[0005]
According to a second aspect of the present invention, in the positioning structure for the back partition plate according to the first aspect, the center accessory is a frame-shaped center frame mounted from the front side of the game board, and a game board. The ball path plate that is mounted on the center frame from the back side and the display plate that is fixed from the back side of the ball path plate.
[0006]
[Action]
In the invention according to claim 1 configured as described above, the center accessory is inserted from the surface side of the game board toward the inside of the through hole for attaching the center accessory formed on the game board. The center combination and the game board are positioned by the first positioning structure, and the center combination is fixed to the periphery of the through hole. On the other hand, on the back side of the game board, the center accessory and the back partition plate are positioned by the second positioning structure, and the back partition plate is mounted and fixed.
[0007]
Here, as the game board, for example, a game board of a pachinko machine, etc., other than this, a board surface on which a center frame of a wide accessory such as an arrangement ball is mounted may be used. For example, the center accessory includes a variable display device having a liquid crystal display, but may be a picture matching device having a normal rotating drum. Moreover, it does not necessarily need to be in the center position, and may be arranged in the peripheral position. The through-hole may be anything that allows the center character to penetrate, and the center character does not necessarily need to penetrate at this time, so that a part of the back partition plate is inserted from the back surface and connected to the center character. It can be anything.
[0008]
Examples of the first positioning structure for positioning the center accessory on the game board include an uneven fitting structure. A concave portion is formed on one side and a convex portion is formed on the other side. At this time, if the tip of the convex part is tapered or the opening part of the concave part is widened, the insertion becomes easy. In the case of a pachinko machine, a gauge plate is used to form all the pilot holes for nailing with a punch on the surface of the game board, and if a recess for alignment is formed with the punch of this gauge plate Overall alignment with surrounding winning devices and the like becomes possible.
[0009]
Similarly, as the second positioning structure for positioning the back partition plate and the center accessory, there is an uneven fitting structure or the like. In this case, an uneven shape that fits to each other may be formed at the contact portion between the end of the frame-shaped center accessory and the back partition plate, and a convex portion and a concave portion are formed respectively. It can be modified as appropriate.
Here, the center accessory is not necessarily inserted integrally from the surface of the game board, but may be partly inserted from the surface of the game board and partly attached from the back of the game board to be combined. . At this time, a part of the center accessory mounted from the back surface may also be used as a structure on the back side of the game board, for example, a part of the back partition plate can also be used as a ball path plate. . That is, the center frame is aligned on the front surface side, the spherical path plate is aligned with the center frame from the back side, and the display board is mounted on the spherical path plate to form a center accessory. Furthermore, since the back partition plate is fixed to the center combination united in this way, as a result, the back partition plate is aligned and fixed to the structure on the surface side.
[0010]
【The invention's effect】
As described above, according to the present invention, the center role is positioned and fixed to the game board, and the back partition plate is positioned and fixed to the center role. It is possible to provide a positioning structure of the back partition plate that can be accurately aligned and can easily align the structure on the front side and the structure on the back side. In particular, when a pilot hole for nailing is opened with a gauge plate as in a pachinko machine, other structures on the front side of the game board are aligned with the center accessory, and this center accessory is Since the back partition plate on the back side of the game board is aligned, the back partition plate is surely aligned with the structure on the front side, and smoothly guides the game ball passing from the front side to the back side of the game board be able to.
[0011]
Further, the invention according to claim 2 is a structure in which the front and back sides are structured via the center accessory when the center accessory is not only an integral part attached only from the front side but also the back side structure. The object can be easily aligned.

On the other hand, positioning holes 22 and 22 constituting the first positioning mechanism are formed at positions corresponding to the pins 43 and 43 in the peripheral portion on the surface side of the through hole 21 in the game board 20. The game board 20 is hit with a large number of nails which are obstacles to the game ball. The lower hole is used for positioning not only the nail but also around the winning opening and decorations, and the positioning holes 22 and 22 are simultaneously formed with the same punch. Therefore, the entire structure of the surface side structure is aligned. Further, the pin 43 inserted into the positioning hole 22 similar to the pilot hole has substantially the same diameter as the nail. The pins 43 and 43 are tapered at the tips, and the inner peripheral surfaces of the positioning holes 22 and 22 are also widened toward the opening side. It is guided to the position.
[0015]
A step portion 44 is formed so that the rear end portion of the square tube portion 41 in the center frame 40 becomes thinner inward by one step, and enters the opening portion 51 formed in the frame-shaped spherical path plate 50 from the inside. It can be fitted.
The ball path plate 50 is a part of the center role and also serves as the back partition plate, and is formed on the left back partition plate 52 and the right back partition plate 53 with respect to the short cylindrical projection 54 formed in the lower part thereof. The cap-shaped concave portion 55 is fitted and fitted and assembled. That is, the projection 54 and the recess 55 constitute a second positioning mechanism.
[0016]
The ball path plate 50, the left back partition plate 52, and the right back partition plate 53 are indicated by wavy lines in FIG. 1, and are positioned on the back side of the winning holes formed widely distributed on the game board 20. Then, each winning ball is guided to a predetermined position on the back side of the game board 20. For example, the ball path plate 50 guides the winning balls from the passage openings 23 and 23 arranged at the left and right of the game board 20 in the middle in the vertical direction, and the left back partition plate 52 and the right back partition plate 53 The winning balls from the normal winning holes 24, 24, 24, 24 formed on the left and right sides of the lower side of the game board 20, and the winning balls from the first type start opening 25 formed in the lower middle of the game board 20.
