JP 2004-65493 A

It has been newly found that the power supply device 6 may be illegally operated by foreign objects in addition to the front switches. That is, as described above, there are a plurality of connectors 13a and 13b on the upper surface of the power supply device 6, and the connector terminals 14a and 14b of the electrical components are connected to the connectors 13a and 13b, but the periphery of the connectors 13a and 13b If a conductive foreign object is inserted into the substrate and the substrate is short-circuited, for example, the medal discharge device 5 can be malfunctioned to obtain a large number of medals. Further, since the hit probability is set by the ON / OFF signal for the main board, there is a possibility that the hit probability is changed illegally.
The present invention has been made in view of the above, and an object of the present invention is to provide a power supply device for a gaming machine that is resistant to unauthorized manipulation by a foreign object.

  In a power supply device of a gaming machine having a connector on an upper surface of a case body, the peripheral wall surrounds the connector with a peripheral wall higher than a protruding height of the connector terminal in a state where a connector terminal of another electrical component is inserted into the connector. A power supply device for a gaming machine is provided in which the upper surface of the connector terminal is closed with a top plate and the cable of the connector terminal is pulled out sideways from a cable port formed in the peripheral wall.

  Since the area around the connector and connector terminal of the power supply unit is covered with the peripheral wall and the top plate, foreign matter cannot contact the connector, and the foreign object entered the cable port formed on the peripheral wall and successfully contacted the connector terminal. However, in order to pierce the gap around the connector, it is necessary to insert the foreign substance vertically into the gap, and the direction (movement) of the foreign substance is restricted to the side when passing through the cable port opened sideways. Therefore, it is difficult to pierce the gap. Therefore, it is possible to completely block unauthorized work aimed at the upper surface of the power supply device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, taking a slot machine as an example. 1 is a perspective view of the power supply device, FIG. 2 is a longitudinal sectional view of the main part showing the usage state, FIG. 3 is a longitudinal sectional view of the main part showing the usage state, and FIG. 4 is an exploded perspective view of the power supply device. 5 is an exploded perspective view showing the upper part of the power supply device, FIG. 6 is an exploded perspective view of the power supply device, FIG. 7 is a longitudinal sectional view of the main part showing the use state of another embodiment, and FIG. It is the front view of the slot machine which was.

  As shown in FIG. 8, the slot machine has a door-type front panel 2 attached to the front surface of the outer frame 1 so that it can be opened and closed with the left side as a fulcrum. The outer frame 1 is formed in a box shape by a bottom plate 1a, a left side plate 1b, a right side plate 1c, a frame top plate 1d, and a back plate 1e, and a power supply device 6 is placed on the bottom plate 1a near the wall of the left side plate 1b. Installed. The power supply device 6 releases a variable display device 3 that rotates a plurality of (for example, three) drums 3a, 3b, and 3c to change the symbols that can be seen from the display window 4 of the front panel 2, and a medal that is a game medium. This is for supplying electric power to various electric components such as the medal discharge device 5 or a main board (not shown) for game control.

As shown in FIG. 4, the power supply device 6 is covered with a metal square case body 7. On the front surface of the case body 7, for example, a power switch 8, an error release switch 9, and a dedicated key for changing probability settings. Collected are switches such as a key switch 10 for setting a hit rate, a stop switch 11 and a settlement changeover switch 12 which are operated in the above.
On the other hand, a plurality of connectors 13a, 13b, and 13c for inserting connector terminals 14a, 14b, and 14c at the ends of cables 14 of other electrical components are provided on the upper surface of the case body 7 of the power supply device 6. In FIG. 4, one connector terminal 14 c is connected to an external power source and is used to supply power from the outside to the power supply device 6.

  Thus, the power supply device 6 of the present invention has the connector terminals 14a, 14b, 14c of other electrical components inserted into the connectors 13a, 13b, 13c on the upper surface of the case body 7, and the projection of the connector terminals 14a, 14b, 14c. The peripheral wall 15 higher than the height surrounds the connectors 13a, 13b, and 13c, and the upper surface of the peripheral wall 15 is covered with the top plate 16. Further, the cable ports 17a, 17b, and 17c formed in the peripheral wall 15 The cable 14 of the connector terminals 14a and 14b is pulled out sideways. Further, the power supply device 6 is provided with a front cover 18 on the front surface provided with switches, and the front cover 18 prevents the switches from being operated freely.

  The peripheral wall 15 and the top plate 16 are formed as a cap unit 19 made of synthetic resin, and the cap unit 19 is fixed to the upper surface of the case body 7 of the power supply device 6. The cap unit 19 divides one wide space by peripheral walls 15, 15... For each connector 13 a, 13 b, 13 c to make each room independent, and a portion corresponding to the heat exhaust hole 20 on the upper surface of the case body 7 is an exhaust heat chamber. 21. The exhaust heat chamber 21 communicates with an exhaust port 22 provided on the back plate 1 e of the outer frame 1, and the exhaust heat of the power supply device 6 is exhausted from the exhaust port 22 to the back of the machine through the exhaust heat chamber 21. Is done.

  As described above, the cable ports 17a, 17b, and 17c through which the cable 14 is passed are formed in the peripheral wall 15 of the cap unit 19, but the cable port 17c corresponding to the connector 13c at the wall extends to the top plate 16. This is because a space for inserting the cable 14 cannot be secured between the left side plate 1 b of the outer frame 1 and the peripheral wall 15. Therefore, in the power supply device 6 of the embodiment, among the connectors 13a, 13b, and 13c on the upper surface, the power supply connector 13c is disposed near the wall, and the other connectors 13a and 13b are disposed on the opposite side. By doing so, even if a foreign object is inserted from the cable port 17c vacated in the top plate 16, there is almost no harm as long as it is the connector 13c for supplying power.

  As shown in FIG. 5, fixing pieces 23, 23 bent in an L shape project from the bottom surface of the cap unit 19, and the fixing pieces 23, 23 are received by receiving holes 25, 25 on the upper surface of the case body 7. The cap unit 19 rests on the upper surface of the power supply device 6 when it is hooked. The cap unit 19 has a plate-shaped flange piece 24 projecting forward.

  On the other hand, as shown in FIG. 6, the front cover 18 that covers the front surface of the power supply device 6 has a main plate 18a that is substantially the same shape as the front surface of the case body 7, and side pieces 18b that protrude from both edges on the back side of the main plate 18a. , 18b and a top piece 18c protruding from the top of the back side of the main plate 18a. As shown in FIG. 6, fastening pieces 23, 23... Having the same form as the cap unit 19 are projected from the front cover 18, and the fastening pieces 23, 23. The front cover 18 can be attached to the front surface of the power supply device 6 by being hooked in 25, 25. A long hole 26 corresponding to the error release switch 9 on the front surface of the case body 7 is formed in the main plate 18 a of the front cover 18, and the error release switch 9 faces the outside from the long hole 26. The space 27 between the main plate 18a and the case body 7 and the long hole 26 are partitioned by a sleeve 28 projecting along the inner periphery of the long hole 26. There is no possibility of reaching the switches on the front surface of the case body 7.

  The cap unit 19 and the front cover 18 are firmly attached to the case body 7 by a commercially available button-type panel fastener 29 (trade name “Nylatch”: registered trademark). That is, as shown in FIG. 4, the case body 7 is provided with a through hole 30 through which the shaft portion 29 a of the button-type panel fastener 29 is passed in the front corner portion of the upper surface, and the cap unit 19. A U-shaped notch 31 corresponding to the through hole 30 is formed in the collar piece 24, and a stopper hole 32 corresponding to the through hole 30 is provided in the top piece 18 c of the front cover 18. ing. Then, the top piece 18c of the front cover 18 is overlaid on the flange piece 24 of the cap unit 19, and the shaft portion 29a of the button type panel fastener 29 is directed from the stop hole 32 of the top piece 18c toward the through hole 30 of the case body 7. When the lock button 29b of the button-type panel fastener 29 is finally pushed in, the shaft portion 29a expands and the button-type panel fastener 29 cannot be removed from the through hole 30 as is well known. In this state, the front cover 18 is locked by the button-type panel fastener 29, and the cap unit 19 is in a state in which the flange 24 on the front edge is under the top piece 18c of the front cover 18, It is fastened with a button-type panel fastener 29 via the front cover 18.

Further, the cap unit 19 and the front cover 18 are locked with a lock 33 as required. That is, as shown in FIGS. 2 and 4, a fixing plate 35 having a hole 34 is provided in the middle of the upper front edge of the case body 7, and the fixing is performed on the upper surface of the top piece 18 c of the cap unit 19. A lock plate 37 with a hole 36 that fits the plate 35 is protruded, and the lock plate 37 and the fixing plate 35 are overlapped in the front-rear direction, and both holes 34 and 36 are locked through a lock bar 33a of the lock 33. Of course, the cap unit 19 cannot be removed because the front cover 18 cannot be removed when the lock 33 is engaged.
A concave space 38 is formed at the front center of the cap unit 19, and the lock 33 is accommodated in the space 38. Whether or not to lock the lock 33 is up to the user, so the lock 33 may be used only when necessary.

  In the first embodiment, the cap unit 19 is fixed to the upper surface of the case body 7 to form the peripheral wall 15 and the top plate 16. However, although not shown, the metal peripheral wall 15 extends to the upper part of the case body 7. However, a synthetic resin top plate 16 may be placed on the peripheral wall 15.

  In the first embodiment, the long hole 26 for passing the error release switch 9 is formed in the front cover 18, but a similar opening (not shown) is formed corresponding to the key switch 10 for setting the hit rate. May be. By doing so, the hit rate setting operation can be performed efficiently. Of course, since a dedicated key is required for the operation of the key switch 10, there is no problem in principle even if the key switch 10 is exposed in front of the front cover 18.

However, since the key switch 10 used for the power supply device 6 has a relatively low crime prevention level, it may be forged, and in such a case, an unauthorized operation using the forged key can be performed.
In view of this point, as shown in FIG. 7, an opening 39 may be provided in the front cover 18, and an intermediate lock 40 may be incorporated between the opening 39 and the key switch 10. The intermediary lock 40 is composed of a lock body 40a and a dedicated key 40b of the key switch 10. The dedicated key 40b is fixed to the rear end of the lock body 40a, and a key is inserted into a key hole (not shown) of the lock body 40a. The dedicated key 40b can be turned only when it is inserted. The intermediate lock 40 is in a non-rotatable and axially slidable state in a receiving tube 41 provided in the opening 39 portion of the front cover 18 (for example, the receiving tube 41 and the lock body 40a are non-cylindrical, such as a hexagonal column shape). And is biased toward the key switch 10 by an elastic body 42 provided in the receiving cylinder 41 (the elastic body 42 in FIG. 7 is a dishwasher-like spring). The elastic body 42 functions to securely insert the dedicated key 40b of the intermediate lock 40 into the key switch 10. However, if the key is turned while pressing the intermediate lock 40, the elastic body 42 is essential. Not.

  If the intermediate lock 40 is incorporated between the opening 39 of the front cover 18 and the key switch 10 as described above, a unique key that matches the intermediate lock 40 is required to operate the key switch 10, and Since the intermediate lock 40 having a high crime prevention level can be used, it is possible to satisfy both the operability and the crime prevention when changing the probability setting described above.

  As mentioned above, although this invention was demonstrated about Embodiment and Examples 1 thru | or 3, of course, this invention is not limited to the said embodiment etc. For example, in the first embodiment, all the connectors 13a, 13b, and 13c are handled by one cap unit 19, but the peripheral wall 15 and the top plate 16 may be individually provided for each connector 13a, 13b, and 13c. However, if one cap unit 19 is made to correspond to all the connectors 13a, 13b, and 13c as in the first embodiment, it goes without saying that workability is improved, and the exhaust heat chamber 21 is also provided by using the partition of the peripheral wall 15. Therefore, it can be used as a countermeasure for temperature rise inside the slot machine.

  In the embodiments and the like, a slot machine is exemplified as a gaming machine, but the present invention can also be applied to gaming machines other than the slot machine.
