Definitions

  • ABSTRACT A transport for paper objects has upper and lower platens which coact to define a passageway; and a blocking member is disposed adjacent the entrance of that passageway. Fingers on that blocking member normally are held out of that passageway, but those fingers can be moved into position within that passageway to block that passageway.
  • the blocking member is mounted on a pivot which is closely adjacent to one of the platens, so forces which are applied to the fingers of that blocking member will have small moment arms, and hence could not easily cause those blocking fingers to move very far. Toothed members are disposed adjacent the exit of the passageway; and
  • the teeth on those toothed members are oriented so they can readily permit paper objects to exit from that passageway, but can strongly resist efforts to pull a paper object in the reverse direction between those toothed members.
  • One of the toothed members extends downwardly from the upper platen into the passageway, and the other of those toothed members extends upwardly from the lower platen up into that passageway.
  • the toothed surfaces. on the toothed members are not in register with each other and, instead, are spaced laterally from each other; and the leading edge of at least one of those toothed members acts as an inclined plane to cause inserted paper objects to bow slightly as those paper objects move between those toothed members.
  • Transports for paper objects frequently are equipped with devices and mechanisms that are intended to prevent unauthorized retrieval of paper objects from those transports.
  • those devices or mechanisms must respond to unauthorized efforts to retrieve a paper object to move into position to block such efforts.
  • inertia, dust, lack of lubrication, and the like can retard the rate at which such devices or mechanisms move, it would be desirable to provide devices or mechanisms which were static but which could prevent unauthorized retrieval of paper objects from a transport.
  • the present invention provides a static device which can prevent unauthorized retrieval of a paper object from a transport.
  • that transport has a blocking member adjacent the entrance thereof which has fingers that normally are disposed outwardly of the passageway but which can extend into and through that passageway to block that passageway.
  • the transport provided by the present invention has platens which define a passageway for paper objects; and a blocking member is mounted adjacent the entrance of that passageway. That blocking member has fingers which normally are wholly external of that passageway but which can be selectively moved into that passageway to block unauthorized retrieval of a paper object. Slots are provided in the platens to accommodate the fingers of the blocking member, and those fingers are narrow in a direction which is transverse of the long axis of the passageway, and those slots have rounded ends. Consequently, those slots do not impede movement of paper objects inwardly or outwardly of that passageway.
  • an object of the present invention to provide a transport with upper and lower platens which have rounded-end slots therein that are narrow in a direction which is transverse of the passageway defined by those platens and which accommodate the fingers of a blocking member.
  • the blocking member provided by the present invention is mounted on a pivot which is closely adjacent to one of those platens, and hence is close to that passageway.
  • the disposition of that pivot closely adjacent to the passageway minimizes the rotative moments which forces, that are applied to the fingers of that blocking member, can develop for that blocking member.
  • forces which are applied to the fingers of that blocking member during unauthorized efforts to retrieve the paper objects will develop only small rotative moments. It is, therefore, an object of the present invcntion to mount a blocking member on a pivot which is closely adjacent to a passageway for paper objects.
  • the passageway of the transport of the present invention has toothed members adjacent the exit thereof; and those toothed members are formed so they permit essentially unimpeded movement of paper objects toward and out of the exit of that passageway but strongly resist unauthorized efforts to move those paper objects in the reverse direction.
  • the toothed surfaces on the toothed members are not in register with each other and, instead, are displaced laterally from each other; and hence a paper object can bow as it passes between those toothed surfaces. After that paper object has moved beyond the toothed members,
  • an object of the present invention to provide toothed members, which are located adjacent the exit of the passageway in a transport for paper objects, with toothed surfaces that are displaced laterally from each other to permit paper objects to bow-as they move between those toothed members.
  • One of the toothed members provided by the present invention can be set in a position wherein it is wholly displaced from the passageway and hence is ineffective, or can be set so the teeth thereon extend into the passageway and will effectively prevent retrieval of paper objects in intact form.
  • that movable toothed member will be moved wholly out of the passageway to facilitate unimpeded movement of wrinkled and torn paper objects toward and through the exit of that passageway.
  • that movable toothed member will be moved into the passageway to prevent the withdrawal of paper objects in intact form.

  • the solenoid 388 will be energized, and it will be holding the blocking member 178 in the raised position shown by FIG. 9. If a person were to permit that piece of scrip to move wholly inwardly beyond the slots 171 and 172 in the lower platen 40 and then, after the solenoid 383 had become de-energized and had permitted the spring 393 to move the blocking member 178 downwardly into blocking position, were to attempt to use a ribbon, tape or other tail which he had attached to that piece of scrip to pull that piece of scrip outwardly of the scrip transport 30, the blocking fingers 180 and 181 would be lying directly in the path of that piece of scrip.
  • the present invention disposes the fingers 180 and 181 just a short distance inwardly of the upwardly-inclined trailing edge 38 of the platform 32, that upwardlyinclined trailing edge would coact with the semi-cylindrical leading edge 26 of the upper platen 118 to force the inner end of any thin flexible object to bend upwardly and engage those fingers adjacent to the points where those fingers extend downwardly through the slots 168 and 166.
  • This is important; because it means that the inner end of that thin flexible object would quickly move upwardly into engagement with the lower surface of the platen 118 if that thin flexible object was able to rotate the blocking member 178 in the counterclockwise direction in FIGS. 3 and 4 and such engagement would block further counterclockwise rotation of that blocking member.
  • the lower portions of the leading edges of the fingers 180 and 181 incline forwardly and downwardly from the vertical at a substantial angle. That inclination is important; because it disposes the lower ends of those fingers closer to the pivot 176 than are any portions of those fingers to which a thin flexible object could apply forces. Consequently, even if a person were able to use a thin flexible object to apply forces to 10 the fingers 180 and 181 which tended to rotate the blocking member 178 toward the position of FIG. 9, the lower ends of those fingers would jarn against that thin flexible object and block any such rotation.
  • the apex of at least one tooth on each of the toothed surfaces of the toothed member 218 should be disposed above the level of the apex on the lowermost tooth on the toothed member 216. To attain that result, it would only be necessary to rotate the bolt 223 so it would shift the cam 227 to the position shown by FIG.
  • one of the teeth on the toothed member 216 and at least two of the teeth on the tooth member 218 would intercept the rear edge of that piece of scrip and thereby prevent movement of that piece of scrip back into that passageway.
  • the anti-retrieval effect which is provided by the toothed members 216 and 218 will normally be great enough to cause a person to give up in his attempt to retrieve the piece of scrip. Further, that anti-retrieval effect could cause the ribbon, tape or other tail to break or to pull away from the piece of scrip. However, if a strong ribbon, tape or other tail was used, and if that ribbon, tape or other tail was fixedly secured to the piece of scrip, and if the person was able to pull that ribbon, tape or other tail wholly outwardly of the scrip transport 30, the toothed members 216 and 218 would tear or shred the piece of scrip and keep it from leaving the scrip transport in intact form.
  • toothed sides of the toothed member 218 are generally aligned with the actuators 148 and 158. This is desirable; because if a person were to attach a ribbon, tape or other tail to a piece of scrip in the expectation that the said ribbon, tape or other tail would overlie the toothed sides of the toothed member 218, that ribbon, tape or other tail would keep those actuators from returning to their normal positions with consequent reversal of the motor 562.
  • the trailing edge of the actuator 164 for the switch 162 is close to the toothed member 218. This is desirable; because it means that any piece of scrip which is moved wholly inwardly beyond the actuator 164 will be moved beyond the leading teeth on the toothed sides of the toothed member 218. If a person attempts to retrieve that piece of scrip, those teeth will strongly resist such attempts.
  • a validator which comprises passageway-defining members that are spaced apart to define an elongated shallow passageway for a document, a pivot, a blocking member which is rotatably mounted on said pivot and which has a portion thereof that is selectively disposable in blocking position in said passageway or out of said blocking position, said portion of said blocking member having a leading edge which inclines downwardly and forwardly relative to said passageway, and wherein any point on said leading edge of said portion of said blocking member which can be engaged by an object inserted into said passageway will be further away from said pivot than is the lower part of said leading edge of said portion of said blocking member, whereby said lower part of said leading edge of said portion of said blocking member will jam against said object if said portion of said blocking member tends to rotate out of blocking position in response to the insertion of said object, whereby said leading edge of said portion of said blocking member can keep said object from rotating said portion of said blocking member out of said blocking position.
  • a validator which comprises a sensor, means to provide relative movement between a document and said sensor, a toothed member past which said means will move an accepted document, a further toothed member past which said means will move said accepted document, both of said toothed members being stationary during the acceptance of each acceptable document, said toothed members being near each other but being out of register with each other, whereby said toothed members can require said document to bow transversely as it moves, and to enable it to move, between said toothed members, said document, after it has been moved past said toothed members, responding to the restorative forces therein to reassume its flat condition, at least one of said toothed members lying in the path of reverse movement of said document after said document has reassumed its flat condition, at least one of said toothed members being adjustable at a time when a document is not present in said validator, said one of said toothed members being adjustable to move 1 a toothed surface thereon relative to a toothed surface on the other of said toothe
