Magnetic card reader
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.
1. 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, the 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
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, said truncated conical spring enabling said limited pivotable motion of said magnetic module support element relative to said base element; and
a magnetic module fixedly mounted onto said magnetic module support element.
2. A magnetic stripe reader comprising:
a base clement 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,
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
said base element comprising:
a pair of cylindrical protrusions; and
a pair of corresponding protrusions,
each of said pair of cylindrical protrusions and each of said pair of corresponding protrusions being located in sliding engagement with a corresponding one of said elongate slots associated with one of said pair of legs.
3. The magnetic stripe reader according to claim 2 and wherein said sliding engagement guides and limits mutual spring loaded displacement between said base element and said magnetic module support element.
4. 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,
said magnetic module support element comprising:
a generally planar portion;
a pair of legs disposed generally perpendicularly to said generally planar portion, each of said pair of legs defining an elongate slot; and
a retaining tab extending in a plane parallel to the plane of said generally planar portion; and
said base element comprising a tab engagement surface portion engaging said retaining tab.
5. The magnetic stripe reader according to claim 1 and wherein said truncated conical spring provides skewed displacement of said magnetic module support element relative to said base element when said magnetic stripe reader is engaged by a leading edge of a payment card.
6. The magnetic stripe reader according to claim 2 and wherein said truncated conical spring provides skewed displacement of said magnetic module support element relative to said base element when said magnetic stripe reader is engaged by a leading edge of a payment card.
7. The magnetic stripe reader according to claim 4 and wherein said truncated conical spring provides skewed displacement of said magnetic module support element relative to said base element when said magnetic stripe reader is engaged by a leading edge of a payment card.
