ABSTRACT:
A single piece trigger and knock off mechanism for a switch operated card printer includes a lever integrally connected to a resilient mounting bracket which provides a first flexural pivot. The lever comprises a pair of integrally connected arms, each provided with an ear. A moving card contacts the ear on one arm, causing the lever to swing about the first flexural pivot. As the lever swings, the ear on the other arm contacts a switch which triggers a card printer solenoid. The solenoid operates a card printer hammer. The card printer hammer is driven towards the card when the solenoid is triggered. As the hammer is driven towards the card, a moveable element associated with the card printer strikes the arm whose ear is in contact with the switch, causing the arm to swing about a second flexural pivot formed by a bend in the arm. As the arm swings, the ear releases the switch. This knocks off the solenoid just before the hammer contacts the card.
