The “locking device” may be locked by the “lock” locking operation, or may be automatically locked by closing the door like a latch lock.

The “lock” only needs to unlock at least the locked front door (3) as described above. For example, when a predetermined key is inserted into the keyhole and rotated, the cam (91) rotates, and the engaged portion and the engaged portion (for example, the hook (lower door hook 80)) and the locking piece (housing) are locked. Any of the body locking pieces 110)) can be moved in the disengagement direction to disengage and unlock.
In addition, as a gaming machine, a control device called a board on which various electronic components such as a CPU, a ROM, and a RAM are mounted, a gaming device such as a reel unit (20), a power supply device (4), a payout device (hopper unit 5). ) And the like.

  In the present invention, the side door (40A) on the opposite side of the shaft support (19) of the front door (3) is attached to the inside of the side plate (40A) so as to be swingable in the horizontal direction via the swing shaft (51). While always biased in the direction to return to the origin position, when the front door (3) is closed, the front door (3) and the housing ( A shielding plate (50) is provided to shield the joint with 1) from the inside. In addition, an abutting portion (abutting portion) on which the shielding plate (50) at the origin position can come into contact with the opposite side of the shaft support portion (19) inside the housing with the closing operation of the front door (3). A member 60) is provided. Further, the lock (90) is provided with a contact portion (swinging protrusion 93) capable of contacting at least a part of the shielding plate (50) at the time of unlocking.

Here, when the front door (3) is divided into upper and lower parts, for example, the shielding plate (50) may be provided only on the upper door (30) or only on the lower door (40). Of course, it may be provided on both the upper door (30) and the lower door (40). The “origin position” of the shielding plate (50) is the position (horizontal rotation position) of the shielding plate (50) in a normal state (a state where the contact portion (93) is not in contact). The shielding plate (50) is constantly urged in a direction to return to the original position by a spring (52), for example. A stopper (T) for stopping the shielding plate (50) at the origin position may be provided.
The abutting portion (60) is a door closing regulating means provided on the side opposite to the shaft supporting portion of the housing (1), and the front door (3) is not further closed by colliding with the shielding plate (50). It is for doing so. The butting portion (60) may be a part of the member constituting the housing (1) or a device installed in the housing (1), or the shielding plate (50) at the origin position when the door is closed. The member provided in the position which collides. For example, an angle member provided on the side plate (16) or the bottom plate (15) of the housing (1) can be used.

The “contact portion” may be, for example, a protrusion provided on the cam (91) that rotates in accordance with the unlocking operation. The contact portion (93) may be formed so as to be in contact with the shielding plate (50) and press the shielding plate (50) at least when performing the unlocking operation. (93) may be in contact with the shielding plate (50).
Then, the shielding plate (50) is pressed by the abutment portion (93) when the lock (90) is unlocked by using a predetermined key, and the swing shaft (51) is centered. When the front door (3) is closed while the shielding plate (50) is rotated from the original position by the unlocking operation of the lock (90), the shielding plate ( 50) and the abutting part (60) do not interfere with each other, the front door (3) can be closed to a lockable position, and the front door ( When 3) is closed, at least a part of the shielding plate (50) and the abutting part (60) collide so that the front door (3) cannot be closed to a lockable position. It is characterized by being formed.

(Function)
In the present invention, when closing the opened front door (3), specifically, for example, a predetermined key is inserted into the keyhole (44) while unlocking the lock (90). The front door (3) is rotated in the closing direction while being rotated in the unlocking direction. Along with the unlocking operation, the shielding plate (50) is pressed by the contact portion (93) and rotates around the swing shaft (51), and is located at the door outer side or the door center side from the origin position. Therefore, the front door (3) can be closed to a lockable position without interference between the shielding plate (50) and the abutting portion (60).
On the other hand, when the front door (3) is closed without unlocking the lock (90), the shield (50) is at the origin position, so the front door (3) is turned in the closing direction. When moved, the shielding plate (50) collides with the abutting portion (60) before the front door (3) is completely closed. For example, the back surface (50B) of the shielding plate (50) or a part of the back surface (the projecting portion 55) collides with the front surface (60A) of the upright plate-shaped butting portion (60). For this reason, the front door (3) cannot be further rotated in the closing direction, and as a result cannot be locked. Therefore, for example, if the front door (3) is opened without using a regular key, the door can be opened but cannot be closed. Open door is discovered.

In addition, with the front door (3) slightly opened, even if a foreign object such as a wire enters from the gap with the housing (1), it is obstructed by the shielding plate (50) and reaches the internal device. I can't. For the shielding plate (50), it is preferable to provide a stopper (T) that restricts rotation to the door center side (inside the housing).
The invention described in claim 1 is characterized by the following points in addition to the above-described characteristic points.
That is, the rear portion of the shaft support (19) and a side face of the front SL front door (3) (side plate 40A), said housing (1) and the junction of the front door (3) at the time of closing A cover part (40B) that covers from the outside of the side of the housing is provided, and this cover part (40B) is in a state where the front door cannot be locked when the shielding plate (50) is in contact with the abutting part (60). 1 has a depth dimension capable of covering a gap between the housing (1) and the front door (3).

In the present invention, in addition to the shielding plate (50) as an anti-fraud plate, a cover for concealing the seam is provided at a portion of the front door (3) which is a joint with the housing (1), and the front door (3) In addition to preventing foreign matter from entering from the outside in a slightly opened state, it is impossible to close the door by pressing the shielding plate (50) from the outside.
In the present invention, the cover (40B) covers the side surface of the housing (1) in a state where the shielding plate (50) is in contact with the abutting portion (60), so the front door (3) and It is impossible to allow a foreign object to enter through the gap with the housing (1) and to push and turn the shielding plate (50).
(Claim 2 )
The invention described in claim 2 is characterized by the following points in addition to the features of the invention described in claim 1 described above.

That is, in the invention according to claim 2 , in the abutting portion (60), there is no gap between the back surface (Q) of the cover portion (50) and the front surface (R) of the housing (1). When the front door (3) is closed until the shielding plate (50), which has been rotating away from the origin position in the direction away from the abutment section (60), returns to the origin position, it contacts the abutment section (60). It is arrange | positioned in the position which can maintain the distance which does not carry out.
Here, “maintaining a distance that does not contact the abutting portion (60)” specifically means that the back surface (50A) of the shielding plate (50) does not reach the front surface (60A) of the abutting portion (60). This also includes that the side surface (outer surface 50B) of the shielding plate (50) returned to the origin position does not come into contact with the side surface (60B) of the abutting portion (60).

In the present invention, even when the shielding plate (50) is struck by a foreign object and is not at the origin position, it is between the back surface (Q) of the cover (40B) and the front surface (R) of the housing (1). When the front door (3) is closed until there is not enough space for foreign objects to enter (that is, until the door does not close if the foreign objects are not removed), it comes into contact with the shielding plate (50) that returns to the home position by the biasing force. The position (50) is in an inaccessible positional relationship.
Therefore, even if foreign matter is inserted just before the door is closed, if the foreign matter is removed to close the door, the shielding plate (50) will return to the home position without contacting the abutting part (50), and the closing operation will continue. If it does, it will collide with an abutting part (50) (refer FIG. 13).

  According to the first aspect of the present invention, the anti-tampering member that prevents foreign substances from entering has an additional function to improve the security of the gaming machine and minimize the trouble to the operations of the gaming store.

In other words, the upper door 30 is unlocked when the lower door 40 is unlocked.If the lower door 40 is opened, the upper door 30 can be opened and closed alone, but the lower door 40 is closed. If it is, it cannot be opened alone.
(Shield 50)
As shown in FIG. 4, the shielding plate 50 has a swing shaft 51 on the center side of the lower door 40 (hereinafter referred to as the door center side) of the mounting plate 40C provided on the back surface of the lower door 40 rather than the cam 91. It is a thin-plate member attached so that rocking is possible through a horizontal direction.

That is, a swinging protrusion abutting portion 53 as shown in FIG. 11 is formed at the upper end portion on the shaft support portion side of the shielding plate 50, and the spring 52 provided on the swinging shaft 51 is always used for the lower door 40. It is biased toward the side plate 40A side (hereinafter referred to as the outside). As shown in FIGS. 5 and 7, the swing protrusion 93 of the cam 91 is always in contact with the shielding plate 50 at the swing protrusion contact portion 53.
Here, as shown in FIGS. 5 and 11, the rocking protrusion abutting portion 53 is a recess provided on the outer surface 50B of the shielding plate 50 (the surface on the side plate 40A side). And as shown in FIG. 11, it is formed in the cross-sectional triangle shape by which the inclination part 53a was formed in the bottom face of a recessed part. When the cam 91 is in the locking position shown in FIG. 8 (the position where the push-down projection 92 does not push down the movable plate 71 of the lower door locking device 70. The position where the key inserted into the key hole 44 is not rotated) The swing projection 93 abuts on the lower end 53b of the swing projection abutting portion 53 (the tip of the surface extending from the lower end of the inclined portion 53a to the outer surface of the shielding plate 50), and the cam 91 is unlocked as shown in FIG. If the push-down projection 92 is at the position where the movable plate 71 of the lower door locking device 70 is pushed down (the position where the key inserted into the keyhole 44 is rotated), the swing projection 93 contacts the swing projection. The upper end portion 53c of the portion 53 (the upper end portion of the inclined portion 53a) is brought into contact with the upper end portion 53c.

  The shielding plate 50 formed as described above swings in the horizontal direction by the rotation of the cam 91 accompanying the unlocking operation. Specifically, in a normal state (when no unlocking operation is performed), the shielding plate 50 is inclined outward as shown in FIG. This is the origin position α of the shielding plate 50. When the cam 91 is rotated in the unlocking direction (the direction in which the push-down projection 92 pushes down the movable plate 71) by the unlocking operation, the tip of the swing projection 93 moves from the lower side to the upper side along the inclined portion 53a. Then, the shielding plate 50 is pushed toward the door center side (the white arrow side in FIG. 6A). As a result, the shielding plate 50 rotates about the swing shaft 51 toward the door center side, and is in a substantially vertical state in plan view as shown by a solid line in FIG.

Further, as shown in FIGS. 4 and 6, in the vicinity of the swinging shaft 51 of the mounting plate 40 </ b> C, the shielding plate 50 is prevented from rotating toward the door center side from the position in a substantially vertical state in plan view. A stopper T is provided. That is, the shielding plate 50 shields the gap between the lower door 40 and the housing 1 from the inside when the lower door 40 is slightly opened as shown in FIG. It also has a function as a fraud prevention plate for preventing mischievous goto acts.
Since the abutting member 60 is provided inside the side plate 16 of the housing 1, the opened lower door 40 remains in a locked state (that is, the key is not inserted into the key hole 44 or the inserted key is not inserted). If the lower door 40 is to be closed without rotating in the unlocking direction), the back surface 50A of the shielding plate 50 abuts against the front surface 60A of the abutting member 60 to lock the lower door 40 as shown in FIG. I can't. By being formed in this way, for example, when the lower door 40 is illegally unlocked without using a predetermined key, the door can be opened but cannot be closed. Due to an error or the like, the game cannot be performed. As described above, the shielding plate 50 has a function as a door closing restricting means for preventing the lower door 40 from being closed unless a key is used in addition to the function as the above-described fraud prevention plate. .

In the above example, the spring 52 is provided on the swing shaft 51. However, as shown in FIG. 12, the spring hooking portion 54 provided on the outer surface of the shielding plate 50 and the spring fixing portion provided on the fixing member 75 are provided. A spring 52 may be interposed between 75C and 75C. Further, as long as the shielding plate 50 can always be urged outward, the form and the mounting position of the spring 52 are not limited to those illustrated.
(Opening / closing the lower door 40)
Next, opening and closing of the lower door 40 will be described in relation to the action of the shielding plate 50.
First, in a state where the lower door 40 is closed and locked, the shielding plate 50 is biased outward, so that it is inclined outward as indicated by a two-dot chain line in FIG. Is in contact with the side surface 60B of the abutting member 60. This position is a position inclined slightly inward from the origin position α of the shielding plate 50 (see FIG. 7). At this time, the cam 91 is in the locking position shown in FIG. 8, and the lower door hook 80 is engaged with the housing locking piece 100 as shown in FIG. And in the locked state of the lower door 40, as shown in FIG. 5, the cover part 40B provided in the side plate 40A of the lower door 40 serves as a joint between the lower door 40 and the side plate 16 of the housing 1. The wire is covered from the outside so that a wire or the like cannot enter from the gap between the lower door 40 and the housing 1.

When opening the lower door 40, when a predetermined key is inserted into the keyhole 44 and rotated in the unlocking direction, the cam 91 rotates as shown in FIG. The door hook 80 rotates downward as shown in FIG. 10B, and the engagement with the housing locking piece 100 is released (unlocked). At this time, the shielding plate 50 is pushed toward the center of the door by the swinging projection 93 and is in a substantially vertical state in plan view as shown by a solid line in FIG. If the lower door 40 is rotated in the opening direction in this state, the lower door 40 can be opened.
When closing the opened lower door 40, the key inserted in the key hole 44 is rotated in the unlocking direction, that is, the lower door 40 is rotated in the closing direction while the shielding plate 50 is in the vertical state. . Since the front end portion of the shielding plate 50 is located inside the housing with respect to the side surface 60B of the abutting member 60, the lower door 40 can be closed without the shielding plate 50 and the abutting member 60 interfering with each other.

If the key is returned to the locking position after the lower door 40 is closed, the shielding plate 50 is rotated outward again by the biasing force of the spring 52. The depth dimension of the shielding plate 50 is such that when the door is closed, the back surface 50A is formed on the back side with respect to the front surface 50A of the abutting member 60, so that the outer surface 50B is on the side surface 60B of the abutting member 60. Abutting and stopping rotation (see the two-dot chain line in FIG. 5).
On the other hand, when the lower door 40 is closed without rotating the key in the unlocking direction, since the shielding plate 50 is at the origin position α inclined outward, the back surface 50A of the shielding plate 50 is abutting member as shown in FIG. It collides with the front 60A of 60. For this reason, the lower door 40 cannot be moved to the fully closed position due to the collision between the shielding plate 50 and the abutting member 60, and a gap P is generated between the lower door 40 and the housing 1. Will remain. At this time, the lower door hook 80 is pushed down by the contact between the inclined portion 83 and the housing locking piece 100 and is rotated downward as shown in FIG. Since the lower door 40 cannot move until the locking recess 82 engages with the housing locking piece 100 due to the collision between the shielding plate 50 and the abutting member 60, the lower door 40 cannot be locked.

However, since the cover portion 40B of the lower door 40 has a depth dimension that can cover the gap P from the outside, a wire or the like cannot be inserted from the gap P in the state shown in FIG. . Therefore, it is not possible to close the lower door 40 by pushing the shielding plate 50 from the outside with a wire or the like and rotating it toward the center of the door.
Further, even if the lower door 40 is closed while the shielding plate 50 is pushed by a wire or the like and rotated to the center side of the door, the insert X such as a wire is covered with the covering portion 40B and the housing 1 as shown in FIG. The rear surface 50A of the shielding plate 50 does not reach the position of the abutting member 60 when it is sandwiched between the side plate 16 and the front side so that the door cannot be closed any more. That is, in order to close the lower door 40 in the state shown in FIG. 13, the insert X must be extracted, and the shielding plate 50 returns to the origin position α indicated by the two-dot chain line by the biasing force of the spring 52. When the lower door 40 is closed as it is, the shielding plate 50 collides with the abutting member 60 as shown in FIG.

From the above, the installation position of the abutting member 60 in the depth direction is such that when the lower door 40 is closed, the back surface (Q in FIG. 13) of the cover portion 40B is parallel to at least the front surface (R in FIG. 13). The position where the side surface 60B of the abutting member 60 does not come into contact with the outer surface 50B of the shielding plate 50 in the vertical state is most preferably maintained until the object cannot be inserted into the gap.
Further, since the shielding plate 50 is prevented from rotating to the inside of the housing from a position (see FIGS. 5 and 13) that is substantially vertical in plan view, the shielding plate 50 and the housing 1 as shown in FIG. Even when a foreign object is inserted through the gap of the cover 40B, it is possible to prevent the foreign object from contacting the internal device.

  As described above, in the present embodiment, the shielding plate 50 as an anti-fraud plate that prevents foreign matter from entering through the gap is provided with an additional function as a door closing restricting means. Since the lower door 40 is formed so that it cannot be completely closed and locked unless the cylinder lock 90 is unlocked using a predetermined key due to the shielding plate 50, Even if the lower door 40 is unlocked by unauthorized means without using a key, the lower door 40 cannot be closed thereafter. In addition, since the cover 40B of the lower door 40 covers the gap P between the casing 1 and the lower door 40 caused by the collision between the shielding plate 50 and the abutting member 60, the shielding plate 50 is directly operated. Thus, it is impossible to close the lower door 40.

  Since the slot machine S cannot play a game when the door is half open, even if the door is illegally opened and the internal device is altered, the game cannot be played after all. Therefore, such an illegal act can be hesitant. In addition, when the lower door 40 is left unlocked, it is unnatural to look, so that a store clerk can immediately find a table that has been illegally opened. Further, if the lower door 40 is provided with an open / close detection device so that a predetermined warning is displayed on the slot machine S or a notification is sent to the hall computer when the door is open, an unauthorized opening of the door is possible. This is more preferable because the post-processing can be performed immediately when the error occurs.

On the other hand, if the key is used, the door can be closed by an operation that is almost the same as a normal closing operation. Therefore, as long as the keys are thoroughly managed, there is no need to perform any extra operation when the store clerk of the amusement store opens the door properly, so that troubles in business operations can be minimized.
(Other forms of shielding plate 50, swing projection 93 and abutment member 60)
In the above-described embodiment, the origin position α of the shielding plate 50 is a position inclined outward from the vertical state in plan view, but conversely, the vertical position in plan view is set as the origin position and is moved inward by the unlocking operation. You may make it rotate.
Specifically, as shown in FIG. 14, the shielding plate 50 is always biased toward the cam 91 by the spring 52 (outside), and is rotated outward from the vertical state by the stopper T ′. It does not move. Then, by the rotation of the cam 91 accompanying the unlocking operation, the cam 91 is pushed by the swinging projection 93 and rotates toward the door center (see the two-dot chain line in FIG. 15). When the unlocking operation is stopped, the spring 52 returns to the origin position α.

  On the other hand, as shown in FIG. 15, the abutting member 60 is provided at a position where the shielding plate 50 at the origin position α collides from the front by the closing operation. In this case, the abutting member 60 may be provided on the lower surface of the intermediate plate 12, for example. When the lower door 40 is closed without performing the unlocking operation, the back surface 50A of the shielding plate 50 collides with the front surface 60A of the abutting member 60 as shown by the solid line in FIG. 1 can no longer be closed with a gap P between them and 1 and cannot be locked. On the other hand, when the lower door 40 is closed in the unlocked state, that is, in the state where the shielding plate 50 is rotated to the position indicated by the two-dot chain line in FIG. Since the side surface 50B is located closer to the inside of the housing than the side surface 60B of the abutting member 60, the lower door 40 can be closed to the lockable position without colliding with the abutting member 60.

In the example of FIGS. 14 and 15, the rocking projection abutment portion 53 is not particularly provided on the shielding plate 50, but a reinforcing member is provided so that the contact portion with the rocking projection 93 is not worn or the rocking plate 93 is rocked. The projections 93 may be formed in a shape that allows the shielding plate 50 to rotate smoothly.
In the embodiment described above, the shielding plate 50 is provided only on the lower door 40. However, when the upper door 30 and the lower door 40 are separately formed to be lockable and unlockable, the upper door 30 is provided. Also, a shielding plate similar to the shielding plate 50 may be provided. The same applies when the front door 3 is a single door.
Furthermore, in the above embodiment, the closing operation of the lower door 40 (front door 3) is regulated by the shielding plate 50 colliding with the abutting member 60 provided inside the housing 1. The “abutting portion” that comes into contact with the shielding plate 50 is not limited to the abutting member 60. For example, a shielding plate in which a part of the hopper unit 5 or a hanging portion provided on the intermediate plate 12 is not unlocked is used. May collide with 50.

In addition, a projecting portion 55 as shown in FIG. 16 is provided on the back surface 50A of the shielding plate 50, and the projecting portion abuts against the abutting member 60 so that the closing operation of the lower door 40 is restricted. Good. When formed in this way, when the lower door 40 is closed, the lower part of the shielding plate 50 does not interfere with an overflow tank or the like installed at the lower corner of the lower opening 14.
It goes without saying that the present invention can also be used for gaming machines other than slot machines.
