Description

The present invention, pachinko machine or the like gaming machine, in particular relates to improved gaming machine fraud prevention structure.

For pachinko machines and pachislot machines, the inner frame on which the mechanical parts are mounted is attached to the outer frame and fixed to the mounting base in the game hall (hall) via this outer frame. While the frame is fixed, the inner frame is rotated with the hinge portion as a fulcrum and is pulled out to expose the parts to be installed on the back side of the inner frame.
Conventionally, the outer frame of this kind of gaming machine is generally a wooden outer frame in which wooden boards are assembled in a rectangular shape, but synthetic resin is used because of problems such as difficulty in obtaining materials, manufacturing cost, and product accuracy. An outer frame made of aluminum and an outer frame made of aluminum alloy are provided and put into practical use.

The outer frame made of synthetic resin or aluminum alloy can be molded integrally with a molding machine, so it can provide considerable accuracy with the mold and exhibits characteristics not found in wood. For the frame, a material-saving structure is usually selected from the viewpoint of saving material and reducing the weight, with the limit of the strength that can support the inner frame.
On the other hand, in order to prevent fraudulent acts on the mechanical parts of the inner frame to be installed on the outer frame, such as illegal release of prize balls due to the insertion of a piano wire, the summing part with the inner frame, that is, the inner frame is closed. Usually, a barrier is provided in a gap between the outer frame and the outer frame so that a piano wire or the like cannot enter from the gap between the inner and outer frames when the gaming machine is used.

Providing this barrier is common in this type of gaming machine from the viewpoint of preventing fraud, and there is no particular example, but for example, the one described in Patent Document 1 and materials are synthesized. Examples of the resin include those described in Patent Document 2.
JP2003-340079A. JP-A-8-276057.

The one described in Patent Document 1 fixes an upper surface cover 23 on the upper surface of the curtain plate body 21 in order to close the gap in the summing portion between the curtain plate body 21 of the outer frame 10 and the front frame 30 which is the inner frame. The vertical wall 23b to be erected from now on, that is, the path of an unauthorized instrument inserted from the front side by a barrier is changed to prevent an illegal act.
Further, the one described in Patent Document 2 is made of a synthetic resin for the inner and outer frames. Here, a receiving concave groove 51 that opens forward is formed in the front joint portion of the outer frame 4, and the rear surface of the inner frame 3 is formed. When a metal plate 55a, 55b, 55c, 55d is provided on the side and the inner frame is closed, this metal plate is fitted into the receiving groove 51 of the outer frame 4 to fill the gap between the two frames to prevent crime. It is structured.

In this way, as a means for preventing illegal acts that have conventionally been performed through the gap between the outer frame and the inner frame, a folded portion is formed at the summing portion of both frames to prevent the straight intrusion of illegal instruments such as piano wires. The structure is adopted, and each has a predetermined effect, but the formation of the bent portion is not the same depending on the material forming the outer frame, and different correspondence is required Become.
That is, in the case of Patent Document 1, since the outer frame 10 is made of wood, the top cover 23 formed separately is fixed with the screw 24, and in the case of Patent Document 2, the outer frame 4 is made of synthetic resin. Therefore, the receiving recess 51 formed in the front joining portion (summing portion) can be formed to open forward.

  However, when the material of the outer frame is an aluminum alloy, it is impossible to adopt the same structure as the outer frame made of the above-mentioned wood even if it can be integrally formed by die casting of aluminum. Even if the same integral molding method is adopted, making the same structure as the outer frame made of a synthetic resin is not necessarily preferable from the viewpoint of not only making the structure complicated but also effectively utilizing the material.

In view of the above-described conventional circumstances, the present invention incorporates a structural reinforcing means into an anti-fraud means while taking advantage of the excellent formability of an aluminum alloy, particularly in the outer frame of a gaming machine formed from an aluminum alloy. It is an object of the present invention to provide a gaming machine in which an aluminum alloy having an appropriate outer frame is formed from a material while making both the above compatible.
When using an aluminum alloy as a material, it is natural to reduce the thickness of the structure as much as possible from the viewpoint of saving material, and make up for this by placing reinforcing ribs at key points, thereby ensuring its strength. However, the present invention intends to provide a gaming machine having a fraud prevention wall with higher accuracy by utilizing the reinforcing rib as a security barrier.

In order to achieve the above object, the present invention is an outer frame formed of an aluminum alloy material, and a lower frame plate is horizontally mounted between left and right vertical frames forming a rectangular outer frame main body portion. The inside of the frame main body is partitioned into an upper inner frame storage frame portion and a lower front decorative plate mounting frame portion. On the other hand, the upper horizontal frame, the left and right vertical frames, and the lower frame constituting the inner frame storage frame portion Reinforcing ribs projecting inwardly on the respective inner side surfaces of the frame plate are provided over the entire length, and the ends of the reinforcing ribs struggling at each corner portion of the inner frame storage frame portion This is because an annular fraud prevention wall is constructed which is integrally connected and continuous along the inner surface.
The present invention thereby increases the strength of the outer frame main body portion, and at the same time, surrounds the peripheral edge portion of the inner frame confined in the inner frame storage frame portion by the fraud prevention wall, and closes the gap formed between the inner and outer frames, thereby illegal equipment It is to prevent the intrusion of.

The outer frame main body portion increases the strength of the outer frame main body portion itself by forming the front decorative plate mounting frame portion at the lower portion, and at the same time, the upper horizontal frame forming the upper inner frame storage frame portion and the left and right frames. Sufficient strength can be ensured by integrally projecting inward reinforcing ribs over the entire length of each of the inner surfaces of the vertical frame and the lower frame plate.
Therefore, the formation of the reinforcing ribs can reduce the thickness of each frame part and reduce the weight, and an annular fraud prevention wall is constructed in the inner frame storage frame part by the continuous reinforcement ribs. By abutting and surrounding the peripheral edge of the inner frame confined from the front side, illegal acts performed through the gap between the inner and outer frames are effectively prevented.

Furthermore, the present invention relates to the inner frame storage frame portion, while the upper horizontal frame and the left and right vertical frames and the lower frame plate constituting the inner frame storage frame portion align their front edge portions on the same plane, Reinforcement ribs are erected from the middle of the depth width in the left and right vertical frames, and from the front edge of the upper horizontal frame and lower frame plate, and reinforced at each corner of the inner frame storage frame. A game characterized by constructing a continuous annular fraud prevention wall by connecting the ends of the ribs together at the connecting portion, and surrounding the peripheral edge of the inner frame by this fraud prevention wall to prevent the intrusion of fraudulent instruments Is to provide a machine .

In addition, the present invention provides a hinge receiving portion in which upper left and right vertical frames constituting the inner frame storage frame portion of the outer frame, left and right vertical frames, and a lower frame plate are pivotally attached with hinge portions provided at the upper and lower left ends of the inner frame. Are integrally formed so as to be opposed to each other in the vertical direction, and the reinforcing rib in the lower frame plate is integrally connected by retracting the left end adjacent to the hinge receiving portion to the position of the reinforcing rib formed in the left vertical frame, It is an object of the present invention to provide a gaming machine characterized in that a rotation area of an inner frame is formed in front of the connecting portion.

  By the way, the reinforcing ribs formed on the inner frame storage frame portion have a purpose of reinforcing each frame portion and the purpose of preventing fraud. It will be. As the selection, for example, in order to prevent fraudulent acts caused by a piano wire or the like, a selection is made such that the wall thickness is reduced and the protrusion is formed in a high protruding state so that the invasion path of the piano wire or the like is greatly refracted.

  The reinforcing ribs are formed so as to protrude inward from the inner surface of the upper horizontal frame, the left and right vertical frames, and the lower frame plate of the inner frame storage frame portion. When receiving the back of the peripheral edge of the inner frame that is closed from the front of the frame, receiving unauthorized equipment such as a piano wire entering from the front through the gap between the inner and outer frames, preventing linear intrusion, and when pressed further The tip is guided toward the inside of the rib, and bent at a right angle to prevent the rearward entry.

  In addition, this reinforcing rib has a structure that surrounds the inner periphery of the inner frame storage frame part and surrounds the entire periphery of the inner frame by surrounding the inner periphery of the inner frame storage frame part. Certain fraud prevention can be measured.

  Of course, the formation of the reinforcing rib can be integrally formed when the outer frame main body is molded, and the molding die is also complicated because the rib simply protrudes inward. There is no need to select a mold, and the productivity is excellent.

Accordingly, since the present invention is configured as described above, a lightweight outer frame that secures the required strength can be obtained while minimizing the amount of aluminum alloy material used, and at the same time, the piano An outer frame having fraud prevention means capable of effectively preventing fraudulent acts such as lines can be obtained.
Moreover, according to the present invention, the reinforcing rib, which is a reinforcing means required in accordance with the weight reduction, is also used as an improper means immediately, and the reinforcing rib is integrated with the molding of the outer frame main body. Since it can be formed, it does not require special attachment as in the case of being formed separately, and therefore can be provided without increasing the manufacturing cost.
