[0007]
[Means for Solving the Problems]
In order to achieve such an object, an interphone master unit according to the present invention is captured by a call operation unit having a call operation unit for performing a call operation when a call is made by a visitor at a door station having a camera and a camera at the time of calling. and upper case is formed by a monitor unit having a monitor unit for demarcating leaving the image of the visitor with, and a lower case having a terminal portion for performing wiring of the entrance door station, the lower case, the call control unit and A housing for electrically connecting the monitor unit;
The call operation unit and the monitor unit have a connector for electrical connection with the lower case,
The housing is arranged in the lower case so as to be shifted from each other,
A telephone operation unit and a monitor unit are attached to the lower case so that they can be replaced on the left and right sides.
[0008]
Further, in the interphone master unit according to the present invention, the call operation unit is configured to answer a call from a visitor in a state where a resident who has hooked off a call from a visitor and responded by making a call and a handset is hooked on. Has a hands-free handset unit with a hands-free call button that makes a hands-free call when answering and ends the call when operated again, and a handset for the resident who responds by hooking off a call from the visitor One of the handset unit and a hands-free unit having a hands-free call button for performing a hands-free call when an operation is performed in response to a call from a visitor and terminating a call when the operation is performed again are selected.
[0009]
According to such an intercom master, the configuration of the device can be appropriately selected for each user, and the connection between the units is simplified.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of an interphone master according to the present invention will be described in detail with reference to the drawings.
[0011]
As shown in FIG. 3, the interphone master unit according to the present invention is connected to an entrance cordless handset 10 having a camera 11, and displays a visitor image captured by the camera 11 when calling from a visitor. And a call operation unit 1a (1b, 1c) for performing a call operation when calling.
[0012]
Here, the call operation unit includes the hands-free handset unit 1a shown in FIG. 1 (a), the handset unit 1b shown in FIG. 1 (b), and the hands-free unit 1c shown in FIG. 1 (c). It is configured by selecting one.
[0013]
As shown in FIG. 1 (a), the interphone master unit according to the present invention is captured by a call operation unit 1a having a call operation unit 5a for performing a call operation when a call is made from a visitor by a front door 10 and a camera 11 when calling. A lower case having an upper case 20 formed by a monitor unit 2 having a monitor unit 6 for displaying an image of a visitor and a terminal unit 4 (FIG. 2 (c)) for connecting the entrance unit 10 to each other. 3, and the call operation unit 1 a and the monitor unit 2 are attached to the lower case 3 so as to be interchangeable left and right.
[0014]
As shown in FIGS. 2A, 2B, and 2C, the lower case 3 includes housings 4a and 4b for electrically connecting the call operation unit 1a and the monitor unit 2 to perform call operation. The unit 1a and the monitor unit 2 have connectors 7a and 7b for electrical connection with the lower case 3. The lower case 3 and the upper case 20 are electrically connected by connecting the housings 4a and 4b and the connectors 7a and 7b.
[0015]
As shown in FIG. 2C, the housings 4a and 4b for electrically connecting the call operation unit 1a and the monitor unit 2 to the lower case 3 are shifted vertically in the lower case 3, respectively. It is positioned and arranged.
[0016]
The hands-free combined handset unit 1a shown in FIG. 1 (a) is in a state in which the handset 5a and the handset 5a are hooked on as a call operation unit for a resident who makes a call by hooking off a call from a visitor.
