Abstract

PROBLEM TO BE SOLVED: To attain data transfer from a portable terminal regardless of the capacity of a battery, and to prevent the disconnection of a line during data transfer by providing a commercial power supply device for supplying power during data transfer in a public telephone device for operating communication through a public line by a portable terminal. SOLUTION: By inputting a telephone card or coins, the start of power supply is notified from a controller 1-8 to the charging host computer of a telephone company. Moreover, the start of power supply is instructed to a commercial power supplying device 1-7. The commercial power supplying device 1-7 receives the instruction of the start of power supply, and starts power supply to a portable terminal. After dialing from the portable terminal to the other party, communication through a public line 2 can be attained, and communication with the other side is started. Then, the controller 1-8 operates the fair adjustment of a power fee and communication fee during communication by a telephone card device 1-1 or a coin accepting device 1-2, and repeats this operation during operation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a public telephone device for supplying power to a portable terminal communicating via a public line.

[0002]

2. Description of the Related Art Generally, a conventional public telephone device has a modular jack for data transfer, but power is not supplied to a portable terminal at the time of data transfer. That is the current situation.

[0003]

Therefore, in the device having the above configuration, when data transfer is performed using a portable terminal,
Since the capacity of the built-in battery is too small to perform a sufficient operation, there is a problem that all data cannot be transferred.

[0004]

A public telephone device for performing communication from a portable terminal via a public line is provided with a commercial power supply device for supplying power during data transfer, and a power supply during data transfer from the portable terminal is provided. To prevent disconnection of the line during data transfer.

[0005]

FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, a control device 1-8 of the public telephone device 1 includes a telephone card device 1-1, a coin receiving device 1-2, a data transfer device 1-3, a communication device 1-4, and a display device 1. -5, input device 1-6, commercial power supply device 1-7
Are connected to an external public line 2 and a commercial power supply 3.

In the current public telephone device, devices other than the commercial power supply device 1-7 are already included in the device configuration.

FIG. 2 is a flowchart showing the operation of the embodiment of the present invention.

The operation will be described below with reference to FIGS.

(1) First, the modular and the power outlet of the portable terminal are connected to the public telephone device 1 of FIG. next,
When a telephone card or a coin is inserted, the control device 1-8 in FIG. 1 sends a power supply start notification to the charging host computer of the telephone company. Further, it instructs the commercial power supply device 1-7 of FIG. 1 to start supplying power.

The commercial power supply 1-7 shown in FIG. 1 starts supplying power to the portable terminal upon receiving the start instruction.

(2) After dialing from the portable terminal to the other party, it becomes possible to talk via the public line 2 in FIG. 1 and start communication with the other party. At that time, the control device 1-8 in FIG. 1 adjusts the power usage fee and the communication fee during the communication time by the telephone card device 1-1 or the coin receiving device 1-2 in FIG. 1, and repeats this operation during a call. .

(3) When the communication is completed, the communication completion is notified to the accounting host computer of the telephone company.
The communication completion is also notified to the control device 1-8. In response to this, an instruction to stop power supply is issued to the commercial power supply device 1-7 in FIG. 1, and the commercial power supply device 1-7 in FIG. 1 stops power supply to the portable terminal. Thereafter, the control device 1-8 in FIG. 1 instructs the telephone card device 1-1 and the coin receiving device 1-2 in FIG. 1 to eject the medium.

The telephone card device 1-1 and the coin receiving device 1-2 of FIG. 1 return the medium and complete all the operations.

[0015]

As described above, according to the present invention,
By supplying commercial power, data transfer from the portable terminal can be performed without considering the capacity of the battery, so that an effect of preventing disconnection of the line during data transfer can be obtained.
