2. Description of the Related Art Conventionally, the number of business types in which a plurality of telephones are used in telephone shopping or the like to carry out a telephone reception business for shopping has been increasing. In this case, one operator operates one telephone. However, a ring tone sounds from a telephone other than the telephone operated by the user, and whether the ring tone is from the telephone operated by the user or whether another telephone is operating. It was very difficult to distinguish between ringtones and the operability was extremely poor.

In recent years, various telephones have been devised so that each telephone is surrounded by a soundproof wall or the like for each block so that the ring tone of the other telephone cannot be heard by the operator of the other telephone. In this way, it is possible to distinguish a ring tone from another telephone. However, if this method is used, when an incoming call is received when the operator leaves the seat, the other operator cannot hear the ring tone and cannot answer the telephone. That is, the business opportunity for the incoming call has been lost.

As another system, a method has been developed in which an operator manually blinks a light or the like when an operator leaves a seat to notify of an incoming call. However, this system has not been solved fundamentally due to forgetting the setting.

[0005] The above is a conventional example of the ringtone,
A conventional example of a hands-free call using a telephone is described below.

Conventionally, when making a hands-free call, the voice of the other party is output from a speaker, and the voice is usually used by an omni-directional speaker. The contents had been asked. As a solution, it is possible to change the above speaker to a directional speaker, but this time on the other hand, when people around you want to hear the sound from the speaker, you can not hear because the directional speaker is used Inconvenience occurs.

[0007]

In view of such problems, the present invention automatically determines whether or not an operator of a communication device is present by using an infrared sensor attached to the communication device and a weight sensor attached to a chair. When there is an operator, it is automatically set so that only the operator can hear the ring tone with a directional speaker, and when there is no operator, an operator operating another communication device with an omnidirectional speaker can be set. It is to provide a device that automatically sets to be heard. Also, if you do not want to hear the other party's voice around you during a hands-free call, output it with a directional speaker, and if you want people around you to output it, use an omnidirectional speaker. An object of the present invention is to provide a communication device that enables switching depending on the will of an operator.

[0008]

FIG. 2 is a flowchart showing the operation of the communication device according to the first embodiment. When the power switch 118 of the telephone is turned on, the telephone rises (S2) and shifts to a standby state (S3). Here, when an incoming call is received from the public network 101 (S4), the detection of the incoming call is transmitted from the incoming call detection unit 104 to the central processing unit 107. The central processing unit 107 checks the information on the presence or absence of the operator detected by the infrared sensor 109 (S5), and when it is determined that there is an operator, switches the changeover switch 113 to the directional speaker 115 side (S6). Here, the timer 111 is started (S
7), a ringtone is generated by the ringtone generator 112 (S
8) A ringtone is output to the directional speaker 115 via the changeover switch 113 (S10). Here, if a response is made, off-hook detection is performed by the hook detection unit 119, and a call is established on the route of the public network 101, the voice processing unit 103, the voice amplifier 105, and the handset 106 (S12).
At the end of the call, the on-hook is also detected by the hook detection unit 119, the direct current of the public network 101 is released by the local line interface 102, and the call is disconnected (S13).

When it is determined by the infrared sensor 109 that there is no operator (S5), the changeover switch 113 is switched to the omnidirectional speaker 114 side, and the ring tone generation unit 112 generates a ring tone (S16). Here, if an off-hook is detected by the hook detection unit 119, a call is established along the same route as above (S18), and the call is disconnected when the hook is on-hook (S19). If no off-hook is detected, the ringing tone continues to ring (S16).

When the ring tone is output from the directional speaker 115 and no off-hook is detected (S11), the switch 113 is turned on at the same time when the time-out of the activated timer 111 is detected. Switching to the speaker 114 (S14), a ringtone is output (S15).

This function is provided on the assumption that erroneous detection of the infrared sensor 109 or a case where a response cannot be made even if an operator is present.

The above sequence consists of the power switch 11
8 is repeated (S21). Since the above sequence is performed on the order of several millimeters, the output of the ring tone is delayed for the operator, and there is no sense of incompatibility.

(Second Embodiment) A second embodiment of the present invention will be described. FIG. 3 shows a flowchart of the operation. The configuration of the telephone is the same as that of FIG. Instead of S5 of the operation flow in the first embodiment shown in FIG.

In S23, if it is determined that the operator is seated based on the detection result of the weight sensor 116 attached to the chair on which the operator is seated, a ring tone is output from the directional speaker 115, and the operator is not seated. When it is determined that a ringtone is output from the omnidirectional speaker 114. As described in the first embodiment, the timer 111
If the weight sensor 116 malfunctions, if the operator cannot respond even when seated, or if something is placed on the chair, the omnidirectional speech force 115 is activated to output a ringtone.

(Third Embodiment) A third embodiment of the present invention will be described. FIG. 4 shows a flowchart of the operation. The configuration of the telephone is the same as that of FIG. In the flowchart of the operation of the second embodiment shown in FIG.
Up to this point, the description is omitted. In S4, an incoming call is received from the public network 101, and at this time, the directional speaker selection button of the operation unit 110 is pressed (S2
4) The changeover switch 113 is switched to the directional speaker 115 (S6), the ringtone is generated by the ringtone generator 112 (S8), and the ringtone is output from the directional speaker 115 (S10). Next, by depressing the hands-free hook button of the operation unit 110, the hook detection unit 119 detects an off-hook (S11), and then enters a hands-free call (S25). When releasing the directional speaker selection button of the operation unit 110 during a hands-free call and performing a hands-free call including surrounding traffic, the changeover switch 113 is switched to a non-directional speaker (S14), and the hands-free call is performed. Perform (S28). If the omnidirectional speaker is not switched, the hands-free call is continued (S27).
The above sequence is repeated until the power switch 118 is turned off (S21). The switching between the directional and omnidirectional speakers is performed in the order of several millimeters, so that the output of the hands-free call is not delayed or interrupted. Therefore, the operator does not feel uncomfortable at all.

[0019]

As described above, according to the first aspect of the present invention, the presence or absence of an operator is determined by an infrared sensor on the telephone, and the ring tone is automatically switched to a directional or omnidirectional speaker. Since there is no operator, there is no loss of business opportunity for incoming calls even when there is no operator.

According to the second aspect of the present invention, there is provided a weight sensor for a chair in which an operator operating a telephone is seated.
Judgment of the presence or absence of the operator, directing the ringtone automatically
Since the output is switched to the omnidirectional speaker, the business opportunity for the incoming call is not lost even if there is no operator.

According to the third aspect of the present invention, since the voice of the other party is switched to the directional and omni-directional speaker by the directivity and omni-directional speaker switching button of the operation unit of the telephone, and is output. This makes it possible to flexibly cope with cases in which a person does not want to be heard or a case in which a call is made with surrounding people.
