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 non-circular sprocket driven by the actuator, wherein the teeth of the non-circular sprocket are not all the same distance from an axis of rotation of the non-circular sprocket;a belt driven by the sprocket, the belt comprising a plurality of links, and the belt configured to circulate within a chamber when driven by the actuator;a plurality of paddles integrally formed with the links of the belt for receiving between pairs of the paddles items to be dispensed, the paddles extending from the belt; 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 when the segmented belt is incrementally advanced and the paddle supporting the item approaches a vertical orientation due to the advancement of the belt. 2. The dispensing mechanism of claim 1, wherein each of the paddles is L-shaped in cross section, and wherein the paddles are pinned together in alternating orientation, with each paddle joined to one adjacent paddle at the corners of the joined L shapes, and each paddle joined to one adjacent paddle at tips of the joined L shapes. 3. The dispensing mechanism of claim 1, wherein the actuator comprises a motor, a solenoid, or a memory metal. 4. The dispensing mechanism of claim 1, 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 actuator and causing the belt to be driven. 5. The dispensing mechanism of claim 2, wherein the teeth of the sprocket form a square, with at least three of the teeth in a straight line. 6. The dispensing mechanism of claim 5, wherein adjacent paddles joined at the tips of their L shapes are parallel for at least part of their travel around the sprocket. 7. The dispensing mechanism of claim 4, wherein the dispenser and the cassette are separable, and wherein the cassette does not include any active electrical components. 8. The dispensing mechanism of claim 4, 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, the light emitter and the one or more receivers positioned such that the light emitted by at least one of the one or more emitters is interrupted by the passage of a dispensed item through the opening. 9. The dispensing mechanism of claim 8, wherein the one or more receivers detect light reflected from a far wall of the opening or from an item being dispensed. 10. The dispensing mechanism of claim 8, wherein the one or more receivers detect light received directly from one or more of the emitters. 11. The dispensing mechanism of claim 4, wherein the cassette includes a wirelessly-readable memory; andthe dispenser includes a reader for reading the wirelessly-readable memory. 12. The dispensing mechanism of claim 4, wherein the cassette further comprises a brake that is automatically engaged when the cassette is removed from the dispenser, the brake hindering movement of the belt when the brake is engaged.
