Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called composite card which combines the functions of a contact type IC card and a non-contact type IC card with the functions of an optical card and a magnetic card. And an information recording / reproducing apparatus that performs at least one of the following.

[0002]

2. Description of the Related Art Conventionally, as a card-shaped recording medium, a magnetic card for recording and reproducing information using a magnetic stripe,
2. Description of the Related Art There are known an optical card that optically records and reproduces information using a laser beam, an IC card in which an IC chip is embedded in the card, and the like.

[0003] Although such cards are excellent in portability, they each have the following advantages and disadvantages. For example, for a magnetic card, the production cost is low and information can be read and written.However, since the storage capacity is as small as several tens of bytes, much information cannot be recorded. Although the storage capacity can store a large amount of information of several megabytes, the information cannot be rewritten, which limits its use. Furthermore, IC cards can be accessed at high speed, and moreover, information can be stored. Although secrecy is easy to maintain, it is advantageous in terms of security, but the unit price per unit recording capacity may be high.

Conventionally, in order to make use of the features of each of these cards and to compensate for their respective drawbacks, a compound card (hereinafter referred to as a hybrid card) combining the functions of an optical card and a magnetic card together with the function of an IC card has been proposed. ) Is considered.

[0005] Recently, as an IC card,
External terminal (connector) of IC chip exposed on card
Non-contact type, which uses a principle such as electromagnetic induction or electrostatic coupling, in addition to a contact type IC card that transmits and receives data by physically contacting a contact on the information recording / reproducing device side An IC card has been put into practical use. As an information recording / reproducing apparatus capable of handling a hybrid card in which the functions of an optical card and a magnetic card are combined with such a contact type and non-contact type IC card function, the present applicant has The proposals described in Japanese Patent Application No. 9-298801 and Japanese Patent Application No. 9-300511 are considered.

That is, as an information recording / reproducing apparatus which can handle such a hybrid card, for example,
As shown in FIG. 7, a hybrid card 101 having an IC capable of inputting and outputting in a non-contact manner is placed thereon, and the hybrid card 101 is placed on a card mounting table 102 for reciprocating the hybrid card 101 in a linear direction. A coupling means 103 for providing a predetermined function wirelessly to a type IC is provided. As shown in FIG. 8, the coupling means 103 is provided with a coupling region 104 comprising a dielectric coupling region and an electrostatic coupling region. The module section 105 is divided into two parts, and only the coupling area 104 including the dielectric coupling area and the electrostatic coupling area is
2 and the module unit 105 is separately arranged at a position where the movement of the optical head 106 is not hindered. Further, as shown in FIG. The coupling means 103 to be provided is provided so as to be vertically movable by a vertically moving drive mechanism 107 disposed within a reciprocating movement range of the card mounting table 102, and the hybrid card is moved to a predetermined position with the movement of the card mounting table 102. The vertical drive mechanism 10
7, the coupling means 103 is lowered to a position above the hybrid card 101 so as to wirelessly provide a predetermined function to the non-contact type IC.

There is also a dissatisfaction that access to the non-contact type IC of the hybrid card 101 cannot be started until the device 1 is placed at a predetermined position on the card placing table 102.

[0008] Further, in the apparatus shown in FIG. 9, since it is necessary to move the non-contact type IC of the hybrid card to the position corresponding to the coupling means 103, it takes time to start access to the non-contact type IC, and In order to recognize the inserted card, the above operation or access to the information recorded in the optical recording unit of the hybrid card must be performed at least once, so that it takes time to recognize the card. However, there has been a complaint that the optical recording section and the IC section cannot be accessed simultaneously.

Next, the non-contact type I of the hybrid card 1
Access to C1b will be described. First, a non-contact type I of the hybrid card 1 is sent from a host computer (not shown).
When access execution to C1b is instructed, C (not shown)
The PU causes the communication module 21 to execute an activation process. In this case, as shown in FIG.
Range K of the hybrid card 1 to be moved with
Contactless IC1 of hybrid card 1 in all areas
b and the antenna 20 are in a coupling state enabling wireless communication, so that the activation processing by the communication module 21 immediately activates the non-contact type IC 1b of the hybrid card 1. .

After these activation processes, when the host computer issues a command / information to the contactless IC 1b of the hybrid card 1 from the host computer, the communication module 21 converts the command / information into a predetermined protocol, and converts this into a predetermined protocol.
To the non-contact type IC 1b of the hybrid card 1, and conversely, the non-contact type IC 1b of the hybrid card 1
When a response / information is issued from the
This is received by the communication module 21 via the antenna 20 and transmitted to the CPU, whereby recording / reproduction of information to / from the non-contact type IC 1b of the hybrid card 1 is executed.

The wireless communication between the communication module 21 and the non-contact type IC 1b via the antenna 20 is performed when the non-contact type IC 1b is mounted as the hybrid card 1 by card recognition. Since it is confirmed in advance, the optimal sequence can be executed quickly.

In addition, in the proximity type or proximity type non-contact type IC 1b, since the communication distance with the antenna 20 of the communication means can be increased, it is necessary to perform an operation of bringing the hybrid card 1 and the communication means close to a close contact position each time communication is performed. Therefore, the time until the start of access to the non-contact type IC 1b can be greatly reduced. Further, by increasing the communication distance between the non-contact type IC 1b and the communication means, the hybrid card 1 can be placed on the card placing table 2 and the card can be identified at the same time. It can be executed immediately upon insertion, and data stored in the memory of the non-contact type IC 1b such as an encryption key and a user authentication key can be received immediately, so that the apparatus speed can be further improved.

Other parts are the same as those in FIG. 1, and the same parts are denoted by the same reference numerals. In this way, the antenna 20 can be arranged in the dead space behind the optical head 18, so that space can be saved and the device can be downsized.

[0038]
