PROBLEM TO BE SOLVED: To surely remove the leavings in lunch boxes of different sizes by mounting a curved guide part on a third chuter, and movably mounting an eccentric cam member for adjusting a clearance between the guide part and a second chutter, between the guide part and the second chuter. SOLUTION: A third chuter 11 is provided with a curved guide part 11a on a part corresponding to an end of a second chuter 9. An eccentric cam member 12 for adjusting a clearance between the end of the second chuter 9 and the guide part 11a by the positioning on the basis of the rotation of the eccentric cam member 12, is mounted on the second chuter 9 side. An attitude reversing means 10 capable of rotating and moving a tapping piece 15 formed by a leather belt and fixed to a shaft 17, is mounted on the opposite side. When a box body 3 is dropped from the second chuter 9, the rotating tapping piece 15 is collided with the box body 3 to reverse the attitude of the box body 3 and to remove the leavings such as leftover rice. In a case when a lunch box different in size is to be disposed, the eccentric cam member 12 is reset.
