Description

[Detailed Description of the Invention] Related. More specifically, the present invention relates to a reel stopping mechanism that randomly determines the combination of symbols on the reels when stopping a plurality of reels of a slot machine.

It is preferable for slot machines to have random combinations of symbols on the reels, and various types of reel stops.
s has been proposed and implemented. However, all of them mechanically determine the stop position of the reel, and utilize the variation in the number of rotations of the reel each time.

Therefore, when the number of times played is small, the combinations of symbols appear to be random, but when played many times, the combinations of symbols become biased due to the peculiarities of the slot machine, and cannot be called random at all.

The present invention is a slot machine (IJ reel stop mechanism) that eliminates the drawback of tilting, and includes (A) a handle signal detection section that detects a signal generated by pulling down the handle; (B) a signal from the handle signal detection section. a random number generation circuit that determines random number information; (0) a symbol position detection unit that creates symbol position information on the rotating reels; (D) a symbol position detector that generates symbol position information on the rotating reels; a comparison calculation unit that reads the combinations and payouts, compares them with symbol position information, and outputs reel stop position information;
and (1'a IJ-Reel stop part that stops the reels with the determined combination of symbols based on the reel stop position information).

Next, an embodiment of the reel stop mechanism of the present invention is shown in Figure iTi'+
However, the present invention is not limited to these embodiments.

A slot machine usually has an appearance as shown in Figure 1, with the handle (1) pulled and three reels (2a),
(2b) and (20) are rotated and the six reels are sequentially stopped by pressing the automatic matach stop buttons (3a), (3b), and (3c), and a predetermined number of medals are ejected according to the combination of symbols. do.

FIG. 2 shows a block diagram of an embodiment of the reel stop mechanism of the present invention.

When the handle (2) is pulled, the switch (4) turns on and emits a signal, but since this signal contains chattering and noise, the waveform is shaped by the waveform shaping section (5) and then sent to the timer (6). It will be done. The switch (4), waveform shaping section (5), and timer (6) are the handle signal detection section (7)
It consists of

The output signal of the timer (6) is input to the latch (9) of the random number generation circuit (8) as a data latch signal. On the other hand, the latch (9) receives a data signal updated at high speed from the counter (Ill), which is always in a free run state due to the free run of the oscillator 11f11.

When the handle signal from the timer 011 (6) is input to the latch (9) to which the data of the free run state is always input, random number information (payout table memo IJ (+31 address fell) is sent from the latch (9) to the comparison calculation unit 02.

The comparison calculation unit u7J reads the combination of symbols and the dividend stored in the address (based on the random number information) from the payout table memory (1:ll) in which the daple of the combination of symbols and the corresponding dividend is stored. .

A mechanism for detecting the position of symbols on the counting reel will be explained based on FIGS. 2 and 6. Figure 3 1 shows the reel (2
aJ , (2b) , (stop disk (141 and a pair of photosens →) disposed on each of the two) (1
5a), (]-5b) and (16a), (1(
ib) is a schematic perspective view of a known pattern position detecting device 6 constructed from the following. The circumference of the disc corresponds to each pattern.

A groove (1η) is provided, and holes corresponding to each pattern are arranged near the center.A reference hole (19) is provided near the center of one of the holes (181 Photosensor (15a), (15b
) is aimed at the hole (+81), and the photosensors (16a), (16t)') are aimed at the reference hole f+91.

When the disk (141) starts to rotate, the photo sensor (15
aJ, (15bJ) A frame pulse signal is generated by the number of frames of the pattern that has passed. This frame pulse signal is sent to the waveform shaping section (2N) of the picture position detection section (a), where the waveform is shaped, and then inputted into the counter (2214).

On the other hand, the reference hole (+91 is the photosensor (16a),
16b), a reference pulse signal is generated, sent to the waveform shaping section (2), shaped into a waveform, and then input to the counter. The counter (support) returns the frame pulse signal to zero each time the reference pulse signal is input.

The output from the counter @ includes picture position information indicating the number of pictures currently passing through the photosensors (15a) and (15b) from the reference picture. This picture finish is sent to the 17+1 comparison operation Φ calculation section.

The comparison operation η section (12+ compares and calculates the symbol combination information randomly determined by the random numbers with the current position information from the symbol position Ft detection section 5) Output.

The reel stop position information is output when a target symbol appears within a predetermined number of frames from the symbol display position after the reels have been rotated a predetermined number of times.

The down counter (to) counts down the input reel stop position information using a count signal for each frame obtained by the photo sensor (15b). The counted down signal is sent to the comparator surface, and when the content reaches zero, the comparator surface sends a stop signal to the solenoid prisoner via a timer, and the reels stop at the position where the target symbol is displayed. urge

A commonly used solenoid type mechanism can be used as the reel stop mechanism.

FIG. 4 shows an example of a solenoid type reel stop mechanism.

As shown in Fig. 4, this type of stop mechanism is composed of a combination of a solenoid prisoner and a link, and when a stop signal is input from the stop part (2Φ) that releases the solenoid prisoner aiJ, the solenoid Click the link (7) with the arrow (A
) direction. Then link (31) becomes link Cl21
Pull the hook in the direction of arrow (B) and tilt the hook east in the direction of arrow (0) to engage the groove 0η of the disk +141 and stop the reel.

As described above, in the present invention, since symbol combinations are determined by random numbers, symbol combinations can be obtained completely based on probability, and the reels can be accurately stopped with that combination.

Therefore, in the long run, dividends can be changed according to the probability,
In the short term, there is a possibility that large payouts can be won in succession, making it fair and increasing the enjoyment of the players.

The reel drive mechanism includes a mechanism that mechanically rotates the reel by pulling down the handle (2), and a mechanism that rotates the reel mechanically by pulling down the handle (2).
A conventionally known drive mechanism, such as a mechanism rotated by a motor, can be employed.

You can also use the reel stop button (3a), (3) to stop the reels.
This can also be done by pressing b) and (3C).

In that case, the signal generated by pressing the stop button is shaped into a waveform by the stop signal unit 0 or the waveform shaping unit 135), and then a stop signal is sent to the comparison calculation unit (121).When the stop signal is input, the comparison calculation is performed. In part tta, unlike the above, it compares whether or not there is a symbol determined by a random number within a predetermined number of frames from the current symbol while waiting for a stop signal to be input, and if that symbol is present, the reels are stopped at that position. Reel stop position information is output to the down counter (c), and if the desired pattern is not found within a predetermined number of frames, predetermined reel stop position information is output to the down counter (5).

Therefore, when a stop button is used, the player's intention can be added, and the game quality can be further improved.
