The glass unit 75 is fixed to the hook 95 and the holding plates 97 and 98 by a fixing member in a state of being in close contact with the back surface of the door frame 61. A fixed state in the region R1 and the region R2 surrounded by the two-dot chain line will be described with reference to FIGS.

  First, the region R1 will be described. As shown in FIGS. 8, 9, and 20, the clamp unit 60 is suspended and supported in the housing portion 59. In the present embodiment, only the basic structure of the clamp unit 60 will be described. A lever 106 is pivotally supported by a pivot shaft 104 at the center of the case 105 of the clamp unit 60. In the case 105, clamp pins 107 and 108 are respectively arranged at the left and right positions sandwiching the lever 106 and shifted in the front-rear direction. Both clamp pins 107 and 108 are members having the same shape and are arranged opposite to each other so that the distal ends thereof are directed in the left-right direction. The shaft 104 is pivotally supported at the opposite portions across the shaft 104. As a result, a link mechanism is formed between the clamp pins 107 and 108 and the lever 106. Both clamp pins 107 and 108 are guided by the long hole 110 as the lever 106 rotates, and slide the case 105 to the left and right.

  When the lever 106 is in a position protruding forward as shown in FIG. 20A, both the clamp pins 107 and 108 are retracted in the case 105. Then, by rotating the lever 106 to a position where the lever 106 is accommodated within the thickness of the case 105 in FIG. 20B, the tips of the clamp pins 107 and 108 protrude from the case 105 in the left-right direction. In such a configuration, the hook 95 is accommodated in a state in which both the clamp pins 107 and 108 are retracted into the case 105 as shown in FIG. 20A, that is, in a state in which the both clamp pins 107 and 108 do not interfere with the hook 95. It is accommodated in the part 59. That is, the case 105 of the clamp unit 60 is disposed between the left and right hooks 95. Then, as shown in FIG. 20 (b), the lever 106 is rotated so that the clamp pins 107 and 108 protrude from the case 105 and advance to the front positions of the left and right hooks 95. As a result, the hook 95 is pressed by the clamp pins 107 and 108 and fixed to the door frame 61 side (state shown in FIG. 8).

  Next, the region R2 will be described. In the present embodiment, the clamp levers 58 are disposed at three locations. However, in order to avoid overlapping description, the detailed description is represented by the region R2. The glass unit 75 is disposed in the mounting space 57. As shown in FIG. 19, positioning pins 111 formed on the back surface of the door frame 61 are arranged in the positioning holes 110 formed in the positioning plate 96. The clamp lever 58 includes a rotating shaft 112 and a pressing arm 113. The pressing arm 113 of the clamp lever 58 fixes the pressing plate 97 at the position shown by the solid line in FIG. 18B and FIG. 20 in the use shown in FIG. On the other hand, a stopper 115 and a pressing hill 116 are formed at a position adjacent to the clamp lever 58 on the rear surface of the door frame 61. The pressing hill 116 is a gently curved hill-shaped protrusion, and interferes with the back surface of the pressing arm 113 to prevent the clamp lever 58 from moving freely. Accordingly, when not in use, the clamp lever 58 contacts the stopper 115 and is held by the pressure hill 116 and is held at the position indicated by the phantom line in FIGS.

  As shown in FIGS. 2, 3, and 4, various control devices are arranged in an overlapping manner on the back surface of the main body frame 14 (game board 27). The control device is roughly divided into three units, and includes a tank 120, a game ball supply device 121 for supplying game balls, a first unit 124 including a protective cover 123, a main control device and an audio lamp control device. The second unit 125 includes a third unit 126 including a payout control device, a launch control device, and a power supply device.

Description will be made with reference to FIG. FIG. 7 is a diagram supplementing FIG. 6, in which the portion other than the game surface 27 a is omitted on the main body frame 14 side, and the structure of the recess 84 in the bulging portion 80 is omitted from the glass frame 76 and overlapped. is there. In the pachinko gaming machine 11, since the diagram of the members overlapping in the front-rear direction becomes difficult to understand, it is difficult to illustrate the overlapping state of the members in a single drawing. Therefore, FIG. 7 is represented by omitting the subordinate members other than the main part of the present invention.

  As shown in FIGS. 6 and 7, in a state in which the door frame 61 is closed with respect to the main body frame 14, the inner area surrounded by the protrusions 82 of the glass frame 76 substantially matches the game area. In this embodiment, the distance between the rear surface 81B of the glass frame 76 (flat plate portion 81) and the game surface 27a is set to 19.5 mm, and the distance between the rear surface 81B and the front end of the inner rail 52 is also set to 3 mm. ing. The distance between the glass frame 76 and the game surface 27a takes into account the size of the pachinko ball, the amount of protrusion of various members (such as the liquid crystal display 36 and the windmill 43) arranged on the game surface 27a, and the amount of protrusion of the game nail. It is set. As a result, the front surface of the gaming surface 27a is not in contact with the gaming surface 27a, and the glass unit 75 disposed on the rear surface of the door frame 61 is disposed, and a gaming ball (pachinko ball) that falls in the gaming area is also provided. However, it does not spill from the gap between the inner rail 52 and the glass unit 75 between the main body frame 14 and the door frame 61. In the state where the door frame 61 is closed with respect to the main body frame 14, the sealing plate portion 92 has a pachinko ball launch passage 49 formed between the outer rail 51 and the inner rail 52 as shown in FIG. It is arranged on the front face so as to be generally sealed. That is, since the front side of the pachinko ball launch passage 49 is sealed by the sealing plate portion 92 and the rear glass plate 78 does not face, the pachinko balls passing through the pachinko ball launch passage 49 are directed to the rear glass plate 78. There is no problem that the glass surface is scratched or broken due to contact.

  As shown in FIG. 7, the inner periphery of the glass frame 76 defined by the ridges 82 is disposed near the inner rail 52 and below the inner rail 52 (outside in a broad sense). As described above, the distance between the rear surface 81B of the glass frame 76 and the front end of the inner rail 52 is 3 mm. However, since the flange portion 99 having a maximum length of 5 mm protrudes rearward from the rear surface 81B, FIGS. As shown, the inner rail 52 and the collar 99 are overlapped. In FIG. 7, at the AA position, which is the lowest position of the inner rail 52, the flange 99 protrudes 5 mm rearward from the rear surface 81 </ b> B, so that the front end of the inner rail 52 overlaps 2 mm as shown in FIG. 21. Also, even at a position slightly swung from the AA position in the left-right direction, for example, the BB position, the collar portion 99 protrudes 5 mm rearward from the rear surface 81B, and as shown in FIG. Become.

  However, at a position where the vertical component increases from the lowest position to the inner rail 52 (here, close to both sides of the curved inner rail 52), the interference between the inner rail 52 and the flange 99 is prevented when the door frame 61 is opened. There is a need to. In the present embodiment, for example, as shown in FIG. 12 and the like, the collar portion 99 is tapered so that the protruding amount decreases toward the end near the left and right sides as the vertical component increases. Therefore, for example, at the CC position, as shown in FIG. 23, the overlapping amount with the front end of the inner rail 52 is smaller than the above position (about half here). As described above, the flange 99 is overlapped with the lower side of the inner rail 52 in a relatively wide range below the inner rail 52. In addition, the inner rail 52 is not disposed at the DD position relatively spaced from the passage 68 on the back surface of the tray 67. However, at this position, the partial wall surface 31 of the window hole 29 defining the game area is slightly offset toward the game area side, and the glass frame 76 overlaps the front plate portion 30 as shown in FIG.

With the configuration as described above, the above embodiment has the following effects.
(1) If the flange 99 is not formed on the glass frame 76, a gap will be formed between the glass frame 76 and the front end of the inner rail 52, and those who attempt fraud are shown in FIG. It is possible to form a through hole communicating with the rear surface of the wall surface of the passage 68 and insert an elongated tool such as a wire to guide the wire from the gap to the game surface 27a. However, in the present embodiment, when the door frame 61 is closed on the main body frame 14, the collar portion 99 is disposed in a lower position of the inner rail 52 with respect to the inner rail 52. Even if it is going to be inserted, since the gap is shielded by these overlapping relationships, it is difficult to guide the wire to the game surface 27a. Even if it can be derived, since the operation tends to take a very long time, the deterrent effect is great. As a result, it becomes difficult to carry out fraudulent acts that increase the interval between game nails.

  (2) Since the buttock 99 is overlapped at the lower position of the inner rail 52, there is no structural change in the game area, and the player is not affected by the game content depending on the presence or absence of the buttock 99. Absent. Further, since the collar 99 moves away from the position overlapping with the inner rail 52 together with the door frame 61 as the door frame 61 is opened, when the door frame 61 is opened for inspection on the main body frame 14 side. The collar 99 does not interfere with the inspection work.

  (3) In the above embodiment, the flange 99 is formed at the lower position of the glass frame 76. Of course, theoretically, it is possible to form the flange 99 in a wider range than the above embodiment, that is, in the upper direction of the glass frame 76. However, if the flange 99 is formed in a very wide range, the flange 99 may interfere with the inner rail 52 when the glass frame 76 is deformed such as torsion due to aging or heat. However, in the present embodiment, such a problem is unlikely to occur because the collar portion 99 is formed within the minimum necessary range.

  (4) Since the collar portion 99 is formed on the glass frame 76 disposed on the back surface of the door frame 61 conventionally, a member added for preventing fraud is intentionally disposed between the door frame 61 and the main body frame 14. Therefore, there is no major design change, and work is not delayed due to the provision of extra members during assembly and inspection.

  (5) Since the glass frame 76 has a large opening at the center and a thin member such as the thin frame portion 79, the glass frame 76 has a structure that is relatively easily deformed by twisting or the like. However, the strength is improved by forming the collar portion 99.

  (6) The collar 99 protrudes so as to protrude rearward from the rear surface 81B of the glass frame 76, but does not have such a large thickness that it hardly interferes with a member on the game board 27 side arranged in the protruding direction. In addition, when the “escape” is set on the game board 27 side so as not to interfere with the heel portion 99, a large design change is not required.

  (7) Since the eaves part 99 is formed at a position very close to the glass plates 77 and 78 along the curve of the glass frame 76, the player passes the eaves part through the glass plates 77 and 78 during the game from the front of the door frame 61. 99 can be visually observed. In other words, since it can be seen from the outside that the anti-fraud measures are being taken, it is possible to expect a deterrent effect to prevent fraud using an elongated tool such as a wire.

(8) Since the inner rail 52 is formed in an arc shape, a vertical component is generated near both the left and right sides. At this time, if the collar part 99 protrudes too long rearward, the door frame 61 may rotate together with the door frame 61, and the collar part 99 may interfere with the inner rail 52 to open the door frame 61. Arise.
However, in the present embodiment, the flange portion 99 is reduced in the protruding amount with the increase in the vertical component near both the left and right sides where the vertical component increases, so that the member interference due to the opening of the door frame 61 does not occur. It has become.

The present invention can be implemented with the following modifications.
As shown in FIG. 25, a string member 121 as a silicone rubber sealing member may be fixed to the upper surface of the collar portion 99. The string member 121 is a solid body having a flexible circular cross section, and is disposed in contact with the rear side glass plate 78 over the entire length of the collar portion 99 in the longitudinal direction. If such a string member 121 is provided, the following effects can be obtained in addition to the effects of the above embodiment. (1) The space between the inner rail 52 and the flange 99 becomes narrower, and it becomes more difficult to insert an unauthorized operation instrument. (2) By fixing the string member 121 to the base of the collar 99, the strength of the collar 99 itself can be improved. (3) Since the string member 121 is flexible, it can be easily deformed by pressing. Therefore, since there is some width between the inner rail 52 and the flange 99 and the string member 121 partially deforms even when it abuts against the inner rail 52, the door frame 61 is caused by the interference of the string member 121. The problem that the main body frame 14 is not closed is less likely to occur. In addition, by positively contacting the string member 121 to the inner rail 52, it contributes to the improvement of the sealing performance during this time. In addition, the cross-sectional shape of the string member may be square. Moreover, since it is a square, an attachment surface becomes a plane, and it becomes easy to attach. It is also possible to use an elastic and flexible member such as a sponge other than silicone rubber.

-As shown to Fig.26 (a) and (b), it is also possible to adhere the string member 121 not to the root of the collar part 99 but to the tip end of the collar part 99. FIG. FIG. 26 (a) shows an embodiment in which the overlapping amount of the flange 99 and the inner rail 52 is relatively large. FIG. 26B shows an embodiment in which the overlapping portion 99 and the inner rail 52 are closer, although the overlapping amount is not so much. In such a configuration, the string member 121 becomes invisible to the player by the inner rail 52, so that even if the manipulation tool is skillfully manipulated to sew between the collar 99 and the inner rail 52 to advance, the string is difficult to see. It is extremely difficult for the member 121 to get in the way. Therefore, it becomes more difficult to perform fraud.

  As a modification of FIG. 25, the inner rail 52 and the string member 121 may be more closely attached when the door frame 61 is closed. At that time, as shown in FIG. 29, it is also possible to configure the strap member 121 to have a cross-sectional shape that forms an inclined portion 121a inclined in the direction of the inner rail 52. With this configuration, the inclined portion 121a gradually comes into contact with the lower surface of the inner rail 52 as the door frame 61 is closed, and the string member 121 is further pressed. The insertion of the instrument becomes even more difficult. Further, the cord member 121 is not crushed at the front end of the inner rail 52, and the cord member 121 is not peeled off from the collar portion 99 due to excessive frictional force. The shape of the inclined portion 121a is not limited to FIG.

It is also possible to attach the string member 121 to the inner rail 52 side rear surface.
-The string member 121 does not necessarily need to be flexible. This is because the effect (1) can be expected.
-The string member 121 does not need to be arrange | positioned in the full length of the inner rail 52 or the collar part 99. FIG.

As shown in FIG. 25, the sides of the flange portion 99 may be configured with the same width over the entire length without being tapered as in the above embodiment. For example, as shown in FIG. 27, the interval between the overlapping inner rail 52 and the flange 99 is sufficiently separated so that the flange 99 does not hit the inner rail 52 even when the door frame 61 is opened. It is because it is good.

In the above embodiment, the flange 99 is formed integrally with the glass frame 76 by molding. However, as shown in FIG. 28, the flange 99 is formed separately and fixed to the rear surface 81B of the glass frame 76. You may do it. Further, the fixing may not be performed with an adhesive, and may be detachable with a fastening member such as a screw 122.

-The structure of the said glass frame 76 is an example, Comprising: It is not limited to this. For example, in the above embodiment, the glass unit 75 is pivotable with respect to the door frame 61 and can be opened and closed. The method for attaching the glass unit 75 to the door frame 61 is not particularly limited. That is, as described above, it is possible to use other fixing means without using the clamp unit 60 and the clamp lever 58.

In the above-described embodiment, the collar portion 99 is formed at the lower position of the glass frame 76. However, the collar portion 99 may be further extended around the formation position.
In the above embodiment, the inner circumference defined by the ridges 82 of the glass frame 76 is substantially elliptical, but it may be circular or square, for example. Moreover, although the collar part 99 was extended along the flat plate part 81 and eventually extended along the glass plates 77 and 78, it needs to be extended along the glass plates 77 and 78. There is no.
In the above embodiment, the flange 99 as the protruding portion protrudes from the glass frame 76. However, the present invention is not originally limited to the glass frame 76 as the formation position of the protruding portion.

In the pachinko gaming machine 11 of the above embodiment, the upper receiving tray 67, the lower receiving tray 71, and the game ball launching handle 73 are disposed on the door frame 61, but the present invention is a panel body separate from the door frame 61. It is also free to apply to a pachinko gaming machine in which a lower tray and a handle for launching a game ball are arranged. -In the above embodiment, it was applied to a so-called first type pachinko gaming machine with a start opening, but if it is a pachinko gaming machine that can prevent fraud due to the relationship between the rail member and the protrusion formed on the door body side, It doesn't matter. In the above embodiment, as shown in FIGS. 12 to 14, the tapered portions 99 a are formed near the left and right sides of the collar portion 99, but the pachinko balls falling through the pachinko ball launching passage 49 are the collar portions. If it is intended to prevent collision with 99, the tapered portion 99a may be formed only on the side facing the pachinko ball launch passage 49. Moreover, as long as it can avoid the collision of the falling pachinko ball to the collar part 99, it may have a shape other than the tapered part 99a. In addition, it is free to implement in a mode that does not depart from the spirit of the present invention.
