<P>PROBLEM TO BE SOLVED: To provide a Pachinko game machine which can securely detect that a movable body reaches a target position. <P>SOLUTION: The Pachinko game machine 1 includes the movable body 56, a drive means 75 to drive the movable body, a photosensor (position detecting means) 36 to detect a position of the movable body, and a performance control board (detection signal processing means) 22 to read a detection signal from the photosensor. The performance control board 22 stops the drive means when the detection signal indicates that a prescribed signal pattern indicating a light shielding state (second detection state) for a prescribed time (1 msec) or longer after indicating a light receiving state (first detection state) for the prescribed time (1 msec) or longer. When a signal pattern to repeat the light shielding state and the light receiving state at intervals shorter than the prescribed time (1 msec) is detected between a signal pattern indicating the light receiving state for the prescribed time (1 msec) or longer and a signal pattern indicating the light receiving state for the prescribed time (1 msec) or longer, the performance control board 22 determines that the prescribed signal pattern is received. <P>COPYRIGHT: (C)2012,JPO&INPIT |
