The camera 10 includes a lens holder 11 that holds the lens 5 exposed on the front end surface, and a circuit board 12 that mounts an imaging device (not shown) and is fixed to the rear side of the lens holder 11. It is installed in the body case by the camera holder 13 . The camera holder 13 includes a camera holding portion 15 capable of holding the camera 10 while the cylindrical portion of the lens holder 11 is inserted therethrough, and a camera holder 13 that protrudes left and right from the camera holding portion 15 and is elastically deformable so as to bend in the front-rear direction. It has screwing pieces 16 , 16 . The rear surface of the camera holding portion 15 is provided with a concave portion 17 which is concave forward and which can accommodate the base portion 11A of the lens holder 11 . A circular hole 18 is formed in the concave portion 17 so as to penetrate in the front-rear direction. In the camera holder 13, the base portion 11A of the lens holder 11 is accommodated in the concave portion 17, the base end side of the cylindrical portion of the lens holder 11 is positioned in the circular hole 18, and the distal end side of the cylindrical portion of the lens holder 11 is positioned. The camera 10 can be held while protruding forward from the camera holding portion 15 . A retainer portion 11B having a larger diameter than the circular hole 18 is provided on the tip side of the cylindrical portion of the lens holder 11. As shown in FIG.

In addition, the camera holder 13 can be divided into left and right at the center portion in the horizontal direction, that is, the circular hole 18 can be divided into a right semicircular portion 18A and a left semicircular portion 18B. The right member has a right semicircular portion 18A (partial holding portion) that opens leftward, a right half of the concave portion 17 (partial holding portion), and a screwing piece 16 that protrudes rightward. While one holder member 14A is formed, the members on the left side are a left semicircular portion 18B (partial holding portion) opened to the right, a left half of the concave portion 17 (partial holding portion), and a screw-fastening piece protruding leftward. 16 and the second holder member 14B. Further, a projection 19 projecting leftward is provided on the lower side of the right semicircular portion 18A on the left end surface of the first holder member 14A (the surface facing the second holder 14B in the assembled state of the camera holder 13). there is Further, a loose insertion hole 20 into which the protrusion 19 of the second holder member 14B can be loosely inserted when the camera holder 13 is assembled is provided above the right semicircular portion 18A on the left end surface of the first holder member 14A. On the other hand, the second holder member 14B has the same shape as the first holder member 14A rotated 180 degrees about the front-rear direction. Therefore, the projection 19 and the loose insertion hole 20 are also provided in the second holder member 14B, and the projection 19 is formed on the right end surface of the second holder member 14B (the surface facing the first holder 14A in the assembled state of the camera holder 13). ), and the loose insertion hole 20 is positioned below the left semicircular portion 18B on the right end surface of the second holder member 14B.

The camera holder 13 can be assembled together with the camera 10. After the first holder member 14A and the second holder member 14B are arranged so as to sandwich the base end side of the lens holder 11 of the camera 10 from both left and right sides. The left end surface of the first holder member 14A and the right end surface of the second holder member 14B are brought into contact with each other while inserting the projections 19, 19 of each other into the loose insertion holes 20, 20 of the other, thereby forming a series of recesses 17 and circular holes. 18 is formed, the base portion 11A of the lens holder 11 is housed in the concave portion 17, and the base end side of the cylindrical portion of the lens holder 11 is positioned in the circular hole 18. As shown in FIG. In the camera holder 13 assembled in this way, the screws 30, 30 are used to screw the screwing pieces 16, 16 corresponding to the screwing portions 31, 31 provided on the inner surface of the front case 2. As the camera holder 13 is fixed, the camera 10 is installed with the lens 5 exposed in the camera window 4 . The loose insertion holes 20, 20 are holes whose diameters increase toward the end face side, allowing the screwing pieces 16, 16 to flex as will be described later, and allowing the screwing pieces 16, 16 to flex. are bent, the projections 19, 19 are kept loosely inserted into the loose insertion holes 20, 20.例文帳に追加

When a strong impact is applied to the intercom cordless handset 1 as described above in a direction in which the lens 5 is pushed into the main body case, the screwing pieces 16, 16 bend rearward as shown in FIG. Then, the camera 10 is moved into the body case while being held by the camera holding portion 15 . At this time, the projection direction of the screwing pieces 16, 16 from the camera holding portion 15 is the horizontal direction, which is perpendicular to the direction in which the lens 5 is pushed into the body case. 16, 16 will effectively flex backwards. Therefore, the deformation of the screwing pieces 16, 16 and the movement of the camera 10 mitigate the impact, and the camera 10 is prevented from being damaged. Also, the camera 10 once moved into the main body case moves to the outside of the main body case (the side where the lens 5 is exposed) by the elastic force of the screwing pieces 16, 16 and returns to the initial position. By maintaining the loosely inserted state of the projections 19, 19 in the loosely inserted holes 20, 20 when the camera 10 is moved in the front-rear direction, the camera holder 13 does not move even after the camera 10 returns to the initial position. A proper positional relationship between the first holder member 14A and the second holder member 14B is maintained. Therefore, for example, when the camera 10 returns to the initial position, there is no problem that one of the holder members is not in the proper position and the camera 10 rattles at the initial position.

According to the intercom slave unit 1 having the above configuration, the camera holder 13 is composed of the first holder member 14A and the second holder member 14B, and the holder members 14A and 14B hold a part of the camera 10. A portion of the circular hole 18, a portion of the recess 17, and a screwing piece 16 are provided. When an impact is applied to the lens 5 in a direction in which it is pushed into the main body case, the screwing pieces 16 of the holder members 14A and 14B are bent, so that the camera 10 is held by the camera holding portion 15. It is designed to move to the inside of the main body case to reduce the impact. Therefore, damage to the camera 10 when the lens 5 is impacted can be suppressed. In addition, there is no need to separately install a member such as a coil spring that is specialized for suppressing damage to the camera 10 as in the conventional art. Therefore, the manufacturing work is simple, and the number of kinds of parts is small, so that the cost can be suppressed.

Furthermore, projections 19 and loose insertion holes 20 are provided on the first holder member 14A and the second holder member 14B, respectively. At the same time, since the projections 19, 19 are kept loosely inserted into the holes 20, 20 even when the camera 10 is moved, the camera 10 moves inward of the main body case when the impact is applied. Then, when the elastic force of the screwing pieces 16 returns to the initial position again, the positional relationship between the first holder member 14A and the second holder member 14B in the camera holder 13 is maintained appropriately. Therefore, for example, when the camera 10 returns to the initial position, the first holder member 14A (or the second holder member 14B) is not in an appropriate position, and the camera 10 does not shake at the initial position. .

It should be noted that the intercom device according to the present invention is by no means limited to the aspects of the above-described embodiments, and not only the overall structure of the intercom device but also the structure for preventing damage to the camera deviates from the gist of the present invention. It can be appropriately changed as necessary within the range of not doing so.

For example, in the above embodiment, the camera holder is composed of a plurality of holder members. 23 can also be used. The camera holder 23 includes a camera holding portion 25 and a screw-fastening piece 26. The camera holding portion 25 includes a concave portion 17 for accommodating the base portion 11A of the lens holder 11, a lens A circular hole 18 through which the base end side of the cylindrical portion of the holder 11 penetrates is provided. The camera 10 is held by the camera holder 23 in the same state as in the above embodiment, and the camera holder 23 is fixed to the screwing portion 31 using the screws 30 . In addition, in FIGS. 6 and 7, the same reference numerals are assigned to the same components as in the above-described embodiment.

Also in the interphone device employing the camera holder 23, when the lens 5 receives an impact in the direction of being pushed into the main body case, the screwing piece 26 of the camera holder 23 bends, thereby causing the camera 10 to move from the camera. While being held by the holding portion 25, it moves inside the main body case to absorb the impact. Therefore, as with the intercom slave unit 1 of the embodiment, damage to the camera 10 when the lens 5 is impacted can be suppressed. In addition, there is no need to separately install a member specialized for suppressing damage to the camera 10, such as a coil spring, as in the conventional art. Therefore, the manufacturing work is simple, and the number of kinds of parts is small, so that the cost can be suppressed.

As another modification, in the above embodiment, the camera holder is made up of two holder members, but of course it may be made up of three or more holder members. It is also possible to appropriately change the design as to what shape it should be.
Further, in the above embodiment, the end surfaces of the two holder members are brought into contact with each other, but it is also possible to adopt a configuration in which a gap is generated between the holder members (the two holder members do not come into contact with each other). is.
Furthermore, each holder member may be provided with a plurality of fixing pieces (for example, the first holder member may be provided with a first screwing piece projecting upward to the right and a second screwing piece projecting downward to the right). is also possible. It goes without saying that a plurality of fixing pieces may be provided for the camera holder made of one member as in the modification above.

Furthermore, the projecting direction of the fixing piece does not have to be the left-right direction. can be changed in design as appropriate. As described in the embodiments, the most effective projection direction of the fixing piece is the direction perpendicular to the direction in which the lens is pushed into the body case when the camera holder is fixed inside the body case. can also be said to be parallel to the surface of the case).
In addition, although the above embodiment describes an intercom slave unit, the present invention is such that a camera having a lens is installed inside the main body case via a camera holder with the lens exposed on the surface of the main body case. As long as this is done, it can be suitably adopted for other intercom equipment such as an intercom main unit and an entrance hall.
