  First, the invention that can be extracted from the present embodiment will be described while showing effects and the like as necessary.

Means 1. A casing (casing 11) opened forward of the gaming machine;
A pattern display device (reel device 650) having an orbiting body (reels 655 to 657) on which plural kinds of patterns are disposed in the circumferential direction and displaying the pattern variably by rotating the orbiting body A display unit (face changing unit 400) mounted on the housing 410),
A support member (support rail 300) which is provided inside of the housing and on both left and right side plates (the left side plate 11d and the right side plate 11e) and movably supports the unit main body in the case;
A gaming machine comprising: a supported member (rail unit 500) having a rolling member (roller 540) provided on the unit main body and rolling on the support member when the unit main body is attached and detached;
The unit main body has left and right side wall portions (left side plate portion 410d, right side plate portion 410e), and a part of at least one side wall portion of the both side wall portions is recessed to form a recess. A gaming machine provided with a housing portion (housing concave portion 452) for housing the supported member.

  In the gaming machine of the means 1, the display unit formed by mounting the pattern display device on the unit main body is configured to be detachable from the housing. When attaching and detaching the unit main body, the unit main body is pushed and pulled in a state where the unit main body is placed on supporting members provided on both side plates of the housing. Along with that, the rolling member provided on the supported member of the unit body rolls on the supporting member, whereby the movement of the unit body is easily performed. Particularly in this means, the unit main body has left and right side wall portions, and at least one of the side wall portions of the both side wall portions is recessed to receive the supported member (rolling member) in the recessed portion. The department was set up. By the supported member being accommodated in the accommodating portion, the overhanging of the supported member from the unit main body in the vertical direction and the lateral direction can be suppressed. This makes it possible to reduce space restrictions in the housing while making it easy to attach and detach the display unit.

  For example, the capacity of the hopper device (storage tank) for storing medals using the space under the display unit generated by applying this means is expanded, or the pattern is used using the space on the side of the display unit It is possible to enlarge the display device (surrounding body) and improve the visibility in the game.

  The “wall portion” includes a plate-like one, one having irregularities such as ribs on the surface, and one having an opening such as a square hole penetrating inside and outside.

  Means 2. In the side wall portion of the unit main body, the housing portion is formed by being recessed inward to the inside of the unit main body to form the housing portion, and the supported member is attached to the bottom of the step portion facing the side plate of the housing in the housing portion. The gaming machine according to the means 1, characterized in that

  According to the means 2, the side wall portion of the unit main body is recessed in a step-like manner toward the inside of the unit main body to form the accommodation portion, and the supported member (rolling member) is attached to the step difference bottom portion of the accommodation portion. Compared with the case where the supported member (rolling member) is attached to the upper surface of the step-like housing portion (step top at the top of the step space), the space between the support member (rolling member) and the housing portion The space formed in the housing can be used to reduce the space restrictions in the vertical direction in the housing portion. For example, it is preferable to provide a floating suppressing plate (upper guide portion 350 of the support rail 300) extending on the housing side so as to be accommodated in the space from the side plate of the housing. Thus, when the unit body is lifted (slanted in the front-rear direction) from the support member of the unit body when mounted, the supported member (rolling member) hits the lift suppressing plate to suppress the lift. It is possible to expect further improvement of workability.

  Means 3. The gaming machine according to the means 2, wherein the unit body comprises a bottom wall portion (bottom plate portion 410b), and the step bottom portion of the step-like housing portion is connected to the bottom wall portion of the unit body.

  According to the means 3, the storage portion is connected to the side wall portion and the bottom wall portion of the unit main body. That is, the housing portion is formed at the lower corner of the unit body. Since the accommodating portion is at the lower corner of the unit body, spatial constraints in the vertical and horizontal directions of the display unit can be suitably reduced. For example, the size increase of the pattern display device and other components (main controller etc. ) Can be easily arranged.

  Further, for example, in the case where the housing portion is formed at the center in the height direction of the side wall portion, the housing portion has a space which is limited at the upper and lower sides. For this reason, in the state where the display unit is completely mounted, the support member may be vertically sandwiched between the housing portion and the supported member. In such a case, when mounting the display unit, the operator needs to insert the support member into the space sandwiched between the housing portion and the support member. In order to insert the support member into such a limited space, for example, the operator needs to visually mount the display unit while visually confirming the positional relationship between the housing portion, the supported member, and the support member. Yes, there is concern about the deterioration of workability. However, as described above, by setting the accommodating portion at the lower corner of the unit body, the lower side of the held member is opened. When the display unit is mounted, the supported member can be placed on the support member by lowering the display unit relative to the support member from the upper side of the support member. That is, when the display unit is mounted, it is not necessary to confirm the positional relationship between the support member and the housing portion. Therefore, it becomes possible to secure the workability when the display unit is attached.

  According to the means 4, the rolling member is provided above the bottom of the unit body. That is, the rolling member does not protrude downward from the bottom of the unit body. For example, even when the display unit is placed on the floor or the like when replacing the display unit, the rolling member does not project downward from the housing as described above, so the rolling member contacts the floor or the like There is nothing to do. For this reason, it is possible to prevent the inconvenience that the rolling member functions unintentionally and the display unit moves. Even if an unexpected external force is applied to the display unit from above, the display unit is not supported by the rolling members, and therefore no load is directly generated on the rolling members. Therefore, it is possible to suppress the occurrence of inconveniences such as deformation and to protect the function.

  Means 5. The game according to any one of the means 1 to 4, characterized in that a spacer member (spacer member 270) for attaching the support member in a state of being separated from the side plate of the case is provided on the side plate of the case Machine.

  According to the means 5, the spacer member is provided for attaching the support member away from the side plate. In a gaming machine such as a slot machine, a bracket for reinforcing the casing, a relay board, etc. may be provided on the side plate of the casing. Since it is possible to adjust the support position of the unit body with respect to the side plate of the housing by the spacer member, that is, to adjust the offset amount of the support member from the side plate of the housing, It can be configured to avoid interference with the display unit. Therefore, it becomes possible to control the attachment at the time of attachment or detachment of the unit main body, and to perform work easily.

  Further, by adjusting the offset amount not by the support member itself but by the spacer member, it is possible to change the support position by replacing only the spacer member. That is, since it is not necessary to newly install a support member according to a model change, effective use of resources can be achieved.

  Means 6. The gaming machine has a housing-side component (door support bracket 200) mounted inside the side plate of the housing, and an offset amount (offset amount W2, etc.) of the support member from the side plate set by the spacer member. The gaming machine according to the means 5, characterized in that W4) is made larger than the amount of overhang (protrusions W1, W3) of the component from the same side plate.

  According to the means 6, the component parts of the gaming machine inside the side plate of the case (metal fittings for reinforcing the case, a door support for supporting the front door covering the front of the case, a relay terminal board and an external terminal board Etc.), the spacer member is provided so that the offset amount of the support member from the same side plate is larger than the overhang amount of the component from the side plate, whereby the unit main body can be detached. The interference between the component parts and the unit body can be suppressed and the work can be easily performed. In particular, by configuring the overhang amount and the offset amount to be substantially the same, it is possible to maximize the size of the display unit in the left-right direction while taking into consideration the workability when attaching and detaching the display unit.

  Means 7. The component described in the means 6 is characterized in that it includes at least a door support (door support fitting 200) for rotatably supporting a front door (front door 12) for closing the opening of the housing. Of gaming machines.

  According to the means 7, the front door for closing the opening of the housing is rotatably supported by the door support provided on the side plate of the housing. The spacer member is provided such that the offset amount of the support member from the side plate is larger than the amount of protrusion of the door support from the side plate of the housing. As a result, there is no need for an auxiliary operation such as tilting and inserting the unit body at the time of attaching and detaching the unit body, and the operability can be improved.

  Means 8. The offset amount is set to be larger than a minimum projection amount of the front door which protrudes inward from the side plate in front of the opening of the housing in a state where the front door is opened. Of gaming machines.

  According to the means 8, the offset amount of the support member set by the spacer member is larger than the minimum projection amount of the front door which protrudes inward from the side plate of the housing in a state where the front door is opened. As a result, when the front door is opened so as to minimize the amount of projection, the unit body (display unit) can be attached and detached without interfering with the front door and the door support bracket. That is, since it is possible to attach and detach the unit main body in a state where the front door is opened without removing the front door, improvement in workability can be expected.

Means 9. A protrusion (protrusion 533) protruding toward the side plate of the housing and the protrusion are connected to the supported member, and the protrusion is connected to the support member or the spacer member. While providing a movable locking member (guide piece 530) having a movable portion (arm 532) elastically deformed by force,

  According to the means 9, when the display unit is attached, the projection of the movable locking member abuts against the support member or the spacer member by pushing the display unit to the back side of the housing, and the projection is deformed and restored by the movable portion. It will be in the state accommodated in the accommodation groove of a support member and a spacer member. On the other hand, when the display unit is detached, by pulling the display unit to the front of the gaming machine, the projection is caught by the stopper of the accommodation groove, and the movement of the display unit to the front of the gaming machine is restricted. That is, when removing the display unit, the display unit is temporarily stopped before it is detached from the housing. When the display unit is detached, movement of the display unit is temporarily stopped without visually confirming the position at which the display unit is detached from the support member. It can be reported that the withdrawal is near. As a result, it is not necessary for the operator to carry out the dismounting operation of the display unit while paying attention to the degree of engagement of the display unit and the support member, and the workability can be improved.

  Since the movable locking member protrudes laterally and is accommodated in the spacer member, a space (dead space) formed between the spacer member and the side plate of the housing can be utilized, and the space Effective use becomes possible.

  Further, since the movable locking member can be elastically deformed toward the side plate of the housing, even if there is a component such as a door support near the entrance of the housing, the component is elastically deformed by itself. It can be configured to be accommodated in the spacer member by avoiding the interference with and restoring it to the original shape.

  In addition, the "accommodating groove" also includes a through hole having no bottom, in addition to a recess having a bottom.

Thereby, when attaching or detaching the surface changing unit 400 mentioned later to the housing | casing 11, that the surface changing unit 400 interferes with the door support metal fitting 200 can be avoided.

  On the other hand, the right side plate 11 e of the housing 11 is provided with a hook receptacle 220 inside thereof. The amount W3 of protrusion of the wedge-receiving bracket 220 from the right side plate 11e is sufficiently smaller than the width of the support rail 300 (the width of the lower guide portion 320). That is, even in a state where the support rail 300 is attached to the right side plate 11 e, the lower guide portion 320 for supporting the surface changing unit 400 projects inward beyond the wedge receiving bracket 220 and supports the surface changing unit 400. The width of the lower guide portion 320 can be secured. Therefore, without using the spacer member, it is possible to avoid the interference of the resurfacing unit 400 with the hook receiving bracket 220 at the time of mounting and dismounting of the resurfacing unit 400. The protrusion amount W3 of the hook receiving bracket 220 corresponds to the improvement of the rigidity of the opening of the housing 11, the rigidity improvement of the hook receiving bracket 220 itself, and the fraudulent act performed from the boundary portion between the housing 11 and the front door 12. It tends to be bigger. As described above, in the case where the protrusion amount W3 is large and the attachment / detachment of the surface changing unit 400 is hindered, interference can be avoided by providing the spacer member in the right side plate 11e as well as the support unit 260 on the left side.

  As described above, since attachment and detachment of the surface changing unit 400 are not prevented by the brackets 200 and 220, there is no need to remove the brackets 200 and 220 each time the face changing unit 400 is attached. Can be efficiently removed. Further, although the offset of the support rail 300 is essential for the efficient attachment and detachment of the surface changing unit 400, if the offset amount W2 is unnecessarily increased, disadvantages such as an increase in dead space inside the housing 11 may occur. . 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 provided at the lower end of the base plate portion 310 in addition to a long plate-like base plate portion 310 extending in the front-rear direction parallel to the side plates 11d and 11e. A lower guide portion 320 is formed by bending vertically inward, and an upper guide portion 350 formed by bending vertically inward at the upper end of the base plate portion 310. Thus, the space in the left-right direction in the housing 11 can be effectively used by arranging the guide portions 320 and 350 in parallel, instead of arranging them laterally. Further, in the present embodiment, the guide portions 320 and 350 are formed by bending both ends of one plate material to the same side, thereby reducing the number of parts.

At the tip end of the arm 616 is formed a hook portion 617 which protrudes downward so as to be able to be locked with respect to the notch portion 352 of the support rail 300, and the lever is pressed by pressing the operation portion 615 toward the front side of the slot machine 10. The member 610 rotates on the basis of the central axis of the support shaft 613, and the collar portion 617 moves upward.

  An overhanging portion 618 projecting rearward is formed on the rear surface side of the operation portion 615, and the overhanging portion 618 is in contact with the inner wall of the lever communication hole 611. That is, the lever member 610 is rotatable in a range from the state in which the projecting portion 618 abuts on the inner wall of the lever communication hole 611 until the front end portion of the lever member 610 abuts on the lever communication hole 611 .

  On the rear side of the collar portion 617, a guide surface 619 inclined obliquely upward is formed, and by the guide surface 619, the collar portion 617 functions as the upper guide portion 350 of the support rail 300 when the inner case 410 is attached. (In detail, it is guided to notch 352). Further, at the rear end portion of the outer surface of the arm 616, a hook portion 620 which protrudes outward is formed. At the upper part of the hook portion 620, a guide surface 621 which slopes downward toward the outside is provided. At the front of the outer surface of the arm 616, a constricted portion 622 extending up and down is formed. When an external force is applied to the rear side of the arm 616, for example, the hook portion 620 from the side toward the inside, the arm 616 is configured to be bent inward with respect to the constricted portion 622.

  Next, a biasing member for biasing the lever member 610 in a predetermined rotational direction will be described. A leaf spring 631 as an urging member is provided on the rear side of the lever member 610. The plate spring 631 has an elongated shape extending horizontally, and is fixed to the right side plate portion 410 e by a fastener such as a screw. The front end of the plate spring 631 is in contact with the action portion (not shown) provided on the lever member 610 from the upper side. Thus, the lever member 610 is configured such that the hook portion 617 is always urged downward. In the present embodiment, the plate spring 631 is used as the biasing member. However, by using a coil spring instead of the plate spring 631, the collar portion 617 is always urged downward. Good. Further, although the locking means (the lever member 610 and the biasing member) is provided on both the left and right sides, the present invention is not limited to this, and it may be at least one side (for example, the opening / closing basic shaft side of the inner door 700).

  Attachment / detachment assisting mechanism including slide rail 510 and roller 540 provided on side plate portions 410 d and 410 e of inner case 410, and restricting means including guide piece 530 and locking means including lever member 610 Is configured not to project downward than the bottom plate portion 410 b of the inner case 410. That is, the outer surface of the bottom plate portion 410b of the inner case 410 is configured to be the lowermost portion. When the inner casing 410 (the surface changing unit 400) is placed on the floor or the like at the time of unit replacement, the outer surface (the mounting portion described above) of the bottom plate portion 410b abuts on the floor or the like. As a result, even when the inner casing 410 is carelessly placed on the floor or the like, the attachment / detachment assisting mechanism, the restricting means, and the locking means provided on the side plate portions 410d and 410e may be deformed or broken. A malfunction can be prevented, and it can also be prevented that the roller 540 rolls and the inner case 410 moves unexpectedly.

(Description of attachment / detachment work of inner case 410)
The mounting and demounting operation of the inner case 410 (the surface changing unit 400) will be described with reference to FIGS. FIG. 23 is a partial schematic view showing how the inner case 410 is assembled when the inner case 410 is viewed from the side, and FIG. 24 shows the state where the inner case 410 is completely attached to the case 11. FIG. 23 (a) shows the state where the roller 540 of the inner case 410 is placed on the support rail 300, and FIG. 23 (b) shows the movement state of the inner case 410 accompanied by the rotation of the roller 540. 23 (c) shows a state in which the inner case 410 has been attached to the support rail 300. When mounting the inner case 410, the operation 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 mounted on the housing 11 in a section where the inner housing 410 moves to the mounting completion position, the frictional resistance is generated between the inner housing 410 and the support rail 300 in contact therewith. And a high friction section which produces a frictional resistance greater than the frictional resistance which occurs 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, in the low friction section, the support rail 300 and the roller 540 are in point contact, and in the high friction section, the support rail 300 and the slide rail 510 are in surface contact. Thus, by providing the low friction section (point contact section L1) and the high friction section (surface contact section L2), the improvement of the attachment / detachment workability of the inner case 410 and the slot machine 10, particularly the inner case 410, etc. It is possible to protect and. The details will be described below.

  Here, "point contact" means that the contact site in the unit movement direction is point-like when the surface changing unit 400 (inner casing 410) moves. In addition, when using a rotating body such as a roller 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). Although contact may be linear, if the contact site in the unit movement direction is point-like, this is also included in “point contact”. Further, for example, when the rotating body contacts the plate surface, it is also assumed that the contact portion of the rotating body spreads due to the force such as weight, but even when the contact site of the rotating body spreads due to the force such as weight It shall be included in "point contact".

  When mounting the inner case 410 (surface changing unit 400) as shown in FIG. 23 (a), the roller 540 is placed on the horizontal portion 321 of the support rail 300, and the inner case 410 is lifted and the inside of the case 11 is raised. 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 low at the time of mounting, these front inclined portions 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 smooth mounting can be performed. Further, in a state where the roller 540 is placed on the upper surface of the horizontal portion 321 (hereinafter referred to as the contact surface 321a) beyond the resin piece 330, when the inner casing 410 unexpectedly rolls forward, the resin piece 330 is Since the roller 540 is hooked 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 case 410 is removed, the roller 540 comes into contact with the resin piece 330 by pulling the inner case 410 to the front side, and the roller 540 is located at the front end of the lower guide portion 320, that is, the inner case 410. It can be suggested to the worker that it is in a state just before leaving the housing 11.

  Next, as shown in FIG. 23B, in the state where the roller 540 is placed over the resin piece 330 and on the contact surface 321a, the supported portion 512 of the inner case 410 slides on the slide rail It is supported by the resin piece 330 with the surface 512 a in contact with the resin piece 330, and the roller 540 of the inner case 410 is supported by the horizontal portion 321. That is, since the inner case 410 is supported by the support unit 260 of the case 11 at a total of four points at two points on one side, the weight of the inner case 410 is quickly and stably stabilized on the case 11 side. You can deposit it. In addition, since it is supported at four points in this way (hereinafter, the state of being supported at four points is referred to as a point contact state), the inner case with respect to the contact surface 321a of the horizontal portion 321 of the support rail 300 of the case 11 is provided. The slide rail sliding surface 512a of the slide rail 510 of the body 410 is in a noncontact, so to speak, floating state. When the inner housing 410 is moved in the front-rear direction, the roller 540 rolls on the contact surface 321 a and the slide rail sliding surface 512 a slides while being in contact with the resin piece 330, thus providing appropriate frictional resistance. While the inner case 410 can be moved back and forth.

  The resin piece 330 has not only the function as the fall prevention means of the inner case 410 (the surface changing unit 400) described above but also the function as the resistance reduction means for reducing the frictional resistance when moving the inner case 410. Have. If attention is paid to this point, in the case where the protrusion is formed by bending the front end of the support rail 300 and used as a substitute for the resin piece 330, it is desirable to coat the protrusion with a fluorine resin or the like with small frictional resistance. .

  In the present embodiment, the amount of protrusion of the top portion 333 formed on the resin piece 330 from the support rail 300 is made equal to the amount of protrusion of the roller 540 from the slide rail sliding surface 512 a, 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 made larger than equal, the front portion of the slide rail sliding surface 512a is lifted so that the rear portion of the inner case 410 is inclined, so the inner case It becomes possible to carry out the movement to the back side of case 11 further easily with the self weight action of 410.

(Description of roller depression and friction reduction)
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 disengages from the lower guide portion 320. The unit-side pitch of the central 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 with respect to the housing-side pitch of the upper end of the rear inclined surface 332 and the upper end of the rear inclined portion 323 Almost the same. For this reason, the guide portion 513 is guided to the rearward inclined surface 332 of the resin piece 330 substantially in synchronization with the detachment of the roller 540. That is, the point contact state shown in FIG. 23B is shifted to the surface contact state where the slide rail sliding surface 512a and the contact surface 321a are in surface contact. L1 shown in FIG. 23 is a point contact section where the inner casing 410 is moved in a point contact state, and L2 is a surface contact section where the inner casing 410 is moved in a surface contact state. By the way, when the rear inclined portion 323 is not provided, the inner case 410 is suddenly dropped upon impact switching when L1 and L2 are switched, but according to the configuration of the present embodiment, the inner case 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 slippage caused by the resin piece 330 is not utilized, resulting in a greater frictional resistance than the point contact state. As a result, even when the inner casing 410 is vigorously pushed to the back side of the casing 11 in a point contact state in which there is little frictional resistance, the frictional resistance increases when it is shifted to the surface contact state. (C) to reach the mounting completion position shown in FIG. 23C (the position where the projection 441 of the inner case 410 abuts on the bent portion 251 of the partition plate 250). The momentum of the housing 410 can be reduced. By doing this, it is possible to suppress a defect such as breakage of the slot machine 10 or the like when the inner casing 410 vigorously collides with the back plate 11 c of the casing 11.

  Next, the removal operation of the inner case 410 will be described. When the inner case 410 is removed, the operation is performed in the order of FIG. 23 (c) → FIG. 23 (b) → FIG. 23 (a) in reverse to the mounting. By pulling the inner casing 410 to the front side from the mounting completed state shown in FIG. 23C, the roller 540 is lifted along the rear inclined portion 323 to the contact surface 321a, and the guide portion 513 is inclined rearward of the resin piece 330. It is lifted along the surface 332 to the top 333. At this time, since the roller 540 is guided by the rear inclined portion 323 and the guide portion 513 is also guided by the rear inclined surface 332, it can be pulled relatively easily. Then, by pulling closer to the front side, as described above, the roller 540 rides over the resin piece 330 and the detachment of the inner case 410 is completed (see FIG. 23A). The sliding contact of the inner casing 410 is improved by using a material with little frictional resistance on the contact surface of the support rail 300 and the slide rail 510 or by applying a coating with a fluorine resin with low frictional resistance to the contact surface. The inner housing 410 can be more easily pushed in or pulled out.

(Description of operation of the regulation means)
The operation of the restricting means for restricting the attaching / detaching direction of the inner case 410 when the inner case 410 is attached / detached will be described. When mounting the inner case 410 (surface changing unit 400) as shown in FIG. 23A, the roller 540 is placed on the contact surface 321a of the support rail 300, and the inner case 410 is lifted and the inside of the case 11 is raised. Push into. When the inner casing 410 is pushed as described above with respect to the casing 11 while being inclined forward and backward, the main rib 425 of the inner casing 410 abuts on the lower surface of the top plate 11a of the casing 11, The main rib 425 moves so as to slide on the lower surface of the plate 11a. Thereby, the inconvenience that the inner case 410 is obliquely inserted into the case 11 is restricted.

  Furthermore, as described above, the first box 480 of the housing 11 and the left and right guide ribs 470 are provided in proximity to each other. For this reason, when the inner case 410 is pushed into the case 11 by being inclined to the left and right, the first box 480 and the guide rib 470 abut against each other, so that the inclination thereof is on the lower side of the inner case 410. It can be suppressed. When the inner case 410 is further pushed to the back side of the case 11, the second box 490 and the guide rib 470 abut each other, so that the inner case 410 is inclined to the left and right by the inner case 410. Suppressed on the upper side of the By thus providing the restriction means (boxes 480 and 490 and the guide rib 470) at a low position at the front and at a high position at the rear, in the initial stage of installation, on the lower side with small deviation and at the time of installation completion. It becomes possible to regulate on the upper side which can suppress a gap effectively. Furthermore, by restricting at four places in this way, the rotation and twisting to the left and right of the inner casing 410 can be effectively suppressed, so that unexpected displacement after the completion of mounting can also be suppressed.

  That is, these ribs 425 and 470 not only have a function as a reinforcing portion for enhancing the rigidity of the respective plate portions 410a, 410d and 410e, but also have a shift regulating function at the time of mounting the surface changing unit 400 to the housing 11. There is.

  In addition, since the main rib 425 is provided with the inclined surface 427, when pushing in the inner case 410, the main rib 425 is not caught on the front end edge of the top plate 11a, and a problem that the pressing operation is not generated does not occur. Further, since the amount of protrusion of the sub rib 426 is suppressed smaller than that of the main rib 425, the sub rib 426 does not disturb the pressing operation. Similarly, since each guide rib 470 also has the inclined surface 471, when the inner casing 410 is pushed in, the guide rib 470 is not caught in the boxes 480 and 490, so that there is no problem that the pushing operation is hindered. Further, since the amount of protrusion of the auxiliary rib 472 is also smaller than that of the guide rib 470, the pushing operation is not hindered.

  Also, as shown in FIG. 23B, when the inner housing 410 reaches a predetermined position in a state where the inner housing 410 is supported by the support rail 300 at four points, the resin piece 520 of the slide rail 510 Are arranged close to the lower surface of the upper guide portion 350 of the support rail 300. That is, the amount by which the contact portion 521 formed on the resin piece 520 protrudes from the holding portion 515 is 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 of 320 and 350. Thereby, the inner case 410 can be rotated with reference to the resin piece 330, and the upper part of the inner case 410 can be restricted from rising upward. In the present embodiment, when the inner casing 410 is shifted to surface contact, the resin piece 520 is also separated from the upper guide portion 350 as the roller 540 is separated from the lower guide portion 320. Is configured to As a matter of course, it is possible to make the restriction in the vertical direction effective until the mounting is completed by forming an inclined portion and a stepped portion along the movement of the resin piece 520 at the rear of the upper guide portion 350.

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

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

  When the inner casing 410 is further moved to the back side and the projection 533 of the arm 532 reaches the guiding hole 312, the projection 533 is guided by the arm 532 being restored to its original shape by the elastic force. The hole 312 is fitted. Then, along with the further movement of the inner case 410 to the back side, the projection 533 also slides in the guide hole portion 312 to the back side. The guide hole 312 includes a front horizontal hole 313 provided on the front side, a rear horizontal hole 314 provided below and to the rear of the front horizontal hole 313, and an inclined hole 315 connecting them. The holes 313 to 315 are provided corresponding to the moving direction of the roller 540. That is, in the state where the protrusion 533 is present in the front horizontal hole portion 313, the roller 540 is on the horizontal portion 321, and in the state where the protrusion 533 is present in the inclined hole portion 315 (point contact state) The roller 540 is separated from the lower guide portion 320 in a state in which the protrusion 533 is on the inclined portion 323 and the projection 533 exists in the rear horizontal hole portion 314 (surface contact state). In addition, it is desirable that the slope of the inclined hole 315 be equal to the slope of the rear slope 323. By doing this, even when the roller 540 rolls 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 casing 410 is pushed in or pulled out, the projection 533 is moved in a state of being fitted into the guide hole portion 312 in accordance with the movement of the inner casing 410, whereby the directions of the pushing or pulling out are performed. The vertical direction is less likely to occur because the That is, there is no need for the operator to adjust the push-in or pull-out direction when attaching and detaching the inner case 410, and the complication of the work can be suitably suppressed. Furthermore, by providing the above-mentioned control means and guide means independently, a large shift can be controlled by the control means, and a small shift can be controlled by the guide means. It can guide to a predetermined position (attachment position) without doing.

  Further, as described above, the guide piece 530 also has a drop prevention function. The drop prevention function will be described in detail with reference to FIGS. 11 and 22. Referring to FIG. 11, at the front end portion of the guide hole portion 312 of the support rail 300, an inclined surface 318 which is inclined toward the right side plate 11d of the housing 11 (that is, in a direction away from the inner housing 410) (Only the lower inclined surface 318 is shown in the figure). As shown in FIG. 22, a hook 535 corresponding to the front end edge of the guide hole 312 is formed in the front of the projection 533 of the guide piece 530. The hooking portion 535 has a wall shape which is erected substantially at a right angle from the arm 532 to the outside of the inner casing 410, and can be locked to the front end edge of the guiding 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 accommodated in the guide hole portion 312 of the support rail 300, and the inner casing 410 is specified. The hook portion 535 of the guide piece 530 abuts on the front end edge of the guide hole portion 312 and the further movement of the inner casing 410 is restricted.

  As described above, the movement of the inner case 410 is restricted before the inner case 410 is completely pulled out from the case 11, and the withdrawal is temporarily restricted, so that the inner case 410 is accidentally dropped. Can be avoided. By restricting the movement of the inner case 410, it is possible to notify the operator that the inner case 410 can be detached, and the inner case 410 (more specifically, the roller 540) is supported by the support rail 300. The pull-out operation can be performed even if the operator does not visually check which position is located with respect to the contact surface 321a in detail.

  When the movement of the inner case 410 is restricted when the inner case 410 is pulled out, the protrusion of the guide piece 530 is first tilted by tilting the inner case 410 backward by a predetermined angle (about 10 ° in the present embodiment) or more. The protrusion 533 abuts on the inclined surface 318, and the protrusion 533 is moved upward along the inclined surface 318 while the arm 532 is bent to the inside of the housing 11, and the protrusion 533 is released from the guiding hole 312. Thereby, the movement restriction of the inner case 410 is released, and the inner case 410 can be pulled out further. As described above, the movement of the inner casing 410 is temporarily stopped as described above, even when it is not visually confirmed whether the inner casing 410 is placed on the support rail 300 when the inner casing 410 is removed. Thus, the worker can easily recognize that the inner housing 410 is approaching release. Therefore, when the inner casing 410 is detached, the transfer of the weight burden of the inner casing 410 to the worker in a state unintended by the operator is suppressed, and the inner casing 410 can be prevented from coming off.

(Description of operation of locking means)
The operation of the locking means will be described with reference to FIGS. 23 (c) and 25 again. When the inner casing 410 (the surface changing unit 400) is pushed to the back side of the casing 11 along the support rail 300, as described above, the point contact state is shifted to the surface contact state. After being shifted to the surface contact state, the flange portion 617 of the lever member 610 abuts on the front end of the upper guide portion 350 by continuing the pressing operation. Along with the pushing operation, the collar portion 617 is lifted upward along the guide surface 619 against the biasing force of the plate spring 631 and placed on the upper guide portion 350. Then, in synchronization with the positioning of the inner casing 410 in the front-rear direction, the collar portion 617 fits into the notch 352, and the collar portion 617 is locked to the front end edge of the notch 352. That is, the inner case 410 is in a state in which the forward movement is restricted.

  In a state where the collar portion 617 is locked to the notch 352, the operation portion 615 of the lever member 610 is turned forward against the biasing force of the plate spring 631 with respect to the central axis of the support shaft 613 as a reference. As the lever member 610 pivots, the hook portion 617 separates from the notch 352.

  Here, the guide surface 621 is formed such that the center thereof corresponds to the lower end of the rising portion 354 of the cut and raised portion 351. That is, by the rotation of the lever member 610, the center of the guide surface 621 of the arm 616 abuts on the lower end of the rising portion 354. By further turning the operation unit 615 forward, the hook 620 is guided by the guide surface 621 on the side surface of the rising portion 354. In other words, the arm 616 is lifted upward in a state of being biased toward the rising portion 354 by bending inward. When the hook portion 620 moves to the upper side of the upper end of the rising portion 354, the hook portion 620 is locked to the upper end edge of the rising portion 354 as the bending of the arm 616 restores to the original state. Ru. As a result, the hooking portion 620 is held by the rising portion 354 and the lever member 610 is maintained in the state in which the folding operation is performed (see FIG. 25). That is, after the tilting operation of the operation unit 615, there is no need to continuously hold the operation unit 615, and the complicated operation of pulling out the inner casing 410 while pressing the operation unit 615 is avoided. be able to. Further, after the lever member 610 is pulled down, the hook portion 620 slides on the rising portion 354 and is separated from the upper guide portion 350 by pulling the inner case 410 toward the front side.

  The state in which the inner case 410 is completely attached to the case 11 will be described with reference to FIG. 24 again.

  On the back side of the housing 11, the stopper piece 316 of the support rail 300 is inserted into the insertion portion 517 of the slide rail 510. In the surface contact state, as the inner case 410 is further pushed to the back side of the case 11, the stopper piece 316 is inserted into the insertion portion 517, and the above state is obtained. Thereby, when the rear part of the inner case 410 is moved up and down unexpectedly, the stopper piece 316 abuts on the insertion portion 517, whereby the movement is suppressed. On the other hand, on the front side of the housing 11, the projections 343 of the support rail 300 are engaged with the engagement holes 551 and 553 of the slide rail 510, and movement in the vertical and horizontal directions is restricted. By thus 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 11 a of the housing 11, an illegal substrate is installed between the inner housing 410 and the top plate 11 a of the housing 11. You can reduce the space that can be In addition, since the guide rib 470 and the boxes 480 and 490 are also arranged close to each other, it is possible to reduce the space where the illegal substrate can be installed between the inner case 410 and the side plates 11 d and 11 e of the case 11. . That is, it can be said that the ribs 425, 426, 470 and 472 and the boxes 480 and 490 constitute means for preventing the installation of the illegal substrate. It is natural to increase the number of ribs 425, 426, 470, 472 or to increase the number or size of the boxes 480, 490 in order to more effectively prevent the installation of the illegal base. It is possible.

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

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

  On the other hand, a long bearing fitting 745 formed by bending a metal plate is fixed to the right end portion of the base 710 of the inner door 700 by a fastener (not shown) such as a screw. Support fittings 746 and 747 provided with insertion holes into which shaft portions of the support shafts 741 and 742 are inserted are provided on the upper and lower sides of the bearing support 745 corresponding to the support shafts 741 and 742 of the door support bracket 740. It is done. Then, after arranging the support brackets 746 and 747 above the respective support shafts 741 and 742 and lowering the inner door 700, the shaft portions of the support shafts 741 and 742 are inserted into the insertion holes of the support brackets 746 and 747. It is assumed that the Thus, the inner door 700 is rotatably supported about an opening / closing axis extending in the vertical direction connecting both the support shafts 741 and 742 to the inner housing 410, and the front opening of the inner housing 410 is opened by the rotation. It is configured to be able to open and close the side.

  In the left side plate portion 410d of the inner case 410, a long-shaped wedge receiving bracket 750 is fixed along the opening inner peripheral edge of the case 11 by a fastener (not shown) such as a screw (see FIG. 18). . A pair of upper and lower wedge receiving portions 751 and 752 is provided in the wedge receiving bracket 750, and a guide piece 753 horizontally extending in the front-rear direction is bent and formed at the lower portion of the wedge receiving bracket 750.

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

  Further, at the lowermost portion of the interlocking rod 762, an operation piece 767 protruding downward of the inner door 700 is provided. More specifically, the operation piece 767 includes a bent portion 768 formed by bending the lower end portion of the interlocking rod 762 toward the bearing fitting 745 at a right angle. The interlocking rod 762 is moved downward by depressing the operation piece 767 (the bending portion 768). As described above, when the operation piece 767 is pushed down, the interlocking rod 762 moves downward because the biasing members such as coil springs are provided on the respective hooks 765, 766 so as to bias the retaining state. When the respective metal fittings 765, 766 are moved against the biasing force of the biasing member, the locked state between the metal fittings 765, 766 and the collar receiving parts 751, 752 is released, and the inner case The closed state of the inner door 700 with respect to the body 410 is released.

  When the operation piece 767 is formed by bending as described above, when performing an operation from the inner side of the opening / closing basic axis of the inner door 700 of the surface changing unit 400, the finger is hooked on the operation piece 767 (bent portion 768) Can be easily pushed down. If the operation from the outside of the surface changing unit 400 is performed, it is difficult to hook a finger or the like because the bending direction of the operation piece 767 is opposite, and the pressing is difficult. For this reason, in a state in which the surface changing unit 400 is completely attached to the housing 11, when a tool or the like is improperly inserted from the gap between the housing 11 and the front door 12 adjacent to the operation piece 767, It becomes operation, and pushing operation becomes difficult. Furthermore, when the tool intrudes as described above, the vertical portion of the operation piece 767 prevents access to the bending portion 768. In addition, since the entry direction of the unauthorized tool and the operation direction of the operation piece 767 are unlikely to be the same, the unauthorized operation becomes even more difficult.

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

In such a state, it is possible to visually recognize the back surface side of the main control device 770 (the surface opposite to the electronic component mounting surface of the main control substrate), and check whether various electronic components, electrical wiring, etc. are abnormal or incorrect. You can check.

  Incidentally, in the actual configuration of the slot machine 10, as shown in FIG. 6, FIG. There will be no trouble. Even if a device or mechanism projecting rearward of the slot machine is provided on the back surface of the inner door 700, the front space of the main control device 770 is opened with the opening of the inner door 700, and the rotation operation of the movable base plate 774 is also performed. There is no hindrance to In addition, even when the movable base plate 774 is rotated by about 90 degrees at the maximum, the left side plate portion 410d is provided with the upper opening 450 for avoiding interference with the main control device 770. There will be no trouble.

  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 the respective members. These sealing portions enable the case members 772 and 773 to be opened by being accompanied by destruction or the like, and after the opening, since the members subjected to destruction or the like remain as the opening history, confirmation of the opening fact is made by the opening history. It is possible. A plurality of rectangular seal seals S1 (two in the present embodiment) are attached to the case base 772 and the case cover 773 so as to straddle both of them. Once the seal seal S1 is pasted and peeled off, the adhesive peels off from the seal label and can not be pasted again, and if the seal seal S1 is peeled off, its evidence remains, so the case It can be checked whether the main control board has been removed from the member. With this configuration, if the case member is opened unfairly, etc., it is possible to find out the cheating by checking the sealing portion.

  On the other hand, in a state where the case member is mounted on the movable base plate 774, a rectangular sealing seal S2 is attached so as to straddle the movable base plate 774 and the case cover 773. The seal seal S2 is also a seal that peels off the adhesive from the seal label once it is attached and is peeled off, and can not be attached again, as in the case of the seal seal S1. Since it remains, it can be checked whether or not the case member has been removed from the movable base plate 774. Although not shown, the side plate 777 of the movable base plate 774 and the case member are provided with a plurality of sealing parts (so-called caulking parts) for connecting the both. It is possible to confirm whether or not the case member has been removed from the movable base plate 774 also by the destruction history of the sealing portion.

Similarly, the face change connectors 841 and 842 and the housing connectors 811 and 812 can be separated by the pulling operation of the inner housing 410. For this reason, 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, and 842 or pulling and releasing the connectors. Thereby, it becomes possible to efficiently carry out the replacement work of the surface changing unit 400.

  Further, as shown in FIG. 27, on the upper and lower surfaces inside the housing connector 811, guide inclined surfaces 860 are formed such that the distance between the upper and lower sides is narrowed as going from the insertion opening 811a of the connector 811 to the back side. A guide slope 861 is formed on the left side and the right side of the inside of the housing connector 811 so as to narrow the distance between the left and the right as it goes to the back side of the connector 811. In other words, the inside of the connector body 811b of the housing connector 811 is formed to be wider toward the insertion opening 811a, and the insertion opening 811a is larger than the insertion portion 841a of the surface changing connector 841. It is done. These guiding inclined surfaces 835 and 836, together with the guiding inclined surface 827, constitute connector guiding means for guiding the connection of the housing connector 811 to the facing connector 841. Similarly, the right side housing connector 812 has a guiding inclined surface (not shown), and the right support member 816 also has a guiding inclined surface (not shown).

  By providing the guiding inclined surfaces 827 and the guiding inclined surfaces 835 and 836 as the connector guiding means, the surface changing connectors 841 and 842 provided movably in accordance with the pushing operation of the surface changing unit 400 into the housing 11. Is adjusted in accordance with the housing connectors 811 and 812. More specifically, the insertion portions 841a and 842a of the surface changing connectors 841 and 842 abut the guiding inclined surface 827 by pushing the surface changing unit 400 into the housing 11 first. By being guided to the insertion openings 811a and 812a and further pushed in, the movement in the vertical and horizontal directions is promoted by the guide inclined surfaces 835 and 836, and is guided to a predetermined coupling position. Thereby, position adjustment of the surface changing connectors 841 and 842 with respect to the housing connectors 811 and 812 is completed. Therefore, in the replacement work of the surface changing unit 400, the worker does not have to adjust the inserting positions of the connectors 811, 812, 841, 842, so that the replacement work of the surface changing unit 400 can be performed more easily. It becomes possible. Furthermore, as described above, since the housing connectors 811 and 812 can be moved in any direction such as up and down and left and right in the coupled state, when replacing the surface changing unit 400, the force is different in the direction different from Even if it is added, it is possible to prevent the concentration of force on the connection points of the connectors 811, 812, 841, 842. Thereby, breakage of the connectors 811 812 841 842 can be avoided. Further, in the present embodiment, the surface changing connectors 811 and 812 are configured to be movable within the range of a predetermined gap, and the connectors are configured to be movable in a state regulated by a regulating member such as a spring. It does not mean that That is, the position adjustment is not performed by the deformation of the restricting member. For this reason, it is hard to produce a load in the part which regulates movement of a connector, and it can respond suitably also to repeated use.

  In the present embodiment, since the guiding inclined surface 827 of the support member 819 and the lower guiding inclined surface 860 are provided so as to be continuous, when connecting the housing connectors 811 and 812, It is possible to suppress the 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, by inserting the surface changing connectors 841 and 842 into the housing connectors 811 and 812, the surface changing connectors 841 and 842 and the housing connectors 811 and 812 are electrically connected, A control signal from 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 at the back of the housing, the force of pushing the same surface changing unit is weakened using frictional resistance, When the surface changing connectors 841 and 842 vigorously collide with the housing connectors 811 and 812, problems such as breakage of the connectors 811, 812, 841 and 842 can be suitably suppressed.

  Furthermore, in the mounting state of the surface changing unit 400 to the housing 11 (the connection state of the connectors 811, 812, 841, 842, the shape of the housing recess 442 is the same as that of the printed circuit 813, 814, the support members 819, 820 and Interference with the housing connectors 811 and 812 is avoided. By doing this, the back plate portion 410 c of the surface changing unit 400 and the back plate 11 c of the housing 11 can be disposed close to each other, and the depth inside the housing 11 can be effectively utilized. , 812, 841, 842 can be shielded from the clearance around it, it is possible to prevent the fraudulent act on the connection of the same connector 811, 812, 841, 842.

(Description of the completed state as the replacement unit 400)
The completed state of the surface changing unit 400 will be described again with reference to FIGS. 13 to 18. As the face changing unit 400, the reel device 650 is attached to the inside of the inner case 410, and the relay substrate 790 is attached to the upper side of the reel device 650 via the partition plate 791. Further, a main control device 770 is fixed to the back plate portion 410 c above the relay substrate 790, and an inner door 700 which also serves as liquid crystal display means is attached to the front surface of the inner case 410.

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

  In addition, a design plate (not shown) to which a design such as a character unique to the gaming machine is applied is attached to the shielding portion 721 of the front frame 720 provided on the inner door 700. The design plate is configured to be visible from the front of the gaming machine in a state in which the inner door 700 is closed to the inner housing 410. In addition, the shielding portion 721 is provided in front of the main control device 770, and it is possible to suppress such a disadvantage that the main control board 771 is directly viewed from the outside in front of the surface changing unit 400. That is, the inner door 700 is provided so as to close the opening of the inner casing 410 substantially in the entire area in a front view of the surface changing unit 400. It can be said that the inside door 700 constitutes a shielding means which shields the inside of the inside case 410 from the outside.

  As described above, in the surface changing unit 400, the inner door 700 is removably supported by the door support 740. Therefore, the inner door 700 can be easily removed from the inner housing 410 without using a special tool or the like. . As a result, by providing the display control device 730 on the inner casing 410 side, the inner door 700 can also be an object of reuse. That is, the reusability of the components of the slot machine 10 can be improved.

(Description of replacement work of the change unit 400)
Here, the replacement work of the surface replacement unit 400 at the time of model replacement in the gaming hall will be described. In this case, first, the locking of the front door 12 is released using a prescribed operation key K (see FIG. 3), and the front door 12 is opened at a predetermined angle or more. Next, by depressing the operation piece 767 provided at the lower left portion of the inner door 700, the hooked metal fittings 765 and 766 which lock the inner door 700 to the inner housing 410 are 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 portion 615 of the lever member 610 provided in the surface changing unit 400 to the front side. , Close the inner door 700 only. Then, the surface changing unit 400 is pulled toward the near side along the support rail 300, and when the inner case 410 is caught (once stopped), the front side is raised by about 10 °. When the resin piece 330 is brought into contact with the resin piece 330 just before it is pulled out, the unit 100 is pulled away further to release the reprocessing unit 400.

  After that, the new surface changing unit 400 is attached in substantially the same operation procedure as that at the time of detachment. That is, the new surface changing unit 400 is pushed to the back side of the housing 11 so as to be along the support rail 300, and when the new surface changing unit 400 abuts on the bending portion 251, the pressing of the surface changing unit 400 is finished. Thereafter, the slot machine 10 is locked by closing the front door 12, and the replacement of the unit is completed. The lower plate 80 is also replaced when replacing the model.

  At the time of replacement work, connectors 811, 812, 841, 842 for electrical wiring that connect the surface changing unit 400 and various other members (power supply box 100, hopper device 110, etc.) are pushed by the pressing operation of the same surface changing unit 400. Since the connection is released and the connection is released by the pulling operation, the connection and release operations of the connectors 811 812 841 842 may not be separately performed.

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

  As shown in FIG. 29 (a schematic view showing the installation state of the surface changing unit on the side of the slot machine), the inner case 410 of the surface changing unit 400 has the front of the inner case 410 as the opening of the case 11. It is mounted to project more forward than it is. That is, the boundary B1 between the inner casing 410 and the inner door 700 is offset in the depth direction with respect to the boundary B2 between the front door 12 and the casing 11. Specifically, a boundary B1 between the inner housing 410 and the inner door 700 is disposed in front of a boundary B2 between the front door 12 and the housing 11. The wedge receptacles 221 and 222 of the wedge receptacle 220 are provided on the rear side of the boundaries B1 and B2. In other words, the bowl receiving portions 221 and 222 are provided at positions sandwiched between the right side plate 11 e of the housing 11 and the right side plate portion 410 e of the inner case 410. As described above, since the bowl receiving portions 221 and 222 are provided at the rear of the gap and at a position sandwiched between the right side plate 11 e and the right side plate portion 410 e, the opening edge portion of the housing 11 and the front door 12 It becomes difficult to open the front door 12 by infiltrating a wire, a film or the like from a gap (boundary B2) of a portion where the outer peripheral rear end is opposed to the rear end. Therefore, it is possible to suppress fraud.

  The back plate portion 410c is generally planar as seen in FIG. 24 (schematic view), and the back plate portion 410c is mounted on the back plate 11c in a state where the surface changing unit 400 is mounted in the housing 11. It is formed to be substantially parallel to each other, and the depth region of the housing 11 can be utilized to the maximum extent. Referring to FIGS. 9 and 15, the side plates 410d and 410e and the housing 11 are also formed substantially parallel to the inner peripheral surface (side plates 11d and 11e) of the housing 11. By doing this, the region in the left and right direction of the housing 11 can be effectively used.

  Further, the housing recess 452 of the inner case 410 is formed in such a size that the front door 12 and the inner case 410 do not interfere with each other when the surface 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 removing it, it is configured not to interfere. In this way, the operator can perform the pressing operation and the pulling operation straight in the mounting direction without worrying about interference with the front door 12 with the front door 12 mounted. Therefore, the workability can be improved.

  As shown in FIG. 5, in the present embodiment, the open / close base axes of the front door 12 provided in the case 11 and the inner door 700 provided in the inner case 410 are provided on opposite sides in the left and right direction. It was composition. For this reason, in order to open the inner door 700 and access the main control device 770 mounted inside the inner casing, it is necessary to open the front door 12 by a predetermined angle or more. That is, since it is necessary to open the front door 12 widely in order to perform unauthorized access to the main control device 770, it becomes difficult to make a blind spot from the staff of the game arcade and the surveillance camera, and it is possible to prevent fraud. . Moreover, even if it is performed, since it is easy to be caught by the staff of the game arcade or the monitoring camera, it is possible to easily find an illegal act.

  Furthermore, since the operation piece 767 for opening the inner door 700 is provided on the opening / closing base shaft side of the front door 12, the front door 12 needs to be opened at a predetermined angle or more to operate the operation piece 767 (see FIG. 4). That is, it becomes difficult to open the front door 12 a little and release the locked state of the inner door 700. For this reason, in the state which opened both doors 12 and 700 a little, it can suppress accessing the main control apparatus 770 from the clearance gap.

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

  As shown in FIG. 4, the configuration provided with hook receiving portions 221 and 222 for closing front door 12 in a space sandwiched between side plates 11 d and 11 e of housing 11 and side plates 410 d and 410 e of surface changing unit 400. And That is, the bowl receiving portions 221 and 222 are disposed in the area sandwiched between the surface and the surface. Thereby, even if it is going to remove a bag using a wire, cellophane, etc., the movement tolerance | permissible_range can be regulated and the unauthorized opening of the front door 12 can be suppressed.

  As shown in FIG. 6, in the lever member 610 for performing the locking release operation of the surface changing unit 400, the operation portion 615 communicates with the inside and the outside of the surface changing unit 400. The exposed portion of the operation unit 615, which can be operated from the outside of the surface changing unit 400, is in a space sandwiched by the side plates 11d and 11e of the housing 11 and the side plate portions 410d and 410e of the surface changing unit 400. For this reason, it is difficult and time-consuming to put a finger or a wire into the above space for the purpose of cessation of fraud and it takes time, so it is easy to be caught by staff in the game arcade or a surveillance camera, and discover fraud easily It is possible to On the other hand, since the operation from the outside is also possible as described above, even when it is difficult to open the inner door 700 due to the failure of the closing mechanism of the inner door 700, the locked state of the surface changing unit 400 is external It becomes possible to release from the same and to remove the copying unit 400. In the present embodiment, the lever member 610 is configured to be operable from the inside and the outside of the surface changing unit 400. However, by completely separating the operation portion 615 from the outside of the surface changing unit 400, fraud is more suitably made unauthorized. It is good also as composition which can control operation.

  The casing 11 and the surface changing unit 400 are provided with a plurality of sealing portions (so-called caulking portions) as sealing means for connecting the two. In detail, a unit-side round hole 413 provided in the surface changing unit 400 (specifically, the reinforcing plate 411) and a case-side round hole (not shown) provided in the housing 11 are separated by a caulking band (not shown) It is connected in the impossible state. These sealing portions (bands for caulking) make it possible to remove the modification unit 400 by breaking or the like, and after removal, the members subjected to the breaking or the like remain as an opening history, so the opening history thereof It is possible to confirm the opening fact by. With this configuration, it is possible to detect a fraudulent act by checking the sealing unit, for example, if the surface changing unit 400 has been removed illegally.

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

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

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

  The inserted medal detection sensor 925 is actually composed of a plurality of sensors. That is, the storage passage 32 from the medal insertion device 30 to the hopper device 110 is configured such that medals can pass in one row. Then, the first passage is provided in the storage passage 32, and the second sensor and the third sensor are in proximity to the downstream side further away than the width of the medal (the extent to which the same medal is simultaneously detected in at least one time) And the inserted medal detection sensor 925 is configured by these first to third sensors. The main control device 770 monitors the time from the first sensor to the second sensor, and when the elapsed time exceeds a predetermined time, it is regarded as a medal clogging or an error and is regarded as an error. If an error occurs, the error notification is performed 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 turned off, only the second sensor is turned on, and both the second and third sensors are turned on. It is determined that the medals are taken in normally only when the third sensor is on and the second and third sensors are both off in this order, and the time to shift to each on / off switching is within a predetermined time. Otherwise, it is an error. The reason for this is to prevent frauds that cause medals to reciprocate in the vicinity of the insertion medal detection sensor 925 and misidentify that the medals are inserted, in addition to the medal clogging in the storage passage 32.

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

  The power failure monitoring circuit 902b monitors the power-off state, and generates a power failure signal at the time of power-off by the power switch provided in the power-supply box as well as at the time of power-off. Therefore, the power failure monitoring circuit 902b monitors the stabilized drive voltage of DC 12 volts in this example output from the power supply unit 902a, and determines that the power is shut off when the drive voltage drops to, for example, less than 10 volts. And a power failure signal is output. A power failure signal is supplied to each of the CPU 901 and the input / output port 904, and the CPU 901 executes power failure processing by recognizing the power failure signal.

  Even when the output voltage drops below 22 volts, the power supply unit 902a outputs a stabilized voltage of 5 volts which is used as a drive voltage in a control system such as the main controller 770 As the time during which the stabilization voltage is output, a time sufficient for the main control device 770 to execute power failure processing is secured.

  On the output side of the main control device 770, a medal passage switching solenoid provided in the selector 31, such as stepping motors for rotating the respective reels 655 to 657, a hopper device 110, a display control device 730, a hole management device not shown , And the like are connected via an input / output port 904.

  The display control device 730 is a control device for driving various lamps such as the central lamp portion 26, various speakers provided behind the speaker portions 82 and 83, and the liquid crystal display device 711. It has a substrate in 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. Therefore, the display control device 730 is a sub-substrate that performs auxiliary control in relation to the main control device 770, which is a main substrate that centrally manages the game. That is, the load on the main board is reduced by providing the sub board for the sound, the lamp, and the display regarding the indirect game.

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

  The RAM 953 is configured to be able to receive data (backup) supplied with a backup voltage from the power supply device 902 even after the power supply of the slot machine 10 is shut off, and the RAM 953 temporarily stores various data and the like. A backup area is provided in addition to the memory and area for storing.

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

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

  While providing the rail unit 500 which has the roller 540 in the inner case 410 which comprises the surface changing unit 400, the support rail 300 was provided in each side plate 11d and 11e of the case 11 (refer FIG.9 and FIG.13 grade | etc.,). At the time of attachment or detachment of the surface changing unit 400, the roller 540 rolls on the support rail 300 (specifically, the contact surface 321a) by pushing and pulling with the surface change unit 400 placed on the support rail 300. Do. For this reason, frictional resistance can be suppressed and work can be performed easily.

  In addition to providing a pair of left and right slide rails 510 on the side of the surface changing unit 400, a resin piece 330 is provided on each of the support rails 300 on the side of the housing 11, and the roller 540 and the supporting rail 300 are attached when attaching or removing the surface changing unit 400. And the resin piece 330 is in contact with the slide rail 510 (more specifically, the sliding surface 512a). Since the surface changing unit 400 is moved in a state of being supported by a total of four points of two points on one side, the stability at the time of attachment and detachment is improved. In addition, the contact between the slide rail 510 and the resin piece 330 can provide appropriate frictional resistance, thereby suppressing the inconvenience that the surface changing unit 400 moves despite the fact that the operator does not apply an external force. it can.

  In the configuration in which the roller unit 500 is provided with the roller 540 as a rolling member, the frictional resistance at the time of attachment of the surface changing unit is reduced, and the attachment / detachment workability of the surface changing unit 400 is improved. I tend to. In this respect, since the rail unit 500 is configured to be accommodated in the accommodation recess 452 of the inner casing 410, the space restriction in the vertical and horizontal directions by the rail unit 500 can be reduced. In the present embodiment, in particular, the roller 540 and the slide rail 510 are provided so as not to protrude below the bottom plate portion 410b of the inner casing 410 (see FIG. 15 and the like). When the surface changing unit 400 is placed on a floor or the like, the bottom plate portion 410b functions as a placement portion, and the roller 540 and the slide rail 510 do not contact the floor or the like, so that the roller 540 and the slide rail 510 can be protected. In addition, since the roller 540 does not contact the floor or the like, unexpected movement of the surface changing unit 400 can be suppressed.

  The support rail 300 is configured to have the lower guide portion 320 and the upper guide portion 350, and the two guide portions 320 and 350 stabilize the track when the surface changing unit 400 is mounted. By making the support rail 300 substantially U-shaped (in a front view of the slot machine 10) sandwiching the roller 540 in the upper and lower sides, the upsizing of the surface changing unit 400 is suitably suppressed, and the enlargement of the support rail 300 is avoided doing. By miniaturizing the support rail 300, it is possible to reduce the space restriction in the housing 11 by the support rail 300.

  As shown in FIG. 8 and the like, the support rails 300 were attached in a state of being offset from the side plates 11 d and 11 e of the housing 11 by the spacer members 270. By setting the offset amount to be larger than the amount by which the door support fitting 200 provided around the opening of the housing 11 and the inward protrusion from the side plates 11 d and 11 e of the wedge support fitting 220 is provided, each of the surface changing units 400 can be removed. Interference with the metal fittings 200 and 220 can be suppressed (see FIG. 12). That is, there is no need to remove each metal fitting when attaching and detaching the surface changing unit 400, and the workability can be improved.

  Furthermore, by making the offset amount substantially the same as (slightly larger than) the overhang amount, the dead space in the left and right direction inside the casing can be reduced, for example, fraudulently performed between the casing 11 and the surface changing unit 400 It is possible to suppress fraudulent acts such as installation of a substrate or the like.

  When the front door 12 is opened relative to the housing 11, the door components such as speakers and lamps attached to the back side of the front door 12 or the overhanging portion 15 of the front door is located in front of the opening of the housing. It may protrude to the inside of the left side plate 11d. At the time of attachment and detachment of the surface changing unit 400, there is a possibility that the projecting portion may interfere with the surface changing unit 400. On the other hand, in the present embodiment, the offset amount of the support rail 300 (specifically, the contact surface 321a) set by the spacer member 270 is larger than the inward protrusion amount of the front door. The replacement unit 400 can be attached and detached. That is, since the surface changing unit 400 can be attached and detached without removing the front door 12, improvement of workability can be expected.

  A part of the guide piece 530 provided on the side of the surface changing unit 400 is accommodated in the long hole 272 formed in the spacer member 270, and is movable in the long hole 272. For this reason, the dead space formed by the offset setting by the spacer member 270 can be effectively used. In addition, when the surface changing unit 400 is attached and detached, the movement of the surface changing unit 400 is guided by the guide piece 530, so that the trajectory of the surface changing unit 400 can be stabilized.

  As shown in FIG. 8 or FIG. 24, the boxes 480 and 490 provided on the side plates 11 d and 11 e of the housing 11 contact the side plates 410 d and 410 e (specifically, the guide ribs 470) of the surface changing unit 400 to change the surface. The configuration is such that movement of the unit 400 in the lateral direction is restricted. As a result, when pushing and pulling out the surface changing unit 400, it is not necessary for the operator to perform work while checking and correcting positional deviation in the left-right direction. This makes it possible to suppress the complication of work and to improve the workability.

  Boxes 480 and 490 are provided spaced apart longitudinally and vertically, and the front box 480 is configured to be lower and the rear box 490 is positioned to be upper. Thereby, when mounting the surface changing unit 400, first, restriction is performed in the lower portion (box 480) of the surface changing unit 400 having a relatively small deviation due to the inclination. In a state where the inclination is restricted to some extent by the box 480, the restriction is performed in the upper part (box 490) of the modification unit 400 that can restrict the inclination more suitably. As a result, it is possible to suppress the hooking of the surface changing unit 400 to the boxes 480 and 490 themselves, and it is expected to improve the mounting workability and the stability of the surface changing unit 400 in the mounting completed state.

  In the conventional configuration, the surface changing unit 400 is often supported and guided by a support member provided below the surface changing unit 400. On the other hand, the support and the guide were performed by the support rail 300 provided on the side of the surface changing unit 400. For this reason, it becomes possible to perform the support and guidance at a height closer to the center of gravity of the surface changing unit 400, and the stability of the surface changing unit 400 can be increased.

  In addition, there are two states, a point contact state in which the frictional resistance generated by the movement of the surface changing unit 400 is relatively low and a surface contact state in which the frictional resistance is relatively high, the surface changing unit 400 in the point contact state. Is easily moved, and in the surface contact state, the frictional resistance prevents the movement of the surface changing unit 400. Therefore, even when the surface changing unit 400 is vigorously pushed in a point contact state, the same surface changing unit 400 can be braked in a surface contact state, and collision with the housing side while maintaining the momentum is suppressed. it can. As described above, damage to the slot machine 10 when the surface changing unit 400 is attached can be suppressed.

  As described above, since braking is performed in addition to the support and guidance at a position close to the center of gravity of the surface changing unit 400, stable braking is performed while suitably suppressing the balance of the surface changing unit 400 from being broken by braking. be able to.

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

  (A) In the above embodiment, as shown in FIGS. 6 and 18, the left side plate portion 410d of the inner case 410 is configured to have the housing recess 452 as the "housing portion" at the lower end portion thereof. It is possible to change and to provide an accommodation part in the central part of the up-and-down direction of left side board part 410d. In this case, since the surface changing unit 400 is supported and moved at a height closer to the center of gravity of the surface changing unit 400, its stability can be improved. Further, braking of the surface changing unit 400 is performed using the frictional resistance generated between the support rail 300 on the housing 11 side and the slide rail 510 on the surface changing unit 400 side. As described above, by bringing the generation position of the frictional resistance close to the center of gravity, the disadvantage that the balance of the surface changing unit 400 is broken due to the frictional resistance is suitably suppressed. Further, by forming the housing portion in the form of a groove extending in the front-rear direction, the downward exposure of the slide rail 510 and the roller 540 attached thereto can be reduced. Thereby, those slide rails 510 etc. can be protected more suitably.

  In this case, it is not necessary to unify the support positions (heights) on the left and right of the surface changing unit 400, but in consideration of workability and stability at the time of mounting, the same height is obtained on the left and right. It is desirable to configure

  (B) Referring again to FIGS. 6 and 18, in the above embodiment, the support rails 300 are provided on the side plates 11d and 11e of the housing 11 at portions facing the reel device 650. This may be changed as follows. That is, the support rail 300 may be provided on the upper side of the side plates 11 d and 11 e above the portion facing the reel device 650. More specifically, the support rail 300 provided substantially at the center in the vertical direction in the left side plate 11 d of the housing 11 is changed to be provided on the upper side of the left side plate 11 d. It is preferable to change the accommodation recess 452 provided in the left side plate portion 410d from the lower end portion to the upper end portion of the left side plate portion 410d. The size and arrangement height of the reel device 650 are often set in consideration of the player's visibility, and in particular, at the arrangement height, as shown in FIG. In many cases, the direction is set approximately at the center. As described above, by changing the formation position of the housing portion from the side of the reel device 650 to the upper side of the reel device, it is possible to reduce the spatial restriction in the left-right direction with respect to the reel device. Also in this case, the support positions (heights) on the left and right of the surface changing unit 400 do not necessarily have to be the same, but in consideration of workability and stability at the time of mounting, the same height on the left and right It is desirable to be configured to

  (C) In the above embodiment, the roller 540 and the slide rail 510 are not projected from the bottom of the inner case 410, but at least one may be projected. However, in this case, it is conceivable that, for example, the roller 540 and the slide rail 510 may come in contact with the floor by placing the surface changing unit 400 on the floor or the like at the time of replacement. Therefore, in consideration of the maintenance of the functions of the roller 540 and the slide rail 510 (such as assistance in mounting the facing unit 400), a protective cover or the like is provided so that the roller 540 and the slide rail 510 do not directly touch the floor or the like. Is preferred.

  (D) In the above embodiment, the spacer member 270 is formed by bending a plate material, and the spacer member 270 is used to adjust the offset from the side plate of the housing. This may be changed as follows. That is, using a plate-like spacer having a predetermined thickness, offset adjustment may be performed depending on the thickness. Moreover, it is also possible to perform offset adjustment by the length of the leg using the leg-like spacer which has a leg which stands up from a side plate. In addition, as a material of these spacer members, it is not limited to metal materials, such as aluminum, You may use synthetic resins, such as ABS resin.

  (E) In the above embodiment, although the offset amounts by the left and right spacer members are different, the left and right offset amounts may be the same by changing the offset amounts. This makes it possible to share the spacer members on the left and right and reduce the number of parts.

  Also, instead of providing the spacer members on both the left and right sides, the spacer members may be provided on either the left or the right side. For example, the spacer member may be provided only on the opening / closing base end shaft side of the front door.

  (F) In the above embodiment, the spacer member 270 is fixed to the partition plate 250 by welding, but this may be changed and fixed by a fixing tool such as a screw. Thus, replacement of the spacer member 270 is facilitated, and position adjustment (adjustment of the offset amount from the side plates 11 d and 11 e) of the support rail 300 is possible only by changing the spacer member 270.

  (G) In the above embodiment, the spacer member 270 is attached to the inner wall surface of the housing 11 to adjust the offset amount of the support rail 300 from the side plates 11 d and 11 e. Instead of this, it is also possible to adjust the offset amount by changing the size and shape of the support rail 300. Thereby, the number of parts can be reduced.

  (H) In the above embodiment, the partition plate 250 is provided at the center of the case 11 for the purpose of reinforcing the case 11 (see FIG. 8), but this may be changed so that the partition plate 250 is not provided. It is possible. In this case, for example, by extending the hopper device 110 upward, the capacity of the hopper device can be further expanded. However, when the partition plate 250 is not provided, it is desirable to take measures such as changing the material of the housing 11 from wood to a light metal such as aluminum in order to improve the strength of the housing 11.

  (I) In the above embodiment, as shown in FIG. 8 and FIG. 24 etc., box-like boxes 480 and 490 are provided on the side plates 11 d and 11 e of the housing 11 as “regulating members”. It is not limited to the shape. That is, it is sufficient to have a contact surface (inner surface of the side plates 485 and 495) capable of contacting the guide rib 470 formed on the inner casing 410 on the side of the face changing unit 400. For example, a cylindrical member whose outer shape has a cylindrical shape or a prismatic member whose outer shape has a prismatic shape may be provided. The portions of the cylindrical member and the prismatic member facing the side plates 410d and 410e of the inner casing 410 have contact surfaces that can contact the guide ribs 470 formed on the side plates 410d and 410e. The movement of the inner case 410 in the lateral direction can be restricted.

  The number of boxes 480 and 490 and the size in the front-rear and top-bottom directions (excluding the thickness direction on the left and right) are arbitrary. For example, by increasing the number of boxes 480 and 490, it is possible to reduce the 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). It is possible to more preferably suppress the fraud such as a fraudulent substrate or the like being installed in the dead space.

  Moreover, it is also possible to set it as the structure which does not provide the guide rib 470. FIG. However, in this case, by forming the inclined surface 471 in the guide rib 470, the hooking to the box 480, 490 is suppressed, and as a substitute for this, the side plate of the box 480, 490 has a curved shape inward. It is desirable to configure it to Thereby, the workability at the time of unit attachment and detachment can be secured.

  (J) In the above embodiment, as shown in FIG. 21, one roller 540 is provided on each of the left and right sides of the surface changing unit 400, but a plurality of rollers may be provided on each of the left and right sides. When a plurality of rollers are provided, it is also possible to provide a belt by bridging them. By rolling in a state in which the belt is in contact with the support rail 300 (specifically, the contact surface 321a) on the housing 11 side, the frictional resistance can be reduced, and the work can be performed smoothly. It is also possible to provide a plurality of teeth on the outer periphery of the roller and a recess corresponding to the teeth on the inner periphery of the belt so that the two mesh with each other as the belt rolls. The belt may be formed of, for example, a synthetic resin material such as synthetic rubber.

  (K) In the above embodiment, as shown in FIG. 13 etc., in addition to the roller 540, the slide rail 510 is provided with the resin piece 520, the guide piece 530, the bending member 550, etc. Although the workability at the time of attaching and detaching to the body 11 and the stability at the time of wearing are improved, the resin piece 520, the guide piece 530 and the bending member 550 may not be provided.

  (L) In the above embodiment, the liquid crystal display device 711 and the display control device 730 are provided on the inner door 700 on the side of the surface changing unit 400, but the liquid crystal display device 711 and the display control device 730 are changed. A display device 711 and a display control device 730 may be provided. However, when configured in this way, it is conceivable that the liquid crystal display device 711 and the display control device 730 do not fit inside the front door 12, and that the liquid crystal display device 711 and the display control device 730 protrude from the back side of the front door 12 to the housing 11 side. In the case where the portion thus overhanging interferes with the flatbed unit 400 when attaching or detaching the flatbed unit 400, the spacer member 270 adjusts the position of the support rail 300 from the inside to secure the workability. It is desirable to be able to

  (M) A shock absorbing member (a urethane pad, a silicon pad, a coil spring, etc.) is provided on the surface where the back plate 11c of the case 11 and the back plate portion 410c of the inner case 410 face each other. You may set as "." Thereby, the force of the surface changing unit 400 is first reduced in surface contact, and then the inner housing 410 collides with the buffer member to absorb the remaining force of the surface changing unit 400, which is more preferable. Damage to the slot machine can be suppressed. More preferably, the interference member may be provided at the same height as the center of gravity of the display unit 400 in a state where the inner case 410 is attached to the case 11. Thereby, the damping | braking by a buffer member can be performed stably.

  (N) In the above embodiment, the three reels 655 to 657 constituting the reel device 650 are individually removable, but the three reels 655 to 657 may be integrated into a subassembly.

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

  (P) In the above embodiment, as shown in FIG. 6, the main controller 770 is provided on the back side of the inner case 410, but this may be changed as follows. For example, the main control device 770 may be provided between the reel device 650 (specifically, the case member 651) and the side plate portions 410d and 410e of the inner casing 410.

  More specifically, the left side plate portion 410d and the reel device 650 (more specifically, the case member 651) are provided on the upper side of the accommodation recess 452 as the "housing portion" provided in the left side plate portion 410d of the inner case 410. The main controller 770 is provided in the space formed between the two. However, in this case, it is desirable to mount the main control device 770 in a state where it can slide in the front-rear direction of the slot machine 10. Thereby, the main control device 770 (particularly the main control board 771) can be easily visually recognized at the time of maintenance or the like. Even if the main control device is tampered with, the detection can be made easy.

  (Q) In the above embodiment, the support rail 300 (specifically, the lower guide 320) and the slide rail 510 (specifically, the roller 540) are in point contact with each other 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 in surface contact with each other, but this is changed as follows.

  For example, while the support rail 300 and the slide rail 510 are held in surface contact with each other in both the low friction section and the high friction section, the support rail 300 and the slide rail in such a configuration particularly in the low friction section. The surface roughness of at least one of 510 is made relatively small, and the surface roughness of at least one of the support rail 300 and the slide rail 510 is made relatively large in the high friction section. That is, by reducing the surface roughness of the portion in contact with each other in the low friction section and increasing the surface roughness of the portion in contact with each other in the high friction section, the optimum frictional resistance considering the work load and the braking force is provided. can do. In addition, it is preferable that a difference is given to the surface roughness by surface processing or surface treatment of the support rail 300 and the slide rail 510.

  (R) In the above embodiment, in the portion where the support rail 300 of the housing 11 and the slide rail 510 of the surface changing unit 400 are in contact, a portion with low friction and a portion with high friction are provided. This may be changed as follows. That is, the casing 11 is provided with another casing side contact member (member other than the support rail 300) in contact with the surface changing unit 400 (for example, the inner casing 410), and the casing side contact member and the surface changing unit 400 are configured. It is good also as composition provided with the part which becomes low friction, and the part which becomes high friction in the part which contacts the inner case 410 which performs.

  For example, a housing side contact member is provided on the inner surface of at least one of the side plates 11d and 11e of the housing 11 and the top plate 11a so as to extend back and forth and contact the inner housing 410. It is preferable to set two high and low friction sections (areas) that generate different frictional resistances with the body 410. In this case, surface treatment such as coating is applied to the mutually contacting portions of the inner casing 410 (more specifically, the respective plate portions 410a, 410d, and 410e) and the casing side contact member, thereby providing high and low friction sections having different frictional resistances. It can be easily realized.

  (S) 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 case 410 side of the surface changing unit 400. Since the display control device 730 is unique to each model and needs to be replaced according to the model change, the liquid crystal display device 711 may be used regardless of the model change, so the replacement is not always necessary. . The liquid crystal display 711 is provided on the inner door 700 provided detachably with respect to the inner casing 410, and the display control device 730 is provided on the inner casing 410 which is an object of model change. Thus, the liquid crystal display device 711 can be reused together with the inner door 700.

  (T) In the above embodiment, a donut-shaped liquid crystal display substrate 711 having substantially the same size as the front surface of the inner door 700 is provided as the “auxiliary display device”, but this is changed. 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 disposed above, below, or to the left or right of the reel device 650. Further, as the auxiliary display device, for example, a configuration in which a dot matrix display or the like other than the liquid crystal display device is mounted, or a configuration in which the auxiliary display device is not mounted may be employed.

  (U) The front door 12 provided in the housing 11 so as to be openable and closable may be configured by an upper door and a lower door which are divided into two in the vertical direction. In this case, the opening of the housing 11 is closed by upper and lower doors divided in the vertical direction, and the upper and lower doors are attached to the housing 11 in an openable / closable manner. Further, the upper door may be attached to the inner case 410 and the lower door may be attached to the case 11 so as to be openable and closable.
