Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base unit of a cordless telephone device that performs cordless communication with a slave unit.

2. Description of the Related Art As shown in FIG. 4, a cordless telephone device includes a base unit (base set) connected to a line and a slave unit (cordless handset) not connected to a line. And communicates wirelessly with the server.

For this reason, there is an advantage that the slave unit can be installed anywhere as long as communication with the master unit is possible regardless of whether wiring with the master unit is possible or not, as in a conventional external telephone. In addition, since the slave unit is portable, there is an advantage that the slave unit can be used anywhere.

Also, in such a cordless telephone device, if the slave unit can operate only for incoming calls, it is possible to restrict inadvertent outgoing calls from the slave unit. Can be very convenient.

[Problem to be Solved by the Invention] By the way, the control for switching whether or not the above-mentioned slave unit is dedicated to receiving only is performed on the master unit side.

Therefore, conventionally, in order to release a slave from incoming only, it is necessary to always perform a switching operation on the master, such as when using the slave in a location away from the master,
In some cases it was very inconvenient.

According to the present invention, the calling from the slave unit is restricted for a predetermined time after the operation means is operated, and the parent unit notifies the operator that the calling from the slave unit is restricted. It is an object of the present invention to provide a cordless telephone device base unit that can be used.

[Means for Solving the Problems] The present invention relates to a base unit of a cordless telephone device that performs cordless communication with a base unit, wherein the base unit includes operating means for setting an operation mode of the base unit by an operation of an operator. A display means for displaying that the operation of the slave unit is set by the operation of the operation means when the operation means is operated, and the display means is provided after a predetermined time from the operation of the operation means. Control means for controlling the display means so as to end the display, and after the operation means is operated and the display means performs the display, after the predetermined time, the display means ends the display And limiting means for limiting a call from the slave unit.

[Operation] In the present invention, when the operation means for setting the operation mode of the slave unit by the operation of the operator is operated, it is displayed that the operation of the slave unit is set by the operation of the operation means,
A predetermined time after the operating means is operated, the display means ends the display, and the operating means is operated and the display means performs the display. Until the display is completed, the calling from the slave unit is restricted.

Embodiment FIG. 1 is a block diagram showing a configuration of a base unit of a telephone device according to one embodiment of the present invention.

The master unit of the present embodiment has a CPU 1 for controlling the entire operation,
An audio signal processing circuit 2, a transmission unit 3 for outputting a signal from the parent device to the child device, a reception unit 4 for receiving a signal from the child device to the parent device, and A / D and D / A signal conversion A modem 5 that performs
A Duplexer 6 for separating transmission and reception signals, an operation unit 8 for performing various key inputs, a display unit 7 for controlling the blinking of various display lamps, a memory 9 for storing data, a telephone line connection and the like. A speech network 10 to be performed, a dialer 11 for sending out a dial signal at the time of calling, a tone ringer 12 for sounding a ringing tone, an antenna 13 for wireless communication, a speaker 14 for outputting a ringing tone, and a dedicated time for receiving a handset. And a timer 15 for setting

FIG. 2 is a perspective view showing the appearance of the master unit. On the outer casing of the main unit, a sub-unit operation mode setting button 16 for setting the operation mode of the sub-unit, i.e., the incoming call only mode or the outside line callable mode, and a sub-unit operation mode LED 17 for displaying the set operation mode. Is provided.

The configuration of the slave unit is the same as that shown in FIG. 4, and can be selectively switched to the reception only mode or the outside line outgoing call mode based on the control of the master unit.

Next, an operation in the case of making an outgoing call from a slave unit will be described.

First, when an external line call request signal is output from the slave unit,
The master unit receives a signal from the antenna 13, and determines whether or not the signal is a signal from the slave unit by the Duplexer 6. If it determines that the signal is from the slave unit, the master unit inputs the received signal to the receiving unit 4. The receiving unit 4 separates a control signal (call request, numeric keypad input, etc.) and a voice signal, and sends the control signal to the modem 5.
The audio signal is output to the audio signal processing circuit 2.

Since this is a control signal, it is input to the modem 5 and demodulated, and is input to the CPU 1. When the CPU 1 determines that this is an outside line call request, it instructs the dialer 11 to make a call and outputs a signal to the modem 5 for permitting the slave unit to transmit a dial signal. The modem 5
This is modulated and sent to the transmitting unit 3, where the Duplex
er6 is output as a transmission signal, and the permission signal is transmitted through the antenna 13.

Hereinafter, similarly, a dial signal and an audio signal are exchanged between the master unit and the slave unit, and one operation is performed.

Next, the operation in the case where the slave unit is set to the incoming call only for a limited time by the timer 15 will be described.

 FIG. 3 is a flowchart showing this operation.

In this embodiment, the slave unit operation mode setting button 16
By pressing once, the slave unit is uniformly set to receive only for two hours.

First, when the slave unit operation mode setting button 16 is pressed (S1), the signal is transmitted from the operation unit 7 to the CPU1.

This causes the CPU 1 to set the timer 15 for two hours (S2), and displays the slave unit operation mode LED 17
(S3). The illumination of the slave unit operation mode LED 17 indicates that the slave unit is currently exclusively for receiving a call.

In this state, there is an external line call request from the slave unit, and this is
When U1 receives it, it outputs a signal indicating that the request cannot be made to the slave unit. As a result, the child device operates as an incoming call only device (S4).

When two hours have elapsed (S5), and the timer 15 outputs a signal indicating the elapsed time to the CPU 1, the CPU 1 displays the display unit 8
Then, the sub-unit operation mode LED 17 is turned off to display that the sub-unit has entered the normal mode (S6).

As a result, the slave unit operates as the above-described outside line calling unit (S7).

Also, in the case of an incoming call from an outside line, regardless of the mode, inform the slave unit that the incoming call is from an outside line,
If the handset receives a speech network
The audio signal input to the audio signal processing circuit 2 through 10 is transmitted to the slave unit as it is.

In the above embodiment, the timer 5 is configured differently from the CPU 1. However, if the internal timer of the CPU 1 is vacant, the cost can be reduced by using the timer.

Further, in the above-described embodiment, the time for exclusively setting the slave unit to receiving a call is set to two hours. However, for example, a combination of the slave unit operation mode setting button 16 and the numeric keypad allows the setting time to be input. May be set.
The handset can be made dedicated to receiving calls only when deemed necessary.

[Effects of the Invention] As described above, according to the present invention, when it becomes necessary to temporarily restrict the calling from the child device, the restriction can be immediately performed, and the restriction can be made. Is canceled after a predetermined time, so that it is possible to prevent the calling from the slave unit from being forgotten by being forgotten to cancel the cancellation, and to determine whether the calling from the slave unit is restricted. Person can know at the parent machine.
