[0003] As a hinge member used in the folding type portable telephone, for example, Japanese Patent Application Laid-Open No. H8-317025,
A hinge member described in JP-A-8-65369 is known. The hinge member has a built-in pressure spring and has the function of automatically opening the lid and holding the lid in the closed state and the open state at the same time, and does not exert an axial force on the main body or the housing of the lid, so that deformation is caused. There was a merit that it could be prevented. The hinge member can be assembled independently, and the assembled hinge member can be assembled into a mobile phone simply by inserting the hinge member into the cavity of the housing.

Incidentally, such a hinge member has a casing attached to the main body, and a cam and a trace inserted into the casing. FIG. 8 shows the operation of the cam and the tracing unit in the conventional flip-type mobile phone. FIG. 8A shows the tracing unit 101 when the lid is closed.
Is pressed by the concave portion 102a of the cam 102.

When the lid is manually opened from this state, the cam 102 non-rotatably connected to the lid rotates with the lid, but the trace 101 non-rotatably attached to the main body does not rotate. Therefore, the trace portion 101 moves in the axial direction along the steep slope portion 102b of the cam 102 to reach the convex portion 102c (FIG. 8B).

If the opening angle further increases slightly, the trace portion 101 climbs over the convex portion 102c and proceeds to the gentle slope portion 102d. However, since the pressing force of the pressing means is acting on the trace portion 101, It slides down automatically to the next concave portion 102a while being pressed against the gentle slope portion 102d. As a result, a rotational force is applied to the cam 102, and the lid is automatically opened without applying a manual force (FIG. 8C).

Further, when the lid is further opened from this position, the trace portion 101 attempts to move along the next steep slope portion 102b, but returns to the concave portion 102a again and stops when the rotation load is no longer applied. . Since the lid opened at a predetermined angle in this manner can rotate in any direction according to the rotational load, there is no possibility that the hinge member is damaged,
In addition, there is an effect that the lid always stops at the position of the concave portion 102a unless a rotational load is applied, that is, the lid is held in an open state.

One set of cams is formed in a circumferentially point-symmetrical arrangement, and a concave portion, a steep slope portion, a convex portion, a gentle slope portion, and a concave portion are continuously formed. When the lid is closed, the trace portion is located on a steep slope lower than the convex portion. At this time, the tracing portion tends to descend on the steep slope portion due to the pressing force of the pressing means, so that the rotating force acts on the cam in the closing direction. Therefore, the lid rotates until it comes into contact with the main body, and further presses the lid toward the main body with a rotational load corresponding to the angle of the steep slope portion.

When the lid is manually rotated when the lid is opened, the cam rotates while pushing up the trace portion along the steep slope portion against the pressing force of the pressing means. When the trace part reaches the convex part and further rotates slightly, the trace part gets over the convex part and proceeds to the gentle slope part, and automatically descends to the concave part by the pressing force of the pressing means. As a result, a rotational force is applied to the cam, and the lid is automatically opened.

b is pushed up along the steep slope portion 8c and moved to the convex portion 8d of the automatic opening / closing branch point (B). When the plate member 10b is further rotated slightly, the plate member 10b goes over the convex portion 8d and proceeds to the gentle slope portion 8e. However, since the pressing force of the compression spring 8 acts, the plate member 10b automatically descends to the concave portion 8b. As a result, a rotational force is applied to the end face cam 8 and the lid 3 is automatically opened.

As described above, in the foldable portable telephone of the present invention, when the lid is closed, the trace portion is located on the slope of the cam convex portion. As the vehicle tries to descend on a steep slope, the cam is actuated in the closing direction. Therefore, the lid rotates until it comes into contact with the main body, and further presses the lid toward the main body with a rotational load corresponding to the angle of the steep slope portion.

As a result, no gap is formed between the lid and the main body when the lid is closed even if there is a manufacturing error during the assembly. Further, even when the cam is worn by the pressing force, this turning power is generated, so that there is no possibility that the lid vibrates with a slight turning power.
