A unique method and apparatus for dispensing tablets having particular application in the clinical analysis of biological samples. A series of containers are advanced past a plurality of processing stations, one of which is a table dispenser in turn. The processing stations are selectively activated by a controller. A sensor is associated with the tablet dispenser and is arranged to detect whether a tablet has actually entered a container. The sensor is activated only when the tablet dispenser is activated. The controller is responsive to the sensor in dependence upon the condition sensed by the sensor.

A clinical analysis system for analyzing biological samples, including: a plurality of processing stations, a strip of interconnected cuvettes having open mouths, means for advancing said strip of interconnected cuvettes in steps corresponding to the spacing between adjacent cuvettes past said processing stations to align said cuvettes successively with said processing stations in turn, and control means programmed to selectively activate said processing stations as said cuvettes are advanced therepast so that different cuvettes are processed differently from one another as they are advanced past said processing stations, one of said processing stations comprising: a tablet dispensing means including a motor for driving the dispensing means to dispense a tablet, sensing means arranged below the mouth of a cuvette aligned with said tablet dispensing means to sense whether a tablet has entered the cuvette, and signal generating means operatively associated with said sensing means for generating a signal indicating the absence of a tablet, said control means being programmed to activate said tablet dispensing means selectively to dispense tablets only when selected ones of said cuvettes are aligned with said tablet dispensing means by said advancing means such that said tablet dispensing means is activated to dispense tablets into less than all of said cuvettes and said sensing means being activated only when said tablet dispensing means is activated, being activated for a predetermined time each time said motor is activated, whereby a signal indicating the absence of a tablet can only be generated when the motor of the tablet dispensing means is activated to cause the tablet dispensing means to dispense a tablet, said advancing means being operable to advance said cuvette strip independently of the operation of said tablet dispensing means whereby operation of said advancing means is not dependent upon the dispensing of a tablet by said tablet dispensing means, and said control means being responsive to a signal from said signal generating means to vary further operation of said processing stations in a predetermined manner from that programmed to occur in the absence of said signal.
