Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card-type cordless telephone system which uses a card storing a call frequency in a cordless telephone and enables a call only while there is a remaining call number.

[0002]

2. Description of the Related Art Conventionally, as a card type telephone system in which a card storing a call frequency is used and a call charge is deducted from the card, both a wired telephone and a wireless telephone,
The phone had a built-in card reader.

[0003]

Therefore, in the case of a wired telephone, it is necessary to move to the place where the telephone is installed each time a call is made, and in the case of a wireless telephone, when moving during a call, a card is used. Since it was equipped with a reader, it was necessary to carry a wireless telephone that was heavier and larger in size than ordinary cordless telephones.

In addition, when changing the installation location of the telephone in the building (mainly the parent device when the device is divided into the parent device and the child device), it is necessary to change the wiring. Further, when the owner of the telephone line and the telephone user are different, the owner could not settle his / her own call charge immediately after knowing the call detail information after the call of the telephone user was finished.

It is an object of the present invention, after the card is inserted into the card reader, even if only the handset which is separate from the card reader portion is held away from the card reader portion,
You can call wirelessly at any place, and you can make a call by card payment according to the billing system uniquely set by the telephone line owner, and you can get the charge details immediately and install the card reader part It is to provide a novel card-type cordless telephone system that can be changed freely without changing wiring.

[0006]

According to the present invention, a repeater connected to a telephone line, a display with a card reader for wirelessly transmitting and receiving with the repeater, and a handset for wirelessly transmitting and receiving with the display are provided. Then, insert a card that stores the call frequency into the display and read the remaining number on the display, and if there is a remaining number, enable transmission and reception between the handset and repeater via the display Billing information is created, the billing information is transmitted to the display unit, the remaining number of cards is subtracted on the display unit, and transmission / reception between the handset, the display unit, and the repeater is ensured while the remaining number is present.

[0007]

According to the present invention, the repeater is a master unit, the display unit with a card reader is a slave unit, and the handset is a grandson unit. When a card is inserted into the slave unit (display unit with a card reader), Wireless transmission and reception is possible among these three separated units, and only the grandchild unit (handset) can be carried to communicate with an outside line from a free place. Telephone charges can be charged by withdrawing from the card according to the billing system stored in the base unit (repeater). One base unit (repeater)
Multiple handset units (displays with card readers) and multiple handset units (handsets) can be used for one handset, and an organic network can be built in the same building. it can.

[0008]

EXAMPLE An example of the present invention will be described below.
In the card type cordless telephone system according to the present invention, a repeater 2 connected to a general telephone line 1, a display 3 with a card reader for wirelessly transmitting and receiving with the repeater 2, and this display 3
And a handset 4 that transmits and receives wirelessly. Then, the repeater 2 is, so to speak, a master device, and a display device 3 with a card reader.
Is a slave unit, and the handset 4 is like a grandson unit, and a plurality of display devices 3 with a card reader are provided for one repeater 2.
Furthermore, a plurality of handsets 4 can be used for one display 3.

The repeater 2 is provided with a number-based charge index table (storage device) that stores a charge system for each phone number, and the phone number is wirelessly transmitted from the handset 4 through the display 3. Then, the telephone number is sent to the telephone line 1 to connect to the outside line, and the billing information is wirelessly transmitted to the display device 3 by referring to the number-based billing index table corresponding to the telephone number.

The display 3 has a built-in card reader,
When the card 5 storing the call count is inserted, the remaining count is read and subtracted from the card based on the billing information transmitted from the repeater 2, and the call can be made to the repeater 2 while the remaining count remains. Send a signal. Further, the display device 3 generates a warning sound when the frequency of the card runs out, and sends a call interruption signal to the relay device 2 to stop the call when the next card is not inserted. The display unit 3 has a display unit 6 made of liquid crystal or the like, and displays the remaining number of the card 5, the call time, the telephone number and the like.

The handset 4 is provided with a push button and also has a wireless transmission and reception function. In this handset 4, when a push button is pressed to input a telephone number, the telephone number is wirelessly transmitted to the relay 2 via the display 3 and is connected to the outside line through the telephone line 1 by the relay 2. Then, until the frequency of the card 5 inserted in the display device 3 is exhausted, it is possible to wirelessly transmit and receive an external line via the relay device 2 and the display device 3.

If the display unit 3 is provided with a charger for charging the storage device of the handset 4, even if the handset 4 is used without a power line and a telephone line, a call to an outside line can be made. it can.

[0013]

The present invention has the following effects. After inserting the card into the display with card reader,
Even if you have only the handset that is separate from the display unit and leave the display unit, you can wirelessly communicate in a free place. Since the billing information is sent to the display device wirelessly from the repeater connected to the telephone rotation, it is possible to make a call by card payment according to the billing system that the telephone line owner independently establishes, and obtain the bill details immediately. . Therefore, it can be used for rental business of cardless cordless telephones.

Since it is possible to freely change the installation position of the display with a card reader as well as the handset without changing the wiring, that is, from the service entrance of the telephone line to the telephone (display and handset) in the building. Since no wiring is required, it can be used for telephone rental business such as rental houses and rental buildings. It can be used as a card including functions such as entry / exit control in the building, communication terminal connection keys, and credits for purchasing goods, and can be used together with intelligent building management.
