To perform the detection of the numbers mahjongg chips by kinds with high accuracy and facilitate an aggregating work by a simple constitution by detecting individually mahjongg chips stored in aligning states by a plurality of magnetic detection means and calculating a holding point in response to an output signal from each magnetic detection means.
A player receiving mahjongg chips 1 by kinds stores the chips 1 by kinds in plural kinds of storing pocket parts 10a, 10b ... storing the different kinds of chips 1 according to the kinds in a storing container 10. When the storing container 10 is closed by be rotated by a prescribed angle after the chips 1 are stored, the plurality of the chips 1 stored in each storing pocket part receive an action of an inclined inner wall and are piled in aligning states. At this time, the center of each chip 1 is matched with a disposing location of each hole element 23a, 23b of each magnetic sensor substrate 20a, 20b ...and magnet pieces buried at both the ends of each chip 1 are detected by each hole element 23a, 23b. Therefore, the chips 1 are detected for every kind and an aggregating result is calculated from each detection signal.
