  When the substrate container 220a and the substrate container 220b are closed as shown in FIG. 6B, on the opposite side of the hinge shaft portion 250 and the hinge receiving portion 225, that is, on the right side in FIG. 7A, the substrate container 220b. The fitting claws 227 of the substrate container 220a are fitted to the convex portions 253, and the substrate container 220a and the substrate container 220b are held closed.

  Further, when the substrate container 220a and the substrate container 220b are closed, the caulking portion 228 of the substrate container 220a and the caulking portion 254 of the substrate container 220b are adjacent to each other. The caulking member 263 is inserted into the caulking portion 228 and the caulking portion 254 adjacent to each other to caulk the substrate container 220a and the substrate container 220b (see FIG. 7B).

  As shown in FIGS. 8A, 8B, and 8C, the caulking member 263 is formed by connecting insertion portions 263a and 263b with a connecting portion 263c. Each of the insertion portions 263a and 263b has a barbed portion 263d at the tip. The barb 263d has elasticity, and when no external force is applied, the umbrella is opened as shown in FIGS. 8A, 8B, and 8C, and the umbrella closes when pressed from the outside. It becomes a state.

  Three caulking portions 228 and three caulking portions 254 are provided vertically, and the caulking member 263 is inserted between adjacent ones. Which of the three caulking portions 228 and the caulking portion 254 is used is determined in advance so as to be used in order from the top.

  The caulking portion 228 has a hole 228a having a shape corresponding to the insertion portion 263a. In other words, the insertion portion 263a can be inserted into the hole 228a, and during the insertion operation, the inner wall of the hole 228a can be inserted by pressing the barbed portion 263d from outside to close the umbrella, and when the insertion is completed, external force is applied to the barbed portion 263d. When the umbrella is not opened, the barb 263d is hooked on the contact part 228b and the insertion part 263a cannot be pulled out.

  Similarly, the caulking portion 254 has a hole 254a having a shape corresponding to the insertion portion 263b. That is, the insertion portion 263b can be inserted into the hole 254a, and during the insertion operation, the inner wall of the hole 254a can be inserted by pressing the barbed portion 263d from outside to close the umbrella, and when the insertion is completed, external force is applied to the barbed portion 263d. When the umbrella is not opened, the barb 263d is hooked on the contact part 254b and the insertion part 263b cannot be pulled out.

  Since the insertion part 263a and the insertion part 263b are connected by the connection part 263c, the substrate container 220a and the substrate container are inserted in the state where the caulking member 263 is inserted into the adjacent caulking part 228 and the caulking part 254 and caulked. 220b cannot be opened, and the sub-control boards 221 and 222 accommodated in the sub-control board accommodation case 220 cannot be touched. At this time, the sub control board 221 and the sub control board 222 are overlapped and accommodated in the sub control board accommodation case 220.

  9A and 9B are diagrams for explaining caulking by the caulking member 263. FIG. 9A is a plan view showing a state in which the caulking member 263 is inserted into the caulking portion 228 and the caulking portion 254 adjacent to each other, and FIG. FIG. 10 is a perspective view showing a state in which a caulking member 263 is inserted into the second insertion portion from the top in the caulking portion 254.

  As described above, when the caulking member 263 is inserted into the adjacent caulking portion 228 and the caulking portion 254, the caulking portion 263d is hooked on the abutting portions 228b and 254b, and the insertion portions 263a and 263b cannot be pulled out. The body 220a and the substrate container 220b are caulked. Later, when it is necessary to open the sub-control board housing case 220 to replace the sub-control board 221 or 222 and the caulking is released, the connecting portion 263c is cut by a nipper or the like (see FIG. 9A). It is necessary to release the connection between the insertion portion 263a and the insertion portion 263b. Even after the connection portion 263c is cut, the insertion portion 263a remains in the hole 228a, and the insertion portion 263b remains in the hole 254a.

  FIG. 9B shows that the caulking member 263 is inserted into the uppermost one of the three caulking portions 228 and caulking portions 254, and then the connecting portion 263c of the caulking member 263 is cut, so that the substrate container The figure which shows the state which replaced | exchanged 220a for another thing and inserted the caulking member 263 into the caulking part 228 and the caulking part 254 which are the 2nd from the top, and the board | substrate accommodating body 220a and the original board | substrate accommodating body 220b. It is.

  In FIG. 9B, since the replaced substrate container 220a has not been caulked until now, no insertion portion 263a remains in any of the three caulking portions 228. On the other hand, since the original substrate container 220b is caulked using the upper caulking portion 254, the insertion portion 263b remains in the upper caulking portion 254. Depending on the remaining state of the insertion portions 263a and 263b, the opening history of the sub control board accommodation case 220 can be left.

  FIG. 10 is a perspective view for explaining how to replace the substrate container 220a holding and fixing the sub-control board 222.

The dummy container 220bx has a convex part 253x to which the fitting claw part 227 of the substrate container 220a is fitted, and has a handle 255x to be used for carrying. Further, as can be seen at a glance, the dummy container 220bx has a color different from that of the sub-control board housing case 220 and is transparent so that the inside can be seen. Further, the dummy container 220bx is not provided because a vent hole is not necessary. By combining the dummy container 220bx, the replacement substrate container 220a can be protected during carrying.

  The replacement worker takes the replacement storage case 220x shown in FIG. 10A to the place where the sub-control board storage case 220 to be replaced is located, and performs the replacement work.

  First, the connecting portion 263c of the caulking member 263 that caulks the sub-control board housing case 220 to be replaced is cut, and the board housing body 220a (old) before replacement is removed. At the same time, in the replacement housing case 220x, the substrate housing body 220a (new) holding and fixing the new sub-control board 222 is removed from the dummy housing body 220bx. At this time, the dummy container 220bx does not have a caulking portion, and the substrate container 220a (new) is removed simply by removing the fitting claw portion 227 of the substrate container 220a from the convex portion 253 of the dummy container 220bx. be able to.

  Subsequently, as described above, the substrate container 220a (new) is combined with the substrate container 220b, and the caulking portion 228 and the caulking portion 254 immediately below the caulking portion 254 that have been used up to now are used. 228 and caulking portion 254 are inserted and caulked. The removed substrate container 220a (old) before replacement is combined with the dummy container 220bx and brought back by the replacement worker. By combining the dummy container 220bx, the substrate container 220a (old) can be protected during carrying.

  The replacement storage case 220x that stores the sub-control board 222 (new) before the replacement and the replacement storage case 220x that stores the sub-control board 222 (old) after the replacement are not carried by the replacement worker. You may send it by etc.

  The replacement worker can perform the replacement work without directly touching the sub-control board 222 or the sub-control board 221, and there is no possibility that the sub-control board 222 or the sub-control board 221 is damaged.

  The LED 10 of the notification unit 259 notifies the operation status of the sound source IC (sound IC) 418 (notification on hardware). If the operation is normal, the LED 9 is blinked, and if abnormal, it is turned on or off.

  Referring to FIG. 12 (b), the notification unit 246 includes five LEDs.

  The LED 1 of the notification unit 246 notifies the supply status of 12V power to the second sub-control unit 500 by the power supply device 252 (notification on hardware). If the 12V power supply is normal, the LED 1 is turned on, and if it is abnormal, the LED 1 is turned off.

  The LED 2 of the notification unit 246 notifies the supply status of all 1.2 to 3.3 V power to the second sub control unit 500 by the power supply device 252 (notification on hardware). If all 1.2-3.3V power supply is normal, the LED 2 is turned on, and if any one is abnormal, the LED 2 is turned off.

  The LED 3 of the notification unit 246 notifies the operation status of the CPU 504 of the second sub control unit 500 (notification on software). The CPU 504 blinks so that the LED 3 is repeatedly turned on / off every 500 ms under normal conditions. Since this processing cannot be performed when the CPU 504 is abnormal, the CPU 504 remains on or off, and the CPU 504 is notified of the abnormality.

  The LED 5 of the notification unit 246 notifies the communication status with the first sub-control unit 400 (notification on software). If the operation is normal, the LED 5 is blinked, and if abnormal, it is turned on or off.

<Main control unit main processing>
A main control unit main process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit.

  As described above, the main control unit 300 is provided with the start signal output circuit (reset signal output circuit) 338 that outputs the start signal (reset signal) when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal has been input resets by a reset interrupt and executes the main process of the main control unit shown in FIG. 13 in accordance with a control program stored in advance in the ROM 306.

  When power is turned on, first, various initial settings are made in step SA01. In this initial setting, setting of a stack initial value to the stack pointer (SP) of the CPU 304, setting of interrupt prohibition, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, operation permission to the WDT 314, and initial setting Set the value.

  In step SA03, medal insertion / start operation acceptance processing is executed. Here, it is checked whether or not a medal has been inserted, and the winning line display lamp 120 is turned on in response to the insertion of the medal. Note that when a re-win is won in the previous game, a process of inserting the same number of medals as the number of medals inserted in the previous game is performed, so that it is not necessary for the player to insert medals. Further, it is checked whether or not the start lever 135 has been operated. If there is an operation of the start lever 135, the process proceeds to step SA05.

  In step SA05, the number of inserted medals is determined, and an effective winning line is determined.

  In step SA07, the random number generated by the random number generation circuit 316 is acquired. If a random number cannot be acquired by this random number acquisition process, a random number acquisition error command is transmitted to the first sub-control unit 400.

  In step SA09, the winning combination lottery table stored in the ROM 306 is read according to the current gaming state, and an internal lottery is performed using this and the random value acquired in step SA07. As a result of the internal lottery, when any winning combination (including an operating combination) is won internally, the flag of the winning combination is turned ON.

  In step SA11, reel stop data is selected based on the internal lottery result.

  In step SA13, rotation of all reels 110 to 112 is started.

  In step SA15, the stop buttons 137 to 139 can be received. When any one of the stop buttons is pressed, the reel stop control in which one of the reels 110 to 112 corresponding to the pressed stop button is selected in step SA11. Stop based on data. When all the reels 110 to 112 are stopped, the process proceeds to Step SA17.

  In step SA17, winning determination is performed. Here, when a picture combination corresponding to some winning combination is displayed on the activated winning line 114, it is determined that the winning combination is won. For example, if “bell-bell-bell” is aligned on the activated winning line, it is determined that the player has won the bell.

  In step SA19, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out according to the number of winning lines.

  In step SA21, game state control processing is performed. Thus, one game is completed. Thereafter, the game proceeds by returning to step SA03 and repeating the above-described processing.

<Processing of first sub-control unit 400>
Processing of the first sub control unit 400 will be described with reference to FIG. FIG. 5A is a flowchart of main processing executed by the CPU 404 of the first sub control unit 400. FIG. 5B is a flowchart of command reception interrupt processing of the first sub control unit 400. FIG. 5C is a flowchart of the timer interrupt process of the first sub control unit 400.

  First, in step SC01 in FIG. 9A, various initial settings are performed. When power is turned on, an initialization process is first executed in SC01. In this initialization processing, initialization of input / output ports, initialization processing of a storage area in the RAM 408, and the like are performed.

  In step SC03, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10, and when the timer variable becomes 10 or more, the process proceeds to step SC05.

  In step SC05, 0 is assigned to the timer variable.

  In step SC07, command processing is performed. The CPU 404 of the first sub control unit 400 determines whether a command has been received from the main control unit 300. When a random number acquisition error command is received, the LED 2 of the notification unit 259 mounted on the sub control board 221 is turned on as shown in FIG.

  In step SC09, an effect control process is performed. For example, when there is a new command in SC07, the effect data corresponding to this command is read from the ROM 406, and the effect data is updated when the effect data needs to be updated.

  In step SC10, when there is a command for controlling the shutter 163 in the effect data read in step SC09, shutter control corresponding to this command is performed via the drive circuit 430.

  In step SC11, when there is a command to the sound source IC 418 in the effect data read in step SC09, this command is output to the sound source IC 418.

  In step SC13, when there is a command to the various lamps 420 in the effect data read in step SC09, this command is output to the drive circuit 422.

  In step SC15, when there is a control command to be transmitted to the second sub-control unit 500 in the effect data read in step SC09, the control command is set to be output, and the process returns to step SC03.

  Next, the command reception interrupt process of the first sub-control unit 400 will be described using FIG. This command reception interrupt process is a process executed when the first sub-control unit 400 detects a strobe signal output from the main control unit 300.

  In step SD01 of the command reception interrupt process, the command output from the main control unit 300 is stored as an unprocessed command in a command storage area provided in the RAM 408.

  Next, the first sub control unit timer interrupt process executed by the CPU 404 of the first sub control unit 400 will be described with reference to FIG. The first sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms). Execute in the cycle.

  In step SE01 of the timer interruption process of the first sub control unit 400, 1 is added to the value of the timer variable storage area of the RAM 408 described in step SC03 in the first sub control unit main process shown in FIG. Stored in the original timer variable storage area. Therefore, in step SC03, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  In step SE03 of the first sub-control unit timer interrupt process, transmission of a control command to the second sub-control unit 500 set in step SC15, an effect random number update process, and the like are performed.

<Processing of second sub-control unit 500>

FIG. 7B is a flowchart of command reception interrupt processing of the second sub control unit 500. FIG. 8C is a flowchart of the timer interrupt process of the second sub control unit 500. FIG. 4D is a flowchart of the image control process of the second sub control unit 500.

  First, in step SF01 in FIG. 9A, various initial settings are performed. When power is turned on, an initialization process is first executed in SF01. In this initialization process, input / output port initialization, storage area initialization in the RAM 508, and the like are performed.

  In step SF03, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to step SF05.

  In step SF05, 0 is assigned to the timer variable.

  In step SC07, command processing is performed. The CPU 504 of the second sub control unit 500 determines whether a command has been received from the CPU 404 of the first sub control unit 400.

  In step SF09, an effect control process is performed. For example, if there is a new command in step SF07, processing such as reading the production data corresponding to this command from the ROM 506 is performed, and if the production data needs to be updated, the production data is updated.

  In step SF13, if there is an image control command in the effect data read in step SF09, image control corresponding to this command is performed (details will be described later), and the process returns to step SF03.

  Next, the command reception interrupt process of the second sub control unit 500 will be described with reference to FIG. This command reception interrupt process is a process executed when the second sub control unit 500 detects the strobe signal output from the first sub control unit 400.

  In step SG01 of the command reception interrupt process, the command output from the first sub-control unit 400 is stored as an unprocessed command in a command storage area provided in the RAM 508.

  Next, the second sub control unit timer interrupt process executed by the CPU 504 of the second sub control unit 500 will be described with reference to FIG. The second sub-control unit 500 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and a timer interrupt process is performed in response to this timer interrupt. Execute in the cycle.

  In step SH01 of the timer interrupt process of the second sub control unit 500, 1 is added to the value of the timer variable storage area of the RAM 508 described in step SF03 in the second sub control unit main process shown in FIG. Stored in the original timer variable storage area. Therefore, in step SF03, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  In step SH02 of the second sub control unit timer interrupt process, an operation state determination process is performed. In this operation status determination process, for example, the operation status of the VDP 534 (specifically, the status of the VSINC interrupt), the status of communication with the first sub-control unit 400, and the like are determined. The notification mode at the time of abnormality is implemented in LED4 and LED5 of the notification unit 246.

  In step SH03 of the second sub control unit timer interrupt process, various update processes are performed.

  Next, the image control process in step SF13 in the main process of the second sub-control unit 500 will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of image control processing.

  In step SI01, an instruction to transfer image data is issued. Here, the CPU 504 first swaps the designation of the display areas A and B in the VRAM 536. As a result, an image of one frame stored in the display area not designated as the drawing area is displayed on the effect image display device 157. Next, the CPU 504 sets ROM coordinates (transfer source address of the ROM 506), VRAM coordinates (transfer destination address of the VRAM 536), and the like in the attribute register of the VDP 534 based on the position information table, and then the image from the ROM 506 to the VRAM 536. Set an instruction to start data transfer. The VDP 534 transfers the image data from the ROM 506 to the VRAM 536 based on the command set in the attribute register. Thereafter, the VDP 534 outputs a transfer end interrupt signal to the CPU 504.

  In step SI03, it is determined whether or not a transfer end interrupt signal is input from VDP 534. If a transfer end interrupt signal is input, the process proceeds to step SI05. Otherwise, a transfer end interrupt signal is input. Wait for it.

  In step SI05, parameters are set based on the production scenario configuration table and attribute data. Here, in order to form a display image in the display area A or B of the VRAM 536 based on the image data transferred to the VRAM 536 in step SI01, the CPU 504 includes information on the image data constituting the display image (coordinate axes and image sizes of the VRAM 536). , VRAM coordinates (arrangement coordinates, etc.) are instructed to the VDP 534. The VDP 534 performs parameter setting according to the attribute based on the instruction stored in the attribute register.

  In step SI07, a drawing instruction is performed. In this drawing instruction, the CPU 504 instructs the VDP 534 to start drawing an image. The VDP 534 starts drawing an image in the frame buffer in accordance with an instruction from the CPU 504.

  In step SI09, it is determined whether or not a generation end interrupt signal from the VDP 534 is input based on the end of image drawing. If the generation end interrupt signal is input, the process proceeds to step SI11. If not, the generation end interrupt signal is determined. Wait for input.

  In step SI11, a scene display counter which is set in a predetermined area of the RAM 508 and counts how many scene images have been generated is incremented (+1), and the process ends.
