Description

  The present invention relates to a card processing apparatus that reads or writes information on a card on which information such as a magnetic card or an IC card is recorded.

  The conventional card processing apparatus conveys the card inserted from the insertion slot of the card insertion section into the apparatus by rotating the roller. Then, the card processing device reads information recorded on the card using the reading head, or writes information on the card using the writing head. Thereafter, the card processing device discharges the card from the insertion slot by rotating the roller in the reverse direction.

  By the way, in a card processing device attached to a host device such as an ATM (automated cash transaction processing device), a person who intends to act fraudulently tries to clog the card in the card processing device. Some processing may be applied to the processing apparatus. In this case, when the ATM user inserts the card into the insertion slot of the card processing device, the card is jammed in the card processing device. When such an abnormality occurs, the user leaves the place where the ATM is installed and goes to a place where an attendant is present in order to resolve the abnormality. Then, there arises a problem that a person who tries to act improperly takes out a jammed card in the card processing apparatus using a tool or the like and takes it away, and then misuses the card.

  In order to solve the above-mentioned problems, card processing apparatuses having a blocking mechanism for blocking the card from being taken out from the card insertion portion have been proposed in Patent Documents 1 to 3 listed below. The blocking mechanism includes a rotatable eccentric cam and an actuator that rotates the eccentric cam. When a card jam is detected, the actuator is operated to rotate the eccentric cam, and the outer peripheral portion of the eccentric cam contacts the card, thereby preventing the card from being taken out from the card insertion portion. .

  26 and 27 show details of such a blocking mechanism. (A) of each figure has shown the side view of the prevention mechanism, (B) has shown the top view of the prevention mechanism. In (B), illustration of the card 2, the card insertion portion 3, the shutter 14 and the like in (A) is omitted.

  FIG. 26 shows a state where the solenoid 13 which is an actuator is not driven. The eccentric cam 10 is provided to rotate about the shaft 11. Further, as shown in FIG. 26A, the eccentric cam 10 is eccentric with respect to the shaft 11. The outer periphery 9 on the side facing the card 2 of the eccentric cam 10 is formed in a substantially arc shape. For this reason, the distance from the shaft 11 of the eccentric cam 10 to the outer periphery 9 is not constant. On the outer periphery 9 of the eccentric cam 10, the distance from the shaft 11 is in contact with the outer peripheral portion 9 a having a length L 1 that does not contact the card 2 that is transported along the transport path 5 and the card 2 that is transported along the transport path 5. An outer peripheral portion 9b having a length L2 is included. In the state of FIG. 26A, the outer peripheral portion 9 a faces the transport path 5, but the outer peripheral portion 9 a is not in contact with the card 2. On the other hand, as will be described later, by rotating the eccentric cam 10 about the shaft 11 in the clockwise direction so that the outer peripheral portion 9b is directed toward the conveyance path 5, as shown in FIG. 2 surfaces are contacted.

  A torsion coil spring 12 is attached to the shaft 11. The torsion coil spring 12 applies a force to the eccentric cam 10 so as to rotate the eccentric cam 10 clockwise. This is because the lower end portion of the torsion coil spring 12 is engaged with the eccentric cam 10. On the other hand, the upper end portion of the torsion coil spring 12 is in contact with the wall 34.

  As shown in FIG. 26B, the rod 18 is attached to the tip of the plunger 54 of the solenoid 13. A coil spring 55 is provided around the plunger 54. The coil spring 55 applies a force in a direction away from the solenoid 13 to the rod 18. A support 97 that contacts the upper portion of the eccentric cam 10 and supports the eccentric cam 10 in the posture shown in FIG. 26A is connected to the rod 18. The support 97 includes an arm 84, a roller 87, a coil spring 88, and the like. The arm 84 rotates about the shaft 86. The shaft 86 is fixed to the wall 34 via a member such as a plate or a rod (not shown). A coil spring 88 is provided around the shaft 86. One end of the coil spring 88 is in contact with the claw 90 protruding from the arm 84. The other end of the coil spring 88 is in contact with a claw 89 fixed to the wall 34 via a member such as a plate or a rod (not shown). A pin 83 is provided at the center of the arm 84. The pin 83 is inserted into a groove 85 provided in the rod 18. A roller 87 is provided on the left side of the arm 84. The roller 87 can rotate around the shaft 92. The roller 87 is in contact with the right side surface of the block 91 attached to the upper part of the eccentric cam 10. For this reason, even if the eccentric cam 10 tries to rotate clockwise around the shaft 11 by the elastic force of the torsion coil spring 12, the rotation of the eccentric cam 10 is prevented.

  When the solenoid 13 is driven, the plunger 54 is drawn into the solenoid 13. Then, in FIG. 26B, the groove 85 of the rod 18 moves upward, the end of the groove 85 hits the pin 83, and the pin 83 also moves upward. As a result, the arm 84 rotates clockwise about the shaft 86 in FIG. At this time, the roller 87 rotates around the shaft 92. For this reason, the frictional force generated between the roller 87 and the block 91 is small.

  When the card processing device 1 detects the clogging of the card 2, the solenoid 13 is driven as described above. FIG. 27 shows a state where the solenoid 13 is driven. In FIG. 27B, the plunger 54 and the rod 18 are moved upward. Due to the movement of the groove 85, the pin 83 is moved upward. The movement of the pin 83 causes the arm 84 to rotate clockwise about the shaft 86. Since the roller 87 is retracted from the right side surface of the block 91 to the back surface, the eccentric cam 10 is rotated around the shaft 11 by the elastic force of the torsion coil spring 12, and in FIG. Has moved to. At this time, due to the elastic force of the coil spring 88, the arm 84 tries to rotate counterclockwise about the shaft 86. However, due to the elastic force of the coil spring 88, the back surface of the block 91 and the roller 87 are in contact with each other, thereby preventing the arm 84 from rotating. As shown in FIG. 27A, the eccentric cam 10 rotates clockwise around the shaft 11, so that the outer peripheral portion 9 b of the eccentric cam 10 contacts the surface of the card 2. At this time, a pressing force acts on the surface of the card 2 from the eccentric cam 10.

  When the eccentric cam 10 comes into contact with the surface of the card 2, a large frictional force acts between the card 2 and the outer peripheral portion 9 b of the eccentric cam 10 together with the above pressing force. For this reason, even if a person who tries to act illegally tries to pull out the jammed card 2 from the insertion port 3a of the card insertion part 3 using a tool or the like, it cannot be easily removed.

  In the state of FIG. 27A, it is assumed that a person who intends to cheat tries to pull out the card 2 from the insertion slot 3a with a greater force. In this case, by trying to pull out the card 2 with a large force, the eccentric cam 10 rotates further clockwise about the shaft 11 due to the frictional force between the card 2 and the eccentric cam 10. Then, the outer peripheral portion 9b that is in contact with the card 2 moves in substantially the same direction as the direction in which the card 2 is to be pulled out. This state is shown in FIG.

  In FIG. 28, since the eccentric cam 10 is eccentric with respect to the shaft 11, in FIG. 27A, the outer peripheral portion whose distance L2 ′ from the shaft 11 is longer than the outer peripheral portion 9b in contact with the card 2. 9b 'contacts the card 2. The distance L2 'is longer than the distance L2. As a result, a larger pressing force acts on the surface of the card 2 from the eccentric cam 10, and the frictional force between the eccentric cam 10 and the card 2 is further increased. For this reason, it becomes increasingly difficult to pull out the card 2.

  Even if the card 2 is pushed or pulled from the outside of the card processing apparatus 1 by providing a lock mechanism for locking the position of the eccentric cam 10 with the eccentric cam 10 applying a pressing force to the card 2, the card 2 can be prevented from moving. 29 and 30 are structural diagrams in the case where a locking mechanism is attached to the blocking mechanism. In each figure, (A) shows a side view and (B) shows a front view. In (A) and (B), illustration of the support 97 of the blocking mechanism, the solenoid 13, the coil spring 12, and the like is omitted. Moreover, in (B), illustration of the wall 34, the shutter 14, the card insertion part 3, etc. is abbreviate | omitted. In this example, a tooth portion 108 is formed on the outer periphery 9 of the eccentric cam 10.

  FIG. 29 shows a state where the solenoid 13 is not driven. A stand 130 is attached to the wall 34. A fixture 134 is attached so as to rotate about the axis 138 of the table 130. The fixture 134 fixes the position of the eccentric cam 10 to the position shown in FIG. In FIG. 29B, a claw 137 is provided on the left side of the fixture 134. A claw 135 is provided on the upper side of the fixture 134. One end of a coil spring 131 is attached to the claw 133 on the right side of the fixture 134. The other end of the coil spring 131 is hooked in the hole 132 of the base 130. For this reason, due to the elastic force of the coil spring 131, a force is exerted on the fixture 134 to rotate the fixture 134 counterclockwise about the shaft 138. A left side 139 of the fixture 134 is in contact with the lever 19. For this reason, the rotation of the fixture 134 is stopped in the state shown in FIG. In FIG. 29B, the lever 19 is indicated by hatching.

  When the card processing device detects clogging of the card 2, the solenoid 13 (see FIG. 26) is driven. When the solenoid 13 is driven, the eccentric cam 10 rotates in the clockwise direction around the shaft 11 in FIG. Then, the tooth portion 108 of the outer periphery 9 contacts the card 2. The state at this time is shown in FIG.

  In FIG. 30, when the card 2 is pulled out, the eccentric cam 10 tries to rotate further clockwise due to the frictional force between the tooth portion 108 and the card 2. Accordingly, the tooth portion 108 is further pressed against the card 2 and the card 2 is prevented from being pulled out.

  Since the eccentric cam 10 has rotated clockwise, in FIG. 30A, the lever 19 of the eccentric cam 10 has moved to the upper right. For this reason, as shown in FIG. 30B, the lever 19 is disengaged from the left side 139 of the fixture 134. Therefore, the fixture 134 rotates counterclockwise about the shaft 138 by the elastic force of the coil spring 131. Then, the rotation of the fixture 134 stops at the position where the upper claw 135 and the lever 19 come into contact. As a result, the lever 19 cannot move downward. That is, the eccentric cam 10 is locked.

  In this state, when the card 2 is further inserted from the insertion port 3a, the eccentric cam 10 tends to rotate counterclockwise due to the frictional force between the card 2 and the tooth portion 108. At this time, in FIG. 30A, the lever 19 tends to move to the lower left. However, as shown in FIG. 30B, since the pawl 135 of the fixture 134 and the lever 19 are in contact, the eccentric cam 10 cannot rotate counterclockwise. Thereby, even if the card 2 is pushed from the outside of the card processing apparatus 1, the eccentric cam 10 does not rotate, so the card 2 does not move. On the other hand, when the card 2 is pulled, the eccentric cam 10 rotates clockwise by the frictional force between the card 2 and the tooth portion 108, and the tooth portion 108 is further pressed against the surface of the card 2. For this reason, the card 2 cannot be removed.

  Therefore, even if the card 2 is pushed or pulled from the outside of the card processing apparatus with the tooth portion 108 in contact with the card 2, the card 2 does not move. Thereby, it is possible to prevent the card 2 jammed in the card processing device from being taken away.

  In order to release the locked state of the eccentric cam 10, the claw 137 of the fixture 134 is lifted upward and rotated clockwise in FIG. Then, in FIG. 30A, the lever 19 is pushed down, and the eccentric cam 10 is rotated counterclockwise. Then, the arm 84 (see FIG. 27) of the support 97 is rotated counterclockwise around the shaft 86 by the elastic force of the coil spring 88, so that the roller 87 is on the right side surface of the block 91 of the eccentric cam 10. (See FIG. 26), the position of the eccentric cam 10 is fixed, and the state shown in FIG. 29 is restored.

Japanese Patent No. 4223382 Japanese Patent No. 4346470 Japanese Patent No. 4401212

  In the conventional card processing apparatus described above, as described with reference to FIG. 26, when the pin 83 of the arm 84 is inserted into the groove 85 of the rod 18 and the solenoid 13 is driven, the rod 18 moves and the groove 85 When the end hits the pin 83 and the pin 83 moves together with the rod 18, the arm 84 rotates about the shaft 86.

  26B, the position at which the solenoid 13 pulls the arm 84, that is, the position of the pin 83, is the shaft 86, which is the fulcrum of the arm 84, and the roller 87, which is the point of action of the arm 84. On the line connecting As described above, in the structure in which the point on the line connecting the fulcrum of the arm 84 and the action point is pulled, the place and direction in which the solenoid 13 as the actuator is arranged are restricted, and for example, the position from the position in FIG. ° Solenoid 13 could not be placed at a position rotated to the right. For this reason, there is a problem that the solenoid 13 cannot be disposed at a free position even if the position of the solenoid 13 is changed so as not to obstruct surrounding parts and wiring.

  Further, in the conventional card processing apparatus, when a vibration shock is applied in a state where the solenoid 13 is not driven, the eccentric cam 10 and the support 97 are disengaged (state shown in FIG. 27) and malfunction occurs. In order to prevent this, it is necessary to increase the contact force between the eccentric cam 10 and the support 97. For this reason, the spring force of the torsion coil spring 12 that imparts a biasing force in the clockwise direction to the eccentric cam 10 is increased, and a large load is applied to the roller 87 of the arm 84 from the eccentric cam 10. Therefore, when the eccentric cam 10 is unlocked, the lever 19 must be pushed down against this strong spring force, and the operation is not easy. Moreover, in order to reduce the friction of the action point of the arm 84, it is necessary to provide the roller 87 which plays a role of a bearing, resulting in a problem that the cost is increased.

  In view of the above problems, the present invention can arrange an actuator for driving an eccentric cam without being restricted in place and direction, and can easily unlock the eccentric cam. An object of the present invention is to provide a card processing apparatus capable of reducing the cost.

  A card processing device according to the present invention includes a card insertion portion into which a card on which information is recorded is inserted, an abnormality detection means for detecting an abnormality of the card inserted from the card insertion portion, and the abnormality detection means. And a blocking mechanism for blocking the removal of the card from the card insertion portion when detected. The blocking mechanism includes an eccentric cam, a support, and an actuator. The eccentric cam is rotatably provided and can be displaced to a first position where the eccentric cam is separated from the card and does not apply a pressing force to the card and a second position which contacts the card and applies the pressing force to the card. It has become. The support is rotatably provided, supports the eccentric cam at the first position by engaging with the eccentric cam, and releases the engagement with the eccentric cam by releasing the engagement with the eccentric cam. Displace from the position to the second position. The actuator rotates the support so that the engagement between the support and the eccentric cam is released when the abnormality detection means detects an abnormality.

  In the present invention, the support device includes four arms arranged in a cross shape, and the position of the center of gravity on the first plane including the four arms is the first rotation in the first plane. The center of gravity on a second plane that coincides with the center and that includes the first rotation center and is orthogonal to the first plane has a structure that coincides with the second rotation center in the second plane. ing. One of the four arms is engaged with the eccentric cam, and one of the remaining arms is connected to the actuator.

  According to such a configuration, the actuator is connected to an arbitrary arm (that is, an arm having no action point) other than the arm that engages with the eccentric cam among the four arms. Instead of pulling a point on the line connecting the action points, a point other than the point on the line is pulled. For this reason, the restrictions on the location and direction of the actuator are relaxed, and the degree of freedom in arrangement can be increased.

  In addition, since the support has a structure in which the center of gravity coincides with the center of rotation in both the first plane and the second plane, the support tool is balanced in all of the front-rear direction, the left-right direction, and the up-down direction. No matter what direction the vibration shock is applied, no rotational moment is generated on the support. For this reason, even if a large load is not applied to the support from the eccentric cam, the eccentric cam and the support are not disengaged due to vibration shock, and a malfunction does not occur. Therefore, it is necessary to apply a strong spring force to the eccentric cam. Therefore, the operation of unlocking the eccentric cam becomes easy.

  Furthermore, since the load at the portion (action point) where the support tool and the eccentric cam engage is small, it is not necessary to provide a roller for reducing friction as in the conventional case, and the cost can be reduced.

  In the card processing device according to the present invention, the arm includes a first arm, a second arm extending in a direction opposite to the first arm, a third arm orthogonal to the first and second arms, and the third arm. A fourth arm extending in the opposite direction, the first arm is connected to the actuator, the second arm has a weight that balances the first arm, and the third arm is an actuator relative to the first and second arms. The fourth arm may extend to the opposite side and engage with the eccentric cam, and the fourth arm may have a function of a weight that extends to the same side as the actuator with respect to the first and second arms and balances with the third arm.

  In the card processing device according to the present invention, the eccentric cam includes a cam portion that contacts the card, an engagement portion that engages with the support, and a lever that is operated when releasing the contact between the cam portion and the card. It may be configured as provided.

  The card processing device according to the present invention may further include a lock mechanism for locking the eccentric cam at the second position. This locking mechanism includes a fixture that can rotate in a locking direction, which is a direction approaching the lever of the eccentric cam, and a release direction, which is a direction away from the lever. In a preferred embodiment, the fixture has a locking portion, a first claw portion, and a second claw portion. When the eccentric cam is locked, the engaging portion is engaged with the lever of the eccentric cam when the fixture is rotated in the locking direction along with the movement of the eccentric cam to the second position. When releasing the lock of the eccentric cam, after the fixing tool is rotated in the releasing direction, when the lever is pressed down, the lever presses the first claw portion, so that the fixing tool is locked again. Rotate in the direction. Further, when the lock of the eccentric cam is released and the eccentric cam is in the first position and the fixture is operated in the release direction, the second claw portion comes into contact with the lever and On the other hand, a force in a direction to increase the engagement force between the eccentric cam and the support is applied.

  According to such a configuration, since the eccentric cam is locked in a state of pressing the card, it is possible to more reliably prevent the card from being taken out from the card insertion portion. Further, even if the fixing tool is accidentally operated in the release direction when the eccentric cam is not locked, the engaging force between the eccentric cam and the support tool is applied from the second claw portion to the lever of the eccentric cam. Since the force acting to strengthen the force acts, the engagement between the eccentric cam and the support is not released and the eccentric cam is not locked, and the malfunction of the blocking mechanism is prevented.

  The card processing device according to the present invention may be configured such that a protrusion for pressing the first claw portion of the support is provided on the lever of the eccentric cam.

  According to the present invention, it is possible to arrange an actuator for driving an eccentric cam without being restricted in place or direction, and to easily unlock the eccentric cam, and to reduce the cost. An apparatus can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, the same reference numerals are given to the same portions or corresponding portions.

  First, a schematic structure of a card processing apparatus according to an embodiment of the present invention will be described with reference to FIG. In FIG. 1, the insertion detection sensor 17 detects that the card 2 has been inserted into the insertion slot 3 a of the card insertion portion 3. Information is recorded on the card 2. When the card 2 is a magnetic card, a magnetic stripe is provided on the surface of the card 2 and magnetic information is recorded on the magnetic stripe. When the card 2 is a contact IC card, an IC contact is provided on the surface of the card 2 and an IC chip connected to the IC contact is provided inside the card 2. When the card 2 is a non-contact type IC card, a communication antenna and an IC chip are provided inside the card 2. In the contact IC card and the non-contact IC card, information is recorded on the IC chip. In the following description, a contact IC card is taken as an example of the IC card.

  When the insertion detection sensor 17 detects the insertion of the card 2, the shutter 14 opens. By opening the shutter 14, the card 2 can be conveyed into the card processing apparatus 1. The conveyance path 5 through which the card 2 is conveyed is indicated by a one-dot chain line. In FIG. 26, the shutter 14 is arranged on the upper side of the conveyance path 5, but in the case of FIG. 1, the shutter 14 is arranged on the lower side of the conveyance path 5.

  The conveyance path 5 includes an insertion port 3 a and upper and lower rollers 4. When the motor 25 (FIG. 2) not shown in FIG. 1 is driven, the roller 4 is rotated. When the card 2 inserted from the insertion port 3 a comes into contact with the roller 4, the card 2 is conveyed into the card processing apparatus 1 by the rotating roller 4. The card detection sensors 6, 7, and 8 detect the presence / absence of the card 2 at each position. After the card 2 is inserted, the shutter 14 is closed when the card detection sensor 6 detects the card 2 and does not detect the card 2.

  When the inserted card 2 is a magnetic card, the magnetic head 15 reads the magnetic information on the magnetic card or writes the magnetic information on the magnetic card while the magnetic card is being transported. When the inserted card 2 is an IC card, the card 2 is conveyed to a predetermined position. Then, when the contact head solenoid 28 (FIG. 2) for lowering the IC contact head 16 is driven, the IC contact head 16 is lowered to contact the IC contact of the IC card. The IC contact head 16 reads information from the IC card and writes information to the IC card. When the reading or writing is completed, the contact head solenoid 28 (FIG. 2) stops driving, and the IC contact head 16 is lifted away from the IC contact. When the reading or writing of information on the card 2 is completed, the roller 4 rotates in the reverse direction and the card 2 is conveyed toward the insertion slot 3a. When the card detection sensor 6 detects the card 2 from the state where the card 2 is not detected, the shutter 14 opens. Thereby, the card | curd 2 is conveyed by the roller 4 out of the insertion port 3a.

  An eccentric cam 60 constituting a part of the blocking mechanism is provided in the vicinity of the insertion port 3a. The eccentric cam 60 includes a cam portion 62, a lever 63, and the like, and is rotatable about a shaft 66. The detailed structure of the blocking mechanism including the eccentric cam 60 will be described later.

  As an example of the card abnormality that occurs in the card processing apparatus 1 described above, some kind of work is performed on the insertion port 3a of the card insertion unit 3, and the card 2 is clogged inside the conveyance path 5 when the card 2 is inserted or ejected. Assuming that When the roller 4 is not rotating even though the roller 4 is being rotated, the card processing device 1 detects that the card 2 is jammed at the position of the card detection sensor 6. When the card processing device 1 detects the clogging of the card 2, an eccentric cam solenoid 51 (FIG. 2) described later is driven, and based on this, the eccentric cam 60 rotates clockwise about the shaft 66. . Then, the cam portion 62 of the eccentric cam 60 comes into contact with the surface of the card 2 and a frictional force is generated between the eccentric cam 60 and the card 2, so that the card 2 is prevented from being pulled out from the insertion port 3a. The Detailed operation in this case will be described later.

  Next, the electrical configuration of the card processing apparatus 1 will be described with reference to FIG. In FIG. 2, the CPU 20 controls each part of the card processing device 1 and acquires information from each part. When the card 2 is a magnetic card, the magnetic head 15 reads magnetic information from the magnetic stripe of the card or writes magnetic information to the magnetic stripe. When the card 2 is an IC card, the IC contact head 16 comes in contact with the IC contact of the card to read information from the IC chip or write information to the IC chip.

  The motor 25 is mechanically connected to the roller 4 (FIG. 1). When the motor 25 is driven, the roller 4 rotates. The rotary encoder 26 is an example of an abnormality detection unit in the present invention, and detects the number of rotations of the motor 25. The card detection sensors 6, 7, and 8 detect whether or not the card 2 is present at a predetermined position on the transport path 5 (FIG. 1). The insertion detection sensor 17 detects whether or not the card 2 is present in the insertion slot 3a. Each sensor 6, 7, 8, 17 switches from the OFF state to the ON state when the presence of the card 2 is detected. The shutter solenoid 27 is a solenoid for opening and closing the shutter 14 (FIG. 1). The eccentric cam solenoid 51 is a solenoid for rotating the eccentric cam 60. The contact head solenoid 28 is a solenoid for moving the IC contact head 16 up and down.

  The ROM 21 stores an operation program for the CPU 20. The RAM 22 temporarily stores control parameters for controlling each part and information acquired from each part such as the magnetic head 15 and the IC contact head 16. Further, the RAM 22 temporarily stores information to be written on the card by the magnetic head 15 or the IC contact head 16. The communication unit 24 communicates with the host device. As an example of the host device, there is an ATM in which the card processing device 1 is mounted. The communication unit 24 transmits information read from the card 2, failure information indicating that the card 2 is jammed, and the like to the host device. In addition, the communication unit 24 receives information to be written on the card 2 and type information of the processing target card 2 from the host device.

  Next, the detailed structure of the card processing apparatus 1 will be described with reference to the drawings, focusing on the blocking mechanism and the locking mechanism.

  FIG. 3 shows a structure in the vicinity of the card insertion portion 3 and is shown with the upper wall of the insertion slot 3a removed for convenience. Further, illustration of the insertion detection sensor 17 in FIG. 1 is omitted. The card insertion part 3 is formed of a block of a resin molded product, and is provided on the front surface of the card processing apparatus 1 as shown in FIG. The card 2 is inserted into the insertion slot 3a formed in the card insertion portion 3 in the direction of the arrow in FIG. A wall portion 40 is provided behind the card insertion portion 3. A blocking mechanism 100 is disposed on the rear surface side of the wall portion 40, and a lock mechanism 200 is disposed on the front surface side of the wall portion 40.

  FIG. 4 shows the detailed structure of the blocking mechanism 100 and the locking mechanism 200. (A) is a plan view, (B) is a perspective view, (C) is a front view, and (D) is a side view. In FIG. 4, the illustration of the wall 40 in FIG. 3 is omitted.

  The blocking mechanism 100 includes an eccentric cam 60, a support tool 53, and an eccentric cam solenoid 51. The eccentric cam solenoid 51 is an embodiment of the actuator according to the present invention.

  The eccentric cam 60 is provided so as to be rotatable about a shaft 66 (FIG. 4D), and is formed integrally with the base 61, the cam part 62 attached to the base 61, and the base 61. The lever 63 and the engaging part 64 fixed to the base part 61 are provided. The base part 61, the cam part 62, and the lever 63 are made of metal, and the engaging part 64 is made of resin. A tooth portion 65 is formed on the cam portion 62. The shaft 66 is fixed to a frame (not shown). Although not shown in FIG. 4, the eccentric cam 60 is provided with a torsion coil spring (reference numeral 69 in FIG. 8B). By this spring, a clockwise direction around the shaft 66 is provided. The urging force acts on the eccentric cam 60.

  5A and 5B show the eccentric cam 60, where FIG. 5A is a plan view, FIG. 5B is a front view, and FIG. 5C is a side view. Similar to the eccentric cam 10 of FIG. 26, the distance from the shaft 66 to the outer periphery of the cam portion 62 in the eccentric cam 60 is not equal, and the shaft 66 is eccentric with respect to the outer periphery of the cam portion 62. As shown in FIG. 5C, a protrusion 67 protruding downward is integrally provided near the tip of the lever 63. An E ring 68 is attached to the end of the shaft 66.

  As will be described later, the eccentric cam 60 rotates about the shaft 66 so that the cam portion 62 is separated from the card 2 (the position in FIG. 8D), and the cam portion 62 contacts the card 2. The position can be displaced to the position (the position shown in FIG. 10D).

  Returning to FIG. 4, the support tool 53 will be described. As shown in FIGS. 4A and 4B, the support 53 includes four arms 53a to 53d arranged in a cross shape. These arms 53a to 53d are integrally formed of resin. The support 53 is supported by the shaft 57 and is rotatable about the shaft 57. The shaft 57 is fixed to a frame (not shown).

  Of the four arms 53a to 53d, the first arm 53a is connected via a plunger 58 (FIG. 4C) and a pin 52 (FIG. 4A) of the eccentric cam solenoid 51. The second arm 53b extends in the opposite direction to the first arm 53a and has a weight 56 that balances with the first arm 53a. Here, the weight 56 is made of a columnar metal and is attached to a cylindrical portion formed at the end of the second arm 53b. The third arm 53c orthogonal to the first and second arms 53a, 53b extends to the opposite side of the eccentric cam solenoid 51 with respect to the arms 53a, 53b, and the tip portion is engaged with the eccentric cam 60. It engages with a notch 64 a formed in the portion 64. The fourth arm 53d extending in the direction opposite to the third arm 53c extends to the same side as the eccentric cam solenoid 51 with respect to the first and second arms 53a and 53b, and functions as a weight that balances with the third arm 53c. Have.

  The support member 53 is urged counterclockwise around the shaft 57 in FIG. 4A by a coil spring 59 interposed between the support cam 53 and the eccentric cam solenoid 51. As will be described later, when the support member 53 is rotated about the shaft 57, the third arm 53c is located between the position where it is engaged with the eccentric cam 60 (the position shown in FIG. 8A) and the eccentric cam 60. It can be displaced to a disengaged position (position shown in FIG. 10A).

  FIG. 6 shows a front sectional view of the support 53. The end of the first arm 53a is connected to the plunger 58 of the eccentric cam solenoid 51 via the pin 52, and receives a load from the coil spring 59, so that a corresponding load is applied to the first arm 53a. . Therefore, in order to balance the first arm 53a, a weight 56 is provided at the end of the second arm 53b. Reference numeral 81 denotes a flange portion of the shaft 57, and reference numeral 82 denotes an E-ring attached to an end portion of the shaft 57.

  Next, the balance of the support tool 53 will be described with reference to FIG. Since FIG. 7 is a diagram for explaining the principle of balance, the support 53 is schematically illustrated. (A) is a plan view and (B) is a front view.

  In FIG. 7A, the X coordinate and the Y coordinate are set in the direction of the drawing, and the plane including the four arms 53a to 53d is defined as the XY plane. This XY plane corresponds to the first plane in the present invention. At this time, the center of rotation when the support 53 is about to rotate in the direction of arrow a on the XY plane is the axis of the shaft 57. This rotation center corresponds to the first rotation center in the present invention.

  Here, as described above, with respect to the first arm 53a and the second arm 53b, a weight 56 that balances the first arm 53a is provided on the second arm 53b. As for the third arm 53c and the fourth arm 53d, the fourth arm 53d has a function of a weight that balances with the third arm 53c. Therefore, on the XY plane, the position of the center of gravity of the support 53 coincides with the rotation center (the axis of the shaft 57).

  On the other hand, in FIG. 7B, the Z coordinate is set in the direction of the drawing, and the plane including the axis 57 and orthogonal to the XY plane is defined as the XZ plane. This XZ plane corresponds to the second plane in the present invention. At this time, the center of rotation when the support 53 is about to rotate in the direction of arrow b on the XZ plane is a point P on the axis of the shaft 57.

  Here, the arms 53a to 53d, the weight 56, the flange portion 81, the E ring 82, etc., so that the position of the center of gravity of the support member 53 on the XZ plane coincides with the rotation center (point P) on the same plane. The shape and weight are designed.

  Thus, in the present embodiment, the center of gravity position of the support tool 53 matches the rotation center on the XY plane, and the center of gravity position of the support tool 53 also matches the rotation center on the XZ plane. For this reason, no rotational moment is generated in the support 53 even if vibration or impact is applied in any of the front and rear, left and right, and top and bottom directions.

  Returning to FIG. 4 again, the lock mechanism 200 will be described next. As shown in FIG. 4B, the lock mechanism 200 includes a fixture 70, a shaft 78 that rotatably supports the fixture 70, and a torsion coil spring 79 that applies elastic force to the fixture 70. And a frame 80 to which a shaft 78 is fixed.

  The fixture 70 includes a first portion 71 formed in an arcuate shape, a second portion 72 extending from the first portion 71 in parallel with the shaft 78, and a third portion 73 extending perpendicularly from the second portion 72. Have. The first portion 71 includes an operation piece 74 for rotating the fixing tool 70 when unlocked, a locking portion 75 for locking the lever 63 of the eccentric cam 60, and a claw portion 77 that can come into contact with the lever 63. Is provided. The third portion 73 is provided with a claw portion 76 that is pushed by the protrusion 67 (FIG. 5C) of the lever 63. The claw portion 76 corresponds to the first claw portion in the present invention, and the claw portion 77 corresponds to the second claw portion in the present invention.

  The first portion 71 and the third portion 73 are inserted through a shaft 78 fixed to the frame 80. As a result, the fixing tool 70 has a locking direction (counterclockwise direction) that is a direction approaching the lever 63 of the eccentric cam 60 around the shaft 78 and a release direction (clockwise direction) that is a direction away from the lever 63. Can be rotated. The locking portion 75 of the first portion 71 is formed with gear-like irregularities. The torsion coil spring 79 has one end supported by the frame 80 and the other end connected to a pin 81 (FIG. 4A) fixed to the first portion 71. The torsion coil spring 79 biases the fixture 70 counterclockwise around the shaft 78 in FIG. 4C.

  Next, operations of the blocking mechanism 100 and the locking mechanism 200 will be described with reference to FIGS.

  At normal time (standby), the blocking mechanism 100 is in the state shown in FIG. 8A is a plan view, FIG. 8B is a perspective view, FIG. 8C is a front view, and FIG. 8D is a side view. In FIG. 8, the lock mechanism 200 is not shown.

  In the state of FIG. 8, the eccentric cam solenoid 51 is not operated, and the tip of the third arm 53 c of the support 53 is engaged with the notch 64 a formed in the engaging portion 64 of the eccentric cam 60. . The support member 53 receives the elastic force of the coil spring 59 and is biased counterclockwise about the shaft 57 in FIG. 8A, so that the above engagement state is maintained.

  On the other hand, the eccentric cam 60 receives a clockwise force about the shaft 66 by the torsion coil spring 69 (FIG. 8B). As described above, the tip of the third arm 53c is connected to the eccentric cam. Since it is engaged with the 60 engaging portions 64, it cannot be rotated clockwise. For this reason, the eccentric cam 60 exists in the position shown to FIG. 8 (D). This position is a position where the cam portion 62 is separated from the card 2 and does not apply a pressing force to the card 2, and corresponds to the first position in the present invention.

  FIG. 9 shows a state of the lock mechanism 200 when the blocking mechanism 100 is in the state of FIG. 9A is a plan view, FIG. 9B is a perspective view, FIG. 9C is a front view, and FIG. 9D is a side view. In FIG. 9, the eccentric cam solenoid 51 and the support 53 are not shown.

  In the state of FIG. 9, the fixing tool 70 is urged counterclockwise about the shaft 78 by the torsion coil spring 79, and the first portion 71 contacts the side surface of the lever 63 of the eccentric cam 60. ing. For this reason, the fixture 70 does not rotate further counterclockwise.

  When the clogging of the card 2 is detected by a method described later, the blocking mechanism 100 is in the state shown in FIG. 10, (A) is a plan view, (B) is a perspective view, (C) is a front view, and (D) is a side view. In FIG. 10, the lock mechanism 200 is not shown.

  In the state of FIG. 10, the eccentric cam solenoid 51 is activated, and the first arm 53 a of the support 53 is pulled by the plunger 58 of the eccentric cam solenoid 51 via the pin 52. Accordingly, the support member 53 rotates in the clockwise direction about the shaft 57 in FIG. 10A against the elastic force of the coil spring 59. For this reason, the tip of the third arm 53c is detached from the notch 64a formed in the engaging portion 64 of the eccentric cam 60, and the engagement between the third arm 53c and the eccentric cam 60 is released.

  As a result, the eccentric cam 60 is rotated clockwise about the shaft 66 by the elastic force of the torsion coil spring 69 and displaced to the position shown in FIG. This position is a position where the cam portion 62 comes into contact with the card 2 and applies a pressing force to the card 2, and corresponds to the second position in the present invention.

  In this state, as in the case of FIG. 27, the more the card 2 is pulled out from the insertion slot 3a, the stronger the pressing force of the cam portion 62 against the card 2 becomes, and the more difficult the card 2 is pulled out. In particular, since the tooth portion 65 formed on the cam portion 62 bites into the surface of the card 2, it becomes more difficult to pull out the card 2 from the insertion port 3a.

  FIG. 11 shows the state of the locking mechanism 200 when the blocking mechanism 100 is in the state of FIG. 11A is a plan view, FIG. 11B is a perspective view, FIG. 11C is a front view, and FIG. 11D is a side view. In FIG. 11, the eccentric cam solenoid 51 and the support 53 are not shown.

  As the eccentric cam 60 is displaced to the position shown in FIG. 10D, the lever 63 jumps upward. For this reason, the fixture 70 of the lock mechanism 200 is further rotated counterclockwise (lock direction) from the position of FIG. 9C by the biasing force of the torsion coil spring 79, and is then moved to FIG. As shown, it stops at a position where it contacts the lever 63. At this time, the rotation of the fixing tool 70 is also restricted by the pin 81 fixed to the fixing tool 70 coming into contact with the end of the guide groove 80 a formed in the frame 80.

  In this state, a part of the locking portion 75 of the fixture 70 is locked with the lever 63. Therefore, it is impossible to release the contact between the cam portion 62 of the eccentric cam 60 and the card 2 by pushing down the lever 63, and the eccentric cam 60 is locked at the position shown in FIG. Thereby, it can prevent more reliably that the card | curd 2 is pulled out from the insertion port 3a. In the state of FIG. 11, there may be a slight gap between the locking portion 75 and the lever 63. The “locking” as used in the present invention includes such a case.

  To release the lock of the eccentric cam 60, the following operation is performed. 12 and 13 are diagrams for explaining the operation in this case. In each figure, (A) is a plan view, (B) is a perspective view, (C) is a front view, and (D) is a side view. In each figure, the eccentric cam solenoid 51 and the support 53 are not shown.

  First, as shown in FIG. 12, the operation piece 74 of the fixture 70 is gripped, and the fixture 70 is rotated in the clockwise direction (release direction) about the shaft 78. This rotation is performed halfway against the spring force of the torsion coil spring 79, but when the fixture 70 is rotated to some extent, the torsion coil spring 79 snaps and the spring The force acts to rotate the fixture 70 in the clockwise direction. For this reason, after the fixing tool 70 is rotated to the position shown in FIG. 12C, the fixing tool 70 is rotated in the counterclockwise direction (locking direction) even if the gripping of the operation piece 74 is released. Without stopping at this position. In addition, in the position of FIG.12 (C), when the pin 81 of the fixing tool 70 contact | abuts to the edge part of the guide groove 80a of the flame | frame 80, the further rotation of the fixing tool 70 is controlled.

  Next, as shown in FIG. 13, the lever 63 of the eccentric cam 60 is pushed down. At this time, since the engaging portion 75 of the fixing tool 70 is retracted to the side of the lever 63, the lever 63 can be pushed down without being obstructed by the fixing tool 70. When the lever 63 is pushed down, the eccentric cam 60 rotates counterclockwise about the shaft 66. For this reason, the cam portion 62 moves away from the card 2 as shown in FIG.

  When the lever 63 is further pushed down from the state of FIG. 13, the claw portion 76 formed on the third portion 73 of the fixture 70 is pushed by the projection 67 provided on the lever 63, so that the fixture 70 rotates the shaft 78. As a center, rotation starts in the counterclockwise direction (lock direction). When the lever 63 is pushed down to the end, the fixture 70 returns to the position shown in FIG.

  As described above, since the protrusion 63 is provided on the lever 63 and the claw portion 76 is pushed by the protrusion 67, the amount of depression of the lever 63 when the fixing device 70 is returned to the original position can be reduced. Improves.

  On the other hand, when the eccentric cam 60 rotates counterclockwise by the depression of the lever 63, the tip of the third arm 53 c of the support member 53 is inserted into the notch 64 a of the engaging portion 64 of the eccentric cam 60. The support 53 is returned to the position shown in FIG.

  By the operation as described above, the lock of the eccentric cam 60 is released, the blocking mechanism 100 returns to the state of FIG. 8, and the lock mechanism 200 returns to the state of FIG.

  According to the embodiment described above, the eccentric cam solenoid 51 can be connected to an arbitrary arm other than the third arm 53c engaged with the eccentric cam 60 among the four arms 53a to 53d. In this embodiment, the eccentric cam solenoid 51 is connected to the first arm 53a, but the eccentric cam solenoid 51 may be connected to the second arm 53b or the fourth arm 53d. For example, when the eccentric cam solenoid 51 is connected to the second arm 53b, the weight 56 is provided on the first arm 53a.

  Since the arm other than the third arm 53c is an arm that does not have an action point (a portion that engages with the eccentric cam 60), when the eccentric cam solenoid 51 is connected to these arms, the solenoid 51 becomes the fulcrum of the arm. The part other than the point on the line connecting the (axis 57) and the action point is pulled. For this reason, compared with the conventional case where the point on the line connecting the fulcrum and the action point of the arm is pulled, the restriction on the location and direction of the eccentric cam solenoid 51 is relaxed, and the degree of freedom of the arrangement is increased. be able to.

  Further, in the present embodiment, as described with reference to FIG. 7, no rotational moment is generated in the support 53 even if vibration or impact is applied in any direction, so that a large load is applied to the support 57 from the eccentric cam 60. Even if it is not, there is no possibility that the eccentric cam 60 and the support member 57 are disengaged due to vibration shock and the blocking mechanism 100 malfunctions. Therefore, since it is not necessary to increase the spring force of the torsion coil spring 69 (FIG. 8B), the biasing force applied to the eccentric cam 60 can be small. As a result, the force for pushing down the lever 63 of the eccentric cam 60 can be reduced, and the unlocking operation of the eccentric cam 60 is facilitated.

  Further, in this embodiment, since the load of the engaging portion (action point) between the support tool 57 and the eccentric cam 60 is small, a roller 87 (FIG. 26) for reducing friction as in the prior art is provided on the support tool 57. There is no need to engage the tip of the third arm 53c with the notch 64a provided in the engaging portion 64 of the eccentric cam 60. Thus, the cost can be reduced by omitting the roller.

  In the present embodiment, the lock mechanism 200 is also devised. The conventional lock mechanism has a problem that when the eccentric cam is not locked and the fixing tool is erroneously operated in the release direction, the eccentric cam rotates and malfunctions (becomes locked). Specifically, in FIG. 29 (unlocked state), when the claw 137 of the fixture 134 is strongly pressed upward, the claw 137 contacts the lever 19 and the eccentric cam 10 rotates clockwise about the shaft 11. Receive the power of When this force is strong, the engagement state between the eccentric cam 10 and the arm 84 shifts from the state shown in FIG. 26 to the state shown in FIG. 27, and the eccentric cam 10 rotates in the clockwise direction to enter the locked state.

  On the other hand, in the lock mechanism 200 of the present embodiment, when the eccentric 70 is accidentally operated in the release direction (clockwise direction) in the state shown in FIG. 77 abuts on the lever 63. In this case, since the claw portion 77 has a tapered shape, the tapered surface of the claw portion 77 is in line contact with the edge of the lower surface of the lever 63. When the fixing tool 70 is still operated in the releasing direction, a strong force is applied from the claw portion 77 to the lever 63, and this force acts to increase the engagement force between the eccentric cam 60 and the support tool 53. .

  That is, as a result of the taper surface of the claw portion 77 pushing the edge of the lower surface of the lever 63, the lever 63 receives a leftward force from the claw portion 77 in addition to the upward force in FIG. Due to this leftward force, the lever 63 tends to be displaced to the left in FIG. Along with this, the engaging portion 64 also tends to be displaced to the left side, that is, the direction opposite to the direction in which the engagement with the third arm 53c is disengaged, so that the third arm 53c and the engaging portion 64 are more strongly engaged. Will do. As a result, even if the fixture 70 is operated in the release direction, the eccentric cam 60 will not malfunction and become locked (FIG. 10).

  Next, a process from when the card processing apparatus 1 reads and writes information to the inserted card 2 until the card 2 is ejected will be described. In addition, processing when the card 2 is jammed when the card 2 is inserted or ejected will be described.

  FIG. 14 is a flowchart showing an outline of card processing in the card processing apparatus 1. In step S <b> 1, the CPU 20 receives the type of the card 2 from the host device via the communication unit 24. Here, as a type of the card 2, a magnetic card and a contact IC card are assumed. Next, in step S2, the CPU 20 determines whether or not the type of the received card 2 is a magnetic card. If it is determined that the card is a magnetic card, in step S3, the CPU 20 performs a magnetic card take-in process and a magnetic information read process from the magnetic card. Subsequently, in step S4, the CPU 20 performs a magnetic information writing process on the magnetic card. In step S5, the CPU 20 performs a card 2 ejection process. Details of the card processing in steps S3, S4, and S5 will be described later.

  On the other hand, when it is determined in step S2 that the type of the received card 2 is not a magnetic card, in step S6, the CPU 20 determines whether or not the type of the received card 2 is an IC card. If it is determined that the card is an IC card, in step S7, the CPU 20 performs an IC card take-in process, an information read process from the IC card, and an information write process to the IC card. Thereafter, in step S5, the CPU 20 performs a card 2 ejection process. Details of the card processing in step S7 will be described later.

  If it is determined in step S6 that the type of the received card 2 is not an IC card, the CPU 20 proceeds to step S5 without performing each process in step S7, and performs a card 2 ejection process. This is because the inserted card is neither an assumed magnetic card nor an IC card, and therefore card processing cannot be performed.

  FIG. 15 is a flowchart showing details of the magnetic card taking process and the magnetic card reading process in step S3 of FIG. In step S20, the CPU 20 determines whether or not the insertion detection sensor 17 has detected insertion of the card 2 (magnetic card) into the insertion slot 3a. FIG. 20 shows a state where the card 2 is inserted into the insertion slot 3a. In this state, since the tip of the card 2 has not reached the position of the insertion detection sensor 17, the shutter 14 is closed.

  When the insertion detection sensor 17 detects the insertion of the card 2, the CPU 20 proceeds to the next step S21. In step S21, the CPU 20 drives the shutter solenoid 27. Thereby, as shown in FIG. 21, the shutter 14 opens the conveyance path 5. FIG. 21 shows a state in which the card 2 is inserted into the card processing apparatus 1. In step S <b> 22 of FIG. 15, the CPU 20 starts normal rotation driving of the motor 25. When the motor 25 is driven to rotate forward, the rollers 4 connected to the motor 25 rotate in a direction (forward rotation direction) in which the card 2 is conveyed into the card processing apparatus 1. As a result, the card 2 is conveyed to the right along the conveyance path 5 at a constant speed by each roller 4 from the time when the card 2 is inserted until the leading end contacts the roller 4 closest to the insertion port 3a. In the process of transporting the card 2, the magnetic head 15 reads the magnetic information recorded on the card 2.

  The CPU 20 keeps the rotation speed of the motor 25 constant by performing feedback control based on the rotation speed of the motor 25 obtained from the output of the rotary encoder 26. Until the drive of the motor 25 is stopped in step S28 of FIG. 15, the CPU 20 controls the motor 25 to continuously rotate forward at a constant speed.

  In step S <b> 23, the CPU 20 determines whether or not the rotary encoder 26 regularly outputs the rotation speed of the motor 25. For example, in response to the CPU 20 sending a drive command to the motor 25, it is determined whether or not the rotary encoder 26 has detected the rotation of the motor 25. If the rotary encoder 26 outputs the number of rotations periodically, the card 2 is being conveyed at a constant speed. If the rotary encoder 26 does not output the rotation number regularly (or if there is no output from the rotary encoder 26), the card 2 is jammed. That is, in step S23, it is determined whether or not the card 2 is jammed. If the card 2 is not jammed, the process proceeds to step S24. If the card 2 is jammed, the process proceeds to step S29.

  In step S24, magnetic information is read by the magnetic head 15 from the magnetic stripe of the card 2 being conveyed at a constant speed, and the CPU 20 stores the magnetic information in the RAM 22. The process of step S24 is continuously performed until the driving of the motor 25 is stopped.

  In step S25, the CPU 20 determines whether or not the card detection sensor 6 has detected the card 2. If the card detection sensor 6 detects the card 2, the process returns to step S23. While the card detection sensor 6 continues to detect the card 2, the CPU 20 continues to determine whether the card 2 is jammed. That is, the CPU 20 determines whether or not the card 2 is jammed by repeating the processes of steps S23, S24, and S25. FIG. 22 shows a state where the card detection sensor 6 detects the card 2 and the magnetic head 15 contacts the card 2 and reads magnetic information.

  In step S25 of FIG. 15, when the card detection sensor 6 no longer detects the card 2, the card 2 passes through the insertion slot 3a and is taken into the card processing apparatus 1. In this case, the CPU 20 proceeds to step S26 and stops driving the shutter solenoid 27. Thereby, the shutter 14 is closed. FIG. 23 shows the position of the card 2 when the card detection sensor 6 no longer detects the card 2. Further, the state where the driving of the shutter solenoid 27 is stopped and the shutter 14 is closed is shown.

  When the driving of the shutter solenoid 27 is stopped, in step S27, the CPU 20 determines whether or not the card detection sensor 8 has detected the card 2. The presence of the card 2 at the position of the card detection sensor 8 means that the entire card 2 has passed through the magnetic head 15. FIG. 24 shows a state in which the front end of the card 2 has reached the position of the card detection sensor 8 and the rear end of the card 2 has passed through the magnetic head 15. When the card detection sensor 8 detects the card 2, the CPU 20 stops driving the motor 25 in step S28. Thereby, rotation of each roller 4 stops and conveyance of the card | curd 2 stops. And CPU20 transmits the magnetic information memorize | stored in RAM22 to a high-order apparatus via the communication part 24. FIG. Thereby, the reading process of the magnetic information of the card 2 is completed.

  On the other hand, when the card detection sensor 8 does not detect the card 2 in step S27, the magnetic head 15 and the card 2 are in contact with each other. In other words, the magnetic information reading of the card 2 has not been completed yet. In this case, the CPU 20 returns to step S23, and continues the conveyance of the card 2 by driving the motor 25 and the reading process of the magnetic information of the card 2 by the magnetic head 15.

  Here, it is assumed that a person who intends to perform fraud performs some work on the card processing device 1 so that the card 2 is jammed in the transport path 5. The position of the card 2 when the card 2 is jammed is shown in FIG. In this case, the rotary encoder 26 does not detect the rotation speed of the motor 25 even though the rotation command is output from the CPU 20 to the motor 25. Therefore, the CPU 20 determines in step S23 in FIG. 15 that the rotary encoder 26 does not regularly output the rotation speed of the motor 25. In step S29, the CPU 20 performs card removal prevention processing. Details of the processing in step S29 will be described later. Thereafter, the CPU 20 forcibly ends (abnormally ends) the card processing shown in FIG.

  In the flowchart shown in FIG. 15, as described in step S23, the card removal prevention process is performed when the rotary encoder 26 does not periodically output the rotational speed. In addition to this, the card removal prevention process may be performed only when the rotary encoder 26 does not periodically output the rotation speed and the card detection sensor 6 detects the card 2. In the latter case, the card removal prevention process is performed only when the card 2 exists at the position of the card detection sensor 6.

  FIG. 16 is a flowchart showing the procedure of card removal prevention processing in step S29 of FIG. In step S30, the CPU 20 drives the eccentric cam solenoid 51. Then, as described in FIG. 10, the eccentric cam 60 rotates around the shaft 66, and the outer periphery (tooth portion 65) of the cam portion 62 contacts the card 2. This prevents the card 2 from being taken out from the insertion slot 3a. In step S <b> 31, the CPU 20 notifies the host device of failure information indicating that the card 2 is jammed in the transport path 5 via the communication unit 24.

  FIG. 17 is a flowchart showing details of the magnetic card writing process in step S4 of FIG. When the process of step S3 in FIG. 14 is completed, the card 2 is stopped at the right end of the transport path 5 as shown in FIG. In order to convey the card 2 to the insertion port 3 a side of the conveyance path 5, the CPU 20 starts reverse rotation driving of the motor 25 in step S <b> 40. When the motor 25 is driven in reverse, each roller 4 connected to the motor 25 rotates in a direction (reverse direction) in which the card 2 is conveyed to the insertion port 3a side. As a result, the card 2 is conveyed leftward along the conveyance path 5.

  When the card detection sensor 6 detects the card 2 in step S41, the CPU 20 drives the shutter solenoid 27 in step S42. Thereby, the shutter 14 opens. Therefore, the card 2 is once conveyed to the insertion slot 3a, and magnetic information can be written from the front end of the card 2 in the subsequent processing. The position of the card 2 at this time is the position shown in FIG. Note that the card 2 can be transported from the front end of the card 2 to a position where magnetic information can be written without opening the shutter 14 by lengthening the transport path 5 of the card processing apparatus 1.

  When the insertion detection sensor 17 detects the card 2 in step S43 in FIG. 17, the CPU 20 starts normal rotation driving of the motor 25 in step S44. In step S <b> 45, the CPU 20 receives information to be written on the magnetic card from the host device via the communication unit 24 and stores it in the RAM 22. Subsequently, the CPU 20 writes magnetic information by the magnetic head 15 to the card 2 being transported based on the information stored in the RAM 22. Writing of magnetic information is continuously performed only during a period when the CPU 20 gives a write signal to the magnetic head 15.

  If the card detection sensor 6 no longer detects the card 2 in step S46, the card 2 does not exist at the position of the shutter 14. Therefore, in step S47, the CPU 20 stops driving the shutter solenoid 27. Thereby, the shutter 14 is closed. The position of the card 2 at this time is the position shown in FIG. When the card 2 continues to be conveyed and the card detection sensor 8 detects the card 2 in step S48, the CPU 20 stops driving the motor 25 in step S49. Thereby, rotation of each roller 4 stops and conveyance of the card | curd 2 stops. The position of the card 2 at this time is the position shown in FIG. Thereafter, the CPU 20 ends the magnetic information writing process to the card 2 and proceeds to step S5 in FIG. 14 to perform the card 2 ejection process. Note that the timing at which the CPU 20 receives the information to be written to the card 2 from the host device may be any time before the start of writing by the magnetic head 15 in step S45 of FIG.

  FIG. 18 is a flowchart showing details of the card ejection process in step S5 of FIG. When the process of step S4 in FIG. 14 ends, the card 2 is stopped at the right end of the transport path 5 as shown in FIG. In order to convey the card 2 to the insertion port 3a side of the conveyance path 5 and eject the card 2, the CPU 20 starts reverse rotation driving of the motor 25 in step S60 of FIG. When the motor 25 is driven in reverse, each roller 4 connected to the motor 25 rotates in a direction (reverse direction) in which the card 2 is conveyed to the insertion port 3a side. As a result, the card 2 is conveyed leftward along the conveyance path 5. The reverse drive of the motor 25 is continuously performed until the drive of the motor 25 is stopped in step S65 described later.

  When the card 2 is conveyed to the insertion port 3a side and the card detection sensor 6 detects the card 2 in step S61, the conveyed card 2 is approaching the insertion port 3a. Therefore, in step S62, the CPU 20 drives the shutter solenoid 27. As a result, the shutter 14 is opened, and the card 2 in the transport path 5 can be discharged from the insertion slot 3a.

  In step S <b> 63, the CPU 20 determines whether or not the rotary encoder 26 regularly outputs the rotation speed of the motor 25. Thereby, it is possible to determine whether or not the card 2 is jammed, as in step S23 of FIG.

  If it is determined in step S63 that the rotary encoder 26 does not regularly output the rotation speed of the motor 25, that is, if it is determined that the card 2 is jammed, the CPU 20 removes the card in step S29. The blocking process is executed according to the flowchart of FIG. Thereafter, the CPU 20 forcibly ends (abnormally ends) the card processing.

  On the other hand, when it is determined in step S63 in FIG. 18 that the rotary encoder 26 periodically outputs the rotation speed of the motor 25, that is, when it is determined that the card 2 is not jammed in the transport path 5. In step S64, the CPU 20 determines whether or not a predetermined time has elapsed since the card detection sensor 6 detected the card 2. At this time, the card 2 is conveyed toward the insertion slot 3 a at a constant speed by the rotation of the roller 4. Therefore, the time from when the front end of the card 2 in the ejection direction passes the position of the card detection sensor 6 until the rear end of the card 2 passes through the roller 4 closest to the insertion slot 3 is determined in advance. Therefore, this time is set to the predetermined time described above. If there is no abnormality such as the card 2 being jammed in the card processing device 1, the card 2 has already passed all the rollers 4 after a predetermined time has passed in step S64, so in step S65, the CPU 20 Stops driving the motor 25. Thereby, rotation of each roller 4 stops and conveyance of the card | curd 2 stops. On the other hand, if the predetermined time has not elapsed in step S64, the card 2 has not passed through all the rollers 4, so the CPU 20 continues to convey the card 2 by the rollers 4.

  In the above example, the driving of the motor 25 is stopped by measuring the time, but in addition to this, when the number of card detection sensors in the transport path 5 is increased and the card 2 passes a predetermined position, The driving of the motor 25 may be stopped.

  When the CPU 20 stops driving the motor 25 in step S65, the CPU 20 determines whether or not the insertion detection sensor 17 has detected the card 2 in step S66. When the insertion detection sensor 17 detects the card 2, since the card 2 is present in the insertion slot 3a, it waits for the card 2 to be taken out. When the user removes the card 2 from the insertion slot 3a and the insertion detection sensor 17 no longer detects the card 2, the CPU 20 stops driving the shutter solenoid 27 in step S67. As a result, the shutter 14 is closed and the card ejection process is completed.

  FIG. 19 is a flowchart showing details of the IC card taking process, the IC card reading process, and the IC card writing process in step S7 of FIG. When the process of step S2 in FIG. 14 is completed, as shown in FIG. 20, the leading end of the card 2 (IC card) is inserted into the insertion slot 3a.

  In step S70 of FIG. 19, the CPU 20 determines whether or not the insertion detection sensor 17 has detected insertion of the card 2 into the insertion slot 3a. When the insertion detection sensor 17 detects the insertion of the card 2, the CPU 20 drives the shutter solenoid 27 in step S71. As a result, the shutter 14 is opened, and the card 2 can be inserted into the card processing apparatus 1. In step S72, the CPU 20 starts normal rotation driving of the motor 25. When the motor 25 is driven to rotate forward, the rollers 4 connected to the motor 25 rotate in a direction (forward rotation direction) in which the card 2 is conveyed into the card processing apparatus 1. As a result, the card 2 is conveyed rightward along the conveyance path 5.

  In step S <b> 73, the CPU 20 determines whether the rotary encoder 26 regularly outputs the rotation speed of the motor 25. Thereby, it is possible to determine whether or not the card 2 is jammed, as in step S23 of FIG.

  If it is determined in step S73 that the rotary encoder 26 does not regularly output the rotation speed of the motor 25, that is, if it is determined that the card 2 is jammed, the CPU 20 removes the card in step S29. The blocking process is executed according to the flowchart of FIG. Thereafter, the CPU 20 forcibly ends (abnormally ends) the card processing.

  On the other hand, if it is determined in step S73 that the rotary encoder 26 is outputting the rotational speed of the motor 25 periodically, that is, if it is determined that the card 2 is not jammed in the transport path 5, In S <b> 74, the CPU 20 determines whether or not the card detection sensor 7 has detected the card 2. The position of the card detection sensor 7 is set so that the IC contact of the card 2 reaches the position of the IC contact head 16 when the tip of the card 2 in the card insertion direction reaches the position of the card detection sensor 7. Has been.

  In step S74, when the card detection sensor 7 does not detect the card 2, the CPU 20 returns to step S73 and determines whether or not the card 2 is jammed. If the card detection sensor 7 detects the card 2, the CPU 20 stops driving the shutter solenoid 27 in step S75. Thereby, the shutter 14 is closed. In step S76, the CPU 20 stops driving the motor 25. Thereby, rotation of each roller 4 stops and conveyance of the card | curd 2 stops. At this time, the IC contact of the card 2 is positioned to face the IC contact head 16.

  In step S77, the CPU 20 drives the contact head solenoid 28 to lower the IC contact head 16. As a result, the IC contact head 16 contacts the IC contact of the card 2. In step S <b> 78, the CPU 20 reads information from the IC chip of the card 2 via the IC contact head 16. The CPU 20 stores the read information in the RAM 22. Then, the CPU 20 transmits information stored in the RAM 22 to the host device via the communication unit 24.

  Thereafter, the CPU 20 receives write information from the host device via the communication unit 24. Further, the CPU 20 stores the received information in the RAM 22. In step S79, the CPU 20 writes the write information stored in the RAM 22 into the IC chip of the card 2 via the IC contact head 16. When the writing is completed, the CPU 20 raises the IC contact head 16 by stopping the drive of the contact head solenoid 28 in step S80. As a result, the IC contact head 16 moves away from the IC contact of the card 2. Thereafter, the CPU 20 proceeds to step S5 in FIG. 14 and performs a card 2 ejection process.
