  Although the schematic configuration of the pachinko gaming machine 1 has been described so far, the configuration of the pachinko gaming machine 1 described above is merely an example, and the board configuration of the gaming board 2 (arrangement of prizes related to winnings and lotteries) and the like are changed as appropriate. May be. For example, when the gaming machine according to the present invention is applied to a pachinko gaming machine that needs to be right-handed, a change is made such that the big prize opening 23, the gate 25, and the like are arranged in the gaming area 20 on the right side of the liquid crystal display 5. Is done.

  By the way, since the liquid crystal display 5 is fixed at a position that is easy for the player to visually recognize, the player's viewpoint is easily fixed when the period not winning the special symbol lottery lasts for a long time, and the game becomes monotonous. There is a fear. Therefore, the pachinko gaming machine 1 according to the present embodiment moves the EL display 6 automatically or based on the operation of the effect key 38 by the player, and displays the liquid crystal screen 50 (see FIG. 1) of the liquid crystal display 5. When the displayed display object (for example, a character) is moved to a position where it can be viewed through the EL screen 60 of the EL display 6, an image showing the display contents related to the display object is displayed on the EL screen 60. By doing so, it is configured such that an effective performance in which the player's viewpoint is hard to be fixed is performed.

  For example, as illustrated in FIG. 4A, when the EL display 6 moves to a position where the character displayed on the liquid crystal screen 50 can be seen through the EL screen 60, a decorative image that enhances the effect of the character. Is displayed on the EL screen 60. As a result, the character is displayed in a special manner that cannot be expressed by the liquid crystal screen 50 alone.

  For example, as illustrated in FIGS. 4B and 4C, when the EL display 6 moves to a position where the character displayed on the liquid crystal screen 50 is visible through the EL screen 60, the liquid crystal is displayed. A notice image of display contents for giving a notice of the state of the character as a result of the progress of the display effect performed on the screen 50 is displayed on the EL screen 60. In the example shown in FIG. 4B, a battle effect that is a big hit if a character wins against an enemy character as a display effect performed on the liquid crystal screen 50 during a special symbol variation display (during a reach effect). As a result, the image of the sword is used as a preview image so that the player can visually recognize the image of the character on the LCD screen 50 holding the sword, together with the character information “Chance !?” that predicts that the character will win. It is displayed on the EL screen 60. On the other hand, in the example shown in FIG. 4C, the character on the liquid crystal screen 50 is defeated in the battle together with the character information “Pinch !?” that warns that the character is defeated as a result of the battle effect. An image of the character indicating the state of being kneeled is displayed on the EL screen 60 as a preview image. Hereinafter, the configuration and operation of the pachinko gaming machine 1 for realizing such an effective display effect will be described.

[Configuration of Liquid Crystal Display 5]
The liquid crystal display 5 (an example of the first image display according to the present invention) is fixed to the housing of the pachinko gaming machine 1 that supports the game board 2. For this reason, the liquid crystal display 5 is fixed to the game board 2.

A liquid crystal display having an example of a first display screen is used. The liquid crystal display 5 displays an image output from an image sound control unit 140 (see FIG. 11) described later on the liquid crystal screen 50. On the liquid crystal screen 50, for example, display objects such as decorative symbols for informing the result of the special symbol lottery, characters and items for performing a notice effect, a hold display image indicating that the special symbol lottery is put on hold are displayed. The

  FIG. 5 is a diagram showing a schematic configuration of the liquid crystal screen 50. As shown in FIG. 5, the liquid crystal screen 50 has a large number of pixel units 51. Although 600 pixel units 51 are arranged in the vertical direction 11 and 800 pixel units are arranged in the horizontal direction 12, for convenience of explanation, in FIG. 5A, fewer pixel units 51 are shown than in actuality.

  The pixel unit 51 includes a color liquid crystal element 52 and an optical sensor 56. The color liquid crystal element 52 includes an R (Red) color liquid crystal element 53, a G (Green) color liquid crystal element 54, and a B (Blue) color liquid crystal element 55 that display the three primary colors. The optical sensor 56 is a light receiving element that detects light from the front of the liquid crystal screen 50, and is disposed adjacent to the R color liquid crystal element 53, the G color liquid crystal element 54, and the B color liquid crystal element 55 (see FIG. 5 (B)). Thus, the optical sensor 56 is disposed in proximity to each color liquid crystal element 52.

  When the optical sensor 56 receives light, an electrical signal corresponding to the brightness of the received light is generated. Each optical sensor 56 included in the liquid crystal screen 50 is connected to an effect control unit 130 (see FIG. 11) described later, and an electrical signal generated by each optical sensor 56 is output to the effect control unit 130. The effect control unit 130 detects the position of the EL screen 60 of the EL display 6 based on the electrical signal output from each optical sensor 56. Specifically, a frame 61 (see FIG. 7) of the EL display 6 to be described later has a surface facing the liquid crystal screen 50 of the liquid crystal display 5 formed in black, and is covered with the frame 61 on the liquid crystal screen 50. From the optical sensor 56 provided in the region, an electrical signal of a level different from the electrical signal output from the optical sensor 56 provided in the region not covered by the frame 61 is output.

The outer diameter dimension of the guide member 202 is set slightly smaller than the inner diameter dimension of the insertion hole 195, and the connecting member 194 is movable in the vertical direction 11 when the guide member 202 is inserted into the insertion hole 195. Supported by the guide member 202.

  The connecting member 197 is a member having the same shape as that of the connecting member 194, and a holding piece 199 that holds the insertion hole 198 through which the guide member 203 (see FIG. 9) is inserted and the second drive belt 207 (see FIG. 9). And have. The guide member 203 is a member having the same shape as the guide member 202 and is fixed to the housing of the pachinko gaming machine 1 so as to face the guide member 202 with a predetermined interval. The connecting member 197 is supported by the guide member 203 so as to be movable in the vertical direction 11 by inserting the guide member 203 through the insertion hole 198.

  Thus, since the connecting member 194 and the connecting member 197 are supported by the guide member 202 and the guide member 203, the first support member 201 can slide in the vertical direction 11.

  A first rotation shaft 204 is provided above the guide members 202 and 203, and a second rotation shaft 205 is provided below the guide members 202 and 203 (see FIGS. 7 and 8).

  The driving force of the first stepping motor 29 (see FIG. 11) is input to the gear 212 (see FIG. 7) of the first rotating shaft 204. Thereby, the 1st rotating shaft 204 to which the gear 212 was fixed rotates. Teeth that mesh with the teeth of the first drive belt 206 and the second drive belt 207 are formed on the outer circumferences of the pulleys 208 to 211, and the rotational force of the first rotating shaft 204 is first via the pulleys 208 and 209. It is transmitted to the drive belt 206 and the second drive belt 207. As a result, the first drive belt 206 and the second drive belt 207 move circumferentially, and the first rotation shaft 204 and the second rotation shaft 205 rotate synchronously. Since the connecting members 194 and 197 fixed to both ends of the first support member 201 are fixed to the first drive belt 206 and the second drive belt 207 by sandwiching pieces 196 and 199, the first stepping motor 29 The driving force is also transmitted to the first support member 201 and the EL display 6 supported by the first support member 201 moves in the vertical direction 11. Note that the direction of movement of the EL display 6 in the vertical direction 11 can be switched by switching the rotation direction of the first stepping motor 29 to forward rotation or reverse rotation.

  On the other hand, the slide drive mechanism 220 is roughly divided into a second support member 221, a guide member 222, a guide member 223, a first rotation shaft 224, a second rotation shaft 225, a first drive belt 226, and a second drive belt 227. I have.

  The second support member 221 is a thin plate member whose longitudinal direction is the vertical direction 11.

The outer diameter dimension of the guide member 222 is set slightly smaller than the inner diameter dimension of the insertion hole 215, and the connecting member 214 is movable in the horizontal direction 12 by inserting the guide member 222 into the insertion hole 215. Supported by the guide member 222.

  The connecting member 217 is a member having the same shape as the connecting member 214, and includes an insertion hole 218 through which the guide member 223 (see FIG. 9) is inserted, and a holding piece 219 that holds the first drive belt 226 (see FIG. 9). And have. The guide member 223 is a member having the same shape as the guide member 222, and is fixed to the housing of the pachinko gaming machine 1 so as to face the guide member 222 with a predetermined interval. The connecting member 217 is supported by the guide member 223 so as to be movable in the horizontal direction 12 by inserting the guide member 223 through the insertion hole 218.

  Thus, since the connecting member 214 and the connecting member 217 are supported by the guide member 222 and the guide member 223, the second support member 221 is slidable in the horizontal direction 12.

  A first rotating shaft 224 and a second rotating shaft 225 are provided outside the guide members 222 and 223 in the horizontal direction 12 (see FIGS. 7 and 8). The first rotating shaft 224 and the second rotating shaft 225 are rotatably supported by a bearing (not shown) such that the axial direction thereof coincides with the vertical direction 11. As shown in FIG. 9, the first rotating shaft 224 has a gear 232 and a pulley 228 fixed to one end thereof, and a pulley 229 fixed to the other end. The second rotating shaft 225 has a pulley 230 fixed to one end and a pulley 231 fixed to the other end.

  Between the pulley 228 and the pulley 230, an endless annular first drive belt 226 having teeth formed inside is stretched. A second drive belt 227 having the same configuration as the first drive belt 226 is stretched between the pulley 229 and the pulley 231.

  The driving force of the second stepping motor 30 (see FIG. 11) is input to the gear 232 (see FIG. 7) of the first rotating shaft 224. Thereby, the 1st rotating shaft 224 to which the gear 232 was fixed rotates. Teeth that mesh with the teeth of the first drive belt 226 and the second drive belt 227 are formed on the outer circumferences of the pulleys 228 to 231, and the rotational force of the first rotating shaft 224 is first via the pulleys 228 and 229. It is transmitted to the drive belt 226 and the second drive belt 227. As a result, the first drive belt 226 and the second drive belt 227 move circumferentially, and the first rotation shaft 224 and the second rotation shaft 225 rotate synchronously. Since the first driving belt 226 and the second driving belt 227 have connecting members 214 and 217 fixed to both ends of the second support member 221 fixed by sandwiching pieces 216 and 219, the second stepping motor 30 The driving force is also transmitted to the second support member 221 so that the EL display 6 supported by the second support member 221 moves in the horizontal direction 12. Note that the moving direction of the EL display 6 in the horizontal direction 12 can be switched by switching the rotation direction of the second stepping motor 30 to forward rotation or reverse rotation.

  Thus, the EL display 6 moves in the vertical direction 11 by the lifting drive mechanism 200 and moves in the horizontal direction 12 by the slide drive mechanism 220. In the present embodiment, since the EL display 6 moves in accordance with the operation information input from the effect key 38, the player can move the EL display 6 to a desired position.

[Configuration of Image Sound Control Unit 140]
FIG. 12 is a block diagram illustrating the configuration of the image sound control unit 140. As shown in FIG. 12, the image sound control unit 140 generates a control signal for instructing execution of various effects, and an image for expressing effects according to the control signal generated by the CPU 141. A VDP (Video Display Processor) 142 to be generated and an acoustic DSP (Digital Signal Processor) 143 to generate acoustic data for realizing an effect corresponding to the control signal generated by the CPU 141 are provided.

  A control ROM 144 and a RAM 145 are connected to the CPU 141. The control ROM 144 stores programs executed by the CPU 141, various data, and the like. The RAM 145 is used as a storage area for temporarily storing various data used when the CPU 141 executes the program, or a work area for data processing. Based on the command received from the effect control unit 130, the CPU 141 generates a control signal for controlling the operation of the VDP 142 and the acoustic DSP 143, and outputs the control signal to the VDP 142 and the acoustic DSP 143.

  An acoustic ROM 146 and an SDRAM 147 are connected to the acoustic DSP 143. The acoustic ROM 146 stores various acoustic data related to music, sound, sound effects, and the like output from the speaker 35. The SDRAM 147 is used as a work area for data processing by the acoustic DSP 143.

  The acoustic DSP 143 reads acoustic data corresponding to the control signal generated by the CPU 141 from the acoustic ROM 146 to the SDRAM 147, and performs necessary data processing on the acoustic data. Then, the acoustic data after the data processing is output to the speaker 35 via an amplifier (not shown) in synchronization with the image display on the liquid crystal screen 50 or the EL screen 60 or asynchronously with the image display.

  The VDP 142 functions as a display control unit that draws an image based on a control signal input from the CPU 141 and outputs the image to the liquid crystal display 5 and the EL display 6. The VDP 142 includes a CPU I / F 1421, a decoder 1422, a ROM I / F 1423, a drawing engine 1424, a VRAM_RS 1425, a VRAM_FB 1426, and an output circuit 1427. In this embodiment, the drawing engine 1424 functions as the drawing unit of the present invention, and the output circuit 1427 functions as the output unit of the present invention.

  The VDP 142 is provided with an internal bus 1428 and an internal bus 1429. The CPU I / F 1421, the decoder 1422, the ROM I / F 1423, the drawing engine 1424, and the VRAM_RS 1425 are connected to be communicable via an internal bus 1428. Further, the drawing engine 1424, the VRAM_FB 1426, and the output circuit 1427 are connected via an internal bus 1429 so as to communicate with each other.

  The CPU I / F 1421 is an interface that connects the VDP 142 and the CPU 141 in a communicable manner. A control signal generated by the CPU 141 is input to the VDP 142 via the CPU I / F 1421. The ROM I / F 1423 is an interface for reading image data from the image ROM 148.

  The image ROM 148 stores material data that is a material constituting an effect image displayed on the liquid crystal display 5 and the EL display 6. Specifically, image data related to characters, items, etc. for performing a decoration according to the size of a decorative pattern composed of three numbers and the degree of expectation, and image data related to a background image displayed as a background screen on the liquid crystal display 5 , Material data for realizing a so-called sprite function, such as image data relating to characters such as “reach” and “gekiatsu”, is stored.

  The VRAM_RS 1425 is a memory used as a storage area for temporarily storing material data read from the image ROM 148 or a work area for drawing processing executed by the drawing engine 1424. For example, when image data encoded by the Moving Picture Experts Group phase 2 (MPEG2) method is read from the image ROM 148, the image data decoded by the decoder 1422 is stored in the VRAM_RS 1425 as material data. The material data stored in the VRAM_RS 1425 is used for drawing processing performed by the drawing engine 1424. For this reason, by drawing material data frequently used in the drawing process in the VRAM_RS 1425, the drawing process by the drawing engine 1424 can be efficiently executed.

  The drawing engine 1424 draws an image to be displayed on the VRAM_FB 1426 on the liquid crystal screen 50 of the liquid crystal display 5 and the EL screen 60 of the EL display 6 based on a control signal from the CPU 141. Specifically, based on the control signal from the CPU 141 and the material data stored in the VRAM_RS 1425, the color of each pixel is calculated, and rendering processing for writing the calculated color value in the VRAM_FB 1426 is performed. An image drawn on the VRAM_FB 1426 is composed of a plurality of pixel data corresponding to an image for one frame, and each pixel data includes color information indicating R (Red), G (Green), and B (Blue). And an alpha value indicating the transparency of the pixel. The output circuit 1427 outputs the image drawn on the VRAM_FB 1426 to the liquid crystal display 5 and the EL display 6 at a predetermined display timing, and displays the image on the liquid crystal screen 50 and the EL screen 60. When only the liquid crystal display 5 is used, the drawing engine 1424 draws only an image to be displayed on the liquid crystal screen 50 on the VRAM_FB 1426 and the output circuit 1427 outputs the image to the liquid crystal display 5. .

  FIG. 13 is an explanatory diagram for describing a configuration of the VRAM_FB 1426. As illustrated in FIG. 13, the VRAM_FB 1426 is a double buffer type memory including a first frame buffer 1426 </ b> A and a second frame buffer 1426 </ b> B each storing an image for one frame drawn by the drawing engine 1424. The drawing engine 1424 draws an image of the next frame in the second frame buffer 1426B while outputting the image in the first frame buffer 1426A to the liquid crystal display 5 and the EL display 6. On the other hand, while the image in the second frame buffer 1426B is being output to the liquid crystal display 5 and the EL display 6, the image of the next frame is drawn in the first frame buffer 1426A. In this manner, the drawing engine 1424 can perform drawing processing at a high frame rate by performing drawing processing on the other frame buffer while outputting an image from one frame buffer.

  Incidentally, in the present embodiment, each of the first frame buffer 1426A and the second frame buffer 1426B has a memory area that can store pixel data of 720 dots in the vertical direction 11 and 960 dots in the horizontal direction 12. (See FIG. 16A). On the other hand, an image (hereinafter referred to as “main image”) displayed on the liquid crystal screen 50 of the liquid crystal display 5 is composed of pixel data of 600 dots in the vertical direction 11 and 800 dots in the horizontal direction 12. (See FIG. 16A). For this reason, when displaying an image only on the liquid crystal screen 50 of the liquid crystal display 5 without displaying an image on the EL screen 60 of the EL display 6, drawing processing can be performed without any problem. However, an image (hereinafter referred to as a “sub-image”) displayed on the EL screen 60 of the EL display 6 is composed of pixel data of 240 dots in the vertical direction 11 and 320 dots in the horizontal direction 12 (FIG. 16 ( C)), when the main image and the sub image are drawn side by side, the number of pixels in the vertical direction 11 or the horizontal direction 12 exceeds the number of pixel data that can be stored in the first frame buffer 1426A. It is impossible to draw the main image and the sub image together in the frame buffer 1426A. The same applies to the second frame buffer 1426B. Therefore, the VDP 142 according to the present embodiment draws the sub image divided into a plurality of areas in the empty area (see FIG. 16B) that is created after the main image is drawn in the first frame buffer 1426A. The main image and the sub image can be drawn together in the first frame buffer 1426A (or the second frame buffer 1426B). Hereinafter, the operation of the pachinko gaming machine 1 for realizing such drawing processing will be described in detail. In the following description, the case where the drawing process is performed using the first frame buffer 1426A will be described as an example, but the same process is performed when the drawing process is performed using the second frame buffer 1426B. Is called.

[Setting of divided image size and number of divisions]
In the first frame buffer 1426A and the second frame buffer 1426B, when the main image is drawn, an empty area that is not used for the drawing process is generated (see FIG. 15D). The sub image is drawn in this empty area, but if it cannot be drawn as it is in the empty area, it is drawn in the empty area as a divided image divided into a plurality of areas. The process of drawing the sub-image as a divided image is performed based on a preset divided image size SS and division number SN.

  Hereinafter, the process of setting the divided image size SS and the division number SN will be described with reference to FIGS. Here, FIG. 14 is a flowchart illustrating an example of setting processing executed by the CPU 141 of the image sound control unit 140. FIG. 15 is an explanatory diagram for explaining the main image size, the sub image size, the frame buffer size, and the size of the free area. FIG. 16 is an explanatory diagram for explaining a setting process executed by the CPU 141 of the image sound control unit 140. Note that the processing performed by the image sound control unit 140 described based on the flowcharts of FIG.

  For example, when the power of the pachinko gaming machine 1 is turned on, or when switching from a one-screen display using the liquid crystal display 5 to a two-screen display using the liquid crystal display 5 and the EL display 6, the divided image size A setting instruction command for instructing setting processing of the SS and the number of divisions SN is transmitted from the effect control unit 130 to the image sound control unit 140. On the other hand, the CPU 141 of the image sound control unit 140 determines whether a setting instruction command has been received (step S1). If the CPU 141 determines that the setting instruction command has not been received (step S1: NO), a standby state is entered.

  When it is determined that the setting instruction command has been received (step S1: YES), the CPU 141 acquires the main image size, the sub image size, and the frame buffer (FB) size (step S2). Specifically, the frame buffer sizes of the first frame buffer 1426A and the second frame buffer 1426B are acquired from the VDP 142 and stored in the RAM 145, and the screen resolution of the liquid crystal screen 50 and the screen resolution of the EL screen 60 are set to the main image size and The sub image size is acquired from the liquid crystal display 5 and the EL display 6 via the VDP 142 and stored in the RAM 145. Here, as shown in FIG. 15A, the frame buffer size includes the number of pixels L1 in the vertical direction 11 and the horizontal direction 12 of the pixel data that can be stored in the first frame buffer 1426A (or the second frame buffer 1426B). In this embodiment, the information is 720 × 960 (vertical pixel number L1 × horizontal pixel number C1) (see FIG. 16A). As shown in FIG. 15B, the main image size is information indicating the number of pixels L2 in the vertical direction 11 and the number of pixels C2 in the horizontal direction 12 of the pixel data constituting the main image. In this embodiment, the resolution is equal to 600 × 800 (vertical pixel number L2 × horizontal pixel number C2) (see FIG. 16A). As shown in FIG. 15C, the sub image size is information indicating the number of pixels L3 in the vertical direction 11 and the number of pixels C3 in the horizontal direction 12 of the pixel data constituting the sub image. The resolution is equal to 240 × 320 (vertical pixel number L3 × horizontal pixel number C3) in this embodiment (see FIG. 16C).

Next, the CPU 141 calculates the size of the empty area that occurs after the main image is drawn in the first frame buffer 1426A based on the acquired main image size and frame buffer size (step S3). Specifically, by using the following arithmetic expression, the minimum vertical pixel number L4 (see FIG. 15D) and the minimum horizontal pixel number C4 (see FIG. 15D) of the pixel data that can be drawn in the empty area. Is calculated.
Minimum vertical pixel number L4 = vertical pixel number L1-vertical pixel number L2
Minimum horizontal pixel number C4 = horizontal pixel number C1−horizontal pixel number C2
In the present embodiment, as shown in FIG. 16, since the vertical pixel number L1 is “720” and the vertical pixel number L2 is “600”, “120” is calculated as the minimum vertical pixel number L4, and the horizontal Since the pixel number C1 is “960” and the horizontal pixel number C2 is “800”, “160” is calculated as the minimum horizontal pixel number C4 (see FIG. 16B).

Subsequently, the CPU 141 calculates the total number ST of pixel data constituting the sub-image and the total number VT of pixel data that can be drawn in the empty area using the following arithmetic expression, and whether the total number ST is smaller than the total number VT. It is determined whether or not (step S4).
Total number ST = vertical pixel number L3 × horizontal pixel number C3
Total number VT = vertical pixel number L4 × horizontal pixel number C1 + horizontal pixel number C4 × (vertical pixel number L1−vertical pixel number L4)
Here, the vertical pixel number L3 is the number of pixels in the vertical direction 11 of the pixel data constituting the sub-image, and the horizontal pixel number C3 is the number of pixels in the horizontal direction 12 of the pixel data constituting the sub-image. After calculating the total number ST and the total number VT, the CPU 141 determines whether or not the total number ST is smaller than the total number VT. If the total number ST is smaller than the total number VT, it can be determined that the sub-image can be drawn in the first frame buffer 1426A as it is or divided. On the other hand, if the total number ST is larger than the total number VT, it can be determined that even if the sub-image is divided, it cannot be drawn in the first frame buffer 1426A as it is.

  When determining that the total number ST is smaller than the total number VT (step S4: YES), the CPU 141 functioning as the division determination unit determines whether the sub image needs to be divided in order to draw the sub image in the empty area. Determine (step S5). Specifically, the number of vertical pixels L3 (see FIG. 15C) of the pixel data constituting the sub image is smaller than the minimum number of vertical pixels L4 (see FIG. 15D) of the empty area, or the sub image. Whether or not the number of horizontal pixels C3 (see FIG. 15C) of the pixel data constituting the image data is smaller than the minimum number of horizontal pixels C4 in the empty area (see FIG. 15D). Determine. Here, if the number of vertical pixels L3 is smaller than the minimum number of vertical pixels L4 or the number of horizontal pixels C3 is smaller than the minimum number of horizontal pixels C4, it is possible to draw the sub-image in an empty area without dividing it. It can be determined that there is. On the other hand, when the vertical pixel number L3 is larger than the minimum vertical pixel number L4 and the horizontal pixel number C3 is larger than the minimum horizontal pixel number C4, the sub image cannot be drawn as it is in the empty area, so the sub image is divided and drawn. It can be determined that it is necessary. As described above, the CPU 141 determines the necessity of dividing the sub image based on the size of the empty area and the sub image size.

  When the CPU 141 determines that the division is unnecessary (step S5: NO), the CPU 141 sets the division number SN to “0” (step S6). Here, the division number SN is information indicating the number of divided images drawn in the empty area. In other words, the division number SN is information indicating the number of divided images constituting the sub image. The division number SN set in step S6 is stored in the RAM 145 as setting information. This setting information is included in the control signal output to the VDP 142 and sent to the VDP 142. As will be described in detail later, when the division number SN is set to “0”, the divided image is not drawn in the empty area, and the sub image is drawn as it is.

When the CPU 141 functioning as a calculation unit determines that the division is necessary (step S5: YES), the CPU 141 calculates the divided image size SS and the division number SN based on the free area size and the sub image size (step S7). . Here, the divided image size SS is information indicating the size (the number of vertical pixels and the number of horizontal pixels) of one divided image when the sub-image is divided into the number of divided images indicated by the division number SN. is there. In step S7, the divided image size SS (the vertical pixel number SSL of the divided image and the horizontal pixel number SSC of the divided image) and the divided number SN are calculated using the following arithmetic expressions.
The number of vertical pixels of the divided image SSL = the minimum number of vertical pixels L4
The number of horizontal pixels SSC of the divided image = the minimum number of horizontal pixels C4
Number of divisions SN = (vertical pixel number L3 / minimum vertical pixel number L4) × (horizontal pixel number C3 / minimum horizontal pixel number C4)
As shown in FIGS. 16B and 16C, in this embodiment, “120” is calculated as the minimum vertical pixel number L4, and “160” is calculated as the minimum horizontal pixel number C4. Therefore, the divided image size SS here is 120 × 160 (vertical pixel number SSL × horizontal pixel number SSC). The division number SN is calculated as “4” by (240/120) × (320/160).

  After calculating the divided image size SS and the number of divisions SN, the CPU 141 stores the calculated divided image size SS and the number of divisions SN as setting information in the RAM 145 (step S8). This setting information is included in the control signal output to the VDP 142 and sent to the VDP 142. When the setting process of step S6 is performed instead of the setting process of step S8, the divided image size SS is not calculated because there is no need to divide the sub-image, and the division number SN is set as “setting information”. Only information indicating “0” is sent to the VDP 142.

  Here, the relationship between the divided image size SS and the free area size when the divided image size SS and the number of divisions SN are changed will be described with reference to FIG. When the division number SN is set to “0” for the sub-image having the vertical pixel number L3 of “240” and the horizontal pixel number C3 of “320” (when the process of step S6 is performed). As apparent from FIGS. 16B and 16C, since the number of vertical pixels L3 exceeds the minimum number of vertical pixels L4 and the number of horizontal pixels C3 exceeds the minimum number of horizontal pixels C4, the first frame A sub-image cannot be drawn as it is in the empty area of the buffer 1426A.

  Further, if the division number SN is set to “2”, the first sub-image is drawn in the empty area as two divided images having a vertical pixel number of “240” and a horizontal pixel number of “160”. And a second method of drawing the sub-image in the empty area as two divided images having a vertical pixel count of “120” and a horizontal pixel count of “320” (middle of FIG. 16C). (Refer to the figure below.) However, when drawing a sub-image by the first method, it is possible to draw two divided images in a region (see FIG. 16B) extending in the vertical direction 11 in the empty region. However, a divided image cannot be drawn in an area extending in the horizontal direction 12 in the empty area. This is because the number of vertical pixels “240” of the divided image exceeds the minimum number of vertical pixels L4 (= 120) in the empty area. In addition, when considering sub-image drawing by the second method, it is possible to draw two divided images in a region (see FIG. 16B) extending in the horizontal direction in the empty region. Two divided images cannot be drawn in an area extending in the vertical direction 11 in the empty area. This is because the horizontal pixel number “320” of the divided image exceeds the minimum horizontal pixel number C4 (= 160) of the empty area. As described above, when the number of divisions SN is set to “2” when the sub image illustrated in this embodiment is drawn as a divided image in the empty area, the divided image is drawn in the empty area depending on the position where the divided image is drawn. Cases that cannot be done may occur.

  On the other hand, when the number of divisions SN is set to “4” as described above, the vertical pixel number SSL is an empty area, as is apparent from the diagrams on the right side of FIGS. 16B and 16C. Is set to “120” which is the same as the minimum vertical pixel number L4, and the horizontal pixel number SSC is set to “160” which is the same as the minimum horizontal pixel number C4 of the empty area. Then, four divided images of this divided image size SS are drawn in the empty area. In this case, each divided image can be drawn in either the area extending in the vertical direction 11 or the area extending in the horizontal direction 12 in the empty area. Therefore, unlike the case where the division number SN is set to “2”, there is no case where the divided image cannot be drawn in the empty area depending on the position where the divided image is drawn. As described above, the number of divisions SN and the divided image size SS are set to appropriate values so that the divided images can be surely fit in the empty area regardless of the arrangement of the divided images drawn in the empty area.

  On the other hand, if the CPU 141 determines that the total number ST is larger than the total number VT in step S4 (step S4: NO), even if the sub-image is divided, all the pixel data constituting the sub-image are set as free areas. It is impossible to draw. Therefore, when the CPU 141 determines that the total number ST is larger than the total number VT (step S4: NO), the CPU 141 calculates a reduction ratio (step S9), and stores the calculated reduction ratio in the RAM 145 as setting information (step S9). S10). Then, the process proceeds to steps S7 and S8, and the divided image size SS and the division number SN are set.

  Here, a method for setting the reduction ratio will be described. For example, when the reduction ratio is set to “0.5” in step S9, the sub-image (the figure on the left side of FIG. 16C) in which the vertical pixel number L3 is “240” and the horizontal pixel number C3 is “320”. As a sub-image having a vertical pixel number L3 of “120” (= 240 × 0.5) and a horizontal pixel number C3 of “160” (= 320 × 0.5), steps S7 and S8 are performed. Processing is performed. In this case, in the rendering process, a sub image in which the number of pixels in the vertical direction 11 and the horizontal direction 12 is halved is generated on the VRAM_RS 1425, and the sub image is a divided image based on the divided image size SS and the division number SN. Are drawn in the empty area of the first frame buffer 1426A. These divided images are output to the EL display 6 after scaling processing (enlargement processing) for doubling the number of pixels in the vertical direction 11 and the horizontal direction 12 is performed by the drawing engine 1424. This makes it possible to draw a sub-image that cannot be drawn in the empty area even if it is divided, in the empty area. Therefore, in a pachinko gaming machine having an image display device having a large screen resolution with respect to the free space size, the problem that the conventional drawing process cannot display an image on the image display device is that the divided image size SS and the number of divisions. This can be solved by setting a reduction ratio in addition to SN.

  Note that the reduction magnification is such that, for example, the total number of sub-images after reduction (= the number of vertical pixels × the number of horizontal pixels) is less than or equal to the total number VT of pixel data that can be drawn in a free area (preferably smaller than the total number VT by a predetermined number or more) Value). This makes it possible to draw the sub image as a divided image in the empty area. However, if the reduction ratio is too small, the image quality of the image displayed on the EL display 6 as a result of the scaling process may be deteriorated. Therefore, the reduction ratio is set so that the total number of pixels of the sub-image after reduction is the total number VT. It is preferable to set the value as large as possible within a range not exceeding.

  When the setting process based on the flowchart of FIG. 14 described above is performed, information indicating whether or not the sub image needs to be reduced when the main image and the sub image are drawn in the first frame buffer 1426A, and the case where the reduction is necessary Is set with a reduction ratio, information indicating whether or not sub-image division is necessary, and a division image size SS and a division number SN (when the division number SN = 0, only the division number SN) is set. Information is stored in the RAM 145 as information. Drawing processing for two-screen display by the drawing engine 1424 described later is executed based on this setting information.

  When executing a one-screen display using only the liquid crystal display 5, the CPU 141 outputs a control signal that does not include the setting information stored in the RAM 145 by the setting process to the VDP 142. As a result, only the main image is drawn on the VRAM_FB 1426, and a one-screen display using only the liquid crystal display 5 is performed. On the other hand, when executing two-screen display using the liquid crystal display 5 and the EL display 6, the CPU 141 outputs a control signal including setting information to the VDP 142. As a result, the main image and the sub image are drawn on the VRAM_FB 1426, and the two-screen display using the liquid crystal display 5 and the EL display 6 is performed. In this way, the CPU 141 can appropriately perform the drawing process by switching and outputting the control signal not including the setting information and the control signal including the setting information. Further, by performing the setting process, for example, even when the screen resolution of the EL screen 60, that is, the sub image size changes due to reuse of the EL display 6, the first frame buffer 1426A or the second frame buffer 1426B has a free space. It is possible to appropriately draw the sub-image.

[Main operations of game control unit 100]
Next, main operations performed in the game control unit 100 will be described. FIG. 17 is a flowchart illustrating an example of main operations performed by the game control unit 100. The game control unit 100 repeatedly executes a series of processes shown in FIG. 17 every predetermined time (for example, 4 milliseconds) in a normal operation except for a special case such as when the power is turned on or when the power is turned off. . Note that the processing of the game control unit 100 described based on the flowcharts from FIG.

  In the random number update process (step S11), the game control unit 100 updates various random numbers such as a jackpot random number, a symbol random number, a reach random number, a variation pattern random number, and a normal symbol random number. Here, the big hit random number is a random number for determining the winning (big hit or small hit) or the loss (losing) of the special symbol lottery. The symbol random number is a random number for determining a winning type (long hit, short hit, presence / absence of transition to a high probability state, presence / absence of transition to a short-time gaming state) when a special symbol lottery is won. The reach random number is a random number for determining whether to perform an effect with reach or an effect without reach when the special symbol lottery is lost. The variation pattern random number is a random number for determining a variation pattern when a special symbol is displayed in a variable manner. The normal symbol random number is a random number for determining whether the normal symbol lottery is won or lost. The jackpot random number, the design random number, the reach random number, the variation pattern random number, and the normal design random number are incremented by “1” every time the process of step S11 is performed. Then, the values at the time each lottery is performed are acquired by the start switch (SW) process in step S12 or the gate switch (SW) process in step S13, and in the special symbol process in step S14 or the normal symbol process in step S15. used. Note that a loop counter is used as the counter for performing the processing of step S1, and after reaching the set maximum value of the random number, it returns to “0” again.

  In the start port switch (SW) process (step S12), the game control unit 100 monitors the states of the first start port switch 111 and the second start port switch 112, and a detection signal is output from either switch. In addition, a process related to the hold number U1 for the first special symbol lottery and the hold number U2 for the second special symbol lottery, a process for obtaining random numbers (a jackpot random number, a symbol random number, a reach random number, and a variation pattern random number) are executed. Details of the start port switch process will be described later with reference to FIG.

  In the gate switch (SW) process (step S13), the game control unit 100 monitors the state of the gate switch 114. When the game ball passes through the gate 25 and a detection signal is output from the gate switch 114, it is normal. It is determined whether or not the number of symbols in the lottery is less than the upper limit. Then, when it is determined that the number of holds is less than the upper limit value, a normal symbol random number used for the normal symbol processing in step S15 is acquired.

  In the special symbol process (step S14), the game control unit 100 executes the special symbol lottery, displays the special symbol on the liquid crystal display 5 variably, and then stops and displays the special symbol indicating the result of the special symbol lottery. Execute the process. This special symbol process will be described in detail later based on FIG.

  In the normal symbol process (step S15), the game control unit 100 determines whether or not the normal symbol random number acquired in the gate switch process in step S13 matches the winning value. Then, after the normal symbol is variably displayed on the normal symbol display 45 (see FIG. 3) of the display device 4, the normal symbol indicating the determination result is stopped and displayed.

  In the special prize opening process (step S16), the game control unit 100 controls the opening / closing of the special prize opening 23 via the special prize opening control unit 116 when the special symbol lottery is won.

  In the electric tulip process (step S17), the game control unit 100 determines that the electric tulip 27 of the electric tulip 27 via the electric tulip opening / closing unit 113 when it is determined in the normal symbol process in step S15 that the normal symbol random number matches the winning value. A pair of blade members is operated. When the electric tulip 27 is operated, a game ball can be awarded to the second start port 22, and when the game ball wins the second start port 22, the second special symbol lottery is started.

  In the prize ball process (step S18), as described above, the game control unit 100 controls the number of game balls won and controls the payout of prize balls according to the prize.

  In the output process (step S19), the game control unit 100 sends to the effect control unit 130 various commands set in the RAM 103 and information necessary for the effect in the start port switch process in step S12 and the special symbol process in step S14. . In addition, a command instructing the payout of the prize ball set in the RAM 103 in the prize ball processing in step S18 is sent to the payout control unit 120.

[Configuration of RAM 103 of Game Control Unit 100]
Next, the configuration of the RAM 103 of the game control unit 100 will be described. FIG. 18 is a block diagram illustrating a configuration example of the RAM 103 of the game control unit 100. 18A shows the configuration of the storage area 109 and the reserved number storage unit 110 of the RAM 103, and FIG. 18B shows the configuration of the storage units 109A to 109H constituting the storage area 109.

  As illustrated in FIG. 18A, the RAM 103 includes a storage area 109 and a reserved number storage unit 110. The storage area 109 stores, for example, a jackpot random number or the like for up to eight reserved balls that can be held in the pachinko gaming machine 1, a first storage unit 109A, a second storage unit 109B, a third storage unit 109C, a fourth The storage unit 109D, the fifth storage unit 109E, the sixth storage unit 109F, the seventh storage unit 109G, and the eighth storage unit 109H are configured.

  As shown in FIG. 18B, these storage units 109A to 109H each store an area for storing the number of fluctuations N, an area for storing winning start information, an area for storing jackpot random numbers, and a design random number. A region for storing a reach random number, a region for storing a variation pattern random number, and a region for storing pre-determination information.

  The number of times of change N is information indicating the total number of special symbol lottery rights acquired by winning the game ball in the first start port 21 or the second start port 22. For example, after the power of the pachinko gaming machine 1 is turned on, a game ball wins the first starting slot 21 to acquire the first special symbol drawing right 50 times, and a game ball wins the second starting slot 22 When the right of the second special symbol lottery is acquired 10 times, “60”, which is the sum of the numbers of these rights, is stored in the third storage unit 109C, for example, as the number of changes N. Then, when the game ball wins further at the first starting port 21 from this state and acquires the right of special symbol lottery, “61”, which is obtained by adding “1” to “60”, is set as the number N of times of change, and the fourth storage unit 109D. Is remembered.

  In the case where a new game ball wins at the first start port 21 in a state where the number of hold of the game ball won at the first start port 21 reaches the maximum hold number Umax1 (“4” in the present embodiment). The number of fluctuations N is not counted, and a big hit random number or the like is not stored in the storage area 109. In addition, even when a new game ball wins the second start port 22 in a state where the hold number of the game balls won in the second start port 22 reaches the maximum hold number Umax2 (“4” in this embodiment). The number of fluctuations N is not counted and is not stored in the storage area 109 such as a big hit random number.

  The winning start information is obtained when the jackpot random number, the design random number, the reach random number, and the variation pattern random number stored in the same storage unit are obtained when the game ball wins the first starting port 21 or This is information indicating whether or not the game ball has been acquired when the second starting port 22 is won. These jackpot random numbers, design random numbers, reach random numbers, and variation pattern random numbers will be described in detail later.

  The pre-determination information is information obtained by a pre-determination process (see FIG. 21) described later based on the jackpot random number, the design random number, the reach random number, and the variation pattern random number. Specifically, the pre-judgment information is information indicating whether the winning start information, the special symbol lottery result is a big win, a small win, or a loss. Information indicating whether there is a small hit, information indicating what the type of the small hit is, if it is a loss, whether the production content is a production with reach or a production without reach Information indicating the variation pattern (variation time) of the special symbol, and information indicating the gaming state of the pachinko gaming machine 1 are included. The advance determination information is stored in the same storage unit as the jackpot random number, the design random number, the reach random number, the variation pattern random number, and the like that are the basis for generating the advance determination information.

  The seven types of information shown in FIG. 18B, the number of times of change N, the winning start information, the jackpot random number, the design random number, the reach random number, the change pattern random number, and the pre-determination information, Every time a game ball wins at the start port 22, the first storage unit 109A sequentially stores the game balls. For example, when no information is stored in any of the first storage unit 109A to the eighth storage unit 109H, seven pieces of information are stored in the first storage unit 109A. For example, when seven pieces of information are already stored in each of the first storage unit 109A to the fourth storage unit 109D, the seven pieces of newly acquired information are stored in the fifth storage unit 109E. . In addition, when the reserved ball that triggered the acquisition of the random number stored in the first storage unit 109A is digested, the seven pieces of information stored in the first storage unit 109A are discarded and each storage A process for shifting the information stored in the unit is performed. For example, in the case where seven pieces of information are stored in each of the first storage unit 109A to the third storage unit 109C, when the reserved ball corresponding to the information stored in the first storage unit 109A is digested, the first storage unit The information stored in unit 109A is discarded, the information stored in second storage unit 109B is moved to first storage unit 109A, and the information stored in third storage unit 109C is the second storage unit 109B. Moved to.

  The number-of-holds storage unit 110 shown in FIG. 18A stores the number of held U1 for the first special symbol lottery, the number of held U2 for the second special symbol lottery, and the number of held for the normal symbol lottery. The holding number U1 is appropriately updated by the CPU 101 at the timing when a game ball wins the first start port 21 or at the timing when the first special symbol lottery is performed. The number of holds U2 is appropriately updated by the CPU 101 at the timing when a game ball wins the second start port 22 or when the second special symbol lottery is performed. The holding number of the normal symbol lottery is appropriately updated by the CPU 101 at the timing when the game ball passes the gate 25 or the timing when the normal symbol lottery is performed.

[Start-up switch processing by game control unit 100]
FIG. 19 is a detailed flowchart of the start port switch process in step S12 of FIG. As shown in FIG. 19, the CPU 101 of the game control unit 100 receives a game ball in the first start port 21 based on the presence / absence of a detection signal from the first start port switch 111 and the first start port switch 111. Is determined to be "ON" (step S121). When the CPU 101 determines that the first start port switch 111 has been turned “ON” (step S121: YES), the CPU 101 reads out the maximum holding number Umax1 of the first special symbol lottery from the ROM 102, and stores it in the holding number storage unit 110. It is determined whether or not the stored number U1 of the first special symbol lottery is less than the maximum number of reservations Umax1 (step S122).

  When the CPU 101 determines that the hold number U1 is less than the maximum hold number Umax1 (step S122: YES), the CPU 101 updates the value of the hold number U1 stored in the hold number storage unit 110 by adding “1” (step S122: YES). Step S123). Then, “1” is added to the number of fluctuations N newly stored in the storage area 109 (step S124).

  The CPU 101 receives the winning start opening information indicating the first starting opening 21 and the number of fluctuations N updated in the process of step S124, along with the random numbers for the first special symbol lottery held by the process of step S123 (big hit random numbers, symbol random numbers). , Reach random number, and fluctuation pattern random number) are acquired and stored in the storage area 109 (step S125). Then, the CPU 101 performs a pre-determination process to be described later using the random number stored in the storage area 109 in the process of step S125 (step S126).

  When it is determined that the first start port switch 111 is “OFF” (step S121: NO), when it is determined that the hold number U1 is equal to the maximum hold number Umax1 (step S122: NO), or in step S126 When the pre-determination process is performed, based on the presence or absence of a detection signal from the second start port switch 112, the CPU 101 wins a game ball in the second start port 22 and the second start port switch 112 is “ON”. It is determined whether or not (step S127). When the CPU 101 determines that the second start port switch 112 has been turned “ON” (step S127: YES), the CPU 101 reads the maximum reserved number Umax2 of the second special symbol lottery from the ROM 102, and is stored in the reserved number storage unit 110. It is determined whether or not the holding number U2 of the second special symbol lottery is less than the maximum holding number Umax2 (step S128).

  When the CPU 101 determines that the hold number U2 is less than the maximum hold number Umax2 (step S128: YES), the CPU 101 updates the value of the hold number U2 stored in the hold number storage unit 110 by adding “1” (step S128: YES). Step S129). Then, “1” is added to the number of fluctuations N newly stored in the storage area 109 (step S130).

  The CPU 101 receives the winning start opening information indicating the second starting opening 22 and the number of fluctuations N updated in the process of step S130, as well as the random numbers (big hit random numbers, symbol random numbers) for the second special symbol lottery held by the process of step S129. , Reach random number, and fluctuation pattern random number) are acquired and stored in the storage area 109 (step S131). Then, the CPU 101 performs a pre-determination process using the random number stored in the storage area 109 in the process of step S131 (step S132). The advance determination process in step S132 is performed in the same manner as the advance determination process in step S126.

  On the other hand, when it is determined that the second start port switch 112 is “OFF” (step S127: NO), when it is determined that the hold number U2 is equal to the maximum hold number Umax2 (step S128: NO), or step When the advance determination process of S132 is performed, the start port switch process ends, and the process proceeds to the gate switch process in step S13 of FIG.

[Judgment method using random numbers]
Next, a determination method using random numbers in the advance determination process (see FIG. 21) and the jackpot determination process in step S147 (see FIG. 22) described later will be described. FIG. 20 is a diagram illustrating a configuration example of random numbers used in the advance determination process and the jackpot determination process. FIG. 20A shows an example of a jackpot random number. FIG. 20B shows an example of a design random number at the time of jackpot due to the first start opening prize, FIG. 20C shows an example of a design random number at the time of jackpot by the second start opening prize, FIG. ) Shows an example of a design random number at the time of small hit. FIG. 20E shows an example of a reach random number.

  As shown in FIG. 20 (A), the jackpot random number is different for each of the cases where the pachinko gaming machine 1 is in a low probability state and a high probability state where the winning probability of the special symbol lottery is relatively low. Is set to The range that the jackpot random number can take is “0” to “600” in any gaming state. In addition, two types of jackpot random numbers are set for each of a low probability state and a high probability state, that is, a jackpot and a jackpot. That is, as a random number determination table, a low probability random number determination table used for determining a jackpot random number in a low probability state and a high probability random number determination table used for determining a jackpot random number in a high probability state are prepared. Yes.

  As for the low probability state, two jackpot winning values (“7” and “317”) are set, so the jackpot winning probability in the low probability state is 2/601, which was acquired in the low probability state When the jackpot random number is “7” or “317”, the jackpot is determined. Regarding the low-probability state, two small winning winning values (“50” and “100”) are set, so the small-winning winning probability in the low-probability state is 2/601, which is acquired in the low-probability state. When the hit jackpot random number is “50” or “100”, it is determined as a jackpot.

  With regard to the high probability state, 20 jackpot winning values (“7”, “37”, “67”,..., “517”, “547”, “577”) are set. The jackpot winning probability is 20/601. If the jackpot random number acquired in the high probability state matches any of these 20 winning values, the jackpot is determined. With respect to the high probability state, two small winning values (“50” and “100”) are set, so the small winning winning probability in the high probability state is 2/601, which is acquired in the high probability state. When the big hit random number is “50” or “100”, it is determined that the jackpot is a small hit.

  Here, when “small hit” is determined to be a small hit, for example, a small hit game in which the opening / closing of the big winning opening 23 is performed twice is executed, and the game state at the time of winning the small hit is also after the small hit game ends. It is a hit. For this reason, if the gaming state at the time of winning the small hit is, for example, the probability variation gaming state, the gaming state is not shifted and the probability variation gaming state is continued even after the end of the small hitting game. Also, if the gaming state at the time of winning the small hit is, for example, the normal gaming state, the gaming state does not shift and the normal gaming state is continued even after the small hitting game ends.

  With respect to one jackpot, in this embodiment, “2” jackpot winning values for the low probability state are set, whereas “20” jackpot winning values for the high probability state are set. For this reason, the probability that the game ball wins the first start port 21 or the second start port 22 in the high probability state and the special symbol lottery is performed and the big win is the first start port 21 or the second in the low probability state. The game ball is won at the starting port 22 and a special symbol lottery is performed, which is ten times the probability of winning a jackpot.

  When the result of the first special symbol lottery is a big hit, the following determination process regarding the symbol random number is performed. As shown in FIG. 20 (B), the types of jackpots based on the first start opening prize are as follows: per length with high probability, short per length, short per length with high probability, short per short with high probability, short per short with normal time, high probability There are six types available, one for each short time and one for normal and one for short time. The range that can be taken by the design random number acquired when a game ball wins the first starting port 21 is “0” to “250”. Since 101 winning values of “0” to “100” are assigned per length with high probability, the length per length with high probability is 101/251. Further, since 50 winning values of “101” to “150” are assigned per length with a normal time shortening, it is per length with a normal time shortening with a probability of 50/251. In addition, “151” to “175”, “176” to “200”, “201” for short per short with high probability, per short with normal time, per short length with high probability, and per short without normal time. Since the winning values of “225” and “226” to “250” are respectively assigned, the probability is 25/251 for any winning.

  When the result of the second special symbol lottery is a big hit, the following determination process regarding the symbol random number is performed. As shown in FIG. 20C, there are two types of jackpots for the second start-up winnings, one per length with a high probability and a length with a normal time. The possible range of symbol random numbers acquired when a game ball wins the second starting port 22 is “0” to “250”. Since 151 winning values of “0” to “150” are assigned per length with high probability, the length per length with high probability is 151/251. Since 100 winning values of “151” to “250” are assigned per length with a normal time / short time, it is per length with a normal time / short with a probability of 100/251.

  As described above, if the big hit random number acquired when the game ball wins the first start opening 21 or the second start opening 22 is “50” or “100”, it is determined that the big hit. As shown in FIG. 20D, two types of small hits A and small hits B are prepared as the types of small hits. The range of the design random number at the time of small hit is “0” to “250”. With respect to the small hit A, 121 winning values of “0” to “120” are assigned, so the small hit A has a probability of 121/251. With respect to one small hit B, since 130 winning values of “121” to “250” are assigned, the small hit B is 130/251. Note that the small hit A and the small hit B have the same contents of the small hit game executed thereafter, and are displayed on the first special symbol display 41 or the second special symbol display 42 of the display 4. Only the special symbol is different.

  When the result of the special symbol lottery is a loss, the following determination process regarding reach random numbers is performed. As shown in FIG. 20E, the reachable range of reach random numbers is “0” to “250”, and a reach random number determination table is prepared for each of the cases with and without reach. Regarding reach, since 25 reach random numbers “0” to “24” are assigned, reach is achieved with a probability of 25/251. Further, with respect to the absence of reach, 226 reach random numbers “25” to “250” are assigned, and therefore no reach is achieved with a probability of 226/251. More specifically, the reach random number is determined based on the reach random number determination table only when it is determined that the result of the special symbol lottery is a loss (does not correspond to any winning value shown in FIG. 20A). Is determined. As described above, at the time of losing, the probability that an effect without reach is increased, while a so-called gas reasure effect that gives a player a sense of expectation is executed with a probability of about 10%. On the other hand, since the reach presence effect is always executed at the time of big hit and small hit, in this case, the reach random number is acquired, but the determination on the reach random number is not performed.

  In the case of winning the jackpot, there will always be a production with reach, and finally a special symbol with three identical numbers on a horizontal or diagonal line will be displayed on the LCD screen as a result of the special symbol lottery. 50. On the other hand, in the case of winning with a small win or loss, the special symbol is stopped and displayed in a state where only two identical numbers are aligned on the straight line and the third is not aligned.

[Preliminary determination processing by game control unit 100]
Hereinafter, the prior determination process performed by the game control unit 100 will be described with reference to FIG. Here, FIG. 21 is a detailed flowchart of the preliminary determination process in steps S126 and S132 of FIG.

  After the process of step S125 or the process of step S131 in FIG. 19 is performed, the CPU 101 of the game control unit 100 determines that the gaming state of the pachinko gaming machine 1 is in a high probability state based on the gaming state information stored in the RAM 103. It is determined whether or not it is a probability variation gaming state or a latent gaming state in this embodiment (step S1261). When the CPU 101 determines that the state is a high probability state (step S1261: YES), the special symbol lottery number of times after the right of the special symbol lottery acquired by the start-up switch process shifts to the current high probability state. It is determined whether it is equivalent to the right. In other words, if the winning of the jackpot (per length with high probability short-time, short per short with high probability short-time or short per short without high-probability time short) is determined when the gaming state becomes a high probability state, the number of changes N when winning the jackpot is The reference number M is set. For example, in the case of winning by the special symbol lottery of the 200th time since the power of the pachinko gaming machine 1 is turned on, for example, per winning length with high probability, data “200” is stored in the RAM 103, and accordingly, The internal state becomes a high probability state. Therefore, the special symbol lottery performed at the 201st time since the power-on of the pachinko gaming machine 1 corresponds to the first special symbol lottery after shifting to the high probability state, and the special symbol lottery performed at the 210th time is a high probability. This corresponds to the 10th special symbol lottery after the transition to the state. In this way, the special symbol lottery right acquired by the start port switch process is calculated to correspond to the number of special symbol lotteries after the transition to the high probability state. Specifically, the CPU 101 subtracts the reference number M from the variation number N to obtain the calculated value L (step S1262).

  Then, the CPU 101 determines whether or not the calculated value L is equal to or less than the predetermined number X (step S1263). Here, the predetermined number X is an upper limit number of times that the big hit random number is determined based on the high probability random number determination table (see FIG. 20A). In the present embodiment, when a jackpot where the gaming state becomes a high probability state is won, the subsequent jackpot random number determination is performed based on the high probability random number determination table with the upper limit being 100 times. Accordingly, the predetermined number X is set to “100” in the present embodiment. Therefore, in the present embodiment, in step S1263, the CPU 101 determines whether or not the calculated value L is “100” or less. That is, whether the jackpot random number acquired by the start port switch process is determined based on the high probability random number determination table, or whether the high probability state ends and is determined based on the low probability random number determination table Is determined in step S1263.

  For example, it is assumed that the short win with a high probability time is won by the 200th special symbol lottery (the number of fluctuations N = 200) after the power of the pachinko gaming machine 1 is turned on. After that, the 98th special symbol lottery is executed after becoming a high probability state, and the variation number N = 299 hold A, the variation number N = 300 hold B, the variation number N in a state where the jackpot has not been won yet. It is assumed that information regarding the hold C = 301 is stored in the storage area 109. In this case, since the reference number M is set to “200”, the calculated value L for the hold A is “99”, the calculated value L for the hold B is “100”, and the calculated value L for the hold C is “101”. " Accordingly, the hold A and the hold B are determined as “YES” in step S1263, and the hold C is determined as “NO” in step S1263.

  When the CPU 101 determines that the calculated value L is equal to or smaller than the predetermined number of times X (step S1263: YES), the prior determination information related to the jackpot for changing the subsequent gaming state to the low probability state is displayed before the start port switch process is started. It is determined whether or not it is stored in the storage area 109 (step S1264). For example, when a random number is stored in the fifth storage unit 109E (see FIG. 18) in step S125 (see FIG. 19) of the start port switch process, the first storage unit 109A stores the random number in the fourth storage unit 109D. Then, it is determined whether or not pre-determination information relating to either the normal short / short short hit or the normal short / short short hit is stored. That is, it is determined whether or not there is a holding ball that is digested prior to the holding ball that is held in the start-up switch processing, so that the gaming state is shifted from the high probability state to the low probability state. Because, when such a holding ball is put on hold first, even if it is in a high probability state when the holding ball is put on hold in the start-up switch processing, it is in a low probability state when digesting the holding ball. Because it becomes. Therefore, when the CPU 101 determines that the previous hold is not normally hit (step S1264: NO), the CPU 101 selects the high-probability random number determination table (step S1266) and determines that the previous hold has a normal hit. If so (step S1264: YES), the low probability random number determination table is selected (step S1267).

  On the other hand, when the current gaming state of the pachinko gaming machine 1 is a low probability state (normal gaming state or short-time gaming state) (step S1261: NO), or when the calculated value L exceeds the predetermined number X (step S1263) : NO), the CPU 101 determines whether or not the prior determination information relating to the jackpot for changing the subsequent gaming state to the high probability state is stored in the storage area 109 before the start port switch process is started (step S1265). . For example, when a random number is stored in the sixth storage unit 109F (see FIG. 18) in step S125 (see FIG. 19) of the start port switch process, the first storage unit 109A to the fifth storage unit 109E per length with high probability shortening Then, it is determined whether or not pre-determination information related to either a short hit with a high probability short time or a short hit without a high probability short time is stored. That is, it is determined whether or not there is a holding ball that is digested prior to the holding ball that is held in the start-up switch process, and that shifts the gaming state from the low probability state to the high probability state. Because, when such a holding ball is put on hold first, even if it is in a low probability state when the holding ball is put on hold by the start-up switch processing, it is in a high probability state when digesting the holding ball. Because it becomes. Therefore, if the CPU 101 determines that the previous hold does not have a high probability (step S1265: NO), the CPU 101 selects the low probability random number determination table (step S1267), and the previous hold has a high probability. (Step S1265: YES), the high probability random number determination table is selected (step S1266).

  In addition, in the storage area 109 (see FIG. 18), prior determination information related to a jackpot for changing a subsequent gaming state to a high probability state and prior determination information related to a jackpot for changing a subsequent gaming state to a low probability state are stored. If stored, the process of step S1264 or step S1265 is performed based on the preliminary determination information corresponding to the reserved ball to be digested later among these two preliminary determination information. For example, when the first storage unit 109A stores pre-determined information related to the length with a high probability of shortening the time, and the third storage unit 109C stores pre-determined information related to the length of the normal time-shortened length, the third storage unit Determination is performed based on the prior determination information stored in 109C. In contrast to this example, “YES” is determined when the process of step S1264 is performed, and “NO” is determined when the process of step S1265 is performed.

  In this way, by performing the processing of step S1261 to step S1265, not the internal state of the pachinko gaming machine 1 when the game ball wins the first starting port 21 or the second starting port 22, but during the special symbol processing ( Based on the internal state (at the time of holding ball digestion), it becomes possible to make a jackpot pre-determination when the game ball wins the first start port 21 or the second start port 22. Therefore, even if the gaming state changes from the high probability state to the low probability state before the reservation ball digestion, or conversely, the gaming state changes from the low probability state to the high probability state, It is possible to derive a preliminary determination result of symbol lottery).

  Following the processing of step S1266 or step S1267, the CPU 101 determines each random number based on the selected table among the high probability random number determination table and the low probability random number determination table (step S1268). Specifically, the CPU 101 determines that the jackpot random number acquired in step S125 or step S131 is based on the random number determination table (see FIG. 20A) selected in step S1266 or step S1267. It is determined whether the symbol lottery result is a big hit, a small win, or a loss. When the CPU 101 determines that the jackpot is a jackpot, the type of jackpot is stored in a symbol random number stored in the same storage unit as the jackpot random number and a random number determination table (see FIGS. 20B and 20C). Judgment based on. In addition, when it is determined that the game is a small hit, the type of the small hit is determined based on the design random number and the random number determination table (see FIG. 20D). On the other hand, when the jackpot random number is determined to be lost without corresponding to any of the random value (winning value) stored in the high probability random number determination table and the low probability random number determination table of FIG. Based on the reach random number stored in the same storage unit as the jackpot random number and the symbol random number, and the random number determination table (see FIG. 20E), the CPU 101 reaches during the special symbol variation display for the game ball determined to be lost. It is determined whether to perform an effect with or without reach.

  By the way, as is clear from the notation of FIG. 19, the prior determination process in the present embodiment is not when the special symbol variation display is started, but the game ball wins at the first start port 21 or the second start port 22. Is done when. That is, the CPU 101 executes a special symbol lottery at the timing when a winning of a game ball is detected, and determines the type of jackpot if it is determined to be a jackpot as described above, and if it determines that the jackpot is determined, The type of small hit is determined, and when it is determined that the game is lost, it is determined whether an effect with reach or an effect without reach is performed. Based on the variation pattern random number stored in the same storage unit as the jackpot random number, the design random number, and the reach random number, the variation pattern of the special design that is variably displayed on the liquid crystal display 5 when the reserved ball is digested is determined.

  Subsequently, the CPU 101 generates pre-determination information including information indicating the determination result in step S1268 (step S1269). This prior determination information is stored in the storage unit 109 in the same storage unit in which the jackpot random number, symbol random number, reach random number, and variation pattern random number used in the determination in step S1268 are stored.

  After generating the advance determination information, the CPU 101 includes the advance determination information generated in the process of step S1269 in order to instruct the effect control unit 130 to additionally display the hold display image on the liquid crystal display 5. The command is set (stored) in the RAM 103 (step S1270). The hold command is transmitted to the effect control unit 130 when the CPU 101 executes the output process in step S19 of FIG.

  As will be described in detail later, the effect control unit 130 causes the image sound control unit 140 to execute a process of additionally displaying the hold display image on the liquid crystal display 5 based on the hold command including the prior determination information, The image sound control unit 140 and the lamp control unit 150 are caused to execute a pre-reading effect, which is an effect of notifying that the reliability that is a big hit at the time of digestion is high.

[Special symbol processing by game control unit 100]
FIG. 22 is a detailed flowchart of the special symbol process in step S14 of FIG. As shown in FIG. 22, the CPU 101 of the game control unit 100 determines whether or not the current state of the pachinko gaming machine 1 is a big hit based on information stored in the RAM 103 (step S141). . If it is determined by the CPU 101 that the jackpot is being hit (step S141: YES), the special symbol representing some jackpot has already been selected and stopped and displayed. The symbol process is terminated, and the process proceeds to the normal symbol process in step S15 (see FIG. 17).

  If the CPU 101 determines that the jackpot is not being won (step S141: NO), the CPU 101 determines whether or not the special symbol is being changed (step S142). When the CPU 101 determines that the special symbol variation display is not being performed (step S142: NO), the number of holds U2 stored in the number-of-holds storage unit 110 (see FIG. 18A) is “1” or more. Is determined (step S143). When the CPU 101 determines that the hold number U2 is “1” or more (step S143: YES), the CPU 101 rewrites the hold number U2 stored in the hold number storage unit 110 to a value obtained by subtracting “1” (step S144). .

  When the CPU 101 determines that the hold number U2 is not equal to or greater than “1” (the second special symbol lottery is not held) (step S143: NO), the hold number U1 stored in the hold number storage unit 110 is It is determined whether or not “1” or more (step S145). When the CPU 101 determines that the hold number U1 is “1” or more (step S145: YES), the CPU 101 rewrites the hold number U1 stored in the hold number storage unit 110 to a value obtained by subtracting “1” (step S146). . On the other hand, when the CPU 101 determines that the number of held U1 is not equal to or greater than “1” (the first special symbol lottery is not held) (step S145: NO), the special symbol is not started without starting the variable symbol display. The process ends, and the process proceeds to the normal symbol process in step S15.

  The CPU 101 executes jackpot determination processing after performing the processing of step S144 or step S146 (step S147). Specifically, when the process of step S147 is executed following the process of step S144, the winning value (see FIG. 20A) stored in the ROM 102 is read into the RAM 103. Then, the oldest jackpot random number (the first jackpot random number stored first) among the jackpot random numbers acquired in response to the winning of the game ball at the second starting port 22 and stored in the storage area 109 (see FIG. 18) is Whether the result of the second special symbol lottery is a jackpot, a jackpot or a loss is determined based on whether or not it matches any of the jackpot winning values.

  On the other hand, when the process of step S147 is executed following the process of step S146, the CPU 101 reads the jackpot winning value (see FIG. 20A) stored in the ROM 102 into the RAM 103. Then, the oldest jackpot random number (the first jackpot random number stored first) among the jackpot random numbers acquired in response to the winning of the game ball at the first start port 21 and stored in the storage area 109 (see FIG. 18) is obtained. Whether the result of the first special symbol lottery is a jackpot, a jackpot or a loss is determined based on whether or not it matches any of the jackpot winning values.

  When it is determined that the result of the second special symbol lottery or the first special symbol lottery is a big hit, the CPU 101 wins the winning values of the symbol random numbers assigned to the respective types of jackpots from the ROM 102 (FIG. 20B and ( C) is read into the RAM 103. Then, the type of jackpot is determined based on which symbol random number stored in the same storage unit as the jackpot random number used for the lottery determined to be a jackpot matches the winning value of which symbol random number. At that time, when it is determined that the result of the second special symbol lottery is a big hit, the type of jackpot is determined using the winning value illustrated in FIG. 20C, and the result of the first special symbol lottery is the big hit If it is determined that the jackpot type is determined, the winning type is determined using the winning value illustrated in FIG.

  When it is determined that the result of the second special symbol lottery or the first special symbol lottery is a small hit, the CPU 101 assigns a small random number at the time of the small hit assigned to each of the small hit A and the small hit B from the ROM 102. The winning value (see FIG. 20D) is read out to the RAM 103. Based on whether the symbol random number stored in the same storage unit as the jackpot random number used for the lottery determined to be a small hit matches the winning value for the small hit A or the winning value for the small hit B , Determine the type of small hits.

  When the CPU 101 determines that it is a jackpot, it sets (stores) the jackpot symbol corresponding to the type of jackpot in the RAM 103 as setting information. If it is determined that the game is a small hit, a small hit symbol corresponding to the type of the small hit is set in the RAM 103 as setting information. If it is determined that the game is lost, a lost symbol indicating that the result of the special symbol lottery is lost is set in the RAM 103 as setting information.

  The CPU 101 executes the variation pattern selection process after setting the jackpot symbol, the small bonus symbol, or the lost symbol as setting information by the process of step S147 (step S148). Specifically, when the jackpot symbol is set in step S147, the variation pattern table for jackpot is read from the ROM 102 and set in the RAM 103, and when the jackpot symbol is set, the variation pattern table for jackpot is set. Is read from the ROM 102 and set in the RAM 103.

  On the other hand, when the lost symbol is set in the process of step S147, the CPU 101 reads the reach random number (see FIG. 20E) stored in the ROM 102 into the RAM 103. Based on which reach random number stored in the same storage unit as the jackpot random number and symbol random number used in the jackpot determination process in step S147 matches with the reach random number read from the ROM 102, Decide whether or not to perform reach production to expect a big hit. When it is determined that the reach effect is to be performed (the effect with reach is performed), the variation pattern table for reach is read from the ROM 102 and set in the RAM 103, and it is determined that the reach effect is not performed (the effect without reach is performed). In this case, the variation pattern table for loss is read from the ROM 102 and set in the RAM 103. Here, the variation pattern table is a table in which a plurality of variation patterns (variation times 10 seconds, 30 seconds, 60 seconds, 90 seconds, etc.) prepared in advance are associated with random numbers of variation pattern random numbers.

  Next, the CPU 101 refers to the set variation pattern table and selects a variation pattern corresponding to the variation pattern random number stored in the same storage unit as the jackpot random number and symbol random number used in the jackpot determination process in step S147. Thus, the variation pattern (variation time) of the special symbol is determined. The variation pattern of the special symbol determined in this way is set in the RAM 103 as setting information.

  After performing the jackpot determination process in step S147 and the variation pattern selection process in step S148, the CPU 101 starts variation including the symbol setting information set in the jackpot determination processing and the variation pattern setting information set in the variation pattern selection processing. A command is generated and set in the RAM 103 (step S149). This variation start command is transmitted to the effect control unit 130 when the CPU 101 executes the output process in step S19 (see FIG. 17). Thereby, the variable display of the special symbol in the liquid crystal display 5 is started. The change start command includes game state information indicating the game state of the pachinko gaming machine 1 in addition to symbols and change patterns.

  After setting the variation start command, the CPU 101 starts the variation display of the special symbol on the first special symbol display 41 or the second special symbol display 42 of the display 4 based on the setting information set in the RAM 103 ( Step S150), the measurement of the fluctuation time, which is the elapsed time from the time when the special symbol fluctuation display is started, is started (Step S151). Note that the special symbol change display started in the process of step S150 is performed using the second special symbol display 42 when the process is performed subsequent to the process of step S144, and is performed following the process of step S146. The first special symbol display 41 is used in the case where the first special symbol display 41 is used.

  Next, when the CPU 101 starts measuring the variation time by the process of step S151, or when determining that the special symbol variation is being displayed (step S142: YES), from the start of the variation time measurement in step S151, It is determined whether or not the variation time corresponding to the variation pattern set in the variation pattern selection process in step S148 has elapsed (step S152). If the CPU 101 determines that the variation time has not elapsed (step S152: NO), the special symbol process is terminated, and the process proceeds to the normal symbol process in step S15 (see FIG. 17).

  On the other hand, if the CPU 101 determines that the variation time has elapsed (step S152: YES), the CPU 101 sets a variation stop command in the RAM 103 (step S153), and the first special symbol display 41 or the first symbol display unit 41 started in the process of step S150. 2 The special symbol change display by the special symbol display 42 is terminated (step S154). By the processing in step S154, the special symbol indicating the result of the special symbol lottery is stopped and displayed on the first special symbol display 41 or the second special symbol display 42. Following the stop of the special symbol fluctuation display, the CPU 101 resets the fluctuation time stored in the RAM 103 (step S155). The change stop command set in the process of step S153 is transmitted to the effect control unit 130 by the CPU 101 executing the output process in step S19 (see FIG. 17). As a result, the special symbol variation display performed on the liquid crystal display 5 is ended, and the special symbol indicating the result of the special symbol lottery is stopped and displayed.

  When the CPU 101 resets the variation time and determines that it is a jackpot, the CPU 101 opens or closes the jackpot 23 via the jackpot control unit 116 (see FIG. 11) or the result of the jackpot determination process in step S147. Then, the stop process such as changing the gaming state of the pachinko gaming machine 1 is executed (step S156). After this stop process, the process proceeds to the normal symbol process in step S15 (see FIG. 17).

[Production control processing by production control unit 130]
When the power of the pachinko gaming machine 1 is turned on, the CPU 131 of the effect control unit 130 executes a pre-reading effect execution random number for determining whether or not to execute a pre-reading effect based on the hold display image, or when the reserved ball is digested Random number update processing for updating various random numbers such as effect random numbers used for determining the content of the game effect to be executed is repeatedly executed. That is, the effect control unit 130 executes the effect control process described below while repeating the random number update process while the pachinko gaming machine 1 is activated.

  Hereinafter, the effect control process performed by the effect control unit 130 will be described with reference to FIGS. 23 to 26. Here, FIG. 23 and FIG. 24 are flowcharts illustrating an example of the effect control process performed by the effect control unit 130. FIG. 25 and FIG. 26 are explanatory diagrams for explaining the two-screen display by the liquid crystal screen 50 and the EL screen 60. Note that the processing performed by the effect control unit 130 described based on the flowcharts of FIG. 23 and FIG. 24 and thereafter is performed according to a command issued by the CPU 131 based on a program stored in the ROM 132.

  The CPU 131 of the effect control unit 130 determines whether or not the hold command set in the process of step S1270 of FIG. 21 has been received (step S201). If the CPU 131 determines that a hold command has not been received (step S201: NO), the process proceeds to step S211 described later.

  If the CPU 131 determines that a hold command indicating that a game ball has won is received at the first start port 21 or the second start port 22 (step S201: YES), the pre-reading effect lottery process at step S206, which will be described later, is performed. The pre-reading effect execution random number used and the effect random number used in the effect determining process in step S216, which will be described later, are acquired and stored in the RAM 133 (step S202). As described above, the pre-reading effect execution random number and the effect random number are each incremented by “1” each time the random number update process is performed, and the count value at the time when the hold command is received by the CPU 131 is the pre-reading effect execution random number and Acquired as a production random number. Note that the advance determination information included in the hold command received by the CPU 131 is temporarily stored in the RAM 133.

  When the pre-reading effect execution random number and the effect random number are acquired, the CPU 131 adds “1” to the value of the hold number stored in the RAM 133 and updates it (step S203). Specifically, winning start information is extracted from the pre-determination information included in the received hold command, and based on the winning start information, whether the first special symbol lottery has been put on hold or the second special symbol Determine if the lottery has been put on hold. When it is determined that the first special symbol lottery is held, the value of the number of the first special symbol lottery is updated by adding “1”, and when it is determined that the second special symbol lottery is held. The value of the number of holdings in the second special symbol lottery is updated by adding “1”.

  Next, the CPU 131 determines whether or not to execute a pre-reading effect lottery process (step S204). Specifically, the CPU 131 determines whether or not the hold indicated by the hold command is a lottery object for determining whether to perform the pre-reading effect, based on the prior determination information extracted from the hold command. . As this determination method, any one of information indicating that the result of the special symbol lottery is a big hit or a small win and information indicating that the effect content is an effect with reach is included in the prior determination information. In this case, it is determined that the pre-reading effect lottery process is executed, and when neither information is included in the pre-determination information, that is, the information indicating that the result of the special symbol lottery is lost and the content of the effect is a reachless effect. There is a method of determining that the pre-reading effect lottery process is not executed when information indicating that the pre-determination information is included. However, the determination method in step S204 is not limited to this. For example, the determination may be performed in consideration of the content of the hold that has already been put on hold.

  When it is determined that the pre-reading effect lottery process is not executed (step S204: NO), the CPU 131 transmits a normal hold command to the image sound control unit 140 (step S205). When this normal hold command is received by the image sound control unit 140, the CPU 141 of the image sound control unit 140 sends a control signal instructing execution of a process for displaying the hold display image in the normal display mode on the liquid crystal display 5. Output to VDP142. On the other hand, the drawing engine 1424 of the VDP 142 reads the hold display image in the normal display mode from the image ROM 148, draws the main image including the hold display image as a part of the display content in the VRAM_FB 1426, and outputs the output circuit 1427. Is output to the liquid crystal display 5.

  When the CPU 131 determines to execute the prefetch effect lottery process (step S204: YES), the winning value used for the prefetch effect lottery process is read from the ROM 132, and the prefetch effect execution random numbers acquired in the process of step S202 are these. Whether or not to execute the pre-reading effect is determined based on whether or not it matches any of the winning values (step S206).

  If the prefetch effect execution random number acquired in the process of step S202 does not match any winning value and the CPU 131 determines that the prefetch effect is not executed (step S207: NO), the process proceeds to step S205. . As a result, as in the case where “NO” is determined in the step S204, the hold display image without the pre-reading effect is additionally displayed on the liquid crystal screen 50.

  On the other hand, when the CPU 131 determines that the prefetch effect execution random number acquired in the process of step S202 matches any winning value and executes the prefetch effect (step S207: YES), the special hold command is subjected to image acoustic control. It transmits to the part 140 (step S208). When this special hold command is received by the image sound control unit 140, the CPU 141 of the image sound control unit 140 displays a hold display image in a special display mode (for example, a color different from the normal hold display image) on the liquid crystal display. A control signal for instructing execution of processing to be displayed on the device 5 is output to the VDP 142. On the other hand, the drawing engine 1424 of the VDP 142 reads a reserved display image having a special display mode from the image ROM 148, draws a main image including the reserved display image as a part of display contents on the VRAM_FB 1426, and outputs the output circuit 1427. Is output to the liquid crystal display 5. A special hold command is also transmitted to the lamp control unit 150, and sound output from the speaker 35, the panel lamp 8 and the frame are accompanied with a pre-reading effect in which a hold display image in a special display mode is displayed on the liquid crystal screen 50. You may make it perform the prefetch effect by light emission of the lamp | ramp 36. FIG.

  When the process of step S205 is performed, when the process of step S208 is performed, or when “NO” is determined in step S201, the CPU 131 is based on, for example, information on the effect acquired from the image sound control unit 140. Then, it is determined whether or not an effect accompanied by a special symbol variation display is being executed (step S211). If it is determined that the effect with the special symbol variation display is not being executed (step S211: NO), the CPU 131 determines whether or not the variation start command set in the process of step S149 in FIG. 22 has been received. (Step S212).

  If it is determined that the change start command has been received (step S212: YES), the CPU 131 updates the pending number stored in the RAM 133 by subtracting “1” (step S213). Specifically, based on the setting information included in the change start command received from the game control unit 100, the start of the production related to the first special symbol lottery that was on hold was instructed or was on hold It is determined whether the start of the production related to the second special symbol lottery has been instructed. When it is determined that the start of the effect related to the first special symbol lottery has been instructed, the number of holdings of the first special symbol lottery is updated by subtracting “1”, and the start of the effect related to the second special symbol lottery is instructed. If it is determined that it has been, the number of holdings of the second special symbol lottery is updated by subtracting “1”.

  After updating the number of holds in the process of step S213, the CPU 131 transmits a hold digest command for instructing erasure of the hold display image displayed on the liquid crystal screen 50 to the image sound control unit 140 (step S214). This reserved digest command includes information indicating whether the reserved ball related to the first special symbol lottery is digested or whether the reserved ball related to the second special symbol lottery is digested. The CPU 141 of the image sound control unit 140 that has received the reserved digest command deletes the reserved display image related to the first special symbol lottery or the reserved display image related to the second special symbol lottery from the liquid crystal screen 50 based on the reserved digest command.

  By the way, the hold command transmitted from the game control unit 100 includes advance determination information. After transmitting the pending digest command, the CPU 131 reads out prior determination information corresponding to the retained ball to be digested this time, and based on the prior determination information from a plurality of performance tables (not shown) stored in the ROM 132. 1 effect table is selected (step S215).

  The ROM 132 of the effect control unit 130 stores a long hit effect table, a short hit and small hit effect table, an effect table with lose reach, and an effect table without lose reach. Each of these effect tables is provided with a plurality of tables corresponding to the variation pattern (variation time) determined by the game control unit 100. For example, there is a table for 4 seconds, 8 seconds, and 12 seconds in the effect table without los-reach, and a table for 1 minute, 1 minute 30 seconds, and 2 minutes is provided in the long hit effect table. It has been. The CPU 131 selects one table from the plurality of tables based on information included in the advance determination information. For example, when the prior determination information includes information indicating “losing”, information indicating that “reaching-free production” is performed, and information indicating that “variation time” is 4 seconds, the CPU 131 Select the no-lack reach production table.

  When the effect table is selected, the CPU 131 functioning as the effect determining means determines the contents of the game effect to be performed during the special symbol variation display (step S216). Specifically, the effect table selected in the process of step S215 is an effect in which an effect random number and an effect pattern are associated with each other, and the CPU 131 stores a large number stored in the effect table selected in the process of step S215. An effect pattern corresponding to the effect random number acquired in step S202 is read out from the effect patterns. Thereby, the variation pattern of the special symbol displayed on the liquid crystal screen 50, the operation pattern and the light emission pattern of the movable accessory 7, the light emission pattern of the panel lamp 8 and the frame lamp 36, the output pattern of the sound output from the speaker 35, etc. Alternatively, a plurality of game effects are determined. The content of the display effect performed on the liquid crystal screen 50 is determined by the process of step S216.

  The CPU 131 transmits an effect start command for instructing the start of the determined game effect to the image sound control unit 140 and the lamp control unit 150 (step S217). On the other hand, the CPU 141 of the image sound control unit 140 outputs a control signal instructing execution of a display effect including a variable symbol display according to the received effect start command to the VDP 142, and the drawing engine 1424 of the VDP 142 The material data necessary for executing the display effect instructed by the control signal is read from the image ROM 148 and stored in the VRAM_RS 1425, and the main image is drawn on the VRAM_FB 1426 based on the material data, via the output circuit 1427. Output to the liquid crystal display 5. As a result, a display effect with a special symbol variation display on the liquid crystal screen 50, that is, one-screen display by the liquid crystal screen 50 is started. In addition, the CPU 151 of the lamp control unit 150 operates the movable accessory 7, the panel lamp 8, and the frame lamp 36 with an operation pattern and a light emission pattern corresponding to the received effect start command. Thereby, the effect by the sound and light interlocked with the display effect performed on the liquid crystal screen 50 is performed.

  When the process of step S217 is performed, or when it is determined in step S212 that the change start command has not been received (step S212: NO), the effect control process ends, and the process returns to step S201. .

  On the other hand, if it is determined in step S211 that an effect accompanied by a special symbol variation display is being executed (step S211: YES), the CPU 131 displays the display on the liquid crystal screen 50 as shown in FIG. Information related to the effect is acquired from the image sound control unit 140, and it is determined whether or not a character has appeared on the liquid crystal screen 50 by the display effect executed in accordance with the process of step S217 (step S221). If it is determined that no character has appeared (step S221: NO), the image sound control unit 140 continues the one-screen display on the liquid crystal screen 50 (step S222). That is, the process of drawing the main image on the VRAM_FB 1426 and outputting the main image to the liquid crystal display 5 is continuously executed by the VDP 142.

  When the CPU 131 determines that a character has appeared on the liquid crystal screen 50 (step S221: YES), the CPU 131 sets the setting information included in the change start command determined to have been received in the process of step S212, or the suspended information that is currently consumed. With reference to the pre-determined information corresponding to the sphere, the winning probability of the special symbol lottery is relative based on whether or not the special symbol that is stopped and displayed after the special symbol's variation display is a predetermined probability variable symbol In step S223, it is determined whether or not the probability variation jackpot for shifting from a low probability state having a low probability to a high probability state having a relatively high winning probability.

  If it is determined that the probable big hit is reached (step S223: YES), the CPU 131 moves the EL display 6 toward a position where the character on the liquid crystal screen 50 can be seen through the EL screen 60 (step S224). Specifically, a command instructing execution of processing for moving the EL display 6 toward a position where the character on the liquid crystal screen 50 can be visually recognized through the EL screen 60 is transmitted to the lamp control unit 150. On the other hand, the CPU 151 of the lamp control unit 150 controls the first stepping motor 29 and the second stepping motor 30 based on the command received from the effect control unit 130, and displays the character on the liquid crystal screen 50 as the EL screen 60. Then, the EL display 6 is moved to a position where it can be visually recognized (see FIGS. 25A to 25C). By performing the process of step S224, the EL display 6 automatically moves regardless of the operation of the effect key 38.

  When the process of step S224 is performed, the CPU 131 updates the position information of the EL screen 60 stored in the RAM 133 (step S225). Specifically, the latest position of the EL display 6 is detected based on the detection results (changes in electrical signals output from the respective optical sensors 56) by the respective optical sensors 56 provided on the liquid crystal screen 50. Based on the detection result, the position information of the EL screen 60 is rewritten. Then, the CPU 131 functioning as a position determination unit displays at least a part of the characters on the liquid crystal screen 50 at which the position of the EL screen 60 is located on the back side of the EL display 6 (the back side of the drawing in FIG. 1). It is determined whether or not the position is visible through (step S226). Specifically, the barycentric coordinates of the character on the liquid crystal screen 50 are acquired from the image sound control unit 140. Then, an area of the EL screen 60 arranged at a position corresponding to the position information of the EL screen 60 stored in the RAM 133 is set, and it is determined whether or not the acquired barycentric coordinates are included in this area.

  If the CPU 131 determines that at least a part of the character on the liquid crystal screen 50 is not visible through the EL screen 60 (step S226: NO), the process returns to step S224.

  When it is determined that at least a part of the character on the liquid crystal screen 50 is visible through the EL screen 60 (step S226: YES), the CPU 131 performs image acoustic control on the execution of the two-screen display by the liquid crystal screen 50 and the EL screen 60. The unit 140 is instructed (step S227). Specifically, a command for instructing execution of a two-screen display for displaying a decoration image that enhances the effect of the character on the EL screen 60 in accordance with the display effect on the liquid crystal screen 50 on which the character appears is an image sound control unit. 140. As a result, the character is displayed in a special display mode that cannot be expressed only by the liquid crystal screen 50 (see FIGS. 4A and 25C). Note that the command transmitted from the effect control unit 130 to the image sound control unit 140 includes the position information of the EL screen 60, and the CPU 141 of the image sound control unit 140 performs the position information and the setting process of FIG. A control signal including the generated setting information is output to the VDP 142. As a result, the main image is displayed on the liquid crystal screen 50, and the decoration image corresponding to the position of the EL screen 60 is displayed on the EL screen 60 as a sub image. The drawing process of the VDP 142 that enables two-screen display using the liquid crystal screen 50 and the EL screen 60 will be described in detail later.

  On the other hand, when it is determined that the probability variation jackpot is not obtained after the special symbol variation display is performed (step S223: NO), the CPU 131 determines whether or not the reach is greater than or equal to reach (step S230). That is, it is determined whether or not a special symbol lottery display starts to reach, or whether or not the special symbol lottery win probability is a normal jackpot that does not change the probability. When it is determined that it is not reach or more (step S230: NO), that is, when the display of the special symbol is not changed to reach and the display is lost after the change display ends, the CPU 131 performs the process of step S222 above to display the liquid crystal. The image sound control unit 140 continues the one-screen display on the screen 50.

  If the CPU 131 determines that it will develop to reach during the special symbol variation display or that it will normally be a big hit after the reach (step S230: YES), it instructs the lamp controller 150 to emit the button lamp 40 (see FIG. 11). A predetermined command is transmitted to cause the button lamp 40 built in the effect key 38 to emit light (step S231) (see FIG. 26A). Through the processing in step S231, the player is notified that the EL display 6 can be moved by operating the effect key 38. When the player operates the effect key 38, the CPU 131 accepts input of operation information from the effect key 38.

  Following the process of step S231, the CPU 131 determines whether or not the effect key 38 has been operated based on whether or not operation information has been input from the effect key 38 (step S232). When the CPU 131 determines that the effect key 38 is not operated (step S232: NO), the CPU 131 performs the process of step S222 and causes the image sound control unit 140 to continue the one-screen display on the liquid crystal screen 50. Conversely, if it is determined that the effect key 38 has been operated (step S232: YES), the EL display 6 is moved based on the operation information input from the effect key 38 (step S233). Specifically, a command instructing driving of the first stepping motor 29 and the second stepping motor 30 is transmitted to the lamp control unit 150. This command includes operation information input from the production key 38, and the CPU 151 functioning as a driving unit controls driving of the first stepping motor 29 and the second stepping motor 30 based on the operation information. . Thereby, the drive mechanism 10 (see FIG. 7) is driven, and the EL display 6 is moved to a position corresponding to the operation of the effect key 38 (see FIGS. 26B to 26D). As described above, when the CPU 131 receives the operation information input from the effect key 38 by the CPU 131, the CPU 151 moves the EL display 6 based on the operation information.

  After moving the EL display 6, the CPU 131 updates the position information on the EL screen 60 in the same manner as the process of step S 225 (step S 234), and the position of the EL screen 60 is at least one of the characters on the liquid crystal screen 50. It is determined in the same manner as the process of step S226 whether or not the position is visible through the EL screen 60 (step S235). When it is determined that at least a part of the character on the liquid crystal screen 50 is not visible through the EL screen 60 (step S235: NO), the CPU 131 performs the process of step S222 to display one screen display on the liquid crystal screen 50 as an image. The acoustic control unit 140 is continued.

  When it is determined that at least a part of the character on the liquid crystal screen 50 is visible through the EL screen 60 (step S235: YES), the CPU 131 performs image acoustic control on the execution of the two-screen display by the liquid crystal screen 50 and the EL screen 60. The unit 140 is instructed (step S236). Specifically, in accordance with the display effect on the liquid crystal screen 50 on which the character appears, a preview image of the display content for predicting the state of the character as a result of the progress of the display effect is displayed on the EL screen 60 as a sub image. A command instructing execution of the two-screen display is transmitted to the image sound control unit 140. Here, when a special jackpot is normally reached after the end of the special symbol variation display, a command instructing display of a preview image for predicting the victory of the character as illustrated in FIG. 4B is transmitted to the image sound control unit 140. In the case of a loss of what develops during the special symbol variation display, a command for instructing the display of a preview image for announcing the defeat of the character as illustrated in FIG. 140. The command transmitted from the effect control unit 130 to the image sound control unit 140 includes the position information of the EL screen 60, and the CPU 141 of the image sound control unit 140 is generated by the position information and the setting process of FIG. A control signal including the set information is output to the VDP 142. As a result, the main image is displayed on the liquid crystal screen 50 and a preview image corresponding to the position of the EL screen 60 is displayed on the EL screen 60 as a sub image. The drawing process of the VDP 142 that enables two-screen display using the liquid crystal screen 50 and the EL screen 60 will be described in detail later.

  Whether the CPU 131 has performed the process of step S222, the process of step S227, or the process of step S236, has received the change stop command set in the process of step S153 of FIG. Is determined (step S238). When the CPU 131 determines that the change stop command has been received (step S238: YES), an effect end command for instructing the end of the effect is transmitted to the image sound control unit 140 and the lamp control unit 150, and a series of game effects are performed. Terminate (step S239). As a result, the special symbol indicating the result of the special symbol lottery is stopped and displayed on the liquid crystal screen 50, and the result of the special symbol lottery (probability big hit, normal big hit or lost) is notified to the player.

  When the process of step S239 is performed or when it is determined that the change stop command has not been received (step S238: NO), the process returns to step S201 and the processes after step S201 are repeated.

[Command Execution Processing by Image Sound Control Unit 140]
Next, command execution processing performed by the image sound control unit 140 will be described with reference to FIGS. 27 and 28. FIG. Here, FIG. 27 is a flowchart illustrating an example of a command execution process performed by the image sound control unit 140. FIG. 28 is an explanatory diagram for explaining a drawing process performed by the VDP 142 when one screen display is performed on the liquid crystal screen 50. Note that the processing performed by the image sound control unit 140 described based on the flowcharts of FIG. 27 and the subsequent steps is performed according to a command issued by the CPU 141 based on a program stored in the control ROM 144 (see FIG. 12).

  The CPU 141 of the image sound control unit 140 determines whether or not the normal hold command transmitted from the effect control unit 130 in the process of step S205 (see FIG. 23) has been received (step S301). When it is determined that the normal hold command has been received (step S301: YES), the CPU 141 controls the drawing process by the VDP 142 to additionally display a normal mode (for example, yellow) hold display image on the liquid crystal screen 50 (step S302). ).

  When the process of step S302 is performed or when it is determined “NO” in step S301, has the CPU 141 received the special hold command transmitted from the effect control unit 130 in the process of step S208 (see FIG. 23)? It is determined whether or not (step S303). If it is determined that a special hold command has been received (step S303: YES), the CPU 141 controls the drawing process by the VDP 142 to additionally display a special mode (for example, red) hold display image on the liquid crystal screen 50 (step S304). ). Thereby, the prefetching effect by the hold display image is performed.

  When the process of step S304 is performed, or when it is determined “NO” in step S303, has the CPU 141 received the pending digest command transmitted from the effect control unit 130 in the process of step S214 (see FIG. 23)? It is determined whether or not (step S305). When it is determined that the hold digest command has been received (step S305: YES), the drawing process by the VDP 142 is controlled to delete the oldest hold display image from the liquid crystal screen 50 (step S306). Specifically, when the information indicating that the reserved ball related to the first special symbol lottery is digested is included in the reserved digest command, the reserved display image related to the first special symbol lottery displayed on the liquid crystal screen 50 is displayed. Of these, the VDP 142 is caused to execute a process of erasing the initially displayed on-hold display image and shifting the remaining on-hold display image to the left side. On the other hand, when the information indicating that the reserved ball related to the second special symbol lottery is digested is included in the reserved digest command, first of the held display images related to the second special symbol lottery displayed on the liquid crystal screen 50. The VDP 142 is caused to execute a process of erasing the displayed held display image and shifting the remaining held display image to the left side.

  If the process of step S306 is performed or if “NO” is determined in step S305, has the CPU 141 received the effect start command transmitted from the effect control unit 130 in the process of step S217 (see FIG. 23)? It is determined whether or not (step S307). If it is determined that the effect start command has been received (step S307: YES), the CPU 141 performs control for realizing the game effect determined by the CPU 131 of the effect control unit 130 based on the information included in the effect start command. A signal is output to the VDP 142 and the sound DSP 143 to start a game effect by the liquid crystal display 5 or the speaker 35 (step S308).

  If the process of step S308 is performed, or if “NO” is determined in step S307, has the CPU 141 received the effect end command transmitted from the effect control unit 130 in the process of step S239 (see FIG. 24)? It is determined whether or not (step S309). When it is determined that the effect end command has been received (step S309: YES), the effect by the liquid crystal display 5 or the speaker 35 is ended (step S310).

  When it is determined that the effect end command has not been received (step S309: NO), the CPU 141 determines whether the instruction in step S222, step S227, or step S236 in FIG. 24 is input. It is determined whether or not to perform two-screen display using both the screen 50 and the EL screen 60 (step S311).

  When the instruction to continue the one-screen display is instructed by the process of step S222 (step S311: NO), the CPU 141 draws only the main image and instructs the VDP 142 to display one screen to be output to the liquid crystal display 5. A control signal not including the setting information generated by the setting process of FIG. 14 is output to the VDP 142 (step S312). On the other hand, as illustrated in FIG. 28, the drawing engine 1424 of the VDP 142 includes a first image indicating a decorative pattern and a character, a second image as a background image indicating a background such as a decorative pattern, and a character image. As a third image is read from the image ROM 148 to the VRAM_RS 1425, a main image that is an image obtained by synthesizing these images is drawn in the first frame buffer 1426A (or the second frame buffer 1426B), and the output circuit 1427 The main image is read from the first frame buffer 1426A (or the second frame buffer 1426B) and output to the liquid crystal display 5.

  On the other hand, when the two-screen display is instructed by the process of step S227 or step S236 (step S311: YES), the CPU 141 draws the main image and the sub image and outputs them to the liquid crystal display 5 and the EL display 6. In order to instruct the VDP 142 to display the screen, a control signal including the setting information generated by the setting process of FIG. 14 and the position information of the EL screen 60 acquired from the effect control unit 130 is output to the VDP 142 (step S313). As a result, an effect image including a display object such as a character is displayed on the liquid crystal screen 50, and an image of display content related to the display object (the above-described decoration image or preview image) is displayed on the EL screen 60.

[Drawing process for two-screen display]
The drawing process performed by the VDP 142 for one-screen display is as described above with reference to FIG. Hereinafter, the drawing process performed by the VDP 142 for the two-screen display will be described in detail with reference to FIGS. 29 to 32. Here, FIG. 29 is a flowchart illustrating an example of a drawing process performed by the VDP 142 for two-screen display. FIG. 30 is an explanatory diagram for describing a drawing process performed by the VDP 142 when the division number SN is set to “0”. FIG. 31 is an explanatory diagram for describing a drawing process performed by the VDP 142 when the division number SN is set to “4”. FIG. 32 is an explanatory diagram for describing divided image output processing by the output circuit 1427. Note that the drawing process performed by the VDP 142 described based on the flowcharts of FIG. 29 and subsequent figures is performed based on a control signal generated by the CPU 141 based on a program stored in the control ROM 144. Further, in the following description, a case where drawing processing is performed using the first frame buffer 1426A out of the first frame buffer 1426A and the second frame buffer 1426B will be described as an example, but the second frame buffer 1426B is used. The drawn process is also performed in the same manner as the drawn process using the first frame buffer 1426A.

  When a control signal including setting information and position information on the EL screen 60 is input from the CPU 141 to the VDP 142, the drawing engine 1424 displays a frame buffer used for drawing processing of the main image and the sub image, as shown in FIG. Select (step S401). Specifically, of the first frame buffer 1426A and the second frame buffer 1426B, the frame buffer that outputs the image to the liquid crystal display 5 and the EL display 6 is specified, and the one that does not output the image. The frame buffer is selected as the frame buffer to be used for the current frame drawing process.

  For example, when the first frame buffer 1426A is selected in step S401, the drawing engine 1424 draws the main image displayed on the liquid crystal display 5 in the first frame buffer 1426A (step S402). For example, a first image indicating a decorative design and a character, a second image as a background image indicating a background such as a decorative design, and a third image as a character image are read from the image ROM 148 to the VRAM_RS 1425 and these images are read out. The main image, which is an image obtained by combining the images, is drawn in the first frame buffer 1426A (see FIG. 30).

  Subsequently, the drawing engine 1424 extracts the position information of the EL screen 60 included in the control signal transmitted from the CPU 141, and among the main images drawn in the first frame buffer 1426A in the process of step S402, An area corresponding to the position indicated by the position information is copied to generate a copy image (step S403). Specifically, 240 × 320 (vertical pixel number × horizontal pixel number) pixel data corresponding to the position information is copied from the main image drawn in the first frame buffer 1426A, and is copied to the VRAM_RS 1425 as a copy image. Store.

  Then, as shown in FIG. 30, the drawing engine 1424 synthesizes a difference image (decorative image or preview image) indicating display contents that are not displayed on the liquid crystal screen 50 but displayed only on the EL screen 60 with the copy image. Thus, a sub image is generated (step S404). Specifically, the difference image corresponding to the position information on the EL screen 60 is read from the image ROM 148 to the VRAM_RS 1425, and the read difference image is synthesized on the VRAM_RS 1425 with a copy image using, for example, the Z buffer method. Generate an image. In FIG. 30, the position of the sub image with respect to the main image is indicated by a broken line 18. As a result of the processing in step S404, in the present embodiment, a sub-image (see FIG. 16C) in which the vertical pixel number L3 is “240” and the horizontal pixel number C3 is “320” is generated.

  In step S <b> 404, the drawing engine 1424 determines a difference image to be read from the image ROM 148 based on information included in the control signal transmitted from the CPU 141. For example, when the control signal includes information indicating the display effect that the character wins as a result of the progress of the display effect, the difference image (for example, illustrated in FIG. 4B) showing the display content for announcing the victory of the character. Read-out sword and a preview image indicating the characters “chance !?” are read from the image ROM 148 to the VRAM_RS 1425. Conversely, when the control signal includes information indicating the display effect that the character loses as a result of the progress of the display effect, the difference image (for example, illustrated in FIG. 4C) showing the display content for notifying the character's defeat. The image of the character on the knee and a preview image showing the characters “Pinch !?” are read from the image ROM 148 to the VRAM_RS 1425. Further, when the control signal includes information indicating a display effect that enhances the character effect, a difference image (for example, a decorative image illustrated in FIG. 4A) for enhancing the character effect is displayed. Read from the ROM 148 to the VRAM_RS 1425. By generating a sub-image based on the material data read in this way, a preview image for notifying the state of the character as a result of the progress of the display effect determined by the CPU 101 of the game control unit 100, A character decoration image for notifying the probable jackpot is displayed on the EL screen 60.

  In the present embodiment, since a sub image is generated based on a copy image obtained by copying a partial area of the main image, the character displayed on the liquid crystal screen 50 is also displayed on the EL screen 60. .

  As described above, the drawing engine 1424 combines the difference image with the copy image obtained by copying the area corresponding to the position of the EL screen 60 from the main image, and displays it on the EL screen 60. Sub-images are generated.

  When the sub-image is generated, the drawing engine 1424 determines whether the control signal output from the CPU 141 includes information indicating the reduction ratio set by the process of step S10 (see FIG. 14) as setting information. Then, it is determined whether or not a reduction ratio is set (step S405). If it is determined that the reduction ratio is set (step S405: YES), the drawing engine 1424 applies the sub-image generated in the process of step S404 based on the information indicating the reduction ratio extracted from the control signal. Reduction processing is performed (step S406). For example, when the reduction ratio is set to “0.5”, the rendering engine 1424 determines that the vertical pixel number L3 is “240” from the sub-image having the vertical pixel number L3 of “480” and the horizontal pixel number C3 of “640”. (= 480 × 0.5) and the horizontal pixel number C3 is “320” (= 640 × 0.5). As a result, even if it is divided, it is possible to draw a sub-image that could not be drawn in the empty area.

  When the drawing engine 1424 performs the process of step S406 or determines that the reduction ratio is not set (step S405: NO), the division number SN included in the control signal output from the CPU 141 is “ Whether it is “0” or not is determined (step S407). If it is determined that the number of divisions SN is “0” (step S407: YES), the sub image in the VRAM_RS 1425 can be drawn in the empty area of the first frame buffer 1426A without being divided. Drawing is performed in an empty area (step S408). As described above, when the CPU 141 determines in advance that the division is unnecessary, the drawing engine 1424 does not divide the sub image, and the free area in the first frame buffer 1426A formed by drawing the main image. To draw.

  FIG. 30 shows an example in which the sub image is drawn in the empty area of the first frame buffer 1426A without being divided. As illustrated in FIG. 30, unlike the example described above for the main image having the vertical pixel number L2 of “600” and the horizontal pixel number C2 of “800”, the vertical pixel number L1 is “840” and the horizontal pixel. When a frame buffer having the number C1 of “1120” is prepared, the minimum vertical pixel number L4 of the empty area of the frame buffer is “240” (= 840−600), and the minimum horizontal pixel number C4 is “320”. (= 1120-800). When drawing a sub-image in which the vertical pixel number L3 is “240” and the horizontal pixel number C3 is “320” in such an empty area, the vertical pixel number L3 of the sub-image is equal to the minimum vertical pixel number L4, and Since the horizontal pixel number C3 is equal to the minimum horizontal pixel number L4, sub-image division is not necessary. In such a case, the division number SN is set to “0”, and the drawing engine 1424 draws the sub image in the empty area of the first frame buffer 1426A without dividing the sub image.

  When the process of step S408 is performed, the drawing engine 1424 completes the process of displaying the image of the previous frame stored in the second frame buffer 1426B, and the first frame buffer 1426A is processed by the processes of steps S402 and S408. It is determined whether or not it is time to display the image of the next frame drawn in step S409. If it is determined that the display timing has not come (step S409: NO), the process returns to step S409 to enter a standby state.

  If it is determined by the drawing engine 1424 that the display timing has come (step S409: YES), the output circuit 1427 reads the main image from the first frame buffer 1426A as shown in FIG. 30, and the liquid crystal display 5 Are output from the first frame buffer 1426A and output to the EL display 6 (step S411).

  On the other hand, the drawing engine 1424 determines that the division number SN included in the control signal output from the CPU 141 as the setting information is not “0” (an even number of 2 or more) (step S407: NO). The sub-image generated in the VRAM_RS 1425 in the process of step S404 or the sub-image reduced in the process of step S406 is drawn as a divided image in the empty area of the first frame buffer 1426A (step S413).

  In FIG. 31, the divided image SN is “4”, the vertical pixel number L3 is “240”, and the horizontal pixel number C3 is “320”, which is four divided images (see FIG. 16C). When the divided image size SS is set to 120 × 160 (the number of vertical pixels × the number of horizontal pixels) (see the diagram on the right side of FIG. 16C), the main image is stored in the first frame buffer 1426A. A state is shown in which a sub image is drawn as four divided images with respect to an empty area generated in the case of drawing. If the CPU 141 determines in advance that division of the sub image is necessary, the drawing engine 1424 divides the sub image into a plurality of regions as illustrated in FIG. Are drawn in the empty area of the first frame buffer 1426A.

  As described above, when the CPU 141 determines that the division is necessary and the divided image size SS and the number of divisions SN are set in advance, the drawing engine 1424 sets the first frame as a divided image based on the settings. Drawing is performed in an empty area of the buffer 1426A.

  When the divided image is drawn, the drawing engine 1424 determines whether or not it is time to display the image of the next frame drawn in the first frame buffer 1426A in the processes in steps S402 and S413, similarly to the process in step S409. Determination is made (step S414). If it is determined that the display timing has not come (step S414: NO), the process returns to step S414 to enter a standby state. On the other hand, if it is determined by the drawing engine 1424 that the display timing has come (step S414: YES), the output circuit 1427 reads the main image from the first frame buffer 1426A as shown in FIG. 31, and the liquid crystal display 5 (Step S415).

  Subsequently, the drawing engine 1424 determines whether or not the reduction magnification is set based on whether or not information indicating the reduction magnification is included in the control signal from the CPU 141 (step S416). When the drawing engine 1424 determines that the reduction ratio is not set (step S416: NO), that is, when the processing of steps S9 and S10 is not performed in the setting processing illustrated in FIG. Then, the divided image is read from the first frame buffer 1426A and output to the EL display device 6 as a sub image (step S417).

  By the way, the main image is stored in the first frame buffer 1426A in the same arrangement as the pixels (color liquid crystal element 52) constituting the liquid crystal screen 50. For this reason, the pixel data constituting the main image may be output to the liquid crystal display 5 in the same order. When the sub image is drawn in the first frame buffer 1426A without being reduced or divided (see FIG. 30), the sub image is stored in the first frame buffer 1426A with the same arrangement as the pixels constituting the EL screen 60. Stored. For this reason, the pixel data constituting this sub-image may be output to the EL display 6 in the same order.

  On the other hand, when the sub-image is drawn as the divided image in the first frame buffer 1426A (see FIG. 31), the sub-image is stored in the first frame buffer 1426A in an arrangement different from the pixels constituting the EL screen 60. Stored. Therefore, the output circuit 1427 configures the divided images so that each pixel data that configures the sub image is output in a predetermined order that should be output so that the sub image is correctly displayed on the EL screen 60. Read each pixel data. For example, when four divided images are stored in the first frame buffer 1426A in the arrangement illustrated in FIG. 31, the output circuit 1427 displays the same display as the upper left region of the sub image, as shown in FIG. For the first divided image showing the content, processing for reading out and outputting pixel data for one line in the horizontal direction 12, and for the second divided image showing the same display content as the upper right region of the sub-image, The process of reading out and outputting pixel data for one line in the horizontal direction 12 is repeated alternately. Thereby, pixel data corresponding to the upper half of the sub-image is output. Subsequently, for the third divided image showing the same display content as the lower left region of the sub image, a process of reading out and outputting pixel data for one line in the horizontal direction 12, and a lower right region of the sub image The process of reading out and outputting pixel data for one line in the horizontal direction 12 is alternately repeated for the fourth divided image showing the same display content. As a result, pixel data corresponding to the lower half of the divided image is output.

  As described above, the output circuit 1427 reads the divided image so that the sub image is correctly displayed on the EL screen 60 even when the sub image is rendered as the divided image.

  On the other hand, if it is determined by the drawing engine 1424 that the reduction ratio is set (step S416: YES), the drawing engine 1424 enlarges the divided image and then outputs it to the EL display 6 as a sub-image (step). S418). Specifically, an enlargement process is performed on each divided image in the first frame buffer 1426A using the reciprocal of the reduction ratio as an enlargement ratio, and the divided image subjected to the enlargement process is output to the output circuit 1427. As a result, a sub-image having the same number of pixels as the screen resolution of the EL screen 60 is output. For example, when the reduction magnification is set to “0.5”, the drawing engine 1424 sets the enlargement magnification to 2 times (= 1 / 0.5). Then, each divided image stored in the first frame buffer 1426A is doubled on the VRAM_RS, and each divided image subjected to the enlargement process is output to the output circuit 1427 as a sub image.

  After the process of step S411, the process of step S417, or the process of step S418 is performed, the process returns to step S401, and the process after step S401 is performed on the next frame.

  According to the rendering processing of this embodiment, a sub image is generated by synthesizing a difference image with a copy image obtained by copying a partial area of the main image. The positional deviation of the object indicated by can be prevented. For example, in the case where the effect that the character has a sword is expressed by the two-screen display (when the display effect illustrated in FIG. 4B is performed), a difference image that can be displayed only on the EL screen 60 is displayed on the EL screen 60. In addition to the sword image shown, the character is also displayed. For this reason, when the EL display 6 is displaced from a desired position, it is possible to prevent an unnatural display such that the sword looks away from the character's hand.

[Operational effects of this embodiment]
As described above, according to the present embodiment, the EL display 6 is configured to be movable, and the display object (for example, a character) displayed on the liquid crystal screen 50 can be visually recognized through the EL screen 60. When moving to the position, a sub-image indicating the display content related to the display object is displayed on the EL screen 60. As described above, the two-screen display in which the images displayed on the different image display devices are displayed in a superimposed manner can provide a highly interesting and effective display effect, and it is effective that the game by the player becomes monotonous. Can be prevented.

  In addition, according to the present embodiment, the sub-image indicating the display content corresponding to the display effect performed on the liquid crystal screen 50 is displayed on the EL screen 60, so that an appropriate sub-image corresponding to the display object is displayed on the EL screen 60. As a result, a more effective display effect can be performed.

  Further, according to the present embodiment, the sub-image is rendered in a state of being divided so as to fit in the free area of the first frame buffer 1426A or the second frame buffer 1426B. For this reason, the main image displayed on the liquid crystal screen 50 and the sub-image displayed on the EL screen 60 are displayed as one drawing means (in this embodiment, the drawing engine 1424) without providing a frame buffer having a larger capacity than necessary. ) Can be drawn in one frame buffer (first frame buffer 1426A or second frame buffer 1426B). Therefore, an increase in manufacturing cost due to the provision of the liquid crystal display 5 and the EL display 6 can be minimized.

  Further, when manufacturing a gaming machine to which an image display (for example, EL display 6) different from the liquid crystal display 5 for displaying special symbols or the like is manufactured, the screen resolution of the EL display 6 (= vertical pixels of the sub-image) (Number × number of horizontal pixels) varies greatly depending on what screen resolution EL display 6 is added. According to the present embodiment, the divided image size SS and the number of divisions SN are calculated so that the sub image fits in the free area of the first frame buffer 1426A or the second frame buffer 1426B, and the sub image is determined based on the calculation result. Rendered as a split image. For this reason, even if the screen resolution of the liquid crystal screen 50 or the EL screen 60 changes, the drawing process to the first frame buffer 1426A or the second frame buffer 1426B can be appropriately performed.

  Further, according to the present embodiment, the sub image is divided into images only when the sub image cannot be drawn unless the sub image is divided into the empty area of the first frame buffer 1426A (or the second frame buffer 1426B) after the main image is drawn. When the sub image is drawn as it is and is not required to be divided, the sub image is directly drawn in the empty area (see FIG. 30). For this reason, it is possible to perform an appropriate drawing process according to the size of the sub-image with respect to the empty area of the first frame buffer 1426A or the second frame buffer 1426B.

[Modification of drawing process]
Hereinafter, a modification of the drawing process will be described with reference to FIGS. 33 and 34. Here, FIG. 33 is a flowchart showing a modification of the drawing process performed by the VDP 142 for two-screen display. FIG. 34 is an explanatory diagram for describing a modified example of the drawing process executed by the VDP 142. In addition, about the process which is common in each process of the drawing process (refer FIG. 29) performed with the pachinko game machine 1 which concerns on the said embodiment, the same step number is attached | subjected and the description is abbreviate | omitted.

  When the main image is drawn in the first frame buffer 1426A in the process of step S402, the drawing engine 1424 displays the EL screen 60 as a sub image based on the position information of the EL screen 60 included in the control signal from the CPU 141. The contents of the sub-image to be displayed are determined (step S421). Specifically, the image ROM 148 stores sub-image content information indicating the content of the sub-image associated with the position of the EL screen 60 and the content of the display effect, and the drawing engine 1424 displays the EL screen. The content of the sub image is determined by reading out the sub image content information corresponding to the 60 position information and the information indicating the content of the display effect from the image ROM 148.

  Subsequently, the drawing engine 1424 reads material data necessary for generating the sub image indicated by the sub image content information from the image ROM 148 and stores it in the VRAM_RS 1425, and uses the material data to determine the processing in step S421. A sub-image having the above contents is generated (step S422). Based on this sub-image, the processing from step S405 described above is performed. In FIG. 34, after the sub image generated by the process of step S422 is rendered as four divided images in the empty area of the first frame buffer 1426A, each divided image is output as the original sub image. It is shown.

  According to this drawing process, it is not necessary to synthesize a copy image and a difference image when drawing a sub-image, so that the processing load on the VDP 142 can be reduced. In this drawing process, when a sub-image (for example, an image showing only character information) is displayed on the EL screen 60, the positional deviation between the display object on the liquid crystal screen 50 and the image displayed only on the EL screen 60 is not a big problem. Is particularly effective. Therefore, when displaying on the EL screen 60 an image in which the positional deviation between the display object on the liquid crystal screen 50 and the object displayed only on the EL screen 60 is displayed, the processing of steps S403 and S404 in FIG. 29 is performed. In the case where a sub-image is generated and an image on which the positional deviation between the display object on the liquid crystal screen 50 and the object displayed only on the EL screen 60 is not a big problem is displayed on the EL screen 60, steps S421 and S422 in FIG. The process of generating the sub image may be switched according to the display content of the sub image, such as generating the sub image by performing the above process.

  Although the case where the drawing engine 1424 determines the content of the sub image by the processing in step S421 has been described here, the CPU 141 may determine the content of the sub image. In this case, transmission of position information from the CPU 141 to the drawing engine 1424 becomes unnecessary.

[Modification of Drive Mechanism 10]
FIG. 35 is a diagram for describing a modified example of the drive mechanism 10. In the above embodiment, the case where the EL display 6 is moved by the drive mechanism 10 including the lift drive mechanism 200 and the slide drive mechanism 220 has been described. However, the EL display 6 is moved by another drive mechanism. May be. For example, as illustrated in FIG. 35A, an arm 602 that is rotatably connected to a base 601 via a shaft 605 and a arm 602 that is rotatable via a shaft 606. A drive mechanism including a connected arm 603 and an arm 604 rotatably connected to the arm 603 via a shaft 607 and to which the EL display 6 is fixed may be used.

  Further, as exemplified in FIG. 35B, a driving mechanism in which the transparent EL display 700 moves by rotating the transparent EL display 700 fixed to the tip of the arm 701 about the shaft 702 may be used. Good. In this case, since the structure of the drive mechanism is simpler than that of the drive mechanism 10, the manufacturing cost of the pachinko gaming machine 1 can be further reduced.

[Other variations]
In the above embodiment, the case where the display object in the present invention is a character that performs a notice effect has been described. However, if the display object in the present invention is a display object displayed on the liquid crystal screen 50, for example, an item, a decorative design, It may be a background image, a hold display image, a character image, or the like.

  Moreover, although the said embodiment demonstrated the case where the sub image which shows the display content according to the display effect determined by the game control part 100 was displayed on the EL screen 60, the display effect determined by the game control part 100 was demonstrated. A sub image showing display contents unrelated to the display may be displayed on the EL screen 60. That is, instead of a preview image for notifying the state of the character after the display effect has progressed, an image having display contents irrelevant to the character may be displayed on the EL screen 60 as a sub image.

  Moreover, although the said embodiment demonstrated the case where the image sound control part 140 performs 2 screen display according to the fluctuation | variation start command which instruct | indicates execution of the display effect determined by the effect control part 130, prior determination information is included. The image sound control unit 140 may perform two-screen display in response to the hold command. As a result, the EL display 6 moves at the timing when the game ball wins the first start port 21 or the second start port 22, and a decorative image that enhances the effect of the character on the liquid crystal screen 50 is displayed on the EL screen 60, for example. It is possible to perform an effective look-ahead effect that has never been seen before. That is, it is possible to increase variations in prefetching effects.

  Moreover, although the said embodiment demonstrated the case where CPU141 functions as a calculation means which calculates division image size SS and the division | segmentation number SN, the pachinko game machine 1 does not necessarily need to be provided with a calculation means. For example, the divided image size SS and the division number SN may be stored in advance in the control ROM 144, for example, instead of being calculated by the setting process.

  Moreover, although the said embodiment demonstrated the case where the pachinko machine 1 was provided with the division | segmentation determination means (CPU141 in the said embodiment) which determines whether the division | segmentation of a sub image is required, for example, a division | segmentation is required. If it is clear, the sub-image may be drawn as a divided image without performing the process for determining whether or not the division is necessary. That is, the gaming machine of the present invention does not necessarily have to include a division determination unit.

  In the above-described embodiment, the case where one drawing engine 1424 performs drawing processing of both the main image and the sub image has been described. However, the sub image is drawn by a drawing engine different from the drawing engine that performs drawing processing of the main image. The drawing process may be performed.

  Moreover, although the said embodiment demonstrated the case where the position of EL screen 60 was detected based on the detection result of the optical sensor 56, it replaced with this and the number of steps of the 1st stepping motor 29 and the 2nd stepping motor 30 was replaced. The position of the EL screen 60 may be detected based on the above. Further, visible light and ultraviolet light are emitted from the backlight of the liquid crystal display 5 toward the EL display 6, and only the ultraviolet light among the reflected light from the frame 61 of the EL display 6 is directed to the optical sensor 56 side. A configuration including a UV filter to be transmitted may be employed to detect the position of the EL display 6 based on the result of receiving ultraviolet light by the optical sensor 56. In this case, since sensing is performed using invisible light, the influence of disturbance due to visible light such as hall illumination can be reduced, and the position detection accuracy of the EL display 6 can be improved.
