BACKGROUND OF THE INVENTION
The present invention relates to a shelf device for a gaming machine that rolls a game ball on a shelf body and drops and releases the game ball on a board surface from a predetermined position in the left-right direction .
[0002]
[Prior art]
As one of the conventional gaming machine shelf board devices, a pair of shelf board bodies are arranged in series so that the winning opening is located immediately below the opposed inner end, and each shelf board body is arranged in the longitudinal direction. There exists a thing of the structure which rotates independently centering on the fulcrum of an outer end part. For this reason, according to the rotation position of a pair of shelf main bodies, the fall discharge | release position of the game ball which rolls the upper surface differs.
[0003]
For example, when both of a pair of shelf main bodies are held in an inclined posture such that the inner end portions thereof are lowered, game balls that roll on the respective shelf plate main bodies gather at the inner end portions. As a result, the probability of falling and releasing onto the board from the portion directly above the winning opening becomes high, and the winning probability for the winning opening increases. Conversely, when both of the pair of shelf main bodies are held in an inclined posture such that the inner end thereof is raised, the game balls on each shelf main body are moved in the left-right direction ( It will fall on the board surface from the position deviated in the horizontal direction), and the winning probability to the winning opening becomes low. Furthermore, when the pair of shelf main bodies are held at the intermediate positions of the two types of tilting postures described above, the pair of shelf main bodies that are continuous along the left-right direction are in a posture close to the horizontal, Any part of the direction is dropped and released on the board surface, and the winning probability to the winning opening becomes close to the middle in the case of the two kinds of inclined postures described above.
[0004]
Thus, according to the shelf apparatus having the above-described configuration, the probability that a game ball discharged and dropped from the top of each shelf body onto the board surface can be changed to the winning opening can be changed. Since the shelf main body of this game is rotated, the change of the rolling mode of the game ball on the shelf main body becomes monotonous, and the fun of the game cannot be increased so much.
[0005]

In FIG. 1, reference numeral 14 denotes an out port for collecting a ball that has not won any winning device (winning port).
[0016]
Subsequently, the shelf board device R according to the present invention will be described. FIG. 3 is an enlarged view of a portion of the shelf board device R of FIG. 2, and FIG. 4 is a front view of the shelf board device R in a state in which the degree of curvature (curvature radius) of the shelf body 31 is the smallest. 5 is a front view of the intermediate bending state, FIG. 6 is a front view of the largest bending degree, and FIG. 7 is a plan view of the shelf apparatus R.
[0017]
As shown in FIGS. 1 to 7, the special symbol display device 7 is attached to the back side of a rectangular case body C whose front surface is open, and the inside of the case body C Constitutes a space S on the front surface of the special symbol display device 7. In addition, the shelf device R is horizontally disposed in the left and right direction (lateral direction) at the lower end of the space S, and is formed of a plate spring, a plastic plate, or the like that can be elastically deformed. It comprises a shelf main body 31 supported at both ends in the longitudinal direction so as to be movable in the same direction, and a drive mechanism D for elastically deforming the shelf main body 31 and holding it in a set curved shape. . As shown in FIGS. 1 to 4, a chevron-shaped decorative member 21 is attached to the upper half of the case body C so as to protrude from the front surface. Is formed with a warp inlet 22. Further, the pair of left and right vertical members 23 constituting the case body C have a width capable of forming a warp passage 24 therein, and a warp outlet 25 is formed on the inner side surface of the lower end portion of the vertical member 23. ing. That is, as shown in FIG. 1 and FIG. 2, the game ball B that has entered the warp inlet 22 flows downward in the warp passage 24 and then falls downward to constitute a longitudinal member that constitutes the case body C. It flows out on the shelf board main body 31 from the warp outlet 25 formed in the inner surface of 23.
[0018]
Further, the shelf body 31 has a belt-like shape, and at the central portion in the longitudinal direction, a game ball that rolls its upper surface in the left-right direction is guided to the central portion, and the start prize immediately below it is guided. A groove portion 31a is formed to facilitate winning in the mouth device 8, and a columnar retaining portion 31b having an outer diameter larger than the plate thickness of the general portion is integrally formed in the width direction at both ends in the longitudinal direction. It is the formed structure. On the other hand, as shown in FIGS. 4 and 7, an accommodation space portion 32 whose periphery is closed is formed immediately below the warp outlet 25 in the vertical member 23 constituting the case body C. A support slit portion 33 that communicates with the accommodation space portion 32 is formed horizontally on the inner surface. Both ends of the shelf board main body 31 are partially supported by the support slits 33, and a part from the supported part of the shelf board main body 31 to the edge in the longitudinal direction is accommodated in the accommodation space part 32. Has been placed. With this support structure, when the shelf body 31 is elastically deformed and its curved shape changes, as shown in FIGS. 4 to 6, the supported portion supported by the support slit portion 33. Is moved in the longitudinal direction, and both end portions that are greatly deformed are accommodated in the accommodating space portion 32 without interfering with each other, so that both ends are supported by the pair of support slit portions 33 regardless of the change in the curved shape. It is a supported structure.
[0019]
Next, the drive mechanism D for elastically deforming the shelf board body 31 will be described with reference to FIGS. 3, 4, and 7. An engagement pin 34 is integrally provided on the lower surface of the groove portion 31a at the center in the longitudinal direction of the shelf body 31 so as to protrude rearward (backward) from the edge in the width direction. The C back plate portion 26 is provided with an insertion hole 27 in the vertical direction for inserting the engagement pin 34 that moves up and down in response to the elastic deformation of the shelf body 31. On the back side of the case body C, a drive motor M with a brake is fixedly disposed so as to be biased from the insertion hole 27 to one side in the left-right direction, and the base end portion of the operating arm 36 is integrated with the drive shaft 35. Installed on. An engagement hole 37 is formed in the longitudinal direction at the distal end (free end) of the operating arm 36, and the engagement pin 34 is inserted into and engaged with the engagement hole 37.
[0020]
Here, the shelf body 31 is in a natural state of use (the state shown in FIG. 6) having the largest amount of elastic deformation, and its elastic deformation is caused by applying an upward external force to the central portion. The amount is changing.
[0021]
With the above configuration, when the drive shaft 35 of the drive motor M rotates by the set number of rotations, the operating arm 36 rotates integrally with the drive shaft 35 and is engaged with the engagement hole 37. The combination pin 34 is moved up and down. As a result, the shelf body 31 supported at both ends by the left and right support slits 33 is subjected to an upward external force at the center in the longitudinal direction, and the center of the shelf body 31 is connected to the drive motor. While moving up and down by an amount proportional to the number of rotations of the M drive shaft 35, both ends thereof are moved in the longitudinal direction while being supported by the pair of support slit portions 33. As a result, the shelf main body 31 is elastically deformed in a state where both ends are supported by the pair of support slit portions 33, and when the drive motor M is stopped, the shelf main body elastically deformed by the braking force. The deformed shape of 31 is maintained. In the example shown in FIGS. 4 to 6, the shelf main body 31 has a large degree of elastic deformation (elastic deformation amount) in this order.
[0022]
And the deformation | transformation state of the shelf main body 31 shown by FIG. 4 is a case where the amount of elastic deformation is the smallest, Comprising: The center part is lower than both ends, and it is a concave shape (valley shape). However, the height difference between the two parts is the smallest. In this state, the shelf body 31 is stationary in a state in which a restoring force (a downward force) for restoring the original shape shown in FIG. Here, when the game ball B released to the game area 4 and rolling in the area 4 flows out onto the shelf main body 31 through the warp inlet 22, the warp passage 24, and the warp outlet 25, FIG. As shown in (a), it rolls in the left-right direction on the shelf body 31. The deformation state of the shelf main body 31 shown in FIG. 4 is the smallest amount of deformation, and the difference in height between the both end portions and the central portion is small. The game ball B that rolls toward the warp outlet 25 has a low initial velocity. As a result, the rolling speed of the game ball B once becomes zero, and does not roll toward the opposite side. It is often released on the board surface from the front edge. As a result, there is a low probability that the game ball B released from the shelf main body 31 onto the board will win the starting prize opening device 8.
[0023]
Moreover, in the deformation | transformation state of the shelf main body 31 shown by FIG. 5, the elastic deformation amount, ie, the height difference of a both-ends part and a center part, is larger than the case where it shows by FIG. For this reason, as shown in FIG. 8 (b), the game ball B that has flowed out from the warp outlet 25 onto the shelf body 31 changes its direction at a position beyond its center and rolls in a pendulum shape ( Reciprocating), and the length from the central portion of the shelf main body 31 to the direction change position gradually decreases. And in the middle of the rolling, there is one that wins the start winning opening device 8 directly from the groove 31a in the center of the shelf main body 31, but as shown in FIG. Although it is a position deviated from the central portion, that is, the position directly above the start winning opening device 8, there are many that are released on the board surface at a position where the amount is smaller than the state shown in FIG. As a result, the probability that the game ball B released from the edge on the near side of the shelf main body 31 to the board surface wins the start winning opening device 8 is higher than the state shown in FIG.
[0024]
Further, in the deformed state of the shelf board main body 31 shown in FIG. 6, the elastic deformation amount is maximum, and the restoring force of the shelf board main body 31 is applied to the distal end portion of the operating arm 36. Not working. For this reason, as shown in FIG. 8C, the initial velocity of the game ball B that rolls from one warp outlet 25 toward the other warp outlet 25 becomes the highest. As a result, the game ball B reciprocally rolls on the shelf main body 31 in the left and right directions, and both the speed and the reciprocating stroke are rapidly reduced. It becomes easy to release on the board surface from the groove part 31a. As a result, the probability that the game ball released on the board will win the starting prize opening device 8 is higher than the state shown in FIG.
[0025]
As described above, the amount of elastic deformation of the shelf main body 31 increases sequentially due to the restoring force of the shelf main body 31, and the operating arm 36 receives the restoring force of the shelf main body 31. . In contrast, when the amount of elastic deformation of the shelf main body 31 is sequentially reduced, that is, when the state shown in FIG. 6 is changed to the state shown in FIG. 4 through the state shown in FIG. This rotational force (torque) elastically deforms the shelf board body 31 against the restoring force of the shelf board body 31.
[0026]
For this reason, the amount of elastic deformation of the shelf main body 31 changes in multiple stages, whereby the game balls B that have flowed out (released) from the warp outlet 25 onto the shelf main body 31 are arranged in the left-right direction (the length of the shelf main body 31). ), The winning probability for the start winning opening device 8 immediately below the groove portion 31a in the central portion in the longitudinal direction of the shelf body 31 also changes stepwise. As described above, the rolling state of the game ball B on the shelf board body 31 can be changed in stages by changing the amount of elastic deformation of the shelf board body 31 made of an elastic material in multiple stages. Therefore, the monotonous change of the rolling state is eliminated, and the fun of the game is increased.
[0027]
Moreover, in the said embodiment, the winning probability with respect to the start winning opening apparatus 8 is the lowest in the state shown by FIG. 4, and also in this state, the shelf main body 31 becomes concave and becomes a gentle valley shape upwards. is doing. On the other hand, the operating arm 36 is further rotated clockwise to apply an external force upward to the central portion of the shelf board body 31, and is deformed into a gentle mountain shape with an upward projection. If the possibility that a game ball will drop from the vicinity of both ends in the longitudinal direction of the shelf main body 31 greatly deviated in the left-right direction from directly above the start winning opening apparatus 8 is, the winning probability for the starting winning opening apparatus 8 is as shown in FIG. It can be made lower than the case of the shape of the shelf main body 31 shown in FIG.
[0028]
Moreover, although the said embodiment is an example in which the shelf main body 31 changes in three steps, it can also be changed more many times by control of rotation / stop of the drive motor M.
[0029]
The timing of changing the shape of the shelf main body 31 can be arbitrarily set regardless of the gaming state, but depending on the change of the gaming state, for example, when the probability changes and the normal time, the former In this case, by changing the shape of the shelf main body 31 so as to increase the elastic deformation amount, the winning probability for the start winning opening device 8 is increased, and the symbol changing opportunities of the special symbol display device 7 are increased. It is preferable. It is preferable that the shape of the shelf main body 31 is changed corresponding to the gaming state, that is, the start timing of the drive motor M is controlled by the main control board. Thereby, the player's expectation for the big hit can be increased.
[0030]
Further, when the shape of the shelf board main body 31 is changed, the timing of changing the shape of the shelf main body 31 is linked with the display effect of the special symbol display device 7, for example, when a specific character appears, the elasticity of the shelf board main body 31 is changed. In the case where control is performed such that the amount of deformation is increased and the winning probability for the start winning opening device 8 is increased, it is preferable to control by the symbol control board.
[0031]
Furthermore, the drive mechanism that changes the curved shape of the shelf body 31 only needs to have the output unit reciprocate linearly. In addition to the above embodiment, a piston crank mechanism that converts rotational motion into reciprocating linear motion, It is also possible to use a cam mechanism or the like that converts a revolving motion into a reciprocating linear motion.
[0032]
【The invention's effect】
A shelf device for a gaming machine according to the present invention is formed of an elastic material, and a shelf body that is supported so that both ends in the left-right direction can move in the same direction, and the shelf body are in a substantially horizontal state. The drive mechanism for elastically deforming between the presenting position and the position exhibiting the concave curve in the center downward direction, the curved shape of the shelf body is changed in multiple stages by the drive mechanism. Thus, the rolling mode of the game ball that rolls on the upper surface differs depending on the curved shape of the shelf board body. As a result, the rolling mode of the game ball rolling on the upper surface thereof is changed in multiple stages due to the change in the curved shape of the shelf main body, and the game ball is dropped and released from the central portion in the left-right direction of the shelf main body. The probability of playing changes gradually, and the fun of the game increases.
