Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a hybrid card reader / writer for recording or reproducing information on a hybrid card having different types of recording sections.

[0002]

2. Description of the Related Art In recent years, many optical information recording / reproducing apparatuses using a recording medium such as an optical file and a compact disc have been proposed. However, they are more portable than these recording media and have a larger size. Attention has been paid to a large-capacity card-shaped optical information recording medium (hereinafter referred to as an optical card).
The advantages of the optical card are that the storage capacity is as large as several megabytes, the copying is easy, and the cost is low. Further, the optical card is a write-once recording medium and cannot be falsified because information once recorded cannot be rewritten, and is a highly reliable recording medium. Furthermore, it is a small and light credit card size, large-capacity recording medium that is easy to carry, and large demand is expected.

An optical card is a medium for recording or reproducing information by literally irradiating light onto the optical card. The recorded information is reproduced by reciprocally moving the minutely focused light spot on the optical card, and the information is recorded as an optically detectable recording pit row by modulating the light spot according to the recorded information. . At this time, techniques for accurately recording information in a predetermined area include auto-focusing (hereinafter, referred to as AF) control and auto-tracking (hereinafter, referred to as AT) control. The AT control controls the light spot position in a direction orthogonal to the scanning direction in the optical card surface. The AF control controls the light spot position in a direction perpendicular to the optical card surface.
Of course, both controls are necessary even during reproduction.

[0004] In recent years, IC cards having excellent security characteristics have been receiving attention. It is well known that IC cards include a contact type and a non-contact type. Non-contact type IC cards use electromagnetic waves as a medium for transmitting information between the IC card and the recording / reproducing device. That is, this is a method in which coils are opposed to each other and information is transmitted using an induction electromagnetic field as a transmission medium. On the other hand, non-contact IC cards include a contact type (several mm), a proximity type (several tens of cm), and a remote type (several meters) depending on the communication distance, and are used depending on the application. In particular, the contact-type non-contact IC card requires less magnetic field strength for communication, so the card can be made thinner, and there is little possibility of interference with others, so the reliability and security are high, and it can be used for other electrical systems. There is an advantage that the influence of is small. In general, the storage capacity of an IC card cannot be increased due to physical and cost limitations, and is about several hundred bytes to several kilobytes.

Therefore, a hybrid card provided with a close contact type non-contact IC memory unit and an optical recording unit which combines the advantages of both cards and a hybrid card reader / writer for recording and reproducing information on the hybrid card have been proposed. I have. FIGS. 13 (a) and 13 (b) show a hybrid in which the IC memory section, the antenna coil, and the optical recording section of the optical card of the close contact type non-contact IC card coexist on one card-shaped medium. It is an external view which shows a card. FIG. 13A shows the non-contact IC memory unit side (the front side) of the hybrid card, and FIG. 13B shows the optical recording unit side (the back side). First, in FIG. 13A, reference numeral 100 denotes a hybrid card. Also, 101
Denotes an IC memory unit including a CPU, a memory, and a power supply unit;
Denotes an antenna coil unit, and the antenna coil unit 102 is connected to the IC memory unit 101. IC memory unit 1
01 and the antenna coil 102 are mounted by lamination.

Next, the principle of recording / reproducing information in the IC memory unit 101 of the hybrid card 100 will be briefly described with reference to FIG. In FIG. 14, 10
1 is an IC memory unit, 102 is a hybrid card antenna coil, 120 is an IC memory unit antenna coil,
Reference numeral 121 denotes an IC memory unit reader / writer. Here, information is recorded by the number 10 applied to the antenna coil 120 according to a recording command from the IC memory unit reader / writer 121.
The magnetic field near the antenna coil is changed by the radio frequency current of 0 kHz, and the antenna coil 1 is changed by electromagnetic induction.
The same signal as the signal applied to 20 is induced in antenna coil 102 of hybrid card 100.

When a signal is induced, a write command and write information are identified in the IC memory unit 101 including a CPU, a memory, and a power supply circuit, and the information is stored in the memory. At the time of reproduction, the reproduction command of the IC memory unit reader / writer 121 is issued according to the same principle as at the time of recording.
Hybrid card 1 from 21 antenna coils 120
The information is transmitted to the antenna coil 102 of the data memory 00 and the information is read from the data memory area designated by the IC memory unit 101. The information is modulated by the oscillator of the IC memory unit 101, transmitted by electromagnetic induction from the antenna coil 102 to the antenna coil 120 of the IC memory unit reader / writer 121, and demodulated by the IC memory unit reader / writer 121 to become information. Although simple, the above is the principle of recording and reproducing information using electromagnetic induction.

In FIG. 13B, reference numeral 103 denotes an optical recording unit. FIG. 15 is a schematic plan view of such an optical recording unit 103. A large number of information tracks 2 and tracking tracks 4 are alternately arranged on the recording surface of the optical recording section 103. The optical recording unit 103 has a home position 3 serving as a reference position for accessing the information track 2.
Is provided. The information tracks 2 are arranged in order from 2-1 to 2-2, 2-3,. Further, as shown in FIG. 15, tracking tracks are arranged adjacent to the information tracks 2 such as 4-1 4-2, 4-3.
These tracking tracks are used as a guide for AT control for controlling a light spot so as not to deviate from a target information track during information recording and reproduction.

Such an AT control detects a deviation (AT error) of a light spot from an information track in an optical head and feeds the detected information back to a tracking actuator that drives an objective lens in a tracking direction. Done by That is, the objective lens is moved in the tracking direction (D
, The light spot is controlled so as not to deviate from the target information track. Also, when scanning a light spot on an information track during information reproduction,
AF control is performed on the objective lens in order to make the light beam into a spot of an appropriate size on the recording surface of the hybrid card (focusing). In such AF control, a deviation (AF error) of the light spot from the in-focus state in the optical head is detected, and this detection signal is fed back to a focus actuator that moves the objective lens along the optical axis direction. By moving the objective lens in the focusing direction, the light spot is controlled to focus on the recording layer of the hybrid card.

FIG. 16 is a diagram showing the configuration of a conventional hybrid card reader / writer for recording and reproducing information on and from such a hybrid card. The information recording medium is an optical recording unit 1
03 and a hybrid card 100 having an IC memory unit 101. Further, the recording / reproducing method of the IC memory unit 101 is the method itself described in the aforementioned recording / reproducing principle. In FIG. 16, reference numeral 104 denotes a hybrid card 1
00 is a card mounting table (hereinafter, referred to as a card holder) for mounting 00. The card holder 104 can move in a direction orthogonal to the track of the optical recording unit 103 of the hybrid card 100, and is configured so that a light spot can access a desired track of the optical recording unit 103 of the hybrid card 100. Reference numeral 120 denotes an antenna coil, and 121 denotes an IC memory unit reader / writer in the hybrid card reader / writer. An optical head 501 is driven to reciprocate in the track direction of the optical recording unit 103,
By this reciprocating drive, the light spot and the hybrid card 100 reciprocate relatively in the track direction, and the light spot scans the information track.
Reference numeral 502 denotes an optical recording / reproduction control unit.

Here, the hybrid card 100 faces downward so that the antenna coil 102 in the card faces the antenna coil 120 of the card holder 104, and faces upward so that the optical recording unit 103 faces the optical head 501. I have. In this state, the card 100 is conveyed in the direction of the arrow, and set at the abutting position of the card holder 104. As a result, information can be recorded and reproduced at all times in accordance with a recording and reproducing command from the IC memory section reader / writer 121. In addition, information recording / recording in the optical recording unit 103 is performed.
The same applies to reproduction, and information can always be recorded in the optical recording unit 103 or existing information can be reproduced by the optical head 501 according to a command from the optical recording / reproduction control unit 502. The recording / reproduction of the optical recording unit 103 is as described above. A major feature of the hybrid card reader / writer 122 is that each of the memory sections of the optical recording section 103 and the IC memory section 101 is provided with a separate reader / writer section, so that respective information can be accessed. Therefore, each memory unit of the IC memory unit 101 and the optical recording unit 103 takes advantage of their respective features, and relatively small-capacity information such as unique information of the hybrid card and a user password is recorded in the IC memory unit 101. The optical recording unit 103 records a large amount of information such as image information and history information.

[0012]

However, in the above-described conventional hybrid reader / writer, the IC memory unit 1 is used.
01 is provided in the card holder 104 for recording and reproducing information with respect to the
There were the following problems. When the antenna coil 120 is provided in the card holder 104, the card holder 104 becomes heavy, so that the seek speed of the optical recording unit 103 to the target track becomes slow, and the recording / reproducing throughput of the optical recording unit 103 becomes slow. In order to increase the seek speed, the current applied to the motor driving the card holder 104 may be increased, but the power consumption will increase accordingly. At the same time as recording and reproducing information to and from the optical recording unit 103, an IC
When information is recorded in the memory unit 101, the throughput is the same as that of a conventional optical card reader / writer, that is, a reader / writer only for the optical recording unit 103. However, IC
Electromagnetic induction when recording and reproducing information in the memory unit 101 affects AF control and AT control in which an objective lens is driven by a coil and a magnet provided in an actuator, and accurate recording and reproduction cannot be performed. . Therefore, if information is recorded and reproduced on the optical recording unit 103 before and after recording and reproducing information on the IC memory unit 101, the recording and reproduction time of the IC memory unit 101 is smaller than that of the conventional optical card reader / writer. However, the throughput is reduced. Even when an unsupported card or a card with a broken IC memory unit 101 is inserted into the hybrid card reader / writer, the card is conveyed to the card holder 104 and settled, so that error processing is delayed by this time and the usability deteriorates. Power is wasted.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a hybrid card reader / writer capable of reducing power consumption and improving throughput.

[0014]

An object of the present invention is to provide a hybrid card having an optical recording unit, an IC memory unit, and a communication antenna coil connected to the IC memory unit. A sensor for detecting insertion, a transport mechanism for introducing or ejecting the hybrid card, a card holder for setting the introduced card, an optical head unit for recording or reproducing information on the optical recording unit, and the IC memory unit I record or reproduce information in
A hybrid card reader / writer comprising a C memory unit reader / writer, an antenna coil for communicating with an antenna coil of the card is provided in the middle of a transport path for introducing or ejecting the hybrid card, and the card is inserted or ejected. This is achieved by a hybrid card reader / writer characterized in that information is recorded or reproduced in the IC memory unit by sometimes communicating between an antenna coil of the card and an antenna coil provided in the transport path.

FIG. 4 shows in detail the configuration of the IC memory section 101, the antenna coil 102 of the hybrid card 100, and the reader / writer side for exchanging information without contact therewith. In FIG. 4, first, the hybrid card 10
0 is provided with an IC memory unit 101 and an antenna coil 102. The IC memory unit 101 controls each unit.
The PU 410 includes a detection rectifier circuit 406 that rectifies a signal from the antenna coil 102. The detection and rectification circuit 406 is provided between the reader / writer 122 and the antenna coil 12.
The modulated high-frequency signal transmitted through the first and second rectifiers 0 and 102 is rectified, and the rectified DC voltage is supplied to each unit in the IC memory unit 101 as a power supply.

On the other hand, on the hybrid reader / writer 122 side, an antenna coil 120 electromagnetically coupled to the antenna coil 102 in the card 100 and an IC connected to the antenna coil 120 are connected.
A memory reader / writer 121 is provided. The IC memory section reader / writer 121 includes an oscillation circuit (OSC) 403 that generates a high-frequency signal of a constant frequency, a transmission circuit 402 that modulates the high-frequency signal of the oscillation circuit 403 with data from the CPU 106, and outputs the signal as a high-frequency modulation signal.

Next, the specific operation of this embodiment will be described with reference to the flowchart of FIG. In FIG. 5, first, when the hybrid card 100 is inserted from the insertion slot 126, the insertion of the hybrid card 100 is detected by the reflection type optical sensor 127 (S501).
The CPU 106 recognizes the insertion of the card 100 based on the detection signal of the optical sensor 127 and issues an instruction to the transport motor drive circuit 124 to drive the motor 125 to introduce the hybrid card 100 into the apparatus. When the motor 125 is driven, the card 100 is transported by the lower rollers 129a and 129b and the upper rollers 130a and 130b.

3). Here, due to the positional relationship between the antenna coil 120 and the antenna coil 102 in the hybrid card 100, the electromagnetic coupling state of both coils has a relationship as shown in FIG. Becomes possible. That is, the reflection type optical sensor 128a is disposed at a predetermined position M where the degree of coupling A is equal to or higher than the predetermined coupling degree A. C
When detecting the hybrid card 100 based on the detection signal of the reflection type optical sensor 128a, the PU 106 starts recording / reproducing information to / from the IC memory unit 101 (S50).
4).

Here, the recording and reproduction of information in the IC memory unit 101 will be described in detail with reference to FIGS. When data is transmitted from the hybrid reader / writer 122 to the hybrid card 100 (recording), data from the host computer 123 is transferred to the hybrid reader / writer 122, processed by the CPU 106, and transmitted to the transmission circuit 402 in the IC unit reader / writer 121. Can be In the transmission circuit 402, a high-frequency signal having a constant amplitude is supplied as a carrier from the oscillation circuit 403, and the carrier is modulated with data to output a modulated high-frequency signal. In this case, any modulation method may be used as long as it has a constant amplitude such as frequency modulation or phase modulation. The modulated high-frequency signal output from the transmission circuit 402 is supplied to the antenna coil 120 via the driver 401.

On the other hand, in the hybrid card 100, the antenna coil 120 of the hybrid reader / writer 122
The modulated high-frequency signal is transmitted to the antenna coil 102 by electromagnetic coupling between the antenna coil 102 of the card 100 and
It is supplied to the IC memory unit 101. The modulated high-frequency signal is rectified by the detection and rectification circuit 406 and supplied to the power supply circuit 407 to generate a predetermined power supply voltage required for each part of the hybrid card 100. The antenna coil 102
Is also supplied to the receiving circuit 408, where the data is demodulated and supplied to the CPU 410. The CPU 410 processes the supplied data and writes it to a memory (not shown).

When data is transmitted from the hybrid card 100 to the hybrid reader / writer 122 (reproduction), the hybrid reader / writer 122 outputs a non-modulated high-frequency signal with a constant amplitude from the transmission circuit 402 to the driver 401 and the coil 120. , 102 to the hybrid card 100. In the hybrid card 100, the high-frequency signal is rectified by the detection and rectification circuit 406 and supplied to the power supply circuit 407 in the same manner as described above, and a predetermined power supply voltage is generated. On the other hand, in the hybrid card 100, data read from a memory (not shown) is processed by the CPU 410 and supplied to the transmission circuit 409. The transmission circuit 409 is composed of, for example, an additional resistor and a switch.
This switch turns on and off according to the “0” bit.
When the switch of the transmission circuit 409 is turned on and off, the load on the coil 120 changes, so that the amplitude of the high-frequency current flowing through the coil 120 changes. That is, the high-frequency current is amplitude-modulated by data supplied from the CPU 410 of the hybrid card 100 to the transmission circuit 409. This high-frequency current is detected by the current detecting means 405,
The data is obtained by demodulation by the receiving circuit 404. This data is processed by the CPU 106 and the host computer 1
23.

In this way, the hybrid card 100
When the hybrid card is detected by the reflective optical sensor 128b arranged at the predetermined position N (S505), the CP
U106 ends the recording / reproduction of information with respect to the IC memory unit 101 (S506). Here, the reflection type optical sensor 1
The predetermined position N where 28b is arranged is the antenna coil 12
0 and the antenna coil 10 in the hybrid card 100
The position where the degree of electromagnetic coupling with No. 2 is equal to or less than the predetermined degree of coupling A shown in FIG. Therefore, assuming that the transport speed is V and the distance from M to N is L, the time t during which recording and reproduction can be performed is t =
It is represented by L / V. Normally, the transfer speed is set to the IC memory unit 10
1 is sufficiently slower than the recording / reproducing speed, so that the recording / reproducing of information can be sufficiently performed. Within this time t, the IC memory unit 1
By performing the recording and reproduction of 01, time is not wasted and the throughput can be improved. In S504, I
When recording and reproducing information in the C memory unit 101, if the recording and reproduction cannot be performed normally, the CPU 106 performs an error process such as displaying an error message or controlling the transport mechanism to eject the card 100. That is, when another card that is not compatible with the system is inserted, or when the IC memory unit 101 is out of order, error processing is performed during the transport of the card. Thereafter, the hybrid card 100 is further conveyed into the device and settled at the abutting position of the card holder 104 (S507). As a result, information can be recorded / reproduced in the optical recording unit 103, and the optical head accesses a desired track to record or reproduce information in / from the optical recording unit 103 (S508).

As described above, in the present embodiment, since the antenna coil 120 on the reader / writer 122 side is arranged in the middle of the card transport path, the weight of the card holder 104 can be reduced, and the power consumption can be reduced. Throughput can be improved. In addition, since information is recorded / reproduced in / from the IC memory unit 101 while the hybrid card 100 is being conveyed, the throughput can be improved. AF control and A
There is no influence on the T control, and highly reliable recording and reproduction can be performed on the optical recording unit 103. Further, when an unsupported hybrid card is inserted or the IC memory unit 101 is out of order, error processing such as issuing an error message or ejecting the card can be started immediately from the middle of the card transport. Yes, it is convenient in terms of usability.

In the first embodiment, the IC memory unit 10 is operated based on the detection signals of the reflection type optical sensors 128a and 128b.
Recording / reproduction of information to / from the optical disc 1 was performed, but a position sensor such as a rotary encoder was attached to the lower roller. You may make it start. Further, the recording / reproducing operation may be started after a predetermined time from the detection of the card by the reflection type optical sensor 127, and the recording / reproducing operation may be ended after the predetermined time. Further, although the antenna coil 120 is disposed on the lower surface side of the hybrid card in the transport path, it may be disposed on the upper surface side or at any position as long as a predetermined electromagnetic coupling degree can be obtained. Further, recording / reproducing was performed on the IC memory unit 101 at the time of introduction when the hybrid card was inserted.

FIG. 7 is a diagram showing the configuration of the second embodiment of the present invention. In the present embodiment, the hybrid card 100 shown in FIG. 13 is used. However, the method of the IC unit is different from that of the first embodiment, and a proximity non-contact IC having a communication distance of several tens cm is used. Further, in the present embodiment, as shown in FIG.
The antenna coil 120 that communicates with the antenna 02 is disposed obliquely below the card transport path.
