Abstract

A magnetic stripe reader including a base element defining a first spring seat, a magnetic module support element arranged for limited pivotable motion relative to the base element and defining a second spring seat, a generally truncated conical spring having a first, relatively large diameter end seated in the first spring seat and a second, relatively small diameter end seated in the second spring seat and a magnetic module fixedly mounted onto the magnetic module support element.

First claim

The invention claimed is:

1. A magnetic stripe reader comprising:
a base element defining a first retaining portion;
a support means for providing limited pivotable motion relative to the base element and defining a second retaining portion;
a means for enabling the limited pivotable motion of said support means relative to said base element that has a first end seated in the first retaining portion and a second end seated in the second retaining portion such that the first end has a larger diameter than the second end; and
a means for reading a magnetic stripe fixedly mounted onto the support means.

2. The magnetic stripe reader according to claim 1 , wherein said means for enabling the limited pivotable motion of said support means provides skewed displacement of said support means relative to said base element when said means for reading a magnetic stripe is engaged by a leading edge of a payment card.

3. A magnetic stripe reader comprising:
a base element defining a first spring seat;
a magnetic module support element arranged for limited pivotable motion relative to said base element and defining a second spring seat;
a truncated conical spring having a first, relatively large diameter end seated in said first spring seat and a second, relatively small diameter end seated in said second spring seat; and
a magnetic module fixedly mounted onto said magnetic module support element and comprising a magnetic stripe reader with at least one magnetic stripe reading head;
said magnetic module support element comprising:
a generally planar portion; and
a pair of legs disposed generally perpendicularly to said generally planar portion, each of said pair of legs defining an elongate slot and having a foot portion with a lower surface;

a pair of cylindrical protrusions, on opposite sides of said base element, located in sliding engagement with a corresponding one of said elongate slots associated with one of said pair of legs; and
said magnetic module support element being configured for skewed displacement, relative to said base element, when a leading edge of a payment card initially engages said magnetic module in response to compression of said truncated conical spring.

4. The magnetic stripe reader according to claim 3 , wherein said skewed displacement causes at least a downward displacement of said foot portion of at least one of said pair of legs, wherein the downward displacement is movement of said lower foot portion towards said base element.

5. The magnetic stripe reader according to claim 3 , wherein said leading edge of said payment card causes said skewed displacement of one of said pair of legs when said leading edge contacts said magnetic module.

6. The magnetic stripe reader according to claim 3 , wherein said leading edge of said payment card causes said skewed displacement of both of said pair of legs when said leading edge is fully engaged with said magnetic module.

7. The magnetic stripe reader according to claim 3 , wherein said leading edge of said payment card causes one of said pair of legs to be displaced downward towards said base element.

8. The magnetic stripe reader according to claim 3 , wherein said leading edge of said payment card causes said skewed displacement of both of said pair of legs when said leading edge is fully engaged with said magnetic module.

9. The magnetic stripe reader according to claim 3 , said base element further comprises a central portion comprising a pair of upstanding side portions.

10. The magnetic stripe reader according to claim 9 , wherein said pair of cylindrical protrusions is formed on said pair of upstanding side portions.

11. The magnetic stripe reader according to claim 10 , further comprising:
a pair of protrusions having a partially circular cross section and extending from said pair of cylindrical protrusions.
