Description

  The present invention relates to a gaming machine power supply device provided with an operation unit or the like according to a change in setting of the winning probability of jackpot, and a gaming machine equipped with the gaming machine power supply device, and in particular, eliminates an unauthorized operation on the operation unit. The present invention relates to a gaming machine power supply device provided with a cover and a gaming machine equipped with the gaming machine power supply device.

  Some gaming machines such as slot machines and pachinko machines have a so-called setting probability changing function, which is a function for changing a winning probability for winning a big hit by operation.

All or a part of the operation unit for changing the winning probability is arranged in a power supply device that supplies power to each part in the gaming machine, for example, a power switch or a setting key switch. Then, after the setting key corresponding to the setting key switch (cylinder part) is inserted and rotated to turn it on, the power switch is turned on so that the setting of the gaming machine can be changed. ing.
The operation unit related to the setting change of the winning probability is covered by a lockable front door of the gaming machine, and is normally inoperable. However, in recent years, there are frequent acts of performing unauthorized operations by inserting a piano wire, a cell, or the like through a gap in the front door to access the operation unit.

For the purpose of eliminating such unauthorized access to the operation unit, a defensive measure has been conventionally taken.
For example, Patent Document 1 proposes a technique of covering an operation unit of a gaming machine power supply device with a cover biased in a closing direction. This technology further includes a lock mechanism that manually locks the cover so that it cannot be opened and closed.
Patent Document 2 also proposes a technique for covering the operation unit with a cover that is also urged in the closing direction, and this technique employs a lock mechanism that automatically locks when the cover is released from the open state. Yes.

JP 2004-65493 A JP 2008-228944 A

However, the techniques described above have had the following adverse effects.
Since the lock mechanism described in Patent Document 1 requires a lock operation, it cannot prevent forgetting to close the cover.
On the other hand, the lock mechanism described in Patent Document 2 automatically locks the cover when it is released, so that it is possible to prevent forgetting to close and to make the unlocking operation complicated by using two actions for unlocking. Although the unauthorized access can be suppressed, there is a problem that the structure is complicated, the number of parts is increased, and the product cost is increased.

There are various types of gaming machines such as pachinko machines, slot machines, arrange balls, sparrow balls, etc. In this embodiment, the power supply device for gaming machines of the present invention is applied to slot machines using medals as gaming media. The case will be described.

[Slot machine]
As shown in FIGS. 1 and 2, the slot machine 1 of the present embodiment can acquire game media (medals) by rotating a plurality of reels 71a, 71b, 71c, and is divided into six stages in advance. This is a spinning-reel game machine having a setting probability changing function that can change the jackpot winning probability set in any stage.
The slot machine 1 includes a housing 1b that opens on the front side for storing necessary machines, devices, and the like, and a front door 1a that covers the front side of the housing 1b so as to be opened and closed.

  The front door 1a is a door that is attached to the housing 1b through a hinge 1c so as to be opened and closed. The front door 1a has a medal slot 2 for inserting medals, a start lever 3 for starting rotation of each reel 71, A plurality of operation means such as three stop buttons 4a to 4c for stopping each rotating reel 71, a MAXBET button 5a and a 1BET button 5b for inserting a medal stored (credited) into the game by a pressing operation; The front portion of the slot machine 1 is provided with a payout number display section 6 for displaying any number of stages (1 to 6) in a state where the set probability can be changed and displaying the number of payout medals in other states. Is configured.

  The back of the front door 1a is provided with a selection switch (not shown) capable of selecting any one of six winning probabilities in a state where the setting probability can be changed, and a payout number display portion. The set probability can be selected while visually recognizing any number of steps displayed in FIG.

In the center of the housing 1b, reels 71a, 71b, 71c, a motor (not shown) that rotatably supports each reel 71, a sensor that detects a rotational position, and the like are provided.
A medal payout device 8 and a power supply device 9 for storing and paying out medals are provided at the lower part of the housing 1b, and a substrate case 10 is attached to the upper rear surface of the housing 1b.

  The power supply device 9 is configured as a power supply device for a gaming machine according to the present invention that generates and supplies power suitable for each part in the slot machine 1, and an operation unit such as a power switch 9b for turning the power ON / OFF (ON / OFF). Is provided (see FIG. 3).

The board case 10 accommodates a so-called main board 10a that controls the progress of the slot machine game by controlling the devices such as the reels 71 and the medal payout device 8 based on the signals from the respective operating means. At the same time, a setting key unit 11 having a setting key switch for changing the setting probability by a key operation is mounted.
The substrate case 10 includes two cases formed of a colorless and transparent synthetic resin (for example, polycarbonate), and the main substrate 10a is accommodated so as to be sandwiched between these cases.

The main board 10a is configured as a computer including a CPU (Central Processing Unit), storage means such as ROM and RAM, IC components such as an I / O interface, resistors, capacitors, transistors, and the like.
In the ROM, a control program and data for controlling the slot machine 1 are stored, and in this data, a big hit lottery data table to be compared with random numbers is set in an internal lottery performed for each game.

  The jackpot lottery data table quantifies the winning range for lottery targets such as bonus combinations that win big hits, small roles where medals are paid out, re-playing roles that can be played next time without inserting medals, and losers. In the data table, it is compared with a random number acquired at the timing of operating the start lever 3, and it is made to hit a lottery object in the winning range to which the random number belongs. That is, it is a data table in which the winning probability of each lottery object changes by changing the winning range of each lottery object.

  In the slot machine 1 according to the present embodiment, six big hit lottery data tables having different winning ranges (winning probabilities) such as bonus combinations and small combinations are stored in the ROM, and the power switch 9b is turned on for the main board 10a. When the ON signal is received from the setting key switch, the setting probability is changed. In this state, an arbitrary data table can be selected by operating the above-described selection switch, and a change to the selected setting probability is determined by operating the start lever 3, and the setting key switch is turned OFF. By returning, the selected jackpot lottery data table is used as a reference table at the time of internal lottery.

That is, the power switch 9 a provided in the power supply device 9, the setting key switch provided in the setting key unit 11, the selection switch, and the start lever 3 are the operation units related to the change setting of the winning probability of the present invention. Further, since the setting change of the winning probability is effective only when the power is turned on, the power switch 9a is particularly regarded as an important operation unit in changing the setting of the winning probability.
Therefore, the power supply device 9 includes a cover 92 according to the present invention that covers the power switch 9a in the closed state so that it cannot be operated (described later).

The slot machine 1 configured as described above is controlled as follows by the main board 10a, and the slot machine game proceeds.
First, when a player inserts a medal from the medal insertion slot 2 and operates the start lever 3, the main board 10a controls to rotate each reel 71 and refers to the set big hit lottery data table. The internal lottery that draws bonuses, small roles, etc. is performed, and based on the timing when each stop button 4 is pressed, stop control of each rotating reel 71 so as to stop at a combination of symbols according to the winning result I do.
Further, the main board 10a determines a combination of symbols to be stopped and displayed on each reel 71, and controls the medal payout device 8 to pay out a predetermined number of medals when the combination of the predetermined symbols is reached.

[Power supply unit]
Next, a detailed configuration of the power supply device 9 according to the present invention will be described with reference to FIGS.
3 and 4 are perspective views of the power supply device 9 as viewed from the left side. FIG. 3 shows an open state in which the cover 92 is opened, and FIG. 4 shows a closed state in which the cover 92 is closed.
As shown in each drawing, the power supply device 9 of this embodiment is formed in a housing shape by processing a steel plate, and a device main body 9a in which a power supply board or the like (not shown) is built, and is attached to the device main body 9a. The power switch 9b, which is one of the operation units related to the setting change, and other operation units are arranged so as to be surrounded by the cover unit 90.
As other operation units, for example, a stop presence / absence switch for setting presence / absence of stop of the slot machine 1 (slide switch corresponding to “stop” in FIGS. 3 to 6), in order to collect medals during maintenance, An automatic settlement switch (a slide switch corresponding to “automatic settlement” in FIGS. 3 to 6) for setting whether or not to automatically pay out medals to the tray of the slot machine 1 is provided.

  The cover unit 90 includes a pedestal 91 and a cover 92 supported by the pedestal 91 so as to be openable and closable, and is screwed to the apparatus main body 9a with screws 9c. The cover unit 90 is mounted so as to face the front side opening of the housing 1b (see FIG. 2).

The pedestal 91 is a plate-like member formed of a predetermined synthetic resin (for example, polycarbonate), a support shaft 911 that supports the cover 92 so as to be rotatable and vertically movable along a rotating axial direction, and a cover. 92, an engaging portion 913 that engages with the engaging piece 923, an enclosing rib 914 that surrounds the side face of the power switch 9b facing the outside, and a recess 915 into which the outer edge rib 92b of the cover 92 is fitted. ing.
The surrounding rib 914 is formed with a height that exceeds the range in which the operation end of the power switch 9b can be moved by operation. Further, a space 915a that is flush with the concave portion 915 is provided above the concave portion 915 so that the cover 92 can be moved upward (the other side) along the axial direction while being closed.

Further, a torsion coil spring 90a, which is an example of an urging means, is provided at the lower right portion of the base 91. The torsion coil spring 90a is wound around a shaft obtained by extending the support shaft 911, and one end thereof is locked to the cover 92 (see FIGS. 7 to 9). The torsion coil spring 90a acts to urge the cover 92 in the closed state and along the support shaft 911 downward (one direction side).
Thus, since both are realized by the one torsion coil spring 90a without providing the biasing means for closing the cover 92 and the biasing means for the lower side, the cost can be reduced.

  The cover 92 is a concave member that covers the power switch 9b formed of a predetermined synthetic resin (for example, polycarbonate). The cover 92a covers the front surface of the power switch 9b in a closed state, and an outer edge rib 92b that surrounds the side surface of the power switch 9b. The bearing 921 is loosely fitted to the support shaft 911 so as to be rotatable and vertically movable along the rotating axial direction, the engagement piece 923 is engaged with the engagement portion 913, and the cover 92 is opened. A handle 924 is formed for operation.

In the present embodiment, the support shaft 911 and the bearing 921 constitute a hinge portion 90b according to the present invention, and the hinge portion 90b is formed to be positioned on the right side of the cover unit 90. Thereby, the left side of the cover 92 is opened. On the other hand, since the front door 1a has the hinge 1c on the left side, the right side is opened (see FIG. 2).
Thus, by making the opening / closing direction of the cover 92 different from the opening / closing direction of the front door 1a, even when both are opened, the access path to the power switch 9b is bent, and unauthorized operation is performed. Can be difficult.

With this configuration, the power switch 9b is protected from unauthorized access as follows.
When the power switch 9b is a seesaw type switch, for example, the surrounding rib 914 is formed higher than the apex of the operation end (triangular portion) of the seesaw type switch. The act of operating 9b can be prevented.
Further, in the closed state of the cover 92, the outer edge rib 92b is inserted into the recess 915, so that the foreign substance intrusion path from the side surface of the cover 92 is U-shaped, making it difficult for the foreign substance to enter. .

Further, the cover unit 90 includes a slide lock 90c that locks the cover 92 so that it cannot be opened and closed by the engagement of the engagement piece 923 and the engagement portion 913.
Specifically, the slide lock 90c includes an engagement piece 923 and an engagement portion 913. The engagement portion 913 has a groove portion 913a into which the engagement piece 923 is fitted, and the engagement piece 923 is guided to the groove portion 913a. A slope 913b is provided.

With such a configuration, the cover 92 in the closed state is configured such that the engagement piece 923 is fitted into the groove portion 913a (the engagement piece 923 and the engagement portion 913 are engaged) as shown in FIG. 92 is locked so that it cannot be opened and closed.
In the closed state, when the cover 92 is moved upward (on the other side) along the support shaft 911 until the engagement piece 923 comes out of the groove 913a in the closed state (the engagement piece 923, the engagement portion 913, Can be released (see FIG. 8).
That is, the slide lock 90c operates as the rotation restricting means according to the present invention, and is engaged with the engagement piece 923 when the cover 92 is positioned on the lower side (one side) along the support shaft 911 in the closed state. The cover 92 is moved along the support shaft 911 until the cover 923 is engaged, the rotation of the cover 92 in the opening direction is prevented, and the engagement piece 923 and the engagement portion 913 are disengaged. When the cover 92 is moved upward (the other side), the cover 92 is allowed to rotate in the opening direction, and the cover 92 can be opened as shown in FIG.

Further, since the cover 92 is biased downward (one side) by the torsion coil spring 90a, the cover 92 is always locked in the closed state. Therefore, in order to open the cover 92, it is necessary to apply an external force that moves the cover 92 upward (the other side) along the support shaft 911 against the urging force of the torsion coil spring 90a.
For this reason, in the case of a long object such as a piano wire or a cell inserted from the gap of the front door 1a, the force to move the cover 92 upward cannot be transmitted to the cover 92, so that unauthorized access can be suppressed.

Next, the holding means according to the present invention will be described with reference to FIGS.
5 and 6 are a perspective view of the power supply device 9 viewed from the right side and an enlarged perspective view of the hinge portion 90b. FIG. 5 is a perspective view of the cover 92 in the closed state and located on the lower side. FIG. 6 is a perspective view showing an open state in which the cover 92 is slightly opened.
As shown in each figure, the cover 92 includes a rotating piece 922 protruding in a direction orthogonal to the support shaft 911 on the hinge portion 90b side, and the support shaft 911 protrudes in the same direction as the rotating piece 922. Guide pieces 912 are provided, and in the open state, they are engaged as follows to operate as the holding means of the present invention.

  Specifically, as shown in each drawing, the guide piece 912 is in a closed state and is in contact with a rotating piece 922 (back surface) located on the lower side, and is closed and located on the upper side. A contact surface 912a that is not in contact with the rotating piece 922 (back surface), and a rotating piece 922 that is in the open state excluding the closed state and located on the upper side (bottom surface: lower side wall surface [one-way side wall surface]) ) And a slidable contact surface 912b.

  With such a configuration, the cover 92 that is in the closed state and located on the lower side is moved upward, so that the rotating piece 922 (back surface) and the contact surface 912a are brought into a non-contact state, and the cover By rotating 92 in the opening direction (open state excluding the closed state), as shown in FIG. 6, the rotating piece 922 (bottom surface) and the sliding contact surface 912b are in sliding contact.

  In this slidable contact state (open state excluding the closed state), the cover 92 is biased downward by the torsion coil spring 90a, but the guide piece 912 resists this biasing force and moves the rotary piece 922 upward. (Holding means). Therefore, in order to open the cover 92 after applying an external force that moves the cover 92 located in the closed state on the lower side upward, only the external force that rotates the cover 92 in the opening direction is used. It turns out that it is only necessary to act. That is, after the cover 92 is moved upward, the cover 92 can be opened only by an external force in the opening direction.

  Further, in this sliding contact state (open state excluding the closed state), the cover 92 is urged in the closing direction by the torsion coil spring 90a. Therefore, when the external force applied to the cover 92 is eliminated, the cover 92 returns to the closed state while the guide piece 912 holds the rotating piece 922 on the upper side, and the sliding contact state is released in this closed state, and the coil spring 90a. Is moved downward by the downward biasing force. As a result, the cover 92 is in a locked state in which the engagement piece 923 is fitted into the groove 913a. That is, when the hand is released from the cover 92 in the open state, the cover 92 is not only closed but also automatically locked.

  In addition, although the contact surface 912a and the sliding contact surface 912b of the guide piece 912 in the above-described embodiment are formed so as to intersect at a substantially right angle, it can also be connected by an arc (R). When crossing at a right angle, the operating path when the cover 92 on the lower side is moved upward and then further rotated in the opening direction is a right angle, but when connected by an arc (R), the operating path becomes an arc. The operation becomes smoother because of the drawing, and the operation burden on the game staff such as a store clerk can be reduced.

In addition, when the arcs (R) are connected, if the hand is released from the cover 92 in the open state, the cover 92 moves downward before reaching the closed state, and the engagement piece 923 becomes the groove portion. There is a risk that the 913a will not be fitted. However, the slope 913b formed in the engaging portion 913 holds the engaging piece 923 to be moved downward from the lower side, and guides the engaging piece 923 to the groove portion 913a (second second). Holding means).
The slope 913b is formed as an inclined surface that is inclined upward toward the groove portion 913a, and the engaging piece 923 is guided by the groove portion 913a while the bottom surface thereof is in sliding contact with the slope 913b.

Furthermore, the guide piece 912 and the turning piece 922 operate as the second turning restricting means according to the present invention.
Specifically, as is clear from FIG. 5, the rotating piece 922 that is in the closed state and located on the lower side is in contact with the contact surface 912 a of the guide piece 912.
For this reason, the cover 92 that is in the closed state and located on the lower side is covered with the cover piece 912 in a state where the turning in the opening direction is hindered by the guide piece 912, that is, the engagement between the guide piece 912 and the turning piece 922. Reference numeral 92 denotes a locked state that cannot be opened and closed (second rotation restricting means).
This lock can be released by moving the cover 92 upward as in the case of unlocking the slide lock 90c.
Therefore, even if the slide lock 90c is eliminated, it can be understood that the cover 92 in the closed state is in the locked state due to the engagement between the guide piece 912 and the rotating piece 922.
As described above, the guide piece 912 and the turning piece 922 have a simple structure in which the guide piece 912 and the turning piece 922 are projected from the hinge portion 90b and the support shaft 911, respectively, but operate not only as holding means but also as turning restriction means. There is no need to install them separately, and the cost can be reduced.

The opening / closing operation of the cover 92 of the cover unit 90 according to the present embodiment configured as described above will be described with reference to FIGS.
FIG. 7 shows the cover unit 90 located on the lower side with the cover 92 closed, (a) is a left side view, (b) is a front view, and (c) is a right side view. 8 shows the cover unit 90 located on the upper side with the cover 92 closed, (a) is a left side view, (b) is a front view, and (c) is a right side view. is there. FIG. 9 is a right side view of the cover unit 90 with the cover 92 in the closed state.

As shown in FIG. 7, in the closed state, the power switch 9b is covered with a cover 92 so as not to be operated, and is protected from unauthorized access.
Since the cover 92 is closed and biased downward by the torsion coil spring 90a, the closed state is maintained unless any external force is applied. When the cover 92 is in the closed state and positioned on the lower side, the engagement piece 923 is not only fitted into the groove portion 913a, but the rotation piece 922 is in contact with the guide piece 912. Rotation in the direction is impeded. That is, the cover 92 is locked so that it cannot be opened and closed.

  In this state, as shown in FIG. 8, when the handle 924 is picked and an external force in the A direction (upper side) is applied to the cover 92, the engaging piece 923 is removed from the groove 913a and rotated. The piece 922 and the guide piece 912 are not in contact with each other, and the cover 92 is allowed to rotate in the opening direction.

  Further, when an external force in the opening direction is applied to the cover 92, the rotating piece 922 and the guide piece 912 are brought into a sliding contact state as shown in FIG. 9, and the cover 92 is urged downward by the torsion coil spring 90a. However, since the guide piece 912 holds the rotating piece 922 on the upper side against this biasing force, the cover 92 can be opened by applying only an external force that rotates in the opening direction. It has become. Note that the rotating piece 922 of the present embodiment has an arcuate surface in contact with the support shaft 911, and operates as a bearing (see FIG. 5).

  In the open state, the front surface of the power switch 9b is exposed to the outside. A game hall clerk such as a store clerk can perform an ON / OFF operation related to a setting change operation of the winning probability with respect to the power switch 9b while an external force in the opening direction is applied to the cover 92.

When the hand is released from the cover 92 in this open state, the cover 92 returns to the closed state by the urging force of the torsion coil spring 90a.
At this time, the cover 92 returns to the closed state while being held upward by the guide piece 912. In this closed state, the holding by the guide piece 912 is released, and the cover 92 moves downward by the downward biasing force of the coil spring 90a. . Simultaneously with the downward movement, the engaging piece 923 is fitted into the groove portion 913a, and the rotating piece 922 comes into contact with the guide piece 912, and the cover 92 returns to the locked state again.
As described above, the cover 92 always returns to the closed state and the locked state in the state where no external force is applied, so that not only forgetting to close but also forgetting to lock can be prevented.

  As described above, according to the power supply device 9 according to the present embodiment, forgetting to lock and eliminating unauthorized access to the operation unit can be realized with a simple structure.

  The gaming machine power supply device of the present invention and the gaming machine equipped with this gaming machine power supply device have been described with reference to the preferred embodiments, but the gaming machine power supply device according to the present invention and this gaming machine power supply are described. It is needless to say that the gaming machine including the device is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention.

  For example, in the present embodiment, the holding unit according to the present invention is configured by the rotating piece 922 and the guide piece 912, but may be configured by the locking piece 923 and the slope 913b. In this case, it is sufficient to form the slope 913b so as to be always positioned on the lower side in the rotation trajectory of the locking piece 923.

In the present embodiment, the rotation direction of the cover is the horizontal direction, but it may be the vertical direction. In this case, the movement direction along the axial direction of the cover is the left-right direction.
Further, in this embodiment, only the power switch 9b is provided in the power supply device 9. However, other operation units related to the setting change of the winning probability such as a setting key switch and a selection switch are provided in the power supply device, and these are provided as one cover. The whole may be covered with 92, or each may be covered with an independent individual cover 92.

  Further, in the present embodiment, only the power switch 9b, which is the operation unit related to the setting change of the winning probability, is covered with the cover 92. However, a stop presence / absence switch (in FIG. 3 to FIG. 6), which is another operation unit. It is also possible to adopt a configuration in which a cover 92 covers a slide switch corresponding to “stop” and an automatic settlement switch (a slide switch corresponding to “automatic settlement” in FIGS. 3 to 6). In this case, in each of FIGS. 3 to 9, the cover 92 may be expanded in the vertical direction so that these switches can be covered, or a dedicated cover separate from the cover 92 may be provided. good.

  The present invention can be applied to a gaming machine having a winning probability setting change function.
