[0001]
[Industrial application fields]
The present invention stores a control board of a so-called computer-controlled gaming machine such as a pachinko gaming machine or a pachislot gaming machine, and a sealing mechanism for a gaming machine board box or a gaming board box as a gaming machine frame. This is related to the sealing mechanism of the fixing mechanism to be fixed, and the number of times the board box is released or removed must be clearly specified, and by managing this specified number of times of release (or removal, the same shall apply hereinafter) It is possible to confirm the presence / absence of release, thereby making it easy to properly perform a normal release operation and resealing operation of the substrate box, and to make it clear at a glance whether there is any unauthorized release.
[0002]
[Prior art]
Since individual characteristics of the computer-controlled gaming machine are greatly influenced by control information (control program, control data, etc.) stored in the control board, it is necessary to strictly control access to the control board. On the other hand, since a regular access is made to the control board of the gaming machine for periodic inspections, it cannot be made unreleasable. For this reason, the substrate box is made releasable and sealed every time it is released, so that it can be quickly confirmed when released without permission. For this sealing, the simplest method is a method of sealing with a so-called sealing seal, and a number of irreversible locking mechanisms are prepared, each of which is used every time the board box is locked and released. A method is adopted in which the lock mechanism is destroyed one by one, and the trace of being released is left by the destruction.
In the case of sealing with a so-called seal, it may not be easy to confirm unauthorized release, such as using a counterfeit seal, and as a safety measure, there are aspects that are difficult to ensure, and an irreversible lock When using a mechanism, there is an inconvenience that when the release is properly performed, the release operation and the reseal operation are relatively troublesome and it is necessary to use a special tool. On the other hand, the board box of the gaming machine is designed on the assumption that regular release for inspection or the like is performed at least several times, so that at least several irreversible locks are required. For this reason, an irreversible locking mechanism is attached to the substrate box, so there is no problem that the manufacturing cost of the substrate box is increased.
[0003]
In addition to sealing by seal and irreversible locking mechanism, a board box is provided with a lock, and the board box is locked with this lock to prevent unauthorized release in the first place. Japanese Patent Application Laid-Open No. 10-192518 discloses a technical idea of providing a number display mechanism so that the display changes each time unlocking is performed, and by managing the number of times of unlocking, it is possible to quickly find unauthorized unlocking. Are listed. Introduction of this product is as shown in FIG. 1, the lock 3 in the lid 1b of the substrate box 1 set only so as to lock the board box body 1a and the lid 1b in this tablet 3, the lock 3 cylinder 6 The display means 5 is attached to the front surface of the display, and the rotating plate 12 of the display means 5 is intermittently moved 90 degrees in one direction every time the lock 3 is unlocked by the ratchet mechanism using the ratchet wheel 13 and the ratchet claw. Further, after the rotation plate 12 makes one rotation, the rotation is blocked by the swing plate 14 or the like, and further unlocking operation is disabled.
On the front surface of the rotating plate 12, circle numbers indicating the remaining number of times of unlocking are displayed at intervals of 90 degrees, and this can be confirmed from a window hole provided in the lid 1b. When the unlocking operation is performed, the rotating plate 12 is rotated 90 degrees rightward and the round numbers visible from the window hole are replaced, so that the display of the round numbers confirmed from the window is changed. Then, when the display by the circled number is 1, when again further unlocking again locked, the window hole is blocked by the swing plate 14, together indicate that this again unlocked by is impossible capacity Further unlocking operations are mechanically blocked.
In the above prior art, the lock mechanism between the substrate box main body 1a and the lid 1b is a reversible lock mechanism using the cylinder lock 3, and a display means for displaying the number of times the lock is unlocked is provided. By managing it, it is possible to quickly confirm the presence or absence of unauthorized unlocking, so there is a need for an intermittent feed mechanism that attaches display means to the lock and intermittently drives it by unlocking operation, The mechanism structure becomes extremely complicated.
This is a lock mechanism for the board box body and lid, but this rotating plate displays the number of times of unlocking and manages this display so that it can be confirmed whether there is any unauthorized release. The idea is that it can be easily guessed that the present invention can also be applied to an attachment mechanism in which a board box is attached to a machine frame.
On the other hand, the sealing function required for the board box of the gaming machine only needs to guarantee that the board box has not been illegally released, and also requires a protective function in the sense of preventing the board box from being released. From this point of view, the protective function by the lock in the prior art is not always necessary.
[0004]
[Problems to be solved]
The present invention is based on the above recognition. Regarding the display of the number of times of releasing the board box, the locking mechanism is arranged so that the number of times of releasing the board box is displayed by a part of the board box locking mechanism. The challenge is to devise.
[0005]

[ 0007 ]
[Action]
The held portion is fixed to the holding portion by engaging the convex portion of the slider, which is linearly slidable on the held portion, with the first locking portion of the mounting bracket provided on the holding portion. The Thus, the state in which the convex portion is engaged with the first locking portion indicates that the held portion is fixed to the holding portion for the first time. The slider is stopped at the first fixed position by the positioning means.
Release the positioning of the slider by the positioning means, advance the slider, and remove the convex portion from the first locking portion of the mounting bracket (first releasing position), thereby holding the held portion to the holding portion. It becomes possible to separate from. When the slider is further advanced from the first release position to the second fixed position, the protrusion of the slider engages with the second locking portion, and the held portion is fixed to the holding portion again. It will be. The state in which the convex portion of the slider is engaged with the second locking portion indicates that the held portion and the holding portion are fixed once and then fixed again. In this way, the holding portion can be repeatedly fixed to the held portion by sequentially moving the slider forward. Since the slider cannot be moved backward by the ratchet mechanism (only forward movement is possible), each time the protrusion and the engaging portion are repeatedly engaged and disengaged, the position of the slider is surely sequentially moved forward, and the slider protruding portion The position at which the locking portion is engaged changes, and the number of times the held portion is removed from the holding portion can be visually confirmed depending on the engagement position.
[ 0008 ]

[Action]
A zigzag groove consists of two parallel transverse grooves that are fragmented in the longitudinal direction and a vertical groove that is perpendicular to the parallel transverse grooves, but when the positioning pin is in the stop position, the positioning pin Since the leading end of the groove coincides with one horizontal groove of the zigzag groove, the slider slides along the horizontal groove and comes into contact with the next vertical groove to position the slider at the locking position. On the other hand, when the positioning pin is moved to the release position, the tip of the positioning pin slides along the vertical groove and moves until it matches the other horizontal groove, so that the slider can advance. When the slider is advanced in this state, the tip of the positioning pin slides along the other lateral groove and further contacts the next vertical groove, and the advance operation stops. And the convex part of a slider remove | deviates from the latching | locking part of a mounting bracket in this position. When the positioning pin is returned to the stop position again, the tip of the positioning pin matches one of the lateral grooves, so that the slider can advance. Therefore, when the slider is advanced, the tip of the positioning pin further contacts the next vertical groove, and the advance operation stops. And the convex part of a slider engages with the following latching | locking part of a mounting bracket in this position. By selectively moving the positioning pin to the stop position and the release position in this manner, the forward movement of the slider is intermittently performed, and the stop position is surely stopped at the next release position and the next fixed position. The fixing operation and the releasing operation between the side and the held portion side can be easily and stably performed.

An embodiment of a gaming machine board box (corresponding to claim 1) of the present invention will be described with reference to the drawings.
Mounting brackets B and C are fixed to the inner surface of the machine frame A of the gaming machine, the left end of the board box D is locked to the mounting bracket B, the right end is fixed to the mounting bracket C, and the board box D is machined. The frame A is held.
The mounting bracket C is a U- shaped member having a lower side 21 and an upper side 22, and the lower side 21 is fixed to the machine frame A by a set screw s1 . The upper side 22 of the mounting bracket C is formed by arranging four locking portions 22a at a constant interval, and a notch 22b is formed between the locking portions 22a so as to form a comb-like portion as a whole. .
A cross-section “die back plate 23 is fixedly attached to the back side of the upper side 22 at intervals.
A square slider storage chamber 31 is provided at the right end of the substrate box body 30 of the substrate box D, and ratchet teeth 32 are formed on the bottom surface of the slider storage chamber 31.
A Z-shaped convex portion 41 protrudes from one side surface of the slider 40, and a staggered zigzag groove 42 is formed on the upper surface of the slider 40. As shown in FIGS. 3 and 7 , the zigzag groove 42 is formed by sequentially connecting horizontal grooves 42a and 42b arranged in a staggered manner and a vertical groove 42c perpendicular to the horizontal grooves.
The slider 40 is a hollow member whose bottom is released, and a ratchet claw 43 is fitted in a pocket p provided in the vicinity of the convex portion 41, and this ratchet claw 43 is biased by a spring 44, and its tip The inclined claws are engaged with the ratchet teeth 32.
A notch 51 is provided on one side of the cover plate 50 of the slider storage chamber 31 so that the convex portion 41 protrudes outward. A laterally long hole in the cover plate 50 is provided in the vicinity of the inner end of the notch 51. 52, and an elliptical recess 53 is provided on the back surface thereof.
The positioning pin 60 has a gripping shaft 62 protruding above the central annular flange 61 and a positioning shaft 63 protruding downward, and the gripping shaft 62 is inserted into the elongated hole 52 from below the cover plate 50. And protrudes from the upper surface. At this time, the annular flange 61 is fitted into the elliptical recess 53 on the back surface of the cover plate, and the positioning pin 60 is guided and held so as to be movable in the longitudinal direction of the long hole 52. Then, the positioning shaft 63 is inserted into the zigzag groove 42 of the slider 40 in a state in which the slider 40 is stored in the slider storage chamber 31, the cover plate 50 is fixed to the substrate box body 30 so that it cannot be removed and the slider storage chamber 31 is closed. Engage.
[0010]
Since the ratchet pawl 43 of the slider 40 is engaged with the ratchet teeth 32 on the bottom surface of the slider storage chamber 31, the slider can move rightward in FIG. 4, but cannot move backward. When the positioning pin 60 is at one end (stop position) of the long hole 52, the positioning shaft 63 is in a position where it can slide in one lateral groove 42a of the zigzag groove 42, and the positioning pin 60 is at the other end (release position) of the long hole 52. ), The positioning shaft 63 is in a position where the other lateral groove 42b of the zigzag groove 42 can slide.
When the slider 40 is at the left end ( position in FIG. 4 ) of the slider storage chamber 31, the convex portion 41 is outside the locking portion 22a at the left end of the upper side 22 of the mounting bracket C ( position in FIG. 3 ). The positioning pin 60 is positioned at one end of the long hole 52, and the convex portion 41 is operated to advance the slider 40 to the right in FIG. 3 or FIG . At this time, the positioning shaft 63 of the positioning pin 60 slides in the horizontal groove 42a of the zigzag groove 42, and comes into contact with the vertical groove 42c at the end thereof to stop the slider. At this time, the tip end portion of the convex portion 41 of the slider 40 enters between the upper side 22 of the mounting bracket C and the back plate 23 and is positioned below the left end locking portion 22a. Therefore, engages with the convex portion 41 is the left end of the engaging portion 22a, but the substrate box D is fixed to the mounting bracket C, fixed with screws s2 stop the convex portion 41 and the locking portion 22a in this position (FIG. 2) , the substrate box D is rigidly fixed to the mounting bracket C to be stabilized.
When the set screw s2 is removed and the positioning pin 60 is moved to the other end of the long hole 52, the positioning shaft 63 is positioned at the other lateral groove 42b of the zigzag groove 42, so that the slider 40 can be advanced again. . Therefore, when the slider is advanced, the positioning shaft 63 slides in the horizontal groove 42b and comes into contact with the vertical groove 42c at the end of the horizontal groove 42b, and the slider 40 stops at that position. And in this position, since the convex part 41 exists in the position of the leftmost notch 22b of the attachment bracket C, it becomes possible to remove the board box D from the attachment bracket C.
When the positioning pin 60 is moved again to one end (stop position) of the long hole 52 after the substrate box D is returned to its original position, the positioning shaft 63 is positioned at the position of one lateral groove 42a of the zigzag groove 42. The slider 40 can be moved forward. When the slider 40 is advanced in this state, the positioning shaft 63 slides in one horizontal groove 42a and comes into contact with the next vertical groove 42c to stop the advance of the slider. At this stop position, the tip of the convex portion 41 is positioned below the second locking portion 22a of the mounting bracket C and engages with this.
[0011]
As described above, the slider advances each time the substrate box D is removed and fixed again. And since the slider cannot move backward, the position of the slider cannot be arbitrarily returned. And whenever it removes, the position of the convex part 41 moves to the 2nd surface and the 3rd from the latching | locking part of the 1st surface of a mounting bracket. Since it is visually confirmed whether the convex portion 41 is engaged with the engaging portion 22a, by confirming the order of the engaging portions with which the convex portion 41 is engaged, the presence or absence of unauthorized release is determined. Can be surely discovered.
In order to facilitate the confirmation of the order of the locking portions 22a, it is preferable to display numbers on the locking portions 22a.
In the above embodiment, the positioning mechanism of the slider 40 is constituted by the zigzag groove 42 provided on the upper surface of the slider 40, the long hole 52 provided in the cover plate 50, and the positioning pin 60. Are provided in the cover plate 50, a long groove corresponding to the long hole 52 is provided on the upper surface of the slider 40, and the positioning shaft 63 of the positioning pin 60 is slidably engaged with the long groove to provide a positioning mechanism. It can also be configured. In this positioning mechanism, the positioning pin 60 also moves forward with the forward movement of the slider. However, since the effect is not different from the positioning mechanism of the above embodiment, this positioning mechanism is different from the positioning mechanism of the above embodiment. It is equivalent.
[0012]
[Other examples]
In the first embodiment, the positioning means using the zigzag groove 42 and the positioning pin 60 is employed. However, a linear groove 81 having a semicircular cross section is provided on the upper surface of the slider 40, and a large number of linear grooves 81 are provided in the linear groove 81 at predetermined intervals. A hemispherical recess 82 is provided, and the other cover plate 50 holds the locking ball 83, and the locking ball 83 is urged by a spring 84 to be slidably fitted into the linear groove 81. Positioning means can also be employed. When the positioning means is used, the slider 40 cannot be strongly stopped at the fixed position and the release position. However, when the locking ball 83 falls into the recess 82, the slider 40 is moved to the fixed position and the release position with a certain degree of strength. Since it can be stopped and held in that position, there is no particular inconvenience. This is inferior in operation stability to that of the above embodiment, but the mechanism is simple.
[0013]
When you apply this invention to a fixing mechanism of the substrate box body and its lid are (corresponding to claim 2), the same comb-shaped portion and the upper side 22 of the mounting bracket C provided on the substrate box body, the lid A slider storage chamber 31 is provided, in which the slider is stored.
[0014]
In addition, regarding the engagement structure between the locking portion 22a of the comb-like portion and the convex portion 41 of the slider, when the slider 40 is intermittently slid in one direction, a large number of locking portions in which the convex portions are arranged are arranged. Any mechanism that can be sequentially engaged with and disengaged from each other is provided. Therefore, a streak-like groove is provided on the end face of the mounting bracket , and a notch having a width that allows the convex part to be removed by notching this streak-like groove at a predetermined interval. A portion may be formed, and the tip of the convex portion may be slidably engaged with the groove.
[0015]
Further, a convex portion projecting from the held portion directly from, provided on the slider backward inability aspect advanceable in one direction by the ratchet mechanism to the mounting bracket (holder), cutout and the engagement portion on the slider part It is also possible to provide a comb-like portion composed of the following, and the protrusion can be sequentially engaged with and disengaged from the plurality of engaging portions of the comb-like member by advancing the slider. Such a configuration complicates the shape of the slider, so it is not always practical for a fixing mechanism for fixing the substrate box to the machine frame, but when applied to a fixing mechanism for fixing the lid to the substrate box body. Since the slider is provided on the substrate box main body, the structure is simplified as compared with the case where the slider is provided on the lid, and this is a practically desirable form.
[0016]
FIG. 9 shows another example of a mechanism that makes the slider 40 advanceable and non-retreatable. This thing is a pin trunnion 93 disposed on the slider, the rack gear 92 provided on the bottom surface of the slider accommodating chamber 31, engaging the upper Kipi trunnion 93 to the rack gear 92, which prevents the reverse rotation of the pinion 93 by the elastic claw 94. When the slider 40 moves forward, the pinion 93 rotates in the forward movement direction (clockwise direction in FIG. 9) while bending the elastic claw 94. However, since the tip of the elastic claw 94 abuts against the back surface of the teeth of the pinion 93, the pinion 93 cannot be reversed, and therefore the slider 40 cannot be retracted. Since this embodiment has a complicated mechanism, there is a problem that the cost is increased as compared with the embodiments shown in FIGS. 4 and 5 using the ratchet gear 32 and the ratchet pawl 43. However, this is superior in the smoothness of the forward movement of the slider.
[0017]
【The invention's effect】
In the form in which the present invention is applied to the fixing mechanism for fixing the substrate box to the machine frame, the slider is simply slid slightly without being positioned by the positioning means without using a special tool or instrument. Since the convex part of the mounting part is disengaged from one locking part of the comb-shaped part such as the mounting bracket, the board box can be removed from the mounting bracket, and the convex part of the slider can be Since it engages with the next locking portion of the comb-like portion, the substrate box can be fixed to the mounting bracket. Therefore, it is possible to easily and quickly attach and remove the board box.
Since the slider can only move forward and cannot move backward, each time the board box is removed and attached, its convex part always moves forward, and the locking part of the mounting bracket to which the convex part is engaged. The order changes. Therefore, by managing the order of the locking portions of the mounting bracket with which the convex portions are engaged, it is possible to easily confirm visually whether or not the substrate box has been removed without permission.
When the present invention is applied to the fixing mechanism between the substrate box main body and the lid, the same effects as described above are obtained.
