  The random number lottery means 54 generates 360 random numbers from 0 to 359 when the probability that the second symbols 38a to 38c after the change are in a specific mode is 1/360, for example, depending on the probability. A random number of numbers is generated, and on the condition that the second symbol starting means 15 detects a game ball, any one of the random number values is selected.

  The game determination means 55 determines whether or not the changed second symbols 38a to 38c are in a specific mode, that is, whether or not to generate a special game state, based on the lottery random number value in the random number lottery means 54. It is determined whether the lottery random value lottery lottery means 54 is a specific mode determination value (game state determination value), and when the lottery random number value is a specific mode determination value, the specific mode (game state) Occurrence) judgment output.

  The special game state generating means 58 specifies that the second symbols 38a to 38c after the fluctuation of the second symbol display means 21 are “7, 7, 7” or the like when the determination result of the game determining means 55 is the specific mode determination. This is for generating a special gaming state that is advantageous to the player based on the mode.

  The special game state generating means 58 opens the opening / closing plate 25 of the variable winning means 16 after the second symbols 38a to 38c after the variation of the second symbol display means 21 are in a specific mode, and opens the opening / closing plate 25. When a predetermined number of game balls have been won or a predetermined number of game balls have been won in the variable winning means 16 until the predetermined time has passed, the opening / closing plate 25 is closed, and the passage detection means 26b further detects the game balls passing through the specific area 26. The opening / closing operation (first game state) is continued up to a predetermined number of times (for example, 16 times) on the condition that it is detected.

  The stop symbol selection means 57 is for selecting the type of the second symbols 38a to 38c after the fluctuation of the second symbol display means 21 according to the determination result of the game determination means 55, and the determination result is a specific mode determination. Sometimes, one of a plurality of types of specific modes is selected by random number lottery, and the second symbols 38a to 38c after the change are set as the types of symbols, and the determination result is other than the specific mode determination. In this case, one of a plurality of types of non-specific modes is selected by random number lottery, and the types of symbols in which the second symbols 38a to 38c after the change become non-specific modes are set. In the non-specific mode, at least one of the three second symbols 38a to 38c is a different symbol.

  The variation pattern selection means 56 is for selecting one of many types (plural types) of variation patterns 39 by random lottery according to the determination result of the game determination means 55, and the determination result is At the time of specific mode determination, one of a variety of variation patterns 39 such as a normal reach variation pattern 39B, a first super reach variation pattern 39C, a second super reach variation pattern 39D, and a full rotation variation pattern 39E is selected. When the determination result is a non-specific mode determination, one of the no-reach variation pattern 39A and the reach variation patterns 39B to 39D is selected.

  In general, according to the reliability of each of the variation patterns 39B to 39E, the variation pattern 39 having a low reliability level in a specific mode is more likely to be selected by the variation pattern selection unit 56. The selectivity is high.

  The control command transmission means 59 is for transmitting a predetermined control command to the display control board 31 side by one-way communication to give a control command. When the second symbol starting means 15 detects a game ball, Based on the determination result of the game determination unit 55, the variation pattern 39 selected by the variation pattern selection unit 56, the stop symbol selected by the stop symbol selection unit 57, etc., the variation pattern commands and stop symbols of the second symbols 38a to 38c A command, a stop command, and the like are transmitted to instruct a change, stop, etc. of the second symbols 38a to 38c.

  In addition to the control function related to the variation control of the first symbol display means 20, the display control board 31 is related to the variation control of the second symbol display means 21, etc., the second symbol control means 60, the effect control means 61, Concealment control means 62 is provided. The second symbol control means 60 analyzes each command from the control command transmission means 59 on the condition that the second symbol start means 15 detects a game ball, and based on each command, the second symbol display means 21. The second symbols 38a-38c of 21 are fluctuated for a predetermined time with predetermined fluctuation patterns 39A-39E, etc., and the determination result of the game determination means 55 is a specific mode when the specific mode is determined, and a non-specific mode otherwise. Thus, the second symbols 38a to 38c are stopped.

  The effect control means 61 analyzes the change pattern command from the control command transmission means 59 and controls the effect display 40 appearing on the effect display means 22 based on the change pattern command. is there. The effect display 40 corresponds to, for example, the normal reach fluctuation pattern 39B, the first super reach fluctuation pattern 39C, the second super reach fluctuation pattern 39D, the total rotation fluctuation pattern 39E, etc. of the second symbols 38a to 38c. There are many types (plural types) such as 40B, first super reach variation effect display 40C, second super reach variation effect display 40D, and full rotation variation effect display 40E. And the production | control control means 61 has many kinds of production when there exists possibility that it will become a specific aspect including the case where the possibility (reliability) that the 2nd designs 38a-38c after a fluctuation | variation will become a specific aspect is high. One of the displays 40 is selected, and an effect command is issued at an appropriate time such as reaching reach during the fluctuation of the second symbols 38a to 38c, and the effect display 40 of the effect display means 22 is controlled. It has become.

  It should be noted that the effect display 40 is displayed until the determined time when the second symbols 38a to 38c after the change are in the non-specific mode, and until the end of the special game state when in the specific mode. In addition, a non-reach fluctuation effect display corresponding to the non-reach fluctuation pattern 39A of the second symbols 38a to 38c may be provided.

  The concealment control means 62 analyzes a variation pattern command from the control command transmission means 59 and controls the concealment means 23 to be changeable between a concealment state and a non-concealment state based on the variation pattern command and the like. In the normal state, the concealment member 41 is in the concealment state covering the effect display means 22 from the front side, and the second pattern 38a to 38c after the change is likely to be in the specific mode (reliability), including the specific mode and If there is such a possibility, it is configured to control to be in a non-hiding state in synchronization with the effect display 40 of the effect display means 22. Accordingly, the concealment control means 62 issues a concealment release command at an appropriate time such as reaching reach during the fluctuation of the second symbols 38a to 38c, and the concealment member 41 rises to the non-concealment state, and the second after the change. When the symbols 38a to 38c are in a non-specific mode, the solenoid 44 of the driving means 42 is controlled so that a concealment command is issued and the concealment member 41 is lowered into the concealment state after the end of the change when the symbols 38a to 38c are in the non-specific mode. It is possible.

  Next, the operation of the pachinko machine will be described. When a game ball is fired by the launching means 10 during a game, the game ball enters the game area 9 via the guide rail 12 and then wins the normal winning means 17-19 or the like while falling in the game area 9 Then, it falls downward while passing through the first symbol starting means 14. When the first symbol starting means 14 detects a game ball, the first symbol of the first symbol display means 20 fluctuates for a predetermined time and stops in a predetermined manner or a non-predetermined manner. When the first symbol is stopped in a predetermined manner, the opening / closing claw 24 of the second symbol starting means 15 is opened for a predetermined time, so that the game ball can easily win the second symbol starting means 15.

  When the opening / closing claw 24 of the second symbol starting means 15 is opened and a game ball is won, and when the second symbol starting means 15 detects a gaming ball, the random number lottery means 54 draws a generated random number value, and the game determining means 55 Is determined from the lottery random number value, the variation pattern selecting means 56 selects the variation pattern 39 according to the determination result, and the stop symbol selecting means 57 is changed after the second symbols 38a to 38c are changed. Select the stop symbol type. Then, the control command transmitting means 59 transmits the variation pattern command, stop symbol command, and stop command of the second symbols 38a to 38c to the display control board 31 side by one-way communication, and the variation and stop of the second symbols 38a to 38c. Etc.

  The second symbol control means 60 analyzes each command from the control command transmission means 59, and based on the command, the second symbols 38a to 38c of the second symbol display means 21 change with a predetermined fluctuation pattern 39 or the like for a predetermined time. The second symbols 38a to 38c are stopped in the specific mode when the determination result of the game determination means 55 is the specific mode determination, and in the non-specific mode otherwise.

  When the determination result of the game determination means 55 is the specific mode determination, the variation pattern selection means 56 selects one from the variation patterns 39, and the stop symbol selection means 57 selects from the number symbols 0 to 9, Any of the types of the second symbols 38a to 38c after the change is drawn by random lottery or the like. The control command transmission unit 59 transmits the variation pattern command of the variation pattern 39 selected by the variation pattern selection unit 56, the symbol command of the symbol selected by the stop symbol selection unit 57, and the like to the display control board 31 side. . As a result, the second symbols 38a to 38c change for a predetermined time with the predetermined fluctuation pattern 39 under the control of the second symbol control means 60, and then stop at the type of symbol designated by the stop symbol command to be in a specific mode. .

  For example, when the game determination means 55 determines that the specific mode is selected, the variation pattern selection means 56 selects the first super reach variation pattern 39C, and the stop symbol selection means 57 selects “7”, the second symbols 38a to 38c are After the reach of the first super reach fluctuation pattern 39C for a predetermined time by the control of the second symbol control means 60, the left and right are both "7", and finally specified in a special mode of "7,7,7" It becomes an aspect.

  When the changed second symbols 38a to 38c are in a specific mode, the special game state generating means 58 is then operated to generate a special game state, and the opening / closing plate 25 of the variable winning means 16 is opened forward. The variable winning means 16 closes the opening / closing plate 25 when a predetermined time elapses from the opening or when a predetermined number (for example, 10) of game balls wins within the predetermined time. When the winning game ball passes through the specific area 26, the opening / closing plate 25 is opened again, and the opening / closing operation is repeated up to a predetermined number of times (for example, 16 times).

  On the other hand, when the effect control means 61 and the concealment control means 62 analyze the change pattern command and reach the change in the first super reach change pattern 39C of the second symbols 38a to 38c, the effect control is performed as shown in FIG. Under the control of the means 61, a character corresponding to the first super reach fluctuation pattern 39C and other first super reach fluctuation effect display 40C appear on the effect display means 22, and the concealing member 41 of the concealing means 23 rises to a non-hiding state. Then, by the effect display 40 of the effect display means 22, a change in the first super reach change pattern 39C of the second symbols 38a to 38c is given to the player.

  As shown in FIG. 3, the concealment member 41 of the concealment unit 23 is normally in a concealment state in which the effect display unit 22 is concealed from the front side. However, when the second symbols 38a to 38c are reached, the movable iron core 45 of the solenoid 44 is retracted against the spring 52 by the concealment release command of the concealment control means 62, and the link 46 is moved around the pin 49 in the direction indicated by the arrow a. Therefore, the concealing member 41 rises and enters a non-concealing state as shown in FIG. Then, when the concealing means 23 is in the non-concealing state, the effect display means 22 displays the first super reach variation effect display 40C as a moving image at the same time or around that time.

  When the second symbols 38a to 38c after the change are in a non-specific manner, the concealing member 41 descends to conceal the effect display means 22 after the second symbols 38a to 38c are confirmed, and the first effect display means 22 The super reach fluctuation effect display 40C disappears. However, when the second symbols 38a to 38c after the change are in a specific mode, the concealing unit 23 continues the non-concealed state until the special gaming state by the special gaming state generating unit 58 is finally finished, during which the production is performed. A special game state is produced by the production display 40 displayed on the display means 22.

  Thus, the concealment means 23 for concealing the effect display 40 of the effect display means 22 is provided, and the concealment means 23 is changed between the concealment state and the non-concealment state, so that the effect only by the conventional effect display means 22 is achieved. In comparison, there is an advantage that it is possible to change the stage performance and arouse the interest of the player. In particular, when the concealing member 41 is moved up and down between the concealed state and the non-concealed state by the driving means 42 such as the solenoid 44, the structure can be simplified.

  8 and 9 illustrate a second embodiment of the present invention. In this embodiment, characters such as “reach!” Are used as the effect display 40, and the concealing means 23 is normally in a concealed state. When the second symbols 38a to 38c become reach, the concealing means 23 is brought into a non-hidden state, and the effect display means 22 causes the effect display 40 to appear.

During the variation of the second symbols 38a to 38c, as shown in FIG. 9A, the concealing member 41 of the concealing means 23 is lowered and is in the concealing state. As shown in FIGS. 8B to 8D, the second symbols 38a to 38c stop in the order of left, right, and center. In this case, stopping with symbols second symbol 38 a of the left, for example, with such as "7", the second FIG Pattern 3 8c of right therewith stops at symbol of the same type, shown in FIGS. 8 and 9 (D) Thus, the concealment member 41 rises to the non-concealment state, and the effect display 40 of “reach!” Of the effect display means 22 appears. In this way, the effect display 40 may be characters or other things.

FIG. 10 illustrates a third embodiment of the present invention. In this embodiment, the concealing means 23 is normally in a non-hidden state where the effect display 40 of the effect display means 22 can be recognized, and then the concealed state and non-concealed state. It changes to the concealment state. For example, as shown in FIG. 10A, the concealing member 41 is normally in the raised position in the non-concealing state. Then, during the fluctuation of the second symbol 38a-38c, as shown in FIG. 10 (A) (B), when the second symbol 38 a of the left is stopped at "7", etc., other appropriate point of "hits After the notice effect display 40 such as “!” Appears on the effect display means 22, if the left and right second symbols 38 a and 38 c become the same kind of reach, the concealing member 41 is once shown in FIG. As shown, the display is lowered to the concealed state, and the effect display 40 of the effect display means 22 is concealed. And if the 2nd symbols 38a-38c become a specific mode, as shown in Drawing 10 (D), concealment member 41 will rise to a non-hiding state, and effect display 40, such as "big hit" of effect display means 22, will be displayed. Appear.

  As described above, the concealing means 23 is normally in a non-concealed state, and the concealment member 41 during the variation of the second symbols 38a to 38c when the second symbols 38a to 38c after the variation are likely to be in a specific mode. May change from a non-hiding state to a hiding state. In addition, when the second symbols 38a to 38c after the change are likely to be in a specific mode, the concealed state and the non-hidden state may be repeated once or a plurality of times during the variation of the second symbols 38a to 38c. good.

  FIGS. 11 to 13 illustrate a fourth embodiment of the present invention. In this embodiment, the second symbol display means 21 and the effect display means 22 are configured separately, and the concealing member 41 of the concealing means 23 is provided.
