<p><P>PROBLEM TO BE SOLVED: To provide a game machine in which operation conditions can be changed mainly by a game parlor side without newly providing a switch for changing the operation conditions. <P>SOLUTION: This Pachinko machine 10 is provided with a second normal winning port sensor SE2 and a main CPU (central processing unit) 31a. The second normal winning port sensor SE2 detects the entry of a game ball, and the main CPU 31a counts the number of the entries of the game balls on the basis of an entry detected result by the second normal winning port sensor SE2 and also measures time after the main CPU 31a starts counting. The main CPU 31a discriminates whether or not two or more game balls enter within a prescribed time on the basis of the counted number of the entries and the measured time. In the case that the main CPU 31a discriminates the entry of the two or more game balls within the prescribed time, the operation conditions of the Pachinko machine 10 are changed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
