FIGS. 17A to 17H are state transition diagrams showing an example of symbol variation in the drum type display device 10.

Next, the operation of the drum-type display device 10 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 powering on the gaming machine 1, the balls prepared in the ball supply tray 5 are fired toward the game board 3 by the launching device 110 including the 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.

In the passage detection process, 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, and when it is detected that the ball has passed through the passage gate 11, A value is extracted from a figure random number counter (not shown), and it is determined whether or not the number of holds in the lottery result of the usual drawing is the maximum number of ordinary figure hold 4. If the holding number of the usual drawing lot result is the maximum holding number of normal drawing 4, the main circuit 120 ends the passage detection process. That is, the lottery result of the usual drawing exceeding the maximum number of ordinary drawing hold 4 is discarded without being held. If the number of hold of the usual drawing lot is not the maximum number of usual drawing hold 4, the main circuit 120 stores the lottery result of the usual drawing in the holding storage area for RAM (not shown) on the RAM 123 and holds it. Then, the normal map hold LEDs p1 and p2 of the normal map display unit 16 are turned on or blinked according to the number of the reserved lottery results of the normal map, and the passage detection process is terminated.

Next, in the general-purpose hold reading process, the main circuit 120 determines whether or not the general-purpose hold storage area (not shown) on the RAM 123 has a hold of the lottery result of the normal-use drawing. If there is no hold of the usual lottery result in the reserved storage area, the usual figure hold reading process is terminated. If there is a holding of the lottery result of the usual drawing in the holding storage area for the usual drawing on the RAM 123, the main circuit 120 determines whether or not the fluctuation display of the previous usual drawing is being displayed in the common drawing display unit 16. If the previous normal display is being displayed, the main circuit 120 ends the general-purpose hold reading process. If the fluctuation display of the previous usual figure is not being performed, the main circuit 120 determines whether or not the second start winning device 13 that is an electric Chu is being opened. If the second start winning device 13 that is the electric chew is open, the main circuit 120 ends the general-purpose hold reading process. If the second start winning device 13 that is the electric Chu is not open, the main circuit 120 reads out the oldest drawing drawing result held in the drawing storage area on the RAM 123 and displays the drawing. The ordinary map hold LEDs p1 and p2 of the unit 16 are turned on or blinked according to the number of retained lottery results of the ordinary drawing, and the ordinary map changing process is started.

In the normal map changing process, the main circuit 120 performs a win / loss determination by comparing the lottery result of the normal map read out in the general map hold reading process with a predetermined standard map determination value. The normal hit probability is 127/128, for example. Next, the main circuit 120 determines the normal fluctuation time depending on whether or not the probability is changing or the time is short. For example, if the probability is changing or the time is short, the variation time is determined to be 1 second, for example, and 30 seconds in normal time. Subsequently, the main circuit 120 starts to change the normal map by the normal map change LED 17 of the general map display unit 16. Next, if the determination result is lost, the main circuit 120 turns on the general map change LED 17 of the general map display unit 16 in orange, and ends the general map change processing. If the determination result is a win, the main circuit 120 lights the second figure variation LED 17 of the second figure display unit 16 in green and excites the electric chew solenoid 115 to thereby turn on the second start winning device 13 that is an electric chew. Open. The opening time of the second 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 is changing or the time is short. If the accuracy is changing or the time is short, for example, after waiting for 1.8 seconds, the main circuit solenoid 120 is turned off. By energizing, the second starting prize-winning device 13 that is an electric chew is closed, and this opening / closing operation is repeated twice more, and then the usual figure changing process is terminated. On the other hand, if it is not during the probability change or the time reduction, the main circuit 120, for example, waits for 0.5 seconds to elapse, and then closes the second start winning device 13 that is an electric chew, and performs the normal variation process. finish.

When a ball wins the first start prize device 12 or the second start prize device 13, the first start prize detector 112 or the second start prize detector 113 detects this, and a prize detection signal is sent to the main circuit 120. Send.

In the start winning detection process, the main circuit 120 passes the ball in the first start winning device 12 or the second start winning device 13 in accordance with a winning detection signal from the first start winning detector 112 or the second start winning detector 113. Is detected (S101 in FIG. 12), and if the passing of the ball is not detected (S101: NO in FIG. 12), the start winning detection process is terminated.

When the passage of the ball in the first start winning device 12 or the second starting winning device 13 is detected (S101: YES in FIG. 12), the main circuit 120 is held in the special-purpose holding storage area on the RAM 123. It is determined whether or not the number of holds in the lottery result of the special figure is the maximum special figure hold number 4 (S102 in FIG. 12). If the special figure lottery hold number is the maximum special figure hold number 4 (S102: YES in FIG. 12), the main circuit 120 pays out a predetermined number of prize balls to the payout device 108 via the payout control board 107. (S105 in FIG. 12) and the start winning detection process is terminated. That is, the lottery result of the special figure exceeding the maximum special figure holding number 4 is discarded without holding.

If the number of holds in the special drawing lottery result is not the maximum special figure hold number 4 (S102: NO in FIG. 12), the main circuit 120 extracts the value from the special figure random number counter (not shown) and displays the special figure. The internal lottery is conducted (S103 in FIG. 12), and the lottery result of the special figure is stored in the special figure holding storage area on the RAM 123 and held (S104 in FIG. 12). Note that the hit probability of a special figure can be 1/400 in normal times and 1/40 during probability change. The probability variation distribution rate can be 60%. At the same time, the main circuit 120 lights or blinks the special figure hold LEDs q1 and q2 of the special figure display unit 18 according to the number of the special figure lottery holds. 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 (S105 in FIG. 12), and ends the start winning detection process.

Next, in the special figure hold reading process, the main circuit 120 determines whether there is a special drawing lottery hold in the special figure hold storage area on the RAM 123 (S201 in FIG. 13). If there is no special drawing lottery hold in the figure hold storage area (S201: NO in FIG. 13), the special figure hold reading process is terminated.

If a special drawing lottery result is held in the special drawing storage area on the RAM 123 (S201 in FIG. 13: YES), the main circuit 120 uses the special drawing display unit 18 and the drum display device 10 to display the previous special drawing. It is determined whether or not the change display is being performed (S202 in FIG. 13). If the previous special figure is being displayed as a variable (S202: YES in FIG. 13), the main circuit 120 ends the special figure hold-read process.

If the previous special figure is not being displayed (S202: NO in FIG. 13), the main circuit 120 determines whether the jackpot is being hit based on whether the jackpot flag is ON (S203 in FIG. 13). ). If the jackpot is being hit (S203: YES in FIG. 13), the main circuit 120 ends the special figure hold reading process.

If the big hit flag is OFF (S203 of FIG. 13: NO), the main circuit 120 reads the lottery result of the oldest special figure from the special figure reserved storage area on the RAM 123 (S204 of FIG. 13). The variation process (see FIG. 14) is started (S205 in FIG. 13).

In the special figure changing process, the main circuit 120 determines whether the special figure lottery result read out in the special figure hold reading process is a normal normal judgment value or a probable change depending on whether it is normal or probable. The hit / miss determination is performed by collating with the hourly determination value, and the fluctuation time of the special figure, the stop symbol, etc. are determined based on the hit / miss determination result (S301 in FIG. 14). As for the fluctuation time of the special figure, a shorter time is selected as the number of holdings of the special figure is larger.

Next, the main circuit 120 changes the special figure of the special figure display unit 18, the rotation of the inner drums 53, 63, 73 in the drum type display device 10, the rotation of the outer drum 83, and the special figure fluctuation timer (not shown). Count) is started (S302 in FIG. 14).

Subsequently, the main circuit 120 determines whether or not the stop symbol has a V symbol (S303 in FIG. 14). If the stop symbol has a V symbol (S303 in FIG. 14: YES), the display control board 101 The slide movement of the outer drum 83 is controlled in accordance with the effect (S304 in FIG. 14). If there is no V symbol in the stop symbol (S303: NO in FIG. 14), the main circuit 120 skips step S304.

Next, the main circuit 120 determines whether or not the variation time has elapsed based on the variation timer of the special drawing (S305 in FIG. 14), and if the variation time has not elapsed (S305 in FIG. 14: NO), Wait until the fluctuation time has elapsed.

When the fluctuation time elapses (S305 in FIG. 14: YES), the main circuit 120 causes the fluctuation of the special figure in the special figure display unit 18, the rotation of the inner drums 53, 63, 73 in the drum type display device 10, and the outer drum 83. The rotation and the slide movement are stopped (S306 in FIG. 14). When winning, a winning symbol is displayed on the special figure display unit 18 and the drum type display device 10, and when lost, a lost symbol is displayed on the special figure display unit 18 and the drum type display device 10.

Next, the main circuit 120 determines whether or not it is a stop with a probability variation symbol or a non-probability variation symbol (S307 in FIG. 14).

If it is a stop with a probable variation or non-probability variation (S307 in FIG. 14: YES), the main circuit 120 turns on the jackpot flag (S308 in FIG. 14), and determines whether or not the stop is with a non-probability variation. (S309 in FIG. 14). If it is a stop with a non-probable variation symbol (S309 in FIG. 14: YES), the main circuit 120 ends the special figure variation process, and if it is not a stop with a non-probability variation symbol (S309: NO in FIG. 14), After turning on the flag (S312 in FIG. 14), the special figure variation process is terminated.

On the other hand, if it is not a stop with a probability variation symbol or a non-probability variation symbol (S307: NO in FIG. 14), the main circuit 120 determines whether it is a suspension with a random symbol (S310 in FIG. 14), and stops with a random symbol. If not (S310 of FIG. 14: NO), the special figure variation process is terminated. If it is a stop with a sudden symbol (S310 in FIG. 14: YES), the main circuit 120 turns on the small hit flag (S311 in FIG. 14), turns on the probability variation flag (S312 in FIG. 14), The variation process is terminated.

Subsequently, in the jackpot processing, the main circuit 120 determines whether or not the jackpot flag is ON (S401 in FIG. 15). If the jackpot flag is not ON (S401: NO in FIG. 15), the jackpot processing is terminated. To do.

If the jackpot flag is ON (S401 in FIG. 15: YES), the main circuit 120 determines whether the number of rounds is not the maximum number of rounds 15 in order to open the big winning device 14 up to the maximum number of rounds 15 with a single jackpot. It is determined whether or not (S402 in FIG. 15).

If the number of rounds is not the maximum number of rounds 15 (S402 in FIG. 15: YES), the main circuit 120 adds 1 to the number of rounds (S403 in FIG. 15) and excites the big prize solenoid 116 to excite the big prize device. 14 is instructed to open (S404 in FIG. 15). 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.

Whether 10 balls that can be won in one round win the grand prize winning device 14 (S405 in FIG. 15: YES), or whether the maximum open time of 25 seconds per round has elapsed since the grand prize winning device 14 opened ( When any one of S406 in FIG. 15 is satisfied, the main circuit 120 instructs the closing of the big winning device 14 by de-energizing the big winning solenoid 116 (S407 in FIG. 15), and the big hit processing Exit. 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 (S401: YES in FIG. 15), the main circuit 120 repeats opening / closing (S401 to S407) of the big winning device 14.

When the number of rounds reaches the maximum number of rounds 15 (S402: NO in FIG. 15), the main circuit 120 resets the number of rounds to the initial value 0 (S408 in FIG. 15), and turns off the jackpot flag (FIG. 15). S409), the jackpot processing is terminated.

After the jackpot process, if the jackpot is on a probability variation symbol or a random symbol symbol, the jackpot will be in a promising state (a state where the probability of winning the jackpot is higher than usual) after the jackpot processing, and this probability variation state is the next jackpot Continue until you win. In addition, when the jackpot of the non-probable variation symbol is reached, after the jackpot is over, the time is shortened (a state in which the fluctuation time of the usual figure is shortened and the opening time of the second start winning device 13 which is an electric chew is lengthened). Thus, the total symbol variation continues up to 100 times.

Subsequently, in the small hit process, the main circuit 120 determines whether or not the small hit flag is ON (S501 in FIG. 16). If the small hit flag is not ON (S501 in FIG. 16: NO), the main circuit 120 determines whether the small hit flag is ON. The hit process ends.

If the small hit flag is ON (S501 of FIG. 16: YES), the main circuit 120 opens the big winning device 14 to the maximum number of rounds 2 in one small hit, so that the number of rounds is the maximum number of rounds 2. Is determined (S502 in FIG. 16).

If the number of rounds is not the maximum number of rounds 2 (S502 of FIG. 16: YES), the main circuit 120 adds 1 to the number of rounds (S503 of FIG. 16) and excites the big prize solenoid 116 to excite the prize winning device. 14 is instructed to open (S504 in FIG. 16). 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.

Whether a single winning 10 balls per prize wins the grand prize winning device 14 (S505 in FIG. 16: YES), or the maximum opening time of 0.5 second elapses after the grand prize winning device 14 is opened. (S506 of FIG. 16: YES), the main circuit 120 instructs the closing of the big prize device 14 by de-energizing the big prize solenoid 116 (S507 of FIG. 16), The small hit processing is terminated. As a result, the large winning device 14 is closed and the ball cannot be won.

Thereafter, since the small hit flag is still ON (S501 of FIG. 16), the main circuit 120 repeats opening / closing (S501 to S507) of the big winning device 14.

When the number of rounds reaches the maximum number of rounds 2 (S502: NO in FIG. 16), the main circuit 120 resets the number of rounds to the initial value 0 (S508 in FIG. 16), and turns off the small hit flag (FIG. 16). 16 S509), the small hit processing is terminated.

17A to 17H show examples of symbol variation in the drum type display device 10. FIG. When the fluctuation starts from the stopped state shown in FIG. 17A as shown in FIG. 17B, the left symbol first stops as shown in FIG. 17C, and then as shown in FIG. 17D. The middle symbol stops and the player feels "lost". However, as shown in FIG. 17E, the rotation speed of the symbols in the right column becomes slow, and as shown in FIG. 17F, the outer drum 83 starts to slide and the V symbol appears from the inner drum 73. Will do. For this reason, as shown in FIG. 17 (g), the player suddenly changes whether it is a certainty change or is lost, and two V symbols are displayed as shown in FIG. 17 (h). Then it will be a decisive win and will be overjoyed. It is also possible to produce an effect such that the V drum of the inner drum 73 is shown for a moment during the symbol variation and then the outer drum 83 is returned.

As described above, in the drum-type display device 10 according to the first embodiment, the three inner drums 53, the inner drum 63, and the outer drum 83 on which the symbols 1 to 7 are usually drawn rotate, and the special drawing lottery result. Is displayed, but when there is a chance of winning or winning, the right outer drum 83 slides to the right by driving the outer drum moving motor 88 and moves to the right inner drum 73. The drawn V symbol appears (there is a pseudo effect in the case of a loss). The inner drum 73 in the right row and the outer drum 83 in the right row are always rotating in synchronism (when the inner drum 73 is not shown to the player, there is no problem even if the rotation of the inner drum 73 is stopped). ).

Note that various timings are possible for sliding the outer drum 83 in the right row. It may be immediately before the start of change or immediately before the stop of change. Immediately before the start of the change, the player sees the inner drum 73 in the right row to raise the expectation that “I may win in this lottery”, or the inner drum portion 53 in the left row and the inner drum 63 in the middle row The right side outer drum 83 is slid while moving the inner drum portion 73 in the right row slowly (so that the pattern can be recognized) or the outer drum 83 in the right row is also stopped from rotating. By sliding the outer drum 83 in the row, it is possible to provide a game unexpectedness to a player who thought that “this time is a loss”.

According to the first embodiment, in a gaming machine that performs an internal lottery in response to establishment of a predetermined condition and gives a player a privilege according to the symbol arrangement of the display unit displayed based on the lottery result, Adopt a drum as a part, make the drum a double structure, slide the outer drum in the direction of the rotation axis according to the production, make the inner drum appear, and change the pattern with a different pattern than before By doing so, it is possible to realize an unprecedented presentation and give the player unexpectedness and interest that are not conventional.

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

The intervals between the symbols in each row may be widened, and the drum portions 41, 42, 43 in all rows may have a double structure of an inner drum and an outer drum. By doing so, it becomes possible to change the symbols of all the rows and increase the width of the production.

If you don't want to increase the interval between symbols in each row, for the time being, only the drum portions 41 and 43 in both the left and right rows may have a double structure of an inner drum and an outer drum. Such a configuration is simpler than the three-row drum portions 41, 42, 43 having a double structure of an inner drum and an outer drum. As for production, for example, the design of the inner drums in both the left and right end rows is composed only of symbols that can be probable variation, and when one inner drum appears after the start of symbol variation, the expectation of probabilistic and big hit is high. Thus, when the inner drums in the left and right end rows appear, the probability of a probable big hit increases. Alternatively, a so-called “free symbol” may be prepared for the inner drums in the left and right end rows, and reach may be always achieved when the free symbol is displayed. In this case, when free symbols are displayed on the inner drums in the left and right end rows, the inner drum 63 in the middle row is a big hit regardless of which symbol is stopped.

Also, the number of symbol rows is not three, but may be any number such as two or four rows depending on the design. As the number of columns increases, the number of production patterns can be increased. However, if the number is too large, it becomes annoying and may reduce the player's willingness to play.

In addition, when the design of the outer drum is visible during normal times, there is no symbol that will be a big hit, and an inner drum with a symbol that will be a big winner will only appear when there is a chance (such as when a reach occurs). May be. By doing this, there is a sharpness between games that may win and games that do not.

Furthermore, during normal times, the design of the inner drum 73 is made visible, and the outer drum 83 appears only when a predetermined performance is performed or when a predetermined condition is satisfied, thereby concealing the design of the inner drum 73. The design of the drum 83 may be visible. Either the outer drum 83 or the inner drum 73 can be mainly used.

FIG. 18 is a cross-sectional view illustrating the drum-type display device 10 according to the second embodiment of the invention. The drum-type display device 10 according to the second embodiment includes a left row drum portion 141, a middle row drum portion 142, a right row drum portion 143, and an outer drum portion 144. The left drum unit 141 includes a fixed stay 151, an inner drum stepping motor (inner drum motor) 152 fixed to the fixed stay 151, and an inner drum 153 rotatably attached to the inner drum motor 152.

The middle drum section 142 includes a fixed stay 161, an inner drum stepping motor (inner drum motor) 162 fixed to the fixed stay 161, and an inner drum 163 rotatably attached to the inner drum motor 162. And a middle row of design sheets 164 attached to the outer periphery of the inner drum 163. The right-side drum section 143 includes a fixed stay 171, an inner drum stepping motor (inner drum motor) 172 fixed to the fixed stay 171, and an inner drum 173 rotatably attached to the inner drum motor 172. , And the right-side symbol sheet 174 affixed to the outer periphery of the inner drum 173.

As shown in FIGS. 19 and 20, the outer drum portion 144 is fixed to the output shaft on a slide stay 181 having a “U” -shaped side section and a rack 181 a protruding from the back surface of the slide stay 181. The output of the stepping motor for outer drum movement (outer drum movement motor) 182 meshed with the pinion 182a, the outer drum rotation motor 183 disposed at the lower right corner of the slide stay 181 and the outer drum rotation motor 183 An outer drum rotating gear 184 fixed to the shaft, a short cylindrical outer drum 185 meshed with outer gear 185 a carved on both outer peripheral edges of the outer drum rotating gear 184, and an outer periphery of the outer drum 185 A pair of symbol sheets 186 affixed to the upper left corner, lower left corner and upper right corner of the slide stay 181 are rotatably mounted one by one. 6 rotation auxiliary gears 187 meshed with the outer peripheral gear 185a of the outer drum 185, and eight moving auxiliary wheels 188 attached to the four corners of the upper end plate portion and the lower end plate portion of the slide stay 181. Has been.

Referring to FIG. 21, symbols composed of characters “12345678” from the top are sequentially described in the symbol sheet 154 in the left column. On the symbol sheet 164 in the middle row, symbols composed of characters “13571357” from the top are described in order. On the symbol sheet 174 in the right column, symbols composed of “24682468” characters from the top are described in order. In addition, on the symbol sheet 186 of the outer drum 185, symbols composed of characters “12345678” are described in order from the top.

FIGS. 22A and 22B are transition cross-sectional views illustrating the sliding movement of the outer drum 185 in the drum display device 10.

23A to 23C are transition front views for explaining the sliding movement of the outer drum 185 in the drum type display device 10.

FIG. 24A shows an example of an uncertain variable pattern in the drum display device 10 according to the second embodiment. In this example, a large hit of non-probable change is obtained by aligning the “444” doublets in the upper row. FIG. 24B illustrates an example of a probability variation pattern in the drum display device 10 according to the second embodiment. In this example, the large number of “777” in the upper line is a big hit of probability.

In addition, since other parts are configured in the same manner as the drum type display device 10 according to the first embodiment shown in FIGS. 1 to 17 and operate in the same manner, the corresponding parts are denoted by the same reference numerals, I will omit the detailed explanation of them.

In the drum type display device 10 according to the second embodiment configured as described above, when the inner drum motor 152, the inner drum motor 162, and the inner drum motor 172 are rotated or stopped, respectively, the inner drum 153, the inner drum 163, and the like. Each inner drum 173 rotates or stops.

When the outer drum rotating motor 183 is rotated or stopped, the outer drum 185 is rotated or stopped via the outer drum rotating gear 184. When the outer drum 185 rotates, the rotation assist gear 187 assists the rotation of the outer drum 185.

When the outer drum moving motor 182 rotates or stops, the slide stay 181 slides or stops via the pinion 182a and the rack 181a. As the slide stay 181 slides or stops, the outer drum 185 slides or stops. During the sliding movement of the slide stay 181, the auxiliary movement wheel 188 assists the sliding movement of the slide stay 181.

In the state where the inner drum 163 and the outer drum 185 in the middle row shown in FIG. 22 (a) are overlapped, as shown in FIG. 23 (a), the middle row is displayed from the display window (shown by a broken line) of the drum type display device 10. The design sheet 164 of the inner drum 163 is hidden and the design drawn on the design sheet 186 of the outer drum 185 is visible. When the outer drum moving motor 182 is rotated from this state, as shown in FIG. 22B, the slide stay 181 is slid to the right, which is the rotational axis direction, while being guided by the moving auxiliary wheel 188. Then, as shown in FIG. 23 (b), as shown in FIG. 23 (c), as shown in FIG. 23 (c), the outer drum 185 passes through the state where the outer drum 185 extends over the inner drum 163 in the middle row and the inner drum 173 in the right row. From the display window of the display device 10, the symbol sheet 174 of the inner drum 173 in the right row is hidden and the symbol drawn on the outer drum 185 can be seen.

As described above, the outer drum 185 that can be slidably moved is provided outside the inner drum 163 in the middle row and the inner drum 173 in the right row. Arranged at the column position. Simultaneously with the start of fluctuation of the special figure, the inner drums 153, 163, 173 and the outer drum 185 in the left middle right column simultaneously start to rotate. When the fluctuation of the special figure is stopped, the outer drum 185 stops at either the middle row or the right row. The lottery result of the special figure is displayed according to the symbols that can be seen when the operation stops.

Since the probability variation symbol is displayed on the inner drum 163 in the middle row and the non-probability variation symbol is displayed on the inner drum 173 in the right column, the outer drum 185 stops on the right column side when a big hit occurs in the probability variation symbol. The outer drum 185 stops on the middle row side when the big hit is caused by the non-probable variation pattern. The outer drum 185 can go back and forth between the middle row and the right row in accordance with the effect pattern from when the symbol variation is started until it completely stops. It is also possible to slide the outer drum 185 in accordance with the timing of all drums once again after stopping at any jackpot symbol. Depending on whether the outer drum 185 is in the middle row or the right row, the player's expectation with respect to the probability variation jackpot can be changed.

When the lottery result is a big hit, it is determined whether the outer drum 185 is in the middle row or the right row, whether it is a probable big hit or a non-probable big hit, so the player pays attention to the movement of the outer drum 185.

According to the second embodiment, depending on whether the outer drum 185 overlaps the inner drum 163 in the middle row or the inner drum 173 in the right row, the pattern that can be seen by the player is changed, and the state of the gaming machine 1 and the lottery result It is possible to provide unexpectedness to the player by suddenly appearing a different symbol sequence according to the situation, and change the degree of expectation to hit the jackpot depending on the degree of appearance. It will be possible to provide an unprecedented interest.

By the way, regarding the drum type display device 10 according to the second embodiment, the following modifications can be considered.

The arrangement of the symbols on each drum and the production pattern are not limited at all, and may be set as appropriate.

In normal times, the outer drum 185 may always be arranged at a specific place (for example, in the middle row), and the outer drum 185 may be slid only when a special effect or a specific lottery result is displayed. In this case, if a special symbol (such as a symbol dedicated to sudden winning) is prepared for the inner drum in the middle row, the display effect pattern can be increased as a symbol that is not displayed unless the outer drum 185 moves, You can also increase the types.

Further, the outer drum that is slidable is not limited to the middle row and the right row, and may be slid between the left row and the middle row. Alternatively, four drums for displaying the lottery result may be prepared, and an outer drum that can slide between the two left columns and an outer drum that can slide between the two right columns may be provided.

25A to 25C are cross-sectional views illustrating state transitions of the drum display device 10 according to the third embodiment of the invention. FIGS. 26A to 26C are front views illustrating state transitions of the drum display device 10 according to the third embodiment. The drum-type display device 10 according to the third embodiment includes a left row drum portion 241, a middle row drum portion 242, and a right row drum portion 243 arranged side by side.

The left row drum section 241 includes a fixed stay 251, an outer drum stepping motor (outer drum motor) 252 fixed to the fixed stay 251, and an outer drum 253 rotatably attached to the outer drum motor 252. The left-side symbol sheet 254 is attached to the outer periphery of the outer drum 253.

The middle row of drum portions 242 is rotatable to a slide stay 261, a pair of inner drum stepping motors (inner drum motors) 262a, 262b, and inner drum motors 262a, 262b fixed to the slide stay 261, respectively. The pair of inner drums 263a and 263b are attached, and the middle row of symbol sheets 264a and 264b are attached to the outer periphery of the inner drums 263a and 263b. The slide stay 261 is slidable in the rotational axis direction (left and right direction) of the inner drum motors 262a and 262b while being guided by the movement auxiliary wheel 265 by the rotation of the inner drum movement motor (not shown). .

The right drum unit 243 includes a fixed stay 271, an outer drum stepping motor (outer drum motor) 272 fixed to the fixed stay 271, and an outer drum 273 rotatably attached to the outer drum motor 272. The right-side symbol sheet 274 is attached to the outer periphery of the outer drum 273.

In the drum type display device 10 according to the third embodiment configured as described above, the inner drum 263b is exposed between the drum portion 241 in the left row and the drum portion 243 in the right row shown in FIG. In the state, the symbol drawn on the symbol sheet 264b of the inner drum 263b on the right side can be seen from the display window (shown by a broken line) of the drum type display device 10. When an inner drum moving motor (not shown) is rotated from this state, as shown in FIG. 25B, the slide stay 261 slides to the right, which is the rotational axis direction, while being guided by the moving auxiliary wheel 265. Moving. Then, as shown in FIG. 26B, the inner drum 263a and the inner drum 263b are exposed in half between the left row drum portion 241 and the right row drum portion 243, as shown in FIG. As shown in (c), the symbol drawn on the symbol sheet 264a of the left inner drum 242a can be seen from the display window of the drum-type display device 10.

Needless to say, the same effects as those of the first and second embodiments can be obtained in the third embodiment.

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 each embodiment, the gaming machine is a pachinko gaming machine, but the drum-type display device of the present invention may be used as a drum of a slot machine. If the outer drum is moved between the time when the start lever is operated and the time when the stop button is activated, the flow of the game need not be interrupted. In the slot machine, the player presses the stop button while watching the fluctuating symbols, but the inner drum appears when the outer drum slides, and the symbol arrangement changes, giving the player unexpected surprises. Giving and increasing interest in games.

In addition, the drum type display device of the present invention may be adopted in a slot machine so that a special symbol appears only in a special gaming state. For example, prepare a symbol arrangement that is aligned only during jackpots, and make the symbol invisible to the player (inside drum symbol) during normal times, and let the symbol appear only during jackpots (outer drum) , And the inner drum appears) so that it can be aligned only during the jackpot.

Furthermore, the drum type display device of the present invention may be used as a drum of a slot machine, and the player may be able to slide the outer drum by operating an operation button or the like. For example, if there is a design that can only be found on the outer drum, and whether or not the winning combination is determined depending on whether the design is in the middle row or the right row, the player relies on some effect or intuition. In addition, each time a game is played, the position of the outer drum is determined by operating a button or the like. Unprecedented game characteristics give a new interest to the player and increase the timing of participating in the game, so that the player's willingness to play can be enhanced. Further, by providing the operation means, the gameability of “moving the drum” which has not been conventionally added is added, and the interest of the player can be enhanced.

For example, if the winning combination a) “Bell-Bell-Star” plays 10 cards, and b) “Bell-Star-Bell” plays 15 cards, the star symbol is a symbol drawn only on the outer drum 185. When a) winning combination is won at the start, it is not established unless the outer drum is in the right row, and similarly, when b) winning combination is established, it is not established unless the outer drum is in the middle row. The display device provided in the slot machine displays when any of the above roles is established, and the player sees the display and presses the operation button as necessary to slide the position of the outer drum. Will be moved.

Further, in each embodiment, either one of the outer drum and the inner drum is configured to be movable, but these embodiments are combined, and both the outer drum and the inner drum are configured to be movable, and the gaming state The outer drum, the inner drum, or both drums may be moved according to the performance.
