DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention provides data transfer/transfer for portable storage media.
The present invention relates to a processing system that performs writing, and particularly to a non-contact portable storage medium processing system that sends and receives data to and from a portable storage medium located within the communication range of a main device.

(Middle) Conventional Technology Automatic ticket gates installed at ticket gates at stations and the like are known as processing systems that perform data read/write processing on portable storage media. Generally, in conventional automatic ticket gates, traffic data is magnetically recorded on magnetic tickets such as commuter passes and tickets, and data is read/written on the magnetic ticket inserted through the insertion slot of the automatic ticket gate. I was doing it. However, the work of inserting magnetic tickets such as commuter passes and tickets into automatic ticket gates is complicated for users, and it takes a long time to process the ticket gates compared to when passing through a manned ticket gate. As a result, the improvement of

Therefore, for portable storage media located within the communication range of the communication unit provided in the main device! A non-contact portable storage medium processing system that transmits and receives data using magnetic coupling or the like has been proposed. According to this processing system, when passing through a main device such as an automatic ticket gate, the user only needs to present a portable storage medium within a predetermined communication range. It is possible to improve the utilization rate and save labor at ticket gates.

(C) Problems to be Solved by the Invention However, in the above-mentioned non-contact portable storage medium processing system, the user presents the portable storage medium to the communication range of the main device, and thereby the user locates the portable storage medium within the communication range of the main device. Because data was exchanged between the portable storage medium and the main device, the portable storage medium may be out of the communication range of the main device as the user passes by before the read/write process is completed. It may move to . Generally, when writing data to a portable storage medium, new data is written to the data storage area of the portable storage medium that stored data from the previous writing process, but during the data writing process When a portable storage medium moves out of the communication range, data can only be rewritten halfway into the data storage area, and even if you later try to recover the data storage area, the previous rewriting process for the data that caused the error will not work. There was a problem in that the contents written during the rewriting process could not be reproduced, making it impossible to recover the data, and making the portable storage medium unusable.

An object of the present invention is to provide a plurality of data storage areas in a portable storage medium, and write data to the plurality of data storage areas in order, so that the data writing process currently being executed can be The contents of the data written in the previous write process are always retained, and the portable storage medium moves out of the communication range during the data write process, which causes an error in the write process. Even in the event of an error, it is possible to reproduce the contents of the data written in the writing process before the error occurred, and to easily recover the data storage area so that the portable storage medium can be used continuously. An object of the present invention is to provide a contact type portable storage medium processing system.

(d) Means for Solving the Problems The non-contact portable storage medium storage processing system of the present invention has the following features:
In a processing system comprising a main device and a portable storage medium that sends and receives data to and from the main device within the communication range of the main device, data is sent to and received from the main device by the portable storage medium. A plurality of data storage areas for storing data are provided, and the main device is provided with data rewriting means for rewriting data to a data storage area other than the data storage area in which the latest data is stored. Features.

(e) Effect In this invention, the portable storage medium is provided with a plurality of data storage areas, and from among the plurality of data storage areas, an area other than the area in which the latest data is stored is accessed from the main device. The sent update data is written. Therefore, the update data sent from the main device is written to each of the multiple data storage areas one by one, and while the data write process is being executed, the data written in the previous write process is Retained in data storage. Therefore, even if an error occurs during the currently executing write process, it is possible to refer to the data written by the previous write process and rewrite the data related to the write process that caused the error. .

(D Embodiment FIGS. 2(A) to 2(C) are respectively plan views of automatic ticket gates in which the processing system according to the embodiment of this invention is used;
- They are a side view and a front view in the X direction.

The automatic ticket gate @1 has two unit bodies 100a.

100b as a pair! A ticket passageway is formed between the two unit bodies 100a and 100b. Note that the unit main body 101b constitutes one of the other adjacent automatic ticket gates. One unit body 10
0a is provided with an antenna 21a, a display 22a, and traffic blocking layers 23a (f not shown) and 24a. Further, the unit body 100b is provided with an antenna 21b, a display 22b, and traffic blocking layers 23b and 24b. The ticket gate passage formed by the unit bodies 100a and 100b is indicated by the arrow A in FIG.
When passing in the direction of arrow B, the antenna 21a, display 22a and passage blocking layers 24a and 24b are used, and on the other hand, when passing in the direction of arrow B, the antenna 21b, display 22b and passage blocking layers 23a and 23b are used.

The antenna 21 (21a, 2lb) constitutes a resonant circuit that resonates with a signal of a specific frequency by combining with a resonant capacitor (not shown), and enables communication by electromagnetic coupling between the unit main body 100 and an IC card to be described later. It has become. Furthermore, the resonance characteristics of this electromagnetic coupling are utilized to supply power to the IC card.

A plurality of sensors 25 to 34 are provided on the side surfaces of the unit bodies 100a and 100b facing the ticket gate passageway to detect the state of passage of people and objects. These sensors 25 to 34 are light transmitters 25aa to 3 provided in the unit main body 100a.
4a (not shown) and light receivers 25b to 34b provided on the unit main body 100b. Of these, the sensors 31 to 34 are connected to the unit main bodies 100a and 10.
The handrail-like frames 41a and 41b protrude from the upper surface of 0b. The frames 41a and 41b are provided to detect the height of objects passing through the automatic ticket gate. That is, the eight sensors 27, 28,
32. 33 are all turned on and then all of them are turned off to count one adult, and sensor 27 +
It is determined that the dwarf or baggage has passed by the Mikaon/'off action of 28.

In the above configuration, the antennas 21a and 21b provided on the upper surfaces of 100a and 100b form a communication range in a predetermined space above them. When a user passes through an automatic ticket gate, he or she places his or her IC card (portable storage medium) within the communication range of the antenna 2ia21b, and automatically connects the IC card, which is a commuter pass, coupon ticket, or prepaid card. Data is sent and received to and from the ticket gate. Ticket processing is performed at an automatic ticket gate using the traffic data obtained through this transmission and reception, and the results are displayed on the displays 22a and 22b.

Figure i (A)s and (B) show the automatic ticket gate and I
It is a block diagram of the control part of C card.

In the automatic ticket gate 1, the CPU 51 executes ticket gate processing according to a program written in advance in the RO to 150. At this time, a predetermined memory area of the RAM 53 is used as a working area. Display control section 58
Displays 22a and 22b provided on the upper surfaces of the unit bodies 100a and 100b are connected to the unit bodies 100a and 100b, and screen display control for these displays 22a and 22b is performed. The door opening/closing control circuit 59 performs opening/closing control on the passage blocking layers 23,24. In addition, the read/write control circuit 60
The above-mentioned IC card (commuter pass, commuter pass,
A sensor control circuit 61, which communicates data with coupons and prepaid cards, detects objects using sensors 25-34. These control circuits 58-61 are connected to the pass lines via interface circuits 54-57.

The CPU 9 provided in the portable recording medium 2 is a ROM IO
The main device 1 executes processing operations according to a program written in advance, and transmits and receives data to and from the main device 1 via the transmission and reception control circuit 13. At this time, RAMII is used as a working area. In addition, data that is generated during processing and should be stored is stored in EEPROMI 2.
is stored in This is because the IC card does not have its own power source and receives power from the main device 1 through electromagnetic coupling, and data necessary for later processing is stored in the EEPROMI 2. The IC card 2 is equipped with a power supply circuit 15 in order to receive power supply from the main device 1, and after receiving the voltage generated in the resonant circuit by magnetic coupling from the transmission/reception control circuit 13 and adjusting the voltage, the IC card 2 is sent to the CPU.
Supply to 9. Right, CPU9, ROM10 and RA
rviL1↓ is generally composed of a one-chip microcomputer.

Figure 3 shows the EEFR that constitutes the control section of the IC card.
This is a memory map of OM.

As shown in the figure, EEPROMI 2 stores fixed data and variable data. The fixed data includes data written in the issuing company when the IC card 2 is issued, such as the electric railway code, the issued amount, and the issued date. On the other hand, variable data is updated by data updated every time a write process is performed, such as balance, number of rides, boarding station, boarding time, and number of writes. This variable data is the data transmitted from the automatic ticket gate 1i1. EEPR
In OMI2, the variable data storage area in which this variable data is stored is divided into two areas, area A and area B. Area A and area B have exactly the same configuration, and each stores write data transmitted from the automatic ticket gate 1.

Further, in the write process, write data is stored in either area A or area B according to instructions from the mobile ticket gate 1.

FIG. 4 and FIG. 5 are flowcharts showing the processing procedure of the automatic ticket gate and the control section of the IC card.

When the IC card 2 is presented within the communication range of the antenna 21 of the automatic ticket gate 1, the antenna 21 of the automatic ticket gate 1 and the IC
A voltage is generated across the resonant circuit due to the magnetic coupling between the IC card 2 and the antenna 14, and the CPU 9 of the IC card 2 starts the operation shown in FIG. 5 using this voltage as a power source. Incidentally, magnetic coupling supplies a t source to the IC card and simultaneously realizes signal transmission and reception. That is, I
The C card 2 transmits response data indicating that it is located within the communication range to the automatic ticket gate 111 (n2
1), C of automatic ticket gate 1 that received this response data
The PU 51 learns that the IC card 2 is within the communication range and sends a read command to the IC card (
nl, n2), upon receiving the read command sent from the automatic ticket gate ill, the CPU 9 of the IC card 2 reads the EEPROM.
The data stored in I2 (see FIG. 3) is transmitted to automatic ticket gate 1 (n22, n23). The automatic ticket gate 1 that receives the data from the IC card 2 determines whether the data is good or bad, and saves variable data in the area A or It is determined which data in area B is the latest data (n4, n5). This determination is made based on the number of writes stored at the bottom of each of area A and area B. That is, the area with the larger number of writes is the area that stores the latest data. Now, if the number of writes in area A is larger, write data to area B (n6), and if the number of writes to area B is larger, write to area A. Instruct (n7) to transmit update data.

When the data writing process to either area A or area B is successfully completed in this way, the passage blocking field 23.2
4 is opened and the user is allowed to pass (n8, n9).

If the data transmitted from the IC card is defective in n4, or if the writing process is interrupted midway in n8, the traffic blocking area 23 and 24 are closed until the user leaves the aisle (n10, n11). If the write process is not performed normally, such as when the user moves the IC card 2 out of the communication range before the write process is completed, the area A or B in the EEPROMI 2 may be changed. It turns out that the update data has been written halfway to one of them. Now, if the write process to area B is interrupted, the previous latest data remains stored in area A of the IC card. Therefore, when the IC card is presented within the communication range again, the automatic ticket gate 1 reads the data stored in area A as the latest data, performs the ticket gate processing based on this, and performs the ticket gate processing based on this data. The updated data is sent again by specifying area B. Therefore, even if an error occurs during the write process, the previous latest data is retained, and the data can be easily restored.

(8) Effects of the Invention According to this invention, data writing processing is performed to an area other than the area where the previous latest data is stored, so even if the writing process is interrupted, the previous latest data Since the data is retained in another storage area, the data can be easily restored later using the latest data, and the portable storage medium can be used continuously.
