It is a transparent plate-like member having a flange 22 and can be fitted into a first storage recess 41 formed in the front surface of the front case 2. Further, a recess 23 recessed forward is provided on the rear surface of the panel body 21, and a spacer member 12 is arranged behind the operating member 11 to cover the recess 23, so that the recess 23 can be used for living. It functions as a space in which a name plate (not shown) on which the name of a person, etc. is written can be stored. Furthermore, a slit 24 is provided on the right side of the flange 22 for inserting and removing a name plate into the recess 23.

The spacer member 12 is a translucent synthetic resin plate that is rectangular in front view, and can cover the recess 23 and is recessed further rearward within the first storage recess 41 of the front case 2. It can be stored in the second storage recess 42 . By being stored in the second storage recess 42, the window 25 opened in the second storage recess 42 can be covered. Further, on the rear surface of the spacer member 12, diffusion printing is applied to diffuse light.

The light guide plate 13 is molded from a transparent synthetic resin, and has a plate main body 13a that is elongated in the left-right direction, and leg portions 13b that are integrally molded on both left and right sides of the plate main body 13a. The surfaces of the plate body 13a and the leg portions 13b (particularly the rear surface of the plate body 13a and the front surface of the leg portions 13b) are textured to diffusely reflect light. Further, the horizontal length of the board main body 13a is approximately the same as the horizontal width of the window 25, while the vertical width of the board main body 13a is approximately 1/4 of the vertical width of the window 25, and there are four When the light guide plates 13, 13, . They are located at their respective locations.

The control board 14 controls the lighting state of the panel part 4, and a holding part 27 is provided on the front surface of the control board 14 to hold the board bodies 13a, 13a, etc. side by side in the vertical direction. There is. Further, on the front surface of the control board 14, on both the left and right outer sides of the holding part 27, and at the rear side of the legs 13b, 13b of each light guide plate 13 held by the holding part 27, there are LEDs 26, 26, respectively. ... is installed.

In constructing the panel section 4, on the rear side of the front case 2, the light guide plates 13, 13, etc. are held on the front surface of the control board 14, and then the plate bodies 13a of the light guide plates 13, 13,... , 13a, etc. are fitted into the window 25, and the control board 14 is installed on the rear side of the front case 2. On the other hand, on the front side of the front case 2, the spacer member 12 is stored in the second storage recess 42, and the operation member 11 is fitted in the first storage recess 41, and the operation member 11 is inserted into the front case. Paste it on the front of 2. Then, the plate bodies 13a, 13a, etc. of the light guide plates 13, 13, etc. are located behind the panel body 21 of the operating member 11, with the spacer member 12 in between, and the leg portions 13b, 13b of each light guide plate 13 are positioned on both sides of the spacer member 12. The panel section 4 is configured with the LEDs 26, 26, . . . positioned at the rear. Note that the rear surface of the spacer member 12 is in contact with the front surface of the plate main bodies 13a, 13a, etc. located within the window 25.

In the panel section 4 as described above, by selectively lighting the LEDs 26, 26, . . ., it is possible to light the LEDs 26, 26, . . . in the three lighting modes described below. Note that the lighting mode in which the panel section 4 is to be lit can be set using a setting switch (not shown).
(1) 4-split mode In the 4-split mode, when the operating member 11 is touched, only the light guide plate 13 located behind the touched part of the four light guide plates 13, 13, etc. is turned on. This mode allows you to In such a 4-division mode, only the LEDs 26, 26, etc. located behind the legs 13b, 13b of the light guide plate 13 to be lit will emit light, but at that time, the light emitted from the LEDs 26, 26, etc. does not substantially affect the light guide plates 13, 13 disposed above and below the light guide plate 13 that is lit. Therefore, the boundary between the light guide plate 13 that is lit and the light guide plates 13 and 13 that are not lit above and below it is clear. Therefore, compared to the case where four light guide plates 13, 13, etc. are combined into one light guide plate, the illuminated areas and unlit areas of the panel body 21 are clearly defined. It will be separated. Therefore, when lighting in the 4-split mode, four name display areas 28D to 28G can be formed in the vertical direction on the panel body 21. For example, when the name display area 28E is touched, the name display area 28E Only the light guide plate 13 located behind is lit, and as a result, only the name display area 28E is lit (FIG. 6(c)).

(2) Two-split mode In the two-split mode, the upper two light guides of the four light guide plates 13, 13, etc. This is a mode in which the light plates 13, 13 are turned on, or the lower two light guide plates 13, 13 are turned on. Even in this two-split mode, the boundary between the light guide plate 13 that is lit and the light guide plate 13 that is not lit is clear for the above-mentioned reason. Furthermore, at the boundary between the lit light guide plates 13, 13, the light is diffused and made uniform by the spacer member 12 interposed between the light guide plates 13, 13... and the operating member 11. Therefore, it becomes less noticeable. When lighting in such a two-split mode, two upper and lower name display areas 28B and 28C can be formed on the panel body 21. For example, when the name display area 28B is touched, the upper two name display areas 28B and 28C are displayed. The light guide plates 13, 13 are lit (specifically, the LEDs 26, 26, etc. located behind the legs 13b, 13b, etc. of the upper two light guide plates 13, 13 are lit), and the name display area 28B is lit (FIG. 6(b)).

(3) Full screen mode In the full screen mode, the entire panel body 21 lights up regardless of where the touch operation is performed. In other words, all four light guide plates 13, 13... will light up in response to the touch operation (all LEDs 26, 26... will emit light), but the boundaries between the light guide plates 13, 13 that are lit is less noticeable for the reasons mentioned above. When lighting in such a full-screen mode, only one name display area 28A is formed on the panel main body 21, and when the panel main body 21 is touch-operated, almost the entire surface of the panel main body 21 (i.e. The name display area 28A) becomes lit (FIG. 6(a)).

According to the intercom handset 1 having the above configuration, the panel section 4 having a function as a name display section has four light guide plates 13, 13, . . . arranged in parallel in the vertical direction, and each light guide plate. A plurality of LEDs 26, 26, . . . are disposed behind the legs 13b, 13b, respectively, and can light up the corresponding light guide plate 13 by emitting light, and a transparent operation covering the front of the light guide plate 13, 13, . It includes a member 11 and a control board 14 on which LEDs 26, 26, . . . are mounted. Depending on the difference in the LEDs 26, 26, etc. that emit light, it is possible to control which of the four light guide plates 13, 13, etc. is lit, and which of the light guide plates 13, 13, etc. are lit. Depending on the difference, it is possible to control which area of the panel body 21 is lit. Therefore, for example, if the front area of each light guide plate 13 in the panel body 21 is made into a name display area 28D to 28G, even if a plurality of names are displayed on the panel body 21 as a whole, the different light guide plates 13 to be lit will be different. Different name display areas 28D to 28G can be lit accordingly, and only the necessary names can be suitably lit.

Also, between the panel body 21 of the operating member 11 and the plate bodies 13a, 13a, etc. of the light guide plates 13, 13, there is a spacer having translucency and printed on the rear surface to diffuse light. A member 12 is interposed. Therefore, when a plurality of adjacent light guide plates 13, 13, . . . This makes it possible to improve the intercom handset 1, which is easy to use.

Note that the intercom device according to the present invention is not limited to the aspects of the above-described embodiments, and the overall configuration of the intercom device as well as the configuration related to the name display section do not depart from the spirit of the present invention. The range can be changed as necessary.

For example, in the above embodiment, four light guide plates are arranged in parallel in the vertical direction, but the light guide plates may be arranged in parallel not only in the vertical direction but also in the left and right direction, or in a grid pattern. There is no problem, and the number is not limited to four.
Furthermore, in the above embodiment, the leg portions are provided on both the left and right sides of the light guide plate, and the light emitting member is placed behind the leg portions, but the light emitting member may be placed behind the main body of the light guide plate. The light emitting members may be arranged on the left and right sides of the light guide plate (a configuration in which light is incident on the light guide plate in the left and right directions), and the design of the positional relationship between the light guide plate and the light emitting members can be changed as appropriate. . It goes without saying that the number of light emitting members arranged on one light guide plate can also be changed as appropriate.

Furthermore, in the above embodiment, the name display section also has a function as an operation section, but the name display section does not have a function as an operation section, and a button that can be pressed is separately provided, etc. The name display section may be configured to light up in response to an operation.
Furthermore, in the embodiment described above, a spacer member is interposed between the operating member 11 and the light guide plates 13, 13, etc., but it is also possible to configure the structure so that no spacer member is provided depending on the application. Yes, even if a spacer member is installed, there is no problem in installing another spacer member such as a spacer member made of synthetic resin with low transparency, rather than a spacer member with diffusion printing as described above. .
In addition, although the above embodiment describes an intercom slave device, the present invention can also be applied to other intercom devices such as a collective entrance device as long as a lightable name display section is provided on the front of the main body case. can be suitably employed.
