Description

  The present invention relates to a locking device for a gaming machine such as a pachinko machine, and more particularly to a locking device with improved crime prevention performance.

  A gaming machine such as a pachinko machine installed in an amusement store is generally composed of an outer frame of the gaming machine main body, and an inner frame and a glass frame pivotally supported by the outer frame so as to be opened and closed. It is. A large number of electronic control devices, display devices, etc. are mounted on the middle frame with the game surface, and between the outer frame and the middle frame and between the middle frame and the glass frame so that the player cannot touch them without permission. It is always locked during. On the other hand, it is necessary to open and close the middle frame and the glass frame by unlocking when dealing with problems during the game or adjusting after closing the store. Therefore, a locking device for gaming machines has been required to have a structure that can reliably prevent unauthorized unlocking by an unspecified person and can be easily unlocked by a staff member.

In a conventional gaming machine locking device, a locking member called a “receiver” is provided on one frame to be locked, and a locking member called a “hook” on the other frame that engages and disengages the locking member And a slider member and a cylinder lock for driving the locking member are generally provided. And a staff member came to unlock by operating a cylinder lock using a key. However, in this structure, there is a risk of unlocking with a key and unauthorized operation from the gap in the frame, and various locking devices with improved crime prevention performance have been invented. For example, in the unlocking lock device for a gaming machine disclosed in Patent Document 1, a rod corresponding to a slider member is provided with a restriction pin, and a lock means for locking the restriction pin is further provided as a security measure. In other words, the rod does not move unless the locking means is released, so that it cannot be unlocked even if an external force is applied to the rod by a matching key or unauthorized operation.
JP 11-235451 A

  By the way, in the unlocking lock device of Patent Document 1, the lock means is constituted by a lock pin and an urging means, and a solenoid is used as the release means. In other words, the lock pin is normally projected by the urging means to lock the restriction pin, and when unlocked, the solenoid is energized to suck the lock pin and release the lock. However, in this aspect, unlocking cannot be performed when power is not supplied to the gaming machine, which is extremely inconvenient in handling. Further, the protrusion of the lock pin by the urging means is a simple linear operation, and for example, it cannot be said that it has sufficient security performance against an unauthorized operation of inserting a wire or the like through a gap in the frame.

  The present invention has been made in view of the above background, and can be unlocked even when power is not supplied to the gaming machine, and the gaming machine has a more reliable crime prevention performance against unauthorized operation. Providing the device.

  The gaming machine locking device according to the present invention includes a locking means for mechanically locking an outer frame of the gaming machine and an intermediate frame pivotally supported by the outer frame, and a mechanical unlocking operation of the locking means. In the locking device, the electrical release means includes: a restricting means for prohibiting or permitting the electronic control device; and an electrically releasing means for electrically releasing the prohibited state in which the unlocking operation of the locking means is prohibited by the restricting means. The unlocking operation of the locking means is prohibited by driving the restricting means when the power is turned on, and the unlocking operation of the locking means is allowed by releasing the restricting means when the power is turned off. .

  The locking means includes a locked member provided on one of the outer frame and the middle frame, and a lock provided on the other of the outer frame and the middle frame for locking or releasing the locked member. A member, a cylinder lock that is driven by a mechanical operation, and a connecting member that drives the locking member in conjunction with the operation of the cylinder lock, and the restricting means is engaged with and disengaged from the connecting member. A restricting member having a restricting pin for prohibiting or permitting driving of the connecting member, the electrical release means having a drive shaft that is projected or sucked, and one of the restricting member and the drive shaft has a guide groove; The other of the restricting member and the drive shaft preferably has a guide pin that is movably fitted in the guide groove.

  The present invention is provided with mechanical restriction means for controlling the unlocking operation of a mechanical locking means such as a cylinder lock, and the unlocking prohibition state of the restriction means is released when the electric release means is turned off. It is characterized by that. Therefore, the unlocking operation is prohibited by always turning on the power of the electrical release means to maintain high crime prevention performance, and when the power is not supplied, the operation in the unlocking prohibited state, that is, the so-called locked state is avoided. It has become.

  A conventional structure can be applied to the locking means itself, a locked member called a “receiver”, a locking member called a “hook” that engages and disengages with the locked member, and mechanical operation And a connecting member that is called a “slider member” and transmits the operating force of the cylinder lock to drive the locking member. For example, the member to be locked can be provided on the outer frame, the locking member can be provided on the middle frame, and can be locked by locking them. Furthermore, the connecting member can be provided on the back surface of the middle frame and the cylinder lock can be disposed on the front surface of the middle frame so that the staff can easily operate. Conversely, the locked member may be provided on the middle frame, and the other members may be provided on the outer frame. The connecting member mechanically connects the cylinder lock and the locking member, and can be configured by appropriately combining various mechanical components.

  The restricting means is means for mechanically prohibiting or allowing the unlocking operation of the locking means. As the restricting means, for example, a restricting member that has a restricting pin that engages with and disengages from the connecting member and is pivotably supported can be used. For example, the restriction pin can be configured to be inserted into the restriction groove of the connecting member, inserted into the restriction hole, or in contact with the connecting member to inhibit the unlocking operation.

  As a means for driving the restriction means or the restriction member when the power is turned on and releasing the power when the power is turned off, an electrical release means can be provided. As the electrical release means, for example, an electromagnetic solenoid having a drive shaft that is attracted when the power is turned on and protrudes when the power is turned off can be used. Further, a power switch for turning on and off the power of the electrical release means can be provided. Furthermore, a security authentication device using biometric authentication or an electronic key can be combined and used for power on / off control.

  As a mechanism for the drive shaft to drive the restricting member, a guide groove can be provided on one of the restricting member and the drive shaft, and a guide pin can be provided on the other to be movably fitted in the guide groove. Thus, the guide groove can be appropriately formed such that the guide pin guides and guides the guide groove, the regulating member swings, and the regulating pin locks the connecting member.

  According to the gaming machine locking device of the present invention configured as described above, since the regulating means is driven and the unlocking operation is prohibited by turning on the power switch at all times when the power is supplied, it is high. Security performance can be maintained. Here, when it becomes necessary to open the middle frame, the unlocking prohibition state is canceled by turning off the power switch, and the unlocking operation can be performed by operating the cylinder lock. In the aspect in which the security authentication device is combined, the power supply control by an unspecified person can be prevented and only the operation of a legitimate attendant can be allowed, so that the crime prevention performance is further improved. Further, when the power is not supplied, the unlocking prohibition state is released in the same manner as when the power switch is turned off, so that the unlocking operation can be performed and the operation is not disabled.

  The guide groove of the restricting member includes a swing guide groove provided to be inclined in a moving direction in which the drive shaft protrudes or is sucked, and the drive shaft with the restricting member engaging the connecting member. It is preferable that a locking guide groove portion provided in parallel with the moving direction is formed continuously.

  It is preferable that the guide groove has a groove shape in which the swinging guide groove portion and the locking guide groove portion are connected and refracted in the middle. In addition to driving the regulating member, the unlocking prohibited state is further solidified. Can do. More specifically, when the drive shaft of the electrical release means is attracted by turning on the power, the guide pin and the guide groove are relatively displaced, and the guide pin moves in the swinging guide groove portion that is inclined. At this time, the restricting member guided and guided by the action of the inclined groove is swung in an oblique direction different from the moving direction of the drive shaft. By the swinging, the restriction pin of the restriction member reaches from the released position to the position where it is locked, and the unlocking operation is prohibited. Here, the guide pin moves from the refracting point at the end of the swinging guide groove to the locking guide groove and further advances. Since the groove direction of the locking guide groove and the moving direction of the drive shaft are parallel, the regulating member does not swing, the guide pin reaches the end of the locking guide groove, and the suction of the drive shaft is completed. To do.

  In a state where the guide pin has reached the end of the locking guide groove portion, even if an attempt is made to release the connecting member by applying an external force in the direction of releasing the restricting pin, the restricting member does not swing and an illegal operation cannot be performed. This is because the external force induces a pressing force orthogonal to the groove direction between the guide pin and the locking guide groove, and no force is applied in the direction in which the guide pin comes out of the locking guide groove. On the other hand, in an embodiment in which there is no locking guide groove portion and only the swing guide groove portion, the guide pin and the swing guide groove portion are relatively moved because the guide pin is pressed against the swing guide groove portion by an external force from an oblique direction. The regulating member may swing. Therefore, by holding the guide pin in the locking guide groove, the regulating member is prevented from swinging due to an external force, and the unlocking prohibited state is further solidified.

  A glass frame pivotally supported by the outer frame or the inner frame, and second locking means for mechanically locking the inner frame; and the restricting means performs a unlocking operation of the second locking means. It is preferable to also serve as a second restricting means that is prohibited or permitted.

  When the second locking means for mechanically locking the glass frame and the middle frame is provided, the restricting means can be combined. For example, the second locking means is composed of a locked member and a locking member similar to the locking means, and the common restricting member locks the locking members of the two locking means at once. can do. At this time, the electrical release means is also used, and the two locking means have the same high security performance.

  According to the gaming machine locking device of the present invention described above, since the regulating means is always driven by turning on the power and the unlocking operation is prohibited, high crime prevention performance can be maintained and power is not supplied. Sometimes, the unlocking prohibition state is canceled and the unlocking operation becomes possible, and the operation is not disabled.

  Further, in a mode in which the guide member is provided on one of the restricting member and the drive shaft and the other has a guide groove in which the swing guide groove and the locking guide groove are connected, the restriction member is prevented from swinging due to an external force. The lock prohibition state is further solidified.

It is formed with.

  An electromagnetic solenoid 51 is applied to the slider lock mechanism 5 and is wired so that the power is turned on and off by a power switch (not shown). The drive shaft 52 of the electromagnetic solenoid 51 is provided with a guide pin 53 that protrudes toward the front side in the figure, and the guide pin 53 is movably fitted in the guide groove 43. The root side of the drive shaft 52 has a small diameter, and a compression spring member 54 is provided. The compression spring member 54 urges the drive shaft 52 to protrude upward. When the electromagnetic solenoid 51 is powered off, as shown in FIG. 3B, the drive shaft 52 is biased by the compression spring member 54 and protrudes upward, and the guide pin 53 is a swing guide above the guide groove. Located in the groove 431, the locking lever 4 is driven counterclockwise. When the power of the electromagnetic solenoid 51 is turned on, the drive shaft 52 is attracted downward by the compression spring member 54 and the guide pin 53 swings upward of the guide groove 43 as shown in FIG. It moves downward in the guide groove 431, proceeds to the locking guide groove 432, and finally contacts the lower end of the locking guide groove 432. At this time, the locking lever 4 is driven clockwise, and the restriction pin 42 is driven leftward in the drawing.

  Next, returning to FIG. 2, the relationship between the locking lever 4, the middle frame slider 23 and the glass frame slider 33 will be described. As shown in the figure, the lower end of the glass frame slider 33 is a regulated end 332, and a regulated projection 232 that protrudes rightward in the drawing is provided near the lower portion of the middle frame slider 23. . When the power of the electromagnetic solenoid 51 is turned on, the restriction pin 42 of the locking lever 4 is driven to a position below the restricted end 332 and above the restricted protrusion 232, and both are locked. The lock is prohibited. In other words, the lowering of the glass frame slider 33 and the raising of the middle frame slider 23 are prohibited together by the restriction pin 42.

  Here, when the power is not supplied, and when the staff turns off the power switch with the intention of unlocking, the drive shaft 52 of the electromagnetic solenoid 51 is unsucked and protrudes. Then, the locking lever 4 is swung counterclockwise, the restriction pin 42 is moved in the right direction in the figure, the locking is released, and the unlocking operation is allowed. Therefore, it can be unlocked as shown in FIGS.

Therefore, the glass frame 93 can be opened.

  In the gaming machine locking device 1 of the embodiment, even if an external force F is applied to try to release the restriction pin 42 to the right, the external force F locks the guide pin 53 as shown in FIG. The guide groove 432 is pressed from the side. For this reason, the guide pin 53 does not come out of the locking guide groove 432, the locking lever 4 does not swing, and unauthorized operation cannot be performed. Further, the locking lever 4 and the slider lock mechanism 5 are disposed in the storage case 921, and it is difficult to make contact from the outside. Therefore, the unlocking prohibition state is firmly maintained, and a more reliable crime prevention performance is realized.

  In contrast to the embodiment, the receiving member may be provided on the middle frame 92 and the hook, the connecting member, and the cylinder lock may be provided on the outer frame 91. Further, the same operation and effect can be realized by providing a guide pin on the locking lever 4 and a guide groove on the drive shaft 5.
