  First, invention groups that can be extracted from the present embodiment are shown as means n (n = 1, 2, 3,...), And will be described while showing effects and the like as necessary. In the following, for ease of understanding, the corresponding configuration in the present embodiment is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

  The following means are as follows: “As a gaming machine of this type, in a slot machine, a reel device, a medal payout device, various control devices (including a main board), a power supply device, etc. are mounted inside the case. A door body that can be opened and closed on the side is provided with a medal insertion device, a start lever, a stop button, etc. When playing a game, a player may insert a medal (or bet operation) or start operation every time the game is played. As a result, the reel of the reel device starts rotating, and the symbols attached to the outer peripheral surface of the reel device are variably displayed through the display window.After the reel starts rotating, the player presses the stop button. Alternatively, the reel stops rotating after a predetermined time has passed, and a letter of profit such as a medal payout according to the stop pattern visually recognized through the display window when the reel is stopped. In recent years, the reel device and the main board are mounted on a frame-shaped support body in response to the fact that the cycle of changing the machine model has become shorter. A separate slot machine is disclosed in which a display unit (replacement unit) is configured, and the display unit is detachably provided inside the housing. There has been proposed one in which a mounting plate for mounting the unit is provided and the display unit is mounted by moving the support on the mounting plate (see, for example, Patent Document 1). In order to facilitate the replacement operation of the unit, there has also been proposed one provided with a roller for assisting movement in the front-rear direction on the back side bottom portion of the support (see, for example, Patent Document 2). Isolated type In a display machine, after the display unit is completely mounted in the housing, the display unit is fixed using a clip-shaped fastener or the like in order to prevent movement inside the housing. When fixing the display unit by using the display unit, it is necessary to insert a hand into the casing and fix and remove the fasteners etc. while the display unit is stored in the casing. Normally, the work space is limited when the display unit is housed in the housing, and it is concerned that the above-described work may be very time-consuming. ” It is a thing.

Means 1. A housing (housing 11) opened in front of the gaming machine;
By having a plurality of revolving bodies (reels 655 to 657) in which a plurality of types of patterns are arranged in the circumferential direction, the main control apparatus (main control apparatus 770) that performs various controls relating to games is rotated. A display unit (replacement unit 400) in which a pattern display device (reel device 650) for variably displaying a pattern is mounted in a unit body (inner housing 410);
A support member (support rail 300) provided in the housing and movably supporting the unit body in the housing;
In a gaming machine in which the unit main body is in contact with the support member and the display unit is moved to the back side of the housing and attached to the housing.
The housing is provided with a case-side locking tool (upper guide portion 350a of the support rail 300), and the display unit is provided with a unit-side locking tool (lever member 610). The unit side locking tool is a movable member,
When the display unit is mounted on the housing, the unit-side locking tool is operated as the display unit is moved to the mounting completion position, and the unit-side locking tool is moved by the movement. A gaming machine characterized by being configured to be in a locked state.

  In the gaming machine of means 1, a display unit in which the main controller and the picture display device are mounted on the unit main body is configured to be detachable from the inside of the housing. At the time of detachment, the unit main body comes into contact with the support member. The display unit is moved in the state. When the display unit is mounted, the display unit is pushed in contact with the support member, and the unit side locking tool operates as the display unit moves to the mounting completion position. And the housing-side locking tool are locked. Thereby, the position shift of the display unit in the mounting completion state can be suppressed. That is, it is possible to prevent the display unit from being moved from the mounting completion position without requiring a separate operation other than the pressing operation of the display unit. By not requiring separate work in this way, it is possible to avoid the inconvenience that the operator forgets to perform the display unit movement restriction work. Further, by moving the display unit in contact with the support member, the trajectory is easily stabilized. For this reason, even if it does not push in a display unit, confirming the positional relationship of both locking tools visually, the position shift of both locking tools can be suppressed and transfer to a locked state is attained.

  In addition, if at least the unit side locking tool is a movable member (operational configuration) of both locking tools, the housing side locking tool can be fixedly attached, and the configuration of the housing side locking tool can be simplified. Can be achieved. In other words, it is possible to reduce the size of the housing side locking tool and reduce the protrusion to the inside of the housing. As a result, it is possible to suppress the inconvenience that the unit main body and the case-side locking tool are caught when the display unit is attached / detached, which can contribute to the ease of attaching / detaching the display unit.

  Mean 2. The unit side locking tool is provided on a side of the pattern display device, and the locking operation of the unit side locking tool is performed along the side plates (side plates 11d and 11e) of the housing. A gaming machine according to means 1.

  According to the means 2, the unit side locking tool is provided on the side of the pattern display device, and the unit side locking tool is configured to lock in the direction along the side plate of the casing. That is, the locking operation of the unit side locking tool is performed on a virtual plane that is parallel or substantially parallel to the side plate of the housing. For this reason, it becomes easy to avoid inconveniences such as the unit side locking tool protruding to the inside of the housing by its operation and buffering with other members such as the picture display device and the main control device. It is only necessary to secure the installation space for the case side locking tool in the direction intersecting the side plate of the case in the case, and it is not necessary to secure the locking operation space for the unit side locking tool. Therefore, it is possible to reduce a spatial restriction in a direction intersecting with the side plate in the housing.

  Further, for example, assuming that the unit-side locking device is locked by operating in a direction orthogonal to the side plate of the housing (that is, the left-right direction in the front view of the gaming machine), There is a possibility that the locking operation direction coincides with the variation direction (for example, the left-right direction) of the display unit mounting position. That is, since the mounting position of the display unit varies in the direction orthogonal to the side plate, the locking operation direction of the unit side locking tool and the display unit mounting position variation direction may be the same direction. In this way, when the locking operation direction of the unit side locking tool and the variation direction of the display unit mounting position are the same direction, the interval between both locking tools changes according to the mounting position variation of the display unit, There is a possibility that inconveniences such as a change in the degree of engagement of these locking tools occur. On the other hand, when the unit side locking tool is configured to lock in the direction parallel to or substantially parallel to the side plate of the housing as described above, the locking direction of the unit side locking tool and the position of the display unit The variation direction (for example, the left-right direction) intersects, and the locking operation direction and the position variation direction are not the same. For this reason, even if the display unit is mounted with left and right positional variations, it is possible to avoid the inconvenience that the left and right engaging devices are biased due to the positional variations.

  Means 3. The gaming machine according to means 1 or 2, wherein both the housing side locking tool and the unit side locking tool are provided at a plurality of locations.

  According to the means 3, since the housing side locking tool and the unit side locking tool are provided at a plurality of locations, it is possible to more suitably suppress the positional deviation of the display unit in the mounting completion state. In addition, since all of the respective locking tools are shifted to the locked state by the pushing operation of the display unit, an increase in work load at the time of mounting can be avoided even when there are a plurality of locking tools.

  For example, each locking tool may be provided on both the left and right sides of the pattern display device (unit main body). In this way, by providing the respective locking tools apart from each other on the left and right sides, it is easy to inconvenience that the display unit is displaced in the rotation direction centering on the locking position on one side (rotation direction in plan view of the gaming machine). Can be suppressed.

  In consideration of the workability of mounting the display unit on the housing, it may be difficult to completely suppress the movement of the display unit in the left-right direction within the housing. That is, there is a possibility that the display unit can move in the left-right direction within a predetermined margin within the housing. Here, as described in the means 2, if the configuration is such that the locking operation direction of the unit side locking tool is a direction along the side plate of the housing (a direction parallel to or substantially parallel to the side plate), the unit side locking The locking operation direction of the device (that is, the relative position direction between the housing side locking device and the unit side locking device) intersects with the assumed position variation direction of the display unit (for example, the left-right direction), and these locking operations Direction and misalignment direction are not the same. For this reason, even if the display unit is mounted with its position varied from side to side, there is little inconvenience that the degree of engagement of the locking tools on both the left and right sides is biased due to variation in the position. For example, even when the display unit is mounted in a state of being shifted to the right side, it is difficult to cause inconvenience that the degree of engagement of the left side locking tool is reduced. Therefore, it is possible to avoid the inconvenience that the left and right latches are less likely to be hooked due to variations in the left and right positions of the display unit, and the latches are easily detached.

  Means 4. 4. The gaming machine according to claim 1, wherein a biasing member (plate spring 631) for biasing the unit side locking tool to a locked position is provided in the unit main body.

  According to the means 4, the unit side locking tool is biased to the locked position by the biasing member. Thereby, it becomes easy to maintain the locked state of both locking tools. Even if a fraudster shakes the gaming machine for the purpose of releasing the locked state, it may be difficult to cause the inconvenience that the unit side locking device is separated from the housing side locking device. it can.

  Means 5. The display unit includes a supported member (slide rail 510 and roller 540) supported by the support member when the display unit is attached to and detached from the housing, and the unit body is mounted with the supported member. A gaming machine according to any one of means 1 to means 4, further comprising a mounting portion (for example, an accommodation recess 452) to which the unit-side locking tool is mounted.

  According to the means 5, both the supported member and the unit side locking tool are mounted on the mounting portion of the display unit. For example, a recess for accommodating the supported member may be provided in the side wall portion (side plate portions 410d and 410e) of the unit main body, and the unit side locking tool may be mounted in the recess together with the supported member. By providing both the supported member and the unit side locking tool in the recess, it becomes easy to bring the support position (height) of the display unit close to the locking position (height) of the locking tool. By bringing the support position and the locking position close to each other, it is possible to reduce the influence exerted on the shift of each locking tool to the locked state due to the vertical position variation when the display unit is mounted. In other words, the relative positions of the locking devices on the housing side and the unit side are less likely to vary, and the transition to the locked state can be made more reliable.

  Means 6. The unit side locking tool is configured to be switchable between two states of a locking state and a locking release state, and the unit side locking tool is an operation unit that performs a locking release operation from the front side of the gaming machine ( The gaming machine according to any one of means 1 to means 5, comprising an operation unit 615).

  According to the means 6, the operation part is provided in the unit side locking tool. By operating the operation unit using a finger or a hand, the locked state between the unit side locking tool and the housing side locking tool is released. Since the locked state can be released without using a special instrument or the like, the work can be easily performed even when the display unit is removed.

Mean 7 The housing side locking tool is provided with a holding portion (standing portion 354) that holds the unit side locking tool at a position where the unit side locking tool is switched to the unlocked state.
When the operation unit is operated in the state where the display unit is completely mounted, the unit-side locking tool is held at the unlocking position, while the display unit is moved from the mounting completion position to the front side of the gaming machine. The gaming machine according to claim 6, wherein the holding of the unit-side locking member by the holding portion is released.

  According to the means 7, when the display unit is detached, it can be switched to the unlocked state by operating the operation part of the unit side locking tool with a finger or a hand. Further, the unit-side locking tool is held by the holding portion in the unlocked position. For this reason, for example, when the display unit is detached for maintenance or the like, there is no need for the operator to pull out the display unit while holding the operation unit in the unlocked state, thereby suppressing the complexity of the work. Can do.

  Particularly in this means, the display unit is moved to the front side of the gaming machine from the mounting completion position, that is, the unit side locking device is separated from the housing side locking device in the direction of detachment of the display unit. Since the holding of the tool is released, there is no need to separately release the holding state of the unit side locking tool. Thereby, complication of work can be suppressed and inconvenience that the display unit is not locked due to the operator forgetting to release the holding state can be avoided.

  Means 8. The unit-side locking tool is displaced toward the holding portion by an unlocking operation of the operation portion, and is elastically deformed by a reaction force caused by being pressed against the holding portion and is held by the holding portion. The gaming machine according to claim 7, further comprising a held portion (locking piece 621) that is in a state.

  According to the means 8, the unit side locking device has the held portion held by the holding portion of the housing side locking device. The held portion is displaced toward the holding portion by the operation of the operation portion. The unit side locking tool is elastically deformed by a reaction force caused by pressing the held portion against the holding portion, and the held portion is held by the holding portion. As a result, the held portion is held by the elastic deformation of the unit side locking device itself, and the held portion is held without using a biasing member and a mechanism for displacing the held portion, for example. it can. Therefore, it is possible to realize a practically preferable configuration without adding any components.

Means 9. A front door (front door 12) for closing and opening the opening of the housing;
An inner side door (inner door 700) provided on the rear side of the front door on the front side of the pattern display device and provided to be openable and closable on the unit body is provided, and the unit side locking tool is attached to the inner side door. The gaming machine according to any one of means 1 to 8, characterized in that it is provided on the back side.

  According to the means 9, the gaming machine is provided with a front door and an inner door in an inner and outer double, and the unit side locking device can be accessed by opening both the doors. In this case, it is difficult for the fraudster to have access to the unit side locking device (unlocking operation) because there is a restriction that both the inner and outer double doors must be opened so as to be inconspicuous as much as possible. It can be. On the other hand, when the display unit is taken out during regular work, both doors can be opened without restriction, so that the unit side locking tool can be easily accessed, and workability can be ensured. Become. By the way, no special operation is required to move both locking devices to the locked state, so even if the unit side locking device is provided on the back side of the inner door as described above, the workability is not complicated. Is possible.

  Further, as described in the means 7 or 8, the unit side locking tool may be configured to be held by the holding portion at a predetermined locking release position. In such a case, after both doors are opened and the unit-side locking tool is operated, it is possible to perform the drawing work with the inner door closed. As a result, inconveniences such as buffering or catching between the inner door and the front door at the time of pulling out the display unit are unlikely to occur, and the inner door can be protected and workability can be improved. .

  The inner door may have an opening or the like, and a part of the pattern display device may protrude forward from the opening or the like, and at least the center of gravity of the pattern display device may be behind the inner door. However, when the inner door has an opening or the like as described above, it is desirable that the operation unit overlaps the inner door in a front view of the gaming machine (that is, not visible from the front of the gaming machine).

Means 10. While making it the structure which supports the front door and the inner door so that rotation is possible,
The opening / closing base end portion of the front door and the opening / closing base end portion of the inner door are provided on both the left and right sides of the gaming machine, respectively, and the rotation directions when opening and closing each door body are opposite to each other. A gaming machine according to claim 9.

  According to the means 10, the front door and the inner door are configured such that the rotation directions are opposite to each other. For this reason, in order to access (reach) the unit-side locking tool (operation unit) provided on the back side of the inner door, it is necessary to open the front door greatly beyond a predetermined angle (for example, 90 degrees). . The act of opening the front door in such a way is easy to catch the eyes of the surroundings, making it difficult to access the unit-side locking tool by hiding the eyes of the monitor, and unauthorized release of the locked state of both locking devices Can be suppressed.

Means 11. A housing-side locking device that locks the front door in a closed position with respect to the housing; and a unit-side locking device that locks the inner door in a closed position with respect to the unit body.
The gaming machine according to means 9 or 10, wherein the unlocking states of both locking devices are independently performed.

  According to the means 11, since the locking device for locking the front door and the locking device for locking the inner door are independent from each other, it is possible to prevent the inner door from being opened as the front door is opened. Thereby, when the display unit is mounted, it is possible to perform work while the inner door is in the locked state in a state where the locked state of the front door is released and opened. Therefore, when the display unit is mounted, it is possible to suppress the inconvenience that the inner door is unexpectedly opened to contact other members such as the front door.

  Means 12. The gaming machine according to any one of means 1 to means 11, wherein the support member is constituted by a rail member (support rail 300) provided on left and right side plates (side plates 11d, 11e) of the housing.

  According to the means 12, the support member is provided separately on the left and right sides in the housing. Thereby, weight reduction as the whole gaming machine can be aimed at, ensuring the support function of a unit.

  Means 13. The gaming machine according to any one of means 1 to means 12, wherein the support member and the housing side locking tool are integrally formed.

  According to the means 13, by integrally forming the support member and the housing side locking tool, it is possible to reduce the number of parts and the assembly process. For example, sheet metal molding may be performed with a metal material such as aluminum.

  Here, in the means 3 (configuration in which the locking tool is provided at a plurality of locations), the positional deviation of the display unit can be suitably suppressed, but there is a concern that the number of parts increases. However, by combining with this means, it is possible to suitably suppress misalignment while suppressing an increase in the number of parts. In combination with the means 13 (the support member is constituted by left and right rail members), the rail member may be formed in a substantially U shape by bending both long sides of the long plate material to the same side, for example. By configuring the rail member to have a base plate portion and bent portions at both ends of the base plate portion, one of the two bent portions has a function of supporting the unit body, and the other is locked to the housing side. A function as a tool can be provided, and a practically preferable configuration can be realized while suppressing an increase in the number of parts.

  Here, “integral formation” means that the support member and the case side locking tool are integrally molded by resin molding or sheet metal molding, and the support member and the case side locking tool are integrated by welding or bonding, for example. Including

  Means 14. A braking section (surface contact section L2) that suppresses movement of the unit body in the mounting direction is provided on the back side of the section in which the display unit moves to the mounting completion position when the display unit is mounted on the housing. 14. A gaming machine according to any one of means 1 to means 13 characterized.

  According to the means 14, a braking section for suppressing movement of the unit main body in the mounting direction is provided on the back side of the section in which the display unit moves to the mounting completion position when the display unit is mounted on the housing. In this case, the unit body is braked in the braking section, which is the section where the attachment is completed, and the moving speed of the display unit is suppressed.

  Further, the unit-side locking tool is configured to lock when the display unit is moved to the mounting completion position. If the display unit is pushed into the housing vigorously, when the display unit moves to the mounting completion position, it will rebound and cause the inconvenience that the locking operation of the unit side locking device is not normally performed. I'm worried about it. However, in this means, since the moving speed of the display unit immediately before the completion of the mounting is suppressed, the locking operation of the unit-side locking tool can be made more reliable. Therefore, the transition to the locked state of both locking tools can be ensured.

  Means 15. When the display unit is mounted on the housing, a low frictional resistance is generated between the unit main body and the support member or other housing-side contact member that contacts the unit main body in a section where the display unit moves to the mounting completion position. A friction section (point contact section L1) and a high friction section (surface contact section L2) that generates a friction resistance larger than the friction resistance generated in the low friction section, the low friction section is on the near side, and the high friction section is on the front side. 14. The gaming machine according to any one of means 1 to means 13, wherein the gaming machine is provided on the back side.

  According to the means 15, when the unit main body is mounted on the housing, two sections (low friction section and high friction section) having different frictional resistances generated between the unit main body and the support member or the housing side contact member are provided. Is provided. In this case, the display unit can be moved more easily than the high friction section in the front side of the gaming machine, that is, in the low friction section, which is the section where the wearing starts. On the other hand, on the back side of the gaming machine, that is, in the high friction section, which is the end section of the game machine, the frictional resistance increases, so that the movement of the display unit is hindered, and the movement speed of the display unit is suppressed. If the display unit is pushed into the housing vigorously, when the display unit moves to the mounting completion position, it will rebound and cause the inconvenience that the locking operation of the unit side locking device is not normally performed. I'm worried about it. However, in this means, since the moving speed of the display unit immediately before the completion of the mounting is suppressed, the locking operation of the unit-side locking tool can be made more reliable. Therefore, the transition to the locked state of both locking tools can be ensured.

  Means 16. The gaming machine according to claim 15, wherein the low friction section and the high friction section are provided continuously.

  According to the means 16, the low friction section and the high friction section are continuously provided. By shifting from a state where the frictional resistance is small to a state where the frictional resistance is large, the frictional resistance can be increased rapidly at the boundary between them. Thereby, compared with the case where frictional resistance increases gently, the difference between both sections can be made clearer. In this case, when the display unit is pushed, when the display unit passes through the boundary between the low friction section and the high friction section, the display unit is close to the arrangement completion position and is in the section to be braked, that is, the locking. It is possible to suggest to the worker that the state will be shifted soon. Thereby, when the display unit is pushed in more strongly than necessary, the inconvenience that the transition to the locked state is hindered can be suppressed.

  According to the means 17, since the unit main body is in contact with the support member with the weight of the display unit, the braking force (friction resistance) can be obtained more effectively by using the weight of the display unit. Furthermore, since the braking force in the high friction section increases in proportion to the weight of the display unit, it is not necessary to separately adjust the braking force when replacing the model. That is, even when the weight of the display unit is changed, it is possible to obtain a braking force according to the change. Assuming that the display unit is braked by separately providing a buffer member (rubber, spring, etc.), the buffer member may need to be changed along with a change in the weight of the display unit. On the other hand, if braking is performed by frictional resistance using the weight of the display unit, it is not necessary to change the support member or the like in accordance with the replaced display unit. Therefore, the reusability of the braking member can be improved.

  Means 18.

  According to the means 20, the display unit in which the pattern display device is mounted on the unit main body is configured to be detachable from the housing, and provided on the housing side and the display unit side when the mounting is completed. Connectors are connected to each other. As a result, the housing side and the display unit side are electrically connected. For this reason, when the display unit is mounted, for example, a separate operation of connecting a harness provided on the display unit side and a harness provided on the housing side becomes unnecessary, and electrical connection can be easily performed. . Further, since the coupled connector is detached by removing the display unit from the housing, the electrical connection can be easily released.

  In addition, since the movement of the display unit from the mounting completion position is suppressed by both the locking devices on the housing side and the unit side, when the connectors are coupled, the position of the display unit is displaced, resulting in unstable connector coupling. It is possible to avoid the inconvenience of being released or released. For this reason, it is not necessary to fix the connectors so that they are not detached from each other, and the connector coupling structure can be simplified.

  In this means, at least one of the housing-side connector and the unit-side connector is a movable connector, and is attached so as to be movable in a direction orthogonal to the connector coupling direction by a connector support member. Specifically, the movable connector can be moved within a gap provided between the connector support member and the movable connector. Thus, when the display unit is mounted, the movable connector can be moved to a position where it can be coupled to the opposing connector, and the coupling position can be adjusted. For this reason, electrical connection, that is, position adjustment between the connectors when the housing side connector and the unit side connector are coupled can be facilitated. Further, since the movement of the movable connector in the connector coupling direction is restricted when the coupled connector is detached, both the connectors are easily separated by pulling out the unit body. Regarding the movement limitation of the movable connector in the connector coupling direction, the movable connector and the connector support member include a state in which the movable connector and the connector support member are always in contact in the connector coupling direction and there is no movable distance of the movable connector. Includes a state in which the movable connector has a slight clearance (rattle) in the connector coupling direction, and the movable connector is movable within the range of the clearance (rattle).

  As described above, the movable connector is configured to be movable within a gap provided between itself and the connector support member. For this reason, even when the display unit moves in an arbitrary direction, for example, up and down, left and right, etc. in a state where both connectors are coupled, the movable connector is moved in accordance with the movement of the display unit, and external force is concentrated on the connector. This can be suppressed. That is, it is possible to suppress the occurrence of deformation of the connector and cope with repeated use.

  According to the means 21, in the state where the shaft portion provided in one of the connector support member and the movable connector is inserted into the opening portion provided in the other, there is a gap between the inner surface of the opening portion and the shaft portion. The connector can be moved within the range where the inner surface of the opening is formed and abutted against the shaft. Thereby, the movement of the movable connector in a direction orthogonal to the connector coupling direction (hereinafter referred to as the alignment direction) can be suitably realized with a simple configuration.

  Further, in this means, the shaft portion and the opening portion are configured so as not to be directly related to the movement limitation in the coupling direction of the movable connector (corresponding to the external force generated in the coupling direction at the time of insertion / extraction), and the movement limitation in the coupling direction And the movement restriction in the alignment direction are independent of each other. For example, even if the movable connector is moved for alignment, the load for pulling out the connector is almost the same regardless of the moving position, and the load for pulling out the connector depends on the moving position of the movable connector. Inconvenient to increase. In other words, it is possible to reduce the load caused by the connector pulling-out operation with respect to the portion (shaft portion, opening) that restricts the movement of the connector in the alignment direction. Thereby, it becomes possible to suppress the influence on the movement adjustment site | part of the movable connector by the detachment | leave of a connector, and it can contribute to the durability improvement with respect to repeated use of a movable connector.

Means 22. One of the housing side connector and the unit side connector is a movable connector, the other is a fixed connector,
Means 21 or means 21, characterized in that a guide member (support member 819) is provided on the fixed connector side for guiding the movement of the movable connector to the coupling position when the unit body is attached to the housing. The gaming machine described.

  According to the means 22, one of the housing side connector and the unit side connector is fixed, and a guide member for guiding the movable connector to a predetermined coupling position is provided on the same side as the connector (fixed connector).

As a result, when the unit main body is mounted, the unit-side connector is pushed into contact with the upper surface of the guide member, whereby the vertical position of the unit-side connector is regulated and guided to a predetermined coupling position. That is, the guide coupling member can stabilize the coupling track of the connector, and the operation can be easily performed.

  In addition, by providing an inclined portion that is inclined downward at the front end portion of the upper surface of the guide member, the movable connector can be guided to the upper surface of the guide member along the inclined portion, thereby further improving workability. it can. In particular, the combination of means 3 (configuration in which the initial position of the movable connector is the lower limit of the movable range due to its own weight) and means 4 (configuration in which a support guide member for supporting and guiding the unit body is provided) is used as follows. The effect becomes. For example, by providing the inclined portion so as to correspond to the lower limit position of the movable range of the movable connector, the movable connector comes into contact with the inclined surface and is lifted upward as the unit body is pushed. Thereby, since the movement of the movable connector is guided by the guide member, the connector can be more easily and accurately coupled while suppressing the catch between the guide member and the movable connector. In addition, it is good for the protrusion direction of a guide member to be the same as the connection direction of a connector, or to incline below in the front-end | tip part by the side of a movable connector, ie, the direction inclined downward from the connector connection direction.

The locked state of the metal fittings 231 and 232 and the hook receiving portions 221 and 222 is released, and the locked state of the front door 12 with respect to the housing 11 is released.

  As shown in FIG. 8, in addition to the metal fittings 200 and 220, long plates 240 and 241 extending in the left and right directions are arranged along the upper and lower edges of the inner peripheral edge of the housing 11. . These plates 240 and 241 are respectively fixed to the top plate 11a and the bottom plate 11b by fasteners (not shown) such as screws. These plates 240 and 241, together with the metal fittings 200 and 220, have a function as a reinforcing material for the housing 11 and a function as a shielding material for the opening of the housing 11.

  The front ends of the plates 240 and 241 protrude from the opening edge of the housing 11 to the front of the slot machine 10, and the front ends of the metal fittings 200 and 220 also protrude to the front of the slot machine 10 across the entire opening edge. ing. That is, when the front door 12 is attached to the housing 11 with the front door 12 closed, the plates 240 and 241 and the metal fittings 200 and 220 face the opening edge of the housing 11 and the outer peripheral rear end of the front door 12. It is comprised so that the clearance gap between parts may be plugged from the inside. As described above, by arranging the metal fittings 200 and 220 and the plates 240 and 241, it is possible to prevent a wire, a film, or the like from entering the gap described above, and to prevent an illegal act.

  Further, bent portions 242 and 243 are formed at both left and right end portions of the plate 240 by being bent vertically so as to face the inside of the housing 11. These bent portions 242 and 243 are formed so as to overlap with the adjacent metal fittings 200 and 220 in the vertical direction in a side view of the slot machine 10 and on the front side of the opening edge of the housing 11. (The relationship between the bent portion 243 on the right side and the metal fitting 220 is shown in the partially enlarged view of FIG. As described above, the plate 240 and the metal fittings 200 and 220 are configured to overlap each other in front of the corner of the opening of the housing 11, so that a gap generated in the corner can be reduced. Thereby, it becomes possible to suppress the penetration | invasion of the wire, a film, etc. from those corner parts. Note that not only the plate 240 but also the plate 241 has the same configuration, so that it is possible to more appropriately prevent fraud.

  A partition plate 250 is horizontally mounted between the left side plate 11d and the right side plate 11e at a substantially central position in the height direction in the housing 11 (above the hopper device 110). The inside of the housing 11 is vertically divided by the plate 250. The space above the partition plate 250 is an installation area for the surface changing unit 400. The left and right end portions and the rear end portion of the partition plate 250 are respectively provided with bent portions (only the bent portion 251 formed at the rear end is shown in FIG. 8) bent at a right angle upward. . The partition plate 250 is attached to the housing 11 by fixing these left and right bent portions to the side plates 11d and 11e with fasteners (not shown) such as screws. In the present embodiment, the housing 11 is reinforced by providing the partition plate 250, but it is of course possible to reduce the weight by adopting a configuration in which the partition plate 250 is not provided.

(Description of support unit 260 and support rail 300)
In the left side plate 11d of the housing 11, a support unit 260 for mounting the surface changing unit 400 is fixed above the partition plate 250 (see FIGS. 8 and 9). The support unit 260 includes a metal spacer member 270 fixed to the left bent portion of the partition plate 250, and a metal support rail 300 that is attached to the spacer member 270 and supports and guides the surface changing unit 400. It has. In the right side plate 11 e of the housing 11, the right support rail 300 having the same height and the same configuration as the left support rail 300 is fixed above the partition plate 250.

  First, the configuration of the spacer member 270 will be described with reference to FIG. The spacer member 270 has a mounting portion 271 for mounting the support rail 300, and the mounting portion 271 has a substantially rectangular plate shape. A long hole 272 extending in the longitudinal direction of the mounting portion 271 is formed in the approximate center of the mounting portion 271. Further, flange portions 273 are formed at both ends in the short direction of the mounting portion 271 by being bent perpendicularly to the same side, and these flange portions 273 are provided with attachment portions 274 to the partition plate 250. The spacer member 270 is attached to the partition plate 250 by fixing the attachment portion 274 to the left bent portion of the partition plate 250 by a fixing means such as spot welding. In the present embodiment, the spacer member 270 is formed from a single iron plate material, but a light metal such as aluminum may be used or a synthetic resin material may be used.

  Next, the support rail 300 will be described. The support rail 300 is long like the spacer member 270, the left support rail 300 is attached to the spacer member 270, and the right support rail 300 is attached to the partition plate 250. Since the left and right support rails 300 have the same structure, the configuration of the left support rail 300 will be described below with reference to FIG.

  The support rail 300 has a base plate portion 310 for connecting to the mounting portion 271 of the spacer member 270, and the base plate portion 310 has a substantially rectangular plate shape. A guide piece 311 is provided at one end in the longitudinal direction of the base plate portion 310 by being bent at a right angle. In a state where the support rail 300 is attached to the housing 11 side, the bending tip end side of the guide piece 311 is outside the slot machine 10 with respect to the base plate portion 310, and the guide piece 311 is formed in the longitudinal direction of the base plate portion 310. This side is the front side in the slot machine 10. Hereinafter, in FIG. 11, the support rail 300 will be described on the assumption of these directions. A stopper piece 316 extending in the longitudinal direction of the base plate portion 310 at a right angle to the base plate portion 310 is formed at the end of the base plate portion 310 facing the side on which the guide piece 311 is provided. Yes.

  On the long side of the base plate portion 310, a lower guide portion 320 is formed by bending at right angles to the inside of the housing 11. The side where the lower guide part 320 is formed in the short direction of the base plate part 310 is the lower side in the slot machine 10 with the support rail 300 attached to the housing 11 side.

  The lower guide part 320 includes a horizontal part 321 that extends horizontally in the longitudinal direction of the base plate part 310, a front inclined part 322 that is formed to be inclined obliquely downward on the front side of the horizontal part 321, and a horizontal part 321. And a rear inclined portion 323 formed by being bent obliquely downward on the rear side.

  A resin piece 330 is disposed on the upper surface of the horizontal portion 321 with the boundary between the horizontal portion 321 and the front inclined portion 322 as the front end. The resin piece 330 is provided so as to protrude on the horizontal portion 321, and has a front inclined surface 331 inclined obliquely downward on the front side, a rear inclined surface 332 inclined obliquely downward on the rear side, and both inclined surfaces 331, 332. And a top portion 333 connecting the upper portions of the two. In the present embodiment, the top portion 333 is configured as a plane, but the configuration is not limited thereto, and the outer shape line may be configured to have a curved shape (R shape). The resin piece 330 constitutes a fall prevention means for preventing the face change unit 400 from dropping, and details thereof will be described later. Instead of the resin piece 330, the fall prevention means may be configured by bending the front portion of the support rail 300 to form a protruding portion. Thereby, the number of parts can be reduced.

  A bending member 340 formed in a substantially L shape is attached to the front part of the lower surface of the horizontal part 321. The bending member 340 has a flat plate-like attachment portion 341 for attachment to the horizontal portion 321, and a seat surface 342 that protrudes below the horizontal portion 321 and is orthogonal to the longitudinal direction of the horizontal portion 321. In addition, a tapered protrusion 343 is provided at substantially the center of the seating surface 342 so as to extend to the front side with respect to the longitudinal direction of the horizontal portion 321. In the present embodiment, the bending member 340 is provided separately, but the lower guide portion 320 may be formed by bending.

  On the rear side of the upper end of the base plate portion 310, an upper guide portion 350 is formed by being bent at a right angle so as to face the lower guide portion 320. The upper guide portion 350 is provided so as to extend horizontally in the front-rear direction similarly to the lower guide portion 320, and is divided forward and backward with a cut-and-raised 351 (notch 352) formed in the front portion as a boundary. ing. Reference numeral 350a denotes a divided front upper guide part 350, and reference numeral 350b denotes a divided rear upper guide part 350. A stopper 353 is formed on the upper portion of the cut and raised 351 by bending the upper end thereof inward, and an upright portion 354 that rises upward is formed on the inner end of the stopper 353. The upper guide portion 350 corresponds to a slide rail 510 (to be described later) on the surface changing unit 400 side, and has a lifting restraining function that suppresses the lifting of the surface changing unit 400 together with the slide rail 510. Further, the cut-and-raised 351 (notch 352) constitutes a locking means for locking the inner housing 410 to the housing 11 together with a later-described lever member 610 on the surface changing unit 400 side. 354 constitutes auxiliary means for assisting the unlocking operation together with the lever member 610. A detailed description of the upper guide portion 350 will be described later.

  The base plate portion 310 is fixed by fixing means such as bolting or spot welding in a state where the base plate portion 310 is in contact with the mounting portion 271 of the spacer member 270. Thereby, the support rail 300 is attached to the spacer member 270. A guide hole portion 312 extending in the longitudinal direction of the support rail 300 is formed in the approximate center of the base plate portion 310 of the support rail 300, and the long hole 272 of the spacer member 270 is formed correspondingly. ing. In other words, the guide hole portion 312 and the long hole 272 are penetrated by attaching the support rail 300 to the spacer member 270 in alignment. Details of the guide hole 312 will be described later.

(Relationship between spacer member 270 and metal fittings 200 and 220)
The spacer member 270 functions as a spacer that connects the bent portion on the left side of the partition plate 250 and the support rail 300 to be separated from each other. Here, the mutual relationship among the spacer member 270, each support rail 300, and the metal fittings 200 and 220 of the housing 11 will be described with reference to FIG.

  As described above, the left side plate 11d of the housing 11 is provided with the door support fitting 200 on the inside thereof. The offset amount W2 is offset by the spacer member 270 so that the offset amount W2 of the support rail 300 (specifically, the lower guide portion 320) from the left side plate 11d is larger than the protruding amount W1 of the door support metal fitting 200 from the left side plate 11d. Has been adjusted. Thereby, when the surface changing unit 400 described later is attached to or detached from the housing 11, it is possible to avoid the surface changing unit 400 from interfering with the door support fitting 200.

  On the other hand, the right side plate 11e of the housing 11 is provided with a hook receiving metal 220 inside thereof. The protrusion amount W3 of the hook receiving metal 220 from the right side plate 11e is sufficiently smaller than the width of the support rail 300 (the width of the lower guide portion 320). That is, even when the support rail 300 is attached to the right side plate 11e, the lower guide portion 320 for supporting the surface changing unit 400 projects inward from the flange receiving metal 220, and supports the surface changing unit 400. The width of the lower guide part 320 can be secured. Therefore, it is possible to avoid the same surface changing unit 400 from interfering with the hook receiving metal 220 when the surface changing unit 400 is attached or detached without using a spacer member. The protrusion amount W3 of the collar bracket 220 corresponds to an improvement in the rigidity of the opening of the casing 11, an improvement in the rigidity of the collar bracket 220 itself, an illegal act performed from a boundary portion between the casing 11 and the front door 12. It tends to be big. Thus, when the protrusion amount W3 becomes large and troubles in attaching and detaching the surface changing unit 400 occur, interference can be avoided by providing a spacer member on the right side plate 11e as well as the left support unit 260.

  As described above, since the attachment / detachment of the surface changing unit 400 is not hindered by the metal fittings 200, 220, it is not necessary to remove the metal fittings 200, 220 every time the surface changing unit 400 is attached, and the same surface changing unit 400. Can be efficiently attached and detached. Further, the offset of the support rail 300 is indispensable for the efficient attachment / detachment of the surface changing unit 400. However, if the offset amount W2 is increased meaninglessly, a disadvantage such as an increase in the dead space inside the housing 11 occurs. . Therefore, in the present embodiment, the internal space of the housing 11 is efficiently used by making the protrusion amount W1 and the offset amount W2 equal.

  8 and 9 again, the support rail 300 is formed at the lower end of the base plate portion 310 in addition to the long plate-like base plate portion 310 that is parallel to the side plates 11d and 11e and extends in the front-rear direction. The lower guide part 320 is formed by being bent vertically inward, and the upper guide part 350 is formed by being bent vertically inward at the upper end of the base plate part 310. Thus, by arranging the guide portions 320 and 350 side by side rather than side by side, the space in the left and right direction in the housing 11 can be used effectively. In the present embodiment, the guide portions 320 and 350 are formed by bending both ends of a single plate material to the same side, thereby reducing the number of components.

And an inner door 700 attached so as to be opened to the front side with the portion (the side opposite to the opening / closing axis of the front door 12) as an axis. In the present embodiment, the face change unit 400 is configured to include all the main parts that determine the game content of the slot machine 10, and if the model change is performed in a game hall or the like, this face change unit 400 The model can be changed by replacing the unit 400 with the new model. That is, the surface changing unit 400 constitutes an exchange unit at the time of model change. Each component will be described in detail below.

(Description of inner casing 410)
A configuration of the inner housing 410 will be described with reference to FIGS. 13 to 19 and 20. FIG. 20 is a perspective view showing the configuration of the inner housing 410. The inner housing 410 is integrally formed of a synthetic resin such as ABS. In this case, manufacturing is facilitated by making the inner housing 410 an integrally molded product made of resin. A metal door support fitting 740 is disposed on the right side of the front side edge of the inner housing 410 (on the side opposite to the door support fitting 200 of the front door 12), and a hook receiving bracket 750 is provided on the left side of the front edge. It is arranged. Further, elongated reinforcing plates 411 and 415 are disposed on both the upper and lower sides of the front edge, and the left and right ends of the reinforcing plates 411 and 415 are connected to the metal fittings 740 and 750. . In this way, the reinforcing plates 411 and 415 and the metal fittings 740 and 750 are connected to each other to form a frame shape and arranged around the opening edge of the inner housing 410 to improve the support rigidity of the inner door 700.

  The inner housing 410 includes a top plate portion 410a, a bottom plate portion 410b, a back plate portion 410c, a left side plate portion 410d, and a right side plate portion 410e, and is formed in a box shape with the front side opened as a whole. In addition to the synthetic resin, the inner housing 410 may be constituted by a wooden panel or a metal panel, or may be constituted by forming a single box using wood or a metal material. .

  As shown in FIG. 20, the front part of the top plate part 410a has double wall plates formed inside and outside, and a plurality of reinforcing ribs 420 are provided between the wall plates so as to connect the two. . The portion provided with the reinforcing rib 420 is a lattice-shaped reinforcing bar portion 421, and a through long hole 422 as a handle portion is formed at the center of the reinforcing bar portion 421. 13 to 19, the reinforcing plate 411 is fixed to the reinforcing bar portion 421 by a fastener such as a screw, and the reinforcing plate 411 has a central portion corresponding to the through long hole 422. Thus, a notch 412 is formed. The inner casing 410 (the surface changing unit 400) can be easily lifted by passing a finger through the through long hole 422. In addition, openings 423 penetrating inward and outward are formed at a plurality of locations (four locations in the figure) behind the reinforcing bar portion 421. Air can be discharged.

  A plurality of main ribs 425 extending in the attaching / detaching direction of the surface changing unit 400 and a plurality of sub ribs 426 extending intersecting the main ribs 425 are formed on the top plate portion 410a. An inclined surface 427 inclined obliquely downward is formed at the rear portion of the main rib 425. These ribs 425 and 426 have a function as a reinforcing portion that increases the rigidity of the top plate portion 410a. Other functions of the ribs 425 and 426 will be described later.

  The outer surface of the bottom plate portion 410b is formed in a substantially flat shape as a whole, and constitutes a placement portion for placing the surface change unit 400 on the ground or the like when transporting alone. In addition, in the state where the surface changing unit 400 is completely mounted in the housing 11, a part of the front side of the bottom plate portion 410 b protrudes forward with respect to the front end edge of the partition plate 250. The part 430 is provided with a horizontally long through-hole 431. Corresponding to the through long hole 431, the reinforcing plate 415 is also provided with a through long hole (not shown). By providing the through long hole 431 as described above, when attaching and detaching the surface changing unit 400, it is possible to easily perform the work by pushing and pulling the through long hole 431 with a finger.

  As shown in FIG. 20, on the inner surface of the bottom plate portion 410b, protrusions 435 extending in the front-rear direction along the side plate portions 410d and 410e are provided on the left and right.

Further, a screw hole 437 for screwing is provided at the center of the protrusion 436. FIG. 20 shows a left protrusion 435, a left protrusion 436, and a left screw hole 437.

  As can be seen in FIG. 17 (side view of the surface changing unit 400), the back plate portion 410c has a generally planar shape. The back plate portion 410 c is formed so as to be substantially parallel to the back plate 11 c of the housing 11 in a state where the surface changing unit 400 is completely mounted in the housing 11. For this reason, it is possible to suppress the occurrence of a dead space in the depth region of the housing 11 and to effectively use the depth region. Further, it is possible to suppress the installation of an illegal substrate or the like in the dead space.

  A step portion 440 that is recessed in a step shape is formed in the lower portion of the back plate portion 410c. Protrusions 441 that protrude rearward are provided on the left and right sides of the step portion 440. When the surface changing unit 400 is completely attached to the housing 11, the protrusions 441 come into contact with the bent portion 251 of the partition plate 250 (the back plate portion 410c and the back plate 11c do not interfere with each other). ), Positioning of the surface changing unit 400 in the depth direction is performed. That is, each protrusion 441 and the bent portion 251 constitute a depth direction positioning unit of the surface changing unit 400. In the present embodiment, the protrusion 441 is in contact with the bent portion 251. However, the protrusion 441 may be in contact with the back plate 11c.

  The surface changing unit 400 is mounted by placing a cushioning material having a small repulsive force such as urethane sponge or silicon pad on the outer surface of the back plate portion 410c of the inner housing 410 or the inner surface of the back plate 11c of the housing 11. It is possible to alleviate the collision between the protruding portion 441 and the bent portion 251 during the operation.

The guide piece 530 has a base portion 531 projecting outward, and the base portion 531 is fixed to the mounting plate portion 511 with a fastener such as a screw. An arm 532 extending rearward is formed on the rear outer side of the base portion 531. The base portion 531 and the arm 532 protrude so as not to interfere with the base plate portion 310 of the support rail 300 in a state where the inner housing 410 is mounted on the housing 11. A projection 533 protruding outward is formed at the rear end of the arm 532. More specifically, the protrusion 533 is formed so as to fit into the guide hole 312 of the support rail 300 in a state where the inner housing 410 is mounted on the housing 11.

  Further, the guide piece 530 is integrally formed of synthetic resin, and the arm 532 is configured to bend inward by receiving an external force from the outer side of the housing 11. In the present embodiment, on the back side of the protrusion 533, a support pin 534 protruding from the right side plate portion 410 e of the inner housing 410 is formed close to the back side of the protrusion 533. By these support pins 534, the amount of bending of the arm 532 is restricted so as not to be bent inward by a predetermined amount or more and to be plastically deformed.

  The resin piece 520 and the guide piece 530 together with the main rib 425 of the top plate portion 410a and the guide ribs 470 of the side plate portions 410d and 410e constitute the restricting means described above. In particular, with respect to the guide piece 530, in addition to the function as the restricting means described above, a drop-off preventing function for preventing the face-changing unit 400 from dropping out to the near side when the face-changing unit 400 is detached from the housing 11 is also provided. Have.

  A resin roller 540 is rotatably provided on the rear side of the rear end portion of the supported portion 512, that is, on the lower side of the rear portion of the right side plate portion 410e. More specifically, the roller 540 has a rotating shaft in a direction orthogonal to the right side plate 11e of the housing 11 and is pivotally supported with respect to the mounting plate portion 511 in a rotatable state. It protrudes slightly below the rail sliding surface 512a.

  The slide rail 510 and the roller 540 are provided corresponding to the support rail 300 on the housing 11 side. That is, when the surface changing unit 400 is mounted on the housing 11, the slide rail sliding surface 512 a of the slide rail 510 and the roller 540 are supported by the lower guide portion 320 of the support rail 300. . The slide rail 510 and the roller 540 constitute an attachment / detachment assist mechanism.

  The slide rail 510 is separately provided with a bending member 550 that protrudes below the supported portion 512. The bending member 550 is formed with an engagement hole 551 that can be engaged with the protrusion 343 of the support rail 300, and the engagement of the engagement hole 551 with the protrusion 343 causes the inner housing 410 (the surface changing unit 400 to be replaced). ) Is positioned.

  Since the engagement holes are provided in two different shapes (left and right sides in the present embodiment) in different shapes, these differences will be described (see FIG. 15). One engagement hole (the right engagement hole 551 in the present embodiment) of each engagement hole has a long hole shape extending in the vertical direction, and the inner casing 410 (surface) together with the right protrusion 343. It constitutes a left-right direction positioning means for positioning the replacement unit 400) in the left-right direction. On the other hand, the other engagement hole (in this embodiment, the engagement hole 553 provided in the left bending member 552) has a long hole shape extending in the left-right direction, and the left protrusion 343. At the same time, it constitutes vertical positioning means for positioning the inner casing 410 in the vertical direction. That is, the positioning means in the front-rear direction of the inner casing 410 and the left and right and upper and lower positioning means are configured independently of each other.

  The surface changing unit 400 tends to be heavy because it includes the reel device 650, the inner door 700, the main control device 770, and the like, and an impact caused by a collision at the time of mounting is applied to each positioning means, and deformation of the positioning means is caused. May cause problems. Therefore, in the present embodiment, the positioning means in the mounting direction (in the present embodiment, the front-rear direction) that is considered to be most susceptible to impact is constituted by the protrusion 441 and the back plate 11c (bent portion 251). Thus, the inner casing 410 and the casing 11 receive an impact at the time of mounting. As described above, since the front-rear direction positioning means is independent of the left-right and upper-lower positioning means, the load on the left-right and upper-lower positioning means can be reduced. Thereby, it becomes possible to maintain the positioning accuracy suitably.

  Next, the structure of the locking means for locking the inner casing 410 when the inner casing 410 is completely mounted will be described with reference to FIGS. 13 and 18. As the locking means, a lever member 610 having a substantially L shape in a side view provided rotatably on each of the side plate portions 410d and 410e, and an urging member for urging the lever member 610 in its rotational direction. And is configured. Since each lever member 610 and each biasing member have the same structure on the left and right, the right lever member 610 and the right biasing member will be described below with reference to FIGS. 21 and 22.

  A lever member 610 is attached to the front side of the right side plate portion 410e and above the right side mounting portion 464. That is, the right side plate portion 410 e is formed with a lever communication hole 611 that is a rectangular through hole corresponding to the lever member 610, and the lever member 610 is connected to the inside and outside of the inner housing 410 through the lever communication hole 611. It is in a state of communicating with. Under the lever communication hole 611, a bearing hole portion 612 is provided so as to penetrate inside and outside of the housing 11, and a support shaft 613 corresponding to the bearing hole portion 612 is formed in the lower portion of the lever member 610. Yes. A part of the support shaft 613 is configured to be exposed to the inside of the inner housing 410 in a state in which the support shaft 613 is fitted to the bearing portion 612. Is formed. The lever member 610 is attached by fixing the support shaft 613 to the right side plate portion 410e with a fastener such as a screw in a state where the support shaft 613 is fitted in the bearing hole portion 612. Since the support shaft 613 and the cylindrical portion 614 are provided so as to be rotatable relative to each other, the lever member 610 is rotatable with respect to the central axis of the support shaft 613. A substantially plate-like operation portion 615 extending upward is formed on the upper side of the bearing hole portion 612. The lower portion of the operation portion 615 exposed to the outside of the inner housing 410 extends rearward perpendicular to the operation portion 615. An arm 616 is provided. At the tip of the arm 616, a hook part 617 is formed that protrudes downward so as to be able to be locked with the notch 352 of the support rail 300, and the lever member is formed by pressing the operation part 615 toward the front side of the slot machine 10. 610 rotates with the central axis of the support shaft 613 as a reference, and the flange portion 617 moves upward.

  A projecting portion 618 projecting rearward is formed on the rear surface side of the operation unit 615, and the projecting portion 618 is in contact with the inner wall of the lever communication hole 611. That is, the lever member 610 is rotatable in a range from the state where the overhanging portion 618 is in contact with the inner wall of the lever communication hole 611 to the time when the front end portion of the lever member 610 is in contact with the lever communication hole 611. .

  A guide surface 619 that is inclined obliquely upward is formed on the rear side of the flange portion 617, and the guide surface 619 allows the flange portion 617 to be attached to the upper guide portion 350 of the support rail 300 when the inner housing 410 is mounted. (Details are notched 352). Further, a hook portion 620 that protrudes outward is formed at the rear end portion of the outer surface of the arm 616, and a guide surface 621 that is inclined downward toward the outer side is provided at the upper portion of the hook portion 620. Yes. A constricted portion 622 that extends vertically is formed at the front portion of the outer surface of the arm 616. By applying an external force to the rear side of the arm 616, for example, the hooking portion 620 from the side toward the inside, the arm 616 is configured to bend inward with respect to the constricted portion 622.

  Next, a biasing member that biases the lever member 610 in a predetermined rotation direction will be described. A leaf spring 631 as an urging member is provided on the rear side of the lever member 610. The leaf spring 631 has a long shape extending horizontally, and is fixed to the right side plate portion 410e by a fastener such as a screw. The front end of the leaf spring 631 is in contact with an action portion (not shown) provided on the lever member 610 from above. Thereby, the lever member 610 has a configuration in which the flange portion 617 is constantly urged downward. In the present embodiment, the plate spring 631 is used as the urging member. However, by using a coil spring instead of the plate spring 631, the flange portion 617 may be constantly urged downward. Good. Further, the locking means (the lever member 610 and the urging member) are provided on both the left and right sides, but the present invention is not limited to this.

  Attaching / detaching assist mechanism including the slide rail 510 and the roller 540, a restricting means such as the guide piece 530, and a locking means including the lever member 610 provided on the side plate portions 410d and 410e of the inner casing 410. Is configured not to protrude downward from the bottom plate portion 410b of the inner casing 410. That is, the outer surface of the bottom plate portion 410b of the inner housing 410 is configured to be the lowermost portion. When the inner housing 410 (replacement unit 400) is placed on the floor or the like when the unit is replaced, the outer surface (the mounting portion described above) of the bottom plate portion 410b comes into contact with the floor or the like. As a result, even when the inner casing 410 is inadvertently placed on the floor or the like, the attachment / detachment assist mechanism, the regulating means and the locking means provided in the side plate portions 410d and 410e are deformed or damaged. Problems can be prevented, and the inner housing 410 can be prevented from moving unexpectedly due to the roller 540 rolling.

(Description of attaching / detaching operation of the inner casing 410)
The attaching / detaching work of the inner casing 410 (the surface changing unit 400) will be described with reference to FIGS. FIG. 23 is a partial schematic view showing a state of assembling the inner casing 410 in a state where the inner casing 410 is viewed from the side, and FIG. 24 shows a state in which the inner casing 410 is completely attached to the casing 11. FIG. FIG. 23A shows a state where the roller 540 of the inner casing 410 is placed on the support rail 300, and FIG. 23B shows a moving state of the inner casing 410 accompanied by the rotation of the roller 540. 23 (c) shows a state in which the inner housing 410 is completely attached to the support rail 300. When the inner casing 410 is mounted, the work is performed in the order of FIG. 23 (a) → FIG. 23 (b) → FIG. 23 (c).

  In the present embodiment, the friction resistance between the inner casing 410 and the support rail 300 in contact with the inner casing 410 during the section in which the inner casing 410 moves to the mounting completion position when the inner casing 410 is mounted on the casing 11. And a high friction section in which a friction resistance greater than the friction resistance generated in the low friction section is provided such that the low friction section is on the near side and the high friction section is on the back side. In particular, the support rail 300 and the roller 540 are in point contact in the low friction section, and the support rail 300 and the slide rail 510 are in surface contact in the high friction section. Thus, by providing the low friction section (point contact section L1) and the high friction section (surface contact section L2), the detachability of the inner casing 410 is improved and the slot machine 10, particularly the inner casing 410 and the like. It is possible to protect. The details will be described below.

  Here, “point contact” means that when the surface changing unit 400 (inner housing 410) moves, the contact portion in the unit moving direction is point-like. When a rotating body such as a roller is used as the contact member, the rotating body has a width in a direction orthogonal to the unit movement direction (that is, the same direction as the rotation axis), and therefore in a direction orthogonal to the unit movement direction. Although the contact may be linear, if the contact portion in the unit moving direction is a point, this is also included in the “point contact”. In addition, for example, when the rotating body comes into contact with the plate surface, it is assumed that the contact portion of the rotating body expands due to force such as weight, but in this way, when the contact portion of the rotating body expands due to force such as weight, It is included in “point contact”.

  As shown in FIG. 23A, when the inner casing 410 (replacement unit 400) is mounted, the roller 540 is placed on the horizontal portion 321 of the support rail 300, and the inner casing 410 is lifted to raise the inside of the casing 11. Push into. In the present embodiment, by providing the front inclined portion 322 of the support rail 300 and the resin piece 330 having the front inclined surface 331, the front inclined portion 322 even when the lifting height is slightly low at the time of mounting. Alternatively, the roller 540 is guided to the horizontal portion 321 of the support rail 300 while being in contact with the front inclined surface 331, so that the roller 540 can be prevented from being caught on the support rail 300 and smoothly mounted. Further, when the inner casing 410 unexpectedly rolls forward in a state where the roller 540 is placed on the upper surface of the horizontal portion 321 (hereinafter referred to as a contact surface 321a) beyond the resin piece 330, the resin piece 330 Since the roller 540 is caught by the rear inclined surface 332, the inconvenience that the inner casing 410 is unintentionally dropped from the casing 11 hardly occurs. When removing the inner casing 410, the roller 540 hits the resin piece 330 by pulling the inner casing 410 toward the near side, and the roller 540 is at the front end of the lower guide portion 320, that is, the inner casing 410. It is possible to suggest to the operator that the state is immediately before being detached from the housing 11.

  Next, as shown in FIG. 23 (b), in a state where the roller 540 is placed on the contact surface 321a beyond the resin piece 330, the supported portion 512 of the inner housing 410 slides on the slide rail. The surface 512 a is supported by the resin piece 330 in a state where the surface 512 a is in contact with the resin piece 330, and the roller 540 of the inner housing 410 is supported by the horizontal portion 321. That is, the inner casing 410 is supported by the support unit 260 of the casing 11 at a total of four points, two on each side, so that the weight of the inner casing 410 is quickly and stably moved to the casing 11 side. You can deposit. Further, since it is supported at four points in this way (hereinafter, a state where it is supported at four points is referred to as a point contact state), the inner casing with respect to the contact surface 321a of the horizontal portion 321 of the support rail 300 included in the casing 11 is used. The slide rail sliding surface 512a of the slide rail 510 included in the body 410 is in a state of floating in a non-contact manner. When the inner casing 410 is moved in the front-rear direction, the roller 540 rolls on the contact surface 321a and the slide rail sliding surface 512a slides while contacting the resin piece 330, so that an appropriate frictional resistance is given. However, the inner casing 410 can be moved forward and backward.

  The resin piece 330 has not only a function as a fall prevention unit for the inner casing 410 (replacement unit 400) described above, but also a function as a resistance reduction means for reducing the frictional resistance when the inner casing 410 is moved. Have. If attention is paid to this point, when the protrusion is formed by bending the front end of the support rail 300 to replace the resin piece 330, it is desirable to coat the protrusion with a fluororesin having a low frictional resistance. .

  In the present embodiment, the amount of protrusion of the top portion 333 formed on the resin piece 330 from the support rail 300 is made equal to the amount of protrusion of the roller 540 from the slide rail sliding surface 512a, so that the slide rail sliding surface. 512a and contact surface 321a are substantially parallel. Here, for example, when the height of the resin piece 330 is made larger than the same, the front portion of the slide rail sliding surface 512a is lifted so that the rear portion of the inner housing 410 is tilted so as to be lowered. It becomes possible to move the housing 11 to the back side more easily with the self-weight effect of 410.

(Explanation of roller drop and friction deceleration)
When the roller 540 reaches the rear inclined surface 332 of the support rail 300, the roller 540 is guided by the rear inclined portion 323 and separated from the lower guide portion 320. The unit-side pitch between the central axis of the roller 540 and the lower end of the guide portion 513 in the attaching / detaching direction of the surface changing unit 400 is relative to the housing-side pitch between the upper end of the rear inclined surface 332 and the upper end of the rear inclined portion 323. Are almost equivalent. For this reason, the guide portion 513 is guided to the rear inclined surface 332 of the resin piece 330 almost in synchronization with the separation of the roller 540. That is, the point contact state shown in FIG. 23B is shifted to a surface contact state in which the slide rail sliding surface 512a and the contact surface 321a are in surface contact. Note that L1 shown in FIG. 23 is a point contact section in which the inner housing 410 is moved in a point contact state, and L2 is a surface contact section in which the inner housing 410 is moved in a surface contact state. Incidentally, when the rear inclined portion 323 is not provided, the inner housing 410 suddenly falls and receives an impact when switching between L1 and L2, but according to the configuration of the present embodiment, the inner housing 410 Since it moves obliquely downward along the rear inclined portion 323, there is no inconvenience such as receiving an impact.

  In the above-described surface contact state, the function of the roller 540 is deactivated, and slipping by the resin piece 330 is not used, so that a larger frictional resistance is generated than in the point contact state. As a result, even when the inner casing 410 is pushed into the back side of the casing 11 in a point contact state with little frictional resistance, the frictional resistance increases when the surface casing is shifted to the inner casing 410. 23 (c), the inner side until reaching the mounting completion position (the position where the protrusion 441 of the inner housing 410 abuts against the bent part 251 of the partition plate 250). The momentum of the housing 410 can be reduced. By doing so, it is possible to suppress problems such as the inner housing 410 colliding with the back plate 11c of the housing 11 vigorously and the slot machine 10 being damaged.

  Next, the removal work of the inner housing 410 will be described. When the inner housing 410 is removed, the work is performed in the order of FIG. 23 (c) → FIG. 23 (b) → FIG. The roller 540 is lifted up to the contact surface 321a along the rear inclined portion 323 by pulling the inner casing 410 toward the front side from the mounting completion state shown in FIG. 23C, and the guide portion 513 is inclined rearward of the resin piece 330. It is lifted along the surface 332 to the top 333. At this time, since the roller 540 is guided by the rear inclined portion 323 and the guide portion 513 is also guided by the rear inclined surface 332, it can be drawn relatively easily. Further, by pulling further toward the front side, the roller 540 gets over the resin piece 330 as described above, and the separation of the inner casing 410 is completed (see FIG. 23A). In addition, the inner casing 410 can be slipped better by using a material having a low frictional resistance on the contact surface between the support rail 300 and the slide rail 510 or by coating the contact surface with a fluororesin having a low frictional resistance. In addition, the inner casing 410 can be pushed or pulled more easily.

(Explanation of operation of restriction means)
The operation of the restricting means for restricting the attaching / detaching direction of the inner housing 410 when the inner housing 410 is attached / detached will be described. As shown in FIG. 23A, when the inner casing 410 (replacement unit 400) is mounted, the roller 540 is placed on the contact surface 321a of the support rail 300, and the inner casing 410 is lifted to move into the casing 11. Push into. When the inner casing 410 is pushed forward and backward with respect to the casing 11 as described above, the main rib 425 of the inner casing 410 contacts the lower surface of the top plate 11a of the casing 11 and It moves so that the main rib 425 slides on the lower surface of the plate 11a. Thereby, the inconvenience that the inner housing 410 is inserted into the housing 11 at an angle is regulated.

  Further, as described above, the first box 480 of the housing 11 and the left and right guide ribs 470 are provided close to each other. For this reason, when the inner casing 410 is pushed into the casing 11 while being tilted left and right, the first box 480 and the guide rib 470 come into contact with each other, so that the tilt is reduced below the inner casing 410. Can be suppressed. When the inner casing 410 is further pushed into the inner side of the casing 11, the second box 490 and the guide rib 470 come into contact with each other, so that the inner casing 410 is tilted to the left and right. It is suppressed on the upper side. Thus, by providing the restricting means (boxes 480, 490 and guide rib 470) at a low position in the front and a high position in the rear, at the initial stage of mounting, on the lower side with a small deviation and at the completion of mounting. Can be regulated on the upper side, which can effectively suppress the deviation. Furthermore, by restricting in four places in this way, the rotation and twisting of the inner housing 410 to the left and right can be effectively suppressed, so that an unexpected shift after completion of mounting can also be suppressed.

  That is, these ribs 425 and 470 have not only a function as a reinforcing part that increases the rigidity of each of the plate parts 410a, 410d, and 410e but also a function of restricting displacement when the surface changing unit 400 is attached to the housing 11. Yes.

  In addition, since the main rib 425 is provided with the inclined surface 427, when the inner housing | casing 410 is pushed in, the main rib 425 will be hooked on the front-end edge of the top plate 11a, and the malfunction that obstructs pushing operation does not arise. Further, since the protruding amount of the secondary rib 426 is smaller than that of the main rib 425, the pushing operation is not hindered. Similarly, since each guide rib 470 is also provided with the inclined surface 471, when the inner housing 410 is pushed in, the guide rib 470 is caught on the boxes 480 and 490, so that the pushing operation is not hindered. Moreover, since the protrusion amount of the auxiliary rib 472 is also smaller than that of the guide rib 470, the pushing operation is not hindered.

  As shown in FIG. 23B, when the inner casing 410 reaches a predetermined position in a state where the inner casing 410 is supported by the support rail 300 at four points, the resin piece 520 of the slide rail 510 is obtained. Is configured to be close to the lower surface of the upper guide portion 350 of the support rail 300. That is, the amount of protrusion of the contact portion 521 formed on the resin piece 520 from the holding portion 515 is such that the distance in the vertical direction from the lower end of the roller 540 to the contact portion 521 is the parallel guide portions of the support rail 300. It is provided to be slightly smaller than the distance of 320,350. Thereby, it is possible to restrict the inner casing 410 from rotating with the resin piece 330 as a reference, and the rear portion of the inner casing 410 from being lifted upward. In the present embodiment, when the inner casing 410 is shifted to the surface contact state, the resin piece 520 is separated from the upper guide portion 350 as the roller 540 is detached from the lower guide portion 320. It is the composition to do. Of course, it is possible to make this vertical restriction effective until the mounting is completed by forming an inclined part and a step part along the movement of the resin piece 520 at the rear part of the upper guide part 350.

  In the present embodiment, in addition to the restricting means, one of the features is that the guide piece 530 and the guide hole portion 312 are provided and a guide means for restricting a small deviation is provided. That is, the inner casing 410 whose attachment / detachment direction is restricted by the restriction means is guided to a predetermined position by the guide means. Hereinafter, a specific operation of the guide means will be described.

  When the inner housing 410 (the surface changing unit 400) is placed on the support rail 300 and pushed to a predetermined position, the protrusion 533 of the guide piece 530 comes into contact with the guide piece 311 of the support rail 300. By further pressing, the protrusion 533 is guided onto the inner surface of the base plate portion 310 by the guide piece 311 and the arm 532 is bent inward. That is, the arm 532 is biased toward the base plate portion 310.

  When the inner casing 410 is moved further back and the projection 533 of the arm 532 reaches the guide hole 312, the arm 532 tries to restore the original shape by the elastic force, so that the projection 533 is guided. It fits into the hole 312. As the inner casing 410 further moves to the back side, the projection 533 also slides in the guide hole portion 312 to the back side. The guide hole 312 includes a front horizontal hole 313 provided on the front side, a rear horizontal hole 314 provided below and behind the front horizontal hole 313, and an inclined hole 315 connecting them. These hole portions 313 to 315 are respectively provided corresponding to the moving direction of the roller 540. That is, in a state where the protrusion 533 exists in the front horizontal hole 313, the roller 540 is on the horizontal portion 321, and in a state where the protrusion 533 exists in the inclined hole 315 (point contact state), the roller 540 moves backward. In a state (surface contact state) where the protrusion 533 exists on the inclined portion 323 and the protrusion 533 exists in the rear horizontal hole portion 314, the roller 540 is separated from the lower guide portion 320. In addition, it is desirable that the gradient of the inclined hole portion 315 is equal to the gradient of the rear inclined portion 323. By doing so, the movement of the roller 540 and the movement of the guide piece 530 can be synchronized even when the roller 540 is rolling on the rear inclined portion 323.

  As described above, when the inner casing 410 is pushed or pulled out, the projection 533 moves with the guide hole portion 312 fitted in accordance with the movement of the inner casing 410, so that the direction of the pushing or pulling out is performed. Therefore, the vertical displacement is less likely to occur. That is, when the inner housing 410 is attached or detached, it is not necessary for the operator to adjust the push-in or pull-out direction, and the complication of work can be suitably suppressed. Furthermore, since the regulating means and the guiding means are provided independently, a large deviation can be regulated by the regulating means, and a small deviation can be regulated by the guiding means. It can guide to a predetermined position (mounting position) without doing.

  In addition, the guide piece 530 has a function of preventing falling out as described above. The dropout prevention function will be described in detail with reference to FIGS. 11 and 22. Referring to FIG. 11, the front end of the guide hole portion 312 of the support rail 300 has an inclined surface 318 that is inclined toward the right side plate 11 e of the housing 11 (that is, in a direction away from the inner housing 410). (Only the lower inclined surface 318 is shown in the figure). As shown in FIG. 22, a hook portion 535 corresponding to the front end edge of the guide hole portion 312 is formed at the front portion of the protrusion 533 of the guide piece 530. The hook portion 535 has a wall shape standing substantially perpendicular to the outer side of the inner housing 410 from the arm 532 and can be locked to the front end edge of the guide hole portion 312.

  When the inner casing 410 (the surface changing unit 400) is detached, the inner casing 410 is moved in a state where the projection 533 of the guide piece 530 is accommodated in the guide hole portion 312 of the support rail 300, and the inner casing 410 is predetermined. When the guide piece 530 is pulled out, the hook portion 535 of the guide piece 530 comes into contact with the front end edge of the guide hole portion 312 and the further movement of the inner casing 410 is restricted.

  As described above, before the inner casing 410 is completely pulled out from the casing 11, the movement of the inner casing 410 is restricted, and the drawer is temporarily restricted, so that the inner casing 410 is unexpectedly dropped out. Can be avoided. By restricting the movement of the inner casing 410, it is possible to notify the worker that the inner casing 410 can be detached, and the inner casing 410 (specifically, the roller 540) is supported by the support rail 300. The drawing operation can be performed even if the operator does not visually confirm the position of the contact surface 321a (specifically, the contact surface 321a).

  When the movement of the inner casing 410 is restricted when the inner casing 410 is pulled out, the projection of the guide piece 530 is first performed by tilting the inner casing 410 backward at a predetermined angle (about 10 ° in the present embodiment) or more. The protrusion 533 is moved upward along the inclined surface 318 while the arm 532 is bent toward the inside of the housing 11, and the protrusion 533 is detached from the guide hole portion 312. Thereby, the movement restriction of the inner casing 410 is released, and the inner casing 410 can be further pulled out. When the inner casing 410 is detached, the movement of the inner casing 410 is temporarily stopped as described above without visually checking whether the inner casing 410 is placed on the support rail 300. Thus, the operator can easily recognize that the inner casing 410 is about to be detached. Therefore, when the inner casing 410 is detached, it is possible to prevent the weight burden of the inner casing 410 from being transferred to the worker in an unintended state by the worker, and to prevent the inner casing 410 from falling off.

(Description of operation of locking means)
The operation of the locking means will be described with reference to FIGS. 23C and 25 again. When the inner housing 410 (the surface changing unit 400) is pushed into the back side of the housing 11 along the support rail 300, the point contact state is changed to the surface contact state as described above. After the transition to the surface contact state, by continuing the pushing operation, the flange portion 617 of the lever member 610 comes into contact with the front end of the upper guide portion 350. In accordance with the pushing operation, the collar portion 617 is lifted upward along the guide surface 619 against the urging by the leaf spring 631 and is placed on the upper guide portion 350. Then, in synchronization with the positioning of the inner housing 410 in the front-rear direction, the flange 617 is fitted into the notch 352, and the same flange 617 is locked to the front edge of the notch 352. In other words, the inner casing 410 is in a state in which forward movement is restricted.

  In a state where the flange portion 617 is locked to the notch 352, the operation portion 615 of the lever member 610 is tilted forward against the biasing force by the leaf spring 631, so that the center axis of the support shaft 613 is used as a reference. Since the lever member 610 rotates, the flange 617 is separated from the notch 352.

  Here, the guide surface 621 is formed so that the center thereof corresponds to the lower end of the upright portion 354 of the raised portion 351. In other words, the center of the guide surface 621 of the arm 616 contacts the lower end of the upright portion 354 by the rotation of the lever member 610. By further tilting the operation portion 615 forward, the hook portion 620 is guided on the side surface of the standing portion 354 by the guide surface 621. In other words, the arm 616 is lifted upward in a state where the arm 616 is urged toward the upright portion 354 by bending inward. When the hook portion 620 moves to above the upper end of the upright portion 354, the hook portion 620 is locked to the upper end edge of the upright portion 354 as the bending of the arm 616 is restored to the original state. The Thereby, the hook part 620 is hold | maintained by the standing part 354, and the lever member 610 is maintained in the state which performed fall-down operation (refer FIG. 25). That is, after the operation unit 615 is pushed down, it is not necessary to keep the operation unit 615 continuously, and it is possible to avoid complication of work such as pulling out the inner casing 410 while pressing the operation unit 615. be able to. In addition, after the lever member 610 is tilted down, the inner casing 410 is pulled toward the front side, so that the hook portion 620 is slidably moved on the upright portion 354 and separated from the upper guide portion 350.

  With reference to FIG. 24 again, a state in which the inner housing 410 is completely attached to the housing 11 will be described.

  On the back side of the housing 11, the stopper piece 316 of the support rail 300 is inserted into the insertion portion 517 of the slide rail 510. In the surface contact state, the stopper piece 316 is inserted into the insertion portion 517 as the inner casing 410 is further pushed into the inner side of the casing 11 to be in the above state. Thereby, when the rear part of the inner side housing | casing 410 moves up and down unexpectedly, the stopper piece 316 contact | abuts to the insertion part 517, and this movement is suppressed. On the other hand, on the front side of the housing 11, the protrusions 343 of the support rail 300 are engaged with the engagement holes 551 and 553 of the slide rail 510, so that the movement in the vertical and horizontal directions is restricted. As described above, by providing a plurality of movement restrictions in the mounting completion state, the unexpected movement of the inner housing 410 can be suitably suppressed without using fixing means such as fasteners.

  As described above, since these ribs 425 and 426 are formed close to the top plate 11a of the housing 11, an unauthorized board is installed between the inner housing 410 and the top plate 11a of the housing 11. Space that can be reduced. In addition, since the guide rib 470 and the boxes 480 and 490 are also arranged close to each other, it is possible to reduce a space in which an unauthorized board can be installed between the inner casing 410 and the side plates 11d and 11e of the casing 11. . That is, it can be said that the ribs 425, 426, 470, 472 and the boxes 480, 490 constitute an illegal board installation preventing means. It should be noted that in order to more effectively prevent the installation of an illegal base, it is natural to increase the number of ribs 425, 426, 470, 472, increase the number of boxes 480, 490, or increase the size. Is possible.

  Next, the configuration of the reel device 650 will be described with reference to FIG. 19 (an exploded perspective view of the surface changing unit 400). The reel device 650 includes a synthetic resin case member 651 opened to the front, and synthetic resin reel plates 652 to 654 (left reel plate 652, middle reel plate 653, and right reel plate) accommodated in the case member 651. 654) and three reels 655 to 657 (left reel 655, middle reel 656, and right reel 657) of left, middle, and right attached to each of the reel plates 652 to 654.

  In the case member 651, a support fixing portion 658 protruding outward is provided at the front upper corners of both side surfaces, and a mounting hole 659 penetrating in the front-rear direction is formed in the approximate center of the front surface of the support fixing portion 658. Has been. Further, in the case member 651, a support fixing portion 660 that protrudes outward is provided at the front lower corners of both side surfaces, and a mounting hole 661 that penetrates in the front-rear direction is formed at the approximate center of the front surface. Yes. These attachment holes 659 and 661 constitute attachment means for attaching the reel device 650 to the inner casing 410.

  These mounting holes 659 and 661 are formed corresponding to the protrusions 436 and 475 of the inner housing 410. The reel device 650 is fixed inside the inner housing 410 by screwing screws into the screw holes 437 and 476 of the protrusions 436 and 475 with the protrusions 436 and 475 fitted in the mounting holes 659 and 661. It has become.

  Since the configuration of each of the reels 655 to 657 is well known, detailed illustration is omitted here, and the configuration will be briefly described. Each of the reels 655 to 657 includes a cylindrical skeleton member that forms a cylindrical cage, and a belt-like belt wound around the outer periphery thereof. On the outer peripheral surface of the belt, a number of symbols as identification information are printed at equal intervals (for example, 21 symbols). At the center of each reel 655 to 657, a stepping motor as a drive source is provided, and each reel 655 to 657 is rotated individually by driving the stepping motor, that is, independently.

  The reel plates 652 to 654 have a plate shape that stands vertically and extends back and forth, and the stepping motor described above is fixed to the approximate center of the reel plates 652 to 654. The reels 655 to 657 are rotatably supported on the right side of the reel plates 652 to 654. In addition, when the upper and lower ends of the reel plates 652 to 654 are fixed to the case member 651 by screws or the like, a part of each reel 655 to 657 appears from the front opening portion of the case member 651. . The front side portions of the reel plates 652 to 654 are configured in a shape corresponding to the exposed portions of the reels 655 to 657 from the case member 651.

  Further, a plate-shaped shielding member 662 formed so as to block the exposed portion of the right reel 657 from the right side is fixed to the right edge of the front opening portion of the case member 651 by a fastener such as a screw.

  The reel device 650 is provided with a reel index sensor (rotation position detection sensor) for detecting the rotation position of each of the reels 655 to 657 as another configuration. Further, a backlight (rear light emitting means) made of a fluorescent lamp or the like is provided on the inner peripheral side of each reel 655 to 657. By this backlight, each symbol attached to the outer peripheral surface of the reel is brighter than the rear. Illuminated. By the light emission of the backlight, it is possible to improve the visibility of each symbol attached to the outer peripheral surface of the reel and to diversify the auxiliary effects in the game.

  In the present embodiment, the reel plates 652 to 654 and the shielding member 662 can prevent the inside of the case member 651 from being seen from the outside. That is, the light from the backlight can be prevented from leaking outside the reel device.

(Description of inner door 700)
The configuration of the inner door 700 will be described in detail with reference to FIGS. 18 and 19 again. The inner door 700 includes a base 710 made of synthetic resin, a liquid crystal display device 711 as an auxiliary effect device, a front frame 720 provided so as to surround an edge on the front side of the liquid crystal display device 711, and a main control device. A display control device 730 that performs subordinate display control based on a command from 770, a bearing fitting 745 for attaching the inner door 700 to the inner casing 410, and the inner door 700 is closed with respect to the inner casing 410. And a door lock fitting 760 for holding in the state.

  The base 710 has a substantially square shape when viewed from the front, and a panel support portion (not shown) protruding forward is formed along the outer peripheral edge of the base 710 at the upper and lower portions of the front surface. The liquid crystal display device 711 includes a liquid crystal panel and a liquid crystal driver that drives the liquid crystal panel, and, like the base 710, has a substantially square shape when viewed from the front. The liquid crystal display device 711 is formed corresponding to the base 710 and is mounted on the base 710 by being sandwiched between the upper and lower sides by a panel support portion. Further, attachment portions are formed at the four corners of the liquid crystal display device, and these attachment portions are fixed to the base 710 with fasteners such as screws.

  Further, a front frame 720 made of synthetic resin is disposed on the front side of the liquid crystal display device 711 so as to surround the liquid crystal display device 711, and the front frame 720 is disposed between the front frame 720 and the base 710. The liquid crystal display device 711 is sandwiched between the base 710 and a fastener such as a screw. The front frame 720 is formed in a substantially square shape as a whole, and a shielding portion 721 extending upward of the liquid crystal display device 711 is provided on the upper portion of the front frame 720.

  A display window 723 having a horizontally long rectangular shape is provided at the lower center of the liquid crystal display device 711, and a display window 724 corresponding to the display window 723 is also provided on the base 710. As a result, in a state where the liquid crystal display device 711 is mounted on the base 710 and the inner door 700 is closed to the inner housing 410, the reel device disposed inside the inner housing 410 via both display windows 723 and 724. 650 reel symbols are visible. In the present embodiment, the display window 723 is made of a transparent resin without a liquid crystal display, but may be made of a through-hole penetrating in the front-rear direction.

  The display control device 730 includes a display control board (not shown) on which electronic components such as a CPU and a memory are mounted, and a substantially rectangular parallelepiped case member (case base 733 and case cover 734) for housing the display control board. It is composed of The case base 733 and the case cover 734 are formed of a transparent synthetic resin material, and the display control board inside the case base 733 and the case cover 734 is visible. The case base 733 is provided with two attachment portions for attachment to the base 710, and the display control device 730 is attached to the upper back of the base 710 via the case base 733.

  Next, a specific configuration of the assembly structure of the inner door 700 and the inner casing 410 will be described.

  The inner door 700 is supported by the door support fitting 740 provided in the inner housing 410 so as to be opened and closed. As shown in FIG. 17, the door support fitting 740 has a long shape, is assembled to an attachment base 460 formed on the right side plate portion 410e, and is fixed by a fastener (not shown) such as a screw. Support shafts 741 and 742 are provided at two locations on the upper and lower sides of the door support fitting 740, and each of the support shafts 741 and 742 has a tapered shaft portion extending upward. The door support fitting 740 supports the inner door 700 so as to be rotatable.

  On the other hand, a long bearing fitting 745 formed by bending a metal plate is fixed to the right end portion of the base 710 of the inner door 700 with a fastener (not shown) such as a screw. In the bearing bracket 745, support brackets 746 and 747 each having an insertion hole into which the shaft portion of each of the support shafts 741 and 742 is inserted are provided vertically corresponding to the respective support shafts 741 and 742 of the door support bracket 740. It has been. Then, by placing the support fittings 746 and 747 above the respective support shafts 741 and 742 and lowering the inner door 700, the shaft portions of the support shafts 741 and 742 are inserted into the insertion holes of the support fittings 746 and 747. It is assumed that it was done. Thus, the inner door 700 is supported so as to be rotatable about an opening / closing axis extending in the vertical direction connecting the both support shafts 741 and 742 to the inner casing 410, and the front of the inner casing 410 is opened by the rotation. The side can be opened and closed.

  A long hook receiving metal fitting 750 is fixed to the left side plate portion 410d of the inner housing 410 with a fastener (not shown) such as a screw along the inner peripheral edge of the opening of the housing 11 (see FIG. 18). . A pair of upper and lower hook receiving portions 751 and 752 are provided on the hook receiving metal 750, and a guide piece 753 extending horizontally in the front-rear direction is bent at the lower part of the hook receiving metal 750.

  On the other hand, on the left end side of the inner door 700, that is, on the opposite side of the opening / closing axis of the inner door 700, a door locking fitting 760 is provided on the back surface thereof. The door locking bracket 760 includes a base frame 761 that extends in the vertical direction and is fixed to the base 710, a long interlocking bar 762 that is assembled to the base frame 761 so as to be movable in the vertical direction, And a guide block 763 made of resin in a substantially rectangular parallelepiped shape corresponding to the guide piece 753 of 750. The interlocking rod 762 is provided with a pair of upper and lower metal fittings 765 and 766 having a hook shape corresponding to the hook receiving portions 751 and 752, and when the inner door 700 is closed with respect to the inner housing 410. In this case, the inner door 700 is held in a closed state by the hook fittings 765 and 766 being locked to the hook receiving portions 751 and 752. When the inner door 700 is closed, the lower surface of the guide block 763 rides on the upper surface of the guide piece 753 and is guided so that vertical positioning is performed. For this reason, the metal fittings 765 and 766 are reliably guided to the metal hook receiving portions 751 and 752 without being displaced in the vertical direction.

  In addition, an operation piece 767 that projects downward from the inner door 700 is provided at the lowermost portion of the interlocking rod 762. More specifically, the operation piece 767 includes a bent portion 768 formed by bending the lower end portion of the interlocking rod 762 toward the bearing fitting 745 at a right angle. By depressing the operation piece 767 (bending portion 768), the interlocking rod 762 is moved downward. Since each of the metal fittings 765 and 766 is provided with an urging member such as a coil spring that urges toward the side where the locked state is maintained, as described above, when the operation piece 767 is pushed down, the interlocking rod 762 moves downward. Then, by moving the metal fittings 765 and 766 against the urging force of the urging member, the locked state between the metal fittings 765 and 766 and the collar receiving portions 751 and 752 is released, and the inner housing The closed state of the inner door 700 with respect to the body 410 is released.

  Since the operation piece 767 is formed by being bent as described above, a finger is hooked on the operation piece 767 (bending portion 768) when the operation is performed from the inside of the surface changing unit 400, that is, from the opening / closing base axis side of the inner door 700. Can be pushed down easily. If an operation from the outside of the surface changing unit 400 is performed, the operation piece 767 is bent in the opposite direction, so that it is difficult to hook a finger or the like and it is difficult to push down. For this reason, when the tool or the like is illegally inserted from the gap between the casing 11 adjacent to the operation piece 767 and the front door 12 in a state where the surface changing unit 400 is completely attached to the casing 11, It becomes operation, and push-down operation becomes difficult. Further, when the tool enters as described above, access to the bent portion 768 is hindered by the vertical portion of the operation piece 767. In addition, since the entry direction of the unauthorized tool and the operation direction of the operation piece 767 are difficult to be the same, the unauthorized operation becomes even more difficult.

  Next, an outline of the main control device 770 accommodated together with the reel device 650 in the inner casing 410 will be described with reference to FIG. 26 (a perspective view seen from the front side of the main control device).

  The main controller 770 includes a substantially horizontally long main control board (not shown) on which electronic components such as a CPU and a memory are mounted, and a case member (a case base 772 and a case cover 773 for housing the main control board. ) And a movable base plate 774 that is detachably mounted by sliding the case member. The case base 772, the case cover 773, and the movable base plate 774 all have a substantially horizontal rectangular shape so as to match the main substrate control board, and are formed of a transparent synthetic resin material such as polycarbonate resin. Through the transparent case base 772, the case cover 773, and the movable base plate 774, the main control board disposed therein can be seen.

  The movable base plate 774 has a substantially long bottom plate portion 775, and side plates 776 and 777 for supporting the case member are formed on the long side of the bottom plate portion 775. A step portion 778 is formed on one side portion of the short side of the bottom plate portion 775 so as to be continuous with the same side plate portions 776 and 777, and a mounting opening for slidingly mounting the case member on the short side on the opposite side. 779 is formed. In this case, the case member is inserted into the predetermined position on the movable base plate 774 by inserting the case member from the mounting opening 779 and sliding it until it contacts the stepped portion 778.

  In addition, a pair of bearing hole portions 780 and 781 are provided on the short side of the movable base plate 774 on the same side as the stepped portion 778 along the short side, corresponding to these bearing portions 780 and 781. A support bracket (not shown) having a support shaft is provided on the front surface and upper left of the back plate portion 410c. In such a configuration, the support base of the support fitting is inserted into the bearing portions 780 and 781 of the movable base plate 774 so that the movable base plate 774 is attached to the support fixture in a rotatable state (see FIG. 6). .

  In the above configuration, by arranging the main control device 770 so that the electronic component mounting surface of the main control board faces forward, fraud confirmation on the main control board is facilitated. Further, the movable base plate 774 is rotated about 90 degrees about the support shaft as a rotation center, so that the rotation front end side of the main control device 770 is drawn toward the near side. In such a state, it becomes possible to visually recognize the back side of the main control device 770 (the surface opposite to the electronic component mounting surface of the main control board), and whether there are any abnormalities or frauds in various electronic components, electrical wiring, etc. Confirmation can be made.

  Incidentally, in the actual configuration of the slot machine 10, as shown in FIGS. 6, 18, etc., the front space of the main control device 770 is opened, and there is nothing to turn the movable base plate 774 forward. There will be no hindrance. Even if a device or mechanism that protrudes rearward of the slot machine is provided on the back surface of the inner door 700, the front space of the main controller 770 is opened as the inner door 700 is opened, and the movable base plate 774 is also rotated. Will not cause any problems. Further, even when the movable base plate 774 is rotated about 90 degrees at the maximum, the left side plate portion 410d is provided with the upper opening 450 for avoiding interference with the main controller 770, so that the rotation operation is performed. There will be no hindrance.

  The case base 772 and the case cover 773 are provided with a plurality of sealing portions (so-called crimping portions) (not shown) as sealing means for connecting these members. These sealed parts allow the case members 772 and 773 to be opened by being accompanied by destruction and the like, and the members that have been destroyed remain as the opening history after opening, so that the opening fact is confirmed by the opening history. It is possible. In addition, a plurality of (two in the present embodiment) rectangular seal seals S1 are attached to the case base 772 and the case cover 773 so as to straddle both. When the seal seal S1 is once affixed and then peeled off, the adhesive is peeled off from the seal label and cannot be affixed again. When the seal seal S1 is peeled off, the trace remains. It can be confirmed whether or not the main control board has been removed from the member. With this configuration, in the case where the case member is illegally opened, for example, an illegal act can be found by checking the sealed portion.

  On the other hand, in a state where the case member is mounted on the movable base plate 774, a rectangular seal seal S2 is attached so as to straddle the movable base plate 774 and the case cover 773. Similarly to the seal seal S1, the seal sticker S2 is once peeled off after being applied, and the adhesive is peeled off from the seal label and cannot be applied again. When the seal sticker S2 is peeled off, the seal seal S2 has a trace. Since it remains, it can be confirmed whether or not the case member has been removed from the movable base plate 774. Although not shown, the side plate portion 777 of the movable base plate 774 and the case member are provided with a plurality of sealing portions (so-called caulking portions) that couple them together. Whether or not the case member has been removed from the movable base plate 774 can also be confirmed by the destruction history of these sealing portions.

  As shown in FIGS. 18 to 20, a long plate-like partition plate 791 is horizontally placed between the left side plate portion 410d and the right side plate portion 410e above the reel device 650 (the front side of the housing recess 442). Is provided. A relay board 790 for electrical connection between the main controller 770 and the various devices such as the reel device 650 is mounted on the upper surface of the partition plate 791, and is provided corresponding to the relay board 790. The case body 792 is covered. The case body 792 is formed of a transparent synthetic resin material such as polycarbonate resin, and the relay substrate 790 disposed inside the case body 792 is visible. In addition, in FIGS. 13-19, since it is difficult to confirm the relay board | substrate 790, please refer to the perspective view of FIG.

(Description of connector connection mechanism)
Here, based on FIG. 9, FIG. 16, the connection mechanism for electrically connecting the surface changing unit 400 and the housing | casing 11 is demonstrated.

The housing connectors 811 and 812 and the face change connectors 841 and 842 can be coupled with each other in a state of being mounted on the housing 11. Each component will be described in detail below.

(Description of housing connectors 811 and 812)
First, the outline of the housing connectors 811 and 812 will be described with reference to FIG. The housing connectors 811 and 812 are such that the insertion ports 811a and 812a into which the face change connectors 841 and 842, which are coupling partners, are inserted face the front of the slot machine, that is, the front side of the inner case 410 (the face change unit 400). Thus, they are juxtaposed side by side on the front upper part of the back plate 11c of the housing 11. By inserting the surface changing connectors 841 and 842 into the housing connectors 811 and 812, the housing connectors 811 and 812 and the surface changing connectors 841 and 842 are electrically connected. A harness (not shown) is connected to the rear portions of the housing connectors 811 and 812, and the harness is guided to a lower portion of the housing 11 through a groove (not shown) formed in the back plate 11c. 100, the hopper device 110, and the like.

  Since the left and right housing connectors 811 and 812 have the same configuration and the same mounting structure with respect to the back plate 11c, the mounting structure of the left housing connector 811 will be described in detail with reference to FIG. . Fig.27 (a) is the elements on larger scale of FIG. 9, FIG.27 (b) is the sectional view on the AA line of the figure.

  A substantially rectangular metal base plate 445 extending to the left and right is fixed to the upper part of the back plate 11c by a fastener such as a screw. The left side of the inner surface of the base plate 445 has a horizontally long plate shape. A printed circuit board 813 is provided. The board base plate 445 is provided with leg portions 446 extending toward the front for mounting the printed board 813 corresponding to the left and right ends of the printed board 813. The printed board 813 is connected to the front surface of the board base plate 445. It is being fixed to the leg part 446 with fasteners, such as a screw, in the state which has space between.

  The housing connector 811 has a substantially rectangular shape that is horizontally long when viewed from the front of the slot machine 10, and has a box-shaped connector body 811b having an opening (insertion opening 811a) on the front surface, and a connector body 811b on the back side of the connector 811. Projecting portions 815 projecting to the left and right at both sides. The housing connector 811 is arranged in a state in which the back side of the overhanging portion 815 as an attachment portion to the printed board 813 is in contact with the printed board 813. The printed board 813 is provided with a substantially rectangular relief hole 817 at a portion facing the connector main body 811b. The space provided between the printed board 813 and the board base plate 445 described above and the escape hole 817 are provided. The harness is connected to the rear side of the housing connector 811.

  A gate-shaped support member 819 opened upward as viewed from the front of the slot machine 10 is provided so as to surround both side portions and the lower portion of the connector main body 811b. On both sides of the support member 819, connector fixing portions 821 are formed for fixing the protruding portions 815 of the housing connector 811 while being sandwiched between the printed circuit boards 813. The fixing structure of the housing connector 811 will be described in detail. Fasteners such as screws (not shown) are provided on the legs of the printed circuit board 813 and the overhanging portions 815 of the housing connector 811 from the back side of the printed circuit board 813. A through hole for communicating is formed, and a fixing portion for screwing and fixing a fastener (not shown) such as a screw is formed in the connector fixing portion 821 of the support member 819 correspondingly. Yes. That is, the printed circuit board 813, the housing connector 811, and the support member 819 are attached to the circuit board base plate 445 in a state of being integrally coupled. Note that the right housing connector 812 shown in FIG. 9 is similarly fixed to the substrate base plate 445 by the printed circuit board 814 and the support member 820.

  A lower support portion 823 that protrudes forward along the bottom of the housing connector 811 is provided below the support member 819, and the front end portion thereof faces the insertion port 811 a of the housing connector 811. The guide inclined surface 827 that is inclined is formed, and details of the guide inclined surface 827 will be described later.

(Description of surface change connectors 841, 842)
Next, the surface changing connectors 841 and 842 will be described. As shown in FIGS. 14 and 16, the surface changing connectors 841 and 842 are arranged side by side at the positions corresponding to the housing connectors 811 and 812 on the bottom of the housing recess 442 of the back plate portion 410c. The surface changing connectors 841 and 842 are in a state where the insertion portions 841a and 842a to be inserted into the insertion ports 811a and 812a of the housing connectors 811 and 812 are directed to the rear side in the attaching / detaching direction of the inner housing 410 (the surface changing unit 400). Further, it is attached to the housing recess 442 via a long plate-like support 843. The housing recess 442 is formed with a laterally long hole 443 that penetrates inward and outward corresponding to the surface change connectors 841 and 842, and the surface change connectors 841 and 842 and the main control are formed through the hole 443. A device 770 and the like are connected by a harness (not shown).

  In more detail, a part of the connectors 841 and 842 protrudes to the inside of the support body 843 (the front side of the slot machine 10) to form an in-unit coupling portion 841c, and by the in-unit coupling portions 841c and 842c, Electrical connection is made with the main controller 770 in the unit (see FIG. 18 and the like).

  Since each of the left and right surface changing connectors 841 and 842 has the same mounting structure, the mounting structure of the left surface changing connector 841 (the right housing connector in FIGS. 14 and 16) will be described with reference to FIG. This will be described in detail. FIG. 28A is a partially enlarged view of FIG. 16, and FIG. 28B is a cross-sectional view taken along the line BB of FIG.

  The face change connector 841 has a horizontally long and substantially rectangular shape corresponding to the housing connector 811 when viewed from the rear of the slot machine 10, and has a box-like connector body 841b having an opening (insertion portion 841a) on the front. On the front side of the connector 841 (left side in FIG. 28 (b)), there is an overhanging portion 845 that protrudes to the left and right at both sides of the connector main body 841b. A round hole 846 penetrating in the front-rear direction is provided in the approximate center of the overhang portion 845.

  The support body 843 is provided with a fastening hole 847 penetrating inward and outward at a position corresponding to the round hole 846, and a screw 848 is inserted from the rear of the round hole 846 (right side in FIG. 28B). The surface change connector 841 is attached by screwing the tip of 848 into the fastening hole 847. The outer diameter of the shaft portion 849 of the screw 848 that constitutes the insertion portion for the round hole 846 is formed smaller than the inner diameter of the round hole 846, and the overhang portion 845 of the housing connector 841 is a washer that the screw 848 has. It is sandwiched between 850 and the support body 843. In other words, the housing connector 841 itself is not fixed by the screw 848 and is held in a state where movement in the front-rear direction is restricted by the washer 850 and the support body 843. The housing connector 841 is configured to be movable within a range where the inner wall of the round hole 846 abuts on the shaft portion 849 of the screw 848, that is, within a range of a gap formed by the round hole 846 and the shaft portion 849. . Note that the housing connector 841 can be prevented from coming off from the screw 848 by setting the outer diameter of the washer 850 in consideration of the movable range of the housing connector 841. In the present embodiment, the axial direction of the screw 848 is configured to be the same as the mounting direction of the inner casing 410, and the casing connector 841 is in all directions orthogonal to the mounting direction of the inner casing 410. It is configured to be movable about 2 mm. In a state where the surface changing connector 841 is detached from the housing connector 811, the surface changing connector 841 is positioned at the lower limit within the movable range with its own weight action. More specifically, the lower limit position is uniquely determined by the concentric configuration of the screw 848 and the round hole 846. Thereby, the guide inclined surface 827 of the support member 819 is provided corresponding to the lower limit position within the possible range of the surface changing connector 841.

  As described above, the direction in which the surface changing unit 400 is pushed into the housing 11 and the direction in which the connectors 811, 812, 841, and 842 are combined are unified, so that the inner housing 410 (the surface changing unit 400) can be connected. The face change connectors 841 and 842 and the case connectors 811 and 812 can be coupled together with the pushing operation to the case 11. Similarly, the surface changing connectors 841 and 842 and the housing connectors 811 and 812 can be separated by a pulling operation of the inner housing 410. For this reason, in the replacement work of the surface changing unit 400, there is no need for the operator to separately perform operations for inserting and connecting the respective connectors 811, 812, 841, and 842, and releasing the connection by separating them. As a result, the replacement work of the surface changing unit 400 can be performed efficiently.

  Further, as shown in FIG. 27, guide inclined surfaces 860 are formed on the upper and lower surfaces inside the housing connector 811 so as to be inclined so that the vertical interval becomes narrower from the insertion port 811a of the connector 811 toward the back side. In addition, on the left side surface and the right side surface inside the housing connector 811, a guide inclined surface 861 that is inclined so that the distance between the left and right sides becomes narrower toward the back side of the connector 811 is formed. In other words, the inside of the connector main body 811b of the housing connector 811 is formed so as to widen toward the insertion port 811a, and the insertion port 811a is configured to be larger than the insertion portion 841a of the surface changing connector 841. Has been. These guide inclined surfaces 835 and 836 together with the guide inclined surface 827 constitute connector guide means for guiding the connection of the housing connector 811 to the surface changing connector 841. Similarly, the right housing connector 812 has a guide inclined surface (not shown), and the right support member 816 also has a guide inclined surface (not shown).

  By providing the guide inclined surfaces 827 and the guide inclined surfaces 835 and 836 as the connector guide means, the surface replacement connectors 841 and 842 that are movably provided in accordance with the pushing operation of the surface replacement unit 400 into the housing 11 are provided. Is adjusted in accordance with the housing connectors 811 and 812. More specifically, when the surface changing unit 400 is pushed into the housing 11, first, the insertion portions 841 a and 842 a of the surface changing connectors 841 and 842 are brought into contact with the guide inclined surface 827, whereby the housing connectors 811 and 812. When it is guided to the insertion ports 811a and 812a and further pushed in, it is urged to move in the vertical and horizontal directions by the guide inclined surfaces 835 and 836 and is guided to a predetermined coupling position. Thereby, the position adjustment of the surface changing connectors 841 and 842 with respect to the housing connectors 811 and 812 is completed. Therefore, in the replacement work of the surface changing unit 400, it is not necessary for the operator to adjust the insertion positions of the connectors 811, 812, 841, 842, so that the replacement work of the surface changing unit 400 can be performed more easily. It becomes possible. Furthermore, as described above, since the housing connectors 811 and 812 can move in any direction such as up and down and left and right even in the coupled state, a force is applied in a direction different from the attaching / detaching direction when replacing the surface changing unit 400. Even if it adds, it can prevent that force concentrates on the connection location of connector 811,812,841,842. Thereby, damage to the connectors 811, 812, 841, 842 can be avoided. Further, in the present embodiment, the surface changing connectors 811 and 812 are configured to be movable within a predetermined gap, and the connector is configured to be movable in a state of being regulated by a regulating member such as a spring. I don't mean. That is, it is not a configuration in which the position adjustment is performed by deforming the regulating member. For this reason, it is hard to produce a load in the part which restrict | limits the movement of a connector, and can respond suitably also to repeated use.

  In the present embodiment, since the guide inclined surface 827 and the lower guide inclined surface 860 of the support member 819 are provided so as to be continuous, when the housing connectors 811 and 812 are connected, It is possible to suppress a problem that the housing connectors 811 and 812 are caught between the guide inclined surface 827 and the lower guide inclined surface 860.

  In this way, when the surface changing connectors 841 and 842 are inserted into the housing connectors 811 and 812, the surface changing connectors 841 and 842 and the housing connectors 811 and 812 are electrically connected, A control signal from the main control device 770 is output to the hopper device 110 and the like, and power from the power supply box 100 is supplied to the main control device 770 and the reel device 650 and the like.

  In the present embodiment, as described above, when the surface changing unit 400 is moved to a predetermined position at the back of the housing, the momentum of pushing the surface changing unit is reduced by using frictional resistance. When the surface change connectors 841 and 842 collide with the housing connectors 811 and 812 vigorously, it is possible to suitably suppress problems such as breakage of the connectors 811, 812, 841 and 842.

  Further, in the mounting state of the surface changing unit 400 to the housing 11 (connection state of the connectors 811, 812, 841, 842), the shape of the housing recess 442 is changed to the printed circuit board 813, 814, the support members 819, 820, and It is formed so as to avoid interference with the housing connectors 811 and 812. By doing so, the back plate portion 410c of the surface changing unit 400 and the back plate 11c of the housing 11 can be arranged close to each other so that the depth inside the housing 11 can be used effectively, and each connector 811 can be used. , 812, 841, 842 can be shielded from the surrounding gaps, so that it is possible to prevent fraudulent acts on the connection parts of the connectors 811, 812, 841, 842.

(Description of the completed state as the surface changing unit 400)
The completed state of the surface changing unit 400 will be described again with reference to FIGS. As the surface changing unit 400, a reel device 650 is attached inside the inner housing 410, and a relay board 790 is attached above the reel device 650 via a partition plate 791. A main controller 770 is fixed to the back plate 410c above the relay board 790, and an inner door 700 serving as a liquid crystal display means is attached to the front surface of the inner casing 410.

  A part of each of the reels 655 to 657 of the reel device 650 can be visually recognized from the display window 723 of the liquid crystal display device 711 provided on the inner door 700 on the front side of the surface changing unit 400. More specifically, among the many symbols (21 in this embodiment) attached to the outer periphery of each of the reels 655 to 657, three symbols for each reel can be visually recognized through the display window 723. ing.

  A design plate (not shown) on which a design such as a character unique to the gaming machine is attached is attached to the shielding portion 721 of the front frame 720 provided in the inner door 700. The design plate is configured to be visible from the front of the gaming machine in a state where the inner door 700 is closed by the inner housing 410. Moreover, the shielding part 721 is provided in front of the main control device 770, and the inconvenience that the main control board 771 is directly visually recognized from the outside in front of the surface changing unit 400 can be suppressed. That is, the inner door 700 is provided so as to close the opening of the inner casing 410 almost entirely in the front view of the surface changing unit 400. It can be said that the inner door 700 constitutes a shielding unit that shields the inside of the inner housing 410 from the outside.

  As described above, in the surface changing unit 400, the inner door 700 is pivotally supported by the door support fitting 740 so that it can be easily removed from the inner housing 410 without using a special tool or the like. . As a result, by providing the display control device 730 on the inner casing 410 side, the inner door 700 can be reused. That is, it is possible to improve the reusability of the components of the slot machine 10.

(Description of replacement work of the surface changing unit 400)
Here, replacement work of the surface changing unit 400 at the time of model change in the game hall will be described. In this case, first, the front door 12 is unlocked using a prescribed operation key K (see FIG. 3), and the front door 12 is opened at a predetermined angle or more. Next, by pushing down the operation piece 767 provided at the lower left portion of the inner door 700, the latched state of the metal fittings 765 and 766 that lock the inner door 700 to the inner housing 410 is released. Then, after opening the inner door 700 at a predetermined angle or more, the operation unit 615 of the lever member 610 provided in the surface changing unit 400 is tilted to the front side to release the locked state of the surface changing unit 400. Only the inner door 700 is closed. Then, the surface changing unit 400 is pulled toward the front side along the support rail 300, and when the inner casing 410 is caught (once stopped), the front side is lifted by about 10 °. If the resin piece 330 is brought into contact with the resin piece 330 just before being detached, the same surface changing unit 400 is detached by further pulling it toward the near side.

  After that, the new surface changing unit 400 is mounted in the operation procedure almost opposite to that at the time of detachment. That is, the new surface changing unit 400 is pushed into the rear side of the housing 11 so as to be along the support rail 300, and when the new surface changing unit 400 comes into contact with the bent portion 251, the pushing of the surface changing unit 400 is finished. Thereafter, by closing the front door 12, the slot machine 10 is locked, and the replacement of the unit is completed. Note that the lower plate 80 is also replaced when the model is replaced.

  At the time of replacement work, electrical wiring connectors 811, 812, 841, and 842 that connect the surface changing unit 400 and various other members (the power supply box 100, the hopper device 110, etc.) are pushed by the pushing operation of the surface changing unit 400 Since it is connected and the connection is released by the pulling operation, it is not necessary to separately connect and release the connectors 811, 812, 841, and 842.

(Description of completed state of slot machine 10)
The completed state of the slot machine 10 will be described again with reference to FIGS. As the slot machine 10, various components such as the surface changing unit 400 are housed in the housing 11, and the front door 12 is provided so as to close the opening of the housing 11. The liquid crystal display device 711 of the surface changing unit 400 can be viewed from the viewing windows 21 and 22 provided on the front door 12, and one of the reels 655 to 657 can be viewed from the viewing window 22 via the display window 723 of the same surface changing unit 400. The part is visible.

  As shown in FIG. 29 (schematic diagram showing a state in which the surface changing unit is mounted on the side surface of the slot machine), the inner housing 410 of the surface changing unit 400 has the front portion of the inner housing 410 as the opening of the housing 11. It is mounted to protrude forward. That is, the boundary B1 between the inner housing 410 and the inner door 700 is shifted in the depth direction with respect to the boundary B2 between the front door 12 and the housing 11. Specifically, the boundary B1 between the inner housing 410 and the inner door 700 is arranged in front of the boundary B2 between the front door 12 and the housing 11. The hook receiving portions 221 and 222 of the hook receiving metal 220 are provided on the rear side of both the boundaries B1 and B2. In other words, the flange receiving portions 221 and 222 are provided at positions sandwiched between the right side plate 11e of the housing 11 and the right side plate portion 410e of the inner housing 410. As described above, since the collar receiving portions 221 and 222 are provided behind the gap and sandwiched between the right side plate 11e and the right side plate portion 410e, the opening edge of the housing 11 and the front door 12 are provided. It becomes difficult to open the front door 12 by allowing a wire, a film, or the like to enter from the gap (boundary B2) between the portions facing the rear end of the outer periphery. Therefore, cheating can be suppressed.

  The back plate portion 410c is substantially flat as seen in FIG. 24 (schematic diagram), and the back plate portion 410c is attached to the back plate 11c in a state where the surface changing unit 400 is mounted in the housing 11. It is formed so as to be substantially parallel to the case, and the depth region of the housing 11 can be utilized to the maximum extent. 9 and 15, the side plate portions 410d and 410e and the housing 11 are formed so as to be substantially parallel to the inner peripheral surface (side plates 11d and 11e) of the housing 11, respectively. By doing so, the region in the left-right direction of the housing 11 can also be used effectively.

  In addition, the housing recess 452 of the inner housing 410 is formed in such a size that the front door 12 and the inner housing 410 do not interfere when the surface changing unit 400 moves in the mounting direction. More specifically, if the front door 12 is opened at a predetermined angle or more without removing the front door 12, it is configured not to interfere. As a result, the operator can perform a push-in operation and a pull-out operation straight toward the mounting direction without worrying about interference with the front door 12 while the front door 12 is mounted. Therefore, workability can be improved.

  As shown in FIG. 5, in the present embodiment, the open / close base end shafts of the front door 12 provided in the housing 11 and the inner door 700 provided in the inner housing 410 are provided on the left and right sides, respectively. The configuration. For this reason, in order to open the inner door 700 and access the main control device 770 mounted inside the inner casing, it is necessary to open the front door 12 by a predetermined angle or more. That is, in order to gain unauthorized access to the main control device 770, the front door 12 needs to be opened wide, making it difficult to create blind spots from the game hall staff and surveillance cameras, thereby preventing fraud. . Even if it is performed, it is easy for a staff of a game arcade or a surveillance camera to catch it, so that it is possible to easily find fraud.

  Furthermore, since the operation piece 767 for opening the inner door 700 is provided on the opening / closing base side of the front door 12, it is necessary to open the front door 12 by a predetermined angle or more in order to operate the operation piece 767 (see FIG. 4). That is, it is difficult to open the front door 12 a little and release the locked state of the inner door 700. For this reason, it is possible to prevent the main controller 770 from being accessed from the gap in a state where the doors 12 and 700 are slightly opened.

  As described above, unauthorized access from the outside is suitably suppressed inside the surface changing unit 400. For this reason, by accommodating the component parts of the slot machine 10 that are likely to be fraudulent in the surface changing unit 400, it is possible to expect fraud suppression performed on those component parts. In the present embodiment, the power supply box 100 is provided with the reset switch 102 for resetting various states of the slot machine 10 and the setting key insertion hole 103 for adjusting the payout of medals. The reset switch 102 and the setting key insertion hole 103 may be provided in the inside of the surface changing unit 400, for example, in the main controller 770. As a result, it is possible to suppress a fraud such as changing the ball setting of the slot machine 10 using a fraudulent tool such as a wire.

  As shown in FIG. 4, a configuration including gutter receiving portions 221 and 222 for closing the front door 12 in a space between the side plates 11 d and 11 e of the housing 11 and the side plate portions 410 d and 410 e of the surface changing unit 400. It was. That is, the hook receiving portions 221 and 222 are disposed in a region sandwiched between the surfaces. Thereby, even if it tries to remove a heel using a wire, a cellophane, etc., the movement allowable range can be controlled and improper opening of front door 12 can be controlled.

  As shown in FIG. 6, in the lever member 610 for performing the unlocking operation of the surface changing unit 400, the operation portion 615 communicates with the inside and outside of the surface changing unit 400. The exposed portion of the operation unit 615 that can be operated from the outside of the surface changing unit 400 is in a space sandwiched between the side plates 11 d and 11 e of the housing 11 and the side plate portions 410 d and 410 e of the surface changing unit 400. For this reason, it is difficult and time-consuming to insert a finger or wire into the above space for the purpose of releasing fraud. It becomes possible to do. On the other hand, since the operation from the outside is possible as described above, even when it is difficult to open the inner door 700 due to a failure of the closing mechanism of the inner door 700, the locking state of the surface changing unit 400 is changed to the outside. And the same surface changing unit 400 can be removed. In the present embodiment, the lever member 610 is configured to be operable from inside and outside of the surface changing unit 400. However, the operation unit 615 is completely isolated from the outside of the surface changing unit 400, so that the unauthorized operation can be performed more appropriately. It is good also as a structure which can suppress operation.

  The casing 11 and the surface changing unit 400 are provided with a plurality of sealing portions (so-called caulking portions) as sealing means for connecting the two. Specifically, the unit side round hole 413 provided in the surface changing unit 400 (specifically, the reinforcing plate 411) and the case side round hole (not shown) provided in the housing 11 are separated by a caulking band (not shown). Linked in an impossible state. These sealing portions (caulking bands) enable the removal of the surface changing unit 400 by being accompanied by destruction and the like, and the members that have been destroyed remain as the opening history after the removal. It is possible to confirm the opening fact. With this configuration, if the surface changing unit 400 is illegally removed, for example, it is possible to find an illegal act by checking the seal portion.

(Explanation of electrical configuration)
Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main controller 770 is equipped with a microcomputer centering on a CPU 901 that is arithmetic processing means. In addition to the power supply device 902 provided in the power supply box 100, the CPU 901 is connected to a clock circuit 903 that outputs a rectangular wave having a predetermined frequency, an input / output port 904, and the like via an internal bus. The main control device 770 functions as a main board built in the slot machine 10.

  On the input side of the main controller 770, there are a start detection sensor 921 that detects the operation of the start lever 45, stop detection sensors 922, 923, and 924 that individually detect the operations of the stop switches 50 to 52, and the medal insertion device 30. An inserted medal detection sensor 925 that detects an inserted medal, bet detection sensors 926 and 927 that individually detect operations of the bet switches 40 and 41, an adjustment detection sensor 928 that detects an operation of the adjustment switch 55, and each reel 655. A reel index sensor 929 that individually detects the rotational position (origin position) of 657, a payout detection sensor 930 that detects medals paid out from the hopper device 110, and a reset detection sensor that detects an operation of the reset switch 102 provided in the power supply box 100 931, in the setting key insertion hole 103 Various sensors such as a setting key detection sensor 932 for detecting that the fixed key is inserted are connected, and signals from these various sensors 921 to 932 are output to the CPU 901 via the input / output port 904. ing.

  The inserted medal detection sensor 925 is actually composed of a plurality of sensors. That is, the storage passage 32 from the medal insertion device 30 to the hopper device 110 is configured so that medals can pass in one row. The storage passage 32 is provided with a first sensor, and the second sensor and the third sensor are close to each other on the downstream side more than the width of the medal. The inserted medal detection sensor 925 is constituted by each of the first to third sensors. The main controller 770 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, the main control device 770 considers that there is 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 770 also monitors the order in which the second sensor and the third sensor are turned on / off, the second and third sensors are both off, only the second sensor is on, and the second and third sensors are both 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 a fraud in which a medal is reciprocated near the inserted medal detection sensor 925 and misidentified as a medal inserted in addition to a clogged medal in the storage passage 32.

  Further, a power failure monitoring circuit 902 b provided in the power supply device 902 is connected to the input side of the main control device 770 via an input / output port 904. The power supply device 902 includes a power supply unit 902a that supplies driving power to the electronic devices of the slot machine 10 including the main control device 770, the power failure monitoring circuit 902b described above, and the like.

  The power failure monitoring circuit 902b monitors the power shutoff state and generates a power failure signal not only at the time of a power failure but also at the time of power failure by a power switch provided in the power supply box. For this reason, the power failure monitoring circuit 902b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 902a, and determines that the power supply is shut off when the drive voltage drops below, for example, 10 volts. Is configured to output a power failure signal. The power failure signal is supplied to each of the CPU 901 and the input / output port 904, and the CPU 901 recognizes this power failure signal and executes a power failure process.

  The power supply unit 902a is configured to output a stabilized voltage of 5 volts that is used as a drive voltage in a control system such as the main controller 770 even when the output voltage drops below 22 volts. As the time during which the stabilization voltage is output, sufficient time is secured to execute the power failure process by the main controller 770.

  On the output side of the main control device 770, each stepping motor for rotating the reels 655 to 657, etc., such as a medal path switching solenoid provided in the selector 31, a hopper device 110, a display control device 730, a hall management device (not shown) An external centralized terminal board 945 and the like that can transmit information to and the like are connected via an input / output port 904.

  The display control device 730 is a control device for driving various lamps such as the central lamp unit 26, various speakers provided on the rear side of the speaker units 82 and 83, and the liquid crystal display device 711. A substrate on which a CPU, a ROM, a RAM, and the like are integrated is provided. Then, after receiving a signal from the main control device 770, the display control device 730 independently controls various lamps, various speakers, and the liquid crystal display device 711. Therefore, the display control device 730 is a sub-board that performs auxiliary control in relation to the main control device 770 that is a main board that manages and manages games. In other words, a sub-board is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main board.

  The CPU 901 described above stores various control programs executed by the CPU 901 and ROM 952 storing fixed value data, and temporarily stores various data when executing the control program stored in the ROM 952. In addition to the RAM 953 for securing the area, although not shown, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, a data transmission / reception circuit, etc., as well known, and a credit counter for counting the number of credits Various counters such as are built-in. The ROM 952 and the RAM 953 constitute a main memory as storage means, and various programs are stored in the ROM 952 described above as part of the control program.

  The RAM 953 is configured to hold (backup) data by being supplied with a backup voltage from the power supply device 902 even after the power of the slot machine 10 is cut off. The RAM 953 temporarily stores various data and the like. In addition to the memory and area for storing, a backup area is provided.

  The backup area includes a stack pointer, each register, and I when power is shut down due to the occurrence of a power failure or the like (including power shut-down by operating a power switch provided in the power box 100; the same applies hereinafter). This is an area for storing values such as / O, and when the power failure is resolved (including power-on by operating the power switch; the same applies hereinafter), the state of the slot machine 10 is based on the backup area information. It is possible to return to the state before the power was shut off. Writing to the backup area is executed when the power is cut off by the power failure process, and restoration of each value written to the backup area is executed in the main process when the power is turned on. Note that the power failure signal from the power failure monitoring circuit 902b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 901 when the power is interrupted due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  When the surface changing unit 400 is attached to the housing 11, the surface changing unit 400 is pushed along the support rail 300 toward the back side of the housing 11. As the surface change unit 400 reaches the mounting completion position, the lever member 610 (specifically, the locking claw portion 617) on the surface change unit 400 side and the support rail 300 (specifically, the upper guide portion 350a) on the housing 11 side are provided. The locked state is obtained, and the displacement of the surface changing unit 400 is suppressed. In this case, in addition to the pressing operation of the surface changing unit 400, a separate operation for bringing the surface changing unit 400 into a locked state is not required. For this reason, the mounting operation of the surface changing unit 400 can be facilitated, and the inconvenience of the operator forgetting to lock the surface changing unit 400 (lever member 610) can be avoided.

  Since the surface changing unit 400 is automatically locked by being pushed in as described above, the inner door 700 does not have to be opened when the surface changing unit 400 is mounted. That is, an operation such as opening the inner door 700 and locking the housing side and the unit side in the opened state becomes unnecessary. As shown in FIG. 13 and the like, a main controller 770 is provided in the interior of the surface changing unit 400, that is, in a space defined by the inner casing 410 and the inner door 700, and an opportunity to open the inner door 700 is provided. By reducing the number of times, the chance that the main controller 770 is exposed to the outside can be reduced. For this reason, it is possible to prevent the occurrence of fraud with respect to main controller 770.

  In the present embodiment, the mounting track is stabilized by pushing the surface changing unit 400 along the support rail 300, and the positional variation in the vertical direction when the surface changing unit 400 is mounted is reduced. . In such a configuration, since the positional relationship between the locking claw portion 617 and the upper guide portion 350a overlaps with each other in the vertical direction, the relative position between the two is less likely to vary in the vertical direction, and the transition to the locked state is smooth. Can be performed.

  By providing the lever member 610 at two positions on the left and right sides of the surface changing unit 400, the displacement of the surface changing unit 400 (position displacement due to sliding in the front and rear and left and right directions, and position displacement due to rotation on the horizontal plane) is more preferable. Can be suppressed. Thus, even when locking is performed at a plurality of locations, by pushing the surface changing unit 400, it is possible to achieve a locked state at all these locations, thus ensuring workability at the time of mounting. .

  As shown in FIG. 21 and the like, the lever member 610 is urged to the locked position by the leaf spring 631. For this reason, it becomes easy to maintain the latching state of the latching claw part 617 and the upper side guide part 350a. Even if the fraudster swings the slot machine 10 for the purpose of releasing the locked state, the locking claw portion 617 is separated from the upper guide portion 350a, that is, locked against the intention. Inconveniences such as being in a released state can be made difficult to occur.

  When removing the surface changing unit 400 from the housing 11, it is necessary to perform an unlocking operation of the surface changing unit 400. In such a case, the locking state between the locking claw portion 617 of the lever member 610 provided in the surface changing unit 400 and the upper guide portion 350a of the support rail 300 provided in the housing 11 is the front side of the operation portion 615 of the lever member 610. It can be released by pulling it down.

  Further, these operation units 615 are provided inside the surface changing unit 400, that is, in a space defined by the inner housing 410 and the inner door 700. In order to access the operation unit 615, not only the front door 12 but also the inner door 700 must be opened, and fraudulent acts are conspicuous. Therefore, it becomes difficult to open the inside door 700 illegally, and crime prevention can be improved. More specifically, one operation unit 615 (right operation unit 615) partially protrudes outside the surface changing unit 400 and can be accessed from the front of the slot machine 10. For this reason, there is a concern that the protruding portion of the other operation unit 615 (left operation unit 615) is illegally operated by an unauthorized tool such as a wire and the surface changing unit 400 is taken out. However, when the surface changing unit 400 is taken out, it is necessary to release the locked state of the left and right lever members 610, and it is difficult to perform an illegal operation of the left operation unit 615. It is possible to suppress unauthorized removal.

  The support rail 300 is fixedly provided on the housing 11, and a lever member 610 that is locked to the upper guide portion 350a of the support rail 300 is provided as a movable member in the surface changing unit 400, and the lever member 610 is rotated. It was set as the structure by which it switches between a latching state and a latch release state by moving. In the support rail 300, it is only necessary to secure a mounting space, and it is not necessary to secure a movable space of the upper guide portion 350a. Therefore, spatial restrictions in the housing 11 can be reduced.

  Since the lever member 610 is configured to be rotatable in a direction substantially parallel to the side plates 11 d and 11 e of the housing 11, the lever member 610 does not protrude to the inside of the housing 11 when the operation unit 615 is operated. Since the lever member 610 does not protrude to the inside of the housing 11 with the operation, inconveniences such as interference of the lever member with the side plates 11d and 11e of the housing 11, the reel device 650, and the like are suppressed.

  Furthermore, the lever member 610, that is, a locking tool (rotating type locking tool) having the operation unit 615 is provided on the surface changing unit 400 side. This simplifies the configuration of the locking tool on the housing 11 side (specifically, the upper guide portion 350a of the support rail 300) and suppresses the protrusion to the inside of the housing 11. Since the surface changing unit 400 is detachable from the housing 11, if the locking device on the housing 11 side is a rotation type locking device, the operation area of the operation unit must be secured. Therefore, the surface changing unit 400 is easily subjected to spatial restrictions. For this reason, as described above, it is possible to reduce the spatial restriction in the housing 11 by providing the operation unit on the side of the surface changing unit 400. Note that the number of parts is reduced by integrally molding the support rail 300 with the upper guide portion 350a serving as a case-side locking tool.

  As shown in FIG. 25, when the unlocking operation of the lever member 610 is performed in a state where the surface changing unit 400 is mounted in the housing 11, the unlocking position, that is, the locking claw portion of the lever member 610. 617 is held in a state of being separated from the upper guide portion 350 a of the support rail 300. For this reason, after the operator performs the unlocking operation, there is no need to hold the operation unit 615 with a finger or the like. Therefore, complication of the removal work of the surface changing unit 400 can be suppressed.

  The section in which the lever member 610 (specifically, the locking piece 621) is held is a range corresponding to the length of the upper guide portion 350a in the front-rear direction, and the holding state of the lever member 610 is pulled out of the surface changing unit 400. It will be canceled as a result. That is, it is not necessary for the operator to separately perform a holding state releasing operation at the unlocking position. For this reason, the attachment / detachment workability of the surface changing unit 400 can be ensured. For example, when the surface changing unit 400 is pulled out halfway and mounted on the housing 11 again, the holding state of the lever member 610 is released by the drawing of the surface changing unit 400. Therefore, it is possible to avoid the inconvenience that the lever member 610 remains held at the unlocking position and does not switch to the locked state even when the surface changing unit 400 is pushed to the mounting completion position. Therefore, it is possible to improve workability while reducing human error. Even when the surface changing unit 400 is completely removed from the housing 11 and then remounted, the holding state of the lever member 610 is released as described above, so that the locked state at the mounting completed position is restored. The transition is done reliably.

  The movement of the same surface changing unit 400 in the left-right direction is restricted by the boxes 480 and 490 of the housing 11 and the side plate portions 410d and 410e (specifically, guide ribs 470) of the inner housing 410 constituting the surface changing unit 400. Yes. For this reason, the positional variation to the left and right at the time of attaching and detaching the surface changing unit 400 is reduced, and the shift to the locked state between the locking claw portion 617 and the upper guide portion 350a can be performed more reliably. In the present embodiment, the pawl is held in the space formed between the side plates 11d and 11e of the housing 11 and the side plate portions 410d and 410e of the inner housing 410 (the housing recess 452 on the left side of the slot machine 10). Since the portion 617 is accommodated, it is difficult to visually recognize the locking claw portion 617 when the surface changing unit 400 is mounted. That is, it is difficult to guide to the upper guide part 350a while visually confirming the locking claw part 617. However, since the mounting track of the surface changing unit 400 is stabilized as described above, the locking claw portion 617 is reliably guided to the upper guide portion 350a when the surface changing unit 400 is mounted. Even if it is difficult to see the locking claw portion 617, there is no problem in mounting the surface changing unit 400. In addition, since the locking claw portion 617 is accommodated in the space formed between the side plates 11d and 11e and the side plate portions 410d and 410e, the locking claw portion 617 is accessed using an unauthorized tool such as a wire, It is possible to suppress fraud such as releasing the locked state. Therefore, it is possible to achieve both the improvement of the wearability of the surface changing unit 400 and the improvement of crime prevention.

  In addition, since there are two sections, a low friction section where the frictional resistance generated by the movement of the surface changing unit 400 is small and a high friction section where the frictional resistance is large, the surface changing unit 400 is easily moved in the low friction section. In the high friction section, the movement of the surface changing unit 400 is hindered by the frictional resistance. For this reason, even when the surface changing unit 400 is pushed in vigorously in the low friction section, the surface changing unit 400 can be braked in the high friction section, and the case where the surface changing unit 400 maintains the momentum. It is possible to avoid a collision with the 11 side. Therefore, for example, the surface changing unit 400 moves forward from the mounting completion position due to the reaction at the time of collision, and the transition to the locking state of the lever member 610 (movement to the locking position) is not performed as prescribed. Can be suitably avoided.

  For example, when an elastic member such as a spring or rubber is used to absorb the kinetic energy of the surface changing unit 400 by deformation of the spring or rubber, etc., it is locked by a reaction force (restoring force) of the rubber or the like. A load is generated on the claw portion 617 and the upper guide portion 350a. However, the slot machine 10 is configured to brake the surface changing unit 400 by using frictional resistance as described above. For this reason, in the mounting completion state of the surface changing unit 400, there is no energy (repulsive energy) for moving the surface changing unit 400 in a direction different from the mounting direction (for example, the detachment direction). Therefore, it is possible to avoid a load from being generated on the latching claw portion 617 and the upper guide portion 350a, and it is possible to suitably suppress functional deterioration and damage of the latching claw portion 617 and the upper guide portion 350a. .

  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 lever member 610 as the “unit side locking tool” is provided on both the left and right sides of the surface changing unit 400 (specifically, the inner housing 410). You may provide only. Desirably, the lever member 610 is provided on the open / close base end side of the inner door 700, that is, on the side where the door support fitting 740 that pivotally supports the inner door 700 is provided (in the present embodiment, on the right side in the slot machine front view). Good.

  (B) In the above embodiment, as shown in FIG. 13 and the like, the lever member 610 is provided in the lower portion of each side plate portion 410d, 410e of the inner casing 410, but this is changed to each side plate portion 410d, 410e. You may provide in the upper part of. For example, the left lever member 610 is configured to be housed together with the support rail 300 in the housing recess 452 formed in the lower portion of the left plate portion 410d, but above the housing recess 452 and above each side plate portion 410d. It is preferable to provide a configuration. Since the lower side of the inner casing 410 is supported by the support rail 300 of the casing 11, as described above, the movement of the inner casing 410 at the upper portion of the inner casing 410 is suppressed, so that the inner casing 410 can be installed in a completely mounted state. Stability can be further improved.

  (C) In the above embodiment, as shown in FIG. 21 and the like, a part of the operation portion 615 of the lever member 610 is connected to the side plates 11d and 11e of the casing 11 and the side plates of the inner casing 410 from the inside of the inner casing 410. Although it is configured to project into the space formed between the portions 410d and 410e, the operation unit may be completely accommodated in the inner housing 410. With this configuration, unauthorized access to the operation unit can be made more difficult in a state in which the surface changing unit 400 (inner housing 410) is completely attached to the housing 11. Note that the entire operation portion 615 of the lever member 610 may be provided in a space formed between the side plates 11d and 11e and the side plate portions 410d and 410e of the inner housing 410.

  (D) In the above embodiment, even when the operation unit 615 of the lever member 610 is operated in a state where the surface changing unit 400 is completely mounted, the operation unit 615 is released (even if a finger or the like is released from the operation unit 615). ), The lever member 610 (specifically, the locking claw portion 617) is held in the unlocking position by the upright portion 354 of the support rail 300 (see FIG. 25). When the lever 610 is operated, the lever member 610 is not held at the unlocking position, and the lever member 610 is returned to the locking position when the operation unit 615 is released.

  In a configuration in which the lever member 610 is not held at the unlocking position, when the surface changing unit 400 is pulled out from the housing 11, the lever member 610 is operated and held in the state as it is. The housing 410) needs to be pulled out. In the present embodiment, two lever members 610 are provided on the left and right, and even if an unauthorized person operates the lever member 610 with an unauthorized tool such as a wire, the lever member 610 is operated with the wire or the like. Therefore, it is difficult to further pull out the surface changing unit 400. Therefore, unauthorized withdrawal can be suitably suppressed.

  Incidentally, as in the case described above, even if the lever member 610 is not held at the unlocking position, the front door 12 and the inner door may be used when the hall manager or the like pulls out the surface changing unit 400. 700 can be opened without problems. That is, even if the act of opening both doors 12 and 700 gathers the attention of the surroundings, the act itself is not damaging, so there is no inconvenience in the act of opening both doors 12 and 700. In a state where both doors 12 and 700 are opened, the left and right lever members 610 are respectively operated and held with both hands, and the lever member 610 can be pulled forward to pull out the surface changing unit 400, thus ensuring workability. .

  As described above, when the lever member 610 (specifically, the operation unit 615) is provided inside the space defined by the inner casing 410 and the inner door 700 and is not held at the unlocking position, When the surface changing unit 400 is removed, the work is performed in a state where the inner door 700 is opened. In such a case, it is desirable that the open / close base end shaft of the inner door 700 is provided on the open free end side of the front door 12 as shown in the present embodiment. Thereby, when removing the surface changing unit 400, the restriction | limiting of the open angle of the inner side door 700 is suppressed, and it becomes possible to suppress the problem of being caught with the front door 12 grade | etc.,.

  (E) In the above-described embodiment, the lever member 610 is provided with the operation portion 615 that can be operated with a finger, and the operation portion 615 is unlocked by operation. However, this may be changed. For example, it is configured to release the lock by moving the surface changing unit 400 in a specific direction among up and down, left and right, and front and rear. More specifically, in the state in which the surface changing unit 400 is completely mounted, that is, in the locked state between the lever member 610 (specifically, the locking claw portion 617) and the upper guide portion 350a, for example, the front portion of the surface changing unit 400 It is good to set it as the structure which can cancel | release latching by lifting up. It is preferable that the lever member 610 is held at the unlocking position even after the chamfering unit 400 is lifted and unlocked and the chamfering unit 400 is lowered. In such a case, it is not necessary to pull out the surface changing unit 400 in the lifted state after lifting and releasing the surface changing unit 400, and an increase in work load can be avoided. It should be noted that the unlocking operation direction and the operation stroke of the display unit 400 may be set so that the locked state is not released when the display unit is slightly shaken.

  (F) In the above embodiment, as shown in FIG. 22 and the like, the rotation direction (operation direction) of the lever member 610 is configured to be substantially parallel to the side plates 11 d and 11 e of the housing 11. The lever member may be changed so that the rotation direction (operation direction) of the lever member intersects with the side plates 11 d and 11 e of the housing 11. More specifically, instead of a configuration in which the rotation center axis of the lever member 610 is substantially perpendicular to the side plates 11 d and 11 e of the casing 11, for example, the rotation center axis of the lever member 610 is the top of the casing 11. It is good to set it as the structure perpendicular | vertical or substantially perpendicular | vertical with respect to the board 11a.

  (G) In the above embodiment, as described above, the lever member 610 is configured to rotate in parallel with the side plates 11d and 11e of the housing 11, but this is changed so that the unit side locking tool is the side plate 11d. , 11e may be configured to slide in parallel. More specifically, a guide rail or a guide groove may be provided in the inner housing 410 so that the unit-side locking tool slides along the guide rail or the like.

  (H) In the above embodiment, the plate spring 631 as the “biasing member” is configured to maintain the locking state between the locking claw portion 617 of the lever member 610 and the upper guide portion 350a of the support rail 300. . It is also possible to change this as follows. That is, instead of using the elastic force of the leaf spring 631 to maintain the locked state, the locked state may be maintained using the weight of the lever member 610. For example, in the lever member 610, the weight balance between the locking claw portion 617 provided on the support shaft 613 and the operation portion 615 side is set so that the locking claw portion 617 side becomes heavy, and the locked state is set by its own weight. May be maintained. Thereby, the number of parts can be reduced.

  (I) In the above embodiment, the support rails 300 are provided on the left and right side plates 11d and 11e of the housing 11, and the surface changing unit 400 is mounted on the left and right support rails 300. It may be changed as follows. That is, the inside of the housing 11 may be divided into upper and lower portions by a partition plate, and the surface changing unit 400 may be mounted on the partition plate. In this case, the partition plate is provided between the left and right side plates 11 d and 11 e of the housing 11.

  (J) In the above embodiment, the support rail 300 (specifically, the lower guide portion 320) and the slide rail 510 (specifically, the roller 540) are brought into point contact in the low friction section, and the support rail 300 ( Specifically, the lower guide portion 320) and the slide rail 510 (more specifically, the supported portion 512) are in surface contact, but this is changed as follows.

  For example, while the support rail 300 and the slide rail 510 are held in a surface contact state in both the low friction section and the high friction section, the support rail 300 and the slide rail are particularly configured in the low friction section. The surface roughness of at least one of 510 is relatively reduced, and the surface roughness of at least one of the support rail 300 and the slide rail 510 is relatively increased in the high friction section. In other words, by reducing the surface roughness of the parts that contact each other in the low friction section and increasing the surface roughness of the parts that contact each other in the high friction section, the optimum friction resistance in consideration of work load and braking force is given. can do. In addition, about the support rail 300 and the slide rail 510, it is good to give a difference in surface roughness by surface processing or surface treatment.

  Further, the support rail 300 and the slide rail 510 may be in line contact in the low friction section, and the support rail 300 and the slide rail 510 may be in surface contact in the high friction section. Specifically, instead of providing the slide rail 510 with the roller 540, the slide rail 510 is provided with a protrusion protruding downward from the slide rail sliding surface 512a and having a tapered tip, and this protrusion Is configured such that the tip of the line contacts the lower guide portion 320 (horizontal portion 321) of the support rail 300 in line. Thereby, in the low friction section, it can be set as the line contact state in which the tip of the ridge part and the horizontal part 321 are in line contact, and in the high friction section, it can be in the surface contact state as in the above-described embodiment. The difference can be made.

  “Line contact” means that when the surface changing unit 400 (inner housing 410) moves, the contact part in the unit moving direction is linear, and the contact part in the direction orthogonal to the unit moving direction is dotted. It means that. By the way, it is assumed that the contact part spreads due to force such as weight (the tip of the ridge part is crushed), but when the contact part in the direction orthogonal to the unit moving direction spreads due to the weight in this way, “line contact” To be included.

  (K) In the above-described embodiment, the portion where the support rail 300 of the housing 11 and the slide rail 510 of the surface changing unit 400 are in contact with each other is provided with a low friction portion and a high friction portion. You may change this as follows. That is, the housing 11 is provided with another housing side contact member (a member other than the support rail 300) that contacts the surface changing unit 400 (for example, the inner housing 410), and the housing side contact member and the surface changing unit 400 are configured. It is good also as a structure which provides the site | part which becomes low friction, and the site | part which becomes high friction in the part which the inner side housing | casing 410 which contacts.

  For example, a housing side contact member that extends back and forth and contacts the inner housing 410 is provided on the inner surface of at least one of the side plates 11d and 11e and the top plate 11a of the housing 11, and the inner housing is connected to the housing side contact member. Two high and low friction sections (regions) that produce different frictional resistances with the body 410 may be set. In this case, by applying a surface treatment such as coating to a portion of the inner casing 410 (specifically, each plate portion 410a, 410d, 410e) and the casing-side contact member that are in contact with each other, high and low friction sections having different frictional resistances are formed. It can be easily realized.

  (L) In the above-described embodiment, the reel device 650 is mounted on the inner housing 410. However, the reel device 650 may be mounted on a frame-like support by changing the reel device 650. Further, although the inner casing 410 is made of synthetic resin, this material may be changed and made of metal. In addition, it is also possible to mount the reel device 650 on a metal frame-shaped support body by combining the above configurations.

  (M) In the above embodiment, the liquid crystal display device 711 as the “auxiliary display device” and the display control device 730 as the “sub control device” are mounted on the inner door 700 side of the surface changing unit 400. However, it is good also as a structure which changes this and mounts the display control apparatus 730 in the inner side housing | casing 410 side of the surface change unit 400. FIG. Since the display control device 730 is unique for each model and needs to be replaced in accordance with the model change, the liquid crystal display device 711 may be used regardless of the model change, and thus is not necessarily replaced. . A liquid crystal display device 711 is provided on the inner door 700 that is detachably provided on the inner housing 410, and the display control device 730 is provided on the inner housing 410 that is an exchange target of model change. Thereby, the liquid crystal display device 711 can be reused together with the inner door 700.

  (N) In the above embodiment, the “auxiliary display device” is provided with the liquid crystal display device 711 (so-called donut-type liquid crystal device) that is substantially the same size as the front surface of the inner door 700 and has a rectangular ring shape. . That is, a liquid crystal display device having a size smaller than the front surface of the inner door 700 may be provided. For example, the liquid crystal display device may be arranged on either the top or bottom or the left or right of the reel device 650. Further, as the auxiliary display device, a configuration other than the liquid crystal display device, for example, a dot matrix display or the like, or a configuration without the auxiliary display device may be employed.

  (O) In the above embodiment, the surface changing unit 400 includes the inner door 700. However, it is possible to change the surface changing unit 400 so that the surface changing unit 400 does not include the inner door 700. In this case, the front door 12 may be configured to include the liquid crystal display device 711 and the display control device 730.

  (P) The front door 12 provided in the housing 11 so as to be openable and closable may be constituted by an upper door and a lower door which are divided into two parts in the vertical direction. In this case, the opening of the housing 11 is closed with an upper door and a lower door that are divided into upper and lower parts, and the upper door and the lower door are attached to the housing 11 in a state that can be opened and closed. Moreover, it is good also as a structure which attaches an upper door to the inner side housing | casing 410, and attaches a lower door to the housing | casing 11 so that opening and closing is possible.

  (Q) In the above embodiment, of the housing connectors 811 and 812 and the surface changing connectors 841 and 842, only the surface changing connectors 841 and 842 provided on the surface changing unit 400 side are movable connectors, and the housing 11 side. Although the housing connectors 811 and 812 provided in FIG. 4 are fixed connectors, this may be changed and both the face change connectors 841 and 842 and the housing connectors 811 and 812 may be movable connectors.

  Further, the surface change connectors 841 and 842 may be fixed connectors, and the housing connectors 811 and 812 may be movable connectors. The back plate 410c of the inner housing 410 is formed with a housing recess 442 for housing the housing connectors 811 and 812 and the surface changing connectors 841 and 842 in a state where the inner housing 410 is completely attached (FIG. 14). In this way, by fixing the surface changing connectors 841 and 842, the size of the housing recess 442 can be made appropriate. That is, as compared with the case where the surface changing connectors 841 and 842 are movable connectors, it is not necessary to consider the amount of movement of the connector, so the minimum necessary size with respect to the connectors 811, 812, 841 and 842 in the coupled state Thus, the receiving recess 442 can be formed. Thereby, the fraud performed with respect to the connector 811,812,841,842 can be suppressed suitably.

  (R) In the above embodiment, the surface changing connectors 841 and 842 have the insertion portions 841a and 842a, and the housing connectors 811 and 812 have the insertion ports 811a and 812a. The surface change connectors 841 and 842 may have an insertion port, and the housing connectors 811 and 812 may have an insertion portion.

  (S) In the above embodiment, as shown in FIG. 28, the circular hole 846 as the “opening” is configured so that the opening cross section has a circular shape, but this is changed to form a rectangular shape. May be. However, in this case, at least the upper part of the “opening” is in a state where the inner surface of the “opening” is in contact with the outer surface of the shaft 849 when the surface changing connector 841 is lowered by its own weight with respect to the shaft 849. It is desirable to provide a guiding portion for guiding to the same location. By providing the guiding portion in this manner, the connectors are separated from each other, and variations in the position of the surface changing connector 841 can be reduced. For example, the rectangular shape may be formed so as to protrude upward.
