A tablet detecting system ascertains whether a tablet exists in a receiving hole of a loader unit used for a molding tablet supplying apparatus or, if exists, whether the tablet has a standard size, by using a mechanical contact manner. The tablet detecting system has a push rod, a contact head, an insulation plate, a conductive assembly and a control unit. The push rod is inserted into the receiving hole and moves upward just as high as the tablet. The contact head is formed on a top of the push rod and the insulation plate is located over the contact head. The conductive assembly is formed in the insulation plate and the control unit is electrically connected to the conductive assembly. When the tablet in the receiving hole has a standard size, the contact head mechanically touches the conductive assembly and gives electrical connection to the conductive assembly, and the control unit senses the electrical connection. The conductive assembly may be a pair of conductive pads formed separately on a bottom surface of the insulation plate, or a pair of plungers inserted into a pair of cylindrical bodies each formed in the insulation plate and spaced apart from each other.
