Next, the operation of the slot machine constructed as described above will be explained. First, when one to three medals are inserted into the medal slot 21 shown in FIG. Each of the stop levers 63 is placed in a non-operating position as indicated by chain lines in FIG.

In this state, each clutch plate 49, 51A to 51C and each pattern drum 8a to 8c are urged to move toward the retaining ring 50 based on the spring force of each compression spring 52, and are held in a state in which they are connected to each other. ing. Next, when one of the start switch levers 22 is pressed down, the step motor 55 is rotated in a predetermined direction under the control of a control device (not shown), and the motor shaft 56 and drive pulley 5 are rotated.
7. The drive shaft 42 is rotated via the toothed belt 59 and the driven pulley 53, and together with the drive shaft 42, the clutch plates 49, 51A to 51C and the pattern drums 8a to 8c are rotated in a predetermined direction.

Subsequently, when each stop switch button 23 is pressed, the control device is activated and each solenoid 61 is momentarily energized in order to stop the rotation of the pattern drums 8a to 8c corresponding to each stop switch button 23. Based on the excitation of each solenoid 61,
The plunger 67 is sucked downward, and each stop lever 63 is moved from the non-operating position shown by the chain line in FIG. 5 to the non-operating position shown by the solid line in FIG. It is rotated to the working position. The solenoid 61 is held at the operating position by the attractive force of the permanent magnet within each solenoid 61. Based on the rotation of each stop lever 63, the locking protrusion 64 engages the engagement recess 46 of the ratchet wheel 47.
a, and the rotation of each pattern drum 8a to 8c is stopped. At this time, with slippage occurring between each pattern drum 8a to 8c and each clutch plate 49, 51A to 51C, the drive shaft 42 and each clutch plate 4
9, 51A to 51C are continuously rotated as one unit.
After all the pattern drums 8a to 8c are stopped based on the operation of the stop lever 63,
The rotation of the step motor 55 is stopped, and the drive shaft 4
2 is stopped.

When the pattern drums 8a to 8c are stopped, the pattern located on each combination line 18 is determined by a photo interrupter 73 for detecting the origin position and a photo interrupter 74 for detecting the pattern.
CPU in the control device based on the signal output from
(central processing unit). and,
When the combination of symbols located on the combination line 18 matches the combination of the symbols on the symbol display section 20, a predetermined signal is input from the control device to the ejection device 11, The ejection device 11 is activated and a predetermined number of prize medals are ejected into the tray 28.

Further, in this embodiment, since the operation protrusion 66 of the stop lever 63 protrudes forward from the support bracket 60 and is disposed at the front opening of the housing section 6 at the center of the housing 1, the opening operation of the front panel 15 is not possible. This allows the operating protrusion 66 to be exposed. In this exposed state, the operating protrusion 66 can be moved from the working position shown by the solid line in FIG. 5 to the non-working position shown by the chain line against the attractive force of the permanent magnet in each solenoid 61. , the locking protrusion 64 of each stop lever 63 can be disengaged from the engagement recess 46a of the ratchet wheel 47. In this state, each pattern drum 8a~
8c can be rotated freely, which is convenient for maintenance, replacing patterns, etc. Thereafter, when the operation protrusion 66 is moved downward to the operating position shown in FIG. Since the locking protrusion 64 of each stop lever 63 is engaged with the engagement recess 46a of the ratchet wheel 47, each pattern drum 8a-
8c can be placed at any position.
