Abstract
Abstract Card comparing apparatus for mechanically comparing an embossed card comprising a slidable carriage having a seat for receiving a pair of cards in front to back face relationship, said cards having embossed printing thereon, and a mechanical mechanism for detecting any difference in the embossed printing. One detecting mechanism senses the difference in the combined thickness of matched cards and mismatched cards, and includes a pair of rollers spaced apart a distance sufficient to pass a pair of matched cards and to block passage of a pair of mismatched cards. Another detecting mechanism includes a pair of rollers for sliding mismatched cards in opposite directions. The embossed printing on the cards is from a printing font having printing elements which nest only with identical elements in the font and do not nest with any other elements. The embossed printing elements have rounded raised portions permitting closer nesting than embossed printing having raised portions with flat tops and side portions angled away therefrom.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
126 words
In a system for comparing the identity or non-identity of plural cards having raised characters embossed thereon in a similar predetermined area on the face of the cards, card comparing apparatus comprising means for supporting two such cards in front to back nested relationship, mechanical means adjacent to said supporting means adapted to grip the nested cards to feed the same therepast, and detecting means on said mechanical means to co-act with said raised characters permitting passage of said nested cards therepast when the raised characters are in complete matching relationship for the entire extent thereof, said detecting means preventing passage of said cards therepast when at least one of said characters on one card is mismatched with the corresponding positioned character on the other card.
Claim 2
Dependent Claim
126 words
In a system for comparing the identity or non-identity of plural cards having raised characters embossed thereon in a similar predetermined area on the face of the cards, card comparing apparatus comprising means for supporting two such cards in front to back nested relationship, mechanical means adjacent to said supporting means adapted to grip the nested cards to feed the same therepast, and detecting means on said mechanical means to co-act with said raised characters permitting passage of said nested cards therepast when the raised characters are in complete matching relationship for the entire extent thereof, said detecting means preventing passage of said cards therepast when at least one of said characters on one card is mismatched with the corresponding positioned character on the other card.
Claim 3
Dependent Claim
28 words
The card comparing apparatus of claim 1 wherein said mechanical detecting means comprises means for sensing the difference in the combined thickness of matched cards and mismatched cards.
Claim 4
Dependent Claim
21 words
The card comparing apparatus of claim 1 wherein said mechanical detecting means comprises means for sliding mismatched cards in opposite directions.
Claim 5
Dependent Claim
56 words
The card comparing apparatus of claim 1 including a first card with printing embossed thereon, and a second card with printing embossed thereon, said embossed printing including printing elements from a printing font having printing elements which nest only with identical elements in the font and do not nest with any other elements of the font.
Claim 6
Dependent Claim
32 words
The card comparing apparatus of claim 1, said embossed printing having rounded raised portions permitting closer nesting than embossed printing having raised portions with flat tops and side portions angled away therefrom.
Claim 7
Dependent Claim
32 words
The card comparing apparatus of claim 4, said embossed printing having rounded raised portions permittinG closer nesting than embossed printing having raised portions with flat tops and side portions angled away therefrom.
Claim 8
Dependent Claim
23 words
The card comparing apparatus of claim 1, said card receiving means including a carriage having a seat for receiving said pair of cards.
Claim 9
Dependent Claim
38 words
The card comparing apparatus of claim 1, said mechanical detecting means including a pair of rollers spaced apart a distance sufficient to pass a pair of matched cards and to block passage of a pair of mismatched cards.
Claim 10
Dependent Claim
37 words
The card comparing apparatus of claim 1, including means for printing the embossed printing of matched cards on a sheet of paper to provide a permanent record of the matching and the information of the embossed print.
Claim 11
Dependent Claim
21 words
The card comparing apparatus of claim 1, including means for signalling that the cards have been compared and found to match.
Claim 12
Dependent Claim
64 words
The card comparing apparatus of claim 1, said mechanical detecting means including a pair of rollers mounted on shafts, and gear means connecting the shafts together so that they rotate at different speeds causing one roller to exert a force on a card opposite to the force exerted by the other roller on the other card, whereby mismatched cards are separated by the rollers.
