[0009] While referring to the drawings, an embodiment of a module according to the present invention and an electronic device including the module will be described. In this embodiment, a case where the electronic device is an electronic clock worn on the user's arm will be exemplified and described. In addition, although various technically preferable limitations are imposed on the embodiments described below in order to implement the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0010] [Configuration] FIG. 1 is a plan view showing the internal main part configuration of an electronic clock (hereinafter simply referred to as "clock") in this embodiment, and FIG. 2 is a cross-sectional view of the clock shown in FIG. 1.

[0011] As shown in FIGS. 1 and 2, the clock 100 in this embodiment has a device case 1. The device case 1 of this embodiment is formed in a hollow short column shape with openings at the top and bottom, and the internal hollow part constitutes a storage space for storing various components. The equipment case 1 is formed from a relatively hard synthetic resin, such as engineering plastic or super engineering plastic. However, the material used to form the equipment case 1 is not limited to those exemplified herein. The equipment case 1 may also be formed from a metal material, such as stainless steel (SUS).

[0012] On the outer surface of the device case 1, at the upper and lower positions in Figure 2 (the 12 o'clock and 6 o'clock positions in an analog clock), there is a pair of band attachment parts 11 (see Figure 1) to which a band (not shown) can be attached. Furthermore, various operation buttons 12 (push buttons, crowns, etc.) for the user to perform various input operations are provided on the left and right sides of the device case 1 as shown in Figure 2. Although not shown in the illustration, the opening on the back side of the device case 1 (the non-visible side in the watch) is closed by a back cover member (not shown). The back cover member may be integrally formed with the device case 1. Furthermore, as shown in Figure 2, a coil spring 50 is provided to connect the solar panel (not shown) and the circuit board 6.

[0013] Figure 3 is a perspective view showing the bezel, crystal, and display unit located on the front side of the device case (the viewing side in the watch). Figure 4 is an exploded perspective view of the bezel, crystal, and display unit shown in Figure 3. Figure 5 is an exploded perspective view of the crystal and display unit. Note that in Figures 1 and 2, the bezel 2 and crystal 3 are shown removed to make the internal structure easier to see. The bezel 2 and crystal 3 shown in Figure 3 are positioned, for example, on top of the device case 1 shown in Figure 2 (the upper side in Figure 2, above the display unit 4, the viewing side).

[0014] On the front side of the device case 1 (the side visible in the watch), a bezel 2 is provided as an exterior component to surround the opening. The bezel 2 is fixed to the device case 1, for example, by screws (not shown). As shown in Figures 3 and 4, the bezel 2 is a component formed in a substantially annular shape when the watch 100 is viewed from the viewing side. The bezel 2 is formed from, for example, various resin materials. The material used to form the bezel 2 is not particularly limited.

[0015] The opening on the front side (the viewing side in the watch) of the device case 1 is closed by the crystal member 3. The crystal member 3 is a transparent member formed from, for example, glass or transparent resin material. The crystal member 3 is attached to the device case 1 or the bezel 2 mounted on the device case 1 via a crystal gasket 9 or the like. By attaching the crystal member 3 to the device case 1 or the bezel 2 via a crystal gasket, the opening on the front side (the viewing side in the watch) of the device case 1 can be closed while ensuring the waterproofness (airtightness) of the device case 1.

[0016] In this embodiment, the windshield member 3 has a touch panel integrally formed with it, and as shown in Figures 4 and 5, a flexible printed circuit board (hereinafter referred to as "FPC31") is connected to it. The other end of the FPC31 is electrically connected to a circuit board 6, which will be described later, and is capable of reading touch operations by the user and functioning as a touch panel. It should be noted that it is not essential for the windshield member 3 to have a touch panel integrally formed with it. The windshield member 3 may be just a simple plate member such as glass. In this case, it is not necessary to provide the FPC31.

[0017] Furthermore, a display unit 4 is provided below the windshield member 3 (on the non-visible side) as a display unit. As shown in Figure 5, the display unit 4 is a flat display section and includes a liquid crystal display panel 41, a light guide plate 42, and a reflector plate 44 (reflective member). The liquid crystal display panel 41 and the light guide plate 42 are attached and fixed together, for example, by double-sided tape 43. The display panel of the display unit 4 is not limited to a liquid crystal display panel; for example, it may be an organic electroluminescent display or other flat display.

[0018] The liquid crystal display panel 41 has, for example, the following configuration. Specifically, a pair of transparent electrodes (not shown) are provided on each opposing surface of a pair of upper and lower transparent substrates, and a liquid crystal (not shown) is sealed between these two transparent substrates. 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, resulting in a laminated structure. The light guide plate 42 also guides light from a light source (such as an LED) located inside the device case 1 to the liquid crystal display panel 41. A flexible printed circuit board (hereinafter referred to as "FPC411") is connected to the liquid crystal display panel 41, and a flexible printed circuit 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, which will be described later, and controlled as appropriate.

[0019] In other words, the display unit 4 guides light from a light source to the liquid crystal display panel 41 using a light guide plate 42, and selectively applies voltage to a pair of transparent electrodes (not shown) to change the orientation of the liquid crystal (not shown) in the liquid crystal display panel 41, thereby controlling the light transmission state by the liquid crystal. As a result, the display unit 4 is configured to display information such as the time as appropriate according to the control.

[0020] The FPC31 connected to the touch panel of the crystal member 3, the FPC411 connected to the liquid crystal display panel 41 of the display unit 4, and the FPC421 connected to the light guide plate 42 are stacked and combined into one unit. When assembling the bezel 2, crystal member 3, and display unit 4 into the device case 1, they are folded into a shape and size that is easy to accommodate in the device case 1, as shown in Figure 3, for example.

[0021] Inside the device case 1, a circuit board 6 is positioned below the display unit 4 (downwards in Figure 2, on the non-visible side), superimposed on the display unit 4. In this embodiment, the shield member 7 is arranged on the upper surface of the circuit board 6 (i.e., the surface facing the display unit 4). Figure 6 is a perspective view of the circuit board and the shield member arranged thereon in this embodiment. In Figure 6, the thick arrow indicates the direction in which the shield member 7 is attached to the circuit board 6. As shown in Figure 6, the circuit board 6 has various circuit elements 61, which are components of an electrical circuit, mounted on at least its upper surface. A shielding member 7 is placed on the circuit board 6 to cover at least some of these circuit elements 61. The circuit elements 61 covered by the shielding member 7 are protected from external impacts and the like.

[0022] As shown in Figure 6, the shield member 7 has a flat upper surface portion 71 and a side portion 72 that extends vertically from the edge of the upper surface portion 71. The shield member 7 is formed in a substantially box shape from sheet metal such as SUS. However, the material and shape of the shield member 7 are not limited to those exemplified herein. One or more board clips 62 are provided on the circuit board 6 in the area where the side portion 72 of the shielding member 7 is positioned. The board clips 62 are made of a metal material and are retaining parts fixed to the circuit board 6 by means such as soldering. Note that the method of fixing the board clips 62 to the circuit board 6 is not limited to soldering and various methods can be applied. The number and position of board clips 62 to be placed for a single shielding member 7 are determined as appropriate according to the position of the circuit elements 61 and the mounting status of each component. Furthermore, the shielding member 7 is in contact with the circuit board 6, which is ground (GND), on its side (indirectly via a metal board clip 62), and is at the same potential as ground.

[0023] The display unit 4 and the buffer member 8 are fixed by being sandwiched between the circuit board 6 having the shield member 7 and the equipment case 1, which is a fixing member (particularly the inwardly protruding flange portion at the opening of the equipment case 1). In this way, the position in the height direction (Z direction) in the cross-sectional view shown in Figure 2 is restricted by being sandwiched via the buffer member 8.

[0024] Furthermore, as shown in Figure 1, the fixed member, the equipment case 1, is provided with a wall 15, indicated by a dashed line, which is larger than the display unit 4 and has the same shape as the display unit 4. In this embodiment, the display unit 4 and the wall 15 of the equipment case 1 are approximately octagonal in a front view of the equipment case 1 (see Figure 1). Cushioning members 8 (8d, 8e) are placed in the gap between the two sides of the outer surface of this approximately octagonal display unit 4 and the inner surface wall 15 of the equipment case 1.

[0025] As a result, the lateral (X-direction) and depth (Y-direction) directions of the display unit 4 in the cross-sectional view shown in Figure 2 are fixed by being pressed against the inner circumferential wall 15 of the equipment case 1 facing these faces by two cushioning members 8 (8d, 8e) positioned on these different faces. As shown in Figure 1, in this embodiment, the two cushioning members 8 (8d, 8e) are positioned on mutually adjacent circumferential surfaces among the eight circumferential surfaces of the octagonal display unit 4. The placement of the two cushioning members 8 (8d, 8e) is not limited to these positions. For example, cushioning member 8d may be placed on one of the adjacent outer surfaces of the octagonal display unit 4 in the front view (plan view) of Figure 1, which corresponds to the horizontal direction (X direction) and depth direction (Y direction) in the cross-sectional view shown in Figure 2, and cushioning member 8e may be placed on the other. With this arrangement, the line connecting the inner surface wall 15 of the equipment case 1 where cushioning member 8d is placed and the opposing wall 15 is perpendicular to the line connecting the inner surface wall 15 of the equipment case 1 where cushioning member 8e is placed and the opposing wall 15 is perpendicular to each other. As a result, the display unit 4 can be pressed more stably against the inner surface wall 15 of the equipment case 1 and fixed in place.

[0026] Figure 7 is an enlarged cross-sectional view of the main part of section VII, which is enclosed by a dashed line in Figure 6. As shown in Figure 7, the substrate clip 62 is equipped with a holding portion 622 having a gap 621 corresponding to the thickness of the side portion 72 of the shielding member 7. Figure 8 is a perspective view of a circuit board in which a shielding member is arranged on the upper surface in an embodiment, and Figure 9 is an enlarged cross-sectional view of the main part of section IX, which is enclosed by a dashed line in Figure 8. As shown in Figures 8 and 9, the shield member 7 (the side portion 72 of the shield member 7) is held by the substrate clip 62 and locked onto the circuit board 6 by fitting the side portion 72 of the shield member 7 into the gap 621 of the holding portion 622.

[0027] The holding portion 622 of the circuit board clip 62 is capable of bending slightly like a leaf spring, and may be configured to clamp (grip) the side portion 72 fitted into the gap 621, or it may simply be designed to receive the side portion 72 into the gap 621. In either case, unlike when the shielding member 7 is directly fixed to the circuit board 6 by soldering or the like, the shielding member 7 can be removed even after it has been fitted into the holding portion 622 of the circuit board clip 62. By fixing the shielding member 7 to the circuit board 6 via the circuit board clip 62 in this way, if a malfunction occurs in any of the circuit elements 61 on the circuit board 6 covered by the shielding member 7, the shielding member 7 can be removed and the internal circuit elements 61 can be repaired or replaced.

[0028] The shape, number, and height of the shield member 7 are not limited to the illustrated examples. Figures 6 and 8 illustrate a case where a single shield member 7 is formed as a continuous unit on the circuit board 6, but the shield member 7 may be divided into multiple parts, for example, as shown in Figure 10. Figure 10 is a plan view of a circuit board equipped with shielding members, as seen from the viewing side. In the example shown in Figure 10, two shielding members 7 of different sizes (in Figure 10, the smaller shielding member is denoted as 7a and the larger shielding member as 7b) are arranged on the circuit board 6. As shown in Figure 10, when multiple shielding members 7 are provided on the circuit board 6, it is preferable to make the height (dimension in the case thickness direction) of all shielding members 7 the same. Furthermore, a reflector 44 (reflective member) is provided on the underside of the light guide plate 42 of the display unit 4. Therefore, the buffer member 8 and shield member 7, which are located on the underside of the light guide plate 42 via the reflector 44 (reflective member), are not visible to the user.

[0029] A cushioning member (cushion material) 8 is placed on the upper surface (upper surface portion 71) of the shield member 7. In Figure 10, the cushioning member 8 is shown with a gray shaded area. In Figure 10, the cushioning member 8 placed on the shield member 7a is referred to as cushioning member 8a, and the cushioning member 8 placed on the shield member 7b is referred to as cushioning member 8b. The buffer member 8 is positioned on the upper surface 71 of the shield member 7 and is in contact with the lower surface of the display unit 4, which is the display unit (see Figure 2). The cushioning member 8 is formed from various resins or the like that offer excellent shock absorption and anti-slip properties. As the material for the cushioning member 8, high-performance urethane foam such as microcellular polymer sheets (e.g., "PORON" (registered trademark) manufactured by Rogers Inoac Co., Ltd.) is preferably used. However, the material used to form the cushioning member 8 is not limited to this.

[0030] 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 it is preferable that it has a certain area so that the pressure can be distributed as uniformly as possible. For example, as shown in Figure 10, when two shield members 7(7a, 7b) of different sizes are provided, a buffer member 8a is placed over the entire upper surface of the smaller shield member 7a on the left side of Figure 10. On the larger shield member 7b, a buffer member 8b is placed at its outer edge such that it is approximately symmetrical to the buffer member 8a placed on the smaller shield member 7a, with respect to the in-plane center of the circuit board 6. As shown in Figures 10 and 11, when multiple shield members 7(7a, 7b) are provided, buffer members 8(8a, 8b, or 8c) are provided corresponding to each of the multiple shield members 7(7a, 7b).

[0031] The placement of the buffer members 8 is not particularly limited, but in this embodiment, as shown in Figure 1, they are placed on the outer periphery of the display unit 4. It is preferable to arrange multiple buffer members 8 symmetrically or near the center of the display unit 4, avoiding the central part. By arranging the buffer members 8 almost symmetrically on the outer periphery of the display unit 4, it is possible to avoid the concentration of pressure on only one part.

[0032] Furthermore, it is preferable that the cushioning members 8a and 8b have the same shape. By using cushioning members of the same shape when multiple cushioning members 8 are provided, common parts can be used, and manufacturing costs can be reduced. Furthermore, if the dimensions (in the case thickness direction) of the multiple shield members 7 are not uniform and vary, it is preferable to adjust the height by adjusting the thickness of the cushioning member 8 provided on the upper surface of each shield member 7. In this way, the display unit 4 can be supported on a nearly flat surface without rattling. Even when the shield member 7 is a single continuous unit as shown in Figures 6 and 8, it is preferable to arrange multiple buffer members 8 in symmetrical positions or near the central part of the display unit 4, avoiding the central part.

[0033] Furthermore, if multiple cushioning members 8 are provided, their shapes and sizes do not have to be the same. For example, as shown in Figure 11, the buffer member 8c provided on the upper surface 71 of the larger shield member 7b may have a larger area than the buffer member 8a placed on the smaller shield member 7a. In this case as well, it is preferable that the buffer member 8c avoids the central part of the display unit 4 superimposed on the circuit board 6, and is positioned such that it is approximately symmetrical to the buffer member 8a placed on the shield member 7a when the outer edge of the shield member 7b is centered on the in-plane center of the circuit board 6.

[0034] Note that the shapes of the equipment case 1 and the display unit 4 are not limited to those shown in this embodiment. Figure 12 shows variations of the clock with different device cases and display unit shapes. For example, as schematically shown in Figure 12, when the device case 1a of the clock 100a is viewed from the front, the external shapes of both the device case 1a and the display unit 4a may be rectangular or the like. If the external shape of the equipment case 1a and the display unit 4a is rectangular, for example, cushioning members 8 (8f, 8g) are placed in the gap between each of two adjacent sides of the outer perimeter of the display unit 4a and the portion of the inner circumferential wall 15a of the equipment case 1a that faces those two sides of the display unit 4a. As a result, in the lateral direction (X direction) and depth direction (Y direction) of Figure 12, the cushioning members 8f and 8g placed between the adjacent inner circumferential surfaces of the equipment case 1 and the corresponding adjacent outer circumferential surfaces of the display unit 4a press the display unit 4a against the inner circumferential wall 15 of the equipment case 1 and fix it in place.

[0035] Furthermore, even when the external shapes of both the equipment case 1a and the display unit 4a are rectangular, the display unit 4 is positioned on the upper surface of the shield member 7 provided on the circuit board 6 via a buffer member 8 (buffer members 8a and 8b in Figure 12). It is preferable that the buffer members 8a and 8b are positioned so as to avoid the central part of the display unit 4 superimposed on the circuit board 6, and so as to be approximately symmetrical with respect to the outer edge of the shield member 7, with respect to the in-plane center of the circuit board 6.

[0036] [Effect] As described above, in this embodiment, when the display unit 4, which is the display section, is held inside the equipment case 1, the display unit 4 is placed inside the equipment case 1 and below the windshield member 3. A shield member 7 is placed on the surface of the circuit board 6 facing the display unit 4, and a buffer member 8 is placed on the upper surface of the shield member 7. Then the circuit board 6 is placed inside the equipment case 1 from the back side of the display unit 4 (i.e., the side of the back cover member). As a result, the display unit 4 is pushed up from the back side and fixed in the predetermined position. In this embodiment, by interposing a cushioning member 8 between the shield member 7 and the display unit 4, the anti-slip effect of the cushioning member 8 holds the display unit 4 in place, making it difficult for it to move or come loose. Furthermore, even when the clock 100 is subjected to an external impact, the cushioning member 8 absorbs the impact, thus preventing damage to the display unit 4.

[0037] Furthermore, as shown in Figure 1, if the buffer member 8 interposed between the shield member 7 and the display unit 4 is positioned on the outer periphery of the display unit 4, avoiding the central part in the in-plane direction of the display unit 4, it is possible to prevent large pressure from being applied to the central part of the liquid crystal display panel 41 of the display unit 4, which is susceptible to pressure. In addition, the shield member 7 can be prevented from deforming by the shock absorbed by the buffer member 8, thereby preventing contact with the internal circuit elements 61, short circuits, etc. Furthermore, by arranging multiple cushioning members 8 (in this embodiment, two cushioning members 8a and 8b) at symmetrical positions or close to the center of the display unit 4, pressure and impact can be uniformly distributed when an external force is applied to the clock 100, thereby more reliably protecting the display unit 4 from damage.

[0038] Furthermore, according to the module (display unit holding structure) of this embodiment, there is no need to fix the display unit 4 by adhesive or screws, which contributes to reducing the number of parts and assembly man-hours. In addition, if a malfunction occurs in the display unit 4, only the display unit 4 needs to be repaired or replaced, making it easy to address the issue. Furthermore, because the display unit 4 is positioned upwards, the shield member 7 will not detach upwards, and the shield member 7 can be stably positioned on top of the circuit board 6 without the need for soldering or other fixing methods.

[0039] [effect] As described above, the module (display unit holding structure) in this embodiment comprises a display unit 4 as a flat display unit, a circuit board 6 positioned below the display unit 4 and superimposed on the display unit 4, with a shielding member 7 mounted on the surface facing the display unit that covers at least some of the circuit elements 61, and a buffering member 8 positioned on the upper surface (above the upper surface portion 71) of the shielding member 7 and in contact with the lower surface of the display unit 4. As a result, the display unit 4 is held in place simply by placing it on the shield member 7, and because it is mounted via the cushioning member 8, it has excellent durability against external impacts. In addition, because the display unit 4 is positioned upwards, the shield member will not come off upwards, and it can be stably placed on the circuit board 6 without fixing it by soldering or the like.

[0040] As described above, in this embodiment, neither the display unit 4 nor the shield member 7 are fixed by adhesive or screws, simply by being placed on top of each other. Therefore, even after being assembled inside the equipment case 1, the display unit 4 and the shield member 7 can be easily removed. This means that if a malfunction occurs in the display unit 4 or a circuit element under the shield member 7, only the faulty part can be removed and repaired or replaced without damaging the equipment itself. Therefore, if there is a malfunction in some parts such as the display unit 4, only a minimal amount of replacement is needed, and the equipment (clock 100) can be used for a long time without waste. Furthermore, the display unit 4 is something that is normally included in electronic devices that perform displays. Therefore, there is no need to separately provide additional parts for fixing, resulting in cost reductions through a reduction in the number of parts and assembly man-hours.

[0041] In this embodiment, the buffer member 8 is positioned on the outer periphery of the display unit 4, which is the display section. The display unit 4, including the liquid crystal display panel 41, is susceptible to damage to its liquid crystal portion if pressure is applied to its central part in the in-plane direction. In this embodiment, by arranging the buffer member 8, which is interposed between the display unit 4 and the shield member 7, on the outer periphery of the display unit 4, it is possible to prevent pressure from being applied to the central part of the liquid crystal display panel 41 of the display unit 4, thereby preventing malfunctions in the display unit 4.

[0042] In this embodiment, the buffer member 8 is in surface contact with the lower surface of the display unit 4, which is the display section, and the upper surface of the shield member 7. In this way, by making contact between the display unit 4 and the shield member 7 over a surface rather than at a point, the pressure can be distributed, preventing strong pressure from being applied to only one part. Therefore, the display unit 4 is less likely to be damaged. In addition, in order to prevent the shield member 7 from denting or deforming, the various circuit elements 61 below the shield member 7 can be protected, and a situation in which the metal part of the shield member 7 bends and comes into contact with the circuit elements 61, causing a short circuit, can be prevented.

[0043] In this embodiment, multiple buffer members 8 are arranged symmetrically or near the central part of the display unit 4, which is the display section. As mentioned above, the display unit 4, including the liquid crystal display panel 41, is susceptible to damage to the liquid crystal portion if pressure is applied to its central part in the in-plane direction. By arranging multiple buffer members 8 in symmetrical positions, avoiding the central part, the force can be effectively distributed even when pressure is applied, preventing the force from concentrating at a single point. This makes it possible to more reliably avoid damage to the liquid crystal display panel 41 of the display unit 4, deformation of the shielding material, etc.

[0044] In this embodiment, the shield member 7 is held in place by a substrate clip 62, which is a retaining part fixed to the circuit board 6. If the shielding member 7 is soldered directly to the circuit board 6, it becomes necessary to secure space for soldering, which reduces the mounting area on the board. However, by holding the shielding member 7 with a board clip 62, the reduction in mounting area can be minimized. Furthermore, if the shielding member 7 is soldered to the circuit board 6, the entire circuit board 6 must be removed to access the circuit elements 61 covered by the shielding member 7. In contrast, in this embodiment, the shielding member 7 is simply held in place by the board clip 62. Therefore, even after the shielding member 7 has been assembled, if a problem occurs, the shielding member 7 can be easily removed to access the circuit elements 61, and only the necessary parts can be repaired or replaced. This eliminates the hassle and cost of replacing the entire circuit board 6.

[0045] Furthermore, if multiple shield members 7 are provided, multiple buffer members 8 are also provided corresponding to each of the multiple shield members 7. This allows the display unit 4 to be supported stably, effectively preventing damage to the liquid crystal display panel 41 of the display unit 4, deformation of the shielding material, and so on.

[0046] Furthermore, when the module of this embodiment (a holding structure that holds the display unit such as the display unit 4) is applied to electronic devices such as various clocks (electronic clocks) 100, it is not necessary to fix the display unit such as the display unit 4 to the device case 1 or the windshield member 3 by adhesive or the like. Therefore, if a malfunction occurs in the display unit 4, only the display unit 4 can be repaired or replaced, which reduces repair costs compared to replacing other components such as the equipment case 1 or the windshield member 3 together. Furthermore, when fixing the display unit 4 or other display components to the equipment case 1 by screwing them in, space is required for screw fastening, and even after fixing, empty space for the screw heads must be secured. As a result, the mounting area and mounting capacity within the equipment case 1 become smaller. In this respect, when the display unit 4 or other display components are held on the shield member 7 via the buffer member 8, as in this embodiment, there is no need to secure parts or space for fixing the display unit 4, which reduces costs, makes the overall equipment lighter, and allows for a larger mounting area. And by securing a larger mounting area, it becomes possible to make the circuit board 6 itself smaller, which contributes to the miniaturization of the entire electronic device such as the clock 100.

[0047] Although embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these embodiments, and various modifications are possible without departing from the spirit of the invention.

[0048] For example, this embodiment illustrates a case where the electronic clock is clock 100, and the holding structure for holding the display unit, such as the display unit 4, is mounted on clock 100. However, the devices to which the holding structure for holding the display unit can be applied are not limited to this. For example, it can be widely applied to electronic devices that display various types of data, such as wearable devices like smartwatches and sports watches, heart rate monitors and blood pressure monitors that display biometric information such as heart rate and blood flow in addition to the time, and devices that display environmental information such as temperature and atmospheric pressure.

[0049] Although several embodiments of the present invention have been described above, the scope of the present invention is not limited to the embodiments described above, but includes the scope of the invention as described in the claims and its equivalents. [Explanation of symbols]
