Even when the displacement limit position of the collar part in the locked state is reached , the collar part and the collar part restricting the displacement from the displacement limit position to the collar part unlocking side specific position side, The engagement state of the movable engagement portion is maintained,
When at least the collar part is in the collar part locking side specific position, an external force is directly applied to the movable engagement part, so that only the movable engagement part moves to the engagement part unlocking side specific position side. Even when the displacement reaches the displacement limit position of the movable engagement portion in the locked state, the movable engagement portion restriction that restricts the displacement from the displacement limit position toward the engagement portion unlocking side specific position side by means, and its gist that the engagement of the movable engaging portion and said hook portion is maintained.

  According to the gaming machine of the present invention, it is possible to provide a gaming machine with excellent defense performance against unauthorized unlocking using a wire or the like.

  As described above, generally, in a gaming machine such as a slot machine, the front door (door body) is provided so as to be openable and closable with respect to the housing (support member) from the viewpoint of maintenance and the like. For this reason, the gaming machine is provided with a locking device so that a person other than the store clerk cannot open the front door without permission. As such a locking device, a cylinder lock operated using a dedicated key, a plurality of hook members provided so as to be detachable with respect to a plurality of locked portions provided on the housing, and a cylinder with a key 2. Description of the Related Art There is a known one having a sliding hook that interlocks a plurality of hook members in accordance with an unlocking operation of the lock. In the locked state, the front doors cannot be opened with respect to the housing by engaging the respective hooked members with the corresponding locked portions. On the other hand, when the cylinder lock is unlocked with a dedicated key, the flange members are simultaneously detached from the locked portions via the sliding rod, and the front door can be opened.

  In recent years, in game halls, for example, unauthorized operation to acquire a lot of game media by unlocking the front door during business operations, illegally operating or exchanging control devices provided inside the housing, etc. Sometimes done. Such unauthorized unlocking is usually performed by inserting a wire such as a wire from the gap between the front door and the housing, and hooking the wire to the hook member of the locking device and moving it in the unlocking direction. When an unauthorized unlocking operation is performed on any one of the flange members, the operation is transmitted to the other flange member via the sliding rod, and the entire flange member is interlocked and detached from the locked portion. The front door can be opened.

  On the other hand, for example, when an unauthorized unlocking operation is performed on any one of the saddle members, the operation of the saddle member according to the unauthorized unlocking operation is not performed other than the unauthorized unlocking operation. Some have a mechanism for preventing transmission to the eaves member (see, for example, Patent Document 1).

  However, in the above prior art, a plurality of eaves members are provided apart in the vertical direction. That is, when the above-described unauthorized unlocking operation is performed, a plurality of objects to be hooked with the wire are separated. For this reason, it is relatively easy to hook the wire rods on the plurality of flange members, and the front doors may be unlocked by simultaneously displacing the plurality of flange members in the unlocking direction.

  Hereinafter, each means suitable for solving the above-described problems will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A door body supported to be openable and closable with respect to the support member;
A gaming machine including a locking mechanism that locks the door body with respect to the support member,
The locking mechanism is
A locking device provided on one of the support member or the door body, and an engaged means provided on the other,
The locking device is
A locking member operated by a key;
In conjunction with the operation of the locking member, it comprises at least a buttocks that can be displaced between the buttocks locking side specific position and the buttocks unlocking side specific position,
The engaged means is
A movable engagement portion displaceable between at least the engagement portion locking side specific position and the engagement portion unlocking side specific position;
When the collar portion and the movable engagement portion are in an engaged state, a locked state in which the opening of the door body is restricted,
When the collar portion and the movable engagement portion are in a disengaged state, the door body is unlocked and the unlocked state is allowed,
When closing the door body with respect to the support member without using the key,
At least the movable engagement part is displaced to the engagement part unlocking side specific position side, so that a relative displacement greater than or equal to a predetermined amount of the flange part and the movable engagement part necessary for closing the door body The quantity is obtained,
In the locked state, when there is a specific operation of the lock member by the key, at least the hook part is displaced to the hook part unlocking side specific position side, so that the disengaged state is achieved. A relative displacement amount greater than or equal to a predetermined amount of the flange portion and the movable engagement portion required for
In the locked state and in a state where there is no specific operation of the locking member by the key,
When at least the movable engagement portion is at the engagement portion locking side specific position, only the collar portion is displaced to the collar portion unlocking side specific position side, and the displacement limit of the collar portion in the locked state Even when reaching the position, the engagement state of the collar and the movable engagement portion is maintained,
When at least the collar part is in the collar part locking side specific position, only the movable engagement part is displaced to the engagement part unlocking side specific position side, and the movable engagement part in the locked state is moved. Even if the displacement limit position is reached, the engaged state of the movable engagement portion and the flange portion is maintained.

  According to the above means 1, in the locked state, the engagement state between the two is not released only by displacing only one of the collar portion and the movable engaging portion in the unlocking direction without using a key. Is not allowed to open. On the other hand, by operating the lock member with the key, at least the collar part is displaced in the unlocking direction, and when the collar part and the movable engagement part are displaced relative to each other by a predetermined amount or more, both are disengaged, Opening of the door body is allowed. Therefore, if the hook and the movable engagement portion are displaced in the unlocking direction by using a wire or the like and the engagement state between the two is illegally released, the hooks engaged with each other at a single location. Since a complicated operation such as hooking a wire rod or the like between the portion and the movable engagement portion or a complicated operation such as operating the hooked wire rod in a different direction is required, an unauthorized unlocking operation becomes difficult. As a result, the defense performance against unauthorized unlocking using a wire or the like is significantly improved. Further, when closing the door body without using a key, at least the movable engagement portion is displaced in the unlocking direction, so that a predetermined amount or more of the flange portion and the movable engagement portion necessary for closing the door body is required. A relative displacement amount is obtained. That is, the door body can be closed by displacing the movable engagement portion even if the collar portion is not displaced. In other words, the door can be closed without using a key (at least without performing the specific operation), which is highly convenient.

  The same applies to the following means. However, the number of the hooks and the movable engaging parts corresponding thereto is not limited to one, and a plurality of these may be provided.

  Examples of the lock member include a cylinder lock that is rotated by inserting a key. In this case, the operating part operated by the key is constituted by a lock shaft provided rotatably, an engagement piece (cam plate) fixed to the lock shaft, and the like. Of course, the lock member is not limited to the cylinder lock, but may be operated using a key such as a card key.

  Further, depending on the configuration, the “displacement limit position” of the collar part or the movable engagement part may be the same position as the “seal part unlocking side specific position” or the “engagement part unlocking side specific position”.

  In addition, the “non-engaged state” of the collar part and the movable engagement part is a positional relationship in which the collar part and the movable engagement part do not contact when the door body is moved in the opening / closing direction, or the door body while contacting. Indicates a state in which the can be opened. In other words, the “relative displacement amount greater than or equal to the predetermined amount” of the collar part and the movable engagement part necessary for opening and closing the door body is not related from the state where the both are located at their respective locking side specific positions (engagement state). It refers to the amount of relative displacement that is greater than or equal to a predetermined amount until reaching the combined state. For example, the hook portion and the movable engagement portion are engaged with each other with respect to the front-rear direction, which is the opening and closing direction of the door body, and when the door body is opened and closed, the portions with which the hook portion and the movable engagement portion are engaged are at least in the vertical direction (the door body). In a configuration that is displaced in a direction perpendicular to the opening / closing direction of the first and second members, a relative displacement amount of a predetermined amount or more in the vertical direction until both of them reach the non-engagement state is the “relative displacement of the predetermined amount or more It corresponds to “amount”.

Mean 2. A hook part restricting means for restricting displacement of the hook part toward the specific position side of the hook part unlocking side than the displacement limit position of the hook part in the locked state;
2. The gaming machine according to claim 1, wherein when the lock member is operated by the key, the restriction by the buttocks restriction means is released.

  According to the means 2, the configuration of the means 1 can be realized relatively easily by providing the collar part restricting means. That is, when an unlocking operation is performed using a key, the hook part is displaced by a predetermined amount or more in accordance with the operation, so that the movable engaging part at a specific position on the engaging part locking side is more than a predetermined amount. A relative displacement amount is obtained, and opening of the door body is allowed. On the other hand, when an external force is directly applied to the buttocks by a wire or the like without using a key, that is, when an unauthorized unlocking operation is performed, the displacement of the buttocks beyond a predetermined amount is restricted, and the Since the engagement state between the part and the movable engagement part is maintained, the door body is not allowed to be opened.

  In addition, in the structure provided with the said collar part control means, when it is going to close a door body without using a key, if a to-be-engaged means (engagement part) is fixed, a collar part and a Since the collision with the coupling means and the impact is relatively large, there is a possibility that problems such as deformation and breakage of the flange and the engaged means may occur. In this respect, in this means, since the movable engagement portion is configured to be displaced, even if the displacement of the flange portion is regulated, the relative amount of the flange portion and the movable engagement portion is more than a predetermined amount. Since the amount of displacement is ensured, the above problem is unlikely to occur. Therefore, when closing the door body, it is not necessary to perform a locking operation using a dedicated key, and convenience is improved. For example, the front end of the collar portion tapers in a substantially triangular shape, and when the door body is closed, first, the inclined portion of the collar portion contacts the movable engagement portion. Further, by closing the door body, the movable engagement portion is displaced in the unlocking direction against the urging force of the urging means such as a coil spring. And if a collar part gets over a movable engagement part, a movable engagement part will return to an original position with the urging | biasing force of a biasing means, will be in an engagement state with a collar part, and will be in a locking state.

Means 3. The locking device includes a transmission member that transmits the operation of the locking member to the collar portion,
When no key is inserted into the lock member, the operating portion of the lock member cannot be displaced by a predetermined amount or more, the displacement of the transmission member by a predetermined amount or more is restricted by the operating portion, and the transmission member 2. A gaming machine according to claim 1, wherein the displacement of the portion from the displacement limit position to the specific position side of the buttocks unlocking side is restricted.

  According to the means 3, the same effects as the means 2 can be obtained. For example, when the key is not inserted into the cylinder lock, the locked state of the cylinder lock is not released, and the transmission member engaged with the cam plate or the like of the cylinder lock and the collar portion are maintained in a state in which they cannot be displaced by a predetermined amount or more. An example is given. The configuration in which the displacement of the collar portion is regulated by the transmission member is, for example, a configuration in which the transmission member and the collar portion are integrally formed, and when the displacement of the transmission member is regulated thereby, the configuration in which the collar portion is not displaced, etc. Is also included.

  Means 4. Means 1 to characterized by comprising movable engaging part restricting means for restricting displacement of the movable engaging part from the displacement limit position to the specific position side of the engaging part unlocking side in the locked state. A gaming machine according to any one of means 3.

  According to the means 4, the configuration of the means 1 can be realized relatively easily by providing the movable engagement portion restricting means. In other words, when an external force is directly applied to the movable engagement portion by a wire or the like without using a key, that is, when an unauthorized unlocking operation is performed, the displacement of the movable engagement portion over a predetermined amount is restricted. And since the engagement state of the said movable engaging part and a collar part is maintained, opening of a door body is not accept | permitted. In addition, in the structure provided with both the above-mentioned buttocks regulating means and the movable engaging part regulating means, the unauthorized unlocking operation becomes more difficult. Therefore, the defense performance against unauthorized unlocking is further improved by the synergistic effect of both. Can do.

Means 5. The movable engagement portion regulating means is
A first state that regulates displacement of the movable engagement portion in the locked state;
Means 4 is characterized in that at least when the door body is closed with respect to the support member, it can be changed to a second state in which the flange portion and the movable engagement portion are allowed to be engaged. The gaming machine described.

  According to the above means 5, the door can be smoothly closed without being obstructed by the movable engagement portion restricting means, and convenience is improved.

Means 6. The movable engagement portion regulating means is
A restricting member displaceable between the first position and the second position;
Restriction member urging means for urging the restriction member toward the first position,
The restricting member assumes the first state by taking the first position,
The restriction member is configured to be in the second state by taking the second position,
When closing the door body with respect to the support member, at least the movable engagement portion is displaced to the engagement portion unlocking side specific position side by contact between the flange portion and the movable engagement portion. And
The regulating member is
When the movable engagement portion displaced to the engagement portion unlocking side specific position side comes into contact, it is displaced to the second position side against the urging force of the restriction member urging means,
6. The gaming machine according to claim 5, wherein when the collar portion and the movable engagement portion are engaged, the game device is brought into a non-contact state with the movable engagement portion and returns to the first position. .

  According to the means 6, by closing the door body, the state of the movable engagement portion regulating means is automatically changed, and the flange portion and the movable engagement portion are allowed to be in the engaged state. When engaged, the displacement of the movable engaging portion is regulated. Therefore, there is no need to perform any special operation when closing the door body, and convenience is improved. In addition, such an operational effect is that, when the door body is closed with respect to the support member, at least the movable engagement is caused by the contact between the flange portion and the movable engagement portion. In place of the configuration in which the portion is displaced toward the engagement portion unlocking side specific position side, at least when the door body is closed with respect to the support member, at least the movable engagement portion is unlocked from the engagement portion. A configuration in which the flange portion and the movable engagement portion are in contact with each other while being displaced toward the side specific position side can be obtained in the same manner.

  Mean 7 The game machine according to any one of means 4 to 6, wherein the movable engagement portion restricting means is configured not to be interlocked with an operation of the lock member in response to an operation by the key.

  According to the means 7, since the movable engaging part regulating means is configured not to be interlocked with the operation of the lock member, that is, not configured to interlock with the collar part or the transmission member, the collar part is temporarily formed by a wire or the like without using a key. Even when an unauthorized operation is performed on the transmission member, this stress is not transmitted to the movable engagement portion regulating means. That is, since the unlocked state cannot be achieved only by an unauthorized operation on the buttocks, the transmission member, etc., the defense performance against unauthorized unlocking is significantly improved. The configuration in which the movable engagement portion restricting means is not interlocked with the operation of the lock member can be realized by providing the movable engagement portion restricting means apart from each other without being engaged with the flange portion or the transmission member.

Means 8. When closing the door body with respect to the support member without using the key,
Necessary for closing the door body when the movable engaging part is displaced to the engaging part unlocking side specific position side and the hook part is displaced to the hook unlocking side specific position side. The gaming machine according to any one of means 1 to 7, wherein a relative displacement amount equal to or greater than a predetermined amount of the collar portion and the movable engagement portion is obtained.

  The configuration described in the above means 1 or the like by a configuration in which only one of the movable engagement portion and the collar portion is displaced toward the unlocked specific position when the door body is closed with respect to the support member without using a key. However, the structure of the locking mechanism may be complicated, but the structure of the means 8 for displacing both the movable engagement portion and the collar portion may be used to simplify the locking mechanism. be able to.

Means 9. A hook part biasing means for biasing the hook part toward the hook part locking side specific position side; and a movable engagement part biasing means for biasing the movable engagement part toward the engagement part locking side specific position side; With
When the door body is closed with respect to the support member, the collar part and the movable engagement part come into contact with each other, so that both the collar part and the movable engagement part have their own unlocking. The gaming machine according to any one of means 1 to 8, wherein the gaming machine is displaced to the side specific position side.

  According to the means 9, in addition to the same effects as the means 8, it is possible to disperse and reduce the load applied to each of the flange portion and the movable engagement portion when contacting each other. As a result, it is possible to reduce the occurrence of defects such as deformation and breakage in the buttocks and the like. When only one of them is displaceable and an attempt is made to obtain such an effect, an urging means having a relatively weak urging force may be used, but in this case, an illegal act as described above is performed. And there exists a possibility that a collar part and a movable engagement part can be easily displaced to the own unlocking side specific position side. In this respect, according to the present means, the individual urging means having a strong urging force is used to some extent, but the load is distributed to both, so that the impact force applied to each can be reduced.

Details of the locking mechanism composed of the locking device 600 and the support fitting 800 will be described later.

  A game panel 30 for notifying the player of the game state is provided above the center of the front door 12. In the game panel 30, three vertically long display windows 31L, 31M, 31R are formed side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, 31R. The display windows 31L, 31M, and 31R may be combined into a single display window.

  As shown in FIGS. 3 and 4, the inside of the housing 11 is vertically divided into two by a partition plate 40, and a reel unit 41 constituting variable display means is attached to the upper portion of the partition plate 40.

  The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R as rotating bodies formed in a cylindrical shape (annular shape). Each of the reels 42L, 42M, and 42R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, and 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, and 42R correspond to the display windows 31L, 31M, and 31R on a one-to-one basis. . Accordingly, a part of the surface of each reel 42L, 42M, 42R is visible through the corresponding display windows 31L, 31M, 31R. A belt-like belt is wound around the outer peripheral surface of each reel 42L, 42M, 42R, and a number of symbols as identification information are printed on the outer peripheral surface of the belt at regular intervals. When the reels 42L, 42M, and 42R rotate forward, the surfaces of the reels 42L, 42M, and 42R are projected as if moving from top to bottom through the display windows 31L, 31M, and 31R.

  Each of the reels 42L, 42M, and 42R is coupled to stepping motors 61L, 61M, and 61R (see FIG. 6) as driving means, and each reel 42L is driven by the stepping motors 61L, 61M, and 61R. , 42M, 42R can be rotated individually, that is, independently of each other. Then, when the drive shafts of the stepping motors 61L, 61M, and 61R are rotated, the reels 42L, 42M, and 42R are rotated about the drive shafts so as to rotate.

  The reel unit 41 is provided with reel index sensors 55L, 55M, and 55R (see FIG. 6). In the present embodiment, a transmissive photosensor in which a light emitting element and a light receiving element are held at a predetermined interval is employed as each of the reel index sensors 55L, 55M, and 55R. Each reel index sensor 55L, 55M, 55R detects that a sensor cut van (not shown) passes between both elements each time each reel 42L, 42M, 42R makes one round, and each time a main control described later is performed. A detection signal is output to the device 131. The main controller 131 can check and correct the rotational positions of the reels 42L, 42M, and 42R almost every round based on this detection signal.

  For example, in this embodiment, the stepping motors 61L, 61M, and 61R are set to rotate once by giving a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse, hereinafter the same). That is, each reel 42L, 42M, 42R is configured to rotate by a rotation amount corresponding to the number of drive signals such that each reel 42L, 42M, 42R changes by an angle of 5 ° with a drive signal of 7 pulses. Yes. Further, the rotational positions of the stepping motors 61L, 61M, 61R, that is, the rotational positions of the reels 42L, 42M, 42R are controlled by this drive signal.

  On each of the belts of the reels 42L, 42M, and 42R described above, a plurality of, specifically, 21 symbols are drawn in the long side direction (circumferential direction). Therefore, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. Based on the number of pulses from the time when the rotational positions of the reels 42L, 42M, and 42R are detected, it is possible to recognize which symbols are visible from the display windows 31L, 31M, and 31R. Control can be performed such that the symbols can be viewed from the display windows 31L, 31M, 31R.

  Of the symbols attached to the reels 42L, 42M, and 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, and 31R is mainly determined by the vertical lengths of the display windows 31L, 31M, and 31R. Is limited to a predetermined number. In this embodiment, three reels are provided. For this reason, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 5 shows a symbol arrangement drawn on the belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, each of the reels 42L, 42M, and 42R is provided with 21 symbols in a row. Although numbers 1 to 21 are assigned to the respective reels 42L, 42M, and 42R, these are given for convenience of explanation, and are not actually attached to the reels 42L, 42M, and 42R. . However, in the following description, the number is used for explanation.

  As a symbol, there are a “red 7” symbol (for example, the left belt 20th) and a “white 7” symbol (for example, the left belt 19th) as the first special symbol for shifting to the big bonus game. . In addition, there is a “BAR” symbol (for example, the 14th left belt) as the second special symbol for shifting to the regular bonus game. Further, there is a “replay” symbol (for example, the eleventh left belt) as a third special symbol for shifting to the replay game. In addition, a “watermelon” symbol (for example, the left belt ninth), a “bell” symbol (for example, the left belt eighth), and a “cherry” symbol (for example, left) as the small character symbols from which the small character is paid Belt 4th). As shown in FIG. 5, the number of various symbols and the arrangement order are completely different in the belts wound around the reels 42L, 42M, and 42R.

  A total of five combination lines are attached to the game panel 30 such that three display windows 31L, 31M, and 31R are connected to each other and three in parallel in the horizontal direction and two in diagonal directions. Of course, the maximum number of combined lines may be 6 or more, or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to these combination lines, effective line display sections 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (center line) of the combination lines is activated. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is displayed and notified by lighting or the like. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. A winning is awarded when the symbols are stopped in a predetermined combination on the activated combination line, that is, on the activated line, and a predetermined medal payout process, a transition process to a specific game, and the like are executed.

  Here, the payout number regarding each symbol when winning is explained. Regarding the small role design, when the “Watermelon” design is aligned with the left, middle and right on the active line, 15 medals are paid out. When the “Bell” design is aligned with the left, middle and right on the effective line Pays out 8 medals, and when the “cherry” symbol on the left reel 42L stops on the active line, 2 medals are paid out. That is, the “cherry” symbols of the middle reel 42M and the right reel 42R are irrelevant to the medal payout. In addition, for the “cherry” symbol, the medal payout is performed regardless of the combination with other symbols, and therefore, a plurality of effective lines of the left reel 42L overlap (specifically, the upper or lower row) with “ When the “cherry” symbol is stopped, medals are paid out by multiplying the number of overlapping active lines. As a result, in this embodiment, four medals are paid out.

  For other symbols, the combination of the first special symbol (Big Bonus symbol) “Red 7” symbol or “White 7” symbol on the same line with the left, middle and right symbols In the case of “BAR” symbol which is a combination of 15 medal payouts and second special symbols (regular bonus symbols), 15 medal payouts are also made when they are aligned with the left, middle and right on the active line. In the present embodiment, for example, the “red 7” symbol and the “cherry” symbol may be established at the same time, but the medal payout in this case is fifteen. This is because the upper limit number for one medal payout is set to 15.

  Further, when the “replay” symbol, which is the combination of the third special symbol, is aligned with the left, middle, and right on the active line, the medal payout is not performed. In other cases, that is, when the “cherry” symbol of the left reel 42L does not stop on the active line and the same symbols as the left, middle, and right are not aligned on the active line, no medal payout is performed.

  Here, the bonus game in the present embodiment will be described. The regular bonus (hereinafter referred to as “RB”) game is composed of 12 JAC games. The JAC game is a game in which only one bet is allowed, and is a game with a very high probability that JAC symbols (here, replay symbols are substituted) are aligned on the active line, that is, establishment of JAC symbols is very high. When a JAC symbol is established in a JAC game, the maximum number (15 in this case) of medals is paid out. When the JAC symbol is established 8 times, the RB game is ended even before the JAC game reaches 12 times. On the other hand, the big bonus (hereinafter referred to as “BB”) game is composed of 30 small role games and 3 JAC ins. A small role game is a game in which a small role is won with a high probability (“Bell” symbols etc. are on the active line), and JAC in means entering the JAC game 12 times. When JAC symbols are aligned on the active line, JAC in is established. The JAC game is the same as that of the RB game. Also, when the JAC game by the third JAC in is finished, the BB game is finished even before the small role game reaches 30 times, and before the JAC in reaches 3 times after the 30 small role games are finished. Even if there is, the BB game ends. The form of the bonus game is not limited to the above form, and may be a different form.

  The inserted medal detection sensor 75a is actually composed of a plurality of sensors. In other words, the storage passage 81 extending from the medal insertion port 75 to the hopper device 91 is configured such that medals can pass in one row at the upstream portion thereof. In addition, a first sensor is provided in the upstream portion of the storage passage 81, and the second sensor and the third sensor are close to the downstream side more than the width of the medal from the first sensor (a state in which the same medal is simultaneously detected at least at one time) The inserted medal detection sensor 75a is constituted by these first to third sensors. The main control device 131 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, the main control device 131 considers that there has been a medal clogging or fraud and makes an error. If an error occurs, an error notification is performed and an operation by the player until the error is canceled is invalidated. The main controller 131 also monitors the order in which the second sensor and the third sensor are turned on and off, both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. Only when the third sensor is turned on, both the second and third sensors are turned off, and when the time for switching to each on / off switching is within a predetermined time, it is determined that the medal has been normally taken in. Otherwise, an error is assumed. The reason for this is to prevent injustice that the medal is reciprocated in the vicinity of the inserted medal detection sensor 75a and misidentified as the medal inserted in addition to the clogging of the medal in the storage passage 81.

An opening operation detection sensor 630 is attached to the lower surface side of the attachment base 619. In this embodiment, a transmissive photosensor in which a light emitting element and a light receiving element are held at a predetermined interval is employed as the opening operation detection sensor 630. When the first sliding rod 610 is slid upward, that is, when the front door 12 is opened by the key K as will be described later, the protrusion 617 detects the opening operation detection sensor 630. The opening operation detection sensor 630 detects this, and outputs a detection signal to the main controller 131 described later. Based on this detection signal, main controller 131 can determine that front door 12 has been opened by key K.

  The support plate 603 is provided with a second slide rod 620 so as to be sandwiched between the support plate 603 and the first slide rod 610. However, the second sliding rod 620 is set to have a relatively short vertical length, from the vicinity of the upper end of the bulging portion 610a of the first sliding rod 610 to a position slightly above the opening operation detection sensor 630. It is provided corresponding to the section. Accordingly, the second sliding rod 620 is disposed along the upper piece portion 620 a disposed along the bulging portion 610 a of the first sliding rod 610 and the general portion of the first sliding rod 610. The lower piece 620b is formed with a step.

  The lower piece 620b of the second sliding rod 620 is provided with a first protruding piece 621 protruding from the lower end toward the inner side of the front door 12, and from the rear edge near the lower end to the inner side of the front door 12. A second protruding piece 622 that protrudes toward the side is provided. Correspondingly, insertion holes 623 and 624 are formed in the support plate 603, and both protruding pieces 621 and 622 are inward of the front door 12 from the support plate 603 through the insertion holes 623 and 624, respectively. It protrudes. The first projecting piece 621 functions as a manual operation unit for performing a reset operation as described later by sliding the second sliding rod 620 downward. On the other hand, the second projecting piece 622 functions as a detected portion detected by a reset detection sensor 640 described later.

  The support plate 603 is provided with a mounting base 625 that protrudes inward of the front door 12 at a position above the insertion holes 623 and 624. A reset detection sensor 640 is attached to the lower surface side of the attachment base 625. In the present embodiment, a transmission type photosensor similar to the opening operation detection sensor 630 is employed as the reset detection sensor 640. In a normal state, that is, when the second sliding rod 620 is at the reference position, the second protrusion 622 is inserted between both elements of the reset detection sensor 640. When there is a downward sliding displacement of the second sliding rod 620, that is, when there is a reset operation via the key K or the first protruding piece 621 as described later, the second protruding piece 622 is performed. Comes out from between both elements of the reset detection sensor 640, and the reset detection sensor 640 detects this and outputs a detection signal to the main controller 131 described later. Based on this detection signal, main controller 131 can recognize that a reset operation has been performed.

  Now, the first sliding rod 610 is biased downward by a coil spring C1 as a flange biasing means. More specifically, the coil spring C1 has one end hooked to the hook portion 641 provided at the substantially central portion in the vertical direction of the first sliding rod 610 and the other end provided on the back side of the mounting plate 602. The part 642 is hung.

  The second sliding rod 620 is biased upward by the coil spring C2. More specifically, the first sliding rod 610 is formed with a hook portion 643 at a position slightly below the bulging portion 610a, and a notch recess 644 is formed at the front edge portion at a position lower than that. . A hook portion 645 is formed near the lower end of the second sliding rod 620. Then, one end of the coil spring C2 is hooked on the hook portion 643 of the first sliding rod 610, and the other end protrudes to the outside of the front door 12 of the first sliding rod 610 via the notch recess 644.

  Normally, the first sliding rod 610 is held at the reference position as shown in FIG. 7 and the like by the tensile force of the coil spring C1. In this state, the flange members 611 and 612 engaged with the first sliding rod 610 are substantially pulled by the front end portions thereof being pulled downward and coming into contact with the lower regulating projections 647 and 648 provided on the support plate 603. The horizontal state is maintained (see FIG. 23). In addition, since the movement of the eaves members 611 and 612 is restricted by the lower restriction protrusions 647 and 648, the downward movement of the first sliding rod 610 is also restricted.

  When the first sliding rod 610 slides upward, the collar members 611 and 612 are rotationally displaced in conjunction with this. However, the flange members 611 and 612 are restricted from further rotation by contacting the upper restricting protrusions 649 and 650 provided on the support plate 603. In this state, the flange members 611 and 612 are inclined such that the front end side is up and the rear end side is down (see FIG. 24).

  Therefore, in the rotational displacement range of the flange members 611 and 612, the position where the flange members 611 and 612 are in contact with the lower restricting protrusions 647 and 648 corresponds to the specific position (reference position) of the flange locking side in the present embodiment. . On the other hand, the position where the collar members 611 and 612 contact the upper restricting protrusions 649 and 650 corresponds to the collar unlocking side specific position.

  On the other hand, the second sliding rod 620 is normally held at the reference position as shown in FIG. 7 and the like by the tensile force of the coil spring C2. In this state, the second sliding rod 620 is in a state in which the upward movement is suppressed by the projection pieces 621 and 622 being urged to the upper edge portion of the insertion holes 623 and 624. Further, in this state, as described above, the second protrusion 622 is in a state where it enters between both elements of the reset detection sensor 640. When there is a downward sliding displacement of the second sliding rod 620, the second protruding piece 622 comes out from between both elements of the reset detection sensor 640.

  A cylinder lock 700 serving as a lock member is attached to the wide portion 602a of the attachment plate 602. As shown in FIG. 19, the cylinder lock 700 includes a cylinder body 701 having a substantially cylindrical shape, a lock shaft 703 provided inside the cylinder body 701 and having a key hole 702 inside, and an outer periphery of the cylinder body 701.

  The cylinder body 701 is formed with a total of 16 through-holes 706, each of which is vertically connected to the inside and outside of the cylinder body 701. Correspondingly, 16 through holes 708 communicating with the respective through holes 706 are also formed in the lock shaft 703. The key hole 702 side of the through hole 708 is formed with a smaller diameter than other parts so that a receiving member such as a pin 714 described later does not fall into the key hole 702.

  A spring 709 is accommodated in each through hole 706. One end of the spring 709 is in contact with the outer cylinder 704, and a pedestal 711 is connected to the other end. Each through hole 708 accommodates a plurality of spacers 712, 713 and pins 714 so as to be supported by the pedestal 711. The pins 714, the spacers 712 and 713, and the pedestal 711 can move up and down in the through holes 706 and 708 by the expansion and contraction of the spring 709. Among these, the pin 714 can be projected and retracted in the key hole 702 through a small diameter portion of the through hole 708 on the key hole 702 side.

  With the above configuration, when the key K is inserted into the keyhole 702, the pins 714 and the like move up and down along the concave and convex shapes on both the upper and lower sides of the key K. When the key K is completely inserted, each pin 714 enters the key K groove as shown in FIG. 20, and the base end surface of the pin 714 or one end surface of the spacer 712 or 713 And the outer peripheral surface of the lock shaft 703 are flush with each other. As a result, when the key K is completely inserted, the lock shaft 703 can be rotated as the key K is rotated. That is, the cylinder lock 700 has an internal structure in which the lock shaft 703 cannot be rotated unless at least the key K is inserted into the key hole 702.

  In addition, a cam plate 720 that transmits the rotation operation of the key K inserted into the key hole 702 to the first sliding rod 610 or the second sliding rod 620 is fixed to the rear end portion of the lock shaft 703.

  The cam plate 720 includes a pair of upper and lower upper engaging claws 720a and lower engaging claws 720b. These engaging claws 720a and 720b are formed at predetermined intervals in the rotational direction of the cam plate 720.

  Accordingly, a pair of upper and lower upper engagement holes 725 and 726 into which the engaging claws 720a and 720b can enter and exit are formed in the bulging portion 610a of the first sliding rod 610. Similarly, the upper piece 620a of the second sliding rod 620 is formed with a pair of upper and lower upper engagement holes 727 and 728 through which the engagement claws 720a and 720b can enter and exit. A through hole 730 is formed in the bulging portion 603a of the support plate 603 so as not to hinder the operation of the engaging claws 720a and 720b.

  The engagement holes 725, 726 of the first sliding rod 610 and the engaging holes 727, 728 of the second sliding rod 620 are the bulging portion 610 a of the first sliding rod 610 and the upper piece of the second sliding rod 620. In the overlapping state of the part 620a, at least the upper engagement holes 725 and 727 and the lower engagement holes 726 and 728 are in communication with each other (see FIG. 21).

  On the first sliding rod 610 side, the upper engagement hole 725 located above the engagement holes 725 and 726 has a longer vertical formation section than the lower engagement hole 726. Has been. On the other hand, on the second sliding rod 620 side, the lower engagement hole 728 located below the engagement holes 727 and 728 has a longer vertical formation section than the upper engagement hole 727. Is set to As described later, when the cam plate 720 slides one of the first sliding rod 610 or the second sliding rod 620, the upper engaging claw 720a or the lower engaging claw 720b is not brought into contact with the other.

On the other hand, when the front door 12 is in an open state, the switch portion 820a protrudes from the switch body by separating from the rib 667 on the locking device 600 side (see FIG. 15).

  The open detection switch 820 outputs an on signal when the switch unit 820a is in the protruding state, and outputs an off signal when the switch unit 820a is in the immersive state. That is, when the front door 12 is in an open state, an ON signal is output from the open detection switch 820 to the main controller 131. Based on this ON signal, main controller 131 recognizes that front door 12 has been opened.

  Next, the operation of the locking device 600 and the support bracket 800 will be described in detail. As shown in FIG. 22, in the locked state of the locking device 600 and the support bracket 800, the first sliding rod 610 takes the reference position, so that the rod members 611, 612 are received by the receiving brackets 803, 803 as shown in FIG. Locking is performed on the back side of the engaging portions 803f and 804f of 804, and the opening of the front door 12 is restricted.

  In a state where the front door 12 is locked to the housing 11, the upward sliding of the upper receiving metal fitting 803 is restricted by the lock member 660. More specifically, the stopper portion 660e of the lock member 660 is positioned immediately above the protruding piece 803g of the receiving metal fitting 803, and the upward sliding of the receiving metal fitting 803 is caused by contact with this, except for the play width. It is practically regulated. That is, the position where the receiving metal 803 contacts the stopper 660e of the lock member 660 is the displacement limit position of the receiving metal 803 in the locked state.

  Further, in the closed state of the front door 12, as described above, due to the engagement between the cam plate 720 of the cylinder lock 700 and the stopper portion 731, the sliding displacement upward of the first sliding rod 610, and consequently the rod member The displacements of 611 and 612 in the unlocking direction are substantially regulated except for the play width. That is, the position of the flange member 611 in a state where the stopper portion 731 of the first sliding rod 610 is in contact with the cam plate 720 of the cylinder lock 700 becomes the displacement limit position of the flange member 611 in the locked state.

  When the front door 12 is opened, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated clockwise as viewed from the front side of the slot machine 10 (see FIG. 1). This operation corresponds to a specific operation in the present embodiment. As a result, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b comes into contact with the upper edge portion of the lower engagement hole 726 of the first sliding rod 610 [see FIG. 21 (b)]. However, since FIG. 21B is a view seen from the back side of the slot machine 10, the rotation direction of the cam plate 720 is the counterclockwise direction.

  Thereafter, as the cam plate 720 is further rotated, the lower engagement claw 720b pushes the first sliding rod 610 upward against the tensile force of the coil spring C1. At this time, a space is provided in the upper portion of the lower engagement hole 728 through which the lower engagement claw 720b is inserted so that the lower engagement claw 720b is displaced upward. In the process of pushing up the moving rod 610, the lower engaging claw 720b does not come into contact with the second sliding rod 620 so that its operation is not hindered. Of course, in this case, since the cam plate 720 slides the first sliding rod 610, the stopper portion 731 does not act.

  When the first sliding rod 610 slides upward, as shown in FIG. 24, the collar members 611 and 612 are rotated, and the engagement with the engaging portions 803f and 804f of the metal fittings 803 and 804 is released. . In other words, the flange members 611 and 612 and the metal fittings 803 and 804 are in a disengaged state. As a result, the locking device 600 and the support fitting 800 are unlocked, and the opening of the front door 12 is allowed. Therefore, the relative displacement amount in the vertical direction between the head portions 611b and 612b of the flange members 611 and 612 and the engaging portions 803f and 804f of the receiving metal fittings 803 and 804 is the relative displacement amount necessary for the disengagement state. It is.

  Moreover, when the front door 12 is opened, when the force of the hand operating the key K is loosened, the first sliding rod 610 is pulled downward by the tensile force of the coil spring C1, and returns to the reference position. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

  As described above, in this embodiment, when the key K is not inserted into the key hole 702 of the cylinder lock 700, the sliding of the first sliding rod 610 is restricted, but the front door in the open state When locking 12, it is devised so that it can be locked without using the key K.

  More specifically, as shown in FIG. 25, when the front door 12 is closed from the opened state of the front door 12 in which the locking device 600 and the support fitting 800 are unlocked, first, the hook members 611 and 612 are moved. The inclined portions 611c and 612c of the head portions 611b and 612b come into contact with the lower sides of the engaging portions 803f and 804f of the receiving brackets 803 and 804 (see FIG. 26).

  At this time, as described above, since the displacement in the unlocking direction of the first sliding rod 610 and thus the rod members 611 and 612 is substantially regulated except for the play width, the front door 12 is further closed. As shown in FIG. 27, although the collar members 611 and 612 are slightly rotated and displaced, they are not largely displaced, and maintain a slightly rotated state at the displacement limit position in the locked state. For this reason, the receiving metal fittings 803 and 804 mainly slide upward against the tensile force of the coil springs C4 and C5.

  As shown in FIG. 27, in the upper receiving metal fitting 803 that has slid upward, the protruding piece 803g at the front end of the upper piece 803c contacts the stopper 660e of the lock member 660 from the front. Thereby, the lock member 660 is pushed by the receiving metal fitting 803 and rotates, and the lower side is displaced rearward. That is, when the front door 12 is closed, the lock member 660 does not get in the way. This position (state) corresponds to the second position (second state) of the lock member 660 in the present embodiment.

  After that, when the head portions 611b and 612b of the flange members 611 and 612 exceed the engaging portions 803f and 804f of the receiving metal fittings 803 and 804, the engaging portions 803f and 804f are locked by the locking recess 611a by the tensile force of the coil springs C4 and C5. , 612a so that the metal fittings 803 and 804 return to their original positions, and the heads 611b and 612b of the flange members 611 and 612 are locked to the engaging portions 803f and 804f of the metal fittings 803 and 804 ( (See FIG. 23). Therefore, at this time, the relative displacement in the vertical direction between the head portions 611b and 612b of the flange members 611 and 612 and the engaging portions 803f and 804f of the receiving metal fittings 803 and 804 is the same as the engaging portions 803f of the head portions 611b and 612b. , 804f, a relative displacement amount necessary to get over the vehicle, that is, a relative displacement amount necessary to close the front door 12.

  When the catches 803 and 804 return to their original positions, the lock member 660 also returns to its original position, and the stopper portion 660e of the lock member 660 is located immediately above the protruding piece 803g of the upper piece 803c of the catch 803. It becomes a state. As a result, locking is completed and the opening of the front door 12 is regulated, and the upward sliding of the receiving metal fitting 803 by the lock member 660 is substantially regulated except for the play width, that is, It becomes a locked state (locked state).

  Next, the reset operation will be described in detail. In the closed state of the front door 12, the second projecting piece 622 is in between the two elements of the reset detection sensor 640 as described above by taking the reference position of the second sliding rod 620.

  When the reset operation is performed in the closed state of the front door 12, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated counterclockwise when viewed from the front side of the slot machine 10. As a result, the cam plate 720 rotates in the same direction, and the upper engagement claw 720a contacts the upper edge portion of the upper engagement hole 727 of the second sliding rod 620 (see FIG. 21C). However, since FIG. 21C is a view seen from the back side of the slot machine 10, the rotation direction of the cam plate 720 is the clockwise direction.

  Thereafter, as the cam plate 720 is further rotated, the upper engaging claw 720a pushes the second sliding rod 620 downward against the tensile force of the coil spring C2. At this time, a space for the upper engagement claw 720a to be displaced downward is secured below the upper engagement hole 725 of the first sliding rod 610 through which the upper engagement claw 720a is inserted. In the process of pushing down the moving rod 620, the upper engaging claw 720a does not come into contact with the first sliding rod 610 so that the operation is not hindered.

  When the second sliding rod 620 slides downward, the second protruding piece 622 comes out from between both elements of the reset detection sensor 640, and the reset detection sensor 640 detects this, and a detection signal is sent to the main controller 131 described later. Is output. Based on this detection signal, main controller 131 can recognize that a reset operation has been performed. Thereby, reset of error states, such as a hopper error, can be performed, without opening the front door 12, for example.

  Then, when the force of the hand operating the key K is loosened, the second sliding rod 620 is pulled upward by the tensile force of the coil spring C2, and returns to the reference position. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

  On the other hand, in the opened state of the front door 12, the same reset operation as described above can be performed by manually operating the first protruding piece 621 and sliding the second sliding rod 620 downward. As described above, the slot machine 10 has a backup function for various data. Even if a power failure occurs, the slot machine 10 maintains the state at the time of the power failure, and at the time of recovery from the power failure (power recovery), It is possible to return to the state of. Therefore, if the power supply is shut down by a normal procedure as in the case where the game hall is closed, the state before the power shut-off is stored and retained. It is supposed to be reset.

  As described above in detail, in this embodiment, when the key K is not inserted into the cylinder lock 700, the first sliding rod 610 is slid upward by the engagement of the cam plate 720 and the stopper portion 731. The dynamic displacement and thus the displacement of the flange members 611 and 612 in the unlocking direction are substantially regulated except for the play width.

  Further, by providing the lock member 660, in the closed state of the front door 12, the displacement of the receiving metal fitting 803 in the unlocking direction is substantially regulated except for the play width.

  As a result, in the locked state, an external force is applied directly to the flange member 611 and the receiving metal fitting 803 using a wire or the like, and the engagement state between the both is incorrect by displacing the flange member 611 and the receiving metal fitting 803 in the unlocking direction. Even if it tries to release, the engagement state of both is maintained, so that the front door 12 is not allowed to open. Of course, in this embodiment, even if both are displaced to the displacement limit position in the locked state at the same time, the engagement state of both is maintained, so that the defense performance against unauthorized unlocking is very high.

  Furthermore, since the lock member 660 has a configuration that is not interlocked with the operation of the cylinder lock 700 in response to an operation with the key K, that is, a configuration that is not interlocked with the flange members 611, 612, the first sliding rod 610, and the like. Even if an unauthorized operation is performed on the eaves members 611 and 612 and the first sliding eaves 610 without using them, this stress is not transmitted to the lock member 660. That is, since the unlocked state cannot be achieved only by an unauthorized operation on the flange members 611, 612, the first sliding rod 610, etc., the defense performance against unauthorized unlocking is significantly improved.

  On the other hand, by operating the cylinder lock 700 with the key K, the hook members 611 and 612 are displaced in the unlocking direction, and a relative displacement amount equal to or greater than a predetermined amount of the hook members 611 and 612 and the metal fittings 803 and 804 is obtained. And both will be in a non-engagement state and open | release of the front door 12 is accept | permitted.

  As described above, in the configuration in which the displacement of the hook members 611 and 612 is restricted when the key K is not inserted into the cylinder lock 700, the key K is assumed to be temporarily fixed to the receiving metal fittings 803 and 804. When trying to close the front door 12 without using it, the collar members 611 and 612 collide with the metal fittings 803 and 804, and the impact is relatively large, so that the collar members 611 and 612 and the metal fittings 803 and 804 There is a risk of problems such as deformation and breakage. In this regard, in this embodiment, since the receiving metal fittings 803 and 804 are configured to be displaced, even if the displacement of the eaves members 611 and 612 is regulated, Since a relative displacement amount equal to or greater than a predetermined amount is ensured, the above problem is unlikely to occur. Therefore, when closing the front door 12, there is no need to operate the cylinder lock 700 using the key K, which is highly convenient.

  Further, when the front door 12 is closed, the flange members 611 and 612 and the metal fittings 803 and 804 come into contact with each other and are displaced in the unlocking direction. When the front door 12 is closed, the lock member 660 is automatically changed in its state by the contact of the metal fitting 803 and returned to the original state after the hook member 611 and the metal fitting 803 are engaged. The convenience is further improved.

  In addition, since both the flange members 611 and 612 and the metal fittings 803 and 804 are configured to be displaceable, it is possible to disperse and reduce the load applied to each of them when they are in contact with each other. As a result, it is possible to reduce the occurrence of defects such as deformation and breakage in the flange members 611, 612 and the like. When only one of them is displaceable and it is intended to obtain such an effect, the coil spring C1 or the like having a relatively weak biasing force may be used. In this case, fraudulent acts using a wire or the like may occur. If it is performed, there is a possibility that the flange members 611, 612 and the like can be easily displaced in the unlocking direction. In this regard, according to the present embodiment, the load is distributed to both the flange members 611 and 612 and the metal fittings 803 and 804 while using a strong biasing force to some extent as each coil spring. Individual impact force can be reduced.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the cam plate 720 and the stopper portion 731 are engaged to restrict the displacement of the hook members 611 and 612 in the unlocked state in the locked state, or by providing the lock member 660, so that the locked state is achieved. In this configuration, the engagement of the hook member 611 and the metal fitting 803 is not released by an unauthorized unlocking operation using a wire or the like by restricting the displacement of the metal fitting 803 in the unlocking direction. Not limited to this, it is also possible to adopt a configuration in which at least one of the restricting means for restricting the displacement of the flange members 611 and 612 and the restricting means for restricting the displacement of the metal fitting 803 are omitted. That is, at least both the flange members 611 and 612 and the receiving metal fittings 803 and 804 are configured to be displaceable, and only one of the flange members 611 and 612 and the receiving metal fittings 803 and 804 is not unlocked without using the key K. If the configuration is such that the engagement state between the two is not released by simply displacing, when an unauthorized unlocking operation using a wire or the like is attempted, the hook members 611 and 612 and the catches 803 and 804 are respectively hooked. Therefore, it is difficult to perform an unauthorized unlocking operation because a complicated operation such as operating a wire rod in different directions is required. As a result, the defense performance against unauthorized unlocking using a wire or the like is significantly improved as compared with the prior art.

  Further, when the front door 12 is closed without using the key K, at least the receiving fittings 803 and 804 are displaced to the unlocking side, so that the flange members 611 and 612 and the receiving fitting necessary for closing the front door 12 are disposed. It is sufficient that a relative displacement amount equal to or greater than a predetermined amount of 803 and 804 is obtained. However, in the case where the lock member 660 for restricting the displacement of the receiving metal fitting 803 is omitted, the relative displacement necessary for opening the front door 12 even when the receiving metal fittings 803 and 804 are at the displacement limit position in the locked state. Since it is necessary to prevent the amount from being obtained, when the front door 12 is closed, the flange members 611 and 612 need to be displaced to some extent.

  (B) The configuration of the flange members 611 and 612 is not limited to the above embodiment. For example, a configuration in which the flange members 611 and 612 are integrally formed with the first sliding rod 610 and slidingly displaced in the vertical direction may be employed.

  (C) The number of the flange members 611 and 612, the metal fittings 803 and 804, and the lock members 660 corresponding thereto are not limited to the above embodiment.

  For example, it is good also as a structure provided with a pair or 3 or more pairs of the eaves members 611,612 and the receiving metal fittings 803,804.

  In the above embodiment, the lock member 660 is provided only for the upper receiving metal fitting 803, but may be provided only for the lower receiving metal fitting 804, or both receiving metal fittings 803 and 804. It may be provided corresponding to each. In order to improve the defense performance against unauthorized unlocking, when there are a plurality of metal fittings, it is preferable to provide a lock member 660 corresponding to each. However, if it is provided corresponding to at least one, the defense performance against unauthorized unlocking can be sufficiently exhibited. In particular, if the lock member 660 is provided corresponding to the upper receiving metal fitting 803 as in the above embodiment, it is necessary to perform the illegal action in the game hall or the like while standing up from the seat. The deterrent effect is high.

  Moreover, in the said embodiment, although the locking member 660 as a movable engagement part control means (regulation member) is provided in the locking device 600, it is also possible to have a configuration provided in other parts such as the front door 12 and the housing 11. Good.

  (D) The structure of the metal fittings 803 and 804 is not limited to the above embodiment. For example, the receiving metal fittings 803 and 804 may be configured to move up and down and be capable of rotational displacement.

  Moreover, in the said embodiment, when closing the front door 12, the receiving metal fittings 803 and 804 are displaced to the unlocking direction by contacting the collar members 611 and 612. For example, the metal fittings 803 and 804 may be displaced by the electric driving means when the front door 12 is opened and closed. As a specific example, for example, a configuration in which the metal fittings 803 and 804 are displaced by controlling a solenoid or the like according to detection results of the opening detection switch 820 or the opening operation detection sensor 630 can be cited.

  (E) The configuration of the lock member 660 is not limited to the above embodiment. For example, in the above-described embodiment, when the front door 12 is closed, the lock member 660 is automatically rotated and displaced by the contact of the metal fitting 803, and returns to the original state after the engagement of the flange member 611 and the metal fitting 803. It has become. On the other hand, for example, a lock member that slides in a substantially horizontal direction may be employed. In addition, instead of being displaced by contact with the receiving metal fitting 803, for example, when the front door 12 is opened and closed, the first state where the displacement of the receiving metal fitting 803 is regulated by the electric drive means, the flange member 611 and the receiving metal fitting 803. It is good also as a structure which can change to the 2nd state which accept | permits that it will be in an engagement state. Specific examples include a configuration in which the lock member is displaced by controlling a solenoid or the like according to detection results of the opening detection switch 820 or the opening operation detection sensor 630, for example. Further, when such a configuration is adopted, a configuration for restricting the movement of the solenoid, the lock member, etc. so that the solenoid, the lock member, etc. are not displaced by an unauthorized unlocking operation without using the key K, etc. It is preferable to provide. For example, when the lock member can be displaced only via a plunger driven by excitation / non-excitation of a solenoid or a link member linked to the plunger, and the lock member is illegally displaced by hooking a wire or the like on the lock member An example of a configuration in which the lock member is not displaced by being restricted by a plunger or a link member is given as an example. Furthermore, by providing a cover member or the like that covers the solenoid so that a wire or the like cannot be hooked on the plunger or the link member, the defense performance against fraud can be enhanced.

  (F) The cylinder lock 700 of the above embodiment is locked when the key K is not inserted, and the cam plate 720 cannot be displaced. Then, by the engagement of the cam plate 720 and the stopper portion 731 in the locked state, the upward sliding displacement of the first sliding rod 610 and consequently the displacement of the rod members 611 and 612 in the unlocking direction are restricted. . Not limited to this, a cylinder lock different from the cylinder lock 700 may be adopted. For example, a cylinder lock in which the cam plate 720 cannot be displaced even when the key K is not inserted may be employed. However, in this case, in order to enhance defense control against an unauthorized unlocking operation directly performed on the scissors members 611 and 612 and the first sliding scissors 610 without using the key K, the scissors members 611 and 612 are enhanced. Alternatively, it is preferable to provide other restricting means for restricting the displacement of the first sliding rod 610. Of course, depending on the balance with the metal fittings 803 and 804, the engagement state with the metal fittings 803 and 804 can be achieved even if an unauthorized unlocking operation without using the key K is performed at the time of locking without providing a regulating means. It can be set as the structure which is not cancelled | released.

  Of course, the lock member is not limited to the cylinder lock, but may be operated using a key such as a card key.
