  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: “In a slot machine that is a kind of gaming machine, a reel device, a medal payout device, various control devices (including the main board), a power supply device, etc. are mounted inside the case, The front door that can be opened and closed is provided with an auxiliary display device, medal insertion device, start lever, stop button, etc. When playing a game, the player inserts a medal (or bet operation) and starts each time the game is played. When the operation is performed, the reel of the reel device starts rotating, the symbols attached to the outer peripheral surface of the reel device are variably displayed through the display window, and various effects are displayed by the auxiliary display device. Later, the reel is stopped when the stop button is pressed by the player or a predetermined time elapses. The player is given a profit state, such as a medal payout, according to the stop pattern visually recognized through such a slot machine. Reported fraudulent acts such as causing unauthorized equipment to enter and causing the control device to malfunction, or causing the sensor to detect the insertion of medals to malfunction and repeating the game without actually inserting medals On the other hand, a slot machine is disclosed in which a fraud prevention plate is attached to the inside of a wall plate constituting the housing so as to extend from the front end edge to the front of the gaming machine, and the fraud is suppressed. In this case, even if it is attempted to intrude unauthorized tools through the gap between the housing and the front door, the intrusion prevention plate will be prevented from entering the housing. Play Along with the diversification of contents, in order to provide players with more innovative and interesting games, the model change of gaming machines tends to be done in a short cycle. A separation type slot machine has been proposed in which a display unit (replacement unit) is configured by being mounted on a frame-shaped support, and the display unit is detachably provided inside the housing (for example, Patent Document 1). As for the background art, “However, in the configuration including the display unit as described above, if the anti-tamper plate is attached to the housing as described above, the unit is prevented from tampering when the display unit is replaced. If the anti-tamper plate is deformed or displaced, the anti-tamper function of the anti-tamper plate may be reduced. In the lot machine, since it is necessary to attach a fraud prevention plate to the housing, for example, when the slot machine is manufactured, there is a possibility that the fraud prevention plate is not attached due to an error. Furthermore, in order to attach the anti-tamper plate to the housing, it is necessary to use a fixing tool such as a screw. In this case, the number of parts of the slot machine is increased, and further, the number of processes in manufacturing the slot machine is increased. I'm concerned that it might cause it. This invention has been made with a problem to be solved.

Means 1. A housing (housing 11) that is open to the front of the gaming machine and has left and right side plates (left side plate 11d, right side plate 11e), and a top plate (top plate 11a) and a bottom plate (bottom plate 11b) passed to each side plate; ,
An overhanging portion (an overhanging portion) that is provided so as to close the front opening of the housing and that protrudes in contact with or close to the front end surfaces of the left and right side plates, the top plate, and the bottom plate of the housing on the periphery. 15) a front door (front door 12),
A pattern display device (reel device 650) that has a plurality of rotating bodies (reels 655 to 657) in which a plurality of types of patterns are arranged in the circumferential direction and displays the patterns by rotating these rotating bodies is provided in the unit main body (inside A display unit (replacement unit 400) mounted on the housing 410),
In a gaming machine in which the display unit is detachably mounted inside the housing,
The unit main body has side wall portions (left side plate portion 410d, right side plate portion 410e) on both left and right sides, and the display unit is arranged in a state where the side wall portions of the unit main body face each other along both side plates of the housing. Attached to the housing,
The front end edge of at least one of the side wall portions of the unit main body protrudes from the front end surface of the side plates of the housing to the front of the gaming machine over substantially the entire area, and the inside of the inner peripheral edge portion of the overhang portion of the front door A gaming machine characterized by having a configuration located in

  In the gaming machine of means 1, a display unit in which the picture display device is mounted on the unit main body is configured to be detachable from the inside of the housing. The unit main body has left and right side wall portions, and the both side wall portions are mounted in a state of facing each other along both side plates of the casing. When the display unit is completely mounted, at least one of both side walls of the unit main body protrudes forward of the gaming machine from the front end of each plate of the housing in almost the entire area of the front end edge (that is, at the same height). When compared in the horizontal cross section, it protrudes ahead of the gaming machine from the front end of each plate), and is configured to be located inside the inner peripheral edge of the overhanging portion of the front door. For this reason, a gap (hereinafter also referred to as a boundary portion) between the front end surface of the side plate of the housing and the front door is blocked from the inside, and is performed through the gap between the housing and the front door. It is possible to suppress an illegal act such as malfunction of a sensor or the like inside the gaming machine using an unauthorized tool.

  Further, in a state where the side wall portion of the unit main body is opposed along the both side plates of the housing, the side wall portion and the side plate may be in contact with each other, and there is a space (gap) between the side wall portion and the side plate. May be. In particular, when a space is provided between the side plate and the side wall, even if an unauthorized tool is inserted from the gap between the side plate of the housing and the front door, the approach direction of the unauthorized tool is set to a predetermined direction by the side wall. It is possible to guide. For example, when it is desired to guide the illegal equipment to the rear of the gaming machine, the gap from the side plate of the housing is increased at the rear of the side wall (configuration that is inclined to the inside of the housing on the back side of the housing). That's fine.

  As described above, since the side wall portion of the unit main body plays a role as a shielding portion that shields the gap, it is not necessary to separately provide a shielding member for shielding the gap. That is, for example, unlike a conventional gaming machine in which a shielding member or the like is provided on the inner surface of both side plates of the housing so as to extend forward from the front edge, the display unit hits the shielding member when the display unit is attached or detached. Thus, it is possible to avoid the disadvantage that the shielding member is deformed or displaced.

  Furthermore, since the shielding part (the side wall part of the unit body) is configured as a part of the unit body constituting the display unit, the shielding member is not attached unlike the configuration in which the shielding member is provided separately. It can be suitably prevented that the gaming machine is installed in a game hall or the like in the state, or that the inconvenience of forgetting to attach the shielding member when the display unit is replaced. Further, it is possible to shield the gap between the housing and the front door without causing an increase in the number of parts of the gaming machine and an increase in the number of processes when manufacturing the gaming machine. As described above, it is possible to simplify the configuration and to reliably obtain a desired fraud suppression effect.

  The side wall portion may be provided adjacent to at least a boundary portion between the housing and the front door. For example, the unit body is provided with a side part (plate shape, frame shape, etc.) that is equal to or larger than the picture display device in side view of the gaming machine, and a part of the front side is around the boundary between the housing and the front door It is also possible to form a wall shape at the site.

  Note that “the state in which both side wall portions face each other along both side plates of the housing” means that the side wall portion of the unit main body is in contact with the side plate of the housing, or that the side plate portion and the side plate are kept close to each other. Indicates the state. The side plate and the side wall (specifically, the outer surface) may be parallel or may not be parallel. For example, it includes a case where at least one of the outer surface of the side wall portion and the inner surface of the side plate has irregularities.

  In addition, “substantially the entire area” means that the unit side component (for example, door support) is attached to a part of the front edge of the side wall of the unit body, or interference with other components (for example, front door) is avoided. It is shown that the entire region of the front end edge of the side wall portion includes a state in which the front end edge does not completely protrude from the side plate.

  In this specification, “detachable” means that the object to be attached / detached is not fixed by a fixing tool such as a screw or a fixing means such as welding, and is configured to be easily attached / detached.

Mean 2. The unit main body has an upper wall portion (top plate portion 410a) above the both side wall portions in addition to the left and right side wall portions, and the upper wall portion is on the top plate (top plate 11a) of the casing. A gaming machine in which the unit main body is mounted on the casing in a state of being opposed to each other,
A structure in which substantially the entire front end edge of the upper wall portion of the unit body protrudes forward of the gaming machine from the front end surface of the top plate of the housing and is located inside the inner peripheral edge portion of the protruding portion of the front door. The gaming machine according to means 1, which is characterized by the above.

  According to the means 2, the unit main body has the upper wall portion and is mounted in the housing in a state where the upper wall portion is opposed along the top plate of the housing. The upper wall portion of the unit main body extends in front of the gaming machine from the front end portion of the top plate of the housing in a state where the unit main body is mounted, and is located inside the inner peripheral edge portion of the protruding portion of the front door. It is configured. For this reason, the clearance gap between the front-end surface of the top plate of a housing | casing and a front door is interrupted | blocked from an inner side, and the fraudulent act performed through the clearance gap can be suppressed.

  Means 3. 3. The gaming machine according to means 1 or 2, wherein the unit main body is configured to have a casing shape opened forward.

  According to the means 3, the unit main body has a casing shape. For this reason, even if an unauthorized tool or the like is inserted through a gap (boundary portion) between the housing and the front door, access to the inside of the unit body can be suitably suppressed. In particular, according to the combination with the means 2 (a configuration in which the upper wall portion of the unit main body is mounted along the top plate of the casing), the unit main body forms a casing shape, along the both side plates and the top plate of the casing. Therefore, it is possible to shield at the left and right upper corners of the boundary between the housing and the front door. Therefore, it is possible to expect an excellent suppression effect against fraud in the left and right upper corners.

  Means 4. Any one of means 1 to means 3, wherein each wall portion of the unit main body is provided with a shielding portion (for example, an attachment base portion 460) facing the boundary portion between the housing and the front door at equal intervals. The gaming machine described in Crab.

  In order to shield the boundary between the housing and the front door from the inside of the housing, like the means 4, it faces the boundary between the housing and the front door (that is, the side plate of the housing) at equal intervals. It is good to provide the shielding part to perform in each wall part of a unit main body. Thereby, a practically preferable configuration can be realized.

  Means 5. The gaming machine according to any one of means 1 to means 4, wherein a part of the front side of the unit main body is accommodated in a space portion formed by a protruding portion of the front door.

  Front doors tend to be opened and closed frequently for maintenance (power on / off, medal replenishment, etc.), etc. As described above, by providing an overhang at the periphery of the front door, the rigidity of the door itself is increased. It becomes possible to raise. Further, in the configuration in which the overhang portion is provided, the distance between the pattern display device and the front side of the front door is shortened by adopting a configuration in which a part of the unit main body is accommodated in the space in the overhang portion. Visibility is improved. That is, it is possible to ensure the visibility of the picture display device while improving the rigidity of the front door by providing the overhanging portion on the front door and moving the picture display device forward.

  Means 6. A restriction portion or a restriction member (for example, guide rib 470 and boxes 480, 490) for restricting the side movement of the unit main body when the unit main body is attached / detached, and an inner surface of the side plate of the housing and an outer surface of the side wall portion of the unit main body. A gaming machine according to any one of means 1 to means 5 provided in at least one of the above.

  According to the means 6, at the time of attaching / detaching the unit main body, a restricting portion or a restricting member for restricting the side movement of the unit main body is provided on at least one of the side plate of the housing and the side wall portion of the unit main body. For this reason, it can suppress that a unit main body shifts to right and left inside a housing | casing, and can improve workability | operativity at the time of attaching / detaching a unit main body (display unit). In addition, the deviation between the left and right sides of the unit main body after the unit main body has been installed increases the clearance between the side plate of the housing and the side wall of the unit main body at either the left or right boundary part. Can be suppressed. Even if an attempt is made to create a portion where it is easy to insert a fraudulent tool by causing a position shift of the unit main body by shaking the gaming machine main body, the movement of the unit main body to the left and right is restricted as described above. Therefore, this can be prevented.

  Mean 7 A support member (support rail 300) that movably supports the unit main body within the housing is provided in the housing, and the display unit is located behind the housing in a state where the unit main body is in contact with the support member. The gaming machine according to any one of means 1 to 6, wherein the display unit is mounted on the casing by moving to the side.

  According to the means 7, the support unit is provided in the casing, and the display unit is attached to the casing by moving the display unit to the back side of the casing in a state where the unit main body is in contact with the supporting member. The configuration. When mounting the unit main body, it is possible to suppress the incline in the left-right direction by pushing the unit main body on the support member, and to suppress the inconvenience that the side plate on the housing side and the side wall on the unit main body interfere with each other. . In particular, in combination with the means 6 (configuration provided with a restricting member that restricts the movement of the unit body in the left-right direction), in addition to the left-right inclination of the unit body, it is also possible to restrict the left-right positional deviation. The mounting operation can be made easier.

Means 8. Inclining the side wall of the unit main body from the front side of the case toward the back side toward the inside of the case,
The side wall portion is provided with a ridge portion as the restricting portion extending in the mounting direction of the display unit, and the standing amount of the ridge portion on the back side of the housing is set as the rising amount on the near side of the ridge portion on the housing side. The gaming machine according to means 7, wherein the gaming machine is larger than the above.

  According to the means 8, the configuration in which the side wall portion of the unit main body is inclined toward the inner side of the housing (center side of the housing) from the front side of the housing toward the back side, that is, the interval between the side wall portions of the unit main body is the housing. It became the structure which becomes small in the body depth side, and provided the protrusion part in those side wall parts. By adopting a configuration in which the protruding amount of the protruding portion is increased on the rear side, when the display unit is mounted on the housing, the rear end portion of the protruding portion hits the housing or the component on the housing side. In addition, it is possible to easily absorb the impact by deforming (for example, elastically deforming) the protrusions themselves. In addition, by making the ridges large, it is possible to ensure the function of restricting the positional deviation of the display unit even if the ends thereof are slightly crushed or scraped.

  In addition, by reducing the distance between the side wall portion and the side plate of the housing on the front side of the unit main body, a space in which the unauthorized tool can freely move when the unauthorized tool or the like enters is reduced.

  For example, the side wall portion may be formed in a slope shape in which the distance from the side plate of the housing gradually increases or decreases, or in a step shape in which the distance from the side plate in the housing gradually increases or decreases.

  Means 9. A braking section (surface contact section L2) that suppresses movement of the display unit 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. The gaming machine according to means 7 or means 8 characterized.

  According to the means 9, a braking section that suppresses the movement of the display unit 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 display unit 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. For this reason, when the display unit moves to the mounting completion position, it is possible to reduce the impact caused by the collision with the housing side.

  If the display unit is pushed into the housing vigorously, when the display unit moves to the mounting completion position, the display unit bounces back, and the display unit mounting completion position may vary. In the present invention, the boundary portion between the front door and the housing is shielded from the inside by the side wall portion of the unit main body, etc., and when the mounting completion position of the display unit varies as described above, the boundary portion is sufficiently shielded. It is assumed that this will not be done. However, by braking the display unit in the braking section before the installation of the display unit is completed, it is possible to suppress the inconvenience that the display unit rebounds from the installation completion position, and shielding the boundary portion between the front door and the housing. Can be ensured.

  Further, when the display unit moves to the mounting completion position, there is a possibility that the display unit will bounce back due to a reaction and be displaced to the front side of the gaming machine. When the front door is closed with the display unit displaced in front of the gaming machine in this way, there is a concern that the front door and the front portion of the display unit (for example, the inner door or the auxiliary display device) may interfere with each other. However, as described above, it is possible to avoid interference between the front door and the display unit by braking the display unit.

  Means 10. 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. The gaming machine according to means 7 or 8, characterized in that it is provided on the back side.

  According to the means 10, there are provided two sections (low friction section and high friction section) having different frictional resistance between the unit body and the support member or the housing side contact member when the unit body is mounted on the housing. It has been. 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 wearing, the frictional resistance is increased, thereby preventing the display unit from moving. For this reason, when the display unit moves to the mounting completion position, it is possible to reduce the impact caused by the collision with the housing side.

  If the display unit is pushed into the housing vigorously, when the display unit moves to the mounting completion position, the display unit may bounce back and vary the mounting completion position of the display unit. In the present invention, the boundary portion between the front door and the housing is shielded from the inside by the side wall portion of the unit main body, etc., and when the display unit mounting completion position varies as described above, the boundary portion is sufficiently shielded. It is assumed that this will not be done. However, by braking the display unit in the braking section before the installation of the display unit is completed, it is possible to suppress the inconvenience that the display unit rebounds from the installation completion position, and shielding the boundary portion between the front door and the housing. Can be ensured.

  Further, assuming that the display unit is braked by using a buffer member such as a spring or rubber when the display unit moves to the mounting completion position, and the buffer member is deformed, the display unit is repelled by the buffer member. There is a possibility that it will be bounced back and be displaced to the front side of the gaming machine. When the front door is closed with the display unit displaced in front of the gaming machine in this way, there is a concern that the front door and the front portion of the display unit (for example, the inner door or the auxiliary display device) may interfere with each other. The As described above, by braking the display unit by friction, when the display unit reaches the mounting completion position, the gaming machine can be configured to have no energy to move the display unit. Positioning accuracy can be improved. Therefore, it becomes easy to avoid interference between the front door and the display unit.

  Means 11. The gaming machine according to claim 10, wherein the low friction section and the high friction section are provided continuously.

  According to the means 11, 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 in, when the display unit passes through the boundary between the low friction section and the high friction section, the display unit approaches the arrangement completion position and is in the section to be braked. It becomes possible to suggest. Thereby, the dispersion | variation in the installation completion position of a display unit can be suppressed, and the shielding of the boundary part of a front door and a housing | casing can be made more reliable.

Means 12. The support member is configured to contact the unit main body in a section in which the display unit moves to a mounting completion position when the display unit is mounted to the housing.
The gaming machine according to claim 11, wherein the low friction section and the high friction section are provided so that frictional resistance generated between the support member and the unit main body is different from each other.

  According to the means 12, 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, it is possible to improve the reusability of the braking member.

  Means 13.

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. 8). 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. In addition, 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. 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 forward 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 such 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 projection 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 the 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.

(Description of the surface changing unit 400)
Next, the structure of the surface changing unit 400 mounted inside the housing 11 will be described. 13 is a perspective view of the surface changing unit 400 as viewed obliquely from above, FIG. 14 is a perspective view showing the rear structure of the surface changing unit 400, FIG. 15 is a front view of the surface changing unit 400, and FIG. 17 is a right side view of the surface changing unit 400, FIG. 18 is a perspective view showing an open state of the inner door 700 of the surface changing unit 400, and FIG. 19 is an exploded view of the surface changing unit 400 for each main component. It is a disassembled perspective view shown. In the following description of the surface changing unit 400, directions such as up, down, left and right are described based on the state of FIG. 15 unless otherwise specified.

  The main surface changing unit 400 mainly includes a box-shaped inner casing 410 whose front side is open, a reel device 650 disposed inside the inner casing 410, and a right edge of the opening of the inner casing 410. 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. A columnar protrusion 436 is provided at the approximate center of the front surface of each protrusion 435 so as to extend to the front side. 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 at the time.

  As shown in FIG. 14 and FIG. 16 (a rear perspective view of the surface changing unit 400, a rear view of the surface changing unit 400), a horizontally long accommodating recess 442 is formed in the approximate center of the back plate portion 410c. A horizontally long hole 443 is formed in the bottom of the housing recess 442 so as to penetrate inside and outside. Details of the housing recess 442 and the hole 443 will be described later.

  The left side plate portion 410d will be described with reference to FIGS. 18 and 20 (a front perspective view of the surface changing unit 400, a front perspective view of the inner housing 410). A rectangular opening 450 is formed in the upper portion of the left side plate portion 410d so as to penetrate inside and outside. A rectangular opening 451 is also formed below the opening 450 so as to penetrate inside and outside. In the following description, the upper opening is referred to as “upper opening 450”, and the lower opening is referred to as “lower opening 451”. An accommodation recess 452 that is connected to the back plate 410c and the bottom plate 410b and is recessed inward is formed in the lower part of the left side plate 410d (below the lower opening 451).

  Next, the right side plate portion 410e will be described with reference to FIGS. A mounting base portion 460 extending along the front edge of the right side plate portion 410e is formed outside the right side plate portion 410e. The attachment base 460 constitutes an attachment part of the door support fitting 740. In addition, since it is difficult to confirm the attachment base 460 in FIGS. 13 to 19, refer to the perspective view of FIG. A concave portion 462 connected to the back plate portion 410c is formed in the upper portion of the right side plate portion 410e. More specifically, the recess 462 has a shape that can avoid interference with an external terminal (not shown) provided on the inner upper portion of the right side plate 11e of the housing 11 when the surface changing unit 400 is mounted on the housing 11. It is formed with. A side opening 463 that penetrates into and out of the inner casing 410 is provided at the bottom of the recess 462, and a later-described relay provided inside the inner casing 410 with the external terminal via the side opening 463. The substrate 790 can be connected.

  At substantially the center of the inner surfaces of the side plate portions 410d and 410e in the vertical direction, unillustrated protrusions extending in the front and rear directions along the same side plate portions 410d and 410e are provided on the left and right sides.

  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.

  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.

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 in the bearing hole portion 612, and a cylindrical portion 614 is provided below the lever member 610 so as to cover the exposed portion. 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. Protection is possible. 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.

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 collar portion 617 is locked to the notch 352, the operation portion 615 of the lever member 610 is tilted forward against the urging 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 casing 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 it can also 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 bar bracket receiving metal. 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 caught 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 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, and supports corresponding to these bearing portions 780 and 781 are provided. A support bracket (not shown) having a 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 reapplied. It can be confirmed whether or not the main control board is 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 attached again. 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 connection mechanism includes case connectors 811 and 812 provided on the case 11 side and surface change connectors 841 and 842 provided on the surface change unit 400 side.

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 base plate 445 is provided with leg portions 446 extending forward to attach the printed circuit board 813 to the left and right ends of the printed circuit board 813. The printed circuit board 813 is connected to the front surface of the base board 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. 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 guiding inclined surface 827 is formed to be inclined, and details of the guiding 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 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 overhanging 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 constituting 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 included in the screw 848. 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 the surface changing unit 400 is replaced. 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, the guide inclined surface 827 of the support member 819 and the lower guide inclined surface 860 are provided so as to be continuous. 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 °. When 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 drawing 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.

  As shown in FIG. 24 and the like, the inner housing 410 (the surface changing unit 400) projects forward from the opening of the housing 11 in a state of being mounted on the housing 11. For this reason, in a state where the front door 12 is closed to the housing 11, the boundary portion between the housing 11 and the front door 12 is shielded from the inside by the inner housing 410. For this reason, it is possible to suppress an illegal act performed via the boundary portion such as malfunctioning of a sensor or the like inside the gaming machine using an illegal tool such as a wire. For example, it is possible to suppress an illegal act of erroneously operating a sensor that detects insertion of a medal with an inserted illegal tool and repeating a game without actually inserting a medal.

  As described above, since the inner housing 410 has a function of shielding the boundary portion between the housing 11 and the front door 12, it is not always necessary to provide a shielding function on the housing 11 side. That is, it is not necessary to increase the size of the door support fitting 200 provided around the opening of the housing 11 for the purpose of shielding the boundary portion, and the protrusion of the door support fitting 200 etc. to the inside of the housing 11 can be reduced. Therefore, when mounting the inner housing 410, it is possible to suppress the inconvenience such as contact with the door support fitting 200 or the like.

  Further, as shown in FIG. 20 and the like, the inner casing 410 has a casing shape. For this reason, even when an unauthorized tool or the like is inserted through a boundary portion between the housing 11 and the front door 12, it is possible to make it difficult to access the inside of the unit main body. In particular, in the present embodiment, since the inner door 700 is attached so as to close the front opening of the inner casing 410, unauthorized access to the inside of the unit main body can be more suitably suppressed.

  Since the main control device 770 is mounted inside the inner housing 410 that makes unauthorized access difficult, the main control device 770 can be suitably protected against unauthorized use. Further, when the main control device 770 is configured to include the reset switch 102 and the setting key insertion hole 103, it is possible to suitably suppress an unauthorized change in setting for adjusting the payout of medals in the gaming machine. .

  The inner casing 410 has a box shape, and has a configuration in which there is no gap between the left and right side plate portions 410d and 410e and the top plate portion 410a. For this reason, it becomes possible to shield even at the left and right upper corners of the boundary portion between the housing 11 and the front door 12, and it is possible to expect an excellent suppression effect against fraud at these corners.

  In a state where the inner housing 410 is completely attached to the housing 11, the boxes 480 and 490 provided in the housing 11 can prevent the inner housing 410 from shifting to the left and right inside the housing 11. In other words, it is possible to prevent the clearance between the side plate of the housing and the side plate portion of the unit body from becoming large at either the left or right of the boundary portion between the housing 11 and the front door 12 due to the bias of the inner housing 410. can do. Even if an attempt is made to create a position where an unauthorized tool can easily enter by causing the positional displacement of the inner casing 410 by, for example, shaking the slot machine 10, the movement of the inner casing 410 to the left and right is as described above. Because it is regulated, this can be prevented.

  Moreover, since the track | orbit at the time of mounting | wearing the inner housing | casing 410 with the boxes 480 and 490 is stabilized, the inner housing | casing 410 inclines or shifts right and left, for example, and the door support provided around the opening of the housing | casing 11 The inconvenience of hitting the metal fitting 200 or the like can be suppressed.

  Further, as the inner housing 410 is mounted, the lever member 610 on the inner housing 410 side and the support rail 300 (specifically, the notch 352) on the housing 11 side are brought into a locked state, so that the movement of the inner housing 410 is completed. Limited. As a result, for example, it is possible to suppress the inconvenience that a positional shift occurs in the inner housing 410 after completion of the mounting. If a cheating person tries to twist out a gap for inserting a fraudulent tool or the like and shakes the slot machine 10 or the like, the inner casing 410 is shifted so that the side plates 410d and 410e of the inner casing 410 are moved away from the casing 11. Even if it is a case where it is going to keep away from the boundary part with the front door 12, since the movement of the inner side housing | casing 410 is suppressed, this can be prevented.

  Note that the inner casing 410 is shifted to the locked state by pushing the inner casing 410 into the mounting completion position. In other words, since a separate operation for shifting to the locked state is not required, an inconvenience that the deterring power against fraud is reduced by the operator forgetting the operation is less likely to occur.

  As a locking device for the front door 12, the metal fittings 231 and 232 are provided on the front door 12, and the metal fittings 220 (specifically, the metal fitting receiving portions 221 and 222) are provided on the housing 11. The upper hook receiving portion 221 is provided in a portion of the left side plate 11 d of the housing 11 that faces the left side plate portion 410 d of the inner housing 410. For this reason, it is difficult to access the cognate receiving portion 221 from the side of the slot machine 10. Even if a fraudulent person inserts a fraudulent tool such as a wire from the boundary between the housing 11 and the front door 12 and attempts to gain unauthorized access to the hook receiving portion 221, this may be difficult. it can.

  Each of the metal fittings 231 and 232 can be independently rotated to the locking position, and the metal fittings 231 and 232 are connected by a connecting member and moved in conjunction only with the operation key K of a hall manager or the like. The configuration is as follows. For this reason, for example, even if the lower metal fitting 232 is unlocked for the purpose of unauthorized opening of the front door 12, it is possible to suppress the inconvenience that the upper metal fitting 231 is unlocked in conjunction therewith. Since unauthorized unlocking of at least the upper metal fitting 231 is difficult, unauthorized opening of the front door 12 can be suitably suppressed while locking up the front door 12 at two upper and lower positions to suppress the lifting. .

The pivot shaft portions of the two metal fittings 231 and 232 are provided in the vicinity of the boundary portion between the front door 12 and the housing 11. As a result, it is difficult to access other than the pivot shaft portion of the metal fittings 231 and 232 through the boundary portion. For example, even when an unauthorized person inserts a fraudulent tool such as a wire from the boundary portion between the housing 11 and the front door 12 to access the metal fittings 231 and 232, the access portion is limited to the vicinity of the rotating shaft portion. The Even if an attempt is made to move the saddle fittings 231 and 232 to the unlocked position in a state where the unauthorized tool is hooked on the saddle fittings 231 and 232, a force acts on a position near the fulcrum of the saddle fittings 231 and 232, It becomes difficult to rotate 232. Therefore, it is not easy to separate the metal fittings 231 and 232 from the collar receiving portion, and unauthorized release of the locked state can be more suitably suppressed.
For this reason, even if an unauthorized person attempts to insert a fraudulent tool such as a wire through the gap at the boundary between the housing 11 and the front door 12 and hook it on the metal fittings 231 and 232 to move it to the unlocked position, Other than the access to the moving shaft portion or the vicinity thereof is difficult. That is, even if it tries to rotate the metal fittings 231 and 232 in the position near a fulcrum, it is difficult to transmit sufficient force, and it is not easy to separate the metal fittings 231 and 232 from the collar receiving portions 221 and 222. . Therefore, the illegal release of the locked state can be more suitably suppressed.

  As shown in FIG. 1 and the like, the front door 12 is provided with a protruding portion 15 that protrudes toward the housing 11 side. Thereby, the rigidity of the front door 12 can be improved. The front door 12 tends to be opened and closed frequently for maintenance (power on / off, replenishment of medals, etc.) and the like. Can be suppressed. Further, by housing a part of the inner housing 410 and the inner door 700 in the overhanging portion 15, the reel device 650 (specifically, reels 655 to 657) and the liquid crystal display device 711 mounted on them are moved forward of the slot machine 10. Visibility from can be ensured. That is, it is possible to achieve both improvement in the rigidity of the front door 12 and ensuring the visibility of the reels 655 to 657 and the like.

  Further, as shown in FIG. 4 and the like, the liquid crystal display device 711 and the display control device 730 are mounted not on the front door 12 but on the inner door 700 of the surface changing unit 400. Thus, weight sharing generated on the front door 12 can be reduced by sharing the weight. When comparing the opening and closing frequency of the front door 12 and the inner door 700 for maintenance or the like, the frequency of the front door 12 is considered to increase. Therefore, by suppressing the increase in the weight of the front door 12 as described above, workability can be improved. Improvement is expected. Furthermore, the variation in the installation of the front door 12 can be reduced by reducing the weight burden of the front door 12. Thereby, it is possible to preferably avoid the disadvantage that the boundary portion between the front door 12 and the housing 11 is expanded.

  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 amount of protrusion from the opening of the housing 11 of the inner housing 410 constituting the surface changing unit 400 is configured to be substantially equal on the left and right at the same height. This may be changed so that one of the left and right protrusions is larger than the other protrusion. Further, as shown in FIG. 24, the protruding amount of each of the left and right side plate portions is configured to gradually increase from above to below, but is not limited to this, and gradually increases from above to below. You may comprise so that it may decrease to the same, and you may comprise so that it may become the same protrusion amount in any height.

  (B) In the above embodiment, as shown in FIG. 10 and the like, the top plate portion 410a of the inner housing 410 (replacement unit 400) does not protrude forward from the opening of the housing 11, and the top plate The reinforcing plate 411 protrudes forward from the opening of the housing 11 with the reinforcing plate 411 attached to the portion 410a. It is good also as a structure which changes this and the top-plate part 410a protrudes ahead rather than an opening part. In addition, the inner housing 410 is mounted so that the top plate portion 410a is along the top plate 11a of the housing 11, but this can be changed as follows. That is, the inner casing 410 may be mounted so that the top plate 11a and the top plate portion 410a are separated from each other. In this case, for example, a speaker or the like may be provided separately between the top plate 11a and the top plate portion 410a. By providing a total of four speakers at the lower and upper portions of the slot machine 10, it is possible to diversify the production of sound.

  (C) In the above embodiment, as shown in FIG. 13, the reinforcing plate 411, the door support fitting 740, and the rod receiving fitting 750 are provided outside the inner housing 410. You may change this as follows. In other words, the reinforcing plate 411, the door support fitting 740, and the saddle receiving fitting 750 may be provided inside the inner housing 410. In this case, the rigidity around the opening of the inner housing 410 can be easily improved. Further, the reinforcing plate 411, the door support fitting 740, and the saddle receiving fitting 750 may be omitted.

  (D) In the above embodiment, the “unit main body” has a configuration (chassis shape) having an integrated surface structure by mutual coupling of the respective plate portions 410a to 410e, but this is changed as follows. Also good. That is, the unit main body may have a structure (frame shape) having a shaft assembly structure in which the vertical frame member (column) and the horizontal frame member (beam) are connected in a rectangular parallelepiped shape. However, in this case, it is desirable that a shielding plate that shields the boundary portion from the inside corresponding to the boundary portion between the front door 12 and the housing 11 is attached to the unit main body. Further, by combining the surface structure and the shaft assembly structure, it is also possible to have a structure in which only both side portions of the unit main body are plate-shaped and a beam is bridged between the both side portions.

  (E) In the above embodiment, the inner door 700 is mounted in front of the opening of the inner housing 410, but this is changed so that the inner door 700 does not protrude forward from the opening of the inner housing 410. May be. Thereby, it can be set as the structure which the boundary site | part of the inner side housing | casing 410 and the inner side door 700 is not exposed to the side of the slot machine 10 (it is set to the front). That is, the boundary part of the housing 11 and the front door 12 and the boundary part of the inner housing 410 and the inner door 700 do not face the same direction. Even if an unauthorized tool such as a wire is inserted from the boundary between the housing 11 and the front door 12, access to the boundary between the inner housing 410 and the inner door 700 becomes more difficult. Safety against fraud in the body 410 can be improved.

  Further, in this case, the front door 12 is provided with a protruding plate portion extending so as to be opposed to the protruding portion 15 inside the protruding portion 15, and the protruding portion 15 and the protruding plate portion are doubled inside and outside. It is preferable that the front end portions of the plate portions 410a, 410d, and 410e are stored between the protruding portion 15 and the protruding plate portion with the front door 12 closed. By comprising in this way, it becomes possible to suppress invasion of unauthorized tools, such as a wire, more suitably.

  (F) The number of boxes 480 and 490 and the size in the front-rear and up-down directions (excluding the thickness direction on the left and right) are arbitrary. For example, by increasing the number of boxes 480 and 490, the gap (dead space) between the casing 11 (specifically, the side plates 11d and 11e) and the inner casing 410 (specifically, the side plate portions 410d and 410e) can be reduced. It is possible to more appropriately suppress fraud such as an illegal substrate being installed in the dead space.

  In addition, a configuration in which the guide rib 470 is not provided is also possible. However, in this case, since the inclined surface 471 is formed on the guide rib 470 to suppress the hooking to the boxes 480 and 490, as an alternative to this, the side plates of the boxes 480 and 490 are curved inwardly convex. It is desirable to configure so that Thereby, workability | operativity at the time of unit attachment / detachment can be ensured.

  (G) In the above-described embodiment, the support rail 300 is provided separately on the left and right sides of the housing 11 and is configured by separate members. You may change this as follows. That is, you may comprise a support rail by one member. For example, a support member having a flat plate shape may be provided so as to span between both side plates 11 d and 11 e of the housing 11. Thereby, the support function which supports the inner side housing | casing 410 (surface change unit 400) and the reinforcement function which improves the rigidity of the housing | casing 11 can be provided to a support member.

  (H) In the above-described embodiment, the surface changing unit 400 is in a locked state (cannot be taken out) as the surface changing unit 400 is pushed into the housing 11. It may be configured so that the same surface changing unit 400 cannot be taken out by a separate operation after the installation of 400 is completed. For example, a lock metal fitting is provided on the housing 11 side, and a hook metal fitting is provided on the surface changing unit 400 side corresponding to the lock metal fitting, and an operator hooks the hook metal fitting on the lock metal fitting after the mounting of the surface changing unit 400 is completed. By doing so, it may be configured such that the surface changing unit 400 cannot be taken out.

  (I) In the above-described embodiment, the hook metal fitting 220 that closes the front door 12 faces the side plate portion 410e of the inner housing 410 on the right side plate 11e of the housing 11 (opening / closing free end side of the front door 12). Provided in the part. By changing this, it is also possible to provide the hook metal fitting on the top plate 11 a of the housing 11 at a portion facing the top plate portion 410 a of the inner housing 410. However, in this case, it is desirable to provide the hook receiving portion of the hook receiving metal near the open / close free end of the front door in consideration of restraining the floating of the front door 12 from the housing 11 side.

  (J) In the above embodiment, two sets of the hook metal 231 (232) and the hook receiving part 221 (222) constituting the locking device of the front door 12 are provided, but the number of the sets is not limited to this. Absent. For example, one set may be provided, or three or more sets may be provided. However, it is desirable to provide at least one set (one hook receiving portion) in a portion of the side plate 11e on the housing 11 side facing the side plate portion 410e on the surface changing unit 400 side.

  (K) In the above-described embodiment, the metal fittings 231 and 232 of the front door 12 have a rotation axis directed in a substantially horizontal direction (left and right direction), so that However, this may be changed as follows. That is, it is good also as a structure which turns the right-and-left metal fitting to the right and left with respect to the hook receiving part by the side of the housing | casing 11 because the rotation axis | shaft of a metal fitting turns to a substantially perpendicular direction (up-down direction).

  (L) In the above embodiment, the inner casing 410 is integrally formed of synthetic resin using a mold. However, after this is changed and each plate portion constituting the inner casing 410 is provided separately. It is also possible to form the inner casing 410 by connecting these plate portions by a fixing means such as adhesion or a fastener such as a screw. The material of the unit main body is not limited to synthetic resin, and light metal such as aluminum or wood can be used.

  (M) In the above embodiment, as shown in FIG. 16 and the like, the outer surfaces of the side plate portions 410d and 410e of the inner housing 410 are continuous surfaces that incline toward the inner side of the inner housing 410 from the front to the rear. However, the outer surface of the side plate portions 410d and 410e may be configured as discontinuous uneven surfaces that are stepped from the front portion to the rear portion. In such a case, the amount of standing of the guide ribs 470 formed on the side plate portions 410d and 410e may be increased stepwise from the front portion to the rear portion.

  (N) 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.

  (O) 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 portion with low friction and a portion with high friction. 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.

  (P) 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.

  (Q) In the above embodiment, as shown in FIG. 13 and the like, the lever member 610 is provided at the lower portion of each side plate portion 410d, 410e of the inner housing 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.

  (R) 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.

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.

  (T) In the above-described embodiment, the inner door 700 is provided in the surface changing unit 400. However, the inner door 700 may not be provided.

  (U) 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.
