Description

The present invention relates to a drum-type display device for gaming machines, and more particularly to a drum-type display device for gaming machines in which a plurality of drums are arranged so that their outer peripheral portions overlap.

In gaming machines, liquid crystal display devices and drum-type display devices are employed as means for displaying lottery results. Further, a drum type display device in which a plurality of drums are stacked in a row is also known.

When adopting a drum-type display device as a display means of a gaming machine, it is common that three drums are arranged side by side, and a privilege is given to the player by a combination of symbols displayed on a display window provided on the player side However, unlike a liquid crystal display device, a drum-type display device needs to be deep enough to accommodate the drum.

In Patent Document 1, a transparent symbol is arranged in a symbol row of the outer drum, and when the transparent symbol stops on the display window, the inner drum is rotated and the symbol of the inner drum is variably displayed through the display window. Although the technology is described, the symbol variation is in two stages, and the number of symbols for one round is not always increased as in the present invention.

Patent Document 2 describes a technique in which the outer peripheral portion of the outer drum is made of a transparent material, the symbols are arranged, and the winning drum is displayed on the inner drum by overlapping the symbols of the outer drum and the inner drum. In Patent Document 3, a pattern is arranged with the outer peripheral portion of the outer drum made of a transparent material, a background image and a background color are arranged on the inner drum, and the outer drum pattern and the inner drum background are arranged. However, none of the patent documents describes a method for increasing the number of symbols that can be variably displayed on the drum.

However, in the prior art, on the island where the gaming machine is installed, since it is necessary to provide various wirings and bill transport paths on the back of the gaming machine, the depth of the gaming machine cannot be increased without limit, and to some extent Must fit within the size of Therefore, each gaming machine has a problem that it is necessary to design the size of the drum and symbols and the number of symbols to be arranged while paying attention to the depth.

In view of such circumstances, the object of the present invention is to stack a plurality of drums in one row, arrange a plurality of symbols on each drum, and provide a transparent portion wider than the display window on the outer drum. An object of the present invention is to provide a drum-type display device for a gaming machine that can display more symbols than the number of symbols that can be arranged on a drum determined from the size of the drum, symbols, and symbol intervals.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-described problems, a drum-type display device for gaming machines according to the present invention includes a first drum including a symbol portion where a plurality of symbols are arranged, a transparent portion where no symbols are arranged, and a plurality of symbols. There and arranged pattern portion, and a transparent part which is not disposed of symbols, and a second drum which is disposed so as to overlap the inside of the first drum, the first drum pattern and said first drum A display window that allows a player to visually recognize a symbol within a certain range of symbols of the second drum that can be seen through the transparent portion, and a rotation control means that controls the rotation of the first drum and the second drum. The transparent portion of the first drum is formed over a wider range than can be seen from the display window, and the pattern portion of the second drum is in a wider range than the transparent portion of the first drum. Span It is formed Te, the rotation control means, when the symbol of the first drum is in a position not visible from the display window, and the rotational speed of the first drum slower than the rotational speed of the second drum, thereafter When the symbol of the second drum is in a position where it cannot be seen from the display window, the rotational speed of the second drum is made slower than the rotational speed of the first drum, and then the rotational direction of the symbol part of the first drum When the terminal portion exits from the display window rather than entering the display window, the first drum and the second drum are rotated at the same rotational speed, so that all of the first drums arranged on the first drum are rotated . A symbol row formed by combining symbols and all symbols arranged on the second drum is variably displayed on the display window.
According to the above-mentioned drum-type display device for gaming machines, a game in which a plurality of drums are stacked in one row and a symbol row is configured by combining symbols arranged on the outer peripheral portions of the outer drum and the inner drum. In the machine-type drum-type display device, when the symbols of both drums are combined, the number of symbols is equal to or more than one revolution of the drum, and the drum arranged at the outer periphery of the drum is rotated at a low speed or is not visible to the player. By stopping, it is possible to display more symbols to the player than the number of symbols that can be originally arranged on the outer periphery during one round. For this reason, since more symbols can be arranged compared to a single drum, the space for arranging the drums can be reduced (the depth can be designed to be narrow), and more symbols can be arranged on the drum. It is possible to give the player an unexpected feeling, enabling an unprecedented presentation, and giving the player a new interest.

In addition , the rotational speed of the drum whose symbol is no longer visible from the display window is controlled to be decelerated, and when the rotation direction end portion of the symbol portion of the first drum exits from the display window than when it enters the display window, the first drum of as the rotational speed and the rotational speed of the second drum are equal, thereby accelerating controlling the rotational speed of the second drum symbols were not visible through the display window is arranged to, the symbol of the first drum first The two-drum symbols can appear to scroll continuously, and the sense of unity of the first drum symbol and the second drum symbol as a symbol row can be enhanced.

The purpose is to display more symbols than the number of symbols that can be arranged, which is determined from the size of the drums and symbols, and the interval between symbols. This is achieved by arranging a pattern of the above and providing a transparent portion wider than the display window on the outer drum.

Next, the operation of the drum-type display device 10 for gaming machine 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 based on the passage detection signal from the gate passage detector 111. When it is detected that the ball has passed through the passage gate 11, the main circuit random number A value is extracted from a counter (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 that is 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 is displayed. A value is extracted from a random number counter (not shown) and a special drawing is internally drawn, and a 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.

When the drum control board 104 receives the symbol variation signal from the main circuit 120 via the sub-control board 101, the drum control board 104 starts drum rotation processing.

In the drum rotation process, the drum control board 104 determines whether or not the rotation flag is ON (S101 in FIG. 8). If the rotation flag is not ON (S101: NO in FIG. 8), the outer drum 40 Then, the rotation of the inner drum 50 is stopped (S107 in FIG. 8), and the drum rotation process is terminated. In a state where the outer drum 40 and the inner drum 50 are stopped, for example, as shown in FIG. 9, the player gives the symbols “1, 2” (in the drum unit 20R) of the outer symbol sheet 44 of the outer drum 40 through the display window 10a. "6, 5") is visible.

If the rotation flag is ON (S101 of FIG. 8: YES), the drum control board 104 is based on the position detection signals from the reference position detection sensors 34 and 35 and the symbols (in the lower part of the display window 10a) ( It is determined whether the lower symbol is “2-5” (S102 in FIG. 8).

If the lower symbol is “2-5” (S102: YES in FIG. 8), the drum control board 104 starts to rotate the outer drum 40 by rotating the drum motor 31, while the inner drum 50 is rotated. Is stopped (S103 in FIG. 8), and the drum rotation process is terminated.

When the outer drum 40 starts rotating in response to the rotation instruction and the outer drum 40 further rotates 180 degrees from the position shown in FIG. 9, for example, as shown in FIG. The symbol “5, 6” of the outer symbol sheet 44 (“2, 1” in the drum unit 20R) can be seen. For this reason, since the lower symbol is no longer “2-5” (S102: NO in FIG. 8), the drum control board 104 determines the lower symbol of the display window 10a based on the position detection signals from the reference position detection sensors 34 and 35. It is determined whether or not the symbol displayed on the screen is “8 to 11” (S104 in FIG. 8).

Now, since the lower symbol is “6” (“1” in the drum unit 20R) and not “8 to 11” (S104: NO in FIG. 8), the drum control board 104 rotationally drives the drum motors 31 and 32. As a result, the outer drum 40 is rotated and the inner drum 50 is rotated (S106 in FIG. 8), and the drum rotation processing is terminated. That is, the fact that the lower symbol is not “2-5” means that the outer symbol sheet 44 of the outer drum 40 does not correspond to the display window 10a, and the inner drum 50 becomes visible through the transparent portion 45. When the outer drum 40 further rotates from the position of FIG. 10, the inner drum 50 starts to rotate at the same speed as the outer drum 40 in conjunction with the outer drum 40.

FIG. 11 shows a state in which the outer drum 40 and the inner drum 50 are further rotated 45 degrees from the position of FIG. The outer symbol sheet 44 has “6” at the end (“1” in the drum unit 20R) visible on the upper stage of the display window 10a, and the inner symbol sheet 54 has the leading symbol “7” (“12” in the drum unit 20R) at the display window 10a. The boundary between the outer symbol sheet 44 and the inner symbol sheet 54 appears between them.

When the outer drum 40 and the inner drum 50 are further rotated 45 degrees from the position of FIG. 11, the drum control board 104 cannot see the outer design sheet 44 of the outer drum 40 from the display window 10 a, that is, the inner drum 50 passes through the transparent portion 45. The inner design sheet 54 becomes visible, and the outer drum 40 stops at that position (see the position of the outer drum 40 in FIG. 12).

Then, since the lower symbol becomes any one of “8 to 11” (S104 in FIG. 8: YES), the drum control board 104 stops the outer drum 40 by rotating the drum motor 32, while the inner drum 40 The drum 50 is rotated (S105 in FIG. 8), and the drum rotation process is terminated. For example, as shown in FIG. 12, the outer drum 40 is stopped and only the inner drum 50 is rotating.

The inner drum 50 continues to rotate, and the symbols “11, 12” (“8, 7” in the drum unit 20R) rotate to a position where it can be seen from the display window 10a. If the rotation continues further, the lower symbol is “8-11”. Since either one is eliminated (S104 in FIG. 8: NO), the drum control board 104 starts rotating the outer drum 40 in conjunction with the inner drum 50 (S105 in FIG. 8).

Thereafter, when the display window 10a moves to a position where the symbols “1, 2” (“6, 5” in the drum unit 20R) of the outer symbol sheet 44 of the outer drum 40 can be seen, the first position shown in FIG. 9 is restored. Since the lower symbol becomes “2 to 5” again (S102 of FIG. 8: YES), the drum control board 104 repeatedly controls the outer drum 40 and the inner drum 50 so that they take the positions of FIGS. . This operation is repeated while the drum unit 20 is rotating.

As described above, in the drum-type display device 10 for gaming machines in which only eight symbols can be arranged in one lap, the twelve symbols “1,” are displayed during the outer drum 40 making one lap (including a stopped state on the way). 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 "can be displayed (see FIG. 13). The rotation speed of the outer drum 40 and the inner drum 50 is well controlled to make a transition from a stopped state to a high speed rotation, a high speed rotation state, a transition from a high speed rotation to a low speed rotation, a transition from a low speed rotation to a stop state, etc. As with the conventional drum-type display device for gaming machines, it is possible to display the change smoothly and stop so that the player can realize that it is a double drum without being noticed by the player.

The drum control board 104 rotates the drum units 20L, 20C, and 20R in each row based on the lottery result of the internal lottery performed in response to the winning of the ball to the start winning device 13, and the drum units 20L, 20C, and 20R are rotated. The drum units 20L, 20C, and 20R in each row are stopped in the order of left, right, and center based on the stop instruction. Specifically, in the drum units 20L, 20C, and 20R, there is one symbol for the outer drums 40L, 40C, and 40R and the symbol for the inner drums 50L, 50C, and 50R that can be seen through the transparent portion 45 of the outer drums 40L, 40C, and 40R. A symbol row is formed, and a special drawing lottery result is displayed by a combination of symbols when the symbol is stopped. If the same number is three in a row at the time of a stop, it will be a big hit. At this time, the outer symbol sheet 44 is attached to the inner peripheral surface of the rim 43 of the outer drum 40 and the inner symbol sheet 54 is attached to the outer peripheral surface of the rim 53 of the inner drum 50. The level difference at the joint between the symbol and the symbol of the inner symbol sheet 54 is reduced, making it easier to see as one symbol row. Further, since the number of transparent members (front door 2 and rim 43) that block between the player and the outer symbol sheet 44 and the inner symbol sheet 54 is equal, it is easy to see as one symbol row.

When the drum units 20L, 20C, and 20R in each row are stopped in the order of left, right, and center by the drum rotation processing by the drum control board 104, the main circuit 120 determines whether or not the stop is a 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.)

In the first embodiment, the drum in which the symbol is not visible from the display window 10a stops rotating. However, if the transparent portion where the symbol is not arranged is made longer and the symbol becomes invisible from the display window 10a. You may make it rotate slowly, reducing a rotational speed, and accelerating gradually so that it can rotate at an original speed when it comes to the position where a design can be seen again. Since it is difficult to rotate at high speed suddenly from the stopped state as in the first embodiment (a motor with a large torque is required), it is better to do so (can be realized with an inexpensive motor).

According to the first embodiment, in the drum-type display device 10 for gaming machines that forms one symbol row by combining symbols arranged on the outer peripheral portions of the outer drum 40 and the inner drum 50, By combining the symbol with the drum 50, the number of symbols is equal to or more than one drum, and the drum placed at the outer periphery of the drum is rotated or stopped at a low speed by rotating or stopping the drum. In the meantime, more symbols can be displayed to the player than the number of symbols that can be placed on the outer periphery. That is, when the drum start condition is satisfied, the drum units 20 in each row start to rotate, and the boundary between the symbol sheet 44 and the transparent portion 45 of the outer drum 40 enters the display window 10a and exits from the display window 10a. When this is done, the rotation speed of the outer drum 40 and the rotation speed of the inner drum 50 are matched well, so that the player can make it appear that the single drum is normally rotating. For this reason, since more symbols can be arranged compared to a single drum, the space for arranging the drums can be reduced (the depth can be designed to be narrow), and more symbols can be arranged on the drum. It is possible to give the player an unexpected feeling, enabling an unprecedented presentation, and giving the player a new interest.

By the way, regarding the drum-type display device 10 for gaming machines according to the first embodiment, the following modifications can be considered.

In the first embodiment, the number of the symbols of the outer symbol sheet 44 of the outer drum 40 and the number of the symbols of the inner symbol sheet 54 of the inner drum 50 are six. However, the number is not limited to this number. The number of symbols arranged for each drum may be changed by changing the length of the sheet 44 and the inner symbol sheet 54 of the inner drum 50.

For example, if eight symbols are arranged on the outer peripheral portion of the inner drum 50 of the first embodiment, even 14 drums of the same size can be displayed with two more 14 symbols in one rotation. However, if the inner drum 50 is stopped while the symbol of the outer symbol sheet 44 of the outer drum 40 is visible from the display window 10a, the inner symbol sheet 54 of the inner drum 50 passes through the outer symbol sheet 44 of the outer drum 40. Since the design is blurred, it is possible to make the inner drum 50 look like a single drum if the transparent portion 55 larger than the display window 10a is provided.

14 to 19 are main part sectional views and display window display pattern diagrams showing transition of operation of the drum-type display device 10 for gaming machines according to the second embodiment of the present invention in which eight symbols are arranged on the inner drum 50. It is. In the drum type display device 10 for gaming machines according to the second embodiment, each drum unit 20 has a total of six symbols of “1”, “2”, “3”, “4”, “5”, “6”. The outer drum 40 formed of a transparent material including the rim 43 having the outer symbol sheet 44 disposed on the inner peripheral surface, and “7”, “8”, “9”, “10”, “11”, “ A state in which the outer peripheral portion is coaxially overlapped with the inner drum 50 including the rim 53 on which the inner symbol sheet 54 on which a total of eight symbols of “12”, “13”, and “14” are arranged is attached to the outer peripheral surface It is arranged and configured. Since the inner symbol sheet 54 on which eight symbols are arranged is attached to the entire outer peripheral surface of the rim 53, the inner drum 50 has (almost) no transparent portion.

FIG. 20 is a flowchart illustrating drum rotation processing by the drum control board 104 according to the second embodiment. This drum rotation process corresponds to the flowchart showing the drum rotation process by the drum control board 104 in the first embodiment shown in FIG. In the second embodiment, the rotation speed of the inner drum 50 includes a first rotation speed synchronized with the rotation speed of the outer drum 40 and a second rotation speed faster than the rotation speed of the outer drum 40. Is different.

Other parts not specifically mentioned are configured in the same manner as the drum-type display device 10 for the gaming machine according to the first embodiment shown in FIGS. 1 to 13, and therefore the corresponding parts are denoted by the same reference numerals. And I will omit those detailed explanations.

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

In the drum rotation process, it is determined whether or not the rotation flag is ON (S201 in FIG. 20). If the rotation flag is not ON (S201: NO in FIG. 20), the rotation of the outer drum 40 and the inner drum 50 is performed. Is stopped (S207 in FIG. 20), and the drum rotation process is terminated, but if the rotation flag is ON (S201: YES in FIG. 20), the symbol (lower symbol) displayed in the lower part of the display window 10a Is “2 to 5” (S202 in FIG. 20), “8 to 13” (S204 in FIG. 20), and others (ie, “1”, “6”, “7”, “ 14 "), the rotation and stop of the outer drum 40 and the inner drum 50 are controlled.

FIG. 14 shows the moment when the drum-type display device 10 for gaming machines is in a variable display (the rotation flag is ON) and the symbols “5, 6” of the outer drum 40 are visible through the display window 10a. When the symbol “6” of the outer drum 40 is displayed in the lower part of the display window 10a (S204: NO in FIG. 20), the transparent portion 45 appears continuously in the display window 10a, so the rotational speed of the outer drum 40 is adjusted. Then, the inner drum 50 also rotates at the first rotation speed synchronized with the rotation speed of the outer drum 40 (S206 in FIG. 20), and the symbol “7” of the inner drum 50 appears through the transparent portion 45 of the outer drum 40.

When both the outer drum 40 and the inner drum 50 are rotated 90 degrees from the state of FIG. 14, the design of the outer drum 40 is not visible from the display window 10a, and as shown in FIG. Since the symbol “7, 8” of the inner drum 50 becomes visible through the transparent portion 45 (S204 in FIG. 20: YES), the outer drum 40 stops rotating, while the inner drum 50 rotates at the first rotation speed. Continue (S205 in FIG. 20). The rotation of the outer drum 40 is stopped until the symbol “14” of the inner drum 50 is displayed in the lower part of the display window 10a.

As shown in FIG. 16, when the symbol “14” of the inner drum 50 is displayed in the lower part of the display window 10a (S204: NO in FIG. 20), the outer drum 40 rotates at a rotational speed synchronized with the inner drum 50. (S206 in FIG. 20), the symbol “1” of the outer drum 40 can be seen following the symbol “14” of the inner drum 50 in the lower stage of the display window 10a.

As shown in FIG. 17, when the symbols “1, 2” of the outer drum 40 are displayed on the upper and lower stages of the display window 10a and the symbol of the inner drum 50 becomes invisible (S202: YES in FIG. 20), from there The inner drum 50 is rotated at the second rotation speed by increasing the rotation speed (S203 in FIG. 20), and the inner drum 50 is rotated 270 degrees while the outer drum 40 is rotated 180 degrees.

When the outer drum 40 rotates 90 degrees from the state of FIG. 17 and the inner drum 50 rotates 135 degrees, as shown in FIG. 18, the symbols “3, 4” of the outer drum 40 are displayed on the upper and lower stages of the display window 10a. Is displayed.

When the outer drum 40 further rotates 90 degrees from the state of FIG. 18 and the inner drum 50 rotates 135 degrees, as shown in FIG. 19, the symbols “5, 6” of the outer drum 40 are displayed on the upper and lower stages of the display window 10a. ”Is displayed (S204 in FIG. 20: NO), and the design of the inner drum 50 becomes visible next, so that the inner drum 50 rotates from the first rotation that synchronizes with the rotation speed of the outer drum 40. The speed is reduced (S206 in FIG. 20), and the outer drum 40 and the inner drum 50 continue to rotate further from the state of FIG.

Thereafter, the symbol “7” of the inner drum 50 is displayed in the lower part of the display window 10a.

According to the second embodiment, the inner drum 50 is rotated twice while the outer drum 40 is rotated once (including the stopped state), whereby a total of 14 symbols are variably displayed on the display window 10a. Can do.

FIGS. 21 and 22 are cross-sectional views of relevant parts showing the transition of the operation of the drum-type display device 10 for gaming machines according to Embodiment 3 of the present invention. In the drum-type display device 10 for gaming machines according to the third embodiment, each drum unit 20 is configured in exactly the same manner as the drum-type display device 10 for gaming machines according to the second embodiment shown in FIGS. However, only the drum rotation processing of the outer drum 40 and the inner drum 50 is different. Accordingly, the parts that are not particularly mentioned are configured in the same manner as the drum-type display device 10 for gaming machines according to the second embodiment. Therefore, the corresponding parts are denoted by the same reference numerals, and detailed descriptions thereof are omitted. .

Next, the operation of the drum type display device 10 for gaming machines according to the third embodiment configured as described above will be briefly described with reference to FIGS. 21 and 22.

In the state shown in FIG. 17 in which the transparent portion 45 of the outer drum 40 is retracted from the display window 10a, the drum-type display device 10 for gaming machines according to the second embodiment increases the rotational speed of the inner drum 50. As shown in FIG. 21, the gaming machine drum-type display device 10 according to the third embodiment rotates the inner drum 50 in the opposite direction (counterclockwise as viewed in FIG. 21).

Then, as shown in FIG. 22, the transparent portion 45 of the outer drum 40 enters the display window 10a from the state shown in FIG. 17 where the transparent portion 45 of the outer drum 40 has left the display window 10a. Until the state, the outer drum 40 is rotated 180 degrees, while the inner drum 50 is rotated 90 degrees in the reverse direction.

According to the third embodiment, while the outer drum 40 makes one rotation (including the stopped state), the inner drum 50 rotates by one rotation + 90 degrees and then returns by 90 degrees. Individual symbols can be displayed in a variable manner.

As in the first to third embodiments, when changing the symbol at a constant speed, the drum displaying the symbol on the display window 10a maintains the constant speed, and the outer drum 40 displays the symbol on the display window 10a. The internal drum 50 decelerates, pauses, and accelerates when the symbol is not displayed on the display window 10a according to the size of the symbol portion by delaying the rotation timing by, for example, pausing when not being performed. The number of symbols that can be placed on the outer periphery of the drum by operating the drum portion to be aligned with the transparent portion 45 of the outer drum 40 by various drum rotation processes such as rotating in the opposite direction. More symbols can be displayed variably.

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.

In each embodiment, two symbols can be seen from the display window 10a. However, since the number of symbols seen from the display window depends on the size of the drum and the symbols, it can be freely designed.

In each embodiment, the drum units 20L, 20C, and 20R in each of the left, middle, and right rows are double drums, but only a part of the drum units may be double drums. A lot of symbols are displayed only for a part of the drums, and by arranging special symbols displayed only for the columns, it is possible to enhance the player's interest.

Further, even if a part or all of the drum units have a triple drum structure, it is possible to produce a highly effective effect. The triple drum is composed of an outer drum, an inner drum, and an inner drum, and at least the outer drum and the inner drum are provided with a transparent portion larger than the display window. From the state where the symbols of the outer drum are variably displayed, the middle drum is also rotated from the timing when the transparent portion of the outer drum appears in the display window, and the symbols of the outer drum and the middle drum are variably displayed. After that, when the outer drum symbol disappears, the outer drum is stopped and the middle drum symbol is variably displayed on the display window, and the inner drum also appears from the timing when the transparent part of the middle drum appears in the display window. Rotates and the symbols of the middle drum and inner drum are displayed in a variable manner. After that, when the design of the middle drum disappears, the middle drum is stopped and the display of the inner drum is changed and displayed in the display window, and then the outer drum also rotates to change the design of the inner drum and the outer drum. After entering the displayed state, the display returns to the state in which only the symbols of the outer drum are variably displayed. As a result, more symbols than those in the embodiments can be displayed in a variable manner or stopped.

Furthermore, in each embodiment, 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.
