Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing system using an IC card, and particularly to a data processing device that transmits data to and from an IC card.

[Conventional technology]

In recent years, data processing systems using IC cards (hereinafter referred to as
(referred to as an IC card system) has been developed. IC
As is well known, the card itself has MPU and ROM.
, RAM, and other integrated circuit electronic circuits (hereinafter referred to as modules). The IC card system has a data processing device loaded with the above-mentioned IC card, and performs data processing by transmitting data between the data processing device and the IC card. This is what we do.

By the way, in the case of IC card systems, the International Organization for Standardization (ISO) is currently unifying standards regarding the positions of terminals provided on the card body and data processing protocols between modules and data processing devices. ing.

However, at present, there is no prospect of complete unification of the standards, and the reality is that there are two broad standards.

[Problem that the invention seeks to solve]

Under the above-mentioned situation, the user must select a device that meets the specifications of the IC card to be used. If this selection is incorrect, various problems may occur, such as destruction of the module, damage to the surface of the IC card, and damage to the contact bin provided on the device side for connection with the terminals.

This invention has been made to address the above-mentioned circumstances, and is a data processing device for IC cards that can reliably prevent damage to the module even when IC cards of different standards are loaded! The purpose is to provide.

[Means and effects for solving the problem] This invention focuses on the fact that the IC card of one of the two standards mentioned above is equipped with a magnetic recording section, and the other IC card does not have this. Then, by determining whether or not the loaded IC card has the above-mentioned magnetic recording section, it is determined whether or not this is a card that can be accessed by the data processing device, and it is determined that the IC card is accessible. It is configured so that only an IC card can be accessed.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a diagram showing the overall configuration of an IC card data processing device according to an embodiment, and FIG. 2 is a flowchart for explaining its operation. FIGS. 3 and 4 are diagrams showing the mechanical configuration of a card loading section in an embodiment of the device.

First, the configuration and operation of FIG. 1 will be explained with reference to FIG. 2. The device shown in FIG. 1 is of a type that can access an IC card that has a magnetic recording section.

In FIG. 1, 100 is an IC card data processing device, and 200 is an IC card.

In the figure, an IC card 200 having a striped magnetic recording section 201 is shown. This IC card 200
202 is a terminal for electrically connecting the module built into the card body and the device 100.

By loading the IC card 200 into the card loading section 101 provided in the device 100, data transmission between the IC card 200 and the data processing/control section 102 of the device 100 becomes possible. The details of the card loading section 101 are shown in FIGS. 3 and 4.
As will be explained with reference to the drawings, an automatic slide method is used as the card loading method. That is, when the user inserts the IC card 200 into the card insertion slot, the r
The c-card 200 is guided into the card loading section 101,
The card is set at a predetermined card loading position. On the other hand, when taking out the IC card 200, the IC card 20θ is automatically guided to the outside of the card loading section 101 through the card insertion slot.

Now, when the IC card 200 is inserted into the card insertion slot, the microswitch 103 is turned on (or turned off). This allows the data processing/control unit 102 to detect that insertion of the IC card 200 has started. This process progresses to step S1 in FIG.

Note that the data processing/control unit 102 has a CPU, performs various data processing and operation control, and is the core of the apparatus 100.

When the data processing/control unit 102 detects insertion of the IC card 2θ0, it turns on the card drive unit 104. As a result, the IC card 200 is automatically guided into the card loading section 101 while sliding. At the same time, the data processing/control unit 102 turns on the magnetic reading unit 105 disposed in the card loading unit 101 in step S2. As a result, the data processing/control unit 102
In parallel with the conveyance of 0, the read output of the magnetic recording section 201 can be obtained.

When the data processing/control unit 102 turns on the magnetic reading unit 105, the process moves to step S3 in FIG. 2, and the level of the reading output is set to L. and the reference value LR. Then, in the next step S4, the above comparison result is determined and the reading output level L is determined. is larger than the reference value LB, step Ss
If it is smaller, move to step S.

In step S5, the read output is decoded. This decoding result Dx is compared with the reference data DR in the next step S6. This matching result is judged in the next step S7, and if both data match, the next step S8
If they do not match, the process moves to step S- above.

Step S8 is a step of accessing the IC card 200. This can be explained in detail as follows. First, in step S8, loading of the IC card 200 continues as it is, and when the IC card 200 reaches a predetermined card loading position, the microswitch 106 is turned on (or turned off). As a result, the data processing/control unit 102 turns off the card drive unit 104. The card loading section 101 includes a device 1 connected to the terminal 202 of the IC card 200.
A contact pin on the 00 side is provided, and as will be explained in detail in FIG. 3 and FIG. It is adapted to come into contact with the terminal 202. Therefore, the data processing/control unit 100
After the card 200 reaches the predetermined loading position, the module reading/writing section 107 is turned on and the IC card 200 is loaded.
Execute data transmission between. The above is IC card 20
0 access processing.

On the other hand, if the IC card 200 does not have the magnetic recording section 201, the process moves from step S4 to step S.
Furthermore, even if the magnetic recording section 201 is included, if it is not compatible with the apparatus, the process moves from step S[gamma] to step S9. In this step S9, data processing and
The control unit 102 drives the display unit 10B and displays the IC card 20.
An error message is displayed indicating that 0 is inaccessible to the device 100. After this, data processing/control unit 1
02 moves to step S1° and controls the card drive section 104 so that the IC card 200 is removed. As a result, 9. the IC card 200 is removed from the card loading section 101 before reaching the predetermined card loading position.

The overall configuration and operation of this embodiment are as described above, but before explaining the remaining configuration shown in FIG. The configuration and operation will be explained.

FIG. 3 is a plan view of the card loading section 101, and FIG. 4 is a side view. Note that the same parts in FIGS. 3 and 4 as in FIG. 1 are given the same reference numerals.

First, when the IC card 200 is inserted into the card insertion slot IIL, the microswitch 103 is turned on, and the motor 1b of the card drive unit 104 is turned on. The rotation of the motor 1b is transmitted to the roller 3a via a bell 21L, thereby driving the roller 3a to rotate. Thereby, the IC card 200 is guided into the card loading section 101 so as to be sandwiched between the roller 3a and the opposing roller 4a.

During the above-mentioned transportation process, the IC card 200 is transferred to the slide member 5.
It fits into the 1L recess 6a and pushes the slide member 5a in the card insertion direction xl.

The slide member 5a is held by the holding members 7h and 8a.
It is held slidably in the card insertion direction X1 and the card removal direction X2, and is always urged in the card removal direction X2 by a spring (not shown). An arm member 10h that supports the contact pin portion 9a is held on the slide member 5a so as to be slidable in the vertical direction in FIG. 4. The arm member 10h is attached to a cam Il formed on the holding member 7a as the slide member 5a slides in the direction of the illustrated arrow (Xt←Xt).
It moves up and down guided by h.

That is, when the slide member 5a is pushed by the IC card 200 and slides in the card insertion direction Xi, the arm member 10a descends, and when the IC card 200 reaches a predetermined card loading position, it is attached to the arm member 10h. The contact bin provided in the contact bin portion 9a contacts the terminal 202 of the IC card 200. At the same time, the microswitch 106 is turned on and the rotation of the motor 1b is stopped. On the other hand, if the IC card 200 cannot be accessed by the device 100, the IC card 200 reaches the predetermined card loading position. Before the motor 1b is driven in reverse, I
Since the C card 200 is transported in the card removal direction X, it will not be accessed.

The magnetic reading section 105 that reads magnetic data from the magnetic recording section 202 of the IC card 200 is connected to the magnetic recording section 20
The IC card 200 is provided during transportation of the IC card 200 so that magnetic data can be read while the IC card 200 is being transported.

The card loading section 101 of this embodiment is constructed as described above, but now, referring back to FIG. 1, the structure other than the one that characterizes this embodiment will be explained.

The data processing device shown in FIG. 1 is for use in a banknote handling system used, for example, in banks.

That is, 109 is a banknote counting section, and 110 is a banknote storage cassette. Reference numeral 111 is a journal printer for printing out bank documents (journals). 112 is an imprinter that prints out a slip for the user.

Further, 113 is an operation key, and 114 is a power supply unit.

As described in detail above, in this embodiment, only when the IC card 200 has the magnetic recording section 202 and is compatible with the device 100, the process moves to step S8 to access the IC card 200, and in other cases, the IC card 200 is accessed. It is no longer accessible.

Therefore, according to this embodiment, a user accidentally inserts an IC card 200 that does not have a magnetic recording section 201 into the device 100.
Even if an attempt is made to load the card into the card, it will not be accessed, so destruction of the module, damage to the surface of the card body, damage to the contact bin, etc. can be prevented.

Note that the present invention is not limited to the above embodiments.

For example, in the previous embodiment, the I
Although the description has been given of the device fRI00 that can access the C card 200, it goes without saying that the present invention can also be applied to devices that have the magnetic recording section 202 and that can access the IC card 200. In this case, for example, the determination in step S4 in FIG. 2 may be reversed from that in the previous embodiment. Further, in this case, the processing of steps 85 to S7 is unnecessary. However, regarding this point, if there is no need to collate the decoding results in the previous embodiment, it is also unnecessary.

Furthermore, in the above explanation, the magnetic reading section 105, which is used for magnetic reading for decoding magnetic data, is used as the response means of the magnetic recording section 201. A separate device may be provided for detection. This is because a configuration that responds to the magnetic recording section 201 can be realized at low cost in a device that does not have the above-mentioned magnetic reading section 105, such as a device that can access the IC card 200 that does not have the magnetic recording section 201. It is valid.

Furthermore, since the present invention determines the presence or absence of the magnetic recording section 201 and accesses a predetermined IC card 200 according to the determination result, it is possible to apply the card loading section 10 to devices 100 other than automatic slide systems. Of course.

〔Effect of the invention〕

As detailed above, according to the IC card data processing device of the present invention, when an IC card of a different standard is loaded, access to it is prohibited, so destruction of the module etc. can be reliably prevented. .
