Therefore, in the state where the transparent plate holding frame 5 is closed and locked, the notch concave portion 30b of the protruding plate portion 29 on the shaft support side of the inner frame body 4 is formed on the protruding strip portion 30a on the upper end surface of the transparent plate holding frame 5. By engaging with, the operation is prevented even if the shaft support side of the transparent plate holding frame 5 is pulled out to the front side. Thereby, the said fraud is prevented. In addition, when the transparent plate holding frame 5 is opened, the protruding portion 30a and the cutout concave portion 30b move to the side and the engagement is naturally released, and the transparent plate holding frame 5 can be opened and closed. It can be done without any trouble.
[0015]
On the shaft support side of the inner frame body 4, as shown in FIG. 9, a multi-axis hinge 31 for connecting the transparent plate holding frame 5 to the front surface thereof is provided. The multi-axis hinge 31 is a double biaxial hinge having two link plates and is made of metal, and is arranged in a pair on the front surface of the inner frame body 4, and as shown in FIGS. 10 and 11, the inner frame body 4.

On the other hand, the support member 32b attached to the transparent plate holding frame 5 side is also formed by bending the side plate 35 from the both end edges of the bottom plate 34 in the same direction at substantially right angles, and the dimensions between the side plates 35 are the link plates 33a, 33b. Is set so that the link plates 33a and 33b can rotate between them. Similarly, the two side plates 35 are provided with two pairs of shaft holes 36 facing each other, and one of the side plates 35 has an introduction groove opened at the outer edge of the side plate 35. It communicates with 36a.
[0017]
Each of the link plates 33a and 33b is formed in a horizontally long shape, and a rod-shaped shaft portion 39 that is inserted into and supported by the shaft holes 36 is integrally provided at both end edges thereof. These rod-shaped shaft portions 39 protrude outward from the upper and lower end edges of the link plates 33a and 33b. One of the first link plates 33a is formed so that one part of the first link plate 33 is bent gently in the horizontal plane, and the other second link plate 33b is formed by bending two parts in the horizontal plane and in opposite directions.
[0018]
Reference numeral 40 denotes a metal connecting member for connecting the upper and lower first link plates 33a, and the support plates 40b and 40c having different heights from the both edges in the short direction of the vertically long substrate 40a are substantially perpendicular to the outside. Bent and molded. Then, the vertically long substrate 40a is brought into contact with one side surface of the upper and lower first link plates 33a so that the respective support plates 40b and 40c face the outside, and they are fixed by crimping. As a result, when the transparent plate holding frame 5 is opened and closed, the upper and lower first link plates 33a operate synchronously, and the operation deviation between the upper and lower multiaxial hinges 31 is reduced, so that the transparent plate holding frame 5 The wobble is suppressed. Reference numeral 41 denotes a metal mounting member for detachably mounting the transparent plate holding frame 5, and the outer plates 41 b and 41 c are bent substantially at right angles from the both lateral edges of the longitudinal long plate 41 a in the same direction. To be molded. The vertical abutment plate 41 a is provided with mounting ports 42 at the upper and lower portions thereof, and horizontal locking rods 43 are horizontally mounted so as to cross the mounting ports 42. The dimension between both locking rods 43 is the same as the dimension between the upper and lower mounting members 45 provided on the transparent plate holding frame 5 side described later. Then, the vertically long plates 41a are brought into contact with the bottom plates 34 of the respective support members 32b so that the respective support members 32b are fitted between the both outer plates 41b and 41c, and are fixed to each other by caulking.
[0019]
The transparent plate holding frame 5 is formed to have a size that covers the entire upper half of the inner frame body 4 over its entire width, and a circular opening 44 is formed at the center of the game board 14 in front of the game board 14 so that the game part can be visually recognized. The main frame 5a is made of a synthetic resin and a reinforcing metal plate 5b attached to the back side of the main frame 5a. The main body frame 5a is designed like a volcano with the outer peripheral edge of the opening 44 projecting to the front most, and the translucent part and the non-translucent part are intricately complicated. It is out. On the shaft support side of the reinforcing metal plate 5b, mounting members 45 for fitting to the respective locking rods 43 are fixed vertically on the upper and lower portions thereof by screws 45a. As shown in FIG. 12, each mounting member 45 is mounted on a support portion 46 screwed to the reinforcing metal plate 5b, and is mounted on the support portion 46 so as to be slidable in the vertical direction, and an inclined surface 47 is provided on the upper end thereof. The slider 48 and a spring 49 that constantly urges the slider 48 upward are provided with a U-shaped groove 50 that holds the locking rod 43 in the support portion 46.
[0020]
Therefore, in order to attach the multi-axis hinge 31 to the front surface of the inner frame body 4, as shown in FIG. 13 (a), one of the support members 32a in the upper and lower multi-axis hinges 31 is provided with its bottom plate 34 as the inner frame. It is arranged on the front surface of the main frame portion 11 so as to face the front surface of the main frame portion 11 of the body 4. Then, each screw hole 38 on each support member 32a side and the through hole 51 opened in the main frame portion 11 are matched with each other from the rear side of the main frame portion 11 as shown in FIG. A countersunk machine screw 52, which is a screw, is detachably screwed into the hole 38 through a through hole 51. At this time, the head 52 a of the countersunk screw 52 fits into the recess 37, and a part of the head 52 a does not protrude rearward from the rear surface of the main frame portion 11. No trouble is caused when the 14 is abutted and mounted. In this way, the support member 32a is attached to the inner frame body 4 side, but conversely, each support member 32a is removed from the inner frame body 4 by removing the countersunk machine screws 52 from the rear side of the main frame portion 11. Can be easily removed. Therefore, if the transparent plate holding frame 5 is tilted to the open side by its own weight and the multi-axis hinge 31 is bent or damaged due to this, the countersunk machine screw 52 is removed to remove the multi-axis from the inner frame 4. Remove hinge 31. At this time, since the transparent plate holding frame 5 is detachably attached to the attachment member 41 as described below, the transparent plate holding frame 5 can also be separated from the multi-axis hinge 31. Therefore, only the multi-axis hinge 31 is obtained as a result, and the new multi-axis hinge 31 can be easily replaced. Further, since only this replacement is sufficient, there is no waste and no extra cost is incurred. As long as it does not interfere with the mounting of the game board 14, the mounting means for the multi-axis hinge 31 to the inner frame body 4 may be other mounting means such as an engagement piece and an engagement hole. In addition, the multi-axis hinge can be applied to other types having a configuration different from that of the multi-axis hinge 31.
[0021]
On the other hand, in order to attach the transparent plate holding frame 5 to the mounting member 41, the mounting members 45 of the transparent plate holding frame 5 are attached to the upper and lower locking rods 43 of the mounting member 41 fixed to the other supporting members 32b. The transparent plate holding frame 5 is pressed against the mounting member 41 in a state in which the locking rod 43 is brought into contact with the inclined surface 47 of the slider 48 by being approached through the mounting port 42. As a result, the slider 48 moves backward against the bias of the spring 49 by the locking rod 43. Further, when the transparent plate holding frame 5 is pressed, the locking rod 43 is disengaged from the tip of the inclined surface 47 and fits into the U-shaped groove 50 of the support portion 46, and at the same time, the slider 48 is biased by the spring 49. Returning to the position, the locking rod 43 is held so as not to come off as shown in FIG. In this way, the transparent plate holding frame 5 is rotatably and detachably attached to the front side of the inner frame body 4 by the multi-axis hinge 31. Since the locking bar 43 is arranged horizontally, the transparent plate holding frame 5 is easy to attach, and when attached, the transparent plate holding frame 5 is firmly fixed and very stable. When removing the transparent plate holding frame 5 from the inner frame 4, the locking rod 43 is pulled out from the U-shaped groove 50 and removed while the slider 48 is retracted by a finger against the bias of the spring 49. do it.
[0022]
When the opened transparent plate holding frame 5 is gently closed, the upper and lower multi-axis hinges 31 are arranged such that, as shown by the solid line in FIG. Next, the tip edge of the outer side plate 41b inside the attachment member 41 comes into contact with the outer side surface of the second link plate 33b and stops once. At this time, the vertically long abutting plate 41 a of the mounting member 41, that is, the transparent plate holding frame 5 is inclined at a predetermined angle with respect to the front surface of the main frame portion 11 of the inner frame body 4 in the direction in which the transparent plate holding frame 5 opens. The predetermined angle A is preferably about 3.5 degrees, for example. When the transparent plate holding frame 5 is further pressed and closed toward the inner frame body 4 from this state as shown by a chain line in FIG. 15, the outer plate 41b pushes the second link plate 33b and flexes it against its elasticity. I will not.
[0023]
Thus, one rod-shaped shaft portion 39 (39a) serving as a fixed end of the second link plate 33b is positioned inside the outer plate 41b, and the other rod-shaped shaft portion 39 (39b) serving as a free end is disposed outside thereof. Therefore, in the state where the transparent plate holding frame 5 is finally closed and locked, the second link plate 33b is pushed toward the inner frame body 4 by the outer plate 41b of the mounting member 41 with a predetermined pressing force. And bends against its elastic force. As a result, the shaft support side of the transparent plate holding frame 5 is pulled toward the inner frame body 4 side. Therefore, in this state, the force to float to the front side of each multiaxial hinge 31 is prevented, and no unnecessary gap S is opened between the transparent plate holding frame 5 and the inner frame body 4. Therefore, this also prevents an illegal act of obtaining a prize ball by deliberately operating the winning device by causing a wire rod such as a piano wire to pass over the surface of the game board 14 from the gap S. Moreover, in the said state, the force which tries to open reversely acts on the side by which the transparent plate holding frame 5 is opened. Therefore, when the transparent plate holding frame 5 is opened, since the reaction force to open in advance is acting on the opened side, the transparent plate holding frame 5 naturally protrudes to the front side, so that it is easy to open.
[0024]
On the rear surface of the reinforcing metal plate 5b of the transparent plate holding frame 5, a groove frame member 53 is formed in a U-shape so as to surround the left and right side portions and the lower side portion excluding the upper side portion of the opening 44 of the main body frame 5a. It is provided integrally. Further, a transparent frame body 54 that is integrally assembled by arranging two glass plates 54 a as transparent plates that can be seen through the game board 14 in parallel with the groove frame member 53 is inserted and fitted from above. . Between the front surface of the reinforcing metal plate 5b and the main body frame 5a, the middle / high sound speaker 55 and the LED 56 exhibiting an electric decoration effect are disposed at appropriate positions. In the reinforcing metal plate 5b, a through hole 58 through which a cylinder lock 57 for locking the inner frame body 4 and the transparent plate holding frame 5 faces is provided on the open side, and correspondingly, the main body frame 5a is provided with a key insertion hole 59 through which the key hole portion 57a at the front end of the cylinder lock 57 faces.
[0025]
As shown in FIG. 16, a metal tamper-proof frame 60 into which the front end portion of the cylinder lock 57 can be fitted is provided on the rear surface of the main body frame 5a so as to correspond to the key insertion hole 59. The fraud prevention frame 60 is formed in a box frame shape with an open rear surface, and a flange portion 60a extending outward in a vertical plane is provided around the outer peripheral edge of the rear end, and a screw insertion hole 60b is provided in the flange portion 60a. Is provided. Then, the tamper-proof frame 60 is attached by screwing screws 62 into screw holes 61 provided on the rear surface of the main body frame 5a through the screw insertion holes 60b. An insertion hole 60 d communicating with the key insertion hole 59 is formed in the front side wall 60 c of the fraud prevention frame 60. Then, when the transparent plate holding frame 5 is closed as shown in FIG. 17, the keyhole portion 57a abuts on the front side wall 60c and matches the insertion hole 60d, thereby firmly closing the insertion hole 60d. The mounting position of the fraud prevention frame 60 and the inner diameter of the insertion hole 60d are set so that no gap is formed between the insertion hole 60d and the insertion hole 60d. Therefore, when the transparent plate holding frame 5 is closed, the insertion hole 60d is always closed by the key hole portion 57a, and the insertion hole 60d and the key hole portion 57a are passed through the through hole 58 along the side surface of the cylinder lock 57. Even if a thin wire such as a piano wire is inserted between the two, it becomes impossible to prevent fraud.
[0026]
The interval between the upper and lower walls 60e of the fraud prevention frame 60 is set to be slightly wider than the height dimension of the cylinder lock 57, and the inner surfaces thereof are slightly inclined so as to gradually spread rearward. Further, the inner peripheral edge of the rear end opening is curved so that the cylinder lock 57 can enter without being supported. Therefore, as shown in FIG. 18, when the transparent plate holding frame 5 is closed, the cylinder lock 57 is fitted in sliding contact with the fraud prevention frame 60, so that it also serves as a guide. It is possible to guide the key hole portion 57a to the normal position with respect to the key insertion hole 59 only by pushing in to the fourth side, and to close the transparent plate holding frame 5 smoothly. In addition, when the transparent plate holding frame 5 is closed, the tip of the cylinder lock 57 is fitted in the fraud prevention frame 60, so that the stability of the transparent plate holding frame 5 is increased.
[0027]
As shown in FIG. 3, the locking mechanism 63 of the inner frame 4 is assembled on the back side of the inner frame 4 and on the open side thereof. Further, a fixing plate 64 is fixed to a side edge portion located on the front side of the inner frame body 4 and on the open side thereof, and a locking mechanism 65 of the transparent plate holding frame 5 is assembled inside the fixing plate 64. ing. A vertically long case body 66 having a setting mechanism for using the cylinder lock 57 as a variable type is attached to the front surface of the fixed plate 64, and the cylinder lock 57 is fixed to the front surface thereof. Thereby, the cylinder lock 57 can be pulled out to the front side, and the key hole portion 57a can be aligned with the key insertion hole 59 even when the main body frame 5a is overhanging. Locking metal fittings 67 are attached to the upper and lower parts of the open side inner side surface of the outer frame 2, and an L-shaped lock metal fitting is provided on the open side surface of the groove frame member 53 provided on the back side of the transparent plate holding frame 5. 68 is fixed. Then, when a key (not shown) is inserted into the key hole portion 57a of the cylinder lock 57 and rotated in one direction, the locking mechanism 63 of the inner frame body 4 is actuated and each locking metal fitting 67 of the outer frame 2 is connected. Is disengaged, and the inner frame 4 can be opened. On the other hand, when the inner frame 4 is pressed against the outer frame 2 with the inner frame 4 opened, the locking mechanism 63 of the inner frame 4 automatically operates to lock the upper and lower portions of the outer frame 2. The inner frame 4 is locked to the outer frame 2 by being engaged with the metal fitting 67.
[0028]
In the locking mechanism 65 of the transparent plate holding frame 5, when the transparent plate holding frame 5 is in a closed state, the locking mechanism 65 of the transparent plate holding frame 5 and the upper and lower L-shapes of the transparent plate holding frame 5 are used. The transparent metal holding frame 5 is locked by engaging the locking metal fitting 68.
