In addition, in the present embodiment, drive source 5 uses electromagnet, and its starting time shortens, but high speed motion.
For preventing the improper card shape medium 4 of usurping, described card locking device 10 has following 2 lock functions as the main aim of the present invention.Its 1 lock function is, attempts occasion that card shape medium 4 that desire forces to be detained extract bad behavior person, contends with withdrawal force and stop and block the function that shape medium 4 move and are locked being detained the position, extracts and prevents that locking mechanism from playing a role; Another lock function is, apply push-on force on the contrary, attempt to take out the occasion of card shape medium 4 with the withdrawal force alternating action doggedly, contend with the power of pushing back on the contrary and stop and block the function that shape medium 4 move and are locked being detained the position to card shape medium 4 bad behavior person, push back and prevent that locking mechanism from playing a role.The following describes two locking mechanisms.
At first,, extract and prevent that locking mechanism has the fixed frame 11 that fixedly is located at body housing 2 inside, and to have the alleged movable link of elongated the present invention that can be done to move back and forth by this fixed frame 11 guided slidable be movable framework 12 as Fig. 2～shown in Figure 5.The leading section 12b of movable framework 12 (with reference to the enlarged drawing in the circle among Fig. 4) is connected with an end of conversion rod 13 with connecting pin 14, and the other end of this conversion rod 13 is that securing rod 20 is connected with the alleged locking component of the present invention by connecting pin 15 rotationally.Movable framework 12 slides from the normality position (reset position) of Fig. 2 with being fixed framework 11 guiding, can advance along the prescribed stroke distance like that shown in Fig. 3 arrow.As described later, movable framework 12 is subjected to the application of force from normality position forward direction of force application spring 31 (with reference to Fig. 6), and the holding section 6a by clamping device 6 overcomes the elastic force of this force application spring 31 and engages with the movable holding section 12b of framework 12 in the normality position and to be stopped.
Clamping device 6 is being when rotate at the center with pin 6b, and is chimeric with the pin 5a on the output shaft of the electromagnet that is located at drive source 5, and then moving of the output shaft of drive source 5 and moving.In addition, clamping device 6 is provided with the mobile spring 40 that gives the application of force to the output shaft of electromagnet.
Clamping device 6 is subjected to moving from the power of described drive source 5, plays the card of movable framework 12 is only removed and utilized force application spring 31 and make it carry out the function of forward motion.That is, this advance and retreat action of movable framework 12 passes to conversion rod 13 as rotational action, is transformed into the rotational action of securing rod 20 by this conversion rod 13, constitutes bar linkage structure.
In the present embodiment, owing to have elongated movable framework 12 and securing rod 20 be configured in card inserting mouth 3 sides rotationally, so in the space of configurable body housing 2 in existing card reader 1, can prevent card reader 1 maximization by conversion rod 13.
Securing rod 20 is to extract the main member that prevents in the locking mechanism, and as shown in Figure 4 and Figure 5, whole bar body 21 forms the such shape of ratchet.The position of the central portion of bar body 21 or close front end is connected on the other end of conversion rod 13 with described connecting pin 15, and the base end part of bar body 21 turns the earth's axis by fulcrum pin 17 and is bearing on the carriage 18 of being located at body housing 2 sides.Therefore, bar body 21 is subjected to the rotating force from conversion rod 13, can make positive rotation around the axial counter clockwise direction of fulcrum pin 17, also can do despining to clockwise direction.Along the periphery of this bar body 21 leading sections and form jagged locking teeth 22 as the alleged fastener of the present invention.17 distance is to become big from a distolateral locking teeth 22a gradually to another distolateral locking teeth 22b from locking teeth 22 to fulcrum pin, that is to say, with fulcrum pin 17 is the radius of gyration R of center of rotation, be from the radius of gyration R1 of locking teeth 22a to the radius of gyration R2 of locking teeth 22b become gradually megarelief become R1＜...＜R2.
In addition, the bar body 21 of securing rod 20 is the stepped constructions that are made of multi-disc, have the side plate 23 that forms with thick slightly steel plate in the both sides of width dimensions direction, the folded multi-disc of side plate 23 chien shih sheet steel flaggies constitutes the tooth plate 24 that roughly forms identical shaped similar shape size.One distolateral to another distolateral described locking teeth 22a, 22b of being formed with from periphery on the piecemeal tooth plate 24, the increment of this locking teeth 22a, 22b forms than outstanding slightly laterally such size and the shape of the locking teeth 22 that is formed at side plate 23 peripheries.By with stepped construction bar body 21 being formed wide cut like that, locking teeth 22a, 22b just can be along card Width (the card direction of travel is vertical direction relatively) with wide cut or a plurality of points and the surperficial butt that blocks shape medium 4, just can stop it to move reliably, lock.
In addition, shown in enlarged drawing in the circle of Fig. 4, in the present embodiment, between both sides side plate 23, tooth plate 24 becomes by the stacked state in no gap, and also can clamp dividing plate at the not stacked tooth plate 24 of center section at the stacked multi-disc tooth plate 24 of side plate 23 sides.
As mentioned above, the occasion formed locking teeth 22 by stacked multi-disc tooth plate 24 also has following advantage.That is, just carry out stackedly, then can constitute and hook card shape medium 4 easily or easily to blocking the locking teeth 22 that shape medium 4 cause damage if each formed burr in tooth plate 24 edges is not carried out aftertreatment.Usually, burr is unwanted often, but in the card reader of present embodiment, on the contrary, by utilizing this burr, can make the locking teeth 22 that is suitable for carrying out the card locking.And, in the above-mentioned occasion that makes stepped construction like that, have the tooth plate 24 of burr by stacked polylith, make the locking teeth 22 that burr is more and be very easy to hook owing to can constitute, so can expect to make the equipment that carries out the card locking.
Along card conveyance direction and the position parallel with securing rod 20 planes of rotation is provided with conveyance roller 25a, 25b.This conveyance roller 25a, 25b, its part is set as to card conveyance road 8 outstanding, will block shape medium 4 conveyance clampingly between upside conveyance roller 25a and downside conveyance roller 25b.
In addition, the side relative with securing rod 20 in conveyance road 8 is provided with the conveyance platform 26 of the card conveyance face in conveyance road 8 being determined usefulness.After securing rod 20 is driven, between the locking teeth 22 of conveyance platform 26 and securing rod 20, will blocks shape medium 4 and sandwich, and can stop it to move.
And downside conveyance roller 25b is outstanding in card conveyance road 8 from conveyance platform 26, and card shape medium 4 can be by conveyance with the state that floats slightly from conveyance platform 26.Therefore, as mentioned above, after securing rod 20 was driven, when bad behavior person carries out card when extracting, card shape medium 4 moved to the direction of extracting slightly, and locking teeth 22 is bitten card shape medium 4 deeply with the amount of come-up, and locking blocks shape medium 4, prevents to extract.
Then, major part is being amplified among the Fig. 6 that is illustrated in the circle, pushing back of card locking device 10 prevents locking mechanism, on described fixed frame 11, be provided with the slotted hole 11a that extends to back-end framework portion along its length, near described movable framework 12 upper frame rearward end, be provided with the inclined elongate 12a that tilts to length direction.Fixed frame 11 and movable framework 12 are by being connected with the stop pin 30 that inclined elongate 12a is communicated with these each slotted holes 11a.That is, movable framework 12 relative fixed frameworks 11 slide and also move back and forth, and by the reciprocating action of so movable framework 12, just move with the slotted hole 11a of the state relative fixed framework 11 of following stop pin 30 position of inclined elongate 12a.Stop pin 30 is subjected to from the normality position application of force of right-hand card inserting mouth 3 to figure because of being connected with force application spring 31.In addition, locking additional pin 32 is provided with integratedly and is fixed near the rearward end of movable framework 12.The lower surface butt of the length direction of this locking additional pin 32 and fixed frame 11 also is directed, and moves along with moving back and forth of movable framework 12.Therefore, this movable framework 12 rests on the normality position by clamping device 6 under the state that overcomes force application spring 31 elastic force, when when clamping device 6 actions card only being disengaged, can utilize force application spring 31 right-hand forward motion of doing in figure.
In addition, this pushing back prevents that locking mechanism has from latched position described stop pin 30 removed the unlocking lever 33 of usefulness, and have Elastic Contact at the axial spring member 34 of the rotation of this unlocking lever 33.That is, by rotating operation unlocking lever 33, thereby the end 34a of spring member 34 is pressed against on the stop pin 30, the stop pin 30 that becomes lock-out state is moved from latched position, state can unlock.
Among Fig. 2 and Fig. 3, symbol 7 expressions send to switching signal the microswitch of drive source 5 etc., and outside outstanding elastic contact chip 7a can engage, break away from the convex contact site 13a on being located at described conversion rod 13.Promptly, drive source 5 moves according to the detected signal that abends to card shape medium 4, the card of the movable framework 12 of card locking device 10 is only removed and when making it from normality position forward motion, conversion rod 13 rotates, its convex contact site 13a breaks away from elastic contact chip 7a, and microswitch 7 just is switched on or switched off.
The following describes the action of above-mentioned card reader.
When inserting card shape medium 4 from card inserting mouth 3, judge according to the detection signal that monitoring sensor sends whether these card shape medium 4 are regulation cards, and when being judged as the regulation card, protective door is opened, card shape medium 4 can insert in the card reader body 1.Open, block shape medium 4 when inserting when protective door, should block 4 conveyances of shape medium to reading position etc., read and handle or write processing etc. with the conveyance roller to the inboard.
In the work, after client had just inserted card shape medium 4, the fault because of generations such as the internal mechanism of card reader body 1 or electrical systems made card shape medium 4 abend, be detained near card inserting mouth 3 sometimes.In addition, bad behavior person carries out devious conduct sometimes, has a mind to play tricks, and the card shape medium 4 that client inserts under the state that protective door is opened are stopped.Leave on-the-spot space client's callwork personnel that lack common sense etc., probably have this bad behavior person to extract the phenomenon that card shape medium 4 are usurped.
When protective door is in open mode, if monitoring arrangements such as media detection sensor detect the phenomenon that card release shape medium 4 abend, then actuating signal is sent to drive source 5 according to this detection signal, clamping device 6 moves with respect to being ended by card at the movable framework 12 of normality position, removes card and ends.That is, the output shaft of the electromagnet of drive source 5 is drawn in (moving to card inserting mouth 3 sides), and clamping device 6 is that the pin 5a of center on being located at output shaft moves with pin 6b, thereby the holding section 6a of clamping device 6 leaves the holding section 12b of movable framework 12.Be disengaged movable framework 12 that card ends by force application spring 31 effects and advance to card inserting mouth 3, the conversion rod 13 that is connected on movable framework 12 leading sections is rotated, by conversion rod 13, make securing rod 20 make positive rotation around the axial turning anticlockwise direction of fulcrum pin 17.Make the securing rod 20 of positive rotation to the turning anticlockwise direction, make the locking teeth 22 of its bar body 21 and the surperficial butt of the card shape medium 4 that abend.
Should circulate a notice of that card shape medium 4 abend, client leaves on-the-spot occasion, bad behavior person attempts to extract card shape medium 4 and the occasion usurped during this space, extracting of card locking device 10 prevents that locking mechanism from first moving.
Because of bad behavior person's withdrawal force P, rotate around the axial turning anticlockwise direction of fulcrum pin 17 with regard to desire with the securing rod 20 of the surperficial butt of card shape medium 4, and act as the state that locking teeth 22 is bitten card face.The all the more big withdrawal force P that applies of bad behavior person, locking teeth 22 rotates to the locking teeth 22b of the big R2 of the radius of gyration gradually from the locking teeth 22a of radius of gyration R1, along with radius of gyration R shifts to bigger locking teeth 22, the power of biting card shape medium 4 surfaces of this locking teeth 22 just is increased.That is, with one way system, the direction that is acted on to withdrawal force P increases the mobile prevention power (latching force) for card shape medium 4 of securing rod 20, will block 4 lockings of shape medium and remain on the delay position.
In the present embodiment that is formed by the thin plate steel plate, locking teeth 22 is bitten card face, is that the locking teeth of multi-disc tooth plate 24 is bitten card shape medium 4 from the surface, and the side plate 23 that the slab steel plate of both sides forms is with the surface of its all end face pushing card shape medium 4.Because bar body 21 is stepped constructions of side plate 23 and tooth plate 24 so, and be wide cut, therefore, it contacts perhaps multiple spot and the surperficial butt that blocks shape medium 4 with face commodiously to the card Width, can stop it to move reliably and lock, can prevent the improper card shape medium 4 of usurping of bad behavior person.
On the other hand, utilize extracting of this card locking device 20 to prevent the effect of locking mechanism, being judged as bad behavior person only extracts and can not take out card shape medium 4, and following situation is arranged sometimes: attempt will be on the contrary with these card shape medium 4 inwards thruster return, extract repeatedly, push back, continue improper taking-up card shape medium 4 doggedly.In this occasion, the next one of card locking device 20 pushes back and prevents the locking mechanism action.
When bad behavior person will desire when the direction opposite with withdrawal force P will be blocked shape medium 4 and be back in the device side, securing rod 20 with one-way function is done despining because of this pushes back power slightly to clockwise gyratory directions, the latching force absent-mindedness that locking teeth 22 produces, card shape medium 4 card conveyance direction of left in figure moves.But moving of these card shape medium 4 also is limited slightly.That is, bad behavior person's the power that pushes back is given conversion rod 13 from securing rod 20 back transfer, is transformed into the setback of left in figure that overcomes force application spring 31 of movable framework 12 by this conversion rod 13.
When movable framework 12 retreats, the stop pin 30 in the inclined elongate 12a also with its more integratedly in figure left move.This of stop pin 30 moves, by the slotted hole 11a guiding of fixed frame 11.Soon, stop pin 30 is come the cross part of the surface level among the slotted hole 11a of inclined-plane among the inclined elongate 12a of movable framework 12 and fixed frame 11, suppress by being clipped in inclined-plane and the surface level in this cross part and applying, and stop stop pin 30 to move again, make lock-out state.This lock-out state for stop pin 30, the locking additional pin 32 that moves with movable framework 12 is with the lower surface butt of the length direction of fixed frame 11 and be directed, the come-up that stops movable framework 12 because of the generation of inclined-plane power, the result, the come-up of this movable framework 12 stops power also to act on stop pin 30, thus, utilize the three-point support of the bearing surface of the inclined-plane of surface level, inclined elongate 12 of slotted hole 11a and locking additional pin 32, stop pin 30 is carried out brute force lock.
When stop pin 30 is locked; just prevent movable framework 12 to move to pushing back direction; the despining of securing rod 20 stops; latching force to card shape medium 4 does not change, like this, even bad behavior person attempts card shape medium 4 are extracted, pushed back; take out card doggedly; also can stop this behavior, protection card shape medium 4 prevent to usurp.
As mentioned above, extracting of card locking device 10 prevents from locking mechanism and pushes back to prevent that locking mechanism is in action, conveyance platform 26 links with the locking teeth 22 of securing rod 20, sandwich between them by blocking shape medium 4, stop it to move, thereby play the effect of offsetting the power that card that bad behavior person carried out extracts and push back.
In more detail, near securing rod 20, card shape medium 4 are clamped between upside conveyance roller 25a and the downside conveyance roller 25b, can be with the state that floats slightly from conveyance platform 26 by conveyance.Therefore, after securing rod 20 was driven, when bad behavior person carries out card when extracting, card shape medium 4 just moved to the direction of extracting slightly, and locking teeth 22 is bitten card shape medium 4 dearly with the amount of come-up, and locking blocks shape medium 4, prevents to extract.

That is, when final stage gear 35b rotated by drive source 5A, engaging the line space of advancing with pin 36b up to protuberance 36a changeed, and when protuberance 36a engages with pin 36b, the final stage gear 35a that is fixed on the driving shaft 35c is rotated integratedly.
The end side of sector gear 37 is connected with connecting pin 14A on the end of connecting link (conversion rod) 13A, and it is on the securing rod 20A that the other end of this connecting link (conversion rod) 13A is rotatably connected to the alleged locking component of the present invention by connecting pin 15A.
In addition, near sector gear 37, dispose the microswitch 7A that switching signal is delivered to drive source 5A.As shown in Figure 8, the connecting pin 14A that is located at sector gear 37 end side can fasten, break away from the outstanding elastic contact chip 7Aa in the outside of microswitch 7A.Promptly, drive source 5A moves according to the detected signal that abends to card shape medium 4, and the card of removing card locking device 10A ends, and sector gear 37 rotates from the normality position, connecting pin 14A breaks away from elastic contact chip 7Aa, thereby just microswitch 7A is switched on or switched off.
Securing rod 20A extracts the main member that prevents in the locking mechanism, and as Fig. 8 and shown in Figure 9, whole bar body 21A forms the such shape of ratchet.At the central portion of bar body 21A or near the position of leading section, be connected with connecting pin 15A on the other end of connecting link 13A, the base end part of bar body 21A turns the earth's axis and is bearing on the fulcrum pin 17A.Therefore, bar body 21A is subjected to can making positive rotation around the axial turning anticlockwise direction of fulcrum pin 17A from the rotating force of connecting link 13A, and can do despining to clockwise gyratory directions.
Bar body 21A is the stepped construction that is made of multi-disc, have 2 side plate 23A that form with thick slightly steel plate in the both sides of width dimensions direction, and each side plate 23A chien shih thin plate steel plate forms, and the tooth plate 24A of similar shape size of for example 2 formations of roughly the same shape is stacked to be constituted.Specifically, shown in enlarged drawing in the circle among Fig. 7, make 1 tooth plate 24A be connected to the inboard of each side plate 23A, accompany dividing plate between a tooth plate 24A and another tooth plate 24A.And the quantity of tooth plate 24 is not limited to this, as above-mentioned locking teeth 22, also can seamlessly be provided with tooth plate 24.
By with stepped construction bar body 21A being formed wide cut like this, each locking teeth 22A of side plate 23A and tooth plate 24A is just along the surperficial butt of card Width (is vertical direction with respect to the card direction of travel) with wide cut perhaps multiple spot and card shape medium 4, just can stop it to move reliably, be locked.
So, make the occasion of stepped construction in broad ways, these locking teeths 22A's hooks or is inserted in position and zone on the card shape medium 4, just along increasing for vertical card Width with respect to card shape medium 4 direction of travel.Therefore, the what is called that even by force card is carried out drawing when improper taking-up card, also can improve, reinforcement and this behavior contends with is extracted endurance.
In the present embodiment, yes so carries out stackedly, still, also can be not only only stackedly, and can be to be laminated into the state that is mixed with tooth plate 24A and has the side plate 23A of thickness.Carry out under the state that so is mixed with tooth plate 24A and side plate 23A stacked after, can constitute and be hooked in card shape medium 4 lip-deep locking teeth 22A easily, this point is desirable.
Though also can form locking teeth 22A by only stacked this tooth plate 24A, but if consider that the part number is too much, machining clearance too increases and because of the limit etc. of collapsing that undercapacity produced of tooth plate 24A, then by side plate 23 is configured in the Width two ends, can not only guarantee to hook easily, and can obtain the balance of part number and machining clearance, be desirable.
Be formed with locking teeth 22A as fastener at the periphery of side plate 23A and tooth plate 24A leading section, this locking teeth 22A is made of the thrust of a sharp keen claw-like.
In addition, as shown in Figure 9, the periphery of bar body 21A and the front end of locking teeth 22A are roughly the same diameter.That is, the distance till from locking teeth 22A to fulcrum pin 17A forms identical with the radius of gyration R that with fulcrum pin 17A is center of rotation.
The movable range of locking teeth 22A preferably, above-mentioned locking teeth 22A can be turned to the degree of intersecting with the conveyance road 8 that blocks shape medium 4 at least.In this occasion, not only make locking teeth 22A only with the surperficial butt (contact) of card shape medium 4, and the position of a claw-like can be inserted on the card shape medium 4.
In more detail, for example securing rod 20A is identical with the above embodiments, because near the securing rod 20A, card shape medium 4 are clamped between not shown upside conveyance roller and the downside conveyance roller, can be with the state that floats slightly from conveyance platform 26 by conveyance, so can rotate in the scope that locking teeth 22A is enough to be inserted on the card shape medium 4.Therefore, when the improper taking-up of being carried out of card such as extracting, locking teeth 22A is inserted on these card shape medium 4, according to circumstances becomes the state that penetrates card shape medium 4, can improve or strengthen that to stand the power that card shape medium 4 further desire to be pulled out be that what is called is extracted endurance.
In addition, in the present embodiment, be formed at the tooth top of the locking teeth 22A of tooth plate 24A periphery, form size and the shape more outstanding slightly laterally than the locking teeth 22A that is formed at side plate 23A periphery.
As mentioned above, the occasion by stacked polylith tooth plate 24A, formation locking teeth 22A also has following such advantage.That is, just carry out stackedly, can constitute and be hooked in card shape medium 4 or easy locking teeth 22A easily its scuffing if the burr that each tooth plate 24A edge is formed does not carry out aftertreatment.Usually, burr is not wanted often, but in the card reader of present embodiment, on the contrary, by utilizing this burr, can make the locking teeth 22A that is suitable for carrying out the card locking.And, as mentioned above, making the occasion of stepped construction, have the tooth plate 24A of burr by overlapping polylith, just can expect to do to become and can constitute the more and locking teeth 22A that is very easy to hook of burr, the equipment that carries out the card locking of making.
As mentioned above, be formed at each locking teeth 22A of securing rod 20A peripheral part, be configured on the path that the part (information recording part) of the recorded information that is called magnetic strips or IC chip etc. of card shape medium 4 passed through.In the card reader of like this present embodiment of configuration, when carrying out improper taking-up card, the information recording part of these card shape medium 4 can be broken to the degree that can not re-use because of extracting etc.Therefore, promptly use the temporary transient improper card shape medium 4 that taken out of behavior very cleverly, also can avoid these card shape medium 4 by the phenomenon of improper use.
The following describes the action of above-mentioned card locking device.Because the card reader of taking in the card locking device is with above-mentioned identical, thus not shown, describe with same-sign.
Though it is not shown, but when card shape medium 4 when the card inserting mouth 3 of card reader inserts, judge according to the detection signal of monitoring sensor whether these card shape medium 4 are regulation cards, when being judged as the regulation card, protective door (not shown) is opened, and card shape medium 4 can insert in the card reader body 1.Open, will block shape medium 4 again when insert the inboard when protective door, just should block 4 conveyances of shape medium to reading position etc., read processing or write processing etc. with conveyance roller (for example 25a, 25b).
In the work, after client just will block shape medium 4 and insert, because of breaking down, the internal mechanism of card reader body 1 or electrical system make card shape medium 4 abend, be trapped near the card inserting mouth 3 sometimes.Sometimes bad behavior person carries out devious conduct, plays tricks, and the card shape medium 4 of having a mind to client is inserted under the state that protective door is opened stop.The client who probably has this bad behavior person to take advantage of to lack common sense leaves on-the-spot space because of callwork personnel wait, will block shape medium 4 extracts the anxiety of usurping.
When protective door is in open mode, if monitoring arrangements such as media detection sensor detect the phenomenon that card release shape medium 4 abend, then according to this detection signal actuating signal is sent to motor as drive source 5A, drive source (motor) 5A rotates to prescribed direction.This rotation passes to gear set 35.
Here, when final stage gear 35b rotates by drive source 5A, dally, with till pin 36b engages, when protuberance 36a engages with pin 36b, make the final stage gear 35a one rotation that is fixed on the driving shaft 35c up to protuberance 36a.
Like this, final stage gear 35a, the 35b of gear set 35 rotate with being decelerated, and sector gear 37 rotates.By the rotation of sector gear 37, the connecting link 13A that axle is bearing in its side just rotates.Securing rod 20A makes positive rotation by connecting link 13A around the axial turning anticlockwise direction of fulcrum pin 17A.Make the securing rod 20A of positive rotation to the turning anticlockwise direction, the surperficial butt of the locking teeth 22A of its bar body 21A and the card shape medium 4 that abend or bite card shape medium 4.
Should circulate a notice of that card shape medium 4 abend, client leaves on-the-spot such occasion, and takes advantage of this space to attempt to desire to extract the occasion that card shape medium 4 are usurped bad behavior person, extracting of card locking device 10A prevents that locking mechanism from first moving.
With the securing rod 20A of card shape medium 4 surperficial butts, rotate around the axial turning anticlockwise direction of fulcrum pin 17A because of the withdrawal force P desire that bad behavior person carries out, the locking teeth 22A of tooth plate 24A does in order to bite card face.That is, the mobile prevention power (latching force) of card shape medium 4 is increased biting of locking teeth 22A with the one way system of pin-type clutch mechanism 36 to the direction that withdrawal force P works, remain on the delay position thereby will block 4 lockings of shape medium by what make securing rod 20A.
Then, when bad behavior person when pushing back direction pushing card shape medium 4, pin-type clutch mechanism 36 actions of card locking device 10A.
That is, as shown in Figure 8, the card shape medium 4 that locked tooth 22A bites are pushed when getting back in the card reader body 1, and securing rod 20A, connecting link 13A be right-hand moving in figure just, and sector gear 37 is to counterclockwise rotating.Thus, final stage gear 35a and driving shaft 35c begin rotation.Be located at the protuberance 36a that pin 36b on the driving shaft 35c leaves institute's butt and begin freely to rotate, and be separated by 180 ° other protuberance 36a butt.
In this zone that rotates freely, owing to be not activated the load of source (motor) 5A and gear set 35, so securing rod 20A can utilize the power of pushing back to be rotated, 1 pawl that forms locking teeth 22A is further bitten card shape medium 4, can not extract.
Behind pin 36b and the other protuberance 36a butt, the power of pushing back influences and becomes to make drive source 5A or gear set 35 rotations, and to stop torque bigger but they had, so be difficult to card shape medium 4 are further pushed back.
Thus, no matter bad behavior person will block shape medium 4 pushes back or extracts, and can not extract from locking teeth 22A.
