A combination weighing apparatus comprising: a plurality of hoppers that receives articles inputted from an outside, temporarily stores the articles, and discharges the stored articles downstream; a discharge chute that receives the articles discharged from the hoppers and causes the articles to slide downstream; an acquisition unit that acquires weight values of the articles stored in each hopper ; and a control unit that performs combination calculation on the basis of the weight values acquired by the acquisition unit and discharges the articles from a hopper determined by the combination calculation to the discharge chute , characterised in that the discharge chute includes: a first slide surface having a plurality of openings ; and for each opening, a second slide surface that covers a part of the opening and is disposed at a position on an inner side of the discharge chute with respect to the first slide surface , and the second slide surface is formed continuously with the first slide surface on an upstream side, a left side, and a right side of the opening, and each second slide surface includes: a left flat surface rising from the first slide surface toward the inner side on a left side of the opening ; a right flat surface rising from the first slide surface toward the inner side on a right side of the opening ; and an upper flat surface that connects the left flat surface with the right flat surface . a plurality of hoppers that receives articles inputted from an outside, temporarily stores the articles, and discharges the stored articles downstream; a discharge chute that receives the articles discharged from the hoppers and causes the articles to slide downstream; an acquisition unit that acquires weight values of the articles stored in each hopper ; and a control unit that performs combination calculation on the basis of the weight values acquired by the acquisition unit and discharges the articles from a hopper determined by the combination calculation to the discharge chute , characterised in that the discharge chute includes: a first slide surface having a plurality of openings ; and for each opening, a second slide surface that covers a part of the opening and is disposed at a position on an inner side of the discharge chute with respect to the first slide surface , and a first slide surface having a plurality of openings ; and for each opening, a second slide surface that covers a part of the opening and is disposed at a position on an inner side of the discharge chute with respect to the first slide surface , and the second slide surface is formed continuously with the first slide surface on an upstream side, a left side, and a right side of the opening, and each second slide surface includes: a left flat surface rising from the first slide surface toward the inner side on a left side of the opening ; a right flat surface rising from the first slide surface toward the inner side on a right side of the opening ; and an upper flat surface that connects the left flat surface with the right flat surface . a left flat surface rising from the first slide surface toward the inner side on a left side of the opening ; a right flat surface rising from the first slide surface toward the inner side on a right side of the opening ; and an upper flat surface that connects the left flat surface with the right flat surface . <EOS>
