housing 1a and the display unit 4a are both rectangular, the display unit 4 is also provided with a buffer member 8 (in Fig.12 The buffer members 8a and 8b are arranged on the upper surface of the shielding member 7 provided on the circuit substrate 6. Furthermore, the buffer members 8a and 8b are preferably arranged at positions approximately symmetrical to each other with the outer periphery of the shielding member 7 and the in-plane center of the circuit substrate 6 being the center, avoiding the central portion of the display unit 4 which is overlapped and arranged on the circuit substrate 6.

[0085] [effect]

[0086] As described above, in this embodiment, when the display unit 4 as the display portion is held in the device housing 1, the display unit 4 is arranged in the device housing 1 and below the windshield member 3. The shielding member 7 is arranged on the surface of the circuit substrate 6 facing the display unit 4, and the buffer member 8 is arranged on the upper surface of the shielding member 7. Then, the circuit substrate 6 is arranged in the device housing 1 from the back side (i.e., the back cover member side) of the display unit 4. As a result, the display unit 4 is pushed up from the back side and fixed at a predetermined position.

[0087] In this embodiment, the buffer member 8 is interposed between the shielding member 7 and the display unit 4. The display unit 4 is held at a predetermined position by the anti-slip effect of the buffer member 8, and is not easily moved or dropped. In addition, when the clock 100 is impacted from the outside, the buffer member 8 also absorbs the impact, thereby preventing the display unit 4 from being damaged.

[0088] In addition, if Figure 1 As shown in FIG. 1 , if the buffer member 8 between the shield member 7 and the display unit 4 is arranged on the outer peripheral side of the display unit 4 away from the central portion in the in-plane direction of the display unit 4, it is possible to prevent a large pressure from being applied to the central portion of the liquid crystal display panel 41 of the display unit 4, which is relatively weak to pressure. In addition, since the shield member 7 absorbs the impact by the buffer member 8, it is possible to prevent deformation, etc., and avoid contact with the internal circuit element 61, short circuit, etc.

[0089] In addition, if a plurality of buffer members 8 (in the present embodiment, two buffer members 8a and 8b) are arranged at symmetrical positions centered on the center of the display unit 4 or at positions close thereto, even when external force is applied to the timepiece 100, the pressure and impact can be evenly dispersed, and the display unit 4 can be more reliably protected from damage, etc.

[0090] Moreover, according to the module of this embodiment (the holding structure of the display part), there is no need to fix the display unit 4 based on bonding, screw fastening, etc., which not only helps to reduce the number of parts and assembly man-hours, but also allows for easy handling by only repairing or replacing the display unit 4 in the event of a malfunction.

[0091] Furthermore, since the display unit 4 is disposed upward, the shield member 7 does not fall off upward, and the shield member 7 can be stably disposed on the circuit board 6 even without fixing by soldering or the like.

[0092] [Effect]

[0093] As described above, the module (display unit holding structure) in the present embodiment comprises: a display unit 4 as a flat display unit; a circuit substrate 6, which is arranged below the display unit 4 so as to overlap with the display unit 4 and has a shielding component 7 covering at least a portion of a circuit element 61 mounted on a surface opposite to the display unit; and a buffer component 8, which is arranged on the upper surface (above the upper surface portion 71) of the shielding component 7 and abuts against the lower surface of the display unit 4.

[0094] Thus, the display unit 4 can be held at a predetermined position simply by placing the display unit 4 on the shielding member 7, and since the display unit 4 is placed via the buffer member 8, it also has excellent durability against external impacts. In addition, since the display unit 4 is placed at the top, the shielding member will not be detached upward, and can be stably placed on the circuit board 6 even without fixing by welding or the like.

[0095] Thus, in this embodiment, the display unit 4 and the shielding member 7 are only overlapped and arranged without being fixed by bonding, screwing, etc. Therefore, even after being assembled in the device housing 1, the display unit 4 and the shielding member 7 can be easily removed. Thus, in the case where the display unit 4 has a malfunction or the circuit element under the shielding member 7 has a malfunction, the device itself can be repaired or replaced by removing only the malfunctioning part without damaging the device itself. Therefore, in the case where a part of the display unit 4 or the like has a malfunction, it is sufficient to replace the minimum range, and the device (clock 100) can be used for a long time without waste.

[0096] Furthermore, the display unit 4 is usually an electronic device that performs display. Therefore, there is no need to separately provide a component for fixing, which also has the effect of reducing the number of components, reducing the number of assembly man-hours, and reducing costs.

[0097] In addition, in the present embodiment, the cushioning member 8 is disposed on the outer peripheral side of the display unit 4 serving as a display section.

[0098] If pressure is applied to the central portion of the display unit 4 including the liquid crystal display panel 41 and the like in the in-plane direction, the liquid crystal portion may be damaged. In this regard, as in the present embodiment, the buffer member 8 between the display unit 4 and the shielding member 7 is arranged on the outer peripheral side of the display unit 4, thereby avoiding the application of pressure to the central portion of the liquid crystal display panel 41 and the like of the display unit 4 and preventing the occurrence of a defect in the display unit 4.

[0099] In addition, in the present embodiment, the cushioning member 8 is in surface contact with the lower surface of the display unit 4 as the display portion and the upper surface of the shielding member 7 .

[0100] In this way, by making the display unit 4 and the shielding member 7 contact with each other not at points but at surfaces, it is possible to disperse the pressure and prevent strong pressure from being applied only to a part.

[0101] Furthermore, since the shielding member 7 is prevented from being dented or deformed, various circuit elements 61 below the shielding member 7 can be protected, and the shielding member 7 as a metal part can be prevented from bending and contacting the circuit elements 61 and causing a short circuit.

[0102] In addition, in the present embodiment, a plurality of cushioning members 8 are arranged at symmetrical positions or in the vicinity thereof, avoiding the central portion of the display unit 4 serving as the display portion.

[0103] As described above, if pressure is applied to the central portion of the display unit 4 including the liquid crystal display panel 41 in the in-plane direction, the liquid crystal portion may be damaged. In this regard, by avoiding the central portion and arranging a plurality of the buffer members 8 at symmetrical positions, the force can be effectively dispersed even when pressure is applied, avoiding the situation where the force is concentrated at a certain point.

[0104] This makes it possible to more reliably avoid damage to the liquid crystal display panel 41 of the display unit 4 and the like, deformation of the shielding member, and the like.

[0105] In addition, in the present embodiment, the shielding member 7 is held by the substrate clamp 62 which is a holding portion fixed to the circuit substrate 6 .

[0106] When the shield member 7 is directly soldered to the circuit board 6, a space for soldering needs to be ensured, and the mounting area on the board is reduced. In this regard, if the shield member 7 is held by the board jig 62, the reduction in the mounting area can be suppressed.

[0107] In addition, if the shielding member 7 is soldered to the circuit substrate 6, the entire circuit substrate 6 must be removed when accessing the circuit element 61 covered by the shielding member 7. In contrast, in the present embodiment, the shielding member 7 is held only by the substrate clamp 62. Therefore, even after the shielding member 7 is assembled, if a malfunction occurs, the shielding member 7 can be easily removed to access the circuit element 61, and only the necessary part can be repaired or replaced. Therefore, the time and cost of replacing the entire circuit substrate 6 can be saved.

[0108] When a plurality of shielding members 7 are provided, a plurality of buffer members 8 are provided corresponding to the plurality of shielding members 7 .

[0109] Thus, the display unit 4 can be stably received, and damage to the liquid crystal display panel 41 of the display unit 4 and the like, deformation of the shielding member, and the like can be effectively prevented.

[0110] Moreover, when the module of this embodiment (holding structure for holding display unit 4 and other display parts) is applied to various electronic devices such as clocks (electronic clocks) 100, there is no need to fix the display unit 4 and other display parts to the device housing 1, windshield component 3, etc. by bonding or the like.

[0111] Therefore, when a malfunction occurs in the display unit 4, only the display unit 4 can be repaired or replaced, and the repair cost can be reduced compared to replacing other components such as the device housing 1 and the windshield member 3 together.

[0112] In addition, when the display unit 4 or other display parts are screwed to the device housing 1 or the like for fixing, space for screwing is required, and after fixing, free space corresponding to the screw head must be ensured. Therefore, the installation area and installation capacity in the device housing 1 become smaller. In this regard, when the display unit 4 or other display parts are held on the shielding member 7 via the buffer member 8 as in the present embodiment, it is not necessary to ensure parts and space for fixing the display unit 4, which can reduce costs, achieve overall lightweighting of the device, and ensure a larger installation area. Moreover, by ensuring a larger installation area, the circuit substrate 6 itself can be reduced, which also contributes to the miniaturization of the entire electronic device such as the clock 100.

[0113] It should be noted that, although the embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various modifications can be made without departing from the gist of the present invention.

[0114] For example, this embodiment illustrates a case where the electronic timepiece is the timepiece 100 and a case where the holding structure for holding a display unit such as the display unit 4 is mounted on the timepiece 100, but the device to which the holding structure for holding a display unit can be applied is not limited thereto.

[0115] For example, it can be widely used in various wearable devices such as smart watches, sports watches, heart rate monitors that display biological information such as heart rate and blood flow in addition to time, blood pressure monitors, devices that display environmental information such as temperature and air pressure, and other electronic devices that display various data.

[0116] Several embodiments of the present invention have been described above, but the scope of the present invention is not limited to the above-described embodiments, and includes the scope of the invention described in the claims and the scope equivalent thereto.
