Abstract

PURPOSE:To reduce the collision of incoming and outgoing by conducting a preparatory incoming processing at first when the incoming from a main wire is detected to disable the outgoing and conduct the incoming display by means of a display element. CONSTITUTION:When the incoming signal comes to a main wire 8, it is detected by an incoming detection section 1 and inputted to a microcomputer 10. If it is decided that a signal from the detecting means 1 is not consecutive for a prescribed time (250ms) or over, the microcomputer 10 drives a control means 3 to inhibit the outgoing and also light a display element such as a light emitting diode by an incoming display means 5. If the next incoming signal does not reach successively, the end of call processing is conducted and if the incoming signal comes successively, the incoming processing is conducted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention drives a separately provided incoming signal generator based on the received incoming signal from a central office line, and uses the output of this incoming signal generator to generate an incoming call from the local office. The present invention relates to a telephone device, such as a so-called button telephone device, which is configured to notify that there is an incoming call from a line by a ringtone or a display element such as a light emitting diode.

Conventional configuration and problems Generally, when a key telephone device receives an incoming call signal from a central office line, it drives a separately provided incoming signal generator based on the received signal, and the output of this incoming signal generator is used to generate a call from the central office line. Many are configured to notify you of an incoming call. By the way, in all conventional telephone devices of this type, the incoming signal generator from the central office line is driven by noise from the central office line, and in order to prevent erroneous operation, the incoming signal from the central office line is predetermined. The device is configured so that the incoming call signal generator is not activated unless it is present for a relatively long period of time (e.g. 250 m5), so if you pick up the handset and try to make a call without a ring tone or an incoming call display, Even if you do, you may still receive a call from the other party, and you may hear the other party's voice on the handset, which is often very unpleasant.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide an excellent telephone device that has a simple configuration and can reduce collisions between incoming and outgoing calls.

Structure of the Invention The present invention comprises: a detection means for detecting an incoming signal from a central office line; a means for determining whether the duration of the incoming signal detected by the detection means is longer than a predetermined certain time; When the determination means determines that the duration of the incoming call signal is longer than a predetermined period of time, the ring tone sending means provided separately is controlled to be driven, When it is determined that there is an incoming call signal, the incoming call display means that does not drive a separately provided light emitting diode or other display element is driven, and the ring tone sending means is driven only when the next incoming call signal arrives successively. It is equipped with a control means for controlling.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a block diagram showing the configuration of an embodiment of the telephone device of the present invention. In FIG. 1, 1 is an incoming call detection means for detecting an incoming signal from a central office line, and 2 is an incoming call detection circuit 1.
A determining means for determining whether the duration of the incoming call signal detected by the incoming call signal is longer than a predetermined fixed time; This control means drives and controls the incoming call display means 5 which drives the light emitting diodes and other display elements.

FIG. 2 is a block diagram showing a specific configuration of the above embodiment, and in the figure, the same reference numerals as in FIG. 1 indicate the same components as in FIG. 1. Reference numeral 7 denotes a ring tone generation means, which is connected to the link switch section 61 by the ring tone transmission means 5.
It consists of 8 is a central office line, and 9 is a telephone set, each of which is connected in plural numbers. Reference numeral 10 denotes a microcomputer constituting the incoming call determination means 2, which is configured to determine incoming calls using a built-in program and to control the control unit 3 based on the respective determination results.

The microconbeater 10 includes an input section 10a that receives the output of the incoming call detection means l, a storage section 10b that stores the incoming call mode, and an output section 10d that outputs control signals to the control section 3 according to the incoming call modes. , a storage section lOb, an input section 10a, and an output section 10d, and includes an arithmetic control section 10C that performs data comparison operations and the like.

In the above embodiment, when an incoming signal arrives at the office line 8,
This is detected by the incoming call detection means 1 and inputted to the microconbeater 10 constituting the determination means 2. When the microcon beater 10 receives an output from the incoming call detection means 1, it first determines in step 21 whether or not this is an incoming signal, as shown in FIG. If the output from the incoming call detection means 1 is an incoming call signal, step 2
2, it is determined whether the duration of the incoming signal is longer than a predetermined first constant time (for example, 150 m5). If it is determined that the incoming call signal from the incoming call detection means l continues for a predetermined first certain period of time (150 ms) or longer, the process moves to step 23, where the incoming call signal is further detected in a predetermined manner. It is determined whether or not it continues for a second certain period of time (for example, 250 m5) or more. If it is determined in step 23 that the incoming call signal from the incoming call detection means 1 continues for more than the second fixed time (250 ms), the control means 3 controls the link switch section 6, and the incoming signal from the incoming call detection means 7 is activated. A control signal for causing the telephone set 9 to send out a ringtone symbol is output. Therefore, in this case, in step 24, incoming call processing is performed and the ringing tone signal from the ringing tone generating means 7 is sent to the telephone set 9 via the link switch section 6, so that the telephone set 9 outputs the ringing tone. In this case, the microcomputer 10 simultaneously outputs a signal to the control means 3 to drive the incoming call display means 5. Therefore, at the same time in step 24, the incoming call display means 5 is driven, and a light emitting diode and other display elements (not shown) are turned on. However, in this case, the fact that there is an incoming call from the central office line is reported by both the ringing tone from the ringing tone generation means 7 and the display by the display element.

If it is determined in step 23 that the incoming signal from the incoming call detecting means 1 has not continued for more than the second fixed time (250 ms), the process moves to step 25, where a preliminary incoming call process is performed. In other words, in this case, the microcomputer 1o outputs a control signal to the control means 3 to drive the incoming call display means 5, and at the same time outputs a signal to prohibit the outgoing call. Therefore, the control means 3 operates to prohibit outgoing calls, and the incoming call display means 5 lights up the light emitting diode and other display elements.

This state is then temporarily stored in the memory section Ob, and in the next step 26 it is determined whether the next incoming signal has arrived. If the next incoming signal does not arrive subsequently, the process moves to step 28, where call termination processing is performed, and all processing performed in steps 25 and 26 is restored to its original state. When the next incoming signal arrives successively, the process moves to step 27, where the incoming call processing is performed in the same manner as in step 24. Therefore, when the incoming signal from the incoming call detecting means 1 is within the second fixed time, complete incoming processing is performed for the first time in step 27, and at this point the incoming signal from the incoming tone generating means 7 is detected by the telephone 9. You will be notified in due course.

In this way, according to the above embodiment, even if the incoming signal from the central office line does not continue for a predetermined period of time (second), when this is detected, preliminary incoming processing is first performed in step 25, and the call is made. In addition, since the incoming call is displayed using a light emitting diode or other display element, it is possible to prevent the user from accidentally lifting the handset in an attempt to make a call when receiving a call, and this greatly reduces collisions between incoming and outgoing calls. It has the advantage of being able to

Effects of the Invention As is clear from the above embodiments, the present invention determines the duration of an incoming call signal, and if the duration is longer than a predetermined certain time, immediately processes the incoming call and stops the ring tone generation means. The incoming call signal is transmitted to the telephone and a ring tone is emitted.If the duration is less than the predetermined time, the incoming call processing is not immediately started, but the incoming call is indicated by a light emitting diode or other display element first. The device is configured so that the incoming call process described above is performed only when the next incoming signal arrives, and even if the incoming signal does not continue for a predetermined period of time, the light emitting diode or other display is first activated. Since the incoming call is displayed by the device, it is possible to prevent the handset from being lifted up to make a call even though there is an incoming call by mistake, and it is possible to prevent the phone from lifting up the handset to make a call when there is an incoming call by mistake. If it is within the time limit, the ring tone will not sound until the next incoming signal, so it can easily prevent the ring tone from being played due to noise or other factors, which is extremely advantageous in practical terms. It is something.
