Description

  The present invention relates to a pachinko gaming machine, and is particularly suitable for detecting the origin position of a movable decorative body arranged on a game board surface.

In the pachinko machine, various board parts such as a prize opening, a windmill, a symbol display device, and an electrical decoration device are provided on the board of the game board in order to diversify the game contents. For example, the stage effect has been enhanced by moving and deforming a movable panel surface component such as a movable decorative body in various directions and modes triggered by winnings during the game and other changes in the situation.
By the way, in driving the movable decorative body as described above, it is important to accurately control the position of the movable body provided in the movable decorative body in order to enhance the effect.
For this reason, in a movable decorative body that can move up and down with respect to the board surface, sensors are placed at the start and end positions of the movable body that is actually movable, and the movable body is detected by which sensor when the power is turned on. The position of the movable body is grasped according to whether it has been done, and is returned to the original position.
Patent Document 1 discloses a pachinko gaming machine in which a rotational position such as an origin position of a rotating decorative member is determined by output signals of two sensors.
JP 2006-198177 A (FIG. 8)

However, when configured as described in Patent Document 1, two sensors are required for position control of the movable body, and thus there is a problem in that component costs, manufacturing costs, and software costs increase.
Thus, for example, it is conceivable to control the position of the movable body by detecting the origin position of the movable body provided on the movable decorative body with one sensor.
FIG. 11 is an explanatory diagram of a method of detecting the origin position of the movable body by one sensor. Here, a case where the origin position of a movable body that can move up and down is detected will be described as an example.
In FIG. 11, 201 is a light shielding plate provided on a movable body (not shown), 202 is a sensor, 202 a is a light emitting unit 202 ab of the sensor 202, and a light receiving unit of the sensor 202.
As shown in FIG. 11, when the light shielding plate 201 provided on the movable body is away from the sensor 202, for example, at the highest position, the light receiving unit 202b of the sensor 202 receives light from the light emitting unit 202a. It is in. When the light-shielding plate 201 is lowered from this state, the light-shielding plate 201 shields light between the light-emitting portion 202a and the light-receiving portion 202b of the sensor 202, and the sensor 202 enters a light-shielding state. In this case, even when the movable body is lowered to the lowest position, the sensor 202 remains in the light-shielded state where the light is shielded by the light-shielding plate 201. When the movable body rises from this state, the sensor 202 changes from the light shielding state to the light receiving state. Therefore, for example, if the origin position of the movable body is determined based on the timing at which the sensor 202 changes from the light receiving state to the light shielding state, the origin of the movable body can be detected by one sensor.

However, in the method of detecting the origin position shown in FIG. 11, the light shielding plate 201 is lowered too much for some reason as shown in FIG. 12, and the sensor 202 changes from the light shielding state to the light receiving state at the lowest lowered position. Then, the sensor 202 is switched from the light receiving state to the light shielding state while the movable body is rising from the lowest position. Therefore, when the origin position is determined based on the timing when the sensor 202 is changed from the light receiving state to the light shielding state as described above, there is a problem that the origin position is erroneously detected. That is, in the pachinko gaming machine, if the number of sensors of the movable decorative body is reduced in order to reduce the size and cost, the origin position of the movable body may be erroneously detected.
The present invention has been made in view of the above, and an object thereof is to provide a pachinko gaming machine capable of accurately detecting the origin position of a movable body while reducing the size and cost of the movable decoration device. To do.

  In order to achieve the above object, the present invention according to claim 1 is a drive for driving the movable decorative body in a pachinko gaming machine including a movable decorative body supported by a support member fixed to the game board so as to be movable up and down. A sensor comprising a mechanism, a light emitting unit and a light receiving unit for receiving light emitted from the light emitting unit, and a light emitting unit that is provided on the movable decorative body and emits light even when the movable decorative body is lowered from the lowest position. A light shielding member configured to shield light emitted from the light receiving portion to the light receiving portion, and the rising edge at which the sensor changes from the light receiving state to the light shielding state by the light shielding member when the movable decorative body is lowered. Control is performed to detect the origin of the movable decorative body, and when the movable decorative body is raised, the light shielding member causes the sensor to change from a light shielding state to a light receiving state. And control means for controlling to perform origin detection of the movable decorative body in the edge, further comprising a characterized.

According to a second aspect of the present invention, in the pachinko gaming machine according to the first aspect, the drive mechanism is a single motor, a gear group that transmits a driving force from the motor, and a rotation by the gear group. It is characterized by comprising a cam to be driven and an arm that makes one end abut against the cam and swings by engaging the other end with the main movable body.
According to a third aspect of the present invention, there is provided a method for detecting an origin of a movable decorative body supported by a support member fixed to a game board so as to be movable up and down, and when the movable decorative body is lowered, The origin of the movable decorative body is detected at the rising edge where the sensor changes from the light receiving state to the light shielding state by the light shielding member provided on the movable decorative body, and when the movable decorative body is raised, the light shielding member The origin of the movable decorative body is detected at the falling edge where the sensor changes from the light shielding state to the light receiving state.

  According to the present invention, the movable decorative body is lowered by the driving mechanism after the light shielding member is lengthened so that the sensor does not change from the light shielding state to the light receiving state even when the light shielding member is lowered below the lowest position. When the sensor is in the rising edge where the sensor changes from the light-receiving state to the light-blocking state, and when the movable decorative body is raised by the drive mechanism, the moving decoration is displayed at the falling edge where the sensor changes from the light-shielding state to the light-receiving state. The origin of the body was detected. In this way, the number of sensors for detecting the origin of the movable decorative body is reduced from the conventional two to one, thereby reducing the size and cost of the movable decorative body, and accurately positioning the origin of the movable body. It becomes possible to detect.

The movable decorative body unit 40 includes a movable decorative body 31 that is shaped like a black-beard face (main movable body) 32 and a trunk (secondary movable body) 35, and a drive mechanism 50 for driving the movable decorative body 31. And.
The movable decorative body 31 is supported in a vertically movable state by a support member 60 disposed on the back side of the center member 7. Specifically, the movable decorative body 31 is in the intermediate height position (initial position) shown in FIG. 2A in the non-operating state, while the drive mechanism 50 is driven during operation (b). After descending to the lowest position shown in (1), it immediately rises (jumps) to the highest position shown in (c). Then, it returns to the initial position shown in (a) and stops.

As shown in FIGS. 4 and 5, the movable decorative body 31 includes a face part (main movable body) 32 including the head and a body part (secondary movable body) supported by the back side of the face part 32 so as to be movable up and down. 35. While the face portion 32 is disposed on the front surface of the support member 60, a guided piece 32 a protruding from the back surface of the face portion 32 is protruded rearward through a guide slit 61 provided on the support member 60. . A detected member (light-shielding plate) 71 detected by a sensor 70 made of a photo interrupter is fixed to the end of the guided piece 32a. The sensor 70 is configured in a substantially U-shape, and a light emitting unit 70a and a light receiving unit 70b are arranged to face each other on the inner side surface.
The face part 32 supports the body part 35 so that it can be moved up and down by fitting a guide pin 32 b projecting from the back face into a long hole 35 a provided in the body part 35. The trunk | drum 35 is supported so that it may descend | fall by own weight.

When the face portion 32 is at the highest position shown in FIGS. 2C and 4, the body portion 35 is lowered by its own weight and protrudes downward from the lower end portion of the face portion 32. In this state, not only the face portion but also the trunk portion is visible from the front.
When the face portion 32 is at the lowest position shown in FIGS. 2B and 5, the body portion 35 is concealed on the back side of the face portion 32, and the body portion cannot be viewed from the front.
Each operation of the face portion and the trunk portion during the raising / lowering operation of the movable decorative body 31 can be realized by the first restriction member 62 and the second restriction member 63 provided on the support member 60.
That is, the support member 60 includes a first restricting member 62 that defines an upper limit position of the torso 35 when the face 32 is at the highest position, and a face of the torso 35 when the face 32 is at the lowest position. And a second restricting member 63 that raises the relative height position to 32.
The first restricting member 62 is a protruding piece that protrudes forward from a predetermined position along the movement path of the body portion 35, and is in contact with the upper portion of the body portion 35 when the face portion 32 is at the highest position shown in FIG. By touching, the body part 35 is surely shifted to a state where it droops, and the posture of the body part 35 protruding downward from the face part 32 is corrected so as not to tilt.
The second restricting member 63 is a protruding piece that protrudes forward from a predetermined position along the movement path of the torso 35, and when the face 32 is at the lowest lowered position shown in FIG. By abutting, the body part is surely pushed into the back side of the face part and concealed.
Since the movable decorative body 31 is disposed behind the front plate 66 provided on the front surface of the support member, a part of the face is concealed by the front plate 66 in the lowered state of FIG.

Next, the relationship between the raising / lowering operation of the movable decorative body and the drive mechanism (operation of the movable decorative body unit) will be described with reference to FIG. In addition, each left figure of FIG. 6 (a) (b) and (c) is a front view of a movable decoration body unit, and each right figure is a perspective view.
6A shows a state in which the movable decorative body 31 is in the initial position shown in FIG. 2A, and FIG. 6B shows the lowermost position in which the movable decorative body is shown in FIG. 6 (c) shows a state in which the movable decorative body is at the highest position shown in FIG. 2 (c).
The drive mechanism 50 disposed on the back side of the support member 60 is integrated with a motor 51, gears (gear groups) 53 and 54 that sequentially mesh with the output gear 52 of the motor 51, and a small gear 55 that meshes with the gear 54. And an arm 57 pivotally supported by a shaft 65 provided on the support member 60 so as to be swingable in the vertical direction. The arm 57 has one end 57a that functions as a cam follower and the other end 57b that engages the back side of the face 32. The one end portion 57a is always in contact with the outer peripheral surface (cam surface) 56a of the cam 56, and is configured to be in sliding contact with the cam surface 56a when the cam 56 rotates. The face portion 32 (or the arm 57) is always urged upward by the elastic member 58, and the one end portion 57 a of the arm 57 is always pressed against the cam surface 56 a of the cam 56 by the urging force of the elastic member 58.

As shown in FIG. 7, an elongated hole 57c is formed in the other end portion 57b of the arm 57, and a pin 36 protruding from an appropriate position on the back surface of the face portion 32 is loosely fitted in the elongated hole 57c.
The cam surface 56a of the cam 56 includes a curved surface portion 56a-1 in which the distance from the central axis 55a of the small gear 55 increases in a curved manner, a step portion 56a-2 provided at the end portion of the curved surface portion 56a-1, 6A, the motor 51 is stopped when the movable decorative body is in the initial position as shown in FIG. 6A, and the one end 57a of the arm is connected to the cam surface 56a by the urging force of the elastic member 58. The curved surface portion 56a-1 is kept in contact with the vicinity of the starting end portion. For this reason, the other end portion 57b of the arm is at the intermediate height position, and the movable decorative body 31 is held at the intermediate height position. At this time, the face 32 is visible from the front of the game board, but the body 35 is concealed by the front plate 66.

  When the motor 51 starts to rotate in the forward direction, the driving force is sequentially transmitted to the gears 52, 53, 54, and 55 as shown in FIG. 6B, and the cam 56 rotates in the direction of the arrow. The part 57a moves relatively toward the end part of the curved surface part 56a-1. As shown in the figure, when the one end portion 57a of the arm is located at the terminal portion of the curved surface portion 56a-1 (immediately before the stepped portion 56a-2), the other end portion 57b of the arm is at the lowest lowered position. Lowers to the lowest position. In the process in which the face portion 32 constituting the movable decorative body is lowered to the lowest lowered position by the other end portion 57b of the arm 57, the lowering range of the body portion 35 is restricted by the second restricting member 63. The height of the relative height of the face portion 32 rises and is concealed on the back side of the face portion 32 (FIGS. 2B and 5).

When the arm swings, the pin 36 loosely fitted in the elongated hole 57c moves in the elongated hole, so that the face pressing operation by the other end of the arm becomes smooth.
When the motor 51 further rotates in the forward direction by a predetermined angle, the cam 56 further rotates in the direction of the arrow as shown in FIG. 6C, so that the one end portion 57a of the arm gets over the step portion 56a-2 and the elastic member 58 It falls on the starting end of the curved surface portion 56a-1 by the restoring force. As shown in the drawing, when the one end portion 57a of the arm is positioned on the starting end portion of the curved surface portion 56a-2, the other end portion 57b of the arm is in the highest position, so that the movable decorative body 31 reaches the highest position. When the face portion 32 constituting the movable decorative body is pushed up to the highest position by the other end portion 57b of the arm 57, the body portion 35 is projected downward from the face portion 32 by its own weight and is visible from the front of the game board. It becomes a state (FIG. 2 (c), FIG. 4). At this time, since the upper range of the upper portion of the trunk portion 35 is regulated by the first regulating member 62, the upper portion of the trunk portion 35 can reliably project downward from the lower end portion of the trunk portion 35. Even if the trunk portion 35 is caught by the peripheral member, the projecting posture is correctly corrected by the first restricting member 62.

  As shown in FIG. 4, when the movable decorative body 31 is at the highest position, the sensor 70 at the fixed position does not detect the detected member (light-shielding plate) 71 integrated with the movable decorative body 31. In this state, when a control signal for driving the motor 51 is output from the control means to be described later, the motor 51 rotates in the forward rotation direction and starts to move down the movable decorative body 31 by the arm 57 against the elastic member 58. Let When the detected member 71 integrated with the face portion 32 constituting the movable decorative body 31 reaches the sensor 70 as shown in FIG. 5, the control means stops the driving of the motor 51 by the detection signal output from the sensor 70. The movable decorative body 31 is pulled up by a predetermined distance by the force of the elastic member 58 and maintains the stopped state in the initial state of FIG.

  As described above, in the present embodiment, the face 32 as the main movable body and the trunk 35 as the secondary movable body are separate members, and the trunk 35 is suspended by the face 32 so as to be movable up and down. Therefore, the entire movable decorative body 31 can be moved up and down only by moving up and down only the face part 32. While the face part 32 is lowered, the body part 35 is retracted to the back side of the face part 32, In the state where the face part 32 is raised to the highest position, the body part 35 protrudes downward from the lower edge of the face part. Since it comprised in this way, by setting the vertical dimension of the movable decoration body installation area | region 7a slightly larger than the vertical dimension of the face part 32 (only the height dimension of a trunk | drum), the face part 32 will be in an initial position. At some time and when it is in the lowest position, the torso 35 is concealed by the face 32 and the front plate 66 and cannot be seen from the front, but when the face 32 is raised, the torso 35 protrudes below the face 32, And since it moves above the front plate 66, it can be visually recognized from the front.

As described above, the movable decorative body unit 40 of the present embodiment is configured such that the driving force of the motor 51 is transmitted to the movable decorative body 31 via the cam 56, and the motor 51 rotates in the forward rotation direction. When the amount of rotation 51 reaches a predetermined amount, the elastic force of the elastic member 58 accumulated by the cam mechanism is released and the face portion 32 pops out.
In this embodiment, for example, even if the light shielding plate 71 is lowered too much from the lowest position for some reason, the light shielding plate 71 is lengthened so that the sensor 70 does not enter the light receiving state from the light shielding state, and then the motor When 51 is rotating forward, that is, when the light shielding plate 71 is lowered, as shown in FIG. 8, when the motor 51 reverses at the rising edge where the sensor 70 changes from the light receiving state to the light shielding state. That is, when the light shielding plate 71 is raised, the origin of the movable decorative body 31 is detected at the falling edge at which the sensor 70 changes from the light shielding state to the light receiving state. That is, in the present embodiment, the origin of the movable decorative body 31 is detected by the rising edge or the falling edge of the sensor 70 according to the rotation direction of the motor 51.

Next, a method for detecting the origin of the movable decorative body in the pachinko gaming machine according to the present embodiment will be described.
FIG. 10 is a diagram illustrating processing executed by the game control device when performing origin detection processing in the pachinko gaming machine according to the present embodiment. Note that the processing shown in FIG. 10 is realized by the CPU 142 of the lamp control board 141 executing a program stored in the ROM 143. The origin detection described below is performed, for example, every 0.5 ms to 5 ms.
In this case, the CPU 142 of the lamp control board 141 determines whether or not a rising edge in which the detection output of the sensor 70 changes from the light receiving state to the light shielding state is detected in step S1. Proceeding to S2, origin detection is performed with the position where the edge is detected as the origin position.
On the other hand, if the rising edge cannot be detected in step S1, the process proceeds to step S3, where it is determined whether or not a falling edge whose detection output from the sensor 70 changes from the light shielding state to the light receiving state is detected. If an edge is detected, the process proceeds to step S4. If a falling edge cannot be detected, the process returns to step S1.
In step S4, it is determined whether or not the rotation direction of the motor 51 is the normal rotation direction. If the rotation direction of the motor 51 is the normal rotation direction, the process proceeds to step S5, where the face 32 of the movable decorative body 31 is moved. A jump detection process is performed assuming that the jump has occurred. On the other hand, if it is determined in step S4 that the rotation direction of the motor 51 is not the normal rotation direction, the process proceeds to step S6, and a process in which the position where the falling edge is detected in step S3 is set as the origin position is performed.

  As described above, in the pachinko gaming machine according to the present embodiment, the sensor 70 changes from the light shielding state to the light receiving state even when the light shielding plate 71 fixed to the face 32 of the movable decorative body 31 is lowered too much from the lowest position. When the movable decorative body 31 is lowered by the motor 51 with the light-shielding plate 71 lengthened so as not to occur, at the rising edge where the sensor 70 changes from the light receiving state to the light-shielding state, the motor 51 also moves the movable decorative body. When 31 is rising, the origin of the movable decorative body 31 is detected at each falling edge at which the sensor 70 changes from the light shielding state to the light receiving state. In this way, even if the number of sensors for detecting the origin of the movable decorative body 31 is reduced from the conventional two to one to reduce the size and cost of the movable decorative body 31, the face portion can be reduced. Thus, the origin position of 32 can be accurately detected.

  In addition, as a method of returning the movable body of the movable decorative body to the origin position, for example, it may be possible to return to the origin position by using a stepping motor whose rotation angle can be controlled by the number of steps, but the stepping motor was used. In this case, the movable body may deviate from the original position due to a number of factors, such as differences in rotation angle due to molding errors of the movable decorative body, differences in rotation angle due to improper assembly, differences in individual manufacturing of the rotating gear, and backlash of the rotating gear. Therefore, the method using the position detection by the sensor as the origin as in the present invention is suitable.
