  Here, there is a case where the main body case 31 is replaced with another main body case 42 due to, for example, a failure of the calling button 37 and the interphone handset 1 is replaced with a new interphone handset 41. At this time, conventionally, it is necessary to replace the entire decorative cover 3. However, according to the present invention, as shown in FIG. 11, the frame member 5 is used as it is, and the panel member 46 is replaced with a panel member 46 having a different position and shape of the central opening 44 and the microphone hole 45 instead of the panel member 4. The decorative cover 43 can be used. The panel member 46 and the panel member 4 are different only in the central opening 44 and the like, and the configurations of the first fixing protrusion 14, the second fixing protrusion 15, the contact piece 9, the screwing piece 11, etc. are exactly the same. It has become.

  If the thickness in the front-rear direction differs from that of the main body case 31 by replacing the main body case 42, the main body case 42 is fixed to the rear surface side of the decorative cover 43 using the second fixing protrusions 15 and 15. That's fine. That is, the metal plate 38 is brought into contact with the left and right portions of the rear surface of the main body case 42, while the second fixing projections 15 and 15 on the left side of the panel member 46, and the second fixing projections 15 and 15 on the right side. The metal fittings 38 are bridged between them, and the metal fittings 38 may be screwed to the second fixing protrusions 15 and 15 (FIG. 12).

  Furthermore, when the main body case 31 is replaced with another main body case 52, there may be a situation where there is no suitable panel member. In such a case, as shown in FIG. 13, the interphone slave unit 51 is used as a mounting case in which the frame member 5 is not assembled to the frame member 5 but only the frame member 5 is assembled to the storage case 6 that houses the main body case 52. What is necessary is just to comprise. In this case, the main body case 52 is fixed to the storage case 6 side through a dedicated mounting base (not shown).

Therefore, since it is not necessary to replace the entire decorative cover 3 as in the conventional case, the replacement work is easy. Further, since the frame member 5 can be reused, there are few wasted parts, the cost can be reduced, and this is preferable from the viewpoint of environmental problems.

  Moreover, when there is no suitable panel member with respect to the main body case 52, the intercom cordless handset 51 can be comprised without attaching a panel member. Therefore, versatility is high and further cost reduction can be achieved.

  Furthermore, in the case where the plate installation portion 18 for attaching the name plate 39 is provided adjacent to the upper side of the attachment opening 17 in the frame member 5, the upper side portion of the panel member 4 and the plate installation portion 18 are provided. In the boundary portion, a part of the upper side portion of the panel member 4 overlaps with the arms 19 and 19 of the frame member 5 in the front and rear, and the upper surface of the part of the panel member 4 and the arms 19 and 19 of the frame member 5 The upper surface is substantially flush with the upper surface. Therefore, the sense of unity between the panel member 4 and the frame member 5 is increased, and the appearance of the intercom handset 1 can be made more beautiful.

Furthermore, screwing pieces 11 and 11 for screwing the panel member 4 to the frame member 5 are protruded rearward from the main body of the panel member 4, and when the panel member 4 is attached to the frame member 5, The screwing pieces 11, 11 of the member 4 are brought close to the bosses 22, 22 from the rear surface side of the frame member 5, and the panel member 4 main body is rotated to the front side so as to be inserted into the mounting opening 17. A part of the upper side of 4 is turned around to the front side of the arms 19 and 19. Therefore, the attachment work of the panel member 4 can be performed very easily.
Furthermore, since the rear surface of a part of the upper side of the panel member 4 is an inclined surface 4a that gradually becomes thinner toward the tip, it is smoothly caught without being caught by the frame member 5 side when it is turned around. Installation work can be promoted.

  In addition, on the rear surface of the panel member 4, two types of fixing protrusions 14 and 15 having different rearward protrusion amounts are provided at the four corners of the panel member 4, and the first fixing protrusions 14 arranged side by side on the upper and lower sides. , 14 in the left-right direction and the distance in the up-down direction of the second fixing projections 15, 15 aligned vertically on the left side and the right side are the same distance, so the first fixing projections 14, 14. The same metal fitting 38 can be used both when the main body case 31 is fixed and when the main body case 42 is fixed using the second fixing protrusions 15, 15. Therefore, the number of parts can be further reduced, and the cost can be further reduced.

  The intercom device according to the present invention is not limited to the aspect of the above embodiment, and the configuration of the main body case of each interphone device as well as the configuration related to the decorative cover side, etc. As long as it does not deviate from the above, it can be changed as necessary.

For example, in the above embodiment, the panel member is configured to be attached from the rear surface side of the frame member, but may be configured to be attached from the front surface side of the frame member.
Moreover, although only two types of panel members are described in the above embodiment, it is naturally possible to prepare three or more types of panel members, and the height of the fixing protrusion for fixing the main body case for each panel member. There is no problem with different sheath types. That is, a dedicated panel member can be prepared for each main body case.

Furthermore, it goes without saying that the presence / absence of the plate installation portion, the configuration relating to the positioning of the panel member and the frame member, the number, size, shape, etc. of the exposure openings provided in each panel member can be appropriately changed.
In addition, although the interphone slave unit has been described in the above embodiment, the intercom device of the present invention is a collective entrance as long as the main body case is stored in a mounting case having a decorative cover and a storage case. The present invention can be favorably applied to other interphone devices such as a machine.
