  By the way, in the pachinko machine, although dust does not easily collect in the upper part of the rib part, dust is collected between the rib part and the rib part. Therefore, it is desirable to remove the dust between the rib parts during maintenance. However, since the gap between the rib portions is an elongated groove with the upper surface of the base wall portion as the bottom surface, the operator cannot remove dust without using a brush or the like. Since the upper surface of the surface is inclined downward or horizontally, there is a problem in that it is difficult to scrape dust to the near side and the dust cannot be removed sufficiently.

  This invention is made | formed in view of this present condition, and aims at provision of the pachinko machine which is easy to remove the dust collected between the rib parts.

  The first aspect of the present invention is provided with a guide rail disposed on the front surface of the game board and defining a game area on the front surface of the game board. The game board discharges a game ball at a lower edge of the game area.

Is a base wall section that divides the game area at a position directly below the out mouth, and a substantially up-and-down direction that stands on the upper surface of the base wall section and guides the game ball to the out mouth by the upper guiding action. The pachinko machine is characterized in that the upper surface of the base wall part is inclined downward and forward.

  In such a configuration, since the upper surface of the base wall portion is inclined downward and forward, when the operator scrapes dust accumulated in the groove portion between the rib portions, the upper surface of the base wall portion constituting the bottom surface of the groove portion. This causes an action of guiding the dust forward, whereby the operator can scrape out the dust smoothly.

  According to a second aspect of the present invention, the out mouth guiding portion has a rib housing groove formed substantially along the front-rear direction on the upper surface, and a base wall portion that divides a game area at a position immediately below the out mouth, and the base A guide member that includes an elongated rib portion that fits into the rib portion receiving groove of the wall portion, and is held so that the rib portion can move up and down with respect to the rib portion receiving groove, and the rib portion is the base wall portion And an urging means for urging the guiding member at a position for guiding the game ball to the out-out port by the guiding action of the upper portion of the rib portion. By pushing down against the means, the guide member can be converted to a position where the upper surface of the rib portion is flush with the upper surface of the base wall portion. Here, the “urging means for urging the guide member” can be constituted by an elastic material, a coil spring, a weight or the like, and the leaf spring 44 corresponds to this in the following embodiment.

  In such a configuration, when removing the dust accumulated in the grooves between the ribs, the dust accumulated in the grooves between the ribs can be reduced by pressing down the guide member so that the upper surface of the base wall and the upper surface of the ribs are flush with each other. Can be exposed on an uneven surface. Therefore, according to this configuration, the operator can easily wipe off dust accumulated between the rib portions with a dust cloth or the like. It is desirable that the urging force by the urging means is strengthened to the extent that the guiding member is not displaced downward by the weight of the game ball falling on the out-port guiding portion.

  As described above, according to the first invention, the operator can easily scrape dust between the rib portions with a brush or the like during maintenance.

  Further, according to the second invention, since dust accumulated in the groove portion between the rib portions can be exposed on a surface having no irregularities, an operator can remove dust accumulated between the rib portions during maintenance. It can be removed easily and without any residue.
