Abstract
Abstract A card reader 10, is provided for temporary electrical connection of a card 70 to a printed circuit board. The card reader 10, features a cover 14, which is hingeably mounted to a base 12 at a first end 28. The cover 14, is biased such that its bottom surface 26 is spaced apart from the base 12 at a second end 29. Card support projections 18 are formed from the cover 14, and act in combination with an actuator 20 which extends from the base 12 to draw the cover 14, towards the base 12 upon insertion of a card 70. As the cover 14 is drawn towards the base 12, a switch actuating projection 18,19 actuates a switch. The switch is configurable to be either normally open or normally closed and is changeable between such configurations by simply replacing an interchangeable switch contact 33.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
190 words
A card reader having a base which supports electrical contacts and a card receiving area comprising: a cover being hingeably mounted to the base at a first end and biased to be spaced apart from the base at a second end, the cover having an inner surface proximate the card receiving area, an outer surface opposite the inner surface, a card support disposed on the inner surface proximate the second end, a first switch actuating projection disposed proximate the second end, and at least one second switch actuating projection disposed adjacent the first switch actuating projection, a permanent switch contact being mounted to the base, an interchangeable switch contact being mounted to the base and having a free end positioned for electrical connection with the permanent switch contact whereby a card is insertable into the card receiving area from the first end until it first engages the card support and then engages a cover actuating surface of the base to draw the card and the second end of the cover toward the base while simultaneously causing one of the actuating projections to engage and actuate one of the switch contacts.
Claim 2
Dependent Claim
190 words
A card reader having a base which supports electrical contacts and a card receiving area comprising: a cover being hingeably mounted to the base at a first end and biased to be spaced apart from the base at a second end, the cover having an inner surface proximate the card receiving area, an outer surface opposite the inner surface, a card support disposed on the inner surface proximate the second end, a first switch actuating projection disposed proximate the second end, and at least one second switch actuating projection disposed adjacent the first switch actuating projection, a permanent switch contact being mounted to the base, an interchangeable switch contact being mounted to the base and having a free end positioned for electrical connection with the permanent switch contact whereby a card is insertable into the card receiving area from the first end until it first engages the card support and then engages a cover actuating surface of the base to draw the card and the second end of the cover toward the base while simultaneously causing one of the actuating projections to engage and actuate one of the switch contacts.
Claim 3
Dependent Claim
22 words
The card reader as recited in claim 1 wherein the first switch actuating projection extends from the card support toward the base.
Claim 4
Dependent Claim
53 words
The card reader as recited in claim 1 further comprising at least one card guide member extending from the outer surface of the cover toward the base into the card receiving area whereby the guide member is profiled to receive a side edge of the card for guiding it toward a read position.
Claim 5
Dependent Claim
19 words
The card reader as recited in claim 3 wherein the second switch actuating projection extends from the guide member.
Claim 6
Dependent Claim
22 words
The card reader as recited in claim 1 wherein the interchangeable switch contact is structurally the same as the permanent switch contact.
Claim 7
Dependent Claim
39 words
The card reader as recited in claim 1 wherein the interchangeable switch contact is profiled to engage a pair of second switch actuating projections of the cover as the second end of the cover is drawn toward the base.
Claim 8
Dependent Claim
70 words
The card reader as recited in claim 5 or 6 wherein the interchangeable switch contact is biased to be in contact with the permanent switch contact before insertion of the card into the reader and the second actuating projection engages the interchangeable switch contact causing disengagement thereof from the permanent switch contact as the card is fully inserted into the read position and the cover is drawn toward the base.
Claim 9
Dependent Claim
20 words
The card reader as recited in claim 1 wherein the interchangeable switch contact is narrower than the permanent switch contact.
Claim 10
Dependent Claim
40 words
The card reader as recited in claim 1 wherein the interchangeable switch contact is profiled to pass between a pair of second switch actuating projections of the cover as the second end of the cover is drawn toward the base.
Claim 11
Dependent Claim
70 words
The card reader as recited in claims 8 or 9 wherein the interchangeable switch contact is biased to be spaced apart from the permanent switch contact before insertion of the card into the reader and the first actuating projection engages the interchangeable switch contact causing engagement thereof with the permanent switch contact as the card is fully inserted into the read position and the cover is drawn toward the base.
Claim 12
Dependent Claim
31 words
The card reader as recited in claim 1 wherein the cover further comprises a pair of mounting arms extending along opposite sides thereof for engaging respective side surfaces of the base.
