摘要： A cash drawer device includes a command receiving and outputting circuit for receiving a plurality of open commands and outputs the open commands, and a simultaneous open inhibiting circuit for inhibiting the command receiving and outputting circuit from simultaneously outputting more than one of the open commands when more than one of the open commands are simultaneously received by the command receiving and outputting circuit. A first simultaneous open inhibiting circuits includes an exclusive OR gate. A second simultaneous open inhibiting circuit includes first and second D flip-flops. The cash drawer device may further include a concurrent open inhibiting circuit having a timer responsive to one of the open commands for inhibiting the command receiving and outputting circuit from outputting another of the open commands for a predetermined interval. Thus, power consumption of driving a plurality of drawers can be suppressed. The invention also includes a method of controlling cash drawers.
