Description

  The present invention relates to a slot machine that uses a game ball for a pachinko machine (hereinafter also referred to as “pachinko ball” or simply “game ball” as necessary) as a game medium.

  Slot machines that use pachinko balls as game media can be played using pachinko balls instead of medals that are used as game media in general slot machines. The player can enjoy both a pachinko machine and a slot machine game with a single type of game medium. In addition, this slot machine can be installed on a game island for pachinko machines and can use ball supply / recovery equipment for pachinko machines. There is also an advantage of becoming.

  The slot machine installed on such a pachinko machine amusement island has an outer frame formed in the same shape as the outer frame of the pachinko machine. It is fixed using tools. A front frame provided with a game operation unit and a ball storage tray is attached to the front surface of the outer frame so as to be openable and closable, and a reel unit having a plurality of rotating reels is disposed on the back side of the front frame. . Conventionally, the reel unit is arranged in such a manner that a panel support frame having an opening is attached to the back side of the inner frame corresponding to the front frame of the present invention, and the panel having the reel unit attached to the opening is attached and detached. The reel unit is directly attached to the back surface of the mechanism plate corresponding to the front frame of the present invention (for example, see Patent Document 2), or the front A device in which a reel unit is directly attached to the back surface of the middle frame provided on the back surface side of the frame (for example, see Patent Document 3) is known. In any case, the front frame as a support member Also, the front side of the reel unit is cantilevered and supported on the back of the middle frame.

On the other hand, in a slot machine using a pachinko ball as a game medium, if it is installed on a game island dedicated to this type of slot machine instead of a game island for a pachinko machine, the depth fixed to the game island 2. Description of the Related Art There is a known hollow box-shaped storage frame in which a mounting table is horizontally mounted on left and right side plates, and the mounting table is used as a mounting unit for a reel unit (see, for example, Patent Document 4).

  By the way, in addition to a plurality of rotating reels, the reel unit has a robust control board box that houses a plurality of reel driving motors for driving each rotating reel and a control board for controlling the rotation of each reel driving motor. Since the unit is arranged at a predetermined position of the storage frame, it has a considerable weight. Therefore, as described above, in the configuration in which the front side of the reel unit is cantilevered and supported on the back of the front frame and the middle frame as the support member, the bottom of the reel unit is supported. Therefore, the installation state and the rotation state of the rotary reel become unstable, and the weight of the reel unit is concentrated on the attachment part with the front frame and the middle frame, and the rotation moment always acts, so that the attachment part There was a problem that deformation and breakage were likely to occur.

  In addition, since the reel unit is moved together during the opening / closing operation of the front frame at the time of maintenance, there is a problem that the opening / closing operation is difficult because the front frame is heavy. Furthermore, when replacing with a new model (equivalent to changing the pachinko machine panel), remove the reel unit, control board, etc. individually from this heavy front frame, remove the front frame, Since the work of attaching the frame and individually attaching the reel unit, the control board, and the like is performed, there is a problem that the work is complicated.

  On the other hand, in the configuration in which the storage frame is formed in a hollow box shape having a depth and the mounting table is horizontally mounted on the left and right side plates, the above-described problems do not occur. On the other hand, because the shape of the storage frame is significantly different from the shape of the outer frame for pachinko machines, not only can this storage frame not be used as an outer frame for pachinko machines, but it cannot be installed on amusement islands for pachinko machines. There was a problem.

  In the present invention, a stable reel unit installation state can be obtained, maintenance work, replacement work to a new model, etc. can be easily performed, and an outer frame can be used in common between a slot machine and a pachinko machine. It is an object to provide a slot machine.

  The present invention plays a game using a game ball for a pachinko machine as a game medium, and is fixed to a game island for a pachinko machine, and an outer frame having a curtain placed on the front surface of the lower end of the frame; In a slot machine comprising a front frame attached to the front surface of the outer frame so as to be openable and closable, a back mechanism plate attached to the rear side of the front frame, and a reel unit, Left and right vertical saddles that are shorter than the side flanges, supported by the inner surface of the flange, and laterally supported by the outer surface of the bottom flange that is hidden behind the curtain. A metal inner frame composed of a flange, and a disengagement means for allowing the metal inner frame to be engaged with and disengaged from the outer frame, and a left and right of the metal inner frame via the support bracket A mounting table that is held substantially horizontally between the vertical flanges is provided on a metal inner frame, and the reel unit is held on the mounting table. It is a slot machine, characterized in Rukoto (claim 1). Here, the said outer frame is a wooden rectangular frame shape, and is formed in the same shape as the wooden outer frame for pachinko machines.

  In such a configuration, the metal inner frame body is inclined downwardly from the front surface side of the outer frame toward the rear of the outer frame to the outer frame in which the curtain plate is disposed on the front surface of the lower end portion of the frame. After the recumbent part is inserted on the back side of the curtain, the recumbent part is supported on the reed upper surface of the bottom reed part of the outer frame by standing and the left and right vertical reed parts are respectively left and right of the outer frame. A metal inner frame body can be attached to the inner side of the outer frame so as to be supported on the inner surface of the side flange portion. Conversely, after the metal inner frame is tilted downward and the upper parts of the left and right vertical hooks protrude to the front side of the outer frame, the metal inner frame can be removed from the outer frame to the front side in the tilted state. it can. Here, since the metal inner frame body is constituted by the left and right vertical saddle portions which are shorter than the left and right side flanges of the outer frame, when being attached to the outer frame, it is inclined with respect to the outer frame. It is possible to easily erect or incline from a standing state when removing. And since the metal inner frame can be attached from the front side and locked to the outer frame by the engaging / disengaging means, the metal inner frame can be fixed to the outer frame. Furthermore, since the engagement with the outer frame can be released from the front side by the engagement / disengagement means, these attachment work and removal work can be easily and appropriately performed.

  In addition, as described above, the metal inner frame is supported by the outer surface of the left and right vertical frame portions being in contact with the inner surfaces of the left and right side flange portions of the outer frame, and the horizontal flange portion is outside. It is configured to be in contact with and supported by the upper surface of the bottom flange of the frame. The metal inner frame is provided with a mounting table held via a support bracket, and a reel unit is held on the mounting table. As a result, the weight of the reel unit held on the mounting table is distributed to the left and right side flanges and the bottom flange of the outer frame via the metal inner frame, so that the reel unit is held firmly. Therefore, the swinging of the rotating reel during rotation is suppressed, and the rotating state of the rotating reel can be stabilized. Further, since the heavy reel unit is not disposed on the front frame side, the opening and closing operation of the front frame during maintenance can be easily performed. Furthermore, it is possible to support various types of models by appropriately changing the shape of the support bracket and mounting table according to the shape of the ball supply mechanism of the back mechanism plate attached to the back side of the front frame. is there.

  Such a metal inner frame can be attached to and removed from the outer frame while holding the reel unit in advance, as well as being able to hold and remove the reel unit while attached to the outer frame. It is also possible. As a result, when replacing with a new model (equivalent to changing the board of a pachinko machine), it can be replaced by replacing the metal inner frame holding the reel unit. The exchange work in the amusement store can be easily performed, and the burden on the operator can be reduced. In addition, by performing the work of holding the reel unit on the metal inner frame in advance in the factory, it is possible to hold the reel unit accurately and firmly as compared with the case of performing the installation work in the amusement store. Even when the reel unit is held on the metal inner frame in the factory, the reel unit can be stably installed by attaching the metal inner frame to the outer frame. .

  Here, the mounting table on which the reel unit is mounted is attached to the metal inner frame body via the support bracket, and the metal inner frame body is attached to the outer frame. Therefore, the outer frame itself is separately processed. When the metal inner frame is removed from the outer frame, the outer frame can be used as an outer frame for a pachinko machine.

  In such a slot machine, the metal inner frame is formed in a substantially U shape in which the vertical hooks are coupled to the left and right sides of the horizontal hook, and at least at the rear upper end of the vertical hook. A flank is formed so as not to cause interference with the upper part of the outer frame when tilted to the front side with the lower part of the vertical saddle part as a fulcrum, and the support brackets attached to both vertical part parts respectively. A configuration is proposed in which the mounting table is fixed in a double-sided manner (claim 2).

  In this way, when the metal inner frame has a substantially U shape and the flank is formed at the rear upper end of the vertical saddle portion, when the metal inner frame body is attached to the outer frame from the front side, the vertical flange portion The upper part of the metal inner frame is in contact with the upper part of the outer frame when it is tilted downward after inserting it downward with the lower part of the fulcrum as a fulcrum, or when it is tilted downward when removing it from the front side. Without making it stand up or tilted relatively easily. In addition, since the mounting table is fixed to both the vertical flanges by the support brackets, the reel unit installation state and the rotating reel are provided even in the substantially U-shaped metal inner frame. Can be sufficiently stabilized.

  Further, in the slot machine described above, the engagement / disengagement means provided on the metal inner frame body is urged outward, and the elastic locking piece abutting on the back side edge of the side flange portion of the outer frame, It is composed of an engagement / disengagement member composed of a flange part that contacts the front edge of the frame frame, and the engagement / disengagement member holds the side frame part of the outer frame from the front and back sides by the elastic locking piece and the flange part, A configuration is proposed in which the metal inner frame is locked to the outer frame (claim 3).

  In such an engagement / disengagement member, when it is attached to the outer frame or removed, the elastic locking piece is moved inward (opposite to the urging direction) against the urging force, as described above. In addition, it is possible to easily perform an operation of attaching or removing the metal inner frame body by inclining downward from the front side of the outer frame to the rear side. Further, the side hooks are sandwiched from the front and back sides by the elastic locking pieces and the hooks, and the metal inner frame is fixed to the outer frame. It is also fixed in the front and back direction (front-rear direction). As described above, the metal inner frame is supported by the outer frame, and the metal inner frame can be held more firmly. In addition, the engaging / disengaging member comprising the elastic locking piece and the collar portion is compared to the case where the metal inner frame is fixed to the outer frame with screws or nails as the engaging / disengaging means described above. There is no problem that the positional relationship between the outer frame and the metal inner frame is shifted or the fixing operation is mistaken at the time of fixing operation such as screws and nails. Furthermore, since there is no use mark such as a screw or a nail remaining on the outer frame, there is an excellent advantage that damage to the outer frame can be prevented even after a plurality of replacement operations.

  Here, the present invention shares the outer frame with the pachinko machine as described above. In general, the outer frame on which the pachinko machine is installed is located forward so that the game ball can flow down and roll appropriately and smoothly in a game area composed of game nails, a center case, etc. arranged on the game board. It is tilted and fixed on the amusement island. For this reason, when the metal inner frame body is attached to the outer frame by providing the elastic locking piece so as to contact the back side edge of the side flange portion of the outer frame, The inner frame body can be reliably prevented from falling forward. Moreover, in the collar part which contact | abuts the front side edge of the side collar part of an outer frame, when a front frame is closed, it will be clamped by this front frame and an outer frame. This further improves the stability of the metal inner frame.

  In addition, a configuration is proposed in which the above-described support bracket is provided with an avoidance portion that avoids interference with the vertical spherical channel formed in the back mechanism plate (claim 4). In such a configuration, the avoidance unit can prevent the support bracket from interfering with the spherical flow path of the back mechanism plate. That is, a ball tank for storing a game ball supplied from a ball supply facility on a game island is provided on the upper part of a normal back mechanism plate, and a ball in a vertical direction that causes the game ball to flow down from the ball tank. The flow path is formed so as to reach below the height position of the reel unit. Therefore, it is not necessary to change the configuration of the normal back mechanism plate by providing the support bracket with an avoidance portion that avoids interference with the spherical flow path.

  On the other hand, a configuration is proposed in which the above-described metal inner frame body is provided with a substrate storage portion for sealingly mounting a control substrate for controlling a game between the left and right vertical saddle portions (claim 5). Here, when the slot machine is converted to a new model, members depending on the model are exchanged. For example, a decorative panel with model-specific designs and decorations such as model names and characters, various control boards such as a main control board that controls the slot machine, a design control board, and a sound lamp control board, and a plurality of designs are drawn. A reel unit having a rotating reel. For this reason, when replacing models, it is necessary to transport a large number of replacement parts. In particular, the control board, which is a precision machine, is carefully packed in a dedicated transport box, etc., so that it will not break down during transport. ing. In such a configuration, when exchanging the model, the control board is sealed and attached to the board storage part disposed in the metal inner frame, so that the dedicated transport box or the like is used from the factory to the game hall. Even if not, it can be safely transported. It is also possible to prevent the control board from being lost during transportation. Here, it is possible to adopt a configuration in which the board storage unit is simply used for transportation and the control board is detached from the board storage unit and attached to a predetermined position of the front frame when the board storage unit is attached to the game island. Alternatively, the control board can also be installed by setting the board storage unit as it is as the position of the control board and attaching the metal inner frame to the outer frame. In the former configuration, since the control board for each model is clarified, it is possible to prevent the wrong type of control board from being attached when the control board is attached. On the other hand, in the latter configuration, the replacement work can be further reduced because the control board can be installed by replacing the metal inner frame in which the control board is held in advance. Some control boards may be set in advance as arrangement positions as in the latter configuration, and other control boards may be transported and reattached as in the former configuration.

  Furthermore, in such a configuration, it is also possible to connect a plurality of control boards in advance with a cable for wiring, which can further reduce the work burden at the time of model replacement and prevent erroneous wiring. . In addition, since the board storage unit seals and attaches the control board, it is possible to prevent acts such as illegally replacing the control board during transportation. As a method for sealingly mounting the control board, for example, in a state where the control board is mounted on the board storage portion, both are fixed with a one-way screw, and a sealing wall is provided in a moving direction for removing the one-way screw. When the one-way screw is removed, the sealing wall is broken so that the removed fraud can be clearly recognized.

  A configuration is proposed in which the above-described substrate storage unit is fixed below a mounting table provided in a metal inner frame, and the control substrate can be attached and detached from the rear of the metal inner frame (Claim 6). . In such a configuration, the control board can be installed together with the reel unit by attaching the metal inner frame body to the outer frame, and the replacement work of the control board can be further reduced. In addition, since the control board can be mounted and removed only from the rear side of the metal inner frame, it cannot be removed from the front side when the metal inner frame is attached and fixed to the outer frame. . Accordingly, it is possible to prevent an illegal act such as opening the front frame and illegally exchanging the control board in a state of being attached to the game island.

  As described above, the slot machine of the present invention is supported by the inner surfaces of the left and right side flanges of the outer frame, and has a left and right vertical flange portion shorter than the side flanges, and the outer frame. , Comprising a metal inner frame body composed of a horizontal flange portion supported on the upper surface of the bottom flange portion hidden behind the curtain plate, and the metal inner frame body can be engaged with and disengaged from the outer frame And a mounting table that is held substantially horizontally between the left and right vertical flanges of the metal inner frame body via the support bracket, provided on the metal inner frame body, Since the reel unit is held on the front (Claim 1), it is possible to easily attach or remove the metal inner frame from the front side of the outer frame. Further, since the reel unit can be securely held on the outer frame via the mounting table and the metal inner frame, the rotation state of the rotary reel can be stabilized. Further, since the heavy reel unit is not disposed on the front frame side, the opening and closing operation of the front frame during maintenance can be easily performed. Furthermore, since the metal inner frame holding the reel unit can be attached to or removed from the outer frame, the heavy reel unit can be replaced relatively easily. Here, since the reel unit is attached to the metal inner frame in advance in the factory, it can be held accurately and firmly as compared with the case where it is attached in the game hall.

  The metal inner frame body described above is formed in a substantially U shape in which a vertical hook portion is coupled to the left and right sides of the horizontal hook portion, and a lower portion of the vertical hook portion is provided at least at the rear upper end of the vertical hook portion. A flank that prevents interference with the upper part of the outer frame when tilted to the front side as a fulcrum is formed, and the mounting table is held in both ends by the support brackets attached to both vertical flanges In the structure (Claim 2) that is fixed, when attaching or removing from the front side of the outer frame, the upper end of the metal inner frame does not contact the upper part of the outer frame, and these operations are performed. It can be done easily. In addition, since the mounting table is fixed to both vertical flanges in a double-sided manner, the installation state of the reel unit and the rotation state of the rotary reel can be sufficiently stabilized.

  Further, the engaging / disengaging means provided on the metal inner frame described above is biased outwardly and is provided with an elastic locking piece that contacts the back side edge of the side frame part of the outer frame, and the front side edge of the frame frame. The engagement / disengagement member is composed of an engaging / disengaging member, and the engagement / disengagement member sandwiches the outer flange from the front and back sides with the elastic locking piece and the flange, so that the inner frame is made of metal. In the configuration in which the frame is locked (Claim 3), the work of attaching or removing the metal inner frame from the front side by moving the elastic locking piece inward When attached, the side hooks can be clamped from the front and back sides by the elastic locking pieces and the hooks, so that the metal inner frame can be firmly fixed and held on the outer frame. . Moreover, since this engagement / disengagement member can fix a metal inner frame body in the state supported by the inner surface of the outer frame, the positional relationship between them does not cause problems such as slell. Further, since it is not necessary to make a hole in the outer frame, etc., there is an excellent advantage that damage to the outer frame can be prevented even after a plurality of replacement operations.

  Further, in the configuration in which the above-described support bracket is provided with an avoidance portion for avoiding interference with the vertical spherical flow path formed on the back mechanism plate (Claim 4), the support bracket is the back mechanism. Interference with the spherical flow path of the plate can be prevented by the avoidance unit. Therefore, it is not necessary to change the configuration of the normal back mechanism plate.

  Further, in the configuration (Claim 5), the above-described metal inner frame body is provided with a substrate storage portion for sealingly mounting a control substrate for controlling the game between the left and right vertical saddle portions. When replacing the model, the control board is securely mounted from the factory to the amusement hall without using a dedicated transport box by sealingly mounting the control board on the board storage part arranged on the metal inner frame. it can.

  Here, the substrate storage portion is fixed below the mounting table provided in the metal inner frame, and the control substrate can be attached and detached from the rear of the metal inner frame (Claim 6). Can attach this control board by attaching a metal inner frame to the outer frame, and can further reduce the work of replacing the control board. In addition, since the control board can be attached or removed only from the rear side of the metal inner frame body, it can be removed from the front side when the metal inner frame body is attached to the outer frame. Therefore, it is possible to prevent an illegal act such as opening the front frame and exchanging the control board illegally.

  Here, the display control board 102 is provided with four fixing screw hole portions 96 protruding outward at front and rear positions of the lower side edges. By screwing the fixing screw hole portion 96 to the substrate support portion 86a, the display control substrate 102 is fixed to the substrate storage portion 86 as shown in FIG. In this embodiment, after the display control board 102 is fixed, a sealing tape is attached to the rear part of the board housing portion 86 (not shown), and the display control board 102 is sealed and attached. This prevents the display control board 102 from being illegally removed before the metal inner frame 74 is disposed on the outer frame 2.

  Note that, as shown in FIG. 21, a wiring cable 97 for connecting to another control board provided in the board unit 38 provided on the back mechanism plate 37 is attached to the display control board 102 in advance. . Then, when the metal inner frame 74 is transported from the factory to the game hall and attached to the outer frame, the wiring cable 97 is connected to another control board of the board unit 38 to facilitate installation work. It can be carried out.

  Furthermore, as shown in FIG. 18, the metal inner frame 74 is provided with two substrate storage portions 87 and 87 for mounting the control substrate on the upper surface of the horizontal flange portion 74b. The board storage portions 87 and 87 are provided with storage recesses 87a and 87a that are opened upward, and the control board can be inserted into and mounted in the storage recesses 87a and 87a. The housing recess 87a is inserted into the two fixing screw hole portions 96 provided at the lower part in the insertion direction among the four fixing screw hole portions 96 formed on both sides of the control board. It is formed to a depth that can be achieved. A screw insertion hole 98 into which the one-way screw 99 is inserted is provided on both the front and rear sides of the storage recess 87a facing the fixing screw holes 96, 96, and is a cross-sectional view of the substrate storage part 87 shown in FIG. As described above, the boss portion 98 a provided with the female screw of the one-way screw 99 is provided at a position in surface contact with the front surface side of the fixing screw hole portion 96. Further, the rear screw insertion hole 98 is formed with a sealing wall portion 98b that can be broken by screwing the one-way screw 99. That is, after a predetermined control board is inserted into the housing recesses 87a and 87a of the board storage portions 87 and 87, as shown in FIG. 19 (a), the one-way screw 99 is inserted from the front through the screw insertion hole 98, and FIG. As shown in (b), the control board is sealed and attached to the board storage part 87 by screwing the boss part 98a and the fixing screw hole part 96 of the control board. Here, since the one-way screw 99 can be screwed only in one direction, in order to remove the control board from the board housing portion 87, the one-way screw 99 is moved as shown in FIG. It must be screwed off and removed from the opposite side of the screw insertion hole 98, and the sealing wall portion 98b may be broken. Therefore, when the control board is illegally removed from the board storage portion 87, the sealing wall portion 98b is broken, so that the occurrence of the illegality can be clearly recognized.

  As described above, since the board storage portions 87 and 87 are provided in the horizontal portion of the metal inner frame 74 (see FIG. 18B), the control board is enclosed and attached to the board storage portions 87 and 87. Can be transported to the amusement hall. Here, in the embodiment, the main control board 100 and the sound lamp control board 103 described above are encapsulated in the board storage portions 87 and 87 and transported. The main control board 100 and the sound lamp control board 103 were removed from the board storage portion 87 and provided on the above-described back mechanism plate 37 when the metal inner frame 74 was transported to the amusement hall to exchange models. Arranged on the substrate unit 38. As described above, since the control board can be transported by being enclosed in the board storage portion 87 of the metal inner frame 74, as described above, these control boards can be illegally replaced during transport. It can be prevented and can be transported safely without using a transport box dedicated to the control board.

  As described above, the reel unit 62 is placed on the main plate portion 66a of the placing table 61 disposed in the metal inner frame 74 (see FIG. 5). Here, at the lower front edge of the storage frame 64 constituting the reel unit 62, as shown in FIG. 18, a mounting flange portion 69 is projected downward, and the mounting flange portion 69 is connected to the front wall of the mounting table 61. The reel unit 62 is fixed to the mounting table 61 by being fixed to the portion 66b using screws or a dedicated fixing tool.

Next, a process of attaching the metal inner frame 74 described above to the outer frame 2 disposed on the game island will be described.
In the case of replacement with a new model, a substrate in which the reel unit 62 is fixed to the mounting table 61 in advance and the display control substrate 102 is suspended on the mounting table 61 in the metal inner frame 74 of the new model. The main control board 100 and the sound lamp control board 103 are enclosed and mounted in the board storage parts 87 and 87 of the recumbent part 74b (FIG. 18 (b)). To be transported.

  The metal inner frame body 74 thus transported to the amusement hall is attached to the predetermined outer frame 2. That is, as shown in FIG. 20, the metal inner frame 74 is inclined downward toward the rear. Then, as shown in FIG. 20B, the outer frame 2 is caused to enter the outer frame 2 so as not to contact the curtain plate 22 of the outer frame 2. At this time, in the engaging / disengaging members 90, 90 provided at the lower portions of the left and right vertical flange portions 74a, 74a, the locking piece portions 92a of the respective elastic locking pieces 92 are tilted inward. With the recumbent portion 74b getting over the curtain plate 22, the metal inner frame 74 is arranged so that the upper ends of the vertical reed portions 74a and 74b do not contact the upper reed portion 2b of the outer frame 2. Tilt and stand up with the lower part of the frame 74 as a fulcrum. As a result, as shown in FIG. 20C, the horizontal flange portion 74b is in surface contact with the upper surface of the bottom flange portion 2c of the outer frame 2 and is surface-supported, and the vertical flange portions 74a and 74a on both the left and right sides are The left and right side flanges 2a, 2a are in surface contact with the inner surfaces of the flanges and are supported on the surfaces. Here, when the metal inner frame 74 is tilted while standing up from the downwardly inclined state, the engaging / disengaging members 90, 90 on the left and right vertical flange portions 74 a, 74 a are also locked to the elastic locking pieces 92. Each piece 92a is tilted inward. Then, the four locking pieces 92a tilted inward return to a stable state flush with the vertical flanges 74a and 74a when the metal inner frame 74 is in an upright state, and the outer frame 2 While engaging with the back side edge of the side collar part 2a, 2a, the collar part 91 engages with the front side edge of the side collar part 2a, 2a. As a result, the engagement / disengagement member 90 of the metal inner frame 74 sandwiches the left and right side flanges 2a, 2a of the outer frame 2 in the front / back direction (front / rear direction). The frame 2 is fixed and held. In this manner, the metal inner frame 74 is attached to the outer frame 2 with the reel unit 62 and the control board arranged as shown in FIG.

  The main control board 100 and the sound lamp control board 103 encapsulated in the board storage portions 87 and 87 of the horizontal flange 74b of the metal inner frame 74 are attached to the metal inner frame 74 and the outer frame 2. Either before or after attachment, it is removed and placed on the substrate unit 38 of the back mechanism board 37.

It connects with the other control board arrange | positioned at the board | substrate unit 38 of the board 37 (illustration omitted).

  On the other hand, when removing the metal inner frame 74 attached to the outer frame 2 as described above, the elastic locking piece 92 of the engagement / disengagement member 90 is tilted inward, and the metal inner frame 74 is removed. 74 is inclined downward toward the rear with the lower part as a fulcrum, and the upper parts of the vertical flange parts 74a, 74a are taken out to the front side of the outer frame 2 (see FIG. 20B). Then, the metal inner frame 74 is pulled out from the outer frame 2 and removed so that the horizontal flange 74b does not come into contact with the curtain plate 22 of the outer frame 2 in the state of being inclined downward. After removing in this way, the work for changing to a new model can be performed by attaching the metal inner frame 74 of a new model as described above.

  As described above, according to the present invention, the reel unit is mounted on the mounting table 61 that is held by the support brackets 60, 60, and the display control board 102 is mounted on the substrate storage portion 87 fixed to the mounting table 61. A substantially U-shaped metal inner frame body 74 in which is attached can be attached and detached from the front side of the outer frame 2. This makes it possible to easily and properly attach the metal inner frame 74 on which the reel unit 62 and the display control board 102 are previously arranged at the factory to the outer frame 2 when changing the model. As in the conventional configuration, the work of attaching the heavy reel unit 62 to the front frame 4 and the work of attaching the display control board 102 to the board unit 38 of the back mechanism board 37 can be omitted. Further, the reel unit 62 and the display control board 102 can be safely transported without having to be packed and transported in a dedicated transport box, and the transporting work can be reduced.

  The metal inner frame 74 is also provided with board storage portions 87 and 87 for transporting the control board disposed in the board unit 38, so that a dedicated transport box is used for the control board. Even without this, the control board can be safely carried. And since the board | substrate storage parts 87 and 87 carry out enclosure mounting | wearing of the control board | substrate with the one-way screw 99, it can also prevent that it replace | exchanges illegally during conveyance. On the other hand, in the board storage part 86 fixed to the mounting table 61 described above, a control tape can be similarly attached to the rear side of the control board to prevent unauthorized replacement during transportation. ing. Furthermore, since the board storage portion 86 can only be attached and detached from the rear side, if the metal inner frame 74 is attached to the outer frame 2, the control board can be illegally removed or replaced. I can't.

  Furthermore, the metal inner frame body 74 is surface-supported on the inner surface of the left and right side flanges 2a, 2a of the outer frame 2 and the upper surface of the bottom flange, and on the left and right vertical flanges 74a, 74.
