Embodiments of the present invention will be described below in detail with reference to the drawings. First, FIG. 1 shows a front view of a slot machine 1 as an example of the slot machine according to the present invention. A display window 71 is provided at a predetermined position on the front surface of the slot machine 1, and identification information such as a symbol variably displayed by the variable display device 70 (see FIG. 2) is provided inside the display window 71. Variable display section 5L, middle variable display section 5C, right variable display section 5
R is configured to be able to variably display symbols in three upper and lower stages.

When a player plays a game, the player inserts a coin, which is an example of a value object, from the coin insertion slot 18 when the insertion instruction lamp 19 is lit or blinking. The insertion instruction lamp 19 turns off when three coins are inserted. However, in a regular bonus game to be described later (hereinafter, simply referred to as a bonus game), the light is turned off when one coin is inserted. When one or more coins are inserted, the start lamp 72 is turned on, thereby indicating that the start lever 12 is in a start state in which the start lever 12 can be pressed.

When the player inserts a coin and presses the start lever 12 with the start lamp 72 turned on, the variable display device 70 is variably started, and a plurality of types of variable display units 5L, 5C, and 5R are displayed. The symbols are variably displayed. Next, when the player presses each of the stop buttons 9L (also referred to as a left stop button), 9C (also referred to as a middle stop button), and 9R (also referred to as a right stop button), the corresponding variable display portions 5L are respectively operated. , 5C, and 5R are stopped. When the player does not press the stop buttons 9L, 9C, 9R, each of the variable display units 5L, 5C, 5
R automatically stops sequentially in the priority order of, for example, 5L, 5C, and 5R. Therefore, in the case where it is expected that the game result will be a loss result from the stop result of some of the variable display units, the variable based on the predetermined stop timer can be performed without depressing the stop button 9R or the like. Since the variable display of all the variable display units is automatically terminated when the display time elapses, it is possible to prevent the player from imposing an extra game operation burden.

The slot machine 1 has a normal game (coin game) in which coins are inserted to play a game,
It is also possible to play a credit game using credits described later. In the case of a coin game, if the player inserts one coin from the coin insertion slot 18 and presses the start lever 12, the effective lines of the middle horizontal row in the variable display portions 5L, 5C, and 5R ( Only the hit line) is valid, and the valid line display lamp 21 is lit to notify the player that the line is valid. A game played by betting the value of one coin is called a one-bet game. In the single betting game, when the symbol displayed when the variable display device 70 is stopped is in a predetermined specific display mode on an active line in the middle horizontal row, a payout of a predetermined number of coins or the like is performed.

Here, the mounting piece 112a and the fixing piece 113
a and a method of fixing the mounting piece 112b and the fixing piece 113b will be described with reference to FIG. The rivet 110 as a fixing means used in the present embodiment is called a blind rivet, and a through-passage 115 is formed in the rivet 110 made of aluminum, and a pull pin 116 is inserted into the through-passage 115. It is possible. Pull pin 11
6 is formed at one end with an enlarged diameter portion 116a having a diameter larger than the inner diameter of the through passage 115.
A bent portion 116b having a smaller diameter than the inner diameter of the through-path 115 is formed at the base of 6a.

Next, a method for fixing the mounting piece 112a and the fixing piece 113a using the rivet 110 will be described below. Note that the fixing piece 113b and the mounting piece 112b are fixed by the same method as the fixing method of the fixing piece 113a and the mounting piece 112a, and a description thereof will be omitted. First, as shown in FIG. 7A, the rivet 110 is inserted after the insertion holes 111a and 114a are matched with each other, and in this state, the pulling pin 116 is moved by using a predetermined tool and the arrow in FIG. When pulled in the direction, the retracted enlarged diameter portion 116a is locked to the end of the rivet 110 as shown in FIG. 7B, and the end of the rivet 110 is deformed. When the movement of the retracted enlarged diameter portion 116a is further restricted at a position near the insertion hole 114a of the fixed piece 113a in the through path 115, the mounting piece is formed by the deformed end of the rivet 110 and the head 110c of the rivet 110. 112a and the fixing piece 113a are sandwiched,

FIG. 14 is a schematic diagram showing an example of the configuration of a power supply circuit. In the figure, reference numeral 130 denotes a switch circuit capable of switching the power mainly supplied to the control unit 45 to either an external power supply or a battery 131 as a power storage means, and 132 detects a change in voltage in the external power supply. 5 shows a voltage detection circuit, and when the supply of power from an external power supply is stopped and the voltage falls below a predetermined value, the switch circuit 130 is switched to a battery 131.
Side, the power of the battery 131 is supplied to the control unit 45, and a predetermined signal indicating that the power supply has been stopped is transmitted to the control unit 45 as described later. At this time, the voltage detection circuit 132
Is energized by the battery 131 so that it can operate even when the power is cut off.

In the figure, reference numeral 128 denotes a transistor constituting the reservation circuit 101, which is provided in parallel with the power switch 81, and which supplies power from the switch circuit 130 to the control unit when the power switch 81 is turned on. 45
Is supplied to the control board. Here, when the power switch 81 is turned off, the switch / sensor circuit 55 becomes the reservation circuit 101 having the transistor 128.
The CPU 46 of the control unit 45, which receives the power via the power supply via the communication unit 92, detects that the power switch 81 has been turned OFF and receives the power via the reservation circuit 101. A supply stop signal is sent. Here, the fact that the power supply stop signal has been input is displayed on the display screen of the management computer 96, and it can be seen that the power switch 81 has been operated in the predetermined slot machine 1. Then, when the management computer 96 permits the power supply stop, a power supply stop permission signal is sent to the CPU 46, and the CPU 46 receiving the power supply stop signal stops the power supply via the reservation circuit 101.

Here, for example, a predetermined error sound is output when the connector of the cable of the inserted coin sensor 36 and the connector of the paid-out coin sensor 39 are released or inserted. A person who intends to perform unauthorized processing on each sensor in the machine 1 or the like may turn off the power when performing unauthorized processing in order to avoid outputting an error sound.

However, even when, for example, an operation of stopping the power supply by the power switch 81 is performed, the reservation circuit 101 having the power switch 81 and the transistor 128 configured in parallel with the power switch 81
The power supply stop is temporarily reserved in the control unit 45. During this time, the control unit 45 sends a signal to the external management computer 96 to the effect that the power supply has been stopped to the management computer 96. It is possible to reliably confirm that the supply stop operation has been performed. Therefore, it is possible to detect that the power supply has been turned off by the power switch, that is, there is a possibility that an illegal act has been performed.

Regardless of the operation of the power switch 81, for example, when the power supply is stopped due to the removal of the power plug, the switch circuit 130 is switched to the battery side by the voltage detection circuit 132, and the control unit is turned off. Power is supplied to the battery 45 from the battery 131. Accordingly, upon receiving this power, the voltage detection circuit 132 directly sends a signal to the control unit 45 that power supply has been stopped, and the control unit 45, which is also supplied with power from the battery 131, The signal can be output to the management computer 96. Note that the voltage detection circuit 132 outputs a signal indicating that the supply of power has been stopped to the external management computer 96 directly without passing through the control unit 45.
May be output.

The battery 1 as such power storage means
If the power supply is stopped by providing the power supply switch 81 instead of the retaining circuit 101, the switch / sensor circuit 55 receives the power from the battery 131. By detecting the operation of the power switch 81, it is possible to output to the outside that the power supply has been stopped. In the present embodiment, the battery 131 is used as the power storage means. However, the present invention is not limited to this, and a capacitor or the like capable of storing predetermined power may be used.

In this case, a signal indicating that the power supply has been stopped is sent to the external management computer 96, and the management computer 96 can confirm that the power supply has been stopped. The fact that the power supply has been stopped is displayed as an error on an appropriate display device provided in the slot machine 2, for example, or displayed by turning on the game effect lamp 24 or the like, or in a predetermined storage unit. It is sufficient that the error data is recorded as error data and can be output to a recording medium or the like as appropriate, so that external data can be confirmed.
