TERMINAL APPARATUS AND HINGE STRUCTURE
A terminal apparatus that includes a first housing, a second housing, and a hinge mechanism that slidably couples the first housing to the second housing in each of an open state and a closed state with respect to the second housing. The hinge mechanism includes a base portion and a movable portion, the movable portion being slidable with respect to the base portion in a direction which the first housing moves away from the second housing when the first housing transitions from the closed state to the open state with respect to the second housing.
1 . A terminal apparatus comprising:
a first housing;
a second housing; and
a hinge mechanism that slidably couples the first housing to the second housing in each of an open state and a closed state with respect to the second housing, wherein
the hinge mechanism includes a base portion and a movable portion, the movable portion being slidable with respect to the base portion in a direction which the first housing moves away from the second housing when the first housing transitions from the closed state to the open state with respect to the second housing.
2 . The terminal apparatus of claim 1 , wherein the base portion includes a retention portion that maintains the movable portion at a predetermined position after being moved in the direction away from the second housing.
3 . The terminal apparatus of claim 1 , wherein the movable portion is slidable a direction which the first housing moves toward the second housing when the first housing transitions from the open state to the closed state with respect to the second housing.
4 . The terminal apparatus of claim 3 , wherein the base portion includes a retention portion that maintains the movable portion at a predetermined position after being moved in the direction toward the second housing.
5 . The terminal apparatus of claim 1 , wherein the movable portion is a rod-shaped member attached to the first housing.
6 . The terminal apparatus of claim 5 , wherein the base portion is a cylinder-shaped member that has an internal space in which the rod-shaped member slides.
7 . The terminal apparatus of claim 6 , wherein the rod-shaped member includes a portion having a first diameter and a portion having a second diameter, which is larger than the first diameter.
8 . The terminal apparatus of claim 7 , wherein an outer periphery of the portion having the second diameter contacts an inner wall of the cylinder-shaped member.
9 . The terminal apparatus of claim 8 , wherein the cylinder-shaped member includes a projection that stops the portion having the second diameter of the rod-shaped member at a predetermined position after being moved in the direction away from the second housing.
10 . The terminal apparatus of claim 8 , wherein the cylinder-shaped member includes a projection that stops the portion having the second diameter of the rod-shaped member at a predetermined position after being moved in the direction toward the second housing.
11 . The terminal apparatus of claim 1 , wherein the base portion is rotatably connected to the second housing.
12 . The terminal apparatus of claim 11 , wherein the base portion includes a shaft-receiving portion projecting in a lateral direction from one end of the base portion.
13 . The terminal apparatus of claim 12 , wherein the shaft-receiving portion is coupled to a shaft disposed at a rear end portion of the second housing that extends in parallel with a rear side of the second housing.
14 . The terminal apparatus of claim 1 , wherein one end of the movable portion is connected to the first housing and another end of the movable portion includes a concave-convex portion.
15 . The terminal apparatus of claim 14 , further comprising:
a cam portion that is fixed to the second housing and engages with the convex-concave portion of the movable portion.
16 . The terminal apparatus of claim 15 , wherein the movable portion slides with the convex-concave portion engageably rotating with respect to the cam portion such that the movable portion slides with respect to the base portion in a direction which the first housing moves away from the second housing when the first housing transitions from the closed state to the open state with respect to the second housing.
17 . The terminal apparatus of claim 16 , wherein the base portion is a cylinder-shaped member that has an internal space in which the movable portion slides.
18 . The terminal apparatus of claim 17 , further comprising:
an elastic member that applies a force in an opposite direction to a direction in which the member projects from the cylinder-shaped member.
19 . The terminal apparatus of claim 18 , wherein the elastic member is located within the cylinder-shaped member, and surrounds a portion of the movable portion located within the cylinder-shaped member.
20 . The terminal apparatus of claim 19 , wherein the elastic member is in contact with an upper end of the cylinder-shaped member and is in contact with the concave-convex portion of the movable portion.
