Description

Description: TECHNICAL FIELD The present invention relates to a telephone device having a hands-free function and a mute function.

[Prior Art] Conventionally, a telephone exchange system controls the function of a telephone according to a command from a main device that controls the entire system.

For example, regarding the mute function, information on the user pressing the mute button is once notified from the telephone to the main unit, a command for setting or canceling the mute is transmitted from the main unit to the telephone, and the mute function is executed.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, since the mute state is simply switched by pressing the mute button, for example, the mute function is provided not only in the microphone in the hands-free mode but also in the handset transmitter. The following inconveniences occur in telephones that are also effective.

In other words, if the user wants to talk on the handset from a state in which mute is enabled in the hands-free call state, simply raising the handset does not cancel mute, and presses the mute button again. Must be released from the mute state.

Therefore, in this case, two operations of raising the handset and pressing the mute button are required, and there is a disadvantage that the operation is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a telephone device capable of appropriately executing or canceling a mute function in a call state using a hands-free function and a call state in which a normal handset is lifted, thereby improving operability. .

Means for Solving the Problems The present invention relates to a telephone device having a microphone and a speaker for hands-free calling and a handset,
Mute instructing means for instructing mute setting and cancellation,
Microphone for hands-free calling, setting of mute setting of the mute instructing means of the handset transmitter, invalid, based on an instruction of cancellation, setting means to set to valid,
The setting means cancels the mute by raising the handset if the microphone for the hands-free call is disabled based on the mute setting instruction of the mute instruction means during a hands-free call. Thereafter, when returning to the hands-free call, the microphone for the hands-free call is set to be invalid based on the setting of the mute of the hands-free call instructed by the mute instructing means.

[Operation] In the present invention, in a telephone device capable of setting a microphone for a hands-free call and a handset transmitter to be invalid or valid, a mute setting is instructed during a hands-free call, and the microphone is turned on. When the handset is disabled and listening to the voice of the other party, the mute is automatically released by raising the handset to talk to the other party, so that there is no need to further instruct the cancellation of the mute. Also, when returning to the state of listening to the other party's voice in a hands-free state by disabling the microphone, the microphone is automatically disabled, so that there is no need to further instruct mute setting. Therefore,
Operability can be improved.

Embodiment FIG. 1 is a block diagram showing a configuration of a main unit 2 of a key telephone apparatus and a telephone 20 according to an embodiment of the present invention.

The main device 2 includes an external line interface 3 for detecting an incoming call from the external line 1 and transmitting a dial palace, and an external line,
A telephone line switch 4 for exchanging / connecting an extension, a sound source, etc., an extension interface 5 for accommodating a telephone 20, a control device 6 for controlling the system, a presence / absence of mute release when the hands set is raised, and a case for the handset raised It has a RAM 7 for storing a mute state and other information necessary for operating the present system, a ROM 8 for storing a program for determining the operation of the control device 6 and the like, and a sound source 9.

On the other hand, the telephone 20 transmits the voice information and the control information to the main unit 2.
, A speech network 22 for closing a line, a handset 23 for transmitting and receiving, a speaker 24 for receiving in a hands-free call, and a microphone 25 for transmitting. A control device 26 for controlling the operation of the telephone, a dial button 27 for performing dial input, a function button 28 capable of arbitrarily assigning a specific meaning on the system under the control of the main device 2, and a function button 28. And a display device 30 for visualizing the dialed numbers and the like under the control of the main device 2.

In this embodiment, a mute function is assigned to the function button 28, and mute control is performed according to a procedure described later.

To assign the mute function to the function button 28, first perform a special number operation indicating the work of assigning the function button to the dial button, then press the corresponding function button, and finally, enter the code corresponding to the mute. Enter using the dial buttons.

With such an operation, the mute function is assigned to the function button 28, and the mute can be set / released every time the button 28 is pressed thereafter.

The LED 29 is turned on / off in accordance with the button operation, and the operation state is displayed.

Next, a description will be given of mode selection for executing mute release when the handset is raised.

This mode selection is also performed by first performing a special number operation using the dial buttons and then pressing the dial button "1" or "0". That is, if "1" is pressed after the operation of the special number, a mode in which mute is forcibly released when the handset is raised is selected, and if "0" is pressed, a mode in which mute is not forcibly released when the handset is raised is selected. The system stores this selection information in the RAM 7 for each telephone.

FIG. 2 is a schematic diagram for explaining each state in this embodiment, that is, a transition of a handset state, a current mute state, and a mute state at the time of on-hook.

Here, control in the case where the selection information is set to forcibly cancel mute when the handset is raised will be described.

The above state transitions are caused by the on-hook / off-hook operation of the user and the pressing of the mute button.
Hereinafter, the state in which the handset is up is called off-hook, and the state in which the handset is down is on-hook.

For example, it is assumed that the user is talking in a hands-free state (on-hook state) with the microphone enabled (mute off). This case corresponds to the state number S1 in FIG.

At this time, when the mute button (function button 28) is pressed so as not to output sound, the current mute state is turned on, and the mute state at the time of on-hook is turned on, and the state shifts to state S2.

If the user goes off-hook in S2, the mute is released when the user goes off-hook, so the current mute state is turned off and the process proceeds to S5.

That is, the user can release the mute by raising the handset even though the mute is on. However, this is temporary, and if you go on-hook again in this state, the mute on state S2
Return to

In this way, regardless of the current mute state, the mute can be released by going off-hook and returning to the set state by going on-hook.

If the setting is not such that the forcible cancellation is performed when the handset is raised, the mute control is performed only by the mute button 28 as in the conventional example.

Note that the present invention is not limited to the above-described embodiment, and various modifications are possible.

For example, the current mute state may be indicated on the display device 30 instead of the LED 29 attached to the function button 28.

[Effects of the Invention] As described above, according to the present invention, in a telephone device capable of setting a microphone for a hands-free call and a transmitter of a handset to be invalid or valid, the present invention provides By instructing mute settings, disabling the microphone and listening to the other party, raising the handset to talk to the other party eliminates the need for further instructions to cancel mute, and If you want to disable and return to listening to the other party's hands-free,
It is not necessary to further instruct mute setting, and operability can be improved.
