Here, the call indicator lamp 20 of the intercom base unit 1 which is a main part of the present invention will be described in detail.
The call indicator lamp 20 is for informing the user of a call state in the intercom base unit 1 and is provided as a part of the video display unit 4. First, the main structure of the video display unit 4 will be described. The video display unit 4 is built in the main body case so as to be exposed in the video opening 10 opened on the front surface of the main body case. The liquid crystal display device 12 and a panel 11 attached to the front surface of the main body case so as to cover the front side of the liquid crystal display device 12 including the image opening 10 are provided. The panel 11 is a plate formed in a substantially rectangular shape when viewed from the front, and a first transparent portion 11A for visually recognizing an image displayed on the liquid crystal display device 12 is provided at a position near the center. It has been. Further, the periphery of the image opening 10 on the front surface of the main body case is recessed rearward by substantially the same thickness as the panel 11 from the other front surface of the main body case, and the front view is substantially the same shape as the panel 11. A mounting recess 13 is provided, and the panel 11 is fitted into the panel mounting recess 13.

  In addition, a light source opening 23 is formed at the center of the lower end of the panel mounting recess 13, and a cylindrical light guide 21 extends from the light source opening 23 toward the inside of the main body case. The opening 23 is in communication with the inside of the main body case. The light source opening 23 is provided above the lower edge of the panel mounting recess 13 by a predetermined width (here, 0.3 mm) (that is, inside the panel mounting recess 13). That is, the lower surface of the light guide 21 (the opening edge of the light source opening 23) is one step higher than the lower surface (inner peripheral surface) of the panel mounting recess 13, and the step formed between the two is shielded from light. A step 22 is formed. Further, a call indicator LED 31 is installed at a position on the rear side of the light guide 21 in the main body case (position exposed in the light source opening 23). On the other hand, at the lower edge of the panel 11 and covering the front side of the light source opening 23 when the panel 11 is mounted in the panel mounting recess 13, a second light for visually confirming the light emission of the call indicator LED 31.

It is expected that a gap will occur between them. However, the panel 11 and the panel mounting recess 13 are such that the lower edge of the panel 11 (particularly the second transparent portion 11B) is positioned on the front side of the light shielding step portion 22, in other words, the lower edge of the panel 11 and the panel mounting recess 13. The dimensional accuracy is such that the gap with the lower surface of the light does not extend further upward than the light shielding step portion 22. Note that the call indicator LED 31 is mounted on the control board 30 of the intercom base unit 1, and the operation related to lighting / flashing is controlled by a CPU (not shown) mounted on the control board 30. Yes. The control board 30 is also equipped with a switch 32 that detects the operation of the response button 6.

  Then, in the interphone master unit 1 equipped with the call indicator light 20 as described above, the call indicator LED 31 starts blinking when there is a call from the interphone slave unit, and the call indicator light is accompanied by a response operation by the response button 6. The LED 31 is turned on. The light accompanying the blinking or lighting of the call indicator LED 31 is visible from the front side of the main body case through the light guide portion 21 through the light source opening 23 and the second transparent portion 11B. That is, the call indicator light 20 blinks or lights up. At this time, even if there is a gap between the lower edge of the panel 11 and the lower surface of the panel mounting recess 13, the lower edge of the panel 11 and the light shielding step 22 overlap each other, so that a call display It is difficult for light emitted from the LED 31 for the light to leak from the gap.

  According to the intercom base unit 1 having the above-described configuration, the second transparent portion 11B is provided along the lower edge of the panel 11, while the second transparent portion 11B in the panel mounting recess 13 is provided on the second transparent portion 11B. A light source opening 23 communicating with the inside of the main body case is opened at a position to be covered and a predetermined width above the lower edge of the panel mounting recess 13. A light shielding step portion 22 is formed between the inner peripheral surface of the concave portion 13 for use, and the lower edge of the panel 11 and the light shielding step portion 22 that are attached to the concave portion 13 for panel attachment overlap in the front-rear direction. . Therefore, when the call indicator LED 31 incorporated in the main body case so as to be exposed in the light source opening 23 is lit / flashed according to the state related to the call with the interphone slave unit, the light is emitted from the panel 11 and the panel 11. It is difficult to leak from the gap with the mounting recess 13. Therefore, the presence of the gap is not easily emphasized, and the appearance is not impaired. Moreover, since it is not necessary to raise the dimensional accuracy of the panel 11 or the panel mounting recessed part 13 so much, it can be configured at low cost.

Further, in the intercom base unit 1 provided with the response button 6 that can be pushed in adjacent to the lower side of the panel 11, the second transparent portion 11 </ b> B is provided along the lower edge of the panel 11. The call indicator lamp 20 is provided in the vicinity of 6 so that the user can easily determine whether the call indicator lamp 20 is lit / flashing, and in turn the state of the interphone master unit 1 in connection with the call, and has excellent design. The intercom base unit 1 can be used.
Further, the call indicator LED 31 is mounted on the same control board 30 as the switch 32 that detects the pressing operation of the response button 6. Therefore, a rational configuration with a reduced number of parts can be achieved, and the interphone master unit 1 can be downsized.
