Stacking type tray and tray developing mechanism and stacking type tray developing system

A stacking type tray developing system, comprising:

• a stacking type tray formed by stacking a plurality of trays having tray operation portions not overlapping with other trays in thickness direction provided in circumferential sections;
• and a tray developing mechanism for forming a gap in a predetermined size between each of the trays by developing each of the trays of the stacking type tray, wherein
• the tray developing mechanism comprises:
• a tray distributing/holding portion including supporting portions for supporting each of the trays, which are provided by corresponding to the positions of the tray operation portions with the gap formed therebetween in the thickness direction so that each of the supporting portions do not overlap with each other in the thickness direction;
• and a tray distributing up/down table which moves up and down in the thickness direction along the tray distributing/holding portion by supporting a bottom-face of the tray located on a lowermost layer from a bottom side.
