Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a ball game machine equipped with a movable accessory for assisting production.
  Conventionally, among the various ball game machines, a so-called first type pachinko game machine is used while changing a plurality of symbols in a display area such as a liquid crystal display provided substantially at the center of the game board. Display (hereinafter, such display is referred to as “symbol change” or “change display”). This gaming machine shifts to a special game called so-called jackpot where more prize balls can be obtained than a normal game when a combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific mode. It is known as a thing (for example, refer patent document 1). The variation display of the symbols in the display area is not just a variation display of multiple symbols, but the time of variation display in a state where it is a big hit if one more symbols are aligned, as in the so-called reach variation screen. For example, it is designed to increase the player's expectation such as making it longer than usual.
Further, in recent years, the aspect of the game effect is not limited to the content of the screen display content, and an increasing number of models are provided with a mechanically operated effect structure called a so-called movable accessory on the game board surface or around the liquid crystal screen (for example, Patent Document 2). While manufacturers are constantly pursuing innovative gameplay and production, not only will the production of such novelty be realized with the contents displayed on the LCD screen, but also the operation of mechanical elements. Is an attempt.
JP 2003-230714 A Japanese Patent Laid-Open No. 2007-14408
  The operation of such a movable accessory is controlled by driving an actuator such as an electric motor. However, since the movable accessory and its operating mechanism are made of a structural body, the operating part deteriorates with aging. As this secular change progresses, the control amount initially set for the movable accessory and the actual operation amount are not matched, and there is a possibility that the role of assisting the production as the movable accessory cannot be sufficiently achieved. In addition, due to the variation among individual movable objects, it may be assumed that the consistency of a certain gaming machine is not satisfied regardless of whether there is a secular change. On the other hand, it is costly to repair or replace the movable accessory whenever the consistency with the control is deviated.
  The present invention has been made in view of such a problem, and in a ball game machine that assists production by controlling a movable accessory, consistency with the control is achieved regardless of individual differences or aging. The purpose is to be able to secure longer.
  In order to solve the above-described problems, a bullet ball game machine according to an aspect of the present invention includes a game board in which a game area into which a game ball is inserted is formed, and a movable combination disposed so as to be movable up and down with respect to the game area. A lifting mechanism that lifts the object while supporting the movable accessory and temporarily releases the support at a predetermined position and lowers it to the target lowering position by gravity, a control unit that drives and controls the lifting mechanism, a target A descent detection sensor disposed at the descent position and detecting that the movable accessory has descended to the target descent position. The control unit measures the time required for the movable accessory to descend at a predetermined timing after the power is turned on, and sets a reference value for determining a normal descent time based on the measured time, while the movable part is movable during the game. The descent time is calculated for each descent of the accessory, and when the descent time exceeds the reference value, a predetermined abnormality process is executed.
  The “descent due to gravity” mentioned here may be, for example, free fall or descent due to sliding down. The movable accessory is raised again by the elevating mechanism after being lowered by gravity. The “predetermined timing” may be, for example, immediately after turning on the power to the gaming machine, or may be a timing at which the movable accessory descends in the game process after turning on the power. The “reference value” can be set to a value that is larger by a predetermined amount than the descent time measured at the predetermined timing and is assumed not to exceed if normal. The “reference value” may be set based on the descent time by providing the predetermined timing once, or may be set based on the average value or the maximum value of the descent time by providing a plurality of times. . The “predetermined abnormality process” may be a process for notifying the user that the reference value has been exceeded, for example, by an error notification, by voice or display, etc., or a process for stopping a game. It may be.
  In this aspect, an effect is produced by raising and lowering the movable accessory. The movable accessory is supported by the elevating mechanism and rises, but when the support is released, it is lowered by gravity. Since the movable accessory descends due to its own weight, when it is normal, the descent time required from the descent start to the target descent position is substantially constant. For this reason, effect control by a movable accessory is performed in consideration of this descent time. According to this aspect, since the descent time of the movable accessory is measured and the reference value is set every time the power is turned on, even if the movable accessory or its lifting mechanism changes over time, the reference reflecting the change over time Updated to value. Even if there is an individual difference such as a movable accessory, a reference value suitable for the movable accessory is set after the power is turned on. That is, every time the power is turned on, correction for absorbing the individual difference is made for the descent time of the movable accessory, so that the operation can be matched with the effect control regardless of the individual difference. At the same time, correction for absorbing aging deterioration is performed, so that consistency can be maintained for a long time.
  Specifically, the elevating mechanism has a wire rod that suspends a movable accessory, a hoisting gear that winds the wire rod by rotation, a meshing portion that meshes with the hoisting gear, and a toothless portion that releases the meshing. A drive gear may be included. When the driving gear is driven in the forward direction, the position of the movable accessory is raised by the hoisting force of the hoisting gear, and when the meshing position of the hoisting gear and the driving gear reaches the missing tooth portion, the meshing is temporarily performed for the missing tooth period. The movable combination may be configured to be released by gravity due to the release of the hoisting gear. The control unit controls the rotational drive of the drive gear.
  As used herein, the “wire” may be, for example, a metal wire having a certain degree of rigidity in the extending direction, or may be a rope or a thread. The movable accessory is supported so as to be suspended by this wire. When the drive gear rotates in the forward direction, the rotational force is transmitted to the hoisting gear to wind up the wire, and the movable accessory is raised. When the drive gear further rotates in the forward direction and the meshing position with the hoisting gear reaches the tooth missing portion, the hoisting gear rotates in the reverse direction to lower the movable accessory. The control unit measures this descent time.
  More specifically, a descent start position sensor that detects that the meshing position of the hoisting gear and the drive gear has reached a predetermined position at or near the missing tooth portion may be further provided. The control unit may calculate the descent time of the movable accessory based on the detection timing by the descent start position sensor and the detection timing by the descent detection sensor. These descent start position sensor and descent detection sensor may be composed of, for example, a photosensor provided with a light emitting element and a light receiving element. In particular, for the descent start position sensor, the structure of the hoisting gear itself can be used, such as the reflection of light by the meshing part or the transmission of light by the missing tooth part. Regarding the descent time of the movable accessory, when the descent start position sensor detects that the meshing position of both gears has reached the tooth missing part, the detection timing of the descent start position sensor and the detection of the descent detection sensor It can be calculated from the time difference from the timing. Further, when the descent start position sensor detects that the meshing position of both gears has reached a predetermined position near the tooth missing portion, the meshing position of both gears reaches the tooth missing portion from the predetermined position. The descent start timing of the movable accessory may be calculated in consideration of time. The descent time of the movable accessory may be calculated from the time difference between the descent start timing and the detection timing of the descent detection sensor. Alternatively, even if the descent start position sensor detects that the meshing position of both gears has reached the predetermined position, the movable position is determined by the time difference between the detection timing of the descent start position sensor and the detection timing of the descent detection sensor. You may make it substantially evaluate the fall time of an object.
  In order to hold the movable accessory at the target lowering position, the mechanism may be provided with a locking portion that receives the movable accessory from below. The “locking portion” may include a cushioning material for stably receiving the movable accessory. In any case, a bounce occurs when the movable accessory collides with the locking portion, and in some cases, the descent detection sensor may cause chattering due to the bounce. On the other hand, chattering itself usually does not last so long. Therefore, the control unit may set the reference value by adding the convergence time of chattering due to the bounce after the descent of the movable accessory to the locking unit to the descent time measured at the predetermined timing. The “chattering convergence time” may be set by trying to lower the movable accessory several times after the power is turned on, or may be set by sampling during the performance of the game. Since the convergence time of chattering is considered in the reference value, it becomes clear that if the fall time exceeds this, it is no longer an influence of chattering. Thereby, the descent abnormality of a movable accessory can be determined and the abnormality process mentioned above can be performed appropriately.
  Furthermore, you may provide the effect display apparatus which has the display area which is provided in the predetermined position of the game area, and displays the predetermined effect image according to a game state. The movable accessory is configured to include a main body extended so that the display area can be bridged to the left and right when the elevator is raised and lowered, and support portions provided on both left and right ends of the main body, and a pair of wire rods are provided on the left and right. In addition, each wire may suspend left and right support portions at the end opposite to the hoisting gear.
  The “effect display device” here may be constituted by a liquid crystal display, for example, or may be constituted by other display means such as a mechanical drum or LED. The movable accessory may assist the effect displayed on the effect display device.
  In this aspect, since the movable accessory is suspended by the left and right wire rods, the movable accessory is likely to be inclined, and problems such as being easily caught on the mechanism are likely to occur. For this reason, the effect of determining the abnormality by providing the reference value is remarkably exhibited.
  It should be noted that any combination of the above-described constituent elements and a representation of the present invention converted between a method, an apparatus, a system, and the like are also effective as an aspect of the present invention.
  According to the present invention, in a ball game machine that assists production by controlling a movable accessory, consistency with the control can be ensured for a longer time regardless of individual differences or aging.

  FIG. 3 is a diagram schematically showing a drive unit for a movable accessory.
  The drive unit 200 is attached to the back side so as to sandwich the periphery of the central opening of the game board 50 between the center ornament 64. The drive unit 200 is configured by arranging a movable accessory 140 and its elevating mechanism 204 in a substantially rectangular case 202 attached to the game board 50. In the center of the case 202, an opening 206 that is slightly larger than the central opening of the center ornament 64 is provided, and the display area 208 of the effect display device 60 installed on the back side is exposed.
  The movable accessory 140 is provided at the leading end of each arm 212, the accessory main body 210 disposed so as to be spaced forward from the case 202, a pair of arms 212 extending to the left and right of the accessory main body 210. The support portion 214 is included. On the left and right sides of the case 202, a pair of guide portions 216 are arranged so as to extend vertically so as to sandwich the opening 206, and left and right support portions 214 are slidably arranged. By providing the arm 212 so as to extend slightly forward from the support portion 214, the accessory body 210 protrudes forward. The accessory body 210 can move forward and backward by moving up and down to the front side of the display area 208, and when it advances into the display area 208, it bridges it together with the arm 212.
  The elevating mechanism 204 includes a pair of left and right wires 221 and 222 as wire rods that suspend the movable accessory 140, a pair of hoisting gears 223 and 224 that wind up each wire, and a drive gear 226 that rotates each hoisting gear. Consists of including. As illustrated, the hoisting gears 223 and 224 have the same structure, and are juxtaposed on the left and right above the opening 206 and mesh with each other. The drive gear 226 is arranged in parallel with one hoisting gear 224 and directly drives it. That is, the drive gear 226 is configured as an intermittent gear having a meshing portion 228 and a missing tooth portion 230. The driving gear 226 is driven by the electric motor 232, and meshes with the hoisting gear 224 at the meshing portion 228 to transmit the rotational driving force to the hoisting gear 224. The rotational driving force is also transmitted to the hoisting gear 223 via the hoisting gear 224. On the other hand, when the meshing position of the hoisting gear 224 and the driving gear 226 reaches the missing tooth portion 230, the meshing is released only during the missing tooth period, and the transmission of the rotational driving force is temporarily interrupted. In this embodiment, a stepping motor is employed as the electric motor 232.
The wire 221 wound around the hoisting gear 223 is connected to the left support portion 214 via the roller 233. On the other hand, the wire 222 wound around the hoisting gear 224 is connected to the right support portion 214 via the roller 234. Thus, the movable accessory 140 is stably suspended by the wires 221 and 222 on the left and right sides thereof. In the vicinity of the lower end of each guide portion 216, a rubber bush 236 as a locking portion is disposed, and serves as a cushioning material that receives the support portion 214 from below when the movable accessory 140 falls. A photo sensor 240 as a lowering detection sensor is disposed at the lower end of the right guide portion 216, and detects that the support portion 214 has been lowered and locked to the rubber bush 236. That is, the photosensor 240 is a transmissive photosensor, and the light emitting portion 241 and the light receiving portion 242 are disposed to face each other at the lower end portion of the guide portion 216. The light receiving unit 242 receives light from the light emitting unit 241. When the support part 214 is positioned at the bottom dead center due to the lowering of the movable accessory 140 and the light reception by the light receiving part 242 is interrupted, it is determined that the movable accessory 140 has reached its target lowering position. Further, a photo sensor 246 as a descent start position sensor is disposed in the vicinity of the drive gear 226. The photosensor 246 is also a transmissive photosensor, and the light emitting portion and the light receiving portion are disposed to face each other so as to sandwich the tooth base of the drive gear 226. The photo sensor 246 detects the missing tooth portion 230 when the drive gear 226 rotates and the light receiving portion receives light.
The movable accessory 140 stops at the standby position shown in FIG. 1 when not operating, and mechanically descends when it reaches a top dead center position slightly elevated during operation. The photo sensor 246 detects that the movable accessory 140 has been displaced to the standby position. That is, when the electric motor 232 further rotates several steps (for example, 5 steps) from the detection of the tooth missing portion 230 by the photosensor 246, the movable accessory 140 reaches the top dead center position. That is, at this time, the meshing position of the drive gear 226 and the hoisting gear 224 reaches the toothless portion 230, so that the meshing of both gears is released and the movable accessory 140 starts to descend. From such a configuration, the time when the photo sensor 246 is turned on and further rotated several steps in the forward direction is calculated as the timing at which the movable accessory 140 has moved up to its top dead center position, that is, the descent start timing. After the movable accessory 140 is lowered in this way, the drive gear 226 rotates in the forward direction and meshes with the hoisting gear 224 again to start rising again. When the movable accessory 140 rises from below and the missing tooth portion 230 is detected by the photosensor 246, it is determined that the movable accessory 140 has returned to the original standby position. When ending the operation of the movable accessory 140, the drive of the electric motor 232 is stopped when it is determined in this way that the movable accessory 140 has returned to the standby position.
  That is, the movable accessory 140 is held almost horizontally by being suspended by a pair of wires, and is moved up and down by the rotation of the hoisting gears 223 and 224. As shown in the figure, when the drive gear 226 rotates counterclockwise, which is the positive direction, the hoisting gear 224 meshing with the driving gear 226 rotates clockwise, and the hoisting gear 223 meshing therewith is further rotated counterclockwise. Rotate to. Thereby, each wire is wound up, and the position of the movable accessory 140 is raised. When each gear further rotates and the meshing position of the hoisting gear 224 and the drive gear 226 reaches the missing tooth portion 230, the meshing is temporarily released only during the missing tooth period, and the hoisting gears 223 and 224 are rotated freely. The movable accessory 140 descends due to the gravity. At this time, if the movable accessory 140 and its lifting mechanism 204 are operating normally, the movable accessory 140 descends to its target lowering position. Then, when each gear further rotates and the hoisting gear 224 and the driving gear 226 are engaged again, the movable accessory 140 starts to rise again. For production, the driving gear 226 is reversely rotated to gradually lower the movable accessory 140, and repeated raising and lowering by a predetermined amount, but the details are omitted.

Similarly, each functional block included in the sub-board 104 may be configured such that any one of them is mounted on the main board 102 instead of the sub-board 104.
  The entrance determination means 110 determines whether or not a game ball has entered each winning opening. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62, and when receiving the big winning opening winning information, determines that the game ball has won the big winning opening 66, and the general winning is obtained. When the information is received, it is determined that the game ball has won the general winning opening 72. When receiving the passage information, the ball entering determination unit 110 determines that the game ball has passed through the operation port 68.
  The success / failure lottery means 112 accepts a random number value to determine whether or not to shift to a special game that is more advantageous to the player than the normal game when the game ball enters the start port 62. Get as a value. For example, the success / failure lottery value is acquired from a value range from “0” to “65535”. The “random number” in the present application may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. The success / failure lottery means 112 holds a plurality of success / failure tables to be referred to in the success / failure determination. In the plurality of success / failure tables, the determination result of winning or losing is associated with the winning / losing lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 refers to a success / failure table for determination of success / failure based on a normal probability in normal times, and refers to a success / failure table in which the winning probability is higher than the normal probability when the probability changes. The success / failure lottery means 112 refers to any of the plurality of success / failure tables and determines whether or not the success / failure lottery value is a win. The determination result by the success / failure lottery means 112 is variably displayed in a special symbol form on the special symbol display device 61. In addition, a decorative symbol that shows the determination result by the success / failure lottery means 112 is displayed in a variable manner on the effect display device 60.
  The symbol determination unit 114 determines the stop symbol and the variation pattern of the special symbol to be displayed on the special symbol display device 61 according to the lottery result by the success / failure lottery unit 112. Moreover, the symbol determination means 114 determines the stop symbol of the normal symbol displayed on the normal symbol display device 59 by lottery. The stop symbol is a symbol to be displayed at the end of symbol variation. The symbol determination means 114 holds a symbol range table to be referred to in order to determine a special symbol or a normal symbol stop symbol, or a pattern determination table to be referred to in order to determine a variation pattern.
  The symbol determination means 114 acquires a symbol determination lottery value for determining a special symbol, and determines the stop symbol of the special symbol according to the determination result of the success / failure lottery means 112 and the symbol determination lottery value. The symbol determination unit 114 selects one of a plurality of variation patterns in accordance with the determination result of the success / failure lottery unit 112. The symbol determination unit 114 sends data indicating the determined stop symbol and variation pattern to the main display control unit 118 and the effect determination unit 132.
  The symbol determination means 114 stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the special symbol is variably displayed are defined. Multiple types of variation patterns have various variation times. That is, for each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol is stopped when the variation display time elapses.
  The symbol determining means 114 acquires a lottery random number for determining a normal symbol when the game ball passes through the operation port 68, and determines a stop symbol of the normal symbol according to the lottery random number. When the stop symbol of the normal symbol is a specific symbol, the opening / closing control means 124 expands the normal electric accessory at the start port 62 for a predetermined time.
  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 as a holding ball. The success / failure lottery value is accumulated until the number of holds reaches a predetermined upper limit. The upper limit of the number of holds is 4.
  The main display control means 118 causes the special symbol display device 61 to display the lottery result by the success / failure lottery means 112 as a special symbol variation display according to the variation pattern determined by the symbol determination unit 114. The main display control means 118 transmits the change start command and the change stop command to the effect display control means 134 at the timing of starting and stopping the change display of the special symbol, so that the main display control means 118 and the effect display are displayed. The fluctuation display by the control means 134 is synchronized and interlocked. The main display control means 118 displays the normal symbol variation on the normal symbol display device 59.
  The special game control means 120 controls the execution process of the special game when the result of the lottery determination by the success / failure lottery means 112 is a win. The special game is a game in which the opening / closing operation of the special winning opening 66 is continuously continued a plurality of times, and is constituted by one or a plurality of unit games with one opening / closing as a unit. The unit game is repeated up to 15 times, for example, and the grand prize opening 66 is opened for about 30 seconds in one unit game. If the number of continuations of the unit game has not reached the upper limit number, the special game control means 120 starts the next unit game after the end of the current unit game. When the upper limit number of unit games is exhausted, the special game is terminated.
  The specific game execution means 122 executes control for shifting the game state from the normal state to the specific game state, and control for returning the specific game state to the normal state. The specific game in the present embodiment has a probability change in which the winning probability of the winning / failing lottery is switched from a normal probability state to a high probability state, and a short time in which the symbol variation time is switched from a normal time to a short time.
  The specific game executing means 122 shifts the gaming state after the special game to the probability changing state when the winning / failing lottery value is a value to be shifted to the probability changing state. The probability variation state is continued until the next jackpot is generated in principle, and during that time, the probability of the hit determination by the success / failure lottery means 112 is maintained at a high value. In addition, the specific game executing means 122 shifts the game state to the time-shortened state after the special game regardless of the winning lottery value. The short time is continued until the number of changes in the special symbol after the special game reaches a predetermined number, for example, 100 times.
  The opening / closing control means 124 controls the opening / closing of the ordinary electric accessory at the start opening 62 and the special winning opening 66. When the normal symbol is stopped at a specific symbol, the opening / closing control unit 124 sends an opening instruction to the ordinary electric accessory solenoid 76 to open the start port 62. Further, the opening / closing control means 124 sends an opening instruction to the special winning opening solenoid 80 during the special game, and opens the special winning opening 66.
  The pattern storage unit 130 holds a plurality of variation pattern data in which a variation process from variation start to stop in variation display is defined as a variation pattern of the effect image including the decorative design. In the fluctuation pattern, a pattern for displaying a normal out symbol, a pattern for displaying a symbol out of reach after reaching a big win if one more symbols are aligned, and a jackpot symbol through a reach state are displayed. When the pattern is included. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. Each variation pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses. The effect determining means 132 selects the variation pattern of the effect image having the same variation time as that of the special symbol according to the variation pattern of the special symbol.
  The effect determining means 132 determines the combination of the stop symbols of the decorative symbols and their arrangement and variation pattern according to the result of the lottery by the success / failure lottery means 112, according to the stop symbol of the special symbol and the variation pattern of the special symbol. The effect determining unit 132 holds a symbol range table to be referred to in order to determine a stop symbol of a decorative symbol and a pattern table to be referred to in order to determine a variation pattern.
  The stop symbol of the decorative symbol is formed as a combination of three symbols. For example, when the determination result by the success / failure lottery means 112 indicates a shift to a special game, three symbols such as “777” and “111” are arranged. A combination is selected. In this case, it is preferable that the same numbers as the special symbols are selected as the numbers arranged as the decorative symbols. For example, when the special symbol is “3”, the decorative symbol is “333”. In the case where the determination result by the success / failure lottery means 112 indicates that the game does not shift to the special game, a combination that does not have three symbols such as “312” and “946” is selected. However, if the determination result is that the game does not shift to a special game, and a variation pattern of a special symbol indicating a loss with reach is selected, only one such as “191” or “727” is selected. Select a combination that does not have the same pattern. The effect determining unit 132 sends information about the stop symbol of the decorative symbol and the variation pattern of the effect image to the effect display control unit 134.
  The effect display control means 134 displays the effect image on the effect display device 60 in accordance with the selected variation pattern data as a result of the success / failure lottery by the success / failure lottery means 112. The effect display control means 134 further controls effect processing such as lighting and extinguishing of the game effect lamp 90 and sound output from the speaker 18.
  In accordance with an instruction received from the effect display control means 134, the accessory control means 136 controls the elevating mechanism 204 to drive and control the movable accessory 140 along the effect contents in the effect display device 60 and the blinking process of the game effect lamp 90. Make it work.
Next, characteristic functions and operations in the present embodiment will be described.
As described above, the elevating mechanism 204 of the movable accessory 140 is a suspension type using a pair of left and right wires 221, 222, and each wire is individually wound up by the hoisting gears 223, 224. . In such a configuration, the left and right wires can lift the left and right support portions 214 in a well-balanced manner, so that the movable accessory 140 can be moved up and down horizontally. It becomes difficult to make the movable accessory 140 function normally. On the other hand, since the movable accessory 140 and its elevating mechanism 204 have a mechanical structure, the operating portion thereof deteriorates over time. For example, the wires 221 and 222 may be stretched due to aging, and the support portion 214 may be worn due to sliding on the guide portion 216. The meshing state of each gear may also be affected by aging. In such a case, for example, the angle of the movable accessory 140 may be tilted from a horizontal state, and thus there is a possibility that a smooth lifting state cannot be realized. If the movable object 140 cannot be moved up and down due to being caught, the subsequent game cannot be continued. Alternatively, even if it is not possible to move the movable accessory 140 up and down, if the initially set control amount and the actual operation amount do not match at all, the movable accessory 140 may not be able to fulfill the role of assisting the production sufficiently. There is sex. In such a case, it is necessary to quickly detect this and perform error processing. In addition, due to the variation among individuals of the movable accessory 140, there may be a case where consistency with the control is not satisfied from the beginning even though there is no aging deterioration for a certain gaming machine. On the other hand, it is costly to repair or replace the movable accessory whenever the consistency with the control is deviated.
  Therefore, in this embodiment, the lowering state of the movable accessory 140 is monitored, the presence / absence of an abnormality in the movable accessory 140 and its lifting mechanism 204 is determined based on the lowering state, and an error is notified when it is determined as abnormal. . In addition, processing for correcting the determination criterion in a timely manner is performed so that the error notification is not frequently generated unnecessarily.
FIG. 5 is a diagram schematically illustrating the signal waveform of the photosensor before and after the descent of the movable accessory.
In the present embodiment, the accessory control means 136 controls the driving of the movable accessory 140 and executes an error notification process when an abnormality occurs in the driving state. Here, the descent time to the target descent position when the movable accessory 140 is freely dropped is detected, and when the descent time exceeds a predetermined error determination reference value, error information indicating control abnormality is produced. It is displayed on the display device 60.
  When the control state of the movable combination 140 is normal, the descent time of the movable combination 140 is considered to be a substantially constant value. In the illustrated example, the photosensor 246 detects the missing tooth portion 230 at time t0 and is turned on. The movable accessory 140 reaches top dead center at time t1 when the electric motor 232 rotates several steps therefrom, and falls by its own weight when the meshing state of the hoisting gear 224 and the driving gear 226 is released. At time t2, since the movable accessory 140 has been lowered to the target lowering position, which is the bottom dead center, the photo sensor 240 detects the support portion 214 and changes from on to off. However, since the support portion 214 bounces after colliding with the rubber bush 236, the photosensor 240 is chattered repeatedly turning on and off until time t3. Then, since the drive gear 226 further rotates and meshes with the hoisting gear 224 again, the photosensor 246 is turned off by the meshing portion 228 at the time t4 when the electric motor 232 rotates several steps from the meshing. Yes. As the movable accessory 140 rises again, the photosensor 240 is turned on at time t5. Note that the photosensor 246 is turned off at the time t4, whereas the photosensor 240 is turned on at a later time than the photosensor 240 at the time t5 because the support portion 214 is raised and the photosensor 240 is turned on. This is because it takes some time before the light shielding state is released.
  As described above, when the movable accessory 140 is operating normally, the movable accessory 140 starts to descend after the time T0 when the electric motor 232 rotates several steps after the photosensor 240 is turned on. Then, the target descent position is reached as time T1 elapses, and then chattering converges at time T2. Here, whether or not there is an abnormal operation of the movable agent 140 is determined based on whether or not the descent time of the movable agent 140 is normal. However, it is not possible to normally determine whether or not the movable agent 140 is lowered during the chattering period. . Therefore, here, the time T = T1 + T2 is set as the provisional descent time T in consideration of the chattering time T2. However, the time Tb = T + Δt is set as the error determination reference value Tb in consideration of the error for each drop. Then, during the game, the descent time of the movable accessory 140 is calculated from the time difference between the descent start timing of the movable accessory 140 where the electric motor 232 has rotated several steps from the detection timing by the photosensor 246 and the detection timing by the photosensor 240. Then, error processing is performed when the descent time exceeds the error determination reference value Tb. The accessory control means 136 causes the effect display control means 134 to display a message indicating control abnormality on the effect display device 60. At this time, the error information may be notified by voice through the speaker 18 at the same time.
  In this embodiment, it is determined that chattering has converged when the OFF time when the signal waveform of the photosensor 240 changes from ON to OFF for a predetermined time longer than the chattering period, and the provisional descent time T is calculated. The temporary descent time T is calculated by trying the descent of the movable accessory 140 several times after turning on the power to the pachinko gaming machine 10 and obtaining the average value. Then, the error determination reference value Tb is set by adding the error time Δt to the provisional descent time T.
FIG. 6 is a flowchart showing a basic operation process in the pachinko gaming machine.
First, processing is performed when the game ball has won the start port 62, the general winning port 72, the big winning port 66, or when the game ball has passed through the operation port 68 (S10). (N in S12), control processing for normal games such as winning / failing lottery is executed (S14), and if a special game is in progress (Y in S12), control processing for special game is executed (S16), from S10 to S16 In step S18, prize ball payout corresponding to various winnings is processed.
  FIG. 7 is a flowchart showing in detail the normal game control process of S14 in FIG. In the normal game control process, if the winning / losing lottery value is on hold (Y in S30) and the symbol variation is not being displayed (N in S32), the winning / losing lottery means 112 executes the determining process. (S34). In accordance with the determination result, the main display control means 118 starts changing display, transmits a change start command to the effect display control means 134, and the effect display control means 134 that receives the command displays the effect image according to the change pattern data. The fluctuation display is started (S36). If the winning or failing lottery value is not held in S30 (N in S30), the processing from S32 to S36 is skipped, and if the symbol variation is being displayed in S32 (Y in S32), S34 and S36 Is skipped. Subsequently, if the symbol variation display has already started (Y in S38), the symbol variation display process is executed (S40). If the symbol variation display has not started (N in S38), S40 is skipped. . Subsequently, a control process for the movable accessory 140 is executed (S42).
FIG. 8 is a flowchart showing in detail the success / failure determination process of S34 in FIG.
First, the success / failure lottery means 112 reads the success / failure lottery value (S42), and determines the success / failure based on the success / failure lottery value (S44). The symbol determining means 114 determines a stop symbol of the special symbol based on the determination result (S46), and selects a variation pattern of the special symbol (S48). The effect determination means 132 determines the stop symbol combination of the decorative symbols based on the determination result and the special symbol (S50), and selects the variation pattern of the decorative symbol according to the variation pattern of the special symbol (S52).
  FIG. 9 is a flowchart showing in detail the movable accessory control process of S42 in FIG. The accessory control means 136 first sets the error determination reference value Tb described above after the pachinko gaming machine 10 is powered on. That is, if the error determination reference value Tb has not yet been set (N in S102), the drive gear 226 is driven for the setting, and the movable accessory 140 is raised to the top dead center position and lowered on a trial basis. (S103). Then, the provisional descent time T is measured (S104), and the number of trials is counted using a counter (not shown).
  At this time, if the number of trials does not reach the set number (for example, 3 times) (N in S106), the process is temporarily exited. If the number of trials has reached the set number in S106 (Y in S106), the average value of the provisional descent time T described above is calculated (S108), and a predetermined error time Δt is added to this to determine an error criterion. A value Tb is set (S110). The error determination reference value Tb is stored in a RAM or the like and used for subsequent control processing of the movable accessory 140.
  In S102, if the error determination reference value Tb has already been set (Y in S102), the movable accessory 140 is not being driven (N in S112), and the drive start timing is based on a predetermined program. (Y of S114), the drive control of the movable accessory 140 is started (S116). In this drive control, the movable accessory 140 is moved up and down to assist the effect displayed on the effect display device 60. For example, when the possibility of winning or failing the lottery increases, the movable accessory 140 is caused to perform a predetermined ascending / descending operation, but the specific performance operation is omitted. On the other hand, if the movable accessory 140 is already being driven in S112, the processes in S114 and S116 are skipped. If the drive start timing is not reached in S114 (N in S114), the process is temporarily terminated.
  When the descent is started in the drive control of the movable accessory 140 (Y in S118), the descent time is calculated (S120). That is, the accessory control means 136 determines the start of the descent of the movable accessory 140 when the electric motor 232 is rotated several steps after the photosensor 246 is turned on. Then, the time from when the movable accessory 140 starts to descend until the above chattering converges, that is, until the OFF state of the photosensor 240 is stabilized, is calculated as the descent time. At this time, if the descent time exceeds the error determination reference value Tb (Y in S122), the operation is stopped because the control state of the movable accessory 140 is abnormal, and an error message is displayed on the effect display device 60. (S126). If the descent time does not exceed the error determination reference value Tb in S122 (N in S122), the drive control started in S116 is continued. The error determination reference value Tb set in S110 disappears from the RAM when the power of the pachinko gaming machine 10 is cut off, so that a new error determination reference value Tb is set at the next power supply introduction. For this reason, in a normal pachinko hall, an error determination reference value Tb is set at the time of opening a store, and one day business is performed using the reference value.
FIG. 10 is a flowchart showing in detail S16 in FIG.
First, if the big prize opening 66 has not been opened (N in S70), the production display control means 134 starts the special game production process (S72), and the open / close control means 124 opens the special prize opening 66 (S74). ). If the big winning opening 66 has been opened, S72 and S74 are skipped (Y in S70). When the predetermined opening time has elapsed since the grand prize opening 66 was opened (Y in S76), or the opening time has not elapsed (N in S76), there are nine or more game balls to the big winning opening 66 When the player has entered the ball (Y in S78), the opening / closing control means 124 closes the special winning opening 66 (S80). If the opening time has not elapsed (N in S76) and the number of balls entered into the grand prize winning opening 66 has not reached nine or more (N in S78), the processing after S80 is skipped and the flow of S16 Exit.
  If the number of rounds of the unit game has reached 15 after closing the special winning opening 66 in S80 (Y in S82), the effect display control means 134 ends the effect processing of the special game (S84), and the special game control means 120 ends the special game (S86). If the number of rounds has not reached 15 (N in S82), 1 is added to the number of rounds and the flow of S16 is terminated (S90).
  As described above, in the pachinko gaming machine 10 according to the present embodiment, the error determination reference value Tb is set for the descent time of the movable accessory 140, and an error for confirming the operation abnormality of the movable accessory 140 based on this is determined. A determination is made. Since an error notification is performed when there is an abnormality in the operation of the movable accessory 140, appropriate measures can be taken thereafter. On the other hand, since the error determination reference value Tb is updated every time the power is turned on, even if the movable accessory 140 or its elevating mechanism 204 changes over time, it is updated to a reference value reflecting the change over time. Even if there is a mismatch with the control amount from the beginning due to individual differences of the movable accessory 140 or the like, an error determination reference value Tb suitable for the movable accessory 140 is set after the power is turned on. For this reason, as long as the movable accessory 140 and the like are normal, the consistency between the control amount and its operation can be kept long.
  In the above, this invention was demonstrated based on the Example. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are within the scope of the present invention. is there.
  In the above embodiment, an example in which the ball game machine of the present invention is configured as a so-called first type pachinko game machine has been shown. However, the conventional so-called second type pachinko game machine has an effect of lowering a movable accessory. The present invention can be applied as long as it is performed. In the above embodiment, the effect by the movable accessory 140 is positioned as assisting the effect display of the effect display device 60, but the effect of the movable accessory itself may be the main effect.
  In the above embodiment, the movable accessory 140 is suspended by a pair of left and right wires, and each wire is wound up by individual hoisting gears. However, the number of wires and hoisting gears is not limited thereto. A pair of or more wires may be wound up by one hoisting gear, or the movable accessory may be suspended by one wire. Moreover, you may use wires other than a wire, such as a thread material which has a certain amount of strength and durability.
  In the above-described embodiment, the configuration in which the movable accessory 140 is lowered in a manner close to free fall has been shown. However, for example, even if the movable accessory is lowered so as to slide along a guide having a predetermined inclination angle. Good. Further, instead of a configuration in which the movable accessory is suspended, a configuration in which the movable accessory is lifted and lowered by a predetermined link mechanism, a rack and pinion mechanism, or the like may be used. Any configuration may be used as long as the movable accessory is raised by the operation of the mechanism, the support state is released at a certain position, and the movable accessory is lowered by its own weight.
  In the above embodiment, an example in which the photosensor 246 detects the missing tooth portion 230 itself of the drive gear 226 is shown. In the modification, a portion that transmits or shields light may be provided in the vicinity of the toothless portion 230 of the hoisting gear 224, and the descent start timing of the movable accessory 140 may be determined by detecting this portion. .
  In the above embodiment, the photo sensor 246 is arranged not in the meshing position itself between the hoisting gear 224 and the drive gear 226, and it is detected that the meshing position of both gears has reached a predetermined position in the vicinity of the missing tooth portion. The configuration is shown. In other words, the photosensor 246 detects the timing slightly before the start of the descent of the movable accessory 140, and the time when the electric motor 232 rotates several steps therefrom is calculated as the descent start timing of the movable accessory 140.
