Description

  The present invention relates to an outer frame of a gaming machine capable of ensuring support strength, expanding the inner method in the left-right direction, and facilitating material reuse.

An outer frame used in a gaming machine such as a pachinko gaming machine may be composed of a mixed material of wood and synthetic resin (see Patent Document 1), or from a metal plate inside the left and right pieces in a four-sided frame made of synthetic resin material. A reinforcing piece is attached (see Patent Document 2), composed of synthetic wood (see Patent Document 3), or composed of wood upper and lower pieces and metal left and right pieces (see Patent Document 4). It is known. However, there are drawbacks in that it is difficult to ensure the support strength for the front frame having a weight of about 20 kg, the expansion of the inner method in the left-right direction, the ease of material reuse, and the like.
