Abstract

PURPOSE:To enable personal control of an ordinary RAM card by executing specific processing when a read out pass word and the inputted pass word are collated and coincide with each other. CONSTITUTION:An operator is requested to input the pass word from a keyboard 4 via a display part 5 in the case of not an initialize processing. The end of the input of the pass word is waited and the respective inputted pass words are stored into a pass word buffer 31. The content in a region 61 of a pass word register of the RAM card 6 is read out via a card interface 7 when the input of the pass word ends. The read content of the region 61 of the pass word register and the pass word stored in the buffer 31 are collated. The data access of the RAM card 6 is enabled when the coincidence of the collation is obtd.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an electronic device in which a storage pack is configured to be detachable. Related to electronic devices whose contents can be read and written only by certain people.

[Prior Art] With the recent advances in LSI technology, card-shaped or pack-shaped external memories using RAM have become easily available. These RAM cards, RAM packs (
RAM cards (hereinafter collectively referred to as RAM cards) have insufficient capacity, but unlike cassette tapes and the like, they have no moving parts and can read and write contents quickly and randomly. Moreover, since the electrical and mechanical interface with the main body of the device is simple, it is expected that it will become increasingly popular as a simple external storage means for low-cost word processors and the like. However, although it is a simple external memory, the information recorded there is important to individual users. Moreover, it is a portable RA.
Since it is an M card, it is thought that there will be a demand for individuals to use a dedicated RAM card. However, conventionally,
Any number of people could read and write this type of RAM card. Therefore, the contents can be easily known by people other than the user,
In addition, important data is often lost due to careless operations.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned drawbacks of the prior art.
The purpose is to provide an electronic device that allows personal management of AM cards.

[Means for Solving the Problems] In order to achieve the above object, the electronic device of the present invention includes an input means for inputting data, a reading means for reading out a password from a predetermined position of the attached memory pack, and the input means. branching means for determining a branch to a corresponding process according to input processing request data; a control means for requesting input of a password from the input means when the branching means has decided to branch to a specific process; a verification means for verifying the password read by the reading means when the control means requests input of a password and a password input from the input means; and a verification means for verifying the password inputted from the input means when the control means requests input of a password; A processing means is provided to execute the determined specific processing.

[Operation] In this configuration, the operator inputs various processing request data (processing execution commands) via the input means. The branching means determines branching to a corresponding process according to the processing request data inputted by the inputting means. In this case, the control means requests input of a password from the input means because the branching means has decided to branch to a prespecified process (for example, a process related to reading or writing a RAM card). When the control means requests input of a password, the verification means verifies the password read from a predetermined location of the RAM card by the successive output means and the password input from the input means.

Next, the processing means executes the specific process determined by the branching means when a match is obtained in the verification by the matching means.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a word processor according to an embodiment. In FIG. 0, reference numeral 1 denotes a central unit that executes document creation MA collection processing, print processing, and RAM card handling processing according to the present invention as a normal word processor. Processing unit (CPU), 2 is CPU1
A read-only memory (ROM) that stores the card processing procedure shown in FIG. 2, for example, is a program executed by
, 3 is a random access memory (RAM) that stores various data necessary for the program execution of the CPU 1; 4 is a keyboard used for inputting document data, inputting various processing execution commands, and inputting passwords to be described later; 5 is a display unit that displays document data, etc., 6 is a RAM card used as an external storage device, and 7 is a CPU I and RAM card 6.
8 is a printer for printing the created document data, and 9 is a common bus for the CPUI.

The RAM card 6 has a built-in power battery, and the data stored in the RAM card is preserved even if it is removed from the word processor main body. Further, a predetermined area of the RAM card can be used as the password register area 61. For example, when the RAM card is used as a document file, a password can be registered in the password register area 61.

Further, in the RAM 3, 31 is a password buffer that temporarily stores the password input from the keyboard 4 for verification or to record it in the password register area 61 of the RAM card.

FIG. 2 is a flowchart of the card processing procedure of the embodiment. The process shown in the figure is entered, for example, when one of the processes displayed on the menu on the display section 5 is selected using the keyboard.

In step S1, key input is captured. In step S2, it is determined whether the input key input is a request for initializing the RAM card as a document file. In this embodiment, initializing the RAM card is a normal process that does not require a password. ,
Other processes are specific processes that require a password. If it is determined in step S2 that it is not the initialization process, the process proceeds to step S3, in which the operator is requested to input a password from the keyboard 4 via the display unit 5.

In step S4, the end of password input is waited for, and each input word is stored in the password buffer 31. When the password input is completed in step S4, the contents of the password register area 61 of the RAM card 6 are read via the card interface 7 in step S5. In step S6, the content of the read password register area 61 is compared with the password stored in the password buffer 31 in step S4, and if a match is obtained, data access to the RAM card 6 is enabled in step S7. In this case, the RAM card 6 is used for the purpose of creating an MA collection or reading document data. Further, if no match is obtained in step S6, the screen returns to the menu screen, for example.

Ordinary RAM, such as when an operator inserts another person's document card or is used for purposes other than document cards.
If a card is inserted, a match cannot be obtained.

Furthermore, if it is determined in step S2 that the process is to initialize a RAM card, no password is required to be input. The flow advances to step S8, where the contents of the RAM card 6 are all cleared with a null code or zero code, and then predetermined formatting processing such as creation of a file header section for making a document card is performed, and step S9 prompts the operator to enter a password. In step S10, the end of password input is awaited, and in this case, each word is temporarily stored in the password buffer 31 of the RAM 3.
For example, this content can be displayed on the display unit 5 so that the operator can confirm the input. When the password input is completed in step S10, the contents of the password buffer 31 are written into the password register area 61 of the RAM card 6 in step 311.

[Effects of the Invention] As described above, according to the present invention, the ordinary R
It becomes possible to personally manage the AM card, and it is possible to prevent the contents from being easily known by a person other than the user, and from losing important personal data due to careless operation.

Moreover, you can specify the processes that require a password, so
Operators are only required to enter a password when performing specific operations, and can use electronic devices as they wish for other operations.
