If comprised in this way, it will become possible to engage one end part of a card | curd reliably with the tooth space of a toothed belt. Therefore, even if the surface of the card carried out from the card housing part is dirty, or even if the card carried out from the card housing part is deformed or damaged, the card from the card housing part to the transport roller Can be moved reliably.

  In the present invention, the width of the tooth gap in the circumferential direction of the toothed belt formed in an annular shape is preferably equal to or greater than the thickness of one card and smaller than the thickness of two cards. If comprised in this way, it will become possible to move a card | curd one by one from a card accommodating part to a conveyance roller. Therefore, the cards can be conveyed one by one by the conveyance roller. In other words, it is possible to prevent double feeding of cards in which two cards are simultaneously carried out by the transport roller.

  In the present invention, a part of the toothed belt disposed in the card housing portion swells to the outer peripheral side of the toothed belt when one end portion of the card is not engaged with the tooth groove, and the one end portion of the card is When engaged with the tooth gap, it is preferable to bend toward the inner peripheral side of the toothed belt. If comprised in this way, when one end part of the uppermost card | curd (topmost card) of the cards laminated | stacked on a card accommodating part engages with a tooth gap, of the cards laminated | stacked on a card | curd accommodating part One end of the second card from the top becomes difficult to engage with the tooth gap. Therefore, it is possible to prevent the second card from the top from being lifted to the vicinity of the transport roller together with the uppermost card, and as a result, the cards can be transported one by one by the transport roller. become. That is, it becomes possible to prevent double feeding of cards.

And a one-way clutch that cuts off power transmission from the motor to the opposing roller when the transport roller rotates in the direction of rotation. Door is preferable. In this case, for example, when a single card is sandwiched between the transport roller and the opposing roller, the torque limiter cuts power transmission from the motor to the opposing roller, and When two cards are sandwiched between them, power is transmitted from the motor to the opposing roller.

  With this configuration, when a single card is sandwiched between the transport roller and the opposing roller, and the frictional resistance between the card with which the opposing roller abuts and the transport roller increases, a torque limiter is applied. The power transmission from the motor to the opposing roller can be cut off. That is, one card sandwiched between the transport roller and the counter roller by rotating the counter roller in the direction opposite to the rotation direction of the transport roller (that is, rotating the counter roller so as to follow the transport roller). Can be carried out properly. Further, when two cards are sandwiched between the conveying roller and the counter roller and the frictional resistance between the card abutted by the counter roller and the other card becomes small, the torque limiter is not operated. The power can be transmitted from the motor to the opposing roller. That is, by rotating the counter roller in the same direction as the rotation direction of the transport roller (that is, by rotating the counter roller in the card loading direction), it is possible to return the card abutting on the counter roller to the card accommodating portion. Become. Further, it is possible to carry out the card abutting on the carry roller as it is. Therefore, it becomes possible to prevent double feeding of the card.

  The transport roller 11 is disposed on the upper side of the cartridge 3. Specifically, the transport roller 11 is disposed above the rear end side portion of the card 2 accommodated in the cartridge 3 and can come into contact with the upper surface of the rear end side portion of the card 2. The transport roller 11 is fixed to a rotary shaft 20 that is rotatably supported by the frame of the card carry-out device 5. The rotating shaft 20 is disposed so that the axial direction thereof matches the left-right direction. In this embodiment, the two transport rollers 11 are fixed to the rotary shaft 20 with a predetermined interval in the left-right direction. The conveyance roller 11 is a rubber roller in which a rubber ring is fitted on the outer peripheral side of a resin or metal cored bar.

  The facing roller 12 faces the conveying roller 11 from the obliquely rear lower side. Further, the counter roller 12 is fixed to the rotating shaft 21. The rotating shaft 21 is rotatably supported by a shaft holding member (not shown) that is rotatably supported by the frame of the card carry-out device 5. The shaft holding member is urged in one direction of the rotation direction by an urging member (not shown). When the shaft holding member is urged by the urging member, the opposing roller 12 is urged toward the transport roller 11 and can come into contact with the lower surface of the card 2. Moreover, the rotating shaft 21 is arrange | positioned so that the axial direction and the left-right direction may correspond. In this embodiment, similarly to the transport roller 11, the two opposing rollers 12 are fixed to both end sides of the rotating shaft 21 with a predetermined interval left and right. The opposing roller 12 is a rubber roller in which a rubber ring is fitted on the outer peripheral side of a resin or metal cored bar.

  The transport roller 13 is disposed obliquely behind and above the opposing roller 12 and can contact the lower surface of the card 2. The transport roller 13 is fixed to a rotary shaft 22 that is rotatably supported by the frame of the card carry-out device 5.

The pad roller 14 is rotatably supported on the support shaft 23. The support shaft 23 is disposed so that the axial direction thereof matches the left-right direction. In this embodiment, the two pad rollers 14 are rotatably supported by the support shaft 23 with a predetermined interval left and right. The pad roller 14 is a resin roller made of resin.

  The support shaft 23 is held by a holding member (not shown) that is rotatably held by the frame of the card carry-out device 5. A driving source such as a solenoid is connected to the holding member. When this holding member rotates with respect to the frame of the card carry-out device 5 while the pad roller 14 is in contact with the conveying roller 13, the pad roller 14 moves in a direction away from the conveying roller 13. Specifically, the pad roller 14 moves diagonally forward and upward (see FIG. 6B).

  For example, pulleys are fixed to the rotary shafts 20 and 22, and the rotary shafts 20 and 22 are connected to a motor via pulleys, belts, and the like. A pulley 24 is fixed to the rotary shaft 21, and the rotary shaft 21 is connected to a motor to which the rotary shafts 20 and 22 are connected via a pulley 24, a belt, a torque limiter, and the like. The torque limiter for connecting the rotary shaft 21 and the motor intermittently transmits the power transmitted from the motor to the counter roller 12 according to the magnitude of the power transmitted from the motor to the counter roller 12. That is, the torque limiter is configured to slip between the motor and the opposing roller 12 without transmitting torque exceeding a predetermined value from the motor to the opposing roller 12. The pulley 24 is a one-way pulley with a one-way clutch built therein. Specifically, the pulley 24 is a one-way pulley configured to idle in the clockwise direction with respect to the rotating shaft 21. In this embodiment, a power transmission mechanism that transmits the power of the motor to the opposing roller 12 is configured by a torque limiter, a belt, and the like for connecting the pulley 24, the rotating shaft 21, and the motor.

  The counter roller 12 can be rotated in the same direction as the rotation direction of the transport roller 11 by the power of the motor. That is, when the transport roller 11 rotates in the clockwise direction, the motor generates power for rotating the counter roller 12 in the clockwise direction. When the transport roller 11 rotates in the counterclockwise direction, the motor The power for rotating counterclockwise is generated.

  However, since the pulley 24 is a one-way pulley configured to idle in the clockwise direction with respect to the rotating shaft 21, when the conveying roller 11 rotates in the clockwise direction, the pulley 24 is urged toward the conveying roller 11. The roller 12 follows the transport roller 11 and rotates counterclockwise. That is, when the transport roller 11 rotates in the clockwise direction, the pulley 24 cuts power transmission from the motor to the counter roller 12, so that the counter roller 12 follows the transport roller 11 and rotates counterclockwise.

  The torque limiter for connecting the rotating shaft 21 and the motor is such that when the transport roller 11 rotates counterclockwise and the card 2 is not sandwiched between the transport roller 11 and the opposing roller 12, When one card 2 is sandwiched between the transport roller 11 and the opposing roller 12, power transmission from the motor to the opposing roller 12 is cut off, and 2 between the transport roller 11 and the opposing roller 12. When two (or more) cards 2 are sandwiched, power is transmitted from the motor to the opposing roller 12.

  That is, in this torque limiter, the card 2 is not sandwiched between the conveying roller 11 and the opposing roller 12, and the opposing roller 12 contacts the conveying roller 11 and the friction between the opposing roller 12 and the conveying roller 11 is detected. When the resistance increases and when one card 2 is sandwiched between the transport roller 11 and the opposing roller 12, the friction resistance between the card 2 with which the opposing roller 12 abuts and the transport roller 11 is large. When this happens, power transmission from the motor to the opposing roller 12 is cut off. Further, in this torque limiter, two cards 2 are sandwiched between the conveying roller 11 and the opposing roller 12, and the friction resistance between the card 2 with which the opposing roller 12 abuts and the other card 2. When becomes smaller, power is transmitted from the motor to the opposing roller 12.

  Therefore, in this embodiment, when the transport roller 11 rotates counterclockwise and the single card 2 is sandwiched between the transport roller 11 and the counter roller 12, the counter roller 12 is Rotate clockwise following. On the other hand, when two cards 2 are sandwiched between the transport roller 11 and the counter roller 12, the motor power is transmitted to the counter roller 12, and the counter roller 12 rotates in the same counterclockwise direction as the transport roller 11. Rotate.

  Further, the transport roller 13 rotates in the direction opposite to the rotation direction of the transport roller 11 by the power of the motor. That is, when the conveyance roller 11 rotates counterclockwise, the conveyance roller 13 rotates clockwise, and when the conveyance roller 11 rotates clockwise, the conveyance roller 13 rotates counterclockwise.

  In this embodiment, when the transport roller 11 rotates counterclockwise and the transport roller 13 rotates clockwise, the card 2 is transported obliquely rearward and upward from the cartridge 3.

Specifically, the support roller 17 is disposed above the front end side portion of the card 2 accommodated in the cartridge 3 and can come into contact with the upper surface of the front end side portion of the card 2. The support roller 17 is fixed to a rotary shaft 38 that is rotatably supported by the frame of the cartridge 3. The rotary shaft 38 is arranged so that the axial direction thereof coincides with the left-right direction. In this embodiment, the two support rollers 17 are fixed to the rotating shaft 38 with a predetermined interval left and right. The support roller 17 is a rubber roller in which a rubber ring is fitted on the outer peripheral side of a resin or metal cored bar.

  The impeller 18 is fixed to the rotating shaft 38. The impeller 18 is disposed between the support rollers 17 in the left-right direction. The impeller 18 includes a plurality of blades formed of flexible rubber, resin, or the like. The maximum outer diameter of the impeller 18 (the diameter of the tip of the blade) is larger than the outer diameter of the support roller 17. That is, the tip of the blade protrudes outward in the radial direction from the support roller 17. When the impeller 18 rotates counterclockwise, the impeller 18 contacts the front end of the card 2.

  For example, an output side of a torque limiter is attached to the rotary shaft 38. For example, a gear is fixed to the input side of the torque limiter, and the torque limiter is connected to a motor to which the rotary shafts 20 to 22 are connected or a motor provided separately from the motor via a gear or the like. ing. Further, the torque limiter is configured to slip between the motor and the support roller 17 and the impeller 18 without transmitting torque exceeding a predetermined value from the motor to the support roller 17 and the impeller 18. .

  The support roller 17 and the impeller 18 can be rotated in the same direction as the rotation direction of the transport roller 11 by the power of the motor. That is, when the transport roller 11 rotates clockwise, the support roller 17 and the impeller 18 rotate clockwise, and when the transport roller 11 rotates counterclockwise, the support roller 17 and the impeller 18 rotate counterclockwise. Rotate to. The torque limiter attached to the rotation shaft 38 is used when the transport speed of the card 2 by the support roller 17 is higher than the transport speed of the card 2 by the transport roller 11 when the transport roller 11 rotates counterclockwise. Further, the support roller 17 slips so as to follow the conveying speed of the card 2 by the conveying roller 11.

(Card unloading and loading operations)
6 is a diagram for explaining the card 2 carry-out operation and the carry-in operation in the card carry-out device 5 shown in FIG. FIG. 7 is a view for explaining the card 2 carry-in operation in the card carry-out device 5 shown in FIG.

  In the card carry-out device 5 configured as described above, the card 2 is carried out from the cartridge 3 and the card 2 is carried into the cartridge 3 as described below. Hereinafter, the carry-out operation and the carry-in operation of the card 2 will be described in this order.

  When the card 2 is carried out, the card mounting portion of the card lifting / lowering device 6 is raised so that the uppermost card 2 in the cartridge 3 contacts the support roller 17 with a predetermined contact force. As shown in FIG. 6A, the pad roller 14 is disposed at a position in contact with the transport roller 13, and the pad roller 26 is retracted to a position away from the transport roller 25. In this state, when the motor to which the rotary shafts 20 to 22 are connected rotates and the transport roller 11 rotates counterclockwise, the transport roller 13 rotates clockwise, and the support roller 17 and the impeller 18 rotate counterclockwise. The belt 16 rotates in the clockwise direction. In this state, when the transport roller 11 rotates counterclockwise, the facing roller 12 follows the transport roller 11 and rotates clockwise.

  When the belt 16 rotates in the clockwise direction, the rear end portion of the uppermost card 2 accommodated in the cartridge 3 is engaged with the tooth groove of the belt 16 and is lifted up between the conveying roller 11 and the opposing roller 12. At this time, since the blades of the impeller 18 abut against the front end portion of the card 2 and push the card 2 toward the belt 16, the rear end portion of the card 2 is reliably engaged with the tooth groove of the belt 16. Further, since the card 2 is fed by the support roller 17 between the transport roller 11 and the opposing roller 12, the rear end portion of the uppermost card 2 is lifted up between the transport roller 11 and the opposing roller 12. The card 2 is sandwiched between the transport roller 11 and the opposing roller 12 and transported obliquely rearward and upward. At this time, the counter roller 12 rotates in the clockwise direction following the transport roller 11 as described above.

  It should be noted that the rear end portion of the uppermost card 2 is lifted up between the transport roller 11 and the opposing roller 12 in a state where the second card 2 from above is attached to the uppermost card 2, When the card 2 is sandwiched between the transport roller 11 and the counter roller 12, the counter roller 12 rotates in the same counterclockwise direction as the transport roller 11 as described above. That is, the counter roller 12 rotates in the direction in which the card 2 is carried. Therefore, the second card 2 from the top in contact with the counter roller 12 is returned into the cartridge 3.

  The card 2 sandwiched between the transport roller 11 and the counter roller 12 and transported obliquely rearward and upward is then sandwiched between the transport roller 13 and the pad roller 14 so that the rear end of the card 2 is abutted. It is conveyed obliquely rearward and upward until it contacts the contact surface 28a.

  When the rear end of the card 2 comes into contact with the contact surface 28a, the motor to which the rotary shafts 20 to 22 are connected stops, and the transport rollers 11, 13 and the like stop. Thereafter, as shown in FIG. 6B, first, the pad roller 26 moves in a direction approaching the transport roller 25, and then the pad roller 14 is retracted in a direction away from the transport roller 13. Thereafter, the transport roller 25 rotates, and the card 2 sandwiched between the transport roller 25 and the pad roller 26 is transported in the left-right direction by the transport roller 25 and the pad roller 26, and the card 2 is unloaded. End. Note that when the rear end of the card 2 comes into contact with the contact surface 28 a, the front end of the card 2 comes off from between the conveying roller 11 and the opposing roller 12. Further, whether or not the rear end of the card 2 is in contact with the contact surface 28a is detected by a predetermined sensor.

  Here, as described above, when the rear end portion of the card 2 in the cartridge 3 is engaged with the tooth groove of the belt 16, a part of the belt 16 disposed inside the cartridge 3 is on the inner peripheral side of the belt 16. Therefore, when the rear end of the uppermost card 2 in the cartridge 3 engages with the tooth groove of the belt 16, the rear end of the second card 2 from the top engages with the tooth groove of the belt 16. Hard to do. Therefore, even if the belt 16 rotates clockwise, the rear end portion of the second card 2 from the top is hardly lifted by the belt 16. However, when the second card 2 from the top is lifted by the belt 16 under predetermined conditions, the card mounting portion of the card lifting device 6 is lowered as shown in FIG. The conveying roller 11, the supporting roller 17, and the impeller 18 rotate in the clockwise direction, and the belt 16 rotates in the counterclockwise direction. Therefore, the second card 2 from the top after the rear end is lifted by engaging with the tooth groove of the belt 16 is returned into the cartridge 3.

  When the card 2 is carried in, the card mounting portion of the card lifting device 6 is lowered. As shown in FIG. 6B, the pad roller 14 is retracted to a position away from the transport roller 13, and the pad roller 26 is disposed at a position in contact with the transport roller 25. In this state, when the transport roller 25 rotates and the card 2 is transported to a predetermined position in the left-right direction, the transport roller 25 stops. Thereafter, as shown in FIG. 7, the pad roller 14 first moves in a direction approaching the transport roller 13, and then the pad roller 26 is retracted in a direction away from the transport roller 25.

  Thereafter, when the motor to which the rotary shafts 20 to 22 are connected rotates and the transport roller 11 rotates in the clockwise direction, the transport roller 13 rotates in the counterclockwise direction, and the support roller 17 and the impeller 18 rotate in the clockwise direction. The belt 16 rotates counterclockwise. In this state, when the transport roller 11 rotates in the clockwise direction, the counter roller 12 follows the transport roller 11 and rotates in the counterclockwise direction.

  The card 2 is sandwiched between the transport roller 13 and the pad roller 14 and transported diagonally forward and downward, and is then sandwiched between the transport roller 11 and the opposing roller 12 and further transported obliquely forward and downward. The Further, when the card 2 is transported from between the transport roller 11 and the counter roller 12 to a position where the rear end is removed, the rear end of the card 2 is engaged with the tooth groove of the belt 16 and accommodated in the cartridge 3. The card 2 is lowered until it comes into contact with the upper surface of the card 2. When the rear end portion of the card 2 engaged with the tooth groove of the belt 16 is lowered, the card 2 carrying-in operation is finished.

(Main effects of this form)
As described above, in this embodiment, a part of the belt 16 protruding forward from the front ends of the guide members 30 and 31 is disposed inside the upper end side of the cartridge 3 and the belt 16 rotates in the clockwise direction. The rear end portion of the uppermost card 2 accommodated in the cartridge 3 engages with the tooth groove of the belt 16 and is lifted up between the conveying roller 11 and the opposing roller 12. Therefore, in this embodiment, even if the surface of the card 2 carried out from the cartridge 3 is dirty, the rear end portion of the card 2 is engaged with the tooth groove of the belt 16, and the conveying roller 11 and the counter roller 12 are removed from the cartridge 3. It is possible to move the card 2 appropriately between the two. Further, in this embodiment, even if the card 2 carried out from the cartridge 3 is deformed or damaged, the card 2 is conveyed from the cartridge 3 by engaging the rear end portion of the card 2 with the tooth groove of the belt 16. It is possible to appropriately move the card 2 between the roller 11 and the opposing roller 12.

  In particular, in this embodiment, when the card 2 is unloaded from the cartridge 3, the blades of the impeller 18 abut against the front end of the card 2 and push the card 2 toward the belt 16. The rear end portion reliably engages with the tooth groove of the belt 16. Therefore, in this embodiment, even if the surface of the card 2 carried out from the cartridge 3 is dirty, or the card 2 carried out from the cartridge 3 is deformed or damaged, it is transported from the cartridge 3. The card 2 can be reliably moved to between the roller 11 and the opposing roller 12.

  Further, in this embodiment, when the card 2 is carried into the cartridge 3, the belt 16 rotates counterclockwise, and the rear end portion of the card 2 is engaged with the tooth groove of the belt 16. Therefore, in this embodiment, the card 2 can be pushed into the cartridge 3 using the tooth gap of the belt 16. Therefore, in this embodiment, even if the card 2 carried into the cartridge 3 is deformed, the card 2 is prevented from being caught on the upper end side of the cartridge 3 and the cards 2 are stacked in an orderly manner in the cartridge 3. It becomes possible.

  In this embodiment, the width of the tooth gap in the circumferential direction of the belt 16 is equal to or greater than the thickness of one card 2 and smaller than the thickness of two cards 2. Therefore, in this embodiment, the cards 2 can be moved one by one from the cartridge 3 to between the conveying roller 11 and the opposing roller 12. Therefore, in this embodiment, the cards 2 can be conveyed one by one by the conveying roller 11 and the opposing roller 12. That is, in this embodiment, it is possible to prevent double feeding of the card 2 from which the two cards 2 are simultaneously carried out by the transport roller 11 and the counter roller 12.

  In this embodiment, when the rear end portion of the card 2 in the cartridge 3 is engaged with the tooth groove of the belt 16, a part of the belt 16 disposed inside the cartridge 3 is bent toward the inner peripheral side of the belt 16. Therefore, when the rear end portion of the uppermost card 2 in the cartridge 3 is engaged with the tooth groove of the belt 16, the rear end portion of the second card 2 from the top is hardly engaged with the tooth groove of the belt 16. Therefore, in this embodiment, the rear end portion of the second card 2 from the top is hardly lifted by the belt 16, and as a result, the cards 2 can be transported one by one by the transport roller 11. That is, in this embodiment, it is possible to prevent double feeding of the card 2.

  In this embodiment, the counter roller 12 is rotatable in the same direction as the rotation direction of the transport roller 11 by the power of the motor. In addition, the torque limiter for connecting the rotating shaft 21 and the motor is provided between the conveying roller 11 and the opposing roller 12 when the conveying roller 11 rotates counterclockwise (that is, when the card 2 is unloaded). When one card 2 is sandwiched between, the power transmission from the motor to the opposing roller 12 is cut off, and when two cards 2 are sandwiched between the transport roller 11 and the opposing roller 12, The power is transmitted from the motor to the counter roller 12.

  Therefore, as described above, when the card 2 is unloaded, when the single card 2 is sandwiched between the transport roller 11 and the counter roller 12, the counter roller 12 follows the transport roller 11. Rotate. Therefore, in the present embodiment, the card 2 can be appropriately carried out from the cartridge 3. When the two cards 2 are sandwiched between the transport roller 11 and the opposing roller 12, the power of the motor is transmitted to the opposing roller 12, and the opposing roller 12 rotates in the direction in which the card 2 is carried. . Therefore, in this embodiment, the second card 2 from the top contacting the opposing roller 12 can be returned to the cartridge 3, and double feeding of the card 2 can be prevented.

  In this embodiment, the pulley 24 is a one-way pulley configured to idle in the clockwise direction with respect to the rotating shaft 21. Therefore, when the card 2 is carried in, the facing roller 12 follows the transport roller 11 and idles in the card 2 carrying-in direction. Therefore, in this embodiment, the counter roller 12 does not prevent the card 2 from being carried in.

  In this embodiment, the belt 16 is guided from both sides in the left-right direction by the guide members 30 and 31. Therefore, in this embodiment, even if the belt 16 is arranged in a loose state so that a part of the belt 16 arranged inside the cartridge 3 swells to the outer peripheral side of the belt 16, the belt 16 shifts in the left-right direction. Can be suppressed.

  In this embodiment, the belt 16 is rotated by the power of the motor to which the rotary shafts 20 to 22 are coupled. Therefore, in this embodiment, it is possible to simplify the configuration of the card carry-out device 5 as compared with a case where a motor for rotating the belt 16 is separately provided.
