Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
In reading or recording equipment for cards with a magnetic data carrier, the card being provided with at least one magnetic track, in which the card is inserted into the equipment and held fast and is read or recorded on by a magnetic head disposed within a movable carriage, the carriage adapted for movement over the magnetic track, the improvement comprising: (a) a slot into which said card is inserted for reading; (b) a linearly movable reading gap cover covering said slot and thereby protecting the magnetic head when said equipment is not in use, said reading gap cover adapted to be engaged by the edge of a card which is pushed into said slot; and (c) a stop means for engaging a portion of said reading gap cover as it is pushed in and moves linearly as a card is pushed in, said stop and reading gap cover cooperating so as to establish a positioning of the magnetic data carrier on said card which is in alignment with said magnetic head.
Claim 2
Dependent Claim
172 words

Claim 3
Dependent Claim
31 words
Apparatus according to claim 1 and further including a hold down device responsive to insertion of a card into said equipment for holding said card in place during reading or recording.
Claim 4
Dependent Claim
57 words
Apparatus according to claim 2 and further including means responsive to said recording gap cover being pushed to a predetermined position corresponding to a position where said magnetic track is aligned with said magnetic head and thereupon providing an output and wherein said hold down device is responsive to said output to hold said card in place.
