DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame for a ball-and-ball game machine such as a pachinko machine, and more particularly, to a ball-and-ball game having a different external size by attaching and detaching a spacer plate to an outer side surface. The present invention relates to a machine frame configured to constitute a machine.

[0002]

2. Description of the Related Art Conventionally, in this type of gaming machine, an outer frame formed in a vertically long outer rectangular frame shape is exclusively used as an outer frame holding frame, and is formed in a square shape corresponding to a front opening area of the outer frame. A front frame openably and closably attached to the outer frame is a mounting frame for mounting a ball game component, and both frames (outer frame and front frame) constitute a machine frame body that holds the entire body. ing. Then, on the front frame that also functions as the mounting frame,
Various ball game components are mounted to form a ball game machine.

[0003] As the ball game component, for example,
Many various game components and related accessories including a window frame with a glass door, a set holding frame for a game board, upper and lower ball trays, a ball launcher and a ball feeder, a back mechanism set board having a ball processing mechanism, and the like. , Parts, and a game board or the like having a game content according to the model. These are mounted and set on each of the front and rear portions of the front frame to constitute a substantial ball game machine body. In this manner, a ball game machine is configured by combining the front frame, on which the ball game component members are mounted, and substantially constituting the ball game machine main body, with the outer frame serving as the outer frame holding frame. I am getting it. When installing a gaming machine in a pachinko hall or the like, first, an outer frame is fixedly held at a predetermined inclination in a housing portion of an installation frame stand commonly called “gaming island”, and the gaming machine body (that is, a ball game configuration) The front frame on which the members are mounted) is assembled to the outer frame.

[0004] In the ball game industry, the size of the accommodation portion of the installation frame in the above-mentioned "gaming island" varies from region to region, and when roughly classified, the so-called "Kansai frame" is widely used in the western Japan region. There are two types, the Kanto frame, which is widely used in the eastern Japan region, and the Kansai frame has a larger accommodation unit size than the Kanto frame. For this reason, the outer frame of the ball-and-ball game machine is made to have an outer size corresponding to the accommodation section of the small size "Kanto frame", and when attaching this to the "Kansai frame", at the manufacturing stage at the manufacturer, It is shipped after the spacer plate is nailed with nails or the like and the outer shell size is adjusted to the size of the Kansai frame.

However, in the method of hitting the spacer plate with a nail or the like as described above, when removing the spacer plate once attached due to a change in order or a change in the delivery destination, a great deal of labor is required to remove the spacer plate. In addition, there is a problem that scratches such as nails are formed on the spacer plate and the outer frame after the nail is removed, and the outer frame and the spacer plate cannot be used as a new product. In particular, the same spacer plate can be used regardless of the type of gaming machine body, and if the spacer plate can be reused when replacing the gaming machine, resources can be effectively used. However, there is a problem that it is difficult to re-use because nailing marks (holes) remain as described above. For this reason, Japanese Utility Model Laid-Open Publication No. 63-156679 discloses that a spacer plate is fastened to an outer frame by bolts and nuts. Scratch is less likely to occur.

[0006]

[Problems to be solved by the invention] By the way, "Kansai frame"
When comparing the "Kanto frame" with the "Kanto frame", the "Kansai frame" has a larger vertical and horizontal dimension than the "Kanto frame", When attaching to the "Kansai frame", it is necessary to attach a spacer plate of a predetermined thickness to either the upper or lower surface (generally the bottom surface) and the left or right side (generally the right side where the locking device is provided) of the outer frame There is. For this reason, conventionally, for example, a bottom spacer plate and a side spacer plate were prepared, and these spacer plates were respectively attached to the bottom surface and the right side surface of the outer frame. In this case, two types of spacer plates were prepared and managed. Therefore, there is a problem that the number of man-hours for management increases, and further, since it is necessary to attach each spacer plate separately, there is a problem that the number of man-hours for attaching also increases.

The present invention has been made in view of such a problem.
Spacer plates are attached to either one of the upper and lower sides and one of the left and right sides of the outer frame to reduce the man-hours required for management of the spacer plates before installation in a machine frame body that can be configured with a large external size. It is an object to reduce the number of work steps.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an outer frame formed in an outer rectangular frame shape and an outer frame formed in a square shape corresponding to a front opening area of the outer frame. In a ball game machine configured to have a front frame that is openably and closably attached to a ball game component mounted on the front frame,
An installation frame having an accommodating portion having a size larger than the outer size of the outer frame by attaching a spacer plate having a predetermined thickness to either the upper or lower outer surface or the left or right outer surface of the outer frame. It is configured so that it can be attached to a stand (for example, a so-called “Kansai frame”). At this time, the first attached to one of the upper and lower outer surfaces
A spacer plate (for example, the bottom spacer plate 70 in the embodiment) and a second spacer plate (for example, the side spacer plate 50 in the embodiment) attached to either one of the left and right outer surfaces form a connection portion having flexibility. And are integrally connected via the.

[0009] According to the machine frame of the ball game machine having such a configuration, the first and second spacer plates attached to either the upper or lower surface or the left or right outer surface of the outer frame are connected via the flexible connecting portion. Because it is configured to be connected integrally, it is only necessary to prepare and manage one spacer plate connected in this way,
It is possible to reduce man-hours for managing the spacer plate before mounting. Further, when attaching the thus connected spacer plates to the outer frame, for example, the first spacer plate portion is attached to one of the upper and lower outer surfaces, and in this state, the second spacer plate portion is bent at the flexible portion. The spacer plate may be attached to either the left or right outer surface, so that the attaching work of the spacer plate is simple and the number of working steps can be reduced.

When the outer frame 30 with the spacer plate attached thereto is nailed and fixed to the installation frame, it is preferable to form a nail escape opening for passing the nail through the spacer plate. In this way, in order to install the gaming machine on the `` gaming island '', for example, when nailing and fixing the upper and lower sides of the outer frame to the installation frame constituting the `` gaming island '' using a plurality of nails, It can be driven into the installation frame through the nail escape opening. Thus, no nailing hole is formed in the spacer plate, and the spacer plate can be reused as it is when the nail is pulled out and the gaming machine is removed from the installation frame.

Further, the front edge of the second spacer plate portion attached to one of the left and right side surfaces of the outer frame is projected forward to provide a protective edge, and the protective edge is attached to the outer frame in a closed state. It is preferable to set so as to cover the side surface of the frame. In this way, when the gaming machine with the spacer plate is mounted on a so-called "Kansai frame", the protective edge is located on the side of the front frame, and the locking device and the like are tampered with from the side of the front frame. Can be prevented from being performed.
