Claim Text:
1. An object collecting and discharging device of a combination weigher including first through sixth discharge paths, comprising: an inner collecting chute which has a hollow truncated inverted-cone shape having a vertical center axis; an outer collecting chute which has a hollow truncated inverted-cone shape and is placed outward relative to the inner collecting chute and concentrically with the inner collecting chute; wherein the inner collecting chute is sequentially divided into virtual first to eighth regions so as to have a center angle which is equal in a circumferential direction, when viewed from a vertical direction, a first discharge path having a first upper opening corresponding to a half of a lower opening of the inner collecting chute, which is defined by a lower end of the inner collecting chute which is located in the first to fourth regions, and a first lower opening which is placed on a straight line extending on a boundary between the second region and the third region and a boundary between the sixth region and the seventh region when viewed from the vertical direction, and located below the first upper opening, the first discharge path extending from the first upper opening to the first lower opening; a second discharge path having a second upper opening corresponding to a lower end of the inner collecting chute which is located in the first region and a lower end of a portion of the outer collecting chute which is located outward relative to the first region of the inner collecting chute, a third upper opening corresponding to a lower end of the inner collecting chute which is located in the fourth region and a lower end of a portion of the outer collecting chute which is located outward relative to the fourth region of the inner collecting chute, and a second lower opening which is placed on the straight line on the same side as a side where the first lower opening of the first discharge path is placed with respect to the center axis and located outward relative to the first lower opening, the second discharge path extending from the second upper opening and the third upper opening to the second lower opening; a third discharge path having a fourth upper opening corresponding to a lower end of the inner collecting chute which is located in the second region and the third region and a lower end of a portion of the outer collecting chute which is located outward relative to the second region and the third region of the inner collecting chute, and a third lower opening which is placed on the straight line on the same side as a side where the second lower opening of the second discharge path is placed with respect to the center axis, and located outward relative to the second lower opening, the third discharge path extending from the fourth upper opening to the third lower opening; a fourth discharge path having a fifth upper opening corresponding to a half of the lower opening of the inner collecting chute, which is defined by a lower end of the inner collecting chute which is located in the fifth to eighth regions, and a fourth lower opening which is placed on the straight line and located below the fifth upper opening, the fourth discharge path extending from the fifth upper opening to the fourth lower opening; a fifth discharge path having a sixth upper opening corresponding to a lower end of the inner collecting chute which is located in the fifth region and a lower end of a portion of the outer collecting chute which is located outward relative to the fifth region of the inner collecting chute, a seventh upper opening corresponding to a lower end of the inner collecting chute which is located in the eighth region and a lower end of a portion of the outer collecting chute which is located outward relative to the eighth region of the inner collecting chute, and a fifth lower opening which is placed on the straight line on the same side as a side where the fourth lower opening of the fourth discharge path is placed with respect to the center axis and located outward relative to the fourth lower opening, the fifth discharge path extending from sixth upper opening and the seventh upper opening to the fifth lower opening; and a sixth discharge path having an eighth upper opening corresponding to a lower end of the inner collecting chute which is located in the sixth region and the seventh region and a lower end of a portion of the outer collecting chute which is located outward relative to the sixth region and the seventh region of the inner collecting chute, and a sixth lower opening which is placed on the straight line on the same side as a side where the fifth lower opening of the fifth discharge path is placed with respect to the center axis and located outward relative to the fifth lower opening, the sixth discharge path extending from the eighth upper opening to the sixth lower opening.
