Abstract

PURPOSE:To offer absence transfer services only when a user is absent and to insure said services against being transferred when the user is present irrespective of whether or not the transfer service is set by detecting the absence of the user of a key telephone system by a sensor part installed in the key telephone set. CONSTITUTION:The key telephone system 1 is provided with a sensor part 2 and a processing part 3. The transmitting part of the sensor 2 transmits light or ultrasonic waves, and a receiving part detects the existence or absence of the reflection to know the absence. A main equipment 4 is provided with a CPU 5, a memory device MEM 6 and an interface part INF 7. When the sensor part 2 detects the absence of the user of the key telephone system 1, the processing part 3 processes the signal from the receiving part of the sensor 2 and transmits an absence signal. When the absence signal is transmitted to the CPU 5 through the INF 7, the CPU 5 reads information on an absence transfer destination and executes an absence transfer service program. Consequently, all the calls incoming to the key telephone system 1 while the user is absent are transferred to the transfer destination. When the call is received in the user's presence, the CPU 5 recognizes the user's presence and executes the incoming call process to the key telephone system 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a button telephone device, and more particularly to a button telephone device in which a sensor detects the absence of a user of the key telephone and provides a call forwarding service.

[Conventional technology]

Conventionally, the call forwarding service of key telephone devices uses the central processing unit (hereinafter referred to as CPU) of the key telephone to set or cancel the call forwarding destination by operating several buttons on the key telephone. Incoming calls to the set key phone were always forwarded regardless of whether the user was present or not.

[Problem that the invention seeks to solve]

In the conventional key telephone device described above, the call forwarding service is set by operating several buttons on the key telephone, but without this setting, the user of the key telephone was away from his/her seat and was absent. In some cases, the call is not forwarded, and the caller has to make several consecutive calls because the caller cannot immediately know whether the other party is unavailable or not. Another drawback is that if the call forwarding service is set while the user of the key telephone is present, incoming calls to the key telephone will always be forwarded to the call forwarding destination.

Means for Solving Problem C] The button telephone device of the present invention includes a button telephone and a main F device, and the button telephone has a sensor section for detecting the presence or absence of the user, and a sensor section for detecting the presence or absence of the user. and a processing unit that transmits a detection signal to the main device, and the main device includes a central processing unit, a storage device that stores information regarding the call forwarding service, and an interface unit that interfaces with the key telephone.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the button telephone device of the present invention.

In the figure, the button telephone device consists of a button telephone 1 and a main device 4. The button telephone 1 includes a sensor section 2 and a processing section 3. The transmitting section of the sensor section 2 sends out light or ultrasonic waves, and when the user of the button telephone 1 is present, there is a reflection of the light. Since there is no reflection when the person leaves the seat and is absent, it is possible to know whether the person is present or absent by detecting the presence or absence of this reflection at the receiver. Also, the main device 4 is a CP
U5, a storage device (hereinafter referred to as MEM) 6, and an interface unit (hereinafter referred to as INF) 7 that interfaces with the processing unit 3, and the MEM 6 stores information on a call forwarding destination, a call forwarding service program, a called party absence display program, etc. is stored.

Next, the operation of this embodiment will be explained.

When the sensor section 2 detects the absence of the user of the button telephone 1, the processing section 3 processes the signal from the receiving section of the sensor section 2 and sends an absence signal to the INF 7.
7 to the CPU 5, the CPU 5
The call forwarding destination information stored in step 6 is read out and the call forwarding service program is executed. Therefore, all calls that arrive at the key telephone 1 for which the call forwarding service has been set by the user when the user is not present are forwarded to the forwarding destination. Note that when the call forwarding service is set and a call arrives at the button telephone 1 while the user is present, the processing section 3 processes the signal from the sensor section 2 and converts the presence signal to the INF7.
Since the CPU 5 recognizes the presence of the user and does not read the information from the MEM 6, the CPU 5 performs generally known incoming call processing to the button telephone 1. Therefore, the user can respond to this incoming call.

In addition, if the user receives a call to key telephone 1 for which the call forwarding service has not been set up while the user is not present, CPLJ
5 executes the called party absence program based on the absence signal from the processing unit 3 and the information that there is no call forwarding destination read from the MEM 6. In other words, the process involves sending a sound or message to the caller to inform the caller that the called party is absent, so that the caller knows that the called party is absent from the audible or visible display. I can do it.

〔Effect of the invention〕

As explained above, the present invention detects the absence of the key telephone user using the sensor unit provided in the key telephone, so that incoming calls will not be forwarded even if the user leaves the telephone without setting the call forwarding service. The caller will not be left waiting, and if the call forwarding service is set up and the user is present, the incoming call will not be forwarded to the call forwarding service. Regardless of whether the user is present or not, call forwarding service is performed only when the user is absent, and call forwarding is not performed while the user is present.
