FIG. 2 is a conceptual diagram showing a state where the handset 21 of such a cordless telephone device is installed on a wall 50.
As described above, the magnetic plates 11a and 11b provided on the back surface of the body of the housing 22 of the handset 10 and the metal plate 51 made of, for example, Fe fixed to the wall 50 are attracted to the handset. 10 can be supported by a wall 50. The metal plate 51 may be of any type as long as it can be attracted to the magnetic plates 11a and 11b by magnetic force. The wall 50 is made of the magnetic plates 11a, 1
If the magnetic plate 1b can be attracted by magnetic force, the metal plate 51 is of course unnecessary.

As described above, in the cordless telephone device of the present embodiment, the handset 10 can be supported on the wall 50 only by attaching the metal plate 51 to the wall 50 in advance, so that the interior of the house can be manufactured at low cost. Handset 10 at multiple locations
Can be installed on the wall 50, and no construction is required. Further, since the magnetic plates 11a and 11b and the metal plate 51 are used as support means for supporting the handset 10 on the wall 50, the handset 10 can be sufficiently firmly adsorbed to the wall 50, and The handset 10 can be removed from the wall 50 very easily.

Further, in this manner, the handset 10 is mounted on the wall 5.
When the hook switch 12 is supported at 0, the hook switch 12 is pushed to the back side of the body of the housing 22 and is turned off. on the other hand,
When the caller removes the handset 10 from the wall 50,
This hook switch 12 is turned on.

FIG. 3 is a block diagram showing an electric circuit system of the handset 10.

In the cordless telephone having the above configuration, when a call is to be made, the caller first removes the handset 10 from the wall 50. As a result, the hook switch 12 is turned on. The control unit 14 receives the signal from the hook switch 12 and receives the signal from the receiving circuit 16 and the transmitting circuit 1.
7 and the dial button 26 are made operable. As a result, the signal obtained by the caller operating the dial button 26 and the signal converted from the sound by the microphone circuit 17 are transmitted to the main unit 31 by the antenna 23 via the control unit 14 and the modulation / demodulation circuit 13. Can be sent to The signal sent from the main unit 31 is sent to the speaker circuit 16 via the modulation / demodulation circuit 13 and the control unit 14, and is converted into sound by the speaker circuit 16. In this way, it is possible to talk with the other party.

When the call is terminated, the caller places the magnetic plates 11a, 11b provided on the handset 10 on the wall 50.
The hook switch 12 is pushed to the rear side of the body of the housing 22 and is turned off when the metal plate 51 is fixed to the metal plate 51 fixed to the housing 22. The control unit 14 receives the signal from the hook switch 12, and sets the receiving circuit 16, the transmitting circuit 17, and the dial button 26 to a state in which the operation is stopped.

On the other hand, when the cordless telephone of this embodiment receives a call from another telephone, the control unit 1
4 operates the calling speaker 15 to call the caller. In response, the caller places the handset 10 on the wall 5
When it is detached from 0, the hook switch 12 is turned on.
The control unit 14 receives the signal from the hook switch 12, and sets the receiving circuit 16 and the transmitting circuit 17 to an operable state. This allows the caller to talk with the other party.

The operation at the end of the call is the same as in the above case.

As described above, according to the cordless telephone device according to the present embodiment, when the handset 10 is supported by the wall 50, the hook switch 12 is turned off and the wall 5 is turned off.
Since the hook switch 12 is turned on when it is not supported by 0, there is no need for the caller to operate the hook switch 12 and therefore, the operability at the start and end of the call is improved. And troublesomeness can be eliminated. Also, the magnetic plates 11a, 11
b allows the handset 10 to be sufficiently firmly adsorbed to the metal plate 51, and the magnetic plate 11 of the handset 10
Since the hook switch 12 is turned on and off depending on whether or not the a and 11b are attracted to the metal plate 51, the handset 10 comes off the metal plate 51 on the wall 50, and the caller's It is possible to prevent the hook switch 12 from being turned on against the intention.
However, if there is no possibility that the hook switch 12 will be turned on against the intention of the caller, the handset 10 is placed with the hook switch 12 down, and the hook Of course, the switch 12 may be turned off.

The shape and the like of the handset 10 are not particularly limited. FIG. 4 shows another example of the shape of the handset 10 of the cordless telephone device according to the present invention. In the figure, components denoted by the same reference numerals as in FIG. 2 indicate the same components as those in FIG. Handset 10 shown in FIG.
According to the main body shape, the antenna 23 can be sufficiently separated from the wall 50, so that when the cordless telephone device receives a call from another telephone device, the main body 31
Therefore, there is no possibility that the reception of the radio wave from the telephone is obstructed, and therefore, it is effective in avoiding the inconvenience that the ringing sound is not generated even though the call is received from another telephone device.

Further, in the cordless telephone device of this embodiment, as a support means for supporting the handset 10 on the wall 50, the magnetic plate 11 provided on the back of the body of the housing 22 is used.
Although the metal plate 51 fixed to the a and 11b and the wall 50 is used, it is a matter of course that other supporting means may be used. For example, a part of the body rear surface of the housing 22 may be formed of a metal plate, and a magnetic plate may be fixed to the wall 50.
Further, a magnetic plate on a donut is provided in place of the magnetic plates 11a and 11b, and a hook switch 1 is provided in a central hole of the magnetic plate.
2 may be provided. Further, the handset 10 may be supported on the wall 50 by a method other than magnetic force.

The structure and principle of the hook switch 12 are not particularly limited. For example, a magnetic sensor may be used.

When the handset 10 is supported by the wall 50, the magnetic plates 11a, 11b are in contact with the metal plate 51, so that the metal plate 51 is magnetized. Therefore,
By detecting the state of magnetization of the metal plate 51 using a magnetic sensor, it is possible to determine whether the handset 10 is supported by the wall 50 or not. In this case, unlike the case where a mechanical switch such as the hook switch 12 described above is used, it is possible to prevent a caller from accidentally turning off the hook switch.

In addition, it goes without saying that the hook switch 12 may also be used as a conventional hook switch 27 as shown in FIG.

In this case, for example, the control unit 14 may be configured so as to be in a communication enabled state when at least one of the hook switch 12 and the hook switch 27 is on.
