Abstract
In one embodiment of the present invention, a cash drawer is provided which can have its drawer latch solenoid actuated by one of a plurality of different voltages. The plurality of different voltages can include at least three different voltages. In another illustrative embodiment, the cash drawer of the present invention provides a multi-voltage cash drawer with fly-back protection.
Claims21
A cash drawer comprising:
- a housing;
- a drawer slidably mounted in the housing;
- a latch configured to hold the drawer in a closed position;
- and
- an actuator coupled to the latch to move the latch between an unlatching position and a latching position, the actuator being configured to actuate upon receiving an input signal at any one of at least three energization potentials.
2 more elements
A cash drawer, comprising:
- a housing;
- a drawer reciprocally mounted within the housing;
- a latch movable between a latching position holding the drawer in the housing and an unlatching position;
- an actuator coupled to the latch to move the latch between the latching and unlatching positions based on a predetermined energization signal;
- and
- an energization circuit receiving an input signal at any one of a plurality of voltage potentials and applying the predetermined energization signal to the actuator, the energization circuit including a plurality of coils providing the predetermined energization signal to the actuator and a selection circuit applying the input signal to one or more of the coils and de-energizing the coils, inhibiting application of de-energizing current to components remote from the cash drawer.
3 more elements
A cash drawer latch assembly, in a cash drawer comprising:
- a latch movable between a latching position and an unlatching position;
- and
- an actuator energizeable to move the latch between the latching and unlatching positions, the actuator including a plurality of coils and a diode circuit the diode circuit receiving an input signal at one of a plurality of voltages, and de-energizing the coils inhibiting application of de-energization to components external to the cash drawer.
