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. In addition, the unlocking operation of the clerk becomes complicated due to the complexity of the locking device, and there is a risk that the player's comfort may be impaired.

  The present invention has been made in view of the above background, and has a high crime prevention performance at all times, can be unlocked without power being supplied to the gaming machine, and is easy and speedy for unlocking by an attendant. A locking device is provided.

  A locking device for a gaming machine according to the present invention comprises a locking means for mechanically locking an outer frame of a gaming machine and an inner frame pivotally supported by the outer frame, and an unlocking operation of the locking means. Restricting means that is mechanically prohibited or allowed, electrical release means that electrically releases the prohibited state in which the unlocking operation of the locking means is prohibited by the restricting means, and the prohibited state by the restricting means is mechanically And mechanical release means for releasing.

  The present invention includes mechanical restriction means for controlling the unlocking operation of a mechanical locking means such as a cylinder lock, and the release of the unlocking prohibition state of the restriction means is controlled by an electrical release means or a mechanical release means. It is characterized by being able to do either. Therefore, high crime prevention performance can be maintained by always prohibiting the unlocking operation by the restricting means. In the unlocking operation, the unlocking prohibition state of the regulating means can be released by the electrical releasing means or the mechanical releasing means, and even if the power is not supplied, the mechanical releasing means Cancellation is possible.

  The locking means includes a locked member provided on one of the outer frame and the middle frame, a locking member provided on the other side for locking or releasing the locked member, and mechanical A cylinder lock that drives the locking member by operation, and the restricting means prohibits or allows the unlocking operation of the cylinder lock to disengage the locking member and the locked member. It is preferable to have a member.

  A conventional structure can be applied to the locking means itself, and includes a locked member called “receiver”, a locking member called “hook” for engaging and disengaging the locked member, and a locking member. The cylinder lock to drive can be comprised as a main member. For example, the cylinder lock can be disposed on the front surface of the middle frame so that the staff can easily operate it using a key. Between the hook and the cylinder lock, various connecting members that transmit the operating force can be used in appropriate combination. Further, the hook and the connecting member may be integrally formed as a locking member.

  The restricting member prohibits or permits the unlocking operation of the cylinder lock that engages and disengages the locking member and the locked member, and is formed of a mechanical member. The restricting member can be configured, for example, as a restricting pin so as to be fitted into the restricting groove of the engaging member, inserted into the restricting hole, or abutted against the engaging member to engage the engaging member. When the restricting member locks the locking member, the unlocking operation of the cylinder lock cannot be performed, and when the locking is released, the unlocking operation of the cylinder lock can be performed.

  As means for releasing the unlocking prohibited state by the restricting member, electrical release means and mechanical release means can be provided. Both of them can be configured so that one of them can perform the release function and does not interfere with the other. Alternatively, the electrical release means may be prioritized and the mechanical release means may be made effective only when power is not supplied.

  The electrical release means includes a motor or a solenoid that drives the restricting member so that the locking member and the locked member can be engaged and disengaged, and a security authentication device that controls a power source of the motor or the solenoid. It is preferable to have.

  As the electrical release means, for example, a gear mechanism can be provided on the output shaft using a motor, and the restricting member can be driven by the output torque. Alternatively, the regulating member may be driven by displacement of the output shaft by energization using a solenoid, and an urging means such as a spring member may be provided in order to define a non-energized state. The power on / off control of the motor and solenoid can be controlled by a normal switch, but it is preferable to use a security authentication device using biometric authentication or an electronic key. In the security authentication device, the device main body can be provided inside the gaming machine, and the authentication terminal can be provided on the front surface of the middle frame. For example, the clerk can control the power supply by a simple operation of simply touching the fingertip on the fingerprint authentication terminal, but cannot control the power supply even if an unspecified person touches it. Accordingly, the crime prevention performance is further improved by providing a double crime prevention function together with the key of the cylinder lock. In addition, when a malfunction occurs in the gaming machine, the clerk's unlocking operation is easy and speedy, and the player can play comfortably.

  The mechanical release means includes a mechanism unit that drives the restricting member to allow the locking member and the locked member to be engaged and disengaged, and a sub-cylinder lock that drives the mechanism unit by mechanical operation. It is preferable to have.

  As the mechanical release means, a mechanism portion and a sub-cylinder lock are provided. For example, the restriction member can be driven by mechanical operation using a key different from the cylinder lock of the lock means. For example, the sub-cylinder lock is disposed on the front surface of the middle frame, and a mechanical operation force can be transmitted to the regulating member by appropriately configuring a mechanism portion using a connecting member or the like.

  A cover member that covers the sub-cylinder lock may be provided.

  The cover member may have a structure that cannot be easily opened, for example, as a screw. Alternatively, an electrically closed structure can be opened and operated only when power is not supplied. By providing the cover member, the sub-cylinder lock cannot be operated immediately, the mechanical release means is used as an emergency, and the electrical release means is used as a usual release means. As a result, the usual crime prevention performance is improved, and the crime prevention performance is remarkably improved in a mode in which the above-described security authentication device is combined.

  A glass frame pivotally supported by the outer frame or the inner frame so as to be openable and closable; and a second locking means for mechanically locking the inner frame; and the regulating means is an unlocking operation of the second locking means. It is preferable to also serve as a second restricting means for mechanically prohibiting or permitting the above.

  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 and the mechanical release means are 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, it is possible to maintain high crime prevention performance by prohibiting the unlocking operation by the regulating means at all times, and even in a situation where power is not supplied. The unlocking operation can be performed by canceling the unlocking prohibition state of the restricting means by the automatic releasing means.

  Furthermore, in a mode in which the sub-cylinder lock that is a mechanical release means is covered with a cover member and the security release device is included in the electrical release means, the unlocking prohibition state is not released even if an unspecified person touches it. With the double crime prevention function, the crime prevention performance can be remarkably improved, and the unlocking operation by the attendant is easy and speedy.

On the other hand, a cylinder lock 24 is provided near the front lower side of the mounting plate 929, and the lever 241 swings up and down by the turning operation of the staff. When the lever 241 swings upward, the operation claw 231 of the middle frame slider 23 is pushed upward, and the locking claw 212 is lowered and unlocked.

  A locking means 25 for locking or releasing the striker 911 provided on the outer frame 91 is provided below the middle frame 92. The locking means 25 operates in conjunction with the inner frame slider 23 and has the same locking function as that above, although the structure is different.

  The glass frame locking means 3 includes two glass frame receiving members (not shown) provided on the upper side and the lower side of the glass frame 93 and a glass frame receiving member pivotally supported by a mounting plate 929. It is configured to be locked by two glass frame hooks 31 to be stopped and released. The center of the glass frame hook 31 is a pivot portion 311 pivotally supported by the mounting plate 929, a locking claw 312 is formed at one end toward the glass frame 93, and a link portion 313 is formed at the other end. . The locking claw 312 is configured to lock the glass frame receiving member by lowering, and to release the glass frame receiving member by moving up. A glass frame link rod 32 extending downward is connected to the link portion 313 of the upper glass frame hook 31. A glass frame slider 33 is further connected to the lower end of the glass frame link bar 32. The link portion of the lower glass frame hook 31 is directly connected to the glass frame slider 33. When the lever 241 of the dual-purpose cylinder lock 24 swings downward, the operation claw 331 of the glass frame slider 33 is pushed down, and the locking claw 312 is raised and unlocked. .

  Next, the structure of the locking lever 4 and the motor 5 will be described with reference to FIGS. Drawing 3 is a figure explaining the principal part of the lower part of locking device 1 of an example, (A) is a right view, and (B) is a back view. The locking lever 4 is hatched in the figure for easy viewing. As shown in FIG. 3A, the locking lever 4 and the motor 5 are disposed in a storage case 921 fixed to a mounting plate 929. In addition, on the front side of the storage case 921 in the figure, lower portions of the middle frame slider 23 and the glass frame slider 33 are extended. Further, a release slider 62 of a mechanical release means 6 (described later) extends from the back side of the storage case 921 in the drawing. 4A and 4B are diagrams supplementing the right side view of FIG. 3, in which FIG. 4A shows the structure of the locking lever 4 and the motor 5, and FIG. 4B shows the structure of the locking lever 4 and the release slider 62, respectively. Yes.

  As shown in FIG. 4A, the locking lever 4 is disposed in the storage case 921, and is provided with a pivotal support 401, a regulation pin 402, a release pin 403, and a helical gear 404 on a plate-like member. Has been formed. The pivotal support 401 is pivotally supported by the storage case 921, and the locking lever 4 can swing. The restriction pin 402 is provided so as to protrude toward the front side of the sheet, and protrudes from the guide window 922 of the storage case 921 as shown in FIG. On the other hand, the release pin 403 protrudes toward the back side of the paper surface and protrudes from the guide window of the storage case 921. The helical gear 404 is formed on the right side of the drawing.

  The motor 5 is an electrical release means. As shown in FIG. 4A, a worm gear 502 is formed on the output shaft 501 and meshes with the helical gear 404 of the locking lever 4. Therefore, by driving the motor 5 in both the forward and reverse directions, the driving force is transmitted from the worm gear 502 to the helical gear 404, and the locking lever 4 is swung in both the clockwise and counterclockwise directions. Can be made. Conversely, power transmission from the helical gear 404 side to the worm gear 502 side is also possible, so that the operation by the mechanical release means 6 described later is not hindered.

  Next, the mechanical release means 6 will be described. As shown in FIG. 2, the mechanical release means 6 includes a sub-cylinder lock 61 and a release slider 62 that transmits a mechanical operating force to the locking lever 4. The sub-cylinder lock 61 is disposed on the front upper portion of the middle frame 92 and is operated with a key different from the cylinder lock 24 that unlocks the two locking means 2 and 3. A release slider 62 extending downward is connected to the lever 611 of the sub cylinder lock 61. As shown in FIG. 3B, the release slider 62 is bent twice downward and reaches the side of the storage case 921 (the back surface in the drawing). Further, as shown in FIG. 4B, a release hole 621 is formed at the lower end of the release slider 62, and the release pin 403 of the locking lever 4 is fitted therein. Therefore, when the sub cylinder lock 61 is rotated, the release slider 62 is pulled up by the operating force, the release pin 403 is lifted, and the locking lever 4 swings counterclockwise. Note that the release hole 621 is formed larger than the release pin 403 and has play in size, so that the release operation by the motor 5 is not hindered.

  Next, a state where the unlocking operation by the locking lever 4 is prohibited will be described with reference to FIG. 5A and 5B are diagrams in which members in the right side view of FIG. 3 are partially omitted. FIG. 5A shows the unlocking state of the middle frame 92, and FIG. 5B shows the unlocking state of the glass frame 93. Show. As shown in FIG. 5, when the locking lever 4 swings clockwise, the restriction pin 402 moves to the left of the guide window 922 of the storage case 921. Then, as shown in (A), the restriction pin 402 locks the regulated protrusion 232 of the middle frame slider 23 to inhibit the middle frame slider 23 from rising. Accordingly, the lever 241 of the cylinder lock 24 is swung upward to push the operating claw 231 upward, and the unlocking operation of the middle frame 92 is prohibited. Similarly, as shown in (B), since the regulating pin 402 locks the regulated end portion 332 of the glass frame slider 33, the lever 241 of the cylinder lock 24 is swung downward to move the operating claw 331 downward. The operation of pushing down the glass frame 93 becomes impossible, and the unlocking operation of the glass frame 93 is prohibited. The restriction pin 402 is a restriction member that serves as both the medium frame restriction means and the glass frame restriction means.

  Next, a method for releasing the restriction pin 402 for allowing the unlocking operation will be described. When the motor 5 is driven or the sub-cylinder lock 61 is rotated, the locking lever 4 swings counterclockwise, and the restriction pin 402 moves to the right of the guide window 922. Then, the locking of the middle frame slider 23 and the glass frame slider 33 is released, and the unlocking prohibited state of the cylinder lock 24 is released.

  Next, the control unit 7 will be described with reference to FIG. FIG. 6 is a diagram for explaining the configuration and connection method of the control unit 7, and broken lines indicate the flow of information. The control unit 7 includes an authentication terminal 71, a security authentication device 72, a middle frame switch 73, a glass frame switch 74, and a control main body unit 75. The authentication terminal 71 is provided on the front surface of the middle frame 92, and reads authentication information such as an inputted fingerprint or an electronic key and transmits it to the security authentication device 72. The security authentication device 72 compares and verifies the transmitted authentication information with preset personal information, and notifies the control main body 75 of the verification result. Note that the personal information set in advance is information on a proper clerk who performs the unlocking operation. The middle frame switch 73 and the glass frame switch 74 detect the open / closed states of the middle frame 92 and the glass frame 93, respectively, and notify the control main body 75. The control main body 75 determines whether or not unlocking is possible based on the notified collation result, and permits or prohibits unlocking, and further prohibits unlocking after the frames 92 and 93 are closed. 5 is controlled. For the control main body 75, an electronic control device using a microcomputer is used.

  Next, an operation method and operation of the gaming machine locking device 1 according to the embodiment will be described with reference to FIG. FIG. 7 is a diagram for explaining the opening / closing operation flow of the glass frame 93, and the numbers in parentheses correspond to the descriptions in the following description. In addition, since the opening / closing operation flow of the middle frame 92 is the same, the description is omitted.

  In order to open the glass frame 93 of the gaming machine 9, the attendant first inputs authentication information to the authentication terminal 71 (1). For example, the fingerprint information is read by touching the authentication terminal 71 with a fingertip. Alternatively, an electronic key is inserted to read electronic information. Then, the security authentication device 72 compares and verifies the read authentication information with the set personal information (2). If the collation result is valid (3), the control main body 75 drives the motor 5 to release the restriction pin 402 and release the unlocking prohibition state (4). If the collation result is invalid (3), it waits for the input of authentication information again. When the unlocking operation is permitted, the clerk can rotate the cylinder lock 24, the hook 31 releases the receiving member to unlock (5), and the glass frame 93 can be opened (6). . When the work is finished and the clerk closes the glass frame 93, the hook 31 locks the receiving member and is locked (7). Then, the glass frame switch 74 detects the closed state of the glass frame 93 and notifies the control main body 75 (8). The control main body 75 drives the motor 5 to drive the regulation pin 402, and locks the glass frame slider 33 to prohibit the unlocking operation (9).

  As described in the above-described opening / closing operation flow, in this embodiment, the electrical release means is usually used with priority. However, when power is not supplied, the operations (2) to (4) are not performed. At this time, by rotating the sub cylinder lock 61, the restriction pin 402 is released and the cylinder lock 24 can be operated.

  Further, even if an unspecified person inputs authentication information, since it is determined to be invalid in (3), (4) is not reached. Therefore, even if an attempt is made to move the glass frame slider 33 with a matching key or an unauthorized operation, the restriction pin 402 prohibits the movement, so that it is not unlocked. In other words, the high crime prevention performance can be maintained by the double crime prevention function.

  In addition, as shown in FIG. 8, a cover member 65 that covers the sub cylinder lock 61 may be provided. The cover member 65 is provided on the front surface of the sub-cylinder lock 61 and is screwed to the middle frame 92. Accordingly, the rotation operation from the front surface of the sub-cylinder lock 61 cannot be performed at all times, and the mechanical release means 6 is used as an emergency.

  In contrast to the embodiment, the receiving member may be provided on the middle frame 92 and the hook, the link bar, the slider, and the cylinder lock may be provided on the outer frame 91. Furthermore, an assist device that assists the closing operation of the middle frame 92 with respect to the outer frame 91 or the closing operation of the glass frame 93 with respect to the middle frame 92 may be provided as appropriate.
