A holder (4) holding a pair of left and right speakers (5) and (5) for generating a ringing tone or the like is attached to the rear surface of the main chassis (14). The holder (4) has two sound introduction holes (41) and (41) for guiding the sound emitted from both speakers (5) and (5) to the main chassis (14) side.

  The main chassis (14) has three through holes (11), (11), and (11) at positions facing the three operation keys (71), (71), and (71). Two sound guide holes (12) and (12) interposed between the holes (11), (11) and (11) are opened, and the sound guide holes (12) and (12) are used to guide the sound of the holder (4). The sound that has passed through the holes (41) and (41) is further guided to the front cover panel (2) side.

Each sound guide hole (12) is blocked by a breathable waterproof sheet (6), thereby preventing water from entering the main body from the sound guide hole (12).
In addition, a waterproof packing member (9) is attached to each of the three through holes (11), (11), and (11) of the main body chassis (14), thereby allowing water to enter the main body from the through holes (11). Is blocked.

As shown in FIG. 6, the waterproof packing member (9) has a bottomed bag-shaped packing body (91) formed by protruding a bottomed cylindrical portion (93) at the center of a flange portion (92) having a center hole. A cylindrical stainless steel metal piece (94) is provided on the inner peripheral surface of the packing body (91), thereby suppressing the elastic deformation of the waterproof packing member (9) in the lateral direction. ing.
Here, the packing body (91) is formed of transparent silicon rubber.
The waterproof packing member (9) is attached to the main body chassis (14) by inserting a bag-like portion into the through hole (11) of the main body chassis (14) as shown in FIG.

  As shown in FIG. 5, the front cover panel (2) has three openings (22), (22) and (22) formed in a substantially line along the two sound emitting holes (23) and (23). As shown in FIG. 3, the heads of the operation keys (71), (71), and (71) protrude from the openings (22), (22), and (22), respectively.

As shown in FIG. 4, the operation key (71) includes a key body (72) having a pusher (75) protruding therefrom, and extends over the three operation keys (71) (71) (71). A key sheet (73) covering the head surface of the main body (72) is provided, and a symbol for displaying the function of the operation key (71) is provided on the surface of the key sheet (73) for each operation key (71). A hollow print layer (74) is formed.
Three operation keys 71, 71 and 71 are connected to each other by the key sheet 73, and an integrated operation key unit 7 is constructed as shown in FIG.
The pusher (75) of each operation key (71) is inserted into each waterproof packing member (9).

  Here, the key body (72) of each operation key (71) is made of transparent polycarbonate, and the key sheet (73) is made of elastomer.

  In the operation key unit (7), when one operation key (71) is pressed, the pusher (75) of the operation key (71) is connected to one tact switch (9) via the bottom of the waterproof packing member (9). 81) is pressed to turn on the tact switch (81). As a result, an operation signal corresponding to the tact switch (81) is generated.

Further, as shown in FIG. 4, a light emitting element (80) made of LED is mounted on the surface of the flexible substrate (8) at a position near the tact switch (81).
Light emitted from the light emitting element (80) is incident on the packing body (91) of the waterproof packing member (9), passes through the packing body (91), and then enters the key body (72) of the operation key (71). Incident. The light travels through the key body (72), passes through the key sheet (73), and is emitted from the cutout portion of the printing layer (74).
In this way, the surface of the operation key (71) is illuminated, and the operation key (71) can be easily operated particularly at night.

Here, since the metal piece (94) is provided on the inner peripheral surface of the packing body (91) of the waterproof packing member (9), the light transmitted through the packing body (91) is transmitted to the waterproof packing member (9). Even if the light travels toward the inner peripheral surface, the light is reflected by the inner peripheral surface of the metal piece (94) and enters the key body (72) of the operation key (71).
Therefore, the light emitted from the light emitting element (80) is guided to the surface of the operation key (71) with almost no leakage to the outside.

Further, the main body chassis (14) has a light emitting element (80), a packing body (91) of the waterproof packing member (9), or a key body (72) of the operation key (71) on the side of the operation key (71). Ribs (13) protruding from the surface of the main chassis (14) toward the inner surface of the front cover panel (2) in order to block light traveling toward the sound emission holes (23) of the cover panel (2). ) Is formed.
Therefore, light does not leak to the outside from the sound emission hole (23) of the cover panel (2).

  In the mobile phone described above, the two guides interposed between the three through holes (11), (11), and (11) through which the pusher (75) of the operation key (71) should pass through the main body chassis (14). Although the sound holes (12) and (12) are established, each of the through holes (11) is individually sealed by the waterproof packing member (9), so that the three waterproof packing members (9) and (9) ( 9) can be arranged regardless of the presence of the sound guide holes (12) and (12).

In addition, since the packing body (91) of the waterproof packing member (9) and the key body (72) of the operation key (71) exhibit a light guide action for illuminating the surface of the operation key (71). Both the waterproof packing member (9) seals the through hole (11) of the main chassis (14) and the light guide structure that guides the light from the light emitting element (80) to the surface of the operation key (71). Will be configured.
Therefore, the waterproof structure and the light guide structure are arranged in a compact manner, and the mobile phone can be downsized.

In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim.
For example, it is possible to perform printing for preventing light leakage on a necessary portion of the surface of the waterproof packing member (9).
