Abstract

PURPOSE:To easily know the process of addition and modification and to rewrite data on a write only nonvolatile memory medium by recording a rewrite history of memory information on a recording medium such as addition and correction so as to display the rewrite process on a screen. CONSTITUTION:When the remittee of a slip is rewritten, an altered and added information 22 is shown for an recording information memory part 2 with the aid of a newly added memory information existence 42, and identified by a memory information ID data 41. The same contents as the newly provided memory information ID data 41 are written on an existing additional information ID data 33, and the relative addresses from the top of a recording information 21 on an additional position indicating data 34, type-by-type information on an additional type-by-type data 35 and the data length of a recording information 21 to be rewritten on a rewrite target data length 36 are written respectively. The restoration processing of recording information is displayed on the screen in wrtie order, thereby showing ther rewrite history visually.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an information storage and reuse system, and particularly to an information storage and reuse method suitable for storage and reuse of information that requires a history of information addition and modification.

[Background of the invention]

With conventional information recording media such as magnetic cards and IC cards,
Although consideration was given to the writing of incorrect information and unauthorized changes to information, no consideration was given to the history of rewriting (additions and corrections) of stored information. Conventionally, as shown in Japanese Patent Application Laid-open No. 59-168586, etc.,
Although it is stated that in an IC card, which is a non-volatile storage device, information is reliably stored by sending an information save signal, there is no mention of a method for storing rewrite history.

[Purpose of the invention]

An object of the present invention is to provide an information storage and reuse method in an information storage and reuse system for information recording media, which retains a history of rewrites such as information additions and modifications, and visually displays the rewrite history as necessary. is intended to provide.

[Summary of the invention]

In the present invention, when storing information, the additional information ID data, additional information position instruction data, additional information type data, and rewriting target data length are held together with the storage information ID data,
The feature is that the rewriting history is managed using each piece of data, and when restoring information after rewriting, it is visually restored and displayed in the order in which it was rewritten.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 1 shows a state in which the A slip 1 is input and the information of the slip 1 is initially stored. The recorded information 21 is stored in the recorded information storage section 2, and its location is stored in the recorded information management section 3.
It is indicated by the storage information location 32 and identified by the storage information ID. Postscript information ID data 33, postscript position instruction data 34
, additional type data 35. The rewriting target data length 36 is
Since the stored information has not been rewritten, it is in an unfilled state.

FIG. 2 shows the state of the recorded information storage section and the recorded information management section when the remittance destination is rewritten in the A slip 1 of FIG. 1. In the recorded information storage unit 2, the changed and additionally recorded information 22 is indicated by the newly added stored information location 42, and is identified by the stored information ID data 41. The newly provided storage information ID is added to the already provided additional information ID data 33.
The same content as the data 41 is written, and the relative address from the beginning of the recorded information 21 is written in the additional writing position instruction data 34.
Type information is written in the additional write type data 35, and the data length to be rewritten in the recorded information 21 is written in the rewrite target data length 36, respectively. In this embodiment, the relationship between the append type information for rewriting and the data length to be rewritten is shown in Figure 3, but the content of the type information does not need to be limited to this example, and the content of the process can be identified. It's fine as long as it's information.

FIG. 4 is a flowchart showing the operation of the recorded information restoration process. In this flowchart, the processing of block number 100 causes the screen to be displayed in the order in which the permutations have been made, so that the permutation history can be visually shown.

According to this embodiment, there is an effect that part of the recorded data can be corrected without correcting the recorded contents of the A slip 1 recorded first. Furthermore, when restoring and displaying, the originally recorded content is displayed and then the rewritten state is displayed, so there is an effect that the progress of rewriting can be visually grasped.

The present invention relates to a method for reusing contents recorded on a magnetic card or a corresponding information recording medium such as a computer memory, and its hardware environment is shown in FIG.
As shown in FIG.

FIG. 5 shows a stand-alone card handling device, and FIG. 6 shows an information network type embodiment.

FIG. 6 shows a specific example of a cash handling machine.

In particular, FIG. 6 shows a case where a part of the information on the card is shared by the memory within the computer 112.

〔Effect of the invention〕

According to the present invention, it is possible to record the rewriting history of additions and modifications of stored information on an information storage medium, and the progress of rewriting can be visually displayed on the screen, so that the progress of additions and modifications of information can be recorded. It becomes possible to know easily.

Further, according to the present invention, even if a write-only nonvolatile storage medium that cannot be rewritten is used, rewriting can be performed in practice.
