Description

  The present invention relates to a magnetic card, an IC card, and other card readers that use various cards capable of recording information. More specifically, the present invention forcibly ejects a card when the card is stuck in a conveyance path. The present invention relates to a card reader provided with a forced ejection mechanism.

  If the card inserted into the card reader is a normal one that is not curved, deformed, or contaminated with oil or the like, the card can be transported in the card reader without any problems. However, if a deformed card, a severely dirty card, or a card that is out of the standard size is inserted into the card reader, the card may stay in the transport path, so-called card jam may occur, and the card cannot be processed. Sometimes.

Therefore, in the conventional general card reader, a card forced ejection mechanism is provided independently, assuming that the card has jammed. FIG. 5 schematically shows an example of a card forced ejection mechanism in a conventional card reader. In FIG. 5, three pairs of conveyance rollers 82, 84, 86 are arranged in the card reader with appropriate intervals across the conveyance path 80. The cards inserted from the card insertion slot 88 are sequentially conveyed to the back side by the conveyance roller pairs 82, 84, 86, and predetermined processing, that is, reading and writing of recorded information are performed.
Further, on the lower side of the conveyance path 80 in the figure, a chain 90 is hung on sprockets 92 and 94 arranged before and after the card reader. The chain 90 is a card forcibly ejecting chain, and a forcible ejecting claw 91 is integrally provided in a part of the chain 90. Further, the upper side of the chain 90 is located near the transport path 80 and in parallel with the transport path 80.

  Normally, the chain 90 is not driven, and the claw 91 is retracted from the card conveyance path. When it is detected that the card has jammed, at least one of the sprockets 92 and 94 is rotationally driven in the clockwise direction in FIG. The card is forcedly pushed out toward the card insertion slot 88. (For example, see Patent Document 1.)

JP-A-8-7050

  However, the card reader shown in Patent Document 1 incorporates a forced ejection mechanism that operates independently, and the forced ejection mechanism forcibly ejects the card so that it operates when a jam occurs. Therefore, it is necessary to newly provide a drive source such as a motor and a solenoid. For this reason, there are problems such as an increase in cost and an increase in the size of the card reader.

  In view of the above problems, an object of the present invention is to provide a card reader including a forced ejection mechanism that forcibly ejects a card by using a card transport drive source.

In the present invention, the forced ejection mechanism for forcibly ejecting the card includes a pair of timing pulleys to which the driving force of the drive source is transmitted and the timing belt stretched around these timing pulleys. Thus, the forced ejection mechanism can be operated without requiring a separate drive source, and the card reader can be reduced in size and cost.
Furthermore, since the driving force of the driving source that drives the transport roller is transmitted to the forced discharge mechanism according to the present invention, if the card is removed from the transport roller during transport, the removed card is placed on the timing belt. To move in the direction of rotation. For this reason, retention can be reduced.

  In the present invention, a magnetic head for reading magnetic information of the card is provided in the vicinity of the insertion slot, and the transport roller is disposed in the vicinity of the magnetic head and at a substantially center in the width direction of the transport path. The forcible discharge mechanism is preferably disposed on the opposite side of the magnetic head across the conveyance roller in the width direction of the conveyance path.

As a result, the transport roller for transporting the card is arranged in the vicinity of the magnetic head and at the substantially center in the width direction of the transport path, so that the card can be transported without causing meandering. And stable reading of magnetic information can be performed.
Further, the forcible ejection mechanism can be disposed at a position that does not affect card conveyance.

In the present invention, it is preferable that the pair of timing pulleys are disposed on the insertion port side and the back side, and the timing pulley disposed on the insertion port side is disposed coaxially with the conveying roller.
As a result, the card conveyance speed difference between the conveyance roller and the timing belt constituting the forced ejection mechanism can be reduced, so that stable card conveyance and reading of magnetic information can be performed, and the forced ejection mechanism operates at the same time. However, it does not affect the card transport.
Further, since a connecting member for connecting the transport roller and the timing pulley is not necessary, the number of parts can be reduced.

Furthermore, it is preferable that the timing pulley corresponding to the back side is provided with a pressing roller that presses the card being conveyed toward the timing belt.
In this way, the back side timing pulley is provided with a pressing roller, so that the card to be transported can be sandwiched between the timing belt and the pressing roller, and the mechanism is transported to the back side of the card reader. be able to.

It is characterized by comprising a pair of timing pulleys to which force is transmitted and a timing belt stretched around these timing pulleys.

In the present invention, the forced ejection mechanism for forcibly ejecting the card includes a pair of timing pulleys to which the driving force of the drive source is transmitted and the timing belt stretched around these timing pulleys. Thus, the forced ejection mechanism can be operated without requiring a separate drive source, and the card reader can be reduced in size and cost.
Furthermore, since the driving force of the driving source that drives the transport roller is transmitted to the forced discharge mechanism according to the present invention, if the card is removed from the transport roller during transport, the removed card is placed on the timing belt. To move in the direction of rotation. For this reason, retention can be reduced.

  Hereinafter, the configuration of the present invention will be described in detail based on the best mode shown in the drawings.

  1 and 2 show an example of an embodiment of a card reader to which the present invention is applied. FIG. 1 is a plan view showing a configuration of a card reader according to the present invention. 2 is a cross-sectional view taken along line II of the configuration of the card reader shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along line II-II of the configuration of the card reader shown in FIG. FIG. 4 is a plan view and a side view of the card to be conveyed.

As shown in FIGS. 1, 2, and 3, the card reader 1 has an insertion slot 1 a for inserting the card 4, a transport path 5 for transporting the card 4, and a discharge port for discharging the card 4 from the card reader 1. 1b is configured. Note that a capture box (not shown) is provided at the discharge port 1b so that, for example, a used card can be held in the card reader 1 so as not to be misused by others.
Further, in the transport path 5, a magnetic head 8 that reads magnetic information recorded on the card 4, an IC contact block 16 having an IC contact 18, and a motor 30 as a drive source that drives the transport roller 9. The forced discharge mechanism 10 that forcibly discharges the staying card when the rotation from the motor 30 is transmitted, and the transport roller 9 and the pressure roller 14 that transport the inserted card 4 are disposed.

  In the present embodiment, as shown in FIGS. 1 and 2, the card reader 1 is composed of a main unit 2 and an upper unit 3 provided on the upper part thereof so as to be opened and closed. The transport path 5 is configured by being surrounded by the main unit 2, the upper unit 3, and the side plates 6 and 7. Further, as shown in FIG. 1, the upper surface 5a and the lower surface 5b regulate the thickness of the card 4 inserted into the transport path 5 and force the bent card 4 to be forced.

  The main unit 2 is provided with a magnetic head 8 for reading magnetic information recorded on the magnetic stripe (see FIG. 4) of the card 4. The magnetic head 8 is disposed so as to correspond to the position of the magnetic stripe formed on the card 4, that is, along the side surface 5 d on the insertion port 1 a side in the transport path 5. 8a is exposed in the conveyance path 5 from the opening 5e formed in the lower surface 5b.

  A transport roller 9 is disposed in the vicinity of the magnetic head 8 so as to transport the card 4 inserted into the transport path 5 from the insertion slot 1a. In other words, the conveyance roller 9 is disposed adjacent to the magnetic head 8 in the width direction of the conveyance path 5 and substantially at the center in the width direction of the conveyance path 5. The conveyance roller 9 is composed of a substantially cylindrical roller body 9a made of rubber, and is fixed to a shaft 9b so as to rotate integrally.

  Further, the transport roller 9 rotates to the side plate 7 below the lower surface 5b so that a part of the outer peripheral surface of the roller body 9a protrudes into the transport path 5 from an opening 5f formed in the lower surface 5b of the transport path 5. It is supported freely. Further, the shaft 9 b of the transport roller 9 and the drive shaft of the motor 30 provided in the upper unit 3 are connected via a plurality of gears (gear trains) 20, and the transport roller 9 is driven by the driving force of the motor 30. To rotate.

  A pressing roller 14 is provided inside the upper unit 3 at a position facing the conveying roller 9. The pressing roller 14 includes a substantially cylindrical roller body 14a made of rubber, and is rotatably supported by a shaft 14b.

  The pressing roller 14 is arranged so that its axis is substantially parallel to the axis of the transport roller 9 and the outer peripheral surface of the roller main body 14a is opposed to the outer peripheral surface of the roller main body 9a. It is pivotally supported. The distance between the outer peripheral surface of the roller main body 14a and the outer peripheral surface of the roller main body 9a is set to be smaller than the thickness of the card 4, so that the card 4 inserted into the transport path 5 from the insertion port 1a is inserted into the roller main body 9a. And the roller body 14a.

As shown in FIG. 1, a timing pulley 11 that constitutes a forced discharge mechanism 10 is disposed in the vicinity of the conveyance roller 9.
This forcible ejection mechanism 10 forcibly ejects the card 4 when the driving force of the motor 30 is transmitted and the card 4 stays in the transport path 5, and is a timing pulley arranged on the insertion port 1a side. 11, a timing pulley 12 and a timing belt 13 disposed on the back side.
The timing pulleys 11 and 12 and the timing belt 13 are disposed on the opposite side of the magnetic head 8 with the conveyance roller 9 in the width direction of the conveyance path 5.

The shaft of the timing pulley 11 is arranged coaxially with the shaft 9b of the transport roller 9, and is fixed to the shaft 9b with a screw or an adhesive.
The timing pulley 12 has the same shape and size as the timing pulley 11. The timing pulley 12 has an axis substantially parallel to the axis of the transport roller 9, and is connected to the lower unit 2 near the discharge port 1 b on the back side of the card reader 1 (downstream part of the transport path 5). The shaft is pivotally supported.

  A timing belt 13 is stretched around the timing pulleys 11 and 12 arranged in this way. An opening 5 g is formed in the lower surface 5 b of the conveyance path 5 so as to correspond to the timing belt 13, and a part of the outer peripheral surface of the timing belt 13 is exposed in the conveyance path 5 from this opening 5 g. Further, on the outer peripheral surface of the timing belt 13, the exposed surface 13 a exposed from the opening 5 g into the transport path 5 slightly enters the transport path 5.

Further, in the timing pulley 11 on the insertion port 1a side, the exposed surface 13a of the timing belt 13 is equivalent to the conveying path 5 in a direction substantially perpendicular to the exposing surface 13a rather than the contact surface 9c where the conveying roller 9 contacts the card 4. Or it has been evacuated slightly.
In other words, the position of the back surface of the timing belt 13 that is stretched around the timing pulley 11 and protrudes into the conveyance path 5 is set to be substantially equal to or less than the protruding amount of the outer shape of the conveyance roller 9.

For this reason, the card 4 sandwiched between the transport roller 9 and the pressing roller 14 can be transported in the transport path 5 without being greatly affected by the timing belt 13.
As described above, the timing belt 13 spans the insertion port 1a side and the back side (upstream part and downstream part of the conveyance path 5) of the card reader 1 and is transmitted from the conveyance roller 9 via the timing pulley 11. The rotational force is reliably transmitted to the timing pulley 12 disposed on the back side of the card reader 1 by the timing belt 13.

  Further, in the present embodiment, the position of the back surface of the timing belt 13 protruding into the conveyance path 5 is substantially equal to the protruding amount of the outer shape of the conveyance roller 9. For this reason, the conveyance speed of the conveyance roller 9 and the conveyance speed at the position of the back surface of the timing belt 13 on the timing pulley 11 are substantially the same. Therefore, the card 4 can be transported stably, and there is no adverse effect on the reading of magnetic information with the magnetic head 8 or the like. Note that the back surface of the timing belt 13 is a surface on which a stayed card is placed.

  Further, the back surface of the timing belt 13 is preferably made of a material having a certain amount of frictional resistance in order to reliably convey the staying card. In this embodiment, the timing belt 13 is made of rubber. The timing belt 13 is not limited to rubber.

  Since the timing pulley 11 disposed on the insertion port 1a side is not provided with a pressing roller at an opposing position, the timing pulley 11 cannot sandwich the card 4 inserted through the timing belt 13. It has become.

On the other hand, the pressure roller 15 is provided in the position which opposes the timing pulley 12 arrange | positioned in the back | inner side. The pressing roller 15 includes a substantially cylindrical roller body 15a made of rubber, and is rotatably supported on a shaft 15b.
The pressing roller 15 is arranged so that its axis is substantially parallel to the axis of the conveying roller 9 and the outer peripheral surface of the roller body 15 a faces the outer peripheral surface of the timing pulley 12 via the timing belt 13. It is pivotally supported on the side plate 6 so as to be rotatable.

  Further, the outer peripheral surface of the roller body 15 a is in contact with the timing belt 13, whereby the card 4 is sandwiched between the roller body 15 a and the timing belt 13. That is, the card 4 transported to the back side of the transport path 5 is sandwiched between the pressing roller 15 and the timing belt 13 and can be transported to the discharge port 1b side.

The interval H between the timing pulleys 11 and 12 is provided with a slightly shorter interval than the card length L of the card 4 along the conveyance direction of the card 4.
According to JIS X6302, it is defined that a read guarantee (guaranteed to read the magnetic head) is required from the end of the card to 5 mm. (See FIG. 4.) Thus, in this embodiment, the card connecting interval (interval H with the conveying rollers 9 and 12) is set to the magnetic head in order to prevent a connecting shock to the conveying roller during reading of the magnetic head. Is set to be longer than the read standard length.
Furthermore, in order to prevent the card from staying due to falling between the card connections, the card connection interval is set to a card standard length or less.

  In the present embodiment, the interval H between the timing pulleys 11 and 12 is set as follows. The magnetic head 8 is disposed substantially coaxially with the transport roller 9 for transporting the card 4, and the card 4 is connected to the timing pulley 12 that also functions as the transport roller disposed on the discharge port 1b side. The end position is set to be 5 mm or less from the conveying roller 9 and is set so that the card 4 is surely delivered to the timing pulley 12 and the pressing roller 15 by the remaining slight conveyance.

As shown in FIG. 1, a motor 30 as a drive source for rotating the transport roller 9 is accommodated in the upper unit 3 of the transport path 5 between the insertion port 1 a, the transport roller 9, and the pressing roller 14.
Furthermore, the drive shaft of the motor 30 is connected via a plurality of gears 20, and the conveying roller 9 is rotated by receiving the driving force of the motor 30.

  Further, in the present embodiment, an IC contact block 16 is provided in the upper unit 3 to perform electrical processing, that is, read and write information on an IC chip (not shown) mounted on the card 4. It has been. The IC contact block 16 is mainly composed of a substantially L-shaped support member 17, a plurality of IC contacts 18 made of a conductive spring material, and a contact portion 17 a formed in the rear short part of the support member 17. It has a configuration.

The IC contact block 16 is rotatable by two sets of link mechanisms 19 so as to approach and separate from the card 5 being conveyed.
The tip of the contact portion 17 a protrudes from the conveyance path 5 and can come into contact with the tip of the card 4. After contacting the card 4, the IC contact black 16 is provided so as to approach the transport path 5 as the card 4 is transported to the back side. (Refer to the dotted line in FIG. 2.)
When the card 4 is discharged from the discharge port 1b, the IC contact block 16 is not shown, but the tip of the contact portion 17a is separated from the transfer path 5 to the extent that it does not interfere with the transfer of the card 4. It is like that.
Since the configuration and operation of the IC contact block 16 are well known, description thereof is omitted here.

Next, the operation according to the above configuration will be described.
First, when the card 4 is inserted from the insertion slot 1a and the card 4 is detected by a photosensor near the insertion slot 1a, the motor 30 is moved in the direction in which the card 4 is conveyed into the card reader 1 (direction A in FIG. 1). And the conveyance roller 9 starts to rotate.
When the tip of the card 4 inserted from the insertion slot 1a is inserted between the outer peripheral surface of the roller main body 9a and the outer peripheral surface of the roller main body 14a, the card 4 receives the rotational force of the transport roller 9 and enters the transport path 5. It is captured.

While the card 4 is nipped between the conveyance roller 9 and the pressing roller 14, the magnetic information recorded on the magnetic stripe is read by the magnetic head 5 while being conveyed along the conveyance path 5.
When the card 4 is further conveyed to the inner side of the conveying path 5 by the rotational force in the A direction of the conveying roller 9, the tip of the card 4 eventually presses the contact portion 17 a of the IC contact block 16.
When the front end of the card 4 further presses the contact portion 17a further back, the IC contact block 16 rotates counterclockwise in the figure by the link mechanism, and the IC contact 18 contacts the input / output portion of the IC chip of the card 4. .
Thereby, the information stored in the IC chip is read by the IC contact block 16. Or the information is updated.

After the predetermined processing is performed, the motor 30 and the transport roller 9 rotate in a direction (B direction in FIG. 1) in which the card 4 is transported to the insertion slot 1a side.
Since the above-described operation is well known, detailed description thereof is omitted here.

Next, a case where the card 4 is identified as a used card based on the magnetic information read by the magnetic head 5 and the information read by the IC contact block 16 will be described.
In this case, the card 4 is not ejected from the insertion slot 1 a but is ejected from the ejection slot 1 b provided on the back side of the card reader 1.
Therefore, when the card 4 is identified as a used card, the motor 30 and the transport roller 9 rotate in the A direction.
At this time, since the timing pulley 11 that constitutes the forced discharge mechanism 10 is fixed to the shaft 9b on which the roller body 9a of the transport roller 9 is supported, it rotates in the same direction. Therefore, the rotation is transmitted to the timing pulley 12 disposed on the back side through the timing belt 13 engaged with the timing pulley 11.

The leading end of the card 4 being conveyed on the conveying path 5 while being sandwiched between the conveying roller 9 and the pressing roller 14 is inserted between the timing pulley 12 and the pressing roller 15 via the timing belt 13.
When the conveyance roller 9 further rotates, the rear end of the card 4 is separated from the nipping between the conveyance roller 9 and the pressing roller 14, but the leading end of the card 4 is nipped between the timing pulley 12 and the pressing roller 15. Then, it is further conveyed to the back side of the card reader 1.
Thereafter, when the rotation of the transport roller 9 further proceeds, the card 4 is eventually discharged from the discharge port 1b to the capture box.
When the card 4 is discharged from the discharge port 1b, the IC contact block 16 is further separated from the transport path 5 so that the tip of the contact portion 17a does not disturb the transport of the card 4 each time.

(Forced card ejection)
On the other hand, as shown in FIG. 4, when the card to be transported is a deformed card, a severely dirty card, or a card out of the standard size, when the card is inserted into the card reader 1, There is a case where the card stays, so-called card jam occurs.
That is, after the card inserted from the insertion slot 1a is separated from the nipping between the transport roller 9 and the pressing roller 14, the end of the card may not be nipped between the timing pulley 12 and the pressing roller 15. The card stays in the transport path 5. However, since the driving force (rotation) of the motor 30 is transmitted to the forced discharge mechanism 10, it falls on the timing belt 13 and moves in the rotation direction together with the timing belt 13. Thereafter, the end of the card is sandwiched between the timing pulley 12 and the pressing roller 15 on the rotation direction side, and is discharged from the discharge port 1b.
The rotation direction of the motor 30 may be reversed to the insertion port 1a side, and the staying card may be sandwiched between the transport roller 9 and the pressing roller 14 and discharged from the insertion port 1a.

(Main effects of this embodiment)
In the present embodiment, the card reader 1 is provided with a forced ejection mechanism 10 that forcibly ejects the card 4 along the conveyance direction of the card 4 when the card 4 stays in the transportation path 5. Since the driving force of the motor 30 is transmitted to the pair of timing pulleys 11 and 12 and the timing belt 13 stretched between the timing pulleys 11 and 12, the forced discharge mechanism 10 is newly driven. Therefore, the forced ejection mechanism 10 can be operated without requiring a drive source for the card reader 1, and the card reader 1 can be reduced in size and cost.

  Further, since the driving force of the motor 30 that drives the conveyance roller 9 is transmitted to the forced ejection mechanism 10, if the card 4 is detached from the conveyance roller 9 during conveyance, the removed card is placed on the timing belt 13. And move in the direction of rotation. For this reason, retention can be reduced.

  Further, since the transport roller 9 for transporting the card 4 is disposed in the vicinity of the magnetic head 8 and at substantially the center in the width direction of the transport path 5, the card 4 can be transported without causing meandering. And stable reading of magnetic information can be performed. Further, the forced ejection mechanism 10 can be arranged at a position that does not affect card conveyance.

  A pair of timing pulleys 11 and 12 constituting the forced discharge mechanism 10 are arranged on the insertion port 1a side and the discharge port 1b side, and the timing pulley 11 corresponding to the insertion port 1a side is coaxial with the conveying roller 9. Since the difference in the card conveyance speed between the conveyance roller 9 and the timing pulley 11 can be reduced, the card can be stably conveyed and the magnetic information can be read. It does not affect transportation. In addition, since a connecting member for connecting the transport roller 9 and the timing pulley 11 is not necessary, the number of parts can be reduced.

  Furthermore, since the timing pulley 12 corresponding to the discharge port 1b side is provided with a pressing roller 14 that presses the card 4 being conveyed toward the timing belt 13, the timing pulley 12 on the discharge port 1b side is provided with the pressure roller 14. Since the pressing roller 14 is provided, the conveyed card 4 can be sandwiched between the timing belt 13 and the pressing roller 14 and can be discharged to the capture box on the discharge port 1b side of the card reader 1.

  Further, since the exposed surface 13a of the timing belt 13 is retracted to be equal to or retracted from the conveying path 5 in a direction substantially perpendicular to the exposed surface 13a rather than the contact surface 9c of the conveying roller 9, the rotational force of the conveying roller 9 is increased by the card. 4, the influence of the driving force of the timing belt 13 on the card 4 can be reduced, and the magnetic information can be read by the magnetic head 8 or the card 4 of the magnetic head 8 can be read. Can be stably written.

The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention.
As shown in FIG. 4, the card 4 may be a card C2 (for example, a packed card) shorter than the card length L or a thin card C3 (for example, a prepaid card).

  In the above embodiment, the timing pulley 11 and the transport roller 9 are arranged coaxially. However, the timing pulley 11 and the transport roller 9 are not necessarily arranged coaxially, and the axis of the timing pulley 11 and the axis of the transport roller 9 are substantially parallel. In this case, the shaft of the timing pulley 11 and the shaft 9b of the conveying roller 9 are connected via a connecting member such as a gear, and the rotational force of the conveying roller 9 is transmitted to the timing pulley 11. You can do that.

In the above embodiment, the timing pulley 11 is fixed to the shaft 9b of the conveying roller 9 so that the rotation of the timing pulley 11 and the rotation of the conveying roller 9 are synchronized. You may set so that a rotation period may differ.
In this case, the rotational force of the conveying roller 9 may be transmitted to the timing pulley 11 via a plurality of gears having different numbers of teeth.

In the above embodiment, the interval between the timing pulley 11 and the timing pulley 12 is set to be shorter than the card length L. However, the interval between the timing pulley 11 and the timing pulley 12 is set to be longer than the card length L. The conveyance distance of the card 4 may be increased.
In this case, a pressing roller may be provided so as to face the exposed surface 13a of the timing belt 13 for each section shorter than the card length L.
Further, it is preferable to increase the tension of the timing belt 13 by applying a roller to the inner peripheral surface of the timing belt 13.

In addition, the card 4 discharged from the discharge port 1b is a used card. However, the present invention is not limited to this, and is a collection means when the card user does not want to discharge from the insertion port 1a or the card user forgets to remove the card. May be.
Further, a card issuing device may be provided on the discharge port 1b side, and a new card may be inserted into the card reader 1 from the discharge port 1b.

  In the above embodiment, the card reader 1 in which both the magnetic head 8 and the IC contact 16 are mounted is adopted, but the card reader in which only one of the magnetic head 8 and the IC contact 16 is mounted is provided. In other words, the present invention can be applied to any card reader having a function of transporting a card.
