  However, in the invention of Patent Document 1, when the front door is opened and the reel unit or the like is inspected or repaired, the main board is also fully visible, so it is convenient for inspection and repair, but if the front door is opened. Since the main board automatically becomes defenseless, there is a problem that it is difficult to effectively prevent illegal acts on the main board due to illegal nighttime intrusion, unauthorized opening during operation, and the like. In the invention of Patent Document 1, the effect can be exerted on the fraud performed by removing the control board device from the housing, but other types of fraud such as ROM exchange, hanging board, cell, etc.・ It may not be effective against fraudulent acts caused by the invasion of the piano wire, unauthorized setting changes caused by the goto acts, or the intrusion from the lower plate. In addition, the present invention is large and complicated, resulting in cost barriers, and it is difficult to implement effective measures at low cost.

  Therefore, an object of the present invention is to enhance the crime prevention effect of a spinning-rotor type gaming machine while considering convenience, operability, and cost.

  Complete crime prevention is considered to be practically difficult due to various circumstances, and there is no guarantee that security will be perfect even if the cost is increased. The gist of the present invention is to make it difficult to perform fraudulent activities while ensuring convenience, operability, and low cost.

  In view of the above-described problems, the swivel type gaming machine of the present invention includes a housing whose front surface is opened, and the housing as an upper chamber in which a main board is accommodated and a lower chamber in which a reel unit is accommodated. A partition plate that forms a partition; an upper door provided on a front surface of the upper chamber; and a lower door that opens and closes the front surface of the lower chamber; even if the lower door is opened, Opening is prevented, and the partition plate is structured to protect the main substrate.

  The “partition plate” may be flat or curved. The “partition plate” includes any of a transparent plate, a translucent plate, and an opaque plate. With the "partition plate", the upper chamber that accommodates the main board and the lower chamber that accommodates the reel unit are configured as independent chambers, and even if the lower door is opened for inspection, etc., unless the upper door is opened, The main board does not become fully visible, and it is difficult to perform an illegal act on the main board.

  The “closing portion” is preferably a lock provided on the upper door or a fastening part such as a screw or a screw for fixing the upper door to the housing. Fastening parts such as screws and screws can be preferably released. Moreover, it is preferable to provide a lock separately on the “upper door” and the “lower door”. Even if only the key of the upper lock is held, a structure in which the “upper door” is caught by the “lower door” and the “upper door” does not open alone is preferable. On the other hand, even if only the key for the lower lock is held, the “upper door” is closed by the “closing portion”, so that the “upper door” does not open independently. Moreover, since the use frequency of the upper lock is low and the use frequency of the lower lock is high, the security is enhanced by managing the keys of the upper lock and the lower lock separately.

  "Even when the lower door is opened, the upper door is prevented from being opened by the closing portion," when the lower door is opened, the upper door is physically blocked by the closing portion. It is.

  Further, it is preferable that the upper door does not open with the lower door closed, that is, the upper door does not open alone unless the lower door is opened. For example, the front of the lower edge of the upper door The upper door edge of the lower door is folded on the side.

  The “upper door” is preferably made of sheet metal, but may be made of other materials such as MDF (medium density fiberboard), paper, and synthetic resin. The “upper door” preferably includes a removal door in addition to the hinged door. The “upper door” may be a hinged door, and it may be fixed to the housing with screws, screws, bolts or other screwed parts to release the screwed parts in order to improve security. The door may be opened with a hinge, or a hinge and a screwed part may be combined.

  The “lower door” is preferably a hinged door to improve operability. The “lower door” is preferably a hinged door.

  The “housing” is preferably selected from sheet metal, MDF (medium density fiberboard), paper board, synthetic resin board, and the like.

  “Main board” is a board that has a function that affects or may affect the outcome of the game as defined in the game rules, and only the electronic parts for connecting the wirings to each other are mounted. Things other than things. The main substrate is preferably a transparent case, which is sealed to a case where the trace remains (referred to as “main substrate case”) by opening it for inspection or the like. Usually, a seal seal is affixed to the main board.

  As the “structure that protects the main substrate by the partition plate”, a structure that separates the “upper chamber” and the “lower chamber” by the “partition plate”, or a gap between the two chambers, Includes a structure for communicating. The gap may be any gap that hinders fraud, and for example, it is preferable that a hand or a fraudulent instrument cannot be inserted or is difficult. There may or may not be a gap between the left and right sides and the back side of the “partition plate”. A vertical plate as a protective wall may be provided in front of the “partition plate”. When the “partition plate” is a transparent plate, the visibility is excellent. However, when the “partition plate” is an opaque plate, in order to ensure the visibility of the main board, a gap that allows monitoring of the main board is provided to prevent fraud. A structure that can be inspected is preferred.

  Incidentally, in the invention of Patent Document 1, a display control device 601 is attached to the back surface of the upper door 13. In order to close the upper door 13, it is difficult to install the display control device 601 as wide as it can collide with the casing 11 on the rotation trajectory when the upper door 13 is closed. There is an inconvenience that the shape of the device 601 is restricted (the width is restricted or the shape must be round). Therefore, in order to eliminate such inconvenience that the device can be attached only in a small range, in the present invention, the display control device is accommodated in the upper chamber, or the accessory, the sound device, and / or the sub-board box. A structure in which such a device is installed is preferable. Thereby, the vacant space of the upper chamber can be used effectively. Moreover, a large apparatus can be accommodated in the upper chamber.

  The apparatus is preferably installed on the partition plate from the viewpoint of installation stability and the like. In addition, it is preferable that a display device or an accessory such as a liquid crystal display device is disposed in proximity to the upper door. Therefore, it is preferable to provide a window on the upper door.

  According to the first aspect of the present invention, the upper chamber that accommodates the main board is configured as a chamber independent of the lower chamber, and even if the lower door is opened, it is difficult to cheat on the main board in the upper chamber. It is possible to increase the crime prevention effect of the swivel type gaming machine at a low cost without reducing the operability.

The storage chamber 9 stores a hopper device (not shown) that pays out medals when winning. In addition, even when the lower-rotating game machine 1 opens the lower door 12, the upper door 11 is closed. The upper door 11 must be opened using a dedicated key for the key cylinder lock 13 provided on the upper door 11. The lower door 12 must be opened using a dedicated key for the key cylinder lock 14 provided on the lower door 12. Even when the lower door 12 is opened, the upper door 11 is closed with a key cylinder lock 13 which is an example of a closing portion of claim 1 and does not open. Further, the upper door 11 is prevented from being opened, and the upper chamber 3 is partitioned by the partition plate 5 to protect the main substrate 6.

  The lower door 12 is provided with a reel observation window 15 through which the player can partially observe the three reels of the reel unit 7. Below the reel observation window 15, a bet number display unit for displaying the number of medals bet by the player for each game, a payout medal number display unit for displaying the number of payout medals when winning is obtained, A display unit 16 including a credit number display unit for displaying the number of credited medals is provided on the front side. The lower door 12 is provided with a medal slot, a bet button, a stop button and a start lever corresponding to each reel, and a medal tray 17 is provided at the lower part. The upper door 11 is connected to the housing 2 so as to be opened and closed with a hinge (not shown). The lower door 12 is connected to the housing 2 by hinges 18 and 19. This will be described in detail below.

  As shown in FIGS. 2 and 3, the housing 2 is a vertically long rectangular box, and a rectangular front surface is opened. The housing 2 is preferably selected from sheet metal, MDF (medium density fiberboard), paper board, synthetic resin board, and the like.

  As shown in FIGS. 1 to 3, the volume of the upper chamber 3 is smaller than the volume of the lower chamber 4, and preferably the volume ratio is 1/3 or less, particularly 1/4 or less. The volume is set so that the substrate 6 can be appropriately accommodated.

  As shown in FIG. 2, the inside of the housing 2 is partitioned into an upper chamber 3 and a lower chamber 4 by a partition plate 5, and a main board 6 and a reel unit 7 are separately stored in each partitioned region. Yes. The main board 6 that performs electronic lottery and reel stop control is stored in a vertical direction in the back of the upper chamber 3 after being housed in a board case having a sealing function so that fraudulent acts are difficult. When the upper door 11 is closed, the main board 6 and the like above the partition plate 5 are covered. When the lower door 12 is closed, the power supply box 8 and the hopper device (not shown) on the upper and lower sides of the shelf board 10 are covered.

  The partition plate 5 is preferably selected from sheet metal, MDF (medium density fiber board), paper board, synthetic resin board, and the like.

  There are various structures for the partition plate 5. For example, as shown in FIGS. 2 and 4 (a), a rectangular partition plate 5 is horizontally arranged, and its rear edge and both side edges are fixed to the back side and both side faces of the housing 2, respectively. The thing which contacts the rear surface edge of the upper door 11 is mentioned. Further, as shown in FIG. 4B, a gap 53 may be formed on the front side of the partition plate 5 so that the upper chamber 3 and the lower chamber 4 communicate with each other. As shown in FIGS. 4 and 5, when the device 20 is accommodated, it is necessary to make the partition plate 5 longer than when the device 20 is not accommodated. As shown in FIG. 5, a vertical plate 54 may be erected as a protective wall at the front portion of the partition plate 5, and the crime prevention effect can be enhanced. As shown in FIGS. 6A and 6B, a cover plate structure in which the main substrate 6 is covered with the partition plate 5 may be employed. In this case, the space in which the main substrate 6 surrounded by the partition plate 5 is accommodated is the upper chamber 3. Further, as shown by the dotted line in FIG. 6, when the apparatus 20 is accommodated, the partition plate 5 may be added. In the case of FIG. 6, the partition plate 5 is fixed to the inner wall of the housing 2 with fastening parts such as screws. Here, the fastening parts can be removed.

  The main board 6 shown in the drawing is mounted with ROM using a socket or the like having a structure that does not obstruct the view of the plate surface of the main board 6. The main board 6 may be mounted in the upper chamber 3 in either the vertical direction or the horizontal direction, but when the upper door 11 is opened, the surface of the main board 6 on which electronic components are mounted can be easily seen. You should be able to do it. Further, the installation location of the main substrate 6 may be any of the ceiling surface, bottom surface, left side surface, right side surface, and back side surface of the upper chamber 3. In the present embodiment, the main board 6 is vertically mounted on the back side as shown in FIG. Further, the main substrate 6 is covered with a transparent or translucent main substrate case, so that both sides or one side of the main substrate 6 can be seen through without opening.

  The power supply box 8 incorporates a transformer, a constant voltage circuit, etc., and receives power from an external power supply to drive each part of the slot machine, for example, the main board 6, the reel unit 10, the hopper device, and various display parts. Power is supplied to each of the display circuits etc. with a specified voltage.

  Various devices 20 such as an accessory, a display device, an acoustic device, and / or a sub-board box may be attached to the back side surface of the upper door 11 as indicated by a dotted line in FIG. The arrangement of the main board 6 is preferably on the back side of the apparatus 20, which makes effective use of space. To keep costs down, the device 20 may not have a display device. At the very least, it is often the case that an accessory is installed. In this case, because of the opening / closing of the upper door 11, the business trip part may not contact the housing 2 and close on the trajectory of the rotation of the device 20, so the device may be attached only in a small space range. Therefore, instead of this, the apparatus 20 may be mounted inside the upper chamber 3 as shown in FIGS. In this case, the space can be effectively utilized by storing in the upper chamber 3. Moreover, the design change and exchange of the upper door 11 become easy.

  The apparatus 20 is preferably installed on the partition plate 5 from the viewpoint of installation stability and the like. Further, it is preferable that a display device or an accessory such as a liquid crystal display device is disposed close to the upper door 11. Therefore, it is preferable to provide a window on the upper door 11.

  As shown in FIG. 2, in this embodiment, the upper door 11 has a right-open structure, but as shown in FIG. 7, it may have a lower-open structure. In FIG. 7, the part numbers in FIG. The lower end concave edge of the upper door 11 is overlapped on the rear surface of the upper end convex edge 12a of the lower door 12, has an uneven fitting structure, and cannot be opened by the upper door 11 alone. That is, the upper door 11 cannot be opened unless the lower door 12 is opened.

  Moreover, although the upper door 11 is a hinged door structure connected to the housing 2 with a hinge, the upper door 11 may be fixed to the housing 2 by stopping with a fastening part such as a screw. In this case, the upper door 11 can be removed from the housing 2 by releasing the fastening component.

  Although the key cylinder lock 14 is necessary for the lower door 12, the key cylinder lock 13 may be omitted from the upper door 11 and may be fastened by a fastening part such as a screw from the outside or inside. This is because the frequency of opening the upper door 11 is less than that of the lower door 12. The upper door 11 may have a horizontal slide or vertical slide structure. It is also possible to open the upper door 11 with a setting key.

  In the present embodiment, when the lower door 12 is opened, a structure that automatically opens the upper door 11 with an operation unit (not shown) such as a lever is not provided. This is because the structure is simplified and the opening of the upper door 11 is forcibly blocked by the key cylinder lock 13 which is a closing portion. However, in order to improve operability, such an operation unit may be additionally provided.

Then, the three reels start to rotate at the same time, and the player can stop the corresponding reels by operating the stop buttons in order at an arbitrary timing. However, since the winning type or loss is already determined by electronic lottery, the reel stop control is started by operating the stop button, but basically the reel stop is reflected so that the result of electronic lottery is reflected. Control is performed. Then, when winning, the number of medals corresponding to the winning type is paid out to the medal tray 17.

  Next, when inspecting / repairing the swivel-type gaming machine 1, the lock 14 is first unlocked with the dedicated key, and the lower door 12 is opened. At this time, the inside of the lower chamber 4 is inspected and repaired as necessary.
