Abstract

PURPOSE:To reduce noise and power consumption by calling a busy set of a room of the next priority on the condition that the busy slave set in a room of the higher priority does not respond to the call within a predetermined calling period so as to allow a proper party of each room staying therein. CONSTITUTION:A main telephone circuit is provided with an exchange circuit section 3 applying exchange connection to a trunk line and each busy slave set, a control circuit 16 decides the call priority of each loop at the incoming call from the trunk line or other slave set and starts the calling from the slave set of a room with the higher calling priority at the incoming call from the trunk line and also starts the calling of the slave set of a room of a 2nd calling priority on the condition that the slave set with the highest calling priority does not respond to the call within a predetermined period. Thus, a proper person in each room staying therein can respond to the call in the event of the incoming call from the trunk line or a doorphone so as to reduce the noise and power consumption attended with the incoming call.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to telephone devices.

[Prior art] A telephone device such as a home telephone is constructed by installing a plurality of handsets such as telephones and intercoms in each room in the house, such as a housekeeping room, a reception room, a study, a bedroom, and a children's study room. There is something.

In the above-mentioned telephone device, all in-house telephone handsets ring in response to an incoming outside line call from the central office line, and an outside line call can be established with the off-hook handset.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional telephone device, when an outside call is received from one central office line, all the telephone handsets ring simultaneously.

For this reason, for example, even if a housewife in the housekeeping room plays the role of a telephone operator, when an outside call rings all at once, people in other rooms will not be able to tell whether there is a housewife in the housekeeping room or not. , a person living in another room may answer the call by going off-hook with the handset in his or her own room. This creates a situation in which the people at home in other rooms are unnecessarily interrupted from entertainment, reading, sleeping, studying, etc. that they had been doing up until the time the outside call arrived.

In addition, if a business office with a high call level is located in a multi-family residence, those who are at home in a room other than the office will have to call the telephone number in their own room in response to the simultaneous ringing of incoming outside calls. If the machine goes off-hook, it is often necessary to transfer the caller on an outside line to a sales person in the office. For this reason, there is a risk that a prompt response for sales may be lacking.

In addition, ringing can cause noise and disturb sleep,
There is also the disadvantage that it involves wasteful power consumption.

The present invention enables incoming calls from outside the home, from a central office line, doorbell, etc.
Among the people in each room, the most appropriate person will respond,
The purpose is to reduce noise and power consumption associated with calls as much as possible.

[Means for Solving the Problems] The present invention provides a main telephone circuit connected to a central office line, a plurality of telephone handsets installed in each room of a house and connected to the main telephone circuit, A telephone device comprising a control circuit for driving and controlling a main telephone circuit, wherein the main telephone circuit is equipped with a switching circuit section that can perform exchange connection between a central office line and each handset, and the control circuit is a central telephone circuit. Alternatively, set the ringing priority for each room when receiving a call from another handset, and when an external call is received from the central office line, the ringing operation is started from the handset in the room with the higher calling priority, and the priority of the first call is set. The calling operation of the calling handset in the next room in the calling order is started on the condition that the handset in the room does not respond within a predetermined calling operation period.

[Function] According to the present invention, when a call signal is received from a central office line, a doorbell, etc., the control circuit does not ring all handsets in all rooms at once, but first calls the room with the highest call priority. A calling operation is performed on the handset, and when there is no response within a certain calling operation period, the calling operation is performed on the next calling handset in the calling order. Therefore, it is possible to respond to the call by the most appropriate person among those staying in each room, and to reduce the noise and power consumption associated with the call as much as possible.
