is held in position 82a by a spring force not shown gate 82 includes a lip 93 which acts as a stop by contacting a portion of top plate 76 as shown in fig8 referring to fig6 the dispensing motor 56 is activated under software control until switch actuator 46 is on the round part of gate hub 78 which causes the contacts of limit switch 44 to close thereby powering the dispensing motor 56 as the dispensing motor rotates the gate hub 40 rod mounting pin 94 retracts gate rod 80 overcoming the spring force holding the gate 82 in position 82a causing gate 82 to pivot to position 82b shown in fig8 this allows the key card 74 to fall as shown by position 74b the key card 74 falls into a chute not shown which leads to the tray 20 in fig1 wherefrom the person can remove the key card after the key card 74 has fallen past the gate 82 the dispensing motor 56 continues rotating the gate hub 78 such that the retracting force on gate rod 80 is eventually removed allowing gate 82 to return to position 82a due to the spring force disposed to hold gate 82 in position 82a the dispensing motor 56 continues to rotate until the switch actuator 46 again encounters the.
