<p>PROBLEM TO BE SOLVED: To detect whether or not a shooting device is set at a right position with respect to a game board and determine excess/deficiency, namely, whether or not the number of all the enclosed game balls is appropriate in an enclosed type game machine in which the shooting device is movably disposed at an upper part of a body frame.SOLUTION: The game machine includes: a position detection sensor 180 for determining whether or not a ball shooting device 29 movably provided at the upper part of a body frame 2 is located at a normal position with respect to a game board 5; and a ball information control board 110 for controlling actuation of the ball shooting device 29. On the condition that it is detected via the position detection sensor 180 that the ball shooting device 29 is located at the normal position with respect to a game board 8, a ball information control MPU 111 determines the excess/deficiency, namely, whether or not the number of all the enclosed game balls is appropriate and, on the condition that it is determined that the number of all the enclosed game balls is appropriate, permits the actuation of the ball shooting device 29.</p> |
