Abstract

PROBLEM TO BE SOLVED: To provide a public telephone set system, satisfactorily maintaining the sanitary state of the transmitter/receiver of a public telephone set at the time of using the public telephone set. SOLUTION: This public telephone set system is provided with plural transmitters/ receivers, which can be physically and electrically connected to and separated from a telephone set main body, the telephone set main body in a system enabling speech by being connected to and separated from one of the transmitter/receiver, and a charging system for executing charging according to the connection and separation. When a transmitter/receiver side connector 11 of the transmitter/receiver 1 constituted of a microphone 13, a speaker 14, and a memory 12 is physically and electrically connected with a main body side connector 21 of the public telephone set main body 2, the classification and charging system of the transmitter/receiver 1 is identified, and an off-hook state is obtained, and when a telephone number or the like is inputted by a push type dial 26, mutual speech can be realized, and the charging system can be started. After the end of the mutual speech, by having the transmitter/receiver side connector 11 separated so, the execution of the charging system can be ended, and simultaneously an on-hook state can be obtained.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a public telephone system and a telephone handset of a public telephone, and more particularly to a telephone handset capable of ensuring good hygiene.

[0002]

2. Description of the Related Art Conventionally, a public telephone system comprising a handset, a telephone body, and a billing system, which are always connected, is used by an unspecified number of people, and may be installed outdoors. Because of the large number, it has been difficult to maintain good hygiene in the transmission and reception part.
In addition, public telephones installed in hospitals, etc., are likely to be a route of disease transmission because the receiving part of the handset may directly contact the lips of the user. I was having.

[0003] However, in order to maintain good hygiene of the transmitting and receiving part, a method of periodically cleaning and disinfecting the part or a method of covering the part with a disposable protective cover or the like is only taken, and it is fundamental. Techniques for improving technology were difficult.

[0004]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a public telephone system which can maintain good hygiene of a handset of a public telephone.

[0005]

In order to solve the above-mentioned problems, in a public telephone system according to the present invention, a connector which allows a user himself to easily physically and electrically couple and disconnect the public telephone main body and a handset is provided. By making it part, one handset can be used with multiple handsets.
Further, by incorporating a memory capable of executing a charging system such as a prepaid system into the handset of the present invention, the charging system can be executed by coupling and separating the handset.

Further, as a handset of the public telephone system of the present invention, a microphone and a speaker of a communication device such as a mobile phone can be used.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an electric circuit block diagram of a public telephone system of the present invention, and FIG. 2 is a perspective view showing an embodiment of the public telephone system of the present invention.

As shown in FIG. 1, the handset 1 of the present invention comprises a microphone 13, a speaker 14, and an electrical circuit of a memory 12 having information such as a model identification, a billing system, or a telephone number for automatic dial input. A cord 25 extends from the handset 1 and a handset-side connector 11 is attached to the end thereof.

As shown in FIG. 1, the public telephone body 2 of the present invention includes, in addition to a main circuit section 24, an identification section 22 for identifying the type of a handset of the present invention, and a charging section 23 for executing a charging system. , A display unit 25 for displaying the state of execution such as identification, billing or telephone number, a push-type dial 26, and the handset 1 are physically and
It comprises an electric circuit having a main body side connector 21 for electrically coupling and separating.

As shown in FIG. 2, the handset side connector 11 of the handset 1 of the present invention and the main body side connector 21 of the public telephone body 2 are physically and electrically connected to each other,
Execution of the public telephone system of the present invention is started. By this connection, the type of the handset 1 of the present invention is determined by the identification unit 22, and then the charging system such as cash, prepaid, credit, etc. is determined by the charging unit 23. Thereafter, the mobile phone enters an off-hook state, and a telephone number or the like is input by the push-type dial 26, thereby enabling a two-way communication, and a charging system is started. After the intercom is over, the handset side connector 11
, The execution of the charging system is terminated, and at the same time, the on-hook state is set.

The billing system is implemented in such a manner that the telephone charges are settled at every very short unit time so that the intercom can be on-hook at any time by separating the handset 11 connector.

Further, a memory 11 and a speaker are provided in a portion where a microphone and a speaker of a mobile phone or the like can be used independently.
By incorporating the cord 15 and the handset side connector 11, the present invention can be applied to communication equipment. By storing a telephone number and the like in the memory 11, automatic dial input and credit accounting can be performed.

[0014]

According to the present invention, the handset of the public telephone can ensure a good hygiene condition on the user side, which greatly contributes to the use of the public telephone system. The handset of the present invention can be made compactly with light and inexpensive materials such as paper and plastic, and can be made simple and compact as an electric circuit. Can be. In particular, it can be determined that the effect is great at an installation place such as a hospital.

[0015] Further, even if the user of the mobile phone at all times can use the handset as an handset of the present invention in an emergency, the telephone can be talked in the same sense as usual by simply connecting the connector, and the bill is automatically charged. is there.
