Abstract
Abstract The apparatus comprises a card positioning member for correctly positioning a magnetic card in its movement along its path of travel adjustable in its position relative to the path of travel of the card. By adjusting the position of the card positioning member in accordance with the size and type of the magnetic card to be handled, it is possible to bring the magnetic tracks on the card into alignment with the magnetic head and cause the magnetic tracks to be correctly oriented relative to the magnetic gap of the magnetic head when the card moves along its path of travel while being maintained in pressing engagement with the card positioning member, whereby information can be magnetically recorded on the card or the information carried by the card can be magnetically read.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
221 words
A magnetic card reader-recorder comprising an upper frame and a lower frame defining a path of movement of a magnetic card therebetween, card moving means for moving the magnetic card along said path of movement while deflecting the card to one side of the path, a magnetic head fixed to one of said upper frame and said lower frame and adapted either to magnetically read the information carried by the magnetic card or to magnetically record information on the magnetic card, a card positioning member mounted on said one frame to which said magnetic head is secured and disposed on that edge of said one frame to which the magnetic card is deflected during its movement along its path of movement for accurately positioning the magnetic card on its path of movement, and a pair of longitudinally spaced adjusting means engaged between said card positioning member and said one frame for adjusting said card positioning member relative to said one frame; one adjusting means being located laterally adjacent said magnetic head for setting the lateral location of the card relative to said magnetic head, for tracking adjustment of a card, and the other adjusting means being spaced longitudinally from said magnetic head for setting the angular orientation of a card relative to said magnetic head, for skew correction of a card.
Claim 2
Dependent Claim
221 words
A magnetic card reader-recorder comprising an upper frame and a lower frame defining a path of movement of a magnetic card therebetween, card moving means for moving the magnetic card along said path of movement while deflecting the card to one side of the path, a magnetic head fixed to one of said upper frame and said lower frame and adapted either to magnetically read the information carried by the magnetic card or to magnetically record information on the magnetic card, a card positioning member mounted on said one frame to which said magnetic head is secured and disposed on that edge of said one frame to which the magnetic card is deflected during its movement along its path of movement for accurately positioning the magnetic card on its path of movement, and a pair of longitudinally spaced adjusting means engaged between said card positioning member and said one frame for adjusting said card positioning member relative to said one frame; one adjusting means being located laterally adjacent said magnetic head for setting the lateral location of the card relative to said magnetic head, for tracking adjustment of a card, and the other adjusting means being spaced longitudinally from said magnetic head for setting the angular orientation of a card relative to said magnetic head, for skew correction of a card.
Claim 3
Dependent Claim
48 words
A magnetic card reader-recorder as set forth in claim 1 wherein said card moving means comprises a frusto-conical roller made of a soft material and arranged such that its major diameter peripheral edge faces the edge of said one frame on which said card positioning member is disposed.
Claim 4
Dependent Claim
48 words
A magnetic card rEader-recorder as set forth in claim 1 wherein said card moving means comprises a frusto-conical roller made of a hard material and arranged such that its minor diameter peripheral edge faces the edge of said one frame on which said card positioning member is disposed.
Claim 5
Dependent Claim
19 words
A magnetic card reader-recorder as set forth in claim 1 wherein said card positioning member is an elongated plate.
Claim 6
Dependent Claim
22 words
A magnetic card reader-recorder as set forth in claim 1 wherein said card positioning member is an elongated plate of L-shaped cross-section.
Claim 7
Dependent Claim
18 words
A magnetic card reader-recorder as set forth in claim 1 wherein said card positioning member is a bar.
Claim 8
Dependent Claim
56 words
A magnetic card reader-recorder as set forth in claim 1 wherein said card positioning member adjusting means comprises adjusting screws for correctly positioning the card positioning member with respect to said one frame on which the magnetic head is mounted, and guides for holding in position the card positioning member after the latter is correctly positioned.
Claim 9
Dependent Claim
109 words
A magnetic card reader-recorder as set forth in claim 4 wherein said plate is held in position at one side of the path of movement of the magnetic card by card positioning member adjusting means comprising adjusting screws threaded into two portions of the plate and each having a front end positioned against the frame to which the magnetic head is fixed, guides connected to two portions of the plate and threaded into the frame to which the magnetic head is secured, and at least one spring adapted to urge the front ends of said adjusting screws into engagement with the frame to which the magnetic head is secured.
Claim 10
Dependent Claim
111 words
A magnetic card reader-recorder as set forth in claim 5 wherein said plate is held in position at one side of the path of movement of the magnetic card by card positioning member adjusting means comprising adjusting screws threadably connected to two portions of the vertical member of the plate and loosely inserted in the frame to which the magnetic head is secured, fixing screws loosely inserted in the frame to which the magnetic head is secured and threadably connected to two portions of the horizontal member of the plate, and at least one spring adapted to bias the plate relative to the frame to which the magnetic head is secured.
Claim 11
Dependent Claim
127 words
A magnetic card reader-recorder as set forth in claim 5 wherein the plate is held in position at one side of the path of movement of the magnetic card by card positioning member adjusting means comprising guide members threadably connected to two portions of the vertical member of the plate and loosely inserted in the frame to which the magnetic head is secured, adjusting screws threadably connected to the frame to which the magnetic head is secured and each having a conical front end portion, said conical front end portions of said adjusting screws being maintained in engagement with two portions of the horizontal member of the plate, and at least one spring adapted to bias the plate relative to said adjusting screws by its biasing force.
Claim 12
Dependent Claim
108 words
A magnetic card reader-recorder as set forth in claim 6 wherein said bar is held in position at one side of the path of movement of the magnetic card by card positioning member adjusting means comprising a pair of arms supporting the block and mounted on a base for sliding motion toward or away from the frame to which the magnetic head is secured, adjusting screws threadably connected to two portions of the base and adapted to adjust the bar relative to the path of movement of the magnetic card, and at least one spring adapted to bias the bar to engage said arms with said adjusting screws.
