Abstract

PURPOSE:To select the line wire and the extension by constituting the equipment so that when off-hook is executed, an off-hook timer operates and the extension or the line wire can be selected, and when its timer becomes time-over, a line wire catching timer operates and the line wire is caught for a prescribed time. CONSTITUTION:A calling party executes one of a call key operation for calling an extension or a dial operation to a line wire, therefore, its signal is transmitted to a master machine M from a slave machine S, and decided to be reception of receiver data. Therefore, it is decided not to be charge-off data, and decided to be in the course of operation of an off-hook timer, therefore, whether call data is received or not is decided. That is, when the slave machine S is detached from a charger, the off-hook timer operates, and in the course of its operation, whether a call key 32 for calling an extension is operated or not is decided. In this case, in the case the call key 32 is operated, an extension call processing is executed. In the case it is decided not to be call data, whether it is dial data or not is decided, and in the case of the dial data, a line wire is caught, a dial signal is sent out, and a processing for stopping the off-hook timer is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cordless telephone device capable of making outside calls and internal calls.

[Prior Art] Generally, cordless telephones are housed in a charger when not in use. When in use, the handset is configured to immediately enter the outside line capture state by removing it from its charger.

[Problems to be Solved by the Invention] However, when making an extension call, there is a problem that the extension call cannot be made unless the user presses the "off" button once to release the outside line and then presses the call button.

[Means for Solving the Problems] In order to solve such problems, the present invention is provided with a function that allows selection of either an internal line or an outside line within a predetermined time.

[Operation] When off-hook is performed, an off-hook timer operates, and while the timer is operating, it is possible to select an internal line or an external line.

When the timer times out, the outside line capture timer operates and captures the outside line for a predetermined period of time.

When the outside line capture timer times out, the outside line is released.

[Example] FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, M is a base unit, 1 is an outside line terminal, 2 is an incoming call detection circuit that detects a ringing signal coming from an outside line, and 3 is a CP.
A relay is controlled by U5, 6 is a 2-wire/4-wire conversion circuit, 7 is a wireless transceiver section, and 11 is an antenna. This main unit is equipped with a speaker 9 and a microphone 10, and a driver 4 enables hands-free calls.

S is a slave unit, which includes a wireless transmitting/receiving unit 37 that transmits and receives radio waves via an antenna 41, a handset 40 that makes calls, a CPU 35 that performs various controls, and an extension calling unit (in this embodiment, the extension is the number of the base unit). a call key 32 for performing hands-free operation (partially hands-free);
Dial 33 and display 3 that send dial signals to outside lines
6. A driver 34 for driving a speaker 39 is provided. When the handset is not in use, it is housed in a dedicated charger (not shown), and charging information is supplied to the CPU 35.

FIG. 2 is a flowchart showing the operation of this device.

When the power is turned on, initial processing in step 100 is performed. When the handset is picked up from the charger that is used, charging off data indicating this is transmitted from the handset to the base unit by radio, so the base unit determines that the handset data has been received in step 101, and turns off charging in step 102. It is determined that it is data. At the time of first use, it is determined in step 103 that the outside line is not on hold, and the off-hook timer start process in step 110 is performed. After other processing not directly related to the present application is performed in step 105, it is determined in step 106 whether or not the off-hook timer time has expired. judge that it has not been done. Next, in step 107, it is determined whether or not the acquisition timer is up. However, as will be described later, this acquisition timer is not operating when the off-footer timer is operating, so step 107 is performed to determine whether the acquisition timer has timed up. I judge that there is no. Therefore, the flow returns to step 101.

In this state, the caller either presses the eject key to emit an extension number or dials an outside line, so the signal is transmitted from the slave unit to the base unit, and in step lot it is determined that the handset data has been received. . Therefore, step 102 is determined not to be charging off data, and step 102 is determined not to be charging off data.
Since step 15 determines that the off-footer timer is in operation, it is determined in step 116 whether or not call data is being received.

That is, when the handset is removed from the charger, the off-hook timer operates, and during this operation, it is determined in step 116 whether or not a call key for calling an extension has been operated. If the call key is operated here, step 11
At step 7, an extension discharge process is performed, and at step 118, the operation of the off-hook timer is stopped. In this case, the extension call calls the hands-free part of the base unit. Thereafter, other processing in step 105, ie, call termination processing at the end of the call, etc., is performed.

If it is determined in step 116 that it is not call data, it is determined in step 120 whether or not it is dial data, and if it is dial data, an outside line is captured in step 121, a dial signal is sent in step 122, and step 120 determines whether or not it is dial data. At step 123, processing for stopping the off-hook timer is performed.

Other processing in step 105, for example, a call termination process at the end of a call, etc., is then performed.

On the other hand, when the handset is removed from the charger, the off-hook timer operates in step 110, and if no operation is performed thereafter, it is determined in step +06 that the off-hook timer has timed up. As a result, outside line acquisition is performed in step 135, and acquisition timer start processing is performed in step 136.

At the beginning of the operation of the acquisition timer, it is determined in step 107 that the acquisition timer has not timed up, and the flow returns to step 101. In this state, the outside line is captured, so the caller can dial. When a dial operation is performed, the signal is transmitted from the handset to the base unit, and in step 101 it is determined that the handset data has been received, in step 102 it is determined that it is not charging off data, and in step 115 it is determined that the off-hook timer is not operating. At step 125, it is determined that the capture timer is operating, and at step 130, it is determined that the dial has been pressed.

For this reason, a dialing signal is sent out in step 131,
At step 132, processing for stopping the acquisition timer is performed.

At step 136, a capture timer start process is performed;
If no dial operation is performed after that, step 10 will occur.
At step 7, it is determined that the acquisition timer has expired, and at step 140, the outside line is released.

FIG. 3 shows another embodiment, in which a 2W telephone T is connected to the main unit M and the 2W telephone T is used as an extension telephone, and the overall control operation is the same as that in FIG. Although it is the same, the extension calling process in step 117 called the hands-free function in the case of FIG.
In the case of Fig. 3, the difference is that the 2W telephone T is called 7. In other words, in the case of an extension call process, the relays 2W and co operate, and the contacts 2W and co switch in the opposite direction to that shown in the figure, supplying call current. A talking current is sent out from the circuit 21, and a ringing signal is sent out by the ringer 22. And 2 lines 4
The line converter 6 is switched to the 2W telephone T side. Other operations are the same as in the case of FIG.

The above embodiment has been described assuming that the slave unit has a dedicated charger, but the base unit may also be provided with a charging unit, and in this case, step 102 detects changes in DC current instead of data sent wirelessly. Just do it. Further, in the embodiment, if no operation is performed after a predetermined period of time has elapsed, the outside line acquisition state is set, but it may be set to the standby state.

[Effects of the Invention] As explained above, in this invention, after removing the cordless handset from the charger, it is possible to select whether to connect an extension line or an outside line. This eliminates the need to make an extension call from the phone, which has the effect of making operations easier.
