Modes for Carrying Out the Invention

[0010] (First Embodiment) Hereinafter, a first embodiment of the opening / closing device of the present invention and an electronic device including the same will be described with reference to the drawings.

[0011] FIG. 1 is a perspective view of an electronic device 100 provided with an opening / closing device 1. The electronic device 100 includes a main body portion 101 and a lid portion 102. And the electronic device 100 is configured such that the lid portion 102 is connected to the main body portion 101 so as to be openable and closable by the opening / closing device 1. Examples of the electronic device 100 include OA devices such as scanners, fax machines, copiers, or multifunction devices, or rice cookers, etc. Note that the opening / closing device 1 of the present embodiment only needs to be able to open and close two members, and is not limited to electronic devices, and can also be applied to, for example, automobiles, toilet seats, furniture, etc.

[0012] FIG. 2 is a perspective view of the opening / closing device 1 in the open state. FIG. 3 is a perspective view of the opening / closing device 1 in the closed state. FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG. 2. FIG. 5 is a cross-sectional view taken along the line V-V of FIG. 3.

[0013] In the opening / closing device 1 of the present embodiment, a rotating member 20 is provided on a case member 10 via a rotating shaft member 30, and the rotating member 20 is configured to be rotatable about the rotating shaft member 30 as a fulcrum. In the present embodiment, the operation in which the rotating member 20 rotates about the rotating shaft member 30 as a fulcrum is referred to as an opening / closing operation. Also, the end portion of the rotating member 20 on the side opposite to the rotation fulcrum is referred to as the opening direction in the rotation direction of the rotating member 20, which is the direction away from the case member 10, and the direction approaching the case member 10 is referred to as the closing direction. The open state in FIG. 2 refers to the state in which the rotating member 20 has rotated completely in the opening direction. Also, the closed state in FIG. 3 refers to the state in which the rotating member 20 has rotated completely in the closing direction.

[0014] Note that in the opening / closing device 1, the case member 10 is attached to the main body portion 101 (see FIG. 1) of the electronic device 100, and the rotating member 20 is attached to the lid portion 102 of the electronic device 100. Thereby, the lid portion 102 of the electronic device 100 can rotate with respect to the main body portion 101.

[0015] In this embodiment, for convenience of explanation, it is assumed that the case member 10 and the rotating member 20 are arranged in the vertical direction, with the case member 10 on the lower side and the rotating member 20 on the upper side. Also, the directions orthogonal to each other and orthogonal to the vertical direction are defined as the front-rear direction and the left-right direction, respectively. When the opening / closing device 1 is in the open state, the longitudinal direction of the rotating member 20 is substantially along the vertical direction, and when it rotates in the closing direction, it falls forward in the front-rear direction. Note that these directions do not limit the usage state of the opening / closing device 1.

[0016] (Configuration of the opening / closing device 1) The opening / closing device 1 includes a case member 10, a rotating member 20, a rotating shaft member 30, an elastic member 40, a slide member 50, and a conductive member 60.

[0017] The case member 10 is a cylindrical member extending along the vertical direction and is formed of an insulating material such as resin, for example. The upper end of the case member 10 is open, and the lower end is closed. The case member 10 has a pair of side wall portions 10A facing each other in the left-right direction at the open upper end. A rotating shaft member 30 is provided on the pair of side wall portions 10A.

[0018] The rotating shaft member 30 is formed of, for example, iron and has conductivity. The rotating shaft member 30 has a cylindrical shape extending along the left-right direction. At least the left end of the rotating shaft member 30 protrudes outward from the side wall portion 10A of the case member 10. In this embodiment, a second connecting member 63 of the conductive member 60 described later is provided at the left end of the rotating shaft member 30 protruding from the side wall portion 10A.

[0019] The rotating member 20 is formed of an insulating material such as resin, for example, and is rotatably connected to the case member 10 via the rotating shaft member 30. The rotating member 20 has a cam portion 21. When the opening / closing device 1 rotates from the open state in the closing direction, the cam portion 21 presses the slide member 50 described later downward.

[0020] The elastic member 40 is housed in the case member 10 and presses the rotating member 20 that rotates in the closing direction in the opening direction by an elastic force. The elastic member 40 is, for example, a coil spring, and is housed in the case member 10 in a posture that expands and contracts in the vertical direction.

[0021] The slide member 50 is a cylindrical member with one end open and the other end closed. The slide member 50 is housed in the case member 10 so as to be movable along the vertical direction with the open end facing downward. The slide member 50 houses the upper end portion of the elastic member 40 inside and is pressed upward by the elastic force of the elastic member 40.

[0022] The slide member 50 is provided with a pressure receiving portion 51 that engages with the cam portion 21 of the rotating member 20 on the upper surface of the closed end portion. The slide member 50 moves in the vertical direction by the pressing force from the cam portion 21 of the rotating member 20 against the pressure receiving portion 51 and the elastic force of the elastic member 40. Specifically, when the rotating member 20 rotates in the closing direction in the open state of the opening / closing device 1 shown in FIGS. 2 and 4, the slide member 50 moves downward as the pressure receiving portion 51 is pressed by the cam portion 21. Also, when the rotating member 20 rotates in the opening direction in the closed state of the opening / closing device 1 shown in FIGS. 3 and 5, the slide member 50 moves upward as it is pressed by the elastic force of the elastic member 40. The pressure receiving portion 51 may be provided integrally with the slide member 50, or a cylindrical member made of metal may be provided on the upper surface of the slide member 50.

[0023] (Regarding the conductive member 60) The conductive member 60 is a member that electrically connects between the main body portion 101 and the lid portion 102 of the electronic device 100. The conductive member 60 is supported by the rotary shaft member 30 so as to be electrically conductive with the rotary shaft member 30. FIG. 6 is a perspective view of the conductive member 60. In FIG. 6, for convenience of explanation, the rotary shaft member 30 is also shown. The conductive member 60 has a first connection member 61, an auxiliary member 62, and a second connection member 63.

[0024] The first connection member 61 is a member for electrically connecting to the main body 101 (see FIG. 1) of the electronic device 100 where the opening / closing device 1 is provided. The first connection member 61 is formed from a strip-shaped sheet metal and has a pair of insertion portions 611, a pair of plate-shaped portions 612, and a connecting portion 613.

[0025] The pair of plate-shaped portions 612 are strip-shaped sheet metals that face each other in the left-right direction and extend along the up-down direction. As shown in FIGS. 2 and 3, the pair of plate-shaped portions 612 are arranged along the outer side of the side surface of the case member 10.

[0026] The connecting portion 613 is a strip-shaped sheet metal that extends along the left-right direction and connects the pair of plate-shaped portions 612. As shown in FIGS. 4 and 5, the connecting portion 613 is arranged along the outer side of the bottom surface of the case member 10.

[0027] The pair of insertion portions 611 are plate-shaped sheet metals provided at the upper end portions of the pair of plate-shaped portions 612. The pair of insertion portions 611 penetrate in the left-right direction and have holes 611A into which the rotary shaft member 30 is inserted. The hole 611A of one of the pair of insertion portions 611 (the left insertion portion 611 in this embodiment) is formed in a keyhole shape composed of a circular shape and a rectangular shape when viewed from the left-right direction. The rotary shaft member 30 is inserted into the circular portion of the hole 611A. Near the hole 611A formed in the keyhole shape, two convex portions 611B protruding leftward are provided.

[0028] Note that the first connection member 61 may be formed by bending a single strip-shaped sheet metal, or may be formed by connecting different sheet metals by welding or the like. Since the first connection member 61 configured in this way is provided along the outer side of the side surface and the outer side of the bottom surface of the case member 10, the case member 10 will have its outer peripheral surface surrounded by the first connection member 61. That is, the first connection member 61 also functions as an auxiliary member of the case member 10. Note that the connecting portion 613 may be arranged inside the bottom surface of the case member 10.

[0029] The auxiliary member 62 is a sheet metal piece with a substantially circular shape and has a hole 621 penetrating in the thickness direction. The hole 621 is formed in a keyhole shape composed of a circular shape and a rectangular shape in a plan view. The rotary shaft member 30 is inserted into the circular portion of the hole 621. The auxiliary member 62 is disposed on the insertion portion 611 so that the keyhole-shaped hole 621 overlaps with the keyhole-shaped hole 611A of the insertion portion 611.

[0030] The auxiliary member 62 has a claw portion 622 formed in the rectangular portion of the keyhole-shaped hole 621. The claw portion 622 protrudes inside the circular portion so as to contact the rotary shaft member 30 inserted into the circular portion of the keyhole-shaped hole 621 and has elasticity along the axial direction of the rotary shaft member 30. Since the claw portion 622 exists in the circular portion of the hole 621 into which the rotary shaft member 30 is inserted, when the rotary shaft member 30 is inserted into this hole 621, it contacts the claw portion 622. Since the claw portion 622 has elasticity in the axial direction of the rotary shaft member 30, with the insertion of the rotary shaft member 30, after it bends in the insertion direction, it tries to return due to the elastic force and thus comes into close contact with the outer peripheral surface of the rotary shaft member 30. That is, the auxiliary member 62 is reliably electrically connected to the rotary shaft member 30 by the claw portion 622.

[0031] Note that the hole 611A of the insertion portion 611 that overlaps with the auxiliary member 62 is in a keyhole shape. And the claw portion 622 comes to be located in the rectangular portion of the hole 611A of the insertion portion 611. For this reason, when the claw portion 622 bends, the bending is not inhibited by the insertion portion 611.

[0032] As in this embodiment, by separately using the auxiliary member 62 having the claw portion 622, it is not necessary to process the first connection member 61, and it is also possible to ensure conduction between the first connection member 61 and the rotary shaft member 30 even for the existing first connection member 61. Note that the claw portion 622 may be provided in the hole 611A of the insertion portion 611. In this case, the auxiliary member 62 becomes unnecessary and the number of parts of the conductive member 60 can be reduced.

[0033] Further, the auxiliary member 62 has two small holes 623 provided near the hole 621. When the auxiliary member 62 is overlaid on the insertion portion 611, the convex portion 611B provided on the insertion portion 611 is inserted into the small holes 623. Thereby, the auxiliary member 62 is prevented from rotating with respect to the first connection member 61. The small holes 623 correspond to the "fitting portion" of the present invention.

[0034] Since the auxiliary member 62 arranged to overlap with the first connection member 61 is in surface contact with the first connection member 61 without rotating with respect to the first connection member 61, the electrical connection between the auxiliary member 62 and the first connection member 61 is surely ensured. Also, as described above, the electrical connection between the auxiliary member 62 and the rotating shaft member 30 is surely ensured. Therefore, the electrical connection between the first connection member 61 and the rotating shaft member 30 is surely ensured.

[0035] The second connection member 63 is a member for electrically connecting to the lid portion 102 (see FIG. 1) of the electronic device 100 where the opening and closing device 1 is provided. The second connection member 63 has a mounting portion 631 and a mounting portion 632, and a connection portion 633. The mounting portions 631 and 632 have the same configuration, the mounting portion 631 is mounted on the opening and closing device 1, and the mounting portion 632 is mounted on the electronic device 100. The mounting portions 631 and 632 have through holes 631A and 632A. The connection portion 633 electrically connects the mounting portions 631 and 632 to the electronic device 100. The connection portion 633 may be a flexible rod member or a cord.

[0036] The second connection member 63 is provided at the left end portion of the rotating shaft member 30 protruding from the side wall portion 10A, with the mounting portion 631. The rotating shaft member 30 has a cylindrical shape, and a screw groove (not shown) is formed on the inner peripheral surface at the left end portion thereof. The second connection member 63 is fixed to the rotating shaft member 30 by overlapping the through hole 631A of the mounting portion 631 with the opening of the rotating shaft member 30 and fastening with a screw 64.

[0037] The opening and closing device 1 configured as described above can be electrically connected between the main body 101 and the lid 102 of the electronic device 100 by connecting the conductor components in the main body 101 of the electronic device 100 to the first connection member 61 of the conductive member 60 and connecting the conductor components in the lid 102 of the electronic device 100 to the second connection member 63. By using the auxiliary member 62 having the claw portion 622, the conductive member 60 can surely establish an electrical connection between the first connection member 61 and the rotating shaft member 30. Since the first connection member 61 is disposed outside the side surface and the bottom surface of the case member 10, the degree of freedom in designing the wiring connected to the first connection member 61 in the main body 101 of the electronic device 100 is improved. That is, it becomes easy to make design changes on the main body 101 side of the electronic device 100 when wiring.

[0038] Further, since the first connection member 61 is disposed outside the case member 10, there is no need to secure a space for disposing the first connection member 61 inside the case member 10 where the elastic member 40 and the slide member 50 are disposed. That is, an increase in the size of the case member 10 can be suppressed.

[0039] (Modification of the First Embodiment) FIG. 7 is a perspective view showing an opening and closing device 1A according to a modification of the first embodiment. In the opening and closing device 1A shown in FIG. 7, the configuration of the conductive member 60 is different from that of the above-described embodiment. Specifically, the conductive member 60 of the modification does not have the second connection member 63, but has a third connection member 65. Hereinafter, the third connection member 65, which is this difference, will be described. Note that the rotating member 20 of the opening and closing device 1A shown in FIG. 7 has a different shape from that shown in the above-described embodiment, but the configuration is the same.

[0040] FIG. 8 is a view showing the third connection member 65 included in the conductive member 60. The third connection member 65 has a fixing portion 651 fixed to the rotating member 20 and a pair of insertion portions 652 that face each other in the left-right direction and into which the rotating shaft member 30 is inserted.

[0041] As shown in FIG. 8, the fixing portion 651 is disposed outside the upper surface of the rotating shaft member 30. Since the fixing portion 651 is disposed outside the rotating shaft member 30, the degree of freedom in designing the wiring connected to the third connecting member 65 in the lid portion 102 of the electronic device 100 is improved. That is, it becomes easy to change the design on the lid portion 102 side of the electronic device 100 when wiring.

[0042] Each of the pair of insertion portions 652 is provided with a hole 653 into which the rotating shaft member 30 is inserted. A claw portion 654 is also provided in the hole 653, similar to the claw portion 622 described with reference to FIG. 6. With this claw portion 654, the third connecting member 65 and the rotating shaft member 30 can be surely electrically connected. Note that the third connecting member 65 may be configured such that the claw portion 654 is not provided on the pair of insertion portions 652, and the auxiliary member 62 is provided on each of the pair of insertion portions 652, as in the above-described embodiment.

[0043] (Second Embodiment) Hereinafter, a second embodiment of the opening / closing device according to the present invention will be described. In this embodiment, the configuration of the conductive member is different from that of the first embodiment. Hereinafter, only the configuration different from that of the first embodiment will be described, and the description of the same configuration as that of the first embodiment will be omitted.

[0044] FIG. 9 is a perspective view of the conductive member 60 according to the second embodiment. The conductive member 60 includes a first connecting member 61, an auxiliary member 62, and a second connecting member 63 (see FIG. 6). FIG. 9 shows the insertion portion 611 of the first connecting member 61 and the auxiliary member 62 disposed thereon. The configuration of the first connecting member 61 other than the insertion portion 611 shown in FIG. 9 is the same as that of the first embodiment.

[0045] The insertion portion 611 of the present embodiment further has slits 611C and 611D in addition to the hole 611A and the two convex portions 611B. The slit 611C is formed by notching the edge of the sheet metal constituting the insertion portion 611. The slit 611D is formed by penetrating the sheet metal constituting the insertion portion 611 in the thickness direction. The slits 611C and 611D are provided so as to sandwich the hole 611A.

[0046] The auxiliary member 62 further has attachment pieces 66 and 67 in addition to the holes 621, the claw portions 622, and the two small holes 623 provided in the substantially circular sheet metal. The attachment pieces 66 and 67 are provided at positions sandwiching the hole 621 at the peripheral edge of the substantially circular sheet metal. The attachment pieces 66 and 67 are configured by bending a part of the edge of the sheet metal toward the insertion portion 611 side. In the auxiliary member 62, the bent portions of the attachment pieces 66 and 67 are press-fitted into the slits 611C and 611D provided in the insertion portion 611 and are arranged so as to overlap the insertion portion 611. Note that the slits 611C and 611D may be provided on the auxiliary member 62 side, and the attachment pieces 66 and 67 may be provided on the first connection member 61 side.

[0047] In this way, since the insertion portion 611 and the auxiliary member 62 are in close contact by press-fitting, the degree of close contact between the insertion portion 611 and the auxiliary member 62 is increased, and the resistance value of the connection portion between the insertion portion 611 and the auxiliary member 62 does not become unstable, and the insertion portion 611 and the auxiliary member 62 are surely electrically connected. Therefore, the electrical connection between the first connection member 61 and the rotating shaft member 30 is also surely ensured via the auxiliary member 62.

[0048] (Modification of the Second Embodiment) FIG. 10 is a perspective view of the conductive member 60 according to the modification of the second embodiment. In this modification, the first connection member 61 has the slit 611C described in FIG. 9 and a slit 611E formed by penetrating the connecting portion 613 in the thickness direction. The auxiliary member 62 is composed of a sheet metal having an L shape when viewed from the front-rear direction and is arranged so as to overlap the insertion portion 611, the plate-shaped portion 612, and the connecting portion 613 of the first connection member 61. Note that in FIG. 10, for the sake of explanation, a state in which the first connection member 61 and the auxiliary member 62 are separated is shown. The auxiliary member 62 has the attachment piece 66 described in FIG. 9 and an attachment piece 68 provided at the end portion on the side that contacts the connecting portion 613. The attachment piece 68 is configured by bending a part of the end portion toward the connecting portion 613 side.

[0049] The auxiliary member 62 is arranged such that the bent portions of the attachment pieces 66 and 68 are press-fitted and engaged with the slits 611C and 611E provided in the insertion portion 611, and are overlapped with the insertion portion 611, the plate-shaped portion 612, and the connecting portion 613. Even with this configuration, the resistance value at the connection portion between the insertion portion 611 and the auxiliary member 62 does not become unstable, and the insertion portion 611 and the auxiliary member 62 can be surely electrically connected. Note that the slit 611E may be provided in the plate-shaped portion 612, and the attachment piece 68 may be provided at a position where it can be inserted into the slit 611E.

[0050] (Other Modification Examples) In the above-described embodiment, in the first connection member 61 of the conductive member 60, the connecting portion 613 is configured to be arranged outside the bottom surface of the case member 10, but is not limited thereto. For example, the connecting portion 613 may be arranged along the side surface of the case member 10. Further, an auxiliary member 62 may be provided for each of the pair of insertion portions 611 included in the first connection member 61. Also, the configurations described in the first embodiment and the second embodiment may be appropriately combined. For example, in the first embodiment, the auxiliary member 62 may have the shape shown in FIG. 10.
