PROBLEM TO BE SOLVED: To solve a problem of a game machine such as a slot machine that the work efficiency is deteriorated if the lock structure is secure, so that the simplification of the structure is difficult. SOLUTION: In the slot machine, a slot unit is made to pop out slightly, associated with the unlocking operation or the opening of a front door. The unit stored in a casing is always energized in the direction of take-out with a spring, and a lock means prevents the unit from popping out. The lock means interlocks with the unlocking operation or the front door opening, and pops out when the unit is taken out. COPYRIGHT: (C)2004,JPO
