Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine frame for a pachinko machine whose external dimensions can be adjusted. 2. Description of the Related Art Conventionally, as is well known, a pachinko machine has a structure in which left and right vertical frame plates and upper and lower horizontal frame plates are framed in a vertical rectangular shape, and left and right vertical frame plates are provided on the upper surface of a lower horizontal frame plate. A machine frame is assembled by mounting and fixing a waist plate connecting front lower ends of the machine frame, and a front frame that can be opened and closed forward is mounted on the front of the machine frame. By the way, this type of pachinko machine is available in the Kanto area specification (medium size) with the outer dimensions of the machine frame small, and the Kansai area specification (large size) with the machine frame slightly wider than the Kanto area specification. There are two types of things. Accordingly, as a countermeasure, a pachinko machine has emerged that can be used for both the normal size and the large size by expanding the pair of vertical frame plates and horizontal frame plates. [0003] However, in the pachinko machine, for example, when the pachinko machine is of a large size, the vertical frame plate on one side is horizontal with respect to the waistboard and the lower horizontal frame plate. Since it spreads in the direction, a step is generated between the waistboard and the lower horizontal frame plate and the vertical frame plate, and there is a problem that appearance is poor and commercial value is reduced. Moreover, since the vertical frame plate on the same side protrudes outside the one side end surface of the lower horizontal frame plate, a space area leading to the back surface of the pachinko machine is formed correspondingly, and this pachinko machine is attached to, for example, the island of the pachinko hall. When installed on a table, there is a problem that a player crawls a wire or the like on the back surface of the pachinko machine through the space area, and there is a risk that cheating may be performed. Therefore, the present invention has been made to solve the above-described problems, and in a pachinko machine frame that can be used as both a normal size and a large size, the appearance is not impaired even if the machine frame is expanded to a large size. It is another object of the present invention to provide a machine frame for a pachinko machine that does not have a possibility of performing wrongdoing. [0004] In order to achieve the above object, a pachinko machine frame of the present invention has a structure in which left and right vertical frame plates and upper and lower horizontal frame plates are framed in a vertically rectangular shape. A waistboard connecting the front lower ends of the left and right vertical frame plates is placed and fixed on the upper surface of the lower horizontal frame plate, and the distance between the pair of left and right vertical frame plates and the pair of upper and lower horizontal frame plates is set to the normal size. In a pachinko machine frame configured to be adjustable to a large size slightly wider than a normal size, a decorative cover plate having a large size is attached to a front surface of the waist plate so as to cover the front surface of the waist plate. The decorative cover plate has a closing plate protruding from a lower edge of one end thereof. Thus, even if the machine frame is expanded to a large size, the steps between the waistboard and the lower horizontal frame plate and the vertical frame plate are covered by the decorative cover plate, and the appearance is not impaired.
In addition, the front surface of the space region formed on one side end surface of the lower horizontal frame plate is also covered by the closing plate portion, and it becomes impossible to insert a wire or the like into the space region, thereby preventing fraud. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a pachinko machine according to an embodiment of the present invention; It was mentioned that there are two types of pachinko machines, normal size and large size.However, the front frame of the large size pachinko machine has a larger outer dimension by 10 mm in both the vertical and horizontal directions than the normal size pachinko machine.

The left vertical frame plate 16b is provided with a bracket 28 for pivotally supporting the lower portion of the front frame 2 so as to be openable and closable. The waist plate 18 is provided with a plurality of mounting holes 29 for mounting a decorative cover plate 19 on the front surface thereof in the longitudinal direction. The decorative cover plate 19 is made of a synthetic resin, and is formed in a horizontally long flat plate shape having the same vertical width as the waist plate 18. As shown in FIG. 7, a rectangular closing plate portion 30 is integrally protruded from a lower edge of one side end, and a bent piece portion bent rearward at a right angle to one side edge. 31 are provided. The vertical width L of the closing plate portion 30 is the lower horizontal frame plate 1.
7b, and the width M is such that when the space between the pair of left and right vertical frame plates 16a and 16b is a large size, the vertical frame plate 16a on the same side extends from one end face of the lower horizontal frame plate 17b. The width of the bent piece portion 31 is set to the same size as the thickness of the waist plate 18. On the front surface of the decorative cover plate 19, a design such as a pachinko machine name 32a is provided at the center and a plurality of horizontal ridges 32b are provided on both sides thereof.
This design is not limited to the drawing,
The colors can be freely selected according to the colors. The back surface is formed as a flat surface, and a plurality of cross-shaped projections 33 slightly thicker than the mounting holes 29 are provided at positions corresponding to the mounting holes 29 of the waist plate 18. Next, the case of manufacturing a large-sized machine casing 1b will be described in order. First, as shown in FIGS. 3, 5, and 6, the mounting holes 22, 22 of the L-shaped brackets 20a, 20b are provided.
And left and right vertical frame plates 16a, 16b and upper and lower horizontal frame plates 17
The screws 34, 34 are removed from the mounting holes 22, 22, with the positions of the mounting holes 25, 25 of
Screw into 5 and 25 to fix. Then, the waist plate 18 is placed and fixed on the upper surface of the lower horizontal frame plate 17b so as to be disposed at the front lower ends of the left and right vertical frame plates 16a and 16b. As a result, the frame 1a of the normal size shown by the chain line in FIG.
A large-sized machine frame 1b having an outer dimension enlarged vertically and horizontally by the distance (10 mm) between the mounting holes 21 and 22 formed in the mold fittings 20a and 20b is obtained. In the large-size machine frame 1b, as shown in FIG. 3, the right vertical frame plate 16a on the same side protrudes from one end surface (right side in the drawing) of the lower horizontal frame plate 17b. A space region P is formed. Therefore, as shown in FIG. 8, the decorative cover plate 19 is arranged on the front surface of the waist plate 18, and the projections 33 are pressed into the mounting holes 29 and mounted. At this time, while the waist plate 18 and the lower horizontal frame plate 17b are of a normal size, the decorative cover plate 19 is of a large size, so that one side of the decorative cover plate 19 as shown in FIGS. The end portion 19a projects outward from one end surface of the waist plate 18, the closing plate portion 30 is flush with the front surface of the lower horizontal frame plate 17b, and the bent piece portion 31 is the outer surface of the right vertical frame plate 16a. And become flush. Thus, the front surface of the space area P1 where the right vertical frame plate 16a protrudes from one end surface of the waist plate 18 is covered with the decorative cover plate 19, and the front surface of the space area P is also covered with the closing plate portion 30. Further, the side surfaces of both space regions P and P1 are covered by the bent piece portion 31. As described above, even in the large-sized machine frame 1b, in which the waist plate 18 and the lower horizontal frame plate 17b are of normal size, the large-sized decorative cover plate 19 allows the space regions P and P1 to be formed. Because it can be hidden, it doesn't detract from the design. In addition, the front surface of the space area P outside the one side end face of the lower horizontal frame plate 17b is
Since it is covered by 0, fraudulent acts performed through wires are also prevented. Although not shown, when a large waistboard is used, for example, the bent piece portion 31 becomes unnecessary.
The decorative cover plate 19 is provided with each mounting hole 29 of the waist plate 18.
It is also possible to remove the projections 33 by pulling them out. For example, when replacing the front frame 2 with a new one in a pachinko hall, the waist plate 18 also has a design that matches the front frame 2. If the pachinko machine is replaced with a new one, the design of the entire pachinko machine can be unified and the commercial value can be increased. As described above, the pachinko machine frame according to the present invention is a pachinko machine frame that can be used both in a normal size and a large size. A large-sized decorative cover plate attached to the front surface of the waistboard and the lower horizontal frame plate, the front of the space region where the vertical frame plate protrudes from one side end surface of the lower lateral frame plate protruding from the lower edge of one side end thereof Since the pachinko machine is covered by the closing plate portion, the appearance of the pachinko machine is not impaired, and the commercial value is enhanced. Moreover, when the pachinko machine is installed on the island stand of the pachinko hall, an illegal act is caused by wire or the like crawl on the back side of the pachinko machine through a space area formed outside one end surface of the lower horizontal frame plate. There is an effect that there is no possibility of the operation being performed.
