Hereinafter, an operation of detecting the size of the article by the article size detecting device 1c will be described. First, the classified item A is set on the upper surface of the base 10. Then, the cylinder 11 elongates the piston rod 11a and lowers the measuring device 12. At this time, the measuring piece 12b is pressed to the article A. Thereby, the measuring member 12b moves toward the inside of the main body portion 12a, and the protruding length from the main body portion 12a is reduced.

The amount of movement of the measuring piece 12b at this time is a value corresponding to the size (height size H) of the article A. That is, the amount of movement of the measuring member 12b increases as the article A increases. Thereby, the measuring device 12 can detect the size of the article A based on the amount of movement of the measuring member 12b.
