Description

[Detailed explanation of the invention] This invention allows the rotation speed of the reels to be changed in each game depending on how the player operates the start lever (or start button), respecting the player's skill and interest. Our goal is to provide you with interesting slot machines.

In order to achieve the above object, the present invention is a slot machine in which multiple reels with multiple types of symbols displayed on the outer periphery are rotated by a stepping motor, and each reel is stopped by a stop button. A detection means for detecting the speed or variation amount of the movable part is provided, and a control device is provided for controlling the number of pulses per unit time for driving the stepping motor based on the detection signal of the detection means. The reel is characterized in that the rotational speed of the reel is changed depending on the speed and the amount of variation.

The present invention will be explained in detail below based on embodiments shown in the drawings.

In this embodiment, the reel shafts 2, 2, 2 of the three reels 1, 1, 1 displaying a plurality of types of symbols are directly connected to the stepping motors 3, 3, 3, respectively. 3, the reels 1, 1,
This structure is basically the same as that disclosed in Japanese Patent Laid-Open No. 56-70779.

When a coin is inserted into the coin slot 7 provided in the main body case 4, the coin acceptance detection means 8 sends a coin acceptance signal P to the stepping motor circuit 9. Next, when the start lever 5 disposed on the front surface of the main body case 4 is rotated, a start signal q is sent to the stepping motor circuit 9 from a means for detecting the operation of the start lever 5, such as a limit switch. The start lever 5 is biased in the return rotation direction by a return spring 10, and the return speed is configured to vary depending on the initial rotation angle of the start lever 5. This return speed is determined by detecting the time difference in which the movable part of the start lever 5 (it is preferable to use a rotating piece that rotates integrally with the lever part) 5a shields the two photocouplers 11a and 11b from light during the return rotation. , is measured by converting this into a speed by the speed command circuit 12. Then, a speed command signal r is sent from the speed command circuit 12 to the stepping motor circuit 9.
will be sent.

The stepping motor circuit 9 is equipped with an input control circuit and a distribution circuit, and receives both the coin acceptance signal p and the start signal q to apply drive pulses S, S, S, and these driving pulses S,
S and S are set to the number of pulses per unit time according to the speed command signal r.

As described above, the stepping motors 3, 3,
3 rotates at a speed determined by the number of pulses per unit time, and drives the reels 1, 1, 1 to rotate at the speed. At this time, it is preferable to configure the rotational speed of the reel 1 to be selected from approximately five levels.

The player can stop the reel 1 corresponding to each stop button 6 by pressing and operating the three stop buttons 6, 6, 6 provided on the front of the main body case 4. That is, by pressing the stop button 6, a stop command signal t is sent to the stepping motor circuit 9, and based on this, the rotation of the stepping motors 3, 3, 3 is stopped.

When the three reels 1, 1, 1 stop, the combination of symbols on these reels 1, 1, 1 is detected and it is determined whether it is a winning game or a losing game, and a predetermined number of coins are awarded for a winning game. The coins are paid out to a coin payout opening 13 provided on the front side of the main body case 4. The above symbol combinations are on each reel 1, 1, 1
The stopping position of the reel 1 can be accurately determined by the count value of the drive pulses that drive the stepping motor 3.

As described above, in this embodiment, the detection means 14 for detecting the speed of the return rotation of the movable part 5a of the start lever 5 is composed of two sets of photocouplers 11a and 11b. The movable part 5 is activated by the voltage and current output according to the speed at which the magnetic field is cut when 5a rotates to return (or at the time of initial rotation).
It can also be configured by means for detecting the speed of a.

Further, in a slot machine equipped with a start button, the detection means 14 can be configured to detect the speed of the movable part.

Furthermore, in a slot machine equipped with either a start lever 5 or a start button, the detection means 14 can be configured to detect the amount of variation in the movable part 5a (for example, the initial rotation angle of the start lever 5). It is.

In this embodiment, as described above, a control device (stepping motor circuit) 9 is provided which controls the number of pulses per unit time for driving the stepping motor 3 based on the detection signal (speed command signal) r of the detection means 14. The control device 9 is configured to change the rotational speed of the reel 1 according to the speed of the movable portion 5a (as described above, the amount of variation may be sufficient), but the control device 9 is as shown in this embodiment. Of course, it is not limited to.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, the present invention can be implemented in a slot machine having two reels 1 or four or more reels.

Since the present invention has the above configuration, the player can enjoy the game by changing the rotational speed of the reels by controlling the start lever (or start button) in each game. Also, as a result, the player will operate the start lever (or start button) in order to select the rotation speed of the reels that is most advantageous to the player's pressing operation of the stop button, but it is necessary to be skilled at such operations. This will provide technical enjoyment.

In addition to the above-mentioned effects, the present invention controls the rotational speed of the reel by controlling the number of pulses per unit time for driving the stepping motor, thereby reducing the complexity of the structure. It also has the effect of being able to keep it to a minimum.
