Abstract

To provide a game machine in which a lighting element corresponding to a sensor is lit for a predetermined time when power supply is stopped so that the operation of the lighting element can be easily checked.SOLUTION: An optical sensor 59 is a sensor mounted on a game machine and the optical sensor 59 includes a light emitting portion 59A and a light receiving portion 59B. An LED 62 that is lit when the optical sensor 59 detects an abnormality is mounted on a main control board. In a normal state where the optical sensor 59 is not detecting any abnormality, both ends of the LED 62 have the same potential. Therefore, the LED 62 is turned off in the normal state. A power supply device 58 and the optical sensor 59 are connected with a first power supply wiring 68, and the power supply device 58 and the LED 62 are connected with a second power supply wiring 69. Since the timing of the voltage drop after the power supply from the power supply device 58 is stopped is different, the LED 62 can be lit for a predetermined time when the power supply is stopped.SELECTED DRAWING: Figure 5

Description

  The present invention relates to a gaming machine having a lighting element for visualizing a detection / non-detection state of a sensor on a substrate.

  Conventionally, in a gaming machine such as a pachinko machine or a slot machine, for controlling the operation of the gaming machine, for example, in order to visualize a detection state and a non-detection state of various components such as a CPU, a RAM, and a ROM, and mounted sensors. (Main control board and sub-control board) on which the lighting elements are mounted are housed inside a synthetic resin board case.

  The lighting element that reports the state of the sensor is used to notify the operating state of the gaming machine by lighting when various sensors mounted on the gaming machine detect a change in the state of the gaming machine. For example, when a loading sensor that detects that a medal has been inserted detects that a medal has been inserted into the medal insertion slot, a corresponding lighting element is turned on to notify that the medal insertion has been detected by the sensor. Similarly, when the payout sensor that detects that a medal has been paid out detects that the medal has been paid out from the hopper, a sensor that turns on the corresponding lighting element to notify that the medal payout is detected by the sensor is provided. is there. By providing the lighting element corresponding to the sensor in this manner, for example, in the case where the lighting element does not light even though a medal is inserted, it is easy to find out that a short circuit has occurred or that the sensor has been tampered with. it can.

  A gaming machine having a function of notifying the detection by such a sensor by a lighting element is provided with an illuminating device (LED) on a control board, as disclosed in Patent Document 1, for example, and the lighting of the illuminating device causes a sensor of a device to be provided. Gaming machines capable of easily notifying the detection by the game machine have been proposed.

JP 2009-34424 A (see paragraphs 0088 to 0089, etc.)

  However, when a corresponding lighting device (LED) is turned on when the sensor enters a predetermined detection state as in Patent Literature 1, if a failure occurs in the LED, the detection state of the sensor may not be notified. . In this case, the LED may be turned on to confirm that the LED is operating normally. For example, if the LED is turned on when the door is opened or when the power is turned on, an abnormality may occur in a portion corresponding to the LED. May be mistaken for the occurrence of Further, it is conceivable to turn off the LED when the sensor is in the detection state and turn on the LED when the sensor is not detected, but this is not appropriate from the viewpoint of power consumption and component life.

  The present invention has been made in view of the above-described problems, and it is possible to easily confirm the operation of a lighting element by lighting a lighting element for a predetermined time in response to an output of a sensor when power supply is stopped. The purpose is to do.

  In order to achieve the above object, a gaming machine according to the present invention includes a gaming machine, a control board on which control means for controlling the progress of the game is mounted, and a signal output by detecting a change in a state relating to the progress of the game. A sensor to be turned on, at least one lighting element mounted on the control board, receiving the signal, and lighting; a power supply for supplying power to the control board, the sensor, and the lighting element; and a power supply operation by the power supply being turned on. A power switch for turning off the power switch, and when the power supply to the sensor is stopped by turning off the power switch, the lighting element is turned on for a predetermined time.

  According to this configuration, when the power supply is stopped by turning off the power switch, the lighting element is turned on for a predetermined time, so that the operating state of the lighting element can be easily confirmed by turning on the lighting element. In addition, when there are a plurality of types of sensors, by providing a lighting element corresponding to each of the various sensors, the lighting elements corresponding to the various sensors are turned on in the lighting order determined when the power supply is stopped, so that each of the various sensors is turned on. The operation status of the corresponding lighting element can be efficiently confirmed.

  Further, the lighting element includes one terminal and the other terminal, and while the power is supplied to the sensor by turning on the power switch, the one end and the other end are held at the same potential, and By turning off the power supply to the sensor, the logic value of the output terminal of the sensor from which the signal is output is inverted, so that the potential of the other end changes and the potential of the one end changes. May change at a rate different from the rate of change of the potential at the other end, so that a potential difference greater than or equal to a specified value occurs at the one end and the other end, and a current flows through the lighting element to light the lighting element.

  According to this configuration, it is not necessary to prepare a separate component or control for lighting the lighting element, and the lighting element can be turned on for a predetermined time when the power supply is stopped by an inexpensive configuration.

  Further, the gaming machine includes a housing having an open front and a front door for opening and closing an open portion of the housing, and the power switch is disposed so as to be operable when the front door is opened. The lighting element may be turned on by the signal output by the sensor detecting a change in state other than the opening / closing operation of the front door.

  According to this configuration, since the power switch can be operated only when the front door is opened, when the power supply is stopped by turning off the power switch, a state change other than the opening and closing operation of the front door is simultaneously detected. The operating state of the lighting element corresponding to the sensor can be easily confirmed by lighting the lighting element.

  The power supply device may further include a first power supply line connecting the sensor to the power supply, and a second power supply line connecting the lighting element to the power supply and being different from the first power supply line.

  According to this configuration, since the sensor and the lighting element are connected to the power supply through different wirings, the timing of stopping the power supply to the sensor and the lighting element can be different, so that the lighting element is turned on when the power supply is stopped. Can be. In the case where there are a plurality of types of sensors and a lighting element is provided corresponding to these sensors, a different power supply for each sensor should be used as a first power supply wiring for connecting various sensors to a power supply. Accordingly, when the power supply is stopped, the lighting elements corresponding to the respective sensors can be lit in a predetermined order.

  Further, the sensor may be an optical sensor including a light receiving unit and a light emitting unit.

  According to this configuration, the sensor that is particularly liable to be fraudulently configured by the optical sensor, which is a non-contact sensor, can check the operation of the sensor effectively to prevent fraudulent behavior.

I do.

(Main control board)
Next, the main control board 63 will be described.

  The main control board 63 has various functions realized by executing a program stored in the ROM 67 and various functions realized by controlling hardware.

  The main CPU 61 selects one of a plurality of gaming states of the slot machine 1 depending on the type of a winning combination group (having one or more combinations) as a winning combination, winning or non-winning of the combination. The game of the slot machine 1 is controlled to the state.

  Further, the main CPU 61 adjusts the payout rate (the number of obtained medals / the number of inserted medals × 100 [%]) based on a predetermined setting change operation for the power switch 50, the change processing start switch 56, and the reset switch 52. Settings (settings 1 to 6) are changed.

  Further, the main CPU 61 selects one role lottery table from a plurality of role lottery tables based on the type of the controlled game state and the set values (Setting 1 to Setting 6). This winning combination lottery table stores, for each of a plurality of previously established winning combination groups, a winning combination group and a range of a lottery value in which the winning combination group is won in the combination drawing.

  In addition, when the start switch 19 is operated by the player, the main CPU 61 generates a random number for a combination lottery within a predetermined range, and uses the generated random number value as a lottery value at a timing when the start switch 19 is operated. Extract. Then, the main CPU 61 determines whether or not the winning combination group has been won, using the selected winning combination lottery value table and the extracted lottery values.

  When the start switch 19 is operated by the player, the main CPU 61 starts the rotation of each of the reels 13L, 13M, 13R, and detects the detection signals of the left / middle / right position sensors 55L, 55M, 55R, and the left / right signals. Based on the number of pulses supplied to each of the reel motors 14L, 14M, 14R for driving the middle / right reels 13L, 13M, 13R, the rotational positions of the left / middle / right reels 13L, 13M, 13R are detected, respectively. When all the reels 13L, 13M, and 13R rotate at a constant speed, the main CPU 61 enters a state in which the operation of each of the stop switches 21L, 21M, and 21R is accepted as an effective operation. When the player operates the stop switches 21L, 21M, 21R in this state, the main CPU 61 determines the detected rotational positions of the left, middle, and right reels 13L, 13M, 13R and the stop switches by the player. Based on the operation mode of 21L, 21M, 21R (for example, the pressing order and the operation timing) and the result of the lottery result, each reel is set within a predetermined number of sliding frames (pullable range: usually, a maximum of 4 frames). Stop control is performed so that 13L, 13M, and 13R stop.

  After the rotation of all the reels 13L, 13M, 13R is stopped, the main CPU 61 determines that the symbol combination of the winning line of the reels 13L, 13M, 13R corresponds to the winning combination group that has been won by the lottery. Is determined, and if the symbol combination of the winning line is a symbol combination corresponding to the winning combination, it is determined that the winning combination has been won, and if not, it is determined that the winning combination has been lost. When the main CPU 61 determines that the winning combination forming the winning combination group won by the winning lottery is won, if the winning is a winning combination with a medal payout, the main CPU 61 operates the hopper unit 43 to determine the winning combination. The medals are paid out according to the corresponding payout number. However, when the stored number of credit medals has not reached the upper limit value (for example, 50 in this embodiment), the main CPU 61 increases the number of credit medals by the number of payouts.

  The main CPU 61 controls the operation of the medal selector 48 to switch between medal acceptance and non-medal acceptance.

  In addition, the main CPU 61 determines whether the set value, the game state, the information on the result of the lottery, the information on the symbol determination result, the rotation / stop state of each of the reels 13L, 13M, 13R, the payout state of the medals, the opening / closing of the front door 5, and the like. Various kinds of information such as data representing the state of the slot machine 1 such as the state, the error state of the slot machine 1, and information relating to the operation of operating devices operated by the player such as the stop switches 21L, 21M, 21R, the start switch 19, etc. A command to be transmitted to the sub control board 73 (sub CPU 71) is generated, and the generated command is transmitted to the sub CPU 71 of the sub control board 73. The command is transmitted from the main control board 63 to the sub control board 73 in one way.

(Sub control board)
Next, the sub control board 73 will be described. The sub-control board 73 receives the command transmitted from the main control board 63 and performs an effect according to the operation and the state of the main control board 63. The sub-control board 73 has various functions realized by executing a program stored in the memory 75 and various functions realized by hardware.

  The sub CPU 71 receives commands including various data transmitted by the main control board 63 (main CPU 61). Then, the sub CPU 71 determines the contents of the effect according to the received command, and performs, for example, display control for displaying an image such as a moving image on the liquid crystal display 27 or a speaker according to the determined effect. It controls the output of sound from 31L and 31R and controls the light sources of the upper lamp unit 33 and the lower lamp units 37L and 37R to blink simultaneously or individually.

Then, the lighting of the light emitting section 59A is detected by a light receiving section (phototransistor) 59B constituting the optical sensor 59, and the light receiving section 59B is turned on, and a current is supplied from the power supply device 58 to the ground potential side via the light receiving section 59B. Flows. That is, a High signal is output from the output end (emitter) of the light receiving section 59B of the optical sensor 59. The High signal output from the light receiving section 59B is input to the main CPU 61 via the buffer 81 via the harness 76 and the resistor 78, and in response to the High signal from the light receiving section 59B, the main CPU 61 displays on the credit display 45. Keep the number unchanged. At this time, since both ends of the LED 62 are set at the same potential as the emitter of the light receiving portion 59B by the pull-up resistor 77, no current flows and the LED 62 remains off.

  When medals are paid out while the power is supplied from the power supply device 58 while the power switch 50 is turned on, the medals pass between the light emitting portion 59A and the light receiving portion 59B, so that the optical sensor 59 is provided. Is blocked, and the output end (emitter) of the light receiving unit 59B is inverted to Low, so that a Low signal is output from the light receiving unit 59B. The Low signal output from the light receiving unit 59B is input to the main CPU 61 via the buffer 81 via the harness 76 and the resistor 78, and in response to the Low signal from the light receiving unit 59B, the main CPU 61 Subtracts the number displayed on the credit indicator 45 and displays it, and in the case of payout based on winning, subtracts the number displayed on the payout indicator (not shown). At this time, a current flows through the current-carrying paths of the step-down circuit 70, the LED 62, the harness 76, the resistor 79, and the ground 80, and the LED 62 is turned on. Therefore, if the reception of the Low signal by the main CPU 61 is based on the payout of medals based on the payout command of the main CPU 61, it can be understood that the lighting of the LED 62 is normal. On the other hand, if the reception of the Low signal by the main CPU 61 is due to an incorrect payout of medals not based on the payout command of the main CPU 61, the main CPU 61 can determine that the lighting of the LED 62 is abnormal.

  On the other hand, when the power supply from the power supply device 58 is stopped by turning off the power switch 50, the voltage of the optical sensor 59 drops, the light emitting unit (LED) 59A of the optical sensor 59 turns off, and the light emitting unit 59A turns off. By doing so, the output end (emitter) of the light receiving section 59B is inverted to Low, so that a Low signal is output from the light receiving section 59B. At this time, even if the power supply of the power supply device 58 is stopped due to the turning off of the power switch 50, due to the delay time due to the LC component constituting the step-down circuit 70 or the delay time due to the difference in wiring between the power supply device 58, the optical sensor 59 and the LED 62. The output voltage of the step-down circuit 70 does not immediately decrease, but the voltage supplied to the LED 62 gradually decreases with a predetermined time delay. For this reason, the state where the current flows through the current-carrying path of the step-down circuit 70, the LED 62, the harness 76, the resistor 79, and the ground 80 is maintained by the Low signal of the light receiving unit 59B. Therefore, for a while after the power supply by the power supply device 58 is stopped, current continues to flow through the LED 62, and the LED 62 continues to be turned on. Thereafter, the voltage supplied from the power supply device 58 to the LED 62 also gradually decreases, and after a predetermined time determined by the above-described delay time, when the power supply voltage to the LED 62 falls below the voltage necessary to maintain the lighting state, the LED 62 is turned off. Turns off. Thus, after the power switch 50 is turned off and the power supply by the power supply device 58 is stopped, the LED 62 is turned on for a predetermined time. At this time, since the main CPU 61 is in the reset state due to the drop in the power supply voltage, the main CPU 61 does not perform the subtraction processing of the credits and the number of payouts.

  As described above, after the power supply by the power supply device 58 is stopped due to the turning off of the power switch 50, the light emitting unit of the optical sensor 59 is compared with the timing until the power supply required to maintain the lighting state of the LED 62 is stopped. Since the timing until the power supply to 59A is completely stopped is earlier, the LED 62 can continue to be lit even after the power supply is stopped. This timing difference is due to the fact that power is supplied to the LED 62 through the step-down circuit 70 as described above, and the wiring connecting the power supply device 58 to the optical sensor 59 and the LED 62 is different (first power supply). Due to the wiring 68 and the second power supply wiring 69), the voltage of the LED 62 is shorter than the time required for the voltage of the optical sensor 59 to completely drop and the light emitting section 59A to turn off and the output of the light receiving section 59B to be inverted to Low. The time required for the voltage to drop below the voltage required to maintain the lighting state is longer.

  Further, the first power supply wiring 68 is configured to be different depending on the type of the optical sensor 59 (the input sensor 53, the payout sensor 54, and the left / middle / right position sensors 55L, 55M, and 55R). Depending on the type, for example, it is also possible to make settings such that the LED 62 is turned on at different times, such as turning on the LED 62 in a preset order when the power supply is stopped. By doing so, the lighting order of the LEDs 62 is determined, so that the order of gaze can be considered, and it is easy to recognize whether or not the LEDs 62 have been turned on.

  Therefore, according to the above-described embodiment, when the power supply from the power supply device 58 is stopped by turning off the power switch 50, the LED 62 is turned on for a predetermined time, so that it is confirmed that the LED 62 is operating normally. It can be done easily. In addition, when the power supply is stopped, the LEDs 62 corresponding to the various sensors are turned on in a predetermined order, so that the various sensors and the LED 62 can be inspected efficiently.

  In addition, by using different wiring for the power supply between the power supply device 58, the optical sensor 59, and the LED 62, the LED 62 can be turned on only when the power supply is stopped, using only a circuit configuration, without preparing separate components or control. Further, the first power supply wiring 68 for connecting the power supply device 58 and the optical sensor 59 is supplied with different wiring depending on various sensors (the input sensor 53, the payout sensor 54, and the left / middle / right position sensors 55L, 55M, 55R). By changing the voltage, when the power supply is stopped, the LEDs 62 corresponding to the various sensors can be turned on in a predetermined order. By doing so, the lighting order of the LEDs 62 is determined, so that the order of gaze can be considered, and it is easy to recognize whether or not the LEDs 62 have been turned on.

  Further, by turning off the LED 62 in the normal state where the optical sensor 59 does not detect a state change and turning on the LED 62 when the power supply is stopped, it can be easily confirmed that the LED 62 itself is functioning normally. .

  Note that the present invention is not limited to the above-described embodiment, and various changes other than those described above can be made without departing from the gist of the present invention.

  Further, in the above-described embodiment, the slot machine has been described, but the present invention is not limited to this, and the present invention can be applied to other gaming machines such as a pachinko machine.

  In the above-described embodiment, the step-down circuit 70 is provided between the power supply device 58 and the LED 62. However, another component or control may be provided. Any configuration can be used as long as power can be continuously supplied to the power supply. For example, the configuration of the harness 76 may be different, or the distance between the components may be different.

  Further, the contents of the above embodiments can be appropriately combined. For example, in the above-described embodiment, the LED 62 is turned on when various sensors detect a predetermined state. However, instead of the LED 62, for example, a 7-segment LED or a light bulb constituting the display D can be used. is there.
