Abstract

PROBLEM TO BE SOLVED: To prevent a backlash between gears when force different from drive force acts on the gears.SOLUTION: A gear mechanism 240 may take an advancing state (a) to transmit the power of a drive gear 901 to a Yakumono (accessory) gear 903, or a non-advancing state (b) in which neither the drive gear 901 nor the Yakumono gear 903 acts on each other, as a rotation state when the drive gear 901 rotates in one rotation direction with a prescribed gap α. A lamp control part controls the drive gear 901 based on the motion of a movable Yakumono on which the advancing force acts to put the gear mechanism 240 in a prescribed gear state (the advancing state or non-advancing state) when working force (e.g., advancing force) different from the rotation force of the drive gear 901 works on the movable Yakumono.

Description

  The present invention relates to a gaming machine that produces an effect using a movable accessory provided so as to be movable with respect to a game board.

  Conventionally, when a game ball launched into the game area of the game board wins a specific starting port, whether or not the random number acquired at the timing of starting winning matches with a predetermined jackpot random number is controlled by the main control unit Pachinko machines that make a hit determination are widely used. As a result of the hit determination, when it is determined that the game is a jackpot, the special symbol is stopped at the symbol indicating the jackpot, and the game is shifted to a jackpot game state that is a game state advantageous to the player. When the hit determination is performed, the variation mode indicating the variation time of the special symbol is also determined.

  The pachinko gaming machine is provided with an effect control unit that performs an effect using an image display unit or the like in response to a hit determination or a variation mode determination result by the main control unit. The production control unit performs reach production when a predetermined special symbol changes. The reach effect is, for example, when three decorative symbols (first decorative symbol, second decorative symbol, third decorative symbol) are changed, the first decorative symbol and the second decorative symbol are related to the active line. After arranging in the same design (for example, the same design), only the third decorative design is changed, the production time is longer than usual, and the expectation for jackpot is increased.

  In the case of a big hit, the effect control unit stops the third decorative symbol with a decorative symbol related to the first decorative symbol and the second decorative symbol. On the other hand, in the case of a loss, the third decorative symbol is stopped with a decorative symbol that is not related to the first decorative symbol and the second decorative symbol.

  In addition to reach production, pachinko machines perform various productions in order to increase the player's expectation and entertain the player before showing the lottery result of the jackpot lottery. For example, in addition to a notice effect that suggests a reach effect using an image display unit, a lamp effect such as blinking or lighting using multiple lamps, a so-called gimmick (movable accessory) is turned on. A thing that performs an effect production by moving or operating is also used (for example, refer to Patent Document 1 below). The movable combination is connected to a drive motor, and is movable between a retracted position where the movable combination is retracted by driving rotation of the drive motor and an advanced position where the movable combination has advanced.

  In recent pachinko gaming machines, the mechanical action using a movable accessory has a great impact on the player and plays an important role in production. For example, an effect using a movable accessory is an effect that is performed as a precursor to a big hit, in other words, it is one of highly reliable effects.

  In recent pachinko gaming machines, a movable accessory is operated in a complicated manner in a limited space due to an increase in the size of an image display unit or the like. When the movable accessory is moved from the retracted position to the advanced position, a force different from the driving force may act on the movable accessory. Specifically, if the movable accessory is moved along the guide rail provided with the inclined portion, a force that prevents movement in the advancing direction acts at the entrance of the inclined portion, or advances due to gravity at the inclined portion. A force that promotes movement in the direction acts.

  Further, in the case where the urging spring is attached to the movable accessory, the force that prevents the movement in the advancing direction acts due to the extension of the urging spring. Examples of the urging spring include a spring for preventing deflection of a signal line for lighting a lamp included in the movable accessory, and a spring for restricting the operation of the movable accessory.

JP 2007-319374 A

  However, the above-described conventional technique has a problem that a phenomenon called so-called backlash occurs in which the gear is reversed or the drive transmission is not performed properly due to the action of a force different from the drive force. . With respect to this, a case will be described in which the slope of the downhill is moved after the movable accessory is moved horizontally using the relationship of each gear. FIG. 22 is an explanatory diagram showing the relationship between the drive gear and the accessory gear. In FIG. 22, the description will be made using two gears for convenience of explanation, but actually, it is constituted by a large number of gears.

  In FIG. 22, (a) has shown the state at the time of a movable accessory moving a horizontal part. When the movable accessory is moved in the horizontal direction, the rotational force of the drive motor is transmitted to the movable accessory. Specifically, as shown in (a), the drive side state is such that the rotational force V of the drive gear 2201 (drive motor) is transmitted to the accessory gear. In general, the gears need moderate play from the viewpoint of preventing the gears from getting stuck and moving, and also between the drive gear 2201 and the accessory gear 2202 shown in FIG. A predetermined gap α corresponding to play is provided.

  (B) has shown the state at the time of a movable accessory moving the inclination part of a downhill. Specifically, in the inclined portion, the movable accessory moves faster due to gravity (self-weight) as a force different from the driving force, whereby the accessory gear 2202 rotates faster than the driving gear 2201. At this time, as shown in (b), the drive gear 2201 may not follow the accessory gear 2202 and may have a retracting side engagement in which a force W in a direction that hinders the operation of the accessory gear 2202 acts. As described above, when the transmission direction of the force between the drive gear 2201 and the accessory gear 2202 changes during the advancement operation of the movable accessory, the gear reverses or the driving force of the drive gear 2201 is applied to the accessory gear 2202. Backlash may occur, which may not be transmitted well.

  Further, the backlash occurs not only when the accessory gear 2202 rotates faster than the drive gear 2201 but also when, for example, a force in a direction that hinders the advancement operation of the accessory is generated by the biasing spring. Specifically, it is assumed that the movable accessory is dropped and moved at high speed. Immediately after starting the advance operation, the drive motor is rotated in accordance with the moving speed of the movable accessory. Specifically, it is assumed that the advancing operation is started in a non-operation state in which the driving gear 2201 does not interfere with the accessory gear 2202.

  If the urging force in the retracting direction is applied to the accessory gear 2202 during the advancing operation, the accessory gear 2202 changes to a meshing state in which the driving gear 2201 rotates in the retracting direction, and the driving gear 2201 Will be suddenly loaded. As a result, a backlash occurs in which the gear is reversed or the driving force of the driving gear 2201 is not transmitted well to the accessory gear 2202.

  An object of the present invention is to prevent backlash between the gears when a force different from the driving force is applied and to smoothly operate the accessory in order to solve the above-described problems caused by the prior art.

  In order to solve the above-described problems and achieve the object, the present invention employs the following configuration. Reference numerals in parentheses indicate correspondence with the embodiments in order to facilitate understanding of the present invention, and do not limit the scope of the present invention. The gaming machine (100) according to the present invention is a combination of effects for an effect (131), a driving gear (901) for driving and rotating, and the driving gear (901) and connected to the accessory (131).

A first gear state in which the power of the gear (901) is transmitted to the accessory gear (903) or a second gear state in which the drive gear (901) and the accessory gear (903) do not interact with each other is taken. Get too When the acting force different from the rotational force of the drive gear (901) acts on the accessory (131), the drive control means (1001) operates the accessory (131) on which the acting force acts. Based on the above, the drive gear (901) is controlled to bring the gear mechanism (240) into the predetermined gear state.

  In the above invention, the accessory (131) is movable between a general area and a special area that communicates with the general area and acts as a predetermined advance output. The drive control means (1001) In the general region, the gear mechanism (240) is set to the first gear state to drive and rotate the drive gear (901), while in the special region, based on the action of the accessory (131) by the predetermined advance output. The drive gear (901) is driven to rotate so that the gear mechanism (240) has a rotation speed at which the first gear state or the second gear state is achieved.

FIG. 6 is an explanatory diagram (part 2) illustrating the operation of the movable accessory. First, the retracted position, which is the initial position, is in the state shown in FIG. When the drive motor 211 is driven to rotate, the moving mechanism 200 (rack gear 301d) starts moving in the left direction in the figure.

  When the rack gear 301d moves leftward, the support plate 202 moves along the guide rail 220 (horizontal path 221), that is, moves with only the horizontal component. Furthermore, the rack gear 301d moves leftward, and the support plate 202 reaches the switching path 222, that is, moves with a horizontal component and a downward component.

  As shown in FIGS. 5B and 6A, when the support plate 202 moves with a downward component, the second gear mechanism 401 connected to the support plate 202 rotates and moves along the rack teeth 401a. Move down. Further, as the second gear mechanism 401 rotates and moves downward, the rotation support member 412 and the decorative body 201 connected to the second gear mechanism 401 also move downward while rotating. The decorative body 201 moves downward while rotating clockwise, for example.

  In other words, the switching path 222 requires a larger driving force than the horizontal path 221 due to switching of the moving direction of the movable accessory 131, starting of the operations of the first operating mechanism 300 and the second operating mechanism 400, and the like. When the vehicle passes through the switching path 222 and enters the steep ramp 223a, the movable accessory 131 moves by its own weight regardless of the driving force of the driving motor 211. At this time, the center of gravity J of the decorative body 201 moves with the rotational force due to the downward movement.

  Then, when entering the gentle ramp 223b as shown in FIG. 6A, the action of gravity (acceleration by its own weight) becomes weaker than the steep ramp 223a, and the center of gravity J of the decorative body 201 moves downward. Therefore, it moves by the driving force of the drive motor 211. Further, as shown in FIG. 6B, when the movable accessory 131 further moves forward and reaches the most advanced position, the rack gear 301d moves to the left, and the support plate 202 moves downward and rotates. The rotation of the support member 412 ends.

  When a predetermined time has elapsed at the advanced position, the drive motor 211 is reversed to return to the retracted position. At the time of retraction, by rotating the drive motor 211 in the direction opposite to that at the time of advancement, the movable accessory 131 performs an operation reverse to the operation at the time of advancement and returns to the retreat position. Specifically, the movable accessory 131 returns to the retracted position by performing the operations of FIG. 6 (b) → FIG. 6 (a) → FIG. 5 (b) → FIG. 5 (a). At this time, the decorative body 201 returns to the retracted position while rotating counterclockwise.

  Thus, in the present embodiment, the moving mechanism 200 that moves along the guide rail 220, and the first operating mechanism 300 that moves downward relative to the moving mechanism 200 in the movement having a component below the moving mechanism 200, The second operating mechanism 400 rotates with respect to the first operating mechanism 300 as the first operating mechanism 300 moves downward.

The display content of the display unit 113 is controlled. For example, when the first big hit lottery is performed, the main control unit 701 displays the first special symbol on the first special symbol display unit 112a in a variable manner. Then, after the predetermined period, the first special symbol is stopped and displayed with the symbol indicating the lottery result of the first big hit lottery.

For example, the RAM 753 includes a VRAM (Video RAM) in which image data representing an image to be displayed on the image display unit 104 is temporarily stored.

  That is, the image / sound control unit 702b causes the image display unit 104 to display on the basis of an instruction from the production control unit 702a by executing the program stored in the ROM 752 while the CPU 751 uses the RAM 753 as a work area. It functions to control images and sound output from the speaker 121.

  For example, the CPU 751 controls a display control process (not shown) for controlling the display content displayed on the image display unit 104 and the audio content output from the speaker 121 based on the instruction content instructed from the production control unit 702a. Voice control processing (not shown) is executed. At this time, the CPU 751 reads out image data and audio data necessary for processing from the ROM 752 and writes them in the RAM 753.

Specifically, by setting a layer in which images are stacked in a hierarchical structure, a decorative design is displayed so that it can be seen in front of the background image. For example, by setting a background image in a lower layer and setting a decorative design in a layer above it, the decorative design is displayed so that it can be seen in front of the background image. The layer setting is performed at the start of the change or at a predetermined layer setting timing during the change.

  The audio data written in the RAM 753 is output to the speaker 121 connected to the image / audio control unit 702b, and audio based on the audio data is output from the speaker 121.

(Control for drive motor at the time of advancement)
Next, control of the drive motor 211 when the movable accessory 131 advances will be described with reference to FIG. 8-1 is explanatory drawing which shows control with respect to the drive motor at the time of advancement of a movable accessory. Explanation of FIG. 8A FIG. 810 shows the motor rotation speed (pps) at each displacement of the movable accessory 131.

  Here, the torque and the motor rotation speed have a predetermined correlation, and specifically, are inversely proportional. In FIG. 8A, for convenience of explanation, the guide rail 220 is schematically illustrated corresponding to the displacement of the horizontal axis. In addition, the guide rail 220 shown in FIG. 8-1 has shown the state seen from the back side of the pachinko gaming machine 100.

  In the present embodiment, as shown in the explanatory diagram 810, when the movable accessory 131 is advanced by the moving mechanism 200, the drive motor 211 is rotated to some extent from immediately after the advance operation in order to move the linear horizontal path 221. Rotate at speed. When the movable accessory 131 is displaced by the moving mechanism 200, the movable accessory 131 reaches the switching path 222.

  In the switching path 222, unlike the horizontal path 221 and the inclined path 223 behind the switching path 222, a force that prevents movement in the advancing direction acts. Specifically, an extra force is applied when the movable accessory 131 abuts on the upper sliding wall 222a of the switching path 222 and presses the upper sliding wall 222a. In the switching path 222, a force for operating the movable accessory 131 by the first operating mechanism 300 and the second operating mechanism 400 also starts to be applied.

  Specifically, the switching path 222 is also a point at which the movement of the movable accessory 131 in the vertical direction is started when the first operation mechanism 300 operates. When the movement in the vertical direction is started, as shown in FIG. 5B and FIG. 6A, the operation of the second operation mechanism 400 (the rotation operation of the second gear mechanism 401) is performed. Thus, the decorative body 201 connected to the second gear mechanism 401 rotates.

  That is, in the switching path 222, not only the force that presses the upper sliding wall 222 a due to the movement of the movable accessory 131, but also the decorative body 201 is rotated by the second operating mechanism 400 and the decorative body 201 is rotated by the first operating mechanism 300. The force by moving down is also required. As described above, the switching path 222 requires extra force compared to the movement on the horizontal path 221.

  Therefore, in the present embodiment, in the switching path 222, the rotational speed of the drive motor 211 is increased or decreased based on a sine curve that is a relaxation curve. Specifically, the rotational speed is set to a rotational speed based on the moving speed (rotational force) in the horizontal path 221, that is, the rotational speed is reduced to a level that can maintain a smooth operation, thereby obtaining a large torque. That is, in the switching path 222 where a force that prevents the movable accessory 131 from moving in the advancing direction is applied, the rotational speed of the drive motor 211 based on the relaxation curve can be used to smoothly accelerate and decelerate the movable accessory 131. I have to.

  When the torque is represented as a graph, the graph in FIG. 8A is inverted with the horizontal axis as the axis of symmetry, and specifically, the graph is convex upward on the switching path 222. In this embodiment, the rotational speed is increased or decreased based on a sine curve as a relaxation curve, but is not limited to a sine curve. For example, the rotational speed is increased or decreased based on a clothoid curve in which the radius of the curve gradually decreases as the curve progresses. It is good.

  The curve shown in FIG. 810 uses a sine curve to increase / decrease the rotational speed in the region R other than the switching path 222, that is, the increase degree and the decrease degree are curves that approximate the sine curve. It has become. Although the rotation speed is decreased in the switching path 222, the rotation speed is not high enough for the player to visually recognize the deceleration because the movable accessory 131 operates at a high speed.

  When the vehicle enters the steep slope 223a past the switching path 222, the force that presses the upper sliding wall 222a due to the movement of the moving mechanism 200 is not applied. Moreover, since it is steep, the driving force in the advancing direction by gravity (self-weight) acts on the moving mechanism 200. Moreover, the rotational force by the center of gravity J of the decorative body 201 moving downward also acts as a propulsive force. That is, on the steep ramp 223a, the movable accessory 131 operates at a high speed regardless of the driving force of the driving motor 211.

  Therefore, so-called backlash may occur. Here, the backlash means that the moving direction of the force between the gears (gear mechanism 240) is changed and the gears are reversed when the movable accessory 131 operates faster than the drive motor 211. . Therefore, in the present embodiment, on the steep ramp 223a, the backlash is suppressed by rotating the drive motor 211 at a high speed in accordance with the high-speed movement of the movable accessory 131.

(Example of drive data)
Next, an example of drive data of the drive motor 211 used when the movable accessory 131 advances will be described with reference to FIG. 8-2 is explanatory drawing which shows an example of the drive data used at the time of advance of a movable accessory. The drive data 820 shown in FIG. 8-2 indicates the relationship between the number of steps (displacement) and the rotation speed (pulse). More specifically, for example, the first 50 steps rotate at 700 pps, the next 4 steps rotate at 670 pps, and the next 4 steps rotate at 671 pps.

  The drive data 820 is stored in the ROM 762 of the lamp control unit 702c. The drive data indicated by the symbol x indicates the data of the horizontal path 221 and the rotational speed is rapidly increased as the number of steps increases. The drive data indicated by symbol y indicates the data of the switching path 222 in FIG. That is, the rotational speed is reduced to obtain a large torque.

  In the switching path 222, a force for starting the downward movement of the movable accessory 131 (decorative body 201) while rotating is also necessary, and the drive data indicated by the symbol y is such force or switching path. The rotational speed in the horizontal path 221 immediately before reaching 222 is considered. Although the rotational speed is reduced, the deceleration is not so fast that the player can visually recognize the deceleration because the movable accessory 131 operates at a high speed. In other words, a decrease in the moving speed of the movable accessory 131 when reaching the switching path 222 from the horizontal path 221 is suppressed as much as possible while maintaining a rotational speed with a rotational force that allows the movable accessory 131 to pass through the switching path 222. It allows for smooth operation.

  Further, the drive data indicated by the symbol z indicates data of the ramp 223. Reference sign z1 indicates data of the steep ramp 223a. In the steep slope 223a, since a propulsive force (gravity and rotational force) acts on the movable accessory 131, this propulsive force is taken into consideration and becomes a value that accelerates faster than the other paths 221, 222, and 223b. Yes. Reference sign z2 indicates data of the gentle ramp 223b. In the gentle ramp 223b after passing through the steep ramp 223a, the rotational speed is increased as the number of steps is increased until the rotational speed reaches a constant rotational speed (2600pps), as in the drive data indicated by the symbol x. ing.

  With such drive data 820, while the acceleration is fast on the horizontal path 221 and the inclined path 223, the rotation speed of the drive motor 211 is decreased on the switching path 222 to smooth the operation when passing through the switching path 222. In addition, the rotational speed of the drive motor 211 is set in consideration of the high acceleration of the decorative body 201 on the steep ramp 223a. In other words, complex operations are performed at high speed. Therefore, the movable accessory 131 can be operated quickly while preventing backlash, and an effect with impact can be performed.

(Gear mechanism engagement)
Next, the meshing state of the gear mechanism 240 (the first gear mechanism 301 and the second gear mechanism 401) of the movable accessory 131 will be described with reference to FIGS. 9-1 and 9-2. 9-1 is explanatory drawing which shows the meshing state of a gear mechanism. In FIG. 9A, three gears (drive gear 901, intermediate gear 902, and accessory gear 903) are schematically shown and described for convenience of explanation. As shown, it is composed of a large number of gears.

  Specifically, the drive gear 901 corresponds to the drive gear 301a (see FIG. 3). The accessory gear 903 corresponds to the lower gear 401d (see FIG. 4) that is finally connected to the decorative body 201 (movable accessory 131). The intermediate gear 902 includes driven gears 301b and 301c, rack gear 301d, rack teeth 401a, upper gear 401b, and intermediate gear 401c interposed between the drive gear 301a and the lower gear 401d.

  In general, gears require moderate play from the viewpoint of preventing the gears from getting stuck and moving, and each gear 901 to 903 is provided with play. In FIG. 9A, this play is simplified as the gap α. The meshing state of the gear is switched by the gap α.

  FIG. 9A shows a state when the movable accessory 131 passes through the horizontal path 221, the switching path 222, and the gentle slope path 223b. In the horizontal path 221, the switching path 222, and the gentle slope path 223b, the driving force of the drive gear 901 (drive motor 211) is transmitted to the intermediate gear 902 and the accessory gear 903, whereby the movable accessory 131 operates. (A) is a state in which the driving gear 901 transmits driving force to the intermediate gear 902 and the accessory gear 903 (hereinafter referred to as “advance action state”), and corresponds to the first gear state of the present invention.

  On the steep ramp 223a, the movable accessory 131 is accelerated by the propulsive force. The propulsive force is the rotational force due to gravity (self-weight) or the center of gravity J (see FIG. 5) of the decorative body 201 moving downward. At this time, the drive gear 901 is also rotated in accordance with the acceleration of the movable accessory 131 so that the gears 901 to 903 are not caused to act as shown in FIG. The meshing state of each of the gears 901 to 903 shown in (b) is hereinafter referred to as “non-operating state” and corresponds to the second gear state of the present invention.

  In the non-actuated state, the gears do not act, but the drive gear 901 is in contact with the intermediate gear 902 and the accessory gear 903 from the direction in which a force can be exerted. That is, in the non-actuated state, the gap α is generated only on the side where the convex portions 911 to 913 of the gears 901 to 903 are not in contact with each other, as in the advancing action state shown in FIG. Yes.

  Thus, by rotating the drive gear 901 at a rotational speed in accordance with the acceleration of the movable accessory 131, a force in the direction of preventing the operation from the drive gear 901 to the accessory gear 903 does not act, and backlash is prevented. It can be deterred. When the movable accessory 131 passes through the steep ramp 223a and reaches the gentle ramp 223b, the gears 901 to 903 are in the advanced action state of (a).

  Further, in the steep slope 223a, the meshing state of each of the gears 901 to 903 is not limited to the non-operating state, so that the moving speed of the movable accessory 131 is faster, that is, the drive gear 901 is the intermediate gear 902 and It is good also as an advance action state which transmits a driving force to the accessory gear 903. FIG. Even if it is set as such a structure, the force of the direction which prevents operation | movement from the drive gear 901 to the accessory gear 903 does not act on the steep slope 223a, and backlash can be suppressed.

  In the present embodiment, the non-operating state is a state in which the driving gear 901 is in contact with the intermediate gear 902 and the accessory gear 903 from the direction in which force can be applied, as shown in FIG. Not limited to. Here, another example of the state when the movable accessory 131 passes the steep ramp 223a will be described with reference to FIG.

  9-2 is explanatory drawing which shows the other example of the meshing state of a gear mechanism. FIG. 9-2 shows a state when the movable accessory 131 passes through the steep ramp 223a. The gap α is generated on both sides (gap α1, α2) of the convex portions 911-913 of the gears 901-903. In the steep ramp 223a, as in FIG. 9B, in order to rotate the drive motor 211 at a speed equivalent to the moving speed of the movable accessory 131, the drive gear 901, the intermediate gear 902, and the accessory gear 903 are respectively Rotate without interference (without action).

  In this case, in order to shift each gear 901 to 903 more smoothly from the non-acting state to the advancing action state, that is, when shifting from the non-acting state to the advancing action state, an impact associated with switching of the meshing state by the gap α. In order to further suppress the above, it is desirable to make the gap α1 smaller than the gap α2.

  In other words, in the non-actuated state, it is desirable that the engagement state is closer to the advance action state than the accessory-driven state (a state in which power is transmitted from the accessory gear 903 to the drive gear 901). Note that the transition from the non-action state to the advancement action state occurs when the movable accessory 131 reaches the gentle ramp 223b from the steep ramp 223a.

  Most preferably, as shown in FIG. 9-1 (b), the drive gear 901 is in contact with the intermediate gear 902 and the accessory gear 903 from a direction in which a force can be applied. If it does in this way, it can be in the state which contacted each gear 901-903 similarly to the advance action state in a non-action state, and when shifting from a non-action state to an advance action state, it is in the meshing state by gap alpha. The impact associated with switching can be minimized. Thereby, backlash can be suppressed most effectively.

(Functional configuration of the present embodiment)
Next, the functional configuration of the present embodiment will be described with reference to FIG. FIG. 10 is a block diagram showing a functional configuration of the present embodiment. In FIG. 10, the lamp control unit 702 c includes a drive control unit 1001 and a storage unit 1002.

  First, the drive motor 211 and the gear mechanism 240 according to the present embodiment will be supplemented. The drive motor 211 is connected to the movable accessory 131, and is driven to rotate with a predetermined correlation between the rotational speed and the rotational force (torque). Specifically, the predetermined correlation is an inversely proportional relationship, and generally, the motor output that is the capability of the drive motor 211 can be represented by the product of the rotation speed and the torque.

  As illustrated in FIG. 9A, the gear mechanism 240 includes a plurality of gears 901 including a driving gear 901 that is driven and rotated, and an accessory gear 903 that is connected to the driving gear 901 and connected to the movable accessory 131. 903. Further, the gear mechanism 240 has a predetermined gap α between the plurality of gears 901 to 903.

  As shown in FIG. 9A, the gear mechanism 240 transmits the power of the drive gear 901 to the accessory gear 903 as a rotation state when the drive gear 901 rotates in one rotation direction by a predetermined gap α. In the first gear state ("advance action state" in FIG. 9-1 (a)) or the second gear state in which the drive gear 901 and the accessory gear 903 do not interact with each other ("" in FIG. 9-1 (b) " Inactive state)). The gear mechanism 240 can also take a third state (an accessory-driven state) in which power is transmitted from the accessory gear 903 to the drive gear 901 by a predetermined gap α.

  The drive control unit 1001 drives and rotates the drive motor 211 using the drive data stored in the storage unit 1002. The drive data is, for example, as shown in FIG. When an acting force different from the rotational force of the drive gear 901 acts on the movable accessory 131, the drive control unit 1001 controls the drive gear 901 based on the operation of the movable accessory 131 on which the acting force acts, thereby causing a gear mechanism. 240 is brought into a predetermined gear state.

  In the present embodiment, the acting force is a force that promotes the rotation of the drive gear 901 in the steep ramp 223a. Specifically, it is the rotational force (moment) generated by the gravity (self-weight) and the center of gravity J (see FIG. 2) moving downward. In the present embodiment, the drive control unit 1001 controls the drive gear 901 (drive motor 211) to control the gear mechanism 240 based on the operation of the movable accessory 131 (acceleration of the accessory gear 903) on the steep slope 223a. A predetermined gear state (non-operation state) is set.

  The acting force is not limited to the force in the direction of promoting the rotation of the drive gear 901, and may be a force that prevents the drive gear 901 from rotating. Examples of the force that hinders the rotation of the drive gear 901 include an urging force by an urging spring or the like. The specific configuration using the urging spring includes a configuration using a signal line spring that prevents deflection of the signal line connected to the movable accessory 131 and a restriction for preventing the movable accessory 131 from dropping at the retracted position. This is a configuration using a spring.

  In the configuration using the urging spring, when the movable accessory 131 is dropped and moved, the urging force in the direction opposite to the advancing direction of the movable accessory 131 acts on the movable accessory 131 by the urging spring, and a predetermined position during the advancing This adversely affects the operation of the movable accessory 131. Specifically, when the drive motor 211 (drive gear 901) is rotated following the fall of the movable accessory 131 (the accessory gear 903) at the start of advance movement, that is, the engagement state is set to the accessory-driven state. Then, since the rotational speed of the accessory gear 903 is weakened at the predetermined position, the meshing state is suddenly switched to the advancing action state, which may cause backlash.

  In such a configuration, the drive control unit 1001 controls the drive gear 901 (the drive motor 211) based on the operation of the movable accessory 131 at the predetermined position (acceleration of the accessory gear 903), and the gear mechanism 240. To a predetermined gear state (advancing action state). In this case, before the predetermined position, the non-operating state or the advancement action state is set so that the meshing state does not rapidly change from the accessory-driven state to the advancement action state.

  Further, in the present embodiment, the movable accessory 131 is movable between a general area and a special area that communicates with the general area and has a predetermined advance output. The general areas are the horizontal path 221, the switching path 222, and the gentle ramp 223b. The special area is the steep ramp 223a. The predetermined advance output is the gravity (self-weight) that works due to the steep slope of the steep ramp 223a or the rotational force (moment) by the center of gravity J.

  The drive control unit 1001 drives and rotates the drive gear 901 with the gear mechanism 240 in the advanced action state in the general region. On the other hand, on the steep ramp 223a, the drive control unit 1001 makes the rotation speed at which the gear mechanism 240 is in the advanced action state or the non-action state based on the operation (acceleration) of the movable accessory 131 by the predetermined advance output. The drive gear 901 is driven to rotate.

  The drive control unit 1001 is realized by the CPU 761 of the lamp control unit 702c. That is, the CPU 761 executes the various programs stored in the ROM 762, thereby realizing the function of the drive control unit 1001. The storage unit 1002 is realized by the ROM 761 of the lamp control unit 703c.

(1. Processing performed by the main control unit)
Next, an example of detailed processing performed by the pachinko gaming machine 100 to realize the above-described operation will be described. First, processing performed by the main control unit 701 of the pachinko gaming machine 100 will be described. Note that each process of the main control unit 701 described below is performed by the CPU 711 of the main control unit 701 executing a program stored in the ROM 712, for example.

(Main timer interrupt processing)
FIG. 11 is a flowchart showing the contents of the main timer interrupt process. When the supply of power is started, the main control unit 701 starts execution of a main control process (not shown) including a startup process and a power-off monitoring process. The main control unit 701 continuously executes this main control process while power is supplied. The main control unit 701 interrupts and executes a main timer interrupt process at a predetermined period (for example, 4 ms) with respect to the main control process.

  As shown in FIG. 11, in the main timer interrupt process, the main control unit 701 first executes a random number update process for updating random numbers used in various lotteries performed by the main control unit 701 (step S1101). In this random number update process, the main control unit 701 updates a winning random number, a design random number, a variation pattern random number, and the like.

  Next, the main control unit 701 executes switch processing for detecting with various switches (step S1102). In this switch process, the main control unit 701 starts the start port switch process (see FIG. 12) for detecting a game ball won in the start port (first start port 105, second start port 106), and the game that has passed through the gate 108. Gate switch processing for detecting a ball (detailed explanation and illustration are omitted), big winning opening switch processing for detecting a game ball won in the big winning opening 109 (detailed explanation and illustration are omitted), and winning a normal winning opening 110 A normal winning a prize opening switch process (detailed explanation and illustration are omitted) for detecting the played game ball is performed.

  Subsequently, the main control unit 701 executes symbol processing relating to special symbols and normal symbols (step S1103). Here, the symbol process includes a special symbol process related to the special symbol (see FIG. 13) and a normal symbol process related to the normal symbol (detailed description and illustration are omitted). In the special symbol process, the main control unit 701 performs a jackpot lottery to perform display control of the special symbol. In the normal symbol process, the main control unit 701 performs a normal symbol lottery to perform display control of the normal symbol.

  Subsequently, the main control unit 701 executes an electric accessory control process related to the operation control of the special winning opening 109 and the electric tulip 107 (step S1104). Here, the electric accessory control process includes an extra prize opening process (detailed explanation and illustration is omitted) for controlling the operation of the extra prize opening 109 and an electric tulip process (detailed explanation and (Illustration is omitted). In the big prize opening process, the main control unit 701 controls the operation of the big prize opening 109 based on the lottery result of the big hit lottery. In the electric tulip process, the main control unit 701 controls the operation of the electric tulip 107 based on the lottery result of the normal symbol lottery.

  Subsequently, the main control unit 701 executes prize ball processing relating to prize ball payout control (step S1105). In the prize ball processing, the main control unit 701 gives a prize ball command to instruct the prize ball control unit 703 to pay out a predetermined number of prize balls when a game ball is won in the big prize opening 109 or the regular prize opening 110. This is set in the RAM 713 of the main control unit 701.

  Subsequently, the main control unit 701 executes an output process for outputting commands set in the RAM 713 to the prize ball control unit 703, the effect control unit 702, and the like by the processes of steps S1101 to S1105 (step S1106). The main timer interrupt process ends. When the main timer interrupt process ends, the main control unit 701 returns to the main control process.

(Start-up switch processing)
Next, the start port switch process included in the switch process of the main timer interrupt process (see step S1102 in FIG. 11) will be described with reference to FIG. FIG. 12 is a flowchart showing the processing contents of the start port switch processing. In the start port switch process, the main control unit 701 first determines whether or not the first start port SW721 is turned on (step S1201). If the first start port SW721 is not ON (step S1201: No), the process proceeds to step S1206.

  If the first start port SW721 is ON (step S1201: Yes), the main control unit 701 determines that the first special figure holding information number U1 acquired for the game ball won at the first start port 105 is It is determined whether it is less than 4 (U1 <4) (step S1202). If the number of first special figure hold information U1 is not less than 4 (step S1202: No), that is, if the number of first special figure hold information U1 is 4 or more, the process proceeds to step S1206.

  If the number of first special figure hold information U1 is less than 4 (step S1202: Yes), the main control unit 701 sets a value obtained by adding “1” to the number of first special figure hold information U1 to the new first special figure hold information U1. The value of the figure hold information number U1 is set (step S1203). Then, various random numbers such as winning random numbers are acquired as special figure hold information, and stored in the RAM 713 (step S1204).

  Thereafter, a preliminary determination process is performed based on the stored special figure hold information (step S1205). The prior determination process is a process for performing a hit determination, a variation pattern determination, or the like in advance before starting the variation of the special symbol. When the prior determination process is performed, the main control unit 701 subsequently determines whether the second start port SW722 is turned on (step S1206). If the second start port SW722 is not ON (step S1206: No), the start port switch process is terminated as it is.

  If the second start port SW722 is ON (step S1206: Yes), the main control unit 701 determines that the second special figure holding information number U2 acquired for the game ball won at the second start port 106 is It is determined whether it is less than 4 (U2 <4) (step S1207). If the number of second special figure reservation information U2 is not less than 4 (step S1207: No), that is, if the number of second special figure reservation information U2 is four or more, the start port switch process is terminated.

  If the number of second special figure hold information U2 is less than 4 (step S1207: Yes), the main control unit 701 sets a value obtained by adding “1” to the number of second special figure hold information U2 as a new second special figure. It is set as the value of the figure hold information number U2 (step S1208). Then, various random numbers such as winning random numbers are acquired as special figure hold information and stored in the RAM 713 (step S1209). Thereafter, a preliminary determination process is performed based on the stored special figure hold information (step S1210), and the start port switch process is terminated.

(Special symbol processing)
Next, a special symbol process included in the symbol process (see step S1103 in FIG. 11) of the main timer interrupt process will be described with reference to FIG. FIG. 13 is a flowchart showing the processing contents of the special symbol processing. In the special symbol process, the main control unit 701 determines whether or not the jackpot game flag indicating ON is in the jackpot game state is set to ON (step S1301). If the jackpot game flag is set to ON (step S1301: Yes), that is, if it is a jackpot game state, the special symbol process is terminated.

  If the jackpot game flag is set to OFF (step S1301: No), it is determined whether the special symbol is changing (step S1302). If the special symbol is changing (step S1302: Yes), the process proceeds to step S1311. If the special symbol is not fluctuating (step S1302: No), it is determined whether the second special figure holding information number U2 acquired for the game ball won in the second starting port 106 is 1 or more (step) S1303).

  If the number of second special figure hold information U2 is 1 or more (U2 ≧ 1) (step S1303: Yes), a value obtained by subtracting “1” from the number of second special figure hold information U2 is a new second special figure. The value of the hold information count U2 is set (step S1304), and the process proceeds to step S1307. If the number of second special figure hold information U2 is not 1 or more (step S1303: No), the number of first special figure hold information U1 acquired for the game ball won in the first start port 105 is 1 or more. Is determined (step S1305).

  If the number of first special figure hold information U1 is 1 or more (U1 ≧ 1) (step S1305: Yes), a value obtained by subtracting “1” from the number of first special figure hold information U1 is a new first special figure. The value of the hold information number U1 is set (step S1306), and the process proceeds to step S1307. If the number of first special figure holding information U1 is not 1 or more (step S1305: No), the special symbol process is terminated.

  Subsequently, the main control unit 701 performs a jackpot lottery process to derive a lottery result of the jackpot lottery (step S1307). Further, a special map fluctuation pattern determination process is performed to derive a determination result of the special map fluctuation pattern determination (step S1308). Then, based on the processing results of step S1307 and step S1308, the special symbol display unit 112 is started to display the variation of the special symbol (step S1309).

  When the special symbol is varied in step S1309, if the big hit lottery is performed for the game ball won in the second starting port 106 in step S1307, the second special symbol of the second special symbol display unit 112b is varied. If the big hit lottery is performed for the game ball won in the first starting port 105 in step S1308, the first special symbol of the first special symbol display unit 112a is changed.

  Subsequently, the main control unit 701 sets a change start command in the RAM 713 (step S1310). Here, the set change start command is, for example, a command including information indicating the lottery result of the jackpot lottery performed in step S1307 and the determination result of the special figure variation pattern determination performed in step S1308. When executing the output process (step S1106 in FIG. 11), the main control unit 701 outputs this change start command to the production control unit 702a.

  Subsequently, the main control unit 701 determines whether or not a period determined by the variation time has elapsed since the start of the variation of the special symbol (step S1311). In step S1311, it is determined whether a period corresponding to the variation time determined by the special figure variation pattern determined at the start of variation has elapsed. If the fluctuation time has not elapsed (step S1311: No), the special symbol process is terminated.

  If the fluctuation time has elapsed (step S1311: Yes), the main control unit 701 stops the special symbol so as to indicate the lottery result of the jackpot lottery performed at the start of the fluctuation (step S1312), and issues a fluctuation stop command. It is set in the RAM 713 (step S1313).

  Here, the set change stop command can be, for example, a command including information indicating the lottery result of the big hit lottery performed at the start of the change or the determination result of the special figure change pattern determination. When executing the output process (step S1106 in FIG. 11), the main control unit 701 outputs this change stop command to the effect supervision unit 702a. Then, a stop process for changing the gaming state based on the remaining number of times in the short-time gaming state and the remaining number of times in the high probability gaming state is executed (step S1314), and the special symbol processing is terminated.

(2. Processing performed by the Director of Production)
Next, the process performed by the effect control unit 702 will be described in detail. First, the processing performed by the production control unit 702a of the production control unit 702 will be described. In addition, each process which the production | presentation control part 702a demonstrated below performs, for example, when CPU741 of the production | presentation control part 702a executes the program memorize | stored in ROM742.

(Production timer interrupt processing)
FIG. 14 is a flowchart showing the contents of the effect timer interruption process. The production control unit 702a continuously performs production main processing (not shown) during activation, and the production timer interrupt processing shown in FIG. 14 is performed at a predetermined cycle (for example, 4 ms) for this production main processing. Interrupt execution.

  In the effect timer interruption process, the effect control unit 702a first performs a command reception process (see FIG. 15) (step S1401). After performing the command reception process, a part effect rendering process (see FIG. 17) for controlling the operation of the movable part 131 is performed (step S1402). Subsequently, an operation reception process for setting an operation command when an operation from the player is received by the effect button 119 or the cursor key 120 is performed (step S1403).

  Thereafter, command output processing is performed (step S1404). In the command output process, a process of outputting a command set in the RAM 743 to the lamp control unit 702c or the image / sound control unit 702b by a command reception process, an operation reception process, or a movable accessory effect process is performed.

(Command reception processing)
Next, the command reception process shown in step S1401 of FIG. 14 will be described with reference to FIG. FIG. 15 is a flowchart showing the processing contents of the command reception processing. In the command reception process, the production control unit 702a determines whether a change start command has been received from the main control unit 701 (step S1501). The variation start command is a command set in the special symbol process of the main control unit 701 (see step S1310 in FIG. 13). If the change start command has not been received (step S1501: No), the process proceeds to step S1504.

  If the change start command has been received (step S1501: Yes), the production supervision unit 702a performs an effect determination process for determining the content of the effect to be executed (step S1502). In the effect determination process, an effect is selected using a variable effect pattern selection table described later with reference to FIG.

  Then, a change production start command is set in the RAM 743 (step S1503). Thereafter, it is determined whether a change stop command has been received from the main control unit 701 (step S1504). The change stop command is a command set in the special symbol process of the main control unit 701 (see step S1313 in FIG. 13).

  If the fluctuation stop command has not been received (step S1504: No), the command reception process is terminated as it is. If the change stop command has been received (step S1504: Yes), an effect ending process for ending the effect being executed and setting the effect mode is performed (step S1505). Then, the change effect end command is set in the RAM 743 (step S1506), and the command reception process is ended.

(Example of variation production pattern selection table)
Next, an example of the variable effect pattern selection table used in the effect determination process shown in step S1502 of FIG. 15 will be described with reference to FIG. FIG. 16 is an explanatory diagram showing an example of the variation effect pattern selection table. In FIG. 16, the variation effect pattern selection table 1600 associates the special figure variation pattern with the variation effect pattern. The contents of the effect are described for convenience of explanation. The command output timing is a timing at which a command for instructing switching of effects is output to the image / sound control unit 702b and the lamp control unit 702c.

  The special symbol variation pattern is a variation pattern of the special symbol selected in the special symbol variation pattern determination processing (see step S1308 in FIG. 13) in the special symbol processing. In the case of a loss, any one of the special figure fluctuation patterns Hp1 to Hp3 is selected in the special figure fluctuation pattern determination process.

  In the case of a big hit, any one of the special figure fluctuation patterns Hp4 and Hp5 is selected in the special figure fluctuation pattern determination process. For example, in the case of the special figure fluctuation pattern Hp1, the fluctuation effect pattern Ep1 which is a normal loss effect is selected. In the case of the variation effect pattern Ep1, the command indicating the effect contents is output only at the timing t0 that is the variation start timing.

  Further, for example, in the case of the special figure fluctuation pattern Hp3 or the special figure fluctuation pattern Hp4, the effect of super reach (described as “SP” in the figure) 1 (the fluctuation effect pattern Ep3 or the fluctuation effect pattern Ep4) is performed. In the case of the variation effect pattern Ep4, an effect using the movable accessory 131 is performed together with the super reach 1. The effect using the movable accessory 131 is an effect indicating the jackpot confirmation called a so-called “determined accessory”.

  In the case of the variation effect pattern Ep4, a command indicating the effect contents is output at a timing t0 which is a variation start timing, a timing t11 which is a timing at which the movable accessory 131 is operated, and a timing t12 at which the movable accessory 131 is retracted. But it is output. By outputting commands to the image / sound control unit 702b and the lamp control unit 702c at timings t11 and t12, it is possible to produce an effect in which the image / sound control unit 702b and the lamp control unit 702c are synchronized.

  Similarly, for example, in the case of the special figure variation pattern Hp5, the variation effect pattern Ep5 that is a jackpot finalizing effect using the movable accessory 131 of the super reach 2 is selected. In the case of the variation effect pattern Ep5, a command indicating the effect contents is output at a timing t0 which is a variation start timing, a timing t21 which is a timing at which the movable accessory 131 is operated, and a timing t22 at which the movable accessory 131 is retracted. But it is output.

(Processing during the production of an accessory)
Next, with reference to FIG. 17, the process during effect production shown in step S1402 in FIG. 14 will be described. FIG. 17 is a flowchart showing the processing content of the processing during the effect production. In the processing during the effect production, the production supervision unit 702a determines whether or not the operation timing of the movable accessory 131 has come (step S1701). The operation timing of the movable accessory 131 is specifically the timing at which the movable accessory 131 is operated, and is the command output timing t11, t12, t21, t22 in FIG.

  If it is not the operation timing of the movable accessory 131 (step S1701: No), the process during the effect production is ended as it is. When it is the operation timing of the movable accessory 131 (step S1701: Yes), an operation command for operating the movable accessory 131 is set in the RAM 743 (step S1702), and the processing during the effect rendering is ended.

(3. Processing performed by the lamp controller)
Next, processing performed by the lamp control unit 702c will be described in detail. In addition, each process which the lamp control part 702c demonstrated below performs is performed when CPU761 of the lamp control part 702c runs the program memorize | stored in ROM762, for example.

(Ramp control processing)
FIG. 18 is a flowchart showing the processing contents of the lamp control processing. The lamp control unit 702c determines whether or not a change production start command is received from the production control unit 702a (step S1801). The variation production start command is a command set in the command reception process performed by the production supervision unit 702a (see step S1503 in FIG. 15). When the change production start command is not received (step S1801: No), the process proceeds to step S1804.

  When the change effect start command is received (step S1801: Yes), the change effect start command is analyzed (step S1802). Then, lighting data for lighting the panel lamp 122, the lamps of the movable accessory 131 and the decorative body 132, and the like are set in the RAM 763 (step S1803). Thereafter, it is determined whether or not an operation command has been received from the production control unit 702a (step S1804). The operation command is a command that is set in the process during the effect production performed by the production supervision unit 702a (see step S1702 in FIG. 17).

  When the operation command is not received (step S1804: No), the lamp control process is terminated as it is. When the operation command is received (step S1804: Yes), the operation command is analyzed (step S1805). Then, using the analysis result, drive data corresponding to the movable accessory 131 to be operated is set in the RAM 763 (step S1806), and the lamp control process is terminated.

  Here, when the movable combination 131 is operated as a result of the analysis of the operation command in step S1805, drive data for operating the movable combination 131 is set in step S1806. Specifically, the drive data for operating the movable accessory 131 is the drive data 820 shown in FIG.

  As described above, in the present embodiment, when an acting force different from the rotational force of the drive gear 901 acts on the movable accessory 131, the driving is performed based on the rotational speed of the accessory gear 903 on which the acting force acts. The gear 901 is controlled to bring the gear mechanism 240 into a predetermined gear state. Therefore, backlash between the gears when a force different from the driving force acts can be prevented, and the movable accessory 131 can be operated smoothly.

  Specifically, in the present embodiment, the drive mechanism 901 is driven and rotated by setting the gear mechanism 240 in the advanced action state in the horizontal path 221 and the switching path 222 and the like, while the steep ramp 223a is a movable accessory with a predetermined advance output. Based on the operation (acceleration) 131, the drive gear 901 is driven to rotate such that the gear mechanism 240 has a rotational speed at which the gear mechanism 240 is in the advanced action state or inactive state. Therefore, even when the movable accessory 131 suddenly accelerates on the steep slope 223a, the drive gear 901 cannot follow the accessory gear 903, and backlash can be prevented.

  In the present embodiment, the switching path 222 before the steep ramp 223a also requires a force for the movable accessory 131 (decorative body 201) to start moving downward while rotating. The high torque is obtained. That is, on the switching path 222, the backlash is likely to occur due to the rapid acceleration of the movable accessory 131 on the steep slope 223a immediately after this because the rotational speed of the drive motor 211 is low.

  Specifically, there is a possibility that the meshing state of the gear mechanism 240 may be suddenly switched from the advancing action state in which the drive gear 901 drives the accessory gear 903 to the accessory-driven state in which the accessory gear 903 operates the drive gear 901. . In the present embodiment, backlash is suppressed by setting the rotational speed of the drive motor 2001 in accordance with the high speed operation of the movable accessory 131 on the steep slope 223a while obtaining a large torque at a low speed on the switching path 222. be able to.

(Modification of the embodiment)
Next, a modification of the present embodiment will be described. In this modification, the shape of the movable accessory and the mechanism for moving the movable accessory are different from the above-described embodiment. In the following description, the same points as those of the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

(Configuration of pachinko gaming machine according to this variation)
A pachinko gaming machine according to this modification will be described with reference to FIG. FIG. 19 is an explanatory diagram showing a pachinko gaming machine according to this modification. In FIG. 19, the pachinko gaming machine 1900 is provided with a movable accessory 1901 on the right side of the image display unit 104. The movable accessory 1901 is a large accessory that represents a “sword”, and is tilted and moved to the front of the image display unit 104 during a predetermined performance. In the figure, the position indicated by the solid line indicates the retracted position, and the position indicated by the broken line indicates the advance position. At the time of operation, it is possible to move from the retracted position to the advanced position at high speed and perform an impact operation.

(Configuration and operation of movable accessory according to this modification)
FIG. 20 is an explanatory diagram showing the configuration and operation of the movable accessory according to the present modification. FIG. 20 shows a view of the movable accessory 1901 viewed from the back. In (x) of FIG. 20, the movable accessory 1901 includes a drive motor 2001. As the drive motor 2001, a stepping motor is used. The drive motor 2001 is connected to the drive gear 2002, the driven gear 2003, and the accessory gear 2004 that constitute the gear mechanism 2000.

  Specifically, the drive motor 2001 rotates the drive gear 2002 provided on the rotation shaft of the drive motor 2001. The drive gear 2002 is meshed with the driven gear 2003 and rotates the driven gear 2003. The driven gear 2003 is meshed with the accessory gear 2004 and rotates the accessory gear 2004. A rotation shaft 2010 is connected to the accessory gear 2004, and the arm 2011 is rotated about the rotation shaft 2010 as a support shaft. In addition, the arm 2011 is provided with a decorative portion 2020 that is shaped like a “sword”. The decoration unit 2020 includes a light emitter such as an LED.

  Next, the operation of the movable accessory 1901 will be described. When the drive motor 2001 is driven to rotate at the retracted position shown in (x), the drive force of the drive gear 2002 is transmitted to the accessory gear 2004 via the driven gear 2003. With this driving force, the arm 2011 rotates about the rotation shaft 2010 as a support shaft. And the decoration part 2020 moves to the front surface of the image display part 104 gradually, as shown to (y). Furthermore, when the drive motor 2001 rotates, as shown in (z), the drive motor 2001 stops until a predetermined production time elapses at the most advanced position.

  When a predetermined effect time has elapsed, the drive motor 2001 is rotated in the reverse direction, whereby the arm 2011 is rotated in the reverse direction about the rotation shaft 2010 as a support shaft and returned to the retracted position. Such an operation of (x) → (y) → (z) is performed at high speed, and an impactful operation is realized. Specific control during operation will be described.

  Here, in the balance of the movable accessory 1901, the position (y) is a position where force in the advance direction and the advance direction does not act. That is, the movable accessory 1901 is subjected to a force to return to the retracted position due to its own weight until reaching the position (y), and when it exceeds the position (y), a propulsive force in the advancing direction is exerted due to its own weight. To do. That is, the area from (x) to (y) is a general area where the decorative portion 2020 tries to return to the retracted position by its own weight, and moves by the driving force of the drive motor 2001. In addition, the areas (y) to (z) are not only the driving force of the drive motor 2001 but also a special area where the decorative portion 2020 attempts to move in the advance position direction due to gravity (self-weight).

  For this reason, if the decorative portion 2020 is moved from (x) → (y) → (z), so-called backlash may occur. The backlash here means that the direction of transmission of force between the gears (gear mechanism 2000) is changed and the gears are reversed by the decoration unit 2020 operating faster than the drive motor 2001. Therefore, in the present embodiment, in the region from (y) to (z), the backlash is suppressed by rotating the drive motor 2001 at a high speed in accordance with the high-speed movement of the decoration unit 2020. .

(Gear mechanism engagement)
Next, the meshing state of the gear mechanism 2000 of the movable accessory 1901 will be described with reference to FIGS. 21-1 and 21-2. FIG. 21A is an explanatory diagram illustrating a meshing state of the gear mechanism of the present modification. In FIG. 21A, a gap α that is play is provided between the gears 2002 to 2004. The meshing state of the gear is switched by the gap α.

  21A shows a state when the movable accessory 1901 passes through the general region (region (x) → (y) in FIG. 20). In the general region, the driving force of the driving gear 2002 is transmitted to the driven gear 2003 and the accessory gear 2004, whereby the movable accessory 1901 operates. (A) is a state in which the driving gear 2002 transmits driving force to the driven gear 2003 and the accessory gear 2004 (hereinafter referred to as “advance action state”), and corresponds to the first gear state of the present invention.

  In the special region (region (y) → (z) in FIG. 20), the movable accessory 1901 is accelerated by the propulsive force. The driving force is gravity (self-weight). At this time, the drive gear 2002 is also rotated in accordance with the acceleration of the movable accessory 1901 so that the gears 2002 to 2004 are not caused to act as shown in FIG. The meshing state of the gears 2002 to 2004 shown in (b) is hereinafter referred to as “non-operation state” and corresponds to the second gear state of the present invention.

  In the non-actuated state, the gears do not act, but the drive gear 2002 is in contact with the driven gear 2003 and the accessory gear 2004 from the direction in which a force can be exerted. That is, in the non-actuated state, the gap α is generated only on the side where the projections 2012 to 2014 of the gears 2002 to 2004 are not in contact with each other, as in the advanced action state shown in FIG. Yes.

  In this way, by rotating the drive gear 2002 at a rotational speed that matches the acceleration of the movable accessory 1901, the drive gear 2002 cannot follow the operation of the accessory gear 2004 and moves from the drive gear 2002 to the accessory gear 2004. There is no force in the direction of obstruction, so backlash can be suppressed.

  Further, in the special region, the meshing state of the gears 2002 to 2004 is not limited to the non-operating state, and the speed is higher than the moving speed of the movable accessory 1901, that is, the drive gear 2002 and the driven gear 2003 and the combination gear. It is good also as an advance action state which transmits a driving force to the thing gear 2004. Even if it is set as such a structure, the force of the direction which prevents operation | movement from the drive gear 2002 to the accessory gear 2004 does not act in a special area | region, and backlash can be suppressed.

  In this modification, the non-operating state is a state in which the driving gear 2002 is in contact with the driven gear 2003 and the accessory gear 2004 from the direction in which force can be applied as shown in FIG. Absent. Here, another example when the movable accessory 1901 passes through the special area will be described with reference to FIG.

  FIG. 21B is an explanatory diagram of another example of the meshing state of the gear mechanism. FIG. 21-2 shows a state when the movable accessory 1901 passes through the special area. The gap α is generated on both sides (gap α3, α4) of the convex portions 2012-2014 of the gears 2002-2004. In the special area, the drive gear 2002, the driven gear 2003, and the accessory gear 2004 are not interfered with each other since the 2001 is rotated at a speed equivalent to the moving speed of the movable accessory 1901, as in FIG. Rotate (without action).

  In this modified example, the moving position is moved to the advanced position in the non-actuated state. However, in the process of reaching the advanced position, the driving force of the driving gear 2002 is used as the driven gear 2003 and the accessory gear after the driving force is lost. It is also possible to adopt a configuration for transmitting to 2004, that is, a configuration for shifting from the non-action state to the advancement action state.

  In this case, in order to shift each gear 2002 to 2004 more smoothly from the non-acting state to the advancing action state, that is, when the gears 2002 to 2004 are shifted from the non-acting state to the advancing action state, the impact associated with the switching of the meshing state by the gap α. In order to further suppress the above, it is desirable to make the gap α3 smaller than the gap α4. In other words, in the non-actuated state, it is desirable that the engagement state is closer to the advanced action state than the accessory-driven state (a state in which power is transmitted from the accessory gear 2004 to the drive gear 2002).

  It should be noted that, when shifting from the non-acting state to the advancing action state, it is most desirable that the drive gear 2002 exerts a force on the driven gear 2003 and the accessory gear 2004 as shown in FIG. It is the state which is made to contact from the possible direction. If it does in this way, it can be set as the state which contacted each gear 2002-2004 similarly to the advance action state in a non-action state, and can suppress the impact accompanying switching of the meshing state by gap (alpha) most. Thereby, backlash can be suppressed most effectively.

  As described above, this modification has the same effects as those of the above-described embodiment. Specifically, in this modified example, in the general region (region (x) → (y) in FIG. 20), the gear mechanism 2000 is set in the advanced action state to drive and rotate the drive gear 2002, while in the special region (FIG. 20). In the (y) → (z) region), the gear mechanism 2000 is driven so as to have a rotational speed at which the gear mechanism 2000 is in the advanced state or the non-active state based on the operation (acceleration) of the movable accessory 1901 with a predetermined advance output. The gear 2002 is driven to rotate.

  Accordingly, the backlash can be prevented without the drive gear 2002 being unable to follow the accessory gear 2004 against the sudden acceleration of the movable accessory 1901 in the special region. Thereby, the large movable accessory 1901 can be operated at high speed, and a powerful effect can be performed.

  In the present embodiment, the present invention is applied to the pachinko gaming machine 100. However, the present invention is not limited to this, and the present invention can also be applied to other gaming machines such as a rotary gaming machine.
