Next, the structure of the fraud prevention member 30 will be described.
[First Embodiment]
FIG. 5 and FIG. 6 are diagrams for explaining the structure of the anti-fraud member 30 according to the first embodiment. That is, FIG. 5 is a perspective view showing the appearance of the tamper-proof member 30. 6 is a cross-sectional view of the tamper-proof member 30, (a) is a cross-sectional view taken along line VIa-VIa in FIG. 5, and (b) is a cross-sectional view taken along line VIb-VIb in FIG. is there.
As illustrated in FIG. 5 or FIG. 6, the tamper-proof member 30 includes a main body portion 31 that forms the main body of the tamper-proof member 30 and a part from the main body portion 31 in the forward direction (frontward direction in FIG. 5; left direction in FIG. 6). Are provided with two projecting pieces 32 projecting to the front and claw 33 formed extending downward at the tip of each of the two projecting pieces 32. The protruding piece 32 and the claw 33 constitute a claw attaching portion 51 for attaching the main body 31 to the lower horizontal frame member 14.

  More specifically, the protruding piece 32 is configured to be able to bend with respect to the main body 31. Therefore, when the fraud prevention member 30 is attached to the lower horizontal frame member 14, the protruding piece 32 bends upward, and the claw 33 is hooked on the lower horizontal frame member 14 with the protruding piece 32 bent. The fraud prevention member 30 is attached to the lower horizontal frame member 14 by hooking the claw 33 on the lower horizontal frame member 14.

Further, as shown in FIG. 5 or FIG. 6, the tamper-proof member 30 is located below the protruding piece 32, and has a concave receiving portion 34 that receives the edge of the lower horizontal frame member 14, and the protruding piece 32. A plurality of ribs 35 located on the lower side and projecting forward from the main body 31. It can also be said that the plurality of ribs 35 are formed so that the receiving portion 34 is formed.
In addition, the plurality of ribs 35 have substantially the same height, and therefore the anti-fraud member 30 includes a contact surface 36 as an example of a contact portion constituted by end surfaces of the plurality of ribs 35. . The contact surface 36 is formed so as to stand in a direction opposite to the direction in which the standing wall portions 41 and 42 stand from the main body portion 31.

Further, the tamper-proof member 30 includes an urging portion 37 that protrudes from the contact surface 36 and has a tip portion that is formed to have a spring property. Further, the fraud preventing member 30 includes an abutting portion 38 formed at one end portion in the longitudinal direction (the back side in FIG. 5) and an abutting portion formed at the other end portion in the longitudinal direction (the near side in FIG. 5). 39.
When the fraud preventing member 30 is attached to the lower horizontal frame member 14, the urging portion 37 is deformed. Specifically, the front end portion of the urging portion 37 is retracted by contact with the rear surface of the lower horizontal frame member 14, whereby the front end portion presses the rear surface of the lower horizontal frame member 14. Furthermore, the contact surface 36 contacts the rear surface of the lower horizontal frame member 14, and each of the abutting portions 38 and 39 contacts the rear surface of the corner member 15. That is, the abutting portion 38 abuts on the rear surface of the corner member 15 connected to the lower end portion of the left vertical frame member 12, and the abutting portion 39 is connected to the lower end portion of the right vertical frame member 11. It contacts the rear surface.

To explain further, when the fraud prevention member 30 is attached to the lower horizontal frame member 14, when the protruding piece 32 is bent upward, the contact surface 36 comes into contact with the rear surface of the lower horizontal frame member 14 with a strong force. The urging portion 37 and the abutting portions 38 and 39 abut against the rear surface of the corner member 15 with a strong force. Even after the fraud prevention member 30 is attached to the lower horizontal frame member 14, these abutments are maintained, and the engagement between the protruding pieces 32 and the claws 33 and the lower horizontal frame member 14 is maintained. The provision of the urging portion 37 facilitates the work of fitting the tamper-proof member 30 into the lower horizontal frame member 14.
As described above, the fraud prevention member 30 is fraudulent even without a mounting part such as a screw due to the interaction of the protruding piece 32, the claw 33, the receiving portion 34, the rib 35, the abutting surface 36, and the abutting portions 38 and 39. The prevention member 30 can be more firmly attached to the lower horizontal frame member 14. Moreover, the anti-tamper member 30 once attached to the lower horizontal frame member 14 is difficult to come off due to the bending action of the protruding piece 32.

Further, as shown in FIG. 5 or FIG. 6, the anti-fraud member 30 includes an extending portion 40 that extends rearward from the main body portion 31 (backward direction in FIG. 5, right direction in FIG. 6), and an extending portion 40. And standing wall portions 41 and 42 formed so as to rise from the rear end. The fraud prevention member 30 includes a rib 43 that extends forward from the upper ends of the standing wall portions 41 and 42. The ribs 43 are formed on the surfaces of the standing wall portions 41 and 42 on the side where the claw attaching portion 51 is located. The extending portion 40, the standing wall portions 41 and 42, and the rib 43 are formed over substantially the entire length in the longitudinal direction of the main body portion 31.
As shown in FIG. 6, the tamper-proof member 30 includes ribs 44 that are positioned on the lower surface of the extending portion 40 and connect the extending portion 40 and the main body portion 31 to increase rigidity. The ribs 44 are formed at predetermined intervals with respect to the longitudinal direction of the main body 31.
As described above, the fraud preventing member 30 includes the extending portion 40 and the standing wall portions 41 and 42 and also includes the ribs 43 and 44 to prevent the extending portion 40 and the standing wall portions 41 and 42 from being bent. .

In addition, the tamper-proof member 30 includes a partition portion 45 formed by a wall for partitioning in the longitudinal direction. The partition portion 45 is located closer to one end portion in the longitudinal direction (the back side in FIG. 5). In other words, by providing the partition portion 45, a situation in which a wire as an unauthorized jig is inserted is dealt with.
The fraud prevention member 30 is formed in a shape for preventing interference with peripheral components. For example, the fraud prevention member 30 includes notches 46 and 47 in the main body 31 for preventing interference with the sliding portion 17. Further, the fraud preventing member 30 includes a notch 48 in the main body 31 for preventing interference with the front frame 20. Further, the fraud prevention member 30 includes notch portions 49 and 50 in the standing wall portions 41 and 42 for preventing interference with the front frame 20.

FIG. 7 is a cross-sectional view of the vicinity of the upper portion of the curtain plate 16 when the fraud prevention member 30 is attached.
As shown in the figure, when the fraud prevention member 30 is attached to the lower horizontal frame member 14 of the outer frame 10, the main body 31 of the fraud prevention member 30 is provided on the rear side of the lower horizontal frame member 14. Further, the standing wall portions 41 and 42 of the fraud preventing member 30 are located on the rear side of the front frame 20. Further, the protruding piece 32 of the fraud preventing member 30 protrudes in a direction crossing the lower horizontal frame member 14.

The fraud prevention member 30 attached to the lower horizontal frame member 14 is arranged so that the gap S at the upper part of the curtain plate 16 is reduced or the gap S is eliminated. More specifically, considering individual differences of the pachinko gaming machine 100 due to tolerances in manufacturing parts and workability during assembly, it may be difficult to completely eliminate the gap S even with the anti-fraud member 30. In such a case, a fraudulent jig (not shown) used for fraudulent acts may be inserted through the slightly formed gap S. Therefore, even if such an improper jig is strongly inserted from the gap S, it is necessary to prevent the standing wall portions 41 and 42 from bending backward.
In this regard, in the present embodiment, a structure for preventing the deflection of the standing wall portions 41 and 42 is employed. Specifically, the ribs 43 are formed on the standing wall portions 41 and 42, and the ribs 44 are formed on the lower surface of the extending portion 40.
Further, by forming the ribs 43 on the standing wall portions 41 and 42, even if an unauthorized jig (not shown) is inserted from the gap S, the unauthorized jig (not shown) gets over the standing wall portions 41 and 42. Further, it is prevented from entering the inside or moving upward.

Here, various modifications can be considered for the present embodiment.
FIG. 8 is a view for explaining the structure of an anti-fraud member 60 according to a modification. In addition, since the basic structure of the anti-fraud member 60 is the same as that of the anti-fraud member 30, the same reference numerals are used for common portions, and the description thereof may be omitted.
The fraud prevention member 60 shown in the figure includes a rib 61 extending obliquely downward instead of the rib 43 (see FIG. 6) extending forward from the upper ends of the standing wall portions 41 and 42. The rib 61 has an angle between the standing wall portions 41 and 42 that is not substantially a right angle, but smaller than an acute angle, that is, 90 degrees. For this reason, it is possible to more reliably prevent an unauthorized jig (not shown) from climbing over the standing wall portions 41 and 42 and further entering the interior or moving upward.

  Moreover, in this Embodiment, the main-body part 31 of the fraud prevention member 30 is a longitudinal shape, and the structure which attaches one fraud prevention member 30 per one game machine 100 is employ | adopted, However A shape is also conceivable. For example, when the short-shaped fraud prevention member 30 is attached only to the center portion of the lower horizontal frame member 14, a plurality of the anti-fraud members 30 are attached to one gaming machine 100 along the length direction of the lower horizontal frame member 14. Conceivable.

[Second Embodiment]
Next, a second embodiment will be described.
FIG. 9 is a view for explaining the structure of the anti-fraud member 70 according to the present embodiment. (A) of the figure is a cross-sectional view of the fraud prevention member 70, and (b) is a perspective view showing a part of the fraud prevention member 70. In addition, since the basic structure of the anti-fraud member 70 is common to the anti-fraud member 30, the same reference numerals are used for common portions, and the description thereof may be omitted.
As shown in the figure, the tamper-proof member 70 includes a standing wall portion 71 formed so as to rise from the rear end of the extending portion 40. The standing wall portion 71 is formed to have a wave shape along the longitudinal direction of the fraud preventing member 70 (one direction of the main body portion 31). This wave shape continuously changes in the width direction (direction intersecting the longitudinal direction) as it proceeds in the longitudinal direction of the fraud prevention member 70. Further, in addition to the case where the wave shape is formed so that the same change is repeated, a case where the wave shape is irregularly changed in the width direction is also conceivable.

The standing wall portion 71 does not change in the height direction. That is, if the position of the fraud prevention member 70 in the longitudinal direction is the same, the shape of the standing wall portion 71 in the height direction is the same. However, it is also conceivable to configure the shape of the standing wall 71 in the height direction to change.
In the present embodiment, by providing the wave-like standing wall portion 71, even if an unauthorized jig (not shown) is inserted, the movement of the unauthorized jig (not shown) reaching the standing wall portion 71 is corrugated. It becomes possible to regulate by.

  More specifically, unlike the case of the first embodiment, the fraud prevention member 70 does not include the rib 43 (see FIG. 5 or 6) extending forward from the upper ends of the standing wall portions 41 and 42. Such standing wall portion 71 increases the rigidity of the standing wall portion 71 itself, so that it is possible to ensure the necessary rigidity without the rib 43 in the case of the first embodiment. Of course, in the present embodiment, it is conceivable to provide the ribs 43 as in the first embodiment.

  As described above, in the first embodiment and the second embodiment described above, it is possible to eliminate the gap S at the upper part of the curtain plate 16, and it is not possible to use the slightly remaining gap S. Even if the correct jig is inserted, it is possible to prevent reaching the target location inside the pachinko gaming machine 100.

It is a schematic front view of the pachinko gaming machine according to the present embodiment. It is a figure explaining the pachinko game machine concerning this embodiment. It is a perspective view explaining the structure of a frame member. It is a perspective view which shows the external appearance of an outer frame.
