Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an optical/IC card, and in particular to an optical/IC card having an IC module having a control section and a storage section and an optical memory.
It's about cards.

(Prior art) A card with a built-in IC module is called an IC card.In particular, an IC card with a control unit and a storage unit is itself a small information processing device, so it is widely used for credit cards, etc. has been done.

Optical cards, which use laser beams, halogen lamps, etc., to read holes with m-shaped holes or precisely printed bit patterns and convert them into electrical signals, are more restricted than IC cards in that the recorded information cannot be rewritten. However, because of its large storage capacity, it is expected to be used for publishing and other purposes.

Furthermore, an information carrier card in which an optical memory and an IC memory are incorporated into one card is disclosed in Japanese Patent Application Laid-open No. 103287/1987. According to this, information that does not require rewriting is recorded in an optical memory capable of high-density recording, and information that requires rewriting is recorded in a rewritable IC memory.

(Problems to be solved by the invention) An optical/IC card that combines an IC card and an optical card can be used to change fortunes, but has an IC memory that does not have sufficient storage capacity, and an IC memory that has sufficient storage capacity, but does not have sufficient storage capacity. By using a non-rewritable optical memory and mutually compensating for the weaknesses of one with the strengths of the other, it is possible to process g-density information.

In such an optical/IC card, in order to realize high-level information processing, it is necessary that the codes of information recorded in the IC memory and the optical memory be compatible with each other during the information processing process. In addition, during the process of manufacturing many optical/IC cards of the same type, information that is common to all cards and does not require rewriting should be recorded in advance in the optical memory section of all cards. It is preferable to keep it. It is convenient to record information unique to each card for each card after the optical/IC card is manufactured.

(Means for solving the problems) This invention was made in view of the above points, and
In an optical/IC card equipped with an ICE-joule and an optical memory having a storage part and a storage part, the storage part records unique information existing for each card, and the optical memory stores information related to all of a plurality of cards of the same type. The unique information and the common information are configured with mutually compatible codes, and the unique information and the common information are processed by the signal processing system of tli-. The present invention provides an optical/IC card that is characterized by the fact that it enables the following.

(Operations and Effects of the Invention) According to the present invention, a rewritable IC memory and an optical memory which cannot be rewritable but have a large storage capacity are provided, and information that is common to many optical/IC cards is provided. Since the card can be uniformly recorded in the optical memory during the manufacturing process of the cards, optical/IC cards can be manufactured efficiently and can contribute to cost reduction. Furthermore, regarding the unique information that exists for each card, it is impossible to store all of it during the card manufacturing process because some information is undefined. Therefore, such unique information can be recorded individually for each card after the card is manufactured. It goes without saying that even if it is unique information, information that will not be rewritten in the future can be recorded in the optical memory.

According to this invention, the unique information and the common information are expressed using codes that are compatible with each other, so that a single optical/IC card reader/writer can process both the unique information and the common information. Advanced information processing can be achieved. More specifically, information recorded in the optical memory of the Jinjyaku can be quickly accessed using an index recorded in the IC module, or secrets stored in the IC module can be accessed using a password recorded in the IC module. 11! Accessing data and information with read restrictions in optical memory, etc. I am good at carrying out principles.

(Example) As shown in FIG. 1, an optical/IC card 1 includes an optical stripe 2 which is an optical memory that records a large amount of fixed information, and an IC module that records additional information. It can be used as a specification sheet, but it will be explained in detail below, taking as an example the case where it is applied to a car! I'll do it.

The optical stripe 2 can record 400 kilobytes to 2 megabytes of information, but since it cannot be replaced, it mainly records fixed information. The parts used in products are generally unified into different types, and the same parts are used for the same type, so when creating a card, the parts information for each type of performance is set to the common information. Record (mask). If different parts are used within the model,
Cards are created by grouping common parts and recording their common information. Also, since parts may change, cards are updated and created for each question.

The IC module 3 is composed of a microprocessor (MPU) and an IC memory, for example, a 128 kilobyte EEPROM. In this example, the 16 kilobyte storage capacity includes an information registration area (storage unit) and an information control program area. The latter together with MPtJ forms the control part of the Ic card. The υ control includes security measures, such as remembering and checking passwords. The storage unit of the IC module 3 stores unique information for each vehicle, that is,
The serial number, user information, maintenance inspection history information, optional parts information, repair parts replacement information, etc. are recorded.

Figure 2 shows the usage status of the optical 10 card. The optical/IC card reader/writer 6 has an optical/IC card 1 inserted inside the lower part, and the IC module 3 has a small handy terminal 9 for reading the optical/IC card. Only the sensor is equipped. The optical/IC card reader/writer 6 or the handy terminal 9 is connected to a personal computer 10 or a host computer 11 at the center for information processing.

The IC sensor 7 may be any type of contact type terminal (contactor), non-contact type optical sensor, or magnetic sensor.

FIG. 3 shows a more detailed configuration of the optical/IC card reader/writer 6. In the figure, when the optical/IC card 1 is inserted from the insertion slot of the reader/writer, the card fixing roller 1
3.13, it is fixed at a predetermined position and positioned correctly facing the IC sensor 7. On the underside of the optical/IC card, there is an optical/IC card stage 1 that slides along the card.
4 is placed. This card stage can be reciprocated in the direction of the arrow in the figure by a stage g movement motor 16 which is driven by a stage movement motor drive circuit 15. This direction of movement is perpendicular to the optical stripe 2. The card stage 14 holds an optical sensor 8 that moves in a direction perpendicular to the plane of the paper, that is, in the direction of the optical stripe. This optical sensor 8 is driven by a linear motor 18 driven by a linear motor drive circuit 17. The Ic sensor 7 is connected to an IC memory reader/writer circuit 20. On the other hand, the optical sensor 8 receives the light from the semiconductor laser drive 22 and sends the output to the preamplifier 2.
3 to the optical memory reading circuit 24 and the linear motor drive circuit 17, which detect the recording addresses of the optical memory recorded information and the read information, respectively. A microprocessor 26 and a memory section 27 including ROM and RAM 111 controls the circuits 15, 17, 20 and 24 and processes the signals from these circuits. The interface 28 is for exchanging information with the outside.

FIG. 4 is a flow diagram showing the procedure for issuing an optical/IC card. In step 110, the above-mentioned common information is recorded (masked) on the optical stripe 2. This is typically done during card manufacture. Next, in step 120, the above-mentioned unique information is recorded, which is usually recorded in the IC memory by the card issuing entity by the card issuing machine after the card is manufactured. Finally, in step 130, the computer 10
Other information, such as car model in common information,
Information such as the model and year is recorded in the IC memory, but this
This is usually done when the machine is sold and the user decides.

FIG. 5 shows the optical stripe 2 in the optical IC card and the contents of information recorded in the IC memory. The common information recorded on the optical stripe 2 and the unique information recorded on the IC memory include codes that are compatible with each other.

As shown by the arrow in Fig. 5, the optical stripe and IC
The information recorded in both memories, such as vehicle type, model/year, and group name (group name for grouping parts by mounting specifications), is made to correspond to each other, and the optical string is Codes that are compatible with each other are used so that the part number on the live part corresponds to the used part number (the number of the part mounted on the vehicle) on the tC memory. The same bibliographical items such as car model, model/year, and group name are recorded twice in the IC memory as well as the optical stripe. This is to ensure that the The specification part number is recorded in the tC memory, but this is the part number recorded on the optical stripe (the same car model may have multiple part numbers, as different parts may be used in the same location). ), it indicates the number of the part actually used in the vehicle, and the amount of information is not so large that it can be recorded in an IC memory.

The specifications in the optical stripe are recorded only on the optical stripe because the amount of information is enormous. Optical stripe and IC
Each piece of information recorded in the memory is read as mutually corresponding codes by the IC sensor 7 and optical sensor 8 in the optical/IG reader/writer 6, and is collated and processed by the personal computer 10. There are a large number of Hikari Strive specification articles, so even if you access them directly, it will take time and it will be difficult to extract the necessary information.However, it is easy and accurate to specify the car model, model year, part name, part number, etc. from outside. You can read it.

FIG. 6 shows an example of information processing using an optical/IC card, in which parts search, user management, 'II
! @1 shows a 70-chart when processing each task of management.

As shown in Figure 5, the detailed specifications of parts are recorded in the optical stripe as common information for each car model, so in order to perform a parts search, first the car model,
The model year, etc. is read from the IC memory, and based on this, the corresponding car model and year are accessed to the optical stripe to obtain the specifications of the corresponding parts. This will be explained in detail below with reference to the flowchart shown in FIG.

In step 200, the optical/IC card 1 is inserted into the optical/IC card reader/writer 6, and commands are input from the keyboard of the personal computer 10. In step 202, it is determined whether this command is a parts search command. Here, No
If so, in step 203, a menu is displayed on the screen of the display device of the personal computer 10 to select another command, that is, user management 1 for reading user information, or maintenance repair management for writing/reading maintenance repair management. is displayed.

If YES in step 202, a parts search program is entered. In step 206, it is determined whether a search can be performed by part name. If YES here, step 2
10 for PC 10! When the part name is input from the first board, in step 211, if it is determined No in step 206, that is, it is determined that it is not possible to search for parts by part name, the group name of the vehicle type is input from the keyboard of the personal computer 10 in step 213. At step 214, the vehicle model/year specific to the card is read from the IC memory via the IC sensor 7 of the optical/IC card reader/writer 6. Next, in step 215, the optical sensor of the optical/IC card reader/writer 6
Among the part names recorded on the optical stripe via step 8, the one corresponding to the car + 4/model year entered in step 214 is read, and in step 216 this is output to the computer 10, and in step 217 The corresponding parts are displayed as a list on the 10 display screen. In step 218, choose the part name you need from among these! Select by entering the number using 1all etc.

By step 211 or step 218, the car model, model year, and part name to be searched have been determined, so in step 220, the optical sensor of the optical/IC card reader/writer 6
8, the part number corresponding to both the above car model, model year and part name is read from the light stripe. This part number becomes a group of multiple parts when the part name is a superordinate concept or a wide concept, or when multiple parts can be used. Next, in step 221, the IC sensor 7 in the optical/IC card reader/writer 6 reads the number of the part actually installed in the vehicle from among the unique information recorded in the IC memory 5. In step 220, the part number read out in step 221 is compared with the part number read out from the part number group on the optical stripe to extract the matching number. According to this extracted number, the specifications of the corresponding part number are read from the optical stripe 1 in step 222. In step 223, this is output to the personal computer, and in step 224, the corresponding part specifications are displayed on the display screen of the personal computer, and this routine is ended.

By the procedure illustrated above, the title section in the optical stripe and IC memory (model, model year, part number, part name) is saved.
