Abstract

PURPOSE:To display a large quantity of data to many persons at one time by displaying the data read out of IC cards and the arithmetic results on an external large-size display. CONSTITUTION:The input data received from a key output part 2 or the information on an IC card 8 are usually processed by an internal arithmetic part 11 of a main body 1. This processing result, etc., are displayed at a display part 3 of the main body 1. In case an external display 7 is connected to an external output terminal 5, the change of a display device is supplied from the part. Thus the information to be displayed at the part 3 is stored in a memory part 13 of the main body 1 by an amount equivalent to the display value of a display 7. Then the memory contents of the part 13 are converted into video signals and sent to the display 7 via a signal cable 6. The display 7 is demodulated by its own circuit and displays images. In such a way, a large quantity of information can be displayed to many persons at one time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is for displaying arithmetic results based on input data from a key input unit and information written in an IC card on an external display device such as a home television. The present invention relates to a mobile terminal device used for carrying out such operations.

BACKGROUND OF THE INVENTION Conventionally, this type of mobile terminal device has been equipped with a key input section, a calculation section, a display section, a storage section, and an IC card reading/writing section. The device is configured to perform calculations and read/write 5 to and from an IC card, and display the results and contents on a display section provided on the surface of the device.

Problems to be Solved by the Invention However, in the above-mentioned conventional mobile terminal devices, the display section built into the device cannot be made larger than a certain degree due to convenience in carrying and restrictions on the overall size of the device. ,
Therefore, there are problems in that the amount of information that can be displayed cannot be increased and that it can only be viewed by a small number of people.

The present invention solves these conventional problems and makes it possible to display data read from an IC card and calculation results on an external large display device such as a home television.
Therefore, it is an object of the present invention to provide a mobile terminal device that can display and view information at the same time, expand the amount of information, and allow many people to view it at the same time. .

Means for Solving the Problems In order to solve the above problems, the present invention provides a key input section and an I.
It is equipped with a C card reading/writing section, an arithmetic section, a representation section, a storage section, an output section for an external display, and an output terminal.

Effects The present invention has the following effects due to the above structure.

In other words, when the key is operated manually or when reading/writing an IC card, it is displayed on its own display, and when a display device is connected to the external display output terminal, the output is displayed on its own display according to instructions from the key input section. Information corresponding to multiple screens can be stored in the storage section, modulated into a video signal by the external display output section, and transmitted to an external display device for display.

Examples Examples of the present invention will be described below with reference to the drawings.
I will clarify. 1 and 2 show a portable terminal device according to an embodiment of the present invention, with FIG. 1 being an external perspective view for explaining the state of use, and FIG. 2 being a block circuit diagram.

In FIG. 1, reference numeral 1 denotes the main body of the mobile terminal device, and various circuits such as an arithmetic unit 11, a storage unit 13, etc. are stored therein as will be described later. 2 is a key input section arranged in the lower half of the main body 1; 3 is a display section provided in the middle part of the main body 1;
Reference numeral 4 indicates a reading/writing section for the IC card 8 provided at the top of the main body 1, 5 indicates an output terminal for an external display 7 provided at the lower end of the main body 1, and 6 indicates an output terminal □ terminal 5 and the external display 7. It is a signal transmission cable that connects the

In Figure 2, 2.3.4.5 are a key input section, a display section, an IC card reading/writing section, an external output terminal, and 1, respectively.
1 is an arithmetic unit, 12 is a display output circuit, 13 is a storage unit, 14
is the external display output circuit.

Next, the operation of the above embodiment will be explained. Normally, input data from the key input section 2 is processed by the calculation section 11 inside the main body 1, and the results etc. are displayed on the display section 3. Further, information read from the IC card 8 by the IC card reading/writing section 4 is similarly processed by the calculation section 11 and displayed on the display section 3.

On the other hand, by inputting a display device change input from the key input section 2, information to be displayed on the display section 3 of the main body 1 is displayed on the storage section 1 inside the main body 1 in an amount corresponding to the display amount of the external display 7.
Accumulate in 3. The contents of this storage section 13 are converted into a video signal by an external display output circuit 14 and output to an external output terminal 6. From external output terminal 5 to external display 7
The external display 7 demodulates the received signal using its own circuit and displays the image.

Effects of the Invention As described above, according to the present invention, the key input section and the IC
A card reading/writing section, a calculation section, a display section, a storage section, and an output section for an external display.

Since it is equipped with an input terminal and an output terminal, the output information for multiple screens of the own display unit is stored in the storage unit according to instructions from the key input unit, and is modulated into a video signal by the external display output unit, and output to the external display device. can be transmitted and displayed. Therefore, a large amount of information can be displayed at once. Additionally, displays that could previously only be viewed by a small number of people nearby can now be shown to many people at once.
