On the other hand, when the above-described ball removal button 22 (see FIG. 1) is pressed, the ball removal slider 50 slides against the urging force of the coil spring 49, and the blocking wall 50 </ b> A is retracted from the firing ball supply path 47. . Then, the bent path 47A and the game ball discharge path 48 are in communication with each other, so that the game balls on the upper plate 27 pass through the launch ball passing path 47, the game ball discharge path 48, and the discharge port 46F. Move to. In addition, from the base end side part of the ball removal slider 50, the connection shaft part 50J protrudes in the horizontal direction orthogonal to the sliding direction. The connecting shaft portion 50 </ b> J protrudes from the front surface of the case 41 through a long hole 44 </ b> B formed in the inner cover 44 and a long hole 46 </ b> E formed in the vertical wall 46 </ b> A of the cover body 46. Although not shown, the connecting shaft portion 50J and the ball removal button 22 can be connected inside the lower dish door 32.

  The ball feed lever 51 includes a rotation shaft 51J protruding in the front-rear direction, and the rotation shaft 51J is interposed between the vertical walls 42A and 46A of the case 41 so as to be vertically movable. A ball receiving portion 52 having a size for receiving just one game ball is formed at the end of the ball feeding lever 51 away from the rotation shaft 51J. The ball receiving portion 52 is opened in a substantially horizontal direction (front-rear direction) parallel to the rotation shaft 51J, can be communicated with the firing ball supply hole 45, and is opened to the outside in the rotational radial direction so as to pass through the firing ball. Communication with the terminal opening 47X (see FIG. 10) of the path 47 is possible. Of the ball feeding lever 51, the upper portion of the ball receiving portion 52 is a ball contact portion 53 that can be opposed to the terminal opening 47 </ b> X, and the lower portion of the ball receiving portion 52 is vertically moved inside the firing ball supply hole 45. It is a moving ball rolling part 54. A metal suction member 55 is provided on the upper surface of the ball feed lever 51. The ball feed lever 51 is always arranged at the lower end position. At this time, the ball contact portion 53 faces the terminal opening 47X and dams up the game ball in the shot ball passage 47. In addition, the ball receiving portion 52 is aligned with the firing ball supply hole 45, so that the game ball in the ball receiving portion 52 can be discharged to the outside from the firing ball supply hole 45 (the state shown in FIG. 12A). ).

  A solenoid 56 is assembled above the ball feed lever 51 in the case 41. When the solenoid 56 is excited, the attracting member 55 is attracted and the ball feed lever 51 rotates upward against its own weight. Then, as shown in FIG. 12 (B), the ball receiving portion 52 and the terminal opening 47X of the launching ball passageway 47 are in contact with each other, and of the game balls in the launching ball passageway 47, The leading game ball that is in contact with the ball is received by the ball receiving unit 52. At this time, since the ball rolling part 54 moves upward and the opening area between the opening edge of the launching ball supply hole 45 and the ball rolling part 54 is narrowed, the launching ball supply hole 45 leads to the launching rail 62. No game balls are released.

  When the solenoid 56 is demagnetized and the ball feed lever 51 is returned to the lower end position as shown in FIG. 12C, the game ball subsequent to the game ball taken into the ball receiving portion 52 is moved by the ball contact portion 53. The game ball that has been dammed up and taken into the ball receiving portion 52 is released onto the firing rail 62 from the firing ball supply hole 45 by the downward slope of the upper surface of the ball rolling portion 54. That is, each time the ball feed lever 51 rotates up and down, one game ball is supplied onto the launch rail 62. Here, the turning operation of the ball feeding lever 51 is interlocked with the striking operation of the striking rod 63 of the launching device 60, and every time the striking rod 63 reciprocates to launch one game ball, the launching ball is supplied. The device 40 supplies one game ball on the firing rail 62.

  Now, in order to regulate fraud by the “game ball with operation line” in which an operation line W1 such as a thread or a piano wire is attached to the game ball, the launch ball supply device 40 has a fraud prevention member 80 shown in FIG. It is attached.

  The fraud prevention member 80 is made of, for example, a plate member such as a sheet metal, and has a structure in which the side plate portion 82 is bent at a right angle from the main plate portion 81. Both the main plate portion 81 and the side plate portion 82 have a flat plate shape, and a screw insertion hole 83 is formed through the side plate portion 82 at a position closer to the end portion on the side away from the main plate portion 81. The fraud prevention member 80 is fixed to the outer surface of the firing ball supply device 40 by an attachment member such as a screw 89 passed through the screw insertion hole 83 (see FIG. 8).

  A cut portion 84 is formed in the main plate portion 81 at a position near the end portion 81 </ b> A away from the side plate portion 82. The cut portion 84 is formed by arranging a pair of blade portions 84A and 84B arranged in the same plane parallel to the main plate portion 81 in a substantially V shape. The cut portion 84 opens to the lower side of the main plate portion 81 and becomes narrower as it goes upward. Of the pair of blade portions 84A and 84B, the blade portion 84B disposed on the side away from the side plate portion 82 (position closer to the end portion 81A) extends in parallel with the side plate portion 82. On the other hand, the blade portion 84A disposed on the side plate portion 82 side extends in an inclined manner so as to move away from the side plate portion 82 toward the upper side (to approach the blade portion 84B).

Lower continuous to the blade portion 84A of the main plate portion 81 is inclined so as to be directed upward as approaching from the side plate portion 82 to the blade portion 84A, and has a guide join the club 85A. Further, a corner portion and the lower side of the blade portion 84B and the main plate portion 81 intersect is curved in a substantially arc shape, and has a the corner portion is also electrically join the club 85B.

  The fraud prevention member 80 is formed by bending a sheet metal 90 (blank material) punched into a predetermined shape by pressing, and the sheet metal 90 before being bent is shown in FIG. As shown in the figure, the sheet metal 90 is composed of a first strip plate portion 91 constituting the main plate portion 81 of the fraud preventing member 80 and a second strip plate portion 92 constituting the side plate portion 82.

  A screw insertion hole 83 is formed through the end of the second strip plate portion 92 away from the first strip plate portion 91. The screw insertion hole 83 is formed simultaneously when the sheet metal 90 is punched out by pressing. Further, when the first band plate portion 91 and the second band plate portion 92 are bent at a right angle by a second bending line L2 set between the first band plate portion 91 and the second band plate portion 92. The second belt plate portion 92 becomes the side plate portion 82 of the fraud preventing member 80 as it is.

  The first band plate portion 91 has a band plate shape extending in a direction away from the second fold line L2. The first strip 91 is formed with a bay portion 96 (corresponding to the “notch portion” of the present invention) opened at one side edge in the width direction (direction parallel to the second fold line L2). ing. The bay portion 96 is provided at a position closer to the tip of the first strip plate portion 91 away from the second strip plate portion 92. The bay portion 96 becomes narrower toward the back, and the flat plate portions 93 and 94 on both sides of the bay portion 96 are integrally connected by a neck portion 95 left on the back side of the bay portion 96. Further, at the end of the neck portion 95 on the flat plate portion 94 side, a constricted portion 95A formed by cutting out both sides in the width direction is formed. Hereinafter, in order to distinguish the flat plate portions 93 and 94 on both sides of the bay portion 96, the flat plate portion 93 on the base end side (the second strip plate portion 92 side) from the bay portion 96 is referred to as a “first flat plate portion 93”. The flat plate portion 94 on the tip side from the bay portion 96 (the side opposite to the first flat plate portion 93 across the bay portion 96) is referred to as a “second flat plate portion 94”. The second flat plate portion 94 corresponds to “a flat plate portion on the tip side from the notch portion” of the present invention.

  The second flat plate portion 94 has a rectangular shape including a side 94 </ b> C that is the inner side of the bay portion 96 and a side 94 </ b> A that is the tip of the first strip 91 as a pair of parallel long sides. Yes. Further, each corner of the rectangle is rounded.

  The first flat plate portion 93 has an asymmetric quadrangular shape with a larger area than the second flat plate portion 94. Of the first flat plate portion 93, the side 93 </ b> A that is the inner side of the bay portion 96 is inclined so as to be separated from the second flat plate portion 94 toward the open end of the bay portion 96. In the side 93A, a side 93B constituting one side edge of the first band plate portion 91 intersects at an obtuse angle, and the intersecting corner 93C has a rounded shape.

  And if the 1st strip board part 91 is folded by the 1st fold line L1 which crosses the bay part 96 in the width direction (folded 180 degree | times), the main board part 81 of the fraud prevention member 80 will be formed.

  Specifically, the first fold line L1 is set so as to cross the end portion of the neck portion 95 on the second flat plate portion 94 side, that is, the constricted portion 95A that is particularly narrow in the neck portion 95, When the first strip 91 is folded along the first fold line L1, the second flat plate portion 94 is overlapped with the neck portion 95, the bay portion 96, and a part of the first flat plate portion 93. . That is, the main plate portion 81 includes the first flat plate portion 93 and the neck portion 95 as “a pair of plate pieces” located on both sides of the first fold line L1 (fold portion 86) in the first strip plate portion 91. And the second flat plate portion 94 is folded.

  When the first belt plate portion 91 is folded along the first fold line L1, a cut portion 84 is formed at a portion where the first flat plate portion 93 and the second flat plate portion 94 do not overlap each other. Specifically, the edge of the side 94 </ b> A that overlaps the bay portion 96 of the second flat plate portion 94 (the edge of the tip of the first strip plate portion 91 in the unfolded state) and the bay portion 96 of the first flat plate portion 93. The edge of the side 93A, which is the inner side, is arranged in a substantially V shape in the same plane as the overlapping surface of the first flat plate portion 93 and the second flat plate portion 94, and these two edges are paired with a pair of blade portions 84A, A cut portion 84 provided as 84B is formed. Further, in the second flat plate portion 94, a corner portion 94B that is rounded continuously to the side 94A serves as an introduction portion 85B in the fraud prevention member 80, and a rounded crossing angle in the first flat plate portion 93. The part 93 </ b> C and the side 93 </ b> B continuous with the part 93 </ b> C serve as the introduction part 85 </ b> A in the fraud prevention member 80.

As shown in FIG. 8, the fraud prevention member 80 is attached to the outer surface of the firing ball supply device 40 where the firing ball supply hole 45 is opened, that is, the rear surface of the vertical wall 42A facing the launching device 60 side. . More specifically, as shown in FIGS. 15 and 16, the rear surface of the vertical wall 42 </ b> A is attached above the firing rail 62 and the firing ball supply hole 45.

  On the rear surface of the vertical wall 42 </ b> A, a wall-like support wall 70 erected toward the base 61 is formed. The support wall 70 extends obliquely upward from above the firing ball supply hole 45. Specifically, the support wall 70 extends parallel to the upper surface of the firing rail 62 and is disposed with a gap of one or more game balls between the upper surface of the firing rail 62 (see FIG. 16). A stepped recess 70 </ b> A is formed at an intermediate portion in the vertical direction of the support wall 70. The stepped recess 70A holds the side plate portion 82 of the tamper-proof member 80 sandwiched in the vertical direction.

  As shown in FIG. 15, an obliquely extending groove 72 is formed at a position adjacent to the downward slope of the support wall 70 on the rear surface of the vertical wall 42A. The groove portion 72 is disposed at a side position of the stepped recess 70A when viewed from the rear surface side of the vertical wall 42A. The inclination angle of the groove portion 72 with respect to the horizontal plane is larger than the inclination angle of the support wall 70 with respect to the horizontal plane. For example, the inclination angle of the support wall 70 is about 45 degrees parallel to the firing rail 62, while the inclination angle of the groove 72 is about 60 degrees. For this reason, the groove part 72 approaches the downward slope of the support wall 70 as it goes upwards.

  As shown in FIG. 16, the end portion 81 </ b> A (see FIG. 13) of the main plate portion 81 of the fraud prevention member 80 that is separated from the side plate portion 82 is inserted into the groove portion 72. Thus, a relatively sharp wedge-shaped region is formed between the downward slope of the support wall 70 and the main plate portion 81 of the fraud prevention member 80.

Here, of the end portion 81A of the main plate portion 81, the upper portion is constituted by a bent portion 86 formed by bending along the first bend line L1, and the lower portion is constituted by a second flat plate portion 94. Yes. That is, the upper end portion 81A of the main plate portion 81 has a thickness approximately twice that of the lower portion. Since the cross-sectional shape of the groove portion 72 substantially matches the cross-sectional shape of the end portion 81A of the main plate portion 81, the groove portion 72 can prevent the bent portion 86 from expanding and deforming.

As shown in FIG. 15, the vertical wall 42 </ b> A of the case body 42 is formed with a wedge-shaped slit 71 (corresponding to the “guidance part” of the present invention) that is continuous with the firing ball supply hole 45. The wedge-shaped slit 71 extends from the upper end corner portion of the projecting ball supply hole 45 to a wedge-shaped region formed between the downward slope of the support wall 70 and the main plate portion 81 of the fraud prevention member 80 and heads upward. According to the width.

  A mounting column 73 is provided above the firing ball supply hole 45 in the vertical wall 42 </ b> A of the case body 42. The mounting column 73 has a cylindrical shape protruding from the vertical wall 42A toward the base 61, and a screw hole 73A is formed at the center. The mounting column 73 and the support wall 70 are connected by a plurality of reinforcing ribs 73R. The front end surface of the mounting column 73 and the bottom surface of the stepped recess 70A are flush with each other, and the side plate portion 82 of the fraud prevention member 80 is assigned to the front end surface and the bottom surface. Then, a screw 89 penetrating through the screw insertion hole 83 of the side plate portion 82 is fastened to the screw hole 73A (see FIG. 16).

  In other words, when attaching the fraud prevention member 80 to the firing ball supply device 40, the fraud prevention member 80 is brought closer from the direction orthogonal to the rear surface of the firing ball supply device 40, and the end portion 81 </ b> A of the main plate portion 81 is inserted into the groove portion 72. And the side plate 82 is fitted into the stepped recess 70A. At this time, the fraud prevention member 80 is temporarily fixed to the rear surface of the firing ball supply device 40. In this state, the screw 89 approached from the direction orthogonal to the rear surface of the launch ball supply device 40 is passed through the screw insertion hole 83 of the side plate portion 82 and fastened to the screw hole 73A of the mounting column 73. Thus, the tamper-proof member 80 is fixed to the rear surface of the firing ball supply device 40. Since the operation of inserting the main plate portion 81 into the groove portion 72 and the screwing operation of the side plate portion 82 can be performed from the same direction, the workability of attaching or replacing the tamper-proof member 80 is improved. Further, since the main plate portion 81 and the side plate portion 82 of the tamper-proof member 80 can be fixed by the groove portion 72 and the screw 89, the wobble of the tamper-proof member 80 can be prevented.

  The fraud prevention member 80 fixed to the rear surface of the firing ball supply device 40 has a side plate portion 82 arranged in parallel with the vertical wall 42A of the case body 42 and includes a main plate portion 81 (that is, a pair of blade portions 84A and 84B). (Plane) is arranged at right angles to the vertical wall 42A of the case body 42. Further, the main plate portion 81 is disposed on the front side in the direction of launching the game ball with respect to the launch ball supply hole 45 (obliquely above the launch ball supply hole 45). Furthermore, the main plate portion 81 is disposed to be inclined with respect to the horizontal direction so that the distance from the firing rail 62 increases toward the upper end portion of the firing rail 62. Specifically, the inclination angle of the launch rail 62 with respect to the horizontal plane is about 45 degrees, whereas the inclination angle of the main plate portion 81 with respect to the horizontal plane is about 60 degrees, and the main plate has an angular difference of about 15 degrees. The interval between the portion 81 and the firing rail 62 gradually increases as it goes upward.

  The configuration of the present embodiment has been described above, and the operation will be described next. When the operation knob 24 of the bullet ball game machine 10 is turned, game balls are supplied one by one on the firing rail 62 from the firing ball supply device 40. The hitting ball 63 performs a hitting operation in synchronism with the supply operation of the shot ball supply device 40, and the game ball bounced by the hitting ball 63 is guided to the game area R1 by the shooting rail 62 and the guide rail 12. Then, when the game balls flowing down the game area R1 enter the winning holes 14A, 14B, 15, 20 and the start gate 18 and the like, the game according to the entry proceeds.

  By the way, the game ball B1 with the operation line thrown into the upper plate 27 by the fraudulent person is supplied from the upper plate 27 to the launch rail 62 through the launch ball supply device 40 in the same manner as the regular game ball, and the launch rail 62 (see FIG. 7). At this time, the operation line W1 is led out to the upper plate 27 through the inside of the launching ball supply device 40 (the launching ball supply hole 45, the launching ball passage 47, and the ball entrance 46D), and is held by an unauthorized person. .

  In this state, when the operation knob 24 is operated, the game ball B1 with an operation line is bounced by the hitting ball 63 and is launched obliquely upward along the launch rail 62 in the same manner as a regular game ball. At this time, the game ball B1 with operation line passes through the side of the launch ball supply hole 45 and heads obliquely upward, and the operation line W1 enters the wedge-shaped slit 71 from the launch ball supply hole 45 as shown in FIG. To do. As shown in the change from FIG. 17 to FIG. 18, when the game ball with operation line B <b> 1 moves further upward, the operation line W <b> 1 enters the cut portion 84 of the fraud prevention member 80. Here, even if the trajectory of the operation line-equipped game ball B1 fired from the launching device 60 varies somewhat, the operation line W1 is surely cut by the introduction parts 85A and 85B formed on the side of the cut part 84. Can be directed to section 84.

  Then, as shown in FIG. 18, before the game ball with operation line B1 reaches the game area R1, the operation line W1 is a pair of blade portions 84A and 84B at the back of the cut portion 84 (see FIG. 14). Is caught in and captured. Alternatively, the operation line W1 is cut by the blade portions 84A and 84B. At this time, the blade portions 84A and 84B bite into the operation line W1 obliquely from the front side in the traveling direction of the game ball.

  When the operation line W1 is cut, the game ball with operation line B1 stalls in the middle of the guide rail 12 or in front of the guide rail 12, and is collected in the return ball collection duct 33. If the operation line W1 is cut, the operation line-equipped game ball B1 cannot be used for fraud. Further, even if the operation line W1 is cut and enters the game area R1 as it is, there is no problem because the game ball B1 with the operation line is not in a state where it can be operated from the outside of the ball game machine 10. .

  When the operation line W1 is captured by the notch 84, the game ball B1 with the operation line enters the return ball collection duct 33. The game ball B1 with an operation line that has entered the return ball collection duct 33 does not come out to the lower plate 28 unless the catching by the cut portion 84 is released. Even if the gaming ball B1 with the operation line comes out to the lower plate 28 and is cheated again, the manipulation line W1 is captured or cut by the fraud prevention member 80 as described above.

  Thus, according to the ball ball game machine 10 of the present embodiment, when the game ball B1 with an operation line is supplied to the launching device 60 through the launching ball supply hole 45 and is launched by the launching device 60, the launching is performed. The operation line W1 is caused to enter the cut portion 84 of the fraud prevention member 80 disposed in the vicinity of the ball supply hole 45, and the operation line W1 is cut by the pair of blade portions 84A and 84B in the cut portion 84. Or can be captured. Thereby, the fraudulent act which tries to gain profit illegally by the game ball B1 with an operation line can be controlled.

  Further, since the notch 84 is formed by bending one sheet metal 90 along the first fold line L1, the tamper-proof member 80 can be manufactured relatively easily.

  That is, the cut portion may be formed by shearing a sheet metal into a V shape, but in order to cut or capture the operation line W1, the cut portion needs to have a relatively sharp acute angle. It is very difficult to form a simple notch by shearing alone. Further, if the cut portion is formed by shifting and bonding the two sheet metals, a relatively sharp cut portion can be formed, but there is a problem that it takes time and effort.

  On the other hand, according to the present embodiment, the cut portion 84 is formed by folding one sheet metal 90 (more precisely, the first strip plate portion 91) along the first fold line L1. Therefore, it is not necessary to form a cut portion by bonding a plurality of sheet metals as in the prior art, and the number of parts constituting the fraud prevention member 80 can be reduced and it can be manufactured relatively easily.

  In addition, when the first strip 91 of the sheet metal 90 is bent at the first fold line L1, the narrow neck 95 remaining on the back side of the bay portion 96 may be folded. The bending operation 91 can be performed relatively easily.

  Further, since the fraud prevention member 80 is provided on the rear surface of the launch ball supply device 40, it is possible to prevent fraud (such as removal or destruction) that disables the fraud prevention member 80.

  Further, the bent portion 86 of the main plate portion 81 of the fraud preventing member 80 along the first fold line L1 is inserted into a groove portion 72 formed on the outer surface of the firing ball supply device 40 (the rear surface of the vertical wall 42A). Therefore, it is possible to prevent the bending portion 86 from expanding and deforming and cutting or capturing the operation line W1 from being deteriorated.

  Here, for example, when the end portion 81 </ b> A of the main plate portion 81 is configured to abut on the outer surface of the firing ball supply device 40, an operation is performed between the end portion 81 </ b> A of the main plate portion 81 and the outer surface of the firing ball supply device 40. There may be a problem that the line W1 enters and the capture or cutting of the operation line W1 by the cut portion 84 is avoided. In order to prevent such a problem, it is necessary to abut the end portion 81A of the main plate portion 81 against the outer surface of the firing ball supply device 40, and a high degree of component accuracy and assembly accuracy are required. On the other hand, according to the present embodiment, since the end portion 81A of the main plate portion 81 is configured to be inserted into the groove portion 72 on the outer surface of the firing ball supply device 40, the above-mentioned problems are not required without requiring high accuracy. Can be prevented.

That is, the plane including the pair of blade portions in the cut portion may be arranged so as to be parallel to the first outer surface of the firing ball supply device.

  [Reference Example 1] The tamper-preventing member according to the present invention may be a structure having a substantially V-shaped notch capable of capturing or cutting the operation line W1, and is exemplified in the above embodiment. In addition, for example, a structure as shown in FIGS. 19A and 20A may be used. That is, as shown in FIGS. 19B and 20B, a sheet metal 110 punched into a predetermined shape is bent along a first fold line L1, and a pair of sheet metal pieces 101, 102 (corresponding to the “sheet piece” of the present invention) are partially folded to form the anti-fraud member 100 shown in FIGS. 19A and 20A. Of the pair of sheet metal pieces 101 and 102, The configuration is such that the edges 101E and 102E of the portions 101A and 102A that are not folded on each other are arranged in a substantially V shape within the same plane as the overlapping surface of the pair of sheet metal pieces 101 and 102 to form the cut portion 100V. It is good.

  In the fraud prevention member 100 shown in FIG. 19A, the sheet metal pieces 101, 102 on both sides of the first fold line L1 in the sheet metal 110 shown in FIG. The substantially V-shaped first cutout portion 101V formed and the substantially V-shaped second cutout portion 102V formed in the other sheet metal piece 102 partially overlap each other to form an edge of the first cutout portion 101V. A substantially V-shaped cut portion 100V having a sharper angle than the first cutout portion 101V and the second cutout portion 102V is formed between the edge 101E that is a portion and the edge 102E that is the edge portion of the second cutout portion 102V. Is formed.

  Reference Example 2 The fraud prevention member 100 shown in FIGS. 19A and 20A has one end thereof (for example, the end where the bent portion formed by the first bend line L1 is formed) as described above. Like the main plate portion 81 in the embodiment, it is inserted into the groove portion 72 formed on the first outer surface of the projecting ball supply device 40 (specifically, the rear surface of the vertical wall 42A where the projecting ball supply hole 45 is opened) and attached. May be. That is, the plane including the pair of blade portions (edges 101E and 102E) in the cut portion 100V may be arranged so as to be perpendicular to the first outer surface of the firing ball supply device 40.

  [Reference Example 3] Alternatively, similarly to the above-described modification (2), the fraud prevention member 100 is laid on the first outer surface (specifically, the rear surface of the vertical wall 42A in the above embodiment) of the firing ball supply device. Thus, the cut portion 100V may be disposed at the opening edge of the projecting ball supply hole. That is, a plane including the pair of blade portions in the cut portion may be arranged so as to be parallel to the first outer surface of the firing ball supply device 40.

  [Reference Example 4] In the above embodiment, the incision 84 is formed by folding the sheet metal 90 along the first fold line L1 (bending 180 degrees). For example, the fraud prevention member 200 shown in FIG. In this way, the sheet metal is bent at an acute angle at the first fold line L1, and the edges 201E and 202E of the sheet metal pieces 201 and 202 disposed on both sides of the first fold line L1 are arranged in a substantially V shape and cut.
