Description

[Technical Field]

[0001] The present invention relates to an electronic device equipped with a detection device and a light emitting device. [Background technology]

[0002] Electronic devices such as laptops and smartphones are equipped with camera units. In many electronic devices equipped with camera units, the opening in the frame member opposite the lens of the camera unit is always open, allowing images to be taken at all times. In such cases, if the user does not properly manage virus protection, a malicious third party may take over the device and operate the camera unit. This can lead to problems such as personal information being leaked onto the network via the camera unit.

[0003] As one of the countermeasures for such a problem, for example, Patent Document 1 describes an opening / closing device (shutter device) that can be used for electronic devices equipped with a camera unit. The opening / closing device of Patent Document 1 has a structure in which the lens that forms the camera unit is physically blocked by a shutter, which allows a legitimate user of the electronic device to visually check whether the lens is blocked by the opening / closing device, and ultimately allows the user to confirm the inoperative state of the camera unit and feel secure. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] US Patent Application Publication No. 2020 / 0249415 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, electronic devices may be equipped with a light receiving sensor, a light emitting device, and the like in addition to a camera unit. However, it is difficult for a user to distinguish from the appearance alone that sensors other than a camera unit are devices that do not photograph the user. In other words, the user may mistake a sensor other than a camera unit for a camera unit. In this case, even if the camera unit is covered with an opening / closing device, the user may feel uneasy that they may be unintentionally photographed.

[0006] Furthermore, as electronic devices become smaller, the space available for mounting a camera unit including an opening / closing device also becomes smaller, and the opening / closing device described in Patent Document 1 faces limitations in its ability to accommodate the miniaturization of electronic devices. Specifically, the opening / closing device described in Patent Document 1 has a base that is provided over the entire longitudinal length of the device, and a cap is attached to the base. In particular, the base is formed in a substantially rectangular parallelepiped shape, and its volume is large, occupying most of the opening / closing device. This has been an obstacle to miniaturization of the entire opening / closing device.

[0007] A first object of the present invention is to provide an electronic device that can give a user a sense of security that no image is being taken of the user.

[0008] A second object of the present invention is to provide an electronic device equipped with a small opening and closing device that can be mounted even in a limited space. [Means for solving the problem]

[0009] In one aspect of the present invention, an electronic device comprises a hollow frame member, at least one of a detection device and a light-emitting device housed in the frame member and facing an opening provided in the frame member, and an opening / closing device housed in the frame member and opening and closing the opening, wherein the opening / closing device comprises blade members that open and close the opening, an actuator that moves the blade members back and forth, a base member that holds the actuator and is attached to a mounting surface provided on the frame member, and a cover member that is arranged to cover the blade members, has one longitudinal side attached to the base member and the other longitudinal side supported by the mounting surface. [Effects of the Invention]

[0010] According to the present invention, the detection device and the light emitting device are covered by the blade member, which gives the user a sense of security that no image is being taken of them.

[0011] In addition, the base member is attached to the mounting surface of the frame member, one longitudinal side of the cover member is attached to the base member, and the other longitudinal side of the cover member is supported on the mounting surface of the frame member. This eliminates the need to extend the base member all the way to the other longitudinal side of the cover member, making it possible to shorten (miniaturize) the base member and further miniaturize the opening / closing device. Therefore, it is possible to improve the functionality and design of the electronic device by, for example, making the frame member that forms the electronic device thinner.

[0013] Hereinafter, the first embodiment of the present invention will be described in detail with reference to the drawings.

[0014] Figure 1 shows a schematic diagram of a notebook computer equipped with a camera unit, Figure 2 shows an oblique view of the camera unit of Figure 1, Figure 3 shows a cross-sectional view along line AA of Figure 2, Figure 4 shows an exploded oblique view of the camera unit of Figure 1, Figure 5A shows an oblique view of the actuator unit (front side), Figure 5B shows an oblique view of the actuator unit (back side), Figure 6A shows an explanatory diagram of the operation of the actuator unit (CLOSE), Figure 6B shows an explanatory diagram of the operation of the actuator unit (OPEN), Figure 7A shows an explanatory diagram of the operation of the blade member (OPEN), and Figure 7B shows an explanatory diagram of the operation of the blade member (CLOSE).

[0015] 1, a notebook computer (electronic device) 10 includes a keyboard section 13 having a plurality of keys 11 and a touchpad 12 that are operated by a user, and a display section 14 that displays operation information from the plurality of keys 11 and the touchpad 12, as well as images or videos on the Internet. The keyboard section 13 and the display section 14 are each formed in a substantially flat plate shape and can be opened and closed by folding relative to each other via hinges (not shown).

[0016] The display unit 14 includes a display 15 such as a liquid crystal color monitor, and a hollow frame member 16 that surrounds the display 15. The frame member 16 supports the periphery of the display 15 to protect it. The frame member 16 also houses a flexible substrate (not shown) that supplies a driving current to the display 15, as well as a camera unit 17 that can be used, for example, for online conferences. A small window (opening) 18 is provided in the frame member 16 at a location facing the camera unit 17. The small window 18 connects the inside and outside of the frame member 16, and a lens portion 21b (see FIGS. 2 and 3) of the camera unit 17 faces the small window 18. This allows a user to view the lens portion 21b through the small window 18.

[0017] 2 to 4, camera unit 17 housed in frame member 16 includes module board 19 fixed inside frame member 16, camera module (detection device) 20 attached (mounted) to module board 19, and blade opening / closing device (opening / closing device) 30 that opens and closes small window 18 (see FIG. 1) in frame member 16. Blade opening / closing device 30 is housed in frame member 16 of notebook computer 10 as camera unit 17, with blade opening / closing device 30 fixed to module board 19 on which camera module 20 is mounted. This provides notebook computer 10 with a camera function.

[0018] The module substrate 19 is a PCB (printed circuit board) and has a first surface (front surface) 19a and a second surface (back surface) 19b, each of which has printed thereon conductor wiring made of a thin film of brass or the like. The camera module 20 and the blade opening and closing device 30 are fixed to the first surface 19a of the module substrate 19. Specifically, the camera module 20 and the blade opening and closing device 30 are fixed to the first surface 19a with an adhesive or the like with high precision and firmness. Meanwhile, the second surface 19b of the module substrate 19 is fixed to the frame member 16 with an adhesive or the like with high precision and firmness. In this way, the module substrate 19 is fixed integrally to the frame member 16, and the first surface 19a of the module substrate 19 corresponds to the mounting surface in the present invention.

[0019] Camera module 20 includes lens unit 21, which has base 21a fixed to first surface 19a of module substrate 19 and lens portion 21b formed in a generally cylindrical shape. An imaging element (not shown) is housed inside base 21a, and a convex lens (not shown) is housed inside lens portion 21b. With the increasing sophistication of modern electronic devices, including notebook computer 10, high-resolution imaging elements are being adopted. Since imaging elements with higher resolutions tend to be larger, the camera module 20 inevitably becomes larger. Therefore, miniaturizing camera unit 17 has become an important requirement in the development of modern electronic devices.

[0020] Furthermore, fixing members 22 for fixing the lens unit 21 to the module substrate 19 are arranged on both sides of the base portion 21a in the longitudinal direction of the module substrate 19. The fixing members 22 are, for example, a resin adhesive.

[0021] As shown in Figures 2 to 4, the blade opening / closing device 30 includes a base member 31 attached (fixed) to the first surface 19a of the module board 19, an actuator unit (actuator) 40 held by the base member 31, a partition plate 32 placed on the base member 31, a cover member 50 covering the base member 31 and the camera module 20, and a blade member 33 movably arranged between the cover member 50 and the partition plate 32 and opening and closing the small window 18 of the frame member 16.

[0022] The base member 31 extends in the longitudinal direction of the module substrate 19 and is disposed alongside the camera module 20 in the longitudinal direction of the module substrate 19. The base member 31 is formed from a resin material such as plastic into a generally rectangular parallelepiped shape with a plurality of projections and recesses. An actuator accommodating recess 31a that accommodates the actuator unit 40 is provided on the side of the base member 31 opposite to the camera module 20 side in the longitudinal direction (one side in the longitudinal direction).

[0023] Furthermore, a partition plate 32 is placed on the camera module 20 side (the other side in the longitudinal direction) of the base member 31, and a partition plate support part 31b is provided to support the longitudinal center part of the partition plate 32. Furthermore, in the longitudinal direction of the base member 31, a lever accommodating recess 31c is provided between the actuator accommodating recess 31a and the partition plate support part 31b to accommodate the drive lever 47 of the actuator unit 40 so that it can swing freely.

[0024] Here, the depth dimensions of the actuator accommodating recess 31a, the partition plate support portion 31b, and the lever accommodating recess 31c in the thickness direction of the module substrate 19 gradually become deeper in a stepped manner in the order of partition plate support portion 31b, lever accommodating recess 31c, and actuator accommodating recess 31a.

[0025] 3 and 4, a total of three grappling claws 31d (only two are shown in the figures) are integrally provided around the periphery of the base member 31 so as to protrude outward from the base member 31. These grappling claws 31d have a substantially triangular cross section, and each grappling claw 31d is adapted to be hooked onto an engaging portion 51c provided on the cover member 50. In other words, a snap fit is formed by the grappling claws 31d and the engaging portion 51c. The cover member 50 and the base member 31 have a total of three engaging portions, and the cover member 50 is firmly fixed to the base member 31 without any rattle.

[0026] The actuator accommodating recess 31a is integrally provided with a positioning protrusion 31e that is inserted into an insertion hole 42a (see FIGS. 5A and 5B) provided in the actuator unit 40 and that positions the actuator unit 40 relative to the actuator accommodating recess 31a. This allows the actuator unit 40 to be fixed inside the actuator accommodating recess 31a without rattle. This makes it possible to efficiently transmit the driving force of the actuator unit 40 to the blade members 33.

[0027] Furthermore, a pair of guide protrusions 31f are integrally formed on the partition plate support portion 31b so as to protrude in the thickness direction of the module substrate 19. These guide protrusions 31f face each other in the width direction (short direction) that intersects with the longitudinal direction of the module substrate 19, and blade members 33 are slidably provided between the pair of guide protrusions 31f while being guided by the respective guide protrusions 31f. This allows the blade members 33 to move straight in the longitudinal direction without vibrating in the short direction of the module substrate 19. This reduces the load on the actuator unit 40, and prevents malfunctions and the like caused by insufficient torque of the actuator unit 40.

[0028] Furthermore, a support pin 31g is integrally provided in the lever accommodating recess 31c to pivotally support the drive lever 47 of the actuator unit 40. This allows the drive lever 47 to pivot freely around the support pin 31g inside the lever accommodating recess 31c.

[0029] The actuator unit 40 is a drive source that reciprocates the blade members 33 in the longitudinal direction of the module substrate 19. As shown in FIGS. 5A and 5B, the actuator unit 40 includes a metal (magnetic) yoke 41 formed in a generally U-shape. The yoke 41 has a first arm 41a and a second arm 41b. The first arm 41a is fixed to a coil bobbin 42 made of a resin material (non-magnetic material) such as plastic. A coil (copper wire) 43 is wound around the first arm 41a via the coil bobbin 42 with a predetermined number of turns. The coil bobbin 42 is provided with a first connection terminal T1 and a second connection terminal T2 made of a conductor such as brass. One ends of the first and second connection terminals T1 and T2 are electrically connected to both ends of the coil 43, respectively, and the other ends of the first and second connection terminals T1 and T2 are electrically connected to the module substrate 19 via a flexible substrate 44 (see FIGS. 4, 7A, and 7B).

[0030] As a result, by switching the direction of the drive current flowing through coil 43 between the forward and reverse directions, first arm 41a, which is a magnetic body, is magnetized to a "north pole" or "south pole." On the other hand, second arm 41b, which is a magnetic body, becomes a "south pole" when first arm 41a is magnetized to a "north pole," and becomes a "north pole" when first arm 41a is magnetized to a "south pole" (see FIGS. 6A and 6B). As a result, magnetic lever 45, which forms actuator unit 40, swings in response to the switching of the polarities of first and second arms 41a and 41b.

[0031] Here, the coil bobbin 42 is provided with an insertion hole 42a for positioning the actuator unit 40 in the actuator accommodating recess 31a (see FIGS. 3 and 4) of the base member 31. That is, the positioning protrusion 31e (see FIG. 4) of the base member 31 is adapted to be inserted into the insertion hole 42a.

[0032] The magnetic lever 45 that forms the actuator unit 40 is supported so as to be able to swing freely on a swing shaft 31h (see FIG. 3) that is integrally provided in the actuator accommodating recess 31a that forms the base member 31. When the actuator unit 40 is assembled in the actuator accommodating recess 31a, the magnetic lever 45 is disposed between the first arm 41a and the second arm 41b.

[0033] The magnetic lever 45 is made of a resin material such as plastic, and as shown in FIGS. 6A and 6B, includes an annular lever body 45a and a drive pawl 45b with a fork-shaped tip. The forked portion of the drive pawl 45b is adapted to receive an input-side protrusion 47b (see FIG. 5B) of the drive lever 47. An annular rotor magnet 46 is fixed to the lever body 45a so as to be coaxial with the lever body 45a. The rotor magnet 46 is disposed between the first arm 41a and the second arm 41b so as to be able to swing freely. The rotor magnet 46 is a so-called plastic magnet, which can be molded with high precision and is not brittle, eliminating the risk of chipping.

[0034] 5B, 6A, and 6B, the rotor magnet 46 is integrally provided with magnet protrusions 46a that protrude radially outward. The rotor magnet 46 is magnetized with "north poles" and "south poles" at 180-degree intervals in the circumferential direction. The magnet protrusions 46a are "north poles" and protrude toward the drive claws 45b. As a result, the magnet protrusions 46a are attracted to or repelled by the first and second arms 41a and 41b, respectively, depending on the polarity of the first and second arms 41a and 41b.

[0035] The first and second arms 41a and 41b are magnetized to a "north pole" or "south pole" by switching the direction of the drive current flowing through the coil 43 between forward and reverse, generating an attractive force and a repulsive force. However, when the coil 43 is de-energized, the first and second arms 41a and 41b become simply metallic (magnetic). Therefore, for example, after a drive current is applied to the coil 43 to attract the magnet protrusion 46a to the first arm 41a, if the supply of the drive current to the coil 43 is stopped (de-energized), the state is maintained (de-energized state). This is because the magnetic force of the magnet protrusion 46a attracts the de-polarized magnetic first arm 41a. Therefore, since it is only necessary to temporarily apply a drive current to the coil 43, power consumption can be reduced.

[0036] 5A and 5B, the actuator unit 40 includes a drive lever 47 made of a resin material such as plastic and formed in a generally L-shape. The drive lever 47 is provided between the magnet lever 45 and the blade member 33, which is the driven object, and has the function of converting the swinging motion of the magnet lever 45 into the linear motion of the blade member 33. The drive lever 47 includes a lever body 47a formed in a generally L-shape, and one longitudinal side of the lever body 47a is provided with an input-side protrusion 47b that fits into the split portion of the drive claw 45b. The other longitudinal side of the lever body 47a is provided with an output-side protrusion 47c that fits into the inclined hole 33c (see FIG. 4) of the blade member 33.

[0037] In addition, a hole 47d is provided between the input-side protrusion 47b and the output-side protrusion 47c in the longitudinal direction of the lever body 47a. The hole 47d is supported so as to be swingable by a support pin 31g (see FIG. 4) of the base member 31. As a result, when the magnetic lever 45 swings around the swing shaft 31h (see FIG. 3), the drive lever 47 swings around the support pin 31g.

[0038] As shown in Fig. 4, the partition plate 32 is formed into a long plate shape by pressing a thin metal plate or the like, and extends over the entire longitudinal length of the blade opening / closing device 30. One longitudinal side (the left side in the figure) of the partition plate 32 is fixed (attached) to the base member 31, and the other longitudinal side (the right side in the figure) of the partition plate 32 is fixed (attached) to the cover member 50. A first opening 32a is provided on the other longitudinal side of the partition plate 32, and the first opening 32a penetrates the partition plate 32 in its plate thickness direction. The center portion of the first opening 32a is positioned on the optical axis P1 of the lens unit 21 and faces the small window 18 (see Fig. 1) provided in the frame member 16 of the notebook computer 10.

[0039] As a result, the lens unit 21 faces the small window 18, and light enters the lens unit 21 through the small window 18. In other words, the first opening 32a of the partition plate 32 functions as an aperture that determines the amount of light that enters the lens unit 21. For this reason, the partition plate 32 is also called an aperture plate. Here, the partition plate 32 can be omitted, in which case the second opening 51h of the cover member 50 functions as the aperture.

[0040] One longitudinal side of the partition plate 32 is provided with a pair of first holes 32b penetrating the partition plate 32 in the thickness direction. A positioning protrusion 31e is inserted into one of these first holes 32b. A protrusion 42b provided on the coil bobbin 42 of the actuator unit 40 is inserted into the other first hole 32b. This allows the one longitudinal side of the partition plate 32 to be fixed to both the base member 31 and the coil bobbin 42 with high precision and without rattle. This allows the blade members 33 driven by the actuator unit 40 to move smoothly relative to the partition plate 32.

[0041] Here, a first arc-shaped hole 32c is provided between the other first hole portion 32b and the first opening 32a in the longitudinal direction of the partition plate 32. The first arc-shaped hole 32c also penetrates the partition plate 32 in the thickness direction, and an output-side protrusion 47c (see FIG. 5A) of the drive lever 47 is movably provided inside the first arc-shaped hole 32c. The tip end (upper side in FIG. 4) of the output-side protrusion 47c extends beyond the partition plate 32 and reaches the blade member 33 disposed between the partition plate 32 and the cover member 50. The output-side protrusion 47c is not in contact with the partition plate 32. This reduces the load on the actuator unit 40.

[0042] Furthermore, a support protrusion 32d that is supported by a support hole 51f of the cover member 50 is integrally provided on the other longitudinal side of the partition plate 32 relative to the first opening 32a (the right side in FIG. 4). This support protrusion 32d protrudes toward the other longitudinal side of the partition plate 32 so as to be narrower than the width of the partition plate 32. This allows the support protrusion 32d to be inserted from the longitudinal direction of the partition plate 32 into the narrow support hole 51f provided in the cover member 50. The support hole 51f of the cover member 50 supports a back surface 32e of the support protrusion 32d (the back surface 32e of the partition plate 32). Meanwhile, the front surface 32f of the partition plate 32 is supported by a partition plate pressing protrusion 51g provided on the cover member 50.

[0043] As a result, a blade chamber RM (see FIG. 3) that movably houses the blade member 33 is formed between the partition plate 32 and the cover member 50. That is, the partition plate 32 forms the blade chamber RM together with the cover member 50. Therefore, the blade member 33 can move smoothly inside the blade chamber RM. This also reduces the load on the actuator unit 40.

[0044] 4, the blade members 33 are thin plates made of a resin material such as plastic, and the length dimension in the longitudinal direction thereof is approximately half the length dimension of the partition plate 32. In this way, by making the partition plate 32 out of metal and the blade members 33 out of resin, the movement of the blade members 33 relative to the partition plate 32 is made smooth. This reduces the load on the actuator unit 40, and prevents the actuator unit 40 from burning out, etc.

[0045] On one longitudinal side (left side in the figure) of the blade member 33, an elongated hole 33a is provided that extends straight in the longitudinal direction of the blade member 33 (the direction of movement of the blade member 33), and the elongated hole 33a penetrates the blade member 33 in the thickness direction. When the blade opening / closing device 30 is assembled, the protrusion 42b of the coil bobbin 42 fits freely into the elongated hole 33a. The elongated hole 33a guides the reciprocating movement (opening / closing operation) of the blade member 33, and also has the function of restricting the amount of movement of the blade member 33.

[0046] In this way, one longitudinal side of the blade member 33 is guided by the convex portion 42b, and the other longitudinal side of the blade member 33 is guided by the pair of guide protrusions 31f. Therefore, the blade member 33 can move straight in the longitudinal direction of the blade opening / closing device 30 with high precision.

[0047] Furthermore, a shutter portion 33b capable of blocking first opening 32a of partition plate 32 is provided on the other longitudinal side (right side in the figure) of blade member 33. Shutter portion 33b is capable of blocking the entire area of ​​first opening 32a as blade member 33 moves (see FIG. 7B). This blocks light from entering lens unit 21.

[0048] Furthermore, as shown in Fig. 4, in the longitudinal direction of the blade member 33, an inclined hole 33c is provided between the elongated hole 33a and the shutter portion 33b, which is inclined with respect to both the longitudinal and lateral directions of the blade member 33. The inclined hole 33c also penetrates the blade member 33 in the thickness direction. An output-side protrusion 47c (see Fig. 5A) of the drive lever 47 is slidably inserted inside the inclined hole 33c. As a result, as the drive lever 47 swings, the output-side protrusion 47c slides back and forth inside the inclined hole 33c, causing the blade member 33 to reciprocate in the longitudinal direction of the blade opening and closing device 30.

[0049] Here, because partition plate 32 is disposed between blade member 33 and drive lever 47, drive lever 47 and blade member 33 do not come into contact with each other. Therefore, the swinging motion of drive lever 47 does not adversely affect the linear motion of blade member 33. Furthermore, because partition plate 32 is also disposed between blade member 33 and lens unit 21, blade member 33 does not come into contact with lens unit 21. Therefore, scratches on lens unit 21 are effectively prevented.

[0050] 4, the cover member 50 is formed into a predetermined shape by pressing a metal plate or the like, and extends over the entire longitudinal direction of the blade opening and closing device 30, similar to the partition plate 32. One longitudinal side (the left side in the figure) of the cover member 50 is attached (fixed) to the base member 31, and the other longitudinal side (the right side in the figure) of the cover member 50 is supported by the first surface 19a of the module substrate 19. The cover member 50 has an elongated cover main body (main body portion) 51 formed in a plate shape, and the cover main body 51 covers the blade members 33. More specifically, the cover main body 51 has a first cover portion 51a that covers the actuator unit 40 side in the longitudinal direction of the blade opening and closing device 30, and a second cover portion 51b that covers the camera module 20 side in the longitudinal direction of the blade opening and closing device 30.

[0051] A total of three engaging portions 51c are integrally formed on the first cover portion 51a. These engaging portions 51c extend from the first cover portion 51a (cover main body 51) toward the base member 31 and are hooked onto three hooking claws 31d provided on the base member 31, respectively. This allows the cover member 50 to be firmly fixed to the base member 31.

[0052] In contrast, a leg 51d is integrally provided on the other longitudinal side of the second cover portion 51b, extending from the other longitudinal side of the cover body 51 toward the first surface 19a of the module substrate 19. The tip of the leg 51d is in contact with and supported by the first surface 19a of the module substrate 19. A pair of reinforcing portions 51e (see FIGS. 7A and 7B) bent in the longitudinal direction of the cover body 51 are integrally provided on the leg 51d, and the tip of each of these reinforcing portions 51e also contacts the first surface 19a of the module substrate 19. The leg 51d, including the pair of reinforcing portions 51e, has a substantially U-shaped cross section intersecting the optical axis P1. This increases the rigidity of the leg 51d and prevents the leg 51d from tipping outward (toward the opposite side from the camera module 20). This ensures sufficient rigidity of the second cover portion 51b in the direction of the optical axis P1.

[0053] Furthermore, a support hole 51f cut out in a substantially rectangular shape is provided on the base end side of the leg portion 51d. The support hole 51f penetrates the cover member 50 in the plate thickness direction, and the support protrusion 32d of the partition plate 32 is adapted to fit inside the support hole 51f. Specifically, the support protrusion 32d is adapted to fit into the support hole 51f from one side in the longitudinal direction of the cover member 50 (see FIGS. 7A and 7B). As a result, the back surface 32e (see FIG. 3) of the partition plate 32 is supported by the support hole 51f, and movement or bending of the partition plate 32 toward the camera module 20 (lens unit 21) side is suppressed.

[0054] Furthermore, a partition plate pressing protrusion 51g is integrally provided on the other longitudinal side of the second cover portion 51b and in the vicinity of the leg portion 51d. The partition plate pressing protrusion 51g protrudes by a predetermined height toward the surface 32f of the partition plate 32, and is pressed against the surface 32f of the partition plate 32 with the support protrusions 32d inserted into the support holes 51f. As a result, the other longitudinal side of the partition plate 32 is fixed to the other longitudinal side of the cover member 50 without any rattle, and a blade chamber RM (see FIG. 3) is formed with high precision between the partition plate 32 and the cover member 50. The thickness dimension of the blade chamber RM in the direction of the optical axis P1 is determined by the protruding height of the partition plate pressing protrusion 51g.

[0055] Here, the support protrusions 32d inserted into the support holes 51f are firmly fixed to the cover member 50 by an adhesive (not shown) so as not to come out. At this time, a predetermined amount of adhesive is poured into the support holes 51f, and even if the amount of adhesive poured into the support holes 51f is large, it is blocked by the partition plate pressing protrusions 51g. Therefore, the adhesive does not flow into the blade chambers RM. This effectively prevents the occurrence of defective products, etc.

[0056] 4, a second opening 51h is provided in the second cover portion 51b (on the other longitudinal side of the cover body 51), and the second opening 51h penetrates the second cover portion 51b in the thickness direction. The center portion of the second opening 51h is positioned on the optical axis P1 of the lens unit 21 and faces a small window 18 (see FIG. 1) provided in the frame member 16 of the notebook computer 10.

[0057] Here, the second opening 51h of the cover member 50 has the same opening shape and opening area as the first opening 32a of the partition plate 32, and they are overlapped with each other in the direction of the optical axis P1. The shutter portion 33b of the blade member 33 is movable between the first opening 32a and the second opening 51h.

[0058] Furthermore, a pair of second holes 51k are provided in the first cover portion 51a (one longitudinal side of the cover member 50) that penetrate the cover body 51 in the plate thickness direction. The positioning protrusion 31e of the base member 31 is inserted into one of these second holes 51k. The protrusion 42b of the coil bobbin 42 is inserted into the other second hole 51k. As a result, the one longitudinal side of the cover member 50 supports both the base member 31 and the coil bobbin 42 with high precision and without rattle. This allows the blade members 33 driven by the actuator unit 40 to move smoothly inside the blade chamber RM.

[0059] Furthermore, a second arc-shaped hole 51m is provided in a portion of the first cover portion 51a closer to the second cover portion 51b, between the other second hole portion 51k and the second opening 51h. The second arc-shaped hole 51m also penetrates the cover body 51 in the plate thickness direction, and an output-side protrusion 47c (see FIG. 5A) of the drive lever 47 is movably provided inside the second arc-shaped hole 51m. The second arc-shaped hole 51m has the same shape as the first arc-shaped hole 32c of the partition plate 32, so that the output-side protrusion 47c is not in contact with the cover member 50. This reduces the load on the actuator unit 40.

[0060] Here, the cover member 50 is fixed to the base member 31 using the hook claw 31d and the engagement portion 51c, but this fixing structure is not limited to this, and the cover member 50 can also be fixed to the base member 31 using, for example, a fixing screw or the like.

[0061] In this way, by providing the leg 51d on the other longitudinal side of the cover member 50 and supporting the leg 51d on the first surface 19a of the module substrate 19, it is not necessary to support the other longitudinal side of the cover member 50 on the base member 31. In other words, it is no longer necessary to provide the base member 31 over the entire longitudinal area of ​​the cover member 50, and it is possible to shorten the base member 31. Furthermore, since the base member 31 can be shortened, it is also possible to employ a camera module 20 (see FIG. 3) equipped with a high-resolution image sensor (large) without increasing the size of the camera unit 17.

[0062] Next, the operation of blade opening / closing device 30 forming camera unit 17 formed as described above will be described in detail with reference to FIGS. 6A, 6B, 7A and 7B.

[0063] [OPEN → CLOSE] As shown in Fig. 7A, when the blade opening / closing device 30 is in the "OPEN" state and the power supply to the coil 43 is "OFF," the actuator unit 40 is in the state shown in Fig. 6A. Specifically, the magnet protrusion 46a attracts the first arm portion 41a of the yoke 41 by its magnetic force, that is, the magnet protrusion 46a is positioned near the first arm portion 41a. Therefore, the blade member 33 is held in the "OPEN" state as shown in Fig. 7A.

[0064] When a drive current is supplied to the coil 43 and the direction of the drive current flowing through the coil 43 is set to the "forward direction," the first arm 41a becomes the "north pole" and the second arm 41b becomes the "south pole," as shown in Fig. 6A. As a result, the magnetic protrusion 46a, which is magnetized to the "north pole," is repelled by the first arm 41a and attracted to the second arm 41b. Therefore, the magnetic lever 45 swings clockwise as shown by arrow R1 in the figure, and accordingly, the drive lever 47 swings counterclockwise as shown by arrow R2 in the figure.

[0065] As a result, output-side protrusion 47c of drive lever 47 moves to the position indicated by the dashed line in Fig. 6A (reaching the state shown in Fig. 6B). Therefore, output-side protrusion 47c, which was located on the shutter portion 33b side in the longitudinal direction of inclined hole 33c as shown in Fig. 7A, moves to the elongated hole 33a side in the longitudinal direction of inclined hole 33c as shown in Fig. 7B. Therefore, blade member 33 moves to the other longitudinal side of cover member 50 (toward leg portion 51d), and shutter portion 33b closes first opening 32a of partition plate 32 and covers lens portion 21b as shown in Fig. 7B.

[0066] As a result, light passing through second opening 51h of cover member 50 is blocked by shutter portion 33b of blade member 33 and does not reach lens portion 21b. Therefore, even if camera module 20 operates against the user's intention in this state, images or videos cannot be captured, and as a result, images or videos that the user does not intend to capture and are leaked onto the Internet are reliably prevented.

[0067] [CLOSE → OPEN] As shown in Fig. 7B, when the blade opening / closing device 30 is in the "CLOSE" state and the current to the coil 43 is "OFF," the actuator unit 40 is in the state shown in Fig. 6B. Specifically, the magnet protrusion 46a attracts the second arm 41b of the yoke 41 by its magnetic force, that is, the magnet protrusion 46a is positioned closer to the second arm 41b. Therefore, the blade member 33 is held in the "CLOSE" state as shown in Fig. 7B.

[0068] Then, when a drive current is supplied to the coil 43 and the direction of the drive current flowing through the coil 43 is reversed, the second arm 41b becomes the "north pole" and the first arm 41a becomes the "south pole," as shown in FIG. 6B. As a result, the magnetic protrusion 46a, which is magnetized to the "north pole," is repelled by the second arm 41b and attracted to the first arm 41a. Therefore, the magnetic lever 45 swings counterclockwise as shown by arrow R3 in the figure, and the drive lever 47 swings clockwise as shown by arrow R4 in the figure.

[0069] As a result, output-side protrusion 47c of drive lever 47 moves to the position indicated by the dashed line in Fig. 6B (resulting in the state shown in Fig. 6A). Therefore, as shown in Fig. 7B, output-side protrusion 47c, which was disposed on the side of elongated hole 33a in the longitudinal direction of inclined hole 33c, moves to the shutter portion 33b side in the longitudinal direction of inclined hole 33c, as shown in Fig. 7A. Therefore, blade member 33 moves to one side in the longitudinal direction of cover member 50 (toward flexible substrate 44), and shutter portion 33b opens first opening 32a of partition plate 32 and also opens lens portion 21b, as shown in Fig. 7A.

[0070] As a result, light passing through the second opening 51h of the cover member 50 reaches the lens unit 21b via the first opening 32a of the partition plate 32. Therefore, in this state, the user can operate the camera module 20 as intended to capture images or videos.

[0071] As described above in detail, according to this embodiment, camera module 20 is covered by blade member 33, giving the user a sense of security that no images are being taken. Furthermore, base member 31 is attached to first surface 19a of module substrate 19, one longitudinal side of cover member 50 is attached to base member 31, and the other longitudinal side of cover member 50 is supported by first surface 19a of module substrate 19. This eliminates the need to extend base member 31 all the way to the other longitudinal side of cover member 50, making it possible to shorten (downsize) base member 31 and further miniaturize blade opening / closing device 30. Therefore, it is possible to improve the functionality and design of notebook computer 10 by, for example, making frame member 16 that forms notebook computer 10 thinner.

[0072] Furthermore, according to the present embodiment, cover member 50 includes cover main body 51 that covers blade members 33, and legs 51d that extend from cover main body 51 toward first surface 19a of module substrate 19 and are supported by first surface 19a, and legs 51d are provided with a pair of reinforcing portions 51e that are bent in the longitudinal direction of cover main body 51. This increases the rigidity of legs 51d, preventing legs 51d from falling outward (toward the opposite side from camera module 20). In other words, the rigidity of second cover portion 51b in the direction of optical axis P1 can be sufficiently increased.

[0073] Next, a second embodiment of the present invention will be described in detail with reference to the drawings. Note that parts having the same functions as those in the first embodiment will be given the same reference numerals, and detailed description thereof will be omitted.

[0074] FIG. 8 is a perspective view showing a camera unit according to the second embodiment, and FIG. 9 is an exploded perspective view of the camera unit of FIG.

[0075] As shown in FIGS. 8 and 9, in camera unit 60 of embodiment 2, first camera module 61 and second camera module 62 are arranged side by side in the longitudinal direction of module substrate 19. Note that first and second camera modules 61, 62 both correspond to the detection device of the present invention. Accordingly, the length dimension of blade opening / closing device 30 in the longitudinal direction of module substrate 19 is also longer than that of camera unit 17 of embodiment 1 (see FIGS. 2 to 4). Specifically, the length dimensions of partition plate 32, blade members 33, and cover member 50 are longer. However, base member 31 and actuator unit 40 held thereon are the same as those of embodiment 1.

[0076] 9, a third opening 32g is provided between the first opening 32a and the first arc-shaped hole 32c in the longitudinal direction of the partition plate 32. Similar to the first opening 32a, the third opening 32g also penetrates the partition plate 32 in its thickness direction. The center of the third opening 32g is aligned with the optical axis P2 of the lens unit 62a of the second camera module 62. The center of another small window (not shown) provided in the frame member 16 of the notebook computer 10 is also aligned with the optical axis P2.

[0077] 9, blade opening 33d and another shutter section 33e are arranged side by side between shutter section 33b and inclined hole 33c in the longitudinal direction of blade member 33. Blade opening 33d is located on the shutter section 33b side, and another shutter section 33e is located on the inclined hole 33c side. When blade opening / closing device 30 is in the "OPEN" state, blade opening 33d is located on optical axis P2, thereby opening lens unit 62a. In contrast, when blade opening / closing device 30 is in the "CLOSE" state, another shutter section 33e is located on optical axis P2, thereby blocking lens unit 62a. The opening and closing operations of first and second camera modules 61 and 62 are synchronized by the reciprocating movement of blade member 33.

[0078] Furthermore, as shown in FIG. 9, another partition plate pressing protrusion 51n and a fourth opening 51p are arranged side by side between the second opening 51h and the second arc-shaped hole 51m in the longitudinal direction of the cover member 50. The other partition plate pressing protrusion 51n is disposed on the second opening 51h side, and the fourth opening 51p is disposed on the second arc-shaped hole 51m side. The other partition plate pressing protrusion 51n protrudes beyond the blade opening 33d of the blade member 33 and is pressed against the surface 32f between the first opening 32a and the third opening 32g of the partition plate 32. As a result, the blade chamber RM (see FIG. 3) is formed with high precision between the partition plate 32 and the cover member 50 in this portion (the portion of the fourth opening 51p). The protruding height of the other partition plate pressing protrusion 51n is the same as the protruding height of the partition plate pressing protrusion 51g. The center portion of the fourth opening 51p is located on the optical axis P2.

[0079] Furthermore, as shown in FIG. 9 , a pair of reinforcing columns 51s are provided in the longitudinal direction of the cover member 50 between a pair of engaging portions 51c and legs 51d that are arranged opposite each other in the width direction of the cover member 50. Like the pair of engaging portions 51c, these reinforcing columns 51s are also arranged opposite each other in the width direction of the cover member 50, and like the engaging portions 51c and legs 51d, they extend toward the first surface 19a of the module substrate 19. The distal ends of the pair of reinforcing columns 51s are supported in contact with the first surface 19a, as shown in FIG. 8 . Each reinforcing column 51s is integrally provided with a recess 51t (only one of which is shown in the figure) that is recessed toward the other reinforcing column 51s, thereby ensuring sufficient strength of each reinforcing column 51s. Therefore, even if a pressing force acts on the cover member 50 from the direction of the optical axes P1 and P2, the cover member 50 is effectively prevented from being distorted, which would disable the blade members 33.

[0080] Here, in the second embodiment, as described above, the notebook computer 10 (see FIG. 1) is described as an example, which is equipped with a first camera module 61 and a second camera module 62 (both of which are detection devices in the present invention) and a blade opening / closing device 30 that opens and closes them. However, instead of this, the following [Modification 1] and [Modification 2] are also possible.

[0081] [Variation 1] In Modification 1 of Embodiment 2, an LED light 70 (see the symbol in parentheses in FIG. 9) is provided next to the first camera module 61. In this case, a pair of small windows 18 (only one is shown in the figure) are provided in the frame member 16 (see FIG. 1) of the notebook computer 10, with the first camera module 61 facing one of the small windows 18 and the LED light 70 facing the other small window 18. In Modification 1, even if the notebook computer 10 is used in a dark environment, it is possible to brightly illuminate the user, making it possible to hold online conferences and the like while providing clear images. Here, the LED light 70 corresponds to the light-emitting device in the present invention.

[0082] [Variation 2] In addition, in Modification 2 of Embodiment 2, instead of the first and second camera modules 61, 62, an LED light 70 and another LED light 80 (see the symbols in parentheses in FIG. 9) are provided side by side. In this case, as in Modification 1 described above, a pair of small windows 18 are provided in the frame member 16 of the notebook computer 10, and the LED light 70 and another LED light 80 face each of the small windows 18. In Modification 2, the user can easily grasp the operating status of the notebook computer 10, for example, whether or not it is in a state of communication with the network and whether or not the built-in battery has sufficient power remaining. Here, the LED light 80 also corresponds to the light-emitting device of the present invention.

[0083] These LED lights 70, 80 have a shape similar to a camera module (see FIG. 9), so by blocking the LED lights 70, 80 with the blade opening / closing device 30, it is possible to give the user a sense of security that no images are being taken.

[0084] Embodiment 2 including Modifications 1 and 2 formed as described above can also achieve the same effects as those of the above-described Embodiment 1. In addition, Embodiment 2 can realize a pair of camera modules (detection devices), a pair of LED lights (light-emitting devices), and a combination of a camera module and an LED light (detection device and light-emitting device), which in turn makes it possible to easily accommodate the increasing variety of electronic devices including the notebook computer 10.

[0085] Next, a third embodiment of the present invention will be described in detail with reference to the drawings. Note that parts having the same functions as those in the first embodiment will be given the same reference numerals, and detailed description thereof will be omitted.

[0086] FIG. 10 is an exploded perspective view showing the camera unit of the third embodiment, FIG. 11A is an explanatory diagram of the operation of the photoreflector (OPEN), and FIG. 11B is an explanatory diagram of the operation of the photoreflector (CLOSE).

[0087] 10, 11A, and 11B, the camera unit 90 of the third embodiment has a base member 91 with a different shape than that of the first embodiment. Specifically, a photoreflector accommodating recess 91a is provided on one longitudinal side (the left side in the drawings) of the base member 91. Therefore, the length of the base member 91 in the longitudinal direction of the module substrate 19 is longer than that of the base member 31 of the first embodiment (see FIG. 2). Specifically, the photoreflector accommodating recess 91a is located on the opposite side of the actuator accommodating recess 31a from the lever accommodating recess 31c.

[0088] A photoreflector 92 is housed inside the photoreflector housing recess 91a. As shown by the dashed arrow in Fig. 11B, the photoreflector 92 irradiates infrared light toward the cover member 50 (see Fig. 10) and receives the infrared light it has irradiated, thereby detecting whether or not there is an obstacle in the direction of irradiation (upper side in the figure) of the photoreflector 92. A drive current for the photoreflector 92 is supplied from the module substrate 19 via the flexible substrate 44.

[0089] 10, 11A, and 11B, a sensor cover 33f is integrally provided on one longitudinal side (left side in the figures) of the blade member 33, and is capable of shielding the photoreflector 92 in accordance with the reciprocating movement of the blade member 33. As shown in FIG. 11A, the sensor cover 33f shields the photoreflector 92 when the blade opening / closing device 30 is in the "OPEN" state, and as shown in FIG. 11B, the sensor cover 33f exposes the photoreflector 92 when the blade opening / closing device 30 is in the "CLOSE" state. The portion of the cover member 50 facing the photoreflector 92 is colored black (not shown) and is designed to absorb most of the infrared light emitted from the photoreflector 92. Therefore, when the blade opening / closing device 30 is in the "CLOSE" state (see FIG. 11B), the amount of light received by the photoreflector 92 is reduced.

[0090] In contrast, the portion of the sensor cover 33f facing the photoreflector 92 is red (not shown), the same color as the infrared light, and is configured to reflect most of the infrared light emitted from the photoreflector 92. Therefore, when the blade opening / closing device 30 is in the "OPEN" state (see FIG. 11A), a large amount of light is received by the photoreflector 92. In this way, by detecting the difference in light intensity between the "OPEN" state and the "CLOSE" state, it is possible to detect whether the blade opening / closing device 30 is in the "OPEN" state or the "CLOSE" state.

[0091] 10, 11A, and 11B, the increased length of blade member 33 requires some measure to allow blade member 33 to reciprocate smoothly without wobbling. Therefore, in this embodiment, another elongated hole 33g similar to elongated hole 33a is provided between sensor cover 33f and elongated hole 33a in the longitudinal direction of blade member 33, and positioning protrusion 31e is slidably inserted into the other elongated hole 33g. As a result, one longitudinal side of blade member 33 is guided by positioning protrusion 31e, allowing the entire blade member 33 to reciprocate smoothly without wobbling.

[0092] Furthermore, since base member 91 is longer on one side in the longitudinal direction, an insertion protrusion 91b is provided near photoreflector accommodating recess 91a, which is inserted into and fixed to third hole 51v (see FIG. 10) provided in cover member 50. This makes it possible to align the entire longitudinal area of ​​cover member 50 straight along the longitudinal direction of module substrate 19. In this way, in the third embodiment, by providing photoreflector accommodating recess 91a and photoreflector 92 accommodated therein, the length dimensions of both blade members 33 and cover member 50 are increased.

[0093] The third embodiment configured as described above can also achieve the same effects as those of the first embodiment. In addition, the third embodiment is provided with photoreflector 92 that can detect the open / closed state of blade 33, so that whether blade 33 is in the "OPEN" state or the "CLOSE" state can be fed back to notebook computer 10, thereby enabling accurate management of the operating state of blade opening / closing device 30.

[0094] The present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present invention. For example, in the above-described embodiments, the electronic device is a notebook computer 10, but the present invention is not limited to this and can also be applied to smartphones, tablet terminals, etc.

[0095] Furthermore, the camera module 20, first camera module 61, and second camera module 62 as the detection device may be any type of camera, such as an infrared camera or an image capturing camera controlled via a USB connection. Furthermore, the detection device may be a light-receiving sensor used to automatically adjust the illumination of the backlight of a display forming an electronic device, or a temperature sensor installed in an electronic device installed in a storefront to measure the body temperature of a customer. In short, any type of detection device may be used as long as it can incorporate information external to the electronic device into the electronic device. Furthermore, in the above-described first embodiment, instead of the camera module 20 as the detection device, a light-emitting device such as an LED light that illuminates the keyboard unit 13 (see FIG. 1) may be used. This allows the shutter opening / closing device 30 to block light-emitting elements such as LED lights that have a shape similar to the camera module, giving the user peace of mind that their image is not being taken.

[0096] Furthermore, to clearly indicate to the outside that the blade member 33 is in the "CLOSE" state, the word "closed" can be written on the surface of the shutter portion 33b (33e) or the surface of the shutter portion 33b (33e) can be colored a highly visible red or the like. This makes it easy for the outside to recognize that the user is protected from unintended capture of images or videos.

[0097] In addition, the material, shape, dimensions, number, installation location, etc. of each component in each of the above-mentioned embodiments are arbitrary as long as they can achieve the present invention, and are not limited to each of the above-mentioned embodiments.
