<Main control circuit>
Next, the main control circuit 91 configured by the main control board 71 will be described with reference to FIG.

FIG. 13 is a block diagram showing a configuration example of the main control circuit 91 of the pachi-slot machine 1.

The main control circuit 91 has a microcomputer 92 installed on the main control board 71 as a main component. The microcomputer 92 includes a main CPU 93, a main ROM 94, and a main RAM 95.

The main ROM 94 is for transmitting various control commands (commands) to the control program executed by the main CPU 93 (for example, the program for executing the internal lottery process described above), the data table, and the sub control circuit 721. Data etc. are stored. The main RAM 95 is provided with a storage area for storing various data such as an internal winning combination determined by executing a control program.

The clock pulse generation circuit 96 and the frequency divider 97 generate a clock pulse. The main CPU 93 executes a control program based on the generated clock pulse. The random number generator 98 generates random numbers in a predetermined range (for example, 0 to 65535). The sampling circuit 99 extracts one value from the generated random numbers.

The main CPU 93 counts the number of times a pulse is output to the stepping motors of the reels 3L, 3C, and 3R after detecting the reel index. As a result, the main CPU 93 manages the rotation angles of the reels 3L, 3C, and 3R (mainly, how many symbols the reels have rotated).

The reel index is information indicating that the reel has made one revolution. This reel index is provided, for example, with an optical sensor having a light emitting portion and a light receiving portion, and is provided at a predetermined position on each reel 3L, 3C, 3R, and the light emitting portion and the light receiving portion are connected by rotation of each reel 3L, 3C, 3R. Detection is performed by a reel position detection unit (not shown) provided with a detection piece interposed between them.

Here, the management of the rotation angle of each reel 3L, 3C, 3R will be specifically described. The number of pulses output to the stepping motor is counted by a pulse counter provided in the main RAM 95. Then, every time the output of a predetermined number of pulses (for example, 16 times) required for rotation of one symbol is counted by the pulse counter, the symbol counter provided in the main RAM 95 is added one by one. The symbol counter is provided according to each reel 3L, 3C, 3R. The value of the symbol counter is cleared when the reel index is detected by the reel position detection unit (not shown).

That is, in the present embodiment, by managing the symbol counter, it is possible to manage how many symbols have been rotated since the reel index was detected. Therefore, the position of each symbol of each reel 3L, 3C, 3R is detected with reference to the position where the reel index is detected.

Each symbol within the range up to is a symbol that can be stopped in the middle of the reel display window 4.

<Secondary control circuit>
Next, the sub-control circuit 721 configured by the sub-control board 72 will be described with reference to FIG.

FIG. 14 is a block diagram showing a configuration example of the sub-control circuit 721 of the pachi-slot machine 1.

The sub control circuit 721 is electrically connected to the main control circuit 91, and performs processing such as determination and execution of the effect content based on the command transmitted from the main control circuit 91. The sub control circuit 721 is basically configured to include a sub CPU 722 and a sub RAM 723.

The sub CPU 722 controls the output of sound and light according to the control program stored in the ROM cartridge board 86 in response to the command transmitted from the main control circuit 91. The ROM cartridge board 86 is basically composed of a program storage area and a data storage area.

The control program executed by the sub CPU 722 is stored in the program storage area. For example, in the control program, a main board communication task for controlling communication with the main control circuit 91 and an effect registration task for extracting an effect random value and determining and registering an effect content (effect data). Is included. Further, a lamp control task for controlling the output of light from a light source such as a light emitting display device 11 and a voice control task for controlling sound output by the speakers 20L and 20R are included based on the determined effect content.

The data storage area includes a storage area for storing various data tables and a storage area for storing the effect data constituting each effect content. Further, a storage area for storing sound data related to BGM and sound effects, a storage area for storing lamp data related to a pattern of turning on and off light, and the like are included.

The sub RAM 723 is composed of a DRAM (Dynamic Random Access Memory) and a SRAM (Static Random Access Memory). The DRAM is a work RAM as a volatile storage means. The SRAM is a backup RAM as a non-volatile storage means backed up by a backup power source. When the power is turned off, the backup area composed of the SRAM of the sub RAM 723 can store the data held at the time of the power off, and is said to be the same when the power is turned on (when the power is turned off and restored) and after the power is turned on. The data in the backup area is available. Further, in the DRAM of the sub RAM 723, a storage area for registering the determined effect content, a storage area for storing various data such as an internal winning combination transmitted from the main control circuit 91, and position information of the volume switch 87 are stored. A storage area for storing data and other data that is not allocated to the backup area (data that can be erased even when the power is off) is provided. Further, the error information history area and the threshold value storage area related to the CMOS threshold value, which will be described later, are allocated to the backup area.

Further, the sub CPU 722 outputs sounds such as BGM by the speakers 20L and 20R according to the sound data specified by the effect content. Further, the sub CPU 722 controls the lighting and extinguishing of the light source of the light emission display device 11 according to the lamp data designated by the effect content.

The sub CPU 722 is connected to the volume switch 87. The volume switch 87 is an example of a first contact means (also referred to as a multi-contact means) having a plurality of contacts. The volume switch 87 is an operation switch for adjusting the volume, and the volume of the sound output via the speakers 20L and 20R can be adjusted by the sub CPU 722 in a plurality of stages. The attribute of the sound whose volume stage can be adjusted by the sub CPU 722 by the volume switch 87 is arbitrary, and is, for example, a staging sound, BGM, or the like. Further, the sound whose volume stage can be adjusted by the sub CPU 722 by the volume switch 87 may be all sounds other than a predetermined warning sound (error sound, etc.).

In the present embodiment, when the setting switch 56 is in the off state, the sub CPU 722 outputs via the speakers 20L and 20R based on the change in the conduction state (which contact is conducting) of the volume switch 87. Performs processing (volume setting processing) to set the stage of the volume of the sound to be played. In the present embodiment, as an example, the volume stage is three stages of "LOW", "MIDDLE", and "HIGH", but it may be two stages or four or more stages. In this case, the number of contacts of the volume switch 87 is set according to the number of adjustable steps. An example of the volume setting process will be described later with reference to FIG. 26 and the like.

Further, in the present embodiment, when the setting switch 56 is in the ON state, the sub CPU 722 has information related to the determination of an illegal medal based on the change in the position of the volume switch 87 (which contact is conducting). Performs a process (CMOS threshold setting process) for changing the CMOS threshold (described later) used for generation (for example, alarm output). An example of this CMOS threshold setting process will be described later with reference to FIG. 25 and the like.

<Slide switch circuit configuration>
FIG. 15 is a diagram showing an example of the circuit configuration of the volume switch 87. In FIG. 15, the volume switch 87 is, for example, in the form of a slide switch and has three contacts 870A, 870B, 870C. The movable contact 871 contacts any of the contacts 870A, 870B, and 870C. That is, when the movable portion (not shown) of the volume switch 87 is slid, the movable contact 871 is displaced (transitioned) between the positions (states) in contact with any of the contacts 870A, 870B, and 870C. In this case, the sub-control circuit 721 has a position where the movable contact 871 contacts the contact 870A (hereinafter, also referred to as a “first conduction position”) and a position where the movable contact 871 contacts the contact 870B (hereinafter, “second conduction position”). The volume is based on the on or off state of the input ports 721A to 721C between the position (also referred to as "position") and the position where the movable contact 871 contacts the contact 870C (hereinafter, also referred to as "third conduction position"). The position of the switch 87 (which of the first conduction position to the third conduction position) can be determined. For example, in the first conduction position, the input ports 721A are in the off state and the input ports 721B and 721C are in the on state, and in the second conduction position, the input ports 721B are in the off state and the input ports 721A and 721C are in the on state. At the conduction position, the input port 721C is in the off state, and the input ports 721A and 721B are in the on state.

Note that FIG. 15 is merely an example, and the circuit configuration of the volume switch 87 is arbitrary as long as each conduction state (that is, the position of the volume switch 87) can be discriminated by the sub CPU 722.

<Circuit configuration of medal selector>
Next, the circuit configuration of the medal selector 201 will be described with reference to FIG.

FIG. 16 is a block diagram showing a circuit configuration example of the medal selector 201.

As shown in FIG. 16, the medal selector 201 includes a camera unit 209, a medal solenoid 208, and a double photo sensor 502.

Further, the medal selector 201 is connected to the main control board 71 via the door relay terminal plate 68. Further, the medal selector 201 is connected to the sub-control board 72 via the sub-relay board 61. That is, the medal selector 201 is electrically connected to the main control circuit 91 and the sub control circuit 721.

The main control circuit 91 can set the medal solenoid 208 of the medal selector 201 to the ON state or the OFF state. That is, the main control circuit 91 can move the select plate 207 to the guide position or the discharge position.

Specifically, when the pachi-slot machine 1 is in a state where medals can be inserted, the main control circuit 91 outputs a medal insertion signal having the content that the medals can be inserted. Further, the main control circuit 91 outputs a medal insertion signal having a content that the pachi-slot machine 1 cannot insert medals when the pachi-slot machine 1 is not in a state where medals can be inserted. Here, "outputting a medal insertion signal with contents that can be inserted" means that the signal line between the devices connected to the main control circuit 91 (medal solenoid 208 in this embodiment) is set to the ON state. be. Further, "outputting a medal insertion signal having a content that cannot be inserted" means setting the signal line between the devices connected to the main control circuit 91 (the medal solenoid 208 in this embodiment) to the OFF state. .. When the medal solenoid 208 detects that the signal line between the main control circuit 91 and the medal solenoid 208 is in the ON state, the medal solenoid 208 sets itself in the ON state. Further, when the medal solenoid 208 detects that the signal line between the main control circuit 91 and the medal solenoid 208 is in the OFF state, the medal solenoid 208 sets itself in the OFF state.

The double photo sensor 502 of the medal selector 201 is connected to the main control board 71 via the door relay terminal plate 68. The double photo sensor 502 is the first photo sensor 50.
3 and a second photo sensor 504.

As shown in FIG. 6, the first photo sensor 503 is provided in the vicinity of the medal outlet portion 204c in the base plate portion 204 of the medal selector 201. The first photosensor 503 has a photodiode (not shown) embedded in the medal rail 210 of the base plate portion 204, and a light emitter (not shown) that irradiates the photodiode with light (infrared light). .. The photodiode and the illuminant face each other at a distance of more than the thickness of the medal, and when the select plate 207 is in the guide position, the medal moving on the medal rail 210 can pass between the photodiode and the illuminant. It has become.

The light emitter always emits a predetermined amount of light. When the photodiode receives a predetermined amount of light or more from the light emitter, the first photosensor 503 outputs a high-level signal. On the other hand, when the amount of light received by the photodiode becomes less than the predetermined amount of light, the first photosensor 503 outputs a low-level signal (medal detection signal). Therefore, when the medal passes between the photodiode and the light emitting body and blocks the light of the light emitting body, the first photo sensor 503 outputs the medal detection signal.

The second photo sensor 504 moves on the medal rail 210 from the first photo sensor 503 in the vicinity of the medal exit portion 204c in the base plate portion 204 of the medal selector 201 and in the vicinity of the first photo sensor 503. It is provided on the downstream side in the moving direction of the medal. Since the other points are the same as those of the first photo sensor 503, the description thereof will be omitted.

In the present embodiment, the first photosensor 503 and the second photosensor 504 constituting the double photosensor 502 block the light of the light emitter by passing the medal between the photodiode and the light emitter. , A mode of adopting a shielding type sensor method for detecting a passing object (that is, a detection method for detecting by changing the state of a photodiode from an on state to an off state) has been described. However, the mode in which the medal is detected by the photodiode is not limited to this. For example, a so-called reflective sensor method is adopted in which a photodiode and a light emitter are arranged on the left and right or vertically, and the photodiode receives the light reflected by the medal that passes through the light of the light emitter to detect the passage of the medal. You may. Further, the first photosensor 503 may be a shielding type, the second photosensor 504 may be a reflective type, or vice versa, and these sensor methods may be appropriately selected and adopted depending on the position where the photodiode is arranged. good.

As described above, the first photo sensor 503 is provided near the medal exit portion 204c, and the second photo sensor 504 is provided downstream of the first photo sensor 503 on the medal rail 210. Therefore, in the first photo sensor 503 and the second photo sensor 504, the select plate 207 is in the guide position, and the medal moving to the medal outlet portion 204c (see FIG. 6) side is detected, but the select plate 207 is in the ejection position. In, medal shoot 20
The medal guided to 2 (see FIG. 6) is not detected.

The medal detection signals output from the first photo sensor 503 and the second photo sensor 504 are input to the main control board 71 (main control circuit 91) via the door relay terminal plate 68. After the main CPU 93 (see FIG. 13) of the main control board 71 detects the medal detection signal input from the first photo sensor 503, the medal detection signal input from the second photo sensor 504 is detected within a predetermined time. When detected, the number of inserted medals is incremented by 1 to the value of the inserted number counter, which is a counter provided for the main CPU 93 to count the number of inserted medals. When the value of the inserted number counter is the maximum value (for example, 3), 1 is added to the value of the credit counter, which is a counter provided for the main CPU 93 to count the number of credited medals.

When the credit counter has a maximum value (for example, 50), the main control circuit 91 sets the medal solenoid 208 of the medal selector 201 to the OFF state. As a result, the select plate 207 (see FIG. 6) is positioned at the “discharge position”, medals cannot be inserted, and the medals inserted after the credit counter reaches the maximum value are placed in the medal shoot 202 (see FIG. 4). Guide the medal from the medal payout exit 18 (see FIG. 2) to the medal tray 19.

The main control circuit 91 sets the medal solenoid 208 of the medal selector 201 to the OFF state even after the start lever 23 is operated by the player in the unit game.

Further, when the main CPU 93 receives the medal detection signal in the order of the medal detection signal input from the second photo sensor 504 and the medal detection signal input from the first photo sensor 503, the medal is placed on the medal rail 210. It detects that a so-called retrograde error has occurred in which the vehicle moves in a movement direction different from the proper movement direction (reverse).

Further, even after a certain period of time has elapsed from the detection of the medal detection signal by the main CPU 93, the medal detection signal continues to be output from either or both of the first photo sensor 503 and the second photo sensor 504. In some cases, or if the medal detection signal from the second photosensor 504 cannot be detected even after a certain period of time has passed since the medal detection signal from the first photosensor 503 was detected, the medal stays on the medal rail 210, so-called. Detects that a medal jam error has occurred.

When the main control circuit 91 (main CPU 93) detects a retrograde error or a medal jam error, the game is forcibly interrupted, and an error code corresponding to the content of the detected error is displayed on the 7-segment display 6 (see FIG. 2). Is displayed, and an error command corresponding to the content of the detected error is transmitted to the sub control circuit 721 to notify the error via the sub control circuit 721. For example, when the sub control circuit 721 provides a sub 7-segment display (not shown) for controlling the display, the sub 7-segment display may display a predetermined display.

The sub-control circuit 721 receives the color determination determination result, the marking determination determination result, and various signals and commands described later from the control LSI 234 of the medal selector 201.

The camera unit 209 includes a control LSI 234, a CMOS image sensor 232, and an LED 233. The control LSI 234 of the camera unit 209 is composed of an ASIC (Application Specific Integrated Circuit) and is electrically connected to the CMOS image sensor 232 and the LED 233. The control LSI 234 controls the light emission of the LED 233. Further, the control LSI 234 determines whether or not the object moving on the medal rail 210 is a regular medal based on the image data output from the CMOS image sensor 232, and determines the determination result from the UART 252, which will be described later, on the auxiliary relay board. It is transmitted to the sub-control board 72 (sub-control circuit 721) via 61.

The CMOS image sensor 232 includes an exposure time setting mechanism that sets the exposure time (shutter speed) in 1 to 25 steps. The exposure time is set to be extended by 7 μs for each step up. In the present embodiment, the initial value of the exposure time (value when the power of the pachi-slot machine 1 is turned on) is set to step 10, that is, 70 μsec. Therefore, in the present embodiment, the exposure time can be set in the range of 70 μsec to a maximum of 175 μsec (exposure time corresponding to step 25).

The CMOS image sensor 232 used in the present embodiment is a CMOS image sensor having a resolution of 648 × 488 pixels and a frame rate of 240 fps (Frames Per Second).

Further, the control LSI 234 is electrically connected to the notification LED 206c via the GPIO250. The notification LED 206c is turned on and off in response to an instruction from the control LSI 234.

Further, the control LSI 234 is electrically connected to the initialization switch 206d, the color switch 206e, and the marking switch 206f via the GPIO250. When the initialization switch 206d is operated (turned on) while the power is on, the control LSI 234 performs the initialization process. In the initialization process, the control LSI 234 deletes various parameters and templates stored in the SRAM 243 and the flash memory 244, which will be described later, and sets (reset) the initial values in these.

The color switch 206e can be set to the ON / OFF state. When the color switch 206e is set to the ON state, the control LSI 234 enables color determination, and the value of the color determination result included in the determination completion command described later is set to "1" (determination OK) according to the actual determination result. Or, set it to "0" (judgment NG). On the other hand, when the color switch 206e is set to the OFF state, the control LSI 234 invalidates the color determination, and the value of the color determination result included in the determination completion command described later is set to "1" (determination) regardless of the actual determination result. Set to OK). That is, the color switch 206e is set to the ON state when the color determination is enabled, and is set to the OFF state when the color determination is disabled.

The marking switch 206f can be set to an ON / OFF state. When the marking switch 206f is set to the ON state, the control LSI 234 enables the marking determination, and the value of the marking determination result included in the determination completion command described later is set to "1" (determination OK) according to the actual determination result. Or, set it to "0" (judgment NG). On the other hand, when the marking switch 206f is set to the OFF state, the control LSI 234 invalidates the marking determination, and the value of the marking determination result included in the determination completion command described later is set to "1" (determination) regardless of the actual determination result. Set to OK). That is, the marking switch 206f is set to the ON state when the marking determination is enabled, and is set to the OFF state when the marking determination is disabled.

In the present embodiment, the control LSI 234 sets the enable / disable of the color determination according to the ON / OFF state of the color switch 206e at the time of turning on the power, and also corresponds to the ON / OFF state of the marking switch 206f at the time of turning on the power. Set whether to enable / disable the marking judgment. Even if these switches are operated after the power is turned on, the validity / invalidity of the color judgment and the marking judgment set according to the state of the switch at the time of turning on the power is not changed. The control LSI 234 acquires the ON / OFF state of the initialization switch 206d, the color switch 206e, and the marking switch 206f in a predetermined cycle (for example, 10 msec cycle). It should be noted that this cycle is set shorter than the cycle for transmitting the medal selector non-operation command described later.

<Circuit configuration of control LSI>
Next, the circuit configuration of the control LSI 234 will be described with reference to FIG.

FIG. 17 is a block diagram showing a circuit configuration example of the control LSI 234.

The control LSI 234 includes a host controller 241, an image recognition DSP (digital signal processor) circuit 242, a SRAM (Static Random Access Memory) 243 to which a backup power supply (not shown) is connected, a flash memory 244, and an ISP (Image Signal Process). ) The circuit 245 and the medal counting circuit 246 are provided. Further, the control LSI 234 includes a color recognition circuit 247, a fisheye correction scaler circuit 248, an image recognition accelerator circuit 249, a GPIO (General Purpose Input / Output) 250, and a UART (Universal Sync synchro oscillator 25). The devices constituting these control LSIs 234 are connected to each other via a bus, and in the control LSI 234 of the present embodiment, AXI (Advanced eXtensible Interface) is adopted as a bus protocol.

Further, the control LSI 234 includes an ISI (Image Sensor Interface) circuit 251. The ISI circuit 251 is electrically connected to the CMOS image sensor 232 and the ISP circuit. The ISI circuit 251 converts the image data transmitted from the CMOS image sensor 232 by the LVDS (Low voltage differential signaling) method into an RGB bayer image and outputs the image data. At this time, a unique image ID is attached to the RGB image output from the ISI circuit 251. This image ID is inherited by the data after being subjected to various image conversions described later. Therefore, each determination result can be associated with the image ID inherited from the data related to various determinations described later. That is, when a medal appears in the RGB image, these determination results for this medal can be associated with each other.

The operation of each part of the control LSI 234 is known from, for example, Japanese Patent Application Laid-Open No. 2018-180593, and detailed description thereof will be omitted here.

<Commands sent and received between the medal selector and the sub control circuit>
Here, with reference to FIG. 18, commands transmitted and received between the medal selector 201 and the sub-control circuit 721 will be described. FIG. 18 is a list of commands transmitted / received between the medal selector 201 and the sub-control circuit 721.

[Command sent by medal selector]
First, a command transmitted by the medal selector 201 to the sub-control circuit 721 will be described. As shown in FIG. 18, the command includes a start completion command, a determination completion command, a medal selector error command, a medal selector no operation command, an ACK command, and a NAK command. Each command is configured to include a 2-byte transmission counter (CNT) and a parameter consisting of DAT0 to DAT6. In this embodiment, DAT0 to DAT6 are 1 byte (bits 0 to 7) of data, respectively. Further, the data length of various commands is set to 9 bytes including the transmission counter, and this data length can be set as appropriate.

The initial value of the transmission counter (CNT) in the command transmitted by the medal selector 201 is set to the number of times the medal selector 201 is activated. The value of this transmission counter is incremented by 1 each time the medal selector 201 transmits a command to the sub-control circuit 721.

[Startup complete command]
The activation completion command is transmitted after the power is turned on to the medal selector 201 and the activation process is completed. The value of bit 0 of DAT0 of the start completion command indicates whether or not initialization has been performed. “0” indicates “without initialization”, and “1” indicates “with initialization”. Here, when the control LSI 234 of the medal selector 201 is initialized while the power is on, the value of the activation initialization flag storage area of the flash memory 244 is set to "1". Then, when the power is turned on and the start completion command is transmitted, the control LSI 234 refers to the start initialization flag storage area of the flash memory 244, and depending on the stored value, sets the start completion command DAT0. Set the value of bit 0. When the value of bit 0 of DAT0 of the activation completion command is "1", that is, when "1" is set in the value of the initialization flag storage area for activation at startup, the medal selector 201 is transmitted from the sub-control circuit 721. Upon receiving the ACK command for the startup completion command, the control LSI 234 sets the value of the startup initialization flag storage area to "0".

Further, the value of bit 1 of DAT0 of the activation completion command indicates whether the color determination is valid or invalid at the time of command transmission. A value "0" indicates "color determination invalid", and a value "1" indicates "color determination valid". When "color determination is valid", it means that the color template has been created at the time of command transmission and the color switch 206e at startup is in the ON state. In other cases, "color judgment is invalid". Further, the value of bit 2 of DAT0 of the activation completion command indicates whether the marking determination is valid or invalid at the time of command transmission. A value "0" indicates "invalid marking determination", and a value "1" indicates "valid marking determination". When "engraving determination is valid", it means that the engraving template has been created at the time of command transmission and the engraving switch 206f at the time of activation is in the ON state. In other cases, the stamp judgment is invalid.

DAT1 of the start completion command indicates the ON / OFF state of various switches at the time of command transmission. The value of bit 0 indicates the ON / OFF state of the initialization switch 206d, the value of bit 1 indicates the ON / OFF state of the color switch 206e, and the value of bit 2 indicates the ON / OFF state of the marking switch 206f. In any bit, "0" indicates "OFF state" and "1" indicates "ON state".

[Judgment completion command]
The determination completion command includes a transmission counter (CNT) and parameters indicating a determination result of circular detection, a determination result of color determination, and a determination result of marking determination. The value of DAT0 of the determination completion command indicates the determination result of circular detection, the value of DAT1 indicates the determination result of color determination, and the value of DAT2 indicates the determination result of marking determination. In any bit, "0" indicates "NG" (that is, "determination NG"), and "1" indicates "OK" (that is, "determination OK").

[Medal Selector Error Command]
The medal selector error command is transmitted when the medal selector 201 detects various errors. This command includes a transmission counter (CNT) and a parameter indicating the type of error occurring when the command is transmitted. The value of DAT0 of the medal selector error command is set to 0-6. “0” indicates “no error”, “1” indicates “foreign matter detection error”, and “2” indicates “cover opening error”. Further, "3" indicates "cleaning error", "4" indicates "color template generation error", "5" indicates "engraving template generation error", and "6" indicates "CMOS hard error". ". When various errors are detected, the control LSI 234 of the medal selector 201 stores the error contents (1 to 6) in the error storage area (initial value “0”) provided in the SRAM 243. The content of the error stored in the SRAM 243 is deleted when the medal selector 201 receives the error cancellation command described later from the sub-control circuit 721 (the initial value "0" is stored).

[Medal selector no operation command]
The medal selector non-operation command is periodically transmitted from the medal selector 201 to the sub-control circuit 721. The medal selector non-operation command includes a transmission counter (CNT).

Further, the value of bit 0 of DAT0 of the medal selector non-operation command indicates whether or not initialization has been performed. “0” indicates “without initialization”, and “1” indicates “with initialization”. Here, when the control LSI 234 of the medal selector 201 is initialized while the power is on, the SRAM is
Set "1" to the value of the initialization flag storage area for no operation of 243. Then, when transmitting the medal selector non-operation command, the control LSI 234 refers to the non-operation initialization flag storage area of the SRAM 243, and according to the stored value, bit 0 of the DAT0 of the medal selector non-operation command. Set the value of. When the value of bit 0 of DAT0 of the medal selector non-operation command is "1", that is, when the value of the initialization flag storage area for no operation is set to "1", the medal selector 201 is transmitted from the sub-control circuit 721. Upon receiving the ACK command for the medal selector non-operation command, the control LSI 234 sets the value of the non-operation initialization flag storage area to "0".

The other medal selector non-operation commands DAT0 and DAT1 are the same as the activation completion commands DAT0 and DAT1, so the description thereof is omitted here. Further, the content of the error storage area (value of any of 0 to 6) of the above-mentioned SRAM 243 is set in DAT3 of the medal selector non-operation command. The content is the same as DAT0 of the medal selector error command.

The values of DAT3 and DAT4 of the medal selector non-operation command indicate the number of times the medal selector 201 is activated. The number of activations is stored in the flash memory 244, and 1 is added to the number of activations each time the medal selector 201 is activated. Specifically, the medal selector 201 has a control power supply management unit (not shown), and the control power supply management unit starts supplying a power supply voltage (power on) to the medal selector 201 and sets a preset voltage value. When the voltage exceeds the above, a reset signal is output to the control LSI 234. The control LSI 234 adds 1 to the number of activations based on the input of the reset signal. The medal selector 201 (control LSI 234) refers to the number of times the flash memory 244 is activated when the medal selector non-operation command is transmitted, and sets the values of DAT3 and DAT4. The number of activations is initialized to the initial value "0" by the initialization process performed by the control LSI 234 by the operation of the initialization switch 206d described above.

[ACK command, NAK command]
The ACK command is transmitted when the medal selector 201 can normally receive the command transmitted from the sub-control circuit 721. The NAK command is transmitted when the medal selector 201 cannot normally receive the command transmitted from the sub-control circuit 721. The ACK command and the NAK command include a transmission counter (CNT). Further, the values of DAT0 and DAT1 of the ACK command and the NAK command indicate the values of the transmission counter included in the command transmitted from the sub-control circuit 721.

[Command sent by sub-control circuit]
Next, a command transmitted by the sub-control circuit 721 to the medal selector 201 will be described. As shown in FIG. 18, the command includes an error release command, an input status command, an ACK command, and a NAK command. Each command is configured to include a 2-byte transmission counter (CNT) and a parameter consisting of DAT0 to DAT6. In the present embodiment, each of DAT0 to DAT6 is 1 byte (bits 0 to 7) of data. Further, the data length of various commands is set to 9 bytes including the transmission counter, and this data length can be set as appropriate.

The initial value of the transmission counter (CNT) in the command transmitted by the sub-control circuit 721 is set to a random number acquired when the command is first transmitted after the sub-control circuit 721 is activated. In addition, in order to generate this random number, a dedicated random number generation process (soft random number) for generating this random number, or a device may be provided, or a random number generation used for determining the mode of production may be provided. Processing or the device may be used.

[Error release command]
The error release command is transmitted when the error release condition generated in the medal selector 201 is satisfied in the medal selector command transmission process. However, the establishment of the error cancellation condition is not whether or not the error generated in the medal selector 201 is actually canceled, but whether or not the condition for transmitting the error cancellation command is satisfied.

[Input status command]
The throwing state command is transmitted in a predetermined cycle or in the medal selector command transmission process. The value of DAT0 of the insertion state command indicates whether or not the medal can be accepted. "1" indicates "acceptable" and "0" indicates "acceptable".

[ACK command, NAK command]
The ACK command is transmitted when the sub-control circuit 721 can normally receive the command transmitted from the medal selector 201. The NAK command is transmitted when the sub-control circuit 721 cannot normally receive the command transmitted from the medal selector 201. The ACK command and the NAK command include a transmission counter. Further, the values of DAT0 and DAT1 of the ACK command and the NAK command indicate the values of the transmission counter included in the command transmitted from the medal selector 201.

<Command transmission / reception sequence between medal selector and sub-control circuit>
Next, with reference to FIG. 19, an example of a command transmission / reception sequence between the medal selector and the sub-control circuit will be described. FIG. 19 is a diagram for explaining an example of a command transmission / reception sequence between the medal selector and the sub-control circuit.

When the power is turned on to the pachi-slot machine 1 and the medal selector 201 and the sub-control circuit 721 are activated, the medal selector 201 transmits an activation completion command to the sub-control circuit 721. At this time, when the number of activations stored in the flash memory 244 is "10", the value of the transmission counter (CNT) included in the activation completion command is "10".

Subsequently, the sub-control circuit 721 that has normally received the activation completion command transmits an ACK command to the medal selector 201. The value of the transmission counter included in this ACK command is a random number value acquired at the time of transmission, for example, "256". Further, the values of DAT0 and DAT1 of this ACK command are "10", which is the value of the transmission counter included in the received activation completion command.

Subsequently, in the example shown in FIG. 19, the medal selector 201 transmits a medal selector no operation command to the sub-control circuit 721. The value of the transmission counter included in this medal selector non-operation command is "11", which is the initial value "10" plus one.

Subsequently, the sub-control circuit 721 that has normally received the medal selector no operation command transmits the ACK command to the medal selector 201. The value of the transmission counter included in this ACK command is "257", which is the initial value "256" plus one. Further, the values of DAT0 and DAT1 of this ACK command are "11", which is the value of the transmission counter included in the received medal selector non-operation command.

Subsequently, in the example shown in FIG. 19, the sub-control circuit 721 transmits a closing state command to the medal selector 201. The value of the transmission counter included in this input state command is "258", which is obtained by adding 1 to "257". Here, when the medal selector is rebooted (restarted) for some reason and the ACK command for the input status command is transmitted after the restart, the transmission counter included in this ACK command becomes the initial value again. In this case, the number of activations is "1"
Since it becomes "1", the transmission counter included in the ACK command becomes "11".

In the present embodiment, when the sub-control circuit 721 receives the ACK command from the medal selector 201, the value of the transmission counter included in the received ACK command is included in the command received from the medal selector 201 last time. It is determined whether or not it is equal to the value obtained by adding "1" to the value of the transmission counter. If it is determined that they are not equal, the error information history area provided in the sub RAM 723 contains "CMOS CNT" (hereinafter, may be referred to as "ACK count error") as the error content, and the current date as the occurrence date and time. And memorize the time.

In the example shown in FIG. 19, the value of the transmission counter included in the received ACK command is "11". Further, the value obtained by adding "1" to the value "11" of the transmission counter included in the medal selector non-operation command, which is the command received from the medal selector 201 last time, is "12". Therefore, the sub CPU 722 determines that these values are not equal. Therefore, the sub CPU 722 stores "CMOS CNT" (ACK count error) as the error content and the current date and time as the occurrence date and time in the error information history area provided in the sub RAM 723.

Further, the medal selector 201 transmits a command to the sub-control circuit 721 at a cycle of 500 msec. For example, in the example shown in FIG. 19, the medal selector non-operation command is transmitted to the sub-control circuit 721 500 msec after the activation completion command is transmitted to the sub-control circuit 721. The cycle for transmitting a command from the medal selector 201 to the sub-control circuit 721 can be appropriately set.

<Various processing performed by the sub control circuit>
Next, among the various processes performed by the sub control circuit 721 (sub CPU 722), various processes related to the medal selector 201 and the volume switch 87 will be described with reference to FIGS. 20 and 20 and later.

[Power-on process]
The power-on process will be described with reference to FIG. FIG. 20 is a flowchart showing an example of the power-on process.

In the power-on process, first, the sub CPU 722 performs an initialization process (S101). Specifically, the sub CPU 722 initializes each driver and starts the kernel (kernel or operating system), and sets the volume stage (see FIG. 28) according to the state of the volume switch 87.

Next, the sub CPU 722 adds 1 to (the value of) the sub power-on counter provided in the sub RAM 723 (S102). Specifically, the sub control circuit 721 has a sub control power supply management unit (not shown), and the sub control power supply management unit starts supplying a power supply voltage (power on) to the sub control circuit 721 and sets it in advance. When the voltage value exceeds the value, a reset signal is output to a reset terminal (not shown) of the sub CPU 722. The sub CPU 722 adds 1 to the sub power-on counter (value) based on the input of the reset signal. The sub power-on counter receives a start-up completion command in which the medal selector 201 is initialized and the sub-control circuit 721 is initialized from the medal selector 201 (1 is set in bit 0 of DAT0). Is cleared (0 is set).

Then, the sub CPU 722 ends the power-on process.

[Processing when no operation command is received]
The non-operation command reception processing will be described with reference to FIG. FIG. 21 is a flowchart showing an example of processing when a non-operation command is received. When the sub CPU 722 receives the non-operation command from the main control circuit 91, the sub CPU 722 performs the non-operation command reception processing.

Here, the commands transmitted from the main control circuit 91 to the sub control circuit 721 include an error command, a start command, a winning operation command, a medal insertion command, and a non-operation command.

The error command is transmitted from the main control circuit 91 to the sub control circuit 721 when the main control circuit 91 detects an error. The error command includes, for example, parameters indicating the contents of various errors detected by the main control circuit 91. The start command is transmitted from the main control circuit 91 to the sub control circuit 721 when the main control circuit 91 detects the operation of the player's start lever 23.

The winning operation command is transmitted from the main control circuit 91 to the sub control circuit 721 at a predetermined timing. The winning operation command includes, for example, parameters indicating the type of display combination, the flag related to the lock effect, the number of medals to be paid out, and the like. By receiving the winning operation command, the sub-control circuit 721 can recognize the symbol combination displayed along the winning determination line, and can determine the timing and the like for executing various effects. ..

The medal insertion command is a sub-control circuit from the main control circuit 91 when the re-game is activated or when the player inserts the medal (pressing the MAX bet button 14 or the 1-bet button 15 or inserting a medal into the medal insertion slot 13). Sent to 721. The medal insertion command includes the number of medals inserted and the credit insertion counter described later.

The non-operation command is transmitted when the main CPU 93 does not transmit all commands other than the above-mentioned non-operation command in the interrupt processing executed every predetermined time (for example, 1.1173 ms). For non-operation commands, various buttons (MAX bet button 14, 1-bet button 15, stop buttons 19L, 19C, 19R, etc.) are pressed, and the medal solenoid 208 is set to the ON state or OFF state. Contains information indicating whether it is set. It also contains information indicating whether the reset switch (not shown) is in the ON state or the OFF state.

In the non-operation command reception processing, the sub CPU 722 stores (stores) various parameters of the non-operation command received in the non-operation command storage area of the sub RAM 723 (S111). As a result, the sub CPU 722 can execute various processes according to the stored parameters. Then, the sub CPU 722 ends the non-operation command reception processing.

[Medal Selector Communication Task]
The medal selector communication task will be described with reference to FIG. FIG. 22 is a flowchart showing an example of the medal selector communication task. The sub CPU 722 executes the medal selector communication task when the setting switch 56 is in the off state after the power-on process.

In the medal selector communication task, first, the sub CPU 722 performs a 10 msec cycle wait process (S121). Specifically, the sub CPU 722 does not shift the process to step S122 until 10 msec elapses after the process shifts to step S121, and shifts the process to step S122 after 10 msec has elapsed. That is, the processing after step S122 of the medal selector communication task is performed every 10 msec.

Next, the sub CPU 722 determines whether or not there is received data in the medal selector reception buffer (S122). The medal selector reception buffer is provided in the sub RAM 723, and temporarily stores various commands and data transmitted from the medal selector 201 to the sub control circuit 721.

When it is determined in step S122 that there is no received data in the medal selector reception buffer (when the determination in S122 is NO), the sub CPU 722 shifts the process to step S121. On the other hand, when it is determined in step S122 that there is received data in the medal selector reception buffer (when the determination in S122 is YES), the sub CPU 722 performs the medal selector command reception process (S123). In the medal selector command reception process, the sub CPU 722 executes various processes according to the command received from the medal selector 201. The details of the medal selector command reception process will be described later.

Next, the sub CPU 722 performs the medal selector command transmission process (S124). In the medal selector command transmission process, the sub CPU 722 transmits various commands to the medal selector 201. The details of the medal selector command transmission process are not related to the present invention and are omitted here. After step S124, the sub CPU 722 shifts the process to step S121.

[Medal selector command reception processing]
The medal selector command reception process will be described with reference to FIG. 23. FIG. 23 is a flowchart showing an example of the medal selector command reception process.

In the medal selector command reception process, first, the sub CPU 722 determines whether or not the command received from the medal selector 201 is an activation completion command (S131).

When it is determined in step S131 that the received command is a start-up complete command (YES in S131), the sub CPU 722 performs a start-up complete command reception process (S132). Since the details of the processing at the time of receiving the start completion command are not related to the present invention, they are omitted here. After that, the sub CPU 722 ends the medal selector command reception process, and returns the process to step S124 of the medal selector communication task (see FIG. 22).

On the other hand, when it is determined in step S131 that the received command is not the activation completion command (NO determination in S131), the sub CPU 722 determines whether the command received from the medal selector 201 is the determination completion command (S133). ).

When it is determined in step S133 that the received command is a determination completion command (YES determination in S133), the sub CPU 722 performs a determination completion command reception process (S134). The details of the processing at the time of receiving the determination completion command will be described later. After that, the sub CPU 722 ends the medal selector command reception process, and returns the process to step S124 of the medal selector communication task (see FIG. 22).

On the other hand, when it is determined in step S133 that the received command is not a determination completion command (NO determination is made in S133), the sub CPU 722 determines whether or not the command received from the medal selector 201 is a medal selector error command (when it is determined that the command is not a medal selector error command). S135).

When it is determined in step S135 that the received command is a medal selector error command (YES determination in S135), the sub CPU 722 performs a medal selector error command reception processing (S136). Since the details of the medal selector error command reception processing are not related to the present invention, they are omitted here. After that, the sub CPU 722 ends the medal selector command reception process, and returns the process to step S124 of the medal selector communication task (see FIG. 22).

On the other hand, when it is determined in step S135 that the received command is not a medal selector error command (when the determination in S135 is NO), the sub CPU 722 determines whether the command received from the medal selector 201 is an ACK or NAK command. (S137).

When it is determined in step S137 that the received command is an ACK or NAK command (YES in S137), the sub CPU 722 performs ACK / NAK command reception processing (S138). In the ACK / NAK command reception processing, various processes are performed according to the received ACK / NAK command. As an example of various processes, when an ACK command for an error release command described later is received from the medal selector 201, the above-mentioned ACK count error may be registered in the error information history. After that, the sub CPU 722 ends the medal selector command reception process, and returns the process to step S124 of the medal selector communication task (see FIG. 45).

On the other hand, when it is determined in step S137 that the received command is not ACK or NAK (when the determination in S137 is NO), the sub CPU 722 determines whether the command received from the medal selector 201 is a medal selector non-operation command. (S139).

When it is determined in step S139 that the received command is a medal selector non-operation command (YES determination in S139), the sub CPU 722 performs a medal selector non-operation command reception processing (S140). Since the details of the processing when the medal selector non-operation command is received are not related to the present invention, they are omitted here. After that, the sub CPU 722 ends the medal selector command reception process, and returns the process to step S124 of the medal selector communication task (see FIG. 22).

On the other hand, when it is determined in step S139 that the received command is not a medal selector non-operation command (NO determination in S139), the sub CPU 722 ends the medal selector command reception process and performs the process in the medal selector communication task (FIG. FIG. 22) Step S
Return to 124.

[Processing when a judgment completion command is received]
The processing at the time of receiving the determination completion command will be described with reference to FIG. 24. FIG. 24 is a flowchart showing an example of processing when a determination completion command is received.

In the process at the time of receiving the determination completion command, the sub CPU 722 first registers the determination result in the queue (S151). Specifically, the sub CPU 722 has DAT0 (circular detection OK / NG), DAT1 (color determination OK / NG), and DAT2 (engraving determination OK /) of the determination completion command received from the medal selector 201 stored in the reception buffer. The value (data) of NG) is registered in the queue.

Here, the DRAM of the sub RAM 723 of the present embodiment is provided with a queue as shown in FIG. 25. The queue is an area in which data for 60 blocks of FIFO (First In, First Out: first-in, first-out) settings can be registered. The data in one block is composed of the data of the determination completion commands DAT0 to DAT2. If the data D61 in the 61st block is registered in the queue while the data for 60 blocks is registered in the queue, the data D1 registered in the queue first overflows from the queue and is discharged. Therefore, the determination result for the latest 60 medals is always registered in the queue. In the following description, the overflowing and discharging of data from the queue may be referred to as "queue overflow".

Next, the sub CPU 722 determines whether or not there is a queue overflow (S152). When it is determined that there is no queue overflow (when the determination in S152 is NO), the sub CPU 722 ends the processing of the current cycle. On the other hand, when it is determined that there is a queue overflow (YES in S152), the sub CPU 722 performs a queue registration check process (S153). In the queue registration check process, the sub CPU 722 performs circular detection, color determination, and circular detection in the data for 60 blocks registered in the queue (here, the data stored in one block is regarded as one data). The number of data including "0", that is, "NG (determination NG)" is counted in any one of the determination results of the marking determination. That is, the number of data as the counting result is the number of medals that are "decision NG", that is, "illegal medals" in any one of the determination results of the circle detection, the color determination, and the marking determination.

Next, the sub CPU 722 determines whether or not the number of data including the NG determination counted in step S153, that is, the number of illegal medals is equal to or greater than the CMOS threshold value (“5” in this embodiment) (S154). In this embodiment, the CMOS threshold value can be set in three stages of "5", "10", and "15". When it is determined that the number of data including the NG determination is not equal to or greater than the CMOS threshold value (when the determination in S154 is NO), the sub CPU 722 ends the processing of the current cycle. On the other hand, when it is determined that the number of data including the NG determination is equal to or greater than the CMOS threshold value (when the determination in S154 is YES), the sub CPU 722 outputs an alarm (S155). Specifically, the sub CPU 722 outputs a predetermined warning sound and / or warning sound via the speakers 20L and 20R. Then, the sub CPU 722 ends the process at the time of receiving the determination completion command, and returns the process to step S124 of the medal selector communication task (see FIG. 22).

The CMOS threshold value used in step S154 is stored in the backup area of the sub RAM 723. Further, the CMOS threshold value used in step S154 can be appropriately changed.

According to the determination completion command reception processing shown in FIG. 24, the sub control circuit 721 (sub CPU 722) transmits the determination result of the reception completion command to the sub RAM 103 in the determination completion command reception processing (see FIG. 24). Register in the provided queue (step S151). Next, when the queue overflows, the number of "judgment NG" among the judgment results registered in the queue is counted, and whether the value is equal to or higher than the CMOS threshold value ("5" in this embodiment). It is determined whether or not (steps S152 to S154).

Therefore, it is determined that the number of "judgment NG" in the judgment results registered in the queue is equal to or higher than the CMOS threshold value, that is, the number of illegal medals in the latest 60 inserted medals exceeds a predetermined amount. , It is possible to output an alarm when the queue overflows. Since the queue overflow is used, it is not necessary to add a process that specifically specifies the timing for the alarm output, and it is efficient to detect and notify that the inserted fraudulent medals exceed the predetermined amount. be able to. Further, when the number of "determination NG" in the determination results registered in the queue is equal to or greater than the CMOS threshold value, the sub CPU 102 can output an alarm (S155) to alert the surroundings. You can effectively prevent the use of illegal medals.

In the present embodiment, the number of "determination NG" in the determination results registered in the queue is counted when the queue overflows, but the present invention is not limited to this. For example, the NG counter may be updated every time the determination result is input, and an alarm output may be performed when the NG counter exceeds the CMOS threshold value. In this case, the NG counter may be incremented by "1" when the determination result is "determination NG", and may be decremented by "1" when the determination result is "determination OK". Alternatively, the NG counter may be incremented by "1" when the determination result is "determination NG" and reset to "0" when the determination result is "determination OK". In this case, the alarm output is executed when the determination result is "determination NG" consecutively for the number of times corresponding to the CMOS threshold value.

In the process shown in FIG. 24, the sub CPU 102 generates (outputs) information (an example of information regarding the validity of the inserted game medium) that alerts or warns the use of an illegal medal by outputting an alarm. However, instead of or in addition to this, predetermined display information (information for calling attention or warning the use of an illegal medal) may be generated (output) by the light emitting display device 11. Alternatively, in place of or in addition to the alarm output, the sub CPU 102 sets the error content in the error information history area provided in the sub RAM 723 with information indicating that fact (information to alert or warn the use of an illegal medal). , The current date and time may be stored as the occurrence date and time.

[CMOS threshold setting process]
FIG. 26 is a flowchart showing an example of the CMOS threshold setting process executed by the sub CPU 722. FIG. 27 is a diagram showing the relationship between the position of the volume switch 87 and the CMOS threshold value. FIG. 28 is a diagram showing the relationship between the position of the volume switch 87 and the stage of the volume.

Here, first, FIG. 27 and FIG. 28 will be described, and then FIG. 26 will be described.

As shown in FIG. 27, in the present embodiment, the position of the volume switch 87 and the CMOS threshold value are associated with each other. In the present embodiment, "5", "10", and "15" as CMOS threshold values are set at the three positions of the volume switch 87, that is, the first conduction position, the second conduction position, and the third conduction position, respectively. It is associated. That is, "5" is associated with the first conduction position, "10" is associated with the second conduction position, and "15" is associated with the third conduction position. Information indicating the correspondence as shown in FIG. 27 is stored in the ROM cartridge substrate 86.

As shown in FIG. 28, in the present embodiment, the three positions of the volume switch 87, that is, the first conduction position, the second conduction position, and the third conduction position, are "LOW" and "MIDDLE" as the volume stage. "And" HIGH "are associated with each other. That is, "LOW" is associated with the first conduction position, "MIDDLE" is associated with the second conduction position, and "HIGH" is associated with the third conduction position. Information representing the correspondence as shown in FIG. 28 is stored in the ROM cartridge substrate 86.

In this embodiment, as shown in FIGS. 27 and 28, “LOW”, “Threshold”, and “HIGH” as the volume stage are the three positions (first conduction position, first conduction position, first conduction position) of the volume switch 87. It corresponds to each of "5", "10", and "15" as CMOS threshold values through the two conduction positions and the third conduction position), but is not limited to this. For example, "15", "10", and "5" as CMOS threshold values may be associated with the first conduction position, the second conduction position, and the third conduction position, respectively.

With reference to FIG. 26, a CMOS threshold setting process executed by the sub CPU 722 at a fixed cycle (for example, every 10 msec) will be described.

In the CMOS threshold setting process, first, in step S260, the sub CPU 722 determines whether or not the setting switch 56 is in the ON state. That is, the sub CPU 722 determines whether or not the setting switch 56 is turned on by the setting key. If the determination result is "YES", the process proceeds to step S262, and if the determination result is "NO", the process ends as it is.

In step S262, the sub CPU 722 stores the current position of the volume switch 87 (any one of the first conduction position to the third conduction position) in the sub RAM 723. The position of the volume switch 87 saved here is the position when the setting switch 56 is turned from the off state to the on state, in other words, the position when the setting switch 56 is in the most recent off state. be.

In step S264, the sub CPU 722 determines whether or not the position of the volume switch 87 has changed from the previously acquired position. For example, if the position of the volume switch 87 acquired last time was the first conduction position, but the current position of the volume switch 87 is the second conduction position, the sub CPU 722 acquired the position of the volume switch 87 last time. It is determined that the position has changed. In step S264, the sub CPU 722 proceeds to step S266 if the determination result is "YES", and proceeds to step S268 if the determination result is "NO".

In step S266, the sub CPU 722 selects a CMOS threshold value corresponding to the current position of the volume switch 87. That is, the sub CPU 722 selects the CMOS threshold value corresponding to the current position of the volume switch 87 according to the correspondence shown in FIG. 27. For example, when the current position of the volume switch 87 is the first conduction position, “5” is selected as the CMOS threshold value.

In step S268, the sub CPU 722 determines whether or not the setting switch 56 is in the off state. That is, the sub CPU 722 determines whether or not the setting switch 56 has been switched from the on state to the off state or is in the off state. If the determination result is "YES", the process proceeds to step S270, and if the determination result is "NO", the process returns to step S264. In this case, in order to obtain a change in the position of the new volume switch 87 (change in the position of the volume switch 87 from the previously acquired position) or a change in the setting switch 56 switching from the on state to the off state. Before returning to step S264, a waiting process of waiting for a certain period of time (for example, 10 msec) is performed.

In step S270, the sub CPU 722 stores (overwrites) the CMOS threshold selected in step S266 in the threshold storage area related to the CMOS threshold in the sub RAM 723.

In step S272, the sub CPU 722 determines whether or not the current position of the volume switch 87 is the same as the position of the volume switch 87 stored in step S262. As described above, the position of the volume switch 87 stored in step S262 is the position of the volume switch 87 before the turned-on setting switch 56 is turned on (or at the time when the turned-on setting switch 56 is turned on). If the determination result is "NO", the process proceeds to step S274, and if the determination result is "YES", the process ends as it is.

In step S274, the sub CPU 722 sets the volume stage (one of the three stages of “LOW”, “MIDDLE”, and “HIGH”) based on the position of the volume switch 87 stored in step S262. .. That is, the sub CPU 722 sets the volume stage according to the position of the volume switch 87 stored in step S262 according to the correspondence shown in FIG. 28. For example, when the position of the volume switch 87 stored in step S262 is the first conduction position, “LOW” is selected as the volume stage.

According to the CMOS threshold value setting process shown in FIG. 26, if the setting switch 56 is in the ON state, the CMOS threshold value can be changed based on the change in the position of the volume switch 87. When the setting switch 56 is turned on, the game processing of the pachi-slot machine 1, including various effects, is stopped. After that, when the setting switch 56 is in the off state, a new CMOS threshold value is stored in the threshold value storage area related to the CMOS threshold value, so that the effective state (the state capable of functioning in S154 of FIG. 24) is obtained.

Although not shown in FIG. 26, when the sub CPU 722 executes and ends step S274 of the CMOS threshold setting process, the set volume stage and the position of the volume switch 87 do not match. That (that does not match the relationship shown in FIG. 28) may be notified to the outside after a certain period of time via the speakers 20L and 20R.

As a modification of FIG. 26, in step S266, the sub CPU 722 may further output the selected CMOS threshold value to the outside. For example, the sub CPU 722 may output a voice representing the selected CMOS threshold value via the speakers 20L and 20R. For example, if a CMOS threshold with a value of "5" is selected, "CMOS threshold will be changed to 5", "threshold setting will be changed", or "HIGH" (strict against fraudulent medals as threshold). It means that it becomes) ”may be output. Further, the output of the selected CMOS threshold value to the outside may be realized by the display by the light emitting display device 11 in place of or in addition to the voice. In this case, the user (for example, the person in charge of the store who can use the setting key) can easily determine whether or not the operation for setting the desired CMOS threshold value has been performed in the desired manner, which is convenient. Will be.

Further, as a modification of FIG. 26, in step S270, the sub CPU 722 may further output the CMOS threshold value stored in the threshold value storage area related to the CMOS threshold value to the outside. For example, the sub CPU 722 may output a voice representing the selected CMOS threshold value via the speakers 20L and 20R. For example, if a CMOS threshold with the value "5" is stored, "CMOS threshold has been changed to 5", "threshold setting has been changed", or "HIGH has been set". Audio may be output. Further, the output of the selected CMOS threshold value to the outside may be realized by the display by the light emitting display device 11 in place of or in addition to the voice. In this case, the user can easily determine whether or not the operation for setting the desired CMOS threshold value has been completed, which is convenient.

Further, in FIG. 26, the sub CPU 722 stores the CMOS threshold value selected in step S266 in the threshold value storage area related to the CMOS threshold value when the setting switch 56 changes from the on state to the off state, but this is limited to this. I can't. For example, each time the sub CPU 722 determines in step S264 that the position of the volume switch 87 has changed from the previously acquired position, the sub CPU 722 sets the CMOS threshold value corresponding to the current position of the volume switch 87 in the threshold storage area related to the CMOS threshold. It may be stored (overwritten). Also in this case, when the setting switch 56 finally changes from the on state to the off state, the CMOS threshold value stored in the threshold value storage area related to the CMOS threshold value at that time functions in the effective state (S154 in FIG. 24). Since it is in a state where it can be done), a substantially equivalent configuration can be realized.

Further, in the present embodiment, the CMOS threshold value is set in three stages using the volume switch 87, but for example, a switch such as the setting switch 56 may be used, or the volume switch 87 may be used. You may also use a switch with many contacts. Specifically, when a switch having only an on state and an off state is used, the CMOS threshold value may be set to "5" if the switch is on, and the CMOS threshold value may be set to "15" if the switch is off state. When a switch having more contacts than the volume switch 87 is used, the value may be set to the same magnification with respect to the position of the contact, and an extreme value (for example, "50") may be set only at the position of a specific contact. , "100, etc.) may be set.

[Volume setting process]
The volume setting process will be described with reference to FIG. 29. FIG. 29 is a flowchart showing an example of the volume setting process. FIG. 29 is preferably executed in combination with the CMOS threshold setting process of FIG.

The volume setting process is also executed by the sub CPU 722 at a constant cycle (for example, every 10 msec) like the CMOS threshold setting process described above.

In the volume setting process, first, in step S280, the sub CPU 722 determines whether or not the setting switch 56 is in the ON state. When the determination result is "NO" (that is, when the setting switch 56 is in the off state), the process proceeds to step S282, and when the determination result is "YES", the process ends as it is.

In step S282, the sub CPU 722 determines whether or not the position of the current volume switch 87 has changed from the position of the volume switch 87 acquired last time. The position of the volume switch 87 is acquired for each processing cycle regardless of the state of the setting switch 56. If the determination result is "YES", the process proceeds to step S284, and if the determination result is "NO", the process ends as it is.

In step S284, the sub CPU 722 sets the volume stage (one of the three stages of "LOW", "MIDDLE", and "HIGH") based on the position of the current volume switch 87. That is, the sub CPU 722 sets the volume stage according to the position of the current volume switch 87 according to the correspondence shown in FIG. 28. For example, when the current position of the volume switch 87 is the second conduction position, “MIDDLE” is selected as the volume stage.

According to the process shown in FIG. 29, only when the setting switch 56 is in the off state, the stage of the set volume is changed in response to the change in the position of the volume switch 87.

[Effects of CMOS threshold setting process and volume setting process]
Next, with reference to FIG. 30, the effects of the above-mentioned CMOS threshold value setting process and volume setting process will be described.

FIG. 30 is a timing chart showing an example of changes in various parameters with respect to the CMOS threshold value setting process and the volume setting process. In FIG. 30, in order from the top, the state of the setting key (on / off state of the setting switch 56), the state of the volume switch 87 (on / off state), the state of the CMOS threshold value, and the state of the volume stage. Is shown in chronological order.

In FIG. 30, as an example, before the time point t0 when the setting switch 56 is switched from the off state to the on state, the setting switch 56 is in the off state, the volume switch 87 is in the first conduction position, and the CMOS threshold value is set. Is "5" and the volume stage is "LOW".

At the time point t0, the setting switch 56 is switched from the off state to the on state. When the setting switch 56 is turned on, the game processing of the pachi-slot machine 1, including various effects, is stopped. That is, when the setting switch 56 is turned on, the processes from step S262 to step S268 in FIG. 26 are executed until the setting switch 56 is turned off.

Then, at time point t1, the volume switch 87 is changed from the first conduction position to the second conduction position. At this point t1, as described with reference to FIG. 26, the CMOS threshold value “10” corresponding to the second conduction position is only selected and is not stored in the threshold value storage area related to the CMOS threshold value (“10” in FIG. 30). See "Unconfirmed state").

Then, at the time point t2, the setting switch 56 is switched from the on state to the off state. Along with this, the selected CMOS threshold value "10" corresponding to the second conduction position is stored in the threshold value storage area related to the CMOS threshold value. That is, the CMOS threshold is set to "10". At this time, although the position of the volume switch 87 is the second conduction position, the volume stage remains “LOW” due to step S274 in FIG.

In FIG. 30, the volume switch 87 is changed from the second conduction position to the first conduction position at the time point t3 after the time point t2. In this case, the determination result is "YES" in step S282 of FIG. 29, but since the volume stage is originally "LOW", it does not change.

By the way, the smaller the CMOS threshold value, the easier it is for the alarm output (S155 in FIG. 24) to be executed. That is, the smaller the CMOS threshold value, the higher the detection sensitivity of fraudulent medals (the determination conditions become stricter). Therefore, the CMOS threshold can be set to a fixed value according to the average needs.

However, medals differ from store to store, and even in the same store, the state of the engraving on the surface of the medal varies from time to time due to deterioration and dirt due to wear. Therefore, in the pachi-slot machine 1 that determines a medal using a CMOS image sensor 232 (see FIG. 16) as in the present embodiment, the reliability of determining whether or not the medal is a regular medal is determined according to the state of the medal to be used. Gender is also different. From this point, it is useful to set an appropriate CMOS threshold value according to each store and the degree of aging, and therefore, it is convenient if the CMOS threshold value can be changed.

In this respect, for example, unlike the present embodiment, in the pachislot equipped with the liquid crystal display device, a threshold value setting menu is provided in the menu that can be selected on the hall menu screen displayed on the liquid crystal display device, and the menu is selected. If so, the CMOS threshold can be changed to any value. However, it is difficult to provide a new man-machine interface in a pachi-slot machine that is not equipped with a liquid crystal display device as in the present embodiment. For this reason, it is difficult to establish a medal selector equipped with a CMOS image sensor in a pachislot machine that is not equipped with a liquid crystal display device.

On the other hand, in the present embodiment, even in the pachi-slot machine 1 not equipped with the liquid crystal display device, it is possible to provide the medal selector 201 equipped with the CMOS image sensor 232 as described above. That is, according to the present embodiment, the CMOS threshold value can be set (changed) by using the existing man-machine interface such as the setting switch 56 and the volume switch 87 instead of the liquid crystal display device. A pachislot 1 equipped with a medal selector 201 equipped with a sensor 232 can be established.

Here, the volume switch 87 has a function of setting a sound volume stage according to a position as an original function. Therefore, in a configuration in which the CMOS threshold value is simply set according to the position of the volume switch 87, the volume stage depends on the CMOS threshold value. That is, when one of the CMOS threshold and volume stages is changed, the other is also changed.

In this respect, in the present embodiment, as described above, since the volume switch 87 is used in cooperation with the setting switch 56, the above-mentioned interlocking can be reduced (or avoided). That is, in the present embodiment, the change of the position of the volume switch 87 for adjusting the volume stage is enabled only when the setting switch 56 is in the off state, and the change of the volume switch 87 for changing the CMOS threshold value is performed. The change of position is effective only when the setting switch 56 is in the ON state. In this way, in the present embodiment, by utilizing the on / off state of the setting switch 56, the volume switch 87 has a new function (that is, a CMOS threshold setting function) without interfering with the original function of the volume switch 87. ) Can be given. That is, it is possible to minimize the influence on the existing function when the existing function is also used.

In particular, in the present embodiment, as described above, in the CMOS threshold setting process, step S262, step S272, and step S274 of FIG. 26 are included. As a result, the position of the volume switch 87 changed by the user for changing the CMOS threshold value while the setting switch 56 is on is not returned to the original position after the setting switch 56 is returned to the off state. However, the volume stage is not (unintentionally) changed before and after the change of the CMOS threshold. That is, even if the position of the volume switch 87 is forgotten to return to the original position (the position before the setting switch 56 is turned on), the volume stage is not changed, so that the convenience of the user is improved. However, in the modified example, in the CMOS threshold setting process, step S262, step S272, and step S274 in FIG. 26 may be omitted (see FIGS. 31 and 32 below).

Further, in the present embodiment, the change of the position of the volume switch 87 for changing the CMOS threshold value is enabled only when the setting switch 56 is on, so that the CMOS threshold value is changed only when the game processing is stopped. Can be operated for. This enables an operation for changing the CMOS threshold value without interfering with the game processing.

[Modification example of CMOS threshold setting process and volume setting process]
FIG. 31 is a flowchart showing another example (modification example) of the CMOS threshold value setting process.

In step S300, the sub CPU 722 determines whether or not the setting switch 56 has transitioned from the off state to the on state. If the determination result is "YES", the process proceeds to step S302, and if the determination result is "NO", the process ends as it is.

In step S302, the sub CPU 722 acquires the current position of the volume switch 87.

In step S304, the sub CPU 722 sets a CMOS threshold value corresponding to the current position of the volume switch 87. That is, the sub CPU 722 stores (overwrites) the CMOS threshold value corresponding to the current position of the volume switch 87 in the threshold value storage area related to the CMOS threshold value in the sub RAM 723 according to the correspondence relationship shown in FIG. 27. For example, when the current position is the first conduction position, "5" is stored (overwritten) in the threshold storage area related to the CMOS threshold in the sub RAM 723 as the CMOS threshold.

Here, in FIG. 26 described above, the sub CPU 722 monitors whether or not the position of the volume switch 87 has changed from the previously acquired position in step S264 while the setting switch 56 is on, and in step S264. Each time it is determined that the position of the volume switch 87 has changed from the previously acquired position, the CMOS threshold value corresponding to the current position of the volume switch 87 is selected. On the other hand, in this modification, as shown in FIG. 31, the sub CPU 722 does not execute any processing while the setting switch 56 is in the on state, and the setting switch 56 changes from the on state to the off state. When switching, the CMOS threshold value corresponding to the position of the volume switch 87 at that time (whether or not the setting switch 56 has changed while the setting switch 56 is in the ON state) is set in the threshold value storage area related to the CMOS threshold value. Store (overwrite). Even with such a modification, the CMOS threshold value can be appropriately changed by using the volume switch 87 and the setting switch 56.

FIG. 32 is a flowchart showing another example (modification example) of the volume setting process. FIG. 32 is preferably executed in combination with the CMOS threshold setting process of FIG.

In step S310, the sub CPU 722 determines whether or not the setting switch 56 is in the ON state. If the determination result is "NO", the process proceeds to step S312, and if the determination result is "YES", the process ends as it is.

In step S312, the sub CPU 722 acquires the current position of the volume switch 87.

In step S314, the sub CPU 722 performs the volume stage (one of the three stages of "LOW", "MIDDLE", and "HIGH") corresponding to the current position of the volume switch 87. Set.

Here, in FIG. 29 described above, when the position of the current volume switch 87 changes from the position of the volume switch 87 acquired last time when the setting switch 56 is in the off state, the sub CPU 722 is changed. The volume stage corresponding to the position of the volume switch 87 is set. On the other hand, in this modification, as shown in FIG. 32, the sub CPU 722 sets the volume stage corresponding to the current position of the volume switch 87 when the setting switch 56 is in the off state. In this case, if the position of the volume switch 87 is changed while the setting switch 56 is on, the change is reflected in the volume stage in the subsequent off state of the setting switch 56, but the user. However, if the position of the volume switch 87 is changed to a desired position, the volume stage can be set to the desired stage. It should be noted that such a modification does not completely eliminate the interlocking (the interlocking that when one of the CMOS threshold and volume stages is changed, the other is also changed). Although it is more disadvantageous than the combination of the CMOS threshold value setting process and the volume setting process shown in FIG. 29, the relationship between the position of the volume switch 87 and the set volume stage always has the correspondence relationship shown in FIG. 28. In terms of matching, it is an aspect that is easy for the user to understand.

[Other expandability of gaming machines according to the present embodiment]
In the pachi-slot machine 1 of the present embodiment, the player's medal insertion operation (that is, the operation of inserting a hand-held medal into the medal insertion slot 13 or the credited medal is inserted into the MAX bet button 14 or the 1-bet button 15). If the game is started by (operation of inserting) and the medal is paid out when the game is finished, the hopper device 51 is driven and the medal is paid out from the medal payout outlet 18, or the credit is given. The form to be used has been described, but the present invention is not limited to this.

For example, the present invention is applied to all forms in which a game medium necessary for a game is input by a player, a game is played based on the game, and a privilege is given (for example, a medal is paid out) based on the result of the game. be able to. That is, not only the game medium is thrown in (hanged) by the physical movement of the player and the game medium is paid out, but also the main control circuit 91 (main control board 71) itself is the game medium owned by the player. It may be possible to play a game without a medal by electromagnetically managing the above. Further, the game medium owned by the player may be electromagnetically managed by a game medium management device mounted (connected) to the main control circuit 91 (main control board 71) and managing the game medium. ..

In this case, the game media management device has a ROM and an RWM (or RAM) and is provided in the game machine, and is bidirectionally communicated with an external game medium handling device (not shown) via a predetermined interface. It is connected so that it can be connected, and a prize is won for a role related to the operation of lending the game medium (that is, the operation of providing the game medium necessary for the player to perform the operation of inserting the game medium) or the payout of the game medium (that is, the operation of providing the game medium). When the winning combination is established), a game medium payout operation (that is, an action of acquiring a game medium necessary for paying out the game medium to the player) or a game medium to be used for the game is used. It suffices that the operation of recording electromagnetically can be performed. Further, the game media management device not only manages the actual number of game media, but also, for example, displays the number of game media possessed on the front surface of the pachislot 1 based on the management result of the number of game media. A number display device (not shown) may be provided to manage the number of game media displayed on the possessed game medium number display device. That is, the game media management device may be capable of recording and displaying the total number of game media that the player can use for the game by an electromagnetic method.

Further, in this case, the game media management device has a performance that allows the player to freely transmit a signal indicating the number of recorded game media to an external game medium handling device, and also has a game. In addition to the case where a person directly operates the game medium, the number of recorded game media cannot be reduced, and an external connection terminal plate (not shown) is provided between the device and an external game medium handling device. It is desirable that the player has the ability to transmit a signal indicating the number of recorded game media only through the external connection terminal plate.

In addition to the above, the game machine is provided with a lending operation means, a return (clearing) operation means, and an external connection terminal board that can be operated by the player. (For example, IC card) insertion slot, non-contact communication antenna for depositing electronic money from mobile terminals, other operation means such as lending operation means, return operation means, external connection terminal board on the game medium handling device side It may be provided (neither is shown).

As a flow of the game at that time, for example, the player deposits valuable value into the game medium handling device by any method, and subtracts a predetermined number of valuable values based on the operation of any of the above lending operation means. Then, the number of game media corresponding to the valuable value subtracted from the game media handling device to the game media management device is increased. Then, the player plays a game, and if a game medium is required, the above operation is repeated. After that, as a result of the game, a predetermined number of game media are acquired, and when the game is finished, the number of game media is transmitted from the game media management device to the game medium handling device by operating one of the return operation means, and the game is played. The medium handling device discharges a recording medium recording the number of game media. The game medium management device clears the number of game media stored by self-confidence when the number of game media is transmitted. The player takes the discharged recording medium to a prize counter or the like for exchanging prizes, or moves the game table to play a game based on the game medium recorded on another table.

In the above example, all the game media are transmitted to the game medium handling device, but only the number of game media desired by the player is transmitted on the game machine or the game medium handling device side, and the game medium possessed by the player is transmitted. It may be divided and processed. Further, the recording medium is not limited to being discharged, and cash or a cash equivalent may be discharged, or may be stored in a mobile terminal or the like. Further, the game medium handling device may be capable of inserting a member recording medium of the game hall, storing it in the member recording medium, and making it possible to replay the game at a later date.

Further, in the game machine or the game medium handling device, it is possible to execute a lock operation for locking the game medium or valuable data communication to the game medium handling device or the game medium management device by operating a predetermined operating means (not shown). May be good. In that case, information such as a one-time password that only the player can know may be set, or the player may be stored by an imaging means provided in the game machine or the game medium handling device.

As described above, the game medium management device may be capable of playing games only without a medal, or the game medium is inserted (hanged) by the physical movement of the player, and the game medium is played. It may be a form in which the game is paid out, a form in which the game is possible without a medal, or a form in which the game is possible in both forms. In this case, the game medium management device may adopt a method of directly controlling the above-mentioned medal selector 201 and the hopper device 51, and these are controlled by the main control circuit 91 (main control board 71). , Based on the transmission of the control result, a method is adopted that enables control to record and display the total number of game media that the player can use for the game by an electromagnetic method. You can also do it.

Further, although the case where the game medium management device is applied to the pachi-slot machine 1 is described above, the above-mentioned pachinko machine or the enclosed game machine using the game ball is also provided with the game medium management device, and the player can use the game medium management device. It is also possible to manage the game medium.

As described above, by providing the above-mentioned game medium management device, it is possible to reduce the number of medal selector 201, hopper device 51, etc. inside the game machine as compared with the case where the game medium is physically used for the game. Not only can the cost and manufacturing cost of the machine be reduced, but also the player can be prevented from coming into direct contact with the gaming medium, the gaming environment can be improved, noise can be reduced, and the number of devices can be reduced. It also reduces the power consumption of the machine. In addition, it is possible to prevent fraudulent acts through the game medium and the slot and payout port of the game medium. That is, it is possible to provide a gaming machine that can improve various environments surrounding the gaming machine.

It is an object of the present invention to provide a gaming machine capable of changing the threshold value used for determining the validity of the inserted gaming medium.

In order to solve the second problem, the present invention provides the 2-1 to 2-3 gaming machines having the following configurations.

A control means (for example, a sub CPU 722) connected to the medium discriminating means is provided.
The control means is
An input medium determination means (for example, S155 in FIG. 24) that determines the validity of the input game medium based on the determination result of the medium determination means and a threshold value (for example, the CMOS threshold in FIG. 27).
The contacts of the second contact means change from a conductive state to a non-conducting state based on a predetermined correspondence relationship (for example, FIG. 27) between the contact state of the first contact means and the threshold value. In this case, a threshold value setting means (for example, S270 in FIG. 26 and S304 in FIG. 31) for setting the threshold value to a value corresponding to the contact state of the first contact means.

The threshold used for determination can be changed. Further, since the conditions under which the threshold value setting means (for example, S270 in FIG. 26 and S304 in FIG. 31) function are limited, the functions of the volume setting means (for example, S284 in FIG. 29 and S314 in FIG. 32) are not substantially impaired. , The influence on the original function of the first contact means can be reduced.

In the volume setting means, the state of the contact of the first contact means is different from the state of the contact stored in the multi-contact state storage means when the contact of the second contact means changes from the conductive state to the non-conducting state. In some cases (for example, “NO” in S272 of FIG. 26), the volume is set at a stage corresponding to the state of the contacts stored in the multi-contact state storage means (for example, S274 of FIG. 26). ..

In the 2-1 or 2-2 gaming machine (1), the control means is
When the contact of the second contact means is in a non-conducting state, when the state of the contact of the first contact means changes, the volume is set at a stage corresponding to the state of the contact after the change (for example). S284 in FIG. 29, S314 in FIG. 32),
When the contacts of the second contact means are in a conductive state, the volume setting is not changed even if the state of the contacts of the first contact means changes (for example, "YES" in S280 of FIG. 29, FIG. 32. It is characterized by "YES") in S310 of.
