Abstract

PURPOSE:To make plural simultaneous services possible by providing two handsets, two telephone number pulse generating circuits, two telephone number reception detecting circuits, and one telephone number input operation part combinationally on one case of a telephone set. CONSTITUTION:Input signals from telephone lines (a) and (b) are detected by telephone number reception detecting circuits E1 and E2; and if the office of this telephone set itself is designated, speakers F1 and F2 are sounded, and services are possible when handsets D1 and D2 are hooked off. In case of telephoning, the number inputted from a telephone number input operation part A is converted to a dial pulse signal by number pulse generating circuits G1 and G2 and is sent to telephone lines (a) and (b), and service is possible when connection to the other party is completed. In this telephone set, one telephone number input operation part A, two handsets D1 and D2, two telephone number reception detecting circuits E1 and E2, and two telephone number reception detecting circuits E1 and B2, and two telephone number pulse generating circuits G1 and G2 are arranged on one case H.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set, and more particularly to a configuration in which a plurality of people can talk simultaneously using one telephone set.

〔overview〕

The present invention saves the installation space of a telephone by arranging one telephone number input operation section necessary for making a call, and two each of other circuits and handsets on one housing. This will reduce the size and simplify the facilities required for wiring.

[Conventional technology]

Conventionally, this type of telephone is equipped with a handset, a telephone number input operation section, a telephone number pulse generation circuit, and a telephone number reception detection circuit in one housing, and allows one subscriber to make a call. The structure inside was such that the phone was occupied.

[Problem that the invention seeks to solve]

Therefore, when a large number of telephones are installed in an office or the like, a large installation space is required, and installation costs are also high.

Furthermore, if the number of devices deployed is small, there are drawbacks such as having to wait until the call ends.

SUMMARY OF THE INVENTION An object of the present invention is to solve these drawbacks and to provide a telephone that requires less installation space and does not require high installation costs even when a large number of chargers are installed.

[Means for solving problems]

The telephone according to the present invention combines two handsets, two telephone number pulse generation circuits, two telephone number reception detection circuits, and one telephone number input operation section on one housing. , is characterized by the ability to make multiple calls at the same time.

In other words, in two telephones connected to two lines respectively, the hand center is provided separately, and some circuits including the dial operation part are provided in common, and the two telephones can be switched by operation. The two telephones are connected to each other, and the two telephones are mounted in one housing.

[Effect]

Since the time required to make a call on a telephone is short, even if one circuit for making a call, two other circuits, and two handsets are placed in one housing, they can be placed adjacent to each other. Do not worry about the inconvenience of operation for subscribers who are currently using the service.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of the above embodiment.

In FIG. 1, a telephone number input operation section A includes a number pad B having the same button arrangement as a general button telephone with numbers and symbols, and button switches C1 and C2 for switching the right to use handsets D1 and D2, The handset, receiver, and D2 are arranged on both sides of the telephone number input operation section A for ease of use.

FIG. 2 is a block diagram of the above embodiment.

Input signals from telephone lines a and b are detected by telephone number reception detection circuits E1 and F2, respectively, and if self-portrait is specified, speakers F1 and F2 are sounded, and a call can be made by lifting handsets D1 and D2. Become.

When making a call, the telephone number input from the telephone number manual operation section A is converted into a dial pulse signal by the telephone number pulse generation circuits G1 and G2, and sent to the telephone line. When the connection with the other party is completed, the call is completed. It becomes possible.

Here, the feature of the present invention is that one housing H has one
This arrangement consists of a set of telephone number input operation units A, two sets of handsets D1 and D2, telephone number reception detection circuits El and E2, and telephone number pulse generation circuits G5 and G2.

In this manner, by providing a plurality of handsets and receivers in the casing of one telephone, even when one person is using the telephone, another person can talk at the same time.

〔Effect of the invention〕

As explained above, according to the present invention, two people located next to each other can use one telephone at the same time, which has the effect of effectively utilizing space and reducing equipment costs by reducing the standard number of telephones deployed. .
