Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing the ejection of an IC card that is properly installed in a mounting section in a reader/writer, and particularly for preventing the removal of an IC card when the IC card is installed in a proper position. The present invention relates to an IC card removal prevention device which operates an interlock means by mechanical detection and a signal sent by the activation of a switch, and locks an operating lever during reading/writing of the IC card.

[Conventional technology]

BACKGROUND ART Today, IC cards in which a built-in IC having memory and CPU functions is formed into a card shape are in widespread use. In general, this IC card has IC electrical contacts on the outer surface of the card as a means for reading and writing data, and contacts these electrical contacts to supply power to the IC card and send and receive data signals. A reader/writer configured to perform this is used.

As the memory capacity of this type of IC card increases, its uses have expanded, and it has become convenient and effective not only as a variety of business cards for personal use, but also as a memory medium for program control systems in various industries. It is used for. IC cards are becoming more versatile in this way.
As the frequency of use increases, the environment in which it is used becomes more susceptible to external contamination and damage, which causes the electrical contacts to deteriorate, making it impossible to properly send and receive data signals.

From this perspective, we create a field of vibrational energy due to high-frequency electromagnetic fields and ultrasonic waves in space, and absorb the energy of this field.
By rectifying the DC power, it eliminates the need for built-in batteries or power supply contacts in IC cards, and also uses couplers such as antennas and coils to exchange various data signals with the reader/writer. By embedding this coupler in the appropriate location of the IC card, an IC card system is created in which all electrical contacts exposed to the outside of the IC card are omitted, and the electrical connection between the IC card and the reader/writer is made contactless. It has been proposed (for example, Japanese Unexamined Patent Publication No. 58-15
4082).

When connecting an IC card and a reader/writer using such a contactless connection method, in order to efficiently supply power to the IC card and manually input data signals, it is necessary to connect the coupler and reader/writer provided on the IC card. It is desirable that the positional alignment be performed with the coupler provided in the

[Problem to be solved by the invention]

Therefore, when connecting an IC card and a reader/writer using such a contactless connection method, in order to insert the IC card into the reader/writer in the correct state, it is necessary to determine the front and back of the IC card and the insertion direction. It is possible to employ means such as printing the obtained display on the IC card and providing an insertion position defining frame on the reader/writer side for properly positioning the IC card.

However, as mentioned above, even if an IC card is printed with instructions for proper insertion into a reader/writer, incorrect insertion may occur due to a mistake on the part of the handler, and in such cases, A means for determining the proper positioning state of the IC card is required on the reader/writer side.

Furthermore, the reader/writer is equipped with a means for determining this state and fixing the IC card so that it cannot be moved only when the IC card is in a proper positioning state, thereby supplying power to the IC card. It is also necessary to send and receive data signals.

Therefore, these discriminating means and fixed holding means must each have a complicated structure using electrical, mechanical, or optical means, and in such a conventional structure, the reader/writer and the IC card are If the IC card is transferred due to some kind of failure during signal transmission/reception, the electrical connection will be broken and the memory in the IC card will be lost or the system will be destroyed. Furthermore, the conventional configuration has the disadvantage that the manufacturing cost of the reader/writer increases significantly.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make it easier to identify an IC card to an IC card reader/writer so that the IC card can always be inserted in a certain direction, and to position the IC card at the correct insertion position. In addition, the movement of the IC card operating section is restrained during reading and writing of the IC card to ensure the execution of reading and writing and prevent erroneous operation. To provide an IC card removal prevention device.

The present invention is characterized in that an operating lever is provided, and interlock means is provided that is electrically controlled to lock or release the operating lever.

In this case, the operating lever has an engaging portion that engages with one end of the lever member, and a locking piece at the tip thereof, and is provided so as to be slidable in the same direction as the moving direction of the slide plate. , and an eject lever biased toward the operating side.

Further, the interlock means includes a lock lever that is pivotably provided near the locking piece of the eject lever, one end of the lock lever is engaged with a drive source, and the other end is engaged with the locking piece by the drive source. It is preferable to configure it so that it approaches and separates from the piece.

Further, it is preferable that the driving source is configured to include a solenoid and to displace the lock lever by excitation of the solenoid.

[Effect]

According to the IC card removal prevention device according to the present invention,
By inserting an IC card having notches provided at asymmetrical positions on both longitudinal edges, the leading end of the IC card engages with the slide plate and moves forward together with the slide plate to a predetermined position.

In this case, the slide plate that corresponds to and covers the notch provided on one side edge of the IC card and the lid plate each have a cutout and a notch step, so when the slide plate moves to a predetermined position, it returns to its original position. The engaging part of the auxiliary lock lever, which constantly presses one side edge of the resilient slide plate, is recessed into the cutout part, and the lock pin of the auxiliary lever enters the notch step part, and at the same time, it locks one side of the IC card. Fits into the notch.

Furthermore, a cutout is provided on the other side edge of the cover plate corresponding to the notch of the IC card, and the extension part provided on the other side edge of the slide plate is in contact with the lock lever. At this point, a portion of this lever fits into the notch on the other side edge of the IC card.

As a result, an IC card in an incorrect state cannot be inserted because the notch does not match, and can only be inserted into a specified position in an appropriate state, making it possible to mechanically detect an IC card, for example. Execution of read/write is started by the power ON signal from the external device, and the operation lever for removing the IC card is turned off by the operation of the interlock means to prevent erroneous operation during execution of read/write, and the IC card is removed. It is possible to more reliably transmit and receive signals with the user.

After the components are mounted, they can be easily molded by covering them with a synthetic resin covering material by a known laminating method or bonding method.

However, in the present invention, I

Achieve fixed retention. That is, in the ICC node 10 of this embodiment, the input coil 14 and the output coil 16, which have different functions, are built in asymmetrically, and only when in a constant state with the corresponding input/output means provided in the reader/writer. (The front side of the IC card and the direction of insertion into the reader/writer are determined). Therefore, for example, IC card 1

Next, a reader/writer equipped with a detection mechanism suitable for the IC card of the present invention having the above-described configuration will be described.

First, as shown in FIG. 6, the basic configuration of the reader/writer includes a herad core 30 for supplying power and data signals to the input coil 14 of the IC card 1o, and an IC

connected to.

Therefore, the reader/writer configured in this manner includes the head core 30, the input coil 14 of the IC card, and the receiving coil 3.
By providing detection mechanisms corresponding to the notches 20 and 22 provided in the IC card 10, when the output coil 16 of the IC card and the output coil 16 of the IC card are properly positioned to face each other, the proper state of the IC card can be detected. Discrimination and fixed holding of the IC card can be achieved smoothly and reliably.

1, 2, and 3 show the above-mentioned IC card 1.
1 shows an embodiment of a reader/writer equipped with a removal prevention device suitable for a zero detection mechanism. That is, FIGS. 1 and 2 show the planar structure of the main part of the IC card mounting section, and show the state before and after the IC card is mounted, respectively. In the figure, reference numeral 40 is an IC card 10.
It shows an insertion opening for storing and holding the 7.5mm in a predetermined position, and below it there is a guide side plate 42 configured as shown in Fig. 3.
It is provided with a base plate 44 extending at an angle of 42 degrees, and a protective cover plate 46 on the upper side, and the base plate 44 and the cover plate 46 are fixedly arranged via appropriate coupling devices.

The lid plate 46 has two notches 48 and 5 at its tip, respectively.
0/fi, the helad core 30 is disposed in one notch 48, and the other notch 50 is formed as a guide groove for a tip locking portion 52 of a slide plate 54, which will be described later.

However, the slide plate 54 is arranged on the upper surface of the cover plate 46, and has a plurality of guide grooves 56 bored in the same direction as the insertion direction of the IC card 10, and the cover plate 4 is inserted into each of these guide grooves 56.
A stop pin 58 fixed to 6 is fitted to make it slidable.

In this case, each end of the coil spring 60 is engaged with a portion of the slide plate 54 and a portion of the cover plate 46, respectively, so that the slide plate 54 maintains its return elasticity. Further, one side edge of the slide plate 54 is positioned so as to substantially coincide with one side edge of the cover plate 46 . In this case, a cutout 62 and an opening 163 are provided on one side edge of the cover plate 46 at the portions where the cutout 20 is located when the IC card 10 is completely inserted (see FIG. 2); A lever 68 is provided with a lock pin 66 that fits inward (into the notch 2o of the IC card 10) from the outside by the elasticity of a spring 64 with respect to the cutout 62 and the opening 63. moreover,
In order to further ensure that the IC card 10 is fixedly held by the lock bin 66, an auxiliary lock lever 98 that interlocks with the lock bin 66 is provided on one side edge of the slide plate 54.

That is, this auxiliary lock lever 98 loosely fits the lock pin 66 into its substantially middle portion, has a lower end pivotally attached to the lid plate 46 via a stop pin 100, and has an engaging portion on the lower surface of the other end. It has a configuration in which a protrusion 102 is provided and this protrusion 102 abuts one side edge of the slide plate 54.

In this case, the slide plate 54 is moved forward and the IC card 10 is placed on one side edge of the slide plate 54 that the protrusion 102 contacts.
a cutout 104 that deflects the auxiliary lock lever 98 inward to allow the lock pin 66 to fit into the notch 20 when the lock pin 66 reaches a predetermined most extreme position (FIG. 2);
will be established.

In this way, the other end of the auxiliary lock lever 98 is largely deflected inward, causing the notch 2 of the IC card 10 to
This makes it possible to stabilize the locking bin 66 fixedly held against the zero. Moreover, when the slide plate 54 is in the return position, the protrusion 102 of the auxiliary lock lever 98 is in contact with one side edge of the slide plate 54, and in this case, the lock bin 66 is placed on the card side when inserting the IC card. Since it is located away from the edge, it will not damage the IC card.

On the other hand, a second cutout 84 is provided on the other side edge of the cover plate 46 corresponding to the other notch group 22 of the IC card 10, a locking piece 86 is provided at one end of the second cutout 84, and a spring 88
A lock lever 90 is provided which operates to engage against the elastic force of the lock lever 90. A locking piece 96 protruding from an extension 94 of the slide plate 54 is arranged opposite to a locking pin 92 provided at the other end of the lock lever 90. With this configuration, the leading end of the IC card 10 engages with the locking portion 52 of the slide plate 54, and the IC card 10 is attached to the slide plate 54 together with the IC card 10.
When the IC card 10 moves forward and reaches the predetermined most extreme position, the locking piece 96 provided on the extension 94 of the slide plate 54 comes into contact with the locking pin 92 of the lock lever 90.
At the same time as this is suppressed and displaced, the locking piece 86 of the lock lever 90 fits into the notch 22 of the IC card 10, so that the IC card 10 can be fixed and held from both sides. In this case, the limit switch 78 is arranged as shown in the figure, and its actuator 80 is connected to the extension part 9 of the slide plate 54.
4 can be configured to operate in part. Therefore, if the IC card 10 does not have something corresponding to the notch 22, the displacement of the lock lever 90 is prevented and the forward movement of the slide plate 54 is also prevented, and as a result, the limit switch 78 is not operated at all. It is possible to prohibit the insertion of an IC card without having to do so.

Next, a detection device that detects the state in which an IC card is inserted will be described. A limit switch 78 constituting a part of this detection device is provided on the other side edge of the slide plate 54, and when the slide plate 54 moves forward in cooperation with the insertion of the IC card 10, the extension portion 94 of the slide plate 54 The locking piece 96 provided on the lock lever 90 and the locking pin 92 of the lock lever 90
The lock lever 90 is pivoted around the hour h1 to fit the locking piece 86 into the notch 22 of the IC card 10, and this state is electrically detected. That is, as shown in FIG. 2, by the pivoting action of the lock lever 90,
This lock lever 90 comes into contact with the actuator 80 of the limit switch 78, turns on the limit switch 78, and starts operating the reader/writer.The ejector, which is a card ejecting device described later, is activated by a power ON signal from an external device. Lever 82 is locked. However, the limit switch 78 detects the IC card installation state only after the IC card 10 is completely installed in the reader/writer at the proper position and the notches 20 and 22 of the IC card are mechanically detected. Electrical detection is now possible, making reading and writing of some IC cards more reliable than before, and furthermore, during reading and writing,
An interlock works to prevent the C card from being removed, thereby preventing erroneous operation.

Next, an embodiment of the IC card removal prevention device according to the present invention will be described with reference to FIGS. 1 and 2 in relation to the removal device.

As shown in FIG. 2, the IC card ejection device returns the lever 68 to the outside by pressing the eject lever 82 in the direction of the arrow when ejecting the IC card 10 fixedly held in the IC card mounting section. lock bin 6
6 was released from the notch 20 (13) of the IC card 10 and the notch step 70 of the slide plate 54, and the IC card 10 was locked by the elastic action of the coil spring 60 on the slide plate 54 as shown in FIG. It is configured to return the slide plate 54.

More specifically, an eject lever 82 is provided so as to be movable back and forth parallel to the side surface of the substrate 44 in the direction of the arrow while being guided by a stop pin 112 in a guide groove 110. Further, a spring 116 is attached to a locking piece 114 provided at the head of the locking pin 112 and one end of the guide groove 110, and urges the eject lever 82 outward. Further, a locking piece 118 is formed at the tip on the entry side of the eject lever 82, and a long groove 120 is bored inside the locking piece 118.

The operating portion 12 of the operating lever 68 is inserted into this long groove 120.
4 is engaged with a pin 122 implanted below.

The long groove 120 prevents any force from being applied to the eject lever 82 even if the operation lever 68 pivots together with the auxiliary lock lever 98 due to the movement of the slide plate 54 when the IC card 10 is inserted. As shown in Figure 2, I
When the C card 10 is in the device state, the pin 122 of the operating lever 68 is in contact with one end of the long groove 120.

Therefore, when the eject lever 82 is pressed in the direction of the arrow, the operating lever 68 pivots counterclockwise, and this pivoting stops the auxiliary mortar lever 98 and causes the spring 6 to move around the bottle 100.
Pivot clockwise against the biasing force of IC card 1.
The lock bin 66 is removed from the notch 20 of 0 and the notch step 70 of the slide plate 54.

Furthermore, at the same time, the protrusion 102 of the auxiliary lock lever 98 also escapes from the cutout 104 of the slide plate 54. This results in
A slight backward movement of the slide plate 54 causes the lock lever 90 to be disengaged from the locking piece of the extension part 94 of the slide plate 54, so that the locking piece 86 is moved to the other side of the IC card by the action of the spring 88. The IC card 10 is removed from the notch 22, and the IC card 10 is returned to the IC card insertion side together with the slide plate 54 to the insertion starting position by the action of the spring 60, and becomes ready for removal.

Next, in relation to the eject lever mentioned above, I
The C card removal prevention device will be explained.

Even if the IC card 10 is installed in the IC card slot of the reader/writer in a proper state and is held mechanically fixed, there may be a problem when electrical connection is made to the IC card and information is being read or written. If the eject lever 82 is pressed carelessly, the IC card may be moved, the electrical connection may be broken, the memory within the IC card may be lost, or the system may be destroyed.

Therefore, since reading/writing of the IC card is started by a power ON signal from an external device, the movement of the eject lever 82 is locked by an interlock means during that time.

That is, as shown in FIGS. 1 and 2, a drive source 126, which is an interlock means and is operated by excitation of a solenoid, for example, is disposed at a position facing the locking piece 118 at the tip of the eject lever 82. A lock lever between this drive source 126 and the eject lever 82 that can be swung to 1rrI.
128 is provided. This lock lever 128 is pivotally supported at the center by a pin 130, one end thereof is pivotally supported by an operating rod 132 which is moved forward and backward by the drive 11i126, and a stopper pin 134 is installed at the other end. Furthermore, the lock lever
The other end of 128 is connected to the board 44 side (the locking piece 1 by a spring 136).
18).

Therefore, when the IC card 10 is installed in a predetermined position, the lock lever 90 pivots mechanically in conjunction with the forward movement of the slide plate 54, as described above, which activates the limit switch 78, and this signal The read/write operation is started, and the power is turned on from the external device.
In response to the signal, the solenoid of the drive #J source 126 is energized, causing the operating rod 132 to move backward. This backward movement releases the lock lever.
128 swings, and the stopper bin 134 is located at a position immediately adjacent to the locking piece 118 of the eject lever 82 (the position indicated by the two-dot chain line in FIG. 1).

As a result, the forward motion of the eject lever 82 is blocked by the stopper bin 134, resulting in a locked state, and malfunction of the reader/writer can be reliably prevented.

〔Effect of the invention〕

As is clear from the above embodiments, according to the tree invention,
By providing a plurality of notches on both edges in the longitudinal direction of the IC card, when inserting the IC card into the IC card slot of the reader/writer, the IC card is moved forward together with the slide plate having return elasticity, and is held at a predetermined position. By configuring the lock pin to fit into the notch of the IC card, it is possible to easily and reliably insert and hold the IC card. Furthermore, the notch of the IC card can prevent insertion before the IC card reaches a predetermined mounting position in the event of incorrect insertion. In addition, a signal sent from a switch that operates at the same time as mechanically detecting the proper insertion state of the IC card enters the state where read/write execution is started for the first time, and a power ON signal from an external signal device causes the interface to be activated. The operation lever for removing the IC card is locked by the operation of the locking means,
Erroneous operations during read/write execution are prevented, signals can be sent and received with the IC card more reliably, and the reliability of the reader/writer is guaranteed.

The operating lever has an engaging portion that engages with one end of the lever member and is provided with a locking piece at the tip thereof, and is provided so as to be movable in the same direction as the moving direction of the slide plate, and an eject lever biased toward the operation side, and the interlock means includes a lock lever pivotably provided near a locking piece of the eject lever; One end is engaged with a drive source, and the other end is configured to move toward and away from the locking piece by the drive source. Therefore, even if an external force is applied to the eject lever due to an erroneous operation, the locking piece and the lock lever are locked to each other on the line of action of the external force. Therefore, the lock lever is not pivoted by external force, and the drive source is not loaded with external force, making it possible to use a low-output drive source, reducing power consumption and simplifying the configuration. can be downsized and reduce manufacturing costs.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and does not depart from the spirit of the present invention. Various design changes are possible within this range.
