Abstract: A fruit machine has its reels operated by a spring-biased pull handle. This actuates a switch (31) at the limit of its pull against the spring, to energise stepper motors which drive the reels. To simulate the old-fashioned mechanical type, where tentative, incomplete pulls cause the reels to shift fractionally, the handle has associated sensors (35) which give pulse information on the extent and direction of handle movement. This is used to operate the stepper motors, which move the reels in sympathy through a small arc. A pawl (8) and ratchet (3) associated with the handle give further simulation of a purely mechanical reel triggering device.
