FIG. 10 is a perspective view showing a usage state of the playback device 150.
FIG. 11 is a perspective view showing a state in which the opening / closing lid 102 of the reproducing apparatus 150 is opened.

The reproducing apparatus 150 includes a substantially rectangular parallelepiped housing 101 having an outer peripheral wall portion 117f and an inner peripheral wall portion 117g and having a double housing structure, and a rotation shaft provided on the bottom surface side of the housing 101. An opening / closing lid 102 that rotates in the direction of the arrow DR101 around the CL 101 and opens / closes with respect to the housing 101, and a rotation shaft that rotates around a rotation axis set on the housing 101 side and closes the opening / closing lid 102 with respect to the housing 101. And three buckles 103 that are fixed in a state of being attached.
In addition, an electronic component, a speaker, and the like are accommodated in the inner casing 107 surrounded by the inner peripheral wall portion 117g.
The casing 101 and the opening / closing lid 102 are formed of a resin material.

The opening / closing lid 102 has a frame shape having an opening 102a at the center, and a packing sheet 104 made of silicon rubber is disposed on the housing 101 side of the opening 102a.
In the state where the opening / closing lid 102 is closed as shown in FIG. 10, the player DAP is pressed against the surface of the internal housing 107 by the packing sheet 104 and held.

The user can visually recognize the display screen of the player DAP through the packing sheet 104 and can operate the player DAP.

At this time, ribs 107b formed around the inner casing 107 and projecting from the mounting surface 107a bite into the packing sheet 104, preventing water from entering the space surrounded by the ribs 107b from the outside.
Therefore, if the opening / closing lid 102 is closed and fixed to the housing 101 by the buckle 103, the player DAP will not get wet even if the playback device 150 is exposed to shower water or rain.

Japanese Patent Laid-Open No. 7-319028

By the way, the reproducing apparatus 150 has a structure in which the buckle 103 is rotated to fix the opening / closing lid 102 to the casing 101, and water enters from the gap BM1 (see FIG. 10) between the buckle 103 and the casing 101. Therefore, the double casing structure described above and the packing sheet 104 are disposed, and the outer peripheral wall portion 117f allows water to enter the inside, while the inner casing 107 The intrusion of water into the interior is restricted.
Therefore, when showering or raining in the use state shown in FIG. 10, water that has particularly entered from the gap BM1 between the top buckle 103t and the housing 101 enters the outer peripheral wall 117f.

  FIG. 12 is a schematic cross-sectional view showing the relationship between the internal housing 107 and the packing sheet 104 corresponding to the S1-S1 cross section in which the open / close lid 102 is closed in FIG. The top surface side of the playback device 150 is shown in the upper part of FIG.

In FIG. 12, due to the action of the buckle 103 shown in FIG. 10, the packing sheet 104 is pressed against the inner housing 107 in the direction of the arrow DR21 to such an extent that the rib 107b of the inner housing 107 bites.
Similarly, the packing sheet 104 presses the player DAP placed on the placement surface 107a of the inner casing 107 against the placement surface 107a.

Here, the water that has entered the inside from the periphery of the buckle 103 reaches the top surface 107t of the inner casing 107 in the form of water droplets WT or splashes.
Most of the water reaching the top surface 107t flows downward through the outer wall of the inner casing 107 like the water droplet WT1 and is discharged to the outside, but a part of the water corresponds to the inner casing 107 (the inner peripheral wall portion 117g). ) And the protruding surface 104a that protrudes from the outer casing 107 on the surface of the packing sheet 104 that contacts the rib 107b.

  This is due to the effect of surface tension, and the amount of the accumulated water WT102 becomes more remarkable as the wettability of the resin forming the packing sheet 104 and the inner peripheral wall portion 117f is better.

  When the use is stopped in a state where the accumulated water WT102 is generated and the player DAP is taken out from the reproducing apparatus 150, the opening / closing lid 102 is opened with the casing 101 laid down as described above.

  FIG. 13 is a diagram showing a state in the middle of opening the opening / closing lid 102. When the opening / closing lid 102 is opened in the direction of the arrow DR22, the packing sheet 104 is also rotated and opened in the direction of DR22.

As can be seen from FIG. 13, the accumulated water WT102 held in contact with the two surfaces in the closed state of the open / close lid 102 is separated from the rib 107b by the opening operation, so that the one surface of the packing sheet 104 is removed. And cannot be held and falls as a droplet.
Since there is a player DAP below, there has been a problem that the player DAP gets wet by the dropped droplet, and improvement is required.

In addition, the inner casing 107 is covered with a packing sheet 104 so that water does not enter during use. However, it is not preferable that the surface 107a of the inner casing 107 is splashed with the opening / closing lid 102. .
That is, it is desirable that water does not drip from the packing sheet 104 when the opening / closing lid 102 is opened.

  Therefore, the problem to be solved by the present invention is to provide an electronic device having an opening / closing lid that does not drip from the opening / closing lid side even if the opening / closing lid is opened after use where water is applied.

In order to solve the above problems, the present invention has the following configurations 1) to 4) as means.

A connection cable (not shown) having a plug connected to the output terminal of the player DAP on the other end side is disposed between the intermediate plate 21 and the seat 22. The other end of the connection cable is connected to the speaker 5 through an electric circuit for adjusting the volume.
A recess (not shown) in which the connecting cable can be fitted into the intermediate plate 21
Is formed.

  When the player DAP is housed in the audio reproduction device 50 having the above-described configuration, first, the buckle 4 is opened to release the lock, and the front casing 1 is rotated around the rotation axis CL1 to be rear casing. Open to the body 2. Hereinafter, this state is referred to as an open state of the front housing 1.

Next, the connection cable is connected to the output terminal of the player DAP, the player DAP is positioned between the middle plate 21 and the sheet 22, and the front casing 1 is placed on the player DAP so that the sheet 22 is placed on the player DAP. Fit into the body 2 and rotate the buckle 4 in the closing direction to lock.
By this lock, the thin portion 22b of the sheet 22 is elastically deformed by the thickness of the player DAP, and the player DAP is urged against the surface 21a of the intermediate plate 21 by the repulsive force, and is sandwiched between the sheet 22 and the intermediate plate 21. The Hereinafter, this state is referred to as a closed state of the front housing 1.
FIG. 4 is a schematic cross-sectional view showing this closed state. FIG. 4 is a longitudinal sectional view of the playback device 50, with the right side of the drawing being the bottom side and the upper side being the front side.

In this closed state, the user can visually recognize the screen of the player DAP from the outside through the thin portion 22b of the sheet 22, and can operate an input such as a push button disposed on the surface via the thin portion 22b. .
Therefore, the audio content stored in the player DAP can be reproduced from the speaker 5 by an external operation via the seat 22 on the player DAP.

FIG. 5 is an enlarged view of part A in FIG. 4 and shows a posture in which the top side in use is in an upward direction.
Further, the inner peripheral wall 2g is illustrated as a partial cross section.

In FIG. 5, the seat 22 is pressed against the inner peripheral wall portion 2g in the direction of the arrow DR2 so that the protruding rib 2g1 of the inner peripheral wall portion 2g bites in by the action of the buckle 4 shown in FIG. Yes.
Similarly, the thin portion 22b of the sheet 22 presses the player DAP against the middle plate 21 in the direction of the arrow DR3.
Further, the rib 22c of the sheet 22 is formed such that the inner wall surface 22c3 thereof is positioned with no gap or a slight gap with respect to the top surface 2gt of the inner peripheral wall portion 2g.

Here, the water that has entered from the periphery of the buckle 4 through the clearance of the outer peripheral wall 2f (not shown in FIG. 5) reaches the top surface 2gt of the inner peripheral wall 2g in the form of water droplets WT or splashes. .
The top surface 2gt of the inner peripheral wall portion 2g is slightly inclined toward the bottom surface from the front to the rear (from the right to the left in FIG. 5). Further, it is formed so as to be slightly inclined toward the bottom surface side from the center toward both side surfaces, that is, from the center toward the front side and back side in FIG.
Therefore, most of the water that has reached the top surface 2gt flows backward and downward through the outer wall of the outer peripheral wall portion 2f like the water droplet WT1 shown in FIG.

  On the other hand, water droplets or the like that have reached the vicinity of the rib 22c of the sheet 22 come into contact with the two surfaces of the outer wall surface 22c1 of the rib 22c and the inner surface 22c2 outside the rib 22c of the sheet 22 and accumulate as water WT2.

This is due to the effect of surface tension, and the amount of retained water WT2 that is retained becomes more pronounced the better the wettability of the resin that forms the sheet 22 and the inner peripheral wall 2g.
Further, the larger the area of the outer wall surface 22c1 and the inner surface 22c2 in the range corresponding thereto, the larger the amount of the wall surface is retained.
Further, there is a slight amount of water held between the front end surface 22cst of the rib 22c and the top surface 2gt of the inner peripheral wall portion 2g, but since the width W1 of the rib 22c is formed as small as about 0.5 mm, it is held. The amount is negligibly small.

FIG. 6 is a perspective view schematically showing a state in which the accumulated water WT2 is held.
This FIG. 6 is shown with the left and right directions reversed with respect to FIG.

  Water such as a shower or rain enters the inside through the gap between the buckle 4 and the outer peripheral wall 2f from the outside, for example, along the route of the arrow SK, and part of the water reaches the vicinity of the seat 22.

  When the use of the regenerator 50 is stopped in the state where the accumulated water WT2 is generated, and the player DAP is taken out from the regenerator 50, the front case 1 is opened with the case 3 laid down.

  FIG. 7 is a cross-sectional view showing the sheet 22 and the like in a state where the front housing 1 is being opened. The seat 22 rotates in the arrow DR4 direction together with the front housing 1.

As can be seen from FIG. 7, even when the front housing 1 is opened, the accumulated water WT2 is in contact with the two surfaces of the outer wall surface 22c1 of the rib 22c and the inner surface 22c2 outside the rib 22c of the seat 22, It is maintained while being held on the two surfaces. That is, the accumulated water WT2 remains attached to the front housing 1 side.
Therefore, the accumulated water WT2 does not fall downward and the player DAP does not get wet. Further, since water does not drip around the intermediate plate 21 and its surroundings, water does not enter the storage chamber 2r.

Next, the length L1 of the rib 22c will be described with reference to FIG.
FIG. 8 is a perspective view as seen from the upper rear side of the playback device 50 and shows a state in which the buckle 4 is removed. In this state, the rotation shaft portions 4j and 4j that engage with the buckle 4 are visually recognized.
Further, the pooled water WT2 held by the outer wall surface 22c1 and the inner surface 22c2 of the rib 22c is indicated by a dotted region where the outline is a one-dot chain line.

In FIG. 8, three ribs 23L, 23R, and 23C at the center on the left and right sides that secure the rigidity of the rear housing 2 by connecting the inner peripheral wall portion 2g and the outer peripheral wall portion 2f are formed.
Among these ribs, at least the left and right ribs 23L and 23R form a gap between the inner surface 22c2 of the seat 22 and the ribs 22c in the closed state. This gap becomes a water discharge path.

Specifically, as described above, since the top surface 2gt is inclined on both sides of the rib 23C, most of the water that reaches the top surface 2gt from the gap between the buckle 4 and the outer peripheral wall portion 2f It discharges | emits by the path | route of the arrows SK1 and SK2 of FIG.
Accordingly, the length L1 of the rib 22c is set to such a length as to form a discharge path for water that reaches the top surface 2gt on the outside of both ends thereof.

  As described above, the regeneration device 50 according to the embodiment allows the accumulated water WT2 to come into contact with the two surfaces of the sheet 22, so that water does not drip when opening the front casing 2 that is an open / close lid. This is an effect.

  The embodiment of the present invention is not limited to the configuration and procedure described above, and it goes without saying that modifications may be made without departing from the scope of the present invention.

  The shape of the sheet 22 in the vicinity of the rib 22c can be modified as shown in FIG. Each drawing in FIG. 9 is a cross-sectional view of the vicinity of the rib 22 c of the sheet 22.

FIG. 9A shows an example in which a reservoir 22d extending inward is formed at a portion where the outer wall surface 22c1 and the inner surface 22c2 of the rib 22c intersect.
Since a larger amount of water can be retained as the accumulated water WT2 by the reservoir 22d, dripping of water when the front housing 1 is opened is extremely well prevented.

FIG. 9B is an example in which R is provided on the 22c2 side of the tip surface 22cst of the rib 22c.
By this rounding, the amount of water held slightly by the tip 22st of the rib 22c and the top surface 2gt of the inner peripheral wall portion 2g can be further reduced, so that dripping of water when the front housing 1 is opened. Is very well prevented.

FIG. 9C shows an example in which the surfaces of the outer wall surface 22c1 and the inner surface 22c2 of the rib 22c are roughened.
Due to this roughening, the accumulated water WT2 held in contact with both surfaces adheres firmly, so even if an impact or the like is applied when the front housing 1 is opened, the accumulated water WT2 may droop downward. Extremely less.

  The examples and the modified examples can be arbitrarily combined with each other.
