An indicator device for a table dispenser has a first cylindrical rotatable member defining an aperture, a second cylindrical rotatable member arranged concentrically with respect to the first member, a third cylindrical member relatively fixed with respect to and concentric with the first and second members, means coupling the first and second members for rotation together in a first direction of rotation from a first position of the first member in which access through the aperture is not possible to a second position of the first member in which access through the aperture is possible for dispensing a tablet, means coupling the second and third members to prevent the rotation of the second member in the direction of rotation opposite to the first direction during the rotation of the first member from the second position to the first position and means to indicate, upon the restoration of the first member to its first position after it has been rotated to the second position, the time that a tablet is next due to be dispensed.
