Abstract

PURPOSE:To transmit/receive data to/from a host computer through a telephone circuit without using a telephone set by providing a function which automatically converts the dial number inputted with ten keys to a dial code and transmits this code. CONSTITUTION:A connector 1 is inserted to the receptacle of the telephone circuit and a dial key 7 is depressed, and the dial number of an opposite party is inputted with ten keys 6, and then, a dial part 4 is operated and a portable terminal and the host computer are connected to set the online state. When then keys 6 are used to input data, input data is displayed on a display part 5 and stored in a communication control part 2. When a transmission key 8 is next depressed, a modulating/demodulating part 3 is operated and data stored in the communication control part 2 is modulated and transmitted to the host computer. Reception data from the host computer is demodulated by the modulating/demodulating part 3 and stored in the communication control part 2 and displayed on the display part 5. Thus, data is transmitted/received between the portable terminal and the host computer through the telephone circuit with out using a telephone set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to information processing equipment, and particularly to a portable terminal device that transmits and receives data to and from a host computer.

[Conventional technology]

Conventional means for transmitting and receiving data between a portable terminal device (portable terminal) and a host computer is performed by connecting the portable terminal to a telephone and via a telephone line.

[Problem to be solved by the invention]

As described above, the conventional means for transmitting and receiving data between the portable terminal and the host computer uses a telephone, which has the disadvantage that a telephone must always be prepared outside the portable terminal.

[Means to solve the problem]

The portable terminal of the present invention has a built-in dialing function in the main body of the portable terminal, so that a host computer can be connected to the portable terminal to send and receive data.

That is, the portable terminal of the present invention has a numeric keypad consisting of numeric keys, a dial key that gives a command to convert a dial number inputted into the numeric keypad into a dial code, a send key that gives a command to send data inputted to the numeric keypad, and the above-mentioned transmission key. a keyboard having a display section that displays data entered on the numeric keypad or data received;
a dial unit that converts a dial number input into the keyboard into the dial code according to a command from the dial key and transmits the dial code; a communication control unit that stores data input into the keyboard and data received from the host computer; a modulation/demodulation section that modulates and transmits data stored in the control section, receives data from the host computer, demodulates it, and sends it to the communication control section; and a modulation/demodulation section that is inserted into a telephone line connector to connect to the host computer. It is equipped with a connector.

〔Example〕 Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a plan view showing the keyboard of the embodiment of FIG.

In FIGS. 1 and 2, a connector 1 is a connector that is inserted into a telephone line connector for connection.

The communication control unit 2 is a buffer memory for transmission and reception. The modulation/demodulation unit 3 is a device that modulates and demodulates signals for transmission and reception. The dial unit 4 is a device that has a dial function for connecting the portable terminal 10 and a host computer to bring them online. The display unit 5 is a screen for displaying the contents of the transmitted and received data. The numeric keypad 6 is a number key for inputting the dial number of the other party. The dial key 7 is a key for switching the dial number input into the numeric keypad 6 into a dial code. The transmission key 8 is a key for starting data transmission.

Next, the operation of this embodiment will be explained.

When the connector 1 is plugged into a telephone line outlet, the dial key 7 is pressed, and the dial number of the other party is entered using the numeric keypad 6, the dial section 4 is activated to establish a connection between the portable terminal and the host computer, and the system becomes online. . Next, when data is input using the numeric keypad 6, the input data is stored in the communication control unit 2 when it is displayed on the display unit 5. Next, when the transmit key 8 is pressed, the modulation/demodulation section 3 operates, modulating the data stored in the communication control section 2, and transmitting the modulated data to the host computer. The data received from the host computer is demodulated by the modem section 3, stored in the communication control section 2, and displayed on the display section 5.

〔Effect of the invention〕

As explained above, the portable terminal of the present invention has the function of automatically converting the dial number entered from the numeric keypad into a dial code and transmitting it, so that it can communicate with the host computer via the telephone line without using a telephone. This has the effect of being able to send and receive data.
