The system includes a winning device 14 and a ball outlet 15 provided below the big winning device 14. In the figure, reference numeral 12 denotes a nail implanted in the game board 3.

FIG. 2 is a perspective view illustrating the drum-type display device 10 for gaming machines according to the first embodiment. 3, 4, and 5 are a front view, a top view, and a rotary shaft sectional view of the drum-type display device 10 for the gaming machine according to the first embodiment. The drum-type display device 10 for gaming machines according to the first embodiment includes a drum stay 20 provided with left, middle, and right stay plate portions 20L, 20C, and 20R, and left, middle, and right stay plate portions. Left, middle, and right drum stepping motors (hereinafter referred to as drum motors) 30L, 30C, and 30R fixed to 20L, 20C, and 20R, and the left attached to the output shaft 30La of the left drum motor 30L The drum 40L, the middle drum 40C that is pivotally attached to the output shaft 30Ca of the middle drum motor 30C, the right drum 40R that is pivotally attached to the output shaft 30Ra of the right drum motor 30R, and the stay plate portions 20L, 20C, The main part is composed of left, middle and right display backlights 50L, 50C and 50R fixed to 20R so as to be inside drums 40L, 40C and 40R.

The drum motors 30L, 30C, and 30R employ well-known stepping motors (for example, stepping motors disclosed in Japanese Patent Laid-Open Nos. 4001-58026 and 4004-254974), and each drum 40L. , 40C, 40R are respectively incorporated with left, middle, and right drum reference position detection sensors 60L, 60C, 60R (see FIG. 6). Each drum 40L, 40C, 40R is provided with a rotation reference position, and each drum reference position detection sensor 60L, 60C, 60R corresponds to this rotation reference position while each drum 40L, 40C, 40R rotates once. Is detected and a detection signal is output.

The drum motors 30L, 30C, 30R are fixed to the stay plate portions 20L, 20C, 20R so that the output shafts 30La, 30Ca, 30Ra are in a straight line. As shown in FIG. 4, this straight line is inclined by an inclination angle θ with respect to the display window 10a in a horizontal plane perpendicular to the vertical plane including the display window 10a. It is set to coincide with the central axis.

As shown in FIG. 5, each of the drums 40L, 40C, and 40R has a truncated cone shape in which the left end surface is opened and the right end surface is closed, and the left and right widths are set to be substantially the same width. The outer peripheral surface is set to have substantially the same inclination angle θ (see FIG. 4). In addition, the radius of the right end surface of the left drum 40L is set to substantially match the radius of the left end surface of the middle drum 40C, and the radius of the right end surface of the middle drum 40C substantially matches the radius of the left end surface of the right drum 40R. Is set to The drums 40L, 40C, and 40R are arranged so as to be respectively attached to the output shafts 30La, 30Ca, and 30Ra of the drum motors 30L, 30C, and 30R at the center position of the right end surface wall that is the center of the rotational moment. . For this reason, in the arrangement state, the outer peripheral surfaces of the respective drums 40L, 40C, 40R are substantially flush with the same inclination angle θ, and form a large truncated cone as a whole. Now, the bottom surface is the right end surface of the right drum 40R, the central axis is the rotation axis of each of the drums 40L, 40C, 40R (output shafts 30La, 30Ca, 30Ra), and the half apex angle is a virtual inclination angle θ (see FIG. 4). Assuming a right cone, the outer peripheral surfaces of the left, middle, and right drums 40L, 40C, and 40R coincide with the outer peripheral surface of this virtual right cone.

A straight line formed by the output shafts 30La, 30Ca, and 30Ra of the drum motors 30L, 30C, and 30R described above coincides with the central axis of the virtual right cone, and the straight line includes the display window 10a. Since each of the drums 40L, 40C, and 40R is inclined by an inclination angle θ with respect to the display window 10a in a horizontal plane that is perpendicular to the plane, as shown in FIG. Are arranged so that the distance from the display window 10a is equal to each other. This distance is set to a short distance so that the symbols arranged on the outer peripheral surfaces of the respective drums 40L, 40C, 40R can be seen from the display window 10a.

As can be seen in part from FIG. 2, there are 14 symbols “1, 2, 3, 4, 5, 6, 7” (including “.” In the symbol, and so on) on the outer peripheral surface of the left drum 40L. Arranged in this order, 16 symbols “1, 2, 3, 7, 4, 5, 6, 7” are arranged in this order on the outer circumferential surface of the middle drum 40C, and 18 symbols are arranged on the outer circumferential surface of the right drum 40R. The symbols “1, 2, 7, 3, 4, 7, 5, 6, 7” are arranged in this order. Since the radius of the outer peripheral surface becomes longer in the order of the left, middle, and right drums 40L, 40C, and 40R, the middle drum 40C has two more than the left drum 40L by making the size of the symbols substantially the same. The right drum 40R has four more symbols than the left drum 40L.

Display backlights 50L, 50C, and 50R are arranged inside the respective drums 40L, 40C, and 40R at positions corresponding to the display windows 10a. The display backlights 50L, 50C, and 50R are fixed to the left, middle, and right stay plate portions 20L, 20C, and 20R of the drum stay 20, respectively.

The drum-type display device 10 for gaming machines can display symbols in 3 rows and 3 columns through the display window 10a, perform reach production using the symbols, etc., according to the winning of the ball to the start winning device 13 When an internal lottery for a special figure (special symbol) is executed, a special figure composed of three-digit Arabic numerals determined by the lottery result is displayed. The drum-type display device 10 for gaming machines simultaneously starts rotation of the drums 40L, 40C, and 40R by the drum motors 30L, 30C, and 30R, and after a predetermined time elapses, the drums 40L and 40C are sequentially left, middle, and right. , 40R is controlled to stop. However, when the three drum motors 30L, 30C, and 30R are rotated at the same angular velocity, the radius increases in the order of the left drum 40L, the middle drum 40C, and the right drum 40R. Since the fluctuation speed of the symbol passing through the speed increases, the rotation speed of the middle drum motor 30C is made slower than the rotation speed of the left drum motor 30L, and the right drum compared to the rotation speed of the middle drum motor 30C. By making the rotational speed of the motor 30R slow, control is performed so that the three rows of symbols appear to fluctuate at the same speed. Each of the left symbol, middle symbol and right symbol of the drum-type display device 10 for gaming machines is scrolled vertically simultaneously with the start of symbol variation, and is stopped and displayed after a predetermined time has elapsed. The player can see 3 × 3 = 9 symbols for each of the drums 40L, 40C, and 40R through the display window 10a, and it is the same as any one of the total of 5 lines of upper, middle, lower, and two diagonal lines. If three numbers line up, it will be a big hit.

Note that if three odd numbers are arranged, it will be a big win in the probability variation pattern, and if three even numbers are arranged, it will be a big hit in the non-probability variation symbol. In the present embodiment, two “7” symbols and one other numeric symbol are arranged on the middle drum, so that when the “7” symbol of the left drum is stopped and displayed on the display window 10a, other numeric symbols are displayed. Compared to the above, the player has the impression that it is likely to develop into a so-called reach, and the right drum has three “7” symbols and one other numeric symbol, so the “7” symbol This will give players the impression that they are more likely to win big hits than when they reach other numbers.

Returning to FIG. 1, the passing gate 11 is a gate without a prize ball, and when a ball is passed through the passing gate 11, for example, a normal symbol (ordinary drawing) is drawn with a probability of 127/128 and won. Then, the start winning device 13 that is an electric chew opens and closes the movable blade.

The start winning device 13 is a variable winning device called a so-called electric chew having a pair of movable blades in the opening. The start winning device 13 detects the passing of the ball to the passing gate 11 and, for example, a normal lottery is performed with a probability of 127/128. One opening time of the movable blade is, for example, 0.5 seconds in normal time, and, for example, 1.8 seconds × 3 times at the time of probability change and short time. As can be seen from the position of the nail 12 shown in FIG. 1, it is possible to win a ball to the start winning device 13 regardless of whether the movable blade is opened or closed.

The big winning device 14 is a variable winning device called a so-called attacker, and is composed of an opening and a lid member, and exhibits a closed state and an open state of the opening as the lid member moves.

FIG. 6 is a circuit block diagram of the gaming machine 1. The gaming machine 1 includes a main control board 100, an amplifier / speaker 102 including speakers 4a and 4b, a decorative lamp 103 and a sub control board 101 for controlling the drum control board 104, and left, middle and right drums. The detection signals from the reference position detection sensors 60L, 60C and 60R are input, and the left, middle and right drum motors 30L, 30C and 30R and the left, middle and right drum backlights 50L, 50C and 50R are turned on. A drum control board 104 for driving control, a payout control board 107 for controlling the payout apparatus 108 and the fire control board 109, a fire control board 109 for controlling the firement apparatus 110, and a gate passage detector 111 provided alongside the passage gate 11. And a start winning detector 113 provided in the start winning device 13 and a large winning detector 114 provided in the large winning device 14. An electric chew solenoid 115 that opens and closes the movable blades of the start winning device 13 that is an electric chew, a large winning solenoid 116 that opens and closes the large winning device 14, and a power supply circuit unit 117 that supplies a predetermined voltage to each substrate. It is configured.

The main control board 100 includes a main circuit 120. The main circuit 120 includes a CPU (Central Processing Unit) 121, a program storage ROM (Read Only Memory) 122, a RAM to which a work area, various counters, and the like are allocated. (Random Access Memory) 123, an input / output (I / O) 124 that is an input / output interface, and the like.

In addition, although it is common for each other board | substrate to comprise CPU and memory separately, it is abbreviate | omitting in FIG.

The sub-control board 101 causes the amplifier / speaker 102 including the speakers 4a and 4b to output sound according to the sound control signal input from the main circuit 120. The sub-control board 101 controls lighting / extinguishing of the decorative lamps 103 according to the lamp control signal input from the main circuit 120. Further, the sub control board 101 outputs a symbol variation signal (drum rotation control signal) input from the main circuit 120 to the drum control board 104.

The drum control board 104 controls each of the left, middle, and right drums 40L, 40C, and 40R according to the symbol variation signal (drum rotation control signal) input from the main circuit 120 via the sub control board 101. Execute the process. Specifically, the drum control board 104 drives and controls the left, middle, and right drum motors 30L, 30C, and 30R. In the first embodiment, three drum motors 30L, 30C, and 30R are provided to rotate the three drums 40L, 40C, and 40R in total, and each drum 40L, 40C, and 40R and each drum are provided. The motors 30L, 30C, and 30R are controlled on a one-to-one basis. Each drum 40L, 40C, 40R is provided with a rotation reference position, and each drum reference position detection sensor 60L, 60C, 60R corresponds to this rotation reference position while each drum 40L, 40C, 40R rotates once. Since the detection signal is transmitted to the drum control board 104, the drum control board 104 rotates the current drums 40L, 40C, and 40R based on the number of steps rotated after receiving the detection signal. The position is specified. Further, the drum control board 104 grasps all the relationships between the positions of the symbols of the respective drums 40L, 40C, and 40R and the number of steps from the rotation reference position, so that the symbol variation signal input from the main circuit 120 is displayed. Accordingly, the drum motors 30L, 30C, and 30R are driven and controlled, and desired change display and stop display can be performed.

The payout control board 107 controls the payout device 108 in accordance with a prize ball payout signal input from the main circuit 120. As a result, a predetermined number of prize balls are paid out to the player. Further, the payout control board 107 outputs a fire control signal input from the main circuit 120 to the fire control board 109.

The launch control board 109 activates the launch device 110 provided corresponding to the launch handle 6 in response to the player operating the launch handle 6. Depending on the amount of operation of the firing handle 6, it is possible to adjust the ball launching strength (ball flight distance).

FIG. 7 is a flowchart showing drum rotation processing (design variation processing) by the drum control board 104.

Next, the operation of the drum-type display device 10 for gaming machines according to the first embodiment configured as described above will be described together with the operation of the gaming machine 1 with reference to FIGS.

After the power to the gaming machine 1 is turned on, the balls prepared in the ball supply tray 5 are fired toward the game board 3 by the launching device 110 including the firing handle 6. The ball that has reached the game board 3 flows down on the board surface of the game board 3.

When the ball flowing down on the board surface of the game board 3 passes through the passage gate 11, the gate passage detector 111 detects this and a passage detection signal is transmitted to the main circuit 120.

The main circuit 120 detects the passage of the ball of the passage gate 11 by the passage detection signal from the gate passage detector 111. When the passage of the ball through the passage gate 11 is detected, A value is extracted from (not shown), and the lottery result of the usual drawing is stored in the usual drawing storage area (not shown) on the RAM 123 and held. Next, the main circuit 120 determines whether or not there is a lottery result hold in the common map in the RAM 123 storage area, and if there is a lottery result hold in the general map hold area. Then, it is determined whether or not the start winning device 13 that is an electric chew is open. If the start winning device 13 as an electric chew is not open, the main circuit 120 reads the oldest drawing drawing result held in the drawing holding storage area on the RAM 123. Subsequently, the main circuit 120 compares the read lottery result of the normal map with a predetermined standard map determination value, and determines a win / loss. The normal hit probability is 127/128, for example. If the determination result is successful, the main circuit 120 opens the start winning device 13 that is an electric chew by exciting the electric chew solenoid 115. The opening time of the start winning device 13 at the time of normal winning is, for example, 0.5 seconds at normal times, and, for example, 1.8 seconds × 3 times at the time of probability change and short time. Next, the main circuit 120 determines whether or not the accuracy change or the time reduction is in progress. If the accuracy change or the time reduction is in progress, the main circuit 120 waits for, for example, 1.8 seconds, and then de-energizes the electric Chu solenoid 115. Thus, the start winning device 13 as an electric chew is closed, and this opening / closing operation is repeated twice more. On the other hand, if it is not during the probability change or the time reduction, the main circuit 120 waits for e.g. 0.5 seconds to elapse, and then closes the start winning device 13 as an electric chew.

Regardless of whether the electric chew (movable blade) is opened or closed, when a ball wins the start winning device 13, the start winning detector 113 detects this and transmits a win detection signal to the main circuit 120.

The main circuit 120 detects the passage of the ball in the start winning device 13 based on the winning detection signal from the start winning detector 113, and when the passage of the ball in the start winning device 13 is detected, the special circuit random number A value is extracted from a counter (not shown) and a special drawing internal lottery is performed. The special drawing lottery storage area (not shown) on the RAM 123 is stored and held. In addition, the hit probability of the special figure can be set to, for example, 1/400 at the normal time and 1/40, for example, during the probability change. Next, the main circuit 120 instructs the payout device 108 to pay out a predetermined number of prize balls via the payout control board 107. Subsequently, the main circuit 120 determines whether or not the special figure lottery storage area on the RAM 123 is on hold, and if there is a special figure lottery hold on the special figure reservation storage area. Then, it is determined whether or not the change display of the previous special figure is being performed in the drum type display device 10 for gaming machines. If it is not during the fluctuation display of the previous special figure, the main circuit 120 determines whether or not the jackpot is being hit based on whether or not the jackpot flag is ON. If it is not a big hit, the main circuit 120 reads the lottery result of the oldest special figure from the special figure reserved storage area on the RAM 123. Next, the main circuit 120 determines whether the lottery result of the read special figure is a normal normal determination value or a probable change determination depending on whether it is a normal time (including a short time state) or a probable change time. The winning / losing determination is performed by collating with the value, and the variation time of the special figure, the effect pattern, the stop symbol, etc. are determined based on the winning / losing determination result. As the variation time of the special figure, the shorter the number of special figures held, the shorter the time is selected, and the shorter time can be selected during normal change and shorter time. Next, the main circuit 120 transmits, via the sub control board 101, a symbol variation signal for starting counting of a special symbol variation in the drum-type display device 10 for gaming machines and a special symbol variation timer (not shown). Transmit to the drum control board 104.

In the drum rotation processing, the drum control board 104 determines whether or not there is a rotation start instruction from the main circuit 120 via the sub control board 101 (S101 in FIG. 7), and if there is no rotation start instruction (FIG. 7). S101: NO), the drum rotation process is terminated. If there is a rotation start instruction (S101 in FIG. 7: YES), the drum control board 104 drives each of the left, middle, and right drum motors 30L, 30C, and 30R, so that each of the left, middle, and right drums is driven. High-speed rotation of 40L, 40C, and 40R is started (S102 in FIG. 7). However, since the radius increases in the order of the left drum 40L, the middle drum 40C, and the right drum 40R, the middle drum motor is compared with the rotational speed of the left drum motor 30L so that the three rows of symbols appear to fluctuate at the same speed. Control is performed such that the rotation speed of 30C is decreased and the rotation speed of the right drum motor 30R is decreased as compared with the rotation speed of the middle drum motor 30C.

Next, the drum control board 104 determines whether there is an instruction to stop the left drum 40L (S103 in FIG. 7). If there is no stop instruction for the left drum 40L (S103: NO in FIG. 7), the drum control board 104 waits until there is a stop instruction for the left drum 40L. When there is an instruction to stop the left drum 40L (S103 in FIG. 7: YES), the drum control board 104 stops the left drum 40L by performing deceleration control of the left drum motor 30L (S104 in FIG. 7).

Subsequently, the drum control board 104 determines whether there is an instruction to stop the middle drum 40C (S105 in FIG. 7). If there is no stop instruction for the middle drum 40C (S105: NO in FIG. 7), the drum control board 104 stands by until there is a stop instruction for the middle drum 40C. When there is an instruction to stop the intermediate drum 40C (S105 of FIG. 7: YES), the drum control board 104 stops the intermediate drum 40C by controlling the deceleration of the intermediate drum motor 30C (S106 of FIG. 7).

Next, the drum control board 104 determines whether it is reach based on the stop symbol of the left drum 40L and the stop symbol of the middle drum 40C (S107 in FIG. 7). If the reach is reached (S107 in FIG. 7: YES), the drum control board 104 controls the right drum motor 30R to rotate the right drum 40R at a low speed (S108 in FIG. 7). S107: NO), step S108 is skipped.

Subsequently, the drum control board 104 determines whether or not there is an instruction to stop the right drum 40R (S109 in FIG. 7). If there is no stop instruction for the right drum 40R (S109 in FIG. 7: NO), the drum control board 104 waits until there is a stop instruction for the right drum 40R. When there is an instruction to stop the right drum 40R (S109 of FIG. 7: YES), the drum control board 104 stops the rotation of the right drum 40R by controlling the reduction of the right drum motor 30R (S110 of FIG. 7). End the drum rotation process.

When the drum rotation processing by the drum control board 104 is completed, the main circuit 120 determines whether or not it is a stop at the big hit symbol. If it is a stop at the big hit symbol, the main circuit 120 turns on the big hit flag and determines whether or not the stop is at the probability variation symbol. If the stop is in the probability variation design, the main circuit 120 turns on the probability variation flag.

Next, the main circuit 120 determines whether or not the jackpot flag is ON. If the jackpot flag is ON, the number of rounds is used to open the jackpot 14 to the maximum number of rounds 15 with one jackpot. Is not the maximum number of rounds 15. If the number of rounds is not the maximum number of rounds 15, the main circuit 120 adds 1 to the number of rounds and energizes the big winning solenoid 115 to instruct the opening of the big winning device 14. As a result, the large winning device 14 is opened and a ball can be won. In addition, the payout of prize balls per prize is fifteen. When either one of the 10 winning balls per round is won in the grand prize winning device 14 or the maximum opening time of 25 seconds per round has elapsed since the grand prize winning device 14 is opened, The circuit 120 instructs the large winning device 14 to be closed by de-energizing the large winning solenoid 115. As a result, the large winning device 14 is closed and the ball cannot be won. Thereafter, since the big hit flag is still ON, the main circuit 120 repeatedly opens and closes the big winning device 14. When the number of rounds reaches the maximum number of rounds 15, the main circuit 120 resets the number of rounds to the initial value 0 and turns off the jackpot flag.

After jackpot processing, if it is a jackpot with a probability variation symbol, the jackpot will be in the probability variation state (the state where the probability of winning the jackpot is higher than usual) after the jackpot processing, and this probability variation state will win the next jackpot Continue until. In addition, when the jackpot of the non-probable variation symbol, after the jackpot ends, it becomes a short time state (a state in which the fluctuation time of the usual figure is shortened and the opening time of the start winning device 13 which is an electric chew is lengthened), It continues until the symbol variation of the special figure ends 100 times. (If you win in the internal lottery within 100 times, it will end at that point.)

According to the first embodiment, the radius of each of the left, middle, and right drums 40L, 40C, and 40R is displayed in the drum-type display device 10 for gaming machines that executes the internal lottery with the establishment of the predetermined condition and displays the lottery result. The number of symbols arranged on the outer periphery of each of the drums 40L, 40C, 40R is made different, and the distance between the outer periphery of each of the drums 40L, 40C, 40R and the display window 10a is made equal. In the same way as the conventional drum-type display device for gaming machines, the player has a special symbol placed only on a certain drum or has a number of symbols that gives the player a greater privilege. It becomes possible to arrange many on the drum.

Further, even when the number of symbols of each of the drums 40L, 40C, and 40R is varied, the speed of the symbols passing through the display window 10a is controlled to be equal in each row, so at first glance, a conventional drum for a gaming machine While giving the player the same impression as the expression display device, it is possible to give the player an unprecedented feeling that the rotation period of the symbols displayed from the display window 10a in each column is different.

Furthermore, since the drums 40L, 40C, and 40R each having a frustoconical shape in which the outer peripheral portion is formed by rounding a virtual right cone at different height positions are arranged so that the rotation axes are concentric, It is possible to give the player the pleasure of estimating the hidden relationship between the drums 40L, 40C, and 40R based on the number.

By the way, in the first embodiment, each of the left, middle, and right drums 40L, 40C, and 40R, which has a truncated cone shape obtained by rounding a virtual right cone at different height positions, has a rotation axis on the center axis of the right cone. The drums 40L, 40C, and 40R are arranged so that the distances between the drums 40L, 40C, and 40R are equal to the display window 10a at the outer peripheral portion on the player side. A similar effect can be obtained by arranging the rotation axis positions in parallel in a horizontal plane perpendicular to the vertical plane including the display window so that the distance between the display window and the outer periphery of each drum is equal. A drum-type display device for gaming machines can be realized.

FIGS. 8 and 9 show the display window 210a showing the rotation axes (center axes 260L, 260C, and 260R are shown) of the left, middle, and right drums 240L, 240C, and 240R, which are formed of three short cylinders having different radii. According to the second embodiment of the present invention, the distance between the display window 210a and the outer periphery of each of the drums 240L, 240C, and 240R is made equal by being shifted in a horizontal plane perpendicular to the vertical plane. It is the front view and top view which show the drum type display apparatus 210 for game machines.

In the drum-type display device 210 for gaming machines, the radius of the left drum 240L is smaller than the radius of the middle drum 240C, and the radius of the right drum 240R is larger than the radius of the middle drum 240C, and each drum 240L, 240C, 240R is attached to the output shafts of drum stepping motors (hereinafter referred to as drum motors) 230L, 230C, and 230R fixed to the left, middle, and right stay plate portions 220L, 220C, and 220R of the drum stay 220. The drums 240L, 240C, and 240R can rotate independently of each other. The left, middle, and right drums 240L, 240C, and 240R are shifted in parallel in a horizontal plane that is perpendicular to the vertical plane that includes the display window 210a, with the positions of the respective rotation axes (center axes 260L, 260C, and 260R). It arrange | positions and it arrange | positions so that the distance of the display window 210a and the outer peripheral part of each drum 240L, 240C, 240R may become equal.

Display backlights 250L, 250C, and 250R are disposed inside the respective drums 240L, 240C, and 240R at positions corresponding to the display windows 210a. The display backlights 250L, 250C, and 250R are fixed to the left, middle, and right stay plate portions 220L, 220C, and 220R of the drum stay 220, respectively.

The other portions are configured in the same manner as the corresponding members of the drum-type display device 10 for the gaming machine according to the first embodiment shown in FIGS. 1 to 7 and operate in the same manner, so that detailed description thereof is omitted. To do.

Even in the drum type display device 210 for gaming machines according to the second embodiment configured as described above, the same operation as that of the drum type display device 10 for gaming machines according to the first embodiment is performed, and the same effect can be obtained. Needless to say. In other words, the radii of the respective drums 240L, 240C, and 240R are made different so that the numbers of symbols arranged on the outer peripheral portions of the respective drums 240L, 240C, and 240R are made different, and the outer peripheral portions of the respective drums 240L, 240C, and 240R and the display windows. By equalizing the distance to 210a, it is possible to arrange a special symbol only on a certain drum, or to arrange a large number of symbols giving a greater privilege to a player on a certain drum. In addition, at first glance, while giving the player the same impression as the conventional drum-type display device for gaming machines, the player has an unprecedented feeling that the rotation period of the symbols displayed from the display window 210a is different in each row. Can be given. Further, it is possible to give the player the pleasure of estimating the hidden relationship between the drums 240L, 240C, and 240R based on the number of different symbols in each row.

By the way, regarding the drum-type display devices 10 and 210 for gaming machines according to the first and second embodiments, the following modifications can be considered.

In the first and second embodiments, the radius of the left drum is smaller than the radius of the middle drum and the radius of the right drum is larger than the radius of the middle drum. It may be larger or smaller. Further, the ratio of the radii of the respective drums can be freely designed.

In the first and second embodiments, the present invention is applied to the drum-type display device for gaming machines in which three rows of drums are arranged, but the drum-type display device for gaming machines in which two rows of drums are arranged. The present invention can be similarly applied to a drum-type display device for gaming machines in which four or more rows of drums are arranged.

The embodiments of the present invention have been described above. However, these are merely examples, and the present invention is not limited to them, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.

For example, in Examples 1 and 2, the gaming machine 1 is a pachinko gaming machine, but the drum-type display device 10 for gaming machines of the present invention may be used as a drum of a slot machine. In a normal slot machine, all drums are configured with the same radius, and the time for each drum to make one revolution is set to be the same. Therefore, by adopting drums with different radii and making the speeds of the symbols passing through the display window the same, the time for each drum to make one revolution will be different, so-called “stopping” to stop aiming at a particular symbol. Since the timing is also different for each drum, it is possible to provide a slot machine with a very high level of difficulty in the pressing technique. In addition, when drums with different radii are used in the slot machine, the moving speed of the symbols passing through the display window of each drum is different by equalizing the angular velocity of rotation when each drum is rotating at high speed. Thus, it is possible to provide a slot machine having a difficulty level of pressing depending on the drum.
