<P>PROBLEM TO BE SOLVED: To provide a game machine which is excellent in protection performance against unfair unlocking. <P>SOLUTION: In the reel-type game machine 1 of a ball-use type, a front door 3 is openably/closably supported on an outer frame 2. A locking device to lock the front door 3 with the outer frame 2 is provided on the back-surface side of the front door 3. The locking device includes: a cylinder lock 930 operated by a key; and a locking member capable of coming in/out in a right and left direction linking to the motion of the cylinder lock 930. The locking member is projected toward the inner side face of the outer frame 2 to be locked to a receiving clasp provided on the inner side face, and thereby the opening of the front door 3 is controlled. On the other hand, locking member is retracted to be separated from the receiving clasp, and thereby the opening of the front door 3 is permitted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
