Abstract

PURPOSE:To collect data accumulated in a card at high speed by connecting the corresponding data terminals of first and second external connecting terminals in plural LSI cards in which select terminals are provided separately to a card reader/writer by connecting subordinately. CONSTITUTION:The LSI card 1-1 in which the data is accumulated as the memory of a terminal 20 is loaded so as to connect its external connecting terminal 2 to the card reader/writer of the terminal 20, and furthermore, the external connecting part 2 of the LSI card 1-2 is connected to an external connecting part 3, then, the LSI card 1-3 is connected, and so on. The select terminal 8a is not connected to the external connecting part 3, and the select terminal 4b is connected to the select terminal 6a of the external connecting part 3 corresponding to the position of the select terminal 4a at the external connecting part 2 with a select line 8b. Thenceforth, the terminals 4c and 6b, and 4d and 6c are connected with each other with select lines 8c and 8d, respectively, then, the select terminal 6a goes to a null terminal. Thus, it is possible to collect the data in the cards 1-1 to 1-3 at high speed, and also, to easily perform the movement and editing of the card.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is intended to collect data stored in multiple LSI cards at high speed and without omission, or to collect data stored in multiple LSI cards without omission.
This relates to an LSI card suitable for moving and editing the card.

(Prior Art) The use of LSI cards (including those incorporating C20) as external memory for terminals such as personal computers is increasing. Here, it has become necessary to collect data accumulated in a plurality of LSI cards, or to move and edit data from a connected LSI card to any other LSI card.

Conventional LSI cards of this type can only be inserted into a card reader/writer one at a time, so multiple LSI cards can be inserted into the card reader/writer at the same time.
To collect card data, the LSI cards must be manually inserted into and removed from the card reader/writer as many times as the number of cards.

[Problem to be solved by the invention]

As a result, it took a long time to collect data and edit S-1. Furthermore, although it is easily possible to provide a card reader/writer with a plurality of storage locations for LSI cards, there is a drawback that the card reader/writer becomes larger accordingly. Note that the IC card unit disclosed in Japanese Patent Application No. 62-298933 and the non-contact coupled IC card (with a built-in CPU) are suitable for data collection, but cannot be easily distinguished visually. Move to the marked IC card.

Not suitable for editing. This is because the ID number of the IC card cannot always be visually determined.

The purpose of this invention is to connect LSI cards one after another to the LSI card connected to the card reader/writer of a terminal, instead of manually replacing multiple LSI cards one by one and inserting them into a card reader/writer. This provides an LSI card that is suitable for collecting data, collecting data, and collecting data by controlling the LSI card from the terminal using the number of the LSI card connected to the terminal.

(Means for Solving the Problems) An LSI card according to the present invention each includes a plurality of data terminals and a plurality of select terminals, and has a first external connection section to which a card reader/writer or an LSI card is connected, and a second external connection section. the corresponding data terminals of the first and second external connection parts are connected to each other by a bus line, and at least one select line connected to the select terminal of the first external connection part is connected to the select terminal of the first external connection part. The select function is provided without connecting to any of the select terminals of the second external connection part, and the first
The remaining select terminals of the external connection section and the select terminals other than one of the second external connection section are connected by select lines, respectively.

[Effect]

In this invention, when further connecting LSI cards one after another to the LSI card connected to the card reader/writer of the terminal, the select lines function as select lines in a sequentially shifted manner, so that each connected LSI card You can easily find out what position from the terminal it is. Therefore,
When collecting data from these LSI cards or editing data from a connected LSI card to any LSI card, it is especially easy to visually distinguish between <LSI
It becomes easy to move and edit a card, for example, the first LSI card from the terminal, or the third LSI card from the terminal marked in red.
