PURPOSE:To easily prepare a rotary drum part without spending working labor by fitting a ring band body part along the external periphery of a drum-shaped rotary main body part, and making a magnetically detected part to be built-in at a concave part formed at the ring band body part. CONSTITUTION:A rotary drum 1 consists of a drum main body 11, a holding rubber belt 12, and a pattern seal 13. A pair of flange parts 113 are formed at the drum main body 11 and respective edge surfaces, the space between the pair is made into a gap part 112, and the rubber belt is fitted. When rotary drums 11-13 are rotated, the respective hole elements of magnetic sensor parts 21-23 detect corresponding magnets 140-149, generate pulses, first, a resetting detecting circuit 20 outputs the resetting pulses at the position of a reference hole 120, resets a counter 22, and next, a counting detecting circuit 21 generates and outputs the counting pulses at the position of respective housing holes 121-129. Consequently, the contents of the counter 22 when the rotary drum 1 is stopped are correspond to the types of the patterns displayed to the player. |
