2. Description of the Related Art Conventionally, when a start switch is operated, rotation of all three rotating reels is started, and when a stop switch is operated, rotation of a rotating reel corresponding to the stop switch is stopped and all three reels are stopped. When the rotation of the rotating reel is stopped, when a predetermined symbol is aligned on an effective pay line, a slot machine is provided in which a prize is won and a predetermined profit is given.

In such a slot machine, when the start switch is operated, a lottery is performed according to the number of inserted medals, and the rotation reel stop control is performed based on the result of the lottery. There is. Specifically, inside the slot machine, a medal passage through which medals inserted from the medal insertion opening flow down is provided. This medal passage communicates with the medal storage portion of the hopper.
A medal return passage branches off from the middle of the medal passage. This medal return passage communicates with the medal return port. Further, in the vicinity of the branch portion between the medal passage and the medal return passage, a medal selecting device for selecting medals,
And a path switching device for switching the path of the medal. Further, a medal sensor for detecting medals and outputting a medal detection signal is provided in the middle of the medal passage and downstream of the medal selecting device and the route switching device. Further, the control device of the slot machine is provided with counting means for counting the number of medals based on the medal detection signal.

When a medal inserted from the medal insertion slot flows down the medal passage, passes through the medal selecting device and the route switching device, and passes the medal sensor, a medal detection signal is output. Then, the number of medals inserted from the medal insertion slot is counted by the counting means performing the counting operation based on the medal detection signal. The medals that have passed through the medal sensor further flow down the medal passage and are stored in the medal storage portion of the hopper.

On the other hand, on the front surface of the slot machine, there is provided a start switch for starting the rotation of the rotary reel. This start switch outputs a start signal when operated. Further, the control device of the slot machine includes a lottery means for performing a lottery and a game control means for controlling a game. In addition, the lottery means acquires a lottery table according to the number of inserted medals when the start signal is input, and performs the lottery. In addition, the game control means starts the rotation of the rotary reel upon the input of the start signal, and based on the lottery result of the lottery means and the rotation position of the rotary reel when the stop switch is operated, the rotary reel. Stop control. Then, when the rotation of all the rotary reels is stopped, if the predetermined symbols are aligned on the effective pay line, it is determined that the prize is won and a predetermined profit is given to the player.

By the way, the lottery table is set so that the winning probability increases as the number of inserted medals increases. Further, the game control means, when the lottery result is a win, performs a stop control of the rotating reels so that the predetermined symbols can be aligned on the effective winning line, while, when the lottery result is lost, a predetermined The rotation reel stop control is performed so that the symbols are not aligned on the effective pay line.

That is, the number of inserted medals and the probability of winning are closely related.
The winning probability is high.

[0008]

However, in the conventional slot machine, there is a slight time lag between the passage of the medal and the passage of the medal sensor until the medal passes through the medal sensor. There was a slight time lag before the operation of the route changer. Therefore, for example, when three medals are continuously inserted from the medal insertion slot and the start switch is operated when the second medal passes the medal sensor, the number of inserted medals is two. As a result, a so-called swallowing phenomenon may occur in which the third medal is stored in the medal storage portion of the hopper despite the progress of the game.

That is, when the start switch is operated when the second medal passes through the medal sensor,
When the start signal output at this time is input,
The lottery means performs the lottery according to the count value “2” of the counting means, and the course switching device switches the course of the medal toward the medal return passage direction. As a result, medals that are about to pass through the course switching device after the start switch is operated will be returned from the medal return opening through the medal return passage.

However, if the third medal is approaching the course switching device at the time of operating the start switch, the third medal has the above-mentioned time lag.
Passing the route switching device. Then, despite passing through the medal sensor and being stored in the medal storage portion of the hopper, the third medal is not counted, and the game is progressed assuming that the number of inserted medal is two. It ends up.

This causes a disadvantage to the player. Therefore, according to the invention of claim 1, when the medal detection signal is input within a predetermined time from the input of the start signal, the number of medals is counted based on the medal detection signal. In addition to adding to the count value of the counting means, if the number of medals is added, the result of the previous lottery is canceled and the count value of the counting means after the number of medals is added An object of the present invention is to provide a slot machine in which so-called medals are prevented from being swallowed by performing re-lottery by performing re-lottery, and lottery is performed according to the number of inserted medals.

[Means for Solving the Problems] (Claim 1) The invention according to claim 1 includes a medal sensor (90) for detecting a medal inserted from a medal insertion slot (51) and outputting a medal detection signal. A counting means (110) for counting the number of medals based on the medal detection signal, a start switch (41) for outputting a start signal by operation, and a count value of the counting means (110) triggered by the input of the start signal. A slot machine (10) provided with a lottery means (160) for performing a lottery, and when a medal detection signal is input within a predetermined time from the input of a start signal, it is input within this predetermined time. The counting means (110) counts the number of medals based on the medal detection signal.
An additional counting means (120) for adding to the count value of
When the number of medals is added by the additional counting means (120), the lottery result of the lottery means (160) is canceled, and the number of medals is added by the additional counting means (120). Counting means (110)
And a re-lottery means (170) for performing a lottery according to the count value of.

That is, the slot machine (10) according to the present invention counts the number of medals based on the medal detection signal when the medal detection signal is input within a predetermined time from the input of the start signal. In addition to adding to the count value of the counting means (110), if the number of medals is added, the result of the previous lottery is canceled and the counting means (110 after adding the number of medals is added. ), The re-lottery is performed according to the count value.

Here, the "medal sensor (90)" detects a medal inserted from the medal insertion slot (51),
This is for outputting a "medal detection signal". That is, inside the slot machine (10), there is a medal passage (5
2) is provided, and a medal sensor (90) is provided in the middle of the medal passage (52). Then, the medals inserted from the medal insertion slot (51) are transferred to the medal passage (52).
When it flows down and passes through the medal sensor (90), a medal detection signal is output.

Further, the medal sensor (90) can be constructed by using, for example, a photo sensor, a proximity sensor, a micro switch or the like. Also,
The "start switch (41)" is for outputting a "start signal" by operation. That is, when the start switch (41) is operated, a start signal is output. Then, triggered by the input of this start signal, for example, the game control means (100) is rotated by the rotating reel (30).
The rotation of the medal is started, the lottery means (160) performs a lottery to determine whether or not the prize is won, or the course switching device (80) switches the course of the medal toward the medal return passage (53).

The "counting means (110)" is for counting the number of medals based on the medal detection signal. That is, when a medal inserted from the medal insertion slot (51) flows down the medal passage (52) and passes the medal sensor (90), a medal detection signal is output. Then, based on this medal detection signal, the counting means (110) performs a counting operation to count the number of medals inserted from the medal insertion opening (51).

The counting means (110) can be formed, for example, by causing a computer constituting the control device (20) to execute a predetermined program. When the medal detection signal is input within a predetermined time from the input of the start signal, the "additional counting means (120)" determines the number of medals based on the medal detection signal input within the predetermined time. It is for counting and adding to the count value of the counting means (110).

That is, in the slot machine (10), there is a slight time lag between the passage of the medal through the route switching device (80) and the passage of the medal sensor (90), and the start signal is output. There is a slight time lag between the start of operation and the operation of the route switching device (80). Therefore, when the medal detection signal is input within a predetermined time from the input of the start signal, the number of medals is counted based on the medal detection signal input within the predetermined time, and the counting means (110) It is this additional counting means (120) that tries to prevent the so-called swallowing of medals by adding to the count value.

Specifically, for example, when the start switch (41) is operated and a start signal is output,
It is assumed that the count value of the counting means (110) is "2". Further, it is assumed that the medal detection signal is input once within a predetermined time from the input of the start signal. Then,
The additional counting means (120) is based on the medal detection signal input within the predetermined time, and the number of medals is "1".
Is counted and added to the count value of the counting means (110). As a result, the count value of the counting means (110) becomes "3".

The "predetermined time" is the time lag from the passage of the medal through the route switching device (80) to the passage of the medal sensor (90), or the route switching device (80) after the start signal is output. Can be appropriately determined in consideration of a time lag until the operation of the. In addition, the additional counting means (120) is, for example,
It can be formed by causing a computer constituting (0) to execute a predetermined program.

The "lottery means (160)" is for carrying out a lottery according to the count value of the counting means (110), triggered by the input of the start signal. In this lottery means (160), the start switch (41) is operated,
When the start signal is output, the lottery is performed when the start signal is input. In addition, this lottery means (160)
Performs a lottery according to the count value of the counting means (110) when the start signal is input.

Specifically, for example, when the start switch (41) is operated and a start signal is output,
It is assumed that the count value of the counting means (110) is "2". Then, the lottery means (160) performs the lottery according to the count value “2” of the counting means (110) when the start signal is input, triggered by the input of the start signal.

The lottery means (160) is, for example,
It can be formed by causing a computer constituting the control device (20) to execute a predetermined program.
Also, the "re-lottery means (170)" is an additional counting means (1
When the number of medals is added by 20), the lottery result of the lottery means (160) is canceled and the number of medals is added by the additional counting means (120). This is for conducting a lottery according to the count value.

The re-lottering means (170) performs the lottery when the number of medals is added by the additional counting means (120). The re-lottery means (170) cancels the lottery result of the lottery means (160) and re-lotters. The re-lottery means (170) performs lottery according to the count value of the count means (110) after the number of medals has been added by the additional count means (120).

Specifically, for example, when the start switch (41) is operated and a start signal is output,
It is assumed that the count value of the counting means (110) is "2". Then, the lottery means (160) performs the lottery according to the count value “2” of the count means (110), triggered by the input of the start signal. Further, it is assumed that the medal detection signal is input once within a predetermined time from the input of the start signal. Then, the additional counting means (120)

0) Add to the count value. As a result, the count value of the counting means (110) becomes "3". In such a case, the re-lottery means (170) cancels the lottery result of the lottery means (160), and the lottery according to the count value “3” of the counting means (110) after the number of medals is added. To do.

Further, the re-lottering means (170) can be formed, for example, by causing a computer constituting the control device (20) to execute a predetermined program. Thus, when the medal detection signal is input within a predetermined time from the start signal input, the number of medals is counted based on the medal detection signal and added to the count value of the counting means (110). At the same time, when the number of medals is added, the result of the previous lottery is canceled, and re-lottery is performed according to the count value of the counting means (110) after the number of medals is added. Thus, it is possible to prevent the so-called medals from being swallowed, and to carry out a lottery according to the number of inserted medals, which in turn can prevent the player from being disadvantaged.

Furthermore, the additional count means (120) and the re-lottery means (170) can be realized by software. Therefore, it is possible to prevent the so-called swallowing of medals and perform a lottery according to the number of inserted medals without taking a hardware measure such as adding a sensor. (Claim 2) In addition to the features of the invention of claim 1, a second upper limit is set for the count value of the counting means (110), and the counting means (11)
When the count value of 0) has reached a predetermined upper limit value, even if the medal detection signal is input within a predetermined time from the input of the start signal, the additional counting means (120)
Is characterized in that the number of medals is not added.

That is, in the slot machine (10) according to the present invention, when the count value of the counting means (110) reaches the upper limit value, the medal detection signal is input within a predetermined time from the input of the start signal. Even if there is, the number of medals is not added so that the re-lottery is not performed. For example, the “upper limit” can be set to “3”. That is, it is possible to insert up to three medals in one game. In this case, if three or more medals are inserted, the count value of the counting means (110) reaches the upper limit value, so that the lottery will be conducted under the best condition for the player.
Therefore, it is not necessary to perform the re-lottery.

In this way, when the count value of the counting means (110) has reached the upper limit value, the number of medals is not added and the re-lottery is not performed, thereby controlling It is possible to reduce the load on the device (20) and smooth the game processing. (Claim 3) In addition to the features of the invention according to claim 1 or 2, the slot machine (10) is provided with a plurality of slots provided corresponding to respective count values of the counting means (110). The lottery means (160) is provided with the lottery means (160), and the lottery means (160) obtains a lottery table (150) corresponding to the count value of the count means (110) when a start signal is input to perform a lottery. The re-lottery means (170) acquires the lottery table (150) according to the count value of the counting means (110) after the number of medals has been added by the additional counting means (120), and conducts the lottery. And

That is, the slot machine (10) according to the present invention obtains the lottery table (150) corresponding to the count value of the counting means (110) when the start signal is input in the previous lottery. In addition to performing the lottery, in the re-lottery, the lottery table (15) corresponding to the count value of the counting means (110) after the number of medals is added

(Medal selection device 70) Medal selection device 70
Is for selecting medals, and is provided in the vicinity of a branch portion between the medal passage 52 and the medal return passage 53, as shown in FIG. All the medals inserted from the medal insertion slot 51 are sorted by the medal sorting device 70. Then, medals conforming to the standard can pass through the medal selecting device 70 and further flow down the medal passage 52.
The course is changed by the flow, flows down the medal return passage 53, and is returned from the medal return port 55.

(Route switching device 80) The route switching device 80 is for switching the route of medals. As shown in FIG. 3, the route switching device 80 includes a medal selecting device 70, a medal passage 52 and a medal returning passage 53. It is provided near the branch. The path switching device 80 includes a path switching member for switching the path of the medal and a solenoid for moving the path switching member. Further, the solenoid is controlled by the route switching means 180 included in the control device 20.

When the medal can be accepted, the course switching device 80 changes the course of the medal to the medal passage 52.
On the other hand, when the medal cannot be accepted, the course of the medal is set to the medal return passage 53 direction. As a result, the medal inserted from the medal insertion slot 51 can pass through the route switching device 80 and further flow down the medal passage 52 when the medal can be accepted, but the medal cannot be accepted. In this case, the route is changed by the route switching device 80, flows down the medal return passage 52, and is returned from the medal return port 55.

[Medal sensor 90] Medal sensor 90
Detects the medals inserted from the medal insertion slot 51,
This is for outputting a medal detection signal. As shown in FIG. 3, the medal sensor 90 is provided in the middle of the medal passage 52 and downstream of the medal selecting device 70 and the route switching device 80.

When a medal inserted from the medal insertion port 51 flows down the medal passage 52, passes through the medal selecting device 70 and the route switching device 80, and passes the medal sensor 90, a medal detection signal is output. Is done. The medals that have passed through the medal sensor 90 further flow down the medal passage 52 and are stored in the medal storage portion of the hopper 60.

Specifically, the medal sensor 90 is constructed by using a photo sensor having a light emitting portion and a light receiving portion. Also, this medal sensor 90 is normally
The light emitted from the light emitting unit reaches the light receiving unit, and when the medal inserted from the medal insertion port 51 flows down the medal passage 52 and passes through the medal sensor 90, the light is emitted from the light emitting unit. The emitted light does not reach the light receiving part.

When the light emitted from the light emitting portion reaches the light receiving portion, the medal sensor 90 keeps outputting the Hi level signal from the output terminal of the photo sensor and at the same time outputs the light emitted from the light emitting portion. When the light does not reach the light receiving portion, a Lo level signal is output from the output terminal of the photo sensor. That is, the Lo level signal output from the output terminal of the photo sensor is
It is used as a medal detection signal.

Further, the medal sensor 90 is composed of two photo sensors arranged in parallel along the longitudinal direction of the medal passage 52. The photo sensor provided on the upstream side of the medal passage 52 is the first sensor 91, and the photo sensor provided on the downstream side of the medal passage 52 is the second sensor 92. In the slot machine 10 according to the present embodiment, the medal sensor 90 is composed of two photo sensors to detect the advancing direction of the medal and prevent illegal acts such as pulling back the inserted medal. I am trying.

That is, if the first sensor 91 first detects a medal and then the second sensor 92 detects a medal, the traveling direction of the medal is normal, but the second sensor 92 first detects the medal. Then, if the first sensor 91 detects the medal after that, the traveling direction of the medal is abnormal. Then, in the slot machine 10 according to the present embodiment, when there is an abnormality in the moving direction of the medal, by taking measures such as stopping the progress of the game, an illegal act such as pulling back the inserted medal is performed. I try not to be discouraged.

(Game control means 100) The game control means 100 is
It is for controlling the game. Hereinafter, a game in the slot machine 10 will be described. When you insert a medal,
The number of winning lines according to the number of inserted medals becomes effective. Here, the insertion of medals includes both insertion of medals from the medal insertion opening 51 and insertion of medals by operating the bet switch 43. When the start switch 41 is operated under the condition that a medal is inserted, the lottery means 160 performs a lottery, and all three rotating reels.
30 rotations start. After that, when one of the three stop switches 42 is operated, the stop switch
The rotation of the rotary reel 30 corresponding to 42 is stopped. And
After operating all three stop switches 42, 3
The rotation of all the rotating reels 30 is stopped. At this time,
When the predetermined symbols are lined up on the effective pay line, the prize is won. Then, the number of medals according to the winning mode is credited or paid out from the medal payout port 54.
In addition, instead of paying out medals, or in addition to paying out medals, a predetermined profit may be given to the player.

The stop control of the rotary reel 30 is performed as follows. First, one stop table is selected from a plurality of stop tables based on the lottery result. Next, the number of sliding symbols of the rotary reel 30 is determined from the selected one stop table and the rotational position of the rotary reel 30 when the stop switch 42 is operated.
At this time, if the number of sliding pieces is determined to be 0, the rotation of the rotary reel 30 is immediately stopped. If the number of sliding frames is determined to be 1, the rotating reel 30 rotates by one frame, and the rotation of the rotating reel 30 stops there. If the number of sliding pieces is determined to be 2, the rotating reel 30 is rotated by two pieces, and the rotation of the rotating reel 30 is stopped there. Also, if the number of sliding pieces is determined to be 3, the rotating reel 30 for only three pieces
Rotates, and the rotation of the rotating reel 30 stops there. If the number of sliding pieces is determined to be 4, the rotating reel 30 is rotated by four frames, and the rotation of the rotating reel 30 is stopped there.

The stop table is a table in which the number of sliding frames of the rotary reel 30 is predetermined according to the rotational position of the rotary reel 30 when the stop switch 42 is operated. A plurality of stop tables are provided for each lottery result. Further, the stop control of the rotating reel 30 described above,
It is called "table control" because it uses a stop table.

The stop control of the rotating reel 30 is not limited to this table control, and may be control called "program control", for example. In the program control, first, a flag corresponding to the lottery result is set. Next, when the stop switch 42 is operated, the rotation of the rotary reel 30 is immediately stopped, one frame is slid and then stopped, or two frames are slid and then stopped based on this flag. A judgment is made as to whether to stop after sliding one frame or to stop after sliding four frames. Then, if it is determined to stop immediately, the rotation of the rotary reel 30 immediately stops. If it is determined that the slide reel 1 should be slid and then stopped, the rotary reel 30 is rotated by one frame, and the rotation of the rotary reel 30 is stopped there. Further, if it is determined that the two reels are slid and then stopped, the rotary reel 30 rotates by two frames, and the rotation of the rotary reel 30 stops there. Further, if it is determined that the sliding reel 3 should be slid and then stopped, the rotating reel 30 is rotated by 3 frames, and the rotation of the rotating reel 30 is stopped there.
In addition, if it is judged that it will stop after sliding 4 frames,
The rotating reel 30 rotates for four frames, and the rotating reel there.
The rotation of 30 stops.

(Counting means 110) The counting means 110 is
This is for counting the number of medals based on the medal detection signal. When a medal inserted from the medal insertion opening 51 flows down the medal passage 52, passes through the medal selecting device 70 and the route switching device 80, and passes the medal sensor 90, a medal detection signal is output. Then, based on this medal detection signal, the counting means 110 performs a counting operation, whereby the number of medals inserted from the medal insertion slot 51 is counted.

A predetermined upper limit value is set for the count value of the counting means 110. In the slot machine 10 according to the present embodiment, the upper limit value of the count value of the counting means 110 is set to “3”. That is, the number of inserted medals is up to 3. When the count value of the counting means 110 reaches “3”, the medals inserted after that from the medal insertion slot 51 are counted by the stored medal counting means 190. That is, when four or more medals are inserted from the medal insertion slot 51, the fourth and subsequent medals are counted by the stored medal counting means 190 as stored medals.

(Additional Counting Means 120) When the medal detection signal is input within a predetermined time from the input of the start signal, the additional counting means 120 is based on the medal detection signal input within the predetermined time. Is for counting and adding to the count value of the counting means 110.

That is, there is a slight time lag between the passage of the medal passing through the route switching device 80 and the medal sensor 90, and the period between the output of the start signal and the activation of the route switching device 80. There is also a slight time lag. Therefore, when the medal detection signal is input within a predetermined time from the start signal input, the number of medals is counted based on the medal detection signal input within the predetermined time, and the count value of the counting means 110 is counted. It is this additional counting means 120 that attempts to prevent the so-called swallowing of medals by adding to.

Specifically, for example, it is assumed that the start switch 41 is operated when three medals are continuously inserted from the medal insertion slot 51 and the second medal passes the medal sensor. Then, when the start signal is output, the count value of the counting means 110 is "2". Also, within 3 hours after the start signal is input,
It is assumed that the medal detection signal is input as the second medal passes through the medal sensor 90. Then, the additional counting means 120 makes the number "1" of medals based on the medal detection signal input within the predetermined time.
Is counted and added to the count value of the counting means 110. As a result, the count value of the counting means 110 becomes "3".

The "predetermined time" is the time lag from the passage of the medal through the passage switching device 80 to the passage of the medal sensor 90, or the passage of the medal by the passage switching device 80 after the start switch 41 is operated. It can be appropriately determined in consideration of a time lag before switching. Specifically, the “predetermined time” is, for example, 10
It can be defined between 0 milliseconds and 300 milliseconds.
In the slot machine 10 according to the present embodiment, this is 80 on average from the time the start switch 41 is operated until the course switching device 80 switches the course of the medal.
This is because it takes about milliseconds.

Further, when the count value of the counting means 110 has reached a predetermined upper limit value, the additional counting means 120 receives a medal detection signal within a predetermined time after the start signal is input. It is formed so that the number of medals is not added. (Random Number Generating Unit 130) The random number generating unit 130 stores random numbers for lottery within a predetermined range (for example, 0 to 1638 in decimal).
3) It is for generating.

The random number generating means 130 can be composed of, for example, an oscillating circuit and a counter circuit which counts the clock signal generated by the oscillating circuit (so-called hard random number). In addition, this random number generation means 130
Can also be configured by means for generating a random number by the average sampling method, or means for generating a random number by adding prime numbers. Further, these means can be configured, for example, by causing the CPU of the control device 20 to execute a predetermined program (so-called soft random number).

(Random Number Acquisition Unit 140) The random number acquisition unit 140 is
This is for obtaining the random number generated by the random number generation means 130 at a predetermined trigger. The random number acquisition unit 140 acquires the random number generated by the random number generation unit 130 when the start signal is input.

Since the random number generating means 130 is composed of a counter circuit or the like, the numerical values generated by the random number generating means 130 are not strictly random numbers. However, since the timing at which the start switch 41 is operated is considered to be random, the numerical value extracted by the random number acquisition means 140 can be treated substantially as a random number.

(Lottery table 150) The lottery table 150 is
For the entire range of random numbers generated by the random number generation means 130,
Whether or not to win is determined in advance at a predetermined ratio. This lottery table 150 has a predetermined number of random numbers in the entire range generated by the random number generation means 130, which are to be special game win, small win win, re-game win, or lose. It is defined as a percentage.

A plurality of lottery tables 150 are provided corresponding to the count values of the counting means 110. That is, a plurality of the lottery tables 150 are provided according to the number of inserted medals. Further, the lottery table 150 is set such that the winning probability increases as the count value of the counting means 110 increases.

Specifically, a one-sheet loading lottery table 151 is provided corresponding to the count value "1" of the counting means 110, and the count value "2" of the counting means 110.
In response to the above, a two-sheet loading lottery table 152 is provided, and a three-sheet loading lottery table 153 is provided corresponding to the count value “3” of the counting means 110. Further, the lottery table 152 for inserting two pieces is set to have a higher winning probability than the lottery table 151 for inserting one piece, and the lottery table 153 for inserting three pieces is the lottery table 152 for inserting two pieces. The winning probability is set higher than.

(Lottery means 160) The lottery means 160 is for carrying out lottery according to the count value of the counting means 110, triggered by the input of the start signal. This lottery means
160 is the counting means 110 when the start signal is input.
The lottery table 150 corresponding to the count value of is acquired. Then, the lottery table 150 and the random number obtained by the random number acquisition means 140 upon the input of the start signal are used to perform the lottery.

Specifically, for example, the start switch 41
It is assumed that the count value of the counting means 110 is "2" when is operated and a start signal is output. Then, the lottery means 160 acquires the lottery table 152 for inserting two cards. Then, the lottery table 152 for inserting two cards is compared with the random number acquired by the random number acquisition means 140 when the start signal is input to determine the winning.

(Re-lottery means 170) The re-lottery means 170 cancels the lottery result of the lottery means 160 when the number of medals is added by the additional counting means 120,
This is for performing lottery according to the count value of the counting means 110 after the number of medals has been added by the additional counting means 120.

This re-lottery means 170 is an additional counting means 1
If the number of medals is added by 20, the lottery will be conducted. Further, the re-lottery means 170 cancels the lottery result of the lottery means 160 and re-lotters. Further, the re-lottery means 170 performs lottery according to the count value of the count means 110 after the number of medals has been added by the additional count means 120.

Specifically, for example, the start switch 41
It is assumed that the count value of the counting means 110 is "2" when is operated and a start signal is output. Then, the lottery means 160 uses the lottery table 152 for inserting two cards.
To get. And this lottery table for loading 2 cards 15
The winning is determined by comparing 2 with the random number acquired by the random number acquisition means 140 when the start signal is input. Here, it is assumed that the medal detection signal is input once within a predetermined time from the input of the start signal. Then,
The additional counting means 120 counts the number of medals “1” based on the medal detection signal input within this predetermined time and adds it to the count value of the counting means 110. As a result, the count value of the counting means 110 becomes "3". Then, the re-lottery means 170 cancels the lottery result of the lottery means 160 and acquires the three-piece insertion lottery table 153. Then, the lottery table 153 for throwing in three pieces and the random number obtained by the random number obtaining means 140 upon the input of the start signal are used to perform the lottery.

(Route switching means 180) The route switching means 180 is
This is for switching the path of the medal by driving the solenoid of the path switching device 80 and moving the path switching member. When the medals can be accepted, the course switching means 180 sets the course of the medals to the direction of the medal passage 52, and when the medals cannot be accepted, the course of the medals is set to the direction of the medal return passage 53.

Specifically, in the slot machine 10 according to the present embodiment, it is impossible to accept medals when the start signal is input. Therefore, the route switching means 18
0 is triggered by the input of the start signal, and the course switching device 8
By driving the solenoid of 0, the course of the medal is switched from the direction of the medal passage 52 to the direction of the medal return passage 53.

Further, the slot machine according to the present embodiment
In 10, when the rotation of all the three rotating reels 30 is stopped, it is determined whether or not there is a prize. In the case of a prize, the payout of medals or the credit is performed. The medals cannot be accepted until these processes are finished, but when these processes are finished, the medals can be accepted. Then, when the medals can be accepted, the route switching means 180 drives the solenoid of the route switching device 80 to switch the route of the medals from the medal return passage 53 direction to the medal passage 52 direction.

Furthermore, the slot machine according to the present embodiment
In 10, the number of inserted medals is up to 3, and the number of stored medals is up to 50. Therefore, the count value of the counting means 110 reaches “3”,
Moreover, the count value of the stored medal counting means 190 is "50".
When it reaches, the path switching means 180 drives the solenoid of the path switching device 80 to move the medal path to the medal path 52.
The direction is switched to the medal return passage 53 direction.

(Stored medal counting means 190) The stored medal counting means 190 is for counting the number of stored medals. In the slot machine 10 according to the present embodiment, the number of inserted medals is up to 3. Therefore, when four or more medals are inserted from the medal insertion slot 51, the fourth and subsequent medals are counted by the accumulated medal counting means 190 as accumulated medals.

Further, the slot machine according to the present embodiment
In 10, the number of inserted medals is up to 3, and the number of stored medals is up to 50. Therefore, the count value of the counting means 110 reaches “3”,
Moreover, the count value of the stored medal counting means 190 is "50".
When the number reaches, the medals inserted from the medal insertion slot 51 thereafter are returned from the medal return slot 55.

Further, the slot machine according to the present embodiment
In 10, the credit may be given instead of paying out the medals, and in this case, the accumulated medal counting means 190,
The number of stored medals is added only for the amount of credits. Further, in the slot machine 10 according to the present embodiment, by operating the bet switch, it is possible to reduce the number of stored medals and replace with the insertion of medals. In this case, the stored medal counting means 190 inserts medals. The number of stored medals is subtracted by the amount replaced with.

(Operation of Slot Machine 10) The operation of the slot machine 10 according to the present embodiment will be described with reference to the flow chart shown in FIG. When the start switch 41 is operated in step 100, step 10
At 1, the start signal is output. Then, the process proceeds to step 102.

At step 102, the random number acquisition means 140 acquires a random number upon the input of the start signal. Then, the process proceeds to step 103. In step 103, the lottery means 160 acquires the lottery table 150 corresponding to the count value of the count means 110 when the start signal is input. That is, if the count value of the counting means 110 when the start signal is input is “M”, the lottery means 160 acquires the lottery table for inserting M sheets. Then, the process proceeds to step 104.

At step 104, the lottery means 160
However, lottery is performed using the random number acquired in step 102 and the lottery table 150 acquired in step 103. Then, the process proceeds to step 105. In step 105, it is determined whether or not the number of inserted medals is three. That is, it is determined whether the count value of the counting means 110 has reached a predetermined upper limit value. Then, if it is determined that the number of inserted medals is 3, the re-lottery is not performed and the lottery process is ended. On the other hand, if it is determined that the number of inserted medals is not 3,
Go to step 106.

At step 106, waiting for elapse of a predetermined time is performed. That is, the waiting for the elapse of the predetermined time is for checking the presence or absence of the medal detection signal after the input of the start signal. Then, the process proceeds to step 107. In step 107, it is judged whether or not the medal detection signal is input within a predetermined time from the input of the start signal. If it is determined that the medal detection signal is input within the predetermined time from the input of the start signal, the process proceeds to step 108. On the other hand, if it is determined that the medal detection signal has not been input within the predetermined time from the input of the start signal, the re-lottery is not performed and the lottery process ends.

In step 108, the additional counting means 120 counts the number of medals based on the medal detection signal input within the predetermined time, and the counting means 110
Add to the count value of. Then, the process proceeds to step 109. In step 109, the re-lottery means 170 cancels the lottery result of the lottery means 160. Then, the process proceeds to step 110.

In step 110, re-lottery means 170
However, the lottery table 150 corresponding to the count value of the counting means 110 after the number of medals has been added by the additional counting means 120 is acquired. That is, the re-lottery means 170
If the count value of the counting means 110 after the number of medals has been added by the additional counting means 120 is “N”, the lottery table for inserting N coins is acquired. And
Go to step 111.

In step 111, re-lottery means 170
However, lottery is performed using the random number acquired in step 102 and the lottery table 150 acquired in step 110. Then, the lottery process ends. As described above, the slot machine 10 according to the present embodiment counts the number of medals based on the medal detection signal when the medal detection signal is input within a predetermined time from the input of the start signal, In addition to adding to the count value of the counting means 110, if the number of medals is added, the result of the previous lottery is canceled and the count value of the counting means 110 after the number of medals is added According to this, the re-lottery is carried out in accordance with this, so that it is possible to prevent so-called swallowing of medals, and to carry out the lottery according to the number of inserted medals, so that the player is not disadvantaged. You can do it.

Furthermore, the additional count means 120 and the re-lottery means 170 can be realized by software. Therefore, it is possible to prevent the so-called swallowing of medals and perform a lottery according to the number of inserted medals without taking a hardware measure such as adding a sensor. Further, in the slot machine 10 according to the present embodiment, when the count value of the counting means 110 reaches the upper limit value, even if the medal detection signal is input within a predetermined time from the input of the start signal, the medal is detected. By not adding the number of, the re-lottery is also not performed,
As a result, the burden on the control device 20 is reduced and the game process is facilitated.

Further, the slot machine according to the present embodiment
In 10 in the previous lottery, the lottery table 150 corresponding to the count value of the counting means 110 when the start signal was input is obtained and the lottery is performed, and in the re-lottery, the number of medals is added. The lottery table 150 corresponding to the count value of the subsequent counting means 110 is re-acquired to perform the lottery, whereby the lottery according to the number of inserted medals is appropriately and surely performed. Of.

The slot machine according to the present embodiment
Although 10 uses the same random number that was acquired when the start signal was input in both the previous lottery and the re-lottery, the random number may be re-acquired in the re-lottery. Specifically, the lottery means 160 is the random number acquisition means 1
40 performs a lottery using the random number acquired upon the input of the start signal, and the re-lottery means 170 acquires upon the input of the medal detection signal which is within the predetermined time from the input of the start signal by the random number acquisition means 140.
