Description

Card processing unit

Technical field

The present invention relates to a kind of card processing unit that reads or write that sticks into capable information that magnetic card or IC-card etc. is recorded information.

Background technology

Card processing unit in the past, through making the roller rotation, the card that will insert from the insertion mouth of card insertion section transmits to device inside.Then, card processing unit reads card with read head and goes up information recorded, perhaps, with write head information is write magnetic card.Then, card processing unit reverses through making roller, will block from inserting a mouthful discharge.

But, on the card processing unit that is installed on the epigyny device as ATM (automatic cash transaction treating apparatus), some persons of hatching a sinister plot are often arranged, card is got lodged in the card processing unit, and card processing unit is done some tricks.At this moment, if the user of ATM will block the insertion mouth that inserts card processing unit, card has just got lodged in the card processing unit.In case take place so unusually, the user is unusual in order to ask to remove, the ATM that is about to leave the place is set, go to teller's place.So just produced problem: at this moment the person of hatching a sinister plot just uses instrument etc. and will get lodged in card in the card processing unit and take out and take away, use should card for malice then.

For addressing the above problem, proposed in the patent documentation of mentioning in the back 1～3 to possess to stop and blocked the card processing unit of quilt from the prevention mechanism of card insertion section taking-up.This stops mechanism, possesses revolvable offset cam, and the driver (actuator) that makes this offset cam rotation.So in case detect the obstruction of card, driver is work just, make the offset cam rotation, and touch through the outer peripheral portion and the clamping that make offset cam, stop from the card insertion section and take out card.

Figure 26 and Figure 27 are the detailed view of the such prevention mechanism of expression.(A) expression of each figure stops the side view of mechanism, and (B) expression stops the planimetric map of mechanism.Also have, in (B), omitted figure (A) card 2, card insertion section 3 and the time gate 14 etc. diagram.

Figure 26 is the state that expression does not drive as the solenoid 13 of driver.Offset cam 10, being configured to axle 11 is the center rotation.Also have, shown in Figure 26 (A), offset cam 10 is with respect to axle 11 off-centre.The periphery 9 towards card 2 one sides of offset cam 10 forms roughly circular-arc.Therefore, unfixing from the axle 11 of offset cam 10 to the distance of periphery 9.On the periphery 9 of offset cam 10, comprise from the distance of axle 11 and are outer peripheral portion 9a of the length L 1 that contact and are the outer peripheral portion 9b of the length L 2 that contacts with card 2 along transfer path 5 transmission with the card 2 that transmits along transfer path 5.Under the state of Figure 26 (A), though outer peripheral portion 9a is facing to transfer path 5, outer peripheral portion 9a does not contact with card 2.On the other hand, as after state, be middle mind-set CW rotation through making offset cam 10 with axle 11, when with outer peripheral portion 9b during in the face of transfer path 5, shown in Figure 27 (A), outer peripheral portion 9b contacts with the surface of blocking 2.

On axle 11, be equipped with and turned round volute spring 12.Turned round volute spring 12, offset cam 10 is applied make it to right handed power.This be because, the lower end of being turned round volute spring 12 hangs on the offset cam 10, on the other hand, the upper end of being turned round volute spring 12 is against on the wall 34.

Shown in Figure 26 (B), on the top of the plunger 54 of solenoid 13, rod 18 is installed, in addition, be provided with volute spring 55 in the periphery of plunger 54.Volute spring 55, the power that rod 18 is applied the direction of leaving solenoid 13.On rod 18, linking the supporting tool 97 that is supported for the attitude of Figure 26 (A) with the top butt of offset cam 10 and offset cam 10.Supporting tool 97 is made up of arm 84, roller 87 and volute spring 88 etc.Arm 84 is the center rotation with axle 86.Axle 86 is fixed on the wall 34 through members such as not shown plate or rods.The periphery of axle 86 is provided with volute spring 88.One end of volute spring 88 is against from the arm on the pawl 90 outstanding on 84, and the other end of volute spring 88 is against through members such as not shown plate or rods and is fixed on the pawl 89 on the wall 34.In the central authorities of arm 84, be provided with pin 83.Pin 83 inserts in the groove 85 that is arranged on the rod 18.In the left side of arm 84, be provided with roller 87.Roller 87 can be the center rotation with axle 92.In addition, roller 87 contacts with the right flank of the piece 91 on the top that is installed in offset cam 10.Therefore, even owing to turned round the elastic force of volute spring 12, offset cam 10 will be middle mind-set CW rotation with axle 11, and the rotation of offset cam 10 also is prevented from.

If solenoid 13 drives, then plunger 54 just is pulled to the inside of solenoid 13.So in Figure 26 (B), after the groove 85 owing to excellent 18 moved up, the end of groove 85 was against on the pin 83, also moves up so sell 83.So, in Figure 26 (B), arm 84 is middle mind-set CW rotation with axle 86.At this moment, roller 87 is the center rotation with axle 92.Therefore, the friction force that between roller 87 and module 91, produces is just little.

When card processing unit 1 detected the obstruction of card 2, solenoid 13 just drove as stated.Figure 27 representes the state that solenoid 13 has driven.In Figure 27 (B), plunger 54 and rod 18 be side shifting upwards.Through moving of groove 85, pin 83 moves up.Because moving of pin 83, arm 84 is middle mind-set CW rotation with axle 86.Because roller 87 is kept out of the way to the back side from the right side of piece 91, offset cam 10 is that the center rotates because of the elastic force of being turned round volute spring 12 with axle 11, and in Figure 27 (B), move to the right on the top of offset cam 10.At this moment, because the elastic force of volute spring 88, arm 84 will counterclockwise rotate for middle mind-set with axle 86., because the elastic force of volute spring 88 makes the back side of piece 91 contact the rotation of blocking extension 84 with roller 87.Shown in Figure 27 (A), because offset cam 10 is middle mind-set CW rotation with axle 11, the outer peripheral portion 9b of offset cam 10 contacts with the surface of card 2.At this moment, the surface action pressing force of 10 pairs of cards 2 of offset cam.

Contact through the surface of offset cam 10, except that above-mentioned pressing force, between the outer peripheral portion 9b of card 2 and offset cam 10, also act on big friction force with card 2.Therefore, transfer to from the insertion mouth 3a of card insertion section 3, can not extract easily even the person of hatching a sinister plot thinks card 2 that tool using etc. will stop up.

In the state of Figure 27 (A), suppose that the person of hatching a sinister plot wants will block 2 from inserting the situation that mouthful 3a extracts with bigger strength.At this moment, because will extract card 2 with bigger strength, and because the friction force between card 2 and the offset cam 10, offset cam 10 will be that the center further rotates to CW with axle 11.So the outer peripheral portion 9b with card 2 contacts will move to roughly identical with the direction that will extract card 2 direction.This state is represented with Figure 28.

In Figure 28 because offset cam 10 axle 11 off-centre relatively, therefore be longer than the outer peripheral portion 9b that in Figure 27 (A), contact with card 2, apart from the distance of axle 11 be L2 ' outer peripheral portion 9b ' with block 2 and contact.Distance L 2 ' is longer than distance L 2.So, bigger pressing force acts on the surface of card 2 from offset cam 10, and offset cam 10 and the friction force of blocking between 2 just become bigger.Therefore, extract card 2 and become more difficult.

Apply under the state of pressing force at 10 pairs of offset cams card 2,, no matter can accomplish that pushing away card from the outside of card processing unit 1 still pulls out card, does not all allow card 2 to move through the lockable mechanism with the position locking of offset cam 10 is set.Figure 29 and Figure 30 are the structural drawing when on stoping mechanism, having set up lockable mechanism.(A) expression side view, (B) expression front view (FV) in each figure.Also have, in figure (A), (B), omitted the diagram that stops supporting tool 97, solenoid 13 and the volute spring 12 etc. of mechanism.In addition, in figure (B), omitted the diagram of wall 34, gate 14 and card insertion section 3 etc.In this example, on the periphery 9 of offset cam 10, form tooth portion 108.

Figure 29 representes the state that solenoid 13 does not drive.On wall 34, platform 130 is installed.Setting tool 134 is installed, and making it is the center rotation with the axle 138 on the platform 130.Setting tool 134 is the position of the stationkeeping of offset cam 10 at Figure 30 (A).In Figure 29 (B),, be provided with pawl 137 in the left side of setting tool 134.At the upside of setting tool 134, be provided with pawl 135.One end of volute spring 131 is installed on the pawl 133 on right side of setting tool 134.The other end of volute spring 131 is hooked in the hole 132 of platform 130.Therefore, on setting tool 134, through the elastic force of volute spring 131, effect has the power that setting tool 134 is counterclockwise rotated for middle mind-set with axle 138.The left side 139 of setting tool 134 is against on the bar 19.Therefore, the state shown in Figure 29 (B) that is rotated in of setting tool 134 stops.In Figure 29 (B), bar 19 is represented with profile line.

If card processing unit detects the obstruction of card 2, just drive solenoid 13 (with reference to Figure 26).Solenoid 13 1 drives, and in Figure 29 (A), offset cam 10 is middle mind-set CW rotation with axle 11 just.And the tooth portion 108 of periphery 9 contacts with card 2.The state of this moment is represented with Figure 30.

In Figure 30, if want to extract card 2, because tooth portion 108 and block the friction force between 2, offset cam 10 more will rotate to CW.So, tooth portion 108 can compress card 2 more, is pulled out to prevent card 2.

Because offset cam 10 is to CW rotation, in Figure 30 (A), the bar of offset cam 10 19 moves to the upper right side.Therefore, shown in Figure 30 (B), bar 19 139 breaks away from from the left side of setting tool 134, so setting tool 134 relies on the elastic force of volute springs 131, counterclockwise rotates for middle mind-set with axle 138.And in the pawl 135 and bar 19 position contacting of upside, the rotation of setting tool 134 stops.So, bar 19 side shifting downwards just.Be that offset cam 10 becomes lockup state.

In this state, when card 2 was inserted from inserting mouthful 3a, because the friction force between card 2 and the tooth portion 108, offset cam 10 will be to rotation counterclockwise.At this moment, in Figure 30 (A), bar 19 will move to the lower left., shown in Figure 30 (B), because the pawl 135 of setting tool 134 contacts with bar 19, offset cam 10 can not be to rotation counterclockwise.Therefore, because offset cam 10 do not rotate, both made when the outside of card processing unit 1 pushes away card 2, card 2 is also mobile.On the other hand, when pulling out card 2, because the friction force between card 2 and the tooth portion 108, offset cam 10 is to the CW rotation, and the surface of 108 pairs of cards 2 of tooth portion compresses more.Therefore, can not extract card 2.

So at tooth portion 108 and card 2 under the state of contact, no matter the outside from card processing unit pushes away card or pulls out card, card 2 is mobile.So, just can prevent that the card 2 that gets lodged in the card processing unit is removed.

When removing the lockup state of offset cam 10, in Figure 30 (B), the pawl of setting tool 134 137 is lifted to upside, it is rotated to CW.And, in Figure 30 (A), press lower beam 19, make offset cam 10 to rotation counterclockwise.So, the arm 84 (with reference to Figure 27) of supporting tool 97, the elastic force of dependence volute spring 88; Counterclockwise rotate for middle mind-set with axle 86; Roller 87 contacts (with reference to Figure 26) with the right flank of the piece 91 of offset cam 10, and the position of offset cam 10 is fixed, and gets back to state shown in Figure 29.

Embodiment:

Below, with reference to accompanying drawing embodiment of the present invention is described.In each figure, use prosign with a part or counterpart.

At first, with reference to Fig. 1 the general structure of the card processing unit of relevant embodiment of the present invention is described.In Fig. 1, insert detecting sensor 17, to block 2 inserted card insertion section 3 this situation of insertion mouth 3a detect.On card 2, record information.When card 2 was magnetic card, the surface of card 2 possessed magnetic stripe, on this magnetic stripe, records information.When card 2 is Contact Type Ic Card, possess the IC contact on the surface of card 2, possess the IC chip that links to each other with the IC contact in the inside of card 2.When card 2 is non-contact IC card, possess the antenna and the IC chip of communication usefulness in the inside of card 2.On Contact Type Ic Card and non-contact IC card, information is recorded on the IC chip.In the explanation of back, be to give an example as IC-card with Contact Type Ic Card.

Insertion detecting sensor 17 1 detects the insertion of card 2, and gate 14 is just opened.Open through gate 14, card 2 can be sent to the inside of card processing unit 1.The transfer path 5 of transfer card 2 is represented with dot-and-dash line.Also have, in Figure 26, gate 14 is disposed at the upside of transfer path 5, but in Fig. 1, gate 14 is disposed at the downside of transfer path 5.

Transfer path 5 constitutes by inserting mouthful 3a and roller up and down 4.Drive roller 4 rotations through motor not shown in Fig. 1 25 (Fig. 2).From inserting the card 2 one and roller 4 butts that mouthful 3a inserts, card 2 just through the roller 4 of rotation, is transmitted by the inside to card processing unit 1. Card detecting sensor 6,7,8 detects having or not of on position separately card 2.After card 2 inserted, if card detecting sensor 6 becomes the state that does not detect card 2 from the state that detects card 2, gate 14 was just closed.

When the card 2 that inserts was magnetic card, in the transport process of magnetic card, magnetic head 15 read the magnetic information of magnetic card, or on magnetic card, writes magnetic information.When the card 2 that inserts is IC-card, card 2 is sent to the position of regulation.Then, drive with solenoid 28 (Fig. 2) through the contact that is used to IC contact 16 is descended, IC contact 16 descends and contacts with the IC contact of IC-card.Then, this IC contact 16 reads information from IC-card, or on IC-card writing information.If read or write end, stop to drive with solenoid 28 (Fig. 2) through contact, IC contact 16 rises, and leaves the IC contact.If read or write end to blocking 2 information, roller 4 is with regard to retrograde rotation, to inserting a mouthful 3a transfer card 2.So the state that never detects card 2 when card detecting sensor 6 becomes the state that detects card 2, gate 14 is just opened.So, card 2 is sent to the outside of inserting mouthful 3a by roller 4.

Near insertion mouthful 3a, be provided with the offset cam 60 that constitutes a part that stops mechanism.Offset cam 60 possesses cam part 62 and bar 63 etc., can be that rotate freely at the center with axle 66.About the detailed structure of the prevention mechanism that comprises this offset cam 60, explanation in the back.

As the unusual example of card that on above-mentioned card processing unit 1, produces, suppose that after the insertion mouth 3a of card insertion section 3 juggled things, when card 2 inserted or discharges, card 2 had got lodged in the situation of the inside of transfer path 5.Although want to rotate roller 4, under the situation that roller 4 does not rotate, card processing unit 1 detects the position that card 2 is jammed in card detecting sensor 6.Card processing unit 1 one detects the obstruction of card 2, after the offset cam stated just drive with solenoid 51 (Fig. 2), in view of the above, offset cam 60 is middle mind-set CW rotation with axle 66 just.So, because the cam part 62 of offset cam 60 contacts with the surface of card 2, produce friction force at offset cam 60 with between blocking 2, therefore outwards extract card 2 and be prevented from from an insertion mouthful 3a.About the detailed action of this situation, explanation in the back.

Next, with reference to Fig. 2 the structure of the electricity of card processing unit 1 is described.In Fig. 2, the each several part of CPU20 control card treating apparatus 1 obtains information from each several part again.When card 2 was magnetic card, magnetic head 15 read magnetic information or writes magnetic information at magnetic stripe in the magnetic stripe of card.When card 2 was IC-card, IC contact 16 contacted with the IC contact of card, reads information or writing information on the IC chip from the IC chip.

As after state, be that rotate at the center through offset cam 60 with axle 66, cam part 62 just can be to the position of leaving card 2 (position of Fig. 8 (D)) and the position that contacts card 2 (position of Figure 10 (D)) displacement.

Get back to Fig. 4, supporting tool 53 is described.Supporting tool 53 shown in Fig. 4 (A), (B), possesses and is configured to criss-cross 4 arm 53a～53d.53a～53d is one-body molded by resin for these arms.Supporting tool 53 is supported by axle 57, and can be that rotate freely at the center with axle 57.Axle 57 is fixed on the not shown framework.

Among 4 arm 53a～53d, the 1st arm 53a links through pin 52 (Fig. 4 (A)) and the plunger 58 (Fig. 4 (C)) of offset cam with solenoid 51.The 2nd arm 53b and the 1st arm 53a extend round about, have the counterweight 56 with the 1st arm 53a balance.Here, counterweight 56 is made up of cylindrical metal, is contained in the cylindrical portion that the 2nd arm 53b end forms.With the 3rd arm 53c of the 1st and the 2nd arm 53a, 53b quadrature, with respect to these two arm 53a, 53b, to extending with the opposite sides of solenoid 51 with offset cam, the otch 64a of formation engages on the holding section 64 of top ends and offset cam 60.The 4th arm 53d that extends round about with the 3rd arm 53c with respect to the 1st and the 2nd arm 53a, 53b, extends to the homonymy of offset cam with solenoid 51, has the function with the counterweight of the 3rd arm 53c balance.

Supporting tool 53, through between itself and offset cam with the volute spring between the solenoid 51 59, be applied among Fig. 4 (A) with axle 57 be the center to anticlockwise acting force.As after state, be that rotate at the center through supporting tool 53 with axle 57, the 3rd arm 53c just can be to the position that engages with offset cam 60 (position of Fig. 8 (A)) and position (position of Figure 10 (the A)) displacement that breaks away from engaging of offset cam 60.

Fig. 6 representes the front cross-sectional view of supporting tool 53.The end of the 1st arm 53a links through pin 52 and the plunger 58 of offset cam with solenoid 51, receives the load of volute spring 59 again, so corresponding load just is applied on the 1st arm 53a.So,, be provided with counterweight 56 in the end of the 2nd arm 53b for obtaining the balance with the 1st arm 53a.In addition, symbol 81 is flange parts of axle 57, and symbol 82 is the E type circles that are contained in axle 57 ends.

Below, with reference to Fig. 7 the balance of supporting tool 53 is described.Because Fig. 7 is the key diagram of equilibrium principle, therefore with supporting tool 53 patterns illustrate.Fig. 7 (A) is a planimetric map, and Fig. 7 (B) is a front view (FV).

In Fig. 7 (A), with X coordinate and the direction of Y setting coordinate for scheming, the plane that will comprise 4 arm 53a～53d is called the XY plane.This XY plane is equivalent to the 1st plane among the present invention.At this moment, on the XY plane, with supporting tool 53 will be when arrow a direction be rotated rotation center as the axle center of axle 57.This rotation center just is equivalent to the 1st rotation center among the present invention.

Here, as above-mentioned,, on the 2nd arm 53b, be provided with counterweight 56 with the 1st arm 53a balance for the 1st arm 53a and the 2nd arm 53b.In addition, for the 3rd arm 53c and the 4th arm 53d, the 4th arm 53d has the function with the counterweight of the 3rd arm 53c balance.Thereby, on the XY plane, the centre of gravity place of supporting tool 53, consistent with rotation center (axle center of axle 57).

On the other hand, in Fig. 7 (B),, will comprise axle 57 and be called the XZ plane with the plane of XY plane with the direction of Z setting coordinate for figure.This XZ plane just is equivalent to the 2nd plane among the present invention.At this moment, on the XZ plane, supporting tool 53 will the rotation center when arrow b direction is rotated be exactly the some P on the axle center of axle 57.

, design the shape and the weight of each arm 53a～53d, counterweight 56, flange part 81 and E type circle 82 etc. here, so that make the centre of gravity place of the supporting tool 53 on the XZ plane, (some P) is consistent with conplane rotation center.

Like this, in this embodiment, on the XY plane, the centre of gravity place of supporting tool 53 is consistent with rotation center, and on the XZ plane, the centre of gravity place of supporting tool 53 is also consistent with rotation center.Therefore, no matter in all around, apply vibration on which direction up and down or impact, can not produce torques to supporting tool 53.

Return Fig. 4, describe in the face of lockable mechanism 200 down.Shown in Fig. 4 (B), lockable mechanism 200 possesses: setting tool 70, support axle 78 that this setting tool 70 rotates freely, setting tool 70 applied the framework 80 of being turned round volute spring 79 and stationary shaft 78 of elastic force.

Setting tool 70 has: form arciform part 1 71, the part 2 72 of extending to the directions parallel with axle 78 from this part 1 71 and the 3rd part 73 of extending to vertical direction from this part 2 72.On part 1 71, be provided with: the fastener 75 of the operating sheet 74 that locking is used to when removing setting tool 70 is rotated, the bar 63 that card ends offset cam 60 and can with the claw 77 of bar 63 butts.In addition, on the 3rd part 73, being provided with can be by the claw 76 of projection 67 promotions of bar 63.The 1st claw, claw 77 that claw 76 is equivalent among the present invention are equivalent to the 2nd claw among the present invention.

Part 1 71 and the 3rd part 73, the axle 78 that is fixed on the framework 80 runs through.So, setting tool 70 can be the center with axle 78 just, to rotating near the direction (counterclockwise) of the bar 63 of offset cam 60 with as the direction of leaving bar 63 (CW) of removing direction as the locking direction.On the fastener 75 of part 1 71, formative gear shape concavo-convex.Turned round volute spring 79, one ends and be supported on the framework 80, the other end links with the pin 81 (Fig. 4 (A)) that is fixed on the part 1 71.In Fig. 4 (C), setting tool 70 is turned round volute spring 79 through this and is applied in axle 78 and is the anticlockwise acting force of middle mind-set.

Below, with reference to Fig. 8～Figure 13, the action that stops mechanism 100 and lockable mechanism 200 is described.

(during standby) under normal conditions stops mechanism 100 to be in state shown in Figure 8.In Fig. 8, (A) be planimetric map, (B) be oblique view, (C) be front view (FV), (D) be side view.In addition, in Fig. 8, omitted the diagram of lockable mechanism 200.

Under the state of Fig. 8, offset cam does not move with solenoid 51, and the otch 64a that forms on the top of the 3rd arm 53c of supporting tool 53 and the holding section 64 of offset cam 60 engages.And supporting tool 53 receives the elastic force of volute spring 59, be applied in the axle 57 among Fig. 8 (A) to be the anticlockwise acting force of middle mind-set, thereby above-mentioned fastening state is maintained.

On the other hand; Offset cam 60, though through turned round volute spring 69 (Fig. 8 (B)) receive with axle 66 be the center to clockwise power, as above-mentioned; Because the top of the 3rd arm 53c engages with the holding section 64 of offset cam 60, can not rotate to CW.Therefore, offset cam 60 is in the position shown in Fig. 8 (D), this position be cam part 62 leave card 2 and not to block 2 apply pressing force the position, be equivalent to the 1st position among the present invention.

Fig. 9 representes when stoping mechanism 100 to be in the state of Fig. 8, the state of lockable mechanism 200.In Fig. 9, (A) be planimetric map, (B) be oblique view, (C) be front view (FV), (D) be side view.Also have, in Fig. 9, omitted the diagram of offset cam with solenoid 51 and supporting tool 53.

Under the state of Fig. 9, setting tool 70 has been applied in axle 78 and has been the anticlockwise acting force of middle mind-set through turning round volute spring 79, and part 1 71 is against the side of the bar 63 of offset cam 60.Thereby setting tool 70 can not continue to counterclockwise rotating.

According to after the method stated, if detect the obstruction of card 2, stop mechanism 100 just to become state shown in Figure 10.In Figure 10, (A) be planimetric map, (B) be oblique view, (C) be front view (FV), (D) be side view.Also have, in Figure 10, omitted the diagram of lockable mechanism 200.

Under the state of Figure 10, offset cam is with solenoid 51 work, and the 1st arm 53a of supporting tool 53 is drawn by the plunger 58 of offset cam with solenoid 51 through pin 52.Thereby supporting tool 53 overcomes the elastic force of volute spring 59, in Figure 10 (A), is that middle mind-set CW rotates with axle 57.Therefore, the top of the 3rd arm 53c, the 64 otch 64a disengagings that form from the holding section of offset cam 60, the 3rd arm 53c is disengaged with engaging of offset cam 60.

Consequently, offset cam 60 owing to turned round the elastic force of volute spring 69, is that middle mind-set CW rotates with axle 66, to the position displacement shown in Figure 10 (D).To be cam part 62 with card 2 contact in this position and to block 2 apply pressing force the position, be equivalent to the 2nd position among the present invention.

In this state, the same with the situation of Figure 27, want that more will block 2 from an insertion mouthful 3a extracts, the pressing force of 62 pairs of cards 2 of cam part is strong more, extracts card 2 and just becomes more difficult.Particularly, the surface that card 2 is bitten by the tooth portion 65 that forms on the cam part 62, thus, from insert a mouthful 3a will block 2 extract with regard to more difficult.

Figure 11 is illustrated in when stoping mechanism 100 to be in the state of Figure 10, the state of lockable mechanism 200.In Figure 11, (A) be planimetric map, (B) be oblique view, (C) be front view (FV), (D) be side view.Also have, in Figure 11, omitted the diagram of offset cam with solenoid 51 and supporting tool 53.

Along with offset cam 60 to the position displacement shown in Figure 10 (D), bar 63 pops up.Therefore, the setting tool 70 of lockable mechanism 200 owing to turned round the acting force of volute spring 79, further rotates to counter clockwise direction (locking direction) from the position of Fig. 9 (C), and shown in Figure 11 (C), stops in the position with bar 63 butts.At this moment, also through being fixed in the pin 81 on the setting tool 70, the butt with the end of the guiding groove 80a of formation on framework 80 limits the rotation of setting tool 70.

In this state, the part of the fastener 75 of setting tool 70 is ended with bar 63 cards.Thereby, just can not remove the cam part 62 of offset cam 60 and contacting of card 2 by lower beam 63.Offset cam 60 in the position shown in Figure 10 (D) by locking.Like this, can prevent more reliably that will block 2 from an insertion mouthful 3a extracts.In addition, under the state of Figure 11, between fastener 75 and bar 63, also can be gapped slightly.Said among the present invention " card ends " also comprises this situation.

When removing the locking of offset cam 60, the operation below carrying out.Figure 12 and Figure 13 are the key diagrams of this situation.In each figure, (A) be planimetric map, (B) be oblique view, (C) be front view (FV), (D) be side view.Also have, each figure has omitted the diagram of offset cam with solenoid 51 and supporting tool 53.

At first, shown in figure 12, control the operating sheet 74 of setting tool 70, setting tool 70 is rotated for middle mind-set CW (releasing direction) with axle 78.This rotation; Though will overcome the elastic force of being turned round volute spring 79 on the way; But making setting tool 70 turn to the time point of a certain degree, turned round volute spring 79 and carry out snap fastener (snap) action, its resilient force makes setting tool 70 rotate to CW.Therefore, after making setting tool 70 turn to the position shown in Figure 12 (C), even remove the controlling of operating sheet 74, setting tool 70 also can not rotate to counterclockwise (locking direction), and static in this position.Also have, on the position of Figure 12 (C), because the end butt of the guiding groove 80a of the pin 81 of setting tool 70 and framework 80, being rotated further of setting tool 70 is limited.

Next, shown in figure 13, press the bar 63 of offset cam 60.At this moment,, and not hindered by setting tool 70, therefore can bar 63 be pressed because the fastener 75 of setting tool 70 moves back to the side of bar 63.Along with pressing of bar 63, offset cam 60 counterclockwise rotates for middle mind-set with axle 66.Therefore, shown in Figure 13 (D), cam part 62 is left from blocking 2.

If further press lower beam 63 from the state of Figure 13, because the claw 76 that on the 3rd part 73 of setting tool 70, forms is promoted by the projection that is provided with on the bar 63 67, be the center just setting tool 70 begins with axle 78, rotate to counter clockwise direction (locking direction).So if bar 63 is pressed to the end, setting tool 70 resets to the position of Fig. 9.

Like this, through on bar 63, being provided with projection 67, and promote the structure of claws 76 with this projection 67, the amount of pressing of the bar 63 when setting tool 70 is kept in the center is very little just passable, the operability raising.

On the other hand; Along with pressing of bar 63, if offset cam 60 is to counterclockwise rotating, then the top of the 3rd arm 53c of supporting tool 53 just receives the elastic force of volute spring 59; And engage with the otch 64a of the holding section 64 of offset cam 60, supporting tool 53 resets to the position of Fig. 8.

Through above-mentioned operation, the locking of offset cam 60 is disengaged, and stops mechanism 100 to get back to the state of Fig. 8, and lockable mechanism 200 is got back to the state of Fig. 9.

According to above-mentioned embodiment, offset cam can link with the 3rd arm 53c that engages with the offset cam 60 any arm in addition in the middle of 4 arm 53a～53d with solenoid 51.In this embodiment, offset cam is to link with the 1st arm 53a with solenoid 51, but also can offset cam be linked with the 2nd arm 53b or the 4th arm 53d with solenoid 51.For example, when offset cam is linked with solenoid 51 and the 2nd arm 53b, just on the 1st arm 53a, counterweight 56 is set.

Because the arm beyond the 3rd arm 53c; It is the arm that does not have application point (part that engages with offset cam 60); Therefore; If offset cam is linked with solenoid 51 and these arms, this solenoid 51 just becomes the some position in addition on the line of fulcrum that is positioned at armite (axle 57) and application point is drawn.Therefore, compare, the configuration offset cam is able to mitigation with the position of solenoid 51 and the restriction of direction, can improve the degree of freedom of configuration with the situation that point on the line of such fulcrum and application point to armite in the past draws.

In addition; In this embodiment,, vibrate or impact owing to apply in any direction as with the explanation that Fig. 7 was done; Can not produce torque to supporting tool 53; So even offset cam 60 does not apply big load to supporting tool 57, do not worry owing to vibratory impulse yet, and make the engaging of offset cam 60 and supporting tool 57 break away from 100 maloperations of back prevention mechanism.Thereby owing to need not increase the elastic force of being turned round volute spring 69 (Fig. 8 (B)), the acting force that therefore offset cam 60 is applied is very little just passable.Consequently, the power of bar 63 of pressing offset cam 60 is very little just passable, and the operation that the locking of offset cam 60 is removed becomes easy.

Also have; In this embodiment; Because the load of the snap portions (application point) of supporting tool 57 and offset cam 60 is little; Therefore need not be as in the past, on supporting tool 57, be provided for the roller 87 (Figure 26) that reduces to rub, only let on the holding section 64 of top and offset cam 60 of the 3rd arm 53c the otch 64a of formation engage and get final product.Like this, just can omit roller and reduce cost.

In addition, in this embodiment, some improvement on lockable mechanism 200, have also been used.In lockable mechanism in the past, when offset cam during not by locking, if, rotate and the problem of maloperation (becoming lockup state) with regard to there being offset cam by error to removing direction operation setting tool.If specifically describe, be exactly in Figure 29 (non-lockup state), if the pawl 137 of setting tool 134 is firmly upwards pushed away, then pawl 137 and bar 19 butts, it is the clockwise power at center that offset cam 10 receives with axle 11.If this power is big, the fastening state of offset cam 10 and arm 84, from the state of Figure 26 state-transition to Figure 27, offset cam 10 rotates to CW, and becomes lockup state.

And in the lockable mechanism 200 of this embodiment, offset cam 60 not by the state of Fig. 9 of locking under, by error with setting tool 70 when removing direction (CW) operation, the claw 77 and bar 63 butts of setting tool 70.At this moment, because claw 77 is shapes of tip, the conical surface of claw 77 is line with the following edge of bar 63 and contacts.And if continue to removing direction operation setting tool 70, though 77 pairs of bars 63 of claw have applied stronger power, this power has played the effect of the engaging power that strengthens offset cam 60 and supporting tool 53.

That is, the result at the edge below the conical surface catch bar 63 of claw 77 is that bar 63 also receives the power left of claw 77 in Fig. 9 (C) except the power that makes progress.Since this power left, in Fig. 8 (A), bar 63 displacement to the left.Thereupon, because holding section 64 also to the left, that is to say the reverse direction displacement to the direction that breaks away from engaging of the 3rd arm 53c, so the 3rd arm 53c becomes firmer with engaging of holding section 64.Consequently, even to removing direction operation setting tool 70, offset cam 60 can not become lockup state (Figure 10) because of maloperation yet.

Below, carry out reading and writing of information from the card 2 of 1 pair of insertion of card processing unit, describe to blocking 2 processing of discharging.Also have, also to when blocking 2 insertion or discharging, the processing when card 2 stops up describes.

Figure 14 is the process flow diagram that is illustrated in the summary that card is handled on the card processing unit 1.In step S1, CPU20 is through the kind of Department of Communication Force 24 from epigyny device receiving card 2.Here, suppose magnetic card and Contact Type Ic Card kind as card 2.Next, in step S2, whether CPU20 is that magnetic card is judged to the kind of the card 2 that receives.When being judged to be magnetic card, in step S3, the processing that CPU20 carries out that takeing in of magnetic card handled and reads magnetic information from magnetic card.Then, in step S4, CPU20 carries out writing to magnetic card the processing of magnetic information.Then, in step S5, CPU20 blocks 2 discharge processing.About the card of step S3, S4, S5 handle in detail, after state.

On the other hand, in step S2, when the kind of the card 2 that receives when judgement was not magnetic card, in step S6, whether CPU20 was that IC-card is judged to the kind of the card 2 that receives.When being judged to be IC-card, in step S7, CPU20 carries out takeing in processing, reading information and to the processing of IC-card writing information from IC-card of IC-card.Then, in step S5, CPU20 blocks 2 discharge processing.About the card of step S7 handle in detail, after state.

In addition, in step S6, when the kind of the card 2 that receives when judgement was not IC-card, each item that CPU20 does not carry out step S7 was handled and is entered step S5, blocked 2 discharge and handled.This is because the IC-card that the card that is inserted into promptly is not the magnetic card of supposition neither be supposed, thereby can not block processing.

Figure 15 is illustrated in that takeing in of magnetic card among the step S3 of Figure 14 handled and the detailed process flow diagram that reads processing of magnetic card.In step S20, whether CPU20 detects card 2 (magnetic card) to insertion detecting sensor 17 is judged to the insertion of inserting mouthful 3a.Figure 20 representes that card 2 has been inserted into the state that inserts mouthful 3a.In this state, because card 2 the front end no show position of inserting detecting sensor 17 also, so gate 14 is being closed.

If insert the insertion that detecting sensor 17 detects card 2, then CPU enters following step S21.In step S21, CPU20 drives gate with solenoid 27.So, shown in figure 21, gate 14 is opened transfer path 5.Figure 21 representes that card 2 has been inserted into the state of card processing unit 1 inside.Then, in the step S22 of Figure 15, the just commentaries on classics that CPU20 begins motor 25 drives.Just commentaries on classics through motor 25 drives, each roller 4 that links to each other with motor 25, the direction that transmits towards the inside that will block 2 past card processing units 1 (positive veer) rotation.So, be inserted into and begin from inserting mouthful nearest roller 4 butt time points of 3a from its front end, card 2 is just through each roller 4, transmitted over to the right with certain speed along transfer path 5.In the transport process of card 2, the magnetic information of record reads on 15 pairs of cards 2 of magnetic head.

CPU20 based on the rotating speed of the motor 25 that obtains from the output of rotary encoder 26, through carrying out FEEDBACK CONTROL, keeps fixing with the rotating speed of motor 25.In the step S28 of Figure 15, stop before the driving of motor 25, CPU20 controls, so that make motor 25 just change driving continuously with certain speed.

In step S23, whether CPU20 exports the rotating speed of motor 25 termly rotary encoder 26 and judges.For example, CPU20 with to motor 25 transmission driving command accordingly, judges the rotation whether rotary compiler 26 detects motor 25.If rotary encoder 26 is output speed termly, card 2 just is transmitted with certain speed.If rotary encoder 26 is output speed (if perhaps not having the output of rotary encoder 26) termly not, then block 2 and just stop up.That is,, whether stop up and judge blocking 2 at step S23.Do not stop up if block 2, then enter step S24, stopped up, then enter step S29 if block 2.

At step S24, CPU20 is through magnetic head 15, in the magnetic stripe of the card 2 that transmits with certain speed, reads magnetic information, and makes this information stores to RAM22.Driving up to motor 25 stops, and the processing of step S24 is carried out continuously.

In step S25, whether CPU20 detects card 2 to card detecting sensor 6 is judged.When card detecting sensor 6 detects card 2, return the processing of step S23.At card during detecting sensor 6 continues to detect card 2, whether CPU20 is lasting stops up and judges blocking 2.That is whether, CPU20 is through the processing of repeating step S23, S24, S25, stop up and judge blocking 2.Figure 22 representes that card detecting sensor 6 detects card 2, also have, magnetic head 15 with block 2 and contact and reading the state of magnetic information.

In the step S25 of Figure 15, when card detecting sensor 6 can't check card 2, card 2 was in through inserting a mouthful 3a, is taken in the state of the inside of card processing unit 1.At this moment, enter step S26, CPU20 stops the driving of gate with solenoid 27.So, gate 14 is closed.The position of the card 2 when Figure 23 representes that card detecting sensor 6 can't check card 2 also has, and gate stops with the driving of solenoid 27, and gate 14 closing state.

If gate stops with the driving of solenoid 27, in step S27, whether CPU20 just detects card 2 to card detecting sensor 8 is judged.The existence of card 2 is arranged in the position of card detecting sensor 8, mean that card 2 integral body are through magnetic head 15.Figure 24 representes the position of front end detecting sensor 8 to the Dacca of card 2, and the state of magnetic head 15 has been passed through in the rear end of card 2.If card detecting sensor 8 detects card 2, then in step S28, CPU20 stops the driving of motor 25.So, the rotation of each roller 4 stops, and the transmission of card 2 stops.Then, CPU20 sends the magnetic information that is stored on the RAM22 through Department of Communication Force 24 to epigyny device.Like this, the processing of reading of the magnetic information of card 2 finishes.

On the other hand, in step S27, when card detecting sensor 8 does not detect card 2, be to be in magnetic head 15 and card 2 state of contact.In other words, be that the magnetic information of card 2 does not read the state that finishes as yet.At this moment, CPU20 returns step S23, the transmission of the card of proceeding to carry out 2 through the driving of motor 25, and the magnetic information of the card of carrying out through magnetic head 15 2 read processing.

, suppose the person of hatching a sinister plot here, want on card processing unit 1, to juggle things, get lodged on the transfer path 5 so that block 2.The position of the card 2 when expression card 2 stops up in Figure 25.At this moment, though CPU20 exports rotate instructions to motor 25, rotary encoder 26 does not but detect the rotating speed of motor 25.Therefore, CPU20 is judged to be the rotating speed that rotary encoder 26 is not regularly exported motor 25 in the step S23 of Figure 15.So in step S29, CPU20 carries out card taking and stops processing.About the processed content of step S29, after state.Then, CPU20 is shown in figure 14, forces to finish (abnormal ending) card and handles.

In process flow diagram shown in Figure 15, the explanation of being done like step S23 when rotary encoder 26 not termly during output speed, will be carried out card taking and stop and handle.In addition, also can be, only rotary encoder 26 termly output rotation speed and card detecting sensor 6 detect under the situation of card 2, just carry out card taking prevention processing.The latter's situation is just carried out card taking and is stoped processing when card 2 is present in the position of card detecting sensor 6.

Figure 16 is illustrated in the process flow diagram that card taking among the step S29 of Figure 15 stops processed steps.In step S30, CPU20 drives offset cam with solenoid 51.So like the explanation that Figure 10 did, offset cam 60 is that rotate at the center with axle 66, the periphery of cam part 62 (tooth portion 65) contacts with card 2.So, be prevented from from inserting a mouthful 3a taking-up card 2.And in step S31, CPU20 is through Department of Communication Force 24, and just expression card 2 has got lodged in the failure message of the meaning on the transfer path 5, gets in touch with epigyny device.

Figure 17 is illustrated in the detailed process flow diagram that magnetic card among the step S4 of Figure 14 writes processing.In the moment that the processing of the step S3 of Figure 14 finishes, shown in figure 24, card 2 stops at the right-hand member of transfer path 5.For will block 2 be sent to transfer path 5 insertion mouth 3a, in step S40, the reverse that CPU20 begins motor 25 drives.Reverse through motor 25 drives, and each roller 4 that links to each other with motor 25 is to blocking 2 toward inserting mouthful direction (reverse direction) that 3a one side a transmits rotation.So, card 2 is transmitted left in the past along transfer path 5.

In step S41, if card detecting sensor 6 detects card 2, then in step S42, CPU20 drives gate with solenoid 27.So, gate 14 is opened.Thereby card 2 is sent to for the time being inserts a mouthful 3a, in the middle of the processing of back, can begin to write magnetic information from blocking 2 front end.At this moment blocking 2 position is position shown in figure 22.In addition, the transfer path 5 through lengthening card processing unit 1 need not open the sluices 14, just can be sent to and can begin to write the position of magnetic information from blocking 2 front end blocking 2.

In the step S43 of Figure 17, detect card 2 if insert detecting sensor 17, in step S44, the just commentaries on classics that CPU20 begins motor 25 drives.Then, in step S45, CPU20 writes the information of magnetic card from the epigyny device reception, and is stored in RAM22 through Department of Communication Force 24.Next, CPU20 is based on the information that is stored in the RAM22, and the card 2 in transmitting writes magnetic information through magnetic head 15.Writing of magnetic information, carried out during magnetic head 15 sends write signal at CPU20 continuously.

In step S46, when card detecting sensor 6 can't check card 2, card 2 did not exist in the position of gate 14.Thereby in step S47, CPU20 stops the driving of gate with solenoid 27.Like this, gate 14 is closed.At this moment blocking 2 position, is position shown in Figure 23.So card 2 is continued to transmit, in step S48, if card detecting sensor 8 detects card 2, then in step S49, CPU20 just stops the driving of motor 25.Like this, the rotation of each roller 4 stops, and the transmission of card 2 stops.Block 2 position this moment, is position shown in Figure 24.Then, CPU20 finishes the processing that writes to the magnetic information of card 2, enters the step S5 of Figure 14, blocks 2 discharge processing.Also have, receive period of the information that writes card 2 from epigyny device,, when can so long as in the step S45 of Figure 17, write before the beginning through what magnetic head 15 carried out about above-mentioned CPU20.

Figure 18 is illustrated among the step S5 of Figure 14 card to discharge the detailed process flow diagram of handling.The processing finish time in the step S4 of Figure 14, shown in figure 24, card 2 is parked in the right-hand member of transfer path 5.Transmit to the insertion mouth 3a of transfer path 5 side in order to block 2, and will block 2 and discharge, in the step 60 of Figure 18, CPU20 begins the reverse driving of motor 25.Reverse through motor 25 drives, and each roller 4 that links to each other with motor 25 is to blocking 2 toward inserting mouthful direction (reverse direction) that 3a one side a transmits rotation.Like this, card 2 is transmitted in the past left along transfer path 5.After before the driving of motor 25 stops among the step S65 that stating, the reverse of motor 25 drives to be carried out continuously.

Insert mouthful 3a one side when card 2 is sent to, in step S61, when card detecting sensor 6 detected card 2, the card 2 that is transmitted was near inserting a mouthful 3a.So in step S62, CPU20 drives gate with solenoid 27.So, gate 14 is opened, and just can the card on the transfer path 52 be discharged from inserting mouthful 3a.

In step S63, CPU20 judges the rotating speed whether rotary encoder 26 exports motor 25 termly.Like this, identical with the step S23 of Figure 15, can whether stop up and judge blocking 2.

In step S63, when judging that rotary encoder 26 is not exported the rotating speed of motor 25 termly, when promptly being judged to be card 2 obstructions, CPU20 is by the flow process of above-mentioned Figure 16, and the card taking of execution in step S29 stops to be handled.Then, CPU20 forces to finish the processing of (abnormal ending) card.

On the other hand; In the step S63 of Figure 18, when judging that rotary encoder 26 is exported the rotating speed of motor 25 termly, promptly be judged to be card 2 when on transfer path 5, not stopping up; In step S64, whether CPU20 has passed through the stipulated time and has judged detecting card 2 from card detecting sensor 6.At this moment, card 2 is transmitted to inserting mouthful 3a with certain speed through the rotation of roller 4.Thereby,, through the time till inserting the nearest roller 4 of mouthful 3a, be predetermined to the rear end of card 2 from the front end that blocks 2 discharge direction position through card detecting sensor 6.Therefore, it is this time set the above-mentioned stipulated time.When to take place that on card processing unit 1 card 2 stops up etc. unusual, at step S64, if the stipulated time process, because card 2 has finished through all rollers 4, therefore in step S65, CPU20 stopped the driving of motor 25.Like this, the rotation of each roller 4 stops, and the transmission of card 2 stops.On the other hand, at step S64,, also finish owing to block 2, so CPU20 proceeds the transmission through the card 2 of roller 4 execution through all rollers 4 if do not pass through the stipulated time.

In the middle of above-mentioned example, be the driving that stops motor 25 through the instrumentation time, but in addition, also can on transfer path 5, increase the quantity of card detecting sensor, when card 2 passes through appointed positions, stop the driving of motor 25.

In step S65, if CPU20 stops the driving of motor 25, in step S66, whether CPU20 just detects card 2 to insertion detecting sensor 17 is judged.When insertion detecting sensor 17 detects card 2, owing to, wait for that then card 2 is removed inserting mouthful 3a place card 2 existence.When the user can't check card 2 from inserting a mouthful 3a taking-up card 2, inserting detecting sensor 17, in step S67, CPU20 stopped the driving of gate with solenoid 27, and like this, gate 14 is closed, and card is discharged the processing end.

Figure 19 is illustrated in IC-card among the step S7 of Figure 14 to take in processing, IC-card and read and handle and IC-card writes the detailed process flow diagram of processing.Shown in figure 20, in the moment that the processing of the step S2 of Figure 14 finishes, the front end that is in card 2 (IC-card) is inserted into the state that inserts mouth 3a.

In the step S70 of Figure 19, whether CPU20 detects card 2 to insertion detecting sensor 17 is judged to the insertion of inserting mouthful 3a.If insert the insertion that detecting sensor 17 detects card 2, in step S71, CPU20 drives gate with solenoid 27.So, gate 14 is opened, and just can card 2 be inserted into the inside of card processing unit 1.Then, in step S72, the just commentaries on classics that CPU20 begins motor 25 drives.Just commentaries on classics through motor 25 drives, and each roller 4 that links to each other with motor 25 is to blocking 2 toward the card processing unit 1 inner direction that transmits (positive veer) rotation.Like this, card 2 is transmitted to the right in the past along transfer path 5.

In step S73, CPU20 judges the rotating speed whether rotary encoder 26 exports motor 25 termly.So, the same with the step S23 of Figure 15, can whether stop up and judge blocking 2.

In step S73, when judging that rotary encoder 26 is not exported the rotating speed of motor 25 termly, when promptly being judged to be card 2 obstructions, CPU20 is by the flow process of above-mentioned Figure 16, and the card taking of execution in step S29 stops to be handled.Then, CPU20 forces end-card to handle (abnormal ending).

On the other hand, in step S73, export rotation when speed of motor 25 termly when being judged to be rotary encoder 26, promptly judge card 2 when transfer path does not stop up, in step S74, whether CPU20 detects card 2 to card detecting sensor 7 is judged.Set the position of card detecting sensor 7 so that at the front end of the card 2 of card insertion direction in the position of Dacca detecting sensor 7, the IC contact of card 2 arrives the position of IC contact 16.

Whether in step S74, when card detecting sensor 7 when not detecting card 2, CPU20 returns step S73, stop up and judge blocking 2.When card detecting sensor 7 detected card 2, in step S75, CPU20 stopped the driving of gate with solenoid 27.Like this, gate 14 is closed.Then, at step S76, CPU20 stops the driving of motor 25, and so, the rotation of each roller 4 stops, and the transmission of card 2 stops.At this moment, card 2 IC-card contact with IC contact 16 opposed position.

In step S77, CPU20 drives contact with solenoid 28, and IC contact 16 is descended.So, IC contact 16 contacts with the IC contact of card 2.Then, in step S78, CPU20 is through IC contact 16, reads information from blocking 2 IC chip.CPU20 arrives RAM22 to the information stores that reads.Then, CPU20 sends the information that is stored among the RAM22 through Department of Communication Force 24 to epigyny device.

Then, CPU20 receives writing information through Department of Communication Force 24 from epigyny device.In addition, CPU20 arrives RAM22 to this information stores that receives.Then, in step S79, CPU20 writes through IC contact 16 in the IC chip of card 2 being stored in the writing information among the RAM22.If write end, in step S80, CPU20 rises IC contact 16 through stopping the driving of contact with solenoid 28.So, IC contact 16 leaves from blocking 2 IC contact.Then, CPU20 enters the step S5 of Figure 14, blocks 2 discharge processing.
