FIG. 3 is an explanatory view showing a cross-section of the central portion of the intercom handset 1 in the left-right direction when the interphone handset 1 is placed on the floor surface with the front side facing downward.

  The intercom handset 1 has a main body case including a front case 2 disposed on the front side, a rear case 3 disposed on the rear side, and a decorative panel 4 attached so as to cover the front surface of the front case 2. doing. A camera window 5 is opened at the upper front of the main body case (opened in both the front case 2 and the decorative panel 4), and the camera lens 6 exposed in the camera window 5 is a lens. A camera unit covered with a cover 7 is provided. The lens cover 7 bulges forward from the front surface of the main body case through the camera window 5, and has a bulging portion 7a whose front surface is a curved surface curved in the left-right direction, and a peripheral edge of the bulging portion 7a. And a flange portion 7b for preventing the camera window 5 from coming off.

  On the other hand, on the right side of the camera unit on the front side of the main body case, a microphone unit 8 for calling is provided. A speaker unit 9 for calling is provided below the camera unit, and a call button 10 that is operated when a visitor calls a resident is provided below the speaker unit 9. It has been. Such interphone slave unit 1 is installed on the wall surface of the entrance of the dwelling unit, etc., and in response to the operation of the call button 10 by the visitor, the interphone master unit (not shown) installed in the dwelling unit And activate the camera to capture the visitors. In addition, the video imaged by the camera is displayed on a monitor provided in the intercom master unit. Reference numeral 20 denotes a base for attaching the interphone slave unit 1 to a wall surface or the like.

Here, a protection structure for protecting the lens cover 7 which is a main part of the present invention will be described.
The speaker unit 9 provided on the lower side of the camera unit includes a speaker 11 built in the main body case and a speaker panel 12 provided on the front surface of the main body case so as to cover the front of the speaker 11. The speaker panel 12 is a plate-like member made of synthetic resin having a rectangular shape in front view in which a speaker hole 13 that is long in the vertical direction is opened substantially in the center, and its upper side is adjacent to the lower side of the lens cover 7. It is assembled as a part of the decorative panel 4. A protective protrusion 14 extending in the left-right direction along the upper side is projected forward from the upper end of the front surface of the speaker panel 12 (which is a substantially central portion in the vertical direction in the front of the main body case). ing. The protective protrusion 14 is formed integrally with the speaker panel 12 and is formed so that the amount of protrusion gradually increases from the left and right ends toward the center. That is, the front end of the protective protrusion 14 has a curved shape with the center portion bulging most forward. Further, the maximum protruding portion (the central portion in the left-right direction) of the protective protrusion 14 protrudes to the front most on the front surface of the main body case (particularly to the front from the surface of the bulging portion 7a of the lens cover 7).

  According to the intercom handset 1 having the above-described configuration, the speaker panel 12 is attached to the lower side of the lens cover 7 provided on the front surface of the main body case so as to be adjacent to the lens cover 7, and at least a part of the speaker panel 12 is attached. A protective protrusion 14 protruding forward from the surface of the lens cover 7 extends in the left-right direction along the upper side of the speaker panel 12 (the edge of the speaker panel 12 adjacent to the lens cover 7). Yes. In other words, at a position adjacent to the lower side of the lens cover 7, the protective protrusion 14, at least a part of which protrudes forward from the surface of the lens cover 7, extends in the left-right direction along the lower side (lower edge) of the lens cover 7. It is extended. Therefore, when the intercom handset 1 is placed on the floor surface or the like with its front surface facing down, the protective protrusion 14 is more reliably in contact with the floor surface than the lens cover 7. In the general interphone handset 1, the center of gravity is often located at the upper part of the main body case due to the weight of the camera. The corners and the protective protrusions 14 are supported in a state where they are in contact with the floor surface. Therefore, the contact part with the floor surface of the lens cover 7 can be limited to the upper corner, and the situation where the lens cover 7 is damaged can be suppressed. Furthermore, even if it is damaged, it is the upper corner of the lens cover 7, so that the scratch does not appear in the image (that is, it does not hinder the image).

Further, since the protective protrusion 14 is integrally formed with the speaker panel 12, the protective protrusion 14 can be provided along the lower side of the lens cover 7 simply by attaching the speaker panel 12. It is possible to simplify the work for installation and to reduce the number of parts.
Furthermore, since the protective protrusion 14 is provided along the upper side of the speaker panel 12, the protective protrusion 14 is located at the boundary between the camera unit and the speaker unit 9. In addition, the boundary is substantially centered in the vertical direction on the front surface of the main body case, and further, the protective protrusion 14 is formed so as to gradually increase from the left and right ends toward the center. The tip of the protective protrusion 14 is formed in a curved shape resembling the surface of the bulging portion 7 a of the lens cover 7. Therefore, the protection protrusion 14 is not conspicuous, and the external appearance of the intercom handset 1 is not impaired.

  Note that the interphone device according to the present invention is not limited to the aspect of the above-described embodiment, and the overall configuration of the interphone device as well as the configuration related to the protective protrusions and the like depart from the spirit of the present invention. As long as it is not necessary, it can be changed as needed.

  For example, in the above embodiment, the protective ridge is provided along the lower edge of the lens cover. However, the protective ridge may be provided along the upper edge of the lens cover, and the position of the protective ridge is appropriately designed. It can be changed. And in the said embodiment, when it puts on the floor surface etc. with the front surface of a main body case facing down, it is comprised so that a main body case may be supported by a protection protrusion and the upper corner part of a lens cover, By providing a protective protrusion along the upper edge of the cover, the main body case may be supported by the protective protrusion and the calling button. With such a configuration, it is possible to further protect the lens cover. In the above embodiment, since the center of gravity of the interphone device is positioned on the camera side, the main body case is supported by the protective protrusion and the upper corner of the lens cover. However, the center of gravity of the interphone device is positioned on the speaker side. Thus, even if the protective protrusion is provided along the lower edge of the lens cover, the main body case can be supported by the protective protrusion and the calling button.

Further, protective ridges may be provided on the upper edge and the lower edge of the lens cover (that is, two protective ridges may be provided), and the number of protective ridges can be appropriately changed.
Furthermore, there is no problem even if a rib-shaped protective ridge is provided in which the tip of the protective ridge is not curved and the amount of forward protrusion is constant. In addition, the protective protrusion may be a separate member from the speaker panel, or may be integrally formed with the decorative panel body, for example. In addition, the shape of the protective protrusion may be formed to be curved upward or downward in the left-right direction depending on the shape of the lens cover, and at least a part may protrude forward from the lens cover. The design can be changed as appropriate.

Furthermore, the positional relationship between the lens cover and the speaker unit can be changed as appropriate. For example, in the case where the speaker unit is provided on either the left or right side of the lens cover, a protective projection is provided along the side edge of the lens cover. There is no problem even if a line is formed.
In addition, in the above embodiment, an interphone slave device that is an example of an interphone device has been described. However, other interphone devices such as a collective entrance device may be used as long as the lens of the camera is covered with a lens cover. There is no problem.
