Abstract

PURPOSE:To facilitate the operation at dialing in various telephone sets remarkably by setting a reception loudspeaker mode when a speech line is acquired and selecting the mode into the handset speech mode with a detection output so as to attain the automatic changeover of the speech mode. CONSTITUTION:When off-hook operation of a slave set S is detected and an external line key is depressed, a CPU 36 detects it and allows a radio transmission reception section 31 to send a dial signal to a master set M. A CPU 9 of the master set M receiving the dial signal through a radio transmission reception section 17 turns on a transistor(TR) 2 via a dial IC 8 to acquire an external line L and to set a speech channel between the master set M and the slave set S and sends speech start data to the slave set. The CPU 36 of the slave set S receives the data to activate an amplifier 41 and sends a dial tone from the external line L to a speaker 39. When the dial key is operated, the CPU 36 of the slave set S sends the dial signal to the master set M to attain the handset speech mode.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone apparatus provided with a handset call mode in which a call is made by a handset using a call line, and a reception call communication mode in which a voice signal on the call line is received and spoken by a built-in speaker.

[0002]

2. Description of the Related Art Generally, in a telephone device of this type, when making an outgoing call, a device without a built-in speaker must
After taking an outside line by going off-hook, the dial tone of the outside line is confirmed by a receiver, and then a dial operation is performed. In the case of a telephone device with a built-in speaker, after capturing an outside line, the device is manually switched to the speaker reception to check the dial tone and perform a dial operation. When the other party answers, the device is manually switched to the receiver again.

[0003]

If the above-mentioned conventional telephone device does not have a built-in speaker, it is necessary to confirm the outside dial tone while putting the receiver on each ear before dialing. For this reason, in offices and the like that perform rapid business processing by making full use of telephones, telephone apparatuses with built-in speakers have become mainstream in recent years. The telephone apparatus that enables such speaker reception is convenient because the outside line dial tone can be heard from the speaker, but the operation is troublesome because switching to the speaker side or the receiver side is manually performed. There was a problem.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of a telephone device according to the present invention, which is a wireless telephone device including a master unit M and a slave unit S. In the figure, a master unit M includes a communication circuit 3,
An incoming call detection circuit 7 for detecting an incoming call arriving at the outside line L, a loop of the outside line L is turned on by turning on the transistor 2, and a dial IC 8 for sending a dial signal to the outside line L, a CPU 9, a PB signal arriving at the outside line L Receiver 10, a line signal detecting unit 11 for detecting a call-call signal (click signal) arriving on the outside line L during a call, an ID / ROM 12, a function key 1.
3, a dial key 14, a speaker 15, an amplifier 16, a wireless transmission / reception unit 17 for performing wireless communication with the slave unit S, and the like.

[0007] Further, the handset S includes a radio transmitting / receiving unit 31, a handset (R) 34, and a handset (T) 3 for performing radio communication with the master unit M.
5, a function key including a CPU 36, an outside key, an off key used to end an outside call, a dial key,
The key unit 37 includes a speaker key and a flash key, a tone ringer 38 for transmitting a ring tone, a speaker 39, an ID / ROM 40, an amplifier 41, and the like.

As shown in the operation sequence diagram of FIG. 2, when an off-hook operation of the slave unit S is detected and an outside line key is pressed, the CPU 36 detects this and sends a transmission signal to the master unit M via the wireless transmission / reception unit 31. Send as The CPU 9 of the master unit M that has received the transmission signal via the wireless transmission / reception unit 17
The external line L is captured by turning on the transistor 2 via the dial IC 8, a communication channel between the master unit M and the slave unit S is set, and call start data is transmitted to the slave unit S. The CPU 36 of the slave unit S turns on the amplifier 41 in response to the reception of the call start data, sets the reception voice communication mode, and emits the dial tone coming from the outside line L to the speaker 39. When the dial key of the slave unit S is operated in the receiving voice communication mode, the C of the slave unit S
The PU 36 transmits dial data to the base unit S to transmit a dial signal, and further turns off the amplifier 41 to set the receiving voice communication mode to the handset communication mode. In this way, the dial signal is sent to the outside line L to call the other party, and a mutual call by the handset is started in response to the other party's response.

FIG. 4 and FIG. 5 are flow charts showing the operation of the first embodiment for automatically switching between such a handset call and receiving and talking voice call. FIG. 4 is a flow chart of the CPU 9 in the master unit M. FIG. 5 shows the CPU 3 in the slave unit S.
6 is a flowchart of FIG. First, the operation of the CPU 9 shown in FIG. After power-on and reset release, an initialization signal is executed (step 100), and subsequently, in step 101, it is determined whether there is data received from the slave unit S. If there is received data, it is determined in step 102 whether the received data is an outside line capture request by operating an outside line key. If the received data is an outside line capture request, the outside line is captured (step 103). On the other hand, call start data is returned (step 104). As a result, a dial tone arrives from an exchange (not shown) to the outside line L, and the dial tone reaches the amplifier 41 in the slave unit S. If it is determined that the received data is not an outside line capture request, the process proceeds to step 105 to determine whether the request is a dial transmission request by operating a dial key, and the request from the slave unit S is determined to be a dial transmission request. If so, the dial IC 8 is driven to transmit a dial signal to the outside line L (step 106).

[0010] In response to the above operation of the master unit M, the slave unit S operates as shown in the flowchart of FIG. That is, in step 150, it is determined whether there is data received from master unit M. If there is received data, it is determined in step 151 whether or not the received data is call start data. If the received data is call start data, the outside line capture state is stored (step 15).
2) Do it. Then, in step 153, it is determined whether or not the state of the external line before the arrival of the call start data is an incoming state. If the state is an incoming state, the amplifier 41 is turned off and the dial tone speaker 39 from the external line L is turned off. In step 154, a handset call mode is set to prevent release to the user.
If it is not in the incoming call state, it means that the outside line is to be captured for outgoing call, so that the amplifier 41 is turned on to set the receiving voice communication mode in which the dial tone from the outside line L is emitted to the speaker 39 (step 155). Subsequently, at step 157,
The key input by the operation of the key unit 37 is determined, and when the key input is detected, the key data is transmitted to the master unit M (step 158). Then, it is determined that the pressed key is the first digit of the dial (step 159), and the state of capturing the outside line in step 160 is determined. If there is, then the receiving voice communication mode is determined (step 16).
1). In this case, the amplifier 4 is used in the receiving voice communication mode.
1 is set to the handset communication mode to turn off (step 162), and other processing of step 163 is performed, and then the processing returns to step 150. As described above, when the external line key is pressed, the external line key data is transmitted to the base unit,
The receiving and loudspeaker mode is set based on the call start data returned from the master unit M by transmitting this data, and the handset talking mode is set when the dial key is further pressed.

FIG. 6 is a flowchart showing the operation of the second embodiment, showing the operation of the slave unit S. In this flowchart, the operations shown in steps 200 to 208 are the same as the operations shown in steps 150 to 158 in FIG. That is, if the data received from the base unit S is the call start data, and if there is no incoming call before the arrival of the communication start data, the mode is set to the receiving voice communication mode, and the presence or absence of a key input is determined in step 207. If there is a key input, the key data is transmitted (step 208), and it is determined in step 209 whether the input key is an outside line key. In this case, if the outside line key is input, the storage of the outside line capture state is checked in step 210, and if there is no storage, the outside line key is pressed to newly capture the outside line. 2
At 11, a timer for a fixed time is started. That is, the outside line key data based on the input of the outside line key is transmitted to the master unit M in step 208, and as a result, the master unit M
In step 205, the call receiving loudspeaker mode is set by the call start data returned from. In this way, the timer starts simultaneously with the pressing of the outside line key, and when a certain time elapses and the time is up, the determination in step 213 becomes “Y”, and in this case, it is determined whether or not the current reception and loudspeaker mode is set. At the same time (step 214), in the case of the reception voice communication mode, the amplifier 41 is turned off and the mode is shifted to the handset communication mode in which the signal from the outside line L is switched to the receiver 34 side (step 21).
5). When the external line key is depressed in this way, the timer is started, and after receiving the external line key data, the call receiving data returned from the master unit M is used to set the receiving voice amplification mode. The mode is shifted to the mode.

FIGS. 7 to 9 are flowcharts showing the operation of the third embodiment, and show the operations of the master unit M and the slave unit S when responding to a call waiting call from a third party during a call. Things. 7 and 9 are flowcharts showing the operation of the slave unit S, and the flowchart of FIG.
5 shows the operation of the parent device M corresponding to the operation of the child device S shown in FIG. First, a description will be given from the flowchart of FIG. The operations shown in steps 250 to 257 in FIG. 7 are the same as the operations shown in steps 150 to 157 in FIG. That is, master unit S
If the data received from is a call start data, the reception voice communication mode is set. At step 257, the presence or absence of a key input is determined. If there is a key input, key data is transmitted (step 258), and it is determined at step 259 whether the input key is an operation of a flash key for answering a call waiting call. To judge. In this case, if the operation of the flash key, that is, the hooking operation is performed, the determination in step 259 becomes “Y”, and
If the "memory of outside line capture state" of "0" is "Y", the "received voice communication mode" of step 261 is confirmed, and the handset communication mode is set in step 262. In this way, a call waiting signal arrives during an external call,
At this time, when the flash key of the slave unit S is operated, the handset communication mode is set.

Next, a flow chart showing the operation of the master unit S in FIG. 8 will be described. After the initialization processing in step 300, a call is made to the other party by operating the outside line key and the dial key of the slave unit S, and after the other party answers, a call state is established (handset talking mode). When a call ringing signal arrives from the third party via the outside line L during a call with the other party, the CPU 9 detects the call ringing signal via the line signal detecting unit 11 and proceeds to step 301 "Detection of click signal based on call ringing signal". Is "Y". In this case, after judging “external line communication state” in step 302 and “whether or not to subscribe to the call waiting service” in step 303, if both of them are determined to be “Y”, a click signal detection flag is set (step 304). ). In this case, the call waiting signal is heard on the slave unit S via the outside line L, and when the flash key of the slave unit S is operated to respond to the call, a “received data exists” in step 306 and a step 308 in FIG. "Flash key data"
Are both "Y", the external call state is confirmed in step 309, and it is determined in step 310 whether the click signal detection flag is set. If this flag is set, the child The handset communication mode is instructed to the machine S (step 311). If the click signal detection flag is not set,
Since the connection of the outside line L has been changed in order to make a call to another party, the receiving voice communication mode is instructed (step 3).
12). As a condition for setting the click signal detection flag, the click signal detection flag may be set only by detecting the click signal, or may be set only by the condition that the call waiting service is subscribed.

In this way, an outside-line call and a call waiting response are performed, and when these calls are ended, the off key, which is one of the function keys in the slave unit S, is pressed. In this case, the determination of the reception of the "off key data" in step 313 is "Y", and after confirming the "external line communication state" in step 314, the "external line release" in step 315 is performed.
Processing and resetting of click signal detection flag in step 316 ". When the slave unit S presses the outside line key, the "outside line key data" in step 307 becomes "Y" in the master unit M. In this case, "N" in "outside line communication" in step 320 is confirmed. Then, it is determined at step 321 that "outside incoming call is being received". If the outside line is not being received at this time, the outside line is newly acquired (step 322), and the outside line is acquired (step 322).
23). Thereafter, a series of processes such as the above-described call of the other party, the call by the answer of the other party, and the answering of the call waiting are performed. If the external line is receiving a call when the external line key data is received, an external line is captured (step 324) and a handset call mode is instructed to the slave unit S (step 32) in order to immediately start a call in response to the incoming call.
Perform 5).

The operation of the slave unit S corresponding to the operation of the master unit M is as shown in the flowchart of FIG. Here, the operations in steps 350 to 355 are almost the same as the operations in steps 157 to 163 in FIG. That is, if there is a key input after capturing the outside line L, the key data is transmitted to the master unit M (step 351), and the input key data is a dial key, which is the first digit dial after the outside line is captured. If there is any ("Y" in step 352), if the receiving voice communication mode is set, the mode is set to the handset communication mode (step 354).
After that, the dial key is pressed and the call is sent to the other party,
When the other party answers, the call enters a call state. When a call is received from a third party in such a call state and the call is heard through the handset 34, the flash key is operated to respond to the call. In this case, step 350 is performed. Is “Y”, the flash key data is transmitted to the master unit M in step 351. As a result, as described in detail in the flowchart of FIG. 8, the handset communication mode instruction data is returned from the master unit M, so that “received data present” in step 356 and “handset communication mode instruction data” in step 357 are both included. A determination of "Y" is made, and a handset call mode is set in step 358, and a call with a third party is made via the handset. In this way, when a call is answered during an outside line call, the mode is shifted to the handset call mode. If the flash key is pressed and the key data is transmitted to master unit M before the call waiting signal arrives, master unit M determines that the connection of outside line L has been changed, and is therefore returned from master unit M. The data is reception voice communication mode instruction data. As a result, in step 360 after "Y" in step 359, the receiving and talking voice communication mode is set.

In the present embodiment, the switching timing of the call mode when shifting to the call state by the other party's response is determined by processing on the slave unit S side, such as the determination of the first digit of the dial and the determination of the timer time-up. I try to do it,
The switching may be performed by a control signal from the master unit M. In the present embodiment, the speaker 3 on the slave unit S side
9, the speaker 15 of the master unit M side receives and raises the reception voice. At the same time, the master unit M returns a control signal based on the dial data transmitted from the slave unit S, and the handset talks with the slave unit. May be switched to.
In this case, in the flowchart of the master unit M shown in FIG. 4, “external line capture” in step 103 is “external line capture in the base unit reception loudspeaker mode”, and “child device” is before or after “dial transmission” in step 106. Step "Output handset call start signal to". As a result, the slave S
"Handset call" by receiving this call start signal
Becomes Further, in the present embodiment, an example in which the present invention is applied to a wireless telephone device is described. However, the present invention is also applicable to a general telephone such as a single telephone, an answering machine and a key telephone device. it can. The operation method and operation state in this case are as shown in FIG.
