[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the configuration of the game board 1 of the gaming machine to which the storage case 20 according to the embodiment is applied will be described with reference to FIG. FIG. 5 is a rear view of the gaming board 1. In the drawing, a winning ball set cover 2 that covers a main area of the game board 1 is detachably attached to a back surface of the game board 1 formed in a substantially square shape by a set cover fixing member 4. A prize device cover 3 that covers the rear of a center prize device (not shown) provided at the center of the game board 1 is attached to the center of the prize ball collecting cover 2, and a side of the prize device cover 3. On the other hand, a storage case 20 constituting a main part of the present embodiment is arranged. The prize winning device cover 3 is generally formed such that the center prize device is largely protruded rearward of the game board 1 and is greatly swelled rearward so as to cover the protruding portion. At the upper center of the game board 1, a relay terminal plate 5 for temporarily connecting wiring of electric components such as switches, display lamps, and solenoids provided on the game board 1 is fixed. Then, wiring is connected from the relay terminal plate 5 to a control circuit board 22 described later housed in the housing case 20, thereby electrically connecting the electric components and the control circuit board 22 to control them. It has become.
[0007]
By the way, as shown in FIG. 4, a window opening 6 having a substantially square shape is opened in the winning ball collecting cover 2, and a reinforcing rib 7 is provided upright on the rear edge of the window opening 6. The window opening 6 is opened to allow the center prize device to penetrate backward, and most of the window opening 6 is covered by the prize device cover 3. For this reason, a cover mounting boss 8 for fixing the winning device cover 3 with a screw (not shown) is planted in the outer even corner portion of the window opening 6. Further, a reinforcing rib is provided upright on one side of the window opening 6 on the back surface of the winning ball collecting cover 2, and a board case mounting boss 9 is formed on the reinforcing rib. The board case mounting boss 9 fixes a support member 10 that supports the storage case 20 so as to be openable and closable. That is, the storage case 20 is rotatably supported by inserting the support shafts 12 formed above and below the fixing member 11 fixed to one side piece into the bearing portion of the support member 10. ing. Then, the storage case 20 is supported by the winning ball set cover 2 by locking a fixing piece 31 described below formed above and below the storage case 20 and a locking member 14 formed above and below the support member 10. It has become. Further, when replacing the control circuit board 22 with the exchange of the game board, after releasing the locked state by the locking member 14 , the storage case 20 is turned toward the winning device cover 3 and lifted upward. Thus, the support shaft 12 can be removed from the bearing portion and easily replaced. In addition, the side surface of the winning device cover 3 on the storage case 20 side is a cutout portion 13 which is cut out so that the storage case 20 can be rotated to a substantially right angle direction.
[0008]
The structure of the storage case 20 attached to the back of the game board 1 as described above will be described below with reference to FIGS. 1 is a cross-sectional view of the storage case 20 cut in the vertical direction, FIG. 2 is a cross-sectional view of the storage case 20 cut in the horizontal direction, and FIG. 3 is an exploded perspective view of the storage case 20. In the figure, a storage case 20 includes a fixed case 21 for fixing a control circuit board 22 and a cover case 23 for covering the fixed case 21. The fixed case 21 and the cover case 23 are both formed by pressing a steel plate material that is a conductive material. Therefore, each configuration will be described in detail below.
[0009]
First, as shown in FIG. 3, the fixed case 21 has side plates 26 erected on three sides of the flat bottom plate 25, which is formed in a substantially rectangular shape except the lower edge from the periphery thereof, and the bottom plate 25 has a rectangular substrate. An opening 24 constituting the back surface observation means is provided. The opening 24 is formed to have a size such that substantially the entire area of a later-described solder surface 38 of the control circuit board 22 can be seen through, but smaller than the size of an opening 40 to be described later formed in the cover case 23. . This is because, as described later in detail, it is sufficient to determine whether or not a jumper wire is connected to the solder surface 38, and in this sense, a very large opening is not required.
[0010]
An engagement piece 27 extends from an upper edge of the side plate 26 at an appropriate position. The engaging piece 27 is a portion that overlaps with the side plate portion 42 of the cover case 23. The fixed portion 21 and the cover case 23 are integrally formed by fastening the overlapped portion together with a screw. Has become. 1 and 2, the engaging piece 27 is formed so as to be inside by the thickness of the cover case 23, so that the fixed case 21 is overlapped with the cover case 23. The side plate portion 26 of the cover case 23 and the side plate portion 42 of the cover case 23 are flush with each other, and a seal paper (not shown) is attached to the connection portion. Further, the left and right side plate portions 26 are formed with heat release holes 28 for releasing heat generated from an electronic component 37 described later to the outside. The heat release hole 28 is formed at a position (part corresponding to a surface space 51 described later) above a component surface 36 described later when the control circuit board 22 is attached to the fixed case 21. This is because most of the heat generated from the control circuit board 22 comes from the electronic components 37 provided on the component surface 36 and almost no heat is generated from the solder surface 38 side.
[0011]
A plurality of cutout openings 29 are formed in a bent portion between the bottom plate portion 25 and the left and right side plate portions 26, that is, in a peripheral edge serving as a base portion of the storage case 20. As shown in FIG. 2, the cutout opening 29 allows a rear space 50 formed by the solder surface 38 of the control circuit board 22 and the bottom plate 25 to be seen through, and is connected to the solder surface 38 and hangs down. The purpose is to find jumper wires. Therefore, the cutout position, size, number, and the like of the cutout openings 29 may be provided in any manner as long as the whole area of the back space 50 can be seen through.
[0012]
A board fixing pin 30 for fixing the control circuit board 22 to the bottom plate 25 of the fixing case 21 with a screw 39 is provided at an even angle portion thereof. The board fixing pins 30 are caulked so as to penetrate the bottom plate 25, and form a back space 50 between the solder surface 38 and the bottom plate 25 with the control circuit board 22 fixed thereto, and A surface space 51 is formed between the cover 36 and the front plate portion 41 of the cover case 23. Further, as described above, the fixing pieces 31 for locking with the locking members 14 for fixing the storage case 20 extend above and below the bottom plate portion 25.
[0013]
Further, inside the opening 24 formed in the bottom plate portion 25, a transparent plate 32 made of a synthetic resin constituting a substrate back surface observation means is provided so as to close the opening 24. On the side of the transparent plate 32 facing the control circuit board 22, a connection recess 33 into which the tip of a connection member 34 (see FIGS. 1 and 2) fixed to the solder surface 38 of the control circuit board 22 is inserted. A plurality is formed. This connecting member 34 is also desirably formed of a transparent material. When the control circuit board 22 is fixed to the board fixing pins 30 with screws 39, the transparent plate 32 automatically closes the opening 24. Then, since the solder surface 38 of the control circuit board 22 can be seen through the transparent plate 32, when a jumper wire is connected to the solder surface 38, it can be easily found. The reason why the transparent plate 32 is closed from the inside of the opening 24 is as follows. That is, when the transparent plate 32 is closed from the outside of the opening 24, the transparent plate 32 is broken, a fraudulent act of connecting a jumper wire to the solder surface 38 is performed, and then the transparent plate 32 formed in the same manner as the transparent plate 32 is formed. Can be performed so as to close the opening 24, but by closing the transparent plate 32 from the inside, even if the transparent plate 32 is destroyed and the wrongdoing is performed in the game hall, the transparent plate 32 Can not be closed from the inside, and fraudulent acts can be easily found.
[0014]
In the illustrated embodiment, the back space 50 can be viewed through either the cutout opening 29 or the transparent plate 32, but only one of them is sufficient. That is, when the cutout opening 29 is formed, the opening 24 does not need to be formed, and therefore the transparent plate 32 is not required. When the opening 24 is formed and closed by the transparent plate 32, the cutout opening 29 is not required. Of course, both may be provided as in the embodiment.
[0015]
On the other hand, a conductive plate member 35 is detachably attached to the outside of the opening 24 of the bottom plate portion 25 by a screw. In this case, as the conductive plate member 35, a steel plate punched out to form the opening 40 of the cover case 23 formed to be larger than the opening 24 can be used as it is. For this reason, there is an advantage that it is not necessary to specially process and prepare the conductive plate member. The reason why the outside of the opening 24 is covered with the conductive plate member 35 in this manner is as follows. That is, the bottom plate portion 25 of the storage case 20 is located at a position facing the winning ball collecting cover 2 as described above. For this reason, the bottom plate portion 25 is affected by an electricity-stagnant material such as a winning ball flowing down inside the winning ball collecting cover 2. The static electricity may be charged on the winning ball collecting cover 2, and the noise generated when the charged static electricity is discharged may cause a malfunction of the control circuit of the control circuit board 22. Thus, if the opening 24 of the bottom plate portion 25 is kept covered with the transparent plate 32 made of synthetic resin, it is highly likely to be directly affected by noise, and the shielding effect of the storage case 20 is extremely reduced. It becomes. In order to prevent this, the opening 24 is closed by the conductive plate member 35 to improve the shielding effect of the storage case 20. In addition, instead of using the steel plate punched out to form the above-described opening 40 as the conductive plate member 35, for example, a conductive sheet attached or attached to the bottom plate portion 25 or the transparent plate 32 may be used, A material obtained by applying a conductive paint to a non-conductive material may be used.
[0016]
However, if the outside of the opening 24 is covered with the conductive plate member 35, the solder surface 38 of the control circuit board 22 cannot be seen through the transparent plate 32. The conductive plate member 35 may be removed by loosening the screw fixing the plate member 35. The conductive plate member 35 may be detachably disposed outside the opening 24, and a locking member for locking the conductive plate member 35 instead of a screw is formed on the back side surface of the bottom plate 25. Is also good. Alternatively, the conductive plate member 35 is fixed to the support member 10 that supports the storage case 20, and the opening 24 is closed by the conductive member 35 when the storage case 20 is closed and locked by the locking member 14. You may be comprised so that it may be.
[0017]
Also in the cover case 23 that covers the fixed case 21 described above, as shown in FIG. 3, the side plate portion 42 is erected from the periphery of the substantially rectangular flat plate-shaped front plate portion 41 toward the rear, and An opening 40 constituting a rectangular substrate surface observation means is opened in the plate portion 41. The opening 40 is formed in such a size that substantially the entire area of a component surface 36 of the control circuit board 22 described later can be seen through. This is to determine whether the electronic component 37 mounted on the component surface 36 is different from the specified one, and is formed larger than the opening 24. A positioning piece 43 is extended at an appropriate position of the side plate portion 42 and engages with a positioning portion formed on the fixed case 21 to determine an accurate position of the fixed case 21 and the cover case 23. ing. The side plate 42 on one side (right side in FIG. 3) is shortly erected, and forms a rectangular wiring lead-out opening 44 (see FIG. 1) when combined with the fixed case 21. It has become. The wiring for connecting the control circuit board 22 and the relay terminal board 5 is drawn out from the wiring lead-out opening 44.
[0018]
A connection hole 45 is formed in the front plate portion 41 along the periphery of the opening 40. The transparent plate 47 is firmly fixed to the cover case 23 by inserting and welding a connecting projection 49 of a transparent plate 47 described later into the connecting hole 45. Further, a heat release hole 46 is formed in the left and right side plate portions 42.
[0019]
Further, a transparent plate 47 made of a synthetic resin constituting a substrate surface observation means is provided inside the opening 40 formed in the front plate portion 41 so as to close the opening 40. The transparent plate 47 has heat release holes 48 formed in the upper and lower portions thereof, and has connection projections 49 projecting from the periphery thereof. The connection protrusion 49 is for preventing the transparent plate 47 from falling off by welding a portion protruding from the connection hole 45 after being inserted into the connection hole 45. The reason for providing the transparent plate 47 from the inside of the opening 40 is the same as the reason for providing the transparent plate 32 from the inside of the opening 24.
[0020]
The configuration of the storage case 20 according to the embodiment has been described above. In the storage case 20, the component surface 36 of the control circuit board 22 on which the electronic components 37 are mounted and the solder surface 38 on the opposite side are opposed. Openings 40 and 24 are formed in the front plate portion 41 and the bottom plate portion 25 of the storage case 20 so that the entirety of the control circuit board 22 can be seen through, and the openings 40 and 24 are formed by the transparent plates 47 and 32. Since it is closed, the component surface 36 and the solder surface 38 of the control circuit board 22 can be seen through the transparent plates 47 and 32. Therefore, the electronic components 37 mounted on the component surface 36 are defined. It can be easily found whether or not it is different from the one, and whether or not a jumper wire is connected to the solder surface 38 can be easily found. Further, since the front plate portion 41 and the bottom plate portion 25 of the storage case 20 are closed by the transparent plates 47 and 32, the shielding effect against external noise is reduced accordingly, but at least the opening of the bottom plate portion 25 which is in contact with the pachinko machine side. Since the conductive plate member 35 is removably disposed outside the motor 24, noise countermeasures due to static electricity or the like generated on the pachinko machine side can be taken. Further, instead of forming the opening 24 in the bottom plate 25, the back space 50 formed by the bottom plate 25 of the storage case 20 and the solder surface 38 of the control circuit board 22 can be seen through the periphery of the base of the storage case 20. Even when the notch opening 29 is formed, the space below the solder surface 38 of the control circuit board 22 can be seen through the notch opening 29, so that it is easy to determine whether or not a jumper wire is connected to the solder surface 38. Can be found. In this case, since there is no need to open the opening 24 in the bottom plate 25 of the storage case 20 and there is the bottom plate 25 formed of a conductive material as it is, bother the conductive plate member 35 to the bottom plate 25. The shielding effect can be maintained even if it is not detachably arranged.
[0021]
【The invention's effect】
As is clear from the above description, in the present invention, the component surface of the control circuit board can be seen through the board surface observation means, and the solder surface of the control circuit board can be seen through the board back surface observation means. Therefore, it can be easily found whether or not the electronic component mounted on the component surface is different from the specified one. Further , since the conductive member is disposed between the support member attached to the back surface of the gaming machine and the substrate back surface observation means, the shielding effect can be maintained. Further, since the conductive member is provided on the support member side of the back of the gaming machine, the conductive member and the substrate back surface observation means can be separated by rotating the storage case with respect to the support member, The work of checking the solder surface becomes easy.
