Description

  The present invention relates to a pachinko machine, and more particularly to a frame member provided in the pachinko machine and a structure of a door member supported by the frame member so as to be opened and closed.

In pachinko machines, gaps are formed between the frame member that fixes the game board and the door member that is supported by the frame member so that it can be opened and closed, or between the game board and the mechanism plate. There is a risk that a so-called goto action for intruding foreign matter such as the like will be performed.
Therefore, for example, in the pachinko machine described in Patent Document 1, a concave groove is provided on the back surface of the game board, and a blocking plate that is fitted to the concave groove is provided on the mechanism plate, thereby preventing the goto action. Proposed. Moreover, in the pachinko machine described in Patent Document 2, by attaching a fraud prevention piece formed of an elastic body to the frame member, and closing the gap with the frame member with the fraud prevention piece when the door member is closed, Proposals have been made for preventing goto acts.
Japanese Utility Model Publication No. 6-75573 (pages 6 to 8, FIGS. 4 and 5) JP 2004-275257 A (2nd to 4th pages, FIGS. 3 to 5)

However, in the pachinko machine described in Patent Document 1, the degree of entry of the blocking piece into the groove may be low due to manufacturing errors or the like. In such a case, if the blocking piece is forcibly inserted with a strong force, the game board or the mechanism plate is bent and the blocking piece is detached from the concave groove, thereby allowing a goto action.
On the other hand, in the pachinko machine described in Patent Document 2, since the entire tamper-proofing piece is formed of an elastic member, if a strong force is applied to the tamper-proofing piece by a piano wire or the like, the tamper-proofing piece is damaged. There is a problem that allows foreign objects such as piano wires to enter.

  Therefore, the present invention has been made to solve the above-described problems, and when a gotting action is performed, a strong force is applied to the gap between the frame member and the door member by a foreign object such as a piano wire. Even so, we propose a pachinko machine that can minimize the gaps that occur and that can more reliably prevent fraud.

In order to achieve the above object, a pachinko machine according to claim 1 is provided with at least one of a frame member and a door member, a storage recess having an opening opened toward the other, a storage recess and a storage recess. And an anti-tampering piece whose end is movably supported from the part toward the other, and the anti-tampering piece is biased toward the other by an elastic member.
As a result, the fraud prevention piece strokes the storage recess based on the biasing force from the elastic member, so that even if the door member or the frame member is bent during the goto action, the gap is kept to a minimum. It becomes possible to prevent intrusion of foreign matters such as piano wires.
In addition, since a fraud prevention piece for closing the gap apart from the elastic member is used as a dedicated member, it is not necessary to consider the presence or absence of elasticity when selecting the material etc., by selecting an appropriate material Even when a strong force is applied by a piano wire or the like, it is possible to prevent the fraud prevention piece from being damaged.
Further, since the tamper-proof piece is stored in the storage recess, even if the tamper-proof piece is supported and stroked stably and the door member is opened and closed many times, the whole tamper-proof piece is more elastic than the elastic member. Compared with the case where it becomes, it can prevent that the clearance gap between a frame member and a door member spreads.
Further, since the anti-tampering piece for closing the gap apart from the elastic member is used as a dedicated member, it is easy to make the anti-tampering piece longer stroke than the case where the whole is made of elastic member. Even if the member or the frame member is greatly distorted, it is possible to keep the gap to a minimum and prevent the entry of foreign matter such as a piano wire.

Further, the pachinko machine according to claim 2 is configured by dividing the fraud prevention piece into a plurality of pieces along the circumferential direction of the frame member, and one divided fraud prevention piece is independent of other adjacent fraud prevention pieces. And is slidably supported toward the door member and the frame member.
As a result, even if a wide range of gaps between the frame member and the door member is blocked with a fraud prevention piece, even if the frame member or the door member is bent, it follows the bent frame member or the door member. Thus, it becomes possible to close the gap step by step with a plurality of fraud prevention pieces. Accordingly, it is possible to prevent the entry of foreign matter such as a piano wire while keeping the gap to a minimum.

Furthermore, the pachinko machine according to claim 3 forms a convex portion on one adjacent fraud prevention piece among the divided fraud prevention pieces, and a concave portion that fits the convex portion on the other fraud prevention piece. The fraud prevention piece is formed by forming and fitting the concave portion and the convex portion, respectively.
Accordingly, it is possible to prevent foreign matters such as piano wires from entering through the gaps between the divided portions of the fraud prevention pieces.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment embodying a pachinko machine according to the present invention will be described in detail with reference to the drawings. First, a schematic configuration of the pachinko machine 1 according to the present embodiment will be described based on FIG. 1 and FIG.

Storage recesses 21A and 21B are formed in the inner frame 3 along the circumferential direction, and the storage recess 21A further includes six anti-tampering pieces 22A to 22F and a coil spring 23 that is an elastic member. In the storage recess 21B, the anti-fraud pieces 22G to 22I divided into three parts and the coil spring 23 as an elastic member are respectively stored (see FIGS. 3 to 5).
Further, a synthetic resin door member 7 is mounted on the front side of the upper half of the inner frame 3 so as to be freely opened and closed by being pivotally supported by the upper door hinge 8 and the lower door hinge 9 at the top and bottom of the left end edge. . In addition, a substantially circular window portion 10 is opened at a substantially central portion of the door member 7, and the game board game is played through two glasses mounted on a glass holding frame formed on the outer peripheral edge portion of the window portion 10. It is configured so that the area can be seen.

An upper plate 11 for receiving a prize ball to be paid out is disposed on a synthetic resin plate 12 below the door member 7. The plate 12 is pivotally supported at the top and bottom of the left edge, and is attached so that it can be opened by lowering a lever (not shown) provided inside after opening the door member 7. Further, an operation button 13A of a card-type ball lending machine, a card balance display device 13B, and the like are provided on the central front surface of the upper plate 11.
Further, a lower plate 14 is disposed under the upper plate 11. Further, the pachinko ball of the upper plate 11 is configured to be sent to a launching device (not shown) connected to the operation handle 15 via a ball feeding mechanism (not shown) communicating with the upper plate 11.

  A game board (not shown) is attached to a mechanism board (not shown) so that the game board (not shown) is detachable at a substantially central portion of the inner frame 3. A mechanism set board 20 made of synthetic resin and containing various substrates is attached to the back side of the mechanism board with a hinge so as to be opened and closed.

Next, the fraud prevention piece 22 and the coil spring 23 housed in the housing recess 21 of the inner frame 3 will be described. FIG. 3 is a front view showing the inner frame 3 with the door member 7 removed. 4 and 5 are cross-sectional views taken along line AA in FIG.
As shown in FIGS. 3 and 4, storage recesses 21 </ b> A and 21 </ b> B are formed in the inner frame 3 of the pachinko machine 1 according to the present embodiment along the circumferential direction. Here, the storage recess 21 </ b> A is formed from the right side to the upper side of the inner frame 3, and the storage recess 21 </ b> B is formed in a linear shape along the left side of the inner frame 3. Further, the resin-molded long fraud prevention pieces 22A to 22F are stored in the storage recess 21A in a state of being divided into three parts on the right side and the upper side, respectively. On the other hand, the resin-molded long fraud prevention pieces 22G to 22I are accommodated in a state of being divided into three parts.

  Further, two coil springs 23 are housed in a total of 18 positions corresponding to each fraud prevention piece between the fraud prevention pieces 22A to 22I and the housing recesses 21A and 21B. Then, as shown in FIG. 4, the coil spring 23 biases the fraud prevention pieces 22 </ b> A to 22 </ b> I toward the door member 7. As a result, as shown in FIG. 5, force is applied to the tamper-proofing pieces 22 </ b> A to 22 </ b> I from the direction of the door member 7, so that the tamper-proofing pieces 22 </ b> A to 22 </ b> I The end portion 27 of the tamper-proof piece moves toward the inner frame 3 along with the slide. Further, when the bias from the direction of the door member 7 is released, the tamper-proofing pieces 22A to 22I slide in the direction of the door member 7 along the side walls of the storage recesses 21A and 21B, and accordingly, the end portions 27 of the tamper-proofing pieces are moved. It moves toward the door member 7 from the opening 25.

  On the other hand, an engagement recess 26 is formed on the back side surface of the door member 7 (that is, the surface facing the inner frame 3) at a position corresponding to the storage recesses 21A and 21B. When the door member 7 is closed with respect to the inner frame 3, the end portion 27 of the fraud prevention piece urged by the coil spring 23 is accommodated in the engaging recess 26, so that the door member 7 and the inner frame 3 are accommodated. To prevent the intrusion of foreign objects such as piano wire.

  Similarly, a guide slope 28 is formed inside the engagement recess 26 on the back side surface of the door member 7. Here, the guide slope 28 is an inclined surface inclined to the engagement recess 26 at a predetermined angle (for example, 10 degrees), and the end 27 is closed when the door member 7 is closed with respect to the inner frame 3. Even if it is deviated from the position, it can be reliably guided to the engaging recess 26 along the inclination.

Further, the fraud prevention pieces 22A to 22I are formed with convex portions or concave portions for joining the fraud prevention pieces to each other between adjacent fraud prevention pieces. And the adjacent fraud prevention piece is joined by making a convex part and a recessed part fit, and the gap which arises between adjacent fraud prevention pieces is closed.
Here, a joint portion between the anti-tampering piece 22A and the anti-tampering piece 22B will be described with reference to FIG. As shown in FIG. 6, a convex portion 30 is formed at one end of the fraud prevention piece 22A, and a concave portion 31 is formed at one end of the fraud prevention piece 22B facing it. And the fraud prevention piece 22A and the fraud prevention piece 22B which adjoin each other by joining the convex part 30 and the recessed part 31 are joined.

  Subsequently, a joint portion between the tamper-proof piece 22C and the tamper-proof piece 22D will be described with reference to FIG. As shown in FIG. 7, a convex portion 32 is formed at one end of the fraud prevention piece 22C, and a concave portion 33 is formed at one end of the fraud prevention piece 22D facing it. And the fraud prevention piece 22C and the fraud prevention piece 22D which adjoin each other are joined by making the convex part 32 and the recessed part 33 fit. Similarly, although not illustrated, a joint portion between the tamper-proof piece 22B and the tamper-proof piece 22C, a joint portion between the tamper-proof piece 22D and the tamper-proof piece 22E, a joint portion between the tamper-proof piece 22E and the tamper-proof piece 22F, The joint between the anti-fraud piece 22G and the anti-fraud piece 22H and the joint between the anti-fraud piece 22H and the anti-fraud piece 22I are also joined by fitting the concave and convex portions.

  Here, the anti-fraud pieces 22A to 22I fitted by the convex portions and the concave portions can be slid independently toward the door member 7 so as not to interfere with each other's adjacent anti-fraud pieces. It is supported. That is, as shown in FIG. 8, when a force is applied from the direction of the door member 7 to the tamper-proof piece 22A, only the tamper-proof piece 22A is affected without affecting the movement of the adjacent tamper-proof piece 22B. Moves in the direction of the inner frame 3. Then, when the biased force is released, only the anti-fraud piece 22A moves in the direction of the door member 7 by the bias of the coil spring 23 without affecting the movement of the anti-fraud piece 22B.

Accordingly, as shown in FIG. 9, for example, an unauthorized person tries to open a gap between the upper part of the door member 7 and the upper part of the inner frame 3 with the intention of forming a gap for inserting the piano wire. When the member 7 bends outward, the anti-fraud piece 22D and the anti-fraud piece 22C move to the door member 7 side by different amounts as the gap 35 between the door member 7 and the inner frame 3 widens. As a result, the gap 35 generated between the door member 7 and the inner frame 3 can be blocked to a minimum by the fraud prevention piece.
At this time, compared with the case where the fraud prevention pieces 22A to 22I are integrally formed, the divided fraud prevention pieces 22A to 22I cause the gap 35 to be gradually formed corresponding to the gap 35 that gradually spreads from below to above. It can be closed.

As described above, in the pachinko machine 1 according to the present embodiment, the fraud prevention pieces 22A to 22I provided in the circumferential direction of the inner frame 3 stroke the inside of the storage recesses 21A and 21B based on the biasing force from the coil spring 23, Since the gap between the inner frame 3 and the door member 7 is configured to be closed, even if the door member 7 or the inner frame 3 is bent when the goto action is performed, the gap is kept to a minimum and the piano It becomes possible to prevent intrusion of foreign matters such as wires.
Further, since the fraud prevention pieces 22A to 22I for closing the gap apart from the coil spring 23, which is an elastic member, are used as dedicated members, it is not necessary to consider the presence or absence of elasticity when selecting the material and the like. By selecting the material, it is possible to prevent the fraud prevention pieces 22A to 22I from being damaged even when a strong force is applied by a piano wire or the like.
Further, since the fraud prevention pieces 22A to 22I are housed in the housing recesses 21A and 21B, even if the fraud prevention pieces 22A to 22I are supported and stroked stably and the door member 7 is repeatedly opened and closed many times. Further, it is possible to prevent the gap between the door member 7 and the inner frame 3 from being widened as compared with the case where the whole of the fraud prevention pieces 22A to 22I is made of an elastic member.
Furthermore, since the anti-tampering pieces 22A to 22I for closing the gap are used as dedicated members in addition to the coil spring 23 that is an elastic member, the anti-tampering pieces 22A to 22I are compared with the case where the whole is made of an elastic member. 22I can be made longer, and even when the door member 7 and the inner frame 3 are greatly distorted, it is possible to keep foreign matter to a minimum and prevent the entry of foreign matter such as a piano wire.
The tamperproof pieces 22A to 22I are divided into a plurality of pieces along the circumferential direction of the inner frame 3, and one divided tamperproof piece is a door member independently of the other tamperproof pieces adjacent to each other. 7 is slidably supported. Therefore, even when a wide gap such as between the door member 7 and the inner frame 3 is closed with a fraud prevention piece, even if the inner frame 3 or the door member 7 is bent, the bent inner frame 3 or It becomes possible to block the gap stepwise along the door member 7 by a plurality of fraud prevention pieces. As a result, the gap between the door member 7 and the inner frame 3 can be minimized.
Further, in the divided fraud prevention pieces 22A to 22I, a convex portion is formed on one adjacent fraud prevention piece, and a concave portion that fits the convex portion is formed on the other fraud prevention piece. Since the fraud prevention pieces are configured by respectively fitting them, it is possible to prevent foreign matters such as piano wires from entering through the gaps between the divided portions of the fraud prevention pieces 22A to 22I.

In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning.
For example, the storage recesses 21A and 21B are formed not in the inner frame 3 but in the circumferential direction of the door member 7, and the fraud prevention pieces 22A to 22I and the coil springs 23 are stored in the storage recesses 21A and 21B. Also good. At that time, by forming the engaging recess 26 on the surface of the inner frame 3 facing the door member 7, the gap between the inner frame 3 and the door member 7 can be closed by the fraud prevention pieces 22A to 22I. Become.

  Moreover, the said structure which block | closes the clearance gap which arises in the pachinko machine 1 by fraud prevention piece 22A-22I is not between the inner frame 3 and the plate 12 with which the top plate 11 was provided not between the inner frame 3 and the door member 7. It is good also as applying to. In that case, it comprises a storage recessed part along the circumferential direction of the inner frame 3 or the plate 12, and accommodates a fraud prevention piece and a coil spring.
