Abstract

Claims (13)

1. A magnetic stripe card reader comprising:

a magnetic stripe reader head support base having an aperture communicating with a card swipe slot;

a magnetic stripe reader head;

a magnetic stripe reader head bracket supporting said magnetic stripe reader head at least partially in said aperture; and

a pair of coil springs associated with said magnetic stripe reader head bracket and said magnetic stripe reader head support base and arranged such that resilient axial retraction of said magnetic stripe reader head in said aperture is permitted with respect to said card swipe slot,

said magnetic stripe reader head bracket being formed with a pair of mutually spaced mounting apertures; and

a pair of elongate fasteners extend respectively through said pair of coil springs and through said pair of mutually spaced mounting apertures into fixed engagement with said magnetic stripe reader head support base.

2. A magnetic stripe card reader according to claim 1 and wherein each of said pair of elongate fasteners is formed with a shoulder which limits an extent that said fasteners extend beyond said magnetic stripe reader head support base.

3. A magnetic stripe card reader according to claim 1 and wherein each of said pair of elongate fasteners is formed with a shoulder which limits retraction travel of said magnetic stripe reader head bracket and thus of said magnetic stripe reader head relative to said pair of fasteners and thus relative to said card swipe slot and said aperture.

4. A magnetic stripe card reader according to claim 3 and wherein said pair of mutually spaced mounting apertures are sufficiently small as not to be able to pass said shoulders, whereby said shoulders define stops for limiting retraction displacement of said magnetic stripe reader head bracket against urging of said coil springs.

5. A magnetic stripe card reader according to claim 1 and wherein each of said pair of elongate fasteners is formed with a first shoulder, which limits an extent that said fasteners extend beyond said magnetic stripe reader head support base, and a second shoulder, which limits retraction travel of said magnetic stripe reader head bracket and thus of said magnetic stripe reader head relative to said pair of fasteners and thus relative to said card swipe slot and said aperture.

6. A magnetic stripe card reader according to claim 5 and wherein said pair of mutually spaced mounting apertures are sufficiently small as not to be able to pass said second shoulders, whereby said second shoulders define stops for limiting retraction displacement of said magnetic stripe reader head bracket against urging of said coil springs.

7. A magnetic stripe card reader according to claim 1 and also comprising a pair of fastener head engagement sockets for engaging heads of said pair of fasteners for retaining them in desired fixed engagement with said magnetic stripe reader head support base.
