Abstract A static card reader comprising a card receiving chamber having spaced-apart, generally parallel inner and outer walls, a switching chamber including a plurality of circuit portions, a first printed circuit board, and other printed circuit boards, means for moving said chambers relative to each other from a card inserting position to a card reading position, said means being disposed in a position not to preclude visual observation of the card to the outer wall of said card chamber, and card ejection means operated in response to the return of the chambers to the card inserting position, said ejection means being engageable with the lower edge of the card for elevating it in said card chamber to a position in which it may be manually removed from same. Each circuit portion contained within the switching chamber has a first part disposed upon said first printed circuit board and a second part disposed upon one of the other printed circuit boards. Each second part of each circuit portion includes a switching contact biased to a normally closed position with a corresponding first part of said circuit portion. Each switch actuator has a corresponding switching contact, both of which are formed from a single piece of electrically conducting material. Each switch actuator is adapted to move through corresponding apertures in a punched card or to be precluded from moving through the punched card when engageable with a non-perforated portion of same. Each switching contact, upon being brought into engagement with a corresponding first part of said circuit portion, is constructed for movement across said corresponding first part of said circuit portion thereby effecting a wiping action thereacross to facilitate maintaining good electrical contact between said first and second circuit portions.

Claim 1
Independent Claim
202 words
A circuit switch fOr selectively connecting a contact on a first circuit board to a contact on a second circuit board wherein said second circuit board has an aperture through which a portion of said switch extends for possible engagement with a perforated card, said switch comprising: an anchor portion having two ends with one end connected to said first circuit board; a pair of resilient diverging members which are biasable toward each other, the other end of said anchor portion being connected to one of said diverging members; a generally S-shaped contact portion with the bottom of said Sshaped contact portion integrally connected to the other of said diverging members, the middle region of said S-shaped contact being engageable with said contact on the second circuit board; and an actuating portion connected to the top of said S-shaped contact portion and disposed generally colinearly with said anchor portion, said actuating portion being either receivable through a perforation in the card so that said contact portion is biased into engagement with said contact by said diverging members or engageable with the card to force said contact portion away from said contact in a wiping motion due to bending of said V-shaped portion.

A circuit switch fOr selectively connecting a contact on a first circuit board to a contact on a second circuit board wherein said second circuit board has an aperture through which a portion of said switch extends for possible engagement with a perforated card, said switch comprising: an anchor portion having two ends with one end connected to said first circuit board; a pair of resilient diverging members which are biasable toward each other, the other end of said anchor portion being connected to one of said diverging members; a generally S-shaped contact portion with the bottom of said Sshaped contact portion integrally connected to the other of said diverging members, the middle region of said S-shaped contact being engageable with said contact on the second circuit board; and an actuating portion connected to the top of said S-shaped contact portion and disposed generally colinearly with said anchor portion, said actuating portion being either receivable through a perforation in the card so that said contact portion is biased into engagement with said contact by said diverging members or engageable with the card to force said contact portion away from said contact in a wiping motion due to bending of said V-shaped portion.
Claim 3
Dependent Claim

A circuit switch for selectively connecting a contact on a first circuit board to a contact on a second circuit board wherein said second circuit board has an aperture through which a portion of said switch extends for possible engagement with a perforated card, said switch comprising: an anchor portion having two ends with one end connected to said first circuit board; a resilient V-shaped biasing portion having two ends with one end connected at a first angle to the other end of said anchor portion; a generally S-shaped contact portion with the bottom of said S-shaped contact portion connected to the other end of said V-shaped portion, the middle region of said S-shaped contact portion being engageable with said contact on the second circuit board; and an actuating portion connected to the top of said S-shaped contact portion and disposed generally colinearly with said anchor portion, said actuating portion being either receivable through a perforation in the card so that said contact portion is biased into engagement with said contact by said V-shaped portion or engageable with the card to force said contact portion away from said contact in a wiping motion due to bending of said V-shaped portion.
Claim 4
Dependent Claim
