In the foldable mobile phone, when a large pressing force acts on the surface of the lid (2) with the lid (2) closed as shown in FIG. 2, the cabinet of the lid (2) is made of resin. Since it easily deforms, there is a possibility that a load is directly applied to the sub-display disposed inside the sub-screen (22) and the liquid crystal display constituting the sub-display is cracked.
[0004]
Accordingly, an object of the present invention is to provide a portable electronic device in which a sub display is not likely to be damaged even when an external force is applied.
[0005]
[Means for solving the problems]
In the portable electronic device according to the present invention, the main display (31) and the sub display (32) are held in the frame (4) inside the flat cabinet, and are arranged in a back-to-back posture. (4) is provided with a rib (41) extending along the outer peripheral wall of the sub-display (32), and the rib (41) is provided with a flexible lead (33) pulled out from the sub-display (32). A missing portion is formed for passing through.
On the inner surface of the cabinet, a rod-shaped reinforcing member (5) extending over the missing portion of the rib (41) is attached. The frame (4) is formed with a plurality of seats (43) and (44) for receiving the reinforcing member (5). The flexible lead (33) extends between the opposing surfaces of the reinforcing member (5) and the frame (4).
The reinforcing member (5) can be formed using a material having a strength higher than that of the cabinet, for example, a metal such as stainless steel. The frame (4) can also be made of metal, for example.
[0006]
In the portable electronic device according to the present invention, the flexible lead (33) extending from the sub-display (32) passes through the missing portion of the rib (41) and is connected to an electronic circuit disposed outside the rib (41). The flexible lead (33) supplies a drive signal to the sub display (32).
Since the sub display (32) is surrounded by the rib (41) protruding from the frame (4), the rib (41) supplements the strength of the sub display (32). However, the effect of reinforcement by the rib (41) cannot be obtained for the missing portion of the rib (41). However, in the portable electronic device of the present invention, the reinforcing member (5) is disposed in the missing portion of the rib (41) and supported on the seats (43) and (44) of the frame (4). Even if a large external force is applied from the outer side to the missing portion of the rib (41), the external force is received by the reinforcing member (5). Therefore, the cabinet is not greatly deformed and the sub display (32) is not directly subjected to a load.
[0007]
In a specific configuration, the rib (41) of the frame (4) extends along the three outer peripheral walls of the four outer peripheral walls of the sub-display (32), and faces the outer peripheral wall of the remaining one side. The missing portion is formed, and the reinforcing member (5) extends from a position near one end of the outer peripheral wall of the one side to a position near the other end.
Thus, the sub-display (32) has three outer peripheral walls reinforced by the rib (41) of the frame (4) among the four outer peripheral walls, and the remaining one outer peripheral wall is a reinforcing member (5). ) Will be reinforced.
[0008]
More specifically, the frame (4) has a first area where the sub-display (32) is installed, and a second area following the first area. The flexible lead (33) is pulled out toward the second region, and the reinforcing member (5) is disposed to face the end of the second region on the first region side.
In the specific configuration, the boundary portion between the first region and the second region of the frame (4) corresponds to the central portion of the cabinet and is the portion that is most easily deformed by the action of external force. However, in the specific configuration, since the reinforcing member (5) is disposed in the vicinity of the central portion, the external force acting on the central portion is received by the reinforcing member (5). Therefore, there is no possibility that the sub display (32) is damaged by the action of external force.
[0009]
【The invention's effect】
In the portable electronic device according to the present invention, even if a large external force is applied to the cabinet, the external force is received by the reinforcing member, so that the sub display is not damaged.
