Abstract

An improvement to a card gate for a magnetic card feeder is disclosed whereby the close tolerance on perpendicularity between the card gate and the floor of the card feeder is eliminated. With reference to the prior art of Figure 1, the prior art square gate 10 is shown in operative relationship to the floor 12 of a magnetic or punch card feeder. Gap 14 between gate 10 and floor 12 must be set and maintained at a predetermined value for proper feeding of cards from the card feeder. Because of the shape of gate 10, the value of gap 14 is affected by the orientation angle 16 of gate 10 with respect to floor 12. Assuming the sides of gate 10 are square, orientation angle 16 must be set and maintained at 90 degrees with a close degree of tolerance.

An improvement to a card gate for a magnetic card feeder is disclosed whereby the close tolerance on perpendicularity between the card gate and the floor of the card feeder is eliminated.

With reference to the prior art of Figure 1, the prior art square gate 10 is shown in operative relationship to the floor 12 of a magnetic or punch card feeder. Gap 14 between gate 10 and floor 12 must be set and maintained at a predetermined value for proper feeding of cards from the card feeder. Because of the shape of gate 10, the value of gap 14 is affected by the orientation angle 16 of gate 10 with respect to floor 12. Assuming the sides of gate 10 are square, orientation angle 16 must be set and maintained at 90 degrees with a close degree of tolerance.

The improvement in Figure 2 discloses a circular or disk gate 20 in operative relationship with the floor 22 of a magnetic or punch card feeder. Gap 24 between gate 20 and floor 22 must be set and maintained within tolerance, but the previous orientation angle 16 (Figure 1) is eliminated.
