Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal system having a module configuration using wireless communication.

[0002]

2. Description of the Related Art As computers become smaller in size, personal computers (personal computers) are becoming more sophisticated and more sophisticated. In particular, miniaturization of mobile terminals such as notebook PCs, portable terminals, PDAs, etc. aimed at being carried and used outdoors, higher performance by mounting a CPU with a faster processing speed and a small and large-capacity HD, incorporating a digital camera, Character recognition, voice recognition, and the installation of a color display are highly remarkable.

Further, by connecting these mobile terminals to mobile communication devices such as PHSs and mobile phones, it is possible to read and write e-mails and access the Internet even when out of the office. It is also considered to be incorporated into. As described above, mobile terminals tend to be equipped with various functions so as to be compatible with various uses.

On the other hand, actual users use only some of these functions, and usually carry many useless functions and functions. For example, taking the processing speed of a CPU as an example, a user who mainly handles text and rarely handles images does not need a CPU that is so fast. In general, high-performance CPUs tend to consume more power, and even users who rarely handle images use extra batteries for unnecessary performance. In the case of a display device, color display is not so important in the case of text-based usage. However, mobile terminals are moving toward high-definition color displays, and as a result, power consumption tends to increase.

[0005] On the other hand, when the function that the user wants to use is not installed, the function is connected using a PC card. In this case, the feature of the mobile terminal that is compact is neglected. .

A personal computer is essentially a personal computer, and it is necessary to use a method suitable for an individual or a configuration corresponding to a different usage depending on the same individual. In particular, mobile terminals that are assumed to be carried around should have a more flexible hardware configuration that can easily remove unnecessary objects from the viewpoint of power consumption, portability, and risk of loss.

[0007]

However, in a conventional mobile terminal such as a notebook personal computer, in order to pack many functions in a smaller space, many functional elements are directly soldered on one board, and a memory is used. Only a very small part of the system can be added or replaced. As described above, there is a problem that a mobile terminal that is assumed to be carried has a hardware configuration that is rather difficult to customize as a result of miniaturization in consideration of portability.

In recent years, IC card systems capable of reading and writing data without contact have become widespread. There are several types of this non-contact IC card system, and a system using an AC magnetic field and a system using a microwave are typical. In an electromagnetic induction type system using an AC magnetic field, power required for operation of an IC card can be supplied from the R / W, and a system in which a battery is not mounted on the IC card can be configured. Currently, work on international standardization (ISO14443) is in progress.

In these IC card systems, when communication is performed from the R / W to the IC card, information is directly transmitted to the carrier generated by the R / W and transmitted. When communicating from the IC card to the R / W, in the electromagnetic induction type, the IC
Communication is carried by carrying information by changing the amount of current induced in the coil of the card and changing the magnetic field strength of the carrier. In the microwave type, the received power amount and re-radiated power amount of the carrier radiated by the R / W are changed by changing the reflection coefficient of the antenna inside the IC card,
As a result, the electric field strength of the carrier is changed, and communication is carried with information.

As described above, in the conventional non-contact IC card system, the IC card does not have a function of transmitting a signal by itself, and communicates by putting information on a carrier generated by the R / W.

[0011] Further, the conventional non-contact IC card is often used in a situation where a certain communication distance is required in an open situation such as entry / exit control, and as a result, the card is radiated from the R / W. Carriers are regulated by the Radio Law, etc., and the communication distance and communication speed are restricted.

An object of the present invention is to provide a terminal system that can easily customize hardware according to the purpose of use of an individual.

[0013]

According to the present invention, there is provided a carrier generating module for generating a carrier for performing wireless communication using an electromagnetic wave or a magnetic field, and the wireless communication interface and predetermined hardware constituting a terminal are provided. Wherein the carrier generation module and at least two of the function modules are stacked, and predetermined information is transmitted and received between the function modules using a carrier generated by the carrier generation module.

In the communication terminal TS1, similarly to the electromagnetic induction type non-contact IC card system, wireless communication using an AC magnetic field is performed, and the carrier generation module 81 continuously emits an unmodulated AC magnetic field and transmits information. The module changes the amount of current in the coil induced in the direction to cancel the magnetic field of the carrier according to Faraday's law by changing the value of the resistance called a load switch or changing the capacitance of the capacitor to the magnetic field strength of the carrier.

Further, the band of each antenna coil may be widened, and a plurality of channels may be assigned to one coil. In such a case, the same operation as that of the terminal system TS1 is performed.
