Abstract

PURPOSE:To make the card small in size by adopting the constitution such that an extension register storing an additional function is built in and the function is extended by using call enable information from the card when the card is loaded externally. CONSTITUTION:An extended register 6 as well as a standard register 5 is coupled directly with a system control section 4 and when a card 8 is loaded, a card detection section 7 detects call enable information of the extended register 6 possessed by the card 8 and informs the information to the system control section 4 to open the gate of the system control section 4 to the extended register 6 in the passing state. In this case, since the card has only to have the call enable information of the extended register, even when the storage information is lost in the volatile memory card, the information is easily written. Thus, the size of the card is made small, the handling is made convenient and the economy or the like is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multifunctional communication terminal device that has additional functions in addition to basic functions and enables the additional functions by installing a card.

[Conventional technology]

Conventionally, this type of communication terminal device has a memory card as a card, and when the memory card is inserted, the additional function is performed by extracting and making full use of the program and data of the additional function stored in the memory card. was.

FIG. 2 is a block diagram showing a conventional example.

In FIG. 2, the communication terminal device includes a transmitting/receiving section 11 a communication control section 2. Network control unit 3. Standard register5. System control unit 1
0 and a card connection section 11, and a memory card 20 including an expansion register 12 is removably attachable to the card connection section 11.

The transmitting/receiving section 1 has a facsimile function using a telephone circuit, a handset, an image reading circuit, and an image printing circuit. For example, when a call is made, the communication control unit 2 detects the call, makes the call to the communication line 9 via the network control unit 3, sends a designated dial number, and sounds a readout signal when the call is received. . Network control unit 3
monitors the communication line 9, notifies you when it detects an incoming call, connects the communication line 9, and also connects the communication line 9 when making a call.
is connected to the communication control unit 2. The standard register 5 stores, for example, the final dialed number as a basic function, and also stores the telephone numbers for 50 lines, and displays them on a display section (not shown) in response to a call from the system control section 10, and also displays them on a display section (not shown) in response to a call from the system control section 10. Used as the dialed number when reading a call from 2. The system control unit 10 executes writing and reading of information to and from registers according to the operator's operations, and also exchanges information with the communication control unit 2. Further, the system control i10 connects the expansion register 12 in the same manner as the standard register 5 when the memory card 20 is attached to the card connection section 11.

The expansion register 12 can expand and store telephone numbers for, for example, 100 lines, and also allows confidential reception of messages.

Furthermore, the memory card 20 having the expansion register 12 has stored information in a non-volatile structure using a battery.

[Problem to be solved by the invention]

As mentioned above, conventional communication terminal devices store extended function information in non-volatile memory cards, so as the memory cards become larger and more expensive, they become inconvenient to handle and less economical. There was a problem with it being bad.

SUMMARY OF THE INVENTION An object of the present invention is to provide a communication terminal device that solves the above-mentioned problems by making the card smaller by storing extended function information in the main body in advance.

[Means to solve the problem]

A communication terminal device according to the present invention includes a standard register having a storage area for standard programs and data for basic functions, and at least one expansion register having a storage area for expansion programs and data for functions added to and expanded to the basic functions. and a card detection section that detects and outputs at least the card type when a card is inserted, and normally connected only to the standard register when there is no output from this card detection section, and when receiving card detection information. and a system control unit that connects a predetermined extended register in addition to the standard register according to card detection information.

〔Example〕

Next, a communication terminal device according to the present invention will be explained with reference to FIG.

FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, the same components as those explained in FIG. 2 as the prior art are given the same numbers and symbols, and the explanation thereof will be omitted.

In FIG. 1, the communication terminal device includes a transmitting/receiving section 12 and a communication control section 2.
．． Network control unit 3. System control unit 4. Standard register5. It has an extension register (A) 6 and a card detection section 7, and a card 8 is attached to the card detection section 7.

The difference between this embodiment and the conventional example is that the system control unit 4 directly connects an extension register (A) 6 in addition to the standard register 5;
It can be called using information from the card detection section 7. When the card 8 is inserted, the card detection unit 7 detects information held by the card 8, for example, call permission information of the extension register (A) 6, and notifies the system control unit 4 of the extension register of the system control unit 4. (A) Open the gate to 6 to pass state.

Since the card 8 only needs to have the call permission information of the expansion register (A) 6, it is easy to write even if the stored information disappears in a volatile memory card, and even if the information is punched, the card detection section Any means may be used as long as it can be detected by 7.

In Figure 1, only the extension register (A) is illustrated and explained, but if multiple extension registers are provided for each additional function and used to permit and restrict the extension functions, it is possible to extend and restrict the functions used by the personal card. Limitation becomes possible.

〔Effect of the invention〕

As explained above, according to the communication terminal device of the present invention,
In addition to the standard registers that store basic functions, there are built-in expansion registers that store additional functions, and when a card is inserted from the outside, the functions are expanded based on the call permission information from the card, so the operator can maintain and handle them. The effect is that the card can be miniaturized, handling becomes convenient, and economical efficiency is improved.
