Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to an improvement in its power supply system.

  A ball ball game machine (a so-called pachinko machine) installed in a game machine installation store or the like uses a game ball (also called a game medium) to play a game. The borrowed game balls are launched to the board surface provided on the game board of the ball game machine, and a predetermined number of game balls are paid out each time the game balls enter a predetermined winning opening. The game balls to be paid out are called prize balls.

There are the following winning holes provided on the board of the ball game machine.
(1) Ordinary winning device (2) Start chucker (starting winning device)
(3) Attacker (Large winning device)
(4) Through chucker (winning chucker)

The start chucker (starting winning device) is also called a specific winning device. When a game ball is accepted by the start chucker (start prize-winning device) and enters the winning state, the prize ball is paid out and an electronic lottery is performed. In the case of winning, the game state is advantageous to the player from the normal state. Thus, the attacker (large winning device) is opened.
The attacker (large winning device) is also called a special winning device.

  The through chucker (winning chucker) does not pay out the winning ball directly, but is included in the winning slot in this specification. When it is detected that the game ball has passed through the through-chucker (winning chucker), an electronic lottery is performed. The time is released to make it easier for the game ball to enter the start chucker (start prize winning device). The game ball received by the through chucker (winning chucker) moves on the board as it is, and is received by another winning port or a discharge port (out port) described below.

  In addition to the prize opening, a discharge port (out port) is provided on the board surface of the ball game machine. The discharge port (out port) is an opening provided in the lower part of the guide rail (portion where the game balls are collected by gravity) arranged in a spiral shape to partition the game area on the board surface. Is for accepting a game ball that has not been accepted by any of the normal winning device, start chucker (start winning device), and attacker (large winning device), and discharging it out of the board.

  Pachinko machines and other gaming machines that are installed and used in pachinko parlors and other gaming venues are given a certain value to gaming media such as pachinko balls, and the gaming media acquired through games are exchanged for various prizes. can do. In the gaming machine, various drive devices such as a lamp device and a sound generation device that are operated based on the supply of the game medium, and a control circuit device (control) corresponding to control these drive devices are provided in the housing. And a sub-control unit), and when the player plays a game, they are appropriately operated to make the game full of fun. Further, in recent years, a variable symbol display device such as a liquid crystal image display device capable of variably displaying predetermined identification information (symbol) is built in, and when predetermined conditions are satisfied, the identification information is changed and then stopped and displayed. The thing which operates a symbol variable display apparatus has become mainstream. Such control is realized by transmitting a predetermined command from a control unit that mainly executes game processing to a sub-control unit that mainly executes effect processing.

  Due to laws and regulations governing gaming machines, the flow of commands from the control unit (main board) to the sub-control unit (sub-board) is one-way, and conversely, it is allowed to send a signal containing commands from the sub-control unit to the control unit. It has not been.

  In such one-way communication, even when a command cannot be received correctly, it is not possible to request retransmission. If many commands are lost, the sub-control unit will not produce effects, which will impair the player's interest.

JP, 2001-353265, A In a game machine with a maintenance power supply including a plurality of control devices provided with a memory which memorizes and holds the contents of game information by supplying electric power from an auxiliary power source which consists of a charging capacitor at the time of power-off.

  FIG. 8 shows a power supply system diagram in the case of a conventional gaming machine. This figure is a schematic block diagram showing only the parts necessary for explanation. For the operation of each unit and the meaning of symbols in the figure, refer to the description related to FIG.

  The first power supply circuit PS1 of the control unit 40 receives the first common power supply V1 from the power supply substrate 60, generates power for operation of the CPU of the control unit 40 and other electronic circuits L1, and supplies them to them.

  The second power supply circuit PS2 of the sub-control unit 40b receives the second common power supply V2 from the power supply board 60, generates power for operation of the CPU of the sub-control unit 40b and other electronic circuits L2, and supplies them to them.

  Therefore, although common in that the power supply is received from the power supply substrate 60, the first common power supply V1 and the second common power supply V2 that are generated are separate power supplies. The sub-control units 40b are independent of each other. In other words, even if a failure occurs in one of the power supply systems of the control unit 40 and the sub-control unit 40b, such a failure may not occur in the other. On the other hand, as described above, since the command is transmitted from the control unit 40 to the sub-control unit 40b, the control unit 40 and the sub-control unit 40b depend on each other with respect to signal processing (specifically, The sub-control unit 40b is subordinate to the control unit 40).

  As described above, the relationship between the control unit 40 and the sub-control unit 40b is different with respect to the signal processing system and the power supply system. For this reason, it is possible that the processing will be frustrated between the control unit 40 and the sub-control unit 40b. Specifically, in the configuration of FIG. 8, there is a possibility that the sub control unit 40 b misses a command from the control unit 40. If the command is lost, the effect by the sub-control unit 40b is not performed, and the interest of the player is impaired.

  The above problem will be described in detail with reference to the timing chart of FIG.

(1) FIG. 9A shows a case where an abnormality such as a momentary power interruption or a power interruption occurs in the second common power supply, that is, the power supply system of the sub-control unit 40b. No abnormality has occurred in the first common power supply, that is, the power supply system of the control unit 40. The first common power source and the second common power source are respectively connected to the plurality of substrates via a plurality of harnesses and substrates (these are not shown in FIG. 8). For this reason, these common power supplies are easily affected by noise, etc. Also, if a short circuit or abnormal operation occurs in either the harness or the board, an excessive current flows, causing an instantaneous voltage drop (instantaneous interruption) or constant The power supply voltage may drop (power outage) during the period. In FIG. 9A, the power supply voltage decreases from time t12 to t13.

(2) FIG. 9B shows the voltage of the second common power supply 2 after the power switch (not shown) is turned off (thereby, the output voltage of the power supply board 60 is turned off), and before the first common power supply. This shows the case where is lowered. As described above, each power supply system is independent, and a plurality of different substrates are connected to each other in the first common power supply and the second common power supply, so that the output voltage of the power supply substrate 60 is simultaneously turned off. Even so, the voltages of the first common power supply and the second common power supply 2 do not always drop in the same way. For example, the power supply of the second common power supply quickly decreases due to the fact that many boards are connected to the second common power supply, the power consumption of the connected boards is higher, or the power supply of the second common power supply is changed to the first common power supply. It is possible that more capacitors are mounted on the connected substrate, and the voltage of the first common power supply slowly decreases because more electric charge is accumulated in the capacitors. In FIG. 9B, the power supply voltage of the first common power supply decreases from time t26 to t28, while the power supply voltage of the second common power supply decreases from time t23 to t25. However, t23 to t25 <t26 to t28.

  9A and 9B, the smaller the number at the end of the time t, the past (left side), and the larger the number, the future (right side).

  In FIG. 9A, t11 indicates the command transmission start of the control unit 40 and the command reception start of the sub-control unit 40b (ignoring the time required for command transmission). t12 indicates the start of instantaneous power interruption, and t13 indicates the end. t14 indicates the command reception restart of the sub-control unit 40b (a certain time is required until the command reception is restarted even if the power supply voltage returns). t15 indicates the command transmission end of the control unit 40 and the command reception end of the sub-control unit 40b.

  In FIG. 9B, t21 indicates the command transmission start of the control unit 40 and the command reception start of the sub-control unit 40b. t22 indicates the timing of turning off a power switch (not shown). t23 indicates the start of lowering the voltage of the second common power supply, t24 indicates the timing at which the voltage of the second common power supply reaches the voltage at which the CPU or the like stops its operation, and t25 indicates the voltage of the second common power supply. Indicates the timing when becomes zero volt (ground potential). t26 to t28 are timings corresponding to the above-described t23 to t25 with respect to the first common power supply.

  Now, in FIG. 9 (a), an instantaneous interruption occurs from time t12 to t13, so the command reception function of the sub-control unit 40b is impaired from time t12 to t14. Therefore, the command transmitted during this time will be missed.

  In addition, in FIG. 9B, the operation of the sub-control unit 40b stops first, so that the command transmitted from time t24 to t27 is missed.

  Note that even if the operation of the control unit 40 becomes unstable due to a momentary interruption, power interruption, or the like, the problem of missing a command does not occur.

  As described above, according to the power supply system of the conventional gaming machine, the operation of the sub-control unit 40b becomes unstable due to a momentary power interruption, power-off, etc., so that the command from the control unit 40 is missed. Will occur.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a gaming machine in which a sub-control unit does not miss a command even if an instantaneous interruption, power interruption, or the like occurs.

  A gaming machine according to the present invention executes a control related to a game including an internal lottery process, generates and transmits a predetermined command, and receives the command generated by the control unit based on the control unit.

The power supply board generates a third common power supply having a voltage different from the second common power supply instead of the second common power supply.
A power supply circuit for receiving the third common power supply and generating the second common power supply;
The second wiring may be connected to the output terminal of the power supply circuit.

  There may be provided a backflow prevention means provided between the second common power supply and the output terminal of the voltage adjusting means for preventing the first common power supply from wrapping around the second common power supply.

  The voltage adjusting means may include a plurality of diodes connected in series, and a forward voltage drop due to the plurality of diodes may correspond to the potential difference absorbed by the voltage adjusting means.

  According to an embodiment of the present invention, a potential difference between the first common power source and the second common power source is generated with respect to the first common power source for the control unit and the second common power source for the sub control unit, which are generated in the power source substrate. And a voltage adjusting means for flowing a current from the first wiring to the second wiring when the voltage of the second common power supply decreases, so that when there is a momentary power interruption or when the power is turned off However, the sub-control unit does not become unstable or inoperable, and the problem that the sub-control unit misses the command does not occur.

  HB1 is a wiring that connects the output terminal of the first common power supply V1 of the power supply substrate 60 and the input terminal of the voltage adjusting means VA. HB2 is a wiring that connects the output terminal of the voltage adjusting means VA and the input terminal of the second power supply circuit PS2.

  According to the configuration of FIG. 5, there is no problem that a command is missed when the power is cut off or the power is turned off. As described above, the cause of missing the command is an instantaneous interruption of the power supplied to the sub-control unit 40b or a rapid voltage drop. However, according to the embodiment of the invention, the configuration shown in FIG. Even if such a phenomenon occurs, the current flows from the first common power supply V1 to the second common power supply V2, so that the operation of the sub-control unit 40b does not stop, so that the command is not missed.

  A description will be added with reference to the timing chart of FIG. 6 corresponds to FIG. 9. For the meanings of the reference numerals in the figure, refer to the description regarding FIG. 9 described above.

  Even if the second common power supply V2 is momentarily interrupted from time t12 to t13 as shown by the dotted line in FIG. 6A, current flows from the first common power supply V1 to the second common power supply V2 by the voltage adjusting means VA. The voltage received by the second power supply circuit PS2 does not vary as shown by the solid line in FIG. Further, as shown by the dotted line in FIG. 6B, even if the voltage V2 of the second common power supply V2 quickly decreases from the time t23, the voltage adjustment means VA causes the current from the first common power supply V1 to the second common power supply V2. Therefore, the voltage received by the second power supply circuit PS2 is maintained until the drop of the first common voltage at time t26 as shown by the solid line in FIG. Therefore, the sub-control unit 40b can operate in the same manner as the control unit 40, and there is no problem of missing a command.

The number of diodes of the voltage adjusting means VA (three in the example in the figure) is obtained by the following equation. If the following equation is satisfied, the second common power supply V2 serves as a power supply for the second power supply circuit PS2 during normal operation.
First common power supply voltage V1-Vf1 × (number of diodes) <second common power supply voltage V2-Vf2
However, Vf1: Forward drop voltage of the diode of the voltage adjusting means VA, Vf2: Forward drop voltage of the diode of the backflow prevention means D.

  Further, the left side of the above formula is equal to or higher than the specified input voltage minimum value of the second power supply circuit PS2 (threshold that a normal voltage can be output above this value, but only a voltage lower than the specified value can be output below this value). It is necessary to be.

  Further, from the viewpoint of the output capacity of the power supply substrate 60, even when the voltage adjusting means VA is passing current from the first common power supply V1 to the second power supply circuit V2, the current consumption value of the first common power supply V1 is the power supply substrate 60. Must be less than or equal to the maximum allowable current value.

  The voltage V1 of the first common power supply V1 and the voltage V2 of the second common power supply V2 may be the same. In this case, the voltage adjusting unit VA may not have a function of absorbing the potential difference.

  As shown in FIG. 7, the power supply substrate 60 generates a third common power supply V3 having a voltage different from the second common power supply V2 instead of the second common power supply V2, and receives the third common power supply V3 from the sub-control unit 40b. A third power supply circuit PS3 that generates a common power supply V2 may be provided. The third power supply circuit PS3 is, for example, a three-terminal regulator.

  In the configuration of FIG. 5, it is necessary that the voltage V1 ≧ the voltage V2. On the other hand, according to the configuration of FIG. 7, even when the voltage of the first common power supply V1 generated in the power supply substrate 60 is lower than the others, the third common power supply V3 is converted into the first common power supply by the third power supply circuit PS3. The configuration of FIG. 5 can be applied by converting the second common power source V2 lower than V1. That is, in the configuration of FIG. 7, the voltage V1 = the voltage V3 or the voltage V1 <the voltage V3. Therefore, the degree of freedom in designing the output voltage value of the power supply substrate 60 is increased, which is advantageous in terms of design and manufacturing.

  According to the embodiment of the invention, when there is a momentary power interruption or when the power is turned off, the sub control unit does not become unstable or inoperable, and the sub control unit misses the command. do not do. Since the command is not missed, the state of the main system control by the control unit, that is, the gaming state and the state of the effect control by the sub control unit do not mismatch, and the consistency between the two can be taken. In particular, the processing related to the liquid crystal display device is very effective in that the symbols are appropriately displayed there.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
