PURPOSE:To prevent a generation of defective by providing an all color sensor composed of multiple light axes and calibrating the position of a tablet having core automatically by linking with a movable tablet supply device. CONSTITUTION:A large number of mortar 2 is provided at constant intervals and a tablet supply device 6 which synchronizes with a rotary disk 1 holds and supplies a tablet having a core 7. A multiple light axes sensor 20 radiates four signals to directions of R, L, C, S and has a fiber part 20c and a detecting part 20 to detect. The difference of color between the first powder 5a in the mortar 2 of the rotary disk 1 and a tablet 7 thereon are detected by the sensor 20 and the rate of eccentricity of the tablet 7 is discriminated, and a driving control part 26 of the tablet supply device 6 calibrates the position of the device 6. The generation of defective of the tablet having a core is prevented by this method. |
