Abstract
Abstract A validator for a card bearing a code readable by moving the card forward past a reader, particularly for use in a vendor to control vending, in which the card is transported forward from an entry position past the reader to an escrow position. If read as valid, the card is maintained in the escrow position pending the user's decision to have the card collected or to obtain return of his card. If the card is read as invalid, it is immediately fed back to the user. The card transport is such as to prevent a valid card from being pulled back out of the validator as by a string or tape attached to the card, and the validator is so constructed that it is easily opened for servicing, including removal of a card which may become jammed in the validator.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
281 words
A validator for a card bearing a code readable by moving the card forward past a reader, comprising: means for guiding a card for travel along a predetermined path, the card being movable forward in said guide means from a position of entry therein; a reader for reading the code on the card as it travels forward along said path from said entry position; card transport means comprising a plurality of pushers of which a first is movable forward from a starting position trailing the card in entry position to a second position to engage the trailing end of the card and push it forward from the entry position to a second position, and a second is movable forward with the first from a starting position leading the card in entry position to a second position and is movable in the reverse direction to push the card back in the guide means for return of the card; and means for driving the card transport means in forward direction for the first pusher to push a card forward in the guide means from its entry position past the reader to read the code on the card and deliver the card to the second position, and for driving the card transport means in the reverse direction for the second pusher to push a card back in the guide means for return of the card, said driving means including means for maintaining the position of the pusher at the trailing end of a card in the second position for preventing the card from being pulled back out of the guide means while allowing the card transport means to be driven in the reverse direction.
Claim 2
Dependent Claim
281 words
A validator for a card bearing a code readable by moving the card forward past a reader, comprising: means for guiding a card for travel along a predetermined path, the card being movable forward in said guide means from a position of entry therein; a reader for reading the code on the card as it travels forward along said path from said entry position; card transport means comprising a plurality of pushers of which a first is movable forward from a starting position trailing the card in entry position to a second position to engage the trailing end of the card and push it forward from the entry position to a second position, and a second is movable forward with the first from a starting position leading the card in entry position to a second position and is movable in the reverse direction to push the card back in the guide means for return of the card; and means for driving the card transport means in forward direction for the first pusher to push a card forward in the guide means from its entry position past the reader to read the code on the card and deliver the card to the second position, and for driving the card transport means in the reverse direction for the second pusher to push a card back in the guide means for return of the card, said driving means including means for maintaining the position of the pusher at the trailing end of a card in the second position for preventing the card from being pulled back out of the guide means while allowing the card transport means to be driven in the reverse direction.
Claim 3
Dependent Claim
80 words
A validator as set forth in claim 1 wherein said second position is an escrow position at which said card dwells until the next operation of the driving means, said driving means being selectively operable to drive the card transport means in a forward direction for collection of a card read as valid and to drive the card transport means in the reverse direction for the second pusher to push a card back in the guide means for return thereof.
Claim 4
Dependent Claim
58 words
A validator as set forth in claim 1 wherein said guide means comprises a base over which a card is slidable, a guide extending along the base engageable by one side of the card as it slides along the base for guiding the card for travel in said path, and means for biasing the card against said guide.
Claim 5
Dependent Claim
21 words
A validator as set forth in claim 3 wherein said biasing means is engageable with the other side of the card.
Claim 6
Dependent Claim
20 words
A validator as set forth in claim 3 having a cover over said base adapted to be opened and closed.
Claim 7
Dependent Claim
28 words
A validator as set forth in claim 5 wherein said reader is mounted in the base and said cover has means for pressing a card against the reader.
Claim 8
Dependent Claim
32 words
A validator as set forth in claim 1 having means responsive to insertion of a card in the guide means for starting said driving means to drive the card transport means forward.
Claim 9
Dependent Claim
32 words
A validator as set forth in claim 1 wherein said drive means comprises a reversible electric motor and a drive which is irreversible from the card transport means back to the motor.
Claim 10
Dependent Claim
60 words
A validator as set forth in claim 1 wherein said card transport means comprises an endless conveyor having a series of said pushers thereon spaced at equal intervals along its length, the spacing being greater than the length of a card, and said drive means is operable through a cycle to index the conveyor forward through one of said intervals.
Claim 11
Dependent Claim
37 words
A validator as set forth in claim 9 wherein the endless conveyor has an at-rest position wherein one pusher of the series constitutes the stated first pusher and the next pusher forward constitutes the stated second pusher.
Claim 12
Dependent Claim

A validator as set forth in claim 10 wherein, with the endless conveyor in its at-rest position, the said first pusher is located clear of said path to enable a card to be inserted endwise into said guide means, said first pusher moving into said path behind the card on operation of said transport means following insertion of the card.
Claim 13
Dependent Claim
44 words
A validator as set forth in claim 11 having means reponsive to insertion of a card in said guide means to a point where said first pusher may move into position behind a card for starting said driving means to drive said conveyor forward.

A validator for a card bearing a code readable by moving the card forward past a reader, comprising: means defining a linear channel adapted for endwise insertion of a card at one end thereof and for endwise movement of the card therethrough; a reader located along said channel for reading a card moving forward in said channel from an entry position into which the card is inserted to a dwell position; at least one endless belt; means guiding the belt for travel in an endless path including a linear reach extending longitudinally of said channel, said belt having a series of pushers spaced at equal intervals along its length and extending outwardly from the belt, the spacing of the pushers being greater than the length of a card; and means comprising a reversible electric motor for driving the belt in a forward direction for a first one of said pushers to move the card forward along the channel from its entry position past the reader and deliver the card to the dwell position and for driving the belt in the reverse direction for a second one of said pushers to move the card back in the channel for return of the card, said driving means further comprising means for maintaining the position of the first said pusher for preventing the card from being pulled back out of the guide means while allowing the belt to be driven in the reverse direction.
Claim 16
