PURPOSE: To make it possible to box-pack by a specified weight and ship out fruit, etc., divided in classes by equipping a post shaped frame body which rockably supports a supporting frame and forms a contact part at the lower end part, a parallel link which exists between a fixed frame and the frame body and makes the frame body move vertically, and a scale which receives weight only by the contact part.

CONSTITUTION: Fruit divided in classes from a selection conveyor 4 reach a weighing box packing section 19 through a drawer conveyor, etc. At this weighing box-packing section 19, a supporting frame 21 which is supported by a post-shaped frame body 22 or an empty box B which is held by this supporting frame 21 tilt-moves to approach a feeding shoot 25, and is ascend-held, and the fruit, etc., from the drawer conveyor are drop-fed in the box B in order. The weight of these fruit and the supporting frame 21, etc., is received by a scale 20 at the lower end side contact part 22a through the post-shaped frame body 22. Also, since this post-shaped frame body 22 can vertically move in parallel by a parallel link 24, the weight added in the vertical direction is accurately and assuredly transmitted to the scale 20 side through the said contact part 22a. Also, when the fruit, etc., are let out to a carry-out conveyor side by descending the supporting frame 21 after weighing, an excessive force is not added to the scale 20 itself, since it is fixed-point-supported with the parallel link 24.
