Description

  The present invention relates to a movable object unit and a gaming machine, and more particularly to a movable object unit having a movable object that moves in the vertical direction.

  In a pachinko machine, a ball that has been bulleted flows down a game area (an area formed on or near the game board surface for realizing a game or production by the flow of the game ball). In the process of flowing down, the game ball turns while colliding with a game nail (also referred to as a gauge) or a windmill in the game area, and the flow direction changes. As a result, a predetermined prize ball is paid out when a game ball is won at various winning holes arranged on the game area, while a prize ball is paid out when a game ball flows into the out port without winning at any of the winning holes. Not done. The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the game ball flowing down and expecting the game ball to be won and the prize ball paid out.

  There are various game areas for realizing games based on the flow of game balls, such as a winning device having a entrance for a game ball to enter, a display device for displaying a game state, a movable object unit having a movable object, etc. These members are arranged. The player's interest can be attracted by performing the effect by using the display device, the movable object unit, or the like. In recent years, as such a movable object unit, there is provided a movable object unit that has a movable member arranged in front of the display unit and is configured to move the movable member in the vertical direction to enhance the interest of the player. Has been.

  However, in a movable object unit having a movable object that moves in the vertical direction, the load on the driving means when the movable object is raised tends to be larger than when the movable object is lowered. In particular, in recent years, movable objects have become larger, and overloading of driving means for large movable objects may become a problem. In view of such a problem, a movable object unit is provided that can reduce the load on the driving means during ascent (see, for example, Patent Document 1).

JP 2006-223659 A

  The movable object unit described in Patent Document 1 includes a movable member that moves up and down, and a lifting and lowering operation device that moves the movable member up and down. The lifting / lowering operation device includes a parallel link mechanism, an electric motor, a drive gear, a rotation operation member, a rotation device, and an operation bar member as a drive device that applies a lifting / lowering movement force to the parallel link mechanism, and a lifting force generated by the drive device. And a coil spring as a lifting force assisting mechanism.

  According to the movable object unit described in Patent Literature 1, the ascending force by the driving device can be assisted by the coil spring, and the load on the electric motor when the movable member is raised can be reduced. However, when the coil spring deteriorates after a long period of use, the coil spring cannot assist the lifting force, and there is a possibility that the load on the electric motor cannot be reduced.

  The present invention has been made in view of the above circumstances, and provides a movable object unit or the like that can reduce the load on the drive motor when the movable object rises, regardless of deterioration due to use or the like. Let it be an exemplary problem.

  In order to solve the above-described problem, a movable object unit as an exemplary aspect of the present invention includes a movable object that moves between an upper end position and a lower end position around a shaft portion provided in a support member; It has an arm member having a connecting portion connected to a movable object, a cam member engaged with the arm member, and a motor for rotationally driving the cam member, and one of the cam member and the arm member includes: A protrusion projecting toward the other is formed, and the other of the cam member and the arm member is formed with a protrusion hole into which the protrusion is inserted, and the driving force of the motor via the arm member and the cam member. The projection hole is longer than the outer shape of the projection, and the projection is movable within the projection hole, and is relative to the shaft. Is configured to change, the protrusion and the shaft The distance A is configured such that the movable object than the movable object is lowered toward the lower end position from the upper end position is longer in a state that rises toward the upper position from the lower end position.

  The movable object is transmitted between the upper end position and the lower end position about the shaft portion fixed to the support member by transmitting the driving force of the driving means via the arm member. An arm member is connected to the movable object, and a cam member is connected to the motor. One of the arm member and the cam member is formed with a projection, and the other is formed with a projection hole into which the projection is inserted. By inserting the projection into the projection hole, the arm member The driving force of the motor is transmitted to the movable object via the cam member.

  The protruding portion is configured to move within the elongated hole-shaped protruding hole portion so as to approach or move away from the shaft portion and change the distance from the shaft portion. The movable object moves around the shaft part, and a rotational moment due to the weight of the movable object acts on the shaft part. Further, the shaft portion is also configured so that the driving force transmitted through the projection portion also acts, and the rotational moment acting on the shaft portion increases as the distance between the shaft portion and the projection portion increases. The relationship between the driving force transmitted to the shaft portion via the protrusion and the distance between the shaft portion and the protrusion becomes larger as the distance between the shaft portion and the protrusion is longer. Therefore, as the distance between the shaft portion and the projection portion is longer, the movable object can be raised with a smaller driving force, and the load on the motor can be reduced.

  Further, when the movable object rises, the movable object moves against the gravity, so that the load on the motor becomes larger than when the movable object is lowered. Therefore, a small driving force can be obtained by making the distance between the projection and the shaft when the movable object rises, where the load of the motor is relatively large, longer than the distance between the projection and the shaft when the movable object is lowered. Even so, the rotational moment with respect to the shaft portion can be increased, and the load on the motor during ascent can be reduced.

  Note that the vertical direction and the left-right direction in the present invention are directions as viewed from the player in front of the gaming machine when the movable object unit is attached to the gaming machine. In the structure arrange | positioned inclining, it is not restricted to the direction visually recognized from the player, It is a concept also including the direction which makes the upper surface of a movable object unit upward.

  The protrusion hole portion is provided with an arc-shaped recess, and the protrusion is in contact with the recess when at least one of the movable object is in the upper end position and the movable object is in the lower end position. The arm member is configured so as to abut against the dent in a slightly moved state, and the connecting portion of the arm member has a substantially constant vertical position when the projection and the dent are in contact with each other. It may be configured.

  By providing the recess in the arm member, the driving force of the motor can be transmitted to the arm member and the movable object by moving the protrusion along the recess. In addition, the protrusion is configured to abut on at least one of the upper end position and the lower end position, and to abut on the recess even in a state slightly shifted from this position.

  Further, the connecting portion of the arm member has a substantially identical position in the vertical direction of the connecting portion of the movable object when the protruding portion is in contact with the recessed portion of the protruding hole portion. Even if the projecting part moves in the projecting hole part in a state where the contact is made, the movable object does not move in the vertical direction.

  Specifically, in a configuration in which a protrusion is provided on the cam member and a protrusion hole is provided on the arm member, even if the protrusion rotates, the movement is absorbed by the recess and is not transmitted to the arm member. Configure. Since the arm member does not move, the movable object can be prevented from moving in the vertical direction. For example, if the movable object is at the upper end position in a state where the protrusion is in contact with the recess, even if the protrusion moves slightly from this state, the movable object does not move in the vertical direction and the upper end position is set. Can be maintained.

  As described above, by providing the recess, even when the position of the protrusion corresponding to the upper end position (or lower end position) of the movable object is slightly shifted, the movable object is arranged at the upper end position (or lower end position). Therefore, it is possible to perform drive control of the movable object without requiring strict positional accuracy, and it is possible to simplify the control means.

  Furthermore, by forming the recesses indented with respect to the wall surface that constitutes the projection hole, the projections at the positions corresponding to the upper end position and / or the lower end position (contact position with the recesses) once vibrate, etc. Therefore, it is possible to prevent unintentional removal from the recess, and the movable object can be locked at the upper end position and / or the lower end position. In particular, when vibration is applied to the movable object unit, such as during transportation, the movable object can be prevented from unintentionally moving.

  Further, it is desirable that the movable object unit further includes an urging means for urging the arm member or the movable object in the moving direction when the movable object moves upward. By providing the urging means, an urging force different from the driving force transmitted through the arm member acts on the movable object, so that the load on the motor can be further reduced. Further, by urging the movable object at the upper end position in the upward direction by the urging means, it is possible to prevent the movable object once moved to the upper end position from unintentionally descending due to its own weight.

  The urging means only needs to be configured to apply an urging force to the arm member or the movable object. For example, an elastic body such as a spring or rubber, or a molded product such as a deformable resin. Can be illustrated. Further, the urging means may be arranged in contact with the movable object or the arm member so that the urging force acts directly on the movable object or the like, or may be configured to move the movable object or the like via another member. The urging force may act indirectly.

  In addition, a game machine as another exemplary aspect of the present invention includes a game board that realizes a game, a game machine frame that includes the game board, and the movable object unit described above. The unit is provided on at least one of the game board and the gaming machine frame.

Since the load when the movable object is raised can be reduced, the movable object can be moved smoothly and quickly, and a powerful performance can be realized.

  Moreover, a movable object can be appropriately arrange | positioned at an upper end position and a lower end position, the positional accuracy of a movable object can be improved, and the quality of production can be improved. For example, a movable object can be arranged in front of the image display device, and an effect in which the image of the image display device is interlocked according to the position of the movable object can be realized, and the player can be enjoyed without getting tired of the player. Can be increased.

  Note that the game board is to realize a game in a gaming machine, for example, to realize a game by the flow of game balls. The movable object unit may be configured to be mounted on the game board or the gaming machine frame, and may be configured to be directly mounted on the game board or the gaming machine frame, or may be a game board or gaming machine frame. The member may be arranged between the two and may be configured to be mounted indirectly to the game board or the game machine frame. The gaming machine frame is a frame member or a group of frame members that encloses the game board, and surrounds the side and front of the game board. For example, an outer frame containing a game board, a front frame, a front frame, or a combination thereof corresponds to the gaming machine frame.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, the distance between the protrusion and the shaft when the movable object is lifted, where the load on the motor is relatively large, is longer than the distance between the protrusion and the shaft when the movable object is lowered. Even with a small driving force, the rotational moment with respect to the shaft portion can be increased, and the load on the motor during ascent can be reduced.

  In addition, by providing a recess in the projection hole provided in one of the cam member and the arm member that transmits the driving force of the motor to the movable object, the movable object is in a state where the projection is in contact with the recess. It can be configured not to move in the vertical direction. For example, if the movable object is at the upper end position in a state where the protrusion is in contact with the recess, even if the protrusion moves slightly from this state, the movable object does not move in the vertical direction and the upper end position is set. Can be maintained. Therefore, even if the position of the protrusion corresponding to the upper end position (or lower end position) of the movable object is slightly shifted, the movable object can be arranged at the upper end position (or lower end position), and strict positional accuracy is achieved. Therefore, it is possible to control the driving of the movable object without requiring the control, and it is possible to simplify the control means.

  Furthermore, it is possible to prevent the protrusion at the position corresponding to the upper end position and / or the lower end position (contact position with the recess) from unintentionally coming out of the recess due to vibration or the like. The position and / or the lower end position can be locked. In particular, when vibration is applied to the movable object unit, such as during transportation, the movable object can be prevented from unintentionally moving.

As the cam member 44 rotates in the X direction, the protrusion 44d moves upward while moving in the right direction within the protrusion hole 42c. The arm member 42 is pressed upward by the protrusion 44d and rotates in the −Y direction (clockwise direction) about the rotation shaft 46a. As the arm member 42 rotates in the −Y direction, the engagement hole portion 42a of the arm member 42 moves upward, and the engagement portion 41c of the movable object 41 is pressed upward. Accordingly, the movable object 41 moves upward along the guide hole 46b.

  Then, when the motor is driven 60 steps from the state shown in FIG. 7B, the cam member 44 is rotated in the X direction to be in the state shown in FIG. As the cam member 44 rotates, the projecting portion 44d moves upward while moving leftward within the projecting hole portion 42c, and the arm member 42 further rotates in the -Y direction. As the arm member 42 rotates in the -Y direction, the engagement hole 42a of the arm member 42 moves further upward, and the movable object 41 moves upward along the guide hole 46b to move to the upper end position. It becomes. When the production control board receives the detection signal of the protruding piece 44b from the detection sensor 47, the production control board determines that the movable object 41 is at the upper end position.

  Thus, by rotating the cam member 44 in a certain direction by the motor 43, the movable object 41 can be moved from the upper end position toward the lower end position, and can be moved from the lower end position toward the upper end position. In addition, when moving the movable object 41 from the upper end position toward the lower end position, the load on the motor 43 is relatively small because the movable object 41 is lowered, but the movable object 41 is moved from the lower end position toward the upper end position. At this time, since the movable object 41 is moved against the gravity, the load of the motor 43 becomes relatively large.

  However, in the state where the movable object 41 is moved from the lower end position toward the upper end position, the distance between the protrusion 44d and the rotation shaft 46a is longer than in the state where the movable object 41 is moved from the upper end position toward the lower end position. Thus, the driving force applied to the rotating shaft 46a via the protrusion 44d is made relatively large. Therefore, the movable object 41 can be raised with a relatively small driving force, and the load on the motor 43 can be reduced.

  Thus, according to the configuration that reduces the load on the motor by changing the distance between the protruding portion and the rotating shaft between rising and falling, compared to the configuration that reduces the load on the motor with a spring or the like, it is longer There is little deterioration in use, and the load on the motor can be continuously reduced.

  Further, the protrusion 44d is at the upper end position and the movable object 41 is at the upper end position, the protrusion 44d is at the lower end position and the movable object 41 is at the lower end position, and the cam member 44 is rotated 180 degrees to thereby move the protrusion 44d from the upper end position to the lower end position. It is configured to move to a position (or move from a lower end position to an upper end position). When the cam member 44 is rotated at a constant speed in such a configuration, the movement distance in the vertical direction of the protrusion 44d is relatively short near the upper end position and the lower end position, and compared at an intermediate position between the upper end position and the lower end position. Become longer.

  Therefore, even when the cam member 44 is rotated at a constant speed, the moving speed of the movable object 41 can be changed in the vertical direction. Specifically, the movement speed in the vertical direction is high near the middle between the upper end position and the lower end position, and the movement speed is low in the vertical direction in the vicinity of the upper end position and in the vicinity of the lower end position. Therefore, even if the cam member 44 is rotated at a constant speed, the movable object 41 can be disposed relatively long in the vicinity of the upper end position and in the vicinity of the lower end position. In addition, by detecting the position of the cam member 44 at the upper end position that is relatively long, the detection accuracy of the detection sensor 47 can be improved.

  FIG. 8 is a partial enlarged view in which the portion A shown in FIG. 6 is enlarged. As shown in FIG. 8, at the center in the left-right direction of the protruding hole portion 42c of the arm member 42, an upper recessed portion 42d recessed upward and a lower recessed portion 42e recessed downward are formed. The upper recessed portion 42d is configured such that the protruding portion 44d abuts when the movable object 41 is in the upper end position.

  B1 shown in FIG. 8 indicates the protrusion 44d in a state where the movable object 41 is in the upper end position. In this state, the protrusion 44d is in contact with the approximate center of the upper recess 42d in the left-right direction. Further, the protrusion 44d contacts the upper recess 42d even at a position (B2 in the drawing) where the cam member 44 is slightly rotated in the X direction from the state in which the movable object 41 is at the upper end position. Further, the protrusion comes into contact with the upper recessed portion 42d even at a position just before the movable object 41 is the upper end position (B3 in the drawing).

  The arc shape of the upper recessed portion 42d is formed along the rotation locus T1 of the protruding portion 44d rotated by the cam member 44. Therefore, when the protrusion 44d moves along the upper recess 42d, the upper recess 42d (projection hole 42c) is not pressed by the protrusion 44d, and the arm member 42 does not rotate. Therefore, in a state where the projection 44d is moving along the upper recess 42d (a state where the projection 44d is in contact with the upper recess 42d), the movable object 41 remains at the upper end position.

  As described above, the protrusion 44d and the upper recess 42d are brought into contact with each other when the movable object 41 is in the upper end position, so that the position of the protrusion 44d corresponding to the upper end position of the movable object 41 is slightly shifted. However, the movable object 41 can be disposed at the upper end position, and the drive control of the movable object 41 can be performed without requiring strict positional accuracy.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary. For example, in the present embodiment, the movable object is lifted only by the driving force of the motor, but the arm member or the movable object is biased in the direction in which the movable object is lifted by an elastic member such as a spring or rubber.
