As described above, generally, in a gaming machine such as a slot machine, a front door (door body) is provided to be openable/closable with respect to a housing (support member) from the viewpoint of maintenance and the like. Therefore, the gaming machine is provided with a locking device so that a person other than the clerk cannot open the front door without permission. Examples of such a locking device include a cylinder lock that is operated by using a dedicated key, a plurality of hook members that are respectively engageable with and disengageable from a plurality of locked portions provided in the housing, and a cylinder that uses a key. It is known that a slide rod is provided which interlocks a plurality of hook members according to an unlocking operation of a lock. In the locked state, each hook member engages with the corresponding locked portion, so that the front door cannot be opened from the housing. On the other hand, by unlocking the cylinder lock with a dedicated key, each hook member simultaneously disengages from the locked portion via the sliding rod, and the front door can be opened.

In recent years, in gaming halls, for example, illegal actions such as illegally unlocking the front door during business hours and illegally operating or exchanging the control device provided inside the housing have been conducted. Sometimes it is done. Such unauthorized unlocking is usually performed by inserting a wire material such as a wire through a gap between the front door and the housing, hooking the wire material on a hook member of the locking device, and moving the wire material in the unlocking direction. When an unauthorized unlocking operation is performed on any one of the hook members, the operation is transmitted to the other hook members through the sliding rod, and all the hook members are interlocked and disengaged from the locked portion. , The front door can be opened.

On the other hand, for example, when an unauthorized unlocking operation is performed on any one of the hook members, the operation of the hook member corresponding to the unauthorized unlocking operation is performed by the other unlocking operation. Some have a mechanism for preventing transmission to the hook member (see, for example, Patent Document 1).

However, in the above-mentioned conventional technique, the plurality of hook members are provided vertically separated from each other. In other words, a plurality of targets on which the wire rod is hooked when the above-mentioned illegal unlocking operation is attempted are in a positional relationship. For this reason, it is relatively easy to hook the wire rod onto the plurality of hook members, and the plurality of hook members may be simultaneously displaced in the unlocking direction to unlock the front door.

Incidentally, such a problem is not limited to a spinning-roller gaming machine such as a slot machine, but is a problem that also applies to other gaming machines such as a pachinko machine having a locking mechanism for locking the door body and the support member.

Hereinafter, each means suitable for solving the above-mentioned problems will be described by dividing them into items. In addition, the action and effect peculiar to the corresponding means will be additionally described as needed.

Means 1. A door body that is openably and closably supported with respect to the support member,
A gaming machine comprising a locking mechanism for locking the door member to the support member,
The locking mechanism is
A locking device provided on one of the support member or the door body, and an engaged means provided on the other,
The locking device is
A lock member operated by a key,
In association with the operation of the lock member, at least a hook portion lockable side specific position and a hook portion displaceable between the hook portion unlocking side specific position,
The engaged means is
At least a movable engaging portion that is displaceable between the engaging portion locking side specific position and the engaging portion unlocking side specific position,
When the hook portion and the movable engaging portion are in an engaged state, a locked state in which opening of the door body is regulated,
By being in a non-engagement state with the hook portion and the movable engagement portion, it is in a unlocked state in which the opening of the door body is allowed
When closing the door body with respect to the support member without using the key, at least the movable engaging portion is in a state of being displaced to the engagement portion unlocking side specific position side, so that the door body A relative displacement amount of a predetermined amount or more between the hook portion and the movable engaging portion required for closing the
In the locked state, when there is a specific operation of the lock member by the key, at least the hook portion is displaced to the hook portion unlocking side specific position side to be in the disengaged state. A relative displacement amount of a predetermined amount or more between the hook portion and the movable engaging portion required for
In the locked state, and in the state in which there is no specific operation of the lock member by the key, a relative displacement of a predetermined amount or more between the hook portion and the movable engagement portion required to be in the disengaged state. A gaming machine comprising a movable engaging portion restricting means for restricting a displacement of the movable engaging portion toward the engaging portion unlocking side specific position side by a predetermined amount or more so that the amount cannot be obtained. ..

According to the above-mentioned means 1, by providing the movable engaging portion restricting means, when an external force is directly applied to the movable engaging portion by a wire or the like in a locked state without using a key, that is, an illegal unlocking operation. When the operation is performed, the displacement of the movable engaging portion by a predetermined amount or more is restricted, and the engagement state between the movable engaging portion and the hook portion is maintained. Therefore, the opening of the door is not allowed. On the other hand, if at least the hook portion is displaced in the unlocking direction by operating the lock member with the key and the relationship between the hook portion and the movable engaging portion is relatively displaced by a predetermined amount or more, both are not The engaged state is established and the opening of the door is permitted. Therefore, if the movable engaging portion is displaced in the unlocking direction using a wire or the like and the engaging state with the hook portion is to be illegally released, at least the regulation by the movable engaging portion regulating means is released. After or at the same time as the operation, it is necessary to perform two types of operations such as a displacement operation in the unlocking direction of the movable engaging portion. For this reason, it is necessary to perform a complicated operation such as hooking a wire rod or the like on a plurality of members provided in proximity such as the movable engaging portion and the movable engaging portion restricting means for restricting the movable engaging portion. It will be difficult. As a result, the defense performance against unauthorized unlocking using a wire or the like is significantly improved. When the door is closed without using a key, at least the movable engaging portion is displaced in the unlocking direction so that a predetermined amount or more between the hook portion and the movable engaging portion required to close the door is provided. The relative displacement of is obtained. That is, even if the hook portion is not displaced, the movable engaging portion is displaced, so that the door body can be closed. In other words, the door can be closed without using the key (at least without performing the specific operation), which is highly convenient.

The same applies to the following means, but the number of hooks and movable engaging portions corresponding thereto is not limited to one, and a plurality of hooks may be provided.

Further, examples of the lock member include a cylinder lock in which a key is inserted and rotated. In this case, the operating portion operated by the key is composed of a lock shaft rotatably provided, an engagement piece (cam plate) fixed to the lock shaft, and the like. Of course, the lock member is not limited to the cylinder lock, but may be operated by using a key such as a card key.

Further, the term “engagement (engagement state)” of the hook portion and the movable engagement portion refers to the hook portion when the door body is moved at least in a direction of opening the door body (for example, forward direction) in a closed state of the door body. And the movable engaging portion is in contact with each other, and the movable engaging portion and the movable engaging portion are in a positional relationship of restricting the opening of the door body. Therefore, in the "engagement" of the hook portion and the movable engaging portion, not only when the two are always in contact, but by providing a predetermined clearance (play) between them in consideration of operability, In the closed state of the door body, the case where both are separated is also included. For example, a predetermined clearance is set between the hook portion and the movable engaging portion that are in the engaged state in the front-rear direction that is the opening and closing direction of the door body, and when the door body is in the closed state, the hook portion and the movable engaging portion are engaged. Although the parts are not in contact with each other in the front-rear direction, when the door body is moved so as to be opened, it is sufficient that both parts engage with each other.

Further, the "non-engaged state" of the hook portion and the movable engaging portion means a positional relationship in which the hook portion and the movable engaging portion do not come into contact with each other when the door body is moved in the opening/closing direction, or a door body which is in contact with the door portion. Indicates a state in which the position can be opened. That is, the "relative displacement of a predetermined amount or more" between the hook portion and the movable engaging portion required to open and close the door means that the two are not in the state (engagement state) in which they are located at their locking side specific positions. A relative displacement amount of a predetermined amount or more until reaching the engaged state. For example, the hook portion and the movable engaging portion engage with each other in the front-rear direction, which is the opening and closing direction of the door body, and when the door body opens and closes, the engaging portions of the hook portion and the movable engaging portion each have at least the vertical direction (the door body). In the configuration in which the two are displaced in the direction orthogonal to the opening/closing direction, the relative displacement amount of a predetermined amount or more in the vertical direction from the engagement state to the non-engagement state is the above-mentioned “relative displacement amount of a predetermined amount or more”. It corresponds to "quantity".

Means 2. The movable engaging portion restriction means,
A first state in which the displacement of the movable engaging portion is restricted in the locked state,
At least when the door body is closed with respect to the support member, the hook portion and the movable engaging portion can be changed into a second state that allows the hook portion and the movable engaging portion to be in an engaged state. The game machine described.

According to the above means 2, the door can be smoothly closed without being disturbed by the movable engaging portion restricting means, and convenience is improved.

Means 3. The movable engaging portion restriction means,
A restriction member displaceable between the first position and the second position,
A regulating member urging means for urging the regulating member toward the first position,
When the restriction member is in the first position, the restriction member is in the first state,
A configuration in which the restriction member is in the second state by taking the second position,
When closing the door with respect to the support member, at least the movable engaging portion is displaced to the engaging portion unlocking side specific position side by contact between the hook portion and the movable engaging portion. Along with
The restriction member is
When the movable engaging portion displaced to the engagement portion unlocking side specific position side comes into contact, it is displaced to the second position side against the urging force of the regulating member urging means,
When the hook portion and the movable engaging portion are in an engaged state, the movable engaging portion is brought into a non-contact state, and returns to the first position. ..

According to the above means 3, by closing the door body, the movable engaging portion restricting means is automatically changed in state, the hook portion and the movable engaging portion are allowed to be in the engaged state, and both are When engaged, the displacement of the movable engaging portion is restricted. Therefore, when the door is closed, it is not necessary to perform any special operation, and convenience can be improved. In addition, such an action and effect is obtained by at least the movable engagement by the contact between the hook portion and the movable engagement portion when the door is closed with respect to the support member of the means 3. In the case of closing the door with respect to the support member, at least the movable engaging portion unlocks the engaging portion in place of the configuration in which the portion displaces toward the engaging portion unlocking side specific position side. It is also possible to obtain a configuration in which the hook portion and the movable engaging portion are in contact with each other while being displaced to the side specific position side.

In order to realize the above configuration, the following configurations can be adopted. For example, the tip of the hook portion is tapered in a substantially triangular shape, and when the door is closed, the inclined portion of the hook portion first comes into contact with the movable engaging portion. Further, by closing the door body, the movable engaging portion is displaced in the unlocking direction against the biasing force of the biasing means such as the coil spring. Then, when the hook portion gets over the movable engaging portion, the movable engaging portion returns to its original position by the urging force of the urging means, becomes engaged with the hook portion, and is locked.

Further, when the direction in which the regulating member is displaced from the first position to the second position is different from the direction in which the movable engaging portion is displaced toward the engaging portion unlocking side specific position side, it is possible to perform fraudulent acts by the wire rod or the like. When performing, a complicated operation such as operating a wire rod hooked on the both in different directions must be performed, and an unauthorized unlocking operation becomes more difficult.

Means 4. In the locked state, and in the state in which there is no specific operation of the lock member by the key, a relative displacement of a predetermined amount or more between the hook portion and the movable engagement portion required to be in the disengaged state. In order not to obtain the amount, a hook portion restricting means for restricting the displacement of the hook portion to the unlocking side specific position side by a predetermined amount or more is provided,
The gaming machine according to any one of means 1 to 3, wherein when a specific operation of the lock member is performed by the key, the regulation by the hook portion regulation means is released.

According to the above-mentioned means 4, by providing the hook portion restricting means, if an external force is directly applied to the hook portion by a wire or the like in the locked state without using a key, that is, an illegal unlocking operation is performed. In this case, the displacement of the hook portion by a predetermined amount or more is restricted, and the engagement state between the hook portion and the movable engagement portion is maintained. Therefore, opening of the door body is not allowed. On the other hand, when the unlocking operation is performed using the key, the hooks are displaced by a predetermined amount or more in accordance with the operation, and the both are disengaged, and the opening of the door body is allowed. As described above, in the configuration provided with both the hook portion restricting means and the movable engaging portion restricting means, it becomes difficult to perform the illegal unlocking operation. Therefore, the synergistic effect of the both aims to further improve the defense performance against the illegal unlocking. be able to.

In addition, in the structure provided with the above-mentioned hook part regulation means, when trying to close a door without using a key, if the engaged means (engagement part) is fixed, the hook part and the engaged part are engaged. Since the collision with the coupling means causes a comparatively large impact, there is a possibility that a defect such as deformation or breakage of the hook portion or the engaged means may occur. In this respect, since the movable engaging portion is configured to be displaced in the present means, even if the displacement of the hook portion is restricted, a predetermined amount or more between the hook portion and the movable engaging portion is required. Since the relative displacement amount of is secured, the above-mentioned problem is unlikely to occur. Therefore, when the door is closed, there is no need to perform a locking operation using a dedicated key, and convenience is improved.

Means 5. The locking device includes a transmission member that transmits the operation of the locking member to the hook portion,
When the key is not inserted in the lock member, the actuating portion of the lock member cannot be displaced by a predetermined amount or more, and the actuating portion restricts displacement of the transmitting member by a predetermined amount or more, and the hook is hung by the transmitting member. Displacement of a predetermined amount or more to the hook portion unlocking side specific position side is regulated, and a predetermined amount between the hook portion and the movable engaging portion required to become the disengaged state in the locked state 4. The gaming machine according to any one of means 1 to 3, characterized in that the above relative displacement amount is not obtained.

According to the above means 5, the same operational effect as that of the above means 4 is obtained. For example, when the key is not inserted into the cylinder lock, the lock state of the cylinder lock is not released, and the transmission member engaged with the cam plate of the cylinder lock and thus the hook portion are maintained in a state in which they cannot be displaced by a predetermined amount or more. Etc. are mentioned as an example. In addition, in the configuration in which the displacement of the hook portion is restricted by the transmission member, for example, the transmission member and the hook portion are integrally formed, and when the displacement of the transmission member is restricted by this, the hook portion is not displaced, etc. Is also included.

Means 6. In the locked state, and in the state where there is no specific operation of the lock member by the key,
At least when the movable engaging portion is at the engagement portion locking side specific position, only the hook portion is displaced to the hook portion unlocking side specific position side, and the displacement limit of the hook portion in the locked state. Even when reaching the position, the engagement state of the hook portion and the movable engagement portion is maintained,
When at least the hook portion is at the hook portion locking side specific position, only the movable engaging portion is displaced to the engaging portion unlocking side specific position side, and the movable engaging portion in the locked state. The gaming machine according to any one of means 1 to 5, wherein the movable engagement portion and the hook portion are maintained in the engaged state even when the displacement limit position is reached.

According to the above means 6, in the locked state, displacing only one of the hook portion and the movable engaging portion in the unlocking direction without using the key does not release the engaged state of the two, and the door body Is not allowed to open. Therefore, if the hook or movable engaging portion is displaced in the unlocking direction by using a wire or the like and the engaging state of both is illegally released, the hooks engaging at one place Since a complicated operation such as hooking a wire rod or the like on the portion and the movable engaging portion or a complicated operation such as operating the hooked wire rod or the like in different directions, an unauthorized unlocking operation becomes difficult. As a result, the defense performance against unauthorized unlocking using a wire or the like is further improved. Depending on the configuration, the "displacement limit position" of the hook portion or the movable engaging portion may be the same position as the "hook portion unlocking side specific position" or the "engaging portion unlocking side specific position".

Means 7. When closing the door with respect to the support member without using the key,
While the movable engaging portion is in a state of being displaced to the engaging portion unlocking side specific position side, and the hook portion is displaced to the hook portion unlocking side specific position side, it is necessary to close the door body. The gaming machine according to any one of means 1 to 6, wherein a relative displacement amount of a predetermined amount or more between the hook portion and the movable engaging portion is obtained.

If the door body is closed to the support member without using a key, only one of the movable engaging portion and the hook portion is displaced to the unlocking side specific position side thereof. When trying to realize, there is a possibility that the engagement and arrangement of the movable engaging portion and the movable engaging portion restricting means, and the configuration of the locking mechanism such as the relationship between these and the hook portion may become complicated, By configuring the means 7 for displacing both the movable engaging portion and the hook portion, the locking mechanism can be simplified.

Means 8. Hook portion urging means for urging the hook portion to the hook portion locking side specific position side, and movable engaging portion urging means for urging the movable engaging portion to the engagement portion locking side specific position side. Equipped with
When closing the door body with respect to the support member, the hook portion and the movable engaging portion are brought into contact with each other, so that both of the hook portion and the movable engaging portion each have their own unlocking. 8. The gaming machine according to any one of means 1 to 7, wherein the gaming machine is displaced to a specific position side.

According to the above means 8, in addition to the same effect as the above means 7, it is possible to disperse and reduce the load applied to each of these when the hook portion and the movable engaging portion are in contact with each other. As a result, it is possible to reduce the occurrence of defects such as deformation and damage of the hooks and the like. If only one side is displaceable and such an effect is to be obtained, an urging means having a relatively weak urging force may be used, but in this case, the illegal act as described above is performed. Then, the hook portion or the movable engaging portion may be easily displaced to the unlocking side specific position side. In this respect, according to the present means, although the biasing means are used to some extent as the biasing means, the load is distributed to both, so that the impact force applied individually can be alleviated.

Means 9. 9. The gaming machine according to any one of means 1 to 8, characterized in that the movable engaging portion restricting means is configured not to interlock with the operation of the lock member in response to an operation by the key.

According to the above means 9, since the movable engaging portion restricting means does not interlock with the operation of the lock member, that is, does not interlock with the hook portion, the transmission member, or the like, the hook portion is temporarily made of wire or the like without using a key. Even if an illicit operation is performed on the transmission member or the transmission member, this stress is not transmitted to the movable engaging portion restricting means. In other words, the unlocking state cannot be set only by an unauthorized operation on the hook portion, the transmission member, or the like, so that the defense performance against the unauthorized unlocking is significantly improved. Note that the structure in which the movable engaging portion restricting means is not interlocked with the operation of the lock member can be realized by providing the movable engaging portion restricting means so as to be spaced apart without engaging with the hook portion, the transmission member, or the like.

As a more detailed example, "variable display of an identification information sequence (design sequence; specifically, a reel with a design, a rotating body such as a belt) including a plurality of identification information (designs) (specifically, a reel) The variable display means (specifically, a rotating body unit such as a reel unit) for stopping and displaying the identification information sequence after the rotation) is provided, and is caused by the operation of the starting operation means (specifically, the start lever). The variation of the identification information (symbol) is started, the variation of the identification information (symbol) is stopped due to the operation of the stop operation means (specifically, the stop button), and the identification is aligned on the effective line at the time of the suspension. A game value is provided on condition that the information is specific identification information, and a ball saucer (upper plate, etc.) is further provided to take in game balls from the ball saucer, and to the ball saucer. A gaming machine having a payout means for paying out a game ball, and the game start condition being satisfied by the game ball being taken in by the taking-in means".

Hereinafter, one embodiment in the case of being applied to a rotating type gaming machine which is a kind of gaming machine, specifically, a slot machine will be described in detail with reference to the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10 with the front door 12 closed, FIG. 3 is a perspective view of the slot machine 10 with the front door 12 open, and FIG. FIG. 8 is a front view of the slot machine 10 with a door 12 opened.

As shown in FIGS. 1 to 4, the slot machine 10 includes a housing 11 as a support member that forms an outer shell of the slot machine 10. The housing 11 is composed of a top plate 11a, a bottom plate 11b, a back plate 11c, a left side plate 11d, and a right side plate 11e, which are formed in a wooden plate shape, and adjacent plates 11a to 11e are fixed by a fixing means such as adhesion. As a result, it is formed in a box shape with the front surface opened as a whole. The plates 11a to 11e may be made of a synthetic resin panel or a metal panel instead of being made of a wooden panel, or may be made of a synthetic resin material or a metal material in an integral box shape. You may. The housing 11 configured as described above is attached to a so-called island facility by hitting a nail or the like when it is installed in the game hall.

A front door 12 as a door is provided on the front side of the housing 11. The front door 12 is attached so as to be openable and closable by a pair of upper and lower hinge mechanisms 25a and 25b provided on the left side plate 11d of the housing 11. As a result, the front door 12 is rotatably supported with respect to the housing 11 about an opening/closing axis extending in the vertical direction connecting the hinge mechanisms 25a and 25b, and the opening opens or closes the front open side of the housing 11. Is configured to be able to.

Further, the front door 12 cannot be opened due to the locking device 600 provided on the back side thereof and the support fitting 800 as the engaged means provided on the housing 11 side. Details of the locking mechanism including the locking device 600 and the support fitting 800 will be described later.

A game panel 30 is provided near the center of the front door 12 to notify the player of the game state. On the game panel 30, three vertically long display windows 31L, 31M, 31R are formed side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, 31R. The display windows 31L, 31M, 31R may be integrated into a single display window.

As shown in FIGS. 3 and 4, the inside of the housing 11 is divided into upper and lower parts by a partition plate 40, and a reel unit 41 constituting variable display means is attached to the upper part of the partition plate 40.

The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R, which are rotating bodies formed in a cylindrical shape (annular shape), respectively. Each of the reels 42L, 42M, 42R is rotatably supported such that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, 42R are arranged on the same axis extending in a substantially horizontal direction, and the reels 42L, 42M, 42R correspond to the display windows 31L, 31M, 31R in a one-to-one correspondence. .. Therefore, a part of the surface of each reel 42L, 42M, 42R is in a visible state through the corresponding display window 31L, 31M, 31R. A belt-shaped belt is wound around the outer peripheral surface of each reel 42L, 42M, 42R, and a large number of patterns as identification information are printed at equal intervals on the outer peripheral surface of this belt. Then, when the reels 42L, 42M, 42R rotate forward, the surfaces of the reels 42L, 42M, 42R are projected through the respective display windows 31L, 31M, 31R as if moving from top to bottom.

Each of the reels 42L, 42M, 42R is connected to a stepping motor 61L, 61M, 61R (see FIG. 6) as a driving unit, and each reel 42L is driven by driving the stepping motor 61L, 61M, 61R. , 42M, 42R can be driven individually, that is, independently of each other. Then, as the drive shafts of the stepping motors 61L, 61M, 61R rotate, the reels 42L, 42M, 42R rotate about the drive shafts so as to rotate.

Further, the reel unit 41 is provided with reel index sensors 55L, 55M, 55R (see FIG. 6). In the present embodiment, as each reel index sensor 55L, 55M, 55R, a transmissive photosensor in which a light emitting element and a light receiving element are held at a predetermined interval is adopted. Then, each reel index sensor 55L, 55M, 55R detects that a sensor cut van (not shown) passes between both elements every time the reels 42L, 42M, 42R make one revolution, and each time, a main control described later is performed. The detection signal is output to the device 131. Based on this detection signal, main controller 131 can confirm and correct the rotational position of each reel 42L, 42M, 42R almost every lap.

For example, in the present embodiment, the stepping motors 61L, 61M, 61R are set to rotate once by giving a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter). That is, each reel 42L, 42M, 42R is configured to rotate by an amount of rotation corresponding to the number of drive signals, such that each reel 42L, 42M, 42R changes in angle by 5° with a drive signal of 7 pulses. There is. Further, the drive signals control the rotational positions of the stepping motors 61L, 61M, 61R, that is, the rotational positions of the reels 42L, 42M, 42R.

On each belt of each of the reels 42L, 42M, and 42R described above, a plurality of symbols, specifically 21 symbols, are drawn in the long side direction (circling direction) thereof. Therefore, it takes 24 pulses (=504 pulses/21 symbols) to switch from one symbol to the next symbol at a predetermined position. Then, it is possible to recognize which symbol is visible from each display window 31L, 31M, 31R by the number of pulses from the time when the rotational position of each reel 42L, 42M, 42R is detected, or to select any symbol. It is possible to perform control such that the design is made visible from the display windows 31L, 31M, 31R.

Of the symbols attached to the reels 42L, 42M, 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, 31R is determined mainly by the vertical lengths of the display windows 31L, 31M, 31R. It is limited to a predetermined number. In this embodiment, each reel has three reels. Therefore, in a state where all the reels 42L, 42M, 42R are stopped, 3×3=9 symbols are visible to the player.

Here, the symbols attached to the reels 42L, 42M, 42R will be described. FIG. 5 shows the symbol arrays drawn on the belts wound around the left reel 42L, the middle reel 42M, and the right reel 42R, respectively. As shown in the figure, each reel 42L, 42M, 42R is provided with 21 symbols in a row. The numbers 1 to 21 are assigned to the reels 42L, 42M, and 42R, but these are given for convenience of description, and are not actually assigned to the reels 42L, 42M, and 42R. .. However, in the following description, the corresponding numbers will be used for description.

As the symbols, there are a "red 7" symbol (for example, 20th left belt) and a "white 7" symbol (for example, 19th left belt) as the first special symbol for shifting to the big bonus game. .. Further, there is a "BAR" symbol (for example, the 14th left belt) as a second special symbol for shifting to the regular bonus game. Also, there is a "replay" symbol (for example, eleventh left belt) as a third special symbol for shifting to a replay game. In addition, a "watermelon" design (for example, the left belt ninth), a "bell" design (for example, the left belt eighth), and a "cherry" design (for example, left There is a 4th belt). Then, as shown in FIG. 5, in the belts wound around the reels 42L, 42M, and 42R, the numbers of various symbols and the arrangement order are completely different.

The game panel 30 is provided with a combination line of three lines in parallel in the lateral direction and two lines in the diagonal direction so as to connect the display windows 31L, 31M, 31R, a total of five combination lines. Of course, the maximum number of combined lines may be 6 or more, or may be less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to each of these combination lines, effective line display portions 32, 33, 34 are provided on the left side of the display windows 31L, 31M, 31R viewed from the front. When the central horizontal line (central line) of the combination lines is activated, the first activated line display unit 32 is displayed and informed by lighting or the like. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second activated line display section 33 is informed by lighting or the like. When the pair of diagonal lines (downward rightward line and upward rightward line) of the combination lines are activated, the third effective line display unit 34 is informed by lighting or the like. Then, when the symbols are stopped in a predetermined combination on the activated combination line, that is, the activated line, the prize is won, and a predetermined medal payout process, a transition process to a specific game, and the like are executed.

Here, the payout number relating to each symbol in the case of winning will be described. Regarding small winning symbols, if the "watermelon" symbol is aligned with the left, middle and right on the activated line, 15 medals are paid out, and if the "bell" symbol is aligned with the left, medium and right on the activated line. Pays out eight medals, and pays out two medals when the "cherry" symbol on the left reel 42L stops on the activated line. That is, the "cherry" symbols on the middle reel 42M and the right reel 42R are unrelated to the medal payout. In addition, since only the "cherry" symbol is paid out regardless of the combination with other symbols, the "reel" symbol is placed at a position (specifically, the upper row or the lower row) where the plural effective lines of the left reel 42L overlap. When the "cherry" symbol is stopped, medals are paid out only by multiplying the number of overlapping effective lines, and as a result, four medals are paid out in the present embodiment.

Also, for other symbols, if the "Red 7" symbol or the "White 7" symbol, which is the combination of the first special symbol (big bonus symbol), is aligned with the left, middle, and right on the same line in the same symbol. 15 coins are paid out, and 15 coins are paid out even when the "BAR" symbol, which is a combination of the second special symbol (regular bonus symbol), is aligned with the left, middle, and right on the activated line. In the present embodiment, for example, there may be a case where the “red 7” symbol and the “cherry” symbol are established at the same time, but in such a case, the medal payout is 15 coins. This is because the maximum number of coins to be paid out once is set to 15.

Furthermore, when the "replay" symbol, which is the combination of the third special symbols, is aligned with the left, middle, and right on the activated line, the medal payout is not performed. In other cases, that is, when the "cherry" symbol of the left reel 42L does not stop on the activated line and the same symbols as the left, middle, and right are not aligned on the activated line, no medal is paid out.

Here, the bonus game in the present embodiment will be described. The regular bonus (hereinafter referred to as “RB”) game is composed of 12 JAC games. The JAC game is a game in which only one bet is allowed, and the probability that the JAC symbols (here, the replay symbols are substituted) are aligned on the activated line, that is, the establishment of the JAC symbols is very high. When the JAC symbol is established in the JAC game, the maximum number (15 here) of medals are paid out. When the JAC symbol is established eight times, the RB game ends even before the JAC game reaches 12 times. On the other hand, the big bonus (hereinafter referred to as “BB”) game is composed of 30 small winning games and 3 JAC ins. The small role game is a game in which a small role is highly likely to be won (the “bell” symbols and the like are lined up on the activated line), and the JAC in means entering 12 JAC games. When the JAC symbols are lined up on the activated line, the JAC in is established. The JAC game is similar to the RB game. Also, when the JAC game with the third JAC in ends, the BB game ends even before the small win game reaches 30 times, and when the 30 small win games end, before the JAC in reaches 3 times. Even if there is, the BB game ends. The form of the bonus game is not limited to the form described above, and may be different forms.

By the way, on the lower left side of the game panel 30, there is provided a start lever 71 which is operated to start the rotation of the reels 42L, 42M and 42R all at once (not necessarily at the same time). The start lever 71 constitutes a starting operation means that is operated to start rotation of the reels 42L, 42M, 42R, that is, to start variable display. The start lever 71 is a lever that the player pushes with his/her hand when starting the game, and automatically returns to the original position after the hand is released. When the start lever 71 is operated while a medal is inserted, the reels 42L, 42M, 42R start rotating all at once.

On the right side of the start lever 71, button-shaped stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. The stop switches 72, 73, 74 are arranged substantially directly below the display windows 31L, 31M, 31R corresponding to the reels 42L, 42M, 42R to be stopped. The stop switches 72, 73, 74 constitute stop operation means operated to stop the variable display based on the rotation of the reels 42L, 42M, 42R. Each of the stop switches 72, 73, and 74 is in a state in which it can be stopped after a predetermined time has elapsed since the left reel 42L started to rotate, and in this state, a lamp (not shown) is lit and displayed to stop. It is notified that the operation is possible, and is turned off when the rotation is stopped.

On the lower right side of the display windows 31L, 31M, 31R, a medal insertion slot 75 for inserting medals is provided. The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by a selector 84 provided on the back surface of the front door 12 as passage switching means. That is, the selector 84 is provided with a medal passage switching solenoid 83 (see FIG. 6), and when the medal passage switching solenoid 83 is not excited, the medal passage switching solenoid 83 is set to the discharge passage 82 side, and when excited, the medal passage switching solenoid 83 is switched to the storage passage 81 side. Has become. The medals guided to the storage passage 81 are guided to the hopper device 91 housed inside the housing 11. On the other hand, the medals guided to the discharging passage 82 are guided to the medal receiving tray 18 from the medal discharging port 17 provided at the lower front portion of the front door 12 and returned to the player.

The hopper device 91 as a payout means for giving the medals to the player is composed of a storage tank 92 for storing the medals and a payout device 93 for paying out the medals to the player. The payout device 93 rotates a medal payout rotating plate (not shown) to eject the medals into an opening 94 provided in the center right portion of the ejection passage 82, and to the medal tray 18 via the ejection passage 82. Are to be paid out. Further, on the right side of the hopper device 91, a spare tank 95 is provided for avoiding that a predetermined amount or more of medals are stored in the storage tank 92. Inside the storage tank 92 of the hopper device 91, a guide plate 96 for discharging medals from the storage tank 92 to the spare tank 95 is provided. Therefore, when the medals are stored at a height higher than the height at which the guide plate 96 is provided, the medals are stored in the spare tank 95.

A button-shaped return switch 76 is provided below the medal insertion slot 75. The return switch 76 is a switch that is pressed when the medals inserted into the medal insertion slot 75 are jammed in the selector 84, and when this switch is pressed, the selector 84 is mechanically interlocked and operates. The medals clogged in 84 are returned from the medal discharge port 17.

On the lower left side of the display windows 31L, 31M, 31R, a button-shaped first credit insertion switch 77 for inserting three credited virtual medals at a time is provided. Further, on the left side of the first credit input switch 77, a second credit input switch 78 is provided as a button-shaped switch smaller than the switch 77. The second credit insertion switch 78 is for inserting one credited virtual medal at a time.

The first credit insertion switch 77 has a built-in lamp as a light emitting member (not shown) in order to promote that the maximum number of medals (three coins) that can be inserted per game is not reached. The lamp is turned on when the switch operation of the first credit insertion switch 77 is valid and prompts the operation of the switch 77, but when there is no credited virtual medal or three medals have already been inserted. It is turned off under the situation. Here, instead of the above lighting, it may be blinked to make it easier for the player to recognize the medal insertion.

On the left side of the start lever 71, a button-shaped changeover switch 80 is provided. The changeover switch 80 is in a toggle type in which it is turned on when pressed once, turned off when pressed again, and turned on and off each time the pressing operation is performed thereafter. The changeover switch 80 is operated in order to change the handling mode of the inserted medals inserted into the medal insertion slot 75 in an amount larger than the required amount and the acquired medals returned to the player as a result of a predetermined game.

When the changeover switch 80 is in the ON state, a surplus inserted medal until reaching a predetermined maximum value (for example, 50 medals) and an obtained medal at the time of winning are set to be stored and stored as a credit medal. It becomes. When the changeover switch 80 is in the off state, the "direct mode" is set in which the surplus inserted medals and the medals acquired at the time of winning are paid out as the actual medals. If there are credit medals when the credit mode is switched to the direct mode, the corresponding credit medals are paid out as actual medals. Thus, the player can execute the game in a format according to his/her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for changing over the handling type. Further, if attention is paid to the function of paying out the credited virtual medal as an actual medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored and stored game value. It should be noted that, in addition to the configuration in which the "credit mode" and the "direct mode" are switched by operating the changeover switch 80, the virtual medals stored and stored are paid out when the changeover switch 80 is operated by always keeping the "credit mode". You may make it function as a settlement switch only.

Below the display windows 31L, 31M, 31R of the game panel 30, a remaining number display section 35 for displaying the number of medals activated and stored in the credit mode, and a special game state such as a big bonus or a regular bonus. Further, for example, a game number display section 36 for displaying the number of remaining games and the like, and an acquired number display section 37 for displaying the number of acquired medals are respectively provided. Although these display portions 35 to 37 are composed of 7-segment displays, they can be replaced by liquid crystal displays or the like.

Here, a procedure for betting a medal will be described. In both the direct mode and the credit mode, a bet is made when a medal is inserted from the medal insertion slot 75 at the start of the game.

That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display portion 32 lights up, and the corresponding center line becomes the effective line, and the second medal becomes the medal insertion slot. When it is thrown into 75, the second effective line display section 33 is further turned on, and a total of three combined lines including the upper line and the lower line corresponding thereto become effective lines, and the third medal becomes the medal. When inserted into the insertion port 75, the third effective line display portion 34 is further turned on, and all five combined lines including a pair of diagonal lines corresponding thereto become all effective lines.

When four or more medals are inserted into the medal insertion slot 75, the surplus medals exceeding three medals are switched to the discharge passage 82 by the selector 84 if the mode at that time is the direct mode. It is returned from the outlet 17 to the medal tray 18. On the other hand, in the credit mode, the number of savings is displayed in the remaining number display section 35 while the savings are made inside the slot machine. An upper limit is set for this stored number (for example, 50), and when more medals are inserted, they are returned from the medal outlet 17 to the medal tray 18.

Further, when the game is played in the credit mode and the remaining number of coins is displayed on the remaining number display section 35, the virtual medal is displayed even when one of the first and second credit insertion switches 77 and 78 is pressed. Bet has been thrown and it becomes a bet.

For example, when the second credit insertion switch 78 is pressed, the number displayed on the remaining number display unit 35 is decremented by 1 as one virtual medal has been inserted, and the first effective line display unit is displayed. 32 is turned on and the central line becomes the effective line. When the first credit insertion switch 77 is pressed, the number displayed on the remaining number display section 35 is decremented by 3 as the three virtual medals have been inserted, and all the activated line display sections are displayed. 32 to 34 are turned on, and a total of 5 combined lines are effective lines.

In addition, when the virtual medals to be inserted when any of the first and second credit insertion switches 77 and 78 are pressed, for example, when the display of the remaining number display unit 35 is 2, the first credit is displayed. When the insertion switch 77 is pressed, all the numerical values in the remaining number display section 35 are decremented to 0, and the bet is made for the virtual medals that can be inserted.

On the upper part of the front door 12, an upper lamp 13 that lights up or blinks as the game progresses, and a pair of left and right that emits various sound effects as the game progresses and informs the player of the game state. The speaker 14A and the auxiliary display unit 15 for giving various information to the player are provided. In the present embodiment, the auxiliary display unit 15 is composed of a liquid crystal display for the purpose of diversifying the display contents and increasing the display effect, but even if another display such as a dot matrix display is used. Good. The auxiliary display unit 15 is for executing various display effects as the game progresses, and since it is possible to think that the game with each reel 42L, 42M, 42R is the main display unit, in the present embodiment. It is called the auxiliary display unit 15. An upper lamp 13, a speaker 14A, and a display control device 111 for driving the auxiliary display unit 15 are provided on the back surface of the auxiliary display unit 15. The positions and the numbers of the upper lamp 13 and the speaker 14A are not limited to those described above.

Above the medal tray 18, a lower plate 16 on which a model name and characters relating to a game are displayed is attached. Further, on the left side of the medal tray 18, a reversible ashtray 19 is provided below the front side. Further, behind the medal tray 18, a pair of left and right speakers 14B similar to the speaker 14A is provided.

A power supply box 121 is provided on the left side of the hopper device 91 inside the housing 11. The power supply box 121 includes a power switch 122, a setting key insertion hole 124, and the like. The power switch 122 is a start switch for supplying power to each unit including the main controller 131. The setting key insertion hole 124 is used by a hole manager or the like to adjust the payout of medals. That is, the hall manager or the like can change the setting state (winning probability setting process) of the slot machine 10 from “setting 1” to “setting 6” by inserting and operating the setting key into the setting key insertion hole 124. It has become.

Above the reel unit 41, a main control device 131 as a main control means is attached to the back plate 11c of the housing 11. The main controller 131 is a CPU that controls the main control, a ROM that stores a game program, a RAM that temporarily stores necessary data according to the progress of the game, a port that communicates with various devices, time counting and synchronization. A main board including a clock circuit and the like used in the case of aiming is provided, and the main board is housed in a board box made of a transparent resin material or the like as an enclosing means. The substrate box includes a box base having a substantially rectangular parallelepiped shape and a box cover that covers an opening of the box base. The box base and the box cover are connected in a non-openable manner by a sealing unit as a sealing means, whereby the substrate box is sealed.

Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

The main controller 131 is equipped with a microcomputer centered on a CPU 151 which is an arithmetic processing unit. In addition to the power supply device 161 provided inside the power supply box 121, a clock circuit 154 that outputs a rectangular wave of a predetermined frequency, an input/output port 155, and the like are connected to the CPU 151 via an internal bus. The main controller 131 functions as a main board built in the slot machine 10.

On the input side of the main controller 131, a start detection sensor 71a for detecting the operation of the start lever 71, stop detection sensors 72a, 73a, 74a for individually detecting the operation of the stop switches 72, 73, 74, and a medal insertion slot. Insertion medal detection sensor 75a for detecting medals inserted from 75, credit insertion detection sensors 77a, 78a for individually detecting operation of each credit insertion switch 77, 78, switching detection sensor 80a for detecting operation of changeover switch 80, Reel index sensors 55L, 55M, 55R that individually detect the rotational positions of the reels 42L, 42M, 42R, a payout detection sensor 91a that detects medals paid out from the hopper device 91, and a reset detection sensor 640 that detects a reset operation described below. The setting key detection sensor 124a for detecting that the setting key is inserted into the setting key insertion hole 124, the opening detection switch 820 for detecting the opening of the front door 12, and the opening operation of the front door 12 by the key K described later are performed. Various sensors such as an opening operation detection sensor 630 for detecting the presence of the presence are connected, and signals from these various sensors are output to the CPU 151 via the input/output port 155.

The inserted medal detection sensor 75a is actually composed of a plurality of sensors. That is, the storage passage 81 extending from the medal insertion slot 75 to the hopper device 91 is configured such that medals can pass in a single row at the upstream portion thereof. Then, the first sensor is provided in the upstream portion of the storage passage 81, and the second sensor and the third sensor are close to the downstream side apart from the medal width by at least the width of the medal (a state in which the same medal is simultaneously detected at least temporarily). Are provided in close proximity to each other), and the inserted medal detection sensor 75a is configured by these first to third sensors. The main control device 131 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, considers that the medal is clogged or fraudulently, and makes an error. When an error occurs, error notification is given and the operation by the player until the error is canceled is invalidated. The main controller 131 also monitors the order in which the second sensor and the third sensor are turned on and off, and both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. It is determined that the medals have been normally taken in only when the sequence is such that only the third sensor is turned on and both the second and third sensors are turned off, and when the time for switching to each on/off switching is within a predetermined time. However, in other cases, it is an error. This is done in order to prevent fraud in which the medals are jammed in the storage passage 81 and the medals are reciprocally moved in the vicinity of the inserted medal detection sensor 75a and are mistakenly recognized as the inserted medals.

A power failure monitoring circuit 161b provided in the power supply device 161 is connected to the input side of the main control device 131 via the input/output port 155. The power supply device 161 is equipped with a power supply unit 161a that supplies drive power to each electronic device of the slot machine 10 including the main control device 131, the above-described power failure monitoring circuit 161b, and the like.

The power failure monitoring circuit 161b is for monitoring the power cut-off state and generating a power failure signal when the power switch 122 shuts down the power as well as at the time of power failure. In this example, the stabilized drive voltage of DC 12 V is monitored, and when the drive voltage drops to less than 10 V, for example, it is determined that the voltage is cut off, and a power failure signal is output. The power failure signal is supplied to each of the CPU 151 and the input/output port 155, and the CPU 151 recognizes the power failure signal to execute a predetermined power failure process.

When the power is cut off due to a power failure or the like, the backup area has a stack pointer, a value of each register, I/O, etc. when the power is cut off (including the cutoff of the power by operating the power switch 122). The area of the slot machine 10 is in the state before the power is shut off, based on the information in the backup area when the power failure is resolved (including powering on by operating the power switch 122. The same applies hereinafter). It is possible to return to the state. Writing to the backup area is executed when the power is cut off by the power failure process, and each value written in the backup area is restored in the main process when the power is turned on. The NMI terminal (non-maskable interrupt terminal) of the CPU 151 is configured to receive a power failure signal from the power failure monitoring circuit 161b when the power is shut off due to a power failure or the like. Interrupt processing is executed immediately.

The power supply unit 161a of the power supply device 161 holds the output of the stabilized voltage (5 volts) used as the drive voltage of the control system for a sufficient time to execute the NMI interrupt processing and the power failure processing described above.

Next, the lock mechanism of the front door 12 will be described. The locking mechanism of the front door 12 is configured by the locking device 600 attached to the front door 12 and the support fitting 800 attached to the housing 11 as described above.

The locking device 600 is attached along the rear side of the right side of the front door 12, that is, the side of the front door 12 opposite to the rotating shaft side. On the other hand, the support fitting 800 is attached to the inside of the right side plate 11e of the housing 11 in correspondence with the locking device 600. Then, when the front door 12 is closed with respect to the housing 11, the locking device 600 and the support fitting 800 are engaged with each other to be in the locked state, so that the opening of the front door 12 is restricted. The main members constituting the locking device 600 and the support fitting 800 are formed by pressing a metal flat plate.

Further, in the closed state of the front door 12, only the cylinder lock 700 (see FIG. 1, etc.) described later of the locking device 600 is exposed to the front side of the front door 12. Then, by inserting the key K into the key hole 702 of the cylinder lock 700 and rotating the key K in a predetermined direction (clockwise direction in the present embodiment), the locking device 600 and the support fitting 800 are unlocked, and the front surface. The door 12 is allowed to be opened.

First, the locking device 600 will be described in detail with reference to FIGS. 7 to 14. FIG. 7 is a perspective view of the locking device 600 and the support fitting 800 as viewed from the rear left side, and FIG. 8 is a perspective view of the lock device 600 and the support fitting 800 as viewed from the front left side. However, in FIGS. 7 and 8, for convenience, the casing 11 and the front door 12 related to the locking device 600 and the support fitting 800 are also schematically illustrated. 9 is an exploded perspective view of the locking device 600 and the support fitting 800 as viewed from the rear left side, and FIG. 10 is an exploded perspective view of the locking device 600 and the support fitting 800 as viewed from the front left side. 11 is a rear view of the locking device 600, FIG. 12 is a right side view, FIG. 13 is a front view, and FIG. 14 is a left side view.

The vertically long base frame 601 forming the outer shell of the locking device 600 includes a mounting plate 602 as a mounting portion fixed to the back surface of the front door 12, and an end of the mounting plate 602 on the inner side (left side) of the front door 12. A support plate 603 as a support portion protruding rearward from the edge and a flange portion 604 protruding rearward from the edge of the mounting plate 602 on the outer side (right side) of the front door 12 are provided, and these are integrated. The cross section is generally U-shaped.

The mounting plate 602 has a wide portion 602a that is wider in the left-right direction than a predetermined position in a predetermined vertical section corresponding to the position where the cylinder lock 700 is arranged. In the support plate 603, a vertical section corresponding to the wide section 602a is formed. The bulging portion 603a bulges inward of the front door 12. This secures the installation space at the position where the cylinder lock 700 is arranged while making the entire width of the locking device 600 as narrow as possible in order to secure a wider installation space for the area of the game panel 30 and various devices. This is because

Inside the support plate 603 (outer side of the front door 12), a first sliding rod 610 and a pair of upper and lower hook members 611 and 612, which are main components of the locking mechanism, are arranged. The hook members 611 and 612 correspond to the hook portion in this embodiment, and the first sliding rod 610 corresponds to the transmission member.

The first sliding rod 610 has an elongated shape and is arranged along the support plate 603 so as to be slidable in the vertical direction. The first sliding rod 610 is provided with a bulging portion 610a bulging inward of the front door 12 in a predetermined vertical section corresponding to the bulging portion 603a of the support plate 603. However, the formation section of the bulging portion 610a of the first sliding rod 610 is set shorter than the formation section of the bulging portion 603a of the support plate 603, and does not hinder the sliding of the first sliding rod 610. It is like this.

The hook members 611 and 612 are rotatably supported by the support plate 603 by shaft pins 613 and 614. Further, the first sliding rod 610 is attached to the support plate 603 so as to overlap with the front ends of the hook members 611 and 612 and the vicinity thereof (the end on the mounting plate 602 side and its vicinity) from the outside of the front door 12. It is arranged in the opposite direction. Then, in the overlapping portion, the first sliding rod 610 and the hook members 611 and 612 are engaged with each other via the shaft pins 615 and 616. As a result, the hook members 611 and 612 are rotationally displaced in association with the vertical sliding movement of the first sliding rod 610.

The hook members 611 and 612 have locking recesses 611a and 612a formed on their upper sides, and their rear portions project rearward from the support plate 603. As a result, the hook members 611 and 612 have hook-like portions protruding rearward from the support plate 603, and the protruding portions function as locking portions (locking claws).

Further, the rear end side of the locking recesses 611a, 612a in the hook members 611, 612, that is, the heads 611b, 612b of the hook members 611, 612 are inclined parts 611c, 612c whose upper side parts are inclined downward toward the rear. ing.

It should be noted that the mounting plate 602 is provided with restricting projections 602b that restrict the movement of the first sliding rod 610 to the outside of the front door 12 at three positions in the vertical direction. Further, the support plate 603 is provided with a support protrusion 603b that protrudes toward the outside of the front door 12 at a position above the bulging portion 603a. The regulation projection 602b and the support projection 603b have a function of enhancing the stability of the mounting state of the first sliding rod 610 and a function of a guide portion of enhancing the stability of the sliding operation of the first sliding rod 610. There is. Therefore, the first sliding rod 610 is restricted from moving in the left-right direction (left-right direction in FIG. 11) by the restriction projection 602b of the mounting plate 602 and the support projection 603b of the support plate 603, and is also connected to the hook members 611 and 612. With the engagement of, the movement in the front-rear direction (the left-right direction in FIG. 12) is restricted, and the slide can be performed in the vertical direction.

Further, near the lower end portion of the first sliding rod 610, a protrusion piece 617 that protrudes toward the inner side of the front door 12 is provided at a position slightly higher than the engagement position with the lower hook member 612. There is. Correspondingly, a notch recess 618 is formed at the rear edge of the support plate 603, and the protruding piece 617 projects inward from the support plate 603 to the inside of the front door 12 via the notch recess 618. ing.

Further, the support plate 603 is provided with a mounting base portion 619 projecting inward of the front door 12 at a position above the cutout recess 618. An opening operation detection sensor 630 is attached to the lower surface side of the attachment base portion 619. In this embodiment, as the opening operation detection sensor 630, a transmissive photosensor in which a light emitting element and a light receiving element are held at a predetermined interval is used. Then, when there is a sliding displacement of the first sliding rod 610 upward, that is, when there is an opening operation of the front door 12 by the key K as described later, the projecting piece 617 causes the opening operation detection sensor 630. , The opening operation detection sensor 630 detects this, and outputs a detection signal to the main controller 131 described later. Based on this detection signal, main controller 131 can recognize that key K has opened front door 12.

Further, a second sliding rod 620 is arranged on the supporting plate 603 so as to be sandwiched between the supporting plate 603 and the first sliding rod 610. However, the vertical length of the second sliding rod 620 is set to be relatively short, and the second sliding rod 620 extends from near the upper end of the bulging portion 610a of the first sliding rod 610 to a position slightly above the opening operation detection sensor 630. It is provided corresponding to the section. Therefore, the second sliding rod 620 is arranged along the upper piece 620a arranged along the bulging portion 610a of the first sliding rod 610 and the general portion of the first sliding rod 610. The lower piece portion 620b and the lower piece portion 620b are formed with a step.

The lower piece 620b of the second sliding rod 620 is provided with a first protrusion 621 protruding from the lower end toward the inside of the front door 12, and from the rear edge near the lower end toward the inside of the front door 12. The 2nd protrusion piece 622 which protruded toward the side is provided. Correspondingly, insertion holes 623 and 624 are formed in the support plate 603, and both projection pieces 621 and 622 are inward from the support plate 603 through the insertion holes 623 and 624, respectively. It is protruding. The first projection piece 621 functions as a manual operation portion for sliding the second sliding rod 620 downward and performing a resetting operation as described later. On the other hand, the second protrusion piece 622 functions as a detected portion detected by the reset detection sensor 640 described later.

Further, the support plate 603 is provided with a mounting base portion 625 that protrudes inward from the front door 12 at a position above both insertion holes 623 and 624. A reset detection sensor 640 is attached to the lower surface side of the attachment base 625. In this embodiment, as the reset detection sensor 640, a transmissive photosensor similar to the opening operation detection sensor 630 is adopted. In a normal state, that is, when the second sliding rod 620 is at the reference position, the second protrusion 622 is inserted between both elements of the reset detection sensor 640. Then, when there is a sliding displacement of the second sliding rod 620 to the lower side, that is, when there is a resetting operation via the key K or the first protruding piece 621 as described later, the second protruding piece 622. Goes out between both elements of the reset detection sensor 640, the reset detection sensor 640 detects this, and outputs a detection signal to the main control device 131 described later. Main controller 131 can recognize that a reset operation has been performed based on this detection signal.

Now, the first sliding rod 610 is urged downward by a coil spring C1 as a hook urging means. More specifically, the coil spring C1 has one end hooked on a hook portion 641 provided at a substantially central portion in the vertical direction of the first sliding rod 610, and the other end has a hook provided on the rear surface side of the mounting plate 602. It is hung on the portion 642.

Further, the second sliding rod 620 is biased upward by the coil spring C2. More specifically, the first sliding rod 610 has a hook portion 643 formed at a position slightly lower than the bulging portion 610a, and a notch recess 644 formed at a front edge portion located at a position lower than the hook portion 643. .. A hook portion 645 is formed near the lower end of the second sliding rod 620. Then, one end of the coil spring C2 is hooked on the hook portion 643 of the first sliding rod 610, and the other end of the coil spring C2 protrudes to the outside of the front door 12 of the first sliding rod 610 through the cutout recess 644. It is hooked on the hook portion 645 of the second sliding rod 620.

Then, when the cylinder lock 700 is operated, the first sliding rod 610 slides upward or the second sliding rod 620 slides downward against the tensile force of the coil springs C1 and C2. To do.

Normally, the first sliding rod 610 is held at the reference position as shown in FIG. 7 and the like by the tensile force of the coil spring C1. In this state, the hook members 611 and 612 engaged with the first sliding rod 610 have their front end portions pulled downward and come into contact with the lower regulation protrusions 647 and 648 provided on the support plate 603, so that It is maintained in a horizontal state (see FIG. 23). In addition, since the movement of the hook members 611 and 612 is restricted by the lower restriction protrusions 647 and 648, the downward movement of the first sliding rod 610 is also restricted.

When the first sliding rod 610 slides upward, the hook members 611 and 612 are rotationally displaced in conjunction with this. However, the hook members 611 and 612 come into contact with the upper restriction protrusions 649 and 650 provided on the support plate 603, so that further rotation is restricted. In this state, the hook members 611 and 612 are inclined such that the front end side thereof is upward and the rear end side thereof is downward (see FIG. 24).

Therefore, in the rotational displacement range of the hook members 611 and 612, the position where the hook members 611 and 612 contact the lower regulation protrusions 647 and 648 corresponds to the hook portion locking side specific position (reference position) in the present embodiment. .. On the other hand, the position where the hook members 611 and 612 contact the upper restriction protrusions 649 and 650 corresponds to the hook portion unlocking side specific position.

On the other hand, the second sliding rod 620 is normally held at the reference position as shown in FIG. 7 and the like by the tensile force of the coil spring C2. In this state, the second sliding rod 620 is in a state in which the upward movement is suppressed by the protrusion pieces 621 and 622 being biased to the upper edge portions of the insertion holes 623 and 624. Further, in this state, as described above, the second protrusion piece 622 is in a state of being inserted between both elements of the reset detection sensor 640. When there is a downward sliding displacement of the second sliding rod 620, the second projecting piece 622 is in a state of being pulled out between both elements of the reset detection sensor 640.

A cylinder lock 700 as a lock member is attached to the wide portion 602a of the mounting plate 602. As shown in FIG. 19, a cylinder lock 700 includes a cylinder body 701 having a substantially tubular shape, a lock shaft 703 provided inside the cylinder body 701 and having a key hole 702 therein, and an outer periphery of the cylinder body 701. The external cylinder 704 is provided.

In the cylinder lock 700, the flange portion 705 is fixed to the rear surface side of the mounting plate 602 with a screw 699 while the cylinder body 701 is inserted into the mounting hole 602b of the mounting plate 602.

The cylinder body 701 is formed with a total of 16 through holes 706, each of which is in the upper and lower sides and which communicates the inside and the outside of the cylinder body 701. Corresponding to this, the lock shaft 703 is also formed with 16 through holes 708 communicating with the through holes 706. The keyhole 702 side of the through hole 708 is formed to have a smaller diameter than other portions so that a housing member such as a pin 714 described later does not drop into the keyhole 702.

A spring 709 is housed in each through hole 706. One end of the spring 709 is in contact with the outer cylinder 704, and the other end is connected to a pedestal 711. A plurality of spacers 712 and 713 and a pin 714 are accommodated in each through hole 708 so as to be supported by the pedestal 711. The pins 714, spacers 712, 713, and pedestal 711 can move up and down in the through holes 706 and 708 by expansion and contraction of the spring 709. Of these, the pin 714 can be retracted into the keyhole 702 through the small diameter portion of the through hole 708 on the keyhole 702 side.

With the above configuration, when the key K is inserted into the keyhole 702, the pins 714 and the like move up and down along the uneven shapes on the upper and lower sides of the key K. Then, when the insertion of the key K is completed, as shown in FIG. 20, the pins 714 enter the groove of the key K respectively, and the base end surface of the pin 714 or one end surface of the spacer 712 or 713 is inserted. And the outer peripheral surface of the lock shaft 703 are flush with each other. As a result, when the insertion of the key K is completed, the lock shaft 703 can be rotated along with the rotation operation of the key K. That is, this cylinder lock 700 has an internal structure in which the lock shaft 703 cannot be rotated unless the key K is inserted into at least the key hole 702.

Further, a cam plate 720 is fixed to the rear end portion of the lock shaft 703 for transmitting the rotational movement of the key K inserted in the key hole 702 to the first sliding rod 610 or the second sliding rod 620.

The cam plate 720 includes a pair of upper and lower engaging claws 720a and a lower engaging claw 720b. These engaging claws 720a and 720b are formed at predetermined intervals in the rotating direction of the cam plate 720.

Accordingly, the bulging portion 610a of the first sliding rod 610 is formed with a pair of upper and lower upper engaging holes 725 and lower engaging holes 726 through which engaging claws 720a and 720b can be inserted and withdrawn. Similarly, a pair of upper and lower engaging holes 727 and a lower engaging hole 728 through which engaging claws 720a and 720b can be inserted and removed are formed in the upper piece portion 620a of the second sliding rod 620. Further, the bulging portion 603a of the support plate 603 is formed with a through hole 730 so as not to interfere with the operation of the engaging claws 720a and 720b.

The engaging holes 725 and 726 of the first sliding rod 610 and the engaging holes 727 and 728 of the second sliding rod 620 are the upper portions of the bulging portion 610a of the first sliding rod 610 and the second sliding rod 620. In the overlapping state of the portions 620a, at least the upper engaging holes 725 and 727 and the lower engaging holes 726 and 728 are in a communicating state (see FIG. 21).

On the side of the first sliding rod 610, the upper engagement hole 725, which is located above among the engagement holes 725 and 726, has a longer vertical forming section than the lower engagement hole 726. Has been done. On the other hand, on the side of the second sliding rod 620, the lower engaging hole 728, which is located below among the engaging holes 727 and 728, has a longer vertical forming section than the upper engaging hole 727. Is set to. This is to prevent the upper engaging claw 720a or the lower engaging claw 720b from contacting the other of the first sliding rod 610 and the second sliding rod 620 when the cam plate 720 slides, as described later. This is to prevent the other from sliding.

With the above configuration, when the key K is not inserted into the key hole 702 of the cylinder lock 700 and the lock shaft 703 and the cam plate 720 are at the reference position, as shown in FIG. The tip of the upper engaging claw 720a is not inserted into the upper engaging holes 725 and 727 of the first sliding rod 610 and the second sliding rod 620, and the tip of the lower engaging claw 720b is the first sliding rod. The moving rod 610 and the lower engaging holes 726 and 728 of the second sliding rod 620 are not inserted.

Further, the first sliding rod 610 is provided with a stopper portion 731 protruding from the lower edge portion of the lower engagement hole 726 toward the outside of the front door 12. When the first sliding rod 610 is moved in the unlocking direction (upward) by a force other than the cam plate 720 in the closed state of the front door 12, the stopper portion 731 is, for example, the first sliding rod without using the key K. When the wire rod or the like is illegally hooked on the moving rod 610 and an external force in the unlocking direction is applied, the unlocking of the first sliding rod 610 is achieved by contacting the lower engaging claw 720b of the cam plate 720. It prevents sliding in the direction and prevents unauthorized unlocking.

As described above, the cylinder lock 700 of this embodiment is in a state (lock state) in which the lock shaft 703 and the cam plate 720 cannot be rotated when the key K is not inserted in the key hole 702. Therefore, even when the stopper portion 731 is caught by the lower engaging claw 720b of the cam plate 720, the cam plate 720 does not rotate, and the first sliding rod 610 is slid upward, and thus the hook members 611 and 612. The displacement in the unlocking direction is substantially restricted except for the play width. Therefore, the cylinder lock 700, the stopper portion 731, and the like constitute the hook portion restricting means in this embodiment.

Further, the support plate 603 is provided with a lock member 660 as a movable engaging portion restricting means (restricting member) above the upper hook member 611. When the front door 12 is closed, the lock member 660 regulates the sliding displacement of the receiving metal fitting 803 on the supporting metal fitting 800 side due to an illegal unlocking operation, and maintains the receiving metal fitting 803 at the reference position, whereby the front door This is to prevent unauthorized unlocking of item 12.

The lock member 660 includes a vertically elongated and substantially flat plate-shaped main body piece 660a. A shaft hole 660b is formed in the upper portion of the main body piece 660a, and a guide hole 660c is formed in the lower portion. The guide hole 660c is formed in a substantially arc shape with the shaft hole 660b as the center. Then, the shaft pins 663 and 664 respectively inserted into the shaft hole 660b and the guide hole 660c from the outside of the front door 12 are fixed to the support plate 603. Accordingly, the lock member 660 is pivotally supported so as to be pivotally displaceable around the shaft hole 660b (the shaft pin 663).

A hook portion 660d that protrudes outward of the front door 12 is provided at the upper rear edge of the main body piece 660a. Then, one end of the coil spring C3 as the regulating member urging means is hooked on the hook portion 660d, and the other end is hooked on the hook portion 665 provided on the mounting plate 602. Normally, the lock member 660 is in a state in which the lower portion is biased rearward by pulling the upper portion forward by the tensile force of the coil spring C3. In this state, the lock member 660 is in a state in which the front edge portion of the guide hole 660c is in contact with the shaft pin 664 and takes the reference posture as shown in FIG. This position (state) corresponds to the first position (first state) of the lock member 660 in this embodiment. The size (formation range) of the guide hole 660c is such that at least the lock member 660 is rotated by being pushed by the receiving metal fitting 803 as described later from the position where the lock member 660 takes the reference posture, and the head 611b of the hook member 611. Has a size such that its upper end can be displaced to a position beyond the engaging portion 803f of the receiving metal fitting 803.

A stopper portion 660e protruding outward of the front door 12 is provided at the lower end of the body piece 660a. As will be described later, the stopper portion 660e has a function of restricting the sliding displacement of the receiving metal fitting 803 on the supporting metal fitting 800 side.

Further, a rib 667 protruding toward the outside of the front door 12 is provided at the rear edge of the support plate 603 at a position corresponding to the lock member 660. The rib 667 has a function as a detected part that comes into contact with an opening detection switch 820 described later, and also prevents a wire or the like from entering the inside of the base frame 601 and prevents an unauthorized unlocking operation of the lock member 660 and the like. And so on.

Further, a cover member 670 made of synthetic resin is fixed to the lower end portion of the support plate 603 with screws 698. The lower part of the rear end of the cover member 670 has an R shape. This is a device for preventing the support plate 603 from colliding with the bottom plate 11b and closing the front door 12 smoothly when closing the front door 12 with respect to the housing 11.

Next, the support fitting 800 will be described in detail with reference to FIGS. 7 to 10 and 15 to 18. 15 is a left side view of the support fitting 800, FIG. 16 is a front view, FIG. 17 is a right side view, and FIG. 18 is a rear view.

The support fitting 800 includes a vertically long mounting plate 801 as a mounting portion fixed to the inside of the right side plate 11e of the housing 11.

The front edge of the mounting plate 801 is formed so that substantially the entire area is bent toward the outside of the housing 11. This is a device for smoothly closing the front door 12 without closing the front edge of the mounting plate 801 with the locking device 600 when closing the front door 12 with respect to the housing 11.

The mounting plate 801 is provided with a pair of upper and lower receiving fittings 803 and 804 that engage with the hook members 611 and 612 of the locking device 600.

The receiving metal fittings 803 and 804 are provided with substantially flat plate-shaped main body portions 803a and 804a which are arranged in contact with the mounting plate 801. The receiving fittings 803 and 804 form the movable engaging portion in this embodiment.

The main body portions 803a and 804a include vertically long vertical piece portions 803b and 804b, upper piece portions 803c and 804c extending forward from the upper end portions of the vertical piece portions 803b and 804b, and lower end portions of the vertical piece portions 803b and 804b. It is provided with lower piece portions 803d and 804d extending forward from the portion, and is formed in a generally U-shape in a side view, which is concave toward the front.

Guide holes 803e and 804e are formed at substantially central portions of the vertical piece portions 803b and 804b. The guide holes 803e and 804e are elongated holes extending in the vertical direction. The shaft pins 805 and 806 inserted into the guide holes 803e and 804e from the inside of the housing 11 are fixed to the mounting plate 801. As a result, the receiving fittings 803 and 804 can be slid vertically. In the sliding range of the receiving fittings 803 and 804, the position where the upper edge portion of the guide holes 803e and 804e abuts the shaft pins 805 and 806 corresponds to the engagement portion locking side specific position in the present embodiment. The position where the lower edge portions of 803e and 804e contact the shaft pins 805 and 806 corresponds to the engagement portion unlocking side specific position.

Engagement portions 803f and 804f protruding inward of the housing 11 are provided at front edge portions of the vertical piece portions 803b and 804b. The hook members 611 and 612 are locked to the engaging portions 803f and 804f.

Protruding pieces 803g and 804g protruding toward the inside of the housing 11 are provided at the front end portions of the upper piece portions 803c and 804c. Of these, the projection piece 803g of the upper receiving metal piece 803 functions as an operating portion that engages with the lock member 660 as described later.

Hook portions 803h and 804h are provided below the vertical piece portions 803b and 804b. Then, the hook portions 803h and 804h are hooked with one ends of the coil springs C4 and C5 as the movable engaging portion biasing means, and the other ends are hooked onto the hook portions 807 and 808 provided on the mounting plate 801. There is. The receiving members 803 and 804 are normally urged downward by the tensile force of the coil springs C4 and C5.

Further, the mounting plate 801 is provided with restriction protrusions 809 and 810 at positions below the receiving fittings 803 and 804. Therefore, the receiving metal fittings 803 and 804 are normally held at the reference position where the lower end portions of the receiving metal fittings 803 and 804 are in contact with the restriction protrusions 809 and 810 (see FIG. 15 ). Further, in this state, the upper edge portions of the guide holes 803e, 804e are in contact with the shaft pins 805, 806.

On the other hand, at the rear edge of the mounting plate 801, flange portions 811 and 812 protruding inward of the housing 11 are provided in predetermined vertical sections corresponding to the receiving metal fittings 803 and 804 and the coil springs C4 and C5. ing. On the other hand, a rib that is bent toward the inner side of the housing 11 at a substantially central portion in the front-rear direction of the mounting plate 801 so as to correspond to the engaging portions 803f and 804f so that a part of itself is notched. 813 and 814 are provided.

The flange portions 811 and 812 and the ribs 813 and 814 have a function as a guide portion that enhances the stability of the mounting state of the receiving metal fittings 803 and 804 and a stability of the sliding operation of the receiving metal fittings 803 and 804. There is. Therefore, the receiving fittings 803 and 804 are restricted from moving in the front-rear direction (the left-right direction in FIG. 15) by the flange portions 811 and 812 and the ribs 813 and 814, and the left-right direction (the left-right direction by engaging the shaft pins 805 and 806). The movement in the horizontal direction (Fig. 16) is restricted, and the slide can be performed in the vertical direction. Further, the ribs 813 and 814 have a function as a support means that supports the engaging portions 803f and 804f when the hook members 611 and 612 engage with the engaging portions 803f and 804f. That is, the ribs 813 and 814 can increase the rigidity of the engaging portion, and enhance the stability of the hook members 611 and 612 and the engaging portions 803f and 804f in the engaged state, and thus in the locked state of the front door 12. Therefore, in the present embodiment, in order to further secure the above effect, the engaging positions of the hook members 611 and 612 in the left-right direction are set within the overlapping range of the ribs 813 and 814 and the engaging portions 803f and 804f. It is set.

Further, a mounting base portion 819 that protrudes toward the inside of the housing 11 is provided at the rear edge of the mounting plate 801 at a position above the upper receiving metal piece 803. An opening detection switch 820 is attached to the attachment base 819.

The opening detection switch 820 is attached so that the switch portion 820a faces forward. With this configuration, when the front door 12 is in the closed state, the switch portion 820a is pressed by the rib 667 on the locking device 600 side so that the switch portion 820a is retracted into the switch body (see FIG. 22). On the other hand, when the front door 12 is opened, the switch portion 820a projects from the switch body by being separated from the rib 667 on the locking device 600 side (see FIG. 15).

The open detection switch 820 outputs an ON signal when the switch unit 820a is in the protruding state, and outputs an OFF signal when the switch unit 820a is in the retracted state. That is, when the front door 12 is opened, the open detection switch 820 outputs an ON signal to the main controller 131. Main controller 131 recognizes that front door 12 has been opened based on this ON signal.

Next, the operation of the locking device 600 and the support fitting 800 will be described in detail. In the locked state of the locking device 600 and the support fitting 800 as shown in FIG. 22, the first sliding rod 610 takes the reference position, so that the hook members 611, 612 move the receiving fittings 803 as shown in FIG. The front side door 12 is locked by being locked on the back side of the engaging portions 803f and 804f of 804.

When the front door 12 is locked in the housing 11, the upper sliding member 803 is prevented from sliding upward by the lock member 660. More specifically, the stopper portion 660e of the lock member 660 is located directly above the protruding piece 803g of the receiving metal fitting 803, and when the stopper portion 660e is brought into contact with the stopper portion 660e, the sliding movement of the receiving metal fitting 803 upwards except for the play width. Substantially regulated. That is, the position where the metal fitting 803 contacts the stopper portion 660e of the lock member 660 is the displacement limit position of the metal fitting 803 in the locked state.

Further, in the closed state of the front door 12, as described above, the engagement of the cam plate 720 of the cylinder lock 700 with the stopper portion 731 causes the sliding displacement of the first sliding rod 610 upward, and thus the hook member. Displacement of 611 and 612 in the unlocking direction is substantially restricted except for the play width. That is, the position of the hook member 611 when the stopper portion 731 of the first sliding rod 610 is in contact with the cam plate 720 of the cylinder lock 700 is the displacement limit position of the hook member 611 in the locked state.

Then, when the front door 12 is opened, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated clockwise when viewed from the front side (see FIG. 1) of the slot machine 10. This operation corresponds to the specific operation in this embodiment. As a result, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b comes into contact with the upper edge portion of the lower engagement hole 726 of the first sliding rod 610 [see FIG. 21(b)]. However, since FIG. 21B is a view seen from the rear side of the slot machine 10, the rotation direction of the cam plate 720 is the counterclockwise direction.

Thereafter, as the cam plate 720 is further rotated, the lower engagement claw 720b pushes the first sliding rod 610 upward against the tensile force of the coil spring C1. At this time, since a space for displacing the lower engaging claw 720b upward is secured in the upper part of the lower engaging hole 728 of the second sliding rod 620, through which the lower engaging claw 720b is inserted, the first sliding member 720b is secured. In the process of pushing up the moving rod 610, the lower engagement claw 720b does not abut the second sliding rod 620, so that its operation is not hindered. Of course, in this case, since the cam plate 720 slides the first sliding rod 610, the stopper portion 731 does not act.

When the first sliding rod 610 slides upward, as shown in FIG. 24, the hook members 611 and 612 rotate to release the engagement of the receiving fittings 803 and 804 with the engaging portions 803f and 804f. .. That is, the hook members 611 and 612 and the receiving fittings 803 and 804 are disengaged. As a result, the locking device 600 and the support fitting 800 are unlocked, and the front door 12 can be opened. Therefore, the relative displacement amount in the up-down direction between the head portions 611b and 612b of the hook members 611 and 612 and the engaging portions 803f and 804f of the receiving metal fittings 803 and 804 is the relative displacement amount required to be in the disengaged state. is there.

Further, when the force of the hand operating the key K is relaxed when the front door 12 is opened, the first sliding rod 610 is pulled down by the tensile force of the coil spring C1 and returns to the reference position. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

As described above, in the present embodiment, when the key K is not inserted into the key hole 702 of the cylinder lock 700, the sliding of the first sliding rod 610 is restricted, but the front door is in the open state. The lock 12 is designed so that it can be locked without using the key K.

More specifically, as shown in FIG. 25, when the front door 12 is closed from the opened state of the front door 12 in which the locking device 600 and the support fitting 800 are unlocked, the hook members 611 and 612 first move. The inclined portions 611c and 612c of the head portions 611b and 612b come into contact with the lower sides of the engaging portions 803f and 804f of the metal fittings 803 and 804 (see FIG. 26).

At this time, as described above, the displacement of the first sliding rod 610, and thus the hook members 611, 612, in the unlocking direction is substantially restricted except for the play width, so that the front door 12 is further closed. As shown in FIG. 27, the hook members 611 and 612 are slightly pivotally displaced, but are not largely pivotally displaced, and maintain a slightly pivoted state at the displacement limit position in the locked state. For this reason, the metal fittings 803 and 804 mainly slide upward against the tensile force of the coil springs C4 and C5.

Then, as shown in FIG. 27, the protrusion 803g at the front end of the upper piece 803c of the upper receiving metal piece 803 that has slid upward contacts the stopper 660e of the lock member 660 from the front. As a result, the lock member 660 is pushed by the receiving fitting 803 to rotate, and the lower side is displaced rearward. That is, the lock member 660 does not get in the way when the front door 12 is closed. Note that this position (state) corresponds to the second position (second state) of the lock member 660 in this embodiment.

After that, when the heads 611b and 612b of the hook members 611 and 612 pass over the engaging portions 803f and 804f of the receiving fittings 803 and 804, the engaging portions 803f and 804f are locked by the tensile force of the coil springs C4 and C5. , 612a, the receiving fittings 803, 804 return to their original positions, and the heads 611b, 612b of the hook members 611, 612 are locked to the engaging portions 803f, 804f of the receiving fittings 803, 804 ( (See FIG. 23). Therefore, at this time, the relative displacement amount of the head portions 611b and 612b of the hook members 611 and 612 and the engaging portions 803f and 804f of the receiving metal fittings 803 and 804 in the vertical direction is the head portion 611b and 612b. , 804f, that is, the relative displacement required to close the front door 12.

When the receiving fittings 803, 804 return to their original positions, the lock member 660 also returns to its original posture, and the stopper portion 660e of the locking member 660 is positioned directly above the protruding piece 803g of the upper piece portion 803c of the receiving fitting 803. It becomes a state. As a result, the locking is completed, the opening of the front door 12 is regulated, and the sliding of the receiving metal fitting 803 by the lock member 660 is substantially regulated except for the play width, that is, It will be in a locked state (locked state).

Next, the reset operation will be described in detail. In the closed state of the front door 12, the second sliding rod 620 takes the reference position, so that the second protruding piece 622 is inserted between both elements of the reset detection sensor 640 as described above.

Then, when performing the resetting operation in the closed state of the front door 12, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated counterclockwise as viewed from the front side of the slot machine 10. As a result, the cam plate 720 rotates in the same direction, and the upper engaging claw 720a comes into contact with the upper edge portion of the upper engaging hole 727 of the second sliding rod 620 [see FIG. 21(c)]. However, since FIG. 21C is a view seen from the back side of the slot machine 10, the rotation direction of the cam plate 720 is the clockwise direction.

Thereafter, as the cam plate 720 is further rotated, the upper engagement claw 720a pushes down the second sliding rod 620 against the tensile force of the coil spring C2. At this time, since a space for displacing the upper engaging claw 720a downward is secured in the lower portion of the upper engaging hole 725 of the first sliding rod 610, through which the upper engaging claw 720a is inserted, the second sliding bar 720a is secured. In the process of pushing down the moving rod 620, the upper engaging claw 720a does not abut the first sliding rod 610, so that its operation is not hindered.

When the second sliding rod 620 slides downward, the second projecting piece 622 comes out between both elements of the reset detection sensor 640, the reset detection sensor 640 detects this, and a detection signal to the main control device 131 described later. Is output. Main controller 131 can recognize that a reset operation has been performed based on this detection signal. As a result, an error state such as a hopper error can be reset without opening the front door 12.

Then, when the force of the hand that operates the key K is released, the second sliding rod 620 is pulled upward by the tensile force of the coil spring C2 and returns to the reference position. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

On the other hand, when the front door 12 is open, the same resetting operation as described above can be performed by manually operating the first protruding piece 621 and sliding the second sliding rod 620 downward. As described above, the slot machine 10 has a backup function for various data, and holds the state at the time of power failure even if a power failure occurs, and at the time of power recovery (recovery) It is possible to return to the state of. Therefore, when the power is shut off in the normal procedure like when the game hall is closed, the state before the power is shut off is stored and retained. However, for example, when the power switch 122 is turned on while pressing the first projection piece 621, the backup data is saved. It is supposed to be reset.

As described above in detail, in the present embodiment, when the key K is not inserted in the cylinder lock 700, the cam plate 720 and the stopper portion 731 are engaged to slide the first sliding rod 610 upward. The dynamic displacement, and thus the displacement of the hook members 611 and 612 in the unlocking direction is substantially restricted except for the play width.

Further, by providing the lock member 660, when the front door 12 is closed, the displacement of the receiving fitting 803 in the unlocking direction is substantially restricted except for the play width.

Thereby, in the locked state, an external force is temporarily applied to the hook member 611 and the receiving metal fitting 803 by using a wire rod or the like, and the hook member 611 and the receiving metal fitting 803 are displaced in the unlocking direction to make the engaging state of the both illegal. Even if it is attempted to release the front door 12, the front door 12 is not allowed to open because the engaged state of the both is maintained. Of course, in the present embodiment, even when both of them are simultaneously displaced to the displacement limit position in the locked state, the engaged state of both is maintained, so the defense performance against unauthorized unlocking is very high.

Further, since the lock member 660 has a configuration that does not interlock with the operation of the cylinder lock 700 in response to an operation by the key K, that is, a configuration that does not interlock with the hook members 611, 612, the first sliding rod 610, etc. Even if the hook members 611 and 612 and the first sliding rod 610 are tampered with without using them, the stress is not transmitted to the lock member 660. That is, since the unlocked state cannot be achieved only by an unauthorized operation on the hook members 611, 612, the first sliding rod 610, etc., the defense performance against unauthorized unlocking is significantly improved.

On the other hand, by operating the cylinder lock 700 with the key K, the hook members 611 and 612 are displaced in the unlocking direction, and the relative displacement amount between the hook members 611 and 612 and the receiving fittings 803 and 804 is equal to or more than a predetermined amount. When obtained, both are in a disengaged state, and opening of the front door 12 is allowed.

In the configuration in which the displacement of the hook members 611 and 612 is restricted when the key K is not inserted in the cylinder lock 700 as described above, if the receiving metal fittings 803 and 804 are fixed, the key K is not locked. When the front door 12 is closed without using the hook members 611 and 612, the hook members 611 and 612 collide with the receiving fittings 803 and 804, and the impact is relatively large. Problems such as deformation and damage may occur. In this respect, in the present embodiment, since the receiving metal fittings 803 and 804 are configured to be displaced, even if the displacement of the hooking members 611 and 612 is restricted, the hooking members 611 and 612 and the receiving metal fittings 803 and 804 are displaced. Since the relative displacement amount equal to or more than the predetermined amount is secured, the above-mentioned problem is unlikely to occur. Therefore, when closing the front door 12, it is not necessary to operate the cylinder lock 700 with the key K, which is highly convenient.

Further, when the front door 12 is closed, the hook members 611 and 612 and the receiving metal fittings 803 and 804 are brought into contact with each other and displaced in the unlocking direction. When the front door 12 is closed, the lock member 660 is automatically changed by the contact of the receiving metal fitting 803 and is returned to the original state after the hook member 611 and the receiving metal fitting 803 are engaged. Further convenience can be improved.

In addition, since both of the hook members 611 and 612 and the receiving fittings 803 and 804 are displaceable, the load applied to each of them when they contact each other can be dispersed and reduced. As a result, it is possible to reduce the occurrence of defects such as deformation and damage of the hook members 611 and 612. In order to obtain such an effect with a configuration in which only one side is displaceable, a coil spring C1 or the like having a relatively weak biasing force may be used. If done, the hook members 611, 612, etc. may be easily displaced in the unlocking direction. In this respect, according to the present embodiment, since the coil springs having a strong biasing force are used to some extent, the load is distributed to both the hook members 611 and 612 and the receiving metal fittings 803 and 804. It is possible to reduce the impact force applied individually.

It should be noted that the present invention is not limited to the contents described in the above embodiment, and may be carried out as follows, for example.

(A) In the above embodiment, when the front door 12 is closed, the hook members 611 and 612 and the receiving fittings 803 and 804 are brought into contact with each other and displaced in the unlocking direction, which requires closing of the front door 12. The configuration is such that the relative displacement amount of both can be obtained. Not limited to this, when closing the front door 12, the hook members 611 and 612 do not substantially displace, and only the receiving fittings 803 and 804 displace in the unlocking direction to close the front door 12. The configuration may be such that the required relative displacement amount between the two can be obtained. Specific examples thereof will be described below with reference to FIGS. 28 to 32, which are partial enlarged views showing the lock member 660, the upper hook member 611 related thereto, and the receiving metal fitting 803. However, the same components as those in the above embodiment are designated by the same reference numerals, detailed description thereof will be omitted, and different components will be described in detail.

In order to realize the above configuration, in the present embodiment, as shown in FIG. 28 and the like, the vertical length of the guide hole 803e of the receiving metal fitting 803 is set to be longer than that in the above-described embodiment, and the receiving metal fitting 803 slides. Expanding the range of motion.

In the locked state of the locking device 600 and the support fitting 800, the hook member 611 is maintained in a substantially horizontal state as shown in FIG. 28 by the biasing force (tensile force) of the coil spring C1 as in the above embodiment. As a result, the hook member 611 is locked on the back side of the engaging portion 803f of the receiving metal fitting 803, and the opening of the front door 12 is restricted. The sliding of the receiving fitting 803 upward is restricted by the lock member 660.

Further, when the front door 12 is closed, the cam plate 720 of the cylinder lock 700 and the stopper portion 731 are engaged with each other, whereby the first sliding rod 610 is slid upward and the hook member 611 is unlocked. The displacement to is regulated.

When the front door 12 is opened by the key K and the first sliding rod 610 slides upward against the biasing force of the coil spring C1, the hook member 611 rotates as shown in FIG. The engagement with the engaging portion 803f of the receiving metal fitting 803 is released. This allows the front door 12 to be opened.

On the other hand, when locking, as shown in FIG. 30, when the front door 12 is closed from the open state of the front door 12 in which the locking device 600 and the support fitting 800 are unlocked, as shown in FIG. As shown in FIG. 11, first, the inclined portion 611 c of the head portion 611 b of the hook member 611 contacts the lower side of the engaging portion 803 f of the receiving metal piece 803.

In the present embodiment, the biasing force of the coil spring C1 that biases the hook member 611 is set to be stronger than the biasing force of the coil spring C4 that biases the receiving fitting 803. Therefore, when the front door 12 is further closed, the hook member 611 is hardly rotationally displaced due to the difference between the urging force of the coil spring C1 and the urging force of the coil spring C4, and maintains the same state as the locked state. At the same time, only the receiving fitting 803 slides upward preferentially against the biasing force of the coil spring C4. Then, the relative displacement amount required for the head portion 611b of the hook member 611 to move over the engaging portion 803f of the receiving metal fitting 803, that is, the relative displacement amount required for closing the front door 12 is obtained.

As shown in FIG. 32, the protrusion 803g at the front end of the upper piece 803c of the receiving fitting 803 that has slid upward contacts the operated portion 660f of the lock member 660. As a result, the lock member 660 is pushed by the receiving fitting 803 to rotate. The actuated portion 660f is added along with the expansion of the sliding range of the receiving fitting 803, and is integrally formed at the end of the stopper portion 660e. By forming the acted part 660f, it is possible to prevent the upper piece part 803c of the receiving fitting 803 from getting into the upper side of the stopper part 660e, and to operate the lock member 660 appropriately and smoothly. Further, in the present embodiment, due to the difference in the operation of the hook member 611 and the receiving metal fitting 803 from the above-described embodiment, the formation range of the guide hole 660c of the lock member 660 (the rotation range of the lock member 660), the rib 813, and the like. Settings such as vertical length have been changed. For example, as shown in FIG. 32 and the like, in a state where the hook member 611 is maintained in a substantially horizontal state, up to the height position of the upper end portion of the head portion 611b (inclined portion 611c) of the hook member 611, the receiving metal fitting 803 is placed. The formation range of the guide hole 660c of the lock member 660, the vertical length of the guide hole 803e of the receiving fitting 803, and the like are set so that the lower end of the engaging portion 803f can be displaced.

After that, when the engaging portion 803f of the receiving fitting 803 crosses over the head portion 611b of the hook member 611, the engaging portion 803f enters the locking recess 611a by the biasing force of the coil spring C4, and the receiving fitting 803 is restored to its original position. Returning to the position, the head portion 611b of the hook member 611 is locked to the engaging portion 803f of the receiving fitting 803 (see FIG. 28).

When the receiving metal fitting 803 returns to the original position, the lock member 660 also returns to the original posture, and the stopper portion 660e of the lock member 660 is positioned immediately above the protruding piece 803g of the upper piece portion 803c of the receiving metal fitting 803. Become. As a result, the locking is completed, the opening of the front door 12 is restricted, and the sliding of the receiving metal fitting 803 by the lock member 660 is substantially restricted except for the play width. ..

With the above configuration, if the receiving member 803 is displaceable in the unlocking direction using a wire rod or the like and the engagement state with the hook member 611 is to be released illegally, at least the regulation by the lock member 660 is required. It is necessary to perform two types of operations in combination, such as performing a displacement operation in the unlocking direction of the receiving metal fitting 803 after or simultaneously with the release operation. Therefore, a complicated operation of hooking a wire rod or the like on a plurality of members provided in close proximity such as the receiving metal fitting 803 and a lock member 660 for controlling the metal fitting 803, or a complicated operation of operating the hooked wire rod or the like in different directions. Since the operation must be performed, the unauthorized unlocking operation becomes difficult. As a result, the defense performance against unauthorized unlocking can be enhanced as in the above embodiment.

Further, when locking is performed, only the receiving metal fitting 803 needs to be displaced, so it is necessary to perform a complicated design in consideration of the relationship between the receiving metal fitting 803 and the hook member 611 such as the relative displacement. It is also easy to deal with various design changes on the hook member 611 side.

In the present configuration, the hook member 611 is different from the hook member 611 when the locking is performed by making the biasing force of the coil spring C1 that biases the hook member 611 different from the biasing force of the coil spring C4 that biases the receiving fitting 803. Maintain the reference posture, and only the receiving fitting 803 is displaced. However, the present invention is not limited to this, and there may be little play between the stopper portion 731 of the first sliding rod 610 and the lower engaging claw 720b of the cam plate 720, and the hook member 611 may be configured to maintain the reference posture. Further, if the stopper portion 731 of the first sliding rod 610 and the lower engaging claw 720b of the cam plate 720 are in contact with or substantially in contact with each other, the hook member 611 can be hardly moved. Can be maintained.

(B) The configurations of the hook members 611 and 612 are not limited to the above embodiment. For example, a structure may be adopted in which the hook members 611 and 612 are integrally formed with the first sliding rod 610 and are slidably displaced in the vertical direction.

(C) The numbers of the hook members 611 and 612, the receiving fittings 803 and 804, and the lock members 660 corresponding to these are not limited to those in the above embodiment.

For example, the hook members 611 and 612 and the receiving fittings 803 and 804 may be provided in a pair or in three or more pairs.

Further, in the above-described embodiment, the lock member 660 is provided only corresponding to the upper receiving fitting 803, but it may be provided only corresponding to the lower receiving fitting 804, or both receiving fittings 803 and 804. May be provided corresponding to each. In order to improve the defense performance against unauthorized unlocking, when there are a plurality of receiving fittings, it is preferable to provide the lock member 660 corresponding to each. However, if provided corresponding to at least one, the defense performance against unauthorized unlocking can be sufficiently exerted. In particular, if the lock member 660 is provided corresponding to the upper receiving bracket 803 as in the above-described embodiment, it is necessary to stand up from the seat when performing a cheating act in a game hall or the like, and thus it is fraudulent. Highly effective in deterring actions.

Further, in the above embodiment, the locking member 660 as the movable engaging portion restricting means (restricting member) is provided in the locking device 600, but it may be provided in other parts such as the front door 12 and the housing 11. Good.

(D) The configurations of the receiving fittings 803 and 804 are not limited to the above embodiment. For example, the receiving metal fittings 803 and 804 may be configured to move up and down and to be rotationally displaceable.

Further, in the above embodiment, when the front door 12 is closed, the receiving metal fittings 803 and 804 are displaced in the unlocking direction by contacting the hook members 611 and 612. The present invention is not limited to this, and the metal fittings 803 and 804 may be displaced by the electric driving means when the front door 12 is opened and closed, for example. As a specific example, for example, a configuration in which a solenoid or the like is controlled according to the detection result of the opening detection switch 820 or the opening operation detection sensor 630 to displace the receiving metal fittings 803 and 804 can be cited.

(E) The structure of the lock member 660 is not limited to the above embodiment. For example, in the above-described embodiment, when the front door 12 is closed, the lock member 660 is automatically rotationally displaced by the contact of the receiving fitting 803, and is returned to the original state after the hook member 611 and the receiving fitting 803 are engaged. Has become. On the other hand, for example, a lock member that slides in a substantially horizontal direction may be adopted. Further, instead of being displaced due to contact with the receiving fitting 803, for example, when the front door 12 is opened and closed, the first state in which the displacement of the receiving fitting 803 is restricted by the electric driving means, and the hook member 611 and the receiving fitting 803. May be changed to a second state that allows the engagement state of the. As a specific example, for example, a configuration in which a solenoid or the like is controlled according to the detection results of the opening detection switch 820 and the opening operation detection sensor 630 to displace the lock member can be cited. When such a configuration is adopted, the movement of the solenoid or the lock member is restricted so that the solenoid or the lock member is not displaced by an unauthorized unlocking operation without using the key K. Is preferably provided. For example, when the lock member can be displaced only through the plunger driven by the excitation/non-excitation of the solenoid or the link member interlocked with the plunger, and the wire member or the like is hooked on the lock member to illegally displace the lock member. As an example, a configuration example in which the lock member is not displaced by being regulated by a plunger or a link member is given. Further, by providing a cover member or the like for covering the solenoid to prevent the wire rod or the like from being caught on the plunger or the link member, it is possible to enhance the defense performance against fraudulent acts.

(F) The cylinder lock 700 of the above embodiment is in the locked state when the key K is not inserted, and the cam plate 720 cannot be displaced. By the engagement of the cam plate 720 in the locked state and the stopper portion 731, the upward sliding displacement of the first sliding rod 610 and the displacement of the hook members 611 and 612 in the unlocking direction is restricted. .. Not limited to this, a cylinder lock different from the cylinder lock 700 may be adopted. For example, a cylinder lock that does not displace the cam plate 720 even when the key K is not inserted may be used. However, in this case, the hook members 611 and 612 are provided in order to enhance defense control against an unauthorized unlocking operation directly performed on the hook members 611 and 612 and the first sliding rod 610 without using the key K. Alternatively, it is preferable to provide another restricting means for restricting the displacement of the first sliding rod 610. Of course, depending on the balance with the receiving fittings 803 and 804, the engaging state with the receiving fittings 803 and 804 can be achieved even if an unauthorized unlocking operation without using the key K is performed at the time of locking without providing a regulation means. It is possible to have a configuration in which is not released.

Of course, the lock member is not limited to the cylinder lock, but may be operated by using a key such as a card key.
