[0012] The collective entrance unit 1 is installed on the wall of the main entrance of an apartment house as part of a so-called apartment house intercom system, and includes an entrance unit main body 2 provided with a display / operation unit 3 having a function as a touch panel, and a synthetic resin decorative cover 4 assembled to the entrance unit main body 2 in a state where the display / operation unit 3 of the entrance unit main body 2 is exposed. Further, a microphone unit 5 and a speaker unit 6 for communication are provided on the front surface of the entrance unit main body 2, and a camera unit 7 for imaging the front is also provided. Then, when the display / operation unit 3 is operated by a visitor to specify the apartment to be called, and a call operation is performed, the collective entrance unit 1 calls the intercom master unit (not shown) of the corresponding apartment and operates the camera unit 7 to photograph the visitor.

[0013] Here, the front structure of the collective entrance unit 1 in the present invention will be described. The makeup cover 4 integrally includes a front plate 11 that is substantially rectangular in a front view, an upper plate 12 that extends rearward from the upper edge of the front plate 11, a lower plate 13 that extends rearward from the lower edge of the front plate 11, a left side plate 14 that extends rearward from the left side edge of the front plate 11, and a right side plate 15 that extends rearward from the right side edge of the front plate 11, and is formed in a box shape that opens at the rear. Also, a rectangular opening that is long in the vertical direction is provided in a substantially central portion of the front plate 11, and the opening serves as a window 16 for exposing the display / operation unit 3 of the entrance machine body 2.

[0014] On the other hand, the entrance machine body 2 includes a main body case formed by assembling a front case 21 and a rear case 22. And inside the main body case, a liquid crystal display device 23 that constitutes the display unit / operation unit 3, a liquid crystal cover member 24 that has insulation and is assembled so as to cover the rear of the liquid crystal display device 23, a microphone 25 that constitutes the microphone unit 5, a speaker 26 that constitutes the speaker unit 6, and a control board 27 that controls the operation of the entrance machine body 2 are installed.

[0015] Also, on the front surface of the front case 21, ribs that protrude forward are peripherally provided in a rectangular frame shape. These ribs include an upper rib 31 that extends in the left-right direction at the upper part of the front case 21, a lower rib 32 that extends in the left-right direction at the lower part, a left rib 33 that extends in the vertical direction so as to connect the left ends of both ribs 31 and 32, and a right rib 34 that extends in the vertical direction so as to connect the right ends. And the space surrounded by such ribs functions as a glass plate mounting portion for fitting a glass plate 35 that constitutes a capacitive touch panel. Note that the ribs have substantially the same vertical length and horizontal width as the window 16 of the makeup cover 4, and when the makeup cover 4 is assembled to the front surface of the entrance machine body 2, the ribs are positioned adjacent to the opening edge of the window 16. Also, a display opening 45 for exposing the screen of the liquid crystal display device 23 is provided at a location inside the front case 21 that becomes the glass plate mounting portion.

[0016] Furthermore, a speaker grid 36 is provided in the upper right corner of the glass plate 35 to signal sound emitted from the speaker 26 to the front of the main entrance unit 1. In addition, a cylindrical speaker mounting section 37 for installing the speaker 26 is provided on the rear surface of the front case 21, on the back side of the speaker grid 36. Moreover, a speaker opening 42 is provided in the upper right corner of the front of the front case 21, within the glass plate mounting section, to expose the space inside the speaker mounting section 37 to the front of the front case 21. In addition, a notch is provided at the upper end of the right rib 34, and this notch exposes the space behind the glass plate 35 within the glass plate mounting section to the right side of the front case 21. Therefore, the opening formed by cutting out the right rib 34 communicates with the space inside the speaker mounting section 37, particularly the space in front of the speaker 26, via the speaker opening 42. Therefore, the notch at the upper end of the right rib 34 functions as a speaker hole 38 for signaling sound emitted from the speaker 26 to the front of the main entrance unit 1.

[0017] On the other hand, a short notch is provided in the left rib 33 at approximately the center in the vertical direction, and a reset switch 39 for resetting the settings of the main entrance unit 1 is provided within this notch. This reset switch 39 is located behind the front end of the left rib 33. Furthermore, on the rear surface of the front case 21, a cylindrical microphone mounting section 40 for installing a microphone 25 is provided on the back side of the lower left corner of the glass plate mounting section, that is, on the rear side of the glass plate 35. In addition, a microphone opening 43 is provided in the lower left corner of the front of the front case 21, within the glass plate mounting section, to expose the space inside the microphone mounting section 40 to the front of the front case 21. Moreover, a notch is also provided at the lower end of the left rib 33, and this notch exposes the space behind the glass plate 35 within the glass plate mounting section to the left side of the front case 21. Therefore, the opening formed by cutting out the lower end of the left rib 33 communicates with the space within the microphone mounting section 40, particularly the space in front of the microphone 25, via the microphone opening 43. Thus, the cutout at the lower end of the left rib 33 functions as a microphone hole 41 for collecting sound emitted in front of the main entrance unit 1 into the microphone 25.

[0018] The decorative cover 4 is assembled so as to cover the entrance unit body 2 from the front, with the ribs inserted into the window 16 from the rear. By assembling it in this way, the ribs are positioned along the opening edge of the window 16 as described above, and the ribs protect the glass plate 35 from coming into contact with the decorative cover 4. However, the notches provided in the left and right ribs 33 and 34 allow the speaker hole 38 and microphone hole 41, which are sandwiched between the glass plate 35 and the opening edge of the window 16 from the left and right, to open to the front of the entrance unit 1, and the reset switch 39 can be operated from the front of the entrance unit 1.

[0019] In the multi-unit entrance unit 1 having the above configuration, the front of the main body case of the entrance unit body 2 is provided with ribs that protrude forward, and the area surrounded by the ribs is used as a glass plate mounting area for fitting the glass plate 35, so that when the decorative cover 4 is assembled to the entrance unit body 2 the ribs are positioned along the opening edge of the window 16. Furthermore, on the rear surface of the front case 21, a cylindrical speaker mounting area 37 and a microphone mounting area 40 are provided at the rear side of the glass plate 35, with a speaker 26 installed in the speaker mounting area 37 and a microphone 25 installed in the microphone mounting area 40. In addition, a speaker opening 42 is provided in the area within the glass plate mounting area on the front of the front case 21 to expose the space inside the speaker mounting area 37 to the front of the front case 21, and a microphone opening 43 is provided to expose the space inside the microphone mounting area 40 to the front of the front case 21. In addition, a portion of the right rib 34, which constitutes the rib, is cut out, and the opening formed by this cutout is configured to communicate with the space in front of the speaker 26 within the speaker installation section 37 via the speaker opening 42. This allows the cutout in the right rib 34 to function as a speaker hole 38 for signaling sound emitted from the speaker 26 to the front of the main entrance unit 1. Similarly, a portion of the left rib 33, which also constitutes the rib, is cut out, and the opening formed by this cutout is configured to communicate with the space in front of the microphone 25 within the microphone installation section 40 via the microphone opening 43. This allows the cutout in the left rib 33 to function as a microphone hole 41 for collecting sound emitted in front of the main entrance unit 1 into the microphone 25. In this way, the cutouts provided in the ribs that surround and protect the glass plate 35 are used as communication holes for making calls, thus streamlining the structure of the front of the main entrance unit 1.

[0020] Furthermore, the left rib 33 has another cutout, and a reset switch 39, which can be operated by pushing it in from the front of the main case, is provided within this cutout. By using the cutout in the rib that surrounds and protects the glass plate 35 to install the reset switch 39, the structure of the front of the main entrance unit 1 can be further streamlined.

[0021] Furthermore, the intercom equipment according to the present invention can be modified as necessary, without departing from the spirit of the present invention, not only in terms of the overall configuration of the intercom equipment, but also in terms of the configuration of ribs and notches provided in ribs.

[0022] For example, in the above embodiment, the notch in the rib is used for both the speaker hole and the microphone hole, but there is no problem if the notch in the rib is used for only one of the communication holes. Furthermore, the shape of the glass plate that makes up the touch panel can be modified as needed, and the shapes of the windows and ribs can also be changed accordingly. Naturally, the position of the notches in the ribs can also be changed as needed according to the position of the communication device.

[0023] Furthermore, although the above embodiment provides a touch panel that also functions as an operating unit on the main body case, there is no problem in providing a display unit that does not function as an operating unit. Furthermore, when installing a touch panel, it is certainly possible to use a resistive touch panel instead of a capacitive touch panel. In addition, the present invention can be suitably applied to other intercom equipment such as intercom sub-units and intercom master units. [Explanation of symbols]
