Stocker and stocker system

A stocking system comprising:

• a case including a central portion therein, extending in a first direction, a longitudinal direction, and provided with a first storage portion and a second storage portion on both sides of the central portion in a second direction, a width direction;
• a shelf portion provided in the first storage portion and the second storage portion and having a plurality of shelves with an electronic component loaded thereon;
• a first port located in the first storage portion, and having a first open surface in which at least a portion of a side of the case is open in the second direction to communicate externally, the first port being a port through which the electronic component enters and exits;
• a second port located in the second storage portion, and having a second open surface in which at least a portion of the side of the case is open in the second direction to communicate externally, the second port being a port through which the electronic component enters and exits;
• a crane installed in the central portion and transferring the electronic component;
• and
• a mobile robot disposed on a first open surface side and transferring the electronic component into the first port,
• wherein the shelf portion includes shelf support members extending in the second direction, and, in the shelf portion, a pair of the shelf support members are spaced apart in a direction, parallel to the first direction, the pair of shelf support members having different lengths in the second direction.
