[0014] Intercom handset 1 has a main body case 2, which is made up of a front case 2A and a rear case 2B, and a mounting base 3 attached to the rear of main body case 2 for mounting main body case 2 on a wall. A camera unit 4 for capturing images of the surroundings and visitors, and a microphone unit 5 for making calls, are provided at the upper front surface of main body case 2. A speaker unit 6 for making calls is provided below camera unit 4 on the front surface of main body case 2, and a call button 7 that a visitor presses to call a resident is provided below speaker unit 6. Intercom handset 1 is installed by fastening mounting base 3 to a wall, such as the entrance of a residence. When a visitor presses call button 7, it calls an intercom master unit (not shown) installed in the residence and activates camera unit 4 to capture an image of the visitor.
[0015] Here, the waterproof structure of the terminal 10, which is the main part of the present invention, will be described in detail. First, the structure of the main body case 2 will be described. A storage recess 11 is provided on the rear surface of the main body case 2, recessed forward. A terminal 10 (shown in FIG. 4) is provided in the storage recess 11 to which a cable (a cable extending from the wall, not shown) drawn from within the wall is connected. A drainage notch 12 is provided in the lower right corner of the storage recess 11, and the rear edge of the underside of the storage recess 11 forms an inclined surface 11A that slopes downward to the right toward the notch 12 when viewed from the front. This allows water droplets that have entered the storage recess 11 to be guided downward to the right and drained out of the storage recess 11 via the notch 12. A rubber waterproof board 13 is attached to the rear surface of the main body case 2, adjacent to the upper side of the storage recess 11. Reference numeral 14 denotes an attachment recess for attaching the waterproof board 13.
[0016] Next, the structure of the mounting base 3 will be described. On the front surface of the mounting base 3, side walls 21, 21 extending in the vertical direction along the left and right edges of the mounting base 3, and an upper wall 22 connecting the upper ends of the side walls 21, 21 on the left and right, protrude forward. When the main body case 2 is attached to the front surface of the mounting base 3, the mounting base 3 covers the rear of the terminal 10, the side walls 21, 21 are located on the left and right outer sides of the storage recess 11, respectively, and the upper wall 22 abuts against the waterproof plate 13 above the storage recess 11 (FIG. 7). The upper wall 22 is shaped so that its center in the left-right direction is located at the top and slopes downward to both the left and right sides. In addition, a cable port 23 for pulling the cable into the main case 2 is provided in the area between the left and right side wall portions 21, 21, at a position that is behind the inclined surface 11A when the main case 2 is assembled, and when viewed from the rear as shown in Figure 2, the inclined surface 11A is exposed within the cable port 23.
[0017] According to the intercom handset 1 having the above-described configuration, a storage recess 11 recessed forward is provided on the rear surface of the main body case 2, terminal 10 is placed in this storage recess 11, and when the main body case 2 is attached to the mounting base 3, the rear of terminal 10 is covered by the mounting base 3. Therefore, since terminal 10 is covered from above and on the left and right sides by the main body case 2 and from the rear by the mounting base 3, it is possible to provide a level of waterproofing that meets the requirements without attaching a cover member as in the past, and intercom handset 1 can be made smaller and thinner.
[0018] In addition, a rubber waterproof plate 13 is attached to the upper side of the storage recess 11 on the rear surface of the main body case 2, while the mounting base 3 is provided with an upper wall portion 22 that protrudes forward and whose tip abuts against the waterproof plate 13, so that waterproofness can be improved without providing a cover member. Furthermore, the underside of the storage recess 11 is an inclined surface 11A that slopes downward to the right, while the mounting base 3 is provided with a cable port 23 for pulling the cable into the main body case 2, and the inclined surface 11A is exposed within the cable port 23. Therefore, even if water droplets enter the main body case 2 through the cable port 23, the entered water droplets can be smoothly guided to the lower side of the main body case 2, resulting in an intercom handset 1 with even higher waterproofing.
[0019] In addition, the intercom device of the present invention can be modified as needed, as long as the overall configuration of the intercom device, as well as the configuration related to the waterproof structure of the terminals, etc., does not deviate from the spirit of the present invention.
[0020] For example, in the above embodiment, a storage recess is provided in the main body case and the terminal is placed within the storage recess, but instead of providing a storage recess in the main body case, a rib that protrudes forward may be provided on the mounting base so that the top of the terminal is covered by the rib. Furthermore, the waterproof plate and upper wall portion may not be provided, and the shape of the lower surface of the storage recess and the position of the cable port on the mounting base may also be modified as appropriate. Additionally, although the above embodiment has been described with reference to an intercom slave unit, which is an example of an intercom device, the present invention can also be suitably applied to other intercom devices such as an intercom master unit.
