ABSTRACT:
A method of waking up an in-counter bar code scanner from its standby mode comprises providing a sensor assembly attached to a touch plate. The sensor assembly comprises an oscillating magnet member affixed at one end and a permanent magnet attached at an opposite free end at the end of a flexible member. When a user touches the touch plate, the impact force exerted on the touch plate is transmitted to the oscillating magnet member causing the magnet to oscillate inducing an electrical signal in a pick-up coil provided near the magnet and wakes up the bar code scanner.
