Definitions

  • ABSTRACT The invention relates to apparatus for processing cardcarried data, and the object of the invention is to reduce the possibility of an unauthorised card being fed into such apparatus. For this purpose a passage leading from a card entry slot to the data processing means is blocked unless a card of a predetermined minimum width is present in the slot.
  • the passage is normally blocked by a pivotably-mounted tray having a forward edge opposite the card entry slot and being held in this blocking position by two spring members mounted one on either side of the tray.
  • card is used herein to denote any convenient form of token, or the like, which may be carried and inserted in data processing apparatus. Such cards may be used, for example, as requisitioning elements for cash or goods dispensing machines, or as stores or programmes for computers.
  • the data, or some of the data, on the card may be represented by the resonant ratus for processing data in or on a card, including a card entry slot, blocking means movable from a first position in which it blocks a passageleading from said slot to data processing means to a second position in which said passage is unblocked, spring means urging said blocking means towards said first position, locking means for retaining said blocking means in said first position and release means operativeto unlock said locking means when a card of a predetermined minimum width enters said slot.
  • the width of the card entry slot is only slightly greater than said predetermined minimum width so that it defines a predetermined maximum width for the card which does not differ substantially from the predetermined minimum width. Accordingly,
  • the blocking means are constituted by a pivotally mounted tray having a forward edge disposed opposite to said card entry slot and urged by spring means in such a direction that said forward edge normally prevents the entry of a card into the apparatus.
  • Said tray is provided with two laterally'projecting pegs capable of entering respective holes in two spring members mounted one on either side of the tray and biassed towards each other so that the pegs are normally engaged in the slots.
  • Each spring member carries at the H forward end thereof a roller. capable of being engaged by a respective lateral edge of a card as it is inserted through said slot.
  • rollers and spring members are arranged and located so that, if a card of the predetermined minimum width is inserted through the. slot, it will engage both rollers and urge them apart so that the pegs projecting laterally from thetray are disengaged from the holes in the spring members. As a result, they tray is unlocked and capable of being displaced from the first position in which it blocks entry to the apparatus. To enable it to be moved to the second or unblocking position, it is provided with ramps on the forward edge thereof, which ramps can. be engaged by the leading edge of the card. As the card is pressed against the companying diagrammatic drawing, taken singly or in combination.
  • the apparatus illustrated includes a card entry slot A, the height of which is such as to prevent entry of objects thicker than the maximumpermitted card thickness. Similarly, the width of the slot is such as to prevent the entry of cards or other objects of a width greater than a predetermined maximum.
  • Two rollers G are carried at the forward ends of respective arms H, one located on each side of the slot.
  • a tracy C pivoted at D and urged in a clockwise direction by the spring arm F of a microswitch E, normally acts as a barrier to prevent the entry of a card or other object.
  • the tray C is provided with two pins K projecting laterally therefrom and passing through holes I in the springs l-l.
  • the card will be able to travel along the upper surface of the tray and will pass below a roller M.
  • the roller M is fixed in the apparatus and, accordingly, the thickness of the card will maintain the tray C in the anticlockwise position.
  • the card can be fed further into the apparatus through the slot A and eventually the leading edge will reach the gap between two rollers N and O, the height of this gap being somewhat less than the thickness of the card.
  • Means are provided to rotate two rollers P and Q in opposite directions, as indicated by the arrows. These two rollers are mounted in a frame comprising two yokes AB which are pivotally mounted on two coaxial pins AA.
  • the frame also includes a mild steel armature AC located between two electromagnets AD and AE.
  • the magnet AB is energised so that the frame is rotated in a clockwise direction, as seen in the drawing, and the roller P is then in contact with the roller 0.
  • the electromagnet AB is de-energised and the electromagnet AD is energised.
  • the frame is rotated in an anticlockwise direction so that the roller Q comes into contact with the roller 0 in place of the roller P.
  • the roller 0 rotates in a clockwise direction and, when the card enters the nip of the rollers N and 0, it is carried between the rollers and advanced on to a spring-loaded slide (not shown) carried on a platen AF.
  • the microswitch E in addition to controlling the electromagnets AE and AD, also controls an electronic timer which, after a predetermined delay, causes energisation of an electromagnet AG.
  • the delay is suffi- AG is energised, the armature moves in the direction.
  • a rod AH coupled thereto moves in the opposite direction.
  • This rod is connected through a spring AM to a pivotallymounted lever AK.
  • This lever is normally biassed in an anticlockwise direction by a spring AL, but is moved in a clockwise direction against the action of this spring by the movement of the rod AH. Accordingly, the
  • the rod AH is provided with a slot through which a pivot pin AJ passes. Pivotally mounted on this pin are two levers AT and AU.
  • the lever AT is pivoted to the frame of the apparatus at AOand the lever AU is pivoted to the platen AF at AP.
  • the movement of the rod AH commences, it has no effect on the levers AT and AU because the pin AJ slides in the slot in the rod.
  • the pin reaches the end of the slot further movement of the rod AH causes the pivot A] to move to the right in the drawing so that the linkage AT/AU tends to assume a straight line position.
  • the platen AF is moved upwardly away from the pivot AD. This action raises the card until it is pressed against the card reading and/or writing means (not shown).
  • the platen AF is provided with two slots, one at each side of its forward end, and two fixed pins AR engage apparatus and the card are arranged so that, at this time, it is possible to retrieve the card manually from the slot A.
  • the tray C again rotates in a clockwise direction under the influence of the spring arm F and the springs H move together to lock the tray in the blocking position, closing ofl the slot A against entry of any object other than a correct sized card.
  • the switching arrangements in the apparatus are arranged so that, when the electromagnet AG is energised, the electromagnet AD cannot be energised by the entry of a further card. Accordingly, if a further correct sized card is inserted while there is already a card on g the platen AF, it will not be gripped by the rollers N and 0. Further, when the first card is ejected at the end of the reading or writing procedure, it will force the second card out from the slot A before emerging itself.
  • blocking means constituted data processing means to a second position in which in respective ones of these slots. Consequently, longitudinal movement of the platen AF is prevented, but the platen is able to rise to force the card against the card reader or writer. It is to be understood that the spring AM stretches to allow the second part of the action of the electromagnet AG while the lever AK holds the card against the shoulder AM.
  • the magnet A is de-energised and the magnet AE is energised.
  • the frame holding the two rollers P and Q is rotated in a clockwise direction and the roller P is brought into contact with the roller 0 in place of the roller 0. Consequently, the direction of rotation of the roller 0 is reversed.
  • the electromagnet AG is de-energised allowing the platen AP to drop and the lever AK to rotate in an anticlockwise direction.
  • the sprung slide in the platen is allowed to move the card to the left in the drawing with the result that the rear edge is engaged by the rollers N and O which are now rotating in the direction necessary to move the card to the left.
  • the card is drawn outwardly, it passes between two rollers AQ carried'respectively by the two springs l-l. These two rollers serve to move the two springs H apart, once again disengaging the pegs K from the holes J in the respective springs.
  • the tray C is unlocked, and is moved in an anticlockwise direction when the card passes between the tray and the roller M. Accordingly, the rollers N and O can continue to drive the card outwardly through the slot A, and the dimensions of the said passage is unblocked, spring means urging said blocking means towards said first position, locking means for retaining said blocking means in said first position and release means operative to unlock said locking means when a card of a predetermined minimum width enters said slot.
  • each spring member carries at the forward end thereof a roller capable of being engaged by a respective lateral edge of a card as it is inserted through said slot.
  • rollers and spring members are so arranged and located that, if a card of said predetermined minimum width is inserted through said slot, it will engage both rollers and urge them apart so that the pegs projecting laterally from the tray are disengaged from the holes in the spring members, wherebythe tray is unlocked and rendered capable of being displaced from said first position in which it blocks entry to the apparatus.
