FIG. 4 is an explanatory diagram showing the positional relationship between the sensor board 20 and the magnet 16. FIG. 5 is a block diagram of the collective entrance machine 1. As shown in FIG.

First, to explain the structure of the collective entrance unit 1, the collective entrance unit 1 is used as part of a so-called apartment complex intercom system, and has a front case placed on the front side and a rear case placed on the rear side. The main body case 2 has a main body case 2 assembled with a case, and a speaker 3 and a microphone for communicating with an intercom base unit (not shown) installed in each dwelling unit are installed on the front upper part of the main body case 2. 4 (shown in FIG. 5), a camera section 5 for taking an image of the front of the main body case 2, etc. are provided. Further, a touch panel is installed approximately in the center of the front surface of the main body case 2, and serves as an operation section 6 for a visitor to select a dwelling unit to call and to perform a calling operation related to calling a resident. On the other hand, the main body case 2 includes a control unit 7 that controls the main operations of the collective entrance unit 1, such as communication with the intercom base unit, and a control unit 7 that controls the main operations of the collective entrance unit 1, such as conversation operations with the intercom base unit, and a control unit 7 that controls the main operations of the collective entrance unit 1, such as communication with the intercom base unit, and transmits data related to audio and image data from the camera unit 5 to the intercom base unit. A communication section 8 for communicating with is built in. Such a collective entrance machine 1 is installed on the surface of a wall W such as an entrance of a housing complex as will be described later, and a visitor operates the operation unit 6 to specify the dwelling unit to be called. When the calling operation is performed, the intercom base unit of the corresponding dwelling unit is called, and the camera unit 5 is activated to photograph the visitor. Note that 9 is a decorative cover attached to the front of the main body case 2.

Next, the anti-theft function of the collective entrance machine 1 and the installation structure of the collective entrance machine 1 will be explained.
A sensor board 20 on which a magnetic sensor 11 (shown in FIG. 5) is mounted is installed inside the main body case 2 of the collective entrance device 1. (not shown). That is, the control unit 7 is capable of detecting magnetism using the magnetic sensor 11.

Moreover, the collective entrance machine 1 as described above is installed on the surface of the wall W via the mounting box 12 and the fixed frame 13. The mounting box 12 is buried in the wall as in the conventional case, and has an upper plate, a lower plate, a back plate, and left and right side plates, and is shaped like a rectangular box with an opening at the front. It is said to be large enough to accommodate. Furthermore, mounting pieces 14 for fixing the fixed frame 13 are installed on the inner surfaces of the left and right side plates of the mounting box 12. On the other hand, the fixed frame 13 is a metal rectangular frame body having an upper side, a lower side, and both left and right sides. The size is such that it can be accommodated in the mounting box 12 in such a manner that it can be accommodated in the mounting box 12 in such a manner as to fit along the respective surfaces. Further, fixing pieces 15, 15 for screwing the fixing frame 13 to the mounting piece 14 are provided on both left and right sides of the fixing frame 13. Further, fixing holes 18 for screwing the main body case 2 are formed in both upper and lower sides of the fixing frame 13, respectively. In addition, a magnet holder 17 that holds the magnet 16 is attached to the lower side of the fixed frame 13.

The installation of the collective entrance device 1 on the surface of the wall W using the mounting box 12 and fixed frame 13 may be performed as follows. First, the mounting box 12 is buried in the wall W, and then the fixing frame 13 is fixed to the mounting box 12. Next, the main body case 2 is fitted into the fixed frame 13, and the main body case 2 is screwed to the fixed frame 13. Finally, by attaching the decorative cover 9 to the front of the main body case 2, the installation work of the collective entrance device 1 on the surface of the wall W is completed. In this installed state, the magnetic sensor 11 on the sensor board 20 and the magnet 16 face each other in the front and back, and the controller 7 can detect the magnetism of the magnet 16.

In the collective entrance machine 1 installed as described above, the control unit 7 constantly monitors the magnetism of the magnet 16 using the magnetic sensor 11. Therefore, if a malicious person or the like tries to remove the collective entrance unit 1 from the fixed frame 13, the positional relationship between the magnetic sensor 11 and the magnet 16 will change, so the control unit 7 Based on this, the situation can be detected. Therefore, the control unit 7 operates the speaker 3 to emit a warning sound to notify the surroundings that there is a risk of theft.

According to the collective entrance machine 1 having the above configuration and the installation structure of the collective entrance machine 1, the magnet holder 17 that holds the magnet 16 is attached to the fixed frame 13, while the main body of the collective entrance machine 1 A magnetic sensor 11 capable of detecting the magnet 16 is built in the case 2 at a position facing the magnet 16 . The control unit 7 that controls the main operations of the collective entrance machine 1 constantly monitors the magnetism of the magnet 16 using the magnetic sensor 11, and for example, if the collective entrance machine 1 is about to be removed from the fixed frame 13, etc. When the positional relationship between the magnetic sensor 11 and the magnet 16 changes, the speaker 3 is activated to emit a warning sound. Therefore, theft of the collective entrance machine 1 installed on the surface of the wall W can be effectively prevented. Furthermore, since the conventional anti-theft function uses the speaker 3 and fixed frame 13, the configuration can be rationalized and realized at low cost, and the collective entrance unit 1 can be made smaller. be able to.

The intercom device and the installation structure of the intercom device according to the present invention include not only the overall structure of the intercom device but also the structure of the mounting box and fixing frame, etc., as necessary within the scope of the invention. It can be changed as appropriate.

For example, although the above embodiment describes the installation of a collective entrance device, the present invention can be suitably employed as an installation structure for other intercom devices such as an intercom slave device, and other intercom devices.
Furthermore, in the above embodiment, the magnet holder is attached to the lower side of the fixed frame, but the magnet holder may be attached to the side or upper side of the fixed frame, or the magnet holder may be attached to the mounting box instead of the fixed frame. It is also possible to attach the magnet or embed a separate magnet in the wall.

Furthermore, there is no problem in configuring the fixed frame to be monitored at a plurality of locations, such as by attaching magnet holders to the upper and lower sides of the fixed frame, respectively.
In addition, in the above embodiment, a speaker is provided as a warning means, and the speaker emits a warning sound, but the type of member to be provided as the warning means, the number of warning means, etc. may be determined as appropriate. Design changes are possible. For example, a dedicated lamp may be provided, and the control unit may blink the lamp based on the detection result by the magnetic sensor.
