Abstract

PURPOSE:To automatically come to be a response mode and to execute the calling with a free hand literally by controlling a calling devige automatically in a responsable condition after a prescribed time when calling is executed in a calling system by a speaker and a microphone. CONSTITUTION:An incoming signal from a station is a signal which rings for one second and stops to ring for two seconds by 16 Hz as shown in Fig. (a), is detected by an incoming detecting circuit 4, the output as shown in Fig. (b), made into the output delayed through a delaying circuit 5 as shown in Fig. (c), for example, until after the incoming signal rings two times and inputted to an AND circuit 6. At such a time, since a setting switch SW1 is turned on, the output of the AND circuit 6 is inputted to an AND circuit 7 as shown in Fig. (d). Since a hand set 3 is on locked, the output as shown in Fig. (c) occurs, a relay circuit 8 is driven, a contact r1 is closed and a free hand network 1 comes to be a response mode. When the hand set 3 is picked up by a free person, a hook switch SW3 is closed, the output of the AND circuit 7 does not occur, and therefore, for the free hand network l, a response mode is released, and since a hook switch SW2 is closed at such a time, a usual calling can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION 1. Technical Field 1 The present invention relates to a telephone call system equipped with a hand-to-hand telephone communication device that uses a speaker and a microphone to make a telephone call without using a handset.

``Background Art'' Conventionally, this type of telephone call system includes a standalone telephone, an intercom, a key telephone device, etc. that can perform telephone calls to a central office, a doorbell telephone call, an extension telephone call, and the like. In such a telephone system, there is no hook switch that detects when the handset is lifted, unlike a VCR telephone equipped with a handset. To switch the V device from the standby state to the response ready state (hereinafter referred to as response mode), operate the push button switch, for example, press the push button.
It was necessary to perform operations such as pressing the switch with your foot. For this reason, the person being called may be unable to use their hands because they are working on some task, such as *A housewife in the garden is preparing meals and her hands are dirty and she is unable to press the button. In such a situation, the operation of this push button switch is very inconvenient. Moreover, although the main purpose of the telephone call system is to eliminate the need to use one's hands when making a call, having to operate this push button switch felt like a one-handed operation.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned points, and its purpose is to provide a telephone call system that automatically enters answering mode and allows hands-free telephone calls. be.

[1j11 of the Invention 1 (Structure) The present invention provides a telephone system for making telephone calls using a speaker and a microphone without using a handset; To disclose a telephone call system which is equipped with a control means for controlling to a response ready state, automatically enters a response mode, and allows telephone calls to be made literally hands-free.

(Example 1) FIG. 1 and FIG. 2 are diagrams showing an example of the present invention,
This embodiment relates to a call system used as a standalone telephone, and includes a hands-free call network 1 that allows hands-free calls using a speaker SP and a microphone MC;
This is a telephone system equipped with a handset communication network 2 that allows telephone calls using a normal handset 3. Further, as a control means for automatically controlling the above-mentioned hand 7 to the response mode after opening at a predetermined time when there is a call, the present embodiment includes an incoming call detection circuit 4, a delay circuit 5, and an AND circuit 6.7. , station #
10. a normally open contact r for connecting to the hands-free telephone network 1;
A mode in which the relay circuit 8 and the call system automatically enter response mode (hereinafter referred to as automatic response mode)
A set switch SW1 etc. is used to set the The incoming call detection circuit 4 detects an incoming call signal transmitted from the station, and the delay circuit 5 delays the output of the incoming call detection circuit 4 at a predetermined time and outputs the delayed signal. The AND circuit 6 generates an output when the set switch SWI is set, that is, turned on, and the delay circuit 5 output occurs, and the AND circuit 7 generates an output when the set switch SWI is set, that is, turned on, and the output of the delay circuit 5 occurs. When the hook switch SW is in an open state and the AND circuit 6 output occurs, an output is generated.

The relay circuit 8 is driven by the AND circuit 7 output input via the inverter 9, and when the AND circuit 7 output occurs, it closes the normally open contact RL and puts the hand 7 relay communication network 1 into response mode. It is something to do.

The operation of this embodiment will be explained below with reference to FIG. When the user is currently doing work that does not allow him to use his hands, such as preparing a meal, he turns on the set switch SWl to set the telephone system to automatic response mode. At this time, it is assumed that there is an incoming call and an incoming signal is transmitted from the station, as shown in FIG. 2(a). As shown in FIG. 2(a), this incoming call signal is a signal that rings at 16 Hz for one second and then stops ringing for two seconds. This incoming signal is detected by the yri reliability test high detection circuit 4 (Fig. 2 (1))
As shown in FIG. 2(c), the ff1(i detection circuit 4 output is generated. This output is output through the delay circuit 5, and is delayed until after the incoming signal rings twice, for example, as shown in FIG. 2(c). and is input to the AND circuit 6. At this time, the set switch SW is turned on, so as shown in FIG. 2(d), the output of the AND circuit 6 is input to the AND circuit 7. 3 is in an on-hook state, the AND circuit 7 is connected as shown in FIG. 2(e).
An output is generated and the relay circuit 8 is driven. Therefore, the normally open contact r is closed, and the hand 7 and the communication network 1 are controlled to be in the response mode. Also, when a call arrives, if the call system is set to automatic answering mode and someone is free, this person can use the handset call network.
If you pick up the handset 3 (r), the hook switch S
Since W is closed and the AND circuit 7 output is not produced, the hands-free telephone network 1 is released from the response mode, and at this time the hook switch SW2 is closed, so that a telephone call can be made using the normal handset 3. As described above, according to the present embodiment, the set switch SW is turned on before the hand becomes unusable. Fhrj; By setting answer mode 1, it is possible to automatically control hand 71J-telephone network 1 to answer mode, eliminating the need to operate a push button switch during a call as in the past. You can now make calls.

(Embodiment 2) Figures 3 and 4 are diagrams showing other embodiments of the present invention, and this embodiment is a key telephone device that can make telephone calls to a central office, doorbell calls, extension calls, etc. This is an application of the invention. This call system is a base unit.

0 and a plurality of slave units 11, a hand 7 remote control device A capable of making handset calls, and a door phone 12 are also provided as slave units. This base unit 10 is station #X0. The slave unit 11 is connected to the base unit 10 via an extension line. The aiso 10 and the hand 717-communication device A are 4- to 8-core 4W wires such as data transmission lines and communication lines.
It is connected by an extension line consisting of 'f wire. Figure @4 is a diagram showing the configuration of the hand 71 communication device rftA, which includes the data transmitting/receiving section 13 that receives data indicating the incoming call that is transmitted from group 10 when there is an incoming call, and the data transmitting/receiving section ffl 513 that receives the incoming call.

(Embodiment 3) FIG. 5 and FIG. 6 are diagrams showing still other embodiments of the present invention. Although it was necessary to set the value beforehand, this embodiment has improved this point. In other words, the set switch SW automatically detects that the user cannot take his hand off.

This eliminates the need for this operation. First, the method shown in FIG. 5 will be explained. The configuration of the device except for the set switch SW1 is the same as the configuration of the fjSl or f52 embodiment. In the case of Fig. 5, this was done in consideration of the fact that when the user is standing in the kitchen, especially in front of the 111 Rishin 216, the user is often unable to take his or her hands off. Specifically, a sensor S such as a piezoelectric element that detects when a person stands on the floor mat 15,
It uses In operation 'C, when a person stands on the floor mat 15, the above-mentioned set switch SW1 is turned on, that is, the automatic response mode is set, and the person gets off the floor mat 15. Then, the automatic answering mode is canceled and the phone enters the normal handset call mode. In addition, hand 717 - telephone equipment f! IA is +
It is installed in M17. Next, the method shown in FIG. 6 will be explained. The case shown in FIG. 6 uses a proximity detection sensor S2 that detects a human body using ultrasonic waves or the like, and can perform substantially the same operation as the floor mat 15 described above.

In addition to the method described above, if a device capable of detecting a human body entering a predetermined place is used instead of the set switch SW,
Needless to say, it is possible to cause a similar behavior. As described above, according to this embodiment, there is no need to switch between devices, and it is possible to literally make a phone call.

[Effect of the Invention 1] As described above, the present invention is equipped with a control means that automatically controls the hand 7 recovery device to a ready state after a predetermined period of time when there is a call, so that if there is an incoming call 8. If you are performing a task that does not allow you to use your hands like in the past, you can temporarily stop the task and switch to a ready state by operating a push button switch. This eliminates this problem, making it easier for the user to use the device, and thus making it possible to literally make hands-free calls.
