Abstract
Abstract A card conveyance mechanism used in a card reader so as to convey a card in a card travel path. The mechanism includes an abnormal card travel detecting device for detecting whether the card has jammed, and a card discharge device for discharging the card from the travel path in response to an output from the abnormal card travel detecting device. The discharge device includes an endless belt or chain (7) having a projecting pawl (8) which may normally be kept outside the card travel path by position detection sensor (9). The card may be discharged either to the card insertion port (4) or to a recovering box (5).

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
195 words
A card conveyance mechanism used in a card reader so as to convey a card in a card travel path, said mechanism comprising: card conveying means for conveying said card in said card travel path; abnormal card travel detecting means for detecting a normal or abnormal condition of travel of said card and for producing an output signal when the abnormal condition of travel is detected; and card discharge means, which is separate and distinct from said card conveying means, for discharging said card disposed in said card travel path from said card travel path in response to the output signal of said abnormal card travel detecting means, said card discharge means including an endless belt provided along said card travel path, a projection fixedly mounted on said endless belt so as to engage an edge of said card, and drive means for driving said endless belt, wherein said card discharge means is operative independently from said card conveying means and only for discharging said card in response to the output signal, and further wherein said projection, which is mounted on said endless belt, is normally kept at a position outside said card travel path.
Claim 2
Dependent Claim
195 words
A card conveyance mechanism used in a card reader so as to convey a card in a card travel path, said mechanism comprising: card conveying means for conveying said card in said card travel path; abnormal card travel detecting means for detecting a normal or abnormal condition of travel of said card and for producing an output signal when the abnormal condition of travel is detected; and card discharge means, which is separate and distinct from said card conveying means, for discharging said card disposed in said card travel path from said card travel path in response to the output signal of said abnormal card travel detecting means, said card discharge means including an endless belt provided along said card travel path, a projection fixedly mounted on said endless belt so as to engage an edge of said card, and drive means for driving said endless belt, wherein said card discharge means is operative independently from said card conveying means and only for discharging said card in response to the output signal, and further wherein said projection, which is mounted on said endless belt, is normally kept at a position outside said card travel path.
Claim 3
Dependent Claim
55 words
