1. A device for dispensing articles, the device comprising: a conveying member comprising n receptacles, wherein a number m of said receptacles is a blank receptacle which is unable to receive an article, where m is at least 1; of which n−m are suitable for receiving articles, the receptacles being movable between an article receiving position and an article dispensing position;a sensor for sensing the presence of articles in the receptacles, the sensor positioned between the receiving position and the dispensing position; andwhere the sensor is configured to detect an empty receptacle as equivalent to a blank receptacle such that the maximum number of detectable articles conveyed once n receptacles have passed the sensor is n−m. 2. A device according to claim 1, wherein the conveying member is configured to convey the receptacles in a substantially annular path. 3. A device according to claim 1, wherein the blank receptacle comprises a receptacle deactivated by means of a baffle, wherein the baffle is integrally formed with one or more defining walls of the receptacle. 4. A device according to claim 1, wherein the sensor comprises a photocell. 5. A device according to claim 1 further comprising a housing in which a storage chamber for the storage of articles to be dispensed is contained or is containable, wherein the storage chamber is provided in a removable cassette that is manually or automatically releasably engageable within the housing. 6. A device according to claim 1, further comprising a processor configured to receive data from the sensor indicative of the presence or absence of an article in one or more of the receptacles. 7. A device according to claim 1, further comprising a motor for operating the conveyor to convey the receptacles between the receiving position and the dispensing position, wherein the motor is operable to move the conveyor in increments of 1/n of the effective length of the conveyor; and/or wherein the motor is arranged in communication with and is at least partly controllable by a processor and/or wherein the processor is configured to operate the motor to dispense a predetermined number of articles at one or more predetermined times; and/or wherein the processor is programmable to provide the number of articles to be dispensed and the one or more times at which those articles are to be dispensed. 8. A medication dispensing device comprising the device of claim 1, where the articles comprise discrete units of medicine, and the device contains a plurality of discrete units of medicine. 9. A device according to claim 3, wherein the baffle which is comprised in the blank receptacle is transparent to at least the range of wavelengths of light detectable by the photocell and/or wherein infra-red light is detectable to the photocell. 10. A device according to claim 6, wherein the processor is configured to provide an alert if the sensor indicates the presence of n articles conveyed once n receptacles have passed the conveyor, the alert to indicate the malfunction of the sensor. 11. A device according to claim 6, wherein the processor is configured to calculate and store information indicative of the number of articles dispensed during a predetermined period and at predetermined times. 12. A device according to claim 10, wherein the alert comprises one or more of an audible alert, a kinetic alert such as a vibrating alert, a visual alert such as a written or graphic alert or an illuminated light emitting device. 13. A device according to claim 7, wherein the processor is configured to perform a test routine comprising, without dispensing any articles, activating the motor to move n receptacles past the detector and assessing the number of articles held in receptacles to provide data indicative of one or both of (i) the number of articles remaining to be dispensed by the device and (ii) the functioning of the sensor. 14. A method of identifying a fault in a sensor, the method comprising; moving n receptacles past the sensor to detect the number of receptacles containing articles, where n−m of said receptacles being suitable for holding articles and where the m receptacles unsuitable for holding articles are detectable by the sensor as equivalent to empty receptacles suitable for holding articles, where m is at least 1;(ii) providing an alert to the user if the number of receptacles detected to be containing articles is greater than n−m. 15. A hardware module configured to perform the method of claim 14. 16. A computer program stored in a tangible medium, which when run on a computer, causes the computer to configure any apparatus, including a circuit, controller, converter, or device disclosed herein to perform the method according to claim 14. 17. A method of dispensing articles from a device the method comprising: (i) moving n receptacles from a receiving position to a dispensing position, where n−m of said receptacles being suitable for holding articles and where the m receptacles unsuitable for holding articles are detectable by a sensor as equivalent to empty receptacles suitable for holding articles, wherein m is at least 1 the sensor being positioned between the receiving position and the dispensing position;(ii) using the sensor to detect the number of receptacles containing articles;(iii) providing an alert to the user if the number of receptacles detected to be containing articles is greater than n−m. 18. A method according to claim 17, comprising dispensing up to a predetermined maximum number of articles within a prescribed period of time. 19. A hardware module configured to perform the method claim 18. 20. A computer program stored in a tangible medium, which when run on a computer, causes the computer to perform the method according to claim 18.
