In the example shown in FIG. 2B , the mounting table 6 has an inclined surface 61 whose inclination angle is set to α1 with respect to a horizontal plane (a plane orthogonal to the vertical direction), and the casing 18 is attached to the inclined surface 61 . For example, as shown in FIG. 2B , in the case where the optical axis P1 of the lens 152 is parallel to the normal direction of the front surface 181 of the housing 18 , the imaging range of the imaging unit 15 is set upward, and the visitor in the front may be Not included in the imaging range of the imaging unit 15 . Therefore, at this time, it is preferable to adjust the angle of the optical axis P1 of the lens 152 so that the optical axis P1 of the lens 152 faces downward with respect to the normal direction of the front surface 181 of the housing 18 . The walkie-talkie device 1 of the present embodiment is provided with an angle adjustment structure 19 so that the angle of the optical axis P1 of the lens 152 can be adjusted. Hereinafter, the angle adjustment structure 19 will be described with reference to FIGS. 3A to 3D . In addition, the "optical axis of the lens" referred to here is the center of the viewing angle (viewing angle), and is the center of the range of the imaging element reflected in the image drawn by the lens.

The angle adjustment structure 19 includes a first fixing member 191 and a second fixing member 192 as shown in FIGS. 3A to 3D .

As shown in FIGS. 3A and 3B , the first fixing member 191 is formed in a trapezoidal shape by a front surface portion 1911 , an upper surface portion 1912 , a lower surface portion 1913 , a left surface portion 1914 , and a right surface portion 1915 as viewed from the left-right direction as shown in FIGS. 3A and 3B .

In addition, the left surface portion 1923 is inclined more obliquely to the right as it goes forward, and the right surface portion 1924 is inclined more obliquely to the left as it goes forward. A circular window hole 1925 for exposing the lens 152 of the imaging unit 15 to the front is provided in the center of the lower surface portion 1922 .

Here, in the walkie-talkie device 1 according to the present embodiment, any one of the first fixing member 191 and the second fixing member 192 is selected according to the installation site to which the walkie-talkie device 1 is attached, and the imaging unit 15 is fixed to the camera unit 15 via the selected fixing member. Mounted on the housing 18 .

For example, as shown in FIG. 4A , when the walkie-talkie device 1 is attached to the wall surface 200 extending in the vertical direction (up-down direction), the imaging unit 15 is preferably attached to the casing 18 via the first fixing member 191 . At this time, the optical axis P1 (= P11 ) of the lens 152 is in a direction parallel to the normal direction of the front surface 181 of the housing 18 , so that visitors who are located in front of the walkie-talkie device 1 can be included in the imaging range of the imaging unit 15 .

Furthermore, as shown in FIG. 4B , when the walkie-talkie device 1 is mounted on the inclined surface 61 of the mounting table 6 , the imaging unit 15 is preferably mounted on the casing 18 via the second fixing member 192 . At this time, the imaging unit 15 is attached to the lower surface portion 1922 of the second fixing member 192, and the optical axis P1 (=P12) of the lens 152 is adjusted downward as compared with the case where the first fixing member 191 is used. As a result, a visitor or the like located in front of the walkie-talkie device 1 can be included in the imaging range of the imaging unit 15 . In other words, when the imaging unit 15 is attached to the casing 18 via the second fixing member 192 , the optical axis P1 of the lens 152 is inclined with respect to the normal direction (downward) of the front surface 181 of the casing 18 .

In the walkie-talkie device 1 of the present embodiment, the angle adjustment structure 19 includes a plurality of types of fixing members (a first fixing member 191 and a second fixing member 192 ) whose adjustment angles of the optical axis P1 of the lens 152 are different from each other. Furthermore, the imaging unit 15 is attached to the casing 18 via any one of a plurality of fixing members in accordance with the adjustment angle of the optical axis P1 of the lens 152 . According to this configuration, the angle of the optical axis P1 of the lens 152 can be adjusted in stages according to the fixing member selected from the plurality of fixing members (the first fixing member 191 and the second fixing member 192 ).

In addition, in a state where the imaging unit 15 is attached to the casing 18 by either the first fixing member 191 or the second fixing member 192, as shown in FIGS. 3B and 3D, the lens 152 is larger than the front 181 of the casing 18. more protruding forward. According to this configuration, there is an advantage that a part of the casing 18 and the like is not easily reflected in the imaging range of the imaging element 151 .

(4) Adjustment method of the imaging range of the imaging section Next, the adjustment method of the imaging range of the imaging section 15 will be described.

First, the builder selects one of the first fixing member 191 and the second fixing member 192 according to the installation site of the walkie-talkie device 1 , and attaches the imaging unit 15 to the casing 18 via the selected fixing member. The builder selects the first fixing member 191 when attaching the intercom device 1 to the wall surface 200 , and selects the second fixing member 192 when attaching the intercom device 1 to the inclined surface 61 of the mounting base 6 . When the imaging unit 15 is attached to the casing 18 via the first fixing member 191 , as shown in FIG. 4A , the optical axis P1 of the lens 152 is a direction parallel to the normal direction of the front surface 181 of the casing 18 . When the imaging unit 15 is attached to the housing 18 via the second fixing member 192 , the optical axis P1 of the lens 152 is inclined downward with respect to the normal direction of the front surface 181 of the housing 18 as shown in FIG. As a result, the optical axis P1 of the lens 152 of the imaging unit 15 is adjusted.

Next, by performing a specific operation on the first operation unit 16 , the builder displays the image captured by the imaging unit 15 on the first display unit 14 . Then, the construction worker adjusts the imaging range of the imaging unit 15 while viewing the image displayed on the first display unit 14 . For example, when adjusting the imaging range of the imaging unit 15 upward, the construction worker presses the “1” button included in the first operation unit 16 . When an operation signal from the first operation unit 16 is input, the angle adjustment unit 131 of the first image processing unit 13 cuts out a portion above the image displayed on the first display unit 14, and displays the cut out image on the first display unit 14. 1 Display section 14. As a result, the optical axis P1 of the lens 152 is adjusted to be imaginary upward, and as a result, the imaging range of the imaging unit 15 is adjusted upward. Moreover, when adjusting the imaging range of the imaging part 15 downward, the construction worker presses the "2" button included in the first operation part 16 . When an operation signal from the first operation unit 16 is input, the angle adjustment unit 131 cuts out a portion below the image displayed on the first display unit 14 and displays the cutout image on the first display unit 14 . Thereby, the optical axis P1 of the lens 152 is adjusted imaginatively downward, and as a result, the imaging range of the imaging unit 15 is adjusted downward. That is, the angle adjustment unit 131 receives an operation input from the user (constructor) in a state where the image from the imaging unit 15 attached to the casing 18 via the angle adjustment structure 19 is displayed on the first display unit 14 . The signal of the first operation unit 16 adjusts the cut-out position of the image.

Here, FIG. 5 is a schematic diagram showing the adjustment range of the optical axis P1 of the lens 152 . P11 in FIG. 5 is the optical axis of the lens 152 when the imaging unit 15 is attached to the casing 18 via the first fixing member 191 . In addition, P12 in FIG. 5 is the optical axis of the lens 152 when the imaging unit 15 is attached to the casing 18 via the second fixing member 192 . That is, depending on which of the first fixing member 191 and the second fixing member 192 is used, the angle of the optical axis P1 of the lens 152 can be adjusted within the range of θ2. On the other hand, the angle adjustment unit 131 virtually adjusts the optical axis P1 according to the cut-out position of the image captured by the imaging unit 15 .
