DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A hands-free television intercom according to the present invention will be described below with reference to the drawings. FIG.
FIG. 1 is an exploded perspective view showing one embodiment of a hands-free television intercom according to the present invention. In these figures, the hands-free television intercom A of the present invention is
Main body part B provided with a mounting plate B 'on the back surface that can be mounted on a wall surface
In addition, the cover part C is formed in a box shape to be integrated with the front side. The main unit B includes a common sub-circuit board 3, a monitor television 4, and a circuit board 5 in which the call indicator 1 and the microphone unit 2 are arranged close to each other.

On the other hand, on the cover C, a monitor television display window 11 is opened at a position corresponding to the display screen 41 of the monitor television 4, and the periphery of the monitor television display window 11 has a stepped frame portion 11a. The smoke panel 12 is formed on the frame 11a. Further, the cover body C
A call push button 13 is provided in the center of the lower end.

Hereinafter, these will be described in detail. FIG. 2 is a partial perspective view in which a main part of FIG. 1 is enlarged, and FIG. 3 is a schematic explanatory view in which a main part is enlarged. Since the call indicator light 1 is installed immediately below the frame portion 11a of the monitor television display window 11, a general LED can be used, and the call indicator light 1 is provided on the sub-circuit board 3. The frame 11a corresponding to the call indicator light 1 is provided with a small through hole 11b for covering the LED.

Therefore, the light emitted from the call indicator light 1 passes through the small through hole 11b and directly strikes the back of the smoke panel 12, and through the smoke panel 12,
The call indicator 1 can be displayed. The small through hole 1
1b can be easily opened by using a concave portion of a grain (uneven surface) formed in the smoke panel 12.

The microphone unit 2 is provided on the sub-circuit board 3 close to the call indicator light 1 and located at a position just below the edge 11c of the cover C outside the monitor television display window 11. It is installed in. In addition, a through hole 11d for a call is provided in the edge portion 11c corresponding to the microphone portion 2.
Has been established. Therefore, the conversation sound can be directly transmitted to the microphone unit 2.

On the sub-circuit board 3, in addition to the call indicator 1 and the microphone section 2, components for suppressing noise are mounted, and are separated from the main circuit board 5. Therefore, the sub circuit board 3 and the main circuit board 5 are connected to the harness 3
2 is connected. The sub circuit board 3 is fixedly disposed above the main circuit board 5, that is, on the cover C side.

FIG. 4 is a partially enlarged sectional view showing a fixed state of the sub-circuit board 3. As shown in FIG. A hollow rib 1B that opens downward is provided upright at a corner of the main body B, and a mounting hole 2B is formed on the upper surface of the hollow rib 1B. On the other hand, a hollow rib 1C which is opened downward is provided at a corner of the cover body C corresponding to the hollow rib 1C.
A female screw groove 2C is formed on the C inner surface. These hollow ribs 1B and 1C can be formed by slightly cutting a conventional rib, and can hold the sub-circuit board 3 at a desired height position. Therefore, the mounting height can be set according to the type of the call indicator light 1 to be used. In addition, a microphone protection portion 3C is formed adjacent to the hollow rib 2C, into which the microphone portion 2 is inserted.

A mounting hole 31 is formed in the sub-circuit board 3, and the mounting hole 31 is overlapped with the mounting hole 2B (2C) of the main body B and the cover body C so that the sub-circuit board 3 is mounted. The body B and the cover C are sandwiched between the body and the cover.
The sub-circuit board 3 is securely fixed by screwing a mounting screw D for fixing the sub-circuit board 3. The monitor television 4 is of a flat type, and the main circuit board 5 is mounted below the monitor television 4.

The main circuit board 5 is provided with various necessary equipment shown in FIG. 1, 51 is a power supply section, 52 is a speaker section, 53 is a ring volume control switch, and 54 is a control section for image processing. And so on. Further, as shown in the assembly procedure diagram of FIG. 5, a claw 3D for temporarily supporting the sub-circuit board 3 is provided on the inner surface of the cover C corresponding to the sub-circuit board 3, and the sub-circuit board 3 has As shown in FIG. 2, a locking hole 33 locked with the claw portion 3D is formed.

For this reason, as shown in FIG. 5, the engaging claw 33 of the sub-circuit board 3 is temporarily engaged with the claw 3D of the cover C to temporarily support it, and then the cover C is attached to the main body. If it is put on B, both can be easily integrated in a state where they are aligned, and the assemblability is improved. The hands-free television interphone of the present invention configured as described above is used as follows. FIG. 6 is a diagram illustrating the use of the hands-free television intercom A according to the present invention. The method of use will be described with reference to FIG. 1 with reference to FIG. , The image of the visitor is displayed on the panel 12 of the cover C.

When the operator confirms this and wants to respond to the visitor, he presses the call push button 13 below the panel 12, and the call switch 55 in the main body B is turned on. Then, the call indicator light 1 located on one side of the panel 12 is turned on, and the operator is identified as being able to talk. Further, even when the visitor does not press the call button of the camera-equipped door phone, when the operator presses the call push button 13, the call switch 55 in the main body B is turned on, and the The call indicator 1 is turned on to identify that a call is possible.

Then, the operator who has confirmed the call indicator light 1 can respond to a visitor or the like via the speaker of the camera-equipped door phone if he responds to the microphone unit 2 close to the call indicator light 1. .

[0024]

According to the hands-free television interphone according to the present invention, since the call indicator is provided behind the panel of the monitor television display window, a space for installing the call indicator can be secured. Therefore, general LED is not limited to thin chip type LED as call indicator
Can be used, so that a conventional two-color lens can be eliminated, and a P-type mounting a thin chip type LED can be used.
CB can also be made unnecessary.

Therefore, the configuration of the call indicator can be simplified and the cost can be reduced. Further, the call indicator is lit at the back of the panel, that is, within the range of the monitor television display window and in a position close to the monitor television image. The call indicator can be easily checked without moving the.

Further, by providing the microphone portion close to the call indicator light, the call indicator light and the microphone portion can be mounted on a common sub-circuit board separated from the main circuit board, and these are connected by a harness. Therefore, the assemblability can be simplified and the performance can be improved without employing a non-uniform configuration as in the related art. Further, since the sub-circuit board can be temporarily supported by the claws of the cover body, the positioning can be facilitated and the assembling property can be further improved.
