Description

Card Processing Devices and Automatic Transaction Devices

technical field

The present invention relates to a card processing device and an automatic transaction device, and particularly relates to a technique suitably applied to a card processing device and an automatic transaction device provided with a prevention mechanism for preventing unauthorized removal of a card.

Background technique

Usually, automatic transaction apparatuses, such as an automatic teller machine, are provided with the card processing apparatus, and are comprised. The card processing device transports a card, such as a magnetic card or an IC card, on which various information is recorded, from the insertion port toward the inside of the device, and when it is transported to a predetermined position, reads the information pre-recorded on the card using a magnetic head or an IC contact unit. , and write new information to the card.

However, since important information such as personal information and transaction information is recorded in the card, there are people who intend to obtain the card illegally (card phishing) and use it maliciously. As a representative example of fraudulent acts, there are the following fraudulent acts: implement tricks on the card processing device in advance, so that if the card is inserted into the card processing device, the card will be stuck near the insertion port, and the card user will work in order to make a call. When people leave the scene, use tools to remove the stuck card.

Patent Document 1 discloses a card processing device including a prevention mechanism for preventing such fraudulent acts. Specifically, the following structure is disclosed: the prevention mechanism is provided with an eccentric cam, and the outer peripheral part with a shorter distance from the rotating shaft to the outer periphery is directed toward the card conveying path in normal times, and the eccentric cam is rotated in abnormal conditions to make the outer peripheral portion from the rotating shaft to the outer periphery. The outer peripheral portion with a longer distance faces the card conveying path so that the outer periphery of the eccentric cam contacts the card.

According to this patent document 1, it is configured that the blade provided on the outer periphery of the eccentric cam comes into contact with the card only by operating the blocking mechanism once to rotate the eccentric cam. Due to the friction between the blades, the eccentric cam rotates further and the blade cuts into the card, so it can prevent the card from being pulled out.

Contents of the invention

The problem to be solved by the invention

In the structure described in Patent Document 1, in a blocking state where the blade of the eccentric cam abuts against the card, it is firmly fixed so that the card cannot be removed or further inserted (see Example 6 of Patent Document 1). In addition, in this case, a lever that rotates together with the eccentric cam and a fixing tool that fixes the lever are provided. In order to release the blocking state, two operations of rotating the lever after rotating the fixture are required (see paragraph [0116] of Patent Document 1).

That is, in the structure described in Patent Document 1, in order to securely fix the card in the blocked state, a fixing tool is required in addition to the lever. As a result, the number of parts increases, so there is a problem of increasing the size of the entire device. In addition, in the case of releasing the blocked state, it is necessary to perform the two operations of operating the lever after operating the fixing tool in an appropriate order of operations, and the blocked state cannot be released without grasping the release operation. Dismissed subject.

In addition, in the structure described in Patent Document 1, if the card is to be pulled out from the insertion port in the blocked state, the blade of the eccentric cam cuts into the card, but even if the card is further pushed in the insertion direction, the blade will not Will not cut into the card. Utilizing this, for example, a card-shaped thin plate (for example, a backing plate) can be inserted between the blade of the eccentric cam and the card in a blocking state in a sliding manner.

At this time, only the force in the insertion direction of the backing plate is applied to the eccentric cam, and the blade does not cut into the card or the backing plate. If the card is moved in the extraction direction while the position of the backing plate is fixed while the backing plate is inserted between the blade of the eccentric cam and the card, the card can be easily pulled out from the insertion port. Therefore, in order to more firmly prevent the card from being caught, it is necessary to have a structure that prevents foreign matter from being inserted between the blade of the eccentric cam and the card in the prevented state.

The present invention is made in consideration of the above problems, and proposes a device that securely fixes the card in the blocked state and realizes the miniaturization of the entire device and the simplification of the release operation, and can prevent foreign objects from being inserted between the blade and the card. Card processing devices and automatic transaction devices.

means to solve problems

In order to solve such a problem, it is characterized in that the prevention mechanism includes a first prevention member, a second prevention member, a link member, and a cover member; the first prevention member operates to release the second prevention member when the prevention state release lever is pressed Restriction of the action; the second blocking member acts when the blocking state release lever is pressed to release the state that the blade is in contact with the card; the link member connects the first blocking member and the second blocking member, so that the lever is released in the blocking state When pressed down, the second preventing member operates in conjunction with the action of the first preventing member; the cover member operates when the preventing state releasing lever is pressed down, so as to release the state in which the end portion abuts against the card.

Invention effect

According to the present invention, the card is firmly fixed in the blocked state, the overall size of the device is reduced and the release operation is simplified, and foreign matter can be prevented from being inserted between the blade and the card.

Detailed ways

(1) Structure of card processing device

FIG. 1 shows the overall configuration of a card processing device 1 according to this embodiment. When a card on which various information is recorded, such as a magnetic card or an IC card, is inserted from an insertion slot, the card processing apparatus 1 conveys the card to a predetermined position. Then, information pre-recorded on the card is read using the magnetic head 20 or an IC contact unit (not shown), or new information is written to the card.

The card processing apparatus 1 is provided with the conveyance roller 10, the magnetic head 20, the head opposing roller 25, the prevention mechanism 30, etc., and is comprised. The pair of conveyance rollers 10 are disposed vertically opposite to the conveyance line X, and rotate so as to convey the card along the conveyance line X. Here, a pair of conveying rollers 10 is illustrated as conveying the card from right to left.

The magnetic head 20 is provided between two sets of conveying rollers 10 arranged in front and behind in the direction of the conveying line X, and is disposed directly below the conveying line X. As shown in FIG. The magnetic head 20 reads fixed data such as personal information recorded on a card transported along the transport line X. The head opposing roller 25 is provided on the magnetic head 20 and pushes the card conveyed on the magnetic head 20 so that it can be read.

The blocking mechanism 30 is provided near the insertion port. If an abnormality is detected by a sensor (not shown in the figure) or the like, the preventing mechanism 30 operates so that the blade equipped on the end contacts the card, and if the card is to be pulled out, the blade is cut into the card to securely fix the card so that Cannot be selected. In addition, the sensor detects an abnormality, for example, when the pair of conveyance rollers 10 closest to the insertion port are rotated but the card is not actually conveyed.

By providing the preventing mechanism 30, it is possible to prevent the card processing apparatus 1 from cheating in advance to intentionally jam the card, and to use a tool or the like to remove the jammed card in the space where the card user leaves the site to call the staff. (card fishing).

In this embodiment, the blocking mechanism 30 is downsized, and the release operation is simplified when the blocking state after the blocking mechanism 30 is activated is released. In addition, in the prevented state, the insertion of a thin plate such as a backing plate between the blade and the card is prevented, thereby further strengthening the prevented state. Hereinafter, a detailed configuration of the prevention mechanism 30 will be described with reference to FIGS. 2 to 6 .

(2) Structure of blocking mechanism at the time of normal transactions

FIG. 2 shows the overall structure of the blocking mechanism 30 during normal transactions. The card is conveyed in the card conveyance direction X1 (from right to left). The prevention mechanism 30 includes an actuator 31 , a tension spring 32 , a first prevention member 33 , a link member 34 , a second prevention member 35 , a compression spring 36 , a base 37 , a cover member 39 , and the like.

The actuator 31 is equipped with the movable iron core 311 which can attract, and attracts the movable iron core 311 when abnormality is detected by a sensor. In addition, here, the suction direction is a direction from the front side of the page (the user side) toward the rear side. When the actuator 31 attracts the movable iron core 311, the arm 38 (see FIG. 6 ) connected to the movable iron core 311 moves.

During normal transactions, the actuator 31 does not attract the movable iron core 311, and the arm 38 connected to the movable iron core 311 does not move. Therefore, the state where the groove 351 is engaged with the end portion 381 of the arm 38 is maintained. In this case, the second prevention member 35 is supported by the arm 38 while being retracted from the card by a certain distance.

The tension spring 32 is spanned by the spanning member 101 formed on the bracket 100 (see FIG. 6 ) and the spanning member 331 formed on the first prevention member 33 . The extension spring 32 applies tension to the erecting member 331 in a direction in which the first preventing member 33 rotates counterclockwise, but during normal transactions, the first preventing member 33 is restricted from rotating by the second preventing member 35 and is supported as a tension spring. 32 pull does not rotate.

The first preventing member 33 is an eccentric cam whose distance from the rotating shaft 332 to the first concave-convex portion 333 is not uniform. In addition, a blocked state releasing lever 334 is formed on the first blocking member 33 . In this embodiment, only by pressing down the blocking state releasing lever 334, the blocking state ( FIG. 4 , FIG. 5 ) can be released and the normal transaction state ( FIG. 2 , FIG. 3 ) can be formed. During normal transactions, the rotation of the first prevention member 33 is restricted by the second prevention member 35 and supported.

The link member 34 is connected to the first prevention member 33 at one end and the second prevention member 35 at the other end, thereby connecting the first prevention member 33 and the second prevention member 35 to operate in conjunction with each other.

The second prevention member 35 is an eccentric cam that includes a rotation shaft 353 and a blade 354 in addition to the groove 351 and the second concave-convex portion 352 , and the distance from the rotation shaft 353 to the tip of the blade 354 is not uniform. During normal transactions, the second prevention member 35 is supported by the arm 38 in a state in which the blade 354 is evacuated from the card by a certain distance from the rotation of the arm 38 . On the other hand, the second prevention member 35 restricts the rotation of the first prevention member 33 and supports the first prevention member 33 .

One end of the compression spring 36 is connected to a part of the second prevention member 35 , and the other end is movably in contact with the wall 102 of the bracket 100 (see FIG. 6 ). The compression spring 36 applies a urging force to the second preventing member 35 in a direction to rotate the second preventing member 35 counterclockwise, but during normal transactions, the second preventing member 35 is restricted from rotating by the arm 38 in a state retracted by a certain distance from the card. And be supported.

FIG. 3 shows the overall structure of the prevention mechanism 30 of FIG. 2 when viewed from the opposite direction (the back side of the page). Therefore, the card is conveyed in the card conveyance direction X1 (from left to right). Here, the cover member 39, the tension spring 40, and the protrusion 335 are demonstrated especially. During normal transactions, the cover member 39 is supported by the protrusion 335 in a state where the end portion is retracted from the card by a certain distance.

The tension spring 40 is stretched over the protrusion 103 formed on the bracket 100 and the spanning member 391 formed on the cover member 39 . The tension spring 40 applies a pulling force to the cover member 39 downward, but during normal transactions, the cover member 39 is restricted from moving by the protrusion 335 and is supported so as not to move downward under the tension of the tension spring 40 .

The protrusion 335 is a protrusion formed on the first prevention member 33, and supports the cover member 39 in a state retracted from the card by a certain distance. In addition, the protrusion 335 moves up and down in conjunction with the operation of the first prevention member 33 . Here, when the first prevention member 33 rotates counterclockwise (clockwise in FIG. 2 ), the protrusion 335 moves upward. At this time, the protrusion 335 moves the cover member 39 upward against the tension of the tension spring 40 .

That is, in the present embodiment, the projection 335 can move the cover member 39 upward in conjunction with the counterclockwise rotation of the first prevention member 33 simply by pressing the prevention state release lever 334 . And, if the second prevention member 35 is supported by the arm 38 , the first prevention member 33 is supported by the second prevention member 35 . As a result, the cover member 39 can be supported and fixed by the protrusion 335 of the first prevention member 33 .

(3) Structure of the blocking mechanism in the blocking state

FIG. 4 shows the overall structure of the blocking mechanism 30 in the blocking state. The card is conveyed along the card conveyance direction X1 (from right to left). When the actuator 31 attracts the movable iron core 311 from the front to the rear side of the drawing, the arm 38 (see FIG. 6 ) connected to the movable iron core 311 moves. This blocking state is formed when the end portion 381 of the arm 38 is disengaged from the groove 351 ( FIGS. 4 and 5 ).

The tension spring 32 applies tension to the bridging member 331 to rotate the first preventing member 33 counterclockwise, and when the end 381 of the arm 38 is disengaged from the groove 351 , the first preventing member 33 is rotated counterclockwise by the tension.

The first preventing member 33 is tensioned by the tension spring 32 via the bridging member 331, and if the end 381 of the arm 38 breaks away from the groove 351, the support performed by the second preventing member 35 is released, and the first preventing member 33 rotates about the axis of rotation. 332 is that the shaft rotates counterclockwise. In addition, when the first uneven portion 333 formed at the end portion of the first prevention member 33 comes into contact with the second prevention member 35 , the rotation of the first prevention member 33 is stopped to form a prevention state.

In addition, as described above, the first preventing member 33 is an eccentric cam whose distance from the rotating shaft 332 to the first concave-convex portion 333 is not uniform. Therefore, even when the second preventing member 35 rotates counterclockwise after the first concave-convex portion 333 comes into contact with the second preventing member 35 , the contact state can be maintained.

If the first concave-convex portion 333 contacts the second preventing member 35, the first concave-convex portion 333 engages with the second concave-convex portion 352 formed at the end of the second preventing member 35, preventing the second preventing member 35 from rotating clockwise. . Also, counterclockwise rotation is not prevented.

In addition, a blocked state releasing lever 334 is formed on the first blocking member 33 . When the blocking state releasing lever 334 is pushed in the releasing direction, the first blocking member 33 rotates clockwise around the rotation shaft 332 against the tension of the tension spring 32 . After clockwise rotation, the rotation is restricted by the second prevention member 35 and supported. And, a normal transaction state (Fig. 2, Fig. 3) is formed.

The link member 34 does not act on the first blocking member 33 and the second blocking member 35 in the blocking state shown here, but when the blocking state release lever 334 is pressed from the blocking state and the first blocking member 33 clockwise When rotating, the second preventing member 35 is rotated clockwise in conjunction with the rotating operation of the first preventing member 33 .

Here, the action of the link member 34 will be described. When the blocking state release lever 334 is pushed down, the first blocking member 33 resists the tension of the tension spring 32 and rotates clockwise around the rotation shaft 332 . And, at this time, the first prevention member 33 lifts up one end of the connected link member 34 upward.

When one end of the link member 34 is lifted upward by the rotation operation of the first preventing member 33 , the entire link member 34 moves upward. And, the other end applies a force of lifting upward to the second prevention member 35 . The second prevention member 35 rotates clockwise around the rotation shaft 353 against the biasing force of the compression spring 36 when a force of upward lift is applied from the other end of the link member 34 .

When the second prevention member 35 is rotated clockwise, the groove 351 moves to a predetermined position. The predetermined position refers to a position where the end portion 381 of the arm 38 is arranged. When the groove 351 moves to a predetermined position, the groove 351 engages with the end portion 381 of the arm 38 , and the second prevention member 35 is supported and fixed by the arm 38 . As a result, the blocked state is released.

When the depressed blocking state release lever 334 is released, the first blocking member 33 is pulled by the tension spring 32 and slightly rotates counterclockwise around the rotation shaft 332 . Furthermore, when the vicinity of the lower end of the first concave-convex portion 333 comes into contact with the vicinity of the upper end of the second concave-convex portion 352 , the first preventing member 33 is supported by the second preventing member 35 to stop its rotation. Thereby, the normal transaction state (FIG. 2 and FIG. 3) before an abnormality is detected is formed.

When the end portion 381 of the arm 38 is disengaged from the groove 351 , the second prevention member 35 is biased by the compression spring 36 and rotates counterclockwise around the rotation shaft 353 . And, when the blade 354 formed on the end of the second prevention member 35 contacts the card, the rotation is stopped to form a prevention state.

Moreover, the 2nd prevention member 35 is an eccentric cam whose distance from the rotation shaft 353 to the front-end|tip of the blade 354 is uneven. Therefore, even when the second prevention member 35 rotates counterclockwise after the blade 354 contacts the card, the contact state can be maintained.

If the blade 354 is in contact with the card, the blade 354 pushes the card against the base 37, and a frictional force acts between the blade 354 and the card. When the card is turned to the right (opposite to the card conveying direction X1) in the state where this frictional force acts, the second prevention member 35 receives the frictional force and further slightly rotates counterclockwise. As a result, the card cannot descend downward due to the base 37, so the blade 354 inevitably cuts into the card, and the card can be prevented from being pulled out illegally.

Furthermore, in the present embodiment, the cover member 39 operates so as to come into contact with the card in conjunction with the rotation operation of the first preventing member 33 . Thereby, it is possible to prevent a card-shaped thin plate (for example, a backing plate) from being inserted between the blade 354 and the card, and to more firmly prevent the card from being removed illegally.

One end of the compression spring 36 is connected to a part of the second prevention member 35 , and the other end is movably in contact with the wall 102 of the bracket 100 (see FIG. 6 ). The compression spring 36 applies a pressing force to the second prevention member 35 as described above, and when the end portion 381 of the arm 38 disengages from the groove 351 , the second prevention member 35 is rotated counterclockwise by the pressing force.

FIG. 5 shows the overall structure of the prevention mechanism 30 when viewing the prevention mechanism 30 of FIG. 4 from the opposite direction (the back side of the paper). Therefore, the card is conveyed in the card conveyance direction X1 (from left to right). Here, the cover member 39, the tension spring 40, and the protrusion 335 are demonstrated especially. In the blocking state, the support of the cover member 39 by the protrusion 335 is released, and the cover member 39 moves downward due to the downward tension of the tension spring 40 , and operates so that the tip abuts against the card.

The tension spring 40 applies a pulling force to the cover member 39 downward, and pulls the cover member 39 released from the support by the protrusion 335 downward. The protrusion 335 moves up and down in conjunction with the operation of the first prevention member 33 . Here, when the first preventing member 33 rotates clockwise (counterclockwise in FIG. 4 ), the protrusion 335 moves downward. As a result, the front end of the cover member 39 abuts against the card.

(5) The squint structure of the prevention mechanism

FIG. 6 is an exploded perspective view of the blocking mechanism 30 . Each member constituting the prevention mechanism 30 is provided on the bracket 100 . Protrusions, holes, and the like are formed in the bracket 100 for installing each component, and each component is appropriately accommodated by installing each component at a predetermined position. Here, the operation from the normal state (FIG. 2, FIG. 3) before abnormality detection to the formation prevention state (FIG. 4, FIG. 5) after abnormality detection is described together with the components.

Here, the actuator 31 is fixed in advance at a predetermined position of the bracket 100 , and the movable iron core 311 not shown here is connected to the arm 38 . While the arm 38 is connected to the movable iron core 311, it supports the groove 351 at the end 381 in a normal state, and fixes the second prevention member 35 (FIG. 2, FIG. 3).

If an abnormality is detected, the actuator 31 attracts the movable iron core 311 . When the movable iron core 311 is attracted, one end of the arm 38 connected to the movable iron core 311 is pulled in the direction in which the movable iron core 311 is attracted, and the arm 38 rotates counterclockwise around the rotation shaft 382 . Then, the end portion 381 of the arm 38 is separated from the groove 351, and the second prevention member 35 is no longer supported.

If the second preventing member 35 is no longer supported by the arm 38, it will rotate counterclockwise under the biasing force of the compression spring 36 not shown here, and stop the rotation when the blade 354 comes into contact with the card on the base 37. On the other hand, when the second preventing member 35 rotates, the contact state between the first concave-convex portion 333 and the second concave-convex portion 352 is released and the first preventing member 33 is no longer supported.

When the first stopper 33 is no longer supported by the second stopper 35 , it is pulled by the tension spring 32 and rotates counterclockwise, and stops when the first concave-convex portion 333 comes into contact with the second concave-convex portion 352 .

At this time, the protrusion 335 moves downward in conjunction with the counterclockwise rotation of the first preventing member 33 , and the cover member 39 is no longer supported by the protrusion 335 . When it is no longer supported by the protrusion 335, the cover member 39 is moved downward by the downward force of the tension spring 40, and stops moving when it comes into contact with the card.

In the state where the end 381 of the arm 38 breaks away from the groove 351 and the rotation of the first blocking member 33 and the second blocking member 35 is stopped, if the card is to be pulled out, the second blocking member 35 is further rotated counterclockwise, and the blade 354 Cut into the card. And, no further counterclockwise rotation.

In addition, even if the card is further inserted into the device on the contrary, since the first concave-convex portion 333 engages with the second concave-convex portion 352 and contacts, the first preventing member 33 also prevents the second preventing member 35 from rotating clockwise. Therefore, a blocking state is formed (FIG. 4, FIG. 5).

In addition, even if a foreign object such as a backing plate is inserted between the blade 354 and the card, the front end of the cover member 39 abuts against the card to prevent the insertion of the foreign object. Thus, a stronger blocking state is formed (Fig. 5).

In addition, as the release operation in the case of releasing the blocked state, it is only necessary to press the blocked state release lever 334 as described above. When the blocking state releasing lever 334 is pushed down, the first blocking member 33 rotates clockwise, and the link member 34 transmits the rotation motion to the second blocking member 35, and the second blocking member 35 also rotates clockwise in conjunction with it. In addition, the protrusion 335 moves upward in conjunction with the rotation of the first prevention member 33 , and the cover member 39 also moves upward against the tension of the tension spring 40 in association with the upward movement of the protrusion 335 .

When the groove 351 reaches a predetermined position, the end portion 381 of the arm 38 engages with the groove, whereby the second prevention member 35 is supported by the arm 38 and fixed. Furthermore, by fixing the second prevention member 35 , the first prevention member 33 is supported and fixed by the second prevention member 35 . The cover member 39 supported by the protrusion 335 is also fixed by fixing the first prevention member 33 .

(6) Effects of the present embodiment

As described above, according to the card processing device 1 of this embodiment, the first preventing member 33 and the second preventing member 35 are connected by the link member 34, and the second preventing member 35 is linked with the rotation movement of the first preventing member 33. Rotation is also performed, and the cover member 39 is moved up and down in conjunction with the rotation of the first blocking member 33, so when the blocking state is released, only by pressing the blocking state release lever 334, the first blocking state can be released. Both the first blocking member 33 and the second blocking member 35 rotate to move the cover member 39 upward to release the blocking state.

In addition, when in the blocking state, if the second blocking member 35 rotates counterclockwise, the blade 354 cuts into the card, even if the second blocking member 35 will rotate clockwise, the clockwise movement of the second blocking member 33 is blocked by the first blocking member 33. rotation, so the card can be firmly fixed. Furthermore, since the cover member 39 operates so as to be in contact with the card, foreign matter is prevented from being inserted between the blade 354 and the card, so that the card can be more firmly prevented from being taken out illegally.

Therefore, the card is firmly fixed in the prevented state, and the overall size of the device and the simplification of the release operation are realized, and foreign matter can be prevented from being inserted between the blade 354 and the card.
