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

  The following means are described as follows. "In a slot machine which is a kind of gaming machine, a reel device, a medal payout device, various control devices (including a main board), a power supply device, etc. are mounted inside a housing, and a front side of the housing is provided on the front side of the housing. The front door that can be opened and closed is provided with an auxiliary display device, a medal insertion device, a start lever, a stop button, etc. When playing a game, the player inserts medals (or bets) or starts each time the game is played. When the operation is performed, the reel of the reel device starts to rotate, and a symbol attached to the outer peripheral surface of the reel is variably displayed through the display window, and various effects are displayed by the auxiliary display device. Thereafter, the reel stops rotating when the stop button is pressed by the player or when a predetermined time elapses. A profit state is provided to the player, such as payout of medals, in accordance with a stop symbol that is visually recognized through the slot machine. Fraudulent activities have been reported, such as the intrusion of a fraudulent tool, causing the control device to malfunction, and the malfunction of the sensor that detects the insertion of medals, causing the player to repeat the game without actually inserting medals. On the other hand, there is disclosed a slot machine in which a fraud prevention plate is attached to the inside of a wall plate constituting a housing so as to extend from the front edge thereof to the front of the gaming machine, thereby suppressing the fraud. In this case, even if an attempt is made to intrude an illegal tool through the gap between the housing and the front door, the intrusion into the housing is prevented by the anti-fraud plate. Play With the diversification of contents, in order to provide players with more novel and interesting games, there is a tendency for game machine models to be changed in short cycles, and in response to this, reel devices and main boards 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 a housing (for example, Patent Document 1). However, in the configuration provided with the display unit as described above, if the anti-fraud plate is attached to the housing side as described above, the unit is protected from fraud when the display unit is replaced. When the tamper-proof plate is deformed or misaligned, the tamper-proof function of the tamper-proof plate may be deteriorated. In a lot machine, it is necessary to attach a fraud prevention plate to a housing. For example, when manufacturing a slot machine, the work of attaching the fraud prevention plate may not be performed due to an error. Furthermore, in order to attach the anti-fraud plate to the housing, it is necessary to use fixing tools such as screws, which causes an increase in the number of parts of the slot machine and an increase in the number of processes in manufacturing the slot machine. It is feared that it may cause it. The invention has been made with the problem to be solved.

Means 1. A housing (housing 11) opened to the front of the gaming machine and having left and right side plates (left plate 11d, right plate 11e), a top plate (top plate 11a) and a bottom plate (bottom plate 11b) passed over each side plate; ,
An overhanging portion (overhanging portion) that is provided so as to close the front opening of the housing, and that protrudes around the peripheral edge so as to contact or approach the front end surfaces of the left and right side plates, the top plate, and the bottom plate of the housing. 15) a front door having a front door (front door 12);
A pattern display device (reel device 650) that has a plurality of revolving bodies (reels 655 to 657) on which a plurality of types of patterns are arranged in the circumferential direction and that displays the patterns by rotating the revolving bodies is a unit body (inside). And 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 placed in a state where the side wall portions of the unit main body face each other along both side plates of the housing. Attach to the housing,
At least one front edge of both side walls of the unit main body protrudes from the front end surfaces of both side plates of the housing over substantially the entire area toward the front of the gaming machine, and the inside of the inner peripheral edge of the overhang of the front door. A gaming machine characterized in that it is located at

  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 inside the housing. The unit body has left and right side walls, and is mounted in a state where the both side walls face each other along both side plates of the housing. When the display unit is completely mounted, at least one of the side walls of the unit main body projects forward of the front end of each plate of the housing over substantially the entire front edge thereof (that is, at the same height). When compared in a horizontal section, each board protrudes forward from the front end of the game machine), and is located inside the inner peripheral edge of the overhang of the front door. For this reason, the gap between the front end face of the side plate of the housing and the front door (hereinafter, also referred to as a boundary portion) is blocked from the inside, and is performed through the gap between the housing and the front door. It is possible to suppress a fraudulent act such as erroneously operating a sensor or the like inside the gaming machine using a fraudulent tool.

  When the side walls of the unit body are opposed to each other along the side plates of the housing, the side walls and the side plates may be in contact with each other, or there may be a space (gap) between the side walls and the side plates. You may. In particular, when a space is provided between the side plate and the side wall portion, even if an unauthorized device is inserted from the gap between the side plate of the housing and the front door, the entry direction of the unauthorized device is set in a predetermined direction by the side wall portion. It is possible to guide. For example, when it is desired to guide a fraudulent tool to the rear of the gaming machine, a configuration in which a gap from the side plate of the housing is large at a rear portion of the side wall portion (a configuration in which the rear side of the housing is inclined inward of the housing). I just need.

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

  Further, since the shielding portion (side wall portion of the unit main body) is configured as a part of the unit main body constituting the display unit, unlike the configuration in which the shielding member is provided separately, the shielding member is not attached. In such a state, it is possible to preferably prevent the gaming machine from being installed in a game hall or the like, or from inconvenience such as forgetting to attach a shielding member when replacing the display unit. Further, the gap between the housing and the front door can be shielded without increasing the number of parts of the gaming machine and the number of steps in manufacturing the gaming machine. As described above, it is possible to simplify the configuration and reliably obtain the desired fraud suppression effect.

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

  The “state in which the side walls face each other along the side plates of the housing” refers to a state in which the side walls of the unit body are in contact with the side plates of the housing, or a close interval between the side plates and the side plates is maintained. Indicates the status. The side plate and the side wall (specifically, the outer surface) may or may not be parallel. For example, the case where at least one of the outer surface of the side wall portion and the inner surface of the side plate has irregularities is also included.

  “Almost the whole area” means that a component on the unit side (for example, a door support, etc.) is attached to a part of the front edge of the side wall of the unit body, or interference with other parts (for example, a front door) is avoided. By providing a notch or the like, the entire region of the front end edge of the side wall portion includes a state where it does not completely protrude from the side plate.

  In the present specification, "removably" means that the object to be detached is not fixed by a fixing tool such as a screw or a fixing means such as welding, and has an easily detachable configuration.

Means 2. The unit main body has, in addition to the left and right side walls, an upper wall (top plate portion 410a) above the both side walls, and the upper wall portion serves as a top plate (top plate 11a) of the housing. A gaming machine in which the unit main body is attached to the housing in a state facing along the
Almost the entire front edge of the upper wall portion of the unit main body projects forward from the front end surface of the top plate of the housing, and is located inside the inner peripheral edge portion of the overhanging portion of the front door. 2. The gaming machine according to claim 1, wherein:

  According to the means 2, the unit main body has the upper wall, and is mounted in the housing in a state where the upper wall faces along the top plate of the housing. The upper wall portion of the unit main body extends forward from the front end of the top plate of the housing when the unit main body is mounted, and is located inside the inner peripheral edge of the overhanging portion of the front door. It is configured. For this reason, the gap between the front end surface of the top plate of the housing and the front door is blocked from the inside, and it is possible to suppress an illegal act performed through the gap.

  Means 3. The gaming machine according to claim 1 or 2, wherein the unit main body is configured to form a housing open forward.

  According to the means 3, the unit body has a housing shape. For this reason, even if an illegal 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 main 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 housing), the unit main body forms a housing, and along the both side plates and the top plate of the housing. As a result, the upper and lower corners of the boundary between the housing and the front door can be shielded. Therefore, it is possible to expect an excellent suppression effect against fraud in the upper left and right corners.

  Means 4. Any one of means 1 to 3, wherein a shielding portion (e.g., a mounting base 460) is provided on each wall of the unit main body at equal intervals to a boundary portion between the housing and the front door. 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, as in the means 4, the boundary between the housing and the front door (that is, the side plate of the housing) is opposed at equal intervals. It is preferable to provide a shielding portion to be provided on each wall of the unit body. Thereby, a practically preferable configuration can be realized.

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

  The front door tends to be opened and closed frequently for maintenance (power on / off, refilling medals, etc.), etc. As described above, by providing an overhang on the periphery of the front door, the rigidity of the door itself is increased. It is possible to increase. Further, in the configuration in which the overhang portion is provided, the distance between the picture display device and the front side of the front door is shortened by adopting a configuration in which a part of the unit body is housed in the space in the overhang portion, Visibility is improved. That is, it is possible to secure 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 also projecting the picture display device forward.

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

  According to the means 6, the restricting portion or the restricting member for restricting the lateral movement of the unit main body when the unit main body is attached or detached is provided on at least one of the side plate of the housing and the side wall of the unit main body. For this reason, the unit main body can be prevented from shifting left and right inside the housing, and the workability when attaching and detaching the unit main body (display unit) can be improved. Also, due to the bias of the unit main body to the left and right when the unit main body is completely mounted, the clearance between the side plate of the housing and the side wall of the unit main body at one of the left and right boundary parts is increased. Can be suppressed. Even if an attempt is made to create a portion where an illegal tool can be easily inserted by causing the unit main body to shift by shaking the gaming machine main body or the like, the movement of the unit main body to the left and right is restricted as described above. Therefore, this can be prevented.

  Means 7. A support member (support rail 300) for movably supporting the unit main body in the housing is provided in the housing, and the display unit is moved to the rear of 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 housing by moving to the side.

  According to the means 7, the support member is provided in the housing, and the display unit is moved to the back side of the housing in a state where the unit body is in contact with the support member, so that the display unit is mounted on the housing. The configuration was adopted. When the unit main body is mounted, the unit main body is pushed in a state of being placed on the support member, whereby the inclination in the left-right direction is suppressed, and the inconvenience of interference between the side plate on the housing side and the side wall portion on the unit main body side can be suppressed. . In particular, in combination with the means 6 (a configuration in which a regulating member for regulating the movement of the unit body in the left-right direction is provided), in addition to the left-right inclination of the unit body, the left-right displacement can be regulated, the Mounting work can be further facilitated.

Means 8. The side wall of the unit body is inclined inward of the housing from the front side to the rear side of the housing,
A protrusion is provided on the side wall as the restricting portion extending in the mounting direction of the display unit, and an amount of the protrusion on the rear side of the housing is determined by an amount of the protrusion on the front side of the housing. The gaming machine according to claim 7, wherein the gaming machine is larger than the gaming machine.

  According to the means 8, the side wall portion of the unit main body is inclined from the front side of the housing toward the back side toward the inside of the housing (center side of the housing). It is configured to be smaller on the back side of the body, and ridges are provided on those side walls. When the display unit is mounted on the housing, the rear end of the ridge hits the housing or a component on the housing when the display unit is mounted on the housing. In addition, the impact can be easily absorbed by the ridge itself deforming (for example, elastically deforming). In addition, by increasing the size of the ridge, it is possible to ensure the function of restricting the displacement of the display unit even if the end is slightly crushed or shaved.

  In addition, on the front side of the unit body, the space between the side wall and the side plate of the housing is reduced to reduce the space in which the unauthorized device can freely move when the unauthorized device or the like enters.

  For example, the side wall portion may be formed in a slope shape in which the interval with the side plate of the housing gradually increases or decreases, or in a step shape in which the interval with the side plate of 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 at the back of a section in which the display unit moves to the mounting completion position when the display unit is mounted on the housing. A gaming machine according to claim 7 or 8, wherein:

  According to the means 9, when the display unit is mounted on the housing, a braking section for suppressing the movement of the display unit in the mounting direction is provided at the back of the section in which the display unit moves to the mounting completed position. In this case, the braking of the display unit is performed in the braking section, which is the section where the mounting is completed, and the moving speed of the display unit is suppressed. For this reason, when the display unit moves to the mounting completed position, it is possible to reduce the impact caused by colliding with the housing side.

  If the display unit is pushed into the housing with a vigorous force, it may rebound when the display unit moves to the mounting completion position, and the mounting position of the display unit may vary. In the present invention, the boundary portion between the front door and the housing is configured to be shielded from the inside by the side wall portion or the like of the unit main body, and when the mounting completion position of the display unit varies as described above, the shielding of the boundary portion is sufficiently performed. Not expected. However, by performing the braking of the display unit in the braking section before the mounting of the display unit, it is possible to suppress the inconvenience of the display unit bouncing from the mounting completed position, and to shield the boundary portion between the front door and the housing. Can be ensured.

  In addition, when the display unit moves to the mounting completed position, it may rebound and rebound, resulting in a state where the display unit is displaced toward the front of the gaming machine. When the front door is closed in such a state that the display unit is shifted to the front of the gaming machine, there is a concern that the front door may interfere with a front portion of the display unit (for example, an inner door or an auxiliary display device). However, as described above, by braking the display unit, interference between the front door and the display unit can be avoided.

  Means 10. In a section in which the display unit moves to the mounting completed position when the display unit is mounted on the housing, a low frictional resistance is generated between the unit main body and the supporting member or another housing-side contact member that comes into contact with the unit main body. 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 The gaming machine according to the means 7 or 8, wherein the gaming machine is provided so as to be on the back side.

  According to the means (10), two sections (low friction section, high friction section) having different levels of frictional resistance between the unit body and the support member or the casing side contact member when the unit body is mounted on the casing are provided. Have been. In this case, the display unit can be moved more easily on the front side of the gaming machine, that is, in the low friction section where the mounting is started, than in the high friction section. On the other hand, in the back side of the gaming machine, that is, in the high friction section, which is the section where the mounting ends, the movement of the display unit is hindered because the frictional resistance increases. For this reason, when the display unit moves to the mounting completed position, it is possible to reduce the impact caused by colliding with the housing side.

  If the display unit is strongly pushed into the housing, there is a possibility that when the display unit moves to the mounting completion position, the mounting completion position of the rebound display unit varies due to recoil. In the present invention, the boundary part between the front door and the housing is shielded from the inside by the side wall part of the unit body or the like, and as described above, when the mounting completion position of the display unit varies, the shielding of the boundary part is sufficiently performed. Not expected. However, by performing the braking of the display unit in the braking section before the mounting of the display unit, it is possible to suppress the inconvenience of the display unit bouncing from the mounting completed position, and to shield the boundary portion between the front door and the housing. Can be ensured.

  Further, when it is assumed that a cushioning member such as a spring or rubber is used when the display unit moves to the mounting completed position and the cushioning member is deformed to brake the display unit, the display unit repels the cushioning member. As a result, there is a possibility that the position of the bouncing machine is shifted to the front side. When the front door is closed in such a state that the display unit is shifted to the front of the gaming machine, there is a concern that the front door may interfere with a front portion of the display unit (for example, an inner door or an auxiliary display device). You. As described above, by performing the braking of the display unit by friction, when the display unit reaches the mounting completed position, the gaming machine can be configured to have no energy for moving the display unit, Positioning accuracy can be improved. Therefore, it is 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 provided continuously. By shifting from a state in which the frictional resistance is low to a state in which the frictional resistance is high, it becomes possible to rapidly increase the frictional resistance at those boundaries. As a result, the difference between the two sections can be made clearer than in the case where the frictional resistance gradually increases. In this case, when the display unit is pushed in, the display unit passes through the boundary between the low friction section and the high friction section, so that the display unit approaches the arrangement completion position and informs the operator that the display unit is in the section to be braked. It is possible to suggest. Accordingly, it is possible to suppress a variation in the mounting completion position of the display unit and to more reliably shield a boundary portion between the front door and the housing.

Means 12. The support member is configured to be in contact with the unit body in a section in which the display unit moves to a mounting completion position when the display unit is mounted on the housing,
The gaming machine according to claim 11, wherein the low friction section and the high friction section are provided such that friction resistance generated between the support member and the unit body is different in height.

  According to the means 12, since the unit main body is in contact with the support member with its own weight, the braking force (friction resistance) can be more effectively obtained by utilizing the own 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, there is no need to separately adjust the braking force when changing the model. That is, even when the weight of the display unit is changed, it is possible to obtain a braking force corresponding to the change. Assuming that the display unit is braked by separately providing a buffer member (rubber, spring, or the like), it may be necessary to change the buffer member with a change in the weight of the display unit. On the other hand, if the braking is performed by the frictional resistance using the own weight of the display unit, it is not necessary to change the support member and the like according to the replaced display unit. Therefore, the reusability of the braking member can be improved.

  Means 13. In the low friction section, the support member and the unit main body are in contact with each other by a rolling member (roller 540) provided on one of them, and in the high friction section, the rolling between the support member and the unit main body is performed. 13. The gaming machine according to claim 12, wherein the contact by the member is released.

  According to the means 13, in the low friction section, the support member and the unit body come into contact with each other by the rolling member provided on one of them, and in the high friction section, the contact by the rolling member is released, and the support member and the unit body are released. Contact. When a rolling member is included in the contact target, the rolling member rolls, so that the frictional resistance can be relatively reduced. Thereby, a difference can be caused in the frictional resistance in each section.

Means 14. Either the support member or the unit main body has a first contact surface (contact surface 321a) with which the other contacts,
The other of the support member or the unit main body has a second contact surface (slide rail sliding surface 512a) that contacts the first contact surface, and contacts the first contact surface and the display unit.

  A long hook receiving metal member 220 is fixed to the right side plate 11e of the housing 11 along a peripheral edge of the opening of the housing 11 by a fastener (not shown) such as a screw. Further, hook receiving portions 221 and 222 for holding the front door 12 in a closed state are provided at two upper and lower locations of the hook receiving fitting 220. The front door 12 is held closed by the housing 11 by the hook receiving fitting 220.

  Referring to FIG. 5 again, a locking device is provided on the back surface of the right side of front door 12, that is, on the side opposite to the opening / closing axis of front door 12. The locking device includes a base frame (not shown) extending in the vertical direction and fixed to the front door 12, a key cylinder 71 provided to extend from the upper part of the base frame to the front of the front door 12, And an elongate interlocking rod (not shown) assembled so as to be movable in the direction. Only the key cylinder 71 of the locking device is provided so as to protrude forward of the front door 12. In the present embodiment, an OMLOCK (trade name) having a high function of preventing unauthorized unlocking is used as the key cylinder 71. The interlocking rod is moved downward by operating the operation key K inserted into the key cylinder 71 clockwise. The interlocking rod is provided with a pair of upper and lower hooks 231 and 232 having a hook shape corresponding to the hook receiving portions 221 and 222. When the front door 12 is closed with respect to the housing 11, The respective hook fittings 231 and 232 are locked by the respective hook receiving portions 221 and 222 to be in a locked state. Each of the hooks 231 and 232 is provided with an urging member such as a coil spring for urging the hook to maintain the locked state. When the operation key K is operated clockwise with respect to the key cylinder 71, the interlocking rod moves downward, and the hooks 231 and 232 are moved against the urging force of the urging member. The locked state between the hooks 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, elongated plates 240 and 241 extending to the left and right are arranged along the upper edge and the lower edge of the inner peripheral edge of the housing 11. . These plates 240 and 241 are fixed to the top plate 11a and the bottom plate 11b by fasteners (not shown) such as screws. The 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 an opening of the housing 11.

  The front ends of the plates 240 and 241 protrude forward of the slot machine 10 from the opening edge of the housing 11, and the front ends of the brackets 200 and 220 also protrude forward of the slot machine 10 over the entire opening edge. ing. That is, when the plates 240 and 241 and the metal fittings 200 and 220 are attached to the housing 11 with the front door 12 closed, the opening edge of the housing 11 and the outer rear end of the front door 12 face each other. It is configured to close the gap between the parts from the inside. By arranging the metal fittings 200 and 220 and the plates 240 and 241 in this way, even if wire or film is allowed to enter from the above-described gap, it can be prevented, and illegal acts are prevented.

  Further, bent portions 242 and 243 are formed at both left and right end portions of the plate 240 so as to be bent vertically so as to face the inside of the housing 11. The 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 to overlap with the front side of the opening edge of the housing 11. (The relationship between the right bent portion 243 and the metal fitting 220 is shown in the partially enlarged view of FIG. 8). As described above, since the plate 240 and the metal fittings 200 and 220 overlap each other at the front of the corner of the opening of the housing 11, a gap generated at the same corner can be reduced. Thereby, it is possible to suppress intrusion of wires, films, and the like from those corners. It should be noted 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.

  At a substantially central position in the height direction in the housing 11 (above the hopper device 110), a partition plate 250 is horizontally mounted so as to extend between the left side plate 11d and the right side plate 11e. The inside of the housing 11 is vertically divided by the plate 250. The space above the partition plate 250 is an area where the surface changing unit 400 is installed. A bent portion (only the bent portion 251 formed at the rear end is shown in FIG. 8) is provided at each of the left and right ends and the rear end of the partition plate 250. . 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 employing a configuration without the partition plate 250.

(Description of support unit 260 and support rail 300)
On 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, a metal support rail 300 attached to the spacer member 270, and supporting and guiding the surface changing unit 400. It has. On the right side plate 11e of the housing 11, a right side support rail 300 having the same height and the same configuration as the left side 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. An elongated hole 272 extending in the longitudinal direction of the mounting portion 271 is formed substantially at the center of the mounting portion 271. Flanges 273 are formed at both ends in the short direction of the mounting portion 271 by being bent perpendicularly to the same side, and these flange portions 273 are provided with attachment portions 274 to the partition plate 250. The spacer 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 fixing means such as spot welding. In the present embodiment, the spacer member 270 is formed from a single iron plate, but may be formed from a light metal such as aluminum, or may be formed from a synthetic resin.

  Next, the support rail 300 will be described. The support rail 300 has an elongated shape 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 both 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 so as to be bent at a right angle. In a state where the support rail 300 is attached to the housing 11 side, the bending tip side of the guide piece 311 with respect to the base plate 310 is outside the slot machine 10, and the guide piece 311 is formed in the longitudinal direction of the base plate 310. This is the front side of the slot machine 10. Hereinafter, the support rail 300 will be described with reference to FIG. 11 based on these directions. At the end of the base plate portion 310 facing the side where the guide piece 311 is provided, a stopper piece 316 that is perpendicular to the base plate portion 310 and extends in the longitudinal direction of the base plate portion 310 is formed by being bent inward. I have.

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

  The lower guide portion 320 includes a horizontal portion 321 extending horizontally in the longitudinal direction of the base plate portion 310, a front inclined portion 322 formed by being inclined obliquely downward at a front side of the horizontal portion 321, and a horizontal portion 321. And a rear inclined portion 323 formed by being bent so as to be inclined 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 a front end. The resin piece 330 is provided so as to protrude above 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 and 332. And a top 333 connecting the tops of the two. In the present embodiment, the top portion 333 is configured as a plane, but is not limited to this, and may be configured so that its outer shape is curved (R shape). The resin piece 330 constitutes a fall prevention unit for preventing the surface changing unit 400 from falling, which will be described later in detail. Note that, instead of the resin piece 330, the fall prevention means may be configured by bending the front part of the support rail 300 to form a protruding part. Thereby, the number of parts can be reduced.

  A bent member 340 formed in a substantially L shape is attached to a front portion of the lower surface of the horizontal portion 321. The bending member 340 has a flat mounting portion 341 for mounting to the horizontal portion 321, and a seat surface 342 projecting below the horizontal portion 321 and orthogonal to the longitudinal direction of the horizontal portion 321. A tapered projection 343 is provided at substantially the center of the seat surface 342 so as to extend forward with reference to the longitudinal direction of the horizontal portion 321. In the present embodiment, the bending member 340 is provided separately, but may be formed by bending the lower guide portion 320.

  An upper guide portion 350 is formed at the upper end of the base plate portion 310 at the rear side thereof so as to be 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 into front and rear portions by a cut-and-raised portion 351 (a cutout 352) formed at a front portion thereof. ing. Reference numeral 350a indicates the divided front upper guide portion 350, and reference numeral 350b indicates the divided rear upper guide portion 350. A stopper 353 is formed at an upper portion of the cut-and-raised portion 351 by bending the upper end thereof inward, and a rising portion 354 that rises upward is formed at an inner end of the stopper 353. The upper guide portion 350 corresponds to a slide rail 510 described later on the surface changing unit 400 side, and has a function of suppressing the floating of the surface changing unit 400 together with the slide rail 510. Further, the cut-and-raised portion 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, and includes a stopper 353 and a rising portion. Reference numeral 354 constitutes an auxiliary means for assisting the unlocking operation together with the lever member 610. The detailed description of the upper guide portion 350 will be described later.

  The base plate part 310 is fixed by fixing means such as bolting or spot welding in a state of being in contact with the mounting part 271 of the spacer member 270. Thus, the support rail 300 is attached to the spacer member 270. At substantially the center of the base plate 310 of the support rail 300, a guide hole 312 extending in the longitudinal direction of the support rail 300 is formed, and the elongated hole 272 of the spacer member 270 is formed correspondingly. ing. That is, the guide hole 312 and the elongated hole 272 penetrate by positioning and attaching the support rail 300 to the spacer member 270. 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 has a function as a spacer for connecting the bent portion on the left side of the partition plate 250 and the support rail 300 at a distance. Here, the mutual relationship between 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 200 inside. The offset amount W2 by the spacer member 270 is set 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 bracket 200 from the left side plate 11d. Has been adjusted. This can prevent the face changing unit 400 from interfering with the door support 200 when the face changing unit 400 described later is attached to or detached from the housing 11.

  On the other hand, the hook plate 220 is provided inside the right side plate 11e of the housing 11. The protrusion amount W3 of the hook receiving member 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). In other words, 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 hook receiving metal 220 to support the surface changing unit 400. The width of the lower guide portion 320 can be secured. Therefore, it is possible to prevent the surface replacement unit 400 from interfering with the hook receiving fitting 220 when the surface replacement unit 400 is attached or detached without using a spacer member. The protrusion amount W3 of the hook receiving member 220 corresponds to the improvement of the rigidity of the opening of the housing 11, the improvement of the rigidity of the hook receiving member 220 itself, and a fraudulent activity performed from a boundary portion between the housing 11 and the front door 12. Tends to be bigger. In the case where the protrusion amount W3 becomes large and hinders the attachment / detachment of the face changing unit 400, interference can be avoided by providing a spacer member on the right side plate 11e similarly to the left side support unit 260.

  As described above, since the attachment / detachment of the surface changing unit 400 is not hindered by the metal fittings 200 and 220, it is not necessary to remove the metal fittings 200 and 220 each time the surface changing unit 400 is mounted. Can be efficiently attached and detached. Further, the offset of the support rail 300 is indispensable for efficient attachment / detachment of the face changing unit 400. However, if the offset amount W2 is meaninglessly increased, a disadvantage such as an increase in 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.

  Referring again to FIGS. 8 and 9, the support rail 300 is not only a long base plate 310 extending in the front-rear direction parallel to the side plates 11d and 11e, but also at the lower end of the base plate 310. A lower guide portion 320 is formed by being bent vertically inward, and an upper guide portion 350 is formed by being bent inward vertically at the upper end of the base plate portion 310. In this way, by arranging the guides 320 and 350 vertically instead of horizontally, the space in the left and right direction in the housing 11 can be effectively used. Further, in the present embodiment, each of the guide portions 320 and 350 is formed by bending both ends of one plate material to the same side, thereby reducing the number of components.

(Description of the face changing unit 400)
Next, the structure of the surface changing unit 400 that is mounted inside the housing 11 will be described. 13 is a perspective view of the face changing unit 400 as viewed from obliquely above, FIG. 14 is a perspective view showing the rear configuration of the face changing unit 400, FIG. 15 is a front view of the face changing unit 400, and FIG. 17 is a right side view of the face changing unit 400, FIG. 18 is a perspective view showing an open state of the inner door 700 of the face changing unit 400, and FIG. 19 is an exploded view of the face changing unit 400 for each main component.

  The face changing unit 400 is mainly composed of a box-shaped inner housing 410 having an open front side, a reel device 650 disposed inside the inner housing 410, and a right edge of an opening of the inner housing 410. And an inner door 700 that is attached so as to be opened to the near side with the portion (the side opposite to the opening / closing axis of the front door 12) as the 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. If the model change is performed in a game hall or the like, the face change unit 400 By replacing the unit 400 from the current model to a new model, the model can be replaced. That is, the replacement unit 400 constitutes a replacement unit at the time of model change or the like. Hereinafter, each component will be individually described in detail.

(Description of inner housing 410)
The configuration of the inner housing 410 will be described with reference to FIGS. FIG. 20 is a perspective view showing the configuration of the inner housing 410. The inner casing 410 is integrally formed of, for example, a synthetic resin such as ABS. In this case, manufacturing is facilitated by forming the inner casing 410 as a resin integrally molded product. A metal door support 740 is disposed on the right side of the front edge of the inner casing 410 (the side opposite to the door support 200 of the front door 12), and a hook receiving bracket 750 is provided on the left side of the front edge. Are arranged. Further, reinforcing plates 411 and 415 formed in a long shape are disposed on both upper and lower sides of the front side edge, and left and right ends of the reinforcing plates 411 and 415 are connected to metal fittings 740 and 750. . As described above, the reinforcing plates 411 and 415 and the metal fittings 740 and 750 are connected to each other to form a frame, and are 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 410a, a bottom plate 410b, a back plate 410c, a left plate 410d, and a right plate 410e, and is formed in a box shape with an open front side as a whole. The inner housing 410 may be formed of a wooden panel or a metal panel other than the synthetic resin, or may be formed of a single box using wood or a metal material. .

  As shown in FIG. 20, the front portion of the top plate portion 410 a has a double wall plate formed inside and outside, and a large number of reinforcing ribs 420 are provided between these wall plates so as to connect them. . A portion where the reinforcing rib 420 is provided serves as a grid-like reinforcing bar portion 421, and a through-hole 422 as a handle portion is formed at the center of the reinforcing bar portion 421. 13 to 19, a reinforcing plate 411 is fixed to the reinforcing bar portion 421 by a fastener such as a screw, and a substantially central portion of the reinforcing plate 411 corresponds to the elongated through hole 422. Thus, a notch 412 is formed. By passing a finger through the through-hole 422, the inner casing 410 (the surface changing unit 400) can be easily lifted. In addition, openings 423 that penetrate inward and outward are formed at a plurality of places (four places in the figure) behind the reinforcing bar 421, and heat is applied from inside the surface changing unit 400 through these openings 423. Air can be exhausted.

  A plurality of main ribs 425 extending in the mounting / removing direction of the surface changing unit 400 and a plurality of sub-ribs 426 extending crossing the main rib 425 are formed on the top plate portion 410a. An inclined surface 427 that is inclined obliquely downward is formed at the rear of the main rib 425. These ribs 425, 426 have a function as a reinforcing portion for increasing 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 planar shape as a whole, and constitutes a mounting portion for placing the surface changing unit 400 on the ground or the like when transported alone. When the face changing unit 400 is completely mounted inside the housing 11, a part of the front side of the bottom plate portion 410b projects forward with respect to the front edge of the partition plate 250. The portion 430 is provided with a horizontally long through-hole 431. In addition, a reinforcement slot (not shown) is provided in the reinforcement plate 415 corresponding to the through-hole 431. By providing the through-holes 431 in this manner, it is possible to easily perform the work by pushing and pulling the fingers through the through-holes 431 when attaching and detaching the face changing unit 400.

  As shown in FIG. 20, on the inner surface of the bottom plate portion 410b, a ridge portion 435 extending forward and backward along each side plate portion 410d, 410e is provided on the left and right. At substantially the center of the front surface of each of the protrusions 435, columnar protrusions 436 are provided so as to extend toward the near side. A screw hole 437 for screwing is provided at the center of the projection 436. FIG. 20 shows a left protrusion 435, a left protrusion 436, and a left screw hole 437.

  As shown in FIG. 17 (side view of the surface changing unit 400), the back plate portion 410c has a substantially planar shape. The back plate portion 410c is formed so as to be substantially parallel to the back plate 11c of the housing 11 when the face changing unit 400 is completely mounted in the housing 11. For this reason, the generation of dead space in the depth region of the housing 11 can be suppressed, and the depth region can be effectively used. Further, it is also possible to suppress the installation of an unauthorized board or the like in the dead space.

  A step 440 recessed in a step shape is formed at the lower portion of the back plate 410c. Protrusions 441 projecting rearward are provided on both left and right sides of the step portion 440. When the replacement unit 400 is completely mounted on the housing 11, the projections 441 abut on the bent portions 251 of the partition plate 250 (there is no interference between the back plate portion 410c and the back plate 11c). ), The positioning of the face changing unit 400 in the depth direction is performed. That is, each protrusion 441 and the bent portion 251 constitute a depth direction positioning means of the surface changing unit 400. In the present embodiment, the configuration is such that the protrusion 441 is in contact with the bent portion 251, but the configuration may be such that the protrusion 441 is in contact with the back plate 11c.

  The surface changing unit 400 is mounted by disposing a cushioning material having a low repulsive force, such as a urethane sponge or a 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 protrusion 441 and the bent portion 251 at the time of performing.

  As shown in FIGS. 14 and 16 (a rear perspective view of the surface changing unit 400 and a rear view of the surface changing unit 400), a horizontally long housing recess 442 is formed substantially at the center of the back plate portion 410c. At the bottom of the housing recess 442, a horizontally long hole 443 penetrating in and out is formed. Details of the accommodation recess 442 and the hole 443 will be described later.

A rectangular opening 450 is formed at an upper portion of the left side plate portion 410d so as to penetrate inside and outside. Below the opening 450, a rectangular opening 451 is also formed 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 portion 410c and the bottom plate portion 410b and that is recessed inward is formed below the left side plate portion 410d (below the lower opening portion 451).

  Next, the right side plate portion 410e will be described with reference to FIGS. Outside the right side plate 410e, a mounting base 460 extending along the front edge of the right side plate 410e is formed. The mounting base 460 forms a mounting portion for the door support bracket 740. It should be noted that the mounting base 460 is difficult to confirm in FIGS. A concave portion 462 connected to the back plate portion 410c is formed in an upper portion of the right side plate portion 410e. More specifically, the recess 462 has a shape capable of avoiding interference with an external terminal (not shown) provided on the upper inside of the right side plate 11 e of the housing 11 when the face changing unit 400 is mounted on the housing 11. It is formed with.

(Description of the slide rail 510)
As shown in FIGS. 13 and 18, a long slide rail 510 extending in the front-rear direction is provided below the recess 452 of the left plate 410 d and the lower part of the right plate 410 e. Since the right and left slide rails 510 have the same structure, the right slide rail 510 will be described below with reference to FIGS. This will be described with reference to an exploded perspective view showing an exploded part of the configuration of the stop means.

  The slide rail 510 has a long plate-shaped mounting plate portion 511 as a mounting portion to the right mounting portion 464. In the surface changing unit 400, a mounting portion 464 is provided at a portion facing the mounting plate portion 511, and the mounting plate portion 511 is fixed to the mounting portion 464 by a fastener such as a screw.

The second pressing portion 516 is formed by bending downward so as to form a predetermined gap with the portion 514. According to the upper end portion of the first holding portion 514 and the lower end portion of the second holding portion 516, an insertion portion 517 is formed therebetween. When the face changing unit 400 is completely mounted on the housing 11, the stopper 316 of the support rail 300 is inserted into the insertion portion 517. The insertion portion 517 is formed so as to be slightly larger than the stopper piece 316.

  A resin piece 520 is provided on the upper surface of the holding section 515. The resin piece 520 is provided so as to protrude above the holding portion 515, and has a contact portion 521 having a flat surface provided on an upper portion and a rearward inclined portion provided on the rear side of the contact portion 521 and inclined obliquely downward. And a surface 522. In the present embodiment, the contact portion 521 is configured as a plane, but may be configured so that the outer shape is curved. Further, the holding portion 515 may be formed by being bent in a protruding shape, so that the holding portion 515 may be used instead of the resin piece.

  A guide piece 530 is provided substantially at the center of the outer surface of the mounting plate 511. The guide piece 530 has a base portion 531 that protrudes outward, and the base portion 531 is fixed to the mounting plate portion 511 by fasteners such as screws. An arm 532 extending rearward is formed outside the rear portion of the base portion 531. The base portion 531 and the arm 532 project to a size that does not interfere with the base plate portion 310 of the support rail 300 when the inner housing 410 is mounted on the housing 11. At the rear end of the arm 532, a projection 533 projecting outward is formed. More specifically, the protrusion 533 is formed so as to fit into the guide hole 312 of the support rail 300 when the inner housing 410 is mounted on the housing 11.

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

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

  A roller 540 made of resin is rotatably provided behind the rear end of the supported portion 512, that is, below the rear of the right side plate 410e. More specifically, the roller 540 has a rotation axis in a direction orthogonal to the right side plate 11 e of the housing 11, and is rotatably supported by the mounting plate 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 face 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 320 of the support rail 300. . The slide rail 510 and the rollers 540 constitute a detachment assisting mechanism.

  A bent member 550 projecting below the supported portion 512 is separately provided on the slide rail 510. An engagement hole 551 that can be engaged with the projection 343 of the support rail 300 is formed in the bent member 550, and the engagement hole 551 is engaged with the projection 343, so that the inner housing 410 (the surface changing unit 400) is formed. ) Is performed.

  Since the engagement holes are provided in different shapes at two locations (on the left and right sides in the present embodiment), these differences will be described (see FIG. 15). One of the engagement holes (the right engagement hole 551 in the present embodiment) has a long hole shape extending in the vertical direction, and together with the right protrusion 343, the inner housing 410 (surface). The left / right positioning means for positioning the replacement unit 400) in the left / right direction is configured. On the other hand, the other engaging hole (the engaging hole 553 provided in the left bending member 552 in the present embodiment) has a long hole shape extending in the left-right direction, and the left protrusion 343. Together, they constitute a vertical positioning means for positioning the inner casing 410 in the vertical direction. That is, the above-described positioning means in the front-rear direction of the inner casing 410 and these left-right and up-down positioning means are configured independently of each other.

  The face changing unit 400 is likely to be heavy because it includes components such as the reel device 650, the inner door 700, and the main control device 770, and the impact due to a collision at the time of mounting is applied to each positioning means, and the deformation of these positioning means is caused. Etc. may occur. Therefore, in the present embodiment, the positioning means in the mounting direction (the front-rear direction in the present embodiment) which is considered to be most susceptible to impact is constituted by the projection 441 and the back plate 11c (bent portion 251). The inner housing 410 and the housing 11 receive the impact at the time of mounting. As described above, since the positioning means in the front-rear direction is independent of the left-right and up-down positioning means, the load on the left-right and up-down positioning means can be reduced. This makes it possible to maintain the positioning accuracy appropriately.

  Next, the configuration of the locking means for locking the inner housing 410 when the mounting of the inner housing 410 is completed will be described with reference to FIGS. As the locking means, a lever member 610 rotatably provided on each of the side plate portions 410d and 410e and substantially L-shaped in side view, and an urging member for urging the lever member 610 in the rotational direction thereof It is comprised including. Since each of these lever members 610 and each of the urging members have the same structure on both the left and right sides, the right lever member 610 and the right urging member will be described below with reference to FIGS.

  A lever member 610 is attached to the front of the right side plate portion 410e and above the right side mounting portion 464. That is, a lever communication hole 611 which is a rectangular through hole corresponding to the lever member 610 is formed in the right side plate portion 410 e, and the lever member 610 is connected to the inside and outside of the inner casing 410 through the lever communication hole 611. It is in a state of communicating with. A bearing hole 612 is provided below the lever communication hole 611 so as to penetrate inside and outside of the housing 11. A support shaft 613 corresponding to the bearing hole 612 is formed below the lever member 610. I have. The support shaft 613 is configured so that a part thereof is exposed to the inside of the inner housing 410 in a state 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. Are 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 while the support shaft 613 is fitted in the bearing hole 612. Since the support shaft 613 and the cylindrical portion 614 are provided so as to be relatively rotatable relative to each other, the lever member 610 is in a state where it can rotate with respect to the center axis of the support shaft 613. A substantially plate-shaped operating portion 615 extending upward is formed above the bearing hole portion 612, and extends below and vertically below the operating portion 615 at a lower portion of the operating portion 615 exposed to the outside of the inner housing 410. An arm 616 is provided. A hook 617 is formed at the tip of the arm 616 and protrudes downward so as to be able to be locked to the notch 352 of the support rail 300. 610 rotates with reference to the center axis of the support shaft 613, and the hook 617 moves upward.

  On the rear surface side of the operation unit 615, an overhang portion 618 that extends rearward is formed, and the overhang 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 a state where the overhang portion 618 contacts the inner wall of the lever communication hole 611 to a point where the front end portion of the lever member 610 contacts the lever communication hole 611. .

  A guide surface 619 which is inclined obliquely upward is formed on the rear side of the hook portion 617. The guide surface 619 allows the hook portion 617 to be attached to the upper guide portion 350 of the support rail 300 when the inner casing 410 is mounted. (Specifically, the notch 352). A hook 620 projecting outward is formed at the rear end of the outer surface of the arm 616, and a guide surface 621 that is inclined downward and outward is provided above the hook 620. I have. A constricted portion 622 extending vertically is formed at a front portion of the outer surface of the arm 616. When an external force is applied from the side to the rear side of the arm 616, for example, the hook 620, the arm 616 bends inward with respect to the constricted portion 622.

  Next, an urging member for urging 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 is configured such that the hook portion 617 is constantly biased 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 hook 617 may always be urged downward. Good. In addition, the locking means (the lever member 610 and the urging member) is provided on both the left and right sides. However, the present invention is not limited to this.

  Attaching and detaching assist mechanisms including the slide rails 510 and the rollers 540, regulating means including the guide piece 530, and locking means including the lever member 610 provided on the side plate portions 410d and 410e of the inner casing 410. Are configured not to protrude below 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 casing 410 (replacement unit 400) is placed on the floor or the like at the time of unit replacement or the like, the outer surface of the bottom plate portion 410b (the above-described placement section) comes into contact with the floor or the like. Accordingly, even when the inner casing 410 is inadvertently placed on the floor or the like, the attachment / detachment assisting mechanism, the regulating means, and the locking means provided on the side plates 410d and 410e may be deformed or damaged. A failure can be prevented, and it is also possible to prevent the roller 540 from rolling and the inner housing 410 from moving unexpectedly.

(Explanation of attachment / detachment work of inner casing 410)
The attachment / detachment work of the inner casing 410 (replacement unit 400) will be described with reference to FIGS. FIG. 23 is a partial schematic view showing a state of assembling the inner housing 410 when the inner housing 410 is viewed from the side, and FIG. FIG. FIG. 23A shows a state in which the roller 540 of the inner housing 410 is placed on the support rail 300, and FIG. 23B shows a moving state of the inner housing 410 with the rotation of the roller 540. 23 (c) shows a state where the inner casing 410 has been mounted on 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, when the inner housing 410 is moved to the mounting completion position when the inner housing 410 is mounted on the housing 11, the frictional resistance between the inner housing 410 and the support rail 300 in contact with the inner housing 410 is set. , And a high friction section that generates a friction resistance greater than the friction resistance generated in the low friction section, 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 make point contact in the low friction section, and the support rail 300 and the slide rail 510 make surface contact in the high friction section. As described above, by providing the low friction section (point contact section L1) and the high friction section (surface contact section L2), the workability of attaching and detaching the inner casing 410 can be improved, and the slot machine 10, especially the inner casing 410, etc. Protection and possible. Hereinafter, the details will be described.

  Here, “point contact” means that when the surface changing unit 400 (the inner casing 410) moves, a 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 perpendicular to the unit movement direction (that is, the same direction as the rotation axis). The contact may be linear, but if the contact portion in the unit movement direction is a point, this is also included in “point contact”. In addition, for example, when the rotating body comes into contact with the plate surface, it is also assumed that the contact portion of the rotating body expands due to a force such as weight. It is included in “point contact”.

  As shown in FIG. 23 (a), when mounting the inner housing 410 (surface changing unit 400), the roller 540 is placed on the horizontal portion 321 of the support rail 300, and the inner housing 410 is lifted to 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, even if the lifting height is slightly lower at the time of mounting, the front inclined portion 322 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 can be 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, Since the roller 540 is caught by the rear inclined surface 332, the inconvenience that the inner housing 410 is unintentionally dropped from the housing 11 does not easily occur. When the inner casing 410 is removed, the roller 540 hits the resin piece 330 by pulling the inner casing 410 toward the front, and the roller 540 is at the front end of the lower guide portion 320, that is, the inner casing 410. Can be suggested to the operator that is in a state immediately before detachment from the housing 11.

  Next, as shown in FIG. 23B, 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 casing 410 slides on the slide rail. The surface 512 a is supported by the resin piece 330 in contact with the resin piece 330, and the rollers 540 of the inner housing 410 are supported by the horizontal portion 321. That is, the inner housing 410 is supported by the support unit 260 of the housing 11 at a total of four points, two points on each side, so that the weight of the inner housing 410 can be quickly and stably placed on the housing 11 side. You can leave it. Further, since the support is performed at the four points (hereinafter, the state supported at the four points is referred to as a point contact state), the inner housing is supported with respect to the contact surface 321 a of the horizontal portion 321 of the support rail 300 of the housing 11. The slide rail sliding surface 512a of the slide rail 510 included in the body 410 is in a non-contact so-called floating state. 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 provided. The inner housing 410 can be moved back and forth while moving.

  The resin piece 330 not only functions as a means for preventing the inner casing 410 (replacement unit 400) from dropping, but also functions as a resistance reducing means for reducing frictional resistance when the inner casing 410 moves. Have. Focusing on this point, when the protrusion is formed by bending the front end of the support rail 300 instead of the resin piece 330, it is desirable to coat the protrusion with a fluororesin or the like having a low frictional resistance. .

  In the present embodiment, the amount of protrusion of the top 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 the contact surface 321a are substantially parallel. Here, for example, when the height of the resin piece 330 is set to be larger than the height, the front portion of the slide rail sliding surface 512a is lifted and the rear portion of the inner housing 410 is inclined so as to be lowered. It is possible to more easily move the housing 11 to the back side with the action of its own weight 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 separates from the lower guide portion 320. The unit-side pitch between the center axis of the roller 540 and the lower end of the guide portion 513 in the mounting / removing direction of the surface changing unit 400 is smaller than the housing-side pitch of the upper end of the rear inclined surface 332 and the upper end of the rear inclined portion 323. Are almost equivalent. Therefore, the guide portion 513 is guided to the rear inclined surface 332 of the resin piece 330 substantially in synchronization with the separation of the roller 540. That is, the state is shifted from the point contact state shown in FIG. 23B to a surface contact state in which the slide rail sliding surface 512a and the contact surface 321a are in surface contact. In addition, L1 shown in FIG. 23 is a point contact section in which the inner casing 410 is moved in a point contact state, and L2 is a surface contact section in which the inner casing 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 is Since it moves obliquely downward along the rear inclined portion 323, there is no inconvenience such as receiving an impact.

  In the surface contact state described above, the function of the roller 540 is deactivated, and the sliding 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 rear side of the casing 11 vigorously in a point contact state with a small frictional resistance, the frictional resistance increases when the inner casing 410 is shifted to the surface contact state. 23C, the inner side of the inner casing 410 reaches the mounting completion position (the position where the protrusion 441 of the inner casing 410 abuts on the bent portion 251 of the partition plate 250) shown in FIG. The momentum of the housing 410 can be reduced. By doing so, it is possible to suppress such a problem that the inside machine 410 collides vigorously with the back plate 11c of the casing 11 and the slot machine 10 is damaged.

  Next, an operation of removing the inner housing 410 will be described. When the inner casing 410 is removed, the operation is performed in the order of FIG. 23C → FIG. 23B → FIG. By pulling the inner casing 410 toward the near side from the mounting completion state shown in FIG. 23C, the roller 540 is lifted up to the contact surface 321a along the rear inclined portion 323, and the guide portion 513 is inclined rearward of the resin piece 330. It is lifted along the surface 332 to the top 333. In this case, since the roller 540 is guided by the rearward inclined portion 323 and the guide portion 513 is also guided by the rearward inclined surface 332, it can be relatively easily pulled. Then, by further pulling toward the near side, the roller 540 passes over the resin piece 330 as described above, and the detachment of the inner casing 410 is completed (see FIG. 23A). The contact surface between the support rail 300 and the slide rail 510 may be made of a material having low frictional resistance, or the contact surface may be coated with a fluororesin having low frictional resistance to improve the slip of the inner housing 410. In addition, the pushing or pulling of the inner casing 410 can be performed more easily.

(Explanation of operation of regulation means)
The operation of the restricting means for restricting the mounting / removing direction of the inner casing 410 when attaching / detaching the inner casing 410 will be described. As shown in FIG. 23 (a), when mounting the inner housing 410 (replacement unit 400), the roller 540 is placed on the contact surface 321a of the support rail 300, and the inner housing 410 is lifted up to fit inside the housing 11. Push into. When the inner housing 410 is pushed into the housing 11 as described above while being tilted back and forth, the main ribs 425 of the inner housing 410 contact the lower surface of the top plate 11a of the housing 11, and The main rib 425 moves on the lower surface of the plate 11a so as to slide. Thereby, the inconvenience that the inner housing 410 is obliquely inserted into the housing 11 is restricted.

  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 inclined left and right, the first box 480 and the guide rib 470 come into contact with each other, so that the inclination is reduced below the inner casing 410. Can be suppressed. When the inner housing 410 is further pushed into the inner side of the housing 11, the second box 490 and the guide rib 470 come into contact with each other, so that the inner housing 410 is tilted to the left and right. It is held down above. As described above, the regulating means (boxes 480 and 490 and the guide rib 470) are provided at a low position in the front and at a high position in the rear. Can be regulated on the upper side where displacement can be effectively suppressed. Furthermore, by regulating at four places in this way, rotation and torsion of the inner casing 410 to the left and right can be effectively suppressed, so that an unexpected shift after the completion of mounting can be suppressed.

  That is, the ribs 425 and 470 not only function as reinforcing portions for increasing the rigidity of the respective plate portions 410a, 410d and 410e, but also have a function of restricting displacement when the face changing unit 400 is mounted on the housing 11. I have.

  Since the main rib 425 has the inclined surface 427, there is no problem that the main rib 425 is caught on the front edge of the top plate 11a when the inner casing 410 is pushed in, and the pushing operation is not hindered. Further, the projecting amount of the sub rib 426 is smaller than that of the main rib 425, so that the pushing operation is not hindered. Similarly, since each guide rib 470 is also provided with the inclined surface 471, there is no problem that the guide rib 470 is caught by the boxes 480 and 490 when the inner casing 410 is pushed in, and the pushing operation is not hindered. Further, 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.

  Further, as shown in FIG. 23B, when the inner housing 410 reaches a predetermined position in a state where the inner housing 410 is supported at four points by the support rail 300, the resin piece 520 of the slide rail 510 is formed. Is configured to approach 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 determined by the distance between the lower end of the roller 540 and the contact portion 521 in the vertical direction. It is provided to be slightly smaller than the distance between 320 and 350. Accordingly, it is possible to restrict the inner casing 410 from rotating with the resin piece 330 as a reference, and the rear part of the inner casing 410 from rising upward. In the present embodiment, when the inner casing 410 is shifted to the surface contact state, the resin piece 520 is also separated from the upper guide section 350 as the roller 540 is separated from the lower guide section 320. Configuration. By forming an inclined portion and a stepped portion along the movement of the resin piece 520 at the rear portion of the upper guide portion 350, it is naturally possible to make the vertical regulation effective until the mounting is completed.

  The present embodiment is characterized in that, in addition to the above-mentioned regulating means, a guiding means comprising the guide piece 530 and the guide hole 312 for regulating a small displacement is provided. That is, the inner housing 410 whose attachment / detachment direction is regulated by the regulating means is guided to a predetermined position by the guiding means. Hereinafter, the specific operation of the guidance means will be described.

  When the inner casing 410 (replacement unit 400) is placed on the support rail 300 and pushed down to a predetermined position, the protrusion 533 of the guide piece 530 contacts the guide piece 311 of the support rail 300. By further being pushed, the projection 533 is guided on 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 urged toward the base plate 310.

  When the inner casing 410 is further moved to the rear side and the protrusion 533 of the arm 532 reaches the guide hole 312, the protrusion 533 is guided by the arm 532 trying to restore its original shape by elastic force. It fits in the hole 312. Then, with the further movement of the inner housing 410 to the back side, the protrusion 533 also slides and moves in the guide hole 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 holes 313 to 315 are respectively provided corresponding to the moving direction of the roller 540. That is, when the protrusion 533 exists in the front horizontal hole 313, the roller 540 is on the horizontal portion 321, and when the protrusion 533 exists in the inclined hole 315 (point contact state), the roller 540 moves backward. In a state where the protrusion 533 is located on the inclined portion 323 and the projection 533 is present in the rear horizontal hole portion 314 (surface contact state), the roller 540 is separated from the lower guide portion 320. It is desirable that the inclination of the inclined hole 315 is equal to the inclination of the rear inclined part 323. By doing so, even when the roller 540 is rolling on the rear inclined portion 323, the movement of the roller 540 and the movement of the guide piece 530 can be synchronized.

  As described above, when the inner housing 410 is pushed or pulled out, the protrusion 533 is moved in a state where the guide hole 312 is fitted in accordance with the movement of the inner housing 410, so that the direction of the pushing or pulling is performed. Is guided, so that the displacement in the vertical direction hardly occurs. That is, it is not necessary for the operator to adjust the pushing or pulling-out direction when attaching / detaching the inner casing 410, and it is possible to suitably suppress the complexity of the work. Furthermore, since the regulating means and the guiding means are provided independently, a large displacement can be regulated by the regulating means, and a small displacement can be regulated by the guiding means. It is possible to guide to a predetermined position (mounting position) without performing.

  Further, the guide piece 530 also has the function of preventing falling off as described above. The dropout prevention function will be described in detail with reference to FIGS. Referring to FIG. 11, 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) is formed at the front end of the guide hole 312 of the support rail 300. (Only the lower inclined surface 318 is shown in the figure). As shown in FIG. 22, a hook 535 corresponding to the front edge of the guide hole 312 is formed at the front of the projection 533 of the guide piece 530. The hook portion 535 has a wall shape standing substantially perpendicularly to the outside of the inner housing 410 from the arm 532, and can be locked to the front edge of the guide hole portion 312.

  When the inner casing 410 (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 housed in the guide hole 312 of the support rail 300, and the inner casing 410 is moved to a predetermined position. , The hook 535 of the guide piece 530 comes into contact with the front edge of the guide hole 312, and further movement of the inner housing 410 is restricted.

  As described above, before the inner housing 410 is completely pulled out of the housing 11, the movement of the inner housing 410 is restricted, and the drawer is once restricted, so that the inner housing 410 may fall out unexpectedly. Can be avoided. By restricting the movement of the inner housing 410, it is possible to notify the worker that the inner housing 410 is in a state where the inner housing 410 can be detached, and the inner housing 410 (specifically, the rollers 540) is supported by the support rail 300. (Specifically, with respect to the contact surface 321a), the withdrawal operation can be performed without the operator visually checking the position.

  If the movement of the inner housing 410 is restricted when the inner housing 410 is pulled out, the inner housing 410 is tilted backward at a predetermined angle (about 10 ° in the present embodiment) or more, so that the projection of the guide piece 530 is first provided. 533 abuts on the inclined surface 318, and the projection 533 is moved upward along the inclined surface 318 while the arm 532 is bent inward of the housing 11, and the projection 533 is separated from the guide hole 312. Thereby, the movement restriction of the inner housing 410 is released, and the inner housing 410 can be further pulled out. When the inner housing 410 is detached, the movement of the inner housing 410 is temporarily stopped as described above without visually checking whether or not the inner housing 410 is placed on the support rail 300. Thus, the operator can easily recognize that the inner casing 410 is about to be separated. Therefore, when the inner housing 410 is detached, the weight load of the inner housing 410 is prevented from being transferred to the worker in a state not intended by the operator, and the inner housing 410 can be prevented from falling off.

(Description of operation of locking means)
The operation of the locking means will be described again with reference to FIGS. When the inner housing 410 (surface changing unit 400) is pushed into the inner side of the housing 11 along the support rail 300, the state is changed from the point contact state to the surface contact state as described above. After the shift to the surface contact state, by continuing the pushing operation, the hook portion 617 of the lever member 610 comes into contact with the front end of the upper guide portion 350. With the pushing operation, the hook portion 617 is lifted upward along the guide surface 619 against the urging by the leaf spring 631, and rests on the upper guide portion 350. Then, in synchronization with the positioning of the inner casing 410 in the front-rear direction, the hook 617 fits into the notch 352, and the hook 617 is locked to the front edge of the notch 352. That is, the inner casing 410 is in a state where the forward movement is restricted.

  When the hook 617 is locked in the notch 352, the operating portion 615 of the lever member 610 is tilted forward against the bias of the leaf spring 631, and the center of the support shaft 613 is set as a reference. Since the lever member 610 rotates, the hook 617 separates 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 cut-and-raised portion 351. That is, 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. When the operation unit 615 is further tilted forward, the hook 620 is guided on the side surface of the upright 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. The hook 620 is locked to the upper edge of the upright portion 354 as the bending of the arm 616 is restored to the original state when the hook portion 620 is moved to above the upper end of the upright portion 354. You. As a result, the hook portion 620 is held by the upright portion 354, and the lever member 610 is maintained in a state where the tilting operation is performed (see FIG. 25). That is, after the tilting operation of the operation unit 615, it is not necessary to continuously hold the operation unit 615, 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. Further, after the inward operation of the lever member 610, by pulling the inner housing 410 toward the near side, the hook portion 620 slides on the upright portion 354 and moves away from the upper guide portion 350.

  Referring to FIG. 24 again, a state in which the inner casing 410 is completely mounted on the casing 11 will be described.

  On the rear side of the housing 11, the stopper 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 housing 410 is further pushed into the inner side of the housing 11, and the above state is achieved. Accordingly, when the rear portion of the inner housing 410 moves up and down unexpectedly, the stopper piece 316 abuts on the insertion portion 517 to suppress the movement. On the other hand, on the front side of the housing 11, the protrusion 343 of the support rail 300 is engaged with the engagement holes 551 and 553 of the slide rail 510, so that movement in the up, down, left, and right directions is restricted. By providing a plurality of movement restrictions in the mounting completed state, unexpected movement of the inner housing 410 can be suitably suppressed without using fixing means such as fasteners.

  As described above, since the ribs 425 and 426 are formed close to the top plate 11a of the housing 11, an illegal board is installed between the inner housing 410 and the top plate 11a of the housing 11. The space that can be used can be reduced. Further, since the guide ribs 470 and the boxes 480 and 490 are also arranged close to each other, it is possible to reduce the space in which the illegal board can be installed between the inner casing 410 and the side plates 11d and 11e of the casing 11. . In other words, it can be said that these ribs 425, 426, 470, 472 and boxes 480, 490 constitute a means for preventing installation of an unauthorized substrate. In order to more effectively prevent the installation of the unauthorized base, it is natural that the number of the ribs 425, 426, 470, 472, the number of the boxes 480, 490, and the size are increased. It 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 forward, and synthetic resin reel plates 652 to 654 (a left reel plate 652, a middle reel plate 653, and a right reel plate) accommodated in the case member 651. 654) and three reels 655 to 657 (left reel 655, middle reel 656, right reel 657) attached to the respective reel plates 652 to 654.

  At the upper front corners of both sides of the case member 651, a support fixing portion 658 protruding outward is provided, and a mounting hole 659 penetrating in the front-rear direction is formed substantially at the center of the front surface of the support fixing portion 658. Have been. Further, at the lower front corners of both sides of the case member 651, a support fixing portion 660 projecting outward is provided, and a mounting hole 661 penetrating in the front-rear direction is formed substantially at the center of the front surface. I have. These mounting holes 659 and 661 constitute mounting means for mounting the reel device 650 to the inner housing 410.

  These mounting holes 659 and 661 are formed corresponding to the protrusions 436 and 475 of the inner housing 410. By screwing screws into the screw holes 437, 476 of the projections 436, 475 with the projections 436, 475 fitted in the mounting holes 659, 661, the reel device 650 is fixed inside the inner casing 410. 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-shaped belt wound around the outer periphery thereof. A large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt (for example, 21 symbols). A stepping motor as a drive source is provided at the center of each of the reels 655 to 657, and the reels 655 to 657 are individually driven by the driving of the stepping motor, that is, each reel 655 to 657 is rotated independently.

  The reel plates 652 to 654 have a plate shape that stands vertically and extends in the front-rear direction. The reels 655 to 657 are rotatably supported on the right side of the reel plates 652 to 654. When the upper and lower ends of the reel plates 652 to 654 are fixed to the case member 651 by fasteners such as screws, a part of each of the reels 655 to 657 is exposed from the front opening of the case member 651. . The front side of each of the reel plates 652 to 654 is formed in a shape corresponding to a portion of each of the reels 655 to 657 that emerges from the case member 651.

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

  As another configuration, 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. A backlight (rear light emitting means) made of a fluorescent lamp or the like is provided on the inner peripheral side of each of the reels 655 to 657. With this backlight, each symbol attached to the outer peripheral surface of the reel is brighter than the rear. It is 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 an auxiliary effect in a game.

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

(Description of inner door 700)
The configuration of the inside 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 the front edge of the liquid crystal display device 711, and a main control device. A display control device 730 that performs a subordinate display control based on a command from the 770, a bearing 745 for attaching the inner door 700 to the inner housing 410, and closing the inner door 700 with respect to the inner housing 410. And a door lock 760 for holding the door in a closed state.

  The base 710 has a substantially square shape when viewed from the front, and a panel support (not shown) projecting forward is formed along the outer peripheral edge of the base 710 at the upper and lower portions of the front. The liquid crystal display device 711 includes a liquid crystal panel and a liquid crystal driver for driving the liquid crystal panel. Like the base 710, the liquid crystal display device 711 has a substantially square shape when viewed from the front. The liquid crystal display device 711 is formed so as to correspond to the base 710, and is mounted on the base 710 by being sandwiched between the upper and lower sides by a panel support. In addition, mounting portions are formed at four corners of the liquid crystal display device, and these mounting portions are fixed to the base 710 by fasteners such as screws.

  A front frame 720 made of synthetic resin is provided on the front side of the liquid crystal display device 711 so as to surround the liquid crystal display device 711. Is fixed to the base 710 by fasteners such as screws with the liquid crystal display device 711 sandwiched therebetween. The front frame 720 is formed in a substantially rectangular shape as a whole, and a shielding portion 721 extending upward from the liquid crystal display device 711 is provided at an upper portion thereof.

  A horizontally long rectangular display window 723 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 provided on the base 710. Accordingly, 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 formed of a transparent resin having no liquid crystal display, but may be formed of a through hole that penetrates back and forth.

  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 (a case base 733 and a 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 through the transparent case base 733 and the case cover 734. In the case base 733, mounting portions for mounting to the base 710 are formed at two places on the left and right. Through the case base 733, the display control device 730 is mounted on the upper rear surface of the base 710.

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

  The inner door 700 is openably and closably supported by the door support member 740 provided on the inner housing 410. As shown in FIG. 17, the door support member 740 has a long shape, is attached to a mounting base 460 formed on the right side plate portion 410e, and is fixed by fasteners (not shown) such as screws. Support shafts 741 and 742 are provided at two upper and lower positions of the door support bracket 740, and each of the support shafts 741 and 742 has a tapered shaft portion extending upward. The inner door 700 is rotatably supported by the door support bracket 740.

  On the other hand, a long bearing metal member 745 formed by bending a metal plate is fixed to a right end portion of the base 710 of the inner door 700 by a fastener (not shown) such as a screw. The bearing fitting 745 has supporting fittings 746 and 747 having upper and lower supporting holes corresponding to the supporting shafts 741 and 742 of the door supporting fitting 740 and having insertion holes into which the shaft portions of the supporting shafts 741 and 742 are inserted. Have been. By disposing the support fittings 746 and 747 above the 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. State. Accordingly, the inner door 700 is rotatably supported on the inner housing 410 about an opening / closing axis extending in the vertical direction that connects the two support shafts 741 and 742, and the rotation opens the front surface of the inner housing 410. The side can be opened and closed.

  A long hook receiving metal member 750 is fixed to the left side plate portion 410d of the inner housing 410 along an inner peripheral edge of the opening of the housing 11 by a fastener (not shown) such as a screw (see FIG. 18). . The hook receiving member 750 is provided with a pair of upper and lower hook receiving portions 751 and 752, and a guide piece 753 extending horizontally in the front-rear direction is formed by bending at a lower portion of the hook receiving member 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 metal 760 is provided on the back surface. The door locking bracket 760 includes a base frame 761 extending vertically and fixed to the base 710, a long interlocking rod 762 movably mounted on the base frame 761 in the vertical direction, and a hook receiving bracket. A guide block 763 made of a substantially rectangular parallelepiped and provided in correspondence with the guide piece 753 of 750 is provided. The interlocking rod 762 is provided with a pair of upper and lower hooks 765 and 766 having a hook shape corresponding to the hook receiving portions 751 and 752, respectively, when the inner door 700 is closed with respect to the inner housing 410. The hooks 765 and 766 are locked to the hook receiving portions 751 and 752, so that the inner door 700 is held in a closed state. 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 to perform vertical positioning. Therefore, the hooks 765 and 766 are reliably guided to the hook receiving portions 751 and 752 without shifting in the vertical direction.

  An operation piece 767 protruding below the inner door 700 is provided at the lowermost part of the interlocking rod 762. More specifically, the operation piece 767 includes a bent portion 768 formed by bending the lower end of the interlocking rod 762 at right angles toward the bearing bracket 745. By depressing the operation piece 767 (bending portion 768), the interlocking rod 762 is moved downward. Since each of the hooks 765 and 766 is provided with an urging member such as a coil spring for urging the hook to maintain the locked state, as described above, when the operation piece 767 is pressed down, the interlocking rod 762 moves downward. Then, the hooks 765, 766 are moved against the urging force of the urging member, whereby the locked state between the hooks 765, 766 and the hook receiving portions 751, 752 is released, and The closed state of the inner door 700 with respect to the body 410 is released.

  Since the operation piece 767 is formed by bending as described above, when the operation is performed from the inside of the face changing unit 400, that is, from the opening / closing side of the inside door 700, a finger is hooked on the operation piece 767 (bent portion 768). It can be easily pushed down. If the operation is performed from the outside of the face changing unit 400, since the bending direction of the operation piece 767 is opposite, it is difficult to catch a finger or the like, and it is difficult to push down. Therefore, when a tool or the like is incorrectly inserted from a gap between the housing 11 and the front door 12 close to the operation piece 767 in a state where the face changing unit 400 is completely mounted on the housing 11, the above-described outside It becomes an operation, and the pushing down operation becomes difficult. Further, when the tool enters as described above, the vertical portion of the operation piece 767 prevents access to the bent portion 768. In addition, since the approach direction of the fraudulent tool and the operation direction of the operation piece 767 are unlikely to be the same, the illegal operation becomes even more difficult.

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

  The main control device 770 includes a substantially horizontal rectangular 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 accommodating the main control board. ), And a movable base plate 774 that is removably mounted by sliding the case member. The case base 772, the case cover 773, and the movable base plate 774 each have a substantially horizontal rectangular shape so as to match the main board control board, and are formed of a transparent synthetic resin material such as a polycarbonate resin. Through these transparent case base 772, case cover 773, and movable base plate 774, the main control board disposed inside them is visible.

  The movable base plate 774 has a bottom plate portion 775 having a substantially long plate shape, and side plate portions 776 and 777 for supporting a case member are formed on long sides of the bottom plate portion 775. A step portion 778 is formed on one side of the short side of the bottom plate portion 775 so as to be continuous with the side plate portions 776 and 777, and a mounting port for slidingly mounting a case member on the opposite short side. 779 are formed. In this case, the case member is inserted from the mounting opening 779 and slid until it comes into contact with the step 778, so that the case member is mounted at a predetermined position on the movable base plate 774.

  A pair of bearings 780 and 781 are provided vertically along the short side of the movable base plate 774 on the same side as the stepped portion 778, and supports corresponding to these bearings 780 and 781. A support bracket (not shown) having a shaft is provided on the front and upper left of the back plate 410c. In such a configuration, the movable base plate 774 is rotatably attached to the support bracket by inserting the support shaft of the support bracket into the bearing portions 780 and 781 of the movable base plate 774 (see FIG. 6). .

  In the above configuration, by arranging the main control device 770 such that the electronic component mounting surface of the main control board faces forward, unauthorized confirmation of the main control board becomes easy. In addition, the movable base plate 774 is rotated about 90 degrees about the support shaft, so that the rotation distal end side of the main control device 770 is pulled toward the near side. In this state, the back side of the main control device 770 (the surface opposite to the electronic component mounting surface of the main control board) can be visually recognized, and whether various electronic components, electric wiring, and the like are not abnormal or improper can be checked. Confirmation can be performed.

  Incidentally, in the actual configuration of the slot machine 10, the front space of the main controller 770 is opened as shown in FIG. 6, FIG. 18 and the like, and there is no movement of the movable base plate 774 forward. There is no hindrance. Even if a device or mechanism that projects 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 with the opening of the inner door 700, and the rotating operation of the movable base plate 774 is also performed. No problem occurs. Also, even when the movable base plate 774 is rotated by about 90 degrees at the maximum, the upper opening 450 for avoiding interference with the main control device 770 is provided in the left side plate portion 410d, so that the rotation operation can be performed. There is no hindrance.

  The case base 772 and the case cover 773 are provided with a plurality of sealing portions (so-called caulking portions) (not shown) as sealing means for connecting these members. These sealed portions allow the case members 772 and 773 to be opened by accompanying destruction and the like. After the opening, the members that have been broken remain as opening history, so that the fact of opening can be confirmed by the opening history. It is possible. Further, a plurality of (two in the present embodiment) rectangular sealing seals S1 are attached to the case base 772 and the case cover 773 so as to straddle both. If the sealing seal S1 is once adhered and then peeled off, the adhesive is peeled off from the seal label and cannot be reapplied. If the sealing seal S1 is peeled off, there is no trace of the seal. It can be checked whether the main control board has been removed from the member. With such a configuration, in the case where the case member is illegally opened, for example, it is possible to detect an illegal act by confirming the sealed portion.

  On the other hand, when the case member is mounted on the movable base plate 774, a rectangular seal S2 is attached so as to straddle the movable base plate 774 and the case cover 773. The sealing seal S2, like the sealing seal S1, cannot be re-attached once the adhesive is peeled off after being pasted once it has been pasted. If the sealing seal S2 is peeled off, there is no trace of it. 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) for connecting the both. Whether or not the case member has been removed from the movable base plate 774 can also be confirmed based on the destruction history of these sealing portions.

  As shown in FIGS. 18 to 20, above the reel device 650 (on the front side of the accommodation recess 442), a long plate-like partition plate 791 which is passed between the left side plate portion 410d and the right side plate portion 410e is horizontally. It is provided in. A relay board 790 for electrically connecting the main controller 770 to 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. Is covered by the case body 792. The case body 792 is formed of a transparent synthetic resin material such as a polycarbonate resin, and the relay board 790 disposed inside the case body 792 is visible through the case body 792. 13 to 19, it is difficult to confirm the relay board 790, so refer to the perspective view of FIG.

  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. 27A is a partially enlarged view of FIG. 9, and FIG. 27B is a cross-sectional view taken along line AA of FIG.

  A substantially rectangular metal base plate 445 extending to the left and right is fixed to the upper portion inside the back plate 11c by fasteners such as screws. A printed board 813 is provided. The board base plate 445 is provided with legs 446 extending forward to attach the printed board 813 to the left and right ends of the printed board 813. It is fixed to its leg 446 by fasteners such as screws with a space between them.

  The housing connector 811 has a substantially rectangular shape that is horizontally long when viewed from the front of the slot machine 10, and has a box-shaped connector main body 811b having an opening (insertion opening 811a) at the front and a connector main body 811b at the back of the connector 811. And overhang portions 815 that protrude left and right on both sides. The housing connector 811 is arranged in a state where the back side of the projecting 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, and the space provided between the printed board 813 and the board base plate 445 and the relief hole 817 are provided. Thus, the harness is connected to the rear side of the housing connector 811.

  Further, a gate-shaped support member 819 that is open upward when viewed from the front of the slot machine 10 is provided so as to surround both sides and a lower portion of the connector main body 811b. On both sides of the support member 819, connector fixing portions 821 for fixing the projecting portion 815 of the housing connector 811 in a state sandwiched between the supporting member 819 and the printed circuit board 813 are formed. The fixing structure of the housing connector 811 will be described in detail. Fasteners such as screws (not shown) are attached to 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 communication 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 corresponding to the through hole. I have. That is, the printed board 813, the housing connector 811, and the support member 819 are attached to the board base plate 445 in a state where they are integrally connected. Note that the right housing connector 812 shown in FIG. 9 is also fixed to the board base plate 445 by the printed board 814 and the support member 820.

  In addition, a lower supporting portion 823 protruding forward along the bottom of the housing connector 811 is provided below the supporting member 819, and a front end thereof faces an insertion opening 811 a of the housing connector 811. An inclined guide surface 827 is formed, and the inclined guide surface 827 will be described later in detail.

(Description of face change connectors 841 and 842)
Next, the face change connectors 841 and 842 will be described. As shown in FIGS. 14 and 16, the face change connectors 841 and 842 are juxtaposed to the left and right at positions corresponding to the housing connectors 811 and 812 at the bottom of the housing recess 442 of the back plate 410c. The face changing connectors 841 and 842 are in a state where the insertion portions 841 a and 842 a to be inserted into the insertion openings 811 a and 812 a of the housing connectors 811 and 812 face rearward in the mounting / removing direction of the inner housing 410 (surface changing unit 400). Are attached to the accommodation recess 442 via a long plate-shaped support 843. The accommodation recess 442 is formed with a horizontally long hole 443 penetrating inward and outward corresponding to the face change connectors 841 and 842, and through the hole 443, the face change connectors 841 and 842 and the main control are formed. The device 770 and the like are connected by a harness (not shown).

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

  Since each of the left and right face change connectors 841 and 842 has the same attachment structure, the attachment structure of the left face change 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 sectional view taken along line BB of FIG.

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

  The support body 843 is provided with fastening holes 847 penetrating inward and outward at positions corresponding to the round holes 846, and screws 848 are inserted from behind the round holes 846 (to the right in FIG. 28B). The face change connector 841 is attached by screwing the tip of the 848 into the fastening hole 847. The outer diameter of the shaft portion 849 of the screw 848 that forms the insertion portion with respect to the round hole 846 is formed smaller than the inner diameter of the round hole 846. 850 and the support 843 sandwich it back and forth. In other words, the housing connector 841 itself is not fixed by the screw 848, but is held in a state where the 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 in which the inner wall of the round hole 846 contacts the shaft 849 of the screw 848, that is, within a gap formed by the round hole 846 and the shaft 849. . Note that by setting the outer diameter of the washer 850 in consideration of the movable range of the housing connector 841, the housing connector 841 can be prevented from falling off the screw 848. In the present embodiment, the axial direction of the screw 848 is configured to be the same as the mounting direction of the inner housing 410, and the housing connector 841 is mounted in all directions orthogonal to the mounting direction of the inner housing 410. About 2 mm. When the face changing connector 841 is detached from the housing connector 811, the face changing connector 841 is located at the lower limit within the movable range with its own weight. More specifically, since the screw 848 and the round hole 846 are formed concentrically, the lower limit position is uniquely determined. Thus, 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, 842 are coupled are unified, so that the inner housing 410 (surface changing unit 400) can be mounted. The surface changing connectors 841 and 842 and the housing connectors 811 and 812 can be coupled with the pushing operation into the housing 11. Similarly, the face changing connectors 841 and 842 and the housing connectors 811 and 812 can be separated by a pull-out operation of the inner housing 410. Therefore, in the replacement work of the surface changing unit 400, the operator does not need to separately perform an operation of inserting and connecting the connectors 811, 812, 841, 842, and separating the connectors by separating them. Thereby, it is possible to efficiently perform the replacement work of the surface changing unit 400.

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

  By providing the guiding inclined surface 827 and the guiding inclined surfaces 835 and 836 as connector guiding means, the surface changing connectors 841 and 842 movably provided as the surface changing unit 400 is pushed into the housing 11. 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 abut against the guide inclined surface 827, whereby the housing connectors 811 and 812 are connected. Are guided by the insertion openings 811a and 812a, and are further pushed in, thereby being urged to move vertically and horizontally by the guide inclined surfaces 835 and 836, and guided to a predetermined coupling position. Thus, the position adjustment of the face changing connectors 841 and 842 with respect to the housing connectors 811 and 812 is completed. Therefore, in the replacement work of the face changing unit 400, the worker does not need to adjust the insertion positions of the connectors 811, 812, 841, and 842, so that the replacement work of the face changing unit 400 can be performed more easily. It becomes possible. Further, as described above, the housing connectors 811 and 812 can be moved in any direction such as up and down and left and right even in the coupled state, so that when the face changing unit 400 is replaced, a force is applied in a direction different from the attaching / detaching direction. Even if it is added, it is possible to prevent the concentration of the force at the connection points of the connectors 811, 812, 841, 842. This can prevent the connectors 811, 812, 841 and 842 from being damaged. Further, in the present embodiment, the face changing connectors 811 and 812 are configured to be movable within a predetermined gap, and the connectors are configured to be movable in a state where the connectors are regulated by a regulating member such as a spring. Not necessarily. That is, the position adjustment is not performed by the deformation of the regulating member. For this reason, a load is hardly generated in the portion that restricts the movement of the connector, and it is possible to suitably cope with repeated use.

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

  In this manner, the face change connectors 841 and 842 are inserted into the housing connectors 811 and 812, so that the face change connectors 841 and 842 and the housing connectors 811 and 812 are electrically connected. A control signal from main controller 770 is output to hopper device 110 and the like, and power from power supply box 100 is supplied to main controller 770 and 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 in the back of the housing, the force of pushing the surface changing unit is reduced by using frictional resistance. When the face change connectors 841 and 842 violently collide with the housing connectors 811 and 812, it is possible to preferably suppress problems such as breakage of the connectors 811 and 812 and 841 and 842.

  Further, when the face changing unit 400 is attached to the housing 11 (the connectors 811, 812, 841, 842 are connected), the shape of the housing recess 442 is changed to the printed circuit boards 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 face changing unit 400 and the back plate 11c of the housing 11 can be arranged close to each other, and the depth inside the housing 11 can be effectively used, and each connector 811 can be used. , 812, 841, 842 can be shielded from the surrounding gaps, thereby preventing improper acts on the connectors of the connectors 811, 812, 841, 842.

(Explanation of the completed state as the face 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 mounted inside the inner housing 410, and a relay board 790 is mounted 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 that also serves as a liquid crystal display is attached to the front of the inner housing 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 face changing unit 400. More specifically, out of a large number (21 in this embodiment) of symbols on the outer circumference of each of the reels 655 to 657, three symbols for each reel can be visually recognized through the display window 723. ing.

  Further, a design plate (not shown) on which a design of a character or the like unique to the gaming machine is provided 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 when the inner door 700 is closed by the inner housing 410. Further, the shielding portion 721 is provided in front of the main control device 770, and it is possible to suppress the inconvenience of directly viewing the main control board 771 from outside in front of the face changing unit 400. That is, the inner door 700 is provided so as to cover almost the entire opening of the inner housing 410 in a front view of the surface changing unit 400. It can be said that the inner door 700 constitutes shielding means for shielding the inside of the inner housing 410 from the outside.

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

(Explanation of replacement work of face changing unit 400)
Here, the replacement work of the face change unit 400 at the time of model change in the game hall or the like will be described. In this case, first, the front door 12 is unlocked by using a prescribed operation key K (see FIG. 3), and the front door 12 is opened to a predetermined angle or more. Next, by depressing the operation piece 767 provided at the lower left of the inner door 700, the locked state of the hooks 765 and 766 that lock the inner door 700 to the inner housing 410 is released. Then, after the inner door 700 is opened to a predetermined angle or more, the locked state of the surface changing unit 400 is released by tilting the operation unit 615 of the lever member 610 provided in the surface changing unit 400 to the front side. Then, only the inner door 700 is closed. Then, the face changing unit 400 is pulled toward the front side along the support rail 300, and when the inner casing 410 is hooked (once stopped), the front side is raised by about 10 °. If it is drawn to the near side again and comes into contact with the resin piece 330 just before detachment, the same-surface changing unit 400 is detached by being further attracted to the near side.

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

  At the time of the replacement work, connectors 811, 812, 841, 842 for electric wiring connecting the surface replacement unit 400 and other various members (the power supply box 100, the hopper device 110, etc.) are pushed by the pushing operation of the surface replacement unit 400. Since the connection is established and the connection is released by the pulling operation, the connection and disconnection operations of the connectors 811, 812, 841 and 842 do not need to be separately performed.

(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 a face changing unit 400 are housed inside a housing 11, and a front door 12 is provided so as to close an opening of the housing 11. The liquid crystal display device 711 of the face 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 through the display window 723 of the face changing unit 400. The configuration allows the part to be viewed.

  As shown in FIG. 29 (schematic diagram showing a state where the face changing unit is mounted on the side surface of the slot machine), the inner casing 410 of the face changing unit 400 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 disposed forward of the boundary B2 between the front door 12 and the housing 11. The hook receiving portions 221 and 222 of the hook receiving bracket 220 are provided behind the boundaries B1 and B2. In other words, the hook 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 hook receiving portions 221 and 222 are provided behind the gap and 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 is difficult to open the front door 12 by infiltrating a wire, a film, or the like from a gap (boundary B2) at a portion facing the rear end of the outer periphery. Therefore, fraudulent acts can be suppressed.

  The back plate portion 410c has a substantially planar shape 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 face changing unit 400 is mounted in the housing 11. The casing 11 is formed so as to be substantially parallel to the casing 11, so that the depth region of the housing 11 can be used to the maximum. 9 and 15, the side plates 410d and 410e and the housing 11 are formed to be substantially parallel to the inner peripheral surfaces (side plates 11d and 11e) of the housing 11, respectively. By doing so, the area in the left-right direction of the housing 11 can also be effectively used.

  The accommodation recess 452 of the inner housing 410 is formed in a size that does not cause interference between the front door 12 and the inner housing 410 when the face changing unit 400 is moved in the mounting direction. More specifically, if the front door 12 is opened at a predetermined angle or more without being removed, no interference occurs. Thus, the worker can perform the push-in operation and the pull-out operation straight in the mounting direction without worrying about interference with the front door 12 with the front door 12 being mounted. Therefore, workability can be improved.

  As shown in FIG. 5, in the present embodiment, the opening / closing base axes of the front door 12 provided on the housing 11 and the inner door 700 provided on the inner housing 410 are provided on left and right opposite sides, respectively. The configuration was adopted. Therefore, in order to open the inner door 700 and access the main controller 770 mounted inside the inner housing, it is necessary to open the front door 12 by a predetermined angle or more. That is, in order to perform unauthorized access to the main controller 770, the front door 12 needs to be widely opened, so that it is difficult to form a blind spot from the staff of the game arcade or the surveillance camera, thereby preventing illegal acts. . Further, even if it is performed, it is easy to catch by the staff of the game hall or the surveillance camera, so that it is possible to easily detect the fraud.

  Further, 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 to operate the operation piece 767 (FIG. 4). That is, it is difficult to slightly open the front door 12 and release the locked state of the inner door 700. Therefore, access to main controller 770 from the gap with both doors 12, 700 slightly opened can be suppressed.

  As described above, the inside of the face changing unit 400 is preferably restrained from unauthorized access from the outside. For this reason, by accommodating the components of the slot machine 10 that are likely to be fraudulent, inside the face changing unit 400, it is expected that fraud on these components is suppressed. In the present embodiment, the power switch 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 medal advance, but this is changed. However, the reset switch 102 and the setting key insertion hole 103 may be provided inside the face changing unit 400, for example, in the main control device 770. Thus, it is possible to suppress fraud such as changing the pitching setting of the slot machine 10 using a fraudulent tool such as a wire.

  As shown in FIG. 4, a configuration including hook 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 plates 410 d and 410 e of the face changing unit 400. And That is, the hook receiving portions 221 and 222 are arranged in a region between the surfaces. Thus, even if the hook is released by using a wire, a cellophane, or the like, the allowable movement range of the hook can be restricted, and the unauthorized opening of the front door 12 can be suppressed.

  As shown in FIG. 6, in a lever member 610 for performing an unlocking operation of the surface changing unit 400, an 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 face changing unit 400 is in a space between the side plates 11d and 11e of the housing 11 and the side plates 410d and 410e of the face changing unit 400. For this reason, it is difficult and time-consuming to insert a finger, wire, or the like into the above space for the purpose of canceling fraud. It is possible to do. On the other hand, since the external operation is also 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 external state. , 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 face changing unit 400. It is good also as composition which can control operation.

  The housing 11 and the face changing unit 400 are provided with a plurality of sealing portions (so-called caulking portions) as sealing means for connecting them. More specifically, the unit-side round hole 413 provided in the surface changing unit 400 (specifically, the reinforcing plate 411) and the housing-side round hole (not shown) provided in the housing 11 are separated by a swaging band (not shown). Connected in an impossible state. These seal portions (bands for caulking) allow the face changing unit 400 to be removed by causing destruction or the like. After removal, the members that have been destructed or the like remain as an opening history. This allows confirmation of the fact of opening. With such a configuration, if the face change unit 400 is illegally removed, etc., it is possible to detect an improper act by confirming the sealing portion.

(Description of electrical configuration)
Next, an electrical configuration of the slot machine 10 will be described with reference to a block diagram of FIG.

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

  On the input side of the main controller 770, a start detection sensor 921 for detecting the operation of the start lever 45, stop detection sensors 922, 923, 924 for individually detecting the operation of each of the stop switches 50 to 52, and the medal shooting device 30 An inserted medal detection sensor 925 for detecting inserted medals, a bet detection sensor 926, 927 for individually detecting the operation of each of the bet switches 40 and 41, a settlement detection sensor 928 for detecting the operation of the settlement switch 55, and each reel 655 to 655. Reel index sensor 929 for individually detecting the rotation position (origin position) of 657, payout detection sensor 930 for detecting medals paid out from hopper device 110, reset detection sensor for detecting operation of reset switch 102 provided in 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.

  Note that 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 such that medals can pass in one row. A first sensor is provided in the storage passage 32, and the second sensor and the third sensor are close to each other on the downstream side more than the width of the medal (at least at the same time, a state in which the same medal is detected at the same time). The first to third sensors constitute an inserted medal detection sensor 925. Main controller 770 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, it is considered that there is a medal clogging or an improper operation, and an error occurs. When an error occurs, an error is notified and the 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 and off, and both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. It is determined that the medal has been taken normally only when the order is such that only the third sensor is on and both the second and third sensors are off and the time to shift to each on / off switching is within a predetermined time. Otherwise, an error occurs. The reason for this is to prevent the medals from being misrecognized as inserted medals by reciprocating the medals near the inserted medal detection sensor 925 in addition to the clogging of medals in the storage passage 32.

  A power failure monitoring circuit 902b provided in the power supply 902 is connected to the input side of the main controller 770 via an input / output port 904. The power supply unit 902 includes a power supply unit 902a for supplying drive power to each electronic device of the slot machine 10 including the main control unit 770, the above-described power failure monitoring circuit 902b, and the like.

  The power failure monitoring circuit 902b monitors the power supply cutoff state and generates a power failure signal when the power supply is cut off by a power switch provided in the power supply box as well as at the time of the power failure. Therefore, the power failure monitoring circuit 902b monitors the stabilized drive voltage of DC 12 volts output from the power supply unit 902a in this example, and determines that the power has been cut off when the drive voltage drops to, for example, less than 10 volts. And outputs 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 the power failure signal and executes a power failure process.

  Even if the output voltage drops to less than 22 volts, the power supply unit 902a outputs a stabilized voltage of 5 volts used as a drive voltage in a control system such as the main controller 770. As the time during which the stabilized voltage is output, a time sufficient for executing the power failure process by main controller 770 is secured.

  On the output side of the main controller 770, 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), such as stepping motors for rotating the reels 655 to 657, and the like. For example, an external centralized terminal board 945 capable of transmitting information is 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 behind the speaker units 82 and 83, and the liquid crystal display device 711. It has a board on which a CPU, a ROM, a RAM and the like are integrated. Then, after receiving a signal from the main control device 770, the display control device 730 independently drives and controls various lamps, various speakers, and the liquid crystal display device 711. Accordingly, the display control device 730 is a sub-board that executes auxiliary control in relation to the main control device 770 that is a main board that controls and manages the game. That is, by providing a sub-board for sounds, lamps, and displays related to indirect games, the burden on the main board is reduced.

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

  The RAM 953 has a configuration in which a backup voltage is supplied from the power supply device 902 and data can be held (backed up) even after the power of the slot machine 10 is cut off, and the RAM 953 temporarily stores various data and the like. A backup area is provided in addition to a memory and an area for storing.

  In the backup area, when the power is cut off due to the occurrence of a power failure or the like, the stack pointer, each register, and I when the power is cut off (including the power cut by operating a power switch provided in the power supply box 100) This area is used to store values such as / O and the like. When the power failure is stopped (including power-on by operating a power switch. The same applies hereinafter), the state of the slot machine 10 is determined based on the information in the backup area. It can return to the state before the power was turned off. Writing to the backup area is executed when the power is turned off by the process at the time of power failure, and restoration of each value written to the backup area is executed in the main process when the power is turned on. The NMI terminal (non-maskable interrupt terminal) of the CPU 901 is configured to receive a power failure signal from the power failure monitoring circuit 902b when the power is shut down due to the occurrence of a power failure or the like. An NMI interrupt process as a flag generation process is immediately executed.

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

  As shown in FIG. 24 and the like, the inner casing 410 (the face changing unit 400) projects forward from an opening of the casing 11 in a state of being attached to the casing 11. Therefore, when the front door 12 is closed in the housing 11, the boundary 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 improper act that is performed via the boundary portion, such as erroneously operating a sensor or the like inside the gaming machine using an illegal tool such as a wire. For example, it is possible to suppress a fraudulent act of repeatedly playing a game without actually inserting medals by erroneously operating a sensor for detecting insertion of medals by an inserted illegal tool.

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

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

  Since the main controller 770 is mounted inside the inner casing 410 where unauthorized access is difficult, it is possible to suitably protect the main controller 770 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 preferably suppress the illegal change of the setting for adjusting the medal ball in the gaming machine. .

  The inner casing 410 has a box shape, and has no gap between the left and right side plates 410d and 410e and the top plate 410a. For this reason, it becomes possible to shield even at the upper right and left 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 those corners.

  When the inner housing 410 is completely mounted on the housing 11, the boxes 480 and 490 provided in the housing 11 can prevent the inner housing 410 from shifting left and right inside the housing 11. That is, it is possible to prevent the clearance between the side plate of the housing and the side plate of the unit main body from being increased on either side of the boundary between the housing 11 and the front door 12 due to the bias of the inner housing 410. can do. Even if the slot machine 10 is shaken or the like to cause a displacement of the inner casing 410 to create a portion where an illegal tool can easily enter, even if the inner casing 410 is moved left and right as described above. Because it is regulated, this can be prevented.

  In addition, since the trajectory when mounting the inner casing 410 is stabilized by the boxes 480 and 490, for example, the inner casing 410 is tilted or shifted left and right, so that a door support provided around the opening of the casing 11 is provided. The inconvenience of hitting the metal fitting 200 or the like can be suppressed.

  Further, the inner housing 410 is moved by the lever member 610 on the inner housing 410 side and the support rail 300 (more specifically, the notch 352) on the housing 11 side being locked when the mounting is completed. Limited. Thus, for example, it is possible to suppress a disadvantage that the inner casing 410 is displaced after the mounting is completed. It is assumed that the cheating person shifts the inner housing 410 by shaking the slot machine 10 in order to twist out a gap for inserting a fraudulent tool or the like, so that the side plate portions 410d and 410e of the inner housing 410 are connected to the housing 11. Even if it is attempted to move the inner housing 410 away from the boundary with the front door 12, this can be prevented because the movement of the inner casing 410 is suppressed.

  When the inner housing 410 is pushed into the mounting completed position, the inner housing 410 is shifted to a locked state. That is, since no separate operation is required for shifting to the locked state, the inconvenience that the deterrence against fraud is reduced by the operator forgetting the operation is less likely to occur.

  As a locking device for the front door 12, hooks 231 and 232 are provided on the front door 12, and hook receiving members 220 (specifically, hook receiving portions 221 and 222) are provided on the housing 11. The upper hook receiving portion 221 is provided on the left side plate 11 d of the housing 11 at a position facing the left side plate portion 410 d of the inner housing 410. Therefore, it is difficult to access the hook receiving portion 221 from the side of the slot machine 10. Even if a wrongdoer inserts an illegal tool such as a wire from the boundary portion between the housing 11 and the front door 12 and tries to access the hook receiving portion 221 illegally, this can be made difficult. it can.

  Each of the hooks 231 and 232 is independently rotatable to the locked position, and the hooks 231 and 232 are connected by a connecting member and move in conjunction only by operating the operation key K by a hall manager or the like. Configuration. Therefore, for example, even if the lower hook 232 is unlocked for the purpose of illegally opening the front door 12, it is possible to suppress the inconvenience that the upper hook 231 is unlocked in conjunction with the unlocking. Since it is difficult to unlock the upper hook 231 at least, the front door 12 is locked at two locations above and below, so that the front door 12 can be prevented from being lifted up and illegal opening of the front door 12 can be suitably suppressed. .

The rotating shafts of both hooks 231 and 232 are provided near the boundary between front door 12 and housing 11. Thus, it is difficult to access the hooks 231 and 232 other than the rotation shaft portion via the boundary portion. For example, even when the wrongdoer accesses the hooks 231 and 232 by inserting an unauthorized tool such as a wire from the boundary portion between the housing 11 and the front door 12, the access portion is limited to the vicinity of the rotating shaft portion. You. Even if it is attempted to move the hooks 231 and 232 to the unlocking position with the illegal tool hooked on the hooks 231 and 232, a force acts on a position near the fulcrum of the hooks 231 and 232 and the hooks 231 and 232 are moved. 232 is difficult to rotate. Therefore, it is not easy to separate the hooks 231 and 232 from the hook receiving portion, and the unauthorized release of the locked state can be more appropriately suppressed.
For this reason, even if the wrongdoer inserts an illegal tool such as a wire through the gap at the boundary between the housing 11 and the front door 12 and hooks the hooks 231 and 232 to move to the unlocking position, It becomes difficult except for access to parts other than the moving shaft part or its vicinity. That is, even if it is attempted to rotate the hooks 231 and 232 near the fulcrum, it is difficult to transmit a sufficient force, and it is not easy to separate the hooks 231 and 232 from the hook receiving portions 221 and 222. . Therefore, unauthorized release of the locked state can be suppressed more appropriately.

  As shown in FIG. 1 and the like, the front door 12 is provided with a projecting portion 15 projecting toward the housing 11. Thereby, the rigidity of the front door 12 can be increased. The front door 12 tends to be opened and closed frequently for maintenance (power on / off, replenishment of medals, etc.) and the like, and the rigidity is improved as described above, so that deformation of the front door 12 due to work or the like can be prevented. Can be suppressed. Further, by storing a part of the inner housing 410 and the inner door 700 in the overhang portion 15, the reel device 650 (specifically, the reels 655 to 657) mounted thereon and the front of the slot machine 10 of the liquid crystal display device 711. Visibility from the user can be secured. That is, it is possible to improve the rigidity of the front door 12 and ensure 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 face changing unit 400. By sharing the weight in this way, it is possible to reduce the weight burden generated on the front door 12. When the frequency of opening and closing the front door 12 and the inside door 700 during maintenance and the like is compared, it is considered that the frequency of the front door 12 increases. Therefore, as described above, by suppressing the increase in the weight of the front door 12, the workability is improved. Improvement is expected. Further, since the weight burden on the front door 12 is suppressed, it is possible to reduce variations in the construction of the front door 12. Thereby, it is possible to preferably avoid the inconvenience that the boundary between the front door 12 and the housing 11 is expanded.

  The present invention is not limited to the description of the above-described embodiment, and may be implemented as follows, for example.

  (A) In the above-described embodiment, the protruding amount of the inner housing 410 constituting the surface changing unit 400 from the opening of the housing 11 is substantially equal at the same height on the left and right. This may be changed so that the left or right protrusion amount is larger than the other protrusion amount. Further, as shown in FIG. 24, the projecting amounts of the left and right side plate portions are configured to gradually increase from the upper side to the lower side. However, the present invention is not limited to this, and the protrusion amounts are gradually increased from the upper side to the lower side. May be configured such that the protrusion amount is the same at any height.

  (B) In the above embodiment, as shown in FIG. 10 and the like, the top plate 410a of the inner housing 410 (replacement unit 400) does not project forward from the opening of the housing 11, and With the reinforcing plate 411 attached to the portion 410a, the reinforcing plate 411 is configured to protrude forward from the opening of the housing 11. By changing this, the top plate portion 410a may be configured to protrude forward from the opening. 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 housing 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 between the top plate 11a and the top plate portion 410a so as to be separated left and right. By providing a total of four speakers at the lower part and the upper part of the slot machine 10, diversification of sound effects can be achieved.

  (C) In the above embodiment, as shown in FIG. 13, the reinforcing plate 411, the door support fitting 740, and the hook receiving fitting 750 are provided outside the inner casing 410. This may be changed as follows. That is, the reinforcing plate 411, the door support member 740, and the hook receiving member 750 may be provided inside the inner casing 410. In this case, the rigidity around the opening of the inner housing 410 can be easily improved. In addition, a configuration in which the reinforcing plate 411, the door support fitting 740, and the hook receiving fitting 750 are not provided is also possible.

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

  (E) In the above embodiment, the inner door 700 is mounted forward of the opening of the inner housing 410, but this is changed so that the inner door 700 is mounted so as not to protrude forward from the opening of the inner housing 410. You may. This makes it possible to adopt a configuration in which the boundary between the inner housing 410 and the inner door 700 is not exposed to the side of the slot machine 10 (becomes forward). That is, the boundary between the housing 11 and the front door 12 and the boundary between the inner housing 410 and the inner door 700 do not face in the same direction. Even if an illegal 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. Security against fraud inside the body 410 can be improved.

  Further, in this case, the front door 12 is provided with a projecting plate portion extending inside the projecting portion 15 and opposed to the projecting portion 15, and the projecting portion 15 and the projecting plate portion are doubled inside and outside. The front end of each plate portion 410a, 410d, 410e may be stored between the overhang portion 15 and the protruding plate portion with the front door 12 closed. With such a configuration, it is possible to more appropriately suppress intrusion of an illegal tool such as a wire.

  (F) The number of the boxes 480 and 490 and the size in the front-back and up-down directions (excluding the left-right thickness direction) are arbitrary. For example, by increasing the number of boxes 480 and 490, it is possible to reduce a gap (dead space) between the housing 11 (specifically, the side plates 11d and 11e) and the inner housing 410 (specifically, the side plates 410d and 410e). In addition, it is possible to more suitably suppress the fraud such as an improper substrate being installed in the dead space.

  Further, a configuration without the guide rib 470 is also possible. However, in this case, since the guide rib 470 is formed with the inclined surface 471 to prevent the boxes 480 and 490 from being caught, the side plates of the boxes 480 and 490 may be curved inwardly instead. It is desirable to configure so that As a result, workability in attaching and detaching the unit can be ensured.

  (G) In the above-described embodiment, the support rails 300 are provided separately on the left and right sides of the housing 11 and are formed of different members. This may be changed as follows. That is, the support rail may be formed of one member. For example, a flat supporting member may be provided so as to bridge between both side plates 11d and 11e of the housing 11. Thus, a support function of supporting the inner housing 410 (the surface changing unit 400) to the support member and a reinforcing function of improving the rigidity of the housing 11 can be provided.

  (H) In the above-described embodiment, the surface changing unit 400 is configured to be in the locked state (cannot be taken out) in accordance with the pushing operation of the surface changing unit 400 into the housing 11. The replacement unit 400 may be configured to be unable to be taken out by a separate operation after the mounting of the 400 is completed. For example, a lock fitting is provided on the housing 11 side, a hook fitting is provided on the face changing unit 400 side corresponding to the lock fitting, and the worker hooks the hook fitting on the locking fitting after the mounting of the face changing unit 400 is completed. By doing so, it is preferable that the face changing unit 400 be configured so as not to be taken out.

  (I) In the above embodiment, the hook receiving metal member 220 for closing the front door 12 is opposed to the side plate portion 410e of the inner housing 410 on the right side plate 11e of the housing 11 (open / close end of the front door 12). Part. By changing this, it is also possible to provide the hook receiving fitting at a portion of the top plate 11a of the housing 11 facing the top plate portion 410a of the inner housing 410. However, in this case, it is desirable to provide the hook receiving portion of the hook receiving bracket near the open / close free end of the front door, in consideration of suppressing the lifting of the front door 12 from the housing 11 side.

  (J) In the above embodiment, two sets of hooks 231 (232) and hook receiving portions 221 (222) constituting the locking device of the front door 12 are provided, but the number of 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 that at least one set (one hook receiving portion) is provided 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 embodiment, the hooks 231 and 232 of the front door 12 have their rotation axes oriented in a substantially horizontal direction (left and right direction), so that the hooks 231 and 232 on the housing 11 side can be moved. Although it is configured to rotate up and down, this may be changed as follows. In other words, the hook may be configured to turn left and right with respect to the hook receiving portion on the housing 11 by turning the rotation axis of the hook in a substantially vertical direction (up-down direction).

  (L) In the above embodiment, the inner casing 410 is integrally molded from a synthetic resin using a mold. However, this is changed, and after the respective plates constituting the inner casing 410 are separately provided. It is also possible to form the inner casing 410 by connecting the respective plate parts by fixing means such as bonding or fastening means such as screws. Further, the material of the unit body is not limited to a synthetic resin, and a 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 formed by a continuous surface that inclines toward the inside of the inner housing 410 from the front to the rear. Although the configuration is changed, the outer surfaces of the side plate portions 410d and 410e may be configured as a discontinuous uneven surface having a step shape from the front portion to the rear portion. In such a case, the upright amount of the guide ribs 470 formed on the side plate portions 410d and 410e may be increased stepwise (stepped) from the front to the rear.

  (N) In the above-described 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 (in the high friction section). Specifically, the lower guide portion 320) and the slide rail 510 (specifically, the supported portion 512) are brought into surface contact, but this is changed as follows.

  For example, the support rail 300 and the slide rail 510 are configured to be held in a surface contact state in both the low friction section and the high friction section. At least one of the surface roughnesses 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 come into contact with each other in the low friction section and increasing the surface roughness of the parts that come into contact with each other in the high friction section, an optimum frictional resistance considering the work load and the braking force is given. can do. The surface roughness and the surface treatment of the support rail 300 and the slide rail 510 may be given a difference in surface roughness.

  (O) In the above-described embodiment, a portion having low friction and a portion having high friction are provided at a 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. This may be changed 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. A portion where low friction and a portion where high friction is provided may be provided in a portion where the inner housing 410 contacts the inner housing 410.

  For example, a housing-side contact member that extends back and forth and contacts the inner housing 410 is provided on at least one of the inner surfaces of both side plates 11d and 11e of the housing 11 and the inner housing 410. It is preferable to set two high and low friction sections (regions) that cause different frictional resistance with the body 410. In this case, by applying a surface treatment such as coating to a portion of the inner housing 410 (specifically, each of the plate portions 410a, 410d, and 410e) and the housing-side contact member that come into contact with each other, high and low friction sections having different friction resistances can be formed. It can be easily realized.

  (P) In the above embodiment, the lever members 610 as “unit-side locking tools” are provided on both the left and right sides of the surface changing unit 400 (specifically, the inner casing 410). May be provided only for Desirably, the lever member 610 is provided on the opening / closing base end side of the inner door 700, that is, on the side provided with the door support metal member 740 that supports the inner door 700 (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 part of each of the side plates 410d and 410e of the inner casing 410, but this is changed and each of the side plates 410d and 410e is changed. May be provided on the upper part. For example, although the left lever member 610 is configured to be housed together with the support rail 300 in the housing recess 452 formed below the left plate portion 410d, it is located 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 housing 410 is supported by the support rail 300 of the housing 11, as described above, the movement of the inner housing 410 is suppressed at the upper portion of the inner housing 410, so that the inner housing 410 in the mounted state is completed. 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, this may be changed, and the display control device 730 may be mounted on the inner housing 410 side of the surface changing unit 400. The display control device 730 is unique for each model and therefore needs to be replaced according to the model change, whereas the liquid crystal display device 711 is not necessarily replaced because there is a possibility that it can be used regardless of the model change. . The liquid crystal display device 711 is provided on the inner door 700 which is detachably provided to the inner housing 410, and the display control device 730 is provided on the inner housing 410 which is a model change replacement target. Thus, the liquid crystal display device 711 can be reused together with the inner door 700.

  (S) In the above-described embodiment, the liquid crystal display device 711 (a so-called donut type liquid crystal device) having substantially the same size as the front surface of the inner door 700 and forming a rectangular ring is provided as the “auxiliary display device”. . That is, a liquid crystal display device smaller in size than the front surface of the inner door 700 may be provided. For example, the liquid crystal display device may be arranged on the upper, lower, left, or right of the reel device 650. Further, as the auxiliary display device, a configuration in which a dot matrix display device other than the liquid crystal display device is mounted, for example, or a configuration in which the auxiliary display device is not mounted can be adopted.

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

  (U) The front door 12 provided on 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 upper and lower parts. In this case, the opening of the housing 11 is closed by an upper door and a lower door which are provided vertically, and the upper and lower doors are attached to the housing 11 so as to be openable and closable. Further, the upper door may be attached to the inner casing 410, and the lower door may be attached to the casing 11 so as to be openable and closable.
