Terminal apparatus
View Patent ↗A terminal apparatus includes a body and a display that is rotatably joined to the body by a swivel shaft. Hinge mechanisms that open and close the display with respect to the body are provided on both sides of the swivel shaft. The hinge mechanisms are connected to the ground of the display and parts of the hinge mechanisms protrude from the lower edge of the display. Metal components that are connected to the ground of the body and support and make conductive contact with the protrusions of the hinge mechanisms are provided on the body. Since the grounds of the display and the body are connected by both the swivel shaft and the hinge mechanisms, a potential difference between the grounds of the body and the display is reduced compared to when the grounds are connected only via the swivel shaft.
1. A terminal apparatus comprising:
a body;
a display connected to the body by a swivel shaft;
conductive components that are provided at both ends in a length direction of a side surface of the display facing the body, are connected to a ground of the display, and are exposed from the side surface; and
support components that are conductive, are provided on an upper cover of the body, are connected to a ground of the body, and support the display from the body in a state where the support components are in conductive contact with the conductive components of the display,
wherein the swivel shaft includes a base portion, which is fixed to the body, and a rotational shaft, which is fixed to the display and is rotatable with respect to the base portion,
a hinge shaft is provided along the length direction of the side surface of the display on both sides of the rotational shaft in a direction that is perpendicular to an axis of the rotational shaft,
hinge mechanisms that open and close the display with respect to the body are provided at both ends of the hinge shaft, and
the conductive components are protrusions provided on brackets that attach the hinge mechanisms to the display.
2. The terminal apparatus according to claim 1 ,
wherein the upper cover is formed of a nonconductive material and the support components are metal components provided on a surface of the upper cover.
3. The terminal apparatus according to claim 2 ,
wherein surfaces of the metal components are located at a predetermined height above the surface of the upper cover.
4. The terminal apparatus according to claim 2 ,
wherein the side surface of the display facing the body is formed as a first circumferential surface,
the protrusions each have a second circumferential surface that is flush with the first circumferential surface and an extension that is continuous with the second circumferential surface, and
the metal components connect to and support the protrusions when the display is opened and closed with respect to the body using the hinge mechanisms.
5. The terminal apparatus according to claim 4 ,
wherein front ends of the protrusions are formed so as to press a surface of the metal components when the protrusions come into connective contact with the metal components.
6. The terminal apparatus according to claim 2 ,
wherein the side surface of the display facing the body is formed as a first circumferential surface,
the protrusions each have a second circumferential surface that protrudes slightly beyond the first circumferential surface and an extension that is continuous with the second circumferential surface, and are each located at a predetermined height above the side surface, and
the metal components become continuous with and support the protrusions when the display is opened and closed with respect to the body using the hinge mechanisms.
7. The terminal apparatus according to claim 1 ,
wherein permanent magnets are provided in the body inside the support components.
8. The terminal apparatus according to claim 7 ,
wherein an outer circumferential surface of the rotational shaft is a circumferential surface, and
the rotational shaft is capable of freely rotating with respect to the base portion of the swivel shaft.
9. The terminal apparatus according to claim 1 ,
wherein the upper cover is made of a conductive metal material, and
the support components are the upper cover.
10. The terminal apparatus according to claim 9 ,
wherein parts of the upper cover that face the conductive components are bulges that are raised by a predetermined height with respect to other parts of the upper cover.
11. The terminal apparatus according to claim 10 ,
wherein permanent magnets are provided in the body inside the bulges.
12. The terminal apparatus according to claim 1 ,
wherein at least one pair of parallel surfaces, which are parallel to an axis of the swivel shaft and have the axis in between, is formed in an outer circumferential surface of the rotational shaft, and
a pressing mechanism, which presses the parallel surfaces from both sides to fix an angle of the rotational shaft with respect to the base portion, is provided on an outside of the base portion of the swivel shaft.
