Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a locking device for a gaming machine.

  A gaming machine such as a pachinko machine installed in an amusement store generally includes a main body case and a front door pivotally supported by the main body case so as to be opened and closed. A large number of electronic control devices, display devices, and the like are mounted on the front door provided with a game surface, and are often opened and closed frequently in order to cope with problems during game play and to adjust after closing. In order to perform this frequent opening and closing, a structure in which one side portion of the front door is pivotally supported by a main body case to rotate is widely used. However, since the front door has a considerable weight, when the door is opened, it is easy to generate a “door down” state in which the front door is lowered by its own weight. Moreover, although the front door is always locked so that a player cannot open and close it without permission, a case where an inadequate locking is assumed when the attendant closes carelessly is not preferable.

As a countermeasure against this, the applicant of the present application discloses a locking device for gaming machines in Patent Document 1. The locking device of Patent Document 1 includes a drive mechanism, and is configured to assist subsequent locking operations when the front door is closed to an intermediate position by an operator. Thereby, the load applied to the operator is reduced, and the front door is reliably rotated to the complete locking position.
Japanese Patent Laying-Open No. 2005-87692

  By the way, in the locking device of Patent Document 1, the unlocking operation is performed by inserting a key into a key cylinder. Not only Patent Document 1, but also in unlocking the front door, a system is often used in which a key is inserted into the key cylinder from the front door or the front surface of the main body case and rotated. In this method, the key cylinder is exposed and can be easily touched by an unspecified person, so there is a risk of an unauthorized unlocking operation such as a key lock or picking, and it cannot be said that crime prevention is high.

  On the other hand, the locking device of Patent Literature 1 includes, for example, a motor as a driving mechanism for locking. Since this motor can be provided inside the gaming machine so that it cannot be illegally operated from the outside, if it can be applied for unlocking, it is considered possible to improve crime prevention while suppressing an increase in cost.

  Further, a pachinko machine is generally provided with a glass frame that covers the game surface and can be opened and closed. Improvement in crime prevention is also desired for the locking of the glass frame.

  The present invention has been made in view of the above background, and provides a gaming machine capable of locking a front door and a glass frame with high crime prevention performance without using a key cylinder and suppressing an increase in cost.

  The gaming machine of the present invention includes a main body case, a front door pivotally supported by the main body case, a locked member provided on one of the main body case and the front door, and the other A locking member that is provided and engages the locked member in a half-locked position before the front door closes, and engages the locked member in a full-locked position when the front door is closed; A locking member that locks the locking member at the half-lock position and the full-lock position; a locking drive unit that drives the locking member at the half-lock position to the full-lock position; and locking the locking member And an electrically operated lock driving unit to be released.

  The present invention focuses on the improvement of the locking device disclosed in Patent Document 1, and in order to improve the crime prevention performance while maintaining the assist function at the time of locking, the lock is released by an electric operation instead of a key operation by an attendant. ing. The present invention can be applied to a locking device such as a slot machine other than a pachinko machine. Various conventional structures can be applied to the main body case, the front door itself, or the pivot portion.

  The locked member is a member that is fixed to one of the main body case and the front door, and can be formed of, for example, a bar that is fixed horizontally. The locking member is a member provided on the other of the main body case and the front door. For example, the locking member can be formed of a rotating member having a locking groove on the outer peripheral portion. Then, as the front door approaches the main body case, the locked member and the locking member approach each other, the locked member is fitted into the locking groove before the front door is closed, and thereafter the front door is completely closed. The locked member can be disposed so as to push and rotate the locking member. Here, when the locked member is fitted into the locking groove, and the fitting is not released, the rotation position of the locking member is the half-lock position, and the locking member when the front door is completely closed Is the full lock position. Each of the locked member and the locking member may be one or a plurality of sets.

  The lock member is a member that locks the locking member at the half lock position and the full lock position. In the example of the rotating locking member described above, the half lock groove and the full lock groove can be formed on the outer peripheral portion of the locking member. And the protrusion part fitted to a half lock groove | channel and a full lock groove | channel can be provided in a lock member, and it can arrange | position so that it may be biased toward a locking member. Further, when the locking member rotates and reaches the half lock position or the full lock position, the protrusion can be disposed so as to fit into the half lock groove or the full lock groove. And when a projection part fits in either lock groove, rotation of the locking member in the unlocking direction can be prevented. Thus, locking, that is, locking can be performed by fitting the protrusion of the lock member into the lock groove of the locking member.

  The locking drive unit is a part that drives the locking member at the half-lock position to the full-lock position. The locking drive unit can be formed by a drive source such as a motor that generates a driving force, and a locking drive mechanism that appropriately converts and transmits the driving force. The fact that the locking member is in the half-lock position may be detected by providing a separate sensor, or a mechanical mechanism that automatically starts driving at a predetermined position may be provided. The fact that the locking drive unit drives the locking member to the full lock position means that the front door is driven to be completely closed, and has a so-called “closer” role. That is, the locking drive unit operates while the clerk closes the front door to assist in reducing the labor of the clerk and to reliably drive to the complete locking position.

  The lock driving unit is a part that unlocks the lock member by an electric operation. In the example of the lock member that has the above-described protrusion and is urged toward the locking member, the lock driving unit can release the lock by driving the lock member in a direction in which the lock member is pulled away from the engagement member. This is because the protruding portion comes out of the lock groove that has been fitted, and the locking member is allowed to rotate in the unlocking direction. The lock drive unit can be formed by an electric drive source that generates a drive force and a lock drive mechanism that appropriately converts and transmits the drive force.

  It is preferable that a part of the lock driving unit is also used as the locking driving unit. That is, it is preferable that the electric drive source of the lock drive unit and a part of the drive mechanism are also used as the locking drive unit. For example, two cams can be provided on the output shaft of the electric drive source of the lock drive unit, and the lock drive mechanism and the lock drive mechanism can be driven at different rotational phases. If necessary, it is also possible to obtain a desired driving torque and driving speed by using a reduction mechanism or the like. As described above, by sharing a part of the lock driving unit, it is possible to simplify the configuration of the gaming machine, suppress the increase in cost, and save the space for component arrangement.

  Next, an electronic authentication unit for further improving crime prevention will be described. It is preferable to provide an electronic authentication unit that allows operation of the lock driving unit only when a predetermined electronic authentication condition is satisfied.

  Unlocking operation can be performed by connecting a power source to an electrically operated lock driving unit. However, since an unspecified player can touch only by providing a normal switch, there is a problem in terms of crime prevention. Therefore, it is preferable to incorporate an electronic authentication unit that is difficult to perform an unauthorized operation by a key combination or picking. The electronic authentication unit can be inserted in series with the switch in the middle of the power line of the lock driving unit, for example. And it can be configured to conduct only when predetermined electronic authentication conditions are satisfied.

  As a method of electronic authentication, known methods such as magnetic information, a password code, and biometric information can be applied. For example, the authentication condition can be that an electronic key or IC card in which specific magnetic information is recorded is inserted into an acceptor provided on the front surface of the gaming machine. Alternatively, a receiver may be provided in each gaming machine, and the unlocking command may be transmitted wirelessly using a unique code for each gaming machine. Furthermore, a biometric information reading device such as a fingerprint or a voiceprint may be provided to distinguish only registered staff.

  Next, the glass frame locking device will be described. A glass frame pivotally supported by the main body case or the front door; a frame locking portion that locks the glass frame; and an electrically operated frame lock driving portion that unlocks the frame locking portion. The electronic authentication unit may allow the operation of the frame lock driving unit.

  Even a frame locking portion of a glass frame that does not require an assist function can be configured to include an electrically operated frame lock driving portion and an electronic authentication portion. Here, the power source and the electronic authentication unit can be shared by the front door and the glass frame so that the unlocking operation can be performed when the electronic authentication condition is satisfied. According to this aspect, the crime prevention property of the locking device for the glass frame can be enhanced, and the gaming machine can be simply configured to suppress an increase in cost.

  In the gaming machine according to the present invention, since the lock driving unit for electric operation is provided in order to unlock the lock member that locks the front door, it is possible to prevent an unauthorized operation by a conventional key combination or picking. Furthermore, in an aspect provided with an electronic authentication unit, operations other than the staff are difficult, and the crime prevention performance is further improved. In addition, the electronic authentication unit can be shared with the frame locking part of the glass frame, and the crime prevention performance can be further improved and the increase in cost can be suppressed.

  The best mode for carrying out the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating a general structure of the gaming machine 9. The gaming machine 9 is mainly composed of a substantially rectangular frame-shaped main body case 1, a front door 2 provided with a game surface, a game handle, and the like, and a glass frame 3 that always covers the front door 2. ing. The front door 2 and the glass frame 3 are pivotally supported by a pivotal support portion 91 provided on the left end front surface of the main body case 1 so as to be opened and closed. That is, the front door 2 opens and closes with respect to the main body case 1 by rotating about the left side in the figure as an axis. Further, the glass frame 3 is configured to open and close with respect to the front door 2 by rotating about one side portion on the back side in the figure as an axis. Here, since the front door 2 and the glass frame 3 open and close independently, it is necessary to lock them separately. Various members for locking are arranged on the right side of the gaming machine 9.

  FIG. 2 is a diagram for explaining the gaming machine according to the embodiment of the present invention, and is a main part viewed from the right side X direction of the gaming machine 9 shown in FIG. FIG. 2 shows a state in which both the front door 2 and the glass frame 3 are locked, and unnecessary members are omitted for easy viewing. In the gaming machine of the present invention, as a locking device for the front door 2. Two sets of locked members and locking members, a lock member 5, and a common drive unit 6 that also serves as a lock drive unit and a lock drive unit are provided. Further, as a locking device for the glass frame 3, two sets of locked members and locking members, and a frame lock driving unit 7 are provided. Further, an electronic authentication unit that is not shown in FIG. 2 is provided as a part that allows the common drive unit 6 and the frame lock drive unit 7 to be operated.

  First, the locking device for the front door 2 will be described. The locked member for the front door 2 is formed by horizontally fixing a bar on the right front surface of the main body case, the lower locked member 11 on the lower side, and the upper locked member 12 on the upper side. The locking members are respectively provided at locations facing the locked member on the front door 2 side, the lower locking member 41 on the lower side and the upper locking member 42 on the upper side. As shown in FIG. 2, the upper locking member 42 has a center 421 pivotally supported, and one end thereof is bent upward to form a return portion 422. The return portion 422 is biased upward by a spring 423 so as to lock the upper locked member 12 in a state where the front door 2 is closed. A connecting hole 424 is provided at the other end of the upper locking member 42, and an upper connecting member 67 described later is coupled thereto.

  The lower locking member 41 is a plate-like member that is locked by the lock member 5 while locking the lower locked member 11. FIG. 3 is a partially enlarged perspective view illustrating the lower locking member 41, the lock member 5, and the common drive unit 6. As shown in FIG. 3, the lower latch member 41 is formed so as to pivot around a center 411 and have a latch groove 412 on the upper side of the outer peripheral portion. The locking groove 412 has a width and depth sufficient to hold the lower locked member 11 and is locked by rotating counterclockwise in the drawing. Further, two lock grooves into which the lock member 5 is fitted are formed in the upper left portion of the outer peripheral portion of the lower locking member 41. The left side in the drawing is the half lock groove 413, and the right side is the full lock groove 414. . Further, a driven projection 415 driven by a locking cam 63 described later is formed below the outer peripheral portion of the lower locking member 41.

  The lock member 5 is a plate-like member disposed above the lower locking member 41, and is formed so that the right end 511 is pivotally supported to swing. A protrusion 512 that protrudes toward the lower locking member 41 is formed on the lower side of the lock member 5. The lock member 5 and the lower locking member 41 are biased by a spring 52 so as to press each other. By this spring 52, the projection 512 is biased toward the lower locking member 41 and is fitted into the half lock groove 413 and the full lock groove 414. Here, the rotation position of the lower locking member 41 when the projection 512 is fitted into the half lock groove 413 is the half lock position, and the locking member when the projection 512 is fitted into the full lock groove 414. The rotation position 41 is the full lock position.

  The protrusion 512, the half lock groove 413 and the full lock groove 414 are formed asymmetrically and have a ratchet function. That is, when the spring 52 is biased, the lower locking member 41 can be rotated counterclockwise, but clockwise rotation is prevented. Therefore, the protrusion 512 can be fitted and operated only in the locking direction from the non-fitting position to the half lock groove 413 and from the half lock groove 413 to the full lock groove 414.

  Next, the common drive unit 6 that drives the lower locking member 41 and the lock member 5 in common will be described with reference to FIGS. 3 and 4. As shown in FIG. 4, the common drive unit 6 includes a common drive motor 61 as a drive source. A worm gear 621 is provided on the output shaft of the common drive motor 61, and a small gear 623 that rotates together with the helical gear 622 that meshes with the worm gear 621 is provided. Further, the large gear 624 that meshes with the small gear 623 is provided with a locking cam 63 that rotates together on the front side of the paper and an unlocking cam 64 on the back side of the paper. The output rotation speed is appropriately reduced by a drive mechanism in which these gears 621, 622, 623, and 624 are combined. In addition, the power line of the common drive motor 61 can be connected in reverse, and the rotation direction can be switched.

  Returning to FIG. 3, the locking cam 63 rotates in the clockwise direction so as to contact and drive the driven protrusion 415 and rotate the lower locking member 41 counterclockwise. Yes. Further, a stopper 631 is provided for stopping the counterclockwise rotation of the locking cam 63 halfway. Furthermore, the common drive unit 6 includes a sensor (not shown) that detects the half-lock position of the lower locking member 41, and automatically operates the common drive motor 61 when the half-lock position is detected. .

  In FIG. 3, the unlocking lever 65 is swingable with the center 651 pivoted, and is engaged with an unlocking cam 64 not shown on the right side in the drawing. A lower connecting member 66 and an upper connecting member 67 are coupled to the left side of the unlocking lever 65 in the drawing, and are urged by a spring 652 so that the left side is always lowered. The lower connecting member 66 is coupled to the left end 513 of the lock member 5 at the upper side. The upper connecting member 67 is coupled to the connecting hole 424 of the upper locking member 42 at the upper side. When the unlocking cam 64 rotates counterclockwise, the unlocking lever 65 is lowered on the right side and raised on the left side. By this operation, the lock member 5 and the upper locking member 42 are driven.

  Next, the operation and action of the locking device for the front door 2 configured as described above will be described with reference to FIGS. FIGS. 5A and 5B are diagrams for explaining the locking operation of the front door 2. FIG. 5A shows an unlocked state, FIG. 5B shows a half-locked state, and FIG. 5C shows a full-locked state. 5A, the front door 2 is unlocked and opened, and the lower latch member 11 and the lower latch member 41 are separated from each other. At this time, the lower locking member 41 is rotated to the full clockwise direction, and the locking groove 412 is opened to the upper right so that the lower locked member 11 can be fitted. Further, the protrusion 512 of the lock member 5 is located on the left side of the half lock groove 413 of the lower locking member 41.

  When the clerk turns the front door 2 from the unlocked state of FIG. 5A and approaches the main body case, the lower locking member 41 becomes the lower locked member as indicated by the arrow Y in the figure. 11 is approached. Then, as shown in FIG. 5B, the lower locking member 11 is fitted into the locking groove 412, and the lower locking member 41 starts to rotate counterclockwise. Then, the half lock groove 413 is also rotated, and the protrusion 512 is fitted.

  When the clerk performs the operation vigorously, the front door 2 is completely closed at a stretch due to inertia, and the lower locking member 41 rotates counterclockwise as shown in FIG. 512 slides from the half lock groove 413 and fits into the full lock groove 414. In the case where the clerk's operation is slow or the frictional resistance is generated by “door down”, the speed of stopping or closing in the half lock state of (B) is lowered. At this time, a sensor (not shown) detects the half-lock position of the lower locking member 41 and operates the common drive motor 61. Then, the locking mechanism 63 is driven clockwise by the driving mechanism shown in FIG. 4 to push the driven projection 415, and the lower locking member 41 is fully rotated counterclockwise. The operation is assisted to the state.

  During the closing operation and in the closed state, a ratchet function is working between the protrusion 51 and the lock grooves 413 and 414. Therefore, the clockwise rotation of the lower locking member 41 is prevented, and finally the front door 2 is locked in the full lock state (C) in which the protrusion 512 is fitted in the full lock groove 414.

  In the upper locking member 42 shown in FIG. 2, the upper locked member 12 is locked in synchronism with the lower locking member 41 side. That is, when the clerk approaches the front door 2 to the main body case, the upper locking member 42 approaches the separated upper locked member 12. Subsequently, the upper locked member 12 pushes down the return portion 422 of the upper locking member 42 against the spring 423 and gets over the return portion 422. Then, once the upper latched member 12 gets over, it is locked as shown in FIG. 2 by the action of the spring 423 and the return portion 422.

  Next, the unlocking operation of the front door 2 will be described with reference to FIG. 6A and 6B are diagrams for explaining the unlocking operation of the front door 2, wherein FIG. 6A shows a full lock state and FIG. 6B shows an unlock state. In the full lock state of FIG. 6A, the lock member 5 is pressed against the lower locking member 41 that locks the lower locked member 11 by the bias of the spring 52. By this pressing, the protrusion 512 of the lock member 5 is fitted in the full lock groove 414 of the lower locking member 41. Further, the unlocking lever 65 is biased by the spring 652, and the left side is lowered.

  Here, when the unlocking instruction is issued by the staff, the power line of the common drive motor 61 is reversely connected to operate, and the locking cam 63 and the unlocking cam 64 are driven counterclockwise. The locking cam 63 rotates until it comes into contact with the stopper 631 as shown in (B), and is separated from the driven protrusion 415. Further, when the unlocking cam 64 rotates, it engages with the right side 653 of the unlocking lever 65 and pushes down the right side 653 against the spring 652, so that the left side rises. Therefore, the lower connecting member 66 and the upper connecting member 67 coupled to the left side of the unlocking lever 65 are raised. Further, when the left end 513 of the lock member 5 is driven upward by the lower connecting member 66, the protrusion 512 is also driven upward to come out of the full lock groove 414, and the unlocked state shown in FIG. It becomes. If the front door 2 is opened in this state, the lower locking member 41 rotates clockwise, the locking groove 412 opens to the upper right, and the lower locked member 11 comes out in the direction of arrow Z in the figure. it can.

  When the other end of the upper locking member 42 is driven upward by the upper connecting member 67, the return portion 422 on one end side is driven downward against the spring 423. Thereby, the upper locked member 12 is unlocked. Eventually, the lower latch member 11 and the upper latch member are unlocked together and unlocked, and the front door 2 can be opened.

  As described above, since the locking device of the front door 2 of the embodiment does not have a key cylinder, unauthorized unlocking by a key lock or picking cannot be performed, and the crime prevention performance is high.

  Next, the locking device for the glass frame 3 will be described. As shown in FIG. 2, the locked member for the glass frame 3 is formed by horizontally fixing a bar on the right rear surface of the glass frame 3, the lower side is the lower locked member 35, and the upper side is This is an upper locked member 36. The locking members are respectively provided at locations facing the locked member on the front door 2 side, and the lower side is the lower locking member 45 and the upper side is the upper locking member 46. As shown in the figure, the lower locking member 45 and the upper locking member 46 are pivotally supported at the centers 451 and 461. Return portions 452 and 462 bent downward are formed at one end of the lower locking member 45 and the upper locking member 46, and are urged downward by a spring (shown as only the lower side 459 in FIG. 3). . Long holes 453 and 463 that are long in the vertical direction are formed in the other ends of the lower locking member 45 and the upper locking member 46. Further, the two elongated holes 453 and 463 are connected by a connecting member 47. Near the center of the connecting member 47, a frame lock driving unit 7 shown in FIG.

  FIG. 7 is a perspective view of the frame lock driving unit 7 for releasing the lock of the locking device of the glass frame 3. The frame lock drive unit 7 includes a frame drive motor 71 as a drive source. A worm gear 721 is provided on the output shaft of the frame drive motor 71, and a drive protrusion 73 is provided on a side surface of the helical gear 722 that meshes with the worm gear 721. Further, the frame operating lever 74 is swingable with the center 741 pivoted, and the left end 742 in the drawing is coupled to the connecting member 47. A driven groove 743 is formed on the right side of the frame operation lever 74 in the figure so that the drive protrusion 73 is engaged. Further, a recessed fitting seat 744 into which the driving protrusion 73 is fitted is formed on the right side of the entrance of the driven groove 743.

  Next, the operation and action of the locking device for the glass frame 3 configured as described above will be described with reference to FIGS. Note that the upper and lower two frame locking portions have substantially the same operation and action, and therefore the upper side will be described as a representative. When the clerk turns the glass frame 3 and approaches the front door 2, the upper locked member 36 approaches the separated upper locking member 46. Subsequently, the upper locked member 36 pushes the return portion 462 of the upper locking member 46 upward and passes through the return portion 462. At this time, the other end of the upper locking member 46 is coupled to the connecting member 47 through the elongated hole 463 and has play, so that the connecting member 47 is not obstructed. The upper locked member 36 once passed is locked by the return portion 462 as shown in FIG.

  FIG. 8 is a diagram for explaining the unlocking operation of the glass frame 3, in which (A) shows a locked state and (B) shows an unlocked state. In the locked state of FIG. 8A, the frame operation lever 74 is lowered on the right side in the drawing, and the drive protrusion 73 is fitted in the fitting seat 744. In this state, when an unlocking instruction is issued by the clerk, the frame drive motor 71 operates to drive the helical gear 722 clockwise. Then, the drive protrusion 73 drives the frame operation lever 74 counterclockwise while coming out of the fitting seat 744 and engaging with the driven groove 743. As a result, the left end 742 of the frame operation lever 74 is lowered, the connecting member 47 is also lowered, and the long hole 463 at the other end of the upper locking member 46 is pulled down. Then, the return portion 462 at one end of the upper locking member 46 rises, and the upper locked member 36 is unlocked. Similarly, the lower cover locking member 35 is also unlocked, and the glass frame 3 is unlocked.

  In the locking device for the glass frame 3, even if one of the lower locking member 45 and the upper locking member 46 is picked from the gap between the glass frame 3 and the front door 2, the connecting member is caused by the play of the long holes 453 and 463. 47 does not move. Therefore, both the upper and lower locks are not released at the same time and are not unlocked. Further, the picking of the connecting member 47 is prevented by the frame operation lever 74 as shown in FIG. More specifically, in order to lower the connecting member 47 in the locked state, it is necessary to swing the frame operation lever 74 counterclockwise and lower the left end 742. However, even if the left end 742 is lowered, the fitting seat 744 on the right side of the frame operation lever 74 presses the drive protrusion 73 only in the axial direction of the helical gear 722. Therefore, the drive protrusion 73 does not come off to the left or right of the fitting seat 744, and the frame operation lever 74 does not swing and is not unlocked.

  As described above, the locking device for the glass frame 3 of the embodiment also has high crime prevention performance.

  Next, an electronic authentication unit for further improving crime prevention will be described with reference to FIG. FIG. 9 is a connection conceptual diagram in which the electronic authentication unit 8 is incorporated in the electrical connection of the gaming machine of the embodiment. As shown in FIG. 9, in the electrical connection method of the embodiment, the connection line from the power source 93 to the in-flight electrical component 92 is branched and connected to the input side 811 of the electronic control unit 81. The electronic control unit 81 is provided with a front door switch 85 and a frame switch 86. The output side 812 of the electronic control unit 81 is connected to the input side 801 of the electronic authentication unit 8. A common drive motor 61 and a frame drive motor 71 are connected in parallel to the output side 802 of the electronic authentication unit 8. The electronic authentication unit 8, the front door switch 85, and the frame switch 86 are provided on the front surface of the gaming machine.

  The electronic authentication unit 8 is configured such that the input side 801 and the output side 802 are electrically connected only when a predetermined electronic authentication condition is satisfied. Various known methods can be applied to the electronic authentication unit 8 and there are no restrictions. Further, in the electronic authentication unit 8, only the common drive motor 61 is turned on when the front door switch 85 is operated, and only the frame drive motor 71 is turned on when the frame switch 86 is operated. ing. The electronic control unit 81 performs control so as to cut off this conduction after a certain time after unlocking.

  According to the electrical connection incorporating the electronic authentication unit 8 as described above, the clerk satisfies the predetermined electronic authentication condition at the electronic authentication unit 8 and selectively operates the front door switch 85 or the frame switch 86. By doing so, the front door 2 or the glass frame 3 can be unlocked. Further, when the front door 2 is closed, the operation is assisted by the common drive motor 61.

  On the other hand, even if the player can operate the front door switch 85 and the frame switch 86, the player cannot satisfy the electronic authentication condition of the electronic authentication unit 8. Accordingly, the crime prevention performance is further improved.

It is a figure explaining the general structure of a gaming machine. It is a figure explaining the principal part of the locking device of a front door in the game machine of the Example of this invention.
