DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing structure containing an electronic device, and more particularly to a waterproof structure for preventing liquid from entering the inside of the housing.

[0002]

2. Description of the Related Art Conventionally, a housing of an electronic device installed in a room such as an office has a joint between a cover and a main body on an upper surface thereof. Some of such housings are provided with a key for fixing the cover to the main body.

[0003]

In the above-described housing structure, the joint between the cover and the main body is on the upper surface of the housing.
When a liquid such as water spills on the upper surface of the housing, the liquid enters the housing. As a result, there is a problem that the liquid that has entered inside adheres to the electronic device, and the electronic device breaks down. In a case structure provided with a key for fixing the cover to the main body, the liquid enters the inside of the case from the key portion. In such a case, use of a waterproof member such as a waterproof cover or waterproof packing can be considered to prevent the liquid from entering the inside of the housing. However, if the type of the key is different, the type of the waterproofing member must be changed. Therefore, a dedicated waterproofing member must be used for each of the housings having different key types. Therefore, there is a problem that the cost increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an electronic apparatus capable of preventing liquid from entering the inside of a housing without using a waterproof member such as a waterproof cover or a waterproof packing. It is intended to provide a waterproof structure.

[0005]

According to a first aspect of the present invention, there is provided a waterproof structure for an electronic device, wherein a housing comprises a main body for supporting the electronic device and a cover for covering the main body. The main body is covered so that the joint with the main body is not exposed on the upper surface of the housing. In this way, the cover covers the main body so that the seam between the main body and the housing is not exposed on the upper surface of the housing, so that the seam between the main body and the cover does not exist on the upper surface of the housing, thereby preventing intrusion of liquid from the upper surface of the housing. can do. Further, as described in claim 2, the casing has a member for receiving a liquid entering from a cover fixing key provided on an upper surface of the casing.

[0006]

Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a housing showing a waterproof structure of an electronic device according to an embodiment of the present invention. As shown in FIG. 1A, a housing 1 that houses an electronic device such as a printer or a copier includes a main body 2 that supports an electronic device (not shown) and a cover 3 that covers the main body 2. .

The main body 2 includes a bottom member 2 serving as a bottom surface of the housing 1.
a and a side member 2b which is one side of the housing 1 integrally with the bottom member 2a. The cover 3 includes an upper surface member 3a serving as an upper surface of the housing 1 and a side member 3b serving as three side surfaces of the housing 1 integrally with the upper surface member 3a.
The horizontal sizes W and L of the bottom member 2a of the main body 2 and the top member 3a of the cover 3 are the same as the horizontal size of the housing 1 when the main body 2 and the cover 3 are integrated.

The height H2 of the side member 2b of the main body 2
Is shorter by the height of the upper surface member 3a of the cover 3 than the height H1 of the housing 1 when the main body 2 and the cover 3 are integrated (accurately, the fitting of the main body 2 and the cover 3). It is slightly shorter in order to allow room in the case). Similarly,
The height H3 of the side member 3b of the cover 3 is equal to the height H of the housing 1.
It is shorter than 1 by the height of the bottom member 2a of the main body 2 (accurately, it is slightly shorter in order to allow a margin for fitting the main body 2 and the cover 3).

With the above structure, when the main body 2 and the cover 3 are integrated as shown in FIG. 1B, the joint between the main body 2 and the cover 3 appears on the side surface of the housing 1, and 1 is not present on the upper surface. Thereby, intrusion of the liquid from the upper surface of the housing 1 can be prevented, and failure of the electronic device due to intrusion of the liquid can be prevented.

FIG. 2 is a view showing a structure of a key portion for fixing the cover 3 to the main body 2. In FIG. 2, reference numeral 4 denotes an electronic device. The cover 3 is fixed to the main body 2 (not shown in FIG. 2) by the key portion 5 arranged on the upper surface member 3a of the cover 3.

Here, a member 6 for receiving a liquid entering from the key portion 5 is provided directly below the key portion 5. Accordingly, even if a liquid such as water spilled on the upper surface (upper surface member 3 a) of the housing 1 passes through the key portion 5 and enters the housing 1, the liquid is received by the member 6. It does not adhere to the electronic device 4. Thus, the influence on the electronic device 4 can be prevented.

With the above structure, a waterproof member such as a waterproof cover or a waterproof packing is not required. Since the member 6 can be used for general purposes regardless of the type of the key portion 5, a common member 6 can be used for housings having different types of key portions, and the cost of the housing 1 can be reduced. can do. It is needless to say that the member 6 may be attached to either the main body 2 side or the cover 3 side as long as the member 6 is disposed immediately below the key portion 5.

[0013]

According to the present invention, as described in claim 1, the joint with the main body is prevented from being exposed on the upper surface of the housing.
Since the cover covers the main body, a seam between the main body and the cover does not exist on the upper surface of the housing, so that intrusion of liquid from the upper surface of the housing can be prevented, and failure of the electronic device due to intrusion of the liquid can be prevented. it can.

According to a second aspect of the present invention, a member for receiving a liquid entering from a key portion for fixing the cover is provided inside the housing to prevent the liquid from adhering to the electronic device. Thus, failure of the electronic device can be prevented. Further, since a waterproof member such as a waterproof cover or a waterproof packing is not required, there is no need to limit the type of key, and the cost of the housing can be reduced.
