[0019]

[Table 1]

As shown on the right side of FIG. 5, the code information 54 is displayed in a binary number on the back surface 53 of the reel tape 50, and a black circle mark 55 is provided only at a portion corresponding to the binary number "1". It is printed. As shown in FIG. 5, the mark 55 forming the code information 54 is the surface of the reel tape 50.
Along the center line of the center of the pattern 52 of 51, the upper bits, the intermediate bits, and the lower bits are displayed in order from the right side.

The mark 55 is the back surface of the reel tape 50.
In addition to directly printing on 53, it may be printed on a sticker or the like and later attached to the back surface 53 of the reel tape 50. Further, the mark 55 is not limited to being directly behind each pattern 52 on the front surface 51 of the reel tape 50, and may be displayed at a position slightly deviated. On the other hand, a code information reading means 60 for reading the code information 54 on the back surface 53 of the reel tape 50 is fixed to the base frame 31 of the reel unit 30, as shown in FIGS.

The code information reading means 60 is composed of, for example, an optical sensor, and detects the mark 55 forming the code information 54 by utilizing the reflectance of light. Next, the control circuit of the slot machine 10 will be described with reference to FIG. As shown in FIG. 1, the control circuit of the slot machine 10 is mainly composed of a central controller 70.

On the input side of the central control unit 70, as shown in FIG. 1, a code information reading means 60 is provided as an input / output means (I / I).
O) connected through 80. In addition, the central controller 70
As shown in FIG. 1, each stepping motor 32 is connected to the output side of each of them through a motor drive 90. As shown in FIG. 1, the central control device 70 has symbol development areas 71 to 73 for storing the code information 54 read by the code information reading means 60 for each rotating reel 12 to 14 in the reading order. A random access memory (hereinafter referred to as "RAM") 74, a read-only memory (hereinafter referred to as "ROM") 75 in which a game program is written, and a game program written in this ROM 75 are read out and read out. A central processing unit (hereinafter referred to as "CPU") 76 for controlling the drive of each stepping motor 32 while reading the code information 54 written in each of the symbol development areas 71 to 73 of the RAM 74 according to the game program. ing.

The symbol development areas 71 to 73 of the RAM 74 are
As shown in FIG. 1, three areas equal to the number of rotating reels 12 to 14 are secured. Each pattern development area 71-73
As shown in FIG. 6, a pattern 52 on one reel tape 50
, For example, 21 store positions equal to 21. Next, a slot machine having the above configuration
The operation of 10 will be described with reference to the flowchart shown in FIG.

First, during the rotation of the respective rotary reels 12-14,
As shown in FIG. 7, the process proceeds to step 100 and the reel tape 5
It is determined whether or not the marks 55 forming the code information 54 on the back surface 53 of 0 are detected by the code information reading means 60. This determination is performed by the CPU 76 (FIG. 1) of the central control device 70, and the CPU 76 is proceeding with the processing according to the game program read from the ROM 75.

The detection of the mark 55 is performed for each game, but of course, when the power of the slot machine 10 is turned on,
The rotation reels 12 to 14 may be rotated to detect the mark 55. Further, the detection of the mark 55 is started at the time of starting the stepping motor 32 to speed up the detection of the mark 55, but of course, the detection of the mark 55 is performed after the rotation speed of the stepping motor 32 becomes a constant speed. May be started.

If the mark 55 is detected in the above step 100, as shown in FIG.
Proceed to 101. In this step 101, mark 55 is R
Store in the corresponding symbol development areas 71 to 73 of AM74.
For example, as shown in FIG. 5, the code information reading means 60
If it is located directly behind the "OR" pattern OR,
The code information reading means 60 sends the code information 54 of “110” in binary to the CPU 76 (FIG. 1). CPU
When 76 inputs the code information 54, as shown in FIG.
Hexadecimal "6H" is written in the first store position.

After the above processing is completed, the routine proceeds from step 101 to step 102 as shown in FIG. In this step 102, "1" is added to the previous store position in the symbol development areas 71-73. As a result, for example, the store position advances from the first position to the second position. After the above processing is completed, the process proceeds from step 102 to step 103 as shown in FIG. In step 103, it is determined whether 21 marks 55 have been detected. This is because the number of the symbols 52 on the reel tape 50 of each of the rotating reels 12 to 14 is 21 in total, and it is to determine whether each of the rotating reels 12 to 14 has completed one round. .

In step 103, the mark 55 is 2
When one mark is not detected, as shown in FIG. 7, the process returns to the previous step 100, and every time the mark 55 is detected, the mark 55 is stored at the next store position of the previous store position. . For example, as shown in FIG. 5, if the symbol SE is “7” located in the front of the rotation direction next to the symbol OR of “orange”, the binary number is “001”, so the second store Hexadecimal "1H" is written at the position (FIG. 6).

In this way, when the 21st "star" symbol ST (Fig. 5) is detected and the hexadecimal "4H" is written in the 21st store position (Fig. 6), the process concerned. To finish. In step 100, mark 55
If is not detected, the step 100 is repeated. However, if a prescribed number of drive pulses are sent to the stepping motor 32 and the mark 55 is not detected, it is possible to detect step out of the stepping motor 32.

That is, in this embodiment, the code information 54
In addition, since the binary number "000" is not used, the previous pattern
Step-out can be detected within a range of a dozen degrees from the mark 55 of 52 to the mark 55 of the next pattern 52. Therefore, the mark 55 can also be used as a position signal for detecting out-of-step. On the other hand, in the conventional slot machine, the reference position of the rotating reel is detected and the counter of the stepping motor is reset every one rotation of the stepping motor, so the step-out is detected until the stepping motor makes one rotation. I couldn't do that, and I was delayed by that amount. According to the present embodiment, it is possible to detect out-of-steps early and deal with them.
