DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone capable of changing the type of telephone according to the situation.

[0002]

2. Description of the Related Art Heretofore, there has been proposed a so-called compatible device in which a portion of a cellular telephone and a cordless telephone are made common and a cellular cordless telephone is used (Japanese Patent Laid-Open No. 3-1621).

Further, a control device which is detachable from a communication terminal device including a telephone, a facsimile or the like has been proposed (Japanese Patent Laid-Open No. Hei 4-23).
652). The device outputs data from an electronic device to a communication terminal device in response to an input from a keyboard provided on a detachable electronic device.

[0004]

However, the former compatible device is a cellular phone having a cellular radio channel, cellular transceiver means and control means, and a cordless telephone having a cordless radio channel, cordless transceiver means and control means. It has both, and generally has to have two physical circuits and the like, which increases the weight and capacity, and is inevitably impractical as a portable telephone.

Although the control device is made detachable from the communication terminal device as in the latter case, a portion such as a microphone and a speaker needs to be provided on the communication terminal device main body only for a telephone. The system is not configured to be compatible with a plurality of different telephone systems. Therefore, as in the former case, there is a problem that physical double investment cannot be avoided.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to solve these problems of the prior art and to provide a telephone system having different line physical media and call control processes such as a wired telephone, a cordless telephone, and a cellular telephone. In addition, the present invention provides a configuration of a telephone that can change the type of telephone according to the situation.

In order to solve the above-mentioned problems of the prior art, the present invention provides a telephone body having at least a system control unit, a voice processing unit, an operation / display interface, an operation unit and a display unit, and is detachable from the telephone body. In the system comprising at least a line processing unit and a detachable unit having a call control unit, the system control unit of the telephone body includes a common interface that can be used in common with a plurality of different telephone systems,
A telephone functioning as a telephone belonging to a telephone system corresponding to a type of a line processing unit and a call control unit in a state where the detachable unit is connected, wherein the system control unit performs the line processing unit and the call control through a common interface when power is turned on. The process of checking the presence or absence and type of the unit and informing the user whether or not it can be used as a telephone is performed.

[0008]

According to the above-mentioned structure, the telephone main body is integrated with mechanical parts commonly provided in any telephone system, and a control section or the like corresponding to each telephone system is integrated into a detachable portion. By simply connecting these detachable parts to the telephone body, the telephone body operates according to the telephone system corresponding to the detachable part by the common interface of the system control unit of the telephone body, and functions as a telephone as a whole.

[0009]

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

FIG. 1 is a block diagram showing the configuration of the telephone according to the present invention. The portion within the dotted line is the portion 2 that is detachable from the telephone body, and the other is the telephone body. The detachable part 2
Absorbs the difference between the type of physical medium of the line and the call control. Further, one part is an interface with the detachable part 2 of the telephone body, which is common to various telephones. Reference numeral 3 denotes a system control unit, 4 denotes a line processing unit, 5 denotes a call control unit, 6 denotes a voice processing unit, 7 denotes an operation / display interface, 8 denotes an operation unit, and 9 denotes a display unit. First, when the power of the telephone is turned on, the system control unit 3 performs a check operation through the common interface 1 to check the presence / absence and type of the line control unit 4 and the call control unit 5 to determine whether the telephone can be used. After the inspection, the user is informed of the type of the currently connected telephone and whether or not the telephone can be used by means such as display, sound, and voice. After that, it can be used as a normal telephone.

[0011] Further, by providing personal identification information in a common part (a part other than the detachable part) and a personal information registering means in a telephone exchange to which a telephone is connected (an intra-office exchange or a private branch exchange), personalized information can be provided. Management as a telephone (such as management of individual billing) is also possible.

In addition, a public telephone is provided with a line processing unit and a call control for the public telephone, a public telephone is provided with a common interface, and each user has a common unit. Connect the common part of individuals to
It is also conceivable to use.

[0013]

As described above, according to the configuration and method of the present invention, (1) a detachable portion can be installed even in a telephone having a different physical medium or a different call control process in a line such as a wired telephone, a cordless telephone, and a cellular telephone. By exchanging, you can select the type of telephone according to the situation and make a call.

(2) Multiple investments in common parts of the telephone can be avoided.
