Tabs 18a and 19a are formed on the outer periphery of the vertical side 15a, tabs 18b and 19b are formed on the outer periphery of the vertical side 15b, and tabs 18a and 19a are formed on the outer periphery of the vertical side 15b, and tabs 18a and 19a are formed on the outer periphery of the vertical side 15b, and the outer diameter is the same as that of the frame-like member of the body 100. A wide tab 18c is formed. Note that these tabs 18a, 19a, 18b, 19b, and 18c are formed in the same position and shape as the tab 101 formed on the frame member of the general transparent plate assembly 100 described above. Therefore, by engaging the engaging member 12 with each of the tabs 18a, 19a, 18b, 19b, and 18c in the same manner as the general transparent plate assembly 100, it can be attached to and detached from the back side of the transparent plate holding frame 4. It can be attached to. Note that 18a', 19a', 18b', 19b', and 18c' indicate positioning holes formed in each of the tabs 18a, 19a, 18b, 19b, and 18c. Further, locking portions 20a and 21a are formed integrally in a triangular shape on the inner peripheral side of the vertical side 15a of the frame-like member 15, and similar locking portions 20b and 21a are formed on the inner peripheral side of the vertical side 15b. 21b is integrally formed, similar locking parts 20c, 21c are integrally formed on the inner peripheral side of the horizontal side 15c, and similar locking parts 20d, 21d are integrally formed on the inner peripheral side of the horizontal side 15d. ing. Each of the locking portions 20a, 21a, 20b, 21b, 20c, 21c, 20d, and 21d is located within the opening 5 of the transparent plate holding frame 4 and faces the outside of the gaming area 9b of the gaming board 9. Formed at the site. Therefore, the locking portions 20a, 21a, 20b, 21b, 20c, 21c, 20d, and 21d do not obstruct the player's view of the gaming area 9b.

A substantially keyhole-shaped mounting hole 22 is formed in each of the locking portions 20a, 21a, 20b, 21b, 20c, 21c, 20d, and 21d. A member 23 is housed. The locking member 23 has engaging pieces 23b and 23c integrally formed on the outer periphery of a shaft portion 23a so as to protrude in mutually orthogonal directions, and a hook-shaped portion 23d is formed at the tip of one of the engaging pieces 23b, One end 24a of a coiled spring 24 wound around the shaft portion 23a is locked to a spring locking portion 23f formed on the engagement piece 23b.

A substantially triangular notch 16a is formed in the peripheral edge portion to expose the locking portions 20a, 21a, 20b, 21b, 20c, 21c, 20d, and 21d to the front. Therefore, when the front side transparent plate 16 is fitted into the recessed step portion 15f and the frame member 15 is attached, the surface of the transparent plate assembly 10 becomes flat without any step.
Further, the rear side transparent plate 17 is also made of a substantially rectangular transparent plate made of glass or resin, and the rear side transparent plate 17 is fitted into the inner peripheral edge of the back side of the frame member 15. A recessed step portion 15g having the same depth as the thickness of 17 is formed. Note that the rear transparent plate 17 does not have a cutout 16a formed in the front transparent plate 16. Then, by fitting the rear side transparent plate 17 into the recessed step portion 15g and pasting the rear side transparent plate 17, the rear side of the transparent plate assembly 10 also becomes flat with no step. By attaching the rear transparent plate 17 in this manner, the rear transparent plate 17 presses the other end 24b of the coiled spring 24, so that the elasticity of the coiled spring 24 causes the hook-shaped portion 23d to It is biased in the direction of the hook tip.

The transparent plate assembly 10 configured as described above has the above-described engagement tabs 18a, 19a, 18b, 19b, and 18c on the back side of the transparent plate holding frame 4, instead of the general transparent plate assembly 100 described above. It is attached by engaging the mating member 12, and at that time, as shown in FIG. becomes.

Next, the decorative body 30 will be explained according to FIGS. 8 to 15. The decorative body 30 is designed to harmonize with the design of the game board 9 and the display of the symbol display device 13, and in this example, as shown in FIG. 12, each decorative piece 30a made of resin is divided into four. The design has sawtooth-like unevenness formed on the 30d surface. Each of the decorative pieces 30a to 30d has a linear outer surface and a substantially circular inner surface so that it can cover the front surface of the transparent plate holding frame 4 from the area facing the outside of the game area 9b. It is formed in an arc shape. Then, as shown in FIGS. 14 and 15 on an enlarged scale, round bar-shaped connecting members 31a and 31b are fixed on the back side of each of the decorative pieces 30a to 30d at a portion of the locking member 23 that faces the engaging piece 23b. The connecting members 31a and 31b are made to protrude from the back side of each of the decorative pieces 30a to 30d. Note that, as shown in FIG. 6, a notched engagement groove 31f is formed on one side of the connecting members 31a, 31b. Also, a penetrating hole is inserted into a portion of each of the decorative pieces 30a to 30d that is close to the connecting members 31a and 31b and faces the engagement piece 23c of the locking member 23, to the back side of each of the decorative pieces 30a to 30d. Needle holes 32a and 32b are formed.

As shown in FIGS. 13(a) and 13(b), the decorative body 30 configured in this manner has the connecting members 31a, 31b of the decorative pieces 30a to 30d connected to the respective locking portions 20a, 21a, 20b, 21b. , 20c, 21c, 20d, and 21d, and the hook-shaped portion 23d of the locking member 23 is engaged with the engagement groove 31f of each connecting member 31a, 31b. In this way, by simply inserting the connecting members 31a and 31b of each decorative piece 30a to 30d into the mounting hole 22, the connecting members 31a and 31b engage with the hook-shaped portion 23d, and the connected state is determined by the elasticity of the coiled spring 24. Therefore, the decoration body 30 can be easily and reliably attached. By attaching the decorative body 30 in this manner, the decorative body 30 covers not only the front surface of the transparent plate holding frame 4 but also the outside of the ball guide rail 9a of the game board 9. However, since the decorative body 30 does not cover the game area 9b within the ball guide rail 9a, it does not obstruct the player's view looking through the game area 9b. Since the decorative body 30 can expand the range of decoration, even more luxurious and dynamic decoration is possible.

Furthermore, although not shown, by using connecting members 31a and 31b that are longer than a certain level, each of the decorative pieces 30a to 30d can be separated from the surface of the transparent plate assembly 10 and the surface of the transparent plate holding frame 4. However, it becomes possible to attach the decorative body 30 in a state where it appears to be floating in the air. Therefore, by appropriately setting the lengths of the connecting members 31a and 31b, it is possible to construct an unprecedented and novel design. Although not shown, it is also possible to adopt a design in which the decorative body 30 has a narrow shape so that it does not reach the top, bottom, left, and right ends of the transparent plate holding frame 4, and the transparent plate holding frame 4 is intentionally exposed on the surface. It is. In other words, it is possible to change the pinball game machine to a pinball game machine in which a free design can be applied to decorate all or part of the transparent plate holding frame 4 using the decorative body 30 that can be added.

Further, as shown in FIG. 14(a), a needle tool 33 is inserted into the needle holes 32a and 32b, and the engagement piece 23c of the locking member 23 is pressed against the elastic force of the coiled spring 24 with the tip of the needle tool 33. When pressed against this, the hook-shaped portion 23d separates from the engagement groove 31f and the connecting members 31a, 31b can be pulled out, so that the decorative body 30 is removed as shown in FIG. 14(b). It is also possible to easily replace it with another newly designed decoration. In this case, the needle holes 32a and 32b are always exposed on the surface of the decorative body 30, but each decorative piece 30a to 30d is attached by a plurality of (in this case two) connecting members 31a and 31b. Therefore, the decorative pieces 30a to 30d cannot be removed unless the two connecting points are released at the same time, and it is difficult for the player to remove the decorative pieces 30a to 30d for mischief or illegal purposes. Even if the game board 30d is removed, the game board 9 is always protected by the transparent plate assembly 10, so fraudulent acts are completely prevented as before.

Further, the rear side transparent plate 17 attached to the back side of the transparent plate assembly 10 also faces the outside part of the game area 9b of the game board 9, which may be caused by the notch 16a in the front side transparent plate 16. Since it is completely flat with no slight difference in level, even if a batted ball moving at high speed on the ball guide rail 9a comes into contact with the rear transparent plate 17, there is no risk that the flight of the batted ball will be altered by this. do not have.

Further, in the embodiment shown in FIG. 16, a rectangular engagement hole 34 is formed in the upper wall surface of the decorative piece 30c, and the upper side of the transparent plate holding frame 4 is inserted into the engagement hole 34 as shown in FIG. It is configured so that a wedge-shaped protrusion 35 formed on the top surface can be fitted into it, and by connecting the decorative piece 30c also on the top wall surface, the decorative piece 30c is more secure than when held only by the locking part. The piece 30c can be more firmly attached to the transparent plate holding frame 4.
Note that, as in this embodiment, the decorative body 30 may be only the decorative piece 30c that decorates only the upper side of the transparent plate holding frame 4.
The protrusion 35 is specifically realized by utilizing a decorative body protruding from the transparent plate holding frame of the gaming machine from the beginning or a movable decorative body for performance.
The front side of the transparent plate holding frame on which the additionally provided decorative body is located means the outside of the gaming area of the game board and the front side of the transparent plate holding frame, and is not the same as the transparent plate holding frame. In a game machine where the ball tray opens and closes integrally with the ball tray, it is possible to decorate the ball tray with an additional decorative section.

The front transparent plate 16 and the rear transparent plate 17 may be made of glass or resin, but the front transparent plate 16 is preferably made of resin for ease of machining the notches 16a, etc. Reasonable. Further, in this embodiment, two transparent plates 16 and 17 are arranged at the front and rear, but if security is sufficient, only one plate may be used, or three or more transparent plates may be provided as necessary. In that case, only the foremost transparent plate may be made of resin, and the other transparent plates may be made of glass. Note that when a transparent plate made of resin is adopted for the front transparent plate 16, the frame member 15 is also made of resin, and the front transparent plate 16 and the frame member 15 are integrally molded by injection molding. be able to.

In this embodiment, the connecting members 31a and 31b protruding from the back surface of the decorative body 30 are attached to the locking parts 20a, 21a, 20b, 21b, 20c, 21c, 20d, and 21d of the transparent plate assembly 10. Although the decorative body 30 is attached by inserting it into the hole 22, it is not necessary to adopt such a mounting structure. For example, a connecting member protruding from the transparent plate assembly 10 can be attached to the decorative body 30. It may be locked on the back side.

Next, an embodiment of the present invention according to claim 4 will be described with reference to FIGS. 18 to 21. In this embodiment, the locking portion 40 is formed by forming the front surface of the tab 18c formed on the peripheral edge of the transparent plate assembly 10 into a concave shape as shown in enlarged views in FIGS. 19 and 20. A plurality of small cylindrical engagement protrusions 42 projecting into the locking portion 40 are formed on the front surface of the locking portion 40 which is recessed. On the other hand, regarding the decorative piece 30c, a width plate-shaped connecting member 43 that can be loosely fitted into the recessed locking part 40 is fixed to the rear edge of the decorative piece 30c, and the connecting member 43 is attached to the connecting member 43. A circular engagement hole 44 into which the engagement protrusion 42 can fit is formed. Therefore, as shown in FIG. 21, by housing the connecting member 43 in the locking portion 40 and fitting the engaging protrusion 42 into the engaging hole 44, the transparent plate assembly 10 and It becomes possible to connect the decorative piece 30c. In actual assembly, the decorative piece 30c is inserted from the front side of the transparent plate holding frame 4, and after connecting the decorative piece 30c with the transparent plate assembly 10 approached from the back side of the transparent plate holding frame 4, This is done by aligning the transparent plate assembly 10 with the opening 5 of the transparent plate holding frame 4 and engaging the engaging members 12 with the respective tabs 18a, 19a, 18b, 19b, and 18c.
