Description

Card processing unit

Technical field

The present invention relates to and a kind of the reading of information or the card processing unit of write are carried out to the card that magnetic card or IC-card etc. record information.

Background technology

Card processing unit in the past, by making roller rotate, the card insert port from card insertion section inserted transmits to device inside.Then, card processing unit read head reads the information of the upper record of card, or, with write head, information is write magnetic card.Then, card processing unit reverses by making roller, will block and discharge from insert port.

But, on the card processing unit being installed on the epigyny device as ATM (automatic cash transaction treating apparatus), often have some persons of hatching a sinister plot, make blocking consciously in card processing unit, and some tricks are done to card processing unit.At this moment, if card is inserted the insert port of card processing unit by the user of ATM, card has just got lodged in card processing unit.Once there is such exception, user removes extremely to ask, and the setting place of the ATM that is about to leave, goes to the place of teller.So, just create problem: at this moment the card got lodged in card processing unit taking-up just can take away with instrument etc. by the person of hatching a sinister plot, and then malice uses this card.

For solving the problem, in the patent documentation 1 ~ 3 mentioned later, propose the card processing unit possessing and stop and block by the prevention mechanism taken out from card insertion section.This prevention mechanism, possesses revolvable offset cam, and the driver (actuator) that this offset cam is rotated.So once detect the blocking of card, driver is work just, makes offset cam rotate, and by making the outer peripheral portion of offset cam contact with card, stoping and taking out card from card insertion section.

Figure 26 and Figure 27 is the detailed view representing such prevention mechanism.(A) of each figure represents the side view stoping mechanism, and (B) represents the planimetric map stoping mechanism.Further, eliminate in (B) card 2 of figure (A), card insertion section 3 and time gate 14 etc. diagram.

Figure 26 is the state representing that the solenoid 13 as driver does not drive.Offset cam 10, is configured to rotate centered by axle 11.Further, as shown in Figure 26 (A), offset cam 10, eccentric relative to axle 11.The periphery 9 towards card 2 side of offset cam 10, forms roughly arc-shaped.Therefore, do not fix from the axle 11 of offset cam 10 to the distance of periphery 9.On the periphery 9 of offset cam 10, the distance comprised from axle 11 is the outer peripheral portion 9a of the length L1 do not contacted with the card 2 transmitted along transfer path 5 and is the outer peripheral portion 9b of the length L2 contacted with the card 2 transmitted along transfer path 5.Under the state of Figure 26 (A), although 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 aftermentioned, by making offset cam 10 rotate clockwise centered by axle 11, when by outer peripheral portion 9b in the face of transfer path 5 time, as shown in Figure 27 (A), outer peripheral portion 9b with card 2 surface contact.

On axle 11, torsion coil spring 12 is installed.Torsion coil spring 12, applies the power making it rotate clockwise to offset cam 10.This is because the lower end of torsion coil spring 12 hangs on offset cam 10, on the other hand, the upper end of torsion coil spring 12 is against on wall 34.

As shown in Figure 26 (B), on the top of the plunger 54 of solenoid 13, rod 18 is installed, in addition, the periphery of plunger 54 is provided with volute spring 55.Volute spring 55, applies to rod 18 power leaving the direction of solenoid 13.On rod 18, link the supporting tool 97 abutting the attitude also offset cam 10 being supported for Figure 26 (A) with the top of offset cam 10.Supporting tool 97 is made up of arm 84, roller 87 and volute spring 88 etc.Arm 84 rotates centered by axle 86.Axle 86 is fixed on wall 34 by components such as not shown plate or rods.The periphery of axle 86 is provided with volute spring 88.One end of volute spring 88 to be against from arm on pawl 90 outstanding on 84, and the other end of volute spring 88 is against and is fixed on the pawl 89 on wall 34 by components such as not shown plate or rods.In the central authorities of arm 84, be provided with pin 83.Pin 83 insertion is arranged in the groove 85 on rod 18.In the left side of arm 84, be provided with roller 87.Roller 87 can rotate centered by axle 92.In addition, roller 87 contacts with the right flank of block 91 on the top being arranged on offset cam 10.Therefore, even if due to the elastic force of torsion coil spring 12, offset cam 10 will rotate clockwise centered by axle 11, and the rotation of offset cam 10 is also prevented from.

If solenoid 13 drives, then plunger 54 is just pulled to the inside of solenoid 13.So in Figure 26 (B), after the groove 85 due to excellent 18 moves up, the end of groove 85 is against on pin 83, so pin 83 also moves up.So, in Figure 26 (B), arm 84 rotates clockwise centered by axle 86.At this moment, roller 87 rotates centered by axle 92.Therefore, the friction force produced between roller 87 and module 91 is just little.

When card processing unit 1 detects the blocking of card 2, solenoid 13 just drives as mentioned above.Figure 27 represents the state that solenoid 13 has driven.In Figure 27 (B), plunger 54 and rod 18 upwards move side.By the movement of groove 85, pin 83 moves up.Due to the movement of pin 83, arm 84 rotates clockwise centered by axle 86.Because the right side of roller 87 from block 91 is rearwardly kept out of the way, offset cam 10 rotates because of the elastic force of torsion coil spring 12 centered by axle 11, and in Figure 27 (B), the top of offset cam 10 is moved to the right.At this moment, due to the elastic force of volute spring 88, arm 84 will rotate counterclockwise centered by axle 86., due to the elastic force of volute spring 88, the back side of block 91 is contacted, the rotation of blocking extension 84 with roller 87.As shown in Figure 27 (A), because offset cam 10 rotates clockwise centered by axle 11, the outer peripheral portion 9b of offset cam 10 and the surface contact of card 2.At this moment, offset cam 10 is to the surface action pressing force of card 2.

By the surface contact of offset cam 10 with card 2, except above-mentioned pressing force, between card 2 and the outer peripheral portion 9b of offset cam 10, also act on large friction force.Therefore, even if the person of hatching a sinister plot thinks that the card 2 of blocking is transferred to from the insert port 3a of card insertion section 3 by use instrument etc., can not extract easily.

In the state of Figure 27 (A), suppose that the person of hatching a sinister plot wants the situation of being extracted from insert port 3a by card 2 by larger strength.At this moment, because will extract card 2 with larger strength, and due to the friction force between card 2 and offset cam 10, offset cam 10 will rotate clockwise further centered by axle 11.So the outer peripheral portion 9b contacted with card 2, will move to roughly identical with the direction will extracting card 2 direction.This state represents with Figure 28.

In Figure 28, due to offset cam 10, relatively axle 11 is eccentric, and the outer peripheral portion 9b ' of to be therefore distance that is longer than outer peripheral portion 9b contact with card 2 in Figure 27 (A), distance axle 11 be L2 ' contacts with card 2.Distance L2 ' is longer than distance L2.So, larger pressing force acts on the surface of card 2 from offset cam 10, and the friction force between offset cam 10 and card 2 just becomes larger.Therefore, extract card 2 and become more difficult.

Under the state that offset cam 10 applies pressing force to card 2, by arranging the lockable mechanism of the position locking of offset cam 10, can accomplish no matter to push away card from the outside of card processing unit 1 or pull out card, not allowing card 2 move.Figure 29 and Figure 30 is structural drawing when having set up lockable mechanism in prevention mechanism.(A) represents side view in the various figures, and (B) represents front view (FV).Further, in figure (A), (B), eliminate the diagram of supporting tool 97, solenoid 13 and the volute spring 12 etc. stoping mechanism.In addition, in figure (B), the diagram of wall 34, gate 14 and card insertion section 3 etc. is eliminated.In this embodiment, the periphery 9 of offset cam 10 forms teeth portion 108.

Figure 29 represents the state that solenoid 13 does not drive.On wall 34, platform 130 is installed.Setting tool 134 is installed, makes to rotate centered by its axle 138 on platform 130.Setting tool 134 is fixed on the position of Figure 30 (A) the position of offset cam 10.In Figure 29 (B), in the left side of setting tool 134, be provided with pawl 137.In the upside of setting tool 134, be provided with pawl 135.One end of volute spring 131 is arranged on the pawl 133 on the 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, by the elastic force of volute spring 131, effect has the power that setting tool 134 will be made to rotate counterclockwise centered by axle 138.The left side 139 of setting tool 134 is against on 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 represents with profile line.

If card processing unit detects the blocking of card 2, just drive solenoid 13 (with reference to Figure 26).Solenoid 13 1 drives, and in Figure 29 (A), offset cam 10 just rotates clockwise centered by axle 11.Further, the teeth portion 108 of periphery 9 contacts with card 2.State now represents with Figure 30.

In fig. 30, if want to extract card 2, due to the friction force between teeth portion 108 and card 2, offset cam 10 more will rotate clockwise.So, teeth portion 108 can compress card 2 more, is pulled out to prevent card 2.

Because offset cam 10 rotates clockwise, in Figure 30 (A), the bar 19 of offset cam 10 moves to upper right side.Therefore, as shown in Figure 30 (B), bar 19 departs from from the left side 139 of setting tool 134, so setting tool 134 relies on the elastic force of volute spring 131, rotates counterclockwise centered by axle 138.Further, in the position that the pawl 135 of upside contacts with bar 19, the rotation of setting tool 134 stops.So, bar 19 just can not move side downwards.Namely offset cam 10 becomes lockup state.

In this state, then when card 2 is inserted from insert port 3a, due to the friction force between card 2 and teeth portion 108, offset cam 10 will rotate counterclockwise.At this moment, in Figure 30 (A), bar 19 will below be mobile left., as shown in Figure 30 (B), because the pawl 135 of setting tool 134 contacts with bar 19, offset cam 10 can not rotate counterclockwise.Therefore, due to offset cam 10 non rotating, when both having made to push away card 2 from the outside of card processing unit 1, card 2 does not also move.On the other hand, when pulling out card 2, due to the friction force between card 2 and teeth portion 108, offset cam 10 rotates clockwise, and the surface of teeth portion 108 to card 2 compresses more.Therefore, card 2 can not be extracted.

So under the state that teeth portion 108 and card 2 have contacted, no matter push away card from the outside of card processing unit or pull out card, card 2 does not move.So, the card 2 got lodged in card processing unit just can be prevented to be removed.

When removing the lockup state of offset cam 10, in Figure 30 (B), the pawl 137 of setting tool 134 being lifted to upside, makes it rotate clockwise.Further, in Figure 30 (A), by lower beam 19, offset cam 10 is rotated counterclockwise.So, the arm 84 (with reference to Figure 27) of supporting tool 97, rely on the elastic force of volute spring 88, rotate counterclockwise centered by axle 86, roller 87 contacts with the right flank of the block 91 of offset cam 10 (with reference to Figure 26), the position of offset cam 10 is fixed, and gets back to the state shown in Figure 29.

Brief summary of the invention

The problem that invention will solve

On above-mentioned card processing unit in the past, as Figure 26 the explanation done, the pin 83 of arm 84 inserts in the groove 85 of rod 18, if solenoid 13 drives, rod 18 is just mobile, because the end of groove 85 is against pin 83, moved together with rod 18 by pin 83, arm 84 will rotate centered by axle 86.

Here, as what understand in Figure 26 (B), the position of solenoid 13 draft arm 84, the i.e. position of pin 83 are on the line linking the axle 86 as the fulcrum of arm 84 and the roller 87 as the application point of arm 84.Like this, in the structure of the point on the fulcrum of this draft arm 84 and the line of application point, configure and be restricted as the position of the solenoid 13 of driver and direction, such as, solenoid 13 can not be configured in from the position of the position of Figure 26 (B) half-twist to the right.Therefore, even if just there is the position of wanting to change solenoid 13, but in order to not hinder parts or the distribution of surrounding, and solenoid 13 can not be configured in the problem of random position.

In addition, with regard to card processing unit in the past, under the state that solenoid 13 does not drive, when applying vibratory impulse, in order to prevent the engaging between offset cam 10 and supporting tool 97 from departing from (state of Figure 27) and maloperation, be necessary to strengthen the contact force between offset cam 10 and supporting tool 97.Therefore, strengthen the spring force of the torsion coil spring 12 offset cam 10 being applied to clockwise acting force, from the load that the roller 87 of offset cam 10 pairs of arms 84 is in addition large.Thus when removing the locking of offset cam 10, press owing to must overcome this strong spring force barre 19, its operation has just been not easy.Further, in order to reduce the friction of application point on arm 84, being necessary to arrange the roller 87 playing bearing effect, thus having the problem that cost improves.

Summary of the invention

In view of the above problems, the object of the present invention is to provide a kind of card processing unit, can not be configured for by position and direction restriction the driver driving offset cam, and the locking that easily can carry out offset cam is removed, and can reduce costs.

The means of dealing with problems

Card processing unit for the present invention, possesses: card insertion section, inserts the card of the information that records; Abnormal detection mechanism, detects the exception of the card inserted from this card insertion section; And stop mechanism, when this abnormal detection mechanism detects abnormal, stop and take out card from card insertion section.Mechanism is stoped to possess: offset cam, supporting tool and driver.Offset cam, is rotatably arranged, and can not apply the 1st position of pressing force to this card to leaving card and contact with card and conjugate the 2nd position that this card applies pressing force.Supporting tool, is rotatably arranged, and by the engaging with offset cam, this offset cam is supported on the 1st position, by removing the engaging with offset cam, offset cam is conjugated to the 2nd position from the 1st position.Driver, when abnormal detection mechanism detects abnormal, makes supporting tool rotate, to remove the engaging of supporting tool and offset cam.

Also have, in the present invention, supporting tool has and is configured to criss-cross 4 arms, and possess following structure: the centre of gravity place in the 1st plane comprising 4 arms, consistent with the 1st rotation center of the 1st plane, further, comprising the 1st rotation center and centre of gravity place in the 2nd plane orthogonal with the 1st plane, consistent with the 2nd rotation center of the 2nd plane.Further, 1 arm in 4 arms engages with offset cam, and 1 arm in all the other arms and driver link.

If according to such structure, because driver can link with any arm (namely not having the arm of application point) beyond the arm engaged with offset cam in 4 arms, just unlike the past the point on the fulcrum of armite and the line of application point is drawn, and the position become beyond to the point on this line is drawn.Therefore, alleviate the restriction on the position of configuration driven device and direction, the degree of freedom of configuration can be improved.

Also have, due to become no matter the 1st plane and the 2nd plane which on, the structure that its centre of gravity place is all consistent with rotation center, balance can be obtained for fore-and-aft direction, left and right directions and above-below direction, no matter apply vibratory impulse in which direction, all can not produce torque to supporting tool.Therefore, even if the load that offset cam is in addition not large to supporting tool, also the engaging disengaging of offset cam and supporting tool can not be made and maloperation due to vibratory impulse, therefore, strong spring power need not be allowed to be applied on offset cam, and the locking of offset cam is removed operation and is just become easy.

Moreover, because the load of the snap portions (application point) of supporting tool and offset cam is little, as in the past, for reducing friction, roller need not be set on supporting tool, just can reduce costs.

Card processing unit for the present invention, also can be such structure: arm comprise the 1st arm, with the 2nd arm that the 1st arm extends in the opposite direction, 3rd arm orthogonal with the 1st arm and the 2nd arm and with the 3rd arm at contrary the 4th arm upwards extended, 1st arm and driver link, 2nd arm has the counterweight balanced with the 1st arm, 3rd arm is relative to the 1st arm and the 2nd arm, to extending with driver opposite side and engaging with offset cam, 4th arm is relative to the 1st arm and the 2nd arm, homonymy to driver extends, and has the function of the counterweight balanced with the 3rd arm.

Card processing unit for the present invention also can be such structure: the bar operated when offset cam possesses the cam part contacted with card, the holding section engaged with supporting tool and removes the contact of cam part and card.

Card processing unit for the present invention, can also possess in the 2nd position by the lockable mechanism of offset cam locking.This lockable mechanism, comprise can near offset cam bar direction locking direction and leave bar direction releasing direction rotate setting tool.In a preferred embodiment, setting tool has: fastener, the 1st claw and the 2nd claw.When locking offset cam, along with this offset cam is to the movement of the 2nd position, when setting tool rotates to locking direction, the bar of fastener and offset cam engages.In addition, when removing the locking of offset cam, after having made setting tool rotate to releasing direction, when pressing lower beam, promote the 1st claw by this bar, setting tool has rotated to locking direction again.Further, removed at the locking of offset cam, under the state that this offset cam is in the 1st position, during to releasing direction operation setting tool, the 2nd claw abuts with bar, this bar is applied to the power in the direction that offset cam is increased with the engaging power of supporting tool.

If according to such structure, due to offset cam under the state pressing card by locking, therefore, it is possible to stop more reliably from card insertion section take out card.Also have, when offset cam is not by locking, even if mistakenly to releasing direction operation setting tool, because the power making the engaging power between offset cam with supporting tool increase in the bar effect of the 2nd claw to offset cam, therefore offset cam can not be made to depart from the engaging of supporting tool and make offset cam become lockup state, the maloperation stoping mechanism can be prevented.

Card processing unit for the present invention also can be the structure of the projection of the 1st claw be provided with on the bar of offset cam for promoting setting tool.

Invention effect

According to the present invention, a kind of card processing unit can be provided, the driver for driving offset cam is not set by position and restriction ground, direction, and the locking that easily can carry out offset cam be removed, and can reduce costs.

Embodiment:

Below, with reference to accompanying drawing, embodiments of the present invention are described.In the various figures, prosign is used with a part or corresponding part.

First, be described with reference to the general structure of Fig. 1 to the card processing unit of embodiment for the present invention.In FIG, insert detecting sensor 17, this situation of insert port 3a card 2 having been inserted to card insertion section 3 detects.On card 2, record information.When card 2 is magnetic cards, the surface of card 2 possesses magnetic stripe, and this magnetic stripe records information.When card 2 is Contact Type Ic Cards, the surface of card 2 possesses IC contact, possesses the IC chip be connected with IC contact in the inside of card 2.When card 2 is non-contact IC cards, possess antenna and the IC chip of communication in the inside of card 2.On Contact Type Ic Card and non-contact IC card, information record on the ic chip.In explanation below, using Contact Type Ic Card for illustrating as IC-card.

Insert the insertion that detecting sensor 17 1 detects card 2, gate 14 is just opened.Opened by gate 14, card 2 can be sent to the inside of card processing unit 1.The transfer path 5 of transfer card 2, represents with dot-and-dash line.Further, in fig. 26, gate 14 is configured at the upside of transfer path 5, but in FIG, gate 14 is configured at the downside of transfer path 5.

Transfer path 5, is made up of insert port 3a and upper and lower roller 4.Driven by motor 25 (Fig. 2) not shown in FIG, roller 4 rotates.The card 2 one inserted from insert port 3a abuts with roller 4, and the roller 4 of card 2 just by rotating, is transmitted by the inside to card processing unit 1.Card detecting sensor 6,7,8, detects the presence or absence of card 2 on respective position.After card 2 inserts, if card detecting sensor 6 becomes the state not detecting card 2 from the state detecting card 2, gate 14 is just closed.

When the card 2 inserted is magnetic cards, in the transport process of magnetic card, magnetic head 15 reads the magnetic information of magnetic card, or writes magnetic information on magnetic card.When the card 2 inserted is IC-cards, card 2 is sent to the position of regulation.Then, driven by contact solenoid 28 (Fig. 2) for making IC contact 16 decline, IC contact 16 decline and with the IC contact of IC-card.Then, this IC contact 16, from IC-card read information, or on IC-card written information.If read or write end, stop driving with solenoid 28 (Fig. 2) by contact, IC contact 16 rises, and leaves IC contact.If to read the information of card 2 or write terminates, roller 4 with regard to retrograde rotation, to insert port 3a transfer card 2.So the state never detecting card 2 when card detecting sensor 6 becomes the state detecting card 2, and gate 14 is just opened.So, card 2 is sent to the outside of insert port 3a by roller 4.

Near insert port 3a, be provided with the offset cam 60 forming the part stoping mechanism.Offset cam 60, possesses cam part 62 and bar 63 etc., freely can rotate centered by axle 66.About the detailed construction of prevention mechanism comprising this offset cam 60, illustrate below.

As an example of the card exception produced on above-mentioned card processing unit 1, suppose after the insert port 3a of card insertion section 3 juggles things, when card 2 inserts or discharges, card 2 has got lodged in the situation of the inside of transfer path 5.Although want rotating roller 4, when 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 blocking of card 2, and offset cam solenoid 51 (Fig. 2) described later just drives, and accordingly, offset cam 60 just rotates clockwise centered by axle 66.So, due to the cam part 62 of offset cam 60 and the surface contact of card 2, between offset cam 60 and card 2, produce friction force, therefore outwards extract card 2 from insert port 3a and be prevented from.About the detailed action of this situation, illustrate below.

Next, be described with reference to the structure of Fig. 2 to the electricity of card processing unit 1.In fig. 2, each several part of CPU20 control card treating apparatus 1, again from each several part obtaining information.When card 2 is magnetic cards, magnetic head 15 reads magnetic information or writes magnetic information at magnetic stripe in the magnetic stripe of card.When card 2 is IC-cards, the IC contact of IC contact 16 and card, reads information or written information on the ic chip from IC chip.

Motor 25, is mechanically connected with roller 4 (Fig. 1), and by the driving of this motor 25, roller 4 rotates.Rotary encoder 26, as an example of abnormal detection mechanism in the present invention, detects the rotating speed of motor 25.Whether card detecting sensor 6,7,8, detect the existence blocking 2 on the position of specifying of transfer path 5 (Fig. 1).Insert detecting sensor 17, whether the existence at insert port 3a place card 2 is detected.Each sensor 6,7,8,17, if detect the existence of card 2, is just switched to ON state from OFF state.Gate solenoid 27 is the solenoids for switch gate 14.Offset cam solenoid 51 is the solenoids for making offset cam 60 rotate.Contact solenoid 28 is the solenoids for making IC contact 16 move up and down.

ROM21, stores the running program of CPU20.RAM22, the information temporarily storing the controling parameters controlling each several part and obtain from each several parts such as magnetic head 15 and IC contacts 16.Further, RAM22, temporarily stores and writes the information in blocking by magnetic head 15 or IC contact 16.Department of Communication Force 24, communicates with epigyny device.As the example of epigyny device, there is the ATM being equipped with card processing unit 1.Department of Communication Force 24 sends to epigyny device the information that reads from card 2 and represents the failure message etc. that card 2 has blocked etc.In addition, Department of Communication Force 24, receives the kind of information etc. that will write the information of card 2 and the card 2 as handling object from epigyny device.

Below, to stop mechanism and lockable mechanism to be attached most importance to, with reference to accompanying drawing, the detailed construction of card processing unit 1 is described.

Fig. 3 represents the structure near card insertion section 3, for simplicity, represents with the state removing the upper wall of insert port 3a.Further, the diagram of the insertion detecting sensor 17 of Fig. 1 is eliminated.Card insertion section 3 is made up of the block of resin module, as shown in Figure 1, is arranged at before card processing unit 1.Card 2 is inserted in the insert port 3a that card insertion section 3 is formed with direction shown in arrow.At the rear of card insertion section 3, be provided with wall portion 40.In the side below of wall portion 40, be equipped and stop mechanism 100, in the front face side of wall portion 40, be equipped with lockable mechanism 200.

Mechanism 100 is stoped to possess: offset cam 60, supporting tool 53 and offset cam solenoid 51.Offset cam solenoid 51 is embodiments for driver in the present invention.

Offset cam 60, rotatably arrange centered by axle 66 (Fig. 4 (D)), possess: base portion 61, the cam part 62 be installed on this base portion 61, with base portion 61 shape all-in-one-piece bar 63 and the holding section 64 that is fixed on base portion 61.Base portion 61, cam part 62 and bar 63 are made up of metal, and holding section 64 is made up of resin.In cam part 62, form teeth portion 65.Axle 66 is fixed on not shown framework.Further, though do not illustrated in the diagram, on offset cam 60, torsion coil spring (symbol 69 of Fig. 8 (B)) is installed, the clockwise acting force doing centered by order to axle 66 to offset cam 60 by this spring.

Fig. 5 represents that offset cam 60, Fig. 5 (A) is planimetric map, and Fig. 5 (B) is front view (FV), and Fig. 5 (C) is side view.The same with the offset cam 10 of Figure 26, the distance from the axle 66 of offset cam 60 to the periphery of cam part 62 is not equidistant, and axle 66 is eccentric relative to the periphery of cam part 62.As shown in Fig. 5 (C), near the top of bar 63, projection 67 outstanding is downwards arranged integratedly.Further, in the end of axle 66, E type circle 68 is installed.

As aftermentioned, rotated centered by axle 66 by offset cam 60, cam part 62 just can to position (position of Figure 10 (the D)) displacement of the position (position of Fig. 8 (D)) and contact card 2 of leaving card 2.

Get back to Fig. 4, supporting tool 53 is described.Supporting tool 53, as 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 freely can rotate centered by axle 57.Axle 57 is fixed on not shown framework.

In 4 arm 53a ~ 53d, the 1st arm 53a is linked by pin 52 (Fig. 4 (A)) and the offset cam plunger 58 (Fig. 4 (C)) of solenoid 51.2nd arm 53b and the 1st arm 53a extends round about, has the counterweight 56 balanced with the 1st arm 53a.Here, counterweight 56 is made up of cylindrical metal, is contained in the cylindrical portion that the 2nd arm 53b end is formed.The 3rd arm 53c orthogonal with the 1st and the 2nd arm 53a, 53b, relative to these two arms 53a, 53b, extend to offset cam solenoid 51 opposite side, top ends engages with the otch 64a that the holding section 64 of offset cam 60 is formed.The 4th arm 53d extended round about with the 3rd arm 53c, relative to the 1st and the 2nd arm 53a, 53b, extends to the homonymy of offset cam with solenoid 51, has the function of the counterweight balanced with the 3rd arm 53c.

Supporting tool 53, by between itself and the volute spring 59 of offset cam between solenoid 51, is applied in the acting force counterclockwise centered by axle 57 in Fig. 4 (A).As aftermentioned, rotated centered by axle 57 by supporting tool 53, the 3rd arm 53c just can conjugate to the position engaged with offset cam 60 (position of Fig. 8 (A)) and the position departed from the engaging of offset cam 60 (position of Figure 10 (A)).

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

Below, be described with reference to the balance of Fig. 7 to supporting tool 53.Due to the key diagram that Fig. 7 is equilibrium principle, therefore supporting tool 53 pattern is illustrated.Fig. 7 (A) is planimetric map, and Fig. 7 (B) is front view (FV).

In Fig. 7 (A), X-coordinate and Y-coordinate are set as the direction of figure, the plane comprising 4 arm 53a ~ 53d is called XY plane.This XY plane is equivalent to the 1st plane in the present invention.Now, in XY plane, rotation center when will be rotated along arrow a direction by supporting tool 53 is as the axle center of axle 57.This rotation center is just equivalent to the 1st rotation center in the present invention.

Here, as above-mentioned, for the 1st arm 53a and the 2nd arm 53b, on the 2nd arm 53b, be provided with the counterweight 56 balanced with the 1st arm 53a.In addition, the 3rd arm 53c and the 4th arm 53d, the 4th arm 53d are had to the function of the counterweight balanced with the 3rd arm 53c.Thus, in 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), be the direction of figure by Z setting coordinate, will axle 57 be comprised and the plane orthogonal with XY plane is called XZ plane.This XZ plane is just equivalent to the 2nd plane in the present invention.At this moment, in XZ plane, rotation center when supporting tool 53 will rotate to arrow b direction is exactly the some P on the axle center of axle 57.

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

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

Return Fig. 4, below lockable mechanism 200 is described.As shown in Fig. 4 (B), lockable mechanism 200, possesses: setting tool 70, support axle 78 that this setting tool 70 rotates freely, apply the torsion coil spring 79 of elastic force and the framework 80 of stationary shaft 78 to setting tool 70.

Setting tool 70, has: the part 2 72 form arciform part 1 71, extending from this part 1 71 to the direction parallel with axle 78 and from this part 2 72 to the 3rd part 73 that vertical direction extends.In part 1 71, be provided with: for the operating sheet 74 making setting tool 70 rotate, the fastener 75 of bar 63 engaging offset cam 60 and the claw 77 that can abut with bar 63 when locking is removed.In addition, in the 3rd part 73, be provided with the claw 76 that can be promoted by the projection 67 of bar 63.The 2nd claw that claw 76 is equivalent to the 1st claw in the present invention, claw 77 is equivalent in the present invention.

Part 1 71 and the 3rd part 73, the axle 78 be fixed on framework 80 runs through.So, setting tool 70 just can centered by axle 78, the direction (counterclockwise) to the bar 63 of the close offset cam 60 as locking direction and the direction (clockwise direction) leaving bar 63 rotation as releasing direction.On the fastener 75 of part 1 71, formative gear shape concavo-convex.Torsion coil spring 79, one end is supported on framework 80, and the other end and the pin 81 (Fig. 4 (A)) be fixed in part 1 71 link.In Fig. 4 (C), setting tool 70, to be applied in centered by axle 78 acting force counterclockwise by this torsion coil spring 79.

Below, with reference to Fig. 8 ~ Figure 13, be described stoping the action of mechanism 100 and lockable mechanism 200.

Under normal conditions (time standby), mechanism 100 is stoped to be in the state shown in Fig. 8.In fig. 8, (A) is planimetric map, and (B) is oblique view, and (C) is front view (FV), and (D) is side view.In addition, in fig. 8, the diagram of lockable mechanism 200 is eliminated.

Under the state of Fig. 8, offset cam solenoid 51 is not operating, and the otch 64a that the top of the 3rd arm 53c of supporting tool 53 and the holding section 64 of offset cam 60 are formed engages.Further, supporting tool 53, by the elastic force of volute spring 59, be applied in acting force counterclockwise centered by the axle 57 in Fig. 8 (A), thus above-mentioned fastening state is maintained.

On the other hand, offset cam 60, although be subject to the power clockwise centered by axle 66 by torsion coil spring 69 (Fig. 8 (B)), as above-mentioned, because the top of the 3rd arm 53c engages with the holding section 64 of offset cam 60, can not rotate clockwise.Therefore, offset cam 60 is in the position shown in Fig. 8 (D), and this position is that cam part 62 is left card 2 and card 2 do not applied to the position of pressing force, is equivalent to the 1st position in the present invention.

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

In the state of figure 9, setting tool 70 to be applied in centered by axle 78 acting force counterclockwise by torsion coil spring 79, and part 1 71 is against the side of the bar 63 of offset cam 60.Thus, setting tool 70 can not continue to rotate counterclockwise.

According to method described later, if detect the blocking of card 2, mechanism 100 is stoped just to become the state shown in Figure 10.In Fig. 10, (A) is planimetric map, and (B) is oblique view, and (C) is front view (FV), and (D) is side view.Further, the diagram of lockable mechanism 200 is eliminated in Fig. 10.

Under the state of Figure 10, offset cam solenoid 51 works, and the 1st arm 53a of supporting tool 53, is drawn by the plunger 58 of offset cam solenoid 51 by pin 52.Thus supporting tool 53 overcomes the elastic force of volute spring 59, rotate clockwise centered by axle 57 in Figure 10 (A).Therefore, the top of the 3rd arm 53c, the otch 64a formed from the holding section 64 of offset cam 60 departs from, and the 3rd arm 53c is removed with the engaging of offset cam 60.

Consequently, offset cam 60, due to the elastic force of torsion coil spring 69, rotates clockwise centered by axle 66, to the position displacement shown in Figure 10 (D).This position is that cam part 62 contacts with card 2 and card 2 applied to the position of pressing force, is equivalent to the 2nd position in the present invention.

In this state, the same with the situation of Figure 27, more want to be extracted by card 2 from insert port 3a, the pressing force of cam part 62 to card 2 is stronger, extracts card 2 and just becomes more difficult.Particularly, the teeth portion 65 that cam part 62 is formed bites the surface of card 2, thus, to be extracted by card 2 just more difficult for from insert port 3a.

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

Along with offset cam 60 is to the position displacement shown in Figure 10 (D), bar 63 pops up.Therefore, the setting tool 70 of lockable mechanism 200, due to the acting force of torsion coil spring 79, from position (locking direction) rotation further counterclockwise of Fig. 9 (C), and as shown in Figure 11 (C), stop in the position abutted with bar 63.At this moment, also by being fixed on the pin 81 on setting tool 70, with abutting of the end of the guiding groove 80a formed on framework 80, limit the rotation of setting tool 70.

In this state, a part for the fastener 75 of setting tool 70, engages with bar 63.Thus, just can not remove the cam part 62 of offset cam 60 and the contact of card 2 by lower beam 63.The position of offset cam 60 shown in Figure 10 (D) is by locking.Like this, can prevent from more reliably from insert port 3a, card 2 being extracted.In addition, under the state of Figure 11, between fastener 75 and bar 63, also can slightly gap.Said in the present invention " locking ", also comprises this situation.

When removing the locking of offset cam 60, perform operation below.Figure 12 and Figure 13 is the key diagram of this situation.In the various figures, (A) is planimetric map, and (B) is oblique view, and (C) is front view (FV), and (D) is side view.Further, each figure is omitted the diagram of offset cam solenoid 51 and supporting tool 53.

First, as shown in figure 12, hold the operating sheet 74 of setting tool 70, make setting tool 70 (releasing direction) rotation clockwise centered by axle 78.This rotation, although the elastic force of torsion coil spring 79 will be overcome on the way, but the time point making setting tool 70 turn to a certain degree, torsion coil spring 79 carries out snap-fastener (snap) action, and its resilient force makes setting tool 70 rotate clockwise.Therefore, after making setting tool 70 turn to the position shown in Figure 12 (C), even if remove the holding to operating sheet 74, setting tool 70 also can not (locking direction) rotate counterclockwise, and static in this position.Further, on the position of Figure 12 (C), due to the pin 81 of setting tool 70 and the end abutment of the guiding groove 80a of framework 80, being rotated further of setting tool 70 is limited.

Next, as shown in figure 13, the bar 63 of offset cam 60 is pressed.At this moment, the fastener 75 due to setting tool 70 moves back the side to bar 63, and can not hinder, therefore, it is possible to pressed by bar 63 by setting tool 70.Along with pressing of bar 63, offset cam 60, rotates counterclockwise centered by axle 66.Therefore, as shown in Figure 13 (D), cam part 62 is left from card 2.

If press lower beam 63 further from the state of Figure 13, due to the claw 76 formed in the 3rd part 73 of setting tool 70, promoted by the projection 67 that bar 63 is arranged, setting tool 70 just starts centered by axle 78, and (locking direction) rotates counterclockwise.So if press finally by bar 63, setting tool 70 resets to the position of Fig. 9.

Like this, by being provided with projection 67 on bar 63, and promote the structure of claw 76 by 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, and operability improves.

On the other hand, along with pressing of bar 63, if offset cam 60 rotates counterclockwise, then the top of the 3rd arm 53c of supporting tool 53 is just by 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.

By above-mentioned operation, the locking of offset cam 60 is removed, and stop mechanism 100 to get back to the state of Fig. 8, lockable mechanism 200 gets back to the state of Fig. 9.

According to above-mentioned embodiment, offset cam solenoid 51, can link with any arm beyond the 3rd arm 53c engaged with offset cam 60 in the middle of 4 arm 53a ~ 53d.In the present embodiment, offset cam solenoid 51 links with the 1st arm 53a, but also offset cam solenoid 51 and the 2nd arm 53b or the 4th arm 53d can be linked.Such as, when being linked with solenoid 51 and the 2nd arm 53b by offset cam, just counterweight 56 is set on the 1st arm 53a.

Due to the arm beyond the 3rd arm 53c, it is the arm not having application point (part engaged with offset cam 60), therefore, if offset cam solenoid 51 and these arms linked, the position that this solenoid 51 just becomes beyond to the point on the line of the fulcrum being positioned at armite (axle 57) and application point is drawn.Therefore, with in the past such, the situation that point on the fulcrum of armite and the line of application point draws is compared, the position of configuration offset cam solenoid 51 and the restriction in direction are relaxed, the degree of freedom of configuration can be improved.

In addition, in the present embodiment, as with Fig. 7 the explanation done, apply vibration due to upper in any direction or impact, all can not produce torque to supporting tool 53, even if so offset cam 60 does not apply large load to supporting tool 57, also do not worry due to vibratory impulse, and stop mechanism 100 maloperation after the engaging of offset cam 60 and supporting tool 57 is departed from.Thus, due to the elastic force of torsion coil spring 69 (Fig. 8 (B)) need not be increased, therefore very little just passable to the acting force of offset cam 60 applying.Consequently, the power pressing the bar 63 of 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 the present embodiment, because the load of the snap portions (application point) of supporting tool 57 and offset cam 60 is little, therefore need not as in the past, supporting tool 57 being arranged for reducing the roller 87 (Figure 26) rubbed, only allowing the otch 64a that the top of the 3rd arm 53c and the holding section 64 of offset cam 60 are formed engage.Like this, just can omit roller and reduce costs.

In addition, in the present embodiment, lockable mechanism 200 also application of some to improve.In lockable mechanism in the past, when offset cam is not by locking, if mistakenly to releasing direction operation setting tool, rotate and the problem of maloperation (becoming lockup state) with regard to there is offset cam.If specifically described, be exactly that if firmly upwards pushed away by the pawl 137 of setting tool 134, then pawl 137 abuts with bar 19 in Figure 29 (non-lockup state), offset cam 10 is subject to the clockwise power centered by axle 11.If this power is large, the fastening state of offset cam 10 and arm 84, from the state of Figure 26 to the state transfer of Figure 27, offset cam 10 rotates clockwise, and becomes lockup state.

And in the lockable mechanism 200 of present embodiment, at offset cam 60 not by under the state of Fig. 9 of locking, when being operated to releasing direction (clockwise direction) by setting tool 70 mistakenly, the claw 77 of setting tool 70 abuts with bar 63.At this moment, because claw 77 is shapes of tip, the edge below the conical surface of claw 77 and bar 63 is linear contact lay.Further, if continued to releasing direction operation setting tool 70, although claw 77 pairs of bars 63 are applied with stronger power, this power serves the effect of the engaging power strengthening offset cam 60 and supporting tool 53.

That is, the edge below the conical surface catch bar 63 of claw 77 as a result, bar 63 is in Fig. 9 (C), except power upwards, be also subject to the power left of claw 77.Due to this power left, in Fig. 8 (A), bar 63 will conjugate to the left.Thereupon, due to holding section 64 also to the left, the reverse direction that is to the direction departed from the engaging of the 3rd arm 53c conjugates, so the 3rd arm 53c becomes firmer with the engaging of holding section 64.Consequently, even if to releasing direction operation setting tool 70, offset cam 60 also can not become lockup state (Figure 10) because of maloperation.

Below, from card processing unit 1, the card 2 inserted is carried out to reading and the write of information, be described to the process that card 2 is discharged.Further, also to the insertion at card 2 or when discharging, process during card 2 blocking is described.

Figure 14 is the process flow diagram representing the outline blocking process on card processing unit 1.In step sl, CPU20 is by the kind of Department of Communication Force 24 from epigyny device receiving card 2.Here, suppose magnetic card and the Contact Type Ic Card kind as card 2.Next, in step s 2, whether CPU20 is that magnetic card judges to the kind of the card 2 received.When being judged to be magnetic card, in step s3, CPU20 carries out takeing in process and reading the process of magnetic information from magnetic card of magnetic card.Then, in step s 4 which, CPU20 carries out the process to magnetic card write magnetic information.Then, in step s 5, CPU20 carries out the discharge process of card 2.About card process detailed, aftermentioned of step S3, S4, S5.

On the other hand, in step s 2, when the kind judging the card 2 received is not magnetic card, in step s 6, whether the kind of CPU20 to the card 2 received is that IC-card judges.When being judged to be IC-card, in the step s 7, CPU20 carries out takeing in process, reading information and the process to IC-card written information from IC-card of IC-card.Then, in step s 5, CPU20 carries out the discharge process of card 2.About card process detailed, aftermentioned of step S7.

In addition, in step s 6, when the kind judging the card 2 received is not IC-card, CPU20 does not carry out every process of step S7 and enters step S5, carries out the discharge process of card 2.Namely this is the card owing to being inserted into is not the IC-card that the magnetic card supposed neither suppose, thus can not carry out card process.

Figure 15 is the detailed process flow diagram takeing in the reading process of process and magnetic card representing magnetic card in the step S3 of Figure 14.In step S20, whether CPU20 detects card 2 (magnetic card) judge to the insertion of insert port 3a inserting detecting sensor 17.Figure 20 represents that card 2 has been inserted into the state of insert port 3a.In this state, the front end due to card 2 does not also arrive the position of inserting detecting sensor 17, and therefore gate 14 is closed.

If insert the insertion that detecting sensor 17 detects card 2, then CPU enters step S21 below.In the step s 21, CPU20 drives gate solenoid 27.So, as shown in figure 21, transfer path 5 is opened by gate 14.Figure 21 represents that card 2 has been inserted into the state of card processing unit 1 inside.Then, in the step S22 of Figure 15, the rotating forward that CPU20 starts motor 25 drives.Driven by the rotating forward of motor 25, each roller 4 be connected with motor 25, rotate towards the direction (forward direction) that card 2 is transmitted toward the inside of card processing unit 1.So, from its front end is inserted into and abuts time point with the roller 4 nearest from insert port 3a, card 2, just by each roller 4, is transmitted over certain speed to the right by along transfer path 5.In the transport process of card 2, magnetic head 15 reads the magnetic information of record on card 2.

CPU20, the rotating speed of the motor 25 obtained based on the output from rotary encoder 26, by carrying out FEEDBACK CONTROL, keeps fixing by the rotating speed of motor 25.Stop the driving of motor 25 in the step S28 of Figure 15 before, CPU20 controls, to make motor 25 rotate forward driving continuously with certain speed.

In step S23, whether CPU20 exports the rotating speed of motor 25 termly rotary encoder 26 and judges.Such as, CPU20, sends driving instruction accordingly with to motor 25, judges the rotation whether rotary compiler 26 detects motor 25.If rotary encoder 26 output speed termly, card 2 is just transmitted with certain speed.If rotary encoder 26 not output speed (if or not having the output of rotary encoder 26) termly, then block 2 and just block.That is, in step S23, whether card 2 is blocked and judges.If card 2 does not block, then enter step S24, if card 2 blocks, then enter step S29.

In step S24, CPU20 by magnetic head 15, in the magnetic stripe of the card 2 transmitted with certain speed, read magnetic information, and make this information be stored into RAM22.Until the driving of motor 25 stops, the process of step S24 is carried out continuously.

In step s 25, whether CPU20 detects card 2 to card detecting sensor 6 and judges.When card detecting sensor 6 detects card 2, return the process of step S23.During card detecting sensor 6 continues to detect card 2, whether CPU20 continues to block card 2 to judge.That is, whether CPU20 is by repeating the process of step S23, S24, S25, block judge card 2.Figure 22 represents that card detecting sensor 6 detects card 2, and also have, magnetic head 15 contacts with card 2 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 has been in by insert port 3a, is incorporated into the state of the inside of card processing unit 1.At this moment, enter step S26, CPU20 stops the driving of gate solenoid 27.So, gate 14 is closed.The position of the card 2 when Figure 23 represents that card detecting sensor 6 can't check card 2, also have, the gate driving of solenoid 27 stops, and the state of gate 14 closedown.

If the gate driving of solenoid 27 stops, in step s 27, whether CPU20 just detects card 2 to card detecting sensor 8 judges.There is the existence of card 2 in the position of card detecting sensor 8, mean that card 2 entirety is by magnetic head 15.Figure 24 represents the position of the front end of card 2 to Dacca detecting sensor 8, and the rear end of card 2 is by the state of magnetic head 15.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, the magnetic information be stored on RAM22, by Department of Communication Force 24, sends to epigyny device by CPU20.Like this, the reading process of blocking the magnetic information of 2 terminates.

On the other hand, in step s 27, when card detecting sensor 8 does not detect card 2, be in the state that magnetic head 15 contacts with card 2.In other words, be that the magnetic information of card 2 not yet reads complete state.At this moment, CPU20 returns step S23, proceeds the transmission of the card 2 performed by the driving of motor 25, and the reading process of the magnetic information of the card 2 performed by magnetic head 15.

, suppose the person of hatching a sinister plot here, want to juggle things on card processing unit 1, get lodged on transfer path 5 to make card 2.Represent the position of the card 2 when card 2 blocks in fig. 25.At this moment, although CPU20 exports rotate instruction to motor 25, rotary encoder 26 does not but detect the rotating speed of motor 25.Therefore, CPU20, in the step S23 of Figure 15, is judged to be that rotary encoder 26 does not regularly export the rotating speed of motor 25.So in step S29, CPU20 carries out card taking and stops process.About the content of the process of step S29, aftermentioned.Then, CPU20 as shown in figure 14, forces to terminate the process of (abnormal ending) card.

In the process flow diagram shown in Figure 15, as step S23 the explanation done, when rotary encoder 26 not termly output speed time, card taking will be carried out and stop process.In addition, also can be, only when rotary encoder 26 does not export rotation speed termly and card detecting sensor 6 detects card 2, just carry out card taking and stop process.The situation of the latter, just carries out card taking and stops process when card 2 is present in the position of card detecting sensor 6.

Figure 16 represents that card taking stops the process flow diagram of the step of process in the step S29 of Figure 15.In step s 30, CPU20 drives offset cam solenoid 51.So, as Figure 10 the explanation done, offset cam 60 rotates centered by axle 66, and the periphery (teeth portion 65) of cam part 62 contacts with card 2.So, take out card 2 from insert port 3a to be prevented from.Further, in step S31, CPU20, by Department of Communication Force 24, just represents that card 2 has got lodged in the failure message of the meaning on transfer path 5, gets in touch with epigyny device.

Figure 17 is the detailed process flow diagram representing magnetic card write process in the step S4 of Figure 14.When the process of the step S3 of Figure 14 terminates, as shown in figure 24, the right-hand member that 2 stop at transfer path 5 is blocked.In order to card 2 being sent to the insert port 3a of transfer path 5, in step s 40, CPU20 starts the reverse driving of motor 25.Driven by the reverse of motor 25, each roller 4 be connected with motor 25, rotate to the direction (reverse direction) that card 2 is transmitted toward insert port 3a side.So, block 2 to be transmitted over left by along transfer path 5.

In step S41, if card detecting sensor 6 detects card 2, then in step S42, CPU20 drives gate solenoid 27.So, gate 14 is opened.Thus card 2 is sent to insert port 3a for the time being, can write magnetic information in the middle of the process below from the front end of card 2.At this moment the position of card 2 is positions as shown in figure 22.In addition, by lengthening the transfer path 5 of card processing unit 1, gate 14 need not be opened, just card 2 can be sent to the position that can write magnetic information from the front end of card 2.

In the step S43 of Figure 17, if insert detecting sensor 17 to detect card 2, in step S44, the rotating forward that CPU20 starts motor 25 drives.Then, in step S45, CPU20, by Department of Communication Force 24, receives the information of write magnetic card, and is stored in RAM22 from epigyny device.Next, CPU20, based on the information be stored in RAM22, to the card 2 in transmission, writes magnetic information by magnetic head 15.The write of magnetic information, during CPU20 sends write signal to magnetic head 15, carries out continuously.

In step S46, when card detecting sensor 6 can't check card 2, do not exist at the position card 2 of gate 14.Thus in step S47, CPU20 stops the driving of gate solenoid 27.Like this, gate 14 is closed.At this moment blocking the position of 2, is the position shown in Figure 23.So card 2 is transmitted by continuation, 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.Now blocking the position of 2, is the position shown in Figure 24.Then, CPU20 terminates the write process of the magnetic information to card 2, enters the step S5 of Figure 14, carries out the discharge process of card 2.Further, receive period of information of write card 2 from epigyny device about above-mentioned CPU20, as long as before the write undertaken by magnetic head 15 in the step S45 of Figure 17 started, when can.

Figure 18 represents that the detailed process flow diagram of process discharged by card in the step S5 of Figure 14.Process finish time in the step S4 of Figure 14, as shown in figure 24, card 2 is parked in the right-hand member of transfer path 5.In order to be transmitted the insert port 3a side of card 2 to transfer path 5, and discharged by card 2, in the step 60 of Figure 18, the reverse that CPU20 starts motor 25 drives.Driven by the reverse of motor 25, each roller 4 be connected with motor 25, rotate to the direction (reverse direction) that card 2 is transmitted toward insert port 3a side.Like this, block 2 to be transmitted over left along transfer path 5.Before in step S65 described later, the driving of motor 25 stops, the reverse of motor 25 drives to be carried out continuously.

When card 2 is sent to insert port 3a side, in step S61, when card detecting sensor 6 detects card 2, by the card 2 that transmits near insert port 3a.So in step S62, CPU20 drives gate solenoid 27.So, gate 14 is opened, and just the card 2 on transfer path 5 can be discharged from insert port 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, whether can block card 2 and judge.

In step S63, when judging that rotary encoder 26 does not export the rotating speed of motor 25 termly, when being namely judged to be that card 2 blocks, CPU20 is by the flow process of above-mentioned Figure 16, and the card taking performing step S29 stops process.Then, CPU20 forces to terminate the process of (abnormal ending) card.

On the other hand, in the step S63 of Figure 18, when judging that rotary encoder 26 exports the rotating speed of motor 25 termly, when being namely judged to be that card 2 does not block on transfer path 5, in step S64, CPU20 judges whether have passed through the stipulated time detecting card 2 from card detecting sensor 6.At this moment, card 2, by the rotation of roller 4, is transmitted to insert port 3a by with certain speed.Thus, from the front end of the discharge direction of card 2 by the position of card detecting sensor 6, to the rear end of card 2 by the time from the roller 4 that insert port 3a is nearest, be predetermined.Therefore, this time is set as the above-mentioned stipulated time.When there is not the exceptions such as card 2 blocks on card processing unit 1, in step S64, if stipulated time process, because card 2 has terminated by all rollers 4, therefore in step S65, CPU20 stops 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, in step S64, if without the stipulated time, because card 2 does not also terminate by all rollers 4, therefore CPU20 proceeds the transmission of the card 2 performed by roller 4.

In the middle of above-mentioned example, be stop the driving of motor 25 by the measurement time, but in addition, also can increase the quantity of card detecting sensor on transfer path 5, when card 2 is by the position of specifying, 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 judges.When inserting detecting sensor 17 and detecting card 2, owing to existing at insert port 3a place card 2, then wait for that card 2 is removed.When user takes out card 2 from insert port 3a, when insertion detecting sensor 17 can't check card 2, in step S67, CPU20 stops the driving of gate solenoid 27, and like this, gate 14 is closed, and card is discharged process and terminated.

Figure 19 represents that IC-card takes in the detailed process flow diagram that process, IC-card reading process and IC-card write process in the step S7 of Figure 14.As shown in figure 20, when the process of the step S2 of Figure 14 terminates, the front end being in card 2 (IC-card) is inserted into the state of insert port 3a.

In the step S70 of Figure 19, whether CPU20 detects card 2 judge to the insertion of insert port 3a inserting detecting sensor 17.If insert the insertion that detecting sensor 17 detects card 2, in step S71, CPU20 drives gate solenoid 27.So, gate 14 is opened, and just card 2 can be inserted into the inside of card processing unit 1.Then, in step S72, the rotating forward that CPU20 starts motor 25 drives.Driven by the rotating forward of motor 25, each roller 4 be connected with motor 25, rotate to the direction (forward direction) that card 2 is transmitted toward card processing unit 1 inside.Like this, block 2 to be transmitted over to the right by 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, whether can block card 2 and judge.

In step S73, when judging that rotary encoder 26 does not export the rotating speed of motor 25 termly, when being namely judged to be that card 2 blocks, CPU20 is by the flow process of above-mentioned Figure 16, and the card taking performing step S29 stops process.Then, CPU20 forces end-card process (abnormal ending).

On the other hand, in step S73, when being judged to be that rotary encoder 26 exports the rotation speed of motor 25 termly, namely judge that card 2 is not when transfer path blocks, in step S74, whether CPU20 detects card 2 to card detecting sensor 7 judges.The position of setting card detecting sensor 7, with make the front end of the card 2 of card insertion direction to Dacca detecting sensor 7 position when, the position of the IC contact arrival IC contact 16 of card 2.

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

In step S77, CPU20 drives contact solenoid 28, and IC contact 16 is declined.So, IC contact 16 and the IC contact blocking 2.Then, in step S78, CPU20, by IC contact 16, reads information from the IC chip of card 2.CPU20 is stored into RAM22 the information read.Then, CPU20, by Department of Communication Force 24, sends the information be stored in RAM22 to epigyny device.

Then, CPU20, by Department of Communication Force 24, receives written information from epigyny device.In addition, CPU20 is stored into RAM22 this information received.Then, in step S79, CPU20, the written information be stored in RAM22, is write in the IC chip of card 2 by IC contact 16.If write terminates, in step S80, CPU20, by stopping the contact driving of solenoid 28, makes IC contact 16 rise.So, IC contact 16 leaves from the IC contact of card 2.Then, CPU20 enters the step S5 of Figure 14, carries out the discharge process of card 2.
