DETAILED DESCRIPTION
[0019] An embodiment of the present invention will be described below with reference to the accompanying drawings.
(Structure of Card Reader)
[0020]
[0021] A card reader 2 in this embodiment is a device for processing a card 3. Specifically, the card reader 2 is a device for reading data recorded in a card 3 and/or recording data to the card 3. The card reader 2 is, for example, mounted and used in a predetermined host apparatuses such as an ATM (Automatic Teller Machine).
[0022] A card 3 is formed in a flat plate shape which is a thin rectangular shape whose thickness is about 0.7-0.8 mm. The card 3 is a plastic card (resin card) in which resin such as vinyl chloride is used as base material, or a metal card in which metal is used as base material. The card 3 is a card in conformity with the international standard and the JIS standard. The card 3 has a built-in IC chip, and one face (specifically, a front face) of the card 3 is formed with an external connection terminal 3b of the IC chip. The external connection terminal 3b is disposed at a position specified in the international standard and the JIS standard. When the card 3 is a plastic card, a magnetic stripe 3c may be formed on the card 3.
[0023] The card reader 2 is formed with a card insertion slot 4 into which a card 3 is inserted. Further, an inside of the card reader 2 is formed with a card conveyance path 5 where the card 3 inserted from the card insertion slot 4 is conveyed. The card reader 2 includes a card conveyance mechanism 6 which conveys a card 3 along the card conveyance path 5. In other words, the card reader 2 is a card conveyance-type card reader. Further, the card reader 2 includes a magnetic head 8 for performing at least one of reading of magnetic data recorded in a card 3 and recording of magnetic data to the card 3, and an IC contact block 9 for communicating data with a built-in IC chip of the card 3.
[0024] In this embodiment, a card 3 is conveyed in the card conveyance path 5 in the X-direction shown in
[0025] In the following descriptions, the X-direction is a front-rear direction, and the Z-direction is an upper-lower direction. Further, in the following descriptions, the X1-direction side in
[0026] In the card reader 2, a card 3 is inserted toward a rear side, and the card 3 is ejected toward a front side. A front end of the card conveyance path 5 is formed with a card insertion slot 4. In the card conveyance path 5, a card 3 is conveyed so that a longitudinal direction of the card 3 formed in a rectangular shape and the front-rear direction are coincided with each other. Further, when the card 3 is inserted into the card insertion slot 4 in a correct direction, a front face of the card 3 (in other words, a face on which an external connection terminal 3b is formed) faces an upper side in the card conveyance path 5, and the external connection terminal 3b is disposed on a rear end side of the card 3.
[0027] The card reader 2 includes, in addition to the card conveyance mechanism 6 and the like, two metal detection mechanisms 10 and 11 for detecting the external connection terminal 3b of the card 3, a pre-head (magnetic head) 12 for detecting magnetic data recorded on the card 3, and a shutter member 13 for closing the card conveyance path 5. Further, the card reader 2 includes an insertion detection mechanism for detecting insertion of a card 3 into the card insertion slot 4. The insertion detection mechanism is, for example, a width detection mechanism which detects an end part of a card 3 in the width direction of the card 3 and thereby detects that the card 3 has been inserted into the card insertion slot 4.
[0028] The card conveyance mechanism 6 includes a plurality of conveyance roller pairs 16 through 18, which are structured to contact with a card 3 to convey the card 3 in a state that the card 3 is sandwiched therebetween. For example, the card conveyance mechanism 6 includes three conveyance roller pairs 16 through 18. Each of the conveyance roller pairs 16 through 18 is structured of a drive roller 19 and a pad roller 20 disposed so as to face the drive roller 19. The drive roller 19 is connected with a motor through a predetermined power transmission mechanism. The pad roller 20 is urged toward the drive roller 19. The drive roller 19 and the pad roller 20 face each other in the upper-lower direction. A card 3 is conveyed in a sandwiched state between the drive roller 19 and the pad roller 20.
[0029] The conveyance roller pairs 16 through 18 are disposed in this order from a front side toward a rear side. In other words, the conveyance roller pair 16 is disposed on the most front side among the three conveyance roller pairs 16 through 18. Distances between the conveyance roller pairs 16 through 18 are set to be slightly shorter than a length in the longitudinal direction of a card 3 which is formed in a rectangular shape. In this embodiment, as shown in
[0030] A magnetic head 8 is, for example, disposed at the same position as the conveyance roller pair 17 in the front-rear direction. The magnetic head 8 is disposed so as to face the card conveyance path 5 from a lower side. An IC contact block 9 is, for example, disposed on a rear end side of the card reader 2. The IC contact block 9 is provided with a plurality of IC contact springs structured to contact with an external connection terminal 3b of a card 3 and perform communication of data. The IC contact block 9 is disposed so as to face the card conveyance path 5 from an upper side. The card reader 2 includes a block moving mechanism which moves the IC contact block 9 between a position where the IC contact springs are capable of contacting with an external connection terminal 3b and a position where the IC contact springs are unable to contact with the external connection terminal 3b.
[0031] The shutter member 13 is movable between a closing position where the card conveyance path 5 is closed and an open position where the card conveyance path 5 is opened. The card reader 2 includes a shutter drive mechanism structured to move the shutter member 13 between the closing position and the open position. The shutter member 13 is disposed on a front side with respect to the conveyance roller pair 16. The pre-head 12 is disposed so as to face the conveyance path 5 from a lower side. The pre-head 12 is disposed on a front side with respect to the shutter member 13. The pre-head 12 functions as detecting that magnetic data are recorded on a card 3 which is inserted into the card insertion slot 4.
[0032] A metal detecting mechanism 10 is a differential type magnetic sensor. The metal detecting mechanism 10 includes, as shown in
[0033] The metal detecting mechanism 10 is disposed on a rear side with respect to the shutter member 13. Further, the metal detecting mechanism 10 is disposed on a front side with respect to a center CL2 of the conveyance roller pair 16 in the front-rear direction. In addition, when a rear end of a card 3 formed with an external connection terminal 3b is sandwiched between the conveyance roller pair 16, the metal detecting mechanism 10 is disposed on a rear side with respect to the external connection terminal 3b of the card 3. Specifically, when a rear end of a card 3 which is formed with an external connection terminal 3b and is inserted into the card insertion slot 4 in a correct direction is sandwiched between the conveyance roller pair 16, the metal detecting mechanism 10 is disposed on a rear side with respect to the external connection terminal 3b (see
[0034] In other words, the metal detecting mechanism 10 is disposed at a position so that the external connection terminal 3b is passed after a card 3 formed with the external connection terminal 3b and inserted into the card insertion slot 4 in a correct direction is moved along the card conveyance path 5 toward a rear side and a rear end of the card 3 is sandwiched between the conveyance roller pair 16. In other words, when a card 3 which is formed with an external connection terminal 3b and is inserted into the card insertion slot 4 in a correct direction is moved along the card conveyance path 5 toward a rear side, after a rear end of the card 3 is sandwiched between the conveyance roller pair 16, the external connection terminal 3b reaches a position where the metal detecting mechanism 10 is disposed in the front-rear direction (see
[0035] A metal detecting mechanism 11 is similarly structured to the metal detecting mechanism 10. In other words, the metal detecting mechanism 11 is a differential type magnetic sensor and includes a core 22, a pair of excitation coils 23 and a detection coil 24. The metal detecting mechanism 11 is disposed on a front side with respect to the shutter member 13. Further, the metal detecting mechanism 11 is disposed on a front side with respect to the pre-head 12. The metal detecting mechanism 11 is disposed so as to face the card conveyance path 5 from an upper side. The metal detecting mechanism 10 and the metal detecting mechanism 11 are disposed at the same position as each other in the upper-lower direction. The metal detecting mechanism 11 in this embodiment is a second metal detecting mechanism.
[0036] When a rear end of a card 3 formed with an external connection terminal 3b and inserted into the card insertion slot 4 in a correct direction reaches a position where the shutter member 13 is disposed in the front-rear direction, the metal detecting mechanism 11 is disposed on a front side with respect to a rear end of the external connection terminal 3b. In other words, when a card 3 which is formed with an external connection terminal 3b and is inserted into the card insertion slot 4 in a correct direction is moved along the card conveyance path 5 toward a rear side, a rear end of the external connection terminal 3b passes through a position where the metal detecting mechanism 11 is disposed in the front-rear direction before a rear end of the card 3 reaches a position where the shutter member 13 is disposed in the front-rear direction.
[0037] In this embodiment, in a standby state before a card 3 is inserted into the card reader 2, the shutter member 13 is disposed at the closing position and closes the card conveyance path 5. On the other hand, for example, when it is detected that a card 3 is inserted into the card insertion slot 4 and, in addition, when the pre-head 12 detects that magnetic data are recorded on the card 3, the shutter member 13 is moved from the closing position to the open position and opens the card conveyance path 5. When the card conveyance path 5 is opened, the card 3 is capable of being taken into an inside of the card reader 2.
[0038] Further, for example, it is detected that a card 3 is inserted into card the insertion slot 4 and, when metal is detected by the metal detecting mechanism 11, the shutter member 13 is moved from the closing position to the open position and opens the card conveyance path 5. In other words, in a case that a card 3 inserted into the card insertion slot 4 is a metal card and, in a case that a card 3 inserted into the card insertion slot 4 is a plastic card, the card 3 is formed with an external connection terminal 3b and, in addition, when the card 3 is inserted into the card insertion slot 4 in a correct direction, metal is detected by the metal detecting mechanism 11 and thus, the shutter member 13 is moved from the closing position to the open position and opens the card conveyance path 5.
[0039] When the card 3 is moved from the shutter member 13 toward a rear side, the card 3 passes a position where the metal detecting mechanism 10 is disposed. In a case that a card 3 inserted into the card insertion slot 4 is a metal card and the card 3 is not formed with an external connection terminal 3b and, in a case that a card 3 is a metal card and, although the card 3 is formed with an external connection terminal 3b, a front face of the card 3 faces a lower side, an output of the metal detecting mechanism 10 varies when a rear end of the card 3 reaches a position where the metal detecting mechanism 10 is disposed but, after that, the output of the metal detecting mechanism 10 hardly varies until a front end of the card 3 passes through the metal detecting mechanism 10.
[0040] On the other hand, the card 3 inserted into the card insertion slot 4 is a metal card and, in a case that the card 3 is formed with an external connection terminal 3b and a front face of the card 3 faces an upper side, when a rear end of the card 3 reaches the position where the metal detecting mechanism 10 is disposed, an output of the metal detecting mechanism 10 varies and, in addition, when the external connection terminal 3b reaches the position where the metal detecting mechanism 10 is disposed, the output of the metal detecting mechanism 10 varies again. Therefore, in this embodiment, even when a card 3 is a metal card, based on detection results of the metal detecting mechanism 10, it can be detected that a front face of a card 3 formed with an external connection terminal 3b faces an upper side.
(Principal Effects in this Embodiment)
[0041] As described above, in this embodiment, when a rear end of a card 3 formed with an external connection terminal 3b is sandwiched between the conveyance roller pair 16 which is disposed on the most front side, the metal detecting mechanism 10 is disposed on a rear side with respect to the external connection terminal 3b. Further, when the card 3 formed with the external connection terminal 3b and inserted into the card insertion slot 4 in a correct direction is moved along the card conveyance path 5 toward a rear side, after a rear end of the card 3 is sandwiched between the conveyance roller pair 16, the external connection terminal 3b reaches the position where the metal detecting mechanism 10 is disposed in the front-rear direction.
[0042] In other words, in this embodiment, when the external connection terminal 3b passes the position where the metal detecting mechanism 10 is disposed in the front-rear direction, at least a rear side portion of the card 3 is sandwiched between the conveyance roller pair 16. Therefore, according to this embodiment, even if a shake (hand shake) of a card 3 occurs when a user manually inserts the card 3 into the card insertion slot 4, in a case that the external connection terminal 3b passes the position where the metal detecting mechanism 10 is disposed in the front-rear direction, variation of a distance between the external connection terminal 3b and the metal detecting mechanism 10 can be suppressed by the conveyance roller pair 16.
[0043] Therefore, according to this embodiment, in a case that a metal card is processed in the card reader 2, variation of an output of the metal detecting mechanism 10 due to variation of a distance between an external connection terminal 3b and the metal detecting mechanism 10 can be suppressed. As a result, in this embodiment, even in a case that a metal card is processed in the card reader 2, deterioration of accuracy for detecting whether a card 3 inserted from the card insertion slot 4 is formed with an external connection terminal 3b or not can be suppressed, and deterioration of accuracy for detecting whether a front face of the card 3 formed with an external connection terminal 3b faces an upper side or not can be suppressed.
[0044] In this embodiment, in a case that a metal card is processed in the card reader 2, it can be detected that a front face of the card 3 formed with an external connection terminal 3b faces an upper side based on a detection result of the metal detecting mechanism 11. However, the metal detecting mechanism 11 is disposed on a front side with respect to the pre-head 12 and is disposed at a position near the card insertion slot 4. Therefore, a distance between the metal detecting mechanism 11 and a card 3 may vary due to a hand shake. When a distance between the metal detecting mechanism 11 and a card 3 varies due to a hand shake, an output of the metal detecting mechanism 11 is varied. Therefore, although an external connection terminal 3b is not formed on the card 3 or, although a front face of the card 3 faces a lower side, an output of the metal detecting mechanism 11 may vary to erroneously detect presence or absence of the external connection terminal 3b of the card 3, and the like.
[0045] In this embodiment, the metal detecting mechanism 10 is disposed on a rear side with respect to the shutter member 13, and the metal detecting mechanism 10 is capable of being disposed on a rear side in the card conveyance path 5. Further, in this embodiment, when a rear end of the card 3 is sandwiched between the conveyance roller pair 16, a half or more portion of the card 3 in the front-rear direction is disposed on a rear side with respect to the card insertion slot 4. Therefore, in this embodiment, when an external connection terminal 3b passes the position where the metal detecting mechanism 10 is disposed in the front-rear direction, a holding margin of a card 3 by a user can be reduced. As a result, when an external connection terminal 3b passes the position where the metal detecting mechanism 10 is disposed in the front-rear direction, a hand shake hardly occurs. Therefore, according to this embodiment, when an external connection terminal 3b passes the position where the metal detecting mechanism 10 is disposed in the front-rear direction, variation of a distance between the external connection terminal 3b and the metal detecting mechanism 10 can be effectively suppressed.
[0046] In this embodiment, the metal detecting mechanism 11 is disposed on a front side with respect to the shutter member 13. Therefore, in this embodiment, in a case that metal is not detected by the metal detecting mechanism 11, the card 3 can be prevented from being taken into a rear side with respect to the shutter member 13.
Other Embodiments
[0047] Although the present invention has been shown and described with reference to a specific embodiment, various changes and modifications will be apparent to those skilled in the art from the teachings herein.
[0048] In the embodiment described above, as shown by the two-dot chain line in
[0049] In the embodiment described above, when a rear end of a card 3 is sandwiched between the conveyance roller pair 16, a half or more portion of the card 3 in the front-rear direction may be disposed on a front side with respect to the card insertion slot 4. Further, in the embodiment described above, the card reader 2 may include no metal detecting mechanism 11. In addition, in the embodiment described above, the card reader 2 may include no magnetic head 8 and no pre-head 12.
Technical Structure
[0050] Embodiments of the present invention may be structured as follows. [0051] (1) A card reader for processing a card which incorporates an IC chip and is formed with an external connection terminal of the IC chip, the card reader including a card insertion slot into which the card is inserted, a card conveyance path in which the card inserted from the card insertion slot is conveyed, a card conveyance mechanism structured to convey the card along the card conveyance path, and a metal detecting mechanism for detecting the external connection terminal. When one side in a conveying direction of the card by the card conveyance mechanism is referred to as a front side and, when the other side in the conveying direction of the card by the card conveyance mechanism is referred to as a rear side, a front side end of the card conveyance path is formed with the card insertion slot. The card conveyance mechanism includes one or more conveyance roller pairs which contact with the card and convey the card in a sandwiching state. In a case that the card conveyance mechanism includes a plurality of the conveyance roller pairs, when the conveyance roller pair which is disposed on the most front side is referred to as a first conveyance roller pair and, in a case that the card conveyance mechanism includes only one conveyance roller pair, when the one conveyance roller pair is referred to as a first conveyance roller pair, the metal detecting mechanism is disposed on a rear side with respect to the external connection terminal of the card when a rear end of the card is sandwiched between the first conveyance roller pair. [0052] (2) The card reader described in the above-mentioned structure (1), where the metal detecting mechanism is disposed on a front side with respect to a center of the first conveyance roller pair in the conveying direction of the card. [0053] (3) The card reader described in the above-mentioned structure (1) or (2), where when the rear end of the card is sandwiched between the first conveyance roller pair, a half or more portion of the card in the conveying direction of the card is disposed on a rear side with respect to the card insertion slot. [0054] (4) The card reader described in one of the above-mentioned structures (1) through (3), further including a shutter member for closing the card conveyance path and a second metal detecting mechanism disposed on a front side with respect to the shutter member, where the metal detecting mechanism is disposed on a rear side with respect to the shutter member.
[0055] In this embodiment, for example, the metal detecting mechanism is disposed on a front side with respect to a center of the first conveyance roller pair in a conveying direction of a card. In this case, various structures for processing the card are easily disposed in an inside of the card reader.
[0056] In this embodiment, it is preferable that when a rear end of the card is sandwiched between the first conveyance roller pair, a half or more portion of the card in the conveying direction of the card is disposed on a rear side with respect to the card insertion slot. According to this structure, in the conveying direction of the card, in a state that an external connection terminal passes a position where the metal detecting mechanism is disposed, a holding margin of the card by a user can be reduced. Therefore, a hand shake hardly occurs when the external connection terminal passes the position where the metal detecting mechanism is disposed in the conveying direction of the card. As a result, when the external connection terminal passes the position where the metal detecting mechanism is disposed in the conveying direction of the card, variation of a distance between the external connection terminal and the metal detecting mechanism can be effectively suppressed.
[0057] In this embodiment, it is preferable that the card reader further includes a shutter member for closing the card conveyance path and a second metal detecting mechanism disposed on a front side with respect to the shutter member, and the metal detecting mechanism is disposed on a rear side with respect to the shutter member. According to this structure, the metal detecting mechanism can be disposed on a rear side in the card conveyance path and thus, in a state that the external connection terminal passes the position where the metal detecting mechanism is disposed in the conveying direction of the card, a holding margin of the card by a user can be reduced. Therefore, when the external connection terminal passes the position where the metal detecting mechanism is disposed in the conveying direction of the card, a hand shake hardly occurs. As a result, in a state that the external connection terminal passes the position where the metal detecting mechanism is disposed in the conveying direction of the card, variation of a distance between the external connection terminal and the metal detecting mechanism can be effectively suppressed. Further, according to this structure, in a case that metal is not detected by the second metal detecting mechanism, the card can be prevented from being taken into a rear side with respect to the shutter member.
[0058] While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.
[0059] The presently disclosed embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
