[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for starting a pachinko game under appropriate game conditions at the start of business after a power failure recovery.
[0002]
[Prior art]
Various electrical devices (for example, a prize ball device, a symbol display device, etc.) are assembled in the pachinko machine, and control is performed based on signals (control information) emitted from various sensors. The control information is temporarily stored in a storage device such as a memory provided in the electrical equipment, and the control information stored in the memory is appropriately read out by the control equipment, and the electrical equipment is controlled based on the read control information. It has a configuration.
Here, the control information stored in the memory includes information advantageous to the player (for example, prize ball release information, probability variation information, etc.). This will have a detrimental effect for a player who wants to continue playing pachinko. For this reason, there is a request to retain control information stored in the memory at the time of a power failure and to continue the pachinko game from the state before the power failure at the start of business after the recovery from the power failure.
On the other hand, if the control information in the memory is memorized at the time of a power failure and the pachinko game is started from the state before the power failure after recovery from the power failure, the game before the power failure will occur, such as when a player returns due to a power failure. Even when it is not necessary to continue the state, the game state before the power failure continues.
For this reason, conventionally, a pachinko machine that solves the above-described problem by providing a continuation switch and a clear switch for selecting whether to continue or clear the gaming state before the power failure when the power is turned on after the power failure is known. (Japanese Patent Publication No. 4-50035).
[0003]
[Problems to be solved by the invention]
In the pachinko machine described in the above publication, once the continuation switch is pressed, the continuation state is maintained unless the clear switch is pressed. Similarly, once the clear switch is pressed, the continuation state is cleared unless the continuation switch is pressed. Was maintained. For this reason, for example, when the clear switch is pressed and the pachinko machine is set to the clear state, and the state before the power failure must be continued, the state before the power failure is maintained by forgetting to press the continuation switch. The situation that it was not possible occurred. As described above, in the pachinko machine described in the above publication, since either the continuation switch or the clear switch must be selected at the time of recovery from the power failure, the stored contents of the storage device are mistakenly erased due to forgetting to press or the like. There was an inconvenience.
[0004]
The present invention has been made in view of these points, and realizes a pachinko machine that can prevent the stored contents of the storage device from being accidentally erased.
[0005]

The prize ball control unit includes a RAM that stores control information for controlling the prize ball device, and a CPU that controls the prize ball device based on the control information stored in the RAM. Control information stored in the RAMs of the main control unit and the prize ball control unit at the time of a power failure is held. A power switch for turning on / off the power input to the pachinko machine, a game condition initialization switch for initializing game conditions, and an erroneous operation prevention switch for preventing erroneous operation of the game condition initialization switch are provided. A power switch, a game condition initialization switch, and an erroneous operation prevention switch are provided in the same power supply device. The game condition initialization switch and the erroneous operation prevention switch are contact opening type switches that are always off when not being operated, and are connected to the CPUs of the main control unit and the prize ball control unit. Each CPU of the main control unit and prize ball control unit (1) determines whether or not the game condition initialization switch and the erroneous operation prevention switch are turned on only when the power is turned on when the power switch is turned on. (2) When both the game condition initialization switch and the erroneous operation prevention switch are turned on, the control information held in the respective RAMs is cleared, while both the game condition initialization switch and the erroneous operation prevention switch are turned on. If not, do not clear control information stored in each RAM It is configured as follows.
In the above pachinko machine, the game condition initialization switch And misoperation prevention switch Is always in an unoperated state Turn off Since it is configured as such, the game condition initialization switch And misoperation prevention switch Unless you operate RAM The stored content stored in is not cleared. Therefore, with the above pachinko machine RAM Can be prevented from being accidentally cleared.
[0006]
The gaming condition initialization switch is preferably provided on the back side of the pachinko machine. By providing it on the back side of the pachinko machine, it is possible to prevent the player from operating carelessly and clearing the stored contents stored in the storage means.

The first type start port 30 has a start port sensor (not shown), and detects a pachinko ball winning the first type start port 30 by the start port sensor. The special winning opening 34 has an open / close lid 36, and the open / close lid 36 is opened and closed by a solenoid (not shown) under specific conditions. The period during which the open / close lid 36 is opened ends, for example, when a predetermined number (generally 10) of pachinko balls enter the big prize opening 34 or until 30 seconds have passed since opening. To do.
The symbol display device 14 includes a symbol indicator 22 that variably displays a special symbol. The symbol indicator 22 displays a special symbol under a specific condition (for example, winning a pachinko ball to the first type starting port 30). Display fluctuations. The special symbol variably displayed on the symbol display 22 is for allowing the player to recognize the transition to a so-called special game state (a state in which the big prize opening 34 is opened) by the display mode when the variation is stopped.
A pachinko ball that has won a prize opening such as the first type starting opening 30 and the grand prize opening 34 is detected by a winning ball sensor (not shown) provided on the back side of the game board surface 12, and the back side of the game board surface 12 is also the same. Pachinko balls are paid out from a prize ball device (not shown) assembled in the. The operation of the prize ball device is controlled by a prize ball control unit described later.
[0010]
In addition to the game board surface 12 described above, the pachinko machine 10 is provided with a blood drop 40 for temporarily storing pachinko balls including prize balls and rental balls, an ashtray 42 for storing cigarette butts, and the like. Since the structure and the like of these devices are the same as those of a known pachinko machine, detailed description thereof is omitted.
[0011]
Next, the structure of the electrical system of the pachinko machine 10 shown in FIG. 1 will be described with reference to FIGS. As shown in FIG. 3, the electrical system of the pachinko machine 10 according to the present embodiment is connected to the power supply device 100 and the power supply device 100, as in the conventional pachinko machine, and the pachinko machine is powered by the power supplied from the power supply device 100. A control device (hereinafter referred to as a main control unit) 200 that controls the entire machine, a prize ball control unit 300 that controls the prize ball device 40 based on control information (command data) transmitted from the main control unit 200, and a main control unit A winning ball sensor 50, a start opening sensor 32, a symbol display 22, a solenoid 35 (which opens and closes the open flat cover 36 of the large winning opening 34), etc., electrically connected to 200. The power supply device 100, the main control unit 200, and the prize ball control unit 300 are all provided on the back surface of the pachinko machine 10, as shown in FIG.
The winning ball sensor 50, the start port sensor 32, the symbol display 22, the solenoid 35, and the like may be anything provided in a normal pachinko machine, and do not particularly characterize the present invention. Detailed description is omitted.
[0012]
Hereinafter, the configuration of the main control unit 200, the prize ball control unit 300, and the power supply apparatus 100 will be described.
The main control unit 200 includes a CPU (processor) 202, a storage device such as a ROM 202a and a RAM 202b connected to the CPU 202, an input processing circuit 204, a communication control circuit 206, and the like. The CPU 202 controls the pachinko machine 10 according to a control program stored in the ROM 202a. For example, when a winning detection signal is received from the start port sensor 32, a lottery change instruction is given to the symbol display 22, and the large winning port 34 is opened (ie, the opening control of the open / close lid 36 by the solenoid 35) is performed in the case of a big hit. The control program stored in the ROM 202a includes a program for realizing a power failure process and a clear process, which will be described later.
The RAM 202b indicates that there is a high probability that the winning ball information transmitted from the winning ball sensor 50, the starting port information transmitted from the starting port sensor 32, and the special symbol displayed on the symbol display 22 will be a “hit”. Various data such as probability variation information is stored. In the present embodiment, a constant amount of charge is stored in the current-carrying capacitor, and when power is cut off (during a power failure), a constant current is caused to flow to the RAM 202b by the charge stored in the capacitor, and the RAM 202b The stored content is stored. In addition, as a method of holding the storage contents of the RAM 202b at the time of a power failure or the like, the storage contents stored in the RAM 202b can be held by using a non-volatile flash memory in the RAM 202b in addition to the method described above.
The input processing circuit 204 is a circuit that processes signals transmitted from the winning ball sensor 50, the start port sensor 32, the initialization switch 102, the power failure detection unit 106, and the like so that the CPU 202 can handle them. The output processing circuit 208 is a circuit that outputs a drive signal to the solenoid 35, and the communication control circuit 206 is a circuit for transmitting command data to the symbol display 22, the prize ball control unit 300, and the like.
[0013]
In response to command data (ball payout information) sent from the main control unit 200, the prize ball control unit 300 performs a prize ball payout process for paying out a predetermined number of prize balls from the prize ball device 40. The prize ball controller 300 includes a CPU 302, a ROM 302a, a RAM 302b, a communication control circuit 303, an input processing circuit 304, an output processing circuit 306, and the like.
The CPU 302 performs prize ball payout control and the like of the prize ball device 40 in accordance with a control program stored in the ROM 302a. The control program stored in the RAM 302a includes a program for realizing a power failure process and a clear process, which will be described later, as in the case of the main control unit 200.
The RAM 302b stores various data such as ball payout information and input / output signals. In the RAM 302b of the present embodiment, the stored contents stored in the RAM 302b are retained even during a power failure, etc., using the electric charge stored in the capacitor during energization, like the main control unit 100. Note that the storage contents of the RAM 302b may be retained using a nonvolatile flash memory, as in the case of the main control unit 100.
The communication control circuit 303 is a circuit for receiving data transmitted from the main control unit 200 and the like, and the input processing circuit 304 is for receiving signals output from the initialization switch 102 and the power failure detection unit 104 and the like. Further, the output processing circuit 306 receives the data sent from the CPU 302 and controls the prize ball payout to the prize ball device 40 [drive control of the prize ball motor (typically a stepping motor)]. It is an output circuit which outputs the drive signal for performing.
[0014]
The power supply device 100 includes a voltage transformer 106 that supplies power of a predetermined potential to each electrical device assembled in the pachinko machine 10, a power failure detection unit 104 that detects a power failure, a power switch 108, an initialization switch 102, and the like. Various switches are provided.
As shown in FIG. 3, the voltage transformer 106 supplies electric power of a predetermined potential to the main controller 200 and the prize ball controller 300, while the various electrical devices shown in FIG. 1 (the winning ball sensor 50, the start port sensor). 32, the symbol display 22, the solenoid 35, the prize ball device 40, etc.) is supplied with electric power of a predetermined potential. That is, the voltage transformer 106 rectifies and smoothes the AC input from the AC power supply of the hall by a rectifier circuit, and converts the rectified and smoothed DC power supply to a voltage suitable for each electrical device by using a regulator. To supply. In FIG. 3, the illustration of power supply lines to electrical devices other than the main control unit 200 and the prize ball control unit 300 is omitted.
The power failure detection unit 104 continuously monitors the AC input from the Hall AC power source, and determines that a power failure occurs when the waveform continues to be 0 for a predetermined period. The main control unit 200 and the prize ball control unit 300 Supply power failure signal. The power switch 108 is a switch for operating ON / OFF of the AC input from the Hall AC power supply.
The configuration of the voltage transformer 106, the power failure detection unit 104, the power switch 108, and the like are the same as those conventionally known, and thus detailed description thereof is omitted.
[0015]
The initialization switch 102 is a switch that is operated by a hall clerk at the start of business after a power failure recovery. In this embodiment, the initialization switch 102 is a so-called reed switch that closes the contact when pressed.
This will be specifically described with reference to FIG. As illustrated in FIG. 4B, the initialization switch 102 is configured by a push-type switch disposed on a substrate 120 that constitutes a part of the power supply device 100. The initialization switch 102 is accommodated in a case 110 formed of a plastic material having elasticity. As shown in FIG. 4A, the case 110 is provided with a pressing portion 114 at a position facing the initialization switch 102, and a cutout 112 is provided in three directions around the pressing portion 114. A contact portion 116 extending toward the initialization switch 102 is formed on the inner wall surface of the pressing portion 114 facing the initialization switch 102.
In order to turn on the initialization switch 102 having the above-described configuration, a hall clerk or the like presses the pressing portion 114 toward the substrate 120 side. When the pressing portion 114 is pressed toward the substrate 120 and deformed as shown in FIG. 4C, the contact portion 116 presses the initialization switch 102, and the initialization switch 102 is turned on. In order to set the initialization switch 102 to the OFF state, by stopping the pressing of the pressing portion 114, the contact portion 116 is separated from the initialization switch 102, and the contact of the initialization switch 102 is opened to be in the OFF state.
Note that, as shown in FIG. 4B, the pressing portion 114 is formed as a pitch without protruding from the surface of the casing 110, so that the pressing portion 114 is prevented from being accidentally pressed.
[0016]
The relationship between the initialization switch 102 configured as described above and each control unit (in this embodiment, the main control unit 200 and the prize ball control unit 300) will be described with reference to FIG.
As shown in FIG. 5, the output of the initialization switch 102 is input to each control unit via two buffer ICs (indicated by A and B in the figure). As is clear from the circuit diagram shown in FIG. 5, when the initialization switch 102 is in the OFF state, the output from the initialization switch 102 becomes a high level signal, and a high level signal is sent to the control unit via the two buffer ICs. Entered. On the other hand, when the initialization switch 102 is in the ON state, the output from the initialization switch 102 is a low level signal, and a low level signal is input to the control unit via the two buffer ICs.
[0017]
Next, the operation at the time of a power failure in the pachinko machine 10 configured as described above and the operation at the start of business after the recovery from the power failure will be described. First, the operation during a power failure will be described.
In the pachinko machine 10 of the present embodiment, when the supply of power to the pachinko machine 10 is interrupted, the power failure detection unit 104 of the power supply device 100 first determines whether or not a power failure has occurred. When it is determined that a power failure has occurred (when there is no AC input for a predetermined period), a power failure signal is output to the main control unit 200 and the prize ball control unit 300. When the main control unit 200 receives this power failure signal, the CPU 202 starts power failure processing. That is, by prohibiting access to the RAM 202b, the storage contents (for example, probability variation information) stored in the RAM 202b at that time are held. Similarly, in the prize ball control unit 300, the CPU 302 prohibits access to the RAM 302b, and the storage contents (for example, ball payout information) stored in the RAM 302b are held.
[0018]
Next, the operation of the pachinko machine 10 at the start of business after power failure recovery will be described.
As described above, in the pachinko machine 10 according to the present embodiment, the RMAs 202b and 302b provided in the main control unit 200 and the prize ball control unit 300 retain the stored contents at the time of a power failure. The storage contents stored in these RAMs 202b and 302b need to be retained when the player at the time of a power failure plays a pachinko game with the same pachinko machine after the power failure is restored, as described above. If a player returns during a power outage, there is no need to hold it. In particular, when the business is started with the probability variation information stored in the RAM 202b of the main control unit 100 being stored, the pachinko machine 10 starts in the probability variation state from the beginning, and the other Unfairness occurs among players who play with pachinko machines, and it is also a disadvantage on the hall side. Further, if the business is started with the ball payout information stored in the RAM 302b of the prize ball control unit 300 being stored, the prize ball will be paid out even though no person is sitting at the start of the business. In addition, there is a need for the hall clerk to collect the paid-in pachinko balls.
Therefore, in the pachinko machine 10 according to the present embodiment, in the pachinko machine that wants to clear the stored contents, the power switch 108 is turned OFF during the power failure, and the power switch 108 and the initialization switch 102 are turned on at the start of business after the power failure is restored. The stored contents of the RAMs 202b and 302b are cleared by operating simultaneously. In a pachinko machine whose stored contents are to be cleared, the power switch 108 is turned OFF during a power failure when the power is turned on to the pachinko machine 10 as soon as the power failure is restored (the power switch 108 is turned on). This is because it is difficult to operate the initialization switch 102 simultaneously with the recovery from the power failure (when the power is turned on).
[0019]
Hereinafter, clear processing for clearing the stored contents of the RAMs 202b and 302b will be described in detail with reference to FIGS. In addition, since the procedure of the clear process in the main control part 200 and the prize ball control part 300 is the same, the following description demonstrates the process of the main control part 200 as an example.
First, the flow at the time of power-on in the main control unit 200 will be described with reference to FIG. When the CPU 202 reaches an operable voltage, the main control unit 200 initializes the CPU 202 (S10), and determines whether a clear signal transmitted from the initialization switch 102 is received (S12). If the clear signal has been received, the stored contents stored in the RAM 202b are cleared (S16), and then the process proceeds to the main process (S18). If the clear signal has not been received, it is determined whether or not there is any abnormality in the RAM 202b (S14). If an abnormality has occurred in the RAM 202b, the stored contents of the RAM 202b are cleared (S16), and then the process proceeds to the main process (S18). If an abnormality has not occurred in the RAM 202b, the process proceeds to the main process as it is ( S18).
After the transition to the main process of S18, the process returns to S14 at a predetermined timing to determine whether or not an abnormality has occurred in the RAM 202b. If an abnormality has occurred, the RAM 202b is cleared (S16). If no has occurred, the process returns to the main process. Therefore, in this embodiment, after shifting to the main process of S18, it is not determined whether or not the clear signal of S12 is received. That is, whether or not the clear signal of S12 has been received is determined only when the power is turned on, and is not determined otherwise.
[0020]
In order to specifically describe the processing described above, an example of clearing the stored contents stored in the RAMs 202b and 302b will be described with reference to the timing chart of FIG. In order to clear the stored contents of the RAM, as shown in FIG. 7, the power switch 108 is turned on and at the same time the initialization switch 102 is turned on. When the power switch 108 is turned on, AC power is input from the AC power source to the voltage transformer 106. The voltage transformer 106 converts AC input from the AC power source into a predetermined voltage and starts supplying power to the CPU 202 of the main controller 200 and the CPU 302 of the prize ball controller 300.
When power starts to be supplied to the CPU 202 and the CPU 302 by the voltage transformer 106, the voltage supplied to the CPUs 202 and 302 gradually increases with the passage of time. When the CPU 202 and the CPU 302 reach the operable voltage, the CPU 202 and the CPU 302 first perform initialization processing, and then determine whether or not to clear the stored contents of the RAMs 202b and 302b. Specifically, it is determined whether or not each of the CPUs 202 and 302 has received a clear signal transmitted from the initialization switch 102.
When the initialization switch 102 is operated and the CPUs 202 and 302 receive a clear signal, the CPUs 202 and 302 clear the stored contents of the RAM 202b and RAM 302b, respectively (in the case shown in FIG. 7). Conversely, when the initialization switch 102 is not operated and the CPUs 202 and 302 do not receive a clear signal, the stored contents of the RAM 202b and RAM 302b are retained.
[0021]
As described above in detail, in the pachinko machine according to the present embodiment, a clear signal is transmitted only when the initialization switch 102 is operated, and no clear signal is transmitted when the initialization switch 102 is not operated. Therefore, the contents stored in the RAMs 202b and 302b are not cleared unless the initialization switch 102 is operated. For this reason, unlike the conventional pachinko machine, the memory content is not accidentally cleared by forgetting to press the continuation switch.
In the pachinko machine according to the present embodiment, whether or not the clear signal transmitted from the initialization switch 102 is received only once after the CPU control power supply reaches the CPU operable voltage after the power is turned on. Is going to judge. That is, the stored contents of the RAMs 202b and 302b are cleared only when the power switch 108 and the initialization switch 102 are operated almost simultaneously. Therefore, even if the initialization switch 102 is accidentally pressed during energization or the like, the main control unit 200 and the prize ball control unit 300 do not clear the stored contents of the RAMs 202b and 302b. That is, in the pachinko machine of the present embodiment, means for preventing erroneous operation of the initialization switch 102 is configured by software processing (a program for executing clear processing) of the CPUs 202 and 302.
Further, in the pachinko machine 10 according to the present embodiment, since the power supply device 100 is provided with the power switch 108 and the initialization switch 102 (see FIG. 2), both the power switch 108 and the initialization switch 102 are operated simultaneously. It becomes easy.
Further, since the power supply device 100 is provided on the back surface of the pachinko machine 10 (see FIG. 2), the power switch 108 and the initialization switch 102 can be prevented from being erroneously operated by the player.
[0022]
In the above-described embodiment, the CPU control power supply requires a predetermined time from when the power switch 108 is turned ON (when power is turned on) until the CPU operable voltage is reached. Therefore, depending on how the initialization switch 102 is pressed (such as when the finger is released immediately after the switch is pressed), the initialization switch 102 may be turned off before the CPU reaches the operable voltage. For this reason, in the above-described embodiment, it is preferable to provide means (for example, a latch circuit) for holding the clear signal transmitted from the initialization switch 102 for a predetermined time. As a result, the clear signal can be reliably transmitted to the main control unit 200 / prize ball control unit 300.
[0023]
[Other form 1]
A pachinko machine according to another embodiment of the present invention will be described with reference to FIGS. Also in the embodiment shown in FIG. 8, as in the above-described embodiment, the RAM 202b of the main control unit 100 and the RAM 302b of the prize ball control unit 300 are stored based on the operation of the initialization switch 102 provided in the power supply apparatus 100. The point of clearing the contents is the same. However, in the embodiment described below, only when the power supply device 100 is further provided with the erroneous operation prevention switch 103 and the three switches of the power switch 108, the initialization switch 102, and the erroneous operation prevention switch 103 are operated simultaneously. The memory contents of the RAMs 202b and 302b are different. Hereinafter, the difference will be mainly described.
[0024]
In the embodiment shown in FIG. 8, the power supply device 100 is provided with an erroneous operation prevention switch 103 in addition to the initialization switch 102. Similar to the initialization switch 102, the erroneous operation prevention switch 103 is constituted by a reed switch. The erroneous operation prevention switch 103 outputs a confirmation signal to the main control unit 200 and the prize ball control unit 300 only when operated (pressed), and when not operated, the confirmation signal is sent to the main control unit 200 and the prize ball control unit. 300 is not output.
[0025]
Operations of the main control unit 200 and the prize ball control unit 300 in the pachinko machine provided with such an erroneous operation prevention switch 103 when the power is turned on will be described with reference to FIGS. Here, FIG. 9 shows a processing flow in each control unit, and FIG. 10 shows a timing chart at that time. Here, since the flow in the main controller 200 and the prize ball controller 300 is the same, only the flow of the main controller 200 will be described in the following description.
First, the main control unit 200 initializes the CPU 202 (S20), and then determines whether a clear signal transmitted from the initialization switch 102 has been received (S22). If the clear signal has not been received, it is determined whether or not there is any abnormality in the RAM 202b (S26). If an abnormality has occurred in the RAM 202b, the stored contents of the RAM 202b are cleared (S28), and then the process proceeds to the main process (S30). If no abnormality has occurred in the RAM 202b, the process proceeds to the main process as it is ( S30).
If it is determined in step S22 that a clear signal has been received, it is determined whether a confirmation signal transmitted from the erroneous operation prevention switch 103 has been received (S24). If the confirmation signal has been received, the stored contents of the RAM 202b are cleared (S28). If the confirmation signal has not been received, the process proceeds to S26, and it is determined whether or not there is an abnormality in the RAM 202b (S26). . If an abnormality has occurred in the RAM 202b, the stored contents of the RAM 202b are cleared (S28), and then the process proceeds to the main process (S30). If no abnormality has occurred in the RAM 202b, the process proceeds to the main process as it is ( S30). Therefore, in the above-described embodiment, the contents stored in the RAM 202b are not cleared unless both the clear signal and the confirmation signal are received. Therefore, as shown in the timing chart of FIG. 10, in the pachinko machine according to the above-described embodiment, the contents stored in the RAMs 202b and 302b are not cleared unless the initialization switch 102 and the erroneous operation prevention switch 103 are operated simultaneously. .
[0026]
As described above, in the pachinko machine according to the above-described embodiment, unless the power switch 108, the initialization switch 102, and the erroneous operation prevention switch 103 are operated together, the stored contents stored in the RAMs 202b and 302b are not erased. It is possible to more reliably prevent the stored contents from being cleared due to an erroneous operation of the initialization switch 102.
[0027]
In each of the above-described embodiments, the main controller 200 and the prize ball controller 300 are the only control devices that clear the stored contents of the RAM. However, the present invention is not limited to this, and the contents of the memory are cleared.
