Description

  The present invention relates to a ball game machine such as a pachinko machine or an arrangement ball machine.

  In many ball game machines such as pachinko machines, a center case is arranged in the approximate center of the game area, and a liquid crystal display for production is mounted on the center case.

  By the way, the liquid crystal display used in this type of ball game machine has been steadily increasing in screen size. However, since a game nail or the like cannot be arranged on the front side of the liquid crystal display, the liquid crystal display can be used even in the game area. It is difficult to use the front range as a movable area of the game ball. In other words, in a ball game machine such as a pachinko machine, as the screen of the liquid crystal display becomes larger, the ratio of the movable area of the game ball to the game area gradually decreases, and the movement of the game ball is unified, which is unexpected. The reality is that it is poor in sex.

  Therefore, in order to increase the production effect by changing the movement of the game ball in such a limited movable area, for example, a game ball placed at the entrance of the stage by placing a stage on the lower side of the center case Ball game machines configured to roll freely on the stage in the horizontal direction and fall to the front have become mainstream.

Also, in order to further diversify the movement of game balls on the stage, for example, two stages are arranged at the front and rear, and the game balls that have entered the entrance are distributed to the two stages at the downstream branch. What was comprised in this is also known (for example, patent document 1).

The center of each of the passage holes 73 and 74 is that of the four branch plates 67. The center, that is, the center 55a of the branch portion 55 is arranged so as to coincide with the upper and lower sides.

  As described above, even when the game ball is branched into any of the four branch passages 53a to 53d, the four branch plates 67 are arranged radially at equal angular intervals from the center 55a of the branch portion 55, so that the first As in the embodiment, it is possible to make the distribution rate to each of the branch passages 53a to 53d substantially constant without variation among the gaming machines.

  In addition, when branching into three or five or more branch passages, it is possible to cope with the same by only changing the number of branch plates 67. Further, when the branch plates 67 are arranged radially, for example, the upper edge portions 67a thereof are formed in an inclined shape that decreases from the center 55a toward the outside, or an upward protruding portion is provided on the center 55a. Thus, it is possible to smoothly guide the game ball to each branch passage side.

  FIG. 13 illustrates the third embodiment of the present invention, and shows an example in which the branch plate 67 and the guide plates 71 and 72 are integrally formed.

  In this way, the branch plate 67 and the guide plates 71 and 72 are integrally formed by connecting, for example, the connecting portions 91 protruding upward from both ends in the width direction of the branch plate 67. By disposing the guide plates 71 and 72 integrally in the branch portion 55, it is possible to completely eliminate variations in the relative positional relationship between the branch plate 67 and the passage holes 73 and 74.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, in order to make the distribution ratio to each branch passage equal, for example, the passage holes 73 and 74 are arranged so that the centers thereof coincide with the center of the branch plate 67 in the plate thickness direction. , 74 may be slightly shifted from the center of the branch plate 67 in the plate thickness direction to give a difference in the distribution ratio to each branch passage.

  In the embodiment, a plurality of upper and lower guide plates 71 and 72 are provided with passage holes 73 and 74, respectively, so that the axial length of the passage holes is substantially long, but the passage holes are thick plates. The actual axial length of the passage hole may be increased by providing it or the like. In the case where a plurality of guide plates provided with passage holes are vertically arranged, the interval between them is preferably smaller than the diameter of the game balls, but may be larger than the diameter of the game balls. In this case, it is desirable to provide an inclined portion or the like for guiding the game ball to the passage hole side on the upper surface side of all the guide plates. The through holes 73 and 74 do not have to be circular, and may be polygons such as hexagons and octagons.
