Abstract

PURPOSE:To utilize effectively a terminal equipment having plural functions by collating the pre-recorded data in the data memory of an IC card and that supplied from the data terminal equipment, and activating the said terminal equipment if the two coincide with each other. CONSTITUTION:The operator inserts one's own IC card 1 into a card reader/ writer 15, inputs the pass word number from a keyboard 12 and the inputted number is collated with one in the card 1. If coincidence of the two results, functions 1-N and service conditions 1-N are read out from the PROM of the card 1, which are stored in a RAM18 of a data terminal equipment main body 11 via the reader/writer 15. If the operator inputs from the keyboard 12 a desired function and the service condition, a CPU16 collates the functions and service conditions stored in the RAM18 and those in the card 1, and if the two coincide with each other, activates the correspondent function of the main body 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention is applicable to a so-called IC card in the case where, for example, one data terminal device has the functions of an online terminal and a function of a personal computer.

[Technical background of the invention and its problems] The majority of recent data terminal devices are CPIJ (
It has a central processing unit (Central Processing Unit) and achieves multiple functions by incorporating multiple application programs. However, not all terminal operators are qualified to use these applications. In the case of using a computer, it is necessary to set a key on the terminal device or to set operational restrictions such as telling the operator only the names of the application programs that can be used, which is extremely troublesome and incomplete. But there was.

[Purpose of the Invention] The present invention has been made in view of the above circumstances, and its purpose is to automatically perform only the functions authorized by the operator in electronic equipment such as data terminal devices that have multiple functions. The objective is to provide electronic equipment that can be selected easily and reliably.

[Summary of the Invention] In order to achieve the above object, the present invention is configured so that function selection can be performed using data hidden in a portable medium such as an IC card.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

It is electrically connected to a card reader/writer to be described later. For example, as shown in FIG. 2, the IC chip 2 includes a CPU 4 as a control element that decodes, calculates, and stores commands, data, etc. sent from the card reader/writer via the connection section 3;
It is constituted by a PROM (Programmable Read Only Memory) 5 as a data memory in which data processed by is recorded. The CPU 4 decodes commands sent via the connection unit 3, and
a control unit 6 that controls the operation of each part within the system; an arithmetic unit 7 that performs calculations as necessary depending on the type of instruction; a ROM (read-only memory) 8 that stores internal control programs and fixed data; RAM (Random Access Memory) 9 that temporarily stores instructions, data, etc.
It consists of

FIG. 3 shows a data terminal device as an example of an electronic device according to the present invention. That is, 11 is a data terminal device main body, which is equipped with a keyboard 12 for inputting data and a CRT display 13 for displaying data, and is connected to a card reader/writer 15 via a cable 14.
are electrically connected.

FIG. 4 shows the configuration of the data terminal device main body 11. As shown in FIG. That is, 16 is a CPU that controls each part and performs calculations, and 17 is a ROM that stores control programs.
, 18 is a RAM for temporarily storing data processed by the CPLJ 16, 19 is a data bus line connecting the CPU 16 and each part,
20 is a keyboard interface that connects the keyboard 12 and the data bus 19; 21 is a display interface that connects the display 13 and the data bus 19; and 22 is a connector that connects the data terminal device body 11 with a modem (not shown). A modem interface 23 is a card reader/writer interface that connects the card reader/writer 15 and the data bus 19.

FIG. 5 shows the configuration of the card reader/writer 15. As shown in FIG. That is, 24 is a CP that controls the operation of each part.
tJ, 25 is a ROM storing a control program, 2
6 is a terminal device interface that connects the CPL 124 to the data terminal device main body 11; 27 is a connecting portion electrically connected to the connecting portion 3 of the inserted IC card 1;
Reference numeral 8 denotes a card that controls writing and reading of data to and from the inserted IC card 1 via the connection section 27.
An interface 29 is a card drive unit that controls the transportation and connection of the inserted IC card 1, and 30 is a card controller that connects this card drive unit 29 with the CPtJ 24.

Next, the operation in the above configuration will be explained. First, the procedure for recording data on the IC card 1 will be explained with reference to the flowchart shown in FIG. The administrator of the data terminal device creates an IC card that records the functions that can be used by the terminal operator. The IC card creation program built into the data terminal device main body 11 is designed not to start without the administrator's password, so the administrator first inputs the password from the keyboard 12 (step S1). Next, each terminal operator enters a different password and available functions (step S).
2). The available functions may be, for example, the type of operating system or the type of business processing program of the terminal device. Furthermore, it is also possible to specify usage conditions for each function of the business processing program, such as allowing a receiving function but not a sending function.

In this way, when the data input is completed, the unrecorded IC inserted into the card reader/writer 15 at this time
The input data is recorded in the PROM 5 of the card 1 (step 83). The data recording situation in this PROM 5 is as shown in FIG.

Next, the operation when the terminal operator starts up the data terminal device main body 11 using the IC card 1 created as described above will be explained with reference to the flowchart shown in FIG. First, the operator inserts his/her IC card 1 into the card reader/writer 15 (step 84). Next, the password is inputted from the keyboard 12 and checked against the password in the IC card 1 (step 85). If both PIN numbers match, functions 1 to N and usage conditions 1 to N shown in Figure 6 will be activated.
are respectively read from the PROM 5 of the IC card 1 and sent to the data terminal device body 1 via the card reader/writer 15.
1 RAM 18 (step 36). Here, enter the functions and usage conditions desired by the terminal operator on the keyboard 1.
2, the CPU 16 checks the function in the RAM 18 and the usage conditions, and if the two match, activates the corresponding function of the data terminal device main body 11 (step 87
).

By configuring as described above, it is possible to automatically and reliably select only the functions authorized by the operator, especially in a multi-functional data terminal device, and also to ensure that unauthorized use of the data terminal device is prevented. It can be prevented.

Note that several types of IC cards with different functions and usage conditions recorded may be prepared, and when leasing a data terminal device, an IC card suitable for the fee and purpose may be provided together.

Further, although the above embodiments have been described with reference to data terminal devices, the present invention can also be applied to other electronic devices such as personal computers and word processors.

[Effects of the Invention] As detailed above, according to the present invention, in an electronic device such as a data terminal device having multiple functions, only the functions authorized by the operator can be automatically activated. It is possible to provide electronic devices that can be selected with certainty.
