Abstract
Abstract A reversing board 14 with a magnetic head 16 mounted thereon is provided at its central portion with card guides 14b1, 14b2 , the inlet ports of the card guides 14b1, 14b2 being disposed proximate to the front end openings of front and rear card guides 2A, 2B, the magnetic head 16 being biased by a compression spring 17S so that the head can be acted upwardly and downwardly, a positioning stopper 15 being engaged in a positioning groove 14a of the reversing board 14, a rotational tension force being exerted to a head reversing gear 12 by a tension spring 13S.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A magnetic card reader comprising a frame having two sides to define a magnetic card passageway through which a magnetic card having a magnetic stripe along an edge thereof may pass through, two magnetic sensors mounted on said frame on an upper side of said passage way and two magnetic sensors mounted on said frame on a lower side of said passageway to determine the position of the magnetic stripe on said magnetic card passing through, reversing boards rotatably mounted on said frame each carrying a magnetic head which to correctly read and write magnetic information from said magnetic stripe of said magnetic card must coincide with said magnetic stripe, means to rotate said reversing board to render said magnetic head coincident with said magnetic stripe and a positioning stopper mounted on said frame wherein each said reversing board is in the form of a disc having two grooves on the periphery thereof diametrically opposed to each other into which said positioning stopper seats to position the magnetic head with respect to the magnetic stripe of said magnetic card.
Claim 2
Dependent Claim
179 words
A magnetic card reader comprising a frame having two sides to define a magnetic card passageway through which a magnetic card having a magnetic stripe along an edge thereof may pass through, two magnetic sensors mounted on said frame on an upper side of said passage way and two magnetic sensors mounted on said frame on a lower side of said passageway to determine the position of the magnetic stripe on said magnetic card passing through, reversing boards rotatably mounted on said frame each carrying a magnetic head which to correctly read and write magnetic information from said magnetic stripe of said magnetic card must coincide with said magnetic stripe, means to rotate said reversing board to render said magnetic head coincident with said magnetic stripe and a positioning stopper mounted on said frame wherein each said reversing board is in the form of a disc having two grooves on the periphery thereof diametrically opposed to each other into which said positioning stopper seats to position the magnetic head with respect to the magnetic stripe of said magnetic card.
Claim 3
Dependent Claim
41 words
The magnetic card reader of claim 1 including a tension spring adapted to exert a controlled amount of unidirectional force to said means for rotating each said reversing board so as to prevent said positioning stopper from disengaging with said groove.
Claim 4
Dependent Claim
15 words
The magnetic card reader of claim 1 wherein said positioning stopper is a plate spring.
Claim 5
Dependent Claim
172 words
A magnetic card reader comprising a frame having two sides to define a magnetic card passageway through which a magnetic card having a magnetic stripe along an edge thereof may pass through, two magnetic sensors mounted on said frame on an upper side of said passage way and two magnetic sensors mounted on said frame on a lower side of said passageway to determine the position of the magnetic stripe on said magnetic card passing through, reversing boards rotatably mounted on said frame each carrying a magnetic head which to correctly read and write magnetic information from said magnetic stripe of said magnetic card must coincide with said magnetic stripe and means to rotate said reversing board to render said magnetic head coincident with said magnetic stripe and each of said reversing boards carrying in addition to said magnetic head a card guide and a head receiving roller on the same side of the board, said card guide positioned to receive said magnetic card passing between said magnetic head and said roller.
Claim 6
Dependent Claim
172 words
A magnetic card reader comprising a frame having two sides to define a magnetic card passageway through which a magnetic card having a magnetic stripe along an edge thereof may pass through, two magnetic sensors mounted on said frame on an upper side of said passage way and two magnetic sensors mounted on said frame on a lower side of said passageway to determine the position of the magnetic stripe on said magnetic card passing through, reversing boards rotatably mounted on said frame each carrying a magnetic head which to correctly read and write magnetic information from said magnetic stripe of said magnetic card must coincide with said magnetic stripe and means to rotate said reversing board to render said magnetic head coincident with said magnetic stripe and each of said reversing boards carrying in addition to said magnetic head a card guide and a head receiving roller on the same side of the board, said card guide positioned to receive said magnetic card passing between said magnetic head and said roller.
Claim 7
Dependent Claim
25 words
The magnetic card reader of claim 4 including biasing means on each of said reversing boards to bias said magnetic head toward said head roller.
