The top plate member 290 is, for example, a metal plate-like member formed by sheet metal, and a beam structure that also serves as a part of the support frame 201 is formed by being installed in the middle of the support frame 201. ing. Further, the reel base 280 of each reel 21a, 21b, 21c is inserted between the top plate member 290 and the bottom plate member 210 installed on the support frame 201, and the upper and lower lock pins 24a, 24b of each reel base 280 are inserted. 24c, 23a, 23b, and 23c are respectively pushed into the locking holes of the top plate member 290 and the bottom plate member 210, thereby fixing the reels 21a, 21b, and 21c. Thus, by making the reel unit 20 a part of the support frame 201, the structure of the reel assembly 200 can be simplified and the overall weight can be reduced. Thereby, for example, the separation and mounting operations of the reel assembly 200 can be facilitated, or the number of parts can be reduced as compared with the related art.

  Next, the assembly of the slot machine 1 by each separation unit having the above-described structure will be described.

[Reel assembly installation]
First, installation of the reel assembly 200 in the housing 100 will be described. Here, FIG. 19 shows one guide (right side when the game machine is viewed from the front) in a state where the reel assembly 200 is installed on the reel base plate 105 provided between the left and right side plates 102 of the housing 100. It is a longitudinal cross-sectional view of the part cut | disconnected in the position of the support part 110. FIG. With reference to FIG. 9 and FIG. 9 already shown, in a state where the reel assembly 200 is installed at a predetermined position in the housing 100, the roller 226 attached to the bottom plate member 210 of the reel assembly 200 is moved to the reel base plate 105. At the same time, the housing side roller 116 is fitted into the notched portion 224 of the bottom plate member 210, and the mounting plate 222 of the bottom plate member 210 is placed on the supporting plate 112 on the housing side. Accordingly, the reel assembly 200 is stably held on the reel base plate 105 in the housing 100.

  When the reel assembly 200 is mounted on the housing 100, the guided side plate 221 of the bottom plate member 210 of the reel assembly 200 is inserted between the respective guide side plates 111 that are bent vertically on both sides of the reel base plate 105, and the housing 100. 20, the roller 226 of the reel assembly 200 is placed on the support plate 112 of the reel base plate 105 and the placement plate 222 on the reel assembly 200 side is placed on the roller 116 as shown in FIG. Put. As a result, the main body of the reel assembly 200 is supported at four points by freely rotating rollers 116 and 226, and the mounting plate 222 on the reel assembly side floats in a non-contact state with respect to the support plate 112 on the housing side. It becomes. As is clear from FIG. 20, the height position where the rear roller 226 is supported by the support plate 112 is lower than the height position where the front roller 116 supports the mounting plate 222. Has been. Therefore, the reel assembly 200 can be easily moved to the installation position at the back of the housing 100 with its own weight while rolling the rollers 116 and 226. Further, the outer side surfaces of the left and right guided side plates 221 of the bottom plate member 210 are inserted between the left and right guide side plates 111 of the reel base plate 105 and slidably move in the front-rear direction. The assembly 200 is accurately guided to a predetermined installation position. This facilitates positioning when the reel assembly 200 is mounted, and allows the mounting operation to be performed easily and quickly.

  Further, when the reel assembly 200 is separated from / removed from the housing 100, the roller 226 in the recess 114 of the reel base plate 105 rolls by pulling the reel assembly 200 forward of the housing 100. The inclined plate 113 climbs up and at the same time the inclined plate 223 on the reel assembly 200 side rides on the roller 116 on the reel base plate 105 side, so that the mounting plate on the reel assembly side with respect to the reel base plate 105 (support plate 112). 222 is in a floating state. If the reel assembly 200 is further pulled out in this state, it can be easily and quickly detached and detached from the housing 100 by the freely rotating rollers 116 and 226.

  When the reel assembly 200 is installed at a predetermined position in the housing 100, the left and right vertical front frames 201 b of the reel assembly 200 are locked to the locking tools 120 attached to the both side plates 102 of the housing 100. The hooks 241 and 251 are locked and held.

  Here, FIG. 21 is a perspective view of the locking tool 120, and the structure of the locking tool 120 will be described with reference to FIG. The locking member 120 includes a base member 121 formed by bending a metal plate material into a substantially U-shaped cross section, and is similarly formed by bending a metal plate material into a U-shaped shape. A lever member 122 that is pivotably mounted in the horizontal direction, a vertical shaft 127 that is inserted into a shaft hole formed substantially at the center of the upper and lower bent portions of the lever member 122 and is pivotally mounted, and a vertical shaft 127 Two orthogonal rotation arms 126, an expansion / contraction arm 125 attached to the rotation arm 126 so as to be extendable / contractable, and a coiled spring 128 that constantly urges the expansion / contraction arm 125 toward the rotation arm 126 (degenerate side). And a round bar-like locking bar 124 for connecting the ends of the respective extendable arms 125 to each other. Note that the locking member 120 is fixed to each predetermined position of the both side plates (102) of the housing (100) by screwing the bottom of one side of the base member 121.

  FIG. 22 is a cross-sectional view illustrating a state in which the right hook 251 of the reel assembly 200 is locked to the locking tool 120 fixed to the housing 100. When the reel assembly 200 is inserted from the opening side of the housing 100 and reaches a predetermined installation position, the rear end portion of the vertical front frame 201b of the support frame 201 is formed with a stepped portion 102a formed at the front end of the side plate 102 of the housing 100. To fit. In this state, the lever member 122 of the locking tool 120 is rotated, the locking bar 124 is hooked on the locking hook 251 fixed to the front frame auxiliary metal fitting 250, and the lever member 122 is tilted to the base member 121 side. As a result, the contraction elastic force of the spring 128 acts on the locking hook 251 via the locking bar 124 and pulls the entire reel assembly 200 toward the housing 100 side. As a result, the reel assembly 200 is held from being detached from the housing 100.

  When the reel assembly 200 that can be attached to and detached from the housing 100 is correctly installed in the housing 100, the reel assembly 200 is sealed through the sealing means shown in the front view of FIG. 23 and the cross-sectional view of FIG. This sealing means is provided to manage the separation / desorption history of the reel assembly 200 from the casing 100 and to quickly detect unauthorized desorption. That is, the reel assembly 200 cannot be separated from the casing 100 unless the sealing state by the sealing means is released, and once the reel assembly 200 is separated from the casing 100, a trace is left. It is like that.

  Here, an embodiment of the sealing means will be described with reference to FIGS. This sealing means includes an extension part 31 a in which one end of the main board case 31 extends toward the top plate 101 of the casing 100 and is formed in a trapezoidal shape, and is fixed to the casing 100 and is fixed to the main board case 31. The sealing base member 202 is connected to the extending portion 31a with screws, and the sealing sheet 33 is attached to the extending portion 31a and the front surface of the sealing base member 202.

  The sealing base member 202 is screwed to the back plate 104 of the housing 100 via a housing connecting portion 202a which is a bottomed circular groove recessed at the center. Further, a stepped portion 202b is formed on the lower front side of the sealing base member 202, and the extending portion 31a of the main substrate case 31 is disposed in front of the stepped portion 202b. A screw hole penetrates one side of the extended portion 31a of the main board case 31, and a screw is screwed into a screw boss 202c formed on the stepped portion 202b side through the screw hole. The extension part 31a is fastened. Then, a sealing sheet 33 made of, for example, rectangular synthetic paper is closed so as to cover the housing connecting portion 202a and the screw head screwed into the screw boss 202c, and the extension portion 31a and the sealing base member 202 are covered. It is sealed by sticking to each front surface with an adhesive or the like.

  The main board case 31 is integrally attached to the support frame 201 of the reel assembly 200 through the bracket members (32a, 32b) so as not to be detached, so that the reel assembly 200 is separated from the housing 100. When detaching, the sealing sheet 33 must be cut or peeled off to release the sealed state. Thus, since the reel assembly 200 is sealed with respect to the housing 100 through the sealing means, whether or not there is a history of the reel assembly 200 being illegally removed before is seen from the state of the sealing sheet 33. Simple and reliable discrimination is possible.

[Attaching the lower mask unit]
Next, attachment of the lower mask unit 400 to the housing 100 will be described. Here, FIG. 25 is a diagram showing the structure of the front surface of the housing 100 and the back surface of the lower mask unit 400. FIG. 26 is a cross-sectional view showing a structure of a hinge mechanism for attaching the lower mask unit 400 to the housing 100 so as to be opened and closed.

  As described above, the lower door hinge bracket 420 and the lower door lock bracket 430 are attached to the left and right side frames on the back surface of the lower mask unit 400, respectively. The lower door hinge bracket 420 has support portions 421 formed at two locations corresponding to the hinge pins 141 of the housing auxiliary bracket 140. As shown in FIG. 26, the support portion 421 has a substantially horizontal support surface orthogonal to the opening / closing axis and a hinge hole 421a at the center thereof. When the lower mask unit 400 is attached to the housing 100, the hinge pins 141 of the housing auxiliary metal fitting 140 are inserted into the respective hinge holes 421a formed in the lower door hinge metal fitting 420 of the lower mask unit 400 for support. The lower mask unit 400 is attached to the hinge pin 141 so as to be openable and closable by the support surface of the portion 421 being supported by contacting the shoulder 141a of the hinge pin 141.

  Next, a lock mechanism that locks the lower mask unit 400 in the closed state to the housing 100 will be described. FIG. 27 is a perspective view showing a locked state between the case auxiliary metal fitting 130 provided at the left end of the opening of the case (100) and the lower door lock metal fitting 430 of the lower mask unit (400). FIG. 5 is a side view of the housing auxiliary metal fitting 130 and the lower door lock metal fitting 430 in a locked state.

  Referring to these drawings, the case auxiliary metal fitting 130 has a substrate 132 made of a metal plate that is long in the vertical direction, and the rear end is bent inward of the case opening at two predetermined positions. Thus, a lock plate 131 is formed. In addition, a roller guide 133 for guiding and supporting a roller 436 provided on the lower door lock fitting 430 on the lower mask unit (400) side is provided below the substrate 132. When the lower mask unit is closed to the housing, the roller guide 133 supports and rolls the roller 436 on the lower mask unit side on its upper surface, guides it to a predetermined closing position, and closes the lower mask unit. At regular times, part of the load is supported to reduce the load applied to the hinge mechanism.

  On the other hand, the lower door lock metal fitting 430 is pivotally attached to the base body 435 so as to correspond to the lock plate 131 and the cylinder lock 432, the base body 435 made of a long metal plate in the vertical direction. The two flange members 431 and a roller 436 pivotally supported at the lower portion of the base 435 are mainly configured.

  The eaves member 431 is formed of a metal plate, and has an inclined edge 431a that is tapered toward the lock plate 131 and a vertical edge 431b that linearly descends from the highest end of the inclined edge 431a. Each flange member 431 is connected via a link bar 434 accommodated in the base body 435 and is configured to rotate in conjunction with the vertical movement of the link bar 434.

  The link bar 434 is engaged with an ankle member 433 that rotates in accordance with the operation of the cylinder lock 432, and is formed to move up and down in conjunction with this rotation operation. In other words, in a normal state (without operation), the ankle member 433 is held at a predetermined rotational position by the urging means built in the cylinder lock 432, whereby the link bar 434 is moved to the upper position (see FIG. 28). Thus, the flange member 431 is held at a pivot position where the lock plate 131 is locked substantially horizontally. Further, when the regular key KEY is inserted into the cylinder lock 432 through the key hole 16 formed on the front console 7 and is rotated, for example, in the right direction against the urging force, the ankle member 433 is rotated. In conjunction with this, the link bar 434 moves to a lower position. At this time, the vertical edge 431b of each collar member 431 moves downward, the locked state with the lock plate 131 is released, and the lower mask unit 400 can be opened.

  Further, when the lower mask unit 400 is closed to the housing 100, these are automatically locked (locked). That is, when the lower mask unit 400 is closed to the housing 100, first, the inclined portion 431a of the flange member 431 rotates downward while following the inclined edge shape while contacting the lower edge of the lock plate 131. In a state where the lower mask unit 400 is completely closed to the housing 100 side, the lower edge of the lock plate 131 reaches the vertical edge 431b of the flange member 431, and the flange member 431 is transmitted via the ankle member 433 and the link bar 434. The urging force of the urging means of the cylinder lock 432 is applied and returned to the original substantially horizontal rotation position. As a result, the vertical edge 431b of the flange member 431 is engaged with the lock plate 131 on the housing side, and is locked.

  When the lower mask unit 400 is closed to the housing 100, the roller 436 on the lower mask unit side smoothly moves the upper surface of the roller guide 133 by the bent portion 133a inclined downward at the tip of the roller guide 133 on the housing side. Then, it rolls on the roller guide 133 and is guided to a predetermined closing position. Further, when the lower mask unit 400 is completely closed, the load of the lower mask unit is applied to the roller guide 133 via the roller 436, whereby the load of the lower mask unit supported by the hinge mechanism is dispersed. Therefore, the load load of the hinge mechanism in a steady state is reduced, and durability and the like are improved.

[Attaching the upper mask unit]
Next, attachment of the upper mask unit 300 to the housing (reel assembly 200) will be described. Here, FIG. 29 is a diagram showing the structure of the front surface of the housing 100 and the back surface of the upper mask unit 300. FIG. 30 is a perspective view showing a locked state of the front frame auxiliary metal fitting 240 provided on the left front frame of the reel assembly (200) and the upper door lock metal fitting 330 of the upper mask unit (300). These are side views of the front frame auxiliary metal fitting 240 and the upper door lock metal fitting 330 in a locked state.

  The upper mask unit 300 is attached to the housing 100 so as to be openable and closable via a hinge mechanism having a structure similar to that of the lower mask unit 400 described above. The upper mask unit 300 is attached to and detached from the housing 100 while the reel assembly 200 and the lower mask unit 400 are attached to the housing 100.

  As shown in FIG. 29, the front frame auxiliary metal fitting 250 of the reel assembly 200 is provided with two hinge pins 252, while the upper door hinge metal fitting 320 attached to the rear right frame of the upper mask unit 300 is provided. Are provided with support portions 321 at two locations corresponding to the hinge pins 252. The support portion 321 has a substantially horizontal support surface orthogonal to the opening / closing axis of the upper mask unit 300 and a hinge hole formed in the center thereof, and a hinge pin 252 on the reel assembly 200 side is inserted into the hinge hole of the support portion 321. At the same time, the upper mask unit 300 is attached to the housing 100 so as to be openable and closable by the support surface of the support portion 321 being abutted and supported by the shoulder portion of the hinge pin 252.
