Mechanisms for dispensing items such as medications and medical supplies. Different mechanisms may be tailored to dispensing different kinds of items, for example medications in single dose packages, vials, syringes, or other similarly-shaped items. The dispensers may be placed in a dispensing unit that includes a lockable restock drawer and a dispense drawer into which items are dispensed by the dispensing mechanisms. The various kinds of dispensing mechanisms may be installed in the restock drawer in any workable proportion and arrangement. The dispensing mechanisms include multiple sensing technologies for tracking and inventory of items and for accurate sensing of items as they are dispensed.

1. A dispensing mechanism, comprising: a connector for receiving electrical signals from a cabinet in which the dispensing mechanism is installed;an actuator that operates in response to the electrical signals;a belt driven by the actuator;a plurality of spaced-apart paddles for receiving between the paddles items to be dispensed, the paddles being moved by the belt to circulate within a chamber; anda housing defining the chamber and defining an opening at the bottom of the chamber, such that a single item drops from between its respective paddles and through the opening and out of the dispensing mechanism when the belt is incrementally advanced and the paddle supporting the item approaches a vertical orientation due to the advancement of the belt;wherein the connector and actuator are comprised in a dispenser, and the belt, paddles, and housing are comprised in a cassette, and wherein the dispensing mechanism further comprises:a driving gear in the dispenser turned by the actuator; anda driven gear in the cassette, the driven gear being driven by the driving gear and causing the belt to be driven. 2. The dispensing mechanism of claim 1, wherein the actuator comprises a motor, a solenoid, or a memory metal. 3. The dispensing mechanism of claim 1, wherein the dispenser and the cassette are separable, and wherein the cassette does not include any active electrical components. 4. The dispensing mechanism of claim 1, wherein the dispenser further comprises: a light emitter directed across the opening at the bottom of the chamber; andone or more receivers that detect light from the light emitter reflected from a far wall of the opening, the light emitter and the one or more receivers positioned such that the light detected by at least one of the one or more receivers is interrupted by the passage of a dispensed item through the opening. 5. The dispensing mechanism of claim 1, wherein: the plurality of paddles comprises at least 32 paddles; andthe cassette displaces an overall volume of less than 900 cubic centimeters. 6. The dispensing mechanism of claim 1, wherein the cassette displaces less than 30 cubic centimeters for each item stored in the cassette at full capacity. 7. The dispensing mechanism of claim 1, wherein the cassette includes a wirelessly-readable memory chip; andthe dispenser includes a reader for reading the wirelessly-readable memory chip. 8. The dispensing mechanism of claim 1, wherein the belt is segmented, and each of the plurality of paddles is integrally formed with a respective segment of the belt. 9. The dispensing mechanism of claim 1, wherein the plurality of paddles comprises at least 32 paddles. 10. The dispensing mechanism of claim 1, further comprising a sensor that directly measures motion of the dispensing mechanism. 11. A dispensing mechanism, comprising: a connector for receiving electrical signals from a cabinet in which the dispensing mechanism is installed;an actuator that operates in response to the electrical signals;a belt driven by the actuator;a plurality of spaced-apart paddles for receiving between the paddles items to be dispensed, the paddles being moved by the belt to circulate within a chamber, some of the paddles moving upward on one side of the chamber while other of the paddles move downward on an opposite side of the chamber when driven by the belt; anda housing defining the chamber and defining an opening at the bottom of the chamber, wherein walls of the housing constrain items on both sides of the chamber to remain between their respective paddles until the items are dispensed;and wherein a single item drops from between its respective paddles and through the opening and out of the dispensing mechanism when the belt is incrementally advanced and the paddle supporting the item approaches a vertical orientation at the bottom of the chamber due to the advancement of the belt;and wherein the connector and actuator are comprised in a dispenser, and the belt, paddles, and housing are comprised in a cassette, and wherein the dispensing mechanism further comprises:a driving gear in the dispenser turned by the actuator; anda driven gear in the cassette, the driven gear being driven by the driving gear and causing the belt to be driven. 12. The dispensing mechanism of claim 11, wherein the dispenser and the cassette are separable, and wherein the cassette does not include any active electrical components. 13. The dispensing mechanism of claim 11, wherein the dispenser further comprises: a light emitter directed across the opening at the bottom of the chamber; andone or more receivers that detect light from the light emitter reflected from a far wall of the opening, the light emitter and the one or more receivers positioned such that the light detected by at least one of the one or more receivers is interrupted by the passage of a dispensed item through the opening. 14. The dispensing mechanism of claim 11, wherein the cassette includes a wirelessly-readable memory chip; andthe dispenser includes a reader for reading the wirelessly-readable memory chip. 15. The dispensing mechanism of claim 11, wherein the belt is segmented, and each of the plurality of paddles is integrally formed as a single piece with a respective segment of the belt. 16. A dispensing mechanism for dispensing items, the dispensing mechanism comprising: a dispenser including a connector for receiving electrical signals, an actuator that operates in response to the electrical signals, and a driving gear turned by the actuator;a cassette including a belt, a driven gear, a housing defining a chamber, and a plurality of spaced-apart paddles;wherein the driven gear in the cassette is driven by the driving gear in the dispenser, causing the belt to be driven;wherein the plurality of spaced-apart paddles are configured to receive between the paddles items to be dispensed, the paddles being moved by the belt to circulate within the chamber;wherein the housing defines an opening at the bottom of the chamber, such that a single item drops from between its respective paddles and through the opening and out of the dispensing mechanism when the belt is incrementally advanced and the paddle supporting the item approaches a vertical orientation due to the advancement of the belt;and wherein the cassette does not include any active electrical components and the dispenser and cassette are separable, such that the dispensing mechanism can be replenished with items to dispense by removing the cassette and replacing it with a cassette containing items to be dispensed. 17. The dispensing mechanism of claim 16, wherein the actuator comprises a motor, a solenoid, or a memory metal. 18. The dispensing mechanism of claim 16, wherein the dispenser further comprises: a light emitter directed across the opening at the bottom of the chamber; andone or more receivers that detect light from the light emitter reflected from a far wall of the opening, the light emitter and the one or more receivers positioned such that the light detected by at least one of the one or more receivers is interrupted by the passage of a dispensed item through the opening. 19. The dispensing mechanism of claim 16, wherein the cassette includes a wirelessly-readable memory chip; andthe dispenser includes a reader for reading the wirelessly-readable memory chip.
